Interaction in classroom teaching is a bilateral activity that is difficult to control. Teachers and students are the two main aspects to realize the synchronization of teachers and students' thinking. For teachers, teachers should first make full use of multimedia resources, bring a colorful courseware into class-room teaching; secondly, teachers should stimulate students' interest in a reasonable way, so as to inject vitality into the classroom teaching; finally, teachers should mobilize the students' thinking and carefully regulate the changes in thinking between teachers and students through a proper teaching methods. In terms of students, students should not only give full play to their initiative, but also actively cooperate with teachers in order to realize the thought synchronization between teachers and students in classroom teaching and learning interaction and ultimately achieve the desired results.

AIM: To identify the human leucocyte antigen A2 (HLA-A2) restricted cytotoxic T lymphocyte (CTL) epitopes from tumor antigen PIWIL2.METHODS:RT-PCR and Western blot was used to determine the expres-sion of PIWIL2 in cancer cell lines MCF-7, SW480 and HT-29.HLA-A2 epitopes from PIWIL2 protein were predicted by the software of BIMAS, RankPep, NetMHC, NetCTL1.2 and IEDB.The peptides were synthesized by standard solid-phase methods.The binding affinity of the peptides to HLA-A2 molecules was evaluated by T2 cells binding assay.ELISPOT as-say was used to investigate the levels of IFN-γ.The cytotoxicity assay in vitro was also used to determine the ability of indu-cing T cell response by the peptides.RESULTS:The expression of PIWIL2 was observed in MCF-7, SW480 and HT-29. The candidate peptide P485, P493 and P965 showed moderate affinity toward HLA-A2 molecule.ELISPOT assay showed P485 and P965 induced CTLs of IFN-γrelease form CTLs.The CTLs induced by P485 and P965 lysed the MCF-7 cells. CONCLUSION:The peptides P485 and P965 are excellent HLA-A2 restricted cytotoxic T lymphocyte epitopes from the tumor antigen PIWIL2, which could serve as new candidates towards antitumor peptide vaccines.

The challenging clinical outcomes associated with advanced cervical cancer underscore the need for a novel therapeutic approach. Monensin, a polyether antibiotic, has recently emerged as a promising candidate with anti-cancer properties. In line with these ongoing efforts, our study presents compelling evidence of monensin's potent efficacy in cervical cancer. Monensin exerts a pronounced inhibitory impact on proliferation and anchorage-independent growth. Additionally, monensin significantly inhibited cervical cancer growth in vivo without causing any discernible toxicity in mice. Mechanism studies show that monensin's anti-cervical cancer activity can be attributed to its capacity to inhibit the Wnt/β-catenin pathway, rather than inducing oxidative stress. Monensin effectively reduces both the levels and activity of β-catenin, and we identify Akt, rather than CK1, as the key player involved in monensin-mediated Wnt/β-catenin inhibition. Rescue studies using Wnt activator and β-catenin-overexpressing cells confirmed that β-catenin inhibition is the mechanism of monensin’s action. As expected, cervical cancer cells exhibiting heightened Wnt/β-catenin activity display increased sensitivity to monensin treatment. In conclusion, our findings provide pre-clinical evidence that supports further exploration of monensin's potential for repurposing in cervical cancer therapy, particularly for patients exhibiting aberrant Wnt/β-catenin activation.

Intraoperative pleural lavage cytology is a diagnostic technique used to detect tumor cells and serve as a prognostic parameter for non-small cell lung cancer (NSCLC) patients. In the past several decades, many scholars have been dedicated to clarifying the relationships between positive intraoperative pleural lavage cytology results and postoperative survival as well as tumor recurrence and metastasis. However, the findings remained various due to the inhomogeneity of different research. It has been confirmed that a positive intraoperative pleural lavage cytology result is one of the risk factors for the prognosis of postoperative patients. This study reviewed the advances in research of intraoperative pleural lavage cytology in recent years from several aspects, including clinical significance, influencing factors and possible mechanisms.
