Objective To assess the changes in blood coagulation after infusion of hydroxyethyl starch 45/ 0.7(molecular weight = 450000 Dalton, 70% of glucose units have been substituted) ,200/0.62, 200/0.5 and 130/0.4.Methods Forty rabbits weighing (2.6 ?0.5)kg were randomly divided into 5 groups of 8 animals each: group I HES450/0.7; group II HES 200/0.62; group III HES200/0.5; group IV HES 130/0.4; group V 0.9% NaCl. The animals were anesthetized with intramuscular seconal and ketamine. Hydroxyethyl starch or normal saline was infused at 10 ml?kg-1?h-1 for 3 h. Blood samples were taken before and 1,2,3 h after staring the infusion for determination of prothrombin time ( PT), activated partial thromboplastin time (APTT) and fibrinogen level (FIb) and thromboelastograph examination (TEG) .Results (1) After infusion of 30 ml?kg-1 HES 450/0.7 or 200/0.62 (in group I and II ) R time (representing the rate of initial fibrin formation) and K time (coagulation time) were significantly prolonged (P

Objective To explore the effect of trans-theoretical-model-based home visiting on hip function in community patients after hip joint replacement. Methods We chose 65 patients after hip joint replacement from January 2015 to March 2016 in our hospital:32 patients on odd days were set as the control group, where routine home visiting was done and the other 33 on even days as the experimental group, where community visiting based on trans-theoretical model. The two groups were compared in terms of Harris hip score at discharge and 6 months after discharge. Result The Harris hip score in the intervention group was significantly higher than that in the control group 6 months after discharge (P<0.05) and the hip function of the intervention group was better than that of the control group. Conclusions Community home visiting based on theoretical model can improve the hip function of patients after hip joint replacement compared with conventional health education models. This intervention method is worthy of popularization and application in community health education.

Objective:To investigate the expression, regulation, potential mechanism and clinical significance of microRNA(miRNA)-129-1 in colon cancer.Methods:The changes of expression and methylation of miRNA-129-1 were analyzed from the methylation, mRNA expression and miRNA expression data of colon cancer in the cancer genome atlas (TCGA) database. The target genes of miRNA-129-1 were predicted from miRwalk 2.0 and TargetScan database. DAVID 6.7 online software was used for gene oncology and Kyoto encyclopedia of genes and genomes enrichment analysis. STRING database was used for protein-protein interaction analysis. TCGA data were applied again to analyze the differential expression and prognosis of key target genes of miRNA-129-1. Paired t test and independent sample t test were used for statistical analysis. The receiver operating characteristic curve (ROC) was used to evaluate the diagnostic value of miRNA-129-1 gene methylation in colon cancer. Kaplan-Meier method and log-rank test were used to analyze the effects of miRNA-129-1 expression on survival. Results:The sequence of miRNA-129-1 among different species was conserved. After all colon cancer samples, and control samples of TCGA database were analyzed, the results showed that compared with those of control samples, the expression of miRNA-129-1 decreased in cancer samples (0.98±0.81 vs. 5.74±0.59), and the methylation levels of cg04524088, cg04840800, cg11364290, cg20734982 and cg24044186 locus of miRNA-129-1 significantly decreased (0.321±0.130 vs. 0.563±0.051, 0.432±0.123 vs. 0.624±0.064, 0.475±0.153 vs. 0.768±0.033, 0.659±0.180 vs. 0.816±0.037 and 0.862±0.096 vs. 0.916±0.019, respectively) in colon cancer tissues, and the differences were all statistically significant ( t=14.95, 11.36, 9.39, 11.74, 5.32 and 3.47, all P<0.01). The results of ROC analysis showed that the methylation levels of the above five locus of miRNA-129-1 gene had high diagnostic efficiency in colon cancer (area under curve=0.946, 0.915, 0.950, 0.758 and 0.667, all P<0.01). The results of survival analysis indicated that low expression of miRNA-129-1 was associated with poor prognosis (hazard ratio ( HR)=0.55, P=0.018). The results of bioinformatics analysis demonstrated that the target genes of miRNA-129-1 were enriched in serine / threonine kinase receptor, mitogen-activated protein kinase and other functional gene clusters closely related to tumor, and there was a complex interaction network among the target genes proteins. The high expression of ephrin type-B receptor2 ( EPHB2) gene, a potential key target gene of miRNA-129-1, was associated with the short overall survival and disease-free survival time ( HR=1.9 and 1.6, both P<0.01). Conclusions:The expression and methylation of miRNA-129-1 play an important regulatory role in the development and development of colon cancer. The methylation of miRNA-129-1 has potential value in the diagnosis of colon cancer, and miRNA-129-1 is an influencing factor for the prognosis of patients with colon cancer. EPHB2 may be a potential key target gene of miRNA-129-1.
