Objective To explore the effect of dietary categories on effectiveness of the intestinal cleanliness before the colonoscopy,patients' acceptance of dietary changes and adverse reactions in bowel preparation.Methods Totals of 94 patients who underwent colonoscopy were divided into normal diet group (n =30),semi-liquid food group (n =32) and fasting group (n =32) according to the dinner diet styles the day before the colonoscopy.Observed three groups of adverse reactions,patients' acceptance and intestinal cleanliness.Results No significant difference was found in the medicine dosage,water intake,intestinal cleanliness among the three groups (P ＞ 0.05).The cases of fatigue phenomenon and discomfort on dietary changes in normal diet group were 4 and 1,in semi-liquid food group were 14 and 8,in fasting group were 13 and 5,and the difference was statistically significant (x2 =7.765,20.623,respectively; P ＜ 0.05).While no significant difference was found in the incidence of other adverse reaction among the three groups (P ＞ 0.05).Conclusions Dietary categories are no effect on the intestinal cleanliness of the colonoscopy.However,according to the conditions of the patients before taking laxatives poly would increase their comfort under certain dietary restrictions.

Objective::To deeply understand important scientific problems and key technical problems in the cultivation of Chuanxiong, the Chuanxiong cultivation situation of 247 households in 23 towns of 5 counties in Sichuan province were investigated, providing basic data for the standardized cultivation of Chuanxiong. Method::On the basis of reported literatures, a questionnaire survey was conducted on the farmers of cultivating Chuanxiong in main producing areas, field measurements were also preformed, and the cultivation status of Chuanxiong was comprehensively analyzed. Result::The proportion of plain-breeding mainly existed in Pengzhou and Shifang, where per farmer had a small scale of planting areas, was 65%, while the proportion of mountain-breeding mainly existed in Meishan, Qionglai and Dujiangyan, where per proprietor had a large scale of planting areas, was 92%. The planting density and yield of Chuanxiong varied greatly among individuals. The growth period of Chuanxiong in Meishan and Qionglai is about 30 days shorter than that in Pengzhou, Shifang and Dujiangyan. About half of farmers applied base fertilizer and top dressing in spring. The proportion of NPK compound fertilizer input was high (>90%). Chuangxiong has a few diseases and insect pests, the incidence of which in new production areas was obviously lower than that in old production areas. The application of herbicide was not standardized. 52% farmers used Chu cao ling No.1 which was made by agricultural material store owners. The labor cost accounted for the highest proportion (37%) in Chuanxiong cultivation. Conclusion::Now in Sichuan clonal propagated patterns of Chuanxiong were both mountain-breeding and plain-breeding. It is suggested to make clear the differences between mountain-breeding nodes and plain-breeding nodes, and breed high qualities of Chuanxiong nodes. The mechanization research and production of Chuanxiong should be promoted, realizing timely planting and harvesting. Farmers should be guided to increase the application of organic fertilizer, and meanwhile standardize the application of agrochemicals.
