With rapid ageing population,the extensive application of mechanical ventilation and development of organ transplantation,infection caused by gram-negative (G-) bacilli,which have become the common pathogens causing nosocomial (especially ICU) infection,has increased and accounted for more than 65% of the hospital acquired infections.Severe infections in intensive care units are usually caused by Pseudomonas aeruginosa,Acinetobacter sp.,Enterobacteriaceae bacteria and Stenotrophomonas maltophilia,presenting challenges to the treatment.In addition,drug-resistant G-bacilli strains have increased year by year,accompanying with appearance of muti-drug resistant and pan-resistant strains of Pseudomonas aeruginosa and Acinetobacter baumannii.Several pathways may lead to drug resistance of G-bacilli,including permeability changes in ectal membrane,reformation of penicillin-binding protein,enhancement in level of pump MexAB-OprM,overproduction of antibiotic modification enzymes such as cephalosporinase,new type of beta-lactamases especially extended-spectrum beta-lactamases (ESBLs),AmpC beta-lactamase and Klebsiella pneumoniae carbapenemase (KPC).Clinical work is facing the challenges caused by drug resistance of G-bacilli,so the isolation and cultivation of pathogenic bacteria,drug sensitivity test in vitro,monitoring of drug resistance and researches on resistant mechanism should be enhanced,and proper antibiotics should be selected for treatment of G-bacilli infection.Polymyxin is recommended,if necessary,for treatment of multi-and pan-resistance G-bacilli infection,meanwhile the adverse effects of polymyxin treatment should be closely monitored.

Objective To evaluate CT features and diagnostic value of fungus infection of paranasal sinuses. Methods CT findings in 16 patients with fungus infection of paranasal sinuses proved surgically and pathologically were analyzed.Results CT findings of fungus infection of paranasal sinuses included: unilateral involved, maxillary sinus was mainly affected or other paranasal sinuses involved simaltaneously, the soft tissue within paranasal sinuses presented as hyperplasia of nodule and polyp-like, and there were some punctuated and tubercular calcification inside .Sinus cavity enlarged and the bone wall was destroyed in some cases. Conclusion CT manifestations of fungus infection of paranasal sinuses are of characteristics, CT scan is of important value in diagnosing this disease.

On the basis of summarizing the general situation of current internal and external network construction of hospitals,the paper introduces the main hidden dangers of hospital network security,puts forward internal and external network security management measures,and elaborates the internal and external network security construction principle,network topology structure,and network construction achievements of the First Affiliated Hospital of Guangxi Medical University.

Virtual Reality is just emerging as an accepted scientific discipline. It has been widely used in medicine. The major applications of virtual reality for medicine are introduced from three areas :virtual humans,the fusion of virtual humans with real humans and virtual telemedicine. The advanced graphics behind medical virtual reality,such as computational demands,hardware and software environments is briefly discussed. This article also gives a summary of existing distributed VR systems.

MiR-200 family is a cluster of miRNAs closely linked to EMT. The miR-200 family contains miR-200a, miR-200b, miR-200c, miR-141 and miR-429. Many studies have shown that miR-200 family are key regulators of EMT and determine the epithelial phenotype. They are important to both EMT development and tumor progression. This paper reviews the advancement in the research of miR-200 family and its mechanism.

This article summarized literatures in the recent ten years on the mechanisms of Ci-xue therapy from such aspects as hemorheology, vascular biology, blood constituents and blood coagulating system.

Objective To investigate the inhibitory effects of recombinant T-bet adenovirus (AdT-bet) on airway inflammation in mice with asthma, and to explore the relevant mechanisms. Methods C57BL/6 mice were randomly allocated into 4 groups with 12 mice each. The asthmatic model was reproduced in group A, B and C by administration of ovalbumin (OVA) in aluminum hydroxide. Mice in group A, B and C received 50?l AdT-bet (108pfu) and AdLacZ and PBS, respectively, 19 days prior to OVA challenge. Bronchoalveolar lavage fluid (BALF) was collected on the 26th day after the induction of asthma for the determination of the cellular composition and concentrations of IL-4, IL-5 and IFN ?. Meanwhile, IgE content in serum was determined. The pathological changes and the expression of GATA-3 in the lungs of these mice were investigated. Results The percentage of eosinophils (EOS) and concentrations of IL-4 and IL-5 in BALF of group A were 0.6%?0.2%, 6.8?3.7pg/ml, 12.5?4.8pg/ml, respectively, which were significantly lower than those in group B (20.9%?6.8%, 92.4?23.0pg/ml, 56.5?11.8pg/ml) and group C (20.8%?6.7%, 90.4?22.8pg/ml, 57.3?12.2pg/ml, P

Objective To investigate the significance of antifilaggrin autoantibodies (AFA) in rheumatoid arthritis (RA).Methods Filaggrin was extracted from the skin of the patients who had breast cancer undergoing mammectomy.AFA were detected at the sera titer 1∶10 with Western blotting,and its clinical significance was investigated with the corresponding clinical materials.Results Antifilaggrin autoantibodies (AFA) were detected in 39 9%(71/178) of RA patients,and 6 cases of control group,with a specificity of 0 969.AFA were present in 48 4%(15/31) of the early and 29 2% of seronegative RA.AFA positive patients exhibited higher frequency of Sjgren′s syndrome;The average and onset ages of AFA positive patients were older than those of the negative ones,and there was correlation between AFA and age.The frequency and average titer of RF patients were higher in AFA positive than in negative ones.AFA was significantly correlated to RF,AKA and APF.Conclusion AFA are valuable diagnostic parameter for RA,especially in the early and seronegative RA.AFA is significantly correlated to AKA and APF,but they are not totally overlapped,None of the three antigens used bear all the epitopes recognised by antifilaggrin autoantibodies.Immunoblot detection of AFA,a simple and reliable test,may be complement to conventional IIF detection of AKA and APF.
