The Present and Future of Clinical Psychology in Private Practice

This article discusses clinical psychologists' current concerns, challenges, and opportunities in private practice. The future of clinicians in independent practice is presented within two paradigms, namely, psychology as a health profession, and psychology as life enhancement. Finally, the author argues that psychotechnology, corporate clinical psychology, and psychology as life enrichment will evolve within the future of clinical psychological independent practice.     

Do bisphosphonates reduce early micromotion and Periprosthetic bone loss in total knee arthroplasty? A review of the evidence

Early micromotion of implant components and periprosthetic bone loss in patients undergoing total knee arthroplasty are thought to contribute to late aseptic loosening. In the pursuit of longer implant survival, the administration of bisphosphonates may be advocated as a means to buffer implants against microinstability and periprosthetic bone loss. A bibliographic search identified one metaanalysis and two randomised controlled trials dealing with this topic. Current evidence supports the hypothesis that the inhibiting effects of bisphosphonates on bone resorption reduce implant micromotion and periprosthetic bone loss at the one-year follow-up. Tested bisphosphonates include clodronate, pamidronate and alendronate. However, a decline in periprosthetic BMD is observed at the three-year follow-up following a sixmonth course of bisphosphonate administration. Length of follow-up in available studies is currently too short to determine whether bisphosphonates increase the longevity of implants. Furthermore, the optimal dose, modality and length of bisphosphonate administration have yet to be determined.     

中国汉坦病毒H82O5株G2糖蛋白基因的克隆及在真核细胞中的瞬时表达

从感染病毒乳鼠脑组织提取总RNA，采用RT－PCR和分子克隆技术将扩增到的G2糖蛋白基因插入含CMV启动子的pcDNA3.1/His质粒载体中，通过脂质体介导转染COS－7细胞，用SDS－PAGE、Western-blot及IFIA方法分别测定表达产物的相对分子量及特异性。结果证明获得正向插入的G2－pcDNA3.1/His重组表达质粒，表达产物的相对分子量为56ku，与理论预期大小一致，并且可与汉坦病毒H8205株的腹水抗体起特异反应。表明构建的G2－pcDNA3.1/His重组质粒所表达的蛋白为中国汉坦病毒株特有，能在哺乳动物细胞中表达并具有抗原性，重组质粒可应用于汉坦病毒的DNA疫苗研究。

74例小儿慢性头痛经辨证治疗,显效80.95%,好转16.67%,无效2.38%。痰浊头痛二陈汤或半夏白术天麻汤加减;肾虚头痛,杞菊地黄汤加减;淤血头痛,补阳还五汤;气血虚头痛八珍汤加减。指出了小儿内伤头痛的病因病机,并指出脑电图,脑阻抗血流图、CT、甲皱微循环可做为此病的诊断及疗效指标。     

循证护理学在实践中的应用

循证护理的核心思想是任何护理决策都要建立在临床客观证据的基础上。护理过程中应进一步开展临床试验研究，以提供更好的护理依据。对临床护理工作中存在的同一问题有不同研究结果的情况，要用系统评价的方法进行分析，得出综合可靠的结论。作举例说明循证护理的实施方法。
