Objective To synthesize a new reagent, 1-(6-bromo-2-benzothiazolyl)-3-(5-bromo-8-quinolyl)-triazene (BBTBQT) and apply to the determination of cobalt. Methods The reagent had been synthesized by diazotization and coupling reaction. After purification and characterization, BBTBQT was tested for its color reaction conditions with cobalt in the presence of cetylpyridinium bromide (CPB). Results In the presence of borax buffer solution at pH value of 9.0, the reagent reacted with cobalt to form a blue stable complex with a molar ratio of 2∶1; the complex had a maximum absorption at 640 nm. The apparent molar absorptivity of the complex is 1.55 ?105 L/(mol?cm). Beer’s law was obeyed in the range of 0-0.28 mg/L for cobalt. The method had been applied to determine cobalt in drainage sediment and vitamin B12 injection solution with a mean relative error of 1.9%-5.8% and a standard relative deviation of 1.7%-3.8%. Conclusion The present method is selective, sensitive, accurate, convenient and suitable for determination of trace cobalt in the samples.

Objective: To identify the chemical components in traditional Chinese herbal medicine Ginseng by high performance liquid chromatography diode array detector (HPLC-DAD) and High performance liquid chromatography-time of flight mass spectrometry (HPLC-TOF/MS). Methods: An Agilent Zorbax XDB-C18 column (250 mm X 4.6 mm, 5 μm) was used for isolation and identification of chemical components in Ginseng with a mobile phase of acetonitrile and water in gradient elution. A gradient program was used as follows: 1-35 min, 19% A; 35-55 min, 19%-29% A; 55-70 min, 29% A; 70-110 min, 29%-40% A; 110-150 min, 95% A. The flow rate was set at 1.0 ml/min, the injection volume was 20 μl, the column temperature was set at 20°C. The time-of-flight mass spectrometer was equipped with an EIS ion source. Scanning mass range was between m/z 100-1 350. Results: Thirty-nine chemical compounds in Ginseng were identified unequivocally. Conclusion: Chromatographic demonstration of 39 chemical compounds of Ginseng in one run is achieved by HPLC-TOF/MS, which provides a foundation for further study on the metabolism and action mechanism of traditional Chinese herbal medicine.

Objective To study the effects of the antiarrhythmic drugs of propafenone, amiodarone and dilthiazem on c-type Kv1. 4 channels in Xenopus laevis oocytes with two-electrode voltage-clamp technique. Methods Defolliculated oocytes ( stage Ⅴ - Ⅵ) had transcribed cRNAs of ferret Kv1. 4△N channels injected. The oocytes were continuously perfused with control solution or propafenone, amiodarone and dilthiazem under monitoring of software of Clampfit v 9. 0. Results All of the three drugs blocked ferret Kv1. 4△N channel in voltage-, frequency- and concentration-dependent manners. The values of IC50 (50%inhibiting concentration ) of propafenone, amiodarone and dilthiazem were ( 103.4± 2. 2 ) μ mol/L,(501.22 +5.9) μmol/L and (353.62 +9.9) μmol/L, respectively. The currents under the actions of propafenone , amiodarone and dilthiazem were decreased to 41%, 32% and 21% of control group, respectively. Propafenone (100μ mol/L), Amiodarone (500μmol/L), dilthiazem (350μmol/L) inhibited currents to (54. 6 + 1.9 ) %, ( 46. 3 + 3.5 ) %, ( 52. 8 ± 2. 8 ) % of control group in voltage-dependent blockage. Conclusions The results suggested that all the three drugs blocked the kv1. 4△N channel in the open state. The three drugs block the kv1. 4△N channel maybe had the similiar effects in some respects, but each had its unique characteristics.

The effects of the antiarrhythmic drug propafenone at c-type kv1.4 channels in Xenopus laevis oocytes were studied with the two-electrode voltage-clamp techinique. Defolliculated oocytes (stage V-VI) were injected with transcribed cRNAs of ferret Kv1.4 delta N channels. During recording, oocytes were continuously perfused with control solution or propafenone. Propafenone decreased the currents during voltage steps. The block was voltage-, use-, and concentration- dependent manners. The block was increased with positive going potentials. The voltage dependence of block could be fitted with the sum of monoexponential and a linear function. Propafenone accelerated the inactivate of current during the voltage step. The concentration of half-maximal block (IC(50)) was 121 micrometer/L. With high, normal, and low extracellular potassium concentrations, the changes of IC(50) value had no significant statistical differences. The block of propafenone was PH- dependent in high-, normal- and low- extracellular potassium concentrations. Acidification of the extracellular solution to PH 6.0 increased the IC50 values to 463 micrometer/L, alkalization to PH 8.0 reduced it to 58 micrometer/L. The results suggest that propafenone blocks the kv1.4 delta N channel in the open state and give some hints for an intracellular site of action.

OBJECTIVETo evaluate the effect of post-treatment PSA kinetics on the prognosis of prostate cancer (PCa).

METHODSWe retrospectively reviewed the clinical data of 114 cases of locally advanced PCa treated by maximal androgen blockade (MAB) combined with brachytherapy, and analyzed the association of the changes in PSA kinetics with the prognosis of the patients.

RESULTSThe median survival time of the patients was 81 (15 - 144) months, with 1-, 3- and 5-year survival rates of 91. 23%, 78.07% and 68.42% , respectively. Univariate analysis indicated that the baseline PSA level, PSA nadir, the time of PSA decreasing to nadir, PSA doubling time, and the extent of PSA declining were all predictive factors for the survival time of the PCa patients. Multivariate analysis demonstrated that PSA nadir, the time of PSA decreasing to nadir, and the extent of PSA declining were three independent prognostic factors, which prolonged the long-term survival of the patients by 1.7, 3.2 and 6.8 times, respectively.

CONCLUSIONFor locally advanced PCa treated by MAB combined with brachytherapy, PSA nadir <1 micro g/L, the time to nadir <3 months, and the extent of PSA declining >96% are independent prognostic factors.
