Cardiovascular surgery patients have complex and changeable conditions, and the nursing operation is highly specialized, and involves the use of a variety of high-precision instruments and high-risk drugs. Therefore, it's not only required that teachers should have solid theoretical knowledge, rich clinical experience, and good moral quality, but nursing interns also need to have active learning consciousness, adapt to the work intensity of the department in a short time and be familiar with the work content. Starting from the difficulties of clinical nursing teaching in cardiovascular surgery, this study puts forward measures such as attaching importance to the mobilization of nursing students before internship, strengthening the standardized management of clinical teaching, introducing diversified nursing teaching methods, and paying attention to the mental health of intern nurses during the practice, so as to improve the quality of nursing teaching.

Objective:To investigate the post competency of "Academic-Practical" of clinical nursing teachers, and analyze related influencing factors.Methods:A total of 312 "Academic-Practical" and "Non-Academic-Practial" clinical nursing teachers from The Affiliated Hospital of Southwest Medical University were surveyed by the Clinical Nursing Teacher Post Competency Evaluation Questionnaire. SPSS 20.0 software was used for t test, chi-square test and rank sum test. Results:The average self-evaluation scores of post competency of "Academic-Practical" clinical nursing teachers were (4.26±0.41) points, which were higher than those of the "Non-Academic-Practical" teachers [(3.19 ±0.50) points], showing good post competency. There were significant differences in the scores of professional quality (17.39±1.54), professional attitude (21.75±2.21), professional ability (21.14±2.31), teaching ability (50.39±5.93), interpersonal coordination ability (25.57±3.04), and personality characteristics (17.27±2.04) between the "Academic-Practical" and "Non-Academic-Practical" teachers (all P<0.01). And there were significant differences in self-evaluation post competency scores of "Academic-Practical" teachers in "with or without teacher qualification certificate" ( P=0.001), "whether she/he is the backbone of the department" ( P=0.002), degree ( P=0.001), age ( P<0.001), positional title ( P<0.001) and working year ( P<0.001) (all P<0.01). But there was no significant difference in gender ( P=0.735) and "whether she/he is a specialized nurse" ( P=0.335). Conclusion:"Academic-Practical" and "Non-Academic-Practical" medical teachers should take the post competency as the core orientation, adopt the "Ladder" mode of training and management, and constantly improve the training plan of post competencey.

Objective:To study the influencing factors of doctors′ compliance intention towards clinical pathways at diagnosis-related groups(DRG) pilot hospitals, as a reference in advancing the development of critical pathways management and the transition of DRG payment methods from pilot exploration to actual payment.Methods:With purposive sampling method, an online questionnaire survey was conducted on doctors at 4 tertiary hospitals involved in the DRG pilot in Wuhan from December 2020 to February 2021. The questionnaire covered doctors′ basic personal information, identification degree of three dimensions based on the theory of planned behavior, as well as their past compliance behavior and compliance willingness of clinical pathways. The influence of different factors on doctors′ clinical path compliance intention was analyzed by Kruskal-Wallis test and Wilcoxon signed-rank test, and the ordered multi-class logistic regression analysis was used in multivariate analysis.Results:335 valid questionnaires were obtained, of which 205(61.2%) doctors had high willingness to follow clinical pathways. Such factors as degree of attention to peer doctors′ attitudes towards clinical pathways( OR=16.44), sufficient understanding of the documents( OR=14.91), the adaptation between information systems and clinical pathways( OR=12.54), sufficient learning resources( OR=9.42), and high enrollment rate of their patients in charge in the past six months( OR=5.77), could positively affect the doctors′ willingness to follow clinical pathways. The high enrollment completion rate of patients cared by doctors in the past six months( OR=0.09) and the high mutation rate caused by medical prescriptions( OR=0.00) negatively affected doctors′ compliance intention towards clinical pathway. Conclusions:Most doctors at DRG pilot hospitals had high willingness to comply with the clinical pathways. The main factors affecting their willingness to follow the clinical pathway include, previous relevant work experience, the attitude of peer doctors, and support resources. To increase doctors′ compliance willingness towards clinical pathway, it is necessary to speed up the DRG payment process, adopt a flexible management model, enhance the sense of participation of doctors, and ensure adequate support vesources.

Objective To construct a telemedicine-based home care system of palliative care for end-of-life cancer patients,and to evaluate its application effect.Methods The construction of the system was based on the literature research,interview results of the patients and their caregivers,and expert group meeting discussions.From May to August 2023,a total of 88 patients,who were about to be discharged from the palliative care ward of a cancer hospital in Hunan Province,were selected as the study subjects using a convenient sampling method,and then they were divided into an experimental group and a control group according to the order of admission.The experimental group was given home care services based on the system,while the control group was given routine discharge guidance and follow-up visits.The duration of the intervention was 8 weeks.The Chinese version of the Edmonton Symptom Assessment Scale and the Chinese version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 palliative were used to evaluate the symptom burden and quality of life between 2 groups before and after intervention;the Telemedicine Satisfaction Questionnaire was used to evaluate the care satisfaction of the experimental group.Results The system of patient side includes 8 main features,namely personal health record establishment,doctor-patient communication,palliative care knowledge library,medication assistance,smart reporting and monitoring,intelligent Q&A,intelligent follow-up,and intelligent forms.The healthcare professional side includes 7 main functions,namely workbench,case management,follow-up management,warning reminder,popularization push,statistical analysis and user management.A total of 67 patients completed the intervention,with 33 in the experimental group and 34 in the control group.The symptom burden of the experimental group was lower than that of the control group(P＜0.05);the quality of life in the experimental group was better than that in the control group(P＜0.05);the score of care satisfaction was(59.00±6.66),which indicated a high level of satisfaction.Conclusion The system can reduce the symptom burden and improve the quality of life of end-of-life cancer patients with good practicality

Compared with the global average, the incidence rate of nasopharyngeal carcinoma (NPC) in China is higher, particularly in the southern regions where the mortality rate has remained persistently high. Nimotuzumab, a targeted therapy that acts on the epidermal growth factor receptor, has prompted continuous progress in NPC treatment. The combination of nimotuzumab with traditional radiotherapy and chemotherapy can enhance treatment efficacy, reduce adverse reactions, and improve patients’ quality of life. This article summarizes current research findings from this perspective to provide diagnostic and therapeutic strategies for NPC treatment.

Background It is a research hotspot to study the changes of metabolites and metabolic pathways in the process of coal worker's pneumoconiosis (CWP) by metabonomics and to explore its pathogenesis. Objective To study the change of metabolites in bronchoalveolar lavage fluid (BALF) of patients with CWP and explore the metabolic regulation mechanism of the disease. Methods Patients with CWP who met the national diagnostic criteria according to Diagnosis of occupational pneumoconiosis (GBZ 70-2015) and underwent massive whole lung lavage were selected as the case group, and patients with tracheostenosis who underwent bronchoscopy were selected as the control group. BALF samples were collected from the cases and the controls. After filtering out large particles and mucus, the supernatant was stored in a −80 ℃ refrigerator. The samples were detected and analyzed by liquid chromatography-mass spectrometry after adding extraction solution, cold bath ultrasonication, and high-speed centrifugation, and the metabolic profiles and related data of CWP patients were obtained. The differential metabolites related to the occurrence and development of CWP were screened by multiple statistical analysis; furthermore, we searched the Kyoto Encyclopedia of Genes and Genomes (KEGG) database for potential metabolic pathways involved in the progression. Results There was no significant difference in the general conditions of the subjects, such as weight, height, age, and length of service among the stage I group, the stage II group, the stage III group, and the control group (P˃0.05). When comparing the CWP stage I group with the control group, 48 differential metabolites were screened out, among which 14 were up-regulated and 34 were down-regulated. A total of 66 differential metabolites were screened out between the patients with CWP stage II and the controls, 14 up-regulated and 52 down-regulated differential metabolites. Compared with the control group, 63 differential metabolites were screened out in the patients with CWP stage III, including 11 up-regulated and 52 down-regulated differential metabolites. There were 36 differential metabolites that may be related to the occurrence of CWP, among which 11 differential metabolites were up-regulated, and 25 were down-regulated. Four significant differential metabolic pathways were identified through KEGG database query: linoleic acid metabolic pathway, alanine metabolic pathway, sphingolipid metabolic pathway, and glycerophospholipid metabolic pathway. Conclusion The metabolomic study of BALF show that there are 36 different metabolites in the occurrence and development of CWP, mainly associating with linoleic acid metabolism, alanine metabolism, sphingolipid metabolism, and glycerophospholipid metabolism pathways.
