ObjectiveTo investigate the flora distribution and drug resistance status of nosocomial fungal infection in cancer hospitals for providing the scientific basis for clinical prevention and control.Methods The related clinical data and results of drug sensitivity tests of fungal infection in hospitalized patients from April 2006 to November 2010 were analyzed retrospectively.ResultsA total of 1011 strains of candida were isolated in five years, in which, Candida albicans (41.6％ on average) were the highest detection rate strains.The proportion of Candida albicans declined from 53.8％ in 2006 to 31.7％ in 2010, while the other non-Candida albicans increased from 46.2％ in 2006 to 68.3％ in 2010.In the General surgery, the Internal medicine,the Hepatobiliary surgery, and the Chinese and Western medicine, the number of candida were more than the other departments.The specimens were mainly isolated from sputum and swab, followed by blood specimens.In vitro susceptibility test results showed that: voriconazole, amphotericin B and 5-fluorocytosine showed high sensitivity and itraconazole, fluconazole showed high drug resistance to albicans.Conclusion Distribution of pathogens causing nosocomial fungal infection has changed, and the rates of fungal resistance were rising,so this situation should arouse the clinician's attention.

Objective To investigate the dynamic changes and drug resistance of fungal infection in our hospital during 2010 -2012 for guiding the clinical reasonable use of anti-fungal drugs .Methods The related clinical data and the drug sensitivity tests re-sults of fungal infection in the hospitalized patients from 2010 to 2012 were retrospectively analyzed by the WHONET 5 .6 soft-ware .Results Candida albicans was the major pathogen causing candida infection for these 3 years .The isolated specimens were mainly sputum and blood .In the departments of internal medicine ,general surgery and integrated Chinese and Western medicine ,the number of detected candida were more than that of the other departments .Five kinds of candida showed high sensitivity to ampho-tericin B and high resistance to itraconazole .Conclusion The distribution of pathogens causing nosocomial fungal infection has changed and the drug resistance rate is continuously rising .Therefore the dynamic monitoring and the study of fungal infection should be strengthened for reducing the occurrence of fungal infection in the patients with tumor .

Abstract Objective: To study the relationshiop between the HBV pre-c mutant and the clinical the, the host immunity. Methods: Mu-tation specific PCR(msPCR) was employed for detecting pre-c mutant in 92 cases with HBV-DNA positive;T subpopulations were determinedby APAAP immune-bridge assay; the cytokines (TNF?、 sIL-2R ) levels by ELISA. Results: 57 cases had Pre-c mutant, the rate was ahaut 62 %;pre-c mutant existed popularly in different e systems status, mainly in anti-HBe(+) serum. The reat increased with the deterioration of liverfunction, and was highest in fulminant hepatitis, the percentage of CD4 T lymphocyte and the ratio of CD4/CD8 were aignificantly lower in mu-tational group than in wild group,but CD8 T lymphocyte was obviously higher, the quantity of sera TNF? and sIL-2R in mutational group wereobviously higher than in wild group, both groups were obviously higher than control group. Conclusion:PreC 1896 mutant existed popularly inpatients with HBV infection. There were more serious disturbance in host immunity in mutant group. The mutant may be associated with the pre-ssare of host immune system.The mutant type virus could provoke host immunity resulting in severe liver damage.

Objective: To investigate the dynamic changes in the content of endothelin(ET) in the plasma of coronary heart disease(CHD) patients and the relationship between myocardial function and ET.Methods: The plasma ET levels of 62 CHD patients were measured by immunoradiometric assay(IRMA) at 12 h,24 h,48 h,96 h and 7 d after the attack of CHD.The left ventricular ejection fraction(LVEF) was detected by echocardiography and the cardiac function was assessed according to the NYHA classification criteria.Results: The plasma ET level was significantly higher in the CHD patients than in the healthy controls(P

Objective To explore the prevalence of ETS gene fusion in prostate cancer and its correlation with patient's clinicopathologic index.Methods Ninety-one samples from prostate needle biopsy cases with median age 75 (55-90) years and 18 samples from radical prostatectomy cases with median age 72 (63-81) years were collected from Oct.2010 to Feb.2012.TMPRSS2-ERG,TMPRSS2-ETV1 and TMPRSS2-ETV4 fusions were tested by multi-probe fluorescence in situ hybridization (FISH) assay.Fusion positive and negative cases were compared with age,TNM stage,Gleason score (median Gleason score 7 (6-9)),and PSA value (median PSA 33.4 μg/L,mcan PSA 118.8 μg/L).In needle biopsy cases,there were early stage 32 (34％),locally advanced prostate cancer 36 (40％),metastasis 23 (26％) ; in radical prostatectomy cases,there were 9 cases in T2 stage,8 cases in T3 stage,1 cases in T4a stage,respectively.Results TMPRSS2-ERG fusions were present in 14.3％ (13/91,95％ confidence interval,0.071-0.215)biopsy specimens and in 11.1％ (2/18,95％ confidence interval,0-0.256) radical prostatectomy specimens.No TMPRSS2-ETV1 or TMPRSS2-ETV4 fusions were found in any cases.Altogether,13 (86.7％)cases possessed deletion pattern.And 7 (46.6％) hold insertion pattern.5 cases had both deletion and insertion pattern.38.5％ (5/13) deletion pattern had distant metastasis.Except one metastatic case harbored both deletion and insertion pattern,there was no insertion pattern accompanied with metastasis.There were no differences between fusion positive and negative cases in the distribution of age (P =1.000),PSA (P =1.138),primary Gleason score (P=2.186),Gleason score (P=2.107),TNM stage (P=2.052) and Risk Degree (P=2.597).Conclusions The TMPRSS2-ERG fusion positive cases harbor more deletion pattern than insertion pattern.There are no differences between fusion positive and negative cases in the distribution of age,PSA,Gleason score,TNM stage and Risk Degree.

Objective To explore the effect of different indexes on evaluating insulin resistance in obese children. Methods Oral glucose tolerance test (OGTT) was performed in obese children (n= 61) and age - matched normal volunteers( n= 23) Serum glucose and insulin levels were determined at 0,30,60,120,180 min after OGTT, insulin resistance was estimated by homeostasis model assessment of insulin resistance (HOMA-IR). Indexes such as the ratio of area under the curve of glucose(AUCG)/area under the curve of insulin(AUCI), the ratio of fasting blood sugar(FBG) and fasting blood insulin (FINS) were meanwhile calculated. Results The level of serum FINS was significantly higher in obese children(P

Objective To detect levels of IL - 4 and INF - ? in induced sputum dynamically in children with mycnplasma pneamo-niae pneumonia( MPP), and to analyze the function of Th1 /Th2 cell factor immune response in the genesis and development of MPP, so as to evaluate the clinical value of induced sputum method in MPP research. Methods There were 38 cases who were diagnoses as MPP using 3% high osmotic pressure of saline water to ultrasonic atomizing inhalation for inducing sputum. ELISA was used to detect IL-4 and INF-?. Results The content of IL-4 in acute stage was higher than that in convalescence stage in induced sputum of MPP children. Severe stage was higher than mild stage. However, the comparison between acute and convalescence stage didn't have statistics difference in the content of INF-?, neither did the comparison between severe and mild stage. IL- 4/INF- ? in acute stage was higher than that in convalescence stage. Severe stage was higher than mild stage. In convalescence stage, the comparison of INF - ?, IL - 4, IL - 4/INF - ? between the severe and the mild didn' t have statistic significance. Conclusions IL-4 and INF - ? have participated in the monogenesis of MPP. The disequilibria of Th1 /Fh2 is existed in MPP and Th2 reaction predominates. So induced sputum analysis can be a better way to judge the light or heavy press degree of MPP practically, conveniently and sensitively.
