Objective To investigate the prevalence rates of diabetes, impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and related factors in the university staff. Methods 617 subjects were selected from 1 519 cases with the fasting blood glucose level ≥5.6 mmol / L in the annually physical examination among 3 851 population in a university community. All 617 subjects were taken the blood glucose and insulin test for the fasting and 2 hour after 75 g glucose intake. The fasting lipids, BUN and Cr were determined. The demographic data including height, weight, waist circumference and blood pressure was also collected. Results The numbers of normal glucose tolerance (NGT), IFG, IGT, IFG+IGT and newly diagnosed DM were confirmed in 374 (60.62%), 60 (9.72%), 59 (9.56%), 41 (6.65%) and 83 (13.45%); totally, 243 (39.38%) cases with abnormal glucose metabolism. The highest DM prevalence was found in the group with BMI ≥28 kg / m2. In the group with hypertriglyceridemia, prevalence of DM, IFG and IFG +IGT was 12.50%, 8.33% and 8.33%. In the group with hypercholesteremia and hypertriglyceridemia together, prevalence of DM, IFG+IGT, IFG and IGT was 18.87%, 7.17%, 11.32% and 12.83%. DM prevalence increased with the higher triglycerides level. No differences of HOMA-IR was found among groups of DM (0.80?0.82), IFG (0.64?0.72), IFG+IGT (0.61?0.77), IGT (0.35?0.68), but all these obviously higher than that of NGT group (0.17?0.80). No differences of HOMA-B among the IGT (3.97?0.69), NGT (3.95?0.78), IFG (3.84?0.72), IFG+IGT (3.80?0.78) groups, but all these higher than that of NGT(3.69?0.88)group. Conclusion About 40% of these subjects in the university population had their blood glucose ≥5.6 mmol/L. In these subjects with blood glucose ≥5.6 mmol/L, about 40% of them had abnormal blood glucose level, including 13.45% diabetic patients. The highest prevalence of IFG, IGT, IFG+IGT was found in the group aged 60~70, the highest prevalence of DM in the group aged 70~80 and increased paralleled with the BMI and aging, was associated with lipids disorder, particularly with hypertriglyceridemia. IR existed in the pre-diabetes state and was worst in the DM, with most severe ? cell function failure.

Objective To understand the basic information of the number, classification, and distribution of radiation work units in non-medical institutions in Shanxi Province, China, and to analyze the status quo of health management and radiation protection measures for radiation workers, so as to provide a scientific basis for occupational exposure protection in non-medical radiation work units and better protect the occupational health rights and interests of radiation workers. Methods A questionnaire survey was conducted to investigate some non-medical institutions in Shanxi Province. On-site testing was carried out to determine the risk factors for radioactive occupational diseases in the selected non-medical institutions. Results In 220 non-medical institutions, there were 340 radiation devices and 2284 radioactive sources. The rate of individual dose monitoring was 92.7% and the rate of occupational health examination was 87.2%. These devices were equipped with 325 detection instruments for radiation protection, 1316 personal protective equipment, and 730 personal dose alarms. Radiation occupational disease risk factors were investigated in 101 institutions. Conclusion The occupational health management of radiation workers in non-medical institutions in Shanxi Province is generally in line with the national standards. However, there is still a big gap with the level of occupational health management in medical institutions. The health administration departments should clarify the management measures for non-medical institutions and strengthen their supervision and management functions.

Carotenoids are secondary metabolite responsible for colored pigments in plants and microbes (Li et al., 2022). They are a class of C40 tetraterpenoids consisting of eight isoprenoid units, and can be classified into carotenes and xanthophylls on the basis of their functional groups (Saini et al., 2015). Carotenes can be linear (phytoene, phytofluene, and ζ-carotene) or branched (β-carotene and α-carotene). Xanthophylls comprise β,β-xanthophylls (β-cryptoxanthin, zeaxanthin, violaxanthins, and neoxanthin) and β,ε-xanthophylls (α-cryptoxanthin, α-carotene, and lutein). Citrus fruits are complex sources of carotenoids, which are the principal pigments responsible for the typical orange color of most types (Chen, 2020). The difference in total carotenoid content and the diversity of carotenoid isomer proportion also accounts for other colors of citrus fruits, such as yellow, red, and pink (Chen, 2020).

This paper aims to detect the antigens in porcine circovirus type 2 (PCV2) vaccines by high-performance size-exclusion chromatography (HPSEC) coupled with multi-angle laser light scattering (MALLS). With purified inactivated PCV2 and PCV2 virus-like particles (VLP) as references, two inactivated vaccines (a and b) and two VLP vaccines (c and d) for PCV2 from four manufacturers were analyzed by HPSEC-MALLS after demulsification. The antigen peaks in HPSEC-MALLS were identified by PCV2 antigen test strips, Western blotting and transmission electron microscope (TEM). The repeatability and linearity of the method were investigated. The results showed the virus antigens in the two inactivated vaccines were eluted at about 13.3 min in HPSEC. The molecular weight of these antigens was 2.61×106 (±4.34%) Da and 2.40×106 (±2.51%) Da, respectively, as calculated by MALLS. The antigen peaks of the two VLP vaccines also appeared at 13.3 min and the molecular weight was 2.09×106 (±2.94%) Da and 2.88×106 (±11.85%) Da, respectively, which was close to the theoretical molecular weight of PCV2. Moreover, an antigen peak of VLP vaccine c was observed at 11.4 min and the molecular weight was 4.37×106 (±0.42%) Da. The antigen was verified to be the dimer of VLP by TEM. Vaccine d and purified Cap VLP antigens were tested repeatedly, and the RSD of the peak area (n=3) was all < 1.5%, indicating that the method was repeatable. The purified VLP were diluted in serial and tested for linearity. The result suggested good linear relationship between the peak area of VLP or VLP aggregates and the protein concentration of the sample with R2 of 0.999 and 0.997, respectively. Thus, the method met the requirement for quantification and aggregate analysis. This method is accurate and efficient in in vitro quality evaluation and improvement of PCV2 vaccine.

OBJECTIVES:
The measurement of diabetic foot ulcers is important for the success in diabetic foot ulcer management. At present, it lacks the accurate and convenient measurement tools in clinical. In recent years, artificial intelligence technology has demonstrated the potential application value in the field of image segmentation and recognition. This study aims to construct an intelligent measurement model of diabetic foot ulcers based on the deep learning method, and to conduct preliminary verification.
METHODS:
The data of 1 042 diabetic foot ulcers clinical samples were collected. The ulcers and color areas were manually labeled, of which 782 were used as the training data set and 260 as the test data set. The Mask RCNN ulcer tissue color semantic segmentation and RetinaNet scale digital scale target detection were used to build a model. The training data set was input into the model and iterated. The test data set was used to verify the intelligent measurement model.
RESULTS:
This study established an intelligent measurement model of diabetic foot ulcers based on deep learning. The mean average precision@.5 intersection over union (mAP@.5IOU) of the color region segmentation in the training set and the test set were 87.9% and 63.9%, respectively; the mAP@.5IOU of the ruler scale digital detection in the training set and the test set were 96.5% and 83.4%, respectively. Compared with the manual measurement result of the test sample, the average error of the intelligent measurement result was about 3 mm.
CONCLUSIONS
The intelligent measurement model has good accuracy and robustness in measuring the diabetic foot ulcers. Future research can further optimize the model with larger-scale data samples.
