Objective: To review the relationship between 24 hour movement behaviors and physical and mental health among college students, in order to provide evidence to support health promotion and further research in universities. Methods: Following the Joanna Briggs Institude(JBI) scoping review guidelines, relevant studies published in databases from inception date to December 26, 2025 were searched, including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Data. For studies meeting the inclusion and exclusion criteria, a descriptive analysis was conducted to summarize the measurement tools used, adherence rates with guidelines, and the relationship between physical and mental health. Results: A total of 30 studies were included. Measurement tools exhibited a high heterogeneity, with questionnaires being the primary method. The rate of full adherence with 24 hour movement behaviors among college students was less than 30%. Moderate to vigorous physical activity and high quality sleep were associated with improvements in physical fitness, cardiopulmonary function, and mental health, while prolonged sitting was negatively associated with obesity and depression. Equivalent time substitution analysis indicated that increasing moderate to vigorous physical activity and reducing prolonged sitting could significantly improve health outcomes. Conclusions The adherence rate for 24 hour movement behaviors among college students is low and it is closely associated with physical and mental health. Future studies should standardize measurement tools, and implement targeted interventions based on the optimization of daily activity patterns.

BACKGROUND:The therapeutic efficacy of moderate or severe intrauterine adhesions is poor.After synechotomy,the high postoperative recurrence rate severely affects the reproductive health of women of childbearing age,which is an urgent problem to be solved in clinical practice.Perinatal mesenchymal stem cells and their combined hydrogels have unique advantages,and they have received particular attention on the treatment of intrauterine adhesions.OBJECTIVE:To summarize the research progress of perinatal mesenchymal stem cells and their combined hydrogel in the treatment of intrauterine adhesions.METHODS:Search terms were"mesenchymal stem cells,perinatal period,hydrogel,intrauterine adhesions,endometrial injury"in Chinese and English.Relative articles published from 2010 to 2024 were retrieved on PubMed,CNKI,and WanFang databases.As a result,80 articles that met the inclusion criteria were reviewed and analyzed.RESULTS AND CONCLUSION:(1)Similar to other sources of mesenchymal stem cells,perinatal mesenchymal stem cells have a good therapeutic effect on intrauterine adhesions,and can meet the needs of autologous and allogeneic transplantation.(2)The mechanism of perinatal mesenchymal stem cell transplantation from umbilical cord,amniotic membrane,placenta,and umbilical cord blood in the treatment of uterine adhesion involves in regulation of relative signaling pathways such as colonization and differentiation,cellular immunity,paracrine,and promoting endometrial regeneration and angiogenesis,immune regulation,anti-endometrial cell apoptosis,inhibition of epithelial-mesenchymal transition,and anti-fibrosis.(3)Perinatal mesenchymal stem cells combined with hydrogel have a synergistic effect on the treatment of intrauterine adhesions.On the basis of the effect of mesenchymal stem cells,the hydrogel also plays a role in supporting and maintaining the continuous release of mesenchymal stem cells,promoting cell migration and adhesion,which is helpful to better promote endometrial regeneration and anti-fibrosis.It is beneficial to repair the damaged endometrial,improve endometrial receptivity and fertility,and reduce the recurrence rate.(4)A few of clinical trials have initially verified the effectiveness and safety of umbilical cord mesenchymal stem cells or hydrogels in the treatment of intrauterine adhesions.Further studies are still needed on the interaction between perinatal mesenchymal stem cells and polymer biomaterials such as hydrogels,and other effects and molecular mechanism of combined treatment of intrauterine adhesions.

AIM:This study aims to investigate of perodic expression,distribution and interaction between es-trogen receptor α(ERα)and ClC-3 chloride channel,and their relevance to the cell cycle specificity of tamoxifen(TAM)in anti-breast cancer treatment.METHODS:We utilized a web database to analyze the correlation between ERα and ClC-3 expression.Three-dimentional molecular simulation software and co-immunoprecipitation were employed to detect and analyze the interactions between these two proteins.To assess cell cycle dynamics,we performed thymidine(TdR)double-blocking release assay and used nocodazole to block the cell cycle,with subsequent analysis via flow cytometry.Cell viability was measured by MTT assay.Western blot was conducted to evaluate the protein expression levels of ERα and ClC-3,while immunofluorescence staining was utilized to assess their subcellular distribution.RESULTS:(1)Anal-ysis from the web database revealed a significant correlation between ERα and ClC-3 expression,and co-immunoprecipita-tion confirmed their interaction.(2)We successfully obtained human breast cancer T47D cells at different cycle stages us-ing the TdR double-blocking release method and nocodazole treatment.(3)Treatment with TAM primarily inhibited T47D cell viability during G2/M phase.(4)Both ERα and ClC-3 exhibited cyclic variations in protein expression,with their sub-cellular distributions showing periodicity and co-localization.(5)Protein interactions between ERα and ClC-3 were ob-served across all cell cycle phases;(6)After TAM treatment,ERα expression peaked in G2/M phase,while ClC-3 expres-sion remained unaffected.CONCLUSION:Our findings demonstrate cyclic differences in the expression and distribution of ERα and ClC-3 in human breast cancer T47D cells,along with confirmed interactions between these two proteins.The cyclic properties of ERα may play a role in mediating the cell cycle specificity of TAM's anti-breast cancer effect.

OBJECTIVE To investigate the mechanism of the inhibitory effect of total flavonoids from Taraxacum mongolicum on high-fat diet-induced obesity in mice through modulation of intestinal flora.METHODS Twenty-four C57BL/6J mice were randomly divided into blank group,model group and T.mongolicum total flavonoid group,with 8 mice in each group.Except for the blank group,the other 2 groups were given a high-fat diet,while T mongolicum total flavonoid group was given T.mongolicum total flavonoid[400 mg/(kg·d)]intragastrically,once a day,for 8 consecutive weeks.During the experiment,the food intake of each group of mice was recorded.After the last medication,the body mass,fat weight,blood lipid level and pathological changes of liver and epididymal fat in mice were evaluated to observe the effect of T.mongolicum total flavonoid on the treatment of obesity in mice.The changes in abundance and structure of intestinal flora in mice were detected by amplicon sequencing;the effects of T.mongolicum total flavonoids on fat metabolism related genes were analyzed by qPCR.RESULTS Compared with model group,the body weight of mice in T.mongolicum total flavonoids group was decreased significantly(P＜0.05);the levels of total lipid cholesterol,triglycerides,and LDL cholesterol were all decreased significantly(P＜0.01),and the level of HDL cholesterol was increased significantly(P＜0.01);the fat indexes of inguinal white adipose tissue and epididymal white adipose tissue were significantly reduced(P＜0.05);significant improvement in hepatocellular steatosis and adipose cytopathy were significantly improved;mRNA expressions of COX7A1 and COX8B were significantly upregulated(P＜0.05).The results of bacterial colony detection showed that compared with the model group,there was a rising trend in the diversity of the bacterial colony in T.mongolicum total flavonoids group,and the Sobs index characterization and β diversity were increased significantly(P＜0.05).Relative abundances of Blautia,norank_f_Ruminococcaceae,Bilophila,Alistipes,classified_f_Ruminococcaceae,Parabacteroides,norank_f_Desulfovibrionaceae,Anaerotruncus were significantly up-regulated(P＜0.05),while those of Faecalibaculum,Erysipelatoclostridium,GCA-900066575,Tuzzerella,Lactobacillus,norank_f_norank_o_RF39,achnospiraceae_FCS020_group were significantly down-regulated(P＜0.05).CONCLUSIONS T.mongolicum total flavonoids can reduce body mass,fat weight and blood lipid levels,and repair the pathological damage to liver and epididymal fat in obese mice,which is related to improving intestinal flora disorders caused by high-fat diet.

Objective:To explore the clinical phenotype and genetic characteristics of four patients with Phelan-McDermid syndrome (PMS) due to variants of SHANK3 gene. Methods:Four patients diagnosed with PMS at Guangzhou Women and Children′s Medical Center Liuzhou Hospital from January 2020 to January 2025 were selected as the study subjects. Clinical data of the patients were collected. Peripheral venous blood samples were collected from each patient for the extraction of genomic DNA, followed by whole-exome sequencing (WES) and validation by Sanger sequencing. Pathogenicity of candidate variants was rated based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), and multiple bioinformatic tools were used to assess the pathogenic effects of the variants. The study was approved by the Ethics Committee of the Guangzhou Women′s and Children′s Medical Center Liuzhou Hospital (Ethics No. 2025-007).Results:All four patients had exhibited language delay and intellectual disability (IQ 35 ~ 65). Some also presented with autism spectrum disorder and schizophrenia, albeit with significant phenotypic heterogeneity. All patients were found to harbor deletions of 22q13.33 region, ranging from 55.46 kb to 112.64 kb, primarily involving the SHANK3 gene. Conclusion:PMS is typically caused by deletions or mutations of the SHANK3 gene. The clinical manifestations are diverse, with developmental delay and intellectual disability being the most common. Accurate diagnosis requires integration of genetic testing and standardized clinical assessment. Genetic screening for suspected patients and at-risk pregnant women is recommended to facilitate their genetic counseling.

The liver is one of the important metabolic organs in the body, and liver diseases are also one of the major public health issues globally. Currently, the lack of models that accurately simulating human physiology and pathology is the key challenge in liver disease research, and the emerging of organoid technology is an excellent solution to this challenge. Organoids are three-dimensional cellular structures cultured in vitro that can mimic the structure and function of real organs while maintaining genetic stability. The development of organoids has provided possibilities for personalized medicine and precision therapy and has become a key tool in the research and treatment of liver diseases. The authors focuse on the application and development of organoids in liver disease research, while also emphasizing their limitations and future prospects.
