OBJECTIVE To investigate the incidence of nosocomial infection in ICU patients,risk factors.and measures to prevent infection.METHODS The nosocomial infection of ICU patients in the hospitals from Nov 2005 to Jun 2009 was investigated using the method of target monitoring.The nosocomial infection rate was regulated by the method of ASA.The invasive procedure and the associated infection rate were analyzed.RESULTS Among 833 inpatients in ICU,92 suffered from nosocomial infection,The nosocomial infection rate was 11.04%.and the nosocomial infection rate per day was 4.43% after modified by the method of ASA.The incidence of patients was 5.37%.Totally 145 strains of bacteria were isolated,and the dominant pathogens were Gram-negative bacilli(56.55%).CONCLUSIONS The patients in ICU are susceptible population of nosocomial infection,A.baumannii is the dominating pathogen to cause nosocomial infection in intensive care units.Target monitoring in ICU is an effective surveillance method to reduce the prevalence of nosocomial infection.

Objective To research correlation of serum protein spectrometry and lymphoma markers for diffuse large B cell lymphoma (DLBCL) patients. Whether there is relative between the protein and prognosis will be further researched. Methods Serum protein spectrometry of 62 DLBCL patients was detected by the SELDI-TOF-MS technique and Weak cation exchange 2 (WCX2) chip. Lactate dehydrogenase (LDH) was detected by biochemistry method. Beta-2-microglobulin (β2-MG) and cancer antigen125(CA125)were detected by enzyme-linked immunosorbent assay (ELISA). The level of LDH, β2-MG and CA125 for DLBCL patients between 11×103~12×103 protein expressed positively and negatively was analyzed. Meanwhile,correlation analysis and survival analysis were done. Results LDH, β2-MG and CA125 in 11×103~12×103protein expressed positive group were (523.30±435.96)U/L, (3.23±1.24)mg/L, (81.07±61.39)U/L respectively,and they were higher than that in negative group (P<0.05). 11×103~12×103 protein was positive correlated to LDH, β2-MG and CA125 (P<0.01). The survival time in 11×103~12×103 protein expressed in positive group,in which median survival time was 11 months, was shorter than that in negative group(P <0.01). The survival time in LDH normal group was longer than that in increased group(P <0.01). The survival time of β2-MG and CA125 had no significant difference between increased group and normal group. Conclusion LDH and 11×103~12×103 protein are expected to be prognosis indicators for DLBCL patients.
