Age-related macular degeneration(ARMD)is a progressive visual impairment fundus disease that frequently occurs in individuals aged >55 years. The main risk factors are aging, long-term smoking, genetics, and racial differences. Pathogenesis includes abnormal function of the retinal pigment epithelium, damaged blood-retinal barrier, and abnormal immune function. Currently, intravitreal injection(IVI)of anti-vascular endothelial growth factor(VEGF)drugs is the preferred treatment option for ARMD in clinical practice. However, it also faces challenges such as repeated treatments, high medical costs, and poor patient compliance. The predicament in the treatment of ARMD has given rise to several new treatment options. This article aims to review the treatment methods and progress of dry ARMD and wet ARMD, providing new ideas for addressing the limitations of the current clinical anti-VEGF treatment.

ObjectiveTo compare the differences between wild Alpiniae Oxyphyllae Fructus(WAOF) and cultivated Alpiniae Oxyphyllae Fructus(CAOF) through a traditional quality evaluation system for medicinal materials. MethodsA total of 10 batches of WAOF and 12 batches of CAOF samples were collected from various regions of Hainan province. Relevant analytical methods from the 2020 edition of the Pharmacopoeia of the People's Republic of China were employed to observe the characteristics of WAOF and CAOF, followed by microscopic identification, thin-layer chromatography(TLC) identification, moisture content(toluene method), total ash, acid-insoluble ash, water-soluble and alcohol-soluble extracts(hot dipping method), water-soluble protein, total polysaccharides and total flavonoids(ultraviolet spectrophotometry), and volatile oil content(method A under general rule 2204). The contents of five active components(protocatechuic acid, chrysin, kaempferol, tectochrysin and nootkatone) were quantified using ultra-performance liquid chromatography(UPLC), and the antioxidant activity was evaluated. Building upon traditional quality evaluation of AOF, quantitative measurements were conducted on its appearance traits including diameter, length, plumpness(diameter/length ratio), and color. Canonical correlation analysis was performed using SPSS 26.0 to explore relationships between appearance traits and intrinsic quality. ResultsNo significant differences were observed between WAOF and CAOF in microscopic observation, TLC identification, moisture content, protocatechuic acid content, kaempferol content, odor, or antioxidant activity measured by 2,2ʹ-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS) method. WAOF exhibited significantly higher levels in water-soluble extracts, alcohol-soluble extracts, total polysaccharide content, water-soluble protein content, 100-grain weight, length, and total color difference(ΔE*ab) compared to CAOF(P<0.01). In contrast, CAOF showed significantly higher levels of total ash, acid-insoluble ash, content of total flavonoids, volatile oil content, chrysin content, tectochrysin content, nootkatone content, diameter, plumpness, lightness(L*), red-green chromaticity(a*), yellow-blue chromaticity(b*), and antioxidant activity measured by 1,1-diphenyl-2-picrylhydrazyl(DPPH) method compared to WAOF(P<0.01). Correlation analysis between 7 phenotypic traits and 8 quality traits revealed that among the phenotypic traits, plumpness, L*, a*, and b* exerted significant influence on intrinsic quality. Among the quality traits, total flavonoids, volatile oils, nootkatone, chrysin, and tectochrysin contributed substantially to intrinsic quality. ConclusionPlumpness, L*, a*, and b* of AOF significantly influence its intrinsic quality, and higher values of these parameters indicate relatively superior intrinsic quality. The comprehensive quality evaluation reveals that CAOF samples collected in this study are superior to their wild counterparts.

ObjectiveTo analyze the current status and existing challenges in talent cultivation for sports rehabilitation in China based on World Health Organization rehabilitation competency framework (RCF). MethodsData were collected from 104 higher education institutions nationwide that offer undergraduate programs in sports rehabilitation, including enrollment scale, regional distribution, degree conferral and training curriculum. Descriptive statistics and content analysis were used to examine the status and characteristics from three dimensions: institutional distribution, competency development and resource allocation, in terms of institutional type, regional distribution density, curriculum structure differences, competency-oriented training approaches and resource allocation patterns. ResultsTalent cultivation in sports rehabilitation in China currently faced a three-dimensional dilemma involving competency, resources, and public cognition. In terms of competency structure, a disconnect existed between medical fundamentals and exercise practice: physical education institutions provided insufficient medical training, whereas medical institutions lacked systematic instruction in exercise techniques. Regarding resource allocation, significant regional disparities were observed, with institutions heavily concentrated in Southwest (24.0%), East China (19.2%), and North China (15.4%), while Northwest China accounted for only 3.8%, forming a pronounced east-west gap. At the cognitive level, the public generally perceived sports rehabilitation as a service exclusive to athletes, and within the discipline, divergences persisted among the medical-oriented, sports-oriented, and integrated schools of thought. These challenges collectively hindered the quality of talent supply and regional balance. ConclusionTalent cultivation in sports rehabilitation in China is at a pivotal stage of transition from rapid expansion to quality enhancement. It is necessary to realign the knowledge structure and competency system of training programs with the five core competency domains of RCF.

Abstract
To promote adolescents active participation in physical activity and improve sleep quality, the article analyzes the relationship of adolescent physical activity with subjective sleep satisfaction, sleep latency, sleep continuity, sleep efficiency, and sleep duration. It explores potential mechanisms underlying the link between physical activity and sleep quality, including physiological mechanisms (circadian rhythms, body temperature, neuroendocrine systems, and immune function), and psychological mechanisms (stress relief, improvement of negative emotions, and promotion of mental relaxation). Based on existing research, it is recommended that adolescents engage in moderate to vigorous physical activity daily to promote improved sleep quality.

ObjectiveTo investigate the protective effect of Xielitang on dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) mice and its possible mechanism. MethodsDSS was used to establish UC model. Sixty mice were randomly divided into a normal group, a model group, a sulfasalazine group (0.6 g·kg-1), and low-, medium-, and high-dose Xielitang groups (1.67, 3.34, 6.68 g·kg-1). After treatment for 42 d, the colon length was recorded, and the disease activity index (DAI) score was calculated. Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-10 (IL-10). Hematoxylin-eosin (HE) staining was used to observe the pathomorphological changes of colon. Western blot was used to detect the protein expression of farnesoid X receptor (FXR), small heterodimer partner (SHP), liver receptor homolog-1 (LRH-1), cholesterol 7α-hydroxylase (CYP7A1), and fibroblast growth factor receptor 4 (FGFR4) in liver and FXR, sodium-dependent bile acid transporter (ASBT), and fibroblast growth factor 15 (FGF15) in ileum. 16S rRNA sequencing was used to analyze the intestinal flora. Moreover, ultra-high performance liquid chromatography–tandem mass spectrometry was used to detect the bile acid content. ResultsCompared with the normal group, the model group showed significantly decreased colon length, IL-10 content, α-diversity index, abundance of Firmicutes and Lactobacillus, and content of deoxycholic acid (DCA) and lithocholic acid (LCA) (P<0.01), significantly increased DAI score, IL-6 and TNF-α content, abundance of Bacteroidetes, and the content of cholic acid (CA), chenodeoxycholic acid (CDCA), and taurocholic acid (TCA) (P<0.05, P<0.01), significantly down-regulated protein expression of FXR, SHP, and FGFR4 in liver and FXR, ASBT, and FGF15 in ileum (P<0.01), and significantly up-regulated protein expression of LRH-1 and CYP7A1 in liver (P<0.01). In addition, the structure of colonic mucosa was destroyed, and inflammatory cells infiltrated in the model group. Compared with the model group, Xielitang could significantly increase the colon length, IL-10 content, α-diversity index, the abundance of Firmicutes and Lactobacillus, and DCA and LCA content (P<0.05, P<0.01), decrease DAI score, abundance of Bacteroidetes, and the content of IL-6, TNF-α, CA, CDCA, and TCA (P<0.01), up-regulate the protein expression of FXR, SHP, and FGFR4 in liver and FXR, ASBT, and FGF15 in ileum (P<0.01), and down-regulate the protein expression of LRH-1 and CYP7A1 in liver (P<0.01). The pathological damage of colonic mucosa was obviously alleviated. ConclusionXielitang protects against UC probably by regulating the "intestinal microbiota-bile acid" axis, regulating intestinal flora imbalance, and maintaining bile acid homeostasis.

ObjectiveTo reveal the mechanism of Zuogui Jiangtang Jieyu prescription against damage to hippocampal synaptic microenvironment via suppressing glutamate receptor 2 (GluR2)/Parkin signal-mediated mitophagy in rats with diabetes-related depression (DD). MethodsEighty male SD rats underwent adaptive feeding for 5 days before the study. Ten rats were randomly assigned to the normal group. The model of DD rats was established with the rest by 2-week high-fat diet + streptozotocin (STZ) tail intravenous injection + 28 days of chronic unpredictable mild stress (CUMS) combined with isolation. The rats were randomly divided into a normal group, a model group, a GluR2 blocker group (5 μg·kg-1), a GluR2 agonist group (10 μg·kg-1), a metformin + fluoxetine group (0.18 g·kg-1 metformin + 1.8 mg·kg-1 fluoxetine), and high- and low-dose Zuogui Jiangtang Jieyu prescription groups (20.52 and 10.26 g·kg-1, respectively). The rats in the GluR2 blocker group and the GluR2 agonist group were continuously injected with CNQX and Cl-HIBO in the dentate gyrus of the hippocampus once a week starting from stress modeling, respectively, while the metformin + fluoxetine group and the high- and low-dose Zuogui Jiangtang Jieyu prescription groups were continuously given intragastric administration for 28 d at the same time of stress modeling. Depression-like behavior was evaluated by open field and forced swimming experiments. The levels of serum insulin and adenosine triphosphate (ATP) in hippocampus were detected by biochemical analysis. The levels of 5-hydroxytryptamine (5-HT) and dopamine (DA) in hippocampus were detected by enzyme-linked immunosorbent assay (ELISA). The autophagosomes of hippocampal neurons were observed by transmission electron microscopy. The morphology and structure of dendrites and spines of hippocampal neurons were evaluated by Golgi staining. Western blot detected the expression levels of GluR2 and Parkin proteins in hippocampus. The expression levels of GluR2, Parkin, regulating synaptic membrane exocytosis protein 3 (RIMS3), and postsynaptic density protein 95 (PSD95) in the dentate gyrus of the hippocampus were detected by immunofluorescence. ResultsCompared with the normal group, the model group exhibited reduced total activity distance in the open field and increased immobility time in forced swimming (P<0.01), lowered levels of serum insulin and ATP, 5-HT, and DA in hippocampus (P<0.01), increased autophagosomes of hippocampal neurons, significantly damaged morphology and structure of dendrites and spines of hippocampal neurons, decreased expression levels of GluR2, RIMS3, and PSD95 in hippocampus, and an increased Parkin expression level (P<0.05, P<0.01). Compared with the model group, the GluR2 blocker group and the GluR2 agonist group showed aggravation and alleviation of the above abnormal changes, respectively (P<0.05, P<0.01). The above depression-like behavior was significantly improved in the high- and low-dose Zuogui Jiangtang Jieyu prescription groups to different degrees. Specifically, the two groups saw elevated levels of serum insulin and ATP, 5-HT, and DA in hippocampus (P<0.05, P<0.01), restrained increase in autophagosomes and damage to morphology and structure of dendrites and spines of hippocampal neurons, up-regulated protein expression levels of GluR2, RIMS3, and PSD95, and down-regulated Parkin expression level (P<0.05, P<0.01). ConclusionZuogui Jiangtong Jieyu prescription can ameliorate the mitophagy-mediated damage to hippocampal synaptic microenvironment in DD rats, the mechanism of which might be related to the regulation of GluR2/Parkin signaling pathway.

ObjectiveTo study the mechanism of compound Xishu granules (CXG) in inhibiting the proliferation of hepatocellular carcinoma cells by regulating ferroptosis. MethodsThe transplanted tumor model of human Huh7 was established with nude mice and the successfully modeled mice were randomized into model, Fufang Banmao (0.21 g·kg-1), low-dose (1.87 g·kg-1) CXG, medium-dose (3.74 g·kg-1) CXG, and high-dose (7.49 g·kg-1) CXG groups. Mice were administrated with drinking water or CXG for 28 days, and the body weight and tumor volume were measured every 4 days. Hematoxylin-eosin staining was employed to observe the histopathological changes of tumors. The cell-counting kit-8 (CCK-8) was used to examine the survival rate of Huh7 cells treated with different concentrations (0, 31.25, 62.5, 125, 250, 500, 1 000 mg·L-1) of CXG for 24 h and 48 h. CA-AM, DCFH-DA, and C11-BODIPY581/591 fluorescent probes were used to determine the intracellular levels of ferrous ion (Fe2+), reactive oxygen species (ROS), and lipid peroxide (LPO), respectively. The colorimetric method was employed to measure the levels of glutathione (GSH) and superoxide dismutase (SOD). Western blot was employed to determine the protein levels of glutathione peroxidase 4 (GPX4), transferrin receptor 1 (TFR1), and ferritin heavy chain 1 (FTH1), respectively. ResultsIn the animal experiment, compared with the model group, the drug treatment groups showed reductions in the tumor volume from day 12 (P<0.01). After treatment, the Fufang Banmao and low-, medium-, and high-dose CXG groups had lower tumor volume, relative tumor volume, and tumor weight than the model group (P<0.05), with tumor inhibition rates of 48.99%, 79.93%, 91.38%, and 97.36%, respectively. Moreover, the CXG groups had lower tumor volume and relative tumor volume (P<0.05 in all the three dose groups) and lower tumor weight (P<0.05 in medium-dose and high-dose groups) than the Fufang Banmao group. Compared with the model group, the drug treatment groups showed reduced number of tumor cells, necrotic foci with karyopyknosis, nuclear fragmentation, and nucleolysis, and the high-dose CXG group showed an increase in the proportion of interstitial fibroblasts. In the cell experiment, compared with the blank group, CXG reduced the survival rate of Huh7 cells in a dose-dependent manner after incubation for 24 h and 48 h (P<0.05). Compared with the blank group, the RSL3 group and the low-, medium-, and high-dose CXG groups showed a decrease in the relative fluorescence intensity of CA-AM and increases in the fluorescence intensity of DCFH-DA and fluorescence ratio of C11-BODIPY581/591, which indicated elevations in the levels of Fe2+ (P<0.01), ROS (P<0.05), and LPO (P<0.01), respectively. Compared with the blank group, the RSL3 and low-, medium-, and high-dose CXG groups showed lowered levels of GSH and SOD (P<0.05). In addition, the RSL3 group and the medium- and high-dose CXG groups showed down-regulated expression of GPX4 and FTH1 (P<0.05), and the low- and high-dose CXG groups presented up-regulated expression of TFR1 (P<0.05). ConclusionCXG suppresses the proliferation of hepatocellular carcinoma cells by inducing ferroptosis via downregulating the GSH-GPX4 signaling axis and increasing intracellular Fe2+and LPO levels.

ObjectiveTo systematically review the available studies about Guanxinjing capsules in treating angina pectoris of coronary heart disease (syndrome of Qi deficiency and blood stasis), evaluate the evidence quality and comprehensive value of Guanxinjing capsules in 6+1 dimensions involving 9 aspects, and clarify the clinical positioning and advantages of this medicine. MethodsA qualitative combined with quantitative evaluation method was adopted, involving clinical medicine, epidemiology, evidence-based medicine, and pharmacoeconomics. Through public data collection, questionnaire surveys, real-world data collection, and literature comprehensive evaluation, an evaluation system involving 9 aspects in 6+1 dimensions was constructed for Guanxinjing capsules. Experts assigned weights to the criterion layer and indicator layer, and the multi-criteria decision analysis (MCDA) model and CSC (V2.0) were employed to measure each dimension and reveal the clinical value of Guanxinjing capsules. Results①The evaluation results showed that Guanxinjing capsules are safe. According to the adverse reactions in the instructions, the systematic evaluation and meta-analysis of clinical safety, and the data collected by the National Center for Adverse Drug Reaction Monitoring, the adverse reactions of Guanxinjing capsules mainly include chest tightness, dyspnea, dizziness, and digestive system-related symptoms, with a standardized score of 0.75 points, which suggests good safety. ②The meta-analysis results suggest that according to the same efficacy standards, the effectiveness of Guanxinjing capsules alone and Guanxinjing capsules combined with conventional Western medicine or Chinese patent medicines is higher than that of conventional Western medicine or the Chinese patent medicine Shenshao capsules alone in treating coronary heart disease. The standardized score of effectiveness is 0.57, which indicates that the effectiveness still requires evidence support. ③With the individual disposable income in 2020 as the expected payment assumption threshold, compared with conventional treatment alone, combining Guanxinjing capsules with conventional treatment is cost-effective and economical for the patients with angina pectoris of coronary heart disease under certain conditions (higher than 106.91 yuan), which suggests good economy. ④At present, 3 patents for the invention of Guanxinjing capsules have been approved, covering multiple fields such as clinical innovation, service system innovation, and industrial development, which implies good innovation. ⑤In addition, the questionnaire surveys for medical staff involve five different dimensions, and the statistical scores and evaluation results show good suitability of Guanxinjing capsules. ⑥The reimbursement rate of Guanxinjing capsules by residents is high. The sampling survey results show that Guanxinjing capsules are fully equipped in hospitals across China and have good accessibility. ⑦Derived from the theory of activating blood and resolving stasis proposed by Wang Qingren, a famous physician in the Qing Dynasty, Guanxinjing capsules integrate multiple therapies such as replenishing Qi, nourishing Yin, and aromatic warming and unblocking. According to the analysis data in the "6+1" dimensions, the clinical comprehensive evaluation score of Guanxinjing capsules for angina pectoris of coronary heart disease (syndrome of Qi deficiency and blood stasis) was 0.73. ConclusionThe results of comprehensive evaluation of each dimension and clinical value suggest that Guanxinjing capsules in treating angina pectoris of coronary heart disease (syndrome of Qi deficiency and blood stasis) have sufficient clinical evidence, good safety, suitability, and accessibility. It is recommended that Guanxinjing capsules can be included in the documents of basic clinical medication management in accordance with the established procedure.

Objective To study the seasonal distribution characteristics of polycyclic aromatic hydrocarbons (PAHs) in PM2.5 in Lianyungang City, and analyze the sources of PAHs pollution, and to evaluate the health risks of PAHs in different seasons. Methods PM2.5 samples were collected regularly from January 2019 to December 2023, and 16 types of PAHs were determined by HPLC. Kruskal-Wallis H test was used to compare the concentrations of PM2.5 and PAHs in different years and seasons. The source of PAHs was analyzed by characteristic ratio and principal component analysis (PCA). Health risks were assessed using the BaP equivalent method and the incremental lifetime cancer risk (ILCR) model. Results The annual exceedance rates of PM2.5 and BaP in Lianyungang showed a decreasing trend from 2019 to 2023. PM2.5, total PAHs and PAHs monomers (except Ace, Flu and Acy) all showed significant seasonal differences, with the highest concentration in winter (P<0.001). The average proportion of 4-ring PAHs was the highest and the average proportion of 2-ring PAHs was the lowest. The proportion of 5-6 ring PAHs was relatively high in winter and spring. PM2.5and PAHs were negatively correlated with temperature, relative humidity and precipitation, and were positively correlated with atmospheric pressure. PM2.5 was negatively correlated with wind speed, while some PAHs monomers were positively correlated with wind speed. The characteristic ratio and PCA results showed that the main sources of PAHs in Lianyungang City were mixed sources of road dust and vehicle emissions, oil pollution sources and biomass combustion sources. The results of ILCR showed that the highest risk was found in adults, with males slightly higher than females. In Lianyungang, the maximum value of ILCR in winter was more than 10-6 in people over 9 years old. Conclusion The main sources of PAHs in PM2.5 in Lianyungang City are mixed sources of road dust and vehicle emissions, oil pollution sources, and biomass combustion sources. Under the current exposure level of PAHs in PM2.5, residents have a certain potential carcinogenic risk.

ObjectiveTo analyze the metabolomic characteristics of platelets in fibrinogen(FIB) overexpression rats of coronary heart disease with blood stasis syndrome(CHD-BSS), explore potential biomarkers, and investigate the mechanism of FIB overexpression on CHD-BSS. MethodsSD rats were randomly divided into BSS group and BSS+FIB overexpression group(BSS+FIB group), with 10 rats in each group. Both the BSS+FIB group and the BSS group were fed a high-fat diet combined with oral administration of vitamin D3 and subcutaneous injection of isoproterenol, but rats in the BSS+FIB group were overexpressed with FIB during the initial modeling stage by transfection with adeno-associated virus(AAV). The overexpression level of FIB in rat liver and plasma samples was detected by enzyme-linked immunosorbent assay(ELISA) and real-time fluorescence quantitative polymerase chain reaction(Real time PCR), as well as the expression level of liver FIB A(FGA) mRNA. The characteristics of metabolites in rat platelet samples were analyzed by ultra-high performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry(UPLC-Q-Exactive Orbitrap-MS), and the differential metabolites between groups were screened by principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA), and the enriched pathways were analyzed. The accuracy of potential biomarkers in the diagnosis of CHD-BSS was evaluated by receiver operating characteristic(ROC) curve. The expression of autophagy related proteins phosphorylated adenosine monophosphate(AMP) activated protein kinase(p-AMPK)/AMPK, phosphorylated mammalian target of rapamycin(p-mTOR)/mTOR, microtubule-associated protein 1 light chain 3(LC3) Ⅱ/Ⅰ and p62 in platelets were detected by Western blot. ResultsCompared with the BSS group, the expression levels of FIB in liver and plasma samples of the BSS+FIB group were significantly increased(P<0.05, P<0.01), and the expression level of FIB mRNA in the liver was remarkably increased(P<0.01), indicating successful overexpression of FIB. Platelet metabolomics results showed significant differences in metabolic profiles between the BSS+FIB group and the BSS group, and a total of 25 significantly enriched metabolic pathways and 8 metabolites involved in these metabolic pathways, among which uric acid, guanosine and ribose 1-phosphate levels were up-regulated, while adenosine diphosphate(ADP), AMP, guanosine diphosphate(GDP), adenylosuccinate and norepinephrine levels were down-regulated. The diagnostic ability analysis of differential metabolites showed that all 8 differential metabolites had good diagnostic ability, with an area under the curve(AUC)>0.85. Western blot results showed that compared with the BSS group, the expression levels of p-mTOR/mTOR and p62 proteins in platelets of the BSS+FIB group was significantly reduced(P<0.01), while the expression levels of p-AMPK/AMPK and LC3Ⅱ/Ⅰ proteins were increased, but the difference was not statistically significant. ConclusionOverexpression of FIB can change the metabolic characteristics of CHD-BSS rat model, involving multiple aspects such as vascular endothelial injury, platelet activation and myocardial function damage. Among them, overexpression of FIB may enhance the occurrence of platelet autophagy, thereby inducing platelet activation and promoting thrombus formation.
