Objectives To study the serum level and the clinical significance of anti-ribosomal protein P0 antibody in discoid lupus erythematosus(DLE) and systemic lupus erythematosus(SLE) patients. Methods Serum anti-RPLP0 IgG antibody of 18 DLE patients and 23 SLE patients were tested by Enzyme-Linked Immunosorbent Assay (ELISA). Direct immunofluoreseence (DIF) was used to examined the immunoreaetants from skin lesion. Serum antibody and complement C3 were detected by conventional methods. Results Anti-ribosomal P0 antibody was higher in SLE patients (1.23 ± 0.62. mean ± SD) than in patients with DLE (0.53 ± 0.18, P<0.001) and healthy controls (0.72 ± 0.16, P<0.001), but was no difference in the later two groups (P=0.5). Among SLE patients , anti-ribosomal P0 protein antibody were much higher in patients with arthritis , nephritis and specific skin lesion than in those without these disorders (P<0.05). Anti-ribosomal P0 antibody was not associated with SLEDAI and CLASI(P=0.012). Conclusions There is no difference of serum anti-ribosomal P0 antibodies between healthy controls and DLE patients. SLE patients have higher level of serum anti-ribosomal P0 antibody , specially in those with specific skin lesion.

This article reviews the concept, importance, and assessment tools of nurse leadership. This article introduces the characteristics of each assessment tool and its application in different cultural backgrounds, so as to provide a reference for nurses to choose appropriate assessment tools, and to provide a basis for the development of assessment tools for nurse leadership in China.

Objective:To assess the validity and reliability of the Chinese version of the eleven-item Kutcher Adolescent Depression Scale (KADS-11)in Chinese adolescents,calculate its optimal cut-off value and the sensi-tivity and specificity,and explore the possibility of providing a useful tool to assess the severity of adolescent de-pressive symptoms.Methods:Totally 3180 students aged 11 -17 years were selected from schools in 6 provinces and Shanghai.All of them were asked to complete the KADS-11 and Children Depression Inventory (CDI). Students whose CDI scores were above 19 (including 19)were diagnosed with the DSM-IV criteria of depressive disorder,73 students from Shanghai sample were assessed with KADS-11 and CDI to analyze the test-retest reliabil-ity 1 month later.Results:Exploratory factor analysis showed that KADS-11 had 2 factors,and confirmatory factor analysis tested proved the 2-factor model fit better than the one-factor model.The KADS-11 total scores were posi-tively correlated with CDI total scores (r =0.74,P <0.01 ),and the KADS-11 scores were higher in depressive group than those in non-depressive group.The mean area under the curve (AUC)of KADS-11was 0.94,the mean area under the curve of each item ranged from 0.7 to 0.9.The optimal cut-off point of KADS-11 was total score≥9,sensitivity and specificity were 89% and 90% respectively.The Cronbach's alpha coefficient of the KADS-11 was 0.84,the spilt-half reliability coefficient was 0.71 (P <0.01),and the test-retest coefficient was 0.77 (P <0.01).Conclusion:The KADS-11 is appropriate for Chinese adolescents because of its good validity,reliability and diagnosis accuracy,it could be used to assess depressive symptoms for adolescents.

We produced beta1 gene which is about 2400 bp by reverse transcription polymerase chain reaction (RT-PCR) from bovine trachea, reclaimed and purified, then cloned the amplified fragment to pGEM-T easy vector, confirmed by sequencing. The immune-dominant epitope of beta1 gene was chosen by computer analysis and then syncretized ligand-binding domain from 346 bp to 843 bp of ecytoplasm with six histidine, expressed LBD protein massly in E. coli BL21 (DE3), and identified by SDS-PAGE. The fusion protein was purified with Ni-NTA affinity chromatography and immunized New Zealand rabbits preparing of its polyclonal antibody, the specific antibody titer was above 1:12,800 detected by indirect ELISA, the result of Western blot showed that this antibody could be recognized by LBD fusion protein.
