【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.

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,

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.

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.

Objective To investigate the effect of moxibustion or acupuncture combined with prokinetic drugs (metoclopramide injection) on the success rate of placing the nasal and intestinal tubes in critically ill patients at bedside.Methods A total of 107 patients underwent enteral nutrition from January 2015 to August 2017 in the Intensive Care Unit (ICU) of Wenzhou Central Hospital in Zhejiang Province were recruited and given bedside manual placement of spiral nasointestinal tube. According to whether the acupuncture or moxibustion combined with the use of the prokinetic drugs in the process of placing the tube, the cases can be divided into three groups: simple prokinetic drugs group (n=23), moxibustion combined with prokinetic drugs group (n=22), acupuncture and moxibustion combined with prokinetic drugs group (n=62). The success rate of catheterization in three groups was analyzed and compared statistically.Results After 72 hours of catheterization, bedside X-ray abdominal radiography showed that the end of the catheter was located behind the pylorus in 81 cases out of the 107 patients. The success rate of catheterization was 75.70％. The unsuccessful patients were given gastroscopy guided nasointestinal tube. The success rate of catheterization was 30.43％ in simple prokinetic drugs group, 63.64％ in moxibustion combined with prokinetic drugs group, and 96.77％ in acupuncture and moxibustion combined with prokinetic drugs group. Comparing the success rate of the catheterization, the difference was statistically significant (χ2=49.75,P<0.01).Conclusions The combination of moxibustion and acupuncture can significantly increasing the success rate of placing the spiral nasointestinal tube, and provide practical benefits for the critically ill patients. This method should be popularized in clinic.

In this study, the standard research methods were applied to account the awards and applications of scientific research achievements of Xiyuan hospital from 2010 to 2014. As for the scientific research awards, each department from Xiyuan hospital was active, but the awards application offices were relatively few, thus the quantity of the awards was decreasing year by year. And the distribution was relatively uneven. The basic characteristics of scientific research awards showed that the National Science and Technology Award was the most difficult award. And other characteristics of scientific research award showed that it was often based on a project with high social recognition and high authority, and with the first researchers were high rank professors. This work cast light on that scientific research management should improve the quality of projects and strengthen exchanges, propaganda and introduction of each project achievement, enhance team establishment as support, and establish a reasonable assessment system for scientific research achievements.
