Objective: Through inter-laboratory comparison to analysis and evaluation of the detection capacity of arsenic in the urine. Methods: Urine arsenic samples were prepared with normal human urine as matrix. The homogeneity of the samples was investigated and the results were statistically analyzed by single factor analysis of variance. 2 samples were issued to each participant laboratory. A robust statistical four-point distance method was used to calculate the results submitted by each participant laboratory and the test capability of the laboratory was assessed by the z-score method. By means of method experiments and records, the reasons of dissatisfaction and the influencing factors of the results were discussed. Results: The statistic of the homogeneity of urine arsenic samples was less than the critical value (P>0.05) , which showed that the arsenic in the sample was homogeneous. The satisfactory rate of comparison between 36 laboratories was 86.1%. The main reasons for dissatisfaction were the testing conditions and the quality control measures. The selection of sample pretreatment, acidity control and hydrogenation conditions was the main influencing factor for the determination of urinary arsenic by atomic fluorescence spectrometry. Conclusion The level of urinary arsenic detection in the occupational health laboratories was generally better and a few laboratories need to be improved ability of detection. It was very important to control the test conditions reasonably and strengthen the quality control measures to improve the accuracy of urine arsenic detection.

Objective: To optimize the ion selective electrode method of measuring urinary fluorine in WS/T 30-1996. Methods: The volume of 5 mol/L NaOH solution was fixed to confect the TISAB buffer solution. The samples were prepared by mixing 5 ml urine and equal volume of TISAB solution. Fluorine electrode and calomel electrode was used to test.

Objective To investigate the effects and the mechanism of thrombospondin 4 (Thbs4) gene-edited bone marrow mesenchymal stem cells (BMSCs) transplantation on vascular endothelial growth factor (VEGF) and angiopoietin-1 (Ang-1) in diabetic rats with hind limb ischemia. Methods Thirty Sprague-Dawley rats were randomly divided into the model group, BMSCs treatment group and Thbs4-BMSCs treatment group on average. After constructing the typeⅡdiabetic rat model with hind limb ischemia, 100μl normal saline, BMSCs suspension and Thbs4-BMSCs suspension (cell number: 2×106) were locally injected into the ischemic injury area of rats for the model group, BMSCs group and Thbs4-BMSCs group, respectively. The rats were sacrificed on the 14th day after stem cell transplantation, and the muscle tissues near the ischemic area were collected. The relative expression of VEGF and p-Smad2/3 protein was detected by Western Blot. The Ang-1 protein expression was detected by immunofluorescence staining. The levels of related genes were detected by qRT-PCR, and the von Willebrand Factor (vWF) protein expression was detected by immunohistochemistry staining. Results The relative expression levels of VEGF, Ang-1 and vWF protein in the Thbs4-BMSCs group were significantly higher than those in the model group and BMSCs group (VEGF protein:P<0.01 and P<0.05). The mRNA expression of VEGF and Ang-1 were significantly up-regulated, the differences were statistically significant(VEGF mRNA:all P<0.01;Ang-1:P<0.01 and P<0.05). The expression of p-Smad2/3 protein in the Thbs4-BMSCs group was significantly higher than that in the model group and the BMSCs treatment group (all P<0.01). The expression of p-Smad2/3 protein was significantly decreased after the addition of p-Smad2/3 pathway inhibitor, the differences were statistically significant (P<0.05). Conclusions Thbs4-BMSCs transplantation can effectively promote angiogenesis in diabetic rats with hind limb ischemia, and the effect of angiogenesis may be related to the activation of Smad2/3 signaling pathway.

Objective: To explore deep vein thrombosis (DVT) occurrence in patients after right heart catheterization and the effect of anticoagulant therapy. Methods: A total of 171 consecutive patients with electrophysiological study (EPS) and/or radiofrequency catheter ablation (RFCA) in our hospital from 2015-01 to 2016-05 were enrolled. All patients had supra-ventricular tachycardia and completed a venous surgery, they were randomly divided into 2 groups: Anticoagulation group,n=87 and Non-anticoagulation group,n=84. Lower extremity vascular Doppler ultrasonography was performed at (24-48) h post-operation to compare the incidence of DVT between 2 groups. Results: There were 13/171 patients were excluded for not completing post-operative lower extremity vascular Doppler ultrasonography including 9 patients in Anticoagulation group and 4 in Non-anticoagulation group. 158 patients finished post-operative examination and follow-up study. Anticoagulation group had 7/78 (8.97%) patients suffered from DVT, Non-anticoagulation group had 41/80 (51.3%) patients suffered from DVT,P<0.001. Conclusion: The incidence of DVT was higher after right heart catheterization without anticoagulation; heparin treatment may reduce DVT occurrence in relevant patients.
