Objective To investigate the status of urogenital Ureaplasma urealyticum (Uu) infection and their drug tolerance in our area,so as to guide rational administration for the clinic.Methods Mycoplasma culture and drug susceptibility test were performed for 771 patients with urogenital infaction. The culture,identification and drug resistance of mycoplasma were carried out with one complex mycoplasma kit.Results The positive rate of Uu was 49.9%. The proportional percentage of males was 12.5% and the Uu positive rate was 22.3%,for females,the proportional percentage and Uu positive rate was 87.5% and 60.6% respectively. The population aged 21-40 was susceptible to Uu infection. The most sensitive antibioties to Uu was clindamycin (95.12%),followed by doxycycline (87.57%) and roxithromycin (86.24%).Conclusion The difference of Uu drug sensitivty was significant in different areas. So it is necessary to select antibioties by drug sensitivity. Clindamycin,doxycycline and roxithromycin may are used as preferred antibioties in treating Uu infection in our area. The drug-resistance status of spectinomycin and lincomycin was serious.

Objective To analyse the effective rate and adverse effect of only levetiracetam (LEV) versus LEV plus other drugs in the treatment of middle and old aged patients with partial seizures (PS) and secondary generalized tonic-clonic seizure (SGTCS).Methods The self-control study was used and 59 elderly patients with PS and SGTCS were treated with LEV single or plus drug (therapeutic dose was 1000-2000 mg/d,bid).The effective rate and the side effects of LEV were observed and compared between LEV single and plus drug or between the patients with only epilepsy versus epilepsy plus other diseases,respectively.Results The effective ratios at the end of 3,6,9and 12 months after LEV treatment were 76.2％,70.6％,64.3％ and 66.7％,respectively and there were no significant difference among above time points (x2=1.911,P＞0.05).A chi-square test showed that the differences in effective ratios were not statistically significant (P＞ 0.05) between single and combination of drugs (x2 =1.437) and between two groups of patients at the end of 12 months.Clinical effect of LEV showed no remarkable difference between different types of epilepsy at the end of 6 months (x2 =1.315,P＞0.05)and 12 months(x2 =2.700,P＞0.05).The control ratio of epileptic attack was higher in single LEV than in combination drugs (x2 =10.83,P＜0.05).The total side effects were 13.6％,including somnolence,weakness,anorexia,headache,irritability and forgetfulness.Conclusions The curative effects of levetiracetam single or in combination are definite,stable and continuous for PS and SGTCS,especially in combination with other diseases.

Objective To investigate the clinical value of serum soluble intercellular adhesion molecule-1 (sICAM-1 )in patients with primary biliary cirrhosis (PBC)and autoimmune hepatitis (AIH).Methods Sixty-one PBC patients and 59 AIH patients,who were hos-pitalized or visited the outpatient department from June 2012 to September 2013,as well as 50 healthy controls,were included in the study. The PBC patients included 29 incipient cases,21 cases in remission,and 11 recurrent cases;the AIH patients included 26 incipient cases, 20 cases in remission,and 13 recurrent cases.Serum sICAM-1 level was measured by double-antibody sandwich enzyme-linked immu-nosorbent assay,and serum levels of alanine aminotransferase (ALT)and total bilirubin (TBil)were determined by biochemical enzyme as-say.Comparison between groups was made by analysis of variance;Pearson correlation analysis was performed.Results Among PBC pa-tients,the incipient group and recurrent group had significantly higher serum sICAM-1 levels than the remission group and control group (P=0.000 for all);there was no significant difference in serum sICAM-1 level between the incipient group and recurrent group (P=0.484);the remission group had a significantly higher serum sICAM-1 level than the control group (P=0.000).Among AIH patients, the incipient group and recurrent group had significantly higher serum sICAM-1 levels than the remission group and control group (P=0.000 for all);there was no significant difference in serum sICAM-1 level between the incipient group and recurrent group (P=0.802);no significant difference in serum sICAM-1 level was seen between the remission group and control group (P=0.281).For patients with PBC and AIH,serum sICAM-1 level was positively correlated with serum levels of ALT (r=0.664,P=0.000;r=0.784,P=0.000) and TBil (r=0.715,P=0.000;r=0.580,P=0.000).Conclusion Serum sICAM-1 may be involved in the immunologic injury in PBC and AIH.In patients with PBC and AIH,the elevation of serum sICAM-1 level is closely correlated with the severity of liver damage. Clinical monitoring of serum sICAM-1 level may play an important role in severity assessment,prognostic evaluation,and therapy guidance among patients with autoimmune liver diseases.

Objective To investigate the molecular mechanism of Klebsiella pneumoniae resistant to imipenem.Methods Anti-microbial susceptibility was evaluated by disk diffusion test,Seven imipenem-resistant strains of Klebsiella pneumoniae were select-ed.And PCR was used to amplify so as to detect eighteen resistant genes.Results Seven imipenem-resistant strains of Klebsiella pneumoniae were more sensitive to aminoglycosides and sulfamethoxazole/trimethoprim.The positive rates of KPC,ant(3′′)-Ⅰ, SHV,CTX-Mand ant(2′′)-Ⅰin these imipenem-resistant strains were high.Conclusion Carbapenem-resistant Klebsiella pneumon-iae isolated from our hospital carries several kinds of resistant genes.Carrying KPC may be the main resistant mechanism of Kleb-siella pneumoniae resistant to carbapenem,but other mechanisms also exist at the same time.

Objective To explore the relationship between blood lead and general symptoms in pediatric clinic.Methods Levels of the blood lead of 487 cases with symptoms and 80 normal children as control group were determined by atom absorbent spectrophotometry.Results The blood lead level in patient group was higher than that in control group(P

Objective To explore the operational indications, preoperative evaluation,operative essentials and clinical prospect of endovascular repair(EVR) for aortic dissection.Methods Twenty-six patients underwent EVR for aortic dissection and all cases were Stanford B dissection.Four patients had two or more tear entries in different sites.Computed tomography angiography(CTA) or digital subtraction angiography(DSA) were used as preoperative evaluation methods.Results The grafts were installed successfully in 26 patients(100%).The patients were followed up for 1 to 18 months after treatment,and there was no endoleaks and organ or limb ischemia in all the patients.Conclusion Endovascular repair was simple,safe and effective in treating aortic dissection and dissecting aneurysm.

Objective:To explore antitumor mechanism of a recombinant vaccinia virus expressing human carcinomembryonic antigen(rV CEA).Methods:C57bl/6 mice were immunized three times with rV CEA.Six weeks later,the splenocytes from rV CEA immunized donors were adoptively tranfered in sublethally irradiated CEA + HePa bearing recipients,meanwhile the antiumor effect of the donor splencytes in virtro was detected.Results:Splenocytes from rV CEA immunized donors expressed strong antiumor activity in CEA positive tumorbearing recipients,whereas W VV immunized and nonimmune donor cell did not.The antiumor activity was abolished when immune T cells were depleted before splencytes transfer.Conclusion:It was demonstrated that antiumor acivity induced by rV CEA was essentially mediated by immune T cells which were activated by CEA specific immune response.Adoptive immunotherapy strategies may have implications for both the study of rV CEA and the development of potential clinical applications for tumor immunotherapy.

The study is designed to investigate if human interleukin 18 (hIL-18) cDNA expressed in nasopharyngeal carcinoma (NPC) cells could enhance the cytotoxicity of CD8+ T cells from the PBMC of the MFC-bearing patient and how to enhance it.Methods: A constructed eukaryotic expression vector for human IL-18 ,pcDNA3.1(-)/hIL-18, was used to transfect the NPC cell strain-SUNE cells. Then, the transfected SUNE cells were mix-cultured with CD8+ T cells which were separated from the PBMC of the patient with NPC, the cytotoxicity was measured by lactate dehydrogenase(LDH) releasing method, the expression for Perforin, Fas-L and Granzyme B were detected with the mix-cultures. Results: The eukaryotic expression vector could highly express hIL-18 in transfected SUNE cells and only traces of the protein exist in non-transfected SUNE cells. The concentration of hIL-18 in supernatant of the transfected SUNE cells was (85 ? 10) pg/ml, but less than 5 pg/ml of hIL-18 contained in supernatant of the non-transfected SUNE cells.The expression of hIL-18 in SUNE cells could enhance the cytotoxicity of CD8+ T cells from the NPC patient significantly( P
