    ABSTRACT: AIM: To analyze tumor regression grade (TRG) for prognosis of locally advanced rectal adenocarcinoma (LARA) treated with preoperative radiotherapy. METHODS: One hundred and ninety patients with clinical stage II/III LARA were studied. All patients underwent radical surgery (between 2004 and 2010) after 30-Gy/10-fraction preoperative radiotherapy (pre-RT). All 190 patients received a short course of pre-RT and were reassessed for disease recurrence and survival; the slides of surgical specimens were reviewed and classified according to Mandard TRG. We compared patients with good response (Mandard TRG1 or TRG2) vs patients with bad/poor response (Mandard TRG3-5). Outcomes evaluated were 5-year overall survival (OS), 5-year disease-free survival (DFS), and local, distant and mixed recurrence. Fisher's exact test or χ(2) test, log-rank test and proportional hazards regression analysis were used to calculate the probability that Mandard TRG was associated with patient outcomes. RESULTS: One hundred and sixty-six of 190 patients (87.4%) were identified as Mandard bad responders (TRG3-5). High Mandard grade was correlated with tumor height (41.7% < 6 cm vs 58.3% ≥ 6 cm, P = 0.050), ypT stage (75% ypT0-2 vs 25% ypT3-4, P = 0.000), and ypN stage (75% ypN0 vs 25% ypN1, P = 0.031). In univariate survival analysis, Mandard grade bad responders had significantly worse OS and DFS than good responders (TRG1/2) (OS, 83.1% vs 96.4%, P = 0.000; DFS, 72.3% vs 92.0%, P = 0.002). In multivariate survival analysis, Mandard bad responders had significantly worse DFS than Mandard good responders (DFS 3.8 years (95%CI: 1.2-12.2 years, P = 0.026). CONCLUSION: Mandard grade good responders had a favorable prognosis. TRG may be a potential predictor for DFS in LARA after pre-RT.

    ABSTRACT: The high mobility group box 1 (HMGB1), which belongs to the subfamily of HMG-1/-2, is a highly conserved single peptide chain consisting of 215 amino acid residues with a molecular weight of approximately 24894 Da. HMGB1 is a ubiquitous nuclear protein in mammals and plays a vital role in inflammatory diseases. Acute pancreatitis is one of the most common causes of acute abdominal pain with a poor prognosis. Acute pancreatitis is an acute inflammatory process of the pancreas (duration of less than six months), for which the severe form is called severe acute pancreatitis (SAP). More and more studies have shown that HMGB1 has a bidirectional effect in the pathogenesis of SAP. Extracellular HMGB1 can aggravate the pancreatic inflammatory process, whereas intracellular HMGB1 has a protective effect against pancreatitis. The mechanism of HMGB1 is multiple, mainly through the nuclear factor-κB pathway. Receptors for advanced glycation end-products and toll-like receptors (TLR), especially TLR-2 and TLR-4, are two major types of receptors mediating the inflammatory process triggered by HMGB1 and may be also the main mediators in the pathogenesis of SAP. HMGB1 inhibitors, such as ethyl pyruvate, pyrrolidine dithiocarbamate and Scolopendra subspinipes mutilans, can decrease the level of extracellular HMGB1 and are the promising targets in the treatment of SAP.

    ABSTRACT: Bleeding of peptic ulcer at the posterior duodenal bulb still is a particular endoscopic challenge with increased risk of treatment failure and worse outcome. In this article, we report successful treatment of an actively bleeding peptic ulcer located at the posterior duodenal wall, using an over-the-scope-clip in the case of a 54-year-old male patient with hemorrhagic shock. Incident primary hemostasis was achieved and no adverse events occurred during a follow-up of 60 d.

    ABSTRACT: To investigate the interaction between Xiaotan Sanjie (XTSJ) decoction and interleukin-8 (IL-8) and its effect on adhesion, migration and invasion of SGC-7901 gastric cancer cells. SGC-7901 gastric cancer cells were exposed to serum containing XTSJ decoction and/or IL-8 (1 ng/mL). SGC-7901 cell adhesion to fibronectin, an extracellular matrix component, was detected using the Cell Counting Kit-8. Migration and invasion abilities of SGC-7901 cells were detected by scratch wound and Transwell chamber assays. Then, protein (immunofluorescence and Western blot) and mRNA levels (quantitative polymerase chain reaction) of cluster of differentiation 44 (CD44), a cell adhesion molecule, were measured in 72-h-cultured SGC-7901 cells. Cell adhesion was promoted by IL-8 (P = 0.001), but was inhibited by XTSJ decoction (P = 0.0001). Similarly, IL-8 promoted SGC-7901 cell invasion (P = 0.003), and XTSJ decoction inhibited cell invasion (P = 0.001). IL-8 induced SGC-7901 cell migration, but this was inhibited by XTSJ decoction. IL-8 up-regulated CD44 protein (P = 0.028) and mRNA expression (P = 0.002), whereas XTSJ decoction inhibited CD44 protein expression (P = 0.0001), but not mRNA expression (P = 0.275). An interaction between XTSJ decoction and IL-8 was confirmed in the invasion (P = 0.001) and CD44 mRNA expression of SGC-7901 cells (P = 0.010), but not in cell adhesion (P = 0.051). XTSJ decoction may inhibit adhesion, migration and invasion of gastric cancer cells, which is partly associated with down-regulation of IL-8.

    ABSTRACT: To review the underlying pathophysiology and currently available treatments for pruritis associated with jaundice. English language literature was reviewed using MEDLINE, PubMed, EMBASE and clinicaltrials.gov for papers and trails addressing the pathophysiology and potential treatments for pruritis associated with jaundice. Recent advances in the understanding of the peripheral anatomy of itch transmission have defined a histamine stimulated pathway and a cowhage stimulated pathway with sensation conveyed centrally via the contralateral spinothalamic tract. Centrally, cowhage and histamine stimulated neurons terminate widely within the thalamus and sensorimotor cortex. The causative factors for itch in jaundice have not been clarified although endogenous opioids, serotonin, steroid and lysophosphatidic acid all play a role. Current guidelines for the treatment of itching in jaundice recommend initial management with biliary drainage where possible and medical management with ursodeoxycholic acid, followed by cholestyramine, rifampicin, naltrexone and sertraline. Other than biliary drainage no single treatment has proved universally effective. Pruritis associated with jaundice is a common but poorly understood condition for which biliary drainage is the most effective therapy. Pharmacological therapy has advanced but remains variably effective.

    ABSTRACT: Since its introduction in 2001 capsule endoscopy opened up the small bowel for diagnostic approaches followed by double balloon enteroscopy which enabled the endoscopic community to perform therapeutic interventions in the whole small intestine. In this review the scientific developments related to indications, diagnostic yield and complications of the last years between the competing devices double ballon enteroscopy, single balloon enteroscopy and spiral enteroscopy are illustrated.

    ABSTRACT: To investigate the presence of human papillomavirus (HPV) DNA along with the integration, the quantification and the expression of the HPV16 in colorectal cancers. A prospective series of colorectal tumors were genotyped for HPV DNA. The clinical and pathological variables of the HPV-positive tumors were compared to those of HPV-negative samples. The integration status of HPV16 was evaluated by calculating E2/E6 ng ratios. HPV16-positive tumors were also evaluated for (1) E2, E4, E5, E6 and E7 viral gene ng quantification; (2) relative quantification compared to W12 cells; and (3) viral E2, E4, E5, E6 and E7 mRNA transcripts by real-time polymerase chain reaction. HPV infection was detected in 16.9% of all tumors examined, and HPV16 was the most frequent type detected (63.6% of positive tissues). Notably, the clinical and pathological features of HPV-positive colorectal cancers were not significantly different than those of HPV-negative cancers (χ (2) and t-test for all clinical and pathological features of HPV-positive vs HPV-negative colorectal cancers: p ns). HPV16 DNA was present exclusively in episomal form, and the HPV16 E2, E4, E5, E6 and E7 genes were detected in trace nanogram quantities. Furthermore, the HPV16 genes ranged from 10(-3) to 10(-9) compared to W12 cells at an episomal stage. Although the extractions were validated by housekeeping gene expression, all the HPV16 positive tissues were transcriptionally inactive for the E2, E4, E5, E6 and E7 mRNAs. Based on our results, HPV is unlikely involved in colorectal carcinogenesis.
