Chinese Journal of Information on Traditional Chinese Medicine 2008;0(S1):-
Objective To evaluate the effect of integrated traditional Chinese and western medicine on endothelial function in patients with hypertension. Methods Thirty patients were randomly divided into two groups-the treated group and the control group. The patients in the treated group were treated by integrated traditional Chinese and western medicine, and the patients in the control treated by felodipine sustained release tablets (Plendil). The base line of brachial angiobore and the change of vascular diameter at response to nitroglycerin and reactive hyperemia were detected by using ultrasonography. Results After the treatment with integrated traditional Chinese and western medicine, the inner diameter were significant improved (P 0.05). Conclusion Integrated traditional Chinese and western medicine can improve endothelial function in patients with hypertension. Ultrasonography is a simple and effective method to evaluate the brachial arterial endothelial function.

The effects of protein kinase C (PKC) inhibitors 1- (5-isoquinolinylsulfonyl) - 2-methylpoperazine (H-7) and quercetin on endotheliai-polymorphoneuclear (EC-PMN) adhesion induced by tumor necrosis factor (TNF) and platelet activating factor (PAF) were studied in cultured bovine pulmonary artery endothelial monolayers in vitro. TNF (100 U/ml) and PAF (1.0 ?mol/L) stimulated EC dependent PMN-EC adhesion. Both H-7 and quercetin dose-dependently inhibited TNF and PAF induced PMN-EC adhesion. The IC50 of H-7 was 22.22, 5.25 umol/L, and that of quercetin was 18.30, 4.83 ?mol/L respectively. WEB-2086, a specific PAF receptor antagonist, dose-dependently inhibited PAF induced PMN-EC adhesion, but had no effect on TNF induced adhesion. These results suggest that PKC play an important role in EC activation by TNF or PAF, and TNF induced PMN-EC adhesion by independent on endogenetic PAF.

AIM: To observe the difference of actions among three traditional compl ex prescriptions with the same composition but the different dosage, including X iaochengqi Decoction, Houpudahuang Decoction and Houpusanwu Decoction, so as to provide evidence for their different clinical applications. METHODS: A series of experiments were performed, including carbon p rop ellance in small intestine, black stool excretion, cough induced by ammonia liqu or and phenol red secretion from trachea. RESULTS: Three prescriptions all enhanced carbon propellance in sma ll intestine at the high dosage, while at the low dosage only Houpusanwu Decoct ion showed the significant effect. They all shortened the latency of black stool a nd increased their total amounts in 6 hours at the high dosage, while at the low dosage Xiaochengqi Decoction and Houpudahuang Decoction had the significant p urgative action. Houpudahuang Decoction remarkably prolonged cough latency, dec reased cough times and enhanced phenol red secretion from trachea, while other t wo prescriptions had no obvious effects. CONCLUSION: Such results showed that Xiaochengqi Decoction had the better purgative action, while Houpusanwu Decoction regulated Qi strongerly, a nd Houpudanghuang Decoction showed the marked actions of relieving cough and re solving phlegm.

Objective To explore the proper proportion of effective fractions in Shengmaisan(saponins of Radix ginseng,saponins of Radix ophiopogonis,Lignans of Fructus schisandrae)in different anoxia models.Methods Acute cerebral hypoxia was induced by sodium nitrite and decapitation in mice,and the orthogonal design was used in these two models to find the proper proportion of three effective fractions.The gasping time of the mice,which were decapitated was observed to compare the anti-anoxia effects of XZF with other clinical drugs,and cerebral ischemic reperfusion injury model of mice was also used to study the effect of XZF on related biochemical index.Results XZF(the proportion of saponins of Radix ginseng,saponins of Radix ophiopogonis,Lignans of Fructus schisandrae as 7 ∶ 2 ∶ 6)significantly prolonged the gasping time,and decreased brain nitrogen monoxidum(NO)content after reperfusion of the mice at dosages of 50 mg/kg and 150mg/kg.Meanwhile,XZF also reduced malondialdehyde(MDA)content and increased superoxide dismutase(SOD)activity at the higher dosage.Conclusion XZF obtained by experimental screening exerts a significant protective effect on cerebral ischemia injury in mice,which provide some pharmacological evidence for further development of new modern Chinese drug composed with effective fractions for cerebral vascular diseases.

TSH1, a novel transcription factor in rice containing conserved AP2/EREBP domain, was screened from the EST database. The specific interaction of TSH1 and DNA elements was detected by two kinds of traditional methods, electronic mobility assay and yeast one-hybrid assay, which suggested that THS1 specifically binds to GCC element in vitro and in vivo. Furthermore, It was confirmed by atom force microscopy (AFM) that TSH1 binds to GCC element (core sequence GCCGCC) not DRE element (core sequence GCCGAC), and the single molecular force between TSH1 and GCC element was quantitatively measured. The molecular force of TSH1 with GCC element is (83.9 ?2.2) pN. This interaction can be observably blocked by the dissociate TSH1 protein in the solution. These above results proved that TSH1 recognizes and binds to GCC with specifically interaction, which also demonstrate the high sensitivity of the AFM measurements for the single base substitution of the GCC core sequence greatly reduced the binding affinity. Comparing these methods for identification the binding of transcription factor with its DNA element, it was considered that AFM is expected to be a sensitive and reliable method that offers valuable information for the characterization of transcription factors.
