ObjectiveTaking classical herbal pair compatibility research as the entry point, this study aimed to deeply investigate the material basis and compatibility rules underlying the antidepressant effects of the traditional Chinese medicine (TCM) formula Zhizi Houpotang, and to elucidate its antidepressant mechanism, with a particular focus on its regulation of neuroinflammatory responses mediated by the NOD-like receptor protein 3 (NLRP3)/gasdermin D (GSDMD) signaling pathway and the consequent improvement of neuronal synaptic plasticity. MethodsC57BL/6J mice were randomly divided into a blank control group, a chronic unpredictable mild stress (CUMS) depression model group, a Zhizi Houpotang full-formula group (6 g·kg-1·d-1), a Magnoliae Officinalis Cortex (MOC)-Aurantii Fructus Immaturus (AFI) herbal pair group (4.2 g·kg-1·d-1), a Gardeniae Fructus (GF)-MOC herbal pair group (4.2 g·kg-1·d-1), a GF-AFI herbal pair group (3.6 g·kg-1·d-1), and a positive drug group (fluoxetine, 12 mg·kg-1·d-1). Depressive-like behaviors in mice were evaluated using behavioral tests. Immunofluorescence staining was used to label and quantify the expression of the microglial marker ionized calcium-binding adaptor molecule 1 (Ibal) and the purinergic receptor P2X ligand-gated ion channel 7 (P2RX7) in the prefrontal cortex (PFC). Enzyme-linked immunosorbent assay (ELISA) was applied to detect the levels of inflammatory cytokines interleukin-1β (IL-1β) and interleukin-18 (IL-18) in serum and PFC tissues. Western blot was employed to determine the expression of pannexin 1 (Panx1), P2RX7, NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), Caspase-1, GSDMD, postsynaptic density protein 95 (PSD95), and the presynaptic protein Synapsin 1 in PFC tissues. Golgi staining was used to assess dendritic spine density of neurons in the PFC. ResultsCompared with the blank control group, the depression model group exhibited significant depressive-like behaviors. In addition, the immunofluorescence areas of Ibal and P2RX7 in the PFC were significantly increased (P<0.01), the levels of IL-1β and IL-18 in serum and the PFC were significantly elevated (P<0.01), and the protein expression levels of Panx1, P2RX7, NLRP3, ASC, Caspase-1, and GSDMD in the PFC were significantly upregulated (P<0.01). In contrast, the protein expression levels of PSD95 and Synapsin 1 were significantly downregulated (P<0.01), and neuronal dendritic spine density was significantly reduced (P<0.01). Compared with the model group, the Zhizi Houpotang full-formula group and the GF-MOC herbal pair group showed significant improvement in all the above indicators (P<0.01). The GF-AFI herbal pair group improved all the above indicators except P2RX7, Caspase-1, GSDMD, and PSD95 (P<0.05, P<0.01). In contrast, the MOC-AFI herbal pair group showed no statistically significant improvement in any of the above indicators compared with the model group. ConclusionZhizi Houpotang and its key herbal pair, GF-MOC, can effectively ameliorate CUMS-induced depressive-like behaviors in mice. Its core antidepressant mechanism may involve inhibition of P2RX7/Panx1 signaling, thereby blocking the NLRP3/GSDMD-mediated pyroptosis pathway and significantly reducing the release of inflammatory cytokines IL-1β and IL-18. Simultaneously, it upregulates the expression of synapse-related proteins PSD95 and Synapsin 1 and increases dendritic spine density, promoting the recovery of synaptic plasticity. These results suggest that GF plays a key role in the antidepressant effects of this formula, and that the compatibility of GF with MOC may represent the principal herbal pair combination responsible for its core therapeutic action.

Interferon regulatory factor 4 (IRF4) is a critical transcription factor that governs the differentiation of cluster of differentiation 4+ (CD4+) T cells. The pathogenesis and progression of psoriasis are primarily attributed to an immune imbalance stemming from the overproduction of interleukin-17A (IL-17A) by T lymphocytes. However, the role of IRF4 in psoriasis remains unexplored. In this study, we found that IRF4 activity is increased in the cutaneous lesions of patients with psoriasis in response to stimulation by IL-23A and IL-1β. This IRF4 elevation heightens its binding to the E1A binding protein p300 (EP300) promoter, triggering the transcription of downstream retinoic acid receptor-related orphan receptor-γt (RORγt) and increasing the secretion of IL-17A, thereby establishing the IL-1β/IL-23A-IRF4-EP300-RORC-IL-17A inflammatory cascade in psoriasis. The alleviation of imiquimod (IMQ)-induced psoriatic-like symptoms was achieved through the creation of a Irf4 -/- gene deletion mouse model and pharmacological inhibition using antisense oligonucleotides targeted for Irf4. This amelioration was accompanied by a decreased number of IL-17A-producing CD4+ T cells in the skin. The findings of this study suggest that IRF4 plays a crucial role in the promotion of inflammation and exacerbation of IMQ-induced psoriasiform dermatitis. Consequently, IRF4 targeting could be a promising therapeutic strategy.

Objective:To explore the association between the systemic immune-inflammation index (SII) and obesity metabolic phenotypes, as well as metabolic features in children and adolescents.Methods:A cross-sectional study was conducted using the random cluster sampling method from March 2023 to May 2024. Children and adolescents aged 9-17 years in Guangzhou were surveyed through questionnaires, physical measurements, and blood tests. According to BMI and metabolic status, participants were classified into normal-weight groups [metabolically healthy normal weight (MHNW) and metabolically unhealthy normal weight (MUNW)] and overweight/obese groups [metabolically healthy overweight/obese (MHO/O) and metabolically unhealthy overweight/obese (MUO/O)]. After natural log-transformation of SII values (lnSII), multinomial logistic regression was used to assess the association between SII and obesity metabolic phenotypes, while binary logistic regression was applied to assess the relationship between SII and metabolic phenotypes in the overweight/obese subgroup. Linear regression model and restricted cubic spline (RCS) were employed to examine the relationship between SII and metabolic features among the entire population.Results:A total of 3 749 participants were included. After adjusting for covariates, for every unit increase in lnSII, the risk of MHO/O and MUO/O increased by 93% ( OR=1.93, 95% CI: 1.56-2.40, P<0.001) and 156% ( OR=2.56, 95% CI: 2.02-3.25, P<0.001), respectively. In the overweight/obesity subgroup, for every unit increase in lnSII, the risk of MUO/O increased by 37% ( OR=1.37, 95% CI: 1.01-1.87, P=0.045). Linear regression model and RCS showed that lnSII was positively correlated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) (SBP: β=1.39, 95% CI: 0.67-2.11, P<0.001; DBP: β=1.27, 95% CI: 0.79-1.75, P<0.001). lnSII also had a non-linear relationship with triglyceride ( Pnonlinear=0.032) and high-density lipoprotein cholesterol ( Pnonlinear=0.002). Conclusion:Elevated SII levels are associated with unfavorable obesity metabolic phenotypes, higher blood pressure, and altered lipid profiles in children and adolescents. SII may be a potential driving factor for metabolic heterogeneity in children and adolescents.
