病变

We must know the priniciple that Pap is a screening test. If Pap interpretation is AGC or ascus and tissue bx is negative, it does not mean that you have a wrong diagnosis on Pap. Remember that most women with AGC or ASCUS Pap will be no cervical lesions in tissue biopsy.

通过以上这几次回帖其实给我的教训很深刻，让我脑子不停的想起老师的话："诊断恶性病变的时候一定要排除类似的良性病变；在诊断良性病变的时候一定要排除类似的恶性病变"。

Left circumflex arteries,8 right coronary artery .

有 3 0例 3 9支冠状动脉显示程度不同的狭窄，其中左主干病变 2支，左前降支及分支病变 2 0支，回旋支病变 9支，右冠状动脉病变 8支。

Results:50 patients with lesions associated with anterior descending artery was 35,and the right coronary artery 19,circumflex 10.26 patients with single-vessel disease,18 patients with double-vessel disease,and three lesions 6,the survival rate of PCI is 98%.we follow up from 6 to 40 months after surgery,Chest pain occurred again in 7 patients, 3 patients performed PCI, and 1 case had stent obstruction,1 case died of AMI.

结果：50例病变相关动脉为前降支35处，右冠状动脉19处，回旋支10处。单支病变26例，双支病变18例，三支病变6例；PCI成功率98%；术后随访6～40个月，7例再次出现胸痛发作，3例患者行PCI术，其中1例为原有支架闭塞；急性心肌梗死死亡1例，为心肌梗死后心功能衰竭。

HP positive groups was compared with HP negative groups in gastric mucosal lesions, expression of P16 in HP positive groups was lower than that in HP negative (P＜0.01), expression of CD44V6, PCNA and C-met in HP positive groups were all higher than those in negative groups (P＜0.01). Expression of P16 was negative correlated with expression of CD44V6, PCNA and C-met in HP-infected gastric mucosal lesions (r〓=-0.6971, P＜0.01; r〓=-0.4811, P＜0.01; r〓=-0.6075, P＜0.01); Expression of CD44V6 were positive correlated with expression of C-met and PCNA (r〓=0.6550, P＜0.01; r〓=0.4977, P＜0.01). Selenium level in HP-infected gastric mucosal was Significantly higher than normal and the level will fall with deteriorism of gastric mucosal lesions.

临床标本研究结果表明：在系列胃粘膜病变中，P16表达HP阳性标本显著低于HP阴性标本（P＜0.01）；CD44V6、C-met、PCNA表达HP阳性标本均显著高于阴性标本（P＜0.01）；在HP感染的胃粘膜病变组织中，P16表达与CD44V6、C-met、PCNA表达均呈负相关（r〓=-0.697l，P＜0.01；r〓=-0.4811，P＜0.01；r〓=-0.6075，P＜0.01）；CD44V6表达与C-met、PCNA表达相互呈正相关（r〓=0.6550，P＜0.01；r〓=0.4977，P＜0.01）；HP感染的胃粘膜病变组织硒含量明显升高，并随胃粘膜病变程度加重相对降低，但高于正常组织；硒含量分别与CD44V6、C-met、PCNA表达阳性率呈负相关（P＜0.05），而与P16表达阳性率呈正相关（P＜0.05）。

There were no difference in the appearance of parotid sialography in the 0 and the ≥60 age group. Conclusions: The pathological changes of the parotid duct in SS could be divided into 6 stages, ie, normal appearance of parotid duct, early stage of pathological changes of terminal ductules, late stage of pathological changes of terminal ductules, pathological changes of parotid trunk and branches of parotid duct, early-stage of gland atrophy, late-stage of gland atrophy.

60岁和≥60岁两组SS患者的腮腺造影表现经统计学处理无显著性差异、结论：SS患者腮腺导管病变可以分为腮腺导管形态正常期、末梢导管病变早期、末梢导管病变晚期、分支导管及主导管病变期、腺体萎缩早期及腺体萎缩晚期等6期。

Risk factors of ARAS existing are smoking、coronary disease、Peripheral vascular disease、hyperlipidemia、renal insufficience、hypertesion, and independent predictors are hyperlipidemia、smoking、coronary artery disease and Peripheral vascular disease.

2预示ARAS存在的高危因素有冠脉病变、外周血管病变、吸烟、高血脂、肾功能不全、高血压，其独立预测因素为高血脂、冠脉病变、吸烟、外周血管病变。

To master basic and complex pathological change of atherosclerosis; the characteristic of coronary AS, brain AS and nephridium

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。
