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 investigate the effects of Qinma Formula on endogenous anti-inflammatory system in rats with chronic obstructive pulmonary disease (COPD); To discuss its mechanism of action. Methods Rat models of COPD were made by modified smoked lipopolysaccharide method. 70 healthy SPF male Wistar rats were randomly divided into normal group, model group, Western medicine control group (aminophylline group), TCM medicine control group (Liujunzi Decoction group) and Qinma Formula high-, medium-, and low-dose groups, with 10 rats in each group. Each medication group was given relevant medicine for gavage. The pathological changes of lung tissue were observed under light microscope; the alveolar lavage fluid (BALF) and venous blood were collected and the related indexes were tested; the levels of serum IL-1β, IL-6 and IL-10 were detected by ELISA. Results Compared with normal group, BALF white blood cells, neutrophils, macrophages, lymphocyte, hemoglobin and platelet count in rats of model group increased significantly (P<0.05). Compared with the model group, BALF white blood cells, neutrophils, and macrophages in rats of Qinma medium- and high-dose groups and Liujunzi Decoction group decreased significantly (P<0.05); white blood cells, hemoglobin, and platelet count in rats of Qinma medium-, high-dose groups and aminophylline group decreased significantly (P<0.05); levels of IL-1β and IL-6 in serum decreased significantly (P<0.05); level of IL-10 in serum increased significantly (P<0.05). Conclusion Qinma Formula can effectively inhibit the inflammatory response through the regulation of inflammatory response-related cytokines.

The unsatisfactory operation of the existing mechanism for resolving medical disputes by doctors and patients may be contributed to the instability of this mechanism, as lack of regulation constraints results in huge discrepancies of outcomes between identical cases. Specifically, the uncertainty for doctor-patient consultation in the guidelines, evaluation and decision mechanism,consultation process, and compensation calculation. In this consideration, it is recommended to elevate the mechanism stability of this consultation by means of uniform guidelines, third-party evaluation and decision, standardized consultation process, and unified compensation standard.
