However, literature specific to stroke-associated pneumonia (SAP) on this topic is very small. Further, how to differentiate the predictive value of hyperglycemia with and without abnormal HbA1C in such patients is still a matter of debate and no universal consensus. We evaluated hyperglycemia as a marker for SAP in patients with ICH to assess its usefulness as a potential predictor. Materials and methods: Clinical characteristics for a sample of 551 patients with acute ICH were collected from the Beijing Tiantan Hospital of Capital Medical University, Beijing, China. Possible associated risk factors of SAP were reviewed. Hyperglycemia and HbA1C on admission were the main hypothetic predictor, SAP occurring within the first 7 days is the primary outcome. Results: The cohort study includes 551 hospitalized patients. The prevalence of hyperglycemia was 52.5% and SAP occurred in 147 (26.7%). The incidence of SAP was higher in the group with hyperglycemia than those without hyperglycemia (37.7% versus 14.5%, p 6.5) (OR, 1.57;95%CI, 0.81 - 3.23) had not been shown to be associated with SAP. Conclusions: In this hospital-based cohort of patients presenting with acute intra-hemorrhage, hyperglycemia on admission was associated significantly with SAP. The association was stronger for hyperglycemia with normal HgbA1C than for hyperglycemia with high HgbA1C. Hyperglycemia with normal HgbA1C might be a more sensitive predictor of early acute complication, such as SAP.展开更多
文摘针对目前红花丝人工采收效率及机械化程度低等问题,提出了一种梳齿式红花丝采摘机构。以该采摘机构的凸轮为研究对象,利用解析法建立了从动件的数学方程式,并结合Mat Lab编程软件得到了凸轮的轮廓曲线。通过Solid Works软件建立了三维模型,采用ADAMS软件和Solid Works Simulation分别进行了仿真分析与有限元分析。结果表明:所设计的凸轮完全能够满足红花丝的采摘要求,同时为进一步研究采摘凸轮机构提供了理论依据。
