目的探讨盆腔炎患者血清Th1/Th2及外周血T淋巴细胞亚群的变化情况。方法选取2015年1月-2016年1月在该院进行诊断与治疗的56例盆腔炎患者为观察组,另选取同期56名体检健康的同龄妇女为对照组。比较两组血清Th1/Th2指标及外周血T淋巴细胞亚群指标的差异,并比较观察组中不同严重程度与疾病分类盆腔炎患者的检测结果。结果观察组患者血清IL-2及CD4~+、CD3~+CD4~+水平低于对照组,其他血清Th1/Th2指标及外周血T淋巴细胞亚群指标均高于对照组,且急性盆腔炎患者差于慢性盆腔炎患者,重度患者差于轻度及中度患者,中度患者则差于轻度患者,差异均有统计学意义(P均<0.05)。结论盆腔炎患者血清Th1/Th2水平及外周血T淋巴细胞亚群呈现相对异常的状态,且盆腔炎的严重程度与分类对上述指标的表达影响较大。 Objective To investigate the changes of serum Th1 / Th2 and T lymphocyte subsets in patients with pelvic inflammatory disease. Methods Fifty-six patients with pelvic inflammatory disease diagnosed and treated in our hospital from January 2015 to January 2016 were selected as observation group and 56 healthy women of same age were selected as control group. The difference of serum Th1 / Th2 index and peripheral blood T lymphocyte subsets between the two groups were compared and the results of pelvic inflammatory disease with different severity and disease classification in the observation group were compared. Results The levels of serum IL-2, CD4 ~ + and CD3 ~ + CD4 ~ + in the observation group were lower than those in the control group. Th1 / Th2 index in other serum and T lymphocyte subsets in peripheral blood were higher than those in the control group, and acute pelvic inflammatory disease Patients with poorer chronic pelvic inflammatory disease, severe patients worse than mild and moderate patients, moderate patients were worse than mild patients, the differences were statistically significant (P all <0.05). Conclusions Serum levels of Th1 / Th2 and peripheral blood T lymphocyte subsets in patients with pelvic inflammatory disease are relatively abnormal, and the severity and classification of pelvic inflammatory disease have a significant impact on the above indicators.
