Background Public places are important areas for daily human activities. Frequent contact with public items promotes their role as vehicles for microbial spread, creating a substantial risk for the transmission of pathogenic microorganisms. Objective To understand the hygiene status and influencing factors of public items in typical public places in Shanghai from 2010 to 2024, and to provide a scientific basis for optimizing the hygiene management of public items. Methods Based on the monitoring data of public items in public places in Shanghai from 2010 to 2024, the hygiene status was evaluated in three stages: 2010–2019, 2020–2022, and 2023–2024. Chi-square test and logistic regression were used to analyze the impact of factors such as monitoring stages, public place types, and public item categories on the hygiene status. Results The public items in 13807 public places were monitored. A total of 1 022 bed sheets and 9 271 towels were tested for pH value, with qualified rates of 77.66% and 87.81%, respectively. The OR (95%CI) for the pH compliance of towels relative to bed sheets was 1.77 (1.45, 2.15). Compared with bathing places, the ORs for pH compliance of towels in hair salons and beauty salons were 2.24 (1.75, 2.87) and 2.15 (1.57, 2.95), respectively. Additionally, a total of 221 650 samples from various public items were tested for microorganisms, yielding 215554 qualified samples, with an average qualified rate of 97.25%. The qualified rates for total bacterial count, total fungal count, coliforms, and Staphylococcus aureus were 92.66%, 94.63%, 98.85%, and 99.84%, respectively. The logistic regression analysis showed that, compared to the 2016–2019 baseline, no statistically significant differences were observed in the qualified rates of total fungal count across different stages; however, significantly higher qualified rates for total bacterial count, total fungal count, coliforms, and Staphylococcus aureus were recorded during 2020–2022, with ORs (95%CI) of 1.27 (1.16, 1.38), 23.20 (8.42, 63.94), and 12.08 (1.63, 89.92), respectively. Conclusion The pH compliance ranks among the top tier nationwide for cotton textile goods in Shanghai, suggesting minimal detergent retention. Furthermore, continuous improvement in cleaning and disinfection measurements has markedly enhanced the microbial hygiene of public items in public places.

ObjectiveTo investigate the role and mechanism of thymic stromal lymphopoietin （TSLP） in a mouse model of acetaminophen （APAP）-induced acute liver injury. MethodsA total of 16 wild-type （WT） male C57BL/6J mice were randomly divided into control group and APAP group， with 8 mice in each group， and the mice in the APAP group were given intraperitoneal injection of APAP solution at a dose of 400 mg/kg to establish an animal model， while those in the control group were given injection of an equal volume of normal saline， with samples collected after 6 hours. An automatic chemical analyzer was used to measure the serum levels of alanine aminotransferase （ALT） and aspartate aminotransferase （AST）； quantitative real-time PCR was used to measure the mRNA expression levels of the inflammatory factors tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） in liver tissue； the kit was used to measure the content of glutathione （GSH） in liver tissue homogenate； quantitative real-time PCR and Western blot were used to measure the transcriptional level and protein expression level of TSLP. Furthermore， 22 WT male C57BL/6J mice were randomly divided into control group with 8 mice， APAP group with 8 mice， and APAP+recombination TSLP （rTSLP） group with 6 mice； the mice in the APAP+rTSLP group were given intraperitoneal injection of rTSLP solution， while those in the control group and the APAP group were given injection of the solvent PBS； after 30 minutes， the mice in the APAP+rTSLP group and the APAP group were given injection of APAP solution， while those in the control group were given injection of an equal volume of normal saline. The serum levels of ALT and AST were measured； HE staining was used to observe the pathological changes of the liver； kits were used to measure the levels of the oxidative stress indices malondialdehyde （MDA） and superoxide dismutase （SOD） in liver tissue homogenate； Western blot was used to measure the expression levels of the autophagy-related proteins LC3‍Ⅰ/Ⅱ， Beclin1， and P62 and the molecules such as nuclear factor erythroid 2-related factor 2 （Nrf2）， protein kinase B （Akt）， phosphorylated Akt （p-Akt）， mammalian target of rapamycin （mTOR）， and phosphorylated mTOR （p-mTOR）. In addition， 16 WT male C57BL/6J mice and 16 TSLP receptor-silenced （TSLPR^-/-） mice were divided into WT mouse control group， WT mouse APAP group， TSLPR^-/- mouse control group， and TSLPR^-/- mouse APAP group， with 8 mice in each group； the mice in the WT mouse APAP group and the TSLPR^-/- mouse APAP group were used for modeling by intraperitoneal injection of APAP solution at a dose of 400 mg/kg， and those in the WT mouse control group and the TSLPR^-/- mouse control group were given injection of an equal volume of normal saline. The serum levels of ALT and AST and the content of MDA in liver tissue were measured for these four groups， and Western blot was used to measure the protein expression levels of LC3Ⅰ/Ⅱ， Akt， and p-Akt. The independent-samples t test was used for comparison of continuous data between two groups； a one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsAfter the mouse model of APAP-induced acute liver injury was established successfully， there were significant increases in the mRNA and protein expression levels of TSLP compared with the control group （both P<0.01）. In the study of rTSLP， compared with the control group， the APAP group had significant increases in ALT and AST （both P<0.001） and radial necrosis along the central vein observed by HE staining of liver tissue， as well as significant reductions in the protein expression levels of the oxidative stress indices SOD and Nrf2 and a significant increase in the level of MDA （all P<0.01）； compared with the APAP group， the APAP+rTSLP group had significant reductions in ALT and AST， a significant reduction in necrotic area of liver tissue， significant increases in the protein expression levels of SOD and Nrf2， and a significant reduction in MDA （all P<0.05）； there were significant differences in the protein expression levels of LC3Ⅰ/Ⅱ， Beclin1， P62， p-Akt， and p-mTOR between the APAP+rTSLP group and the control group （all P<0.01）. In the study of TSLPR^-/- mice， compared with the WT mice after modeling， the TSLPR^-/- mice had significant increases in the levels of ALT， AST， and MDA and significant reductions in the expression levels of LC3Ⅰ/Ⅱ and p-Akt （all P<0.05）. ConclusionTSLP can increase autophagy， reduce oxidative stress， and thus improve acute liver injury induced by APAP overdose， possibly by activating the PI3K/Akt signaling pathway and inhibiting mTOR.

ObjectiveTo observe the effect of gene mutation on the effectiveness of arsenic-containing Chinese herbal compound formulas in the treatment of myelodysplastic syndromes （MDS） of different traditional Chinese medicine （TCM） patterns， so as to provide the basis for the clinical application. MethodsClinical data of 442 MDS patients who were treated with arsenic-containing herbal compound formulas were retrospectively collected， including the baseline demographic and clinical characteristics of the patients. Based on the TCM four examinations， the patients were divided into the spleen-kidney deficiency group as well as the qi-yin deficiency group， and according to the results of the next-generation sequencing （NGS） test， they were divided into the group with and without gene mutation respectively. The influence of gene mutation on the clinical effectiveness of patients with different TCM patterns was analyzed， the baseline demographic and clinical characteristics of the patients with different outcomes of the two TCM patterns were compared， and multivariate Logistic regression analysis was conducted on the influencing factors of the effective rate of MDS patients with gene mutation. ResultsA total of 190 cases were included in the spleen-kidney deficiency group （119 cases with gene mutation） and 43 cases in the qi-yin deficiency group （23 cases with gene mutation）. No statistically significant differences were noted in effectiveness assessment， total effective rate， and total response rate between the spleen-kidney deficiency group and the qi-yin deficiency group （P＞0.05）. In the spleen-kidney deficiency group， the total effective rate of MDS with gene mutation was 65.55% （78/119）， which was lower than 80.28% （57/71） of MDS without gene mutation， with statistical significance （P = 0.033）， while no statistical differences in effectiveness assessment and total response rate were noted （P＞0.05）. In the qi-yin deficiency group， no statistical differences were observed in effectiveness assessment， total effective rate， and total response rate of the patients in with or without gene mutation （P＞0.05）. In the spleen-kidney deficiency group with gene mutation， the rate of complex karyotype （P = 0.031） and the mutation rate of CBL gene （P = 0.032） in the ineffective population were higher than those in the effective population， while the mutation rate of DDX41 gene in the effective population was higher than that in the ineffective population （P = 0.033）. No statistically significant differences were found in other gene mutations， age， gender distribution， number of gene mutations， bone marrow hyperplasia degree， blast cell range， reticular fiber tissue proliferation or not， and prognosis of chromosomal abnormalities between the effective and ineffective populations （P＞0.05）. In the qi-yin deficiency group with gene mutation， no statistically significant differences were found in various items between populations with different outcomes （P＞0.05）. Multivariate Logistic regression analysis showed that complex karyotype， CBL mutation， and DDX41 mutation were independently associated with the effective rate of MDS with spleen-kidney deficiency and gene mutation （P＜0.05）. DDX41 mutation was an independent protective factor in the spleen-kidney deficiency group （OR＞1）， while complex karyotype and CBL mutation were independent risk factors （OR＜1）. ConclusionThe arsenic-containing TCM compound formulas exhibited better effectiveness in MDS with spleen-kidney deficiency pattern without mutation； and in MDS with spleen-kidney deficiency pattern without complex karyotypes， CBL mutation， and with DDX41 mutations. Furthermore， DDX41 mutation was an independent protective factor in the spleen-kidney deficiency group， while complex karyotype and CBL mutation were independent risk factors. In MDS with qi-yin deficiency pattern， gene mutation-related factors showed no significant impact on the effectiveness of arsenic-containing TCM compound formulas.

This paper summarizes Professor SHI Zaixiang's clinical experience in treating high fever caused by sepsis using Chaihu Guizhi Ganjiang Decoction （柴胡桂枝干姜汤）. He holds that the key pathogenesis of sepsis involves constrained heat in the shaoyang and internal accumulation of water and fluids. The clinical manifestations such as high fever， chills， and alternating sensations of cold and heat are attributed to pathogenic heat constrained in the shaoyang. Meanwhile， soft tissue edema and serous cavity effusions are due to shaoyang dysfunction and internal water retention. In clinical practice， treating sepsis-related high fever requires addressing both the shaoyang-constrained heat and the associated edema and effusions. The therapeutic approach focuses on harmonizing the shaoyang and resolving internal fluids， using Chaihu Guizhi Ganjiang Decoction as the base formula with flexible modifications. Professor SHI emphasizes that this formula shows a rapid antipyretic effect， particularly in cases where multiple anti-infective treatments have failed.

Background Swimming is becoming increasingly popular for its combined leisure and fitness benefits. However, polluted swimming pool water may pose various health risks. Previous studies have indicated that health indicators of swimming venues have lower qualification rates compared to other public places, highlighting the urgent need to optimize hygiene management measures. Objective To assess the overall hygiene status and identify the key factors influencing water quality in Shanghai’s swimming venues from 2010 to 2024, and to provide a scientific basis for optimizing water quality management. Methods Water quality was assessed in three stages (2010—2019, 2020—2022, and 2023—2024) based on the monitoring data of Shanghai’s swimming venues (2010—2024). The influences of monitoring stage, region, season, scale, day of week, and per capita attendance on water quality were analyzed using chi-square tests and logistic regression. Results From 2010 to 2024, water quality was monitored in 1478 swimming venues. The compliance rates of turbidity, pH, urea, oxidation-reduction potential, free residual chlorine, combined residual chlorine, total bacteria, coliforms, and heat-resistant coliforms in swimming pool water, and free residual chlorine in the foot disinfection basin water samples were 99.56%, 94.73%, 73.00%, 47.50%, 56.55%, 54.12%, 97.74%, 99.49%, 99.90%, and 69.19%, respectively. The overall water quality compliance rate was 85.28%. The main non-compliant indicators for swimming pool water were urea, ORP, free residual chlorine, and combined residual chlorine, along with free chlorine residual in the foot disinfection basin water samples. Using the period before the implementation of the new national standard as reference, the results of logistic regression revealed that the qualification rates of urea, ORP, and free residual chlorine in the swimming pool water samples, as well as free residual chlorine in foot disinfection basin water samples, were significantly higher during the two phases after launching the new standard (2020–2022 and 2023–2024), and the associated odds ratios (95%CI) were 1.28 (1.00, 1.64) and 1.48 (1.12, 1.95), 13.35 (7.63, 23.37) and 10.78 (7.00, 16.60), 2.54 (1.81, 3.58) and 3.18 (2.41, 4.20), and 3.14 (2.14, 4.60) and 2.83 (1.89, 4.23), respectively. Compared with the reference group, those sampled in urban pools and in non-summer seasons showed higher qualification rates of urea and ORP; in contrast, the pools with high visitor flow showed lower qualification rates of free residual chlorine in both water samples of swimming pools and foot disinfection basins (P<0.05). Conclusion The implementation of the new national standard has effectively enhanced the management standards and significantly improved overall water quality of swimming venues in Shanghai. However, the compliance rates of free residual chlorine and urea in swimming pool water still need further improvement. The compliance of some indicators is influenced by region, season, scale, and average passenger flow, particularly in small suburban swimming venues. Future efforts should focus on refining water quality management strategies and enhancing public health management.

Objective:To investigate the application effect of a novel zipper device in wound healing after incision and drainage of cuta-neous abscesses in children,and to explore its optimal intervention timing.Methods:A total of 50 children who attended the outpatient service of Department of Pediatric surgery from September 2023 to September 2024 were enrolled and divided into two groups accord-ing to the parity of the date of visit.The 26 children with the odd date of visit were enrolled as experimental group,and the 24 children with the even date of visit were enrolled as control group.The same anti-infective dressings were used for wound dressing in both groups after incision and drainage,and when there was a significant reduction in wound exudate and the fresh granulation tissue emerged at wound base,the zipper device was used for the children in the experimental group,and dressing change was performed for the children in the control group until the wound was completely healed.The two groups were compared in terms of wound healing time,healing rate,and the total costs of dressing change,and the multiple linear regression model and the restricted cubic spline(RCS)model were used to analyze the association between the in-tervention time of the zipper device and wound healing time.Re-sults:Compared with the control group,the experimental group had a significantly shorter wound healing time,a significantly higher wound healing rate,and significantly lower total costs of dressing change(P<0.001).The multiple linear regression model showed that the infection size of skin abscess and the intervention time of the zipper device were strongly associated with wound healing time(P<0.05).After adjustment for infection size,the RCS model analysis showed a significant linear dose-response relationship between intervention time and wound healing time(Pnonlinear=0.406),and wound healing time shortened with the reduction in intervention time(P<0.001).Conclusion:The application of the novel zipper device can help with the healing of cutaneous abscesses in children,and it is recommended to apply the device as early as possible after control of wound infection,in order to promote early wound healing.

Objective To analyze the clinical,pathological and CT features of mediastinal carcinoid so as to improve the diagnostic accuracy.Methods The clinical,pathological and imaging data of 4 patients with mediastinal carcinoid were analyzed retrospectively.Results All 4 patients were elderly male,in which 3 cases had elevated serum neuron specific enolase(NSE)before operation and other one was not examined.All tumors were atypical carcinoid with Ki-67 expression of 5％-25％and positive expression of Syn,CD56,CK and CgA.The CT showed the lateral mass on the left(n=3)or both(n=1)sides of the anterior mediastinum,3 of which grew along the vascular space and could not be clearly demarcated from the pericardium and cardiovascular system.The lesions were large with irregular shape in 3 cases and round shape in 1 case,with heterogeneous density in 3 cases and homogeneous density in 1 case,with intratumoral calcification in 2 cases.Contrast enhanced CT showed the lesions with mild or moderate progressive enhancement,3 of which had supplying vessels from internal thoracic artery.The enlarged mediastinal lymph nodes were found in 3 cases and bone metastasis was in 1 case.Conclusion Mediastinal carcinoid is more common in elderly male,usually with elevated serum NSE.CT shows lateral mass in the anterior mediastinum with heterogeneous density,intratumoral calcification,mild or moderate progressive enhancement,and supplying vessels from internal thoracic artery.The larger lesion is indistinguishable from the adjacent lung tissue and cardiovascular system,usually with intrathoracic and extrathoracic lymph node metastasis.

BACKGROUND: Tri-ponderal mass index (TMI) has been reported to be a more accurate estimate of body fat than body mass index (BMI). This study aims to compare the effectiveness of TMI and BMI in identifying hypertension, dyslipidemia, impaired fasting glucose (IFG), abdominal obesity, and clustered cardio-metabolic risk factors (CMRFs) in 3- to 17-year-old children. METHODS: A total of 1587 children aged 3 to 17 years were included. Logistic regression was used to evaluate correlations between BMI and TMI. Area under the curves (AUCs) were used to compare discriminative capability among indicators. BMI was converted to BMI- z scores, and accuracy was compared by false-positive rate, false-negative rate, and total misclassification rate. RESULTS: Among children aged 3 to 17 years, the mean TMI was 13.57 ± 2.50 kg/m 3 for boys and 13.3 ± 2.33 kg/m 3 for girls. Odds ratios (ORs) of TMI for hypertension, dyslipidemia, abdominal obesity, and clustered CMRFs ranged from 1.13 to 3.15, higher than BMI, whose ORs ranged from 1.08 to 2.98. AUCs showed similar ability of TMI (AUC: 0.83) and BMI (AUC: 0.85) in identifying clustered CMRFs. For abdominal obesity and hypertension, the AUC of TMI was 0.92 and 0.64, respectively, which was significantly better than that of BMI, 0.85 and 0.61. AUCs of TMI for dyslipidemia and IFG were 0.58 and 0.49. When 85th and 95th of TMI were set as thresholds, total misclassification rates of TMI for clustered CMRFs ranged from 6.5% to 16.4%, which was not significantly different from that of BMI- z scores standardized according to World Health Organization criteria. CONCLUSIONS TMI was found to have equal or even better effectiveness in comparison with BMI in identifying hypertension, abdominal obesity, and clustered CMRFs TMI was more stable than BMI in 3- to 17-year-old children, while it failed to identify dyslipidemia and IFG. It is worth considering the use of TMI for screening CMRFs in children and adolescents.

Objective:To investigate the effects of thoracic segment epidural anesthesia on inflammatory factors in patients undergoing lung cancer surgery.Methods:The clinical data of 136 patients who underwent lung cancer surgery in the Second People's Hospital of Liaocheng from June 2020 to May 2022 were retrospectively analyzed. According to anesthesia methods, these patients were divided into an observation group ( n = 89) and a control group ( n = 47). The observation group was given thoracic segment epidural anesthesia, while the control group was given remifentanil infusion anesthesia. The tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-10 (IL-10) levels in the epithelial lining fluid collected from the non-dependent lung, the plasma levels of TNF-α, IL-6, and malondialdehyde, arterial partial pressure of oxygen/inhaled oxygen fraction, the incidence of complications, the incidence of re-operations, numeric rating scale score, and the length of hospital stay were compared between the two groups. The effects of different anesthesia methods on lung cancer surgery were evaluated. Results:In each group, TNF-α, IL-6, and IL-10 levels in the epithelial lining fluid were significantly increased 30 minutes after termination of one-lung ventilation (T2) compared with those measured before one-lung ventilation (T1) ( t = 7.71, 77.10, 7.59, 3.41, 57.51, 5.74, all P < 0.05). In the observation group, TNF- α [(1.59 ± 0.53) ng/L, (1.89 ± 0.64) ng/L] measured at T1 and T2, IL-6 [(2.96 ± 0.82) ng/L] and IL-10 [(1.99 ± 0.53) ng/L] measured at T1 were significantly higher compared with those measured at the corresponding time points in the control group ( t = 10.45, 2.59, 2.00, 7.19, all P < 0.05). In the observation group, IL-6 measured at T2 [(38.91 ± 5.84) ng/L] was significantly lower than that in the control group ( t = 33.25, P < 0.001), and IL-10 measured at T2 [(2.51 ± 0.67) ng/L] was slightly, but not significantly higher than that in the control group ( P > 0.05). There was no significant difference in the plasma level of TNF- α measured at T1 and T2 between the two groups (both P > 0.05). Plasma levels of IL-6 in the two groups [(42.98 ± 5.29) ng/L, (27.93 ± 4.17) ng/L] measured at T2 were significantly increased compared with those measured at T1 ( t = 54.14, 61.06, both P < 0.001). In the observation group, TNF-α measured at T2 [(1.60 ± 0.56) ng/L] and IL-6 measured at T1 and T2 [(0.92 ± 0.16) ng/L, (27.93 ± 4.17) ng/L] were significantly lower compared with the control group ( t = 3.39, 6.96, 18.20, all P < 0.05). There were no significant differences in plasma level of malondialdehyde, arterial partial pressure of oxygen/inhaled oxygen fraction, numeric rating scale score, the incidence of complications, the incidence of re-operation, and the length of hospital stay between the two groups (all P > 0.05). Conclusion:Thoracic segment epidural anesthesia can reduce the local inflammatory response of the lung during lung cancer surgery.
