Objective To detect the safe application of autoblood re-trasfusion of medical trioxyen. Methods 50 patients who received fundamental autohemotherapy with German DR.HANSLER OZONOSAN treating system were extracted 100ml venous blood,which was mixed with 100ml,10~20?g/m1 medical trioxyen and then retransfused into the patients.We observed the adverse effect during the course of treatment and measured the blood pressure and blood glucose of every patient accordingly. Results Among the 50 cases,4 (about 8%) had adverse effect after blood extracting. 5 cases (about 10%) had adverse effect after the trioxyen re-transfusion. The cardinal symptoms included:dizziness,nausea,emesia,cold sweat,blood pressure decrease,shock etc. Conclusion Before retransfusing the medical trioxyen,handling the indications,contraindications,making the patients have good sleep and diet and have necessary comunication with them can make the negative reaction lower at most.

Hypoxic cells that exist in nasopharyngeal cancer can not be killed easily and they are the underlying cause for recurrence and metastasis. In radiotherapy for nasopharyngeal cancer, the application of Qi-benefiting and blood-supplementing Chinese medicines can improve blood circulation, increase oxygenation of tumor body, and ameliorating the status of hypoxic cells. Besides medical ozone can promote oxygen-carrying ability of hemoglobin and releasing of oxygen capacity and improve oxygen supplying. If the method of radiotherapy combined with ozone and Chinese medicines can solve the problem of resistance of hypoxic cells to radiation and promote the oxygen effect in radiation and the interaction between organisms, then it will play an important role in the treatment of nasopharyngeal cancer.

Objective To investigate the feasibility of cholangioenterostomy without stent tube drainage. (Methods) In this study 52 cases anastomosed without stent tube drainage (group A) and 56 cases with stent tube drainage (control,group B) were included. The patients′course of therapy and recovery, postoperative follow-up and reoperation were compared between group A and B. Results The rate of bile leakage was (5.8)% (3/52) in group A and 3.6%(2/56) in group B, respectively ,which was not significant(P
