Following blood collection, samples are prepared for flow cytometric analysis either unstimulated <t>(PBS</t> as buffer control) or stimulated with an inflammatory cocktail (cocktail of N-formylmethionyl-leucyl-phenylalanine, platelet-activating factor, and tumor necrosis factor). The CRC is calculated as the ratio of median fluorescence intensity (MFI) between stimulated and unstimulated neutrophils. Three approaches, classic, simple, and kinetic CRC, offer distinct advantages and limitations based on technical aspects such as manual processing steps (e.g., centrifugation) and incubation time. n =13–14. Statistical analysis was performed using the Kruskal-Wallis test with Dunn’s post-hoc test, comparing patients with sepsis at all time points (shown in the figure: 0 h, not shown in the figure: 24, 72, 120 h) with healthy volunteers (HV).

Blood from healthy volunteers was incubated with either PBS (Control) or 100 ng/ml LPS for 60 min in the ex vivo whole blood model. a Analysis of the median fluorescence intensity (MFI). b Evaluation of the CRC as determined by different approaches (classic, simple, and kinetic CRC). c, d Change in fluorescence intensity and change in CRC using the kinetic CRC approach, comparing blood with previous exposure to LPS or PBS (buffer control) from the ex vivo whole blood model. In both c and d , the single-cell values measured by flow cytometry were condensed using a moving median with a window of 9 cells. This moving median was then approximated with a 5 th -degree polynomial function. The plots display these polynomial functions together with the baseline (median before stimulation) and a connecting line from the baseline to the polynomial function for 30 s after stimulation. Values are shown as median and interquartile range. n= 10. Statistical analysis was performed using the Mann-Whitney U test. ⁎⁎⁎ P <0.001. AU. Arbitrary units; LPS. Lipopolysaccharide; PBS.

While Phellodendri chinensis Cortex (PC) has shown renoprotective promise, the therapeutic value of its processed products remains unclear.. We therefore compared raw PC (RPC) with three processed derivatives—salt-processed PC (SPC), salt praeparatum-processed PC (SP-PC), and depositum urinae praeparatum-processed PC (DUP-PC)—to evaluate whether processing enhances anti-ferroptotic activity and DN protection.

The CRC is calculated as the ratio of median fluorescence intensity (MFI) between stimulated and unstimulated neutrophils. Three approaches, classic, simple, and kinetic CRC, offer distinct advantages and limitations based on technical aspects such as manual processing steps (e.g., centrifugation) and incubation time. n =13–14.
