To investigate the changes of drug resistance of pseudomonas aeruginosa ( PA) to common antimicrobial agents in recent 3 years in Anhui province. The average drug resistance rate was 15. 3%, 17. 0% for piperacillin/tazobactam, amikacin respectively, while the average resistance rate was higher for the third generation cephalospo-rin cefotaxime, ceftriaxone and ceftizoxime, which was between 42. 0% and 55. 0%. The average drug resistance rate was 25. 2% for imipenem. The resistance rates for ceftazidime, cefepime, ceftriaxone and ceftizoxime were sig-nificantly increased( P<0. 05 ) . The resistance of PA to the third generation cephalosporin and ciprofloxacin in-creased gradually, close attention should be paid to it in clinical practice.

Objective:To explore the therapeutic effect,security and influencing factors of methylphenidate titration program,try to find the potential predicting index of therapeutic effect.Methods:This study was openly designed.The patients who were fit for DSM-Ⅳ diagnosis criteria of attention deficit hyperactivity disorder(ADHD) underwent systematic methylphenidate titration treatment until they attained the most optimal dose with best therapeutic effect and minimal side effects.The primary evaluative index of therapeutic effect was ADHD rating scale filled by teachers(ADHD-RS-Ⅳ),and secondary index included abbreviated Conners questionnaire filled by teachers,ADHD rating scale and Conners questionnaire filled by parents.The matching sample t analyses were used,then the differences of rating scale between pre and post treatment were compared.The potential influencing factors information of therapeutic effects including symptom severity degree when visiting,IQ,sensory integration capability and achievement of school etc.were collected.Finally,the correlation analysis was used for continuous variables andvariance analysis for dichotomization variables to analyze and check the factors' influence of declining scores of behavior scale.Results:The final prescribed daily dose for patients who completed dose titration was(17.3?7.7) mg on average,computed by kilo bodyweight was(0.45?0.11) mg/(kg?d).All the scale scores between pre and post treatment were significantly different(the pre-treatment score of ADHD rating scale completed by teachers was 30.25?9.16,and post-treatment score were 19.87?10.03,P

OBJECTIVE To investigate the trend of resistance to antimicrobial agents among clinical isolates of Escherichia coli and Klebsiella pneumoniae in 2006-2007.METHODS Agar diffusion test was used to analyze the changes in drug susceptibility of E.coli and K.pneumoniae from 30 hospitals in Anhui in 2006-2007.The resistant rate,intermediate rate and susceptibility rate of drugs were calculated according to the criteria in guidelines of CLSI(2007).RESULTS Carbapenems were the most active antimicrobial agents tested against E.coli and K.pneumoniae.Cefepime,ceftazidime,piperacillin/tazobactam and amikacin showed excellent activity against E.coli and K.pneumoniae.E.coli and K.pneumoniae were still resistant to cefuroxime,ceftriaxone,cefotaxime and aztreonam.ESBLs-producing E.coli strains accounted for 48.9% in the year of 2006 and for 47.2% in the year of 2007.ESBLs-producing K.pneumoniae strains accounted for 36.6% in the year of 2006 and for 40.0% in the year of 2007.CONCLUSIONS Imipenem remains highly active against E.coli and K.pneumoniae.

OBJECTIVE:To establish the method to determine the concentration of human plasma felodipine by HPLC-MS.METHODS:The HPLC separating system was adopted and the mobile phase was a mixture of methanol-water-acetic acid with a flow rate at1ml/min and split ratio at2∶1,the fixed phase was Hypersil C 18 column;The mass spectrometric de-tection system and AP-ESI positive ion model were adopted with the atmosperic pressure at0.054Pa(400psi),the protecting gas at N 2 10L/min,capillary voltage at4000V,the ion source temperature at100℃and the fragment voltage at220V,the ions collected by SIM were felodipine m/z411(M+Na),Nimodipine m/z441(M+Na).RESULTS:The linear concentration range for felodipine was0.2～50ng/ml with a minimum detection limit at0.15ng/ml,the recovery was above90.93%with both the intra-day RSD and the inter-day RSD at less than9.8%(RSD

ObjectiveTo investigate the characteristics of sexual behavior and HIV infections between normal men who have sex with men (MSM) and money boy (MB) in Jining city,so as to provide the basis for intervention.MethodsSentinel surveillance,VCT and respondent-driven sampling were adopted to recruit the target population,and the data was aualyzed with SPSS13.0.ResultsThe average age of normal MSM was 26.45 ± 5.8 and MB was 22.23 ± 3.3.The rates of single,marriaged and divorced about normal MSM and MB were 48.24％,45.53％,6.7％ and 85.4％,9.8％,4.9％ respectively.The educational level of normal MSM(74.8％ )was higher than that of MB(51.22％ ).MB group's rate of condom used(75.61％ ;51.22％ ) was higher than that of normal MSM ( 52.03 ％ ;32.79％ ).There was statistical significance in age,educational level,marital status and infecting rates of HIV between MB group and normal MSM group.ConclusionCompared with normal MSM,MB is the high risk population and bridge population of transmission of HIV.

Objective: To examine the differences on clinical features between DSM-Ⅳ ADHD and ICD-10 HKD patients. Methods:516 children referred to psychiatric clinic because of overactivity, inattention, and impulsivity symptoms were divided into two groups: Children meeting both criteria ( HKD-ADHD group, n=199), and children meeting only DSM-Ⅳ ADHD criteria (ADHD group, n=317). Diagnoses were confirmed by structured interview with parents using Clinical Diagnostic Interview Scale. Results: Whereas the combined type is predominant in HKD-ADHD group (75.4%), predominately inattentive type take account of the majority in ADHD group (67.2%). Compared to ADHD group, HKD-ADHD group includes the patients with younger referral age(9.6?2.2 vs 10.7?2.6) and earlier onset of age(4.6?1.9 vs 5.9?2.5), more opposite defiant disorder comorbidity (41.2% vs 26.2%), more disturbed behaviors, and higher sensory integrative dysfunction prevalence (72.6% vs 56.9% ). However, among the patients not older than 9-year-old there is higher prevalence of learning disability in ADHD group (26.7% vs 14.8%).Conclusion: ICD-10 criteria identified a severe group of patients than those identified by DSM-Ⅳ.However, the patients satisfied only DSM-Ⅳcriteria has exhibited more academic difficulty and behavioral disturbance compared with normal children, so we recommend DSM-Ⅳ as clinical diagnostic tool so that earlier interventions could be possible.

Objective To explore the effects of Interleukin 10 (IL 10) on the endothelial damage mediated by inflammatory cytokines in Kawasaki disease (KD).Methods Human umbilical vein endothelial cells were cultured in vitro and the production of tumor necrosis factor alpha (TNF ?),interleukin 1 beta (IL 1?),interleukin 6 (Il 6) and IL 10 were measured by enzyme linked immunosorbent assay (ELISA).The proportion of apoptotic cells in endothelial cells induced by the supernatants of peripheral blood mononuclear cells (PBMCs) was detected by Annexin V/PI double staining though flow cytometry.Electrophoretic mobility shift assay (EMSA) was used to detect the activity of nuclear factor ?B (NF ?B).Results The level of TNF ?,IL 1?,IL 6 and IL 10 were markedly increased in KD patients and the proportion of apoptotic cells in endothelial cells induced by the cultured supernatants of PBMCs was markedly elevated (38 4?7 8)% compared to (2 8?0 8)% in the control subjects.The apoptosis of endothelial cells induced by the cultured supernatants of PBMCs could be reversed to some degree by anti TNF ?,IL 1? and IL 6 monoclonal antibody (McAb),otherwise could be enhanced (58 6?14 6)% by anti IL 10 McAb.The activity of NF ?B in the activated PBMCs in KD patients was distinctly increased and IL 10 could significantly inhibit the activity of NF ?B,reduce the production of TNF ?,IL 1? and IL 6 and the apoptosis of endothelial cells induced by the cultured supenatants of PBMCs in KD patients.Conclusion IL 10,which can inhibit the activity of NF ?B and the transcription of inflammatory cytokines such as TNF ?,IL 1? and IL 6,acts as an important protective factor in endothelial damage of KD.
