Objective To investigate the possible mechanism of the gap junctional influence on the change in permeability of the blood-brain barrier(BBB)after reperfusion subsequent to cerebral ischemia.Methods In the test laser scanning confocal microscope(LSCM)was used to investigate the change of Cx43 levels and distribution.The MCAO/R model was induced using intraluminal suture technique first described by Longa with a little modification.A total of 60 Wistar rats were divided into 4 groups:the sham-operation group,control group,octanol-treatment group and DMSO vehicle control group. Control group were further divided into seven subgroups at different time points of reperfusion after middle cerebral artery occlusion.To observe the change in permeability of BBB,Evans blue(EB)in the brain tissue was surveyed by the means of EB fluorescent quantitation.Octanol-treatment group and DMSO vehicle control group were done at the point of the peak of permeability of BBB.Octanol,the specific blocker for gap junctions(GJ)was used in an intervention study.To compare the amount of EB with the same point of groups,the influence of octanol on BBB permeability was investigated.Results At 3 h of reperfusion after cerebral ischemia for 2 h,the permeability of BBB began to increase,reached the peak at 24 h of reperfusion and was still elevated at 72 h.The Cx43 expression formed into bigger plague and remained linear disposition in the penumbra after reperfusion subsequent to cerebral ischemia.Octanol group was done at 24 h of reperfusion after cerebral ischemia.The amount of EB of octanol group((4.924?0.296)?g/g)was significantly lower than that of corresponding operation control group(5.543?0.506)?g/g.Conclusions (1)Cx43 expression is concentrated around vessels in brain.The Cx43 forms into bigger plague and the function maybe strengthens after reperfusion.Gap junction might aggravate the disruption of BBB.(2) Octanol,the specific blocker of gap junctions,could effectively prevent the permeability of BBB from increasing and has a protective effect on BBB.

OBJECTIVE:To compare the efficacy and safety of Jinkui shenqi pill versus Shengjing capsule in the treatment of oligoasthenozoosperimia under behavioral intervention. METHODS:98 patients with oligoasthenozoosperimia were randomly divid-ed into Shengjing capsule group(49 cases)and Jinkui shenqi pill(49 cases). All patients received intervention treatment(cognitive intervention,psychological intervention,diet intervention and exercise intervention,etc.). Based on it,Shengjing capsule group re-ceived 1.6 g Shengjing capsules,orally,3 times a day;Jinkui shenqi pill group received 6 g Jinkui shenqi pill,orally,twice a day. They were treated for 3 months. Clinical efficacy,semen quality (semen volume,sperm concentration,sperm motility rate, sperm motility)and sex hormone levels [testosterone(T),follicle stimulating hormone(FSH),luteinizing hormone(HLH),pro-gesterone(P),prolactin(PRL)] before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RE-SULTS:The total effective rate in Shengjing capsule group was significantly higher than Jinkui shenqi pill group,with statistical significance(P<0.05). Before treatment,there were no significant differences in semen quality and sex hormone levels(P>0.05). After treatment,semen quality in 2 groups was significantly higher than before,semen volume and sperm motility in Shengjing cap-sule group were higher than Jinkui shenqi pill group,with statistical significances(P<0.05). T levels in 2 groups were significant-ly higher than before,while Shengjing capsule group was lower than Jinkui shenqi pill group,with statistical significances (P<0.05);and there were no significant differences in FSH,HLH,P and PRL before and after treatment in 2 groups(P>0.05). And there was no significant difference in the incidence of adverse reactions(P>0.05). CONCLUSIONS:Under behavioral interven-tion,Shengjing capsule has better efficacy than Jinkui shenqi pill in the treatment of oligoasthenozoosperimia,it can significantly improve semen quality,while Jinkui shenqi pill is better in terms of improving sex hormone levels;and both show good safety.
