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.

Intervention in chronically activated microglia-mediated neuroinflammation is a novel approach to treat Alzheimer's disease (AD). The low permeability of the blood‒brain barrier (BBB) and non-selective distribution in the brain severely restrict AD drugs' disease-modifying efficacy. Here, an immunosuppressant TREM2-lowing antisense oligonucleotides (ASOs) and resveratrol co-loaded cationic liposome is developed as an immune reprogramming nanomodulator modified by acid-cleavable BBB-targeting peptide and microglia-targeting peptide (Res@TcMNP/ASO) for AD management. Res@TcMNP/ASO can enter brain endothelial cells via D-T7 peptides. Then D-T7 undergoes an acid-responsive cleavage, facilitating the escape of Res@MNP/ASO from endo/lysosomes to cross the BBB. The detached Res@MNP/ASO specifically targets M1-phenotype microglia via exposed MG1 peptides to prompt the simultaneous delivery of two drugs into activated microglia. This nanomodulator can not only restore the immune function of microglia through TREM2-lowing ASO but also mitigate the immune stimulation to microglia caused by reactive oxygen species (ROS) through resveratrol, thereby synergistically inhibiting the chronic activation of microglia to alleviate neuroinflammation in AD. Our results indicate that this combination treatment can achieve significant behavioral and cognitive improvements in late APP/PS1 mice.

BACKGROUND: The purpose of this study was to evaluate the safety and efficacy of subsequent radiotherapy (RT) following first-line treatment with durvalumab plus chemotherapy in patients with extensive-stage small cell lung cancer (ES-SCLC). METHODS: A total of 122 patients with ES-SCLC from three hospitals during July 2019 to December 2021 were retrospectively analyzed. Inverse probability of treatment weighting (IPTW) analysis was performed to address potential confounding factors. The primary focus of our evaluation was to assess the impact of RT on progression-free survival (PFS) and overall survival (OS). RESULTS: After IPTW analysis, 49 patients received durvalumab plus platinum-etoposide (EP) chemotherapy followed by RT (Durva + EP + RT) and 72 patients received immunochemotherapy (Durva + EP). The median OS was 17.2 months vs . 12.3 months (hazard ratio [HR]: 0.38, 95% confidence interval [CI]: 0.17-0.85, P = 0.020), and the median PFS was 8.9 months vs . 5.9 months (HR: 0.56, 95% CI: 0.32-0.97, P = 0.030) in Durva + EP + RT and Durva + EP groups, respectively. Thoracic radiation therapy (TRT) resulted in longer OS (17.2 months vs . 14.7 months) and PFS (9.1 months vs . 7.2 months) compared to RT directed to other metastatic sites. Among patients with oligo-metastasis, RT also showed significant benefits, with a median OS of 17.4 months vs . 13.7 months and median PFS of 9.8 months vs . 5.9 months compared to no RT. Continuous durvalumab treatment beyond progression (TBP) prolonged OS compared to patients without TBP, in both the Durva + EP + RT (NA vs . 15.8 months, HR: 0.48, 95% CI: 0.14-1.63, P = 0.238) and Durva + EP groups (12.3 months vs . 4.3 months, HR: 0.29, 95% CI: 0.10-0.81, P = 0.018). Grade 3 or 4 adverse events occurred in 13 (26.5%) and 13 (18.1%) patients, respectively, in the two groups; pneumonitis was mostly low-grade. CONCLUSION Addition of RT after first-line immunochemotherapy significantly improved survival outcomes with manageable toxicity in ES-SCLC.

Objective:To observe the effects of RasGRP4 gene deletion on the structure and function of the retina in diabetic mice, and to explore the mechanism of RasGRP4 in diabetic retinopathy (DR) by transcriptome sequencing in conjunction with bioinformatics analysis. Methods:A total of 12 male C57BL/6J mice were divided into normal group, diabetic group (DM group), with 6 mice in each group. Six male RasGRP4 knockout mice were uesd as RasGRP4 knockout diabetic group (DM-KO group). Mice in the DM group and DM-KO group were fed with high-fat diet combined with intraperitoneal injection of streptozotocin to establish diabetic model and body weight and blood glucose were monitored regularly. Three months after modeling, optical coherence tomography was used to detect the retinal thickness and ganglion cell layer thickness. Electroretinography was used to detect the function of the retina in mice under dark-adapted conditions. Total RNA was extracted from the retinas of mice in DM group and DM-KO group, and transcriptomic sequencing was performed to screen differentially expressed genes (DEG). Core genes were screened using MCODE and Cytohubba plug-ins of Cytoscape v3.8.2 software. At the same time, the functional enrichment analysis of gene samples (GO) of the selected DEG was performed. The mRNA relative expression levels of interleukin-8, transforming growth factor-β (TGF-β), interferon-γ (IFN-γ), NOd-like receptor thermal protein domain protein 3 (NLRP3), Caspase-1 and IL-1β in each group were detected by real-time quantitative polymerase chain reaction. t test was used to compare the two groups. One-way analysis of variance was used to compare the three groups. Results:Compared with the DM group, there was no significant difference in blood glucose and body weight in the DM-KO group with the extension of high-fat diet ( t=0.12, 2.02, 0.22, 0.10, 0.59, 0.41, 1.35, 0.31, 1.12, 1.58, 1.47, 1.20, 1.24, 0.39, 0.66, 0.14; P>0.05). The retinal thickness and ganglion cell layer thickness of mice in the three groups were significantly reduced in the DM group compared with the normal group, while DM-KO was significantly increased compared with the DM group, and the differences were statistically significant ( F=30.43, 7.81; P<0.000 1, 0.01). Comparison of a-wave and b-wave amplitudes among the three groups showed that the DM group was significantly lower than the normal group, while the DM-KO was significantly higher than the DM group, and the differences were statistically significant ( F=16.46, 35.58; P<0.001, 0.000 1). Compared with the DM group, 184 differential genes (DEG) were screened in the DM-KO group, among which 39 up-regulated and 145 down-regulated genes were detected, respectively. The results of the MCODE plug-in analysis showed that Col1a2, Fbln1, Fbn1, Col6a3, Fmod, Ogn, Tgfb, Mfap4, Vcan, Nid2, and Col18a1 were core genes in the DEG. Cytohubba plug-in analysis showed that Col1a2, Mrc1, Cd47, Fbn1, Cybb, Cd163, Fbln1, Fmod, Adgre1, and Col6a3 were the core genes in DEG. The results of the GO functional enrichment analysis showed that DEG was mainly involved in hemoglobin complexes, MHC class Ⅱ protein complex, apical plasma membrane, inflammasome complex, immunological synapse, response to bacterium, inflammatory response, immune system processe, response to hypoxia, and cell adhesion were significantly enriched. Comparison of mRNA relative expression levels of IL-8, TGF-β, IFN-γ, NLRP3, Caspase-1 and IL-1β in the three groups showed that the DM group was significantly higher than the normal group, while the DM-KO was significantly lower than the DM group, with statistical significance ( F=12.43, 15.41, 70.09, 29.04, 11.79, 41.28; P<0.01). Conclusion:RasGRP4 deficiency plays a therapeutic role in the development of DR through inhibition of inflammatory factor secretion and NLRP 3 inflammasome pathway activation.

Diabetic retinopathy (DR) is one of the most common microvascular complications of diabetes, which seriously threatens the vision of patients. The pathogenesis of DR Is complex and involves many pathophysiological processes. At present, the treatment methods for DR Mainly include panretinal laser photocoagulation, vitrectomy and vitreous cavity injection, etc. However, each treatment method has certain limitations. In recent years, remarkable progress has been made in the field of drug treatment of DR, especially in anti-vascular endothelial growth factor drugs, anti-inflammatory drugs, anti-oxidative stress damage drugs, neuroprotective agents, gene therapy and stem cell therapy. These drugs not only improve the effectiveness of treatment, but also expand the range of treatment options. In addition, by carrying DR Treatment drugs on carriers such as nanoparticles, hydrogels and photosensitive materials, continuous and efficient release of drugs in the eye is achieved, thereby extending the time interval of administration and reducing the need for frequent treatment of patients. In the future, based on biomarker detection technology, it is expected to promote the development of personalized and precise treatment, which can develop more accurate treatment plans for patients and improve the efficacy.

Objective To investigate the specific molecular mechanism through which microRNA-4488(miR-4488)regulates the proliferation,migration and invasion capabilities of glioblastoma(GBM)by modula-ting the expression level of scratch family transcriptional repressor 1(SCRT1).Methods Quantitative real-time PCR(qPCR)was performed to measure the expression levels of miR-4488 and SCRT1 in astrocyte SVG cells and GBM U87MG cells.Transient transfection was used to introduce miR-4488 mimic nc(mimic control group),miR-4488 mimic(mimic group),miR-4488 inhibitor nc(inhibitor control group),and miR-4488 inhib-itor(inhibitor group)into U87MG cells,which were then divided into four groups accordingly.Lentiviral transfection was used to establish U87MG cell lines transfected with SCRT1 empty vector(control group)and SCRT1 overexpression plasmid(overexpression group).Bioinformatics analysis was performed to identify and validate the binding site sequence between miR-4488 and SCRT1,and the dual-luciferase reporter gene as-say was conducted to verify their targeting relationship.The EdU assay was employed to assess cell prolifera-tion capacity,while the Transwell assay was used to analyze differences in migratory and invasive capacities a-mong groups.Results Compared with SVG cells,miR-4488 expression was upregulated(P＜0.001)and SCRT1 expression was downregulated in U87MG cells(P＜0.001).After transient transfection with miR-4488 mimic,the expression of SCRT1 in the mimic group decreased compared to the mimic control group,with no significant change in proliferative capacity(P＞0.05),but enhanced migration and invasion abilities(P＜0.01 and P＜0.001,respectively).Conversely,after transfection with miR-4488 inhibitor,the expression of SCRT1 in the inhibitor group increased compared to the inhibitor control group,with no significant change in proliferative capacity(P＞0.05),but weakened migration and invasion abilities(P＜0.01 and P＜0.001,re-spectively).The dual-luciferase reporter gene assay confirmed that SCRT1 is a target of miR-4488 in U87MG cells.The SCRT1 overexpression group showed reduced migration and invasion abilities compared to the con-trol group(P＜0.01 and P＜0.001,respectively).Conclusion MiR-4488 can specifically regulate the expres-sion of SCRT1 to affect the migration and invasion characteristics of GBM.

Objective To investigate the relationship between the mean platelet volume(MPV)to platelet count(PLT)ratio(MPV/PLT),blood urea nitrogen(BUN)to lipoprotein a[Lp(a)]ratio[BUN/Lp(a)]and the prognosis of patients with acute exacerbation of chronic obstructive pulmonary disease(COPD).Methods A total of 106 patients with acute exacerbation of COPD admitted to the hospital from January 2021 to January 2024 were selected as the research objects.According to the prognosis,they were divided into sur-vival group(72 cases)and death group(34 cases).The results of routine laboratory tests,blood lipid and lipo-protein levels were compared between the two groups.Multivariate Logistic regression was used to analyze the influencing factors of death in patients with acute exacerbation of COPD.The receiver operating characteristic(ROC)curve was used to evaluate the predictive value of MPV/PLT and BUN/Lp(a)for the prognosis of pa-tients with acute exacerbation of COPD.Results Compared with the survival group,the invasive ventilation rate,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score,C reactive protein(CRP),white blood cell count(WBC),MPV,BUN,MPV/PLT and BUN/Lp(a)were significantly increased in the death group(P＜0.05).The non-invasive ventilation rate,lymphocyte count,PLT and Lp(a)levels were signifi-cantly decreased(P＜0.05).Multivariate Logistic regression analysis showed that APACHE Ⅱ score,CRP,WBC,lymphocyte count,MPV,PLT,MPV/PLT,BUN,Lp(a)and BUN/Lp(a)were the influencing factors of death in patients with acute exacerbation of COPD(P＜0.05).ROC curve results showed that the sensitivity and specificity of MPV/PLT combined with BUN/Lp(a)for predicting the prognosis of patients with acute exacerbation of COPD were 88.2％and 84.7％,respectively,and the area under curve was 0.887.Conclusion MPV/PLT and BUN/Lp(a)are closely related to the prognosis of patients with acute exacerbation of COPD.The combination of MPV/PLT and BUN/Lp(a)has a high predictive value for the prognosis of patients.

Objective:To explore the medication thinking and compatibility rules of TCM for the treatment of diabetic nephropathy (DN).Methods:Relevant journal literature of TCM for the treatment of DN was retrieved from CNKI, Wanfang Data, VIP, and CBM from January 1, 2000 to December 31, 2023, and a database was established through Excel 2016. Python 3.10 and the ancient and modern medical record cloud platform 2.3.5 were used to conduct Latent Dirichlet Allocation (LDA) topic modeling and association rule analysis to explore the thinking and compatibility rules of TCM prescriptions in the literature.Results:A total of 474 articles were included in the study, including 474 prescriptions, involving 260 kinds of Chinese materia medica, of which 40 kinds of Chinese materia medica with a frequency of ≥ 30, mainly Astragali Radix, Salviae Miltiorrhizae Radix et Rhizoma, Dioscoreae Rhizoma, Poria, and Corni Fructus, etc. The LDA topic model identified three groups of prescriptions, including four classic prescriptions: Liuwei Dihuang Pills, Taohong Siwu Decoction, Erzhi Pills, and Wuling Powder. The commonly used drug combinations extracted by association rules were: Rhizoma Alismatis - Poria, Cortex Moutan Radicis-Fructus Corni and Cortex Moutan Radicis - Rhizoma Dioscoreae.Conclusions:The main therapeutic principle of TCM in treating DN is to nourish the yin and tonify the kidney, supplemented by drugs that promoting blood circulation for removing blood stasis as well as promoting urination and draining dampness. In clinical application, modern doctors tend to use classic prescriptions such as Liuwei Dihuang Pills, Erzhi Pills, Taohong Siwu Decoction, and Wuling Powder as the basis, and modify them according to the specific conditions of patients. The LDA topic model can extract valuable prescription information from a large number of modern TCM literature, providing new perspectives and ideas for the study of clinical medication rules in TCM.
