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.

Objective:To investigate the efficacy of vital pulp therapy versus pulp revascularization in the treatment of irreversible pulpitis and apical periodontitis in young permanent teeth. Methods:This study used a retrospective design. Fifty-six children with irreversible pulpitis and apical periodontitis in young permanent teeth, admitted to Shaoxing Stomatological Hospital from January 2022 to June 2024, were selected for the study. The children were divided into Group A ( n = 28) and Group B ( n = 28) based on treatment methods. Group A received vital pulp therapy, while Group B underwent pulp revascularization. The efficacy of both groups was compared 12 months after surgery. The root length and apical foramen size were compared between the two groups before surgery, as well as 3 and 12 months after surgery. The imaging findings were also compared between the two groups 3 and 12 months after surgery. Results:There was no significant difference in efficacy between the two groups ( P>0.05). The root lengths in Group A at 3 and 12 months after surgery were (13.17 ± 1.52) mm and (14.34 ± 1.68) mm, respectively, which were significantly greater than those in Group B [(11.86 ± 1.29) mm, (13.09 ± 1.45) mm; t = 3.48, 2.98, both P<0.05]. The apical foramen sizes in Group A at 3 and 12 months after surgery were (2.17 ± 0.32) mm and (1.61 ± 0.27) mm, respectively, and were significantly smaller than those in Group B [(2.53 ± 0.37) mm, (1.98 ± 0.31) mm; t = -7.03, -4.76, both P<0.05]. The proportion of children with an open apical foramen in Group A at 3 months after surgery was significantly lower than that in Group B [35.71% (10/28) vs. 64.29% (18/28); χ2 = 4.57, P<0.05). However, there was no statistically significant difference in the proportion of open apical foramina between the two groups at 12 months after surgery ( P>0.05). Conclusions:Vital pulp therapy shows good efficacy in the treatment of irreversible pulpitis and apical periodontitis in young permanent teeth. Compared with pulp revascularization, vital pulp therapy can remarkably reduce apical foramen size and increase root length, making it a valuable option for clinical practice.

Objective:To analyze the current status of anesthesiology research in the world and China in 2023 and to identify the anesthesiology research hotspots using bibliometrics.Methods:The literature related to anesthesiology published in PubMed in 2023 was searched, and the country and author of the literature, as well as the key words of the literature were visually analyzed by using the software CiteSpace6.2. R4.Results:A total of 22 473 articles were included, the country with the largest number of publications was the United States, and China ranked second. The author with the highest number of publications in the field of anesthesiology in the worldwide in 2023 was Kaye Alan D from the United States. Chronic pain, general anesthesia and pain management were the research hotspots in the field of anesthesiology worldwide in 2023. The research hotspots in the field of anesthesiology in China focused on general anesthesia, oxidative stress and neuropathic pain.Conclusions:The United States is the leader in the research in the field of anesthesiology, with China following behind. The keywords of the literature in the field of anesthesiology between China and the world are roughly the same, reflecting the convergence of Chinese scientific research with global scientific research. Domestic anaesthesia practitioners can refer to or learn from the research hotspots of related countries and strengthen communication and cooperation between teams while conducting academic research.

Epigenomic imbalance drives abnormal transcriptional processes,promoting the onset and progression of cancer.Although defective gene regulation generally affects carcinogenesis and tumor suppression networks,tumor immunogenicity and immune cells involved in antitumor responses may also be affected by epigenomic changes,which may have significant implications for the development and application of epigenetic therapy,cancer immunotherapy,and their combinations.Herein,we focus on the impact of epigenetic regulation on tumor immune cell function and the role of key abnormal epigenetic processes,DNA methylation,histone post-translational modification,and chromatin structure in tumor immunogenicity,and introduce these epigenetic research methods.We emphasize the value of small-molecule inhibitors of epigenetic modulators in enhancing antitumor immune responses and discuss the challenges of developing treatment plans that combine epigenetic therapy and immuno-therapy through the complex interaction between cancer epigenetics and cancer immunology.

Objective To explore the effect of pregabalin on sleep of patients after video-assisted thoracic surgery(VATS).Methods 120 cases of patients undergoing VATS under general anesthesia were randomly divided into 75 mg pregabalin group(group A),150 mg pregabalin group(group B),and placebo group(group C),with 40 patients in each group.On the night of the operation,the morning and evening of the first day and the second day after the operation,the patients in the three groups were given one tablet of pregabalin(75 mg),one tablet of placebo with the same shape and smell,two tablets of pregabalin(150 mg)and two tablets of placebo with the same shape and smell respectively.Athens insomnia scale(AIS)was used to evaluate the incidence of postoperative sleep disturbance(PSD)on the night of operation,and the patients'sleep quality every night from one night before operation to the 2nd day after operation was assessed using the St.Mary's Hospital sleep questionaire(SMH).Pittsburgh sleep quality index(PSQI)was used to evaluate the patients'sleep quality one day before the operation,7 days after operation,and 1 month after the operation.The digital rating scale(NRS)was used to evaluate the patients'pain at the incision and the surgical side.The remedial analgesia,incidence of adverse events in the 72 h postoperative period,and patient satisfaction score were recorded.Results The incidence of PSD in group A,group B and group C was 45.0％,42.5％and 72.5％,respectively,the incidence of group A and group B was significantly lower than in group C(group A,B and C compared in pairs,P＜0.016 7).The SMH scores in group A and group B were significantly higher than in group C on the day of operation,the first day and the second day after operation(group A,B and C compared in pairs,P＜0.016 7).The incidence of NRS scores in groups A and B at the incision and postoperative remedial analgesia was significantly lower than in group C on postoperative day 1 and postoperative day 2(group A,B and C compared in pairs,P＜0.016 7).There was no statistically significant difference in the pain scores at the incision and shoulder among the three groups at the remaining time points.The postoperative patient satisfaction scores were significantly higher in group A and group B than in group C(P＜0.01).The incidence of dizziness in group B was significantly higher than in the other two groups(P＜0.016 7).Conclusion Oral administration of pregabalin(75 mg/150 mg)for 3 days after VATS can reduce the incidence of PSD and improve the quality of sleep that night,but oral administration of 150 mg pregabalin may increase the incidence of dizziness.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.
