2.Association of adiponectin receptor 1(Adipo R1)gene polymorphism with type 2 diabetes
Chinese Journal of Diabetes 2008;16(7):394-396
Objective To study the association of SNP of the AdipoR1 gene with T2DM in Xi’an population. Methods The amplification refractory mutation system(ARMS) analysis and gene sequencing were used to investigate the AdipoR1 gene polymorphism in 100 type 2 diabetics and 84 normal control subjects. Results (1) The genotype and allele frequencies of -106A/G, 5843A/G were not significantly different between type 2 diabetics and normal control subjects. (2) The diagnosis age of diabetics was significantly younger in AdipoR1 5843GG genotype group than in other genotype groups. Conclusions The data implicate that the AdipoR1 gene -106A/G and 5843A/G polymorphism may be not associated with pathogenesis of T2DM. AdipoR1 5843 GG genotype may be associated with the earlier diagnosis of T2DM
3.Comparative study of the different methods of small RNA high-throughput sequencing library preparation in human brain tissues
Chinese Journal of Geriatrics 2017;36(6):692-696
Objective The aim of this study is to investigate the effects of the initial amount of total RNA input,adapter dilution and PCR amplification cycles on the results of small RNA library preparation and high-throughput sequencing.Methods Based on the sequencing reads number,the number of detected miRNAs and the accuracy of quantitative detection,we explored the effects of initial Total RNA,dilution ratio and PCR cycles on the quality of microRNA library preparation and high-throughput sequencing,respectively.Results For libraries preparation of the normal RNA input(1 μg),the adapter dilution combined with 22 PCR cycles could gain the best quality of sequencing.In the low-input libraries(10 ng),adapter dilution and increased PCR cycles would also improve the quality of sequencing,but as compared with the 1 μg library,there was lower correlation with microarray quantitative results in general.Conclusions The initial amount of RNAs input has the biggest effects on the quality of sequencing,and the quantity accuracy rate of low-input libraries is lower than the normal libraries generally.Increasing the PCR amplification cycles properly is indispensable to low-input libraries.

6.The characteristics and treatment of rare embryonal tumors of central nervous system in children
Chinese Journal of Applied Clinical Pediatrics 2021;36(3):168-171
Embryonal tumors of central nervous system (CNS) are highly invasive malignant tumors that mainly affect infants.Even if the current active treatment strategies are given, the prognosis is still very poor.The 2016 World Health Organization(WHO) classification integrates the genetic information of diseases with histopathology, so as to make the classification and diagnosis of these tumors more accurate.In the new classification, embryonal tumors of CNS include the most common medulloblastoma, and the rare embryonal tumor with multilayered rosettes, C19MC-altered, embryonal tumor with multilayered rosettes, not otherwise specified (NOS), medulloepithelioma, CNS neuroblastoma, CNS ganglioneuroblastoma, CNS embryonal tumor, NOS, atypical teratoid rhabdoid tumor, and CNS embryonal tumor with rhabdoid features.Further study and exploration on the biological nature of these rare brain tumors will provide scientific basis for new treatment methods.

Quality of life(QOL) is a broad-ranging concept,incorporating in a complex way the person's physical health,psychological state,social relationships,and has been widely used as health outcomes.But in postnatal research or health care in China,the application of QOL was restricted due to the deficiency of assessment tool.Quality of life scale includes two categories: general scale(designed for general population) and specific scale(designed for specific population).General scale didn't cover the specific issues introduced by childbirth.Specific scale for postnatal women was lacking until Symon designed an open Mother-Generated Index(MGI).But the MGI had a high requirement for the understanding ability of audiences,and the completion was easily influenced by environment,both restricted the utilization in China.A specific,valid and reliable postnatal QOL scale is needed to develop in China.The aim of this overview is to describe the traits of the postnatal women's health,the meaning of the application of QOL in this period,and the situation analysis of the application in China.

Objective:To select items to compose the final scale from 101-item pool for assessment of postnatal quality of life which was developed by the authors before. Methods: Ten experts in maternal and child health scored the importance of every item. A total of 200 women at 0-12 months after childbirth who took their babies for vaccination or clinic services were investigated by the item pool, and 10% of them were retested in one month. Based on these data, items in the item pool were screened by following principles respectively: score of item importance, factor loading, variation coefficient, Cronbach Alpha, correlation coefficient of item with domains (2 types) and test-retest correlation coefficient. Then we summarized the screening results of these methods, and retained the items which could be selected in at least five methods. Results: The numbers of items deleted in these seven screening methods respectively were: 39 items in experts scoring method; 43 items in factor analysis method; 49 items in variation analysis method; 50 items in Cronbach Alpha method; 26 items in correlation coefficient method 1; 9 items in correlation coefficient method 2; and 11 items in test-retest method. After summarizing these screening results, 60 items were selected. In order to simplify the scale,only kept 2 items in each aspect which had more frequency retained. Finally, 40 items remained in the postnatal quality of life scale. Conclusion: This is the first Chinese scale for evaluating postnatal quality of life of women. It needs to establish the validity and reliability in the future.
