The study focused on how to improve the diagnostic coincidence rate of patients with gallbladder stones and gallbladder cancer based on an optimized Segnet network algorithm and the relationship of gallbladder cancer with multiple tumor suppressor 1 (P16). 300 patients diagnosed with gallbladder cancer in the hospital were selected as the research subjects. The pyramid pooling operation was incorporated into the original Segnet network algorithm, and its performance was evaluated, factoring into the intersection of union (IoU), algorithm precision (Pre), and recall rate (Recall).

Bioinformatics analysis verified PVT1 expression in tumor and normal tissues. Quantitative PCR and western blotting were used to measure mRNA and protein levels, respectively.

The nonviral minicircle DNA (mcDNA) is safer for patients, cheaper to produce, and may be a more suitable technique to generate CAR T cells. In this study, we produced mcDNA-based CAR T cells specifically targeting prostate stem cell antigen (PSCA; mcDNA-PSCA-CAR T cells).

Materials & Methods: Separated CD34 stem cells from cord blood were cultured for 30 days, and the resultant DCs (CD34-DCs) were collected. The basic function of the CD34-DCs and the cytotoxicity of CD34-cytotoxic-T lymphocytes (CTLs) were tested in vitro, and tumor inhibition in a humanized NSG mouse tumor model was observed.
A 71-year-old woman presented with acute monocytic leukemia with lymphoma-like morphologic features and an unusual complex karyotype. Bone marrow (BM) aspiration revealed acute monocytic leukemia with lymphoma-like morphologic features. Thus, we called the condition a lymphoma presentation.

In this study, we knocked out (KO) PD-1 in cytotoxic T lymphocytes (CTLs) using CRISPR-Cas9 system to evaluate its effect on the anti-tumor activity of the CTLs against multiple myeloma (MM). Results show that PD-1 KO CTLs facilitate apoptosis and caspase activation of the co-cultured MM cells and enhanced MM cell death by 36% compared with the control.

Surgical resection and liver transplantation are the primary methods of treatment for HCC patients, but can only be applied to 15% of patients.

Methods: Primary gastric cancer cells prepared by short-term culture were used as targets. ATLs-mDCs were subjected to activate autologous T cells to generate CTLs.

Aim: To explore the efficiency of antitumor immunity induced by autologous dendritic cells (DCs) transfected with total RNA of autologous gastric cancer cells.
Methods: Short-term cultured primary gastric cancer cells were prepared. DCs in peripheral blood mononuclear cells (PBMCs) from gastric cancer patients were induced with rhGM-CSF, rhIL-4 and TNF-alpha.
