应用基于密度泛函理论的第一性原理赝势平面波法和超晶胞法对Mo含量(原子分数)为6.25%～37.5%的Ti-Mo二元合金的结合能和电子结构进行了计算;通过晶胞拉伸变形过程中单原子结合能随拉伸方向晶格常数的变化曲线计算出了合金成分为Ti15Mo1,Ti14Mo2,Ti13Mo3,Ti12Mo4,Ti11Mo5和Ti10Mo6的Ti-Mo二元合金在单向拉伸状态下的理论强度。研究了Mo元素对增强β钛合金稳定性,提高β钛合金强度的作用及作用机理。结果表明:随着Mo元素含量的增加,Ti-Mo二元合金β相的稳定性和理论强度都有明显提高;态密度的分析表明,Ti,Mo成键作用的加强导致了合金理论强度的提高。

Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains *** A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of *** Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two *** Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

目的分析输血前微柱凝胶法交叉配血次侧凝集的原因及意义,为临床安全输血提供参考。方法统计2013年1月~2016年5月我院微柱凝胶法次侧交叉配血凝集患者,按照病种分组分析交叉配血次侧凝集的比例,次侧配血凝集率与输血次数、输血反应的相关性;采用抗人球蛋白试验、放散试验、抗体筛选鉴定、药物性抗体筛查及RBC形态结构分析等方法研究交叉配血次侧凝集的原因。结果调查分析微柱凝胶卡交叉配血45 672人次,其中325例次侧配血凝集,凝集率为0.71%;次侧配血凝集主要病种为血液系统疾病、ICU重症及急诊抢救、烧伤等;血液病患者次侧配血凝集率与输血次数、输血反应率、输血效率等均成正相关性(P0.05);次侧配血凝集原因主要有:患者红细胞形态结构变化、血浆蛋白影响、供者血清同种抗体、药物性抗体、加样量不当及技术因素等;由免疫因素与非免疫因素引起的次侧配血凝集原因的分类比较差异有统计学意义(P<0.05)。结论微柱凝胶法交叉配血次侧凝集的原因很多,非免疫因素导致交叉配血次侧凝集比例较高,输血反应与输注无效率较低;而免疫因素引起的次侧凝集比例低,但输注无效率高,且较易引起输血反应。
