A new method for O-ethyl S-[2-( diisopropylamino) ethyl] methylphosphonothiolate ( VX) , sarin detection and its kinetic analysis based on piezoresistive microcantilever aptasensor was developed, where VX, sarin aptamers were immobilized on the microcantilever surface by biotin-avidin binding system. A linear relationship between the response voltage and the concentration of VX in the range of 2-60μg/L was obtained. The linear regression equation was △Ue=0. 886C-1. 039 (n=5, R=0. 984, p<0. 001) and the detection limit was 2μg/L ( S/N≥3 ) . A linear relationship between the response voltage and the concentration of sarin in the range of 10-60 μg/L was obtained, the linear regression equation was △Ue=0. 716C-2. 304 ( n=5, R=0 . 996 , p<0 . 001 ) and the detection limit was 10 μg/L ( S/N≥3 ) . The sensor showed no response for O-butyl methylphosphonochloridate, a structural analog of VX and sarin, which indicated high specificity and good anti-interference ability. On this basis, a reaction kinetic model based on receptor-ligand binding and the relationship with output voltage change was established. Response voltage (△Ue ) and response time( t0 ) were obtained from the fitting equation on different concentrations of VX, sarin fitted well with the measured values.

The paper is to report the pharmacokinetics of furosemide in rats living at plain area and high altitude. After intragastric administration of furosemide (2.87 mg x kg(-1)), serial blood samples (0.5 mL) were collected by retro-orbital puncture at 0, 20 min, 40 min, 1, 1.5, 2, 3, 4, 6, 8, 12 and 24 h, samples were determined by LC-MS/MS, and plasma concentration-time data were analyzed by DAS 2.0 software to get the related pharmacokinetic parameters. The main pharmacokinetic parameters: area under curve (AUC), mean residence time (MRT), the biological half-life (t1/2) and the peak concentration (C(max)) of furosemide, were significantly increased at high altitude, the time to reach peak concentration (t(max)) and clearance (CL) was significantly decreased. This study found significant changes on the pharmacokinetics of furosemide under the special environment of high altitude. This finding may provide some references for clinical rational application of furosemide at high altitude.

Objective To evaluate the short-term efficacy, safety and effectiveness of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) combined with radioactive 125I seed implantation in treating advanced non-small-cell lung cancer (NSCLC). Methods A total of 48 patients with inoperable and EGFR mutation-positive advance NSCLC were included in this study. The patients were divided into study group (n = 26) and control group (n = 22). Patients in the study group were treated with EGFR-TKIs combined with radioactive 125I seed implantation; while patients in the control group only received EGFR-TKIs treatment, which was kept on until the disease progressed. The clinical efficacy, and the incidence of side effect as well as the survival rate were determined, and the results were compared between the two groups. Results Local disease control rate of the study group and the control group was 92.3% and 68.2%respectively, the difference was statistically significant (P= 0.033), while the effective rate was 76.9% and 54.5%respectively, the difference was not significant (P=0.101). Progression-free survival (PFS) time of the study group and the control group was 14.1 months and 9.7 months respectively (P< 0.05). The one-year survival rate of the study group and the control group was 80.8%and 63.6%respectively (P<0.05), and the median survival time was 26.9 months and 17.1 months respectively (P < 0.05). The major complication caused by radioactive 125I seed implantation was pneumothorax. Conclusion For EGFR mutation-positive advance NSCLC, EGFR-TKIs together with radioactive 125I seed implantation is a safe and effective treatment.Its short-term efficacy is superior to pure EGFR-TKIs therapy. At present, this combination therapy is a new alternative for the treatment of EGFR mutation-positive advance NSCLC.

A new magnetic affinity immunoassay (MAIA) strategy based on enzyme-labeled phage displayed antibody was developed. The assay consisted of a sandwich format in which immobilized polyclonal antibody (pcAb) on magnetic microparticle was used for capture probe, and enzyme-labeled phage displayed antibody for specific detection probe to increase enzyme amount and enhance detection signal. By the proposed method,β-bungarotoxin (β-BGT) was successfully detected. A linear relationship between absorbance value and the concentration of β-BGT in the range of 0. 016-62. 5 μg / L was obtained. The linear regression equation was Y=0. 641X+1. 355 (R =0. 9925, n = 13, p<0. 0001) with a detection limit of 0. 016 μg / L. In comparison with the traditional ELISA, this method gave a 10-fold better sensitivity in β-BGT detection. This strategy also gave a 4-fold better sensitivity comparing with the MAIA based on enzyme labeled monoclonal antibody (mcAb). Due to low detection limit, acceptable reproducibility and high specificity, this method holds great promise in toxin trace detection.
