摘　　要：Objective To explore the influence of galectin-3 on missed abortion. Methods Forty cases of normal intrauterine early pregnancy were randomly divided into 2 groups： surgical abortion group （group A, n=20） and medical abortion group （group B, n =20）. The third group was missed abortion group （group C, n =20） with the gestational age less than 13 weeks. Serum was isolated from the blood samples, collected and used for ELISA quantification of galectin-3. Villus and decidua tissues were collected from the abortus for immunohistochemical examination and real-time fluorescence relative quantitative PCR. Results The level of galectin-3 in the serum was the lowest in missed abortion group （P〈0.05）. Immunohistochemistry showed that galectin-3 expression in villus of missed abortion group was significantly lower than that of surgical abortion group （P〈0. 01）. Real-time fluorescence relative quantitative PCR showed that galectin-3 mRNA relative expression in villus of missed abortion group （2^-△△Ct=0. 04± 0. 01） was significantly lower than that of surgical abortion group （2^-△△Ct=1.00 ± 0.00）. Galectin-3 mRNA relative expression in deciduas of medical abortion group （2-zact=o. 08 ± 0.02） was s!gnificantly lower than that of surgical abortion group （2^-△△Ct=1.00 ± 0.00） （P〈0. 01）. Conclusion Galectin-3 is related to the development of villus and decidua during early pregnancy. The decreased expression of galectin-3 may promote the occurrence of missed abortion.Objective To explore the influence of galectin-3 on missed abortion.
