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 explore whether tryptophan metabolism is related to bone growth by comparing the differences in tryptophan metabolism after rotator cuff tear (RCT) repair between rats with normal bone remodeling capability and those with defective bone remodeling capability.Methods:Of the 50 adult female Sprague Dawley (SD) rats used for this study, 18 were randomly selected to undergo bilateral ovariectomy (OVX) (OVX group), and the remaining 32 underwent bilateral OVX sham surgery (sham surgery group). All rats were maintained in standard conditions. Three months after surgery, 4 rats were randomly selected from OVX group and the sham surgery group, respectively, for Micro CT identification of bone loss at the rat humeral head. The remaining rats in OVX group underwent RCT modeling and surgical repair of acute supraspinatus muscle transection (OVX+RCT group) ( n=14); the remaining rats in the sham surgery group were subjected to either surgical repair of acute supraspinatus muscle transection (RCT group, n=14) or RCT sham surgery (SO group, n=14). The grip power of the rats was tested 2 weeks after surgery. The supraspinatus tendon-bone complex was harvested for evaluation of new bone formation and growth through real-time fluorescence quantitative polymerase chain reaction (qPCR), hematoxylin eosin (HE) staining, and immunohistochemistry (IHC) staining. The tryptophan metabolism was analyzed using ultra high performance liquid chromatography (UPLC). Results:The grip power test showed that SO group had the greatest grip power, followed by RCT group and OVX+RCT group, with statistically significant differences between the 3 groups ( P<0.05). The qPCR showed that the relative expression of osteosclerosis in the tendon-bone complex in SO group was significantly higher than that in OVX+RCT group and RCT group; IHC staining showed that the relative expression of osteocalcin in RCT group was significantly higher than that in SO group and OVX+RCT group ( P<0.05). The UPLC showed that the content of tryptophan in the rotator cuff tendon-bone complex was similar among SO, RCT, and OVX+RCT groups, showing no significant difference ( P>0.05). The qPCR showed that the expression of indoleamine 2, 3-dioxygenase 2 in the Kynurenic acid metabolism pathway showed an increasing trend from SO group to RCT group to OVX+RCT group, with OVX+RCT group significantly higher than SO group ( P<0.05). The expression of 3-hydroxybenzoate 3, 4-dioxygenase in OVX+RCT group was significantly higher than that in RCT group and in SO group ( P<0.001). The subtypes A and B of monoamine oxidase in the 5-hydroxytryptamine metabolism pathway increased from SO group to RCT group to OVX+RCT group. The subtypes A and B of monoamine oxidase in the 5-hydroxytryptamine metabolism pathway increased among SO, RCT, and OVX+RCT groups( P<0.001). The expression of dopamine decarboxylase in the indole metabolism pathway in OVX+RCT group was significantly higher than that in SO group ( P<0.01). The expression of cytochrome P450 oxidoreductase increased from SO group to RCT group to OVX+RCT group ( P<0.001). Conclusions:The tryptophan metabolism in the supraspinatus tendon-bone complex after RCT in rats is mainly dominated by kynurenic acid metabolism, followed by 5-hydroxytryptamine metabolism. In RCT bone remodeling, the 5-hydroxytryptamine metabolic pathway changes the most, followed by the indole pathway. The contents of niacin and xanthurenic acid in the kynurenic acid metabolism pathway are related to bone growth; the 5-hydroxytryptamine, hydroxyindoleacetic acid, and melatonin in the 5-hydroxytryptophan metabolic pathway are related to bone growth; the tryptophan and indole lactate in the indole metabolism pathway are related to bone growth. Therefore, tryptophan metabolism is related to bone growth, providing potential therapeutic targets for RCT repair.
