Objective: To study the health effects of selenium tea on cardiovascular system. Methods : Four groups of Wistar rats were fed standard diet and water, standard diet and selenium tea , high fat diet and water ,high fat diet and selenium tea respectively. Twelve weeks later, the plasma apoA , apoB, body weight, whole blood viscosity , plasma viscosity , and hematorcrit were determined while plasma fibrinogen and inhibition of erythrocyte aggregation were calculated. Results: At the end of the experiment ,the plasma apoA level of selenium tea groups was significantly higher than that of control group, while the ratio of apoB/apoA was significantly lower than that of control group. Selenium tea decreased the whole blood viscosity, plasma viscosity and inhibited erythrocyte aggregation and body weight. Conclusion: Selenium tea could significantly improve the lipoprotein metabolism and hermorrheology and decrease body weight of the rats fed high fat diet.

OBJECTIVETo observe the effect of electro-needling at acupoints of the yangming meridian on the expression of platelet associated complement-1 (PAC-1) and lower limb functions in acute cerebral infarction (ACI) patients.

METHODS58 ACI patients were randomly assigned to the treatment group and the control group. Conventional therapies were given to all patients. Additionally, the electro-needling at acupoints of the yangming meridian was given to patients in the treatment group. Changes of PAC-1 were detected using flow cytometry. Effect of lower limbs functions of ACI patients before and after electro-needling was assessed using Fugl-Meyer Index. Meanwhile, 20 healthy subjects were selected for reference value.

RESULTSIn the acute stage, the PAC-1 level in ACI patients were significantly higher than that in healthy subjects (P<0.05). The PAC-1 level in the electro-needling group was obviously lowered after treatment (P<0.01). There was no significant difference in the control group between before and after treatment. Significant difference was found in Fugl-Meyer index in the same group between before and after two-week treatment (P<0.05). It was higher in the electro-needling group than in the control group, showing significant difference (P<0.01).

CONCLUSIONSPlatelet activation exists in the acute stage of ACI. Electro-needling at acupoints of the yangming meridian showed obvious inhibition on PAC-1 levels, could improve lower limbs functions of ACI patients. It was inferred that electro-needling at acupoints of the yangming meridian promoted the recovery of paralyzed lower limbs at the early stage mainly by regulating PAC-1 levels, thus postponing the progress of ACI.

Objective To investigate the effect of optimizing protocol activity on the cardiac function in patients with hypertension.Methods One hundred and one patients with mild and moderate hypertension in Navy General Hospital were enrolled in the study.The patients took regular exercise(6 min walking activity and treadmill test),Echocardiogram was performed 24 h after 6 min walking activity and treadmill test.The cardiac function related parameters were obtained through M-mode,2DE,pulse Doppler and DTI detection to compare the effect of 6 min walking activity and treadmill test on cardiac function.Results The results showed that in the male hypertensive patients,EF and E/E' after treadmill test were superior to those after 6 min walking activity (EF:(59.33±4.46)% vs.(56.05±4.57)%;E/E':(4.12±1.66)vs.(4.95±1.79)),the differences were statistically significant(P=0.02,0.01),while among the female hypertensive patients,there were no significant differences in cardiac function(P>0.05).Conclusion Appropriate activity can improve the cardiac function in male hypertensive patients.EF and E/E' after the treadmill test performed better than those after the 6 min walking activity,while its influence on female hypertensive patients was not significant.
