Clinical features of primary biliary cholangitis and stratified treatment management
Chen Yu, Han Ying
2017, 33(11): 2095-2100. DOI: 10.3969/j.issn.1001-5256.2017.11.009
Abstract:
Primary biliary cholangitis (PBC) is a disease with relatively strong heterogeneity, and different patients may have great differences in clinical process and phenotypes.Therefore, long-term treatment and follow-up are necessary for accurate risk stratification of these patients.Observation of clinical symptoms of PBC patients, measurement of the changes in related indices, and individualized management for each patient helps to provide standard treatment for low-risk PBC patients and bring benefits to high-risk patients through well-designed clinical studies.
Therapeutic strategies for patients with primary biliary cholangitis and suboptimal response to ursodeoxycholic acid
Shi YiWen, You Hong
2017, 33(11): 2101-2104. DOI: 10.3969/j.issn.1001-5256.2017.11.010
Abstract:
In recent years, ursodeoxycholic acid is commonly used for the treatment of primary biliary cholangitis (PBC) ;however, the growing number of PBC patients and the occurrence of suboptimal response and treatment intolerance pose a great challenge to treatment regimens.The approval of the new drug obeticholic acid brings hope to PBC patients, and a combination of fibrates also has a promising future.More studies are in progress.Although new drugs, such as monoclonal antibody, fibroblast growth factor 19, and sodium-dependent bile acid transporter inhibitor, have limited efficacy data, they provide new directions for the treatment of PBC.With the help of individualized follow-up and stratified therapy, the management of PBC patients will enter a new stage.
Advances in genetic research on primary biliary cholangitis
Li YiKang, Ma Xiong, Tang RuQi
2017, 33(11): 2105-2111. DOI: 10.3969/j.issn.1001-5256.2017.11.011
Abstract:
Primary biliary cholangitis (PBC) is an autoimmune liver disease with strong genetic susceptibility.The genome-wide association studies and immunochip studies conducted in recent years help to reveal the pathogenesis of PBC.The susceptibility genes of PBC are classified into human leukocyte antigen gene and non-human leukocyte antigen gene, and most of the susceptibility loci are associated with immune regulation, suggesting that disorders of the immune regulatory pathways may play an important role in the pathogenesis of PBC.In addition, the weighted genetic risk score of these candidate genes may predict the risk of PBC.At present, about one third of PBC patients have suboptimal response to ursodeoxycholic acid;therefore, targeted drugs for susceptibility genes may become an effective substitutive therapy.
Immunological pathogenesis of primary biliary cholangitis
Zhao ZhiBin, Lian ZheXiong
2017, 33(11): 2112-2116. DOI: 10.3969/j.issn.1001-5256.2017.11.012
Abstract:
Primary biliary cholangitis (PBC) is a chronic cholestatic autoimmune disease caused by the attack of the liver by the immune system and is commonly seen in middle-aged women.The pathological features of this disease include the infiltration of a large number of innate immune cells (NK cells, NK T cells, and monocytes, etc.) and adaptive immune cells (T lymphocytes and B lymphocytes) at the portal area and injury of small intrahepatic bile ducts.In addition, PBC patients have high serum levels of anti-mitochondrial antibodies and inflammatory cytokines such as interferon-γ, tumor necrosis factor-α, interleukin-6, and interleukin-12.Although current studies have shown that autoreactive T cells are the major effector cells for PBC, NK cells, NK T cells, monocytes, and B cells around the portal vein also directly or indirectly participate in the development and progression of PBC.This article systematically summarizes the role of innate immune cells, adaptive immune cells, and related chemokines in the pathogenesis of PBC, in order to provide a theoretical basis for a deep understanding of the immunological pathogenesis of PBC.
A study on animal models of primary biliary cholangitis
Hao Juan, Liu ChengHai
2017, 33(11): 2117-2122. DOI: 10.3969/j.issn.1001-5256.2017.11.013
Abstract:
An ideal animal model of primary biliary cholangitis (PBC) plays an important role in the research on physiopathological mechanism and drug research and development.In recent years, great achievements have been made in animal models which can reflect the features of PBC, such as positive serum anti-mitochondrial antibody and immunopathological injury of the bile duct.There are various methods for the preparation of animal models of PBC at present, including chemical or biological exposure and gene knockout.However, these models cannot completely simulate PBC in humans, since they have different serological, immunological, and histopathological features.This suggests the complexity of pathological mechanisms of PBC, including gene specificity and environmental changes and helps us to understand the pathogenesis of events in the early stage of PBC, such as the break of immune tolerance and specific attack of biliary epithelial cells.

Li Wei, Xu KuiHua, Zhao ShouSong
2017, 33(11): 2123-2126. DOI: 10.3969/j.issn.1001-5256.2017.11.014
Abstract:
Objective To investigate the association between liver pathological changes and clinical features in patients with chronic HBV infection and alanine aminotransferase (ALT) 1-2 × upper limits of normal (ULN) .Methods A total of 80 patients with chronic HBV infection and ALT 1-2×ULN who were hospitalized in The First Affiliated Hospital of Bengbu Medical College from July 2015 to December 2016 were enrolled.All patients underwent liver biopsy, and according to positive or negative HBe Ag, these patients were divided into two groups, and the association of liver pathological changes with age, sex, and HBV DNA load was 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 The HBe Ag-negative group had significantly higher age and serum ALT level than the HBe Ag-positive group (t=12.35 and 7.18, both P<0.01) .Compared with the HBe Ag-positive group, the HBe Ag-negative group had a significantly higher proportion of patients with liver inflammation ≥G2 (54.8% vs 76.3%, χ2=53.68, P<0.01) or fibrosis degree ≥S2 (57.1% vs 73.7%, χ2=46.67, P<0.01) .Immunohistochemical staining was performed for 35 patients to measure the expression of HBsAg and HBcAg in the liver, and there were no significant differences in the staining scores of HBsAg and HBcAg between the two groups (both P>0.05) .Conclusion Among patients with chronic HBV infection and slightly elevated ALT, HBe Ag-negative patients have significantly worse conditions of liver lesions than HBe Ag-positive patients.Liver biopsy is recommended for older patients with a long course of disease, in order to provide guidance for antiviral therapy.

Shen GuoJun, Jiang XiaoYun, Huang Jie, Ceng XiaoDong, Mao LongHuo, Fu XiHua
2017, 33(11): 2127-2131. DOI: 10.3969/j.issn.1001-5256.2017.11.015
Abstract:
Objective To investigate the dynamic changes in drug-resistant duck hepatitis B virus (DHBV) DNA in single hepatocyte nucleus after hemihepatectomy using a liver regeneration model.Methods Ducks aged 45 days with chronic DHBV infection were inoculated with mutant DHBV after hemihepatectomy and then fed with lamivudine.Blood samples and liver tissue samples were collected at regular intervals.Viral DNA level in peripheral blood and viral strains were measured.Flow cytometry was used to isolate single hepatocyte nuclei and nuclei with or without proliferating cell nuclear antigen (PCNA) .Nested-PCR was used for the multiplication of intranuclear DHBV YMDD region.Direct sequencing was used to determine the absence or presence of mutation.The chi-square test and the Fisher's exact text were used for comparison of categorical data between groups.The Welch method was used for comparison of PCNA before and after hemihepatectomy.Results There were wild strains in single hepatocyte nuclei and serum before hemihepatectomy.After inoculation with mutant strains, the percentage of hepatocyte nuclei infected with mutant strains decreased significantly from 1 week to 12 weeks after hemihepatectomy (χ2=7.225, P<0.01) .The percentage of PCNA-positive hepatocyte nuclei was 0.84%±0.36% before surgery, significantly increased to42.26%±6.48% at 1 week after surgery, and was 11.83%±3.97% at 12 weeks after surgery, and there was a significant difference between different time points (F=190.832, P<0.001) .The percentage of PCNA-positive nuclei infected with mutant strains decreased significantly from 1 week to 12 weeks after surgery (χ2=7.063, P<0.01) , while the percentage of PCNA-negative nuclei infected with mutant stains was extremely low after surgery.Conclusion Hemihepatectomy may provide a replication space for drug-resistant virus, but drug-resistant virus cannot become dominant strains in the peripheral blood and the liver.

Xu ZhangHong, Jiang KunRen
2017, 33(11): 2136-2140. DOI: 10.3969/j.issn.1001-5256.2017.11.017
Abstract:
Objective To investigate the value of serum neutrophil gelatinase-associated lipocalin (sNGAL) , urinary neutrophil gelatinase-associated lipocalin (uNGAL) , and serum cystatin C (CysC) in the early diagnosis of acute kidney injury (AKI) in patients with liver cirrhosis.Methods A total of 236 patients with liver cirrhosis and normal renal function who visited The Red Cross hospital of Hannan District from January 2015 to March 2017 were enrolled, and according to the presence or absence of AKI within 48 hours after admission, these patients were divided into AKI group with 78 patients and non-AKI group with 158 patients.Another 100 healthy subjects who underwent physical examination were enrolled as control group.ELISA was used to measure sNGAL, uNGAL, and serum CysC, and serum creatinine (SCr) and glomerular filtration rate (GFR) were compared between groups.A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the SNK-q test was used for further comparison between two groups.A Pearson correlation analysis was also performed, and the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of these indices.Results At 48 hours after admission, there were significant differences in sNGAL, uNGAL, and CysC between the AKI group and the non-AKI group/control group (all P<0.05) .The patients in the AKI group were stratified by AKI stage based on the criteria for kidney injury, and the patients with a higher stage had significantly higher levels of sNGAL and uNGAL than those with a lower stage (both P<0.05) .The levels of sNGAL, uNGAL, and CysC started to increase at 6 hours after admission, while Scr and GFR started to change at 48 hours after admission, i.e., sNGAL and uNGAL increased significantly earlier than Scr and GFR (P<0.05) .In the AKI group, sNGAL, uNGAL, and CysC were positively correlated with SCr (r=0.650, 0.681, and 0.581, all P<0.05) .According to the ROC curve analysis, sNGAL had an area under the ROC curve (AUC) of 0.845±0.435, an optimal cut-off value of 542.68 μg/L, a sensitivity of 0.824, and a specificity of 0.794, uNGAL had an AUC of 0.836±0.326, an optimal cut-off value of 75.12 μg/L, a sensitivity of 0.816, and a specificity of 0.766, and CysC had an AUC of 0.818±0.267, an optimal cut-off value of 1.48 mg/L, a sensitivity of 0.808, and a specificity of 0.732.Conclusion NGAL and CysC can be used as indices for the early diagnosis of AKI and have great significance in evaluating renal injury and developing treatment measures for patients with liver cirrhosis.

Lu Hao, Xu XiaoYa, Ye JinDong, Guo Dong, Duan LiuXin, Li ZhangZheng, Liu QuanDa
2017, 33(11): 2141-2146. DOI: 10.3969/j.issn.1001-5256.2017.11.018
Abstract:

Objective To investigate the clinical effect of modified splenic artery embolization of the splenic artery and branch arteries in the treatment of splenic artery steal syndrome (SASS) and hypersplenism due to liver cirrhosis, since in patients with liver cirrhosis complicated by hypersplenism, the enlarged splenic artery competitively“steals”the blood flow in the celiac trunk and causes hypoperfusion in the hepatic artery (i.e., SASS due to liver cirrhosis) .Methods A total of 220 cirrhotic patients with hypersplenism and SASS who were hospitalized in General Hospital of the PLA Rocket Force and Chinese PLA General Hospital from January 2007 to December 2015 were enrolled and divided into medical treatment group with 120 patients (drugs combined with endoscopic intervention) , partial splenic embolization (PSE) with 40 patients (PSE combined with medical treatment) , and modified splenic artery embolization (MSAE) group with 60 patients (embolization of the splenic artery and branch arteries combined with medical treatment) .Related indices were analyzed and compared between the three groups.A one-way analysis of variance was used for comparison of continuous data between three groups, and the least significant difference t-test was used for further comparison between two groups;the chi-square test was used for comparison of categorical data between groups;the Kaplan-Meier survival analysis was used to calculate survival rates and gastrointestinal bleeding rate;the log-rank test was used to evaluate statistical difference.Results Within 5 years after surgery, the MSAE group had significantly higher platelet and leukocyte counts than the medical treatment group (P<0.05) .At 6 months after surgery, the MSAE group had a significantly lower Child-Pugh score than the medical treatment group (P<0.001) and the PSE group (P=0.014) ;at 1 year after surgery, the MSAE group still had a significantly lower Child-Pugh score than the medical treatment group (P=0.009) .At 6 months after surgery, the MSAE group had a significantly lower Model for End-Stage Liver Disease (MELD) score than the medical treatment group (P=0.004) and the PSE group (P=0.048) ;at 1 year after surgery, the MSAE group still had a significantly lower MELD score than the medical treatment group (P=0.012) .The MSAE group had significantly lower numbers of gastrointestinal bleeding/rebleeding events and endoscopic therapies than the PSE group (χ2=9.41, P=0.009) and the medical treatment group (χ2=10.91, P=0.004) ;at 5 years after surgery, the MSAE group still had a significantly lower incidence rate of gastrointestinal bleeding/rebleeding than the medical treatment group (χ2=14.70, P=0.002) .The MSAE group had certain improvements in the degree and duration of postoperative complications (pyrexia and abdominal pain) and had a lower incidence rate of serious complications (splenic abscess) , as compared with the other two groups.The median survival time was 45 (8-91) months in the MSAE group, 41 (6-86) months in the PSE group, and 34.5 (7-84) months in the medical treatment group.During the 5-year follow-up, 7 patients (11.7%) in the MSAE group, 40 (30%) in the medical treatment group, and 7 (17.5%) in the PSE group died.The MSAE group had a significantly higher cumulative survival rate than the medical treatment group (χ2=9.733, P=0.001) .Conclusion Modified splenic artery embolization of the splenic artery and branch arteries has good safety and can effectively correct hypersplenism and SASS due to liver cirrhosis, improve liver function, and reduce the risk of gastrointestinal bleeding.Therefore, it deserves further investigation.

2017, 33(11): 2147-2151. DOI: 10.3969/j.issn.1001-5256.2017.11.019
Abstract:
Objective To investigate the risk factors for early rebleeding after esophageal variceal ligation (EVL) in patients with liver cirrhosis.Methods A retrospective analysis was performed for the clinical data of 506 cirrhotic patients with esophageal varices who were admitted to Shaanxi Provincial People's Hospital from January 2000 to May 2016 and underwent EVL, and according to the presence or absence of early rebleeding after surgery, these patients were divided into bleeding group with 38 patients and non-bleeding group with 468 patients.The factors that could lead to postoperative rebleeding were collected.The t-test was used for comparison of normally distributed continuous data between groups, and the chi-square test was used for comparison of categorical data.An unconditional multivariate logistic regression analysis was used to investigate independent risk factors.Results The univariate analysis showed that there were significant differences between the two groups in sex (χ2=5.675) , number of times of hematemesis before treatment (t=1.335) , amount of hematemesis before treatment (χ2=1.983) , number of times of melena (t=2.984) , number of varicose veins (t=1.083) , serum prothrombin time (t=2.182) , prothrombin time activity (t=2.584) , albumin (Alb) (t=1.046) , total bilirubin (t=2.463) , aspartate transaminase (t=3.473) , severity of ascites (χ2=8.484) , Child-Pugh score (t=1.664) , Child-Pugh class (χ2=15.675) , number of ligation points (t=1.134) , and number of times of ligation (t=3.902) (all P<0.05) .The multivariate logistic regression analysis showed that male sex (odds ratio [OR]=1.598, 95% confidence interval [CI]:1.038-2.929) , Child-Pugh score>7.2 (OR=2.306, 95% CI:1.443-3.031) , and small, moderate, and large amounts of hematemesis before treatment (OR=1.342, 2.763, and 4.675, 95% CI:1.014-2.627, 1.356-4.122, and 2.321-6.929) were independent risk factors for early rebleeding after EVL (all P<0.05) , while Alb>31.5 g/L was a protective factor against early rebleeding after EVL (OR=0.411, 95% CI:0.288-0.641, P<0.05) .Conclusion Health education should be enhanced for male patients after EVL, and early correction of liver function and coagulation disorders, improvement of Alb level, prevention and treatment of ascites, and improvement in technical level of ligation may help to reduce the incidence rate of early rebleeding after EVL.

2017, 33(11): 2179-2185. DOI: 10.3969/j.issn.1001-5256.2017.11.026
Abstract:

Objective To investigate the clinical and pathological features of autoimmune hepatitis (AIH) -primary biliary cholangitis (PBC) overlap syndrome (AIH-PBC OS) versus AIH, since it is still difficult to diagnose AIH-PBC OS in clinical practice, and to enhance the knowledge of AIH-PBC OS and improve its early diagnostic rate.Methods A prospective study was performed for the clinical data, biochemical and immunological markers, autoantibody, and liver pathology of 50 patients with AIH-PBC OS confirmed by liver biopsy who visited West China Hospital, Sichuan University, from January 20, 2015 to November 28, 2016 and 57 patients with AIH alone, in order to compare the features of AIH-PBC OS and AIH.Continuous data such as laboratory markers were expressed as median M (inter-quartile range) and the nonparametric rank sum test was used for comparison of these data between two groups;categorical data including clinical features、histopathological manifestations were expressed as rates and the chi-square test was used for comparison of these data between two groups.Results The AIH-PBC OS group had a significantly lower age of onset than the AIH group (Z=-1.975, P=0.048) , while there was no significant difference in male/female sex ratio between the two groups.The AIH-PBC OS group had a significantly higher proportion of patients with pruritus than the AIH group (22.0% vs 7.0%, χ2=4.960, P=0.026) .Compared with the AIH group, the AIH-PBC OS group had significantly higher levels of alkaline phosphatase (ALP) , gamma-glutamyl transpeptidase (GGT) , and immunoglobulin M (IgM) (Z=-6.250, -4.789, and-5.407, all P<0.001) , a significantly higher positive rate of antimitochondrial antibody (AMA) (χ2=26.811, P<0.001) , and significantly lower serum levels of alanine aminotransferase (ALT) , aspartate aminotransferase, and immunoglobulin G (IgG) (Z=-2.916, -3.381, and-2.285, P=0.004, 0.001, and 0.022) .The AIH-PBC OS group had significantly higher incidence rates of bile duct injury, bile duct loss, granulomatous disease, and cholestasis than the AIH group (χ2=25.612, 15.953, 6.490, and 10.042, P<0.001, <0.001, 0.001, and 0.002) .Conclusion Although AIH-PBC OS has the features of both AIH and PBC, it is not a simple overlap between AIH and PBC.Pruritus, significant increases in the levels of ALP, GGT, and IgM, positive AMA, and inflammatory bile duct disease and cholestasis may have implications for the diagnos of AIH-PBC OS.Since AIH-PBC OS may have milder liver inflammatory injury and autoimmune abnormalities than AIH, the levels of ALT and IgG in Paris criteria can be broadened during the diagnosis of AIH-PBC OS, in order to prevent missed diagnosis and avoid affecting the selection of treatment regimen and patients' prognosis.

Abstract:
Hepatic fibrosis is the common pathological basis of various chronic liver diseases.Liver biopsy remains the gold standard for the assessment and diagnosis of liver fibrosis, but its invasiveness and high requirements for operation limit its clinical application.This article introduces the development of noninvasive diagnosis of hepatic fibrosis, such as serological and imaging techniques.However, these methods cannot completely replace liver biopsy.Therefore, a comprehensive noninvasive diagnosis model for hepatic fibrosis has become a research hotspot.
Application of non-selective β-blockers in patients with liver cirrhosis
Liu XiaoYan, Su HaiBin
2017, 33(11): 2214-2217. DOI: 10.3969/j.issn.1001-5256.2017.11.036
Abstract:
Non-selective β-blockers (NSBBs) can effectively reduce hepatic venous pressure gradient (HVPG) , and are the first-line drugs for primary and secondary prevention of liver cirrhosis complicated by esophagogastric variceal bleeding.In addition, NSBBs can alleviate inflammatory response in patients with severe liver diseases.However, there are still controversies over the use of NSBBs in patients with liver cirrhosis complicated by intractable ascites, primary bacterial peritonitis, or kidney dysfunction.Therefore, NSBBs have a window period in the prevention of esophageal variceal bleeding with varying doses.Moreover, NSBBs have cardiogenic or non-cardiogenic side-effects, and thus side-effects should be closely monitored and the dose should be adjusted.This article reviews the latest research advances in NSBBs in preventing esophagogastric variceal bleeding.
Pathogenesis of portal hypertensive gastropathy in cirrhotic patients and the application of antacids in treatment
Yang ZongGuo, Zhang JianLiang
2017, 33(11): 2218-2221. DOI: 10.3969/j.issn.1001-5256.2017.11.037
Abstract:
Portal hypertensive gastropathy (PHG) has a high incidence rate in cirrhotic patients, leading to a high risk of upper gastrointestinal bleeding.Gastric mucosal injury is the major pathological change of PHG.There are few studies focusing on the clinical application of antacids in the treatment of PHG in cirrhotic patients and there are still controversies over this issue.This article reviews the influencing factors for PHG, the mechanism of gastric mucosal injury, and the application of antacids.It is pointed out that during the treatment of PHG, besides the reduction in portal venous pressure, the application of antacids such as proton pump inhibitors can improve the cure rate of PHG.Prospective randomized control trials with a large sample size are needed to further demonstrate the clinical effect and safety of antacids in the treatment of PHG in cirrhotic patients.

2017, 33(11): 2226-2229. DOI: 10.3969/j.issn.1001-5256.2017.11.039
Abstract:
Osteoporosis is a common complication of primary biliary cholangitis (PBC) with a relatively high prevalence rate and a high risk of bone fracture.The pathogenesis of osteoporosis remains unknown.This article reviews the latest advances in the pathogenesis and treatment of osteoporosis in PBC.Studies have shown that osteoporosis in PBC has various causes, including increased bone absorption and reduced bone formation due to many factors.Although many drugs have been used in clinical practice, until now, bisphosphonates are still the most effective drugs.Long-term systematic studies are needed in the future to clarify their effects on fracture in PBC patients.
New advances in the treatment of refractory primary biliary cholangitis
Ni Ping, Fan XiaoLi, Wen MaoYao, Yang Li
2017, 33(11): 2230-2234. DOI: 10.3969/j.issn.1001-5256.2017.11.040
Abstract:
Primary biliary cholangitis (PBC) is an autoimmune liver disease characterized by small bile duct injury.Ursodeoxycholic acid (UDCA) is often used for the treatment of this disease;however, about 40% of PBC patients do not respond adequately to UDCA and often have poor prognosis.This article summarizes the new therapeutic options for such patients.In 2017, obeticholic acid has been recommended as the second-line therapeutic drug for PBC patients with suboptimal response to UDCA by European Association for the Study of the Liver.Some achievements have been made in the research on fibrates and budesonide administered alone or in combination for the treatment of refractory PBC, but their efficacy and safety need to be further confirmed by large-sample, double-blind, randomized controlled trials.Monoclonal antibody, change in the production of bile acid, and drug reabsorption are still under experiment.At present, liver transplantation remains the only therapeutic method for patients with end-stage PBC.

2017, 33(11): 2235-2238. DOI: 10.3969/j.issn.1001-5256.2017.11.041
Abstract:
Primary biliary cholangitis (PBC) is an autoimmune disease characterized by the destruction of interlobular bile ducts and infiltration of inflammatory factors.An increase in anti-mitochondrial antibody is the major feature of PBC and may eventually lead to intrahepatic cholestasis, liver fibrosis, and even liver cirrhosis.The pathogenesis of this disease remains unclear, and there is no ideal treatment regimen.Therefore, it is necessary to find an animal model matching with PBC, in order to study the pathogenesis, treatment, and prognosis of PBC.This article introduces the research advances in bile duct ligation models, drug models, antigen models, gene models, and spontaneous models, in order to summarize the features and limitations of the mouse model of PBC in the articles published in recent years and provide a basis for the selection and research of PBC models.

Lin Yan, Li Xun
2017, 33(11): 2243-2246. DOI: 10.3969/j.issn.1001-5256.2017.11.043
Abstract:
Chronic liver diseases such as liver fibrosis and liver cirrhosis have a complex pathogenesis and are the result of interaction between various cells, cytokines, and matrix in the liver.The traditional viewpoints believe that platelets are mainly involved in hemostasis and coagulation.In recent years, more and more articles have reported that platelets contain molecular protein for hemostasis and growth factors for organ development and tissue regeneration/repair;moreover, platelets are closely associated with the development and progression of chronic liver diseases such as liver fibrosis and liver cirrhosis and regeneration of liver tissue.They also play a key role in liver homeostasis and pathology.At present, many research findings have been achieved in the association between platelets and the signaling pathways of liver fibrosis and liver regeneration, suggesting that platelets may become a new target for the treatment of chronic liver diseases.

2017, 33(11): 2251-2255. DOI: 10.3969/j.issn.1001-5256.2017.11.045
Abstract:
Locally advanced pancreatic cancer has a poor prognosis, and conventional radiotherapy alone or combined with chemotherapy has limited effects on local control of locally advanced pancreatic cancer and survival benefit for such patients.Stereotactic radiotherapy and intensity-modulated radiotherapy can control local tumor progression and improve patients' quality of life with few adverse effects and have gradually been used in the treatment of locally advanced pancreatic cancer in recent years.Rapid development of drugs inhibiting DNA repair and extensive research on DNA repair inhibitors at the molecular, cellular, and animal levels and their preliminary clinical application can effectively improve the prognosis of locally advanced pancreatic cancer.
