Objective To investigate whether echocardiography left ventricular ejection fraction (LVEF) and NT-proBNP could be an early detective marker for patients with untypical NSTE-ACS. Methods A total of 248 ACS cases admitted to the emergency department of our hospital from January 1,2015 to June 31,2016 were retrospectively reviewed. The data included age,gender,past medical history,D-dimer,MB isoenzyme of creatine kinase(CK-MB),cardiac troponin I(cTnI),the precursor of the N-terminal pro-brain natriuretic peptide(NT-proBNP),electrocardiogram(ECG)before treatment,and the CK-MB,cTnI and LVEF,the treatment of percuta-neous coronary intervention(PCI)or thrombolytic by drugs. Survival condition and time from onset to death were recorded. According to the results of multivariate logistic regression analysis ,receiver operating characteristic curve(ROC curve)and fitting curve were drawn. The association between the LVEF and NT-proBNP before the treatment and prognosis of ACS was analyzed. Results NSTE-ACS patients with chief complaint of chest pain were less than those of STE-ACS(33.6% vs. 70.1%,P=0.003). Pre-hospital time was longer than that of STE-ACS group(67.92 ± 116.89 vs. 30.65 ± 55.59,P = 0.006). CTNI(4.37 ± 12.53 vs. 9.62 ± 18.00,P=0.011)and LVEF(53.51 ± 14.51 vs. 56.26 ± 12.30,P=0.019)were less than that of the STE-ACS group. NT-proBNP was higher than that of the STE-ACS group(2288.37 ± 4612.10 vs. 1506.84 ± 1722.51,P=0.038). mortality rates was higher than the STE-ACS group((15.3%vs. 6.8%,P=0.036). Multivariate logistic regression analysis showed that LVEF values was correlated to 28-day death(B =-0.097 ,P=0.022). The ROC curves showed that LVEF values was negative correlated with the 28-day death. However,combination of LVEF and NT-proBNP was better than single LVEF values. LVEF values was negative correlated with the NT-proBNP(r =-0.263,P=0.001), LVEF values had greater and longer survival time(B=0.401,P=0.045)but NT-proBNP was not related to surviv-al time.(B=0.00,P=0.931). Conclusion LVEF and NT-proBNP are correlated with the early risk assessment of patients with ACS,but was not correlated with the time from onset to death. The decrease in LVEF values at the early stage of NSTE-ACS may be helpful to indicate the critical condition of the ACS patients.

BACKGROUND:Currently, there is a lack of efficient, non-invasive way to transplant stem cels to the target organ or tissue. Exploring a way to guide targeting transplantation of stem cels and to improve the efficiency of stem cel homing is now one of focuses in the field of stem cels research.
OBJECTIVE: To establish a simple and feasible method to chemicaly modify the cel surface using biotin-streptavidin reaction system, and to evaluate the efficiency of this method to label bone marrow mesenchymal stem cels (BMSCs) and its effects on cel biological functions.
METHODS: Passage 3 BMSCs were obtained by whole bone marrow culture method and verified by flow cytometry. Biotin, streptavidin, sulfonated biotin-N-hydroxy-succinimide were used to equip the adhesion molecule ligand, sialyated LewisX (SLeX), to the BMSCs surface. The labeling rate of BMSCs was assessed using fluorescence microscope, the vitality of BMSCs was evaluated by trypan blue staining, and the proliferation of BMSCs was evaluated by cel counting kit-8 assay. Adipogenic and osteogenic inductions were used to evaluate the effect of the method on the multi-differentiation function of BMSCs.
RESULTS AND CONCLUSION: After culture for 2 weeks, passage 3 BMSCs were obtained and confirmed by expressing CD90, CD29 and lack of CD34, CD45. Biotin, streptavidin, sulfonated biotin-N-hydroxy-succinimide were successfuly used to equip sialyated LewisX (SLeX) to the BMSCs surface and had minor effects on the vitality, proliferation, and differentiation of BMSCs. This method was simple for surface modification and had a high modification rate of 88%. The homing of BMSCs modified by this method to the target organ or tissue could be greatly enhanced. Therefore, this method potentialy could have extensive and important applications.
