AIM: To explore the influence of CD47 molecules on the maturation and function of cultured dendritic cells (DCs). METHODS: Monocyte cell-derived DCs were propagated in granulocyte-macrophage colony-stimulating factor (GM-CSF) and lipopolysaccharide (LPS) plus interleukin (IL)-4, in the presence or absence of anti CD47 monoclonal antibodies (anti-CD47 mAbs). Flow cytometry was used to detect the cell surface phenotype. The concentration of IL-12P70 in supernatant was measured by ELISA technique. The antigen-presenting functions of DCs were determined in one-way mixed leukocyte reaction by Brdu-ELISA. Electrophoretic mobility shift assays (EMSA) was used to examine NF-?B activity. RESULTS: The anti-CD47 mAbs markedly suppressed the expression of CD80,CD86,CD83,CD1a,HLA-DR on the surface of DCs (P

Promotion of outstanding people to head nurses is key to hospital nursing management.In view of the current shortcomings in the analysis of appraisal data and the interpretation of appraisal results,the analysis of means(ANOM)method is introduced to the process of hospital human resource management.The proposed method aims to solve the problem when the score differences between interviewers are great and the score differences between candidates are small.An example for head nurses' promotion appraisal in a hospital is offered to demonstrate that statistical tools can provide the decision support for hospital personnel selection.Finally,the application differences between ANOM and analysis of variance(ANOVA) in human resources appraisal are compared.

Objective To explore the relationship between the change of serum ferritin level and acute lung injury.Methods 192 cases living hospital patients with critical factor of acute lung injury were divided into two groups:acute lung injury group(study group,52 cases)and having critical factor of acute lung injury but not devel- oped acute lung injury group(control group,140 cases).50 people at the same time were selected as normal group. Serum ferritin level were measured,and their correlation between groups were analyzed.Results The serum ferritin level in study group[female(354.7?9.8)/,g/L,male(789.7?30.8)tag/L]increased significantly as compared wit h that in control group[female(182.7?7.8)/,g/L,male(312.5?1.9)?g/L](P

Abstract: Objective　To explore the relationship between body mass index (BMI), waist-hip ratio (WHR) and the risk of gout in Urumqi. Methods　A total of 516 male patients with gout in a third-class hospital in Urumqi from 2015 to 2019 were randomly selected as the gout group and 516 male healthy subjects in the same hospital as the control group. The relevant blood biochemical indexes were examined and analyzed. Blood pressure, waist circumference and hip circumference were measured. Body mass index and waist-to-hip ratio were calculated. Logistic regression model was used to analyze the relationship between overweight / obesity, waist-to-hip ratio and the risk of gout. The test level is α = 0.05. Results　Uric acid, glucose, urea nitrogen, creatinine, triglyceride, low-density lipoprotein, systolic blood pressure, weight and waist circumference in gout group were higher than those in control group, and the differences were statistically significant (P<0.05); There were no significant differences in age, height and diastolic blood pressure between the two groups (P<0.05). There was a positive correlation between BMI and WHR and the occurrence of gout (r=0.272, 0.345, P<0.05). There were significant differences in BMI, WHR and waist circumference between the gout group and the control group（χ2= 55.338, 54.928, 54.153, P<0.05）. After adjusting for age, aerobic exercise and other confounding factors, the results of multi-factor unconditional Logistic regression analysis showed that the odds ratio (OR) of gout in patients with BMI of 24.00-27.99 kg/m2 and ≥28.00 kg/m2 was 2.005 (1.337-3.006) and 2.677 (1.668-4.296) times higher than that of patients with normal BMI, respectively. The OR value of gout in patients with WHR≥0.90 was 1.668 times higher than that in patients with normal WHR, and the difference was statistically significant. The results of subgroup analysis according to age are generally similar. Conclusions　The BMI and WHR of man with gout in Urumqi are higher than those of normal people, and BMI, waist circumference and WHR are all associated with the incidence of gout. The risk of gout increases with the increase of BMI and WHR.

Membrane proteins are the main undertakers of biofilm function, and also the most important target group for innovative drug discovery and research. About 60% of drugs targets are membrane proteins. Due to the obvious aggregation and denaturation tendency of membrane proteins in aqueous solution, it is difficult to simulate the membrane like environment to maintain the correct conformation of membrane proteins in vitro, which results in the slower-growing research on the structure and function of membrane proteins and related ligand drugs than that of water-soluble proteins. Membrane protein stabilization technology is the premise of establishing high specificity, high sensitivity and high throughput drug screening methods for membrane protein ligands, which is of great significance. In this paper, some techniques for stable separation and purification of membrane proteins are reviewed, including detergents, artificial membranes, polymers, lentiviral particles and so on, as well as their specific applications in drug screening.

Panax notoginseng (PN) is one of the commonly used clinical medicines for cardiovascular diseases and possesses a variety of pharmacological effects. P. notoginseng saponins (PNS) are the most important bioactive components in PN. The purpose of this study was to explain the mechanism of PNS on molecular network level. 18 targets of the main medicinal ingredients of PNS were gained by virtual screening based on pharmacophores and data mining. A protein interaction network of PNS was constructed with 189 nodes and 721 interactions. By a graph theoretic clustering algorithm Molecular Complex Detection (MCODE), 14 modules were detected. Gene ontology (GO) enrichment analysis of the modules demonstrated that the roles of PNS played in cardiovascular disease related to multiple biological processes, which could represent the characteristics of traditional Chinese medicine (TCM) as a whole to regulate the disease. The results showed that the blood circulation and hemostasis efficacy of PN related with the biological processes such as positive regulation of cAMP metabolic and biosynthetic process, platelet activation and regulation of blood vessel size, regulation of T cell proliferation and differentiation and so on. Therefore, the module-based network analysis will be an effective method for better understanding TCM.
