Fisher判别分析在预测异位妊娠中的价值探讨

Objective To discuss the value of Fisher discriminant analysis of serum progesterone and the growing rate of β-human chorionic gonadotropin in the prediction of early ectopic pregnancy. Methods 66 patients with ectopic pregnancy (11 cases were successfully treated expectantly and 55 cases were treated surgically including 40 cases of rupture of fallopian tube and 15 cases of tubal abortion) and 55 patients with intrauterine pregnancy and 50 patients with threatened abortion were chosen. Serum progesterone,β-HCG,48 hβ-HCG and the 48 h growing rate of β-HCG in each group were measured and a Fisher discriminant analysis was used. Results The serum progester-one was (30.27± 18.20) nmol/L in ectopic pregnancy group,( 108.44±23.27 ) nmol/L in intrauterine pregnancy group and (91.68±34.90) nmol/L in threatened abortion group. The first β-HCG was ( 3767.63 ± 3530.38 ) U/L in ectopie pregnancy group,(29 028.65 ± 10 874.01 )U/L in intrauterine pregnancy group and (13 457.47±16 367.65)U/L in threatened abortion group. The second β-HCG was (4349.24±3536.22)U/L in ectopic pregnancygroup,(56 139.46 ± 23 296.87 ) U/L in intrauterine pregnancy group and (23 270.63 ± 23 811.68 ) U/L in threat-ened abortion group. The growing rate of β-HCG ( β-HCG/the first serum β-HCG) was 1.29 ± 0.28 in ectopic preg-nancy group,1.93 ± 0.36 in intrauterine pregnancy group and 1.97±0.28 in threatened abortion group. There was significant difference in serum progesterone,the first β-HCG and the second β-HCG as well as the growing rate of β-HCG among the groups(P<0.05 or <0.01). Fisher discriminant analysis of combing progesterone and the growing rate of β-HCG were connected with diagnosis of ectopic pregnancy,however,the only one serum β-HCG was not con-nected with diagnosis of ectopic pregnancy. 98.5% of ectopic pregnancy,65.6% of intrauterine pregnancy and 64.0% of threatened abortion were correctly classified in the Fisher discfiminant analysis,with overall correct rate of 77.8%. Conclusion Fisher discriminant analysis of combing progesterone and the growing rate of β-HCG can bet-ter predict the early ectopic pregnancy.

Fisher判别分析在预测异位妊娠中的价值探讨

目的 探讨根据血清孕酮和β-HCG比率建立的Fisher辨别函数在预测异位妊娠中的价值.方法 选择2005年1月至2007年7月在我院住院最后确诊为异位妊娠的患者66例(保守治疗成功11例;手术治疗55例,其中输卵管破裂40例,输卵管流产15例);正常宫内妊娠组(最终诊断)55例;宫内孕先兆流产组(最终保胎治疗成功)50例.测定3组患者的血清孕酮、β-HCG、间隔48 hβ-HCG、β-HCG 48 h比率,应用判别分析,筛选判别因子,建立Fisher判别函数,回顾性地进行考核,评价判别分析的诊断效率.结果 3组孕酮比较,异住妊娠组(30.27±18.20)nmol/L,正常宫内孕组(108.44±23.27)nmol/L,先兆流产组(91.68±34.90)nmol/L;3组第1次血清β-HCG的比较,异位妊娠组(3767.63±3530.38)U/L,正常宫内孕组(29 028.65±10 874.01)U/L,先兆流产组(13 457.47±16 367.65)U/L;3组间隔48 h后第2次血清β-HCG的比较,异位妊娠组(4349.24±3536.22)U/L,正常宫内孕组(56 139.46±23 296.87)U/L,先兆流产组(23 270.63±23 811.68)U/L;血清β-HCG比率(血清β-HCG/第1次血清β-HCG)的比较,异位妊娠组1.29±0.28,正常宫内孕组1.93±0.36,先兆流产组1.97±0.28.3组的孕酮、β-HCG、间隔48 hβ-HCG、β-HCG比率差异均有统计学意义(P<0.05或P<0.01).应用判别分析,筛选出血清孕酮、β-HCG比率均与异位妊娠的诊断有关,单次血清β-HCG值与异位妊娠的诊断无关.根据孕酮值和β-HCG比率建立的Fisher判别函数,对判别分析的结果用交互验证进行回顾性考核,异位妊娠组的判别正确率是98.5%,正常宫内妊娠组的判别正确率是65.5%,先兆流产组的判别正确率是64.0%,总正确率77.8%.结论 根据血清孕酮和β-HCG比率建立的Fisher判别函数在早期异位妊娠的诊断中有较好的预测价值.
