Abstract:
Objective:To study the effects of the iridoid aglycones from Patrinia scabra on mouse colon cancer cell line C26 in vitro and on transplanting-tumor of mouse colon cancer cell C26. Methods: The effects of the iridoid aglycones from Patrinia scabra(PS-I, BJ3401)on mouse colon cancer cell line C26 were studied by MTF experiment,the transplanting-tumor model of mouse colon cancer was established by hypodermic inoculating the mouse colon cancer cell lines C26 into the FI mice. Results: The iridoid aglycones PS -I and BJ3401 could significantly inhibit proliferation of C26 cell line in a doge-dependent manner,gross iridoid aglycones could sig- nificantly lessen the weight of the transplanting-tumor in mice.Conclusion :The iridoid aglycones from Patrinia scabra have anti-colon carcinoma activity.

Abstract:
Objective:To study the therapeutic effect of Weichi liniment on acute soft-tissue injury. Methods: Animal models of acute soft-tissue injury were made in 30 healthy white rabbits,and the animals were randomly divided into three groups(n=10 rabbits each):Weichi liniment,honghuayou and control group.The therapeutic effects were observed by methods of gross and histology.Re- sults:Weichi liniment bears better dispelling action of edema,analgesic action and dispelling stasis.The inflammation response of Weichi group to trauma in histology was significantly lighter compared with other 2 groups. Conclusion: Weichi liniment could inhibit traumatic aseptic inflammation and exert an effect of relieving swelling and dispersing blood stasis and might be an ideal external used drug in treating acute soft tissue injury.

Abstract:
Objective:To establish a new analytical method for the identification of steroid hormones. Methods: Convolution trans- form combined with information visualization techniques were employed in the data mining of ultraviolet spectrum,resulting in the fin- gerprint spectrum of certain compounds.The similarity coefficient of fingerprint spectrum based on cosine algorithm was further used in the identification of 23 steroid hormones,ie.prednisolone,betamethasone,pregnendione,etc.,after the method was validated.Re- suits :The method showed acceptable precision and ruggedness.There were large differences between the similarity coefficients of differ- ent types of steroid hormones.The unsaturated bond contributed greatly to the differences between the similarity coefficients of same types of steroid hormones,while the side chain or its esterification had relatively small effect on the similarity coefficients. Conclusion: Convolution transform combined with information visualization techniques broadens the application of ultraviolet spectrum in the pharma- ceutical identification.
