CONCLUSION:ADR reporting and monitoring should be strengthened in hospital.Making full use of hospital ADR infor mation can facilitate rational drug use and improve clinical rational drug use level.

Objective To assess the clinical value of microguidewire looping technique in superselective catheterization of the acute angled artery. Methods Manipulating the microguide wire into a U shaped loop and simultaneus withdrawal of the microguidewire and microcatheter was performed when the tip of the microguidewire simultaneous got into the target artery and following by slowly and simultaneously withdrawing the microguidewire and microcatheter until the tip of the microguidewire entering into the target artery for a certain length and finally pushed the microcatheter into the target artery slowly. Results Eighteen out of 21 patients with acute angled target artery were successfully catheterized through this approach with technical success rate of 86%, without any complications. Conclusions Microguidewire looping technique is a feasible method for superselective catheterization of the acute angled artery when the routine approach failed.

The relationship between immune vasculitis and atherosclerosis was studied. The experimental model of weanling rabbits for immune vasculitis was reproduced by intravenous injection of 10% bovine serum albumin. There were 6 groups: group A, 25 weanling rabbits with immune vasculitis subject to coronary arteriography; group B, 10 normal mature rabbits subject to coronary arteriography; group C, 10 weanling rabbits subject to coronary arteriography; group D, 8 weanling rabbits with vasculitis and cholesterol diet; group E, 8 weanling rabbits receiving single cholesterol diet; group F: 8 weanling rabbits receiving basic diet. Four weeks later, coronary arteriography was performed in groups A, B and C. The rabbits in groups D, E and F were sacrificed for the study of pathological changes in the coronary artery after 12 weeks. The results showed that the dilatation of coronary artery occurred in 6 rabbits of group A, but in groups B and C, no dilatation of coronary artery appeared. In comparison with group E, more severe atherosclerosis occurred in group D, showing the thickened plaque, fibrous sclerosis and atherosclerotic lesion. Percentage of plaques covering aortic intima, incidence of atherosclerosis of small coronary arteries and degree of stenosis of coronary arteries were significantly higher in group D than in group E (P < 0.01). No atherosclerosis changes were found in group F. It was concluded that in the acute phase, the serum immune vasculitis can induce the dilatation of coronary artery of some weanling rabbits, and aggravate the formation of atherosclerosis in rabbits fed with cholesterol diet. Immune vasculitis is a new risk factor of atherosclerosis and ischemic heart disease.

BACKGROUND: Moxonidine is the second-generation high-selective central antihypertensive drug, while clonidine is the first-generation antihypertensive drug that is used in clinic with many side effects.OBJECTIVE: To compare the characteristics between moxonidine and clonidine in renal-hypertensive rats.DESIGN: Randomized controlled animal experiment.SETTING: Department of Pharmacology, Medical College, Nantong University.MATERIALS: The experiment was conducted in Medical College, Nantong University between September and December 2004. Totally 110 SD rats aged 60 days with the body mass of (180±30) g were used in the study.METHODS: Left renal artery stenosis in SD rats was established by inserting silver clip with the inner diameter of 0.2 mm or 0.25 mm, while the right renal artery was not received, so as to establish two-kidney one-clip(2K-1C) renal hypertensive models. ①Changes of blood pressure and heart rate in awake rats with renal hypertension were determined with arteria caudilis indirect manometric method, oral administration once or consecutively. The experiment of depressurization with once oral administration:The rats were randomly assigned into 5 groups with 10 rats in each group:1 mg/kg, 3 mg/kg, 10 mg/kg moxonidine hydrochloride groups, 1 mg/kg clonidine hydrochloride group were considered as positive control group,while saline group as negative control group. On the basis of the effect of moxonidine hydrochloride on blood pressure, blood pressure was measured at 1, 4, 24, 48, 72 hours after moxonidine administration, and compared with that before administration or the effect of saline. The experiment of depressurization with consecutively oral administration once a day. The grouping was the same to above-mentioned. Successive administration was for 7 days, once a day. The blood pressure and heart rate were determined at 1 hour before and after administration, and observed for 3 days after drug withdrawal. Recommended dose of moxonidine hydrochloride for human was about 0.4 mg/kg, while the oral dose for rats were around 0.04 mg/kg based on the animals' surface area. ②Changes of blood pressure and heart rate in anaesthesia rats with renal hypertension with a catheter on the carotid artery directly: 0.2 mg/kg drug liquor was given with gastric perfusion. The rats were randomly divided into 5 groups with 10 ones in each group: 0.13,0.4, 1.3 mg/kg moxonidine hydrochloride groups, 0.13 mg/kg clonidine hydrochloride group and saline control group. Mean arterial pressure was determined before and after administration at different time.MAIN OUTCOME MEASURES: Changes of blood pressure and heart rate in conscious and anesthetized renal-hypertensive rats before and after being administrated orally once or consecutively.RESULTS: All the rats were involved in the result analysis, without drop out during the trial. ①Moxonidine showed a dose-dependent effect on depressurization and descent of heart rate after once large dose oral administration in conscious renal-hypertensive rats. The 10-fold higher doses of moxonidine caused the same effects of clonidine. The decreasing of heart rate was little and short after consecutively small dose of oral administration of moxonidine, and which was similar to clonidine in percentage of depressurization. ②In anesthetized renal-hypertensive rats, moxonidine showed a dose-dependent effect on depressurization after once oral administration. There was no significant difference between moxonidine and clonidine in percentage of depressurization after 3 to 10-fold higher dose administration (P ＞ 0.05).CONCLUSION: The once higher dose oral administration of moxonidine has dose-dependent effect on depressurization for renal-hypertensive awake rats. Anesthesia. The effect of 10-fold dosage of moxonidine is equal to that of clonidine. The effect of 3-10-fold dosage of moxonidine is equal to that of clonidine in anesthesia renal-hypertensive rats. The small dose oral administration continuously of both moxonidine and clonidine with the same volume has the same depressurization effect in renal-hypertensive rats.

ObjectiveTo investigate the effect of p27 KIP1 transfection on cell cycle and apoptosis of hepatocellular carcinoma cells(HCC). MethodsWe used an inducible expression system pMD neo, which allowed controlled expression of protein upon addition of zinc as an external inducer. p27 KIP1 cDNA was transfected into human HCC 9204 cell line. Expression of p27 KIP1 was analyzed and cell growth was observed. ResultsExpression of p27 KIP1 in protein and mRNA increased significantly in HCC 9204 cell line transfected with p27 KIP1 . The cell growth reduced by 35%, p27 KIP1 over expression caused cell growth arrest at G 1 by 35% ( P =0 000). Apoptotic cell index significantly increased ( P =0 000).Conclusionp27 KIP1 may cause cell cycle arrest in G 1 phase and subsequently lead to apoptosis.
