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.     

左半结肠癌并发急性肠梗阻一期切除吻合的合理性与评价

目的 探讨左半结肠癌并发急性肠梗阻一期切除吻合的合理性与评价。方法 回顾性分析我院1994年2月期间至2003年2月采用一期切除吻合术治疗左半结肠癌并发急性肠梗阻64例的l临床资料。结果 全组患者无死亡及腹腔感染。7例（10．9％）发生切口感染，3例（4．7％）发生吻合口漏，均治愈。住院时间10～36d，平均16d。结论 部分经选择的病例中开展一期切除吻合术是安全、可行的，选择性应用一期切除吻合术是治疗左半结肠癌并发急性肠梗阻的理想术式。

一种FⅨ基因多态性在广西人群中的检出

目的研究广西人群ＦⅨ（凝血因子Ⅸ）基因多态性。方法利用聚合酶链反应（ＰＣＲ）和限制性内切酶Ｔｒｕ９Ｉ（同功酶即ＭｓｅＩ）酶解技术，对１２０名志愿者进行研究。结果首次在广西人群中发现ＦⅨ基因５′侧翼６９８位核苷酸存在Ｔｒｕ９Ｉ多态性，该多态性由８３ｂｐ／５８ｂｐ＋２５ｂｐ组成，二者的基因频率在受检的１８０个ＦⅨ基因中，分别为０．６２２和０．３７８，女性杂合子频率为０．４７３。结论该发现有助于血友病乙携带者的检测及产前基因诊断。     

良、恶性脑膜瘤性激素受体和外源凝集素受体的检测

采用 ABC 免疫组化技术对82例脑膜瘤活检组织(良性脑膜瘤67例、恶性脑膜瘤15例)进行了三种性激素受体和12种 LR 的测定.结果证实脑膜瘤是性激素的靶组织,ER阳性率74.4%,PR 阳性率75.6%。AR 阳性率29.3%.ER 阳性率与性别有关,女性高于男性;PR 阳性率与组织类型有关,脑膜内皮型阳性率最高,过渡型居中,而纤维母细胞型及砂粒体型阳性率较低;AR 阳性率与组织分化程度有关,恶性脑膜瘤中 AR 阳性率高于良性脑膜瘤中 AR 阳性率.这些结果为进一步探讨性激素受体在脑膜瘤的生物学行为上所起的作用及对脑膜瘤实施内分泌治疗提供理论依据.12种 LR 中只有 PSA 受体在良性脑膜瘤中的阳性率高于恶性脑膜瘤,故这一结果可作为良、恶性脑膜瘤诊断的依据.三种性激素受体与 LR 染色结果经配对卡方检验证明无相关性,因此 LR 的测定不能代替性激素受体的测定.
