Objective To explore the impact of atrial fibrillation (AF) recognized at primary diagnosis on clinical features and outcomes of patients with AF in emergency service.Methods Data were collected from consecutive patients admitted in resuscitation room in the Department of Emergency (ED) of a major comprehensive teaching hospital,from January 1,2011 through December 31,2015.Patients were checked by electrocardiogram examination and / or monitored in resuscitation room after admission,and were divided into patients with AF recognized at a primary diagnosis and those with AF judged by alternative primary diagnoses in ED.The main criteria of prognosis were the length of resuscitation room stay,number of repeated ED visits,and outcome scale (such as death,transferred to intensive units,transferred to general wards,or direct discharge).Non-paired student t test,x2,and circular distribution analysis were performed using SPSS 10.0 and EXCEL 2007 software.Results A total of 929 patients with mean age of (70.3 ± 12.7) years,and 502 (54.0％) female were enrolled.There were 122 cases with AF not recognized at primary diagnosis but by an alternative primary diagnosis (non-primary group,NPG),and 807 cases with AF recognized at primary diagnosis (primary group,PG).Compared with the PG,the patients were older [(76.9 ±9.3) vs.(68.7 ± 14.4),P ＜0.01],had more comorbidities [(1.75 ± 1.26) vs.(0.08±0.39),P＜0.01],higher APACHE Ⅱ scores [(17.89±8.19) vs.(8.64±4.15),P＜ 0.01],longer resuscitation room stay (P ＜ 0.01),higher mortality (11.5％ vs.0.2％,OR =52.176,95％ CI:11.698-232.710,x2 =78.928,P ＜ 0.01) and a higher percentage of transferring to intensive careunit (14.8％ vs.5.1％,OR=3.234,95％CI:1.791-5.838,x2 =16.674,P＜0.01) in NPG.There were no significant difference in number of repeated-visits in ED between the PG and the NPG.Conclusion Patients with AF in the ED judged by alternative primary diagnosis are older and have more comorbidities,higher mortality and higher probability to be transferred to intensive care unit than patients with AF directly recognized by a primary diagnosis.This cohort of patients with special characteristics should be meticulously cared for and be distinguished from the patients with AF crystal clear at a primary diagnosis.Future studies are needed to examine the specific impact of AF on outcomes in the setting of primarydiagnoses in ED.

Objective:A method that is based on microfluidic cell chip technology was developed for the first time to analyze CD14+monocyte myeloperoxidase (MPO) expression in myelomonocytic leukemia (M4) patients. CD14+monocyte MPO expression in M4 patients was preliminarily discussed. Methods:a. The chip was prepared by using polydimethylsiloxane as the host material and by secondary foam molding. b. A total of 48 clinically diagnosed M4 patients and 52 patients with normal myelogram were included as the test and control groups, respectively. c. A method based on the microfluidic cell chip approach was established to detect CD14+mono-cytes and to determine the positive rate and degree of MPO expression in the cells. d. The microfluidic cell chip technique was used to compare CD14+monocyte MPO expression in M4 patients with that in the control. Results:a. The designed microfluidic single cell analysis chip allowed the entry of granulocytes into the corresponding microfluidic channels. Thus, blood cells were separated. Numer-ous ghost corpuscles surrounded the separated white blood cells (WBCs). WBC morphology did not show obvious changes. b. The posi-tive rate of MPO expression and the activity of CD14+monocytes in the bone marrow of M4 patients were significantly higher than those in the bone marrow of the control (P<0.05). Conclusion:A method based on microfluidic single cell technology was developed for the first time to analyze the MPO expression in CD14+monocytes. CD14+monocyte MPO activity in M4 patients was significantly higher than in the control. CD14+monocyte MPO activity can be used as an auxiliary examination marker for clinical diagnosis.

Objective To investigate the intensive atorvastatin therapy on B7-H4 in peripheral blood monocytes of patients with unstable angina PCI undergoing percutaneous coronary intervention. Methods 80 patients with unstable angina were randomized to pretreatment with intensive dose (80 mg/day ,n = 40) and conventional dose(20 mg/day,n=40)of atorvastatin. Peripheral blood were subsequently obtained prior to PCI,and 18 ~ 24 h after PCI. Peripheral blood serum level of IL-4,IL-10 and IFN-γ were quantified using enzyme-linked immunosorbent assays. Fluorescence-based quantitative real-time PCR was used to measure levels of periph-eral blood monocytes B7-H4 mRNA. Results Levels of IL-10 ,sB7-H4 and B7-H4 mRNA increased in patients of both groups after PCI. The increase in intensive dose group is more significant (P < 0.05). IL-4 and IFN-γ decreased in patients of both groups after PCI. The decrease in intensive dose group is more significant (P <0.05). Conclusion Intensive dose atorvastatin treatment improve post-PCI immune inflammation in patients with unstable angina,possibly by promoting the expression of B7-H4 in peripheral blood monocytes.
