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.

Objective To explore the effect of PCSK9 inhibitor combined with atorvastatin on carotid atherosclerosis and its anti-inflammatory effect in patients with hypertension complicated with type 2 diabetes mellitus.Methods A total of 100 patients with hypertension complicated with type 2 diabetes mellitus who were treated in Nanchang Third Hospital from October 2022 to August 2023 were selected as the research subjects.They were divided into the control group and the study group by the random number table method,with 50 cases in each group.Both groups of patients received conventional antihypertensive,hypoglycemic,and antiplatelet therapy.The control group took 20 mg of atorvastatin calcium tablets orally,once a night.On the basis of the control group,the study group was additionally given 150 mg of evolocumab injection(a PCSK9 inhibitor)by subcutaneous injection,once every two weeks.Both groups of patients were followed up for 24 weeks.The levels of blood lipids,blood glucose,inflammatory cytokines,carotid intima-media thickness(IMT),atherosclerotic plaque score and adverse reactions of the patients in the two groups before and after treatment were detected and compared.Results The levels of TC,TG and LDL-C in the study group after treatment were lower than those before treatment and those in the control group at the same period,and the differences were statistically significant(P＜0.05).The levels of IL-1,IL-6,TNF-α,hs-CRP,as well as the ca-rotid IMT and atherosclerotic plaque score in the study group after treatment were lower than those before treatment and those in the control group at the same period,and the differences were statistically significant(P＜O.05).During the treatment period,there was no significant difference in the occurrence of adverse reac-tions between the two groups(P＞0.05).Conclusion The combination of PCSK9 inhibitor and atorvastatin can effectively regulate the blood lipid levels of patients with hypertension complicated and type 2 diabetes mellitus,alleviate the inflammatory response,and improve the degree of carotid atherosclerosis in these pa-tients.

OBJECTIVE To evaluate the clinical value of dose-escalated postoperative radiotherapy(PORT)in improving local control and survival outcomes for head and neck adenoid cystic carcinoma(ACC)patients.METHODS This retrospective study analyzed 336 ACC patients treated with surgery plus PORT at Beijing Tongren Hospital from January 2015 to January 2021.Cohort stratification compared high-dose(>60 Gy,n=146)and conventional-dose(≤60 Gy,n=190)regimens.Survival analysis employed Kaplan-Meier estimates with log-rank testing,complemented by multivariate Cox regression for risk adjustment.RESULTS The cohort demonstrated 39.29%(132/336)cumulative local failure rate.The overall survival rates at 1,3,and 5 years after surgery were 98.81%,94.05%,and 90.48%,respectively.Dose-response relationships revealed:1.Significantly reduced local recurrence with high-dose PORT(28.08%vs.47.89%,P<0.001),corresponding to 41.37%lower recurrence risk(a HR=0.59,95%CI=0.38-0.91;P=0.041);2.Superior progression-free survival in the high-dose group(3-year:86.99%vs.76.32%;5-year:82.19%vs.66.32%,all P<0.05);3.Comparable overall survival between groups(median OS:200 vs.160 months,P=0.292).CONCLUSION Dose escalation beyond 60 Gy significantly enhances locoregional control and progression-free survival in head and neck ACC without conferring overall survival advantage,likely reflecting the disease's characteristic indolent metastatic progression.These results establish>60 Gy as an optimal dose threshold for PORT in high-risk ACC management.

Objective: To establish and identify hepatocyte-specific transmembrane protein 121 ( Tmem121 ) knockout mice． Methods: The hepatocyte-specific Tmem121 knockout mice ( Tmem121flox / flox / Cre，Tmem121ΔHep) were obtained by crossbreeding of Tmem121flox / + / Cre and Tmem121flox / flox mice，which were generated using the CRISPR / Cas9 and Cre / Loxp systems．The genotype was verified by PCR using genomic DNA extracted from mouse tails as template．The growth，reproduction and organ development of both control and knockout mice were ob- served and analyzed．PCR and Western blot methods were performed to assess the knockout efficiency of Tmem121 in mouse primary hepatocytes．CellMaskTM Deep Red plasma membrane staining was employed to compare the mor- phological differences in primary hepatocytes between control and knockout mice． Results: Tmem121flox / flox / Cre mice were successfully obtained according to genotype identification analysis，and there were no significant differ- ences between control and knockout mice in body mass，reproductive ability，growth and development of liver．The specific knockout of Tmem121 gene in primary hepatocytes did not significantly affect the morphological structure or pathological characteristics of liver tissue．However，compared to the control group，the levels of Tmem121 mRNA and protein in the primary hepatocytes of the knockout group were significantly reduced ( P ＜0. 01) ．CellMaskTM Deep Red plasma membrane staining indicated that the proportion of binucleated hepatocytes in Tmem121-deficient mice significantly increased ( P＜0. 05) ，while the cell area was significantly reduced ( P＜0. 001) ． Conclusion Hepatocyte-specific Tmem121 knockout mice are successfully constructed，which provides an animal model for further exploration of the function and mechanism of Tmem121 gene in liver diseases．

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.

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 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.
