64层螺旋CT使用低剂量对比剂在CTA中对脑动脉瘤的诊断价值

目的 研究64层螺旋CT使用低剂量对比剂联合生理盐水在CTA中对脑动脉瘤的应用价值.方法 对临床疑有脑动脉瘤51例患者分为三组:甲组90ml对比剂不用生理盐水冲洗；乙组、丙组分别使用70ml、50ml对比剂之后用相同流速生理盐水40ml冲洗.对比剂流速为5.0ml/s.当颈内静脉显影的一刹那开始扫描.利用工作站软件进行图像处理,评估三组血管图像质量及动脉瘤显示情况.结果 三组病例动脉瘤的灵敏度、特异性在统计学上没有明显差异,甲组动静脉均显示很好,CT值较高.丙组动脉显示良好,静脉少,污染轻,血管CT值略低.乙组居于二者之间.结论 使用低剂量对比剂50ml+40ml生理盐水以5.0ml/s流率注射,不仅可以得到理想的图像,还是一种安全、快速、经济的检查方法.     

碱性成纤维细胞生长因子对皮肤软组织撕脱伤创面修复效果及肝肾功能影响

目的:观察碱性成纤维细胞生长因子(basic fibroblastic growth factor,bFGF)与常规换药对皮肤软组织撕脱伤创面的修复效果以及肝肾功能的影响.方法:临床纳入皮肤软组织撕脱伤患者70例,根据临床治疗方案的不同分为研究组与对照组,研究组给予bFGF药液喷雾剂喷洒后纱布覆盖,对照给予生理盐水清理常规换药.观察两组患者的创面愈合率、创面炎症反应等,同时观察治疗前后两组患者肝肾功能的变化.结果:研究组术后3、5、7d创面愈合率分别为(29.1±12.9)％、(61.4±18.7)％、(96.3±7.0)％,对照组分别为(19.9±12.1)％、(41.2±17.5)％、(71.6±22.1)％,差异均有统计学意义(P＜0.05);研究组治疗后3、5、7d创面炎症评分分别为(1.62±0.34)、(1.24±0.30)、(0.99±0.29)分,对照组分别为(1.86±0.48)、(1.82±0.45)、(1.60±0.39)分,差异均有统计学意义(P＜0.05);治疗后,两组患者肝肾功能指标未见异常,差异无统计学意义(P＞0.05).结论:bFGF治疗皮肤软组织撕脱伤具有较好的临床效果,能够促进创面的修复,减轻炎症反应,且安全性较高,值得推广.     

The development and validation of methods for evaluating the immune system in preweaning piglets

The preweaning piglet has been found to be a valuable research model for testing ingredients used in infant formula. As part of the safety assessment, the neonates' immune system is an important component that has to be evaluated. In this study three concurrent strategies were developed to assess immune system status. The methods included (1) immunophenotying to assess circulating innate immune cell populations, (2) monitoring of circulating cytokines, particularly in response to a positive control agent, and (3) monitoring of localized gastrointestinal tissue cytokines using immunohistochemistry (IHC), particularly in response to a positive control agent. All assays were validated using white papers and regulatory guidance within a GLP environment. To validate the assays precision, accuracy and sample stability were evaluated as needed using a fit for purpose approach. In addition animals were treated with proinflammtory substances to detect a positive versus negative signal. In conclusion, these three methods were confirmed to be robust assays to evaluate the immune system and GIT-specific immune responses of preweaning piglets.     

盐城地区7家医院抗肿瘤中成药使用情况调查及 影响因素分析*

目的：对盐城地区7家医院抗肿瘤中成药使用情况进行调查,以促进抗肿瘤中成药的合理使用。方法：随机抽取7家医院2017年7月至2018年6月间收治的肿瘤患者病历共1933份,对其性别、年龄、支付方式及抗肿瘤中成药的名称、剂型、用法用量、金额等进行统计,分析抗肿瘤中成药使用的影响因素。结果与结论：抽取三级综合医院病历470份、三级专科医院451份、二级综合医院1012份,上述医院抗肿瘤中成药使用率分别为24.9%、30.2%、21.4%,单个病例平均抗肿瘤中成药使用种数分别为0.48（0.48~0.60）、0.48（0.48~0.60）、0.48（0.48~0.48）种。各级医院中艾迪注射液使用率均较高。患者性别、年龄、是否手术对各级医院抗肿瘤中成药使用均无影响;而患者是否化疗、支付方式对抗肿瘤中成药使用存在影响。抗肿瘤中成药不合理使用问题主要表现在用法用量、中成药与西药联用、溶媒等方面不适宜。     

Activity limitations and participation restrictions experienced by people with stroke in Musanze district in Rwanda

BackgroundStroke is a major cause of long-term disability. Information regarding the limitations in activity and participation experienced by patients with stroke in a specific setting such as Musanze district in Rwanda would assist to develop the rehabilitation programmes that would take into consideration the functional challenges experienced post stroke.ObjectiveTo explore the activity limitations and participation restrictions experienced by people with stroke in Musanze district in Rwanda.MethodsA qualitative phenomenological approach using in-depth face-to-face interviews with 10 participants was employed to gather the data that was analyzed using a qualitative thematic approach.ResultsThe themes that arose as activity limitations included limitations in walking, self care, and domestic life activities. The themes related to participation restrictions as expressed by the participants were inability to return to previous occupation, decreased social interactions and inability to participate in religious activities.ConclusionThe current study findings highlight the need for interventions to improve the functional status of stroke survivors.
