ABSTRACT
Objective:To understand the development trend of scientific research in major medical institutions in China from 2019 to 2021.Methods:The PubMedplus database was searched, and the distribution of papers, published journals and its′ influencing factors (IF) of top 30 domestic medical institutions from 2019 to 2021 were statistically analyzed.Results:From 2019 to 2021, 84 405 PubMed papers were published by the top 30 medical institutions, including 79 459 papers in English, accounted for 94.14%, and 4 946 papers in Chinese, accounted for 5.86%. Of them, 22 447, 29 540 and 32 430 papers were published in 2019, 2020 and 2021. 75 240 papers in English were indexed by SCI database (89.14% of total English papers). 17 729 papers (accounted for 21.00%) were published by the top 27 journals, Frontier in Oncology ranks first. 4 400 papers (5.85% of total) were published by the journals of impact factors greater than 10. The biggest portion of the papers, 26 550 papers (35.29% of total) were published by the journals of impactor factor from 3 to 5. Conclusions:The quantity and quality of papers published by major medical institutions in China have been greatly improved each year. The progress level of medical institutions is different, and their advantageous disciplines of medical institutions have been well reflected.
ABSTRACT
Objective To investigate the trunk stability control of spastic cerebral palsy patients,and to analyze their visual compensation and the resulting symmetrical balance of the trunk.Methods Twenty children with spastic cerebral palsy and 20 healthy children formed the experimental and control groups respectively.Their balance was tested using the PK 254P rehabilitation system.Trunk stability and symmetry parameters were measured in standardized silent sitting for 30s with the eyes open and closed.The anterior-posterior (AP) and mediolateral deviations of the center of pressure (COP),the average speed of COP excursions in each direction,the COP perimeter,and the ellipse area of the COP were quantified.Results The two groups showed statistically significant differences in the average values of all the variables measured.The differences in the trunk stability control parameters of the experimental group between the eyes-open and eyes-closed conditions were significantly greater than those of the control group.The offset of the medial-lateral COP in the spastic cerebral palsy subjects was nearly symmetrical (the average position of the COP on the X axis was close to zero),while the anterior-posterior offset tended to the anterior direction (the average position of the COP on the Y axis was significantly positive).The medial-lateral and anterior-posterior offsets of the health subjects were nearly symmetrical (both close to zero).Conclusion Children with spastic cerebral palsy have less trunk stability control than healthy children.They rely more on visual cues in compensation.Their medial-lateral COP control is nearly symmetrical,but their anteriorposterior posture tends to the anterior.
ABSTRACT
Objective To evaluate the academic level and the popularity of Chinese Journal of Radiation Oncology Methods According to the information of Chinese Medical Citation Index(CMCI),statistically analyzed the amount and distribution of the originals in Chinese Journal of Radiation Oncology cited by the journal included by CMCI.Results The proportion of cited articles for original articles,short report and review were(73.8%),58.1% and 60.7% respectively,and average cited numbers for them were 7.2,3.0 and 3.4.The average of original articles cited by other researchers is 3.9,and there are more articles cited than other journal.The authors of these articles are from the 27 province/or municipalities,Beijing and Shanghai municipalities are in the front of Radiation Oncology research.There are 320 citing journals,and self-citing rate is 9.4%.Conclusions The Chinese Journal of Radiation Oncology has published high quality articles,and has its own edition characteristics to keep its steady level of research.It is the one of the most important information resource for the radiation oncology researchers and the most important medical journal.
