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 establish a prediction model for high-risk cardiovascular disease (CVD) among residents aged 35 to 75 years, so as to provide the basis for improving CVD prevention and control measures. Methods: Permanent residents aged 35 to 75 years were selected from Dongcheng District, Beijing Municipality using the stratified random sampling method from 2018 to 2023. Demographic information, lifestyle, waist circumference and blood biochemical indicators were collected through questionnaire surveys, physical examinations and laboratory tests. Influencing factors for high-risk CVD among residents aged 35 to 75 years were identified using a multivariable logistic regression model, and a prediction model for high-risk CVD was established. The predictive effect was evaluated using the receiver operating characteristic (ROC) curve. Results: A total of 6 968 individuals were surveyed, including 2 821 males (40.49%) and 4 147 females (59.51%), and had a mean age of (59.92±9.33) years. There were 1 155 high-risk CVD population, with a detection rate of 16.58%. Multivariable logistic regression analysis showed that gender, age, smoking, central obesity, systolic blood pressure, fasting blood glucose, triglyceride and low-density lipoprotein cholesterol were influencing factors for high-risk CVD among residents aged 35 to 75 years (all P<0.05). The area under the ROC curve of the established prediction model was 0.849 (95%CI: 0.834-0.863), with a sensitivity of 0.693 and a specificity of 0.863, indicating good discrimination. Conclusion The model constructed by eight factors including demographic characteristics, lifestyle and blood biochemical indicators has good predictive value for high-risk CVD among residents aged 35 to 75 years.

BACKGROUND:Cervical disc herniation can cause pain in the neck and shoulder area,as well as radiating pain in the upper limbs.The incidence rate is increasing year by year and tends to affect younger individuals.Fully understanding the biomechanical characteristics of the cervical spine in adolescents is of great significance for preventing and delaying the onset of cervical disc herniation in this age group. OBJECTIVE:To reconstruct cervical spine models for both healthy adolescents and adolescent patients with cervical disc herniation utilizing finite element analysis techniques,to analyze the motion range of the C1-T1 cervical vertebrae as well as the biomechanical characteristics of the annulus fibrosus,nucleus pulposus,endplates,and the cartilage of the small joints. METHODS:A normal adolescent's cervical spine and an adolescent patient with cervical disc herniation were selected in this study.The continuous scan cervical spine CT raw image data were imported into Mimics 21.0 in DICOM format.The C1-T1 vertebrae were reconstructed separately.Subsequently,the established models were imported into the 3-Matic software for disc reconstruction.The perfected models were then imported into Hypermesh software for meshing of the vertebrae,nucleus pulposus,annulus fibrosus,and ligaments,creating valid geometric models.After assigning material properties,the final models were imported into ABAQUS software to observe the joint motion range of the C1-C7 cervical vertebrae segments under different conditions,and to analyze the biomechanical characteristics of the annulus fibrosus,nucleus pulposus,endplates,and small joint cartilage of each cervical spine segment. RESULTS AND CONCLUSION:(1)In six different conditions,the joint motion range of the C1 vertebra in the cervical spine models of both normal adolescent and adolescent patient with cervical disc herniation was higher than that of the other vertebrae.Additionally,the joint motion range of each cervical spine segment in normal adolescent was greater than that in adolescent patient with cervical disc herniation.(2)In the cervical spine model of normal adolescent,the maximum stress values in the annulus fibrosus and nucleus pulposus were found on the left side during C2-3 flexion conditions(0.43 MPa and 0.17 MPa,respectively).In the cervical spine model of adolescent patient with cervical disc herniation,the maximum stress values were found on the left side during C7-T1 flexion conditions(0.54 MPa and 0.18 MPa,respectively).(3)In the cervical spine model of normal adolescent,the maximum stress value on the endplate was found on the left side of the upper endplate of C3 during flexion conditions(1.46 MPa).In the model of adolescent patient with cervical disc herniation,the maximum stress value on the endplate was found on the left side of the lower endplate of C7 during flexion conditions(1.32 MPa).(4)In the cervical spine model of normal adolescent,the maximum stress value in the small joint cartilage was found in the C2-3 left rotation conditions(0.98 MPa).In adolescent patient with cervical disc herniation,the stress in the small joint cartilage significantly increased under different conditions,especially in C1-2,with the maximum stress found during left flexion(3.50 MPa).(5)It is concluded that compared to normal adolescent,adolescent patient with cervical disc herniation exhibits altered cervical curvature and a decrease in overall joint motion range in the cervical spine.In adolescent with cervical disc herniation,there is a significant increase in stress on the annulus fibrosus,nucleus pulposus,and endplates in the C7-T1 segment.The stress on the left articular cartilage of the C1-2 is notable.Abnormal cervical curvature may be the primary factor causing these stress changes.

BACKGROUND:The cervical facet joint,as an important anatomical structure of the posterior column of the cervical spine,plays an important role in neck activity,stress transmission,and maintaining cervical stability. In recent years,anatomical and biomechanical studies have shown that asymmetry of cervical facet joints can cause degeneration of facet joints,which may be the main cause of cervical spine degeneration in young people. Existing research is mostly focused on adults,and there are also reports on preschool and school-age children in China,while there are few reports on the morphological parameters of cervical facet joints in adolescents.OBJECTIVE:Through three-dimensional reconstruction of the cervical facet joints in adolescents,measuring their relevant morphological parameters,and comparing them with those in children and adults,we explored the age-related changes in the morphological development of cervical facet joints,providing a theoretical basis for the diagnosis,treatment,and prevention of cervical spondylosis arising from cervical facet joints.METHODS:A total of 62 adolescents aged 13-18 years were selected to undergo spiral CT scan of cervical vertebrae and 3D reconstruction,requiring no bone destruction,tumor,deformity,or fracture,no changes in vertebrae morphology and structure,no previous spinal operations. The guardian's informed consent to the experimental protocol was obtained. By age group,group A was 13-14 years old;group B was 15-16 years old;group C was 17-18 years old. Thecorrelation morphometry and statistical analysis of C2-C7 facet joints were performed in adolescents of each group.RESULTS AND CONCLUSION:(1) In three groups of subjects,the facet joint surface heights and widths displayed decreasing and increasing trends in relation to the change of vertebra order. The facet joint surfaces on the inferior surface showed larger height and width compared to the corresponding indicators on the superior surface. (2) The intra-articular height of the articular process was lowest in C5 among the three groups of ages,and it showed a positive correlation with age. (3) Among the three groups,the gaps between the articular surfaces of the joints in C4-5 of group A,C3-4 of group B,and C4-5 of group C weresignificantly larger than the rest of the gaps in each group. Except for C4-5,there were no significant differences between the two groups. Except for C2-3,the remaining gaps between the vertebrae in group C were significantly larger than those in the two groups. (4) It is indicated that the morphology of the cervical facet joint surface gradually transitions from circular to elliptical as the vertebral order increases. In inter-group comparison,facet joint surface height is significantly affected by age compared to facet joint surface width. The area of the lower facet joint surface of each segment is greater than that of the upper facet joint surface,with only significant differences in the shape and area of C4-5 and C5-6. In addition,the minimum height of the facet joint is located at C5,and the significantly widened gap between the facet joint surfaces is mainly located at C3-4 and C4-5. Therefore,cervical instability often occurs at the mid-level.

Objective:To investigate the role and molecular mechanisms of signal transducer and activator of tran-scription 3(STAT3)in the paraventricular nucleus(PVN)of the hypothalamus in regulating body weight and energy metabolism in mice.Methods:AAV2/9-hSyn-Cre-EGFP virus was stereotactically injected into the PVN of STAT3Flox/Flox mice to conditionally knock out(CKO)STAT3 in the PVN.STAT3 expression was verified via immunoflu-orescence staining and Western blot.Body weight and temperature were monitored,glucose tolerance was assessed using glucose tolerance tests in mice,and morphological changes in the liver,interscapular brown adipose tissue(IBAT),in-guinal white adipose tissue(IWAT),and quadriceps muscle were evaluated via hematoxylin-eosin(HE)staining.RT-qPCR was used to measure mRNA levels of platelet-derived growth factor receptor α(PDGFRα),peroxisome prolifera-tor-activated receptor γ(PPARγ),hormone-sensitive lipase(HSL),and adipose triglyceride lipase(ATGL)in these tissues.Results:STAT3 protein expression in the PVN of CKO mice was significantly reduced,and the number of STAT3-positive neurons was also decreased.Compared to wild-type(WT)mice,CKO mice exhibited increased body weight,impaired thermogenesis in IBAT,and reduced glucose tolerance.HE staining revealed lipid droplet accumula-tion in hepatocytes of the liver,enlarged adipocytes with hypertrophic lipid droplets and leukocyte infiltration in adipose tissues,and intermuscular fat deposition in the quadriceps muscle.RT-qPCR analysis showed decreased mRNA levels of PDGFRα,HSL,and ATGL in the liver;upregulated PPARγ mRNA but downregulated HSL and ATGL mRNA in IBAT and IWAT;and reduced PPARγ and HSL mRNA levels in the quadriceps muscle of CKO mice.Conclusion:The STAT3 signaling pathway in the PVN is critical for maintaining systemic energy balance and serves as a key node in met-abolic regulation.

This study was aimed at investigating the infection status of orf virus(ORFV)and the genetic evolution characteristics of epidemic ORFV isolates from Anhui province.A total of 303 clinical samples collected from major meat sheep breeding cities in An-hui during 2021-2023 were subjected to ORFV detection with fluorescence quantitative PCR(qPCR).The full-length B2L and F1L genes of ORFV in the positive samples were amplified through conventional PCR and sequenced.Genetic evolution analysis of the B2L and F1L genes was conducted after sequencing.The qPCR results indicated a total ORFV positivity rate in the clinical samples of 48.8%(148/303).Multiple sequence comparisons indicated that the B2L genes of 56 sample isolates shared 96.7%-100.0%DNA and 97.4%-100.0%amino acid sequence identity.Moreover,the F2L genes of 56 sample isolates shared 95.1%-100.0%DNA and 95.0%-100.0%amino acid sequence identity.The genetic evolution tree constructed with the B2L gene DNA sequences indicated sample iso-lates and 21 reference strains located in subgroup 1,and 26 sheep-derived sample isolates and 17 reference strains located in sub-group 2.Among them,the goat-derived sample isolate FY-TYA was located in the same sub-branch as the human-derived reference strain Gansu,whereas the goat-derived sample isolate FY-XQC was located in the same sub-branch as the reference strains China Vaccine and OV-HLJ-04.The genetic evolution tree constructed with the F1L gene DNA sequences showed,the goat sample isolates FY-XQA and FY-XQC were located in the same sub-branch as the sheep-derived reference strain Xinjiang.ORFV infection was rela-tively widespread in the major meat sheep breeding areas of Anhui province,and the DNA and amino acid sequences of the B2L and F1L genes of current circulating ORFV isolates showed different degrees of genetic variation,among which F1L gene had a high de-gree of variation.Furthermore,some goat-derived sample isolates were closely related to human,vaccine,and sheep-derived refer-ence strains.These results may serve as a reference for the prevention and control of ORFV infection in Anhui province.

Objective To identify risk factors associated with lymphatic leakage after laparoscopic radical prostatectomy(LRP)and to develop a machine learning-based nomogram for predicting such outcomes to support clinical prevention strategies.Methods We retrospectively analyzed perioperative data from 248 patients who underwent radical prostatectomy for prostate cancer between January 2020 and January 2024.Independent risk factors were identified through univariate and multivariate logistic regression analyses.A predictive model was developed,and its diagnostic performance was assessed by the area under the receiver operating characteristic curve(AUC).Five-fold cross-validation was performed to evaluate the model's generalizability.A nomogram was subsequently constructed to facilitate individualized risk quantification.Results Among the 248 patients,89(35.9%)developed lymphatic leakage,while 159(64.1%)did not.Independent risk factors for lymphatic leakage included intraopera-tive lymph node dissection(OR=5.415,95%CI:2.167～13.532,P<0.001),intraoperative plasma transfusion(OR=2.952,95%CI:1.524～5.718,P=0.001),and postoperative fasting duration of≥2 days(OR=1.412,95%CI:1.089～1.829,P=0.009).The predictive model showed good discrimination and calibration(AUC=0.711,95%CI:0.647～0.776,P<0.001;sensitivity:0.764;specificity:0.597).Model robustness was confirmed through five-fold cross-validation(training set AUC=0.822;test set AUC=0.829).The nomogram provided a clinically useful tool for quantifying individual risk of lymphatic leakage.Conclusions Intraoperative lymph node dissection,plasma transfusion,and postoperative fasting lasting≥2 days are independent risk factors for lymphatic leakage following radical prostatectomy.The validated predictive model demonstrates favorable clinical utility.
