OBJECTIVE To investigate the mechanisms of paeoniflorin （PF） in anti-hyperprolactinemia （HPRL）. METHODS Twenty-four female SD rats were divided into blank control group （intragastric administration of 5% gum arabic solution）， olanzapine group （model group， intragastric administration of 5 mg/kg olanzapine suspension）， and PF group （intragastric administration of 5 mg/kg olanzapine suspension， followed by gavaging with 50 mg/kg PF solution 2 hours later） with 8 rats in each group. Once a day， continuously model/administer until the plasma prolactin （PRL） levels in the olanzapine group were twice as high as those in the blank control group. PRL levels were measured. The changes in gut microbiota of rats were analyzed， including assessments of α-diversity （Simpson， Chao1， and Shannon indexes）， β-diversity， species composition analysis （at the phylum and genus levels）， and microbiome LEfSe analysis. Fecal untargeted metabolomics technology was employed to analyze the effects of PF on the fecal metabolomics of rats， including multivariate statistical analysis， screening of differential metabolites， and pathway enrichment analysis. Spearman correlation analysis was performed to examine the correlations between differential microbiota and differential fecal metabolites. RESULTS PF significantly reduced serum PRL levels of rats in olanzapine group （P＜0.05）. 16S rRNA sequencing revealed that PF improved the α-diversity and β-diversity of gut microbiota in HPRL rats （P＜0.05）， restoring them to levels similar to the blank control group. At the phylum level， PF significantly reduced the relative abundance of Firmicutes and Desulfobacterota， while increasing the relative abundance of Verrucomicrobiota in HPRL rats （all P＜0.05）. At the genus level， PF reversed the relative abundance of Desulfovibrio，Allobaculum， and Prevotellaceae_NK3B31_group， etc （all P＜0.05）. The results of LEfSe analysis revealed that PF significantly enriched microbial taxa such as Actinobacteriota，Staphylococcales， Corynebacteriales， etc （all P＜0.05）. Metabolomics analysis identified 51 differential metabolites， with key metabolic pathways enriched in steroid hormone biosynthesis， prostate cancer， ovarian steroidogenesis， etc. Correlation analysis showed that the relative abundance of gut microbiota such as Desulfovibrio and Aerococcus was significantly correlated with the levels of steroid hormone metabolites such as tetrahydrocortisol and adrenosterone （P＜0.05）. CONCLUSIONS PF alleviates PRL by modulating gut microbiota structure in HPRL rats （including significantly reducing the relative abundance of Desulfovibrio， Allobaculum and Aerococcus， as well as significantly increasing the relative abundance of Ruminococcaceae_UBA1819 and Muribaculum）， and regulating steroid hormone pathways， then exerting its anti-HPRL effect.

Objective: To retrospectively analyze the clinical data of 474 newborns with hyperbilirubinemia, and to investigate the clinical characteristics of hyperbilirubinemia caused by ABO hemolytic disease of the fetus and newborn (ABO-HDFN) and factors influencing the phototherapy duration. Methods: A total of 474 neonates with hyperbilirubinemia treated in the First Hospital of Lanzhou University from January 2019 to January 2023 were enrolled. Blood type identification and the standard serological tests (direct antiglobulin test, serum free antibody test, and antibody elution test) were performed for all neonates. Baseline clinical data were collected and analyzed. According to the results of the hemolysis tests, neonates were divided into hemolytic jaundice group and non-hemolytic jaundice group. Clinical indicators, including hemoglobin levels, length of hospital stay, and phototherapy duration, were compared between the two groups. A multiple linear regression model was used to explore clinical factors influencing the duration of phototherapy. Results: Among the 474 neonates with hyperbilirubinemia, 354 were diagnosed with ABO-HDFN (hemolytic group), while 120 were without ABO-HDFN (non-hemolytic group). The incidence of ABO-HDFN in neonates with blood type A (55.93%, 198/354) was significantly higher than those with blood type B (44.07%, 156/354) (P<0.05). Furthermore, neonates born to multiparous women had a significantly higher ABO-HDFN incidence (81.56%, 146/179) than first-born neonates (70.51%, 208/295) (P<0.05). Neonates in the hemolytic group had significantly lower hemoglobin levels (170.67±21.86 g/L vs 178.99±22.05 g/L, P<0.001), lower red blood cell counts (4.66±0.63×10 /L vs 4.89±0.59×10 /L, P<0.05), and lower hematocrit (50.05±6.56% vs 52.61±6.75%, P<0.05) compared to the non-hemolytic group. Additionally, the hemolytic group had significantly longer hospital stays (6 [5, 9] days vs 6 [4, 8] days), longer phototherapy duration (62 [38, 84.25] h vs 53 [34.25, 64.77] h), and higher frequency of jaundice episodes (9 [7, 13] times vs 8 [6, 12] times] compared to the non-hemolytic group (all P<0.05). Regression analysis indicated that a positive indirect Coombs test and multiparity were independent risk factors associated with prolonged phototherapy duration (P<0.05). Conclusion: ABO incompatibility is the leading cause of hemolytic disease in neonates, particularly in cases where the mother has blood type O and the neonate has blood type A. In such cases, close monitoring of bilirubin levels is strongly recommended. Multiparous pregnancies increase the risk of alloimmune hemolysis. Therefore, neonates born to multiparous women may require more frequent bilirubin monitoring and appropriate prenatal interventions when necessary. Additionally, changes in indicators such as hemoglobin level and red blood cell count should be closely monitored as early warning indicators for hemolytic anemia and bilirubin elevation.
