AimThe effect of herbal tongxinluo on the thrombus formation and neointimal hyperplasia of the balloon injured rabbit abdominal aorta and iliac artery was observed. Methods36 New zealand rabbits were divided randomly into 3 groups: tongxinluo group(16 rabbits); aspirin group(11 rabbits) and control group(9 rabbits). The rabbits were treated with herb tongxinluo 0.38g·kg-1 · d-1, aspirin 50mg·kg-1 · d -1 and 0.09% natrium chloride 10 ml · d-1 alternatively. The arterial injury model was made 1 week after taking the medicine and the injured segments were taken at 24 hours,1 week or 1 month after the procedure, then the samples were stained by hematoxylin and eosin. The thrombus formation and the neointimal hyperplasia of the injured arteries were observed under microscope. Results The arterial neointimal hyperplasia was seen in both abdominal aorta and iliac artery 24 hours and 7 days after the balloon injury in each group,which led to stenosis in 5%～40% of the arterial lumen, the neointimal hyperplasia was much more significant in 2 rabbits 1 month after the balloon injury. The ratio of the arteries with thrombosis in aspirin group was less than that in the other 2 groups, but the difference was not significant. The ratio of neointimal hyperplasia in tongxinluo group was significantly less than that in aspirin and control groups. Conclusion The balloon injured rabbit abdominal aorta and iliac artery appeare to be an ideal model in researching restenosis after percutaneous transluminar coronary angioplasty(PTCA) . Herbal Tongxinluo significantly inhibit the neointimal hyperplasia of the balloon injured rabbit peripheral arteries, which indicate that herbal Tongxinluo might be a promising medicine in preventing restenosis.

Objective To explore the value of echocardiography in the diagnosis of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) in children.Methods The echocardiographic images of 14 patients with ALCAPA confirmed by operation and 18 patients with endocardial fibroelastosis (EFE) diagnosed by clinical were compared and analyzed.Results Both ALCAPA and EFE exhibited obvious dilated left ventricle,decreased left ventricular systolic function,thick endocardium and mitral regurgitation of different degree.The former additionally showed dilated right coronary artery(RCA) with normal origin,left coronary artery(LCA) emerging from the root or wall of the pulmonary artery(PA),the retrograde flow into PA in LCA and abundant collateral vessels in myocardium.However the later exhibited normal diameter of LCA and RCA and no collateral vessels.Conclusions Color Doppler echocardiography not only demonstrates left ventricular systolic function,endocardium,mitrial regurgitation and collateral vessels in myocardium,but also shows the origination and courses of LCA clearly,which provide exact informations to diagnose ALCAPA.The echocardiography can be used as a powerful tool of ALCAPA diagnosis and preoperative assessment.

Objective To investigate the alteration of phosphorylated GluR1Ser831 and behavioural effects in a rat model of levodopa-induced motor complications after Ca2 +/calmodulin-dependent protein kinase Ⅱ (CaMKⅡ) inhibitor KN-93 treatment. Methods The hemi-parkinsonian rat model was produced by injecting stereotaxically 6-OHDA to right medial forebrain bundle. Then, rats were intraperitoneally treated with levodopa ( 50 mg/kg with benserazide 12.5 mg/kg,twice daily) for 22 days. On day 23 ,rats received KN-93 before levodopa administration. Rotational duration was estimated. After sacrificed, subcellualr distribution of GluR1 and phosphorylated GluR1Ser831 were observed by western blot. Results The study showed that CaMKⅡ inhibitor KN-93 prolonged rotational duration. Moreover, KN-93 could regulate subcellular distribution of GluR1 and reduce hyperphosphorylation of GluR1 Ser831, which was closely associated with levodopa-induced motor complications. The expression of membrane GluR1 and phosphorylated GluR1Ser831 was (83.4 ±4.2)% and (47.2 ±5.2)% ,respectively. Conclusions These results indicated that activation of CaMKⅡ contributed to development of motor complications, through a mechanism that involved an increase in phosphorylated GluR1 Ser831. Pharmaceuticals which act to inhibit CaMKⅡ may be useful in the treatment of the motor complications in parkinsonian patients.
