Objective:To improve the understanding of the diagnosis and treatment of early T-cell precursor acute lymphoblastic leukemia (ETP-ALL).Methods:The clinical data of a patient with ETP-ALL who was misdiagnosed as peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) admitted to the Second Hospital of Lanzhou University in October 2020 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient who presented "inguinal lymphadenopathy" as the first symptom underwent lymph node biopsy and pathological examination at local hospital, and he was diagnosed as PTCL-NOS according to the consultation of another 2 hospitals. After 2 courses of chemotherapy (CHOPE regimen, GLD regimen, unknown specific medication and dosage), the therapeutic efficacy was poor. For further diagnosis and treatment, this patient came to Lanzhou University Second Hospital. Flow cytometry found blast cells in the bone marrow, and then other related examinations were completed, he was finally diagnosed as ETP-ALL. The chemotherapy regimens of Hyper-CVAD and EA were alternatively used, progressive disease (PD) occurred after 3 courses of treatment, and chidamide was added in the 4th and 5th courses of treatment, the disease still progressed, and the patient died after follow-up. The disease course of the patient was about 12 months.Conclusions:ETP-ALL has unique immunophenotypic characteristics. ETP-ALL patients have a low remission rate after conventional induction therapy, high recurrence rate and poor prognosis. Currently, there is no effective standard treatment regimen, and allogeneic hematopoietic stem cell transplantation or timely addition of new drugs may improve the prognosis.

Objective To analyze the short-term clinical efficacy and influencing factors of ustekinumab monoclonal antibody(UST)in the treatment of Crohn′s disease(CD).Methods Retrospective cohort study was used to collect the clinical data of CD patients treated with UST in the 10th People′s Hospital affiliated to Tongji University from December 2020 to October 2022.The main analysis is the short-term clinical efficacy and influencing factors of UST treatment for CD at weeks 8 and 16,And analyze the endoscopic response rate of some patients.Results A total of 91 CD patients who first used UST were included.The 8-week clinical response rate of UST treat-ment for CD was 61.5%,and the clinical response rate was 45%;The clinical response rate at 16 weeks was 71.4%,and the clinical response rate was 54.9%.56 cases underwent endoscopic re-examination in our hospital,and the endoscopic response rate at 16 weeks was 41.1%.Univariate analysis showed that fistula(including anal fistula,personal history of anal fistula,and intestinal skin fistula)is associated with clinical remission in Crohn′s disease patients at 8/16 weeks.Further multivariate COX regression analysis showed that the presence of a history of anal fistula surgery was an independent protective factor affecting clinical remission in CD patients treated with UST at 8 weeks(HR = 0.04,95%CI:0.00~0.38;P = 0.005)and 16 weeks(HR = 0.04,95%CI:0.01~0.34;P = 0.003)compared to those without fistula;Narrow lesions are an independent risk factor for 16 week clinical remission in CD patients compared to non-narrow and non-penetrating lesions(HR = 1.75,95%CI:1.08~2.84;P = 0.023).No patients were found to have stopped medication due to serious adverse reactions.Conclusions UST can improve the clinical remission and response of CD patients at 8/16 weeks,and has good short-term clinical efficacy.CD patients with a personal history of anal fistula are recommended to use UST monoclonal antibodies,while patients with stenotic lesions should be cautious in using UST monoclonal antibodies.Whether the patient has undergone surgical treatment in the past,as well as whether UST has been used on the first or non-first line,has no significant impact on clinical remission.
