ObjectiveTo compare the therapeutic effects of carvedilol alone and carvedilol combined with endoscopic variceal ligation （EVL） in the prevention of re-bleeding from gastroesophageal varices， and to provide strategies for clinical treatment. MethodsWe retrospectively included 178 patients who had received carvedilol alone or carvedilol plus EVL to prevent gastroesophageal variceal re-hemorrhage from October 2010 to June 2023. They were divided into carvedilol alone group （47 cases） and carvedilol+EVL group （131 cases）. Between-group comparisons were conducted using the paired t test for normally distributed continuous data， the Mann-Whitney U test for non-normally distributed continuous data， and the chi-square test for categorical data. A Cox proportional hazards model was employed for univariable and multi-variable analyses. The cumulative incidence rates of re-bleeding and mortality were estimated using the Kaplan-Meier method. The baseline characteristics of the two groups were matched through propensity score matching （PSM） to reduce selection bias and enhance the credibility of causal inference. ResultsThe re-bleeding rate of the carvedilol+EVL group was significantly lower than that of the carvedilol alone group （10-year cumulative incidence： 29.8% vs 36.2%， hazard ratio ［HR］=0.505， 95% confidence interval ［CI］： 0.292‍ ‍—‍ ‍0.847， P=0.015）. There was no significant difference in liver-related mortality （10-year cumulative incidence： 21.3% vs 21.4%， HR=0.799， 95%CI： 0.406‍ ‍—‍ ‍1.578， P=0.518）. The results were stable with PSM analysis. The Cox regression analysis revealed that creatinine was an independent risk factor affecting re-bleeding （HR=1.004， 95%CI： 1.001‍ ‍—‍ ‍1.008， P=0.011） and liver-related mortality （HR=1.004， 95%CI： 1.001‍ ‍—‍ ‍1.007， P=0.019）. ConclusionCarvedilol combined with EVL is better than carvedilol alone in the prevention of gastroesophageal variceal re-bleeding.

Asia-Pacific Association for the Study of the Liver published the guidelines on management of ascites in liver disease in May 2023， which introduces the diagnosis， differential diagnosis， and treatment of ascites， hyponatremia， hepatic hydrothorax， and hepatorenal syndrome in patients with liver cirrhosis and acute-on-chronic liver failure. This article summarizes the main recommendations in the guidelines， so as to provide a reference for the treatment of ascites in patients with liver diseases in China.

ObjectiveTo investigate the efficacy of percutaneous transhepatic variceal embolization （PTVE） alone or in combination with partial splenic embolization （PSE） in the treatment of portal hypertensive hemorrhage in liver cirrhosis through a meta-analysis. MethodsThis study was conducted according to PRISMA guideline， with a PROSPERO registration number of CRD42023396690. Wanfang Med Online， CNKI， CBM， VIP Databases， PubMed， Embase， the Cochrane Library， and Web of Science databases were searched for articles on PTVE alone or in combination with PSE in the treatment of portal hypertensive hemorrhage in liver cirrhosis published up to December 23， 2022. The articles were selected based on inclusion and exclusion criteria， and related data were extracted. The RevMan 5.4.1 statistical analysis software was used to perform the meta-analysis. ResultsEight articles were finally included， with a total sample size of 592 cases， among which there were 316 cases in the PTVE+PSE group and 276 cases in the PTVE group. The meta-analysis showed that compared with the PTVE group， the PTVE+PSE group had significantly lower postoperative portal vein pressure （standardized mean difference ［SMD］=-1.75， 95% confidence interval ［CI］： -2.33 to -1.16， P<0.05）， postoperative diameter of the portal vein （SMD=-0.87， 95%CI： -1.64 to -0.10， P<0.05）， postoperative rebleeding rate （odds ratio ［OR］=0.17， 95%CI： 0.11 — 0.28， P<0.05）， mortality rate （OR=0.13， 95%CI： 0.04 — 0.37， P<0.05）， and incidence rate of postoperative portal hypertensive gastrointestinal disease （OR=0.17， 95%CI： 0.07 — 0.45， P<0.05］， as well as a significantly higher postoperative platelet level （SMD=0.79， 95%CI： 0.52 — 1.06， P<0.05）， while there were no significant differences between the two groups in the incidence rates of postoperative ascites. ConclusionCompared with PTVE alone， PTVE combined with PSE can effectively reduce the rebleeding rate and mortality rate of portal hypertensive hemorrhage in liver cirrhosis， the incidence rate of portal hypertensive gastrointestinal disease， and portal vein pressure， and it can also shorten the diameter of the portal vein and increase platelet level. Therefore， it is an effective interventional method for the treatment of portal hypertension hemorrhage in liver cirrhosis.

Cirrhosis is a severe disease caused by chronic inflammatory damage to the liver due to various factors,often complicated by portal hypertension.The primary causes of portal hypertension include increased intrahepatic vascular resistance and increased portal venous blood flow.Carvedilol,a third-generation non-selective beta-blocker(NSBB)with alpha-1 receptor-blocking role,is superior to traditional NSBBs in reducing portal pressure.It is believed that carvedilol significantly reduces hepatic venous pressure gradient(HVPG)through multiple mechanisms,prevents variceal bleeding,and extends patient survival.This paper reviews the mechanisms and clinical applications of carvedilol in the treatment of portal hypertension,focusing on its efficacy in the primary and secondary prevention of varices and its impact on the survival of cirrhotic patients with refractory ascites.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective To investigate the potential causal relationships between coronavirus disease-2019(COVID-19)susceptibility,hospitalization and severe case with late-onset myasthenia gravis(LOMG)based on Mendelian randomization(MR).Methods The public data from non-overlapping genome-wide association studies were screened,COVID-19 susceptibility,hospitalization and severe case served as the exposure data,and LOMG as the outcome data.The inverse-variance weighted(IVW)method was mainly adopted to evalu-ate the causal effect,which was supplemented by the methods such as MR-Egger method,weighted median method,weighted model and simple model.The sensitivity analysis was performed.Results The genetically predicted severe case of COVID-19 had the positively causal relationship with LOMG(OR=1.01,95％CI:1.00-1.03,P=0.046).The sensitivity analysis results revealed the study results were steady(P＞0.05).No heterogeneity or horizontal pleiotropy was found.Conclusion Severe case of COVID-19 may be associated with an increased risk of LOMG.

Objective To evaluate the value of intrathecal synthetic related markers in patients with mild cognitive impairment(MCI),Alzheimer's disease(AD),and other types of dementia.Methods Retrospec-tively collect the clinical data of 577 patients diagnosed with MCI(MCI group,178 cases),AD(AD group,131 cases),and other types of dementia(other types group,268 cases)from June 2019 to July 2023 in Beijing Tiantan Hospital,Capital Medical University.Oligoclonal zone electrophoresis(OCB)and 24 h intrathecal pro-tein synthesis rate(ISR)of each group were investigated,and the difference of different indexes among the groups was compared to evaluate the value of related indexes in the differential diagnosis of different diseases.Results Compared with AD group and other groups,AD group had a higher proportion of females,more patients were＞50-70 years old,and the incidence of abnormal lipid metabolism was higher,with statistical significance(P＜0.05).There were significant differences in OB(S),cerebrospinal fluid albumin,serum albumin and cerebrospinal flu-id IgG in different disease groups(P＜0.05).IgG index and ISR in patients with positive SOB(CSF)were higher than those in negative and weakly positive patients,and the differences were statistically significant(P＜0.001).IgG index was positively correlated with ISR(r=0.878,P＜0.001).Conclusion Intrathecal synthetic mark-ers such as IgG index,SOB(CSF)and 24 h ISR have synergistic effects in the diagnosis of cognitive dysfunction and various dementias,which can be collectively utilized in the diagnosis of diseases.

Objective To analyze the distribution characteristics and application value of liver,renal func-tion indexes and autoantibody-related indexes of neuromyelitis optica spectrum disorder(NMOSD).Methods The liver,renal function and autoantibody-related indexes data of patients diagnosed with NMOSD and multiple sclerosis(MS)in Beijing Tiantan Hospita,Capital Medical University from June 2015 to June 2023,as well as gender and age-matched controls underwent routine physical examination were retrospectively collected.A total of 95 patients with NMOSD(NMOSD group),230 patients with MS(MS group),and 244 healthy controls(routine physical examination group)were selected to evaluate the diagnostic value of each index for NMOSD.Results Compared with MS group,the levels of alanine aminotransferase,as well as the positive rates of α-hydroxybutyrate dehydrogenase,y-glutamyltransferase,anti-SS-A antibody,anti-SS-B anti-body,anti-ribosomal P protein antibody and Ro-52 antibody were significantly increased in NMOSD group,while the levels of albumin,indirect bilirubin and total bilirubin were significantly decreased,and the differ-ences were statistically significant(P＜0.05).The difference index between NMOSD and conventional physi-cal examination group was similar to that of MS group.The seven indexes,a-hydroxybutyrate dehydrogenase,albumin,globulin,direct bilirubin,indirect bilirubin,total bile acid and uric acid alkalinity could be used for the diagnosis of NMOSD.The area under the curve of combined diagnosis of NMOSD was 0.969,and the sensitiv-ity and specificity were 92.6％and 92.9％.Conclusion Multiple indexes of liver and kidney function in NMOSD patients are different from those in MS patients and healthy subjects underwent routine physical ex-amination,and the positive rate of some autoantibody indexes in NMOSD patients is higher than that in MS patients.Liver,renal function and autoantibody-related indexes can be used clinically to assist diagnosis,and the combined application of multiple indexes can further enhance its diagnostic value.
