Results High purine diet is the main diet habit of the gout people, young and middle aged male prefer to alcohol. The cause of gout in young and middle aged male is drinking mass of alcohol and strenuous exercise,while old aged male is catching cold,changing weather and the use of diuretic. Young and middle aged male will first outbreak at the first metatarsophalangeal joint,involve in single joint,while old aged male at the knee and ankle,involve in two to three joints. Old aged male always go with hypertension, coronary heart disease and diabetes,the rate is significantly higher than that in young and middle aged male(P＜0.05), while the rale of hyperlipemia is similar in two groups.

The decisive influencing factor of viscosity in carboxyl-methylation was cross-linking reaction. Carboxyl-methylation was the main influencing factor of solubility and swelling capacity in modification of high content amylose starch. The structure and gelatinization property of different amylose content were analyzed with an Olympus Vanox BHS-2 multi-function optic microscope, and the results were as follows. The structure of ordinary cornstarch was different from the high amylose; gelatinization temperature and pH value of starch were affected deeply by amylose content, but had little difference between the gelatinization of high content amylose starch contained 50% and 70% amylose; pH value had much more effect than temperature on the gelatinization of high content amylose cross-linked starch. Monochloroacetic acid consumption, alcohol concentration and pH value influenced the starch carboxyl-methylation. When alcohol concentration was 60%, pH value 10, monochloroacetic acid/starch mass ratio 55%, the carboxyl-methylation of high amylose cross-linked cornstarch had the best result. With the In-Vitro digestibility model and biodegradation experiment, the digestibility and biodegradability of high amylose cornstarch and its modified starch were detected.
