ABSTRACT
Objective:To investigate the clinical efficacy of Yunkang oral liquid combined with dexamethasone and low-molecular-weight heparin in the treatment of recurrent spontaneous abortion (RSA) complicated with pre thrombotic state (PTS), and its effects on thromboelastogram and serum progesterone, β-human chorionic gonadotropin (β- hCG), and helper T cell (Th) 1/Th2 cytokine levels in patients with recurrent spontaneous abortion (RSA).Methods:A prospective selection of 94 RSA patients with PTS admitted to the Baoding Second Central Hospital from January 2015 to December 2020 was conducted. They were randomly divided into two groups using a random number table method, with 47 patients in each group. The control group was treated with dexamethasone combined with low molecular weight heparin, while the observation group was treated with Yunkang oral liquid in addition to the control group. Continuously treat until 12 weeks of pregnancy to evaluate the efficacy of both groups and observe the adverse reactions in both groups. Two sets of thromboelastogram parameters were compared before and after treatment, including clot formation time (K value), clot reaction time (R value), and clot formation rate (α angle), maximum clot strength (MA value), and coagulation comprehensive index (CI), as well as serum progesterone β- hCG, Th1/Th2 cytokine levels. The pregnancy outcomes of the two groups were followed up.Results:The total effective rate of the observation group [95.7%(45/47)] was significantly higher than that of the control group [83.0%(39/47), P<0.05]. After treatment, the K and R values of both groups were significantly prolonged compared to before treatment (all P<0.05), the angle α, MA value, and CI value were significantly reduced compared to those before treatment (all P<0.05); After treatment, the K and R values in the observation group were significantly longer than those in the control group (al P<0.05), The angleα, MA value, and CI value were significantly lower than those of the control group (all P<0.05). After treatment, the levels of β- hCG serum progesterone of the two groups were significantly higher than those before treatment (all P<0.05), and The β-hCG levels of the serum progesterone were all higher than those in the control group (all P<0.05). After treatment, The levels serum Th1 cytokines [interferon-γ (INF- γ), tumor necrosis factor- α (TNF- α)] of both groups were significantly decreased compared to those before treatment (all P<0.05), and the levels of serum Th2 cytokines [interleukin-4, IL-10] were significantly increased compared to those before treatment (all P<0.05); After treatment, the observation group's serum IFN- γ, TNF- α were significantly lower than those of the control group (all P<0.05), and The levels of serum IL-4 and IL-10 were significantly higher than those of the control group all P<0.05). The live birth rate of the observation group was 87.2%(41/47), which was higher than that of the control group [70.2%(33/47)] ( P<0.05). There was no statistically significant difference in the adverse reaction rate between the observation group [6.4%(3/47)] and the control group [4.3%(2/47)] ( P>0.05). Conclusions:The treatment of RSA combined with PTS with Yunkang oral liquid, dexmedroxyprogesterone, and low molecular weight heparin can significantly alleviate blood hypercoagulability, increase reproductive endocrine hormone levels, regulate Th1/Th2 cytokine balance, improve live birth rate and clinical efficacy, and is safe and reliable.
