Objective We tried to investigate the current status of pediatric nursing post setting and analyze the practical application effect in the clinical working practice for the foundation of readjusting and setting up the pediatric nursing positions.Methods By convenient sampling method,the general condition and current post setting situation in the pediatric wards of 7 hospitals with self-designed questionnaires were investigated.The results underwent analysis Results The nursing post setting in pediatric wards of 7 hospitals were not all the same,nursing posts in the pediatric ward included three categories:management positions,teaching positions and clinical positions.Management positions included the head nurse,deputy head nurse and head nurse assistant; teaching positions included the teaching secretary and clinical total teaching nurse; the seven kinds of clinical nursing positions were office job,day shift,night shift,evening shift,midnight shift,late-morning shift,auxiliary job.Though some nursing jobs differed in the position names and working hours,their job contents were nearly identical.Conclusions Pediatric nursing post setting management in our country is still in the exploratory stage at present,it has not form a unified perfect job management system.Pediatric nursing positions should be set from the perspective of evidencebased theory,satisfying the demands of patients as the guidance,coming from clinical needs as the first principle,in the full implementation of the accountability for nursing and based on comprehensive consideration of various factors,so that the post setting can be scientific and reasonable.

Objective To investigate the associations of IL-6(rs6949149,rs1800796 and rs10499563) and IL-6R(rs2228145) single nucleotide polymorphisms(SNP) with the risk of gastric cancer in Chinese Han population of Xuyi,Huai'an.Methods A total of 400 patients with gastric cancer and 400 healthy controls were enrolled in this case-control study.The genotypes of the four SNPs were detected by the Mass-Array technology.The associations between the IL-5/IL-6R SNPs and the risk of gastric cancer were analyzed by Logistic regression model.Results There was a significant difference in the distribution of the IL-6 rs1800796 genotypes between the patients with gastric cancer and healthy controls(x2 =6.213,P =0.045).The IL-6 rs1800796 GG genotype was associated with a increased risk of gastric cancer(adjusted OR =1.27,95 ％ CI:1.15-3.20,x2 =6.326,P =0.012).Subgroup analysis showed that the associations between the IL-6 rs1800796 GG genotype and the risk of gastric cancer were obvious in the female(adjusted OR =3.99,95％ CI:1.36-11.71,x2 =6.358,P =0.012) and the patients with H.pylori infection(adjusted OR =2.20,95％ CI:1.08-4.45,x2 =4.770,P =0.029).Conclusion The IL-6 rs1800796 GG geuotype is associated with the risk of gastric cancer,especially in the female and the patients with H.pylori infection.

Objective To compare the clinical effects between electrical stimulation and acupuncture for dysphagia in acute stroke,and provide effective option for the patients with post-stroke bulbar palsy.Methods A total of 80 patients (40 post-stroke true bulbar paralysis patients and 40 post-stroke pseudo bulbar paralysis patients)were randomly divided into true bulbar paralysis-electrical stimulation group(group A1),true bulbar paralysis-acupuncture group(group A2),pseudo bulbar paralysis-electrical stim-ulation group(group B1),pseudo bulbar paralysis-acupuncture group(group B2).These patients were treated with electrical stimu-lation or acupuncture combined with rehabilitation training for 2 weeks.Results In group A1,4 cases were better effective,12 cases were effective,and 4 cases were no effective.In group A2,2 cases were better effective,7 cases were effective,and 1 1 cases were no effective.The response rate was 80%(1 6/20)in group A1 and 45%(9/20)in group A2.There was statistically significant difference (P =0.022).In group B1,6 cases were better effective,12 cases were effective,and 2 cases were no effective.In group B2,5 cases were better effective,12 cases were effective,and 3 cases were no effective.The response rate was 90%(18/20)in group B1 and 85%(1 7/20)in group B2.There was no statistically significant difference(P =0.633 ).Conclusion Electrical stimulation or acu-puncture combined with early rehabilitation training could provide good effect for post-stroke pseudo bulbar paralysis patients.For post-stroke true bulbar paralysis patients,it was better to choose electrical stimulation combined with early rehabilitation training.

Objective To observe the correlation between nuclear factor ?B(NF-?B) expression and apoptosis after hypoxia-ischemia brain damage(HIBD).Methods Forty-eight 7-day newborn Sprague-Dawley(SD) rats were randomly divided into 2 groups: control group (n=24) and HI group (n=24).The expression of NF-?B in the hippocampus was detected by immunohistochemical techniques.The apoptosis of the hippocampal cells was detected by terminal deoxynucleotidyltransferase-mediated 2-deoxyuridine 5′-triphosphate-biotin nick end labeling(TUNEL)straining.Results The expression of NF-?B in hippocampal cells increased at 6 h after HIBD,peaked at 48 h,and lasted till 72 h when compared with control group(Pa

The research of interleukin-13 receptor ?2(IL-13R?2) chain is a rising pop these years.Previous studies have shown that many human tumors overexpress IL-13R?2 chain,while normal cells do not express this receptor or express very low level.This difference of express level is significant to diagnose and cure tumors by the IL-13R?2-directed toxin fusion protein.During the past decade,the structure and the function of IL-13R?2 together with the relationship between this receptor and tumors has been further developed.Therefore new therapies and theories can be proposed as the clinical tumor treatments.In this case,the expression in various tumor cell lines was not only focused on but also on the IL-13 and toxin fusion protein killing effect in both the cell level and the in vivo level.Besides,an overview of the mechanism in the treatment of IL-13R?2-directed toxin fusion protein together with the improved methods for fusion protein purification and other relative tumor therapy was given.In conclusion,the current status and progress of IL-13R?2 as well as IL-13R?2-directed toxin fusion protein in tumor therapy were represented.
