Objective To investigate the correlation between capsule endoscopy Crohn′s disease activity index (CECDAI ) , capsule endoscopy Lewis score , simplified Crohn′s disease activity index (sCDAI) ,C reactive protein (CRP) ,erythrocyte sedimentation rate (ESR) and Crohn′s disease (CD) activity .Methods From April 2009 to April 2014 , 120 patients having received capsule endoscopy examination and diagnosed as CD were collected . The data of CRP and ESR were analyzed . The CD severity was scored by CECDAI ,Lewis score and sCDAI .Spearman correlation was performed to analyze the correlation between CECDAI ,Lewis score ,sCDAI ,CRP and ESR .Results Among all the patients , CECDAI had a good correlation with Lewis score (r=0 .645 , P< 0 .01) and also was correlated with sCDAI (r=0 .190 , P< 0 .05) ,CRP and ESR (r= 0 .315 and 0 .393 ,both P< 0 .01) .However ,the Lewis score was not correlated with sCDAI ,CRP and ESR (r=0 .052 ,0 .041 and 0 .021 ,all P>0 .05) . sCDAI had a good correlation with CRP and ESR (r=0 .438 and 0 .429 ,both P<0 .01) .Among patients whose capsule endoscope failed to pass through the whole small intestinal ,the CECDAI had no significant correlation with sCDAI ,CRP and ESR (r=0 .126 ,0 .181 and 0 .269 ,all P>0 .05) .Conclusions Lewis score ,sCDAI ,CRP and ESR can reflect disease activity of CD patients in a certain degree .CECDAI is the most suitable index in evaluating the disease activity of CD patients .Therefore ,it is necessary to attach importance to capsule endoscopy examination .

AIM: To study the characterization of thyrotropin receptor (TSHR) and its active fragment TSHR aa352-366 as immunogens in BALB/c mice. METHODS: BALB/c mice were injected peritoneally with TSHR aa352-366-KLH (hemocyanin from keyhole limpets) and the mixture of TSHR aa352-366-KLH and guinea pig TSHR every 15 days, respectively. The levels of thyroid hormones and TSHR antibodies and TSHR mRNA were measured, and the pathological changes of thyroid tissue were observed. RESULTS: In the group injected with TSHR aa352-366-KLH, the serum levels of TT_3 and TT_4 decreased (P

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
