ABSTRACT
Objective To assess the role of Matrix Metalloproteinase-9 (MMP-9)in rheumatoid arthritis (RA).Methods Peripheral blood from 45 RA patients and 28 healthy individuals (HV)were collected to detect RF and hs-CRP by immuno-turbidimetry,ESR by westergren method and MMP-9 by ELISA.The correlation was analysed between MMP-9 and RF, ESR or hs-CRP,respectively,by pearson correlation analysis.Results Levels of RF,ESR,hs-CRP and MMP-9 were signifi-cantly higher in RA patients than HV group (t=3.93~5.96,P<0.001),respectively.RF high titer patients or patients with a high inflammation response showed a higher MMP-9 levels than the RF low titer or slight inflammation patients (P<0.05).MMP-9 was positively correlated to RF,ESR and hs-CRP in RA patients(P<0.05),respectively.Conclusion MMP-9 maybe a sensitive tool in the diagnosis and management of RA patients.
ABSTRACT
Objective To investigate the current situation on the infection of Acinetobacter baumannii in ICU and evaluate the efficiency of resistance control project which was performed in Xiaolan hospital,so as to provide scientific basis for clinical rational use of antibiotics.Methods Used VITEK-2 microbiology analysis system for the pathogen identification and drug sensitivity.Compared drug resistance of Acinetobacter baumannii isolated from the samples of ICU patients in 2012 (before the project executed)with that in 2013 (after the project executed).Results 71 strains and 57strains Acinetobacter bauman-nii were isolated from the ICU in 2012 (before the project executed)and in 2013 (after the project executed)respectively, which majorly isolated from the samples of respiratory system,and occupied 94.4% and 84.2% respectively.The infection rate of multi-resistant Acinetobacter baumannii was decreased from 77.5% to 66.7%,and the resistance rate of Acinetobact-er baumannii to cefepime,ceftazidime,cefatriaxone,tobramycin and cotrimoxazole decreased distinctly after the implementa-tion of drug resistance control management (χ2 > 3.84,P <0.05).Conclusion The drug resistance rates of Acinetobacter baumannii to 14 kinds of routine antibacterial drugs in 2013 were lower than that in 2012 in ICU.Among them,the drug re-sistance rates of Acinetobacter baumannii to 5 kinds of antibacterial drugs decreased distinctly.
ABSTRACT
Objective To investigate the relationship of sperm morphology with seminal plasma zinc and sperm acrosin activity in male infertile patients.Methods 455 patients with male infertility were divided into 5 groups and 8 groups according to age and sperm morphology respectively.The sperm morphology,seminal plasma zinc and sperm acrosin activity were detected by the Diff-Quik stain,modified 5-Br-PAPS and modified Kennedy methods respectively.Results The percentages of morphologically normal sperm and seminal plasma zinc concentration in the infertile men groups were not different in various age groups(P >0.05 ).The sperm acrosin activity in the age group of 36-50 years was remarkably decreased (P 0.05).Seminal plasma zinc concentration in the infertile men groups were not different in the 8 groups (P >0.05 ).Sperm acrosin activity was decreased with the percentage decrease of morphologically normal sperm (r =0.93,P <0.01).Conclusion The percentage of morphologically normal sperm is not affectd by the age and the seminal plasma zinc,which is positively correlated with the sperm acrosin activity.
ABSTRACT
Objective To diagnose a rare variant Hb Shaare Zedek in a Chinese family,and describe its clinical feature.Methods Blood samples of seven members of three generation were collected.Standard blood routine analysis,hemoglobin electrophoresis and blood gas analysis were used for phenotype analysis.Gap-PCR and reverse dot blot analysis were used to detect common thalassemia mutations.DNA sequence analysis of the human α and β globin genes were used to identify the mutation site of these samples.Results The result of blood routine analysis was normal in the proband,but a abnormal hemoglobin band (22.4％,capillary assay) was found by hemoglobin electrophoresis.In the blood gas analysis,the partial pressure of oxygen and blood oxygen saturation were 72.0 mm Hg ( 1 mm Hg =0.133 kPa) and 93.0％ in the proband.The heterozygous mutations in αl globin gene at codon 56 ( AAG ＞ GAG)which leaded Glu substitution to Lys were identified in the proband.Other family members who carried the same mutation showed similar phenotype,with abnormal hemoglobin band ( 22.4％ - 23.9％,capillary assay),low partial pressure of oxygen (59.0 - 72.0 mm Hg) and blood oxygen saturation (91.0％ -93.0％).Conclusions The heterozygote of Hb Shaare Zedek leads to slight symptoms with abnormal hemoglobin band,decreased partial pressure of oxygen and blood oxygen saturation.Discovery of this mutation enriches the abnormal hemoglobin spetrum of Chinese people,and it is useful for the clinical diagnosis and genetic counseling of hemoglobinopathies.
ABSTRACT
Objective To explore the association of transforming growth factor-beta 1(TGF-β1) polymorphisms with coronary heart disease(CHD).Methods The 509C/T polymorphisms of TGF-β1 gene were analyzed by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) in 300 patients of CHD and 300 healthy individuals,the levels of serum lipids and hsCRP were also studied.Results The levels of hsCRP、TC 、LDL、ApoB in serum and the frequencies of C、T allele at position-509 of TGF-β1 gene were statistically significant higher than the controls(P＜0.01,P＜0.05).Conclusion The polymorphisms of TGFβ1-509C/T were associated with CHD.C allele should be the susceptibility gene in the occurence of CHD.
