Traditional research ideas of miRNA-target gene-biological function have ignored the contact between the target genes and signaling pathways involved , making the integrity and relevance of miRNA regulatory mechanisms not be fully elucidated .Integrated with systematic and relevant way of thinking , summarization and analysis for the luciferase reporter assay validated miR-205 target genes and their related signaling pathways will pave the way for new research area for miR-205 , and , it will be helpful for breaking through the status quo and exploring the novel research areas for miRNA .

Objective:To analyze the hospitalization costs of delivery for postpartum women with different delivery methods, ages and comorbidities or complications, for references for medical institutions and medical insurance management departments to develop payment and compensation standards for inpatient delivery.Methods:The first page of medical records of hospitalized delivery women admitted to 8 large tertiary hospitals in Beijing from January 2018 to December 2021 were selected. Descriptive analysis was made on the mode of delivery, age, hospitalization expenses and cost structure of puerpera, as well as the hospitalization expenses of puerpera with different complications or complications. Wilcoxon rank sum test, Kruskal-Wallis H test, and Chi-squared test were used to statistically compare the level and structure differences between groups. Results:A total of 23 320 pregnant women were included, with an average age of 32.3 years. There were 13 605 cases of natural delivery and 9 715 cases of caesarean section. The median cesarean section rate in the right age group (<35 years old) and the elderly group (35-50 years old) were 36.73% and 56.58%, respectively, and the median hospital expenses were 5 865 yuan and 7 042 yuan, respectively. The median hospital expenses for natural delivery and caesarean section were 4 452 yuan and 10 033 yuan, respectively. The highest proportion of hospitalization expenses for natural delivery and cesarean section were treatment expenses (23.45%) and medicine expenses (29.19%), respectively. The median of hospitalization cost for women with≥2 comorbidities or complications (6 736 yuan) was higher than that for women with 1 comorbidities or complications (5 794 yuan).Conclusions:The hospitalization cost of cesarean section was significantly higher than that of natural delivery and the rate of cesarean section and the cost of delivery in women aged 35 and above were higher than those under 35 years old. The structure of hospitalization cost was different in different delivery modes, and the complications or complications had a greater impact on the average hospitalization expenses.
