[Analysis on variance of common pathogenic bacteria and drug resistance in children in Chengdu area from 2001 to 2006].

Objective: To investigate the variance and drug resistance of pathogenic bacteria isolated from children with infectious diseases seen between 2001 and 2006 in Chengdu area.

Methods: A total of 2888 pathogenic bacterial strains isolated from children in Chengdu Children's Hospital from 2001 to 2006 were analyzed. Tests were performed according to the guidelines of National Committee for Clinical Laboratory Standards (NCCLS) of the United States.

[Distribution and drug resistance of pathogenic bacteria in children with lower respiratory tract infection from Chengdu Children's Hospital between 2001 and 2006].

Objective: To investigate the distribution and the changes of drug resistance of common pathogenic bacteria in children with lower respiratory tract infection (LRTI) of Chengdu.

[Determination of the lung function by impulse oscillometry in 549 healthy children in Chengdu area].

Objective: Impulse oscillometry (IOS) is a new method for determination of breathing mechanics, which features convenient operation, good repeatability and wider range analysis. As there is no standardized normal value in China at present, this study will provide a normal value of lung function determination by impulse oscillometry for children in Chengdu area.

Method: Totally 549 children were chosen at random from Chengdu area, with 292 boys and 257 girls who were 4 to 14 years old.

[Gene expressions of xylosyltransferase and heparanase in renal tissue of rat with adriamycin nephropathy and relevance for proteinuria].

Objective: To evaluate the roles of P-D-xylosyltransferase I (XT-I) and beta-D-endoglycosidase heparanase (Hpa) in renal tissue with the development of adriamycin (ADR) nephropathy and relevance for proteinuria.

Methods: 150-200 g Sprague-Dawley rats (n=10 per group) were used to make the nephropathy model induced by tail intravenous injection of 6 mg/kg ADR. Rats were housed in metabolic cage for 24 hours so as to collect the urine prior to disease induced and at day 7, 14 and 21 following disease induction.
