ObjectiveTo investigate the effects of different antiplatelet therapy regimens （aspirin versus clopidogrel at specific doses） on cognitive function， blood biomarkers and brain imaging biomarkers when used prophylactically in patients with cerebral small vessel disease （CSVD）. MethodsA randomized controlled trial was conducted involving 160 CSVD patients who were randomly assigned to four groups： aspirin group （ASA）， low-dose clopidogrel group （CLOP-50）， standard-dose clopidogrel group （CLOP-75）， and control group （HC）. Cognitive function ［auditory verbal learning test-immediate recall （AVLT-IR）， auditory verbal learning test-short-delay recall （AVLT-SDR）， auditory verbal learning test-long-delay recall （AVLT-LDR）， hamilton anxiety rating scale （HAMA）， and hamilton depression rating scale （HAMD）， ADL（activities of daily living scale ）， （ascertain dementia 8-item questionnaire，AD8）］， blood biomarkers ［platelet count （PLT） and mean platelet volume （MPV）］， and CSVD-related imaging biomarkers ［white matter hyperintensities （WMH） and cerebral microbleeds （CMB）］ were assessed in all groups at baseline and at the 6-month follow-up. ResultsAfter 6 months of treatment， within-group comparisons showed that， compared with baseline， the ASA group had significantly increased scores on the AVLT immediate recall （AVLT-IR）， short-delay recall （AVLT-SDR）， and long-delay recall （AVLT-LDR） （P<0.05）. The CLOP-75 group showed significantly decreased HAMA and HAMD scores （P<0.05）， along with a significant increase in AVLT-LDR scores （P<0.05）. The number of CMBs increased from baseline in both the ASA and CLOP-75 groups （P<0.05）， whereas no statistically significant changes in blood biomarkers were observed in either group. By contrast， the CLOP-50 and HC groups showed no significant changes in cognitive function， blood biomarkers， or CSVD-related imaging biomarkers compared with baseline （all P<0.05）. Comparisons between groups showed that the AVLT-LDR scores and the number of CMBs increased faster in the ASA group than in the HC group （β=-0.187， P=0.04； β=-0.805， P<0.001）. In addition， the rate of CMB increase was also faster in the ASA group than in the CLOP-50 group （β=-0.695， P<0.01）. The ADL scores increased faster in the HC group than in the ASA group （β=0.170， P=0.02）. The AD8 scores decreased faster in the CLOP-75 group than in the HC group （β=-0.128， P=0.04）， but the rate of CMB increase in the CLOP-75 group was also faster than that in the HC group （β=0.604， P=0.04）. ConclusionIn CSVD patients， aspirin 100 mg or clopidogrel 75 mg improves cognitive function but increases the risk of cerebral hemorrhage. Clopidogrel 50 mg shows no short-term clinical benefit or imaging improvement.

Diannan Su's bone-setting school is one of the orthopedic schools of traditional Chinese medicine(TCM),and Su Caichen,a famous bone-setting physician in Diannan,is the key figure of Diannan Su's bone-setting school.This paper systematically summarized Su Caichen's bone-setting academic thoughts of"adaptation","harmonization"and"recovery",presented his core bone-setting concepts of"original traumatic chamber","bone-setting prior to activating blood and vessles,bone-setting together with soothing tendons and then fracture healing naturally after the removal of stasis",and introduced his five kinds of bone-setting manipulations for treating the common upper limb fractures in detail,namely shaking and pushing manipulations for distal radius fracture,floating manipulations for fracture of both ulna and radius,five-step manipulations for supracondylar fractures of humerus,staging manipulations for humeral shaft fracture,and degloving manipulations for proximal humeral fractures complicated with shoulder dislocation.Su Caichen's bone-setting academic thoughts,bone-setting concepts and his specific TCM bone-setting manipulations have constructed the academic and theoretical system of Diannan Su's bone-setting school,which will provide an approach for TCM treatment of orthopedic diseases,and will promote the inheritance and development of the specific TCM orthopedic schools.

Hepatitis B virus（HBV）infection poses a significant global health burden，with chronic infection driving progression to cirrhosis，hepatic failure，and hepatocellular carcinoma（HCC）. Mounting evidence implicates immune dysfunction and microbiota dysbiosis as core drivers of disease progression across all HBV infection stages. Gut and tissue-specific microbiota alterations disrupt innate/adaptive immunity，fueling inflammation，immunosuppression，and tumor immune evasion in chronic and end-stage disease. This review synthesizes mechanisms of immune-microbiota interplay in HBV pathogenesis and explores their translational potential for diagnostics and targeted interventions，including microbiota modulation and microbial biomarker applications.

Bacteria and their derivatives-mediated tumor therapy is an emerging therapeutic strategy. This strategy uses bacteria or bacterial derivatives as drug carriers to deliver drugs to tumor tissues through the targeting and motility of bacteria or bacterial derivatives and utilizes their special biological characteristics to cooperate with other therapies. In this review, the mechanism and advantages of bacteria-mediated tumor therapy were summarized, focusing on the combined application of bacterial therapy and chemotherapy, photothermal therapy, and radiotherapy, which improves the therapeutic effect through a synergistic effect. At the same time, the characteristics, structure, and composition of bacterial derivatives of bacterial outer membrane vesicles (OMVs) and minicells and their application in tumor therapy were also summarized. Although there are still some problems to be solved in the treatment of tumors mediated by bacteria and their derivatives, their potential to colonize in tumors and induce immune responses cannot be ignored. This therapy also provides new ideas for tumor therapy.

Objective:To analyze the factors influencing the teaching competence of anesthesiology residents in online theoretical courses, and to improve the teaching competence of residents.Methods:This single-center cross-sectional study included residents who participated in teaching the "Miller lectures" from September 2022 to January 2024. The primary outcome was the theoretical teaching competence of residents. Questionnaires were distributed to the audience after each lecture, and questionnaire scores were used to evaluate the teaching competence. Potential influencing factors included age, sex, grade, education level, theoretical knowledge, preparation time, involvement of junior and senior supervisors in guidance, and their teaching competence. The independent factors influencing the teaching competence of residents were analyzed using a multivariable linear regression model. A statistical analysis was conducted using R language (version 4.2.1).Results:This study included 44 anesthesiology residents, with an average teaching competence score of (9.34±0.34) (on a 10-point scale). The multivariable regression model revealed that grade (third year: coefficient 0.22, 95%CI 0.03 to 0.40, P=0.024), education level (master: coefficient 0.19, 95%CI 0.03 to 0.36, P=0.024; Doctor: coefficient 0.30, 95%CI 0.12 to 0.47, P=0.002), and junior supervisors' teaching competence (coefficient 0.97, 95%CI 0.70 to 1.24, P<0.001) were independent factors affecting resident teaching competence. Conclusions:In teacher-guided online theoretical courses with residents as the main lecturers, higher grade, education level, and teaching competence of guiding teachers are associated with high teaching competence of anesthesiology residents.
