AIM: To investigate gastrointestinal (GI) symptoms in peritoneal dialysis (PD) patients and to explore related factors contributing to GI symptoms. METHODS: One hundred and twelve patients undergoing PD participated in the study. The gastrointestinal symptom rating scale was used for measuring GI symptoms. Information on age, height, weight, body mass index, disease leading to chronic renal failure, history of corticosteroid therapy, presence of predialytic GI symptoms, daily dosage of pills, and duration, type and daily dialysate volume of PD was obtained by interviewing patients and/or reviewing the medical records. Hemoglobin, albumin and Kt/V data were obtained from follow-up database. We used multiple regression analysis with stepwise backward variable selection to test for factors predicting GSRS scores with significance level of selection entry at 0.05 and selection of stay at 0.10. RESULTS: The prevalence of eating dysfunction, reflux and indigestion in the PD patients was 44.2%, 32.7%,32.7%, respectively. A history of corticosteroid therapy (b = 8.93, P 0.05. CONCLUSION: Eating dysfunction, reflux and indigestion were common in PD patients. Daily dosage of pills and corticosteroid history predicted GI symptoms, while residual renal function prevented them.

BACKGROUND: Recurrence of inflammation in the extrahepatic bile duct can lead to bile duct stenosis' obstructive jaundice and cavernous transformation of the portal vein. The latter can develop into extrahepatic portal hypertension (PHT). It is difficult to establish the correct method for treating these conditions. METHODS: At another hospital, a 51-year-old man developed PHT as a result of endoscopic retrograde cholangiopancreatography and endoscopic nasobiliary drainage to relieve cholelithiasis and obstructive jaundice. We dealt with the biliary tract obstruction through percutaneous transhepatic cholangial drainage (PTCD), followed by selective devascularization and a shunt operation 2 weeks after the disappearance of jaundice. Three months after cholecystojejunostomy, there were no obvious changes around the bile duct. RESULT: The patient recovered uneventfully and was discharged 14 days after operation. CONCLUSION: For this patient, surgery in stages was the best choice. The most suitable method to decrease jaundice is PTCD.

Progress in the molecular oncology of gastrointestinal carcinomas depends on high quality cancer tissues for research. Recent acceleration on new technological platforms as well as the "omics" revolution increases the demands on tissues and peripheral blood for research at the DNA, mRNA and protein levels. Tissue bank creation emerges as a priority. Tumor tissue banks are facilities that are organized to collect, store and distribute samples of tumor and normal tissue for further use in basic and translational cancer research. The samples are generally obtained immediately after excision, prior to fixation, to ensure optimal preservation of proteins and nucleic acids. It is possible for surgeons or pathologists to collect fresh tissue prospectively during their routine dissection procedures. Most tissue banks are "project-driven" tumor banks, which are specialized collections of tumor samples on which their research is based. Systematic collection of all available tumor tissue is much rarer. High quality tissue banks need the collaboration of clinicians and basic scientists, but also the informed consent of patients and ethical approval. Through the standard operation procedure, snap frozen fresh tissue collection, storage and quality control for cryopreserved tissues are the pivotal factors on tissue bank construction and maintaining. The purpose of the tissue bank creation is enhancing the quality and speed on both the basic and translational research on gastrointestinal cancer. The quality assurance and quality control are handled based on reviewing HE staining slides or touch imprint cytology by pathologists.
