OBJECTIVE:To standardize the utilization management of medical appliance in rural medical institutions and improve the supervision efficiency.METHODS:Electronic supervision of medical appliance in rural medical institutions was performed in terms of purchase,acceptance and utilization of medical appliance using computers and health information network.RESULTS & CONCLUSIONS:The implementation of electronic management of medical appliance in rural medical institution achieved initial success to standardize purchase channel and utilization of medical appliance and improve efficiency and level of supervision.Electronic supervision is worth of popularizing in national medical institutions while it is deficient in electronic supervision network joint,matching measures and systems,etc.

This is a retrospective study of 103 cases of early gastric cancer undergoing surgery during the years of 1974-1988 with a special discussion on surgical treatment.The lesions were localized to the mu-cosal layer in 54.3%,to submucosal layer in 45.7%,In 10% of patients there was lymphnode metastasis,all of them were in the first station.Operation consisted of radical subtotal gastrectomy in 94.2%.and total gastrectomy in 5.8%.The extent of lymphatic excision was:Ro in 12.6%,R1 in 61.2% and R2 in 26.2% Postoperative chemotherapy was given in 61.2%.However no statistical difference of 5 years survival rate was found in respect to the extent of lymphatic excision as well as postoperative chemotherapy.Since 60.2% of EGC lesions were of minute,multiple and plane type,preoperattve en-doscopy and intraoperative biopsy of gastric mucosa,if necessary,should be carefully done to ascertain that no lesion was overlooked in the remnant of the stomach.Follow-up rate was 96%,and the survival rates of 3 and 5 years were 97% and 93.7%.This makes the authors believe that a radical operation of R1 is justified and routine postoperative chemotherapy is unnecessary.

In this communication, the values of serum CA-50 in a series of patients with benign and malignant GI diseases are reported. It was found that CA-50 was positive in 86.7% of 30 pancreatic cancer patients with an average level of 427.53U/ml, which was statistically different from that found in non-malignant control group. In this series serum CA-50 determination helped to confirm the diagnosis of pancreatic cancer in 6 cases, in which B-mode ultrasono-graphy failed to make a definite diagnosis, and in another 3 cases CT scanning was unable to disclose the tumor. The combination of CA-50, B-mode ultrasonography, and CT made definite diagnosis in 100% of all 30 pancreatic cancer patients. The author discussed the significance of CA-50 determination in the diagnosis and differential diagnosis of pancreatic cancer.
