ABSTRACT
Objective To study the effect of recombinant human platelet activating factor acetylhydrolase (rPAF-AH) on candidate plasticity-related gene 15 (CPG15) expression in focal cerebral ischemia rats.Methods Forty-five SD rats were randomly divided into sham operation group,saline group and rPAF-AH group (15 in each group).A middle cerebral artery occlusion model of rats was established for the latter two groups.Each group was divided into 2 d group,7 d group,14 d group.Five rats in each of 2 d group,7 d group,14 d group were used in experiment.The total protein was extracted from coronary sections using homogenate.CPG15 protein expression was detected by Western blot.Results The CPG15 protein expression level was significantly higher in saline group and rPAF-AH group than in sham operation group on days 2,7,14 and reached its peak on day 7,and in rPAF-AH group than in saline group on day 7 (1.48±0.04 vs 1.12±0.05,P＜0.01).Conclusion PAF-AH plays a positive role in neuroplasticity of cerebral ischemia by upregulating the CPG-15 expression in focal cerebral ischemia rats.
ABSTRACT
Objective To evaluate the clinical curative effect of Salvia miltiorrhiza Ligustrazine combined with Butylphthalide in cerebral infarction of children. Methods Sixty-two children with acute cerebral infarction were randomly divided into treatment group (33 patients) and control group (29 patients). The patients in two groups received the same basic treatment. The control group used Salvia Ligustrazine injection, and the treatment group used Salvia Ligustrazine injection combined with Butylphthalide. The total efficiency, the degree of recovery of muscle strength and the scores of nerve defect 2 weeks after treatment were compared. Results The total efficiency in treatment group was 87.9%(29/33), in control group was 75.9%(22/29), and there was significant difference (P<0.05). Two weeks after treatment, the muscle strength scores in treatment group was (4.00 ± 0.47) scores , in control group was (3.59 ± 0.98) scores, and there was significant difference (P<0.05). Two weeks after treatment, the scores of nerve defect in treatment group was (5.42 ± 2.18) scores, in control group was (6.86 ± 2.23) scores, and there was significant difference (P<0.05). Conclusions Salvia Ligustrazine combined with Butylphthalide in treatment of cerebral infarction of children has obvious effect, and it is worthy of spreading.
