To investigate body composition and associated factors in adolescents undergoing long-term regular sports training. This prospective longitudinal cohort study employed convenience sampling to recruit adolescents receiving structured athletic training at Jining Sports Training Center in June 2023. Baseline measurements included height, weight, body mass index (BMI), blood pressure, heart rate, waist circumference, and hip circumference. Questionnaires assessed sleep duration, screen time, and household income. Follow-up measurements in June 2024 repeated these assessments while adding bioelectrical impedance analysis for body composition (lean mass, skeletal muscle mass, fat mass, and body fat percentage). Linear regression models examined associations between training type (direct-contact vs. non-contact sports) and follow-up body fat percentage, BMI, and waist circumference as dependent variables, adjusting for covariates. The study included 110 adolescents (39 female, 71 male) with median age 13.21 years (IQR: 12.46-14.33). Participants comprised 65 direct-contact and 45 non-contact athletes. Baseline prevalence rates were 27.27% for overweight/obesity, 24.55% for elevated waist circumference, and 16.36% for elevated blood pressure. At follow-up, corresponding rates were 24.55%, 26.36%, and 13.64% respectively. The elevated blood pressure subgroup showed significantly higher waist circumference ( Despite regular athletic training, substantial proportions of adolescents exhibited overweight/obesity, abdominal obesity, and elevated blood pressure, warranting clinical attention. Training modality appears to influence body composition changes, with direct-contact sports associated with more favorable adiposity-related outcomes.

Based on the etiology and clinical diagnostic criteria of type 2 diabetes mellitus (T2DM), identification and typing of treatment from the perspective of traditional Chinese and western medicine, the criteria for evaluating the clinical compatibility of traditional Chinese and western medicine in animal models of T2DM were set up. The literature was reviewed to sort out and analyze the existing commonly used modeling methods, summarize the mechanism, compare the advantages and disadvantages, and calculate the consistency between the animal model and the clinical symptoms, syndromes, and indicators from the perspective of traditional Chinese and western medicine. The authors found that spontaneous animal models and high-fat diets combined with multiple low-dose streptozotocin (STZ) induction models were more in line with modern medical pathogenesis of T2DM. However, it fails to form some special syndromes required for traditional Chinese medicine (TCM) research. In addition, there are many methods of combining the etiology and pathogenesis of TCM, which can be divided into three categories: intervention carried out by drug administration, behavioral stimulation, or environmental changes according to TCM, or use of hormones according to clinical evidence and combination of the two methods mentioned above. All of them can successfully establish different types of animal models. However, different methods of establishing syndrome models have their own advantages and disadvantages, and there is no unified standard for the stability and evaluation of syndrome models. As for the clinical consistency criteria of traditional Chinese and western medicine established in this paper, the animal model with 100% consistency has not been calculated due to the conditions of incomplete symptoms and syndromes described in the studies and different selection indicators. Consequently, the establishment of a simple, easy-to-use, and affordable T2DM animal model with both traditional Chinese and western medicine disease characteristics and the improvement of the Chinese and western medicine evaluation system for different evidence types are of great significance for the future development of TCM research on T2DM.

Objective To investigate the efficacy and safety of the Corheart 6 left ventricular assist system in patients with end-stage heart failure. Methods A retrospective study was conducted on patients with end-stage heart failure who were treated with Corheart 6 left ventricular assist system from March 2022 to June 2024 in 4 hospitals in Jiangsu Province. The efficacy of the device was evaluated by comparing changes in clinical indicators at preoperative, discharge, 3-month postoperative, and 6-month postoperative timepoints, including the New York Heart Association (NYHA) functional classification, left ventricular ejection fraction (LVEF), and left ventricular end-diastolic diameter (LVEDD). The safety of the device was assessed by analyzing the intraoperative position and orientation of the blood pump inlet cannula, as well as the incidence of adverse events. Results In this study, 39 patients were collected, including 34 males and 5 females with a mean age of (56.4±12.5) years, ranging from 20 to 75 years. There was no operative death. There was no death in postoperative 3 months with a survival rate of 100.0%. There were 3 deaths in 6 months postoperatively, with a survival rate of 92.3%. All patients had a preoperative NYHA cardiac function classification of class Ⅳ. The NYHA cardiac function class of the patients improved (P<0.05) at discharge, 3 and 6 months after surgery when compared to the preoperative period. LVEF was significantly higher at 3 months after surgery than that during the preoperative period (P<0.05). LVEDD was significantly smaller at discharge, 3 and 6 months after surgery than that during the preoperative period (P<0.05). The safety evaluation's findings demonstrated that all 39 patients' intraoperative blood pump inlet tubes were oriented correctly, the artificial blood vessel suture sites were appropriate, there were no instances of device malfunction or pump thrombosis, or instances of bleeding or hemolysis, and the rate of the remaining adverse events was low. Conclusion With a low rate of adverse events and an excellent safety profile, the Corheart 6 left ventricular assist system can efficiently enhance cardiac function in patients with end-stage heart failure. It also has considerable clinical uses.

ObjectiveTo investigate the antidepressant effect of Sinisan (SNS) by regulating glycogen aynthase kinase-3β (GSK-3β)/tumor necrosis factor alpha-induced protein 3(A20)/CCAAT enhancer binding protein β(C/EBPβ) to inhibit the activation of microglia. MethodA total of 72 male C57/6J mice were randomly divided into the normal group, model group, fluoxetine group (5.0 mg·kg-1), low-dose Sinisan group (4.9 g·kg-1), medium-dose Sinisan group (9.8 g·kg-1), and high-dose Sinisan group (19.6 g·kg-1), with 12 mice in each group. After one week of adaptive feeding, chronic unpredictable mild stress (CUMS) was performed to establish the depression model. In the fifth week, drug treatment was conducted for four weeks. In the ninth week, behavioral tests were performed, including sucrose preference test (SPT), open field test (OPT), elevated plus maze (EPM) test, and forced swimming test (FST). Western blot was used to detect the expression levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), nitric oxide synthase (iNOS), GSK-3β, A20, and C/EBPβ in the cortex. The expression of M1-polarized ionized calcium-binding adapter molecule 1 (Iba1) and cluster of differentiation 68 (CD68) in microglia was detected by immunofluorescence. ResultAfter eight weeks of CUMS, compared with the normal group, the mice in the model group had a significantly reduced sucrose preference rate (P<0.01), and the activity in the central area of the OPT was significantly reduced (P<0.01). The activity in the open arm area of the EPM test was significantly reduced (P<0.05), and the immobility time of FST was increased (P<0.01). The expression levels of inflammatory proteins IL-1β, IL-6, and iNOS were increased (P<0.01), and the fluorescence co-localization index of Iba1 and CD68 was increased (P<0.05). The protein expression levels of GSK-3β and C/EBPβ were significantly increased (P<0.05, P<0.01). After four weeks of SNS intervention, compared with the model group, the mice in the SNS group had significantly increased sucrose preference rate (P<0.01), significantly increased activities in the central area and the open arm area in the OPT and the EPM test (P<0.05), and significantly reduced immobility time in the FST (P< 0.01). The protein expression levels of IL-1β, IL-6, and iNOS were significantly decreased (P<0.05), and the fluorescence co-localization index of Iba1 and CD68 was decreased in the high-dose SNS group (P<0.05). The protein expression levels of GSK-3β and C/EBPβ in the medium-dose and high-dose SNS groups were significantly decreased (P<0.01), and that of A20 was significantly increased (P<0.01). ConclusionThe antidepressant effect of SNS is related to the regulation of GSK-3β/A20/C/EBPβ protein expression and the inhibition of M1-type activation of microglia.

BACKGROUND:
There are few multi-city studies on the association between temperature and mortality in basin climates. This study was based on the Sichuan Basin in southwest China to assess the association of basin temperature with non-accidental mortality in the population and with the temperature-related mortality burden.
METHODS:
Daily mortality data, meteorological and air pollution data were collected for four cities in the Sichuan Basin of southwest China. We used a two-stage time-series analysis to quantify the association between temperature and non-accidental mortality in each city, and a multivariate meta-analysis was performed to obtain the overall cumulative risk. The attributable fractions (AFs) were calculated to access the mortality burden attributable to non-optimal temperature. Additionally, we performed a stratified analyses by gender, age group, education level, and marital status.
RESULTS:
A total of 751,930 non-accidental deaths were collected in our study. Overall, 10.16% of non-accidental deaths could be attributed to non-optimal temperatures. A majority of temperature-related non-accidental deaths were caused by low temperature, accounting for 9.10% (95% eCI: 5.50%, 12.19%), and heat effects accounted for only 1.06% (95% eCI: 0.76%, 1.33%). The mortality burden attributable to non-optimal temperatures was higher among those under 65 years old, females, those with a low education level, and those with an alternative marriage status.
CONCLUSIONS
Our study suggested that a significant association between non-optimal temperature and non-accidental mortality. Those under 65 years old, females, and those with a low educational level or alternative marriage status had the highest attributable burden.
