Objective To study the relationship between the constant work rate exercises and dynamic hyperinflation in patients with stable COPD. Methods Routine lung ventilation function and 80%Wmax constant power bicycle ergometer exercises were tested in 30 stable COPD patients. We analyzed the correlation coefficient of Time of tolerant exercise , degree of dyspnea , VO2 max%, VO2 @kgmax% and IC%. Results All COPD patients existed varying degrees of exercise capacity accompaning with dynamic hyperinflation in the bicycle ergometer exercises. By Spearman correlation analysis , the VO2 @kg% of constant power exercises in patients with COPD is correlated with the DH% (r = -0.480, P = 0.007) and ICq% (r = 0.667, P = 0.01). Conclusion Dynamic hyperinflation is probably the prominent factors for the capability of constant work rate exercises in patients with stable COPD. Inhibition of dynamic hyperinflation may help improve exercise capability in patients with constant power exercise.

Objective To study the differentiation of embryonic stem cells(ESCs) induced by transforming growth factor-?_1(TGF-?_1) and co_cultured with visceral endoderm like END_2 cells,and explore cardiomyocytes induction effects of the combined techniques Methods Day 2-3 embryoid bodies(EBs) were derived from ESCs,and then TGF-?_1 was added or/and co_cultured with END_2 cells or END_2 cells conditioned medium.Spontaneous differentiation was as a control.The expression of cardiac specific ?-sarcmeric actin(?-actin) and cardiac troponin_T(TnT) was detected by immunofluoresence staining.The ultrastructural analysis for ESCs_derived cardiomyocytes was scanned by transmission electron micrograph. Results The total percentage of beating EBs treated with TGF-?_1,co_cultured with END_2 cells,or END_2 cell conditioned medium was(43?2.08)%,(69?3.61)%,(65?3.06)%,respectively.All the beating cardiomyocytes derived from ESCs expressed cardiac_specific proteins for ?-actin and TnT,and could be observed the cardiac_specific ultrastructure.Interestingly,the total percentage of beating EBs treated with the combined method was(91?1.52)%.(P

Objective To investigate the significance of antifilaggrin autoantibodies (AFA) in rheumatoid arthritis (RA).Methods Filaggrin was extracted from the skin of the patients who had breast cancer undergoing mammectomy.AFA were detected at the sera titer 1∶10 with Western blotting,and its clinical significance was investigated with the corresponding clinical materials.Results Antifilaggrin autoantibodies (AFA) were detected in 39 9%(71/178) of RA patients,and 6 cases of control group,with a specificity of 0 969.AFA were present in 48 4%(15/31) of the early and 29 2% of seronegative RA.AFA positive patients exhibited higher frequency of Sjgren′s syndrome;The average and onset ages of AFA positive patients were older than those of the negative ones,and there was correlation between AFA and age.The frequency and average titer of RF patients were higher in AFA positive than in negative ones.AFA was significantly correlated to RF,AKA and APF.Conclusion AFA are valuable diagnostic parameter for RA,especially in the early and seronegative RA.AFA is significantly correlated to AKA and APF,but they are not totally overlapped,None of the three antigens used bear all the epitopes recognised by antifilaggrin autoantibodies.Immunoblot detection of AFA,a simple and reliable test,may be complement to conventional IIF detection of AKA and APF.
