Objective To evaluate the susceptibility of itraconazole-resistant Aspergillus fumigatus isolates to four other antifungal drugs.Methods Six strains of Aspergillus fumigatus were serially isolated from a patient with lung aspergilloma,who was resistant to itraconazole therapy.Clinical Laboratory Stan- dard Institute broth microdilution method M38-A and E-test were applied to test the susceptibility of A.fumi- gatus strains to amphotericin B,itraconazole,voriconazole,caspofungin and micafungin.Results With M38-A method,the minimal inhibitory concentration(MIC)of itraconazole was 0.5?g/mL for 2 strains and more than 16?g/mL for the other 4 strains;the MICs of amphotericin B and voriconazole were 1?g/mL and 0.25-1?g/mL respectively for all the 6 strains;and the minimal effective concentration(MEC)of caspofungin and micafungin were no more than 0.03?g/mL for all the 6 strains.Moreover,E-test results also revealed that caspofungin and voriconazole had a good antifungal activity against all the strains,including the 4 itraconazole-resistant ones.Conclusion The itraconazole-resistant A.fumigatus strains isolated from a patient with lung aspergilloma are susceptible to amphotericin B,voriconazole,caspofungin,and micafungin.

OBJECTIVETo evaluate the effect of nasogastric decompression tube after gastric cancer operation on the postoperative recovery.

METHODSA total of 174 patients with gastric cancer were prospectively enrolled from December 2009 to March 2011 and randomly divided into non-nasogastric tube control group(n=88) and nasogastric tube group(n=86). Postoperative symptoms, complications, recovery time, and quality of life during hospital stay were compared between the two groups.

RESULTSThe incidences of nausea(14.8% vs. 47.7%, P<0.01), sore throat(6.8% vs. 38.4%, P<0.01), bucking and foreign body sensation(3.4% vs. 20.9%, P<0.01), expectoration obstruction(36.4% vs. 55.8%, P<0.05) were significantly lower in nasogastric tube group than those in the control group. The intervals to ambulation and flatus were(1.46±0.58) d and(3.11±0.77) d in the non-nasogastric tube group, significantly shorter those in nasogastric tube group[(1.68±0.61) d and(3.75±1.03) d]. There was no anastomotic leak or bowel obstruction. The difference in bleeding was not statistically significant[3.4%(3/88) vs. 5.8%(5/86), P>0.05] between the two groups. The quality of life differed between the two groups(mean score, 3.36 vs. 2.78, P<0.01).

CONCLUSIONEarly removal of nasogastric decompression tube is safe and reasonable and can improve the quality of life during hospital stay.

Limit test of flavones in diterpene ginkgolides meglumine injection materials by UV-Vis and HPLC-DAD method was studied in this essay. The HPLC-DAD method has lower LOD (about 1% of the UV-Vis), that is, the sensitivity is higher than UV-Vis method. Through the analysis of the kinds of flavonoids ingredients in the samples by LC-MS, the three compounds with highest contents are kaempferol, quercetin and isorhamnetin. Kaempferol, quercetin and isorhamnetin were chosen as reference compounds for HPLC analysis, and the HPLC separation analysis was carried on an Agilent Eclipse plus C18 column (4.6 mm x 250 mm, 5 μm) with methanol and water containing 0.4% phosphoric acid (50: 50) as mobile phase, and the flow rate was 1.0 mL x min(-1). The detection wavelength was set at 360 nm. This method has good specificity, precision and reproducibility. The LODs of quercetin, kaempferide and isorhamnetin were 27.6, 22.3, 29.5 μg x L(-1). The average recovery was 87.9% (RSD 3.3%), 91.7% (RSD 3.1%), 88.3 (RSD 1.3%) for quercetin, kaempferide and isorhamnetin, respectively. Based on the 10 batches of sample results and sensitivity of different HPLC, the content of total flavonoids ingredients of diterpene ginkgolides meglumine injection materials was limited no more than 2 x 10(-5). This method is simple, quick and has good maneuverability, and could be used to the limit test of flavonoids in the diterpene ginkgolides meglumine injection materials.

Objective To evaluate the effect of continuous renal replacement therapy (CRRT) on the remove of inflammatory mediators and the function of endothelial cells in patients with multiple organ dysfunction syndrome (MODS). Methods Thirty patients with MODS were enrolled in this study. All of the patients underwent CRRT for at least 24 hours. Peripheral blood levels of IL-1β, IL-4, IL-6, IL-10, TNF-α, E-selectin, sVCAM-1, slCAM-1 and PAF-AH were measured at the beginning and 3, 6, 12, 24 h after initiation of CRRT. Results Nineteen patients survived after 14 days and 17 patients survived after 28 days during therapy. The clinical oxygenation and bemodynamics were improved after 6 h of CRRT. Among inflammatory mediators, the levels of TNF-α, IL-6, IL-10 rose gradually from the beginning [(462.24±331.03) ng/L, (106.39±90.82) ng/L, (124.51±118.39) ng/L), and reached the peak at 12 h [(887.88±975.46) ng/L, (132.01±118.14) ng/L, (167.01±161.66) ng/L], and the levels of IL-1β, IL-4 decreased from initiation of CRRT. But there were no significant differences in the levels of above cytokines between at the beginning and at the end of CRRT. There were significant differences in the levels of cytokines between survival and death group. The level of IL-6 in death group [(145.45±14.28) ng/L] was significantly higher than that in survival group [(106.03±10.86) ng/L]. The level of IL-10 in death group [(94.93±16.09) ng/L] was significantly lower than that in survival group [(143.06± 12.24) ng/L]. Levels of E-select, sVCAM-1 and sICAM-1 elevated from the beginning and reached the peak at 12 h, but no significant differences were found between intiation and the end of CRRT. The level of PAF-AH increased after initiation, and there was a significant difference between beginning and the end of CRRT. Levels of cytokines for endothelial cell function were significantly different, such as E-selectin [(287.13±42.70) μg/L vs (266.26±65.26) μg/L], sVCAM-I [( 1697.25± 475.24) μg/L vs (1488.10±691.67) μg/L], sICAM-1 [(975.33±142.50) μg/L vs (835.40±332.41) μg/L], and PAF-AH [(9.07±6.38 ) μg/L vs (16.32±8.95)μg/L]. Conclusions Clinical oxygenation and hemodynamics can be improved, and endothelial cell function can be improved partly by CRRT. There were no significant differences of inflammatory mediator levels between initiation and the end of CRRT. IL-6 and IL-10 can be used as predicators for prognosis of MODS patients.

Objective: To observe the prognosis of continuous renal replacement therapy (CRRT) in patients with multiple organ dysfunction syndrome(MODS). Methods: Thirty patients with MODS were enrolled in this study and were divided into two groups (survival group and death group) by their outcomes. All of these patients underwent CRRT for at least 24 h. The levels of interleukin (IL)-1β, IL-4, IL-6, IL-10 and tumor necrosis factor(TNF)-α were measured at the beginning and 3, 6,12 and 24 h after initiation of CRRT. Results: Among these thirty patients, the level of TNF-α came to peak at 12 h, and there was no significant difference between beginning and the end of CRRT. The level of IL-6 in death group was higher than that in survival group. There were correlations among numbers of complications, abnormalities of co-agulation and acute pathologic and chronic health evaluation Ⅱ(APACHEⅡ) separately. Conclusion: Clinical oxygenation and hemodynamics situation can be improved by CRRT, but there were no significant differences in levels of inflammatory mediators between initiation and the end of CRRT.

Objective HLA-G widely participates in immune tolerance by its combination with immunoglobulin-like tran-scripts IL-2 and IL-4 on the surface of dendritic cells (DCs).The aim of the article was to explore the effects of recombinant adnovirus-mediated HLA-G transfection in macaca mulatta immature dendritic cells on T cell proliferation . Methods Marrow blood was collected from macaca mulattas by the puncture needle after anesthesia .Density gradient centrifugation method was applied in separating mononuclear from the extracted blood on which CD 34+cells were collected and pu-rified by means of immunomagnetic separation .Small doses of cyto-kines were added to get the immature dendritic cells after induced dif-ferentiation of CD34+cells.After the recombinant adnovirus-mediated HLA-G transfection in macaca mulatta immature dendritic cells , observation was done on the viral infection efficiency and western blot was used in detecting the expression of HLA -G in immature den-dritic cells.Taking T cells in macaca mulatta as responders and DCs transfected by recombinant adnovirus -mediated HLA-G as stimu-lators, mixed lymphocyte test was conducted .T cells were divided into 5 groups: mDC group ( mature DCs ) , imDC group ( immature DCs), imDC(L) group(addition of 100 ng/mL lipopolysaccharide after getting imDC at 7th day) , imDC(V) group (imDCs infected by recombinant adnovirus-mediated HLA-G) , imDC( L+V) group ( imDCs infected by recombinant adnovirus-mediated HLA-G along with the addition of 100 ng/mL lipopolysaccharide in culture process ) . Results We obtained the immature dendritic cells and recom-binant adenovirus of HLA-G expressed in these cells .Flow cytometry showed DC purity was up to 92.3 %, imDC purity was up to 72.39%and positive percentage of CD 4+T was greater than 80%.In comparison with imDC group ,the proliferation of stimulated T cells in mDC and imDC(L) groups was obviously intensified (P<0.01).In comparison with imDC(V) group, the proliferation of stim-ulated T cells in imDC, mDC, imDC(L), and imDC(L+V) groups was obviously intensified (P <0.01).In comparison with imDC(L+V) group, the proliferation of stimulated T cells in mDC and imDC(L) groups was obviously intensified(P<0.01). Conclu sion Im-mature DCs infected by recombinant adnovirus can inhibit the proliferation of T cells effectively .

Objective To investigate the cause of an outbreak of tinea capitis in a primary school.Methods All of the exposed children were surveyed by physical examinations and mycological examina-tions,including KOH preparation and fungal culture.The environment was also investigated in the school.With molecular typing of M.canis isolated from the patients and the environment,random primer amplifica-tion polymorphic DNA(RAPD)method,specific amplification of subrepeat elements in ribosomal DNA non-transcribed spacer(NTS),and DNA sequencing in intertranscribed spacer(ITS)of rDNA were performed.Results The total number of exposed children was seventy-one,among which fourty-two were suffered from tinea capitis.The ratio between boys and girls was13∶1.The age of the patients ranged from3.5-10years old.Four patients bred cats or dogs as pets.Fourty-one patients had noninflammatory type of tinea capitis and one had inflammatory type.Under microscopy all affected hairs showed ectothrix infection.M.canis was isolated from the patients,as well as from carpets in gymnasium and pillowcases in the school.The patterns of all strains of M.canis were identical in both RAPD and PCR amplification of rDNA NTS region.The same DNA sequence was found in the ITS region of isolates from the patients and the environment.Conclusion The outbreak of tinea capitis was caused by M.canis.M.canis strains isolated from the patients and from the environment were probably the same origin.
