不同灸温下穴位涂抹辣椒素对佐剂性关节炎疗效的影响

目的:以佐剂性关节炎为载体,研究穴位涂抹辣椒素(TRPV1激动剂)在不同灸温下对艾灸治疗佐剂性关节炎疗效的影响,以证实艾灸起效需要适宜的灸温,并进一步探讨瞬时受体电位通道香草醛亚型1(简称TRPV1)与艾灸抗炎起效机制的关系。方法:将48只雄性SD大鼠随机分为空白组、模型组、38℃艾灸组、38℃实验组、45℃艾灸组、45℃实验组,用弗氏完全佐剂造成佐剂性关节炎模型,空白组与模型组不予处理;45℃实验组在双侧后三里、肾俞穴局部涂抹5%辣椒素,每隔10 min涂1次,共涂3次,再用艾条灸后三里、双肾俞,灸温控制在45℃;38℃实验组将灸温控制在38℃;38℃、45℃艾灸组仅艾灸;1次/d,每次每穴灸10 min,连续治疗5 d,治疗结束后检测患侧足趾肿胀度、血清IL-1β、TNF-α含量。结果:45℃艾灸组、38℃实验组、45℃实验组3个指标较模型组均明显降低(P<0.01);38℃艾灸组与模型组相比,肿胀度、IL-1β含量虽有下降趋势,但无统计学差异(P>0.05)。38℃与45℃艾灸组、38℃实验组与艾灸组、45℃实验组与艾灸组比较,炎症指标有明显统计学意义(P<0.01)。38℃实验组与45℃艾灸组比较,各指标无统计学意义(P>0.05)。结论:1艾灸抗炎需要适宜的灸温,其启动机制与TRPV1有关;2穴位涂抹辣椒素可降低艾灸抗炎所需的温度阈值,并能提高艾灸抗炎的疗效,其起效机制依赖于TRPV1。     

Notch promotes recurrence of dormant tumor cells following HER2/neu-targeted therapy

Breast cancer mortality is principally due to recurrent tumors that arise from a reservoir of residual tumor cells that survive therapy. Remarkably, breast cancers can recur after extended periods of clinical remission, implying that at least some residual tumor cells pass through a dormant phase prior to relapse. Nevertheless, the mechanisms that contribute to breast cancer recurrence are poorly understood. Using a mouse model of recurrent mammary tumorigenesis in combination with bioinformatics analyses of breast cancer patients, we have identified a role for Notch signaling in mammary tumor dormancy and recurrence. Specifically, we found that Notch signaling is acutely upregulated in tumor cells following HER2/neu pathway inhibition, that Notch signaling remains activated in a subset of dormant residual tumor cells that persist following HER2/neu downregulation, that activation of Notch signaling accelerates tumor recurrence, and that inhibition of Notch signaling by either genetic or pharmacological approaches impairs recurrence in mice. Consistent with these findings, meta-analysis of microarray data from over 4,000 breast cancer patients revealed that elevated Notch pathway activity is independently associated with an increased rate of recurrence. Together, these results implicate Notch signaling in tumor recurrence from dormant residual tumor cells and provide evidence that dormancy is a targetable stage of breast cancer progression.     

卫生应急服务覆盖程度及其效果：基于辽宁吉林两省的实证分析

目的分析辽宁吉林两省卫生应急服务覆盖程度及其工作效果，为辽宁吉林两省进一步完善突发公共卫生事件应急处置体系提供理论依据。 方法为了保持量化的原则，选取功能服务与公众需要的匹配程度这一具体指标来反映卫生应急服务覆盖程度，系统收集2000至2017年辽宁吉林两省卫生应急服务相关的文件和文献数据，摘录文件中所涉及的卫生应急服务三级预防功能服务的表述；摘录文献中涉及的卫生应急服务工作效果的表述，采用"五分度评分法"判定工作效果；采用Speraman相关、单因素回归方法分析辽宁吉林两省卫生应急服务覆盖范围与辽宁吉林两省工作效果的关系。 结果2017年，辽宁省卫生应急服务覆盖程度达到56.5%，吉林省达到64.7%。辽宁吉林两省卫生应急服务覆盖程度与卫生应急工作效果都呈正相关关系(P均<0.05)，并且吉林省的显著性更强。 结论吉林省在卫生应急服务覆盖程度表现更佳。同时也验证了卫生应急服务覆盖程度量化方法和工作效果评价方法是可行的，可应用于公共卫生的其他领域。     

Family nursing with the assistance of network improves clinical outcome and life quality in patients underwent coronary artery bypass grafting: A consolidated standards of reporting trials-compliant randomized controlled trial

Background:Family nursing with the assistance of network (FNAN) improves nurses’ practice and provides family/community-oriented nursing care. This study aimed to explore the effects of FNAN on the clinical outcome and life quality of coronary atherosclerotic heart disease (CHD) patients underwent coronary artery bypass grafting (CABG).Trial Design:This study is a randomized, placebo-controlled and double-blind trial.Methods:One-hundred and twelve patients underwent CABG were randomly divided into control group (CG, routine family nursing care) and experimental group (EG, FNAN) and the allocation ratio was 1:1. The situation of anxiety and depression were analyzed using the Hamilton Anxiety Scale (HAMA) scale and Hamilton Depression Scale (HAMD). Sleep quality was measured by using Pittsburgh Sleep Quality Index (PSQI). Lung function parameters were measured, including minute ventilation (MVV), partial pressure of oxygen (PaO₂), partial pressure of arterial carbon dioxide (PaCO₂), oxygen saturation measurement by pulse oximetry (SpO₂), forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC). Life quality was measured by using Chronic Obstructive Pulmonary Disease Assessment Test (CAT).Results:After a 3-month intervention, 10 and 6 patients were lost in the CG and EG groups, respectively. The scores of HAMA, HAMD, PSQI and CAT were reduced in the EG group when compared with the CG group (P < .05). The values of MVV, PaO₂, SpO₂, FEV1 and FVC in the EG group was higher than those in the CG group whereas the levels of PaCO₂ in the EG group was lower than those in the CG group (P < .05). PSQI score had a strong relationship with the values of MVV, PaO₂, PaCO₂, SpO₂, FEV1, and FVC.Conclusion:FNAN improves the clinical outcome and life quality in the patients underwent CABG.     

吉林辽宁两省18年来的目标设置对突发公共卫生事件应急工作落实情况的关联研究
