Objective: To explore the relationship between snack consumption and depressive symptoms in first year junior high school students with different left behind experiences in Yunnan Province, so as to provide a basis for improving depressive symptoms among first year junior high school students with different left behind experiences. Methods: From October to December 2022,a cluster random sampling method was used to select 8 500 first year junior high school students from 11 ethnic minority areas (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County) in Yunnan Province for a questionnaire survey. The Chinese version of Depression Anxiety Stress Scale-21 was applied to assess depressive symptoms in first year junior high school students, and snack consumption was collected by employing food frequency questionnaire. The generalized linear model was used to analyze the association between first year junior high school students snack consumption and depressive symptoms, and the analysis was stratified according to left behind experience. Results: The detection rates of depressive symptoms among firstyear junior high school students with and without left behind experience were 36.25% and 26.91%, respectively. After controlling for confounding variables, the generalized linear model analysis showed that sweet snacks ( β=0.16, 95%CI =0.07-0.25), fast food ( β=0.14, 95%CI =0.04-0.23) and carbonated drinks ( β=0.09, 95%CI =0.01-0.17) of first year junior high school students with left behind experience (all P <0.05). Compared with those without such behavior, the risk of depressive symptoms was higher in consumption of fast food ( β=0.13, 95%CI =0.07-0.18) and carbonated drinks ( β=0.10, 95%CI =0.06-0.15)among first year junior high school students without left behind experience (both P <0.05). Conclusion Snack consumption among first year junior high school students in Yunnan may increase the risk of developing depressive symptoms, while first year junior high school students with left behind experience may have a greater risk of developing depressive symptoms.

OBJECTIVES: To investigate the characteristics of immune cell infiltration in tumor samples from Chinese patients with clear cell renal cell carcinoma (ccRCC) and the correlation of immune cell infiltration with tumor stage and response to immunotherapy. METHODS: Tumor samples and clinicopathological data were collected from 154 ccRCC patients treated in Nanfang Hospital, Southern Medical University from October, 2020 to October, 2023. The immune cell types infiltrating the tumor tissues were identified using immunohistochemistry and immunofluorescence staining, and their correlations with the patients' clinicopathological characteristics were analyzed. Patient-derived tumor tissue fragment models (PDTF) models, constructed using tumor tissues from 22 patients, were treated with PD-1 monoclonal antibody, and T cell activation was detected using flow cytometry to assess the patients' responses to immunotherapy. RESULTS: In Chinese ccRCC patients included in this study, CD8⁺ T cells, CD4⁺ T cells, and CD3⁺ T cells were the most abundant in the tumor tissues. Higher infiltration levels of CD3⁺ T cells (P=0.004), PD-1⁺ T cells (P=0.020), CD68⁺ T cells (P=0.049), CD79⁺ T cells (P=0.049), and Tryptase⁺ cells (P=0.049) were all positively correlated with a larger tumor size (≥5 cm). A higher infiltration level of CD4⁺ T cells was associated with a lower tumor stage. Patients with higher International Society of Urological Pathology (ISUP) grades had higher infiltration levels of CD3⁺ T cells (P=0.023), CD8⁺ T cells (P=0.045), PD-1⁺ T cells (P=0.014), CD20⁺ B cells (P=0.020) and CD79⁺ B cells (P=0.049), and lower levels of Tryptase⁺ cells (P=0.001). Patients with abundant infiltrating immune cells tended to have better responses to immunotherapy. CONCLUSIONS The infiltrating immune cells are heterogeneous in Chinese ccRCC patients, and immune cell infiltration characteristics are closely correlated with clinicopathological parameters of the patients.

OBJECTIVE To observe the effect of electroacupuncture on insomnia symptoms and blood pressure levels in patients with hypertension and insomnia.METHODS A randomized controlled clinical trial was conducted.A total of 60 patients with hyper-tension and insomnia were enrolled in Jiangsu Province Hospital of Chinese Medicine from December 2021 to December 2022 and ran-domly divided into a treatment group and a control group at a ratio of 1:1,with 30 cases in each group.During the treatment period,2 cases dropped out of the control group and 1 case dropped out of the treatment group.Both groups of patients received sleep and hy-pertension health education and conventional hypertension drug treatment.The treatment group was given electroacupuncture interven-tion,and the control group was given sham electroacupuncture intervention.The treatment course of both groups was 4 weeks.Before and after treatment,the Pittsburgh Sleep Quality Index(PSQI),Insomnia Severity Index(ISI)scale and portable polysomnography(PPSG)were used to evaluate the changes in sleep quality of the two groups of patients;home blood pressure measurement(HBPM)was adopted to evaluate the changes in blood pressure levels of the two groups of patients.Spearman correlation analysis and linear re-gression analysis were used to study the relationship between blood pressure levels and PPSG parameters.RESULTS After treatment,only the sleep onset latency(SOL)and sleep efficiency(SE)of the control group were significantly improved(P<0.05);the PSQI,ISI scores,morning and night systolic blood pressure(SBP),and diastolic blood pressure(DBP)of the treatment group were signifi-cantly reduced(P<0.01),which was better than that of the control group(P<0.05,P<0.01);the sleep parameters of PPSG were significantly improved(P<0.01),which was better than that of the control group(P<0.05,P<0.01).The results of Spearman corre-lation analysis showed that the morning SBP level of patients before treatment was related to the wake time after sleep onset(WASO)and the number of micro-arousals(MAS).After treatment,the decrease in the morning SBP of patients was related to the reduction of MAS and the shortening of SOL.CONCLUSION Electroacupuncture can effectively improve the insomnia symptoms and blood pres-sure levels of patients with hypertension.Its therapeutic mechanism may be related to reducing the number of MAS and improving the degree of sleep fragmentation.

The paper discusses the scientific connotation of"heart and brain co-dominating the mind",including the connotation of"heart and brain co-dominating the mind"in traditional Chinese medicine and the physiological and pathological relationship be-tween heart and brain in modern medicine.Based on the understanding of"heart and brain co-dominating the mind",this paper be-lieves that"restlessness of mind"is the core pathogenesis of insomnia,and regulating mind is the key to the acupuncture and moxibus-tion treatment of insomnia.The autonomic nervous system(ANS)is a bridge connecting the heart and brain,and is closely related to the central anatomy,neurotransmitters and physiological rhythms of sleep.The imbalance of ANS is highly consistent with the patho-genesis of"heart and brain restlessness"in traditional Chinese medicine.The Governor Vessel runs through the brain and the heart,and the"Governor Vessel regulating spirit acupuncture"can communicate the heart and brain,regulate ANS function,and thus im-prove sleep quality.

OBJECTIVE: To construct and validate a predictive model for the therapeutic effect of acupuncture at Tongdu Yangxin prescription (acupoint prescription for promoting the circulation of the governor vessel and nourishing the heart) on insomnia, so as to develop an open-access interactive artificial intelligence (AI)-assisted decision-making platform. METHODS: Clinical data of 139 insomnia patients treated with Tongdu Yangxin acupuncture therapy were included. All the patients had received acupuncture at Baihui (GV20), Yintang (GV24⁺), bilateral Shenmen (HT7), and bilateral Sanyinjiao (SP6); and electric stimulation was attached to Baihui (GV20) and Yintang (GV24⁺), using a continuous wave and a frequency of 2 Hz. The treatment was delivered once every other day, 3 treatments a week, and for 2 consecutive weeks. Patients with Pittsburgh sleep quality index (PSQI) score reduction rate <50% were classified as the "no response group", and those with ≥50% were as the "response group". Outliers were addressed using the 1.5×IQR rule, and missing values were imputed via predictive mean matching. Key features were selected by intersecting the feature importance results from eXtreme Gradient Boosting (XGBoost) and random forest algorithms. After balancing class distribution using the Synthetic Minority Over-sampling Technique (SMOTE), 20% of the data was reserved as a validation set. The remained data underwent the stratified sampling iterations to generate 200 pairs of 3∶1 training-test sets, which was employed for training and internal validation of 8 machine learning algorithms. The optimal algorithm and data partitioning strategy were selected to construct the final model, followed by external validation. The best-performing model was deployed online via Streamlit to create an interactive AI platform. RESULTS: Key predictive features for model construction included insomnia duration, the total PSQI score, PSQI sleep efficiency subscore, the proportion of N1 and N2 sleep stages in total sleep duration, and the maximum pulse rate during sleep. The CatBoost-based model achieved an AUC of 0.92, the average precision of 0.77, and accuracy, average recall, and average F1-score of 0.75 on the test set. On the validation set, it attained an AUC of 0.84, with accuracy, average precision, average recall, and average F1-score all at 0.72, demonstrating robust predictive performance. An interactive AI platform was subsequently developed (https://tdyx-catboost.streamlit.app/). CONCLUSION This study successfully establishes and validates a CatBoost-based efficacy prediction model for Tongdu Yangxin acupuncture therapy in treatment of insomnia. The developed AI platform provides data-driven decision support for acupuncture-based insomnia management.
