Objective:To understand the monitoring levels of individual dose to radiation workers in Jiangsu province from 2011 to 2018, and to analyze their changing trends.Methods:Through National Individual Dose Registry, the data on the monitoring result of occupational external exposure of radiation workers in our province was collected, and statistical analysis was performed.Results:A total of 176 134 radiation workers in Jiangsu province were collected from 2011 to 2018. The annual collective effective dose was 58 man·Sv and the average annual effective dose was 0.35 mSv. The average annual effective doses to medical radiation workers for interventional radiology and nuclear medicine were both 0.41 mSv, with significantly higher NRE ratios than others ( χ2=219.1, P<0.05). By 2018, the numbers of monitored workers were 25 714 for medical radiation, accounting for 81%, with an average annual effective dose of 0.24 mSv, and 6 169 for industrial radiation, accounting for 19%, with an average annual effective dose of 0.18 mSv. Conclusions:The average annual effective dose to radiation workers in Jiangsu province is in consistency with the relevant national standards. The dose values for radiation workers in interventional and nuclear medicine are relatively high. The protection measures in their workplace should be improved. Meanwhile oversight of radiation protection should be enhanced for individual radiation workers in Jiangsu province.

OBJECTIVETo investigate the effect of light intensity on growth and photosynthetic of Chrysanthemum morifolium.
METHODThe growth characteristics of C. morifolium were measured under different treatments (100%, 80%, 60%, 40% and 20% of full sunlight). The photosynthetic characteristics and chlorophyll fluorescence parameters of leaves under different light intensity were determined by a LI-6400 photosynthesis system and a PAM-2100 chlorophyll fluorescence system.
RESULTWith the reduction of irradiance, the diameter of the stem reduced, plant height, leaf length, leaf width and length/width raised, assimilation product increased; Content of photosynthetic pigment increased between light intensity 100%-40% reduced under 20% treatment, chlorophyll a/b decreased. Light compensation point (LCP), apparent quantum yield (AQY) increased first and reduced later, photosynthesis rate (P(n)), stomatal conductance (G(s)), intercellular CO2 concentration (C(i)) and transpiration rate (T(r)) decreased, stomatal limitation value (L(s)) rose. Chlorophyll fluorescence parameters F(v)/F(m) increased, phiPS II, F(v)'/F(m)', ETR and qP increased between irradiance 100%-60%, NPQ decreased, such as phiPS II decreased and NPQ increased when irradiance was lower than 40%.
CONCLUSIONWeak light condition was unfavorable to the growth of C. morifolium and the light conditions of culture should be control between 80%-60% of full sunlight.

To observe the clinical effect of Yisui decoction plus western medicine in treating multiple system atrophy patients, totally 65 patients from China-Japan Friendship hospital during 2008-2012 with complete clinical data and received consecutive traditional Chinese medicine and western medicine treatment for more than 3 months were observed changes of traditional Chinese medicine symptom score, part 1 of unified multiple system atrophy rating scale, orthostatic hypotension before treatment and after 3 months treatment. After 3 months treatment, total effective rate of traditional Chinese medicine symptom was 70.8%. Compared with before treatment, score of part 1 of unified multiple system atrophy rating scale was obviously reduced after 3 month treatment (P < 0.001). Ex- cept swallow function without significant improvement, the remaining projects of unified multiple system atrophy rating scale were im- proved obviously (P < 0.05), of which the most obvious differences were orthostatic symptoms, falls and intestinal function (P < 0.001). Orthostatic hypotension after 1 month treatment and 3 month treatment was obviously better than before treatment (P < 0.001). There was no significant difference in orthostatic hypotension between 1 month treatment and 3 month treatment. The research results show that Yisui decoction plus western medicine has a certain effect on improving clinical symptoms of multiple system atrophy patients, especially has a significant effect on orthostatic hypotension, and can maintain a stable clinical effect in a certain period of time.
