大肠癌及癌旁组织中TAG-72抗原及两种凝集素PNA和DBA受体的表达

应用肿瘤相关糖蛋白７２抗原（ＴＡＧ－７２）的单抗７２－４５及两种凝集素ＰＮＡ和ＤＢＡ对不同组织分型的大肠癌及癌旁组织进行了研究。结果表明：大肠癌中ＴＡＧ－７２抗原及ＰＮＡ受体的表达阳性率分别为８５．３％和８９．３％，ＤＢＡ受体呈阴性；在癌旁组织中三者的表达阳性率分别为５０％、５３．３％和６３．３％；在正常大肠粘膜中ＴＡＧ－７２抗原及ＰＮＡ受体均呈阴性，而ＤＢＡ受体全部呈阳性。由此认为７２－４５单抗和ＰＮＡ可做为大肠癌的有效标记物，有助于大肠癌的诊断和预后。     

30例蚕蚀性角膜溃疡病理形态与发病机理探讨

本文报告30例蚕蚀性角膜溃疡的病理形态。本病属非化脓性的慢性炎症,角膜浅层实质破坏形成溃疡,角膜板层及溃疡边缘结膜见有淋巴细胞、浆细胞为主的炎细胞浸润和肉芽组织形成。活动期病变可见较多中性白细胞浸润。发病机理很复杂,主要与免疫反应有关。     

初级卫生保健试点县妇幼保健投入产出分析

  目的  分析2000 — 2017年京沪妇女保健财力资源适宜程度及孕产妇死亡率的变化趋势,明确2地差异,探讨妇女保健财力资源适宜程度。  方法  收集1995 — 2017年涉及京沪妇女保健财力投入政府主导问题（202篇）、投入总量问题（205篇）和投入增长问题（122篇）文献,综合投入政府主导适宜程度、投入总量适宜程度、增长适宜程度等3个指标,计算财力资源的适宜程度。运用Spearman相关、线性回归等分析妇女保健财力资源适宜程度与孕产妇死亡率的关系。  结果  北京妇女保健财力资源适宜程度从2000年的28.40 %升至2017年的42.60 %,上海则由22.60 %升至69.40 %,北京和上海的回归方程均有统计学意义（上海P < 0.01,北京P < 0.05）。  结论  京沪2地妇女保健财力资源适宜程度逐年提高,上海财力资源在孕产妇死亡率下降中作用更大,但财力投入稳定增长仍是薄弱环节;适宜的妇女保健体系应“政府负责、投入适宜、稳定增长”;验证了量化妇女保健财力资源适宜程度的可行性。     

鲁迅与解剖学研究述略

鲁迅在《我怎么做起小说来》一文中写道,"但我的来做小说,也并非自以为有做小说的才能……大约所仰仗的全在先前看过的百来篇外国作品和一点医学上的知识,此外的准备,一点也没有"[1].可见,鲁迅青年时期接受的医学教育,与之精神与艺术有着深刻的渊源.而鲁迅所说的"医学上的知识"中,对其影响最大的莫过于 "解剖学的知识".在鲁迅...     

葫芦巴碱调节肾移植术后代谢紊乱的应用前景

肾移植术后易发生糖、脂质等代谢紊乱,导致移植肾功能障碍及长期存活率降低。葫芦巴碱是一种具有多种生物活性的天然生物碱,具有改善糖、脂质等代谢紊乱的作用,可减轻肾脏的炎症反应、氧化应激及细胞凋亡,从而保护肾功能。因此,葫芦巴碱可能是调节肾移植术后代谢紊乱的潜在药物。本文对葫芦巴碱与糖代谢紊乱、脂质代谢紊乱、其他代谢紊乱及葫芦巴碱在肾移植中的应用前景进行综述,旨在为改善肾移植术后代谢紊乱、提高肾移植受者及移植肾的长期存活率提供参考。     

MRI contrast agents: Basic chemistry and safety

Magnetic resonance imaging (MRI) contrast agents are pharmaceuticals used widely in MRI examinations. Gadolinium‐based MRI contrast agents (GBCAs) are by far the most commonly used. To date, nine GBCAs have been commercialized for clinical use, primarily indicated in the central nervous system, vasculature, and whole body. GBCAs primarily lower the T₁ in vivo to create higher signal in T₁‐weighted MRI scans where GBCAs are concentrated. GBCAs are unique among pharmaceuticals, being water proton relaxation catalysts whose effectiveness is characterized by a rate constant known as relaxivity. The relaxivity of each GBCAs depends on a variety of factors that are discussed in terms of both the existing agents and future molecular imaging agents under study by current researchers. Current GBCAs can be divided into four different structural types (macrocyclic, linear, ionic, and nonionic) based on the chemistry of the chelating ligands whose primary purpose is to protect the body from dissociation of the relatively toxic Gd³⁺ ion from the ligand. This article discusses how the chemical structure influences inherent and in vivo stability toward dissociation, and how it affects important formulation properties. Although GBCAs have a lower rate of serious adverse events than iodinated contrast agents, they still present some risk. J. Magn. Reson.

Using Interrupted Time Series Design to Analyze Changes in Hand, Foot, and Mouth Disease Incidence during the Declining Incidence Periods of 2008-2010 in China

ObjectiveTo identify patterns of hand, foot and mouth disease (HFMD) incidence in China during declining incidence periods of 2008, 2009, and 2010.MethodsReported HFMD cases over a period of 25 months were extracted from the National Disease Reporting System (NDRS) and analyzed. An interrupted time series (ITS) technique was used to detect changes in HFMD incidence rates in terms of level and slope between declining incidence periods of the three years.ResultsOver 3.58 million HFMD cases younger than 5 years were reported to the NDRS between May 1, 2008, and May 31, 2011. Males comprised 63.4% of the cases. ITS analyses demonstrated a significant increase in incidence rate level (P<0.0001) when comparing the current period with the previous period. There were significant changes in declining slopes when comparing 2010 to 2009, and 2010 to 2008 (all P<0.005), but not 2009 to 2008.ConclusionIncremental changes in incidence rate level during the declining incidence periods of 2009 and 2010 can potentially be attributed to a few factors. The more steeply declining slope in 2010 compared with previous years could be ascribed to the implementation of more effective interventions and preventive strategies in 2010. Further investigation is required to examine this possibility.
