Objective:To explore the multiple meditation effects of hope and coping style between social sup-port and life satisfaction. Methods:Totally 381 left-behind children (191 boys,190 girls;234 from primary school, 147 from junior middle school)aged 10-15 years were selected. They were assessed with the Social Support Rat-ing Scale (SRSS),Children's Hope Scale (CHS),Simplified Coping Style Questionnaire (SCSQ)and Satisfaction with Life Scale (SWLS ). The relationship among these factors was analyzed by structural equation modeling. Results:The total scores of SRSS,CHS and SWLS were positively correlated with the scores of positive coping style(r=0. 28 -0. 43,P<0. 01 )and negatively correlated with the scores of negative coping style(r=-0. 19--0. 14,P<0. 01). Path analysis showed that social support had indirect effects on life satisfaction of left-behind children through the mediation of hope,positive coping and negative coping style(RMSEA=0. 03,GFI=0. 99,NNFI=0. 98). Bootstrap test showed that 95% confidence interval of mediation effects was 0. 002-0. 348, and the multiple meditational effects were significant. Conclusion:It suggests that hope,positive coping and nega-tive coping style might play a multiple mediation effects on the relationship between social support and life satisfac-tion.

Cell-based therapy and regenerative medicine offer a paradigm shift in regard to various diseases causing tissue or organ damage.Recently,many authors have focused their atte(n)tion on adipose-derived mesenchymal stem cells (ADMSCs) for their capacity to differentiate into many cell lineages.Acute kidney injury (AKI),as a common emergency,has high morbidity rate and relatively limited treatment.This review will summarize the mechanism of ADMSCs in treatment of acute kidney injury,and hope to lay a foundation for future research.

The paper introduces the research significance of Traditional Chinese Medicine ( TCM) literature information retrieval based on cognition analysis, by analyzing cognition of literature information demands of TCM students in different majors of Liaoning University of Traditional Chinese Medicine, it studies from three perspectives:literature information retrieval demand, retrieval thinking and development direction of TCM literature information retrieval system.It also points out that study on thinking and practice of literature information retriev-al based on cognition analysis is the effective approach to enhance information literacy and improve the comprehensive quality.

On the basis of reviewing the significance of retrieval teaching and scientific research integration and the research situation at home and abroad,the paper proposes the undergraduate teaching optimization plan of literature information retrieval of Traditional Chinese Medicine (TCM) teaching integrated with scientific research,points out that the teaching design should focus on the cultivation of scientific research ability,the teaching process advocates the efficient and rich communication form based on the students,and the course assessment should establish multi-dimensional evaluation system.

Ischemia reperfusion injury (IRI) is a multistep pathophysiological process involving a complex of multi-factors.To alleviate the IRI is of great importance in clinical liver transplantation,especially for marginal donor livers.This article overviewed the protective strategies and the latest progress for alleviation of IRI in three stages of liver transplantation,which includes liver procurement,preservation and reperfusion.

Rheumatoid arthritis(RA),a systemic,inflammatory autoimmune disorder characterized by inflammation of the lining or synovium of the joints,is a complex polygenic disease with a complicated inheritance mode.Both genetic and environmental factors determine the development and progression of RA.Study on susceptible genes of RA provides a theoretic basis for clinical diagnosis and treatment.As a novel high-throughput screening method,genome-wide association study(GWAS) is a powerful approach for mapping susceptible genes of polygenic disease like RA.GWAS can not only verify the well-established susceptible loci,but also identify novel genetic loci candidates.Great improvement has been made in using GWAS to screen for novel genes,which casts new lights on the mechanism and treatment of RA.This review summarizes the progress in using GWAS for screening of RA susceptible genes.

Objective To evaluate the early outcome of off-pump total arterial revascularization using bilateral IMA with "Y" manner. Methods Between Oct.2002 to Aug.2004, 52 patients underwent off-pump coronary artery bypass grafting (OPCABG) using bi-IMA. The mean age was 56 (33-78) years. Triple vessel disease was in 42 (80%) patients. The free right IMA was anastomosed to the in-sitr left IMA, composed “Y” graft. LIMA anastomosed sequentially to the diagonal branch and LAD and RIMA were sequentially to the ramus, obtuse marginal and PDA. Results There was no 30-day death. 171 grafts were constructed and the mean number of grafts per patient was 3.3. Peri-operation MI occurred in 2 patients, temporary IABP in one. There were no sternal wound infection and strode. Conclusion Off-pump total arterial revascularization using bilateral IMA with "Y" manner is secure and feasible.

Objective To describe the epidemiology and clinical characteristics of spinal infections to assist the clinical diagnosis and treatment .Methods Clinical data of all cases with spinal infections at He′nan Provincial People′s Hospital from January 2010 to December 2014 were analyzed retrospectively . The demographic characteristics , risk factors , clinical characteristics and outcomes were evaluated . Variables were compared by t‐test ,chi‐square test or Fisher exact test when appropriate .Results Totally 231 patients fulfilled the inclusion criteria and were reviewed ,of which 179 (77 .5% ) were pyogenic spinal infection (PSI) and 52 (22 .5% ) were tuberculous spinal infection (TSI) .The most common risk factor for infection was history of previous spinal surgery or procedure (43 .3% ) ,followed by diabetes mellitus (14 .7% ) .The infection site of lumbosacral spine was prominent with 114 cases (63 .7% ) in PSI and 38 cases (73 .1% ) in TSI .At initial presentation ,white cell blood count ([10 .8 ± 4 .5] × 109/L vs [7 .3 ± 3 .2]× 109/L ,t=2 .685) and C‐reactive protein levels ([79 ± 33] vs [37 ± 21] mg/L ,t=6 .241) in PSI were higher compared to TSI (both P<0 .05) .The positive rate of blood culture was significant higher than tissue culture in PSI (47 .9% vs 21 .8% ,χ2 = 6 .782 , P< 0 .05 ) .But the positive rate of blood culture was significantly lower than tissue culture in TSI (0 vs 39 .4% ,χ2 =8 .312 , P<0 .05) .Surgical treatment was performed in 30 .2% of PSI and 25 .0% of TSI .Conclusions History of spinal surgery or procedure is the most common risk factor for spinal infections , followed by diabetes mellitus . The lumbosacral spine is the common involved site in both PSI and TSI .The incidence of PSI is higher among spinal infections in our hospital .And Staphylococcus aureus is the most common pathogenic bacteria in PSI .

Objective To evaluate the short -term efficacy and adverse reactions of gemcitabin combined with nedaplatin to patients with metastatic triple -negative breast cancer after taxane and/or anthracycline treatment. Methods Thirty -three patients with anthracycline and/or taxane -resistant metastatic triple -negative breast cancer received gemcitabin and nedaplatin regimen:gemcitabin 1 000 mg/m2,d1,8 days,intravenous;nedaplatin 80mg/m2,d1,intravenous.Treatments were repeated every 21 days and response rate was evaluated every two cycles. Results Of 33 patients, complete remission ( CR) in 1 case ( 3.03%), partial remission ( PR) in 13 cases (39.39%),stable disease(SD) in 11 cases(33.33%),progressive disease(PD) in 8 cases(24.24%),objective response rate was 42.42%.The main adverse reaction was bone marrow suppression and gastrointestinal reaction. Conclusion Combination therapy of gemcitabin and nedaplatin is an effective and well tolerated rescue regimen in anthracycline and/or taxane -resistant metastatic triple -negative breast cancer patients.

Drug delivery system targeting immune system plays an important role in the treatment of inflammatory diseases.Drug delivery system targeting immune system could target immune cells or immune organs.It could be divided into active targeting mediated by the interaction of ligand-receptor or antigen-antibody and passive targe-ting mediated by pH;particles and so on.This review summarizes new progress for drug delivery system targeting immune system;which provides a theoretical reference for designing the safe and effective drug delivery system and providing efficient and safe treatment for inflammatory diseases.
