RESUMEN
Objective To investigate the value of Pituitrin in neonatal cardiopulmonary resuscitation.Methods Seventy-three cases with neonatal cardiopulmonary arrest admitted in emergency department and NICU in our hospital were collected during 2007 to 2011.Newborns who did not respond to conventional neonatal resuscitation therapy were divided into two groups:epinephrine group 47 cases (control group) and Pituitrin combined with epinephrine group 26 cases (treatment group).Results There were no statistical difference (x2 =0.956,P ＞ 0.05) between treatment group and control group in the rates of initial resuscitation success (23.1％,6/26 vs 34.0％,16/47).Conclusion Pituitrin combined with epinephrine has similar efficacy with the use of epinephrine in neonatal cardiopulmonary resuscitation.
RESUMEN
Objective To establish a simultaneous method for determination of 5 constituents from Panax quinquefolium stem leaf 20(S)-protopanaxdiol saponins,Ginsenoside-Rb1,Rc,Rb2,Rb3 and Rd by RP-HPLC.MethodsPanax quinquefolium stem leaf 20(S)-protopanaxdiol saponins was provided by the Ji'an Yisheng Pharmaceutical Stock Co.Ltd..The Agilent ODS column(5 ?m,4.6 mm?250 mm)was used,and eluted with acetonitrile-0.2% phosphoric acid water in gradient mode.The UV detection wavelength was 203 nm,and the flow rate was 1.0 ml/min,with the temperature of column at 40 ℃.The accuracy,stability and repeability of this method was evaluated.The yield rate was measured.ResultsFive compounds were baseline separated,with good linearity.A standard curve was plotted.Our method was proved to have sound accuracy,stability and repeability.The yield rate was 98.39%,97.36%,98.02%,97.70% and 97.01% respectively for Ginsenoside-Rb1,Rc,Rb2,Rb3 and Rd.ConclusionOur method of determination is rapid and accurate,and can be used for controlling the quality of Panax quinquefolium 20(S)-protopanaxdiol saponins.
