文题释义:
人类辅助生殖技术:指采用医疗辅助手段使不育夫妇妊娠的技术,包括人工授精和体外受精-胚胎移植及其衍生技术两大类。
体外生殖培养液:是含有能量成分、渗透压调节成分、酸碱度调节成分、氨基酸、生长因子等,保证生殖细胞在体外可以存活并成长的一种培养液。不同的体外生殖细胞使用不同的培养液,在不同的生长阶段,也会使用不同的培养液,因此体外生殖培养液的成分对最终体外生殖手术的成功率有很大影响。
 
 
背景:目前,对于体外生殖培养液的质量控制文件或技术标准中,对成分含量指标及检测方法未做明确规定,为保证该类产品的安全有效性,应及早建立质量标准。
目的:采用液相质谱联用法检测体外生殖培养液中18种氨基酸指标成分,分析不同用途培养液中18种氨基酸的含量。
方法:采用超高效液相色谱三重四级杆质谱联用法,检测体外生殖培养液中18种氨基酸(甘氨酸、亮氨酸、蛋氨酸、酪氨酸、组氨酸、苏氨酸、丙氨酸、异亮氨酸、色氨酸、胱氨酸、赖氨酸、天门冬氨酸、缬氨酸、苯丙氨酸、脯氨酸、丝氨酸、谷氨酸、精氨酸)指标成分,色谱柱为SUPELCO Discovery HS F5-3(15 cm×    2.1 mm,3 μm),流动相为0.1%甲酸水溶液-0.1%甲酸乙腈溶液,梯度洗脱,流速0.35 mL/min,柱温40 ℃;质谱采用电喷雾离子源,负离子模式扫面,扫描方式为多反应监测。

结果与结论:18种氨基酸在0.25-12.5 mmol/L浓度范围内线性关系练好;18种氨基酸的平均加样回收率在86.3%-125.3%之间,精密度实验与重复性实验的相对标准偏差均小于4.7%,说明采用液相质谱联用法检测体外生殖培养液灵敏、快速、准确、专属性强,可为体外生殖培养液的质量标准研究提供依据。

Abstract:

BACKGROUND: At present, in the quality control file or technical standards of in vitro fertilization medium, indicators for component contents and detection methods have not yet been defined. To ensure the safety and effectiveness of these products, we should try to establish and improve the quality standards.

OBJECTIVE: To establish a method for simultaneously testing 18 kinds of amino acids by ultra-high performance liquid chromatography–tandem mass-spectrometry (UHPLC-MSMS), and to analyze the difference in the content of different amino acids in the medium for different uses.
METHODS: Using the UHPLC-MSMS, we detected the indicator components of 18 different amino acids in the in vitro fertilization medium. These amino acids included glycine, leucine, methionine, tyrosine, histidine, threonine, alanine, isoleucine, tryptophan, cystine, lysine, aspartic acid, valine, phenylalanine, valine, serine, glutamic acid, arginine. The UHPLC separation was performed on a SUPELCO Discovery HS F5-3 column (15 cm×2.1 mm, 3 μm) in a gradient elute mode with acetonitrile and water (both containing 0.1% formic acid) as the mobile phase at a flow rate of 0.35 mL/min. The column temperature was 40 ℃. MS detection was performed with multiple-reaction monitoring mode using negative electro spray ionization.

RESULTS AND CONCLUSION: The linearity was achieved in the range of 0.25-12.5 mmol/L for the 18 different amino acids. The average recovery rate of these amino acids ranged 86.3% to 125.3%. The relative standard deviation of the precision experiment and the repeatability experiment was less than 4.7%. These findings indicate that this is a sensitive, rapid, accurate, and specific method that can be used for the quality control of in vitro fertilization medium.
