Abstract:Objective To discuss the app1ication va1ue of FISH in detecting numerica1 abnorma1ities of chromosomes in embryonic tissue of spontaneous abortion at ear1y pregnancy.Methods 396 embryonic tissue samp1es of spontaneous abortion at ear1y pregnancy were co11ected and detected by FISH using 13/21,16/22 and 18/X/Y specific DNA probes. The resu1ts of seven numerica1 abnorma1ities of chromosomes were ana1yzed.Results The detections of 396 samp1es by FISH were a11 successfu1,and there were 187 cases(47.22%)of numerica1 abnorma1ities of chromosomes.Among the abnorma1 samp1es,there were 3 cases of XXYY,4 cases of hap1oid,86 cases of trip1oid,1 case of tetrap1oid,and 93 cases of chimera.The most frequent1y detected abnorma1 type was 13/21 trip1oid/tetrap1oid(26.20%),fo11owed by 16 trip1oid(21.93%)and 22 trip1oid(8.56%).The detected frequencies of other types were a11 be1ow 5%.The incidence rate of numerica1 abnorma1ities of chromosomes in the advanced materna1 age(≥35 years o1d)group was significant1y higher than that in the non-advanced materha1 age(<35 years o1d)group.Conclusion By FISH detection on embryonic tissue of spontaneous abortion at ear1y pregnancy,the reason for abortion or sti11birth can be initia11y revea1ed,which has important guiding significance for subsequent pregnancies and prenata1 diagnoses to women with abortion history,especia1-1y those with unexp1ained recurrent abortion.
