Objective To evaluate the clinical effect of restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) for refractory ulcerative colitis (UC).Methods In this study 60 refractory UC patients received IPAA operation during the period of 1990 to 2010.Data were collected regarding early and late postoperation complications,anal continence function,and characteristics of feces.The patients' quality of life was objectively accessed using the Clevend Global Quality of Life (CGQL)index.0ne-way analysis of variance was used.Results Mean follow-up period was 2 years.Early postoperative complication rate developed in 15% (9/60),including abdominal or pelvic infection,anastomotic leak,pouch bleeding,pouch-vaginal fistula,and intestinal obstruction.Late postoperative complication rate was 12% (7/60),including pouchitis,intestinal obstruction,and male sexual dysfunction.Stool frequency per 24 hours and that at night was 3.5 ± 1.3 and 1.4 ±0.6.93% (56/60)patients differentiated gas and feces well and 3% (2/60) needed daily pads.According to Kirwan Grading Scale,anal function outcomes were Grade Ⅰ:54 (90%),Grade Ⅱ:4 (7%),and Grade Ⅲ:2 (3%).According to Bristol Stool Form Scale,characteristics of feces were Grade Ⅳ:31 (52%),Grade Ⅴ:25(42%),and Grade Ⅵ:4 (6%).Postoperative CGQL result showed a much better quality of life than preoperative CGQL (F =12.368,P < 0.05).Conclusions Refractory UC is surgically indicated and IPAA is the operation of choice with safety,satisfactory long-term outcome and improved quality of life.
5. Expression and Significance of ICOS in Colorectal Cancer
Chinese Journal of Gastroenterology 2019;24(6):335-339
Background: Inducible T-cell co-stimulator (ICOS)is a member of the B7-CD28 family, which plays roles in various biological processes including cell proliferation, differentiation and immune responses, and is closely related to immune escape in many malignant tumors. Aims: To investigate the expression and significance of ICOS in colorectal cancer (CRC). Methods: Thirty-two pairs of fresh CRC tissues and adjacent non-cancerous tissues, as well as 211 cases of paraffin-embedded CRC tissues were collected for detection of ICOS mRNA and protein expressions by real-time PCR and immunohistochemistry, respectively. Correlations between ICOS expression and clinicopathological characteristics and prognosis were analyzed. Results: In comparison with adjacent non-cancerous tissues, expression of ICOS was significantly lower in CRC tissues (P<0.05), and correlated negatively with the tumor size, serum CEA, lymph node metastasis, distal metastasis and TNM staging (P all <0.05). No significant difference in ICOS expression was found in tumors from different location (P>0.05). Kaplan-Meier survival analysis suggested a poorer prognosis in CRC patients with lower ICOS expression (P<0.05). Multivariate Cox regression analysis confirmed that ICOS expression could be an independent prognostic factor for CRC (HR=0.821, 95% CI: 0.588-0.912, P=0.034). Conclusions: ICOS is lowly expressed in CRC tissues and is associated with tumor progression and poor prognosis. It might be a promising molecular marker for predicting prognosis of CRC.

Objective To establish the rat model of collagen-induced arthritis and study the diagnostic value of MRI for early RA by comparing to pathological changes. Methods Thirty Wistar rats were randomly divided into normal groups and experimental groups.Fifteen rats of the experimental groups were immunized with type Ⅱ collagen and Freund's Adjuvant Incomplete. At the scheduled days, the selected rats of both experimental and normal groups underwent X-ray, 1.5T MR scan plus enhancement and histological analysis. Results Arthritis Index increased on the 14th day after immunization and reached the peak on the 28th day in the experimental group, the positivity of Anti-CⅡ antibody was significantly different from the normal group.The experiemental model was established in 93.33% of all rats. The enhanced MRI showed that 12 (12/15) rats presented with abnormal signs . The sensitivity of MRI was 85.71% and the specificity was 100%. There was no significant correlation could be found between MRI and histological changes X-ray revealed soft tissue swollen in 4 (4/15) rats, which showed that MRI had higher sensitivity in detecting abnormal signs of arthritis than X-ray. Conclusion MRI may be used in the early diagnosis of early RA.
