Objective: To investigate the prevalence of overweight and obesity among children and adolescents in Yangzhou City, and its association with screen behaviors, so as to provide scientific evidence for weight management among students. Methods: In May 2025, an electronic questionnaire survey was conducted among children and adolescents in Yangzhou City. A total of 3 722 participants were selected from grades 4 to 12 in 18 primary and secondary schools (108 classes) by using stratified cluster random sampling. The Chi square test was used to compare the differences in the detection rates of overweight and obesity among children and adolescents with 5 types of screen behaviors (watching TV, playing electronic games, scrolling short videos, screen based learning, electronic socializing) in different time groups each day (never, >0~<2 h, ≥2 h). Multivariate Logistic regression analysis was performed to examine the associations of five types of screen behaviors, presence of electronic devices in the bedroom, and screen use during meals on the weight status of children and adolescents. Results: The prevalence of overweight and obesity among children and adolescents was 37.3%. For all five types of screen behaviors, the differences in the distribution of overweight and obesity detection rates among children and adolescents across the three time spent categories were statistically significant ( χ 2=30.76- 70.78 , all P <0.01). After adjusting for confounding factors, multivariate Logistic regression analysis revealed that frequent or always using screens during meals( OR =1.63, 95％ CI =1.14~2.31), playing video games ( OR =1.28, 95% CI =1.11-1.48), browsing short videos ( OR =1.29, 95％ CI=1.09-1.54), and screen based learning ( OR =1.26, 95％ CI =1.10-1.44) were significantly associated with overweight and obesity among children and adolescents (all P <0.05). Conclusions Excessive screen use is positively correlated with the incidence of overweight and obesity in children and adolescents. Targeted interventions on screen behaviors among children and adolescents are therefore warranted.

Objective:To investigate the changes in retinal structure and microcirculation in the patients with high myopia(HM)and the non-HM individuals,and to elucidate the correlations between axial length(AL)and the related parameters.Methods:A total of 80 eyes from 40 patients with simple HM(non-pathological myopia)were enrolled as case group,while 80 eyes from 40 age-and sex-matched non-HM subjects were selected as control group.The best-corrected visual acuity(BCVA),AL,spherical equivalent(SE),and optical coherence tomography angiography(OCT A)examination were performed in all the subjects.OCTA examination was used to measure the vascular density of the superficial retinal capillary plexus(SCP),deep retinal capillary plexus(DCP),and radial peripapillary capillary(RPC),as well as central macular thickness(CMT),and the area and volume of the foveal avascular zone(FAZ)of the subjects in two groups.The differences in these parameters of the subjects between two groups were analyzed.The AL of the subjects in two groups was measured using a biometer,and its correlations with the parameters mentioned above were evaluated.Results:No statistically significant differences were observed in age or sex distribution between two groups(P＞0.05).Compared with control group,both SCP and DCP vessel densities acrossing the whole(excluding the foveal),parafoveal,and perifoveal regions of the macular retina of the patients in case group were significantly decreased(P＜0.05).Compared with control group,the RPC vessel densities in the optic disc region of the patients in case group were significantly decreased in the whole,peripapillary,peripapillary superior,and peripapillary inferior sectors(P＜0.001),while the RPC vessel density was increased inside the disc(P＜0.01).Compared with control group,the whole FAZ volume of the patients in case group was increased(P＜0.01),while the parafoveal and perifoveal CMT were decreased(P＜0.001).In case group,AL was negatively correlated with SCP vessel density(r=-0.642,P＜0.001),DCP vessel density(r=-0.388,P＜0.001),RPC vessel density(r=-0.639,P＜0.001),and CMT(r=-0.495,P＜0.001),but positively correlated with FAZ volume(r=0.580,P＜0.001);no significant correlation was found between AL and FAZ area(r=-0.062,P=0.587).Conclusion:The patients with HM may exhibit early reductions in SCP,DCP,and RPC vessel densities,thinning of the central retina,and increased FAZ volume.Furthermore,as AL increases,SCP,DCP,and RPC vessel densitiesas as well as CMT decreases,while FAZ volume increases,suggesting significant associations between AL and the parameters mentioned above.

Sonodynamic therapy (SDT) can potentially induce immunogenic cell death in tumor cells, leading to the release of ATP, and facilitating the initiation of an immune response. Nevertheless, the enzymes CD39 and CD73 can swiftly convert ATP into immunosuppressive adenosine (ADO), resulting in an immunosuppressive tumor microenvironment (TME). This study introduced a nanomedicine (QD/POM1@NP@M) engineered to reprogram TME by modulating the CD39/CD73/ADO pathway. The nanomedicine encapsulated sonosensitizers silver sulfide quantum dots, and the CD39 inhibitor POM1, while also incorporating homologous tumor cell membranes to enhance targeting capabilities. This integrated approach, on the one hand, stimulates the release of ATP via SDT, thereby initiating the immune response. In addition, it reduced the accumulation of ADO by inhibiting CD39 activity, which ameliorated the immunosuppressive TME. Upon administration, the nanomedicine demonstrated substantial anti-tumor efficacy by facilitating the infiltration of anti-tumor immune cells, while reducing the immunosuppressive cells. This modulation effectively transformed the TME from an immunologically "cold" state to a "hot" state. Furthermore, combined with the checkpoint inhibitor α-PDL1, the nanomedicine augmented systemic anti-tumor immunity and promoted the establishment of long-term immune memory. This study provides an innovative strategy for combining non-invasive SDT and ATP-driven immunotherapy, offering new ideas for future cancer treatment.

Ovarian cancer is the most lethal malignancy affecting the female reproductive system. Pharmacological inhibitors targeting CDK4/6 have demonstrated promising efficacy across various cancer types. However, their clinical benefits in ovarian cancer patients fall short of expectations, with only a subset of patients experiencing these advantageous effects. This study aims to provide further clinical and biological evidence for antineoplastic effects of a CDK4/6 inhibitor (TQB4616) in ovarian cancer and explore underlying mechanisms involved. Patient-derived ovarian cancer organoid models were established to evaluate the effectiveness of TQB3616. Potential key genes related to TQB3616 sensitivity were identified through RNA-seq analysis, and TRIM4 was selected as a candidate gene for further investigation. Subsequently, co-immunoprecipitation and GST pull-down assays confirmed that TRIM4 binds to hnRNPDL and promotes its ubiquitination through RING and B-box domains. RIP assay demonstrated that hnRNPDL binded to CDKN2C isoform 2 and suppressed its expression by alternative splicing. Finally, in vivo studies confirmed that the addition of siTRIM4 significantly improved the effectiveness of TQB3616. Overall, our findings suggest that TRIM4 modulates ubiquitin-mediated degradation of hnRNPDL and weakens sensitivity to CDK4/6 inhibitors in ovarian cancer treatment. TRIM4 may serve as a valuable biomarker for predicting sensitivity to CDK4/6 inhibitors in ovarian cancer.

Polycystic ovary syndrome (PCOS) is the predominant cause of subfertility in reproductive-aged women; however, its pathophysiology remains unknown. Neurotensin (NTS) is a member of the gut-brain peptide family and is involved in ovulation; its relationship with PCOS is unclear. Here, we found that NTS expression in ovarian granulosa cells and follicular fluids was markedly decreased in patients with PCOS. In the in vitro culture of cumulus-oocyte complexes, the neurotensin receptor 1 (NTSR1) antagonist SR48692 blocked cumulus expansion and oocyte meiotic maturation by inhibiting metabolic cooperation and damaging the mitochondrial structure in oocytes and surrounding cumulus cells. Furthermore, the ERK1/2-early growth response 1 pathway was found to be a key downstream mediator of NTS/NTSR1 in the ovulatory process. Animal studies showed that in vivo injection of SR48692 in mice reduced ovulation efficiency and contributed to irregular estrus cycles and polycystic ovary morphology. By contrast, NTS partially ameliorated the ovarian abnormalities in mice with dehydroepiandrosterone-induced PCOS. Our findings highlighted the critical role of NTS reduction and consequent abnormal NTSR1 signaling in the ovulatory dysfunction of PCOS, suggesting a potential strategy for PCOS treatment.

To promote the standardization and normalization of perioperative care for follicular unit extraction(FUE) hair transplantation, ensure treatment efficacy, and align with advancements in the specialty, the Nursing Branch of the Chinese Association of Plastic and Aesthetics organized a panel of domestic experts. By integrating evidence-based medicine with clinical practice experience, and following thorough discussions, these experts developed the Clinical Practice Expert Consensus on Perioperative Nursing Care for Follicular Unit Extraction (2025). This consensus provides a comprehensive overview of hair transplantation, covering preoperative preparation, surgical procedures, intraoperative coordination, postoperative management, and complication prevention and treatment. It serves as a key reference and guide for implementing standardized perioperative nursing care in FUE hair transplantation.

TCM believes that the main pathogenesis of gastrointestinal dysfunction (GD) after laparoscopic cholecystectomy (LC) is spleen and stomach weakness, liver and stomach disharmony, liver depression and spleen deficiency, and intestinal depression. Moxibustion in the treatment of GD after LC can avoid the aggravation of gastrointestinal burden caused by oral drugs. The intervention methods mainly include suspension moxibustion, umbilical moxibustion, heat sensitive moxibustion, thunder fire moxibustion, warm acupuncture, partition moxibustion, etc. Moxibustion is often performed on the acupoints in liver meridian, spleen meridian, stomach meridian, small intestine meridian, large intestine meridian and Conception Vessel, such as Taichong (LR3), Ganshu (BL18), Yinlingquan (SP9), Zusanli (ST36), Tianshu (ST25), Wangu (SI4), Hegu (LI4), Zhongwan (CV12), Shenque (CV8) and Qihai (CV6). At present, most studies combined with moxibustion on the basis of conventional Western medicine treatment can significantly improve the efficacy, and have certain advantages in improving gastrointestinal motility decline, intestinal flora imbalance, first exhaust time, gastrointestinal hormone level disorder and intestinal mucosal barrier dysfunction. However, there are still some problems in the existing research: small sample size of clinical research, not perfect scoring scale, not unified treatment plan and operation standard, relatively scarce basic research, relatively simple acupoint research, lack of biochemical evaluation indicators, and the research of national moxibustion needs to be explored and improved in the future.

Objective:To explore the medication law of TCM external therapy for the treatment of diabetic foot using data mining methods.Methods:Literature on TCM external treatment for diabetic foot was retrieved from CNKI, Wanfang Data, and Chongqing VIP from the establishment of the databases to June 30, 2024. Excel 2019 software was used to conduct frequency statistics on drug frequency, properties, tastes and meridian tropism, drug efficacy, and commonly used drug pairs. Ancient and Modern Medical Cases Cloud Platform V3.5 was used for association rules, and SPSS Statistics 27.0 was used for complex network analyses.Results:A total of 425 articles were included, involving 328 prescriptions and 232 drugs. The drugs with higher frequency were Carthami Flos, Angelicae Sinensis Radix, Cinnamomi Ramulus, Olibanum, etc. The main tastes were pungent, bitter, and sweet; the main properties were cold and warm; the main meridians were heart, spleen, and liver meridians. The main efficacy was promoting blood circulation and removing blood stasis, clearing heat, and tonifying deficiency; association rule analysis obtained 20 commonly used drug pairs; clustering analysis resulted in four core drug combinations; complex network analysis led to one core prescription.Conclusions:TCM external therapy for diabetic foot follows the guiding principles of "promoting blood circulation and unblocking collaterals, tonifying deficiency and clearing heat" with coordinated regulation of the "heart-liver-spleen meridians". The core prescription and stage-specific formulation strategies reflect a trinity diagnostic and therapeutic approach of "disease differentiation-syndrome differentiation-stage differentiation", providing valuable reference and insights for clinical prescription practices.

Objective To explore the effect of urine mixing degree on 24-hour urinary total protein(24 h UTP)in patients with chronic kidney disease(CKD).Methods From October 1,2023 to December 31,2023,30 hospitalized patients who needed to complete 24 h UTP testing in Zhongshan Hospital,Fudan University were selected.A 5 L unified container was used to collect urine for 24 hours.After collection and one hour's standing,the urine sample was divided into upper,middle,and lower equal parts according to volume,which was defined as direct-sampling group.Then,the urine samples were fully mixed with a magnetic stirrer and sampled again according to the above-mentioned three-equal sampling method,which was defined as mixed-sampling group.The generalized estimating equation was used to compare the urinary protein concentration before and after mixing and at different sampling location.Results The results of generalized estimating equation showed that after controlling the variable"sampling position",there was no significant difference in urinary protein concentration between the direct-sampling group and the mixed-sampling group.After controlling the variable"mixing method",there was still no significant difference in urinary protein concentration at different sampling positions.After adjusting the covariates such as age,gender,and estimated glomerular filtration rate(eGFR),the results were consistent.Conclusions With standard protocol,the entire 24-hour urine sample is a relatively even-distributed solution.After the total urine collection is completed,the temporary sample can be directly extracted from any level of the original urine within 1 hour,and the urine protein concentration of the sample multiplied by the urine volume can reflect the 24 h UTR.

AIM: To investigate the acute clinical manifestations of cosmetology-related ocular damage(COD).METHODS:Retrospective study. A total of 53 cases(89 eyes)with ocular damage caused by cosmetology from April 2016 to October 2021 were collected. The clinical features were analyzed, including age, gender, affected eye(s), clinical manifestations, injury cause, treatment procedures, and prognosis.RESULTS: All 53 patients were female, aged 22-45 years, with an average age of 28.4±6.7 years. Monocular injuries were observed in 17 patients, and binocular injuries in 36 patients. The same eye could exhibit two or more ocular damage simultaneously. The primary cosmetology procedures causing COD were eyeliner tattooing(38 eyes; 43%), eyelash extensions(18 eyes; 20%), removal of false eyelashes(11 eyes; 12%), mascara application(8 eyes; 9%), double eyelid surgery(6 eyes; 7%), and others(8 eyes; 9%). Major ocular damages included corneal damage(56 eyes; 63%), eyelid contact dermatitis(26 eyes; 29%), conjunctivitis(19 eyes; 21%), reactive eyelid edema(13 eyes; 15%), ocular surface foreign bodies(12 eyes; 14%), bacterial infection of the palpebral margin(10 eyes; 11%), and others(5 eyes; 6%). These 5 eyes included 1 eye(1%)with central retinal artery occlusion caused by periocular injection of hyaluronic acid. The majority of patients(74 eyes)recovered within 1-2 wk with appropriate treatment, while filamentosa keratitis appeared in 3 eyes and the eye with central retinal artery occlusion had poor prognosis.CONCLUSIONS: COD predominantly occurs in young and middle-aged females with cosmetology experience. The most common cosmetology procedure leading to COD is eyeliner tattooing, and corneal damage is the most significant type of COD. COD can be effectively prevented and treated, resulting in a generally favorable prognosis.
