Autosomal dominant polycystic kidney disease (ADPKD) is a most common inherited renal disease, about 50% with a family history, although the exact etiology not yet clear. To date, ADPKD, a multisystem disorder without effective preventive and therapeutic means, has been shown to be detrimental to human health. Recent studies show that severe oligoasthenozoospermia, necrospermia, immotile sperm, azoospermia, epididymal cyst, seminal vesicle cyst, and ejaculatory duct cyst found in male ADPKD patients may lead to male infertility, though the specific mechanisms remain unknown. Structural anomaly of spermatozoa, defect of polycystin, mutation of PKD genes, and micro-deletion of the AZF gene could be the reasons for the higher incidence of abnormal semen quality in male ADPKD patients. Assisted reproductive techniques can increase the chances of pregnancy, whereas the health of the offspring should be taken into consideration. This article presents an overview of reproductive issues concerning infertile male ADPKD patients from the perspective of the morbidity, pathophysiological mechanism, diagnosis, and management of the disease.

Objective To evaluate the efficacy of minimally invasive percutaneous intervertebral disc approach for treatment of sympathetic cervical spondylosis. Methods Fifty?six patients diagnosed as having sympathetic cervical spondylosis from January 2009 to August 2014, aged 22-64 yr, with the dis?ease course ranged from 6 months to 15 yr and a follow?up period of 6 months, were enrolled in the study. The related minimally invasive approach was selected according to the height of the diseased intervertebral space. When the ratio of the height of diseased intervertebral space∕normal intervertebral space≤1∕3, per?cutaneous radiofrequency ablation was used ( groupⅠ, n=19); when the ratio within the range of 1∕3-2∕3, percutaneous laser disk decompression was used ( groupⅡ, n=12); when the ratio≥2∕3, low?tem?perature plasma radiofrequency ablation was used ( group Ⅲ, n=25) . Before operation, at 2 weeks after operation, and at 1, 3 and 6 months after operation, the sympathetic symptoms were evaluated using the 20?point score. At 2 weeks and 6 months after operation, the patients′ subjective satisfaction was assessed and graded ( excellent, good, medium and poor ) . Results All the patients were followed up for 6 months. The sympathetic symptom scores were significantly lower at each time point after operation in Ⅰand Ⅲ groups and at 2 weeks and 3 and 6 months after operation in group Ⅱ than those before operation
( P<0.05) . The excellent and good rate of patients′subjective satisfaction was 67.9% at 2 weeks after op?eration, and 76.8% in the last follow?up period at 6 months after operation. Conclusion The minimally invasive percutaneous intervertebral disc approach has a marked short?term effect on sympathetic cervical spondylosis.

BACKGROUND:Posterior stabilized femoral knee prosthesis needs additional condyle osteotomy to accommodate the tibial post and femur fossa structures. Intercondylar fossa on both sides connected at the femoral body with concentrated stress is a place easily affecting fractures. Differences in bone mass between different models of different brands did not have specific data, which was not convenient to select prosthesis for clinicians.
OBJECTIVE: To compare the difference of intercondylar osteotomy data among clinical commonly used posterior stabilized knee prostheses (six imported and domestic brands), and to provide basis for the selection and application of the prostheses.
METHODS:The current commonly used posterior stabilized knee prostheses (six imported and domestic brands) were used, including Zimmer NexGen LPS, Stryker Scrorpio NRG Knee-Flexed, Depuy PFC Sigma, Smith & nephew Genesis-2 PS, United-U1 and Wego GKPS. According to the osteotomy template, the osteotomy-surfaces consisting of femoral condyle starting section and cross section, distal section of femoral condyle, and back-oblique section were identified. The corresponding femoral prosthesis diameter lines included condylar ambilateral and anteroposterior diameters, width and depth of femoral intercondylar fossa. The above data were compared and measured.
RESULTS AND CONCLUSION:The six kinds of knee femoral prostheses were different in ratio of ambilateral diameter and anteroposterior diameter, bone resection of intercondylar fossa, and geometry. Imported prostheses carry shorter diameters in femoral starting and cross sections, so it can catch more posterior condylar osteotomy. With increasing prosthesis sizes, the ratio of bone loss causing by width of intercondylar osteotomy is decreased among six brands. In al sizes, Stryker Scrorpio NRG Knee-Flexed catches shorter width of intercondylar osteotomy. Knee prosthesis osteotomy among six brands is different. The result of this study is not sufficient to evaluate the pros and cons between different prostheses, but as reserving bone is concerned, the design of less intercondylar osteoomy catches more advantages.
