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.

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.

ObjectiveTo guide fluid management and evaluate the clinical index through monitoring extravascular lung water index(EVLWI) of patients with pulmonary contusion.MethodsThirtyone severe chest trauma patients with pulmonary contusion were selected,performed with central venous catheterization or femoral artery catheterization,and connected to pulse index continuous cardiac output (PICCO).EVLWI after pulmonary contusion were measured by using thermal dilution.The intake and output of patients were recorded in detail,fluid intake was controlled,furosemide was prescribed,and the changes and correlations of oxygenation index,EVLWI and liquid balance difference at different time points were evaluated.ResultsEVLWI after pulmonary contusion at 1st to 7th d after hospitalization was respectively (9.25 ±0.71),(8.98 ±0.61),(8.61 ±0.59),(7.75±0.53),(6.64 ±0.49),(6.22±0.36),(5.59 ±0.39) ml/kg.Comparing with 1st d after hospitalization,EVLWI declined from 3rd d (P ＜ 0.05).Oxygenation index at Ist to 7th d after hospitallzation was respectively( 145.76±23.61 ),( 144.19±20.24),( 146.67±19.25 ),(159.33±15.42),(177.38±14.25),(199.33±19.04),(213.71±18.51) mm Hg(1 mm Hg =0.133 kPa).Comparing with 1st d,oxygenation index from 4th to 7th d had significant difference (P ＜ 0.05 ).The fluid volume at 1st d to 7th d were all negative balance,that of 3rd d to 6th d had significant difference comparing with 1st d [(-431.43±121.17),(-601.43±127.09),(-629.52±140.69),(-320.01 ±93.71) ml vs.(-213.81±63.91 ) ml](P ＜ 0.05 ).Oxygenation index and EVLWI had negative correlation(r =-0.824,P＜0.01).Liquid balance difference and the changes of oxygenation index and EVLWI had no correlation.ConclusionEVLWI effectively monitoring after pulmonary contusion can not only evaluate the changes of pulmonary vascular permeability of patients with pulmonary contusion,but also have important significance to guide fluid management.

BACKGROUND: Prospective studies concerning bone metabolism and bone mineral density variation after fractures have been reported from the 1960s, but these studies are mainly focused on tibia and fibula and ankle fractures in patients with low sample size.
OBJECTIVE:To observe the changes in bone mineral density and bone metabolism indexes in elderly women within 6 to 12 months after hip fractures, and to analyze the correlation.
METHODS:We selected 48 elderly women with hip fractures admitted in the Department of Orthopedics, Beijing Aerospace General Hospital in China from May 2011 to July 2013. Standards for fol ow-up were developed to measure the bone mineral density and bone metabolism indexes in the L 1-4 spinal segments and both sides of the hip. The bone metabolism indexes included bone alkaline phosphatase, osteocalcin, cross-linked C-terminal peptide of col agen I, and serum tartrate-resistant acid phosphatase 5b levels. Multiple linear regression analysis was performed based on measurements of bone mineral density and bone metabolism indexes after fracture healing.
RESULTS AND CONCLUSION:After fracture healing, bone mineral density of the fractured hip and lumbar vertebra was significantly lower than the baseline value. There was no statistical difference in bone mineral density between the healthy hip and the baseline value. At 6 months after fractures, bone alkaline phosphatase, osteocalcin, cross-linked C-terminal peptide of col agen I, and serum tartrate-resistant acid phosphatase 5b levels were significantly higher than the baseline values. At 12 months after fractures, osteocalcin level was significantly higher than the baseline value, while other indexes of bone metabolism measurements showed no statistical difference from the baseline values. When healing of hip fractures met the clinical and radiographic standards, the partial regression coefficient of delta-Z score reached peak in the changes of serum osteocalcin and bone mineral density of the fractured hip. Under clinical healing of fractures, serum osteocalcin level exhibits a higher value for the assessment of recovery speed of bone mineral density. Monitoring corresponding bone metabolism indexes after fracture healing can improve the accuracy of judging bone mineral density changes to reduce the risk of secondary fractures.
