OBJECTIVE To explore the action mechanism of kushenol F （KSCF） in treating ulcerative colitis （UC） in mice. METHODS The potential targets of KSCF intervening in UC were predicted with network pharmacology and molecular docking. C57BL/6J mice were randomly divided by body weight into model group， positive control group （sulfasalazine， 703 mg/kg）， KSCF group （100 mg/kg）， and normal group， with 6 mice per group. The UC model of mice was induced by dextran sulfate sodium solution. During the modeling period， the mice were given relevant medicine intragastrically， once a day， for 7 consecutive days. After the last administration， the disease activity index （DAI） of the mice was scored； the length of the mice’s colon was measured； pathological changes in the colon tissue of mice were observed； the levels of lipopolysaccharide （LPS） in serum， myeloperoxidase （MPO）， nitric oxide （NO） and superoxide dismutase （SOD） in the colon were detected in mice； the expression levels of occludin and ZO-1 in colon tissue of mice were detected； the proportions of CD3+T， CD4+T， and CD8+T lymphocytes in the spleen and the ratio of CD4+/CD8+ were detected； changes in colonic microbiota were analyzed by 16S rDNA sequencing. RESULTS Results of network pharmacology indicated that KSCF may treat UC by regulating signaling pathways such as phosphatidylinositol-3 kinase/protein kinase B （PI3K/AKT） and nuclear factor kappa B （NF- κB）. Molecular docking results showed that KSCF bound most stably with NF-κB p65 protein. Animal experiment results demonstrated that， compared with the model group， the pathological characteristics of colon tissue in mice were improved in KSCF group. DAI scores， serum levels of LPS， the levels of MPO，NF-κB p65 phosphorylation and NLRP3 protein expression in the colon， and the proportion of CD8+T lymphocytes in the spleen were reduced significantly （P＜0.05）. Body weight， SOD levels， expression levels of occludin and ZO-1 in the colon， proportions of CD3+T and CD4+T lymphocytes， and the CD4+/CD8+ ratio in the spleen were significantly increased （P＜0.05）； the abundance of Firmicutes， Actinobacteria， Akkermansia， and Lactobacillus genera were increased， while Proteobacteria decreased； the microbial community structure tended towards that of the normal group. CONCLUSIONS KSCF alleviates UC by restoring intestinal microbial imbalance， enhancing immune response， and inhibiting colonic inflammatory responses， thereby improving intestinal barrier integrity.

OBJECTIVE To investigate the intervention effect of kushenol F （KSC-F） on ulcerative colitis （UC） mice. METHODS Totally 30 male C57BL/6J mice were randomly divided into the normal group， model group， positive drug group （sulfasalazine， 703 mg/kg）， KSC-F 50 mg/kg group （KSC-F50 group）， and KSC-F 100 mg/kg group （KSC-F100 group）， with 6 mice in each group. Except for the normal group， the mice in the remaining groups were given 3% dextran sulfate sodium solution continuously for 7 days to induce UC model. Concurrently， administration groups received corresponding drug solution intragastrically， once a day， for 10 consecutive days. During the experiment， the changes in body weight and bowel movements of the mice were observed. Disease activity index scoring was performed after the last administration. The histopathological morphology of colonic tissue was examined. The levels of inflammatory factors in the serum and colon tissue were measured. Additionally， the mRNA expression of inflammatory factors， and the protein expressions of inflammation-related proteins [interleukin-1β （IL-1β）， forkhead box O1（FOXO1）， phosphoinositide 3-kinase（PI3K）， phosphorylated PI3K（p-PI3K）， p38 mitogen-activated protein kinase（p38 MAPK）， phosphorylated p38 MAPK（p-p38 MPAK） and phosphorylated protein kinase B（p- Akt）] were determined in colonic tissue. RESULTS KSC-F could alleviate weight loss and colonic tissue damage in UC mice. KSC- F reduced the levels of IL-1β， IL-6， IL-8 and tumor necrosis factor-α （TNF-α） in serum， as well as IL-1β， IL-6， IL-17 and TNF- α in colonic tissue to varying degrees and increased the levels of IL-10 in both serum and colonic tissue （P＜0.05 or P＜0.01）. Moreover， KSC-F decreased the expression levels of IL-1β， IL-17 and TNF-α mRNA， as well as p-PI3K， p-p38 MAPK， and p- Akt proteins in colonic tissue to varying degrees， and increased the expression levels of IL-10 mRNA and FOXO1 protein in colonic tissue （P＜0.05 or P＜0.01）. CONCLUSIONS KSC-F effectively alleviates UC symptoms in mice by inhibiting PI3K， Akt and p38 MAPK activation， mitigating the release of pro-inflammatory factors such as IL-1β， IL-6， TNF- α，promoting the anti-inflammatory factor IL-10 secretion， and reducing inflammation-induced colonic tissue damage.

Compound formulas of traditional Chinese medicines （TCM）， also known as prescription in clinic， refers to a form of medication in which several TCMs are selectively combined according to the certain compatibility principles and the needs of patient’s condition， based on syndrome differentiation and treatment. At present， the methods and strategies for investigating the compatibility mechanisms of TCM prescriptions mainly focus on the following two aspects: analysis of pharmacological substances （including chemical composition analysis of TCM， ingredients of TCM analysis in blood， and pharmacokinetic analysis） and pharmacological signaling pathways analysis （involving network pharmacology analysis， signal pathway indicator detection， and metabolomics analysis）. In future research， the compatibility relationships of TCM prescriptions should be explored according to the principles of “Qiqing Hehe”，“ Shengjiang Fuchen”，“ Junchen Zuoshi”， and “Siqi Wuwei”. The regularity of TCM prescriptions compatibility should be shown in the change regularity of chemical components， pharmacokinetics， pharmacological pathways， and chemical compositions of various ratios of TCMs. Based on the insurance of holistic efficacy of TCM prescriptions， the underlying mechanisms of compatibility should be uncovered， which will provide references for the optimization of clinical applications of prescriptions and new directions for the creation of innovative TCM prescriptions.

Neurogenesis decline in hippocampal dentate gyrus (DG) participates in stress-induced depressive-like behaviors, but the underlying mechanism remains poorly understood. Here, we observed low-expression of NOD-like receptor family pyrin domain containing 6 (NLRP6) in hippocampus of stress-stimulated mice, being consistent with high corticosterone level. NLRP6 was found to be abundantly expressed in neural stem cells (NSCs) of DG. Both Nlrp6 knockout (Nlrp6^-/-) and NSC-conditional Nlrp6 knockout (Nlrp6CKO) mice were susceptible to stress, being more likely to develop depressive-like behaviors. Interestingly, NLRP6 was required for NSC proliferation in sustaining hippocampal neurogenesis and reinforcing stress resilience during growing up. Nlrp6 deficiency promoted esophageal cancer-related gene 4 (ECRG4) expression and caused mitochondrial dysfunction. Corticosterone as a stress factor significantly down-regulated NLRP6 expression, damaged mitochondrial function and suppressed cell proliferation in NSCs, which were blocked by Nlrp6 overexpression. ECRG4 knockdown reversed corticosterone-induced NSC mitochondrial function and cell proliferation disorders. Pioglitazone, a well-known clinical drug, up-regulated NLRP6 expression to inhibit ECRG4 expression in its protection against corticosterone-induced NSC mitochondrial dysfunction and proliferation restriction. In conclusion, this study demonstrates that NLRP6 is essential to maintain mitochondrial homeostasis and proliferation in NSCs, and identifies NLRP6 as a promising therapeutic target for hippocampal neurogenesis decline linked to depression.
