OBJECTIVE:To detect and analyze the drug resistance of the AmpC and the extended-spectrum ?-lactamases(ESBLs)in Escherichia coli(E coli)from urinary infections.METHODS:ESBLs was detected by Phenotypic Confirmatory Test and AmpC was detected by improved three dimensional test.RESULTS:The isolating rates of ESBLs(45 strains),AmpC(8 strains)and AmpC+ESBLs in E.coli(5 strains)were 34.6%,6.2% and 3.8%,respectively.The drug resistance rates of ESBLs and AmpC-producing E.coli was higher than those of the strains without producing ESBLs or AmpC.CONCLUSION:Production of AmpC and ESBLs in ?-lactam antibiotics was the main resistance mechanism against E.coli.Carbopenems should be regarded as the first choice in clinical empirical medication for enzyme-producing strains.

Objective To investigate the expressions and significance of PAX-5, OCT-2 and BOB.1 in Hodgkin lymphoma (HL). Methods Immunohistochemical method was used to detect the expressions of CD30, CD15, PAX-5, OCT-2, BOB.1, CD20 and CD3 in 44 samples of formalin-fixed, paraffin-embedded tissues of HL. The histological classification was carried out according to the WHO classification for tumors of hematopoietic and lymphoid tissues (2001). Results In all 44 cases, 3 (6.8) were nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) and 41 (93.2) were classical Hodgkin lymphoma (CHL). In Hodgkin and Reed Sternberg cells, CD30 were expressed in 36 samples (81.8), CD15 in 27 (61.4), CD20 in 14 (31.8), PAX-5 in 43 (97.7), OCT-2 in 14 (31.8), and BOB.1 in 7 (15.9). All samples of NLPHL expressed OCT-2 and BOB.1, while in the samples of CHL, 30 samples (73.2) expressed both OCT-2 and BOB.1, 7 (17.1) expressed only OCT-2, 1 (2.4) expressed only BOB.1 and all were negative for CD30. Conclusion Hodgkin lymphoma is a rare neoplasm with uncertain cause and difficult to diagnose. The detection of PAX-5, OCT-2 , BOB.1 in combination with CD30, CD15 will conduce to the diagnosis and differential diagnosis of Hodgkin lymphoma.

Objective To investigate the role of FHIT in NSCLC and the relativity between FHIT and cigarette.Methods 81 cases of NSCLC and 7 cases of the nomal lung tisses were examined for FHIT by immunochemical(S-P).Results The postive expression rates of FHIT were significantly lower than those in nomal lung tisses(P

Objective To explore the association of T cell immunoglobulin- and mucin-domain-containing molecule-3 (TIM-3) gene polymorphism and IFN-γ levels with the incidence of primary nephrotic syndrome (PNS) in children. Methods A case-control study was conducted and 21 Han patients with PNS were selected and included in case group. Meanwhile, 20 each from Mongolian and Han were selected and assigned into control group and at least three generations of their family members were from the same nationality. PCR-restriction fragment polymorphism analysis was used to detect and analyze single nucleotide polymorphisms of exon -574A/C in TIM-3 gene in PNS children and controls. Also the genotype and allele frequencies between the two groups were compared. Enzyme linked immunosorbent assay (ELISA) was used to detect the level of serum IFN-γ and its changes was analyzed. Results There was no significant difference in the distribution of genotypes (AA, AC, CC) of exon -574A/C in TIM-3 gene between the Han and Mongolian subgroups in control group (P=0.741). Neither did the allele frequency between the two groups (P=0.655). Compared with control group (Han and Mongolian), the frequencies of AA, AC and CC genotypes were 9.52%, 28.57% and 61.90% respectively in -574A/C loci of the Han nationality children with PNS. There was significant difference in genotypes distribution between the two groups (P=0.017). The frequency of C allele in PNS children of Han nationality was 76.2% which was higher than that in normal control group (50%), and the difference was statistically significant (P=0.005). Compared with A allele carriers, the risk of PNS in C allele carriers increased by 3.20 times (95%CI: 1.39～7.37). There were no significant differences in serum IFN-γ among the Han nationality with PNS, Han and Mongolian normal control groups (P>0.05). Conclusion The single nucleotide polymorphism of the exon -574A/C of TIM-3 gene may be related to the pathogenesis of PNS in children. In addition, IFN-γ is not associated with the incidence of primary nephrotic syndrome in children.

Objective To investigate the pregnancy opportunity and outcome of patients with sysmetic lupus erythematosus (SLE).Methods We carried out a retrospective analysis of the clinical information of patients who suffered from SLE complicated with pregnancy and were hospitalized to People's Hospital of Peking University from December of 1992 to February of 2012.Chi-square test were used for statistical analysis.Results Forty-nine cases of patients with SLE complicated with pregnancy had 52 pregnancies in total.In 27 cases of planned pregnancies,24 cases(89％ )resulted in live births and 5 cases( 18％ ) had flares during pregnancy.Of the 24 live births,3 cases( 12％)were premature deliveries and 4 cases(17％) had low birth weight infants.In 25 cases of unplanned pregnancies,12 cases (48％) resulted in live births and 20 cases (80％) had flares during pregnancy.Of the 12 live births,6 cases(50％ ) were premature deliveries and 6 cases (50％) were low birth weight infants.The patients in the planned pregnancy group tended to have flares during pregnancy more frequently than those in the unplanned group (P＜0.01),the former were more likely to have live births than the latter (P＜0.01) and were less likely to have premature delivery (P＜0.05).Conclusion Patients with SLE should have planned pregnancy and need collaborative supervision of both rheumatology and immunology department and obstetric department to improve live birth rate,decrease premature delivery and the activity of SLE during pregnancy.

ObjectiveTo investigate the age distribution of serum prostate specific antigen (PSA) and explore its correlation with fasting blood glucose(FBG)and lipid in the male elderly.MethodsThe levels of FBG,triglyceride (TG),low-density lipoprotein (LDL-C),high density lipoprotein (HDL-C) and PSA were reviewed in 2903 elderly men (aged ≥ 60 years) in our hospital.The subjects were classified into 6 groups by age,and PSA levels were compared among groups.The correlations of FBG,TG,LDL-C,HDL-C with PSA were analyzed using multiple linear regression analysis.Results The level of PSA had the trend to increase with age.Positive association of TG,LDL with serum PSA level,but negative correlation between HDL and serum PSA level were noted in the group aged 60-64 years (r=0.10,0.15,0.12,P＜0.05).In the group aged 66-69 years,there was negative relationship between FBG and serum PSA(r= 0.10,P＜0.05).No relationship could be found in other groups (P＞0.05).ConclusionsPSA level may increase with age,but without relation with FBG,TG,LDL-C and HDL-C.

Objective: To study the effects of percutaneous coronary intervention (PCI) on blood levels of vascular endothelial growth factor (VEGF), high sensitivity C-reaction protein (hs-CRP) and fibrinogen (Fg) in patients with acute myocardial infarction (AMI).
Methods: Our research included 2 groups: AMI group,n=110 patients with PCI and Control group,n=53 healthy subjects from physical examination. Blood levels of VEGF, hs-CRP and Fg were compared between pre-operation and 30 min, 24 h, 72 h post-operation; the peak values of VEGF, hs-CRP and Fg were compared between the patients with post-operative MACE occurrence at 24 h and the patients without MACE occurrence.
Results:①Compared with Control group, blood levels of VEGF, hs-CRP and Fg in AMI group were increased at pre-operation and 30 min, 24 h, 72 h post-operation, for VEGF (pg/ml) as (84.7±21.4) vs (130.5±40.2) and (143.2±49.7), (107.1±31.8), (97.3±24.4); for hs-CRP (mg/L) as (1.03±0.34) vs (3.11±0.56) and (4.67±0.62), (6.42±0.72), (2.83±0.56); for Fg (mg/L) as (3.86±0.32) vs (4.79±0.52) and (5.02±0.54), (5.54±0.67), (4.11±0.44) respectively, allP<0.05. In AMI group, the post-operative value of VEGF was ifrst increased, it reached the peak at 30 min and then gradually decreasing; while hs-CRP and Fg were increased gradually, they reached the peak values at 24h time point, allP<0.05.②In AMI group, compared with the patients without post-operative MACE (72/110), the patients with MACE (38) had elevated 24h post-operative levels of VEGF as (131.7±36.5 vs 155.5±42.8), hs-CRP as (5.68±0.62 vs 6.89±0.53) and Fg as (5.23±0.60 vs 5.66±0.55) respectively, all P<0.01.
Conclusion: Post-operative monitoring of blood levels of VEGF, hs-CRP and Fg had the important clinical value in AMI patients after PCI.
