Objective: To investigate the epidemiological characteristics of pertussis in Jiaxing City from 2004 to 2023 and spatio-temporal clustering characteristics from 2022 to 2023, so as to provide insights into formulation of pertussis control measures. Methods: Data of pertussis cases in Jiaxing City from 2004 to 2023 were collected through the Infectious Disease Report Information System of Chinese Disease Prevention and Control Information System. The epidemiological characteristics of pertussis cases in Jiaxing City from 2004 to 2023 were descriptively analyzed, and the spatio-temporal clustering characteristics from 2022 to 2023 were analyzed using spatio-temporal scanning. Results: A total of 478 pertussis cases were reported in Jiaxing City from 2004 to 2023, with an average annual reported incidence of 0.53/105. The reported incidence showed an upward trend from 2004 to 2023 (P<0.05), with the highest in 2022 (3.17/105). Higher incidence of pertussis was reported in June to August (149 cases, 31.17%) and November to December (112 cases, 23.43%). There was no statistically significant difference in the reported incidence between males and females (0.56/105 vs. 0.50/105, P>0.05). The cases aged under one year accounted for the highest proportion, with 199 cases (41.63%). Haining City (0.68/105), Jiashan County (0.64/105) and Tongxiang City (0.60/105) ranked the top three in the reported incidence of pertussis. Spatio-temporal scanning analysis showed that from 2022 to 2023, the primary clustering area of pertussis was centered in Daqiao Town of Nanhu District, covering 27 towns (streets) in Nanhu District, Jiashan County, Xiuzhou District and Pinghu City, and the clustering time was from November to December, 2023. Conclusions The reported incidence of pertussis was at a low level in Jiaxing City, but showed an upward trend from 2004 to 2023. The incidence of pertussis was higher among infants under one year of age, peaked in June to August and November to December, and was concentrated in Nanhu District and its surrounding areas.

Objective: To explore the association between physical activity, anxiety symptoms and academic performance among junior high school students, so as to provide data support for optimizing school physical education and health work and formulating physical activity guidelines. Methods: From September to December 2022, a convenience cluster sampling method was used to survey 2 800 junior high school students in a middle school from Anqing City, Anhui Province. Data were collected on the students anxiety symptoms, academic performance, 24 hour physical activity [moderate to vigorous intensity physical activity(MVPA), light intensity physical activity(LPA), sedentary behavior(SB), and sleep(SLP) duration] as well as demographic characteristics. Compositional data analysis was used to explore the associations between 24 hour physical activity, anxiety symptoms and academic performance among junior high school students, and to predict the optimal time use combination pattern. Results: Among the junior high school students, 16.0% (447 students) reported anxiety symptoms, and 42.0% (1 175 students) achieved excellent or good academic performance. Compositional data analysis showed that increased SLP duration was associated with both reduced anxiety symptoms ( β =-0.18) and decreased academic performance ( β =-0.03) among junior high school students; increased MVPA duration was correlated with fewer anxiety symptoms ( β =-0.02) and lower academic performance ( β =-0.13); in contrast, increased SB duration was linked to more anxiety symptoms ( β =0.09) and higher academic performance ( β =0.09) (all P <0.01). LPA duration exhibited a non linear relationship with anxiety symptoms and academic performance in junior high school students (all P >0.05). The time use combination pattern corresponding to the lowest anxiety symptoms and highest academic performance (top 5%) in adolescents was 611 (520-640) minutes of SLP, 258 (230-320) minutes of SB, 454 (280-610) minutes of LPA, and 117 (20-200) minutes of MVPA per day. Conclusions The 24 hour physical activity of junior high school students is associated with anxiety symptoms and academic performance. Therefore, it is recommended to increase the time spent on SB, MVPA, and LPA for junior high school students, while reducing SB.

Objective To investigate the effect of the long noncoding RNA(lncRNA)FGD5-AS1 on the migration and invasion of gas-tric cancer cells by regulating the miR-133a-3p/SPAG5 axis.Methods Quantitative real-time PCR was used to detect FGD5-AS1,miR-133a-3p,and SPAG5mRNA expression in gastric cancer tissues and adjacent non-tumor tissues,the normal human gastric epithelial cell line GES-1,and gastric cancer cell lines(MKN-28 and NCI-N87,HGC-27,and AGS).Cell counting kit-8 method and 5-ethynyl-2-de-oxyuridine(EdU)staining were performed to detect cell proliferation.Transwell assays were performed to assess cell invasion.A scratch assay was performed to detect the migration ability.Western blotting was performed to detect the expression of the proliferative proteins Ki-67,SPAG5,migration,invasion enhancer factor 1(MIEN1),and matrix proteinase-9(MMP-9).A double-luciferase assay was used to confirm the relationship between miR-133a-3p,FGD5-AS1,and SPAG5expression.Results FGD5-AS1 and SPAG5mRNA levels were significantly elevated in gastric cancer tissues and cell lines,whereas miR-133a-3p was significantly reduced(P<0.05),with the most significant gene changes observed in MKN-28 cells(P<0.05).Compared with the blank and siNC groups,FGD5-AS1,SPAG5mRNA,EdU-positive rate,proliferative,invasive,and migratory abilities,Ki-67,MIEN1,SPAG5,and MMP-9 expression in the siFGD5-AS1 group decreased,and the expression of miR-133a-3p increased(P<0.05).Compared to the siFGD5-AS1+inhibitor NC group,the expres-sion of SPAG5mRNA;proliferative,invasive,and migratory abilities;and Ki-67,MIEN1,SPAG5,and MMP-9 expression in the siFGD5-AS1+miR-133a-3p inhibitor group increased,and the expression of miR-133a-3p decreased(P<0.05).Conclusion Interference with lncRNA RNA FGD5-AS1 can inhibit the migration and invasion of gastric cancer cells by upregulating the miR-133a-3p/SPAG5 axis.

Objective:To explore the feasibility of using a simplified multiple sleep latency test (MSLT) for the diagnosis of narcolepsy type 1.Methods:Data from 158 patients with narcolepsy type 1 and 58 patients with non-type 1 narcolepsy who underwent overnight video-polysomnography (V-PSG) and MSLT in the Sleep Center, Department of Neurology, Xijing Hospital, Air Force Military Medical University from March 2019 to April 2024 were retrospectively collected. By reducing the number of naps in the MSLT, the diagnostic consistency between the simplified MSLT and the standard 5-nap MSLT was evaluated using the receiver operating characteristic (ROC) curve. The DeLong test was used to compare whether there was a statistically significant difference between the simplified MSLT and the standard 5-nap MSLT. Cohen′s Kappa statistical analysis was performed to compare the diagnostic consistency between the simplified MSLT and the standard 5-nap MSLT.Results:The age of the 216 patients who were ultimately enrolled was 17 (13, 30) years, including 152 male patients (70.4%). The Cohen′s Kappa between the simplified 3-nap MSLT and the standard 5-nap MSLT was 0.875, which was 0.903 between the simplified 4-nap MSLT and the standard 5-nap MSLT (Bonferroni-corrected, both P0.001), indicating high and statistically significant agreement for both simplified protocols with the standard test. However, the DeLong test revealed that the area under the curve of the standard 5-nap MSLT (0.900, 95% CI 0.863-0.938) differed significantly from that of the simplified 3-nap MSLT (0.860, 95% CI 0.817-0.904; P0.05), whereas no significant difference was observed between the standard 5-nap MSLT and the simplified 4-nap MSLT (0.876, 95% CI 0.834-0.918; P0.05). Consequently, performing only the first 4 naps was sufficient for diagnosing narcolepsy type 1. Conclusion:The simplified 4-nap MSLT, specifically the first to fourth naps, may be used for the diagnosis of narcolepsy type 1.

Objective:To investigate the clinical characteristics and risk factors of airway mucus plugging in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:This was a retrospective cross-sectional study. A total of 322 hospitalized AECOPD patients admitted to the First Affiliated Hospital of Anhui Medical University from February 2023 to February 2025 were enrolled. Based on chest high-resolution computed tomography (HRCT) findings of airway mucus plugging, patients were classified into mucus plugging and non-mucus plugging groups. General and clinical data were collected, including age, sex, disease duration, smoking and alcohol history, comorbidities, number of acute exacerbations in the past year, routine blood tests, biochemical indices, pulmonary function, and pathogen detection. The incidence of airway mucus plugging in AECOPD patients was calculated, and differences in baseline characteristics, laboratory parameters, and pulmonary function between the two groups were compared. Logistic regression was used to identify independent risk factors for mucus plugging, and receiver operating characteristic (ROC) curves were plotted to evaluate the predictive value of relevant indicators.Results:Of the 322 enrolled patients, 87(27.02%) were found to have airway mucus plugging. Univariate analysis revealed statistically significant differences between the mucus plug group and the non-plug group in the following parameters (all P<0.05): body mass index (BMI), disease duration, smoking status, Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification, modified British Medical Research Council (mMRC) dyspnea scale, COPD Assessment Test (CAT) score, frequency of acute exacerbations, neutrophil percentage, absolute lymphocyte count, lymphocyte percentage, albumin, C-reactive protein (CRP), activated partial thromboplastin time, fibrinogen, fibrin(ogen) degradation products, D-dimer, Aspergillus infection rate, percentage of forced expiratory volume in 1 second to predicted value (FEV 1%pred), ratio of FEV 1 to forced vital capacity (FEV 1/FVC), and percentage of maximal mid-expiratory flow to predicted value (MMEF 75/25%pred). Multivariate logistic regression analysis identified the following as independent risk factors for airway mucus plugs (all P<0.05): elevated CRP ( OR=1.022, 95% CI: 1.013-1.036), decreased albumin ( OR=0.891, 95% CI: 0.825-0.959), Aspergillus infection ( OR=1.774, 95% CI: 1.366-2.317), and reduced MMEF 75/25%pred value ( OR=0.978, 95% CI: 0.964-0.990). ROC curve analysis showed that the combined predictive model incorporating CRP, albumin, Aspergillus infection, and MMEF 75/25%pred had an area under the ROC curve (AUC) of 0.776(95% CI: 0.714-0.838), which was superior to each individual indicator alone, with AUCs of 0.721 for CRP, 0.687 for albumin, 0.579 for Aspergillus infection, and 0.631 for MMEF 75/25%pred. Conclusions:AECOPD patients with airway mucus plugging exhibit higher inflammatory markers, poorer nutritional status, a higher likelihood of Aspergillus infection, worse pulmonary function, and poorer prognosis. Aspergillus infection, elevated CRP, decreased albumin, and reduced MMEF 75/25%pred are independent risk factors for mucus plugs in AECOPD.
