Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by the selective loss of dopaminergic neurons in the substantia nigra pars compacta and the pathological accumulation ofα‑synuclein. Although extensive progress has been made in elucidating its pathogenesis, current therapeutic approaches remain largely symptomatic, and effective disease-modifying treatments are still unavailable. Increasing evidence indicates that PD is driven by the interaction of multiple pathological processes, including neuroinflammation, iron homeostasis dysregulation and ferroptosis, endoplasmic reticulum (ER) stress, mitochondrial dysfunction, oxidative stress, and impaired protein homeostasis, which together contribute to neuronal vulnerability and degeneration. Fibroblast growth factors (FGFs) comprise a family of 22 ligands that play important roles in neural development, stress responses, metabolic regulation, and the maintenance of nervous system homeostasis. Recent studies have shown that several FGF family members, such as FGF1, FGF2, FGF9, and FGF21, exert neuroprotective effects in cellular and animal models of PD. These effects include the regulation of inflammatory responses, oxidative stress, iron homeostasis, cellular stress adaptation, and neuronal survival. Compared with therapeutic strategies targeting a single pathogenic pathway, FGFs appear to influence multiple disease-related processes, suggesting their potential relevance to the complex pathophysiology of PD. Experimental evidence indicates that altered FGF signaling may contribute to dopaminergic neuron dysfunction through the coordinated regulation of several interconnected mechanisms. FGFs have been reported to modulate neuroinflammation by affecting the activation of microglia and astrocytes, thereby influencing the inflammatory environment in the central nervous system. In addition, FGFs are involved in the regulation of iron homeostasis and ferroptosis, partly through antioxidant signaling pathways associated with NRF2, SLC7A11, and GPX4. Moreover, FGFs can alleviate ER stress and mitochondrial dysfunction by activating intracellular signaling pathways such as PI3K/AKT, AMPK-PGC-1α, as well as SIRT1-dependent programs, which support cellular energy metabolism and redox balance. Recent advances in single-cell and spatial transcriptomic studies further suggest that FGF signaling is not limited to neuron-intrinsic mechanisms but also involves interactions among different glial cell types. Altered FGF ligand-receptor communication between astrocytes and oligodendrocytes has been observed in PD models and is associated with increased susceptibility of dopaminergic neurons to oxidative stress and ferroptosis. These findings indicate that the biological effects of FGFs are influenced by cell type and disease stage and may vary under different pathological conditions. In this review, we summarize recent progress in understanding the roles of FGF family members in PD, with a focus on their involvement in iron homeostasis dysregulation and ferroptosis, neuroinflammation, cellular stress responses, and neuronal protection and regeneration. By integrating current evidence, this review aims to provide a clearer understanding of how FGFs participate in PD pathogenesis and to offer a theoretical basis for future studies exploring their potential value in disease-modifying therapeutic strategies.

ObjectiveTo evaluate the effectiveness of exhalation-inhalation exercise on early pulmonary rehabi-litation for patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). MethodsA total of 120 participants with AECOPD were randomly divided into a treatment group and a control group, with 60 participants in each group. The control group treated with conventional western medicine, while the treatment group received exhalation-inhalation exercise training on the basis of conventional western medicine treatment, with 30 minutes per session and 5 sessions per week. The course of treatment for both groups was 12 weeks. The primary outcome was the 6-minute walking distance (6MWD). The secondary outcomes included pulmonary function indexes including forced expiratory volume in one second/forced vital capacity (FEV1/FVC), percentage of predicted forced expiratory volume in one second (FEV1%) and percentage of predicted forced vital capacity (FVC%), St.George's Respiratory Questionnaire (SGRQ) score, modified Medical Research Council (mMRC) dyspnea scale score, COPD assessment test (CAT) score, hospital anxiety and depression scale-anxiety subscale [HADS(A)] score, and hospital anxiety and depression scale-depression subscale [HADS(D)] score. Meanwhile, safety of all participants was recorded and assessed. ResultsDuring the treatment, 12 participants dropped out from both the treatment group and the control group, with 48 participants in each group finally included in the analysis. The 6MWD of both groups after treatment was higher than that before treatment, and the 6MWD of the treatment group was higher than that of the control group (P<0.05 or P<0.01). After treatment, the SGRQ score, mMRC score and CAT score of the treatment group were lower than those before treatment, while FEV1%, FVC% and FEV1/FVC were higher than those before treatment (P<0.05). Moreover, after treatment, the FEV1/FVC of the treatment group was higher than that of the control group, while the SGRQ score, mMRC score and CAT score were lower than those of the control group (P<0.05 or P<0.01). There was no statistically significant difference in pulmonary function indexes, SGRQ score, mMRC score and CAT score after treatment in the control group (P>0.05). No statistically significant difference was observed in HADS(A) score and HADS(D) score after treatment within and between groups (P>0.05). The incidence of adverse reactions in the treatment group was 6.25% (3/48), and 0 in the control group, with no statistically significant difference between groups (P>0.05). ConclusionExhalation-inhalation exercise for patients with AECOPD in early pulmonary rehabilitation can improve patients' exercise tole-rance, quality of life, clinical symptoms and pulmonary function, with good safety.

Background The quality of occupational health technical services is directly linked to the protection of workers' health rights and the efficacy of occupational disease prevention and control. However, the industry still faces critical challenges: sporadic instances of institutional non-compliance and persistent irregularities in professional practice continue to undermine overall service performance. Objective To assess the current quality status of occupational health technical services in Zhejiang Province and propose countermeasures for quality improvement, providing a scientific basis for policy optimization and service delivery quality enhancement. Methods A total of 69 occupational health technical service institutions in Zhejiang Province that obtained formal accreditation as of April 30, 2024, were sampled, including 3 public institutions and 66 private institutions (comprising 3 formerly Class-A, 28 formerly Class-B, 11 formerly Class-C, and 24 newly certified institutions). Following the Technical Protocol for Quality Monitoring of Occupational Health Technical Service in Zhejiang Province and the Technical Protocol for Proficiency Testing of Occupational Health Detection in Zhejiang Province, a quality assessment task force comprising national and provincial experts was established. Evaluation was conducted across four dimensions: qualification maintenance and compliance, standardization of technical services, authenticity of technical services, and proficiency testing, utilizing a combination of document review, on-site inspections, and technical skill assessments. Results The occupational health technical service institutions in Zhejiang Province were predominantly private entities (82.5%), with significant disparities in overall service quality. The pass rates for qualification maintenance and compliance, technical service standardization, technical service authenticity, and the excellence rate for laboratory proficiency testing were 81.5%, 80.7%, 97.3%, and 90.4%, respectively. Regarding qualification maintenance, the pass rates for "environmental conditions" (49.8%, 56.7%) and "instrumentation and equipment" (58.2%、65.6%) were significantly lower for formerly Class-C and newly certified institutions compared to other categories. In terms of technical standardization, "standardized on-site inspections" recorded the lowest pass rate (67.4%), with newly certified institutions at only 48.0%. Regarding technical service authenticity, formerly Class-C institutions exhibited issues such as missing raw chromatograms for blank samples (85.7% pass rate). In laboratory proficiency testing, public and formerly Class-A institutions achieved 100% excellence rates, but the performance of formerly Class-C and newly certified institutions was comparatively weak; specifically, the failure rate for organic analysis in formerly Class-C institutions reached 20%; the failure rate for dust testing items in newly certified institutions was 10.3%. Conclusion The overall quality of occupational health technical services in Zhejiang Province still requires significant improvement, particularly in basic institutional conditions, the standardization of on-site inspections, and laboratory proficiency in organic and dust analysis. Formerly Class-C and newly certified institutions should be the primary focus of quality management efforts. Differentiated regulatory strategies are recommended, alongside strengthening interim and ex-post supervision to gradually enhance the quality of occupational health technical services across all institutions.

The Chinese health index assessment system integrates the dialectical thinking of traditional philosophy, taking the Taoist cosmology, Confucian ethical view, and the holistic perspective of traditional Chinese medicine (TCM) as its theoretical foundation. It deeply analyzes the sages' conceptions of the ideal personality and social order, as well as their ideas on mind-body cultivation, while incorporating modern health concepts from psychology, medicine. The study systematically explicates the connotation and characteristics of eight components of the Chinese health index, including harmony, dedication, compassion, happiness, peace of mind, innovation, fulfillment, and adaptability. This system establishes a multidimensional assessment framework covering physical health, psychological well-being, human-social relations, and the relationship with nature, which demonstrates high cultural adaptability and practical applicability, offering theoretical reference for assessing the mind-body health of the Chinese population and for informing health promotion policies.

ObjectiveTo explore the clinical and phenomics characteristics of patients with phlegm-stasis binding syndrome and its accompanied patterns in stable angina pectoris (SAP) of coronary heart disease (CHD). MethodsA multicenter cross-sectional study design was adopted. A total of 300 patients with SAP of CHD were enrolled and classified into 120 cases of phlegm-stasis binding syndrome, 125 cases of qi deficiency-accompanied syndrome, 38 cases of qi stagnation-accompanied syndrome, and 17 cases of toxin accumulation-accompanied syndrome according to traditional Chinese medicine (TCM) patterns. Data of patients with different TCM patterns were collected, including general condition, TCM symptoms, blood lipids, coagulation function, immune indicators, and serum metabolomics. Metabolic pathway enrichment analysis was used to compare differences in phenomics characteristics among groups. Metabolites with variable importance in projection (VIP) ≥1 and fold change (FC) ≥2 were considered as representative differential metabolites. ResultsPatients in each TCM pattern type were most commonly in the 60-75 years age group, with a relatively high proportion of males. Regarding TCM symptoms, patients with phlegm-stasis binding syndrome most commonly presented with wiry-choppy or wiry-slippery pulse, chest pain, and chest tightness; in patients with qi deficiency-accompanied syndrome, fatigue, chest pain, and weak pulse were most common; in patients with qi stagnation-accompanied sydnrome, wiry-choppy or wiry-slippery pulse, chest pain, and symptoms that increase or decrease with emotional changes, belching, or flatulence were most common; in patients with toxin accumulation-accompanied syndrome, bitter taste in the mouth, chest tightness, irritability, restlessness or manic delirium, and dry and hard stools or foul-smelling diarrhea were most common. Comparisons among the different TCM patterns showed statistically significant differences in coagulation parameters (P<0.05), whereas no statistically significant difference was found in blood lipid levels and immune indicators (P>0.05).Metabolomics analysis suggested that disorders of glycerophosphate metabolism and valine, leucine, and isoleucine metabolism are characteristic features of phlegm-stasis binding syndrome and its accompanied patterns. The representative differential metabolites between phlegm-stasis binding syndrome and qi deficiency-accompanied syndrome were 7,8-dihydrobiopterin (FC = 3.58) and oxypurinol (FC = 124.50). Those between phlegm-stasis binding syndrome and qi stagnation-accompanied syndrome were cytidine 5′-diphosphocholine (FC = 2.62) and D-mannosamine (FC = 2.99). Those between phlegm-stasis binding syndrome and toxin accumulation-accompanied syndrome were anserine (FC = 7.83) and canrenone (FC = 8.94). ConclusionThere are certain differences in the clinical characteristics and phenomics characteristics among patients with SAP due to CHD exhibiting phlegm-stasis binding syndrome and its accompanied patterns. The phenomics characteristics mainly involve biological alterations such as lipid metabolism disorders, amino acid metabolism abnormalities, and multiple immune indicators activation, which may provide a reference for precise differentiation and treatment of SAP of CHD in TCM clinical practice.

Lung cancer constitutes the most prevalent and lethal malignant tumor in China. Approximately 85% of lung cancer diagnoses correspond to the non-small cell histological subtype [non-small cell lung cancer (NSCLC)]. Despite surgery being the mainstay for early-stage disease, postoperative recurrence remains high and adjuvant chemotherapy offers limited benefit. In recent years, targeted therapy has demonstrated substantial advantages in driver mutation-positive NSCLC. To this end, the Lung Cancer Medical Education Committee of the Chinese Medical Education Association developed guidelines based on a systematic review of evidence through November 2025, using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach and a modified Delphi method. Focusing on epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), and addressing ROS proto-oncogene 1 (ROS1), B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation, and mesenchymal-epithelial transition factor (MET) exon 14 (METex14) skipping, the guideline covers molecular testing, neoadjuvant/adjuvant therapy, perioperative strategies, minimal residual disease monitoring, and postoperative surveillance. It defines testing requirements, specifies stage-directed and subtype-specific treatments, and standardizes minimal residual disease monitoring. These recommendations emphasize precision and feasibility to improve survival and quality of life.

Objective To analyze the global pattern, long-term trends, and regional and population heterogeneity in the burden of 375 diseases and injuries and 88 risk factors from 1990 to 2023 using data from the Global Burden of Disease Study 2023 (GBD 2023). Methods Publicly available GBD 2023 estimates were extracted for incidence, deaths, years of life lost (YLLs), years lived with disability (YLDs), disability-adjusted life years (DALYs), and age-standardized rates at the global level and by socio-demographic index (SDI), GBD region, age group, and sex. Descriptive analysis, ranking comparison, stratified analysis, and trend analysis were performed, and 95% uncertainty interval was used to assess the stability of estimates. Results In 2023, non-communicable diseases were the leading contributor to global DALYs, accounting for 64.39% of DALYs across the three major disease and injury groups (communicable, maternal, neonatal, and nutritional diseases, non-communicable diseases, and injuries), and also had the highest age-standardized DALYs rate. From 1990 to 2023, age-standardized DALYs rates declined for three major disease and injury groups, with estimated annual percentage changes of −2.69%, −0.78%, and −1.47%, respectively. Cardiovascular diseases ranked first by both DALYs and deaths in 2023, whereas respiratory infections and tuberculosis ranked first by incidence. Non-communicable diseases were the leading cause of disease burden across all SDI strata. As the SDI level declined, the burden of communicable, maternal, neonatal, and nutritional diseases, as well as injuries, increased markedly. Behavioral and metabolic risks remained the main contributors to attributable deaths and DALYs. Conclusion From 1990 to 2023, the global burden of disease continues to shift toward non-communicable diseases; however, some regions still face a double burden of infectious, maternal and child, injury-related, and chronic diseases. Integrating deaths, DALYs, YLLs, YLDs, and risk-attributable burden helps identify priority areas for prevention and resource allocation across regions and populations.

ObjectiveTo explore the potential mechanism of acupuncture with the method of soothing the liver and regulating the mind in improving depressive disorder. MethodsEighteen C57BL/6J mice were randomly divided into blank group, model group, and acupuncture group, with 6 mice in each group. The model group and the acupuncture group were subjected to depression induction by intraperitoneal injection of lipopolysaccharide (LPS), while the blank group received an equal volume of normal saline once daily for seven consecutive days. Concurrently, the acupuncture group received "soothing the liver and regulating the mind" acupuncture intervention starting from the first day of modeling, once daily for 14 days; whereas the blank group and the model group were only restrained without acupuncture. The sucrose preference test was used to assess sucrose preference rate, the open-field test to measure center stay time and total travel distance, and the forced swim test to evaluate immobility time. Hematoxylin-eosin (HE) staining was performed to observe hippocampal morphological changes. Enzyme-linked immunosorbent assay (ELISA) was used to detect levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in hippocampal tissue. Western blot analysis was conducted to examine the protein expression levels of Toll-like receptor 4 (TLR4) and nuclear factor-κB (NF-κB) in the hippocampus. ResultsCompared to the blank group, the model group showed a significant reduction in sucrose preference rate, center stay time, and total travel distance, along with a significant increase in immobility time in the forced swim test, hippocampal IL-1β, IL-6, and TNF-α levels, as well as TLR4 and NF-κB protein expression (P<0.01), and the histological examination revealed blurred hippocampal neuronal boundaries, loose arrangement, and some neurons exhibiting nuclear pyknosis and deep staining. Compared to the model group, the acupuncture group demonstrated a significant increase in sucrose preference rate, center stay time, and total travel distance, along with a significant reduction in immobility time in the forced swim test, hippocampal IL-1β, IL-6, and TNF-α levels, and TLR4 and NF-κB protein expression (P<0.01), and the histological analysis showed that hippocampal neurons in the acupuncture group were more tightly arranged, with reduced nuclear pyknosis and deep staining. ConclusionAcupuncture with the "soothing the liver and regulating the mind" method can significantly improve depression-like behavior, potentially by inhibiting the hippocampal TLR4/NF-κB signaling pathway and alleviating inflammatory responses.

ObjectiveTo investigate whether the effect of Taohong Siwutang on cerebral ischemia-reperfusion (CIRI) injury in rats is related to the regulation of astrocyte polarization and explore the related mechanism. MethodsEighty-four male SD rats were randomly assigned to the following groups: A sham operation group, a model group, Taohong Siwutang treatment groups (low dose, medium dose, and high dose), ligustrazine phosphate tablet (LPT) group, and AG490 group. All groups, except for the sham operation group, underwent middle cerebral artery occlusion/reperfusion (MCAO/R) modeling and were treated for seven days. The neurological impairment was evaluated using the Longa score. The volume of cerebral infarction was assessed through 2,3,5-triphenyltetrazolium chloride (TTC) staining. Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) and Western blot analyses were performed to analyze the mRNA and protein expression levels of cortical complement 3 (C3), S100 calcium-binding protein A10 (S100A10), Janus kinase 2 (JAK2), and signal transducer and activator of transcription 3 (STAT3). Additionally, protein expression levels of vascular endothelial growth factor-A (VEGF-A) were assessed, and the mRNA expression levels of inflammatory factors, including interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α), were evaluated. Glial fibrillary acidic protein (GFAP) and C3, S100A10 and Co-localization was detected via immunofluorescence double staining. Lastly, VEGF expression levels were measured using enzyme-linked immunosorbent assay (ELISA). ResultsCompared with the sham operation group, the model group showed a significant increase in cerebral infarction volume and neurological impairment (P<0.01). C3 protein levels were elevated, while S100A10 levels were decreased. Pathway-related markers were significantly upregulated (P<0.05, P<0.01), and VEGF-A protein levels were significantly reduced (P<0.01). The mRNA expression of inflammatory factors was significantly upregulated (P<0.01). Co-localization analysis showed significantly increased GFAP and C3 fluorescence intensity (P<0.01) and greatly decreased GFAP and S100A10 fluorescence intensity (P<0.01). Additionally, VEGF content was significantly elevated (P<0.01). Compared with the model group, medium- and high-dose Taohong Siwutang and LPT groups exhibited a significant reduction in cerebral infarction volume and neurological impairment (P<0.01). Groups treated with low, medium, and high doses of Taohong Siwutang and LPT group exhibited a decrease in C3 protein expression levels and an increase in S100A10 expression levels (P<0.01). In the high-dose Taohong Siwutang and AG490 groups, both protein and mRNA expression of C3 and pathway-related markers were significantly downregulated (P<0.05, P<0.01), while S100A10 expression and VEGF-A protein levels were significantly increased (P<0.01). Additionally, the mRNA expression levels of inflammatory factors were significantly reduced (P<0.01). The co-localization fluorescence intensity of GFAP and C3 significantly decreased (P<0.01), while that of GFAP and S100A10 greatly increased (P<0.01). Furthermore, VEGF content exhibited a marked elevation (P<0.01). ConclusionTaohong Siwutang exerts a protective effect in rats with cerebral CIRI injury. The underlying mechanism is associated with the downregulation of the JAK2/STAT3 signaling pathway, promotion of A2-type astrocyte polarization, reduction of inflammatory factor release, and enhancement of VEGF production.
