Objective To investigate the screening results and factors affecting abnormal detection rates among high-risk groups of esophageal cancer and to explore effective intervention measures. Methods We investigated and collected the information on gender, education level, age, marital status, symptoms of reflux esophagitis (heartburn, acid reflux, belching, hiccup, foreign body sensation in the pharynx, and difficulty swallowing), consumption of pickled vegetables, salt use, and esophageal cancer incidence of villagers in a natural village in Wenfeng District, Anyang City, Henan Province. Changes in reflux esophagitis symptoms in the high-incidence area of esophageal cancer before and after 16 years were observed, and the relationship of such changes with esophageal cancer was analyzed. Results In 2008, 711 cases were epidemiologically investigated, including 213 cases with one of the symptoms of reflux esophagitis such as heartburn, acid reflux, belching, hiccups, foreign body sensation in the pharynx, and difficulty swallowing (sorted in accordance with the abovementioned symptoms; if there are multiple symptoms, then the former is taken); 55 cases with at least two related symptoms, among which the most symptom was heartburn in 108 cases (15.1%); followed by acid reflux, belching, etc. In 2024, the same group of people was investigated, and eight people were missing because of relocation. A total of 703 people were successfully investigated, of which 189 cases (26.8%) had one of the symptoms of reflux esophagitis, such as heartburn (sorted in accordance with relevant symptoms, if there are multiple symptoms, then the former will be selected); 167 cases (23.7%) had at least two related symptoms, among which the most symptom was heartburn in 139 cases (19.7%); followed by acid reflux. Over 16 years, among the 703 people investigated, 45 cases had esophageal cancer and they had one or more of the abovementioned symptoms. No significant differences in the reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.26); no significant differences in the composition of reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.299). Conclusion The detection rate of reflux esophagitis-related symptoms in the population in a high-risk area of esophageal cancer has not decreased in the past 16 years, and the high-risk factors still exist. Esophageal cancer is closely related to reflux esophagitis, and clinical practice can provide early diagnosis and treatment for high-risk population.

Objective To understand the disease spectrum of a natural village in an area with high incidence of esophageal cancer to provide a reference for precise prevention and control. Methods From 2008 to 2024, 711 asymptomatic people over the age of 35 years in a natural village with high incidence of esophageal cancer in China were surveyed, and 171 of them were subjected to gastroscopy, biopsy, and pathological examination. All participants were followed up for a long time, and their disease history was recorded. Results A total of 16 years of follow-up were performed, and 703 people were effectively followed up. In 2008, 171 people underwent gastroscopy, and 160 people had biopsy and pathological results in endoscopic screening. By 2024, 76 people had been diagnosed with malignant tumors of 12 different types, and among these people, 45 had esophageal cancer. Conclusion Esophageal cancer remains a significant cause of morbidity and mortality from malignant tumors in this region. Biopsy and pathological examination should be strengthened during gastroscopy, and follow-ups and regular check-ups should be given high importance to reduce the incidence and mortality rates of esophageal cancer.

Objective:To investigate the effect of mucosal thickness around implants on marginal bone resorption.Methods:A retrospective analysis was conducted on the clinical data of 75 patients who received single-tooth implant restorations at Shaoxing Stomatological Hospital from December 2020 to May 2022. The patients were divided into two groups based on mucosal thickness: the thin gingiva group ( n = 40) and the thick gingiva group ( n = 35). In the thin gingiva group, implants were placed 1.5 mm below the bone surface, while in the thick gingiva group, implants were placed at the bone surface. Implant survival rates, marginal bone resorption, bone remodeling, and the incidence of adverse reactions were compared between the two groups. Results:The implant survival rate in the thin gingiva group was significantly lower than that in the thick gingiva group [75.00% (30/40) vs. 94.29% (33/35), χ 2 = 5.17, P < 0.05]. After 9 months of weight bearing, marginal bone resorption value in the thin gingiva group was significantly higher than that in the thick gingiva group [(0.16 ± 0.04) vs. (0.14 ± 0.02), t = 2.83, P < 0.05]. The bone remodeling value in the thin gingiva group was significantly lower than that in the thick gingiva group [(1.03 ± 0.21) vs. (1.25 ± 0.34), t = 3.48, P < 0.05]. The incidence of adverse reactions including infection, bleeding, occlusal weakness, and pain in the thin gingiva group was significantly higher than that in the thick gingiva group [25.00% (10/40) vs. 5.72% (2/35), χ 2 = 5.17, P < 0.05]. Conclusion:A mucosal thickness of ≥ 3 mm is associated with a higher survival rate of implants placed below the bone surface, which better maintains bone tissue stability, reduces bone resorption, promotes bone remodeling, and decreases the incidence of adverse reactions.

Objective:To systematically appraise and summarize existing evidence on enteral nutrition in patients receiving radiotherapy for head and neck cancer.Methods:Based on the 6S Pyramid of Evidence-based Resources, a systematic search was conducted to identify guidelines, expert consensuses, and evidence summaries related to enteral nutrition for radiotherapy patients with head and neck cancer published from January 2018 to September 2023. The search covered relevant websites of guidelines, websites of academic societies, and databases (in Chinese and English). Literature screening, quality assessment, and data extraction were performed independently by the researchers.Results:A total of 19 studies were included, consisting of 10 guidelines, 7 expert consensuses, and 2 evidence summaries. Four aspects and 67 items of best evidence on organizational management, nutritional screening and assessment, enteral nutritional intervention programs, and monitoring and follow-up were summarized.Conclusion:This study summarized the best evidence for enteral nutrition in patients receiving radiotherapy for head and neck cancer, which can inform the standardized nutritional management and promote the translation of evidence-based knowledge into practice.

Objective:To explore influencing factors of the self-reported brief life quality satisfaction score(Brief-QoL) in patients with acromegaly and understand the persistent low Brief-QoL scores in cases achieving biochemical remission.Methods:This study included 836 acromegaly patients who were hospitalized at Peking Union Medical College Hospital between January 2012 and December 2020. We retrospectively examined how clinical characteristics, biochemical parameters, comorbidities, and symptoms influenced Brief-QoL. Among patients who achieved biochemical remission, differences in clinical symptoms and comorbidities were analyzed between the high and low quality of life groups.Results:Patients with well-controlled biochemical indicators at the last follow-up had generally high Brief-QoL. However, patients with symptoms such as headaches (47.8% in the low-score group vs 14.9% in the high-score group, P<0.001) and joint pain (69.6% in the low-score group vs 19.0% in the high-score group, P<0.001) had low Brief-QoL despite biochemical remission. Receiving combined treatment(52.4% in the low-score group vs 27.5% in the high-score group, P=0.030) and having comorbid diabetes or hyperlipidemia were significant factors leading to decreased quality of life. Conclusion:Brief-QoL is suitable for follow-up of outpatient patients. Early identification of factors affecting quality of life and timely intervention can facilitate the realization of standardized management.

Objective To explore the professionalization model of nursing management team in an international medical center in a provincial public tertiary hospital.Methods Through literature research and Delphi method,a three-person nursing management team was established respectively in three nursing units:outpatient,first-ward,and second-ward of the center,and then trained professionally to define management boundaries and responsibilities.The training effect was verified by applying the professionalization management in the international medical center.The three nursing teams(nine nurses totally)were compared in terms of leadership,patient satisfaction,and nursing discipline construction before and after the training.Results Following the training,the three teams all exhibited a significant improvement in leadership as well as its dimensions(P＜0.05),and pa-tient satisfaction(P＜0.05).Additionally,care quality,scientific research capacity,and innovation ability were all elevated across the three groups.Conclusion The establishment of a nursing management team and performance of professional training can effectively promote the concept of professionalization management,improve the leadership of nurses,cultivate talent eche-lons,drive the overall development of disciplines and teams,and expand the connotation of nursing culture.For all these bene-fits,this model is suitable for promotion and application among clinical departments.

Objective To investigate the current status of off-label drug use(OLDU)management in tertiary hospitals of Guizhou province and to provide baseline evidence for developing a unified administration regulation for OLDU in Guizhou province.Methods In line with the relevant policies and regulations,a questionnaire including basic information about the person filling out the form,basic information about the hospitals,and information about OLDU was developed.The questionnaire was sent to 84 tertiary hospitals in Guizhou province through the Wenjuanxing.Results A total of 84 questionnaires were distributed and recovered,with a response rate of 100.00%.Of the 84 hospitals,77 had OLDU,of which 68(88.31%)had established a management system for OLDU.Among the 77 hospitals with OLDU,65(84.42%),42(54.55%),58(75.32%),36(46.75%),15(19.48%),and 21(27.27%)hospitals respectively,required approval from the Committee on Drug Administration and Pharmacotherapy before OLDU,restricted the qualifications of doctors prescribing OLDU,required informed consent from patients or their families before OLDU,recorded the matters and reasons in the medical records of patients treated with OLDU,followed up patients in their files and evaluated the reasonableness of the OLDU,and carried out special reviews for OLDU.Only 30(38.96%)hospitals have set up a catalogue of OLDUs,and 58(75.32%)hospitals have urgent needs to set up a unified provincial catalogue of OLDUs.Conclusion The pharmacy administration level of OLDU in tertiary hospitals of Guizhou province is relatively low,so there is an urgent need to establish a unified OLDU management system and medication catalog.

Objective:To investigate the necessity of internal fixation of the fibular fracture in the treatment of degree Ⅱ ankle supination-external rotation injury by the Dias-Tachdjian classification in children.Methods:A retrospective study was conducted to analyze the data of 69 children with ankle fracture (degree Ⅱ ankle supination-external rotation injury by the Dias-Tachdjian classification) who had been treated at Department of Orthopedic Trauma, The People's Hospital of Weifang and Department of Pediatric Orthopedics, Tianjin Hospital from January 2015 to October 2021. There were 41 males and 28 females with an age of (10.1±1.4) years, and 37 left and 32 right sides affected. The patients were divided into 2 groups according to whether internal fixation of the fibular fracture was performed. Group A consisted of 21 cases with fibular internal fixation and group B of 48 cases without fibular internal fixation. The preoperative data, operation time and operation expenses were recorded and compared between the 2 groups. At the last follow-up, the anteroposterior and lateral radiographs of bilateral full length lower limbs and ankle joints were taken; the lateral distal tibial angle (LDTA) and the anterior distal tibial angle (ADTA) on the affected side, and the disparity between bilateral ankle tibiotalar angles were measured; ankle function was assessed according to the ankle-hindfoot score of American Association of Foot and Ankle Surgery (AOFAS); the occurrence of premature physeal closure (PPC) was recorded.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (19.5±4.1) months. At the last follow-up, the LDTA on the affected side was 89.6° (87.9°, 90.5°) in group A and 88.6°±1.9° in group B; the ADTA on the affected side was 80.9° (79.0°, 81.4°) in group A and 80.0° (78.6°, 81.2°) in group B; the disparity between bilateral ankle tibiotalar angles was 1.1°±0.5° in group A and 1.2°±0.5° in group B; the AOFAS ankle-hindfoot score was (89.5±5.2) points in group A and 89.0 (87.0, 92.0) points in group B. There was no statistically significant difference between the 2 groups in the above items ( P>0.05). The incidence of PPC was, respectively, 14.3% (3/21) and 14.6% (7/48) in groups A and B, showing no statistically significant difference ( P>0.05). Conclusions:In the treatment of degree Ⅱ ankle supination-external rotation injury in children, internal fixation of the fibular fracture has no significant effect on the imaging angles or the function of the ankle joint. After anatomic reduction of the distal tibia, the fibular fracture can be treated without internal fixation to reduce operational trauma, shorten operation time and reduce operation expenses.

ObjectiveTo provide scientific support for the compilation of high-quality anti-nuclear， biological， and chemical （NBC） medical textbooks in China by retrieving books in the field of biological weapons defense in China， summarizing the publication time and distribution of publishing institutions， and categorizing content and key points of related books. MethodsRelevant subject terms in the field of biological weapons defense were searched through the official website of China National Digital Library and other websites， up until December 31， 2023， and were limited to books. Topic analysis was conducted on the introductions and contents of the books using the latent Dirichlet allocation （LDA） model. The number of topics was determined based on perplexity， and topics were identified according to the intertopic distance map， followed by a qualitative description of the core content of each topic. ResultsA total of 104 books were included in this study， among which four were identified as higher educational textbooks. The volume of publications increased during the periods 2002‒2004 and 2020‒2023. Research institutions accounted for the highest percentage of publishers （37.78%）， and 56.67% of the publishers were military institutions. The study identified six topics： "distribution， defense， and response to biological weapons"， "category， diagnosis， and treatment of biological warfare agents"， "response to biological public health emergencies"， "status of nuclear， biological， and chemical weapons internationally"， "biosafety risk management and prevention and control"， and "technologies and equipment related to biological hazard identification". ConclusionThere are few books in the field of biological weapons defense in China and the content is relatively outdated. In the future， the preparation of teaching materials should be aimed at practical emergency handling techniques for biological weapons， enhance the emphasis on biological weapons detection and biological warfare early warning， improve the fundamental theories at different training levels， and timely update the current research status in the field.
