Benmelstobart plus anlotinib in patients with EGFR-positive advanced NSCLC after failure of EGFR TKIs therapy: a phase I/II study.

The effect of immune-based therapies on patients with epidermal growth factor receptor (EGFR)-positive advanced non-small cell lung cancer (NSCLC) resistant to EGFR tyrosine kinase inhibitor (TKI) therapy remains unclear. The ALTER-L038 study aimed to evaluate efficacy and safety of a chemotherapy-free combination of benmelstobart, an anti-programmed cell death ligand 1 antibody, and anlotinib, a small-molecule multi-target anti-angiogenic TKI, in EGFR-positive advanced NSCLC patients who progressed after EGFR TKI therapy. Patients were enrolled in a phase I/II study.

Formation Mechanism of Microbial Diversity in Artificial Intelligence Devices due to Intermediate Disturbance by Low-Dose UV Radiation for Complementary Medicine.

The development of artificial intelligence devices in the complementary medicine field is rapid and the surface microbial diversity pollution was found with periodic low-dose ultraviolet radiation (LDUVR). Since artificial intelligence devices do not have enough different types of substrates for microbial communities, it is unclear how the great microbial diversity can emerge and persist, as this clearly defies the competitive exclusion principle of ecology. In this study, the 5 most common genera in the artificial intelligence devices, , , , and have been sampled without and with periodic LDUVR, respectively.

[Matrine alleviates N-methyl-N'-nitro-N-nitrosoguanidine (MNNG)-induced gastric mucosal damage in rats and its mechanism].

Objective To investigate the effect of matrine on gastric mucosal injury induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in rats and its mechanism. Methods A total of 75 Wister rats were randomly divided into a control group, a model group and three matrine-treated groups (100, 150 and 200 mg/kg). Except for the control group, the other groups were treated with MNNG to establish the models of gastric mucosal injury in the rats.

Expression and clinical significance of autophagic protein LC3B and EMT markers in gastric cancer.

Background And Aim: Gastric cancer (GC) is a fatal malignancy with high rate of recurrence and metastasis. Here, we investigated the correlations between the expression of autophagic protein LC3B and 2 epithelial-mesenchymal transition-related proteins (E-cadherin and Vimentin) and the clinicopathological factors and prognosis of patients with GC.

Materials And Methods: The expression of LC3B, E-cadherin, and Vimentin in GC samples (110 cases) and paracarcinoma tissues (40 cases) was analyzed using the Oncomine databases and further detected by immunohistochemistry.
