Objective To investigate the effect of hyperuricemia(HUA) on inflammation and endothelin-1 (ET-1) production and treatment of Benzbnomanone in hypertensive patients.Methods 90 initial hypertensive patients were enrolled from the inpatient division and clinic of our hospital,60 patients of them were identified HUA,and 30 patients were normal in uric acid as control.All these hypertensive patients with HUA were treated with basic anti-hypertensive drugs,of them 30 patients were additionally treated with Benzbromarone table 50mg for 8 weeks.The levels of inflammation indices and ET-1 were compared between these hypertensive patients with HUA and hypertensive patients with normal serum uric acid,also hypertensive patients with HUA treated with or without Benzbromarone for 8 weeks.Results Compared with the hypertensive patients with normal serum uric acid,levels of ET-1,interleukin-1 (IL-1) and high-sensitive C reactive protein (hsCRP) were higher in the hypertensive patients with HUA.Also,the levels of these indices were positively correlated with the level of serum uric acid [(86.6 ± 4.8) pg/ml vs (82.4 ±6.9)pg/ml; (47.6 ±6.2)mg/L vs (19.1 ±4.1) mg/L; (3.4 ±0.8)mg/L vs (2.9 ± 1.1)mg/L,r =0.81,0.74,0.83,all P ＜ 0.05].Benzbromarone could effectively decrease the levels of ET-1,IL-1and hsCRP in the hypertensive patients with HUA [(49.8 ± 5.0) pg/ml vs (87.5 ± 5.9) pg/ml ; (17.6 ±8.8) mg/L vs (48.2 ± 7.0) mg/L; (1.7 ± 0.7) mg/L vs (3.5 ± 0.9) mg/L,all P ＜ 0.05].Conclusions HUA could increase the levels of inflammation and ET-1,while Benzbromarone effectivelv decreased these changes.Decreasing the level of serum uric acid would retard the process of atherosclerosis in the hypertensive patients with HUA.

ObjectiveTo investigate the effects of Aniracetam on learning and memory dysfunction in mice with cerebral ischemia/reperfusion injury. Methods48 mice were randomly divided into control group, sham operated group, model group and Aniracetam group, with 12 mice each. Mice model of cerebral ischemia/reperfusion injury was established by bilateral common carotid artery blocking. The learning and memory function was tested by Morris water maze.ResultsThe latent period in the model group was longer than that in the normal group and the sham operated group (P<0.05). Aniracetam could shorten the latent period significantly as compared with those in the model group (P<0.05). ConclusionAniracetam has effects in improving learning and memory function in cerebral ischemia/reperfusion injured mice.

Mice model of cerebral ischemia/reperfusion injury was established by bilateral common carotid artery blocking. 7 days before and after operation, the mice in EBH group were injected I.p.with EBH injection 0.15 ml/d, while those in other groups were injected I.p. with saline 0.15 ml/d. The learning and memory function was tested by Morris water maze.Results The latent period in the model group was longer than that in the normal group and the sham operated group (P<0.05). EBH could shorten the latent period significantly as compared with those in the model group (P<0.05).Conclusion EBH can improve learning and memory function in cerebral ischemia/reperfusion injured mice.

Objective To explore the effect of coronary artery bypass grafting(CABG) on left atrial (LA) function by strain rate imaging(SRI). Methods Twenty-three patients with coronary heart disease who underwent coronary artery bypass grafting were involved. SRI was performed on those patients to evaluate LA function quantitatively at baseline (before CABG),and at 1 week, 1 month and 3 months after CABG. Peak strain rate(SR) was measured at each segment (septal, lateral, posterior, anterior, and inferior walls) and mean peak systolic SR (SRs),peak early diastolic SR (SRe) and peak atrial systolic SR (SRa) were calculated by averaging data in each segment. Results Compared with the baseline,LV pre-systolic volume(LAVp), maximal volume (LAVmax), minimal volume (LAVmin), LV active emptying fraction (LAAEF) and passive empting fraction(LAPEF) had on significant differences at 1 week (P >0.05). LAVp,LAVmin,LAVmax and LAAEF decreased gradually after CABG, LAPEF increased gradually after CABG (P <0.05). Compared with the baseline, the peaks of SR curve showed no significant differences at 1 week (P >0.05). Nevertheless,the peaks of SR were increased at systole and early diastole,decreased at atrial contraction at 1 month (P <0.05). Those changes were turned more significantly at 3 months (P 0.01). Left ventricular ejection fraction (LVEF) both increased at 1 month and 3 months,and its changing rate correlated inversely with the changing rate of SRa respectively (r = -0.751, -0.783,all P<0.01).Conclusions LA function is affected by CABG, presented as reservoir and pump functions decreased and conduit function increased. SRI can evaluate the atrial function quantitatively and monitor the changing of LA function dynamically after CABG.

Objective To explore the value of echocardiography in detecting left atrial systolic function in patients with hypertrophic cardiomyopathy(HCM) or hypertensive left ventricular hypertrophy (HLVH). Methods There were 3 groups in this study,the group of HCM, HLVH and control,each group had 30 cases. Left atrial diameter,interventricular septal thickness, posterior left ventricular thickness, peak E and A of mitralis were measured by conventional echocardiography. Left atrial fractional shortening (LAFS) was calculated. Tissue velocity imaging of all patients and controls were accepted in apical two, four and long axis chamber views. Strain rate(SR) imaging was performed on all cases, peak atrial systolic left atrial SR(LASRa) were measured at each segment (septal,lateral, posterior,anterior, and inferior walls of left atrium), mean LASRa was calculated by averaging data in all segments. Results Compared with controls, LAFS and mLASRs of HCM and HLVH were significantly higher ( P ＜0.05). Moreover, LAFS and mLASRs of HCM were significantly higher than HLVH (P ＜ 0.05). mLASRa correlated positively with LAFS of HCM and HLVH respectively ( r =0.81,0.88,all P ＜0.01). Conclusions The change of left atrial function of HCM and HLVH presented as pump function increased.

Objective To explore the changes of left atrial systolic function in patients with coronary heart disease after coronary artery bypass grafting (CABG). Methods Strain rate imaging (SRI) was performed on 23 patients with coronary heart disease before CABG, 1 week, 1 and 3 months after CABG to evaluate left atrial systolic function quantitatively. Results No significant change of left atrial systolic function was detected 1 week after CABG (P＞0.05 ). E/A and LVEF increased, LAFS, AEF and SRa decreased 1 month after CABG compared with those before CABG (P＜0.05). Three months after CABG, changes turned more significantly (P＜0.01). Left ventricular ejection fraction (LVEF) increased 1 and 3 months after CABG, and its changing rate negatively correlated with those of Sra (r=-0.751,-0.783; all P＜0.01). Conclusion Left atrial systolic function is affected by CABG, presenting as decrease of pump function. SRI can be used to evaluate the atrial systolic function quantitatively and monitor the changing of left atrial systolic function dynamically after CABG.

ObjectiveTo evaluate left atrial function in patients with dilated cardiomyopathy (DCM)by echocardiography.MethodsThere were 31 patients with DCM and 30 controls in this study.Left atrial diameter (LAD),left ventricular diameter (LVD) were measured by M-mode in parasternal long-axis view.Mitral flow parameters including peak velocities during early diastole (E) and late diastole (A) were measured by pulsed-wave Doppler echocardiography,and the E/A ratio was calculated.Left ventricular ejection fraction (LVEF) was measured with Simpson′s method on the 2-chamber (Ap2c) and 4-chamber (Ap4c) views.Strain rate (SR) imaging was performed on all cases.Peak SR was measured at each segment (septal,lateral,posterior,anterior,and inferior walls) and mean peak systolic left atrial SR (mLASRs),mean peak early diastolic left atrial SR (mLASRe) and mean peak atrial systolic left atrial SR (mLASRa) were calculated by averaging the data in all segments.ResultsCompared with controls,LAD and LVD were significantly increased ( P ＜0.01 ),the E/A ratio had no significant changes ( P ＞0.05).LVEF and left atrial fractional shortening (LAFS) turned lower,mLASRs,mLASRe,and mLASRa of DCM decreased significantly ( P ＜ 0.05).mLASRa of DCM correlated positively with LAFS ( r =0.79,P ＜ 0.01 ).ConclusionsThe left atrial function of DCM decreased,including the reservoir,conduit and pump function.Echocardiography could evaluate the left atrial function of DCM quantitatively.
