ABSTRACT
Objective Toinvestigate the changes of liver and kidney function and morphology of the renal artery of the metabolic syndrome (MS) rats.Methods The rats were respectively fed with ordinary or high-fructose diet for 10 weeks,and then took the blood and anatomical observation,to explore the changes of liver and kidney function and morphology of the renal artery of the rats.Results The serum levels of ALT,AST,UA,BUN,CR in the control group and MS group were gradually increased with the feeding time.But those in MS rats were significantly increased than the control rats.MS rats showed dysfunction of liver and kidney,which similar to the clinical MS cases.Compared with the control group,the renal artery of MS rats had the same pathological changes as MS cases,presented with intima uneven thickening and structural disorder,medial smooth muscle cells hyperplasia to intimal,the internal elastic membrane with different degrees of damage and fracture,the film elastic fibers thickening and structural disorder,smooth muscle cell proliferation apparently,medial obvious thickening.Conclusion MS rats have mild dysfunction of liver and kidney and abnormal changes in intima and tunica media of renal artery.
ABSTRACT
Objective To investigate the effects and mechanisms of rosiglitazone on the expressions of nuclear factor-κB and matrix metalloprotease (MMP-9) in peripheral blood monocyte-derived macrophages (MDMs) in patients with coronary heart disease. Method This was a clinical case-control study. Forty-eight actue coronary symdrome (ACS) patients (ACS group), and 20 patients with stable angina (SA) (control group) were collected. They were performed coronary arteriography in the Department of Cardiology of the Second Xiangya Hospital from March to April in 2007. Exclusion criteria included acute infection, trauma or surgery patients within four weeks, cerebral vascular accident, liver and kidney dysfunction, cancer, and so on. The peripheral blood mononuclear cells were isolated and transformed into MDMs with macrophage colony-stimulating factor treatment. The transformed MDMs were randomly assigned into subgrougs and incubated with 0 /μmol/L, 1 μmol/L, 10 μmol/L, 20 μmol/L of rosiglitazone respectively. The expressions of PPAR-γ mRNA, MMP-9 mRNA were determined by RT-PCR and nuclear factor-κB P65 (NF-KB P65) expression by immunohistochemistry. Multiple comparisons were examined for significant differences using analysis of variance (ANOVA). Results The basal expression of PPAR-y mRNA was lower, in contrast, the levels of NF-KB P65 and MMP-9 mRNA were higher in ACS group than control group. PPAR-γ mRNA expression were significantly upregulated in both ACS and control groups with rosiglitazone treatment. PPAR-γ mRNA expression was positive correlation, while the expressions of MMP-9 mRNA were negative correlation with the rosiglitazone concentration in the ACS group. Rosiglitazone inhibited the expression of NF-KB in a concentration-independent manner in ACS and control groups. Conclusions The expression of PPAR-y mRNA is inhibited, while the activity of NF-KB and expression of MMP-9 mRNA are enhanced in MDMs of ACS cases. Rosiglitazone intervention may inhibit NF-KB activity and MMP-9 expression by upregulation of PPAR-y expression in MDMS of patiens with ACS.
ABSTRACT
@#Objective To observe the protective effect of spironolactone on heart of hypertensive SD rats.Methods 30 male SD rats were randomly divided into the control group,hypertensive group(HS group),low spironolactone dose group(HSL group)and high spironolactone dose group(HSH group).The animals except the control group were treated with L-NAME 50 mg/kg/d.Then the animals of the HS group were fed with 1% sodium chloride water solution.Those of the HSL and HSH groups were treated same but the former added with spironolactone 20 mg/kg/d,the later added with spironolactone 100 mg/kg/d.8 weeks late,the animals were killed and hearts were taken out to observe following items:myocardial cross-sectional area,ratio of per-arteriolar fibrous area/arteriolar luminal area of arterioles,ratio of collagen area/total myocardial area,myocardial necrosis and inflammation.Results The myocardial cross-sectional areas in the HS group were significantly more than those in other 3 groups(P<0.01).Collagen ratios of the HS group were significantly higher than others(P<0.01).The ratios of arteriolar wall area versus luminal area in the HS group were significantly higher than those of control and HSH groups(P<0.01).Myocardial injuries in the HS group were more severe than those of other 3 groups.There were no differences between HSL and HSH groups.Conclusion Spironolactone has protective effect on heart of hypertensive SD rats.
ABSTRACT
Objective To investigate the role of Shenqihuang steady plaque caps (SQH) and simvastatin on stabilization of atherosclerosis plaque in rabbits whit atherosclerosis (AS). Methods Forty-five rabbits were randomly divided into five groups: normal food group (A), instability plaque group (B), SQH group (C), simvastatin group (D), SQH add simvastatin group. A group was fed with common feeds, and B, C, D, E groups were given high cholesterol feeds. An atherosclerotic rabbit model was established by feeding high cholesterol diet supplemented for 12 weeks in B, C, D, E groups. Then C, D, E groups received corresponding drugs. At the end of 24~(th) week, the drug were injected into the aortic segments rich in plaque. Two weeks later, the concentration in serum of lipids, vascular cellular adhesion molecule-1 (VCAM-1), intercellular cellular adhesion molecule-1 (ICAM-1) and high sensitivity C reaction protein (hs-CRP), and area of plaque, the thickness of endomembrane, ttmica media, fibrous cap were detected. Results Compared with B group, the concentration of VCAM-1, ICAM-1, hs-CRP and area of plaque, the thickness of endomembrane, tunica media in C, D and E groups were lower significantly, the thickness of fibrous cap was thicker significantly (P

Objective To investigate the effects of angiotensin Ⅱ type 1 receptor(AT 1R) antagonist,TCV-116,and angiotensin-converting enzyme inhibitory(ACEI),Delapril on neointimal formation after carotid balloon injury in rats. Method TCV-116 and Delapril were administered p.o for 3 weeks(1 weeks before and 2 weeks after carotid balloon injury) in SHR.Neointimal formation of carotid artery was examined.Results Compared with the control group,neointima/media area ratio was significantly reduced(48 3% and 45 5% respectivity,P
ABSTRACT
Objective To investigate the effect of Xuefuzhuyu granule combined Irbesartan in reversing the carotid vascular remodeling of essential hypertension(EH) patients. Methods 61 EH patients were enrolled in this study. 29 cases of EH were treated with Irbesartan, 32 cases were treated with Xuefuzhuyu granule and Irbesartan, and 28 normotensive subjects served as control. Color dopplor ultrasound were adopted to measure IMT and LD of carotid. Results After treated for 9～12 months, the IMT and IMT/LD in EH patietns treated by Xuefuzhuyu granule and Irbesartan significantly decreased than those in EH patients treated only by Irbesartan. Conclusion Xuefuzhuyu granule was beneficial to reversing the carotid vascular remodeling in EH patients.
