ObjectiveTo investigate the relationship between carotid atherosclerosis and progressing stroke.Methods103 patients with acute cerebral infarction within the first 24 hours from onset were tested with carotid color doppler ultrasonography during the first week from admission. Univariate and multiple logistic regression analyses were performed to examine the relationship between carotid intima media thickness (IMT), plaque structure, the degree of artery stenosis and the early deterioration of cerebral infarction.ResultsPrevalence of carotid plaque and thickness of IMT in patients with progressing stroke were higher than that in non progressing patients. In logistic regression, presence of carotid plaque was independent predictors of progressing stroke. Plaque size, extent of artery stenosis and IMT were not included in the regression model.ConclusionPlaque structure and its chemical feature may be the cause of progressing stroke.

Chinese Journal of Practical Nursing 2012;28(22):68-70
ObjectiveTo explore the factors related to infections of intravenous catheter as well as preventive measures.MethodsIn 598 cases of patients with central venous catheterization,indwelling time,location,bacteriology were monitored among 130 patients with suspected venous catheter infection.ResultsIndwelling catheter lasts for 3 days at least,70 days at most.For 77 out of toual cases,microbiology culture of catheter tip and blood culture were positive,accounting for 12.88%.Detected pathogens were 151 in total.Gram-negative bacteria were 48(31.79%),gram-positive bacteria were 78(50.65%),fungal were 25 (16.56%).Among these,the most common pathogens were Staphylococcus epidermidis,Staphylococcus aureus,Candida and Acinetobacter,most of the bacteria had a high degree of drug resistance.The choice of position:infection rate of subclavian vein and basilic vein was lower than that of the superclavian vein and internal jugular vein,infection rate of catheterization time ≤ 13d was lower than that of ≥ 14d.ConclusionsThe choice of subclavian vein and basilic vein,standardization of puncture technical,strict catheter care,shortening of catheterization time and improvement of the general condition of patients can reduce catheter-reiated infections.The rational use of antibiotics is a critical measure to reduce vascular catheter infections of patients.
7.Study on Protective Effect of Glycyrrhiza uralensis Polysaccharide on CCl4 Induced Acute Liver Injury in Mice and Its Mechanism
China Pharmacy 2016;27(10):1322-1325
OBJECTIVE:To study the protective effect of Glycyrrhiza uralensis polysaccharide (GUP) on CCl4 induced acute liver injury in mice and its mechanism. METHODS:60 ICR mice were randomly divided into normal control group (normal sa-line),model group(normal saline),bifendate group(positive drug,100 mg/kg)and GUP high-dose,medium-dose and low-dose groups (400,200 and 100 mg/kg). They were given relevant medicine intragastrically once a day. 15 d later,acute liver injury model was induced by intraperitoneal injection of CCl4 in those groups except for normal control group,and liver index was deter-mined. The levels of AST and ALT in serum,the NOS,NO,SOD,GSH-Px and MDA levels in liver tissues were detected. RE-SULTS:Compared with normal control group,the liver index,the levels of AST and ALT in serum and NOS,NO and MDA in liver tissue increased in model group,while SOD and GSH-Px levels in liver tissue decreased(P<0.05);liver cells became swell-ing,degeneration and necrosis,showed obvious inflammatory injury. Compared with model group,the liver index of GUP groups decreased,there was statistical significance in GUP high-dose medium-dose groups (P<0.05);the levels of AST and ALT in se-rum and NOS,NO and MDA in liver tissue of mice decreased in GUP groups,while the level of SOD and GSH-Px in liver tissue increased(P<0.05);liver cellular swelling,degeneration and necrosis relieved,and pathological injury had been improved. CON-CLUSIONS:GUP has a certain protective effect on CCl4-induced acute liver injury in mice and its protective effect may be related to antioxidation,decrease of NOS and NO levels,and reduction of the production of free radicals.

9.Classification and evolutionary analysis of pollen allergens
Chinese Journal of Microbiology and Immunology 2010;30(1):56-59
Objective To classify all the plant pollen allergens, each allergen sequence available was compared with protein family database. After that, the appearance and taxonomic distribution of each protein family could be known. When made reference to evolutionary analysis, a regular rule of the distribu-tion of all plant pollen allergens could be concluded. Methods Protein family memberships of each allergen were assigned by comparing the sequences with the Pfam database. Representative members of the most a-bundant pollen allergen families were compared with the Uniprot database using the BLAST server. Acces-sion number of all the interesting homologous could be obtained and all the sequence information could be ac-quired by Batch Entrez. Finally, the evolutionary trees were drawn with the help of MEGA4.0 software. Re-sults One hundred and sixty-eight pollen allergens were classified into 26 protein families. Profilins, pollen _allerg_1 and EF hands constituted the most abundant pollen allergen families. Profilins and EF hands oc-curred in almost all allergenic plant families, whereas allergenic Expansins, FAD_binding proteins, Amb_V allergens and Thaumatins were confined to single taxon. Conclusion It is concluded that the highly con-served sequences of allergens families such as Profilin may be one of the most important reasons of the cross reactivities in allergic diseases. The classification of pollen allergens may be helpful to clinical practice and basic research.
