Objective To investigate the effects of basic fibroblast growth factor (bFGF) on global cerebral ischemia/reperfusion (I/R) injury.Methods Twenty-four rabbits of both sexes aged 6 months weighing 2.2-3.0 kg were randomized into 3 groups ( n = 8 each) : group I sham operation; group Ⅱ I/R and group Ⅲ I/R + bFGF. The animals were anesthetized with diazepam, haloperidol and fentanyl. The right femoral artery was cannulated for BP monitoring and blood-letting. The animals were tracheotomized and mechanically ventilated (VT = 8 ml ?kg -1 , RR = 40 bpm, I: E = 1:2). PET CO2 was maintained at 40 mm Hg. Global cerebral I/R was induced by "occlusion of four vessels + hypotension" . Bilateral common carotid arteries and vertebral arteries were occluded for 30 min combined with hypotension, which was produced by blood-letting and maintained at 50%-60% of the baseline level. The four vessels were then released for reperfusion and BP was returned to baseline level by retrieval of the removed blood. In sham operation group ( Ⅰ ) the four blood vessels were exposed but not occluded. In group Ⅲ a loading dose of 30 ?g?kg-1 bFGF was given Ⅳ at the end of 30 min ischemia followed by bFGF infusion at 10 ?g? kg-1? h-1 for 6 h. In I/R group ( Ⅱ ) normal saline was given IV instead of bFGF. Blood samples were taken before I/R (T0 , baseline) and at 0, 0.5, 1, 3, 6 h (T1-5) of reperfusion for determination of serum neuron specific enolase (NSE) and S-100B concentrations. At the end of the experiment the animals were killed and brains removed for determination of brain water content and microscopic examination. Results Serum NSE and S-100B concentrations in group Ⅱ and Ⅲ were significantly increased at T4 5 as compared to the baseline (T0) and were significantly higher at T4 5 than those in sham operation group ( Ⅰ ) . Serum NSE and S-100B concentrations were significantly lower in group Ⅲ (I/R + bFGF) than in groupⅡ (I/R). Serum NSE and S-100B were positively correlated ( r = 0.736, P

BACKGROUND: It is manifested in epidemiology and clinical observation that lipoprotein (a) is a new risk factor of cerebrovascular disease and is closely related to cerebral ischemic stroke.OBJECTIVE: To discuss the relationship between levels of high serum lipoprotein (a) and stroke.DESIGN: Case controlled analysis.SETTING: Neurological Institute of Xiangya Hospital of Central South University.METHODS: Totally 294 patients with stroke were selected from Neurological Department of Xiangya Hospital of Central So, uth University between September 1999 and March 2002. Of them, 159 cases were regarded as cerebral infarction group and other 135 cases as acute hypertensive cerebral hemorrhage group. In cerebral infarction group, 109 patients had atherosclerotic cerebral infarction and 50 patients had lacunar cerebral infarction, and 94patients with contimuous health examination were regarded as health examination group. Serum lipoprotein (a) in each group was assayed with "sandwich enzyme-linked immuno-sorbent assay". According to whether the value of lipid was normal or not, patients with atherosclerotic cerebral infarction and acute hypertensive cerebral hemorrhage were divided into two groups. Comparisons between the two groups were assayed with single sample t test, and multiple liner regression was used to assay whether sex, hypertension and value of lipid were related to the level of serum lipoprotein (a).MAIN OUTCOME MEASURES: ① Comparisons of serum lipoprotein (a)among atherosclerotic cerebral infarction group, lacunar cerebral infarction group, acute hypertensive cerebral hemorrhage group and health examination group. ② Correlated analysis between serum lipoprotein (a) and lipid.RESULTS: Among 294 patients, 94 cases in control group entered the final analysis. ① Comparisons of serum lipoprotein (a) among atherosclerotic cerebral infarction group, lacunar cerebral infarction group, acute hypertensive cerebral hemorrhage group and health examination group: Levels of serum lipoprotein (a) in atherosclerotic cerebral infarction group and cerebral hemorrhage group were higher than those in health control group (P < 0.05), and concentration of lipoprotein (a) in atheroosclerotic cerebral infarction group was increased as compared with that in acute hypertensive cerebral hemorrhage group (P < 0.05). Also, level of lipoprotein (a) in lacunar cerebral infarction group was a little higher than that in control group,but the difference was not significant (P > 0.05). ② Correlated analysis between serum lipoprotein (a) and lipid: Levels of lipoprotein (a) in both normal lipid group and abnormal lipid group were assayed with single sample t test, and the results showed that levels in the two groups were similar (P > 0.05). Multiple liner regression was used to assay whether sex,hypertension and value of lipid were related to level of serum lipoprotein (a).CONCLUSION: Levels of lipoprotein (a) may be an independent risk factor for cerebral hemorrhage and atherosclerotic cerebral infarction.
