More precious than all worldly riches is Freedom--freedom from the painful constipation and poor narrowness of ecclesiasticism--freedom in manners, habiliments, furniture, from the silliness and tyranny of lacal fashions--entire freedom from party rings and mere conventions in Politics--and better than all, a general freedom of oneself from the tyrannic domination of vices, habits, appetites, under which nearly every man of us (often the greatest brawler for freedom), is enslaved.

比世俗的一切财富更宝贵的是自由，自由是指从教会神学的痛苦闭塞的可悲的狭隘中解脱出来；自由是指在礼仪、服饰、家具上自行其是，从地方史上的愚蠢和束缚中解脱出来；自由是指完完全全从党派的小圈子和政治运作的旧例中解脱出来；最为重要的，自由是指把自我从奴役我们几乎每个人（我们常常大声喧嚷着要自由）的罪恶、恶习、欲望的严酷压榨下完全解脱出来。

Cases had non-isolated splenic vein occlusion, including 6 cases with interruptive thrombosis in PV-SV-SMV junction and 3 cases with stenosis or occlusion near PV trunk and SMV. 30 cases had been combined with twist vein collateral circulation and 6 cases with portal hypertension.

The importance of starlike inner race no-flash die forging process of automobile constant velocity universal joint is introduced.

介绍轿车等速万向节星形套闭塞模锻工艺的必要性，通过数值模拟方法研究该工艺过程，研制出了可生产应用的闭塞模锻液压模架，并进行了工艺试验，研究结果对汽车关键零部件闭塞模锻工艺选择和模具设计提供了技术指导。

Objectives: The most frequent anatomicopathological phenomenon in the early hours of the acute myocardial infarction is the total occlusion of the culprit coronary artery.

目的 急性心肌梗死（ acute myocardial infarction，AMI）早期最显而易见的病理解剖学现象为冠状动脉的完全闭塞，所以，既往人们的研究兴趣以及治疗策略大多集中于心外膜下的闭塞冠脉，并且已有多种成熟应用于临床的闭塞冠脉血运重建措施。

However, grade II CT signs did not always result from type 2 occlusion; 21.1% of patients with grade II CT signs had type 4 occlusion. When the MCA trunk is short, the lateral group of the lenticulostriate arteries may arise from the M2 segment[2, 12]. In such cases, type 4 occlusion may also involve the lateral or posterior part of the putamen.

但是，II级早期CT征象（部分壳核后外侧区出现低密度）并非仅仅由2型大脑中动脉闭塞（包括部分豆纹动脉在内的大脑中动脉主干闭塞，豆纹动脉部分受累）引起；本研究中，21.1%深部大脑中动脉分布区出现II级早期CT征象（部分壳核后外侧区出现低密度）的患者，是因4型大脑中动脉闭塞（大脑中动脉M2段闭塞）引起的；这些患者的大脑中动脉主干均很短，因此外侧豆纹动脉群（lateral lenticulostriate arteries）是由大脑中动脉M2段发出的；此时，4型大脑中动脉闭塞（大脑中动脉M2段闭塞）也可以导致壳核后部或外侧部出现低密度（深部大脑中动脉分布区II级早期CT征象）。

On the part of the selfish, the prejudices, shadows of costly education, appetite increasing through intoxication, a giddiness of prosperity which dulls, a fear of suffering which, in some, goes as far as an aversion for the suffering, an implacable satisfaction, the I so swollen that it bars the soul; on the side of the wretched covetousness, envy, hatred of seeing others enjoy, the profound impulses of the human beast towards assuaging its desires, hearts full of mist, sadness, need, fatality, impure and simple ignorance.

在自私的人方面，有种种成见，那种发家致富教育的毒害，越吃越馋的胃口，财迷心窍的丧心病狂，对受苦的惧怕，有些竟恶化到了对受苦人的厌恶，毫不容情地要满足自己的欲念，自负到了精神闭塞的状态；在贫苦的人方面，有羡慕心、嫉妒心、见别人快乐而起的愤恨、因追求满足而发自内心深处的兽性冲动、充满了迷雾的心、忧愁、希求、怨命、不洁而又单纯的无知。

It is urgent to solve how to produce it efficiently and economically.In this paper, with the guidance of precision forming complex components, basing on the forming theory of obturated-extrusion, combining the technique of hot extrusion, considering the characteristics of steering knuckle, so the one-step precision obturated lateral-bend extrusion forming method and the two-step forming method are presented.

本文以复杂零件的精密成形为指导思想，根据闭塞挤压成形理论，结合热挤压技术，针对轿车转向节零件的自身特点，提出轿车转向节零件的闭塞侧弯挤压精密一步成形法和闭塞侧弯挤压精密预制坯与开式终锻相结合的两步成形法两种工艺。

PART 1 EXPRESSION OF MMP/TIMP IN SKELETAL MUSCLE OF ARTERIAL OCCLUSION DISEASE MODELS OF DOG'S HIND LIMB Objective To study the distribution changes of typeⅠand typeⅢcollagen in skeletal muscle of arterial occlusion disease models of dog's hind limb and the expression of MMP-2/TIMP-2 in skeletal muscle of arterial occlusion disease models of dog's hind limb.
