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

中华硕博网核心提示：徐锋，罗德红，唐威，欧阳汉，周纯武关键词：口腔肿瘤目的分析口腔癌的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四周结构的关系。结论 CT、MRI对口腔癌原发肿瘤的形态、大小、四周结构侵犯、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。

RELAP5/MOD2/RMA is a best estimated transient simulation code which adopted the nonhomogenous and non-equilibrium two-liquid model with six governing equations to describe the thermalhydraulic phenomena of mass, momentum, and energy for both the liquid and vapor phase respectively, which eliminates the constraint of one saturated phase existed in the previous versions.

RELAP5/MOD2/RMA程序是一个最佳估算瞬态分析程序，采用六方程描述非均相、非平衡态的液相及汽相的质量、动量、及能量的热工水力现象，消除了先前版本中两相流体必有一相为饱和态的限制，被广泛用于小破口失水事故及其他瞬态的分析与计算中。

The same procedure was carried out 14 days later. Results The temperature of inferior segment of esophagus was significantly increased at 60min. The temperature of physic liquor was significant higher than that of perfusion. The temperature of perfusion was becoming significantly increased at 5min (P.05). The WBC, PLT, ALT, AST, Cr and CO2CP of preoperative and postoperative had no significant changes. Only lightly peritoneum dropsy and infiltrate slight phlegmasia were observed postoperatively and 14 days later. There were no significant differences among groups.

结果 在60min时食道下段温度显著升高，灌注温度明显高于抽取温度，抽取温度5min时开始升高(P.05)；各组术前和术后WBC、PLT、ALT、AST、Cr和CO2CP无明显变化，组间比较也无明显差异；术后和术后2wk腹膜均见轻度水肿、少量的炎细胞浸润；吻合口见黏膜层有小溃疡形成，表面有渗出，组间无明显差异。

Methods Take Millard law as basis,piece of contrapuntal suture C fixed point being designed,rotating,full muscle of mouth wheel sneaking under the piece of skin parting for and will be located in nose pillaret,the wing of nose place in A,B is away from breaking,revolution cotton-padded mattress style sews the ridge taking form up,to be good for lip external shape formation and functional recovering.
