[Effect of Electroacupuncture Stimulation of Heart and Lung Meridians on Expression of Myocardial HCN 2 in Acute Myocardial Ischemia Rats].

Objective: To observe the effect of electroacupuncture (EA) stimulation of Heart and Lung meridians on the expression of hyperpolarization-activated cyclic nucleotide gated potassium channel 2 (HCN 2) mRNA and protein in the myocar-dium of the left ventricle in acute myocardial ischemia (AMI) rats, so as to underlying its mechanism in improving ischemic myocardial injury.

Methods: A total of 120 male SD rats were randomly divided into normal control, model, EA-Heart Meridian (HT) and EA-Lung Meridian (LU) groups (＝30 rats in each group). The AMI model was established by occlusion of the anterior descending branch of coronary artery.

[Effect of Different Concentrations of Moxa-smoke on Lung Function and TNF-α and IL-1 β Levels in Serum and Lung Tissues in Normal Rats].

Objective: To study the effect of moxa-smoke inhaling on the respiratory system, so as to provide experimental data and theoretical basis for evaluating the safety of moxa-smoke inhaling during moxibustion treatment.

Methods: A total of 48 SD rats were randomized into control, low, medium and high moxa-smoke-concentration groups (＝12 in each group). The low, medium and high concentrations of smoke were controlled in (0.
