Objective: To explore the association between mental health and muscle strength among Chinese adolescents aged 13- 18, providing a theoretical foundation and intervention strategies for mental health promotion. Methods: Data were obtained from the 2019 Chinese National Survey on Students Constitution and Health, including 98 631 Chinese adolescents aged 13- 18. Psychological distress was assessed by using the Kessler Psychological Distress Scale (K10), and mental well being was measured with the Warwick-Edinburgh Mental Well being Scale (WEMWBS). Based on the gender and age specific Z scores of various test items [grip strength, standing long jump, pull ups (for males), and sit ups (for females)], muscle strength index (MSI) was constructed to evaluate the comprehensive level of muscle strength in adolescents. According to the Dual factor Model (DFM) of mental health, participants were categorized into four groups:troubled, symptomatic but content, vulnerable, and complete mental health. Gender differences were analyzed by using Chi-square tests, trends were tested with Cochran-Armitage tests, and multinomial Logistic regression models were applied to assess associations between muscle strength and mental health among adolescents. Results: In 2019, 37.4% of Chinese adolescents aged 13-18 were reported of high mental distress, and 59.9% were reported of low mental well being. Boys had significantly lower rates of high mental distress (35.3%) and low mental well being (55.6%) compared to girls (39.4%, 64.3%), and the differences were of statistical significance ( χ 2=176.13, 780.42, both P <0.05). In 2019, the rate of complete mental health among adolescents showed a downward trend with increasing age ( χ 2 trend = 258.47) and a gradual upward trend with increasing muscle strength levels ( χ 2 trend =123.14)，and both boys and girls exhibited similar trends ( χ 2 trend =103.83, 168.46; 57.00 , 67.34) (all P <0.05). The results of the unordered multiclass Logistic regression model showed that after controlling for confounding factors such as age and gender, when the completely pathological group as a reference, for every 1 unit increase in MSI in adolescents, the likelihood of being in a completely mental health state increased by 29% ( OR = 1.29); for every unit increase in the Z-score for pull ups, the likelihood of being in a completely mental health state increased by 6% ( OR =1.06) among boys; for every 1 unit increase in sit up Z score, the likelihood of being in a completely mental health state increased by 19% ( OR =1.19) among girls (all P <0.05). Conclusions The mental health status of Chinese adolescents is not good enough. Muscle strength is positively associated with mental health.

Objective: To investigate the clinical characteristics, diagnostic approach, and multidisciplinary treatment strategy for a rare case of congenital defect presenting as a complex of hemifacial microsomia with cardiac and spinal deformities, in order to provide a reference for the clinical management of such cases Methods : The clinical data of a 9-year-old patient with hemifacial microsomia (HFM) complicated by post-operative Tetralogy of Fallot and scoliosis were retrospectively analyzed. A definitive diagnosis was established through specialized examinations, imaging studies, bone age assessment, and intellectual evaluation. The patient presented with right-sided HFM (with 3 accessory auricles, a transverse facial cleft, a microform median cleft of the upper lip, hypoplasia of the mandible and facial soft tissues, and agenesis of the right parotid gland and coronoid process), increased orbital distance, dental malalignment, congenital absence of one lateral incisor, and rampant caries in both primary and permanent dentition. The patient had undergone open-heart surgery for Tetralogy of Fallot with a patent foramen ovale four years prior and also presented with scoliosis and systemic developmental delay (bone age approximately 7 years). A retrospective analysis of the diagnosis and treatment of this type of case was conducted in conjunction with a literature review. Results: A multi-disciplinary treatment (MDT) model was adopted. The patient first received treatment for dental caries, followed by excision of the right accessory auricles, repair of the transverse facial cleft, and correction of the microform upper lip cleft under general anesthesia. A 6-month follow-up showed significant improvement in facial appearance and good recovery of oral function. The literature review indicated that hemifacial microsomia is a congenital disease characterized by the hypoplasia of multiple tissue structures on one side of the face. Its etiology may be related to impaired blood supply to the first and second branchial arches during early pregnancy. It often affects the craniofacial bones, ears, and soft tissues, leading to functional impairments in respiration, feeding, speech, and hearing, as well as psychological issues, severely impacting the quality of life in serious cases. The combination with cardiac and spinal deformities is relatively rare and requires individualized sequential treatment plans based on clinical evaluation and surgical indications. This typically includes cardiac surgical correction, spinal orthopedics, early soft and hard tissue reconstruction (e.g., distraction osteogenesis, facial cleft repair, and accessory auricle excision), orthodontic and dental management during the growth period, and final facial contouring in adulthood. Conclusion HFM can be associated with cardiac and spinal deformities, presenting with complex clinical manifestations. Early diagnosis, MDT collaboration, and sequential treatment plans are key to improving patients’ prognosis and quality of life.

Objective: To explore the correlation and lag effects of environmental factors on pediatric respiratory disease visits at hospital, so as to provide scientific basis for disease prediction and optimizing clinical diagnosis and treatment. Methods: Data from 503 889 pediatric respiratory disease outpatient and emergency visits a central hospital in Minhang District of Shanghai between 2017 and 2019, along with concurrent meteorological data were collected. A distributed lag non-linear models (DLNM) was constructed to explore the specific relationship between pediatric respiratory disease consultations and various environmental factors and to quantify the cumulative lag effects of environmental factors on respiratory disease consultations. Results: Among the environmental factors, temperature, fine particulate matter (PM 2.5 ), inhalable particulate matter (PM 10 ), nitrogen dioxide (NO 2), and sulfur dioxide (SO 2) were associated with pediatric respiratory disease visits. After adjusting for temperature, PM 2.5 and PM 10 concentrations did not show significant immediate or lag effects. The relative risk (RR) of pediatric respiratory disease visits increased with rising NO 2 concentrations. When NO 2 concentration ≥55 μg/m 3, significant immediate and lagged effects (lag 3, 5, and 7 days) were observed. The RR values were 1.05, 1.13, 1.17, and 1.21( P <0.05). The RR values showed an inverted “U” shaped relationship with SO 2 concentrations. When SO 2 concentration ≥5 μg/m 3, significant lagged effects (lag 3, 5, and 7 days) were observed. The RR values were 1.03 , 1.03, and 1.04 ( P <0.05). Conclusion High concentrations of NO 2 and SO 2 increase the risk of pediatric respiratory disease visits, with observable lag effects.

Objective:To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for the treatment of ileocecal valve lipoma.Methods:A retrospective cohort study was performed on data of ileocecal lipoma patients who underwent ESD at the Endoscopy Center of Zhongshan Hospital, Fudan University from December 2013 to June 2023. According to the lesion location, the patients were divided into ileocecal valve group and cecum group. The operation time, operation speed, en bloc resection rate, complications, and follow-up outcomes between the two groups were compared.Results:A total of 59 patients with ileocecal lipoma were enrolled, including 31 patients in the ileocecal valve group and 28 patients in the cecum group.There were no significant differences in gender, age, specimen size, or lesion size between the two groups ( P>0.05). Lipomas in both the ileocecal valve group and the cecum group were successfully resected by ESD. The en bloc resection rates were 100.0% (31/31) and 92.9% (26/28) respectively, and the difference was not statistically significant ( χ2=0.033, P=0.133). Median operative duration significantly differed between the two groups ( ileocecal valve group 26 min VS cecum group 20 min, Z=-0.136, P=0.027), as did resection speed (ileocecal valve group 0.14 cm2/min VS cecum group 0.24 cm2/min, Z=-0.223, P=0.022). Adverse events included one postoperative fever in the ileocecal valve group and one delayed bleeding in the cecum group. During the median follow-up of 38 months (7-106 months), there was no case of residual tumor or recurrence. Conclusion:Despite technical challenges in ESD of ileocecal valve lipoma, it is still a safe, feasible and effective treatment method.

Objective To explore the prognostic value of plasma sST2 in the population of coronary heart disease(CHD)complicated with chronic kidney disease(CKD).Methods A total of 326 elderly patients with CHD or CKD undergoing physical examination in the Second Medical Center of Chinese PLA General Hospital from April 2021 to July 2022 were continuously enrolled,and according to whether having CHD or CKD,they were divided into a CHD-CKD comorbidity group(n=117),a CHD group(n=124),and a CKD group(n=85).Their baseline data were compared,and the plasma concentration of sST2 was detected using chemiluminescence assay.Multiple linear regression analysis was used to identify the relevant factors of sST2.Kaplan-Meier survival curve and Cox proportional hazards regression analyses were applied to determine the impact of plasma sST2 on all-cause mortality and major adverse cardiovascular events(MACE).Results There were significant differences among the three groups in terms of age,sST2 and NT-proBNP levels,Log(NT-proBNP),eGFR,ratios of hyperuricemia,cerebral infarction,tumors,and using anti-platelet drugs and statins,PR interval,LVEF,and TC,TG,HDL-C and Hb levels(P＜0.05,P＜0.01).Multiple linear regression analysis showed that the sST2 level was positively correlated with logNT-proBNP and negatively with Hb level in the comorbidity group(t=2.266,P=0.025;t=-2.235,P=0.021).Kaplan-Meier survival curve analysis indicated that during a median fol-low-up of 31.5(22.0,32.2)months,the comorbidity group had a lower survival rate than the two single-disease groups(P＜0.05,P＜0.01),and higher incidence of MACEs than the CKD group(P＜0.01).ROC curve analysis suggests that the AUC value of sST2 in predicting all-cause mor-tality in the comorbid group was 0.692.Cox proportional hazards regression model revealed that after adjustment for cofounders,sST2 was still an independent risk factor for all-cause mortality in the comorbid patients(HR=4.461,95％CI:1.640-8.399,P=0.024),although this prognos-tic value may be influenced by NT-proBNP.Conclusion sST2 can independently predict the risk of mortality in elderly patients with CHD-CKD comorbidity.

Objective To investigate the relationship between serum soluble suppression of tumori-genicity 2(sST2)and cardiac diastolic function in elderly patients with coronary heart disease(CHD)and chronic kidney disease(CKD).Methods A total of 116 elderly CHD patients suffer-ing from CKD taking physical examinations at the Second Medical Center of Chinese PLA General Hospital from April 2021 to July 2022 were recruited,and according to their serum sST2 level,they were divided into high sST2 group(＞28.65 μg/L,58 cases)and low sST2 group(≤28.65μg/L,58 cases).The baseline data of all subjected patients were collected,including N-terminal pro-B-type natriuretic peptide(NT-proBNP),as well as peak early diastolic mitral flow velocity(E),peak early diastolic mitral annular velocity(e'),isovolumetric relaxation time(IVRT)and some other indicators in echocardiography.Serum sST2 level was measured using chemilumines-cence assay.Pearson correlation analysis and multiple linear regression analysis were used for analysis.Results The high sST2 group had significantly larger proportion of diabetes and usingβ-blockers,higher levels of sST2,urea and logNT-proBNP,increased left ventricular mass index,thicker left ventricular posterior wall thickness,and elevated E/e'and IVRT,and lower levels of hemoglobin and triacylglycerol,and decreased e'value when compared with the low sST2 group(P＜0.05,P＜0.01).The correlation analysis showed that sST2 was positively correlated with taking β-blockers,urea and logNT-proBNP levels,and E/e'ratio(r=0.226,P=0.015;r=0.362,P=0.001;r=0.374,P=0.001;r=0.257,P=0.005),and negatively correlated with triglycerides,hemoglobin and e'value(r=-0.227,P=0.014;r=-0.314,P=0.001;r=-0.203,P=0.029).Multiple linear regression analysis displayed that sST2 was linearly correlated with triglycerides,urea and NT-proBNP levels,and E/e'(P＜0.05,P＜0.01).Conclusion Serum sST2 level is cor-related with cardiac diastolic function in elderly patients with comorbidities of CHD and CKD.

Objective To investigate the current status of adverse drug reaction(ADR)monitoring in medical institu-tions under China's pharmacovigilance framework in Guangdong Province,and to propose evidence-based strategies for enhancing institutional monitoring capabilities.Methods A cross-sectional survey was conducted using a structured questionnaire devel-oped in alignment with national regulatory requirements and expert consensus.Data were collected from 65 medical institutions,including general hospitals,traditional Chinese medicine hospitals,and maternal/children's hospitals,across 21 prefecture-level cities in Guangdong.Descriptive and comparative analyses were performed to evaluate institutional practices.Results All 65 in-stitutions submitted valid responses.Among them,63(96.9％)had established standardized ADR reporting protocols,with 93.8％(61/65)delegating oversight to pharmacy departments.ADR data were predominantly collected via institutional informa-tion systems(67.7％,44/65),though these systems focused on passive reporting and basic data aggregation,lacking functional-ities for active signal detection or risk alert mechanisms.Significant disparities(P＜0.05)were observed across hospitals of dif-ferent tiers in reporting modalities,system sophistication,analytical frequency,and early warning implementation.Notably,mo-nitoring practices for conditionally approved drugs(e.g.,emergency-authorized therapeutics)exhibited systemic deficiencies.Conclusions To address these gaps,the following measures are recommended:Accelerating the adoption of intelligent monito-ring systems to enable real-time ADR detection and predictive analytics;Implementing tiered resource allocation policies to ensure equitable capability development;Establishing specialized protocols for high-risk pharmaceuticals,particularly conditionally ap-proved and fast-tracked drugs;Strengthening interdisciplinary training programs to improve pharmacovigilance literacy among healthcare practitioners.These interventions aim to foster a proactive risk management culture and advance patient safety within China's evolving healthcare landscape.

Objective To analyze clinical characteristics and therapeutic strategies for patients with Trichosporon asahii(T.asahii)bloodstream infection(BSI),and provide reference for clinical diagnosis and treatment for such disease.Methods Diagnosis and treatment process of a patient with T.asahii BSI were reported.China National Knowledge Infrastructure(CNKI),Wanfang,PubMed,and Web of Science databases were retrieved using key-words:"Trichosporon asahii"and"bloodstream infection".Patients'age,gender,underlying diseases,immune status,treatment,and clinical outcome as well as antimicrobial susceptibility testing results of T.asahii were ana-lyzed retrospectively.Results The leukemia patient developed T.asahii BSI during chemotherapy,and showed clinical improvement after treatment with fluconazole+flucytosine.A total of 44 cases(43 from literature plus this index case)were analyzed.Among these cases,28 were males,the median age was 54.5 years old.The underlying diseases were predominantly hematological diseases.Catheter,urinary tract,and skin were identified as concurrent culture-positive sites.Azoles exhibited good antimicrobial activity in vitro,with voriconazole showing the strongest activity and associated with significantly higher survival rates.Under the guidance of antimicrobial susceptibility tes-ting results,patients with fluconazole treatment had a higher survival rate.At minimum inhibitory concentrations(MICs)of 4-8 μg/mL of fluconazole,fluconazole combined with other agents was predominantly required.Am-photericin B demonstrated good in vitro activity,but the overall survival rate of patients was low when amphotericin B was used as monotherapy without azoles.Catheters removal,surgical intervention,and neutrophil recovery were influencing factors for enhanced survival rates.Conclusion BSI caused by T.asahii primarily occurs in patients with hematological diseases,with neutropenia being a high-risk factor.Infection sites at catheter,urinary tract,and skin may be infection sources.Clearing the source of infection and promoting the recovery of neutrophils can help to improve survival rates of patients.For voriconazole-intolerant patients,fluconazole monotherapy or in combination with flucytosine/amphotericin B can be used alternatively based on antimicrobial susceptibility testing results.

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.

Objectives:To analyze the correlation between the the body shape index(ABSI)and all-cause mortality(ACM)as well as cardiovascular mortality(CVM)in patients with acute heart failure.Methods:This study analyzed data from the National Registration Study of Major Chronic Diseases,a prospective cohort on heart failure.A total of 4 907 patients with acute heart failure were enrolled from multiple centers nationwide,of which 4 375 were eligible for this study.The relationships of between body mass index(BMI),waist circumference,and ABSI with ACM and CVM were assessed using multivariable cox proportional hazards models.Results:The mean age of the patients was(65.0±13.4)years,62.3%was male.The median follow-up time was 4.6(4.59,4.65)years,there were 1 972(45.1%)ACM and 1 400(32.0%)CVM.Multivariable cox regression analysis showed that higher ABSI was associated with an increased risk of mortality.Compared to the second quartile of ABSI,the hazard ratio(HR)for the highest(fourth)quartile were 1.29(95%CI:1.14-1.46,P<0.05)for ACM and 1.23(95%CI:1.06-1.43,P<0.05)for CVM.In contrast,BMI and waist circumference were inversely associated with risks of both ACM and CVM.Conclusions:ABSI can more intuitively reflect the correlation between obesity and death in patients with heart failure than BMI and waist circumference,which has important clinical significance.
