[Effect on immune factors and serum CA125 in patients of threatened abortion in early pregnancy complicated with subchorionic hematoma treated with auricular acupuncture combined with dydrogesterone].

To evaluate the therapeutic effect of auricular acupuncture combined with dydrogesterone for threatened abortion in early pregnancy complicated with subchorionic hematoma.A total of 80 patients were randomized into an observation group and a control group, 40 cases in each one. In the control group, dydrogesterone was taken orally twice a day, 10 mg a time until 12-week into pregnancy. In the observation group，auricular acupuncture was applied at penqiang (TF5), pizhixia (AT4), shen (CO10), xin(CO15), gan (CO12), jiaogan (AH6a) and neifenmi (CO18) on the basis of the control group, the auricular points on both sides were used alternatively. The auricular points were replaced every 3 days with 1 day break, totally 3 weeks (20 days) were required. Before treatment and after 10, 20 days of treatment, the percentage of helper T lymphocyte (Th) and inhibitory T lymphocyte (Ts), ratio of Th and Ts and serum level of CA125 were compared in the two groups. The areas of subchorionic hematoma and gestational sac were evaluated by B ultrasound. The therapeutic effect in the two groups were compared.The effective rate in the observation group was 80.0% (32/40), which was superior to 65.0% (26/40) in the control group (P<0.05). After 10, 20 days of treatment, the percentage of Th and ratio of Th and Ts were lower than before treatment, the percentage of Ts were increased in the two groups (P<0.01). After 20 days of treatment, the percentage of Th and ratio of Th and Ts in the observation group were lower than the control group (P<0.01), the percentage of Ts was higher than the control group (P<0.01). After 10, 20 days of treatment, the serum levels of CA125 were reduced compared before treatment in the two groups (P<0.01), and the serum levels of CA125 in the observation group were lower than the control group (P<0.01). After 10, 20 days of treatment, the ratio of subchorionic hematoma area and gestational sac area in the observation group was lower than the control group (P<0.01).Auricular acupuncture combined with dextroprogesterone can improve the effective rate of patients with threatened abortion in early pregnancy complicated with subchorionic hematoma, regulate immune factors, promote the hematoma absorption, and has a better synergistic effect with dextroprogesterone.
