Objective To verify and monitor the performance of accuracy, precision and comparability of 26 clinical biochemical analytes (29 methods) in the six centers involved in multi-centers reference intervals research, and to ensure the reliability of theirmeasurement results.Methods During the period of the systems evaluating, two levels of commercial quality control materials and fresh frozen human serum reference materials were applied to verify the performance of inter-laboratory precision and accuracy of analysis systems. During the period of samples testing, the commercial quality control materials were measured whenever samples were analysed, the fresh frozen serum reference materials were measured once a month.The coefficient of variations (CVs), bias and total errors were calculated to assess the precision, accuracy and comparability.Results Verification of precision and accuracy: ( 1 ) the ranges of CVs of 29 methods in the six laboratory laboratories were 0.4%-6.0%, the CVs of all 29 methods met the criterion . (2) The overall average bias of the analysis systems of 21 analytes (24 methods) ranged from -5.15%( ALT) to 4.46% ( Ur ) .Among 24 methods the overall average bias of TP, Glu-GOD, Ur, Cl, Ca exceeded the acceptable range.The quality assessment during the period of samples testing:(1) The overall average bias ranged from -1.95%(Ca) to 2.92%(Ur), median 1.26%, they all met the requirements of relevant standards.( 2 ) When commercial control materials were tested, the requirements of CVs were fulfilled for most methods in the six laboratories,and the CVs of TP, Alb, Cl, Ca exceeded the acceptable range.The overall average TE of all methods met the quality specification for the C-N controls material.For the C-P control material, only the overall average TE of TP (5.05%) exceeded thearceptable range while the other methods met the requirement in criterion.Conclusions The performance of precision and accuracy of the analysis systems used in the six laboratories passed the verification.During the period of sample testing, the performance of precision and accuracy of the most methods in the 6 laboratories met the requirements of quality specifications, and the overall performance was good.Because of the limitation of current technology the performance of some methods didn't fulfill the requirement of specifications, and need to be improved.

Objective:To study the changes the changes of cytokine expression the aqueous humor of patients with macular edema secondary to branch retinal vein occlusion (BRVO-ME) before and after intravitreal ranibizumab (IVR).Methods:A prospective clinical study. From June 2018 to June 2021, 31 eyes of 31 patients with non-ischemic BRVO-ME diagnosed by ophthalmic examination in Department of Ophthalmology, Beijing Hepingli Hospital were included in the study. Among them, 15 males had 15 eyes, and 16 females had 16 eyes. Age was 70 (65, 72) years; the course of disease was 10 (9, 15) days. All of them were first-time patients. All eyes were treated with IVR once a month for 3 consecutive months. At the end of each IVR treatment, 0.1 ml aqueous humor was extracted immediately. The concentrations of vascular endothelial growth factor (VEGF), interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in aqueous humor were detected by flow cytometry. The concentrations of cytokines in aqueous humor before and after treatment were compared by Kruskal-Wallis or Wilcoxon signed-rank test. Spearman correlation analysis was performed on the correlation between VEGF and MCP-1 expression level in aqueous humor before treatment.Results:The concentrations of VEGF and ICAM-1 in aqueous humor were significantly lower at 1 month after treatment compared with that before treatment, and at 2 months after treatment compared with that at 1 month after treatment ( Z=4.03, 3.25, 2.50, 3.48; P<0.05); the concentrations of IL-6 and VCAM-1 increased and the concentration of MCP-1 decreased, but there was no significant difference ( Z=-0.21, 1.42, 0.86, -0.53, 0.92, -1.57; P>0.05). Spearman correlation analysis showed that there was a strong positive correlation between VEGF and MCP-1 in aqueous humor before treatment ( r=0.78, P<0.001). Conclusion:The concentrations of VEGF and ICAM-1 in aqueous humor significantly decrease after IVR treatment in BRVO-ME; the concentrations of IL-6, MCP-1 and VCAM-1 do not obviously change.
