Objective To analyze the epidemiological characteristics of statutory infectious diseases in Yichang City from 2015 to 2023 and evaluate the effectiveness of non-pharmaceutical interventions (NPIs) in infectious disease prevention and control, and to provide a basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze annual incidence rates. SARIMA and SARIMA intervention models were constructed to predict the incidence rates of infectious diseases. Interrupted time series analysis (ITS) was applied to assess the control effectiveness. Results The average annual incidence rate from 2015 to 2023 was 787.47/100 000, with the top five diseases being influenza, hand-foot-and-mouth disease, hepatitis B, tuberculosis, and diarrheal diseases. The average incidence rate from 2015 to 2019 (654.31/100 000) was significantly higher than that from 2020 to 2022 (489.01/100 000) (χ²= 3 499.6, P < 0.05). The total incidence rate in 2023 (2 396.51/100 000) was significantly higher than the average annual incidence rates from 2015-2019 (χ²= 108 186.1, P < 0.05) and 2020-2022 (χ²= 112 869.4, P < 0.05). SARIMA model results indicated that the actual incidence rate from 2020 to 2022 decreased by 73.49% compared to the predicted rate without intervention, with the highest decline observed in respiratory infectious diseases (79.57%). The SARIMA-intervention model showed a 55.48% relative decrease in the total incidence rate for 2023, with the largest reduction in respiratory infectious diseases (63.28%) and a slight increase in intestinal infectious diseases (5.48%). Conclusion NPIs effectively reduce the incidence of statutory infectious diseases in the short term, especially for acute respiratory and intestinal infectious diseases. However, long-term effectiveness faces challenges, necessitating the development of differentiated prevention and control strategies.

BACKGROUND: There is growing evidence that the occurrence and severity of respiratory diseases in children are related to the concentration of air pollutants. Nonetheless, evidence regarding the association between short-term exposure to air pollution and outpatient visits for respiratory diseases in children remains limited. Outpatients cover a wide range of disease severity, including both severe and mild cases, some of which may need to be transferred to inpatient treatment. This study aimed to quantitatively evaluate the impact of short-term ambient air pollution exposure on outpatient visits for respiratory conditions in children. METHODS: This study employed data of the Second People's Hospital of Yichang from January 1, 2016 to December 31, 2023, to conduct a time series analysis. The DLNM approach was integrated with a generalized additive model to examine the daily outpatient visits of pediatric patients with respiratory illnesses in hospital, alongside air pollution data obtained from monitoring stations. Adjustments were made for long-term trends, meteorological variables, and other influencing factors. RESULTS: A nonlinear association was identified between PM_2.5, PM₁₀, O₃, NO₂, SO₂, CO levels and the daily outpatient visits for respiratory diseases among children. All six pollutants exhibit a hysteresis impact, with varying durations ranging from 4 to 6 days. The risks associated with air pollutants differ across various categories of children's respiratory diseases; notably, O₃ and CO do not show statistical significance concerning the risk of chronic respiratory conditions. Furthermore, the results of infectious respiratory diseases were similar with those of respiratory diseases. CONCLUSIONS Our results indicated that short-term exposure to air pollutants may contribute to an increased incidence of outpatient visits for respiratory illnesses among children, and controlling air pollution is important to protect children's health.

The research of damp-heat syndrome in modern TCM mainly focuses on inflammatory response, water metabolism, lipid metabolism, hemorheology, intestinal flora and so on. Modern omics techniques such as metabolomics and genomics provide a new perspective for the exploration of the micro-mechanism of damp-heat syndrome. The study found that the abnormal expression of aquaporin is closely related to the formation of "dampness" in damp-heat syndrome, and the release of inflammatory factors reflects the pathological characteristics of "heat". Damp-heat syndrome is often accompanied by dyslipidemia, hemorheological changes and intestinal flora imbalance, showing characteristic changes in urine, blood and saliva metabolomics, and there are differences in gene expression between damp-heat constitution and gentleness constitution. In the future, the pertinence and systematicness of research should be strengthened, the relationship between indicators should be deeply explored, build a biomarker system should be built, the immune-metabolic regulation mechanism should be explored, the multi-target mechanism of heat-clearing and dampness-removing Chinese materia medica should be clarified to further improve the damp-heat syndrome system, and provide theoretical support for clinical treatment.

Objective:To analyze the clinical characteristics of inconsistent symptoms and signs of dry eye in patients with Sj?gren syndrome (SS).Methods:A case-control study was performed.Thirty-eight patients (38 eyes) who visited the dry-eye outpatient department at Peking University People's Hospital were enrolled from January to October 2021.The patients were divided into a non-SS (NSS) group (25 cases, 25 eyes) and a SS group (13 cases, 13 eyes) according to without or with SS.The data of right eyes were analyzed.The patients' subjective symptoms were scored and their objective clinical parameters were evaluated.Evaluation of subjective symptoms included Ocular Surface Disease Index (OSDI), Standard Patient Evaluation of eye dryness (SPEED) Questionnaire and Dry Eye Questionnaire-5 (DEQ-5).Objective clinical parameters included Schirmer Ⅰ test (SⅠt), tear film breakup time (TBUT), SICCA ocular staining score (OSS), National Eye Institute (NEI) score, Marx line score, non-invasive tear film breakup time (NIBUT), non-invasive tear meniscus height (NITMH), meibomian gland loss area ratio, the number of corneal subepithelial nerves, total nerve length, mean nerve length, maximum nerve length, minimum nerve length, nerve curvature, and number of dendritic cells.Differences in subjective symptoms and clinical parameters were compared between the two groups, and correlation analysis between ocular symptom scores and objective clinical parameters was performed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Peking University People's Hospital (No.RDY2020-03).Written informed consent was obtained from each subject.Results:The OSDI, SPEED and DEQ-5 scores of SS group were 10.9(2.1, 23.1), 4.0(2.0, 7.0) and 7.0(3.5, 9.5), respectively, which were significantly lower than 37.5(26.0, 64.9), 10.5(7.0, 13.0) and 13.0(6.8, 14.3) of NSS group ( Z=-2.70, -3.01, -2.14; all P<0.05).TBUT was longer in the SS group than in the NSS group, and the difference was statistically significant ( Z=-2.10, P=0.038).No significant difference was found in SⅠt, OSS, Marx line score, NIBUT, NITMH, meibomian gland loss area ratio, the number of corneal subepithelial nerves, total nerve length, mean nerve length, maximum nerve length, minimum nerve length, nerve curvature, and number of dendritic cells (all P>0.05).The OSS of nasal conjunctiva was significantly higher in the SS group than in the NSS group ( Z=-2.32, P=0.023).There were no correlations between the subjective symptoms and objective clinical parameters in NSS group (all P>0.05).The SPEED score was positively correlated with the Marx line score of upper eye lid ( rs=0.573, P=0.041) and the OSDI score was negatively correlated with the minimum nerve length ( rs=-0.606, P=0.037) in SS group. Conclusions:Patients with SS dry eye have more nasal conjunctival staining and fewer subjective symptoms than NSS dry eye patients with the same signs, which manifests as a separation of symptoms and signs.
