Objective: To analyze the adverse treatment outcome status and spatio temporal characteristics of pulmonary tuberculosis cases among students in Qinghai Province, providing a reference basis for pulmonary tuberculosis prevention and control in schools. Methods: The data of student pulmonary tuberculosis cases during 2013-2023 in Qinghai Province were obtained through the "National Tuberculosis Management Information System", and the treatment outcome was retrospectively analyzed. The Joinpoint model was applied to analyze the adverse outcome rate trend. Global and local spatial autocorrelation analysis, and spatiotemporal scan cluster analysis were conducted on the adverse outcome rate of pulmonary tuberculosis among students in Qinghai Province. Results: During 2013-2023, 488 cases of adverse outcomes were reported among 6 155 students with pulmonary tuberculosis in Qinghai Province, with an adverse outcome rate of 7.93%. The reporting adverse outcome rate of pulmonary tuberculosis among students showed a downward trend from 2013 to 2023 (APC=-16.20, t =-3.89, P <0.05). The results of spatial autocorrelation showed that the adverse outcome rate of pulmonary tuberculosis was Moran s I >0 among students in Qinghai Province. Among them, there was a spatially positive correlation in the adverse outcome rate of pulmonary tuberculosis among students in 2020, 2021 and 2022(all Z >1.96, all P <0.05). The results of clustering and outlier analysis in local spatial autocorrelation showed that the areas with high high aggregation were mainly concentrated in Yushu Prefecture(Zhiduo County, Zaduo County, Nangqian County, Yushu City), Huangnan Prefecture (Zeku County, Henan County) and Hainan Prefecture (Tongde County). The low low concentration areas were distributed in Haidong City, Xining City, Haibei Prefecture (Gangcha County, Qilian County), Haixi Prefecture (Tianjun County, Ulan County), Hainan Prefecture (Gonghe County, Guide County) and Huangnan Prefecture (Tongren City, Jianzha County). The spatio temporal scanning showed that a total of two possible aggregation areas had been detected. Among them, the first level aggregation area composed of 10 counties and districts in Yushu Prefecture and Guoluo Prefecture of Qinghai Province, and the cluster radius was 658.09 km, the RR was 10.58 , and the LLR was 305.91; the second level aggregation area was composed of 16 counties and districts in Hainan Prefecture, Haixi Prefecture, Huangnan Prefecture and Guoluo Prefecture, and the cluster radius was 407.02 km, the RR was 9.83, and the LLR was 152.48 (both P <0.05). Conclusions The reporting rates of adverse treatment outcome of pulmonary tuberculosis cases among students in Qinghai Province remain relatively high and unevenly distribute throughout the province. Supervision should be strengthened to improve cases compliance,and to reduce student pulmonary tuberculosis adverse treatment outcomes incidence.

Objective To construct a curriculum system for higher vocational education in speech-language-hearing rehabilitation based on the World Health Organization rehabilitation competency framework(RCF),to align with international standards. Methods Based on RCF,curriculum theory and principles of vocational education psychology,a curriculum system and its content for higher vocational education in speech-language-hearing rehabilitation were developed.The curric-ulum content and core competencies were analyzed in detail across four levels:basic courses,specialized basic courses,specialized core courses and practical training courses. Results From the perspective of the seven competency domains of RCF,the theoretical and practical significance of con-structing a speech-language-hearing higher vocational education curriculum system based on RCF was systemati-cally elaborated.The study emphasized the importance of establishing competency-oriented higher vocational re-habilitation education for developing students'professional competence,adapting to job requirements,and pro-moting career development.A curriculum content system for speech-language-hearing rehabilitation higher voca-tional education based on RCF was systematically constructed,encompassing basic courses,professional cours-es,and practical training courses.The course names,main content and competency objectives at each level were analyzed in detail. Conclusion It is important to develop the course system of higher vocational education of speech-language-hearing reha-bilitation based on RCF.By comparing with international standards,the curriculum is optimized,focusing on im-proving students'vocational competence and promoting the international development.The curriculum system covers key areas such as core values,beliefs,practice and professionalism,integrates basic,core and practical training courses to achieve a competence-oriented curriculum system for higher vocational speech-language-hear-ing rehabilitation education.

Conclusion It is valuable to develop the competency-based core curricula for speech-language-hearing rehabilitation technology using RCF,for advancing competency-oriented vocational education.These curricula not only align with the current demand for highly skilled professionals in the rehabilitation industry,but also lay a foundation for students'continuous professional development.By emphasizing practical skills and interdisciplinary collabo-ration,the courses enable students to effectively function in dynamic rehabilitation environments,meeting di-verse rehabilitation needs.

Objective To observe the effect of preoperative enteral nutritional support combined with modified Ivor-Lewis surgery for esophageal cancer on lung function and mRNA expression of GATA-binding protein 3(GATA3)and forkhead protein P3(Foxp3)in peripheral blood.Methods Sixty esophageal cancer patients who underwent modified Ivor-Lewis surgery in our hospital from January 2022 to October 2023 were selected and divided into two groups by simple random method.The control group was given conventional diet before operation,and the observation group was given enteral nutrition support before operation.The two groups were compared in terms of nutritional support.Results Both groups showed significantly decreases in one-second exertion expiratory volume/exertion lung volume(FEV1/FVC)(P<0.05),FVC(P<0.05),FEV1(P<0.05)and the levels of peripheral blood GATA3(P<0.05),Foxp3 mRNA(P<0.05)expression compared with those at admission(P<0.05),but no significant differences in pulmonary function(P>0.05),peripheral blood GATA3(P>0.05),and Foxp3 mRNA(P>0.05)expression between them at 1 week postoperatively.Both groups exhibited significantly lower levels of albumin,prealbumin,haemoglobin,transferrin,PNI and body mass and body mass index at admis-sion as compared to those at one week after surgery(P<0.05).The observation group showed significantly higher levels of albumin,prealbumin,haemoglobin,transferrin,and PNI at 1 week postoperatively(P<0.05),but no significant differences in ventilation time,defecation time,drain retention time,hospitalisation time,and compli-cation rate as compared to the control group(P>0.05).Conclusion Preoperative enteral nutritional support combined with modified Ivor-Lewis surgery for esophageal cancer improves postoperative nutritional status,and ren-ders less effect on postoperative lung function and peripheral blood GATA3 and Foxp3 mRNA expression.

Objective:To investigate the efficacy and safety of combined catheter-directed thrombolysis and anticoagulation for acute pulmonary embolism combined with lower limb deep vein thrombosis.Methods:A retrospective analysis was conducted using a case-control study approach on the clinical data of 58 patients with acute pulmonary embolism who received treatment at the Inner Mongolia Autonomous Region People's Hospital from August 2021 to August 2023. These patients were categorized into two groups based on whether they had lower-limb deep vein thrombosis or not. The group with pulmonary embolism alone ( n = 14) underwent targeted catheter thrombolysis in combination with anticoagulation treatment using low molecular-weight heparin. The group with both pulmonary embolism and deep vein thrombosis in the lower limbs (combined group, n = 44) received inferior vena cava filter placement, along with targeted catheter thrombolysis and anticoagulation treatment with low-molecular weight heparin. The improvement in pulmonary circulation was observed before and after the surgical interventions in both groups. A comparison was made regarding the improvement in indicators including arterial oxygen pressure, fingertip oxygen saturation, the proportion of pulmonary artery trunk thrombosis area to pulmonary artery trunk area, and respiratory rate, both before and after pulmonary artery catheterization and thrombolysis in both groups. Results:The surgery was successful for all patients. The symptom of shortness of breath was obviously relieved after surgery. After surgery, in the pulmonary embolism alone group, the respiratory rate was (22.75 ± 4.38) beats/min, the mean pulmonary artery pressure was (32.53 ± 3.63) mmHg (1 mmHg = 0.133 kPa), the arterial oxygen partial pressure was (81.46 ± 7.24) mmHg, and the fingertip oxygen saturation was (90.53 ± 4.57)%, respectively. In the combined group, the respiratory rate, mean pulmonary artery pressure, arterial oxygen partial pressure, and fingertip oxygen saturation were (23.35 ± 5.8) beats/min, (31.34 ± 4.53) mmHg, (82.34 ± 4.62) mmHg, and (92.57 ± 3.45)%, respectively. After surgery, the respiratory rate, pulmonary artery pressure, arterial oxygen partial pressure, and fingertip oxygen saturation in each group were significantly higher compared with the corresponding levels before surgery ( t = 6.33, 12.12, 17.32, 8.13, 6.86, 13.02, 15.52, 7.20, all P < 0.001). The proportion of pulmonary artery trunk thrombosis area to pulmonary artery trunk area in the group with pulmonary embolism alone was (19.56 ± 7.53)%, while in the combined group, it was (20.63 ± 4.83)%. After surgery, the proportion of pulmonary artery trunk thrombosis area to pulmonary artery trunk area in each group decreased compared with the corresponding value before surgery ( t = 19.36, 18.23, both P < 0.001). Conclusion:The surgical method combining catheter-directed thrombolysis with inferior vena cava filter placement is effective and safe for the treatment of acute pulmonary embolism combined with deep vein thrombosis in the lower limbs.

Objective To explore the value of artificial intelligence(AI)in the diagnosis of pulmonary nodules in terms of consistency and efficiency compared with two radiologists(physician 1 is a chief physician and physician 2 is a deputy chief physician)in the diagnosis of benign and malignant pulmonary nodules using computed tomography(CT).Methods Retrospective analysis of 201 patients with pulmonary nodules confirmed by surgery pathology at Hangzhou Municipal Hospital affiliated to Zhejiang Chinese Medical University from January 2021 to October 2022,including a total of 229 pulmonary nodules,of which 74 were benign and 155 were malignant.The consistency of AI diagnosis with two radiologists was evaluated by weighted Kappa test,and the diagnostic performance of AI with the two radiologists was evaluated by the receiver operating characteristic curve(ROC).Results In the diagnosis of the benign and malignant nature of partial solid nodules,ground-glass nodules,solid nodules,and partial ground-glass and solid plus ground-glass nodules,the consistency between AI and physician 2 was higher than that between AI and physician 1.Additionally,the area under the curve(AUC)of physician 2 was higher than that of AI and physician 1 with statistically significant differences between the AUCs of ground-glass nodules,solid nodules,and partial ground-glass and solid plus ground-glass nodules(P<0.05).In the diagnosis of the benign and malignant nature of partial solid nodules and ground-glass nodules,the AUC of physician 1 was higher than that of AI,but there was no statistically significant difference between the two(P>0.05).In the diagnosis of the benign and malignant nature of solid nodules and partial ground-glass and solid plus ground-glass nodules,the AUC of AI was higher than that of physician 1 with statistically significant differences between the two(P<0.05).In the diagnosis of the benign and malignant nature of ground-glass nodules,solid nodules,and partial ground-glass and solid plus ground-glass nodules,AI's sensitivity(97%,92%,and 94%)was higher than that of physician 1(58%,89%,and 72%)and physician 2(83%,84%,and 85%).Conclusion AI has a certain diagnostic efficacy in the diagnosis of pulmonary nodules malignancy.The overall diagnostic efficacy of the AI system used in this study is between that of physician 1 and physician 2,but its sensitivity is higher than that of the latter two.

Objective:The aim of this retrospective study is to evaluate the safety and efficacy of tislelizumab in patients with recurrent/metastatic head and neck squamous cell carcinoma. Methods:Six patients with recurrent/metastatic head and neck squamous cell carcinoma who received tislelizumab monotherapy in our hospital from 2018 to 2020 were retrospectively analyzed. The information of sex, age, TNM stage, efficacy, and adverse reactions were collected. All patients were recruited from the RATIONALE 102 study. The primary end point was the objective response rate, and other end points included progression-free survival and overall survival. We performed tumor immune-related gene sequencing and transcriptome sequencing analysis on the tumor tissues of the patient, and used bioinformatics methods to enrich immune cells and analyze signaling pathways. All analyses were performed using R 4.1. 0 software, SPSS Statistics 24.0 software and GraphPad Prism 8. Results:As of May 31, 2020, the median follow-up time was 26.35 months. The objective response rate with tislelizumab was 50.0%, the median progression-free survival was 6.44 months, and the estimated median survival was 20.07 months. The incidence of grade 3 or higher adverse reactions was 66.7%, including hyponatremia, hypokalemia, hypercalcemia, etc. The expression of macrophage, Treg and neutrophil-related genes are higher in immune-sensitive patients, and the signaling pathways of the intestinal immune network for IgA production, graft versus host disease and autoimmune thyroid disease are significantly activated. Conclusion:Tislelizumab was found to be controllable and tolerable in patients with recurrent/metastatic head and neck squamous cell carcinoma. The response to tislelizumab is related to immune cell infiltration and activation of immune-related signaling pathways.
