Objective: To monitor the content of bisphenol S ( BPS ) in vegetables and fruits in Henan Province and evaluate the dietary exposure risk of the population, so as to provide the basis for formulating relevant food safety standards. Methods: From 2018 to 2019, 276 samples of vegetables and fruits produced and sold in Henan Province were collected. BPS was determined by isotope dilution ultra performance liquid chromatography triple quadrupole tandem mass spectrometry ( UPLC-MS/MS ) , and the dietary exposure was calculated according to the dietary structure and average body weight of local residents. The risk index of BPS was calculated according to the daily tolerable intake ( TDI ) of bisphenol A ( BPA ). Results: The BPS contents in vegetables and fruits were 0.006-12.600 µg/kg and 0.006-9.380 µg/kg, the medians were 0.053 µg/kg and 0.023 µg/kg, the detection rates were 78.43% and 62.60%, respectively.The detection rate and content of BPS in vegetables were higher than those in fruits ( P<0.05 ). The maximum exposure of BPS from vegetables and fruits was 5.37×10-2 µg/ ( kgbw·d ), and the exposure risk index was 1.07 × 10-3, which was acceptable. Conclusions BPS was detected from vegetables and fruits in Henan Province. The detection rate and content of BPS in vegetables were higher than those in fruits. The health risk of BPS exposed by vegetables and fruits is small.

Objective:In this paper, based on the 4D dose distribution of the treatment plan, the effects of respiratory movement on the dose distribution of three-dimensional conformal radiation therapy (3DCRT) and sliding window intensity-modulated radiation therapy (SW-IMRT) techniques were analyzed, and the dose errors caused by respiratory movement based on the 4D dose distribution were evaluated.Methods:In this study, the dynamic thoracic phantom (CIRS-008A) was used to simulate the patient with a 3 cm spherical insert as the tumor. Four motion patterns were simulated with cos 4( x) and sin ( x) wave forms of 10 mm and 5 mm amplitudes. The 4DCT scans with the phantom were performed in different breathing modes, and the maximum intensity projection (MIP), average intensity projection (AIP) and 10 separate 4DCT phase images were transferred to the Eclipse treatment planning system. The targets were contoured on MIP, with corresponding 3DCRT and SW-IMRT plans designed and dose calculated on AIP. By copying the plan designed on the AIP to each phase image of the 4DCT set, the MATLAB software package was employed to register and superimpose all the phase-specific doses onto one of the reference phase to create a 4D-accumulated dose distribution. Both films (EBT2) and optically stimulated luminescence (OSLD) detectors were inserted in and around the target area of the phantom to measure the delivered doses. The calculated 4D-accumulated doses were compared to the measured doses and their differences were evaluated using Gamma analysis. Results:Under different respiration modes, the average Gamma index (3%/3 mm) passing rates between the 4D-accumulated doses and EBT2-measured doses for 3DCRT and SW-IMRT plans were (98.8±0.78)% and (96.4±1.89)%, respectively. The absolute measurements of OSLDs both inside and outside of the target area well matched the 4D-accumulated doses.Conclusions:4DCT can be effectively applied to evaluate the treatment plan dose distribution through 4D dose accumulation, which can potentially avoid cold spots and target under-coverage. Under different respiration modes, both 3DCRT and SW-IMRT plans provide dose measurements consistent with those predicted by the 4D-accumulated dose of treatment plan.

OBJECTIVEDuring progression of atherosclerosis, the vessel may develop either positive or negative remodeling. The pathophysiology of vascular remodeling is not fully understood. This study investigated the relationship between plaque characteristics and arterial remodeling using intravascular ultrasound imaging (IVUS).

METHODSA total of 77 patients (male 53, mean age 58 +/- 10 years) who underwent IVUS imaging (ClearView or Galaxy2, Boston Scientific, USA) of culprit vessel were enrolled in this study. Among the 77 patients, 31 presented with stable angina pectoris and 46 presented with acute coronary syndrome. Qualitative assessment of the lesion and quantitative measurement were performed in both stenotic and reference segments. The lesions were classified into soft plaque and hard plaque (including fibrous plaque, calcified plaque and mixed plaque) according to different ultrasound patterns of tissue reflection. The remodeling index (RI) was defined as the ratio of vessel cross sectional area (EEMcsa) of lesion segment to the mean reference EEMcsa. Positive remodeling was defined as RI > 1.0 and negative remodeling as RI < 1.0.

RESULTSOf 77 lesions, 45 (58%) had undergone positive remodeling, and 32 (42%) had negative remodeling. In comparison to the patients with negative remodeling, patients with positive remodeling presented with more acute coronary syndrome (74% vs. 43%, P = 0.006). Both the plaque area and the vessel area were significantly larger in the lesion with positive remodeling than in lesion with negative remodeling. The lesions with positive remodeling were predominantly soft (71% vs. 34%, P = 0.001) and had less calcification [21% vs. 54%, P = 0.003 and (18 +/- 37) degrees vs. (40 +/- 50) degrees, P = 0.027] compared with lesions with negative remodeling. The difference of clinical presentation and plaque characteristics between the patients with different patterns of remodeling is still significant with binary logistic analysis.

CONCLUSIONSCoronary arterial remodeling pattern is related to the clinical manifestation and the composition of plaque. Lesions presented with positive remodeling have a higher prevalence of soft plaque and less calcification.

Objective Through a two-year follow up program,this study was to analyze the urinary iodine frequency of a cohort in the intervention trial,concerning different doses of salt iodization,so as to explore the selection of appropriate concentration of salt iodization.Methods A multistage cluster sampling method was used to select three townships in two countries for community intervention with different doses [ ( 15 ± 5 ) mg/kg,(25 ± 5 ) mg/kg,( 35 ± 5 ) mg/kg ] of salt iodization.Results After intervention,the median of urinary iodine was reduced among the population.The urinary iodine frequencies of (15 ± 5) mg/kg and (25 ± 5) mg/kg among groups of children were mainly concentrated in 100-200 μg/L and 200-300 μg/L paragraphs in A county.While the 300 μg/Lparagraph had an overall decline in B county,the 100 μtg/L and 200 μg/L paragraph ratio increased but the trend seemed to be slow.The 100-300 μg/L paragraph of the four treatment groups took a larger proportion and kept smooth in a more ideal state.However,the control group still maintained at above 250 μg/L level.Conclusion The iodine supplementation should be gradually implemented in Chongqing.The doses of salt iodization should be reduced from the current (35 ± 15)mg/kg to (25 ± 5) mg/kg in the economically developed areas.At the same time,we need to continuously follow the changes of the condition.

OBJECTIVETo observe effect of formula of removing both phlegm and blood stasis (TYTZ) in improving hemorheology and blood fat of mini-swine with coronary heart disease of phlegm-stasis cementation syndrome.

METHODThirty-six Chinese mini-swine were randomly divided to six groups: the normal control group, the model group, the Shujiangzhi group and TYTZ groups with doses of 2.0, 1.0 and 0.5 g x kg(-1), with six mice in each group. Except for the normal control group, all of other groups were fed with high-fat diet for 2 weeks. Interventional balloons are adopted to injure their left anterior descending artery endothelium. After the operation, they were fed with high-fat diet for 8 weeks to prepare the coronary heart disease model of phlegm-stasis cementation syndrome. In the 8th week after the operation and administration, the changes in hemorheological parameters, serum lipid level, myocardial ischemia level and range were observed.

RESULTCompared with the normal control group, the model group showed significant increase in serum TC, TG, LDL-C and VLDL-C levels (P < 0.01), whole blood viscosity under the shear rate of 5 s (-1) and 60 s (-1) (P < 0.01), and myocardial ischemia degree and range (P < 0.01). Compared with the model group, TYTZ groups revealed significant decrease in myocardial ischemia degree and range (P < 0.01), serum TC, TG, LDL-C and VLDL-C levels (P < 0.05 or P < 0.01) and whole blood viscosity under the shear rate of 5 s(-1) and 60 s(-1) (P < 0.05).

CONCLUSIONTYTZ could improve the abnormal hemorheology in Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome, and regulate serum lipid, with a certain efficacy for coronary heart disease of phlegm-stasis cementation syndrome.
