It is the ＂stabilizer＂ of social and economic development and the ＂buffer＂ of reform. It is of great significance and function to the construction of economic development, social progrcss and harmonious society. However, due to many factors, the operation of the social health insurance fund is facing greater risk. Although the balance is rich, but the general talk about the ＂balance＂, inevitably fall into the ＂too optimistic, ignore the risk＂ of the errors, the current basic medical insurance system, compared with working employees, retirement elderly people do not pay, personal accounts into more, The overall proportion of individual funds to pay lower policy concessions. Although there is a large amount of surplus in the annual health insurance fund, a large part of the balance is due to the relatively young age structure of the insured population and the low consumption of health insurance funds. With the increasing level of the aging of the insured population, the ratio of on-the-job and the backward is gradually reduced, the effect of these preferential policies will continue to enlarge, making the total fund expenditure increased significantly. Therefore, it is an important task to reform the basic medical insurance system in China to strengthen the research on risk control in the medical insurance fund of urban workers, to prevent and control the risks faced by the fund and to ensure the safety of the fund.展开更多

Since these activities may be correlated with the presence of antioxidant compounds, extract of carrot and carrot callus were evaluated for their anthocyanin, flavonoids and total phenolic content as well as total antioxidant activity. Anthocyanin content was measured by spectrophotometric method. Total phenols and flavonoids were analyzed according to the Folin-Ciocalteu method and total antioxidant activity was assessed by ferric reducing/antioxidant power （FRAP） assay. Anthocyanin, flavonoids and total phenolic content were estimated to be 9.36 mg%, 46.96 mg% and 57.01 mg% for callus and 6.82 mg%, 32.96 mg% and 42.69 mg% for carrot, respectively, on fresh weight basis. The total antioxidant activity for the callus and carrot was found to be 51.13 mg, 118.77 mg, 91.08 mg and 140.08 mg equivalent and 79.40 mg, 184.44 mg, 141.43 mg and 217.52 mg equivalent to gallic acid, vitamin C, butylated hydroxyanisole （BHA） and trolox, respectively, when expressed per 100 g on fresh weight basis. The antioxidant activity of fresh carrot was found to be higher compared to its callus.展开更多
