利培酮和齐拉西酮对精神分裂症患者血浆细胞因子的影响

目的:研究抗精神病药对精神分裂症患者细胞因子的影响。方法:符合ICD-10精神分裂症诊断的60名患者,随机分为利培酮组(给予利培酮治疗)和齐拉西酮组(给于齐拉西酮治疗),并以健康对照组比较,对患者在治疗前及治疗8周后测量血浆IL-2、IL-6及TNF-α水平,并对患者进行PANSS量表评定。结果:两组患者治疗前后血浆IL-2、IL-6及TNF-α水平与对照组比较,差异有统计学意义(P0.05)。两组患者治疗后血浆IL-2、IL-6及TNF-α水平较治疗前降低,差异有统计学意义(P0.05)。治疗前IL-2水平与PANSS量表阳性症状评分呈正相关(r=0.54,P0.05)治疗后TNF-α与阴性症状分呈显著正相关(r=0.41,P0.05)。结论:精神分裂症患者存在免疫功能异常,利培酮和齐拉西酮可以降低精神分裂症患者细胞因子水平。细胞因子水平与精神病理存在一定相关性。     

The role of geriatric palliative care in hospitalized older adults

ABSTRACT

Take-Away Points:

1. Geriatric palliative care requires integrating the disciplines of hospital medicine and palliative care in pursuit of delivering comprehensive, whole-person care to aging patients with serious illnesses.

2. Older adults have unique palliative care needs compared to the general population, different prevalence and intensity of symptoms, more frequent neuropsychiatric challenges, increased social needs, distinct spiritual, religious, and cultural considerations, and complex medicolegal and ethical issues.

3. Hospital-based palliative care interdisciplinary teams can take many forms and provide high-quality, goal-concordant care to older adults and their families.     

一次性湿热交换器在新生儿机械通气长途转运中应用的效果分析

目的探讨研究一次性湿热交换器在新生儿机械通气长途转运中应用的临床意义。方法 2017年1月-2017年12月,我院120转运中心长途转运接收786例机械通气新生儿,786例患儿随机分为常规气道护理(对照组)和转运途中应用一次性湿热交换器组(治疗组),对比转运过程中的吸痰次数、肉眼可见痰痂形成率、堵管发生率、脱管发生率、人机对抗发生率。结果研究数据显示治疗组吸痰次数、肉眼可见痰痂形成率、堵管发生率、脱管发生率、人机对抗发生率有显著性差异(P<0.05)明显低于对照组。结论在机械通气新生儿长途转运中,一次性湿热交换器的可减少转运患儿吸痰次数发生率、降低肉眼可见痰痂形成率、堵管发生率、脱管发生率、人机对抗发生率具有明显优越性,值得推广。     

基于频数分析法的骨伤科中成药用药规律研究

目的：探讨骨伤科中成药的用药规律，为临床合理用药及新药开发提供参考。方法：以《中国药典》2015年版一部收载的骨伤科类中成药共149个为研究对象，运用频数分析的方法研究其主治病症、所用剂型、各类方剂高频药物、核心药物组成，分析骨伤科中成药用药规律。结果：常用骨伤科中成药中治疗骨关节痹症的最多，其次为跌打损伤和骨关节退行性疾病的中成药；剂型以胶囊剂、片剂、丸剂为主；以活血化瘀药、祛风湿药、补虚药为核心药物组合，各类方剂中三者比例偏重不同。结论：通过对研究结果进行分析，提出了新药研发的方向。     

骨形成蛋白2基因修饰的老年大鼠骨髓间充质干细胞成骨分化能力的研究

目的观察年龄因素对骨髓间充质干细胞(marrow mesenchymal stem cells, MSCs)成骨分化能力的影响;了解基因治疗对老年大鼠MSCs成骨分化能力的影响. 方法 1月龄(幼年组)、9月龄(成年组)及24月龄(老年组)雄性Wistar大鼠各6只,取MSCs经体外分离、培养及携带骨形成蛋白2(bone morphogenetic protein 2,BMP-2)基因的腺病毒载体(Ad-BMP-2)转染后,定量检测BMP-2、碱性磷酸酶(alkaline phosphate,ALP)表达,以及成骨细胞标志性蛋白:Ⅰ型胶原、骨涎蛋白(bone sialoprotein,BSP)和骨桥素(osteopontin, OPN)的表达.将转染的各组MSCs分别与磷酸三钙(tricalcium phosphate, TCP)复合后植入裸鼠体内,3周后取材,比较各组诱导异位成骨能力. 结果 ELISA检测表明BMP-2基因修饰的MSCs可以有效表达BMP-2,且表达量在各年龄组间差异无统计学意义(P>0.05);各组ALP于诱导后第9天达高峰,但组间差异均无统计学意义(P＞0.05);诱导后第7天,RT-PCR半定量检测示各组均有成骨细胞特征性蛋白,即:Ⅰ型胶原、OPN及BSP的明显表达,表达量在各组间差异无统计学意义(P>0.05);BMP-2基因转染的MSCs与TCP复合后可诱导裸鼠体内异位成骨,各组成骨量差异无统计学意义(P>0.05). 结论 BMP-2基因修饰的老年大鼠MSCs可以恢复成骨分化能力,基因治疗可能为老年性骨骼疾病提供一种新的治疗途径.     

Concerns for medical radiation programs in Australian universities

The Australian higher education system is in a state of great change. The Federal education minister, Dr Brendan Nelson, has indicated that he intends to continue introducing far-reaching reforms that will impact significantly on how universities conduct teaching and research. The future allocation of government funding for university programs, including those in medical radiation, will have a significant effect on how those programs are delivered and could even determine whether programs remain viable. There will be a financial imperative for academic departments to strengthen research activity and to obtain funding from non-government sources, such as full-fee paying students, in order to generate enough income to cover program delivery. Medical radiation education in Australia is also facing many other challenges. Some of these are longstanding, such as the high cost of medical radiation program delivery, poor levels of research activity and difficulty in recruiting and retaining academic staff. Other problems have arisen recently, such as increased competition for students and a critical shortage of available training placements in clinical practice. The aim of this paper is to raise and explore these issues from a university perspective.
