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.

Objective To explore the relation between the expression of breast cancer stem cells(BCSCs) related gene CD44 , OCT4 and Twist1 in breast cancer tissues and swelling axillary lymph nodes with the recurrence and metastasis of breast cancer . Methods The genes and antigen expressions of BCSCs relative factors CD44 ,CD24 ,OCT4 and Twist1 in th breast cancer tissue and axillary lymph nodes were detected by the immunohistochemical method and RT‐PCR .Results Totally 14 cases of preopera‐tively and intraoperatively diagnosed breast cancer had axillary lymph nodes metastasis of cancer cells .The over expression of BC‐SCs relative factors CD44 ,OCT4 and Twist1 antigen positive in the breast cancer tissue and axillary lymph nodes were detected by the immunohistochemical method ,while CD24 was lowly expressed;the gene expressions of BCSCs relative factors CD44 ,OCT4 and Twist1 in the breast cancer tissue and axillary lymph nodes were enhanced by the RT‐PCR detection (P<0 .05) ,while CD24 gene was lowly expressed(P>0 .05) .Conclusion The genes and antigen expression of BCSCs related factors CD44 ,OCT4 and Twist1 in the patients with breast cancer complicating swelling axillary lymph nodes are significantly increased ,which might indicate that the BCSCs related factors are related with easily early metastasis and recurrence of breast cancer cells .

Objective To investigate the optimal condition for transforming alkanna tinctoria pigment into shikonin. Methods Transformation rate of shikonin served as index. Transformation temperature, time, ratio of 2% NaOH to alkanna tinctoria pigment (v/w) was optimized. Results With ratio of 2% NaOH to alkanna tinctoria pigment being 4.5 mL·mg-1, temperature 35℃ and the reaction time 4 h, the transformation rate reached the highest, and the average transformation rate was 64.86%. Conclusion This method is easy and simple, and suitable for industrialized production.
