恶性胃肠道间质瘤34例临床分析

目的探讨恶性胃肠道间质瘤临床、病理特点。方法回顾性分析2002—2004年收治的34例恶性胃肠道间质瘤的临床和病理资料。结果病人临床表现中腹痛与消化道出血较常见，发生部位最常见为小肠和胃；肿块平均直径10．2cm；术后均经病理学诊断为恶性。术后12例复发，4例死亡。结论肿瘤大小、位置、核分裂像、免疫组化指标是判断胃肠道间质瘤良、恶性的重要指标，对病人诊断为恶性或潜在恶性的胃肠道间质瘤必须进行包括手术治疗在内的综合治疗。     

后纵韧带钩辅助下颈椎后纵韧带骨化物切除减压术

目的探讨后纵韧带钩辅助下颈椎后纵韧带骨化物前路切除的适应证、方法及其临床效果。方法患者19例，男14例，女5例；年龄51-71岁，平均59岁。术前影像学检查结果示后纵韧带骨化物局限型6例，分节型13例；椎管狭窄率32％-75％，平均54％。术前神经功能JOA评分4-14分，平均9．6分。行颈前路常规手术入路，椎体开槽切骨达椎体后壁，范围超过后纵韧带骨化灶。利用后纵韧带钩插入后纵韧带下，钩起后纵韧带及骨化物，在后纵韧带与硬膜间形成一间隙，直视下用超薄型枪状咬骨钳切除后纵韧带及骨化物，而后植骨固定，恢复颈椎稳定性。结果随访6-36个月，平均16个月。术后JOA评分8～16分，平均12．8分，恢复率42％＇-92％，其中疗效优9例，良7例，可3例，优良率84．2％。4例患者术后并发脑脊液漏，保守治疗后均获得痊愈。术后CT和MR检查显示骨化后纵韧带切除完全，脊髓和硬膜囊形态恢复良好。结论后纵韧带钩可提高颈椎前路手术切除后纵韧带骨化物的安全性和有效性，适用于局限型和分节型、切除范围在两个椎节之间的颈椎后纵韧带骨化症患者。     

Anatomic and spiral computed tomographic study of the genial tubercles for genioglossus advancement.

OBJECTIVE: To measure and compare Chinese mandibular genial tubercles measured anatomically and with computed tomography (CT). STUDY DESIGN AND SETTING: Spiral CT scans were taken of 40 adult human skulls; the superior genial spines were measured using anatomic and CT methods. RESULTS: The height and width of the superior genial spines, mandible thickness, and distance from the menton to the inferior and superior margins of the superior genial spines were 5.82 +/- 0.71, 6.98 +/- 1.35, 11.95 +/- 1.59, 11.08 +/- 2.05, and 16.91 +/- 2.30 mm from anatomic measurements and 6.17 +/- 0.71, 7.01 +/- 1.13, 12.19 +/- 1.64, 10.41 +/- 1.55, and 15.73 +/- 2.12 mm using spiral CT, respectively. The anatomic and CT measurements were correlated. CONCLUSION: Spiral CT of the genial tubercles can help locate the osteotomy in genioglossus advancement. SIGNIFICANCE: This study acquired reference data on Chinese genial tubercles demonstrating that CT measurements of the genial tubercles reflect their anatomy, which should allow accurately locate the osteotomy.     

辅助发音器治疗腭咽闭合不全前后舌位置及运动特点比较研究

目的:讨论S-A治疗前后舌位置及运动形态对腭裂患者的影响。方法:采用标准头颅侧位X线片对腭裂术后VPI患者,S-A治疗前后、语音治疗一年后舌静止及运动形态进行了研究。结果:静止位S-A治疗后舌背明显降低,语音治疗后舌位逐渐抬高,发/a:/音时S-A治疗后及语音治疗一年后,不良代偿习惯逐渐消除,语音清晰度明显升高。结论:VPI的矫正及语音治疗对根除舌不良代偿习惯,获得清晰准确的发音具有重要意义。     

醋酸棉酚对大鼠肾皮质形态结构的影响

醋酸棉酚每天30mg/kg(6次/周)给药6～8周后,大鼠肾曲小管线粒体肿胀,嵴模糊,伴有早期溶酶体增多、增大,形态多样,其后转而减少、变小。肾近曲小管微绒毛水肿,部分肾曲小管基底膜水肿。未见肾小球毛细血管内皮细胞、基膜和足细胞的超微结构明显变化。     

某些降压药对血脂的影响

报道52例高血压病人服降压药双氢克尿噻、心得安、复方降压片和硝苯啶1～2月后血脂的变化,结果显示,双克(25～50mg/日)对血脂的主要影响是升高TG,加用心得安(30mg/日)后,TG升高幅度更大;TC有上升趋势,HDL-C变化较小。复降片(3片/日)对血脂的影响较大。不仅TG明显升高、TC也有明显升高,而HDL-C则有显著下降、HDL-C/TC比值下降也十分显著。硝苯啶(30mg/日)对血脂也产生不利影响,血TG浓度上升,TC浓度增加,而HDL-C变化不大。这种变化已被看作为对长期接受这些药物治疗的病人外加了一个致动脉粥样硬化的危险因素。

Postoperative deep vein thrombosis in the Taiwanese Chinese population

Reports of the incidence of postoperative deep vein thrombosis in the Chinese population of Taiwan are few in the literature. Over a 3 year period, the fibrinogen degradation products test, the pulse volume recorder, and venography were used to study 220 patients undergoing major operations at the Veterans General Hospital in Taipei, Taiwan. Deep vein thrombosis was found in 17 patients (7.7 percent). A comparison of the three diagnostic methods showed that the sensitivities of the fibrinogen degradation products test and the pulse volume recorder were 56.3 percent and 93.7 percent, respectively; the specificities, 97.4 percent and 95.7 percent, respectively; and the accuracies, 85.5 percent and 95.5 percent, respectively. These results support the combined use of the fibrinogen degradation products test and the pulse volume recorder for screening and diagnosing deep vein thrombosis.
