Objective To test the level of follicular helper T cells (Tfh) and interleukin (IL)-21,CXCL13 in the peripheral blood of patients with ankylosing spondylitis (AS),and to analyze the relationship between Tfh and clinic features and explore the possible immunological pathogenesis of AS.Methods The Tfh cells were obtained from patients and normal controls and detected by flow cytometry.While the levels of IL-21,CXCL13 in patients and normal controls were measured by enzyme-linked immunosorbent assay (ELISA) tests.Data analysis were performed by Student's t-test,Rank-sum test,Spearman's correlation test.Results The expression of CD4+CXCR5 qCOS + cells (Tfh) (mean rank 33.71) and IL-21 [(299±27) ng/L],CXCL13 [(5.8±1.0) μg/L] in the peripheral blood of AS was significantly higher than normal controls [mean rank 23.54,(176±26) ng/L,(4.2±0.8) μg/L] (Z=-2.258,t=17.221,t=6.464,all P＜0.05).It was similar in AS with peripheral joint involvement compared with AS of non-peripheral joint involvement,and there was no difference between AS patients with positive HLA-B27 and those without HLA-B27.Mean -while,no correlation was found between the expression of Tfh,IL-21,CXCL13 and level of ESR,CRP,BASDAI.And there was no significant correlation between the expression of Tfh and IL-21,CXCL13 (P＞0.05).Conclusion The expression of Tfh and the levels of IL-21,CXCL13 are increased significantly,but are not closely relatedto disease activity.These results indicate that the abnormality of Tfh may play an important role in the pathogenesis of AS.

Objective To investigate the pathogenic significance of antigenic epitopes and their relevant antibodies in pemphigus vulgaris (PV) by neonatal mouse model. Methods The extracellular domain 1-2 (EC1-2) fusion protein was expressed and purified by glutathione affinity chromatography on the basis of construction of recombinant EC1-2 vector, and then the New Zealand white rabbits were immunized to obtain the specific antisera. The IgG fraction was transferred into the neonatal mice passively after it was purified from the antisera. After 15-18 hours of injection, the abdomen skin and the sera of the mice were examined by light microscopy, electron microscopy, direct immunofluorescence and indirect immunofluorescence. Results In the evaluation of the study group of mice, the intraepithelial vesicle formation was observed. Electron microscopy showed that intercellular spaces were widened, desmosome split and disappeared. In immunofluorescence, the fluorescence-labeled IgG deposied between the acantholytic cells. In the control group of mice there were no pathogenic changes observed, except very weak fluorescence between intercellular spaces. Conclusion The PV mouse model established shows that the EC1-2 epitope in PVA antigen and its relevant antibodies were pathogenic, and can be used as a tool in studying the pathogenesis of PV.

The study evaluates the lipolysis rate and extent of type Ⅲ lipid formulations using testosterone undecanoate as a model drug after digestion with in vitro lipolysis model, and studies the digestive regularity with optical microscope and electrical conductivity. The results showed that for testosterone undecanoate type Ⅲ lipid formulations with castor oil as oil phase and Transcutol HP as latent solvent, the lipolysis rate and extent were increased with the increase of oil phase proportion and were decreased with excessive proportion of surfactant, in which can see liquid crystal phase during lipolysis process. The lipolysis rate of type ⅢB lipid preparations with different surfactant were ordered as Labrasol > Tween 80 > Cremophor EL, but the rate of type ⅢA is different in quick digestion phase and slow digestion phase. The lipolysis extent of type Ⅲ lipid formulations with different surfactant were ordered as Cremophor EL > Tween 80 > Labrasol. These may be related to the digestive effect of pancreatic lipase on different surfactants. This study implied that the lipolysis rate and extent of type Ⅲ lipid formulations are greatly influenced by the proportion of oil phase and surfactant, and the surfactant structure. These factors will affect the in vivo digestion and should be taken into account when screening type Ⅲ lipid formulations.

The global incidence rate of nonalcoholic steatohepatitis (NASH) continues to rise. The pathogenesis of NASH is complex, and there is no effective clinical treatment. Previous study has shown that DEAD box protein 5 (DDX5) can significantly alleviate the NASH process in mice. This study screened the natural product library of the research group and found that the active compound hypercalin B (HB) in Hypericum beanii N. Robson, a traditional Chinese medicine, can upregulate the expression of DDX5 protein in a dose-dependent manner. In this study, an in vitro model of NASH stimulated by palmitic acid (PA) and an animal model of NASH induced by the methionine- and choline-deficient diet (MCD) were constructed. Different concentrations of HB were used to investigate the effect and mechanism of HB in alleviating NASH progression. All animal experiments in this paper were approved by the Ethics Committee of China Pharmaceutical University (NO: 2021-02-003). In vitro model results showed that HB significantly reduced the intracellular lipid deposition induced by free fatty acid (FFA). Animal experiments showed that HB improved liver injury by significantly reducing lipid accumulation in the liver of NASH mice, and reducing serum aspartate transaminase (AST) and alanine transaminase (ALT) levels. Moreover, HB could inhibit liver inflammation by reducing the mRNA levels of liver pro-inflammatory cytokines including interleukin 6 (IL-6), interleukin 1β (IL-1β), and tumor necrosis factor α (TNFα). Further research showed that HB could reduce the phosphorylation level of the mechanical target of rapamycin (mTOR) and reduce the expression of sterol regulatory element binding protein 1 (SREBP1) and fatty acid synthase (FASN), thereby improving lipid metabolism and alleviating NASH progression, and the effects of HB against NASH were dependent on DDX5. In conclusion, HB can improve lipid metabolism and inhibit inflammatory activation by suppressing mTORC1 pathway via upregulating DDX5 protein, and showed promising anti-NASH activity in vitro and in vivo.
