Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of the outbreak of coronavirus disease 2019 in Wuhan City, China. The SARS-CoV-2 is genetically similar to the coronavirus derived from bat. The SARS-CoV-2, the SARS-CoV and the Middle East respiratory syndrome coronavirus (MERS-CoV) all belong to beta coronavirus. Since the outbreak of the coronavirus disease 2019, effective antiviral drugs have become a hot issue in the world. Very little about SARS-CoV-2 is known and there is no precedent for treatment. The National Health Commission has repeatedly revised the diagnosis and treatment guide for the coronavirus disease 2019. The latest guide is "New Coronary Virus-Infected Pneumonia Diagnosis and Treatment Plan (Seventh Trial Version)"(short for Seventh Version of Diagnosis and Treatment Plan). But the use of antiviral drugs is still on trial and no rigorous clinical trials data is available. Hot anti-SARS-CoV-2 drugs include interferon α, ribavirin, lopinavir/ritonavir, chloroquine phosphate, abidol, as well as hydroxychloroquine sulfate and remdesivir. But the later 2 drugs aren't mentioned in the Seventh Version of Diagnosis and Treatment Plan.

ObjectiveTo observe the effects of electroacupuncture at Zhongwan (CV12) on gastric nociceptive response induced by gastric acid stimulation and explore the underlying mechanisms associated with nuclei of the medullary viscerosensory and visceral motor neurons. MethodsTwenty SD rats were given intragastric administration of 0.5 mol/L diluted hydrochloric acid (0.5 ml/100 g) to induce gastric nociceptive response induction. Eight rats were randomly selected to record the gastric slow wave (GSW) area under the curve, and extracellular discharge frequency of neurons in the nucleus of the solitary tract (NTS) and dorsal motor nucleus of the vagus nerve (DMV) before intragastric administration and at 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, and 60 minutes after intragastric administration. The remaining 12 rats received electroacupuncture intervention at Zhongwan within 5 to 25 minutes after intragastric administration of diluted hydrochloric acid, with a duration of one minute. The GSW area under the curve and extracellular discharge frequency of NTS and DMV neurons were compared between the 1-minute intervals before and after electroacupuncture intervention. ResultsCompared to the baseline before intragastric administration, the area under the curve of GSW significantly increased at 1, 5, 10, 15, 20, and 25 minutes after intragastric administration, and the extracellular discharge frequency of excitatory neurons in the NTS (accounting for 90%, 57/63) significantly increased at 1, 5, 10, 15, 20, 25, 30, 35, and 40 minutes, both reaching peak values at 1 minute after intragastric administration (P<0.01 or P<0.05). The extracellular discharge frequency of inhibitory neurons in the DMV (accounting for 91%, 20/22) showed a non-significant increase at 1 minute after intragastric administration (P>0.05), but significantly decreased at other timepoints (P<0.05). Compared to the baseline before electroacupuncture intervention, the GSW area under the curve and the extracellular discharge frequency of excitatory neurons in the NTS significantly decreased (P<0.05), while the extracellular discharge frequency of inhibitory neurons in the DMV showed no significant difference (P>0.05). ConclusionElectroacupuncture at Zhongwan can improve gastric nociceptive response induced by gastric acid stimulation, possibly by reducing the transmission of visceral sensation and decreasing the excitability of NTS neurons in the medulla.
