RESUMO

Inhibin B(INHB) and anti-Müllerian hormone(AMH) detection have important clinical significance in assisted reproductive technology.INHB for evaluation of male testis function is very meaningful,playing a guiding role in the treatment of oligospermatism.INHB has very high clinical diagnosis value for evaluation of ovarian reserve function,being an important indicator to predict the effect of controlled ovarian hyperstimulation.AMH for evaluation of women ovarian function is significant,and is a diagnosis index of reproductive domain related diseases such as polycystic ovary syndrome and one of the important indices for evaluation of assisted reproductive outcomes.

RESUMO

Objective To explore the application of ultrasonography combined with hysteroscopy for the diagnosis of dated uterine false passage. Methods From May 2012 to May 2013, a total of 3437 cases were examined in the center by ultrasonic monitoring combined with hysteroscopic examinations.Dated uterine false passage was found in 4 cases.Under the guidance of ultrasonography, the hysteroscope was introduced into the uterine cavity.The ultrasonic probe was put at the site above the pubic symphysis for comprehensive examinations, with uterine distention fluid as reference. Results There were 2 cases of uterine anteversion and 2 cases of retroversion.There were 1 case of intracervical mouth stenosis, 1 case of intracervical mouth adhesion, and no intracervical mouth stricture or adhesion in 2 cases.The uterine false passage was located in the anterior wall in 2 cases and located in the back wall in 2 cases.The distance to serosal surface was about 3 mm at the thinnest place.The uterine false passage was 3-4 cm in depth. Conclusion Ultrasound monitoring combined with hysteroscopic examination can determine the part of the uterine endometrium line, improve the accuracy of diagnosis and treatment of intrauterine lesions.

RESUMO

Objective To investigate the prediction value of ultrasound endometrial pattern at the day of hCG administration on clinical outcome in patients undergoing in vitro fertilization-embryo transfer (IVF-ET).Methods 679 cycles of IVF-ET conducted between January 2011 and December 2012 in Beijing Obstetrics and Gynecology Hospital were reviewed retrospectively.All cycles were divided into three groups based on the endometrial pattern measured on the hCG day:group A (n =411) with triple line endometrium,group B (n =228) with no obvious triple line endometrium,group C (n =40) with homogeneous hyperechoic endometrium.Clinical outcomes such as implantation rate,pregnancy rate and miscarriage rate were analyzed.Results Among three groups,the implantation rates were 27.05%,20.33%,19.57%,respectively (x2 =9.04,P =0.01); the pregnancy rates were 34.31%,25.00%,12.50%,respectively (x2 =12.20,P =0.00).The implantation rate and pregnancy rate in group A were higher than the other two groups (P <0.05).The miscarriage rates were 16.31%,19.30%,40.00%,respectively(P > 0.05),there were no significant difference among them.Conclusions The ultrasound endometrium pattern on the day of hCG administration has predictive value on clinical outcome in patients undergoing in vitro fertilization-embryo transfer.

RESUMO

Objective To evaluate the application of domestic probe fluorescence in situ hybridization (FISH) in prenatal diagnosis on uncultured amniocytes aneuploid. Methods One thousand three hundred and sixty-nine uncultured amniocytes (16-24 gestational weeks) from 37 hospitals in China were selected for prenatal diagnosis. 5 chromosomes (21, 13, 18, X and Y) were detected with muhicolor FISH. In the mean time, cytogenetic karyotype analysis was performed as control. Results Of all the samples, 1361 samples were successfully tested by FISH, the rate of successful detection was 99.42% (1361/1369). Thirty-five samples were shown with abnormal karyotypes by domestic FISH probe, the abnormal rate is 2. 57% (35/1361 ), including trisomy 21 (22 samples), trisomy 13 (4 samples), trisomy 18(6 samples), X0 (1 sample) and XXY (2 samples). Results of both FISH and cytogenetic karyotype analysis exhibited extreme concordance. Conclusion Domestic FISH probe used in prenatal diagnosis on uncultured aminiocytes showed the following advantages, such as highly efficient, low cost, small amounts of samples needed and reliable results.

RESUMO

<p><b>OBJECTIVE</b>To establish a new diagnostic method for Down's syndrome using polymerase chain reaction (PCR).</p><p><b>METHODS</b>DNA extracted from five healthy individuals and five Down's syndrome patients was amplified in six specific tetranucleotide repeat loci on chromosome 21 using PCR. An accurate diagnosis was made by analyzing allelic distribution at each locus.</p><p><b>RESULTS</b>All Down's syndrome patients were identified as having at least two loci with three alleles, while none of the healthy individuals had three alleles. In addition, when two alleles were identified for a particular locus in the Down's syndrome samples, it was more likely that the intensity ratio between the two alleles was close to 2:1.</p><p><b>CONCLUSION</b>The molecular method can provide a fast, accurate, and economical alternation for the traditional cytogenetic diagnostic method for Down's syndrome.</p>
