BACKGROUND: Chronic liver disease (CLD), mainly non-alcoholic fatty liver disease (NAFLD), is a significant public health concern worldwide. This study aims to quantify the burden of NAFLD in CLD globally and within China, using data from the Global Burden of Disease (GBD) Study 2021, providing crucial insights for global and local health policies. METHODS: The study used comprehensive data from the GBD study 2021. It included estimates of prevalence, incidence, mortality, and disability-adjusted life years (DALYs). Age-standardized rates and average annual percent change (AAPC) from 2011 to 2021 were reported. A meticulous decomposition analysis was conducted. RESULTS: In 2021, there were 1582.5 million prevalent cases, 47.6 million incident cases, 1.4 million deaths, and 44.4 million DALYs attributable to CLD, globally. Among these, NAFLD has emerged as the predominant cause, accounting for 78.0% of all prevalent CLD cases (1234.7 million) and 87.2% of incident cases (41.5 million). Correspondingly, NAFLD had the highest age-standardized prevalence (15,017.5 per 100,000 population) and incidence (876.5 per 100,000 population) rates among CLDs. In addition, China's CLD age-standardized prevalence rate was 21,659.5 per 100,000 population, and the age-standardized incidence rate was 752.6 per 100,000 population, higher than the global average. From 2011 to 2021, the global prevalence rate of CLD increased slowly (AAPC = 0.17), consistent with the trend in China (AAPC = 0.23). Furthermore, the prevalence rate of NAFLD rose significantly in China (AAPC = 1.30) compared with the global average (AAPC = 0.91). Decomposition analysis also showed the worldwide increase in deaths and DALYs for NAFLD, which were primarily attributable to population growth and aging. CONCLUSIONS The burden of CLD and NAFLD remains substantial globally and within China in terms of high prevalence and incidence. As such, this underscores the need for targeted prevention and treatment strategies. These findings emphasize the importance of continued surveillance and research to mitigate the growing impact of liver diseases on global and Chinese health systems.

Objective:To understand the incidence of adverse pregnancy outcome in HIV-infected pregnant women and influencing factors in China and provide reference for the improvement of the health status of HIV-infected pregnant women and their newborns.Methods:Based on a mother-child cohort of HIV-infected pregnant women and children (PMTCT-MC-2005) established in Guangxi Zhuang Autonomous Region, Yunnan Province and Xinjiang Uygur Autonomous Region, this study enrolled pregnant women with or without HIV infection as study subjects from January 2017 to June 2023, a total of 1 646 pregnant women (558 HIV-infected and 1 088 HIV-uninfected) were included, and 34 cases with missing data were excluded. The χ2 test was used to analyze the difference in the incidence adverse pregnancy outcome between two groups, and used logistic regression model to identify the influencing factors of adverse pregnancy outcome in HIV-infected pregnant women. Results:A total of 1 612 pregnant women were included in the study, in whom 541 were infected with HIV and 1 071 were not infected with HIV. The incidence of adverse pregnancy outcome was 18.8% (303/1 612), the incidence of adverse pregnancy outcome was 33.1% (179/541) in the HIV-infected pregnant women and 11.6% (124/1 071) in the pregnant women without HIV infection. The results of multivariable logistic regression analysis showed that the influencing factors of adverse pregnancy outcome were age <35 years at delivery (a OR=0.64, 95% CI: 0.43-0.95) compared with the age ≥35 years and the duration of antiviral treatment over 10 years (a OR=0.43, 95% CI: 0.23-0.79) compared with less than one year. Conclusions:The incidence of adverse pregnancy outcome in HIV-infected pregnant women was high in some regions of China during 2017-2023. It is necessary for HIV-infected women to get pregnancy at appropriate time based on antiretroviral treatment effect and strengthen self-care to reduce the incidence of adverse pregnancy outcome.

Objective:To understand the negative conversion of syphilis-specific antibody in follow-up in 0-18 months-old children born to pregnant women with syphilis in China in 2021 and analyze the related factors.Methods:The basic information of pregnant women with syphilis and follow-up information of their children in 2021 were extracted from the National Management Information System for the Prevention of mother-to-child transmission of HIV, syphilis and Hepatitis B. The logistic regression model was used to analyze related factors of negative conversion of syphilis-specific antibody.Results:In 2021, a total of 34 201 children was delivered by syphilis-infected pregnant women, and 23 592 (68.98%) children were included in this study. Negative conversion of syphilis-specific antibody occurred in 21 076 (89.34%) children, but not in 2 516 (10.66%) children. Multivariate logistic regression analysis identified several factors associated with a higher probability of the negative conversion of syphilis-specific antibody: prophylactic benzathine penicillin injection at birth (a OR=1.35,95% CI:1.10-1.65), mother's age 26-30 years (a OR=1.22,95% CI:1.01-1.46), 36-40 years (a OR=1.34, 95% CI:1.09-1.64), other ethnic groups (a OR=1.19,95% CI:1.04-1.36), non-syphilis-specific antibody titers less than 1∶8 during pregnancy (a OR=1.56,95% CI:1.37-1.78), penicillin treatment (a OR=1.56,95% CI:1.23-1.98) and standardized treatment (a OR=1.21,95% CI:1.11-1.32). Conclusions:In 2021,the level of syphilitic-specific antibody negative conversion in follow-up in children born to pregnant women with syphilis was high in China. According to the factors associated with syphilis-specific antibody negative conversion, it is necessary to develop the follow-up strategies for the children born to pregnant women.

Trauma or surgical intervention in peripheral nerves can lead to traumatic nerve scarring and adhesions, which could hinder nerve regeneration and potentially cause functional impairment. Extensive scarring and adhesions may compress nerves, impair the essential gliding ability and result in fibrosis within the nerves and surrounding tissues. Therefore, searching for effective anti-adhesion strategies to prevent scar formation has become a significant clinical challenge. Currently, the mechanisms underlying the formation of peripheral nerve adhesions are not yet fully understood, and there are limited clinical methods available to prevent the adhesions. This review summarise the preclinical research findings and potential mechanisms of various anti-adhesion strategies, including pharmacological approaches, physical barriers, physical methods, and the combination of them. Additionally, clinical trials and case-control data are evaluated to assess the effectiveness of anti-adhesion strategies that have been applied in clinical settings, providing insights into the potential for future clinical applications of the strategies in prevention of peripheral nerve adhesions.

Objective:To analyze hepatitis B serologic tests and the current prevalence of hepatitis B virus (HBV) infection among pregnant and postpartum women in China from 2021 to 2023.Methods:Data on managing the prevention of mother-to-child transmission of HIV, syphilis, and hepatitis were retrieved from the National Information System. A positive serum HBsAg test was used to define HBV infection. The χ2 test was used to compare the coverage rate of the hepatitis B serologic test across different years, in early-stage pregnancy, and the current HBV infection in pregnant and postpartum women. A two-sided P value of <0.05 was considered a statistically significant difference. Results:The coverage rate for hepatitis B serological detection in pregnant (including intrapartum) and postpartum women and early-stage pregnancy rose from 99.68% (10?463?059/10?496?883) and 82.96% (8?707?765/10?496?883) to 99.94% (8?678?777/8?684?387, P ?
