METHODS: A systematic literature search was conducted using Pub Med and EMBASE. Supplementary literature searches included screening reference lists from relevant studies and reviews. Eligible outcomes were stool wet and dry weight, percentage water in stools, stool frequency and consistency, and total transit time. Weighted regression analyses generated mean change(± SD) in these measures per g/d of dietary fiber. RESULTS: Sixty-five intervention studies among generally healthy populations were identified. A quantitative examination of the effects of non-wheat sources of intact cereal dietary fibers was not possible due to an insufficient number of studies. Weighted regression analyses demonstrated that each extra g/d of wheat fiber increased total stool weight by 3.7 ± 0.09 g/d(P < 0.0001; 95%CI: 3.50-3.84), dry stool weight by 0.75 ± 0.03 g/d(P < 0.0001; 95%CI: 0.69-0.82), and stool frequency by 0.004 ± 0.002 times/d(P = 0.0346; 95%CI: 0.0003-0.0078). Transittime decreased by 0.78 ± 0.13 h per additional g/d(P < 0.0001; 95%CI: 0.53-1.04) of wheat fiber among those with an initial transit time greater than 48 h.CONCLUSION: Wheat dietary fiber, and predominately wheat bran dietary fiber, improves measures of bowel function.展开更多

METHODS: Four hundred and fifty-seven soldiers who were assigned to specified services and 471 soldiers who were assigned to routine services were enrolled using cluster sampling, with the latter as a control group. They were surveyed using the Rome Ⅲ FBD standard questionnaire. The FBD symptom question-naire included FBD-related symptoms, severity, dura- tion or attack time, and accompanying symptoms. RESULTS: The morbidity of the military stress group (14.6%) was significantly higher than in the control group (9.98%) ( 2 = 4.585, P < 0.05). The incidence of smoking, abdominal pain and acid regurgitation ( 2 = 4.761, P < 0.05) as well as the ZUNG anxiety/depression scores ( 2 = 7.982, P < 0.01) were also sig- nificantly higher in the military stress group compared with the control group. ZUNG anxiety ( 2 = 11.523, P < 0.01) and depression ( 2 = 5.149, P < 0.05) scores were higher in the FBD group compared with the non-FBD group. The differences in the ZUNG self-rated anxiety and depression scales between the 2 groups were statistically significant ( 2 = 14.482, P < 0.01 and 2 = 6.176, P < 0.05). CONCLUSION: The morbidity of FBD was higher under military stress conditions.展开更多

METHODS： Twenty-two IBS patients selected according to the Rome II criteria （F 15, M 7; mean age 29.3±6.8, range 22-44 years） were examined. The study was blind, randomized and placebo-controlled with a crossover design. Anorectal manometry and rectal balloon distension test were performed before and after the administration of placebo and sumatriptan. RESULTS： The administration of sumatriptan caused a significant increase in the resting anal canal pressure from 9.2±2.0 kPa to 13.1±3.3 kPa （P〈0.0001） connected with the increase in the anal sphincter length and high pressure zone. After sumatriptan injection a remarkable increase in the threshold for the first sensation from 27±9 mL to 34±12 mL （P〈0.05） and urge sensation from 61±19 mL to 68±18 mL （P〈0.01） was observed. Sumatriptan did not affect either the volume evoking the rectoanal inhibitory reflex or the results of the straining test. CONCLUSION： 5-HT1 receptors participate in the regulation of anorectal function. Elucidation of the role of 5-HT1 receptors in the pathophysiological mechanisms of IBS may have some therapeutic implications.展开更多

Knowledge on this issue has increased considerably in the last decade, and it is our intention to review and summarize it in the present work. We describe a problematic that comprises physiopathological uncertainties, diagnostic difficulties, as IBS-like symptoms are very similar to those produced by an inflammatory flare, and the necessity of appropriate management of these patients, who, although in remission, have impaired quality of life. Ultimately, from almost a philosophical point of view, the presence of IBS-like symptoms in IBD patients in remission supposes a challenge to the traditional functional-organic dichotomy, suggesting the need for a change of paradigm.展开更多

METHODS: Patients who satisfied the Rome Ⅲ criteria for FBD (retrospective diagnosis) were followed up by telephone interview and/or outpatient review at 5 years after their first attendance. The patients were divided into the following groups: irritable bowel syndrome, functional abdominal bloating, functional constipation, functional diarrhea and unspecified FBD. The survival of the FBD patients overall and of those with each FBD were compared with data obtained from the Guangzhou population in 2005. The incidences of colonic cancer overall and for each FBD were compared with data from the Chinese population obtained from 56 cancer registries in 19 provinces of the country in 2008. RESULTS: Two hundred and sixty-three patients were followed-up. Five patients died, which was not significantly different from the expected survival rate. No differences in mortality among the FBDs were found. There were nine cases of organic bowel disease: three colonic cancers and six colonic polyps. The incidence of colonic cancer in FBD patients was higher than that in the general Chinese population (0.23% vs 0.03%, P < 0.05). There were significant differences in the incidence of colonic cancer among the FBDs (0/134, 0/24, 2/29, 1/66, 0/10, respectively, P<0.05); functional constipation was the most common. The incidence of colonic polyps was similar among the FBDs. The baseline age of patients who died was greater than that of those who survived (66.60±6.84 years vs 45.14±10.34 years, P<0.05). The baseline age of patients who had colonic cancer or polyps during follow-up was greater than that of those without colonic cancer or polyps (60.33±1.53 years vs 45.38±10.62 years; 54.50±6.47 years vs 45.34±10.68 years, P<0.05). CONCLUSION: FBDs do not increase the risk of death. The incidence of colonic cancer in patients with FBDs may be increased, especially in those with functional constipation and in the elderly.展开更多
Inflammatory bowel disease(IBD) is a serious health concern among western societies. The disease is also on the rise in some East Asian countries and in Australia. Health professionals and dietitians around the world ...Inflammatory bowel disease(IBD) is a serious health concern among western societies. The disease is also on the rise in some East Asian countries and in Australia. Health professionals and dietitians around the world are facing an unprecedented challenge to prevent and control the increasing prevalence of IBD. The current therapeutic strategy that includes drugs and biological treatments is inefficient and are associated with adverse health consequences. In this context, the use of natural products is gaining worldwide attention. In vivo studies and clinical evidence suggest that wellplanned dietary regimens with specific nutrients can alleviate gastrointestinal inflammation by modulating inflammatory cytokines, such as tumor necrosis factor α(TNF-α), interleukin 1(IL-1), IL-6, IL-1β, and IL-10. Alternatively, the avoidance of high-fat and highcarbohydrate diets is regarded as an effective tool to eliminate the causes of IBD. Many functional foods and bioactive components have received attention for showing strong therapeutic effects against IBD. Both animal and human studies suggest that bioactive functional foods can ameliorate IBD by downregulating the pro-inflammatory signaling pathways, such as nuclear factor κB, STAT1, STAT6, and pro-inflammatory cytokines, including IL-1β, IL-4, IL-6, COX-2, TNF-α, and interferon γ. Therefore, functional foods and diets have the potential to alleviate IBD by modulating the underlying pathogenic mechanisms. Future comprehensive studies are needed to corroborate the potential roles of functional foods and diets in the prevention and control of IBD.展开更多

Methods: FC was determined simultaneously by FEIA and an ELISA kit in 26 patients with functional bowel disease and 77 patients with IBD. We compared the difference of FC levels between patients with IBD and patients with functional bowel disease. Receiver operating characteristics curve (ROC) was constructed to obtain the optimal cut-off value of FC for distinguishing IBD from functional bowel disease and the corresponding sensitivity and specificity. Results: The median FC levels of patients with IBD in clinical active stage or clinical remission stage was significantly higher than that of patients with functional bowel disease. The median FC levels of patients with IBD in clinical active stage, IBD in clinical remission stage and functional bowel disease were as follow: 699.91 (346.14 ~ 1647.54) μg/g;407.36 (121.81 ~ 878.48) μg/g;39.04 (12.09 ~ 81.04) μg/g when FC was measured by FEIA. The median FC levels were 716.99 (240.42 ~ 1232.53) μg/g;338.46 (53.08 ~ 692.82) μg/g;41.44 (11.77 ~ 73.19) μg/g among such above three groups of patients respectively, when FC was measured by ELISA kit. The diagnostic value of IBD with FC determined by FEIA (optimal cut-off = 131.79 μg/g) and ELISA kit (optimal cut-off = 121.85 μg/g) presented an area under the curve of 0.881 and 0.873, respectively. Conclusions: FC determined by FEIA was an accurate surrogate marker to distinguish IBD from functional bowel disease.展开更多

Methods: The study took the form of a self-administered questionnaire survey, utilizing the Sexuality Satisfaction Index for IBD (SEXSI-IBD) for measuring sexuality and the Survey of Family Environment Survey of Family Environment (SFE) for measuring family functioning. SEXSI-IBD consists of 28 items and five domains, and SFE consists of 30 items and five domains. The participants were recruited at 15 self-help groups and 14 hospitals. Results: Of 146 participants, 48.6% were male and 52.4% female, with an average age of 41.1 years. A significant correlation was observed between the item average score of SEXSI-IBD and Overall Satisfaction Score (OSS) of SFE. Significant correlations were observed in two domains of the SEXSI-IBD, “Daily interaction” and “Sexual communication,” and in all five domains of the SFE. In particular, for “Daily interaction,” the strongest correlation was observed in the SFE’s “Macro system” and “Family internal environment system.” A correlation was observed between the “Physical contact importance” in SEXSI-IBD and the “Macro system” in the OSS of the SFE. Conclusions: Sexuality correlates with family functioning not only in the family internal environment system but also in the family external environment system. Through an approach aimed at elevating the degree of satisfaction for sexuality, it becomes possible to improve family functioning and realize a sense of family well-being.展开更多

There are many risk factors of FD-IBS. Mental illness of FD-IBS patients is more serious. Functional dyspepsia and irritable bowel syndrome have some similarities in the aspects of pathophysiology, pathogenesis, and treatment. We should pay attention to two aspects of the treatment of overlap syndrome, one is simplifying medications, the other is using gastrointestinal motility drug with bidirectional regulative function when necessary. Traditional Chinese medicine in this respect shows some advantages. This review addresses the epidemiology, risk factors, clinical features, pathogenesis and management of FD-IBS.展开更多

文摘AIM: To comprehensively review and quantitatively summarize results from intervention studies that examined the effects of intact cereal dietary fiber on parameters of bowel function. METHODS: A systematic literature search was conducted using Pub Med and EMBASE. Supplementary literature searches included screening reference lists from relevant studies and reviews. Eligible outcomes were stool wet and dry weight, percentage water in stools, stool frequency and consistency, and total transit time. Weighted regression analyses generated mean change(± SD) in these measures per g/d of dietary fiber. RESULTS: Sixty-five intervention studies among generally healthy populations were identified. A quantitative examination of the effects of non-wheat sources of intact cereal dietary fibers was not possible due to an insufficient number of studies. Weighted regression analyses demonstrated that each extra g/d of wheat fiber increased total stool weight by 3.7 ± 0.09 g/d(P < 0.0001; 95%CI: 3.50-3.84), dry stool weight by 0.75 ± 0.03 g/d(P < 0.0001; 95%CI: 0.69-0.82), and stool frequency by 0.004 ± 0.002 times/d(P = 0.0346; 95%CI: 0.0003-0.0078). Transittime decreased by 0.78 ± 0.13 h per additional g/d(P < 0.0001; 95%CI: 0.53-1.04) of wheat fiber among those with an initial transit time greater than 48 h.CONCLUSION: Wheat dietary fiber, and predominately wheat bran dietary fiber, improves measures of bowel function.

文摘AIM: To determine the mortality associated with functional bowel disorders (FBDs) and their possible relationship with organic bowel disease. METHODS: Patients who satisfied the Rome Ⅲ criteria for FBD (retrospective diagnosis) were followed up by telephone interview and/or outpatient review at 5 years after their first attendance. The patients were divided into the following groups: irritable bowel syndrome, functional abdominal bloating, functional constipation, functional diarrhea and unspecified FBD. The survival of the FBD patients overall and of those with each FBD were compared with data obtained from the Guangzhou population in 2005. The incidences of colonic cancer overall and for each FBD were compared with data from the Chinese population obtained from 56 cancer registries in 19 provinces of the country in 2008. RESULTS: Two hundred and sixty-three patients were followed-up. Five patients died, which was not significantly different from the expected survival rate. No differences in mortality among the FBDs were found. There were nine cases of organic bowel disease: three colonic cancers and six colonic polyps. The incidence of colonic cancer in FBD patients was higher than that in the general Chinese population (0.23% vs 0.03%, P < 0.05). There were significant differences in the incidence of colonic cancer among the FBDs (0/134, 0/24, 2/29, 1/66, 0/10, respectively, P<0.05); functional constipation was the most common. The incidence of colonic polyps was similar among the FBDs. The baseline age of patients who died was greater than that of those who survived (66.60±6.84 years vs 45.14±10.34 years, P<0.05). The baseline age of patients who had colonic cancer or polyps during follow-up was greater than that of those without colonic cancer or polyps (60.33±1.53 years vs 45.38±10.62 years; 54.50±6.47 years vs 45.34±10.68 years, P<0.05). CONCLUSION: FBDs do not increase the risk of death. The incidence of colonic cancer in patients with FBDs may be increased, especially in those with functional constipation and in the elderly.

文摘Inflammatory bowel disease(IBD) is a serious health concern among western societies. The disease is also on the rise in some East Asian countries and in Australia. Health professionals and dietitians around the world are facing an unprecedented challenge to prevent and control the increasing prevalence of IBD. The current therapeutic strategy that includes drugs and biological treatments is inefficient and are associated with adverse health consequences. In this context, the use of natural products is gaining worldwide attention. In vivo studies and clinical evidence suggest that wellplanned dietary regimens with specific nutrients can alleviate gastrointestinal inflammation by modulating inflammatory cytokines, such as tumor necrosis factor α(TNF-α), interleukin 1(IL-1), IL-6, IL-1β, and IL-10. Alternatively, the avoidance of high-fat and highcarbohydrate diets is regarded as an effective tool to eliminate the causes of IBD. Many functional foods and bioactive components have received attention for showing strong therapeutic effects against IBD. Both animal and human studies suggest that bioactive functional foods can ameliorate IBD by downregulating the pro-inflammatory signaling pathways, such as nuclear factor κB, STAT1, STAT6, and pro-inflammatory cytokines, including IL-1β, IL-4, IL-6, COX-2, TNF-α, and interferon γ. Therefore, functional foods and diets have the potential to alleviate IBD by modulating the underlying pathogenic mechanisms. Future comprehensive studies are needed to corroborate the potential roles of functional foods and diets in the prevention and control of IBD.
文摘Aims: To investigate the diagnostic value of fecal calprotectin (FC) determined by a new immunofluorescence assay-fluorescence enzyme immunoassay (FEIA) in patient with inflammatory bowel disease (IBD) or functional bowel disease, compared with the typical ELISA kit. Methods: FC was determined simultaneously by FEIA and an ELISA kit in 26 patients with functional bowel disease and 77 patients with IBD. We compared the difference of FC levels between patients with IBD and patients with functional bowel disease. Receiver operating characteristics curve (ROC) was constructed to obtain the optimal cut-off value of FC for distinguishing IBD from functional bowel disease and the corresponding sensitivity and specificity. Results: The median FC levels of patients with IBD in clinical active stage or clinical remission stage was significantly higher than that of patients with functional bowel disease. The median FC levels of patients with IBD in clinical active stage, IBD in clinical remission stage and functional bowel disease were as follow: 699.91 (346.14 ~ 1647.54) μg/g;407.36 (121.81 ~ 878.48) μg/g;39.04 (12.09 ~ 81.04) μg/g when FC was measured by FEIA. The median FC levels were 716.99 (240.42 ~ 1232.53) μg/g;338.46 (53.08 ~ 692.82) μg/g;41.44 (11.77 ~ 73.19) μg/g among such above three groups of patients respectively, when FC was measured by ELISA kit. The diagnostic value of IBD with FC determined by FEIA (optimal cut-off = 131.79 μg/g) and ELISA kit (optimal cut-off = 121.85 μg/g) presented an area under the curve of 0.881 and 0.873, respectively. Conclusions: FC determined by FEIA was an accurate surrogate marker to distinguish IBD from functional bowel disease.
文摘Purpose: The objective of this study was to examine the correlation between the sexuality of patients with Inflammatory Bowel Disease and family functioning. Methods: The study took the form of a self-administered questionnaire survey, utilizing the Sexuality Satisfaction Index for IBD (SEXSI-IBD) for measuring sexuality and the Survey of Family Environment Survey of Family Environment (SFE) for measuring family functioning. SEXSI-IBD consists of 28 items and five domains, and SFE consists of 30 items and five domains. The participants were recruited at 15 self-help groups and 14 hospitals. Results: Of 146 participants, 48.6% were male and 52.4% female, with an average age of 41.1 years. A significant correlation was observed between the item average score of SEXSI-IBD and Overall Satisfaction Score (OSS) of SFE. Significant correlations were observed in two domains of the SEXSI-IBD, “Daily interaction” and “Sexual communication,” and in all five domains of the SFE. In particular, for “Daily interaction,” the strongest correlation was observed in the SFE’s “Macro system” and “Family internal environment system.” A correlation was observed between the “Physical contact importance” in SEXSI-IBD and the “Macro system” in the OSS of the SFE. Conclusions: Sexuality correlates with family functioning not only in the family internal environment system but also in the family external environment system. Through an approach aimed at elevating the degree of satisfaction for sexuality, it becomes possible to improve family functioning and realize a sense of family well-being.
文摘The overlap syndrome of functional dyspepsia and irritable bowel syndrome (FD-IBS) is very common and difficult to treat. There are many risk factors of FD-IBS. Mental illness of FD-IBS patients is more serious. Functional dyspepsia and irritable bowel syndrome have some similarities in the aspects of pathophysiology, pathogenesis, and treatment. We should pay attention to two aspects of the treatment of overlap syndrome, one is simplifying medications, the other is using gastrointestinal motility drug with bidirectional regulative function when necessary. Traditional Chinese medicine in this respect shows some advantages. This review addresses the epidemiology, risk factors, clinical features, pathogenesis and management of FD-IBS.
