单核细胞趋化蛋白-1在原发性急性闭角型青光眼患者房水中的表达及其与小梁切除术预后的关系

目的观察原发性急性闭角型青光眼(primary acute angle-closure glaucoma,APACG)患者房水中单核细胞趋化蛋白-1(monocyte chemoattractant protein-1,MCP-1)的浓度,并探讨它与小梁切除术预后的关系。方法回顾性病例对照研究。纳入小梁切除术失败的APACG患者19例作为病例组,57例年龄、性别匹配的小梁切除术成功的APACG患者作为对照组。APACG患者小梁切除术术前收集房水,用酶联免疫吸附试验检测两组患者房水中MCP-1浓度。采用单因素以及多因素logistic回归分析小梁切除术失败的危险因素。结果病例组患者房水中MCP-1的浓度为(5688.04±2099.99)ng·L^(-1),对照组为(2077.57±568.44)ng·L^(-1),病例组房水中MCP-1的浓度明显高于对照组,两组相比差异有统计学意义(P<0.001)。logistic回归分析显示,术前房水中MCP-1浓度(OR=1.005;95%CI=1.001~1.008)以及患者小梁切除术后浅前房发生(OR=31.430;95%CI=1.577~57.350)是小梁切除术失败的独立危险因素。结论术后1 a随访时小梁切除手术失败的APACG患者房水中MCP-1的浓度明显高于小梁切除手术成功的患者。APACG患者房水中MCP-1浓度是小梁切除手术失败的独立危险因素。

A Method of Construction for Abundant Semigroups with a CO-Adequate Transversal

In this paper, we first study the structure of quasi-adequate semigroups with a cancellative monoid transversal. By using the above result, we present a method of construction for the abundant semigroups containing a CO-adequate transversal.
