目的：胃癌是我国最常见的恶性肿瘤之一，具有发病率高、死亡率高、预后差等特点，且癌细胞浸润及转移是影响其疗效而致患者死亡的主要原因。与EUS、MRI相比，螺旋CT是胃癌术前分期的主要影像学检查方法。胃癌螺旋CT是目前的研究热点之一。研究显示，低张水充盈螺旋CT三期增强扫描可全面评价胃癌的浸润及转移，准确评估术前分期。本研究旨在评价胃癌螺旋CT三期增强扫描TNM分期的准确性，探讨螺旋CT各种征象(包括病灶厚度、大小、强化特点、浸润深度、淋巴结转移和TNM分期)与手术病理之间的关系。方法：对43例胃癌病人术前行低张水充盈螺旋CT三期增强扫描，扫描前空腹，检查前10min肌注盐酸654-220mg，口服温水800-1200ml。先行平扫，然后分别于注射非离子型对比剂开始后25s(动脉期)，65-70s(门静脉期)，3-4min(延迟期)进行增强扫描。43例病人均于检查开始后一周内施行胃癌切除术，并将螺旋CT结果与手术病理及组织分化进行对照。结果： 1．螺旋CT上病灶大小与手术病理的浆膜侵犯、淋巴结转移和TNM分期均相关(P＜0.05) 2．螺旋CT上病灶强化方式与手术病理的淋巴结转移相关(P＜0.05)，与浆膜侵犯及TNM分期不相关。 3．螺旋CT对胃癌浸润深度的准确性分别为81.4％(35／43)，手术病理的浸润深度和TNM分期一致(P＜0.05)。 4．螺旋CT对胃癌淋巴结转移的准确率为72.9％(31／43)，手术病理的淋巴结转移和TNM分期一致(P＜0.05)。

本报告介绍了在控制条件下求垫片系数的一个探索性实验研究的结果。按专为此规划定的一个试验程序试验了一些石棉组分的垫片和缠绕式垫片,考虑的变量是垫片宽度和厚度,螺栓荷载,内压和泄漏率。试验是用一对4时ANSI(美国国家标准协会)B16.5,600磅具有理想法兰面的焊颈法兰在室温下进行的,用了氮和水的两种压力介质,以确定垫片系数用于气体和用于液体物料的不同之处,试验持续了两年。注意到了m和y系数有作为泄漏率,垫片宽度,介质压力和垫片初应力的一个函数的倾向。导出合适的经验公式。以图和表的形式介绍了结果。结果还表明所用的试验步骤是有可能确定控制参数列垫片性能的影响,并得出在垫片的操作范围内它的可靠的性能数据。结论是:控制参数之间存在有一个复杂的相互作用,ASME规范在这段时期所用关于m和y系数的推荐值是不成熟的。意识到需有一个广泛的试验计划,以便定量地建立起观察到的倾向。

Resolution Enhancement of Optical Surface Plasmon Resonance Sensor Using Metamaterial

In this paper, we present and discuss a an optical surface plasmon resonance （SPR） path to extend the enhancement of the resolution of sensor. Basically, our approach is to combine bi-metamaterial layers to design the SPR sensor. The calculation shows that the proposed SPR sensor structure has a preference over the conventional SPR sensors and bimetallic SPR sensors since it gives a much sharper reflectance dip and can achieve considerable sensitivity improvement when compared to the recently reported investigations. The effects of the metamaterial permittivity, permeability, and thickness on the reflectance curve are studied. It is also seen that metamaterial layers improve the field of the proposed SPR structure, which may provide a novel tool to significantly enhance the sensitivity and resolution of the sensors.

登革病毒依抗原性不同,可分为1、2、3、4四个血清型。它除了能导致一定范围内发热的典型登革热外,还能引致更严重的登革出血热和登革休克综合症。由于没有具体有效的治疗药物,目前尚无好的治疗登革热的方法,治疗方案多是支持性的。本实验评估了在2型登革病毒感染的人血源性巨噬细胞中沙棘叶提取物的抗登革病毒活性,选择巨噬细胞的原因是因为巨噬细胞是登革病毒感染的首要目标。受感染的细胞用沙棘叶提取物治疗并与市售的抗病毒药物利巴韦林作比较,研究发现沙棘叶提取物维持登革病毒感染细胞活力的能力几乎等同于利巴韦林。传统的空斑试验进一步确定了沙棘叶提取物的抗登革病毒活性。这些试验结果表明,沙棘叶提取物具有显著的抗登革病毒活性及治疗登革热的潜力。
