Abstract:
Objective To explore the application value of serum CXC chemokine ligand 12(CXCL12)and CXC chemokine receptor 4(CXCR4)detection combined with Doppler ultrasound in the diagnosis of dangerous placenta previa.Methods A sum of 90 patients with dangerous placenta previa admitted to Cangzhou Hospital of Integrated Traditional Chinese Medicine and Western Medicine in Hebei from June 2020 to January 2023 were collected as research subjects.According to the postpartum pathological results,they were grouped into the placental implantation group(n=38)and the non placental implantation group(n=52),while another 90 healthy pregnant women(with placenta attached to the anterior wall of the uterus)who underwent pregnancy examination in Cangzhou Hospital of Integrated Traditional Chinese Medicine and Western Medicine in Hebei and matched with the patient's gestational age were regarded as the control group.The serum levels of CXCL12 and CXCR4 in each group were compared.ROC curve was applied to analyze the diagnostic efficacy of serum CXCL12 and CXCR4 levels for placental implantation.Using postoperative pathological results as the gold standard,the fourfold table method was applied to calculate the diagnostic efficacy of serum CXCL12 and CXCR4 combined with Doppler ultrasound in the occurrence of placental implantation.Results The serum levels of CXCL12(2.75±1.26 ng/ml,5.82±2.14 ng/ml,10.24±3.58 ng/ml)and CXCR4(1.84±0.78 ng/ml,4.47±1.83 ng/ml,8.32±2.763 ng/ml)in the control group,non placental implantation group and placental implantation group were increased successively,and the differences were significant(F=158.998,199.141,all P＜0.05).The detection of serum CXCL12 and CXCR4 combined with Doppler ultrasound in the diagnosis of placental implantation had an AUC of 0.948,and sensitivity and specificity were 92.11％and 86.54％,respectively,which was better than CXCL12,CXCR4,and Doppler ultrasound alone predicting separately(Z=2.266,2.682,3.472,P=0.023,0.007,0.001).Conclusion The expression levels of serum CXCL12 and CXCR4 in patients with dangerous placenta previa are increased.The combination of serum CXCL12 and CXCR4 with Doppler ultrasound may have good diagnostic efficacy for the occurrence of placental implantation in dangerous placenta previa patients.
