The cellular and molecular components of the tumor immune microenvironment (TIME) and their information exchange processes significantly influence the trends of anti-tumor immunity. In recent years, numerous studies have begun to evaluate TIME in the context of previous cancer treatment strategies. This review will systematically summarize the compositional characteristics of TIME and, based on this foundation, explore the impact of current cancer therapies on the remodeling of TIME, aiming to provide new insights for the development of innovative immune combination therapies that can convert TIME into an anti-tumor profile.

Objective:To compare clinical features, esophageal motility, and reflux characteristics in elderly patients with gastroesophageal reflux disease(GERD)with and without extraesophageal symptoms.Methods:This study was conducted as a cross-sectional analysis involving 75 patients aged 60 years and older, who visited the outpatient department of gastroenterology at China-Japan Friendship Hospital between January and December 2023.Among these, 43 patients exhibited extraesophageal symptoms [23 males, 20 females; median age 69(66, 75)], while 32 patients did not present with such symptoms [12 males, 20 females; median age 69(66, 73.75)].We collected data regarding the patients' demographic characteristics, lifestyle habits, and comorbidities via a questionnaire, and analyzed the range of extraesophageal symptoms.The presence of reflux esophagitis was assessed according to the Los Angeles classification, and the status of the gastroesophageal valve was evaluated through gastroscopy.Additionally, we measured esophageal motility and reflux characteristics using high-resolution manometry and 24-hour pH-impedance monitoring.Results:The smoking rate was significantly higher in patients with extraesophageal symptoms compared to those without extraesophageal symptoms[39.53%(17/43) vs.15.63%(5/32), P=0.039].Conversely, the prevalence of hypertension was significantly higher in patients without extraesophageal symptoms compared to those with extraesophageal symptoms[41.86%(18/43) vs.65.63%(21/32), χ2=4.151, P=0.042].Among patients with extraesophageal symptoms, the proportion experiencing pharyngeal symptoms was the highest at 83.72% (36/43), followed by oral symptoms at 32.56%(14/43), while the lowest proportion was for respiratory symptoms at 16.28%(7/43).The esophageal body peristaltic contraction rate was significantly higher in patients without extraesophageal symptoms compared to those with extraesophageal symptoms[100%(100%, 100%) vs.100%(80%, 100%), Z=-2.671, P=0.008].The number of non-acid reflux episodes was significantly higher in patients with extraesophageal symptoms compared to those without[5.00(1.00, 5.00) vs.1.00(1.00, 2.00), Z=-3.842, P<0.001].Additionally, the proportion of proximal reflux was significantly higher in patients with extraesophageal symptoms compared to those without[83.8%(65.6%, 95.4%) vs.68.5%(59.8%, 77.35%), Z=-2.037, P=0.042]. Conclusions:Patients with GERD and extraesophageal symptoms exhibit a higher prevalence of smoking, diminished peristaltic function in the esophageal body, an increased incidence of proximal esophageal reflux, and a greater number of non-acid reflux episodes.

Objective:To analyze the hotspots and trends in thyroid cancer nursing research from 2004 to 2023 at home and abroad through bibliometric methods, so as to provide references and ideas for future research in this field.Methods:A systematic search was conducted for core journal documents on thyroid cancer nursing research included in China National Knowledge Infrastructure, Wanfang Database, VIP Chinese Journal Network and Web of Science Core Collection from January 1, 2004 to December 31, 2023, using CiteSpace6. 3.R1 software performs visual analysis.Results:A total of 119 domestic documents and 417 international documents were included for analysis. From 2004 to 2023, the number of publications in the field of thyroid cancer nursing research at home and abroad showed an upward trend. Domestic research hotspots mainly include four directions: perioperative nursing, symptom nursing, care for radioactive iodine-131 treatment, and physical and mental health promotion. Foreign research hotspots mainly include three directions: nursing practice exploration and guideline formulation, care for radioactive iodine-131 treatment, and quality of life.Conclusions:The field of thyroid cancer nursing has received continuous attention from scholars at home and abroad. In future research, it is recommended that domestic scholars actively carry out cross-institutional and multi-center team cooperation in accordance with local needs, focus on the research of physical and mental care and health promotion of thyroid cancer patients at different survival stages, and the construction of clinical nursing guidelines. With the help of core research institutions and expert teams, actively promote the development of high-quality nursing research in this field.

Osteosarcoma is a common primary malignant bone tumor in adolescents and children,characterized by a high recurrence rate and metastasis,making its treatment extremely challenging.Traditional treatment modalities,including surgery,radiation therapy,and chemotherapy,can alleviate symptoms to some extent,but improving long-term survival rates remains a pressing issue.With the continuous development of immunotherapy,breakthroughs have been made in the research of tumor immune microenvironment and the application of immunotherapy in recent years,providing new perspectives and strategies for osteosarcoma treatment.Currently,immunotherapy strategies include tumor vaccines,targeted cytokines,immune checkpoint inhibition,adoptive cell therapy,combination therapy,etc.,significantly enhancing patient immune responses from the aspects of boosting immunity,overcoming immune tolerance,and preventing immune evasion,thereby effectively improving the patients'survival rates and prognosis.This review aims to systematically introduce the immune microenvironment of osteosarcoma and discuss the latest advances in immunotherapy in clinical translational research of osteosarcoma.By deeply understanding the immune characteristics of osteosarcoma and corresponding treatment methods,it is hopeful to provide more effective strategies for personalized treatment,contributing to the improvement of the patients' survival rates and prognosis.

【Objective】 To explore the relationship between the storage time of leukodepleted red blood cells and transfusion adverse reactions by analyzing the occurrence of transfusion adverse reactions of patients after leukodepleted red blood cells transfusion from four hospitals. 【Methods】 By using the electronic medical record management system, the collection and transfusion dates of leukodepleted red blood cells from four hospitals in Enshi Prefecture from 2018 to 2022, as well as the information on transfusion adverse reactions, were retrieved. 【Results】 From 2018 to 2022, a total of 697 61 bags of leukodepleted red blood cells were transfused in four hospitals, resulting in 166 cases of transfusion adverse reactions, among which 93 were allergic reactions, 63 were non hemolytic febrile reactions, and 10 were others, with a total incidence rate of transfusion adverse reactions at 0.24%. The average storage time of leukodepleted red blood cells with and without transfusion adverse reactions was (20.25±6.31) and (19.88±5.50) days, respectively. With a storage time of 7 days as the threshold, the incidence of transfusion adverse reactions was the lowest for a storage time of 15~21 days. The incidence of transfusion adverse reactions of leukodepleted red blood cells in two groups (with storage days ≤21 days and >21 days) was not statistically significant(P>0.05). 【Conclusion】 Allergic reactions were the main type of transfusion adverse reaction caused by leukodepleted red blood cells, and the incidence of transfusion adverse reactions decreased and then increased with the prolongation of the storage time of leukodepleted red blood cells. There was no significant difference in the incidence of transfusion adverse reactions with leukodepleted red blood cells stored for ≤ 21 days and >21 days.
