[The fetus protection effects of Zhixue Baotai Decoction on women of early threatened abortion with dark area surrounding pregnancy sac].
To observe the fetus protection effects of Zhixue Baotai Decoction (ZBD) on women of early threatened abortion with dark area surrounding pregnancy sac.
                The 105 patients with early threatened abortion, in whom vaginal bleeding was shown already, were randomly assigned to the treatment group and the control group, who were treated respectively with ZBD and progesterone to protect fetus. The efficacy of treatment was evaluated by dynamic monitoring of serum hormone and B-ultrasonic examination.
                Among the 54 cases in the treatment group the fetus was protected successfully, showing a fetus protecting rate of 81.5%; while among the 51 cases in the control group, the protection was effective in 22 cases (43.1%), the success rate in the former was better (P<0.01). The dark area was absorbed in 16 out of 19 cases (84.2%) in the treatment group, while in the control group absorption occurred only in 6 out of 17 (35.3%).
                The effect of ZBD is superior to that of progesterone in treating women of early threatened abortion with dark area surrounding pregnancy sac.
