Objective:To explore the value of two-dimensional speckle tracking echocardiographic imaging (2D-STI) for assessing partial and global left ventricular functional changes at pre-and post-percutaneous coronary intervention (PCI) in patients with chronic total coronary occlusion.
Methods:Echocardiograph was conducted in 23 chronic total coronary occlusion patients at pre-PCI and 1 day, 3, 6 months post-PCI to examine left ventricular ejection fraction (LVEF), meanwhile 2D-STI was applied to obtain the global longitudinal strain (GLS) value of left ventricle.
Results:In all 23 patients, for LVEF, compared with pre-PCI (59.29±12.15)%, it was increased at 3 and 6 months post-PCI (60.00±12.35)%and (61.37±11.8)%respectively, all P<0.05;for GLS value, compared with pre-PCI (-12.77d wit )%, it was decreased at 1 day and 3, 6 months post-PCI (-13.23ecrea)%and (-15.67ecrea)%, (-16.97ecrea)%respectively, all P<0.05.
Conclusion:PCI could effectively improve left ventricular function in patients with chronic total coronary occlusion, 2D-STI technology may quantitatively assess those changes at the early stage.

Objective:To analyze the expression and clinical significance of serum microRNA (miR)-622 and miR-944 in patients with epithelial ovarian cancer.Methods:Seventy patients with ovarian epithelial cancer admitted in Yuyao People′s Hospital from January 2018 to June 2021 were selected as the study group, and 50 patients with benign ovarian tumors were selected as the control group. The expression of serum miR-622, miR-944 and the expression of tumor tissue protein E cadherin, mitogen-activated protein kinase-1(MAPK1), extracellular regulated protein kinases (ERK) were detected in both groups, and the correlation between miR-622, miR-944 and tumor tissue protein were analyzed. The receiver operating characteristic (ROC) curve was drawn to analyze the efficacy of miR-622 and miR-944 in the diagnosis of ovarian epithelial cancer.Results:The levels of serum miR-622, miR-944 and the expression of E-cadherin, MAPK1 and ERK in the study group were higher than those in the control group: 14.72 ± 1.87 vs. 5.94 ± 1.26, 13.02 ± 1.65 vs. 4.15 ± 0.62, (5.12 ± 0.77) scores vs. (2.37 ± 0.34) scores, (6.47 ± 1.09) scores vs. (2.56 ± 0.45) scores, (5.58 ± 0.86) scores vs. (1.87 ± 0.28) scores, there were statistical differences ( P<0.05). The serum levels of miR-622, miR-924 were positively correlated with the expression of E-cadherin, MAPK1 and ERK ( P<0.05). The area under the curve of miR-622, miR-944 and combined diagnosis of ovarian epithelial cancer were 0.763, 0.797, 0.808, respectively. Conclusions:The serum level of miR-622 and miR-944 were up-regulated in the patients with ovarian epithelial cancer, which was positively correlated with the expression of E-cadherin, MAPK1 and ERK protein in tumor tissues.
