Objective To compare the effect of L-T4 taken in the morning vs bedtime on serum thyroid hormone in patients with hypothyroidism.Methods Seventeen patients with primary hypothyroidism were prospectively included.They took L-T4 in the morning for 2 months followed by L-T4 taken during the bedtime for 2 months.Thyroid hormone levels and cholesterol,triglyceride,albumin,creatinine and heart rate were measured.Wilcoxon test and paired t test were used to compare the data.The correlation between the changes of TSH and FT3,FT4 was analyzed respectively by Pearson correlation analysis.Results TSH,FT3,FT4 were:(12.10±7.19) vs (3.90±3.47) mU/L,(4.14±0.86) vs (5.24±1.11) pmol/L,(12.72± 4.40) vs (18.48±2.87) pmoL/L for L-T4 taken in the morning and during the bedtime respectively (t value:6.371,-3.166,-5.435,all P<0.01).There was no correlation between the changes of TSH and FT3,FT4(r=O.12,0.22,both P>0.05),respectively.The averaged changes were (8.20±5.31) mU/L,(1.09± 1.42) pmol/L and (5.76±4.37) pmol/L.Triglyceride,cholesterol,albumin,creatinine levels and heart rate were not significantly different with L-T4 taken in the morning and during bedtime (t=0.240,0.017;z=0;t=-0.610,1.588,all P>0.05).Conclusions L-T4 taken during the bedtime by patients with hypothyroidism would reduce TSH and increase FT3,FT4 levels.This method can maintain the stability of TSH level with no need to increase the dose.

Objective To investigate the changes of airway resistance before and after Bronchial Diulation Test in patients with senile asthma and the effect of age on the degree of airway resistance. Methods A total of 29 (> 60 years)senile asthma patients and 21 younger(< 60 y)patients were enrolled in the study. The status of their pulmonary function was determined by MEFV(Maximum expiratory flow?volume curve)and an IOS(impulse oscillometry) system before and after Bronchial Diulation Test,The spirometric indexes such as forced vital capacity,total respiratory impedance,respiratory resistance and respiratory system reactance were collected and analyzed. Results Significant decreases of indexs were found after Bronchial Diulation Test compared with those before Bronchial Diulation Test in the study group(P<0.05,respectively). No significant difference in improvement of indexs was found between the group of patients with senile asthma(age > 60 years)and the group of healthy control(age < 60 years ). Each index of the airway resistance has a very good correlation with FEV1%,with the highest degree of relation is X5%. Conclusion The airway resistance of senile asthmatic patients was significantly improved after diuslation test and these indexes IOS would be valuable in evaluating the changes of airway resistance of senile asthma.

Objective:To establish a mouse fibroblastic cell line stably transfected with HMGA1 gene,and to use the cell line to investigate the role of HMGA1 in tumor development and progression.Methods:Eukaryotic expression vector pcDNA3.0-HMGA1 was transfected into NIH3T3 by lipofectamine-mediation.Stable transfectants were selected by G418.The expression of extraneous HMGA1 gene was analyzed by RT-PCR and DNA sequencing.Cell growth was measured through MTT and the cell cycle by FCM.Soft agar colony formation was employed to analyze the ability of anchorage-independent growth.The expression of the immune inhibition factors of VEGF and FasL mRNA was detected by RT-PCR.Results:NIH3T3 cell lines stably expressing HMGA1 gene were successfully established.Comparing with controls,the HMGA1 gene-transfected cells grew faster,acquired the ability of anchorage-independent growth and expressed the immune inhibition factors of VEGF and FasL mRNA.Conclusion:Extraneous expression of HMGA1 gene can induce malignant transformation of NIH3T3 and modulate mRNA expression of immune inhibition factors.HMGA1 gene plays a key role in tumor development,progression and immune escape.

OBJECTIVE To analyze the isolation rate and four consecutive years′(2004-2007) antibiotic-resistance trend of extended-spectrum ?-lactamases(ESBLs) producing Escherichia coli in urinary tract infection and to provide evidence for anti-infection therapy.METHODS The anti-microbial susceptibility test results of E.coli cultured from the midstream urine of outpatients and inpatients of our hospital from 2004 to 2007 were collected.Whonet 5.4 statistical analysis software was used for analysis.RESULTS During four years,no apparent change has been shown about antibiotic resistant rate of ESBLs producing E.coli.The isolation rate of this kind of E.coli increased year by year from 31% to 44% and showed high resistance to third generation cephalosporins and quinolones antibiotics,but was 100% sensitive to imipenem.CONCLUSIONS With the ESBLs-producing E.coli increasing year by year,the antibiotic-resistance rate of E.coli isolated from urinary tract infection is apparently increased and thus screening of antibiotics sensitive to enzyme-producing bacterial is the key point when the empirical therapy especially when the third and fourth generation cephalosporins are ineffective.

Because the influence of fibrin on the reaction of plasm inogen activation by various plasminogen activators is different, the kinetic co nstant of the reaction of plasminogen activation catalyzed by InB with and witho ut fibrin were detected. The result is: Kfibrinm=4.2 μmol*L -1,greater than the normal Km=0.379 μmol*L-1; kfib rincat=0.107 s-1,greater than the normal kcat=0.0165 s-1. The results suggest that existence of fibrin in the reaction system of plasminogen activation depress the affinity between InB and plasminog en, but accelerates the hydrolysis of plasminogen by InB. The count up effect is inhibition.

Objective To study the strategy of expanding standard donor heart application and to analyze the clinical effect on applying expanding standard donor heart in heart transplantation.Methods 146 patients received heart transplantation in Fuwai Hospital Bering from June 2004 to February 2009.Expanding standard donor heart was defined as prolonged ischemic time over 6 h,advanced age up to 40,and blood type ABO mismathched.Blood type examination and PRA test were done before operation.The donor heart was preserved by sequential perfusion with cold St.Thomas and HTK solution.The patients were divided into groups according to different oversize body weight,ischemic time,and donor age Results There were 11 deaths after operation.Ischernic time of donor heart was 262.1±120.8 min,and that of 21 donors was over 360 min(the longest one was 605 min).There was no significant diffeFence in recipient properties before transplantation.and also there was no significant difference in mortality,heart function,heart rejection,and main morbidity after transplantation and during follow-up.Conclusion These data support continued aggressive utilization of expanding standard donor hearts in heart transplantation.Our experience demonstrates thatproperly expanding standard cardiac allografts application has no effects on the short- and long-term clinical outcome following heart transplantation.
