Objective To evaluate the prognostic factors of elderly patients with noscomial Candidemia in intensive care unit. Methods A retrospective study was carried out in 75 elderly patients with noscomial Candidemia from 2001 to 2008. Multivariate logistic regression analysis was performed to find the correlations of prognosis with clinical and biochemical parameters. Results A total of 75 Candida strains were isolated from blood. The proportion of non-albicans species reached to 70.7%. Fluconazole-resistant candidiasis was increased. Overall mortality rate was 48.0%.Multivariate logistic regression analysis showed that septic shock, comorbid bacteremia, higher serum creatinine and sequential organ failure assessment (SOFA) score more than 10 were independent predictors for in-hospital mortality (Ward=6.34, 5.15, 8.04, 6.82, all P＞0.05). Conclusions Noscomical Candidemia in elderly critical illness patients leads a high mortality, the proportion of nonalbicans species and fluconazole-resistant candidiasis increase. The blood culture and drug sensitive test should be performed routinely to provide proper evidence for antifungal therapy. Monitoring the high risk factors, effective and reasonable therapeutics are the guarantee for reducing the mortality induced by Candidemia.

BACKGROUND:Human-mammal chimeric liver chimera has been a vital significance for the proliferation and differentiation of bone marrow mesenchymal stem cells.
OBJECTIVE:To establish an animal model of human-rhesus chimeric liver using adult bone marrow mesenchymal stem cells.
METHODS:Adult bone marrow mesenchymal stem cells were isolated, purified and cultured for the sixth generation. The number of bone marrow mesenchymal stem cells was no less than 5×108. Bone marrow mesenchymal stem cells labeled with green fluorescent protein were transplanted into the liver of the embryo rhesus with pregnancy of 10 weeks under guided by type-B ultrasound. At the 1st and 3rd months of birth, the liver tissue of the infant rhesus was taken for biopsy. After routine pathological section, histological specimens were observed under fluorescence microscope to confirm if there were adult bone marrow mesenchymal stem cells positive for green fluorescent protein and their distribution, and detected by immunohistochemical staining to identify if human albumin expressed in the liver of infant rhesus.
RESULTS AND CONCLUSION:Fluorescence microscope observation indicated that at the 1st and 3rd months after birth, there were surviving bone marrow mesenchymal stem cells derived from human with green fluorescence in the liver of infant rhesus, and these cells migrated to form more concentrated distribution. The immunohistochemical results demonstrated that functional liver cells expressing human albumin were observed in the liver of infant rhesus at the 1st and 3rd months after birth, and their distribution was in accordance with bone marrow mesenchymal stem cells with green fluorescence. Human-rhesus chimeric liver can be established using adult bone marrow mesenchymal stem cells, which can generate functional liver cells in the liver of infant rhesus.

Objective To evaluate the early diagnostic values of soluble triggering receptor expressed on myeloid cell-1 (sTREM-1) in patients with ventilator associated pneumonia (VAP).Methods A total of 112 clinical suspicion VAP ventilator-associated pneumonia (VAP) patients accepted from January 2008 through December 2010 were enrolled for prospective and observational study.Two independent intensivists without aware of the results of the sTREM-1 assay separately made diagnosis of VAP present or absent depending on the clinical symptoms and results of microbial culture.Patients were categorized into two groups:VAP group (n =74) and non-VAP group (n =38).The levels of sTREM-1 in broncho-alveolar lavage fluid (BALF) collected with Gibot method in unemployment of bronchoscope and in serum were measured by enzyme-linked immunosorbent assay (ELISA) on the first day of suspected diagnosis.Comparison of sTREM-1 level between BALF and serum was made by t-test and Receiver Operating Characteristic (ROC) curve.Results A total of 112 clinical suspicion VAP patients admitted from January 2008 through December 2010 were enrolled for prospective and observational study.Two independent intensivists without aware of the results of the sTREM-1 assay made diagnosis of VAP present or absent depending on the clinical symptoms and results of microbial culture.Patients were categorized into two groups:VAP group (n =74) and non-VAP group (n =38).The levels of sTREM-1 in broncho-alveolar lavage fluid (BALF) collected with Gibot method in unemployment of bronchoscope and in serum were measured by enzyme-linked immunosorbent assay (ELISA) on the first day of suspected diagnosis.Comparison of sTREM-1 level between BALF and serum was made by t-test and Receiver Operating Characteristic (ROC) curve.Conlclusions In suspected VAP patients,measurement of sTREM-1 levels in BALF and in serum could help identify VAP in early stage.

Objective:To evaluate the clinical application value of gastrointestinal contrast-enhanced ultrasound combined gas injection method in verifying the location of nasointestinal tube in critically ill patients.Methods:Data of 60 critically ill patients who had the indications of indwelling nasointestinal tube were collected from September 1,2015 to September 1,2016 in the Intensive Care Unit of Zhejiang Provincial People(s) Hospital.The position of nasointestinal tube in patients who underwent bedside blind insertion would be confirmed routinely through gas injection auscultation method.After tube was inserted,its route was scanned by ultrasound with gas perfusion assistance.Afterwards,rapid gas perfusion was used until suspicious tube end position was determined.Furthermore,oral ultrasound contrast agent was injected into the tube if instantaneous strong echo of gas was observed in localized lumen,and contrast agent filling meant the placement being successful.Two methods of position confirmation of nasointestinal tube in critically ill patients included gastrointestinal contrast enhanced ultrasound combined gas injection and gas injection auscultation only,and the effect of the two methods was compared and confirmed by chest and abdominal X ray examinations to verify the location of nasointestinal tube below pylorus.Results:A total of 60 patients were included in this study,58 patients(96.7％)in gastrointestinal contrast enhanced ultrasound combined gas injection group were successfully positioned.Among them,the placements of tube in 56 cases were below pylorus,while 2 cases were above pylorus.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of location of gastrointestinal contrast enhanced ultrasound combined gas injection method were 96.6％,100％,100％,50％,96.7％ and of gas injection auscultation method were 74.1％,50％,97.7％,6.3％ and 73.3％.The differences of the sensitivity,specificity,negative predictive value and accuracy between the two methods were statistically significant (P ＜ 0.05).Conclusion:Gastrointestinal contrastenhanced ultrasound combined gas injection method is a safe,simple and convenient method with high sen-sitivity,specificity,negative predictive value and accuracy in confirming the location of the nasointestinal tube.

Objective To investigate the effect of geraniin on expression of Wnt3a protein and mRNA in bone marrow stromal cell (BMSC) from osteoporotic rats. Methods The model of osteoporosis (OP) was duplicated by ovariectomy in rats. BMSCs were isolated and cultured. BMSCs from shamed rats were routinly cultured and taken as normal control, and BMSCs from OP rats were divided into model group, 1μmol/L simvastatin positive group, and geraniin group (0.01, 0.1, 1, 10, 100 μmol/L), respectively. The methods of realtime-PCR and western blot were used to assay the protein and mRNA expression of wnt3a, respectively.Results As compared with normal control group, the protein and mRNA expression of wnt3a in model group were significantly suppressed;Compared with model group, 1 μmol/L simvastatin, and 0.1, 1, 10 and 100 μmol/L geraniin significantly increased the expression of wnt3a protein and mRNA. Conclusion It is suggested that geraniin activates wnt/β-catenin pathway though increasing the expression of signaling protein wnt 3a in BMSCs from OP rats. It would be beneficial to osteogenic differentiation of BMSCs and osteogenesis.

BACKGROUND: Rat models induced by unilateral nephrectomy combined with adriamycin are widely used in screening anti-drugs of glomerular sclerosis. However, few reports concerning this method on inducing rabbit model of glomerular sclerosisOBJECTIVE: To establish a rabbit model of glomerular sclerosis, and to observe the renal function and histopathological changes during model preparation. DESIGN, TIME AND SETTING: Randomized controlled animal experiment was performed in Laboratory Animal Center of Kunming General Hospital of Chengdu Military Region between December 2008 and May 2009. MATERIALS: Twenty-five Japanese big-ear rabbits, weighing 1.75-2.25 kg, half males and half females, were selected to establish glomerular sclerosis models, and randomly divided into normal (n=10) and model (n=15) groups. METHODS: The left kidney of rabbits in the model group was removed under anesthetized with 30g/L saline solution of sodium pentobarbital (1 mL/kg). Rabbits in the normal group underwent a similar surgical procedure without kidney removing. At 1 week after operation, 5 mg/kg adriamycin was injected into rabbits in the model group, 3 mg/kg adriamycin was reinjected 2 weeks later. Same volume of physiological saline was injected in the normal group. MAIN OUTCOME MEASURES: The renal blood biochemical indexes were detected prior to and at weeks 4, 6, and 8 after model preparation. One nephridial tissue was harvested from each group to undergo pathological observation at week 8 after the second medication. RESULTS: ①Kidney in the normal group presented slightly white, slightly tough texture with smooth surface. ②Pathological features of focal segmental glomerulosclerosis was showed in the model group under a light microscope, presented as extracellular matrix hyperplasia, mesangial region expansion, renal glomerular capillary wall ball mix adhesion, tubule degeneration, or even interstitial fibrosis, as well as interstitial infiltration of inflammatory cells. ③Compared to the normal group, the total protein and albumin was and decreased, triglyceride, total cholesterol, low density lipoprotein cholesterol, urea nitrogen, and creatinine were significantly increased in the model group. The urine protein content of rabbits in the model group was obviously increased at 4 weeks, gradually reached a platform after 8 weeks, which still greater than that of the normal group. ④SPECT showed that the glomerular filtration rate of the model group was notably decreased (33 mL/min) than the normal group (92.6 mL/min).CONCLUSION: The unilateral nephrectomy combined with adriamycin in rabbits results in the formation of glomerular sclerosis, renal function and 24 h urinary protein is more visible in the phase change.
