标准大骨瓣减压意义

目的探讨标准大骨瓣在重型颅脑损伤救治中的减压意义,加深临床对标准大骨瓣减压作用的理解。方法结合我院2000年1月-2007年1月46例重型颅脑损伤的患者资料进行回顾性分析。结果本组46例患者均行标准大骨瓣减压,术中全部放置颅内压监测探头,术后持续颅内压监测1周,联用人血清蛋白或血浆、甘露醇、速尿脱水,颅内压一般在15-30 mmHg范围内。术后3d、1周、2周、1个月复查CT。2例发生右额叶脑梗死,1例发生右顶枕叶脑梗死。术后随访6个月至1年,效果良好26例,中残8例,重残6例,植物生存4例,死亡2例。结论标准大骨瓣入路可多途径的达到减压作用,在重型颅脑损仍的救治中有着重要的内、外减压意义。     

非手术治疗自行缓解的小脑扁桃体下疝畸形Ⅰ型伴脊髓空洞症1例报道及文献复习

小脑扁桃体下疝畸形伴脊髓空洞症自发缓解或消失在成年人中极为罕见。该文报道了1例有手术治疗适应证，但未行手术治疗，而临床症状和影像学表现自发好转的病例。通过文献检索，发现了5例未经手术治疗但临床症状有不同程度好转的病例。经分析这些患者的共性，总结出了对于围绝经期女性患者，可以保守治疗，但需要定期随访，若病情恶化再行评估是否需要手术治疗。 [国际神经病学神经外科学杂志, 2023, 50(4): 50-53]

新疆喀什地区农村改水水质及水源卫生防护调查与评价

为了解新疆喀什区农村改水水质及水原防护状况，对该地区改水后的深井水，手压井水与改水前的池塘水水质及水源卫生防护状况进行调查和监测。结果表明，与改水前比较，水质及水源防护卫生状况明显改善，水质合格率分别是：池塘水３．３％，手压井水４０．０％，深水井５１．７％，结果还表明有必要加强对改水水源的卫生防护。

Assessing the factors influencing continuous quality improvement implementation: experience in Korean hospitals.

OBJECTIVE: To assess the extent of continuous quality improvement (CQI) implementation in Korean hospitals and to identify its influencing factors. DESIGN: Cross-sectional study by mailed questionnaire survey. STUDY PARTICIPANTS: One hundred and seventeen staff members with responsibility for CQI at 67 hospitals with > or = 400 beds. MAIN OUTCOME MEASURES: The degree of CQI implementation was measured using the Malcolm Baldrige National Quality Award Criteria (MBNQAC). Factors related to the degree of CQI implementation were the four components of the CQI pyramid, namely the cultural, technical, strategic, and structural attributes of individual hospitals. RESULTS: The average CQI implementation score across the seven dimensions by MBNQAC was 3.34 on a 5-point scale. The highest score was achieved in the dimension of 'customer satisfaction' (3.88), followed by 'information/analysis' (3.59), and 'quality management' (3.35). Regression analysis showed that hospitals which better fulfilled technical requirements, such as improving information systems (P< 0.05), using more scientific CQI tools, and adopting systematic problem-solving approaches (P<0.01), tended to achieve higher degrees of CQI implementation. Although statistically insignificant, positive trends were observed for group/developmental culture and the degree of employee empowerment, and the use of prospective strategy. CONCLUSION: It appears that the most important contributing factors to active CQI implementation in Korean hospitals were the use of scientific skills in decision-making and the adoption of a quality information system capable of producing precise and valid information.     

怎样提高医学生的儿科毕业实习质量

毕业实习是临床医学生大学学习生活的最后阶段 ,是医学生巩固和加强所学理论知识、将其应用于实践及培养独立能力的学习阶段 ,也是从书本知识到临床实践的过渡阶段 ,是为当好一名合格的医生打好基础的关键时期 ,还对下一时期能否接受更高、更深、更新的知识或技能产生直接或潜在的影响[1,2 ] .儿科是临床医学中一门涉及面较广和整体性较强的学科 ,是医学生必读课程和主干课程 ,儿科教研室历来重视医学本科生的毕业实习 ,安排主治医师按照有关规定 ,依据实习大纲认真带教 .现将儿科教研室为提高毕业质量采取的措施总结如下 .1　加强基本功训…     

Significant precision improvement for temperature mapping.

MR temperature measurements are important for applications such as the evaluation of thermal therapies and radiofrequency (RF) coil heating effects. In this work the spherical mean value (SMV) method has been applied to significantly improve the precision of MR temperature mapping in a homogeneous gel phantom. Temperature-increase maps of the phantom were obtained with three-dimensional (3D) MR phase difference mapping after heating with the RF coil. The temperature-increase distribution in most regions in the phantom is a harmonic function with the mean value property. Based on this property, the precision of temperature-increase maps was improved up to sixfold with the SMV method. Comparison of this method with conventional smoothing, further precision improvement, and the in vivo application of the SMV method are discussed.
