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.

ObjectiveTo investigate the effects of jatrorrhizine on endogenous metabolites and metabolic pathways in the mouse model of ulcerative colitis. MethodsThirty male C57BL/6J mice were randomly divided into the normal group， the model group， the low-dose and high-dose jatrorrhizine groups （0.04， 0.16 g·kg^-1）， and the mesalazine group （0.52 g·kg^-1）The mouse model of ulcerative colitis was established with 3% dextran sulfate sodium （DSS） and treated with different doses of jatrorrhizine by gavage. The changes in body weight， colon length， disease activity index （DAI）， and colonic histopathology were analyzed to evaluate the therapeutic effects of jatrorrhizine. UPLC-Q-TOF/MS was employed to determine the serum and fecal levels of metabolites in mice. Metabolomics methods were used to screen the differential metabolites， on the basis of which the potential therapeutic mechanism of jatrorrhizine on DSS-induced ulcerative colitis in mice was investigated. ResultsAfter intervention with jatrorrhizine， the model mice showed significantly decreased DAI（P<0.05，P<0.01）， recovered colon length，（P<0.05，P<0.01） and alleviated histopathology of the colon. The metabolomics study screened out 13 differential metabolites in the serum and 8 differential metabolites in the feces. The pathway enrichment analysis predicted three potential metabolic pathways： Biosynthesis of unsaturated fatty acids， phenylalanine， tyrosine and tryptophan biosynthesis， and phenylalanine metabolism. ConclusionJatrorrhizine may treat ulcerative colitis by regulating the biosynthesis and metabolism of amino acids and the synthesis of unsaturated fatty acids.

ObjectiveThis study employed the scoping review method to systematically retrieve and analyze the basic information and clinical research evidence of expensive Chinese patent medicines （CPMs）， aiming to provide a basis for future related research and clinical applications. MethodsEight Chinese and English databases were systematically searched for the clinical research evidence on expensive CPMs. ResultsEleven expensive CPMs （Angong Niuhuang Wan， Jufang Zhibao Wan， Suhexiang Wan， Pien Tze Huang， Niuhuang Qingxin Wan， Qinggong Shoutao Wan， Compound Realgar Natural Indigo Tablets， Xihuang Wan， Dingkun Wan， Babao Wan， and Guilingji Capsules） were selected. A total of 365 related studies were included in this review， comprising 331 clinical studies （of which 291 were randomized controlled trials）， 30 systematic reviews and Meta-analyses， 3 expert consensus， and 1 rapid health technology assessment. Among the 11 CPMs， 2（Angong Niuhuang Wan and Jufang Zhibao Wan） had a daily price over 500 yuan. The famous and precious Chinese medicinal materials involved included Moschus （frequency of 7）， Bovisc Alculus （7）， and Borneol （5）. The dosage forms included pills， capsules， oral liquid， tablets， and lozenges. The diseases treated by these CPMs mainly included malignant tumors， cerebrovascular diseases， gynecological diseases， and hepatobiliary system diseases. The sample sizes of the clinical studies were mainly concentrated within the range of 51-100 cases， and the main control form was CPM + basic Western medicine treatment vs. basic Western medicine treatment. The 331 clinical studies reported a total of 44 adverse events occurred， of which 36 were determined to be adverse reactions. ConclusionThe scarcity of raw materials leads to the high prices of expensive CPMs. The difficulty of conducting clinical research and the critical and severe cases treated lead to a lack of clinical research evidence with large sample sizes. The uneven distribution of existing studies， incomplete information on medicine package， and non-standard clinical research designs remain to be addressed in the future.

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:Exercise as a form of active rehabilitation can improve the dysfunction caused by peripheral nerve injury,and different exercise modalities target different lesion sites and recovery mechanisms. OBJECTIVE:To comprehensively analyze the application and mechanisms of different exercise modalities in functional recovery from peripheral nerve injury. METHODS:A computerized search was conducted in PubMed and CNKI databases for relevant literature published before January 2024.The search terms used were"peripheral nerve injury,spinal cord,exercise,cerebral cortex,muscle atrophy,mirror therapy,blood flow restriction training"in both English and Chinese.Finally,77 articles were included for review. RESULTS AND CONCLUSION:Peripheral nerve injury can cause systemic pathological changes such as skeletal muscle atrophy,corresponding spinal cord segmental lesions,and sensorimotor cortex remodeling.Aerobic exercise can improve dysfunction by enhancing the immune response,promoting glial cell polarization,and promoting the release of nerve growth factor.Blood flow restriction exercise can regulate the secretion of muscle growth factor,promote muscle growth and enhance muscle strength.Mirror movement has a good effect in activating the cerebral cortex and reducing cortical remodeling.Different exercise modalities have potential benefits in functional recovery after peripheral nerve injury;however,there are still some problems and challenges,such as the choice of exercise modalities,the control of exercise intensity and frequency,and the detailed analysis of mechanisms.

Objectives:This study aims to evaluate the causal relationship between plasma proteins and myocardial infarction(MI)using two-sample bidirectional Mendelian randomization(MR)analysis,identify key biomarkers,and validate their expression.Methods:The study utilized publicly available genome-wide association study(GWAS)data of 4 907 plasma proteins as the exposure factor,with single nucleotide polymorphisms(SNPs)as instrumental variables,and four MI datasets as outcomes.Two-sample MR analysis was performed using the inverse variance weighted(IVW)method,complemented by simple model,weighted model,weighted median estimator(WME),and MR-Egger regression methods to assess the causal relationship between exposure factors and outcomes.Venn diagrams and word clouds were used to screen proteins associated with MI as candidate biomarkers.Reverse MR analysis was conducted to evaluate reverse causality.Sensitivity analysis was performed to assess the robustness of the results.Immunohistochemistry(IHC)was used to validate the expression of proteasome activator subunit 1(PSME1)and vacuolar protein sorting 29(VPS29)in the aorta of mice,and enzyme-linked immunosorbent assay(ELISA)was used to verify the expression of PSME1 and VPS29 in plasma from patients with acute myocardial infarction(AMI).Results:The two-sample MR analysis indicated that PSME1 was significantly negatively associated with myocardial infarction in all four datasets,with OR(95%CI)of 0.684(0.557-0.839),0.990(0.987-0.993),0.579(0.448-0.748),and 0.993(0.990-0.996),respectively,with all P<0.001.Similarly,VPS29 also showed a significant negative association with MI in all four datasets,with OR(95%CI)of 0.902(0.862-0.945),0.998(0.997-0.999),0.866(0.808-0.929),and 0.998(0.997-0.999),respectively,with all P<0.001.Reverse MR analysis did not detect reverse causality,and sensitivity analysis confirmed the robustness of the results.IHC results showed significantly reduced expression of PSME1 and VPS29 in the aortas of AMI mice with an atherosclerotic background compared to control mice(both P<0.05).ELISA results indicated significantly lower plasma levels of PSME1 and VPS29 in AMI patients compared to healthy controls(both P<0.05).Conclusions:Higher levels of PSME1 and VPS29 are negatively associated with the risk of MI,suggesting that PSME1 and VPS29 may serve as protective biomarkers for cardiovascular diseases.

Objective:Investigation of the relationship between variant angina pectoris syncope and coronary artery spastic targeted location, arrhythmias, and coronary artery stenostic lesion.Methods:This study combined retrospective and prospective registry approaches. Data were sourced from the case database of Henan province "Multicenter Clinical Observation Study of Variant Angina Pectoris". A total of 507 patients with variant angina pectoris who had complete records from June 1980 to December 2022 were consecutively enrolled. Select patients among them who experienced syncope, and analyze the target vessel sites of coronary artery spasm, arrhythmias during variant angina pectoris attacks, and the degree of stenosis in coronary artery lesions.Results:Among 507 variant angina pectoris patients, 88 experienced syncope. Age was (53.9±9.7) years and 66 patients (75.0%) were male. Forty patients (45.5%, 40/88) were aged 50-59 years. The incidence of syncope in variant angina pectoris caused by left anterior descending artery (LAD) spasm, right coronary artery (RCA) spasm, and multivessel coronary artery spasm was 7.4% (15/202), 22.7% (42/185), and 23.6% (25/106), respectively. The latter two were significantly higher than those in the LAD group ( P all<0.05). Among 77 patients with variant angina pectoris syncope, definitive electrocardiogram recordings were available during syncope episodes. All patients exhibited arrhythmias during syncope: 34 cases involved tachyarrhythmias and 43 cases involved bradyarrhythmias. The incidence of rapid arrhythmias in patients with LAD, RCA, and multi-vessel spasm syncope was 72.7% (8/11), 24.3% (9/37), and 54.2% (13/24), respectively, with P<0.05 for the first two. Bradyarrhythmias occurred in 27.3% (3/11) of LAD, 75.7% (28/37) of RCA, and 45.8% (11/24) of multivessel coronary artery spasm syncope cases, with the first two showing P<0.05. Coronary angiography analysis of 56 syncope patients revealed target vessel locations and stenosis severity: 12 patients had LAD lesions and 41 had RCA lesions, stenosis ≥50% occurred in 66.7% (8/12) and 43.9% (18/41) of these lesions, respectively ( P>0.05). Conclusions:Variant angina pectoris syncope predominantly affects middle-aged males. Bradyarrhythmias triggered by RCA spasm are a common cause, while the incidence of syncope shows no significant correlation with the degree of coronary artery stenostic lesion, whether in the LAD or the RCA.

Objective:To summarize and analyze the clinical characteristics of patients with antibody mediated rejection (AMR) after lung transplantation at China-Japan Friendship Hospital, thereby providing references for clinical management.Methods:A retrospective study was conducted by collecting clinical data of 34 lung transplant recipients (LTRs) diagnosed with AMR between March 2017 and September 2023. The diagnosis of AMR was based on the 2019 International Society for Heart and Lung Transplantation (ISHLT) consensus. Baseline characteristics, primary diseases, pre-diagnostic events, diagnosis, treatment regimens, and outcomes were summarized and analyzed. According to outcomes at the final follow-up (March 31, 2024), patients were divided into survival group (22 cases) and death group (12 cases), and the differences in clinical characteristics and treatments were compared.Results:The incidence of AMR among 551 LTRs was 6.2% (34/551). Among the 34 AMR recipients, 79.4% (27/34) were male, and the median age was 64.0 (54.5, 67.3) years. The primary underlying disease was interstitial lung disease (79.4%). Based on diagnostic classification, 73.5%(25/34) were clinical AMR and 26.5% (9/34) were subclinical AMR. Regarding diagnostic levels, 11.8%(4/34) were proven AMR, 50.0% (17/34) probable AMR, and 38.2%(13/34) possible AMR. Pre-transplant sensitization was detected in 2 patients (5.9%). Post-transplant HLA antibody testing revealed 79.4%(27/34) positive for HLA class Ⅱ antibodies (most commonly DQ7) and 85.3%(29/34) had newly developed HLA antibodies, of which 82.4%(28/34) were de novo donor-specific antibodies (DSA). The most common clinical manifestations were exertional dyspnea(67.6%) and decreased pulse oxygen saturation(47.1%). Chest imaging mainly showed new consolidations or patchy opacities (55.9%), followed by ground-glass opacities (32.4%) and pleural effusion (20.6%). Regarding treatment, 94.1% (32/34) received intravenous immunoglobulin (IVIG), 88.2%(30/34) underwent plasma exchange, and 41.2%(14/34) received intravenous glucocorticoid (IVGC). The most common regimens were "plasma exchange+IVIG" and "IVGC+plasma exchange+IVIG+rituximab", each used in 23.5%(8/34) of cases. The complete HLA antibody clearance rate after treatment was 38.2%. The mortality rates at 3 months, 1 year, and final follow-up after AMR diagnosis were 8.8%, 23.5%, and 35.3%, respectively, with a median survival time of 243.0(96.3, 572.3) days. The survival group had a significantly higher rate of tacrolimus-based triple immunosuppressive therapy (glucocorticoid+tacrolimus+mycophenolate moftil) compared to the death group [86.4% (19/22) vs 50.0% (6/12), P=0.040], while rituximab usage was higher in the death group [75.0% (9/12) vs 13.6% (3/22), P=0.008]. Conclusions:Although AMR after lung transplantation is relatively rare, its diagnosis is challenging, antibody clearance rate after treatment is low, and clinical outcomes are poor, requiring heightened clinical vigilance.

AIM:To investigate the effects of the Qingfei-Jiedu-Huatan formula(QJHF)on damage to the lung vascular endothelial barrier induced by Klebsiella pneumoniae in mice with severe pneumonia,as well as to elucidate its underlying mechanisms.METHODS:Fifty-one C57BL/6J mice were randomly divided into control group(n=6),model group(n=15),QJHF group(n=15),and ceftriaxone sodium(CRO)group(n=15).Severe pneumonia was in-duced in the mice by a single tracheal intubation with 50 μL of 1×1011 CFU/mL Klebsiella pneumoniae on day 0.Six hours after modeling,the mice in QJHF and CRO groups received their respective treatments,while those in control and model groups were administered an equal volume of saline.All mice were sacrificed on day 3 after the end of gavage.Lung histo-pathological changes were assessed using hematoxylin-eosin(HE)staining.Levels of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),and IL-6 in lung tissues were measured by enzyme-linked immunosorbent assay(ELISA).Flow cytometry was used to detect CD11b+Ly6g+cells in bronchoalveolar lavage fluid(BALF).Proteomics and network pharma-cology analyses were conducted to elucidate the mechanisms of drug action.Western blot was conducted to assess the ex-pression levels of vascular endothelial cadherin(VE-cadherin),zonula occludens-1(ZO-1),occludin,vascular endothe-lial growth factor(VEGF),P38 mitogen-activated protein kinase(P38),and phosphorylated P38(p-P38)in lung tis-sues.RESULTS:Treatment with QJHF significantly attenuated the symptoms such as mental status and respiratory dis-tress,reduced mortality,mitigated lung tissue lesions,and decreased levels of IL-6,TNF-α,IL-1β,as well as BALF to-tal protein concentration,total cell count and neutrophil content in a mouse model of severe pneumonia(P＜0.05 or P＜0.01).Additionally,QJHF increased the expression of VE-cadherin,ZO-1 and occludin proteins in lung tissues.Pro-teomic analysis demonstrated that QJHF modulated the expression of 129 proteins in the lung tissues of mice suffering from severe pneumonia.Network pharmacology identified 328 potential targets associated with 14 major bioactive components of QJHF and 1 665 genes related to severe pneumonia,with 125 overlapping genes between the two datasets.The construc-tion of a protein-protein interaction(PPI)network,along with Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses of the regulated proteins and overlapping genes,indicated that QJHF primarily in-fluenced the PI3K-Akt,MAPK and Rap1 signaling pathways,as well as VEGFR.Western blot analysis showed that QJHF significantly inhibited the expression of VEGF and P38 in lung tissues(P＜0.05 or P＜0.01).CONCLUSION:Treatment with QJHF attenuates severe pneumonia in mice,potentially by inhibiting VEGF/P38 signaling to protect the vascular endothelial barrier.
