ObjectiveThis study aimed to evaluate the health risks of cadmium exposure in the local rice of Wenzhou residents by analyzing the pollution level and spatial distribution of cadmium in locally produced Wenzhou rice.MethodsThe monitoring data of local rice in Wenzhou from 2016 to 2021 were collected， and the spatial distribution of the cadmium concentration of local rice was displayed visually by ARCGIS 10.2. The Ordinary Kriging interpolation analysis was used to analyze spatial interpolation. The cadmium exposure was estimated by combining the concentration of cadmium in local rice with food consumption data. The health risk was assessed using a simple distribution model.ResultsThe median of cadmium in 740 local rice samples was 0.069 mg/kg. The detection rate and over-limit rate were 95.68% and 11.49%， respectively. The areas with high cadmium concentrations in local rice were mainly distributed in the northwest of Lucheng City and the central area of Rui’an City. The average exposure and the exposure of high-consumption groups （P95） to cadmium through eating local rice in Wenzhou adult residents were 12.04 and 21.08 μg/kg·BW， respectively. The average and high-consumption group exposure to cadmium in children were 17.02 and 32.04 μg/kg·BW， respectively. The average exposure and the exposure of high-consumption groups to cadmium by eating local rice in Lucheng were greater than the provisional tolerable monthly intake （PTMI）.ConclusionThe cadmium exposure levels of 1.16% of all adult residents in Wenzhou by eating local rice were higher than the PTMI. Children with high rice consumption had a higher cadmium exposure level from local rice， and residents had a higher health risk of cadmium exposure by eating local rice in Lucheng.

ObjectiveTo provide basis for further ensuring the safety of student meals， the microbial contamination status in kindergarten， primary and secondary school canteens in Wenzhou in the past five years were investigated.MethodsFood samples collected in Wenzhou from 2016 to 2020 were detected for hygienic target bacteria （Aerobic Plate count and Escherichia coli） and foodborne pathogens （Staphylococcus aureus， Bacillus cereus， Salmonella and Listeria monocytogenes）， and data were analyzed with SPSS 18.0.ResultsThe microbial contamination of student meal in 2016 was serious， with a unqualified rate as high as 23.58%. While the unqualified rates of student meal decreased by 6.27%， 6.80%， 9.06%， and 3.82% from 2017 to 2020 （χ2 = 60.852， P

Due to its great clinical significance, brain injury following cardiac arrest (CA) has attracted more attention now. Meanwhile, there are currently no approved real time objective methods used to monitor brain injury following CA. In this study, we adopt the method of nonextensive Kullback-Leibler Entropy in investigating the HRV signals from brain injury and compare the result with that of corresponding EEG analysis. The comparative analysis shows that Kullback-Leibler Entropy can reveal the injury level of brain following CA. And we propose a novel quantitative approach for monitoring brain injury.
