Meta-Analysis of Saturated Fatty Acid Intake and Breast Cancer Risk

The associations between saturated fatty acid (SFA) consumption and risk of breast cancer (BC) remains inconclusive. Therefore, we conducted this meta-analysis to determine the quantitative relations between dietary SFA intake and incidence of BC.Literatures published up to April 2015 were systematically screened through Pubmed and Web of Science. Relevant publication quality was evaluated by conducting the Newcastle-Ottawa scale. We used fixed effects models or random effect models to calculate the summary relative risks (RRs) and odds ratios (ORs), and conducted sensitivity analyses and evaluated the publication bias.We identified a total of 52 studies (24 cohort studies and 28 case–control studies), with over 50,000 females diagnosed with BC. The associations between dietary SFA intake and risk of BC were 1.18 for case–control studies (high vs low intake, 95% confidence interval [CI] = 1.03–1.34) and 1.04 for cohort studies (95% CI = 0.97–1.11). When restricted analyses to population-based studies, positive associations were observed for both cohort (RR [95% CI] = 1.11 [1.01–1.21]) and case–control studies (OR [95% CI] = 1.26 [1.03–1.53]). Additionally, for case–control studies, significant positive associations between higher SFA intake and BC risk were observed for Asian (OR [95% CI] = 1.17 [1.02–1.34]) and Caucasian (OR [95% CI] = 1.19 [1.00–1.41]), as well as for postmenopausal women (OR = 1.33, 95% CI: 1.02–1.73). In contrast, higher dietary SFA intake was not associated with risk of BC among premenopausal women, in cohort studies or hospital-based studies.A positive association between higher dietary SFA intake and postmenopausal BC risk was observed in case–control but not in cohort studies. More studies are warranted to confirm these findings.     

Host–microbiome interactions: the aryl hydrocarbon receptor as a critical node in tryptophan metabolites to brain signaling

ABSTRACT

Tryptophan (Trp) is not only a nutrient enhancer but also has systemic effects. Trp metabolites signaling through the well-known aryl hydrocarbon receptor (AhR) constitute the interface of microbiome-gut-brain axis. However, the pathway through which Trp metabolites affect central nervous system (CNS) function have not been fully elucidated. AhR participates in a broad variety of physiological and pathological processes that also highly relevant to intestinal homeostasis and CNS diseases. Via the AhR-dependent mechanism, Trp metabolites connect bidirectional signaling between the gut microbiome and the brain, mediated via immune, metabolic, and neural (vagal) signaling mechanisms, with downstream effects on behavior and CNS function. These findings shed light on the complex Trp regulation of microbiome-gut-brain axis and add another facet to our understanding that dietary Trp is expected to be a promising noninvasive approach for alleviating systemic diseases.     

新冠肺炎疫情下艾灸防治帕金森病的临床应用分析＊

帕金森病（Parkinson''s disease，PD）是仅次于阿尔茨海默病的世界第二大神经系统退行性疾病，随着老龄化社会的到来，PD患病率呈明显上升趋势。全球爆发的新型冠状病毒肺炎（简称新冠肺炎）是一种急性传染性疾病，严重威胁人们的身体健康和生命安全。PD患者大多为老年人且合并有基础疾病，体质普遍较弱，是新冠肺炎的易感人群，一旦染病则发展为重症的风险很高。中医艾灸疗法在治疗PD及防治疫病方面发挥了很好的辅助治疗效果。通督扶阳灸法联合强壮穴艾灸治疗，既可以帮助PD患者改善临床症状，延缓病情进展，又可以提高机体免疫功能，增强抗病能力而防治新冠肺炎。     

The Relationship between College Graduate’s Dual Self-Consciousness and Job Search Clarity: The Mediating Role of Perceived Stress

The aim of the study was to explore the relationship between college graduates’ dual self-consciousness, job search clarity and perceived stress, and reveal the mediating role of perceived stress between dual self-consciousness and job search clarity. In this study, 467 college graduates were investigated using the Dual Self-Consciousness Scale, Job Search Clarity Scale, and Perceived Stress Scale. After controlling for gender, age, and region, the results revealed that: (1) private self-consciousness has a significant positive predictive effect on job search clarity; (2) perceived stress has a significant negative predictive effect on job search clarity; (3) perceived stress plays partial mediation effects between private self-consciousness and job search clarity; (4) perceived stress plays complete mediation effects between public self-consciousness and job search clarity; (5) perceived stress has suppressing effects between public self-consciousness and job search clarity.     

左旋布比卡因腰-硬联合阻滞在下肢手术的应用

目的探讨0.75%左旋布比卡因用于蛛网膜下隙阻滞的临床效果及安全性。方法随机选择ASAⅠ～Ⅱ级的40例骨科下肢手术患者(股骨干及髋关节大手术的患者),随机均分成两组:L组腰麻用药为0.75%左旋布比卡因15mg,容量为2.5ml;B组腰麻用药为0.75%布比卡因,剂量及容量同L组。术中必要时经硬膜外导管注入2%利多卡因。术中监测BP、HR、SpO2、RR的变化并观察围术期不良反应的发生。结果两组最高阻滞平面及到达时间、麻醉持续时间、肌松效果及达到最大肌松效果时间差异均无显著意义。两组均无神经系统的不良反应。结论0.75%左旋布比卡因用于腰-硬联合麻醉骨科下肢手术安全有效,效果与0.75%布比卡因相比差异无显著意义。
