Objective: To evaluate the application of blood conservation measures in obstetric patients with different red blood cell transfusion volumes and to assess the impact of different transfusion volumes on postpartum outcomes. Methods: A retrospective investigation was conducted on 448 obstetric patients who received blood transfusions at the Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to December 2022. Patients were divided into four groups (1-2 units group, 3-4 units group, 5-6 units group, and >6 units group) based on the volumes of red blood cells (RBCs) transfused during and within 7 days after delivery. The maternal physiological indicators, pre- and postpartum laboratory test indicators, obstetric complications, application of blood conservation measures, use of blood products, and postpartum outcomes were reviewed. The clinical characteristics, application of blood conservation measures, and their impact on postpartum outcomes were compared among different transfusion groups. Results: There were statistically significant differences in the multivariate logistic analysis of history of previous cesarean section (OR=1.781), eclampsia/pre-eclampsia/(OR=1.972) and postpartum blood loss>1 000 mL（OR=1.699）(P<0.05) among different transfusion groups. In terms of blood conservation measures, the more RBCs transfused, the higher the rate of mothers receiving blood conservation measures such as balloon occlusion, arterial ligation, autologous blood transfusion with a cell saver, and hysterectomy. With the increase in the volume of RBCs transfusion, the demand for fresh frozen plasma（FFP）, cryoprecipitate, and platelet transfusions also increased. The hospitalization days for the four groups of parturients were 6.0 (4.0-9.0), 7.5 (5.0-14.8), 7.0 (4.5-13.0) and 11.0 (9.0-20.5), respectively (P<0.05) and the rates of ICU transfer were 2.0% (5/250), 9.4% (12/128),18.2% (6/33) and 51.4% (19/37), respectively (P<0.05). Both increased significantly with the increase in the volume of RBCs transfusion, and the differences between groups were statistically significant. Conclusion: Parturients who received higher volume of RBCs had multiple risks factors for bleeding before childbirth, had higher postpartum blood loss, and had a higher rate of application of various blood conservation measures. In addition, an increase in the volume of RBCs transfusion may have adverse effects on postpartum recovery.

Depression is a widespread psychiatric disorder with complex pathogenesis and unsatisfactory therapeutic effects. As a native flavonoid, Isorhamnetin (ISO) has been deemed to exert neuroprotective effects by antioxidation and regulation of immunity. However, no reports of anti-depressed effect of ISO have yet been found. The present study was conducted to clarify the mechanism basis of anti-depressed effect of ISO utilizing behavioral, biochemical, molecular approaches in vitro and in vivo and bio-informatics analysis. The effects of ISO on depressed mice was investigated through the SPT and FST, and the lesions were examined by H&E staining. Besides, the inflammatory factor and indicator in kynurenine pathway were assessed through detection kits, and the microbiota were checked by 16sRNA. Molecular docking study was performed to investigate the target of ISO. Additionally, Western blot was used to test the activation of PI3K/AKT signaling pathway. The results indicated that ISO could enhance the sugar water preference of mice in SPT and reduce immobility time in FST. Further more, ISO suppressed peripheral and central inflammation, regulated the changes in kynurenine pathway and gut microbiota, inhibited activation of PI3K/AKT pathway, and presented good binding patterns with target proteins on PI3K/AKT signaling pathway. Collectively, these findings demonstrate that ISO alleviated depression-like behaviour by normalizing inflammation-induced dysregulation of the crosstalk between KP and gut microbiota disorder through regulated PI3K/AKT/NF-κB pathway.

BACKGROUND:In clinical practice,Cibotium barometz and Epimedium have shown significant efficacy in the treatment of rheumatoid arthritis,but the complex active ingredients contained in the two have an unclear mechanism of action at the molecular level for the treatment of rheumatoid arthritis. OBJECTIVE:Based on network pharmacology and molecular docking technology,to establish a collagen-induced arthritis model and to verify the potential targets and pathways of Cibotium barometz and Epimedium in the treatment of rheumatoid arthritis,providing reliable experimental evidence for the use of clinical formulas with Cibotium barometz and Epimedium as the main components. METHODS:Utilizing traditional Chinese medicine research platforms,traditional Chinese medicine encyclopedias,and databases of traditional Chinese medicine and chemical components from the Shanghai Institute of Organic,effective ingredients were retrieved and identified.3D molecular formulas were obtained from the PubChem platform and target predictions were made using PharmMapper and SwissTargetPrediction.Disease targets for rheumatoid arthritis were obtained from gene databases such as DrugBank,GeneCards,and OMIM.The intersections of targets and Cibotium barometz and Epimedium were plotted using VENNY 2.1 after calibration with the Uniport database.A protein-protein interaction network graph was constructed using the STRING platform.Gene Ontology function analysis and Kyoto Encyclopedia of Genes and Genomes enrichment analysis were performed using the Metascape platform for data visualization.A four-layered network model of traditional Chinese medicine,ingredients,targets,diseases,and pathways was constructed using Cytoscape 3.9.0.The main effective ingredients were docked with core targets using AutoDock-Vina software to explore the best binding targets.A type II collagen+adjuvant-induced arthritis rat model was established,and the effects of Cibotium barometz and Epimedium on relevant pathway targets and inflammatory cell factors were observed after 21 days of intervention. RESULTS AND CONCLUSION:A total of 28 active ingredients from Cibotium barometz and Epimedium were selected,yielding 288 intersection targets for rheumatoid arthritis.The main ingredients included isobavachalcone,cibotium,and epimedium.The main targets included protein kinase 1 for serine/threonine(AKT1),tumor necrosis factor,and vascular endothelial growth factor A.Gene ontology analysis yielded 2 232 biological processes,mainly related to serine protein phosphorylation,positive regulation of serine/threonine protein kinase,and reactive oxygen metabolism.Kyoto Encyclopedia of Genes and Genomes enrichment analysis yielded 202 pathways,mainly involving the PI3K/AKT signaling pathway and epidermal growth factor receptor signaling pathway,which may exert therapeutic effects by regulating synovial cell apoptosis and proliferation and suppressing inflammatory factors.Molecular docking results showed the strongest binding activity and stable structure of Cibotium barometz and Epimedium with AKT1 and estrogen receptor transcription factor 1,which was closely related to apoptosis and proliferation and inflammatory signaling pathways such as PI3K/AKT.Cibotium barometz and Epimedium reduced the expression of interleukin-1β,interleukin-6,and tumor necrosis factor-α in the serum of collagen-induced arthritis rat models.Cibotium barometz and Epimedium reduced the expression of p-PI3K,p-AKT,and p-FOXO1 in the synovium of collagen-induced arthritis rat models.The results indicate that the combination of Cibotium barometz and Epimedium may exert therapeutic effects by inhibiting the proliferation of synovial cells and suppressing the expression of inflammatory factors via the PI3K/AKT/FOXO1 signaling pathway.This may be closely related to the occurrence of inflammation and bone destruction in rheumatoid arthritis,and provides a reference for the rational use and development of new drugs in clinical practice.

Objective: To explore the relationship between the ratio of dietary vitamin A (VitA) to body weight and hypertension among children, so as to provide a reference for blood pressure control through dietary nutritional interventions and childhood hypertension prevention. Methods: Utilizing the baseline survey and followup sample data from the Healthy Children Cohort established in urban and rural areas of Chongqing from 2014 to 2019, structured quantitative dietary questionnaire and selfdesigned questionnaire were used to investigate the information of dietary intake and socioeconomic characteristics of 15 279 children, as well as blood pressure, height, weight measurement. The ratio of dietary VitA to body weight was divided into four groups based on quartiles [≤P25(Q1), >P25~P50(Q2), >P50~P75(Q3), >P75(Q4)]. Generalized linear regression models and Logistic regression models were used to analyze the correlation between ratio of dietary VitA to body weight with blood pressure levels and prevalence of hypertension. Results: The results of the 2014 baseline survey indicated that, after adjusting for confounding factors such as demographic indicators and nutritional intake, significant differences were observed in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) among different groups categorized by the ratio of dietary VitA to body weight (F=157.57, 44.71, 95.92, P<0.01). The baseline ratio of dietary VitA to body weight in children exhibited a negative correlation with DBP, SBP and MAP at baseline and in 2019[baseline: β(95%CI)=-0.65(-0.89--0.42), -0.22(-0.42--0.01), -0.36(-0.56--0.16); 2019: β(95%CI)=-0.77(-1.34--0.19), -0.62(-1.21--0.02), -0.77(-1.34--0.19), P＜0.05]. Compared to Q1 group, the risk of hypertension decreased among children in Q4 at baseline and followup in 2019 [OR(95%CI)=0.63(0.49-0.81), 0.18(0.08-0.42), P<0.01]. Conclusions The ratio of dietary VitA to body weight is significantly negatively correlated with blood pressure levels among children, and dietary VitA deficiency is an independent risk factor for hypertension among children. Measures should be taken to actively adjust childrens dietary nutrition and reduce the risk of childhood hypertension.

Hepatocellular carcinoma (HCC) is one of the most common malignancies and is a major cause of cancer-related mortalities worldwide (Forner et al., 2018; He et al., 2023). Sarcopenia is a syndrome characterized by an accelerated loss of skeletal muscle (SM) mass that may be age-related or the result of malnutrition in cancer patients (Cruz-Jentoft and Sayer, 2019). Preoperative sarcopenia in HCC patients treated with hepatectomy or liver transplantation is an independent risk factor for poor survival (Voron et al., 2015; van Vugt et al., 2016). Previous studies have used various criteria to define sarcopenia, including muscle area and density. However, the lack of standardized diagnostic methods for sarcopenia limits their clinical use. In 2018, the European Working Group on Sarcopenia in Older People (EWGSOP) renewed a consensus on the definition of sarcopenia: low muscle strength, loss of muscle quantity, and poor physical performance (Cruz-Jentoft et al., 2019). Radiological imaging-based measurement of muscle quantity or mass is most commonly used to evaluate the degree of sarcopenia. The gold standard is to measure the SM and/or psoas muscle (PM) area using abdominal computed tomography (CT) at the third lumbar vertebra (L3), as it is linearly correlated to whole-body SM mass (van Vugt et al., 2016). According to a "North American Expert Opinion Statement on Sarcopenia," SM index (SMI) is the preferred measure of sarcopenia (Carey et al., 2019). The variability between morphometric muscle indexes revealed that they have different clinical relevance and are generally not applicable to broader populations (Esser et al., 2019).
