Objective:
To establish a risk assessment system for infectious disease prevention and control in schools in Shangcheng District, Hangzhou and determine risk levels for each school, and propose corresponding risk management measures, so as to provide a scientific reference for infectious disease prevention and control in primary and secondary schools.
Methods:
Based on the Failure Mode and Effects Analysis (FMEA) method, potential failure analysis and current situation investigation of infectious disease prevention and control risks were conducted in 110 primary and secondary schools from 2022 to 2024 in Shangcheng District, Hangzhou. Risk levels were classified using K-Means cluster analysis.
Results:
Through expert panel discussions using FMEA, 6 first level indicators and 28 second level indicators were identified. The top three risk priority numbers were implementation of required prevention and control measures for clustered infectious disease outbreaks in schools in the past three years ( 189.00 ), student morning/afternoon health checks (168.00), and reporting status of clustered infectious disease outbreaks in schools in the past three years (144.00). The comprehensive prevention scores of schools ranged from 61.00 to 98.00 (mean: 87.40 ). There were no statistically significant differences in the average scores(primary school: 88.17±7.39, nine year consistent education: 86.26±7.68, junior high school: 85.55±8.20, and high school: 88.72±4.91) and risk level distribution of schools with different educational stages( F/H=0.95,1.47, P >0.05).K-Means cluster analysis divided the schools into 5 risk levels with cluster centers at 93.25, 85.78, 79.69, 70.29, 61.00 ( F=309.21, P <0.05), with 80% of schools classified as low risk or below.
Conclusion
The infectious disease prevention and control risk assessment system for primary and secondary schools can be established, and hierarchical management can be conducted according to school risk levels, thereby improving the efficiency and effectiveness of school infectious disease prevention and control, and enhancing the precision and sustainability of prevention efforts.
2.Correlation between depressive symptom and traditional Chinese medicine constitution among school aged children and adolescents
Chinese Journal of School Health 2025;46(9):1222-1225
Objective:
To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom.
Methods:
From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted.
Results:
The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05).
Conclusions
Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

AIM:This study aimed to investigate the expression and localization of ALOX12P2 in oral squa-mous cell carcinoma(OSCC),as well as its effects on cell viability,migration,and invasion.METHODS:The expres-sion of ALOX12P2 in head and neck squamous cell carcinoma(HNSCC)tissues and its correlation with clinicopathologi-cal features were analyzed using the UALCAN database(University of Alabama at Birmingham Cancer Data Analysis Por-tal).Additionally,the expression of ALOX12P2 in OSCC and its impact on survival prognosis were evaluated through the GDC and UCSC Xena databases.The expression levels of ALOX12P2 in OSCC cell lines were assessed via quantitative re-al-time PCR(RT-qPCR).The subcellular localization of ALOX12P2 was determined using nucleoplasmic RNA isola-tion.CAL-27 cells were used to establish an ALOX12P2 knockdown group(SS-ALOX12P2)and a control group(SS-NC).HN30 cells were employed to form an ALOX12P2 overexpression group(ALOX12P2)and a control group(vector).The effects of altered ALOX12P2 expression on the epithelial-mesenchymal transition(EMT)-related gene E-cadherin and the PI3K/AKT signaling pathway were assessed through Western blot analysis.RESULTS:ALOX12P2 expression was significantly higher in HNSCC and OSCC tissues compared to normal tissues,with its expression correlating with poor prog-nosis.RT-qPCR analysis indicated that the relative expression of ALOX12P2 in OSCC cells was comparable to that in nor-mal cells(P<0.05).RNA nucleoplasmic isolation confirmed that ALOX12P2 localized in the nucleus.In comparison to the SS-NC group,the SS-ALOX12P2 group exhibited a marked reduction in ALOX12P2 expression(P<0.01),alongside significant decreases in cell viability,migration,and invasion(P<0.01).Conversely,the ALOX12P2 group showed sub-stantially higher relative expression compared to the vector group(P<0.01),with enhanced cell viability,migration,and invasion abilities(P<0.01).Western blot analysis demonstrated that ALOX12P2 knockdown resulted in upregulation of E-cadherin and downregulation of N-cadherin and Vimentin(P<0.01),while overexpression of ALOX12P2 yielded the opposite effects(P<0.01).Knockdown of ALOX12P2 led to decreased protein expression of p-PI3K and p-AKT(P<0.01),whereas overexpression increased these protein levels(P<0.01).CONCLUSION:ALOX12P2 is highly ex-pressed in OSCC and promotes cell viability,migration,and invasion.This effect may be linked to the activation of the PI3K/AKT signaling pathway,which facilitates the epithelial-mesenchymal transition(EMT)process.

ObjectiveTo investigate the effect of Yunkang oral liquid on postpartum kidney deficiency in mice. MethodPostpartum mice were randomized into model and low-dose (6 mL·kg-1), medium-dose (9 mL·kg-1), and high-dose (12 mL·kg-1) Yunkang oral liquid groups. The mouse model of postpartum kidney deficiency was established by sleep deprivation combined with forced swimming. Another 9 female ICR mice were selected as the normal control group. The mice were administrated with Yunkang oral liquid during the period of modeling. The levels of estradiol (E2), progesterone (P), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) in the serum were measured by the enzyme-linked immunosorbent assay. The morphological changes of ovaries and uterus were observed by hematoxylin-eosin (HE) staining, and the expression of transforming growth factor (TGF)-β and Smad2/3 was determined by immunohistochemistry and Western blotting. ResultThe mice in the model group showed prolonged estrous cycle, reduced voluntary activity, dorsal temperature, grip strength, and bone strength, and whitening tongue coating. Compared with the model group, Yunkang oral liquid shortened the estrous cycle, increased the voluntary activity, dorsal temperature, grip strength, and bone strength, and alleviated the whitening of tongue coating. Moreover, it elevated the E2 and P levels and lowered the FSH and LH levels in the serum, decreased ovarian follicular atresia rate, promoted uterine repair, and down-regulated the expression of TGF-β and Smad2/3 in the ovarian and uterine tissues. ConclusionYunkang oral liquid can ameliorate postpartum kidney deficiency in mice by regulating the TGF-β/Smads signaling pathway.

ObjectiveTo explore the drug resistance of Morganella morganii (Mm) and the risk factors for extended-spectrum β-lactamase (ESBL) positive infection in type 2 diabetes foot (DF) patients with Mm, and to provide a reference for clinical treatment. Methods310 samples of DF patients with Mm infection were collected from Shanghai Integrated Traditional Chinese and Western Medicine Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from January 2020 to March 2023. The patients were selected for the first time to detect Mm bacteria through cultivation, and were divided into ESBL producing group (n=45) and non ESBL producing group (n=265). Bacterial identification and drug sensitivity experiments on Mm were conducted. Multivariate logistic regression analysis was used to analyze the risk factors. The stepwise regression method (SRM) was used to screen the most important correlation factors for constructing risk prediction model and its evaluation. ResultsBoth ESBL producing and non ESBL producing Mm were sensitive to imipenem (IPM) and meropenem (MEM). Compared with the non ESBL producing group, the resistance of Mm in the ESBL producing group to other tested antibiotics [excluding ampicillin (AM)/sulbactam (SU)] was higher (P<0.05). Aged ≥60 years old, concomitant hypoproteinemia (HP), combined use of antibiotics, and history of third-generation cephalosporin use were all independent risk factors for the occurrence of ESBL producing strain infection (P<0.05). SRM screening identified age, HP, and use of third-generation cephalosporins as the most associated factors with ESBL producing strain infection, and these three factors were included in the multivariate logistic regression prediction model. After calculation, when P=0.80, the Jordan index was the highest and the prediction effect was the best. The prediction accuracy was 89.35%, the sensitivity was 86.67%, and the specificity was 89.81%. The model evaluation results showed that the predictive model has good discrimination and high accuracy. ConclusionThe Mm strain producing ESBL has strong resistance to commonly used antibiotics, and it is recommended that clinical physicians use antibiotics reasonably. Age, HP, combined use of antibiotics, and use of third-generation cephalosporins are all independent risk factors for the occurrence of ESBL producing bacterial infections. Clinical monitoring should be carried out on susceptible populations based on risk factors, and infection management should be strengthened.

Objective:
To elucidate the differences in manual acupuncture effectiveness at sensitized points by investigating the mechanisms of local skin action at different sensitization points in rats with knee osteoarthritis (KOA).
Methods:
Forty Sprague–Dawley rats were equally divided into control, model (1 mg of monoiodoacetate into the right knee joint cavity), sham operation, manual acupuncture at right Tianjing acupoint (MAR-SJ 10), and left SJ 10 groups. Safranine-O and fast green staining were used to assess the modeling. The morphological and functional changes in mast cells (MCs) were assessed during acupoint sensitization using toluidine blue and immunofluorescence staining. The levels of serotonin, histamine, substance P (SP), and tryptase at skin acupoints and serum levels of IL-β, IL-6, and TNF-α were detected using ELISA.
Results:
After 14 days of treatment, the number of MCs and their degranulation rates were statistically higher in the model group than in the control group (both P < .001). After applying acupuncture, the levels of 5-HT, HA, and SP at skin acupoints were lower than those in the model group (all P < .05), and tryptase level was higher (both P < .05). Tryptase level was higher on the skin at the MAL-SJ 10 acupoint than that on the MAR-SJ 10 acupoint (P = .004). Compared with the model group, the serum levels of IL-1β, IL-6, and TNF-α in the MAR-SJ 10 and MAL-SJ 10 groups were lower (all P < .05).
Conclusion
Acupuncture at KOA-sensitized acupoints mitigates joint injury in KOA rats and may bidirectionally regulate local MCs of these acupoints. This finding not only enhances the reference value of sensitizing points in clinical diagnosis and treatment, but also contributes to the understanding of the biological mechanisms underlying acupuncture intervention at sensitizing points.

Objective:To understand the current status of gastroscopy in diagnosing gastric lesions in general population, and to recommend the optimal age for the first gastroscopy and intervals for repeated gastroscopy.Methods:The gastroscopy records of residents aged 18-80 years in Yinzhou District of Ningbo, Zhejiang Province, between April 2010 and December 2021 were analyzed retrospectively. The detections of gastric lesions across different years, age and genders were described. Goodness of fit tests were applied to compare the differences in detection rates of different lesions in first-time endoscopy in different age groups and different populations. Generalized additive models were used to fit the trend of age specific gastric lesion detection rate explore the optimal age for gastroscopy. The appropriate gastroscopy intervals were determined according to the progress of the gastric lesions detected in repeated gastroscopy.Results:A total of 237 751 participants with 344 398 gastroscopy records were included in analyses. A total of 5 597 cases of chronic atrophic gastritis (CAG), 9 796 cases of intestinal metaplasia (IM), 165 cases of low-grade intraepithelial neoplasia (LGIN), 52 cases of high-grade intraepithelial neoplasia (HGIN) and 435 cases of gastric cancer were detected by the first gastroscopy. The overall detection rate of gastric lesions increased significantly in age group 45-70 years, and remained stable after 70 years old, with LGIN and HGIN showing notable increases at 50 and 55 years old, respectively. Repeated gastroscopy detected CAG, IM, LGIN, and HGIN at a higher rate compared with the first gastroscopy. Normal/superficial gastritis progressed in 3-5 years, whereas CAG or more severe lesions progressed in 1-6 years.Conclusion:Gastroscopy is recommended for general population aged 45 years and above. Furthermore, gastroscopy can be performed every 3-5 years for individuals with normal endoscopy results and once a year for patients with CAG or more severe gastric lesions.
