    • 摘要: 目的研究胚胎绒毛细胞培养及其核型分析在自然流产病因检测中的应用效果。方法选取2018年5月至2021年5月间阳江市妇幼保健院73例自然流产孕妇的绒毛细胞组织进行改良式长期培养与传代培养,在培养成功后将绒毛细胞进行染色体制备并进行核型检测,分析染色体核型检测结果和核型分布情况。结果本研究培养的73份样本中,原代培养共培养成功胚胎绒毛细胞65例,培养过程中出现8例污染未贴壁生长;但借助传代培养和备用培养基进行再次培养成功4例,4例培养失败,成功率为94.52%。69例细胞样本中检出染色体异常核型45例,占所有样本的65.21%;正常核型24例,占所有样本的34.78%。其中,常染色体三体共14例,占异常核型的31.11%;性染色体单体共9例,占异常核型的20.00%;双重三体共3例,占异常核型的6.67%;多倍体共10例,占异常核型的22.22%;嵌合体共5例,占异常核型的11.11%;结构异常共4例,占异常核型的8.89%。结论胚胎染色体异常是目前自然流产的主要病因之一,临床产科实践当中可以合理利用胚胎绒毛细胞染色体检查以有效判断自然流产病因,以便在合理的妊娠指导下达到优生优育的目的。

    • 摘要: 目的:分析辅助生殖技术致妊娠的早期自然流产绒毛染色体异常情况.方法:选取我院妇产科2015年10月—2019年10月收治的200例妊娠早期流产孕妇作为观察对象,根据受孕类型,分为A组(辅助生殖技术受孕)100例和B组(自然受孕)100例.分离、培养两组流产孕妇的绒毛细胞并进行分析,同时分析染色体情况.结果:A组染色体异常率为54.00%,B组染色体异常率为51.00%,两组比较差异无统计学意义(P>0.05).在染色体数量异常和结构异常方面,两组比较差异无统计学意义(P>0.05).在不同年龄层次染色体异常率方面,两组差异有统计学意义(P0.05).结论:辅助生殖技术所致妊娠早期流产,对自然流产胚胎染色体异常无明显影响,年龄可能是影响染色体异常的重要因素之一.

    • 摘要: Objective To investigate the relationships of sporadic and recurrent spontaneous a-bortion to cytogenetic abnormalities.Methods According to the number of abortion,178 preg-nant women with early spontaneous abortion((28.0±3.2)years of age)were divided into spo-radic spontaneous abortion group (n = 90,sporadic group)and recurrent spontaneous abortion group(n=88,recurrent group).The chorionic villi were obtained in uterine curettage and were cultured in situ for karyotyping.Results In sporadic group,chorionic villus culture was success-ful in 87 cases and unsuccessful in 3 cases.Among the 87 cases,39(45%)had chromosome nu-merical abnormalities,and 92% of them(36/39)had numerical abnormalities.In recurrent group, chorionic villus culture was successful in 86 cases and unsuccessful in 2 cases.Among the 86 ca-ses,48(56%)had chromosome numerical abnormalities,and 90% of them(43/48)had numerical numerical abnormalities.There were no significant differences in the rates of abnormal karyotype and type between the two groups(P >0.05).Conclusion Chromosomal numerical numerical ab-normalities,but not maternal age,are the primary cause of early spontaneous abortion.However, chromosome numerical abnormalities are not correlated with the number of abortion.The causes of recurrent embryonic chromosome numerical abnormalities need to be further studied.%目的:探讨偶发与复发自然流产的流产物细胞遗传学异常发生率相关性。方法选取178例发生早期自然流产孕妇,年龄(28.0±3.2)岁,按流产发生的次数分为偶发自然流产组(90例,偶发组)和复发自然流产组(88例,复发组)。孕妇在行清宫手术时取流产物绒毛组织,用原位培养方法培养并制备绒毛细胞染色体进行核型分析。结果偶发组3例培养失败,87例培养成功,异常核型39例(45%,39/87)中数目异常占92%(36/39);复发组2例培养失败,86例培养成功,异常核型48例(56%,48/86)中数目异常占90%(43/48)。2组流产物绒毛染色体核型异常率和异常类型比较差异无统计学意义(P >0.05)。结论早期胚胎染色体数目异常是导致早期流产的主要原因,与流产发生的次数无明显关系,母亲的年龄不是造成流产的最主要因素。导致多次妊娠均发生胚胎染色体异常的原因还待进一步研究。

    • 摘要: Objective To compare villus cell culture and karyotype analysis with single nucleotide polymorphism (SNP) microarray technology for the detection of chorionic villus chromosome in patients with retention of abortion.Methods Forty cases were analyzed with the two methods.Results Chorionic villus culturing was successful in 29 cases,among which 10 were found to have an abnormal karyotypes.For the SNP microarray analysis,all 40 cases were successful,among which 16 were shown to have an abnormal molecular karyotype.Conclusion SNP microarray technology is highly accurate and specific,which is particularly suitable for the detection of chromosomal deletions or duplications,uniparental disomy,lowpercentage mosaicism and other chromosomal abnormalities.It has provided an effective supplement to the conventional chorionic villus culture and karyotype analysis.%目的 比较用绒毛细胞培养核型分析与单核苷酸多态性(single nucleotide polymorphism,SNP)微阵列技术对稽留流产绒毛进行染色体检测的优缺点.方法 对确诊为稽留流产的40位孕妇应用上述两种方法检测绒毛染色体.结果 绒毛培养成功29份,发现核型异常10例;SNP微阵列均检测成功,发现异常分子核型16例.结论 SNP微阵列检测准确率高,特异性强,尤其能检测微缺失或重复、单亲二倍体、低比例嵌合体等染色体异常,是对传统的绒毛细胞培养核型分析的有效补充.

    • 摘要: Objective To evaluate the value of chorionic villus cells karyotype analysis in prenatal diagnosis during the first tri-mester of pregnancy.Methods Pregnant women with prenatal diagnosis indications were punctured by guiding abdominal B-mode ultrasound to get villi tissue which was then to develop cell culture,chromosome preparation and karyotype analysis.Results A to-tal of 1 140 cases were successfully cultured,and the successful cultivating rate was 98.2% (1 140/1 160).Among them,chromo-somes of 62 cases were detected to be non-polymorphic structural abnormalities,including 32 abnormal chromosome number,5 chro-mosome balanced translocation,3 chromosome deletion,and 22 chimeras.What′s more,20 cases were detected to be chromosomal inversion,19 cases of chromosome 9 were inversion,and one with chromosome Y was inversion.Conclusion Karyotype analysis of villus cell could help to detect fetal chromosomal abnormalities during early pregnancy and get early intervention.It was significant to reduce the child′s birth with chromosome abnormalities.%目的:评价绒毛细胞染色体核型分析在孕早期产前诊断中的应用价值。方法对有产前诊断指征的孕妇在 B 超引导下经腹绒毛穿刺抽取绒毛组织行细胞培养、染色体制备及核型分析。结果成功培养绒毛细胞1140例,成功率为98.2%(1140/1160),共检测出62例染色体非多态性结构异常。其中包括32例染色体数目异常,5例染色体平衡易位,3例染色体缺失,22例嵌合体。同时还检测出20例染色体倒位,包括19例9号染色体倒位,1例 Y 倒位。结论孕早期绒毛细胞染色体检查能及早发现胎儿染色体异常并早期干预,对于减少染色体畸形儿的出生具有重要的意义。

    • 摘要: Objective To investigate the clinical relationship between villus cells chromosome abnormality and spontaneous a-bortion in early pregnancy.Methods Villus cells from 112 women who just had spontaneous abortion in early pregnancy were cul-tured and prepared for karyotype analysis.Results 105 specimens were anaIyzed successfully which accounted for 93.75%(105/112).Among them 50 specimens were normal karyotype which accounted for 47.62%(50/105),55 cases were abnormal karyotype accounted for 52.38%(55/105).Abnormal number was the major type of abnormal karyotype.Among them there were 33 cases of trisomy which were most common,6 cases of triploid,1 case of tetraploid and 1 case of compound,2 cases of chimera,1 case of sex-ual chromatids and 6 cases of structural abnormalities.In the specimens with normal karyotype,20 cases were from male,30 cases were from female.Conclusion Embryo chromosome abnormality is one of the factors causing early pregnancy spontaneous abor-tion.Conduct villus chromosome examination in clinical treatment is useful to determine the reasons of abortion and to guide the next pregnancy.%目的:探讨绒毛细胞染色体异常与妊娠早期自然流产间的临床关系。方法对112例妊娠早期自然流产患者绒毛细胞进行短期培养、染色体制备及核型分析。结果成功检测绒毛标本105例,占93.75%(105/112)。其中,检出正常核型50例,占47.62%(50/105);异常核型55例,占52.38%(55/105)。异常核型中以数目异常为主,其中三体型最为常见(33例),三倍体6例,四倍体及复合三体各1例,嵌合体2例,性染色单体1例,结构异常6例,另有染色体正常变异5例;正常核型中男性20例,女性30例。结论胚胎染色体异常是导致妊娠早期自然流产的重要因素之一,临床上开展流产绒毛染色体检查有利于判断本次流产原因,合理指导下次妊娠。
