Objective To investigate the effects of Buyang Huanwu decoction and its decomposed recipes on neurological function and angiogenesis after focal cerebral ischemia in rats and its mechanism. Methods Fifty-two clean grade SD male rats were randomly divided into sham-operation,model,whole prescription,invigorating qi,and promoting blood circulation groups (n = 8 in each group)according to the random number table. In addition to the sham-operation group,the middle cerebral artery occlusion models of the rats in other groups were induced by the suture method. The patients with the first Longa nerve function scores 1 to 3 were used as successful modeling. The whole Buyang Huanwu decoction included dried root of Astragalus membranaceus 120. 0 g,dried root of angelica sinensis 6. 0 g,dried root of Paeonia lactiflora 4. 5 g, dried rhizome Ligusticum chuanxiong 3. 0 g,dried body of Pheretima aspergillum 3. 0 g,dried flowers of Carthamus tinctorius 3. 0 g,and seed of Prunus persica 3. 0 g;the invigorating qi prescription included dried root of Astragalus membranaceus 120. 0 g;the promoting blood circulation prescription included dried root of angelica sinensis 6. 0 g,dried root of Paeonia lactiflora 4. 5 g,dried rhizome Ligusticum chuanxiong 3. 0 g, dried body of Pheretima aspergillum 3. 0 g,dried flowers of Carthamus tinctorius 3. 0 g,and seed of Prunus persica 3.0 g. On the first day after procedure,the rats began to be administered intragastrically. The intragastric doses of the whole prescription group,invigorating qi group,and promoting blood circulation group were 13. 1,10. 8,and 2. 2 g/ kg,respectively. The sham-operation group and the model group were given equal volume of isotonic saline,once a day for 14 days. 5-bromodeoxyuridine (BrdU,50 mg/ kg)were injected intraperitoneally,once a day for 14 days. The modified neurological severity score (mNSS)and the corner test were used to evaluate sensorimotor function at day 1,7 and 14 after procedure. BrdU and rat von Willebrand factor (vWF)double immunofluorescent staining were used to detect the angiogenesis in ischemic peripheral region;Western Blot was used to detect the protein expression of vascular endothelial growth factor (VEGF). Results (1)Compared with the model group,the mNSS score in rats in the whole prescription group was lower at day 7 and 14 after procedure (6. 8 ±1. 0 vs. 8. 5 ±1. 1,6. 1 ± 0. 8 vs. 8. 0 ± 1. 4;all P < 0. 01). The number of turning right in the whole prescription group was reduced (7. 1 ±0. 6 vs. 8. 6 ±1. 2 and 6. 1 ± 0. 8 vs. 7. 9 ±1. 1;all P < 0. 01). The number of turning right in the invigorating qi group was reduced (7. 5 ± 0. 5 vs. 8. 6 ± 1. 2 and 6. 2 ± 1. 0 vs. 7. 9 ± 1. 1;all P < 0. 01). At day 14 after procedure,the number of BrdU / vWF co-labeled immunopositive cells in ischemic peripheral zone of the whole prescription group was increased significantly. There was significant difference between the groups (30 ± 8 / mm2 vs. 24 ± 7 / mm2;P < 0. 01). The VEGF protein expression was increased (0. 33 ±0. 01 vs. 0. 30 ±0. 01;P <0. 01). (2)Compared with the invigorating qi group,the rat mNSS scores of the whole prescription group were lower at day 7 and 14 after procedure (the invigorating qi group 8.2 ±1.3 and 7.5 ±0.9 respectively;all P <0. 05). The number of BrdU/ vWF immunopositive cells in the whole prescription group was increased at day 14 after procedure (26 ±5/ mm2 in the invigorating qi group;P < 0. 05). The VEGF protein expression was increased (0.31 ±0.01 in the invigorating qi group;P <0.01). (3)Compared with the promoting blood circulation group, the mNSS scores of the whole prescription group were lower at day 7 and 14 after procedure (the promoting blood circulation group 8.5 ±0.9 and 7.6 ±0.7 respectively;all P <0. 05). The number of turning right was reduced (8.5 ±0. 8 and 7. 6 ± 0. 9 respectively in the promoting blood circulation group;all P < 0. 05). The number of BrdU/ vWF immunopositive cells in ischemic peripheral zone of the whole prescription group at day 14 after procedure was increased (26 ± 6 / mm2 ,P < 0. 05). The relative expression level of VEGF was increased (0. 31 ±0. 01 in the promoting blood circulation group,P <0. 05). Conclusion Buyang Huanwu decoction can promote angiogenesis and recovery of neurological function after cerebral ischemia. Its mechanism may be associated with the up-regulation of the VEGF protein. The traditional Chinese medicines for invigorating qi and invigorating the circulation of blood in the prescription have synergistic effect.

Objective To explore the relationship between PIAS3 expression and the degree of malignancy of meningiomas.Methods 72 cases of different degree of malignant meningioma and 13 cases of surgical specimens of normal brain tissue were extracted the total RNA,and detected the levels of PIAS3 in different degree of meningioma and normal brain tissue through comparative control study by using real-time fluorescence quantitative PCR.Results PIAS3 was low expressed in normal brain tissue,however,high expressed in the human brain meningioma with significant differences(P＜0.01).There were also significant differences found in expression level of PIAS3 between meningiomas grade I and Ⅱ,or Ⅲ level(P＜0.05),but the differences between meningiomas grade Ⅱ and Ⅲ were not obvious(P＞0.05).And PIAS3 expression was not related with the depth of infiltration in invasive meningiomas(P＞0.05).Conclusion PIAS3 was overexpression in meningiomas,and was be closely related to the occurrence and development of meningiomas.

Objective To explore the effect of depakine in the treatment of traumatic epilepsy relapse,and compared carbamazepine and lamotrigine combined with depakine in the treatment of traumatic epilepsy.Methods Open trial in 131 patients with traumatic epilepsy relapse treated with depakine,and all patients were aderministered with carbamazepine or lamotrigine combined with depakine.3 months before treatment,the epilepsy seizures frequency was compared,and 6 months after the treatment,the efficacy,adverse reactions and safety was compared between two mothods.Results Application of carbamazepine or lamotrigine combined with depakine treatment for 6 months,the seizure frequency significantly decreased compared with before treatment;The seizure frequency reduction( ≥50％ ) were 72.6％ and 91.3％,the difference was statistically significant between before and after treatment( P ＜ 0.01 ) ;The adverse reactions of carbamazepine combined with depakine was 37.1％,and it of lamotrigine combined with depakine was 8.7％.Conclusion Lamotrigine combined with depakine in the treatment of traumatic epilepsy recurrence was effective,and its side effects was light.

Objective To study the expression of aquaporin-4 (AQP-4) in core and marginal region of the contusion brain tissues from patients with severe traffic brain injuries. Methods Thirty patients with severe traffic brain injuries (frontal-temporal brain contusion) admitted into our department from January 2007 to July 2009 were enrolled in the study and divided into three groups according to the period from injury to operation, ie, 0-4 hours (Group A), 5-8 hours (Group B) and 9-12 hours (Group C). The tissue was collected from core and marginal regions of brain contusion in each group. Ten parts of normal brain tissues obtained from the cerebellum to gain good exposure of CPA region tumors were used as control. The expression of AQP-4 in the normal brain tissues and in the tissues from core and marginal region of brain contusion, with GAPDH used as a control. Results The expression of AQP-4 in the marginal region was distinctly higher than that in normal tissues and in the tissues from core region. The AQP-4 expression in the tissues of the core region was lower than that in normal tissues. Conclusions AQP-4 is highly expressed in the tissues from the marginal region early after injury in a time-dependent fashion. Low expression level of AQP-4 in the core region is possibly correlated with early damage of blood brain barrier and peripheral structures.
