The objective of this work is to investigate the expressions of CCR7 and VEGF-D protein in non small cell lung cancer and the relationship of their expressions with LVD and lymph node metastasis, and through CCR7 gene transfection to study its impact on VEGF-D expression, and to reveal the molecular mechanism of CCR7-induced lymphangiogenesis and lymphy node metastasis in NSCLC.

本文通过研究CCR7、VEGF-D蛋白在非小细胞肺癌组织中表达及其与淋巴管密度、淋巴结转移之间关系，并通过转染CCR7基因研究其对VEGF-D调控机制，目的揭示CCR7诱导肺癌组织淋巴管形成促进转移的分子机制。

CCR7 could induce lymphangiogenesis and promote lymphy node metastasis by upregulating the expression of VEGF-D in NSCLC.

CCR7可通过上调VEGF-D表达诱导肺癌组织淋巴管形成、促进淋巴结转移。

Results Mottling and patchy infiltrats were observed in 42 patients, irregular shape cavities in 41 patients, 28 patients had satellity lesions, 8 had fibrotic stripes, 10 had mottling califacations, 2 had lymphy node enlargement.

结果得到42例均见斑片状高密度灶影，其中41例不规则空洞影，4例与支气管相通；28例卫星灶影，8例纤维索条影，1例仅见小斑片状影伴卫星灶影，10例见斑点状钙化影，2例淋巴结肿大等。

The expression of VEGF was observed by using image analysis and the secretion of VEGF by macrophagus was tested by using immunohistochemistry method.

结果：在口腔鳞癌中，VEGF的表达和微血管计数、巨噬细胞计数呈现正相关(P.05)；VEGF的表达、巨噬细胞的浸润和肿瘤的淋巴结转移有关(P.05)，口腔癌浸润的巨噬细胞中有29%~10%的细胞内有VEGF的表达。

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。
