Objective To investigate the relationship between interleukin-1β (IL-1β) and miR-185-5p in the process of joint injury in acute gouty arthritis (AGA). Methods The serum miR-185-5p levels of 89 AGA patients and 91 healthy volunteers were detected by real-time quantitative PCR. The correlation between miR-185-5p expression level and VAS score or IL-1β expression level was evaluated by Pearson correlation coefficient method. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of miR-185-5p in AGA. THP-1 cells were induced by sodium urate (MSU) to construct an in vitro acute gouty inflammatory cell model. After the expression level of miR-185-5p in THP-1 cells was upregulated or downregulated by transfection of miR-185-5p mimics or inhibitors in vitro, inflammatory cytokines of THP-1 cells, such as IL-1β, IL-8 and tumor necrosis factor α (TNF-α), were detected by ELISA. The luciferase reporter gene assay was used to determine the interaction between miR-185-5p and the 3'-UTR of IL-1β. Results Compared with the healthy control group, the expression level of serum miR-185-5p in AGA patients was significantly reduced. The level of serum miR-185-5p was negatively correlated with VAS score and IL-1β expression level. The area under the curve (AUC) was 0.905, the sensitivity was 80.17% and the specificity was 83.52%. Down-regulation of miR-185-5p significantly promoted the expression of IL-1β, IL-8 and tumor necrosis factor (TNF-α), while overexpression of miR-185-5p showed the opposite results. Luciferase reporter gene assay showed that IL-1β was the target gene of miR-185-5p, and miR-185-5p negatively regulated the expression of IL-1β. Conclusion miR-185-5p alleviates the inflammatory response in AGA by inhibiting IL-1β.

Objective:To examine the associations of BMI and waist circumference (WC) with the risk of chronic kidney disease (CKD) and its subtypes in adults in China.Methods:The data from the China Kadoorie Biobank were used. After excluding those with cancer, coronary heart disease, stroke, or CKD at baseline survey, 480 430 participants were included in this study. Their body height and weight, and WC were measured at baseline survey. Total CKD was defined as diabetic kidney disease (DKD), hypertensive nephropathy (HTN), glomerulonephritis (GN), chronic tubulointerstitial nephritis (CTIN), obstructive nephropathy (ON), CKD due to other causes, and chronic kidney failure. Cox proportional hazards regression model was used to estimate the associations between exposure factors and risks of outcomes.Results:During a follow-up period of (11.8±2.2) years, 5 486 cases of total CKD were identified, including 1 147 cases of DKD, 340 cases of HTN, 1 458 cases of GN, 460 cases of CTIN, 598 cases of ON, 418 cases of CKD due to other causes, and 1 065 cases of chronic kidney failure. After adjusting for socio-demographic factors, lifestyle factors, baseline prevalence of hypertension and diabetes, and WC and compared to participants with normal BMI (18.5-23.9 kg/m 2), the hazard ratios ( HRs) of total CKD for underweight (<18.5 kg/m 2), overweight (24.0-27.9 kg/m 2), and obese (≥28.0 kg/m 2) were 1.42 (95% CI: 1.23-1.63), 1.00 (95% CI: 0.93-1.08) and 0.98 (95% CI: 0.87-1.10), respectively. Stratification analysis by WC showed that BMI was negatively associated with risk for total CKD in non-central obese participants (WC: <85.0 cm in men and <80.0 cm in women) ( HR=0.97, 95% CI: 0.96-0.99), while the association was positive in central obese participants (≥90.0 cm in men and ≥85.0 cm in women) ( HR=1.03, 95% CI: 1.01-1.05). The association between BMI and GN was similar to that of total CKD. BMI was associated with an increased risk for HTN, with a HR of 1.12 (95% CI: 1.06-1.18) per 1.0 kg/m 2 higher BMI. After adjusting for potential confounders and BMI, compared to participants with non-central obesity, the HRs for pre-central obesity (WC: 85.0-89.9 cm in men and 80.0-84.9 in women) and central obesity were 1.26 (95% CI: 1.16-1.36) and 1.32 (95% CI: 1.20-1.45), respectively. With the exception of HTN and CTIN, WC was positively associated with risks for all CKD subtypes. Conclusions:BMI-defined underweight and central obesity were independent risk factors for total CKD, and BMI and WC had different associations with risks for disease subtypes.

ObjectiveTo investigate the relationship between serum 25(OH)D and gestational diabetes mellitus in the second trimester (GDM), to analyze the interaction effect of key risk factors, so as to provide a basis for clinical personalized vitamin D supplementation. MethodsA total of 266 pregnant women who registered and took regular obstetric check-ups in Shanghai Pudong New Area Health Care Hospital for Women and Children from June to December 2022, were selected as the research subjects. According to the results of oral glucose tolerance test (OGTT), the subjects were divided into the GDM group (131) and control group (135). The level of serum 25(OH)D at the time of OGTT were detected and other clinical indicators were followed up. ResultsThe age, systolic blood pressure in early pregnancy, pre-pregnancy BMI, FPG, OGTT 1-hour and 2-hour glucose, GHb, HOMA-IR, TG, AST, Cr, D-D, FDP and SF at 35 weeks’ gestation of the pregnant women were higher in the GDM group than that of the pregnant women in the normal group, while gestational weight gain and serum 25(OH)D level were significantly lower than that of the pregnant women in the normal group. Serum 25(OH)D was negatively correlated with HOMA-IR and WBS’s, but positively correlated with TG and ALT. Serum 25(OH)D was non-linearly correlated with the risk of GDM in an inverted J-shape, and there was an interaction effect of advanced age, pre-pregnancy obesity and vitamin D deficiency on the risk of GDM. ConclusionVitamin D is non-linearly associated with the risk of GDM. The risk of GDM is significantly reduced when serum 25(OH)D level ≥30 ng∙mL-1.

Objective:To study the clinicopathological features of Sjogren′s syndrome (SS) with liver injury and to improve the understanding of this disease.Methods:Forty-nine patients with SS complicated with liver injury were collected from Beijing Ditan Hospital, Capital Medical University from October 2008 to January 2022. All patients underwent ultrasound-guided liver biopsy, and all specimens were stained with HE. The histopathologic characteristics were observed and the pathologic indexes were graded. Immunohistochemical stains for CK7, CK19, CD38, MUM1 and CD10 were performed by EnVision method; and special histochemical stains for reticulin, Masson′s trichrome, Rhodanine, Prussian blue, periodic acid Schiff (PAS) and D-PAS stains were conducted .Results:The age of patients ranged from 31 to 66 years, including 3 males and 46 females. SS combined with drug-induced liver injury was the most common (22 cases, 44.9%), followed by autoimmune liver disease (13 cases, 26.5%, including primary biliary cholangitis in eight cases, autoimmune hepatitis in 3 cases, and PBC-AIH overlap syndrome in 2 cases), non-alcoholic fatty liver disease (NAFLD, 9 cases, 18.4%) and other lesions (5 cases, 10.2%; including 3 cases of nonspecific liver inflammation, 1 case of liver amyloidosis, and 1 case of porto-sinusoidal vascular disease). Among them, 28 cases (57.1%) were associated with obvious interlobular bile duct injury, mainly in SS combined with PBC group and drug-induced liver injury group. Twenty-three cases (46.9%) were associated with hepatocyte steatosis of varying degrees. In SS with autoimmune liver disease group, ISHAK score, degree of fibrosis bile duct injury, bile duct remodeling, lymphocyte infiltration of portal area, and plasma cell infiltration, MUM1 and CD38 expression; serum ALP and GGT, IgM; elevated globulin; positive AMA, proportion of AMA-M2 positive and IgM positive were all significantly higher than those in other groups(all P<0.05). Serum ALT, direct bilirubin and SSA positive ratio in SS combined with drug liver group were significantly higher than those in other groups(all P<0.05). The serum total cholesterol level in SS combined with PBC group ( P=0.006) and NALFD group ( P=0.011) were significantly higher than those in other groups ( P<0.05). Conclusions:The pathologic manifestations of SS patients with liver injury are varied. The inflammatory lesions of SS patients with autoimmune liver disease are the most serious, and the inflammatory lesions of SS patients with non-alcoholic fatty liver disease and non-specific inflammation are mild. Comprehensive analysis of liver histopathologic changes and laboratory findings is helpful for the diagnosis of SS complicated with different types of liver injury.

Objective:To explore the association between thyroid function and chronic kidney disease (CKD) in adults.Methods:A cross-sectional study was conducted in adults who received health checkup in the First Affiliated Hospital of Shandong First Medical University from January to December in 2021. Clinical data were collected, including age, gender, height, weight, blood pressure, etc. And blood glucose, blood lipid, blood creatinine, blood uric acid, routine urine function, thyroid function (free triiodine, free thyroxine, thyroid stimulating hormone) were measured. Multivariate logistic regression model was used to investigate the correlation between thyroid function indicators and the onset of CKD; and receiver operator characteristic (ROC) curve was used to explore the ability of thyroid function indicators in evaluating CKD.Results:In the study, 46 342 adults with an average age of (47.6±14.3) years were enrolled, of which 56.2% were males. The prevalence of DeGFR (eGFR<60 ml·min -1·(1.73 m 2) -1), proteinuria and CKD was 1.15%, 0.53% and 1.58%, respectively. The TSH subgroup analysis showed that the prevalence of DeGFR, albuminuria and CKD in the hypothyroidism group was significantly increased to 1.07%, 2.36% and 3.20%, respectively (all P<0.05). After adjusting for confounding factors, multivariate logistic regression analysis showed that FT3 was negatively associated with CKD ( OR=0.63, 95% CI: 0.54-0.74), however FT4 ( OR=1.05, 95% CI: 1.03-1.07) and TSH ( OR=1.03, 95% CI: 1.01-1.04) were positively correlated with CKD. Similar results were obtained in the subgroup without hypertension and diabetes ( P<0.05). The ROC analysis indicated that FT3 had a better capability for evaluating CKD than FT4 and TSH, with an area under the curve of 0.63, a cut-off value of 4.18 pmol/L, and a sensitivity and specificity of 57.5% and 62.6%, respectively. Conclusions:Thyroid function status is closely associated with the onset of CKD in the adult population receiving health check-up. FT3 is a risk factor for the onset of CKD.
