Objective To analyze the risk factors of subclavian venous catheter-related infections in patients with traumatic hemorrhagic shock (THS) and provide a basis for prevention and control of the infection. Methods A retrospective study was conducted. 357 patients with THS and indwelling of subclavian vein catheter admitted in the Department of Emergency of Affiliated Hospital of Sichuan Provincial Luzhou Medical College were enrolled, and according to the infection state, they were divided into infection group (56 cases) and non-infection group (301 cases). The patients' data of gender, age, history of underlying disease, catheter position, catheter indwelling time, time staying in hospital, situation of antimicrobial drug used, application of tracheotomy or not, white blood cell count (WBC) levels, etc were collected for univariate analysis. The resulting indexes with statistical significance were applied for carrying out the multivariate logistic regression analysis, and then the independent risk factors involved in the development of subclavian venous catheter-related infections in the shock patients could be screened out.Results In 357 patients with THS, 56 were infected (15.7%). Univariate analysis showed: age ≥ 60 years (χ2 = 19.839,P < 0.001), with diabetes mellitus in past history (χ2 = 6.252,P = 0.012), catheter indwelling time ≥ 7 days (χ2 = 19.261,P < 0.001), time staying in hospital ≥ 7 days (χ2 = 4.315,P = 0.038), time for use of antimicrobial drug≥ 7 days (χ2 = 16.161,P < 0.001), tracheotomy (χ2 = 40.969,P < 0.001), WBC < 4×109/L (χ2 = 39.451,P < 0.001) and the disease severity grade 4 - 5 (χ2 = 8.345,P = 0.004) were the risk factors of subclavian venous catheter-related infections in patients with THS. Multivariate analysis showed: catheter indwelling time ≥ 7 day [odds ratio (OR) = 16.713, 95% confidence interval (95%CI) 3.651 - 76.624), tracheotomy (OR = 6.861, 95%CI 2.377 - 18.246), WBC < 4×109/L (OR = 4.903, 95%CI 1.887 - 12.643) were the independent risk factors of subclavian venous catheter-related infections in THS patients.Conclusion The strict implementation of aseptic catheterization, shortening the time of catheter indwelling as much as possible and the rational use of antibiotics can effectively reduce and prevent the incidence of venous catheter-related infection in THS patients.

Objective To investigate the expressions of receptor for advanced glycation endproducts (RAGE) and nuclear factor κB(NF-κB) in brain hippocampus of rat with chronic fluorosis,and to reveal the mechanism of brain damage resulted from chronic fluorosis.Methods Sixty clean grade SD rats were randomly divided to three groups(20 rats in each group,10 female and 10 male) fed with different contents of fluoride,control group with normal tap-water(＜ 0.5 mg/L fluoride),small dosage of fluoride exposure group(10 mg/L fluoride in tap-water) and large dosage of fluoride exposure group(50 mg/L fluoride) for six months.Then the rats were killed by femoral artery bleeding and hippocampus was removed.Protein and mRNA levels of RAGE and NF-κB in the hippocampus were determined by Western blotting and quantitative real time PCR,respectively.Results As compared to the control groups[(100.00 ± 2.60)％,(100.00 ± 7.80)％],the expressions of RAGE and NF-κB at protein level in the hippocampus were significantly increased in the small dosage of fluoride exposure groups [(205.00 ± 15.30)％,(156.00 ± 12.20)％] and the large dosage of fluoride exposure groups[(232.00 ± 10.90)％,(162.00 ± 9.80)％,all P ＜ 0.05]; for the mRNA level of RAGE and NF-κB,the expressions were higher in the small dosage of fluoride exposure groups(1.27 ± 0.09,0.83 ± 0.15) and the large dosage of fluoride exposure groups (2.60 ± 0.19,1.27 ± 0.19) than those of the control groups(0.66 ± 0.18,0.32 ± 0.08,all P＜ 0.05).Conclusions The increased expressions of RAGE and NF-κB in the hippocampus of rat brain are caused by chronic fluorosis,and these changes may be associated with the mechanism of nerve injury.

Objective Aim of the study is to investigate the expression of syndecan-4 and nuclear factor κB(NF-κB) in the kidney of rat with chronic fluorosis,and to reveal the mechanism of kidney damage resulted from the toxicity of excessive amount of fluoride.Methods According to body mass and sex,sixty SD rats were randomly divided to three groups according to body mass and fed with different contents of fluoride:control group with normal tap-water(＜ 0.5 mg/L fluoride),small dosage of fluoride exposure group (adding 10 mg/L fluoride in tap-water) and large dosage of fluoride exposure group (50 mg/L fluoride) for six months.The protein level of syndecan-4 and NF-κB in the kidney was detected by Western blotting and syndecan-4 mRNA level by quantitative real time PCR.Results As compared to the control group[(100.0 + 8.1)％],the expression of syndecan-4 at protein level in the kidney of rat was significantly increased in the small dosage of fluoride exposure group [(198.5 + 5.6)％,P ＜ 0.05] and large dosage of fluoride exposure group [(209.2 + 13.0)％,P ＜ 0.05]; the protein levels of NF-κB in the small dosage of fluoride exposure group[(284.4 + 11.1)％,P ＜ 0.05] and in the large dosage of fluoride exposure group[(343.2 + 2.9)％,P ＜ 0.05] were significantly increased than that of the control group[(100.0 ± 10.7)％].The mRNA levels of syndecan-4 in the kidney in the small dosage of fluoride exposure group and large dosage of fluoride exposure group(0.431 + 0.058 and 0.453 ± 0.065,both P ＜ 0.05,respectively) were significantly increased than that of the control(0.128 + 0.026).Conclusions The increased expression of NF-κB in the kidney is induced by increased expression of syndecan-4,which may be involved in kidney damage of chronic fluorosis.
