Aim To iuvestigate the effect and the mechanism of salmonmilt DNA (SMD) on age-related involutions in mouse thymus. MethodsFemale BALB/c of 10 months were divided randomly into three groupsaccording to their weights: high dosage group 333.33 mg/(kg @ d), lowdosage group 166. 67 mg/(kg @ d) and control group 0 mg/(kg @ d) .After five weeks, with Image-Pro Plus (version. 4.0) software, the thymusindexes and the thymoctytes in the thymus section were measured, as wellas the thymus cortex thickness. All the data were analyzed by SAS statisticsoftware. Mieroarray technique was applied to screen the gene fragments,which were differently expressed between the high dosage group and thecontrol group, together with RT-PCR to further confirm some of them.Results No significant differences of the variables including bodyweight, thymus weight and thymus indexes among the three groups werefound (F < 3.0 and P > 0.05, respectively). The thymocytes quanti-ties of thymus cortex and medulla in the high dosage group were significantlyhigher than those of the control group [cortex D(H, C) = 9.46, P < 0.01;medulla t( H.C) = 2.53, P < 0.05]. The thymus cortex thicknesses of bothSMD supplement groups were significantly higher than that of the control group[cortex D(L,C)=3.65, P> 0.05; medulla t(L, C)=0.8, P> 0.05] .112differently expressed gene fragments were isolated. Furthermore, we foundthe fragments with the logged number of U23789, X80232 and Aw209102were highly expressed in the high dosage group when RT-PCR techniquewas used. Conclusion SMD may reverse the age-related involutions inmouse thymus via up-regulation the expression of proliferation related genesand development and differentiation related genes simultaneously.

Objective To identify the thromolysis rate in patients with ischemic ccrebrovascular disease in Qingdao area and to analyze the causes of influcncing thrombolytic therapy and investigate their influencing factors. Methods We adopted a unified questionnaire about the status of diagnosis and treatment of stroke in Qigndao. The patients with acute stroke in the 11 departments of neurology of Qingdao municipal and county hospitals (all with thrombolytic conditios) from October 1,2008 to October 31,2009 were collected retrospectively. A face to face questionnaire survey was performed, their clinical data were collected and the factors of influencing thrombolytic therapy were analyzed. Results Actually 864 patients with ischemic eerebrovascular disease were investigated. Only 10 patients received thrombolytic therapy. The thrombolysis rate was 1.16%, and the thrombolysis rate within a 4.5-hour time widow was 6. 33 %. Logistic regression analysis showed that in addition to thrombolytic contraindications,the factors that influencing thrombolytic therapy in patients with acute ischemic stroke included the treatment in different level-hospitals (OR =0.061,95% CI O. 006-0. 703, P =0. 040) and the United States National Institutes of Health Stroke Scale (NIHSS) score (OR = 0.810,95% CI 0. 729-0.900, P = 0.000) at presentation. Conclusions The thrombolysis rate in patients with cerebrovascular disease in Qingdao area was relatively lower. In addition to thrombolytic contraindications, the factors that influencing thrombolytic therapy in ptients with acute ischemic stroke included the treatment in different level-hospitals and NIHSS score at presentation.

Objective To investigate the molecular epidemiology of methicillin-resistant Staphylococcus aureus in China in 2005.Methods From January to December 2005,395 consecutive and non-repetitive isolates of methicillin-resistant Staphylococcus aureus were collected from 17 teaching hospitals in 14 cities.The genotypes of SCCmec were determined by multiplex PCR pulsed-field gel electrophoresis (PFGE)was used to type the chromosome DNA of MRSA.Muhilocus sequence typing(MLST)was used to type the housekeeping genes.Fifty-three strains were selected for MLST typing according to the antimicrobials susceptibility patterns,PFGE types,SCCmec types and the distribution of the regions.The toxin gene was detected by PCR.Results Among 395 isolates of MRSA,SCCmec Ⅲ,untypeable type and type Ⅱ accounted for 61.5%(243/395),24.3%(96/395)and 14.2%(56/395)respectively.In Shenyang,60.7%(17/28)of the isolates were SCCmec Ⅱ,which was significantly higher than other areas. Twenty-four different types and 42 subtypes were found by PFGE typing.Clone A accounted for 50.1%, existing in 13 teaching hospitals in 12 cities and clone R accounted for 23.5%,existing in 9 teaching hospitals in 8 cities.Six sequence types(ST)were found in these isolates with ST239 and ST5 accounting for 75.5% and 17.0% among these isolates,respectively.The prevalence of pvl gene was 2.5% among 395 isolates of MRSA.Conclusions The most types of SCCmec in China were Ⅲ and Ⅱ,and distribution of SCCmec types differed among regions.MRSA outbreaks caused by epidemic multiple-drug resistant clones occurred in big teaching hospitals in China.Meanwhile,the same PFGE pattern may spread among areas. Several international epidemic MRSA clones may exist in China.
