1Sodium oligomannate therapeutically remodels gut microbiota and suppresses gut bacterial amino acids-shaped neuroinflammation to inhibit Alzheimer's disease progression显示文摘Recently,increasing evidence has suggested the association between gut dysbiosis and Alzheimer's disease(AD)progression,yet the role of gut microbiota in AD pathogenesis remains obscure.Herein,we provide a potential mechanistic link between gut microbiota dysbiosis and neuroinflammation in AD progression.Using AD mouse models,we discovered that,during AD progression,the alteration of gut microbiota composition leads to the peripheral accumulation of phenylalanine and isoleucine,which stimulates the differentiation and proliferation of pro-inflammatory T helper 1(Thl)cells.The brain-infiltrated peripheral Th1 immune cells are associated with the Ml microglia aaivation,contributing to AD-associated neuroinflammation.Importantly,the elevation of phenylalanine and isoleucine concentrations and the increase of Th1 cell frequency in the blood were also observed in two small independent cohorts of patients with mild cognitive impairment(MCI)due to AD.Furthermore,GV-971,a sodium oligomannate that has demonstrated solid and consistent cognition improvement in a phase 3 clinical trial in China,suppresses gut dysbiosis and the associated phenylalanine/isoleucine accumulation,harnesses neuroinflammation and reverses the cognition impairment.Together,our findings highlight the role of gut dysbiosis-promoted neuroinflammation in AD progression and suggest a novel strategy for AD therapy by remodelling the gut microbiota.Xinyi Wang Guangqiang Sun Teng Feng Jing Zhang Xun Huang Tao Wang Zuoquan Xie Xingkun Chu Jun Yang Huan Wang Shuaishuai Chang Yanxue Gong Lingfei Ruan Guanqun Zhang Siyuan Yan Wen Lian Chen Du Dabing Yang Qingli Zhang Feifei Lin Jia Liu Haiyan Zhang Changrong Ge Shifu Xiao Jian Ding Meiyu Geng 2019Cell Research2019,29,10:192

3Regulation of glucose and lipid metabolism in health and disease显示文摘Glucose and fatty acids are the major sources of energy for human body. Cholesterol, the most abundant sterol in mammals, is a key component of cell membranes although it does not generate ATP. The metabolisms of glucose, fatty acids and cholesterol are often intertwined and regulated. For example, glucose can be converted to fatty acids and cholesterol through de novo lipid biosynthesis pathways. Excessive lipids are secreted in lipoproteins or stored in lipid droplets. The metabolites of glucose and lipids are dynamically transported intercellularly and intracellularly, and then converted to other molecules in specific compartments. The disorders of glucose and lipid metabolism result in severe diseases including cardiovascular disease, diabetes and fatty liver. This review summarizes the major metabolic aspects of glucose and lipid, and their regulations in the context of physiology and diseases.Ligong Chen Xiao-Wei Chen Xun Huang Bao-Liang Song Yan Wang Yiguo Wang 2019Science China(Life Sciences)2019,62,11:40

5Human umbilical cord mesenchymal stem cells promote peripheral nerve repair via paracrine mechanisms显示文摘Human umbilical cord-derived mesenchymal stem cells(h UCMSCs) represent a promising young-state stem cell source for cell-based therapy. h UCMSC transplantation into the transected sciatic nerve promotes axonal regeneration and functional recovery. To further clarify the paracrine effects of h UCMSCs on nerve regeneration, we performed human cytokine antibody array analysis, which revealed that h UCMSCs express 14 important neurotrophic factors. Enzyme-linked immunosorbent assay and immunohistochemistry showed that brain-derived neurotrophic factor, glial-derived neurotrophic factor, hepatocyte growth factor, neurotrophin-3, basic fibroblast growth factor, type I collagen, fibronectin and laminin were highly expressed. Treatment with h UCMSC-conditioned medium enhanced Schwann cell viability and proliferation, increased nerve growth factor and brain-derived neurotrophic factor expression in Schwann cells, and enhanced neurite growth from dorsal root ganglion explants. These findings suggest that paracrine action may be a key mechanism underlying the effects of h UCMSCs in peripheral nerve repair.Zhi-yuan Guo Xun Sun Xiao-long Xu Qing Zhao Jiang Peng Yu Wang 2015Neural Regeneration Research2015,10,4:26

7Atomically dispersed Au_1 catalyst towards efficient electrochemical synthesis of ammonia显示文摘Tremendous efforts have been devoted to explore energy-efficient strategies of ammonia synthesis to replace Haber–Bosch process which accounts for 1.4% of the annual energy consumption. In this study,atomically dispersed Au_1 catalyst is synthesized and applied in electrochemical synthesis of ammonia under ambient conditions. A high NH_4^+ Faradaic efficiency of 11.1% achieved by our Au_1 catalyst surpasses most of reported catalysts under comparable conditions. Benefiting from efficient atom utilization, an NH_4^+ yield rate of 1,305 lg h^(-1) mg_(Au)^(-1) has been reached, which is roughly 22.5 times as high as that by supported Au nanoparticles. We also demonstrate that by employing our Au_1 catalyst, NH4+can be electrochemically produced directly from N_2 and H_2 with an energy utilization rate of 4.02 mmol kJ^(-1). Our study provides a possibility of replacing the Haber–Bosch process with environmentally benign and energy-efficient electrochemical strategies.Xiaoqian Wang Wenyu Wang Man Qiao Geng Wu Wenxing Chen Tongwei Yuan Qian Xu Min Chen Yan Zhang Xin Wang Jing Wang Jingjie Ge Xun Hong Yafei Li Yuen Wu Yadong Li 2018Science Bulletin2018,63,19:22

Methods The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census(2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. Results The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. Conclusion The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups.YU Dong Mei ZHAO Li Yun YANG Zhen Yu CHANG Su Ying YU Wen Tao FANG Hong Yun WANG Xun YU Dan GUO Qi Ya XU Xiao Li FANG Yue Hui ZHAO Wen Hua YANG Xiao Guang DING Gang Qiang LIANG Xiao Feng 2016Biomedical and Environmental Sciences2016,29,3:18
12Identification of rice cultivars with low brown rice mixed cadmium and lead contents and their interactions with the micronutrients iron,zinc,nickel and manganese显示文摘Paddy fields in mining areas are usually co-contaminated by a cocktail of mixed toxic heavy metals(e.g.,Cd and Pb in Pb/Zn mines).However,previous studies on rice cultivars screened for effective metal exclusion have mostly focused on individual metals,and have been conducted under pot-trial or hydroponic solution conditions.This study identified rice cultivars with both low Cd and Pb accumulation under Cd-and Pb-contaminated field conditions,and the interactions of the toxic elements Cd and Pb with the micronutrient elements Fe,Zn,Mn and Ni were also studied.Among 32 rice cultivars tested,there were significant differences in Cd(0.06-0.59 mg/kg) and Pb(0.25-3.15 mg/kg) levels in their brown rice,and similar results were also found for the micronutrient elements.Significant decreases in concentrations of Fe and Mn were detected with increasing Cd concentrations and a significant elevation in Fe,Mn and Ni with increasing Pb concentrations.A similar result was also shown by Cd and Ni.Three cultivars were identified with a combination of low brown rice Cd and Pb,high micronutrient and grain yield(Wufengyou 2168,Tianyou 196 and Guinongzhan).Present results suggest that it is possible to breed rice cultivars with low mixed toxic element(Cd,Pb) and high micronutrient contents along with high grain yields,thus ensuring food safety and quality.Bing Li Xun Wang Xiaoli Qi Lu Huang Zhihong Ye 2012Journal of Environmental Sciences2012,24,10:18

14Intercropping with Solanum nigrum and Solanum photeinocarpum from Two Ecoclimatic Regions Promotes Growth and Reduces Cadmium Uptake of Eggplant Seedlings显示文摘Soil contamination by heavy metals is a serious environmental problem worldwide, and reduction of heavy metal accumulation in vegetables grown on contaminated land is a matter of urgency. A pot experiment was conducted to study the effects of intercropping with the Cd hyperaccumulators Solanum nigrum and Solanum photeinocarpum from two ecoclimatic regions, Ya'an and Chengdu,Sichuan Province, China, on the growth and cadmium(Cd) uptake of eggplant(Solanum melongena L.). The biomass, photosynthetic pigment contents, and activities of antioxidant enzymes of eggplant were enhanced by intercropping. The biomass of eggplant was the highest after intercropping with S. photeinocarpum from Ya'an, but did not differ significantly from that after intercropping with S. nigrum from Chengdu. The shoot Cd content of eggplant was significantly reduced by intercropping with the hyperaccumulators,which ranked as follows: S. nigrum from Chengdu > S. nigrum from Ya'an > S. photeinocarpum from Chengdu > S. photeinocarpum from Ya'an, with the decreases being 19.60%, 14.36%, 9.66%, and 6.42%, respectively, as compared with the control. The lowest shoot Cd content and translocation factor of eggplant were attained after intercropping with S. nigrum from Chengdu. Therefore, it was feasible to intercrop eggplant with S. nigrum and S. photeinocarpum on Cd-contaminated soil.TANG Yi HE Juan YU Xuena XIE Yongdong LIN Lijin SUN Guochao LI Huanxiu LIAO Mingan LIANG Dong XIA Hui WANG Xun ZHANG Jing LIU Zejing TU Lihua LIU Li 2017Pedosphere2017,27,3:17
15Downstaging and resection of hepatocellular carcinoma in patients with extrahepatic metastases after stereotactic therapy显示文摘Background:A combination of tyrosine kinase inhibitors(TKIs)and anti-PD-1 antibodies with local regional therapy has elicited yield substantial clinical benefits in patients who have hepatocellular carcinoma(HCC)with extrahepatic metastases.Using this treatment strategy to convert HCC patients with extrahepatic metastases from unresectable to resectable has not yet been reported.Methods:Consecutive hepatocellular carcinoma patients with extrahepatic metastases who received first-line therapy with a combination of TKIs and anti-PD-1 antibodies and at least one local regional therapy were analysed.Results:Nine patients with localized disease who received first-line systemic therapy were enrolled.At baseline,all of them had oligometastatic disease,namely,Barcelona Clinic Liver Cancer stage C(or Chinese Liver Cancer stage IIIB).The most common treatment administered was lenvatinib plus anti-PD-1 antibody and transarterial chemoembolization,and the median time span from systemic therapy to surgery was 3.2(IQR,2.8-6.2)months.Three patients achieved a pathological complete response.Six patients underwent laparoscopic surgery,and the other 3 patients underwent open surgery.After a median follow-up of 10.2(IQR,8.6-20.0)months,7 patients survived without disease recurrence,and 2 experienced tumour recurrence.All patients had any-grade AEs,and 55.6%of the patients experienced grade 3 AEs.Fatigue was the most common AE,followed by elevated aminotransferase levels and hypertension.Conclusions:Stereotactic therapy is a feasible conversion therapy for HCC patients with extrahepatic metastases to become resectable.This is the first study to analyse therapeutic outcomes of patients receiving these therapies for HCC with extrahepatic metastases.Xiaobo Yang Haifeng Xu Bangyou Zuo Xu Yang Jin Bian Junyu Long Dongxu Wang Junwei Zhang Cong Ning Yanyu Wang Ziyu Xun Yunchao Wang Xin Lu Yilei Mao Xinting Sang Haitao Zhao 2021Hepatobiliary Surgery and Nutrition2021,10,4:17
