| 1 | Anti-SARS-CoV-2 activities in vitro of Shuanghuanglian preparations and bioactive ingredients显示文摘Human infection with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)causes coronavirus disease 2019(COVID-19)and there is no cure currently.The 3CL protease(3CLpro)is a highly conserved protease which is indispensable for CoVs replication,and is a promising target for development of broad-spectrum antiviral drugs.In this study we investigated the anti-SARS-CoV-2 potential of Shuanghuanglian preparation,a Chinese traditional patent medicine with a long history for treating respiratory tract infection in China.We showed that either the oral liquid of Shuanghuanglian,the lyophilized powder of Shuanghuanglian for injection or their bioactive components dose-dependently inhibited SARS-CoV-23CLpro as well as the replication of SARS-CoV-2 in Vero E6 cells.Baicalin and baicalein,two ingredients of Shuanghuanglian,were characterized as the first noncovalent,nonpeptidomimetic inhibitors of SARS-CoV-23CLpro and exhibited potent antiviral activities in a cell-based system.Remarkably,the binding mode of baicalein with SARS-CoV-23CLpro determined by X-ray protein crystallography was distinctly different from those of known 3CLpro inhibitors.Baicalein was productively ensconced in the core of the substrate-binding pocket by interacting with two catalytic residues,the crucial S1/S2 subsites and the oxyanion loop,acting as a“shield”in front of the catalytic dyad to effectively prevent substrate access to the catalytic dyad within the active site.Overall,this study provides an example for exploring the in vitro potency of Chinese traditional patent medicines and effectively identifying bioactive ingredients toward a specific target,and gains evidence supporting the in vivo studies of Shuanghuanglian oral liquid as well as two natural products for COVID-19 treatment. | Hai-xia Su Sheng Yao Wen-feng Zhao Min-jun Li Jia Liu Wei-juan Shang Hang Xie Chang-qiang Ke Hang-chen Hu Mei-na Gao Kun-qian Yu Hong Liu Jing-shan Shen Wei Tang Lei-ke Zhang Geng-fu Xiao Li Ni Dao-wen Wang Jian-ping Zuo Hua-liang Jiang Fang Bai Yan Wu Yang Ye Ye-chun Xu | 2020 | Acta Pharmacologica Sinica2020,41,9: | 32 |

| 3 | Activation of mTORC1 in subchondral bone preosteoblasts promotes osteoarthritis by stimulating bone sclerosis and secretion of CXCL12显示文摘Increasing evidences show that aberrant subchondral bone remodeling plays an important role in the development of osteoarthritis(OA).However,how subchondral bone formation is activated and the mechanism by which increased subchondral bone turnover promotes cartilage degeneration during OA remains unclear.Here,we show that the mechanistic target of rapamycin complex 1(mTORC1)pathway is activated in subchondral bone preosteoblasts(Osterix+)from OA patients and mice.Constitutive activation of mTORC1 in preosteoblasts by deletion of the mTORC1 upstream inhibitor,tuberous sclerosis 1,induced aberrant subchondral bone formation,and sclerosis with little-to-no effects on articular cartilage integrity,but accelerated posttraumatic OA development in mice.In contrast,inhibition of mTORC1 in preosteoblasts by disruption of Raptor(mTORC1-specific component)reduced subchondral bone formation and cartilage degeneration,and attenuated post-traumatic OA in mice.Mechanistically,mTORC1 activation promoted preosteoblast expansion and Cxcl12 secretion,which induced subchondral bone remodeling and cartilage degeneration during OA.A Cxcl12-neutralizing antibody reduced cartilage degeneration and alleviated OA in mice.Altogether,these findings demonstrate that mTORC1 activation in subchondral preosteoblasts is not sufficient to induce OA,but can induce aberrant subchondral bone formation and secrete of Cxcl12 to accelerate disease progression following surgical destabilization of the joint.Pharmaceutical inhibition of the pathway presents a promising therapeutic approach for OA treatment. | Chuangxin Lin Liangliang Liu Chun Zeng Zhong-Kai Cui Yuhui Chen Pinling Lai Hong Wang Yan Shao Haiyan Zhang Rongkai Zhang Chang Zhao Hang Fang Daozhang Cai Xiaochun Bai | 2019 | Bone Research2019,7,1: | 12 |

| 6 | Synthesis of fluorescent carbon quantum dots from aqua mesophase pitch and their photocatalytic degradation activity of organic dyes显示文摘A synthesis strategy of fluorescent carbon quantum dots(CQDs) with high quantum yield(QY) using aqua mesophase pitch(AMP) as the carbon source has been developed via the hydrothermal method in this study. The hydrothermal temperature and soaking time have important effects on the morphology and QY of CQDs. As-prepared CQDs at 120℃ holding for 24 h(CQDs-120-24) have the uniform size of about 2.8 nm, and the QY can reach 27.6%. The obtained CQDs are successfully modified with ammonia and thionyl chloride, respectively, and they exhibit an excellent photocatalytic performance on degrading rhodamine B(Rh B), methyl blue(MB) and indigo carmine(IC). Importantly, the degradation percentage of N-CQDs on Rh B under natural light for 4 h reaches 97% with the degradation rate constant of 0.02463 min^(-1) and it can maintain 93% after repetitively used 5 times. The results indicate that these as-prepared CQDs have the potential application in degrading organic dyes. | Youliang Cheng Mengsha Bai Jian Su Changqing Fang Hang Li Jing Chen Jieming Jiao | 2019 | Journal of Materials Science & Technology2019,35,8: | 6 |
| 7 | An App knock-in rat model for Alzheimer’s disease exhibiting Aβand tau pathologies,neuronal death and cognitive impairments显示文摘A major obstacle in Alzheimer’s disease(AD)research is the lack of predictive and translatable animal models that reflect disease progression and drug efficacy.Transgenic mice overexpressing amyloid precursor protein(App)gene manifest non-physiological and ectopic expression of APP and its fragments in the brain,which is not observed in AD patients.The App knock-in mice circumvented some of these problems,but they do not exhibit tau pathology and neuronal death.We have generated a rat model,with three familiar App mutations and humanized Aβsequence knocked into the rat App gene.Without altering the levels of full-length APP and other APP fragments,this model exhibits pathologies and disease progression resembling those in human patients:deposit of Aβplaques in relevant brain regions,microglia activation and gliosis,progressive synaptic degeneration and AD-relevant cognitive deficits.Interestingly,we have observed tau pathology,neuronal apoptosis and necroptosis and brain atrophy,phenotypes rarely seen in other APP models.This App knock-in rat model may serve as a useful tool for AD research,identifying new drug targets and biomarkers,and testing therapeutics. | Keliang Pang Richeng Jiang Wei Zhang Zhengyi Yang Lin-Lin Li Makoto Shimozawa Simone Tambaro Johanna Mayer Baogui Zhang Man Li Jiesi Wang Hang Liu Ailing Yang Xi Chen Jiazheng Liu Bengt Winblad Hua Han Tianzi Jiang Weiwen Wang Per Nilsson Wei Guo Bai Lu | 2022 | Cell Research2022,32,2: | 6 |
| 8 | Metabolic characteristics and nutrient utilization in high-feedefficiency pigs selected using different feed conversion ratio models显示文摘An understanding of the nutrient utilization characteristics of pigs with different feed efficiencies(FEs) will help us to develop new strategies to reduce the costs of pig production.In this study,we selected pigs with a range of FEs according to two feed conversion ratio models: the feed intake(FI) model,where pigs had the same average daily gains(ADGs) but different FIs,and the ADG model,where pigs had the same FIs but different ADGs.High-FE pigs had a higher abundance of short chain fatty acid(SCFA)-producing bacteria(Lachnospiraceae,Clostridiaceae1,and Coriobacteriaceae) in their caecum in the FI model,and low-FE pigs had a higher abundance of two families(BacteroidalesS247group and Peptococcaceae) and two genera(Anaerotruncus and CandidatusSoleaferrea) in both models.By contrast,high-FE pigs had more goblet cells and higher m RNA expression of insulin-like growth factor 1(IGF-1) in the FI model,and higher mRNA expression of occludin but lower expressions of adenosine monophosphate-activated protein kinase(AMPK)-α2 and peroxisome proliferator-activated receptor gamma coactivator 1 alpha(PGC1α) in the ADG model.These findings suggest that the presence of SCFA-producing bacteria in the caecum and increased muscular growth may contribute to the high FE of low-FI pigs,while improved intestinal functions and decreased mitochondrial activity in the skeletal muscle are related to the high FE of high-ADG pigs. | Beibei He Tiantian Li Wei Wang Hang Gao Yu Bai Shuai Zhang Jianjun Zang Defa Li Junjun Wang | 2019 | Science China(Life Sciences)2019,62,7: | 5 |

| 10 | Effect of electroacpuncture of Neiguan(PC 6)and Tianquan(PC 2)on skin temperature,blood perfusion,and adrenoceptor response in rats with acute myocardial ischemia显示文摘OBJECTIVE: To investigate the effect of electroacupuncture(EA) of acupoints Neiguan(PC 6) and Tianquan(PC 2) on the skin temperature, blood perfusion, and alpha1-and beta2-adrenoreceptor(α1-AR and β2-AR) protein and m RNA level in rats with acute myocardial ischemia.METHODS: Thirty male adult Wistar rats [(230 ±20) g] were randomly assigned into five groups(n = 6 each): a control group, sham operation group, model group, model group treated with EA at low frequency(L-EA, 2 Hz, 1 m A) and model group treated with EA at high frequency(H-EA, 100 Hz, 1 m A). The rat model was prepared by ligating the left anterior descending coronary artery. Electroacupuncture was performed at the left Neiguan(PC 6) for 20 min daily for 3 d. After the 3 rd time of the treatment, measurements of skin blood perfusion and temperature in Neiguan(PC 6) and Tianquan(PC 2) in all groups were made by laser speckle contrast imaging and infrared thermal image instrument. Real-time PCR and ELISA were used to measure m RNA level and protein level of α1-AR andβ2-AR in the skin tissues of Neiguan(PC 6) and Tianquan(PC 2), respectively. Serum levels of c Tn T and electrocardiogram were used to identify the state of myocardium.RESULTS: In the group receiving electroacupunture at Neiguan(PC 6), compared with control group,the skin temperature, blood perfusion, and β2-AR m RNA and protein level of model group significantly decreased(P < 0.05), α1-AR m RNA and protein level of model group significantly increased(P < 0.05);compared with model group, the skin temperature,blood perfusion, and β2-AR m RNA and protein level of L-EA significantly increased(P < 0.05), α1-AR m RNA and protein level of L-EA and H-EA significantly decreased(P < 0.05). The same trend has taken place in the former four groups of the Tianquan(PC 2).CONCLUSION: Low-or high-frequency electroacupuncture can improve the skin temperature and blood perfusion which may be induced by decreasingthelevelofα1-ARandincreasingthelevelofβ2-AR of the Neiguan(PC 6) and Tianquan(PC 2) in the rat with acute myocaidial ischemia. | Wang Dan Ji Bo Zhao Guozhen Yan Mingna Bai Hongxin Sun Xiaomin Dai Jian Lu Yawen Liu Yitian You Min Wu Jiaojuan Ge Yunpeng Su Hang Cheng Kai | 2017 | Journal of Traditional Chinese Medicine2017,37,6: | 3 |
