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.

OBJECTIVES: To investigate the active ingredients in Hedyotis diffusa-Scutellaria barbata D. Don and the main biological processes and signaling pathways mediating their inhibitory effect on primary hepatocellular carcinoma (HCC). METHODS: The core intersecting genes of HCC and the two drugs were screened from TCMSP, Uniport, Genecards, and String databases using Cytoscape software, and GO and KEGG enrichment analyses of the intersecting genes were conducted. Molecular docking between the active ingredients of the drugs and the core genes was carried out using Pubcham, RCSB and Autoduckto to identify the active ingredients with the highest binding energy, whose inhibitory effect on HepG2 cells was verifies using CCK-8 assay, flow cytometry and Western blotting. RESULTS: TP53 and ESR1 were identified as the core genes of HCC and the two drugs. GO and KEGG analyses showed that the two genes were mainly involved in regulation of apoptotic signaling pathway, cell population proliferation, methane raft, and protein kinase activity, and participated in the signaling pathways of apoptosis, proteoglycans in cancer, PI3K Akt signaling pathway, and hepatitis B. Molecular docking studies showed that the active ingredients of the drugs could be docked with TP53 and ESR1 genes under natural conditions, and ursolic acid had the highest binding energy to ESR1 (-4.98 kcal/mol). The results of CCK-8 assay, flow cytometry and Western blotting all demonstrated significant inhibitory effect of ursolic acid on HepG2 cells. CONCLUSIONS The inhibitory effect of Hedyotis diffusa-scutellariae barbatae on HCC is mediated by multiple active ingredients in the two drugs.

A domestically produced self-expanding transcatheter aortic valve controllable bending delivery system(VitaFlow? Ⅲcontrollable bending retrievable delivery system)was first used to perform transcatheter aortic valve replacement(TAVR)in a symptomatic severe aortic valve stenosis patient with severe heart failure and high risk of surgery in China on September 22,2023.The patient successfully completed TAVR under general anesthesia,with good valve position and function after the operation.Before discharge and at one month of follow-up,the patient's symptoms and degree of heart failure were significantly improved.The follow-up results of this case showed that the VitaFlow? Ⅲ controllable bending retrievable delivery system for TAVR is safe and feasible,and future prospective,multicenter clinical trials are expected to evaluate its efficacy.

Objective To establish a trimethyltin chloride (TMT) -induced learning and memory impairment model in rats, and to investigate the protective effects and potential mechanisms of ferulic acid. Methods Specific pathogen-free male SD rats were randomly divided into control group, TMT intoxication group, fluoxetine group and 25, 50, 100 mg/kg ferulic acid group. The rats in the last five groups were injected with a dose of 8 mg/kg body weight TMT solution, and the rats in control group were injected with the same volume of 0.9% sodium chloride solution. After 24 hours of TMT injection, the rats in fluoxetine group were treated 10 mg/kg body weight of fluoxetine, the rats in the three ferulic acid groups were treated with ferulic acid at doses of 25, 50, and 100 mg/kg body weight, respectively. The rats in the control group and TMT intoxication group were treated with the same volume of 0.9% sodium chloride solution, once per day for continuous gavage for 28 days. Morris water maze experiment and light-dark box test were used to assess the learning and memory abilities of the rats. The mRNA and protein expressions of nuclear transcription factor-κB (NF-κB), tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in the rat hippocampus were detected by real-time quantitative polymerase chain reaction and Western blot. The levels of reactive oxygen species (ROS) and malondialdehyde (MDA) and the activities of superoxide dismutase (SOD) and catalase (CAT) in the rat hippocampus were detected by enzyme-linked immunosorbent assay. Results Compared with the control group, rats of TMT intoxication group on day four had prolonged escape latency (P<0.05), fewer platform crossing (P<0.05), shorter time spent in the target quadrant and shorter latency to enter the dark compartment (all P<0.05). The mRNA and protein relative expression of NF-κB, TNF-α and IL-1β increased (all P<0.05), ROS and MDA levels increased (all P<0.05), SOD and CAT activities decreased (all P<0.05) in the rat hippocampus of TMT intoxication group on day four compared with that of the control group. Except for the terms of escape latency and target quadrant period of the rats in the 25 mg/kg ferulic acid group, rats in three ferulic acid groups on day four had lower escape latency (all P<0.05), more platform crossing (all P<0.05), longer period in the target quadrant and longer latency to enter the dark compartment (all P<0.05), compared with TMT intoxication group. Except for the relative protein expression of TNF-α in the rats of 50 mg/kg ferulic acid group, the mRNA and protein expression of NF-κB, TNF-α and IL-1β decreased (all P<0.05), ROS and MDA levels were reduced (all P<0.05), and the activities of SOD and CAT increased (all P<0.05) in the hippocampus of rats of 50 and 100 mg/kg ferulic acid groups compared with TMT intoxication group. Conclusion Ferulic acid can reverse TMT-induced learning and memory impairment in rats, and its mechanism of action may be related to alleviating oxidative stress damage and excessive inflammatory response in rat hippocampus.

OBJECTIVE To investigate the mechanisms by which Pinggan Yishen Decoction(PGYSD)contributes to alleviating target organ damage in spontaneously hypertensive rats.METHODS The chemical components of PGYSD were determined by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS)and were analyzed by target a-nalysis and functional enrichment combined with network pharmacology methods to predict the potential mechanism of PGYSD in trea-ting hypertension and its target organ damage.Spontaneously hypertensive rats were randomly divided into the model group,low-dose PGYSD group(2 g·kg-1),high-dose PGYSD group(5 g·kg-1),and valsartan group(7.2 mg·kg-1),with 6 rats in each group.Wistar-Kyoto rats were used as the control group,and the control group and the model group were gavaged with normal saline for 8 consecutive weeks.HE and Masson staining were used to observe the pathological damage and fibrosis degree of rat heart and tho-racic aorta.Immunohistochemical staining and Western blot were used to detect the expression level of EGFR in the heart,liver and kidney of rats.Immunofluorescence staining was used to detect the co-localization of EGFR and EEA1 in the heart,liver and kidney of rats.RESULTS Twenty-six components of PGYSD were detected by UPLC-Q-TOF/MS.Network pharmacology revealed that EG-FR,PIK3R1 and EP300 may be key therapeutic targets of action of PGYSD for the treatment of hypertension and its target organ dam-age,and that the treatment of hypertension and its target organ damage by PGYSD may be closely related to EGFR tyrosine kinase in-hibitor resistance,lipids and atherosclerosis and HIF-1 signaling pathway.The high-dose group of PGYSD significantly reduced sys-tolic blood pressure and mean blood pressure in rats(P<0.05,P<0.01),attenuated pathological damage and fibrosis in the heart and thoracic aorta(P<0.01,P<0.001),significantly reduced the expression level of EGFR in the liver and kidney of rats(P<0.01),and treated fibrosis in liver and kidney,reduced the co-localization of EGFR and EEA1 in the kidney of rats(P<0.001),attenuated fibro-sis in kidney.CONCLUSION The paper integrates UPLC-Q-TOF/MS,network pharmacology and spontaneously hypertensive rat model and preliminarily explores the effect mechanism of PGYSD in the treatment of hypertension and its target organ damage,provi-ding a scientific basis for further mechanism research and clinical application of PGYSD in the treatment of hypertension.

Fingertip injuries often involve the loss of skin, soft tissue, and sometimes even phalange, seriously affecting the patient's hand function and appearance. Therefore, fingertip reconstruction requires both functional recovery and aesthetics. And how to better restore fingertip defect has become an issue that hand surgeons should continue to explore. In recent years, free flaps have made remarkable progress in the field of fingertip repair, and free flaps such as radial artery superficial palmar branch free flap, free thenar flap and free toe flap provide a variety of effective methods to solve the problem. By referring to the literatures on free flap in fingertip repair, this paper summarises the application status and research progress of free flap in fingertip defect reconstruction, providing a reference for personalised treatment of patients with fingertip defect.

Objective To investigate the guiding value of computed tomography angiography(CTA)in the treatment of vascular embolization in patients with emergency pelvic fracture hemorrhage.Methods From June 2019 to June 2023,67 patients with emergency pelvic fracture hemorrhage were selected from General Hospital Medical Communities of Shaoxing Second Hospital.All patients underwent CTA and digital subtraction angiography(DSA),and the application value of CTA was evaluated using the results of DSA as the gold standard.Results CTA examination showed that 66 patients had vascular injury,bleeding or injury of 167 vessels.DSA examination showed that 66 patients had vascular injury,bleeding or injury of 186 vessels.The detection rate of CTA for positive cases was 97.0%,and the detection rate for vascular injury was 82.8%.The positive predictive value of CTA was 92.2%,the negative predictive value was 97.1%,the sensitivity was 82.8%,and the specificity was 98.8%.Conclusion The diagnostic results of CTA examination for emergency pelvic fracture hemorrhage are highly consistent with DSA,which can provide an important reference for the formulation of treatment plans for patients.

Objective To investigate the effects of long-term exposure to three new types of light emitting diode (LED) sources on the behavior, learning, and memory of rats. Methods A total of 160 specific pathogen-free SD rats were divided into eight groups as followed, trichromatic fluorescent lamps color temperature control group, violet-chip full-spectrum white LED group, blue-chip white LED group, and blue-chip full-spectrum white LED group based on the light sources types, with color temperature of 4 000 K and 6 500 K groups in each group using the 4×2 factorial design. There were 20 rats in each group, with half of the rats were males and half females. Rats were exposed to artificial lighting, and the illumination was set at 750 lx. The rats in each group were exposed to different lighting environments for 12 hours per day for 24 weeks. The open-field and step-down tests were conducted in rats after 24 weeks exposure, followed by sacrifice of rats and measurement of organ coefficients. Differences in body weight, organ coefficients, and neurobehavioral indexes of rats in different groups were compared. Results The spleen coefficient of female rats decreased in blue-chip white LED of 6 500 K color temperature group, and the liver coefficient of male rats decreased in the violet-chip full-spectrum white LED of 4 000 K color temperature, blue-chip full-spectrum white LED of 4 000 K color temperature, and blue-chip full-spectrum white LED of 6 500 K color temperature groups, compared with the same-sex rats in trichromatic fluorescent lamps with same-color temperature control group (all P<0.05). The result of different types of light sources compared in the open-field test showed that the index of total distance and movement speed of female rats in the blue-chip full-spectrum white LED group were lower than those in the other three groups, and the time cost to the central area was longer than that in the blue-chip white LED group and the violet-chip full-spectrum white LED group (all P<0.05). The total distance and movement speed of male rats in the blue-chip full-spectrum white LED group were longer or higher than those in the violet-chip full-spectrum white LED group (all P<0.05). Based on the comparison of color temperature, the time and total distance of male rats in 6 500 K color temperature group were lower than that in the 4 000 K color temperature group (both P<0.05). In the step-down test, both male and female rats in the blue-chip full-spectrum white LED group made more errors compared with other three groups with the same gender (all P<0.05). Conclusion Based on the experimental conditions of this study, the blue-chip full-spectrum white light LED affects behavior, learning and memory of the rats, and trichromatic fluorescent lamp has the lowest effect on neurobehavior. The color temperature also affects behavior of the rats, and high color temperature has higher risk.

Objective:To investigate the protective effects of an anti-inflammatory mixture on acute lung injury (ALI) induced by sepsis in rats, as well as its possible mechanisms.Methods:A total of 40 Sprague-Dawley (SD) rats were randomly divided into the sham group, septic ALI model group (model group), 3-methyladenine (3-MA) control group, and anti-inflammatory mixture pretreatment group, with 10 rats in each group. Cecal ligation and perforation (CLP) was performed to reproduce a septic ALI model. The rats in the sham group only underwent opening and closing the abdomen without perforation and ligation. Both groups were given saline gavage and intraperitoneal injection for 3 consecutive days before surgery. The 3-MA control group was given intraperitoneal injection of saline and autophagy inhibitor 3-MA 15 mg/kg for 3 consecutive days before modeling. The anti-inflammatory mixture pretreatment group was given 8.8 mL/kg of anti-inflammatory mixture by gavage [the composition of anti-inflammatory mixture: rhubarb 15 g (after the next), coptis chinensis 15 g, baical skullcap root 12 g, magnoliae cortex 12 g, dahurian patrinia herb 30 g] and saline intraperitoneal injection for 3 consecutive days before modeling. The rats in each group were anesthetized 24 hours after surgery and died due to abdominal aortic blood collection. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of serum inflammatory cytokines interleukins (IL-1β and IL-6). Lung tissue was taken and then the bronchoalveolar lavage fluid (BALF) was collected, and the levels of IL-1β and IL-6 were detected by ELISA. Lung wet/dry weight (W/D) ratio was measured. After hematoxylin-eosin (HE) staining, the histopathological changes of the lungs were observed under light microscopy. Western blotting was used to detect the expression of autophagy markers microtubule-associated protein 1 light chain 3-Ⅱ/Ⅰ (LC3-Ⅱ/Ⅰ) and Beclin-1 protein in lung tissue. Autophagosomes in lung tissue were observed with transmission electron microscopy.Results:Compared with the sham group, the rats in the model group exhibited severe destruction of lung tissue structure, with significant infiltration of inflammatory cells, the lung W/D ratio and the levels of IL-1β and IL-6 in serum and BALF were significantly increased, the expressions of LC3-Ⅱ/Ⅰ and Beclin-1 protein were down-regulated, the autophagosomes were more. The rats in the 3-MA control group exhibited more severe lung tissue injury as compared with the model group, the lung W/D ratio and the levels of inflammatory cytokines in serum and BALF were further increased, the expressions of LC3-Ⅱ/Ⅰ and Beclin-1 protein still showed a decrease tendency as compared with the sham group, and the autophagosomes were less than that in the model group. Compared with the model group, the anti-inflammatory mixture pretreatment group showed milder lung tissue injury with a minimal amount of inflammatory cell infiltration, the lung W/D ratio was significantly reduced (7.07±1.02 vs. 11.33±1.85, P < 0.05), the levels of IL-1β and IL-6 in both serum and BALF were significantly decreased [IL-1β (ng/L): 26.04±3.86 vs. 40.83±5.46 in serum, 17.75±2.02 vs. 26.86±4.32 in BALF; IL-6 (ng/L): 91.28±10.15 vs. 129.44±13.05 in serum, 76.06±7.51 vs. 120.91±7.47 in BALF, all P < 0.05], and the ratio of LC3-Ⅱ/Ⅰ and Beclin-1 protein expression were significantly increased [LC3-Ⅱ/Ⅰ ratio: 1.23±0.02 vs. 0.60±0.02, Beclin-1 protein (Beclin-1/GAPDH): 2.37±0.33 vs. 0.62±0.05, both P < 0.05]. Furthermore, an increase in the number of autophagosomes was observed. Conclusion:The anti-inflammatory mixture improves lung injury in rats with sepsis induced by CLP and reduce inflammation levels, potentially through upregulation of Beclin-1-mediated autophagy.
