To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Objective:To develop a Protection Motivation Questionnaire(PMQ)for frailty management in the elderly based on the Protection Motivation Theory(PMT), and test its reliability and validity.Methods:Guided by PMT, the initial questionnaire items were formulated through literature review, semi-structured interviews, and Delphi expert consultation.A total of 551 elderly patients with frailty from a tertiary hospital in Changsha were investigated.Item screening was conducted via critical ratio method, Cronbach's α coefficient, correlation analysis, and factor analysis.The reliability was assessed through internal consistency and test-retest reliability, while validity was evaluated via content validity and structural validity.Results:The final PMQ comprised 25 items across five dimensions: severity, susceptibility, response efficacy, response cost, and self-efficacy.The overall Cronbach's α coefficient was 0.818, with subscale coefficients ranging from 0.701 to 0.821.The split-half reliability was 0.811, test-retest reliability was 0.929, and content validity indexwas 0.86.Exploratory factor analysis extracted five factors, accounting for 52.0% of the cumulative variance.Confirmatory factor analysis demonstrated good model fit( χ2/df=1.626, RMSEA=0.05, CFI =0.914). Conclusions:The developed questionnaire exhibits strong reliability and validity, serving as an effective tool to assess protection motivation for frailty management in the elderly.

Objective:To investigate the expression of miRNAs in thymus of patients with myasthenia gravis(MG)and the re-lated mechanism of action,so as to provide theoretical and experimental basis for clinical diagnosis and treatment.Methods:miRNA microarray technology was used to analyze the differential miRNA expression in MG patients thymus.Fluorescence quantitative PCR and in situ hybridization were used to verify the expression of miR-19a-3p in thymus tissue.The TALL-104 cell line was transfected with miR-19a-3p mimics to observe the effects of miR-19a-3p on cell proliferation,apoptosis and expressions of related molecules(BCL2 and SOCS3).Results:Compared to normal thymus tissue,a total of 282 differentially expressed miRNAs were detected in the thymus of MG patients,among which 103 were up-regulated and 179 were down-regulated.The target genes of differentially expressed miRNAs were mainly related to nuclear molecules,cytoplasmic membrane-like structures and organelle related molecules.Quantita-tive fluorescence PCR and in situ fluorescence hybridization confirmed that the expression of miR-19a-3p in MG patients thymus was significantly lower than that in normal control group.Compared with the control group,miR-19a-3p mimics transfection could signifi-cantly inhibit the apoptosis of TALL-104 cells,increase the expression of BCL2 and decrease the expression of SOCS3(P<0.05).Conclusion:The expression of miRNA in the thymus of MG patients is significantly different from that of non-MG patients,and miR-19a-3p inhibits T cell apoptosis through up-regulation of BCL2 and down-regulation of SOCS3.

[Objective]To discuss the effect of Jiawei Shengji Yuhong Ointment on wound healing of rat model after anal fistula operation and its internal mechanism.[Methods]Seventy SD rats were randomly divided into blank group,Vaseline group(model group),Kangfuxin liquor group(control group),Jiawei Shengji Yuhong Ointment group(experimental group),ammonium pyrrolidine dithiocarbamate(PDTC)+vaseline group(PDTC+model group),PDTC+Kangfuxin liquid group(PDTC+control group),PDTC+Jiawei Shengji Yuhong Ointment group(PDTC+experimental group).The damp-heat wound model of rats after anal fistula operation was established and treated with different drugs.At the same time,PDTC intervention group was given intraperitoneal injection of nuclear factor-κB(NF-κB)signaling pathway inhibitor PDTC for 5 consecutive days on the basis of drug intervention.The wound healing of rats in each group was recorded,and the wound healing rate of rats in each group was calculated.On the 3rd,7th and 14th days,the granulation tissues of rats in each group were taken for Western blot and immunohistochemistry to detect the protein expression of NF-κB p65.The expression of interleukin-1β(IL-1β)and vascular endothelial growth factor(VEGF)was detected by enzyme-linked immunosorbent assay(ELISA).Hematoxylin-eosin(HE)staining was used for histomorphological observation.[Results]Compared with other groups,the experimental group and PDTC+experimental group could significantly shorten the wound healing time,and the wound healing rates of PDTC+experimental group and experimental group were higher(P＜0.05).HE staining results also confirmed that PDTC+experimental group can effectively promote the rapid growth of granulation tissue.The results of immunohistochemistry and Western blot showed that was inhibited significantly in experimental group and PDTC+experimental group the protein expression of NF-κB p65 in rat wound tissue,and the difference was statistically significant compared with the other groups(P＜0.05).The results of ELISA showed that the content of IL-1 β in each group decreased gradually at 3,7 and 14 d after treatment,and the content of IL-1[3 in PDTC+experimental group was the lowest(P＜0.05).The content of VEGF in each group increased gradually,and the content of VEGF in PDTC+experimental group and experimental group was the highest(P＜0.05).[Conclusion]Jiawei Shengji Yuhong Ointment can inhibit the expression of NF-κB p65 and IL-1 β protein and up-regulate the expression of VEGF protein through NF-κB signaling pathway,thereby promoting the angiogenesis of vascular endothelial cells,reducing inflammation,and promoting the wound healing after anal fistula surgery.

Objective:To prepare seven standard strains of 2019 novel coronavirus (2019-nCoV), including wild type (WT) strain, Beta variant, Delta variant, Omicron variants (BA.2, BA.5, BQ.1, XBB.1 branches), which could be used to apply for national standard strains.Methods:According to cytopathic effect (CPE), virus titer, whole-virus-genome-sequencing and detection of mycoplasma, the basic biological characteristics of clonal isolation were determined through plaque purification technology.Results:The CPE was mainly characterized by cell shrinkage and exfoliation in Vero cells after infection with seven 2019-nCoV clonal isolations (WT, Beta, Delta, Omicron, BA.2, BA.5, BQ.1 and XBB.1 branches). The result of mycoplasma detection were negative and titers of the clonal isolation from 2nd to 5th generations were stable at 10 5-10 8 TCID 50/ml; the electron microscope showed that the virions were all round or elliptical, with a diameter between 60 nm and 140 nm. The subtypes of 7 strains were identified by whole-virus-genome-sequencing and phylogenetic analysis, with genomic stability after the fifth successive generations of clonal isolation. Conclusions:The series clonal isolation of 2019-nCoV with typical CPE of coronavirus, clear morphological structure, good viral activity and stable genetic characteristics were prepared, and they could be used to apply for national standard strains.

Nuclear receptor corepressor (NCoR1) interacts with various nuclear receptors and regulates the anabolism and catabolism of lipids. An imbalance in lipid/energy homeostasis is also an important factor in obesity and metabolic syndrome development. In this study, we found that the deletion of NCoR1 in intestinal epithelial cells (IECs) mainly activated the nuclear receptor PPARα and attenuated metabolic syndrome by stimulating thermogenesis. The increase in brown adipose tissue thermogenesis was mediated by gut-derived tricarboxylic acid cycle intermediate succinate, whose production was significantly enhanced by PPARα activation in the fed state. Additionally, NCoR1 deletion derepressed intestinal LXR, increased cholesterol excretion, and impaired duodenal lipid absorption by decreasing bile acid hydrophobicity, thereby reversing the possible negative effects of intestinal PPARα activation. Therefore, the simultaneous regulatory effect of intestinal NCoR1 on both lipid intake and energy expenditure strongly suggests that it is a promising target for developing metabolic syndrome treatment.

Colorectal cancer is one of the common malignant tumors with high morbidity， and changes in lifestyle， dietary structure and environment in China in recent decades have been associated with an increase in the incidence of colorectal cancer. A large number of studies have shown that traditional Chinese medicine（TCM） can be used as a complementary and alternative treatment for colorectal cancer after conventional western medicine treatment. TCM physicians have accumulated a lot of clinical experience in the treatment of patients with stage Ⅰ-Ⅲ colorectal cancer， and have proved that TCM has unique efficacy， but there is still a lack of relevant clinical practice guidelines to standardize and guide the diagnosis and treatment of TCM. Based on this， according to the guideline development process of the World Health Organization Handbook for Guideline Development and the Clinical Evidence Grading Criteria on TCM Based on Evidence Body， under the framework of relevant laws， regulations and technical guidance documents， combined with the evidence of relevant domestic and foreign clinical research in recent years for evidence grading and opinion recommendation， and then the Guidelines for TCM Intervention After Conventional Western Medicine Treatment for Stage Ⅰ-Ⅲ Colorectal Cancer were developed by expert consensus. This guideline introduces the etiology， pathogenesis， syndrome differentiation and treatment of TCM intervention for colorectal cancer， which can provide guiding opinions for TCM clinicians and clinicians of integrated traditional Chinese and western medicine engaged in the prevention and treatment of colorectal cancer.
