Aim To analyze the antibiotic activity and mechanism of a polypyridyl ruthenium complex. Meth-ods The antibacterial activity of [ ( Phen ) 2 Ru ( dp-pz) ] ( PF6 ) 2 was determined by MIC and MBC value. Based on a fluorescent activity of this complex, the flu-orescent emission spectra was used to analyze the com-bination of complex to DNA. Then the competition combination was analyzed between complex and Gold View to DNA. Lastly, gel electrophoresis of DNA was applied to detect the combination situation between complex and DNA. Results This kind of polypyridyl ruthenium complex showed a significant antibacterial activity with a minimum antibacterial conentration of 0. 2~0. 4 g · L-1 . That was caused by the combina-tion and distortion of DNA due to the activity of this complex. Conclusion The antibacterial activity and the mechanism of antibacterial activity about [ ( Phen) 2 Ru( dppz) ] ( PF6 ) 2 are confirmed in this re-search, which provides a good foundation for the devel-opment of such class of compound.

OBJECTIVE:To investigate the effects of uterine arterial embolization combined with Methotrexate and Lactate ethacri-dine on related indexes of mid-pregnant patients with placenta previa abortion. METHODS:The data of 100 mid-pregnant patients with placenta previa who required inducing labor was retrospectively analyzed and divided into observation group(50 cases)and control group(50 cases)by different treatment. Control group received uterine arterial embolization before inducing labor,then received Lac-tate ethacridine injection 100 mg,amniotic injection+Mifepristone tablet 75 mg,and aborted after 2 d. Observation group received uterine arterial embolization after uterine arterial perfusionon both sides,then received Methotrexate for injection 50 mg/side after uter-ine arterial embolization catheter entering uterine artery,Lactate ethacridine injection(the same usage and dosage as control group)+Mifepristone tablet(the same usage and dosage as control group)was given after 12 h. Total parturition,intrapartum hemorrhage,hos-pitalization time,menstruation recovery time,cesarean section,hysterectomy,retained placenta and clearing palace in 2 groups were observed,and postoperative complications were recorded. RESULTS:Intrapartum hemorrhage,hospitalization time,cesarean section rate and hysterectomy rate in observation group were significantly lower than control group,with statistical significance(P<0.05), while there were no significant differences in total parturition,menstruation recovery time,retained placenta rate and clearing palace rate in 2 groups(P>0.05). There was no significant difference in the incidence of postoperative complications in 2 groups(P>0.05). CONCLUSIONS:Uterine arterial embolization combined with Methotrexate and Lactate ethacridine can effectively reduce the hemor-rhage of mid-pregnant patients with placenta previa abortion,shorten hospitalization time,and decrease cesarean section and hysterec-tomy rate.
