Research progress in quality studies and antiviral effect of Qingyan Dropping Pills / 国际生物医学工程杂志

Qingyan Dropping Pills have the effects of relieving wind and heat, detoxifying, and promoting the pharynx. It is commonly used in traditional Chinese medicines to treat acute and chronic pharyngitis, as well as sore throats and dry throats caused by surgery. Recently, many studies have shown that Qingyan Dropping Pills have certain effects on bacteriostasis, anti-inflammatory, antioxidant, and antiviral activities. As the coronavirus disease 2019 (COVID-19) pandemic enters the post-epidemic era, the regular use of drugs for COVID-19 pandemic symptoms has become a new trend. Therefore, there is a good market prospect to explore and develop Chinese patent medicines with antiviral effects. A preliminary study on the herbal formula and material basis of Qingyan Dropping Pills revealed that they have potential for antiviral applications. In this paper, the research on the quality study and antiviral effect of Qingyan Dropping Pills was reviewed, and the research direction of its secondary development was discussed to provide ideas and references for the new use of old traditional Chinese medicines.

The application of Kirkpatrick Model in the evaluation of standardized training effect of new nurses / 中国实用护理杂志

Objective:To evaluate the effect of standardized training for new nurses in the first year based on Kirkpatrick model as a theoretical framework.Methods:A cross-sectional study was conducted. New nurses' satisfaction with training, theoretical and operational assessment, job performance, core competence, turnover rate and other indicators were used, to evaluate the effect of standardized training for 62 new nurses in the first year.Results:At the reaction level, the overall satisfaction score of new nurses was 4.66±0.47; at the learning level, the theoretical assessment score was 95.32±2.38, the operational assessment score was 97.53±1.07, and the performance score was 97.12±1.64; at the behavioral level 88.45±9.75; and at the result level, there were no complaints and errors among new nurses, and the turnover rate was 1.6% (1/62). The theoretical and operational assessment scores were positively correlated with work performance, with r value of 0.424 and 0.399, respectively, and P = 0.001. The theoretical assessment scores were negatively correlated with the behavioral level, with the r value of -0.264 and P= 0.038. There were no correlation with the operational assessment scores and the behavioral level, with the r value of 0.147 and P value of 0.253. Conclusions:Kirkpatrick model validates the standardized training program for new nurses effectively, and provides scientific basis for improving the training program for new nurses. The results level of the training needs to be evaluated in the long term.

A status survey on clinical teaching towards postgraduates of master of nursing specialist in China / 中国实用护理杂志

Objective:To investigate the current status of clinical teaching towards postgraduates of master of nursing specialist(MNS) in China.Methods:Objective sampling was used to invest 390 MNS clinical nursing teachers in 36 hospitals across the country. The survey included the admission and evaluation criteria of teachers, the MNS postgraduates′ clinical teaching plan and implementation, and the assessment of MNS postgraduate ′s clinical practice ability, etc. Results:Among the criteria for clinical teachers for MNS postgraduates, 79.49% of departments required bachelor ′s degree or above, and 67.18% of departments requested medium-grade professional title or above; 47.44% of the departments demanded that clinical teachers had the research experience, 58.21% departments asked for the experience of articles publication. The main method of selecting clinical teaching teachers was examination (50%), while 31.28% departments had no definite criteria. The evaluation indicators of clinical teachers mainly depended on the results of students ′ clinical practice capability assessment (81.79%) and students ′ satisfaction (80%). Only 49.23% of the study objects knew the training objectives of MNS. The pivotal abilities of MNS graduate students were the ability of clinical nursing practice (91.79%) and clinical research (82.82%). The MNS postgraduate teaching plan of each department was mainly derived from the requirements of tutors and colleges (87.69%). The mode of clinical teaching was that one student was guided by a fixed clinical teacher (87.18%). Clinical practice assessment methods of MNS mainly included theoretical knowledge assessment (88.46%) and the performance of section lectures (82.56%). The assessment personnel were mainly clinical teachers (95.40%) and head nurses (83.51%). The self-assessment of clinical teachers was rated at the medium level about their performance on the postgraduate MNS students ′ clinical teaching. Conclusions:The homogenization and standardization of the construction of MNS clinical teaching base needs to be improved in China. In the field of defining the criteria of clinical teaching teachers, strengthening the construction of clinical faculty, perfecting the clinical teaching plan and evaluation system according to the cultivation objectives and specialist characteristics, and elevating the comprehensive medical education combined with clinical education and college education, further exploration is indispensable.

Novel deletion of SLC34A2 in Chinese patients of PAM shares mutation hot spot with fusion gene SLC34A2-ROS1 in lung cancer.

Pulmonary alveolar microlithiasis (PAM) is an autosomal recessive disorder with distinctive deposition of calcium phosphate microliths in the lungs. Mutation of the SLC34A2 gene was proved to be responsible for PAM. Here, we report the study of a family affected by PAM in China. Two daughters of an inbred family whose parents are cousins and are affected by PAM. Mutation analysis of the SLC34A2 gene by polymerase chain reaction (PCR) amplification and direct sequencing in both patients revealed that exon 5 was deleted on both alleles. Both parents of the patients are proved to be carriers of the mutated allele. Gap-PCR was performed to determine the breakpoints and a homologous deletion of 1152 bp encompassing exon 5 of the SLC34A2 gene (c.IVS4+1452_IVS5+660del) was confirmed. A 4-bp fragment of TGGG was located on the edge of both upstream and downstream breakpoints. The upstream breakpoint lies in the same region as the breakpoint of a fused gene SLC34A2-ROS1, which encodes a constitutive kinase in the lung cancer cell line HCC78 and nonsmall-cell lung cancer (NSCLC), suggesting that the deletion in this family is a hot spot for recombination, not only in cancer samples with somatic mutation, but also in PAM patients with germline genetic defects of SLC34A2.

Reflections on the teaching competition of young teachers in medical colleges / 中华医学教育探索杂志

National Teaching Contests of young teachers from medical colleges in China has been held for several years. Experiences obtained from participating and observing the contest have shown that the teaching ability and quality of young teachers have been dramatically improved over these years. But there are a few problems worthy of attention. First, up-to-date progress in scientific research should be intro-duced to the class in proper way. Applying the scientific material mechanically or overgeneralizing individual findings should be avoided in this process. Secondly, the teachers should strengthen the cultivation of criti-cal thinking and dialectical way of thinking, to enable students to use critical thinking, the integrated point of view to analyze and solve the problem. Thirdly, teaching should also focus on humanistic education, and through the infiltration of human content in the classroom, imperceptibly affect students. Finally, young teachers can give full play to their advantages of rapid learning and to use internet as a platform for the reform of teaching methods to promote the interaction between teachers and students, enriching their class-room.
