Iron deficiency anemia (IDA) is one of the common complications of inflammatory bowel disease (IBD) . Oral iron supplement is a commonly used treatment for IDA, and its role in IBD patients with IDA has always been controversial. There are problems such as oral iron intolerance and poor absorption in IBD patients. Studies showed that oral iron would increase the disease activity index in IBD patients, which may be related to oxidative stress induced by intestinal iron and change the composition of intestinal flora. This article summarizes the diagnostic criteria and treatment of IBD with IDA, explores the advantages and disadvantages of oral iron supplement and the treatment controversy, and puts forward iron supplement strategy.

Objective To investigate the value of magnetic resonance diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) in detection of central gland prostate cancer (CGPCa).Methods Routine MRI and DWI examination were performed in 25 CGPCa patients and 30 benign prostate heperplasia (BPH) patients.Then the ADC value was measured according to the image of the lesion after DWI,and the receiver op erating characteristic (ROC) curve was analyzed to select the best ADC value for diagnosis of CGPCa.Results The ADC value of CGPCa (0.89±0.12×10-3 mm2/s) was smaller than that of BHP (1.43±0.12x10-3 mm2/s),and the dif ference was statistically significant (P＜0.05).When the cut off point of ADC value was set at 1.192×10-3 mm2/s,the sensitivity was 80.0％ and the specificity was 85.0％.Conclusion DWI and ADC have clinical application value in diagnosis of CGPCa.
