1.Leukemia inhibitory factor and central nervous system diseases
International Journal of Pediatrics 2012;39(5):507-509
Leukemia inhibitory factor(LIF) is a multifunctional cytokine.In recent years,investigations have made some advancement in the effect of LIF on central nervous system.LIF shows a high expression in various central nervous system diseases and related animal models,which shows a neuroprotective effect most time in central nervous system injuries.LIF is defined as a neurotrophic factor.It might provide a new strategy for the therapy of central nervous system diseases to undertake further studies on leukemia inhibitory factor and central nervous system diseases.

AIM: To study the expression of endostatin in ischemic myocardium of myocardial infarction(MI) rats in various periods and the correlation with VEGF expression and microvascular density(MVD).METHODS: Thirty-two male Sprague-Dawley rats after myocardial infarction were randomly divided into 7,14,21 and 28 days group.The sham group was normal control group(eight rats in each group).The expression of endostatin,VEGF and MVD in ischemic myocardium were observed by immunohistochemistry.RESULTS: The expression of endostatin significantly increased in the ischemic myocardium after MI,peaked at 7 days,then gradually decreased at 14,21 and 28 days.The endostatin level at 28 days was the same as the shams.The changing trends of expression of endostatin in ischemic myocardium after MI were similar to that of VEGF and were significantly correlated with the MVD.CONCLUSION: The expression of endostatin increased in ischemic myocardium of myocardial infarction rats.The changing trends of endostatin were similar to that of VEGF and positively correlated with the MVD.These data suggest that endostatin may modulate ischemic myocardium angiogenesis after myocardial infarction.

Objective To discuss the feasibility of developing psychological pressure assessment tools coping with hospitalized patients based on Neuman systems model. Methods We analyzed the fea-sibility of developing assessing tools specifically by theoretical analysis, literature review and case study.Results It was proved that Neuman systems model was suitable for guiding the development and applica-tion of assessment tools for evaluating the psychological pressure. Conclusions Neuman Systems Model could effectively evaluate the psychological pressure of non-psychiatric settings. Therefore, it can be con-cluded that the model is suitable for developing the psychological assessment tools for hospitalized patients.

Since the release rate of protein in hydrogels is directly dependent upon the size of the protein and the hydrogel, how to deliver low molecular weight protein for prolonged periods has always been a problem. In this article, we present a usage of self-assembling peptide (P3) with the RGD epitope on its N terminus. The concentration of the released insulin-like growth factor 1 (IGF-1) was determined by UV-vis spectroscopy and the release kinetics suggested a notable reduction of the IGF-1 release rate. Cell entrapment experiments revealed that IGF-1 delivery by biotinylated nanofibers could promote the proliferation of the mouse chondrogenic ATDC5 cells when compared with cells embedded within nanofibers with untethered IGF-1.

Objective To explore the pressure of hospitalized patients and protrudent problem of mental stress.Methods Choosing 150 non-psychiatric patients in random for investigation using mental status scale in non-psychiatric patients.At last, data were analyzed to find out the stressors they were bear-ing in hospital.Results There existed mental pressures in hospitalized patients in some degree."to ex-pect to recover health early" was the highest score (7.21±3.17), and "to worry about their position de-creased after disease" got the lowest score, (2.56±2.15).The mental stress of hospitalized patients was cor-related with age, sex, education degree, income and marital status.Conclusions There existed mental pressures in hospitalized patients in some degree.Different mental stressor shows different psychological re-action, we should take different measures to improve the life and nursing quality of hospitalized patients.

Objective We sought to evaluate the effect of structured health education on quality of life and the end point of patients with coronary disease with evidence-based method.Methods The Cochrane Library,Cochrane Database of Systematic Reviews (CDSR),Medline (OVID),Pubmed and Web of Science were searched to collect the randomized controlled trials (RCT) which mentioned the structured health education to CHD patients,the quality of the RCTs was evaluated by Jadad Score,then effective data were extracted and analyzed by Meta-analysis with RevMan 5.2 software.Results A total of 12 eligible studies of RCT were included in the study with Jadad Score evaluations at B level or above.There were 20 476 cases in the intervention group,14 522 cases in the control group.Meta-analysis showed that the quality of life scores of the intervention group were significantly higher than those of the control group,weighted mean difference was 3.29,95% CI (0.49-6.09).No significant difference was found in cardiac morbidity outcomes,re-hospitalization and the mortality rate,relative risk,95% confidence interval were respectively 0.72(0.50-1.04),0.98(0.86-1.11),0.77(0.58-1.03).Conclusions The structured health education can improve the quality of life of patients with coronary disease,but has no obvious effect on the cardiac morbidity outcomes,re-hospitalization and mortality rate.We suggest transitional care to be carried out in future research to decrease the incidence rates of them.

Objective To investigate training of the ultrasound-guided modified Seldinger technique(MST)for cannulation of PICC.Method Twenty-nine nurses trained with the traditional training on ultrasound-guided MST during December 2009 to December 2011 were set as control group and another 29 nurses trained with the systematic training during December 2011 to December 2013 were as experiment group.The training effect were compared between the two groups after 2 months training.Results The theoretical knowledge in the experiment group was improved significantly compared with the control group. Moreover, the success rate of catheterization in the experiment group was 100.0%,significantly higher than that in the control group(both P<0.01).Conclusion Systematic training system is more effective than the traditional training.It can improve the nurses’technical and theoretical knowledge on ultrasound-guided MST for PICC.

Objectives To analyze comparatively the adverse reactions of Nedaplatin(NDP)and Cisplatin(DDP)in concurrent chemoradiotherapy for locally advanced nasopharyngeal carcinoma and summarize the nursing points as well.Methods From March 2012 to March 2013,112 patients with locally advanced nasopharyngeal carcinoma were randomly divided into NDP group and DDP group.Besides intensity modulated radiotherapy for both groups,NDP group were treated with intravenous drop infusion of NDP by 100 mg/m2 and the control group with intravenous drop infusion of DDP by 100 mg/m2 both for three courses of once every three weeks (e.g.day one,day 22 and day 43 during the course).The two groups were compared in terms of therapeutic effects and incidences of adverse reactions.Results The complete remission rates of the NDP group and DDP group were 87.5%and 85.7%,respectively (P>0.05).The incidences of adverse reactions like gastrointestinal reactions and radioactive mucositis in the NDP group were significantly lower than those in the DDP group(P<0.05)and the index of platelet decrease was significantly higher(P<0.05).There were no significant differences between the two groups in terms of liver and kidney dysfunction and white blood cells decrease(P>0.05). Conclusions Chemotherapy with NDP combined with radiotherapy for locally advanced nasopharyngeal carcinoma has fewer adverse effects and is easy to be accepted by patients so that their quality of life can be improved.In the application of the two kinds of chemotherapy,we should pay attention to the adverse reactions on patients in order to give pertinent care.
