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 analyze the epidemiological distribution of new occupational pneumoconiosis (hereinafter referred to as "pneumoconiosis") in Guangxi Zhuang Autonomous Region from 2013 to 2022. Methods Data of newly diagnosed pneumoconiosis cases reported in Guangxi Zhuang Autonomous Region from 2013 to 2022 were collected, and epidemiological characteristics were analyzed using descriptive analysis method. Results A total of 972 newly diagnosed pneumoconiosis cases were reported in Guangxi Zhuang Autonomous Region from 2013 to 2022. Except for mica pneumoconiosis, 12 other types of pneumoconiosis were reported. Most of the cases were males, accounting for 97.0%. The diagnosis age of the cases of 40-<60 years old accounted for 77.4%, and the dust exposure age<30 years of the cases accounted for 96.4%. Silicosis was the most common type of pneumoconiosis, followed by coal workers' pneumoconiosis, accounting for 64.6% and 27.9%, respectively. The cases of stage Ⅰ, Ⅱ and Ⅲ pneumoconiosis accounted for 77.7%, 14.9% and 7.4%, respectively. The regional distribution was mostly in Hechi City, accounting for 51.9%. Industry distribution was more common in non-ferrous metal mining, coal mining and washing industry, accounting for 64.9% in total. Most cases were reported in private enterprises and small to medium-sized enterprises, accounting for 53.7% and 76.6% respectively. The most common occupations were coal miners and drillers, accounting for 47.7% in total. Conclusion Newly diagnosed pneumoconiosis cases in Guangxi Zhuang Autonomous Region show certain clustering characteristics in terms of disease type, region, enterprise characteristics, and occupation distribution. The prevention and treatment of pneumoconiosis in small and medium-sized private enterprises in key areas and key industries should be strengthened, especially for workers over 40 years old and with less than 30 years of dust exposure.

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
