BACKGROUND:The granulosa cell state greatly affects the quality of oocytes.As the increased proportion of aged women in assisted reproduction,granulosa cells from patients of different ages are examined at transcript levels in order to better assess oocyte quality. OBJECTIVE:To investigate the expression changes of mRNA and long non-coding RNA in granulosa cells from the young and aged patients. METHODS:Waste cumulus granulosa cells obtained during the assisted reproductive cycle.Young group was in 25-35 years old,and the aged group was in 38-45 years old.Granulosa cells collected from the young and aged females were analyzed using RNA sequencing,three replications for each group. RESULTS AND CONCLUSION:(1)The RNA sequencing analysis results showed that the average sequencing volume of samples was more than 14 G;the data quality Q30 after quality control was more than 93%;the average mapping rate of data was 98.4%,which indicates that the data had good quality.(2)The results of principal component analysis and correlation analysis showed that the samples of the aged group and the young group could be clearly distinguished.(3)The difference analysis results showed that compared with the young group,a total of 410 differentially expressed mRNAs were detected in the aged group(167 up-regulated and 243 down-regulated).GO analysis results showed that the down-regulated genes were mainly enriched in regulatedexocytosis and the emetabolicprocess.GSEA analysis results showed that secretion-related pathways in the aged group were down-regulated.(4)Compared with the young group,662 differentially expressed long non-coding RNAs were detected in the aged group,and 1 772 protein-coding genes were directly regulated by these long non-coding RNAs,among which 59 genes overlaped with differentially expressed genes.The results showed that the expression of secretion-related genes and pathways in granulosa cells of the aged group was down-regulated,thus affecting oocyte quality.At the same time,these down-regulated genes were regulated by long non-coding RNA.Therefore,the expression of long non-coding RNA might be related to age.

Receptor-interacting serine/threonine-protein kinase 1 (RIPK1) functions as a key regulator in inflammation and cell death and is involved in mediating a variety of inflammatory or degenerative diseases. A number of allosteric RIPK1 inhibitors (RIPK1i) have been developed, and some of them have already advanced into clinical evaluation. Recently, selective RIPK1i that interact with both the allosteric pocket and the ATP-binding site of RIPK1 have started to emerge. Here, we report the rational development of a new series of type-II RIPK1i based on the rediscovery of a reported but mechanistically atypical RIPK3i. We also describe the structure-guided lead optimization of a potent, selective, and orally bioavailable RIPK1i, 62, which exhibits extraordinary efficacies in mouse models of acute or chronic inflammatory diseases. Collectively, 62 provides a useful tool for evaluating RIPK1 in animal disease models and a promising lead for further drug development.

At present,the quality and safety management of multiple districts of hospital still has problems such as low informatization level,inconsistent quality and safety management mode,and insufficient quality and safety management concept.It takes an orthopedic hospital of Traditional Chinese Medicine as an example to explore the quality and safety management practice of multiple districts of hospital under the homogenization strategy.A three-level quality control management system composed of leadership,executive level and guidance level was constructed,and the general framework of the integrated quality management system and the specific work contents of quality management in each hospital were proposed,in order to provide a standardized and operable management mode for medical institutions to carry out medical quality management.
