| 1 | Malakoplakia of the colon associated with colonic adenocarcinoma diagnosed in colonic biopsies显示文摘Malakoplakia, typically involving the urinary tract, is an uncommon form of chronic in? ammation caused by chronic infections and characterized by accumulation of macrophages. It has also been found in many other sites such as the gastrointestinal tract, pancreas, liver, lymph nodes, skin, respiratory tract, adrenal gland, vagina and brain. We present a case of a 64-year-old man referred to our hospital with cachexia and radiologic evidence of metastatic tumor of the liver. Colonoscopy revealed a large malignant - appearing polypoid mass of the ascending colon and multiple distinct polyps throughout the rest of the colon. Biopsies of the ascending colon mass confirmed the diagnosis of adenocarcinoma. Histological examination of two of the other polyps revealed malakoplakia which was characterized by aggregates of granular histiocytes with Michaelis - Gutmann bodies and histochemically confirmed with periodic acid-Schiff and von Kossa stains. This is a rare case diagnosed on endoscopic samples. The majority of reported cases were found in surgical specimens. In addition, the endoscopic appearance of multiple polyps is unusual in malakoplakia. | F Karasavvidou SP Potamianos S Barbanis E Stathakis A Psychos AN Kapsoritakis G Koukoulis | 2007 | World Journal of Gastroenterology2007，13，45： | 2 |

| 3 | Role of autophagy in gastric carcinogenesis显示文摘Gastric cancer represents a common and highly fatal malignancy,and thus a pathophysiology-based reconsideration is necessary,given the absence of efficient therapeutic regimens.In this regard,emerging data reveal a significant role of autophagy in gastric oncogenesis,progression,metastasis and chemoresistance.Although autophagy comprises a normal primordial process,ensuring cellular homeostasis under energy depletion and stress conditions,alterations at any stage of the complex regulatory system could stimulate a tumorigenic and promoting cascade.Among others,Helicobacter pylori infection induces a variety of signaling molecules modifying autophagy,during acute infection or after chronic autophagy degeneration.Subsequently,defective autophagy allows malignant transformation and upon cancer establishment,an overactive autophagy is stimulated.This overexpressed autophagy provides energy supplies and resistance mechanisms to gastric cancer cells against hosts defenses and anticancer treatment.This review interprets the implicated autophagic pathways in normal cells and in gastric cancer to illuminate the potential preventive,therapeutic and prognostic benefits of understanding and intervening autophagy. | Apostolis Papaefthymiou Gregory Christodoulidis Apostolos Koffas Michael Doulberis Stergios A Polyzos Anastasios Manolakis Spyros Potamianos Andreas Kapsoritakis Jannis Kountouras | 2021 | World Journal of Gastrointestinal Oncology2021，13，10： | 2 |
