Objective: To explore the association between processed food consumption and anxiety symptoms among college students in Yunnan Province, so as to provide a reference for the prevention and treatment of anxiety symptoms in this population. Methods: A cluster random sample of 2 515 first year students from two universities in Yunnan Province was selected to carry out a longitudinal investigation which included a baseline survey (November 2021, T1) and three follow up visits (June 2022, T2; November 2022, T3; June 2023, T4). The food frequency questionnaire was administered to assess processed food consumption, and the Depression Anxiety Stress Scale-21 (DASS-21, Chinese version) was used to evaluate anxiety symptoms. A generalized estimation equation model was used to analyze the relationship between processed food consumption and anxiety symptoms. Results: The detection rates of T1-T4 anxiety symptoms among college students in Yunnan Province were 29.70%, 36.70%, 37.69% and 38.73 %, respectively, and the corresponding anxiety symptom scores were 4(0,8), 4(0,10), 4(0,12), 2(0,14). After controlling for demographic variables and confounding factors in the generalized estimation equation model, a statistically significant association was found between consumption of carbonated beverages ( β=0.06, 95%CI =0.03-0.08), and other processed snacks ( β= 0.04 , 95%CI =0.01-0.07) ( P <0.05). The stratified analysis by gender showed that the consumption of carbonated beverages ( β=0.08, 95%CI =0.05-0.12) and fast food ( β=0.03, 95%CI =0.00-0.06) was significantly associated with anxiety symptoms in female college students ( P <0.05). There was no significant association between processed food consumption and anxiety symptoms in male college students ( P >0.05). Conclusions Processed food consumption by college students in Yunnan Province may increase the risk of anxiety symptoms, particularly among female students. There is a need to strengthen guidance in respect to processed food consumption, so as to prevent and treat anxiety symptoms.

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.

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.
