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 explore the feasibility, safety, and short-term efficacy of a total pelvic floor resection procedure as a component of combined resection of pelvic organs for locally advanced or locally recurrent rectal cancer.Methods:This was a descriptive case series. Relevant clinical data of patients with locally advanced or locally recurrent rectal cancer without extrapelvic metastasis or with only oligometastasis who had undergone combined pelvic organ resection with resection of the entire pelvic floor in the Department of Anorectal Surgery of the Second Affiliated Hospital of Naval Medical University from 1 January 2023 to 30 June 2024 were collected from a Chinese database of combined pelvic organ resection for rectal cancer. The study cohort comprised 143 patients, 74 of whom were male (51.7%) and 69 were female (48.3%); their ages averaged 54 (range: 31–75) years; 57 of the patients (39.9%) had locally advanced rectal cancer and 86 (60.1%) locally recurrent rectal cancer. In our institution, the pelvic floor is categorized into two anatomical layers: the levator ani/presacral anterior tissue, and the bone/ligament/pelvic floor soft tissue. The entire pelvic floor was resected en bloc after making incisions on both sides of the pelvic floor, followed by presacral sacral dissection, and abdominoperineal dissection of the anterior side of the pelvic floor. The main factors studied were related to the following: (1) surgical conditions, comprising the scope of surgical resection, operation time, intraoperative blood loss, tissue reconstruction; (2) postoperative recovery, comprising time to recovery of intestinal function, time to removal of drainage tubes, and time to healing of the empty pelvic cavity; and (3) postoperative complications, classified according to the international Clavien-Dindo classification. Results:Combined pelvic organ resection with entire pelvic floor resection was successfully completed in all patients. The operation time was 480 (390 to 1,020) minutes, intraoperative blood loss 800 (50 to 3,500) mL, and volume of blood transfused intraoperatively 1, 000 (400 to 7, 400). R0 resection was achieved in 116 cases (81.1%) and R1 resection in 27 (18.9%). The first layer of the pelvic floor wall (levator ani/sacral anterior tissue) was resected in 79 cases (55.2%) and the second layer of the pelvic floor wall (bone/ligament/pelvic floor soft tissue) in 64 (44.8%). The procedure was completed in the lithotomy position in 114 cases (79.7%) were and in the lithotomy + prone jackknife position in 29 (20.3%). The pelvic floor was reconstructed with mesh in 140 cases (97.7%) and with mesh plus pedicled omental flaps in 92 cases (64.3%). The urinary tract was reconstructed in 92 cases (64.3%). The time to recovery of intestinal function was 3.6 (2.0 to 7.0) days, to removal of drainage tubes 29.4 (24.0 to 54.0) days, and to healing of the empty pelvic cavity 36.2 (27.0 to 56.0) days. Twenty-three patients (16.1%) had Grade I - II complications and 36 (25.2%) Grade IIIa - IV complications. The median duration of follow-up was 15.5 (0.5 to 30.0) months. Six of the patients (4.2%) died, including two (1.4%) who died within 30 days after surgery.Conclusions:Pelvic floor en bloc resection has a high R0 resection rate and is a safe and feasible procedure for pelvic organ resection surgeries in patients with locally advanced or locally recurrent rectal cancer.

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.

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.

[Objective] To explore the diagnosis and treatment experience of tension hydrocele. [Methods] The clinical data of 2 patients with tension hydrocele treated in our hospital were retrospectively analyzed.Relevant literature was retrieved to analyze the clinical characteristics of this disease. [Results] Case 1 was diagnosed due to swelling and pain of the left scrotum after trauma for more than one month, which worsened for one day.Physical examination showed high tension in the left scrotum and positive light transmission test.Ultrasound examination revealed that the blood flow signal in the left testis disappeared.Emergency left scrotal exploration and hydrocelectomy were performed.There was no sign of testis torsion during the operation.Case 2 was diagnosed mainly due to hydrocele of the right testis for 1 year, which worsened for 1 week and complicated with testis distension and pain.Physical examination showed high tension in the right scrotum and positive light transmission test.Ultrasound examination revealed that the blood flow signal in the right testis decreased.After 40ml of fluid was extracted under ultrasound monitoring, the blood flow signal in the right testis recovered.Hydrocelectomy was performed the next day.During the follow-up of 8 months, there was no recurrence of hydrocele.A search of domestic and foreign literature showed that there were no reports in domestic literature, while a total of 11 cases were reported in foreign literature. [Conclusion] Tension hydrocele of the testis is a rare emergency of the scrotum.Surgery or decompression should be performed as soon as possible to restore testicular blood supply, and hydrocelectomy should be performed simultaneously or in stages to prevent recurrence.
