Objective To investigate the effect of embryonic inflammatory exposure on the response of mouse offspring to interphotoreceptor retinoid-binding protein(IRBP)-induced experimental autoimmune uveitis(EAU).Methods RNA transcriptome sequencing data from eyeballs of C57BL/6J mouse offspring born to mothers with active EAU were used to screen immune-associated differentially expressed genes in the eyes of the exposed offspring.Gene fragments overlapping in the two datasets were screened using Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses to identify biological pathways associated with the gene fragments.Hub genes were identified from these intersecting genes by protein-protein interaction network analysis.EAU models of maternal uveitis were established by immunization with IRBP651-670,and expression levels of the pivotal genes in the offspring exposed to inflammation by maternal uveitis were examined by fluorescence quantitative polymerase chain reaction.EAU severity,T lymphocyte proliferation,and serum cytokines were detected to investigate the immune effect in offspring from mothers with an active inflammation response to IRBP induction.Results Microarray analysis identified 72 immune-related differentially expressed genes in exposed samples compared with the findings in control samples.These genes were mainly enriched in Toll-like receptor signaling,mitogen-activated protein kinase signaling,and B cell receptor signaling pathways.Protein-protein interaction network interaction analysis screened out four hub genes,Psmc5,Psmc3,Psmd4,and Psmd8,and mRNA levels of these four genes were increased in the adult offspring from mothers with active uveitis compared with the findings in healthy offspring.In addition,the group induced with 150 μg IRBP showed an increase in the severity of clinical and pathological outcomes in offspring with EAU affected by active inflammation,compared with the healthy offspring group(P=0.0087,P=0.0410).Meanwhile,T cell proliferation in the offspring was enhanced during the inflammatory activity stage and secretion of the inflammatory cytokines interleukin(IL)-17 and IL-6 was increased(P=0.0450,P=0.0300).Conclusions Psmc5,Psmc3,Psmd4,and Psmd8 may be important genes exacerbating uveitis in offspring of mothers with active uveitis,associated with increased T cell proliferation and production of IL-17 and IL-6.

OBJECTIVES:
The magnesium depletion score (MDS) is considered more reliable than traditional approaches for predicting magnesium deficiency in humans. We explored the associations of MDS and dietary magnesium intake with diabetes.
METHODS:
We obtained data from 18,853 participants in the National Health and Nutrition Examination Survey 2011-2018. Using multivariate regression and stratified analysis, we investigated the relationships of both MDS and magnesium intake with diabetes. To compute prevalence ratios (PRs), we employed modified Poisson or log-binomial regression. We characterized the non-linear association between magnesium intake and diabetes using restricted cubic spline analysis.
RESULTS:
Participants with MDS ≥2 exhibited a PR of 1.26 (95% confidence interval [CI], 1.19 to 1.34) for diabetes. Per-standard deviation (SD) increase in dietary magnesium intake was associated with a lower prevalence of diabetes (PR, 0.91; 95% CI, 0.87 to 0.96). Subgroup analyses revealed a positive association between MDS ≥2 and diabetes across all levels of dietary magnesium intake, including the lowest (PR, 1.35; 95% CI, 1.18 to 1.55), middle (PR, 1.23; 95% CI, 1.12 to 1.35), and highest tertiles (PR, 1.25; 95% CI, 1.13 to 1.37; pinteraction<0.001). Per-SD increase in magnesium intake was associated with lower diabetes prevalence in participants with MDS <2 (PR, 0.92; 95% CI, 0.87 to 0.98) and those with MDS ≥2 (PR, 0.91; 95% CI, 0.84 to 0.98; pinteraction=0.030).
CONCLUSIONS
MDS is associated with diabetes, particularly among individuals with low magnesium intake. Adequate dietary magnesium intake may reduce diabetes risk, especially in those with high MDS.

OBJECTIVES:
Long-term hepatitis B virus (HBV) infection can cause recurrent inflammation in the liver, and then develop into liver fibrosis, cirrhosis, and liver cancer. The hepatic pathological change is one of the important criteria for guiding antiviral therapy in patients with chronic hepatitis B (CHB). Due to the limitations of liver biopsy, it is necessary to find valuable non-invasive indicators to evaluate the hepatic pathological changes in CHB patients and guide the antiviral therapy. This study aims to analyze the clinical characteristics of different pathological changes in CHB patients, and to explore the factors influnencing the degree of liver inflammation and fibrosis in CHB patients with normal alanine aminotransferase (ALT).
METHODS:
This retrospective study was conducted on 310 CHB patients. Liver biopsy was performed in all these patients. The clinical data of the patients were collected. The liver biopsy pathological results were used as the gold standard to analyze the relationship between clinical indicators and liver pathological changes. Then CHB patients with normal ALT were screened, and the independent factors influencing the degree of liver inflammation and fibrosis were explored.
RESULTS:
Among the 310 patients with CHB, there were 249 (80.3%) patients with significant liver inflammation [liver inflammation grade (G) ≥2] and 119 (38.4%) patients with significant liver fibrosis [liver fibrosis stage (S) ≥2]. The results of univariate analysis of total samples showed that the ALT, γ-glutamyl transferase, alkaline phosphatase, and HBV DNA were related to the significant liver pathological changes. Among the 132 CHB patients with normal ALT, the patients with liver pathology G/S≥2, G≥2, and S≥2 were 80.3% (106/132), 68.2% (90/132), and 43.2% (57/132), respectively. The results showed that the independent influencing factor of significant liver inflammation was HBV DNA>2 000 U/mL (OR=3.592, 95% CI 1.534 to 8.409), and the independent influencing factors of significant liver fibrosis were elevated alkaline phosphatase level (OR=1.022, 95% CI 1.002 to 1.043), decreased platelet count (OR=0.990, 95% CI 0.982 to 0.998), and positive in hepatitis B e antigen (HBeAg) (OR=14.845, 95% CI 4.898 to 44.995). According to the multivariate analysis, a diagnostic model for significant liver fibrosis in CHB patients with normal ALT was established, and the area under the receiver operating characteristic curve was 0.844 (95% CI 0.779 to 0.910).
CONCLUSIONS
The liver pathological changes should be evaluated in combination with different clinical indicators. A considerable number of CHB patients with normal ALT still have significant liver pathological changes, which need to be identified and treated with antiviral therapy in time. Among them, HBV DNA>2 000 U/mL suggests the significant liver inflammation, and the diagnostic model for significant liver fibrosis based on alkaline phosphatase, platelet count, and HBeAg can help to evaluate the degree of liver fibrosis.

Chinese Journal of Postgraduates of Medicine 2022;45(3):211-215
Objective:To investigate the correlation between peripheral blood microRNA (miR)-27b expression and left ventricular hypertrophy (LVH) in patients with hypertensive.Methods:The clinical data of 120 patients with hypertension from February 2019 to February 2021 in Zhuzhou Hospital Affiliated to Xiangya School of Medicine, Central South University were retrospectively analyzed. Among them, LVH occurred in 70 cases (LVH group), none in 50 cases (NLVH group). The ventricular septal thickness (VST), left ventricular posterior diastolic wall thickness (LVPWTd) and left ventricular end diastolic diameter (LVEDD) were measured by echocardiography, the left ventricular mass (LVM) and left ventricular mass index (LVMI) were calculated. The peripheral blood expression level of miR-27b was detected by real-time quantitative polymerase chain reaction. Correlation was analyzed by Pearson correlation analysis. Receiver operating characteristic (ROC) curve was drawn to evaluate the efficacy of peripheral blood miR-27b in diagnosing LVH in patients with hypertensive.Results:The peripheral blood expression level of miR-27b in LVH group was significantly higher than that in NLVH group (6.37 ± 0.23 vs. 3.42 ± 0.18), and there was statistical difference ( t = 9.58, P<0.01). Pearson correlation analysis result showed that the peripheral blood expression of miR-27b was positively correlated with LVMI, VST, LVEDD and LVPWTd in hypertensive LVH patients ( r = 0.71, 0.63, 0.75 and 0.68; P<0.01). After eliminating risk factors (duration of hypertension, systolic blood pressure, diastolic blood pressure, different medications, uric acid), multiple linear regression analysis result showed that the peripheral blood expression of miR-27b was positively correlated with LVMI, VST, LVEDD and LVPWTd in hypertensive LVH patients ( β = 0.07, 0.63, 0.42 and 0.48; P<0.01). ROC curve analysis result showed that the area under the curve of peripheral blood expression of miR-27b in predicted LVH in patients with hypertension was 0.905 (95% CI 0.854 to 0.957), the optimal cut-off value was 4.45, the sensitivity was 84.0%, and the specificity was 82.9%. Conclusions:The high peripheral blood expression of miR-27b in hypertension LVH patients is positively correlated with LVMI and other echocardiographic parameters, which has a good predictive value of LVH in patients with hypertension.

Immunosuppressants, which are commonly used for liver transplantation, mainly included calcineurin inhibitors, such as ciclosporin (CsA) and tacrolimus (FK506); glucocorticoid drugs, such as prednisone and prednisolone; cytotoxic drugs, such as azathioprine, mycophenolate mofetil and cyclophosphamide; mammalian target of rapamycin (mTOR) inhibitors, such as sirolimus and everolimus; antibody drugs, such as polyclonal or monoclonal antibodies and interleukin (IL)-2 receptor antibodies, etc. Although many categories of immunosuppressants are available, FK506 is the most commonly adopted in liver transplant recipients. However, FK506 can provoke significant adverse effects in the late stage of liver transplantation, especially severe infection and nephrotoxicity. Consequently, it is an urgent task and research hot spot to develop new immunosuppressants with strong immune tolerance and mild adverse effects in clinical practice. In this article, the research progress on immunosuppressants and the research and development status of new immunosuppressants for liver transplantation were reviewed.
