目的探讨血清肌酸激酶(CK)水平与输卵管妊娠病理类型的关系。方法2007年10月至2008年11月在长沙市第八医院就诊的输卵管妊娠患者,采用NAC激活,IFCC法,测定20例破裂型输卵管妊娠患者和26例未破裂型输卵管妊娠患者的血清CK水平。结果破裂型输卵管妊娠血清CK水平为(139.36±33.68)U/L,高于未破裂型输卵管妊娠(108.07±19.02)U/L,差异有统计学意义(P<0.01)。输卵管间质部妊娠血清CK水平(187.80±8.96)U/L高于峡部妊娠(148.37±12.64)U/L,又高于输卵管壶腹部妊娠(108.77±21.75)U/L,两两比较差异有统计学意义(P<0.05〉。以CK活性120U/L作为界值,预测输卵管妊娠破裂的灵敏度为80.0%,特异度为76.9%,阳性预测值72.7%,阴性预测值83.3%。结论测定血清肌酸激酶可用于破裂型和未破裂型输卵管妊娠的鉴别诊断,对预测输卵管妊娠破裂及选择合适的治疗方式有临床价值。
Objective To investigate the relationship between serum creatine kinase (CK) and tubal pregnancy pathology. Methods From October 2007 to November 2008, patients with tubal pregnancy treated at the 8th Hospital of Changsha City were enrolled in this study. Serum CK levels were measured in 20 patients with ruptured tubal pregnancy and 26 patients with unruptured tubal pregnancy by NCC activation and IFCC method . Results The serum level of CK in the ruptured tubal pregnancy was (139.36 ± 33.68) U / L, which was significantly higher than that of the unruptured tubal pregnancy (108.07 ± 19.02) U / L (P <0.01). Tubal interstitial pregnancy serum CK level (187.80 ± 8.96) U / L higher than isthmus (148.37 ± 12.64) U / L, and higher than tubal ampulla pregnancy (108.77 ± 21.75) U / L, any difference between (P <0.05) .The sensitivity and specificity of predicting tubal pregnancy rupture were 80.0%, 76.9%, 72.7% and 83.3%, respectively.Conclusion Serum Creatine kinase can be used for the differential diagnosis of ruptured and unruptured tubal pregnancy, which has clinical value in predicting the rupture of tubal pregnancy and selecting the appropriate treatment.
