BACKGROUND:The repair process of myocardial injury involves complex cellular and molecular mechanisms,especially mitochondrial calcium homeostasis,macrophage autophagy and pyroptosis pathways.Traditional Chinese medicine(TCM)has shown significant clinical efficacy in improving myocardial injury,but its mechanism of action needs to be thoroughly investigated. OBJECTIVE:To investigate the role of mitochondrial calcium homeostasis-mediated macrophage autophagy and pyroptosis pathways in myocardial injury,and to summarize the progress of TCM in this field. METHODS:A computerized search was performed for relevant literature from the database inception to March 2024 in the Web of Science,PubMed and CNKI.The search terms were"mitochondrial calcium homeostasis,macrophage autophagy,macrophage pyroptosis,traditional Chinese medicine,myocardial injury,myocardial injury reperfusion"in Chinese and English.Through literature review,we analyzed the relationship between mitochondrial calcium homeostasis and macrophage autophagy and pyroptosis,explored the mechanism of their roles in myocardial injury,and summarized the pathways of multi-targeted,multi-pathway effects of TCM. RESULTS AND CONCLUSION:The maintenance of mitochondrial calcium homeostasis has been found to be closely related to the normal function of cardiomyocytes.Macrophages can participate in the repair process of myocardial injury through autophagy and pyroptosis pathways.Autophagy contributes to cell clearance and regulation of inflammatory response,while pyroptosis affects myocardial repair by releasing inflammatory factors.TCM regulates mitochondrial calcium homeostasis and macrophage function through multiple mechanisms.For example,astragalosid regulates calcium homeostasis by lowering mitochondrial membrane potential and inhibiting cytochrome C,and epimedium glycoside plays a role in reducing β-amyloid deposition.In addition,herbal compounds and single drugs promote myocardial repair by activating or inhibiting specific signaling pathways,such as PI3K/AKT and nuclear factor-κB signaling pathways.Future studies should focus on the interactions between mitochondrial calcium homeostasis,autophagy and pyroptosis pathways,as well as how TCM can exert therapeutic effects through these pathways to provide new strategies and drugs for the treatment of myocardial injury.

Objective To analyze the core genes of lung ischemia-reperfusion injury and construct a competitive endogenous RNA (ceRNA) network. Methods Original data of GSE145989 were downloaded from the Gene Expression Omnibus (GEO) database as the training set, and the GSE172222 and GSE9634 datasets were used as the validation sets, and the differentially-expressed genes (DEG) were identified. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed. Protein-protein interaction (PPI) network was constructed, and the core genes were screened, and the diagnostic values of these core genes and the immune infiltration levels of immune cells were evaluated. The ceRNA network was constructed and validated. The targeted drugs based on ceRNA network were assessed. Results A total of 179 DEG were identified, including 61 down-regulated and 118 up-regulated genes. GO analysis showed that DEGs were associated with multiple biological processes, such as cell migration, differentiation and regulation, etc. They were correlated with cell components, such as vesicle membrane, serosa and membrane raft, etc. They were also associated with multiple molecular functions, such as chemokine receptor, G protein-coupled receptor, immune receptor activity and antigen binding, etc. KEGG pathway enrichment analysis revealed that DEG were involved in tumor necrosis factor (TNF), Wnt, interleukin (IL)-17 and nuclear factor (NF)-κB signaling pathways, etc. PPI network suggested that CD8A, IL2RG, STAT1, CD3G and SYK were the core genes of lung ischemia-reperfusion injury. The ceRNA network prompted that miR-146a-3p, miR-28-5p and miR-593-3p were related to the expression level of CD3G. The miR-149-3p, miR-342-5p, miR-873-5p and miR-491-5p were correlated with the expression level of IL-2RG. The miR-194-3p, miR-512-3p, miR-377-3p and miR-590-3p were associated with the expression level of SYK. The miR-590-3p and miR-875-3p were related to the expression level of CD8A. The miR-143-5p, miR-1231, miR-590-3p and miR-875-3p were associated with the expression level of STAT1. There were 13 targeted drugs for CD3G, 4 targeted drugs for IL-2RG, 28 targeted drugs for SYK and 3 targeted drugs for lncRNA MUC2. No targeted drugs were identified for CD8A, STAT1 and other ceRNA network genes. Conclusions CD8A, IL2RG, STAT1, CD3G and SYK are the core genes of lung ischemia-reperfusion injury. The research and analysis of these core genes probably contribute to the diagnosis of lung ischemia-reperfusion injury and providing novel research ideas and therapeutic targets.

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

Objective To explore the role and efficacy of VEGF and HGF gene adenovirus vector in promoting angiogenesis in ischemic tissue.Methods 84 Kunming mice were randomly divided into sham group,control group,VEGF group,HGF group and VEGF+HGF group,and the left lower limb ischemia model was established.The blood supply of ischemic tissue was observed by rheometer,and the expression levels of VEGF and HGF in each group were detected by Western Blot and ELISA.Immunohistochemical staining was used to detect angiogenesis(CD31,SMA)in ischemic tissues.Safety was assessed by side effects during treatment in mice.Results After the successful modeling,the blood flow velocity of the left lower limb in each group decreased significantly.On the 7th day after operation,the blood flow of the left lower limb in each group was significantly better than that on the 0th day after operation(P<0.05),and the blood flow of the left lower limb in Ad-VEGF-HGF group was significantly better than that in other groups(P<0.05).On the 28th day after operation,the blood flow of the left lower limb in Ad-VEGF-HGF group gradually stabilized,the blood flow in Ad-VEGF-HGF group was significantly better than that in other groups,and both VEGF group and HGF group were significantly better than the control group(P<0.05).On the 7th,14th,and 28th days following surgery,HGF and VEGF protein levels in the Ad-HGF,Ad-VEGF,and Ad-VEGF-HGF groups were substantially greater than those in the control group(P<0.05).The expression level in the Ad-VEGF-HGF group peaked on the 14th day(all P<0.001)and subsequently declined to preoperative levels on the 28th day after operation.Conclusion Ad-VEGF-HGF gene injection can effectively boost VEGF and HGF protein expression and rapidly reach the relative peak level,encour-aging angiogenesis after lower limb ischemia,increasing blood flow,and improving lower limb circulation.

Ferroptosis is a unique iron-dependent cell death pattern,a novel death phenotype distinct from apoptosis,va-rious forms of necrosis,and autophagy.Numerous active ingredients extracted from traditional Chinese medicine have been found to exert anti-cancer effects by inducing ferroptosis in various cancers.An increasing number of studies have found that the regulation of ferroptosis can influence the sensitivity of tumor cells to drugs and even reverse drug resistance.When combined with chemo-therapy drugs such as cisplatin,5-FU and gemcitabine,some natural products enhance cancer cells'sensitivity to chemothera-peutic drugs by inducing ferroptosis.This paper mainly summarizes traditional Chinese medicine and its natural products that can exert anti-cancer effects by inducing ferroptosis,providing new insights for cancer treatment and drug resistance reversal.Addition-ally,it contributes to exploring the potential advantages of traditional Chinese medicine,thereby expanding its scope of applica-tion.

Immune checkpoint inhibitors(ICIs)mainly including the CTL antigen 4(CTLA-4)and PD-1/PD-L1,which would offer a notable clinical benefit for non-small cell lung cancer(NSCLC)patients.By strengthening the antitumor immune re-sponse of the body,ICIs lead to immune-related adverse events(irAEs),including checkpoint inhibitor pneumitis(CIP).Although the clinical incidence of CIP is relatively low,some serious cases may prolong or terminate of immunotherapy,even life threateing.This article tries to summarize the clinical manifestations,pathological characteristics,biological mechanism,susceptible population,diagnosis and differential diagnosis,and integrated traditional Chinese and Western medicine treatment of CIP,in order to understand CIP more clearly.

Objective:To examine the impact of berberine on polycystic ovary syndrome (PCOS) in mice, and to investigate the effects of berberine on the intestinal flora and the intestinal flora on PCOS.Methods:A mouse model of PCOS was established by administering dehydroepiandrosterone in combination with high fat diet, and the mouse model was given a berberine treatment. The study consisted of a blank control group (C group), a PCOS model group (M group) and a berberine treatment group (T group). During the experiment, the mice were closely monitored through timed body weight measurements and estrous cycle monitoring; intraperitoneal glucose tolerance test and insulin tolerance test were done. Upon completion of the pharmacological intervention, the wet weights of liver, ovary and fat deposits of mice were assessed and subjected to HE staining to confirm the success of PCOS modeling and the efficacy of berberine. Additionally, fecal samples were analyzed for intestinal flora through 16S rRNA analysis.Results:The PCOS model was established successfully, berberine alleviated the disturbance of estrous cycle in mice, and significantly alleviated fat accumulation and metabolic abnormalities of glucose in mice. The cross-sectional area of fat pad cells in T group was (2 858±146) μm2, which was significantly lower than that in M group [(9 518±347) μm2], and the difference was statistically significant ( P<0.001). The blood glucose levels in T group were significantly lower than those in M group ( P<0.05). The composition and structure of intestinal flora in mice of M group with PCOS (compared with C group) and in mice of T group after berberine intervention (compared with M group) were significantly altered. However, alpha diversity did not change significantly among three groups ( P>0.05). Conclusion:Berberine could alleviate PCOS by intervening in the alterations of gut microbiota.
