According to the dietary standards in The Dietary Guidelines for Chinese Residents developed by the Chinese Nutrition Society,we calculate the demand of various types of agricultural products in China under the conditions of balanced diet. In comparison with the output of various types of agricultural products in China at present,we find that the output of most of agricultural products in China has exceeded the reasonable demand of the Chinese residents under the conditions of balanced diet. Therefore,adjusting the agricultural production structure in China and advocating balanced diet has become an important way to solve the problem of balance between supply and demand of agricultural products.展开更多

Diagnosis of CFS was determined by conventional medicine criteria(CDC criteria for CFS), physical examination, and routine laboratory tests. TCM diagnosis of CFS relied on Four Examination Methods and Eight Principal Patterns. They were diagnosed as Ganyu Qizhi (liver and qi stagnation) and Pixu Qiruo (spleen and qi deficiency). The treatment method is to disperse the liver and facilitate qi, rehabilitate the spleen and strengthen qi (Shugan Liqi, Jianpi Yiqi). The result of the treatment indicated that the total effective rate was 100% in terms of fatigue, difficulty concentrating, headache, sore throat, muscle pain, joint aches, feverishness, rapid pulse, insomnia, depression, irregular menses, abdominal cramps, and night sweats. The percentages of specific symptoms of CFS in the patients were comparable to the conventional medical record (Table 1).展开更多
