护理安全品管圈在血管外科护理中的应用效果

Objective: To study the effects of nursing safety quality control circle in the nursing in department of vascular surgery. Methods: Totally 230 patients in vascular surgery department from January 2015 to January 2016 were randomly divided into 2 groups. Assessment the risk factors of disease for each patient , 115 cases in the control group, the shift nurses nurse by traditional method; 115 cases in experimental group ,who were given quality control circle to improve the nursing quality., and the adverse event and compliance,satisfaction to nurses of the patients were compared. Results: The incidence of adverse events and complications (6%) in the experimental group were lower than those in the control group (15.5%). The patients' satisfaction with nurses' job (97.4%) was higher than that of the control group (87%). Conclusion: The implementation of nursing safety quality control circle activities in vascular surgery nursing, effectively reduce the incidence of adverse events and complications during hospitalization, improve the quality of nursing and help patients recover soon.目的  探讨护理安全品管圈在血管外科护理中的应用效果。方法  随机选取2015年1月—2016年1月在本科住院患者230例并随机将其分为两组，对每位患者进行疾病危险因素评估，对照组115例，各交接班护士采用传统护理方法；实验组115例，对患者实施护理安全品管圈活动提高护理质量，比较两组的不良事件和并发症的发生率、患者对护士工作的满意度、患者住院天数。结果  实验组不良事件和并发症的发生率（6%）均低于对照组（15.5%）；患者对护士工作的满意度（97.4%）高于对照组（87%），住院天数较对照组也大大缩短。结论  在血管外科护理中实施护理安全品管圈活动，有效的降低了患者住院期间不良事件和并发症的发生率，提高了护理质量，有助于患者早日康复

Diaqua­bis(1,10-phenanthroline)magnesium dichromate(VI) 1,10-phenanthroline disolvate

In the title compound, [Mg(C12H8N2)2(H2O)2][Cr2O7]·2C12H8N2, the cation and anion are situated on a twofold rotation axis. The MgII ion is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from coordinated water mol­ecules in a distorted octa­hedral geometry. Inter­molecular O—H⋯N and O—H⋯O hydrogen bonds and π–π inter­actions between the aromatic rings [shortest centroid–centroid separation = 3.527 (2) Å] link the cations, anions and 1,10-phenanthroline solvent mol­ecules into a hydrogen-bonded cluster

Photooxidation Contribution Study on the Decomposition of Azo Dyes in Aqueous Solutions by VUV-Based AOPs

The effects of pH value, VUV intensity, initial dye concentration, initial H2O2 concentration, and TiO2 loading dose on the degradation of three azo dyes: acid Orange 8, acid Blue 29, and acid Blue 113 were studied to explore and compare the treatment efficiencies among the adopted AOPs. It was found that pH played an important role in the degradation of dyes using VUV irradiation. For VUV/H2O2, VUV/TiO2, and VUV/TiO2/H2O2 processes, the decoloration rates of the three azo dyes were more efficient under acidic conditions relative to alkaline conditions. The degradation rates of dyes increased with increasing concentrations of H2O2, but reaction rates were retarded at high concentrations of H2O2 because the H2O2 compound acted as a scavenger of the hydroxyl radical. In this paper, three azo dyes were decomposed efficiently by VUV irradiation only demonstrating the effectiveness of VUV direct photolysis

(S)-Ethyl 1,2,3,9-tetra­hydro­pyrrolo[2,1-b]quinazoline-1-carboxyl­ate

The title chiral compound, C14H16N2O2, was prepared by esterification of (S)-1,2,3,9-tetra­hydro­pyrrolo[2,1-b]quinazol­in-1-carboxylic acid in the presence of HCl/EtOH. In the mol­ecule, the quinazoline ring is non-planar and exhibits a distorted half-chair conformation, while the five-membered ring shows a typical envelope conformation. Inter­molecular C—H⋯N hydrogen bonding helps to stabilize the crystal structure

Ectopic Six3 expression in the dragon eye goldfish

For goldfish (Carassius auratus), there are many varieties with different eye phenotypes due to artificial selection and adaptive evolution. Dragon eye is a variant eye characterized by a large-size eyeball protruding out of the socket similar to the eye of dragon in Chinese legends. In this study, anatomical structure of the goldfish dragon eye was compared with that of the common eye, and a stretching of the retina was observed in the enlarged dragon eye. Moreover, the homeobox-containing transcription factor Six3 cDNAs were cloned from the two types of goldfish, and the expression patterns were analyzed in both normal eye and dragon eye goldfish. No amino acid sequence differences were observed between the two deduced peptides, and the expression pattern of Six3 protein in dragon eye is quite similar to common eye during embryogenesis, but from 2 days after hatching, ectopic Six3 expression began to occur in the dragon eye, especially in the outer nuclear layer cells. With eye development, more predominant Six3 distribution was detected in the outer nuclear layer cells of dragon eye than that of normal eye, and fewer cell-layers in outer nuclear layer were observed in dragon eye retina than in normal eye retina. The highlight of this study is that higher Six3 expression occurs in dragon eye goldfish than in normal eye goldfish during retinal development of larvae. (C) 2007 Elsevier Inc.
