脑损伤

Empirical study confirm that the effect of acupuncture is versatility and multipath .it could improve the defect of animal neurosis caused by cerebral ischemia damage, could lower the degree of ischemia and anoxemia injury, could promote the injured region's recovery and functional restoration and so on.

实验研究证实，针刺能改善实验性脑缺血损伤动物神经症状的缺损、降低缺血缺氧对组织的损伤程度、促进损伤区的修复和功能重建等。

The brain capillary and star glue quality cell which enwrap around it under thenormal condition form the permeation extremely low blood-brain barrier, onlypermit some little molecule to pass; When cerebral isc.

正常状态下的脑毛细血管及包裹在其周围的星形胶质细胞构成了通透性极低的血脑屏障，只允许一些小分子物质通过；当缺血性中风发生时，微血管通透性发生显著改变，这种病理变化与脑内皮细胞损伤导致的功能变化有直接的关联。

Resluts:It has a infection of delayed intracranical heamatoma such as contusion and laceration of brain or contusion and laceration of brain is on the offside of haematoma;a great deal of haematoma in the brain;fracture of skull,especially the fracture of sinus or medium artery of span meningeal,it is the high risk factors of DTIH,and it get high risk of delayde intracranical hematoma;abnormity of clotting time;falling sickness;a grave scalp injury etc.

结果：脑挫裂伤或血肿对侧有脑挫裂伤；脑内血肿量大；颅骨骨折，尤其是跨脑膜中动脉或静脉窦的颅骨骨折是导致外伤性迟发性颅内血肿的高危因素，发生迟发性颅内血肿的危险性大。出凝血时间异常、癫痫发作、重症头皮损伤等对迟发性血肿的发生也起着一定的影响。

One of main manifestations of SBI is cerebral edema which is one of the most serious complications after head injury, cerebral edema can promote intracranial pressure and lead to malposition of brain tissue, even endanger life because of brain hernia.

SBI主要表现之一为脑水肿，脑水肿是颅脑损伤后最严重的并发症之一，它使颅内压增高和加重，引起脑组织移位甚至脑疝而危及生命。

The p38MAPK activity in the rats brain after ICH is significantly increased, NYA can inhibit the p38 signaling transduction pathway.

脑出血大鼠脑内p38MAPK活性增强，脑溢安能抑制脑出血损伤激活的p38MAPK信号转导通路。

From the resnlts above, NYA can promote the nerve function resumed and mend the hematoma absorbed which has further prored its clinical curative effects that NYA can regulate plasma ET and NO levels, and improve the cerebrovascular function, which may be one of the protective mechanisms of NYA from ischemic injury after ICH.

综合以上结果，脑溢安不仅能促进神经功能恢复，加快血肿吸收，其临床疗效得到进一步证实，而且能有效调节ET和NO水平，改善脑血管内皮细胞舒缩因子的释放，可能是治疗急性脑出血，保护脑出血后缺血性损伤的机制之一。

Following brain stem injury,the number of GFAP-positive astrocytes in cerebral cortex and pervent-ricular area,dorsomedial and ventro-medial pafts of midbrain at 30 min antemortem,and in periventricular area,dorsomedial part of pens,dorso-medial and ventro-medial part of medulla oblongata at 60 min antemortem.

采取针刺法造成实验大白鼠脑干损伤，用免疫组织化学LSAB法检测大脑、中脑、桥脑及延髓等不同部位脑组织中胶质原纤维酸性蛋白的改变。结果发现，生前损伤30min，大脑顶部灰质及中脑腹例中央部的GFAP阳性星形胶质细胞数目增多；生前损伤60min，除大脑顶部灰质及中脑腹侧中央部外。

Methods :25 cases of traumatic hydrocephalus were analysed retrospectively.Among them,3 cases showed brain contusion,4 with subrarchnoid hemorrhage,5 with subdural effusion,2 with epidural hematoma,1 with subdural hematoma,1 with fracture of skull,3 with malacia lesions,3 with cerebral infarction,and 2 with cerebral hernia.The other 3 cases were not associated,with intracranial traumatic anomaly.

回顾分析25例外伤性脑积水，其中分别伴颅脑损伤有3例脑挫伤、4例蛛网膜下腔出血、5例硬膜下积液、1例颅骨骨折、3例脑内软化灶、3例脑梗塞、2例硬膜外血肿、1例硬膜下血肿、2例脑疝(大脑镰下疝及钩回疝各1例)，另3例颅内未见外伤性异常改变与其并存。

Results and Conclusions （1）MRI is better than CT to show the lesion of cerebellar fossa and brain stem.（2）Late radiation encephalopathy may be the result of immunal response to the damage of brain tissue and blood vessel after radiotherapy（3） 18 F-FDG-PET is a effective screenage examimation to diagnosis late radiation encephalopathy.（4）To some degree,the symptoms of the patients were alleviated after therapy with dexamethasome,mannital and vitamine B,etc.Late radiation encephalopathy ought to be given priority to prevention and treated vigorously as soon as possible.

结果和结论（1）CT对鼻咽癌迟发性放射性脑病的诊断有一定价值，但MRI对后颅窝和脑干病变的显示优于CT；（2）迟发性放射性脑病可能是放疗致脑组织血管损伤后引起免疫改变的结果；（3）18-氟代脱氧葡萄糖（ 18F-FDG）-PET是诊断迟发性放射性脑病的有效的影像学检查方法；（4）本组患者经应用激素、甘露醇、多种维生素等治疗，均取得不同程度的改善。

The path-physiological mechanism of ICH is complicated, which includes the high intracranial pressure caused by hematom mechanical pressure, the lesion by the decrease of regional cerebral blood flow surrouding the hematom, even regions adjacent to the hematom, Meanwhile, the materials released from hematom including ferrohemoglobin, thrombase, plasma protein and platelet, leucocyte, glusate not only directly injury neurons but also blood brain barrier.

脑出血的病理生理学机制复杂，其中包括血肿的机械压迫所造成的持续的脑缺血性损害；血肿分解后产生的血红蛋白、凝血酶、血浆蛋白、血小板和白细胞、谷氨酸、自由基等毒性物质不仅可直接损伤神经元，而且可损害血脑屏障加重脑水肿。

The X-ray diffract was used to analyze the crystal structure of the composite. Results show that after the talc was treated with blend coupling agent, the crystal structure of talc changed, and effect Intercalation phenomenon.

通过X射线衍射分析可知，用混合偶联剂对滑石粉进行预处理后，滑石粉晶体结构发生改变，产生了插层现象，使PP／滑石粉复合材料为纳米复合材料。

An authentic Maui wedding might require the services of a 'kahu', which is a Hawaiian minister.
