Objective To explore the application of transesophageal echocardiography (TEE) probe insertion under video laryngoscopy in acute severe patients. Methods Sixty acute severe patients, ASA grade II-IV, underwent non-cardiac surgery under general anesthesia were divided into two groups (A and B) evenly by random number method.TEE probe was blindly inserted into the group A patients, and in group B, a video laryngoscope was used to assist the insertion.The first insertion success rate, the time required for insertion, the changes of hemodynamics during insertion, and the adverse reactions incidence during insertion of the two groups were compared. Results The first insertion success rate of the group B (82.8%) was significantly higher than that of the group A (58.6%), the difference was statistically significant (P<0.05). The time required for the first successful insertion of the group B was significantly longer than that of the group A, (24.6±3.1) s vs (15.5±3.0) s, and the difference was statistically significant (P<0.05). The total time required to insert the probe was not significantly different between the two groups (P> 0.05). Throat injury in the group B was significantly less than that in the group A (3.4% vs 27.6%), the difference was statistically significant (P<0.05). The hemodynamics (MAP and HR) of the two groups during insertion were not significantly different (P>0.05).

Objective To explore the application and follow-up monitoring and diagnostic value of lung ultrasound (LUS) in elderly patients(≥75y) with novel coronavirus pneumonia (COVID-19). Methods Data of 25 COVID-19 elderly patients admitted to the Department of Internal Medicine from November 1, 2022 to January 15, 2023 were retrospectively analyzed and summarized. In addition to clinical data, dynamic monitoring of LUS was performed, and the results were compared with lung CT results. The examination results, as well as the prediction and impact on the course of disease were observed. Results LUS imaging indicated that patients had different degrees of interstitial lung injury, including discrete type B line (interstitial exudation) or fusion type B line (alveolar infiltration) and lung consolidation (alveolar collapse). With the improvement of the disease, the range of lung consolidation seen in LUS was reduced, the B-line was gradually sparse to dissipate, and the A-line appeared. Conclusions The results of LUS and chest CT in the same period are consistent. LUS examination is safe, simple, reproducible, and can be monitored dynamically in real time. It can be used as a primary screening method, and also be used in special patients to assist clinical treatment decision-making.

非酒精性脂肪性肝病(NAFLD)是世界范围内慢性肝病的一个主要原因,约15%的NAFLD患者会发展为非酒精性脂肪性肝炎、肝纤维化、肝硬化甚至肝癌。目前其发病及进展机制尚未明确,也无有效治疗手段。因此,构建临床前NAFLD动物模型至关重要,有助于为NAFLD提供临床治疗的新方案。本文将系统分析目前已构建的NAFLD动物模型在临床前研究中的局限性,并重点总结和综述基于基因编辑在NAFLD动物模型构建中的应用及研究进展,这对于探讨NAFLD发病机制及新药研发具有重要的临床意义。

Nonalcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease worldwide, and about 15% of NAFLD patients will develop into nonalcoholic steatohepatitis, hepatic fibrosis, cirrhosis, and ultimately hepatocellular carcinoma. However, the biological mechanism of the pathogenesis and progression of NAFLD is not fully understood, and there are still no effective or targeted therapies for NAFLD. Therefore, it is an urgent need to construct pre-clinical animal models of NAFLD, which will help to better understand and explore the potential therapeutic strategy in the treatment of NAFLD. Here, we summarize the recent advances and limitations of the established animal models of NAFLD and focus on the potential application and research progress of genome editing for constructing the animal models of NAFLD. There animal models will be very useful to reveal the pathologic mechanism of human NAFLD, and to screen new therapeutic drugs.
