旨在为河南省食品安全风险监测提供参考，对河南省市售的205份食用植物油中3-氯-1，2-丙二醇酯(3-MCPD酯)和2-氯-1,3-丙二醇酯(2-MCPD酯)的污染状况进行调查分析。结果显示：205份食用植物油中，3-MCPD酯污染水平高于2-MCPD酯，其中3-MCPD酯检出率为79.0%，均值为1.83 mg/kg，中位值为1.30 mg/kg；大豆油的3-MCPD酯检出率最高，为93.3%，中位值为1.72 mg/kg，其次是花生油，检出率为89.2%，中位值为1.06 mg/kg，橄榄油的3-MCPD酯和2-MCPD酯污染水平最低；2021年食用植物油中3-MCPD酯、2-MCPD酯检出率均高于2020年；城市、农村人群经由食用植物油摄入3-MCPD酯健康风险较低。不同食用植物油氯丙醇酯的污染水平差别较大，虽然居民经食用植物油摄入3-MCPD酯健康风险较低，但需要继续加强监测。In order to provide reference for food safety risk monitoring in Henan province, the pollution status of 3-chloro-1,2-propanediol(3-MCPD) ester and 2-chloro-1,3-propanediol(2-MCPD) ester in 205 edible vegetable oils sold in Henan province was investigated and analyzed. The results showed that the pollution level of 3-MCPD ester was higher than that of 2-MCPD ester in 205 edible vegetable oils. The detection rate of 3-MCPD ester was 79.0%, with an average value of 1.83 mg/kg and a median value of 1.30 mg/kg. The detection rate of 3-MCPD ester in soybean oil was the highest (93.3%), and the median value of 3-MCPD ester was 1.72 mg/kg. The second was peanut oil, the detection rate was 89.2%, and the median value was 1.06 mg/kg. Olive oil had the lowest pollution levels of 3-MCPD ester and 2-MCPD ester. The detection rates of 3-MCPD ester and 2-MCPD ester in edible vegetable oil in 2021 were higher than those in 2020. The health risk of 3-MCPD ester intake through edible vegetable oil in urban and rural populations was low. The pollution levels of different edible vegetable oils vary greatly, and although the health risk of residents ingestion of 3-MCPD ester through edible vegetable oils is low, it needs to continue to strengthen monitoring.

[Objectives]This experiment was conducted to study the effects of intrauterine growth retardation(IUGR)on proliferation, apoptosis and antioxidant genes and protein expression of porcine placenta. [Methods]In this experiment, the placentas of normal birth weight and IUGR piglets were selected from newly delivered sows, and they were divided into the control group and IUGR group. Each group contained five replicates. Immunohistochemistry(IHC)was used to detect the PCNA expression in the placental cells. The apoptosis of placental cells was detected by TUNEL. RT-qPCR was applied to detect the mRNA expression of NRF2, HO-1, NQO1, SOD1, SOD2, GCLC and GCLM. Western blot(WB)was applied to determine the protein expression of NRF2 and HO-1. [Results]The results showed as follows:Stronger PCNA immunostaining was observed in the control group, while weaker PCNA staining was observed in the IUGR group. The percentage of apoptotic cells was 12.56% in the control group, whereas that of the IUGR group was 19.63%, the apoptosis rate of the IUGR group was significantly higher than that of the control group(P<0.05). The results of RT-PCR showed that compared with the control group, the mRNA expression of NRF2, NQO1, SOD1, SOD2, GCLC and GCLM in placenta of the IUGR group was significantly decreased(P<0.05). While the expression of HO-1 mRNA showed no significant difference between the control group and the IUGR group(P>0.05). The results of WB showed that the protein expression levels of NRF2 and HO-1 in the control group and the IUGR group were not significantly different(P>0.05). [Conclusions]Intrauterine growth retardation could inhibit the proliferation of porcine placental cells, increase apoptosis and decrease the expression of antioxidant genes and proteins in porcine placenta.

With dichloromethane as solvent, the poly（lactic acid）/poly（caprolactone）mixture tissue engineering scaffolds with mass ratio of 1:1 were prepared by supercritical CO2 induced phase separation-circulation drying process. The influences of operating parameters, such as polymer concentration, operating pressure, operating temperature, cycling drying time and CO2 flow rate, on the pore size and structure are also investigated. The results showed that with the increasing of polymer concentration and operation temperature, the diameters of pore scaffolds decreased.With the increasing of the operating pressure, the diameters of pore scaffolds increased and pore diameter distribution became non-uniform.With the increasing of CO2 flow rate, the diameters of pore scaffolds decreased.Circulation drying time made a little influence on the scaffolds pore diameters, but had an important influence on process feasibility.In the range of this work, the mixture scaffolds, prepared at the blend solution of 25 wt%, the operating pressure of 12 MPa, the operating temperature of 45°C, the CO2 flow rates of 31 kg/h, are favorable to tissue engineering.

A Honeycomb shaped porous medium model was constructed, the flow of the fluid inside it was numerically simulated by using software Fluent, the effects of different initial velocity and different pore size on the flow characteristics of porous media and their effects on the attachment and growth of microorganisms in porous media were investigated. The results show that with the increase of initial flow velocity in porous media, the fluid shear force increases, and the probability of microbial growth reduced. At the same condition of initial velocity, with the pore size increasing, the areas for microbial growth reduced, and it is difficult to form biofilm. With the thickness of porous carrier increasing, the velocity in the bottom of the porous carrier decreases, thus microorganisms on the bottom of porous carriers fall off because of no nutrients. The best parameters obtained in this simulation are the parameter of fluid flow characteristics is 0.001m/s and the aperture diameter of model structure is 20μm. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed to determine the survival trends in Taiwan clinics. We expect the results to provide important information for practitioners and the government for their operation and health policy making. Methods: We used 2000-2010 NHI claim data and statistics from the Statistical Bureau, National Statistics of Taiwan. Clinics located in outlying islands, as well as Chinese physicians and dentists, were excluded from this research. Survival curves and Cox regression were used to analyze the trends in clinic closures and explore the factors influencing the survival of clinics during the study period. Results: A total of 7,347 clinics were initiated between 2000 and 2010. Among the clinics, 5,361 remained open and 1,986 closed. The survival curve indicated that 7,347 clinics had significantly decreased after the 700th day of operations. The top 3 closure specialties were general medicine (37.5%), family medicine (33.9%), and rehabilitation medicine clinics (28.7%). The age of physicians, number of staff members, income, and clinic visits were significant determinants associated with closure. The top 3 counties of clinic closures were Yun-Lin, Tai-Tung, and Miao-Li counties. Conclusions: Between 2000 and 2010, of the 7,347 initiated clinics studied, closures occurred after the 700th day of operations. The highest three specialties of closure were general medicine, family medicine, and rehabilitation medicine. [ABSTRACT FROM AUTHOR]
