A method for determining volatile organic compounds (VOCs) emitted from medical molecular sieve oxygen concentrators was developed using thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS). The oxygen concentrator gas was sampled at a flow rate of 0.5 L/min through a branched sampling system onto Tenax GR/carbopack B adsorption tubes. The adsorbed compounds were desorbed and introduced using a programmed temperature vaporization inlet system, followed by chromatographic separation on an SH-I-624Sil MS column. Four VOCs (BHT-Q, PTBP, BHT-quinol, and EHB) were detected in the medical oxygen concentrator using this method. Calibration curves for these compounds exhibited excellent linearity ( R ²>0.99) within the range of 3~100 ng. With a sampling volume of 20 L, the detection limit of the four VOCs ranged from 0.003 9 to 0.022 2 μg/m ³. Spike recovery rates for the four VOCs were between 95% and 115%, with relative standard deviations (RSDs) below 5% ( n=6). The method is simple, rapid, highly sensitive, and accurate, making it suitable for VOCs detection in medical molecular sieve oxygen concentrators.

【Objective】 To study the frequency, Rh phenotypes and molecular & biological background of D-elute (D^el) phenotype in RhD-negative blood donors in Dalian. 【Methods】 A total of 355 serologically RhD-negative samples between November, 2018 and October, 2019 in Dalian Blood Center were collected, and tested for RhC, c, E, e phenotypes using monoclonal antibodies and anti-D adsorption/elution test. DNA was extracted by magnetic bead selection. RHD 1227G>A mutation was detected by melting curve analysis. All RHD exons were sequenced by Sanger sequencing. 【Results】 Among 355 serologically RhD-negative blood donors, 55 (15.5%) were identified as D^el and the remaining 300 cases (84.5%) were true RhD negative. Ccee (45/55, 81.8%) was the predominant Rh phenotype among 55 D^el cases while ccee (210/300, 70.0%) was the most prevalent Rh phenotypes in 300 true RhD negative cases. In 55 D^el cases, 51 (92.7%) had RHD 1227G>A mutation, and the other 4 cases(7.3%) had mutations in other sites. 【Conclusion】 The frequency of D^el was 15.5% in serologically RhD-negative blood donors in Dalian, with Ccee being the most prevalent Rh phenotype and RHD 1227G>A the most common gene mutation.

BACKGROUND:Nowadays, the component content of assisted reproductive culture medium and their test methods are unclear in the quality standards. We need to establish the test methods to fil this vacancy, so as to control the quality of assisted reproductive culture medium effectively. OBJECTIVE:To establish an evaluation method for determination of fructose and glucose in assisted reproductive culture medium, thereby based on which to establish the quality standards. METHODS:High performance liquid chromatography-differential refractive index detector was adopted and Rezex RCM-Monosaccharide Ca2+(8%) (300.0 mm×7.8 mm) column was used. The mobile phase was ultrapure water at the flow rate of 0.6 mL/min and the temperature of 80 ℃. RESULTS AND CONCLUSION:Resolution of the peaks of glucose and fructose was 3.2. The linear ranges of glucose and fructose were 30.1-502 mg/L (r=0.999 8) and 102-408 mg/L (r=0.999 8), respectively. The relative standard deviation of reproducibility test was 0.17%and 0.40%, respectively. The relative standard deviation of stability test was 0.22%and 0.73%, respectively. The glucose group and fructose group average recovery rates were 1.22%and 1.38%, respectively. The methodology of High performance liquid chromatography-differential refractive index detector accorded with the requirements. The glucose contents of samples 1 and 2 were 96.7 mg/L and 99.6 mg/L, respectively. The fructose contents of samples 1 and 2 were 208.5 mg/L and 197.4 mg/L, respectively. A reliable, simple, and accurate method was provided for the quality control of assisted reproductive culture medium, which fil s the domestic vacancy in the quality standards for assisted reproductive culture medium.
