Objective To observe the effect of electroacupuncture on the expression of vascular endothelial growth factor receptor-2 (VEGFR-2) mRNA and brain-derived neurotrophic factor (BDNF) protein in brain tissue of rats with focal cerebral ischemia/reperfusion.Methods The focal cerebral ischemia/reperfusion model was established with filament occlusion. 90 rats were randomly divided into control group (n=6), model group (n=42) and electroacupuncture group (n=42). They were observed 2 h, 12 h, 24 h, 3 d, 7 d, 14 d, 21 d after ischemia/reperfusion, 6 rats in each points. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the expression of VEGFR-2 mRNA. Immunohistology method was used to detect the expression of BDNF protein. Results The expression of VEGFR-2 mRNA was higher in the electroacupuncture group than in the model group 12 h, 24 h, 3 d after reperfusion (P<0.05). The expression of BDNF protein in the hippocampus increased 2 h (P<0.05), reached peak 24 h (P<0.01) and still higher 3 d (P<0.05) in the electroacupuncture group than in the model group after reperfusion. Conclusion Electroacupuncture can upregulate the expression of VEGFR-2 mRNA and BDNF protein in brain tissue of rats with focal cerebral ischemia/reperfusion. Neuro-angiogenic factor is possibly the molecular basis of coordinated interaction of the nervous and vascular system.

Objective To understand and explore the personality characteristic of patients with migraine .To prevent and solve the health problems and provide scientific basis .Methods 100 patients with migraineurs were examined by self -edited question-naier and the Chinese version of the Minnesota Multiphasic Personality Inventory .86 effective questionnaiers which made up by 30 males and 56 females(aged from 18 to 65 ,46 years in average) were collected and analyzed .The subjects were grouped according to the gender ,and compared with the Chinese normal .Results In the male patients ,the measured scales of L ,HS ,D ,Hy ,Pd ,Pt and Ma appeared significantly higher than those in the normal males (P<0 .05) ,while in the female ,the measured scales of F ,Hs ,D , Hy ,Pa ,Pt and Ma appeared significantly higher than those in the normal females (P<0 .05) .Conclusion Patients with migraine have some changes in personality .Male patients and female patients were different .Eealy screening and intervention in the treatment of personality will help to improve the treatment of migraine effect .

Objective To investigate the relationship of plasma homocysteine with the genotype distribution of MTHFR and MTRR among Chinese Han women in Xiangtan. Methods MTHFR C677T, A1298C and MTRR A66G geno?typing was analyzed to detect the distribution of gene polymorphisms among 1 701 women from Xiangtan city then the data were compared with the rest of the Han women in Zibo, Zhengzhou, Yantai, Zhenjiang, Songzi, Huizhou, Qionghai. Plasma Hcy levels from 110 patients were measured and analyzed the correlation with gene polymorphisms. Results The frequency of MTHFR C677T genotype and allele frequencies in Xiangtan is 12.6%which is higher than Huizhou (10.9%) and Qionghai (6.1%) but lower than Zibo (43.6%), Zhengzhou (36.8%), Yantai (32.2%), Zhenjiang (21.8%) with statistically significant dif?ference (P<0.05). There is no significant different in MTHFR C677T between Xiangtan and Songzi. The frequency of MTH?FR A1298C genotype and allele frequencies in Xiangtan is 4.8%which is lower than Qionghai(7.1%)but higher than Zibo (1.4%),Zhengzhou(2.4%), Yantai(1.8%), Zhenjiang(3.5%)and Songzi(2.6%)with statistically significant difference. The frenquency of MTRR A66G genotype and allele frequencies in Xiangtan is 6.8%which is higher than Zibo (4.8%) but lower than Qionghai (9.3%) with statistically signifcant difference. Plasma Hcy concentration correlate with MTHFR C677T, Hcy concentration in TT population is higher than that in CT and CC population(μmol/L:8.52±2.01 vs 5.94±1.47 vs 5.71± 0.18);Plasma Hcy concentration also correlate with MTHFR A1298C and Hcy concentration in CC population is higher than AA and AC population(μmol/L:9.83 ± 2.26 vs 6.35 ± 2.13 vs 5.55 ± 1.75);Plasma Hcy concentration does not correlate with MTRR A66G. Conclusion The gene polymorphism of MTHFR C677T, A1298C and MTRR A66G among the Han women in Xiangtan was statistically different from other selected regions of China. Mutation in MTHFR C 677T and A1298C were associated with elevated plasma levels of Hcy.
5.Effect of Electroacupuncture at Hegu (LI04) on Capillary Density and Expression of CD34 after Focal Cerebral Ischemia/Reperfusion in Rats
Chinese Journal of Rehabilitation Theory and Practice 2014;(3):201-205
Objective To observe the effect of electroacupuncture at Hegu (LI04) on capillary density and expression of CD34 after focal cerebral ischemia/reperfusion in rats. Methods 90 rats were randomly divided into normal group (n=6), model group (n=42) and electroacupuncture group (n=42). A rat model of focal cerebral ischemia/reperfusion was made by filament occlusion in the model group and the electroacupuncture group. And the electroacupuncture group received electroacupuncture. They were observed 2 h, 12 h, 24 h, 3 d, 7 d, 14 d, 21 d after reperfusion 1 h followed ischemia. HE staining was used to observe and calculate the infarct volume and capillary density, and immunohistology was used to detect the expression of CD34 after neurologic symptoms rating. Results Compared with the model group, the neurologic symptoms score significantly decreased 2 h after reperfusion in the electroacupuncture group (P<0.01), and still decreased 21 d after reperfusion (P<0.05). The infarct volume significantly was smaller in the electroacupuncture group than in the model group (P<0.01). The capillary density was higher 2 h, 24 h, 3 d, 7 d, 14 d after reperfusion in the electroacupuncture group than in the model group (P<0.05). Compared
with the model group, the expression of CD34 significantly increased 3 d after reperfusion in the electroacupuncture group (P<0.01),and it reached a peak at 7 d after reperfusion (P<0.01), and still higher at 14 d. Conclusion Electroacupuncture can promote the expression of CD34 and the capillary density, and stimulate the angiogenesis after focal ischemia/reperfusion.
