Objective To study the relationship among the sense of organizational fairness, innovative self-efficacy (ISE) and innovative behavior in nurses. Methods A total of 392 nurses from a grade A tertiary hospital were selected as the research subjects using convenience sampling method. The Organizational Fairness Scale, Innovation Self-efficacy Scale, and Innovation Behavior Scale were used to evaluate the sense of organizational fairness, ISE, and innovation behavior, respectively. The mediate equation model was constructed, and Bootstrap analysis was applied for validation. Results The scores for organizational fairness, ISE, and innovative behavior among the nurses were (67.8±15.2), (23.9±3.5), and (30.5±6.7) points, respectively. Organizational fairness score was positively correlated with both innovative behavior and ISE scores ［correlation coefficients (r) were 0.38 and 0.36, respectively, both P<0.01］. ISE score was positively correlated with innovative behavior total score (r=0.51, P<0.01). The results of the mediation analysis indicated that the total effect of organizational fairness on innovation behavior was 0.34 (P<0.01),with a direct effect of 0.17 (P<0.01). ISE plays a mediating role between organizational fairness and innovation behavior among nurses(P<0.01) with standardized mediation effect of 0.17, accounting for 50.0% of the total effect. Conclusion Organizational fairness can influence the ability of innovative behavior directly or through the mediating role of ISE.

Objective To construct recombinant adeno-associated virus and lentivirus carrying siRNA of TIMP-1 and to investigate the efficiency of infection and short-term inhibitory effect of TIMP-1 gene expres-sion on rat hepatic stellate cells. Methods One pair of siRNA which could effectively inhibit expression of the TIMP-1 gene in HSC-T6 was screened and cloned into AAV vector and lentiviral vector to construct the recombinant AAV/siRNA-TIMP-1/GFP and Lenti/siRNA-TIMP-1/GFP. AAV/GFP and Lenti/GFP as neg-ative control were also obtained. Experiments were assigned to five groups: AAV/siRNA-TIMP-1/GFP, AAV/GFP, Lenti/siRNA-TIMP-1/GFP, Lenti/GFP group and mock group. Rat HSC-T6 cells were infected by these recombinant viruses at a concentration of MOI by 10. To monitor the efficiency of infection, fluores-cence microscope and flow cytometer were used. After 7 d post-infection, Western blot was used to detect the TIMP-1 protein expression. Results HSC-T6 had no significant changes after infection. The efficiency of infection in AAV/GFP and Lenti/GFP group were 72.7% and 70.0%, AAV/siRNA-TIMP-1/GFP and Lenti/siRNA-TIMP-1/GFP group were 64.58% and 61.86%. The protein expression levels of TIMP-1 in HSC-T6 cells at 7 d post-infection by the recombinant AAV and Lentivirus were decreased 40.0% compared with those in mock control and normal HSC-T6 (P<0.05). Conclusion Recombinant AAV/siRNA-TIMP-1/GFP and Lenti/siRNA-TIMP-1/GFP could effectively infect HSC-T6 with similar efficiency and suppress the expression of TIMP-1 in rat HSC-T6 remarkably.

Objective To evaluate the prognostic value of combined examination of pre-operative carcinoembryonic antigen (CEA) and CD44v6 for colorectal cancer patients. Methods A total of 140 patients with complete clinical data pathologically diagnosed as colorectal cancer from December 2012 to December 2017 in Hainan Hospital of PLA General Hospital were enrolled. Finally, 69 validated cases excluding CEA (-) or CD44v6(-) patients were registered according to pre-operative CEA detection and immunohistochemistry results of CD44v6. Kaplan-Meier method was used to analyze the progression-free survival (PFS) time for single factors. Multiple-factor analysis was done by using Cox proportional hazard model. Results Sixty-nine patients included 29 cases of double positive and 40 cases of double negative in CEA and CD44v6. There were statistical significances of the expressions of double positive and double negative in patients with different gender, M stage, TNM stage. Double positive was more apparent in female (χ2 = 4.42, P= 0.04), presenting of metastasis (χ2=5.06, P=0.02) and advanced cases (χ2=4.38, P= 0.04); univariable analysis showed the N stage (P=0.00), M stage (P=0.00), TNM stage (P=0.00) and double positive/double negative in CEA and CD44v6 (P= 0.04) were likely to affect the PFS, however, multivariable analysis showed that N stage (HR= 0.15, 95 ％ CI: 0.03-0.86, P= 0.03), TNM stage (HR= 23.83, 95 ％ CI: 3.65-155.51, P=0.00) were the independent prognostic factors for PFS. PFS in double positive patients was shorter than that in double negative ones [24.0 months (3-84) vs. 31.0 months (8-94), P=0.04]. Conclusion Pre-operative combined examination of CEA and CD44v6 could be helpful in judging the prognosis for colorectal cancer patients.
