Test results have revealed that compared with the commercial catalyst RAG under comparable reaction conditions the reaction conversion rate and product distribution provided by the novel catalyst were similar, but the olefin content in gasoline obtained thereof was decreased with the octane rating unchanged along with a slight reduction of olefin content in the LPG fraction. The hydrothermal stability of the novel catalyst was better than the commercial catalyst RAG.展开更多

The results of commercial application of these catalysts have revealed that they can satisfactorily meet the requirements for environmental protection, good economic benefits and capability for processing inferior FCC feed under new circumstances.展开更多

In this study, the correlation of gene expression profiles and clinical characteristics in non-small-cell lung cancer （NSCLC） was investigated. Methods Seventy-six Chinese patients with NSCLC were enrolled in the study to investigate mRNA expression profiles of excision repair cross complement group 1 （ERCC1）, thymidylate synthetase （TYMS）, ribonucleotide reductase （RRM1）, class Ill 13-tubulin （TUBB3）, and epidermal growth factor receptor （EGFR） genes and their correlation with patient clinical characteristics. A novel liquidchip technology was used to detect mRNA expression levels in formalin fixed paraffin embedded tumor pathology samples. The relationships between gene expression and clinical characteristics were assessed using the Mann-Whitney test. Results ERCC1 mRNA levels were higher in tumors from patients with metastatic disease than patients with non- metastatic disease （P=-0.021）, and higher in adenocarcinomas than squamous cell carcinomas （P=0.006）. Increased TUBB3 mRNA expression levels were found in patients with performance status （PS） 1 in comparison with PS 0 （P=0.049）, with poorly differentiated tumors in comparison with tumors that were moderately and well differentiated （P 〈0.000 1）, and with advanced stage in comparison with early stage disease （P 〈0.000 1）. Conclusions ERCC1 mRNA levels were higher in metastatic adenocarcinoma NSCLC; TUBB3 mRNA levels were significantly higher in poorly differentiated tumors and in advanced stage NSCLC, which indicates the poor prognosis.展开更多
