RESUMO
Objective:To optimize the Manchester needs tool for injured children (MANTIC) scale , and evaluate its reliability and validity among injured children. Methods:The MANTIC scale was optimized through Delphi expert consultation and pre-tests. From March 2023 to June 2023 , a total of 317 injured children admitted in 7 level A tertiary hospitals in Zhejiang and Shandong provinces and their families were surveyed with general data, optimized MANTIC scale, and EuroQol 5-dimension health questionnaire for youth (EQ-5D-Y). Item analysis was conducted on the data of the 317 patients collected with optimized MANTIC scale through the test for homogeneity and value-based decision-making method and the content validity test of the scale was evaluated with item-level content validity index (I-CVI) and scale-level content validity index (S-CVI). It was evaluated with KMO test values and Bartlett′s test of sphericity to determine whether the scale was suitable for exploratory factors. The number of common factors was determined based on the K1 criterion and scree plot to further obtain the structural validity of the scale of the item load value. The correlation validity of the scale was evaluated with the correlation coefficient of the optimized MANTIC scale and EQ-5D-Y. The reliability of the scale was tested with Cronbach alpha coefficient and Guttman split-half reliability coefficient. Results:A total of 332 questionnaires were distributed, among which 317 valid ones were collected, with a response rate of 95.6%. The test of homogeneity in the item analysis showed that the correlation coefficient between each item and the total score of the scale was 0.40-0.80. The results of the value-based decision-making method showed that the critical ratio of high-and low-scored groups was 6.08-28.01. The quality of all the items met the retention requirements so that the reliability and validity tests could be continued. Validity test found that I-CVI was 0.83-1.00, consistent S-CVI was 0.83, and mean S-CVI was 0.95. In structural validity analysis, the KMO value was 0.96, and the Chi-square value of Bartlett′s test of sphericity was 10755.76 ( P<0.01). A total of 9 common factors were extracted with the K1 criterion (eigen value>1), and the scree plot indicated 9 common factors with a cumulative variance contribution rate of 73.46%. Factor extraction and rotation showed that the load value of each item of the scale ranged from 0.589 to 0.874. The correlation coefficient of the optimized MANTIC scale and EQ-5D-Y was r= 0.55 ( P<0.01).Reliability test showed that the Cronbach alpha coefficient of the total scale and all dimensions was 0.96 and 0.77-0.98, and the Guttman split-half reliability coefficient was 0.76 and 0.73-0.98. Conclusion:The optimized MANTIC scale can attain good reliability, validity, consistency and stability, and can reflect the concept to be expressed and the content to be evaluated, indicating that it can be used to evaluate the injury rehabilitation needs of injured children and their families throughout the entire treatment process.
RESUMO
As a common Tibetan medicine, Potentilla anserine L. is a kind of important Chinese materia medica, which is mainly distributed in Gansu, Qinghai and Tibet Provinces. As the active constituent from Potentilla anserine L., potentilla anserine polysaccharide has received initial research by researchers in abroad and at home. It is suggested that potentilla anserine polysaccharide exhibits various functions including antioxidation, anti-aging, immunoregulation, inhibiting bacteria and anti-diabetic. This article reviewed the research on extraction, purification and bioactivities of potentilla anserine polysaccharide, which is expected to provide ideas for the further study and research and development.
RESUMO
Pine pollen is a kind of Chinese materia medica with the homology of medicine and food, rich in a variety of nutrients and bioactive ingredients. It has the efficacy of hemostasis by convergence and eliminating dampness and astringing sores. Research showed that pine pollen is able to protect certain organs, regulate metabolism, enhance immunity and resist antioxidation and aging. This article reviewed pine pollen related research from the aspects of main components, pharmacological effects and clinical application, in order to provide references for further study and development and utilization.
