AIM： To examine whether trans-10,cis-12 CLA （t10C12） or cis-9,trans-11 CLA （c9t11） inhibits heregulin （HRG）-β- stimulated cell growth and HRG-β-ErbB3 signaling in HT-29 cells. METHODS： We cultured HT-29 cells in the absence or presence of the CLA isomers and/or the ErbB3 ligand HRG-β. MTT assay, [^3H]thymidine incorporation, Annexin V staining, RT-PCR, Western blotting, immunoprecipitation, and in vitro kinase assay were performed. RESULTS： HRG-β increased cell growth, but did not prevent DNA t10c12-induced growth inhibition. T10C12 inhibited DNA synthesis and induced apoptosis of HT-29 cells, whereas c9t11 had no effect. T10c12 decreased the levels of ErbB1, ErbB2, and ErbB3 proteins and transcripts in a dose-dependent manner, whereas c9t11 had no effect. Immunoprecipitation/ Western blot studies revealed that t10c12 inhibited HRG- β-stimulated phosphorylation of ErbB3, recruitment of the p85 subunit of phosphoinositide 3-kinase （PI3K） to ErbB3, ErbB3-associated PI3K activities, and phosphorylation of Akt. However, c9t11 had no effect on phospho Aid： levels. Neither t10c12 nor c9t11 had any effect on HRG-β-induced phosphorylation of ERK-1/2. CONCLUSION： These results indicate that the inhibition of HT-29 cell growth by t10c12 may be induced via its modulation of ErbB3 signaling leading to inhibition of Akt activation.

Background: Location of death has been used to examine an indicator for good death. This study aims to examine location of death among patients with three major cancers (gastric, liver, and lung) and other factors associated with location of death in South Korea. Methods: We selected the medical and pharmacy claims data for health services and location of death among the 42,596 decedents with cancer (lung 16,632, liver 15,872, gastric 10,092) from 2009 to 2013. We used logistic regressions to identify factors associated with home death. Outcome measures are locations of death (hospital, outpatient clinics or emergency room and home). Results: Only 8.9% died at home whereas 46.5% died in hospital as inpatients. Patients with more than one comorbid cancer or receivers for any supportive care were significantly more likely to die in hospital. Female and younger than 55 years old liver cancer patients were associated with home death. Patients living in metropolitan area, or paying more insurance premium, or being public aid beneficiaries, were associated with home death. Conclusions: The supportive care service use prior to death was significantly associated with increasing odds to hospital death. Being older than 75, or having multiple cancers was significant factors associated with hospital death, whereas living in metropolitan area, lower income or emergency visit were significant factors with home death. These findings are opposite to what is found, as the palliative care and hospice is predominantly hospital-centered. The findings emphasize a need to available end-of-life care in community for dying patients.

AIM:To investigate the predictive factors of selfexpandable metallic stent patency after stent placement in patients with inoperable malignant gastroduodenal obstruction. METHODS:A total of 116 patients underwent stent placements for inoperable malignant gastroduodenal obstruction at a tertiary academic center. Clinical success was defined as acceptable decompression of the obstructive lesion within the malignant gastroduodenal neoplasm. We evaluated patient comorbidities and clinical statuses using the World Health Organization's scoring system and categorized patient responses to chemotherapy using the Response Evaluation Criteria in Solid Tumors criteria. We analyzed the relationships between possible predictive factors and stent patency. RESULTS:Self-expandable metallic stent placement was technically successful in all patients(100%),and the clinical success rate was 84.2%. In a multivariate Cox proportional hazards model,carcinoembryonic antigen(CEA) levels were correlated with a reduction in stent patency [P = 0.006; adjusted hazard ratio(a HR)= 2.92,95%CI:1.36-6.25]. Palliative chemotherapy was statistically associated with an increase in stent patency(P = 0.009; a HR = 0.27,95%CI:0.10-0.72).CONCLUSION:CEA levels can easily be measured at the time of stent placement and may help clinicians to predict stent patency and determine the appropriate stent procedure.

AIM To assess the performance of proposed scores specific for acute-on-chronic liver failure in predicting shortterm mortality among patients with alcoholic *** We retrospectively collected data from 264 patients with clinically diagnosed alcoholic hepatitis from January to December 2013 at 21 academic hospitals in Korea. The performance for predicting short-term mortality was calculated for Chronic Liver FailureSequential Organ Failure Assessment(CLIF-SOFA), CLIF Consortium Organ Failure score(CLIF-C OFs), Maddrey'sdiscriminant function(DF), age, bilirubin, international normalized ratio and creatinine score(ABIC), Glasgow Alcoholic Hepatitis Score(GAHS), model for end-stage liver disease(MELD), and *** Of 264 patients, 32(12%) patients died within 28 d. The area under receiver operating characteristic curve of CLIF-SOFA, CLIF-C OFs, DF, ABIC, GAHS, MELD, and MELD-Na was 0.86(0.81-0.90), 0.89(0.84-0.92), 0.79(0.74-0.84), 0.78(0.72-0.83), 0.81(0.76-0.86), 0.83(0.78-0.88), and 0.83(0.78-0.88), respectively, for 28-d mortality. The performance of CLIF-SOFA had no statistically significant differences for 28-d mortality. The performance of CLIF-C OFs was superior to that of DF, ABIC, and GAHS, while comparable to that of MELD and MELD-Na in predicting 28-d mortality. A CLIF-SOFA score of 8 had 78.1% sensitivity and 79.7% specificity, and CLIF-C OFs of 10 had 68.8% sensitivity and 91.4% specificity for predicting 28-d *** CLIF-SOFA and CLIF-C OF scores performed well, with comparable predictive ability for short-term mortality compared to the commonly used scoring systems in patients with alcoholic hepatitis.
