Neural Regeneration Research 2016年第1期11卷 66-68页

作者： Laura A.Smith callahan The Vivian L.Smith Department of Neurosurgery & Center for Stem Cell and Regenerative Medicine University of Texas Health Science Center at Houston

Traumatic injuries to the central nervous system,such as traumatic brain injury,spinal cord injury and stroke,have a high prevalence,enormous financial costs and lack clinical treatments that restore neurological function（Ma et al.,2014）These injuries trigger a series of secondary biochemical and cellular responses that ultimately lead to cellular death and themaintenance of an unsupportive extracellular matrix （ECM） for tissue regeneration （Silva et al., 2014）. Artificial ECM or scaf- folds represent a way to alter this unsupportive environment to improve the efficacy of stem cell therapies and enhance neural tissue regeneration （Figure 1）.

BACKGROUND The national rates of readmission and reoperation after open reduction internal fixation(ORIF)of midshaft clavicle fractures in adolescents is *** To determine rates of and risk factors for readmission and reoperation after ORIF of midshaft clavicle fractures in *** This retrospective study utilized data from the Healthcare Cost and Utilization Project State Inpatient Database for California and Florida and included 11728 patients 10–18 years of age that underwent ORIF of midshaft clavicle fracture between 2005 and *** within ninety days,reoperations within two years,and differences in patient demographic factors were determined through descriptive,univariate,and multivariate *** In total,3.29%(n=11)of patients were readmitted within 90 d to a hospital at an average of 18.91±18 d after discharge,while 15.87%(n=53)of patients underwent a reoperation within two years at an average of 209.53±151 d since the index *** most common reason for readmission was a postoperative infection(n<10).Reasons for reoperation included implant removal(n=49)at an average time of 202.39±138 d after surgery,and revision ORIF(n<10)with an average time of 297±289 d after index *** odds of reoperation were higher for females(P<0.01)and outpatients(P<0.01),while the odds of reoperation were lower for patients who underwent surgery in California(P=0.02).CONCLUSION There is a low rate of readmission and a high rate of reoperation after ORIF for midshaft clavicle fractures in *** are significant differences for reoperation based on patient sex,location,and hospital type.

本项研究讨论了以靴袢程序为基础的推断油气储量估计的置信区间。推断储量就是希望添加到以前在常规油气田中发现的探明储量中的那些储量。在美国地质调查局(USGS)1995年美国陆上和海上全国油气评估中，推断储量约占总石油储量的65％，占总天然气储量的34％。用1995年评估使用的相同计算方法输入最近的数据，估计了1997年以前发现的美国本土48州陆上和海上区域80年(1997-2076年)的推断储量，总共为397亿桶油和293万亿立方英尺气。根据靴袢方法导出的石油储量估计的90％置信区间为224．695亿桶。推断天然气储量估计的90％置信区间为217．413万亿立方英尺。90％置信区间描述了估计的不确定性。

本项研究的主要目的是：（1）研究通过历史生产数据揭示的非常规天然气资源建立区域趋势的经验方法；（2）确定是否需将更多的区域趋势知识加入到一套以前建立的局部非参数资源预测算法中，以便对评估成果产生影响。把三种不同趋势方法应用于来自密歇根盆地泥盆系Antrim页岩气区的公开有效生产数据（井的最终采收率（EUR）共计80英亩单元）。这种方案可用于鉴别页岩气区内网格EUR值的东南．西北趋势。在一般意义上，这与该州的主要裂缝和构造方向一致。然而，资源预测算法中包括的这种趋势并不能改善最终结果。进一步分析结果表明，网格EUR值之间存在有可能抑制区域趋势作用的群集。虽然相关地质文献中提供了一些可能的解释，但出现这种群集的成因并不能完全理解，且有时会导致获得不可预测的结果。通过应用适当数据，更好地理解这种群集现象可以获得控制Antrim页岩气产量的有关因素及其相互作用的重要信息。进而，有助于为更好地评估Antrim页岩气区或其它页岩气区的资源而建立一种更普遍的方案。
