Objective: To understand the microclimate in primary and secondary school classrooms for the study period during the winter heating season, so as to provide a reference for the revision and improvement of relevant health standards. Methods: In December 2024, stratified random sampling was used to select 30 primary and secondary schools and 180 classrooms from the northern regions with centralized heating (Liaoning Province, Tianjin City) and the southern regions without centralized heating (Shanghai City, Anhui Province, and Jiangxi Province). Indoor temperature, relative humidity, wind speed, CO 2 and other indicators were measured on site. Variance analysis, t-test, Mann-Whitney U test and Kruskal-Wallis H test were used to analyze the differences in the microclimate of classrooms among regions and urban and rural differences. Results: The average temperature in the middle of the classrooms tested on site was (16.47±4.72)℃, and the variance analysis showed that the difference between the regions was statistically significant ( F=27.80, P <0.01). Among them, Tianjin had the highest average temperature of (20.43± 2.12 )℃, followed by Liaoning (19.03±2.23)℃, Shanghai (15.33±5.32)℃, Anhui (12.79±1.74)℃, and Jiangxi (11.69± 1.68 )℃. Horizontal temperature difference was 0.90 (0.50, 1.60)℃, the vertical temperature difference was 0.20 (0.10,0.60)℃, the average relative humidity was (44.39±16.16)%, the wind speed was 0.03(0.01,0.11)m/s, and the differences among different provinces and cities were statistically significant ( H/F =40.62, 82.69, 95.06, 55.28, all P <0.01). The average CO 2 volume concentration in urban areas of Tianjin, Liaoning, and Shanghai was 0.21(0.16,0.30)%, and there was no statistically significant difference ( H=4.65, P =0.10). There were grade differences in relative humidity ( F =3.71, 6.21) and CO 2 ( H =14.72, 12.92) in the north and the south (all P <0.05). In addition, the temperature, relative humidity, wind speed and CO 2 in the middle of the classroom were 42.8%, 67.8%, 100.0% and 22.2% respectively. Conclusions The temperature in the middle of the classroom in the non centralized heating area is lower than the standard, the relative humidity of classroom in the centralized heating area is lower than the standard，and the CO 2 in the classroom in winter is lower than the standard. It is recommended to install heating facilities in schools with low temperatures to increase the temperature and increase the frequency of ventilation in classrooms or adopt mechanical ventilation strategies to reduce CO 2 volume concentration.

Objective: To evaluate the current situation of thermal environment in primary and secondary school classrooms during winter, and to analyze students thermal comfort needs, so as to provide a basis for improving classroom thermal environment. Methods: From December 16 to 26, 2024, a stratified cluster random sampling method was used to select 90 classrooms from 15 primary and secondary schools in centralized/air conditioned heating areas(Liaoning Province, Tianjin City, Shanghai City) and naturally ventilated areas(Anhui Province and Jiangxi Province)for on site environmental measurement. A questionnaire survey was conducted among 743 students. The differences between groups using the χ 2 test were compared. Based on actual measurement data, a predicted mean vote prepared percentage of dissatisfied (PMV-PPD) model for centralized/air conditioned classrooms and an adaptive model for naturally ventilated classrooms were established, and the thermal neutral temperature and comfort interval were calculated. Results: The average outdoor temperature during on site measurement was 4.00(0.20，7.00)℃. In classrooms with centralized or air conditioned heating systems, the measured average temperature was (19.33±2.59)℃, with a thermal comfort range of 20.35-25.35 ℃ and a thermal neutral temperature of 22.85 ℃. And 13.92% of students reported feeling cold, while 80.80% felt comfortable. In classrooms with natural ventilation, the measured average temperature was (12.26±1.83)℃, with a thermal neutral temperature of 19.67 ℃ and a thermal comfort range of 16.17-23.17 ℃. About 48.33% of students reported feeling cold, and 49.81 % felt comfortable.The results of univariate analysis showed that there were statistically significant differences in shoe thickness, temperature sensation, relative humidity sensation and wind speed sensation between centralized/air conditioned heating areas ( χ 2= 7.01 , 31.47, 13.57, 13.80,all P <0.05). There were also statistically significant differences in school stage for primary and secondary school students, body mass index, classroom location for seat, temperature sensation, relative humidity sensation and wind speed sensation between naturally ventilated areas ( χ 2=42.13, 11.13, 11.04, 60.39, 29.27, 38.46,all P <0.05). Conclusions There are differences in thermal environment and students subjective thermal comfort in primary and secondary schools under different ventilation modes in winter. The temperature standards for heated classrooms should be revised, and differentiated environmental regulation strategies should be adopted based on different ventilation methods to improve students health and comfort levels.

This paper summarizes professor TU Jinwen's clinical experience in treating cancer-related insomnia （CRI） based on different qi and fire. It is believed that the pathogenesis of CRI can be divided into three stages. At the initial stage， qi movement is constrained， while the strong fire begins to stir， and the sovereign fire is unsettled， when qi is abundant， but the fire is not excessive. For this， Sanhua Jieyu Anshen Decoction （三花解郁安神汤） is suggested， which can move qi and vent constraint， clear and diffuse strong fire， calm the heart and spirit. At the progressive stage， strong fire becomes intense and burning， and qi transformation weakens， with toxin fire harassing the spirit. This is the stage where both qi and fire are excessive， for which Huanglian Jiedu Anshen Decoction （黄连解毒安神汤） can be used to clear and dissipate strong fire， drain fire and resolve toxin， clear heart and calm spirit. At the terminal stage， strong fire subsides， and consumption of qi damages healthy qi， with failure of nourishment of heart spirit， when both qi and fire deplete. Correspondingly， Erren Yangxin Anshen Decoction （二仁养心安神汤） is used to boost qi and nourish yin， restore interaction between the heart and the kidney， nourish the heart and calm spirit.

Zhishi Shaoyaosan is the 34^th prescription in the Catalogue of Ancient Classic Formulas （Second Batch） published by the National Administration of Traditional Chinese Medicine in 2023. It is widely used in clinical practice and has a definite curative effect. However， there is currently a lack of its ancient literature analysis and textual research， and there is no corresponding Chinese patent medicine preparation. By consulting and combing the relevant ancient books of traditional Chinese medicine， this paper analyzes and conducts textual research of the origin， composition， measurement， administration， and efficacy of Zhishi Shaoyaosan. The results show that Zhishi Shaoyaosan is derived from Essentials from the Golden Cabinet written by Zhang Zhongjing in the Eastern Han Dynasty. It is mainly recorded in the name of Zhishi Shaoyaosan in the literature of the past dynasties. The prescription is composed of Aurantii Fructus Immaturus and Paeoniae Radix Alba. The processing method is stir-frying Aurantii Fructus Immaturus to scorch and using raw Paeoniae Radix Alba. The dose of the prescription recorded in the ancient books is mainly an equal amount of Aurantii Fructus Immaturus and Paeoniae Radix Alba in one square-cun spoon， taken three times a day， which is converted into a modern dose of 1.5 g each time （0.75 g Aurantii Fructus Immaturus and 0.75 g Paeoniae Radix Alba each time）. The components of the prescription are ground into powder and taken with barley porridge， three times a day. The efficacy is to break stagnated Qi， harmonize blood， and relieve restlessness and pain. It is mainly used to treat postpartum abdominal pain， acute pelvic inflammatory disease， acute cholecystitis and intestinal diseases， stroke sequelae， and other diseases. This study combs and analyzes the ancient literature recording Zhishi Shaoyaosan and clarifies the key information of the prescription， which provides a basis for promoting the research and development of its patent medicine.

Objective:To develop and externally validate a nomogram prediction model for assessing the risk of treatment dropout in allergic rhinitis (AR) patients undergoing sublingual immunotherapy (SLIT).Methods:Between February 2016 and December 2019, data from 358 and 259 AR patients undergoing SLIT were collected from Guizhou Provincial People′s Hospital and Huangshi Central Hospital, respectively. The data included general patient information, dust mite sIgE levels, allergen types, and 22 other clinical variables. Data from Guizhou Provincial People′s Hospital were used as the training set, while data from Huangshi Central Hospital were served as the external validation set. A multivariable Cox regression model was used to identify independent factors associated with SLIT dropout and to develop a nomogram prediction model.Results:Multivariate Cox regression analysis identified several significant factors influencing SLIT dropout, including dust mite sIgE levels (Grade Ⅱ-Ⅳ; HR=1.48, 95% CI: 1.16-1.88), presence of other allergic diseases ( HR=0.47, 95% CI: 0.37-0.61), Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) score ( HR=0.98, 95% CI: 0.97-1.00), WeChat management ( HR=0.77, 95% CI: 0.60-0.98), treatment efficacy ( HR=0.72, 95% CI: 0.56-0.92), age (5-17 years, HR=0.50, 95% CI: 0.36-0.71;≥60 years, HR=1.42, 95% CI: 1.08-1.87), household income (<5 000 CNY, HR=1.44, 95% CI: 1.09-1.90;>20 000 CNY, HR=0.66, 95% CI: 0.44-0.99), allergen types (single dust mite, HR=0.70, 95% CI: 0.49-0.93; and combined pollen or mold, HR=1.45, 95% CI: 1.02-2.04), and time to efficacy <3 months ( HR=0.73, 95% CI: 0.56-0.94), all P<0.05. At the third-year follow-up, the area under curve (AUC) for the nomogram model was 0.913 (95% CI: 0.881-0.943) in the training group and 0.886 (95% CI: 0.838-0.933) in the validation group. Calibration and decision curve analyses demonstrated the model′s consistency with actual dropout rates and clinical benefit in both groups. Additionally, a Brier score of 0.29 further confirmed the model′s predictive accuracy. Conclusion:We successfully develop a nomogram-based prediction model for SLIT dropout in AR patients, which could assist healthcare professionals in effectively identifying high-risk patients and facilitate the development of more personalized and timely treatment plans aimed at enhancing patient compliance.

AIM To investigate the effects of Huazhuo Jiedu Shugan Formula(HJSGF)on improving learning and memory impairment in a rat model of vascular dementia(VD)via SIRT1/PGC-1α/PPARγ pathway.METHODS The SD rats were randomly divided into the sham control group,the model group,the donepezil group(0.5 mg/kg),and the low-,medium-and high-dose HJSGF groups(2.7,5.4,10.8 g/kg),with 10 rats in each group.The VD rat models established by bilateral common carotid artery permanent ligation(2-VO)had their neurological behavior assessment using the Longa5-point scale,and their modeling success confirmed by the Morris water maze test and their 3-week corresponding dosing of drugs by gavage afterward.After the drug administration,the rats had their spatial memory ability tested through behavioral experiments;their serum levels of IL-18 and IL-1β measured by ELISA;their histopathological changes and neuronal morphology in the hippocampal CA1 region observed by HE staining and Nissl staining;and their hippocampal protein expressions of SIRT1,PGC-1α and PPARγ detected by immunohistochemistry and Western blot.RESULTS Compared with the sham control group,the model group showed prolonged escape latency(P＜0.01);decreased platform crossing times and target quadrant residence time(P＜0.01);disorganized arrangement of hippocampal CA1 neurons,nuclear condensation,reduced Nissl bodies,increased secretion and protein expressions of IL-1β and IL-18(P＜0.01);and reduced hippocampal protein expressions of SIRT1,PGC-1α and PPARγ(P＜0.01).Compared with the model group,the groups intervened with donepezil or HJSGF showed shortened escape latency(P＜0.05,P＜0.01);increased platform crossing times and target quadrant residence time(P＜0.05,P＜0.01);alleviated damage of the hippocampal CA1 region,reduced secretion and protein expressions of IL-1β and IL-18(P＜0.05,P＜0.01);and elevated hippocampal protein expressions of SIRT1,PGC-1α and PPARγ(P＜0.05,P＜0.01).CONCLUSION HJSGF may alleviate the inflammatory responses in VD rats and therefore improve their learning and memory impairment by activating the SIRT1/PGC-1α/PPARγ signaling pathway.

BACKGROUND: Both medication and non-medication therapies are effective approaches to control blood pressure (BP) in hypertension patients. However, the association of joint changes in antihypertensive medication use and healthy lifestyle index (HLI) with BP control among hypertension patients is seldom reported, which needs to provide more evidence by prospective intervention studies. We examined the association of antihypertensive medication use and HLI with BP control among employees with hypertension in China based on a workplace-based multicomponent intervention program. METHODS: Between January 2013 and December 2014, a cluster randomized clinical trial of a workplace-based multicomponent intervention program was conducted in 60 workplaces across 20 urban areas in China. Workplaces were randomly divided into intervention (n = 40) and control (n = 20) groups. Basic information on employees at each workplace was collected by trained professionals, including sociodemographic characteristics, medical history, family history, lifestyle behaviors, medication status and physical measurements. After baseline, the intervention group received a 2-year intervention to achieve BP control, which included: (1) a workplace wellness program for all employees; (2) a guidelines-oriented hypertension management protocol. HLI including nonsmoking, nondrinking, adequate physical activity, weight within reference range and balanced diet, were coded on a 5-point scale (range: 0-5, with higher score indicating a healthier lifestyle). Antihypertensive medication use was defined as taking drug within the last 2 weeks. Changes in HLI, antihypertensive medication use and BP control from baseline to 24 months were measured after the intervention. RESULTS: Overall, 4655 employees were included (age: 46.3 ± 7.6 years, men: 3547 (82.3%)). After 24 months of the intervention, there was a significant improvement in lifestyle [smoking (OR = 0.65, 95% CI: 0.43-0.99; P = 0.045), drinking (OR = 0.52, 95% CI: 0.40-0.68; P < 0.001), regular exercise (OR = 3.10, 95% CI: 2.53-3.78; P < 0.001), excessive intake of fatty food (OR = 0.17, 95% CI: 0.06-0.52; P = 0.002), restrictive use of salt (OR = 0.26, 95% CI: 0.12-0.56; P = 0.001)]. Compare to employees with a deteriorating lifestyle after the intervention, those with an improved lifestyle had a higher BP control. In the intervention group, compared with employees not using antihypertensive medication, those who consistent used (OR = 2.34; 95% CI: 1.16-4.72; P = 0.017) or changed from not using to using antihypertensive medication (OR = 2.24; 95% CI: 1.08-4.62; P = 0.030) had higher BP control. Compared with those having lower HLI, participants with a same (OR = 1.38; 95% CI: 0.99-1.93; P = 0.056) or high (OR = 1.79; 95% CI: 1.27~2.53; P < 0.001) HLI had higher BP control. Those who used antihypertensive medication and had a high HLI had the highest BP control (OR = 1.88; 95% CI: 1.32-2.67, P < 0.001). Subgroup analysis also showed the consistent effect as the above. CONCLUSION These findings suggest that adherence to antihypertensive medication treatment and healthy lifestyle were associated with a significant improvement in BP control among employees with hypertension.

Coronavirus-related diseases pose a significant challenge to the global health system. Given the diversity of coronaviruses and the unpredictable nature of disease outbreaks, the traditional "one bug, one drug" paradigm struggles to address the growing number of emerging crises. Therefore, there is an urgent need for therapeutic agents with broad-spectrum anti-coronavirus activity. Here, we provide evidence that ATV006, an anti-SARS-CoV-2 nucleoside analog targeting RNA-dependent RNA polymerase (RdRp), has broad antiviral activity against human and animal coronaviruses. Using mouse hepatitis virus (MHV) and human coronavirus NL63 (HCoV-NL63) as a model, we show that ATV006 has potent prophylactic and therapeutic activity against murine coronavirus infection in vivo. Remarkably, ATV006 successfully inhibits viral replication in mice even when administered 96 h after infection. Due to its oral bioavailability and potency against multiple coronaviruses, ATV006 has the potential to become a useful antiviral agent against SARS-CoV-2 and other circulating and emerging coronaviruses in humans and animals.

Objective:To analyze the distribution characteristics of sports facilities in China using geographic information system (ArcGIS) and to investigate their association with mortality risk among residents.Methods:This prospective cohort study included 97 912 community residents from the Chinese Family Database (CFD) between 2013 and 2017. After excluding participants lost to follow-up and those with incomplete data, 53 937 individuals were retained for the analysis. The distribution characteristics of sports facilities in China was mapped using ArcGIS, and the death events were recorded via structured interviews and questionnaires. The Poisson regression was used to assess the association between the distribution characteristics of sports facilities near participants′ residences and their mortality risk.Results:In 2013, a total of 79 714 sports facilities were identified across 262 districts (counties) in China, with large-scale sports facilities accounting for the highest proportion (87.09%). The median number of sports facilities within the residential buffer zone was 17 (4, 30), and the median distance from the residence to the nearest sports facility was 453.2 (341.5, 1 863.5) m. Among the 53 937 community residents analyzed in this study, there were 27 761 males and 26 176 females, 1 326 deaths (2.5%) occurred during the follow-up. Poisson regression revealed that a higher number of sports facilities in the buffer zone (≥21 vs 0-2) was associated with lower mortality risk ( RR=0.74, 95% CI: 0.64-0.85; P0.05). Subgroup analyses showed that being≥60 years old ( RR=0.82, 95% CI: 0.70-0.95), males ( RR=0.78, 95% CI: 0.64-0.95), females ( RR=0.79, 95% CI: 0.64-0.97), having a junior high school education or less ( RR=0.84, 95% CI: 0.71-0.99), and having a urban residence ( RR=0.77, 95% CI: 0.66-0.90) were all negatively associated with residents′ mortality risk (all P0.05). After adjusting for age, greater distance to the nearest sports facility ( RR=1.41, 95% CI: 1.08-1.83) and failing to meet the"10-minute fitness circle"criterion ( RR=1.25, 95% CI: 1.02-1.53) were associated with higher mortality risk among males (both P0.05). After adjusting for age and gender, urban residents with a greater distance to the nearest sports facility ( RR=1.29, 95% CI: 1.04-1.60) or not meeting the 10-minute fitness circle ( RR=1.18, 95% CI: 1.00-1.38) showed a significantly higher mortality risk (both P0.05). Conclusions:The ArcGIS analysis revealed that the distribution of sports facilities in China is characterized by a high proportion of large-scale facilities. Lower facility density within residential buffer zone and greater distance to the nearest facility increase mortality risk among adults.

Objective To extract and summarize the clinical registration information of periodontitis registered in the US ClinicalTrials.gov and Chinese Clinical Trial Registry(ChiCTR),and further analyze the registration characteristics of periodontitis clinical trials.Methods The ClinicalTrials.gov and ChiCTR data-bases were searched and compiled for periodontitis clinical registration information from 2000 to December 26,2024,including registration number,country/region of registration,annual number of registered projects,sample size,study type and design,study phase,and trial progress status.Results As of December 26,2024,a total of 520 242 registered clinical trials were retrieved from the ClinicalTrials.gov registry platform,of which 1 542(0.30%)were related to periodontitis.There were 189(12.26%)studies on periodontitis-related pro-jects in Turkey,while a total of 37(2.4%)projects were initiated by researchers in China,which ranked ninth.The Chinese Clinical Trial Register(ChiCTR)had 92 954 registered projects,of which 165 were on pe-riodontitis,and most of them were conducted by well-known affiliated hospitals and stomatology hospitals.The number of registrations in the ClinicalTrials.gov database increased year by year and reached a peak in 2022(146 registrations).Trial designs were focused on interventional and observational studies.ClinicalTri-als.gov study phases were focused on phases 2 and 4,while ChiCTR was clustered at phase 0(pre-registra-tion).Conclusion The number of clinical registrations for periodontitis in China's database is relatively low,and despite a steady upward trend,there is still a gap compared with other countries internationally.Future re-search should focus on how to encourage more oral health related research institutions to register on the plat-form and how to increase the sample size.
