ObjectiveNeuroinflammation plays a crucial role in both the onset and progression of ischemic stroke, exerting a significant impact on the recovery of the central nervous system. Excessive neuroinflammation can lead to secondary neuronal damage, further exacerbating brain injury and impairing functional recovery. As a result, effectively modulating and reducing neuroinflammation in the brain has become a key therapeutic strategy for improving outcomes in ischemic stroke patients. Among various approaches, targeting immune regulation to control inflammation has gained increasing attention. This study aims to investigate the role of in vitro induced regulatory T cells (Treg cells) in suppressing neuroinflammation after ischemic stroke, as well as their potential therapeutic effects. By exploring the mechanisms through which Tregs exert their immunomodulatory functions, this research is expected to provide new insights into stroke treatment strategies. MethodsNaive CD4⁺ T cells were isolated from mouse spleens using a negative selection method to ensure high purity, and then they were induced in vitro to differentiate into Treg cells by adding specific cytokines. The anti-inflammatory effects and therapeutic potential of Treg cells transplantation in a mouse model of ischemic stroke was evaluated. In the middle cerebral artery occlusion (MCAO) model, after Treg cells transplantation, their ability to successfully migrate to the infarcted brain region and their impact on neuroinflammation levels were examined. To further investigate the role of Treg cells in stroke recovery, the changes in cytokine expression and their effects on immune cell interactions was analyzed. Additionally, infarct size and behavioral scores were measured to assess the neuroprotective effects of Treg cells. By integrating multiple indicators, the comprehensive evaluation of potential benefits of Treg cells in the treatment of ischemic stroke was performed. ResultsTreg cells significantly regulated the expression levels of both pro-inflammatory and anti-inflammatory cytokines in vitro and in vivo, effectively balancing the immune response and suppressing excessive inflammation. Additionally, Treg cells inhibited the activation and activity of inflammatory cells, thereby reducing neuroinflammation. In the MCAO mouse model, Treg cells were observed to accumulate in the infarcted brain region, where they significantly reduced the infarct size, demonstrating their neuroprotective effects. Furthermore, Treg cell therapy notably improved behavioral scores, suggesting its role in promoting functional recovery, and increased the survival rate of ischemic stroke mice, highlighting its potential as a promising therapeutic strategy for stroke treatment. ConclusionIn vitro induced Treg cells can effectively suppress neuroinflammation caused by ischemic stroke, demonstrating promising clinical application potential. By regulating the balance between pro-inflammatory and anti-inflammatory cytokines, Treg cells can inhibit immune responses in the nervous system, thereby reducing neuronal damage. Additionally, they can modulate the immune microenvironment, suppress the activation of inflammatory cells, and promote tissue repair. The therapeutic effects of Treg cells also include enhancing post-stroke recovery, improving behavioral outcomes, and increasing the survival rate of ischemic stroke mice. With their ability to suppress neuroinflammation, Treg cell therapy provides a novel and effective strategy for the treatment of ischemic stroke, offering broad application prospects in clinical immunotherapy and regenerative medicine.

Benign prostatic hyperplasia （BPH） is a common chronic progressive disease in middle-aged and elderly men， characterized by prostate enlargement and bladder outlet obstruction， leading to symptoms such as frequent urination， urgency， and difficulty urinating. The pathogenesis of BPH involves factors such as aging， hormonal metabolic abnormalities， inflammatory responses， and imbalances in cell proliferation and apoptosis. Currently， the main treatment methods for BPH include medication， physical therapy， and surgical intervention. However， medication may cause side effects like sexual dysfunction and hypotension， physical therapy has limited efficacy， and surgery carries risks and postoperative complications. Therefore， there is an urgent need to find safer and more effective treatment options. Traditional Chinese medicine （TCM）， with its focus on treatment based on syndrome differentiation and a holistic approach， offers therapeutic advantages through multiple pathways and mechanisms. Recent studies have shown that TCM regulates pathways such as phosphoinositide-3-kinase/protein kinase B （PI3K/Akt）， nuclear factor-κB （NF-κB）， mitogen-activated protein kinases （MAPK）， nuclear factor E₂-related factor 2/antioxidant response element （Nrf2/ARE）， androgen receptor （AR）， transforming growth factor-β （TGF-β）/Smad， and hypoxia-inducible factor-1α/vascular endothelial growth factor （HIF-1α/VEGF） to inhibit oxidative stress and inflammatory response， reduce prostate cell proliferation， and promote apoptosis， thus exerting therapeutic effects. This article summarizes and analyzes the roles of these signaling pathways in the occurrence and development of BPH and the mechanisms of TCM intervention， aiming to provide scientific evidence for clinical treatment and drug development for BPH.

ObjectiveTo explore the correlation between the occurrence of cardiovascular events in rheumatoid arthritis（RA） and traditional Chinese medicine（TCM） syndrome. MethodsThe cross-sectional study selected 6713 RA patients from 122 centres nationwide， in which general information such as name， gender， age， height， body weight， and course of disease were collected by completing a questionnaire； patients were classified into eight types of syndrome according to the information of their four examinations，i.e. wind-dampness obstruction syndrome， cold-dampness obstruction syndrome， dampness-heat obstruction syndrome， phlegm-stasis obstruction syndrome， stasis-blood obstructing collateral syndrome， qi-blood deficiency syndrome， liver-kidney insufficiency syndrome， and qi-yin deficiency syndrome. According to the occurrence of cardiovascular events， they were divided into the occurrence group and the non-occurrence group， and the condition assessment data and laboratory examination indexes were recorded. The test of difference between groups was used to analyse the possible risk factors for the occurrence of RA cardiovascular events， and binary logistic regression was used to analyse the correlation between TCM syndromes and RA cardiovascular events. ResultsA total of 6713 RA patients were included， including 256 cases in occurrence group and 6457 in non-occurrence group. There was no statistically significant difference between groups in terms of height， gender， insomnia， appetite， white blood cell（WBC）， hemoglobin（HGB）， platelets（PLT）， rheumatoid factor（RF）， anti-cyclic peptide containing citrulline（CCP）， alanine aminotransferase（ALT）， aspartate aminotransferase（AST）， γ-glutamyl transpeptidase（GGT）， urea creatinine（CREA）， and glucose（GLU）（P＞0.05）. The TCM syndromes between groups showed significant statistic differences（P＜0.05）. Patients in occurrence group had longer disease duration， heavier body weight， and older age； more severe conditions such as disease activity（DAS-28）， number of painful joints（TJC）， number of swollen joints（SJC）， health questionnaire scores（HAQ）， visual analog scores（VAS）， restlessness， and fatigue； higher blood sedimentation rate（ESR）， low-density lipoprotein（LDL-C）， triglyceride（TG）， total cholesterol（TC）， D-Dimer， and lower high-density lipoprotein（HDL-C）（P＜0.05）. The distribution of syndrome types showed that dampness-heat obstruction syndrome accounted for the largest proportion of patients in both groups and was higher in RA cardiovascular events. Logistic regression analysis showed that the occurrence of RA cardiovascular events was strongly associated with dampness-heat obstruction syndrome［OR=5.937， 95%CI （4.434， 7.949）， P＜0.001］. ConclusionThe occurrence of RA cardiovascular events were associated with TCM syndromes， and the probability of cardiovascular events in the RA patients with dampness-heat obstruction syndrome was 5.937 times higher than patients with other TCM syndromes.

Objective To analyze the current oral health status of middle-aged and elderly people in Wuhan,and to provide clinical evidence for preventing and promoting oral health among middle-aged and elderly people.Methods The data was col-lected from the annual health examination data system of Wuhan,which included 1994 patients aged 45～95.According to the World Health Organization(WHO)"Basic Methods of Oral Health Survey"(5 th edition),the data of caries,periodontal disease,dentition defect,dentition loss and denture restoration was mainly studied.Statistical methods such as Chi-square test and vari-ance analysis were used for data analysis.Results Among the 1994 subjects,1613 people(80.89％)were male and 218 people(10.93％)were older than 75 years old.The average numbers of caries and teeth loss were 2.68 and 2.03,respectively.The mean number of caries and tooth loss increased with age.The mean numbers of caries and tooth loss in 45～,55～,65～,75～,and 85～95 years old groups were 0.98 and 0.54,1.82 and 1.39,3.21 and 2.48,7.65 and 6.04,12.65 and 9.91,respective-ly.The difference among different age groups was statistically significant(P＜0.01).The proportion of restoration of teeth loss was also elevated with the increase of age(P＜0.01),and the difference of community periodontal index(CPI)among different age groups was also statistically significant(P＜0.01).The proportion of people in CPI1 group(shallow periodontal pocket)was decreased with the increase of age,while the proportion of people in CPI2 group(deep periodontal pocket)was increased with the increase of age(P＜0.01).Conclusion The overall oral health examination results of middle-aged and elderly people in Wuhan shows that the oral health status is slightly better when compared with the result of urban area in the 4th National Oral Health Examination.But caries,periodontal disease,tooth loss and unrepaired dentures are still serious in the elderly population.It is necessary to improve the prevention awareness of oral diseases in the elderly through regular oral examination,timely detection and treatment.At the same time,attention should be paid to dental restoration in the elderly population to improve the quality of life.

Objective:To explore the utility of applying low frequency transcranial magnetic stimulation (rTMS) in the acute stage of ischemic stroke in terms of improving upper limb motor function.Methods:Eighty ischemic stroke survivors in the acute stage were randomly divided into a control group and an experimental group, with 40 in each. In addition to routine rehabilitation, the experimental group was given low frequency rTMS, while the control group was provided with sham rTMS. Before and after 4-weeks of treatment, upper limb motor function was evaluated using the Fugl-Meyer rating scale (FMA), Wolf motor function tests (WMFTs), the modified Barthel index (MBI) and in terms of motor evoked potential (MEP) latency and amplitude.Results:There were no significant differences between the two groups before the treatment. Afterward, however, the average FMA, WMFT, MBI scores had improved significantly more in the experimental group, on average, as had the average MEP amplitude.Conclusion:Low frequency rTMS in the acute phase of ischemic stroke can improve upper limb motor function and ability in the activities of daily living.

Objective:To compare clinical characteristics,treatment patterns and physiological indicators in bipolar disorder(BD)patients with different age of onset.Methods:Totally 380 patients with DSM-5 BD were se-lected in this study.Psychiatrists diagnosed the patients using the Mini International Neuropsychiatric Interview.The clinical information questionnaire and the Global Assessment of Functioning scale were utilized to collected clinical characteristics,treatment status,and physiological indicators.The onset age of BD was divided into 21 and 35 years as cut-off points.Multivariate logistic regression and linear regression were used to analyze related factors.Results:Among the 380 patients with BD,199 cases were early-onset group(52.4％),121 cases were middle-onset group(31.8％),and 60 cases were late-onset group(15.8％).There were 26.6％of patients in the early-onset group in-itially diagnosed as depression,23.1％in the middle-onset group,and 11.7％in the late-onset group.Multivariate analysis revealed that compared to the early-onset group of BD,the middle-onset(OR=2.22)and late-onset(OR=4.99)groups had more risk to experience depressive episodes,and the late-onset group(OR=6.74)had 6.74 times of risk to suffer from bipolar Ⅱ disorder.Additionally,patients in the middle-onset(β=-1.52)and late-on-set(β=-4.29)groups had shorter durations of delayed treatment,and those in the middle-onset(β=-1.62)and late-onset(β=-3.14)groups had fewer hospitalizations.Uric acid levels were lower in both the middle-onset(β=-28.39)and late-onset(β=-31.47)groups,and total cholesterol level was lower in the middle-onset group(β=-0.23).Conclusion:Patients with BD in different age of onset show significant differences in clinical charac-teristics,treatment conditions and physiological indicators.
