动脉栓塞对骨盆肿瘤手术疗效的影响

[目的]探讨供血动脉栓塞对骨盆肿瘤手术疗效的影响。[方法]本组16例，脊索瘤7例，骨巨细胞瘤3例，骨转移瘤3例，骨肉瘤2例，神经纤维瘤1例。术前1d行肿瘤血管造影并用明胶海绵进行供血动脉栓塞。与对照组（结扎双侧髂内动脉骨盆肿瘤切除术）比较，观察其对术中出血量、手术时间、住院时间、术后下床时间、伤口愈合时间及术后各种功能恢复的影响。[结果]骨盆肿瘤切除术前肿瘤供血动脉栓塞与结扎双侧髂内动脉比较，除术中出血量外（P〉0．05），手术、住院、术后下床及伤口愈合时间在统计学上均有非常显著性差异（P〈0．001），而且结扎双侧髂内动脉可能对患者的性功能、排便功能等存在着不良的影响。[结论]肿瘤供血动脉栓塞骨盆肿瘤切除术可大大缩短手术、住院、术后下床、伤口愈合时间，且能更好地保护盆腔内外各组织器官的血运，从而避免其功能的损害。     

上肢骨肿瘤切除后的自体骨移植重建

目的探讨应用自体骨移植对上肢骨肿瘤切除后的骨缺损修复重建的效果。方法1998年8月～2004年3月，收治上肢骨肿瘤切除后的骨缺损16例。男8例，女8例。年龄7～45岁。经病理确诊，肱骨近端尤文肉瘤和骨肉瘤各1例；肱骨远端尤文肉瘤2例；桡骨远端骨巨细胞瘤8例，高分化软骨肉瘤2例，恶性纤维组织细胞瘤和骨肉瘤各1例。2例肱骨近端肿瘤行自体锁骨代肱骨；2例肱骨远端肿瘤行自体腓骨代肱骨；12例桡骨远端肿瘤中，1例行自体髂骨移植，11例行自体腓骨代桡骨进行重建。采用MSTS系统进行术后功能评价。结果2例肱骨近端自体锁骨移植患者分别随访36个月和12个月，术后保持部分肩关节前屈和后伸功能，但外展功能丧失；MSTS评分分别为23分和22分。2例肱骨远端自体腓骨移植患者分别随访4个月和6个月，肘关节功能良好，移植骨连接处已经出现骨愈合；MSTS功能评分分别为24分和19分。12例桡骨远端自体骨移植患者中11例随访6～75个月，功能良好，无明显并发症；1例髂骨植骨的桡骨远端骨巨细胞瘤术后3个月移植骨完全愈合，至今随访75个月，肿瘤无复发。MSTS功能评分18~27分，平均22．6分。结论自体骨移植在上肢骨肿瘤切除后骨缺损的重建，尤其是儿童的骨缺损重建中，是一种较好的方法。     

Development of autoimmune hepatitis in primary biliary cirrhosis.

AIM/BACKGROUND: Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease of unknown aetiology. Up to 10% of patients with typical features of PBC will have additional features of autoimmune hepatitis (AIH). A subset, however, have no such features but go on to develop a 'sequential' AIH overlap syndrome. Objectives: Describe our experience with eight patients who developed AIH after the diagnosis of PBC was made. METHODS: We reviewed the charts of all PBC patients over a 9-year period (from 1996 to 2005). Only PBC patients with no features of AIH were included. RESULTS: There were 1476 patients with PBC. Of these, eight patients developed features of AIH overlap syndrome based on biochemical and histological parameters. Treatment included prednisone and azathioprine for 24 or more months. The majority of patients remained on ursodeoxycholic acid (UDCA) throughout treatment. Response to therapy was defined by improvement in enzymes, and was rapid for all patients. One patient was able to discontinue treatment with prednisone and azathioprine, while seven have continued on therapy to date. CONCLUSIONS: A 'sequential' overlap syndrome of AIH with PBC can occur. Treatment with prednisone and azathioprine may lead to a rapid improvement in aminotransferase levels.     

Ureteral carcinoid tumor

Most ureteral tumors are transitional cell neoplasms. Neuroendocrine tumors of the genitourinary tract are extremely rare. To our knowledge, only one ureteral carcinoid tumor has been reported before. We report a second case of ureteral carcinoid tumor found in a 70-year-old female.     

全程分期式健康教育对Miles术后患者生活质量的影响

目的探讨全程分期式健康教育对Miles术患者生活质量的影响.方法将80例行Miles术的直肠癌患者随机分为观察组与对照组各40例.观察组采用全程分期式健康教育,对照组采用传统的手术前后宣教.两组均在出院前,出院后1、3、6个月发放Miles术患者生活质量问卷,在出院前发放护理工作满意度调查表进行调查.结果观察组出院前自理能力、造口情况、心理状况及护理工作满意度显著优于对照组(P＜0.05,P＜0.01),出院时间显著缩短(P＜0.05);出院后观察组自理能力、造口情况等及生活质量总分均显著优于对照组(P＜0.05,P＜0.01).结论全程分期式健康教育能有效提高Miles术患者的近期和远期生活质量.     

骶骨肿瘤的分区切除与重建方式的选择

目的：探讨对骶骨肿瘤按其发生部位进行分区切除，选择相应重建方式的方法及疗效。方法：1988年2月-2005年1月手术治疗43例骶骨肿瘤患者，按肿瘤侵及部位（即上段骶骨、骶髂关节及骶髂关节水平向外的髂骨是否被破坏）对骶骨肿瘤进行分区切除并重建，相应的手术及重建方式包括单纯切除、钢针加塑形骨水泥（CPC）重建骶骨、钢板螺钉固定或骶骨螺钉固定重建骶髂关节、不同长度的Luque棒或髂骨棒加钢丝缠扎或TSRH或Isola或CGWS腰椎骨盆内固定。并给予相应的放疗与化疗。结果：术后出现脑脊液漏2例，切口感染及延期愈合3例，切口皮肤边缘坏死1例，下肢深静脉血栓形成1例，经积极处理后均治愈。随访1-17年，平均75个月，43例患者中39例（90．7％）术后疼痛得到缓解，视觉模拟疼痛评分由术前平均8．5分降低到术后3.4分（P〈0．01）。14例有神经功能损害的患者中，11例术后症状改善，3例无改善。20例行自体和或异体植骨的患者术后1年16例获得骨性融合。3例脊索瘤、3例恶性纤维组织细胞瘤和4例骨巨细胞瘤患者于术后1年因复发而进行1次或多次手术，其中有5例和1例骨髓瘤、1例转移癌患者于术后17-50个月因肺部和全身转移死亡。发生断棒2例，均再次手术更换断棒。结论：按肿瘤部位进行分区切除，选择相应的重建方式，达到尽可能广泛切除肿瘤组织和维持脊柱及骨盆稳定性的目的．是取得良好疗效的重要保证。     

A profile of invasive cutaneous malignant melanoma in Malta: 1993–2002

BACKGROUND: The incidence of malignant melanoma of the skin has risen in every part of the world where reliable cancer registration data are found. OBJECTIVE: Our study aims to describe the changing incidence of and survival from invasive cutaneous malignant melanoma in Malta, by analysing the data from the 211 cases that were registered at the Malta National Cancer Registry between 1993 and 2002. RESULTS: The age standardized incidence rates for invasive cutaneous malignant melanoma rose from 3.7 per 100,000 population per year for males and 5.1 for females in the first 5-year period, to 8.0 per 100,000 population per year for males and 5.9 for females in the second 5-year period. In both sexes, numbers of thin (< or = 1.0 mm) invasive melanomas increased significantly between 1993 and 2002; males also registered a significant increase in intermediate-thickness (1.01-4.0 mm) melanomas. The increase in numbers of thin and intermediate-thickness melanomas between the two 5-year periods was greatest in patients aged 60 years and over. The overall absolute 5-year survival rate for the first period was 74% and for the second period 92%. CONCLUSION: Numbers of reported cases of invasive cutaneous malignant melanoma in Malta have more than doubled during the 10-year study period. This is mostly due to a marked rise in the diagnosis of thin melanomas in both sexes, occurring mainly in patients aged 60 years and over. As thin melanomas are of low metastasizing potential, this has resulted in an increase in survival between the two 5-year study periods.     

不同输血方式对肺鳞癌患者围术期TNF—α和IL—lO的影响

[目的]探讨同种输血和自体输血对肺鳞癌患者围术期肿瘤坏死因子-α(TNF-α)和白细胞介素—10(IL—10)的影响和相互关系。[方法]2001年1月至2003年1月对31例肺鳞癌患者行肺癌根治术，将其分为两组，同种输血组(A组)17例，自体输血组14例(B组)。测定两组围术期血清中TNF-α和IL—10的浓度。[结果]A组输血后d1与输血前相比血清中TNF-α、IL-10浓度增高，以IL—10变化尤为明显，输血后d5TNF-α降低并接近输血前的水平，明显低于B组，IL—10仍明显高于输血前的水平。B组中不同时问IL—10无显著变化，TNF-α于ds明显高于输血前。[结论]肺鳞癌患者围术期同种输血后血清中TNF-α降低与IL—10升高有关，IL—10升高可能是同种输血后免疫抑制的重要原因。自体输血可减轻或去除这一作用。     

抑癌基因KLF-6和APC在结直肠癌组织中的表达及临床意义

目的 研究抑癌基因KLF-6和APC在结直肠癌中的表达规律及其临床意义。方法 应用RT-PCR和免疫组织化学法对32例结直肠癌组织和正常黏膜组织中KLF-6和APC基因mRNA及蛋白的表达进行检测和分析。结果 KLF-6与APC的mRNA阳性表达率在结直肠癌组织中分别为37、5％和34，3％，明显低于正常结直肠黏膜组织的96．9％和93．8％（P〈0．05）。KLF-6与APC的免疫组化染色阳性表达率在结直肠癌组织中分别为28．1％和25．0％，明显低于正常结直肠黏膜组织的81．3％和84．4％（P〈0．05）。KLF-6与APC在结直肠癌中的表达存在相关性（P〈0．05），并与肿瘤组织的分化程度、浸润深度、淋巴结转移及临床分期均有明显相关性（P〈0．05）。结论 抑癌基因KLF-6和APC的低表达可能与结直肠癌的发生、发展、转移及预后有关，且两者存在相关性。     

原发性肾上腺皮质癌的诊治分析

目的总结和提高原发性肾上腺皮质癌的诊治水平。方法回顾分析16例肾上腺皮质癌患者的临床资料。根据其临床症状、内分泌功能测定、影像学特点做出诊断，手术治疗并随访。结果16例患者中，内分泌功能紊乱者8例，以库欣征、性征异常、醛固酮增多症为主。超声、CT、MRI测定肿瘤直径为4．8～19．5cm，平均7．8cm。3例有远处转移。行根治性切除术13例，侵及同侧肾脏者做肾和肾上腙切除术2例，肾上腺肿瘤并腔静脉癌栓切除2例，腔静脉部分切除1例。病理结果：Ⅰ其耳2例，Ⅱ期8例，Ⅲ期3例，Ⅳ期3例。随访3-62个月，手术2年以上的11例患者中有6例仍存活，但1例肺转移，1例骨转移；死亡5例，平均存活26个月。结论肾上腺皮质癌患者预后差。影像学检查结合临床症状是早期诊断的关键，根治性手术是惟一有效的治疗方法。
