上、下方自体角膜缘干细胞移植治疗翼状胬肉的临床对比

目的探讨上、下方自体角膜缘干细胞移植治疗翼状胬肉的临床对比及意义。方法随机抽取120例翼状胬肉病人，分上方和下方自体角膜缘干细胞移植两组各60例，观察其疗效、复发及角膜刺激症状等。结果上、下方两组治愈率和复发率均无差异，但术中操作和术后患者的感觉及以后做内眼手术位置的选择下方组优于上方组。结论取上、下方自体角膜缘干细胞移植治疗翼状胬肉均达到了治愈率高、复发率低的效果，但取下方组更具有术中操作方便、术中舒适、便于以后做内眼手术等优点。     

Concordant Atrioventricular Connection to L-Looped Ventricles with the Left Ventricle on Top of the Right Ventricle in Situs Solitus: A Case Report with 3D Modelling and Printing

We report the case of a rare complex cardiac anomaly involving situs solitus, concordant atrioventricular connection with left-hand ventricular topology, and L-looped ventricles. The ventricles had a superior-inferior relationship with an inferiorly located right ventricle, which had a double outlet with far posteriorly located great arteries. The left atrium was elongated, with juxta-positioned atrial appendages on the right side. The 3D-printed model using a computed tomography scan taken on the fourth day of birth demonstrated the anatomy clearly and helped us decide on the surgical management.
