Characteristics and trends in incidence of inflammatory bowel disease in Taiwanese children. 总被引:1,自引:0,他引:1
Cheng-Hsien Tsai Huey-Ling Chen Yen-Hsuan Ni Hong-Yuan Hsu Yung-Ming Jeng Chi-Jeng Chang Mei-Hwei Chang 《台湾医志》2004,103(9):685-691
BACKGROUND AND PURPOSE: Although chronic inflammatory bowel disease (IBD) is rare in Asian children, increasing numbers of pediatric patients with chronic IBD worldwide have been noted in recent years. This study was conducted to delineate the trend in incidence and clinical patterns of childhood IBD in Taiwan. METHODS: All children admitted to National Taiwan University Hospital (NTUH) between 1979 and 2000 who met the criteria for IBD, Crohn's disease (CD), ulcerative colitis (UC), probable CD (PCD), or indeterminate colitis were included. The clinical features and outcomes were analyzed retrospectively. Incidence was calculated using cases of chronic diarrhea during the same period of time as the risk population. RESULTS: IBD was diagnosed in 17 children (9 females and 8 males, aged 2 months to 18 years) during the study period. Six (35%) of these children had UC, 9 (53%) had CD, and 2 (12%) had PCD. The cumulative incidence of CD during 1979-1995 was 0.85%, and increased to 2.6% during 1996-2000 (p < 0.001), while the incidence of UC did not change significantly between these periods (from 0.85% to 0.99%, p = 0.16). The median interval from onset to diagnosis was 7.7 months. Eighty percent of patients had moderate to severe disease activity at diagnosis. The follow-up duration ranged from less than 1 year to 20 years, with a mean of 4.3 years. Two patients were lost to follow-up. Eighty six percent of patients responded to treatment, and 80% of patients had inactive to mild disease activity when re-evaluated at the end of 2000. CONCLUSION: There has been a marked recent increase in the incidence of childhood CD in Taiwan but the rate of childhood UC has remained unchanged. Eighty percent of cases of childhood IBD responded well to treatment. 相似文献

Robotic milling has broad application prospects in many processing fields. However, the milling performance of a robot in a certain posture, such as in face milling or grooving tasks, is extremely sensitive to process parameters due to the influence of the serial structure of the robot system. Improper process parameters are prone to produce machining defects such as low surface quality. These deficiencies substantially decrease the further application development of robotic milling. Therefore, this paper selected a certain posture and carried out the robotic flat-end milling experiments on a 7075-T651 high-strength aeronautical aluminum alloy under dry conditions. Milling load, surface quality and vibration were selected to assess the influence of process parameters like milling depth, spindle speed and feed rate on the milling performance. Most notably, the contribution ratio based on the analysis of variance (ANOVA) was introduced to statistically investigate the relation between parameters and milling performance. The obtained results show that milling depth is highly significant in milling load, which had a contribution ratio of 69.25%. Milling depth is also highly significant in vibration, which had a contribution ratio of 51.41% in the X direction, 41.42% in the Y direction and 75.97% in the Z direction. Moreover, the spindle speed is highly significant in surface roughness, which had a contribution ratio of 48.02%. This present study aims to quantitatively evaluate the influence of key process parameters on robotic milling performance, which helps to select reasonable milling parameters and improve the milling performance of the robot system. It is beneficial to give full play to the advantages of robots and present more possibilities of robot applications in machining and manufacturing. 相似文献
