| 1 | 198例胃癌手术标本Her-2蛋白表达与临床病理的相关性和靶向治疗显示文摘背景与目的:通过组织芯片(tissue microarry,T M A)和免疫组织化学(immunohistochemistry,IHC)技术检测人类表皮生长因子受体2(Human epidermal growth factor receptor 2,Her-2)在胃癌(gastric carcinoma,GC)中的表达,研究胃癌中Her-2表达的临床意义,为胃癌靶向治疗奠定理论基础。方法:构建包含198例胃癌组织和89例正常胃黏膜的组织芯片,应用免疫组化方法检测胃癌中Her-2蛋白的表达。分析Her-2表达与临床病理参数之间的相关性及其对预后的影响。结果:198例胃癌中男性147例,女性51例,男女比例为2.9∶1。患者年龄31~85岁,中位年龄66.5岁。按照Lauren's分型分为肠型169例,弥漫型29例。组织芯片免疫组化结果显示198例胃癌细胞中Her-2总表达率为32.8%,而正常胃黏膜无表达。Her-2表达与肿瘤大小、组织类型、肿瘤侵袭深度和TNM分期有关。肠型胃癌的表达率(36.7%)明显高于弥漫型胃癌(10.4%,P=0.005)。Her-2蛋白表达与患者性别、年龄、肿瘤部位及预后无关。结论:胃癌中Her-2蛋白的表达率为32%,其表达与胃癌的某些生物学行为有关。肠型胃癌Her-2蛋白表达率明显高于弥漫型胃癌。因此,肠型胃癌患者可能为曲妥珠单抗靶向治疗的主要群体,并有可能从辅助靶向治疗中获益。 | 奚文崎 张本炎 金晓龙 杨卫平 燕敏 王建承 | 2010 | 中国癌症杂志2010，20，12： | 11 |
| 2 | Therapeutic effects of combined oxaliplatin and S-1 in older patients with advanced gastric cardiac adenocarcinoma显示文摘AIM:To evaluate the effects and safety of combination chemotherapy with oxaliplatin (L-OHP) and S-1 (SOX regimen) in older patients with advanced gastric cardiac adenocarcinoma (GCA). METHODS: Seventy patients with advanced GCA were classified according to age into an older group (≥ 75 years) and a control group (< 75 years). The SOX regimen was administered to the two groups as follows: S-1 (40 mg/m2 po bid) on days 1 to 14 followed by a 7-d off period, plus L-OHP (65 mg/m2 iv) for 2 h on days 1 and 8 of a 21-d cycle. This regimen was repeat-ed for four to six cycles. Response and swallow statuses were evaluated after two cycles (6 wk). Effects and toxicity were evaluated four weeks after chemotherapy was completed. RESULTS: The response rate was 65.6% (21/32) in the older group and 68.4% (26/38) in the control group (χ2 = 0.062 and P = 0.804). Improvement in swallowing was 78.1% (25/32) in the older group and 76.3% (29/38) in the control group (χ2 = 0.032 and P = 0.857). Effi cacy was 68.8% (22/32) in the older group and 65.8% (25/38) in the control group (χ2 = 0.069 and P = 0.793). Toxicities were reversible and similar in both groups (P > 0.05). CONCLUSION: The SOX regimen is an effective, safe and well-tolerated regimen for older patients with advanced GCA. | She-Gan Gao Rui-Nuo Jia Xiao-Shan Feng Xuan-Hu Xie Tan-You Shan Li-Xian Pan Na-Sha Song Yu-Feng Wang Kai-Li Ding Li-Dong Wang | 2011 | World Journal of Gastroenterology2011，17，47： | 10 |
| 3 | 卡培他滨有关物质色谱-质谱联用鉴定显示文摘目的:采用LC-MS法对卡培他滨有关物质进行结构鉴定。方法:采用C18色谱柱(250 mm×4.6 mm,5μm),以0.1%冰醋酸溶液-甲醇-乙腈为流动相进行线性梯度洗脱,对卡培他滨及其有关物质进行分离;通过电喷雾正离子化高分辨TOF/MS鉴定有关物质的离子组成、并结合MS/MS和对照品对照鉴定各有关物质的结构。结果:建立的色谱条件下各有关物质与主成分分离良好,检测到12个有关物质,其中2个为起始原料、3个为合成副产物和7个为降解产物。结论:建立的LC-MS法能有效地鉴定卡培他滨有关物质,为其质量控制和工艺优化提供参考。 | 张戈 刘超逸 陈雷霖 杭太俊 宋敏 | 2015 | 中国新药杂志2015，24，16： | 1 |
