Objective To compare the safety and effectiveness of three types of intrauterine device (IUD) inserted immediately after artificial abortion.Methods A randomized controlled clinical trial was performed in 4 family planning service stations in Pudong New Area from January to December 2012.Total 1 200 eligible women were randomly assigned to receive three types of IUD:MYCu,TCu380A or G-Cu200 (n =400 in each group) immediately after vacuum aspiration.All subjects were followed up for 12 months.The cumulative rates of termination of three IUD after 12 months were analyzed with WHO LTA 2.0 life table.Results Total 1 199 subjects were followed up for 12 months with a drop-out rate of 0.08％ (1/1 200).No any uterine perforation was found.During the 12 months the pregnancy rates with IUD in situ in MYCu,TCu380A and G-Cu200 groups were 0.26/100 women year,0 and 0.52/100 women year,respectively (x2 =1.951,P ≥ 0.2).The rates of expulsion in three groups were 0.26/100 women year,1.84/100 women year and 2.05/100 women year,respectively(x2 =5.539,P =0.066).The remove rates related to bleeding and paining in three groups were 1.26/100 women year,7.29/100 women year and 2.76/100 women year,respectively (x2 =21.625,P =0.001).The discontinuation rates related to IUD use in there groups were 3.25/100 women year,9.00/100 women year and 5.50/100 women year,respectively(x2 =12.191,P =0.004).The rates of Abnormal position in three groups were 1.51/100 women year,0 and 0.26/100 women year,respectively (x2 =8.649,P =0.014).Conclusion Three IUDs inserted immediately after vacuum aspiration are all effective.Among three IUDs,MYCu shows lower expulsion rate,lower discontinuation rate related to IUD use and higher continuous rate; but the abnormal position rate of MYCu is higher than other two types IUD.

As a vital component in an overall laboratory animal care and use program , development of a disaster plan plays a critical role for every research institution .Currently, most of domestic institutions would draw up an“emergency operation plan , EOP”, but ignoring a practicable “business continuity plan , BCP” in establishing a disaster plan.In this article, we will discusse about the definition of disaster , how to set up an EOP, and how to establish a thorough BCP , in order to show an integrated and professional disaster plan in laboratory animal care and use program .

The types of the voltage-dependent calcium channels (VDCCs) in human ejaculatory sperm and the effects of calcium channel blocker (CCB) on human sperm motility parameters in vitro were investigated. The human sperm motility parameters in vitro in response to the pharmacological agents nifedipine (NIF, inhibitor of L-type VDCC) and co-conotoxin (GVIA, inhibitor of N-type VDCC) were compared and analyzed statistically. The results showed that NIF (1, 5, 10 micromol/L) could not only significantly affect human sperm's shape but also spermatozoa motility after incubated at least 10 min in vitro (P<0.001). GVIA (0.1, 0.5 and 1 micromol/L) could just only significantly affect human sperm's progressive motility (a %+b %) after incubated for 20 min in vitro (P<0.01), but they both could not significantly affect spermic abnormality rate. It is suggested that L-type VDCC, non L-type VDCCs and isoform of L-type VDCC exist in the cell membrane of human sperm solely or together, and they participate in the spermic physiological processes especially the spermic motility.

BACKGROUND:Kalikrein 1 is an important component of the kalikrein-kinin system. Studies have shown that kalikrein can protect the cardiovascular system by promoting angiogenesis and inhibiting myocardial inflammation, but there is no report on its effect on inducing differentiation of stem cels. OBJECTIVE: To determine the transfection efficiency of kalikrein 1 adenoviral vector in rat bone mesenchymal stem cels. METHODS:Using adenovirus as a vector, the target gene kalikrein 1 was transfected into rat bone marrow mesenchymal stem cels. Fluorescence microscopy, MTT method and flow cytometry were used to investigate the effect of transfection and determine the optimal multiplicity of infection. RESULTS AND CONCLUSION:Adenovirus carrying kalikrein 1 was successfuly transfected into rat bone marrow mesenchymal stem cels. Results from flow cytometry showed that the transfection efficiency was associated with the multiplicity of infection. When the multiplicity of infection was 150, the transfection efficiency was 80.8%. MTT results showed that when the multiplicity of infection was 200, the cel growth was inhibited remarkably. These findings indicate that adenovirus-mediated kalikrein 1 can be successfuly transfected into rat bone marrow mesenchymal stem cels with the optimal multiplicity of infection=150.
