Objective To investigate the utility of combined test of neutrophil CD64 and C-reactive protein(CRP)for early diag-nosis of burn sepsis.Methods A prospective study was conducted in 76 hospitalized burn patients,including three groups:burn sepsis(n=27),local infection(n=31)and controls without bacterial infection (n=18)based on their diagnosis.Blood samples were collected within 24-48 h after hospital admission for analysis of neutrophil CD64,CRP,white blood cell count (WBC), neutrophils percentage (N)by flow cytometry,and bacterial culture.These parameters were re-evaluated for the patients in sepsis group 7 and 14 days after antibiotic therapy.Results Neutrophil CD64,CRP,WBC and N were significantly higher in sepsis patients than the corresponding values in the patients with local infection or control patients (P < 0.01 ).Neutrophil CD64 and CRP in the patients with local infection were significantly higher than those in the control patients without bacterial infection (P < 0.01).Neutrophil CD64 was positively correlated to CRP.Neutrophil CD64 and CRP decreased 7 days after an-tibiotic therapy,but the difference was not statistically significant compared to the pretreatment levels.Neutrophil CD64 and CRP decreased significantly 14 days after antibiotic therapy compared to the pretreatment levels (P < 0.01),but still higher than the levels in the control group.The receiver operating characteristic (ROC)curve of CD64 + CRP combined test,CD64, CRP,WBC,N for detecting bacterial infection showed an area under curve (AUC)of 0.952,0.923,0.904,0.756 and 0.728,respectively.Conclusions Neutrophil CD64 is useful in early diagnosis of burn sepsis.The expression of neutrophil CD64 does not have significant difference between gram-positive and gram-negative bacterial infections.Combined test of neutrophil CD64 and CRP can improve the efficiency for diagnosis of burn sepsis.

A biodegradable modified guar gum microsphere was prepared for the first time by ionic gelation of the guar gum derivative containing quarternary ammonium group with tripolyphosphate at room temperature in the absence of emulsifying agent or organic solvent. Its average particle diameter was about 140 microm and the particle size had a narrow and normal gauss distribution. From the loading experiment of bovine serum album (BSA) with various concentrations, it was found that the encapsulation efficiency is more than 80%. By the investigation of in vitro release from the BSA-loaded microsphere, it was found that the BSA had a continuous release for more than 6 hours and the release percentage was affected by the initial concentration of the BSA and temperature.

Objective:To investigate the role of TcpC, a virulence factor of uropathogenic Escherichia coli (UPEC), in immune evasion, and analyze its related pathogenic mechanism. Methods:C57BL/6 mice were injected with 10 9 colony-forming unit of wild-type (CFT073 wt) or tcpc gene-knockout (CFT073 Δ tcpc) UPEC CFT073 strains from urethra into bladder to construct a mouse model of pyelonephritis. These mice were sacrificed 5 d after infection and their kidneys were taken to observe the gross pathological changes. Hematoxylin-eosin staining was used to observe histopathological changes in kidney tissues and immunohistochemistry was performed to locate TcpC in kidney tissues. The bacterial loads in urine samples of UPEC infected-mice were counted by ten-fold dilution method, and the presence of tcpc gene in the genomic DNA of bacteria from CFT073-infected mouse kidney or urine samples was measured by PCR. The expression of TcpC at mRNA level was detected by qRT-PCR after infecting dendritic cells with CFT073 wt strains. The influences of UPEC infection on the activation of NF-κB signaling pathway and the secretion of proinflammatory factors by dendritic cells were analyzed by Western blot and ELISA, respectively. The viability of UPEC strains in dendritic cells were observed by laser confocal microscope. Results:Compared with the CFT073 Δ tcpc group, the mice in the CFT073 wt group had obvious abscess in the kidneys as well as massive neutrophil infiltration and abundant TcpC in kidney tissues. The bacterial loads in the urine of CFT073 wt-infected mice were significantly higher than those in the urine of CFT073 Δ tcpc mice. PCR results showed that tcpc gene was successfully amplified from mouse kidney and urine samples. Increased expression of TcpC at both mRNA and protein levels was detected in CFT073 wt-infected dendritic cells. CFT073 wt infection inhibited the phosphorylation of NF-κB p50 and the production of proinflammatory factors in dendritic cells. TcpC promoted the survival of CFT073 wt in dendritic cells. Conclusions:TcpC expression increases significantly during CFT073 wt infection or in mice with CFT073 wt-induced pyelonephritis. It promotes the survival of CFT073 wt in dendritic cells by inhibiting the activation of NF-κB signaling pathway and reducing the secretion of pro-inflammatory cytokines. TcpC is involved in the pathogenesis of UPEC and immune evasion.
