Huayu Pill (化瘀丸) Promotes Fluorescent Doxorubicin Delivery to Tumors in Mouse Model of Lung Cancer

Objective: To study the effect and mechanism of Huayu Wan (化瘀丸, HYW) in combination of chemotherapy of tumor treatment. Methods: HYW serum was added in Lewis cells to assess its impact on fluorescent doxorubicin delivery in vitro. Then, Lewis tumor cells was implanted in C57BL/6 mice via xenograft transplantation. Tumor growth was measured and signal intensity corresponding to blood flow was assessed by laser doppler perfusion imaging (LDPI). Finally, the effect of HYW on the efficacy of doxorubicin was studied. Results: HYW can improve the transfer of fluorescent doxorubicin into cells. The blood flow signal in the tumor tissues of the HYW group was higher than that of the control group (P<0.01). Furthermore, HYW improved drug delivery of doxorubicin to tumor tissues, and this activity was associated with HYW-induced microvascular proliferation (P<0.01). Conclusions: HYW can promote microangiogenesis and increase blood supply in tumor tissues, which in turn may increase the risk of metastasis. At the same time, HYW increases drug delivery and improves the efficacy of chemotherapy drugs through vascular proliferation. Therefore, rational judgment must be exercised when considering applying HYW to an antitumor regimen.     

MicroRNA and mRNA profiling of cerebral cortex in a transgenic mouse model of Alzheimer’s disease by RNA sequencing

In a previous study,we found that long non-coding genes in Alzheimer’s disease(AD)are a result of endogenous gene disorders caused by the recruitment of microRNA(miRNA)and mRNA,and that miR-200a-3p and other representative miRNAs can mediate cognitive impairment and thus serve as new biomarkers for AD.In this study,we investigated the abnormal expression of miRNA and mRNA and the pathogenesis of AD at the epigenetic level.To this aim,we performed RNA sequencing and an integrative analysis of the cerebral cortex of the widely used amyloid precursor protein and presenilin-1 double transgenic mouse model of AD.Overall,129 mRNAs and 68 miRNAs were aberrantly expressed.Among these,eight down-regulated miRNAs and seven up-regulated miRNAs appeared as promising noninvasive biomarkers and therapeutic targets.The main enriched signaling pathways involved mitogen-activated kinase protein,phosphatidylinositol 3-kinase-protein kinase B,mechanistic target of rapamycin kinase,forkhead box O,and autophagy.An miRNA-mRNA network between dysregulated miRNAs and corresponding target genes connected with AD progression was also constructed.These miRNAs and mRNAs are potential biomarkers and therapeutic targets for new treatment strategies,early diagnosis,and prevention of AD.The present results provide a novel perspective on the role of miRNAs and mRNAs in AD.This study was approved by the Experimental Animal Care and Use Committee of Institute of Medicinal Biotechnology of Beijing,China(approval No.IMB-201909-D6)on September 6,2019.

跨专业合作情景模拟教学在手术室低年资护士培训中的应用效果评价

目的 使用跨专业合作情景模拟教学法对手术室低年资护士进行培训并评价其效果。方法 将某医院两个院区的低年资手术室护士作为研究对象，以老院区手术室32名低年资护士为对照组，新院区手术室34名低年资护士为实验组。实验组采用跨专业合作情景模拟教学方法进行培训，对照组采用科室常规教学方法进行培训，培训后对2组手术室低年资护士进行理论、手术室案例情景模拟考核，并采用问卷调查实验组护士的跨专业合作能力以及对跨专业合作情景模拟教学法的满意度。结果 实验组的理论成绩和手术室案例情景模拟、跨专业合作能力量表得分均高于对照组，两组比较差异均有统计学意义(P<0.05)。对实验组的问卷调查显示手术室低年资护士对跨专业合作情景模拟教学法满意度高，认可其教学效果。结论 跨专业合作情景模拟教学为手术室护士提供模拟手术场景，能够提高手术室护士的跨专业合作配合程度，提高低年资护士临床动手操作和适应能力，缩短临床工作适应时间，值得借鉴和推广。     

冠心病心绞痛的相关危险因素分析及院外延续性护理

目的:探讨冠心病心绞痛的相关危险因素分析及院外延续性护理的应用效果。方法:选取2019年10月1日~2020年10月1日收治的76例冠心病心绞痛患者为研究组,同期选取收治的76例其他疾病住院患者为对照组,分析心绞痛的相关危险因素。将研究组分为常规组和实验组各38例,常规组给予常规随访,实验组给予延续性护理,比较两组自我管理水平、不良心血管事件发生情况。结果:单因素分析结果显示,冠心病心绞痛发生与年龄、性别、吸烟史、基础病、婚姻状态、体质量指数(BMI)等因素存在相关性(P<0.05);多因素Logistic回归分析,男性、吸烟史、合并高血压、BMI>24为冠心病心绞痛的独立危险因素(P<0.05);实验组各项自我管理水平高于常规组(P<0.05),实验组不良心血管事件发生率低于常规组(P<0.05)。结论:冠心病心绞痛的发生与性别、吸烟史、基础病症、BMI等因素息息相关,冠心病心绞痛患者出院后给予院外延续性护理,可提高其自我管理水平,降低心绞痛复发和不良心血管事件发生风险。

Review of Chinese Journal of Traumatology in the year 2018

Trauma is one of the leading causes of death worldwide. It is an urgent task to strengthen the trauma care and prevent the complications. In 2018, Chinese Journal of Traumatology reported a series of trauma-related articles of which the contents include pre-hospital care, in-hospital care and complication prevention, et al, aiming to improve the treatment levels, decrease the trauma incidence, and reduce the trauma mortality and disability.
