Objective To study the effect of electrical stimulation of the fastigial nucleus of the cerebellum (FNS) on learning,memory and the expression of growth-association protein-43 (GAP-43) after cerebral ischemia and reperfusion.Methods Sixty healthy,adult,male Sprague-Dawley rats were randomly divided into a normal group,a sham-operation group (sham group),a model group and an FNS group,with 15 rats in each.Left middle cerebral artery occlusion and reperfusion (MCAO/R) was administered to the rats in the FNS and model groups using the thread embolism method.The rats of the FNS group were given FNS treatment using a pair of needle electrodes inserted into the cerebellar fastigial nucleus 3hrs after the MCAO/R.Needle electrodes were similarly inserted in the model group rats,but no electrical stimulus was applied.Then the rats' learning and memory abilities were tested using a Morris water maze on days 1,3 and 7 after the MCAO/R modeling.The expression of GAP-43 mRNA on the side of the cerebral infarction was detected using a quantitative,real-time polymerase chain reaction.Results The average escape]atencies of the rats in the model and FNS groups were significantly longer than those of the normal and sham groups at all time points,but the FNS group rats demonstrated a significantly shorter average escape latency than the rats of the model group at each time point.The normal and sham groups showed a significantly lower expression of GAP-43 mRNA than the model and FNS group rats at all time points.The FNS group rats had a significantly higher level of GAP-43 mRNA than the rats of the model group.Conclusion FNS improved the rats' learning and memory abilities.This might be associated with the up-regulation of GAP-43 mRNA in neurons on the side of the cerebral infarction which could promote the regeneration and repair of peripheral nerve axons in the area of the infarction.

BACKGROUND:Anterior cervical plate can maximize the intervertebral space height,expand intervertebral foramen,restore cervical physiological antecurvature,prevent instability due to implant micromovement,and increase graft fusion.However,the selection of entire autologous bone or Ti-mesh bone graft remains uncertain in application of anterior cervical plate.OBJECTIVE:To compare the complications of three different intervertebral fusion methods in anterior cervical decompression surgery.METHODS:A total of 92 cases of cervical spondylotic myelopathy were treated by anterior cervical decompression and three different intervertebral fusion methods.They were followed up for at least 3 months.Of them,6 underwent bone grafting alone,21 underwent autogenous bone graft with cervical plate-screw fixation,and 65 underwent pyramesh with anterior cervical plate-screw fixation.Complications were observed in all cases.RESULTS AND CONCLUSLON:A total of 2 of 6 autogenous bone grafting cases suffered from graft bone dislocation,1 suffered from pseudoarthrosis formation,and 1 suffered from donated ilium.Six of 21 autogenous bone graft with cervical plate-screw fixation suffered from loss of intervertebral height,and 3 suffered from pain of donated ilium.Eleven of 65 pyramesh with anterior cervical plate-screw fixation suffered from titanium mesh subsidence,1 case suffered from breakage of fixation screw.Simple autogenous bone grafting surgery was rarely used due to long duration of external fixation and too much complications.Autogenous bone grafting with anterior cervical plate-screw fixation surgery has shortage of grafted bone absorption and pain of donated ilium.Pyramesh with anterior cervical plate-screw fixation surgery overcomes the shortage of donated iliac pain,but remains the shortage of titanium mesh subsidence and lose of intervertebral height.

Objective To determine the contributions of main chemical compositions of extracts of Eucalyptus camaldulensis represented by GC/MS elute peaks to the molluscicidal activities,and explore a shortcut of looking for the effective components from natural products. Methods E. camaldulensis leaves were collected consecutively in 12 months at the same place,extracted with dichloromethane,analyzed by GC/MS,and their LC50(s)of molluscicidal activities were tested according to the method rec-ommended by WHO. The correlation of the main components in 12 extracts and their molluscicidal activities were analyzed by the grey relative correlation analysis model with software GTMS 3.0. Result All the dichloromethane extracts of eucalyptus leaves showed excellent molluscicidal activities with the highest LC50 of 0.257mg/L and 0.242mg/L for the samples in June and July and the lowest LC50 of 6.802 mg/L and 5.406 mg/L in December and January respectively. The structures of 16 main chemical compo-nents were elucidated by GC/MS and NIST Mass Spectral Library,most of which were monoterpenes and sesquiterpenoids. The gray correlation coefficients with activity were all over 0.5,the first five over 0.9 were 4,4,8-Trimethyltricyclo[6.3.1.0(1,5)]do-decane-2,9-diol,(-)-Spathulenol,a structural isomer of(-)-Spathulenol,Eucalyptol and Ledol. Conclusion The most main in-gredients in the dichloromethane extracts of E. camaldulensis leaves show good correlations with the molluscicidal activity,which suggests that the molluscicidal role is synergistically played by the multiple components together.
