Chinese Journal of School Health 2026;47(2):168-172
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.

OBJECTIVE To compare the efficacy and safety of vedolizumab (VDZ) versus infliximab (IFX) in biologic-naive(Bio-naive) patients with moderate-to-severe active ulcerative colitis (UC), and to analyze the factors influencing efficacy. METHODS Clinical data were retrospectively collected from Bio-naive patients with moderate-to-severe active UC who received treatment in the Department of Gastroenterology at Shanxi Provincial People’s Hospital from June 2023 to June 2024. Based on the type of biologic agent administered, the patients were divided into the IFX group (41 cases) and the VDZ group (30 cases). Patients in the two groups received IFX (5 mg/kg) or VDZ (300 mg) for induction and maintenance of remission therapy. The two groups were compared regarding modified Mayo score, serological indicators (hemoglobin, albumin, platelet count, erythrocyte sedimentation rate, C-reactive protein), combined medication, efficacy-related indexes (clinical response rate/remission rate, and endoscopic response rate/remission rate), and the occurrence of adverse drug reactions (ADR). Based on Logistic regression model, univariate and multivariate analyses were conducted to identify potential factors influencing clinical remission at week 14 and endoscopic remission at week 38. RESULTS There were no statistically significant differences in clinical response rate/remission rate, or endoscopic response rate/remission rate between the two groups at weeks 14 and 38 ( P >0.05). However, at week 14 of treatment, the proportion of patients using concomitant corticosteroids in VDZ group was 26.67%, significantly higher than the 7.50% in IFX group ( P <0.05). There was no statistical significance in the overall incidence of ADR between the two groups ( P >0.05); all ADRs in the IFX group were grade 3 and led to treatment discontinuation (6 cases), whereas ADR in the VDZ group was grade 2 and did not interrupt therapy (1 case). Univariate and multivariate regression analyses revealed that disease type (relapsing) was significantly associated with clinical remission at week 14 of treatment, and a history of smoking was significantly associated with endoscopic remission at week 38 of treatment (the odds ratios were 0.08 for both, with 95% confidence intervals of 0.01-0.77 and 0.01-0.91 respectively, P <0.05). CONCLUSIONS For Bio-naive patients with moderate-to-severe active UC, VDZ and IFX demonstrate comparable efficacy in inducing and maintaining clinical remission and promoting mucosal healing, as well as overall safety. Although IFX can achieve faster control of inflammation in the early stage of the disease, it causes more severe ADR. Disease type (relapsing) and smoking history are identified as independent negative predictors for short-term clinical remission and long-term endoscopic remission, respectively.

The disease-syndrome combination model of spleen deficiency with dampness pattern in ulcerative colitis(SDDP-UC) is an important experimental carrier for traditional Chinese medicine (TCM) research on the prevention and treatment of ulcerative colitis (UC), and the quality of model construction and evaluation directly influences the scientific rigor and translational value of related research conclusions. However, this field still lacks methodological synthesis and a standardized consensus. Based on a comprehensive review of existing literature, this paper summarized isomorphic cues between the spleen deficiency with dampness pattern and UC across four dimensions, including energy metabolism, immune homeostasis, mucosal barrier, and intestinal microecology. The cues were mainly involved in impaired mitochondrial energy supply and glucose metabolic reprogramming, a lowered pro-inflammatory threshold of innate immunity with insufficient adaptive immune regulation, disruption of epithelial barrier gating accompanied by compromised repair capacity, and attenuation of the luminal hypoxia barrier with accumulation of toxic metabolites. A mutually reinforcing process between local "form damage" and systemic "Qi depletion" was further interpreted from a holistic perspective. Regarding modeling strategies, existing studies predominantly use rats as the carrier, apply combined interventions such as improper diet, external damp exposure, and fatigue-related dysregulation to establish the spleen deficiency with dampness pattern background, and subsequently superimpose chemical stimulation to induce UC-like colonic damage, with a total modeling period generally spanning three to four weeks. In terms of the evaluation system, a multidimensional framework integrating syndrome assessment, histopathology, mechanistic indices, and pharmacodynamic counter-verification was outlined. On this basis, current methodological bottlenecks of models were systematically identified, including syndrome drift risk and compounded stress dilemma in temporal sequencing, syndrome confounding from etiological simulation, cross-sectional evaluation bias related to modeling duration, inadequate disease-syndrome linkage and control design within the evaluation system, and limited controls with overly single-track decision logic in formula-based syndrome verification. To address the above issues, a construction and evaluation strategy emphasizing streamlining of core etiological factors, multi-node dynamic monitoring, integration of core disease-syndrome indicator clusters, and establishment of a formula-based syndrome verification system was proposed, providing a reference for the standardized construction and scientific evaluation of the SDDP-UC model.

ObjectiveTo establish the mouse models of psoriasis-like lesions induced by continuous cold exposure or intermittent cold exposure combined with imiquimod (IMQ), and to evaluate the interventional effects of Kaixuan Jiedu core prescription (KXJD) on the two models. MethodsMale C57BL/6J mice were selected and classified into two experimental batches. The first batch of 36 mice was randomized into a room temperature group, a continuous cold exposure (10 ℃/24 h) group, and an intermittent cold exposure (10 ℃/6 h) group. Each group was further divided into a normal subgroup and a model subgroup (topical application of IMQ to induce skin lesions), with 6 mice in each subgroup, for modeling and evaluation. The second batch of 54 mice, with 6 in each group, were subjected to the same temperature grouping with an additional KXJD (30.42 g·kg-1, continuous gavage for 5 days) group. Comprehensive evaluation of model characteristics and KXJD efficacy was conducted through Psoriasis Area and Severity Index (PASI) scoring, skin temperature measurement by infrared thermography, histopathological observation by hematoxylin-eosin (HE) staining, detection of vascular endothelial growth factor (VEGF) and platelet endothelial cell adhesion molecule 1 (CD31) by immunohistochemistry, detection of Claudin-1 and Occludin by immunofluorescence assay, determination of serum levels of tumor necrosis factor-α (TNF-α) and interleukin (IL)-10 by enzyme-linked immunosorbent assay (ELISA), and quantification of mRNA levels of IL-17A, IL-23, IL-6, and chemokine ligand 20 (CCL20) in skin lesions by quantitative Real-time polymerase chain reaction (Real-time PCR). ResultsModel mice in all temperature groups exhibited typical psoriasis-like skin lesions. Compared with the normal groups, the model groups showed increased PASI scores, decreased skin temperatures (P<0.05), obvious epidermal thickening, parakeratosis, and dermal inflammatory cell infiltration, as well as elevated mRNA levels of IL-17A, IL-23, IL-6, and CCL20 (P<0.05). Cold exposure further aggravated psoriasis. The total PASI score of the intermittent cold exposure model group was higher than that of the room temperature model group (P<0.05). The serum IL-10 did not show a compensatory elevation, and the blood vessels presented a characteristic of elevated CD31 expression (P<0.05) without a synchronous increase in VEGF. The continuous cold exposure model group exhibited more significant dermal capillary tortuosity and dilation, with the highest mRNA levels of IL-17A, IL-23, IL-6, and CCL20 among all groups. Compared with the respective model groups, KXJD intervention alleviated skin lesions, reduced epidermal thickness and inflammatory cell infiltration, and increased skin temperature, with the temperature increase being particularly significant in the intermittent cold exposure+KXJD group (P<0.05). Furthermore, KXJD down-regulated the expression of VEGF and CD31, restored the expression of Claudin-1 and Occludin, decreased the mRNA levels of IL-17A and IL-23 (P<0.05), and reduced the serum TNF-α level. ConclusionThis study successfully established compound psoriasis-like mouse models induced by cold exposure combined with IMQ. It confirms that cold aggravates the severity of psoriasis by exacerbating the closure of Xuanfu (sweat pores), microcirculation disorders, and immune imbalance. Moreover, different cold exposure patterns have distinct mechanism differences. Continuous cold exposure focuses on enhancing the inflammatory response via the IL-23/IL-17 axis and angiogenesis, simulating chronic aggravation under a long-term cold environment. Intermittent cold exposure tends to impair immune regulation and induce microvascular endothelial stress, corresponding to acute exacerbations caused by sudden temperature drops. KXJD can effectively alleviate psoriasis-like skin lesions under cold conditions by unblocking Xuanfu, regulating vasomotor function, and correcting abnormal immune-inflammatory responses.

ObjectiveTo investigate the ameliorative effect and potential mechanisms of Kaixuan Jiedu core prescription (KXJD) on imiquimod (IMQ)-combined restraint stress-induced psoriasis-like skin lesions in mice. MethodsA total of 36 C57BL/6J mice were randomly assigned to six groups (n=6 per group): Normal group, restraint stress blank group, model group, restraint stress model group, KXJD group (30.42 g·kg-1), and methotrexate group (0.001 g·kg-1). Psoriasis-like lesions were induced by topical IMQ application combined with restraint stress. After 5 days of intervention, the severity of skin lesions was evaluated using the Psoriasis Area and Severity Index (PASI). The following parameters were assessed: Hypothalamic-pituitary-adrenal (HPA) axis-related hormones, including adrenocorticotropic hormone (ACTH), corticotropin-releasing hormone (CRH), and corticosterone (CORT), central neuronal markers, including neuronal nuclei antigen (NeuN), microtubule-associated protein 2 (MAP2), and beta Ⅲ-tubulin (β-Ⅲ tubulin), microglial activation markers, including ionized calcium-binding adapter molecule-1 (Iba-1) and cluster of differentiation 11b (CD11b), and skin nerve fiber markers, including protein gene product 9.5 (PGP9.5) and serotonin (5-HT), as well as the expression levels of inflammatory cytokines tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-1 beta (IL-1β). ResultsCompared with the normal group, both the model group and the restraint stress model group exhibited more severe psoriasis-like skin lesions, with significantly elevated serum levels of ACTH, CRH, and CORT (P<0.01). The expression of glucocorticoid receptor (GR) and corticotropin-releasing hormone receptor 1 (CRHR1) in the skin was significantly downregulated. The expression of NeuN, MAP2, β-Ⅲ tubulin, Iba-1, and CD11b in the hypothalamus and hippocampus was significantly upregulated, suggesting abnormal changes in neuronal number or structure and aberrant activation of glial cells (P<0.05, P<0.01). In addition, the expression of PGP9.5 and 5-HT in the skin, as well as the mRNA levels of TNF-α, IL-6, and IL-1β were all markedly elevated (P<0.05, P<0.01). Compared with the model group, the restraint stress model group showed further exacerbation in most parameters. Compared with the restraint stress model group, the KXJD group exhibited significantly reduced PASI scores (P<0.01), significantly decreased serum CRH, ACTH, and CORT levels (P<0.05, P<0.01), upregulated skin GR and CRHR1 expression, inhibited abnormal neuronal changes and microglial activation in the hypothalamus and hippocampus, attenuated skin nerve fiber hyperplasia and amine signaling molecule release, and significantly reduced pro-inflammatory cytokine mRNA expression (P<0.05, P<0.01). ConclusionKaixuan Jiedu Core prescription can effectively ameliorate IMQ combined with restraint stress-induced psoriasis-like skin lesions in mice by modulating HPA axis function, inhibiting central neuropathological changes, and attenuating skin nerve fiber hyperplasia, amine signaling molecule (5‑HT) release and local inflammatory responses.

Neurodegenerative diseases are a class of nervous system disorders characterized by delayed onset and selective neuronal dysfunction, which are closely associated with aging.Given the challenges associated with early detection and the irreversible nature of the condition, the pursuit of specific biomarkers has emerged as a critical component of disease prevention strategies.Optical coherence tomography angiography (OCTA) generates images which exhibit near-histological resolution without the requirement for contrast agent injection, demonstrating superior sensitivity compared to fundus photography. OCTA has the ability to identify and evaluate neurodegenerative diseases via the quantitative analysis of retinal parameters. The OCTA of the retina and choroid has been verified as a highly sensitive instrument for detecting microvascular abnormalities in both ocular and systemic retinal disorders. This review focuses on the application of OCTA in various neurodegenerative diseases, such as Alzheimer′s disease, Parkinson disease, Huntington′s disease, amyotrophic lateral sclerosis and Wolfram syndrome, with the aim of providing a reference for the early diagnosis and prevention of neurodegenerative diseases.

Objective:To conduct a scoping review on the current status, assessment tools and influencing factors of malnutrition in elderly stroke patients, so as to provide new ideas for the development of individualized nutritional intervention programs.Methods:Studies related to malnutrition in elderly stroke patients were searched in China National Knowledge Infrastructure, VIP, WanFang Data, China Biology Medicine disc, PubMed, Web of Science, Embase and Clinical Trial Registration Center. The search period was from the establishment of the database to January 2024. Two researchers independently screened the literature, extracted information based on inclusion and exclusion criteria, and finally categorized and reported the findings.Results:A total of 33 papers were included. In elderly stroke patients, the prevalence of malnutrition varied between studies. There was a wide range of tools to assess the nutritional status of patients, but there was an overall lack of multidimensional and specific tools. Commonly used was the Short-form Mini-nutritional Assessment. Factors influencing malnutrition in patients included general demographic, disease-related and lifestyle factors, physiologic and biochemical indicators, functional correlates, nutrient literacy-related factors, psychological and supportive factors.Conclusions:Malnutrition in elderly stroke patients is influenced by a variety of factors and seriously affects patient prognosis. Standardized assessment tools should be adopted to detect timely and accurately, take targeted measures for each factor, and carry out personalized intervention programs to promote benign changes in the nutritional status of elderly stroke patients.

Objective:To identify the change trajectory of intrinsic capacity in people aged ≥50 years in Shanghai and explore the impact of intrinsic capacity trajectory change on overall function and dalily life activities in this population.Methods:The longitudinal data from round 1 to 3 Study of Global Ageing and Adult Health in Shanghai were used. The total intrinsic ability scores from five dimensions of cognition, psychology, sensory, vitality and locomotion were calculated. The censored normal model of group-based trajectory was used to identify the trajectory of intrinsic capacity change over time. Linear regression model and multivariate logistic regression model were used to analyse the effects of different levels intrinsic capacity trajectory on the scores of the WHO Disability Assessment Schedule (WHODAS), the activity of daily living (ADL) and the instrumental activities of daily living (IADL).Results:A total of 2 302 study participants aged ≥50 years with 3 round complete data were included in this study, and 3 levels of intrinsic capacity trajectory were identified, low-level trajectory (9.3%), medium-level trajectory (41.7%), and high-level trajectory (49.0%). Compared with the high-level group, the medium-level and low-level groups had higher WHODAS scores, which increased by 3.578 (95% CI: 2.028-5.129) and 12.620 (95% CI: 9.951-15.289), respectively, and those with more severe disability and those in the low-level group were at higher risk for severe difficulty in ADLs ( OR=12.450, 95% CI: 4.310-35.966) and IADLs ( OR=5.479, 95% CI: 1.311-22.904). Conclusions:Heterogeneity in trajectory of intrinsic capacity exists in people aged ≥50 years in Shanghai. Middle-aged and elderly people with low initial level and rapid decline trajectory of intrinsic capacity are at greater risk for the decline of daily life ability and the increase of disability. It is necessary to strengthen the long-term dynamic monitoring and evaluation of the change trajectory of intrinsic capacity in this population.

Objective:To explore patterns of traditional Chinese medicine (TCM) use among patients with inflammatory bowel disease (IBD) in Jiangsu Province, China from 2019 to 2023.Methods:Using data from the IBD health data platform of the National Healthcare Big Data (Eastern) Center, a retrospective cohort study was conducted. We performed descriptive analyses on hospitalised patients diagnosed with IBD between 2019 and 2023, who received TCM treatment.Results:The study included 11 095 case records from 4 760 patients, with TCM diagnoses primarily indicating diarrhoea and abdominal pain. Ulcerative colitis (UC) accounted for 4 782 hospitalizations (3 103 patients), while Crohn's disease (CD) accounted for 6 313 hospitalizations (1 657 patients). Patient demographics showed a trend towards younger age and a higher proportion of males. Treatment utilisation was highest in southern Jiangsu compared with the central and northern regions. In terms of disease burden, all treatment costs showed a downward trend. In terms of external TCM therapies, UC patients tend to prefer plasters and enemas, while CD patients are more inclined to use acupuncture. Regarding herbal medicine, licorice, white atractylodes, and white peony root are commonly used single herbs for IBD patients.Conclusions:The number of IBD patients treated with TCM in Jiangsu Province has steadily increased from 2019 to 2023. It is important to identify effective TCM treatment methods to reduce the burden of patients.
