Objective To investigate the satisfaction degree of family members of children patients with the quality of nursing by follow-up analysis using telephone.Methods We used the high quality nursing questionnaire as the follow-up investigation.311 parents of the discharged pediatric patients were enrolled in this study,and answered the questionnaire within 1 ~2 weeks after their children were discharged from hospital.Meanwhile,we collected specific comments through asking questions by telephone.Then we analyzed and summarized the results by the content analysis.Results We found the total satisfaction rate was 96.65% and there were three levels after qualitative analysis on the specific recommendations:evaluation of the hospital system,evaluation of professional knowledge and skills of the medical workers,evaluation of the attitude of the medical workers.Conclusions The parents of pediatric patients are satisfied with the high quality nursing which has pediatric features.However,what the parents focused on had already beyond the scope of the high quality nursing itself.We should expand the concept of quality service to every aspect of the hospital work,in order to meet the needs of the parents of pediatric patients in the department of pediatrics.

Anxiety and depression are common conditions among patients with irritable bowel syndrome(IBS)which may induce or aggravate intestinal symptoms. Psychological factors are considered to be involved in the pathogenesis of IBS via both central and peripheral pathways,and functional magnetic resonance imaging(fMRI)revealed that several brain areas,such as anterior cingulate cortex and prefrontal cortex,are associated with IBS,anxiety and depression. This article reviewed the use of fMRI for studying the correlation of IBS brain activity with anxiety and depression and its role in the central pathogenesis of IBS.

Objective To assess the treatment of splenic artery aneurysms(SAA) and curative effect evaluation.Methods Twelve SAA patients treated in our hospital from January 2012 to May 2014 were clinical analyzed.The male in Twelve patients was 4 man and others were female.The vagus splenic artery aneurysms are originated from the superior mesenteric artery,tumors are single,from 1.5cm to 2.8cm in diameter,an average of 2.1cm.Twelve cases were performed surgery,4 patients underwent elective surgery,interventional embolization of the splenic aneurysm in 3 patient,The others were performed interventional embolization + superior mesenteric artery covered stents.Results Technical success was achieved in all twelve patients,2 patients had adverse effects such as abdominal pain,fever,etc.There revealed no aneurysm recurrence was found.Twelve patients were followed for 6-24 months,the follow-up by examinations with electronic computer X-ray tomography or color Doppler ultrasonic as well as angiography every 3 months.One patient died of severe abdominal bleeding 1 year later after the operation and the other eleven patients remained in good condition with no occurrence of re-canalization of the lesions.Conclusions For the vagus splenic aneurysm with suitable for anatornic conditions,cavity therapy is safe and effective,for the vagus splenic aneurysm involving hepatic artery,need to open surgery for vascular remodeling.

AIM: To investigate whether efficient production of neuron-like cells from embryonic stem cells(ESCs) can be indued by astrocyte-conditioned medium(ACM) in vitro.METHODS: Based on the 4-/4+ protocol established by Bain,two groups were studied: ATRA group,ATRA with ACM group.ESCs were induced into neuron-like cells by means of three-step differentiation in vitro.The totipotency of ESCs was identified by the observation of cells' morphology and the formations of teratoma in immunocomprised mice.The cell differentiation was evaluated continuously by detection of the cellular specific markers of neural stem cell, neurons and astrocytes such as nestin,NF-200,NSE and GFAP using immuno-histochemistry assay.RESULTS:(1) The ESC-D3 cells kept the ability of differentiation into cellular derivations of all three primary germ layers after continuous passage culture.(2) The ratio of NF-200 and NSE positive cells in the cells induced by ATRA with ACM was higher than that in the cells induced by ATRA only.(3) Finally,the positive rate of the neuron-like cells was up to 73.5% in the group induced by ATRA with ACM.CONCLUSION: The ESCs are induced into neuron-like cells with high purity and efficiency by ATRA with ACM.

Objective To explore the effects of murinecytomegalovirus(MCMV)infected mouse embryonic fibroblasts(MEF)on the proliferation and activation of regulatory T cell in vitro. Methods A co-culture system of T cell and MCMV infected MEF(T-MEF MCMV)was established.The viral load of supernatant was determined by plaque assay.The proliferation of T cells was observed with cell counting.The proportion of CD4+ CD25+ cells was measured by flow cytometry.The levels of Foxp3 protein were measured by Western blot.Reverse transcription polymerase chain reaction(RT-PCR)assay was utilized tO determine whether MCMV infection of MEF influenced the level of transforming growth factor(TGF)-β mRNA.The level of TGF-β protein in supernatant was measured by double-antibody sandwich enzyme linked immunosorbent assay(ELISA).The difference between T-MEF MCMV group and control group was assessed by one-way ANOVA.Results When T cells were co-cultured with MCMV infected MEF for 1 day and 3 days,the viral load in supernatant decreased.But when co-culture lasted for 6 days,the antiviral effect obviously diminished,as the viral load[(5.58±0.67)×105 PFU/mL]of the experimental group showed no statistic difference with MEF MCMV control group[(6.05±0.34)×105PFU/mL].When co-cultured with MCMV infected MEF for 3 days,T cell increased from pre-culture level of[(2.02±0.05)×106/mL]to(2.25± 0.13)×106/mL(P<0.05).But when co-culture lasted for 6 days,the number of T eelI returned to (2.08±0.14)×106/mL,which had no statistic difference with that of co-culture for 3 days system. Both the expressions of Foxp3 protein and the proportion of CD4+ CD25+ Foxp3+ Treg cells in T-MEF MCMV group were up-regulated as the infection time extended,which were two times and three times of the control group level,respectively.The mRNA level(A value)of TGF-β in MCMV infected MEF increased from baseline of 1.09±0.13 to 3.15±0.54 on day 3 after infection.The expression of TGF-β in supernatant 3 days after infection was(3.85±0.32) μg/L,which was significantly higher than that before infection[(1.74±0.14)μg/L,P<0.05].Conclusions Activated T cells have antiviral effect.However,the function of T cells is rapidly inhibited after activation,which may be due to the expression of Foxp3 mRNA induced by MCMV infected MEF and increased CD4+ CD25+ Treg proportion of the co-cultured T cells.TGF-β level is significantly increased after CMV infection,which may be an important mechanism of Treg proliferation.MCMV may manipulate Treg to evade specific immune elimination and,as a result,to cause CMV replication.
