  • Hypotheses of Potential Mechanisms of Cancer Stem Cell in Peritoneal Metastasis of Gastric Cancer

    ObjectiveTo explore and hypothesize the potential mechanisms of cancer stem cell(CSC) in peritoneal metastasis of gastric cancer. MethodsThe databases of PubMed and CNKI were searched, and relevant literatures were reviewed to draw out systematic hypotheses. ResultsMetastatic cancer stem cell(MCSC) was the subpopulation of CSC with the capacity of metastasis, had still not been well investigated. MCSC transfer was the tendency of migration and planting to specific target tissue by multi-steps of "homing" process. Peritoneal metastasis of gastric cancer was a simplified "homing" process, and we thinked that the key steps were adhesion, migration, and niche establishment of MCSC in peritoneum. That capturing human MCSC of peritoneal metastases in gastric cancer and identifying its stemness feature to determine high tumorigenicity and high invasive ability of it were the important research fields. ConclusionMCSC might play certain role in multiple processes in peritoneal metastasis of gastric cancer, but currently it's lack of relevant researches.

  • Learning Curve of Allogeneic Mouse Model of Peritoneal Heart Transplantation

    Allogeneic mouse model of peritoneal heart transplant is a microscopic surgery on small animal with complex techniques. For a beginner, a learning curve of this surgical technique has to be experienced. The learning curve contains three stages:(1) to be familiar with the local anatomy of either donor or recipient mouse; (2) to be capable of collecting donor heart and well preparing the major peritoneal vessels of recipient; (3) to be skillful in the anastomosis of major vessels. The bottleneck of the learning curve is the valid skill of vascular anastomosis. The stepwise essentials are to "understand, be familiar, be accurate, and be quick" in the learning curve.

  • Enlightenment and Development of Clinical Research Ability of Preclinical Medical Students: An Exploration to Research Volunteer Mode

    Modern medicine is being transferring from traditional "empirical medicine" to more scientific "evidence-based medicine", which embodies the idea that clinical research is a primary motive that keeps medical practice continuously developing. Therefore, the contemporary aim of medical education should focus on attaching great importance to and strengthen the training of medical students' clinical scientific research ability. Based on clinical departments, we have built an open research project platform for volunteers for medical students before engaging in medical practice. Through a spirally-progressing teaching mode of "Training-Practice-Assessment-Retraining" for medical students before engaging in medical practice, the platform provides training on the knowledge and skills of evidence-based medicine and clinical scientific research. Through the volunteers' active and omnibearing practice, this project achieves some good outcomes in teaching and learning experience. This extracurricular teaching mode provides a platform for scientific research volunteers with the capacity for more knowledge before engaging in medical practice, which is recommended to empower the students with ability of scientific research.
