Objective: To investigate the association between the physical fitness index (PFI) and symptoms of depressive, anxiety and stress symptoms among college students, providing a reference for mental health interventions. Methods: From June to September 2025, combined convenience and cluster random sampling approach was used to administer questionnaire surveys and perform physical fitness tests on 2 712 college students from Zhejiang Chinese Medical University. The Depression Anxiety Stress Scales-21 Items (DASS-21) was used to assess mental health status. Chi square test and multivariate Logistic regression analysis were used to determine the associations between the PFI and the PFI component indicators with depressive, anxiety and stress symptoms. Results: The prevalence of depressive, anxiety and stress among college students were 24.26%, 33.22% and 13.68%, respectively. Statistically significant differences in the prevalence of these symptoms were detected across groups differing in sleep quality, physical activity, weekly breakfast frequency, and history of low back or neck pain ( χ 2=9.33-151.83, all P <0.05). After adjusting for confounding factors, Logistic regression revealed that the moderate and high PFI groups had significantly reduced risks of depressive and anxiety compared to the low PFI group ( OR =0.73, 0.63; 0.61, 0.72, all P <0.05). Poor speed (50 m run) and lower body strength (standing long jump) emerged as common risk factors affecting anxiety and depressive symptoms in both male and female college students (all P <0.05). Increased muscle strength (sit up for 1 min) in female students reduced the risk of depressive ( OR =0.81), anxiety ( OR =0.85), and stress symptoms ( OR =0.79) (all P <0.05). Enhanced lung capacity in male students decreased the risk of depressive ( OR =0.84) and anxiety symptoms ( OR =0.85) (both P <0.05). Conclusions The PFI is negatively correlated with depressive and anxiety symptoms among college students with notable gender differences. Insufficient speed and lower body explosive power represent common risk factors for mental health among male and female college students.

Alzheimer's disease (AD), a prototypical neurodegenerative disorder, encompasses multifaceted pathological processes. As pivotal cellular structures within the central nervous system, ion channels play critical roles in regulating neuronal excitability, synaptic transmission, and neurotransmitter release. Extensive research has revealed significant alterations in the expression and function of ion channels in AD, implicating an important role of ion channels in the pathogenesis of abnormal Aβ deposition, neuroinflammation, oxidative stress, and disruptions in calcium homeostasis and neural network functionality. This review systematically summarizes the crucial roles and underlying mechanisms of ion channels in the onset and progression of AD, highlighting how these channel abnormalities contribute to AD pathophysiology. We also discuss the therapeutic potential of ion channel modulation in AD treatment, emphasizing the importance of addressing multifactorial nature and heterogeneity of AD. The development of multi-target drugs and precision therapies is proposed as a future direction of scientific research.

OBJECTIVE: To compare the therapeutic efficacy and safety of local anesthesia and spinal anesthesia for the patients with varicocele (VC) who underwent microsurgical varicocelectomy (MV). METHODS: We retrospectively analyzed the data of VC patients who underwent MV treatment at the Andrology Department of the Affiliated Ruikang Hospital of Guangxi University of Chinese Medicine from May 2020 to March 2023. Cases with complete clinical data and follow-up evaluation were selected and divided into a control group (spinal anesthesia) and an observation group (local anesthesia) according to different anesthesia methods. The surgical time (including anesthesia time), visual analogue scale (VAS) score for pain, hospital stay, treatment cost, sperm concentration, forward motile sperm rate, and normal sperm morphology rate after three months of surgery, as well as postoperative complications and recurrence rate were compared between the two groups. RESULTS: A total of 107 eligible cases were included, with 56 cases in the control group and 51 cases in the observation group. There was no significant difference in the VAS score for pain during and after four hours of surgery, as well as postoperative complications, and recurrence rate between the two groups (P> 0.05). There was an significant increase in sperm concentration, forward motile sperm rate, and normal sperm morphology rate in both of two groups after three months of surgery (P<0.05). However, there was no significant difference between the two groups three months after surgery (P>0.05). The surgical time and hospital stay were shorter than those of the control group (P<0.05). And the treatment cost in observation group was lower than that of the control group (P<0.05). CONCLUSION Both local anesthesia and lumbar anesthesia for MV treatment of VC have good efficacy and safety. However, patients treated with MV under local anesthesia for VC have obvious advantages in terms of operation time (including anesthesia time), hospital stay, and treatment cost, which is worthy of clinical promotion and application.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

OBJECTIVE: The relationship between fish consumption and stroke is inconsistent, and it is uncertain whether this association varies across predicted stroke risks. METHODS: A cohort study comprising 95,800 participants from the Prediction for Atherosclerotic Cardiovascular Disease Risk in China project was conducted. A standardized questionnaire was used to collect data on fish consumption. Participants were stratified into low- and moderate-to-high-risk categories based on their 10-year stroke risk prediction scores. Hazard ratios ( HRs) and 95% confidence intervals ( CIs) were estimated using Cox proportional hazard models and additive interaction by relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (SI). RESULTS: During 703,869 person-years of follow-up, 2,773 incident stroke events were identified. Higher fish consumption was associated with a lower risk of stroke, particularly among moderate-to-high-risk individuals ( HR = 0.53, 95% CI: 0.47-0.60) than among low-risk individuals ( HR = 0.64, 95% CI: 0.49-0.85). A significant additive interaction between fish consumption and predicted stroke risk was observed (RERI = 4.08, 95% CI: 2.80-5.36; SI = 1.64, 95% CI: 1.42-1.89; AP = 0.36, 95% CI: 0.28-0.43). CONCLUSION Higher fish consumption was associated with a lower risk of stroke, and this beneficial association was more pronounced in individuals with moderate-to-high stroke risk.

Objective To study the mechanism of the amelioration of renal injury in immunoglobulin A nephropathy(IgAN)rats by multi-glycosides of Tripterygium wilfordii(GTW)based on the sphingosine kinase 1(Sphk1)/sphingosine 1-phosphate receptor 2(S1PR2)signalling pathway.Methods An IgAN rat model was established by means of bovine serum albumin gavage+castor oil and carbon tetrachloride subcutaneous injection+lipopolysaccharide tail vein injection.The rats were randomly divided into the model,control and experimental groups,with 9 rats in each group,and 10 normal rats were taken as the blank group.In the control group,6.25 mg·kg-1·d-1 prednisone was given by gavage;in the experimental group,9.375 mg·kg-1·d-1GTW was given by gavage;and in the blank and model groups,0.5 mL·100 g-1·d-1 0.9％NaCl was given by gavage,and the drugs were administered to the rats once a day in each group.At the end of the 15th week,urine samples were collected and blood albumin(ALB),blood urea nitrogen(BUN),24 hour-urine protein quantification(24 h-UTP),and urine erythrocyte counts were determined in each group,and the expression levels of Sphk1/S1PR2 proteins in each group were detected by Western blotting.Results The renal pathological changes in the control and experimental groups were significantly reduced compared with those in the model group by hematoxylin-eosin staining and immunofluorescence.The levels of ALB in the blank,model,control and experimental groups were(32.49±2.23),(22.98±0.51),(26.01±1.33)and(26.53±1.92)g·L-1;the levels of BUN were(6.11±1.71),(13.75±2.96),(6.71±1.35)and(4.77±0.99)mmol·L-1;the levels of 24 h-UTP were(5.72±1.96),(9.12±2.15),(5.78±2.05)and(4.75±1.50)mg·24 h-1;the urine erythrocyte counts were(9.73±2.40),(14.62±2.60),(9.90±1.59)and(9.46±2.94)cell·μL-1;the relative expression levels of Sphk1 protein were 0.85±0.02,1.47±0.02,1.06±0.02 and 1.09±0.02;the relative expression levels of S1PR2 protein were 0.27±0.02,0.88±0.01,0.43±0.02,and 0.42±0.02,respectively.The above indexes in the model group were statistically significant when compared with those of the control group and the experimental group(all P＜0.01).Conclusion GTW may reduce the proliferation of mesangial cells by inhibiting the Sphk1/S1PR2 signalling pathway,thus attenuating kidney injury in IgAN rats.

With the improvement of China's socioeconomic status,the issue of aging has become increasingly prominent,making cerebral infarction a common disease among the elderly.In recent years,research on cerebral infarction has gradually deepened,shifting focus from merely protecting and repairing neurons to emphasizing the complex interplay between inflammatory response and autophagy in the brain vascular unit,covering various aspects such as the blood-brain barrier,astrocytes,microglia,and autophagy.This shift in research direction has provided us with a profound understanding of the mechanisms underlying cerebral infarction,offering strong support for innovative future treatment strategies.In this review,we delved into the importance of the interplay between inflammatory response and autophagy in the pathogenesis of cerebral infarction,emphasized the intricate interactions among these biological components,which might lay the groundwork for more effective managements and treatments of cerebral infarction.By comprehensively reviewing existing literatures,we proposed future research directions,aiming to provide more scientific and systematic guidance for the clinical management and treatment of cerebral infarction.

Objective This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength. Methods We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.Results In the multimetal linear regression, Cu (β=-2.119), As (β=-1.318), Sr (β=-2.480), Ba (β=0.781), Fe (β= 1.130) and Mn (β=-0.404) were significantly correlated with grip strength (P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95％ confidence interval:-1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn (Pinteractions of 0.003 and 0.018, respectively).Conclusion In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

Objective To study the effects of different pellet feed hardness on the growth and reproduction,feed utilization rate,and environmental dust in laboratory mice.Methods One hundred of fifty 50 3-week-old SPF-grade C57BL/6JGpt and 150 ICR laboratory mice were randomly divided into three groups,with an equal number of males and females.They were fed diets with different hardness of 18.62 kg,23.15 kg,and 27.89 kg.Body weight,feed utilization rate,and dust levels in cages were recorded and calculated for mice aged 3-10 weeks.Forty-five 6-week-old male mice and ninety 4-week-old female mice from each strain were randomly divided into three groups and fed pellet feeds with three different hardness levels.After 2 weeks of adaptation to the same hardness feed,the mice were paired at a 1:2 male-to-female ratio and monitored for reproductive data for 3 months.Results At the age of 4 weeks,the body weight of male C57BL/6JGpt mice in 23.15 kg group was significantly higher than that in the 18.62 kg and 27.89 kg groups(P＜0.01),and the body weight of females in the 18.62 kg group was significantly higher than that in the 27.89 kg group(P＜0.05).There was no significant difference in body weight among ICR mice aged 3-10 weeks across different feed hardness groups(P＞0.05).For both strains,feed utilization rate for males was higher than that for females across different feed hardness groups at all weeks of age(P＜0.01).Compared to the 27.89 kg group,both the 18.62 kg and 23.15 kg groups showed a significant increase in the 50-mesh dust levels in cages for both strains aged 4-8 weeks(except for 7-week-old C57BL/6JGpt mice)(P＜0.05).For both C57BL/6JGpt and ICR mice,there was no significant difference in basic reproductive performance such as interval between the first litter and the monthly production index among the three feed hardness groups during the experimental period(P＞0.05).However,the monthly production index of C57BL/6JGpt mice first increased and then decreased with the increase of feed hardness,while that of ICR mice increased with increasing feed hardness,though these differences were not statistically significant(P＞0.05).Conclusion Different strains and genders had different tolerance to feed hardness.C57BL/6JGpt mice are more adapted to lower hardness feeds,while ICR mice are better suited to slightly higher hardness feeds.
