A study was carried out 50 patients with stomach cancer received total gastrectomy after 6-12 months of operation, recovered the digestive functions by 2 methods. The evaluation of the esophagoduodenal reflux by scintigraphy. Used 99m Tc-HIDA and gamma-camera found that as a simple, physiological acceptable method and could be used for quantitative analysis. The method of the esophago-intestinal anastomosis type omega after the total gastrectomy can remainly cause the reflux. The method of making the pseudo stomach type lygidakis with distance of 40 cm from the anastomosis stoma Roux -en-Y to the anastomosis stoma of the esophagointestine found that it can prevent the esophagoduodenal reflux. The reflux found that did not occure in all 31 patients who evaluted by scintigraphy.

250 patients with ages of 30-50 received the mammography in the Institute of Mother and Infant Protection and Care during 4/1998 - 4/1999. The results showed that patients came to examine because of the mechanical symptoms and X-ray (37.2%) in which 72% found having the physical lesion. The physical symptoms accounted for 62.8% of which 92% found having lesion on the X-ray. The lesion of the right breast, left breast and both breast were 44%, 56% and 40%, respectively. The lesion included fibrosis, tumor and complex lesion.

A cross-sectional survey of drug users who were selected by "snowballing" method between March 15 and May 30, 1999 in Haiphong City was conducted. Subjects (n=520: 514 males and 6 females) were interviewed and provided blood spescimens for HIV-1 antibody testing. Mean age of the subjects was 25 years, sixty-one percent (319/520) reported injecting drug. The 218 subjects (68%) were ever shared needles. The HIV-1 prevalence in Injecting Drug Users (IDUs) was 74%. Factors related to the presence of HIV antibody were sharing needles (OR: 4.12; 95%CI: 1.82-9.31), and injecting more than 31 times per month (OR: 2.37; 95%CI: 1.04-5.42). Extramarital sex within the last six months was reported by 44% of single and 24% of married IDUs. The high HIV-1 prevalence in IDUs suggests that preventive interventions for risk reductions of HIV-1 transmission are urgently needed in these populations.

CT scanner with marking 99m Tc-DTPA, with semi-solid meal can study completely the movement of food in the gastric region in the physiological condition and determine the gastric emptying times. The ability of rapid movement of the food from omega loop (t50% = 25.42 minutes) and the time of retention of the food in the false stomach in patients with total gastrectomy were the same as this in persons with the normal stomach (t50%=49.23 minutes). This accounted for the better living condition and less disorder in patients with gastric replacement by false stomach as type of Lygidakis total gastrectomy.

Studying was performed on the 149 patients with gastric epithelia glandular cancer received a radical total gastrectomy in the Army Central Hospital No 108 during 1/1/1994 - 1/1/2000. The results has shown that the survival rate within 1,2,3,4,5 years from operations for group connected with omega were 76,36%; 60%; 40%; 27,27%; 25,45%, 53,7% and 46%, respectively. There is a significant different between the survival rates of patients with the tumors T3 and T4. There is no different of the survival rate between levels of the glandular metastasis N2 and N3 and between the third phase and the fourth phase.

149 patients with gastric epithelioglandular cancer were operated for the total gastrectomy in the Army Central Hospital No 108 from 1/1994 to 1/200 (male: 86; female: 63), average ages: 50, divided 2 groups according to the 2 methods of the different digestive circulation recovering. The results have shown that the rate of the tumors in the determined positions as vertical axis and perimeter of stomach the average size of the tumor, the average duration of operation and the rate of accidents were not different between two groups. The average rate of accident during operation was 6,7%, the rate of surgical complication was 18,1%.There was no death.

119 patient with the peptic cancer received the total gastrectomy, participated to a study after 6-12 months of operation, were recovered the digestive functions as 2 different methods. The results of esophageal endoscopy and biosy only allowed to determine the levels of lesion but not allow affirm that these lesions due to reflu. However, there were the close relation between the general picture according to the description of boyce and microscopic picture according to the description of Beigi I with the clinical symptoms of the reflux esophagitis. Therefore, they also can be used as a standard of diagnosis. The method of the digestive functional recovering by making the distribution bag DD type Lygidakis showed the obvious efficacy in the limitation of the esophageal mucosal lesion due to the postoperative reflux

10 batches of Japanese encephalitis vaccine (JEV) produced at (NIHE) during 1998 were investigated for antigen content. The results showed that: JE antigen content of these 10 batches was equal or slightly higher than that of the reference vaccine

A total of 190 patients were treated from 1/1995 to 5/2000. We use the classification of ATT bases on the on the clinical signs and imaging diagnosis. Basing on the conservative and operative treatment, we assessed the possibility of conservative treatment on normal and pathological kidneys. Results: 190 patients consist of 104 moderate cases, 86 severe cases. 83 cases are of right kidneys and 107 are of left kidney. 30 cases are of pathological Kidneys. 92 cases were operated Nephrectomy was 67%, the conservative treatment was 33%.

53,010 tests of RIA implemented during 1/1992- 10/1996 including 45,210 tests of HBsAg, 4,764 anti-HBs, 1,119 HBeAg, 1325 anti-HBe and 1,358 anti HBc to evaluate the frequent of HBsAg, double infection of HBV and HCV in the chronic hepatitis and the changes of markers of hepatitis B in persons carrying the chronic HBsAg. The results have shown that the frequent of the hepatitis B viral infection was very high and the double infection of HBV and HCV was common in patients with the chronic hepatitis
