ABSTRACT
Objective:To analyze the relationship between early-life famine exposure and the risk of metabolic syndrome in Chinese population.Methods:Relevant literature on the relationship between early-life famine exposure and the risk of metabolic syndrome in the Chinese population was retrieved from databases such as CNKI, Wanfang, VIP, CBM, Web of Science, and PubMed. The search was conducted from the inception of the databases up to October 2022. Two researchers independently extracted and systematically evaluated the data from the literature, and meta-analysis was performed using Stata 16.0 software. Results:A total of 12 publications met the inclusion criteria, including 71 470 study subjects. Meta-analysis results showed that early-life famine exposure increased the risk of metabolic syndrome in the Chinese population( OR=1.28, 95% CI 1.16-1.40). Subgroup analysis showed that both fetal famine exposure( OR=1.25, 95% CI 1.03-1.52) and childhood famine exposure( OR=1.29, 95% CI 1.15-1.45) increased the risk of developing metabolic syndrome compared to the non-exposed group, and this significant association was only found in the female population. Conclusion:Early-life exposure to famine may increase the risk of developing metabolic syndrome in adulthood in the Chinese population, particularly among females.
ABSTRACT
Type 2 diabetes mellitus(T2DM)is a common chronic metabolic disease,while there is no consistent conclusion on the pathogenesis of T2DM.With the innovation of microecological research technology,intestinal dysbiosis is considered to be one of the causes of T2DM.Exercise is one of the effective means of diabetes management,while mechanism of regulating glucose metabo-lism still has many problems to be solved.In recent years,people have found that exercise can improve the intestinal environment and intestinal flora.This article will review the research on the influence and mechanism of exercise on T2DM based on intestinal flora,aiming to provide new ideas for exploring how exercise can improve T2DM in the future.
ABSTRACT
@#Objective To analyze the correlation between the gray value of epicardial fat and the prognosis of patients with atrial fibrillation (AF) treated by thoracoscopic radiofrequency ablation. Methods The clinical data of 97 patients, including 75 males and 22 females with an average age of 57.8±9.4 years, who underwent thoracoscopic radiofrequency ablation in Fuwai Hospital from 2017 to 2018 were analyzed retrospectively. The left atrial fat volume and average gray scale were calculated by left atrial enhanced CT. According to the average gray scale of left atrial fat tissue, the patients were divided into three groups: a high gray scale group, a medium gray scale group and a low gray scale group. The patients were followed up at 3, 6 and 12 months after operation. The end point of follow-up was the recovery rate of sinus rhythm. Survival analysis was used to analyze the correlation between CT features of epicardial fat enhancement and prognosis. Results After adjustment of body mass index, body surface area, gender and left atrial end diastolic diameter, regression analysis showed that the fat gray of left atrial enhanced CT was correlated with the type of AF (OR=0.30, 95%CI 0.12-0.79, P=0.014). Cox regression analysis showed that the fat gray value of left atrial CT predicted the recurrence of AF after thoracoscopic radiofrequency ablation (OR=0.92, 95%CI 0.85-0.99). The Kaplan-Meier curve showed significant difference in the long-term recurrence rate of AF among the three groups (P=0.011). The lower left atrial fat enhanced CT gray scale was, the higher long-term recurrence rate of AF was. Conclusion The gray value of left atrial fat enhanced CT can effectively predict the recurrence of AF after radiofrequency ablation in thoracoscopic surgery.
