【摘要】 目的 研究Monaco治疗计划系统中不同参数设置对容积旋转调强放射治疗(VMAT)计划质量的影响，得出更合理的治疗计划参数设置以提高VMAT治疗质量。 方法 2010年1-5月间治疗3例患者，为食管癌、宫颈癌和鼻咽癌各1例，分别设置不同的计划参数进行容积旋转调强计划优化，通过多种评估指标比较各VMAT计划质量的差异，得出临床所需的MSC、MSS、SSF、Sm、MMS和MDR共6个治疗计划参数对VMAT治疗质量的影响。 结果 MSC、MSS和SSF的3个参数对VMAT治疗质量不产生影响，有影响的Sm、MMS和MDR参数中，随着Sm和MMS值的增大，VMAT计划的剂量分布逐渐变差，但控制点数、机器跳数和照射时间均逐渐减小；随着MDR值增大，VMAT治疗的剂量分布先逐渐变差后不变，控制点数和机器跳数均是先增大后不变，而照射时间是先减小后不变。 结论 Sm、MMS和MDR 3个参数对VMAT计划质量有较大影响，对不同的患者，设置合适的Sm、MMS和MDR值对提高计划质量非常重要。【Abstract】 Objective To investigate the impacts of parameter settings on the quality of plans for the volumetric modulated arc therapy (VMAT) with Monaco treatment planning system. Methods Three patients who underwent VMAT from January to May 2010 were selected. The planning optimizations were processed by setting different planning parameters, including MSC, MSS, SSF, Sm, MMS and MDR, respectively. Then the quality of each plan with a certain set of parameters was evaluated by various evaluation indexes. The differences of quality among different plans were analyzed by comparing these indexes. Results There was no influence on the quality of VMAT planning for the parameter MSC, MSS and SSF to be set with different values. However, the other three parameters, MSC, MSS and SSF , affected the quality of VMAT planning with different values. Along with the aggrandizement of Sm and MMS value, the dose distribution of VMAT plans gradually became bad, while the number of control points, machine monitor units and irradiation time were gradually reduced. And along with the aggrandizement of MDR value, the dose distribution of VMAT plans became bad gradually until a constant state was reached, and both the number of control points and machine monitor units increased at first and then kept constant, while irradiation time decreased at first and then kept constant. Conclusion The selections of parameter Sm, MMS and MDR impact the quality of VMAT planning greatly. It is very important to set the suitable value of Sm, MMS and MDR to get the best planning quality for patients with different complexity.
目的 提出双心室起搏室间间期（VV）优化新算法，并验证其合理性。 方法 选择2009年6月－2012年12月间在成都市第三人民医院心内科住院的慢性心力衰竭并接受双心室起搏是心脏再同步化治疗的患者41例，根据心脏电－机械耦联的原理，将体表心电图和超声指标的数量关系用新公式来表述，通过前瞻性自身对照研究来比较新算法与传统方法的差异。 结果 41例患者均分别采用新算法、传统超声法及腔内心电图法进行VV优化，测主动脉血流速度时间积分（AVTI）并统计耗时。经方差分析显示新算法的AVTI[（22.32 ± 3.48） cm]优于传统腔内心电图法的AVTI[（19.22 ± 3.07）cm]，组间差异有统计学意义（P＜0.05）；而新算法的耗时[（18.80 ± 3.30）min]较传统超声法的耗时[（203.81 ± 20.12）min]明显减少，组间差异有统计学意义（P＜0.01）。 结论 新算法用于双心室起搏是心脏再同步化治疗的VV优化准确、快速，具有合理性及临床推广价值。
目的 进行护理服务满意度调查，比较和评价开展优质护理服务的效果。 方法 对2009年3月－9月和2010年3月－9月眼科住院患者采用问卷调查方式，了解开展优质护理服务前后患者对护理服务的满意度，并分析相关影响因素。 结果 开展优质护理服务后患者满意度提高，与未开展前相比差异有统计学意义（P＜0.05）。 结论 开展优质护理服务，夯实基础护理，强化和改善护理人员的护理服务意识、服务态度，对提高护理质量及患者满意度有重要意义。
【摘要】 目的 探讨如何通过流程优化应对体检高峰期。 方法 通过体检高峰期流程优化前后（2008年与2010年）的管理成效对比，评估高峰期流程控制的有效性。 结果 体检高峰期流程优化后，平均候检人数由8人下降至3人、平均侯检时间由11.9 min下降至4.2 min，平均体检时间由175 min下降至130 min。体检者对体检环境、服务态度和服务质量的满意度均高于优化前，差异有统计学意义（Plt;0.05）。 结论 通过流程优化与控制有效地缓解了高峰期体检人员等候时间过长现象，极大地提高了体检者满意度，保障了健康体检工作质量。【Abstract】 Objective To explore how to cope with the peak flow of physical examination through the process optimization. Methods Evaluate the utility of the process control at physical examination peak flow, by contrasting the management effect before and after the physical examination peak flow optimization (2008 and 2010).

Objective To refine the technique of portal inflow occlusion and parenchymal transection for laparoscopic hepatectomy in the porcine model. Methods Ten pigs were used. The portal inflow complete or selective occlusion was carried out with portal triad clamping or dissection and division of the left portal pedicle. The sequential laparoscopic local hepatectomy, left lateral lobectomy, and left medial lobectomy were performed without portal inflow occlusion. Parenchymal transection was performed with harmonic scalpel, LigaSure, microwave dissector, bipolar electrocautery, surgical clips, and endoscopic stapler. The efficacy and safety of different techniques in laparoscopic parenchymal transection of the liver were compared. Results The ischemic liver was darken with complete or selective portal triad clamping. The ischemic demarcation line between left and right lobe was obvious with the dissection and division of the left portal pedicle. There was an applicable scope of each hepatic parenchymal transection apparatus. The optimal combination of different techniques could increase efficacy and reduce hemorrhage in laparoscopic parenchymal transection of the liver. Conclusion Technical refinements of portal inflow occlusion and parenchymal transection in porcine models could provide evidences to clinical appliance of laparoscopic anatomic major hepatectomy.
