Research advances in noninvasive diagnostic methods for nonalcoholic steatohepatitis
Hu MengQi, Xu YouQing, Zhang Tao, Xu HongTuan
2017, 33(12): 2288-2291. DOI: 10.3969/j.issn.1001-5256.2017.12.006
Abstract:
Nonalcoholic fatty liver disease ( NAFLD) has become the most common liver disease in the world in terms of incidence rate and is gradually becoming the first cause of liver transplantation in developed countries. The spectrum of this disease includes simple fatty liver, nonalcoholic steatohepatitis ( NASH) , liver fibrosis, and liver cirrhosis. Compared with simple fatty liver, NASH is not a benign disease and can progress to advanced cirrhosis and liver cancer. At present, liver biopsy remains the gold standard for the diagnosis of NASH, but its application is limited by its invasive and potential complications. Noninvasive diagnostic methods have been developed for the diagnosis of NASH in clinical practice to replace liver biopsy; however, there still lack mature and reliable noninvasive methods, and continuous efforts should be made for further exploration and modification. This article reviews the recent research advances in noninvasive diagnostic methods for NASH in China and foreign countries.

2017, 33(12): 2292-2295. DOI: 10.3969/j.issn.1001-5256.2017.12.007
Abstract:
Research and development of investigational new drugs for nonalcoholic fatty liver disease is now a research hotspot in the field of liver disease. However, there are still great challenges in protocol design and implementation in phase II/III clinical trials. Since there are still controversies over the exact histological definition of nonalcoholic steatohepatitis in the academic world and a lack of long-term large-scale studies on the natural history and clinical pathology of nonalcoholic fatty liver disease/nonalcoholic steatohepatitis, we still face a lot of challenges in the selection and definition of study population, selection of study endpoints, and interpretation of true clinical value. In addition, such clinical trials often have various confounding factors, which should be controlled as much as possible in protocol design and implementation, in order to minimize the bias in research conclusions.
Hepatic fibrosis in nonalcoholic fatty liver disease and its quantitative assessment
Wang Yan, Hou JinLin
2017, 33(12): 2296-2302. DOI: 10.3969/j.issn.1001-5256.2017.12.008
Abstract:
Nonalcoholic fatty liver disease ( NAFLD) is becoming a primary etiology underlying the chronic liver injury-related fibrogenesis among general population. Histologic fibrosis has been demonstrated as the most important independent predictor for the major outcomes of NAFLD patients. NAFLD-related fibrosis has distinct characteristics through the disease course, which is largely attributed to its " metabolic" pathophysiology: The progression of fibrosis is correlated to the factors including obesity, metabolic syndrome components, aging, etc.;and the patterns of histologic distribution and evolution as well as the association with the other histological features are remarkably different from those of the other chronic liver diseases. Based on the criteria of current standard histology, accurate quantitative assessment of NAFLD fibrosis could be relevant in terms of research and utilization to stratifying the disease risk, monitoring the therapeutic response, as well as to facilitating the development of new diagnostic tools.
Role of histological evaluation of the liver in clinical practice and research on nonalcoholic fatty liver disease
Jiang LiNa, Zhao JingMin
2017, 33(12): 2303-2306. DOI: 10.3969/j.issn.1001-5256.2017.12.009
Abstract:
Liver biopsy is currently the gold standard for the diagnosis of nonalcoholic fatty liver disease ( NAFLD) , especially nonalcoholic steatohepatitis ( NASH) . Although liver biopsy has the limitations such as invasiveness, sampling error, and evaluation error, in clinical trials of NAFLD/NASH and related new drugs, it is still used to evaluate the enrollment of patients into a cohort and primary and/or secondary endpoints and cannot be replaced by other methods. The histological evaluation systems of NAFLD/NASH mainly include Brunt system, NASH-CRN scoring system, European SAF/FLIP scoring algorithm, and pediatric NAFLD histological scoring system, and an appropriate histological scoring system should be selected in clinical practice and research.
Role of imaging techniques in clinical research and practice on nonalcoholic fatty liver disease
Wang Yi
2017, 33(12): 2307-2310. DOI: 10.3969/j.issn.1001-5256.2017.12.010
Abstract:
Abdominal ultrasound ( US) , computed tomography ( CT) , and magnetic resonance imaging ( MRI) have been used in the clinical diagnosis and management of nonalcoholic fatty liver disease ( NAFLD) . This article elaborates on the advantages and limitations of US, CT, and MRI in the evaluation of NAFLD. Compared with conventional imaging examinations, multi-parametric quantitative MRI allows for comprehensive and objective evaluation of NAFLD. Proton density fat fraction ( PDFF) is considered the gold standard for the diagnosis of fatty liver disease and has been applied in clinical research. Independent clinical studies in adults and children have confirmed the practicability, reliability, and transformative quality of PDFF using various MRI scanning systems and software. Magnetic resonance elastography is used to evaluate the degree of liver fibrosis and is not affected by hepatic steatosis. In patients with NAFLD, MRI can measure hepatic fat deposition and fibrosis in a single examination and, to a certain degree, it can replace liver biopsy.

Wu XiaoLi
2017, 33(12): 2311-2315. DOI: 10.3969/j.issn.1001-5256.2017.12.011
Abstract:
Objective To investigate the influence of the sequence of PEG-IFNα-2 a and adefovir dipivoxil ( ADV) on the clinical outcome of patients with HBe Ag-positive chronic hepatitis B ( CHB) . Methods A total of 86 patients with HBe Ag-positive CHB who were treated in Yucheng People's Hospital from September 1, 2011 to November 1, 2013 were enrolled and randomly divided into groups A ( 28 patients, among whom one dropped out in the late stage) , B ( 29 patients, among whom two dropped out in the late stage) , and C ( 29 patients, among whom three dropped out in the late stage) . All patients were treated with PEG-IFNα-2 a combined with ADV; the patients in group A were given PEG-IFNα-2 a and ADV concurrently, those in group B were given PEG-IFNα-2 a for 24 weeks, followed by PEG-IFNα-2 a combined with ADV, and those in group C were given ADV for 24 weeks, followed by PEG-IFNα-2 a combined with ADV. The course of treatment was 60 weeks for all groups. The patients were followed up for 24 weeks after drug withdrawal. The three groups were compared in terms of clinical outcome [HBe Ag disappearance rate and seroconversion rate, HBs Ag clearance rate, HBV DNA clearance rate, and alanine aminotransferase ( ALT) normalization rate]. An analysis of variance or t test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. Results After 60 weeks of treatment, there were significant differences in HBe Ag disappearance rate and seroconversion rate between the three groups ( 85. 2% vs81. 5% vs 69. 2%, χ2= 6. 253, P < 0. 05) , and groups A and B had significantly higher rates than group C ( all P < 0. 012 5) ; there was a significant difference in HBV DNA clearance rate between the three groups ( 81. 5% vs 55. 6% vs 80. 8%, χ2= 7. 409, P < 0. 05) , and groups A and C had a significantly higher rate than group B ( both P < 0. 012 5) ; there was a significant difference in ALT normalization rate between the three groups ( 81. 5% vs 80. 8% vs 57. 7%, χ2= 7. 425, P < 0. 05) , and group A had a significantly higher rate than group C ( P < 0. 012 5) . After 24 weeks of drug withdrawal, there were significant differences in HBe Ag disappearance rate and seroconversion rate between the three groups ( 81. 5% vs 81. 5% vs 65. 4%, χ2= 6. 723, P < 0. 05) , and groups A and B had significantly higher rates than group C ( all P < 0. 012 5) ; there was a significant difference in ALT normalization rate between the three groups ( 81. 5% vs 74. 1% vs53. 8%, χ2= 9. 690, P < 0. 05) , and group A had a significantly higher rate than group C ( P < 0. 012 5) . Most adverse reactions occurred within 24 weeks of treatment and mainly manifested as influenza-like symptoms such as low-grade fever, headache, and sore muscle, and most of the patients were relieved spontaneously without intervention. Some patients experienced bone marrow suppression manifesting as reductions in leukocytes, neutrophils, and platelets and were relieved after the treatment with granulocyte colony-stimulating factor. Conclusion ADV given at first to reduce HBV DNA and followed by the addition of PEG-IFNα-2 a can achieve a similar effect as ADV given concurrently with PEG-IFNα-2 a and has certain significance in shortening the duration of PEG-IFNα-2 a treatment and reducing the dose of PEG-IFNα-2 a.

Abstract:
Objective To observe the clinical effect of Mongolian medicine Qinggan Jiuwei powder in the treatment of alcoholic liver fibrosis by observing the improvement in imaging indices. Methods A total of 104 patients with alcoholic liver fibrosis who visited Department of Gastroenterology in Horqin District First People's Hospital in Tongliao from October 2015 to January 2017 were enrolled and randomly divided into experimental group and control group, with 52 patients in each group. The patients in the experimental group were given Mongolian medicine Qinggan Jiuwei powder, while those in the control group were given reduced glutathione tablets. Liver function parameters, liver-spleen ultrasound findings, and liver stiffness measurement ( LSM) determined by Fibro Scan were observed before and after treatment. The independent samples t-test was used for comparison of normally distributed continuous data between groups, and the paired samples t-test was used for comparison within each group; the Wilcoxon rank sum test was used for comparison of non-normally distributed continuous data between groups. Results Both groups had varying degrees of improvements in clinical symptoms and signs. Both groups had significant changes in alanine aminotransferase, aspartate aminotransferase ( AST) , gamma-glutamyl transpeptidase ( GGT) , and LSM after treatment ( experimental group: Z =-3. 09, -7. 19, and-8. 27, t = 7. 13, P = 0. 002, < 0. 001, < 0. 001, and < 0. 001; control group: Z =-3. 28, -4. 60, and-5. 06, t = 8. 54. P = 0. 001, < 0. 001, < 0. 001, and < 0. 001) . There were significant differences in AST and GGT after treatment between the two groups ( Z =-2. 02 and-2. 15, P = 0. 04 and 0. 03) . Both groups had significant changes in oblique diameter of the right liver lobe, diameter of the portal vein, blood flow rate of the portal vein, spleen thickness, and diameter of the splenic vein after treatment ( experimental group: t = 6. 48, 11. 02, 2. 20, 3. 30 and 5. 30, P < 0. 001, < 0. 001, = 0. 030, < 0. 001, and < 0. 001;control group: t = 3. 51、6. 31、2. 68、3. 06、4. 71, P = 0. 01, < 0. 001, = 0. 01, < 0. 001, and < 0. 001) . There were significant differences in oblique diameter of the right liver lobe and diameter of the portal vein after treatment between the two groups ( t = 3. 96 and 3. 53, P = 0. 02 and 0. 01) . Conclusion Mongolian medicine Qinggan Jiuwei powder has a good clinical effect in the treatment of alcoholic liver fibrosis and can effectively reduce the imaging index LSM and values measured by abdominal color Doppler ultrasound in patients with alcoholic liver fibrosis.

2017, 33(12): 2321-2325. DOI: 10.3969/j.issn.1001-5256.2017.12.013
Abstract:
Objective To investigate the short-and long-term efficacy of endoscopic sclerotherapy with lauromacrogol in the treatment of cirrhotic patients with severe esophageal variceal bleeding. Methods A retrospective analysis was performed for the clinical data of 160 patients who underwent endoscopic sclerotherapy with lauromacrogol for the first time due to severe esophageal variceal bleeding caused by cirrhotic portal hypertension in The Fifth Hospital of Shijiazhuang from January 2011 to December 2014. These patients were divided into emergency treatment group with 66 patients and selective treatment group with 94 patients. All patients were followed up for 1-5 years, and a statistical analysis was performed for the success rate of hemostasis, short-term rebleeding rate, long-term rebleeding rate, and incidence of complications. The chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups, and the t-test was used for comparison of continuous data between two groups. Results There were no significant differences between the emergency treatment group and the selective treatment group in the success rate of hemostasis ( 98. 48% vs 100. 00%, P > 0. 05) , rate of eradication or disappearance of varices ( 74. 24% vs 82. 98%, P > 0. 05) , time to the eradication or disappearance of varices ( 21. 4 ± 0. 3 d vs 20. 5 ±0. 3 d, P > 0. 05) , variceal recurrence rate ( 18. 18% vs 15. 96%, P > 0. 05) , time to variceal recurrence ( 17. 0 ± 1. 8 months vs 19. 2 ±2. 3 months, P > 0. 05) , long-term rebleeding rate ( 33. 33% vs 21. 28%, P > 0. 05) , and incidence rate of complications ( 22. 73% vs18. 09%, P > 0. 05) , while there was a significant difference in short-term rebleeding rate between the two groups ( 9. 09% vs 1. 06%, P = 0. 020) . Of all 160 patients, 8 ( 5. 00%) died during follow-up, including 5 patients in the emergency treatment group ( one each died of esophageal variceal bleeding, multiple organ failure, and rupture and bleeding of liver cancer nodules, and 2 died of hepatic encephalopathy) and 3 in the selective treatment group ( one patient each died of esophageal variceal bleeding, multiple organ failure, and rupture and bleeding of liver cancer nodules) . Conclusion Endoscopic sclerotherapy with lauromacrogol has marked short-and long-term efficacy in the treatment of severe esophageal variceal bleeding, and short-term rebleeding after emergency treatment should be taken seriously.

Lu NingNing, Sun Bin, Cui XiongWei, Long Jiang, Gao WenFeng, Zheng JiaSheng
2017, 33(12): 2326-2330. DOI: 10.3969/j.issn.1001-5256.2017.12.014
Abstract:
Objective To investigate the diagnosis and treatment of subcapsular hemorrhage caused by liver tumor ablation. Methods A retrospective analysis was performed for the clinical data of 1596 patients who underwent CT-guided liver tumor microwave/radiofrequency ablation in Beijing You An Hospital, Capital Medical University, from January 2016 to July 2017, and among these patients, 20 experienced subcapsular hemorrhage after ablation. The clinical data of the 20 patients were collected, and their diagnostic method, treatment regimen, and prognosis were analyzed. The chi-square test was used for comparison of categorical data between groups. Results Among the 638 patients who underwent microwave ablation, 10 experienced subcapsular hemorrhage, resulting in an incidence rate of 1. 57%; among the 958 patients who underwent radiofrequency ablation, 10 experienced subcapsular hemorrhage, resulting in an incidence rate of 1. 04%; there was no significant difference in the incidence rate of this complication between the two groups ( χ2= 0. 848, P = 0. 357) . Among the 20 patients, 17 were found to have spillage of the contrast media on contrast-enhanced CT immediately after ablation; 3 had negative findings on contrast-enhanced CT immediately after ablation and were found to have hemorrhage within 24 hours after ablation, and transcatheter arterial embolization ( TAE) was performed after a definite diagnosis was made by emergency CT. Of all 20 patients with hemorrhage, 2 were complicated by gallbladder hemorrhage; 19 underwent TAE, among whom 6 had the leakage of the contrast agent on angiography. The patients were followed up for 1-3 months, and all of them recovered well; there were no deaths. Conclusion Subcapsular hemorrhage is one of the serious complications after liver tumor ablation, and contrast-enhanced CT immediately after ablation can find most cases of bleeding. Patients with mild hemorrhage can be given symptomatic and conservative treatment first, and TAE should be performed as early as possible for patients with active arterial hemorrhage or who do not respond to conservative treatment.

Xing ZhiXiang, Shen ShiQiang, Qin Feng, Yang Qiang, Ye Zi
2017, 33(12): 2331-2336. DOI: 10.3969/j.issn.1001-5256.2017.12.015
Abstract:
Objective To investigate the effect of postoperative adjuvant transarterial chemoembolization ( TACE) on the survival of patients with hepatocellular carcinoma ( HCC) , as well as influencing factors for prognosis. Methods A retrospective analysis was performed for the clinical data of 215 HCC patients who were admitted to Renmin Hospital of Wuhan University from January 2007 to December 2012. According to whether TACE was given after hepatectomy, these patients were divided into single group with 95 patients and combination group with120 patients. A comparative analysis was performed for the two groups. The patients in the single group were given hepatectomy alone, and those in the combination group were given hepatectomy followed by TACE at one month after surgery. General status, treatment condition, and related clinical indices were recorded for both groups, and the two groups were compared in terms of the 1-, 3-, and 5-year survival rates and disease-free survival rates after surgery. The independent samples t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. The Kaplan-Meier method was used for comparison of survival rates between groups, and univariate analysis and Cox multivariate regression analysis were used to investigate the influencing factors for prognosis after hepatectomy. Results In the combination group, the 1-, 3-, and 5-year survival rates were 96. 5%, 67. 0%, and 51. 0%, respectively, with a median survival time of 51 months; in the single group, the 1-, 3-, and 5-year survival rates were 84. 0%, 49. 5%, and 36. 5%, respectively, with a median survival time of 39 months; there was a significant difference in survival rates between the two groups ( χ2= 5. 540, P = 0. 018) . The 1-, 3-, and 5-year disease-free survival rates were 91. 7%, 62. 5%, and 37. 5%, respectively, in the combination group and 84. 0%, 42. 1%, and 26. 3%, respectively, in the single group, and there was a significant difference between the two groups ( χ2= 4. 942, P = 0. 027) . Preoperative alpha-fetoprotein > 400 μg/L, TNM stage III, multiple tumors, tumor diameter > 5 cm, positive HBs Ag, and vascular invasion were independent prognostic factors in patients after hepatectomy, while TACE was a protective factor for long-term survival of these patients. Conclusion Adjuvant TACE after hepatectomy can significantly improve the survival rate and disease-free survival rate of HCC patients and has great significance in improving surgical outcome.

Li Huan, Sun Jing, Zhang Tao, Fan YuZe, Sun YingZhe, He WeiPing, Duan XueZhang
2017, 33(12): 2337-2341. DOI: 10.3969/j.issn.1001-5256.2017.12.016
Abstract:
Objective To investigate the clinical effect of Cyber Knife radiosurgery, a type of stereotactic body radiotherapy, in the treatment of recurrent liver cancer after resection or ablation, as well as the effect of clinical factors on survival rate. Methods A retrospective analysis was performed for the clinical data of 34 patients with recurrent liver cancer after surgery who were treated with Cyber Knife radiosurgery. The patients' survival rate and survival time after radiotherapy were calculated, and the influencing factors for survival were analyzed.The gross tumor volume of tumor target was 1. 475-1082. 075 cm3 ( median 162. 99 cm3) . The fraction dose was 7-20 Gy ( median 9 Gy) , the number of times of irradiation was 2-8 times ( median 5 times) , and the tumor dose was 24-60 Gy ( median 45 Gy) once a day. The major indices for observation were short-term outcome, toxic and side effects, and long-term outcome. The log-rank test was used to analyze the surviral-related factors. The chi-square test and fisher test were used for comparison of categorical data between groups. Results The 1-, 2-, and 3-year overall survival rates after radiotherapy were 91. 2%, 70. 6%, and 44. 1%, respectively, and the median survival time was 34 months. The 1-, 2-, and 3-year progression-free survival rates were 55. 9%, 38. 2%, and 29. 4%, respectively.There were no significant differences in 1-, 2-, and 3-year overall survival rates after radiotherapy between the ≤1-year ( early) postoperative group and the > 1-year ( late) postoperative group ( 89%/73. 7%/57. 9% vs 93%/73. 3%/33. 3%, χ2= 0. 354, P = 0. 368) .The univariate analyses showed that sex, age, time to postoperative recurrence, diameter and number of recurrent lesions, liver function classification, alpha-fetoprotein level, and chemotherapy were not significantly associated with patients' survival after radiotherapy. Conclusion Cyber Knife radiosurgery is safe and effective in the treatment of recurrent liver cancer, with the advantages of good local control of liver cancer, a high overall survival rate, noninvasiveness, few side effects, and good tolerability, and thus provides a new direction for the treatment of intrahepatic recurrence of primary liver cancer.

Xia Geng, Qi Fei, Yang JinHui, Tang YingMei, Shi MengLin, Zhang JunQi
2017, 33(12): 2342-2345. DOI: 10.3969/j.issn.1001-5256.2017.12.017
Abstract:
Objective To investigate the expression of nuclear factor-kappa B ( NF-κB) p65 in cancer tissue and adjacent tissue using hepatoma tissue microarray, as well as its significance in the development and progression of hepatocellular carcinoma ( HCC) . Methods The hepatoma tissue microarray HLiv H180 Su05 was used to analyze 81 cancer tissue samples and 81 adjacent tissue samples. Surgery was performed from May 2006 to May 2007, and the patients were followed up to February 2012. Of all patients, 46 experienced recurrence and35 did not experience recurrence. According to the TNM staging of gallbladder carcinoma developed by the American Joint Committee on Cancer, 56 had stage I tumor and 25 had stage II tumor; 28 had tumor thrombus and 53 had no tumor thrombus. Immunohistochemistry was used to measure the expression of NF-κB p65, and its association with other factors was analyzed. On the basis of the localization of the protein to be measured, a comprehensive evaluation was performed based on the intensity of positive signal and the number of positive cells.The chi-square test was used for comparison of categorical data between groups, the Kaplan-Meier method was used for survival analysis, and the log-rank test was used for the comparison of survival rates. Results NF-κB p65 protein was located in the cytoplasm and some nuclei in cancer tissue and adjacent tissue, with positive rates of 90. 12% in the cancer tissue and 69. 14% in the adjacent tissue, and there was a significant difference in positive rate between the cancer tissue and the adjacent tissue ( χ2= 10. 998, P = 0. 001) . The expression of NF-κB p65 protein in cancer tissue was not associated with clinical stage, tumor thrombus, or the presence or absence of recurrence ( all P > 0. 05) . Conclusion HCC tissue has higher expression of NF-κB p65 than adjacent tissue. The key to the regulation of NF-κB function is to inhibit the promotional effect of Rel A ( p65) on liver tumor. Therefore, inhibiting the activity of NF-κB p65 may suppress the differentiation and growth of tumor cells, providing a new idea for clinical treatment of HCC.

2017, 33(12): 2346-2349. DOI: 10.3969/j.issn.1001-5256.2017.12.018
Abstract:
Objective To investigate the etiology of recurrent acute pancreatitis ( RAP) and selection of treatment regimen. Methods A retrospective analysis was performed for the clinical data of 284 patients with acute pancreatitis ( AP) who were admitted to The Second People's Hospital of Neijiang from January 2012 to December 2015, and among these patients, 232 had incipient AP ( incipient group) and 52 had RAP ( recurrent group) . The two groups were analyzed in terms of general status, etiology, number of times of recurrence, recurrence interval, treatment regimen, and prognosis. The t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. Results Compared with the incipient group, the recurrent group had a significantly higher proportion of patients with biliary factors ( 66. 8% vs 35. 8%, χ2= 7. 109, P = 0. 008) or hyperlipidemia ( 17. 3% vs16. 0%, χ2= 5. 818, P = 0. 007) , as well as a significantly lower proportion of patients with diet factors ( 7. 7% vs 21. 1%, χ2= 5. 046, P = 0. 025) . Among the 52 patients in the recurrent group, 33 ( 63. 46%) had one time of recurrence, 14 ( 26. 92%) had two times of recurrence, and 5 ( 9. 62%) had three or more times of recurrence; as for recurrence interval, 12 ( 23. 08%) had a recurrence interval of less than 6 months, 23 ( 44. 23%) had a recurrence interval of 6-12 months, and 17 ( 32. 69%) had a recurrence interval of more than 12 months; as for the selection of treatment regimen, 23 underwent surgical treatment, 23 underwent conservative treatment, and 6 underwent endoscopic therapy. These patients were followed up for 6-24 months, and no patient died or experienced recurrence. Conclusion RAP has a complex etiology, and biliary factors and hyperlipidemia are closely associated with the recurrence of AP. Identification of etiology and active etiological treatment can effectively reduce the recurrence rate of AP.

2017, 33(12): 2350-2354. DOI: 10.3969/j.issn.1001-5256.2017.12.019
Abstract:
Objective To investigate the association between hypertriglyceridemia and acute pancreatitis in patients with type 2 diabetes, in order to guide the prevention and treatment of acute pancreatitis in patients with diabetes. Methods A total of 46 patients with type 2 diabetes complicated by acute pancreatitis who were admitted to The First Hospital of Yulin from January 2013 to December 2016 were enrolled as study group, and 52 patients with type 2 diabetes alone who were admitted to our hospital within the same period of time were enrolled as control group. Related data were recorded, including age, sex, course of diabetes, body height and weight, abdominal circumference, smoking, drinking, gallstones, hypertension, blood glucose, and blood lipids [total cholesterol ( TC) , triglyceride ( TG) , high-density lipoprotein cholesterol ( HDL-C) , and low-density lipoprotein cholesterol ( LDL-C) ]. The incidence rates of complications associated with diabetes were analyzed. The chi-square test was used for comparison of categorical data ( general status, blood lipids, and diabetic complications) between two groups; and the t-test was used for comparison of such data between two groups. A logistic regression analysis was used for multivariate analysis. Results There were no significant differences between the two groups in age, sex composition, body height and weight, abdominal circumference, smoking and drinking habits, hypertension, gallstones, and course of diabetes ( all P >0. 05) . The study group had significantly higher levels of TC, TG, and LDL-C than the control group ( t = 5. 122, 4. 127, and 3. 524, P < 0. 01, < 0. 01, and = 0. 012) , while the control group had a significantly higher level of HDL-C than the study group ( t = 2. 231, P = 0. 037) . The study group had a significantly higher incidence rate of diabetic microangiopathy ( diabetic retinopathy and chronic diabetic nephropathy) than the control group ( χ2= 92. 126, P < 0. 01) . The multivariate analysis showed that compared with those with a normal TG level, the type 2 diabetic patients with a high TG level had a risk of acute pancreatitis increased by 47. 6% ( odds ratio [OR]= 1. 476, P =0. 031) , and the type 2 diabetic patients with a high LDL-C level had a risk of acute pancreatitis increased by 48. 7% ( OR = 1. 487, P =0. 045) . Conclusion Blood lipids should be measured for patients with type 2 diabetes, and blood glucose and blood lipid levels should be actively controlled for patients with type 2 diabetes complicated by hypertriglyceridemia, in order to reduce the incidence rate of acute pancreatitis.

Ding YuPing, Li Hai, Zhang Wen, Xia ShiHai, Bi Xun
2017, 33(12): 2355-2360. DOI: 10.3969/j.issn.1001-5256.2017.12.020
Abstract:

Objective To investigate the epidemiological characteristics of nonalcoholic fatty liver disease ( NAFLD) with elevated alanine aminotransferase ( ALT) and related risk factors. Methods A total of 1007 patients with NAFLD who were admitted to The Affiliated Hospital of Logistics University of Chinese People's Armed Police Forces from April 4, 2016 to September 13, 2016 were enrolled, and among these patients, 123 had an elevated ALT level ( higher than the upper limit of normal 50 U/L) ( elevated ALT group) and 884 had normal ALT ( normal ALT group) . A statistical analysis was performed for their general data and laboratory markers [number of peripheral blood mononuclear cells, fasting blood glucose, triglyceride ( TG) , total cholesterol ( TC) , high-density lipoprotein ( HDL) , low-density lipoprotein ( LDL) , LDL/HDL ratio, ALT, aspartate aminotransferase ( AST) , gamma-glutamyl transpeptidase ( GGT) , alkaline phosphatase ( ALP) , uric acid ( UA) , creatinine, blood urea nitrogen, urinary protein, urinary microproteins], blood pressure, body mass index ( BMI) , concomitant biliary disease, and thyroid nodules. The t-test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups. A multivariate logistic regression analysis was used to identify the risk factors for elevated ALT in NAFLD patients. Results Among the 1007 patients with NAFLD, there were 752 male and 255 female patients.Of all male patients, 13. 7% ( 103/752) were in the elevated ALT group, and of all female patients, 7. 8% ( 20/255) were in the elevated ALT group; there was a significant difference in the prevalence rate between male and female patients ( χ2= 5. 552, P = 0. 018) . According to the age, the 1007 patients were divided into 20-39 year group with 242 patients, 40-59 year group with 555 patients, and 60-90 year group with 210 patients, and there was a significant difference in the proportion of patients with an elevated ALT level between these three groups ( 26. 03% vs 8. 83% vs 5. 24%, χ2= 52. 327, P < 0. 001) ; further comparison between any two groups showed that the 20-39 year group had a significantly higher proportion of patients with an elevated ALT level than the 40-59 year group and the 60-90 year group ( χ2= 39. 886 and 34. 009, both P < 0. 001) . Most patients in the elevated ALT group were young and middle-aged adults, and compared with the normal ALT group, the elevated ALT group had a significantly younger age and a significant higher BMI ( t = 7. 419 and-4. 595, both P < 0. 001) ; there were also significant differences between the two groups in UA, number of peripheral blood mononuclear cells, LDL/HDL ratio, HDL, AST, and GGT ( U = 42 942, 47 697, 48 106, 49 086, 31 938, and 36 283, all P < 0. 05) . Of all 1007 patients, 392 had NAFLD complicated by thyroid nodules, and the elevated ALT group had a significantly higher proportion of such patients than the normal ALT group ( 40. 2% vs 30. 1%, P < 0. 05) . The univariate analysis showed that male sex, age ( young and middle ages) , a high number of peripheral blood mononuclear cells, increased LDL/HDL ratio, a low level of HDL, a high level of GGT, a high BMI, and absence of thyroid nodules were associated with elevated ALT in NAFLD patients ( all P < 0. 05) . The multivariate logistic regression analysis showed that young and middle ages ( 20-39 years) , a high number of peripheral blood mononuclear cells, and a high level of GGT were independent risk factors for elevated ALT in NAFLD patients ( all P < 0. 001) . Conclusion Young and middle ages ( 20-39 years) , a high number of peripheral blood mononuclear cells, and a high level of GGT are predictive factors for elevated ALT in NAFLD patients and may have a certain value in guiding the early diagnosis of nonalcoholic steatohepatitis.

2017, 33(12): 2361-2365. DOI: 10.3969/j.issn.1001-5256.2017.12.021
Abstract:

Objective To investigate the correlation of liver fat content ( LFC) with serum vitamin A ( VA) level and insulin resistance ( IR) in patients with nonalcoholic fatty liver disease ( NAFLD) . Methods A total of 200 patients with an initial diagnosis of NAFLD in Shanghai Chongming from February 2016 to January 2017 were enrolled. According to the results of oral glucose tolerance test with 75 g glucose and insulin releasing test, NAFLD patients were divided into simple NAFLD group with 91 patients, NAFLD-impaired glucose regulation ( IGR) group with 69 patients, and NAFLD-type 2 diabetes mellitus ( T2 DM) group with 40 patients. A total of 98 healthy volunteers were enrolled as healthy control group. The homeostasis model was used to evaluate IR, high-performance liquid chromatography was used to measure serum VA level, and 3. 0 T1 H-magnetic resonance spectroscopy was used to measure LFC. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the LSD-t-test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Mann-Whitmey U test was used for further comparison between two groups. The Pearson's chi-squared test was used for comparison of categorical data between groups. A Spearman correlation analysis was also performed. Results There were significant differences in fasting plasma glucose ( FPG) , 2-hour postprandial glucose ( 2 h PG) , and Hb Alc between the healthy control group, simple NAFLD group, NAFLD-IGR group, and NAFLD-T2 DM group ( F = 303. 8, 133. 1, and 249. 3, all P < 0. 01) . The simple NAFLD group, NAFLD-IGR group, and NAFLD-T2 DM group had significant increases in FPG, 2 h PG, and Hb Alc ( all P < 0. 01) , and compared with the simple NAFLD group, NAFLD-IGR group, and NAFLD-T2 DM group, the healthy control group had significant reductions in body mass index, alanine aminotransferase, triglyceride, and low-density lipoprotein ( all P < 0. 01) . The simple NAFLD group, NAFLD-IGR group, and NAFLD-T2 DM group had significantly higher serum VA level, LFC, and HOMA2-IR than the healthy control group ( F = 9. 2, H = 216. 1, and H = 151. 0, all P < 0. 01) . HOMA2-IR and LFC gradually increased in the simple NAFLD group, NAFLD-IGR group, and NAFLD-T2 DM group ( H = 26. 7 and 38. 6, both P < 0. 01) . There were significant differences in HOMA2-IR and LFC between the NAFLD-IGR group and the NAFLD-T2 DM group ( U = 995 and 800, both P < 0. 01) ; there were also significant differences in HOMA2-IR, LFC, and VA between the NAFLD-IGR group and the simple NAFLD group, as well as between the NAFLD-T2 DM group and the simple NAFLD group ( all P < 0. 05) . LFC was positively correlated with VA ( R2= 0. 103, P < 0. 001) and HOMA2-IR ( R2= 0. 531, P < 0. 001) . Conclusion The increase in LFC is closely associated with high serum VA level and disorder of glucose metabolism in patients with NAFLD.

2017, 33(12): 2366-2371. DOI: 10.3969/j.issn.1001-5256.2017.12.022
Abstract:

Objective To investigate the value of transient elastography ( TE) in the diagnosis of nonalcoholic fatty liver disease ( NAFLD) . Methods A total of 21 patients without fatty liver disease and 92 patients with NAFLD, who visited Traditional Chinese Medicine Hospital of Xinjiang Uygur Autonomous Region from June to December, 2016, were enrolled. Their general information was collected and body mass index ( BMI) was calculated. Routine blood test, liver function evaluation, and measurement of blood lipid, serum insulin, and alpha-fetoprotein were performed, and liver CT and Fibro Touch were performed. The receiver operating characteristic ( ROC) curve was plotted with liver/spleen CT ratio as diagnostic criteria, and the ROC curve was used to evaluate the ability of controlled attenuation parameter ( CAP) to diagnose NAFLD. The area under the ROC curve ( AUC) was calculated, the Z test was used to evaluate diagnostic effectiveness, and Youden index was used to determine the optimal cut-off value. The t-test was used for comparison of normally distributed continuous data between two groups; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between any two groups. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between multiple groups. The chi-square test was used for comparison of categorical data between groups. Results There were significant differences in age, alanine aminotransferase ( ALT) , aspartate aminotransferase ( AST) , serum insulin, fat attenuation, and liver stiffness measurement ( LSM) between the patients without fatty liver disease and those with varying degrees of NAFLD ( all P < 0. 05) . The severe NAFLD group had a significantly lower mean age than the non-fatty liver disease group ( P < 0. 001) . There was a significant difference in CAP between the non-fatty liver disease group and the groups with varying degrees of NAFLD ( all P < 0. 001) , while there was no significant difference in CAP between the moderate and severe NAFLD groups ( P = 0. 127) . There was a significant difference in LSM between the non-fatty liver disease group and the moderate NAFLD group ( P = 0. 034) , as well as between the non-fatty liver disease group and the severe NAFLD group ( P < 0. 001) , while there was no significant difference between the moderate and severe NAFLD groups ( P = 0. 327) . There were significant differences in the levels of ALT and AST between the non-fatty liver disease group and the groups with varying degrees of NAFLD ( all P < 0. 001) , and the severe NAFLD group had significantly higher levels of ALT and AST than the mild NAFLD group ( both P =0. 001) . There was a significant difference in the level of insulin between the non-fatty liver disease group and the groups with varying degrees of NAFLD, while there was no significant difference between the groups with varying degrees of NAFLD ( all P > 0. 05) . The optimal cut-off values of CAP for the diagnosis of mild, moderate, and severe NAFLD were 244 d B/m, 272 d B/m, and 272 d B/m, respectively, with AUC of 0. 778 ( 95% confidence interval [CI]: 0. 663-0. 894) , 0. 893 ( 95% CI: 0. 809-0. 976) , and 0. 942 ( 95% CI: 0. 886-0. 998) ( all P < 0. 001) . Conclusion TE is a reliable noninvasiveness method for the diagnosis of NAFLD. CAP can accurately and quantitatively evaluate the degree of NAFLD and effectively differentiate mild NAFLD from moderate or severe NAFLD and thus has a good value in the grading of NAFLD. But it is difficult to differentiate moderate NAFLD from severe NAFLD.

2017, 33(12): 2372-2375. DOI: 10.3969/j.issn.1001-5256.2017.12.023
Abstract:

Objective To investigate the effect of miRNA-384 ( miR-384) expression on hepatic steatosis in mice with nonalcoholic fatty liver disease ( NAFLD) induced by high-fat diet ( HFD) . Methods A total of 30 male C57 BL/6 J mice were fed for 7 days to adapt to the environment and then randomly divided into 2 groups, with 15 mice in each group. The mice in the control group were given normal diet, and those in the model group were given HFD for 8 weeks and then the liver tissue was harvested. HE and Nile red staining were used to observe the pathological changes of the liver. Microarray sequencing was performed to determine the whole-genome miRNA expression profile of liver tissue, and PCR was used to measure the relative expression of miR-384. The t-test was used for the comparison of continuous data between groups. Results In the control group, the liver was red with sharp edges, the lobular structure was clear, and there was no hepatic steatosis; in the model group, the liver was yellow with blunt edges, and the hepatocytes were swollen with a large number of fat vacuoles in the cytoplasm and nuclear deviation caused by the fusion of lipid droplets. Compared with the normal mice, the NAFLD mice had 12 upregulated miRNAs and 18 downregulated miRNAs in liver tissue. Some of the differentially expressed miRNAs between the control group and the model group were screened to obtain the same cluster diagram. Among the 8 miRNAs with significant changes, miR-384 showed a significant fold change. Conclusion The upregulation of miR-384 is closely associated with hepatic steatosis, but its mechanism still needs further study.

2017, 33(12): 2376-2380. DOI: 10.3969/j.issn.1001-5256.2017.12.024
Abstract:

Objective To investigate the prevalence rate of fatty liver disease among people undergoing physical examination in Tangshan, China, and to provide a reasonable basis for the prevention and treatment of fatty liver disease. Methods The clinical data of 12 808 individuals who underwent physical examination in Tangshan from March 2014 to February 2016 were collected, and among these individuals, 3540 had fatty liver disease. The data including age, sex, body mass index ( BMI) , fasting plasma glucose ( FPG) , total cholesterol ( TC) , triglyceride ( TG) , low-density lipoprotein cholesterol ( LDL-C) , and liver ultrasound findings were analyzed. The t-test was used for comparison of continuous data between groups and the chi-square test was used for comparison of categorical data between groups. Results Of all 7151 male individuals who underwent physical examination, 2750 ( 38. 46%) had fatty liver disease, and of all 5657 female individuals, 790 ( 13. 96%) had fatty liver disease; there was a significant difference in the prevalence rate of fatty liver disease between male and female individuals ( χ2= 947. 25, P < 0. 01) . There was a significant difference in the detection rate of fatty liver disease between male and female individuals in each age group of 18-29, 30-39, 40-49, and ≥50 years ( χ2= 337. 58, 474. 06, 449. 38, and 12. 86, all P <0. 01) . There was a significant difference in the detection rate of fatty liver disease between male or female individuals with different BMIs[obese ( BMI ≥28) , overweight ( 24≤BMI < 28) , and normal ( BMI < 24) ] ( χ2= 1104. 01 and 500. 23, both P < 0. 01) . In the three groups of obese ( BMI ≥28) , overweight ( 24≤BMI < 28) , and normal ( BMI < 24) individuals who underwent physical examination, there was a significant difference in the detection rate of fatty liver disease between male and female individuals in each group ( χ2= 71. 24, 87.97, and 323. 84, all P < 0. 01) . Male and female individuals with obesity ( BMI ≥28) and overweight ( 24≤BMI < 28) had a significantly higher detection rate of fatty liver disease than those with normal BMI ( both P < 0. 01) . There were significant differences in FPG, TC, TG, and LDL-C between the fatty liver group and the non-fatty liver group ( t = 17. 482, 13. 698, 22. 133, and 27. 334, all P < 0. 001) . In male individuals who underwent physical examination, there were significant differences in FPG, TC, TG, and LDL-C between the individuals with and without fatty liver disease ( t = 11. 288, 8. 652, 11. 671, and 20. 118, all P < 0. 01) ; in female individuals, there were also significant differences in FPG, TC, TG, and LDL-C between the individuals with and without fatty liver disease ( t = 16. 816, 5. 532, 15. 154, and 18. 507, all P < 0. 01) . Conclusion Among the adults undergoing physical examination in Tangshan, male adults have a significantly higher prevalence rate of fatty liver disease than female adults. Overweight or obesity, hyperlipidemia, and abnormal glucose metabolism are major causes of fatty liver disease.

2017, 33(12): 2381-2383. DOI: 10.3969/j.issn.1001-5256.2017.12.025
Abstract:

Objective To investigate the clinicopathological features of hepatic amyloidosis. Methods A retrospective analysis was performed for 8 patients with hepatic amyloidosis confirmed by liver biopsy in 302 Hospital of PLA from January 2005 to December 2012. Clinical data, laboratory examination results, imaging findings, and pathological data were analyzed to summarize the clinicopathological features of hepatic amyloidosis. Results The clinical manifestations and signs of this disease included hepatomegaly ( 7/8) , weakness ( 6/8) , poor appetite ( 6/8) , splenomegaly ( 4/8) , ascites ( 2/8) , portal hypertension ( 2/8) , edema of lower extremities ( 2/8) , pruritus ( 2/8) , a history of heart disease ( 2/8) , and varices ( 1/8) . Laboratory examination showed increases in alkaline phosphatase ( ALP) ( 8/8) and gamma-glutamyl transpeptidase ( 5/8) , hypoproteinemia ( 2/8) , abnormal alanine aminotransferase ( 2/8) , a slight increase in aspartate aminotransferase ( 1/8) , and abnormal total bilirubin ( 1/8) . As for imaging examinations, ultrasound showed uneven echo of liver parenchyma ( 8/8) ; transient elastography showed a significant increase in liver stiffness ( 2/2) ; CT showed diffuse weakness ( 4/8) or focal weakness ( 2/8) . As for histopathological and immunopathological features, HE staining showed the deposition of pink substances around the hepatic sinusoids ( 8/8) and the central vein ( 6/8) , Congo red staining of the pink substances obtained a positive result ( 8/8) , and the pink substances showed a color of apple green under a polarization microscope; therefore, the patients were diagnosed with amyloidosis. As for immunohistochemistry, of all patients, 6 had positive Kappa staining and 4 had positive Lamda staining. Conclusion Hepatomegaly and elevated ALP are relatively common in patients with primary hepatic amyloidosis. When a patient has hepatomegaly and elevated ALP and cannot be diagnosed with common liver diseases, clinical physicians should consider the possibility of hepatic amyloidosis, which is rare but fatal, and make a confirmed diagnosis based on related examinations, in order to provide guidance for clinical treatment.

2017, 33(12): 2384-2388. DOI: 10.3969/j.issn.1001-5256.2017.12.026
Abstract:

Objective To investigate the effect of retrograde perfusion via the inferior vena cava on renal function in the early stage after liver transplantation. Methods A retrospective analysis was performed for the clinical data of 103 patients with normal serum creatinine and blood urea nitrogen before surgery who underwent liver transplantation in Fuzhou General Hospital from January 2000 to December 2012. According to the surgical approach, these patients were divided into groups A ( orthotopic liver transplantation, 26 patients) and B ( retrograde perfusion via the inferior vena cava, 77 patients) . The two groups were compared in terms of preoperative data [age, sex, primary diseases ( liver cancer/liver cirrhosis) , Model for End-Stage Liver Disease ( MELD) score], time of inferior vena cava occlusion during surgery, intraoperative infusion volume and total volume of blood products, and urine volume, serum creatinine, and blood urea nitrogen at 1-7, 14, and 28 days after surgery. The independent samples t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. Results Compared with group A, group B had a significantly shorter time of inferior vena cava occlusion and significantly lower intraoperative infusion volume and total volume of blood products ( t = 9. 945, 3. 127, and 5. 852, all P < 0. 05) . There was no significant difference in the incidence rate of acute renal failure after surgery between the two groups ( χ2= 1. 920, P > 0. 05) . At 1-2 days after surgery, group A had a significantly higher urine volume than group B ( t = 3. 613 and 2. 929, both P < 0. 05) ; at 2-7, 14, and 28 days after surgery, group B had significantly lower serum creatinine than group A ( t =2. 779, 2. 009, 2. 126, 2. 602, 1. 998, 2. 026, 2. 609, and 3. 870, all P < 0. 05) ; at 1-7, 14, and 28 days after surgery, group B had significantly lower blood urea nitrogen than group A ( t = 5. 895, 3. 212, 1. 830, 2. 348, 3. 030, 3. 549, 2. 287, 2. 996, and 2. 775, all P <0. 05) . Conclusion Retrograde perfusion via the inferior vena cava has little impact on renal function after surgery and brings benefits to the improvement and recovery of renal function after surgery.

Li PingYing, Yang YongGeng, Lu LunGen, Zhu ZhiYong, Wang YaPing, Ma YingCai
2017, 33(12): 2412-2415. DOI: 10.3969/j.issn.1001-5256.2017.12.036
Abstract:
It is very important to find suitable serum markers which can accurately identify chronic hepatitis B ( CHB) -related liver fibrosis. This article summarizes the differentially expressed serum microRNAs ( miRNAs) in the process of CHB-related liver fibrosis. The analysis shows that with the development of liver fibrosis, there are increases in the serum levels of miR-33 a, miR-185, and miR-222 and reductions in the serum levels of miR-122, miR-29, and miR-27 b. It has been found that miRNAs such as miR-185 and miR-122 measured alone or in combination with other indices have a certain clinical value in the diagnosis of CHB-related liver fibrosis. It is pointed out that further research should be conducted for differentially expressed serum miRNAs which have a certain value in the diagnosis of CHB-related liver fibrosis.

2017, 33(12): 2416-2420. DOI: 10.3969/j.issn.1001-5256.2017.12.037
Abstract:
Patients with abnormal renal function complicated by positive HBV serum markers are commonly seen in clinical practice, with a variety of diseases involved, such as patients with nephropathy complicated by HBV infection ( including acute and chronic HBV infection) and those with chronic HBV infection complicated by renal injury ( such as HBV-related nephropathy, hepatorenal syndrome, Fanconi syndrome, and renal injury induced by interferon therapy) . This article elaborates on how to analyze the association between nephrology and HBV infection in clinical practice and points out that clinicians should improve the antiviral therapy for such patients and develop monitoring and management measures.
The role of interleukin-21 in hepatitis B virus infection
Li Yuan, Huang GuYe
2017, 33(12): 2421-2424. DOI: 10.3969/j.issn.1001-5256.2017.12.038
Abstract:
Interleukin-21 ( IL-21) is a cytokine produced by activated CD4+T cells and can affect the function of various lymphocytes. It should be noted that IL-21-mediated cellular and humoral immune responses play an important role in determining the outcome of viral infection. This article introduces the research advances in the important role of IL-21 in hepatitis B virus ( HBV) infection. IL-21 secreted by virus-specific CD4+T cells plays key roles in sustaining CD8+T lymphocyte response and promoting B-lymphocyte response, which is vital for effective viral control. However, as an inflammatory mediator, IL-21 is also involved in the development of hepatitis B-related liver cirrhosis and aggravation of liver injury. Therefore, IL-21 is considered as an immunoregulatory cytokine in HBV infection. Immunotherapeutic strategies aim at optimizing the beneficial effects of IL-21 in HBV infection, which may be a serious challenge in the future.

Feng Gong, Niu ChunYan
2017, 33(12): 2433-2438. DOI: 10.3969/j.issn.1001-5256.2017.12.041
Abstract:
Nonalcoholic fatty liver disease ( NAFLD) has become a major liver disease in the world and its prevalence rate continues to increase. As a component of metabolic syndrome, it has become a risk factor for many serious cerebrovascular and cardiovascular diseases.Due to the complex pathogenesis of NAFLD or the combined/mutual effect of pathogenic factors, there are still no widely accepted effective therapies. In recent years, more and more studies have revealed new pathogeneses of NAFLD and the prospects of corresponding treatment.This article introduces the recent advances in the treatment of NAFLD, including lifestyle intervention, drug therapy, integrated traditional Chinese and Western medicine therapy, and bariatric surgery. In the aspect of drug therapy, this article introduces the drugs commonly used in clinical practice and new drugs in phase II and III clinical trials and their therapeutic effects.
Potential therapeies for nonalcoholic fatty liver disease
Xie Xiao, Lu LunGen
2017, 33(12): 2439-2443. DOI: 10.3969/j.issn.1001-5256.2017.12.042
Abstract:
Nonalcoholic fatty liver disease ( NAFLD) is one of the most common chronic liver diseases in the world, and it is associated with obesity, hyperlipidemia, insulin resistance, and type 2 diabetes. Lipid deposition, insulin resistance, and inflammatory response may induce NAFLD, but detailed mechanism remains unknown. In-depth studies on the pathogenesis of NAFLD have found that macrophage, oxidative stress, and gut microbiota have certain influence on the pathogenesis of NAFLD, and regulation of macrophage polarization and application of carotenoids and anti-tumor necrosis factor may prevent or delay the progression of NAFLD. This article reviews the research advances in potential therapies for NAFLD.
Application of lipid-regulating drugs in prevention and treatment of nonalcoholic fatty liver disease
Lu BingJie, Chen Xi, Sun MingYu
2017, 33(12): 2444-2448. DOI: 10.3969/j.issn.1001-5256.2017.12.043
Abstract:
Nonalcoholic fatty liver disease ( NAFLD) is a clinicopathological syndrome characterized by diffuse macrovesicular steatosis in hepatocytes and is caused by the factors except excessive drinking and other specific factors for liver injury. In particular, lipid metabolism disorder is a significant characteristic of NAFLD, and improvement of dyslipidemia is an important method for the prevention and treatment of NAFLD. Lipid-regulating drugs can not only reduce blood lipids, but also promote the transportation of lipids to the liver for metabolism, which may cause liver lipid accumulation and aggravate liver injury. At present, there are still controversies over the application of lipid-regulating drugs in the treatment of NAFLD in China. Rational use of lipid-regulating drugs has become an important topic in the prevention and treatment of NAFLD. This article summarizes the application of lipid-regulating drugs in NAFLD, in order to provide a reference for lipid-regulating drugs in the prevention and treatment of NAFLD.
Research advances in the mechanism of fructose-induced nonalcoholic fatty liver disease
Chen Ye, Wu JinLu, Pan WenTing, Li HaiYing
2017, 33(12): 2449-2452. DOI: 10.3969/j.issn.1001-5256.2017.12.044
Abstract:
In recent years, the incidence rate of nonalcoholic fatty liver disease ( NAFLD) tends to increase in both developed and developing countries, which is associated with an increase in fructose consumption. This article points out that chronic persistent fructose intake can significantly promote de novo lipogenesis ( DNL) in the liver and induce ATP depletion and inhibition of hepatocyte regeneration, which further causes endoplasmic reticulum stress and increased production of reactive oxygen species in the liver and finally leads to the development of NAFLD. It is believed that detailed mechanism of fructose-induced NAFLD and disruption of fructose metabolism in the liver may provide new therapeutic strategies for NAFLD.

Liu JiaQi, Zhou ShaoMing
2017, 33(12): 2453-2456. DOI: 10.3969/j.issn.1001-5256.2017.12.045
Abstract:
Nonalcoholic fatty liver disease ( NAFLD) is a common chronic liver disease in our country, and its incidence rate is gradually increasing and the age of onset is becoming younger. The pathogenesis of NAFLD remains unclear. Among a variety of pathogenic factors, the change in intestinal flora is closely associated with the development and progression of NAFLD. This article summarizes the mechanism of action of intestinal flora in the development and progression of NAFLD and the treatment of NAFLD by regulating intestinal flora. It is pointed out that regulation of intestinal flora and restoration of intestinal microecological balance may play an important role in delaying or inhibiting the progression of NAFLD and may become a new method for the prevention and treatment of this disease.
Research advances in animal models based on the pathogenesis and treatment of nonalcoholic fatty liver disease
Chen YanZhen, Chen ChengLiang, Tian Xing, Jiao Jian
2017, 33(12): 2457-2461. DOI: 10.3969/j.issn.1001-5256.2017.12.046
Abstract:
Nonalcoholic fatty liver disease ( NAFLD) is a continuous disease spectrum characterized by the accumulation of excessive lipid in hepatocytes. Simple hepatic steatosis may progress to NAFLD and even liver fibrosis, liver cirrhosis, and finally hepatocellular carcinoma.Animal models can simulate different causes and histopathological and pathophysiological changes in each stage of NAFLD and thus provide critical guidance for understanding the pathogenesis of NAFLD and selecting therapeutic measures. At present, there are still no ideal animal models that can simulate the whole disease spectrum. This article introduces the most frequently used and recently developed animal models for NAFLD and NAFLD-induced liver cancer and summarizes possible therapeutic targets with reference to the experimental pathogenesis of NAFLD in animal models, in order to provide a basis for further research on the pathogenesis and treatment of NAFLD.
