My research interests are to investigate the mechanisms of cardiac sympathetic afferents activation and the associated central nervous system (CNS) reflex processing as well as modulation of electroacupuncture (EA) on CNS regulation of cardiovascular function. Studies of cardiac afferents activation are funded by a NIH grant (serve as CO-PI ). In these studies, I am investigating the mechanisms of activation and sensitization of cardiac afferents induced by multiple ischemic mediators including endothelins, thromboxane A2, 5-hydroxytryptamine (5-HT), histamine, lactic acid (protons), reactive oxygen species and bradykinin (BK), which stimulate and/or sensitize cardiac spinal afferents during ischaemia and reperfusion in an interactive and multifactorial fashion. I am also studying the mechanisms underlying CNS reflex processing evoked by ischemic metabolites during myocardial ischemia.

With respect to studies of the mechanisms of EA-modulated CNS regulation of cardiovascular function, funded by another NIH grant (as CO-investigator), I am studying the neurotransmitters dynamic mechanisms in the cardiovascular regulating centers of the brain including hypothalamus, midbrain and medulla, underlying modulation of EA on visceral sympathoexcitatory reflexes induced by chemical and mechanic stimuli. Currently, I am defining the mechanism of EA modulates sympathoexcitatory reflex responses through inhibition of the midbrain ventrolateral periaqueductal gray (vlPAG) release of ?-aminobutyric acid (GABA), but not glutamate, through presynaptic cannabinoid CB1 receptor mechanism.
