Objective: To evaluate the effect of concomitant chemoradiotherapy for the prevention of recurrence and metastasis of postoperative salivary adenoid cystic carcinoma(SACC).Methods: 14 cases of salivary adenoid cystic carcinoma after operation were treated with concomitant chemoradiotherapy. Regular radiotherapy of 60 Gy and chemotherapy with hydroxycamptothecin (HCPT) at 10 mg/m 2 , 3 times a week, were administered. HCPT was given in 1st, 2nd, 4th and 5th week. Recurrence and metastasis of SACC after operation were observed using CT, MRI, ultrasonography and X ray. Results: After 3～17 months' follow up, relapse free survival was 100%. No recurrence and metastasis of SACC after operation were found. Adverse reactions of the chemotherapy were nausea, vomiting and leukopenia. After suspended in a short time and using ondansetron and /or G CSF the chemotherapy of HCPT was continued and completed. Conclusion: concomitant chemoradiotherapy of HCPT and radiotherapy can prevent recurrence and metastasis of SACC after operation. The efficacy of long term needs further observation.

Objective:To study the specific photochemical effects of a newly designed target photosensitizer. Methods Based on the technique of antisense nucleic acid and the principle of photochemical reaction effects,a specific sensitizer,TFO P has been designed and synthesized.When in coordination with long wave ultraviolet ray(UVA) ,this decorated complex (TFO P) was added into the blood cell suspension to inactivate the contaminating virus( duck hepatitis virus B,DHBV).The efficacy of specific binding to DHBV DNA and viral inactivation by TFO P was detected by gel shift blot assay and infection of primary culture of duck hepatocyte.Results The designed TFO P could specifically bind to different DHBV DNA line sample and present different linking level.With a TFO P concentration of 0.1 nmol/ml and UVA intensity of 1800 ?W/cm 2,the DHBV in blood cell suspension could be reduced by 1.90～5.40 logs.Conclcusion The photochemical effects of TFO P could significant inactivate DHBV in blood.

Objective To observe the photochemical effect of methylene blue (MB) on the inactivation of E. coli in blood and on biological functions of blood cells. Methods The blood was treated with 15 ?mol/L MB, 40 000 Lux halogen lamp irradiation and 0.35 mmol/l rutin for 10～40 min. The photochemical effect of MB on the inactivation of E.coli in blood was observed. The changes of biologic functions of blood cells were measured by means of RBC membrane binding to poly L lysine, reaction promoted by ATP enzyme and neutrophil phagocytosis tests. Results After treatment for 40 min, the E.coli count in blood decreased by 5 log units. The value of T/E of MB and irradiation of halogen lamp was higher than 1. No obvious changes of the morphology of blood cell were found. The negative electrical charges on membrane of RBC decreased by 11.23%～25.49%. After treatment of the blood for 20～30 min, the activity of Na + K +ATP enzyme of RBC membrane increased by 7.60%～20.07%. When the blood had been treated for 10～20 min, the positive rate of neutrophil phagocytosis enhanced by 9.00%. Conclusion MB photochemical treatment can effectively inactivate E. coli in blood. Under morphology specific condition of effectively inactivated blood bacteria, the shapes and functions of blood cells are not altered, but the RBC adhesion may increase by about 11.23%～25.49%.
