As a safety culture placed between a culture of punishment and that of exemption, just culture can effectively improve the reporting rate of medical adverse events, promote medical staff to learn from events, and continuously improve patient safety management. The authors searched for literature on the study of just culture in medical institutions both domestically and internationally, including such databases as CNKI, Wanfang Data, and PubMed from 2001 to January 2023. They reviewed the concept of just culture and its connotation in the field of patient safety management, as well as the current research status of just culture in medical institutions both domestically and internationally. On such basis, they proposed for the construction of just culture in medical institutions in China, for reference in the construction and evaluation of a just culture in such institutions.

Objective To evaluate the clinical outcomes of hemodialysis patients after superficial femoral artery - superficial femoral vein arteriovenous graft (AVG). Methods Hemodialysis patients with mid - thigh superficial femoral artery - superficial femoral vein AVG from August 2015 to March 2018 in department of vascular surgery, Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine were enrolled. Their clinical outcomes and complications after operation were analyzed retrospectively. Patency rates were measured by Kaplan - Meier survival curve. Results A total of 18 cases were enrolled. The success rate of the operation was 100％without complication. Follow - up time was (22.00 ± 11.77) months with 100％ follow - up rate. The 6 months -, 12 months -, 24 months - primary patency rates were 83.3％±8.8％, 48.5％±12.1％, 24.2％± 13.5％, respectively; secondly patency rates were 100.0％, 100.0％, 87.5％±11.7％. There were 1 case of seroma, 1 case of puncture site infection, 11 cases of stenosis and 5 cases thrombosis during follow-up, while no heart failure, ischemia or pseudoaneurysm. Conclusion Mid - thigh AVG has low infection rate and high patency rate, so it can be as the first choice for the lower extremity AVG in hemodialysis patients.

Primary bile acids were reported to augment secretion of chemokine (C‒X‒C motif) ligand 16 (CXCL16) from liver sinusoidal endothelial cells (LSECs) and trigger natural killer T (NKT) cell-based immunotherapy for liver cancer. However, abundant expression of receptors for primary bile acids across the gastrointestinal tract overwhelms the possibility of using agonists against these receptors for liver cancer control. Taking advantage of the intrinsic property of LSECs in capturing circulating nanoparticles in the circulation, we proposed a strategy using nanoemulsion-loaded obeticholic acid (OCA), a clinically approved selective farnesoid X receptor (FXR) agonist, for precisely manipulating LSECs for triggering NKT cell-mediated liver cancer immunotherapy. The OCA-nanoemulsion (OCA-NE) was prepared
