圆孔外面的观察和测量及其面积的回归方程 总被引:4,自引:0,他引:4
60具成人颅骨颅底外面的圆孔观察和测量结果表明:圆孔多呈圆形,其次是卵圆形,其它形较少见.据圆孔与翼突外侧板根部延长线的位置关系,分圆孔位置为三型.圆孔外面观的各项测值左右间均无统计学差异,但其中管性圆孔管长度个体差异较大.圆孔的面积左右比较对称者占3.33±2.34%,左>右者占65.51±6.30%,右>左者占34.48±6.30%.圆孔面积左右对称性比较,对临床诊断疾病有参考意义.其面积的回归方程可由其长、宽径乘积推算 . 相似文献

Objective: The purpose of this study was to study the clinical, imaging characters and pathological characteristics of esophageal sarcomatoid carcinoma. Methods: We reviewed 23 cases of esophageal sarcomatoid carcinoma from Janu-ary 2006 to December 2013 in four hospitals. The data of patients who were esophageal sarcomatoid carcinoma operated were retrospectively analyzed. Al cases had completed upper gastrointestinal barium images materials and 14 of these cases had completed CT images materials. Upper gastrointestinal barium images and CT imaging features include tumor location, size, shape, and strengthen, etc. The biological parameters of lesions including the express of cytokeratin AE1/AE3, 34βE12, p63, Vimentin, desmin, Actin, S-100 and Ki-67 detected by immunhistochemical UltraSensitiveTM S-P method (n=23), and the patients’ data of contrastographic picture (n=23), imaging characters of CT scan (n=14), and their relationship were studied. Results:Upper gastrointestinal barium images, CT imaging and gastrointestinal fiberscopy revealed lobulated intraluminal fil ing defect 0.4 cm to 5.7 cm × 3.5 cm × 1.3 cm (mean=3. 7 cm) in the mid (n=14), lower (n=7) and upper (n=2) intrathoracic esophagus. Among 23 cases of esophageal sarcomatoid carcinoma, 19 patients were of mushroom type, 2 patients was of ulcer type, and 2 patients were of medul a type;19 patients were pedunculated, and 4 patients were no pedunculated (2 patients was of ulcer type). The tumor surface was relatively smooth and esophageal compliance was maintained. The pathological changes of esophagus such as lightly locked, rigid wal no-manifest partly, esophageal lumens expand partly, major fil ing sublobe defect could be shown through contrast medium. Normal esophagus was no unpack obviously over pathological changes. Enhanced computed tomography showed tumors in the intrathoracic esophagus and 8 lymph nodes metastases in 3 cases. Histological y, carcinomatous and sarcomatous components coexist. Microscopical y, the tumor comprised poorly dif erentiated squamous cellcarcinoma and spindle-shaped cells resembling leiomyosarcoma. Immu-nohistochemical y, spindle-shaped sarcomatous cells displayed weekly positive reaction to cytokeratin AE1/AE3. Transitional zone was seen between sarcomatous and carcinomatous elements in 5 cases. The 17 lymph nodes metastases in 5 cases (53 lymph nodes) among 23 cases esophageal sarcomatoid carcinoma (187 lymph nodes) were observed. Conclusion:The clinical and radiologic features of esophageal sarcomatoid carcinoma overlap with those of other esophageal neoplasms. There are the radiologic imaging changes such as a large, intraluminal, polypoid mass, major fil ing sublobe defect and pedicle skin flap tumor in esophageal lumen, esophageal lumen extension partly, dissepiment rigidity wal no obviously, etc. Histological y, carcinomatous and sarcomatous components coexist and the biphasic pattern is the key diagnostic feature. However, esophageal sarcomatoid carcinoma has a more favorable prognosis than other malignant esophageal neoplasms. Immunohistochemical staining seems necessary to distinguish these lesions from other esophageal neoplasms. 相似文献

目的:探讨四边孔综合征的致伤原因及非手术治疗疗效,加强医务人员对此病的认知、诊断、预防及治疗。方法:选择2012年4月至2015年1月就诊的四边孔综合征患者7例,病程3周至半年。部队训练伤和健身训练损伤5例,家务劳动损伤2例。肩部疼痛活动受限症状为主,对症治疗效果不明显来我院。诊断明确后,采用手法、针灸、封闭、理疗等中西医结合康复治疗。结果:患者肩部症状完全或大部分消失,肩部肌力、感觉正常,肩关节功能活动正常,临床治愈,平均住院治疗21 d。结论:四边孔局部解剖的特异性及训练科目的特殊性和劳动姿势不良,导致四边孔综合征的易发生率,早期正确诊断并给予非手术综合治疗效果满意。 相似文献

两种常见缺失型α-地中海贫血快速检测技术的研究 总被引:5,自引:3,他引:5
目的:建立简便快速准确可推广使用的检测α-地中海贫血(α-Thal)右侧失型(-α^3.7)和左侧缺失型(-α^4.2)的聚合酶链反应(PCR)方法。方法:自行研究设计两组引物。优化PCR反应条件。PCR反应产物用1%琼脂糖凝胶电泳分离,溴化乙啶染色,UVP凝胶成像仪下观察记录电泳图谱。结果:运用引物A′、B′、C3进行PCR,出现1700bp扩增带表示-α^3.7,出现1900bp扩增带表示α-珠蛋白基因正常或为野生型。二条扩增带同时出现表示是-α^3.7缺失杂合子。无任何扩增带表示是是东南亚型缺失纯合子。运用引物G′、E、F′进行PCR,根据出现1580bp扩增带和1180bp扩增带可诊断为-α^4.2,还可区分杂合子与纯合子。结论:本研究设计的两组引物及优化的PCR条件,可以简便准确地检测出α-Thal标本中有无-α^4.2和-α^3.7。 相似文献
