Objective： to determine the role of excision repair cross-complementing group 1 gene （ERCC1） and ribonucleotide reductase subunit M1 （RRM1） expression in predicting response and survival in Chinese patients with advanced stage non-small cell lung cancer （NSCLC） treated with platinum-based chemotherapy. Methods： Formalin-fixed, paraffin-embedded biopsy tissues were retrospectively obtained from 160 advanced NSCLC patients. mRNA expression levels of ERCC1 and RRM1 were determined by real-time PCR. Results： Associations between mRNA expression level of ERCC1 and RRM1 and clinic-pathologic parameters were analyzed. One handred and forty two （88.75%） specimens were successfully amplified. mRNA expression level of ERCC1 and RRM1 was negatively associated with tumor response. ERCC1 expression levels ranged from 0.01 to 78.79 [median 0.63, mean 4.25 and standard deviation （SD） 9.23] and RRM1 from 0.00 to 30.91 （median 0.63, mean 0.87 and SD 3.36）. By adopting cut-off values according to median expression levels, we found that MST in patients with low ERCC1 mRNA levels was significantly longer in overall population than in patients with higher levels （18.63 versus 13.69 months, log-rank 5.73, P=0.017）, but we did not found the survival benefit of the patients with low expression level of RRM1. （19.07 versus 14.88, log-rank 1.66, P=0.197）. Further, in the multivariable Cox regression model analysis we found that low level of ERCC1 expression, the presence of weight loss and target therapy, were significant prognostic factors for survival. Conclusion： ERCC1 expression is associated with patients’ survival in Chinese advanced NSCLC patients treated with platinum-based regimen and may serve as a biomarker in predicting tumor response and clinical outcome in the patient population.

Objective： To evaluate the efficacy and safety of celecoxib treatment of advanced non-small cell lung cancer （NSCLC）, and combined therapy by molecular analysis. plus platinum-doublet as first-line chemotherapy in to determine the subgroup benefiting from celecoxib Methods： A total of 44 treatment-naive patients of advanced NSCLC with positive cyclooxygenase-2 （COX-2） expression confirmed by immunohistochemical （IHC） staining were designed to receive celecoxib plus platinum-doublet chemotherapy （cisplatin plus gemcitabine, novelbine or docetaxol） from February 2005 to May 2007. On 5-7 day before chemotherapy, 400 mg celecoxib was administered twice a day orally until obvious evidence of disease progression or intolerable toxicity was found. Adverse events were recorded according to NCI-CTC criteria. The primary endpoint was overall survival （OS）. The secondary endpoints included progression-free survival （PFS）, 1-year survival rate, response rate （RR） and safety. Additionally, we detected epithelial growth factor receptor （EGFR） status including EGFR gene amplification by real-time PCR and gene mutations by DHPLC followed by sequencing. Results： The response rate was 45% （20/44）, and the disease control rate （DCR） was 59% （26/44）. The median progression-free survival time and median survival time were 6 m and 18 m, respectively. The l-year survival rate was 68%. Chemotherapy cycle numbers and best response were found to be the predictive factors for PFS by COX model analysis （P=0.023 and P=0.000, respectively）. No factor was found to affect OS. The most common toxicities included neutropenia and nausea/vomit. EGFR gene amplification was an independent prognostic factor influencing OS （P=0.0002）. Patients with EGFR mutations （exon 21） had a tendency of disease progression （P=0.041）. Conclusion： Encouraging activities of celecoxib combined with platinum-doublet chemotherapy were demonstrated in treatment-naive patients with advanced NSCLC, with good tolerances. For

Background The genotype of epidermal growth factor receptor （EGFR） is associated with tyrosine kinase inhibitor and effectiveness of therapy, but its role in cytotoxic chemotherapy is still unknown. Previous studies indicated that certain EGFR mutations were associated with response and progression free survival following platinum based chemotherapy. Our recent studies have identified that EGFR genotypes in the tumour tissues were not associated with response to the first-line chemotherapy in Chinese patients with advanced non-small cell lung cancer （NSCLC）. In this study, we investigated associations of EGFR genotypes from plasma of patients with advanced NSCLC and response to first-line chemotherapy and prognosis. Methods We enrolled 145 advanced NSCLC patients who had received first-line chemotherapy in our department. We examined plasma EGFR genotypes for these patients and associations of EGFR mutations with response to chemotherapy and clinical outcomes. Results There were 54 patients with known EGFR mutations and 91 cases of wild types. No significant difference was detected in the response rate to first-line chemotherapy between mutation carriers and wild-type patients （37.0% vs. 31.9%）. The median survival time and 1-, 2-year survival rates were higher in mutation carriers than wild-types （24 months vs. 18 months, 85.7% vs. 65.7% and 43.7% vs. 25.9%, P=0.047）. Clinical stage （Ⅳvs. Ⅲb）, response to the first-line chemotherapy （partial vs. no） and EGFR genotype were independent prognostic factors. Conclusion Plasma EGFR mutations in the Chinese patients with advanced NSCLC is not a predictor for the response to first-line chemotherapy, but an independent prognostic factor indicating longer survival.

中子辐射俘获反应在反应堆运行、核装置设计及核天体物理研究中起重要的作用.4πBaF_(2)探测装置有着高时间分辨能力、低中子灵敏度、高探测效率等优点,适合开展中子辐射俘获反应截面数据的测量.中国原子能科学研究院核数据重点实验室建立了伽马全吸收装置(Gamma total absorption facility,GTAF),该装置用28块六棱BaF_(2)晶体和12块五棱BaF_(2)晶体构成了外径25 cm,内径10 cm的球壳,覆盖了95.2%的立体角.利用GTAF在中国散裂中子源Back-n束线上,测量了197Au(n,γ)的反应截面数据.测量数据通过能量筛选、PSD方法、晶体多重性筛选进行了初步本底扣除,随后结合对^(nat)C及空样品的测量数据对本底进行了分析及扣除,获得了197Au俘获反应的产额,利用SAMMY程序拟合得到了^(197)Au在1—100 e V的共振能量、中子共振宽度和伽马共振宽度参数.实验测量结果与ENDF/B-VIII.0数据库符合良好,其共振参数存在一定差异,分析原因可能与GTAF能量分辨率、Back-n的中子能谱测量精度、以及实验本底扣除方法相关,这也是下一步工作的重点.
