To prevent alkaline reflux gastritis after subtotal gastrectomy with billroth' s gastroenteiostomy to reconsruict PAFPG was performed in the fist department of surgery. Twenty cases were operated with PAFPG to treat gastroduodenum ulcer and other nonmatignant gastritis, the early result is good.

TPN can not only improve the malnutrition of organism resulted from ma- lignant tumour,but also slimulate the growth of tumour.Therefore,how to make best advantages of TPN is of great concern. From July1 994to December1 995 ,we treat- ed73patietns with malignant tumour in di- gestive tract by applying TPN,and achieved very good curative effects. We sum up our experience as following:1 perioperation and chemotherapy is a good indication oTPN which can reduce post- operation com- plication and enhance effect of chemothera- py;2 Itis contraindication of TPN to termi- nal cancer patients without operation and chemotherapy patients,TPN support is helpless;3 Operation and chemotherapy may aggravate the patients stress and cause a high matabolic rate in organism,so application of TPN should stick to the prin- ciples of metabolic support;4Taking Glu- tamine(GLN) and Se will benefit the treat- ment of tumour;5 It amy be helpful to check the growth of tumour by increasing fat emulsion,decreasing or increasing cer- tain amino acid. The questions mentioned above need futher study.

Purpose: To evaluate the effect of radiotherapy and to detect the prognostic factors for residual and recurrent foci after surgery of thyroid gland cancers. Materials and Methods: 109 patients with residual or recurrent foci of thyroid cancers after surgery were treated with radiotherapy. Results:The overall 5-,10-, 15-, 20- and 25- year survival rates were 93.6%, 91.7% , 88.7%, 87.6% and 87.6% and the 5-, 10-, 15-, 20- and 25- year survival rates with no evidence of disease were 90.8%, 89.8% ,85.6%, 84.1% and 84.1%, respectively. The clinical stage was the main factor and patient's age at diagnosis, patient's sex, histopathological types and radiation dose were also the prognostic factors. Conclusion:Radiotherapy is beneficial to residual and recurrent foci after surgery of thyroid cancer. The optimum radiation dose is 45～65 Gy.
