Sheng-Xing Ma is a Professor and Director of Integrated Medicine Research Laboratories at Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center. He was recruited to UCLA as an Assistant Professor in 1996, and he received a promotion to Associate Professor in 2003 and Professor in 2008 in the Department of Obstetrics and Gynecology at UCLA David Geffen School of Medicine and Harbor-UCLA Medical Center. Dr. Ma has been engaged in the studies of nitrate pharmacology, biochemistry and physiological effects of nitric oxide (NO) for the past 20 years. He has demonstrated that nitroglycerin modifies neuronal excitability, increases norepinephrine release/synthesis in heart and brain, and stimulates noradrenergic activation in the posterior hypothalamus, which contributes to nitrate tolerance and central cardiovascular effects of the drug. Results from his group have found that NO mediates acupuncture-induced cardiovascular and analgesic effects through a novel pathway, the dorsal medullar-thalamic tract. Another novel discovery is that NO-cGMP related biomolecules contribute to biochemical physiological changes in acupoints associated with meridian practices and diseases. He has developed a painless, non-invasive device to biocapture NO, cGMP, and nitrotyrosine from skin surface of acupoints and meridians for studies of signal transduction molecules during physiological and pathological changes, and therapies such as acupuncture, moxibustion, and meditation/Qi Gon.

Sheng-Xing Ma, MD, PhD, associate professor at UCLA, David Geffen School of Medicine, summarizes "acupuncture point, 'St 36', decreases heart blood pressure and heart rate."5 He notes "L-arginine derived NO [nitric oxide] in the gracile nucleus and mNTS [medial portion nucleus tractus solitarius] mediates CV reflex responses to electro-stimulation at acupuncture point, 'St 36'."5 He describes the dorsal-medulla-thalamic tract to be the important pathway for acupuncture signals. Up-regulation of nNOS-NO [neuronal NO synthase] in the pathways mediates the non-opioid effects of electro-stimulation at acupuncture point, 'St 36'.6
Dr. Ma's research shows NO is generated from the skin surface with a high level existence at acupuncture points and possibly at meridians lines. Thus, Dr. Ma concludes NO modifies skin electricity which creates low resistance characteristics for acupuncture points, raises the conductance, increases signal flow and the therapeutic effect.
