Retinopathy of prematurity (ROP) has become the leading blinding eye disease in children worldwide. In recent years, the recognition and treatment of acute stage lesions have achieved remarkable results. Fundus lesions could spontaneously regress in most of children with ROP, while the understanding of the law of spontaneous regression is still very limited. Although the fundus morphology is significantly improved after spontaneous regression, the long-term prognosis of visual function is not optimistic. The introduction of new technologies such as fundus fluorescence angiography and optical coherence tomography and angiography will help further understanding the nature of the spontaneous regression. To increase the study about spontaneous regression of ROP, which has significance for rationally arranging an economical and efficient screening time, formulating a scientific and individual treatment and follow-up plan, and improving the prognosis of visual function.
目的 研究巩膜外垫压手术联合视网膜激光光凝对硅油眼视网膜脱离的治疗效果。 方法 回顾性分析2009年1月－2012年1月，用巩膜外垫压联合视网膜光凝手术治疗36例硅油眼视网膜脱离的视网膜复位效果。 结果 全部患者均顺利完成巩膜外垫压手术及随后的视网膜激光光凝，行巩膜外放液5只眼，手术中未发生视网膜嵌顿、眼内出血和眼压显著升高等并发症；手术后1周视网膜复位21只眼（58.33%），剩下15只眼1个月后复位7只眼（19.44%），视网膜脱离总复位率为28只眼（77.77%）；未复位8只眼（22.23%），改用玻璃体切割手术方式，视网膜成功复位；6个月后取出硅油，随访6个月视网膜无脱离或者脱离范围增加；手术后眼压≥30 mm Hg （1 mm Hg=0.133 kPa）3只眼，≥20 mm Hg 7只眼，对症治疗1周后眼压均恢复到正常范围。 结论 巩膜外垫压联合视网膜激光光凝治疗硅油眼视网膜脱离，手术简单，复位率高，可为硅油眼视网膜脱离首选手术方式，对于巩膜外垫压手术失败和复杂的硅油眼视网膜脱离，应当选择玻璃体切割手术方式。
ObjectiveTo analyze the causes and characteristics of massive hemorrhage secondary to percutaneous nephrolithotomy (PCNL) and assess the value of superselective renal artery embolization in the management of this condition. MethodsThe imaging data and prognosis of 28 patients who developed repeated massive hemorrhage secondary to PCNL and underwent superselective renal artery embolization between April 2005 and June 2013 were reviewed. ResultsFollowing superselective renal artery embolization, hemorrhage was effectively controlled in all the 28 patients. Follow-up lasted from 6 to 62 months, averaging 41.6 months. No hematuria or other complications occurred during the follow-up period. ConclusionSuperselective renal artery embolization is safe and effective in managing massive hemorrhage secondary to PCNL, and it may be used as a preferred treatment for patients who are refractory to expectant treatments.
目的 评价UF-1000i全自动尿沉渣分析仪中沉渣定量模块中白细胞和细菌参数阈值在排除尿路感染的应用价值。 方法 选取2 580份清洁中段尿液, 同时进行细菌培养菌落计数和UF-1000i尿沉渣白细胞和细菌定量分析，建立ROC曲线确定白细胞参数与细菌参数阈值。 结果 以尿定量培养菌落计数G?菌≥105 cfu/mL，G+菌≥104 cfu/mL为阳性参考标准，当白细胞沉渣定量为100/μL时，UF-1000i尿沉渣分析仪检测灵敏度为64%，特异度为75%，阴性预测值为96%；当UF-1000i细菌计量为901/μL时，检测灵敏度为68.3%，特异度为92.8%，阴性预测值为97%。 结论 UF-1000i检测新鲜尿标本白细胞的测定值lt;100/μL，细菌值lt;901/μL时能够作为临床早期排除尿路感染的依据之一。
目的 探讨胰十二指肠切除术中引流管的放置与术后管理的方法。方法回顾性分析88例胰十二指肠切除术后管理经验。结果 术后腹腔并发症的发生率为10.2%(9/88)，胃排空障碍发生率为3.4(3/88)%，其中保留幽门胰十二指肠切除术后胃排空障碍发生率为5.5%(3/55)。结论 胰十二指肠切除术后腹腔引流是预防术后并发症的重要方法，术中合理放置引流管，术后加强腹腔引流的管理，能减少术后并发症的发生。
