The long-term opening of mitochondria permeability transition pore results in the release of cytochrome C, apoptosis inducing factors, Ca2+ and other apoptosis factors into cytoplasm, which can destruct the whole cell structure and function by activating the main member of apoptosis protein family——caspase, or destroying the intranuclear chromoplasm independently, or affecting other protein relying on Ca2+, and finally lead to the formation of apoptotic body.

线粒体是真核生物能量和代谢的中心，也是细胞凋亡信号传导途径中起关键作用的细胞器，越来越多的研究表明，在凋亡信号的刺激下，线粒体发生膨胀，其外膜膜电位降低，外膜破裂后释放出膜间隙的诸多凋亡效应因子，在细胞凋亡中起着主开关的作用。

Results (1)The permillage of myocyte apoptosis in infarct area in elder patients with sudden death caused by AMI was significantly higher than that in control group(663.00‰±117.12‰ vs 34.30‰±20.68‰,P＜0 .01).However the permillage of myocyte apoptosis in 1-vessel,2-vessel,and 3 - vessel disease were 514.28±165.12‰,564.38‰±102.33‰ and 668.25‰±127. 19‰,respectiverly,significantly higher as compared to control group(All P＜ 0.01).But no significance was found among the three groups.(2)The size of DNA f ragment about 180～200 bp was found only in those patients with two and three ve ssels involoved.(3)The electron microscope showed the characteristics of myocyte apoptosis episodes,the others showed the characteristics of necrosis.

结果 TUNEL法发现，猝死者梗死区的心肌细胞凋亡千分数老年组(663.00‰±117.12‰)明显高于正常对照(34.30‰±20.68‰)(P＜0.001)；心肌细胞凋亡千分数在冠脉1支病变者(514.28‰±165.12‰)＜2支病变者(564.38‰±102.12‰)＜3支病变者(668.25‰±127.19‰)，虽然均明显高于正常对照(均P＜0.01)，但三组之间比较则无统计学上的差别(均P＞0.05)；冠脉2～3支病变者梗死区的心肌细胞DNA电泳可见相差约180～220 bp的阶梯片段；电镜发现猝死者梗死区内的心肌细胞核膜完整、染色质浓集、电子密度增加的凋亡特征，有的则出现核膜破裂、染色质溶解成碎屑的坏死现象。

Germinal vesicle breakdown and the first polar body (PB1) extrusion were observed in all groups.

观察各组生发卵泡破裂和第一极体(PB1)的形成，出现PB1的卵母细胞视为核成熟。

Some evidence indicates that the combination of extrinsic, intrinsic and genetic factors all play a role to cause the disc degeneration, with a progressive decrease in proteoglycan content leading to dehydration of the nucleus pulposus, and Type Ⅰ collagen begins to appear in the matrix, the ratio between Type Ⅰ and Type Ⅱ increases. All these cause the swelling pressure, disc height and the disc load bearing ability decrease. The disc progressively herniate and cause radiculopathy and myelopathy.

内因、外因及遗传方面的诸多因素导致椎间盘逐步退变后，其实质就是基质中蛋白多糖的减少，含水量降低，Ⅰ型胶原出现在基质中，Ⅰ、Ⅱ型胶原的比例明显上升，髓核呈纤维样改变，导致椎间盘的膨胀压降低，承重能力下降，椎间高度降低，椎间盘承受的重力不能平均地向各方向传递，致使纤维环疲劳、破裂、髓核突出，造成脊髓或马尾神经受压，引起严重后果。

Results Under TEM, the surface and nuclear membrane split, a great number of vacuoles and high electron density particles appeared in the cytoplasm in Pc trophozoites, vacuoles also did in Pc cysts, intracystic bodies became denaturation and necrosis; under SEM, filopodia and microvilli became sparse,short and fell off, a breach appeared in the surface membrane in Pc trophozoites.
