RESUMO
AIM:This study aim to investigate the effects of lipopolysaccharide(LPS)-induced inflammation on the aging phenotype of hematopoietic stem/progenitor cells(HSPCs)in the bone marrow(BM)and spleen of mice.METHODS:(1)Young(2-month old)wild-type(WT)mice were treated with LPS to establish an actue inflammation model.The percentage of HSPCs in the BM and spleen of mice after LPS stimulation,as well as the ratio of mature cells in peripheral blood(PB)and spleen,were analyzed using flow cytometry.The proliferation of HSPCs in the BM and spleen was evaluated by examining the expression of the proliferation marker Ki67.In addition,changes in CD45 expression on HSPCs in the spleen of mice following LPS exposure were investigated by flow cytometry.(2)The percentage of HSPCs in BM and mature cells in PB and spleen of both young(2-month old)and old(24-month old)WT mice were analyzed by flow cytometry.(3)The transcriptome changes of hematopoietic stem cells(HSCs)after LPS stimulation was performed by an in silico analysis.RESULTS:(1)Mice exposed to LPS exhibited a significant increase in the percentage of HSPCs in BM and a marked elevation in the percentages of myeloid cells in PB and spleen compared to the mice in control group(P<0.05).(2)LPS exposure resulted in increased spleen weight and cell counts(P<0.05),along with a higher per-centage of HSPCs in the spleen compared to controls(P<0.05).(3)LPS stimulation promoted the proliferation of HSPCs in the BM and spleen(P<0.05).(4)The expression of CD45 was reduced on HSPCs from spleen of mice after LPS stimu-lation(P<0.01).(5)In comparison to young mice,aged mice showed an increase in spleen weight and a higher percent-age of HSPCs in the spleen(P<0.05).(6)Aged mice,in comparison to young mice,demonstrated a significantly higher percentage of HSPCs in the BM and myeloid skewing in the PB and spleen(P<0.01).(7)The silico analysis revealed up-regualtion of reactive oxygen species(ROS)and apoptosis signaling in HSPCs following LPS stimulation.CONCLU-SION:Young HSPCs stimulated by LPS exhibited an increase in cell number,a bias towards myeloid differentiation,en-hanced extramedullary hematopoiesis,and elevated levels of ROS and apoptosis,all of which collectively manifested the aging phenotype of HSPCs.
RESUMO
Background:Complete colonoscopy is key to the diagnosis and treatment of colorectal disease,its role in reducing the morbidity and mortality of colorectal cancer is well known.Nonetheless,there are numerous factors,not just from the endoscopist's perspective but also from the patient's,that can potentially increase the difficulty of completing a colonoscopy.Aims:To identify patient-related factors that influenced the difficulty of a colonoscopy.Methods:Through two rounds of expert consultation,the factors that might affect the difficulty of colonoscopy were selected.A total of 1621 consecutive painless colonoscopies from Jan.2021 to Jan.2022 at the endoscopy center of The Affiliated Wuxi People's Hospital of Nanjing Medical University were evaluated in a retrospective manner.Factors including demographic data,cecal insertion time,adenoma detection rate and so on were recorded.These factors were analyzed to determine their association with difficulty by using Logistic regression model.Results:A total of 29 patient-related factors affecting the difficulty of colonoscopy were selected.Through retrospective analysis,the mean age of 1621 cases was(47.45±13.27)years,of which 45.8%were male and the mean body mass index was(23.32±3.11)kg/m2.Logistic regression analysis revealed that age≥60 years(OR=2.890,95%CI:1.957-4.269,P<0.001),female gender(OR=0.324,95%CI:0.217-0.484,P<0.001),history of gynecological surgery(OR=14.895,95%CI:9.741-22.776,P<0.001),constipation for 20-30 years(OR= 1.412,95%CI:0.925-2.156,P=0.010)were independent risk factors for difficult colonoscopy.Conclusions:This retrospective study identified several patient-related factors that influence the technical difficulty of colonoscopy.These findings had implications for practice and teaching of colonoscopy.
RESUMO
Objective:To explore the reasonable withdrawal time at different colonic segments.Methods:It was a prospective observational study involving 465 patients who underwent colonoscopy from November 2019 to November 2020 at our endoscopy center. Colonoscopy records in our center from July 2017 to September 2017 were retrospectively analyzed as a validation set.Results:The cut-off values of withdrawal time at ascending colon, transverse colon, descending colon, and sigmoid colon and rectum determined by receiver operating characteristic (ROC) curve were 77 s, 61 s, 56 s, and 109 s, respectively. At the ascending colon, the adenoma detection rate (ADR) was significantly higher (17.3% VS 2.8%, P<0.001) when the colonoscopy withdrawal time was ≥77 s. When the withdrawal time was ≥61 s at the transverse colon (6.9% VS 2.8%, P=0.036), that over 59 s at the descending colon (6.3% VS 1.7%, P=0.019), and that ≥109 s at the sigmoid colon and rectum (31.0% VS 7.9%, P<0.001), the ADR was significantly higher. Multivariate analysis showed that withdrawal time of ≥77 s at the ascending colon ( OR=6.427, P<0.001), those ≥56 s at the descending colon ( OR=3.564, P=0.045) and ≥109 s at the sigmoid colon and rectum ( OR=5.073, P<0.001) were independent risk factors for the increase of ADR. In the validation set, when the withdrawal times at the ascending colon, the transverse colon, the descending colon, and the sigmoid colon and rectum were ≥77 s, 61 s, 56 s, and 109 s, respectively, the total ADR (48.3% VS 17.6%, OR=2.952, P<0.001) and polyp detection rate (PDR) (63.2% VS 23.0%, OR=4.191, P<0.001) significantly increased. There were no significant differences in ADR ( P=0.563) or PDR ( P=0.770) compared with those where withdrawal time was over 6 min. Conclusion:The ADR and PDR significantly increase when the withdrawal times are ≥77 s at the ascending colon, ≥61 s at the transverse colon, ≥56 s at the descending colon, and ≥109 s at the sigmoid colon and rectum.

RESUMO
Inflammatory bowel disease (IBD) is a chronic non-specific inflammatory digestive tract disease with unknown etiology. Patients with IBD are recommended to take life-long follow-up and treatment due to the long disease course and repeated recurrence of disease. With the development of ultrasound technology, trans-abdominal bowel ultrasound has been brought into focus in recent years because of its high sensitivity, specificity, free of radiation, convenience and economy. This article reviewed the characteristics of ultrasound of IBD and the application and value of trans-abdominal bowel ultrasound in IBD.
RESUMO
Objective:To explore the screening scheme of gastric cancer in large-scale natural population in Wuxi.Methods:From December 2016 to December 2019, 105 865 residents of 19 communities (villages) in six streets of Xinwu District, Wuxi were randomly enrolled in this study by random number table. A household epidemiological questionnaire survey was conducted among 50 063 target population subjects (aged 40-69), and then, respondents were divided into four categories, category Ⅰ: HP (-), PG (-); category Ⅱ: HP (+ ), PG (-); category Ⅲ: HP (+ ), PG (+ ); category Ⅳ: HP (-), PG (+ )according to the serological Helicobacter pylori ( HP) antibodies and pepsinogen (PG) test results. People in category Ⅲ and Ⅳ were all selected into group C and group D respectively, then individuals 3 times of group D were randomly selected from category Ⅰ to assign to group A, and individuals 3 times of group C from category Ⅱwere assigned to group B in the same way. Remaining individuals in category Ⅰ and Ⅱ who had first-degree family history of gastric cancer were also included in group A and group B, respectively. Endoscopic and pathological examination were performed on the above enrolled subjects for high grade intraepithelialneoplasia (HGIN), early gastric cancer and gastric cancer. Results:Of the 50 063 target subjects, 31 508 questionnaires were finally collected, with a participation rate of 62.9%. A total of 19 745 people were tested for serology, and the participation rate was 39.4% (19 745/50 063). Serological results showed that there were 11 152 people (56.48%) in category Ⅰ, 8 170 (41.38%) in category Ⅱ, 124 (0.63%) in category Ⅲ, and 299 (1.51%) in category Ⅳ. According to the exclusion criteria and principle of voluntariness, 3 400 individuals were candidates to undergo gastroscopy. Finally, a total of 2 389 people came to the hospital for gastroscopy, 1 263 in group A, 814 in group B, 86 in group C and 226 in group D, with an overall response rate of 70.3% (2 389/3 400), target population participation rate of 4.8% (389/50 063), and the overall population participation rate of 2.3% (2 389/105 865). In the 2 389 cases, there were 32 cases (1.34%) of HGIN and gastric cancer by gastroscopy and biopsy pathology, among which 1 case (3.125%) aged 40-49, 9 (28.125%) aged 50-59, and 22 (68.750%) aged 60-69. Among the 32 cases, 25 cases (78.13%)were pathologically confirmed as having HGIN or early gastric cancer by endoscopic submucosal dissection or surgical operation. By eliminating 810 people (including 3 gastric cancer) without first-degree family history with gastric cancer in group Ⅰ and Ⅱ, and increasing the gastroscopy screening age to 50 years (exluding 214 people aged 40-49, including 1 gastric cancer), the number of people who should undergo gastroscopy could be reduced from 2 389 to 1 365, and 28 cases of HGIN or gastric cancer were still detected, including 22 HGIN or early gastric cancer.Conclusion:Gastroscopy after the screening with epidemiological, serological tests, age and first-degree relative with gastric cancer family history is suitable for gastric cancer screening in Wuxi. Based on Chinese national conditions, a new community gastric cancer screening program is recommended in Wuxi considering cost-effectiveness, which includes those over 50 years old, serological PG (+ ) and first-degree relatives with family history of gastric cancer.
RESUMO
OBJECTIVES@#To investigate the relationship between the fatty acid-binding protein 4 (FABP4) and colorectal cancer (CRC).@*METHODS@#Using an enzyme-linked immunosorbent assay (ELISA), we measured the expression of FABP4 in plasma of 50 patients who underwent surgery for CRC from October 2017 to May 2018 and 50 healthy controls. The content of the visceral fat area (VFA) as seen with abdominal computed tomography (CT) scanning was measured by ImageJ software. The expression levels of FABP4, E-cadherin, and Snail proteins in CRC and adjacent tissues were determined by immunohistochemistry.@*RESULTS@#The mean concentration of plasma FABP4 of CRC patients was higher than that of the control group (22.46 vs. 9.82 ng/mL; @*CONCLUSIONS@#High LPA and VFA were risk factors for increased plasma FABP4 in CRC patients. FABP4 protein was highly expressed in CRC tissues and associated with TNM stage, differentiation, and lymph node metastasis of CRC. The level of FABP4 in CRC tissue was correlated with E-cadherin and Snail expression, suggesting that FABP4 may promote CRC progression related to epithelial-mesenchymal transition (EMT).
RESUMO
Inflammatory bowel disease(IBD)is a non-specific,chronic intestinal inflammatory disease,which mainly includes ulcerative colitis(UC)and Crohn's disease(CD). The pathogenesis of IBD is not completely clear,and is mainly related to gene,environment,dysfunction of immune system and intestinal mucosal barrier. As the first defense line of intestinal mucosal barrier,the mucus barrier plays an important role in the occurrence and development of IBD. This article reviewed the advances in study on mucus barrier in IBD.
RESUMO
Tumor microenvironment is the key factor that influences the invasion and metastasis of tumor cells.Exosome is the particle by which cells can make communication in microenvironment.MicroRNA (miRNA)is widely involved in physiological processes,and plays an important role in the stability of tumor environment.MiRNAs in exosome play roles in tumor cell proliferation,extracellular matrix remodeling,and then promote the metastasis,invasion and angiogenesis of tumor.Thus,the expression of oncogenes can be blocked by regulating the exosome production and secretion.It may shed light on the development of a thera-peutic strategy for tumor treatment.
RESUMO
MicroRNAs (miRNAs)are closely associated with the development,invasion,metastasis and prognosis of cholangiocarcinoma (CCA).The abnormal expressions of miRNA play important roles in regulating the genetic variation,cell cycle,invasion and metastasisability and apoptosis of CCA.MiRNAs are hopeful for being used as the biological markers of early diagnosis,prognosis and treatment target.

RESUMO
<p><b>OBJECTIVE</b>To investigate the expression profile of serum micro (mi)RNAs in cholangiocarcinoma (CCA) and investigate the regulatory contribution of miRNAs to the invasive and metastasis.</p><p><b>METHODS</b>Microarray analysis was carried out using serum samples collected from 30 patients with CCA, bile duct cancer tissues and the corresponding normal tissues collected from 10 patients, and serum samples from 50 healthy volunteers. The miRNAs identified as dysregulated in CCA were verified by RT-PCR. Focused analysis on miR-224 was carried out using the human CCA cell lines HCCC-9810 and RBE to investigate the role of this miRNA in IL-6 expression (using IL-6 induction), cell growth, invasiveness and metastasis (using miR-224 mimic transfection). The one-way ANOVA test was used for statistical analysis.</p><p><b>RESULTS</b>Forty-three miRNAs were dysregulated in CCA (vs. non-CCA, P<0.01), of which 22 were upregulated and 21 were downregulated. RT-PCR data showed that the miR-224 was significantly upregulated in serum as well as in cancer tissue from CCA patients. Induction of HCCC-9810 and RBE cells with IL-6 showed a time-dependent upregulation of miR-224. Furthermore, the HCCC-9810 and RBE cells transfected with miR-224 mimic showed enhanced cell growth, invasiveness and migratory ability.</p><p><b>CONCLUSION</b>IL-6 may promote the invasive and metastatic properties of CCA through upregulated miR-224. Studies of the differentially expressed serum miRNAs in CCA may help to further elucidate the pathogenic processes of this disease and aid in the development of a novel and effective therapeutic strategy.</p>

BACKGROUND/AIMS: Recent papers have highlighted the role of diet and lifestyle habits in irritable bowel syndrome (IBS), but very few population-based studies have evaluated this association in developing countries. The aim of this study was to evaluate the association between diet and lifestyle habits and IBS. METHODS: A food frequency and lifestyle habits questionnaire was used to record the diet and lifestyle habits of 78 IBS subjects and 79 healthy subjects. Cross-tabulation analysis and logistic regression were used to reveal any association among lifestyle habits, eating habits, food consumption frequency, and other associated conditions. RESULTS: The results from logistic regression analysis indicated that IBS was associated with irregular eating (odds ratio [OR], 3.257), physical inactivity (OR, 3.588), and good quality sleep (OR, 0.132). IBS subjects ate fruit (OR, 3.082) vegetables (OR, 3.778), and legumes (OR, 2.111) and drank tea (OR, 2.221) significantly more frequently than the control subjects. After adjusting for age and sex, irregular eating (OR, 3.963), physical inactivity (OR, 6.297), eating vegetables (OR, 7.904), legumes (OR, 2.674), drinking tea (OR, 3.421) and good quality sleep (OR, 0.054) were independent predictors of IBS. CONCLUSIONS: This study reveals a possible association between diet and lifestyle habits and IBS.
