OBJECTIVE: The present study evaluated the effects of deep acupuncture at Weizhong acupoint (BL40) on bladder function and brain activity in a rat model of overactive bladder (OAB), and investigated the possible mechanisms around the acupuncture area that initiate the effects of acupuncture. METHODS: Adult female Sprague-Dawley rats were randomly divided into six groups, comprising a control group, model group, group treated with deep acupuncture at BL40, group treated with shallow acupuncture at BL40, group treated with acupuncture at non-acupoint next to BL40, and group treated with acupuncture at Xuanzhong (GB39). Urodynamic evaluation was used to observe the urination, and functional magnetic resonance imaging was used to observe the brain activation. The mechanism of acupuncture at BL40 in regulating bladder function was explored by toluidine blue staining and enzyme-linked immunosorbent assay, and the mechanism was verified by stabilizing mast cells (MCs) or blocking tibial nerve. RESULTS: Deep acupuncture at BL40 significantly increased the intercontraction interval in OAB rats and enhanced the mean amplitude of low frequency fluctuation of primary motor cortex (M1), periaquaductal gray matter (PAG), and pontine micturition center (PMC). It also increased the zero-lag functional connectivity between M1 and PAG and between PAG and PMC. Shallow acupuncture at BL40 and acupuncture at non-acupoint or GB39 had no effect on these indexes. Further studies suggested that deep acupuncture at BL40 increased the number and degranulation rate of MCs as well as the contents of 5-hydroxytryptamine, substance P, and histamine in the tissues around BL40. Blocking the tibial nerve by lidocaine injection or inhibiting MC degranulation by sodium cromoglycate injection obstructed the effects of acupuncture on restoring urinary function and modulating brain activation in OAB rats. CONCLUSION Deep acupuncture at BL40 may be more effective for inhibiting OAB by promoting degranulation of MCs around the acupoint and stimulating tibial nerve, thereby regulating the activation of the brain area that controls the lower urinary tract.

OBJECTIVES: To explore the mediating role of sleep duration in the relationship between depression symptoms and myopia among middle school students. METHODS: This study was a cross-sectional research conducted using a stratified cluster random sampling method. A total of 1 728 middle school students were selected from two junior high schools and two senior high schools in certain urban areas and farms of the Xinjiang Production and Construction Corps. Questionnaire surveys and vision tests were conducted among the students. Spearman analysis was used to analyze the correlation between depression symptoms, sleep duration, and myopia. The Bootstrap method was employed to investigate the mediating effect of sleep duration between depression symptoms and myopia. RESULTS: The prevalence of myopia in the overall population was 74.02% (1 279/1 728), with an average sleep duration of (7.6±1.0) hours. The rate of insufficient sleep was 83.62% (1 445/1 728), and the proportion of students exhibiting depression symptoms was 25.29% (437/1 728). Correlation analysis showed significant negative correlations between visual acuity in both eyes and sleep duration with depressive emotions as measured by the Center for Epidemiologic Studies Depression Scale (with correlation coefficients of -0.064, -0.084, and -0.199 respectively; P<0.01), as well as with somatic symptoms and activities (with correlation coefficients of -0.104, -0.124, and -0.233 respectively; P<0.01) and interpersonal relationships (with correlation coefficients of -0.052, -0.059, and -0.071 respectively; P<0.05). The correlation coefficients for left and right eye visual acuity and sleep duration were 0.206 and 0.211 respectively (P<0.001). Sleep duration exhibited a mediating effect between depression symptoms and myopia (indirect effect=0.056, 95%CI: 0.029-0.088), with the mediating effect value for females (indirect effect=0.066, 95%CI: 0.024-0.119) being higher than that for males (indirect effect=0.042, 95%CI: 0.011-0.081). CONCLUSIONS Sleep duration serves as a partial mediator between depression symptoms and myopia in middle school students.

Objective:To evaluate the long-term efficacy and safety of recombinant coagulation factor Ⅷ (Octocog alfa) in Chinese patients with hemophilia A (HA) enrolled in the International Antihemophilic Factor Hemophilia A Outcome Database (AHEAD) study (NCT02078427) .Methods:Enrollment of Chinese patients in the AHEAD study was completed by January 2021, and data were collected up to July 15, 2022. This study primarily assessed patients in terms of the Gilbert score, global gait score within the Hemophilia Joint Health Score (HJHS), annualized bleeding rate (ABR), annualized joint bleeding rate, and adverse events.Results:A total of 168 male patients were included in this study, of which 113 received prophylactic treatment and 53 received on-demand treatment. The average age of the patients was 21.4±13.37 years. Compared with baseline, the global gait score within HJHS significantly decreased during the 1-year follow-up in patients with moderately severe HA in the prophylactic treatment group ( P=0.01) and on-demand treatment group ( P=0.008). The mean reduction in Gilbert score was greater in the prophylactic treatment group than in the on-demand treatment group (28.6% vs 8.2%). The average ABR decreased significantly during the 1-year follow-up (3.70 vs 7.78, P=0.01) in the prophylactic treatment group, particularly in patients with severe HA (2.14 vs 8.98, P=0.006) and pediatric patients (2.1 vs 4.73, P=0.03). The ABR score also decreased significantly in the moderate-dose prophylactic treatment group ( P=0.015). During the 1-year follow-up, 25 patients (14.9%) reported 39 adverse events, with only one patient developing treatment-related F Ⅷ inhibitor. Conclusion:Joint mobility improved in patients receiving either prophylactic or on-demand Octocog alfa. Bleeding episodes significantly reduced in patients receiving prophylactic treatment, particularly in pediatric patients and those with severe HA.

Objective:To analyze the clinical features and genetic sequencing results of a patient with Kallmann syndrome(KS) carrying digenic mutations who initially presented with osteoporosis, and to enhance awareness of this disease phenotype.Methods:Clinical data were collected, and peripheral blood DNA was extracted for whole-exome sequencing. Relevant literature was reviewed to summarize phenotypes associated with digenic/oligogenic variants involving CHD7.Results:The patient exhibited back pain, delayed development of secondary sexual characteristics, and hyposmia. Laboratory tests revealed reduced sex hormones and gonadotropin levels, while pituitary imaging was unremarkable. Bone mineral density imaging confirmed osteoporosis, and thoracolumbar X-rays showed multiple vertebral compression fractures. Genetic analysis identified a heterozygous splice-site mutation in CHD7(c.2698-1G>T) and a heterozygous missense mutation in WDR11(c.439G>A: p.D147N). According to ACMG criteria, the CHD7 mutation was classified as pathogenic, while the WDR11 variant was defined as a variant of uncertain significance(VUS). Literature review indicated that 40% of KS patients with digenic/oligogenic variants involving CHD7 presented with hearing or ocular abnormalities.Conclusion:This study reports a novel CHD7 mutation and a previously undescribed digenic combination of CHD7 and WDR11 variants in a KS patient. CHD7 variants may be implicated in auditory or ocular involvement in KS cases with digenic/oligogenic inheritances. KS patients may also manifest skeletal abnormalities in addition to hypogonadotropic hypogonadism. Tailored management of sex hormones and osteoporosis therapies across life stages is essential for optimizing bone health in KS.

Objective To investigate the clinical characteristics of women with abnormal uterine bleeding(AUB)in sub-plateau regions and analyze the factors affecting their treatment methods.Methods AUB patients who were hospitalized from Jan 1,2018 to Dec 31,2022,in a sub-plateau region(Yongping County People's Hospital of Yunnan Province)with an average altitude of 1 620 meters were selected.The general clinical characteristics of the patients were summarized,and patients were classified into two categories(with or without uterine structural lesion)and nine subtypes(PALM-COEIN)according to the FIGO recommended etiological classification guidelines.Then the patients were divided into groups based on the presence or absence of uterine structural lesions,ethnic group(Han and minority),conservative drug treatment and surgical treatment groups,blood transfusion and non-blood transfusion groups.Binary Logistic regression analysis was used to identify factors affecting treatment methods.Results A total of 481 AUB patients enrolled,and the delayed consultation rate was as high as 80.46%,and the proportion of overweight and obese patients was 49.90%,which was higher than the average level among Chinese women.The main cause was AUB-O(AUB-ovulatory dysfunction),accounting for 78.59%of cases,the proportion of patients with delayed medical treatment was higher than those without delayed medical treatment(82.17%vs.74.47%).Patients who received blood transfusion were significantly younger,had lower hemoglobin(HGB)levels,fewer pregnancies,and lower BMI compared to those in the non-blood transfusion group(P<0.05).Univariate analysis showed that the surgical treatment group had older age,longer onset time,higher HGB levels,more pregnancies and deliveries,higher BMI,a higher proportion of Han ethnicity patients,lower rates of non-blood transfusion,higher rates of hypertension,and more uterine structural lesions compared to the conservative drug treatment group.Multivariate regression analysis revealed that blood transfusion treatment reduced the probability of surgical treatment.Age and uterine structural lesions were risk factors for requiring surgical treatment,for each additional year of age,the risk of undergoing surgical treatment increased by 10%.The risk of requiring surgical treatment for patients with uterine structural lesions was 2.987 times higher than for those without.Conclusion AUB patients in this sub-plateau regions have a high rate of delayed consultation and a high proportion of overweight and obesity,with AUB-O being the primary cause.Older age and the presence of uterine structural lesions were risk factors for requiring surgical treatment.

Objective To understand the current situation of healthcare-associated infection(HAI)in China,pro-vide data support and decision-making basis for formulating scientific and effective strategies for HAI prevention and control.Methods A nationwide cross-sectional survey on HAI was conducted among various types and levels of medical institutions in China according to a unified protocol of bedside surveys and case investigations.Results In 2024,a total of 5 736 medical institutions and 2 751 765 patients were surveyed.Among them,34 889 HAI cases were identified,with a prevalence rate of 1.27％.The number of HAI episodes was 38 032,and case prevalence rate was 1.38％.The prevalence rate of HAI in medical institutions in different regions of China ranged from 0.66％to 2.35％.Among medical institutions of different scales,those with a bed capacity of ≥900 had the high-est incidence of HAI,reaching 1.65％.The most common infection site was the lower respiratory tract(44.66％),followed by the urinary tract(12.94％),surgical site(9.32％),upper respiratory tract(7.02％),and bloodstream infection(5.78％).The top 3 departments with the highest HAI rates were the general intensive care unit(10.02％),department of neurosurgery(5.51％),and department(group)of hematology(5.34％).A total of 23 238 strains of HAI pathogens were detected,with 10 714 strains(46.10％)from lower respiratory tract speci-mens.The top 5 detected strains were Klebsiella pneumoniae(14.76％),Pseudomonas aeruginosa(13.33％),Escherichia coli(12.79％),Acinetobacter baumannii(9.23％),and Staphylococcus aureus(7.88％).231 944 pa-tients underwent class Ⅰ incision surgery were monitored,with 1 647 cases experienced surgical site infection,and the prevalence rate of surgical site infection was 0.71％.The number of patients who should undergo pathogen de-tection(patients receiving therapeutic and therapeutic combined prophylactic antimicrobial agents)was 715 179,while the actual number was 480 492,with a pathogen detection rate of 67.18％.425 225 patients received patho-genic detection before treatment,with a detection rate of 59.46％.Conclusion The overall HAI prevalence in Chi-na is lower,showing disparities among medical institutions of different regions and scales.Therefore,precise imple-mentation of measures is necessary for HAI prevention and control,with a focus on high-risk institutions and high-risk departments,key areas,and critical procedures.All levels of medical institutions should continuously reduce the incidence of HAI by strengthening monitoring,standardizing the use of antimicrobial agents,and reinforcing basic HAI prevention and control measures.

Objective To investigate the dynamic characteristics of intestinal pathological development at different time points in a mouse model of colitis-associated colon cancer.Methods A colitis-cancer model was established in C57BL/6 mice using azoxymethane(AOM)combined with dextran sulfate sodium(DSS).Samples were collected at 7,10,and 14 weeks post-modeling and the spleen index,colon length,mass,and colon mass per unit length were measured.Histopathological changes in the colon were observed by hematoxylin and eosin and Masson staining.Expression levels of the cancer stem cell marker CD44 and Wnt signaling pathway genes Wnt2b,Lrp5,Axin2,and Znrf3 at different pathological stages were detected by reverse transcription quantitative real time PCR.Cancer-associated fibroblasts(FAP),CD44,the proliferation marker Ki67,and goblet cell MUC2 protein were detected by multiple immunofluorescence histochemistry(mIHC)and immunofluorescence.In addition,colon organoids were isolated from model mice at ten and fourteen weeks and cultured in vitro to observe changes in organoid morphology and marker expression.Results AOM/DSS-induced mice showed reduced,distorted,and branched colon crypt structures with a few collagen fibers at 7 weeks,and varying degrees of colon intraepithelial neoplasia,with an increased proportion of high-grade intraepithelial neoplasia over time and increased collagen fiber staining at ten and fourteen weeks.mRNA levels of CD44 and Wnt2b in the colon were significantly increased(P＜0.05)and Axin2 was decreased(P＜0.01)in model mice compared with control mice at fourteen week,and levels of Wnt2b,Lrp5,and Znrf3 were increased compared with seven-week mice(P＜0.01,P＜0.05,P＜0.01),and Axin2 was decreased(P＜0.01).mIHC staining showed increased expression of FAP and CD44 in the colon in model mice at ten and fourteen weeks,with decreased MUC2 expression.Colon organoids showed cystic dilation,especially at fourteen weeks,with more prominent expression of Ki67 and CD44.Conclusions The AOM/DSS-induced mouse model exhibited chronic colonic inflammation,low-grade intraepithelial neoplasia,and high-grade intraepithelial neoplasia at seven,ten,and fourteen weeks,respectively.The pathological microenvironment was characterized by fibroblast activation and abnormal proliferation of epithelial cells.

AIM:The study aims to investigate the effects of Huayu-Qutan formula(HYQT)-medicated serum on oleic acid-induced lipid damage and endoplasmic reticulum stress(ERS)in HepG2 cells,and to explore the mecha-nism underlying the prevention and treatment of lipid metabolism disorders by HYQT.METHODS:The HepG2 cells were treated with various concentrations of oleic acid,and CCK8 assay,oil red O staining and ELISA were used to identify the optimal treatment concentration and time of oleic acid and HYQT-medicated serum.Moreover,the cells were divided into control,model,thapsigargin(Tg),and Tg+HYQT groups.Cellular lipid deposition was measured using oil red O staining,while triglyceride(TG)and free fatty acid(FFA)levels were assessed by ELISA.Transmission electron micros-copy was used to examine endoplasmic reticulum structures,and RT-qPCR and Wes fully automated protein quantification analysis system were used to measure the mRNA and protein expression of glucose-regulated protein 78(GRP78),sterol regulatory element binding protein 1c(SREBP1c),acetyl coenzyme A carboxylase(ACC1),fatty acid synthase(FAS)and stearoyl coenzyme A desaturase 1(SCD1)in different groups.RESULTS:Significant lipid deposition was induced in HepG2 cells after treatment with 1 000 μmol/L oleic acid,while treatment with serum containing 10%HYQT for 48 h was found to be optimal.Compared with control group,the cells in model group showed significant deposition of oil red O-stained lipid droplets in the cytoplasm,associated with endoplasmic reticulum expansion,ERS,and nuclear condensa-tion.The TG and FFA levels,and the mRNA and protein expression levels of GRP78,SREBP1c,ACC1,FAS and SCD1 were increased significantly(P<0.01).Compared with model group,the cells treated with HYQT-mediated serum showed marked decrease in the number of lipid droplets in the cytoplasm,with restored endoplasmic reticulum morphology.The TG and FFA levels were significantly reduced(P<0.01),and the mRNA and protein levels of factors related to ERS and de novo fatty acid synthesis were markedly decreased(P<0.01).Treatment with Tg,an ERS agonist,led to greater accu-mulation of cytoplasmic lipid droplets and increased endoplasmic reticulum expansion.Marked variations in the morpholo-gy and size of the endoplasmic reticulum were observed,with fusion and clustering of vacuoles.The TG and FFA levels,and the expression of ERS-and fatty acid synthesis-related factors were increased(P<0.01).Compared with Tg group,the cells treated with Tg+HYQT showed reduced number of cytoplasmic lipid droplets,attenuated endoplasmic reticulum dilation,and decreased number and volume of vacuoles,while the TG and FFA levels and the expression of ERS-and fatty acid synthesis-associated factors were significantly decreased(P<0.01).CONCLUSION:Serum containing HYQT alle-viates oleic acid-induced lipid damage in HepG2 cells by inhibiting ERS-induced de novo synthesis of fatty acids.

Objective:To investigate the status of dignity impairment in elderly incontinence-related dermatitis patients, and to systematically analyze the influencing factors in order to provide reference opinions for the formulation of medical strategies by clinical medical staff.Methods:Using the cross-sectional survey method, from April 15 to April 30, 2024, aged incontinence-related dermatitis patients were selected from 37 tertiary comprehensive hospitals in 10 provinces and municipalities, including Zhejiang Province, Sichuan Province, Guangdong Province, etc. by convenient sampling method. The general data questionnaire and Patient Dignity Inventory were used to investigate their current situation.Results:A total of 315 questionnaires were collected, 307 were valid, and the effective rate was 97.5%. Among 307 cases, 146 cases were males, 161 cases were females, aged (71.46 ± 9.35) years old. The incidence of impaired dignity in elderly patients with incontinence-related dermatitis was 49.5%(152/307). The average score of Patient Dignity Inventory was (45.50 ± 20.17). The results of multivariate regression analysis showed that farming ( OR = 2.405, 95% CI 1.108-5.217), individual industrial and commercial households ( OR = 5.680, 95% CI 2.504-12.888), the primary disease were respiratory diseases ( OR = 2.716, 95% CI 1.018-7.246) and nervous system diseases ( OR = 6.117, 95% CI 2.572-14.551) were risk factors for impaired dignity in elderly incontinence-related dermatitis (both P<0.05). Not living alone ( OR = 0.381, 95% CI 0.184-0.790) and self-rated family relationship harmony ( OR = 0.630, 95% CI 0.449-0.882) were protective factors for dignity impairment in elderly incontinence-related dermatitis patients (both P<0.05). Conclusions:There are many factors that affect the dignity of patients with incontinence-related dermatitis in the elderly, and medical staff should comprehensively consider a variety of factors and establish and improve a prevention and management mechanism suitable for the dignity of patients with incontinency-related dermatitis in the elderly.
