Objective To observe and compare the recent objective response rate and adverse reaction of docetaxe and irinotecan combined with cisplatin in the treatment of advanced non-small cell lung cancer (NSCLC). Methods Sixty-five patients with advanced NSCLC were randomly divided into goup A consisted of 33 patients received docetaxe plus capecitabine and group B consisted of 32 patients received irinotecan plus capecitabine with a 21-day regimen. Two or more cycles of chemotherapy were completed in each group. Results Sixty-five patients were assessable for efficacy and toxicities. In group A, 2 patients achieved complete response, 13 patients partial response, overall response rate was 45.45 % and the median progression-free survival (PFS) was 10.1 months. In group B, 2 patients achieved complete response, 12 patients partial response, overall response rate was 43.75 %, and the median PFS was 10.2 months. The efficacy and PFS were not significantly different between the two groups(P ＞0.05). The most common adverse reactions were myelosuppression and gastrointestinal response in the two groups. The main adverse reactions is anemia in group A and diarrhoea in group B. Patients in group A experienced more anemia. On the contrary,the rate in group B was more increased. No chemotherapy-related death was observed. Conclusion The effects of docetaxe combined with cisplatin and irinotecan combined with cisplatin in the treatment of advanced NSCLC are comparable and equivalent, and the adverse reactions can be tolerated.

Objective:To improve the CT bulb tube cooling rate and the testing method of the CT bulb tube temperature, and provide more stable platform for better bulb tube protection and longer life-span. Methods: The designed specified cold air machine could transfer the dry cold wind into machine rack, which can lower the ambient temperature of the machine rack and increase the air flow inside the machine rack and promote the efficiency of the heat exchange of the bulb tube oil cooling circuit. Results:the design of this system’s joint is light and handy, which could collect the instantaneous temperature change of the bulb tube, and carry out simple man-machine interaction monitoring. Conclusion:According to the bulb tube oil-way temperature and ambient temperature and relative humidity, the computer can dynamically adjust the refrigerating capacity and operation/cease of the air cooler. Then it can constitute the closed control loop, and accelerate the efficiency of the bulb tube’s heat dissipation, and promote the heat capacity of the bulb tube equivalently.
