ABSTRACT
Objective:To establish the clot waveform analysis (CWA) reference intervals of prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fbg) and thrombin time (TT) parameters CT, |Min1|, |Min2|, |Max2| and observe the changes in patients with coagulation factors deficiency.Methods:One hundered and twenty-five cases of apparent healthy person were enrolled to establish the CWA reference intervals of four coagulation parameters and 25 cases with coagulation factors were used to study the changes of CWA patients.Results:The CWA reference intervals of PT |Min1| (dT/dt), |Min2| (d 2T/dt 2), |Max2| (d 2T/dt 2) are3.14±1.22, 0.56±0.22 and 0.50±0.18; The CWA reference intervals of APTT |Min1| (dT/dt), |Min2| (d 2T/dt 2), |Max2| (d 2T/dt 2) are 4.75±1.71, 0.78±0.29 and 0.65±0.28; The CWA reference intervals of Fbg CT(s), |Min1| (dT/dt), |Max2|(d 2T/dt 2) are 7.01±1.96, 1.22±0.51 and 0.15±0.11; The CWA reference intervals of TT |Min1| (dT/dt), |Min2| (d 2T/dt 2), |Max2| (d 2T/dt 2) are 0.95±0.32, 0.14±0.05 and 0.07±0.03.These parameters of CWA in factor Ⅴ deficient patients were significantly reduced, the activity of coagulation factor Ⅶ was 0.42, |Min2| and |Max2| were significantly lower than that of normal people. The paramenters of CWA in factor Ⅶ deficient patients were significantly reduce. Conclusion:The CWA reference intervals of four CWA parameters helps judgment of coagulation factor deficiency.
ABSTRACT
Objective: To determine loureirin A and B in different brands of home made resina draconis,providing basis for new quality control method.Methods: A high pressure liquid chromatography(HPLC) method has been developed. UV detector wavelength was set at 270 nm.The mobile phase was acetonitrile acetic acid solution (40∶60).The flow rate was 1.0 ml/min and the column was at room temperature.Results: A good linear correlation was found in the range of 4 to 24 ?g/ml of loureirin A.The regression equation obtained was Y =855.8+803 7.1 X ( r =0.999 9); A good linear correlation was found in the range of 20 to 120 ?g/ml of loureirin B.The regression equation obtained was Y =219.3+808 1.8 X ( r =0.999 9).Conclusion: The quantities of loureirin B in all brands are lower than the limit of quality standard.The quantities of loureirin A are higher than that of loureirin B in the same sample.
