Objective: To explore the association between meat consumption and anxiety symptoms in first year junior high school students in Yunnan Province, and to provide theoretical support for preventing and relieving anxiety symptoms in junior high school students. Methods: From October to December 2022, a random cluster sampling method was used to select 8 500 first year junior high school students from 11 counties in Yunnan Province as the survey subjects for a questionnaire survey. The study used Food Frequency Questionnaire and the Chinese version of the Depression Anxiety Stress Scale-21 (DASS-21) to assess the meat consumption and anxiety symptoms of junior high school students.The distribution differences in anxiety symptoms among first year junior high school students with different demographic characteristics were analyzed statistically by using the Chi-square test,and the association between meat consumption and anxiety symptoms in students was analyzed by using a generalized linear model. Results: The detection rate of anxiety symptoms was 48.47%. After controlling for demographic variables and confounding factors, the consumption of livestock meat, poultry meat, processed meat, cured meat, barbecued meat and raw skin meat was statistically significant with anxiety symptoms ( β =-0.05, 0.04, 0.04, 0.08, 0.14, 0.17, all P <0.05). Stratified by ethnicity, The consumption of livestock meat, cured meat and barbecue was statistically correlated with anxiety symptoms in Han adolescents ( β =-0.07, 0.14, 0.22 ); the consumption of processed meat and raw skin meat was statistically correlated with anxiety symptoms in ethnic minority adolescents ( β =0.08, 0.18) (all P <0.05). Conclusions There is a statistical association between meat comsumption and the risk of anxiety symptoms in first year junior high school students in Yunnan Province. Guidance on meat consumption should be strengthened to prevent the occurrence of anxiety symptoms.

Polygonatum sibiricum， as a traditional Chinese medicine with both medicinal and edible properties， has attracted considerable attention due to its functions of nourishing Yin and moistening the lungs， tonifying the spleen and benefiting Qi， and nourishing the kidneys and filling essence. Recent studies have demonstrated that Polygonatum sibiricum plays a significant role in regulating the immune system， effectively enhancing and improving the morphology and function of immune organs， stimulating the proliferation and activation of immune cells， and regulating the secretion and release of immune factors， thereby enhancing the immune function of the body and improving various immune-related diseases. Although a large number of studies have explored the pharmacological effects and mechanisms of P. sibiricum， there has been no systematic review and summary of its immune regulatory activity and mechanisms. Therefore， this article comprehensively reviews the research achievements of P. sibiricum polysaccharides and saponins in the field of immune regulation in recent years， and further sorts out the immune regulatory mechanisms of P. sibiricum in multiple aspects： including increasing the organ index of the spleen and thymus， increasing the number and activity of tumor-suppressive bone marrow hematopoietic stem cells， improving intestinal flora imbalance， regulating the quantity and proportion of T lymphocyte subsets， increasing the level of immunoglobulin， promoting the proliferation of macrophages， enhancing the activity of natural killer cells， increasing the number of white blood cells， and promoting the maturation of dendritic cells， providing a solid theoretical basis and scientific evidence for the research and application of P. sibiricum， and promoting its development and application in traditional Chinese medicine immune enhancers and various functional products.

Objective: To explore the relationship between processed food consumption and blood pressure level of students in a university in Yunnan Province, so as to provide the reference for preventing hypertension in university students. Methods: In October 2021, a cluster sampling method was used to select 4 781 freshmen from a university in Kunming, Yunnan Province. The frequency of processed food consumption of university students was assessed by using the dietary frequency questionnaire, and height, weight and blood pressure were measured. Mann-Whitney test and Kruskal-Wallis test were used to compare the differences in blood pressure level of university students with different demographic variables, and the association between processed food consumption and blood pressure level was analyzed with a generalized linear model. Results: Among the students of a university in Yunnan Province, the detection rates of systolic prehypertension and hypertension were 33.86% and 1.23%, and the detection rates of diastolic prehypertension were 32.13% and hypertension 7.22%. The results of generalized linear model analysis showed that after controlling for demographic variables and other variables that might affect the blood pressure level of university students, the consumption of processed food (bread and cake: β =0.15, 95% CI =0.01-0.29) and ultra processed food (coffee beverage: β =-0.29, 95% CI =-0.54--0.03) were associated with systolic blood pressure level( P <0.05). The consumption of processed food (salted duck egg: β =0.21, 95% CI =0.01-0.41) was correlated with the diastolic blood pressure of college students ( P <0.05). Conclusions Processed food consumption in university students may increase the risk of high blood pressure.The education of healthy eating among college students should be strengthened to reduce the consumption of processed foods.

Objective To study the therapeutic effect of Xuefu Zhuyu Capsule combined with sacubitril valsartan on dilated cardiomyopathy.Methods A total of 70 patients with dilated cardiomyopathy who were hospitalized in the Hospital from January to December 2020 were selected as the research objects and random-ly divided into control group and experimental group,with 35 cases in each group.The control group was only treated with sacubitril valsartan,and the experimental group was treated with Xuefu Zhuyu Capsule combined with sacubitril valsartan.According to the patient's blood pressure and renal function,sacubitril valsartan was titrated from a small dose to the maximum dose.Xuefu Zhuyu Capsule was uesd 2.4 g each time,twice a day,and the treatment time was three months.The symptoms of heart failure,glycosylated hemoglobin(HbA1c),low density lipoprotein(LDL),total cholesterol(TC),triglyceride(TG),ALT,AST,N-terminal pro-brain natriuretic peptide(NT-proBNP),left ventricular end-systolic diameter(LVEDd),left ventricular end-dias-tolic diameter(LVEDs),ejection fraction(EF)and the incidence of arrhythmia were observed in the two groups after treatment.Results After treatment,the level of NT-proBNP in the experimental group was sig-nificantly lower than that in the control group(P＜0.05).There was no significant difference in LDL,TC,TG,LVEDd,LVEDs and EF between the two groups(P＞0.05).The incidence of atrial tachycardia and ven-tricular premature beat in the experimental group was higher than that in the control group(P＜0.05).Con-clusion Xuefu Zhuyu Capsule combined with sacubitril valsartan can significantly improve the symptoms of patients with heart failure and reduce the level of NT-proBNP,but it may increase the proportion of patients with atrial tachycardia and ventricular premature beats.

Objective To investigate the application of artificial intelligence-based follow-up plan for patients after percutaneous coronary intervention(PCI).Methods The follow-up plan of artificial intelligence after PCI was constructed through literature review and expert correspondence consultation.A total of 82 patients with coronary heart disease who underwent PCI in the Second Affiliated Hospital of Nanchang University from October 2022 to November 2023 were selected and divided into intervention group and control group according to random number table method,with 41 cases in each group.The control group was given routine nursing program,and the intervention group was added artificial intelligence-based follow-up program on the basis of control group.The incidence of major adverse cardiovascular event(MACE)within 6 months,30 days readmission rate,medication compliance and satisfaction score were compared between two groups.Results The incidence of MACE within 6 months and 30 days readmission rate in intervention group were significantly lower than those in control group(P＜0.05).After 6 months of intervention,Morisky scale score and satisfaction score of patients in two groups were significantly higher than before intervention(P＜0.05),and Morisky scale score and satisfaction score of patients in intervention group were significantly higher than those in control group(P＜0.05).Conclusion Follow-up program based on artificial intelligence technology can reduce the incidence of MACE and 30 days readmission rate of patients after PCI.

Digestive system malignant tumor is one of the common malignant tumors in humans,and its high morbidity and low survival rate at advanced stages bring heavy disease burden to patients,families and society.However,current tumor screening technologies are not suitable for screening in large-scale populations and long-term follow-up because of the invasiveness or complexity.Thus,liquid biopsy,which based on biomarkers such as circulating tumor DNA,circulating tumor cells,exosomes and other new biomarkers,has broad prospects for development in tumor screening.Exosome,secreted by living cells,is a type of extracellular vesicle with the lipid bilayer.Compared to other biomarkers,exosome has the advantages of high stability,wide distribution,and high quantity.The various proteins carried by exosome can reflect the characteristics of the origin cells,and exosome has important research value for the early diagnosis of tumors.This article reviews the studies of exosomal proteins as biomarkers for early diagnosis of digestive system malignant tumors in the past five years,and summarizes the characteristics and limitations of the above studies,so as to provide reference for promoting the clinical transformation of exosomal proteins.
