The effective stimulating sites were indentified by defensive cardiovascular response and other components of defence reaction evoked by 3 s trains of rectangular cathodal pulses (100Hz, 0.5ms pulse duration, 70 -150μA intensity for dPAG and 150-250μA for PF) delivered from a programmed multichannel constant current stimulator. The responses included an increase in blood pressure and heart rate, pupillodilation and an increase in the rate and depth of respiration. Currents of 1Hz, intensity of 100- 150μA for dPAG and 200-250μA for PF were used to observe the effect of the stimulation of them on RVLM neurones. The deep peroneal nerve and superfacial deep peroneal nerve were carefully separated, and put on a pair of stimulating electrode respectively, Both nerves were stimulated with constant rectangular pulses of 1Hz, 0.5ms duration and 300μA current intensity to see their effects on RVLM neurones. The baro-and chemo-receptors were activated by the intravenous injection of phenylephrine or 0.208 M NaH2PO4. The degree of convergent inputs to individual RVLM neurone was studied by the stimulation of the sites mentioned above. It was found that neurones about 61.4%(27/44) and 35.3%(6/17) received convergent inputs from three and four places respectively.

过去的研究主要集中于整体水平，利用电刺激或化学刺激RVLM神经元，观察对血压、心率及交感活动的影响，并对影响心血管交感活动的神经递质进行了广泛探讨，积累了大量资料；在神经元水平，主要研究刺激脑内核团、外周神经、化学感受器及压力感受器等对RVLM神经元放电的影响和某些神经递质影响神经元活动的机制、然而，对RVLM神经元如何整合不同信息、其可能突触机制等研究得较少，本互作拟采用在体细胞内、细胞外记录电活动与微电泳，结合中枢核团及外周神经电刺激等方法，对RVLM神经元在不同状态下的整合作用规律与可能机制进行初步探讨，为进一步了解这一复杂的整合过程提供新的理论依据。

The purpose of this study was to investigate the extracranial carotid stenosis in Chinese patients with ischemic stroke by means of computerized tomographic angiography and ultrasonography .

From the brain stem at the lateral end of ponto medullary sulcas, the distance between the facial nerve, the vestibulocochlear nerve, the abducenst nerves, and the trigeminal nerve were 2.38±0.65mm, 6.62±0.41mm, 7.59±1.08mm.

面神经在桥延沟的外端起自脑干，与其外侧的前庭蜗神经进入脑干处相距2.38+0.65mm，距外侧展神经6.62±0.41mm，距三叉神经7.59±1.08mm。

Compared with flunarizine and nimodipine, in addition the Chinese herb tetramethylpyrazine has the beneficial effects on the antagonism of brain Post-ischemic hypertension or increase of PAP and PCWP, while tetrand- rine showed weak amelioration effects on brain resusci- tation, which may be due to its no selectivity on brain or brain vesseles.

与氟苯桂嗪和尼莫地平相比，中药川芎嗪还具有对抗脑缺血后继发性外周血压和肺血管压升高的独特效应。而汉防己甲素的抗脑缺血损害效应微弱，可能与此药对脑血管、脑细胞选择性作用较低有关。

The coping styles which the stroke patients usually adopted is always unmature. The patients are short of social support.

脑卒中患者的人格具有外倾性和不稳定性；多采用不成熟的应付方式；脑卒中患者缺乏社会支持。

METHODS: Six patients with urinemia underwent renal transplantation with donor kidney of brain death patients from May 2006 to November 2008 at the Organ Transplantation Center, 309th Hospital of Chinese PLA, were selected, including 2 patients receiving kidneys from a brain death patient, 4 patients receiving kidneys from 3 brain death patients.

Fifiteen experiment animals were divided randomly into normal control group, 12h-post-trauma group and 36h-post-trauma group (5 each). Immunohistochemistry and image analysis techniques were used to measure the area, optic density value and integrated optic density value and integrated optic density value of Ngb immunoreactive products in primary somatosensory cortex (S1) and retrosplenial granular b cortex, which was located in the inner side and out side of traumatic brain injury cavity in coronal section of rat brain respectively.
