方法血浆样品经甲醇沉淀蛋白后,以3种抗生素的稳定性同位素(ETP-D4、IPM-D4、MEM-D6)为内标,采用ACQUITY UPLC BEH C18(2.1 mm×50 mm,1.7μm)色谱柱分离;流动相为98%乙腈+2%水+0.1%甲酸和98%水+2%乙腈+0.1%甲酸,梯度洗脱;流速为0.3 mL/min;柱温为40 ℃;采用正离子、多反应监测模式进行扫描分析。
结果该方法专属性良好,在ETP、IPM、MEM 0.2~200、0.1~100、0.1~100μg/mL范围内线性良好(r2≥0.993),批内、批间精密度和准确度良好(RE均≤5.14%,RSD均≤11.15%),基质效应、提取回收率较一致(RSD≤12.99%)。
结论本实验建立了一种可以同时定量ETP、IPM、MEM血药浓度的UPLC-MS/MS法,该方法样品前处理简单、检测时间短、所需样品量少,可满足临床需求。

First Central Clinical College of Tianjin Medical University,Tianjin 300192,China;2. Dept. of Pharmacy,Tianjin First Central Clinical Hospital,Tianjin 300192, China)ABSTRACT OBJECTIVE To establish a UPLC-MS/MS method for the determination of plasma concentration of three carbapenem antibiotics,i.e. ertapenem (ETP),imipenem (IPM)and meropenem (MEM).METHODS After protein precipitation with methanol,the plasma samples were separated by ACQUITY UPLC BEH C18column (2.1mm×50mm,1.7μm)using stable isotopes of three antibiotics (ETP-D4,IPM-D4,MEM-D6)as the internal standard. The mobile phases were 98%acetonitrile +2% water +0.1%formic acid and 98%water +2%acetonitrile +0.1%formic acid,by gradient elution. The flow rate was 0.3mL/min and the column temperature was 40 ℃. Scanning analysis was performed in the positive ion and multiple reaction monitoring mode. RESULTS The method had good specificity,good linearity (r2≥0.993)in the range of 0.2-200,0.1-100and 0.1-100μg/mL of ETP,IPM and MEM,and good intra-batch and inter-batch precision and accuracy (all RE≤5.14%,all RSD≤11.15%),the matrix effect and extraction recovery were consistent (RSD≤12.99%). CONCLUSIONS This study establishes the UPLC-MS/MS method to simultaneously quantify the plasma concentration of ETP,IPM and MEM. The method has the advantages of simple pretreatment, short detection time and small sample quantity to meet clinical requirement.KEYWORDS carbapenem antibiotics; UPLC-MS/MS; plasma concentration; ertapenem; imipenem; meropenem碳青霉烯类抗生素具有抗菌谱广、抗菌活性强、耐药率低的特点,已成为治疗重症感染的主要选择。

但对于白血病/淋巴瘤免疫分型,国际上迄今为止也没有统一的抗体组合。
在2000年国际细胞分析学会(ISAC)大会上,临床血细胞计数协会组织了一次国际专家会议,以期对检测血液淋巴系统肿瘤所需最少、最有效的单抗数达成共识。
75%与会者一致认为,对于慢性淋巴系统增殖性疾病(CLD)有9种单抗:CD5,CD19,κ,λ,CD3,CD20,CD23,CD10,CD45对初诊来说是最基本的。
淋巴瘤和CLD相似,需要至少12-16种单抗。
对于急性白血病(AL),75%的与会者认为大约13-15种单抗是最基本的:CD10,CD19,CD79a,CD13,CD33,CD34,CD45,CD2,MPO,CD7,CD14,CD3,HLA-DR等,对初步鉴别白血病系列是必需的。
其他一些(CD16,CD56,CDw65,TdT,cyCD3)可能对某些病例有用。
几乎所有的投票者都认为,要对急性白血病完善分类所需单抗的恰当数量平均为20-24种。
但这些抗体之间组合也是一大难题,目前也无统一规定(如表二)。
大会多数发言者(11/13)指出,对已确诊病人的监护和分期来说,仅需较少单抗。
抗体的质量控制是实验的关键环节。
抗体的质量包括其特异性、灵敏度、精密度。

Methods We selected 200 patients with suspected diabetes who were admitted to Xia‐men Haicang Hospital from January 2020 to December 2021 as the research object, and took the oral glucose toler‐ance test as the diagnostic gold standard. Serum C-peptide test and Glycated hemoglobin test were performed on thepatients, and the results of serum C-peptide, serum C-peptide and Glycated hemoglobin test were compared betweenthe two groups. Results Among 200 suspected diabetes patients, 180 patients were diagnosed by Glucose tolerancetest, accounting for 90.00%. The positive detection rate was 98.33% (177 cases) by serum C-peptide test, and 86.11% (155 cases) by serum C-peptide combined with Glycated hemoglobin test. The sensitivity, specificity, and accuracy of combined detection were better than those of single detection, and the difference was statistically significant (P <0.05).Conclusion Serum C-peptide combined with Glycated hemoglobin test can improve the accuracy of clinical diagnosis of diabetes and provide more scientific reference for clinical diagnosis.[Key words ] Serum C-peptide; Glycosylated hemoglobin; Diabetes; Diagnosis; Accuracy; Combined test糖尿病是常见的慢性代谢性疾病,主要因为胰岛素代谢紊乱而引起的代谢性疾病,按照疾病成因,可分成1型糖尿病和2型糖尿病两种类型。
