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 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.

Objective To investigate the relationship among age,menopausal status,serum 25 (OH)VD and skeletal metabolism index as PTH (Parathyroid Hormone),CA(Calcium),P (Phosphorus) and boned mineral density (BMD) of climacteric female in Xi'an.Methods 352 cases of healthy women at the age of 40～60 were collected who did routine examination in outpatient building of the First Affiliated Hospital of Xi'an Jiaotong University from January 2016 to April 2016.According to the results of skeletal density test,all subjects were divided into 3 groups as the normal group (T＞-1),the reduction group (-2.5＜T＜-1),the osteoporosis group (T＜-2.5).Electrochemiluminescent immunoassay (ECLIA) was used to detect levels of serum 25 (OH)VD,PTH,CA and P.Kruskal-Wallis test and chi-square test were used to analyze differences of age,serum 25(OH)VD,PTH,CA and P in different levels of bone mineral density groups.Results Compared with bone density normal group 2.24(2.18～2.29)mmol/L,serum CA levels of bone mineral density reduction group 2.27 (2.20 ～ 2.32)mmol/L and osteoporosis group 2.27(2.23～2.33)mmol/L were significantly higher (Z=9.669,P＜0.01).Serum P levels of bone mineral density reduction group 1.15 (1.09～ 1.23)mmol/L and osteoporosis group 1.18 (1.09～ 1.25)mmol/L were obviously higher than bone density normal group,1.11 (0.99 ～ 1.23) mmol/L (Z =13.64,P＜ 0.01).Ages of osteoporosis group 54(50～57) years and bone mineral density reduction group 51 (47～ 54) years were significantly older than Bone density normal group 47(43～50) years (Z=73.08,P＜0.01).The rate of menopause in osteoporosis group and bone mineral density reduction group were significantly higher than in bone density normal group (x2 =13.81,P＜ 0.01).There was no statistical difference in serum 25(OH)VD and PTH between groups.Conclusion This study found boned density of climacteric women is more likely correlated with age,menopause status and levels of serum CA and P.There was not enough evidence to prove that 25 (OH)VD and PTH have effect on skeletal density.Therefore,to monitor and detect the menopause status and levels of serum CA and P of climacteric female is critical for the prevention and treatment on osteoporosis of women.
