Objective To compare the effectiveness of medicated γintrauterine device (IUD) and medicated genefix IUD inserted immediately after abortion. Methods A multicenter clinical trail was performed for the study from Mar. 2012 to Jan. 2013. Totally 840 women who volunteered to participate were randomly allocated to γ-group (medicated γ IUD) or genefix-group (medicated genefix IUD) immediately after abortion. While 464 abortion women who had not used IUD or steroids contraceptive methods were chosen as control group. The effectiveness of the IUD were followed up for 1 year. All women were required to record the number of vaginal bleeding days and blood volume of vaginal bleeding within 3 months after abortion. Results At the 12th month, the expulsion was the most common reason for termination. The expulsion rates of genefix-group and γ-group were 2.48/100 women years and 3.12/100 women years, respectively (P>0.05). For the expulsion reasons, IUD moving down could account for more than seventy percent. The removal rate for IUD usage of two IUD groups were almost equal (3.91/100 women years verus 4.35/100 women years), the differences were not statistically significant (P>0.05). At the 90th day after abortion, comparing with control group, the bleeding and (or) spotting days of genefix-group and γ-group extended by 3.9 and 2.6 days respectively, the differences had statistical significance between the three groups (P<0.05). Among the bleeding and (or) spotting days, spotting days prolonged significantly. At the 12th month, spotting days of genefix-group andγ-group were (9.2±5.9) days and (8.5±4.6) days respectively, more than (5.2 ± 4.0) days of control group. The differences had statistical significance between IUD with control group (P<0.05), and had not between the two kinds of IUD (P>0.05). Conclusion The insertion of medicated genefix IUD and medicated γ IUD immediately after abortion is safe, feasible, has slight side effects and could be effective contraception.

Objective To investigate stilbene glycosides(TSG) and PNS concomitantly on PC12 cell survival rate of Alzheimer's disease.Methods The nerve cells that were seeded on the two culture plates were cultured for 1 day after the removal of primary culture fluid.In addition to the blank group, the model group and drug compatibility group were added 5 μl Aβ25-35 perpore to induced PC12 cell damage.To established AD cell damage model after exposure to the circumstances for 24 hours.Uniform design and factorial design were used respectively.After 1 d, using MTT method in ELISA analyzer measured the OD value of each pore, and calculating the survival rate of cells.Results The uniform design results showed that the cell survival rate was significantly linear with TSG and PNS (P＜0.05).From the equation, The higher the dose, the higher the cell survival rate.In this experimental condition, TSG and PNS respectively 50 mg/L, 200 mmol/L achieved the highest cell survival rate.2×2 factorial design experiments showed that, compared with the model group, the cell survival rate of TSG-PNS group (74.46％ ± 2.06％ vs.65.42％ ± 1.42％) increased (P＜0.05), but there was no interaction between the two groups (P=0.053).This showed that the combination of the two drugs in this dose has a protective effect on AD damage.Conclusion The compatibility of total saponins of two stilbene glucoside and three seven combination has the synergistic effect of anti AD damage.
