Objective:To evaluate the quantity and function changes of dendritic cells ( DC) in peripheral blood of patients with repeated implantation failure ( RIF).Methods:30 patients with RIF and 15 normal controls were enrolled in this study,and the peripheral blood was collected during the mid-luteal phase.The percentage of DC subsets and the expression levels of functional molecules were assessed by flow cytometric analysis.Results:Compared with normal controls,the percentage of lin-HLA-DR+DC cells accounting for leukocytes in patients with RIF was not significantly different ( P>0.05).There were also no significant differences in the expression levels of co-stimulatory molecules ( CD80 and CD86) and immune tolerant molecules CD200 on DC cells surfaces between patients with RIF and normal controls ( all P>0.05).In addition,the percentage of CD11c+CD123-mDC accounting for DC cells was significantly increased in patients with RIF (P<0.05),however,the percentage of CD11c-CD123+pDC was similar (P>0.05). Conclusion:The percentage of mDC accounting for DC cells was significantly increased in patients with RIF, which may be one of factors affecting pregnancy outcomes.

Objective To assess the in vitro effect of high intensity narrow-band blue light on bacteria isolated from patients with acne vulgaris (AV). Methods Bacteria were isolated by culture from the acne lesions of 67 patients with mild to moderate AV. Selected bacterial strains were chosen for irradiation with the blue light. The morphology and number of colony formation units (CFUs) as well as the ultrastructure of the bacteria were observed before and after the irradiation. Results Propionibacterium acnes (P. acnes) (32.4%), P. granulosum (6.9%), Staphylococcus epidermidis (S. epidermidis) (35.3%), S. aureus (4.9%), S. heamolyticus (7.8%), S.cohnii (1.0%), Corynebacterium spp. (9.8%), Klebsiella pneumoniae (1.0%) and B group Streptococci (1.0%) were isolated from the lesions. In vitro investigation revealed that the irradiation significantly reduced the number of CFUs of P. acne and S. epidermidis. Conclusion High intensity narrow-band blue light is effective against bacteria isolated from AV lesions.

The purpose of the study was to observe the effect of rapamycin (RAPA) on the differentiation and maturation of rat bone marrow-derived dendritic cells (BMDCs) in vitro. BMDCs from Wistar rats were cultured with granulocyte-macrophage colony-stimulating factor plus interleukin-4 in the presence or absence of RAPA (20 ng/mL), and stimulated with lipopolysaccharide (LPS) for 24 h before cells and supernatants were collected. Surface phenotype of BMDCs was flow-cytometrically detected to determine the expression of maturation markers, MHC class II and CD86. Supernatants were analyzed for the production of IL-12 and IFN-gamma cytokines by using ELISA. BMDCs were co-cultured with T cells from Lewis rats and mixed lymphocyte reaction was assessed by MTT method. The morphology of BMDCs stimulated with LPS remained immature after RAPA pretreatment. RAPA significantly decreased the CD86 expression, impaired the IL-12 and IFN-gamma production of BMDCs stimulated with LPS, and inhibited the proliferation of allogeneic T cells. In conclusion, RAPA can inhibit the maturation of BMDCs stimulated with LPS in terms of the morphology, surface phenotype, cytokine production, and ability of BMDCs to stimulate the proliferation of allogeneic T cells in vitro.

Background Interleukin-17 (IL-17)is a potent pro-inflammatory cytokine and plays a pathogenic role in autoimmune disease.It was confirmed that IL-17 is implicated in allograft rejection of many transplanted organs.Recent studies have foensed on the effect of IL-17 antagonists on allograft rejection.Objective This study aimed to investigate the inhibitory effect of anti-mouse IL-17 monoclonal antibody (mAb) on corneal allograft rejection.Methods Twenty-five 8 to 10-week-old C57BL/6 mice and 50 BALB/c mice were collected.Donor cornea grafts with 2 mm diameter from 25 C57BL/6 mice was transplanted to 50 eye of BALB/c mice to establish a model of corneal transplantation.The recipients were randomized into 2 groups,and neutralizing mouse IL-17antibody or isotype control antibody was intraperitoneally injected immediately after transplantation for experimental treatment,respectively.Allografts were scored clinically at appropriate time points after treatment based on Plskova criteria,and ≥5 was confirmed as rejection.Infiltrating cells in corneal graft were detected qualitatively and quantitatively by immunohistochemistry and reverse transcription-PCR separately.The cytokine levels of T helper type 1 (Th1),Th2,and Th17 in recipients' spleen wer(c) analyzcd by ELISA.The use of the animals followed the Statement of ARVO.Results Compared with the isotype control antibody group,the survival of grafts was improved in the IL-17mAb group(P＜0.05).The levels of neutrophile granulocyte mRNA,CD4+ and CD8+ T lymphotes mRNA were 2.22±0.10,1.64±0.04 and 1.32±0.10 in the IL-17 mAb group,showing a significant decline in comparison with those of the isotype control antibody group(3.61 ±0.08,2.69±0.06 and 2.17±0.04) (P=0.000,0.000,0.000).Interferon-γ(IFN-γ),IL-12 p40 and IL-17 concentrations in recipients ' splenocytes were (529.80 ± 13.83) ng/L,(539.58 ±10.74) ng/L and(173.70±8.11)ng/L in the IL-17 mAb group,and thosc in the isotype control antibody group were (741.48± 10.51) ng/L,(1156.90 ± 69.93) ng/L and (366.13± 7.93) ng/L,with significant differences between them (P=0.000,0.001,0.000).Conclusions Neutralization IL-17 bioactivity inhibits mouse corneal allograft rejection to a certain extent.

This paper aims to investigate the regulatory mechanism of blood-activating and stasis-dissipating drugs on fecal metabolic characteristics of rhubarb-peach kernel in mice with adenomyosis (AM) using fecal metabolome method. Adenomyosis was modeled by pituitary transplantation, and after the end of modeling administration, fecal samples were collected from mice. Non-targeted metabolomics studies were performed using liquid chromatography-mass spectrometry (LC-MS) to compare the metabolic characteristics of the feces of mice in each group and to find intestinal differential metabolites and potential differential metabolic pathways. The results showed that compared with the normal group, 5-hydroxy-L-tryptophan, histidine, L-acetylcarnitine, 16-hydroxy hexadecanoic acid, thromboxane B₂, etc. were significantly up-regulated, L-urobilin and prostaglandin D₃ were down-regulated in the feces of the model group, and were reversed after treatment with the rhubarb-peach kernel. The results of metabolic pathway enrichment analysis showed that tryptophan metabolism and histidine metabolism were the main intervention pathways of the rhubarb-peach kernel on AM intestinal metabolism. This study found that the underlying mechanism of the rhubarb-peach kernel in the treatment of AM is related to the intervention of intestinal metabolism of tryptophan, histidine, bile acid, choline and arachidonic acid, and the regulation of pro-inflammatory microenvironment and fatty acid metabolic homeostasis. This study has been approved by the Experimental Animal Ethics Committee of China Three Gorges University (No. 20190801).
