Objective To investigate the expression of aquaporin-4 (AQP4) in contused brain and contralateral side and correlation of AQP4 level with brain edema.Methods A total of 70 health adult SD rats were divided into sham operation group (n =10) and brain contusion group (n =60) according to the random number table.Except for no impact in sham operation group,the remaining operations were the same in both groups.Ten rats in brain contusion group were separately sacrificed at 1,6,24,48 and 72 hours,and 7 days.Pathological changes in brain tissues of rats were detected and immunohistochemistry staining and Western-blot were used to measure AQP-4 expression.Results There were no abnormalities of brain tissue structure in sham operation group with AQP4 expressed mainly in glial cells and vascular endothelial cells.With respect to the injured side in brain contusion group,mixed brain edema that consisted of angioedema and cellular edema occurred along with tissue necrosis,massive inflammatory cell infiltration,and microgial proliferation.AQP4 was apparently expressed in gliocytes and vascular endothelial cells,which showed a fall at 1 hour,the lowest at 6 hours,the peak at 24 hours,slow fall at 48 hours,a second peak at 72 hours,and then a fall until 7 days.Level of AQP4 other than that at 1 hour had significant difference compared with sham operation group (P ＜ 0.01).Whereas the contralateral side in brain contusion group showed no pathological abnormalities at 1 hour,but cellular edema emerged at 6 hours followed by mixed brain edema mainly characterized as cellular edema at 24 hours,continued cellular edema but alleviated angioedema at 48 and 72 hours,and alleviated cellular edema at day 7.AQP4 was up-regulated in gliocytes and vascular endothelial cells,which decreased at 1 hour (1.313 ± 0.01),minimized at 6 hours (0.922 ± 0.03),peaked at 24 hours (2.848 ± 0.020),fell at 48 hours,peaked again at 72 hours (2.662 ± 0.02) and fell to almost normal level at day 7.By contrast with sham operation group,level of AQP4 had significant difference other than that at 1 hour and 7 days (P ＜ 0.01).Conclusions After brain contusion,angioedema and subsequent cellular edema emerge in the contused side.Pathological changes are delayed in non-contused side with cellular edema ahead of angioedema.Level of AQP4 is closely related with traumatic brain edema.

Hepatitis C virus (HCV), one of the major pathogens of viral hepatitis, causes significant hazards in humans. Interferon treatment in combination with ribavirin is used as the first line clinical treatment for HCV infection. However, good response to this treatment has only been observed in few patients and repeated recurrence has also been reported frequently. Therefore, new antiviral agents and therapies are in urgent demand. Here, we report a newly constructed Escherichia coli RNase P based M1GS ribozyme that can specifically and efficiently target the core gene of HCV. The guide sequence (GS) of this M1IGS was designed according to the sequence of the core coding region of HCV genome. The GS was then covalently linked to the 3' terminus of M1 RNA, the catalytic subunit of RNase P from Escherichia coli. The specification of this sequence-specific ribozyme, M1GS, was then examined using an in vitro cleavage assay. The cytotoxicity and its activity in inhibition of HCV gene expression and viral proliferation were further studied in vivo. Our results show that the reconstructed M1GS ribozyme displayed obvious catalytic activity in cleaving target mRNAs fragment in vitro. Notable reduction in the expression of HCV core protein and a 1 000-fold reduction in viral growth were also observed in cultured HCV infected Huh7.5.1 cells expressing the functional M1GS ribozyme. This study demonstrated a direct evidence for the antiviral activity of the customized M1GS-HCV/C141 ribozyme, and thus provided a promising new strategy for clinical treatment of HCV infection.

Objective To analyze the incidence of complications during and after interventional therapy for common con-genital heart disease (CHD) in children. Methods From January 2011 to December 2013, interventional therapy of common congenital heart disease which include ventricular septal defect (VSD), atrial septal defect (ASD), patent ductus arteriosus (PDA) and pulmonary valve stenosis (PS) were performed in 2356 patients. Among them, 159 patients who developed complications during and post to interventional therapy were retrospectively analyzed. Results The overall complication rate was 6.75%(159/2356) (11.40% post VSD occlusion, 7.50% post ASD occlusion, 3.09% post PDA occlusion, 1.63% post percutaneous balloon pulmonary valvuloplasty (PBPV) ).The rate of arrhythmia was 4.41%(102/2356). The severe complication rate was 2.71%(64/2356) (3.62%post VSD occlusion, 2.21%post ASD occlusion, 2.53%post PDA occlusion, 1.63%post PBPV). The intraoperative severe complication rate was 0.51%(12/2356);the early severe complication rate was 1.99%(47/2356);the late severe complication rate was 0.21%(5/2356). Interventional therapy rate was 0.13%(3/2356); cardiovascular surgery rate was 0.64%(15/2356);conservative treatment rate was 1.95%(46/2356). The mortality rate was 0.08%(2/2356). Conclusions The complications and mortality rate of interventional therapy for CHD in children are relatively low, but cannot be ignored. The complication could be reduced by choosing proper indications, following the operational procedures and careful operative follow-up.

Objective To investigate the level and influencing factors of subjective well-being of nurses and establish a model of the relationship of job stress, self-efficacy and subjective well-being. Methods Totally 438 nurses from 5 hospitals in Changchun city were investigated with the self-designed demographic questionnaire, General Well-Being Scale, Nurse Job Stressors Scale and Self-Efficacy Scale. Results The total score of subjective well-being was (71.36 ± 18.83) points. Single factor analysis found that age (F=1.759, P<0.01), department (F=1.712, P<0.01), professional title (F=1.364, P<0.05), years of working (F=1.420, P<0.05) and monthly income (F=1.632, P<0.01) were statistically significant. Multiple linear regression analysis showed that sex (t=-2.447, P<0.05), the first factor of job stress (t=-5.033, P<0.01), the second factor (t=-2.478, P<0.05), the third factor (t=-2.315, P<0.05), the fifth factor (t=-5.862, P<0.01) and self-efficacy (t=10.705, P<0.01) were the predictive effectton of subjective well-being. The result of path analysis shows that self-efficacy has a significant effect of adjustment on job stress and subjective well-being (direct effects=-0.62, indirect effects=-0.24, P<0.01). Conclusions The nurse subjective well-being is in the medium level. Hospitals and all related departments should take effective measures to reduce or eliminate unfavorable factors and increase the protective factors, and then improve the level of nurses′subjective well-being and nursing quality.
