Objective To establish two PCR assays to rapidly and simultaneously detect U.parvum and U.urealyticum.Methods Two PCR assays were established through designing two sets of specific primer targeting urease gene B of U.parvum and U.urealyticum,respectively.The standard strains of U.parvum and U.urealyticum and the clinical samples were detected by these PCR assays and PCR products of the standard strains and two clinical specimens were directly sequenced and carried out specific and sensitive assays.Forty-eight clinical specimens were tested for culture and the PCR assays and tow methods were compared.Results The standard strains of U.parvum,U.urealyticum and the clinical specimens were successfully and differentially detected by the PCR assays and the sequencing results were found to have a complete similarity to the GenBank sequences.The 14 strains of other bacterial genera including 5 strains that produced urease were not amplified by these PCR assays.Each assay had a detection limit of 10 copies/?l of plasmid DNA.The positive rate in 48 clinical specimens by PCR(54.2%)was higher than that by culture(39.6%)(P

Recently,the techniques for proteomics have made remarkable progress.They are widely used in various fields of life sciences,providing strong technical supports for relevant researches.Especially,proteomics technology has made prominent contributions to drug development and mechanism studies,magnificently improving the efficiency of discovering new drugs.This paper summarizes the classical method and new technology of proteomics.Also,its applications in drug study,including targets screening,mechanism studies,drug toxicology,researches of resistance mechanisms and clinical medical studies have been reviewed.

Objective To investigate the prognosis and survival situation of the patients with high risk refractory lymphoma treated by autologous hematopoietic stem cell transplantation .Methods The follow up data in 110 patients with high risk refractory lymphoma treated by autologous hematopoietic stem cell transplantation in our hospital were retrospectively analyzed .The survival and prognosis factors of the patients after autologous hematopoietic stem cell transplantation were analyzed by using the Kaplan-Meier survival analysis and Cox proportional hazard regression analysis .Results The median survival time was 39 .4 months in 110 cases ,the 3‐year overall survival rate (OS) and progression free survival rate (PFS) were 80 .9% and 76 .4% respectively .The pa‐tients achieved CR status before transplantation(P=0 .016) and consolidation therapy after transplantation (P=0 .006) were the favorable prognostic factors of the patients undergoing transplantation .The prognosis in the patients with high LDH values ,IPI score>2 and bone marrow infiltration and HBV infection were poor(P<0 .05) .Conclusion Autologous hematopoietic stem cell transplantation can improve the long‐term survival rate in the patients with high risk refractory lymphoma .

Objective To investigate the effects of benazepril on plasma copeptin and N terminal brain natriuretic peptide (NT-proBNP) in the patients with chronic heart failure (CHF) in order to explore the mechanism of benazepril on ventricular remodeling.Methods Two hundred and thirty-eight patients with CHF were randomized into control group (n =118) and therapy group (n =120).Patients in control group were received regular treatment including medicine of treating cardiotonic diuretic and vasodilator for 6 months,while in therapy group were given benazepril beside regular treatment.The levels of copeptin,NT-proBNP were measured before and after treatment.The left ventricular ejection fraction (LVEF),left ventricular end systolic diameter(LVESD) and left ventricular end diastole diameter(LVEDD) were recorded and compared before and after treatment.Results In treatment group,the levels of copeptin and NT-pro BNP,LVEF,LVEDD,LVESD were (4.9 ± 1.3) pmol/L and (327.8 ± 226.8) ng/L,(33.5 ± 6.2) ％,(47.6 ± 8.9) mm,(60.2 ± 7.1) mm before treatment,different from that after treatment ((17.8 ± 7.9) pmol/L,t =7.331,P =0.008 ; (1 779.6±838.3) pg/mL,t =10.236,P =0.002; (50.5 ±5.2)％,t =3.336,P=0.009;(32.9 ±5.7) mm,t =2.767,P =0.010 ; (43.2 ± 5.6) rmm,t =2.882,P =0.009).After treatment the levels of copeptin,NT-proBNP,LVEF,LVESD and LVEDD in treatment were lower than that of control group(control group:copeptin:(10.5 ± 2.4) nmol/L; NT-proBNP:(1076.6 ± 486.6) pg/L; LVEF:(36.6 ± 5.6) ％ ; LVESD:(45.9 ± 6.8)mm; LVEDD:(57.5 ± 5.4) mm),and there was significant difference between groups (P =0.049,0.010,0.035,0.038,0.048 respectively).Conclusion Benazepril treatment could decrease the level of plasma copeptin and NT-proBNP in CHF patients,inhibit neuroendocrine and the ventricular remodeling,and then improve the heart function.

Aim To study the effect of echinacoside on behavior and proteins expression from substantia nigra and striatal tissue in MPTP mouse model of Parkinsons disease(PD)and discover the mechanism of its potential dopaminergic neuroprotective effect in the protein level.Methods The mouse model of PD was induced by 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)and the behavioral analysis of C57BL/6 mice was performed by using spontaneous movement and rotarod test.A proteomic approach based on 2-dimensional electrophoresis(2-DE),mass spectrometry(MS)and figure analysis was used to evaluate the effect of echinacoside on the behavior and the protein expression in substantia nigra and striatal tissue in C57BL/6 mice after MPTP administration.Results ① Compared with control,MPTP lesion significantly reduced the number of spontaneous movement and latent period of mice on the rotating rod(both P

Objective To Analyze the effect of community-based integrative intervention on hypertension.Methods Among six residential areas,randomly chose four as the intervention group and the another two as the control group.Then a synthetical intervention was carried out to the intervention group,but no measures to the control.Results In the intervention group,the patients' systolic and diastolic pressure were eventually lower by 5.25 mm Hg than the datum line.The final result was obviously different from the datum line(P0.05).Conclusion The community-based integrated intervention plays a great role in the control of high blood pressure.

The effects of a new crystallization form A famotidine ( F_A ) on experimental gastric ulcers in rats, and compared the antiulcer effects of F_A with those of the form B of famotidine(F_B)were investigated . F_B has been used in clinic.The results showed that the anti-ulcer effects of F_A were as same as F_B and both of F_A and F_B were dose- dependent manner.
