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.

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.

Objective:To investigate whether VLA-5 and VLA-6 are involved in facilitating en-dothelium-oriented transmigration of hematopoietic stem/progenitor cells. Methods:Purified hu-man CD34+ cells were subject to ex vivo transmigration assay and blocking experiments throughtranswell filter inserts coated with human umbilical vein endothelial cells (HUVECs). Four-colorfluorescence-activated cell sorting (FACS) analysis was applied to detect the expression profilesof adhesion molecules and chemokine receptor CXCR-4 on CD34bright cells. Results:Stromal cell-derived factor (SDF)-1-induced transmigrations of both mobilized peripheral blood (mPB)-(56.6±20. 1)% and bone marrow (BM)- (15. 6±1. 8)% derived CD34+ cells were significantlyfacilitated through HUVECs-coated transwell filter insters compared with noncoated ones, whichwere efficiently blocked by preincubation of CD34+ cells with neutralizing antibodies to VLA-5,or VLA-6, or both of them; meanwhile the proportions of migrating CD34+ cells through bothHUVECs-coated and noncoated transwell filter inserts in BM were significantly lower than thosein mPB; the different percentages of migrating CD34+ cells between in mPB and BM were corre-lated with their variable expressions of VLA-5 and VLA-6, but not for VLA-4 or chemokine re-ceptor CXCR-4. Conclusion:Facilitating HS/PCs transmigrations through HUVECs are involvedin both VLA-5 and VLA-6.

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.

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.

Objective To investigate the effect of immediately lymphatic reconstruction (LR) after heterotopic small bowel transplantation on pharmacokinetics (absorption and transportation) of FK506. Methods Male Brown-Norway (BN) and Lewis (LEW) rats were divided to two groups. Group A: BN→LEW+LR+FK506 ( n =12); Group B: BN→LEW+FK506 ( n =12). FK506 at a dose of 5?mg/kg per day was taken through stoma. At 1, 4, 7 and 14 postoperative day (POD), venous blood 0.5?ml was obtained on the 1.2 , 2 and 3?h after administration of FK506. Whole blood concentration of FK506 was analyzed by microparticle enzyme immunoassay and a kit of monoclone antibody. Results At the every phase of early period after transplantation (1, 4, 7 POD), the levels of FK506 in plasma were significantly higher in group A than in group B ( P

To elucidate the effect of p27 KIP1 on cell cycle and proliferation of gastric carcinoma cells, we transfected the full e length cDNA of p27 KIP1 into human SGC7910 gastric cancer cells by the method of lipofectin transfection. Expression of p27 KIP1 at protein or mRNA level was analyzed by Western blotting, and RNA dot blotting, respectively. Effect of p27 KIP1 on cell growth was observed by trpan blue exclusion assay and anchorage independent growth in soft agar. Flow cytometry was applied to assess the effect of p27 KIP1 on cell cycle. The results showed that the expression of p27 KIP1 at protein or mRNA level increased evidently in SGC7901 cells transfected with p27 KIP1 . The cell growth was reduced by 42% 48h post induction with zinc as determined by cell viability assay. The rate of anchorage independent growth in soft agar decreased significantly. p27 KIP1 over expression caused cell arrest at G 1 by 36%(from 33 68% to 69 29%, P
