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 investigate the correlation between carotid-femoral pulse wave velocity(cfPWV)and carotid artery structural,hemodynamic,and cardiac functional parameters.Methods:A total of 420 healthy volunteers who underwent neck ultrasound,cardiac ultrasound,and cfPWV examination at Kailuan General Hospital from June 2022 to February 2023 were selected,and they were divided into two groups based on the atherosclerosis threshold value of cfPWV>10 m/s,which included high cfPWV group(140 cases,cfPWV>10 m/s)and low cfPWV group(280 cases,cfPWV≤10 m/s).The demographic data(age,sex)of 420 persons were collected,and the common carotid artery diameter(CCAD),common carotid artery intima-media thickness(CIMT),plaque status,peak systolic velocity(PSV),end-diastolic velocity(EDV)and mean flow velocity(MFV)were compared between two groups.Then,the differences of interventricular septal thickness(IVST)of heart,left ventricular posterior wall thickness(LVPWT),the ratio of blood flow velocity at early stage to that at advanced stage in mitral valve(E/A)and stroke volume(SV)were analyzed.Multivariate logistic regression was adopted to analyze the independent influence factors of cfPWV enhancement.Results:The average age of high cfPWV group was(61.31±9.66)years old,which was significantly higher than(51.06±10.47)years old of low cfPWV group,and the difference of that was significant(t=-9.56,P<0.01).In the parameters of common carotid artery,63 persons(45.0%)occurred plaque in 140 persons of high cfPWV group,which was significantly lower than 50 persons(17.86%)in 280 persons of low cfPWV group,and the difference of that between two groups was significant(x2=34.97,P<0.05).The differences of CCAD,CIMT,PSV,EDV and MV of common carotid artery at right side of persons between two groups were significant(t=-2.16,-5.40,4.52,5.59,5.04,P<0.05),respectively.The parameters of heart showed that the LVPWT thickness increased(9.35±1.13)mm,and the ratio of E/A<1 increased 77.86%in high cfPWV group,which were significantly related to the increase of cfPWV(r=0.27,0.38,P<0.01).Multivariate logistic regression analysis indicated that age(OR=1.05,95%CI:1.02-1.08),CCAD(OR=1.63,95%CI:1.22-2.16),plaque presence(OR=1.84,95%CI:1.07-3.17),LVPWT(OR=1.35,95%CI:1.05-1.72),and the ratio of E/A<1(OR=2.37,95%CI:1.32-4.26)were independent predictors of cfPWV enhancement.Conclusion:The enhancement of cfPWV is closely related to high age,the reconstruction of common carotid artery(widening of inside diameter,and plaque formation),left ventricular hypertrophy,and diastolic abnormality,which indicates it is possible that atherosclerosis process accompanies by the change of interaction mechanism of blood vessels-heart.

Background/Aims: Treatment indications for patients with chronic hepatitis B (CHB) remain contentious, particularly for patients with mild alanine aminotransferase (ALT) elevation. We aimed to evaluate treatment effects in this patient population. Methods: This rollover study extended a placebo-controlled trial that enrolled non-cirrhotic patients with CHB and ALT levels below two times the upper limit of normal. Following 3 years of randomized intervention with either tenofovir disoproxil fumarate (TDF) or placebo, participants were rolled over to open-label TDF for 3 years. Liver biopsies were performed before and after the treatment to evaluate histopathological changes. Virological, biochemical, and serological outcomes were also assessed (NCT02463019). Results: Of 146 enrolled patients (median age 47 years, 80.8% male), 123 completed the study with paired biopsies. Overall, the Ishak fibrosis score decreased in 74 (60.2%), remained unchanged in 32 (26.0%), and increased in 17 (13.8%) patients (p<0.0001). The Knodell necroinflammation score decreased in 58 (47.2%), remained unchanged in 29 (23.6%), and increased in 36 (29.3%) patients (p=0.0038). The proportion of patients with an Ishak score ≥ 3 significantly decreased from 26.8% (n=33) to 9.8% (n=12) (p=0.0002). Histological improvements were more pronounced in patients switching from placebo. Virological and biochemical outcomes also improved in placebo switchers and remained stable in patients who continued TDF. However, serum HBsAg levels did not change and no patient cleared HBsAg. Conclusions In CHB patients with minimally raised ALT, favorable histopathological, biochemical, and virological outcomes were observed following 3-year TDF treatment, for both treatment-naïve patients and those already on therapy.

Background/Aims: Despite the high efficacy of direct-acting antivirals (DAAs), approximately 1–3% of hepatitis C virus (HCV) patients fail to achieve a sustained virological response. We conducted a nationwide study to investigate risk factors associated with DAA treatment failure. Machine-learning algorithms have been applied to discriminate subjects who may fail to respond to DAA therapy. Methods: We analyzed the Taiwan HCV Registry Program database to explore predictors of DAA failure in HCV patients. Fifty-five host and virological features were assessed using multivariate logistic regression, decision tree, random forest, eXtreme Gradient Boosting (XGBoost), and artificial neural network. The primary outcome was undetectable HCV RNA at 12 weeks after the end of treatment. Results: The training (n=23,955) and validation (n=10,346) datasets had similar baseline demographics, with an overall DAA failure rate of 1.6% (n=538). Multivariate logistic regression analysis revealed that liver cirrhosis, hepatocellular carcinoma, poor DAA adherence, and higher hemoglobin A1c were significantly associated with virological failure. XGBoost outperformed the other algorithms and logistic regression models, with an area under the receiver operating characteristic curve of 1.000 in the training dataset and 0.803 in the validation dataset. The top five predictors of treatment failure were HCV RNA, body mass index, α-fetoprotein, platelets, and FIB-4 index. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the XGBoost model (cutoff value=0.5) were 99.5%, 69.7%, 99.9%, 97.4%, and 99.5%, respectively, for the entire dataset. Conclusions Machine learning algorithms effectively provide risk stratification for DAA failure and additional information on the factors associated with DAA failure.
