Food Science and Human Wellness 2024年

作者： Jiang Man Xiuyan Sun Xiaobo zhang Ning yu Dajun Xu Ying Chen Jijuan cao Key Laboratory of Biotechnology and Bioresources Utilization of Ministry of education， Dalian Minzu University Chinese Academy of Inspection and Quarantine China Association for Standardization

To solve the problem of the lack of reference material （RM） for determination of allergenic ingredients in food， a RM of cashew nut powder was developed in the study. Cashew nut powder was prepared from cashew nut kernel by selecting， cleaning， crushing， n-hexane degreasing and sieving treatment. The reliability and traceability of RM was verified using real-time quantitative polymerase chain reaction （qPCR） and phylogenetic tree analysis. The cashew nut powder RM showed good homogeneity， and good stability under long-term storage at 4℃ and short-term simulated transportation from -20℃ to 45℃. The RM was determined jointly by 8 collaborative laboratories， and the characteristic CTvalue was 24.732， and the extended uncertainty was 1.052 （k=2）. The RM was applied to verify the amplification efficiency （e）and the limit of detection （LOD） for qPCR assay， and showed good applicability. The RM could be used for method validation and quality control， for the determination of allergenic ingredients in food mixed with trace amounts of cashew nut.

Objective This study aimed to evaluate whether the onset of the plateau phase of slow hepatitis B surface antigen decline in patients with chronic hepatitis B treated with intermittent interferon therapy is related to the frequency of dendritic cell subsets and expression of the costimulatory molecules CD40,CD80,CD83,and *** This was a cross-sectional study in which patients were divided into a natural history group(namely NH group),a long-term oral nucleoside analogs treatment group(namely NA group),and a plateau-arriving group(namely P group).The percentage of plasmacytoid dendritic cell and myeloid dendritic cell subsets in peripheral blood lymphocytes and monocytes and the mean fluorescence intensity of their surface costimulatory molecules were detected using a flow *** In total,143 patients were enrolled(NH group,n=49;NA group,n=47;P group,n=47).The results demonstrated that CD141/CD1c double negative myeloid dendritic cell(DNmDC)/lymphocytes and monocytes(%)in P group(0.041[0.024,0.069])was significantly lower than that in NH group(0.270[0.135,0.407])and NA group(0.273[0.150,0.443]),and CD86 mean fluorescence intensity of DNmDCs in P group(1832.0[1484.0,2793.0])was significantly lower than that in NH group(4316.0[2958.0,5169.0])and NA group(3299.0[2534.0,4371.0]),Adjusted P alleduced DNmDCs and impaired maturation may be associated with the onset of the plateau phase during intermittent interferon therapy in patients with chronic hepatitis B.

Increase of PCSK9 expression in diabetes promotes VeGFR2ubiquitination to inhibit endothelial function and skin wound healing

Diabetic foot ulcers（DFUs） are a serious vascular disease. Currently, no effective methods are available for treating DFUs. Pro-protein convertase subtilisin/kexin type 9（PCSK9） regulates lipid levels to promote atherosclerosis. However, the role of PCSK9 in DFUs remains unclear. In this study, we found that the expression of PCSK9 in endothelial cells（eCs） increased significantly under high glucose（HG）stimulation and in diabetic plasma and vessels. Specifically, PCSK9 promotes the e3 ubiquitin-protein ligase NeDD4 binding to vascular endothelial growth factor receptor 2（VeGFR2）, which led to the ubiquitination of VeGFR2, resulting in its degradation and downregulation in eCs. Furthermore, PCSK9 suppresses the expression and activation of AKT, endothelial nitric oxide synthase（eNOS）, and eRK1/2, leading to decreased nitric oxide（NO） production and increased superoxide anion(O2·-) generation, which impairs vascular endothelial function and angiogenesis. Importantly, using evolocumab to limit the increase in PCSK9 expression blocked the HG-induced inhibition of NO production and the increase in O2·-production, as well as inhibited the phosphorylation and expression of AKT, eNOS, and eRK1/***, evolocumab improved vascular endothelial function and angiogenesis, and promoted wound healing in diabetes. Our findings suggest that targeting PCSK9 is a novel therapeutic approach for treating DFUs.
