治疗以清宫术为主，对急性大出血者可行髂内动脉结扎或子宫切除术。同济医院目前应用的经皮髂内动脉造影栓塞治疗为一安全可靠的方法，值得推广。

Since 1962, when Gross and Lapiere discovered the first MMPs-collagenase, man had discovered various of MMPs in succession, where MMP-2 has a strong degradational effect on extracellular matrix, it is secreted bymacrophage, smooth muscle cells and endothelial cells and so on.

自从 1962年 Gross和 Lapiere发现第一种基质金属蛋白酶一胶原酶以来，人类陆续发现了很多种基质金属蛋白酶，其中的MMP—2对细胞外基质具有极强的降解作用，它由巨噬细胞、平滑肌细胞以及内皮细胞等分泌，在动脉粥样硬化斑块中憎多时降解纤维帽及基底膜的胶原等基质成分，是使纤维帽变薄及加速动脉粥样硬化的重要因素之一。

METHODS: Newborn rats in the model and laser treatment groups were treated with low-concentration oxygen (containing 8% O2 and 92% N2) following deligation of the left common carotid artery to establish models of ischemia-hypoxia brain damage. Rats in the sham operation group did not receive deligation of the left common carotid artery, but exposed to the air.

模型组、激光治疗组新生大鼠通过结扎左颈总动脉后，再吸入低浓度氧(含体积分数为8%的O2、体积分数为92%的N2)建立缺血缺氧性脑损伤模型；假手术组不结扎左颈总动脉，置于正常空气中。

In this study, a model of atherosclerosis was developed by a high-cholesterol diet, vitamin D〓 and endothelium denudate.

本实验采用高脂饲料加维生素D结合机械性损伤内皮来建立大鼠动脉粥样硬化模型，来研究发展到动脉粥样硬化时的特点并与单纯高脂血症时做比较。

The signal will not dephase, so arteries will be bright on diastolic scans.

在舒张期时，动脉内的血流因为流速相对缓慢而不会产生失相位，动脉呈高信号。

Especially the formation of reversal gradient of blood pressure before the dicrotic notch.

特别是逆向血压梯度的形成，认为动脉血流的惯性及左心室的舒张是重搏波切迹前短时期内近心端血压低于远心端血压的主要原因，在动脉中存在着惯性动能与压力势能之间的相互转化。

The stenotic degree of cerebral arteries on MR angiogram was correlated to the severity of MRI manifestations positively, but very dispersively. The overestimation to artery stonesis is still in existence.

MRA显示动脉的狭窄程度与MRI改变程度呈正相关趋势，但分布分散，对动脉狭窄仍存在过度评价。

The pressor effect of adenosine was due to carotid body cheoreceptor activation. However, a slight increase of ABP induced by intracarotid bolus injection of adenosine following the section of carotid sinus nerves was observed in a few rats, which implied that the central effect might be involved in the pressor effect of adenosine. The delayed effect of adenosine may be attributed to the direct actions (including the negative chronotropic action, thenegative dromotropic action, the negative inotropic action and the vasodilator effect) of adenosine on the heart and blood vessels.

前一效应主要与颈动脉体化学感受器的激活有关，但在少数动物，颈动脉内注射腺苷的升压效应在切除窦神经后并未完全消除，表明腺苷有可能进入神经中枢而发挥作用；后一效应可能由腺苷直接作用于心脏和血管，通过其负性变力、变时、变传导和血管扩张等作用，导致心脏自律性降低，输出量减少和外周阻力下降。

Results The negative correlations were found on the Glasgow Outcome Scoreto the items such as conscious state at admission,Glasgow Coma Score,psychiatric symptoms,hemiplegia,Babinski sign,abnomal degree of Electroencephalogram,focal lesions found by neuro-image investigation and mean peak flow velocityand pulsatility indexof basilar artery and vertebral arteries by transcranial Doppler ultrasonography investigation;The non-correlation was found on the Glasgow Outcome Score to theitems such as headache,febrile,epilepˉsia style,the involvement of cranial nerve,dystaxia,neck stiffness,Cerebrospinal fluid investigation and blood serum enzymology.

结果 入院时的意识状态、GCS、精神症状、偏瘫和/或偏身感觉障碍、巴彬斯基征以及脑电图异常程度、影像学所见的病灶范围、基底动脉和椎动脉的平均峰流速、脉动指数和Glasgow预后评分呈负相关；头痛、发热、癫痫类型、颅神经受累情况、共济运动、脑膜刺激征、脑脊液检查（含压力、蛋白定量、细胞数、HSV-PCR）以及血清酶学的变化和Glasgow预后评分之间无相关性。结论入院时的意识状态、GCS、精神症状、局灶性神经系统体征以及脑电图异常程度、影像学所见的病灶范围、后循环的血管痉挛程度和血流阻力等是影响病脑预后的主要因素。

And discuss some key point of integrated management system design, include hazard identification and risk assessment and risk control in the occupational health and safety management, the measure of satisfaction target of customer, the flawlessness of law system, the integration of the integrated management system and enterprise standardization system, unify lead institution and work orgnization, integreted internal audit and integrated management review.

同时，论述了一体化管理体系构建中的几个主要问题，包括职业健康安全管理中的危险源辨识、风险评价和风险控制、顾客满意度的科学监测、法律、法规体系的完善、一体化管理体系与企业标准化体系的有机结合、统一的领导机构和工作机构、一体化的内部审核和管理评审。
