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.

BACKGROUND:Calcaneal defects are common in clinical practice.It is difficult for surgeons to evaluate the effect of calcaneal reconstruction due to the complex anatomical structure and motor function of the heel.Finite element analysis has become an effective method for biomechanical behavior simulation and numerical analysis. OBJECTIVE:To compare the clinical effect and biomechanical characteristics of total calcaneal reconstruction with the Ⅱ-shaped and V-shaped fibular flap. METHODS:CT images of one left foot of a healthy 50-year-old male were acquired.Mimics software was used to obtain the preliminary three-dimensional model.Geomagic software was used to trim and curve the model.The model was imported into Solidworks software to simulate calcaneal reconstruction and complete the pre-processing of finite element calculation.Finally,Ansys software was used to solve the problem.The simulation results were compared with previous literature results to verify the effectiveness of the model.The surgical effect and biomechanical characteristics of the foot in different gait phases based on the simulated stress results were analyzed. RESULTS AND CONCLUSION:(1)Both Ⅱ-shaped and V-shaped fibular flaps could be used to reconstruct completely missing calcaneus,which could restore the length,width and height of normal calcaneus,and fill up the missing calcaneus bone.(2)Compared with the normal calcaneus,both configurations of fibular flaps showed a tendency for over-concentration of stress after loading.The normal calcaneus stress was mostly concentrated around the calcaneus nodule,the subtalar process and the calcaneus groove,while the stress of the two fibular flaps was mostly concentrated at the junction between the bone flap with the talus and cuboid bones.(3)The maximum stress of calcaneus was different between the two models and normal calcaneus under different simulation conditions,with statistically significant differences(P＜0.05).Compared with the V-shaped fibular flaps,Ⅱ-shaped fibular flaps had less force change in different gaits and were closer to the normal calcaneus.The V-shaped fibular flap bore excessive stress during the period of push-off,and the grafted bone material may yield under this condition and have the risk of fractures.

Objective:To evaluate the disinfection effect of high-energy pulse ultraviolet disinfection equipment in medical institution settings.Methods:The disinfection effect was evaluated through field tests and laboratory tests. Among them, 135 high-frequency contact points were selected from nine departments in the field test. Samples were collected before and after disinfection, and the disinfection effects of 75% alcohol wipes wiping disinfection, high-energy pulse ultraviolet disinfection robot disinfection and high-energy pulse ultraviolet handheld disinfection instrument were compared. In the laboratory test, 30 infected areas of the simulated test table were exposed to vertical ultraviolet irradiation and the bacterial-killing rate before and after disinfection was calculated.Results:In the field test, the bacteria-killing rates of 75% alcohol wipes, high-energy pulse ultraviolet disinfection robot and high-energy pulse ultraviolet handheld disinfection instrument were 94.99%, 91.53% and 95.94%, respectively, and the difference was statistically significant. The disinfection effect of the high-energy pulse ultraviolet handheld disinfection instrument was better than that of the high-energy pulse ultraviolet disinfection robot ( P values <0.05). In the laboratory test, the killing log value of Staphylococcus aureus and Escherichia coli on the carrier were both greater than 3.00. In the simulated field test, the killing log value of Staphylococcus aureus on the surface samples were 4.99. Conclusion:Both the high-energy pulse ultraviolet handheld disinfection instrument and the high-energy pulse ultraviolet disinfection robot have good disinfection effects, which are similar to the disinfection effects of conventional 75% alcohol wipes.

Colorectal tumors often create an immunosuppressive microenvironment that prevents them from responding to immunotherapy.Cannabidiol(CBD)is a non-psychoactive natural active ingredient from the cannabis plant that has various pharmacological effects,including neuroprotective,antiemetic,anti-inflammatory,and antineoplastic activities.This study aimed to elucidate the specific anticancer mechanism of CBD by single-cell RNA sequencing(scRNA-seq)and single-cell ATAC sequencing(scATAC-seq)technologies.Here,we report that CBD inhibits colorectal cancer progression by modulating the suppressive tumor microenvironment(TME).Our single-cell transcriptome and ATAC sequencing results showed that CBD suppressed M2-like macrophages and promoted M1-like macrophages in tumors both in strength and quantity.Furthermore,CBD significantly enhanced the interaction between M1-like macrophages and tumor cells and restored the intrinsic anti-tumor properties of macrophages,thereby preventing tumor progression.Mechanistically,CBD altered the metabolic pattern of macro-phages and related anti-tumor signaling pathways.We found that CBD inhibited the alternative acti-vation of macrophages and shifted the metabolic process from oxidative phosphorylation and fatty acid oxidation to glycolysis by inhibiting the phosphatidylinositol 3-kinase-protein kinase B signaling pathway and related downstream target genes.Furthermore,CBD-mediated macrophage plasticity enhanced the response to anti-programmed cell death protein-1(PD-1)immunotherapy in xenografted mice.Taken together,we provide new insights into the anti-tumor effects of CBD.

Objective:To investigate the value of surgical classification and pelvic floor reconstruction in pelvic exenteration for locally recurrent or locally advanced rectal cancer. Methods:A retrospective descriptive study method was used.Perioperative data were collected from 67 consecutive patients with locally advanced or locally recurrent rectal cancer who underwent pelvic exenteration at the Department of Anorectal Surgery,the Second Affiliated Hospital of Navy Military Medical University between November 2021 and November 2022 through the Chinese Combined Pelvic Exenteration Case Database for rectal cancer.The surgical range was divided into two categories:mainly localized in the pelvic cavity(48 cases)and combined with resection of the main tissue of the pelvic wall(1 9 cases).Outcome indexes included:(1)preoperative general data of patients;(2)intraoperative conditions;(3)postoperative recovery and complications(postoperative complications were evaluated by international Clavien-Dindo classification);(4)follow-up(outpatient and telephone follow-up were used to understand the postoperative survival,tumor recurrence and metastasis of patients,and the follow-up time was up to February 28,2023 or the case died).Measurement data are expressed by median(range),and enumeration data are expressed by example(％). Results:In the pelvic resection group,the median age of 48 patients was 57.5 years(range:31-82 years);29 were males and 19 were females;26 of them had locally advanced rectal cancer and 22 had locally recurrent rectal cancer;39 had a history of chemotherapy,immunotherapy or targeted therapy,and 26 had a history of radiotherapy;the median operation time was 425 min(range:240-1 020 min);the median intraoperative blood loss was 500 mL(range:200-4 000 mL);the median time to recovery of intestinal function was 3 d(range:1-9 d);the median recovery time of empty pelvis syndrome was 25.3 d(range:5-105 d);43 patients had postoperative complications＜grade Ⅲ,and of the 5 patients with ≥ grade Ⅲcomplications,2 died of multiple organ failure 7 d after operation,2 patients had surgical hemostasis for massive hemorrhage of pelvic floor wounds after operation,and 1 patient recovered from postoperative respiratory failure after rescue.In the combined pelvic wall resection group,the median age of 1 9 patients was 54.5 years(range:43-76 years);9 were males and 10 were females;4 patients had locally advanced rectal cancer and 15 patients had locally recurrent rectal cancer,all of whom had a history of chemotherapy,immunotherapy or targeted therapy,and 1 5 patients had a history of radiotherapy;the median operation time was 580 min(range:360-960 min);the median intraoperative blood loss was 1 600 mL(range:400-4 000 mL);the median intestinal function recovery time was 3 d(range:2-7 d);the median empty pelvis syndrome recovery time was 62.3 d(range:7-120 d);15 patients had postoperative complications＜grade Ⅲ,and of the 4 patients with grade ≥ Ⅲ,3 patients had surgical hemostatis for postoperative pelvic floor wound bleeding and 1 patient recovered after the second operation for intestinal obstruction.As of February 28,2023 or death,67 patients were followed up for a median of 7.5 months(range:3-1 5 months),and 3 patients died 3-8 months after operation due to rapid tumor progression,severe urinary tract infection,and sudden heart disease during the follow-up period.The remaining 62 cases survived. Conclusion:The surgical classification has guiding significance for preoperative surgical planning in patients with locally advanced or locally recurrent rectal cancer who undergo combined pelvic exenteration,and the method of pelvic floor reconstruction based on biological mesh is safe and feasible in combined pelvic exenteration for locally advanced or locally recurrent rectal cancer.

Objective:To examine the effectiveness of thin struct bare stents for the treatment of spontaneous isolated dissection of the superior mesenteric artery (SIDSMA).Methods:The data of 32 patients admitted to First Hospital of Jiaxing (20 cases) and Jinling Hospital (12 cases) with SIDSMA from January 2016 to January 2021 were retrospectively analyzed. There were 27 males and 5 females, aging (54.8±9.4) years (range: 36 to 75 years). All patients were treated with thin struct bare stents. Controllable spring coils were used to fulfill the false lumen in 2 cases. Symptoms, vascular remodeling pattern at the SIDSMA lesion, and patency of the stents were observed during follow-up.Results:The surgical success rate was 100%. According to the length of the lesions and stents, the number of stents implanted was 1 in 17 cases, 2 in 11 cases and 3 in 4 cases. The angiography showed that blood flow in the stent was smooth. The numerical rating scale for abdominal pain decreased from 6.1±1.5 (range: 4 to 10) preoperatively to 1.0 (1.0) (range: 0 to 3) 1 hour postoperatively ( W=528, P<0.01). The compression rate of the true lumen of the superior mesenteric artery decreased from (92.3±6.7)% (range: 25% to 94%) preoperatively to 0.8 (1.2)% (range: 0 to 3.2%) 1 month postoperatively ( W=528, P<0.01). The primary patency rate of CT angiography at 1 month postoperatively was 100%. The vascular remodeling rate was (92.3±6.7)% (range: 80% to 100%). All patients were followed for (46.3±17.0) months (range: 24 to 76 months). The cumulative patency rates in 1, 2 and 5 years were all 100%. Conclusion:The use of thin struct bare stents for SIDSMA could obtained the expected safety and efficacy.
