Abstract To study the expression of serum plasminogen activator inhibitor-1 (PAI-1), soluble human leukocyte antigen-G (sHLA-G), macrophage mobility inhibitor (MMIF) of women with endometriosis, and to study their significance for clinical diagnosis in endometriosis (Ems). Methods: 68 women with Ems were included in study group from January 2019 to June 2020. In addition, 65 healthy women were selected in control group during the same period. The levels of serum PAI-1, SHla-G, and MMIF of the women in the two groups were analyzed. The serum PAI-1, SHla-g and MMIF levels for diagnosing Ems was analyzed by receiver operating characteristic (ROC) curve. Results: The serum levels of PAI-1 (193.56±61.68 mg/L), SHLA-G (10.68±1.74μg/L), and MMIF (2.01±0.42 ng/ml) of the women in the study group were significant higher than those of the women in the control group. The serum levels of PAI-1, SHLA-G, and MMIF of the women with II stage of Ems were the lowest, and then followed by those of the women with III stage of Ems, and those of the women with IV stage of Ems were the highest. The serum levels of the PAI-1, the SHLA-G, and the MMIF of the women with mild dysmenorrhea were the lowest, and then followed by those of the women with moderate dysmenorrhea, and those of the women with severe dysmenorrhea were the highest (all P＜0.05). The AUC of the PAI-1 level for predicting Ems was 0.983, and its 95%CI was 0.935-1.000. The AUC of the sHLA-G level for predicting Ems was 0.986, and its 95%CI was 0.975-0.993. The AUC of MMIF for predicting Ems was 0.981, and its 95%CI was 0.959-0.992. The AUC of combined detection levels of the PAI-1, the sHLA-G, and the MMIF for predicting Ems was 0.996, and its 95%CI was 0.993-1.000, which were significant higher than those of the PAI-1 level, the sHLA-G level, or the MMIF level alone (P＜0.05).The specificity (93.2%) and the accuracy (94.3%) of combined detection levels of the PAI-1, the sHLA-G, and the MMIF for predicting Ems were both significant higher than those of the PAI-1 level, the sHLA-G level, or the MMIF level alone. Conclusion: The expression levels of serum PAI-1, SHla-g, and MMIF of the women with Ems are closely related to their different stages of Ems and their severe degree of dysmenorrhea, so the levels of the serum PAI-1, SHla-g, and MMIF have high predictive value for Ems.
