1Sini powder ameliorates the inflammatory response in rats with stress-induced non-alcoholic fatty liver disease by inhibiting the nuclear factor kappa-B/pyrin domain-containing protein 3 pathway显示文摘OBJECTIVE: To evaluate the effectiveness of Sini powder for the treatment of non-alcoholic fatty liver disease(NAFLD) in rats and the molecular mechanisms involved.METHODS: A rat model of stress-induced NAFLD was established by a combination of long-term tethering and feeding of a high-fat, high-calorie diet. These rats were then intragastrically administered with either simvastatin, Sini powder, or vehicle for 1 week. The body mass and field test scores for each group were recorded weekly. Serum aspartate aminotransferase and alanine aminotransferase activities, and triglyceride, total cholesterol,and free fatty acid concentrations were measured.Liver tissue histopathology was examined on hematoxylin and eosin-stained paraffin sections and oil red O-stained frozen sections. The hepatic m RNA expression of nuclear factor kappa-B(NF-κB),NOD-, LRR-, and pyrin domain-containing protein 3(NLRP3), apoptosis-associated speck-like protein containing CARD(ASC), and caspase-1 were measured by reverse transcription-polymerase chain reaction(RT-PCR). The hepatic protein concentrations of NF-κB and NLRP3, ASC, caspase-1, interleukin-1β(IL-1β), interleukin-6(IL-6), and the serum concentrations of IL-1β and IL-6 were measured by enzyme-linked immunosorbent assay.RESULTS: Compared with the Blank group, rats in the Compound model group showed significant pathologic manifestations of NAFLD, and the expression of NF-κB, NLRP3, ASC, caspase-1, IL-1βand IL-6 were significantly higher(all P < 0.01). Both simvastatin and Sini powder significantly ameliorated the NAFLD pathology and the abnormal expression of NF-κB, NLRP3, ASC, caspase-1, IL-1β, and IL-6(all P < 0.01).CONCLUSION: Sini powder inhibits the inflamma-tory response in rats with NAFLD, which is mediated by NF-κB/NLRP3, IL-1β, and IL-6, reduces the effects of psychological stress, and improves lipid metabolism. Therefore, Sini powder may be effective for the treatment of stress-related NAFLD through multiple mechanisms.Mu Jie Cheng Fafeng Wang Qingguo Wang Xueqian Zhu Wenxiang Ma Chongyang Yin Xiangjun Ren Beida Lian Yajun Du Xin Zhang Haixia Liu Shuling Zhang Shuang 2020Journal of Traditional Chinese Medicine2020,40,2:9
2Resonant transparency of a planar anapole metamaterial at terahertz frequencies显示文摘Anapole metamaterials have attracted growing attention in recent years due to their unique nonradiating and nontrivial properties. Although anapole modes have been demonstrated in metamaterials with threedimensional structures, the design and realization of planar anapole metamaterials in a wide frequency range is still a big challenge. Here we propose and experimentally demonstrate a planar anapole metamaterial consisting of dumbbell-shaped apertures on a stainless-steel sheet at terahertz frequencies. The planar metamaterial can generate a resonant transparency in the terahertz spectrum due to the excitation of the anapole mode.Particularly, the frequency of anapole-induced resonant transparency can be tuned easily in the range of 0.15–0.93 THz by simply varying one geometric parameter of the dumbbell apertures. We anticipate that the resonant transparency in planar anapole metamaterials can be potentially used in filters, sensors, or other photonic devices.XIANGJUN LI JIE YIN JIANJUN LIU FANGZHOU SHU TINGTING LANG XUFENG JING ZHI HONG 2021Photonics Research2021,9,2:2
3Consistent response of nematode communities to management of coniferous plantations显示文摘Background:Crop-tree thinning (CTT) is a forest management practice aiming at enhancing the growth of target trees in plantations by harvesting neighboring trees. Along with the positive effect on tree growth, thinning represents a disturbance, which likely affects belowground organisms and may feed back to stand productivity.However, the impact of CTT on the belowground food web is poorly understood. Since nematodes are species-rich and abundant belowground organisms, occupying a variety of trophic positions in soil food webs and being sensitive to disturbances, they serve as ecological indicators of ecosystem disturbance.Results:We studied the effect of CTT on the soil nematode community structure in pine (Pinus massoniana Lamb.),Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.) and cypress (Cupressus funebris Endl.) plantations in the Sichuan Basin three years after applying CTT. Crop-tree thinning significantly increased the abundance of soil nematodes in each of the plantations. Moreover, CTT significantly increased the relative abundance of herbivorous nematodes in each of the plantations. Furthermore, CTT increased the proportion of stress tolerators (c-p 1)and enrichment opportunists (c-p 2) and reduced the maturity, structure and enrichment indices of nematodes in Chinese fir and cypress plantations, while only subtle changes were observed in pine plantations. Interestingly,across plantations, the effects of CTT on soil nematode communities were mainly due to changes in microbial biomass nitrogen and understory vegetation diversity.Conclusions:Forest management practices resulting in more open canopies uniformly affect soil food webs by changing the quantity and quality of resources associated with increased understory cover and diversity as well as microbial food. These insights increase our understanding of the impacts of forest management on the structure and functioning of belowground communities, which may contribute to management and conservation policies for more sustainable forestry.Haifeng Yin Yu Su Size Liu Xiangjun Li Xianwei Li Chuan Fan Pingting Guan Zhijing Xie Simin Wang Stefan Scheu Valentyna Krashevska 2022Forest Ecosystems2022,9,4:1

6Presence of Rare Variants is Associated with Poorer Survival in Chinese Patients with Amyotrophic Lateral Sclerosis显示文摘Amyotrophic lateral sclerosis(ALS)is a fatal neurodegenerative disorder with phenotypic and genetic heterogeneity.Recent studies have suggested an oligogenic basis of ALS,in which the co-occurrence of two or more genetic variants has additive or synergistic deleterious effects.To assess the contribution of possible oligogenic inheritance,we profiled a panel of 43 relevant genes in 57 sporadic ALS(sALS)patients and eight familial ALS(fALS)patients from five pedigrees in east China.We filtered rare variants using the combination of the Exome Aggregation Consortium,the 1000 Genomes and the HuaBiao Project.We analyzed patients with multiple rare variants in 43 known ALS causative genes and the genotype–phenotype cor-relation.Overall,we detected 30 rare variants in 16 different genes and found that 16 of the sALS patients and all the fALS patients examined harbored at least one variant in the investigated genes,among which two sALS and four fALS patients harbored two or more variants.Of note,the sALS patients with one or more variants in ALS genes had worse survival than the patients with no variants.Typically,in one fALS pedigree with three variants,the family member with three variants(Superoxide dismutase 1(SOD1)p.V48A,Optineurin(OPTN)p.A433V and TANK binding kinase 1(TBK1)p.R573H)exhibited much more severe disease phenotype than the member carrying one variant(TBK1 p.R573H).Our findings suggest that rare variants could exert a negative prognostic effect,thereby supporting the oligogenic inheritance of ALS.Siqi Dong Xianhong Yin Kun Wang Wenbo Yang Jiatong Li Yi Wang Yanni Zhou Xiaoni Liu Jiucun Wang Xiangjun Chen 2023Phenomics2023,3,2:0
