BACKGROUND:Now a correspondingly stable project was performed in the rehabilitative treatment for patients with chronic heart failure in China,but it was difficult to be carried out on the wide range because of difficulties in adjusting movement capacity,lower compliance and so on,especially for the elder patients or those with severe chronic heart failure.The movement project will be required with the advantages of good compliance,moderatemovementcapacityandreproducibilityin clinic.OBJECTIVE:To investigate the change of exercise tolerance and cardiac function after the intervention in movement training in patients with chronic heart failure.DESIGN: Randomized and controlled observation.PARTICIPANTS:Seventy inpatients with stable chronic heart failure were chosen from the Department of Gerontology in Wuhan Union Hospital of Hubei Province from August 2002 to October 2003.All patients agreed to this test. Functional class of New York Heart Association (NYHA)was (2.69±0.13).Chronic heart failure duration of all patients was over six months. Seventy patients were randomly divided into movement group(n=34) and control group(n=36).In the movement group with 19 males and 15 females,functional class was(2.68±0.12).In the control group,there were 19 males and 17females.METHODS:Thepatientsinthemovementgroupunderwentthree weeks of movement training (bicycle ergometer,treadmill walking and walking on foot). The patients in the control group underwent three weeks of activity restriction. All patients received the 6-minute walking test under the condition of the same rating of perceived exertion before and after the test. Totally 5 mL of venous blood was drawn without eating anything in the morning before and after the test.The levels of interleukin-6 and norepinephrine were evaluated and left ventricle ejection fraction was observed and determined.MAIN OUTCOME MEASURES:Comparison of walking distance,interleukin-6,norepinephrine,l.eftventricleejectionfractionandcardiac functional class before and after the intervention in all patients.RESULTS:Seventy patients with chronic heart failure were involved in the statistical analysis at last. After the intervention,walking distance covered during 6minutes and left ventricle ejection fraction in the movement group were obviously longer and higher than those before the intervention and in the control group [(385±30)m,(43±5)％;(324±35)m,(39±6)％;(292±30)m,(35±4)％,P＜ 0.05].After the intervention,the levels of plasma interleukin-6 and norepinephrine and cardiac functional class in the movement group were lower than those in the control group and before the intervention[(0.86±0.25) pmol/L,(2.05±0.48) nmol/L,(1.89±0.11);(1.00±0.25)pmol/L,(2.21 ±0.47)nmol/L, (2.45 ±0.12);(1.12±0.23) pmol/L,(2.46 ±0.53) nmol/L,(2.68±0.12),P＜ 0.05-0.01].CONCLUSION:Theprojectof movementtrainingdesignedinour study can improve exercise tolerance and ameliorate cardiac function in patients with chronic heart failure. This project has the advantage of better compliance designed according to oneself.

Objective To investigate the effect of skeletal muscle training on exercise tolerance in patients with chronic heart failure(CHF). MethodsSeventy patients with CHF were divided into group A( n =34),undergoing 3 weeks of exercise training(bicycle ergometer, treadmill walking and walking on foot),and group B( n =36), undergoing 3 weeks of activity restriction. Before and after exercise training and after activity restriction, 6 minutes of walking test was performed and levels of interleukin-6(IL-6), norepinephrine(NE) and left ventricle ejection fraction(LVEF) were evaluated. ResultsAfter exercise training in group A, the maximum distance walked was (385?30.12)m. The levels of LVEF, plasma IL-6 and NE were (43?5.23)%,(0.86?0.25)pmol/L and (2.05? 0.48 )nmol/L,respectively. All the above parameters were significantly ameliorated when compared with group B ( P 0.05). ConclusionThe skeletal muscle training could improve exercises tolerance and ameliorate cardiac function in patients with chronic heart failure,which was beneficial for the rehabilitative treatment.

AIM: To screen macroreticular resins for isolation and purification of flavonoids from the leaves of Diospyros kaki Linn (FLDK). METHODS: 8 kinds of macroreticular resins were assayed for their adsorbability and deadsorbability as well as the adsorption kinetics to FLDK. RESULTS: Polyamide and AB-8 resin were found with good adsorbability and deadsorbability as well as adsorption kinetics to FLDK. CONCLUSION: AB-8 resin and polyamide could be used for preparing high contents of FLDK. FLDK-P70, a flavonoid extract contained more than 77% of flavonoids was prepared from the extract of leaves of Diospyros kaki by polyamide adsorption column isolation.

Objective To explore the effects of physical training on serum activity of some peripheral inflammatory markers associated with endothelial dysfunction, such as granulocyte macrophage-colony stimulating factor (GM-CSF), macrophage chemoattractant protein-1 (MCP-1), soluble intercellular adhesion molecule-1(sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) in patients with chronic heart failure. Methods Forty-eight patients were enrolled and randomly divided into two groups: a training group and a rest group. The patients of both groups were both given conventional internal medicine therapy, and the patients of the training group were given physical training in addition. The serum levels of GM-CSF, MCP-1, sICAM-1 and sVCAM-1 in patients of the two groups were determined with stable chronic heart failure before and after 12 weeks of programmed physical training. At the same time, the motor functional status of chronic heart failure patients was evaluated by using the 6-minute walking test. Results It was shown that the physical training produced a significant reduction in serum GM-CSF, MCP-1, sICAM-1 and sVCAM-1 as well as a significant improvement in performance of the 6-minute walking test. Conclusion The physical training could significantly alleviate the inflammation reaction and improve the motor function of patients with chronic heart failure.

AIM: To study the effect of tick anticoagulant peptide-staphylococcal superantigen like protein 5 (TAP-SSL5), an anti-inflammatory and anticoagulant fusion protein , on the binding of activated platelets to human lym-phocytes.METHODS:Human periphery lymphocytes were isolated by magnetic activated cell sorting (MACS).The toxic-ity of TAP-SSL5 on the viability of Jurkat cell was assessed by CCK-8 assay.Flow cytometry was applied to detect the ex-pression of CD162 (PSGL-1) on the Jurkat cells (human peripheral blood leukemia T lymphocyte cell line ) and the inhibi-tory effect of TAP-SSL5 on the binding of mouse anti-human CD162 monoclonal antibody (KPL-1) to Jurkat cells.Platelets were activated by ADP at concentration of 20μmol/L, the binding rates of activated platelets to Jurkat cells or human lym-phocytes were assayed by flow cytometry .RESULTS:The concentration of TAP-SSL5 below 30 mg/L didn’ t affect the vi-ability of Jurkat cells .TAP-SSL5 at 10 mg/L competitively inhibited KPL-1 binding to Jurkat cells .The binding rates of activated platelets to Jurkat cells or lymphocytes were (11.86 ±4.49)% and (8.32 ±1.00)%, respectively, which de-creased to (6.73 ±2.71)%and (5.51 ±0.70)%after the Jurkat cells and lymphocytes were pre-incubated with 10 mg/L TAP-SSL5 (P <0.05).CONCLUSION:TAP-SSL5 binds to PSGL-1 expressed on lymphocyte surface and directly in-hibits the binding of activated platelets to human lymphocytes , which may be one of the anti-inflammatory mechanisms of TAP-SSL5.
