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.

OBJECTIVETo investigate the occurrence of supernumerary upper incisor teeth in Pax6-/- mouse fetuses and to provide a model to explore the role of Pax6 in the upper incisor development and the mechanism of supernumerary teeth involving Pax6.

METHODSTwenty Pax6-/- mouse fetuses of strain DEBA were isolated on E18.5 (embryonic day). The fetuses were sectioned serially in coronal plane and stained with haematoxylin and erosion, then the presence of supernumerary teeth in the upper anterior area was examined histologically, and also the number, morphology and structure of lower incisor germs and the first and second molar germs in the maxilla and mandible were observed histologically. Eighteen E18.5 mouse fetuses of strain DEBA with Pax6+/+ genotype were used as control.

RESULTSOf the 20 Pax6-/- fetuses examined, four possessed a single supernumerary tooth in the upper incisors' region. No supernumerary upper incisor teeth were observed in any of the 18 Pax6+/+ fetuses examined. In the regions of lower incisors and the first and second molars of the maxilla and mandible, no significant difference was observed between Pax6-/- and Pax6+/+ fetuses regarding the number, morphology and structure of tooth germs.

CONCLUSIONSThe results suggest that Pax6 played an important role in the development of upper incisor teeth in mice.

OBJECTIVETo assess the prevalence of pre-hypertension and hypertension as well as the association with overweight/obesity in Shanghai adolescents.

METHODSSchool children aged 11 - 17 years in four schools in Shanghai were included in this survey. All students were visited in May 2010 at school by trained nurses or physicians who administered a questionnaire and carried out anthropometric measurements. Anthropometric measurements included height, weight, heart rate and blood pressure. Repeat measurements were performed in school children with elevated blood pressure within one month. The pre-hypertension and hypertension was defined on the basis of the 2004 National High Blood Pressure Education Program Working Group definitions. The overweight and obesity was defined using cutoff points recommended by Working Group of Obesity, China (WGOC).

RESULTSThere were 4175 school children aged 11 - 17 years [mean (15.0 ± 1.9) years, 52.3% (n = 2183) girls and 47.7% (n = 1992) boys]. There were 72.5% (n = 3025) participants with normal blood pressure [ girls (n = 1666) 76.3% and boys (n = 1361) 68.3%], 18.0% (n = 750)participants with pre-hypertension [14.2% (n = 310) for girls and 22.1% (n = 440) for boys], 8.3% (n = 346) participants with stage 1 hypertension [8.2% (n = 179) for girls and 8.3% (n = 165) for boys] and 1.3% (n = 54) participants with stage 2 hypertension [1.3% (n = 28) for girls and 1.3% (n = 26) for boys]. The prevalence of overweight and obesity was 6.7% (n = 147) and 3.0% (n = 66) for girls and 13.7% (n = 273) and 6.3% (n = 125) for boys. After adjusting for gender, age, parental history of hypertension and physical activities, multivariable logistic regression analysis showed that the overweight [adjusted odds ratio and 95% confidence interval: 1.42 (1.16 - 1.75)] and obesity [adjusted odds ratio and 95% confidence interval: 2.35 (1.78 - 3.11)] were independent predictors of elevated blood pressure in this cohort.

CONCLUSIONSThe prevalence of elevated blood pressure is common in adolescents in Shanghai. Overweight and obesity are closely associated with the elevated blood pressure in this cohort.
