On the basis of analyzing traditional Chinese medicine(TCM) pathogenesis character of early hypertension in Macao,to induce the main pathological mechanism of early hypertension is stagnation of phlegm and blood,excess of liver yang.Activiting qi,blood and regulating vessel are general principles of treatment.Dissipating phlegm and promoting blood circulation,repressing hyperactive liver yang and nourishing tendon interrupt early pathological change,moreover,it embodies the TCM theory of ‘early treatmrnt to prevent deterioration’.

[Objective] To evaluate the effect of Bushen Yixin Tablet (BYT) on blood pressure (BP) and hemorrheology in rats with hypertension. [Methods] Rat models of hypertension were established by constricting either of the bilateral renal arteries with one clip. Sixty rats were randomly allocated to high - dose BYT group (Group A), low - dose BYT group (Group B), nitrendipine (Group C) and normal saline group (Group D) . Ten rats served as mimic group (Group E) . BP of tail artery was examined in various groups and after a 4 - week treatment, whole blood viscosity and indexes of erythrocyte aggregation (EA) and erythrocyte deformation (ED) were detected. [Results] BP was increased, high- , middle - and low - shear whole blood viscosity and EA index were elevated and ED index was decreased in model rats as compared with those of the normal. After treatment, BP and whole blood viscosity were reduced and ED index was increased in Group A, Group B and Group C, and EA index in Group A was lowered as compared with those in Group D (P

Objective To study the variation of serum IL-1?, Hs-CRP, the monocytes infilitrating into the intima, the expression of HSP-70 in diet-induced hyperlipidemic and chronic Cpn-infected mice and the intervention of berberine. Methods Mice were inoculated intranasally with Cpn three times, every 2 weeks over a 6-week period and fed with high cholesterol diet. C57BL/6J mice were divided randomly into 6 groups:Ber1 group, Ber2 group, azithromycin group, atorvastain group, model group, and normal group. Ber1 group were given berberine at the beginning of Cpn infecting, while Ber2 group, azithromycin group and atorvastain group were given the drug after the 3rd Cpn infecting. The serum index, HE dye of the aortas and immune-histochemistry index were observed. Results The level of serum IL-1?, Hs-CRP, the monocytes infilitrating counting and the expression of HSP-70 in model group were increased. All of the index in Ber group, azithromycin group and atorvastain group declined to some extent. Conclusions Berberine has effect of decreasing inflammatory indexes of diet-induced hyperlipidemic and chronic Cpn-infected mice.

Objective To study the variation of the level of lipids, OX-LDL and vascular intimal injury in diet-induced hyperlipidemic and chronic Cpn-infected mice and the interventional functions of berberine. Methods C57BL/6J mice were divided randomly into 6 groups: Berl group, Ber2 group, azithromycin group, atorvastain group, cholesterol + Cpn group, and normal group. Mice were inoculated intranasally with Cpn for three times, every 2 weeks over a 6-week period and feeding with high cholesterol diet. Berl group was administrated with berberine at the beginning of CPn infecting, while ber2 group, azithromycin group and atorvastain group were administrated with the drug after the 3rd CPn infecting. The serum index, HE dye of the aortas and electron microscopic examination were observed. Results Lipids disorder, increased level of OX-LDL and vascular intimal injury were found. The level ofTC, LDL, TG OX-LDL in Bet group, azithromycin group, and atorvastain group declined in different extent. Conclusion Berberine has effects of regulating lipids disorder, OX-LDL and protecting vascular intima of diet-induced hyperlipidemic and chronic Cpn-infected mice.

The level of serum hs-CRP, WBC and homocysteinemia were observed. Results The level of serum Hs-CRP, WBC and homocysteinemia declined in different extent after treated by SanHuang pill, the treated group showed a better result than the control group. Conclusions Heat-clearing and detoxicating remedy can reduce the level of serum Hs-CRP and homocysteine.

To investigate the effects of Bushen Yixin Tablet (BYT) on plasma lipid peroxide (LPO) and sexual hormone in renal hypertension rats. Goldblatt's renal hypertension rat models were established. All rats were allocated to six groups: BYT groups (with high, moderate and low dosage of BYT respectively), captopril group, normal saline (NS) group and mimic-operation group. The treatment course lasted 4 weeks. Blood pressure was lowered in BYT groups (P

Objective:To explore the e ects of clinical treatment and protection on endothelial function of early essential hypertension patients treated with YiNianJiangYa(YNJY) soup in southern Guangdong area.Methods:79 early essential hypertension cases with traditional Chinese medicine(TCM) syndrome of phlegm stasis blocking collaterals,excess of liver yang were randomly divided into treatment and control groups,treated with YNJY soup and TianMaGouTeng(TMGT) soup respectively for two courses of treatment.Di erences of clinical treatment e ect,blood pressure and pulse pressure after treatment,as well as plasma endothelin-1(ET-1) and von Willebrand factor(vWF) between the two groups were measured.Results:The clinical total e ective rate of treatment group was higher than that of control group(P 0.05).Conclusion:YNJY soup can signi cantly improve clinical treatment e ect of the early essential hypertension patients,has good e ect of decreasing blood pressure and no obvious side e ects.It has many e ects that reduces PP and the levels of plasma ET-1,vWF,may be related to protection of endothelial function,thereby improve the artery exibility.

AimTo investigate the immune effects of the genetic engineering vaccine against swine cysticercosis with the animal mode of kunming mouse. Method78 kunming mice were randomly divided into three groups: 1 )injection one times with the vaccine, 2)injection twice with the vaccine at intervals of ten days, 3)non-vaccination group. All the mice were infected with the vial hatched oncopheres by the tag vein at 20 days after the first vaccination,and were killed and dissected to look for swine cysticerci 63 days later. In order to know the immune response of the vaccine and the stateof parasites in the rats,the antigens and antibodies of swine cysticerci were detected by immune methods. ResultsThe vaccine was safety to all the vaccinated rats. The antibodies against swine cysticerci began to appear positive in some of the immunized mice at 7 days postvaccination,and they were all positive at 21 days. 65 cysticerci were found in the mice of the nonvaccination group,which lodged mainly in the chests. 2 and lcysticerci were respectively found in two rats of the first group and in one rat of the second group, their protective rates of cysticerci were 96.9％ and 98. 4％,respectively. ConclusionKunming mouse as the animal model of swine cysticercosis was stable and reliable,and the genetic engineering vaccine against swine cysticercosis was safety and efficiency.

[Objective] To observe the preventive effect of Huanglian Jiedu Decoction (HJD), a prescription with the actions of clearing heat and removing toxicity, on rabbits atherosclerosis (AS) induced by Chlamydia pneumoniae (CP) infection. [Methods] Fifty two New Zealand rabbits were fed with forage containing 2. 5g/kg cholesterol and were infected with CP via nasopharynx for three times during 6 weeks. At the end of the sixth week, forty four rabbits with serum CP-IgG positive were randomized into 4 groups: group A treated with HJD 2g?kg-1 ?d-1 by gastric gavage, group B with HJD 1g?kg-1?d-1, group C with azithromycin 20 mg?kg-1?d-1 and model group D with normal saline for 6 weeks. Group E was set up in 8 rabbits fed with fatty forage and served as the control. Serum levels of high-sensitive C reactive protein (hs-CRP) and CP-IgG were detected before infection, after infection and after treatment. At the end of the 18th week, the rabbits were executed and the pathological features of aortic tissue were observed under microscope. Meanwhile, the expression of CP-DNA and tumor necrosis factor ?(TNF-?) in the aortic tissue was detected with polymerase chain reaction (PCR) and immunohistochemical method respectively. [Results] At the end of the experiment, atherosclerotic changes were obvious in groups D and E, particularly in group D. Compared with group D, the atherosclerotic damage was much relieved, and AS indexes such as maximum intimal thickness (MIT), atherosclerotic damage percentage and plaque area index were much improved in groups A and C (P
