OBJECTIVE:To establish the HPLC fingerprints for Dangua yangmu cream. METHODS:HPLC was performed on the column of Kromasil C18 with mobile phase of acetonitrile-0.026% phosphoric(gradient elution)at flow rate of 0.8 ml/min,the detection wavelength was 270 nm,the column temperature was 25 ℃ and the injection volume was 20 μl. The chromatographic peak of aurantio-obtusin was used as reference peak to determine the 10 batches of Dangua yangmu cream,and Similarity Evalua-tion System for Chromatographic Fingerprint of TCM(version 2.0)was conducted to identify common peaks and evaluate similari-ty. RESULTS:There were totally 25 common peaks in the 10 batches of Dangua yangmu cream,and the similarity was not lower than 0.921. The validation results showed the fingerprints of 10 batches of Dangua yangmu cream had good consistency with the ref-erence fingerprints. COMCLUSIONS:The established method is specific and reliable,and can provide basis for the quality evalua-tion and control of Dangua yangmu cream.

Objective:To study the effects of Ophiocordyceps xuefengensis on proliferation of DC -CIK cells and the activity of killing HepG-2 cells by DC-CIK cells.Methods:Peripheral blood mononuclear cells were routinely isolated and induced into DC and CIK.DC and CIK co-cultured by 1∶5 for 7 days,then Ophiocordyceps xuefengensis were added into medicine group ,observed the mor-phology of the cells on the tenth day and counted the DC-CIK number of each group.DC-CIK cells acted as effector cells and the HepG-2 cells as target cells , cck-8 method for the detection of DC-CIK in the killing rate of HepG-2.Results: The Ophiocordyceps xuefengensis was able to proliferate the DC-CIK dramatically ,the optimal concentration was 0.1 mg/ml.Cultivation of Ophiocordyceps xuefengensis induced DC-CIK cells on HepG-2 cells killing effect was better than that of the routine method of DC-CIK cells; the effection of Ophiocordyceps xuefengensis killing HepG-2 cells was not obviously.Conclusion: Ophiocordyceps xuefengensis can enhance the anti-tumor activity of DC-CIK mainly by promoting the proliferation of it.
