We briefly share our experience of using the silent mentor program in the Medical Simulation Center (MSC) of Tzu Chi University (TCU), Hualien, Taiwan, to improve our minimally invasive surgical level and patient's safety. The silent mentor program, established in 2000 by the Department of Anatomy of TCU, is a pioneering clinical skill training program based on unembalmed bodies. This program provides three valuable advantages for surgery. The first is the comprehensive understanding of the deep or rarely observed but crucial structures of the human body, which is normally difficult to achieve in living humans. The second is gaining the first experience of a novel procedure or surgery on silent mentors rather than on living humans, which is essential for young surgeons to begin their careers. The third is evaluating the safety and feasibility of a novel surgical method. In addition to surgical techniques, the most valuable point of the program is the humane ceremonies conducted for silent mentors to nourish our soul. After the workshop, all the incision wounds on every silent mentor were carefully checked and sutured in the same manner as in closing surgical wounds in a patient. Subsequently, encoffining, cremation, and thanksgiving ceremonies were solemnly held, in the hope that the medical students or trainees would imperceptibly understand their responsibility to society and the silent mentor's expectations. The Asia-Pacific Association for Gynecologic Endoscopy and Minimally Invasive Therapy, or the Taiwan Association for Minimally Gynecology Therapy, or both can consider initiating a regular silent mentor program in the MSC of TCU. It is not only intended to improve the skills of surgeons but also to allow them to participate in the interactive ceremony and thus refresh their humanitarian knowledge.

Exosomes are phospholipid bilayer vesicles that are released by all types of cells, containing proteins, lipids, and nucleic acids such as DNAs and RNAs. Exosomes can be transferred between cells and play a variety of physiological and pathological regulatory functions. Noncoding RNAs, including micro RNAs, long noncoding RNAs, and circular RNAs, are the most studied biomolecules from exosomes and more and more studies found that noncoding RNAs play an important role in the diagnosis, prognosis, and treatment of diseases, including various types of cancer. Gynecological malignancies such as ovarian, endometrial, and cervical cancer seriously threaten women’s life. Therefore, this article reviews the roles and applications of exosomes in gynecological malignancies, including the promotion or inhibition of tumor progression and regulation of tumor microenvironments, and as potential therapeutic targets for treating gynecological cancers.

Fallopian tube epithelial cells (FTEC) are thought to be the cell of origin of high-grade serous ovarian carcinoma. FTEC organoids can be used as research models for the disease. Nevertheless, culturing organoids requires a medium supplemented with several expensive growth factors. We proposed that a combined conditioned medium based on the composition of the fallopian tubes, including epithelial, stromal, and endothelial cells could enhance FTEC organoid formation. We derived two primary culture cell lines from the fimbria portion of the fallopian tubes. The organoids were split into conventional or combined medium groups based on what medium they were grown in and compared. The number and size of the organoids were evaluated. Quantitative polymerase chain reaction (qPCR) and immunohistochemistry (IHC) were used to evaluate gene and protein expression (PAX8, FOXJ1, beta-catenin, and stemness genes). Enzyme-linked immunosorbent assay was used to measure Wnt3a and RSPO1 in both mediums. DKK1 and LiCl were added to the mediums to evaluate their influence on beta-catenin signaling. The growth factor in the combined medium was evaluated by the growth factor array. We found that the conventional medium was better for organoids regarding proliferation (number and size). In addition, WNT3A and RSPO1 concentrations were too low in the combined medium and needed to be added making the cost equivalent to the conventional medium. However, the organoid formation rate was 100% in both groups. Furthermore, the combined medium group had higher PAX8 and stemness gene expression (OLFM4, SSEA4, LGR5, B3GALT5) when compared with the conventional medium group. Wnt signaling was evident in the organoids grown in the conventional medium but not in the combined medium. PLGF, IGFBP6, VEGF, bFGF, and SCFR were found to be enriched in the combined medium. In conclusion, the combined medium could successfully culture organoids and enhance PAX8 and stemness gene expression. However, the conventional medium was a better medium for organoid proliferation. The expense of both mediums was comparable. The benefit of using a combined medium requires further exploration.
