目的　评价血小板表面糖蛋白受体 (GPⅡb/Ⅲa)拮抗剂ReoPro对硝酸甘油不能缓解的冠状动脉无血流现象(No -Reflow)的疗效以及对住院期间临床预后的影响。方法　回顾性研究了伴或不伴No -Reflow现象病人的临床特点、住院期间主要心血管事件 (死亡、心肌梗死、血管再通术 )发生率。结果　 10 93例病人中经皮球囊扩张术 (PTCA) 35 2例 ,支架术 741例 ;共 2 3例病人被描述有No -Reflow现象 ,其中 6例病人对硝酸甘油冠状动脉内注射无反应 ,在给予ReoPro后TIMI血流明显改善 (0 83± 0 41vs 2 5 0± 0 5 4,P 0 75 )、靶血管再介入 (0vs 1 10 % ,P >0 75 )、搭桥术 (0vs 0 2 1% ,P >0 90 )发生率无区别 ,但心肌梗死发生率较高 (Q波心肌梗死 :16 7%vs0 37% ,P <0 0 0 5 ;无Q波心肌梗死 :5 0 %vs 1 0 5 % ,P <0 0 0 5 )。结论　ReoPro能明显改善对硝酸甘油无反应No -Reflow病人的TIMI血流及临床预后 ,也提示血小板介导的微血管血栓及栓塞是这类病人No

Motility of Stallion Spermatozoa after Centrifugation and Cooling in INRA96 or Walworth Extender

引用

Journal of Agricultural Science and Technology(A) 2016年第2期6卷 143-147页

A total of 18 ejaculates were collected, once per week, from six fertile stallions for three consecutive weeks in October and November, to compare motility over time between extenders using four semen processing treatments. Four total aliquots of semen were used. Two aliquots of each semen collection were extended in either INRA96 or an experimental proprietary milk-based extender Walworth （WW） extender, and each was designed for multi-day storage of fresh chilled semen. Each aliquot was divided again, and either centrifuged at 600 μg for 10 min without cushion, or not centrifuged and extended to a final concentration of 25 × 10^6 spermatozoa/mL. The treatments evaluated were INRA96 without centrifugation （INRA-NC） or with centrifugation （INRA-C）, and Walworth extender without centrifugation （WW-NC） or with centrifugation （WW-C）. Total and progressive motility were measured using Sperm Vision~ CASA at 0, 24, 48 and 72 h post-collection. Samples were stored at 4 ℃. No differences were found between extenders in progressive （P = 0.13） or total motility （P = 0.14） over the four different time points without centrifugation. However, ejaculates processed in INRA-C group had the greater total and progressive motility （P 〈 0.05） over the four time points than ejaculates in the WW-C group. It was found that centrifugation and re-suspension of stallion semen in INRA96 improved the longevity of fresh chilled semen. However, when not using centrifugation, the Walworth extender proved to be as effective for maintaining spermatozoa motility across all time points as 1NRA96 , and may be an alternative for use in the equine breeding industry.
