Objective To explore the correlation among ST-2,adiponectin(APN),positive growth dif-ferentiation factor -15(GDF-15)and senile heart failure,and to investigate the diagnostic values of these indica-tors. Methods Totally 129 patients(15 patients of NYHA Ⅰ,60 of NYHA Ⅱ,28 of NYHA Ⅲ and 26 of NYHAⅣin study group)with heart failure and 30 control subjects(control group)were enrolled in the study.Se-rum levels of ST-2,APN and GDF-15 were determined by ELISA,and their correlation with senile heart failure was analyzed.Results Compared with those in control group,serum levels of ST-2,APN and GDF-15 in study group were significantly increased(P<0.05).There were significant differences in serum levels of ST-2,APN and GDF-15 among patients of different classifications in study group(P<0.05)and the higher level of cardiac func-tion,the higher serum ST-2,APN and GDF-15. There was a positive correlation among serum ST-2,APN and GDF-1. Conclusions The serum levels of ST-2,APN and GDF-1 are positively related to the severity of senile heart failure,thus it could be served as the index of diagnosis,curative effect monitoring and prognosis of patients with heart failure.

[Abstract] Objective: To investigate the effect of apatinib (APA) combined with cisplatin (DDP) on the proliferation, invasion and migration capacity of gastric carcinoma (GC) cells and its molecular mechanism. Methods: Cancer and para-cancerous tissue samples resected from 50 GC patients, who were surgically treated in Wuwei People's Hospital from January 2016 to June 2019, were collected for this study; in addition, GC cell lines MGC803 and SGC7901 were also collected. qPCR was used to detect the HMGA2 expression in tissues and mRNA expressions of molecules related to cell proliferation, migration and invasion in GC cell lines. MGC803 and SGC7901 cells were transfected with pcHMGA2 by liposome transfection technology. After treatment with DDP and APA at different concentrations, the cells were divided into NC, pcHMGA2, pcHMGA2+DDP and pcHMGA2+DDP+APA groups. Protein expression of HMGA2 in GC cells was detected by Western blotting, and proliferation, migration and invasion of the cells were detected by MTT and Transwell assay, respectively. Results: The mRNA expression of HMGA2 in GC tissues was higher than that in para-cancerous tissues (P<0.05), and the survival rate of GC patients in the high expression group was significantly reduced (P<0.01). DDP significantly inhibited the proliferation, invasion and migration of MGC803 and SGC7901 cells (all P<0.01); the proliferation, invasion and migration of MGC803 and SGC7901 cells in DDP+APA group significantly decreased (all P<0.01) as compared with DDP group; APA significantly enhanced the inhibitory effect of DDP on HMGA2 expression in GC cells (P<0.01); APA enhanced the anticancer activity of DDP against GC by down-regulating HMGA2 expression. Conclusion: APA promotes the anticancer activity of DDP against GC, and its molecular mechanism is the promotion of the inhibitory effect of DDP on HMGA2 expression.
