RESUMO
Background:Therapeutic drug monitoring(TDM)has emerged as the important method for managing loss of response to infliximab.The effect of reactive and proactive TDM on clinical outcomes in inflammatory bowel disease(IBD)is uncertain.Aims:To evaluate the effect of proactive and reactive TDM of infliximab on the prognosis of patients with IBD.Methods:Clinical data of 99 IBD patients treated with IFX from January 2017 to October 2021 at the First Affiliated Hospital of Air Force Military Medical University were retrospectively analyzed,including 34 patients with proactive TDM and 65 patients with reactive TDM.The rate of treatment failure,IBD-related surgery or hospitalization were compared between the two groups.Logistic regression analysis was used to determine the independent risk factors of treatment failure.Results:The median follow-up of the patients was 21(13,32)months.The rate of treatment failure,IBD-related hospitalization rate of proactive TDM group were significantly lower than those of reactive TDM group(P<0.05),however,no significant difference in IBD-related surgery rate was found between two groups(P=0.081).Univariate analysis showed that ileocolonic resection before TDM,antibodies to infliximab(ATI)and reactive TDM might be correlated with treatment failure(P<0.05).Logistic regression analysis showed that reactive TDM(OR=5.829,95%CI:1.070-31.754,P=0.042)was the risk factor of treatment failure,and ileocolonic resection before TDM(OR=0.119,95%CI:0.019-0.736,P=0.022)was the protective factor of treatment failure.Conclusions:Compared with reactive TDM group,proactive TDM can significantly decrease the rate of treatment failure and IBD-related hospitalization rate.Reactive TDM is the risk factor of treatment failure,and ileocolonic resection before TDM is the protective factor of treatment failure.
RESUMO
Coronavirus disease 2019 (COVID-19) has become a worldwide pandemic. During the rapid spread time, it is a great challenge for patients with inflammatory bowel disease (IBD) who use immunosuppressive drugs from vaccination and drug application. This article is intended to supplement and revise the recommendations of the Inflammatory Bowel Disease Group of the Chinese Society of Gastroenterology in 2020 on the "Management of patients with inflammatory bowel disease during epidemic of novel coronavirus pneumonia", mainly including the treatment and vaccination of IBD patients complicated with COVID-19. It is expected to guide clinicians in drug use, vaccination of IBD patients at an appropriate time, also help patients getting through the epidemic period of COVID-19.
RESUMO
Objective:To investigate the effects of biologics on psychological status and quality of life in patients with inflammatory bowel disease (IBD).Methods:A cross-sectional survey was conducted in 42 hospitals in 22 provinces (autonomous regions and municipalities directly under the central government) from September 2021 to May 2022. General clinical information and the use of biologics were obtained from adult patients diagnosed with IBD who voluntarily participated in the study. Psychological status was evaluated using the Generalized Anxiety Disorder (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Pittsburgh Sleep Quality Index (PSQI), and Inflammatory Bowel Disease Questionnaire (IBDQ) assessment tools. Counts were analyzed via the Chi-square test, and datasets that were not normally distributed were analyzed via nonparametric tests. P<0.05 was considered statistically significant. Results:A total of 2 478 valid questionnaires were collected. The GAD-7 score of the biologics group was significantly lower than that of the non-use group [6 (2, 9) vs. 7 (3, 10), Z=-3.49, P<0.001]. IBDQ scores [183 (158, 204) vs. 178 (152, 198), Z=-4.11, P<0.001], intestinal symptom scores [61 (52, 67) vs. 58 (49, 65), Z=-5.41, P<0.001], systemic symptom scores [28 (24, 32) vs. 27 (23, 31), Z=-2.37, P=0.018], emotional ability scores [69 (58, 77) vs. 67 (56, 75), Z=-3.58, P<0.001] and social ability scores [26 (22, 29) vs. 25 (22, 29), Z=-2.52, P=0.012] in the biologics group were significantly higher than in the non-use group. GAD-7 scores [5 (2, 9) vs. 6 (3, 10), Z=-3.50, P<0.001] and PSQI scores [6 (4, 9) vs. 6 (4, 9), Z=-2.55, P=0.011] were significantly lower in the group using infliximab than in the group not using it. IBDQ scores were significantly higher in patients using vedolizumab than in those not using it [186 (159, 205) vs. 181 (155, 201), Z=-2.32, P=0.021] and were also significantly higher in the group treated with adalimumab than in the group not treated with adalimumab [187 (159, 209) vs. 181 (155, 201), Z=-2.16, P=0.030]. However, ustekinumab had no significant effect on any of the scores. Conclusion:The use of biologics is strongly associated with improvements in anxiety status and quality of life in IBD patients.
RESUMO
Objective:To compare the knowledge of endoscopic screening of gastrointestinal cancers between digestive healthcare workers and new chatbots (chatGPT and new Bing).Methods:A test with twenty-three questions of endoscopic screening of gastrointestinal cancers was conducted, focusing on the appropriate age of screening, high-risk factors, the follow-up time, and the advantages and risks of digestive endoscopy. Digestive healthcare workers were invited to complete the test through electronic questionnaires. New Bing and chatGPT were used to answer each question for 10 rounds. The primary endpoint was the correct rate of all answers. The answer accuracy between digestive healthcare workers and new chatbots were compared using variance analysis, and the factors that affected the accuracy of the answers in digestive healthcare workers were explored using univariate and multivariable liner regression analysis.Results:The results of the test completed by 76 digestive healthcare workers (21 residents, 28 digestive nurses, and 27 digestive doctors) were analyzed. The accuracies were 36.4%±10.9%, 34.5%±10.2%, 52.2%± 12.6%, 46.3%±9.8% and 67.1%±9.3% in residents, digestive nurses, digestive doctors, chatGPT, and new Bing, respectively, with significant difference ( F=22.6, P<0.001). The accuracy was highest in new Bing ( P<0.001). The accuracy was comparable between chatGPT and digestive doctors (LSD- t=-1.398, P=0.166), and both higher than that of digestive nurses (LSD- t=2.956, P=0.004; LSD- t=5.955, P<0.001) and residents (LSD- t=2.402, P=0.018; LSD- t=4.951, P<0.001). Furthermore, the accuracy was comparable between digestive nurses and residents (LSD- t=-0.574, P=0.567). Compared with new Bing, digestive doctors had lower accuracy in answering questions related to adverse events of screening, follow-up recommendation of intestinal metaplasia, high risk factors and screening methods for colon cancer ( P<0.05), but higher accuracy in answering questions related to endoscopic adverse events and screening methods for esophageal cancer ( P<0.05). Multivariable liner regression analysis showed that being digestive doctors ( β=11.7, t=3.054, P=0.003) and questionnaire response time (≥7.6 min) ( β=7.8, t=2.894, P=0.005) were independent factors for the answer accuracy of digestive healthcare workers. Conclusion:Compared with digestive healthcare workers, New chatbots—new Bing has higher accuracy in answering gastrointestinal cancer screening-related questions, but performs poorly in answering questions such as adverse events of endoscopy and screening methods for esophageal cancer.
RESUMO
Chronic atrophic gastritis (CAG) and gastric intestinal metaplasia (GIM) significantly increase the risk of gastric cancer. Blocking the development of CAG and GIM would help to decrease the incidence of gastric cancer. It was revealed that eradication of Helicobacter pylori could reverse gastric mucosa atrophy. Recent studies reported that GIM could be reversed to a certain extent. Clinical studies demonstrated that Lamb′s tripe extract and vitamin B12 capsule exhibited significant reversal effects on GIM. The present study systemically reviewed the diagnosis and treatment of CAG and clinical application of Lamb′s tripe extract and vitamin B12 capsule, and established the specialist instruction that would guide the reversal treatment of CAG and GIM.
RESUMO
Beh?et′s syndrome is a kind of chronic systemic vasculitis with involvement of multiple organs. Intestinal involvement of Beh?et′s syndrome is presently named as intestinal Beh?et′s syndrome. Recently, there is considering another kind of disease type with only typical intestinal ulcers. Since it is difficult to differentiate intestinal Beh?et′s syndrome from Crohn′s disease, intestinal tuberculosis, intestinal lymphoma, and intestinal manifestations of many other autoimmune diseases, and there is limited evidence for the therapy of intestinal Beh?et′s syndrome, proposing diagnosis and treatment recommendations for intestinal Beh?et′s syndrome through evidence-based judgment will be of great significance for clinical practice.
RESUMO
Objective:To investigate the psychology status and quality of life in patients with inflammatory bowel disease(IBD) in China, and to analyze the influencing factors.Methods:From September 2021 to May 2022, 42 hospitals in 22 provinces(autonomous regions and municipalities directly under the central government) in China, the clinical data of 2 478 IBD patients were collected, which included age, gender, weight, first visit or not, disease activity, disease course, main clinical manifestations(diarrhea, abdominal pain, hematochezia, extraintestinal manifestations), complications, treatment medication(5-aminosalicylic acid, glucocorticoids, immunosuppressive agents, and biological agents), and whether to have surgery. Anxiety, depression, sleep quality and quality of life of IBD patients were evaluated by generalized anxiety disorder-7 items, patient health questionnaire-9 items, Pittsburgh sleep quality index and inflammatory bowel disease questionnaire, and the related influencing factors were analyzed. Univariate analysis and multiple linear regression analysis were used for statistical analysis.Results:The average age of 2 478 IBD patients was 37.96 years old, and male counted for 62.43%(1 547/2 478). There were 61.82%(1 532/2 478) of the IBD patients in the active stage of disease, mostly mild or moderate(588 and 734 cases). There were 60.61%(1 502/2 478) of the IBD patients with different degrees of anxiety, 58.35%(1 446/2 478) of the IBD patients with different degrees of depression, and 48.87%(1 211/2 478) of the IBD patients had different degrees of sleep problems. The results of multiple linear regression analysis indicated that female, higher level of disease activity and longer disease course were independent risk factors of anxiety, depression and sleep quality in the IBD patients(unstandardized regression coefficient(95% confidence interval) 1.08(0.65 to 1.50), 0.45(0.23 to 0.68), 0.19(0.02 to 0.36), 0.83(0.33 to 1.32), 0.62(0.36 to 0.88), 0.28(0.08 to 0.47), 0.47(0.16 to 0.77), 0.39(0.23 to 0.55), 0.14(0.02 to 0.26); P<0.001, <0.001, =0.025 , =0.001, <0.001, =0.005, =0.003, <0.001, =0.027). The usage of biological agents was an independent protective factor of anxiety(unstandardized regression coefficient(95% confidence interval) -0.67(-1.17 to -0.17), P=0.008), and older age was an independent risk factor of sleep quality(unstandardized regression coefficient(95% confidence interval) 0.35(0.09 to 0.61), P=0.008). Higher level of disease activity, symptoms of diarrhea, abdominal pain, presence of extraintestinal manifestations, usage of 5-aminosalicylic acid and glucocorticoid, and with surgical treatment were independent risk factors of quality of life(unstandardized regression coefficient(95% confidence interval) -11.00(-12.24 to -9.76), -2.90(-5.26 to -0.55), -3.93(-6.25 to -1.61), -5.79(-9.87 to -1.71), -4.78(-7.79 to -1.76), -7.71(-11.07 to -4.35), -4.37(-8.00 to -0.73); P<0.001, =0.016, =0.001, =0.005 , =0.002, <0.001, =0.019), while the usage of biological agents was an independent protective factor of quality of life (unstandardized regression coefficient(95% confidence interval) 4.72(1.97 to 7.48), P=0.001). Conclusion:IBD patients generally have different degrees of anxiety, depression and sleep problems, which affect the quality of life of patients. Gender, disease activity and disease course are the influencing factors of mental disorders in IBD patients.
RESUMO
Objective:To analyze the clinical characteristics of patients with inflammatory bowel disease (IBD) complicated with intra- and extra-intestinal tumors, and so as to provide reference for clinical practice.Methods:From October 2008 to March 2022, the clinical data of 2 360 IBD patients diagnosed at the First Affiliated Hospital of Air Force Military Medical University were collected, and the IBD patients complicated with intra- and extra-intestinal tumors were screened out. IBD with colorectal cancer, small intestine cancer and intestinal lymphoma were enrolled into intra-intestinal tumor group, IBD complicated with other tumors except intra-intestinal tumors were enrolled into extra-intestinal tumor group. The clinical characteristics of the 2 groups were retrospectively compared, and the risk factors affecting survival of IBD complicated intra- and extra-intestinal tumor were analyzed. Kaplan-Meier method was used to draw the survival curve, Cox regression model was performed to analyze the prognostic risk factors, and independent sample t test, Fisher′s exact test and log-rank test were used for statistical analysis. Results:A total of 43 IBD patients with intra- and extra-intestinal tumor were screened out, and the overall tumor incidence rate was 1.82% (43/2 360). The rate of IBD complicated with intra-intestinal tumor accounted for 1.27% (30/2 360). Among them, the rate of ulcerative colitis (UC) complicated with intra-intestinal tumor was 1.48% (25/1 685), and the rate of Crohn′s disease (CD) complicated with intra-intestinal tumor was 0.74% (5/675). The rate of IBD with extra-intestinal tumor accounted for 0.55% (13/2 360). Among them, the rate of UC complicated with extra-intestinal tumor was 0.71% (12/1 685), and the rate of CD complicated with extra-intestinal tumor was 0.15% (1/675). There were no significant differences in the rate of intra- and extra-intestinal tumors between UC and CD patients (both P>0.05). In the intra-intestinal tumor group, the age when diagnosed with IBD and the age when tumor diagnosed were (37.0±13.8) years old and (47.7±13.5) years old, which were both lower than those of the extra-intestinal tumor group ((51.8±6.2) years old and (60.7±7.8) years old), and the differences were statistically significant ( t=-3.69 and -3.24, P=0.001 and 0.002). The lesion location when tumor diagnosed of UC patients with intra-intestinal tumor mainly was extensive colonic type(64.0%, 16/25), followed by left part colonic type and rectal type in turn (28.0%, 7/25 and 8.0%, 2/25). In UC patients with extra-intestinal tumor, mainly was rectal type (8/12), followed by left part colonic type (3/12) and extensive colonic type (1/12) in turn. There was statistically significant difference bwtween the UC patients with intra- and extra-intestinal tumor in the extent of lesions when tumor diaghosed (Fisher′s exact test, P<0.001). The activity of IBD of intra-intestinal tumor group when tumor diagnosed mainly was severe activity phase (46.7%, 14/30), followed by moderate activity phase, mild activity phase and remission phase in turn (33.3%, 10/30; 20.0%, 6/30 and 0). The activity of IBD of extra-intestinal tumor group when tumor diagnosed mainly was remission phase (7/13), followed by moderate activity phase, mild activity phase and severe activity phase in turn (3/13, 2/13 and 1/13). There were statistically significant differences between the 2 groups in the composition of IBD activity when tumor diagnosed (Fisher′s exact test, P<0.001). The survival analysis indicated the median survival time of IBD complicated with intra-intestinal tumor group was 145.9 months, and that of the extra-intestinal tumor group was 29.9 months. The results of multivariate Cox analysis showed that the occurrence of extra-intestinal tumor was an independent risk factor of patient survival rate( HR=5.119, 95% confidence interval 1.485 to 17.643, P=0.010). Conclusions:IBD patients had a high risk of developing intra- and extra-intestinal tumors. The intra-intestinal tumor group mainly is extensive colonic type and severe active period, while the extra-intestinal tumor group mainly is rectal type and remission period. Compared with that of the extra-intestinal tumor group, the age at time of IBD onset and tumor diagnosed of intestinal tumor are younger, and the survival time is longer.

RESUMO
Biological agents have been increasingly used in the treatment of inflammatory bowel disease (IBD) in China. As the types of biologics and approved indications gradually increase, the rationale, effective and safe use of various biological agents pose new challenges to clinicians. In order to standardize the use of biological agents to treat IBD, Inflammatory Bowel Disease Quality Control Center and Inflammatory Bowel Disease Group of Chinese Society of Gastroenterology organized experts to formulate this guidance on indications, contraindications, effectiveness, screening and preventing opportunistic infections, methods of application, response monitoring, issues for special population and safety for use of biological agents. This consensus is expected to facilitate the standard use of biologics in patients with IBD in China.
RESUMO
Background/Aims@#The incidence and prevalence of inflammatory bowel disease (IBD) is rising in Asia recently. The study aimed to obtain a comprehensive understanding of the current status of drug therapy and monitoring for IBD in Asia. @*Methods@#A questionnaire investigation on drug therapy and monitoring for IBD was conducted right before the 6th Annual Meeting of Asian Organization for Crohn’s & Colitis. Questionnaires were provided to Asian physicians to fill out via emails between March and May 2018. @*Results@#In total, responses of 166 physicians from 129 medical centers were included for analysis. Among the surveyed regions, the most average number of IBD specialist gastroenterologists and nurses was 4.8 per center in Taiwan and 2.5 per center in Mainland China, respectively. 5-Aminosalicylic acid/sulfasalazine (99.4%) was the most preferred first-line choice for mild-moderate ulcerative colitis (UC), meanwhile corticosteroid (83.7%) was widely applied for severe UC. The first-line medication for Crohn’s disease (CD) markedly varied as corticosteroid (68.1%) was the most favored in Mainland China, Japan, and South Korea, followed by infliximab (52.4%) and azathioprine (47.0%). Step-up strategy was preferred in mild-moderate UC (96.4%), while 51.8% of the physicians selected top-down treatment for CD. Only 25.9% and 17.5% of the physicians could test blood concentration of infliximab and antibody to infliximab in their hospitals, respectively. @*Conclusions@#The current status of drug therapy and monitoring for IBD in Asia possesses commonalities as well as differences. Asian recommendations, IBD specialist teams and practice of therapeutic drug monitoring are required to improve IBD management in Asia.
RESUMO
Objective:To analyze the trend of medication use in patients with ulcerative colitis (UC) in recent ten years in at Xijing Hospital, Air Force Military Medical University.Methods:From 2010 to 2019, the clinical data of 1 425 patients diagnosed with UC in the Department of Gastroenterology at Xijing Hospital, Air Force Medical University, were retrospectively collected. According to the period of medication, the UC patients were divided into year 2010 to 2014 group and year 2015 to 2019 group. The general information and the medication trend of year 2010 to 2014 group and year 2015 to 2019 group were analyzed. And then according to gender and age (<40 years old and ≥40 years old), patients were divided into subgroups and analyzed. Independent sample t test and chi-square test were used for statistical analysis. Results:The number of UC patients of year 2010 to 2014 group and year 2015 to 2019 group was 369 and 1 056, respectively. The percentages of patients in remission of the two groups were 9.5% (35/369) and 12.0% (127/1 056), respectively; the percentages of mild patients were 40.4% (149/369) and 41.6% (439/1 056), respectively; the percentages of moderate patients were 37.4% (138/369) and 28.9% (305/1 056), respectively; the percentages of severe patients were 12.7% (47/369) and 17.5% (185/1 056), respectively. There was no significant difference in the proportion of UC patients with different degrees between year 2010 to 2014 group and year 2015 to 2019 group ( P>0.05). There were no significant differences in the age and proportion of female between the year 2010 to 2014 group and year 2015 to 2019 group ((46.2±15.3) years old vs. (44.6±30.6) years old; 45.8%, 169/369 vs. 44.8%, 473/1 056; both P>0.05). The utilization rates of 5-aminosalicylic acid (5-ASA), glucocorticoid, immunosuppressants, and biological agents of the year 2015 to 2019 group were all higher than those of the year 2010 to 2014 group (96.8%, 1 022/1 056 vs. 90.0%, 332/369; 29.9%, 316/1 056 vs. 14.6%, 54/369; 8.4%, 89/1 056 vs. 2.4%, 9/369; 4.8%, 51/1 056 vs. 0.5%, 2/369, respectively), and the differences were all statistically significant ( χ2=26.766, 33.256, 15.315 and 14.038, all P<0.01). Within each of the year 2010 to 2014 group and the year 2015 to 2019 group, there were no significant differences between the female and male in the age, utilization rates of 5-ASA, glucocorticoid, immunosuppressants and biological agents ((47.2±13.6) years old vs. (45.3±16.5) years old, (43.1±12.9) years old vs. (45.8±39.5) years old, 88.8%, 150/169 vs. 91.0%, 182/200; 96.8%, 458/473 vs. 96.7%, 564/583; 13.6%, 23/169 vs. 15.5%, 31/200; 28.3%, 134/473 vs. 31.2%, 182/583; 2.4%, 4/169 vs. 2.5%, 5/200; 7.0%, 33/473 vs. 9.6%, 56/583; 0 vs. 1.0%, 2/200; 5.3%, 25/473 vs. 4.5%, 26/583; all P>0.05). In the patients aged≥40 years old of the year 2010 to 2014 group, the proportion of females was higher than that of the patients aged <40 years old (50.2%, 121/241 vs. 37.5%, 48/128), and the utilization rate of 5-ASA in patients aged ≥40 years old was lower than that of patients aged <40 years old (85.9%, 207/241 vs. 97.7%, 125/128), and the differences were statistically significant ( χ2=5.438 and 12.824, P=0.020 and P<0.01). In the year 2010 to 2014 group, there were no statistically significant differences in the utilization rates of glucocorticoid, immunosuppressants and biological agents between patients aged ≥40 years old and patients aged <40 years old (13.7%, 33/241 vs. 16.4%, 21/128; 2.1%, 5/241 vs. 3.1%, 4/128; 0 vs. 1.6%, 2/128; all P>0.05). In the year 2015 to 2019 group, the utilization rate of biological agents in patients aged≥40 years old was lower than that in patients aged<40 years old (3.7%, 23/630 vs. 46.5%, 198/426), and the difference was statistically significant ( χ2=4.721, P=0.030). In the year 2015 to 2019 group, there were no statistically significant differences in female proportion, utilization rates of 5-ASA, glucocorticoid, immunosuppressants and biological agents between patients aged≥40 years old and patients aged <40 years old (43.7%, 275/630 vs. 46.5%, 198/426; 96.0%, 605/630 vs. 97.9%, 417/426; 29.7%, 187/630 vs. 30.3%, 129/426; 8.6%, 54/630 vs. 8.2%, 35/426; all P>0.05). Conclusions:Compared with year 2010 to 2014, the number of UC patients remarkably increased in the year 2015 to 2019 in the Department of Gastroenterology, Xijing Hospiatal, Air Force Medical University. The utilization rates of 5-ASA, glucocorticoid, immunosuppressants and biological agents all increased in UC patients. The medication trends of UC patients with different gender were almost the same. The medication trends of UC patients with different age were different.
RESUMO
Objective:To analyze the clinical characteristics of patients with ulcerative colitis (UC)-associated neoplasia, including UC-associated dysplasia and ulcerative colitis-associated colorectal cancer (UC-CRC).Methods:From January 2010 to July 2019, the clinical data of 56 patients with UC-associated neoplasia at Xijing Hospital of Digestive Diseases were retrospectively analyzed. The patients with UC-associated neoplasia were divided into low-grade dysplasia (LGD) group (38 cases) and advanced neoplasia group (18 cases), the advanced neoplasia group included five patients with high-grade dysplasia and 13 patients with UC-CRC. Mann-Whitney U test, chi-square test and Fisher′s exact test were used for statistical analysis. Results:The age of patients with UC-associated neoplasia was (47.4±14.7) years old. The main type of lesion was extensive colitis (71.4%, 40/56). There were five patients (8.9%) complicated with colorectal stricture. The disease course of the advanced neoplasia group was longer than that of LGD group (10.5 years, 3.5 years to 14.5 years vs. 2.0 years, 1.0 year to 5.0 years), and the difference was statistically significant ( U=155.000, P=0.001). Four of the 18 patients of the advanced neoplasia group had colorectal stricture, the ratio was higher than that of LGD group (2.6%, 1/38), and the difference was statistically significant (Fisher exact test, P=0.033). In advanced neoplasia group, there were seven patients with multifocal lesions. Among 13 patients with UC-CRC, the lesions of five patients located in rectum, and the pathological type was mainly moderately differentiated adenocarcinoma (nine cases). Conclusions:The disease course of patients with advanced neoplasia is longer than that of patients with LGD, and the proportion of patients complicated with colorectal stricture is higher than that of patients with LGD. The proportion of multifocal lesions in patients with advanced neoplasia is higher, and the surveillance of neoplasia in UC patients should be strengthened.

Objective:To explore the therapeutic effects of lamb′s tripe extract and vitamin B12 (hereinafter referred to as lamb′s tripe) capsule on precancerous lesions of gastric mucosa in rats.Methods:Thirty-two rats of the 42 Wistar rats (model group) were selected for modelling, and in model group six rats died due to gavage, 10 rats were sacrificed for observing the results of modeling, and the left 16 rats were divided into administration group (eight rats) and non-administration group (eight rats). After modeling, five of the 10 rats without modelling treatment were selected as the normal control of the model group, the other five (negative control group) rats were included in drug intervention experiment. The drug intervention program was as follows: in administration group, rats were gavaged with lamb′s tripe 0.2 g/kg once per day for three months; in non-administration group and negative control group, rats were gavaged with 0.9% sodium chloride solution 0.2 g/kg once per day for three months. One rat died in each for the administration group and non-administration group due to gavage. Body weight gain, pH value of gastric juice and pathological changes of gastric mucosa of the three groups were evaluated. The number of nodules on gastric mucosal surface and the incidence and scores of precancerous lesions (intraepithelial neoplasia) in gastric mucosal were analyzed. The therapeutic effects of lamb′s tripe capsule on gastric mucosal precancerous lesions in rats were evaluated. Independent sample t test , Mann Whitney U test and chi-square test were used for statistical analysis. Results:The body weight gain of rats at the 6th week in the administration group was higher than that of rats in the non-administration group ((508.26±33.96) g vs. (495.50±23.01) g), and the pH value of gastric juice of rats in the administration group was lower than that of rats in the non-administration group (3.07±0.55 vs. 4.45±0.72), and the differences were statistically significant (both P<0.05). The number of proliferative nodules on the gastric mucosal surface of the rats in the administration group was less than that of rats in the non-administration group (the ratio of gastric fundus: 6.00(3.00, 7.00) vs. 11.00(7.00, 13.00); the ratio of gastric antrum: 0.00(0.00, 1.00) vs. 3.00(2.00, 4.00); the ratio of whole stomach: 7.00(3.00, 10.00) vs. 15.00(13.00, 17.00)), and the differences were statistically significant ( U=43.50, 49.00, 49.00, all P<0.05). The score of gastric mucosal precancerous lesions in the administration group was lower than that in the non-administration group(1.00±0.00 vs.1.14±0.38), and the incidence of precancerous lesions in the administration group was lower than that in the non-administration group (1/7 vs. 5/7), and the differences were statistically significant ( t=2.45, χ2=4.67, both P=0.031). Conclusions:Lamb′s tripe capsule can significantly inhibit the progression of precancerous lesions of gastric mucosa in rats, so as to play a role in preventing the occurrence of gastric cancer.
RESUMO
Objective:To explore the optimization strategy of the Asia-Pacific colorectal screening (APCS) scoring system in the screening of colorectal neoplasms.Methods:From February to Decomber in 2016 and March to December in 2018, at Xijing Hospital of Air Force Military Medical University and the First Affiliated Hospital of Xi′an Medical University, patients who received opportunistic screening colonoscopy were enrolled. Before colonoscopy, the APCS score (low-risk zero to one points, medium-risk two to three points and high-risk four to seven points), body mass index (BMI), fecal occult blood test (FOBT) and plasma methylated Septin9 gene ( mSEPT9) of all patients were detected and recorded. The results of colonoscopy and biopsy pathology were taken as the gold standard, the efficacies of the above methods in screening colorectal neoplasms were compared to determine and optimize the screening efficiency of APCS scoring system. Chi-square test was used for statistical analysis. Results:A total of 494 patients were screened, of whom 133 cases were diagnosed with colorectal polyps, including 86 cases of colorectal adenomatous polyps (82 cases of non-progressive adenoma, and four cases of advanced-adenoma), and 47 cases of non-adenomatous polyps. According to the APCS score, the detection rate of colorectal adenomatous polyps of the high-risk group (33.3%, 33/99) was 2.02 and 3.76 times higher than those of the medium-risk group (16.5%, 39/237) and low-risk group (8.9%, 14/158), respectively (both Bonferroni correction test, both P<0.016). The detection rate of colorectal adenomatous polyps of patients with BMI>23.9 kg/m 2 was significantly higher than that of patients with BMI≤23.9 kg/m 2 (22.2%, 59/266 vs. 11.8%, 27/228), and the difference was statistically significant ( χ2=9.126, P=0.003). There was no statistically significant difference in the detection rate of colorectal adenomatous polyps between patients with positive- mSEPT9 expression and patients with negative- mSEPT9 expression (22.4%, 15/67 vs. 17.3%, 47/271) ( χ2=0.913, P=0.378). Among 158 low and medium risk patients (APCS score≤three points) who underwent simultaneous BMI measurement, FOBT and plasma mSEPT9 test, the detection rate of colorectal adenomatous polyps in patients with BMI>23.9 kg/m 2 was higher than that in patients with BMI≤23.9 kg/m 2 (17.8%, 16/90 vs. 5.9%, 4/68), and the difference was statistically significant ( χ2=4.957, P=0.030). The redetection efficacy of colorectal adenomatous polyps in patients with BMI>23.9 kg/m 2 and FOBT-positive was higher than that in patients with BMI≤23.9 kg/m 2 and FOBT-negative (28.1%, 9/32 vs. 8.0%, 4/50) and the difference was statistically significant ( χ2=5.942, P=0.027). In addition, the redetection rate of colorectal adenomatous polyps of patients with positive expression of FOBT and plasma mSEPT9 was also higher than that of patients with negative expression (5/14 vs. 12.9%, 12/93), and the difference was statistically significant ( χ2=4.738, P=0.045). Conclusions:When the APCS scoring system is used for sequential screening of colorectal tumors, the optinal choice of BMI replacement or combined with FOBT can improve the patients′ compliance and screening efficiency, which has significant clinical significance and promotion value in the early diagnosis and treatment of colorectal neoplasms.
RESUMO
Objective:To investigate the risk factors of dysplasia in patients with ulcerative colitis (UC) in China.Methods:From March 1st, 2012 to December 30th, 2013, a total of 154 UC patients were prospectively enrolled from the following 11 hospitals, Xijing Hospital of Digestive Diseases, Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Peking Union Medical College Hospital, Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Nanfang Hospital affiliated to Southern Medical University, China-Japan Friendship Hospital, The Second Hospital of Hebei Medical University, West China Hospital affiliated to Sichuan University, The Seventh Medical Center of PLA General Hospital, Zhongshan Hospital affiliated to Xiamen University, and the First Affiliated Hospital of Anhui Medical University. The patients were followed up till December 1st, 2017. All the UC patients underwent colon endoscopy and histopathological evaluation. T test and Chi-square test were used for statistical analysis. Cox proportional risk model was used for identifying the risk factors of dysplasia in UC patients. Results:Finally, 133 UC patients were enrolled, the age was (50.0±11.9) years, the diagnosis age was (35.5±11.6) years, the course of disease was (14.5±6.7) years, and the number of endoscopic examinations was (3.4±1.6) times. A total of 21 patients were detected with dysplasia. No patients were detected with colorectal cancer. The results of univariate analysis revealed that the diagnosis age (hazard ratio ( HR)=1.05, 95% confidence interval ( CI) 1.01 to 1.10, P=0.009) and extensive colitis ( HR=2.92, 95% CI 0.97 to 8.79, P=0.057) were factors with statistically significant difference. The results of multivariate analysis revealed that the old age at diagnosis ( HR=1.06, 95% CI 1.02 to 1.11, P=0.003) and extensive colitis ( HR=3.68, 95% CI 1.21 to 11.19, P=0.022) were independent risk factors of dysplasia in UC patients. The cumulative incidence of dysplasia of UC patients with extensive colitis was higher than that of patients with left-sided colitis (24.3%, 17/70 vs. 6.3%, 4/63), and the difference was statistically significant ( χ2=8.023, P=0.005). Conclusions:Extensive colitis and older age at diagnosis are two independent risk factors of dysplasia in UC patients of our country. The cancer monitoring should be strengthened in UC patients with long course of disease and extensive colitis.
RESUMO
Objective:To investigate the effects of adherent-invasive Escherichia coli ( E. coli) LF82 on the structure and function of intestinal barrier in mice with ulcerative colitis (UC). Methods:Twenty-four specific pathogen free (SPF) C57BL/6 mice were divided into UC with E. coli LF82 group, UC group and healthy control group with eight mice in each group. The UC mice model was induced by dextran sulfate sodium (DSS). One week before modeling, the mice of UC with E. coli LF82 group were intragastric administrated with 1×10 9 colony-forming unit (CFU) E. coli LF82 to colonize the bacteria strain. The effects of E. coli LF82 on colitis of mice with UC were evaluated by disease activity index (DAI), gross morphological injury score, colonic mucosal injury index (CMDI), myeoloperoxidase (MPO) activity and pathological features. The ultrastructure and the changes of cytoskeleton F-actin of mice colonic tissues were detected by transmission electron microscope (TEM) and direct immunofluorescence. The ability of colonic mucin production and degree of fibrosis were estimated by periodic acid Schiff reaction (PAS) stain and sirius red stain. T test, least significant difference, repeated measurement analysis of variance and one-way analysis of variance were used for statistical analysis. Results:On the fourth, fifth, sixth and seventh day after the modeling, the DAI scores of UC with E. coli LF82 group were all higher than those of UC group ((2.53±0.38) points vs. (2.01±0.53) points, (3.02±0.62) points vs. (2.67±0.24) points, (3.13±0.61) points vs. (2.20±0.24) points, (3.27±0.28) points vs. (2.20±0.69) points, respectively), and the differences were statistically significant ( t=3.37, 2.25, 9.56 and 10.24, all P<0.05). The gross morphological injury score of mice colon of UC with E. coli LF82 group was higher than that of UC group ((6.17±1.94) points vs. (2.83±0.98) points), and the difference was statistically significant ( t=-3.75, P<0.05). The CMDI and MPO activity of UC with E. coli LF82 group were both higher than those of UC group ((16.80±2.79) points vs. (11.80±3.11) points, (729.3±77.5) U/mg vs. (594.4±31.9) U/mg), and the differences were statistically significant ( t=-2.83; mean difference=134.82, 95% confidence interval ( CI) 72.12 to 197.51; both P<0.05). The results of TEM showed that the E. coli LF82 could invade the submucosa of colon and caused further injury of colonic tissues in mice. The distribution of cytoskeleton F-actin of mice colonic tissues changed. The results of PAS staining showed that the percentages of PAS positive cells of UC with E. coli LF82 group and UC group were both lower than that of healthy control group ((32.40±8.02)% and (41.90±8.99)% vs. (57.70±11.52)%), and the difference was statistically significant ( F=17.63, P<0.01). The percentage of PAS positive cells of UC with E. coli LF82 group was lower than that of UC group, and the difference was statistically significant (mean difference=-9.50, 95% CI -18.33 to -0.67, P<0.05). The results of sirius red staining showed that the villous epithelium of colon mucosa of UC with E. coli LF82 group was partially injured and collagen fibers hyperplasia was serious. The area ratios of collagen fiber of UC with E. coli LF82 group and UC group were both higher than that of healthy control group ((51.83±5.78)% and (37.11±5.59)% vs. (15.41±2.25) %), and the difference was statistically significant ( F=86.72, P<0.01). The area ratio of collagen fiber of UC with E. coli LF82 group was higher than that of UC group, the difference was statistically significant (mean difference=14.83, 95% CI 8.91 to 20.76, P<0.05). Conclusions:E. coli LF82 can aggravate DSS-induced colitis in UC mice, leading to changes in colon ultrastructure and cytoskeleton, it can also reduce the ability of mucus secretion of colon of mice and increase the degree of colonic tissues fibrosis.
RESUMO
Background: The incidence of inflammatory bowel disease (IBD) is increasing in China in recent years, and the impact of psychological factors on IBD has been widely concerned. Aims: To investigate the psychological status of IBD patients and the influencing factors for anxiety and depression disorders. Methods: A total of 358 inpatients with IBD admitted from Oct. 2018 to Dec. 2019 at the Xijing Hospital were recruited; 170 patients with colonic polyps were served as controls. The presence of anxiety and depression were determined using the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS), respectively. Demographics, disease characteristics, and medication information were also collected. Influencing factors for anxiety and depression disorders were analyzed by logistic regression model. Results: (1) The prevalence of anxiety and depression disorders, as well as the score of SAS and SDS were higher in IBD patients than in controls (P<0.05). (2) CD was associated with a higher prevalence of comorbid depression as compared with UC (P<0.05). (3) SAS and SDS score in active CD were higher than those in remission stage (P<0.05). (4) SAS and SDS score in active IBD increased in parallel with the increase of disease activity (P<0.05). (5) College education or above (OR=8.888, 95% CI: 1.714-46.095, P=0.009 for anxiety; OR=3.831, 95% CI: 1.039-14.760, P=0.008 for depression), and the severe active disease (OR=12.293, 95% CI: 1.501-100.679, P=0.041 for anxiety; OR=3.230, 95% CI: 1.051-5.506, P=0.040 for depression) were risk factors for anxiety and depression, while serving as a office clerk was a protective factor for depression (OR=0.620, 95% CI: 0.113-0.928, P=0.043). (6) SAS and SDS score decreased after 3 months of medication in IBD patients (P<0.05); SDS score of infliximab treatment group was lower than that of 5-aminosalicylic acid and steroid treatment groups (P<0.05). Conclusions: The prevalence of anxiety and depression disorders in IBD patients is considerably high. The degree of anxiety and depression is closely related to the disease activity. After standard treatment, the degree of anxiety and depression decreased. IBD patients at risk for anxiety and depression disorders should be screened for psychological comorbidities and appropriate psychotherapy should be offered.
