OBJECTIVE: To study the material basis of the tonifying effect of Radix Changii by observing its contents of nutrient elements. METHODS: The contents of vitamins in Radix Changii and inorganic elements in the water extracts of it were tested by high performance liquid chromatography, fluorescence spectrophotography and scanning electron microanalysis. RESULTS: Radix Changii contains fat-soluble vitamins E and K 259.2 and 64.1 microg/kg respectively, and water-soluble vitamins C, B1 and B2 78.5, 0.6 and 0.7 mg/kg respectively. Its decoction contains abundant potassium and calcium ions. CONCLUSION: Radix Changii is rich in elements necessary for human body. It has the material basis for tonification.

Objectives:To observe the role of parenteral nutrition(PN) in the elderly postoperative patients with gastric carcinoma. Methods:Forty cases were randomly divided into two groups. One group received PN after operation as PN group and another group was supported only with the general treatment without PN as control group. Results:①The rate of postoperative complications was 15% (3/20) with no death in PN group, and it was 45%(9/20) with mortality rate of 5%(1/20) in control group. ② Between the two groups, there were very significant differences in nitrogen balance, body weight, creatinine height index(CHI), serum albumin, serum transferrin and blood urea nitrogen(BUN) at the 8th postoperative day( P
