ABSTRACT

Small intestinal bacterial overgrowth (SIBO) is characterized by changes in the number or species of small intestinal flora. Patients with liver cirrhosis often have intestinal congestion, edema, and delayed peristalsis and develop SIBO, which can further aggravate intestinal abnormalities. In patients with liver cirrhosis, SIBO can lead to significant adverse clinical outcomes, and since the increase in intestinal permeability may cause bacterial translocation into systemic circulation, SIBO is considered an important risk factor in the pathogenesis of liver cirrhosis, spontaneous bacterial peritonitis, and hepatic encephalopathy. Antibiotics, especially rifaximin, are the most effective therapies for SIBO, and in addition, studies are being conducted to investigate the efficacy of potential therapies such as prokinetic agents, probiotics, non-selective β-receptor blocker, and liver transplantation.

ABSTRACT

Objective:To summarize the clinical features of intestinal Beh?et′s disease, so as to provide reference for the diagnosis of the disease.Methods:From April 1 2014 to January 31 2019, the clinical data of 47 patients diagnosed as intestinal Beh?et′s disease at the Second Hospital of Hebei Medical University were retrospectively analyzed, which included initial symptoms, gastrointestinal symptoms, complications, erythrocyte sedimentation rate (ESR), the levels of C reactive protein (CRP), hemoglobin, serum albumin, results of acupuncture test, gastrointestinal involved site and ulcer shape. At the same time, gender differences of clinical manifestations were compared. Chi-square test was used for statistical analysis.Results:Among 47 patients with intestinal Beh?et′s disease, the initial symptoms of 26 (55.3%) cases were gastrointestinal symptoms. Abdominal pain was the most common symptom, the others were diarrhea, anorexia, abdominal distension and perianal abscess, and the incidence rate was 80.9%(38/47), 46.8% (22/47), 42.6% (20/47), 36.2% (17/47) and 2.1% (1/47), respectively. The main complications were gastrointestinal bleeding, perforation and obstruction, and the incidence rates was 40.4% (19/47), 4.3% (2/47) and 4.3% (2/47), respectively. Thirty-seven (78.7%) patients had different degrees of hypoalbuminemia (serum albumin<35 g/L). The CRP level of 36(76.6%) patients increased. The ESR of 36 (76.6%) patients increased. Twenty-two (46.8%) patients had mild anemia (hemoglobin<90 g/L). The acupuncture test was positive in 25 (53.2%) patients. The involved sites of gastrointestinal tract were terminal ileum and ileocecal junction, colon, esophagus, duodenum and jejunum, stomach, and rectum, the proportion was 57.4% (27/47), 27.2% (13/47), 23.4% (11/47), 23.4% (11/47), 17.0% (8/47) and 8.5% (4/47), respectively. All 47 (100.0%) patients had oral ulcers. 62.1%(18/29) patients presented with multiple ulcers under endoscope. The shape of ulcer was round ulcer, irregular ulcer, and longitudinal ulcer, the proportion was 48.3% (14/29), 34.5% (10/29) and 17.2 (5/29), respectively. The incidence rate of genital ulcer of female patients with intestinal Beh?et′s disease was higher than that of male patients with intestinal Beh?et′s disease (85.7%, 18/21 vs. 30.8%, 8/26), and the difference was statistically significant ( χ2=14.189, P<0.01). There were no significant differences between the female group and the male group in the incidence rate of oral ulcer, abdominal pain, diarrhea, and positive rate of acupuncture test (100.0%, 21/21 vs. 100.0%, 26/26; 85.7%, 18/21 vs. 76.9%, 20/26; 42.9%, 9/21 vs. 50.0%, 13/26; 52.4%, 11/21 vs. 58.3%, 14/26, all P>0.05). Conclusions:The common clinical symptoms of intestinal Beh?et′s disease are oral ulcers, abdominal pain, diarrhea and genital ulcer. Female patients with intestinal Beh?et′s disease are more likely to develop genital ulcer than male patients with intestinal Beh?et′s disease. Multiple ulcers are more common under endoscopy, which are round ulcer, irregular ulcer and longitudinal ulcer. The most common sites are the terminal ileum and ileocecal junction, followed by colon, esophagus and other parts.

ABSTRACT

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.

ABSTRACT

Objective:To explore the risk factors, clinical features, endoscopic characteristics and the efficacy of antiviral therapy in ulcerative colitis (UC) patients complicated with cytomegaloviremia (CMV) and Epstein-Barr (EB) viremia.Methods:From April 1, 2014 to January 31, 2019, at The Second Hospital of Hebei Medical University, a total of 320 UC patients hospitalized at the Department of Gastroenterology were enrolled. According to the pathogens, the patients were divided into four groups: complicated with CMV and EB viremia group ( n=35), only complicated with CMV viremia group ( n=33), only complicated with EB viremia group ( n=52) and without CMV and EB viremia group ( n=200). Clinical features and the efficacy of antiviral therapy of the patients were retrospectively analyzed. Multivariate logistic regression was used to analyze the risk factors of UC complicated with CMV and EB viremia. Kruskal-Wallis H test, Chi-square test and Fisher exact test were used for statistical analysis. Results:The proportion of patients of age>60 years old (42.86%, 15/35), the rate of glucocorticoid use (51.43%, 18/35) within three months before onset and the inefficacy rate of glucocorticoid treatment (22.86%, 8/35) of UC complicated with CMV and EB viremia group were all higher than those of UC without CMV and EB viremia group (14.00%, 28/200; 24.50%, 49/200; 1.00%, 2/200), and the differences were statistically significant ( χ2=17.062, 10.598 and 29.769; all P<0.01). However, there were no statistically significant differences between UC complicated with CMV and EB viremia group and UC without CMV and EB viremia group in gender, and treatment of 5-aminosalicylic acid (5-ASA), azathioprine and infliximab within three months before onset (all P>0.05). The proportion of patients with fever (54.29%, 19/35), abdominal pain (91.43%, 32/35), hematochezia (94.29%, 33/35), weight loss (28.57%, 10/35), severe disease activity (94.29%, 33/35), total colon involvement (91.43%, 32/35), serum albumin less than 30 g/L (71.43%, 25/35) and hemoglobin less than 100 g/L (48.57%, 17/35) of UC complicated with CMV and EB viremia group were all higher than those of UC without CMV and EB viremia group (13.50%, 27/200; 43.00%, 86/200; 44.00%, 88/200; 13.50%, 27/200; 38.00%, 76/200; 65.00%, 130/200; 18.00%, 36/200 and 18.50%, 37/200), and the differences were statistically significant ( χ2=31.475, 27.945, 32.930, 5.100 and 40.194, Fisher exact test, χ2=44.242 and 15.220, all P<0.01). However, there were no statistically significantl differences in clinical classification and disease course (all P>0.05). The incidence rates of deep ulcer (45.71%, 16/35), irregular ulcer (42.86%, 15/35) and longitudinal ulcer (8.53%, 3/35) under endoscopy of UC complicated with CMV and EB viremia group were significantly higher than those of UC without CMV and EB viremia group (1.50%, 3/200; 3.50%, 7/200 and 1.00%, 2/200), and the differences were statistically significant ( χ2=72.521 and 49.837, Fisher exact test, all P<0.01). The incidence rates of deep ulcer and irregular ulcer under endoscopy of UC complicated with CMV and EB viremia group were higher than those of UC only complicated with EB viremia group (15.38%, 8/52 and 11.54%, 6/52), and the differences were statistically significant ( χ2=9.663 and 11.206, P=0.002 and 0.001). The results of Multivariate Logistic regression analysis showed that severe disease activity, serum albumin level less than 30 g/L, and deep ulcer and irregular ulcer under endoscopy were risk factors of UC patients complicated with CMV and EB viremia (odds ratio=48.519, 44.352, 53.432 and 39.989, 95% confidence interval 9.057 to 587.669, 4.499 to 437.245, 3.302 to 864.670 and 3.418 to 467.910, all P<0.05). The improvement rate of antiviral therapy in UC complicated with CMV and EB viremia group (73.53%, 25/34) was significantly lower than those of UC only complicated with CMV group (96.88%, 31/32) and UC only complicated EB viremia group (95.65%, 44/46), and the differences were statistically significant ( χ2=6.989 and 6.310, P=0.008 and 0.012). Conclusions:UC patients with severe disease activity, serum albumin level less than 30 g/L, and deep ulcer and irregular ulcer under endoscopy are more likely to develop CMV and EB viremia. The more severe the disease, the worse the treatment response, so it is necessary to strengthen the screening to CMV and EB virus infection in UC patients.

ABSTRACT

Inflammatory bowel disease includesulcerative colitis and Crohn′s disease.At present, it is generally believed that the pathogenesis of inflammatory bowel disease is that environmental factors act on the genetic susceptible.With the participation of intestinal flora, it starts the intestinal immune response which is difficult to stop and alternates between attack and remission.However, the pathogenesis of IBD is not very clear, so it is important to further explore and clarify the pathogenesis of IBD for the search of new treatment.Tumor necrosis factor-like ligand 1 aberrance(TL1A) is a newly discovered new member of tumor necrosis factor family and a susceptible gene of inflammatory bowel disease.TL1A plays a key role in the regulation and connection between innate immunity and adaptive immunity of mucosal inflammation, and thus plays an important role in inflammatory bowel disease.This article reviews the role of TL1A in the immune regulatory mechanism of inflammatory bowel disease.

ABSTRACT

Objective To explore the effectiveness of endoscopic ultrasound( EUS)-guided holmium laser ablation for primary pancreatic implantation tumor in nude mice. Methods Pancreatic cancer cell line SW1990 were implanted into 204-6-week-old male balb/c nude mice to establish primary pancreatic implantation tumor in situ models. Then the nude mice were randomly divided into two groups, the treatment group(n=10) and the control group(n=10). The treatment group underwent EUS-guided holmium laser ablation in the pancreatic tumor. And no interventions were given to the control group. The volume of tumors of the two groups were measured under EUS at time points of 7 d, 14 d and 28 d after ablation. The activities, appetites and psychosis of all nude mice were evaluated in the meantime. At 28 d after ablation, lesions of pancreas were dissected and sliced for H&E staining. Results There were no complications in the treatment group, and all nude mice could tolerate the procedure. The mental state, activities and appetites of nude mice in the experimental group were better than those in the control group. Tumors of the control group enlarged. There was significant difference in the tumor size between the two groups at 28 d after ablation. HE staining showed coagulation necrosis in the ablation area. Conclusion EUS-guided holmium laser, producing coagulative necrosis in the ablation area, is effective for primary pancreatic implantation carcinoma in nude mice for about 28 days.

ABSTRACT

Objective@#To explore the risk factors of cytomegalovirus (CMV) infection or reactivation in ulcerative colitis (UC) patients.@*Methods@#We performed a search at the databases of Pubmed, Cochrane, Embase, CNKI, Wanfang, SinoMede and VIP up to March 2017. A search strategy was constructed by using a combination of the following words: "inflammatory bowel disease or IBD" or "ulcerative colitis or UC" and "cytomegalovirus or CMV" . Literature was screened according to the inclusion and exclusion criteria and statistics was analyzed using RevMan 5.3 software provided by Cochrane collaboration network and analyzed using Stata 12.0 software to evaluate publication bias.@*Results@#After searching and screening, we included 18 case-control studies finally. Meta-analysis showed that the risk of CMV infection or reactivation in severe UC was 1.45 times that in mild to moderate UC and the risk in whole colon was 1.54 times that of patients with left colon and rectum with the pooled OR values as 1.45 (1.02-2.05) and 1.54 (1.05-2.27). The risk of CMV infection in middle-aged patients with UC was higher than that in young patients with the pooled MD values of 4.60(2.13-7.07). The therapies with glucocorticoid and immunosuppressive agents such as azathioprine, cyclosporine and methotrexate were high risk factors of CMV infection or reactivation in UC patients, with the pooled OR values as 3.87 (2.70-5.53) and 2.07 (1.29-3.32), but the duration of UC, treatment with 5-Amino salicylic acid/salazosulfapyridine (5-ASA/SASP) and infliximab had no statistically significant correlation with the CMV infection or reactivation in UC patients, with the pooled OR values as -1.20 (-2.64-0.24), 0.94 (0.61-1.42) and 1.50 (0.65-3.44).@*Conclusions@#In patients with severe UC, whole colon lesions and the therapy with glucocorticoid and immunosuppressive agents were the risk factors of CMV infection or reactivation. The risk of CMV infection or reactivation in middle-aged patients was higher than that in young patients.

The patients were divided into EB-viremia group (trial group, n=43) and non-EB-viremia group (control group, n=196) according to EB virus-DNA detection. The general condition, clinical characteristics and therapeutic efficacy of the two groups were compared. The risk factors and the effect of antiviral therapy on the remission of symptoms of UC complicated with EB-viremia were analyzed. Chi-square test and logistic analysis were used for statistical analysis.@*Results@#There were no significant differences in gender, age, clinical type, lesion range, the proportion of patients treated with 5-aminosalicylic acid or corticosteroids, the percentage of patients with diarrhea and bloody stool, the proportion of patients with spontaneous bleeding, platy ulcer and longitudinal ulcer under colonoscopy, the course of disease or Mayo score between the trial group and control group (all P>0.05). The proportions of patients with smoking history and severe disease, treatment with azathioprine and 6-mertocapurine (6-MP), treatrnent with infliximab, symptoms of fever or abdominal pain and deep and large ulcer under colonoscopy in the trial group were all higher than those in the control group, and the differences were all statistically significant (χ2=5.304, 6.608, 6.718, 6.939, 8.783, 4.493 and 5.425, all P<0.05). The results of multivariate logistic regression analysis showed that smoking history and treatment with azathioprine and 6-MP were risk factors of UC complicated with EB-viremia (OR=2.801 and 9.343, 95%CI 1.170 to 6.703 and 1.749 to 49.922, P=0.021 and 0.009). The improvement rates of the trial group and control group were 79.1%(34/43) and 95.4%(187/196), respectively. There was a significant difference in the improvement rate between the two groups (χ2=10.551, P=0.001). In the trial group, 12 patients (27.9%) received ganciclovir treatment, fonr patients (9.3%) had foscarnet sodium treatment, 21 patients (48.8%) were treated with the combination of these two medications and six cases (14.0%) did not received any antiviral treatment. After three weeks, the improvement cases of the above regimens were 8, 4, 16 and 6, respectively. There were no statistically significant differences in the improvement rate of patients with and without antiviral treatment, further more, no difference was found in the improvement rate of patients with different antiviral treatments (all P>0.05).@*Conclusions@#Smoking history and purine treatment are risk factors of UC complicated with EB-viremia.

ABSTRACT

Objective To investigate the significance of Thyroid hormone receptor interactor 6 (TRIP6) in the development of pancreatic cancer.Methods The protein expression of TRIP6 was assessed immunohistochemically in 43 normal pancreatic (NP) tissues,18 pancreatic intraepithelial neoplasia (PanIN)tissues and 50 pancreatic ductal adenocarcinoma (PDAC) tissues using the immunohistochemical scores (IHCS) to evaluate the positivity of TRIP6 expression.And the expression of TRIP6 in different tissues was analyzed,and the correlations of TRIP6 expression in PDAC tissue with clinicopathological characteristics were analyzed.Results TRIP expression was negative or extremely low in normal pancreas,which changed from weak positivity to strong positivity with the increased degree of tissue atypia.TRIP6 was strongly expressed in PDAC.The IHCS of TRIP6 expression in NP,PanIN-1,PanIN-2,PanlN-3 and PDAC was(0.010 ±0.003),(0.029 ± 0.003),(0.055 ± 0.014),(0.090 ± 0.025) and (0.094 ± 0.030),and the differences were statistically significant (P <0.01).The results of paired comparison of either two of them above showed that the expression of TRIP6 in NP group was significantly lower than that in other four groups,the expression in PanIN-1 group was significantly lower than that in other three groups except NP group,the expression of PanIN-2 group was significantly lower than that of PanIN-3 group and PDAC group,and all the differences were statistically significant (all P < 0.05).However,the expression of PanIN-3 group was lower than that of the PDAC group,but the difference was not statistically significant (P =0.13).The expression level of TRIP6 was associated with neural invasion (P<0.01),lymph node metastasis (P=0.013),distant metastasis (P=0.018),differentiation of PDAC (P=0.019) and CA19-9 level(P<0.01) in PDAC,but not with patients' gender,age,tumor size,location,vascular infiltration,infiltration depth and TNM stage.Conclusions Overexpression of TRIP6 is an early event in PDAC.TRIP6 may be involved in the whole process of PDAC development and progression.

ABSTRACT

Objective To evaluate the indications and clinic outcomes of vaginal high uterosacral ligament suspension (HUS) for treatment of recurrent advanced pelvic organ prolapse (POP). Methods This retrospective study analyzed 42 women with recurrent advanced POP who were referred to Fourth Medical Center of PLA General Hospital and underwent transvaginal HUS between November 2005 and January 2018. Primary surgeries included 30 vaginal colporrhaphy, 5 Manchester operation, 5 transvaginal mesh repair,2 sacrospinous ligament fixation.The median time for recurrence from primary pelvic floor repair surgery was 9 months, including 14 cases (33%, 14/42)≤3 months (median time was 2 months) and 25 cases (67%, 28/42) longer than 3 months (median time was 18 months).The rate of recurrent prolapse in stageⅢorⅣ was 79% (33 cases), 45% (19 cases) and 17%(7 cases) in anterior, apical and posterior compartment respectively. Results Transvaginal high bilateral uterosacral ligaments were identified and used for successful vaginal vault suspension after vaginal hysterectomy and residual cervical resection in all 42 consecutive patients. The cases of transvaginal mesh used in anterior wall and posterior wall were 25 (60%, 25/42) and 3 (7%, 3/42) respectively. There was no major intra-and postoperative complications,such as ureter and other pelvic organ injury. The median time of follow-up was 5.3 years after transvaginal HUS. The points of pelvic organ prolapse quantification system reduced significantly and point C improved from+0.3 cm to-8.2 cm after reoperation (P<0.01). The objective cure rate were 100% (42/42) both in apex and posterior compartment,while 93% (39/42) in anterior compartment. None had reoperation or pessary usage for recurrence of prolapse. Conclusion Transvaginal HUS with vaginal wall repair could be as a safety, cost-effective, minimal traumatic and durable procedure for recurrent POP in the most of cases.

ABSTRACT

Objective: To investigate the clinicopathological features and molecular phenotypes of gastric cancer with enteroblastic dif-ferentiation (GCED). Methods: A retrospective analysis of 337 patients with gastric adenocarcinoma diagnosed by the pathology de-partment of the First Affiliated Hospital of Zhejiang University in March 2013-2017 was conducted. Of them, 8 patients were diag-nosed with gastric carcinoma with intestinal blastocyte differentiation. All the patients were elderly, including 6 men and 2 women. The onset age was 68-83 years (mean 76.6 years). Two cases had serum AFP≥200 μg/L before treatment. According to the histopatho-logical morphology, the immunophenotype was analyzed by immunohistochemistry, the SALL4 gene was detected using reverse tran-scription-polymerase chain reaction (RT-PCR), and the relevant literature was reviewed. Results: Microscopically, all cases had primi-tive enteroid structures, consisting of cubic or columnar cells with clear cytoplasm, and immunohistochemical staining showed positivi-ty for either AFP and GPC3 or SALL4. The expression of SALL4 mRNA was significantly increased by RT-PCR. Follow-up from 1 to 5 years showed that 5 patients had liver and other organ metastases, 2 patients died, and 1 patient survived without a tumor. Conclusions:GCED is a rare invasive gastric adenocarcinoma with a worse prognosis than that of normal intestinal adenocarcinoma. The treatment of general intestinal adenocarcinoma has little effect. There are some characteristic changes in histology. It would be helpful for diag-nosis and differential diagnosis if clinicians are familiar with the tumor spectrum and genetic characteristics. Target therapy for an origi-nal marker, such as SALL4, has a bright future.

ABSTRACT

Background:Ulcerative colitis(UC)patients are the high risk population of cytomegalovirus(CMV)infection. CMV infection may aggravate the disease progression of UC,and the prognosis of UC patients with CMV infection may be improved by antiviral therapy. Aims:To systematically evaluate the effects of CMV infection and antiviral therapy on prognosis of UC patients. Methods:PubMed,Cochrane Library,Embase,CNKI,Wanfang,SinoMed and VIP database were retrieved to collect the case-control studies studying the effects of CMV infection and antiviral therapy on prognosis of UC patients. Meta-analysis was conducted by RevMan 5.3 software. Results:Twenty case-control studies were enrolled. Meta-analysis showed that UC patients in CMV infection group were more serious(OR=1.62,95% CI:1.13-2.33),and had larger intestinal lesions(OR=0.63,95% CI:0.43-0.92),higher risks of steroid dependence/resistance(OR=6.13, 95% CI:1.98-19.00)and colectomy(OR=1.64,95% CI:1.14-2.36). Antiviral therapy for UC patients with CMV infection significantly improved the early clinical remission rate(OR =2.08,95% CI:1.03-4.17),decreased risk of colectomy(OR=2.12,95% CI:1.06-4.22). Conclusions:CMV infection can aggravate the progress of UC,enlarge the extent of intestinal lesion,increase the risks of steriod dependence/resistance and colectomy. Antiviral therapy significantly improves the early clinical remission rate,and decreases the risk of colectomy.

ABSTRACT

Objective@#To explore the effects of macrophages with high expression of TL1A on the activation and proliferation of HSCs in vitro. @*Methods@#The Bone marrow-derived macrophages (BMMs) and peritoneal macrophages (PMs) from wild type (WT) and myeloid-overexpressed TL1A transgenic mice were isolated, differentiated and activated. HSCs were harvested from activated macrophages culture supernatant (CM). HSCs were detected by immunofluorescence and real-time Q-PCR. And the proliferation was detected by CCK-8 and BrdU assay kit. The levels of IL-1β and PDGF-BB in macrophage culture supernatants were determined by enzyme-linked immunosorbent assay (ELISA). @*Results@#BMMs-derived CM-intervention HSCs were used to detect the expression of α-smooth muscle actin (α-SMA) on the 2nd, 4th and 6th day respectively by immunofluorescence method. There was no significant difference between the two groups on the 2 nd and the 6th day, P > 0.05; On day 4, the CM/Tg group was significantly higher than that of CM/WT group, P < 0.01; the results of CMs derived from PMs were consistent with the above trend. The expression of α-SMA mRNA on the 2nd, 4th and 6th day was detected by real-time Q-PCR method using BM-derived CMs. No significant difference was found between the groups on the 2nd day (P > 0.05).α-SMA mRNA increased further on the 4th and 6th day, and the level of CM/Tg in CM/Tg group was significantly higher than that in CM/WT group (P < 0.05). The detection results of CMs derived from PMs were consistent with the above trend. The results of CCK-8 assay and BrdU assay showed that the proliferation rate of HSCs in CM Tg group was significantly higher than that in CM/WT group (P < 0.01). The CMs derived from PMs were used to interfere with HSCs. And the results were consistent with the above trend. For BMMs, the levels of IL-1β and PDGF-BB in the lipopolysaccharide (LPS) + IFNγ/Tg culture supernatant were significantly higher than those in the LPS+IFNγ/WT group (P < 0.01). For the culture supernatants of PMs Liquid test results consistent with the above trend. @*Conclusion@#Macrophages with high expression of TL1A could enhance the activation and proliferation of HSCs by increasing the secretion of IL-1β and PDGF-BB.

ABSTRACT

Objective To investigate the effects of tumor necrosis factor-related ligand-1A(TL1A)on activation of T helper 9(Th9)cells of colonic tissues in chronic experimental colitis mice.Methods The chronic experimental colitis mice model was established with drinking dextran sulfate sodium salt(DSS).A total of 32 lymphocytes TL1A highly expressed mice and wild type(WT)mice were divided into WT control group, transgene control group,WT modeling group and transgene modeling group.The mice of control groups were administrated with distilled water. The mice of modeling groups received 3% DSS in drinking water discontinuously.The mice were sacrificed on 29 days after modeling.Body mass was measured,length of colon was recorded,scores of gross colon and the disease activity index(DAI)were calculated.The colonic morphological changes were observed by hematoxylin-eosin(H-E)staining.The lamina propria mononuclear cells(LPMC)were isolated and the number of Th9 cells was tested by flow cytometry.The levels of interleukin-9(IL-9)in serum and LPMC were detected by enzyme-linked immunosorbent assay(ELISA).The expressions of IL-9 protein and mRNA of the colonic tissues were measured by Western blotting and real-time polymerase chain reaction(PCR),respectively.T test and single factor analysis of variance were performed for statistical analysis.Results The percentage of body mass loss of WT modeling group was lower than that of transgene modeling group(16.2% ± 1.0% vs 18.9% ± 1.2%),and the difference was statistically significant(t=4.90, P<0.05).The scores of gross colon,DAI and pathology of transgene modeling group were all higher than those of WT modeling group(2.80 ± 0.64 vs 1.60 ± 0.31,2.55 ± 0.20 vs 1.58 ± 0.17,and 11.85 ± 0.86 vs 9.50 ± 0.79),and the differences were statistically significant(t=4.77,10.45 and 5.69,all P<0.05).The number of LPMC in transgene modeling group was higher than that of WT modeling group(3.70×106± 0.28×106vs 2.65×106± 0.32 × 106)and the difference was statistically significant(t= 6.98,P< 0.05).The percentage of Th9 in total CD4+T cells of LPMC in colonic tissues of transgene modeling group was higher than that of WT modeling group(0.54% ± 0.04% vs 0.23% ± 0.03%),and the difference was statistically significant(t= 17.54,P< 0.05).The serum IL-9 level of transgene modeling group was higher than that of WT modeling group((170.23 ± 5.69)pg/mL vs(150.62 ± 6.45)pg/mL),and the difference was statistically significant(t= 6.50,P< 0.05).The level of IL-9 secreted by LMPC of transgene modeling group was higher than that of WT modeling group((265.21 ± 8.76)pg/mL vs (237.58 ± 10.24)pg/mL),and the difference was statistically significant(t= 5.80,P< 0.05).The expressions of IL-9 protein and mRNA of transgene modeling group were higher than those of WT modeling group(1.31 ± 0.09 vs 1.18 ± 0.03,and 8.26 ± 1.13 vs 2.25 ± 0.29,respectively),and the differences were statistically significant(t=3.88 and 14.57,both P< 0.05).Conclusion TL1A high expression in lymphocytes can promote Th9 cells differentiation and IL-9 secretion which involved in the genesis of chronic experimental colitis.
