Mediating effect of physical sub-health in the association of sugar-sweetened beverages consumption with depressive symptoms in Chinese college students: A structural equation model.

BACKGROUND: Although previous findings with small samples indicated that sugar-sweetened beverages (SSB) consumption was associated with depressive symptoms in adolescents, the mediating effect of physical sub-health in the association is unknown. METHODS: A survey was conducted among freshmen from 11 provinces in China. A food frequency questionnaire was used to collect dietary behavior, and patient health questionnaire-9 items was used to assess depressive symptoms. A generalized linear model was used to analyze the association between SSB consumption, physical sub-health and depressive symptoms. The structural equation model was used to analyze the mediating effect of physical sub-health. RESULTS: Of the 31,856 participants, 36.5 % had positive depressive symptoms. After adjusting for variables, carbonate beverages (ß = 0.11; 95%CI: 0.07-0.15; P = 0.000) and milk tea (ß = 0.07; 95%CI: 0.01-0.13; P = 0.021) consumption was associated with depressive symptoms in boys. Carbonate beverages (ß = 0.09; 95%CI: 0.05-0.13; P = 0.000), tea beverages (ß = 0.09; 95%CI: 0.04-0.13; P = 0.000), and milk tea (ß = 0.08; 95%CI: 0.04-0.11; P = 0.000) consumption was associated with depressive symptoms in girls. The mediating effect of physical sub-health accounted for 81.3 % of the total effect in the mediating model of SSB associated with depressive symptoms. LIMITATIONS: Retrospective survey has certain information bias. Association observed in the cross-sectional study is uncertain. CONCLUSIONS: The present study suggests that the consumption of SSB associated with depressive symptoms in Chinese college students, and physical sub-health plays a complete mediating role in the association.

Clinical effectiveness of endoscopic versus surgical treatment of chronic pancreatitis: a meta-analysis / 中华肝胆外科杂志

Objective:To compare the efficacy of endoscopy and surgery in chronic pancreatitis.Methods:CNKI, CBM, Wanfang, PubMed, Cochrane Library, Embase and Web of Science were searched to compared endoscopy and surgery for the clinical efficacy of chronic pancreatitis. Literatures were searched from the establishment of the database to August 14, 2022. Compared pain relief, clinical response to initial treatment, complications, endocrine/exocrine insufficiency, length of hospital stay and mean number of procedures between the two groups. Manager 5.4.1 software was used for data analysis. Odds ratio ( OR) or weighted mean difference ( WMD) was calculated with 95% confidence interval (95% CI). Results:A total of seven studies were included, including three randomized controlled trials and four retrospective studies with 708 patients. There were 513 males and 195 females. Endoscopic interventions were performed in 364 patients and 344 patients underwent surgery. The results of meta-analysis showed that the total pain relief rate ( OR=0.38, 95% CI: 0.24-0.59) and the complete pain relief rate ( OR=0.47, 95% CI: 0.29-0.77), short-term (1-1.5 years) pain relief rate ( OR=0.42, 95% CI: 0.24-0.74), clinical relief rate ( OR=0.23, 95% CI: 0.10-0.55) were better than the endoscopic group, and could significantly reduce the number of reoperation ( WMD=1.64, 95% CI: 0.89-2.40), and the difference was statistically significant (all P<0.05). There were no significant differences in complications, new-onset endocrine insufficiency, new-onset exocrine insufficiency and length of hospital stay between the endoscopy group and the surgical group (all P>0.05). Conclusion:Surgical intervention is superior to endoscopic treatment in controlling pain associated with chronic pancreatitis and in clinical relief after the first treatment, and can effectively reduce the number of reoperations.

Application of circulating free DNA in the diagnosis and treatment of hepatocellular carcinoma / 临床肝胆病杂志

Hepatocellular carcinoma has a low early diagnostic rate, and there is a lack of highly sensitive and specific tumor markers. In recent years, fluid biopsy technique, represented by circulating free DNA (cfDNA), has become an auxiliary method for the diagnosis of cancer and has attracted more and more attention due to its advantages of noninvasiveness, convenience, and repeatability. With reference to the recent studies in China and foreign countries, this article summarizes and analyzes the advances in cfDNA in the diagnosis and treatment of hepatocellular carcinoma from the aspects of biological characteristics, detection techniques, and clinical application, so as to provide a basis for clinical diagnosis and treatment.
