Objective To investigate the efficiency of European System for Cardiac Operative Risk Evaluation(EuroSCORE)in predicting in-hospital mortality for the patients after percutaneous coronary intervention(PCI). Methods Retrospective analysis was conducted on the patients who had undergone PCI in our hospital since year 2005 to 2007. We used both cumulative EuroSCORE score and logistic EuroSCORE to predict the in-hospital morality and to analyze the correlation between the predicted mortality and the actual mortality. Results According to the additive EuroSCORE, we divided the patients into three groups, the additive EuroSCORE 0-2 were divided into low-risk group,3-5 were divided into mid-risk group and ≥6 into high-risk group.The actual in-hospital mortality rates were 0%, 0.47% and 6.09% respectively. The EuroSCORE model demonstrated an overall relation between the EuroSCORE ranking and the incidence of in-hospital mortality(P<0.001). Results from the multivariable logistic regression analysis showed that the EuroSCORE was an independent in-hospital mortality predictor(P<0.01). Conclusion The EuroSCORE risk model and the in-hospital mortality were significantly correlated, indicating that the model was a promising method for predicting the in-hospital mortality of PCI patients.

OBJECTIVETo investigate the change of gastric cancer cell proliferation and the expression of gastric cancer related gene 213 (GCRG213), a long interspersed nuclear element-1 (LINE-1) endonuclease variant, during hypoxia.
METHODSNormal gastric mucosa cell GES-1 and gastric cancer cell BGC-823 were cultured in 20% or 3% oxygen concentrations, respectively. MTT test was used to analyze the proliferation of the GES-1 and BGC-823 cells. The change of GCRG213 mRNA and protein expression in GES-1 and BGC-823 cells was detected by using RT-PCR and Western blot analysis. Blast was used at the NCBI Blast server to identify GCRG213 sequence to any alignment in the GeneBank databases.
RESULTSCompared with 20% oxygen condition, 3% oxygen concentration could promote cell growth. Mean-while, the expression of GCRG213 at mRNA and protein levels was increased. GCRG213 sequence shared high homology with LINE-1 endonuclease sequence.
CONCLUSIONGCRG213 is a variant of LINE-1 endonuclease. Hypoxia as in 3% oxygen condition can promote cell proliferation and lead to GCRG213 overexpression.

BACKGROUNDOverexpression of G-protein coupled receptor 34 (GPR34) affects the progression and prognosis of human gastric adenocarcinoma, however, the role of GPR34 in gastric cancer development and progression has not been well-determined. The current study aimed to investigate the effect of GPR34 knockdown on the proliferation, migration, and apoptosis of HGC-27 gastric cancer cells and the underlying mechanisms.
METHODSThe expression of GPR34 in gastric cancer cell line HGC-27 was detected by quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting. HGC-27 cells were employed to construct the stable GPR34 knockdown cell model in this study. Real-time RT-PCR and Western blotting were applied to validate the effect of short hairpin RNA (ShRNA) on the expression of GPR34 in HGC-27 gastric cells. The proliferation, migration of these cells were examined by Cell Counting Kit-8 and transwell. We also measured expression profile of PI3K/PDK1/AKT and ERK using Western blotting.
RESULTSThe ShRNA directed against GPR34 effectively inhibited both endogenous mRNA and protein expression levels of GPR34, and significantly down-regulated the expression of PIK3CB (P < 0.01), PIK3CD (P < 0.01), PDK1 (P < 0.01), phosphorylation of PDK1 (P < 0.01), Akt (P < 0.01), and ERK (P < 0.01). Furthermore, GPR34 knockdown resulted in an obvious reduction in HGC-27 cancer cell proliferation and migration activity (P < 0.01).
CONCLUSIONSGPR34 knockdown impairs the proliferation and migration of HGC-27 gastric cancer cells in vitro and provides a potential implication for therapy of gastric cancer.
