The invention relates to an application of a NeuMME subgroup in preparation of a diagnostic kit for evaluating NETosis occurrence degree or endometriosis severity. The invention also provides an application of the NETosis inhibitor or the DNase I in preparation of a medicine for treating endometriosis. It is proved that NETs in the abdominal cavity promote colonization, migration and proliferation capacity of endometrial cells through the capture effect, so that occurrence and development of endometriosis focuses are promoted, the NeuMME subgroup is a main source of the NETs, and therefore detection of the NeuMME subgroup and evaluation of the occurrence degree of NETosis have important significance. In addition, based on clinical sample analysis, it is found that NeuMME subgroups of peritoneal fluid are closely related to clinical rASRM scores of endometriosis; the analysis of a mouse endometriosis model also finds that the NeuMME subgroup is closely related to the occurrence and development of an endometriosis focus. Therefore, the NeuMME-based subgroup detection for evaluating the severity of endometriosis and the focus progress has remarkable advantages and application prospects. The development of endometriosis can be remarkably inhibited by inhibiting NETosis or clearing NETs in a mouse model through a drug.
