Colorectal inflammatory cancer transformation poses a major risk to patients with colitis. Patients with chronic intestinal inflammation have an approximately 2-3 folds increased risk of developing colorectal cancer (CRC). Unfortunately, there is currently no effective intervention available. Huangqin decoction (HQD), a well-known traditional Chinese medicine (TCM) formula, is frequently clinically prescribed for treating patients with colitis, and its active ingredients have effective antitumour efficacy. Nonetheless, the mechanism of HQD-mediated prevention of colorectal inflammatory cancer transformation remains unclear. A strategy integrating metagenomic, lipidomic, and messenger RNA (mRNA) sequencing analysis was used to investigate the regulatory effects of HQD on the gut microbiome, metabolism and potential mechanisms involved in colorectal inflammatory cancer transformation. Our study revealed that HQD suppressed colorectal inflammatory cancer transformation, which was associated with enhanced intestinal barrier function, decreased the inflammatory response, and regulation of the gut microbiome. Notably, cohousing experiments revealed that the transfer of the gut microbiome from HQD-treated mice largely inhibited the pathological transformation of colitis. Moreover, gut microbiome transfer from HQD-treated mice primarily resulted in the altered regulation of fatty acid metabolism, especially the remodeling of arachidonic acid metabolism, which was associated with the amelioration of pathological transformation. Arachidonic acid metabolism and the key metabolic enzyme arachidonic acid 12-lipoxygenase (ALOX12) were affected by HQD treatment, and no obvious protective effect of HQD was observed in Alox 12 ^-/- mice, which revealed that ALOX12 was a critical mediator of HQD protection against colorectal inflammatory cancer transformation. In summary, multiple omics analyses were applied to produce valuable data and theoretical support for the application of HQD as a promising intervention for the transformation of inflammatory CRC.

Objective:To analyze the expression levels and clinical significance of interferon (IFN)-α/β in the renal cortex and serum of children with lupus nephritis (LN).Methods:A total of 32 children with LN diagnosed in the pediatric nephrology department of the Second Xiangya Hospital of Central South University from December 2017 to September 2020 were selected as the study subjects (LN group). The normal kidney control group consisted of 3 normal kidney transplant volunteers who underwent biopsy of kidney tissue (normal kidney control group), while 14 healthy children who underwent physical examination were collected as the normal control group. According to the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), LN patients were divided into mild activity group ( n=8), moderate activity group ( n=9), and severe activity group ( n=15). According to the International Society of Nephrology/Society of Nephrology (ISN/RPS) 2003 LN classification criteria, pathological classification was performed (3 cases in the mild pathological damage group, 8 cases in the moderate pathological damage group, and 11 cases in the severe pathological damage group); Immunohistochemistry was used to detect the expression and distribution of IFN-α/β in glomeruli and renal interstitium; Enzyme linked immunosorbent assay (ELISA) was used to detect the concentration of IFN-α/β in serum samples and analyze its correlation with the pathological classification and disease activity of LN patients. Results:The serum and renal cortex IFN-α/β levels in the LN group were higher than those in the normal control group and normal kidney control group, respectively (all P<0.05). The average level of serum IFN-α/β in the heavy activity group was higher than that in the light and moderate activity groups (all P<0.05). The serum and renal cortex IFN-α/β levels in the severe pathological damage group were significantly higher than those in the mild and moderate pathological damage groups (all P<0.05). Conclusions:IFN-α/β in the renal cortex is closely related to renal injury in LN; Serum IFN-α/β can assist in evaluating the disease activity level of LN to a certain extent.

Objective:To study the inhibitory effect of endothelial progenitor cells (EPCs) on aortic injury in mice with systemic lupus erythematosus (SLE) arteriosclerosis.Methods:APOE -/- mice were injected with norphytane and high fat diet to establish lupus vascular injury model. Then the mice were divided into normal control group (ND group), high fat diet group (HFD group), high fat diet+ SLE vascular injury group (HFD+ SLE group), high fat diet+ SLE vascular injury+ hydroxychloroquine treatment group (HFD+ SLE+ Hydro group), high fat diet+ SLE vascular injury+ EPCs treatment group (HFD+ SLE+ EPCs group). At the end of the experiment, urine, blood and aortic tissues of mice in each group were collected, and the content of urinary protein and the depth of serum type I interferon (IFN-Ⅰ) were detected by enzyme linked immunosorbent assay (ELISA). The activation of cyclic guanosine monophosphate synthase/interferon gene stimulating factor/type I interferon (cGAS/STING/IFN-Ⅰ) pathway, the levels of inflammatory factors, adhesion fractions and chemokines in the aorta of mice in each group were detected by immunohistochemistry and Western blotting (WB). The lipid deposition in the aorta was detected by oil red staining. Results:The results of ELISA showed that the levels of urinary protein and serum IFN-Ⅰ in HFD+ SLE group were higher than those in normal control group. EPCs treatment could reduce the levels of urinary protein and serum IFN-Ⅰ in SLE atherosclerotic mice. WB results showed that the expression of CD19, CD68, CD34, chemokine, cGAS, p-STING, phosphorylated TANK binding kinase 1 (p-TBK1), phosphorylated interferon regulatory factor 3 (p-IRF3) and IFN-Ⅰ increased in HFD+ SLE group, and hydroxychloroquine and EPCs decreased the levels of these factors. CGAS/STING/IFN-Ⅰ signal pathway is involved in the occurrence and development of atherosclerosis in SLE patients; both EPCs and hydroxychloroquine can inhibit the activation of cGAS/STING/IFN-Ⅰ signal, thus reducing atherosclerosis in SLE mice.Conclusions:cGAS/STING/IFN-Ⅰ pathway is involved in the development of SLE atherosclerosis. EPCs can inhibit the activation of cGAS/STING signal, reduce the expression and secretion of IFN-Ⅰ, and then reduce vascular inflammation and inhibit the development of SLE-related atherosclerosis.
