The plant growth process is accompanied by dynamic changes in the microtubules, and the rearrangement of microtubules is regulated by diverse microtubule-associated proteins(MAPs). Plant MAP65s have been exhaustively characterized in some species, but the information about MAP65 family members in tomato(Solanum lycopersicum) is limited. In this study, nine SlMAP65 family genes were identified in the tomato genome. Then a systematic analysis that considered the physio-chemical properties, evolution, conserved motifs, domains, gene structure, and cis-regulatory elements of SlMAP65 family members was conducted. The family member Sl MAP65-1,which had the highest expression, was knocked out by CRISPR/Cas9. The tomato fruit of slmap65-1 loss of function lines showed an elongated morphology, and the data indicated that SlMAP65-1 is involved in fruit morphogenesis at the early fruit development stage. These results provide new insights for fruit morphogenesis-related research and future functional studies of the SlMAP65 family members in tomato.

Liver transplantation is hindered by organ shortage. The potential way to relieve this issue is to expand the donor pool via extending the donor criteria and make full use of all available grafts. The concept of “no-donor” liver transplantation allows grafts to be recovered from other liver recipients. This review summarizes the current clinical practice of “no-donor” liver transplantation, focusing on the experiences of Chinese transplant teams. Domino liver transplantation was introduced by Furtado in 1995 and implemented later in 2013 in China, and novel donor indications including some essential-to-treat inherited metabolic liver-based diseases have emerged. The concept of cross-auxiliary domino liver transplantation brings a further expansion of the domino liver graft pool, and the first pair of liver transplantation performed “rigorously without donation” was accomplished in our center in 2018. Our experience with this original transplantation procedure is hereby reviewed. In order to further promote and make successful “no-donor” liver transplantation, close co-operation between researchers, surgeons, physicians, organ procurement organizations, as well as ethical committees is required.

Despite efforts to develop treatment technology for cardiac arrest (CA),CA incidence and mortality rates are still high.^([1,2])A recent study of CA patients in emergency departments revealed that the incidence of CA is increasing annually,and the in-hospital survival rate of CA patients is only approximately 28.7%.^([3])Echocardiography has been widely used as an important monitoring tool in critical care and helps to identify the cause of shock,monitor hemodynamics,and guide fluid therapy utilization.^([4])One study reported that approximately one-third of patients underwent formal echocardiography during hospitalization in the intensive care unit (ICU).
