Coronary artery disease (CAD) is a multifactorial disease in which inflammation plays a central role.This study aimed to investigate the association of inflammatory markers such as the neutrophil to lymphocyte ratio (NLR),the Global Registry of Acute Coronary Events (GRACE) score with in-hospital mortality of elderly patients with acute myocardial infarction (AMI) in an attempt to explore the prognostic value of these indices for elderly AMI patients.One thousand consecutive CAD patients were divided into two groups based on age 60.The laboratory and clinical characteristics were assessed retrospectively by reviewing the medical records.The NLR and GRACE score were calculated.In the elderly (≥60 years),patients with non-ST-elevation myocardial infarction (NSTEMI) and ST-elevation myocardial infarction (STEMI) had significantly higher NLR than did those with unstable angina (UA) and stable angina pectoris (SAP) (P＜0.01).The NLR was considerably elevated in older AMI patients compared with their younger counterparts (＜60 years) (P＜0.05).In elderly AMI patients,the NLR was considerably higher in the high-risk group than in both the low-risk and medium-risk groups based on the GRACE score (P＜0.05 and P＜0.01,respectively),and the NLR was positively correlated with the GRACE score (r=0.322,P＜0.001).Either the NLR level or the GRACE score was significantly higher in the death group than in the surviving group (P＜0.05).By curve receiver operator characteristic curve (ROC) analysis,the optimal cut-off levels of 9.41 for NLR and 174 for GRACE score predicted in-hospital death [ROC area under the curve (AUC) 0.771 and 0.787,respectively,P＜0.001].It was concluded that an elevated NLR is a potential predictor of in-hospital mortality in elderly patients with AMI.

AIMTo study the bioactive constituents from the flower of Castanea mollissima Blume.

METHODSCompounds were isolated and purified by column chromatography on silica gel and polyamide. Structures were determined by various spectroscopic data,including UV, IR, 1H and 13CNMR, EIMS and FABMS, 1H-13C-COSY and HMBC.

RESULTSTwo compounds were isolated from the ethyl acetate fraction of 95% ethanol extract and the structures were elucidated as kaempferol-3-O-[6"-(E)-p-coumaroyl]-alpha-D-mannopyranoside (1) and kaempferol-3-O-[6", 4"-di-(E)-p-coumaroyl]-alpha-D-mannopyranoside (2).

CONCLUSIONCompounds 1 and 2 are new compounds, named castanoside A and B respectirely.

BACKGROUND:Oversize stress of a dental implant and its surrounding tissue is the main factor to affect the
long-term use of dental implants. So, the reasonable and precise design of implant shape is one of the important methods of prolonging the life span of dental implants.
OBJECTIVE:To make the optimal analysis and design of the diameters of connector screw and central screw of the adjustable-angle dental implant invented in the earlier stage.
METHODS: The finite element analysis model of the edentulous mandible with adjustable-angle dental implant was established by software Pro/E 5.0, Mimics 10.0 and ANSYS Workbench 14.5. The maximum equivalent
stress of dental implant-edentulous mandibular model was analyzed.
RESULTS AND CONCLUSION:The maximum equivalent stress of dental implant-edentulous mandibular model

Objective To evaluate the efficacy and safety of adefovir dipivoxil(ADV)in treating patients with hepatitis B e antigen(HBeAg)positive chronic hepatitis B.Methods In this randomized,double blind,placebo-controlled,multicenter trial,210 eligible patients with HBeAg positive chronic hepatitis B were recruited and randomized(randomization ratio was 2:1)receiving ADV 10 mg/d for 48 weeks(ADV+ADV group,n=142)or placebo for 24 weeks followed by ADV 10 mg/d for 24 weeks(PLB+ADV group,n=68).The primary endpoint was virological response. The secondary endpoint was serologic response(HBeAg loss rate and HBeAg seroconversion rate) and alanine aminotransferase normalization rate.Results After 24 weeks therapy,mean reduction of hepatitis B virus(HBV)DNA level comparing with that of baseline was 3.12 log_(10)copy/mL in ADV +ADV group while it was 0.95 log_(10)copy/mL in PLB+ADV group.The percentages of patients with HBV DNA clearance(HBV DNA level

This study was aimed to establish the quantitative analysis of hIL-2 in culture supernatant by multifunctional Luminex 100. The lymphocytes were separated from ACD-anticoagulated peripheral blood by density gradient method. The lymphocytes were stimulated with PHA for 48 hours, and frozen at -20 degrees C The relative fluorescence units of standard preparations and samples were detected by multifunctional Luminex 100, and the sample concentrations were calculated by standard curve. The results indicated that the regression equation of standard preparation is Lg (RFU) = 1.547 + 0.867 LgC. ANOVA F = 301.7427, p < 0.05 (nu = 6). The analysis of variance showed F = 301.7427, p < 0.05 (nu = 6). The test of regression coefficient showed t = 17.3707 (nu = 6), p < 0.05. It is concluded that method for induction and measurement of human IL-2 in vitro is established. The standard curve established by this way is statistically significant. There is linear relationship between the concentration of hIL-2 and fluorescence intensity.
