The total alpha and beta radioactivity in water can basically reflect the overall level of radioactivity in water, and can also be used as an important index for monitoring radioactive pollution of water quality. Therefore, the measurement of total alpha and beta radioactivity in water is the main method to screen and evaluate the radioactivity of drinking water^[1,2]It is also the main parameter of China's drinking water sanitary standard radioactivity index and drinking water radioactivity risk monitoring^[3,4]It is one of the methods used by the International Atomic Energy Agency (IAEA) to validate the ability of monitoring radioactivity in water^[5]。 In order to ensure the accuracy of the measurement data of total alpha and beta radioactivity in water, reduce the systematic error introduced by the method, and compare the analysis and detection capabilities of different laboratories, in 2012, with the approval of China Center for Disease Control and Prevention of the Ministry of Health, our institute was responsible for organizing 44 laboratories across the country to compare and analyze the measurement of total alpha and beta radioactivity in water, and in 2013, the unqualified laboratories were reviewed. Reported here below.

Digital subtraction angiography (hereinafter referred to as DSA) is mainly suitable for the examination and treatment of systemic vascular diseases and tumors. Because of the large amount and long time of X-ray exposure during interventional diagnosis and treatment, the radiation dose of workers exceeds that of ordinary X-ray examination by tens or even hundreds of times^[1]It will cause occupational injuries to staff and even occupational radiation diseases. However, the radiation protection evaluation of occupational hazard control effect for DSA construction projects is rarely reported in China. In order to control or eliminate occupational hazards from the source and protect the health of staff and the surrounding public, the radiation protection evaluation of occupational hazards control effect of DSA interventional radiation diagnosis and treatment construction project in a hospital was carried out.

Nuclear energy is a high-efficiency and low-carbon energy source. Vigorous development of nuclear power in China is not only the requirement of rapid economic development, but also the need of low-carbon emission reduction. According to statistics, at present, there are 22 units in operation or trial operation and 27 units under construction in China; It is planned that by 2020, 100 units will be in operation, 16 provinces and municipalities will have nuclear power plants, and there will be hundreds of millions of residents within 30 km of nuclear power plants. Therefore, it is particularly important to pay attention to nuclear power safety. In particular, the occurrence of the accident at Fukushima Daiichi Nuclear Power Plant in Japan on March 11, 2011 and the assessment of health consequences suggest the importance of paying attention to the health survey of residents around the nuclear power plant. China's health and family planning departments attach great importance to the health status of residents around nuclear power plants, and have successively issued the Guidelines for Health and Hygiene Monitoring of Residents around Nuclear Power Plants, the National Nuclear Emergency Plan and the Standards for Health Survey of Residents around Nuclear Power Plants (WS/T 440-2014)^[1]Guide relevant provincial and municipal health institutions to carry out health and hygiene monitoring of residents around nuclear power plants.

Kimura's disease (KD) is a rare chronic inflammatory disease, clinically manifested as painless lymph node enlargement or soft tissue mass, with slow progression. It is often neglected because there are no self-conscious symptoms. Its etiology and pathogenesis are not yet clear. The main manifestations are painless soft tissue masses in the head and neck, which can be multiple and easy to relapse. The pathological manifestations are mainly lymphocyte proliferation and eosinophil infiltration, often accompanied by regional lymph node or parotid gland invasion. Five cases of Kimura's disease are reported in this study as follows.
