[The relationship of facet orientation to intervertebral disc protrusion and lateral recess stenosis in lower lumbar spine].
To investigate the relationship of facet orientation to intervertebral disc protrusion and lateral recess stenosis in lower lumbar spine. ⋯ Stress on the lower lumbar spine leads to disc protrusion. No association is found between facet joint asymmetry and lumbar disc protrusion. The asymmetry of facet joint will influence the direction of intervertebral disc protrusion at level from L(4) - S(1). The patient whose lower lumbar spine inter-facet angle may unlikely suffer from degenerative lumbar lateral recess stenosis.

[Treatment of atrial fibrillation using maze procedure by radiofrequency ablation].
From May 1994 to May 1996, 20 cases of atrial fibrillation were treated by means of Maze procedure by radiofrequenncy ablation, at the same time 19 cases of these patients were complicated with rheumatic heart valve disease and valve replacement operations were perfomned, in the other case atrial septal defect was repaired. Yoshio Kosakai's operation route was adopted in radiofrequency ablation procedure. ⋯ Short time was needed in radiofrequency ablation Maze procedure, average time increase of aortic clamping was 20.5 minutes, and there was no danger of hemorrhage related to this kinds of Maze procedure. During 7-10 days after operation, there appeared superventricular arrhythmia which might be related to ill-distribution of radiofrequency ablation, and interference of atrial electric activity.

We retrospectively analysed clinical data of 830 patients with extrahepatic biliary carcinomas treated in our hospital from 1956 to 1995. Among them, 601 had gallbladder carcinomas, and 229 cholangiocarcinomas. The results showed that extrahepatic bile duct carcinoma accounted for 6.77% of bile duct diseases. ⋯ The sex ratio (male:female) was 1:2. 54 and 1. 46:1. The operation rate and resection rate were 65.1% and 29.4% in gallbladder carcinoma while 66.4% and 20.4% in cholangiocarcinoma. The incidence rate and resection rate of extrahepatic biliary carcinomas were elevated.

Comparative Study[Limb salvage and amputation in osteosarcoma: report of 31 cases].
Three different types of operation were performed in 31 osteosarcoma patients, and some cases received chemotherapy. It revealed, wide resection of tumor supplemented with chemotherapy improved the survival and limb salvage rate enormously. ⋯ The life of prosthesis was long and most patients were satisfied with it. Chemotherapy and limb salvage can enhance the survival and life quality in patients with osteosarcoma.
