This paper described a method for detemination of vitamin E and carotene by means of an improved method. The extract of the sample was made without passing N2, sheltering from light, and saponification. Therecovery rates of vitamin E and carotene are 97.2% and 97.6% respectively. The standard deviation is within 0.044 and 0.026.

Pulse contour cardiac output (PiCCO) monitoring is a new type of invasive hemodynamic monitoring technology, which is more and more often applied in perioperative period and the patients suffering from multiple injuries, septic shock, and extensive burn. With PiCCO one is able to monitor patients' hemodynamic indexes safely, timely, accurately, and continuously to provide reference for judgment of patients' condition and proper quality and quantity of fluid administration. This technique has a good prospect in clinical application.

Results obtained from current studies showed that the vitamin C (VC) content in Rose roxburghii Tratt was higher, about 1664-2601 mg/100g fresh sample, than all the fruits and vagetables. Vitamin E(VE) ranged from 2.4 to 3.6mg/100g sample was also higher than any other fruits and vegetables.After the wild plants were domestricated for 2 years, its VC content increased about 26%, Sugar increased 50%, tannin, however, decreased approximately 50%.
