摘要:Objective To find out the protective mechanism of electroacupuncture in senile cerebral ischemia and reperfusion(I/R) lesion based on the proliferation and differentiation of endogenous neural stem cells in dentate gyrus(DG).Methods The rat model of cerebral ischemia was established by using the method of middle cerebral artery occlusion(MCAO).All rats were divided into the sham-operation group,model group,non-acupoint treatment group and acupoint treatment group.The immunohistochemistry assay was applied to detect the positive neuron count of bromodeoxyuridine(BrdU),neuronal nuclei,(NeuN) and glial fibrillary acid protein(GFAP) in DG.The changes of cerebral pathology,water content,integrals of neural symptoms,and cell proliferation and differentiation in DG were observed at different time points,i.e.cerebral ischemia for 3 hours,and reperfusion for 1,3,7 and 12 days respectively.Results In the model group the cerebral water content(at all time points),integrals of neural symptoms(at all time points),BrdU positive neurons(at all time points),BrdU/NeuN doubly labeled positive neurons(I/R for 3,7 and 12 d) and BrdU/ GFAP doubly labeled positive neurons(I/R for 7 and 12 d) were higher than those in the sham-operation group.There was no significant difference in all indexes between the model group and non-acupoint treatment group at all time points.In the acupoint treatment group the cerebral water content(I/R for 1,3 and 7 d),integrals of neural symptoms(I/R for 3,7 and 12 d) and BrdU/GFAP doubly labeled positive neurons(I/R for 7 and 12 d) were lower than those in the model group and non-acupoint treatment group,and BrdU positive neurons(at all time points) and BrdU/NeuN doubly labeled positive neurons(at all time points) were higher than those in the model group and non-acupoint treatment group.Conclusion The proliferation and differentiation of endogenous neural stem cells in DG can be stimulated by cerebral ischemia.The mechanism of electroacupuncture in acupoints against cerebral ischemia and reperfusion lesion may be related to that electroacupuncture can improve the proliferation and differentiation of endogenous neural stem cells in DG.

摘要:Objective To study the influences of Ganxinning Decoction on protein expressions of α-smooth muscle actin(α-SMA),matrix metalloproteinase-13(MMP-13) and tissue inhibitor of metalloproteinase-1(TIMP-1) of liver tissue in rats with hepatic fibrosis.Method All male SD rats(n=68) were randomly divided into the normal group,model group,colchicines group,high-dose Ganxinning Decoction group and low-dose Ganxinning Decoction group.The rat model of hepatic fibrosis was established by the hypodermic injection of carbon tetrachloride(CCl4) and feeding by high-fat low-protein feed and 30% alcohol.At the end of the 6th week the expressions of α-SMA,MMP-13 and TIMP-1 were detected by using immunohistochemical stain method.Result The expressions of α -SMA and TIMP -1 decreased significantly in high -dose Ganxinning Decoction group,low -dose Ganxinning Decoction group and colchicines group compared with those in the model group(P<0.05).The expressions of α-SMA and TIMP-1 decreased significantly in high-dose Ganxinning Decoction group and low-dose Ganxinning Decoction group compared with those in colchicines group(P<0.05).The expression of MMP-13 in high-dose Ganxinning Decoction group,low-dose Ganxinning Decoction group and colchicines group increased significantly compared with that in the model group(P<0.05).The expression of MMP-13 in high -dose Ganxinning Decoction group and low -dose Ganxinning Decoction group increased significantly compared with that in colchicines group(P<0.05).Conclusion The inhibitory effect of Ganxinning Decoction on hepatic fibrosis may be related to that it can reduce the protein expressions of α-SMA and TIMP-1,and promote MMP-13 expression.
