Objective The objectives of this study were to analyze the results of lung cancer screening from 9265 urban residents in Urumqi from year 2014 to 2016,and to evaluate the significance of early diagnosis and treatment of cancer for the lung cancer prevention.Methods A total of 31,177 people with high risk of lung cancer were assessed by cancer risk questionnaire surveyed from 40 to 69 years old residents in Urumqi.High-risk groups were assigned to low-dose spiral CT scan in Affiliated Tumor Hospital of Xinjiang Medical University.Results 9,265 people were scanned with low dose spiral CT and overall completion rate was 29.7％.There had 11.9％ detection rate in 1,005 people who were scanned positive pulmonary nodules.The detection rate was 31.9％ for 2,955 people who were scanned solid nodules(＜5 mm) and 2.5％ for 236 people who had the non solid nodules(＜ 8 mm).After screening,14 patients were diagnosed by pathology and the detection rate was 0.2％.The emphysema,pulnonary cysts,pulmonary bullae and other related lung disease were detected in 4,095 people and the detection rate was 44.2％.Conclusion The lung health status of Urumqi residents was found by a wide range of lung cancer screening,and the awareness of lung cancer prevention and control was greatly improved.It provided the basis for the establishment of effective prevention and treatment system,which was helpful to improve the early diagnosis and treatment rate of lung cancer.

Objective To compare the contents and features of licensed pharmacist qualification examination papers between those in abroad and domestic in order to provide the informations for the reforming the examination in our country.Method The characteristics of licensed pharmacist qualification examination among USA、UK、Australia and China were analysed and compared with classified statistic by using excel software.Results The scene questions are the main type in the three examination papers(＞50％).There were fewer questions examining the memory ability of examinees in abroad examinations,than that of ours.There were one question just had objects of pharmaceutical care (0.18％) in our examination.In the inspection of pharmaceutical knowledge application ability for the practice test(＞60％),covering all aspects of pharmaceutical care; And Chinese licensed pharmacists exam basic no object and pharmaceutical care link information feedback(＞60％),and the others are theoretical knowledge(＞20％).And in the three abroad examinations other common questions were about clinical drug therapy (＞90％),while they were the knowledge of pharmaceutical analysis and pharmaceutics in domestic examination papers (41.97％).Conclusion Licensed pharmacist qualification examination in our country ignored the ability of employing pharmaceutical knowledge and developing pharmaceutical care.The reformation of the licensed pharmacist qualification examination in our country is extremely urgent.

Objective　To explore the possibility of telomerase as tumor marker of lung cancer and to evaluate its value on early diagnosis of lung cancer. Methods　Telomerase activity was measured in 40 resected specimens of lung cancer and 40 preoperative fibro-optic bronchoscope biopsied specimens of suspected lung cancer by PCR based silver staining telomeric repeat amplification protocal (TRAP) respectively. Results　The positive rate of telomerase was 100％ in SCLC, but 84.8％ in resected samples and 95.7％ in biopsied samples in NSCLC. The positive rate of telomerase was 87.5％(35／40) in resected lung cancer tissues, 7.5％(3／40) in paracancerous tissues and 0％(0／40) in normal lung tissues (P＜0.01). 82.5％ (34／40) biopsied specimens of suspected lung cancer were detected with telomerase activity. Its sensitivity, specificity， and accurate rate was 96.4％, 71.4％, and 91.4％ respectively for detection of lung cancer, Youden’s Index (J)＝0.678，and SE（J）＝0.174. Conclusion　Telomerase may be a sensitive tumor marker of lung cancer. Detecting telomerase activity in preoperative fibro-optic bronchoscope biopsied specimens may contribute to early diagnosis of lung cancer.
