The construction of a medication safety culture is important for medication safety management and rational drug use.The construction of medication safety culture standards is formulated based on relevant national policies and regulations,accreditation standards for hospitals,expert opinions,the current situation,and the development trend of the healthcare industry.With scientificity,general applicability,instructive guidance,and practicality,they standardized basic requirements,management processes,and improvement of the construction of medication safety culture.To facilitate understanding and the implementation of the standards,we describe the process of standards formulation and explain the key points of the standards.

With the increasing life span of the population and the increasing proportion of the elderly population, the elderly with osteoporosis are prone to hip fractures, which brings heavy economic burdens to the family and society. The progress in predicting hip fractures from the aspects of the proximal femur geometry, bone mineral density (BMD), fracture risk assessment tool (FRAX) and finite element analysis (FEA) based on computed tomography (CT) imaging was reviewed, in order to understand the influencing factors of fracture risk, improve the accuracy of hip fracture risk prediction for the elderly, detect the high fracture risk group at an early stage, and hence to reduce the occurrence of fractures with appropriate preventing measures, and provide theoretical references for the prevention and treatment of hip fractures.

Objective: The present study was designed to evaluate the clinical significance of serum GP73 in patients with alcohol liver disease. Methods: Thirty-two patients with alcoholic liver disease (ALD), 40 patients with non-alcohol fatty liver disease(NFLAD), and 40 apparently healthy individuals were included in this study. Results: Compared with Those of healthy control population(43.91±19.02 ng/ml), the serum GP73 levels in ALD patients(93.39±66.91 ng/ml) were significantly increased, and also markedly higher than those of NFLAD patients (55.38±21.00 ng/ml). Taken the NFALD as"healthy controls" population, and ALD population as"patients" , the GP73 may be used to differentiate the ALD from NFLAD. The area of ROC analysis was 0.66(95%CI: 0.52~0.80, P=0.02). We set 75.65 ng/ml as the cut-off value for ALD diagnosis, the sensitivity and specificity were 50.0% and 85.0% respectively. Conclusion Serum GP73 levels in ALD patients were significantly higher than those of NFALD patients. GP73 may be a new marker for differentiating ALD from NFALD.

Currently,the toxicity study of traditional Chinese medicine is faced with the following problems. Firstly,the evaluation in vitro cannot fully reflect the true state of the body. Secondly,the traditional method is not sensitive enough to the early toxicity. Lastly,the toxicity evaluation indexes cannot determine whether the compatibility of traditional Chinese medicine produces toxicity or increases toxicity systematically. The paper proposed a synthesized early evaluation research method for target organ toxicity induced by traditional Chinese medicine:screening,validation,optimization and application. This method mainly inoolves early target organ toxicity biomarkers in screening,optimi?zation,validation,biological significance explanation,and application to the traditional Chinese medicine incompatibility based on the metabolic dynamic fingerprint spectrum in order to obtain biomarkers of target organ toxicity that are sensitive and precede conventional biochemical indices for early evaluation . We attempted to analyze the pattern of chang of the biomarkers for animals acted by″18 incompatible medicaments″compatibility combination. We found that Radix Aconiti Lateralis Preparata with cardiotoxicity were compatible with Rhizoma Pinelliae,and that Trichosanthes kirilowii Maxim,Fritillaria,Ampelopsis Radix and Bletilla striata without non-cardiotoxicity produced and increased cardiotoxicity systematically.

Background Corneal blindness is one of the major blinding eye diseases in China.With the development and progress of tissue engineering technology,tissue-engineered corneas offers a new approach to the treatment of corneal diseases.To select and cultivate ideal seed cells is a foundation of construction of tissueengineered corneas.Objective This study was to evaluate the efficiency of stripe off the Descemet membrane with endothelium plus enzymic digestion in the isolation of corneal endothelial cells and analyze the bionomics of rabbit corneal endothelial cells (CECs) in vitro.Methods Descemet membrane was stripped from fresh cornea of New Zealand rabbit under the dissection microscope.Descemet membrane with endothelium was incubated in trypsin and EDTA solution at 37 ℃ and then purified for CECs subculture in vitro.The morphology of the cultured cells was observed under the inverted microscope and marked by CM-Dil dye solution.Then the shape of the cells was observed by hematoxylin and eosin staining and the cells were identified for the expression of neuron specific enolase (NSE) using immunochemistry.The viability of the cells were evaluated by trypan blue staining.The surface structure of the cells were examined under the scanning electron microscope.Intercellular zonula occludens-1 (ZO-1) was identified by immunofluorecsence staining.Results A large number of purified CECs were obtained from Descemet membrane with endothelium through enzymic digestion.Cultured cells grew well and formed monolayer 5-7 days later with the cobblestone stone-like arrangement.The survival rate of the cells was 95％.CECs presented with the red annular fluorescence for CM-Dil with the labeling rate ＞90％.NSE was positively expressed in the cytoplasm.Polygon CECs were seen by hematoxylin and eosin staining and showed the brown staining.Abundant microvilli on the cellular surface and interconnected foot process were seen under the scanning electron microscope.ZO-1 showed the green fluorescence.Conclusions The method of striping off the corneal Descemet membrane with endothelium plus enzymic digestion can obtain abundant CECs.Cultured cells have good biological properties.This study may offer a feasible application in the engineering of corneal transplant membrane.

[ ABSTRACT] AIM:To evaluate the effects of 1α, 25-dihydroxyvitamin D3 on T helper cell 17 ( Th17 cells) and its related cytokines in a mouse model of corneal allograft transplantation.METHODS:C57BL/6 mice were transplanted with corneal grafts from BALB/c mice and treated intraperitoneally with 1.0μg 1α, 25-dihydroxyvitamin D3 or soybean oil every other day after operation.The transparency of the corneal grafts was evaluated for potential rejection signs by slit lamp biomicroscopy and histopathology.The expression levels of IL-17, RORγt and IFN-γin the spleen were measured by real-time PCR.Moreover, the protein expression of RORγt and IL-17 in the peripheral blood was analyzed by Western blotting. IL-17 and IFN-γin peripheral blood were measured by flow cytometry.RESULTS:1α, 25-dihydroxyvitamin D3 signifi-cantly inhibited the rejection of the corneal allograft and reduced the numbers of inflammatory infiltrates in the corneal graft. In the spleen, 1α, 25-dihydroxyvitamin D3 treatment reduced the expression levels of IL-17, RORγt and IFN-γ.In the pe-ripheral blood, 1α, 25-dihydroxyvitamin D3 treatment downregulated the expression levels of RORγt, IL-17 and IFN-γ. CONCLUSION:The effects of 1α, 25-dihydroxyvitamin D3 on suppressing corneal transplantation-induced allograft rejec-tion in mice are closely associated with its modulation on IL-17 and related cytokine RORγt.

Background Interleukin (IL)-1a-889C/T,IL-1β-S11C/T,+ 3962C/T and IL-1Ra-2 are different morphology of single nucleotide of interleuki-1 (IL-1).The potential relationship of IL-1 polymorphisms with Beh(c)et disease has been studied in several populations and groups.However,study outcomes are controversial for a long duration.Objective This Meta-analysis was to determine whether the IL-1 gene polymorphisms is associated with the pathogenesis and development of Beh(c)et disease.Methods The literature of the assoiation between IL-1 polymorphisms and Beh(c)et disease was retrieved from Medline,EMBASE,Cochrane Library,Web of knowledge,Google Scholar,Wanfang and CNKI databases.All the published original articles (case-control studies) were reviewed with the deadline May 31,2013,and the languages were limited to English and Chinese.Included reports were evaluated based on Newcastle-Ottawa Scale (NOS) score.The potential influence of IL-1α-889TT gene,IL-1β-3962C,IL-1β-511T and IL-1Ra-2 polymorphisms on Beh(c)et disease were analyzed.RevMan5.0,the Cochrane collaboration software program,was used to prepare and complete this review.The effect size was assessed using fixed effect model in the index with lower heterogeneity (I2 ＜50％) or randomized effect model in the index with higher heterogeneity (I2＞50％).Results The literature search resulted a total of 370 cases-controlled studies,and 7 studies met the included criteria,with the NOS scores ≥ 8.The total patients were 499 and normal controls were 708.Meta-analysis was performed on several populations.Overall,the polymorphisms of IL-1β-3962C allele increased the susciptibility of Beh(c)et disease (OR =1.41,95％ CI:1.06-1.88,P =0.02),and IL-1α-889TT genotype reduced the risk of Beh(c)et disease (OR =0.61,95 ％ CI:0.40-0.92,P =0.02).However,There was no significant association between variants of IL-1β-511T allele (OR =0.84,95％ CI:0.58-1.23,P=0.38) or IL-1RA-2 allele (OR =1.25,95％ CI:0.50-3.14,P=0.63) and Beh(c)et disease susciptibility.Conclusions These results suggest that Beh(c)et disease is associated with the IL-1 gene polymorphisms at the locations α-889C/T and β-3962C/T.A larger sample size clinical data still are need to confirm this conclusion.

Objective To study the relationship of soluble LAIR (sCD305 and CD3060) expression in recipient serum with cytomegalovirus (CMV) pneumonitis after renal transplantation. Methods Nineteen serum specimens from recipients were divided into CMV pneumonitis group (n=10) and control group (n=9). Then the concentrations of sCD305 and CD3060 were quantitated with sandwich ELISA. The data were analyzed by using student t test. Results sCD305 was skewness distributed in both 2 groups, was 0.000-3.039 μg/L in CMV pneumonitis group and 0.000-8.375 μg/L in con-trol group. CD3060 was skewness distributed in CMV pneumonitis group and the concentration was 0.000-0.017μg/L. CD3060 was mormally distributed in control group and the concentration was 0.046±0.035 μg/L. There was significant difference of CD3060 (P=0.000) concentrations and no sig-nificant difference of sCD305(P=0.316) concentrations in 2 groups, respectively. Conclusions The concentration of CD3060 is low in CMV pneumonitis patients. The combination of CMV PP65 antigen detection and CD3060 detection is helpful for the early and precise diagnosis of CMV pneumonitis in renal transplantation patients.
