[Objective]To explore the diagnostic value of dual-energy computed tomography(DECT)for left atrial appendage thrombosis/spontaneous echocardiographic contrast(LAAT/SEC).[Methods]A retrospective analysis was done on 64 non-valvular atrial fibrillation patients who planned to undergo radiofrequency ablation between November 2020 and November 2021.All patients underwent DECT and transesophageal echocardiography(TEE),and then were divided into LAAT/SEC group and non-LAAT/SEC group based on the TEE results.The clinical data and imaging parameters of the two groups were compared and analyzed.Univariate and multivariate logistic regression analyses were performed to determine the independent risk factors for LAAT/SEC,and a prediction model was constructed.[Results]A total of 64 patients with atrial fibrillation were enrolled in this study,including 42 non-LAAT/SEC patients and 22 LAAT/SEC patients.There was no statistically significant difference in gender and body mass index(BMI)between the two groups(P>0.05).CHA2DS2-VASc score and left atrial diameter were higher in the LAAT/SEC group than in the non-LAAT/SEC group(P=0.047;P<0.001).Significant differences(P<0.001)were observed in the ratio of Hounsfield unit of LAA and ascending aorta(LAA/AA HU ratio)at the first phase of DECT and quantitative parameters such as Zeff,Rho,λHu,and nIC.Multivariate logistic regression showed that Zeff and Rho were the independent factors for the diagnosis of LAAT/SEC.A Zeff-Rho based model predicting LAAT/SEC was subsequently developed,with Area Under the Curve(AUC)of 0.96(95%CI:0.92,1.00)and the accuracy of 0.92(95%CI:0.83,0.97).[Conclusions]The two quantitative parameters Zeff and Rho are independent risk factors for the diagnosis of LAAT/SEC.The DECT derived Zeff and Rho may have better diagnostic performance than single parameter and conventional CT in detecting LAAT/SEC.

Anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) myopathy is one of the subtypes of immune-mediated necrotizing myopathy. Anti-HMGCR antibodies induce complement activation,subsequently resulting in myofiber necrosis,regeneration with autophagy abnormalities and mitochondrial changes. The age of onset is from children to adulthood. Some patients have a history of exposure to statins. Most patients are subacute onset. The patients with chronic progressive process, are more like muscular dystrophy. The main symptoms are proximal symmetrical weakness of limbs and usually accompanied with extra-muscle symptoms. The MRI showed muscle edema in all patients and fatty infiltrates in some patients. Myositis-specific auto-antibodies and muscle biopsies play key roles in diagnosis of HMGCR myopathy. Corticosteroids and immunosuppressants were first line therapy. Pediatric patients or patients with chronic course are usually refractory, and the efficacy of different combinations of immunosuppressants needs to be further investigated.

Objective To investigate the effects of human leukocyte-associated antigen-G (HLA-G) expression in silencing trophoblast cell line JEG-3 under normal and hypoxic conditions on invasion and proliferation of JEG-3 cells. Methods Inhibition of HLA-G expression in JEG-3 cells by transfection of small interfering RNA (siRNA),the transfected JEG-3 cells were divided into 4 groups: normoxia control group, hypoxia control group, normoxia inhibition group and hypoxia inhibition group. The levels of HLA-G mRNA and protein in 4 groups of cells were detected by real-time quantitive PCR and western blot. The proliferation activity and invasion ability of 4 groups of cells were determined by methylthiazolyl tetrazolium (MTT) assay and invasion assay.Results (1) Real-time quantitive PCR technology showed: the level of HLA-G mRNA in the hypoxic inhibition group (0.220±0.050) was significantly different (P<0.05), when compared with that in the hypoxic control group (0.630±0.030) and normoxic inhibition group (0.400± 0.020). (2) Western blot analysis showed: the expression level of HLA-G protein in the hypoxic inhibition group was 0.260±0.010, statistically different from that in the hypoxic control group (0.850±0.100) and the normoxic inhibition group (0.560±0.020; P<0.05).(3) MTT showed: proliferative activity of JEG-3 cells in the normoxic inhibition group was 0.490 ± 0.070, the ability of cell proliferation was reduced. When compared with that in the normoxic control group (0.850±0.050), the differences was statistically significant (P<0.05). The proliferative activity of JEG-3 cells in the hypoxic inhibition group (0.330±0.070) was lower than that in the normoxic inhibition group (0.490±0.070), and there was a significant difference (P<0.05). (4) Invasion assay showed: compared with the normoxic control group (98±7), the invasive ability of JEG-3 cells in the normoxic inhibition group (73 ± 7) was weakened, and the difference was statistically significant (P<0.05). The number of transmembrane cells (52±11) of JEG-3 cells in the hypoxic inhibition group was lower than that in the hypoxic control group (72±7), and the difference was statistically significant (P<0.05). Compared with the normoxic inhibition group, the invasion ability of JEG-3 cells in the hypoxic inhibition group decreased, and the difference was statistically significant (P<0.05). Conclusion Under hypoxia, using siRNA technology to down-regulate the expression of HLA-G may affect the proliferation and invasion ability of trophoblast cells, which may be involved in the occurrence of hypertensive disorder of pregnancy.

Objective:To investigate the effect of Norcantharidin(NCTD)on the apoptosis of human ovarian cancer SKOV3 cells and its mechanism.Methods:Human ovarian cancer SKOV3 cells were cultured in vitro and treated with 52 μmol/L NCTD.The SKOV3 cells were divided into the control group and NCTD group(52 μmol/L).The morphological changes of SKOV3 cells were observed under an inverted microscope,and the changes of nucleus were observed under a fluorescence microscope.The changes of mitochondrial membrane potential were detected by flow cytometry after drug treatment for 24 h.Western blot was used to detect the expression levels of apoptosis-related proteins Bax,Bcl-2 and Wnt/β-catenin signaling pathway-related protein β-catenin in SKOV3 cells after drug treatment for 24 h.Result:Compared with that in the control group,NCTD inhibited the proliferation of SKOV3 cells,reduced mitochondrial membrane potential,induced apoptosis of SKOV3 cells,increased the expression of Bax protein,decreased the expression of Bcl-2 protein and β-catenin.Conclusion:NCTD-induced apoptosis of ovarian cancer SKOV3 cells may be related to the regulation of Wnt/β-catenin signaling pathway.

OBJECTIVETo understand the dietary consumption of residents in Xiamen and the content of phthalic acid esters (PAEs) in food, and to assess the plasticizer exposure risk of diet in Xiamen.

METHODSThe survey was conducted by stratified cluster random sampling method in Xiamen from September to October in 2010. According to the Xiamen administrative division, six neighborhood communities were selected as sampling units, then 25 families were randomly chosen from each sampling units.From the above 150 families, the permanent residents over the age of six were permitted to our study. The survey included 495 residents totally. These participants' information, such as basic personal information, physical activity levels, meal frequency and the average consumption of 33 kinds of food in 13 categories were collected using questionnaires. Thirteen categories included cereal and tubers, beans, vegetables, fungi and algae, fruits, dairy products, meat, seafood, eggs, snacks, beverages, cooking oil and spices. The height and weight of residents were measured and the average daily dietary intake was calculated. Thirty-three kinds of food in 13 categories were collected in supermarkets in Xiamen. According to the annual sales ranking, the top three-five brands of each kinds of food were selected and numbered, then two or three brands were chosen by random number table method from them; three completely individual packed samples in the same batch of each brand were detected; 243 samples were included in our study.100-500 g solid samples or 100-500 ml liquid samples were collected. The content of diethyl phthalate (DEP), dibutyl phthalate (DBP), di (2-ethylhexyl) phthalate (DEHP) in food were detected by liquid chromatography mass spectrometry, which expressed by median (minimum-maximum). The exposure dose, contribution rate and risk index of PAEs were calculated by point estimation method.

RESULTSAccording to the average daily dietary intake of residents in Xiamen, the top three ones in 13 categories of food were cereal and tubers (337.16 g/d, 18.21%), vegetables (309.12 g/d, 16.69%) and fruits (213.20 g/d, 11.51%). The content of DEP, DBP or DEHP among different categories of food was significantly different (χ² values were 58.05, 50.19 and 102.10, P < 0.01). Among 13 categories of food, seafood contained the most DEP (0.090 (0.000-0.324)mg/kg); cooking oil had the most DBP (0.700(0.000-2.980) mg/kg) and DEHP (5.115(0.000-24.160) mg/kg). DEP, DBP and DEHP exposure(0.19, 4.20, 18.10 µg × kg⁻¹ ×d ⁻¹)in dietary food in Xiamen were less than the reference dose(RfD) (800, 100, 20 µg × kg⁻¹ × d⁻¹) proposed by the United States Environmental Protection Agency (EPA), and the risk indexes were 0.02%, 4.20% and 90.50%, respectively. Among 13 categories of foods, seafood was the main source of DEP dietary exposure. The exposure dose and contribution rate of DEP in seafood were 0.18 µg × kg⁻¹ × d⁻¹ and 94.74%, respectively.Vegetables were the main source of DBP and DEHP dietary exposure. The exposure dose and contribution rate of DBP and DEHP were 1.48 µg × kg⁻¹ × d⁻¹, 35.24% and 6.07 µg × kg⁻¹ × d⁻¹, 33.54%, respectively.

CONCLUSIONThe food consumed by residents in Xiamen was overall in a safe state, but to some extent, there still exists DEHP exposure risk in foods.

Objective To improve fresh nurses′ implementation rate of standard clinical administration checking by applying situational simulation method, and enhancetheir ability of identifying hidden perils in nursing. Methods Totally 75 fresh nurses who graduated in 2016 were enrolled and divided into two groups (36 in control group and 39 in experimental group) according to randomized digital table method. Situational simulation method was applied in the experimental group, while the control group applied traditional nursing safety check training method. Then both groups′ satisfaction rate of lessons and self-confidence after training were recorded. Besides, their clinical administration checking behaviors after 3 months, the errors, hidden perilsand examining situations related to administration checking after 6 months,were also evaluated. Results Significant statistical differences were shown in satisfaction score (23.62 ± 2.02 in experimental group vs. 21.39 ± 1.98 in control group, t=4.818, P<0.01) and self-confidential evaluating score (35.67±2.02 in experimental group vs. 21.39±1.98 in control group, t=2.768, P<0.01). Observation of clinical administration checking behaviors 3 months after training had indicated significant differences in the number of nurses who check drug concentration (33 vs. 8, χ2=29.406, P<0.05) and executing time (30vs. 12, χ2=14.436, P<0.05).Statistical differences (χ2= 5.080-29.545, P< 0.01 or < 0.05) were also observed in the number of nurses checking bed number, patient name, drug name, dose, drug concentration and methods in and after operation. The potential nursing perils identified, and the number of nurses who identify hidden nursing perils 3 months and 6 months after training were significantly larger (χ2=50.591, 23.658, 3.914, P<0.05) in experimental group (33, 2, 10) than in control group (18, 1, 3),and there were no significant differences in the rate of potential perils and nursing error between both groups. Conclusion Situational method of administration, which is applied for fresh nurses in their initial working phase, transforms the basic and core checking system into clinical real-situation cases. It also shows an advantage of boosting their self-confidence of learning, improving the implementation rate of standard clinical administration checking and the ability of avoiding potential nursing perils.
