OBJECTIVE To synthesize[3H]labelled trantinterol and determine the mass balance in rats and the profile of trantinterol and its metabolites in excreta. METHODS [3H]Trantinterol was synthesised from the intermediate1-(4-amino-3-chloro-5-trifluoromethyl-phenyl)-2-bromo-ethanone through reduction by sodium borotritide and aminolysis by t-butylamine. Following an oral dose of[3H] trantinterol(45.5 MBq·kg-1)to bile duct cannulated(BDC)rats and normal rats. Bile,urine and faeces were collected individually before and after dosing at different times. Liquid scintillation counter(LSC) was used to detect total radioactivity recovery and HPLC/radio-detector for metabolite profiling in urine and bile. RESULTS The majority(73.6%)of the administered radioactivity was recovered in the first 24 h postdose with 48.3%in urine and 25.4%in faeces. It was cumulated to(84.7±6.8)%till 168 h. In BDC rats,29.3%of the dose was recovered in the bile 3 d post-dose. According to the peak area ratio determined by HPLC/radio-detector,only 4.7%and 9.5%of the radioactive dose were excreted as the parent drug in urine and bile,respectively,while the majority of the remaining radioactivity was excreted in the form of various metabolites. CONCLUSION Following oral administration in rats,trantinterol is completely absorbed,extensively metabolized and rapidly excreted mainly in urine as various metabolites.

Objective To develop a HPLC-MS/MS method for the determination of aconitine and study thein vitro metabolic stability of aconitine in dog tissue homogenates.Methods The chromatographic separation was performed on a C18 column.The mobile phase consisted of acetonitrile and water with 0.2％ formic acid and 5 mmol/L ammonium acetate.A triple quadrupole tandem mass spectrometer equipped with an electrospray ionization interface source was used for the quantitative determination in the positive selective reaction monitor mode.Aconitine was incubated with dog tissue homogenates and samples were withdrawn at different time points and precipitated by acetonitrile with internal standards citalopram.Results Aconitine showed good linear relationship over the range from 5 to 500 ng/ml.The recoveries of aconitine were between 85.73％ and 92.12％ at three QC concentration levels.The intra- and inter-day precisions were 5.32％ - 8.95％ and 5.45％ - 8.86％,respectively.After incubation,about 20％ of aconitine were cleared in the liver and small intestine,and t1/2 were 460.6 and 521.3 min,respectively.But none was metabolized in the stomach and kidney.Conclusion These results demonstrated that aconitine was mainly metabolized in the liver and small intestine at a slow rate.

In this study, the effects of apollon antisense oligodeoxynucleotide (ASODN) on the proliferation and apoptosis of human Lovo cells in vitro were investigated. Apollon ASODN was incubated with human colorectal Lovo cells for 48 h, the proliferation inhibition and the clone forming rates were detected by WST method and clone formation assay, respectively. The expression of apollon mRNA was analyzed by real time fluorescent quantitative reverse transcription polymerase chain reaction. The percentage of apoptotic cells and cell cycle distribution were determined by flow cytometry. The morphology of apoptotic cells was examined by fluorescence microscope. Lovo cells incubated with apollon ASODN combined with 5-fluorouracil (5-FU), cisplatin (DDP) or epirubicin (EPI) of different concentrations, cell proliferation inhibition rates were detected with WST method and IC50 was calculated. It was found that ASODN targeting apollon gene could all suppress the growth of Lovo cells and induce apoptosis of these cells significantly (P < 0.05). After Lovo cells treated with apollon ASODN for 48 hours, the expression of the apollon mRNA level was suppressed significantly. And a marked concentration-dependent decline of cell proliferation and clone forming, increasing of cell apoptosis levels were observed. The percentage of G0/G1 phage cells was abated and that of S phage cells was increased and the Lovo cells arrested at S phage of the cell cycle detected with flow cytometry. Many Lovo cells stained with Hoechst 33258 exhibited apoptotic morphology such as cell shrinkage, nuclear condensation and nuclear fragmentation. Cell proliferation inhibition was detected and their chemo-therapeutic effects of 5-FU, DDP and EPI on Lovo cells combined with apollon ASODN (0.08 micromol x L(-1)) were enhanced independently compared with single 5-FU, DDP and EPI groups, and the sensitivity enhanced about 2.58, 4.47, and 5.33 times respectively. It can be concluded that ASODN targeting apollon can suppress the expression of apollon mRNA, and inhibit the proliferation, induce apoptosis, arrest cell cycle at S phase of colorectal cancer Lovo cells in vitro and enhance the chemo-sensitivity to 5-FU, DDP and EPI.

ObjectiveTo investigate the long term effect of different antihypertensive agents on renal hemodynamics with ultrasound Doppler.Methods52 essential hypertensive patients were divided into three groups according to the antihypertensive agent they took: angiotensin-converting-enzyme inhibitor (ACEI), calcium channel blocker (CCB) and β-adrenoceptor blocker (βB). The blood pressures of right upper arms were measured with mercury column blood pressure gauge using Korotkoff method. Renal hemodynamics were examined with ultrasound Doppler before and after treatment with agents. ResultsSystolic blood pressure (SBP) and diastolic blood pressure (DBP) of all patients were decreased significantly. An significant correlation was found between the deceases of blood pressure and the betterment of renal homodynamic parameters in ACEI and CCB groups, but not in βB group. ConclusionTo a degree, the betterment of renal hemodynamics is correlation with the reduction of systemic blood pressure and mechanism of action of antihypertensive agents.
