With a spreader and improved Luque's Rod segmental fixation, operative reduction for thoraco-lumbar fracture was conducted in 60 cases of theoraco-lumbar fracture-dislocation concomitant with paraplegia. The procedure is helpful to rehabilitation exercises and the reault is satisfactory. The mechanical condition on Luque's Rod and vertebra complex and antideformity mechanism of the improved fixation has been analysed to study the merits of this new proceedure. The improved Lugue's Rod fixation was compared with the original one in the facture of thorac-lumbar spine.

A prospective study on a new antibictic antineoplastic drug Epirubicin (pharm-orubicin,EPI)in the management of malignant tumors was carried out from February 1987 to February 1990.Diseases divided into three groups, ( 1 ) 47 cases, recurrences/metastases of the initial tumor, after treatment of operation, radiation or other antineoplastic drug; (2)8 cases, after palliative operation; (3)15cases, after radical operation.The response rate was 92.9% for maligcant lymphoma. The EPI containing regimens were also effective in the patients with gastre-intestinal cancer, breast can- eer and sarcoma, etc. The main side effectsof EPI containing regimens were also analysed, and the dose-limiting toxicity was still bone marrow depression. Only one patient showed I A-V block. Tie role of EPI in chemotherapy of common malignancies was discussed

Fogarty balloon catheters have been widely used in vascular surgery, But no such products have been manufactured in China yet. The Department of Surgery of this hospital in cooperation with Chongqing Changjiang Rubber Plant has successfully developed the batch of China-made Fogarty balloon catheter, Exporime-ntswere performed on 14 dogs to investigate the acute damage to arterial and venous walls. The results indicated that the damage was slight. Therefore, we consider that the China-made Fogarty balloon catheter can be safely used in the clinic

Objective To investigate the inhibitory effect of appling slow-releasing triptolide on adventitia on the intima hyperplasia of autologous vein graft.Methods In 24 male New Zealand rabbits, external jugular vein to common carotid artery models were established, and then were divided into 3 equal groups at random: blank-control group, receiving no management on adventitia of the vein graft; F-127 control group, receiving local application of 0.5 mL of 20 % F-127 on adventitia of the vein graft; experiment group, receiving local application of 0.5 mL of 20 % F-127 containing triptolide 300?g. Vein graft specimens were harvested at 2 weeks after the operation. Histomorphologic methods were used to detect the degree of intima hyperplasia of the specimens. The expression of bcl-2 and Fas of the specimens was detected by immunohistochemistry. The apoptosis vascular smooth muscle cells (VSMC) were detected by TUNEL.Results Two weeks after vein grafting, compared to blank-control group and F-127 control group, intima hyperplasia of experiment group [intima thickness (29.9?7.6)?m, I/M 0.56?0.08] was markedly inhibited (P

Objective To review experimental study and clinical application of materials to bile duct repair and reconstruction.Methods Comparison of different materials was made between advantages and disadvantages.Results Synthetic grafts such as vitallium,teflon are easy to handle,but have no flexion,and have foreign body reaction.Although autogenous free tissues such as venous patch and peritonium are resistant to infection,they are likley to lead to bile duct stricture because of lacking adeuqate blood supply.Vascularized neibouring tissues for repearing bile duct defect have satisfactory results.Conclusions To avoid bile duct striccture,vary measures should be taken to repair bile duct defecs;for segmental loss of bile duct,end to end anastomosis or Roux-en-Y biliary jejunal reconstruction should be applied.
