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 understand the correlation between autistic traits in children with autism spectrum disorder(ASD) and their parental behaviors, so as to provide evidence for improving social behavior in children with ASD. Methods: A total of 62 children aged 4-7 years diagnosed with ASD at Guangdong Provincial Work Injury Rehabilitation Hospital and Guangzhou Yuexiu District Children s Hospital from October 2021 to May 2025 were selected as the ASD group. A random number table method was used to select 62 healthy children of the same age from 3 ordinary kindergartens in Guangzhou as the control (typically developing,TD) group. The Parental Behavior Inventory and Social Responsiveness Scale were used to evaluate parental behaviors and autistic traits in both groups. The t-test and multiple linear regression were used to analyze the relationship between autistic traits in children with ASD and parental behaviors. Results: Compared with the TD group, the ASD group had significantly higher scores in social awareness, social cognition, social communication, social motivation, autistic behavior patterns, and the total score of social responsiveness, with statistically significant differences ( t =35.83, 46.17, 64.36, 41.45, 49.46,101.15, all P <0.01). The score of parental support/participation in the ASD group (24.61±4.30) was lower than that in the TD group (31.27±4.58), while the score of parental hostility/coercion in the ASD group (25.51±2.72) was higher than that in the TD group (12.75±2.72), with statistically significant differences ( t = -8.34, 26.14, both P <0.01). The total score of the Social Responsiveness Scale was negatively correlated with the dimension score of parental support/participation behaviors, and positively correlated with the dimension score of parental hostility/coercion behaviors ( r =-0.60, 0.91,both P <0.05). After adjusting for covariates such as children s age, gender, and primary caregiver, ASD children with exclusive breastfeeding ( β =-8.79) and parental support/participation behaviors ( β = -0.79 ) had a lower risk of autistic traits, while children with parental hostility/coercion behaviors ( β =4.62) had a higher risk of autistic traits (all P <0.05). Conclusion Autistic traits in children with ASD may be related to their parental behaviors and early feeding mode.

Objective To observe the performance and safety of self-developed real-time three-dimensional intracardiac echocardiography(ICE)system(system).Methods The self-developed system was constructed using disposable sterile real-time three-dimensional ICE catheter(catheter)and multifunctional cart-mounted digital ultrasound imaging host(ultrasound host).The diameter of catheter was 10F,with effective length of 90 cm and two-dimensional array transducer array(840 elements)integrated at tip.The ultrasound host was connected to the catheter through matching connector.The performance of this system was evaluated with self-made experimental equipment and standard phantom,and live animal experiment was performed to observe its safety and imaging quality.Results The maximum imaging depth of this system was ≥60 mm.Its axial resolution was ≤1 mm and lateral resolution was ≤1 mm within the depth of 40 mm,the horizontal and vertical geometric position accuracy errors were ≤10％and ≤5％,respectively,while the image geometric distortion was ≤10％,and the measurement volume error was ≤30％.The catheter was successfully inserted into right atrium of pig through femoral vein under ultrasound guidance,smoothly passing through the vascular pathway without any bending or jamming with good controllability.The cardiac images of this system were clear,which completely displayed cardiac chamber structures,and the image resolution met diagnostic requirement.No injury related to interventional procedures was found in laboratory tests nor anatomical results.Conclusion The self-developed ICE system was stable and safe,and initial results showed it could meet clinical application expectations.

BACKGROUND:With the continuous development of medical technology,the treatment of distal radius fractures is facing the need for more precise and personalized treatment.The traditional splint fixation method has some limitations in clinical application,which often has defects such as unstable fixation and easy to occur pressure sores.The validation of the improved 3D printed splint with rapid grid-free simulation is expected to lead to more accurate and effective treatment options for distal radius fractures.OBJECTIVE:To explore the design method of 3D printed splint for distal radius fracture based on clinical defect improvement and verify its clinical efficacy by rapid grid-free analysis.METHODS:Clinical defects of splint fixation of extended distal radius fracture were retrospectively analyzed,and 3D printed small splint was designed with specific improvement.The digital models of traditional splint and improved new 3D printed splint were made by Computer Aided Design drawing.Total,bone,soft tissue,and splint displacement and stress distribution were calculated through simulation analysis using rapid grid-free analysis tools.RESULTS AND CONCLUSION:(1)Compared with the traditional splint,the improved new 3D printing splint exerteded more balanced pressure on the skin without obvious stress concentration,and had better body surface adhesion.The displacement was smaller and the movement range was more reasonable.(2)An 3D printed splint based on clinical defect improvement can be designed.Rapid grid-free analysis verifies the advantages of the improved 3D splint,providing a basis for clinical application.

Ischemic stroke (IS) is a prevalent neurological disorder often resulting in significant disability or mortality. Resveratrol, extracted from Polygonum cuspidatum Sieb. et Zucc. (commonly known as Japanese knotweed), has been recognized for its potent neuroprotective properties. However, the neuroprotective efficacy of its derivative, (E)-4-(3,5-dimethoxystyryl) quinoline (RV02), against ischemic stroke remains inadequately explored. This study aimed to evaluate the protective effects of RV02 on neuronal ischemia-reperfusion injury both in vitro and in vivo. The research utilized an animal model of middle cerebral artery occlusion/reperfusion and SH-SY5Y cells subjected to oxygen-glucose deprivation and reperfusion to simulate ischemic conditions. The findings demonstrate that RV02 attenuates neuronal mitochondrial damage and scavenges reactive oxygen species (ROS) through mitophagy activation. Furthermore, Parkin knockdown was found to abolish RV02's ability to activate mitophagy and neuroprotection in vitro. These results suggest that RV02 shows promise as a neuroprotective agent, with the activation of Parkin-mediated mitophagy potentially serving as the primary mechanism underlying its neuroprotective effects.

Renal cell carcinoma in a transplanted kidney is rare, and partial nephrectomy in transplanted kidney is even more uncommon. A patient with papillary transplanted renal cell carcinoma who underwent partial nephrectomy was reported. The patient was admitted to the hospital due to the discovery of transplanted kidney mass, and the enhanced examination of CTU found a lesion in the upper pole of the transplanted kidney in the right iliac fossa, which may be renal cancer, with a diameter of about 2 cm. After open partial nephrectomy of the transplanted kidney, the postoperative pathology showed that the tumor was papillary renal cell carcinoma. The antirejection drugs were used after surgery. During the follow-up period of 16 months, there was no recurrence of transplanted kidney tumor.

Objective:To explore the clinical characteristics and prognostic factors of primary bladder adenocarcinoma（ACB）.Methods:The clinical data of 33 patients with primary ACB who underwent surgical treatment in the Department of Urology of Peking University Third Hospital from July 2003 to January 2024 were retrospectively analyzed. There were 5 females and 28 males，with an average age of（61.3 ± 11.5）years. Twelve patients had comorbidities（6 hypertension，2 coronary heart disease，5 diabetes mellitus，and 3 cerebrovascular diseases）and 12 had a smoking history. The mean body mass index（BMI）was（24.8 ± 3.2）kg/m 2. The maximum tumor diameter measured by enhanced computed tomography（CT）was（29.7 ± 12.7）mm. The preoperative neutrophil-to-lymphocyte ratio（NLR）was 3.4 ± 3.2，and the systemic immune-inflammation index（SII）was（582 ± 496）× 10 9/L.Patients were divided into two groups according to the surgical approach：the radical cystectomy group（ n = 23）and the bladder-sparing group（ n = 10）. For the radical cystectomy group，there were 19 males and 4 females，with a mean age of（59.9 ± 12.6）years. Five patients had comorbidities（3 hypertension，1 coronary heart disease，1 diabetes mellitus，and 2 cerebrovascular diseases）. Eight patients had a smoking history，with a mean BMI of（25.2 ± 3.5）kg/m 2. The maximum tumor diameter was（33.6 ± 10.9）mm，the preoperative NLR was 3.5 ± 3.5，and the SII was（618 ± 558）× 10 9/L. For the bladder-sparing group，there were 9 males and 1 female，with a mean age of（64.5 ± 8.2）years. Seven patients had comorbidities（3 hypertension，1 coronary heart disease，4 diabetes mellitus，and 1 cerebrovascular diseases）. Four patients had a smoking history，with a mean BMI of（23.5 ± 2.3）kg/m 2. The maximum tumor diameter was（20.7 ± 12.5）mm，the preoperative NLR was 3.1 ± 2.2，and the SII was（501 ± 323）× 10 9/L. Statistically significant differences were observed between the two groups in terms of comorbidities（ P = 0.008）and maximum tumor diameter（ P = 0.006），while no significant differences were found in other data（ P > 0.05）. The Kaplan-Meier survival curve was drawn，and Cox regression was used to analyze the prognostic factors of progression-free survival（PFS）and overall survival（OS）of patients. Results:Among the 33 patients，low-grade adenocarcinoma and high-grade adenocarcinoma accounted for 60.6% and 39.4% respectively according to the postoperative pathology，and 3 patients had positive surgical margins. There were 22 cases of muscle-invasive bladder adenocarcinoma，5 cases of lymph node metastasis，and 1 case of distant metastasis. The patients in tumor stages Ⅰ—Ⅳ were 9 cases（27.3%），8 cases（24.2%），7 cases（21.2%），and 9 cases（27.3%）respectively. Nine patients received postoperative adjuvant therapy，including 6 with adjuvant chemotherapy，2 with adjuvant chemotherapy combined with radiotherapy，and 1 with adjuvant immunotherapy. In the radical cystectomy group（ n = 23），there were 13 cases of low-grade and 10 cases of high-grade pathological grading，2 cases with positive margins，19 cases of muscle-invasive bladder adenocarcinoma，5 cases of lymph node metastasis，1 case of distant metastasis，and 5 patients received adjuvant therapy（4 cases of adjuvant chemotherapy，and 1 case of adjuvant immunotherapy）. In the bladder-sparing group（ n = 10），there were 7 cases of low-grade，3 cases of high-grade pathological grading，1 case with positive margins，3 cases of muscle-invasive bladder adenocarcinoma，zero lymph node or distant metastasis，and 4 patients received adjuvant therapy（2 cases of adjuvant chemotherapy，and 2 cases of combined adjuvant chemotherapy and radiotherapy）. A statistically significant difference was found in the proportion of muscle-invasive bladder adenocarcinoma between the two groups（ P = 0.006），while no significant differences were observed in other data（ P > 0.05）.The median follow-up duration of the patients was 28.0 months，the median PFS was 86.0 months，and the median OS was 90.0 months. The 2-year PFS and OS were 65.4% and 73.1% respectively. The 5-year PFS and OS were 54.2% and 56.5% respectively. The Kaplan-Meier survival analysis showed that there were no significant differences in PFS（ P = 0.777）and OS（ P = 0.585）between the radical cystectomy group and the bladder-preserving group. Female（ P = 0.011），BMI < 25 kg/m2（ P = 0.038），and positive surgical margins（ P < 0.01）were associated with poorer PFS. Aged ≥ 70 years（ P = 0.003），lymph node metastasis（ P = 0.041），and positive surgical margins（ P = 0.025）were associated with poorer OS，and patients in the adjuvant therapy group had better OS（ P = 0.005）. Multivariate Cox regression analysis indicated that positive surgical margins（HR 10.2， P = 0.012）were an independent impact factor for PFS，and positive surgical margins（HR 39.8， P = 0.001）and adjuvant therapy（HR 0.12， P = 0.021）were independent impact factors for OS. Conclusions:Positive surgical margins and adjuvant therapy are independent impact factors for the prognosis of patients with primary ACB.

OBJECTIVE To investigate the effects of borneol on pharmacodynamic and pharmacokinetic effects of Corydalis saxicola total alkaloids in depression model rats.METHODS Thirty male SD rats were divided into blank control group,negative control group,positive control group (fluoxetine 10 mg/kg,i.g.),single drug group (C.saxicola total alkaloids 210 mg/kg,i.g.) and combined drug group (C.saxicola total alkaloids 210 mg/kg+borneol 50 mg/kg,i.g.) according to the random number table method,with 6 rats in each group.By lipopolysaccharide (LPS) induction modeling,except blank control group (no model and no administration) received intraperitoneal injection of the same amount of normal saline,the rats in the other groups were intraperitoneally injected with LPS once a day to establish a rat model of depression.After 1 week of modeling,each administration group was given relevant drug intragastrically according to the corresponding dose,and blank control group and negative control group (without drug treatment) were administered intragastrically with an equal volume of solvent to dissolve the drug;continued modeling while administering the drug.After two weeks of continuous administration,the effects of C.saxicola total alkaloids versus the combination of C.saxicola total alkaloids and borneol on the behavior of depressed rats were tested by behavioral experiments;the levels of tumor necrosis factor-α,interleukin-1β and interleukin-6 in rats were determined;the histopathological changes of the hippocampus of rats were observed.Blood sample was collected from the orbit at different time points after administration on the 15th day,and the upper plasma was obtained.Ultra-performance liquid chromatography-triple quadrupole tandem mass spectrometry was established for the simultaneous determination of dehydrocarvedine,tetrahydropalmatine,coptisine,palmatine,jatrorrhizine,berberine,berberrubine and epiberberine in rat plasma.The average plasma concentration-time curve was depicted,the area under the curve (AUC) was calculated,and the pharmacokinetic parameters were analyzed by DAS 3.2.2 software.RESULTS Compared with blank control group,the negative control group had a decrease in body mass and sugar water preference rate,a decrease in the total distance of open field,a prolonged swimming immobility time,and a increased in the expression of inflammatory factors in serum (P<0.05);compared with negative control group,the single drug group and the combined drug group increased the preference rate of sugar water,increased the total distance of open field,shortened the time of swimming immobility,and decreased the expression of inflammatory factors in serum (P<0.05).There was no significant difference in the above indicators between the single drug group and the combined drug group in rats (P>0.05).Pharmacokinetic results showed that compared with single drug group,AUC0-t of coptisine,AUC0-t,AUC0-∞,tmax and cmax of jatrorrhizine,AUC0-t,AUC0-∞,t1/2 and cmax of berberrubine,and AUC0-t of epiberberine,cmax of dehydrocarvedine,cmax of palmatine were significantly increased in combined drug group,but there was no significant difference,indicating that borneol didn't have a significant effect on the efficacy of Corydalis saxicola nigra at this dose.CONCLUSIONS Both C.saxicola total alkaloids alone and in combination with borneol can improve depression-like behavior in depression model rats,reduce serum inflammatory cytokine levels,and protect hippocampal neurons.Compared with the use of Corydalis saxicola base alone,the combination with borneol do not show significant pharmacodynamic differences,bu can improve the absorption of coptisine,jatrorrhizine in model rats.

Objective:To investigate the endocardial myocardial biopsy and ultrastructural features of heart failure patients with reduced ejection fraction, to determine their histopathologic phenotype, and to explore the diagnostic utility of endomyocardial biopsy in such patients.Methods:A total of 35 patients with heart failure with reduced ejection fraction diagnosed at Beijing Anzhen Hospital and underwent endomyocardial biopsy were collected between January 2022 and December 2023. The clinical features, histopathological, and ultrastructural characteristics were analyzed and compared with 11 patients with heart failure with preserved ejection fraction.Results:The age ranged from 35-58 years, with median age of 51 years; there were 26 males and 9 females. Myocardial fibrosis and myocardial fiber disorders were the most common histopathologic changes [97.1% (34/35) and 74.3% (26/35), respectively]. Myocardial fibrosis was not statistically different between the heart failure with reduced ejection fraction group and the heart failure with preserved ejection fraction group [13.3% (5.7%-21.4%) vs. 13.2% (9.3%-34.2%), P=0.279]. Significant ultrastructural changes were dense mitochondrial proliferation, vacuolar degeneration, and disorganized arrangement of myocardial fibers with localized lysis and fracture. After endomyocardial biopsy, the etiology was identified in 11 patients (31.4%,11/35), with a prevalence of cardiac amyloidosis of 17.1% (6/35). Conclusions:Endomyocardial biopsy is useful for early diagnosis and precise treatment in patients presenting with heart failure with reduced ejection fraction. Histopathological and ultrastructural analyses can uncover potential treatments, and predict and improve prognosis by providing relevant information for understanding the pathogenesis and clinical evolution.

Objective:To analyze overall survival (OS), influential factors, and causes of death in patients with newly diagnosed non-transplant multiple myeloma (NDMM) at grassroots hospitals.Methods:The clinical data of 56 patients with NDMM admitted to the Department of Hematology, Wuwei People's Hospital from January 2018 to October 2022 were retrospectively analyzed. Using the Kaplan-Meier and Cox regression survival analysis models, univariate and multivariate analyses were performed to evaluate the factors affecting the OS of patients with NDMM.Results:The median OS of patients with NDMM was 27 months. Univariate analysis indicated that whether or not to receive chemotherapy was a risk factor affecting OS. Multivariate analysis revealed that age ( HR: 2.215, 95% CI 1.056-4.648, P < 0.05), renal dysfunction ( HR: 3.482, 95% CI 1.359-8.923, P < 0.05), and whether or not to receive chemotherapy ( HR: 0.83, 95% CI 0.021-0.331, P < 0.001) were all significant risk factors affecting OS (all P < 0.05). Conclusions:The median survival time of patients with NDMM is short. Age, renal dysfunction, and not receiving chemotherapy are unfavorable factors affecting OS. Pulmonary infection, renal failure, and disease progression are the main causes of death in patients with NDMM.
