Objective To investigate the shape and function of right ventricles in patients received heart transplantation(HT). Methods Sixty healthy volunteers(control group) and 31 HT patients(HT group) were enrolled, and the HT group was further divided into the nonrejected(HTn) group and the rejected(HTp) group based on the endomyocardial biopsy(EMB) results. All the participants received routine echocardiography. Single beat real-time three-dimensional echocardiography (sRT-3DE) was performed in all to evaluate parameters concerning modality and systolic function of participants' right ventricles. Results 1) Right ventricular stroke volume (RVSV) and right ventricular ejection fraction (RVEF) were significantly different among the groups[RVSV: control group vs HTn group vs HTp group was (56.18 ± 23.72)ml vs (36.08 ± 10.94)ml vs (26.22 ± 9.84)ml, P ＜0.0001; RVEF:control group vs HTn group vs HTp group was (62.09± 7.18)% vs (51.04 ± 7.58) vs (35.86 ± 9.86)%, P ＜0.00001＝.2＝ When taking the influence of rejection into consideration,RVEF was proved to be a stable and sensitive indicator. Conclusions sRT-3DE can quickly assess shape and systolic function of right ventricle.RVEF was the most stableand sensitive among all the RV-related indicators and is a promising indicator in the clinic follow-up of HT patients.

Objective:To explore the effect and mechanism of miRNA sponge on the epithelial-mesenchymal transition (EMT) of gastric carcinoma cell lines SGC7901. Methods:Synthetic ZEB2 3'UTR plasmid and siRNA targeting ZEB2 were transfected into the SGC7901 cell line by Lipofectamine 2000. Real-time quantitative polymerase chain reaction was performed to evaluate the expres-sion levels of miR-200a/b/c. Finally, the migratory, invasive, and proliferative activities of the gastric carcinoma cells in vitro were ana-lyzed by the scratch test, the Transwell cell invasion, and the cell cloning assay. The expression of the target protein was detected by Western blot. Results:Compared with the control group, the expressions of miR-200a/b/c significantly decreased, and their migration, invasion, and proliferation capabilities were considerably higher after they were transfected with ZEB2 3'UTR. Although the expres-sions of miR-200a/b/c significantly increased, the migratory, invasive, and proliferative activities of SGC7901 cells also degraded after they were transfected with siRNA targeting ZEB2. The expression of ZEB2 increased, and that of E-cadherin decreased at the protein level after they were transfected with ZEB2 3'UTR. The protein expression of Vimentin in SGC7901 cells significantly increased. The indicators show the opposite trend when cells were transfected with siZEB2, and the differences between the control and mutation groups were insignificant. Conclusion:ZEB2 3'UTR can regulate EMT course by regulating the miR-200a/b/c expression in gastric car-cinoma, consequently regulating the invasion and migration of carcinoma cells.

Objective To assess the clinical usefulness and value of the 5 models for the prediction of acute kidney injury (AKI),severe AKI which renal replacement treatment was needed (RRT-AKI) and death after cardiac surgery procedures in Chinese patients.Methods One thousand and sixty-seven patients who underwent cardiac surgery procedures in the department of cardiac surgery in the Zhongshan Hospital,Fudan University between May 2010 and January 2011 were involved in this research.The predicting value for AKI (AKICS),RRT-AKI (Cleveland,SRI and Mehta score) and death (EURO score) after cardiac surgery procedures was evaluated by Hosmer-Lemeshow goodness-of-fit test for the calibration and area under receiver operation characteristic curve (AUROC)for the discrimination.Results The incidence of AKI was 20.34％(217/1067),and 63.13％ of their renal function recovered completely.The incidence of RRT-AKI was 3.56％(38/1067) and the mortality of AKI and RRT-AKI was 9.68％ (21/217) and 44.73％ (17/38) respectively.The total mortality was 3.28％ (35/1067).The discrimination and calibration for the prediction ofAKI of AKICS were low.For the prediction ofRRT-AKI,the discrimination and calibration of Cleveland score were high enough,but the predicated value was lower than the real value (1.70％ vs 3.86％).The discrimination of Mehta score and the calibration of SRI were low.The discrimination and calibration for the prediction of death of EURO score was low.Conclusion According to the 2012 KDIGO AKI definition,none of the 5 models above is good at predicting AKI after cardiac surgery procedures.Cleveland score has been validated to have a proper impact on predicting RRT-AKI after cardiac surgery procedures,but the predicting value is still in doubt.EURO score has been validated to have an inaccurate predicting value for death after cardiac surgery procedures.

Objective To explore the effects of zinc finger E-box binding protein (ZEB)2 3′UTR gene transfection on proliferation, invasion and migration in human gastric epithelial cell line GES-1. Methods The synthetic ZEB2 3′UTR and miR-200b micmics were transfected into GES-1 cell line by lipofectamine 2000. We set up control grop, the mutation group and ZEB2 3′UTR group. Real-time quantitative PCR was performed to evaluate the expression levels of miR-200a/b/c and ZEB1/ZEB2 mRNAs after transfection.And then we set up control group, ZEB2 3′UTR group, ZEB2 3′UTR+negative control group and ZEB2 3′UTR+miR-200b micmics group. The protein expression levels of ZEB1, ZEB2, matrix metallopro-teinases (MMP) 2/9 and proliferating cell nuclear antigen (PCNA) were detected by Western blot assay. The invasion and mi-gration capability were analyzed by transwell assay and wound healing test. MTT assay was used to detect the proliferation ability. Results Compared with control group and mutation group, the expressions of miR-200a/b/c were significantly de-creased, especially for miR-200b. And the expressions of ZEB1/ZEB2 were significantly increased at both mRNA and pro-tein levels after transfected with the ZEB2 3′UTR, enhancing the capability of migration,invasion,and proliferation (P <0.05). Compared with ZEB2 3′UTR group, the capabilities of proliferation,invasion and migration were significantly lower in combined group. Conclusion ZEB2 3′UTR can increase the ability of cell proliferation, invasion and metastasis through regulating the levels of miR-200a/b/c, and then influence the regulation of transcription of the target gene, which could lead to malignant transformation of GES-1 cells.
