ABSTRACT
Objective To compare the efficacy of endovascular interventional treatment and surgical clipping in posterior communicating artery aneurysm (PCoAA) patients with fetal-type posterior cerebral artery (fPCA).Methods The PCoAA patients with fPCA were enrolled.Their baseline clinical data were collected.The modified Rankin Scale (mRS) was used to assess the clinical outcomes at six months after procedure.The mRS score 0-2 was defined as good outcome.Results A total of 35 PCoAA patients with fPCA were enrolled into the study,23 were treated with interventional embolization therapy and 12 were treated with craniotomy clipping.There were no significant differences in age,gender,preoperative Fisher grade,Hunt-Hess grade,baseline GCS scores,and aneurysm typing between the 2 groups.The good outcome rate of the interventional embolization group at 6 months was higher than that of the surgical clipping group,but there was no significant difference (65.22％ vs.41.67％;P =0.282).Results The efficacy of PCoAA using interventional embolization therapy combined fPCA is almost the same as craniotomy clipping.
ABSTRACT
Objective To develop a HPLC fingerprints of Glycyrrhiza uralensis Fisch.in Inner Mongolia.Methods The RP-HPLC method was adopted on Phenomenex C18(4.6?250 mm,5 ?m)analytical column by gradient elution with acetonitrile and acetic acid buffer solution as mobile phase.The gradient wavelength data acquisition was employed.The analysis time was 60 minutes and the flow rate was 1 mL/min.Results The HPLC standard fingerprints chromatography of Glycyrrhiza uralensis Fisch.consists of 10 common characteristic peaks.The results of method validation accorded with the technical standard of fingerprints.Conclusion This method is stable,accurate,reliable,and can provide a scientific basis for the quality control of Glycyrrhiza uralensis Fisch..
