Errors and flaws of clinical nursing practice can be fully exposed to voluntary reporting system of nursing errors, and then dramatically improving patient safety. This paper aims at exploring the theoretical basis, the characteristic of the system and essentiality for establishing voluntary reporting system of nursing errors, introducing the methods practicing both in abroad and in domestic, explaining its precondition and put forward a suggestion that the voluntary reporting system would be established in our own country.

Objective To assess the chest X-ray radiographic findings in children with influenza A (H1N1) virus infection. Methods The chest X-ray radiographies in 67 children with influenza A(H1N1) virus infection were reviewed in this study. The chest radiographies were obtained 3-8 days after the onset of symptoms and for the follow-up. Results The abnormalities were bilateral in 53 patients and unilateral in 7 patients. The predominant radiographic findings were bilateral patchy consolidation (n=42) with rapid confluence in 10 patients, lobular consolidation (n=7) with interstitial hyperplasia in 1 patient 3 month later, diffuse consolidation (n=11) with interstitial hyperplasia in all patients after 3 month. ConclusionThe predominant chest X-ray radiographic findings are bilateral patchy consolidation and diffuse consolidation with interstitial hyperplasia afterward.

In this paper, a detailed analysis was made on relevant literatures about bear bile powder in terms of chemical component, pharmacological effect and clinical efficacy, indicating bear bile powder's significant pharmacological effects and clinical application in treating various diseases. Due to the complex composition, bear bile powder is relatively toxic. Therefore, efforts shall be made to study bear bile powder's pharmacological effects, clinical application, chemical composition and toxic side-effects, with the aim to provide a scientific basis for widespread reasonable clinical application of bear bile powder.

Chronic prostatitis is a common male disease, and its pathogenesis is not yet clear. Most scholars believe that oxidative stress and immune imbalance are the keys to the occurrence and progression of chronic prostatitis. Currently immunotherapy of chronic prostatitis remains in the exploratory stage. This article relates the active ingredients of 5 Chinese medicinal herbs (total glucosides of paeony, tripterigium wilfordii polglycosidium, curcumin, geniposide, and quercetin) for the treatment of chronic prostatitis and their possible action mechanisms as follows: 1) inhibiting the immune response and activation and proliferation of T-cells, and adjusting the proportion of Th1/Th2 cells; 2) upregulating the expression of Treg and enhancing the patient's tolerability; 3) suppressing the activation of the NF-kB factor, reducing the release of iNOS, and further decreasing the release of NO, IL-2 and other inflammatory cytokines, which contribute to the suppression of the immune response; 4) inhibiting the production of such chemokines as MCP-1 and MIP-1α in order to reduce their induction of inflammatory response. Studies on the immune mechanisms of Chinese medicinal herbs in the treatment of chronic prostatitis are clinically valuable for the development of new drugs for this disease.

Objective: To analyze the expression of HLA class Ⅰ molecules and MHC classⅠ related chain A and B (MICA/MICB) in human nasopharyngeal carcinoma cell line (CNE2) and multi-drug resistant nasopharyngeal carcinoma cell line (CNE2/ DDP), and to assess their influence on NK cell-mediated lysis.Methods: Expression of HLA classⅠ molecules and MICA/MICB on the surface of CNE2 and CNE2/DDP cell lines was analyzed by flow cytometry. Cytotoxicity of NK cells (isolated from 3 healthy persons) against CNE2 and CNE2/DDP cells were detected by LDH releasing assay at different effect-to-target cell ratios (E∶T). In blocking experiments, anti-MHC class Ⅰ monoclonal antibody (mAb) (W6/32, a pan anti-HLA class Ⅰ antibody) and anti-MHC class I chain related molecules mAb (BAMO-1, specificly against MICA and MICB) were added to the target cells at a E∶T ratio of 10∶1. Results:It was found that the expression of HLA class Ⅰ molecules and MICA/MICB on CNE2 was higher than that on CNE2/DDP(P
