Objective:To analyze the research trends and hotspots of bupivacaine liposomes from 1994 to 2023 using bibliometrics.Methods:A comprehensive search was conducted for the literature related to bupivacaine liposomes in the Web of Science Core Collection from 1994 to 2023. The CiteSpace software was used to conduct an in-depth analysis of the included literature data, including publication year, country, institution, author, journal, cited references, keywords, etc.Results:A total of 875 papers related to bupivacaine liposomes were included. The research and development of bupivacaine liposomes were divided into 3 stages: slow development (1994-2011), a sharp rise (2011-2021), and stabilization (2021-2023). The United States was in a leading position in terms of the number of publications, centrality, and author cooperation, and Harvard University had the largest number of publications. de Paula E had the most publications, Bramlett K had the highest number of citations, and Boogaerts J had the highest centrality of publications. Journals such as Anesthesia and Analgesia made significant contributions to this field. The most cited references focused on the infiltration of wounds and the periprosthetic injection of bupivacaine liposomes. The keyword analysis showed that local anesthetics, postoperative pain, etc. were commonly used keywords, and enhanced recovery after surgery was an emerging hotspot. Conclusions:Bupivacaine liposomes show good application prospects in the field of peripheral nerve block due to their unique pharmacological properties and safety characteristics and are expected to prolong the duration of postoperative analgesia. However, there is a difference between the actual effect and the expectation, and more clinical trials are needed to evaluate the curative effect, providing a more solid and reliable theoretical basis and practical guidance for clinical practice.

Nonalcoholic fatty liver disease (NAFLD) is characterized by hepatic steatosis and insulin resistance and there are currently no approved drugs for its treatment. Hyperactivation of mTOR complex 1 (mTORC1) and subsequent impairment of the transcription factor EB (TFEB)-mediated autophagy-lysosomal pathway (ALP) are implicated in the development of NAFLD. Accordingly, agents that augment hepatic TFEB transcriptional activity may have therapeutic potential against NAFLD. The objective of this study was to investigate the effects of nuciferine, a major active component from lotus leaf, on NAFLD and its underlying mechanism of action. Here we show that nuciferine activated ALP and alleviated steatosis, insulin resistance in the livers of NAFLD mice and palmitic acid-challenged hepatocytes in a TFEB-dependent manner. Mechanistic investigation revealed that nuciferine interacts with the Ragulator subunit hepatitis B X-interacting protein and impairs the interaction of the Ragulator complex with Rag GTPases, thereby suppressing lysosomal localization and activity of mTORC1, which activates TFEB-mediated ALP and further ameliorates hepatic steatosis and insulin resistance. Our present results indicate that nuciferine may be a potential agent for treating NAFLD and that regulation of the mTORC1-TFEB-ALP axis could represent a novel pharmacological strategy to combat NAFLD.

In recent years, the medical insurance coverage of China has been increased significantly, and the medical insurance policies have been launched continuously, so the traditional manual audit method is unable to support medical institutions to effectively supervise the medical insurance fund. In view of this situation, a tertiary hospital in Beijing had successfully built an intelligent medical insurance audit system for drugs, diagnosis and treatment projects under key supervision, realized the prior audit and in-process control of the illegal use of medical insurance funds, through the establishment of intelligent audit rules, the design of audit trigger points and the interception level of illegal medical orders, and the establishment of a pre-operational preparation system and continuous improvement mechanism. In March 2021, the hospital officially launched the system. After the application of the system, the amount and quantity of outpatient medical insurance refusal from April to September 2021 were 10 587 yuan and 72 respectively, which decreased by 79.21% and 77.50% compared with the same period in 2020. This system effectively improved the quality and efficiency of medical insurance fund supervision.

OBJECTIVE: To summarize and analyze the clinical characteristics of Mondini dysplasia with cerebrospinal fluid leakage, as well as preliminarily investigate the genetic mechanism of the disease. METHOD: The clinical data of 2 patients diagnosed as Mondini dysplasia with cerebrospinal fluid leakage treated in our hospital were analyzed. Blood samples of these two patients were obtained to extract DNA. We screened DNA samples for gene SLC26A4 mutations by using polymerase chain reaction and direct sequencing. The sequencing results were analyzed in DNASTAR software. RESULT: Both patients came to our hospital because of recurrent meningitis, and the fistula were both located in vestibular window. Patients were cured one-time after surgical closure of the leakages with temporalis + temporalis fascia + temporalis through the mastoid approach. No pathogenic mutations of gene SLC26A4 with exome sequencing were found. CONCLUSION Mondini dysplasia with cerebrospinal fluid leakage should be considered in patients with recurrent meningitis and hearing disorder. Temporal bone HRCT is helpful to the diagnosis. Surgical closure is an effective therapeutic method and may prevent recurrent meningitis. The molecular mechanism of simple Mondini dysplasia needs further study.
