Coronary artery disease is one of the most common and important health problems in the world. Early diagnosis of this disease is very important to treat before severe myocardial damage occurred. Myocardial perfusion scintigraphy (MPS) and computed tomography coronary angiography (CTCA) which evaluates regional myocardial perfusion and coronary arteries, respectively, are reliable and non-invasive methods in terms of coronary artery disease. In this study we aimed to compare MPS and CTCA based on conventional coronary angiography (CCA). Totally 60 patients were included in the study. CCA and MPS were performed to 30 patients;CCA and CTCA were performed to the rest of the patients (30 patients). Lesions were classified as mild, moderate and severe in these imaging methods. MPS and CTCA were compared with CCA by using chi-square and Fisher’s exact test. MPS and CTCA’s p values were found for left anterior descending artery (LAD) p: 0, p: 0.271;for circumflex artery (Cx) p: 0.256, p: 0.08 and for right coronary artery (RCA) p: 0.033, p: 0.271, respectively. Furthermore MPS and CTCA’s sensitivity, specificity, accuracy, positive predictive value and negative predictive value were calculated 81% to 87%;70% to 49%;73% to 72%;54% to 72%;90% to 71%, respectively. CCA results were found more concordant with MPS for LAD and RCA lesions and more concordant with CTCA for Cx lesions. It was also found that positive predictive value of MPS and negative predictive value of CTCA were significantly higher than the others. As a result, MPS and CTCA were suggested as complementary techniques for the diagnosis of coronary artery disease, not as alternatives to each other.

1.引言激光器被认为是切割、钻孔、焊接等工业应用方面实用而经济的工具。激光切割的优点有(1)加工件与激光头间无机械接触。(2)对入射激光束聚焦的光学系统也可用作定位,所以精密切割得到简化。(3)切割性能不太受加工件的力学性能影响。激光切割时,激光与加工件间相互作用的机理十分复杂,并对加工性能和产品质量有巨大影响。许多人对激光的金属切割作了研究,然而对用激光裁剪织物材料没有作过

世界核心医学期刊文摘（妇产科学分册） 2005年第4期1卷 45-45页

作者： Agrawal R. Sharma S. bekir J. 刘亦恒

To determine the prevalence of polycystic ovaries (PCO) and polycystic ovarian syndrome (PCOS) in lesbian women compared with heterosexual women undergoing fertility treatment. A prospective observational study. The London Womens clinic and The Hallam Medical Center. Tertiary referral fertility setup. Six hundred eighteen women undergoing ovarian stimulation with or without IuI treatment between November 2001 and January 2003. Of these, 254 were selfidentified as lesbians and 364 were heterosexual women. Baseline pelvic ultrasound examination and blood tests conducted to measure biochemical parameters such as FSH, LH, E2, PRL, T, androstenedione (A), sex hormonebinding globulin (SHBG), and DHEAS were performed between day 2 and 3 of each womans menstrual cycle. Tubal patency tests were performed by hysterosalpingography or laparoscopy. Biochemical parameters. Eighty percent of lesbian women, compared with 32%of the heterosexual women, had PCO on pelvic ultrasound examination. Thirtyeight percent of lesbian women, compared with 14%of heterosexual women, had PCOS. There were no significant differences in the androgen concentrations between lesbian and heterosexual women with normal ovaries. However, lesbian women with PCO and PCOS had significantly higher androgen concentrations compared with heterosexual women with PCO and PCOS. Tubal disease was as common in lesbian women as in heterosexual women. There is a significantly higher prevalence of PCO and PCOS in lesbian compared with heterosexual women. Lesbian women with either PCO or PCOS had more pronounced hyperandrogenism than did heterosexual women with either PCO or PCOS.
