Objective To find out the potential risk factor of plague in Wanzhou section of the Three Gorges Reservoir area, and to provide scientific basis for prevention and control of plague. Methods Rodents were captured by rat traps/cages at night and identified into species in Wanzhou section of the Three Gorges Reservoir area from 2001 to 2009. Flea was counted and serum antibodies against plague F1 of rats, cats and dogs were detected by indirect hemagglutination (IHA). Plague surveillances were performed in human beings and rats. Results The rodents captured belonged to 9 species, 2 families, 2 orders and 1 classes. The average indoor rodent density was 1.16% (961/82 558), and was 1.12% (1345/119 671) outdoors. Rattus norvegicus was the dominant species,accounting for 50.37%. The proportion of R. Flavipectus was 3.80% in 2004, 4.50% in 2008 and 10.12% in 2009,showing an increasing trend year by year. There were three kinds of mice infected fleas in Wanzhou, which including Xenopsylla cheopis, Leptopsylla segnis and Ctenocephalides felis. The average rate of flea infected mice was 1.18%(82/6959) and the total flea index was 0.036. No F1 antibody against plague was detected in 6959 dogs and 160 cats serum samples. Conclusions No plague is found in Wanzhou section of the Three Gorges Reservoir area. But R.Flavipectus, Xenopsylla cheopis and Leptopsylla segnis are dominant species in Wanzhou section, and the proportion of which shows an increasing trends year by year. There is a potential risk of plague outbreaks in Wanzhou section of the Three Gorges Reservoir area.

Transient forebrain ischemia-reperfusion(I/R);Brain-derived neurotrophic factor(BDNF);Histone deacetylase 3(HDAC3);Hippocampus Objective To evaluate the effect of transient forebrain ischemia-reperfusion(I/R)on the binding of brainderived neurotrophic factor(BDNF)promoters to histone deacetylase 3(HDAC3)in the hippocampus of rat and investigate its mechanism.Methods The I/R model of SD rats(I/R group)was established by Pulsinelli four-vessel clamping method,and sham operation group(Sham group)was set at the same time,which were observed for the survival of neurons in the hippocampus of rats by Nissl staining,detected for the binding of BDNF promoters(Bdnf-p1,Bdnf-p2,Bdnf-p4 and Bdnf-p6)to HDAC3 by chromatin immunoprecipitation(ChIP)and determined for the expression of brain derived neurotrophic factor antisense(BDNF-AS)by qPCR.Results Compared with Sham group,the quantity of neurons in hippocampal CA1 region of rats decreased significantly in I/R group,while those in CA3 region and DG region showed no significant changes.The binding levels of Bdnf-p1 and Bdnf-p2 to HDAC3 in hippocampal CA1 region decreased significantly in I/R Group(t = 2.575 and 2.241 respectively,each P<0.05),while there was no significant difference in the binding levels of Bdnf-p4 and Bdnf-p6 to HDAC3(t = 1.033 and 0.348 respectively,each P>0.05);The binding levels of Bdnf-p1 and Bdnf-p2 to HDAC3 in CA3 region increased significantly(t = 12.600 and 3.191,P<0.001 and<0.05,respectively),while the binding level of Bdnf-p6 to HDAC3 decreased significantly(t = 4.029,P<0.05)and no significant difference was observed in the binding level of Bdnf-p4 to HDAC3(t = 0.175,P>0.05);In DG region,the binding level of each BDNF promoter to HDAC3 showed no significantly difference(t = 0.630 ～ 1.687,each P>0.05).Meanwhile,the expression level of BDNF-AS in hippocampal CA1 region of rats decreased significantly(t = 2.560,P<0.05),but increased significantly in hippocampal CA3 and DG regions(t = 3.543 and 3.637 respectively,each P<0.01)in I/R group.Conclusion I/R showed a significant effect on the binding level of BDNF promoter to HDAC3 in rat hippocampus,which may play a role by changing the expression level of BDNF-AS.

Objective To study the clinical features and to improve the treatment on the elderly patients with brain tumor.Methods Retrospective analysis of 163 cases with brain tumor which had been confirmed by CT,MRA or pathology.Results Of all the 163 cases,121 were located in supratentorium,most of which were meningiomas and gliomas.Most patients(129 cases)had comorbidity.After operation,symptoms disappeared or obviously improved in 126 cases,moderately improved in 19 cases,and did not changed in 6 patients.Twelve cases died after operation in a month, in which 9 patients were over 75 years old.The death rate of operation was 6.1%.Conclusions It is important to know the atypical manifestation of brain tumor in the elderly,which may prevent clinical misdiagnosis and mistherapy.The perioperative management is indispensable to the prognosis of the patients.The choice of operation and medication should be in individualized.

Objective To investigate the expression of the interleukin-1 receptor(IL-1R)Ⅰ,IL-1RⅡand IL-1R accessory protein(IL-1RAcP)in osteoarthritis and analyse their biological significance.Methods Immunohistochemistry and reverse transcription-polymerase chain raction(RT-PCR)were adopted to detect the expression of IL-1RⅠ,IL-1RⅡand IL-1RAcP on the synovium of 107 OA patients.Results Immunohis- tochemistry showed strong positive expression of IL-1RⅠand IL-1RAcP,and positive expression of IL-1RⅡ. The expression was distributed in lining cells,monocyts and vascular endothelial cells of the sublining area, but all of them were negative or weak positive in normal synoviums.RT-PCR showed the expression of IL-1RⅠ,IL-1RⅡand IL-1RAcP in OA synoviums was significantly enhanced than normal synoviums (P＜0.05),and the expression of IL-1RⅠwas significantly enhanced than IL-1RⅡ(P＜0.05),but no sig- nificant difference with IL-1RAcP(P＞0.05).In stageⅡandⅢOA synoviums,the expression of IL-1RⅠand IL-1 RAcP had no significant difference with normal synoviums(P＞0.05).The expression of IL-1RⅡin stageⅢOA synoviums was significantly enhanced than normal(P＜0.05).Conclusion IL-1RⅠ,IL-1RⅡand IL-1RAcP play significant roles in the pathogenesis of OA,especially IL-1RⅠand IL-1RAcP.But their increase is only observed in the early stage of OA.These suggest that they may have no association with the development of OA and have no direct association with the severity of OA.OA can be cured by interrupting the signal transduction path in which IL-1 has played biological roles.

OBJECTIVETo study the clinical distribution characteristics and vicissitude of antibiotic resistance of Acinetobacter baumannii (AB), and to look for the risk factors of AB infection in order to provide reasonable reference for the prevention and treatment of its infection.

METHODSSpecimens of blood, venous catheters, sputum, wound exudates and pharyngeal swabs from 156 patients hospitalized in our burn ICU from January 2006 to December 2008 were collected and cultured. The clinical distribution and antibiotic resistance of AB were determined and analyzed. The risk factors related to AB infection were analyzed. Drug resistance rate data were processed with WHONET 5.3 software; the other data were processed with chi-square test and Logistic regression analysis.

RESULTSNinety-two strains of AB were identified during the three years from different kinds of specimens, with 41 (44.6%) from wound exudates, 14 (15.2%) from pharyngeal swabs and sputum respectively, 13 (14.1%) from blood, and 10 (10.9%) from venous catheters. AB accounted for 23.1% (30/130), 27.5% (25/91), 28.2% (37/131) respectively among the strains detected in 2006, 2007, and 2008. During the three years, except for imipenem and cefoperazone/sulbactam, the average resistance rates of AB to other ten commonly used antibiotics were all above 50.0%. Burn area (χ(2) = 24.374, P = 0.000), mechanical ventilation (χ(2) = 8.968, P = 0.003), duration of use of antibiotics (χ(2) = 3.981, P = 0.046), and deep venous catheterization (χ(2) = 9.170, P = 0.002) were the risk factors of AB infection, and the former two were independent risk factors.

CONCLUSIONSThere is a pan-drug resistance tendency of AB in our burn ICU, and the positive culture rates are increasing in recent years. Disinfection and isolation measures, appropriate use of antibiotics, avoidance of invasive performances such as deep venous catheterization and tracheostomy, or shortening their duration are important means to prevent and control infection of AB.
