Objective To assess the value of 64-slice computer tomography used in the preoperative evaluation of rectal cancer to predict the operative procedures. Methods There were 51 pathologically proven rectal cancer patients recruited, undergoing multi-slice computer tomagraphy (MSCT) assessment preoperatively. Preoperative MSCT stage and predictive operative procedures were recorded to compare with postoperative pathological stage and practical operative procedures. Kappa Coefficient for Diagnosis Coherence and Spearman correlation analysis were performed. Results The overall accuracy of CT-TNM stages were 74.5% which led to high coherence to pathological TNM stage ( Kappa value = 0.658,P=0.000). The univariate analysis showed that distance from tumor to dentate line (F = 3.386, P =0.042 ) and tumor thickness (F = 4.542, P = 0.016) was a statistically risk factor for operative procedures. Moreover, the significant correlation between tumor thickness (cc =0.319, P =0.023 ), as well as CT-M stage (cc = 0.369, P = 0.008) and CT-TNM stage ( cc = 0.365, P = 0. 008), and operative procedures was observed, by means of conducting Spearman correlation. The possibility of developing palliative stoma was 75%, when sufficing both CT-MI stage and tumor thickness ≥20 mm; The possibility of performing sphincter sparing radical operation reached 86% when both CT-T stage < 4 and distance from tumor to dentate line were referred by MSCT. Conclusion The objective parameters influencing development of operative procedures, involving tumor thickness, CT-M stage and CT-T stage, can be rendered by MSCT preoperative assessment, which served as valuable reference for clinical decision of operative procedures in retal cancer.

ObjectiveTo explore the effects of enteral nutrition (EN) on intestinal permeability in patients with active ulcerative colitis (AUC). MethodsTwenty-four A UC patients were randomly divided into two groups:routine treatment group (n =11 ) and routine treatment plus EN group (n =13). Patients in routine treatment group were treated with mesalazine as well as low-residue diet, while patients in routine treatment plus EN group received mesalazine and short peptide EN for 14 days. The ratio of lactulose to mannitol in urine (L/M) before and after treatment was detected by high-performance liquid chromatography. ResultsThe L/M ratio was 0. 039 ± 0. 025 in routine treatment group and 0.072 ± 0.019 in routine treatment plus EN group (P =0.069). After 2 weeks of treatment, the L/M ratio of routine treatment plus EN group (0.038 ± 0.012 ) was significantly lower than the pretreatment level (P =0.043 ), while the L/M ratio of routine treatment group between before and after treatment had no significant difference (0.039 ± 0.025 vs. 0.032 ± 0.022, P =0.730). ConclusionEN can effectively improve the intestinal permeability in AUC patients.

Background::Non-alcoholic fatty liver disease (NAFLD) and inflammatory bowel disease (IBD) have shown similar worsening epidemic patterns globally and shared various overlapping pathophysiological mechanisms. However, evidence on the relationship between NAFLD and IBD risk is lacking. We aimed to investigate the associations between long-term risk of incident IBD and NAFLD in a large prospective cohort.Methods::Participants from the United Kingdom Biobank cohort (https://biobank.ndph.ox.ac.uk/) who were free of IBD and alcoholic liver disease at baseline were enrolled. Baseline non-alcoholic fatty liver degree was measured by the well-established fatty liver index (FLI). The outcomes of interest included incident IBD, ulcerative colitis (UC), and Crohn’s disease (CD). Multivariable Cox proportional hazard regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs).Results::Among 418,721 participants (mean FLI: 48.11 ± 30.11), 160,807 (38.40%) participants were diagnosed as NAFLD at baseline. During a median of 12.4 years’ follow-up, 2346 incident IBD cases (1545 UC, 653 CD, and 148 IBD-unclassified) were identified. Due to limited events, those IBD-unclassified were combined in UC or CD when examining the associated risk of UC or CD, separately. Compared with the lowest quartile of FLI, the highest quartile showed a separately 36.00%, 25.00%, and 58.00% higher risk of incident IBD (HR Q4 vs. Q1 =1.36, 95% CI: 1.19-1.55, Ptrend <0.001), UC (HR Q4 vs. Q1 =1.25, 95% CI: 1.07-1.46, Ptrend=0.047), and CD (HR Q4 vs. Q1 =1.58, 95% CI: 1.26-1.97, Ptrend <0.001) after multivariable adjustment. Compared with non-NAFLD, NAFLD participants had a significantly higher risk of incident IBD (HR=1.13, 95% CI: 1.04-1.24) and CD (HR =1.36, 95% CI: 1.17-1.58). Conclusions::Higher degree of non-alcoholic fatty liver is associated with increased risk of incident IBD. Interventions aimed at improving NAFLD may be a potential targeted strategy for the detection and treatment of IBD.
