BACKGROUND: In traditional Chinese medicine, both deficiency as primary and excess as secondary and deficiency of qi and blood stasis are common symptoms in dialectical logy of atherosclerosis (AS). Therefore, qi-benefiting drugs are the main component of qi-benefiting and blood-activating intervention. However, the best dose relationship between qi-benefiting and blood-activating drugs needs to be further studied.OBJECTIVE: To observe the effect of qi-benefiting and blood-activating intervention on the expression of aortic vascular cell adhesion molecule-1mRNA (VCAM-1mRNA) in AS models and analyze dose-effect relationship between astragalus and sanchi.DESIGN: Randomized control animal study.SETTING: Shanxi Medical University.MATERIALS: The experiment was carried out in the Shanxi Medical University in April 2005. A total of 60 healthy male Wistar rats were selected in this study. The main reagents were quercetin (Shaanxi Huike Plant Co., Ltd., batch number:20041112), saponins of panax notoginseng (PNS, Kunming Yagechen Pharmaceutical Co., Ltd., batch number:20050118) and ligustrazine (Yuxin Guoji Longyuan Pharmaceutical Co., Ltd., batch number: 20041204).METHODS: Model establishment: Wistar rats were administrated AS feeds (including 10% yolk powder, 5% lard, 0.5% bile salt and 85% basic feed) for 3 months. Grouping and administration: At threedays after suitability feeding, 8 rats were randomly selected, regarded as the normal control group and given general feeds, and other 52 rats were fed with AS feeds. Three months later, 4 rats were randomly selected for the measurements of lipid and aortic tissue. And then, the models were established successfully. In addition, 48 rats were randomly divided into 6 groups. ① Astragalus treatment group: Rats were perfused with 0.1 g/(kg·d) quercetin. ② Sanchi treatment group: Rats were perfused with 0.1 g/(kg·d)PNS. ③ 2∶1 of astragalus/sanchi treatment group: Rats were perfused with 0.1 g/(kg·d) quercetin and 0.05 g/(kg·d) PNS.④ 3∶1 of astragalus/sanchi treatment group: Rats were perfused with 0.15 g/(kg·d) quercetin and 0.05 g/(kg·d) PNS. ⑤Ligustrazine treatment group: Rats were perfused with 0.2 g/(kg ·d) ligustrazine (Yuxin Guoji Longyuan Pharmaceutical Co., Ltd.). ⑥ Normal control group: Rats were fed with general feeds. ⑦ Model group: Rats were fed with general feeds after successful model estalishement. Thirty days after administration, relative expression of VCAM-1mRNA inaorta was measured with reverse transcription polymerase chain reaction (RT-PCR) technique; moreover, 2 mL venous blood was collected from tail to measure the levels of serum total cholesterol (TC), triacylglycerol (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C).MAIN OUTCOME MEASURES: ① Relative expression of VCAM-1mRNA in aorta; ② level of lipid.RESULTS: Among 60 male Wistar rats, three rats in the treatment group died because of perfusion and two rats in the model group died due to accident; therefore, a total of 51 rats were involved in the final analysis. ① High-lipid diet could promote the formation of AS models. Level of lipid was higher in the model group than that in the normal control group (P＜ 0.05), and leves of serum TC, TG and LDL-C were lower in the interventions group than those in the model group (P ＜0.05). ② Expression of VCAM-1mRNA was not found in the normal control group. Expression of VCAM-1mRNA was lower in the intervention groups than that in the model group. Expression of VCAM-1mRNA (0.42±0.02) was the lowest in 3∶1 of astragalus/sanchi treatment group, and there were significant differences as compared with other intervention groups (P ＜ 0.05).CONCLUSION: Astragalus and sanchi, a main component of qi-benefiting and blood-activating herbs, can down-regulate the level of lipid and resist AS; meanwhile, the combination of them is superior to the single application; in addition, with the increasing deal of qi-benefiting drugs, the function against AS is strengthened.

Objective To compare the effect of active compression-decompression cardiopulmonary resuscitation(ACD-CPR) with standard- cardiopulmonary resuscitation(S-CPR) on ventricular function in a canine ventricular fibrillation model. Methods Ventricular fibrillation was induced in anesthetized and instrumented canine. Twenty-four dogs were randomly assigned to either ACD-CPR group or S-CPR group.After 4 minutes of untreated VF,two-dimension echocardiography was used to evaluate the left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV) and left ventricular ejection fraction (LVEF) of every canine of the two groups when they were undergoing cardiopulmonary resuscitation. Results During ventricular fibrillation, both ACD-CPR group and S-CPR group showed decreased LVEDV compared with pre-ventricular fibrillation, but not statistically significant( P ＞0.05).LVEDV was increased in ACD-CPR group compared with S-CPR group, but not statistically significant (P＞ 0. 05). Both ACD-CPR group and S-CPR group showed significantly increased LVESV compared with pre-ventricular fibrillation,of which the difference was statistically significant ( P ＜0. 001). Both ACD-CPRgroup and S-CPR group showed significantly decreased LVEF compared with pre-ventricular fibrillation,of which the difference was statistically significant (P ＜0. 001). LVEF was increased in ACD-CPR group compared with S-CPR group,of which the difference was statistically significant ( P = 0.019). Conclusions Compared with S-CPR,ACD-CPR resulted in higher LVEF.

AIM To study pathogenesis of Alzheimers disease and screen ?- secretase and ?- secretase inhibiting drug, PS-1(M 146L)and APP 751 gene double stably transfected CHO cell lines have been established. METHODS A? cDNA encoding human PS-1 was obtained by polymerase chain reaction from a human placental library. Mutant PS-1 (M 146L) cDNA was also generated by polymerase chain reaction from wild type PS-1 cDNA. Wild type and mutant PS1 were subcloned into CMV-based mammalian expression vectors PCI-neo,then recombined plasmid were co-transfected into APP expressing CHO cells at 1∶10 ratio using LipofectAmine. Stable expressing cell lines were screened and selected by using selection media. RESULTS Several CHO cell lines stably transfected with wide type or mutant PS-1 (M 146L) as well as APP 751 genes were established. Overexpression of PS-1 in CHO cell accumulated full length 45 kDa PS-1 protein. A? released to conditioned media were not changed in wild type PS-1 transfected APP expression CHO cells. A? 1～42 level in conditioned media of M 146L mutant PS-1 stably transfected of APP expression CHO cells were elevated about 1.6 fold. CONCLUSION Expression of M 146L mutant PS-1 in stably transfected APP expression CHO cells increased a secretion of A? 1～42. The PS-1 and APP double stably transfected CHO cell lines we generated can be used for either ?-or ?-secretase inhibitor study and related drug screening.
