纳入标准: |
1.PUC纳入标准:(1)临床表现:至少持续4周出现间断或持续的腹痛、腹泻、便血,伴或不伴体重减轻、发热、贫血等全身症状。(2)电子结肠镜下表现:结直肠连续分布的糜烂、浅溃疡等,粘膜可呈颗粒状改变、质脆易出血、血管纹理消失。(3)消化道钡餐造影:肠壁见多发性小充盈缺损,结肠肠管呈铅管样。(4)病理组织学检查:炎性细胞浸润和隐窝结构改变。①隐窝结构改变包括隐窝的分支、扭曲、萎缩和黏膜表面的不规则。②炎性细胞浸润,即局灶性或弥散的基底部浆细胞增多,急慢性炎性细胞浸润于黏膜固有层,形成隐窝炎、隐窝脓肿等。满足(1)+{(2)或(3)}+(4)可以确诊 UC。 |

Inclusion criteria |
1.Inclusion criteria for PUC: (1) Clinical manifestations: intermittent or persistent abdominal pain, diarrhea, bloody stools for at least 4 weeks, with or without systemic symptoms such as weight loss, fever, anemia, etc; (2) Under electronic colonoscopy, there are continuous erosions, shallow ulcers, etc. in the colon, and the mucosa may appear granular, brittle, and prone to bleeding, with disappearance of vascular texture; (3) Gastrointestinal barium meal imaging: Multiple small filling defects are observed in the intestinal wall, and the colon intestine appears as a lead tube; (4) Pathological histology examination: inflammatory cell infiltration and changes in crypt structure; 1) .Structural changes in crypts include branching, twisting, atrophy and irregularities on the mucosal surface; 2) .Inflammatory cell infiltration, that is, focal or diffuse basal plasma cell increase, acute and chronic inflammatory cell infiltration in the lamina propria propria, forming cryptitis, crypt abscess, etc. Meeting (1)+{(2) or (3)}+(4) confirms the diagnosis of UC. 2.PCD inclusion criteria: (1) Children with recurrent abdominal pain, diarrhea, fever, or coexisting extraintestinal manifestations such as nodular erythema, gangrenous pyoderma, scleritis, uveitis, and recurrent oral ulcers; (2) Colonoscopy shows a) discontinuous lesions b) pebble like mucosa or longitudinal ulcers c) changes in whole wall inflammatory response d) non caseous granulomas e) fissures and fistulas f) anal lesions; (3) Exclude diseases such as intestinal tuberculosis, Behcet's disease, lymphoma, appendicitis, and UC. Diagnosis basis: After excluding the above diseases, a, b, and c are suspected diagnoses; Adding one of d, e, and f can confirm the diagnosis; Individuals with d, along with any two of a, b, and c, can also be diagnosed. 3.Inclusion criteria for the control group: Referring to the Rome IV diagnostic criteria for functional abdominal pain (FAP) in children: (1) episodic or persistent abdominal pain; (2) Not meeting the criteria for other functional gastrointestinal diseases (FGID); (3) No evidence of inflammatory, anatomical, metabolic abnormalities or tumors that can explain the symptoms; (4) Pain can occur at least once a week and last for at least 2 months; (5) Age range from 2 to 14 years old. |
