Objective:To conduct a bibliometric analysis of perioperative hypothermia related research,and to reveal the research status,hot research and frontier development in this field.Methods:The core journal literatures on perioperative hypothermia included in CNKI and Web of Science from 2004 to 2023 were systematically searched,and CiteSpace 6.2.R3 software was used for visual analysis.Results:A total of 224 Chinese articles and 883 English articles were included,and the number of articles published showed an overall upward trend.The research hotspots included colorectal surgery,elderly patients,surgical site infection,active heating,etc.The development trends include cancer care,predictive models,artificial intelligence,etc.Conclusion:In recent years,the research on perioperative hypothermia has shown an increasing trend,which is the focus of attention of scholars at home and abroad.China's number of publications is second only to the United States,but its external collaboration and academic influence are weak.In the future,the artificial intelligence technology should be used to implement scientific and effective evidence-based nursing,carry out early warning intervention for key populations of perioperative hypothermia,and broaden the depth and breadth of perioperative hypothermia research,so as to enhance China's academic influence.

Objective:To investigate the status quo of the whole process nursing needs of patients with gastrointestinal tumor surgery based on Kano model, and to provide a theoretical reference for the development of high quality nursing service.Methods:From August to September 2023, a cross-sectional survey was conducted on 284 patients undergoing gastrointestinal tumor surgery in Renji Hospital Affiliated to Shanghai Jiao Tong University by simple sampling method. Based on the Kano model as the theoretical framework, referring to the relevant literature, the questionnaire of the whole process nursing needs of patients with gastrointestinal tumor surgery was determined by two rounds of Delphi method, and the 'maximum frequency method' was used to classify the attributes of the whole process nursing needs of patients with gastrointestinal tumor surgery.Results:A total of 270 valid questionnaires were retrieved. Among 270 patients, 159 were males and 111 were females, aged 22-94 (65.34 ± 8.77) years. Among the 26 items, 16 nursing needs were expected attributes, and the first two nursing needs were pain care and relieving oral dryness. 7 essential attributes, the top 2 were relieving insomnia / drowsiness and preoperative preparation and nursing; 2 charm attributes, for postoperative follow-up and follow-up process nursing; 1 indifference attribute, which was the introduction of the surgical environment. The results of quadrant analysis showed that there were 46.15%(12/26) demands in the first quadrant (dominant area), 23.08%(6/26) in the third quadrant (observation area), and both 15.38%(4/26) in each of the other two quadrants.Conclusions:The whole process nursing needs of patients with gastrointestinal tumor surgery are diversified, and the hospital should actively meet the expected attributes and essentials of patients. On this basis, it should provide and innovate charm attribute services to improve patient satisfaction and improve the core competitiveness of the hospital.

Objective:To explore the current status and research hotspots of structural equation modeling in nursing from 2012 to 2021.Methods:We searched for literature on the structural equation modeling in nursing based on Web of Science core collection database. CiteSpace and Excel were used to analyze the time, space, and keywords included in 742 articles.Results:From 2012 to 2021, the number of domestic and international publications showed a rapid growth trend with the growth of the year. China was the country with the highest number of publications. The Western University in Canada was the institution with the highest number of publications. The frequency of keywords such as structural equation modeling, quality of life, job satisfaction, health, social support and stress was high. The clustering effect of keywords was significant ( Q=0.72, S=0.87) , and research hotspots mainly included physical and mental health care and nursing work management. Conclusions:The structural equation modeling in nursing is showing a rapid development trend. In the future, numerous studies should be conducted on the construction and validation of nursing structural relationship models to promote the development of nursing.

Background:Acute lung injury(ALI)is the most common organ dysfunction in severe acute pancreatitis(SAP).Somatostatin analogue octreotide is a common used drug in acute pancreatitis.Aims:To explore the protective mechanism of octreotide on lung injury in SAP mice.Methods:In the first part,the experimental mice were randomly assigned into four groups.SAP model was induced by caerulin and lipopolysaccharide,and the mice were sacrificed 24 hours,48 hours and 72 hours after establishment.HE staining was used to observe the pathological score of pancreas and lung.Serum amylase and lung tissue myeloperoxidase(MPO)activity were detected.Real-time quantitative PCR was used to detect mRNA expressions of pyroptosis-related molecules apoptosis-associated speck-like protein containing a CARD(ASC),caspase-1,Gasdermin D(GSDMD),interleukin(IL)-1β,IL-18 and inflammatory factors IL-6,tumor necrosis factor(TNF)-α,high mobility group protein B1(HMGB1)in lung tissue.Western blotting was used to detect protein expressions of NOD-like receptor thermal protein domain associated protein 3(NLRP3),caspase-1,GSDMD and IL-1β in lung tissue.In the second part,mice were randomly divided into control group,SAP group,and octreotide group.HE staining was used to observe the pathological score of pancreas and lung.Serum amylase and lung tissue MPO activity were detected.Real-time quantitative PCR was used to detect mRNA expressions of pyroptosis-related molecules caspase-1,ASC,IL-1β,IL-18 and inflammatory factors IL-6,TNF-α,HMGB1.Immunofluorescence was used to detect protein expressions of NLRP3,caspase-1,GSDMD,ASC,IL-1β in lung tissue.Results:In the first part,compared with control group,pathological score of pancreas and lung tissue,serum amylase and MPO activity were significantly increased in SAP group(all P<0.05),mRNA expressions of pyroptosis-related molecules caspase-1,ASC,GSDMD,IL-1β,IL-18 and inflammatory factors IL-6,TNF-α,HMGB1 were significantly increased(all P<0.05),protein expressions of NLRP3,caspase-1,GSDMD and IL-1β in lung tissue were significantly increased(all P<0.05),especially in 24 hours after establishment group.In the second part,compared with SAP group,pathological score of pancreas and lung tissue,serum amylase were significantly decreased in octreotide group(all P<0.05),mRNA expressions of pyroptosis-related molecules caspase-1,ASC,IL-1β,IL-18 and inflammatory factors IL-6,TNF-α,HMGB1 were significantly decreased in lung tissue in octreotide group(all P<0.05),protein expressions of NLRP3,caspase-1,GSDMD,ASC and IL-1β in lung tissue were significantly decreased(all P<0.05).Conclusions:Cell pyroptosis is involved in the occurrence and development of lung injury in SAP mice,and octreotide may attenuate lung injury in SAP mice by inhibiting pyroptosis.
