The effects of hepatocyte growth factor(HGF) on the secretion of vascular endothelial growth factor(VEGF) in cultured bovine coronary artery endothelial cells(BCAEC), bovine coronary artery smooth muscle cells(BCASMC) and mouse cardiomyocytes were observed in vitro . The concentrations of VEGF in BCAEC control and HGF group at 12h were 10.51?2.90pg/ml and 9.31?2.78pg/ml, respectively. The concentrations of VEGF at 12h in BCASMC control and HGF group were 3.35 and 3.93 times of that at 3h respectively, the concentration of VEGF at 3h and 12h in BCASMC HGF group was 2.06 and 2.42 times respectively, of that in control group. The concentrations of VEGF at 12h in cardiomyocyte control and HGF group were 5.43 and 4.09 times, respectively, of that at 3h, and the concentrations of VEGF at 3h and 12h in cardiomyocyte HGF group was 2.74 and 2.06 times, respectively, of that in control group. These results indicated that BCAEC, BCASMC and mouse cardiomyocytes could secrete VEGF, and HGF could promote VEGF secretion in BCASMC and cardiomyocytes, but not in BCAEC.

The effects of vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) on proliferation of bovine coronary artery endothelial cells (BCAEC) and smooth muscle cells (BCASMC) were studied in vitro. BCAEC and BCASMC were isolated and cultured and divided into control group, VEGF (50ng/ml) group and HGF (50ng/ml) group. Cells proliferation was measured using MTT method. The results showed that the OD values of control, VEGF, and HGF group in BCAEC cultures were 0.23?0.02, 0.58?0.10, and 0.42?0.12, respectively, and those in BCASMC were 0.31?0.08, 0.45?0.09, and 0.40?0.11, respectively. The proliferation ratios of BCAEC and BCASMC induced by HGF were 152.2%?33.8% and 45.2%?25.3%, respectively, and that by VEGF were 82.6%?18.7% and 29.0%?20.4%, respectively. The results suggested that HGF could promote proliferation and migration of BCAEC and BCASMC, while VEGF could promote proliferation of BCAEC but not BCASMC. The effect of HGF on BCAEC was stronger than that on BCASMC, and the induction strength of HGF was higher than VEGF.

Objective To discuss hemorheologic changes and hepatic function in patients with chronic hepatitis B(CHB)and its correlation with HBV genotype.Methods Relative index of hemorheologic changes,ALT,HBV-DNA and HBV genotype were examined in 96 CHB patients and 24 healthy control people.The results underwent correlation analysis.Results Low-shear blood viscosity and RBC aggregation index were significantly higher in CHB patients than those in the healthy control people(P＜0.05).Low-shear blood viscosity and RBC aggregation index were significantly higher in CHB patients with abnormal ALT than those CHB patients with normal ALT and the healthy control people(P＜0.05).No statistical difference was seen when CHB patients with normal ALT were compared with the healthy control people and patients with positive HBV-DNA were compared with patients with nesative HBV-DNA(P＞0.05).No statistical difference was seen in hemorheologic changes in CHB patients with different genotype(P＞0.05).Conclusions Microcirculation disorder of CHB patients is correlated with damage degree of hepatic function.Hemorheologic changes are not correlated with HBV-DNA and HBV genotype,so it can be a relatively independent index for clinical evaluation of disease.

Objective：To study the mental health status of heroin addicts and their need for psychotherapy after detoxification. Methods：The mental health of 83 heroin addicts and 70 normal subjects were assessed by SCL-90, Social Support Rating Scale , EPQ, SAS and SDS. Results：As compared to normal controls, heroin additions were found to score higher on various mental health measures, including SCL-90 total and factor scores, the N score of EPQ, as well as total scores on SAS and SDS. The social support in heroin addicts scored lower than normal subjects. Conclusion：Heroin addicts have severe psychological problems, which warrant long-term psychological rehabilitation after detoxification.

BACKGROUND: Studies have demonstrated that intermittent high glucose can have a more severe impact on vascular endothelial function in comparison with persistent hyperglycemia.OBJECTIVE: To investigate the effect of intermittent high glucose on the proliferation and apoptosis of endothelial progenitor cells (EPCs) from human peripheral blood in vitro as well as the production of malondialdehyde (MDA) and antioxidant. METHODS: Total mononuclear cells were isolated from human peripheral blood by Ficoll density gradient centrifugation and then the cells were placed on fibronectin-coated culture dishes. After 7 days of culture, the adherent cells were identified as EPCs by laser scanning confocal microscope. The cells were synchronized and then stimulated with glucose 5.5 mmol/L (normal control group), 20 mmol/L (constant high glucose group), and 5.5/20 mmol/L (intermittent high glucose group, 5.5 and 20 mmol/L glucose culture solution was changed every 8 hours) for 72 hours. EPCs proliferation and apoptosis was measured by MTT assay and flow cytometry, respectively. The content of MDA and the activity of superoxide dismutase (SOD) in culture solution were detected with colorimetry.RESULTS AND CONCLUSION: After EPCs were exposed to constant high glucose (20 mmol/L) and intermittent high glucose (5.5/20 mmol/L) for 72 hours, proliferated cells were significantly reduced and the apoptosis rate was significantly increased compared with those exposed to normal glucose (P < 0.01). Furthermore, there was a significant increase in MDA contents as well as a significant reduce in SOD activities in the constant high glucose and intermittent high glucose group (P < 0.01), especially in the latter group. These findings indicated that both intermittent high glucose and constant glucose could inhibit the proliferation and promote the apoptosis of EPCs; however, intermittent high glucose appears to worsen the effects on EPCs. This is maybe due to the increased oxidative stress.

Objective To explore the titre of serum anti-phospholipase A2 receptor antibodies (anti-PLA2 R antibodies) detected by the enzyme-linked immunosorbent assay (ELISA) to provide a more specific serological index for clinical diagnosis and disease judgment of membranous nephropathy (MN).Methods Thirty-four cases of MN confirmed by kidney biopsy ,32 inpatients with autoimmune diseases ,nephrotic syndrome and renal insufficiency in the nephrology department of our hospital and 12 persons un-dergoing physical examination were selected.The serum was collected for detecting anti-PLA2 R antibodies level.Then its diagnostic performance for diagnosing MM was analyzed by combining with serum TP ,ALB ,IgG ,IgA ,IgM ,C3 and C4 indicators.Results The medians of anti-PLA2 R antibodies titres in the MN group ,disease control group and healthy control group were 22.1 ,2.0 ,2.0 RU/mL respectively ,which had statistical difference between the MN group and other two groups (P<0.05).Seventeen cases of anti-PLA2R antibodies positive were in the MN group(positive rate50% )and 17 cases were negative,the disease control group and healthy control group all were negative.Its specificity and positive predictive value were 100% ,TP ,ALB and IgG had statistical difference between the MN group with the disease control group and healthy control group (P<0.05);the relative coefficients of anti-PLA2 R antibodies with TP ,ALB and IgG ,IgA ,IgM ,C3 and C4 were in turn -0.382 ,-0.344 ,-0.502 ,-0.295 ,0.062 , 0.005 and 0.241 respectively ,anti-PLA2R antibodies were negatively correlated with TP ,ALB ,IgG and IgA(P<0.01) ,positively correlated with C4(P<0.05) and had no relation with IgM and C3(P>0.05).Conclusion Anti-PLA2 R antibodies have higher specificity for the diagnosis of MN and can serve as the necessary and specific serologic detection indicator in the patients unable to conduct renal biopsy.Quantitative detection helps to condition judgment.
