改良Brisson术与传统手术对隐匿性阴茎患儿阴茎指数的影响

目的探究改良Brisson术与传统手术对隐匿性阴茎患儿阴茎指数的影响,以供临床参考。方法238例隐匿性阴茎患儿分为观察组120例和对照组118例,分别接受改良Brisson术治疗和传统手术治疗,比较2组围手术期指标、术后并发症情况。术后随访半年,分别从阴茎增加长度、阴茎外观、术后皮肤外观3个方面评估患儿阴茎指数,调查患者对手术的满意度。结果观察组手术时间为(42.36±2.26)min、术中出血量为(8.41±1.36)mL,均低于对照组,差异有统计学意义(P<0.05);观察组术后并发症总发生率(3.33%)与对照组(7.63%)差异无统计学意义(χ^(2)=2.124,P=0.145)。术后半年,观察组的阴茎指数总评分及各方面评分均高于对照组,差异有统计学意义(P<0.05);观察组手术总满意度(90.83%)高于对照组(80.51%),差异有统计学意义(χ^(2)=5.180,P=0.023)。结论与传统术式相比,改良Brisson术有助于缩短手术时间,降低术中出血量及术后并发症发生率,改善患儿术后的阴茎指数。

Spin Wave Resonance in Fe/Cu Compositionally Modulated Films

Fe/Cu compositionally modulated films made by rf sputtering were investigated with ferromagnetic resonance.Spin wave resonances related to interlayer exchange coupling were observed and the phase change of the spin wave was shared by both the Fe and Cu sublayers.The effective spin wave dispersion coefficient was found to increase with increasing thickness of Cu sublayers.
