Objective To observe the effect of muscone on the blood-brain barrier and neuropathological changes after complete cerebral ischemia/reperfusion of rats.Methods The global cerebral ischemia/reperfusion injury model was established by the four-vessel occlusion(4VO) method,and then the model animals were given high-,middle-and low-dose muscone.Meanwhile,sham-operation group,model group,and positive control group were also set up.The rats neuroethology behavior,and the contents of superoxide dismutase(SOD),malondialdehyde(MDA) and excitatory amino acid(EAA) in ischemic brain tissue were examined.Results Muscone increased SOD content,lowered MDA content,reduced the increase of EAA content caused by ischemia and hypoxia,and inhibited the excitatory neurotoxicity caused by EAA.Conclusion Muscone has obvious protective effect on rats with complete cerebral ischemia/reperfusion injury.

BACKGROUND:Previous studies have shown that continuous administration of 1×107 of bone marrow mesenchymal stem cel s can induce immune tolerance in rats undergoing kidney transplantation, but it is not yet found clinical y that curcumin exerts an on immunomodulatory effect on kidney transplantation.
OBJECTIVE:To investigate the effects of different concentrations of curcumin on bone marrow mesenchymal stem cel s-induced immune tolerance in rats after kidney transplantation.
METHODS:Rat model of kidney transplantation was made, and rat models were randomly divided into four groups:transplantation group with no treatment;bone marrow mesenchymal stem cel s group (cel group) injected with 1×107/kg bone marrow mesenchymal stem cel s via the left iliac vein (before peritoneal suture) and tail vein (from the 2nd day) for 10 days;bone marrow mesenchymal stem cel s+low/high dosage of curcumin groups (low/high dosage curcumin groups) injected intragastrical y with 2 or 10 mg/kg curcumin combined with injection of bone marrow mesenchymal stem cel s for 10 days. Transforming growth factor-β1 protein expression in the kidney tissues was examined by immunohistochemical staining. The concentrations of interleukin-2 and interleukin-6 in serum were detected by ELISA assay.
RESULTS AND CONCLUSION:After kidney transplantation, the protein expression of transforming growth factor-β1 in renal tubular epithelial cel s and renal interstitial cel s as wel as the concentrations of interleukin-2and interleukin-6 in serum were significantly higher in the transplantation group than the other groups (P<0.05). Compared with the cel transplantation group, the protein expression of transforming growth factor-β1 as wel as the concentrations of interleukin-2 and interleukin-6 reduced significantly in the low/high dosage curcumin groups (P<0.05). These findings indicate that simultaneous administration of curcumin and bone marrow mesenchymal stem cel s can effectively inhibit immune rejection reaction and improve renal function in rats after kidney transplantation.

Objective To investigate the relationship between H-type hypertension and unstable angina (UA).Methods Totally 147 elderly inpatients with hypertension and angina in our hospital were selected.Patients were divided into H-type hypertension group [n=72,serum homocysteine (Hcy) level ≥10 μmol/L] and primary hypertension group [n=75,serum homocysteine (Hcy) level <10 μmol/L].All patients underwent coronary angiography.Serum Hcy level was measured by enzyme method and compared between groups.Results There were statistical differences in the UA incidence,Gensini's score and high sensitive C-reactive protein (hsCRP) level between the H-type hypertension group and primary hypertension group [(44.4% (32/72) vs.12.0% (9/75),(44.2± 21.3) vs.(31.9±18.4),(4.3±2.1) μg/L vs.(2.0±1.9) μg/L,respectively,all P<0.01].Serum Hcy level in H-type hypertension group was higher during UA attack than during UA remission [(22.2±7.1)μmol/L vs.(13.7±3.7)μmol/L,P< 0.01].Serum Hcy level during UA attack was increased in H-type hypertension group than in stable angina group [(22.2±7.1)μmol/L vs.(12.0± 4.2) μmol/L,P < 0.01].Serum levels of Hcy,total cholesterol and low density lipoprotein cholesterol in primary hypertension group were higher in UA patients than in stable angina patients [(8.9±2.2)μmol/L vs.(6.6± 1.2)μmol/L,(6.9±0.7)mmol/L vs.(4.5±0.5)mmol/L,(4.6±0.8)mmol/L vs.(2.7 ± 0.6) mmol/L,respectively,P< 0.01 or P<0.05].Logistic regression analysis showed that H-type hypertension was the independent risk factor for unstable angina in the elderly (OR =5.691,P < 0.01).Conclusions H-type hypertension is closely correlated with unstable angina,which is the independent risk factor for unstable angina in the elderly.Serum Hcy level has significant correlation with coronary atherosclerotic plaque stability and the severity of coronary artery disease.
