霍奇金淋巴瘤组织中H／RS细胞与其背景细胞的微切割及其IgH基因重排检测

目的 从基因水平探讨霍奇金淋巴瘤(HL)组织中H／RS细胞(Hodgkin and Reed-Sternberg cells)是否起源于B细胞、H／RS细胞的克隆性以及与背景淋巴细胞的相互关系。方法 对33例经典霍奇金淋巴瘤(cHL)石蜡刮片组织进行IgH基因重排分析，并对其中6例重排阳性的病例经B细胞特异性激活蛋白(BSAP)免疫标记，将标记阳性的H／RS细胞和背景淋巴细胞进行微切割后进一步行IgH基因重排分析。结果 16例石蜡刮片组织IgH基因重排阳性。对6例经BSAP标记的cHL成功进行了微切割，其中19管H／RS细胞中，有14管出现重排阳性，细胞数目不同的各管阳性率无显著性差异(P=0．290)；12管背景淋巴细胞有2管出现重排阳性，H／RS细胞与背景淋巴细胞的阳性率有显著性差异(P=0．002)。结论 支持H／RS细胞来源于B细胞的理论，认为部分背景淋巴细胞可能具有瘤性增生活性，参与H／RS细胞的前体细胞组成。     

对诊断PADAM的血清游离睾酮界限值的初探

目的探寻诊断中老年男子部分雄激素缺乏综合征(PADAM)血清游离睾酮(FT)的界限值。方法根据60例45岁以上健康男性完成伊斯坦布尔症状量表(ISS)与视听性刺激(AVSS)时阴茎勃起监测结果进行分组,计算AVSS勃起功能正常组推算的游离睾酮(CFT)值的参考范围。结果AVSS勃起功能正常组CFT的中位数为0．37(0．20～0．52)nmol/L,异常组的中位数为0．25(0．12～0．40)nmol/L,z=2．25,P＜0．05,差别有显著性意义。两组性功能症状的差别也有极显著性意义(P＜0．01)。CFT的界限值是0．20nmol/L。结论研究用ISS和AVSS勃起功能正常对象的血清FT值,可为诊断PADAM建立界限值。     

创伤性睾丸脱位5例报告

目的 探讨创伤性睾丸脱位的诊断和治疗。方法 对所收治的5例患的诊治情况进行分析研究，并结合复习有关献。结果 1例手法复位成功，4例行手术复位．1例发生睾丸萎缩后切除患睾。结论 创伤性睾丸脱位临床少见，漏误诊率较高。对骨盆部、会阴部、阴囊部外伤患应警惕本病；详细检查阴囊及睾丸．确诊后尽早行手法或手术复位固定．定期随访。     

原发性前列腺印戒细胞癌(1例报告并文献复习)

目的探讨原发性前列腺印戒细胞癌的临床特征。方法回顾性分析1例原发性前列腺印戒细胞癌患者的临床资料,并结合文献进行复习讨论。结果患者前列腺穿刺活检病理报告为前列腺印戒细胞癌,免疫组织化学检查示PSA( ),PAS、CEA、LCA、CKH(-),行双侧睾丸切除术和氟他胺治疗,术后1月死于肺部转移。结论原发性前列腺印戒细胞癌来自前列腺腺泡上皮,确诊依靠病理组织学和免疫组化检查。临床罕见,恶性程度高,预后较差。

Laryngeal tuberculosis: a review of 26 cases.

OBJECTIVES: To review the clinical characteristics of laryngeal tuberculosis. STUDY DESIGN: Retrospective case series. SUBJECTS AND METHODS: Medical records of 26 histopathology-confirmed cases in a tertiary medical center from 1992 to 2006. RESULTS: The female patients were significantly younger than male patients. Hoarseness is the most common symptom (84.6%) because true vocal fold is most commonly involved (80.8%). Infection usually involves unilateral (66.7%) and right-side larynx but multiple subsites of the larynx (57.7%). The appearance of the affected larynx may have mixed features and change before diagnosis. Laryngeal tuberculosis is usually misdiagnosed as laryngeal cancer, especially in patients with malignant signs such as enlarged cervical lymph nodes and vocal fold immobility. Chest film is better than sputum examinations for screening. CONCLUSION: We should be especially alert about TB infection when facing young female patients with unusual laryngeal lesions. Extensive laser excision before diagnosis should be avoided because after antituberculous treatment, prognosis is usually good and vocal fold immobility could be reversible.     

The characteristics of Hep-2 cell with multiple drug resistance induced by Taxol.

OBJECTIVE: To investigate the characteristics of Hep-2 cell with multidrug resistance (MDR) induced by Taxol. STUDY DESIGN: Hep-2 cells were exposed in stepwise escalating concentration of Taxol to develop the resistant cell line-Hep-2T. Cell cycle distribution, apoptosis, and rhodamine accumulation were studied through flow cytometry. The MDR1 and MRP1 genes were detected through real-time quantitative RT-PCR, and the corresponding proteins were detected through Western blotting. RESULTS: The drug resistance of Hep-2T cells to Taxol, doxorubicin, gemcitabine, 5-FU, and cisplatin all increased. The percentage of G0/G1 phase and the antiapoptosis ability increased significantly compared with Hep-2 cells. Both MDR1 and MRP1 also increased at gene and protein level, though MDR1 was more prominent. CONCLUSION: More emphasis should be laid on MDR1/Pgp, the non-Pgp substrate chemotherapeutic agents, and the changes of cell cycle distribution to prevent MDR induced by Taxol. SIGNIFICANCE: These findings may provide theoretical support for the reverse of MDR.
