The absorption of 59 Fe incorporated into yeast was studied in rats. Yeast was cultured in a nutrient solution to which radioactive 59Fe was added as an intrinsic tag. The 59Fe-enriched yeast was separated from the solution by centrifuge and given to rats by a stomach tube. The rats of the control groups were given the radioactive " Fe together -with ordina-ly yeast plus ferrous sulfate or only with ferrous sulfate separately.All feces were collected until less than 0.5 per cent of the administered dose was present in a 24-hour specimen of feces. The radioactivity in the feces was then measured daily for three successive days. The absorption of iron was calculated by the difference between intake and fecal loss.The result revealed that the absorption of iron in "Fe-enriched yeast (38.7%) was similar to that of ferrous sulfate (38.3%). It indicated that the iron incorporated into yeast was easily to be absorbed.This study afforded the scientific data for researching and popularizing fortified food with iron-enriched yeast.

Objective To evaluate the attitudes of clinical nurses toward caring for the dying patients, and possible influencing factors concerning the attitudes were investigated, so as to provide a scientific basis for further intervention, thus improving the positive attitudes toward care of the dying patients in the future research. Methods A convenience sampling method was used to recruit 770 nurses from 15 hospitals located in 5 provinces in China. A demographic survey, Chinese version of Frommelt Attitudes Toward Care of the Dying Scale Form B (FATCOD-B-C) and Chinese version Death Attitude Profile-Revised were employed in the survey. Results FATCOD-B-C scale was used to evaluate the attitudes of nurses toward caring for dying patients, with the mean score of all FATCOD-B-C item being 95.62 ± 7.45. To analyze relationship among demographic variables and the total score of FATCOD-B-C. Univariate analysis revealed that age group (F=2.285), years employed as a nurse (F=3.353), educational background (F=5.581), technical title (F=5.692), level of hospital (t=2.058), religious beliefs (t=-2.788), previous education on death and dying(F=9.743), previous experience in dealing with terminally ill persons (t=2.761) had significant influence on the nurses' attitudes toward caring for dying patients and families(P<0.05). Multiple linear regression analysis indicated that nurses' attitudes toward caring for dying patients had been affected by those factors, among which the most influential factor was educational background. Conclusions It shows that nurses'FATCOD-B-C scores are at a low level. It is suggested to improve nurses' positive attitudes of caring for dying patients and their families by making the specific methods based on the influencing factors, thus improving the development of palliative care.

Saussurea medusa is a rare traditional Chinese medicinal herb. Besides anti-inflammatory and analgesic activities, it has effects of disinhibiting cold, dispelling dampness and promoting blood circulation. Flavonoids are the main medicinal compounds in S. medusa. Contents of flavonoids and expression of flavonoids biosynthesis related genes in white and red (induced by low temperature, high sucrose and high light) callus were analyzed. The results showed that the total flavone in red line was 3.60 times higher compared to white line. The accumulation of rutin in red line (0.25% of dry weight) was 2.40 times higher compared to white line. Anthocyanins were abundant in red line, with the contents of cyanidin 3-O-glucosidechloride and cyanidin 3-O-succinyl glycoside 0.12% and 0.19% of dry weight respectively. CHS, F3'H, FNS, FLS, DFR and ANS genes were highly expressed in red line compared to white line. Expression of three transcription factors (MYB, bHLH and WD40) in red line was significantly higher than that in white line, especially the expression of MYB (19.70 times higher compared to white line). These results indicated that high expression levels of transcription factors induced high expression of structural genes in red line, thereby enhancing the flavonoids biosynthesis. The expression of bHLH and WD40 was similar, whereas it was significantly different from that of MYB, indicating that bHLH and WD40 could form a binary complex to regulate expression of structural genes and flavonoids biosynthesis.
