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 研究鞏膜外墊壓手術聯合視網膜激光光凝對硅油眼視網膜脫離的治療效果。 方法 回顧性分析2009年1月－2012年1月，用鞏膜外墊壓聯合視網膜光凝手術治療36例硅油眼視網膜脫離的視網膜復位效果。 結果 全部患者均順利完成鞏膜外墊壓手術及隨后的視網膜激光光凝，行鞏膜外放液5只眼，手術中未發生視網膜嵌頓、眼內出血和眼壓顯著升高等并發癥；手術后1周視網膜復位21只眼（58.33%），剩下15只眼1個月后復位7只眼（19.44%），視網膜脫離總復位率為28只眼（77.77%）；未復位8只眼（22.23%），改用玻璃體切割手術方式，視網膜成功復位；6個月后取出硅油，隨訪6個月視網膜無脫離或者脫離范圍增加；手術后眼壓≥30 mm Hg （1 mm Hg=0.133 kPa）3只眼，≥20 mm Hg 7只眼，對癥治療1周后眼壓均恢復到正常范圍。 結論 鞏膜外墊壓聯合視網膜激光光凝治療硅油眼視網膜脫離，手術簡單，復位率高，可為硅油眼視網膜脫離首選手術方式，對于鞏膜外墊壓手術失敗和復雜的硅油眼視網膜脫離，應當選擇玻璃體切割手術方式。
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 探討胰十二指腸切除術中引流管的放置與術后管理的方法。方法回顧性分析88例胰十二指腸切除術后管理經驗。結果 術后腹腔并發癥的發生率為10.2%(9/88)，胃排空障礙發生率為3.4(3/88)%，其中保留幽門胰十二指腸切除術后胃排空障礙發生率為5.5%(3/55)。結論 胰十二指腸切除術后腹腔引流是預防術后并發癥的重要方法，術中合理放置引流管，術后加強腹腔引流的管理，能減少術后并發癥的發生。
目的 評價UF-1000i全自動尿沉渣分析儀中沉渣定量模塊中白細胞和細菌參數閾值在排除尿路感染的應用價值。 方法 選取2 580份清潔中段尿液, 同時進行細菌培養菌落計數和UF-1000i尿沉渣白細胞和細菌定量分析，建立ROC曲線確定白細胞參數與細菌參數閾值。 結果 以尿定量培養菌落計數G?菌≥105 cfu/mL，G+菌≥104 cfu/mL為陽性參考標準，當白細胞沉渣定量為100/μL時，UF-1000i尿沉渣分析儀檢測靈敏度為64%，特異度為75%，陰性預測值為96%；當UF-1000i細菌計量為901/μL時，檢測靈敏度為68.3%，特異度為92.8%，陰性預測值為97%。 結論 UF-1000i檢測新鮮尿標本白細胞的測定值lt;100/μL，細菌值lt;901/μL時能夠作為臨床早期排除尿路感染的依據之一。
