为所应为

Surgical therapy is the first choice for the recurrent stomal ulcer with complications and BAO,MAO obviously higher,stomal resection and gastrojejunal Roux-en-y anastomosis are effective methods to treat the stomal ulcer,and conservative treatment should be chosen primarily for the patients with slightly elevated BAO,MAO.

胃部分切除术后发生吻合口溃疡的主要原因为胃酸高所致，对有明显并发症且基础胃酸、最大胃酸明显高于正常者应采取外科手术治疗，原吻合口切除、胃空肠Roux-en-y吻合是治疗吻合口溃疡的有效方法。对BAO、MAO增高不明显者可用内科治疗，效果较好。

Objective: We employed MEG to study M75 and M100 in visual evoked magnetic field, stimulated by whole and half field pattern reversal of children with anisometropic amblyopic eyes and normal eyes as control, to investigate the imposable cortical machine of anisometropic amblyopia.

中文摘要：目的：应用脑磁图(Magnetoencephalography，MEG)来研究屈光参差性弱视儿童全视野和半视野黑白棋盘格翻转刺激所产生视觉诱发磁场成分中的M75和M100，并以正常眼为对照进行分析，从而探讨屈光参差性弱视发病的中枢机制。

Contemporary voices tell us we must recognize something obscured by the legal "positivists" whose day is now over: that there is a "point of intersection between law and morals," or that what is and what ought to be are somehow indissolubly fused or inseparable, though the positivists denied it.

当代法律理论告诉我们必须认清为过时的法律实证主义者所遮蔽的事实：&法律规范和道德规范之间存在着交点，&或，实然与应然之间有着无法割裂的联系，尽管实证主义者否认这点。

In China, where the present is to a certain extent history, snapshots can be misleading; discourses should integrate different "clocks" and be attentive, behind shorter developments or even ephemeral fashions, to very slow movements, what Fernand Braudel (1902-85) called the longue duree.

我们应去除短暂发展时期（更不用说那些短命的时尚趋势）的干扰，将它们整合进历史长河中一些缓慢但关键的演变运动中进行深入分析。这也就是法国史学家、&总体史&的集大成者费尔南多。布罗代尔（Fernand Braudel，1902-1985）所强调的长时段。他把历史时间划分为&短时段&、&中时段&、&长时段&，并认为长时段才是把握和认识历史的关键。

Therefore the nonrandom distribution of 3′ end sequences of effectual primers in tomato RAPD reflected the sequence-specific structure may occur in tomato genome at flank of polymorphic regions. It is probably an attribute of tomato genomic sequence and is common in Lycopersicon.

RAPD引物3′端序列的非随机分布，反映了番茄基因组内的多态性区段侧翼具有序列的特异性，这种特异性结构应是番茄基因组序列的一种属性，这种属性为番茄属基因组所共有。

Objective To analyze the CT and MRI manifestations of oral carcinoma,and to evaluate the value of imaging technologies in the diagnosis of oral carcinoma,thus to explore the most reasonable imaging method Methods 46 cases with oral carcinoma,proved by surgery and pathology （2 lip tumors,8 carcinomas of the gingival ridge,5 carcinomas of the buccal mucosa,24 tongue carcinomas,5 carcinomas of the floor of the mouth,2 tumors of the hard palate）,were analysed retrospectively32 cases were examined with CT and 14 cases with MRIImaging presentations were compared with surgery and pathology Results Of the 46 cases with oral carcinoma,22 were ulcerative lesion of infiltrative growth,24 were masslike lesion of extruded trowthOf the 32 cases examined with CT scan,27 were detected,5 were missed,the 4 missed cases were confirmed to be superficial ulcers by surgery and pathologyOf the 10 cases with bone destruction examined with CT scan,8 were manifested,2 were missedAnd of the 14 cases with MRI scan,all 14 were detected Conclusion CT and MRI scan are valuable for diagnosis of oral carcinomasThey can manifest the morphology and size of primary tumor,contiguous structures,bone invasion and cervical lymph node metastasisMRI is the optimal imaging method for superficial ulcerative lesion of infiltratibe growth

徐 锋，罗德红，唐威，欧阳汉，周纯武目的分析口腔癌的CT及MRI表现，评价影像检查在口腔癌诊断中的应用价值，探索合理的影像学检查方法。方法回顾性分析经手术及病理证实的口腔癌46例（唇癌2例，牙龈癌8例，颊黏膜癌5例，舌癌24例，口底癌5例，硬腭癌2例），其中32例行CT扫描，14例行MRI扫描，将影像表现与手术所见及病理结果进行对照分析。结果 46例口腔癌中，呈浸润性生长的溃疡型病变22例，外生性生长的肿物型病变24例。CT扫描32例，明确显示病变27例，遗漏病变5例，其中4例为表浅溃疡型病变。CT扫描病例中，10例有骨质侵犯，CT扫描准确评价8例，遗漏2例。MRI扫描14例，均准确评价肿瘤及其与周围结构的关系。结论 CT、MRI对口腔癌原发肿瘤的形态、大小、周围结构侵犯、颈部淋巴结转移的评价有重要价值。对于较小及呈浸润性生长的表浅溃疡型肿瘤，CT扫描尤其是CT平扫难以准确显示，应首选MRI。

The results showed that monocarboxylic acid stearic acid played a role of surfactant, and the product was still orthorhombic Ce2O(CO3)2·H2O with a high crystallization degree. In turn, duality-carboxylic acid tartaric acid...

实验结果表明在尿素及硝酸铈的混合溶液中分别加入一元羧酸硬脂酸，二元羧酸酒石酸和三元羧酸柠檬酸时，一元羧酸硬脂酸在混合溶液中只起表面活性剂的作用，其产物为斜方晶系的单晶Ce2O(CO3)2.H2O微粉，且表面活性剂硬脂酸的加入使得晶体的晶化程度明显提高；而二元羧酸酒石酸与三元羧酸柠檬酸在均相反应中则起螯合剂的作用，分别与Ce3+形成螯合物酒石酸铈和柠檬酸铈，这些结果的造成是由于其反应机理的不同所导致的。
