Objective To explore the treatment and diagnostic value of combined detection of high sensitivity C reactive protein(hs-CRP) and D-dimer (DD) levels for carotid artery plaque (CAS) in patients with acute cerebral infarction(ACI).Methods 48 patients with ACI were selected as the observation group,while 48 healthy people who excluded ACI were selected as the control group.The vascular ultrasonography and serum levels of hs-CRP and DD were detected within 3 days,and the observation group was classified according to TOAST.Results The hs-CRP and DD levels in the observation group were (7.88 ±2.54)mg/L and (1 286.2 ±233.4) μg/L,respectively,which were significantly higher than (1.14 ± 0.32) mg/L and (462.8 ± 147.2) μg/L in the control group (t =15.53,20.67,all P ＜ 0.05).The differences of hs-CRP and DD levels in different TOAST subtypes ACI patients were not statistically significant(P ＞0.05).The hs-CRP level was positively correlated with the number of instability carotid plaque(r =0.465,P =0.000),and DD level had no significant correlation with the number of instability carotid plaque.Conclusion Elevated serum hs-CRP and DD levels in ACI patients confirmed its participation in the acute inflammatory response,and hs-CRP can better reflect the instability of ACI patients with CAS.

OBJECTIVE To investigate predisposing factors of candidemia in nosocomial infections.METHODS To retrospectively review the clinical features of 120 cases,including 59 who developed candidemia and 61 cases with bacteremia during the period of 1990-2004.RESULTS The incidence of candidemia was stable over a 14-year period.Candida albicans remained the predominant Candida species recovered(30.5%),followed by C.tropicalis(25.7%),C.glabrata(12.9%),C.parapsilosis(12.9%) and others(17.1%).Of the total 59 cases of candidemia,were administrated by broad spectrum antibiotic therapy for long time,urinary catheters,malignant tumor,etc.Multivariate analysis showed that candidemia was related with many factors.CONCLUSIONS C.albicans was the major pathogen in our hospital during 14 years;the candidemia is related with the use of quinolones,ventilator,central venous catheters and radiation-chemotherapy(P

Objective To evaluate the in vitro activity of daptomycin, vancomycin, teicoplanin, tigecycline, ceftobiprole and linezolid against 499 strains of blood-isolated gram-positive cocci. Methods Determination of the minimal inhibitory concentration (MICs) of daptomycin with microbrothdilution method and the MICs of other 9 antimicrnhial agents with agar dilution method against 499 strains of blood-isolated gram positive cocci was carried out. The data was analyzed with WHONET 5.4 software. Results The susceptibility rates of staphylococci to daptomycin, tigecycline, linezolid, ceftobiprole, vancomyein and teicoplanin were 100%. All staphylococcus strains were inhibited by daptomycin at a MIC of 1 mg/L. The MIC50 and MIC60 of daptomyein were both 0.5 mg/L against methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant Staphylococcus coagalase-negative (MRSCnN). Among Enterococcus spp, the highest MIC of daptomycin was 4 mg/L. The MIC50 and MIC90 of daptomycin were both 2 mg/L against E.faecalis, whereas they were 2 mg/L and 4 mg/L against E.faecium. One strains of linezolid-resistant E.faecalis(MIC:8 mg/L)was susceptible to daptomycin (MIC: 1 mg/L). Three strains of E.faecium carrying vanA gene with vancomycin MICs above 32 mg/L and teicoplanin MICs also 32 mg/L were susceptible to daptomycin, tigeeycline and linezolid. The MIC range of daptomycin against Streptococcus pneumoniae and Streptococcus viridans was 0.032-0.25 mg/L and 0.125-1.000 mg/L separately. Conclusions Daptomycin has excellent in vitro activity against common gram-positive pathogens isolated from blood. It may be a good choice for clinicians to treat drug-resistant gram-positive cocci.

Objective To study Kaposi's sarcoma-associated herpesvirus(KSHV)infection in chronic hepatitis B(CHB)patients and its correlation with hepatitis B virus(HBV)replication and treatment-related factors.MethodsEnzyme-linked immunosorbent assay(ELISA)with recombination protein KSHV ORF65 was employed to detect the KSHV antibody and real-time polymerase chain reaction(PCR)was performed to detect KSHV DNA and HBV DNA in CHB patients.Age,HBV replication and licorice preparation treatment of patients were further analyzed.Comparison of rates was done using X~2 test.Results KSHV ORF65 antibody positive rates were 27.3% in 161 male CHB patients and 30.0% in 50 female patients(X~2=0.135,P＞0.05).The KSHV infection rates were increased with age,but this tendency was not obvious in patients older than 40 years old.The highest infection rate was in age group of 31-40 years old which was 37.1%.The positive rate of HBV DNA in CHB patients with KSHV infection was 73.5%,which was 56.3% in uninfected patients(X~2=3.969,P＜0.05).The average plasma level of KSHV DNA in patients treated with licorice preparations was 204.7 copy/mL and that in patients without licorice preparation treatment was 533.9 copy/mL.Eight patients were KSHV DNA positive(KSHV DNA＞ 100 copy/mL)in 16 patients treated with licorice preparations and 23 were positive in 33 patients without licorice preparation treatment.Conclusions The KSHV infection rates are increased with age of CHB patients.KSHV infection may interfere with HBV replication and licorice preparations may suppresss KSHV replication in vivo.

Objective To compare the in vitro activity of cefminox with other antimicrobial agents against clinical Escherichia coil, Klebsiella pneumoniae isolates and Bacteroides species. Methods MICs of sixteen antimicrobial agents against 945 Escherichia coli and 588 Klebsiella pneumoniae isolates from 15 teaching hospitals and MICs of four antimicrobial agents against 50 Bacteroides species isolates were determined by agar dilution method. WHONET 5.4 software was used to analyze the data. Results Among 1533 Escherichia coli and Klebsiella pneumoniae isolates, 628 isolates produced neither extended-spectrum beta-lactamases (ESBLs) nor AmpC, while 837 isolates produced only ESBLs and 68 isolates produced AmpC enzymes. The susceptibility rate of cefminox against non-ESBLs-producing or ESBLs-producing isolates was above 90%. MIC_(50) of eefminox was 2-4 fold lower than cefometazole and 8-16 fold lower than cefoxitin. MIC50 of cefminox was 2-8 fold lower than cefometazole and 8-16 fold lower than cefoxitin. Against ESBLs-producing isolates, the in vitro activity of cefminox was superior to the third and fourth generation cephalosporins, aztreonam, cefoperazone/sulbactam, levofloxacin, amikacin and inferior to carbapenems. Its activity was similar to piperacillin-tazobactam. The susceptibility rate of cefminox against AmpC-producing isolates was less than 20%. The susceptibility rate of cefminox against Bacteroides species was 90%, which was higher than that of cefometazole (50% -70%) and penicillin (0%) and similar to that of metronidazole. Conclusion Cefminox exhibites good activity against ESBLs-producing and non-ESBLs-producing Escherichia coli and Klebsiella pneumoniae isolates and Bacteroides species, which indicates that cefminox could be one of the options for the treatment of infections caused by these organisms.

Objective To investigate antimicrobial resistance among gram-positive cocci in China in 2006.Methods From Jun 2006 to Dec 2006,674 consecutive and non-repetitive gram-positive bacteria were collected from 7 teaching hospitals.The minimal inhibitory concentration(MICs)of antibacterial agents were determined by agar dilution method.Results The prevalence of penicillin.resistant(ease)and pemcllhn. intermediate S.pneumoniae(PISP)among 100 isolates was l%and 19%,respectively.Teicoplanin and vancomycin were the most active agents against S.pneumoniae.97% and 98% S.pneumoniae isolates were susceptible to levofloxacin and moxifloxacin,respectively.The susceptibility of amoxicillin/clavulanic acid, ceftriaxone and chloramphenicol are 96%,87% and 73%,respectively.The susceptible rates of penicillin. susceptible S.pneumoniae(PSSP)to cefprozil and cefaclor were 62% and 55.7%,respectively.All the PISP and PRSP isolates were resistance to the two antibiotics.The susceptibility to macrolides,trimethoprim/ sulfamethoxazole and tetracycline was lower than 35%.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA)and methicillin.resistant coagulase-negative Staphylococci(MRSCON)was 48%(33%-84%)and 81%(69%-94%),respectively.The susceptible rates of MRSA to trimethoprim/ sulfamethoxazole,chloramphenicol,rifampin,and the other antibiotics in this study were 72%,66%and 45%,respectively.The susceptible rate of MRSA to marcrolides,aminoglycosides,tetracyclines and quinolones were not more than 18%.56%(30%-86%)of E.faecalis and 80%(50%.100%)of E.faecium were highly resistant to gentamicin.The susceptibility of E.faecalis to all the antibiotics except chloramphenicol and tetracycline were higher than E.faecium.All isolates of S.aureus,CoNS and E.faecalis tested were susceptible to vacomycin and teicoplanin.There were two vacomycin.resistant E.faecium strains isolated from Hangzhou.Conclusions Antimicrobial resistance patterns of gram.positive cocci differed in different regions.The resistance of gram-positive cocci to the antibiotics in this study this year was a little higher than the data of the year of 2005.Teicoplanin and vancomycin remained very high activity to gram-positive cocci.

Objective To explore the immune mechanism of negative results of immune tests of schistosomiasis japonica pa?tients. Methods Totally 142 schistosomiasis patients(positive stool examinations)of Poyang Lake region were tested by ELI?SA method,and the ROC curve was applied to determine the high and low response of the patients. The levels of cellular immu?nity and cytokines of high and low responders were compared. Results Totally eight schistosomiasis patients were found as low responders. Besides SWAP?IgA(t= -1.588,P > 0.1),the levels of isotype antibodies were significantly lower in the low re?sponders compared with those in the high responders(t = -14.517 to -2.866,all P < 0.05). In the low responders,the propor?tion of CD3+T was increased;and the proportions of CD4+T,CD8+T,CD4+CD25+Treg,and the ratio of CD4+/CD8+ were all de?creased,but all of them were not significant(t = -1.72 to 0.974,all P > 0.05)compared with those in the high responders. The differences of IFN?γ and IL?10 between the high and low responders were both not significant(t= -2.426 to 0.216,all P >0.05). Conclusions There is a significant difference between the high and low responders only in the levels of isotype antibod?ies. One of the reasons of low response in the immune tests is the much lower antibody level after the antigen?antibody compound is completely formulated.

Objective To investigate distribution and antimicrobial resistance among nosocomial pathogens from 13 teaching hospitals in China in 2009. Methods Non-repetitive pathogens from nosocomial BSI, HAP and IAI were collected and sent to the central lab for MIC determination by agar dilution method.WHONET5.6 software was used to analyze the data. Results A total of 2 502 clinical isolates were collected. The top three pathogens of BSI were Escherichia coli [27. 1% (285/1 052 )] , coagulase-negutive staphylococcus [12. 6% ( 133/1 052)] and Klebsiella pneumoniae [10. 8% ( 114/1 052)]. The top three pathogens of HAP were Acinetobacter baumannii [28. 8% (226/785)], Pseudomonas aeruginosa [16. 1% (126/785)] and Klebsiella pneumoniae [14.6% (115/785 )] . The top three pathogens of IAI were Escherichia coli[31.0% ( 206/665 )], Klebsiella pneumonia [11.3% ( 75/665 )] and Enterococcus faecium [10. 8% (72/665)]. Against Escherichia coil and Klebsiella spp. , the antimicrobial agents with higher than 80% susceptibility rate included imipenem and meropenem (98. 1%-100% ), tigecycline (95.3%-100% ), piperacillin-tazobactam ( 88.6% -97. 1% ) and amikacin ( 88. 3% -92. 5% ). Against Enterobacter spp. , Citrobacter spp. and Serratia spp. , the susceptibility rates of tigecycline were 93.5% -100% whereas the value of imipenem and meropenem were 92.9% -100%. Other antimicrobial agents with high activity included amikacin ( 85.2% -96. 7% ), pipcracillin-tazobactam ( 82.4% -96.4% ), cefepime ( 79. 6% -96. 7% ) and cefoperazonc-sulbactam (78. 7%-90. 0% ). Polymyxin B showed the highest susceptibility rateagainst Pseudomonas aeruginosa ( 100% ), followed by amikacin ( 81.9% ) and piperacillin-tazobactam (80.1% ). Polymyxin B also showed the highest susceptibility rate against Acinetobacter baumannii (98. 8% ), followed by tigecycline (90. 1% ) and minocycline (72. 0% ). The incidence of carbapenemresistant Acinetobacter baumannii was 60. 1%. The MRSA rate was 60. 2% and the MRSCoN rate was 84. 2%. All Staphylococcus strains were susceptible to tigecycline, vancomycin, teicoplanin and linezolid except for one isolate of Staphylococcus haemolysis with intermediate to teicoplanin. Two Enterococcus faecalis isolates which were intermediate to linezolid and one Enterococcus faecium isolate which was resistant to vancomycin and teicoplanin was found in this surveillance, while the MICs of tigecycline against these three isolates were 0. 032-0. 064 μg/ml. Conclusions Tigecycline, carbapenems, piperacillin-tazobactam,amikacin and cefepime remain relatively high activity against nosocomial Enterobacteriaceae. Pseudomonas aeruginosa exhibite high susceptibility to polymyxin B, while Acinetobacter baumanni shows high susceptibility to polymyxin B and tigecycline. Tigecycline, vancomycin, teicoplanin and linezolid remain high activity against nosocomial gram-positive cocci.
