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 observe the clinical effect of modified Huanglian Wendantang on cardiovascular risk factors in patients with metabolic syndrome under the guidance of treating disease before its onset. MethodsA total of 82 patients with metabolic syndrome treated in the First Affiliated Hospital of Heilongjiang University of Chinese Medicine from July 2023 to July 2024 were selected and allocated into an observation group （41 cases） and a control group （41 cases） by the random number table method. The control group received routine treatment， and the observation group was treated with modified Huanglian Wendantang on the basis of routine treatment. Both groups were treated for 8 weeks. The therapeutic effects on TCM symptoms after treatment in the two groups were evaluated. The levels of obesity degree indicators， blood pressure indicators， glucose and lipid metabolism indicators， inflammatory factors， and vascular endothelial function indicators before and after treatment in the two groups were measured， and the treatment safety was evaluated. ResultsAfter treatment， the total response rate of TCM symptoms in the observation group was 97.56% （40/41）， which was higher than that （87.80%， 36/41） in the control group （χ²=5.205， P<0.05）. After treatment， both groups showed declines （P<0.05） in systolic blood pressure （SBD）， diastolic blood pressure （DBP）， triglyceride （TG）， total cholesterol （TC）， low density lipoprotein cholesterol （LDL-C）， fasting blood glucose， 2-hour postprandial blood glucose （2 h PG）， glycosylated hemoglobin （HbA1c）， fasting insulin （FINS）， Homeostatic Model Assessment for Insulin Resistance （HOMA-IR）， body mass index （BMI）， waist circumference （WC）， waist-to-hip ratio （WHR）， leptin （LEP）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， endothelin-1 （ET-1）， and inducible nitric oxide synthase （iNOS）. Moreover， the declines in the observation group were more obvious than those in the control group （P<0.05， P<0.01）. After treatment， both groups showed elevated levels of high density lipoprotein cholesterol （HDL-C）， adiponectin （ADP）， nitric oxide （NO）， and endothelial nitric oxide synthase （eNOS） （P<0.05）， and the above indexes in the observation group were higher than those in the control group （P<0.01）. ConclusionUnder the guidance of the thought of treating disease before its onset， modified Huanglian Wendantang was used to treat patients with metabolic syndrome. The decoction improved the clinical efficacy by ameliorating IR to improve insulin sensitivity， reducing inflammation， and protecting the vascular endothelial function. It inhibits cardiovascular risk factors without inducing adverse reactions， being worthy of clinical application and promotion.

Current experimental and computational methods have limitations in accurately and efficiently classifying ion channels within vast protein spaces. Here we have developed a deep learning algorithm, GPT2 Ion Channel Classifier (GPT2-ICC), which effectively distinguishing ion channels from a test set containing approximately 239 times more non-ion-channel proteins. GPT2-ICC integrates representation learning with a large language model (LLM)-based classifier, enabling highly accurate identification of potential ion channels. Several potential ion channels were predicated from the unannotated human proteome, further demonstrating GPT2-ICC's generalization ability. This study marks a significant advancement in artificial-intelligence-driven ion channel research, highlighting the adaptability and effectiveness of combining representation learning with LLMs to address the challenges of imbalanced protein sequence data. Moreover, it provides a valuable computational tool for uncovering previously uncharacterized ion channels.

Objective:To evaluate the incidence and case fatality rate of cardiovascular disease (CVD) among populations in urban and rural communities in eastern, central and western regions of China.Methods:The present study was based on the data of the Prospective Urban and Rural Epidemiology (PURE)-China cohort, which enrolled participants who had at least one follow-up visit and complete information on age and sex. Information on baseline demographics, cardiovascular risk factors, and prevention and treatment for CVD were collected. CVD and mortality events were documented using the standardized case report form of the PURE Global Study to assess the incidence and case fatality rate of CVD among populations in urban and rural communities in eastern, central and western China.Results:This study included a total of 47 262 community-dwelling participants (age: (51.1±9.6) years; female, n=27 529, 58.2%) from 115 urban and rural communities in 12 provinces across the eastern, central, and western regions of China. Over a follow-up period of 11.9 (9.5, 12.6) years, 2 686 deaths and 5 873 cardiovascular events were documented. The incidence of CVD was 11.90 (95%CI: 11.60-12.21)/1 000 person-years. A significant difference in CVD incidence was observed across regions ( Ptrend<0.001), which was highest in the western provinces (13.99 (95% CI: 13.33-14.65)/1 000 person-years), intermediate in the eastern provinces (11.92 (95% CI: 11.52-12.33)/1 000 person-years), and lowest in the central provinces (8.87 (95% CI: 8.25-9.50)/1 000 person-years). The 1-year case fatality rate of CVD demonstrated an increasing trend from eastern to western regions (eastern: 10.20% (95% CI: 6.95-14.73); central: 13.50% (95% CI: 9.90-18.14); western: 18.62% (95% CI: 14.95-22.94); Ptrend<0.001). Moreover, the incidence of major CVD was consistently higher in rural areas compared with urban areas across eastern ( P<0.001), central ( P=0.01) and western ( P<0.001)_regions, respectively. The 1-year case fatality rate in rural areas was also significantly higher compared with that in urban areas in both eastern ( P<0.001) and western regions ( P=0.02). Conclusions:The incidence and case fatality rate of CVD were high among middle-aged population in China, especially those in western regions with low socioeconomic levels and in rural areas.

ObjectiveTo observe the effect of Jiawei Shenqi Yixin prescription on cardiovascular risk factors in the patients with heart failure with preserved ejection fraction and insulin resistance. MethodFrom January 2021 to January 2022， a total of 82 patients with heart failure with preserved ejection fraction were enrolled in the ward of the First Affiliated Hospital of Heilongjiang University of Chinese Medicine.

The observation group was additionally treated with Jiawei Shenqi Yixin prescription for 8 weeks. The clinical efficacy， traditional Chinese medicine （TCM） efficacy， cardiac function indexes ［NT-probrain natriuretic peptide （NT-proBNP） and 6-min walking test （6MWT）］， echocardiographic parameters ［left atrial volume index （LAVI）， left ventricular mass index （LVMI）， peak early diastolic to peak late diastolic mitral flow velocity （E/A） ratio］， insulin resistance-related indexes ［fasting insulin （FINS）， fasting plasma glucose （FPG）， triglyceride （TG）， high-density lipoprotein cholesterol （HDL-C）， homeostatic model assessment of insulin resistance （HOMA-IR）， triglyceride-glucose index （TYG）， and triglyceride to high-density lipoprotein cholesterol （TG/HDL-C） ratio］， inflammatory cytokines ［tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， adiponectin （ADP）， and C-reactive protein （CRP）］， vascular endothelial function indicators ［nitric oxide （NO）， endothelial nitric oxide synthase （eNOS）， inducible nitric oxide synthase （iNOS）， and endothelin-1 （ET-1）］， and the safety of treatment were determined. In addition， Pearson correlation analysis was performed to analyze the correlations of insulin resistance， inflammatory cytokines， and vascular endothelial factors with the mitigation of heart failure. ResultIn terms of clinical efficacy， the therapy of the observation group was significantly effective in 26 patients， effective in 12 patients， ineffective in 3 patients， with the total effective rate of 92.68%， the therapy of the control group was significantly effective in 14 patients， effective in 12 patients， and ineffective in 15 patients， with the total effective rate of 63.41%. The clinical total effective rate of the observation group was higher than that of the control group （χ²=11.6， P<0.05）. In terms of TCM efficacy， the therapy of the observation group was significantly effective in 26 patients， effective in 11 patients， and ineffective in 4 patients， with the total effective rate of 90.24%； the therapy of the control group was significantly effective in 9 patients， effective in 13 patients， and ineffective in 19 patients， with the total effective rate of 53.66%. The TCM total effective rate of the observation group was higher than that of the control group （χ²=8.19， P<0.05）. Compared with those before treatment， the levels of NT-proBNP， LAVI， LVMI， FPG， FINS， HOMA-IR， TYG， TG/HDL-C， TNF-α， IL-6， CRP， ET-1， and iNOS in two groups declined after treatment （P<0.05）， while the levels of 6MWT， E/A， ADP， NO， and eNOS elevated （P<0.05）. After treatment， the observation group had lower levels of NT-proBNP， LAVI， LVMI， FPG， FINS， HOMA-IR， TYG， TG/HDL-C， TNF-α， CRP， and ET-1 （P<0.05） and higher levels of 6MWT， E/A， ADP， and NO than the control group （P<0.05）. In addition， the increase in 6MWT after treatment was positively correlated with the increase in NO and the decrease in ET-1. The decrease in LVMI after treatment was positively correlated with the increase in NO and the decrease in FINS. The increase in left ventricular ejection fraction after treatment was positively correlated with the decreases in TNF-α and TYG （P<0.05）. Adverse reactions were observed in neither group. ConclusionJiawei Shenqi Yixin prescription can significantly mitigate the symptoms， reduce inflammation， and improve vascular endothelial function in the patients with heart failure with preserved ejection fraction and insulin resistance， being safe without causing adverse reactions.

Objective:To investigate the effect of minimally invasive treatment of mild to moderate hallux valgus using frequency conversion waterflood ultrasound extracapsular osteotomy.Methods:The data of patients with mild to moderate hallux valgus who were treated with frequency conversion waterflood ultrasound extracapsular osteotomy at Department of Foot and Ankle Surgery, Xuzhou Renci Hospital from August 2017 to August 2020 were retrospectively analyzed. During the operation, the metatarsal bone was truncated outside the capsule of the medial joint of the first metatarsal head with frequency conversion waterflood ultrasound osteotomy to correct the hallux valgus deformity. The changes of hallux valgus angle (HVA), the first and second intermetatarsal angle (IMA), the distal articular surface angle of the first metatarsal bone (DMAA) and the range of motion(ROM) of the first metatarsophalangeal joint were compared before operation and at the last follow-up. The American Foot and Ankle Society (AOFAS) forefoot scoring system was used to evaluate the clinical effect. Measurement data with normal distribution were expressed as Mean±SD and analyzed by t-test. Results:A total of 32 patients (53 feet) were enrolled, including 6 males and 26 females; 28 left feet and 25 right feet; age (34.5±7.8) years old. All patients were followed up for (13.0±5.9) months. All osteotomy sites healed without metastatic metatarsalgia, infection and deformity recurrence. At the last follow-up, HVA, IMA, and DMAA were all improved compared with those before surgery [(11.25±1.59) ° vs. (33.45±4.45) °; (6.83±0.95) ° vs. (14.96±2.10) °; (6.26±1.92) ° vs. (23.64±4.72) °; all P<0.01], AOFAS forefoot score was significantly higher than that before operation (90.96±2.92 vs. 59.22±5.63, P<0.01). There was no significant difference in the ROM of the first metatarsophalangeal joint before and after operation ( P>0.05). Conclusions:The application of frequency conversion waterflood ultrasonic bone cutter combined with extracapsular osteotomy for minimally invasive treatment of mild to moderate hallux valgus has the advantages of small damage, inconspicuous scars, and reliable correction. It can be popularized in clinical practice.

Objective:To investigate the clinical, pathologic and radiologic features and molecular alterations in patients with primary cardiac leiomyosarcoma (PCLMS).Methods:Five cases of PCLMS were collected in Beijing Anzhen Hospital from January 2016 to December 2020. The clinical, pathologic and radiologic data, and molecular alterations were analyzed, and the patients were followed up.Results:All five patients were female, and had no history of leiomyosarcoma in other parts of the body. The age of patients ranged from 37 to 62 years (median 47 years). The main clinical symptoms were chest pain and dyspnea, one also presented with palpitation and lower limb weakness and one with dizziness. Two tumors were located in the left atrium, two in the right atrium, and one in the right ventricle, and they maximal diameter ranged from 2.5 to 14.0 cm (mean 6.2 cm). The neoplasms presented as medium-echo masses with a broad base in the echocardiography, and as a low-density, solid mass when detected by contrast-enhanced CT. Histologically, two tumors were well-differentiated and three were moderately and poorly differentiated, and two included extensive, loose myxoid stroma. Immunohistochemical staining showed that PCLMS was positive for SMA, desmin, MDM2, and epidermal growth factor receptor. Fluorescence in situ hybridization showed ALK gene rearrangement in two cases, and COL1A1-PDGFB fusion in three cases. All cases received surgical excision and two cases received chemotherapy. Three patients died within 0-11 months (mean survival of 7.7 months) and two patients were alive.Conclusions:PCLMS is a malignant tumor with a high recurrence rate and poor prognosis. These cases may provide useful information to improve the diagnosis and management of PCLMS.

Objective:To investigate the clinical significance of fluid-attenuated inversion recovery (FLAIR) vascular hyperintensities (FVHs) in patients with chronic atherosclerotic middle cerebral artery occlusion.Methods:From July 2016 to November 2020, patients admitted to the Department of Neurology, Jiangdu People's Hospital of Yangzhou and first found chronic atherosclerotic middle cerebral artery occlusion were enrolled. The demographic, clinical and MRI imaging data were collected. According to the presence or absence of acute cerebral infarction, they were divided into the non-acute cerebral infarction group and the acute cerebral infarction group. According to the modified Rankin Scale score at 3 months after the onset, patients with acute cerebral infarction were further divided into the good outcome group (≤2) and the poor outcome group (>2). A multivariate logistic regression model was used to analyze the independent correlation between FVHs and the risk of cerebral infarction in patients with chronic atherosclerotic middle cerebral artery occlusion and the outcome in patients with cerebral infarction. Results:A total of 94 patients with chronic atherosclerotic middle cerebral artery occlusion were enrolled, including 38 with non-acute cerebral infarction (40.4%) and 56 with acute cerebral infarction (59.6%). In patients with acute cerebral infarction, 13 (23.2%) had a poor outcome, and 43 (76.8%) had a good outcome. The fibrinogen level, the proportion of patients with FVHs and the FVHs score in the cerebral infarction group were significantly higher than those in the non-cerebral infarction group (all P<0.05). Multivariate logistic regression analysis showed that the FVHs score was significantly, independently, and positively correlated with the risk of acute cerebral infarction (odds ratio 2.524, 95% confidence interval 1.400-4.552; P=0.002). The National Institutes of Health Stroke Scale score at admission, the modified Rankin Scale score at admission, and FVHs score in the poor outcome group were significantly higher than those in the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that there was a significant independent negative correlation between the FVHs score and the outcome of patients with cerebral infarction (odds ratio 0.144, 95% confidence interval 0.045-0.459; P=0.001). Conclusions:FVHs suggest that the blood supply is in a state of decompensation. When FVHs are present, the risk of cerebral infarction in patients with chronic middle cerebral artery occlusion is significantly increased; the wider the range of FVHs, the higher the risk of poor outcome after cerebral infarction.
