Objective To analyze the internal and external factors of the portable integrated remote medical examination chest during military medical support to facilitate telemedicine service in the military hospital.Methods The self-developed chest had its advantages, disadvantages, opportunities and threatening factors analyzed qualitatively with SWOT method. Results The chest had advantages in meeting military and practical requirements as well as fulfilling military-civilian integration, disadvantages in deficiency of specialized mobile network, specific signs acquisition devices and mature operation mechanism, opportunities in national health program, military development and mobile internet as well as the threatening factors in non-unified interface standard,untimely policy issuing and unclear definition of responsibility,rights and interests.Conclusion Considerations have to be taken on internet application and policy institution to facilitate military telemedicine support.

ObjectiveTo assess the effects of testicular sperm and epididymal sperm on the outcomes of ICSI for patients with obstructive azoospermia.

METHODSWe searched PubMed, MEDLINE, EMBASE, Cochrane, CNKI, VIP, CBM, and Wanfang Database up to December 2015 for published literature relevant to ICSI with testicular or epididymal sperm for obstructive azoospermia patients. According to the inclusion and exclusion criteria, two reviewers independently conducted literature screening, data extraction and quality assessment of the included trials, followed by meta-analysis with the RevMan 5.3 software.

RESULTSA total of 14 studies were identified, involving 1 278 patients and 1 553 ICSI cycles. ICSI with epididymal sperm exhibited a significantly higher fertilization rate than that with testicular sperm (RR = 1.08, 95% CI 1.05－1.11, P<0.01). No statistically significant differences were observed between the epididymal and testicular sperm groups in the rates of cleavage (RR = 1.04, 95% CI 0.99－1.10, P = 0.13), good-quality embryo (RR = 1.01, 95% CI 0.93－1.09,P = 0.85), implantation (RR = 1.14, 95% CI 0.75－1.73, P = 0.55), clinical pregnancy (RR = 1.14, 95% CI 0.98－1.31, P = 0.08), and miscarriage (RR = 0.86, 95% CI 0.53－1.39,P = 0.54).

CONCLUSIONSICSI with epididymal sperm yields a markedly higher fertilization rate than that with testicular sperm, but has no statistically significant differences from the latter in the rates of cleavage, good-quality embryo, implantation, clinical pregnancy, and miscarriage in the treatment of obstructive azoospermia.
