Objective To investigate perceptions of patient safety culture(PSC) among nurses in tertiary hospitals in Kunming. Methods Totally 2629 nurses were recruited by convenience sampling method from 7 tertiary hospi-tals in Kunming between July 2015 to January 2016. Hospital Survey on Patient Safety Culture (HSOPS) was used to assess PSC. Results The top three superior dimensions of PSC were Organizational Learning-Continuous Im-provement(86.60%),Teamwork within Hospital Units(83.34%) and Feedback and Communication about Error(75.98%). The last three inferior dimensions of PSC wereNonpunitive response to error(23.74%),Staffing(33.71%) and Teamwork across hospital units(49.45%). There were significant differences in certain items among nurses with different educational level,academic title,working hour per week(P<0.05). Conclusion Establishing nonpunitive re-sponse culture,reasonably arranging staffing and working hours,and encouraging nurses with high educational level and title to play their full role,are critical measures to improve patient safety culture in hospital.

Objective To explore the main factors affecting medical expenses of patients with colorectal cancer(CRC)and reduce such expenses by optimizing the clinical pathway of CRC according to the influencing factors.Methods Data of 467 discharged and medical insured CRC patients at Shanghai Cancer Center,Fudan University,were collected from 2009 to 2010.A multiple linear regression model was applied to analyze the influencing factors of medical expenses.The clinical pathway of CRC was optimized,and medical expenses before and after optimization were compared.Results Our data found days of stay and complications had impact on the medical expenses.Also,medical expenses were decreased accordingly with optimization of clinical pathway of CRC.Conclusion This study provides evidence for decision-making on single disease payment and medical insurance compensation on CRC.It is also meaningful to reduce the economic burden of patients with CRC.

Codon usage bias is an important characteristic of genetic information transfer in organisms. Analysis of codon usage bias of different species is important for understanding the rules on genetic information transfer. The previous method for analysis of codon usage bias is mainly based on genomic data. However, this method is greatly limited, because the genome sequences of higher organisms are still not available up to now. In this study, we found that we could obtain the same optimal codons of Ganoderma lucidum (Curtis: Fr.) P. Karst based on its whole genomic data or large-scale transcriptomic data from its liquid-cultured hyphae, primordium and fruiting body, separately. This result indicated the feasibility to understand the codon usage bias based on the large-scale transcriptomic data. By calculating the proportion of rare codons of Escherichia coli and Saccharomyces cerevisiae in 26 terpene synthases (TS) of G. lucidum, we found that the rare codons of S. cerevisiae have a higher proportion in TS genes, while the rare codons of E. coli have relatively lower, suggesting that the TS genes of G. lucidum are possibly more difficult to be expressed in S. cerevisiae than in E. coli. Chemical synthesis of TS genes according to the yeast optimal codons will be an effective way to solve the problem on the mismatch of gene codon bias between the foreign genes and the host strain.

N-acetyl-L-cysteine (NAC) capped quantum dots (QDs) were synthesized by a hydrothermal method and coated with 2-amino-2-deoxy-D-glucose (DG), polyethylene glycol (PEG), and 9-D-arginine (9R). The optical properties, morphology and structure of 9R/DG-coated CdTe QDs were characterized by ultraviolet-visible spectrometry, fluorescence spectrum, Fourier transform infrared (FTIR), proton nuclear magnetic resonance (1H NMR), liquid chromatography-mass spectrometer (LC-MS), sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and transmission electron micrographs (TEM). Furthermore, the biocompatibility, tumor targeted ability and transmembrane action of 9R/DG-coated CdTe QDs were studied. Results indicated that 9R/DG-coated CdTe QDs was constructed successfully by ligand exchange. The 9R/DG-coated CdTe QDs with the size of 8-10 nm had good dispersity and the absorbance and fluorescence peaks of CdTe QDs after modification were red shifted from 480 nm to 510 nm and 627 nm to 659 nm, respectively. In addition, the CdTe QDs modified by PEG, DG and 9R displayed good biocompatibility, high targeted ability to the cancer cells with glucose transporter type 1 (GLUT1) receptor high expression and obvious transmembrane ability.

OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).
METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.
RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).
CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.
