Objectives To study the effect of ubiquitin proteasome inhibitor bortezomib on apoptosis and Caspase-3 expression in human umbilical arterial vascular smooth muscle cells. Methods Human umbilical artery vascular smooth muscle cells were cultured in vitro. Different doses of bortezomib (0, 4, 10, 40nmol/L) were used to treat cell. Cell proliferation activity were detected by using CCK8 method. Western Blot assay was used to measure the expression of Pro-caspase-3 and Cleaved-PARP protein. Morphology of cells in different groups are observed by confocal microscopy and apoptosis rate were detected by flow cytometry analysis. Results Bortezomib inhibits proliferation activity of vascular smooth muscle cells. With increasing of drug concentration and treating time, cell viability are reduced (P < 0.01). Cells treated with different concentrations bortezomib for 48 h showed increased apoptosis rate (P < 0.01), decreased pro-caspase-3 protein expression and increased cleaved-PARP protein expression (P < 0.01). Laser confocal microscope found that with the increase of drug concentration, the number of apoptotic cells showed an upward trend under per high-power vision. Conclusion The ubiquitin proteasome inhibitor bortezomib may decrease the expression of pro-caspase-3 and increase Cleaved-PARP expression in human umbilical artery vascular smooth muscle cells. Additionally , it could induce apoptosis in a dose-dependent manner.

Objective To determine whether sulfasalazine stimulates hepatic stellate cell (HSC-T6) apoptosis and its possible mechanism. Methods CCK-8 assay, acridine orange/ethidium bromide(AO/EB) and Annexin Ⅴ FITC/PI were used to determine cell growth and cell apoptosis. The expression of NF-?B P65, phospho-IKK and phospho-I?B was detected by Western blotting. The nuclear translocation of HSC-T6 P65 was observed with laser confocal microscopy. Results Sulfasalazine displayed a strong growth inhibition and promoting apoptosis effect on HSC-T6 cells in a dose and time-dependent manner. Sulfasalazine, but not 5-aminosalicylic acid or sulfapyridine, inhibited the activation of NF-?B by down-regulating the expressions of P-IKK, P-I?B and the nuclear translocation of P65. Conclusion Sulfasalazine can inhibit NF-?B activity and promote apoptosis in HSC-T6 cells, where the Rel/NF-?B/I?B/IKK pathway plays an important role in HSC survival.

Objective: To investigate the protective effect of Feikang Granules (FK) on endodermis scathe of pulmonary vascular in rats with hypoxia induced pulmonary hypertension (HPH). Methods: Hypoxia with intravenous injection FeCl 3 was used to establish model rats with HPH. Hypoxia rats were treated with FK for seven days after hypoxia everyday. Plasma endothelin (ET), superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione peroxidase (GSH PX) in serum were inspected. Results: (1) Those indexes were higher remarkably than control group and showed that the level of series enzyme concerned with oxidation reaction was in unbalance. Pulmonary hypertension and endodermis scathe of pulmonary vascular had happened. (2) The level of ET, MDA, SOD and GSH PX decreased significantly in the treated group. It indicated that FK could inhibit HPH and improve the pathological changes such as endodermis scathe, the unbalance of series enzyme concerned with oxidation reaction. Conclusion:Feikang Granules may partly prevent the development of HPH and endodermis scathe of pulmonary vascular.

To investigate the relationships among plasma secreted frizzled-related protein ( sfrp) 5 level and body fat parameters, glucolipid metabolism, insulin resistance index, and inflammation. 89 subjects with normal glucose tolerance(NGT) and 87 patients with type 2 diabetes mellitus (T2DM) were enrolled and each group was divided into no-obese and obese subgroups. Obesity was defined as body mass index ( BMI)≥25 kg/m2 according to the World Health Organization -Western Pacific Region diagnostic criteria ( 2000 ) . Body fat parameters were measured and BMI, waist-hip ratio were evaluated, meanwhile, the levels of blood glucose-lipid parameters and fasting insulin were also determined. Insulin resistance index ( IR) was assessed by homeostasis model assessment ( HOMA) . The concentrations of plasma sfrp5 and interleukin 6 were detected by enzyme-linked immunosorbent assay. Plasma sfrp5 level in T2DM group was significantly lower than that in NGT group [(8. 35±3. 38 vs 11. 35±3. 69)ng/ml, P<0. 01]. The levels of plasma sfrp5 in subjects with obesity were also lower than those in subjects with no-obesity in both NGT and T2DM groups [(9. 46±2. 70 vs 13. 12±3. 62)ng/ml and(6. 70±2. 34 vs 10. 12±3. 45) ng/ml, both P<0. 01]. Plasma concentrations of sfrp5 in T2DM-obese group were significantly lower than that in NGT-obese group(P<0. 01). Correlation analysis showed that plasma sfrp5 levels were negatively correlated with waist-hip ratio, HbA1C, fasting insulin, triglycerides, waist circumference, fasting plasma glucose, interleukin 6, natural logarithm of HOMA-IR [ln(HOMA-IR)], and BMI(P<0. 01 or P<0. 05). Multiple linear regression showed that ln(HOMA-IR), BMI, triglycerides were independent related factors in influencing the levels of plasma sfrp5 (r2=0. 216, 0. 177, 0. 113, all P<0. 05). Plasma sfrp5 levels were decreased in obesity and T2DM subjects and were correlated with body fat disposition, glucose-lipid metabolism, insulin resistance and inflammation. Lack of sfrp5 may contribute to the pathophysiology of obesity and T2DM.
