经尿道气化电切治疗前列腺增生

目的 探讨经尿道气化电切术(TUVP)治疗前列腺增生(BPH)的安全性和有效性.方法 对161例前列腺增生患者行TUVP治疗,其中伴全身症状和泌尿系并发症2种以上的高危患者、前列腺重量＞50g的患者共68例.平均年龄72.5岁,经围手术期处理后行TUVP治疗.结果 所有患者均安全度过围手术期.随访3～24个月,平均IPSS从26.6下降至6.6、MFR从6.2ml/s上升到18.6ml/s、PVR从376ml下降到8.9ml.结论 TUVP治疗BPH以及高危重度BPH是安全有效的,强调术中对前列腺尖部采用电切治疗以避免术后尿失禁等并发症的发生.     

原发性乳腺恶性淋巴瘤的诊断及外科治疗探讨

目的探讨原发性乳腺恶性淋巴瘤的诊断与治疗. 方法回顾性分析我院1992～2004年5例原发性乳腺恶性淋巴瘤的临床资料.5例均为术后组织学病理诊断.4例行乳腺癌改良根治术,1例行乳房单纯切除术.5例均行化疗及放疗. 结果乳腺癌改良根治术手术时间60～120 min,平均80 min;乳房单纯切除术加乳腔镜腋窝淋巴结清扫术手术时间75 min.术中出血量150～250 ml,平均200 ml.术后病理组织诊断均为弥漫性非霍奇金氏淋巴瘤,为B细胞来源.且均有腋窝淋巴结转移.全组病例随访6个月～12年,平均4.5年.2例II期,均死于肿瘤多器官转移;3例I期,肿瘤无复发. 结论原发性乳腺恶性淋巴瘤无明显特异性表现,术前诊断困难.钼靶X线照相,对诊断有帮助. 治疗可选择手术、放疗、化疗或单纯给予化疗和放疗.     

电化学刀治疗前列腺增生疗效观察

目的观察应用阳光XY-电化学刀治疗前列腺(BPH)临床效果并总结经验。方法选择有手术适应证的BPH患者,手术前采用经会阴B超测前列腺尿道长度。结果治疗后6月复查,82例患者1次拔管成功79例,2~3次拔管后自行排尿正常2例,总有效率98.8%,无效1例,无效率1.2%。结论腔内介入电化学刀治疗BPH是一种高效、安全、并发症少、痛苦小、费用低的方法,尤其是合并症较多已失去手术机会的患者可作为首选方法,但应进一步观察并积累成功经验和失败教训。     

Preference for donor site scar orientation in pedicled latissimus dorsi breast reconstruction

A survey was carried out to ascertain the preference for donor site scar orientation in patients undergoing pedicled latissimus dorsi breast reconstruction and their views on breast reconstruction in general. One hundred twelve women (59 Chinese, 53 Western) completed the questionnaire. Participants were asked to state their preferred scar orientation (i.e., oblique, horizontal, or vertical) based on photographs showing the position of the scars. Demographic information and views on issues surrounding breast reconstruction in general were also collected. Data was analyzed non-parametrically with chi-square test and t test. The mean age of participants was 39.5 years (20–73 years). Seventy-seven percent of the participants would opt for an immediate breast reconstruction if offered (p < 0.001). Eighty-six percent would have objection to the use of silicone implant as a whole or part of a reconstruction (p < 0.001). Vertical and horizontal scars were the preferred orientation, with no women choosing the oblique orientation as their first choice (p < 0.001). The non-Chinese of 40 years or older, as well as Chinese women from all age groups, preferred the horizontal scar (p < 0.05). We demonstrated that both culture and age impact on the preferred scar orientation in breast reconstruction. Women in the age group we commonly reconstruct favored the horizontal scar. However, the younger women of non-Chinese origin tended to favor the vertical scar.     

乳腺癌患者癌胚抗原检测的临床意义

目的探讨癌胚抗原(CEA)检测在乳腺癌诊断和判断预后中的作用。方法应用免疫组化方法检测64例乳腺癌、37例正常及良性病变中癌胚抗原的表达。结果乳腺癌中癌胚抗原的阳性率(68.8%)明显高于正常对照组(16.2%),有显著性差异(P<0.05)。乳腺癌有淋巴结转移的癌胚抗原的阳性率(81.3%),略高于乳腺癌没有淋巴结转移的癌胚抗原的阳性率(56.3%),无显著性差异。结论癌胚抗原的检测有助于乳腺癌的诊断,癌胚抗原可能是判断乳腺癌预后的重要指标。     

Mammaplasty: Shape,volume, and scar size

Recently many mammaplasty techniques have been presented with special attention paid to the resulting scar's size and its position. The surgeon should try to hid the scar, and if the inverted T incision is used, its horizontal branch should be as short as possible and kept in the breast area. Neverthelss, excessive concern about the final scar size should not interfere with the final results of the mammaplasty as far as shape, volume and lasting results are concerned. The author presents his experience in mammaplasty with respect to the volume, the shape, and the scar size interrelationships.     

人食管不典型增生上皮与原位癌的计算机纹理分析研究

采用计算机图象纹理分析和相关点阵检测技术,对人食管正常粘膜、不典型增生上皮及原位癌的不同纹理特征进行了观察。观察样品为常规病理切片,用计算机图象分析系统检测了组织的纹理特征。对受检图象建立了三种灰色分层关系矩阵,同时计算了8种纹理测度。结果显示,在重度不典型增生上皮和原位癌之间,其纹理测度和相关点阵检测数据均有显著性差异(P<0.05)。全部测量数据经计算机多元逐步判别分析,其正判率达90%以上。本研究结果表明,计算机纹理分析方法可正确地判别食管癌前病变和原位癌的组织结构异型性。提示本技术在食管癌的早期诊断方面具有肯定的实用性价值。     

正常及良性前列腺增生组织中表皮生长因子活性的测定

为了解表皮生长因子在前列腺组织中的作用，利用免疫组织化学方法和竟争放射受体法对人正常和良性前列腺增生组织中表皮生长因子的组织定位和活性进行了检测。结果表明表皮生长因子主要定位于前列腺的分泌上皮细胞，正常前列腺和良性前列腺增生组织中表皮生长因子的活性无显著性差异。提示前列腺组织中表皮生长因子的主要作用可能并非在于调节前列腺上皮细胞的增殖。
