Objective To investigate whether intensive atorvastatin treatment in patients after percutaneous coro-nary intervention ( PCI) could decrease the effect of contrast medium on kidney function and the incidence of con-trast-induced acute kidney injury( CI-AKI) . Methods A total of 128 patients with PCI were randomly divided into two groups:the enhanced treatment group (n=64) and the control group(n=64). The enhanced treatment group received 80 mg atorvastatin at 12~24 h before PCI and 24,48 h after PCI. The control group was given 20 mg ator-vastatin respectively before and after PCI. The primary end point was the incidence of CI-AKI. Serum creatinine (Scr), cystatin C, glomerular filtration rate(eGFR), urinary albumin and urinary β-2 microglobulin levels were observed at 24 h before PCI and 24, 48, 72 h after PCI. Results In the enhanced treatment group 3. 1 % (n=2) of patients developed CI-AKI versus 4. 7 % (n=3) in the control group, without statistical difference (P=1.00). There was no significant difference between two groups in postoperative Scr, cystatin C, eGFR, urinary al-bumin, urinary β-2 microglobulin and creatine kinase(CK). Three days after the operation, alanine aminotrans-ferase ( ALT) elevated in two groups, and aspartate aminotransferase ( AST) increased in the enhanced treatment group (P<0. 05), but they were all in the normal range. Conclusion There has been no significant difference in decreasing the incidence of CI-AKI and the damage of contrast medium on renal function between the enhanced treatment group and the control group before PCI.

Objective To study on transcatheter closure of membranous ventricular septal defect (VSD) with pseudoaneurysm by patent ductus arteriosus(PDA) occlusion devices in children and summarize the skill and clinical experience. Methods The study included 20 membranous VSD cases in children.According to the finding of the left ventricular angiography, various kinds of the PDA occlusion devices was implanted. The mean diameter of the waist of the occluder was ( 10.4 ± 2.6) mm. Examination by transthoracic echocardiography (TTE) immediately and left ventricular angiography after the occluder was implanted 15minutes later to evaluate the efficacy. Results In the 20 patients, one of the Ⅳ type VSD patient was quitted because of the significant residual shunts(≥2 mm). Slightly residual shunts ( < 2 mm) was found in one Ⅲ type VSD patient with multi-outlet. And disappeared in 1 month after the procedure, which VSD patient was confirmed by TTE. Thirteen cases were normal by EKG examination (or the same before procedure).Incomplete right bundle branch block was found in 4 cases. First degree atrioventricular block was found in 1 case and paroxysmal junctional tachycardia was found in 1 case. All of them were recovered in 1 week.Conclusions Transcatheter interventional therapy with PDA occlusion devices for membranous VSD with pseudoaneurysm is safe and effective. The key of the procedure is to select suitable occluder and suitable position to plant them according to the membranous morphologic characteristics,size and position of the pseudoaneurysm. It is a facultative method for transcatheter therapy this kind of congenital heart disease.

Objective To evaluate the correlation between seram interleukin-10 (IL-10) and testosterone with coronary heart disease (CHD). Methods 387 patients were divided into CHD group (n = 239) and control group ( n = 148 ) according to the results of coronary angiography. CHD patients were divided into subgroups accord-ing to the numbers, Gensini score of lesions in the coronary arteries and clinical severity ( statue of stable coronary artery disease, unstable angina or acute myocardial infarction). Serum IL-10 and testosterone levels were measured by ELASA. Logistic regression and partial correlation were used to evaluate the correlation of serum IL-10 and testoster-one with CHD. Results IL-10 was significantly lower in the CHD group than in the control group[ (39.08 ± 14.22) ng/L vs (49.27 ± 24.67)ng/L, P < 0. 001 ]. The partial correlation analysis results in subgroups showed that the correlation coefficient of IL-10 with number of lesions,gensini score and clinical severity of CHD was - 0.25, P < 0.001, -0.25 ,P <0.05 and -0.25 ,P <0.001 ,respectively. Serum testosterone had no difference in control group and CHD group (P >0.05 ). Logistic regression analysis found that only smoking (OR = 3.79,95% CI 2.09~ 6.84,P<0.01) ,diabetes mellitus (OR =2.48,95% CI 1.05 ~5.88,P <0. 05) ,apoB ( OR = 14.3,95% CI 4.29~46.61 ,P <0.01 ) and IL-10 ( OR =0.74,95%, CI 0.57~0.89 ,P <0.01 ) entered the model. Conclusions Serum IL-10 is not only significantly correlated with CHD but also with its severity. IL-10 is an independent pro-tective factor for CHD.
