Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

Methods: Data of viral hepatitis cases in Yuxi City from 2004 to 2022 were retrieved from the China Disease Prevention and Control Information System. The temporal, human and spatial distribution of viral hepatitis cases were analyzed using a descriptive epidemiological method, and the trends in incidence of viral hepatitis were evaluated in Yuxi City from 2004 to 2022 using annual percent change (APC) and average APC (AAPC). Results: A total of 37 430 viral hepatitis cases were reported in Yuxi City from 2004 to 2022, with an average annual incidence rate of 91.27/105, and the incidence showed a tendency towards a rise (AAPC=12.686, P<0.05). There were 29 229 cases with hepatitis B, 5 796 cases with hepatitis C, 1 451 cases with hepatitis A, 520 cases with hepatitis E and 434 cases with unclassified hepatitis reported in Yuxi City, with average annual incidence rates of 71.27/105, 14.13/105, 3.54/105, 1.27/105 and 1.06/105, respectively. The average annual incidence rates of viral hepatitis were 98.24/105 and 78.94/105 among men and women, which both appeared a tendency towards a rise (AAPC=12.415% and 12.581%, both P<0.05). The highest average annual incidence of viral hepatitis was seen among residents at age of 25 to 29 years (139.89/105), with the lowest seen among residents at ages of 0 to 4 years (11.38/105), and the average annual incidence of viral hepatitis appeared a tendency towards a rise with age (P<0.05). The highest average annual incidence of viral hepatitis was seen in Huaning County (234.24/105), with the lowest seen in Chengjiang City (26.11/105), and the average annual incidence appeared a tendency towards a rise in Xinping County from 2004 to 2022 (AAPC=21.451%, P<0.05). Conclusions The reported incidence of viral hepatitis appeared a tendency towards a rise in Yuxi City from 2004 to 2022, with hepatitis B as the main type. High incidence was seen among men and adolescents. The viral hepatitis control strategy requires to be adjusted with adaptations to high-incidence hepatitis subgroups, residents and regions.

Diabetes mellitus is one of the most common complications after liver transplantation. The survival rate of recipients after liver transplantation with diabetes mellitus and the long-term survival rate of grafts are significantly lower than those of their counterparts without diabetes mellitus. In recent years, diabetes mellitus after liver transplantation has attracted widespread attention along with the rapid development of liver transplantation in China. Although post-transplantation diabetes mellitus (PTDM) has been extensively investigated in the past two decades, multiple problems remain to be further resolved. The study was designed to review the latest research progress upon diabetes mellitus after liver transplantation, covering the definition and diagnostic criteria of PTDM, risk factors, prevention and treatment of diabetes mellitus after liver transplantation, aiming to deepen the understanding of diabetes mellitus following liver transplantation, deliver effective prevention and management, improve the long-term survival rate and enhance the quality of life of the recipients.

Objective To determine the impact of uric acid changes on kidney function in middle-aged and elderly women with normal renal function.Methods Serum uric acid and estimated glomerular filtration rate(eGFR) were studied by prospective cohort analysis in 1152 middle-aged and elderly Dalian women with serum uric acid<7 mg/dl, estimated glomerular filtration rate(eGFR)≥90 ml·min-1·(1.73 m2)-1, and age>45 years old.Results The analysis of variance (ANOVA) of clinical indices between baseline and follow-up data showed that an eGFR was decreased after three years in both middle-aged and elderly women even with normal serum uric acid.Compared with those in the lowest guartile subgroup, a significant drop of eGFR to less than 90 ml·min-1·(1.73 m2)-1 was seen in those with the highest guartile of baseline serum uric acid group (OR=1.707, 95%CI 1.192-2.443, P=0.003).Furthermore, there were positive correlations between changes in the levels of serum uric acid and eGFR, and linear regression analysis showed that, as the change level of serum uric acid increased, the change level of eGFR declined(β=1.562, 95%CI 1.050-2.075, P<0.01], and the changing degree of uric acid increase is independent risk factors refor eGFR reductions.Conclusion Reduction in eGFR level is inversely related to serum uric acid in perimenopausal and postmenopausal women.However, our study showed that, women with serum uric acid level ranging from normal, slight increase, and relatively high levels, the increasing degrees of uric acid are independent risk factors responsible for the changing degree of eGFR reduction.

Objective To investigate the effect and mechanism of liver X receptor ( LXR ) agonist on expression of fatty acid synthase( FAS) in diabetic kidney. Methods In the part of in vivo study, immunostaining was used to detect the FAS protein expression in kidney. 16-week-old male db/db mice on C57BL/6 background were administered via gavage a LXR synthetic agonist, TO901317, at a dose of 3 mg · kg-1 · d-1 or vehicle ( 0. 5%Carboxymethyl Cellulose Sodium, CMC-Na) alone for 7 d;Quantitative RT-PCR and Western blot were used to detect mRNA and protein levels of FAS and SREBP-1. In the part of in vitro study, MCT cell(a mouse murine proximal tubule cell line)was treated with 10μmol/L TO901317 for 24 h or transfected with active SREBP-1c expression vector (SREBP-1cN). HEK293 cells(a human renal tubule cell line)were transfected with mFAS-(1. 7 kb)-luc, LXR expression vector or SREBP-1cN for 12 h. Quantitative RT-PCR and luciferase reproter assay were utilized to examine FAS mRNA level and FAS promoter activity. Results FAS was abundantly expressed in renal cortex, with low expresson in renal glomeruli. The mRNA and protein expressious of FAS in kidney of db/db mice were lowered compared with db/m mice. TO90137 treatment increased FAS mRNA expression by 1. 3-fold. TO901317 increased expression of SREBP-1 in kidneys of db/m and db/db mice by 5. 1-fold and 17-fold, respectively. TO901317 and overexpression of SREBP-1c increased expression of FAS in MCT cells by 1. 5-fold and 1. 8-fold. Transcription activity of FAS were induced by TO901317, LXR, and SREBP-1cN overexpressions in HEK293 cells. Conclusions Both direct(LXRE)and indirect(SREBP-1c)mechanisms may contribute to the up-regulation of FAS expression by LXR in renal proximal tubule cells.
