RESUMO

AIM To develop a UPLC-MS/MS method for the simultaneous content determination of adenosine,salidroside,chlorogenic acid,calycosin-7-O-β-D-glycoside,specnuezhenide,calycosin,formononetin,quercetin,apigenin and astragaloside Ⅳ in Zhenqi Fuzheng Capsules (Ligustri lucidi Fructus and Astragali Radix).METHODS The analysis of methanol extract of this drug was performed on a 40 ℃ thermostatic Inertsutain C18 column (75 mm × 3.0 mm,2 μm),with the mobile phase comprising of methanol-acetonitrile-4 mmol/L ammonium acetate flowing at 0.5 mL/min in a gradient elution manner.RESULTS Ten constituents showed good linear relationships within their own ranges (r≥0.996 0),whose average recoveries were 95.1%-104.3% with the RSDs of less than 4.20%.CONCLUSION This sensitive and specific method can be used for the rapid quality control of Zhenqi Fuzheng Capsules.

RESUMO

Objective To investigate the clinicopathological characteristics,immunophenotype and the differential diagnosis of ectopic hamartomatous thymoma (EHT).Methods Three cases with EHT were studyed for clinicopathological and immunohistochemical features, the available literature on this subject was reviewed as well.Results The tumors of 3 patients with EHT were located at left lower neck,right supraclavicular area,and left supraclavicular area respectively,and were underwent local resection.The well-defined nodular tumors were en-capsulated with gray-yellowish cut surface,with size of 2.5 cm ×1.9 cm,4.5 cm ×4.5 cm,and 3.0 cm ×2.5 cm,respectively.Microscopi-cally,the tumors were composed of spindle cells,epithelium,and adipose tissue with the predomination of spindle cell.A gradual transition from epithelial cells to spindle cells was frequently present.Immunohistochemically,both the spindle cell and epithelial components were dif-fusely and intensely positive for AE1 /AE3,CK7,CK19,and P63.Two patients with EHT were followed up for 18 and 27 months,both without any evidence of metastasis or recurrence.Conclusion EHT is an exceedingly rare benign tumor with distinctive location and histological fea-tures and should be differentiated from biphasic synovial sarcoma,malignant schwannoma with epithelial differentiation,mixed tumor,thymoli-poma,et al.The total focal excision is the first treatment of choice for EHT.
