Objective To investigate the effect of different etiology on the serum level of carbohydrate antigen 125 (CA125) in elderly patients with chronic congestive heart failure (CHF), and to assess any correlation of CA125 with serum level of B-type natriuretic peptide (BNP). Methods The 155 aged patients with New York Heart Association (NYHA) class Ⅲ or Ⅳ were enrolled and grouped into four reasons of hypertension, coronary heart disease (CHD), cardiomyopathy and other reasons, and 25 healthy old persons as control.CA125 and BNP levels were measured by automatic chemiluminescent immunoassay and enzyme immunoradiometric assay, respectively. Results CA125 level in patients with CHF was (83.4±6.6)U/L for hypertension, (36.8±1.4)U/L for CHD, (38.1±1.6)U/L for cardiomyopathy and (38.4±1.4)U/L for other reasons, which significantly higher than for healthy controls [(14.3±1.15) U/L, P＜0.05].Especially, CA125 level in hypertension group was notable higher than in other reasons of group (P＜0.05), and was positively related to BNP level (r=0.67,P＜0.05). Conclusions Serum CA125 level is a predictor for clinical pathogen of CHF.Therefore, it may be a useful additional marker for the evaluation of clinical treatment of these patients

OBJECTIVE: To evaluate changes of VEGF in skin after blunt injury. METHODS: The rats of injury groups were subjected to skin blunt injury by free-falling iron hammer. The samples taken at 1 h, 3 h, 6 h, 12 h, 1 d, 3 d, 5 d, 7 d, 9 d after injury were studied by immunohistochemistry and MIAS image analysis system. RESULTS: In the skin of normal control group the expression level of VEGF was low. The increase of VEGF could be observed at 1 day after injury, reached peak at 7 days and declined at 9 days. CONCLUSION Blunt injury in the skin could induce the expression of the VEGF. Moreover, the change pattern of VEGF level was quite regular with time and could be used to estimate the time after skin injury.

BACKGROUNDAcinetobacter baumannii has emerged as an important pathogen related to serious infections and nosocomial outbreaks around the world. However, of the frequently used methods, pulsed-field gel electrophoresis (PFGE) and amplified fragment length polymorphism (AFLP) in Acinetobacter baumannii genotyping lack the direct molecular proof of drug resistance. This study was conducted to establish a typing method based on drug resistant gene identification in contrast to traditional PFGE and AFLP in the period of nosocomial epidemic or outbreak.

METHODSFrom January 2005 to October 2005, twenty-seven strains of Acinetobacter species from Intensive Care Units, the Second Affiliated Hospital in Ningbo were isolated, including both epidemic and sporadic events. Susceptibility test, PFGE, AFLP and drug resistance gene typing (DRGT) were carried out to confirm the drug resistance and analyze the genotyping, respectively. PFGE was used as a reference to evaluate the typeability of DRGT and AFLP.

RESULTSTwenty-seven strains of Acinetobacter displayed multiple antibiotic resistance and drug resistant genes, and beta-lactamase genes were detected in 85.2% strains. The result of DRGT was comparable to PFGE in Acinetobacter strains with different drug resistance though a little difference existed, and even suggested a molecular evolution course of different drug-resistant strains. AFLP showed great polymorphism between strains and had weak ability in distinguishing the drug resistance.

CONCLUSIONCompared to AFLP and PFGE, DRGT is useful to analyze localized molecular epidemiology of nosocomial infections and outbreaks, which would benefit clinical diagnosis and therapy.

OBJECTIVETo evaluate total antioxidant capacity (TAC) of seminal plasma in fertile and infertile men and understand the relation between seminal plasma TAC and male fertility.

METHODSTwo hundred and twenty-five infertile men were divided into 10 cases of obstructive azoospermic men, 42 cases of non-obstructive azoospermic men,20 cases of oligozoospermic men, 78 cases of asthenozoospermic men, 57 cases of oligoasthenozoospermic men, and 18 cases of normozoospermic men, then 28 fertile men were taken as the control. The seminal parameter analysis was performed by computer-assisted semen analysis (CASA) system. Seminal plasma TAC was measured using spectroscopic analysis.

RESULTSSeminal plasma TAC were (1.71 +/- 1.33) U in obstructive azoospermic men, (12.73 +/- 9.44) U in non-obstructive azoospermic men, (10.85 +/- 6.64) U in oligozoospermic men, (13.88 +/- 8.24) U in asthenozoospermic men, (11.20 +/- 7.02) U in oligoasthenozoospermic men, (18.07 +/- 8.73) U in normozoospermic men, and (19.82 +/- 6.33) U in fertile men. There was no significant difference in TAC between normozoospermic men and fertile men (P > 0.05). Compared with fertile men, seminal plasma TAC in other infertile groups was significantly lower (P < 0.01). There were significantly made positive correlation between seminal plasma TAC and sperm density (r = 0.182, P < 0.05), as well as sperm with grade a (r = 0.150, P < 0.05).

CONCLUSIONSeminal plasma TAC is closely related to male fertility, and the decreased level of TAC in seminal plasma may be one of the causes of male infertility.
