Objective: To explore the association between daytime outdoor physical activity (OPA) and oral health indicators among primary school students, aiming to provide evidence for developing oral health intervention strategies based on natural exposure. Methods: In October 2023, based on the "Tianchang Children s Light Exposure and Growth Development Cohort", 799 second and third grades children were recruited from two primary schools in Tianchang, Chuzhou City, Anhui Province. Physical activity intensity and light exposure were objectively monitored for 24 hours over 5 consecutive days using triaxial accelerometers synchronized with portable illuminance meters. Standardized oral examinations were performed to record dental caries, gingivitis, and malocclusion. Demographics, lifestyle variables, and household socioeconomic data were collected via questionnaires. Multiple linear regression (for the number of carious teeth) and Logistic regression (for gingivitis risk) were used to analyze the relationship between daytime outdoor moderate to vigorous physical activity (MVPA) and oral health outcomes. Results: The average daytime outdoor MVPA was (0.76±0.35)h, with (0.95±0.40)h on weekdays and (0.49±0.47)h on weekends. The detection rates for dental caries, gingivitis, and malocclusion were 31.0%, 4.6%, and 59.7%, respectively. Compared with children with good oral health, the duration of outdoor MVPA on school days was reduced in children with caries or gingivitis ( Z =-11.4, -5.01, both P <0.01). Multiple regression analysis showed that after adjusting for factors such as gender, age, body mass index, oral hygiene behaviors, an increase in daytime outdoor MVPA duration was associated with a decrease in the number of dental caries ( β=-0.64, 95%CI =-0.93 to -0.35) and a reduced risk of gingivitis ( OR= 0.58 , 95%CI =0.34-0.98) in primary school students (both P <0.05). The association was primarily observed on school days ( β=-0.72, 95%CI = -1.07 to -0.37; OR=0.42, 95%CI =0.21-0.85) (both P < 0.05). Conclusions Daytime outdoor MVPA on weekdays is significantly associated with a lower number of carious teeth and a reduced risk of gingivitis in primary school students. Increasing daytime outdoor activities on weekdays may serve as a promising and potential strategy for promoting children s oral health.

Clonorchis sinensis primarily lives in the host liver and biliary system, leading to serious health issues, such as hepatobiliary lesions and cholangiocarcinoma.

Recently, molecular biological techniques have been widely used for detection of C. sinensis infections. This review summarizes the advances in the major molecular assays for detection of C. sinensis infections in intermediate and definite hosts, including PCR, loop-mediated isothermal amplification, clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated proteins system, and high-throughput sequencing, and summarizes the characteristics and application prospects of these assays, so as to provide precision detection and management of C. sinensis infection.

OBJECTIVE To construct a pharmacy service quality evaluation system， identify weaknesses in the integrated development of pharmacy services， and provide a reference for the homogenized and high-quality development of pharmacy services in compact urban medical groups.METHODS Guided by the five core dimensions of the Servperf model， the Delphi method was used to screen and optimize items， and a tripartite pharmacy service quality evaluation system， covering clinicians， pharmacists， and patients， adapted to the characteristics of compact urban medical groups was constructed. A multicenter cross-sectional empirical investigation was conducted in six compact urban medical groups in Chongqing using the evaluation system.RESULTS Through two rounds of Delphi consultation with 12 experts， a tripartite pharmacy service quality evaluation system was successfully constructed， comprising 5 dimensions and 78 items （24 for clinical pharmacists， 23 for clinical medical staff， and 31 for patients and family members）. The Cronbach’s α coefficients for all dimensions exceeded 0.81， and the KMO values all exceeded 0.7. A total of 1 339 valid questionnaires were collected， including 279 from clinical pharmacists， 727 from clinical medical staff， and 333 from patients and family members. The empirical investigation showed that the overall quality of regional basic pharmacy services was good， but significant inter-group differences existed in service perceptions among the three groups. The score differences across the five dimensions were all statistically significant among the three groups （all P ＜0.001）. Except for the tangibles dimension， in which clinical medical staff scored significantly lower than clinical pharmacists and patients/family members， patients/family members scored significantly higher than clinical medical staff and clinical pharmacists in the other four dimensions （ P ＜0.05）. For the 78 items， expert expectations largely matched the perceptions of the three groups， with a mean difference of 0.08 points； only 13 items showed a difference exceeding 0.5 points， representing marked gap，with “participating in multidisciplinary team consultation and making effective recommendations” showing the largest difference of 0.94 points.CONCLUSIONS The physician‑ pharmacist‑patient tripartite evaluation system constructed in this study is scientific and reliable. Empirical investigation confirms that the basic pharmaceutical support services of the medical groups are well established， whereas the development of high‑level collaborative services has notable weaknesses， and marked heterogeneity exists in service perception among the three groups.

Background: The genus Atractylodes, native to East Asia, encompasses several species that serve as sources for the widely used traditional Chinese medicines Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma. However, the international trade arouses concern regarding potential confusion and misidentification of Atractylodes species. Objective: A comprehensive understanding of the chemical diversity is crucial for ensuring the quality and exploring the potential variations in medicinal efficacy of Atractylodes. Methods: The GC-MS/MS-based metabolomics and multivariate statistical analysis identified 589 differentially accumulated metabolites across 5 Atractylodes species. Results: A total of 150 metabolites were predicted as potential chemical markers for species differentiation and quality assessment of Atractylodes. According to the metabolic profiles, the species of Atractylodes can be roughly classified into three categories: A. lancea and A. coreana with the volatile oil components being mainly atractylodin and β-eudesmol; A. macrocephala with the biomarker being atractylon; and A. japonica and A. carlinoides lying between the two categories above. Conclusions: Metabolomic results indicated that the metabolic profiles of A. carlinoides and A. macrocephala were similar and distinct from those of the other three species. Sesquiterpenoids were the main chemical components in the rhizome of A. carlinoides, which indicated the potential medicinal value of this plant.

Chronic epididymitis (CE) is a long-standing inflammatory condition of the epididymis caused by unresolved acute infections, chronic infections, medication use, or other factors. Clinically, it is characterized by persistent dull pain or a dragging sensation in one or both sides of the scrotum. The disease course typically exceeds three months and is marked by insidious onset and recurrent episodes. Current studies suggest that CE may disrupt the epididymal microenvironment through multiple pathological processes, including local inflammatory responses, oxidative stress, fibrotic remodeling, and autophagy. These alterations impair sperm maturation, transport, and capacitation, thereby contributing to male reproductive dysfunction and infertility. This review summarizes the major etiologies and pathophysiological characteristics of CE and its impact on male reproductive function. It focuses on the roles of inflammatory cytokines and related signaling pathways, oxidative stress mechanisms, and fibrotic progression in the pathogenesis of CE. Moreover, it explores targeted therapeutic strategies based on these mechanisms, aiming to provide a theoretical basis for identifying key molecular targets and signaling pathways involved in CE-induced male reproductive impairment.
