Objective To explore the impacts of Danhong injection on physiological and biochemical indicators in malnourished mice at physiological low doses, evaluate its safety, and test the practical value of safety re-evaluation of Traditional Chinese Medicinal ( TCM) injections. Methods A total of 32 ICR mice during growth period were selected to set up corn deficient nutrition mice model. Mice were assigned into the normal control group (given 0. 9% saline), Danhong injection at low, medium and high dosages (0. 2, 0. 4 and 0. 6 mL) groups (n=8 in each group);Mice were administered with respective medications intraperitoneally for 7 consecutive days. Blood samples were taken and mice were executed on the 8th day. All 9 kinds of organ or tissue were obtained completely, to measure related physiological and serum biochemical parameters. The safety of Danhong injection was evaluated by using Benefit and Damage Index - General Score ( BDI-GS ) system. Results The Danhong injection showed only slight damages on major organs or tissues, the BDI values were all above 0. 85, and the GS values were all above 9. 0;BDI values for Danhong injection at different dosages were all above 1. 0 for spleen and pancreas, showing better replenishing and healthy effects, and the differences were of statistical significance compared with the normal control group (P<0. 05 or P<0. 01). Meanwhile, it exerted obviously hypoglycemic effect. Conclusion Danhong injection is of rather low risk under physiological dosages, and therefore is safe to use. The mal-nutrition model combined with the BDI-GS system may be developed as a novel approach for safety re-evaluation of TCM injection in clinic.

OBJECTIVETo investigate the effects of arsenic trioxide (As(2)O(3)) on the apoptosis and p-glycoprotein (P-gp) expression of multidrug-resistant human leukemia cells.
METHODSHuman multidrug-resistant leukemia cell line K562/ADM overexpressing the MDR1 gene, was used as the target cells. The cell proliferating activity was assessed using the MTT colorimetric assay. Cytomorphology was investigated under light, confocal and electron microscopes. DNA fragmentation was examined using agarose gel electrophoresis, while p-gp expression, cell cycle status and sub-G1 cells were determined using flow cytometry.
RESULTSZero point five to 20 micromol/L As(2)O(3) inhibited the proliferation of K562/ADM cells, and K562/ADM cells were more sensitive to As(2)O(3) than the parental K562 cells. As(2)O(3)-induced apoptosis of K562/ADM cells was determined by the observance of typical morphological changes and the appearance of DNA ladder and sub-G1 cell populations. As(2)O(3) significantly inhibited the P-gp expression of K562/ADM cells, and synergistically enhanced the sensitivity of the drug-resistant cells to adriamycin.
CONCLUSIONSAs(2)O(3) induces growth-inhibition and apoptosis, down-regulates P-gp expression and exerts a synergistic effect in combination with adriamycin in multidrug-resistant leukemia cells.

Objective To investigate the prevalence of physical state of HPV-l6 DNA in cervical cancer and cervical precancerous carcinoma. Methods Multiplex PCR was adopted to detect the physical state of HPV in samples from 252 patients with cervical carcinoma, including 48 samples of cervical cancer, 204 cervical intraepithelial neoplasia (CIN ) (125 CIN I, 46 CIN II and 33 CIN III) and 20 normal samples from the subjects with hysteromyoma undergoing hysterectomy, respectively. Results Among 48 patients with cervical cancer, 31 (65.6%) were infected with HPV-16. Eighteen among 31 (58.1%) HPV-16 infected patients with cervical cancer were found to have integrated infection of HPV-16. The positive rates of HPV-16 infection in the patients with CIN I, CIN II and CIN III were 19.2%, 34.8%and 42.4%, and the integrated infection rates of HPV-16 were 16.7%, 18.8%and 35.7%, respectively. Compared with patients with different grades of CIN, the integrated rate of HPV-16 infection in those with cervical cancer was significantly elevated. Conclusion Among the patients with HPV-16 infection, the integrated state of HPV-16 is positively correlated with the severity of cervical lesions. Combined HPV typing test and detection of integrated viral state contribute to predicting the prognosis of patients with cervical precancerous lesions and increasing the accuracy of screening cervical cancer on the basis of HPV DNA detection.
