AIM:To investigate the effect of advanced glycation end products on inflammation in cultured cardiomyocytes.METHODS: Primary cardiomyocytes were isolated from Sprague-Dawley neonatal (1 to 2 days old) rats ventricles. The insulin resistant cardiomyocyte model was established. Neonatal rat ventricular myocytes were exposed to AGEs for 24 hours. TNF-? mRNA and PPAR-? mRNA expressions were determined by RT-PCR. Activation of NF-?B in the cells was examined by using immunocytochemistry. The ultrastructure of the cells was detected by transmission electron microscope.RESULTS: The exprssion of TNF-? mRNA and the activation of NF-?B increased, the expression of PPAR-? mRNA decreased compared with control group (P

Objective To investigate the epidemiology of drug-resistant tuberculosis (TB) in five rural counties of eastern China and analyze the biological,demographic and social risk factors.Methods Subjects of this study were all the diagnosed TB patients registered in the five study sites in Shandong Province,Jiangsu Province and Zhejiang Province during one year of 2008- 2009.Questionnaire interview was conducted in all the subjects to acquire the socio-demographic and clinical information.Sputum samples were collected for culturing and isolating of Mycobacterium tuberculosis (M.TB) strains.All the M.TB isolates were further tested for the susceptibility to first-line drugs including rifampin,isoniazid,ethambutol and strepomycin by proportion method.Mantel-Haenszel chi-square test,Fisher's exact test,ANOVA and nonconditional Logistic regression modeling were applied for data analysis.Results Among the total 380 M.TB isolates,105 were resistant to at least one of the first-line drugs.The total drug resistant TB prevalence was 27.6%.Multidrug-resistant tuberculosis (MDR-TB) was observed in 8.4% of newly treated TB patients,whereas it was 23.3%in previously treated TB patients.After adjusted by county,gender and age of the subjects,multivariate analysis showed that previous treatment history (OR=3.900,95%CI: 1.737-8.704),tuberculosis cavity (OR - 1.987,95 % CI: 1.001 - 3.942) were independent factors influencing the occurrence of MDR-TB.Conclusions The prevalence of drug resistant TB in rural area of eastern China is relatively low compared with the average level in China,while it is still higher than the global average level.The present study highlights that TB patients with previous treatment history,cavitaryTB are correlated with MDR-TB,and elderly patients are at high risk of MDR-TB.

The QCC campaign at the emergency center was themed as minimizing incidence of risky transport of critically ill patients,which aimed at continued quality improvement by means of conditions review,problem analysis,measures making,and procedure improvement.The incidence of risky transports dropped from 26% to 0.9% in six months.Another promising outcome was a sharp betterment of clinical nurse management. It has proved that QCC can effectively downsize risky transports of critically ill patients,making it a functional means to improve nursing quality.

Objective To investigate the impact of isoniazid (INH)-resistant Mycobacterium tuberculosis (Mtb) on the prevalence and dissemination of multi-drug resistant tuberculosis (MDR-TB).Methods A total of 251 patients diagnosed with tuberculosis in designated hospitals of Guanyun,Jiangsu and Deqing,Zhejiang from 2010 to 2011 were included in the study.The drug susceptibility tests (DST) were performed on all the Mtb isolates available from the sputum cultures.Mycobacteral interspersed repetitive units-variable number tandem repeats (MIRU-VNTR) was conducted for genotyping for all available Mtb isolates.Chi-square test,Fisher exact test,ANOVA and non-conditional Logistic regression modelling were applied for data analysis.Results Among 251 patients with Mtb isolates and DST results available,72 (28.7%) were resistant to INH,including 13 were INH mono-drug resistant.Of the remaining 59 INH-resistant Mtb,34 (13.5%) were resistant to rifampin TB and 25 were resistant to streptomycin and/or ethambutol.The clustering analysis based on MIRU-VNTR genotyping revealed 29 clustered genotypes (including 105 isolates) and 146 unique genotypes (including 119 isolates).Twentyfive clusters contained drug resistant Mtb and 16 clusters of them comprised by 37 INH-resistant isolates and 20 MDR-TB isolates,which accounted for 51.4% of the INH-resistant isolates and 58.8% of the MDR-TB isolates.Single factor analysis showed that sex,age,previous tuberculosis treatment history and sputum smear results were all related to INH-resistant tuberculosis and MDR-TB (all P < 0.05).Multiple factors analysis showed that previous tuberculosis treatment history was risk factor of MDR-TB (OR=8.40,95 %CI:3.342-21.105),while the risk factors of INH-resistant tuberculosis were previous tuberculosis treatment history (OR=3.52,95%CI:1.570-7.910),pulmonary caviry (OR=2.27,95%CI:1.075-4.799) and sputum smear results (OR=0.50,95%CI:0.275-0.892).Conclusions That INH-resistant strain may evolve to the MDR-TB after recent transmission is a possible trend.Patients with previous treatment history and advanced age are at high risk of INH-resistant tuberculosis and MDR-TB.

Objective To establish the quality standard for Yanyan syrup. Methods Thin layer chromatography ( TLC) was used for the qualitative identification of Puerariae Lobatae Radix and Scrophulariae Radix. High performance liquid chromatography (HPLC) was used to determine the content of puerarin on Diamonsil C18(200 mm×4.6 mm,5μm) column with mobile phase consisting of methanol-0.5% acetic acid (25:75) at a flow rate of 1.0 mL?min-1.The detection wavelength was set at 250 nm. Results TLC spots were clear and well-separated without negative interference.The linear range of puerarin was 3-120μg?mL-1( r=0.999 7) with an average recovery of 97.44% ( RSD=2.07%,n=6) . Conclusion The method for quality and quantity of Yanyan syrup is simple, specific, accurate and reliable.It can be used for the quality control of Yanyan syrup.
