Use of YAG laser combined with mucosal suturing for the treatment of polypoid vocal cord]

To improve low-pitched voices in cases with polypoid vocal cords, YAG laser irradiation combined with a mucosal suturing technique was attempted in 9 female cases with severe polypoid changes in their vocal cords. A YAG laser beam (5 to 10 W) was used to irradiate the upper surface of the polypoid vocal cord. The polypoid content of the cord was gradually coagulated, and the free edge of the cord appeared to slide up toward the burned area. The polypoid content was then removed and squeezed through an open wound made in the burned area using a conventional method. Bleeding was successfully controlled using the laser. After the excessive mucosal margin was trimmed and the contour of the vocal cord was adjusted, the wound was closed by 7-0 monofilament absorbable suture. Suturing was relatively easy because the mucosal edge was also coagulated. Postoperative evaluations of voice quality revealed an improvement in the GRBAS scale of voice quality as well as an elevation in voice pitch and an upwards shift in the voice range in all cases.     

p27kip1及p53基因蛋白与恶性卵巢上皮性肿瘤预后的关系

目的　探讨 p2 7kip1和 p5 3基因蛋白在恶性卵巢上皮性肿瘤中的表达及其与预后的关系。 方法　1992年 11月至 1999年 12月应用免疫组化检测 5 6例恶性卵巢上皮性肿瘤石蜡切片中 p2 7kip1和p5 3基因蛋白表达情况 ,并应用Kaplan -Mier法及多变量Cox比例风险回归模型分析患者预后。 结果　 5 6例恶性卵巢上皮性肿瘤患者的 p2 7kip1基因蛋白表达率为 4 1 1% ;p5 3基因蛋白表达率为 4 8 2 % ,两种基因蛋白表达比较 ,差异无显著性 (P >0 0 5 )。p2 7kip1及 p5 3基因蛋白表达与肿瘤的病理分级有关 ( P <0 0 5 ) ,与其他临床病理特征无关。单因素分析 :p2 7kip1及 p5 3基因蛋白表达与患者的中位生存时间、生存曲线各时点生存率密切相关。 结论　p2 7kip1基因蛋白表达对恶性卵巢上皮性肿瘤的预后有显著影响 ,而 p5 3基因蛋白表达与预后关系不显著     

外阴癌中HPV感染与p53、MDM2表达的关系

目的 :探讨HPV6/ 11、16/ 18在外阴癌组织中的感染情况及与p5 3、MDM2蛋白表达的关系。方法 :用原位杂交法 (ISH)检测HPV6/ 11、16/ 18在 30例外阴癌、2 1例外阴上皮内瘤变 (VIN)及 10例外阴正常皮肤组织中的表达。同时用免疫组化SP法检测p5 3、MDM2蛋白的表达。结果 :HPV6/ 11、16/ 18在外阴癌、VIN中的阳性表达率分别为 60 % (18/30 )、33.33% (10 / 30 ) ,4 2 .86% (9/ 2 1)、2 8.5 7% (6/ 2 1) ,正常对照组没有表达。p5 3、MDM2蛋白在外阴癌、VIN、正常对照组中的阳性表达率分别为 63.33% (19/ 30 )、4 0 .0 0 % (12 / 30 ) ,4 7.62 %(10 / 2 1)、5 2 .38% (11/ 2 1) ,0 % (0 / 10 )、0 % (0 / 10 )。HPV6/ 11的表达在外阴癌组、VIN组与正常组差异有显著性 (P <0 .0 5 ) ,外阴癌组HPV16/ 18表达与正常组差异有显著性 (P <0 .0 5 )。外阴病变各组p5 3、MDM2与正常组差异有显著性 (P <0 .0 5 )。结论 :HPV6/ 11、HPV16/ 18、p5 3、MDM2蛋白在外阴组织的不同病变中表达均差异有显著性 ,在外阴癌的发生发展中HPV感染、p5 3突变和MDM2表达可能起一定的作用     

肾恶性横纹肌样瘤临床病理分析及超微结构观察

目的:探讨肾恶性横纹肌样瘤(MRTK)的临床病理表现及超微结构特点。方法:用光镜、免疫组化及电镜等方法观察其病理组织学特点、免疫组化表达及超微结构。结果:光镜的典型特点是肿瘤细胞弥漫性排列,呈圆形、椭圆形及不规则形,胞质丰富,嗜酸性,部分胞质内可见透明状小体,细胞核圆形或椭圆形,核膜厚,核仁清楚,有的细胞核呈空泡状。部分核偏向一侧似浆细胞样。细胞内外见红染的包涵体。免疫组化显示肿瘤可表达多种抗原。电镜观察特异性表现是胞质内见中间丝及圆形不规则形纤维状或轮状小体。结论:肿瘤细胞弥漫排列呈浆细胞样,免疫组化多方向表达,可向神经性、上皮性、肌性等方向分化。电镜下胞质内中间丝及纤维轮状小体是特异性诊断标志。

A morphological study of the human epipharyngeal mucosa

The epipharynx lies between the nasal cavity and oropharynx. The mucosa of the epithelium in the human epipharynx is composed of ciliated epithelium as part of the respiratory tract, squamous epithelium as representative of the digestive system and transitional epithelium. Previous studies by Ali have shown that transitional epithelium is present in a boundary line between the epipharynx and oropharynx, with numerous islets of the epithelium also located in the lateral and dorsal walls accompanied with a patchy distribution of the ciliated and squamous epithelium. Mechanical irritation caused by the anatomical properties of the epipharynx is thought to be responsible for the morphological findings present. We studied the distribution of the three different types of epithelia in the epipharynx in ten autopsy cases. Our data revealed that they showed mosaic or an “island-like” distribution on the epipharyngeal wall and their patterns of distribution were variable in each individual.
