Plant pest resistance includes antixenosis, antibiosis, and tolerance. Current popular methods for the genetic improvement of crop pest resistance are traditional breeding method, transgenic breeding, and molecular mark-assisted breeding. This paper introduced major mechanisms and genetic bases of plant pest resistance, ＂and reviewed research progress of domestic and international genetic improvement of plant pest resistance, analyzed the problems and its de- velopment prospects.展开更多
目的探讨尿管腹部外固定法在前列腺绿激光汽化术(greenlight photoselective vaporization of the prostate,PVP)后患者的应用效果。方法采用目的抽样法,选取行PVP患者172例,对照组83例,观察组89例。对照组术后尿管给予常规大腿外侧上1/...目的探讨尿管腹部外固定法在前列腺绿激光汽化术(greenlight photoselective vaporization of the prostate,PVP)后患者的应用效果。方法采用目的抽样法,选取行PVP患者172例,对照组83例,观察组89例。对照组术后尿管给予常规大腿外侧上1/3外固定法,观察组术后尿管采用腹部外固定法。比较2组活动后尿液颜色改变的发生率、留置尿管期间的满意度及尿管外固定装置的牢固性。结果观察组活动后尿液颜色变红改变的发生率明显低于对照组,观察组患者留置尿管期间在舒适度、方便度、保护隐私方面的满意度及满意度总分均高于对照组,观察组尿管外固定装置的牢固性优于对照组,差异均有统计学意义(P<0.05)。结论PVP术后尿管固定于腹部可减少患者活动后出血的发生率,促进康复,提高留置尿管期间的满意度,值得临床推广。展开更多
