摘要： 肝细胞癌大多数是由慢性肝病发展而来,术后并发营养不良的概率较高,严重影响患者预后。目前临床上进行营养评估的方法有很多,但国内外尚未建立统一的营养评估标准。本综述查阅国内外文献,归纳总结常见的营养状况评估工具及研究进展,为肝癌患者术前营养状况的评估提供参考。综合营养评估工具相对于传统营养指标能更准确地反映肝癌患者的营养状况,临床上在参考传统营养指标的同时应结合使用CONUT、NRI、NRS-2002等多种营养评估工具对患者进行评估。

摘要： This paper presents a new Double-E-Triple-H-Shaped NRI(negative refractive index)metamaterial(MM)for dual-band microwave sensing applications.Here,a horizontal H-shaped metal structure is enclosed by two face-to-face E-shaped metal structures.This double-E-H-shaped design is also encased by two vertical H-shaped structures along with some copper links.Thus,the Double-E-Triple-H-Shaped configuration is developed.Two popular substrate materials of Rogers RO 3010 and FR-4 were adopted for analyzing the characteristics of the unit cell.The proposed structure exhibits transmission resonance inside the S-band with NRI and ENG(Epsilon Negative)metamaterial properties,and inside the C-band with ENG and MNG(Mu Negative)metamaterial properties.A good effective medium ratio(EMR)of 8.06 indicates the compactness and effectiveness of the proposed design.Further analysis has been done by changing the thickness of the substrate material as well and a significant change in the effective medium ratio is found.The validity of the proposed structure is confirmed by an equivalent circuit model.The simulated result agrees well with the calculated result.For exploring microwave sensing applications of the proposed unit cell,permittivity and pressure sensitivity performance were investigated in different simulation arrangements.The compact size,effective parameters,high sensitivity and a good EMR represent the proposed metamaterial as a promising solution for S-band and C-band microwave sensing applications.

摘要： 目的:对中枢神经细胞瘤CT、MRI对比分析及鉴别诊断进行研究。方法:将2019年3月至2020年3月期间在我院接受治疗的42例中枢神经细胞瘤病患作为此次研究的研究对象,对其CT检查以及MRI检查中存在的特征进程观察分析,同时将其和病理诊断结果相比较,总结对比整理其诊断的准确概率。结果:中枢神经细胞瘤的主要发生位置包括:小脑蚓部、额叶、透明隔、胼胝体内壁、第四脑室以及侧脑室壁等。特征主要表现为在胼胝体壁间或者是侧脑室中呈现“索条”状的牵拉影像以及丝瓜瓤状或者是蜂窝状的变化;在CT检查中,其表现主要是稍微高一些的信号或者是等信号,在MRI检查中则主要呈现稍微低一些的信号或者是等信号,将扫描增强之后将会呈现中度或者是轻度的强化;CT符合病理诊断的概率是54.76%。而MRI符合病理诊断的概率是73.80%。结论:中枢细胞瘤的影像学表现以及发病位置均存在一定的特质,在对其进行鉴别诊断时,应当对其临床表现以及影像学表现进行详细、全面的分析及研究,从而使诊断准确率得到一定程度的提升,为病患后续的治疗提供帮助。

摘要： 分析磁共振成像诊断强直性脊柱炎的临床价值.选取在我院进行治疗的AS患者45例为研究对象,分别进行X线、CT及NRI检查,比较三种检测方式诊断早、中、晚期强直性脊柱炎的诊断结果.CT及NRI诊断早期强直性脊柱炎的灵敏度较X线诊断明显提高,差异显著(P0.05).NRI诊断强直性脊柱炎效果较好,可有效提高早期强直性脊柱炎检出情况,值得临床推广.

摘要： Edivoxetine is a highly selective norepinephrine reuptake inhibitor (NRI) that has been investigated in short-term studies as adjunctive therapy to?selective serotonin reuptake inhibitor antidepressants (SSRIs) in patients with major depressive disorder (MDD) who were partial responders to their SSRIs. This 52-week open-label study investigated the safety and tolerability of longer-term treatment with adjunctive edivoxetine in patients with MDD in Japan, who had completed one of two placebo-controlled acute studies of edivoxetine as adjunctive therapy to SSRIs. All patients continued on their stable dose of SSRI. Two hundred eighty-eight patients were enrolled and assessed for up to 1 year using standard safety and tolerability measures. Of these, 195 patients previously received only placebo in the parent study and, therefore, were first exposed to edivoxetine in this study. Approximately 46% of patients completed the study. The most frequently cited (>5%) reasons for discontinuation were sponsor decision (19.4%, which included patients discontinued due to early study termination), adverse event (17.4%) and subject decision (8.7%). Adverse events leading to discontinuation in more than 2 patients (>1%) were palpitations, vomiting, hepatic function abnormal, hypertension, nausea, and tachycardia. Treatment-emergent elevations in diastolic blood pressure and pulse were at least twice that reported in the literature for non-Asian patients. Twenty percent of patients had sustained elevations in pulse. Treatment-emergent changes in laboratory measures were small and not clinically meaningful. Assessment across all safety measures in this study indicated that the safety profile of edivoxetine was consistent with that expected for a selective NRI.
