ABSTRACT
Objective To optimize ethonal extraction technology for no sugar runfei granules.Methods Ethanol was used as a solvent to extract the ethanol dissolvable ingredients in 9 kinds of medicinal materials.The formula L9 (34 ) table was used to examine the effects of 4 factors and 3 levels.The weighted sum of baicalin content and the dried extract quantity was used as quantitative index.Results The maximize optimize condition for extraction of ethanol dissolvable ingredients was as follows:9 kinds of medicinal materials, add of 10-fold 70% ethanol solution, soaked for 45 min, and extracted by heating reflux for 3 times,1.5 h each time.Conclusion The method can maximize extraction of ethanol dissolvable effective ingredents in 9 kinds of medicinal materials and can be used as ethonal extraction technologgary of no sugar runfei granules.
ABSTRACT
Objective To discuss the factors that maybe related to the analysis of results of percutaneous balloon pulmonary valvuloplasty (PBPV) and the changes of cardiac morphology after PBPV. Methods Multiple linear regression was used to study peak gradient, balloon-anulus ratio (BAR), pulmonary orifice area and time of inflation before and after PBPV. One hundred and thirty-eight patients (age between 6 months and 28 years old, mean 8.34?0.81). T test was used to study the diameter and thickness of the right ventricle (RV), and Rv 1 of ECG before and during the follow-up. F test was used to determine peak gradient before and after PBPV and during the follow-up. Results There was a notable reduction in the peak to peak gradient from 13.55?0.69 kPa to 4.51?0.41 kPa (P
