新生儿缺氧缺血性脑病心肌酶谱测定的临床意义

目的：观察新生儿缺氧缺血性脑病（ＨＩＥ）心肌酶活性化及心脏受损的情况,方法：采用连续监测法等方法检测了１１０例新生儿ＨＩＥ与４５例正常新生儿脐血心肌酶谱测定值比较。结果：血清心肌酶谱ＨＩＥ新生儿组明显高于新生儿正常对照组（Ｐ〈０．０１）,而重度ＨＩＥ组显高于轻、中度ＨＩＥ组（Ｐ〈０．０１）。结论：新生儿ＨＩＥ做心肌产谱测定是诊断其心肌损害、损害程度和估计预后的临床指标之一,有助于临床早期预测新生儿ＨＩＥ心肌损害有给予早期治疗。     

To Stay or Not to Stay: Issues in Rural Primary Care Physician Retention in Eastern Kentucky

An important aspect of primary care physician availability is the retention of physicians once they have located. While retention has been under-researched compared to recruitment, it is especially important in rural areas where physician shortages already exist. This study reports the results of a retention survey completed by 132 primary care physicians in rural eastern Kentucky. The survey sets up an objective, hypothetical retention scenario and asks physicians to respond to structured questions and to an open-ended question about factors not appearing in the survey. In response to the structured portion of the survey, physicians indicate that relief coverage is the most important factor in rural physician retention. A content analysis of 75 open-ended responses reveals that besides the other factors in the survey, "sociocultural integration" is the pre-eminent retention issue for rural practitioners. This article concludes that the role of the local rural community may be more important in retention than in recruitment. Finally, it is suggested that additional in-depth qualitative research be conducted within the local contexts to enhance the understanding of rural physician retention processes.
