恒牙列X线头影测量127项指标正常值研究

目的 分析不同性别、不同年龄段恒牙列X线头影测量各指标正常值的差异,探讨二维头影测量分析的测量误差。方法 收集并筛选恒牙列正常〖HT5”,7”〗牙〖KG-*3〗合〖HT5”〗样本,使用Uceph头影测量软件对每个样本的头颅侧位片进行头影测量分析,囊括58个标志点、127项测量指标。结果 本研究纳入11～30岁的样本共168例,青少年和年轻成人中分别有42.5%、27.6%的头影测量指标存在性别差异（P＜0.05）。头影测量同一指标两次测量的组内相关系数ICC平均值达0.911。结论 本研究建立的X线头影测量正常值可靠性较高,可用于正畸患者的临床诊断、矫治设计和效果评价。男性和女性、青少年和年轻成人头测指标存在一定差异,临床上应依据不同性别、不同年龄段选择相应的参考值。     

The Donor Kidney Biopsy and Its Implications in Predicting Graft Outcomes: A Systematic Review

Despite a growing organ shortage in the United States, many deceased donor kidneys removed for transplantation are discarded. Kidney biopsy findings often play a role in these discards, although it is not clear whether biopsies reliably inform acceptance decisions. Therefore, we carried out a systematic review of the medical literature on the utility of both procurement and implantation biopsies for predicting posttransplant outcomes. Between January 1, 1994 and July 1, 2014, 47 studies were published in the English language literature that examined the association between pretransplant donor biopsy findings from 50 or more donors (with more than half being from deceased donors) and either posttransplant graft failure, delayed graft function, or graft function. In general, study quality was poor. All were retrospective or did not indicate if they were prospective. Results were heterogeneous, with authors as often as not concluding that biopsy results did not predict posttransplant outcomes. The percent glomerular sclerosis was most often examined, and failed to predict graft failure in 7 of 14 studies. Of 15 semiquantitative scoring systems proposed, none consistently predicted posttransplant outcomes across studies. Routine use of biopsies to help determine whether or not to transplant a kidney should be reexamined.
