Based on the analysis of Language Learning Strategies of foreign language learners and their characteristics,this paper illuminates that training on Language Learning Strategies in regular language classes helps foreign language learners become successful and independent learners.

Objective To investigate psychological pressure sources of emergency nurses who were assigned to emergency intensive care unit(EICU)and put forward countermeasures.Methods We collected data by phenomenological method of qualitative study.Thirteen nurses who had worked in EICU for at least six months were interviewed.The collected data we analyzed by Colaizzi analysis method.Result The psychological pressure had its sources from 4 main aspects: nursing skills,increasing labor intensity,communications with patients and shortage of staff.Conclusion Nursing administration should actively take measures to relieve the psychological pressures of the emergency nurses who were assigned to EICU so as to improve the nurses’working enthusiasm and the nursing quality of EICU.

B cells play a central role in the pathogenesis of rheumatoid arthritis(RA) through multiple mechanisms.Clinical trials have demonstrated that anti-CD20 monoclonal antibody(Rituximab) is effective and safe to treat refractory RA through depletion of B cells.Rituximab is now approved by FDA for use concurrently with methotrexate to treat RA in patients who have an inadequate response to one or more tumor necrosis factor inhibitors.

Objective To investigate the efficacy and mechanism of Tanshinone ⅡA for treatment on acute cerebral infarction(ACI). Methods 104 patients with ACI were randomly divided into Tanshinone group (50 cases) and control group (54 cases),and were treated with conventional therapy. While,Tanshinone ⅡA was added by intravenous drop in Tanshinone group for 2 weeks. Neurological functional deficit scores,Barthel index(BI) were observed,the levels of serum superoxide dismutas(SOD),lipid peroxide (LPO) and malondialdehyde (MDA) were detected pre and post treatment. The efficacy was compared in the two groups.Results After 2 weeks of treatment,the score of National institute of health stroke scale (NIHSS) was decreased,BI was increased,the level of serum SOD was increased,the levels of serum LPO and MDA were decreased in the two groups. Compared with those in pre treatment,the changes of all the targets were significantly different (all P

Objective To investigate the role of TRAF2 in AP-1 signaling pathway of human B cells.Methods Human Ramos B cells were transfected with plasmids expressing YFP fusion wild type TRAF2(YFP-WT-TRAF2) or YFP fusion dominant-negative TRAF2(DN-TRAF2),or transfected with shRNA-TRAF2 and control shRNA plasmid.After incubation overnight,cells were either sorted with flowcytometry or screened by antibiotics G418.Activation of AP-1 pathway,including phosphorylation of ERK,JNK and P38,as well as nuclear translocation of AP-1 subunits were detected by western blot and ELISA.Results Overexpression of WT-TRAF2 selectively induced activition of MAPK by phosphorylation of ERK and P38,and further induced nuclear translocation of C-FOS.Moreover,both overexpression of DN-TRAF2 and transfection of shRNA-TRAF2 inhibited phosphorylation of ERK and P38,and nuclear translocation of C-FOS.Conclusion TRAF2 selectively activates some kinases in CD40 mediated AP-1 signaling pathway,and plays an important role in AP-1 activation.

ObjectiveTo investigate the diagnostic and prognostic significance of serum human kallikrein11 ( KLK11 ) in patients with ovarian cancer. MethodsThe level of serum KLK11 was determined by enzyme-linked immunoassay(ELISA) for 30 patients with ovarian cancer, 26 patients with benign gynecologic processes and 32 healthy subjects,and the KLK11 value beyond the upper-limit of 95％ credibility interval( 95％ CI) based on the health controls was used as the positive value. The positive rate of KLK11 was compared among the three groups.ResultsThe positive rate of KLK11 in patients with ovarian cancer was significantly higher than those in patients with benign gynecologic processes or in healthy subjects[(73.3％) and(7.7％ ) or(6.3％ ) ,all P ＜0.01 )] ,and there was no significant difference between ovarian benign tumor group and the healthy control group ( P ＞ 0.05 ).ConclusionThe serum KLK11 should be a novel tumor marker in the clinical diagnosis of ovarian cancer.

Objective To investigate the MRI appearances of postpartum posterior reversible encephalopathy syndrome (PRES). Methods The clinical and radiological data of 8 patients with postpartum PRES were analyzed retrospectively, 5 cases were 1 week after postpartum,2 cases were 2 weeks afterpostpartum, 1 case was 4 weeks after postpartum. All cases underwent MRI examination, checking sequence included T,WI,T2WI,FLAIR,DWI,SWI, and 4 of them underwent MR venography (MRV). Results MRI showed basal bilaterally symmetrical distributions of lesions, mainly located in subcortex and cortex of cerebral hemisphere and predominantly in the occipital lobe,the lesions appeared as hyperintensity on FLAIR and T2WI,isointensity or mildly hypointensity on T1WI,hyperintensity on DWI. MRI in 8 patients demonstrated multiple lesions located in bilateral parietal lobe (8 cases),bilateral occipital lobe (8 cases), bilateral frontal lobe ( 4 cases ), bilateral temporal lobe (6 cases ), bilateral tempura-occipital lobe ( 8 cases),splenium of corpus callosum(l case), bilateral basal ganglia (l case), bilateral oval center( 1 case), bilateral cerebellar hemisphere (1 case), left frontal lobe hemorrhage (l case). Five patients' follow-up scan showed decreased or disappeared abnormal signals. Conclusion MRI examination scan identify the location, quality and degree, meanwhile, analyze the pathological foundation of postpartum PRES, which conduces to guiding treatment and preventing complication.

Objective To analyse the effect of eszopiclone combined with sertraline on serum S100βand clinical efficacy in patients with depression after cerebral infarction.Methods 58 patients who were diagnosed with depression after cerebral infarction were collected.All patients were randomly divided into experimental group and control group,29 cases in each group.Patients in the control group received sertraline treatment, patients in the experimental group were given eszopiclone treatment on the basis of control group, after the treatment, the serum levels of S100β,BDNF and clinical efficacy were detected in all patients.Results After treatment, compared with control group, the serum level of S100βwas lower in the experimental group(P<0.05); the serum level of BDNF was higher in the experimental group(P<0.05); the total efficiency was higher in the experimental group (P<0.05).Conclusion The eszopiclone combined with sertraline can significantly reduce the serum level of S100β,and improve serum level of BDNF in patients with depression after cerebral infarction,improve the therapeutic effect.

Helicobacter pylori (H.pylori) infection is the most important pathogenic microorganisms associated with the development of chronic gastritis, peptic ulcer and gastric mucosa-associated lymphoid tissue lymphoma (MALT) in children. H.pylori infection may occur in early childhood and last a lifetime even directly affecting the health of adulthood unlessH.pylori infection was eradicated. This article aims to review the infection condition, infection pathway and immunological characteristics ofH.pylori and its relationship with extragastroduodenal diseases in children.
