ObjectiveTo explore the regulatory effects and mechanisms of Astragali Radix polysaccharide (APS) on inhibitor of differentiation1 (ID1) and protein kinase B (Akt) in gastric cancer. MethodsImmunohistochemical staining was used to detect the expression of ID1 and Akt in 61 gastric cancer tissue samples and 20 adjacent normal gastric tissue samples. Immunofluorescence was used to detect the localization of ID1 and Akt. The effects of APS at the concentrations of 0.625, 1.25, 2.5, 5, 10, 20 mg·L-1 on the proliferation of gastric cancer MGC-803 cells were examined by the cell counting kit-8(CCK-8) method and the colony formation assay. The target information of APS was retrieved from the Traditional Chinese Medicine Systems Pharmacology and Analysis Platform and Swiss Target Prediction. Keywords such as gastric cancer, gastric tumor, and stomach cancer were searched against GeneCards, UniProt, DisGeNET, and Online Mendelian Inheritance in Man (OMIM) for the screening of gastric cancer-related targets. The online tool jvenn was used to create the Venn diagram to identify the common targets, and STRING and Cytoscape were used to construct the protein-protein interaction network. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were conducted via R 4.2.2 to predict the potential roles of APS in the development of gastric cancer. The cell scratch assay was employed to assess the effect of APS on the migration of MGC-803 cells. The protein and mRNA levels of ID1 and Akt in the cells treated with APS were determined by Western blot and Real-time PCR, respectively. ResultsCompared with the adjacent normal gastric tissue, the gastric adenocarcinoma tissue showed increased positive expression of ID1 (χ2 =81.00, P<0.01). Immunofluorescence detection showed that ID1 and Akt were mainly located in the cytoplasm of gastric adenocarcinoma cells. Bioinformatics analysis identified 14 common genes shared between APS and gastric cancer. The average degree of protein-protein interaction network nodes was 14.29. GO and KEGG pathway enrichment results showed that ID1 and Akt were significantly enriched in the Rap1 and phosphatidylinositol-3-kinase (PI3K) /Akt signaling pathways. Cell experiments demonstrated that 5-fluorouracil (0.1 mg·L-1) and APS (10, 20 mg·L-1) groups showed decreased cell proliferation, migration, and colony formation. Compared with the control group, 10, 20 mg·L-1 APS inhibited the proliferation of MGC-803 cells (P<0.01), with 10 mg·L-1 APS demonstrating stronger inhibitory effect. In addition, APS at 10, 20 mg·L-1 inhibited the migration (P<0.01) and colony formation (P<0.05, P<0.01) of MGC-803 cells. Compared with the control group, APS at 10, 20 mg·L-1 down-regulated the protein levels of ID1 (P<0.01) and Akt (P<0.05) and the mRNA levels of ID1 (P<0.05, P<0.01) and Akt (P<0.05, P<0.01) in MGC-803 cells. ConclusionID1 and Akt are highly expressed in the gastric adenocarcinoma tissue, which may be related to the development of gastric cancer. APS can down-regulate the protein and mRNA levels of ID1 and Akt to exert anti-tumor effects, which is expected to provide new therapeutic targets for gastric cancer treatment.

Aim To investigate the effects of bone-forming protein BMP9 on aerobic glycolysis,migration and invasion ability in triple-negative breast cancer MDA-MB-231 cells and the underlying mechanisms.Methods The experimental group infected MDA-MB-231 cells with human BMP9 recombinant adenovirus(AdBMP9),while the control group infected cells with empty GFP adenovirus.Lactate,glucose and ATP as-say kits were used to detect glucose uptake,lactate and ATP production.The correlation between BMP9 and key glycolytic enzyme genes in pancarcinoma was ana-lyzed using GEPIA2 database.The mRNA expression levels of GLUT1,HK2,PKM2 and LDHA in MDA-MB-231 cells after overexpression of BMP9 were detec-ted by qRT-PCR.Potential targets of BMP9 inhibiting MDA-MB-231 aerobic glycolysis were analyzed in STRING database.The expression levels of HIF-1αand downstream protein were detected by Western blot.The changes of cell migration and invasion ability after different treatments were evaluated by the scratch heal-ing assay and Transwell assay.Results Compared with the control group,BMP9 down-regulated glucose uptake,lactate production,ATP level(P<0.01),and inhibited HIF-1α and its downstream protein ex-pression in MDA-MB-231 cells.Overexpression of HIF-1α in rescue experiment reversed the inhibitory effect of BMP9 on aerobic glycolysis,migration and in-vasion of MDA-MB-231 breast cancer cells.Conclu-sion BMP9 down-regulates HIF-1α to inhibit the aer-obic glycolysis and migration and invasion ability of MDA-MB-231 breast cancer cells.

Aim To investigate the changes in the proliferation and apoptosis of Siha cells after knocking down Rho GTPase-activating protein 30(ARHGAP30).Methods After designing specific shARHGAP30 primers and connecting them to the pLKO.1 vector,we transformed them into Escherichia coli competent cells,then co-transfecting them with lentiviral helper plasmids into HEK-293T cells.We collected and filtered cell supernatant to obtain the vi-rus to infect Siha cells.RT-qPCR and Western blot were used to detect knockdown efficiency,as well as changes in the expression of Bax and Bcl-2 after trans-fection.The CCK-8 method was employed to measure the proliferation level of cells after knockdown.Results After successful construction of a lentiviral plasmid with knockdown of the ARHGAP30 gene and establish-ment of stably transfected Siha cells,ARHGAP30 tran-scription and translation(P<0.01)in Siha cells de-creased,Bax/Bcl-2 significantly decreased(P<0.01),indicating decreased apoptosis and increased cell proliferation(P<0.01).Conclusions This study suggests the involvement of ARHGAP30 in the proliferation and apoptosis of Siha cells,and regulating the ARHGAP30 gene may interfere with the occurrence and development of cervical cancer.

Coronary atherosclerotic heart disease(CHD)is an ischemic cardiovascular condition caused by the narrowing or blockage of the vascular lumen due to coronary atherosclerosis.Clinically,it presents as angina pectoris,heart failure,or sud-den cardiac death,and stands as one of the primary causes of mortality among both urban and rural populations in China.Cir-cRNA,classified as non-coding RNAs,can function as upstream regulatory molecules for miRNA or RNA-binding proteins.They actively participate in various pathological processes associated with CHD,including endothelial cell dysfunction,smooth mus-cle cell migration,macrophage-derived foam cell formation,an-giogenesis,myocardial injury,and repair,as well as post-in-farction heart failure.The expression pattern of these molecules is highly specific to the illness and tissue,indicating their poten-tial as therapeutic targets for disease management and as biomar-kers.Furthermore,they also open up new avenues for drug tar-get development in the field of traditional Chinese medicine.This article aims to provide an overview of the recent research progress on circRNA in the regulation of coronary heart disease,as well as the mechanisms involved in traditional Chinese medi-cine.It serves as a valuable reference for future research on cor-onary heart disease.

Objective To explore the effect of cardiac shock wave therapy(CSWT)on ST deviation of electrocardiogram and myocardial perfusion imaging in coronary artery disease(CAD)patients.Methods CAD patients who received CSWT in Cardiology Department of Beijing Hospital from December 2016 to August 2022 were enrolled.Three months of CSWT were conducted with a total of 9 times shock wave treatment.Clinical data,myocardial perfusion imaging data and stress electrocardiogram data were collected.Myocardial perfusion score,electrocardiographic data were compared before and after CSWT.Results A total of 55 patients were finally enrolled.There were 43 male and 12 female patients with an average age of(67.45±8.96)years old.ST deviation on 12 leads of electrocardiogram did not show significant difference before and after CSWT.Myocardial perfusion imaging showed global stress perfusion score(P=0.031)and reverse perfusion score(P=0.024).Global rest ischemia score reduced after CSWT(P=0.034).Target stress perfusion score(P=0.002),target reverse perfusion score(P=0.002),target reverse ischemic area(P=0.001)were improved after CSWT.Conclusions CSWT may not influence ST deviation of electrocardiogram,but may improve myocardial ischemia in CAD patients,
