Improved split prime editors enable efficient in vivo genome editing.

Efficient prime editor (PE) delivery in vivo is critical for realizing its full potential in disease modeling and therapeutic correction. Although PE has been divided into two halves and delivered using dual adeno-associated viruses (AAVs), the editing efficiency at different gene loci varies among split sites. Furthermore, efficient split sites within Cas9 nickase (Cas9n) are limited.

Needlescopic Laparoscope Sleeve Gastrectomy (NLSG): a Potential Surgical Approach.

Background: Laparoscopic sleeve gastrectomy has become the most popular weight loss surgery currently, but it inevitably leaves multiple small scars in the abdomen. Although the appearance of single-incision laparoscopic sleeve gastrectomy achieve better cosmetic results, it may lead to postoperative complications such as umbilical hernia and umbilical infection. The author has developed a new surgical approach that can compensate for these deficiencies, which we called needlescopic laparoscope sleeve gastrectomy (NLSG).

A new method to predict hospital mortality in severe community acquired pneumonia.

Background & Aims: The aim of this study is to develop a new method that is able to accurately predict the 28day hospital mortality in patients with severe community acquired pneumonia (SCAP) at an early stage.

Methods: We selected 37,348 SCAP patients in ICU from 173 hospitals during 2011.1-2013.
