Objective To analyze the distribution characteristics and antimicrobial resistance of isolated Acinetobacter(A.)bau-mannii from the clinical inpatients in our hospital from 2008 to 2013 to provide the basis for rational use of antibacterial drugs in clinic.Methods The BD phoenix-100 fully automatic microbial analyzer(USA)was adopted to conduct the strain identification and the minimal inhibitory concentration(MIC)detection of clinically isolated A.baumannii.All obtained data were analyzed.Results 128,173,350,282,186 strains of A.baumannii in turn were isolated during these years,the strains in sampling from the clinically i-solated A.baumannii during 2012 was mainly originated from the sputum samples(155 strains,68.28%).In the distribution of hos-pital departments,most concentrated in ICU(65 strains,28.63%),followed by the respiratory department(47 strains,20.70%),the emergency observation wards(35 strains,15.42%)and the apoplexy and geriatric wards(24 strains,10.57%),the most of patients were older people aged more than 60 years.And according to the data within these 5 years,many kinds of different antibacterial drugs had generally the increased drug resistance rate,especially the increasing trend during 2011-2012 was more obvious,the pen-icillins all showed extensive drug-resistance.In the third,fourth generation cephalosporins,aminoglycosides and quinolones were generally drug-resistant.The drug resistance rate of cephalosporins(ceftazidime,cefotaxime,cefepime)remained at a higher level of 75.00%-85.00%.The drug resistance rate of quinolones(ciprofloxacin,levofloxacin)and aminoglycosides(gentamicin,amikacin) also showed the increasing trend year after year.The drug-resistant rate of the beta lactam compound preparations had the rapidly increasing speed,such as which of ampicillin /sulbactam was increased from 60.16% to 83.33%,which of carbapenems such as imipenem and meropenem was increased more significantly,the drug-resistant rate of imipenem was increased from 25.20% to 82.27%,and the detection rate was continually increased.And the drug resistant rate of Schupson was increased from 18.89% to 80%,but the only difference was the drug named Colistin(polymyxin E)maintained a low drug resistance rate during these five years.Conclusion Resistance of A.baumannii to various antibacterial drugs is gradually increased and the isolation rate of multi-drug-resistant and pan-drug resistant A.baumannii is increased year by year.So A.baumannii infection and its drug-resistance changes should be vigilant and be paid more attention to for preventing the emergence and spread of drug-resistant A.baumannii strains.

Hepatocellular carcinoma (HCC) is one of the most common causes of cancer-related death in the world, and only 20% of HCC patients can undergo radical treatment.Radiofrequency ablation induces coagulative necrosis of cells via thermal energy, kills tumor cells, and makes it possible to cure HCC.Many clinical studies have confirmed that radiofrequency ablation provides good local control and has high safety, and therefore, it can be used to replace radical surgery.This article reviews the indications and therapeutic effect of radiofrequency ablation in the treatment of HCC, as well as its comparison with radical surgical resection and transarterial chemoembolization in terms of their therapeutic effects.It is pointed out that the treatment regimen should be selected based on the patient′s individualized conditions.

This study was aimed to explain the relationship between chemical component and therapy objective and to identify effective component group (ECG). The objective of this study is to build a new method to identify the ECG. Traditional Chinese medicine (TCM) formula and one of its treated diseases were selected as the re-search object. The entity grammar systems (EGS) were used as the theoretical framework. A grammatical method for ECG identification was constructed. The component-disease relationship was inferred and the ECG was identi-fied with these inference results. In this paper, 16 compounds which act to 12 proteins in Type 1 diabetes melli-tus (T1D) disease network were identified from Bai-Hu Tang plus Xiao-Ke Fang and 9 chemical compounds were determined as the candidate effective components group. The results indicated that this method can be used to identify ECG and provide a new way to elucidate the molecular mechanism of TCM formula.

Objective To investigate the protective effect of sodium butyrate on brain injury induced by pneumolysin of infantile rats.Methods Ninety-six normal healthy 1-month-old Spragne-Dawley (SD) rats were randomly divided into three groups,including pneumolysin (PLY) group (n =32),in which rat was injected PLY via external carotid; Normal saline (NS) group (n =32),injected NS via external carotid; sodium butyrate (SB) group (n =32),after injecting PLY,immediately administrated SB via venous.In the injection the 24th h and 48th h,superior vena cava blood was taken,and the animals were sacrificed,and brain tissue samples were prepared.The brain water content (BWC) was recorded by measuring both wet and dry weight,the Evans blue (EB) level was measured by the formamide method.The serum levels of high mobility group protein B1 (HMGB1) and nuclear factor kappa B (NF-κB) were measured by enzyme-linked immunosorbent assay (ELISA).Results In PLY group,brain tissue BWC,EB level,and the blood level of HMGB1 and NF-κB were increased significantly compared with the NS group at each time point,the difference was statistically significant (P ＜ 0.05).These indices were lower in the SB group compared with PLY group,the difference was statistically significant (P ＜ 0.05).The positive correlation was gotten between HMGB1 and NF-κB,BWC,EB levels in the PLY group and SB group (r =0.817 ～0.917,P ＜ 0.05).Conclusions SB has neuroprotective effect in brain injury induced by PLY,which maybe relevant to inhibition of NF-κB activation and suppression of HMGB1 expression.

Objective To investigate the change of serum HMGB1 level and its clinical significance in children with sepsis.Methods Serum HMGB1 and procalcitonin (PCT) levels were determined in 30 healthy individuals and 46 children with sepsis,and the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scoring system was evaluated in children with sepsis.These indexes were also collected on the third and fifth days.The correlations between serum HMGB1 level and serum PCT level as well as APACHE Ⅱ score were analyzed.Results Serum HMGB1 levels in children with sepsis on the first day,the third day and the fifth day were significantly higher than those in control group,these differences were statistically significant [(26.28 ± 1.54) ng/ml,(20.32 ± 1.29) ng/ml,(12.84 ± 1.06) ng/ml vs (1.52 ± 0.29) ng/ml,P ＜0.05],HMGB1 levels among three time points were also significantly different(P ＜0.05).The serum HMGB 1 levels were positively correlated with the PCT levels (r =0.931,P ＜ 0.05) and APACHE Ⅱ score (r =0.915,P ＜ 0.05).Conclusion Serum HMGB1 level is obviously elevated in children with sepsis,and the level of HMGB1 can reflect the severity of sepsis.

This study examined the effect of MMP9 gene on the biological behaviors of trophoblasts and explore the relation between MMP9 gene and the "superficial implantation of placenta". In vitro cultured trophoblasts (TEV-1 cells) were transfected with synthesized double-stranded MMP9 RNA (siRNA) by using lipofectamine2000™ technique and the expressions of MMP9 mRNA and protein and the growth and invasiveness of the TEV-1 cells were determined. Our results showed that siRNA transfection could significantly inhibit the expression of MMP9 gene in the TEV-1 cells and the growth and invasiveness of the TEV-1 cells transfected RNA was significantly reduced (P<0.01). We are led to conclude that silencing of MMP9 gene with siRNA can inhibit the growth and invasiveness of trophoblasts and increasing the expression of MMP9 might help prevent and treat preeclampsia.
