  • 非接触式红外线额温枪与水银体温计测量结果比较

    目的对比非接触式红外线额温枪与水银体温计测量结果的差异,为临床护理提供借鉴和参考。 方法2014 年6 月3 日- 6 日同时使用水银体温计及非接触式红外线额温枪测量842 例次患者的腋窝及额头温度,对两种测量结果进行分析。 结果842 例次患者非接触式红外线额温枪测量的平均体温为(36.65±0.29)℃,水银体温计测量的平均体温为(36.55±0.38)℃。两组测量结果呈显著正相关(r=0.520,P < 0.01),数值差异有统计学意义(t=?8.023,P < 0.05)。 结论非接触式红外线额温枪的测量值不准确,对于其可完全替代水银体温计的说法不可取。但两种测温方式均各有优缺点,如何制作出同时兼有传统水银体温计的准确性及红外线体温测量仪的方便快捷的新型体温测量器材是下一步研究的方向。

  • Meta-analysis of the difference of peripheral inflammatory factors in Alzheimer’s disease and vascular dementia

    ObjectiveTo systematically review the data of peripheral inflammatory markers in patients with Alzheimer’s disease (AD) and vascular dementia (VaD) to further indicate pathogenesis and antidiastole.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect studies on peripheral inflammatory markers in patients with AD and VaD from inception to July 2020. Two reviewers independently screened literature, extracted data, and assessed risk of bias of included studies, and meta-analysis was performed by using Stata 15.1SE software.ResultsA total of 30 studies involving 2 377 patients were included. The results of meta-analysis showed that the IL-6 level was higher in VaD group than that in AD group (SMD=−0.477, 95%CI −0.944 to −0.009, P=0.046). However, there were no statistical difference in peripheral IL-1β (SMD=−0.034, 95%CI −0.325 to 0.257, P=0.818), TNF-α (SMD=0.409, 95%CI −0.152 to 0.970, P=0.153) or CRP (SMD=0.277, 95%CI −0.228 to 0.782, P=0.282) levels.ConclusionsThese findings suggest that IL-6 may be sensitive markers to distinguish AD from VaD. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the conclusions.

  • Practice of management of day surgery in a multi-district public hospital

    Beijing Tongren Hospital of Capital Medical University (Beijing Tongren Hospital) is one of the earliest tertiary public hospitals to offer day surgery in China. Over the past decade, the proportion of day surgery has exceeded 60%. Beijing Tongren Hospital has restructured its medical resources according to the functional positioning of each division, establishing four types of day surgery centers or wards characterized by “platform” “discipline” “disease type” and “service” to meet patients’ diverse needs. At the same time, it ensures homogeneous services for patients through unified admission standards, pathway processes, and quality control indicators. This effectively balances the standardization and individualization of day surgery across different hospital districts, further enhancing the quality and efficiency of day surgical services. This article summarizes the management experience and effectiveness of day surgery at Beijing Tongren Hospital.

  • Gas chromatography-mass spectrometry study on composition of volatile organic compounds in exhaled breath of radiation-damaged rats

    Objective To explore composition of volatile organic compounds (VOCs) in exhaled breath of low-dose radiation-damaged Sprague-Dawely (SD) rats by thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS), and search for the differential metabolites of VOCs in the series of rats after radiation damage, and establish a noninvasive radiation damage detection method. Methods SD rats were randomly divided into five groups (a blank group, a 0.5-Gy group, a 1-Gy group, a 2-Gy group, and a 3-Gy group), with 8 rats in each group. A low-dose radiation injury model was established in rats. After the cobalt source radiation damage was performed, the body weight of rats was recorded, peripheral blood hematology was analyzed, and the exhaled breath of rats was collected on the 1st, 5th, 9th and 13th day. The composition of VOCs in the exhaled breath was analyzed by using the TD30-GC-MS technique, and multivariate statistical analyses were carried out to explore and obtain the differentiated metabolites after the radiation damage. Results After radiation damage, the rats showed a short-term decrease in body weight, peripheral blood and lung tissue sections were different, and the content of VOCs components in the exhaled breath of the damaged rats was significantly different from that of the rats in the blank group. Among them, four VOCs, acetophenone, nonanal, decanal and tetradecane increased, while heptane, chlorobenzene, paraxylene and m-dichlorobenzene decreased. Conclusions Through the GC-MS analysis of the exhaled breath of rats, eight components of VOCs in the exhaled breath of rats can be used as differential metabolites of radiation damage. This study lays a foundation for the establishment of a GC-MS analysis method for the components of VOCs in the exhaled breath of rats, as well as for the development of a nondestructive analytical assay for biological radiation damage.
