METHODS： 33 constipated patients and 20 healthy volunteers were recruited for a 4-wk treatment of kiwi fruit twice daily. Response during wk 1-4 was defined as an increase in complete spontaneous bowl, motion （CSBM）≥ 1/wk. Secondary efficacy included response during wk 1-4, individual symptoms and scores of bowel habits and constipation. Responses were compared with the baseline run-in period. Colonic transit time and anorectal manometry were performed before and after treatment. RESULTS： Responder rate was 54.5% in the constipated group. The mean CSBM increased after treatment （2.2±2.6 vs 4.4± 4.6, P = 0.013）. There was also improvement in the scores for bothersomeness of constipation （P = 0.02）, and satisfaction of bowel habit （P = 0.001）, and decreased in days of laxative used （P = 0.003）. There was also improvement in transit time （P = 0.003） and rectal sensation （P 〈 0.05）. However, there was no change in the bowel symptoms or anorectal physiology in the healthy subjects. CONCLUSION： Increasing dietary fiber intake is effective in relieving chronic constipation in Chinese population.展开更多

The pathogen was isolated from diseased leaves by a tissue separation method. DNA sequencing was performed by the sequence analysis of ribosomal rDNA-ITS(Internal transcribed spacer) region, and a molecular evolutionary tree was constructed by the MEGA 4.0 software. The pathogenic fungus was classified and identified by combining morphological observation finally. The results showed that the dry blight disease in leaf tip was a new disease, which was caused by Epicoccum sorghinum, and it had a serious damage to red-fleshed kiwifruit.展开更多
