小肝癌的外科治疗（附手术切除103例临床分析）

9年间我科共对223例肝癌病人完成各种类型的肝切除术．其中肿瘤直径≤5cm者103例．包括≤3cm者28例．3．1～5cm者75例。其年龄范围为26～76岁，平均为51．3±10．4岁．男93例，女10例。HBsAg( )75例．肝硬变88例。行联合肝段切除15例．肝段切除20例．局部肝切除68例。病理类型为肝细胞癌100例，胆管细胞癌3例。结果：103例小肝癌TNM分期为Ⅰ期6例、Ⅱ期37例、Ⅲ期53例、ⅣA期5例和ⅣB期2例。其中肝细胞癌99例，高分化21例、中分化65例和低分化13例。手术死亡率为0．97％，术后1、3、5年生存率为92．7％、72．5％、54．3％。高、中、低分化者术后5年生存率分别为79．6％、49．9％和41，1％。术后1、3、5年复发(转移)率为12，8％，40，7％、71．5％。结论刊、肝癌具有与太肝癌一样的肝病背景．综合多种因素选择肝癌手术方式．合理掌握肝切除量是提高手术切除率、减少术后并发症的重要途径。小肝癌并不等于早期肝癌，尽管行肝癌根治性切除，远期复发和转移率与大肝癌一样高．是亟待解决的课题。     

穿心莲乙酯对大鼠心肌缺血再灌注损伤的保护作用

本实验观察了穿心莲注射液对大鼠心肌缺血再灌注损伤的影响。结果显示:穿心莲(2.5mg·kg~(-1),iv)可保护缺血再灌注心肌SOD活性(P<0.01),降低MDA含量(P<0.001),明显降低严重心律失常发生率。提示穿心莲注射液对缺血再灌注心脏具有保护作用,其抗脂质过氧化作用可能系其作用机制之一。

提高股骨干骨折合并同侧股骨颈骨折早期诊断率的前瞻性研究

Objective To evaluate a serf-designed diagnostic protoeol which can early detect a femoral neck fracture for patients with a femoral shaft fracture. Methods From September 2005 to June 2007, a self-developed protocol was used to detect an ipsilateral femoral neck fracture for all the patients with femoral shaft fracture who had sought treatment in our department. This protocol consisted of anteroposterior plain radiography of internal rotator, intraoperative fluoroscopy of the hip, a fine (2 mm) cut computed to-mographic scan through the femoral neck, postoperative anteroposterior and lateral plain radiography of the hip in the operating room prior to awakening the patient, at the time of follow-up anteroposterior and lateral plain radiography of the hip in the presence of hip pain. The diagnostic effects of the protocol were compared with those of conventional diagnosis used for all the patients with femoral shaft fracture who had sought treatment in our department from September 2003 to August 2005. A chi-square analysis comparing the protocol group (September 2005 to June 2007) and the non-protocol group (September 2003 to August 2005) was used to assess the early and delayed diagnosis rates for an associated ipsilateral femoral neck fracture. Results The earlydiagnosis rate of an associated femoral neck fracture by the protocol was 93.8%, markedly higher than that by conventional method (46.2%), with statistically significant difference (χ2 = 4.069, P =0.044). Conclu-sion In presence of a femoral shaft fracture. this protocol consisting of plain radiography of intemal rotator, intraoperative fluoroscopy of the hip, fine cut computed tomographic scan of the femoral neck, postoperative plain radiography of the hip, and follow-up plain radiography of the hip in the presence of hip pain, may sig-nificantly improve the diagnostic rate of an associated femoral neck fracture.     

PATHOGENESIS OF EXTRINSIC ALLERGIC ALVEOLITIS AND PULMONARY FIBTOSIS INDUCED BY STREPTOMYCES THERMOHYGROSCOPICUS

There were 48 strains of thermophilic actinomyces isolated from the specimens of mouldy hay and sputum of the patients suffering from farmer’s lung (FL). Streptomyces thermohygroscopicus (STHs),one strain of them, was used for this investigation. The microorganisms were injected into the lungs of rabbits and rats by thyrocrico – or tracheocentesis. The result showed that the pathological changes in the lungs including macrophage alveolitis, granuloma formation and diffuse interstitial were similar to that induced by other thermophilic actinomyces. IgG and C3 deposition in the lesions were also observed by immunofluorescence examination. Specific immunocomplexes in the sera of some animals were detected by ELISA with the STHs was possibly one of the pathogens responsible for FL in China’s countryside.

实时荧光定量RT-PCR检测肝细胞癌中删基因的表达

目的探讨PTCH基因在肝细胞癌组织中的表达及其与肝癌病理分级的关系。方法提取手术切除18例不同病理分级的人肝癌、癌旁组织和6例胆管结石手术切除的正常肝组织中的总RNA并逆转录为cDNA。应用实时荧光定量RT-PCR法观察人肝细胞癌组织与癌旁组织中PTCH基因的相对表达水平,以及观察人正常肝组织中PTCH基因的表达水平。结果PTCH在所测18例肝细胞癌组织与癌旁组织中均有表达,在6例正常肝组织中不表达，且在病理分级为Ⅰ和Ⅱ级的癌组织中PTCH的mRNA表达水平显著高于癌旁组织（P〈0．01），而在病例分级为Ⅲ级的癌组织中PTCH的mRNA表达水平显著低于癌旁组织（P=0．024）。结论随着肝癌恶性程度的增加PTCH的mRNA表达量呈递减趋势，提示PTCH可能参与了肝细胞的早期癌变过程。
