Objective To prevent the fall of community elders with therapeutic recreation. Methods 248 elders from 4 communities were divided into intervention group (n=128) and control group (n=120). The intervention group accepted therapeutic recreation for 2 months, and were surveyed balance and attention ability before and after intervention. All the elders were followed up for 12 months, and their falling were recorded. Results 190 elders completed the studies. After therapeutic recreation, the functions of audition tracing, attention span, attention persistence, balance ability of intervention groups had improved. The incidence of fall intervention groups decreased 40%～54.5%, and the events of the fall decreased 45.5%～72.2% in the intervention group, but no changes in the control. The elders feared less for falling and knew more about prevention of fall in intervention groups. Conclusion Therapeutic recreation can improve attention and balance ability, psychological status and fall prevention consciousness, decrease the events of falling of community elders.

Objective To approach the effects of combined plateau hypoxia due to high altitude and sodium cyanide(NaCN)intoxication on the heart function of rats.Methods 84 healthy male SD rats were randomly divided into 2 groups:only NaCN intoxication in plain areas(altitude 308m)(PL group)and combined high altitude(altitude 4 000m)hypoxia and NaCN intoxication(PH group).Rats in PH group were pre-treated with hypoxia for 72h in a plateau hypoxia cabin(simulating altitude 4 000m).12 rats of PH group were anesthetized.NaCN in a dosage of 3.6mg/kg was subcutaneously injected into the back of rats.At the time points of-10min,0min,10min,20min,30min,40min,50min,60min and 90min after NaCN injection,the left ventricular systolic pressure(mLVSP),+dP/dtmax and heart rate(HR)were recorded by physiological functions signal processing system RM6240.The arterial blood were taken from the other 72 rats for myocardium zymogram detection(including AST,LDH,CK,CK-MB)at the time points of 0h,0.5h,1h,2h,4h and 6h after NaCN injection.Results Compared with the PL group,the mLVSP,+dP/dtmax,and HR changed obviously(P

Objective To evaluate the effects of modulated, medium frequency electrotherapy on hemodynamics after thoracic surgery to provide non-pharmacological measures for preventing deep vein thrombosis (DVT).Methods Seventy thoracic surgery patients were divided into an experimental group and a control group. Both groups received conventional treatment and nursing. The experimental group (35 patients) was treated with modulated, medium frequency electrotherapy additionally while the control group (35 patients) was not. The vein systolic maximum velocity (Vmax), vein diastolic minimum velocity (Vmin) and time-averaged mean velocity (TAVM) in the femoral vein, the superficial femoral vein, the deep femoral vein, the popliteal vein and the anterior tibial vein were observed before the operation, 4h after the operation, just after 20 minutes of electrotherapy, 15 min after the electrotherapy and 30 min after the electrotherapy. Results There were significant differences among the time points in the experimental group. There was no significant difference among the time points in the control group.There were significant differences in lower extremity hemodynamics between the experimental group and the control group at end of the electrotherapy session, but no significant differences at the later time points. Conclusions Modulated, medium frequency electrotherapy has a significant effect on lower extremity hemodynamics. It is an effective method for DVT prophylaxis in perioperative thoracic surgical patients.
