Objective To study the application effect of PDCA management mode in the teaching process of practice nurses in spine surgery to reduce the occurrence of nursing errors. Methods A total of 35 practice nurses in spine surgery from March 2014 to March 2015 received the routine teaching mode were set as control group, and 35 practice nurses from April 2015 to April 2016 implemented PDCA management mode were set as intervention group. The occurrence rate of nursing adverse events in two years was observed, and the interns for clinical teaching evaluation model of quality and satisfaction and the intern examination results were summarized. Results The incidence of nursing adverse events was 22.86% (8/35) in control group, and 2.86% (1/35) in intervention group, the difference was statistically significant (χ2= 17.85, P = 0.00). The intern teacher for clinical teaching content arrangement, teaching attitude, detail guidance and skills training indicators evaluation score were (15.46±1.03), (14.18±1.06), (14.61±1.11), (13.30±1.07) points in control group, and (18.26±1.00), (18.48±0.51), (19.43±0.21), (19.16± 0.28) points in intervention group, the differences were statistically significant (t = 11.54- 31.34, P <0.01). The interns given theory and skills examination results were (80.15±1.61), (85.16±1.02) points in control group, and (93.10±2.01), (91.06±2.03) points in intervention group, the difference was statistically significant (t = 29.75, 15.36, all P = 0.00). The clinical teaching satisfaction was 57.14% (20/35) in control group, and 80.00% (28/35) in intervention group, the difference was statistically significant (χ2=12.12, P=0.00). Conclusions PDCA management model applied to clinical practice in department of orthopedics teaching process, can effectively improve the intern theory knowledge and skills to master the ability, most of the interns examination results are more optimistic, and for this kind of management pattern for the process of teaching evaluation of higher satisfaction, the teachers care under the guidance of intern nursing mistake, nursing adverse events is low, this method is worthy of promotion.

Objective:To prepare monoclonal antibodies with high specificity against different regions of N protein and to analyze antigenic epitopes of SARS-CoV N protein.Methods: Balb/ c mice were immunized with purified different region N protein to prepare McAb by hybridoma technique and select by indirect ELISA.Both of these McAbs were characterized for their antibody titre in the culture supernatant as well as ascites,class,subclass and affinity analysis.The antigen specificity for McAb were evaluated and confirmed by Western blot.The binding site and capability of McAb were observed by ELISA additive assay.Results: Seven hybridoma cell lines secreting monoclonal antibodies against SARS-CoV N1 and two hybridoma cell lines secreting monoclonal antibodies against SARS-CoV N2 were obtained.About the immunoglobulin subclass of McAb,six were IgG1,two were IgG2b and one was IgG3.Western blot showed that the McAbs reacted specifically with SARS-CoV N protein.ELISA additive assay indicated that two antibodies against SARS-CoV N1 recognized same epitopes,while others recognized distinct epitopes.Conclusion: We successfully obtained nine specific McAbs against the different region SARS-CoV N protein after expression and purification of the different part SARS-CoV N protein.It shows that the N1 McAb recognizs the N-terminus of the N protein whereas the N2 McAb recognizs the C-terminus.

Objective To observe the effect of sinomenine on the proliferation of fibroblast-like synoviocytes (FLS) and expression level of MMP-3 secreted by FLS in rheumatoid arthritis in vitro. Methods FLS were obtained by digesting synovial tissues with collagens and were divided into four groups:sinomenine high, middle, low concentration and control group. The proliferation of FLS was assessed by methyl- thiazolyl-tetrazolium (MTT) assay and the mRNA expression of MMP-3 was measured by semi-quantitative RT-PCR respectively after treated by sinomenine. Results The rate of FLS proliferation was significantly reduced in groups treated by sinomenine. Compared with control group, the mRNA expression of MMP-3 markly decreased in sinomenine groups (P

Coats disease is a relatively rare and idiopathic disorder characterized by retinal telangiectasia and massive intra-retinal and (or) sub-retinal lipid accumulation, resulting in complications including retinal detachment and neovascular glaucoma. Previous reports have revealed that Coats disease can be associated with other disorders, especially some inherited diseases, such as retinitis pigmentosa (RP) and facioscapulohumeral muscular dystrophy (FSHD). Coats disease associated with other inherited disorders is generally called Coats-like retinopathy, which has some unique features that differs from the classic Coats disease, for example there is no sex and age preference, more bilateral cases, more severe cases and more genetic factors involved. Patients of Coats-like retinopathy with RP and FSHD may have mutations in Crumbs homologue gene 1 and D4Z4 genes.

ObjectiveTo study the effect community health education on the quality of life in chronic obstructive pulmonary disease (COPD) patients.Methods Three hundred and sixty patients with COPD in remission were set as the observation group, while another 212 COPD patients during the same period as the control group.The control group received conventional health education and the obseravation group received systematic,targeted health mode.The two groups were compared in respect of the quality of life.Results Before intervention,the two groups showed no significant differences in the total score on quality of life as well as its dimensions (P>0.05).After intervention,the study group was higher than the control group in the total score on quality of life as well as its dimensions (P<0.05).Conclusion The community health education is effective for improving the quality of life of COPD patients.

Objective] To explore the clinical experience of Professor Zhang Juan on Elderly Diabetic Constipation and hope to provide a new perspective for future study about Chinese medicine treatment of Diabetes Mellitus(DM).[Method] Reviewed 103 cases from Sep. 2014 till now who were older than 65,diagnosed with DM and had constipation as primary symptom. Analyzed and summarized the syndrome differentiation and treatment of the cases. [Results] According to the etiology and pathogenesis of Elderly Diabetic Constipation ,Professor Zhang deems that its pathogenesis takes place in two stages:one is spleen deficiency,the other is kidney deficiency and proposes the therapy of“treat the middle-jiao if others are not working”,“nourish the natal qi with post-natal qi”,“combine disease,syndrome and symptom”and“treat in stages”.[Conclusion] The treatment on Elderly Diabetic Constipation raised by Professor Zhang is effective and her clinical experience has important clinical value .

Atherosclerosis is a multifactorial disease and mediated by chronic inflammation from initiation to progression. Inflammatory factors of this process, such as C-reactive protein, interleukin-6, cell adhesion molecules and tumor necrosis factor-a, not only involve in atherosclerosis-related disease process, but also indicate the risk of cardiovascular events. Inflammatory factors level plays a significant role in diagnosis, treatment and prognosis of atherosclerosis-related disease, such as acute coronary syndrome. Recent studies have shown that there is a marked inflammatory response after stenting, which plays an important role in the vascular remodeling process, especially in-stent restenosis. Therefore, it is necessary to explore the molecular mechanism and pathological changes in the process of inflammation and to study prevention and treatment of the inflammation. We believe that inflammatory processes will be new targets of therapy in preventing or treating atherosclerosis and its complications.
