脑死亡的

The results show that:44 out of 179 cases are of HECHDT,and 37 out of 179 cases are of death; the occurrence rate of digestive tract hemorrhage resulted from the hemorrhage of cerebral basis segment complicated by ventricle hematocele is the highest,and the sequence of the occurrence rates resulted from other position is subarchnoid cavity,brainstem,cerebral lobes,cerebellum,and within cerebral basis segment's hemorrhage; the encephalorrhagia complicated by the hemorrhage of digestive tract is mainly related to the factors of ventricular hematocele,center-line structure shift,hematoma quantity etc,and its case mortality is relatively high.

结果表明：179例中并发消化道出血44例(24.6%)，死亡37例(20.7%)；消化道出血发生率以脑基底节区出血并脑室积血为最高(38.9%)，其次依序为蛛网膜下腔、脑干、脑叶、小脑和局限于脑基底节区出血；并发消化道出血的病死率为50%，无消化道出血的病死率为11.1%。脑出血并发消化道出血主要与出血溢入脑室、中线结构移位、血肿量大等因素有关，且病死率高。

Methods: 10 cases of normal brain specimens with axial and sagitta scans of SE sequences were chosen on MRI. Anatomical features of cerebral sulci were recorded and measured.

取10具非病变死亡的头颅标本，经福尔马林液固定后行MRI扫描及断层切片；测量大脑主要沟回的长度并对邻近脑沟回形成的特殊解剖标志进行了辨识。

The preliminary localization of lethal lesions in in-jured brain-stem indicated that,lesions in the neural structure concerning the respira-tory center and cardiovascular center might be the cause of death,which were prin-cipally on or close to the line linking the posterior angle of fourth ventricle at thedorsal surface and interpeduncular fossa at the ventral side.

脑干损伤致死性病变的初步定位提示，第四脑室下角与脚间窝之间的连线及附近的神经结构受损可能是机体死亡的原因。根据文献，此部位与机体的呼吸中枢和心血管中枢有关。

Craving the calm you get from yoga? Go for an orgasm instead. You feel relaxed after climaxing because you were practically brain-dead while you were doing it. Using scans to measure brain activity, researchers from the Netherlands found that women do not experience emotions such as fear, anxiety and stress during orgasm. When you're in the throes, there's no worrying about the kids' report cards, the weekly grocery l is t or the pile of bills on your desk.

你从瑜伽渴望得到平静，取而代之是一个高潮，高潮后，你感到轻松，而你这样做的时候，因为你几乎脑死亡，利用扫描测量大脑活动，来自荷兰的研究人员发现，女性不会在情绪高潮时，出现这样的恐惧，焦虑和压力，当你在挣扎时，不会担忧没孩子们的成绩单，每周的购物清单或在您的书桌一堆账单。

But in the 18 dead cases, there are 13 whose blood fiow velocity of end systolic stage are lower than those of end diastolic stage. Conclusion The blood flow velocity of patients with subtentorial brain injury or metabolic or diffused brain disease have no obvious change.

结果 浅昏迷患者的TCD表现无特征性改变，当出现中度昏迷或深昏迷时，颅内幕上结构损害患者TCD表现与文献报告相似，颅内幕下结构损害、代谢及弥漫性脑病患者大脑中动脉血流速度改变不明显，但死亡的18例病人中有13例出现了收缩期末血流速低于舒张期末血流速。

In moderate or deep coma patients, who have intracranial supratentorial injury, the TCD manifestations are similar to related documents.
