胸腔镜辅助小切口手术诊治肺周围型结节

目的探讨胸腔镜辅助小切口手术在诊断和治疗肺周围型结节病变中的临床应用价值。方法胸腔镜辅助小切口手术诊治肺周围型结节55例，其中单发结节54例，多发结节1例。肺楔形切除术23例；肺叶切除联合淋巴结清扫治疗原发性肺癌32例，采用常规开胸手术器械及胸腔镜用器械切除肺叶，自制淋巴结摘除钳完成淋巴结清扫。结果55例均在胸腔镜下完成手术。手术时间35～180min，平均109min，术中出血量50～400ml，平均122min。均未输血，1例术后漏气术后32d出院，1例切口延迟愈合，术后19d出院，余53例术后住院4～11d，平均8．3d。无严重并发症。术后病理：良性病变15例，原发性肺癌38例，非典型性腺瘤样增生1例，转移性肺癌1例。良性病变行肺楔形切除术，32例原发性肺癌行解剖学肺叶切除联合淋巴结清扫，4例肺癌胸膜广泛播散未手术处理，2例肺癌因肺功能差行姑息性肺楔形切除。结论胸腔镜辅助小切口手术有助于明确诊断肺周围型结节病变，治疗临床早期原发性肺癌的长期疗效有待随访观察。     

经尿道等离子双极电切术和TURP治疗BPH术后阴茎勃起功能障碍的比较

目的探讨经尿道等离子双极电切术(PKRP)治疗良性前列腺增生(BPH)术后对阴茎勃起功能的影响。方法PKRP、经尿道前列腺电切术(TURP)治疗BPH各95例,评价其术后1个月、3个月及1年阴茎勃起功能。结果PKRP、TURP术后1个月、3个月及1年阴茎勃起功能障碍(ED)发生率分别是3．2％、2．1％、2．1％和13．7％、10．5％、9．5％。结论PKRP术后ED发生率比TURP低,是一种对阴茎勃起功能较为安全的治疗良性前列腺增生的方法。     

诱导型一氧化氮合酶在前列腺增生组织中表达的研究

目的：探讨诱导型一氧化氮合酶(iNOS)与前列腺增生(BPH)病理生理变化的关系。方法:用免疫组化法检测10例正常和30例有膀胱出口梗阻的BPH患者膀胱和前列腺组织中iNOS的表达。结果：BPH组前列腺组织中iNOS呈阳性染色，主要分布于前列腺的上皮细胞及上皮下组织中，间质平滑肌组织中均为阴性；对照组的膀胱壁、膀胱颈部和前列腺组织中均无iNOS阳性染色。结论：iNOS仅在BPH患者前列腺组织中有特异性表达，提示它参与了前列腺增生的病理生理过程。     

前列腺癌组织中性激素受体表达的分析

目的:定性分析雄激素受体(AR)、雌激素受体(ER)、孕激素受体(PR)在良性前列腺增生(BPH)和前列腺癌(PCa)组织中的阳性表达,为激素治疗PCa和预后判断提供一定的依据。方法:采用免疫组化DAKO Envision二步法,分析30例BPH与32例PCa标本中AR、ER、PR的阳性表达情况。结果:AR、ER、PR阳性数BPH组分别为22、10、6例;PCa组分别为18、14、2例,两组差异无显著性。随访30例PCa患者术后的生存期表明:AR表达阳性者平均生存时间为6.41年,AR阴性者为4.28年,两者差异有统计学意义(P<0.05)。结论:BPH和PCa患者在性激素受体表达上的差异无显著意义;PCa患者中AR表达阳性者平均生存时间长于AR阴性者,后者的预后较差,对AR阴性者行激素治疗效果不确定。     

Madigan前列腺切除术对前列腺增生症的治疗效果

①目的 提高前列腺增生症的手术治疗效果。②方法 采用Madigan手术治疗前列腺增生症42例。③结果 42例均手术成功，25例尿道完整，17例损伤尿道缝合修复；术后出血少，恢复快；术后随访4-85个月，病人无尿道狭窄，尿失禁等并发症。④结论 Madigan手术为较理想的前列腺增生症开放手术治疗方法。     

原发灶未明的颈结转移癌31例临床分析

本文对我院自1983年至1989年收治的原发灶未明的颈结转癌31例进行临床分析。男18例。女13例;平均年龄47.5岁,颈结位于颈单侧26例,双侧5例;位于颈上部18例次、颈中部6例次、颈下部8例次、锁骨上窝4例次(右3、左1)。在转移癌位于颈上、中部的18例中,8例作咽轴部放射治疗,其3和5年生存率明显优于不作咽轴照射者,包括放疗在内和综合治疗比不加放疗的结果好。有4例疗后追踪找到了原发灶,其中2例为腮腺癌,2例分别为肺鳞、腺癌。转移灶位于锁骨上窝的4例预后最差。     

Amyloidaceous ulcerated gingival hyperplasia: a newly described entity related to ligneous conjunctivitis

Gingival hyperplasia may be genetic, may be acquired as a consequence of exposure to drugs and other agents or may appear as part of a more widespread disorder. Five patients who acquired gingival hyperplasia due to amyloidaceous deposits staining only for fibrin are presented. This appears to be a new entity related to ligneous conjunctivitis.     

维拉帕米灌注治疗前列腺术后膀胱痉挛性疼痛的临床疗效观察

Surgical results of performing R4 gastrectomy for gastric cancer located in the upper third of the stomach

Because gastric cancers located in the upper third of the stomach are difficult to detect at an early stage, the surgical results remain poor. We performed R4 gastrectomy as a radical procedure for 25 patients, involving complete resection of the latero-aortic and interaorticovenous lymph modes above and below the left renal vein, in combination with the ordinary R2 or R3 gastrectomy (the R4 group). These patients were compared with 156 others who underwent R2 gastrectomy alone (the R2 group). There were no significant differences in operation time, blood loss, or the incidence of complications between the two groups; however, when the survival rates of the patients with tumors invading beyond the subserosa were compared, the 5-year survival rate was found to be significantly higher in the R4 group than in the R2 group. Furthermore, in patients with para-aortic nodal involvement, a significant survival advantage was observed in the R4 group, as compared with the R2 group. These results suggest that the R4 gastrectomy is a rational approach for patients with advanced gastric cancer located in the upper third of the stomach.
