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.

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.

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.

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.

Astemizole is nitrasoted with sodium nitrite in 0.12 mo l/L HAc solution at boiling bath for 25 min. The nitrosation product of astemizo le shows a reduction peak by single-sweep oscillopolarography. The peak potenti al is -0.72V (vs.Ag/AgCl). The first-order derivative peak current is propo rtional to the concentration of astemizole in the range of 4.0×10-7～1.6 ×10-5 mol/L (r=0.9997), with detection limit of 2.0×10-7 mol/L . The proposed method has been applied to the determination of astemizole in pha rmaceutical tablets.

OBJECTIVE:To develop a method for the determination of tirofiban in Tirofiban hydrochloride/sodium chloride injection.METHODS:Tirofiban was determined by UV spectrophotometry at a wavelength of 225 nm.RESULTS:The linear range of tirofiban was 30～70 ?g?mL-1(r=0.999 7) and its average recovery was 100.04% (RSD=0.23%).CONCLUSION:The method is simple,accurate and reliable for content determination of Tirofiban hydrochloride/sodium chloride injection.

Objective The objective of this study was to investigate the expression and clinical significance of transcription factors Sp1 and Survivin in breast cancer and to further analyze their correlation.Methods Seventy cases of breast cancer patients were diagnosed as breast cancer from June 2013 to June 2015.The expression of Sp1 and Survivin in 70 cases of breast cancer and 20 cases of adjacent normal tissues were detected by immunohistochemical staining.The relationship was detected between the protein expression and the clinicopathological parameters of breast cancer.Results The positive rates of Sp1 and Survivin in breast cancer were 71.43% and 78.57%,respectively.The positive rates of Sp1 and Survivin were 30% and 10% in adjacent normal breast tissues.They showed a significant difference(P<0.05).In breast cancer tissues,there were no differences in the lymph node metastasis,TNM stage and vessel infiltration(P>0.05).There were also no differences in the age,tumor size and histological grade of patients with breast cancer(P>0.05).In breast cancer tissues,there was a significant positive correlation between Sp1 and Survivin expression(r=0.517,P<0.01).Conclusion The transcription factors Sp1 and Survivin are closely related to the pathogenesis of breast cancer,which may serve as an adjunctive index for the diagnosis of breast cancer.It has certain guiding value for clinical diagnosis,treatment and prognosis of breast cancer.
