RÉSUMÉ
Objective:To discuss clinical effect of Zhuyu Zhixuetang to chronic endometritis (CE) with syndrome of Qi deficiency and blood stasis and to study improvement effect to pregnancy outcome. Method:One hundred and forty-four patients were randomly divided into two groups, patients in control group were 72 cases and in observation group were 72 cases. In control group, 66 patients completed the therapy because of 4 falling off or missing visit and 2 eliminated, and in observation group, 65 patients completed the therapy because of 3 falling off or missing visit and 5 eliminated. In two groups. anti-infection treatment was gicen to patients. Patients in control group got Fuke Qianjin Pian, 6 tablets/time, 3 times/day. Patients in observation group got Zhuyu Zhixuetang, 1 dose/day. The treatment was continued for 3 months and the follow up was recorded for 6 months. Before and after treatment, changes of menstrual volume, period and cycle were recorded. And hysteroscopy and color Doppler ultrasound of vagina were made, and endometrial morphology and endometrial receptivity were evaluated [endometrial thickness, resistance index (RI), pulsation index (PI) and blood flow index (FI)] were evaluated, and pathology of endometrial were tested. And scores of syndrome of Qi deficiency and blood stasis were graded, levels of interleukin-1 <italic>β</italic> (IL-1<italic> β</italic>), IL-6 and tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>) and T-lymphoid subsets (CD3<sup>+</sup>, CD4<sup>+</sup>, CD8<sup>+</sup>) in peripheral blood were measured. Pregnancy and miscarriage were recorded and the safety was evaluated. Result:After treatment, menstrual volume, menstrual period, cycle and complete normal rate of menstruation in observation group were all higher than those in control group (<italic>P</italic><0.05). Endometrial thickness and FI were more than those in control group (<italic>P</italic><0.01), RI and PI were lower than RI and PI in control group (<italic>P</italic><0.01). And compared with control group, levels of IL-1<italic>β</italic>, IL-6, TNF-<italic>α</italic> and CD8<sup>+ </sup>were less (<italic>P</italic><0.01). And levels of CD3<sup>+</sup>, CD4<sup>+</sup> and CD4<sup>+</sup>/ CD8<sup>+</sup> were higher than the data in control group (<italic>P</italic><0.01). During 6 months follow-up, pregnancy rate in observation group was 46.97% (31/66) was higher than 27.69% (18/65) in control group (<italic>χ</italic><sup>2</sup>=5.197, <italic>P</italic><0.05). Total effective rate of endometrial morphology was 96.97% (64/66) higher than 86.15% (56/65) in control group (<italic>χ</italic><sup>2</sup>=4.981, <italic>P</italic><0.05). Total effective rate endometrial pathology was 95.45% (63/66) higher than 84.62% (55/65) in control group (<italic>χ</italic><sup>2</sup>=4.304, <italic>P</italic><0.05). Total effective rate of comprehensive clinical effect was 93.94% (62/66) higher than 81.54% (55/65) in control group (<italic>χ</italic><sup>2</sup>=4.696, <italic>P</italic><0.05). There was no adverse reactions related to traditional Chinese medicine. Conclusion:Zhuyu Zhixuetang can regulate menstruation, relieve clinical symptoms, improve endometrial morphology under hysteroscopy, regulate systemic and local immune inflammatory response, improve CP, thus improve pregnancy outcome, with better comprehensive effect and safety.
