RESUMO
Objective To investigate the dynamic changes and its significance of inflammatory factors in cervical secretions and prior cervical tissues after cervical conical resection.Methods Women who received prior cervical conization during December 2013 and December 2015 in this hospital were selected,then the cervical tissue and secretion were collected regular interval after the conization.The expression of tumor necrosis factor-α(TNF),interleukin 6 (IL-6) and high mobility group protein 1 (HMGB1) were quantitative detected and analyzed.The expression and infiltration of inflammatory cell were detected by HE and immunohistochemical staining.Results The expression of TNF-α,IL-6 and HMGB1 in cervical tissues and secretions increased gradually after priorcervical conization,which reached the peak at 1 to 2 weeks after priorcervical conization,and then gradually decreased,the differences were statistically significant when compared with the preoperative control group (P＜0.05).The inflammatory cell infiltration and the inflammatory response were most severe at 1st week after the conization.The expression of TNF-α,IL 6 and HMGB1 was at 1st week after the conization were significantly higher than that of the 4thweek group.Conclusion The cervical inflammatory were most severe after the prior cervical conization about 1-2weeks,and the hysterectomy should be avoided at this stage.
