Objective To understand the effects of 17?-estradiol on MCF-7 cell proliferation and the regulation of estrogen receptor-related recepto(rERR?).Methods MCF-7 cells were treated with 17?-E2 at the doses of 10-12,10-11,10-10,10-9,10-8,10-7 and 10-6 mol/L for 24 h.Dimethyl sulfoxide were used as the solvent control.MTT method was used to determine inhibitory rate of MCF-7 proliferation,and the cells were treated with 17?-E2 at the doses of 10-10,10-9,10-8 and 10-7 mol/L for 24 h.RT-PCR method was used to detect the expression level of ERR?.Results Cell proliferation were promoted by exposure to 17?-E2 at the doses of 10-12,10-11,10-10,10-9,10-8,10-7 and 10-6 mol/L,the proliferation rate were 112.09%,122.09%,123.42%,120.46%,124.60% and 109.23% respectively,however,cell growth was inhibited at 10-6 mol/L of 17?-E2.The expression of ERR? in MCF-7 cells was upregulated at the doses of 10-10,10-9,10-8 and 10-7 mol/L when cells were treated with 17?-E2 for 24 h.Conclusion In certain dosage range,cell proliferation and expression of ERR? can be promoted by 17?-E2,which suggests that ERR? should play an important role in the process of MCF-7 cells growth.

Objective To study the effects of prenatal exposure to low level lead on the physical and neuro-behavioral development of mice and the interaction between lead and zinc. Methods Kunming pregnant mice were provided with drinking water containing lead, zinc and lead-zinc jointly and respectively. The body weight of maternal mice, offspring's survival rate and body weight were observed. Neuro-behavioral development of offspring was assessed by observation of offspring's behavior performance. The levels of dopamine (DA), 5-hydroxytryptamine (5-HT) and malonaldehyde (MDA) in offspring's brains were measured. Results At the doses of lead and zinc which did not effect the increase of maternal body weight during pregnancy, the lead exposure group showed low survival rate, growth retardation and delay of physiological development and neonatal reflexes in the offspring, the levels of DA and MDA in offspring's brains increased compared with the control group. Offspring's low survival rate and growth retardation couldn't be antagonized by zinc, but equal mole as lead of zinc could inhibit the harmful effects on neuro-reflex development. Zinc could also inhibit the increase of DA and MDA levels in offspring's brains induced by lead . However joint exposure to lead and half dosage as much as lead of zinc could deteriorate the effects on delay of physical, neuro-behavioral development and accelerate the DA and 5-HT decompose compared with that in the lead exposure group. Conclusion The harmful effects on offspring's growth and neuro-behavioral development could be induced by prenatal exposure to low level of lead. The types of joint-effect of lead and zinc were different according to the concentration of zinc, which indicated that the zinc-lead interaction was very complicated and it should be very prudent to antagonize lead toxicity using zinc.
