Exclusion criteria were: age \>40 years; history of second-trimester miscarriage or cervical insufficiency; ovarian dysfunction or prior ovarian surgery; uterine malformation; conditions associated with abnormal uterine cavity morphology; abnormal cervical morphology or function, or history of cervical surgery; refractory vaginitis; multiple pregnancy; severe medical or surgical comorbidities; participation in another clinical trial within 90 days before randomization, or use of an investigational drug within 30 days; inability or poor compliance for long-term follow-up; and any other condition that, in the investigator's judgment, could interfere with trial implementation or outcome evaluation.

Control group: The administration of vaginal progesterone (90mg/d) began from positive HCG in blood/urine until 12 weeks of gestation. Regular delivery examinations were conducted, and cervical length was detected by B-ultrasound at 12, 16, 20 and 24 weeks of gestation respectively, while fetal growth and development were monitored. Follow-up was continued until the end of delivery.
