ObjectiveTo investigate the recurrence of ischemic stroke (IS) and to analyze the association between four indices of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) and the risk of IS recurrence by analyzing the follow-up data related to IS in the community-based natural population of Songjiang District, Shanghai, so as to provide a scientific basis for improving the prognosis of stroke patients in the community and controlling IS recurrence. MethodsA prospective follow-up study was conducted among the IS patients in the community-based cohort population, collecting data about patient’s age, gender, disease history, biochemical indicators, and etc. Cox regression model and restricted cubic spline model were used to analyze the relationship between different levels of plasma lipids and the recurrence of IS in these patients. ResultsA total of 1 368 patients with IS were included. The total follow-up duration was 7 171.46 person-years, with a median follow-up time of 6.24 years. There were 420 cases of IS recurrence, resulting in a cumulative recurrence rate of 30.70%. The results of multivariate Cox regression analysis showed that the recurrence risk of IS was reduced when the baseline TC and LDL-C levels of IS patients were in the ranges of 4.65‒5.67 mmol·L^-1 and 2.52‒3.46 mmol·L^-1, respectively. The results of restricted cubic spline analysis showed a U-shaped relationship between baseline TC and LDL-C levels and the recurrence risk in IS patients. ConclusionThe cumulative recurrence rate of patients with IS in the community of Songjiang District in Shanghai is high, and the levels of TC and LDL-C at baseline survey are correlated with the recurrence of IS in these patients. It is suggested to pay more attention to the levels of LDL-C and TC in patients with IS, so as to improve the prognosis.

Objective:To explore the prognostic value of serum deoxyribonuclease 1 like 3 (Dnase1L3), C-reactive protein/albumin ratio (CAR) combined with monocyte to high-density lipoprotein cholesterol ratio (MHR) in decompensated hepatitis B cirrhosis patients.Methods:A prospective selection was conducted on 236 decompensated hepatitis B cirrhosis patients (liver disease group) admitted to the Third Hospital of Qinhuangdao from January 2020 to December 2021, and 185 healthy volunteers (control group) who underwent outpatient physical examinations. The serum levels of Dnase1L3, CAR, MHR, and liver function were detected, and Pearson analysis was conducted to investigate the correlation between Dnase1L3, CAR, MHR, and liver function. Tracking the survival status of patients after 30 days of hospitalization, the risk factors affecting 30 day mortality in decompensated hepatitis B cirrhosis patients were analyzed using a multivariate logistic regression equation. The receiver operating characteristic (ROC) curve analysis was used to assess the value of Dnase1L3, CAR, and MHR in predicting 30 day in-hospital mortality in decompensated hepatitis B cirrhosis patients.Results:The serum levels of Dnase1L3, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBiL), CAR, and MHR in the liver disease group were higher than those in the control group (all P<0.05). The serum levels of Dnase1L3, CAR, and MHR in the liver disease group were positively correlated with AST, ALT, and TBiL (all P<0.05). Among 236 patients, 32 died within 30 days. Model for end-stage liver disease (MELD) scores>18, high Dnase1L3, high CAR, and high MHR were risk factors for 30 day mortality in decompensated hepatitis B cirrhosis patients (all P<0.05). The combined prediction of Dnase1L3, CAR, MHR, and MELD scores for 30 day mortality in decompensated patients with hepatitis B cirrhosis showed an area under the curve of 0.904, which was higher than the predicted values of 0.719, 0.678, 0.763, and 0.742 for individual indicators. Conclusions:The serum Dnase1L3 levels, CAR, and MHR are elevated in patients with decompensated hepatitis B cirrhosis, and are associated with the degree of liver function damage and mortality within 30 days of hospitalization. They have high value in predicting the prognosis of decompensated hepatitis B cirrhosis.

ObjectiveTo analyze the incidence， recovery rate and associated factors of nonalcoholic fatty liver disease （NAFLD） among residents aged 65 years old and above in Xinqiao Community of Songjiang， Shanghai， and to provide basic data for further efficient community management. MethodsData of annual geriatric physical examination program for residents aged 65 and above were collected in Xinqiao Community， Songjiang from 2016 to 2022. Those residents who participated twice or more were included in this analysis. Data were collated into longitudinal form. For each participant， data of the first physical examination was used as baseline， and each subsequent examination was taken as follow-up. Incidence and recovery rate of NAFLD were calculated. Cox proportional hazard models were used to explore the associated factors and their changes with the onset and recovery of NAFLD. ResultsDuring the study period， a total of 11 983 residents participated in physical examinations， of which 8 644 participated twice or more， and 8 154 had no history of excessive alcohol consumption. B-ultrasound showed that there were 5 267 residents without NAFLD and 2 887 with NAFLD at baseline. After a median follow-up of 3.3 years， the incidence density of NAFLD in this population was estimated to be 11.5 per 100 person-years， and the recovery density was 23.4 per 100 person-years. The incidence density of NAFLD was negatively associated with age， and positively associated with baseline BMI， abdominal obesity， high fasting blood glucose， and high triglycerides. The recovery density was negatively associated with baseline BMI and abdominal obesity. Compared with those with normal BMI at both baseline and follow-up， those with persistent obesity showed the highest risk of NAFLD （males： HR： 3.19， 95%CI： 2.16-4.70； females： HR： 3.34， 95%CI： 2.46-4.54） and the lowest potential of recovery （males： HR： 0.58， 95%CI： 0.42-0.82； females： HR： 0.58， 95%CI： 0.44-0.77）. Persistently high triglycerides were also associated with a higher risk of developing the disease. ConclusionResidents aged 65 years old and above in Xinqiao， Shanghai had a higher incidence and recovery rate of NAFLD. Women， being obese and having hyperlipidemia are at a higher risk for the development and persistence of NAFLD.

Objective:To investigate the application value of serum fibroblast growth factor 21 (FGF21) levels in assessing disease status in patients with liver cancer.Methods:A cross-sectional study was conducted involving 157 hospitalized patients who received treatment at the Department of Infectious Disease, The First Hospital of Jiaxing between July 2020 and August 2021 (54 patients with liver cancer and 103 patients with chronic liver disease). General patient data were collected, and serum FGF21 levels were measured using the enzyme-linked immunosorbent assay. Pearson correlation analysis was performed to investigate the correlation between FGF21 levels and various indicators. Logistic regression analysis was performed to identify risk factors associated with the severity of liver cancer. Receiver operating characteristic curve analysis was conducted to evaluate the predictive value of FGF21 levels for liver cancer.Results:Serum FGF21 levels differed significantly between the liver cancer and chronic liver disease groups [399.91 (293.05, 572.65) ng/L vs. 174.16 (105.39, 255.16) ng/L, Z = 7.32, P < 0.001). Pearson correlation analysis indicated that FGF21 levels were positively correlated with sex, age, smoking, alcohol consumption, fasting blood glucose, total bilirubin, and prothrombin time (all P < 0.05). Logistic regression analysis revealed that FGF21 is an independent risk factor for liver cancer ( OR = 1.102, P < 0.001). According to the receiver operating characteristic curve, the area under the curve for FGF21 levels was 0.856, with an optimal cutoff value of 274.99 ng/L. This cutoff value demonstrated a sensitivity of 0.833 and a specificity of 0.796 for predicting liver cancer. Conclusion:In patients with liver cancer, elevated levels of FGF21 can be observed even when fasting blood glucose is normal, indicating its potential as a predictor for the occurrence of liver cancer. Furthermore, increased FGF21 levels are an independent risk factor for the development of liver cancer.
