Objective To investigate the influence of six-minute walking training on autonomic nerve function in patients having chronic heart failure.Methods Eighty chronic heart failure patients with heart function Ⅱ-Ⅲ grade were divided into training group (40 cases) and control group (40 cases) by random digits table method.Patients in two groups were treated with conventional anti heart failure drug.Patients in training group insisted six-minute walking training twice a day on the basis of the conventional treatment.Changes of the index of heart function,heart rate variability (HRV) and heart rate deceleration force (DC) before and after treatment were tested in two groups.Results After treatment,the cardiac function in training group and control group was significantly improved (P ＜ 0.05).The indexes of HRV and DC in two groups were significantly higher than those before treatment (P ＜ 0.05).After treatment,the indexes of HRV and DC in training group were significantly higher than those in control group (P ＜ 0.05).Conclusion Six-minute walking training in patients having chronic heart failure can significantly improve the autonomic nerve function,which is an effective and safe rehabilitation exercise for patients having chronic heart failure.

Objective To study the relationship between pedometer-based daily physical activity and obesity measurements in adult male leaders living in countryside.Methods A total of 136 men who received routine health screening were measured for body weight,body mass index (BMI),waist circumstance,and total body fat.Daily walking activities were determined by pedometer for 7 days.Results Ⅰ to Ⅱ grade walking activities was found in 58% participants.Daily physical activities were negatively correlated with body weight,waist circumference,BMI and total body fat.Body weight,waist circumference,BMI and total body fat were almost normal when walking activities increased to Ⅲ grade.Only 7% of the subjects participated in exercises.Conclusion Pedometer-based daily physical activities may be significantly correlated with obesity arameters.Increased walking activities will help to loss weight.

Objective To obtain informatization of the mobile medical service units,and gift them with enhanced war preparedness management.Methods Based on previous experience on war preparedness,data sharing & management in the mobile medical service units and war preparedness depots were implemented with Management System for Mobile Medical Service Unit of Military Region,wired LAN technology and VB assembly program.The functional modules were created to satisfy the requirements of war preparedness of mobile medical service units.Results The system,when applied in mobile medical service units,could enhance the efficiency of personnel & material management.Conclusion Management System for Mobile Medical Service Unit of Military Region makes the informatized management of mobile medical units realized.
