国产罗红霉素杂质谱及与合成工艺相关性评价

目的:考察国产罗红霉素的杂质谱情况,并与合成工艺相关性进行初步评价。方法:采用欧洲药典7.0版罗红霉素有关物质方法对国产样品进行分析,使用Waters Symmetry ShieldTMC18色谱柱(150 mm×3.9 mm,5μm),以0.52 mol·L-1磷酸二氢铵溶液[用氢氧化钠溶液(8.5→100)调节p H至4.3]-乙腈(74∶26)为流动相A,以水-乙腈(30∶70)为流动相B,梯度洗脱(0~50 min,100%A;50~51 min,100%A→90%A;51~80 min,90%A;80~81 min,90%A→100%A;81~100 min,100%A),色谱柱温15℃,自动进样器温度8℃,检测波长205 nm。以系统适用性对照品对11种已知杂质进行定位,以罗红霉素为外标计算杂质含量。结果:国产罗红霉素中检出的主要杂质为杂质H、杂质F和杂质C。杂质H是影响国产罗红霉素质量的主要杂质。结论:国产罗红霉素的主要杂质H和杂质F与合成工艺中起始反应物硫氰酸红霉素中红霉素B和去甲基红霉素的含量相关;杂质C为反应中间体红霉素(E)肟的残留,通过优化纯化工艺可降低杂质C的含量。国产罗红霉素的合成工艺可有效的去除侧链合成中引入的杂质G、杂质J和杂质K。

金属内支架置入联合三维适形放射治疗肝癌合并门静脉癌栓

Objective To study the clinical efficiency of metallic stent implantation in combination with three-dimensional conformal radiation therapy in the treatment of hepatocellular carcinoma (HCC) pa-tients with portal vein tumor thrombus. Methods 22 cases of HCC patients with portal vein tumor thrombus were devided into 2 groups: 10 patients (group A) recieved stent implantation in combination with conformal radiation therapy, 12 patients (group B) recieved stent implantation and transcatheter arterial chemoembolization. The adverse reactions, and liver function before and after treatment were compared between the two groups. The stent patency rate at 4, 6 and 12 months and the survival rate at 3, 6 and 12 months were followed up. Comparison of liver function was analyzed by Wilcoxon signed rank test. Compari-son of stent patency rate curves and survival curves was analyzed by Log rank test. Results The portal vein catheterization was successful in all the patients. The stents were successfully implanted by transhepatic portal vein approach, and portal vein stenosis was re-opened. There was no abdominal hemorrhage in all the patients, but there were symptoms of abdominalgia, fever, nausea, vomiting and flatulence of varying de-grees after interventional operation, and these symptoms were relieved by symptomatic treatment in one week. All patients in group A completed the treatment. Ⅰ-Ⅱ degree gastrointestinal tract reactions occurred in 3 cases, Ⅰ-Ⅱ degree myelosuppression occurred in 2 cases, and they were all completely relieved after treatment. The stent patency rate at 4, 6 and 12 months was 90%, 70%, 30% in group A; and 50%, 25%, 16.7% in group B (P < 0.05). The survival rate at 3, 6 and 1 2 months was 100%, 80%, 30% in group A and 91.7%, 41.7%, 16.7% in group B (P < 0.05). Conclusion Stent implantation combined with three-dimensional conformal radiation therapy is a good treatment for hepatocellular carcinoma with portal vein tumor thrombus and causes less damage to liver.

金属内支架置入联合三维适形放射治疗肝癌合并门静脉癌栓

目的 研究金属内支架置入联合三维适形放射治疗对原发性肝癌合并门静脉癌栓的治疗效果. 方法回顾性分析22例肝癌伴门静脉癌栓患者,其中门静脉支架置入联合适型放射治疗组(A组)10例,门静脉支架置入和经动脉化疗柃塞组(B组)12例.比较两组患者治疗后的不良反应发生情况及治疗前后肝功能变化情况,随访4、6、12个月的支架通畅率和3、6、12个月的生存率.肝功能比较采用Wilcoxon符号秩检验,支架通畅率曲线和生存率曲线的比较采用Log rank检验. 结果两组患者均成功建成门静脉通路,并通过经皮肝穿刺门静脉分支路径成功置放支架,门静脉狭窄均得到开通.患者均未发生腹腔出血,但术后均有不同程度的腹痛、发热、恶心、呕吐、肠胀气等症状,通过对症处理均在l周内缓解.A组患者均完成治疗,Ⅰ～Ⅱ度胃肠反应3例,Ⅰ～Ⅱ度骨髓抑制2例,对症处理后完全缓解.A组患者的4、6、12个月支架通畅率分别为90%,70%、30%,B组分别为50%,25%.16.7%,两组的通畅率曲线差异有统计学意义(χ<'2>=4.33,P<0.05).A组患者的3、6、12个月生存率分别为100%、80%、30%,B组分别为91.7%、41.7%,16.7%,对两组的生存率曲线差异有统计学意义(χ<'2>=4.05,P<0.05). 结论采用支架置入并联合三维适形放射治疗对肝癌伴门静脉癌栓有较好的疗效,且对肝脏的损害相对较小.
