Application of array comparative genomic hybridization in prenatal diagnosis of a case with 5q35 deletion syndrome / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To use combined G-banding and array-comparative genomic hybridization (aCGH) for the prenatal diagnosis of a fetus with 5q35 deletion syndrome.</p><p><b>METHODS</b>Chromosomal karotypes of the fetus and parents were analyzed with G-banding analysis. aCGH was performed to detect minor chromosomal structural abnormalities.</p><p><b>RESULTS</b>The karyotype of the fetus was ascertained as 46, XY, t(5;10)(q35;p13), and the karyotypes of the parents were normal. aCGH has identified a de novo 1.68 Mb deletion at 5q35.2q35.3 and a 1.44 Mb duplication at 10p14p13.</p><p><b>CONCLUSION</b>aCGH has a higher resolution and greater accuracy for mapping chromosomal aberrations and is a useful supplement for G banding karyptyping analysis.</p>

Bipolar plasmakinetic enucleation and resection of prostate for 120 benign prostatic hyperplasia patients / 中国医师进修杂志

Objective To evaluate the surgical effects and methods of bipolar plasmakinetic enucleation and resection of prostate for benign prostatic hyperplasia (BPH). Methods A total of 120 patients with BPH were performed bipolar plasmakinetic resection of prostate and bipolar plasmakinetic enucleation of prostate for BPH. The blood loss,operative time,catheterization time,hospital stay and complications were monitored and analyzed. Results All of the patients were operated successfully. All the cases were followed up for 3-6 months. No urethral stricture, bladder neck contracture, rebleeding, permanent urinary incontinence occurred. The maximum flow rate increased from (6.1 ± 2.5) ml/s peroperative to (16.3 ± 2.2) ml/s at 3 months postoperative,and international prostate symptoms score (IPSS) decreased from (23.8 ± 5.2) scores peroperative to (4.6 ± 3.9) scores (P < 0.01). Conclusion Bipolar plasmakinetic enucleation and resection of prostate for BPH has many advantages such as thorough excision of the prostate,less blood loss in operation,less operation time and complications, higher security and quicker recovery, so it deserves clinical application.
