The aim of this study is to clarify whether edaravone postconditioning had protective effect against renal ischemia/reperfusion injury and to compare the protective effect between ischemic postconditioning and edaravone postconditioning. Rats were subjected to 45 min ischemia followed by 24 h reperfusion. The rats were randomly assigned to seven groups: a sham-operated control group, an ischemia/reperfusion group, an ischemic postconditioning group, a normal saline vehicle postconditioning group and an edaravone postconditioning (1, 3, and 6 mg x kg(-1)) group. Renal function was assessed by serum creatinine and BUN concentration, while histological damage of renal tissue was assessed with HE staining. MDA content and SOD activity of renal tissue were determined. TUNEL staining was performed to analyze the apoptosis of the tubular epithelial cells, the protein level of Bcl-2 and Bax in renal tissue was examined by Western blotting. Compared to the ischemia/reperfusion group, edaravone postconditioning significantly decreased serum creatinine and BUN concentration, and ameliorated histological damage of renal tissue. MDA was less after 24 h reperfusion in the edaravone postconditioning group than that in the ischemia/reperfusion group, consistent with an increase in SOD activity. In addition, edaravone postconditioning decreased TUNEL-positive cells and Bax expression, and increased Bcl-2 expression. Results detected in the edaravone postconditioning group showed no significant difference from the ischemic postconditioning group. Edaravone administered during the last 3 min of ischemia, prior to reperfusion induces a pharmacological postconditioning in vivo against renal ischemia/reperfusion injury in rats. This protection is similar to that observed with ischemic postconditioning.

Objective To analyze and discuss the value and significance of coronary artery bypass grafts in the same period of heart valve replacement in the process of the coronary heart disease with heart valve disease treatment, in order to improve the effect of treatment and reduce the incidence of adverse events. Methods 60 cases with coronary heart disease with heart valve disease , which admitted in our hospital during February 2013-February 2015, were selected as the research objectaccording to random number table method and divided into the-experimental group and the control group , each group of 30 cases according to the principle of double blind control. The experimental group was given the coronary artery bypass grafts in the same period of heart valve replacement and the control group was given the coronary artery bypass grafts without heart valve replacement. The curative ef-fects of different schemes and effects on cardiac function after surgery of the two groups were compared. Results After statistical analysis found thatthe observation indexes of the control group was significantly increased compared with the experimental group, the difference was significant statistically significant (P<0.05). The postoperativecar-diac function indexes of the experimental group was significantly improved then control group , the difference was significant statistically significant (P<0.05). Conclusion Coronary heart disease with heart valve disease in the process of treatment can also take heart valve surgery combined coronary artery bypass surgery. By preoperative and postoperative symptomatic treatment, intraoperative protect myocardium, can effectively prevent and reduce the op-eration of various complications, which is worthy of clinical popularization and application.

Aim To investigate the effects of ginaton on tubular cell apoptosis in a rat model of renal ischemia/reperfusion(I/R) injury.Methods The model of bilateral post-ischemic renal injury was established by clamping renal pedicles for 45 minutes.To explore the effects of ginaton on activation and expression of JNK and c-Jun,p-JNK1/2,JNK,p-c-Jun,c-Jun were examined by Western blotting.Apoptosis of renal tubular epithelial cells was assessed by terminal deoxynucleotidyl transferase mediated dUTPnick end labeling(TUNEL) and flow cytometric analysis.Results Phosphorylation levels of the JNK and the c-Jun were significantly increased at 20 min after renal I/R injury.This corresponds to a significant increase of apoptotic tubular cells induced by renal I/R injury.Ginaton attenuated the increased phosphorylation of p-JUK at 20 min(vs I/R 20 min,P

Objective To observe the influences of Yangxinshi pill on ET, NO, CRP in patients with angina pectoris belonging to manifestation of Qi-deficiency and blood stagnation. Methods 78 patients with angina pectoris were randomly divided into two groups. 40 patients in treatment group were treated with Yangxinshi pill, 4 pills once, three times a day 8 weeks. 38 patients in control group were treated with isosorbide mononitrate 8 weeks. The symptoms and the ET, NO, CRP level before and after treatment were recorded. Results Obvious drop of ET, NO, CRP were observed after treatment in the treatment group. The level of ET was reduced from (67.47?15.72)pg/mL to (37.97?7.82) pg/mL. The level of NO was increased from (78.24?13.81)?mol/mL to (96.25?12.72)?mol/mL. The level of CRP was reduced from (5.31? 2.02)mg/L to (3.42?2.17) mg/L. There was a significant difference between the two drugs (P 0.05). The total efficacy rate in improving symptom was 95%. There was a significant difference between the two drugs (P

Objective To investigate the level of serum retinol-binding protein 4 (RBP4) and related factors in chronic hepatitis C (CHC). Methods Fifty-six patients with CHC (CHC group) and 35 healthy volunteers (control group) were selected. Serum RBP4 level was measured by ELISA method.Fasting blood glucose ( FBG ), triglycerides (TG), total cholesterol ( TC ), alanine aminotransferase (ALT),γ-glutamyl transpeptidase (γ-GT) were measured, HCV-RNA level was tested by qualitative polymerase chain reaction(q-PCR). Results There were no significant difference in FBG, TC,TG, γ-GT between two groups (P > 0.05 ). Serum RBP4 level in CHC group [(33.38 ± 6.43 ) mg/L] was higher than that in control group [(26.11 ± 3.35) mg/L](P< 0.01),the CHC patients with ALT normal (26 cases) had significantly higher RBP4 level [( 38.96 ± 4.09) mg/L] compared with ALT abnormal [30 cases, ( 28.53 ± 3.43 ) mg/L](P < 0.01 ). ALT level was negative with RBP4 in CHC group (r = -0.6368, P < 0.05 ). Conclusion Serum RBP4 level is significantly associated with CHC and negatively correlated with ALT level,but not associated with FBG, TC,TG, γ-GT and HCV-RNA.

Objective:To investigate the effect of silver diamine fluoride(SDF)on the bonding strength between dentine and glass ion-omer cement(GIC).Methods:1 2 extracted sound molars were prepared into dintine samples and distributed into sound dentine group and demineralized dentine group.According to the treatment methods,the samples in each group were respectively divided into 3 sub-groups:A(control group),B[coated with 38% Ag(NH3 )F2 ]and C(SDF treatment with additional lighting-curing)(n =20).Then a hand-mixed conventional glass ionomer cement Fuji IX was placed on the dentine surface.After 24 h,micro tensile bond strength test and scanning electron microscope (SEM)analysis were conducted.Results:The bonding strength of demineralized dentine was higher than that of sound dentine(P <0.01 ).SDF with additional lighting-curing treated dentine showed a higer bonding strength value than only SDF treated dentin(P <0.01 ).Conclusion:SDF may improve the bonding between dentine and GIC.

The clinical features of 120 severe cases with hand-foot-mouth disease (HFMD) were retrospectively analyzed compared with those of the regular cases. Clinical data showed that the age of mostsevere cases ranged from 1-3 years. Sustained high fever ( 55% ) , hypertension ( 40% ) , fewer rash (73.3%) were important clinical features. Lethargy, somnolence or restlessness (70. 8% ), vomiting (30. 8% ) were early signs of central nervous system ( CNS) ; and the CNS involvement in severe cases was characterized by body trembling or muscle spasm (80% ). High white cell count(75. 8% ) and high blood glucose levels(32. 5% ) were important makers to diagnose the severe HFMD at early stage. There were significant differences in presentation of above features between severe cases and regular cases of HFMD ( P < 0. 01 or P < 0. 05 ) . Early treatment with mannitol, gamma globulin and glucocorticoids were effective, no death was reported and no side effects were found in this case series.
