左炔诺孕酮宫内缓释系统临床应用研究

左炔诺孕酮宫内缓释系统（LNG-IUS）是一种安全、高效的宫内节育器（IUD），其通过每天释放小剂量的左炔诺孕酮至宫腔实现孕激素的非全身给药，从而开辟了在非避孕领域的许多新的应用。现就其在治疗月经过多、子宫内膜异位症和腺肌症、激素替代治疗期间的子宫内膜保护等方面进行综述。     

坐骨棘筋膜固定术的临床解剖学研究

Objective The study was to explore the safety, firmness and convenience of the fascia around the ischial spine as a new fixation site for the vaginal fornix. Methods Between June 2007 and January 2008, detailed dissections and related measurements of the regions around the ischial spine were performed on 10 Chinese female cadavers (3 unembalmed and 7 embalmed cadavers). At the same time, the sacrospinous ligament,the fascia on the ischial spine, the iliococcygeus fascia as well as the vaginal fornix were exposed and the pull-out strength sequentially tested using a digital push-pull force gauge. Results The fascia on the ischial spine was firm and strong, with a thickness of 3 about mm. No major vessels or nerves were observed on the ischial spine. The greatest pullout strengths of the sacrospinous ligament,the fascia on the ischial spine, the iliococcygeus fascia as well as the vaginal fornix were (102±26),(64±15),(33±8)and(32±6)N, respectively. Conclusion The fascia at 1 cm from anterior lateral ischial spine, free of major vessels and nerves, is safe and strong and could be used as a new site for suspension in vaginal prolapse.

目的　探讨三维适形低分割放射治疗老年非小细胞肺癌的疗效。方法　 4 5例患者均采用低分割治疗 ,处方剂量为 4～ 5Gy,隔日 1次 ,总量 4 8～ 5 5Gy。结果　CR 2 3例 ( 5 1.1% ) ,PR 15例( 33.3% ) ,NC 5例 ( 11.1% ) ,PD 2例 ( 4 .4 % ) ,RR 38例 ( 84 .4 % )。 1、2、3年生存率分别为 6 6 .7%、4 8.9%、39.1%。结论　三维适形放射治疗对于老年非小细胞肺癌是一种反应较小 ,痛苦较轻 ,安全有效的治疗措施     

鼻声反射应用于鼻塞患者鼻通气功能检查的评价

目的 :评估鼻声反射 (AR)在鼻塞患者鼻通气检查中的应用价值 ,并探讨其参数选择。方法 :对 36例因鼻病引起鼻塞的患者 (鼻病组 )及 2 0例无鼻病健康志愿者 (对照组 )进行AR测试 ,测算鼻腔平均截面积 (MNCA)、最小截面积 (MCA)、鼻腔容积 (NV)和鼻阻力 (NR) ,并进行统计学分析。结果 :对照组中 ,MNCA、MCA、NV、NR性别差异均无统计学意义 (P >0 .0 5 ) ,除NV(P <0 .0 5 )外侧别差异亦无统计学意义 (P >0 .0 5 ) ;鼻病组中鼻塞侧与非鼻塞侧各参数间差异无统计学意义 (P>0 .0 5 ) ;鼻病组中鼻塞侧与对照组比较 ,其中MCA和NR差异有统计学意义 (分别P <0 .0 1和P <0 .0 5 ) ;鼻病组中非鼻塞侧加对照组与鼻病组中鼻塞侧比较 ,其中MCA和NR差异有统计学意义 (分别P <0 .0 1和P <0 .0 5 )。结论 :AR对鼻通气状况有较客观的反映 ,其中MCA和NR对鼻塞状况的反映与患者的主观感受较为一致 ,可作为反映鼻通气状况的敏感指标。     

795例肠外营养支持的回顾性分析

目的:对795例患者的肠外营养支持进行回顾性分析.方法:对行肠外营养支持的399例患者进行治疗前后淋巴细胞计数、血浆白蛋白和血浆锌离子浓度等营养学指标的比较,并选择行肠外营养的患者198例与行单一静脉营养的患者198例进行营养学指标的比较,同时比较不良反应和依从性.另选择25例有单一静脉营养史患者25例,分为足量组13例和低氮组12例,分别按照1.0～1.5和0.6 g·kg-1·d-1逐渐在3 d内递增到1.0～1.5 g·kg-1·d-1给予氨基酸,其余营养支持相同, 进行营养学指标的比较.结果:与治疗前比较,行肠外营养支持后患者的白蛋白、淋巴细胞计数、锌离子浓度等均显著增加(P<0.05).与单一静脉营养相比较,行肠外营养患者的白蛋白、淋巴细胞计数、锌离子浓度等也均显著增加(P<0.05),同时不良反应和依从性较好.足量组与低氮组比较,白蛋白值显著增加,而淋巴细胞计数、锌离子浓度无显著性差异.结论:肠外营养支持可以显著改善营养不良.     

钬激光对复杂输尿管结石的诊疗价值 (附56例报告)

目的:探讨钬激光治疗复杂性输尿管结石有效性及安全性。方法:回顾性分析2003年12月～2005年12月收治的经输尿管镜钬激光治疗复杂性输尿管结石56例患者的临床资料。56例患者均有不同程度肾积水。12例并发结石远端输尿管狭窄,27例并发单纯息肉,9例并发息肉形成并包裹结石,8例并发结石嵌顿、与输尿管壁紧密粘连,24例有接受ESWL治疗史,5例曾行输尿管切开取石术。双侧输尿管结石伴肾功能减退6例。结果:56例中,53例单次手术碎石成功,单次手术结石粉碎率达94.6%(53/56),1例在钬激光碎石过程中结石移位于肾盏,术后再行ESWL治疗,1例进镜时输尿管穿孔,1例巨大结石行钬激光碎石失败改为开放手术。结论:输尿管镜钬激光碎石术治疗复杂性输尿管结石安全、有效、微创,可作为治疗复杂性输尿管的首选方法。
