ObjectiveTo investigate the effects of Astragali Radix polysaccharides (APS) on the polarization of BV2 microglial cells in an oxygen-glucose deprivation/reoxygenation (OGD/R) model through regulation of the Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) signaling pathway. MethodsThe OGD/R injury model of BV2 microglia was established and divided into blank group, OGD/R group and APS group (0.4 g·L-1 APS). Neuroinflammatory injury was induced by lipopolysaccharide (LPS) and treated with APS. The cells were divided into blank group, LPS group (1 mg·L-1 LPS) and APS group (0.4 g·L-1 APS+1 mg·L-1 LPS). Cell viability was detected using the cell counting kit-8 (CCK-8) assay. Cell morphology was observed under an inverted microscope. Nitric oxide (NO) content in the cell supernatant was determined by the Griess assay. The secretion levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-6, IL-10, and IL-4 were measured by enzyme-linked immunosorbent assay (ELISA). Immunofluorescence (IF) was used to detect the double-positive rates of ionized calcium-binding adapter molecule-1/inducible nitric oxide synthase (Iba-1+/iNOS+) and ionized calcium-binding adapter molecule-1/arginase 1 (Iba-1+/Arg1+), as well as the nuclear translocation rate of nuclear factor-κB p65 (NF-κB p65). Protein expression levels of Iba-1, iNOS, Arg1, TLR4, and NF-κB p65 were detected by Western blot. ResultsIn the OGD/R injury model, compared with the blank control group, BV2 microglial cells in the OGD/R group were activated and exhibited amoeboid morphological changes. The secretion levels of NO, TNF-α, and IL-6 were significantly increased (P<0.01). The double-positive expression rate of Iba-1+/iNOS+ and the protein expression of Iba-1 and iNOS were significantly increased (P<0.01). The nuclear translocation rate of NF-κB p65 and the protein expression levels of TLR4 and NF-κB p65 were significantly increased (P<0.01). The levels of IL-10 and IL-4 were significantly decreased (P<0.01), and the double-positive expression rate of Iba-1+/Arg1+ and Arg1 protein expression were significantly decreased (P<0.01). Compared with the OGD/R group, the APS group (0.4 g·L-1) showed reduced cell activation, significantly decreased secretion levels of NO, TNF-α, and IL-6 (P<0.01), significantly decreased double-positive expression rate of Iba-1+/iNOS+ and relative protein expression of Iba-1 and iNOS (P<0.01), significantly decreased nuclear translocation rate of NF-κB p65 and protein expression levels of TLR4 and NF-κB p65 (P<0.01), significantly increased levels of IL-10 and IL-4 (P<0.01), and significantly increased double-positive expression rate of Iba-1+/Arg1+ and Arg1 protein expression (P<0.01). In the LPS-induced neuroinflammation model, compared with the blank control group, the LPS group showed increased cell activation, significantly increased levels of NO, TNF-α, and IL-6, significantly increased Iba-1+/iNOS+ double-positive expression rate, NF-κB p65 nuclear translocation rate, and protein expression levels of Iba-1, iNOS, TLR4, and NF-κB p65 (P<0.01), while IL-10 and IL-4 levels, Iba-1+/Arg1+ double-positive expression rate, and Arg1 protein expression were significantly decreased (P<0.01). Compared with the LPS group, the APS group showed reduced cell activation, significantly decreased levels of NO, TNF-α, and IL-6, Iba-1+/iNOS+ double-positive expression rate, NF-κB p65 nuclear translocation rate, and protein expression levels of Iba-1, iNOS, TLR4, and NF-κB p65 (P<0.01), while IL-10 and IL-4 levels, Iba-1+/Arg1+ double-positive expression rate, and Arg1 protein expression were significantly increased (P<0.01). ConclusionAPS may reduce microglial activation and promote their polarization toward the M2 phenotype by inhibiting activation of the TLR4/NF-κB signaling pathway, thereby alleviating the neuroinflammatory response induced by OGD/R.

Diabetes mellitus (DM) is a major metabolic disease endangering global health, with diabetic nephropathy (DN) as a primary complication lacking curative therapy. Sporoderm-broken spores of Ganoderma lucidum (GLP), an herbal medicine, has been used for the treatment of metabolic disorders. In this study, DN was induced in Sprague-Dawley rats using streptozotocin (STZ) and a high-fat diet (HFD), and the protective mechanisms of GLP were investigated through transcriptomic, metabolomic, and network pharmacology (NP) analyses. Our results demonstrated that GLP intervention ameliorated renal damage and inflammation levels in DN rats. Integrative metabolomic and transcriptomic analysis revealed that GLP treatment modulated glucose and cellular energy metabolisms by regulating relevant genes. GLP significantly suppressed the inflammations by impacting glucose and energy metabolism-related gene expression (Igfbp1 and Angptl4) and enhanced metabolic biomarkers of 4-Aminocatechol. In addition, NP analysis further indicated that GLP may efficiently alleviate DN via immune-related pathways. In conclusion, this study provides supportive evidence of the anti-inflammatory effects of GLP supplements, highlighting their potential for promising clinical applications in treating DN.

Objective:To identify the anatomical landmarks with stable and consistent performance in both rigid and deformation registrations,and to investigate the feasibility that take them as the quantitative indexes for quantitative evaluation of multimodality image registration for pancreatic cancer in clinical practice. Methods:Twenty-five patients with pancreatic cancer were selected.Both the rigid and deformation registrations were performed between simulated CT and MRI T1-weighted images.Seven anatomical landmarks,which were left adrenal gland,portal vein,celiac trunk artery,superior mesenteric artery,lumbar vertebral body,inferior vena cava and abdominal aorta,were selected.The anatomical landmarks were marked on the simulated CT and the registered MRI,respectively.The distances between the geometric centers of each anatomical landmarks in two kinds of images were statistically analyzed.The Wilcoxon rank sum test was implemented to compare the differences between rigid and deformation registrations.In addition,the correlations between anatomical landmarks were analyzed as well. Results:The mean distances of centers for the seven anatomical markers under rigid registration ranged from 0.405 cm to 1.097 cm,while they ranged from 0.433 cm to 0.740 cm under deformation registration.There was no significant difference in the registration of anatomical markers between rigid and deformation registration,except the left adrenal gland.The registration differences of celiac trunk artery and abdominal aorta were of most stable in 25 patients.Correlation study showed that all anatomical markers except abdominal aorta and inferior vena cava were independent and significant. Conclusion:It is feasible to quantitatively evaluate the registration quality of multimodality image registration for pancreatic cancer by using anatomical landmarks.It is recommended to use celiac trunk artery and abdominal aorta as the anatomical markers in clinical procedure.They are both stable in rigid and deformation registration,and the correlation between them is low,with means they can be used as independent evaluation criteria.
