Objective: To analyze the changes in serum ghrelin and leptin levels in girls with central precocious puberty (CPP) after 24 weeks of aerobic training combined with gonadotropin releasing hormone agonist (GnRH-a) therapy, so as to provide reference for preventing girls from precocious puberty. Methods: A total of 96 girls with CPP who were treated at the Affiliated Huai an Hospital of Xuzhou Medical University between April 2022 and January 2024 were selected as study subjects. They were divided into a pharmacotherapy group and a combined pharmacotherapy and aerobic exercise group by random number table method, with 48 patients in each group. The pharmacotherapy group received subcutaneous injections of leuprorelin acetate microspheres at a dose of 100 μg/kg in the morning (8:00-10:00), administered once every 4 weeks for a total of 6 injections. The combined pharmacotherapy and aerobic exercise group participated in aerobic exercise in addition to the subcutaneous injections of leuprorelin acetate microspheres; the training was conducted for 24 weeks, 3 times per week, and was conducted after school for girls, for 20- 75 min per session. The t test was utilized to comparatively analyze the serum leptin and ghrelin levels of the patients in both groups before and after the intervention. Binary Logistic regression analysis was applied to explore the correlative factors influencing serum ghrelin and leptin levels in girls with CPP post intervention. Results: Following the intervention, the serum leptin [(7.85± 1.43)ng/mL ] and ghrelin [(8.46±1.06)ng/mL] levels in the girls of the pharmacotherapy group demonstrated no statistically significant changes compared to their pre intervention levels [(7.94±1.45) (8.35±1.22)ng/mL, respectively] ( t =0.41, -0.58, both P > 0.05 ). Conversely, in the combined pharmacotherapy and aerobic exercise group, the post intervention serum leptin levels [(6.35±1.62) ng/mL] significantly decreased compared to pre intervention [(7.87±1.59) ng/mL], and the serum ghrelin levels [(9.12±1.37) ng/mL] significantly increased compared to pre intervention [(8.22±1.47) ng/mL] ( t =6.20, 4.39, both P <0.05). Conclusion Aerobic training increases serum ghrelin levels and decreases serum leptin levels in girls with CPP.

Objective: To explore the causal link of cumulative ecological risk and future orientation with health risk behaviors among higher vocational college students, so as to provide reference for reducing and preventing health risk behaviors among higher vocational college students. Methods: A longitudinal follow up study was conducted on 612 students using convenience sampling from 2 vocational colleges in Hunan Province. The Cumulative Ecological Risk Scale, Future Orientation Scale, and Health Risk Behavior Scale were used during three follow up visits (T1: September 2022, T2: June 2023, T3: March 2024), and a cross lagged panel model was constructed to examine the longitudinal causal relationship of cumulative ecological risk, future orientation and health risk behaviors. Analysis of longitudinal intermediary effect between variables by Bootstrap. Results: The cumulative ecological risk scores of T1, T2 and T3 among higher vocational college students were (2.94±1.44,2.99±1.63,3.02±1.54), future orientation scores (40.49±4.71,41.51±5.72,41.06±4.35) and health risk behavior scores (3.73±2.01,3.49±2.00,3.23±2.00). The results of repeated measures ANOVA showed that the future orientation score of T2 was higher than that of T1, and the main effect of measurement time was statistically significant ( F=5.09，P＜0.01,η 2=0.02). The health risk behavior score of T1 was higher than that of T2, and the health risk behavior score of T2 was higher than that of T3, and the main effect of measurement time was statistically significant ( F=10.12，P＜0.01,η 2=0.03).The cross lagged model showed good adaptability, with χ 2/df =7.20 ( P <0.01), relative fitting indicators GFI=0.98, CFI=0.99, TLI=0.96, IFI=0.99, NFI =0.99, and absolute fitting indicator RMSEA =0.06. Among them, the T1, T2 cumulative ecological risk showed negatively predictive effects on T2, T3 future orientation ( β =-0.24, -0.47 ), and T1, T2 cumulative ecological risk positively predicted T2, T3 health risk behavior ( β =0.20, 0.24), while T1, T2 future orientation negatively predicted T2, T3 health risk behavior ( β =-0.25, -0.18) ( P ＜0.01). Bootstrap test analysis found that T2 future orientation had a longitudinal mediating effect ( β=0.04, P ＜0.01) on the T1 cumulative ecological risk and T3 health risk behavior. Conclusions The accumulation of ecological risk among higher vocational college students can positively predict health risk behaviors, while future orientation can negatively predict healthrisk behaviors. Moreover, future orientation plays a longitudinal mediating role between accumulated ecological risks and health risk behaviors.

With the main pathological features of glomerulosclerosis and interstitial fibrosis， renal fibrosis is a key pathological process causing chronic kidney disease to progress to end-stage disease. As a cellular autophagic process， mitochondrial autophagy plays a crucial role in maintaining mitochondrial mass and functional stability. Mitochondrial dysfunction is considered to be one of the key factors driving the progression of fibrosis. Phosphatase and tension protein homologue （PTEN） induce various signalling pathways such as putative kinase 1/parkin， Nip3-like protein X/Bcl-2 interacting protein 3， and FUN14 structural domain-containing protein 1 to activate mitochondrial autophagy to participate in the regulation of fibrogenic factors， amelioration of oxidative stress， and inhibition of inflammatory response and apoptosis， which in turn effectively slows down the progression of renal fibrosis. Studies have shown that traditional Chinese medicine monomers and compound preparations， including phenolics， terpenoids， ketones， and alkaloids， can regulate mitochondrial autophagy-related signalling pathways and achieve significant clinical efficacy in intervening in the progression of renal fibrosis for the treatment of chronic kidney disease. This paper summarized the mechanism of mitochondrial autophagy and the research progress of traditional Chinese medicine intervention in renal fibrosis to provide new ideas for the study of the mechanism of traditional Chinese medicine in treating renal fibrosis.

Objective:To analyze the factors associated with the occurrence of dysphagia after endoscopic submucosal dissection(ESD) treatment in patients with early esophageal cancer or precancerous lesions, and to explore their clinical predictive value.Methods:From March 1, 2020 to March 31, 2021, 35 patients diagnosed with early esophageal cancer or precancerous lesions without dysphagia before ESD treatment were recruited. All the patients were followed up for 2 years after ESD, and were divided into the non-dysphagia group (22 cases) and dysphagia group (13 cases) according to the occurrence of postoperative dysphagia. The demographic characteristics(such as gender and age), ESD-related data (such as the range of circumferential resection), the parameters of high resolution esophageal manometry such as distal contraction integral(DCI), the amplitude of peristaltic waves in various esophageal segments, and the psychological states such as self-rating anxiety scale (SAS) scores of the 2 groups were analyzed. Multivariate logistic regression was used to analyze the independent influencing factors for the occurrence of dysphagia after ESD and receiver operating characteristic curve (ROC) of the independent risk factors was plotted to assess the diagnostic efficacy.Results:The result of multivariate logistic regression analysis showed that the range of circumferential resection ( OR=23.881, 95% confidence interval (95% CI) 4.073 to 140.022), the SAS score ( OR=1.157, 95% CI 1.029 to 1.300), the mean value of DCI ( OR=0.864, 95% CI 0.750 to 0.995) and the maximum value of DCI ( OR=0.914, 95% CI 0.837 to 0.998) were independent influencing factors for postoperative dysphagia (all P<0.05).The result of ROC analysis showed that the area under the curve for the range of circumferential resection predicting dysphagia after ESD was 0.895 (95% CI 0.788 to 0.987, P<0.001), with an optimal cut-off value of 72.50, and the area under the curve for SAS score was 0.811 (95% CI 0.660 to 0.962, P=0.001), with an optimal cut-off value of 34.38. Conclusions:Reduced distal esophageal pressure, and(or) contractile weakness may contribute to dysphagia after ESD. Postoperative dysphagia risk increases when the range of circumferential esophageal resection exceeds 72.5% of the lumen circumference or the SAS score is over 34.

Objective:To investigate the driving effect of prostate cancer associated transcript 4 (PCAT4) on the up-regulation of upregulator of cell proliferation (URGCP) expression in breast cancer progression through sponging miR-508-5p.Methods:The microarray data of lncRNA and miRNA with differential expression in breast cancer tissue were analyzed by Cancer Genome Atlas. The expression of PCAT4 in breast cancer was evaluated by real-time quantitative polymerase chain reaction (RT-qPCR). Cell proliferation was measured by MTT and colony formation, cell apoptosis was analyzed by TUNEL, and cell migration and invasion were analyzed by Transwell. The correlation between PCAT4 and miR-508-5p, and miR-508-5p and URGCP was analyzed by RNA pull-down and double luciferase assay. Tumor xenograft studies were performed to analyze the correlation between PCAT4/miR-508-5p/URGCP axis and breast cancer cell growth in vivo. Measurement data were expressed as mean ± standard deviation ( ± s). T-test was used for comparison between two groups, and one-way analysis of variance was used for comparison between multiple groups. The correlation between PCAT4 and URGCP and miR-508-5p expression was evaluated by Pearson correlation analysis. Results:The expression level of PCAT4 was up-regulated in breast cancer tissues and cells. Knockout of PCAT4 inhibited cell proliferation and metastasis and promoted cell apoptosis. miR-508-5p was the target of PCAT4 and was negatively correlated with PCAT4. Overexpression of miR-508-5p in breast cancer can inhibit cell growth, migration and invasion, and promote cell apoptosis. URGCP is the target of miR-508-5p and induces progression of breast cancer. Tumor xenograft studies showed that PCAT4 drives breast cancer progression by affecting miR-508-5p/URGCP.Conclusion:The expression of PCAT4 is up-regulated in breast cancer tissues and cells, and PCAT4 can act as a molecular sponge of miR-508-5p, and significantly promote breast cancer progression by activating URGCP protein expression.
