Objective To investigate the expression and significances of DPP-4 and IL-6 in febrile seizures(FS).Methods FS were induced in Sprague-Dawley(SD) rats at P14 in a hot water bath by using classical model of hyperthermia-induced seizures.A genome-wide microarray experiment was generated in the rats.The relationship between the differentially expressed genes were analyzed by the method of bioinformatics, and the gene and protein levels of DPP-4 and IL-6 were detected by QPCR,WB and ELISA.Selected 50 children with FS(FS group) and 25 healthy children(control group), and to compare the gene and protein levels of DPP-4 and IL-6 between the two groups.Results Interaction network diagram of differential gene expression showed that there may be interactions between DPP-4 and IL-6.Animal and clinical experiments showed that the DPP-4 and IL-6 gene and protein levels were significantly higher in FS group compared with control group(P<0.05).Conclusion There were high gene and protein expressions of DPP-4 and IL-6 in the FS group compared with the control group.These results indicated that immune and inflammations may play an important role in the FS, and it has provided an attractive pharmacological target for the treatment of FS in clinic.

In this paper, a detailed analysis was made on relevant literatures about bear bile powder in terms of chemical component, pharmacological effect and clinical efficacy, indicating bear bile powder's significant pharmacological effects and clinical application in treating various diseases. Due to the complex composition, bear bile powder is relatively toxic. Therefore, efforts shall be made to study bear bile powder's pharmacological effects, clinical application, chemical composition and toxic side-effects, with the aim to provide a scientific basis for widespread reasonable clinical application of bear bile powder.

AIM: This study was designed to explore the differentially expressed genes between hypobaric hypoxic delayed preconditioning (HHDP) and normal mouse hippocampus. METHODS: HHDP was produced by treating the animals at a 7 000 m high altitude for 2.5 h/d for 3 d. At 36 h after last time decompression, total RNA was isolated from hippocampus. cDNA was synthesized and amplified by SMART PCR. cDNA libraries of differentially expressed gene between HHDP and control hippocampus were constructed. 452 clones from forward (subtracted control from preconditioning) cDNA library and 74 clones from backward (subtracted preconditioning from control) one were screened by reverse Northern hybridization. RESULTS: Screening with subtracted probes, hybridization signal of 85 gene fractions decreased and that of 217 gene fractions increased by more than 2 times in HHDP hippocampus compared with control. Screening with unsubtracted probe, hybridization signal of 44 gene fractions decreased and that of 135 gene fractions increased by more than 2 times in HHDP hippocampus compared with control. Some of the clones had been sequenced. Analysis and comparison with the data of GenBank were performed. The results showed that mouse cytochrome C oxidase subunit 1, NADH dehydrogenase subunit 1 and 6, deleted in split-hand/split-foot 1 region (DSS1) and cDNA corresponding to clone IMAGE: 5251089 of mice cDNA library were increased in hippocampus of HHDP mice. cDNA corresponding to clone IMAGE: 3593193, mus musculus adult male olfactory brain cDNA and mus musculus bladder RCB-0544 MBT-2 cDAN were decreased in hippocampus of HHDP mice. CONCLUSION: Many genes expresses differentially in hippocampus of mice during HHDP. This may be one of the molecular mechanisms of HHDP.

Objective To investigate the distribution and drug resistance of bacterial pathogens isolated from orthopedic wounds.Methods Data of bacterial strains isolated trom orthopedic wounds in the Third Hospital of Hebei Medical University from January 2008 to December 2012 were retrospectively analyzed.Strains were identified by using French bioMérieux Vitek32 identification system,and the drug susceptibility was tested by Kirby-Bauer method.Chi-square test for linear trend was performed to reveal the changes of distribution and drug resistance of the strains.Results A total of 2 456 bacterial strains were isolated,vith 1 652 (67.26%) gram-negative bacilli,777 (31.64%) gram-positive cocci,26 (1.06%) fungi,and 1 (0.04%) gram-positive bacillus.The top five pathogens were Staphylococcus aureus (666 strains,27.12%),Pseudomonas aeruginosa (606 strains,24.67%),Acinetobacter baumannii (355 strains,14.45%),Escherichia coli(188 strains,7.65%) and Enterobacter cloacae (187 strains,7.61%).The positive rate of Acinetobacter baumannii was on the rise during 2008 and 2012 (x2 =35.266,P < 0.0l).The rates of pan-drug resistant strains in Acinetobacter baumannii and Pseudomonas aeruginosa were 6.20% (22/355) and 0.17% (1/606),respectively.The rates of extended-spectrum β-lactamases positive strains in Escherichia coli and Klebsiella pneumoniae were 39.89% (75/188) and 29.23% (19/65),respectively.The rates of methicillin-resistant strains in Staphylococcus aureus and coagulasenegative Staphylococcus were 40.69% (271/666) and 52.38% (22/42),respectively.The rate of vancomycin-intermediate strains in Enterococci was 3.70% (2/54).The positive rate of methicillin-resistant &aphylococcus aureus was on the rise during 2008 and 2012 (x2 =18.317,P < 0.01).Staphylococcus aureus were sensitive to teicoplanin,vancomycin and linezolid; Resistance rates to rifampicin and amikacin were 11.29%-33.33%; Resistance rates to penicillins and erythromycin were 76.80%-100.00%; Resistance rates to cefazolin,cefuroxime,cefoxitin,amikacin and levofloxacin were on the rise (P < 0.05) ; And resistance rates to sulfamethoxazole (28.11%-48.35%) were on the decline in the same period (P < 0.01).Resistance rates of Pseudomonas aeruginosa to imipenem,meropenem and sulfamethoxazole were on the rise (P < 0.05) ; Resistance rates to ciprofloxacin,levofloxacin,amikacin,gentamicin and piperacillin/ tazobactam were on the decline (P < 0.05) ; Resistance rates to cefoperazone/sulbactam were the lowest (9.15%-20.51%).Resistance rates of Acinetobacter baumannii to imipenem,meropenem,levofloxacin,piperacillin/tazobactam,sulfamethoxazole were on the rise (P < 0.01); Resistance rates to cefoperazone/ sulbactam were the lowest (11.86%-19.70%).Escherichia coli and Enterobacter cloacae were sensitive to imipenem and meropenem,and the resistance rates to cefoperazone/sulbactam and piperacillin/tazobactam were low (0-14.29%); Resistance rates of Escherichia coli to piperacillin,cefepime,amikacin,levofloxacin,cefoperazone/sulbactam were on the decline (P < 0.05) ; Resistance rates of Enterobacter cloacae to cefoxitin were on the rise (P < 0.01),while the resistance rates to piperacillin,ceftazidime,cefoperazone,ceftriaxone,levofloxacin were on the decline (P < 0.05).Conclusion During 2008 and 2012,the predominant bacterial pathogens of orthopedic wound in patients of the Third Hospital of Hebei Medical University are Staphylococcus aureus,Pseudomonas aeruginosa,Acinetobacter baumannii,Escherichia coli and Enterobacter cloacae,and most strains are multiple drug resistant.
