Abstract:
Objective To investigate the in vitrointervening effect of ratserum effector substances on vascular endothelial cell proliferation and migrationafter stasis-eliminating and meridian-unblocking moxibustion and explore the possible proangiogenic mechanism of stasis-eliminating and meridian-unblocking moxibustion treatment for vascular dementia.Method Male adult Wistar rats were used.Arat model ofvascular dementia was made by four-vessel occlusion(4-VO).The rats were randomized to moxibustion,Western medicationand model groups.Asham operation group was established as a control.There was a total of four groups.The moxibustion group received aconite cake moxibustion on point Baihui(GV20)and suspended moxibustion on points Dazhui(GV14)and Shenting(GV24) and the Western medication, an oralgavage of aniracetam tablets.Treatment was given 15 days as one course for a total of two courses.Blood was taken from the Orbital cavity in the moxibustion, sham operation and model groups after each course of treatment.After stasis-eliminating and meridian-unblocking moxibustion, animal serum was prepared tointervene in human umbilical vein endothelial cell (HUVEC-12) culture.Another parallel liquid group was set up. RPMI-1640 culture medium containing 10% fetal bovine serum (FBS) was prepared.Endothelial cell proliferationwas examined bymethyl thiazolyl tetrazolium (MTT) colorimetric assay.Endothelial cell migration was examined by cell scratch labeling.Result After two courses of treatment, the examination of endothelial cell proliferation by methyl thiazolyl tetrazolium (MTT) colorimetric assay showed that rat serum intervened significantly in human umbilical vein endothelial cell (HUVEC-12) proliferation in the moxibustion serum group compared with the model serum, sham operation serum and parallel liquid groups (P<0.01).At 24 hrs after two courses of treatment, the examination of endothelial cell migrationby cell scratch labelingshowed that rat serum intervention significantly increased the HUVEC-12 migration rate in the moxibustion serum group compared with the model serum, sham operation serum and parallel liquid groups (P<0.01).Conclusion Stasis-eliminating and meridian-unblocking moxibustion has a marked improving effect on vascular endothelial cell proliferation and migration in vascular dementiarats, which provides strong evidence for its in vitro proangiogenic effect.
