Objective To investigate the effect of hand twelve Jing-Well points bloodletting on blood-brain barrier (BBB) permeability in the early stage of focal cerebral ischemic injury in rats with permanent middle cerebral artery occlusion (pMCAO). Method Male Wister rats were randomized into sham operation, model and bloodletting groups. A model of middle cerebral artery occlusion was made by Longa's method. 2%Evans blue (EB) was injected into the caudal vein at three time points:5, 24 and 72 hrs after model making. EB exudation amount was assessed by measurement of EB absorbance in brain tissue to observe BBB permeability. Result Cerebral EB exudation amount was significantly higher in the model group of rats than in the sham operation group (P<0.01) and significantly lower in the bloodletting group than in the model group (P<0.01). Conclusion Hand twelve Jing-Well points bloodletting can reduce blood-brain barrier permeability in pMCAO rats. Its effect is highly significant at 24 and 72 hrs after ischemia.

Objective To observe the subarachnoid space the epidural space joint block labor analgesia (CSEA) changes of T lymphocyte subsets.Methods 100 cases of full-term mothers were randomly divided into two groups,analgesia group and the control group.The analgesic group row CSEA childbirth analgesia.Two groups of maternal cervix large 2 to 3cm (T1),when the baby was delivered (T2),24h (T3),blood was colleoted after childbirth,detected by radioimmunoassay of cortisol.Flow cytometry assay was wsed to test T lymphocyte subsets CD3+,CD4+,CD8+,CD4+/CD8+,And the birth process,Apgar score,Labor pain visual analogue score (VAS) were recoroded.Results (1) Active phase of the first stage of childbirth analgesia group was significantly shorter than the control group (t =2.182,P ＜ 0.05).The second and third stage of Childbirth and neonatal Apgar score difference between the two groups was not statistically significant.(2)Serum cortisol concentration at T2 analgesia group was significantly lower that of than the control group (P ＜ 0.05).(3) The two groups in maternal blood of CD3+,CD4+,CD4+ / CD8+ were reduced to varying degrees,T3 was reduced significantly (P ＜ 0.05),Analgesia group was significantly lower than that of the control group (all P ＜ 0.05).Conclusion CSEA analgesia in Childbirth can shorten the first stage of Childbirth active period,has no significant effect on the Apgar score,can alleviate the pain and stress reactions such as the suppression of the maternal immune function.

Objective To investigate the calcium mechanism involved in the A? 25-35-induced neurotoxicity.Methods PC12 cells viability was detected by using MTT assay. Relative change of intracellular calcium concentration was measured by laser confocal microscope.Results MTT assay showed that the cell viability of the three groups (10 ?mol/L A? 25-35?10 ?mol/L A? 25-35+5 ?mol/L nifedipine?10 ?mol/L A? 25-35+10 ?mol/L nifedipine) was decreased by 34.5%, 25.1% and 11.0%,as compared with the control group. 10 ?mol/L nifedipine could protect PC12 cells from A? 25-35-induced damage. A? 25-35 of different concentration (0.1 ?mol/L, 1 ?mol/L, 10 ?mol/L, 20 ?mol/L and 30 ?mol/L) resulted in the elevation of intracellular calcium (about 6.38%, 6.42%, 62.2%, 69.3% and 107.5%) with a dose-dependent manner. Potassium (5 mmol/L, 15 mmol/L and 30 mmol/L) could increase the intracellular calcium after one minute pretreatment of different concentration A? 25-35. Both above mentioned actions were sensitive to the medium calcium and were antagonized by nifedipine, a L-voltage-gated calcium channel antagonist.Conclusion Soluble A? 25-35 may damage the neuronal calcium homeostasis in early stage and make neurons more vulnerable to physiological or pathological stimuli.

Objective To systemically evaluate the therapeutic effect of pramipexole in treating Parkinson's disease. Methods Pubmed, Embase, Cochrane Database were used to search for randomized control trials (RCTs) on Parkinson's disease treated with pramipexole. Meticulous data wre extracted and meta-analysis was performed according to a preset protocol. Results Ten RCTs involving 1738 patients were included. The results of meta-analysis showed that pramipexole decreased the total scores of unified Parkinson's disease rating scale [UPDRS, WMD=-10.01,95%CI (-12.76,-7.26)],UPDRS part [WMD=-2.44,95%CI(-2.93,-1.95)],and UPDRS partⅢ[WMD=-6.61,95%CI(-8.38,-4.84)]. Pramipexole also reduced the score of UPDRS part Ⅳ[WMD=-0.73,95%CI(-1.16,-0.30)] in advanced patients(P＜0.05＝.Three studies referred to the effect of pramipexole in treating parkinsonian tremor. However there was a clinical heterogeneity among the studies, and two of them revealed a significant difference. Conclusions Pramipexole might improve motor symptoms and the quality of life in advanced patients, as well as improve tremor, which needs more RCTs to be confirmed.

Objective To explore the immunomodulatory mechanism of 2-(-2-benzofuranyl )-2-imidazoline(2-BFI) in rat model of experimental autoimmune encephalomyelitis (EAE).Methods Fifty fe-male Sprague-Dawley(SD) rats were randomly divided into five groups by random digit table , including con-trol group(n=10), EAE model group(n=10), low dose 2-BFI group(1.5 mg/kg, n=10), median dose 2-BFI group (3 mg/kg, n=10) and high dose 2-BFI group (6 mg/kg, n=10).The SD rat model of EAE was induced by immunizing with a guinea pigs′spinal cord homogenate ( GPSCH ) .The severity of EAE was scored according to the signs and symptoms .Pathological changes were observed through Hematoxylin-eosin staining, and then the degrees of inflammatory infiltration were evaluated .The number of activated neuroglia that expressed GFAP and iba 1 in lumbar cords was counted by immunohistochemistry .The expressions of IL-1β, IFN-γ, IL-4 and IL-10 in cervical cords were measured by ELISA .Results Compared with EAE group, rats in the low, median and high dose 2-BFI treatment group had lower incidence of EAE , prolonged latency and decreased CNS inflammation , but only the median dose group showed significant alleviation in clinical symptoms and decrease in CNS inflammatory cell infiltration (P<0.05).Immunohistochemical re-sults showed that the numbers of activated microglia were significantly inhibited ,but the numbers of activated astroglia were increased in the rats treated with median dose of 2-BFI in comparison with the EAE group ( P<0.05).Results of ELISA demonstrated that expressions of IL-1βand IFN-γin 3 mg/kg 2-BFI treated group were significantly decreased compared with that in the EAE group (P<0.05), but expressions of IL-4 and IL-10 were remarkably increased(P<0.05).Conclusion 2-BFI at median dose of 3 mg/kg has a benefi-cial neuroprotective effect on rats with EAE , and its mechanism might be related to immunodulation .
