The International Society for Stem Cell Research has updated its Guidelines for Stem Cell Research and Clinical Translation in order to address advances in stem cell science and other relevant fields, together with the associated ethical, social, and policy issues that have arisen since the last update in 2016. While growing to encompass the evolving science, clinical applications of stem cells, and the increasingly complex implications of stem cell research for society, the basic principles underlying the Guidelines remain unchanged, and they will continue to serve as the standard for the field and as a resource for scientists, regulators, funders, physicians,

Patients in Far-Eastern countries gave various responses regarding end-of-life care decisions. Although familial input is still influential, most patients think of themselves as the major decision maker and accept the necessity of advance directives with Westernization of the society. Artificial ventilation withdrawal and even active euthanasia may be acceptable to them.

This article documents the results of a study on the perceptions of long-term elder care in Beijing in the People's Republic of China by those most intimately involved. The study asked a sample of elderly, family members, and health care professionals, all of whom are involved in care at a variety of long-term care facilities in Beijing, about their perceptions of the care given at these facilities from their particular standpoints as regards issues such as the quality and ideal location of care, decision-making regarding the care receiving, who should be responsible for the financing of care, and the meaning of dignity for the elderly in these facilities. The results showed adherence to traditional family values at least on one level regarding the ideal location of care being with the family and in the home, but also the desire to pass on financing of long-term care facilities and the health care they provide the elderly on to the government. These results are not altogether surprising, but they also clearly demonstrate the larger conflict between traditional views about morality and economic considerations regarding health care financing in the China.

Melanoma is a kind of tumor that originates from melanocytes and is characterized by chemoresistance and distant metastasis. Although the complete pathogenesis of melanoma remains unclear, increasing evidence suggests that circular RNAs (circRNAs) may be involved. In the present study, we identified a circular RNA, circ_0002770, which is produced from the well-known oncogene MDM2, and was sharply increased in melanoma and correlated with a poor prognosis. Knockdown of circ_0002770 suppressed melanoma cell invasion, migration and proliferation. Mechanistically, circ_0002770 acted as a sponge of miR-331-3p and could indirectly regulate DUSP5 and TGFBR1. Inhibition of miR-331-3p reversed the inhibitory effect of si-circ_0002770 on melanoma cell proliferation and invasion. In vivo evidence further confirmed that silencing circ_0002770 inhibited melanoma tumor formation. In conclusion, circ_0002770 facilitated melanoma cell proliferation, invasion and migration by sponging miR-331-3p and modulating DUSP5 and TGFBR1.
