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.

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 The aim of our study was to study the CT findings of cryptococcosis in immunocompetent children.Methods CT scan and clinical data of 21 immunocompetent children with proven pulmonary cryptococcosis were retrospectively collected and analyzed.Results The CT scans demonstrated 1 mm subpleural nodule in the lingula of left lung in 1 patient and multiple nodules in 20 patients.Of 20 patients with multiple nodules,peripheral or subpleural distribution was found in 12 patients,and diffuse distribution in 8 patients.Of 20 patients with multiple nodules,Nodules of ＜ 10 mm was found in 18 patients,＜3 mm in 14 patients,and ＞ 10 mm in 2 patients.Round nodular with smooth margin was detected in 15 of 20 patients with multiple nodules.Lymphadenopathy was found in 17 patients including 3 patients with mild contrast enhancement and 2 patients with circular enhancement.Extrapulmonary lesions distributing in liver,spleen,kidney,and the nervous system were found in 14 patients.In follow-up,1 patient died and 20 patients fully recovered.ConclusionsPulmonary multiple nodules with lymphadenopathy is the characteristic CT findings in immunocompetent children with pulmonary crytococcosis which is prone to involve multiple extra-pulmonary organs.

Objective To understand the perceptions of normal and ideal body size in registered nurses and nursing students,and to analyze the impacts of individual weight levels and misperception of body weight on their such cognitions.Methods A cross-sectional survey of 407 nursing students from two hospitals and 466 registered nurses from one hospital was conducted with the questionnaire survey.Sociodemographic information,actual weight,perceived weight levels and scores for figure rating scale were included.Results FRS scores for normal and ideal body size to male were significantly higher than to female either in registered nurses or in nursing students; FRS scores for ideal body size to both sexes were significantly lower than those for normal body size among registered nurses and nursing students.There were no statistically significant associations between FRS scores for normal and ideal body size and individuals' weight levels and misperceptions of body weight among registered nurses and nursing students.Conclusions There existed differences in rating female and male body size among registered nurses and nursing students,with “bigger” normal and ideal body sizes to male,Nurses preferred to “thinner” ideal body size in comparison to normal body size.

Objective To evaluate the right ventricular (RV) function in patients with acute inferior wall myocardial infarction ( AIMI ) with tissue Doppler imaging and M-mode echocardiography. Methods There were 50 cases of AIMI, 34 males and 16 females. And 50 healthy persons were as control group, 30 males and 20 males. From the echocardiographic apical 4- chamber views, the systolic, early and late diastolic motion (SD, DED, DAD) of the tricuspid annulus were recorded at the RV free wall with the use of two-dimentional guided M-mode recordings. Peak systolic, early and late diastolic velocities (Sm, Em, Am) of the tricuspid annulus were also recorded at the same site by tissue Doppler imaging. The ratios of DAD/DAD and Em/Am were calculated. Results SD, DED, Sm and Em of the tricuspid annulus at the RV free wall, as well as the ratios of DED/DAD and Em/Am, were reduced significantly in patients with AIMI as compared with health control [SD: (18.7±5.5) mmvs. (24.9±2.8) mm; DED: (10.9±3.4) mmvs. (16.6±3.4) mm;Sm: (12.9±2.8) cm/s vs. (15.9±2.7) cm/s; Em: (12.3±3.4) cm/s vs. (16.7±4.7) cm/s;DED/DAD: (1.5±0.6) vs. (2.3±0.9); Em/Am: (0.9±0.4) vs. (1.1±0.3); t=18.711,19. 055, 11. 851, 14. 781, 6.068, 2. 127; P＜0. 01 or 0. 05, respectively]. There were no statistically significant differences in DAD and Am between two groups [DAD: (8. 8±1.9) mm vs. (7.7±2.1)mm; Am: (17.5±4.8) cm/s vs. (16.6±5.2) cm/s; t=0.414, 0.649; both P＞0.05].Conclusions The systolic and diastolic functions of RV are impaired in patients with AIMI.
