OBJECTIVE: To evaluate the effects of Chinese herbal medicine for warming kidney on proliferation of normal human mammary epithelial cells in primary culture. METHODS: The normal human mammary epithelial cells were dissociated by digestion with collagenase type I. The morphological identification of normal human mammary epithelial cells in primary culture was determined under inverted phase contrast microscope and transmission electron microscope. The estradiol and progesterone were added to culture medium to induce the proliferation of normal human mammary epithelial cells in primary culture, and the different doses of Chinese herbal medicine for warming kidney and tamoxifen were also added into the culture medium. The MTT assay was used to evaluate the proliferation of normal human mammary epithelial cells in primary culture under the different conditions of interventions. RESULTS: The normal human mammary epithelial cells in primary culture presented typically morphological features of normal human mammary epithelial cells in vitro. The proliferation of normal human mammary epithelial cells in primary culture was significantly improved by intervention of estradiol and progesterone both with concentration of 1x10(-5) g/L. The high-dose Chinese herbal medicine for warming kidney could obviously promote the proliferation of normal human mammary epithelial cells in primary culture, while the proliferation was obviously inhibited by low-dose Chinese herbal medicine for warming kidney. The tamoxifen exerted no effects on the proliferation of normal human mammary epithelial cells in primary culture. CONCLUSION: The estradiol and progesterone can enhance the ability of proliferation of normal human mammary epithelial cells in primary culture. The regulating effect of Chinese herbal medicine for warming kidney on proliferation of normal human mammary epithelial cells in primary culture is dose-dependent.

OBJECTIVE: To investigate the effects of Astragalus injection (AI) on basal-like breast cancer cell line MDA-MB-468 and murine bone marrow stromal stem cells (mMSCs). METHODS: MDA-MB-468 cells and primary cultured mMSCs were treated by different concentrations of AI, and with untreated MDA-MB-468 cells as blank control. The morphology of cells was observed by phase-contrast inverted microscope and transmission electron microscopy. Cytotoxic effects of AI on MDA-MB-468 cells and mMSCs were evaluated by cell counting kit-8 (CCK-8) assay. Cell cycle and apoptosis of MDA-MB-468 cells induced by AI were measured by flow cytometry. Lactate dehydrogenase (LDH) activity in supernatants was measured by enzymatic colorimetric method. The expressions of epidermal growth factor receptor (EGFR) and p53 protein in MDA-MB-468 cells were evaluated by streptavidin-biotin-peroxidase complex method. RESULTS: A time-dependent cytotoxic effect of 1 g/ml AI was observed in MDA-MB-468 cells. 1 g/ml AI also had cytotoxic effect on mMSCs, but its effect was not better than cisplatin. 0.1 g/ml AI could promote the proliferation of mMSCs. Different concentrations of AI could all induce the apoptosis of MDA-MB-468 cells. There was no significant difference in LDH activity in the supernatants between blank control group and AI-treated and cisplatin-treated groups. AI could down-regulate the expressions of EGFR and p53 protein. CONCLUSION: The effects of AI on MDA-MB-468 cells and mMSCs are related to the concentration of AI, and its mechanism of inhibiting the proliferation of MDA-MB-468 cells may be due to down-regulation of the expressions of EGFR and p53 protein.

As the main medicinal powder for drawing out pus and removing necrotic tissue in external therapies of traditional Chinese surgery, Sheng Powder has made great contributions to the treatment of inflammatory wounds and has the unique bactericidal and decay-discharging function that can not be replaced by antibiotics. However, Sheng Powder has toxicity because it contains mercury. So far, there is no clinical research on the standards of dose and usage of Sheng Powder and there is a lack of objective and quantitative criteria for operating standards and monitoring of toxicity and side effects. Therefore, the authors choose Jiuyi Powder, one of the most commonly used Sheng Powder, to evaluate the safety of its external use, and form a standardization program for clinical implementation.

OBJECTIVETo observe the changes of the blood and urine mercury (Hg) levels and liver & kidney functions of rabbits after administration of Jiuyi Dan (calcined gypsum-Sheng Dan 9: 1) for 1 month and the recovery of rabbits after the drug withdrawal.

METHODThe rabbits were randomly divided into 2 groups: the calcined gypsum group and the Jiuyi Dan group. After 36 mg of calcined gypsum and 40 mg of Jiuyi Dan were used on the surface of wound (5 cm x 5 cm) on one side of rabbit back for 4 h, the surfaces of wound were washed by saline. The bloods were taken from the rabbit hearts before and after the drug administration for 14 and 28 days, and after the drug withdrawal for 7, 40, 71, and 92 days for determining Hg level in blood, and liver & kidney function indicators (ALT, AST, CREAT and BUN). The Hg level in urine collected from bladders was examined while rabbits were dissected after the drug withdrawal for 1, 40, 71, and 92 days.

RESULTThe Hg level in blood was significantly increased (P < 0.01) after the rabbits were administrated with drugs for 14 and 28 days and after the drug treatment was stopped for 7 and 40 days. The Hg level in urine was significantly enhanced after the drug withdrawal for 1, 40, 71 days. However, the liver & kidney indicators were not influenced.

CONCLUSIONThe Hg level in rabbit blood and urine was significantly increased after the consecutive administration of double-dose Jiuyi Dan for 1 month. However, the blood Hg level and urine Hg level recover after the drug withdrawal for 71 days and 3 months, respectively. The liver & kidney indicators do not significantly change with the dose.
