Objective To investigate the expression changes of serum long non-coding RNA rhabdomyosarcoma associated transcript-2 (LncRNA RMST) and miR-582-5p in patients with acute ischemic stroke (AIS),and their correlation with early neurological deterioration (END) and prognosis. Methods A total of 129 patients with ischemic stroke admitted to Chengde Central Hospital from January 2021 to December 2022 were gathered,according to diagnostic criteria and patients were divided into END group (n=42) and non END group (n=87) besed on whether END occurred within one week. In addition,59 healthy individuals who underwent physical examination in the hospital were regarded as the health group. The real-time fluorescence quantitative polymerase chain reaction method was applied to detect serum LncRNA RMST and miR-582-5p levels in each group. The Pearson method was used to analyze the correlation between serum LncRNA RMST and miR-582-5p levels in END patients. ROC curve was applied to evaluate further the levels of blood LncRNA RMST and miR-582-5p,and the efficacy analysis of their combination in predicting the prognosis of AIS patients. Results Serum LncRNA RMST(1.01±0.28,2.10±0.41,3.99±0.52) levels gradually increased in the healthy,non-END and END groups,and miR-582-5p(1.02±0.23,0.86±0.16,0.73±0.15) levels gradually decreased,and the differences were statistically significant (F=672.974,31.907,all P<0.05). There was a significant negative correlation between serum LncRNA RMST levels were significantly negatively correlated with miR-582-5p levels (r=-0.451,P<0.001). The AUC(95％CI) of the combined diagnosis of serum LncRNA RMST and miR-582-5p levels in AIS patients was 0.961(0.912～0.987),which was better than the independent prediction (Z=2.280,4.515,all P<0.05). Conclusion The levels of serum LncRNA RMST and miR-582-5p were closely related to END,and they are expected to become predictive factors for the prognosis of AIS patients.

The traditional teaching model centered on courses has disadvantages such as interdisciplinary barriers, repetitive learning of content, and students being unable to enter clinical practice early. The Human Body Overview I is a core course at the basic stage under the integrated curriculum system centered on "organ-systems" at Chongqing Medical University. The course deeply integrates interdisciplinary resources and reconstructs the contents of systematic anatomy, embryology, and physiology under the traditional teaching model. The "Three in One" curriculum ideology and politics are implemented to assist students in their comprehensive development. By strengthening the cultivation of clinical application abilities and empowering with virtual simulation technology, the teaching effectiveness and quality have been improved. The teaching practice of the Human Body Overview I suggests that the teaching reform of integrated curriculum at the basic stage has broken interdisciplinary barriers, avoided repetitive learning of contents, and promoted the cultivation of students' interdisciplinary integration ability and clinical application ability. It can provide a reference for the teaching reform of integrated curriculum for other colleges.

【Objective】 To investigate the resource allocation status of blood testing laboratories in 14 blood stations in Gansu Province, explore the impact of differences in basic conditions on the comprehensive testing ability of laboratories, so as to promote the homogenization and standardization of blood screening capacity in blood stations in Gansu and improve blood safety and effectivenes. 【Methods】 An evaluation index system of laboratory resource allocation was constructed and a question-naire was designed. The data of human resources, infrastructure and key equipment of 14 blood stations were collected. The entropy weight -TOPSIS method was used to evaluate and rank the resource allocation of 14 blood stations. 【Results】 In the comprehensive evaluation of blood testing laboratory resource allocation in 14 blood stations in Gansu, the top three were laboratories A, B and I, and the last three were laboratories G, M and J. On the whole, the main issue was unreasonable structure of human resources: most laboratories had unreasonable age structure; except for Laboratory A, there was no personnel with bachelor's degree or above in laboratories; most laboratories had not established a team with intermediate professional titles. In terms of infrastructure, the size of seven laboratories could not meet the needs of modern laboratory testing, and all eight blood stations had no spare nucleic acid laboratories nor a mutual spare laboratory with other blood stations As for the key equipment, 5 laboratories had no automatic blood grouping diagnostic instrument, 5 laboratories only had one set of enzyme immunoassay detection system, 3 laboratories had no spare equipment for the key equipment, which means if the equipment failure could not be repaired in time, the release of results would be affected. 【Conclusion】 There were significant differences in human resources, infrastructure and key equipment of blood testing laboratories in 14 blood stations in Gansu, which had a great impact on laboratory testing capacity and subsequent development. It is suggested that governments at all levels and health administrative departments optimize the input of laboratory resource allocation according to the blood collection volume of blood stations to gradually narrow the differences in resource distribution between different regions, improve the degree of laboratory automation and optimize the personnel structure, so as to build high-quality and efficient blood testing laboratories and ensure the safety of clinical blood use.

The traditional teaching mode of "subject-centered" has many shortcomings such as knowledge separation and lack of integrity. In order to make up for the deficiencies of this mode, the organ-system integrated medical teaching mode has gradually become the trend of medical teaching reform. Taking "motor system" as an example, this paper discusses the practice of the organ-system integrated medical teaching mode from four aspects: teaching implementation, teaching quality supervision, supporting assessment system and teaching effectiveness.

Urea transporters (UT) play a vital role in the mechanism of urine concentration and are recognized as novel targets for the development of salt-sparing diuretics. Thus, UT inhibitors are promising for development as novel diuretics. In the present study, a novel UT inhibitor with a diarylamide scaffold was discovered by high-throughput screening. Optimization of the inhibitor led to the identification of a promising preclinical candidate,

It is an important way to improve the teaching quality by carrying out innovative experiments among medical students. In the process of experimental teaching, anatomy teachers expand the anatomy knowledge to basic scientific research techniques, so as to enhance students' confidence in participating in innovative experimental projects. Meanwhile, the teachers combine introduction of the anatomical structures with hot medical research issues, in order to help students to select appropriate innovative experimental topics. What's more, the new media teaching is integrated into the teaching of anatomy, enlightening students to perfect the experimental designs. Finally, in the teaching practice of regional anatomy, students are guided to carry out innovative experiments and write research papers. Abovementioned measures not only improve the teaching quality of anatomy, but also improve the students' scientific research ability, laying a foundation for them to participate in innovative experimental projects.

The excel statistical software and standard research methods were applied to account the application and approval rates of NSFC of Xiyuan Hospital of CACMS in the recent 3 years. The application and feedback issued by NSFC were collated and analyzed in this paper. From the foundation management, all departments had higher enthusiasm on project application, but departments applied were relatively centralized. The approval rates had risen steadily in the past 3 years. And approved projects mainly focused on departments of cardiovascular, hematology, spleen and stomach, geriatrics and basic medicine. However, no higher level projects were not supported successful by NSFC. And research awards for Xiyuan Hospital were mainly supported by the Ministry of Science and Technology and NSFC. In order to enhance successful rates of application and guarantee development of science research more sustainable, rapid and healthy, enthusiasm of researchers should be stimulated; quality of declaration should be improved; new mechanism of scientific research management need be perfected; and a good research environment should be built.
