摘 要:BACKGROUND : Basic fibroblast growth factor (bFGF) can cause proliferation and differentiation of plentiful cells which are derived from mesoblast and neural ectoblast. Previous researches suggested that Tongxinluo could promote differentiation from neural stem cells (NSCs) to neurons and astrocytes after cerebral ischemia/reperfusion injury. OBJECTIVE: To observe the effect of Tongxinluo on bFGF mRNA of rats after cerebral ischemia/reperfusion injury and analyze its dosage-dependence. DESIGN : Randomized controlled study SETTING : Department of Neurology, Nanfang Hospital of Southem Medical University MATERIALS: The experiment was carried out in Neurological Department of Nanfang Hospital affiliated to Southern Medical University from May 2005 to March 2006. A total of 192 healthy Wistar rats, weighing (200±20) g, of SPF grade, of both gender by half, were provided by Experimental Animal Center of Nanfang Hospital Affiliated to Southern Medical University. Tongxinluo was consisted of renshen, wugong, quanxie, shuizhi, chishao, bingpian, etc. and was provided by Shijiazhuang Yiling Pharmaceutical Co., Ltd. (batch number: 9906115). Main reagents: Agarose, DEPC-treated water, total RNA purification kit and one-step reverse transcription polymerase chain reaction (RT-PCR) kit were provided by Beijing Saibaisheng Gene Technique Co., Ltd. METHODS : All rats were randomly divided into 4 groups, including high-dosage Tongxinluo group, low-dosage Tongxinluo group, model group and sham operation group with 48 in each group. Rats in the former three groups were observed at 3, 5, 7, 14, 21 and 30 days after ischemia/reperfusion. In addition, rats in sham operation group were selected at the relevant time points. Every 8 rats were selected from each group for once. (1) Right middle cerebral artery occlusion-reperfusion models were induced by Koizumi method and modified; moreover, neurological impairment was evaluated with Zealonga method. Except rats in sham operation
