ABSTRACT

Objective To explore the correlation between hyperuricaemia and blood pressure, and blood lipid and glucose. Methods By using simple cluster sampling, 2 branch units from PetroChina Changqing Oilfield Company were selected, and all the 720 subjects with hyperuricaemia (HUA) were assigned to the HUA group; another 620 participants with normal uric acid (UA) level into the normal group. The correlation between blood uric acid and blood pressure,and blood lipid and glucose was assessed by Logistic regression. Results The odds ratio (OR) of those who had 1,2 or 3 abnormal status of hypertension,hyperlipidemia and impaired fasting glucose in the HUA group were much higher than the normal group (OR values were 4. 036,2. 562, and 4. 174, respectively). Logistic regression showed that male, systolic blood pressure ( SBP), GLU, total cholesterol ( TC), triglyceride ( TG), low-density lipoprotein cholesterol (LDL-C) were risk factors of H UA ( OR values were 7. 736,2. 309,1.721,2. 761 and 1. 411,respectively) ,while high-density lipoprotein cholesterol (HDL-C, OR = 0. 211 ) was a protective factor of HUA. Conclusions Gender,blood pressure and blood lipid may have correlation with blood UA. Multiple risk factors should be considered to improve the effectiveness of health education and health promotion.

ABSTRACT

Our previous study demonstrates that hypoxia promotes human bone marrow-derived mesenchymal stem cell (hMSC) proliferation. The aim of the present study was to investigate the gene profile involved in this process by using cDNA microarray. Cultured hMSCs were treated with hypoxia (3% O(2)) for 4 h, 12 h, 24 h, 36 h, 48 h and 72 h, respectively. Then these cells were collected to prepare total RNA. Hypoxia-induced gene expression profile was examined and analyzed by GenePix Pro 4.0 software. Some of cDNA microarray results were confirmed by RT-PCR. Microarray analysis identified that 282 genes expressed differentially, of which most were involved in metabolism. The number of differentially expressed genes at different hypoxia time points was different, and most genes were regulated after 24-hour hypoxia. Among the 282 differentially expressed genes, 4 hypoxia-inducible factor 1 (HIF-1) targeted genes and 10 genes that changed at 3 continuous time points were found. The results obtained indicated that 4 HIF-1 targeted genes, i.e., transforming growth factor beta3 (TGFbeta3), phospho-glycerate kinase 1 (PGK1), insulin-like growth factor binding protein 3 (IGFBP3) and BCL2/adenovirus E1B 19 kDa interacting protein 3 (BNIP3), displayed up-regulated pattern at 36 h under hypoxia. BNIP3 displayed a dynamically up-regulated pattern at 12, 36 and 72 h under hypoxia. However, TGFbeta3 and PGK1 were down-regulated at 72 h. In addition, the gene expressions of adenylate kinase 3-like 1 (HAC), neurofilament light polypeptide 68 kDa (NEFL), N-myc downstream regultated gene 1 (NDRG1), discoidin domain receptor family member 1 (DDR1), tribbles homolog 3 (TRIB3), nucleoprotein (AHNAK) and eukaryotic elongation factor selenocyteine-tRNA-specific (EESTS) were up-regulated. Moreover, the gene expressions of EESTS, NEFL were up-regulated at 5 different time points under hypoxia. Furthermore, it was found that the gene expressions of histone cluster 1 (HIS1) and transferring receptor (TFRC) were down-regulated. These results suggest that the proliferation of hMSCs induced by hypoxia is a complex process in which a number of genes may be involved.

ABSTRACT

To generate recombinant adenovirus expression vector of human Sema4C gene and observe its expression in mouse myoblasts cell line C2C12 for ensuring easy access to investigate the role of Sema4C gene during myogenesis. The recombinant plasmid was packaged and amplified after being transfected in HEK293 cells through Lipofectamine. After infecting C2C12 myoblasts with recombinant adenovirus vector, the adenoviral infection efficiency was determined by confocal microscope which showed that the expression of green fluorescence could be detected at 12h and then reached peak at 24h after recombinant adenovirus infection. The infection efficiency was almost 100% confirmed by FACS examination. Detection of WB indicated that the expression of Sema4C in C2C12 of recombinant adenoviral infection group was significantly higher than that of the control group (P
