Objective: To investigate the association of physical activity and screen time with overweight and obesity among children and adolescents with special needs in Tianjin, so as to provide scientific evidence for childhood obesity prevention and intervention measures in the population. Methods: From January 2022 to June 2024, 296 children and adolescents with intellectual disabilities and autism spectrum disorders aged 2-18 years were recruited from special education schools and institutions in Tianjin. Height and weight were measured, and a standardized questionnaire was used to assess physical activity and screen time. Binary Logistic regression analysis was carried out to investigate the association of physical activity and screen time with overweight and obesity. Results: The prevalence of overweight and obesity among children and adolescents with special needs in Tianjin were 17.2% and 21.6%, respectively, and the combined prevalence of overweight and obesity was 38.9%. The median of moderatetovigorous physical activity (MVPA) time was 0.20 h/d, and physical activity sufficiency rate was 7.8%. The median of screen time was 1.79 h/d, and the screen time compliance rate was 68.2%. The binary Logistic regression results showed that lower levels of MVPA time and increased screen time were associated with a higher risk of overweight and obesity among children and adolescents with special needs [OR(95%CI)=1.80(1.06-3.07), 2.40(1.42-4.07),P<0.05]. Conclusions Insufficient physical activity and excessive screen time are associated with an increased risk of overweight and obesity among children and adolescents with special needs. Therefore, comprehensive intervention measures should be implemented as early as possible to prevent and reduce the incidence of overweight and obesity in this population.

Objective: To investigate the prevalence and influencing factors of menopausal syndrome among postmenopausal women in Pan'an County, Zhejiang Province, so as to provide the basis for guiding the health management of postmenopausal women. Methods: From May 2023 to April 2024, the postmenopausal women aged 40 to 69 years in Pan'an County were selected using the random cluster sampling method. Demographic information, lifestyle and prevalence of gynecological diseases were collected through questionnaire surveys. The prevalence of menopausal syndrome was assessed by modified Kupperman Score Scale. Factors affecting menopausal syndrome were analyzed by a multivariable logistic regression model. Results: A total of 816 postmenopausal women were surveyed, with an mean age of (57.63±2.92) years and a mean natural menopause age of (49.85±2.13) years. There were 574 cases with menopausal syndrome, with a prevalence of 70.34%. Flashes and sweating, insomnia and irritability were common symptoms, accounting for 62.87%, 47.43% and 41.18%, respectively. Multivariable logistic regression analysis showed that monthly personal income of ≤5 000 yuan (<3 000 yuan, OR=3.124, 95%CI: 1.829-5.335; 3 000-5 000 yuan, OR=2.399, 95%CI: 1.370-4.201) and having gynecological diseases (OR=1.970, 95%CI: 1.292-3.004) were associated with a higher risk of menopausal syndrome, while average (OR=0.141, 95%CI: 0.072-0.276) or sufficient sleep quality (OR=0.095, 95%CI: 0.049-0.185) were associated with a lower risk of menopausal syndrome. Conclusion The prevalence of menopausal syndrome among postmenopausal women in Pan'an County is relatively high, and is mainly influenced by personal economic status, sleep quality and the presence of gynecological diseases.

BACKGROUND: Drug resistance is the main cause of high mortality of lung cancer. This study was conducted to investigate the effect of folic acid (FA) on the resistance of non-small cell lung cancer (NSCLC) cells to Osimertinib (OSM) by regulating the methylation of dual specificity phosphatase 1 (DUSP1). METHODS: The OSM resistant NSCLC cell line PC9R was establishd by gradually escalation of OSM concentration in PC9 cells. PC9R cells were randomly grouped into Control group, OSM group (5 μmol/L OSM), FA group (600 nmol/L FA), methylation inhibitor decitabine (DAC) group (10 μmol/L DAC), FA+OSM group (600 nmol/L FA+5 μmol/L OSM), and FA+OSM+DAC group (600 nmol/L FA+5 μmol/L OSM+10 μmol/L DAC). CCK-8 method was applied to detect cell proliferation ability. Scratch test was applied to test the ability of cell migration. Transwell assay was applied to detect cell invasion ability. Flow cytometry was applied to measure and analyze the apoptosis rate of cells in each group. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) method was applied to detect the expression level of DUSP1 mRNA in cells. Methylation specific PCR (MSP) was applied to detect the methylation status of the DUSP1 promoter region in each group. Western blot was applied to analyze the expression levels of DUSP1 protein and key proteins in the DUSP1 downstream mitogen-activated protein kinase (MAPK) signaling pathway in each group. RESULTS: Compared with the Control group, the cell OD450 values (48 h, 72 h), scratch healing rate, number of cell invasions, and expression of DUSP1 in the OSM group were obviously decreased (P<0.05); the apoptosis rate, the methylation level of DUSP1, the expression of p38 MAPK protein, and the phosphorylation level of extracellular regulated protein kinases (ERK) were obviously increased (P<0.05); the cell OD450 values (48, 72 h), scratch healing rate, number of cell invasions, and expression of DUSP1 in the DAC group were obviously increased (P<0.05); the apoptosis rate, the expression of p38 MAPK protein, the phosphorylation level of ERK, and the methylation level of DUSP1 were obviously reduced (P<0.05). Compared with the OSM group, the cell OD450 values (48, 72 h), scratch healing rate, number of cell invasions, and expression of DUSP1 in the FA+OSM group were obviously decreased (P<0.05); the apoptosis rate, the methylation level of DUSP1, the expression of p38 MAPK protein, and the phosphorylation level of ERK were obviously increased (P<0.05). Compared with the FA+OSM group, the cell OD450 values (48, 72 h), scratch healing rate, number of cell invasions, and expression of DUSP1 in the FA+OSM+DAC group were obviously increased; the apoptosis rate, the methylation level of DUSP1, the expression of p38 MAPK protein, and the phosphorylation level of ERK were obviously reduced (P<0.05). CONCLUSIONS FA may inhibit DUSP1 expression by enhancing DUSP1 methylation, regulate downstream MAPK signal pathway, then promote apoptosis, inhibit cell invasion and metastasis, and ultimately reduce OSM resistance in NSCLC cells.

Objective To investigate the changes of OAT expression in bone cells in chronic renal failure(CRF)and involved mechanism,and to explore the effect of OAT expression on bone metabolism.Methods Ra-ndomly divide the rats into a control group(n=6)and a model group(n=6).The model group established a rat chronic renal failure model using"single nephrectomy+adenine gavage"method,and the red blood cell(RBC)and hemoglobin(HGB)of the rat body were measured using a blood routine analyzer;Measure indicators such as creatinine(Cr),urea nitrogen(BUN),uric acid(UA),blood calcium(Ca2+),and blood phosphorus(P3+)using a fully automated biochemical analyzer;Pathological examination of rat kidneys;X-ray examination of rat tibia;Immunohistochemical examination of bone tissue OAT1 level.Results The bone density of the model group rats is lower than that of the control group;The calcium and phosphorus metabolism of rats in the model group was in metabolic disorder,and the OAT1 value of bone tissue binding was much lower than that of the control group(P= 0.0018),which was statistically significant.(P=0.0018)Conclusion Chronic renal failure affected the binding ability of OAT1 in bone tissue,leading to the metabolic disorder for calcium absorption and phosphorus metabolism,thus aggravating renal osteodystrophy(P<0.05).

Objective To evaluate five types of DIC scoring systems based on sepsis patients,to explore the values of different DIC scoring systems in the occurrence and prognosis of DIC in sepsis patients,and to compare the applicability of different DIC scoring systems for sepsis complicated with DIC.Methods Laboratory indexes and clinical data from sepsis patients who had been hospitalized in Gansu Provincial People's Hospital from December 1,2019 to December 31,2021 were retrospectively analyzed within 24 hours.Five types of DIC scoring systems were used to score,and the difference of diagnostic rate and discharge outcome in sepsis patients with different severity was compared.The ROC curves of five DIC scoring systems were established to evaluate the accu-racy of DIC in sepsis patients.Results The fatality rate of sepsis increased with the severity of sepsis(P<0.05).There were statistically significant differences in discharge outcomes between DIC and non-DIC in the five scoring systems(P<0.05).JMHW,CDSS and part of ISTH were detected in JAAM cases,while ISTH was detected in non-dominant ISTH cases.ISTH,JAAM,JMHW,CDSS,and non-dominant ISTH5 scoring systems were used to diagnose DIC,and absence of full health restoration and death were 3.0,3.8,4.2,3.9,and 3.0 times higher than non-DIC cases,respectively.Conclusion JAAM scoring system has higher diagnostic rate and sensitivity for adult sepsis.CDSS and JMHW scoring systems are more accurate in predicting the prognosis of sepsis patients.

Objective To explore the application of Plan-Do-Check-Act(PDCA)cycle management to continuously im-prove the service quality of outpatient pharmacy and enhance patient satisfaction.Methods To address the problem of long wait-ing time for patients in outpatient pharmacy,we applied PDCA cycle to investigate the factors affecting patients'waiting time in the process of medicine collection,analyze the current situation,determine the expected goals,formulate the service quality im-provement plan of outpatient pharmacy,implement the improvement plan,follow up and supervise,and summarize and analyse the problems regularly until it was solved.Results After implementing the PDCA cycle in the management,the service quality of outpatient pharmacy was improved,the waiting time was significantly shortened and the satisfaction of medical treatment was in-creased.Conclusion The application of PDCA cycle method is effective in improving the service quality of outpatient pharmacy.Therefore,it is recommended for broader implementation.

OBJECTIVE To analyze the use status and development trend of proton pump inhibitors(PPIs) in 33 hospitals in Wuhan, Hubei Province after the implementation of the national centralized drug procurement(NCDP) policy, and to provide reference for promoting the subsequent rational use of NCDP drugs and improving related policies. METHODS To make statistics and analysis of purchasing amount of PPIs, defined daily dose system(DDDs), defined daily dose consumption(DDDc) and utilization rate of 33 hospitals in Wuhan in 2019 and 2022. RESULTS After the implementation of the NCDP policy, the total purchasing amount of PPIs decreased by 53.6%, DDDs decreased by 15.4%, DDDc decreased by 45.2%, and the utilization rate of PPIs injectable dosage forms decreased by 12.6%. After NCDP, the highest growth rate of oral dosage forms was omeprazole(5.7%), followed by rabeprazole(5.0%), while injectable dosage forms showed a significant difference in utilization rate, with a significant decline in NCDP varieties and a significant increase in non-NCDP varieties. The overall NCDP utilization rate of PPIs in Wuhan was 64.9%, with little difference among hospitals of different grades. CONCLUSION The NCDP policy achieves the purpose of reducing the drug cost of patients and improving the accessibility of drugs, and is more optimized in the selection of dosage forms, which is in line with the policy expectations overall; but the quantity and price of PPIs in Wuhan decreased after NCDP, and highlighted a certain tendency in the selection of varieties. In the future, we still need to optimize measures to guide clinical priority in the selection of NCDP drugs, to ensure and improve the implementation of NCDP policy.

OBJECTIVE To mine and analyze the post-marketing adverse drug event （ADE） signals of irinotecan in adults and children populations， and to provide a reference for clinical safe medication. METHODS ADE reports of irinotecan from the first quarter of 2004 to the first quarter of 2023 in the US FDA adverse event reporting system database were extracted and the risk signals of irinotecan were detected through the reporting odds ratio and proportional reporting ratio. Statistical analysis was performed for ADE reports and signals of patients aged＜18 years （children） and ≥18 years （adults）. RESULTS A total of 8 013 ADE reports with irinotecan as the primary suspect drug were identified， including 7 656 and 357 ADE reports in adults and children， respectively. A total of 518 and 75 ADE signals were detected in the adults and children， and the mainly involved systems and organs including gastrointestinal disorders， blood and lymphatic system disorders， systemic disorders and various reactions at the administration site， etc. Most of the top 20 ADE signals in terms of frequency were documented in the drug instructions of irinotecan. New ADE signals in adults included peripheral neuropathy， oral mucosal inflammation， pulmonary embolism， epidermal nevus syndrome and reproductive toxicity， while hypertension， progressive neoplasms， tumor lysis syndromes， and embolism were new ADE signals in children. CONCLUSIONS The above new suspected high-risk signals not mentioned in the instructions should raise a high level of alertness in clinical practice of irinotecan.
