Objective : To study the protective effects of two antioxidants on the influence of passive smoking on learning and memory ability of mouse offspring. Method: Passive smoking model of pregnant mice was established. Learning and memory ability was evaluated by water maze and long term potentiation (LTP). Nitric oxide (NO) content and nitric oxide synthase (NOS) activity of brain, vitamin E(VE) concentration and reactive oxygen species (ROS) of serum were determined. Results: Latency (the swimming time from beginning to endpoint) and errors (the number of entering blind end) in control and two antioxidant groups were shorter as compared with tobacco smoking (TS) group after 6 d in water maze test, and still shorter after 10 d in control and TS+VE groups. LTP was inhibited in TS group but increased significantly in two antioxidant groups. NOS activitiy was significantly higher in TS group in comparisonwith the control. NO content of TS+VE group was significantly lower than TS and TS+Q groups. Serum VE concentration and ROS level were correlated with the results of latency in water maze and LTP. Conclusion: Passive smoking of the pregnant mice may restrain LTP formation through disturbance of hippocampus function, and reduce the learning and memory ability of the offspring and VE may protect such effects.

For the effectiveness in disease treatment and prevention, traditional medicine (TM)has been widely used around the world. Many governments have accepted TM as part of their health system. Meanwhile, the regulation became strict. This paper analyzed the regulation mode of TM and Complementary & Alternative Medicine (CAM) in foreign countries. The regulation mode mainly included: independent legislation for TM, comprehensive legislation as CAM, and self-discipline regulation by trade association. We also analyzed the existing problems and prospected the developing trends in future.

Objective To investigate the effect of electroacupuncture(EA)on the expression of vasopressin type 2 receptor(V2R),aquaporin-2(AQP2)and epithelial sodium channel-α(ENaC-α)in guinea pigs with arginine vasopressin(AVP)-induced endolymphatic hydrops(EH).Methods Male albino guinea pigs were randomly divided into normal control,EH model and EA groups(n=12 guinea pigs in each group).The EH model was established by continuous injection intraperitoneally of AVP,4μg/(kg·d)for 7 days,and then 6μg/(kg·d)for 3 days,totally 10 days.EA(100Hz,1mA)was applied to Baihui(GV 20)and unilateral Tinggong(SI 19)for 20 min,once a day for continuous 10 days.Cochlear hydrops severity was measured using hematoxylin-eosin(HE)staining,and then the ratio of scala media(SM)area to SM + scala vestibuli(SV)area(R value)was calculated.The expression level of V2R,AQP2 and ENaC-α in the cochlea was detected by western blot.Results Following modeling,R value,the V2R,AQP2 and ENaC-α protein expression were significantly increased in comparison with the normal group(all P<0.01).After EA intervention,R value,the V2R,AQP2 and ENaC-α protein expression were notably down-regulated in comparison with the model group(all P<0.01).Conclusion EA can relieve the cochlear hydrops of EH guinea pigs,which may be related to its effect in down-regulating the expression of V2R,AQP2 and ENaC-α protein in the cochlea.

Objective:To evaluate the clinical effect of Guanxin Tongmai plaster combined with conventional western medicine in the treatment of phlegm and blood stasis syndrome of coronary heart disease and angina pectoris.Methods:A total of 60 patients in the Department of Cardiology of the Affiliated Hospital of Liaoning University of Traditional Chinese Medicine (TCM) from February to August 2020 who met the inclusion criteria were randomly divided into two groups with 30 in each group. Both groups were treated with conventional western medicine. On this basis, Guanxin Tongmai plaster was applied at the acupoints in the treatment group and placebo plaster was applied in the control group. TCM syndrome score was performed before and after treatment, angina score was evaluated from three aspects of angina attack frequency, duration and pain degree, and blood lipid TG, TC, LDL-C and HDL-C were detected by enzyme quantitative method. The blood homocysteine (Hcy) was detected by enzyme circulation method, the ECG and the nitroglycerin reduction rate were recorded, and the safety index was detected according to the ECG changes.Results:In the treatment period, 2 patients in the treatment group fell off, 3 in the control group. A total of 28 patients in the treatment group and 27 in the control group were analyzed. The total effective rate of ECG efficacy in the treatment group was 67.9% (19/28) and the control group was 48.1% (13/27). There was significant difference between the two groups ( χ2=4.46, P=0.040). After treatment, the TCM syndrome score and angina score in the treatment group were significantly lower than those in the control group ( t values were 9.12 and 4.45, P values were 0.004 and 0.042, respectively). The reduction rate of nitroglycerin in the treatment group was 82.1% (23/28) and 55.6% (15/27) in the control group. There was significant difference between the two groups ( χ 2=4.72, P=0.030). After treatment, the plasma TG, TC, LDL-C in the treatment group were significantly lower than those in the control group ( t values were 4.17, 6.57 and 6.52, P<0.05 or P<0.01), the level of HDL-C was significantly higher than that of the control group ( t=7.07, P=0.010), and the level of plasma Hcy was significantly lower than that in the control group ( t=6.70, P=0.012). There was no significant difference in liver, kidney and coagulation function between the two groups. Conclusion:Guanxin Tongmai plaster combined with conventional western medicine can improve the clinical symptoms of patients with coronary heart disease and angina pectoris, reduce the level of blood lipid and Hcy, and improve the clinical curative effect.
