结果脑梗死患者大部分存在颈动脉斑块及不同程度颈动脉狭窄。170例检出颈动脉斑块的患者中，以不规则、不均质性回声斑块多见(P.001)。

The concentrations of TNF-αand IL-10 in peripheral blood increased significantly after CVVH.The concentration of NO decreased significantly after CVVH.There was no TNF-αin ultrafiltrate;IL-10 was detected little and NO was detected much in ultrafiltate.Compared with prefilter,the concentration of TNF-αin postfilter blood decreased significantly at 1h of CVVH and increased at the end of CVVH. Compared with prefilter,the concentration of NO in postfilter blood decreased significantly at 1h ,12h and the end of CVVH.

CVVH治疗后患者血清TNF-α、IL-10浓度与治疗前相比明显升高，而NO浓度与治疗前相比显著下降，超滤液中未能检测出TNF-α，仅检测到少量IL-10，但NO在超滤液中浓度较高；CVVH治疗1h时，静脉端血清TNF-α浓度明显低于动脉端，CVVH治疗结束时，静脉端血清TNF-α浓度明显高于动脉端；CVVH治疗1h，12h和结束时，静脉端血清NO浓度均明显低于动脉端。

Bladder artery comes from umbilical artery and along the bladder border to the bladder top and branchestoward bladder ventrally or dosally wall.

膀胱动脉主要起自脐动脉，沿膀胱侧缘行向膀胱顶，沿途发出1～4支基本对称的分支分布于膀胱前面，两侧膀胱动脉的分支在其表面有吻合现象。

Results: Lateral extradural approach could be used to expose the second and third branches of trigeminal nerve,trigeminal ganglion,posterior vertical segment of the intrapetrosal ICA,abducent nerve and horizontal segment of the intrapetrosal ICA;lateral intradural approach could be used to expose the lateral,anteroinferior and posterosuperior venous spaces,almost all the cranial nerves within the cavernous sinus and horizontal segments of the intracavernous ICA;superior approach could be used to expose the medial,lateral and posterosuperior venous spaces,medial side of the anterior genu,anterior vertical and clinoidal segments of the intracavernous ICA and the lateral side of the hypophysis.

结果：外侧硬膜外入路可用于显露三叉神经第2、3支，三叉神经节，海绵窦内颈内动脉后垂直段，外展神经及岩骨颈内动脉水平段；侧方硬膜下入路可用于显露海绵窦外侧及前下，后上静脉间隙，以及所有走行在海绵窦内的颅神经和海绵窦内颈内动脉水平段；上方入路可用于显露海绵窦内侧、外侧及后上间隙，海绵窦内ICA水平段、前膝、前垂直段及床突段的内侧面，以及垂体的外侧面。

Because the renin-angiotensin system participate in not only humoral regulation of body fluid and systemic blood pressure but also structural and functional autoregulations in many tissues, we speculated that it may play a pivotal role in arterial structural and functional autoregulations, myocardial and renal adaptational changes due to simulated weightlessness.

我们推想局部肾素-血管紧张素系统(local renin-angiotensinsystem，L-RAS)在模拟失重引起的动脉、心肌和肾功能等的适应性变化中可能发挥关键性调节作用；且本室前一工作已发现4-wk模拟失重大鼠基底动脉与股动脉血管组织血管紧张素原(angiotensinogen，AGT)的基因表达分别呈增高与降低变化。

Objective To research the angiographic embolism end-point for uterine artery embolisation to treat uterine fibroids or adenomyoma when there were type Razavi-Ⅰ uterus artery and ovary artery anastomosis.

目的 探讨子宫动脉栓塞治疗子宫肌瘤或腺肌瘤在有Razavi-Ⅰ型子宫动脉-卵巢动脉吻合时的栓塞终点。

ABI between normal retinal artery group and anormal retinal artery group had statistically significant difference (P.001), the more severity of retinal artery the lower ABI.

眼底动脉正常组与眼底动脉病变组踝臂指数差异显著(P.001)，眼底动脉病变越严重踝臂指数越小。

The results obtained are as follows:(1) injection of 50, 100, and 200 nmol/kg adenosine into the renal artery increased the renal afferent nerve activity in a dose-dependent manner with unchanged arterial pressure;(2) pretreatment with 8-cyclopenthl -1,3-dipropylxanthine (DPCPX, 160 nmol/kg), an adenosine A1 receptor antagonist, partly abolished the effect of adenosine; and (3) pretreatment with a nitric oxide synthase inhibitor N w-nitro- L -arginine methylester (L -NAME, 0.1 mmol/kg) significantly enhanced the ARNA response to adenosine.

结果表明：(1)肾动脉内注射50， 100和200 nmol/kg腺苷可呈剂量依赖性地兴奋肾神经传入纤维的活动，而动脉血压不变。(2)肾动脉内预先应用选择性腺苷A1受体阻断剂DPCPX (160 nmol/kg)，可部分阻断腺苷对肾神经传入纤维的兴奋作用。(3)静脉应用一氧化氮合酶抑制剂 L -NAME(0.1 mmol/kg)预处理，延长并增强了肾神经传入纤维对腺苷的反应。

结果表明：(1)肾动脉内注射50，100和200nmol/kg腺苷可呈剂量依赖性地兴奋肾神经传入纤维的活动，而动脉血压不变。(2)肾动脉内预先应用选择性腺苷A1受体阻断剂DPCPX(160nmol/kg)，可部分阻断腺苷对肾神经传入纤维的兴奋作用。(3)静脉应用一氧化氮合酶抑制剂L-NAME(0.1mmol/kg)预处理，延长并增强了肾神经传入纤维对腺苷的反应。

The proliferation of medial smooth muscle cells and collagenous fibers of pulmonary arteriole in patients with PH were observed by electron microscopy.

电镜下，中重度PH组肺细小动脉中膜平滑肌增生，外膜胶原纤维密集；轻度PH组肺细小动脉中膜平滑肌细胞和外膜胶原纤维增生轻于中重度PH组；无PH组肺细小动脉结构改变不明显。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
