Brève biographie de Pierre-Antoine Prost

Prost has hardly left his name in history as Dr. Blanche's predecessor in Montmartre. He is, however, the author of an original scientific work based on the anatomoclinical method. Military surgeon then civilian became doctor of medicine, founder and director of an important health house for lunatics, then merchant passementerie before returning to the practice of the art of healing, he was especially one of the first French alienists.     

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。     

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。     

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.     

Changes in the SF-12 among Depressed Elders Six Months after Discharge from an Inpatient Geropsychiatric Unit

Using the SF-12 to measure physical and mental functioning, the authors examine the intra-individual changes in health-related quality of life (HRQOL) 6 months post-discharge for depressed older adults. In addition, they examine three sets of predictors that might influence these changes. The sample of depressed older adults was recruited from an inpatient geropsychiatry unit. Although their physical and mental health scores on the SF-12 were lower than comparable norms, the sample showed an average increase in their mental functioning but a decrease in the physical functioning over the 6 months. Negative life-events were significant predictors of people who reported no change in their mental health functioning and decreases in their physical health functioning. Interestingly, those who experienced positive life events were more likely to report declines and younger participants were more likely to report no change in their physical functioning. The findings indicate that the effects of depression on HRQOL can have enduring effects on a sample of previously hospitalized older adults. The significance of life event changes might signify the importance of taking into account non-traditional areas of medical interventions. Further, the findings indicate the usefulness of the SF-12 quantifying HRQOL outcomes.

顽固性下颌磨牙根尖周炎患者的治疗和护理讨论

目的治疗顽固性下颌磨牙根尖周炎。并尽量减少对牙周膜的机械性损伤。方法采用下牙槽神经阻滞麻醉,并配合局部麻醉。拔牙钳的尖置放于釉牙骨质界以上,采用颊舌向摆动的方式将患牙拔下。在不断滴有生理盐水的条件下,立即用高速车针磨除患牙根尖2￣3mm的牙体组织,根管内3￣5mm深的充填物要用圆钻将其清除,再用牙胶尖和氢氧化钙糊剂充填。将患牙再植入牙槽窝之前,务必用生理盐水将牙槽窝冲洗干净,要求严格控制在15分钟内完成再植,并尽量减少对牙周膜的机械性损伤。再植牙齿一般不需要夹板固定,必要时可采用缝线缝合固定。结果我们选择的5例患者,术后随访1￣2年,1例患者再植失败,4例患者再植成功。结论特异性再植术治疗顽固性下颌磨牙根尖周炎疗效理想,而且较易掌握。     

医疗护理安全与护士的职业道德

目的:探讨医疗护理安全与护士职业道德水平的关系。方法:分析目前护理不安全因素,寻找相应对策。结果:医疗护理安全大大提高,医疗纠纷发生率明显下降。结论:在医疗护理安全活动中,护理安全担当着一个重要角色。通过对护士进行职业道德教育、素质教育及法制教育等措施,提高了医疗、护理安全,减少了医疗纠纷发生。
