Objective To investigate the clinical features of cryptogenic multifocal ulcerous stenosing enteritis(CMUSE),and to improve the diagnosis of this rare disease.Methods From 2010 to 2015,clinical data of 10 patients with CMUSE were retrospectively analyzed,including clinical features,laboratory examination,imaging examination,appearance under endoscopy,pathologic characteristics,location of lesions,treatment and prognosis.Results Among the 10 patients with CMUSE (male six,female four),the mean age was (35.1±14.8) years.The predominant clinical manifestation was melena (eight cases),abdominal pain (eight cases) and anemia (nine cases).The results of laboratory examination showed normal in erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP).Among seven patients,hypersensitive C reactive protein (hsCRP) of two patients increased.Imaging examination showed intestinal stricture and appearance under endoscopic examination was intestinal ulcers and stenosis.Pathologic finding was superficial ulcers at mucosal and submucosal layers.Lesions mostly involved small intestine,and one case involving ileocecal valves and rectum.Among the 10 patients,seven patients received combination of surgical resection and prednisone treatment,and three patients were only administrated with medications.After treatment,seven patients remainedremission and three patients relapsed after remission.Immunosuppressors and enteral nutrition was effective in two of them and glucocorticoid resistance happened in one patient.Conclusions The diagnosis of CMUSE should he considered in patients with unexplained recurrent bowel obstruction,melena,anemia and concomitant intestinal ulcer and stricture.Endoscopy plays an important role in the diagnosis.Glueocorticoid is effective but easy to relapse.Immunomodulators and enteral nutrition may be considered as second-line therapy.

Background and purpose:Inhibitor of apoptosis-stimulating protein of p53 (iASPP) is one of the ASPP family. It binds to p53 to inhibit the transcriptional activity of p53-target genes and cell apoptosis, which is asso-ciated with tumor formation. Previously, we found a new subtype of iASPP, iASPP splice variant (iASPP-SV), which is a nuclear protein containing 407 amino acid residues and can bind to p53, inhibiting p53 transcriptional activity. However, the relationship of iASPP-SV and breast cancer is still obscure. Therefore, the purpose of this research was to study the role of iASPP-SV on breast cancer tumorigenesis and progression.Methods:5’-rapid ampliifcation of cDNA ends (RACE) was used to identify the 5’-end of iASPP-SV mRNA in MCF-7 cells. HEK 293 cells were transfected with pFLAG-iASPP-SV and pFLAG-iASPP (828). Then Western blot was used to identify whether endogenous iASPP-SV was expressed in HEK 293 cells and 8 types of human tumor cell lines. This study established the stable clones of NIH 3T3 expressing FLAG-iASPP-SV and FLAG-iASPP (828). Cell proliferation assay, colony formation and soft agar colony formation assay were used to identify whether iASPP-SV and iASPP (828) can promote cell proliferation and iASPP-SV is an oncogene. Real-time lfuorescent quantitative polymerase chain reactive (RTFQ-PCR) was used to de-tect the levels of iASPP-SV and iASPP (828) mRNA in primary breast cancers. Luciferase assays were used to identify the relationships between iASPP-SV, iASPP (828), p53 and NF-κB p65.Results:The study identiifed that iASPP-SV was encoded by previously reported NF-κB p65 subunit (RelA)-associated inhibitor (RAI), and endogenously expressed in many human cancer cell lines. Analysis of cell proliferation, colony formation assay and soft agar assay for colony formation identiifed that similarly to iASPP (828), iASPP-SV promoted tumor cell proliferation and acted as an onco-gene. RTFQ-PCR result showed that the median values of iASPP-SV and iASPP (828) in breast cancers with wild-type p53 were more signiifcantly over-expressed than those of mutant p53. Luciferase assays showed that iASPP-SV and iASPP (828) could suppress NF-κB p65 transcriptional activity. Thus iASPP family may participate in the regulation of p53 and NF-κB activity, which imply that iASPP perhaps shows pro- or anti-survival activities when it interacts with different proteins.Conclusion:These ifndings indicate that iASPP-SV may be a potential target for breast cancer thera-py.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive and lethal human cancers. Cur-rent studies on the relationship between complicated type 2 diabetes mellitus (T2DM) and PDAC prognosis have demonstrated inconsis-tent results. The present study aimed to determine the relationship between complicated T2DM and the clinicopathological characteris-tics of PDAC, and evaluate whether complicated T2DM is a significant predictor for overall survival in patients with resectable PDAC. Methods: In this study, clinicopathological characteristics were observed in 136 patients who underwent surgery for PDAC at the Shengjing Hospital of China Medical University between January 2009 and February 2011. The relationship between complicated T2DM and overall survival of PDAC patients was analyzed using univariate and multivariate analyses. Results:The median age of pa-tients was 60 years (range: 35-80 years). Among the 136 patients, 76(55.9%) were male. The prevalence of complicated T2DM was 27.9%in 136 PDAC cases. Preexisting T2DM was not associated with any of the clinicopathological characteristics (all P>0.05). Uni-variate analysis showed that complicated T2DM (P=0.045), maximum diameter (P=0.011), histological differentiation (P=0.013), pT stage (P=0.034), vessel invasion (P=0.032), and pTNM stage (P=0.030) were significantly associated with the overall survival of PDAC patients. The median overall survival time was 14.2 months for T2DM patients, and 18.8 months for non-T2DM patients. In mul-tivariate analysis, complicated T2DM [hazard ratio (HR), 1.873;95%confidence interval (CI), 1.187-2.954;P=0.007], poorly differenti-ated tumor (HR, 2.647;95%CI, 1.413-4.957;P=0.002), and maximum diameter≥4.0 cm (HR, 1.699;95%CI, 1.094-2.640;P=0.018) were the independent predictors associated with poor overall survival. Conclusion:Complicated T2DM was associated with poor prog-nosis. It could be used as a prognostic predictor in patients with resectable PDAC. If confirmed, these findings may provide a novel ap-proach for individualized adjuvant therapy.
