BACKGROUND:Intrauterine device made of bare copper can release a great amount of oxides that are easy to cause bleeding and pain in women. Nano copper/low-density polyethylene intrauterine device can wel solve the above drawbacks, which is conducive to the maintenance of the reproductive health of women of childbearing age. OBJECTIVE:To explore the effect of nano copper/low-density polyethylene intrauterine device on post-implantation uterine bleeding and pain. METHODS:A total of 98 voluntary women asking for intrauterine device insertion were selected and randomized into control group (n=49) with 220C (TCu220C) T type copper intrauterine device and observation group (n=49) with nano copper/low-density polyethylene intrauterine device. Al the women were folowed up for 12 months, and incidence of adverse events, including uterine bleeding and pain, was observed and compared between the two groups. RESULTS AND CONCLUSION: During the folow-up, there were one case of uterine bleeding and two cases of pain in the observation group and the incidence of adverse events was 6%; in the control group, there were five cases of uterine bleeding and eight cases of pain, and the incidence of adverse events was 27%. There was a significant difference in the incidence of adverse events between the two groups (P< 0.05). These findings indicate that the nano copper/low-density polyethylene intrauterine device can effectively reduce the occurrence of uterine bleeding and pain after implantation.

The Glu and Asp levels in CSF may be regarded as indicator of DEACMP.

The self-designed experiments of extract preparations is practiced in pharmacy teach-ing. Students work in groups, first consulting literature material, selecting the prescription and devis-ing a plan. Then, if the plan has carried on the feasible proof, students begin to purchase raw materi-als, complete the extraction and separation of effective components, the preparation of molding and the analysis of experimental results and finally form their self-evaluation. This experiment can strengthen students' experiment skill and promote their comprehensive application ability of all the subjects in the pharmacy field. At the same time it can also play an important role in the improvement of the students' social practice ability and the cultivation of students' creative thinking.
