OBJECTIVETo search for the optimal strategies for sperm collection from the patient with temporary penile erectile dysfunction (ED) on the day of oocyte pick-up ( OPU) in in vitro fertilization embryo transfer (IVF-ET).

METHODSWe retrospectively analyzed 93 cases of temporary ED on the OPU day of IVF-ET from January 2011 to May 2014, with fresh semen for 45 cases (group A), cryopreserved sperm before oocyte retrieval for 30 cases (group B), and frozen oocytes for 18 cases (group C). Group A was again subdivided into A1 (n = 18) and A2 n = 27) , the former intervened with oral sildenafil while the latter left untreated. We compared the rates of fertilization, high-quality embryo, and pregnancy among different groups.

RESULTSNo statistically significant differences were found among groups A, B and C in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and rates of cleavage, or in the percentages of normal fertilization (80.78% vs 80.43% vs 84.77%), high-quality embryo (53.27% vs 52.97% vs 47.69%) and pregnancy (60.00% vs 56.77% vs 44.44%) (all P > 0.05). The rate of 3PN was markedly lower in group C (0.63%) than in A (9. 61%) and B (4.34%) (P < 0.05). There were no significant differences between groups A1 and A2 in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and the rates of fertilization, cleavage, high-quality embryo, and pregnancy (all P > 0.05).

CONCLUSIONOn the OPU day of IVF-ET, oral sildenafil can help temporary ED men to achieve penile erection and ejaculation without affecting the outcomes of assisted reproduction. Cryopreserved sperm can be used in case of predicted temporary ED and frozen oocytes can also be employed if sperm retrieval fails. However, to avoid puncture injury to the epididymis or testis, fresh semen should be the first choice.

β-myosin heavy chain mutations are the most frequently identified basis for hypertrophic cardiomyopathy (HCM). A transgenic mouse model (αMHC(403)) has been extensively used to study various mechanistic aspects of HCM. There is general skepticism whether mouse and human disease features are similar. Herein we compare morphologic and functional characteristics, and disease evolution, in a transgenic mouse and a single family with a MHC mutation. Ten male αMHC(403) transgenic mice (at t-5 weeks, -12 weeks, and -24 weeks) and 10 HCM patients from the same family with a β-myosin heavy chain mutation were enrolled. Morphometric, conventional echocardiographic, tissue Doppler and strain analytic characteristics of transgenic mice and HCM patients were assessed. Ten male transgenic mice (αMHC(403)) were examined at ages -5 weeks, -12 weeks, and -24 weeks. In the transgenic mice, aging was associated with a significant increase in septal (0.59±0.06 vs. 0.64±0.05 vs. 0.69±0.11 mm, P<0.01) and anterior wall thickness (0.58±0.1 vs. 0.62±0.07 vs. 0.80±0.16 mm, P<0.001), which was coincident with a significant decrease in circumferential strain (-22%±4% vs. -20%±3% vs. -19%±3%, P=0.03), global longitudinal strain (-19%±3% vs. -17%±2% vs. -16%±3%, P=0.001) and E/A ratio (1.9±0.3 vs. 1.7±0.3 vs. 1.4±0.3, P=0.01). The HCM patients were classified into 1st generation (n=6; mean age 53±6 years), and 2nd generation (n=4; mean age 32±8 years). Septal thickness (2.2±0.9 vs. 1.4±0.1 cm, P<0.05), left atrial (LA) volume (62±16 vs. 41±5 mL, P=0.03), E/A ratio (0.77±0.21 vs. 1.1±0.1, P=0.01), E/e' ratio (25±10 vs. 12±2, P=0.03), global left ventricular (LV) strain (-14%±3% vs. -20%±3%, P=0.01) and global LV early diastolic strain rate (0.76±0.17 s(-1) vs. 1.3±0.2 s-1, P=0.01) were significantly worse in the older generation. In β-myosin heavy chain mutations, transgenic mice and humans have similar progression in morphologic and functional abnormalities. The αMHC(403) transgenic mouse model closely recapitulates human disease.

OBJECTIVESTo explore the clinical features of traumatic atlantoaxial instability combined with subaxial cervical spinal cord injury (CSCI), and to analyze the feasibility, indication and therapeutic effects of anterior-posterior approach in such cases.

METHODSFrom March 2004 to September 2009, 16 cases with this trauma were admitted and surgically treated in our department. Before surgery, skull traction was performed. Posterior atlantoaxial pedicle screw internal fixation and bone graft fusion were conducted to manage traumatic atlantoaxial instability. As for subaxial CSCI, anterior cervical corpectomy or discectomy decompression, bone grafting and internal fixation with steel plates were applied.

RESULTSAll operations were successful. The average operation time was 3 hours and operative blood loss 400 ml. Satisfactory reduction of both the upper and lower cervical spine and complete decompression were achieved. All patients were followed up for 12 to 36 months. Their clinical symptoms were improved by various levels. The Japanese Orthopaedic Association (JOA) scores ranged from 10 to 16 one year postoperatively, 13.95+/-2.06 on average(improvement rate equal to 70.10%). X-rays, spiral CT and MRI confirmed normal cervical alignments, complete decompression and fine implants'position. There was no breakage or loosening of screws, nor exodus of titanium mesh or implanted bone blocks. The grafted bone achieved fusion 3-6 months postoperatively and no atlantoaxial instability was observed.

CONCLUSIONSTraumatic atlantoaxial instability may combine with subaxial CSCI, misdiagnosis of which should be especially alerted and avoided. For severe cases, one stage anterior-posterior approach to decompress the upper and lower cervical spine, together with reposition, bone grafting and fusion, as well as internal fixation can immediately restore the normal alignments and stability of the cervical spine and effectively improve the spinal nervous function, thus being an ideal approach.

OBJECTIVETo investigate the relationships between rs3865418 polymorphism of neural precursor cell expressed developmentally downregulated 4-like gene and obesity in Kazakh general population.

METHODSBased on a cross-sectional epidemiological study in a Kazakh general population, a case-control study was conducted. The rs3865418 polymorphism in a Kazakh general population (856 subjects, including 364 males and 492 females; 478 in obesity group and 378 in normal control group) was genotyped by TaqMan polymerase chain reaction, and the relationship between rs3865418 polymorphism and obesity was analyzed.

RESULTSThe rs3865418 polymorphism was successfully genotyped in 851 Kazakh subjects. The distribution of the genotypes and alleles of rs3865418 polymorphism did not differ significantly between the obesity group and normal control group in terms of general populations, males, and females (all P > 0.05). The waist circumference showed a tendency of C/C > C/T > T/T in males and C/C < C/T < T/T in females, but without statistical significance (P > 0.05).

CONCLUSIONSThe rs3865418 polymorphism of neural precursor cell expressed developmentally downregulated 4-like gene may not be associated with obesity in Kazakh general population. In other words, it is not a predisposing factor for obesity in Kazakh.
