| 1 | Studies on Reducing Nitrogen Excretion: Ⅰ. Net Energy Requirement of Finishing Pigs Maximizing Performance and Carcass Quality Fed Low Crude Protein Diets Supplemented with Crystalline Amino Acids显示文摘Two experiments were conducted to investigate the effects of net energy (NE) level on the performance and carcass traits of finishing pigs fed low crude protein (CP) diets supplemented with crystalline amino acids (CAA). A total of 216 (Exp.1) and 360 (Exp.2) barrows (Yorkshire×Landrace×Duroc) were allotted to one of six treatments (n=6). The experimental diets were based on corn and soybean meal, and consisted of a highCP diet that contained approximately 16% CP and 2.50 Mcal/kg of NE as well as five lowCP diets in which the CP level of the diet was reduced by approximately four percentage units but was supplemented with crystalline lysine, methionine, threonine, and tryptophan. The low CP diets provided 2.64, 2.58, 2.50, 2.42, or 2.36 Mcal/kg in Exp.1 as well as 2.45, 2.40, 2.35, 2.30, or 2.25 Mcal/kg in Exp.2. In Exp.1, a linear (P=0.03) increase in weight gain was observed with decreasing NE level while the ratio of gain to feed was unaffected (P>0.05) by NE level. There was a linear increase (P=0.01) in the percentage of fatfree lean and a linear decrease (P=0.03) in the percentage of total fat with decreasing NE levels. In Exp.2, a significant quadratic (P=0.03) effect of NE level was observed for weight gain. The ratio of gain to feed demonstrated a significant (P<0.01) quadratic effect with pigs fed 2.35 and 2.40 Mcal/kg of NE. Pigs fed the diet containing 2.40 Mcal/kg of NE had the lowest percentage of total fat (36.95%) and the highest percentage of fatfree lean (49.36%). The overall results of these experiments indicate that feeding either a surplus or a deficiency of NE is detrimental to both pig performance and carcass composition when low CP diets supplemented with CAA are fed. Our results indicate that when the CP content of the diet is reduced by four percentage units and the diet is properly supplemented with CAA, maximum performance and carcass quality will be obtained if the diet provides approximately 2.42 Mcal/kg of NE. | Hongyu Chen Xuewu Yi Guijie Zhang Ning Lu Licui Chu P.

| 2 | O-glycosylation pattern of the SARS-CoV-2 spike protein reveals an “O-Follow-N” rule显示文摘Dear Editor,Severe acute respiratory syndrome coronavirus-2(SARS-CoV-2),the causative agent of coronavirus disease 2019(COVID-19),emerged in late 2019 and has since caused a pandemic.Although there have been extensive studies worldwide,our understanding of this newly emerged pathogen is far from sufficient.The pathogenesis of the SARS-CoV-2 infection is not fully understood,although a“two-stage”hypothesis was proposed in our previous study. | Wenmin Tian Delin Li Nan Zhang Guijie Bai Kai Yuan Haixia Xiao Feng Gao Yang Chen Catherine C.L.Wong George Fu Gao | 2021 | Cell Research2021，31，10： | 9 |
| 3 | Fermentation characteristics and probiotic activity of a purified fraction of polysaccharides from Fuzhuan brick tea显示文摘Polysaccharides from Fuzhuan brick tea(FBTPS),one of most important bioactive components in tea,showed various health-promoting functions.Our previous work demonstrated that the crude FBTPS(CFBTPS)could modulate the gut microbiota.However,which purified fraction in CFBTPS contributing to the modulation of gut microbiota remains unclear.Thus,the fermentation characteristics and probiotic activity of a purified fraction(FBTPS-2-1)of CFBTPS were evaluated in this work.The results showed that gut microbiota could utilize FBTPS-2-1 to produce short-chain fatty acids including acetic,propionic,n-butyric and n-valeric acids.FBTPS-2-1 could modulate the structure and metabolic pathways of gut microbiota.FBTPS-2-1 could increase the health-promoting gut microbiota such as Prevotellaceae and Bifidobacteriaceae,and decreased the harmful bacteria such as Enterobacteriaceae and Fusobacteriaceae.The results of metagenomics showed that Prevotella copri and Megamonas funiformis were the dominant bacteria after fermentation of FBTPS-2-1.Furthermore,FBTPS-2-1 could regulate the biosynthesis and metabolism pathways of gut microbiota.Thus,the enrichment of food with FBTPS-2-1 is expected as a potential strategy for promoting human health due to modulation of gut microbiota. | Guijie Chen Ziqi Zeng Minhao Xie Yujia Peng Wangting Zhou Weiqi Xu Yi Sun Xiaoxiong Zeng Zhonghua Liu | 2022 | Food Science and Human Wellness2022，11，3： | 4 |

| 7 | Effects of Strain Channel on Electron Irradiation Tolerance of InP-based HEMT Structures显示文摘The introduction of strain In_(x)Ga_(1-x)As channel with high In content increases the confinement of the two-dimensional electron gas(2DEG)and further improves the high-frequency performance of InGaAs/InAlAs/InP HEMTs.The effect of In_(x)Ga_(1-x)As channel with different In contents on electron irradiation tolerance of InP-based HEMT structures in terms of 2DEG mobility and density has been investigated.The experiment results show that,after the same high electron irradiation dose,the 2DEG mobility and density in InP-based HEMT structures with strain In_(x)Ga_(1-x)As(x>0.53)channel decrease more dramatically than that without strain In_(0.53)Ga_(0.47)As channel.Moreover,the degradation of 2DEG mobility and density becomes more severe as the increase of In content and strain in the In_(x)Ga_(1-x)As channel.The research results can provide some suggestions for the design of radiation-resistant InP-based HEMTs. | FANG Renfeng CAO Wenyu WEI Yanfeng WANG Yin CHEN Chuanliang YAN Jiasheng XING Yan LIANG Guijie ZHOU Shuxing | 2023 | 原子能科学技术2023，57，12： | 0 |

| 9 | Study on the interaction between β-carotene and gut microflora using an in vitro fermentation model显示文摘β-Carotene,a typical non-oxygenated carotenoid,is the most efficient source of retinol(VA).The low bio-availability ofβ-carotene lead to large accumulation in colon;however,the relationship betweenβ-carotene and gut microflora remains unclear.This study intends to explore the interaction betweenβ-carotene and gut microflora using an in vitro fermentation model.After 24 h fermentation,the degradation rate ofβ-carotene was(64.28±6.23)%,which was 1.46 times that of the group without gut microflora.Meanwhile,the production of VA was nearly 2 times that of the group without gut microflora,indicating that the gut microflora can metabolizeβ-carotene into VA.β-Carotene also influences the production of short-chain fatty acids(SCFAs),the production of total SCFAs in 0.5 mg/mLβ-carotene(BCM)group was(44.00±1.16)mmol/L,which was 2.26 times that of the blank control(BLK)group.Among them,the production of acetic acid in BCM group was(19.06±0.82)mmol/L,which was 2.64 time that of the BLK group.Furthermore,β-carotene significantly affected the structure and composition of gut microflora,increasing the abundance of Roseburia,Parasutterella and Lachnospiraceae,and decreasing the abundance of Dialister,Collinsella and Enterobacter(P<0.05).This study provides a new way to understand howβ-carotene works in human body with gut microflora. | Zhixian Li Zhuqing Dai Enjuan Shi Peng Wan Guijie Chen Zhongyuan Zhang Yayuan Xu Ruichang Gao Xiaoxiong Zeng Dajing Li | 2023 | Food Science and Human Wellness2023，12，4： | 0 |
| 10 | Double-ended passivator enables dark-current-suppressed colloidal quantum dot photodiodes for CMOS-integrated infrared imagers显示文摘Lead sulfide(PbS)colloidal quantum dot(CQD)photodiodes integrated with silicon-based readout integrated circuits(ROICs)offer a promising solution for the next-generation short-wave infrared(SWIR)imaging technology.Despite their potential,large-size CQD photodiodes pose a challenge due to high dark currents resulting from surface states on nonpassivated(100)facets and trap states generated by CQD fusion.In this work,we present a novel approach to address this issue by introducing double-ended ligands that supplementally passivate(100)facets of halidecapped large-size CQDs,leading to suppressed bandtail states and reduced defect concentration.Our results demonstrate that the dark current density is highly suppressed by about an order of magnitude to 9.6 nA cm^(2) at^(-1)0 mV,which is among the lowest reported for PbS CQD photodiodes.Furthermore,the performance of the photodiodes is exemplary,yielding an external quantum efficiency of 50.8%(which corresponds to a responsivity of 0.532 A W^(-1))and a specific detectivity of 2.5×10^(12) Jones at 1300 nm.By integrating CQD photodiodes with CMOS ROICs,the CQD imager provides high-resolution(640512)SWIR imaging for infrared penetration and material discrimination. | Peilin Liu Shuaicheng Lu Jing Liu Bing Xia Gaoyuan Yang Mo Ke Xuezhi Zhao Junrui Yang Yuxuan Liu Ciyu Ge Guijie Liang Wei Chen Xinzheng Lan Jianbing Zhang Liang Gao Jiang Tang | 2024 | InfoMat2024，6，1： | 0 |
| 11 | Associations Between Air Temperature and Daily Varicella Cases—Jinan City,Shandong Province,China,2019–2021显示文摘Summary What is already known about this topic?The impact of air temperature on varicella has been studied,but there is limited research exploring its effect on varicella by gender and age group.What is added by this report?We conducted a time series analysis to examine the differential effects of air temperature on varicella infection across different demographic groups.Our findings indicate that lower temperatures have a more pronounced influence on varicella incidence among males and children compared to females and adults.What are the implications for public health practice?These findings can assist in identifying populations that are vulnerable to temperature-related varicella and in guiding the implementation of effective measures for varicella control. | Guijie Luan Yuehua Hu Meng Chen Meiying You Chengdong Xu Dapeng Yin Jianjun Liu Hongyan Yao | 2024 | China CDC weekly2024，6，2： | 0 |
| 12 | G protein-coupled receptor 35 attenuates nonalcoholic steatohepatitis by reprogramming cholesterol homeostasis in hepatocytes显示文摘Nonalcoholic fatty liver disease(NAFLD)is the most common chronic liver disease worldwide.Fat accumulation“sensitizes”the liver to insult and leads to nonalcoholic steatohepatitis(NASH).G protein-coupled receptor 35(GPR35)is involved in metabolic stresses,but its role in NAFLD is unknown.We report that hepatocyte GPR35 mitigates NASH by regulating hepatic cholesterol homeostasis.Specifically,we found that GPR35 overexpression in hepatocytes protected against high-fat/cholesterol/fructose(HFCF)diet-induced steatohepatitis,whereas loss of GPR35 had the opposite effect.Administration of the GPR35 agonist kynurenic acid(Kyna)suppressed HFCF diet-induced steatohepatitis in mice.Kyna/GPR35 induced expression of StAR-related lipid transfer protein 4(STARD4)through the ERK1/2 signaling pathway,ultimately resulting in hepatic cholesterol esterification and bile acid synthesis(BAS).The overexpression of STARD4 increased the expression of the BAS rate-limiting enzymes cytochrome P450 family 7 subfamily A member 1(CYP7A1)and CYP8B1,promoting the conversion of cholesterol to bile acid.The protective effect induced by GPR35 overexpression in hepatocytes disappeared in hepatocyte STARD4-knockdown mice.STARD4 overexpression in hepatocytes reversed the aggravation of HFCF diet-induced steatohepatitis caused by the loss of GPR35 expression in hepatocytes in mice.Our findings indicate that the GPR35–STARD4 axis is a promising therapeutic target for NAFLD. | Xiaoli Wei Fan Yin Miaomiao Wu Qianqian Xie Xueqin Zhao Cheng Zhu Ruiqian Xie Chongqing Chen Menghua Liu Xueying Wang Ruixue Ren Guijie Kang Chenwen Zhu Jingjing Cong Hua Wang Xuefu Wang | 2023 | Acta Pharmaceutica Sinica B2023，13，3： | 0 |
| 13 | Theasinensin A attenuated diabetic development by restoring glucose homeostasis, improving hepatic steatosis and modulating gut microbiota in high-fat-diet/streptozotocin-induced diabetic mice显示文摘Theasinensin A(TSA),a dimer of epigallocatechin gallate,has been preliminarily demonstrated to have hypoglycemia and anti-inflammatory effects.However,little information is available on its potential mechanisms of anti-diabetes.Therefore,the present study aimed to investigate the influence of TSA on glucose and lipid metabolism and gut microbiota in high-fat-diet/streptozotocin-induced diabetic mice.As result,TSA improved polydipsia,polyphagia and impaired glucose tolerance of diabetic mice,declined the fasting blood glucose and hepatic triglyceride level,and enhanced the expression at mRNA level of insulin receptor substrate,phosphoinositide 3-kinase,protein kinase B and glucagon-like peptide 1 receptor(GLP-1R)in the diabetic liver.Moreover,TSA could restore the disorder of gut microbiota of diabetic mice.High-dose(100 mg/kg)TSA showed better benefi cial effects from the blood biochemical parameters,hepatic function and gut microbiota.In general,high-dose TSA significantly modulated gut microbiota by increasing the relative abundance of Akkermansia and decreasing the relative abundances of Acetatifactor,Anaerotruncus,Pseudofl avonifactor,Oscillibacter and Clostridium clusters.The results indicated that TSA could exert an anti-diabetes effect in diabetic mice through restoring glucose homeostasis,declining hepatic steatosis,activating insulin and GLP-1 signaling pathways,and ameliorating gut microbiota dysbiosis. | Weiqi Xu Yujie Huang Wangting Zhou Yujia Peng Xuhui Kan Wei Dong Guijie Chen Xiaoxiong Zeng Zhonghua Liu | 2023 | Food Science and Human Wellness2023，12，6： | 0 |
| 14 | 2-O-β-D-Glucopyranosyl-L-ascorbic acid,an ascorbic acid derivative isolated from the fruits of Lycium barbarum L.,ameliorates high fructose-induced neuroinflammation in mice:involvement of gut microbiota and leaky gut显示文摘Western diet(rich in highly refined sugar and fat)can induce a range of metabolic dysfunctions in animals and humans,including neuroinflammation and cognitive function decline.Neuroinflammation and cognitive impairment,two critical pathological characteristics of Alzheimer’s disease,have been closely associated with microbial alteration via the gut-brain axis.Thus,the present study aimed to investigate the influence of 2-O-β-D-glucopyranosyl-L-ascorbic acid(AA-2βG)isolated from the fruits of Lycium barbarum on preventing the high-fructose diet(HFrD)induced neuroinflammation in mice.It was found that AA-2βG prevented HFr D-induced cognitive deficits.AA-2βG also predominantly enhanced the gut barrier integrity,decreased lipopolysaccharide entry into the circulation,which subsequently countered the activation of glial cells and neuroinflammatory response.These beneficial effects were transmissible by horizontal fecal microbiome transplantation,transferring from AA-2βG fed mice to HFr D fed mice.Additionally,AA-2βG exerted neuroprotective effects involving the enrichment of Lactobacillus and Akkermansia,potentially beneficial intestinal bacteria.The present study provided the evidence that AA-2βG could improve indices of cognition and neuroinflammmation via modulating gut dybiosis and preventing leaky gut.As a potential functional food ingredient,AA-2βG may be applied to attenuate neuroinflammation associated with Western-style diets. | Wei Dong Yujia Peng Guijie Chen Zhiyong Xie Weiqi Xu Wangting Zhou Jia Mi Lu Lu Yi Sun Xiaoxiong Zeng Youlong Cao Yamei Yan | 2024 | Food Science and Human Wellness2024，13，1： | 0 |
