Objective To establish the questionnaire of nursing assistant requirements of county hospital, test and analyze its reliability and validity. Methods According to the nursing assistant requirements framework had been constructed, document literature and interview to develop a questionnaire item pool, then established the prequestionnaire after research group discussion and expert evaluation. 250 clinical nurses were selected for investigation. Then item analysis,factor analysis, correlation analysis and reliability analysis were applied to test the scale′s validity and reliability. Results The effective questionnaire was 224 copies. Questionnaire of nursing assistant requirements was consisted of 44 items, the factor analysis of the questionnaire identified six principal factors and explained for 53.225% total variances. Correlation coefficient between each dimension and the total scale was 0.532-0.794, the Cronbach α coefficient of each dimension was 0.789-0.910,the Cronbach α of whole scale and split- half coefficient were 0.923 and 0.868. Conclusions The questionnaire of nursing assistant requirements of county hospital has high reliability and validity.It can provide a scientific basis for county hospital to carry out nursing assistance.

Objective To build the county level hospital nursing assistance need indicator system in Jiangxi province.Methods Literature review,qualitative research method and Delphi expert consultation method were adopted to build the county level hospital nursing assistance need indicator system.The indicator system was revised through trial test.Results Two rounds of expert consultation showed that expert authority degree coefficients were 0.79,0.83; Coordination coefficient(Kendall's W) was 0.11～0.16; content experts consistency coefficient was 0.78,reliability Cronbach's α coefficient was 0.85.Through expert advice and pre-examinaion,the county level hospital nursing assistance need indicator system was built,consisting of 3 level Ⅰ indicators,8 level Ⅱ indicators,43 level ⅠⅡ indicators,including assistance contents,assistance ways and assistance time.Conclusions This study established the county level hospital nursing assistance need indicator system with better scientific and feasible characteristics.It can provide experience and guidance for the relevance and effectiveness of the implementation of follow-up care aid work.

Objective To investigate and analyze the nursing assistance requirements and the influencing factors of county hospital of Nanchang city.Methods A total of 327 nurses in 6 country-level hospital of Nanchang city were surveyed by the self-made questionnaire.Results The total demand score of county hospital was (4.29±0.47) scores,which was in a high level.The helping content demand was the highest,the form of assistance needs was the lowest.From the specific items of view,prevention of incision infection,nursing training,critically ill patients with bedsore nursing were higher in the content of assistance.Send a nurse to support education,nursing training,hospital experts on-site guidance were higher in the form of assistance.Long term assistance for 1 years,short-term assistance for 4-6 months were the highest in demand of helping times.The main factors of influencing county hospital nursing assistance were work area,department,degree,title etc.The work area was the important influencing factor of nursing assistance of county hospital.Conclusion The relevant departments are recommended to develop personalized assistance scheme according to the recipient hospital needs.

OBJECTIVE: To explore role of Nods (nucleotide-binding oligomerization domain Nod Like receptors) kind of pattern recognition receptors (PRR) in patients with allergic rhinitis. METHOD: The mRNA and protein of Nod1, Nod2 of Nalp3 were analyzed in the turbinate mucosa of patients with allergic rhinitis, nasal septum deviation (NSD) nasal mucosa of patients and nasal polyp mucosa with Real-Time RT-PCR, Western blot and immunohistochemistry respectively, and Nod1 expression changes was explored in PBMC with wad explored Western-blot and then the level of IL-4, IL-6, IL-10, IFN-γ were detected in serum of AR after desensitization treatment. RESULT: These Nods like receptors, mainly found in nasal mucosa epithelial cells, glandular epithelium and inflammatory cells (e. g. plasma cells, eosinophils), were expressed in the nasal mucosa tissues. In AR group, Nod1 (mRNA and protein) expression were lower than NSD group (P<0.05), Nalp3 expression were higher than (P<0.05), while, there was no significant difference of Nod2 (mRNA and protein) between groups. After 6 months desensitization therapy, the change of Nod1 in PBMC was negatively correlated with the change of IL-10 in the peripheral blood, r=-0.88, P<0.05; while, change of Nod1 was positively correlated, with the change of IL-6, r=0.57, P>0.05. CONCLUSION Nod1, Nod2 and Nalp3 expression were seen in the two groups,and the Nod1 expression in allergic rhinitis group was lower than other two groups, while, the Nalp3 was higher than other two groups. It showed Nod1, Nalp3 may be involved in the pathogenesis of allergic rhinitis. Expression of Nod1 in PBMC reduced after sublingual desensitization treatment. Besides, the change of Nod1 was negatively correlated with the change of IL-10 in PBMC. So,it seemed that Nod1 may regulate IL-10 changes and be involved in sublingual desensitization therapy.

OBJECTIVETo investigate the regulation of adipose-derived mesenchymal stem cells (ADSC) on helper T cells and regulatory T cells in allergic rhinitis(AR) mouse model and the underlying mechanisms.

METHODSUsing random number table, 60 Balb/c mice were divided into 6 groups (represented by: sensitized/challenged/treated ), they were the experimental group 1(OVA/OVA/high dose ADSC), the experimental group 2(OVA/OVA/low dose ADSC), the experimental group 3(OVA/OVA/PBS), the experimental group 4(OVA/OVA/0), the control group 1(PBS/PBS/0) and the control group 2(0/0/0). The mouse ADSC were isolated and cultured through conventional method, and AR mouse model was built with OVA and aluminum. The mice were injected with high (3×10(6)), low (1×10(6)) ADSC respectively labeled by CM-Dil for 3 consecutive days via tail-vein injection and sacrificed 48 hours later. Finally, levels of IL-4, IL-6, IL-10 and IFN -γ in serum were examined by ELISA; expressions of the four cytokines in spleen were examined by q RT-PCR; migration of ADSC to mouse model nasal mucosa were observed through fluorescence microscope; eosinophil infiltration were observed by the nasal HE staining.

RESULTSMouse ADSC was isolated, cultured and identified successfully. There was significant difference in symptom scores of AR models (compared with 0/0/0 group, P<0.01). The IL-4 and IL-6 levels of OVA/OVA/high ADSC group were significantly lower than OVA/OVA/0 group (group 1: (17.95±7.78), (27.51±5.93) pg/ml; group 4: (56.82±9.12), (70.03±7.22) pg/ml), the IFN-γ and IL-10 levels increased significantly (group 1: (367.74±13.79), (417.10±72.40) pg/ml; group 4: (199.46±11.25), (122.50±15.57) pg/ml) in serum. These differences were statistically significant(P<0.01). Compared with OVA/OVA/low ADSC group, the IL-4 and IL-6 levels decreased significantly (group 1: (17.95±7.78), (27.51±5.93) pg/ml; group 2: (41.57±12.27), (56.21±9.23)pg/ml) of OVA / OVA / high ADSC group, and the IFN-γ and IL-10 increased significantly (group 1: (367.74±13.79), (417.10±72.40)pg/ml; group 2: (281.77±30.41), (203.45±87.10) pg/ml). These differences were statistically significant(P<0.01). At the same time, the corresponding changes observed at the levels of the cytokines' mRNA. ADSC labeled by CM-Dil could migrate to the mouse nasal mucosa. OVA/OVA/high ADSC group showed the more red fluorescence than the OVA/OVA/low ADSC group. The eosinophils in nasal mucosa of the two groups reduced compared with the normal control.

CONCLUSIONADSC injected via tail-vein can migrate to nasal mucosa and play non-specific immune effects, that may to effect the releases of some cytokines then to regulate the Th1/Th2 imbalance and the function of Treg cell, finally that be dose-related in a certain extent.
