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 investigate clinicopathologic characteristics of obsolete Bennett fractures and their surgical treatment and prognosis. Methods From August 2008 to April 2010,13 patients with obsolete Bennett fracture were admitted to our department.They were 12 men and one woman,with an average age of 34.3 years (from 17 to 42 years).They had a fracture history of over 4 weeks to as long as 12 weeks (average,7.9 weeks).In all patients,after X-ray examinations,the radio-dorsal ligament complex of the first carpometacarpal joint was properly released,fracture gaps were cleared up,fracture fragments were anatomically reduced and fixed with a Kirschner wire,and at last the first metacarpal joint was fixed with the Kirschner wire crossing the joint Postoperatively all patients were immobilized with cast plaster for 4 weeks before the Kirschner wires acrross the joint were removed.Gradual rehabilitation was conducted.The X-rays were taken every month. Results The patients were followed for 6 to 24 months(average,14 months).The fractures healed in all the patients,with an average healing time of 3 months.No dislocation of the joints occurred.Injury to articular cartilage of the trapezium bone occurred in one patient,and no apparent pain was experienced in the other 12 patients.According to the Total Active Motion assessment,the thumb function was rated as excellent in 9 cases,good in 2,moderate in one and poor in one,with a good to excellent rate of 84.6％.Conclusions In obsolete Bennett fractures,the radio-dorsal ligament complex of the first carpometacarpal joint will have cicatricial contracture,preventing reduction of the fragments of the radio-dorsal joint.Therefore it is important to properly release the radio-dorsal ligament complex to achieve anatomical reduction of the radio-dorsal joint.An injury history of over 3 months and complicated injury to the trapezium bone cartilage may be significant factors affecting the prognosis of obsolete Bennett factures.

Objective: To clone the 5＇-flanking region of the human CD34 gene containing transcriptional regulatory sequence (TRS). Methods: According to the registered 5＇-flanking region of CD34 gene, two pairs of primers were designed and net-PCR was used to amplify 661 bp long TRS of CD34 gene. The CD34 TRS fragment was cloned into reported plasmid pEGFP-1. The role of the regulating the specific expression of recombinant plasmid pCD34 EGFP in hematopoietic and non-hematopoietic cells was observed. Results: Restrictive endonuclease identification and DNA sequencing provedthat the CD34 promoter cloned was consistent with the sequence reported to a large extent. It could induce the EGFP gene to express in hematopoietic cell line K562 specifically, while has no effect on hepatocellular carcinoma cell HepG-2. Conclusion: The cloned CD34 gene TRS has the effect of regulating gene expression specifically. The study established the fundament for the construction of specific gene expression vector used in hematopoietic system cells.

The optic nerve disease is a kind of diseases that seriously affect the visual function. In recent years, magnetic resonance diffusion tensor imaging ( DTI ) technology has been widely applied in the field of optic nerve diseases. Compared with the ophthalmic testing, such as optical coherence tomography imaging, visual evoked potential, field of vision, this method has obvious advantages. It not only can directly show the morphology changes of the optic nerve, visual pathway and visual cortex, but also can quantitatively analyze the morphological and pathological changes of the optic nerve, visual pathway and the visual cortex. This article reviews the imaging principle of diffusion tensor imaging, the progress and development prospect of diffusion tensor imaging in the study of the optic nerve diseases.

Biotechnology supremacy is a newly-advanced power theory. It is a superior dominance of military biotechnological application based on the microcosm of life structure within a certain period of time. The advancement of biotechnology supremacy and modern biotechnology has created the concept of bio-micro-frontier, which involves information and defense resources of all living ultra-micro-organisms with national and regional characteristics. Being feasible both in theory and practice, the implementation of bio-micro-frontier system is strategically important. This article explores the implementation of bio-micro-frontier in terms of strategy and tactics, which will add a unique dimension to future military transformation and active defense.
