ObjectiveEndothelial cell dysfunction being the core link. This study explores the molecular mechanism of Danshen Tongluo formula in treating coronary artery disease-dominated panvascular disease with endothelial cell changes as the core through animal experiments and single-cell transcriptome sequencing. MethodsA rat model of coronary artery disease-dominated panvascular disease was established by ligating the left anterior coronary artery. Rats were randomized into a blank group， a model group， and a Danshen Tongluo formula （28 mg·kg^-1·d^-1） group. The efficacy was evaluated by examining the cardiac ultrasound， determination of the plasma level of N-terminal pro-brain natriuretic peptide， and pathological staining. After single-cell sequencing， SingleR package， public datasets， and related literature were used for annotation of the cells. Cell chat was used for intercellular communication and ligand-receptor analysis， and scmetabolism was used for metabolic analysis of endothelial cells. ResultsAnimal experiments showed that Danshen Tongluo formula reduced the N-terminal pro-brain natriuretic peptide （ NT-proBNP ） level （P<0.05）， ameliorated myocardial cell damage and fibrosis， and increase left ventricular ejection fractions （LVEF） in the rat model of heart failure after myocardial infarction（P<0.05）. Single-cell sequencing results showed that Danshen Tongluo formula increased the proportion of arterial endothelial cells， venous endothelial cells， and capillary-arterial endothelial cells， while reducing the proportion of capillary-venous endothelial cells. In addition， this formula increased the interaction intensity of endothelial cells with cardiomyocytes and M1 macrophages and reduced the interaction intensity of endothelial cells with fibroblasts and T cells. Danshen Tongluo formula upregulated CXCL12-CXCR4 signaling in endothelium-B cells and Ptprm-Ptprm signaling in endothelial endothelial cells， while downregulating Mif-（CD74⁺CXCR44） signaling in endothelium-M1 macrophages and Mif-（CD74⁺CD44） signaling in endothelium-M2 macrophages. It reduced the citric acid cycle， oxidative phosphorylation， and glycolysis and increased the glycolysis/oxidative phosphorylation ratio in endothelial cells. GO and KEGG enrichment analysis showed that arterial endothelial cells， venous endothelial cells， and venous capillary endothelial cells can all regulate oxidative phosphorylation， cell adhesion molecules， and tyrosine metabolism. Lymphatic endothelial cells regulate immunity and vascular constriction to participate in the metabolism of various amino acids and fatty acids. ConclusionDanshen Tongluo Formula can ameliorate coronary artery disease-dominated panvascular disease by changing the composition of endothelial cells and regulating the communication between myocardial endothelial cells and non-endothelial cells.

Objective To explore the efficacy of the self-formulated Zhuzhang Formula in trea-ting the spleen deficiency with dysfunction of transportation syndrome of idiopathic short stature(ISS)and its effects on the growth rate,disease-related indicators,and bone metabolism indicators in affect-ed children.Methods A total of 80 children with ISS were enrolled as study subjects.They were randomly assigned to control group and observation group using random number table method,with 40 cases in each group.The control group received conventional western medicine treatment,while the observation group was administered self-formulated Zhuzhang Formula in addition to the treatment of the control group.Comparisons were made between the two groups in terms of clinical efficacy,TCM syndrome scores,growth parameters(monthly average height increment,annual growth rate),levels of disease-related indicators[serum insulin-like growth factor-1(IGF-1),bone morphogenetic pro-tein-2(BMP-2),insulin-like growth factor binding protein-3(IGFBP-3)],levels of bone metabo-lism indicators[bone alkaline phosphatase(BAP),type Ⅰ procollagen N-terminal propeptide(PⅠNP),type Ⅰ collagen cross-linked C-terminal telopeptide(β-CTX)],and the incidence of adverse reac-tions.Results The overall effective rate in the observation group was 97.50％,which was significantly higher than the 80.00％ in the control group(P＜0.05).After 3 and 6 months of intervention,the scores for symptoms such as short stature,sallow complexion,loss of appetite,weak voice and shortness of breath,limb weakness,and loose stools,as well as the total TCM syndrome scores,were lower in the observation group than those in the control group,with statistically significant differences(P＜0.05).After 6 months of intervention,the monthly average height increment and annual growth rate were higher in the observation group than those in the control group,and the differences were statistically significant(P＜0.05).After 3 and 6 months of intervention,the levels of IGF-1,BMP-2,IGFBP-3,BAP,and PⅠNP were higher in the observation group than those in the control group,while the level of β-CTX was lower,and the differences were statistically significant(P＜0.05).There was no statistically significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion The self-formulated Zhuchang Formula demon-strates remarkable efficacy in treating the spleen deficiency with dysfunction of transportation syndrome of ISS.It can alleviate clinical symptoms by regulating the levels of IGF-1,BMP-2,IGFBP-3,and bone metabolism indicators,thereby promoting the growth and development of affected children,and exhibits high safety.

Objective To analyze the impact of sarcopenia on the efficacy and adverse reactions of immunotherapy combined with chemotherapy in patients with advanced gastric cancer.Methods Patients with locally advanced or metastatic gastric cancer confirmed by pathology who were not eligible for radical surgery were selected as study subjects.A body composition analyzer was used to measure the appendicular muscle mass of the patients and calculate the skeletal muscle mass index(SMI).Based on the SMI,the patients were divided into sarcopenia group and non-sarcopenia group.On the basis of nutritional intervention and comprehensive exercise therapy,the patients were administered immu-notherapy combined with chemotherapy.The efficacy and adverse reactions were evaluated.The primary endpoint was progression-free survival(PFS),and the secondary endpoints were the objec-tive response rate(ORR)and treatment-related adverse reactions.Results A total of 52 gastric cancer patients were included,with 23 in the sarcopenia group and 29 in the non-sarcopenia group.The median PFS in the non-sarcopenia group was 9.8 months(95％CI,8.9 to 12.4),and was 5.4 months in the sarcopenia group(95％CI,4.9 to 8.1).The median PFS in the non-sarcopenia group was longer than that in the sarcopenia group,and the difference was statistically significant[HR(95％CI)=0.41(0.23 to 0.73),P=0.003].The results of the multivariate Cox propor-tional hazards regression model showed that comorbidities,treatment cycles,and sarcopenia were all independent prognostic factors affecting the PFS of gastric cancer patients(P＜0.05).The ORR in the non-sarcopenia group was 48.28％(14/29),and was 17.39％(4/23)in the sarcopenia group(x2=5.276,P＜0.05).Treatment-related adverse reactions with grading ≥3 in both groups were mainly hematological toxicities.In the non-sarcopenia group,the incidence of grading ≥ 3 treat-ment-related adverse reactions was 27.59％(8/29),and the incidence of grading＜3 treatment-re-lated adverse reactions(including those with no adverse reactions)was 72.41％(21/29).In the sarcopenia group,the incidence of grading ≥3 treatment-related adverse reactions was 56.52％(13/23),and the incidence of grading＜3 treatment-related adverse reactions(including those without adverse reactions)was 43.48％(10/23).The incidence of grading ≥3 treatment-related adverse reactions in the non-sarcopenia group was lower than that in the sarcopenia group(P=0.035).Conclusion For patients with locally advanced or metastatic gastric cancer complicated with sarcopenia,the median PFS of immunotherapy combined with chemotherapy is shorter,the ORR is lower,and the incidence of treatment-related adverse reactions is increased.Therefore,ear-ly intervention for sarcopenia should be implemented to improve the quality of life of patients with advanced gastric cancer.

Forty adult male C57BL/6 mice were randomly divided into four groups:the control group,Salmonella typhimurium(S.typhimurium)(ST)group,phlorizin(PHZ)+S.typhimuri-um(ST)group,and PHZ(80 mg/kg)group,with 10 mice in each group.Morphological observa-tion,HE staining,ELISA,immunofluorescence and Western blot were performed,the results showed that PHZ significantly increased the cecal index,decreased the spleen index of S.typhi-murium-induced mice(P＜0.05),and reduce the pathological damage of cecum in mice.Mean-while,PHZ treatment also significantly reduced colonization of S.typhimurium in the cecum,spleen,mesenteric lymph nodes and liver(P＜0.05).The results of ELISA showed that PHZ treatment also significantly inhibited the S.ty phimurium-induced increase in the expression of IL-1β,INF-γ,TNF-a and IL-6 in the cecum of mice(P＜0.05).Immunofluorescence and Western blot results showed that PHZ significantly increased the protein expression levels of Occludin,Claudin-3,and ZO-1 in the cecal barrier of mice induced by S.typhimurium(P＜0.05).These results con-firmed that phlorizin could improve cecal inflammation and intestinal barrier damage induced by S.typhimurium in mice.
