Objective To investigate the distribution and drug resistance of pathogens in cancer patients with nosocomial infections. Methods Pathogens isolated from cancer patients with nosocomial infections in Zhejiang Cancer Hospital from 2004 to 2008 were analyzed. Results Totally 3454 strains of pathogens were isolated, including 1900 strains of Gram-negative bacilli (55.0%), 838 strains of fungi (24.3%), and 716 strains of Gram-positive bacteria (20.7%). Pathogenic bacteria Escherichia coli and Candida albicans were isolated mainly from surgical wound, urinary tract, respiratory tract and oral cavity. The drug resistant rates for Gram-negative Escherichia coli and Gram-positive staphylococci were high, and Candida albicans was sensitive to all antifungal drugs. Conclusion Opportunistic pathogens account for most nosocomial infections in cancer patients, and some of them are of high-level resistance to antimicrobial agents.

Objective To discuss the risk factors of progressive hemorrhagic injury(PHI)in patients with craniocerebral injury.Methods Clinical data of 149 patients with closed craniocerebral injury were retrospectively analyzed,and the patients were divided into PHI group (42 cases)and non -PHI group (107 cases)according to PHI appeared or not.The patients were immediately given CT scan after admitted,the first CT review was given in the non -PHI group within routine 4 -8h after first CT scan,and due to deterioration of clinical symptoms,the PHI group was given CT review in advance.The intracranial hematoma volume changes between first CT and first CT review in the two groups were observed,then clinical symptoms,signs,biochemical indicators and CT performance in the two groups were compared,and analyzed risk factors of PHI.Results The intracranial hematoma volume showed in CT scan,first CT review and increment volume of the PHI group were significantly higher than the non -PHI group [(14.59 ±4.60)mL vs.(7.28 ±2.94)mL,(25.92 ±8.84)mL vs.(8.35 ±3.41)mL,(10.20 ±3.45)mL vs. (2.10 ±0.65)mL],the differences were significant (t =6.796,11.894,9.367,all P <0.05).Logistic regression analysis showed that pupil dilation,consciousness disturbance,intracranial hematoma volume >10mL were major risk factors of PHI (P <0.05).Conclusion In closed craniocerebral injury,we should pay more attention on PHI if patients with age >50 years old,mydriasis,conscious disturbance,intracranial hematoma volume >10mL in first CT scan.
