尿道下裂成形术后并发症的临床分析

Objectives To study and analyze the cauge,rate and treatment for complications of hypospadi - as repair operations.Methods In the past 3 years,there were 19 patients with complications of hypospedias repair for 117 cases single - stage urethmplasty.The ages were from 1.5 to 24 years old,the mean Was 4.6.The classifica - tions were glans of penis 10,body of penis 5,serious hypospedias 4,includingpenoscrota,scrotal andperineal.The lengths of new urethras were from 1.2 to 4.4 cm,the mean was 2.6 cm.Results The rate of complications was 15.9%for 1～3 years following survey.There were urethral fistulas 11 cases(57.9%),urethral strictures 4(21.1%),diverticulumsl(5.3%),withdrawal of meatus 1(5.3%),chordees 1(5.3%),seriouS abnomal apperance of penis 1 cases(5.3%).The rate of urethral fistulas was the first and urethral stricture the second,they were higher than other complications signiflcantly(P相似文献

蕲蛇酶减轻大鼠局灶性脑缺血再灌注损伤的实验研究(Ⅱ)

目的 从病理形态学观察蕲蛇酶对大鼠局灶性脑缺血再灌注损伤的保护作用并探讨其机制。方法 采用线栓法制备大鼠大脑中动脉栓塞后再灌注模型，光镜及电镜观察缺血3h恢复血流再灌24h后脑组织形态学变化。TTC染色观察脑梗死面积，免疫组织化学方法检测脑组织碱性成纤维细胞生长因子（bFGF）的表达。用药组分别在缺血即刻或再灌即刻静脉给予不同剂量的蕲蛇酶，观察比较模型组和蕲蛇酶所有给药组之间上述指标的变化。结果 缺血即刻给蕲蛇酶4U／kg组较再灌即刻给蕲蛇酶同剂量组显著减小梗死灶（P〈0．001），减轻脑组织病理改变，并使脑组织中bFGF蛋白表达明显增多。结论 蕲蛇酶对脑缺血再灌注损伤的神经保护作用可能与脑组织中bFGF表达增高有关；提示该药早期使用更为有效。     

侵袭性骨肿瘤骨质破坏的形态学观察和图像分析

将整个骨肿瘤制成组织大切片，通过光镜观察和图像分析，对１０例侵袭性骨肿瘤的骨质破坏机制进行研究，其中骨肉瘤２例，纤维肉瘤３例，骨巨细胞瘤、软骨母细胞瘤、淋巴瘤、骨髓瘤和骨旁骨肉瘤各１例。结果表明：肿瘤中心区的骨质破坏程度明显高于肿瘤边缘区和外围区，同时未见到破骨细胞被激活致溶骨增强的现象，这些都支持侵袭性骨肿瘤的骨质破坏机制，主要是肿瘤细胞直接溶骨的学说。根据我们的观察，骨肿瘤组织破坏骨质有三种方式：（１）肿瘤细胞与骨质直接接触，溶解骨质。（２）肿瘤组织侵入哈氏管，引起管腔扩大，管壁破坏。（３）肿瘤组织直接压迫致骨皮质萎缩变薄，骨小粱变纤细。结果还表明：侵袭程度不同的骨肿瘤，其骨质破坏的主要方式也不同。侵袭性较高的骨肉瘤、纤维肉瘤和淋巴瘤，其肿瘤中心区和边缘区的哈氏管内较多见肿瘤组织的浸润，提示这些肿瘤可能首先通过哈氏管进行扩散的；侵袭性较低的骨巨细胞瘤和软骨母细胞瘤则未见到这种现象，而以局部骨质破坏和压迫萎缩为主；骨旁骨肉瘤虽然也出现哈氏管浸润，但管壁的破坏程度明显比骨肉瘤轻。
