摘要：目的:利用三维治疗计划系统(TPS)分析鼻咽癌常规二维(2DRT)、三维适形(3D-CRT)和调强适形放疗(IMRT)三种计划颞叶和靶区的剂量分布,比较鼻咽癌三种放疗计划中颞叶的剂量差别。方法:选择鼻咽癌患者20例,其中T1、T2期10例,T3、T4期10例,采用TPS对每例患者分别设计2DRT、3D-CRT和IMRT三套放疗计划,分析每套计划中颞叶Dmean、Dmax、D1cc、V60和V65及靶区的D mean和D95,比较三套计划中颞叶的剂量差别,以及这种差别的幅度与T分期有无关系。结果:(1)靶区剂量:2DRT、3D-CRT和IMRT三组计划中PGTV nx的D95在T1、T2期分别为6678 cGy、6864 cGy和7044 cGy;在T3、T4期分别为7140 cGy、7336 cGy和7294 cGy。(2)颞叶剂量:2DRT、3D-CRT和IMRT三组计划相比,颞叶受照剂量和体积依次降低(Dmean、Dmax、D1cc、V60和V65),其中所有T分期的D1cc和T3、T4期的Dmax、V60和V65在三组计划间均有统计学差异;所有T分期的D mean和T1、T2期的V60和V65在3D-CRT和IMRT组间无统计学差异,但均明显低于2DRT;T1、T2期的D max在IMRT组明显低于2DRT和3D-CRT组,但后两组间无统计学差异。(3)颞叶V60和V65在2DRT、3D-CRT和IMRT计划中依次减小趋势在T3、T4期比T1、T2期更明显。结论:与2DRT、3D-CRT相比,IMRT能明显降低鼻咽癌颞叶受照剂量和体积,特别是T3、T4期鼻咽癌,颞叶高剂量区受照体积降低更明显;但在一些IMRT技术资源缺乏的地区,NPC放疗可提倡运用3D-CRT技术更好保护颞叶,应尽量减少2DRT技术的应用。

摘要：我国正处在转变经济发展方式的过程之中,如何推动适应经济转型需要的服务业大发展?国内外实践证明,政府财政税收政策的作用不容小视。2012年5月24日由上海金融学院主办、上海金融学院财税与公共管理学院承办的"适应经济转型推动服务业大发展的财税政策高层论坛"适逢其时。来自学术界、实务界的国内外50余位与会嘉宾,围绕推动服务业大发展财税政策的宏观背景分析、我国财税改革实证分析、财税政策设计的基本原则及其政策设计等方面问题,进行了认真而深入的讨论,并提出了许多真知灼见。本刊编辑部以此论坛为契机,期待更多的有识之士为推动我国服务业的大发展献计献策。

摘要：目的：探讨精神科患者家属陪伴幸福感指数。方法：采用自行设计的问卷对60侧精神科患者进行调查。结果：60％的患者认为家属陪伴幸福感高、30％的患者认为有无家属陪伴无区别、10％的患者认为有家属陪伴幸福感低。不同病种对家属陪伴的需求不一致。结论：根据患者的需求，合理安排家属陪伴，以满足患者多元化，多层次的需求。

摘要：Objective: Previous studies did not establish a clear correlation between the presence of endometriosis and the values of body mass index (BMI). Study design: The BMI of 366 women with endometriosis was compared to that of 248 controls undergoing laparoscopy because of benign gynaecological conditions. Significant differences at univariate analyses were confirmed by using Analysis of covariance (ANCOVA) to control for potential confounding variables. Results: BMI was significantly lower in women with endometriosis than in controls (p < 0.001); this difference was confirmed when the analysis was restricted to subjects with normal BMI (18.50-24.99 kg/m2) (p = 0.002). 4.8% of control subjects and no woman with endometriosis were obese. No significant difference was observed in the BMI of women with mild (revised classification of the American Fertility Society, rAFS Ⅰ -Ⅱ ) and severe endometriosis (rAFS Ⅲ -Ⅳ ). Conclusion: Women with endometriosis have lower BMI and are less frequently obese than control subjects. Further studies should investigate the physiopathological basis of decreased BMI in women with endometriosis.

摘要：Objectives: The inlay skin grafting technique proposed by McIndoe is by far the most popular and the safest technique for treatment of vaginal agenesis. The purpose of the current study is to present clinical experiences and long-term results of modified Abbé -McIndoe technique. Study Design: We present the long-term results of 22 patients with a follow-up period ranging between 7 and 14 years. Results: Mean vaginal depth was recorded to be 8 cm and narrowing of the vagina was not noted. Only in two cases was deficient vaginal depth observed which was due to inadequate use of the mould in the postoperative period. Histologic study of the specimens obtained from the neovagina revealed normal vaginal mucosa in all patients. Conclusion: Although numerous methods have been described since the first surgical intervention for the correction of vaginal agenesis, a modified Abbé -McIndoe technique is still the effective and preferred one.

摘要：目的：调查住院精神病患者对护理工作的评价，了解影响精神病患者对护理服务满意度的因素，为医院管理者提供管理依据，进一步提高精神科护理质量。方法：采用随机抽样的方法选取在某医院的住院精神病患者150例，采用自行设计的问卷进行调查。结果：住院精神病患者对护理服务总体及各难度的评价较高；不同病房管理模式（开放病房管理模式、封闭病房管理模式）、不同病种、不同医疗费用支付方式的精神病患者对护理满意度的差异具有显著性。结论：本研究为测定精神病患者对护理服务满意度提供了一个工具。护士在实施护理服务时应充分考虑精神病患者的个体差异，注重提高生活护理服务，满足病人的基本生理需求。
