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.

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.

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.

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.

Objective To investigate dynamic changes of plasma D-dimer, C-reactive protein (CRP) and fasting plas?ma glucose (FBG) levels in elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) combined with type 2 diabetes mellitus. Methods AECOPD group (n=65) was used as A group, AECOPD combined with type 2 diabetes mellitus group (n=65) was used as B group. Levels of D-dimer, CRP and FBG were observed and compared between two groups in the first day, the 3rd day, the 7th day and the 14th day after hospital admission. The correlation be?tween D-dimer, CRP and FBG was analyzed. Logistic regression analysis was used to estimate the factors affecting increased plasma levels of D-dimer. Results Levels of D-dimer, CRP and FBG were significantly higher in B group than those of A group in the first day, the 3rd day, the 7th after hospital admission (P<0.01). Values of D-dimer and CRP were declined ob?viously in A group in the 7th day after hospital admission, but in B group they were declined obviously until the 14th day. There was no significant difference in FBG of A group. The level of FBG was significantly decreased in B group. There was a positive correlation between D-dimer, CRP and FBG (P<0.05). Logistic regression analysis showed that CRP, FBG, p(O2) and age were the influence factors for the increased levels of D-dimer. Conclusion In elderly patients with AECOPD com?bined with type 2 diabetes mellitus, we should pay attention to anti-inflammatory and controlling blood sugar, and the dy?namic monitoring levels of D-dimer, which helps to improve the prognosis for patients with AECOPD, and reduce mortality.

Objective To investigate clinical features of microscopic colitis (MC) in the elderly and short-term effect of mesalamine on MC.Methods Totally 116 elderly patients with MC in our hospital were recruited from January 2011 to December 2011.Clinical manifestations,use of MC related drugs (MCRDs),pathological classifications and short-term effect of mesalazine were collected and analyzed.Results MC patients accounted for 27.6 ％ in elderly patients with chronic diarrhea,who presented with mild to middle watery or mucous stool,and only 1.7％ of MC patients accompanied with severe stomach pain.Collagenous colitis (CC) and lymphocytic enteritis (LC) accounted for 31.9％ and 68.1％,respectively in MC patients and 50％ of them had MCRDs taking history.There was a significant difference in short-term effective rate between CC group and LC group at 4 weeks after mesalazine treatment (64.9％ vs.84.8％,x2 =5.929,P=0.015).The effective rate was significantly related with the relief of pathology in LC group (x2 =5.896,P=0.015).The relapse rate had no significant difference between CC group and LC group at 8 weeks after withdrawal of mesalazine treatment (45.8％ vs.34.3 ％,P =0.317).Conclusions MC may be one of the main reasons leading to chronic diarrhea in the elderly.Mesalazine has a better effect for the short-term treatment of MC in the elderly,but the long-term maintenance therapy still needs further study.
