目的:观察胶原酶治疗腰椎间盘突出的疗效。方法:对1218例不同程度的腰椎间盘突出患者进行椎旁穿刺,注入胶原酶1200u进行溶解治疗。结果:91%的患者取得较好疗效,9%的患者疗效欠佳。结论:胶原酶是治疗腰椎间盘突出的一种有效方法。
目的 提高对创伤性假性动脉瘤并动静脉瘘的影像诊断水平。 方法 报告1例腰椎间盘手术所致的创伤性假性动脉瘤并动静脉瘘,比较分析MRA和DSA对该病的诊断价值。 结果 MRA能够明确创伤性假性动脉瘤及动静脉瘘的诊断,与DSA有良好的相关性。 结论 MRA对创伤性假性动脉瘤并动静脉瘘的确诊有重要价值,在一定程度上能够代替常规血管造影。
目的分析比较肝血管瘤不同栓塞剂的栓塞治疗结果,寻找更为理想、合理的方法。方法对12例肝血管瘤16例次经皮穿刺超选择性肝动脉插管行栓塞治疗,其中单纯碘化油栓塞2例次,碘化油+明胶海绵颗粒栓塞6例次,碘化油+聚乙烯醇(PVA)微球栓塞5 例次,碘化油+平阳霉素栓塞3例次。随访10~32个月。结果全部病例均取得较肯定的疗效,无并发症发生。碘化油+平阳霉素和碘化油+PVA微球两种方法疗效稳定,复发率低,优于前两种方法。结论肝动脉栓塞治疗肝血管瘤疗效肯定,几种栓塞剂中,碘化油+平阳霉素及碘化油+PVA微球最佳。
目的:建立兔VX2软组织肿瘤模型,研究其高频超声表现。方法:2006年2~6月在12只大白兔后肢建立软组织肿瘤模型,行高频超声检查。结果:12只大白兔成功建立软组织肿瘤模型,超声表现为等回声为主,肿瘤边缘区域血供较中央区域丰富。结论:兔软组织肿瘤模型易于建立,超声有一定的特征性表现。
Objective To assess the safety and effect of different intravenous chemotherapic regimens in patients with gastric carcinomas who had received gastrectomy. Method A systematic review of all the relevant randomized controlled trials (RCTs) was performed. RCTs were identified from Medline and Embase (1980-2001.4), Chinese Bio-medicine Database (1990-2001.1). Literature references were checked at the same time. We included randomized andquasi-randomized trials in patients with confirmed gastric carcinomas who had received gastrectomy comparing the effect of intravenous chemotherapy after gastrectomy with that of gastrectomy alone.Results Twenty trials involving 4 171 patients were included. Meta-analysis was done with fixed effects model. Heterogeneity analyses was performed also. The effects of intravenous chemotherapy with 5FU + MCCNU, 5FU + MMC, 5FU + BCNU or FAM after gastrectomy were failed to show have better effects than that of surgery alone. There were eleven trials which detailed the side effects according to the toxicity grade by WHO standard. The side effects halting treatment were haematologic and biochemical toxicity, debilitating nausea and vomiting. There were twenty-two patients died of chemotherapic toxicity. Conclusions Based on the review, there is no enough evidence to show that intravenous chemotherapy after gastrectomy have positive treatment effect on gastric cancer.
