Abstract:
ObjectiveTo investigate the effect of heart-regulating and mind-calming acupuncture on the expression of gap junction protein connexin43 (Cx43) in myocardial cells in a rabbit model of ventricular arrhythmia.MethodA rabbit model of ventricular arrhythmia was made by injecting barium chloride into the marginal ear vein. Forty New Zealand rabbits were randomized into control, model, acupuncture and medication groups. The acupuncture group received heart-regulating and mind-calming acupuncture[at Lingtai(GV10), Shendao(GV11), bilateral Neiguan(PC6)and Baihui(GV20)]and the medication group, oral gavage of propafenone. Rabbit left ventricle was taken after the completion of the experiment. Cx43 expressions were compared and analyzed usingan immunohistochemical staining technique and a computer image processing system.ResultCx43 expression decreased significantly in the model group compared with the control group (P<0.01) and increased in the acupuncture and medication groups compared with the model group (P<0.05). There was no significant difference in Cx43 expression between the acupuncture and medication groups (P>0.05).Conclusion Adjusting Cx43 expression in myocardial cells may be one of the target points for this acupuncture treatment of arrhythmia.
