Objective To predict the effectiveness of gentamicin combined with trisodium citrate for locking solution in preventing catheter-related bloodstream infection.Methods This is a retrospective study,ten kinds of common pathogens in catheter-related bloodstream infections were selected from medical intensive care unit (n =9) and cardiac care unit (n =1) between July 2011 and July 2012,and the diffusion method was used to analyze the inhibitory effect of gentamicin combined with trisodium citrate against tested pathogens.Results When trisodium citrate was tested alone,a certain antimicrobial activity could be detected from 10％ trisodium citrate,only Staphylococcus aureus and Staphylococci haemolyticus were inhibited,and then Enterococcus faecium was inhibited by 30％ trisodium citrate.Compared with trisodium citrate,gentamicin showed stronger antimicrobial activity.Staphylococcus aureus,Staphylococci haemolyticus,Enterococcus faecium and Escherichia coli could be inhibited by 0.32 g/L gentamicin and the antimicrobial activity was enhanced by increasing concentrations.The maximum activity was in 5 g/L gentamicin with 7-17 mm diameters.However,the antimicrobial activity of gentamicin didn't increase when combined with trisodium citrate,especially in 4％ trisodium citrate,the Staphylococci haemolyticus was not inhibited by all of the combinations with any concentration of gentamicin.In 0.32 g/L gentamicin,only the combination with 50％ trisodium citrate could inhibit the four kinds of pathogens (Staphylococcus aureus,Staphylococci haemolyticus,Enterococcusfaecium and Escherichia coli) with 8-21 mm diameters,while in 1 g/L,2 g/L,and 5 g/L gentamicin,these pathogens could be inhibited by the combination with only 10％ trisodium citrate,and the diameters were 5-24 mm,12-27 mm,and 17-28 mm,respectively.Conclusion Based on the data,gentamicin combined with trisodium citrate lock solution may play an important role in preventing catheter-related bloodstream infections caused by Gram-positive bacteria and Escherichia coli.

Abtract: Acute coronary syndrome is a common clinical and frequently occurring disease, belonging to the chest discomfort, heartache, and true heart pain of TCM category. The clinical observation shows that the heat and blood stasis, and poison damage heart nutrient is one of the important mechanisms of triggering coronary syndrome. Therefore, the method of promoting blood circulation to remove meridian obstruction and the Qing Ying detoxication was established as the basic treatment, and Danshen Tongluo Jiedu Decoction is applied as the main formula. According to the different types of disease and syndrome differentiation, flexible modification can achieve good efficacy. It is expected that these will provide new ideas and methods for clinical treatment of acute coronary syndrome.

Objective To investigate the expression level of CD226 mRNA in the peripheral blood mononuclear cells (PBMCs) of patients with systemic lupus erythematosus (SLE) and explore the relation between the gene expression and disease activity, and the relation between the gene expression and Gly307Ser polymorphism of CD226 was also examined. Methods CD226 gene was measured with real-time polymerase chain reaction (qRT- PCR) in PBMCs. The expression levels of CD226 gene in PBMCs were compared between 90 SLE patients and 30 healthy individuals. One-way ANOVA and pearson correlation were used for statistical analysis. Results The expression level of CD226 in the PBMCs of SLE patients (6.8±1.1) was significantly decreased compared to healthy individuals (26.5±6.7) (P＜0.01), while there was no association between mRNA level and genotype (P＞0.05). No correlation between ESR, CRP, ANA, SLEDAI scores, C3 and the expression level of CD226 gene was discovered. Conclusion In Hubei Chinese Han population, CD226-Gly307Ser locus is associated with the development of SLE, while T allele does not impact the expression of CD226 gene, thus the role of CD226 gene in autoimmune diseases should be explored in the future.

Objective To explore the effects ofDanshen Tongluo Detoxication Decoction on the inflammatory response of rats with bone marrow stem cell (BMSC) transplantation in acute myocardial infarction (AMI); To discuss its mechanism of action.Methods The whole bone marrow adherent method was adopted for BMSCs separation and culture. The AMI model was established by closing the left anterior descending coronary artery of SD rats.

Objective We conducted a survey on the awareness rate of stroke in Yangquan residents and analyzed factors affecting awareness to provide basic information for Yangquan residents to prevent and treat stroke in Shanxi.MethodsA questionnaire regarding awareness and basic knowledge of stroke was used in this study and applied to Yangquan residents.A cluster stratified sample of 7983 residents were questionnaired by cross-sectional method.Results7921 returned copies were valid.The awareness rate of stroke in 7921 selected Yangquan residents was 30.14％ (2387/7921). Upon the occurrence of stroke,the awareness rates of the way to see a doctor,the right department to look for medical care and test manners to diagnose the illness as stroke were relatively high in these investigated people,which were 74.03％ (5864/7921),78.17％ (6192/7921) and 84.04％ (6657/7921),respectively.However,the number of people who knew characteristic symptoms and complications of stoke,risk factors that cause stroke and how to treat stroke was 2021 (25.51％),841 ( 10.62％ ),and 902 ( 11.39％ ),respectively,which was relatively low. After multivariate analysis,the awareness rate of stroke in Yangquan residents was positively correlated with an education degree.ConclusionsYangquan residents know little about stroke.Therefore,it is necessary to increase the level of their knowledge regarding stroke by extended propaganda and encourage them to live a healthy life to be able to treat stoke in time and to reduce the possibility of stroke occurring.

Even though mutations in LMNA have been reported in patients with typical dilated cardiomyopathy (DCM) and atrioventricular block (AVB) previously, the purpose of this study was to disclose this novel genetic abnormality in one Chinese family with the atypical phenotype of progressive AVB followed by DCM with normal QRS interval. Genome-wide linkage analysis mapped the AVB gene in this family to a marker at chromosome 1q21.2, where the LMNA gene was located. Direct DNA sequence analysis revealed a heterozygous G to A transition at nucleotide 244 in exon 1 of LMNA, which resulted in an E82K mutation. The E82K mutation co-segregated with all affected individuals in the family, and was not present in 200 normal controls. Further clinical evaluation of mutation carriers showed that 5 of 6 AVB patients exhibited mild DCM with a late onset of age in the fourth and fifth decades. Ejection fractions were documented in 5 patients with DCM, but 4 showed a normal value of [Symbol: see text]50%. Echocardiography showed that atrial dilatation occurred earlier than ventricular dilatation in the patients. This study suggests that progressive AVB with normal QRS interval and accompanying DCM at later stages may represent a distinct type of DCM. The molecular mechanism by which the E82K mutation causes AVB as the prominent phenotype in DCM may be a focus of future studies.
