手术烟雾对大鼠生理功能损害的实验研究

目的 探讨手术烟雾对生理功能的危害性及采取防护措施的必要性。 方法 采用60只SD大鼠，随机分为空白组、烟雾组及干预组三组，每组20只。空白组不接受烟雾刺激，无任何防护；烟雾组和干预组大鼠在烟雾环境中安置30min；干预组大鼠提前接受预防措施。连续两周后检测手术烟雾环境中大鼠生理、生化指标及预防措施的有效性。 结果 使用电刀3min后，空气质量受到严重污染，并且随电刀使用时间增加而持续下降；连续两周后烟雾组大鼠心功能、血流动力学、呼吸功能受到明显损害，血清炎性因子IL-6、IL-8和TNF α浓度明显增加；而干预组大鼠生理功能受到明显保护，炎性因子浓度降低。在两周实验期内，手术烟雾对肝肾功能无明显影响。结论 手术烟雾会引起明显的生理功能损害，采取防护措施能起到良好的保护作用。     

Using cortical non-invasive neuromodulation as a potential preventive treatment in schizophrenia - A review

BackgroundEvidence suggests that schizophrenia constitutes a neurodevelopmental disorder, characterized by a gradual emergence of behavioral and neurobiological abnormalities over time. Therefore, applying early interventions to prevent later manifestation of symptoms is appealing.ObjectiveThis review focuses on the use of cortical neuromodulation in schizophrenia and its potential as a preventive treatment approach. We present clinical and preclinical findings investigating the use of neuromodulation in schizophrenia, including the current research focusing on cortical non-invasive stimulation and its possibility as a future preventive treatment.MethodsWe performed a search in Medline (PubMed) in September 2020 using a combination of relevant medical subject headings (MeSH) and text words. The search included human and preclinical trials as well as existing systematic reviews and meta-analysis. There were no restrictions on language or the date of publication.ResultsNeurodevelopmental animal models may be used to investigate how the disease progresses and thus which brain areas ideally should be targeted at a given time point. Here, abnormalities of the prefrontal cortex have been often identified as an early and persistent impairment in schizophrenia. Currently there is insufficient evidence to either support or refute the use of neuromodulation to the cortex in adult patients with already manifested symptoms. However, preclinical results show that early non-invasive neuromodulation to the prefrontal cortex of adolescent animals, sufficiently prevents later psychosis-relevant abnormalities in adulthood. This points to the promising potential of cortical non-invasive neuromodulation as a preventive treatment when applied early in the course of the disease.ConclusionPreclinical translational-oriented findings indicate, that neuromodulation to cortical areas offers the possibility of targeting early neuropathology and through this diminish the progression of a later schizophrenic profile. Further studies are needed to investigate whether such early cortical stimulation may serve as a future preventive treatment in schizophrenia.     

浅谈医疗设备预防性保养的重要性

对于医疗设备来说,其临床医疗中有十分重要的作用,而且医疗设备的实际运行效率也与医院的经济效益有直接的关系,但是在大部分医院中仍然采用传统的医疗设备养护方式,导致医疗设备的维护缺乏科学性,从而增加了医疗设备故障的发生率,并且也影响了实际应用的效果,严重的情况下甚至会发生医疗事故。基于此,该文主要对医疗设备预防性保养的重要性与方法进行分析,希望能够使医疗设备的性能得到最优化的体现,使其能够更好地为医疗服务的开展提供支持。     

Dressings as an adjunct to pressure ulcer prevention: consensus panel recommendations

The formulation of recommendations on the use of wound dressings in pressure ulcer prevention was undertaken by a group of experts in pressure ulcer prevention and treatment from Australia, Portugal, UK and USA. After review of literature, they concluded that there is adequate evidence to recommend the use of five‐layer silicone bordered dressings (Mepilex Border Sacrum^® and 3 layer Mepilex Heel^® dressings by Mölnlycke Health Care, Gothenburg, Sweden) for pressure ulcer prevention in the sacrum, buttocks and heels in high‐risk patients, those in Emergency Department (ED), intensive care unit (ICU) and operating room (OR). Literature on which this recommendation is based includes one prospective randomised control trial, three cohort studies and two case series. Recommendations for dressing use in patients at high risk for pressure injury and shear injury were also provided.     

Enumerating the preventive youth health care workforce: Size,composition and regional variation in the Netherlands

The progress in workforce planning in preventive youth health care (YHC) is hampered by a lack of data on the current workforce. This study aimed to enumerate the Dutch YHC workforce. To understand regional variations in workforce capacity we compared these with the workforce capacity and the number of children and indicators of YHC need per region.A national survey was conducted using online questionnaires based on WHO essential public health operations among all YHC workers. Respondents (n = 3220) were recruited through organisations involved in YHC (participation: 88%).The YHC workforce is multi-disciplinary, 62% had >10 years working experience within YHC and only small regional variations in composition existed. The number of children per YHC professional varied between regions (range 688–1007). All essential public health operations were provided and could be clustered in an operational or policy profile. The operational profile prevailed in all regions. Regional differences in the number of children per YHC professional were unrelated to the indicators of YHC need.The essential public health operations provided by the YHC workforce and the regional variations in children per YHC professional were not in line with indicators of YHC needs, indicating room for improvement of YHC workforce planning. The methodology applied in this study is probably relevant for use in other countries.     

56例临床输血不良反应原因分析

目的:分析临床输血过程中发生输血不良反应的原因,探讨有效的预防措施。方法:回顾2012—2014年输注由我站提供的血液制品后发生输血不良反应患者56例,分析输血不良反应发生的原因。结果:21615人次输血中,发生不良反应56例,发生率为0.3%,其中非溶血性发热反应为32例,占57.1%,过敏反应为24例,占42.9%,未发现其他输血不良反应。结论:临床上应加强对输血全过程的监管,遵循合理科学用血原则,采用新的输血技术,大力提倡自身输血,确保临床输血的安全性。     

Preventing tuberculosis in children: A global health emergency

It is estimated that 20 million children are exposed to tuberculosis (TB) each year, making TB a global paediatric health emergency. TB preventative efforts have long been overlooked. With the view of achieving “TB elimination” in “our lifetime”, this paper explores challenges and potential solutions in the TB prevention cascade, including identifying children who have been exposed to TB; detecting TB infection in these children; identifying those at highest risk of progressing to disease; implementing treatment of TB infection; and mobilizing multiple stakeholders support to successfully prevent TB.
