[Objective] To investigate the effects of aerobic exercise on osteoporosis in the elderly.[Methods]Sixty elderly were divided into two groups:control group(n=30)without conscious and regular exercise and experimental group(n=30)with aerobic exercise.After 12 months,bone mineral density in lateral lumbar spine 2~4(L2~4),left side of femoral neck(L-FN),left side of greater trochanter(L-TR)and wards area were measured for by dual energy X-ray absorptiometry(DEXA)for the statistical analysis.[Results]The bone-mass-loss after the experiment was obviously lower than before;bone mineral density(BMD)of control group was lower than experimental group in the four parts.The difference(P

Objective To explore the effect and application value of percutaneous transhepatic various interventional technique for treatment of common bile duct stones.Methods 46 patients with common bile duct stones were treated.All patients were treated by percutaneous transhepatic cholangiopancreatography in order to confirm the number and location and size of the stones.Place me-chanical lithotripsy net according to the size of stones.Then percutaneous transhepatic balloon dilation.Postoperatively biliary tract was drained for 2 weeks.Results 45 operations were successful,The successful rate was 97.83%.Complete stone removal was obtained with one session in 41 patients and two sessions in 4 cases,respectively.There was no serious complications occurred during the operation. There was no perforation and bleeding,but hyperamylasemia occurred in 3 patients and acute pancreatitis occurred in 1 patient and bile perito-nitis occurred in 2 patients.Conclusion Percutaneous transhepatic various interventional technique can keep the function of papillary sphincter and is a valuable methed for patients suffering from common bile duct stones with a high successful rate and safety.
