A novel nomogram for predicting endoscopic remission in refractory Crohn's disease with ustekinumab administration.

Ustekinumab (UST) is a human IgG1 monoclonal antibody that targets to the share p40 subunit of interleukin-12(IL-12) and IL-23. Evidence has shown that UST therapy is well tolerated and effective in inducing clinical response in refractory CD(Crohn's disease) and dose escalation is effective in recapturing response in over half of the patients. However, no predictive factor has been reported to be helpful for UST treatment in clinical practice. Additionally, there were few reports about therapeutic drug monitoring (TDM) of UST administration in China due to its late launch time in Chinese market and lack of experience in clinical use. Herein, we establish and validate the first UST-trough concentrations (TCs) -related nomogram in China for predicting endoscopic remission in refractory CD to facilitate clinical decision making.

The First Case of Cribriform-Morular Thyroid Carcinoma and FAP with APC Gene Mutation in China: A Case Report and Brief Review.

The cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC) is now designated as morular cribriform thyroid carcinoma (CMTC) according to the 5th edition of the World Health Organization (WHO) Classification of Thyroid Tumors. CMTC can appear within a familial adenomatous polyposis (FAP) or be sporadic. We report the first case of a young female patient in China who was diagnosed with FAP and CMTC with a mutation in exon 16 of the APC gene underlying the disease. The main purpose of this case report is to provide a special pathological type of thyroid tumors, which is expected to be helpful for clinical work in the future.
