Objective To investigate the risk factors of pulmonary fungal infection in intensive care unit(ICU),and discuss the strategy of prevention and treatment.Methods Forty children with pulmonary fungal infection in ICU of Wuhan Children's Hospital from Jan.2003 to Jan.2007 were analyzed retrospectively,including primarily diseases,application of antibiotics,adrenal cortical hormone and virulence operation,therapy and turnover.Results All children were accepted the therapies of broad spectrum antibiotics and glucocorticoids for long time before definite diagnosis of pulmonary fungal infection.Seventy-five percent children were received invasive operations or therapies.Their average time of stayed in hospital was 37.8 d.The clinical symptoms and imaging examinations were untypical.Blastomyces albicans was the main pathogen.After the antifungal agents and supportive treatment used in time,35 cases(87.5%) were cured and 5 cases(12.5%) died.Conclusions The major risk factors of children pulmonary fungal infection are long-time use of broad spectrum antibiotics and glucocorticoids.The pulmonary fungal infection can decrease by rational use of broad spectrum antibiotics and glucocorticoids,decreasing the unnecessary invasive operations,strengthening the supportive therapies of micro-ecosystem,and applying the antifungal agents in time.

0.05).But after the treatment,there were significant increases in pa(O2),SaO2 and PCIS(Pa0.05).Conclusions Early application of hyperoxia liquid could decrease multiple organ anoxia and the damage of lipid peroxidation.It has obviously protective effects on multiple organ damage during ischemic reperfusion in infants with muggy syndrome.

Objective To study the therapeutic mechanism of Polygonum cuspidatum extract on the gouty arthritis induced by monosodium urate (MSU). Method Acute gouty arthritis rats model was induced by MSU. Twelve hours after modeling,the positive expression area and integral optical density of intercellular adhesion molecule-1 (ICAM-1) and nuclear factor-?B p65 protein (NF-?Bp65) in synovial membrane were observed by immunohistochemical assay. The effect of Polygonum cuspidatum extract on ICAM-1 and NF-?Bp65 was observed. Results There existed less expression of ICAM-1 and NF-?B p65 protein on synovial membrane in the normal group,and their expression was much increased in the model group. Polygonum cuspidatum extract in the dose of 360 mg/kg significantly reduced the positive expression area and integral optical density of ICAM-1 and NF-?Bp65 protein. Conclusion Polygonum cuspidatum extract can inhibit the abnormal expression and activation of ICAM-1 and NF-?Bp65 in synovial tissue,which may be an important therapeutic and preventive mechanism for gouty arthritis.

Objective To study the effectiveness and safety of methods of transurethral bipolar plasmakinetie prostatectomy for benign prostatic hyperplasia with large volume.Methods The transurethral bipolar plasmakinetic prostatectomy with Nesbit (Nesbit group,45 cases)and prying-up technique (pryhag-up group,60 cases)were performed in 105 patients of the prostatic volume of more than 60 g.The results could be obtained by comparing operative time,intraoperative and postoperative blood loss and the time of postoperative sustained washing of the bladder between the two groups.Results In Nesbit group,the efficiency of average cutting gland was (0.79±0.17)g/min,the average intraoperative blood loss was (3.87± 1.09)ml/g,the decrease in postoperative Hb within 24 hours was (6.84±3.96)g/L,the average time of postoperative continuous washing of the bladder was 72 hours,8 patients were given by blood transfusion.In prying-up group,the corresponding data were(1.16±0.20) g/min,(1.60±0.64)ml/g,(3.87±2.33 )g/L,36 hours respectively,none of patients was given by blood transfusion.There were statistically significant in two groups(P＜0.05).Conclusions The adoption of prying-up is more favorable compared with Nesbit method in the aspects such as less blood loss,shorter operating time,less lotion,more thorough resection of the gland,higher security.It is conducive to delivering lecture,and it enables the standard operational procedure available.

BACKGROUND: With mechanical ventilation widely used in intensive care unit, the ventilator associated pneumonia (VAP) has become a common and serious complication in critically ill patients. Compared with adults, the incidence of VAP and the mortality are higher in children in pediatric intensive care unit (PICU) because of immune deficiency, severe basic diseases, and increased use of artificial airway or mechanical ventilation. Hence it is of significance to study the epidemiology and changes of antibacterial susceptibility in order to reduce the incidence and mortality of VAP in children. METHODS: From January 2008 to June 2010, 2758 children were treated in PICU of Wuhan Children's Hospital. Among them, 171 received mechanical ventilation over 48 hours in PICU, and 46 developed VAP. The distribution and drug-resistance pattern of the pathogenic bacteria isolated from lower respiratory tract aspirations were analyzed. RESULTS: A total of 119 pathogenic microbial strains were isolated. Gram-negative bacilli (G-) were the most (65.55％), followed by fungi (21.01％) and gram-positive cocci (G+, 13.45％). Among them, the most common pathogens were Acinetobacter baummannii, Escherichia coli, Klebsiella pneumoniae, candida albicans and coagulase-negative staphylococci. Antibiotic susceptibility tests indicated that the multiple drug-resistances of G- and G+ to antibiotics were serious. Most of G- was sensitive to ciprofloxacin, amikacin, imipenem, meropenem, cefoperazone-sulbactam and piperacillin-tazobactam. The susceptibility of G+ to vancomycin, teicoplanin and linezolid were 100％. Fungi were almost sensitive to all the antifungal agents. The primary pathogens of VAP were G-, and their multiple drug-resistances were serious. CONCLUSION: In clinical practice we should choose the most sensitive drug for VAP according to pathogenic test.

BACKGROUND: With beta-lactam drugs and immunosuppressants widely used, the infection caused byAcinetobacter baumannii (Ab) has become more and more serious with multidrug resistant Acinetobacter baumannii (MDRAb) emerging and worsening rapidly. Compared with other patients, the incidence and multidrug resistance of MDRAb are higher in children in pediatric intensive care unit (PICU) because of immune deficiency, severe basic diseases, prolonged hospitalization and invasive operations. Hence it is significant to study the epidemiology and changes of antibacterial susceptibility in order to reduce the incidence of MDRAb in children. METHODS: A total 115 patients with MDRAb pneumonia and 45 patients with negative MDRAb (NMDRAb) pneumonia who had been treated from January 2009 to August 2011 were studied retrospectively at the PICU of Wuhan Children's Hospital. Clinical data were analyzed with univariate and multivariate Logistic regression. RESULTS: In 176 clinical strains ofAcinetobacter baumannii isolated, there were 128 strains of MDRAb, accounting for 72.73％. Drug susceptibility tests showed that the resistance rates of β-lactam antibiotics were more than 70％ except for cefoperazone sulbactam. The rates to carbapenems were higher than 90％. They were significantly higher than those of NMDRAb. Amikacin, levofloxacin, ciprofloxacin and minocycline had the lowest drug-resistance rates (<20％). Multivariate Logistic regression revealed that ICU stay, the time of mechanical ventilation, anemia, hypoproteinemia and the use of carbapenems were independent risk factors for MDRAb pneumonia. CONCLUSIONS: MDRAb is an important opportunistic pathogen to pneumonia in PICU, and its drug-resistance is severe. It increases significantly the mortality of patients. It is important to take the effective prevention measures for controlling it.
