人体肺组织中镍和铬的生物监测

人体肺组织中镍和铬的生物监测Ｈａｎｓ－Ｊｕｒｇｅｎ，ｅｔａｌ．职业接触镍和铬及其某些化合物不仅可致鼻癌和副鼻窦癌，也可诱发肺癌。但因潜伏期为２０年或更长，所以在大多数情况下得不到客观的接触数据，以致确切地评价病因关系也很困难。最近的调查表明职业接触镍...     

外鼻皮肤癌手术切除及一期修复

目的探讨外鼻皮肤癌手术切除及一期修复的方法和效果。方法总结23例外鼻皮肤癌的临床资料。全部手术切除加一期修复。结果游离皮片修复12例,完全成活9例,边缘部分坏死3例,经换药等处理延期愈合。游离耳廓复合组织片修复的3例和各种皮瓣修复的8例全部成活。随访5年以上16例,3年以上7例,死亡2例,1例死于脑血管意外,1例死于心脏病。1例术后1年复发。其余病例全部存活无复发。结论外鼻皮肤癌采取手术切除和一期修复的方法是切实可行的。在彻底切除肿瘤的基础上,根据缺损的部位、大小和不同的情况,选择合适的修复材料,设计适当的修复方法,可以获得较好的效果。

Neck dissection for recurrent and persistent lymph nodes of nasopharyngeal carcinoma after radiotherapy： effect and choice

Objective:To investigate lhe best surgical mode for the patients of nasopharyngeal carcinoma with recurrent and persistent lymph nodes after radiotherapy.Methods:The dinical data of 88 patients of nasopharyngeal carcinoma with recurrent and persistent lymph nodes after radiotherapy were analyzed retrospectively.The levets of involved lymph nodes and the relationship among the levels were analyzed;the survival rate and recurrent rate of the surgical modes including radical neck dissection(RND),modified radical neck dissection(MRND),selective neck dissection(SND),and lymph node resection(LNR)were analyzed;the role of postoperative radiotherapy was evaluated.Results:(1)The recurrent and persistent lymph nodes mainly located in level Ⅱ(55.6%and 58.6%,respectively),next was level Ⅲ and rarely in level Ⅳ.Ⅴand Ⅰ,but the number of levels Ⅳ,Ⅴ and Ⅰ with cencer-bearing lymph nodes was relatively more tban that of clinical measurement.(2)Patients with lymph nodes involved in level Ⅲ and Ⅳ.usually,have other levels involved simultaneously;the percentages were 63.6%and 88.9%,respectively.However,the lymph nodes in level Ⅱ and Ⅴ were mainly isolated.(3)The 5-year survival rate and recur-rent rate of the whole group were 42.77%and 22.7%,respectively.(4)The 5-year survival rates of RND,MRND.SND,and LMR groups were 39.75%,60.00%,37.87%,and 44.10%,respectively;the differences were insignificant(Log-rank:1.0,P=0.8011):the recurrent rate between the extensive and local surgery groups were insignificant(X2=0.470,P=0.493).(5) The 5-year survival rates of the patients with and without postoperative radiotherapy were 39.06% and 45.26%.respectively;the difference was insignificant (Log-rank=0.06.P=0.8138).Conclusion:The extensive surgery was recommended when the recurrent and persistent lymph nodes were more than one level jnvolved or very large or immovable,otherwise,the SND should be performed and postoperative radiotherapy was important compensation if necessary.     

生命的计划

老张、老李因为鼻子不舒服，同时住进了医院。在等待化验结果期间，老张说，如果是癌，立即去旅行，并首先去拉萨。老李也有差不多同样的表示。不久，结果出来，老张得的是鼻癌，老李长的是鼻息肉。于是老张离开了医院，老李住了下来。
