阻断

AIM: To observe the effect of endothelin receptor antagonist (BQ123) on calcification in rat vascular smooth muscle cells in vitro. METHODS: Calcification of cultured rat VSMCs was produced by incubation with β-glycerophosphate.

目的：在离体钙化的血管平滑肌细胞上，观察内皮素受体阻断剂对血管平滑肌细胞钙化的影响，探讨内皮素促进细胞钙化的信号转导和分子机制。

METHODS:Calcification of cultured rat VSMCs was produced by incubation with β-glycerophosphate. Calcium content, Ca2+ deposition and alkaline phosphatase activity were analyzed to estimate the extent of calcification.

The analgesic effect elicited by morphine injected into amygdala was in turn blocked by naloxone administered to habenula.

杏仁核内注射吗啡产生的镇痛作用可被缰核内注射NX所阻断。

Thus, the analgesic effect of morphine injected into PAG was significantly attenuated by β-EP AS injected into the nucleus accumbens, and vice versa. This antagonistic effect was totally abolished by lesioning of the ARH. Moreover the analgesic effect of morphine injected into nucleus accumbens could be blocked byβ-EP AS administered te amygdala or habenula.

在PAG内注射吗啡产生的镇痛作用可被伏核内注射β-EP抗体所削弱，损毁家兔的ARH后这一对抗效应基本消失；在伏核内注射吗啡产生的镇痛作用可被PAG内注射β-EP抗体所对抗，损毁ARH后上述对抗效应基本消失；伏核内注射吗啡产生的镇痛作用亦可被杏仁核内或缰核内注射β-EP抗体所阻断。

Methods Under aseptic condition, mechanically blocking of the hepatoduodenal ligement was adopted in rabbit model, both endotoxin level of the portal blood and positive bacterial cultures in the mensenteric lymph nodes were observed at 15, 20, 30 and 60 min respectively after the blocking.

采用兔动物模型，在无菌条件下机械性阻断肝十二指肠韧带，观察阻断后15，20，30min和60min时门静脉血中内毒素值和肠系膜淋巴结细菌培养阳性数。

Methods Hepatoduodenal ligament was blocked under normal temperature and aseptic condition in rabbits model to lead to an intestinal anoxia and damage of intestinal mucosa barrier, and then a great quantity of endotoxin would enter portal vein through intestinal wall resulting in endotoxinemia.

采用兔做动物模型，在常温无菌条件下机械性阻断肝十二指肠韧带造成肠道缺血、缺氧、肠黏膜屏障损害，肠道内大量内毒素穿过肠壁进入门静脉，造成内毒素血症。

Methods: Sixty-three cases of left hepatolith underwent operations of left-half hepatectomy, Roux-en-Y cholangio-jejunostomy and removal of stones by cholangiotomy under the condition of hemihepatic blood flow occlusion at normal atmospheric temperature.

回顾性总结63例左肝内胆管结石患者在常温下阻断左半肝血流，行左肝叶切除、肝内含石胆管直视下切开取石和肝胆管Roux-en-Y胆肠吻合等手术后，患者术后并发症、肝内胆管结石的复发率、再手术率以及术后患者的肝功能恢复情况等。

Methods: Sixtythree cases of left hepatolith underwent operations of lefthalf hepatectomy, RouxenY cholangiojejunostomy and removal of stones by cholangiotomy under the condition of hemihepatic blood flow occlusion at normal atmospheric temperature.

回顾性总结63例左肝内胆管结石患者在常温下阻断左半肝血流，行左肝叶切除、肝内含石胆管直视下切开取石和肝胆管Roux-en-Y胆肠吻合等手术后，患者术后并发症、肝内胆管结石的复发率、再手术率以及术后患者的肝功能恢复情况等。

This has led to the deelopment of a new drug, HXR9 that blocks the actiity of a group of genes known as the HOX family.

他们开发出了新的药物HXR9，其可阻断已知HOX家族的一组基因的活性。

The anesthetic mixture consisted of 10ml of ropivacaine 1% and lidocaine hydrocarbonate 2% with epinephrine 1:200,000. The spread of the solution around the subclavian artery could be visualized using our imaging probe.

所有的神经阻断均在超音波探头的影像下操作，使用的局部麻醉剂为10ml之1% ropivacaine与2% lidocaine混合溶液；在超音波的影像下可观察到溶液分布於锁骨下动脉周围。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
