闭塞

It shows that Chp has relation to the extent of ASO. The expression of Chp DNA depends on the lesion of artery, the distal artery of obliteration and the extent of lesion in laterad artery.3. The clinical significance of the Chp detectionThe macrolide antibiotic is a kind of drug that is used to treat Chp infection.

2· 二人hp与ASO严重程度的关系本研究表明，ChPDNA的阳性表达率随ASO的严重程度而升高，说明ChP与ASO病变程度相关，即ChpDNA表达的变化取决于动脉本身病变、闭塞远端血管及侧枝血管内皮细胞的损伤程度。

Site of occlusion and involvement of the lenticulostriate arteries were confirmed by angiography.

动脉闭塞的位置及豆纹动脉究竟是否受累，则通过行脑血管造影来进一步明确。

The presence of ALN in 16% of patients with branch occlusions appeared to result from variation in the lenticulostriate arteries, which arise from the middle cerebral artery branch in around 20% of cases.

本研究中，有16%的大脑中动脉分支闭塞的患者也出现了豆状核低信号征；我们认为，这可能与豆纹动脉的解剖变异有关，因为有20%的人群地豆纹动脉并非由大脑中动脉M1段发出，而是由大脑中动脉分支所发出的。

Therefore, site of arterial occlusion and involvement of the lenticulostriate arteries may be presumed, to some extent, by precise evaluation of early CT signs in the deep MCA territories.

因此，从某种程度上说，通过对深部大脑中动脉分布区出现的早期CT征象进行精确的评估，可以推测出动脉闭塞的位置及豆纹动脉是否受累。

On the other hand, sensitivity and specificity of grade II and grade III CT signs for presence of lenticulostriate artery involvement in ischemia were 77% and 100%, respectively.

II级CT征象和III级CT征象提示豆纹动脉受累的敏感性及特异性分别为77%及100%。不同的动脉闭塞位置均可导致出现II级CT征象

Grade II CT signs resulted from various sites of occlusion, whereas grade III was unequivocally predictive of proximal occlusion to all of the lenticulostriate arteries.

而III级CT征象则均明确地提示：大脑中动脉主干的起始段发生了闭塞、所有豆纹动脉均受累缺血。

Although a grade II CT sign resulted from various types of MCA occlusion, it was reliably predictive for the presence of partial, or sometimes total, involvement of the lenticulostriate arteries in ischemia.

尽管深部大脑中动脉分布区II级早期CT征象（部分壳核后外侧区出现低密度）可因各种类型的动脉闭塞位置所引起；但通常提示部分或所有豆纹动脉受累发生缺血。

MSCTA showed stenosis and obstruction of internal carotid artery, anterior cerebral artery and middle cerebral artery, including thirteen cases with bilateral and 6 cases with single lateral. There appeared abnormal vessels looked like smog on cerebral bottom. More than one branches of collateral artery could be seen in most of them. Sacculated aneurysm of lenticulostriate artery was shown in one patient. Five patients who were performed both MSCTA and DSA displayed similar above-mentioned vascular lesions.

MSCTA均清晰显示不同程度颈内动脉虹吸段、大脑前动脉及大脑中动脉起始段狭窄、闭塞，双侧病变者13例（68.4%），单侧病变者6例（31.6%）；脑底部见纤细迂曲的&烟雾&状异常血管网；大多可显示1支以上侧支动脉；1例显示右侧豆纹动脉囊状动脉瘤。5例同时行MSCTA与DSA者，均很好显示了上述血管病变。

In addition, the loss of the gray-white differentiation in the cortical ribbon (particularly at the lateral margins of the insula) or the lentiform nucleus and sulcal effacement can often be detected within 6 hours in up to 82% of patients with large-vessel anterior circulation occlusions.

另外，82％的前循环大动脉闭塞的患者，于发病6小时内，CT即可发现岛带征（岛叶外侧缘皮层灰白质分界消失）、豆状核低信号征、半球脑沟消失征；这些早期CT征象的出现往往提示预后不良。

I attempe to talk about 4 teenagers'rebellion and disturbance in their puberty under the conditions and disturbance in their puberty under the conditions of out-of-date and backward,using a film in a prose style,in which I employ a structure like stringing pearls,try a kind of psychological emotion as its main content and use repeated behaviours and limbed movements as its form of _expression_r

我采用串珠式的结构方式力求形成一种以心理情绪为内容主体。以反复行为方式和肢体动作为表现形式的散文体影片。来讲述闭塞。落后环境下。四个少年青春期的叛逆和骚动。

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。
