Assisting students with autism to cooperate with their peers to perform computer mouse collaborative pointing operation on a single display simultaneously

The purpose of this study was to provide students with autism spectrum disorder (ASD) the chance to cooperate with their peers to perform computer mouse collaborative pointing operation. In this study, we adopted the Single Display Groupware (SDG) concept to develop the Multiple Cursor Collaborative Operating Program (MCCOP) software, which allows multiple users to operate a single computer simultaneously without interfering with each other. With the implementation of MCCOP software, users control their own cursors to perform a function in their respective cursor moving areas on a single display. A collaborative pointing test software (CPTS) program was designed in this experiment to evaluate participants’ collaborative pointing performance. This study adopted an ABAB design, and the experimental results show that all participants significantly increased their collaborative pointing performance during the intervention phase, compared to the baseline phase. Practical and developmental implications of the findings are discussed.     

The role of specialist nurses in delivering effective care in a tertiary sarcoma referral service

Musculoskeletal sarcomas are rare cancers with an incidence of less than 1% of all cancers. Management of these tumors requires multidisciplinary care comprising of numerous specialists. Critical decisions following collaborative discussion among treating specialists followed by timely communication and starting prompt treatment are vital in delivering care in such rare sarcomas. While musculoskeletal surgeons, radiologists, and clinical oncologists are well known, the role of specialist nurses has been less described. They form a vital pillar in any tertiary sarcoma service by assisting in collaborative care, having consultations in nurse-led clinics, offering psychological support, imparting details of treatment to patient and helping in palliative care. This narrative review focuses on the role of trained specialist nurses in a tertiary sarcoma service and gives insight into their vital role in delivering timely, coordinated, effective care.     

化瘀补肾方对卵巢切除小鼠骨折愈合的作用

目的观察化瘀补肾方对卵巢切除小鼠骨折愈合的作用。方法 3月龄雌性C57BL/6小鼠48只分为假手术组、模型组和化瘀补肾方组各16只。模型组和化瘀补肾方组小鼠采用双侧卵巢切除术(OVX)建立骨质疏松症模型。术后12周,各组小鼠建立左侧胫骨中段骨折模型。术后给予化瘀补肾方组小鼠化瘀补肾方灌胃,给予假手术组与模型组小鼠等体积生理盐水灌胃,至骨折术后4周取材。检测各组小鼠血清雌二醇水平,采用Micro-CT检测小鼠第4腰椎及左侧胫骨的骨密度,检测左侧胫骨最大应力,对左侧胫骨石蜡切片进行阿尔辛蓝/橙黄G染色,观察骨组织形态学变化。结果 OVX后4周开始,模型组小鼠体重明显升高,并持续高于假手术组(P0.01)。骨折术后4周,模型组小鼠血清雌二醇和第四腰椎骨密度(BMD)明显低于假手术组(P0.01),化瘀补肾方组小鼠血清雌二醇水平和第四腰椎BMD高于模型组(P0.01)。Micro-CT三维重建显示,模型组左侧胫骨仍有明显的骨折线,骨痂生长不明显,化瘀补肾方组骨折线模糊,骨痂形成明显。与假手术组相比,模型组小鼠的BV/TV(P0.01)、Tb.Th(P0.05)和Tb.N(P0.01)均明显降低,Tb.Sp明显升高,化瘀补肾方组小鼠的BV/TV(P0.05)、Tb.Th(P0.05)相较于模型组则显著升高,但Tb.N、Tb.Sp差异无统计学意义。与假手术组比较,模型组小鼠胫骨的最大应力在骨折术后28 d时显著低于假手术组(P0.01),化瘀补肾方组小鼠胫骨的最大应力显著高于模型组(P0.01)。阿尔辛蓝/橙黄G染色显示,假手术组和化瘀补肾方组骨痂组织处于塑形期,可见明显骨小梁结构,而模型组骨痂组织内见大量脂肪组织,骨小梁稀疏。结论化瘀补肾方能有效促进去卵巢小鼠的骨折愈合,改善愈合骨组织的生物力学性能。     

口服或阴道用米索前列醇用于人工流产术前宫口扩张的比较

目的 :比较在人工流产术前阴道或口服用米索前列醇后宫口扩张的临床效果。方法 :将 16 1例行人工流产术的早孕妇女分成 3组。第 1组 5 3例和第 2组 5 7例于术前 1h分别经阴道用米索前列醇和口服米索前列醇各 4 0 0 μg ,第 3组为对照组5 1例 ,术前不用任何药物。结果 :第 1组和第 2组宫口扩张有效率分别是 92 % (49/ 5 3)和 89% (5 1/5 7) ,明显高于对照组 0 (0 / 5 1,P <0 .0 1) ;前 2组术中无需使用局部麻醉 (0 / 5 3和 0 / 5 7) ,而对照组则有 74 % (38/ 5 1)的病人需加用局部麻醉 (P <0 .0 1) ;前 2组术中出血量为 (7±s 4 )mL和 (7± 3)mL ,也少于对照组 (12± 4 )mL ,差异有非常显著意义 (P <0 .0 1)。阴道用米索前列醇组与口服米索前列醇组相比 ,术中扩宫口作用差异无显著意义 (P >0 .0 5 ) ,但口服用药组不良反应多于阴道用药组。结论 :阴道用米索前列醇组、口服米索前列醇组术中扩宫口作用肯定 ,出血量小、不良反应轻 ,两者疗效相似
