Nuclear fuel cycle standardization is important for the safe and innovative development of the nuclear fuel cycle industry, especially when China has currently entered a high-quality development stage. Therefore, conducting strategic research on nuclear fuel cycle standardization becomes significant for boosting China’s nuclear industry. In this article, we analyze the development status of nuclear fuel cycle standardization in China and abroad, investigate the key problems of nuclear fuel cycle standardization in China from the perspectives of working mechanism, development balance, leading role, and support ability, and propose the major tasks and relevant countermeasures. Specifically, the major tasks involve seven aspects: post-stage standards of the nuclear fuel cycle, standards for key technologies, advanced standards, frontier basic standards, safety and environmental protection standards, international standardization, and basic capacities for standardization. Furthermore, the countermeasures comprise including nuclear fuel cycle standardization into the 14th Five-Year Plan of the nuclear industry, improving the standardization mechanism, increasing investment, and strengthening the construction of standardization talent teams.

Objective To discuss the clinical features of the patients suffering from cervical cancer who visited Daping Hospital affiliated to Third Military Medical University in recent 10 years. Methods The clinical data of the patients who were pathologically diagnosed as invasive cervical cancer in Daping Hospital of TMMU from Jan. 2004 to Dec. 2013 were retrospectively analyzed. They were divided into different age groups and analyzed according to age, clinical features, pathological type, and surgical approach. Results Clinical data of 950 patients with invasive cervical cancer were reviewed in this study. The mean age of the patients was 46.9 years. The clinical features, pathological type, and surgical approaches were different in different age groups. Analysis of the age structure of the patients, the onset age of cervical cancer seemed to increase year by year. Conclusion The clinical features of cervical cancer are diversity in different age, and the strategy for controlling its development should be varied according to age.
