OBJECTIVE:To establish the HPLC method for determination of tanshinone Ⅱ A in compound Jinpu tablets METHODS:HPLC was performed on Shim-pack CLC-ODS(4 6mm?250mm,5?m) with methanol-water(15∶5) as mobile phase Flow rate was 1 5ml/min and detecting wavelength was 270nm Tanshinone Ⅱ A in compound Jinpu tablets was extracted by reflux method RESULTS:The calibration curve was linear in the concentration range of 0 01 333～0 10 667?g/ml(r=0 9 998,n=5) CONCLUSION:This method is simple,accurate,repeatable and effective for quality control of compound Jinpu tablets

Objective To explore the therapeutic effects of early mechanical ventilation and bedside h emafiltration in acute severe pancreatitis with acute lung injury Metho ds17 patients of acute severe pancreatitis with acute lung injury were ventilated (V T 8 ml/kg,PEEP 5～10 cm H 2 O) within 24 hrs after diagn osed Meanwhile bedside hemafiltration was performed six hours per day for 5 da ys The oxygenation and hemodynamics,function of heart,liver and kidney were m onitored ResultsCompared with control group,PaO 2 and P aO 2 /FiO 2 were increased markedly (P

AIM: To establish the method for determining tetrahydropalmatine、rhynchophylline and isorhynchophylline in AnshenYangxue Oral Liquid(Ramulus uncariae cum uncis, stephania kwangsiansis,Radix polygoni multiflori praeparata cum succo glycinus sotae,Caulis Polygoni multiflori and Pine needle). METHODS: Tetrahydropalmatine、rhynchophylline and isorhynchophylline were determined by HPLC.Chromatographic condition was composed of Kromasil C_18 column,a mixture of methanol and water(55∶45) as mobile phase with 0.01 mol/L triehthylamine,adjusted with acetic acid to pH of 7.5,UV detection wavelength of rhynchophylline and isorhynchophylline was set at 254 nm,UV detection wavelength of tetrahydropalmatine was set at 281 nm. RESULTS: The averagere recoveries of tetrahydropalmatine、rhynchophylline and isorhynchophylline were 98.47%、99.04%and 98.75% respectively;RSD were 0.95%、2.6%and 1.6%,respectively. CONCLUSION: This method is simple,sensitive,accurate,and can be used for determining tetrahydropalmatine、rhynchophylline and isorhynchophylline in Anshen Yangxue Oral Liquid.
