Objective: To observe thrombin activity in a rat model of aortic endothelial denudation.

目的：观察大鼠主动脉拉伤模型血管壁凝血酶活性的变化。

METHODS We used a dermatome to obtain thin endocardium, midcardium and epicardium transmural strips from left ventricular free wall of canine (weight 15-18 kg) and standard microelectrode techniques to record and measure the transmembrane action potential duration.

应用标准玻璃微电极技术，在不同频率刺激下，记录应用胺碘酮前后犬左室游离壁内、外膜及中层心肌细胞跨膜动作电位各种参数的变化。

Following 72 h co-culture, desquamate, sporozoites, trophozoites, meronts, microgametocytes, macrogametocytes, zygote, thin-wall oocyst, and thick-wall oocyst appeared orderly. Between the 60th and 72th hour, many oocysts emerged. Inoculated by the C. parvum -infected cell culture supernatant at the 48th hour, the immunosuppressed mice became infected.

在感染后72 h内，隐孢子虫出现连续发育阶段，包括脱囊、子孢子、裂殖子、裂殖体、滋养体、配子体、合子、薄壁卵囊和厚壁卵囊，在60～72 h内形成卵囊；用感染48 h的细胞培养上清接种于免疫抑制小鼠， 10 d后有隐孢子虫卵囊排出。

Results:①No differences were observed between two groups on the distribution of coronary vessel diseased (narrowing≥50.0% of diametre)(p＞0.05).Left ventriculography did not show that inferior wall motion were strikingly diminished in the both Group A and Group B.

结果：①选择性冠状动脉造影显示冠状动脉病变(狭窄≥50.00%)支数在两组间的分布无显著差异(P＞0.05)；左心室造影两组均未见下壁运动明显减弱。

Palladium nanoparticles were crystallized on 4-aminobenzoic acid monolayer-grafted multi-walled carbon nanotubes by diazotization.

本工作中在水溶液体系中以芳烃重氮盐修饰的多壁碳纳米管为载体构筑了钯纳米粒子碳纳米管复合结构。

However, most of the diehard climbers agree that there's nothing like natural rock.

然而，多数铁杆的攀岩者都认为没有什么可以和自然岩壁相提并论了。

Results:1、Three distinct bladder mucosa patterns were seen:normal mucosa and wall,but the urine was light-echogenic;the mucosa and wall thickened with enhanced echoes and irregular mucosa;local mucosa thickened in rhomb or flat figure.2、The bladder wall diffusively thickened or somewhere,three layers of the wall clear or obscure.3、Some echoes spots floating in the urine.

结果：1、膀胱粘膜图像可分为三类：A、粘膜未见确切异常回声，但尿液有漂移光点；B、粘膜弥漫性增厚，回声增强，粗糙不光滑呈细颗粒状、断续状表现；C、粘膜局灶性增厚呈棱形或扁平状；2、膀胱壁回声可正常，弥漫性增厚或局灶性增厚，三层结构可辨，基本可辨或分辨较差；3、尿液内出现不同程度的光点透声。

Objective To study the efficacy of therapy for diplopia caused by orbit blowout fracture with the method of early passive pull.

目的 探讨早期被动牵拉手法在爆裂性眶壁骨折所致复视治疗中的作用。

The therapy are effective for diplopia caused by orbi...

对爆裂性眶壁骨折所致复视病人有选择地进行眼球早期被动牵拉治疗，是一种积极且有效的方法。

In lens-induced experimental myopias of guinea pigs, increasing of MMP-2 and decreasing of TIMP-2 occur in posterior scleral matrix. This pair of disbalance of MMP-2 and TIMP-2 can cause abnormal growth of guinea pig's eyeball.

透镜诱导豚鼠实验性近视眼巩膜基质中MMP-2活性增强，TIMP-2活性降低，二者平衡失调可导致巩膜胶原的降解，巩膜壁变薄，引起眼球扩张，眼轴延长。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
