Individualized treatment of prostate cancer depends on an accurate stratification of patients who are sensitive to various treatments. Interleukin-23 (IL-23) was reported to play a significant role in prostate cancer. Here, we aimed to explore the clinical value of IL-23-secreting (IL-23+) cells in prostate cancer patients. We evaluated interleukin-23A (IL-23A) expression in The Cancer Genome Atlas database and retrospectively enrolled 179 treatment-naïve metastatic prostate cancer patients diagnosed in our institute between June 2012 and December 2014. IL-23⁺ cells were stained and evaluated via immunohistochemistry. Further, survival and multivariate Cox regression analyses were conducted to explore the prognostic value of IL-23⁺ cells. We found that IL-23A expression correlated with disease progression, while IL-23⁺ cells were clearly stained within prostate cancer tissue. Patients with higher Gleason scores and multiple metastatic lesions tended to have more IL-23⁺ cell infiltration. Further analyses showed that patients with higher levels of IL-23⁺ cells had significantly worse overall survival (hazard ratio [HR] = 2.996, 95% confidence interval [95% CI]: 1.812-4.955; P = 0.001) and a higher risk of developing castration resistance (HR = 2.725, 95% CI: 1.865-3.981; P = 0.001). Moreover, subgroup analyses showed that when patients progressed to a castration-resistant status, the prognostic value of IL-23⁺ cells was observed only in patients treated with abiraterone instead of docetaxel. Therefore, we showed that high IL-23⁺ cell infiltration is an independent prognosticator in patients with metastatic prostate cancer. IL-23⁺ cell infiltration may correlate with abiraterone effectiveness in castration-resistant prostate cancer patients.

OBJECTIVETo investigate the effect of Shenshao Decoction on the inflammatory status: in the aorta in a rat model of atherosclerosis.

METHODSForty Sprague-Dawley rats were randomly divided into: five groups, 8 rats in each group: control untreated group, atherosclerosis group, atherosclerosis with Shenshao Decoction (low dose) group, atherosclerosis with Shenshao Decoction (high dose) group, atherosclerosis with simvastatin group. To stimulate atherosclerosis, the rats were fed vitamin D3 and a high-cholesterol diet. Four weeks later, treatments were maintained for eight weeks. Morphology changes were investigated by hematoxylin and eosin staining. Serum levels of total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C) were obtained by enzymatic assays with use of an automated biochemical analyzer. The expression of malondialdehyde (MDA), glutathione peroxidase (GSH-PX) were detected by enzyme-enzymelinked immunosorbent assay. The expression levels of interleukin (IL)-1β, IL-17A, and IL-23 were detected by linked immunoblotting.

RESULTSShenshao Decoction treatment decreased TC, TG, LDL-C and MDA and increased: GSH-PX levels (P<0.01). Compared with the control group, IL-1β, IL-17A, and IL-23 were lower in the high and

CONCLUSIONShenshao Decoction: could attenuate the progression of aortal atherosclerotic plaques by inhibiting the inflammatory response in a rat atherosclerotic model.

In this study, we examined the therapeutic effects of an immune-stimulating peptide, WKYMVm, in ulcerative colitis. The administration of WKYMVm to dextran sodium sulfate (DSS)-treated mice reversed decreases in body weight, bleeding score and stool score in addition to reversing DSS-induced mucosa destruction and shortened colon. The WKYMVm-induced therapeutic effect against ulcerative colitis was strongly inhibited by a formyl peptide receptor (FPR) 2 antagonist, WRWWWW, indicating the crucial role of FPR2 in this effect. Mechanistically, WKYMVm effectively decreases intestinal permeability by stimulating colon epithelial cell proliferation. WKYMVm also strongly decreases interleukin-23 and transforming growth factor-beta production in the colon of DSS-treated mice. We suggest that the potent immune-modulating peptide WKYMVm and its receptor FPR2 may be useful in the development of efficient therapeutic agents against chronic intestinal inflammatory diseases.

OBJECTIVETo reveal the different molecular mechanisms between Chinese drugs for activating blood (CDAB) and Chinese drugs for nourishing qi and activating blood (CDNQAB) in the metastasis process of Lewis lung carcinoma, thus providing experimental reliance for Chinese drugs to reverse immune escape.

METHODSThe inhibition rate of lung metastasis was observed in each group. The dynamic percentage and ratio changes of Th17 and Treg cells in spleen CD4+ T lymphocytes were detected using flow cytometry. The dynamic levels of IL-17, IL-23, and gamma interferon (IFN-gamma) in the culture supernatant of CD4+ T lymphocytes were detected by ELISA. The dynamic mRNA expressions of Foxp3 and RORgammat in CD4+ T lymphocytes were detected by RT-PCR.

RESULTSCDNQAB (sapanwood +astragalus) showed better lung metastasis inhibiting rate than CDAB (sapanwood alone) (P<0.05), similar to the effects of cyclophosphamide (P>0.05). Except the CDNQAB group, spleen Th17 and Treg cells showed a rising tendency in mice of each tumor-bearing group. The effectors of Th17 and Treg cells (IL-17, IL-23, and IFN-gamma) and key transcription molecules of Th17 and Treg cells (RORgammat and Foxp3) showed dynamic changes corresponding to Th17 and Treg cells.

CONCLUSIONSThe immune inflammatory reactions of CDNQAB (sapanwood +astragalus) were superior to those of CDAB (sapanwood alone) and of cyclophosphamide during the process of inhibiting tumor immunotolerance and of the formation of tumor. All drugs showed certain inhibition on the mechanisms for neoplasm metastasis. But CD-NQAB was superior to CDAB and chemotherapeutics.

Inflammation is a part of the complex biological responses of a tissue to injury that protect the organ by removing injurious stimuli and initiating the healing process, and is considered as a mechanism of innate immunity. To identify biologically active compounds against pathogenic inflammatory and immune responses, we fractionated water, aqueous methanol and n-hexane layers from nine kinds of leguminosae and examined anti-inflammatory activity of the fractions in human keratinocytes and mouse skin. Among the fractions, rf3 and rf4, isolated from the aqueous methanol layer of Astragalus sinicus L., exhibited the strongest reactive oxygen species (ROS)-scavenging and anti-inflammatory activities as measured by inhibition of the intracellular ROS production, nuclear factor-kappaB (NF-kappaB), janus kinase (JAK)/signal transducer and activator of transcription (STAT), and phosphatidylinositol 3-kinase/Akt signaling in cytokine-stimulated human keratinocytes, as well as by effects on T-cell differentiation in mouse CD4+ T cells. In addition, topical application of rf3 and rf4 suppressed the progression of psoriasis-like dermatitis and expression of pro-inflammatory mediators in interleukin (IL)-23-injected mouse ears. Our results suggest that Astragalus sinicus L. may ameliorate chronic inflammatory skin diseases due to its antioxidant and anti-inflammatory activities via regulation of the intracellular ROS production, NF-kappaB, JAK/STAT and PI3/Akt signaling cascades as well as immune responses, and these results are the first report that Astragalus sinicus L. exhibits pharmacological activity.
