Objective To investigate the effects of 4 °C hypertonic saline (HTS) on S100 protein in serum and brain tissues of rats after cardiac arrest (SCA). Method Thirty SD male rats were randomly divided into shame-operated group (A), NS group (B) ,4℃ NS group (C), HTS group (D) and 4℃. HTS group (E), in e-qual number ( n = 6). Drugs were given to the rats of all groups at the initiation of CPR except group A. The rat model of CA was induced by asphyxia. Over 24 hours after restoration of spontanous circulation ( ROSC), venous blood sample was drawn to detcect the concentration of serum S100 protein in each group, and the rats were sacrificed and their brain tissues were taken for comparing the expressions of S100 protein in hippocampus. One-way analysis of variance and q -test were used for comparison among groups. P < 0.05 was considered significant. Results Compared with group A, the concentration of serum S100 protein in other groups were much higher ( P < 0.01). Compared with group B,the concentrations of serum S100 protein in groups C, D and E were also much lower ( P < 0.01). Compared with groups D and E, the concentration of serum S100 protein in group C was much higher ( P < 0.01). Compared with group D, the concentration of serum S100 protein in group D was higher ( P < 0.05). Compared with group A, the expressions of S100 protein in rats brain tissues of groups B,C and D were much higher ( P < 0.01). The expression of S100 protein in brain tissue of rats in group E was also higher than that in rats of group A ( P < 0.05). Compared with group B, the expressions of S100 protein in brain tissues of rats in groups C,D and E were lower (P < 0.05 and P < 0.01). Compared with group C, the expressions of S100 protein in brain tissues of rats in groups D and E were lower (P < 0.01). Compared with group D, the expression of S100 protein in brain tissue of rats in group E was lower (P < 0.05). Conclusions After CA the 4℃ HTS can decrease serum S100 protein level and inhibit the expression of S100 protein in hippocampus, then protecting the brain tissue.

Objective:To explore the effect of digital rehabilitation system on the recovery of infants with cerebral palsy.Methods:Twenty-one children with cerebral palsy were treated with residual cerebral palsy in Putuo District,and 21 children with cerebral palsy were followed up.The patients were divided into two groups (n =21).The control group was treated by routine OT training by the parents,and the treatment group was treated with the digital rehabilitation system.Three months later,the efficacy was evaluated and compared.Results:After 3 months of treatment,the total effective rate (effective rate and effective rate) of the two groups was 90.5％ and 81％,respectively,and the treatment group was significantly higher than the control group (P ＜0.05).The PROM of the two groups was improved (P ＜0.01),and the PROM in the treatment group was significantly higher than that in the control group (P ＜0.05).FMFM was significantly higher than that before treatment (P ＜0.01),and FMFM was significantly higher in the treatment group than in the control group (P ＜0.01).Conclusion:Family (community) digital rehabilitation system can effectively improve the rehabilitation of children with cerebral palsy.

Objective: To investigate the pathogen spectrum distribution and drug resistance of febrile neutropenic patients with hematological diseases in Shanghai. Methods: A retrospective study was conducted on the clinical isolates from the febrile neutropenic patients hospitalized in the departments of hematology in 12 general hospitals in Shanghai from January 2012 to December 2014. The drug susceptibility test was carried out by Kirby-Bauer method. WHONET 5.6 software was used to analyze pathogenic bacteria and drug susceptibility data. Results: A total of 1 260 clinical isolates were collected from the febrile neutropenic patients. Gram-positive bacteria accounted for 33.3% and Gram-negative bacteria accounted for 66.7%. Klebsiella pneumoniae (12.5%) , Stenotrophomonas maltophilia (9.5%) , Escherichia coli (9.1%) , Pseudomonas aeruginosa (8.7%) , Acinetobacter baumannii (6.6%) , Staphylococcus aureus (5.6%) and Enterococcus faecium (5.0%) were ranked in the first 7 of all pathogens. In the respiratory tract secretions specimens, non-fermented strains accounted for 56.2%. Stenotrophomonas maltophilia accounted for 15.2%. Enterobacteriaceae and coagulase-negative Staphylococci accounted for 42.3% (104/246) and 32.6% (85/246) respectively in blood samples. Enterobacteriaceae and Enterococcus bacteria accounted for 39.4% (76/193) and 28.5% (55/193) respectively in pus specimens. The detection rates of methicillin resistant Staphylococcus aureus (MRSA) and methicillin resistant coagulase negative Staphylococci (MRCNS) were 54.3% and 82.5%, respectively. Staphylococcus bacterial strain was not found to be resistant to linezolid, vancomycin and teicoplanin. The detection rate of Enterococcus vancomycin-resistant strains was 8.9%. Enterococcus was not detected resistance to oxazolidinone strains. Enterobacteriaceae bacteria were highly sensitive to carbapenems. The resistance rate of Pseudomonas aeruginosa to imipenem and meropenem was 34.1% and 15.8%, respectively. Stenotrophomonas maltophilia was more sensitive to minocycline hydrochloride, levofloxacin and sulfamethoxazole. The resistance rate of Acinetobacter baumannii only to cefoperazone-sulbactam was less than 10.0%. The antibiotic resistance rate of Klebsiella pneumoniae, Stenotrophomonas maltophilia, Pseudomonas aeruginosa and Acinetobacter baumanii to most of common antibiotics was lower than that of the CHINET surveillance. Conclusions The pathogenic strain distribution in common infection sites of febrile neutropenic patients was characterized. Bacterial resistance surveillance was better than the CHINET nationwide large sample surveillance in China.

OBJECTIVE: To explore the effects of nano-silicon dioxide( SiO_2) on the survival and poly( ADP-ribose)polymerase-1( PARP-1) expression in human bronchial epithelial cells( 16 HBE cells). METHODS: i) The 16 HBE cells were treated with nano-SiO_2 at concentrations ranging from 0 to 100 mg/L for 24. 0 hours,and CCK-8 assay was used to examine cell viability. ii) The 16 HBE cells were divided into 6 groups: solvent control group( equal volume solvent treatment),micro-SiO_2 control group( treated with 20 mg/L micro-SiO_2),5,10,and 20 mg/L nano-SiO_2 groups( treated with the corresponding final dose of nano-SiO_2),and curcumin group. The curcumin group was given pretreatment with curcumin at a final concentration of 10 μmol/L for 2. 0 hours followed by treatment with a final concentration of 20 mg/L of nano-SiO_2. Cells in each group were harvested at time points of 4. 0,12. 0 and 24. 0 hours after treatment. The relative expression of PARP-1 mRNA and protein in 16 HBE cells was detected by quantitative real-time polymerase chain reaction and Western blotting respectively. RESULTS: i) The survival of 16 HBE cells decreased with increasing nano-SiO_2 treatment dose,showing a dose-effect relationship( P < 0. 01). ii) The expression of PARP-1 mRNA and protein in 16 HBE cells were dose-dependently decreased after nano-SiO_2 stimulation at the 12. 0 and 24. 0 hours time points( P < 0. 01). The expression of PARP-1 mRNA and protein in 5,10,and 20 mg/L nano-SiO_2 groups decreased at the above mentioned time points( P < 0. 05),compared with the solvent control group at the same time points. The expression of PARP-1 mRNA and protein in 20 mg/L nano-SiO_2 group was lower than that in the micro-SiO_2 control group at the same 12. 0 and 24. 0 hours time point( P < 0. 05). The above two indexes of cells were higher in curcumin group than that of 20 mg/L nano-SiO_2 group at the 12. 0 hours time point( P < 0. 05). CONCLUSION: Nano-SiO_2 stimulation can lead to decrease survival of 16 HBE cells in a dose-dependent manner and down-regulation of PARP-1 expression may be one of the mechanisms of proliferation and inhibition of 16 HBE cells induced by nano-SiO_2. Curcumin has certain protective effect on nano-SiO_2-induced 16 HBE cell injury.
