Haiming Fang, M.D., Ph.D., Chief Physician, Associate Professor, and Master Supervisor at Anhui Medical University, Department of Gastroenterology, the Second Hospital of Anhui Medical University. I possess expertise in the diagnosis and treatment of prevalent and frequently-occurring gastrointestinal disorders, along with extensive clinical proficiency in managing complex and challenging digestive system conditions. I have conducted research on the field of gut microbiota and fecal microbiota transplantation (FMT) in China, and successfully implemented the first clinical treatment case of FMT in Anhui Province, China. My clinical expertise lies in the field of minimally invasive diagnostic and therapeutic endoscopy, with a particular focus on advanced endoscopic resection techniques such as endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), for the precise removal of digestive tract polyps, precancerous lesions, early-stage cancers, and submucosal tumors. Additionally, I specialize in peroral endoscopic myotomy (POEM) for cardiac achalasia and the endoscopic treatment of esophageal fundus varices in cirrhosis. I have pioneered the utilization of endoscopic full-thickness resection (EFTR) combined with a purse-string suture strategy for the management of postoperative fistulas, and expertise in endoscopic hemostasis, dilation of gastrointestinal stenosis, endoscopic ligation of internal hemorrhoids, endoscopic retrograde appendicitis treatment (ERAT), as well as Endoscopic therapy for weight management and small intestine endoscopy diagnosis and treatment techniques. I have authored and published over 30 papers, with 16 of them appearing in SCI-indexed journals, where I am credited as the first author or corresponding author. The publications on FMT and gut microbiota have been cited by several authoritative publications, including the "APAC Consensus on Fecal Microbiota Transplantation for Gastrointestinal Diseases," the "2020 ECCO/ESPGHAN Guidelines for the Pharmacological Treatment of Crohn's Disease in Children," the "Chinese Expert Consensus on the Clinical Application of Microecological Modulators (2020 Edition)," and the "AGA Clinical Practice Guideline for the Application of Fecal Microbiota Transplantation in Specific Gastrointestinal Disorders (2024 Edition). The total number of citations for previous publications exceeds 339. H-H-index: 8.

Full Membership of SIGMA XI. Advanced research on intestinal microecology and fecal microbiota transplantation, innovative technological advancements in endoscopic diagnosis and treatment, and the integration of medicine with engineering. I have conducted research on the field of gut microbiota and fecal microbiota transplantation (FMT) in China, and successfully implemented the first clinical treatment case of FMT in Anhui Province, China. In additional, I have firstly pioneered the utilization of endoscopic full-thickness resection (EFTR) combined with a purse-string suture strategy for the management of postoperative fistulas. The integration of endoscopic diagnosis and treatment with technological innovation in medicine and engineering is something that I find particularly fascinating. The advanced exploration of intestinal microecology and fecal microbiota transplantation, innovative technological advancements in endoscopic diagnosis and treatment, as well as the integration of medicine with engineering, are subjects that captivate my interest.
