ObjectiveTo investigate the effects of modified Buyang Huanwu Tang on cerebral ischemia-reperfusion injury (CI/RI) in mice via the PTEN-induced putative kinase 1/E3 ubiquitin ligase (PINK1/Parkin) signaling pathway-mediated mitophagy, and to explore the underlying mechanism by which modified Buyang Huanwu Tang improves CI/RI. MethodsSeventy-two male C57BL/6J mice were randomly divided into six groups (n = 12 per group): Sham-operated group, middle cerebral artery occlusion/reperfusion (MCAO/R) model group, low-, medium-, and high-dose modified Buyang Huanwu Tang groups (8.84, 17.68, 35.36 g·kg-1·d-1), and an aspirin group (13.00 mg·kg-1·d-1). Neurological deficit scores were assessed using the Zea-Longa method. Cerebral infarct volume ratio was measured by 2,3,5-triphenyltetrazolium chloride (TTC) staining. Histopathological changes and neuronal injury in brain tissues were observed using hematoxylin-eosin (HE) staining and Nissl staining. Apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay. Mitochondrial ultrastructure in brain tissue was observed by transmission electron microscopy (TEM). Serum levels of superoxide dismutase (SOD) and malondialdehyde (MDA) were determined by enzyme-linked immunosorbent assay (ELISA). The mRNA and protein expression levels of PINK1, Parkin, microtubule-associated protein 1 light chain 3B (LC3B, LC3Ⅱ/Ⅰ), and p62 in brain tissues were detected by real-time quantitative reverse transcription PCR (Real-time PCR) and Western blot, respectively. ResultsCompared with the sham-operated group, the MCAO/R model group showed significantly increased neurological deficit scores and cerebral infarct volume ratios (P<0.01). Severe cortical injury on the infarct side was observed, characterized by decreased neuronal density, cytoplasmic vacuolation, nuclear pyknosis, a marked reduction in Nissl bodies, dissolution of Nissl bodies in the cytoplasm of some pyramidal neurons, and blurred cellular boundaries. The number of TUNEL-positive cells increased significantly (P<0.01). Mitochondria exhibited cristae membrane rupture and matrix vacuolation, with rupture of the outer mitochondrial membrane and formation of autophagosomes, the number of which increased significantly. Serum SOD activity decreased significantly (P<0.01), while MDA content increased significantly (P<0.01). In infarcted brain tissues of model mice, the relative mRNA expression and protein levels of PINK1, Parkin and LC3B were significantly increased (P<0.05, P<0.01), whereas p62 mRNA and protein expression were significantly decreased (P<0.05, P<0.01), showing statistical significance. Compared with the model group, all treatment groups showed significantly decreased neurological deficit scores and cerebral infarct volume ratios (P<0.01). Neuronal density increased significantly, cytoplasmic vacuolation was alleviated, nuclear morphology tended to be more regular and clearer, Nissl body density increased significantly with reduced dissolution and improved contour clarity. The mitochondrial cristae structure was partially restored, with some mitochondria showing autophagosome encapsulation, and the degree of mitochondrial damage was alleviated. Serum SOD activity increased significantly (P<0.01), while MDA content decreased significantly. The mRNA and protein expression levels of PINK1, Parkin, and LC3Ⅱ/Ⅰ were significantly increased (P<0.05, P<0.01), while p62 mRNA and protein expression in the low- and medium-dose modified Buyang Huanwu Tang groups were significantly decreased (P<0.05, P<0.01), showing statistical significance. ConclusionModified Buyang Huanwu Tang can upregulate the protein expression levels of PINK1, Parkin, and LC3Ⅱ/Ⅰ and downregulate p62 protein expression, suggesting that it may improve CI/RI by regulating the expression of proteins related to the PINK1/Parkin signaling pathway. Regulation of the mitophagy pathway may be one of the mechanisms by which modified Buyang Huanwu Tang alleviates CI/RI in mice.

Fecal microbiota transplantation (FMT) has the potential to rebuild the intestinal microbiome of patients, which can influence the disease course, alleviate symptoms, or even cure the disease. It is seen as a promising breakthrough for treating major chronic diseases that are difficult to manage. Currently, FMT therapy has been clinically studied for over 80 diseases and has led to significant breakthroughs. However, there are still four main challenges: (1) identifying the effective characteristics of donor microbiota and ensuring precise matching between donors and recipients; (2) understanding the pathways and molecular mechanisms by which key FMT bacteria and metabolites improve disease outcomes; (3) studying strain interactions and colonization mechanisms to restore intestinal microbiota balance; and (4) refining the precision of microbiome and functional microbiota transplantation. To address these clinical challenges, this article reviews the latest research both domestically and internationally, outlines the response patterns of FMT therapy, examines the reasons behind FMT failure, and explores future directions for the development of FMT. The aim is to accelerate the scientific and precise advancement of FMT technology in China.

Evidence-based public health, as the forefront of modern public health practice, has increasingly important in public health field. However, a significant gap remains between the available evidence and its practical application. Effectively disseminating and implementing evidence-based public health practice in real-world settings has become a key challenge in contemporary public health research. In this context, Implementation Science has emerged as a vital discipline. This paper explores the critical role of Implementation Science in public health, reviews the origins and core components of the Consolidated Framework for Implementation Research (CFIR), and analyzes the current application of CFIR in public health through bibliometric methods. Additionally, it discusses specific examples to further elucidate the steps involved in using the CFIR and its application contexts. The findings indicate that since 2015, research on CFIR in public health has progressively increased, showing a continuous upward trend. CFIR applications mainly address context-specific facilitators, health decision-making, barrier and facilitator identification, and community-based participatory evaluation, predominantly employing qualitative and mixed-methods research. This paper not only reviews and analyzes the current use of CFIR in public health but also provides a detailed discussion on its application. The goal is to offer valuable insights for the development of Implementation Science research within China's public health sector.

Background Hypertension is one of the chronic diseases with the highest prevalence in China, and a history of hypertension may potentially exacerbate hearing loss. Investigating the association between long-term blood pressure trends and hearing thresholds could contribute to hearing protection efforts for occupationally noise-exposed populations. Objective By investigating hearing thresholds and blood pressure levels among occupationally noise-exposed workers in an urban rail transit enterprise, and conducting a comprehensive analysis of the association between long-term blood pressure changes and hearing thresholds, to provide data references for health management strategies targeting occupationally noise-exposed workers. Methods Workers exposed to occupational noise at a rail transit enterprise were enrolled as study subjects and underwent pure-tone audiometry. Group-based trajectory modeling was employed to identify blood pressure trajectories. Categorical data were compared using chi-square tests, while normally distributed continuous variables were analyzed via t-tests and analysis of variance (ANOVA). Generalized linear mixed models (GLMMs) were subsequently applied toexamine associations between these trajectory groups and high-frequency hearing thresholds. Results Among 2 002 occupationally noise-exposed workers, the median (P25, P75) age was 32 (28, 35) years, with a median (P25, P75) working tenure of 7 (3, 10) years. In 2019, the positive hypertension rate was 9.04%, with a mean systolic blood pressure (SBP) of (122.97±11.60) mmHg and a mean diastolic blood pressure (DBP) of (76.37±9.02) mmHg. The hearing loss prevalence was 10.1%, showing bilateral high-frequency average hearing thresholds of (17.18±8.71) dB and speech-frequency average thresholds of (13.79±3.46) dB. Three distinct trajectory groups were identified for both SBP and DBP. Compared with other trajectory groups, the high-stable DBP group exhibited significantly higher hearing loss prevalence (χ2=6.34, P=0.042) and elevated high-frequency hearing thresholds (all Ps<0.05). Specifically, within the 30-39 age subgroup, the moderate-stable DBP group demonstrated 1.96 dB lower high-frequency thresholds than the high-stable group [β(95%CI): −1.96 (−3.61, −0.32), P=0.020]. Conclusion Among occupationally noise-exposed workers in a municipal rail transit enterprise, DBP trajectories demonstrated a positive association with high-frequency hearing thresholds. Notably, in young and middle-aged occupationally noise-exposed populations, DBP may exert a more critical influence than SBP on the progression of hearing loss.
