We has studied the feasibility of preventing protein from denature during covalent immobilization by "conformation memory", which was achieved by freeze-drying under enzyme active conformation and cross-linked with carrier under micro-aqueous media (MAM). Horseradish peroxidase (HRP) and chitosan beads have been used as the model enzyme and carrier. The MAM consisted of 99% dioxane and 1% water. We compared the immobilized HRP under MAM with that under traditional aqueous solvent, found that the optimum temperature of both was raised to 60 degrees C, and the optimum pH was 6.5. However, the MAM-immobilized HRP had shown less activity loss during usage and six times higher activity than that immobilized under aqueous solvent. After 30 min incubation at 70 degrees C, the MAM-immobilized HRP remained 75.42% activity while the aqueous-media-immobilized enzyme only 15.4%. The MAM-immobilized HRP has shown a better operation stability with 77.69% residue activity after 5 times of repeat operation while the aqueous-media-immobilized enzyme only 16.67%. In addition, the MAM-immobilized HRP had also shown more advantages when used in phenol removal. We constructed enzyme electrodes (CS-HRP-SWCNTs/Au) to further display the different properties of the two immobilized HRP. MAM-immobilized HRP-electrode has shown two times stronger response signal to H2O2 than that immobilized under aqueous media, which indicated a better enzyme activity of MAM-immobilized HRP. Our research demonstrated that the conformation memory, to some extent, did contribute to preventing protein from denaturing when use HRP as a model, and it is feasible to immobilize enzyme by covalent cross-linking method under micro-aqueous media.

OBJECTIVEPsoriasis is an autoimmune-related chronic inflammatory skin disease strongly associated with the dysfunction of Th17 cells. Retinoic acid-related orphan nuclear receptor γt (RORγt) plays a critical role in the differentiation and maturation of Th17 cells and in cell-derived immunologic derangement. We conducted this study to investigate potential mechanism by which the derivative of digoxin selectively antagonizes RORγt transcriptional activity.
METHODUsing molecular docking in combination with molecular electrostatic potential (MEP), we detected the interaction between the derivative of digoxin (Dhd) and ROR transcription factor (RORα,RORβ and RORγt), and the results were further confirmed by bioluminescent assay.
RESULTMolecular docking demonstrated that Dhd could exclusively inhibit the conformation of RORγt; bioluminescent assay further indicated that RORγt was selectively antagonized by Dhd in a dose- and time-dependent manner.
CONCLUSIONDhd can selectively suppress RORγt transcriptional activity.

ObjectiveTo investigate the mechanism of Xumingtang in Gu Jin Lu Yan (《古今录验》) in regulating cell pyroptosis through the hypoxia-inducible factor-1α (HIF-1α)/NOD-like receptor pyrin domain-containing protein 3 (NLRP3) pathway in ischemic stroke (IS). MethodSD rats were randomly divided into a sham operation group, a model group, low- and high-dose Xumingtang groups, and a metformin group, with 20 rats in each group. Oral administration was performed for 3 days, and tissue samples were collected. Differential messenger RNA (mRNA) was screened using high-throughput sequencing, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed on key differentially expressed genes. The modified neurological severity score (mNSS) and 2,3,5-triphenyltetrazolium chloride (TTC) staining were used to evaluate the effect of brain infarction. Hematoxylin-eosin (HE) staining was used for pathological morphological observation of brain tissue. Enzyme-linked immunosorbent assay (ELISA) was used to compare the levels of interleukin-1β (IL-1β) and interleukin-18 (IL-18) in the ischemic cortical region. Double staining immunohistochemistry was used to detect the co-localization of HIF-1α and NLRP3. Real-time quantitative polymerase chain reaction (PCR) was performed to detect the mRNA expression of NLRP3, HIF-1α, Caspase-1 (CASP-1), and gasdermin D (GSDMD). Western blot was used to detect the protein expression of HIF-1α, NLRP3, CASP-1, and GSDMD. ResultA total of 5 705 differentially expressed genes (2 733 downregulated and 2 972 upregulated) were obtained by mRNA sequencing. After conversion to homologous genes and intersection with the pyroptosis gene set, 95 key differentially expressed pyroptosis genes were obtained. Compared with the sham operation group, the model group showed significantly increased mNSS scores, larger brain infarction areas (P<0.01), diverse neuronal morphology, disordered arrangement, widened cell gaps, significantly increased levels of IL-1β and IL-18 in the ischemic cortical region (P<0.01), enhanced co-localization fluorescence intensity, and significantly increased mRNA and protein expression levels of HIF-1α, NLRP3, CASP-1, and GSDMD (P<0.01). Compared with the model group, the high-dose Xumingtang group showed the most significant improvement in neurological function scores and brain infarction areas (P<0.01). The neuronal integrity and arrangement were more complete, and the cell gaps were narrower in all groups with drug treatment, with significantly reduced co-localization fluorescence intensity. Xumingtang could reduce the levels of IL-1β, IL-18, and the mRNA and protein expression of HIF-1α, NLRP3, CASP-1, and GSDMD (P<0.05, P<0.01), with the high-dose Xumingtang group showing the most significant effect (P<0.01). ConclusionXumingtang in Gu Jin Lu Yan can inhibit cell pyroptosis and promote neurological function recovery after IS, which may be related to the inhibition of the HIF-1α/NLRP3 pathway.
