To study the variation and significance of plasma coagulation factor VII (FVII) in different kinds of ischemia heart disease (IHD) and examine its relation with plasma lipid and gene polymorphism. FVIIa was determined with one stage clotting assay by using a recombinant soluble tissue factor (rsTF). FVIIc was measured with one stage clotting assay. FVIIag was quantified with an enzyme-linked immunosorbent assay (ELISA). Polymorphism was analyzed with PCR-urea-polyacrylamide gel electrophoresis. Our results showed that FVIIa in stable angina (SA), unstable angina (UA), obsolete and acute myocardial infraction (OMI, AMI) patients was higher than those of normal group with the differences being significant within any two groups. FVIIag in UA, OMI and AMI was higher than those in SA and normal groups. There were positive correlations between FVIIa and serum triglycerides, FVIIa and FVIIc, FVIIc and FVIIag. FVII-323 0/10 bp polymorphism analysis was performed in 60 patients and 0/10 bp polymorphism was found in 5 cases. FVIIc and FVIIag were much lower in cases of 0/10 bp groups than those in cases of 0/0 bp groups. It is concluded that there was activation of extrinsic coagulation pathway in every kind of IHD to different extent. FVIIa was the risk factor in the development of IHD, and more sensitive in reflecting the severity of cardiovacutar disease than FVIIc or FVIIag. FVIIa was higher in OMI, which may be one of the risk factors of re-infraction. Serum triglyceride may indirectly lead to the development of IHD by increasing the level of FVIIa. FVII-323 0/10 bp polymorphism was present in Chinese patients with IHD and it was correlated with the level of FVIIc, FVIIag in plasma. 10 bp allelomorphic gene was a protective factor against thrombogenesis.

OBJECTIVETo investigate the effect of novel porous calcium phosphate cement (CPC) scaffoldings on attachment, proliferation and differentiation of bone marrow mesenchymal stem cells (BMSCs).
METHODSBMSCs of Beagle dogs were implanted and cultured with CPC scaffoldings in vitro, tricalcium phosphate (TCP) and poly (lactide-coglycolide) (PLGA) scaffoldings as controls. The attachment, proliferation and differentiation of BMSCs were detected through morphological characters, growth curve and the semi-quantitative detection of alkaline phosphatase (ALP) and osteocalcin (OC) activity.
RESULTSCell morphology and growth curve illustrated that BMSCs attached to and grown better on the surface of novel porous CPC scaffoldings than that of PLGA group (P < 0.05). Semi-quantitative analysis of ALP showed that ALP expression level in BMSCs on the CPC and TCP group were significantly higher than that of the PLGA group (P < 0.05), the CPC group was slightly higher than the TCP group, but no significant difference was found between the two groups (P > 0.05). The staining and semi-quantitative analysis results of OC demonstrated that calcium deposition of the PLGA group was significantly less than the CPC and TCP group on both observation point (P < 0.05), but no significant difference between the CPC and TCP group (P > 0.05).
CONCLUSIONThe novel porous CPC material used in this study has good biocompatibility similar to TCP but much better than PLGA which is favorable of BMSCs adhesion, proliferation and osteogenic differentiation. The novel porous CPC material is a suitable scaffolding for BMSCs to fabricate tissue-engineered bone in vitro.

PURPOSE: Colorectal cancer (CRC) is the third most common cancer in China and poses high morbidity and mortality. In recent years, increasing evidence has indicated that microRNAs played important functions in the occurrence and development of tumors. The purpose of this study was to identify the biological mechanisms of miR-362 in CRC. MATERIALS AND METHODS: Quantitative real-time PCR was carried out to assess the expression of miR-362 and SIX1. The Kaplan-Meier method was employed to evaluate the 5-year overall survival of CRC patients. The proliferative and invasive abilities of CRC cells were assessed by MTT and transwell assays. RESULTS: miR-362 was significantly decreased in CRC tissues and cell lines, compared to the normal tissues and normal cells. A significant connection was confirmed between the overall survival of 53 CRC patients and low expression of miR-362. Downregulation of miR-362 inhibited the proliferation and invasion through binding to the 3′-UTR of SIX1 mRNA in CRC. Additionally, we discovered that SIX1 was a direct target gene of miR-362 and that the expression of miR-362 had a negative connection with SIX1 expression in CRC. SIX1 could reverse partial functions in the proliferation and invasion in CRC cells. CONCLUSION: miR-362 may be a prognostic marker in CRC and suppress CRC cell proliferation and invasion in part through targeting the 3′-UTR of SIX1 mRNA. The newly identified miR-362/SIX1 axis provides insight into the progression of CRC.
