ATM(Adobe Type Manager)Adobe字库管理系统 由美国公司开发的字库栅格化管理软件,它能够将Type 1轮廓字库在计算机中展开成点阵型数据,同时用于终端显示和打印机输出。另外,ATM还提供了用户自己制作字模的工具,可以进行Type 1对应的文字和新字体的追加和开发。由于计算机输出的文字数据已经是点阵型的,因而文字输出用的打印机即使不是PostScript对应型,不带字库也能够打印出PS字。但是,与带有字库的打印机相比,印字速度较慢。 展开更多

OBJECTIVE: To assess the effects of using Chinese herbs in assisted reproductive technology. METHODS: Four hundred and thirty-three subjects aged less than 42 years with infertility due to Fallo- pian tube or male-related factors who were willing to undertake in vitro fertilization and embryo trans- plantation were randomly allocated to a Chinese herb intervention group (n=216) or a conventional treatment control group (n=217). All subjects re- ceived one of four routine ultra-ovulation-promot- ing therapies at the Reproductive Center in the Third Hospital Affiliated to Beijing University ac- cording to their physician's assessments. The sub- jects in the intervention group received various Chi- nese herbs depending on their conventional treat- ment. Endometrial thickness, number of acquired eggs, and rates of normal fertility, high-quality em- bryos, biochemical and clinical pregnancy of sub- jects were assessed in both groups.RESULTS: The high-quality embryo rate of 51.9%, biochemical pregnancy rate of 51.0%, clinical preg- nancy rate of 44.2% and endometrial thickness of (10.84± 1.75) mm in the intervention group were all significantly higher than those in the control group [48.7%, 38.9%, 34.8%, and (10.52±1.50) mm, respec- tively; P〈O.05]. The normal fertility rate of 58.5% in the Chinese herb group was also significantly supe- rior to the 54.7% achieved in the control group (P〈 0.01). There were no statistically significant differ- ences (P〉0.05) in the average number of acquired eggs within a single cycle, incidence of excessive stimulation of ovary, rates of embryo transplanta- tion or early abortion and birth of living babies be- tween the two groups. CONCLUSION: Our findings indicate that Chinese herbs increase endometrial thickness, improve the quality of fertility and embryo, and promote embry- onic nidation, thus enhancing the success rate of in vitro fertilization/intracytoplasmic sperm injec- tion-embryo transplantation cycle. Using Chinese herbs improves the outcomes and safety of assist- ed reproductive technologies. 展开更多
