| 1 | Clinical and biochemical indexes from 2019-nCoV infected patients linked to viral loads and lung injury显示文摘The outbreak of the 2019-nCoV infection began in December 2019 in Wuhan,Hubei province,and rapidly spread to many provinces in China as well as other countries.Here we report the epidemiological,clinical,laboratory,and radiological characteristics,as well as potential biomarkers for predicting disease severity in 2019-nCoV-infected patients in Shenzhen,China.All 12 cases of the 2019-nCoV-infected patients developed pneumonia and half of them developed acute respiratory distress syndrome (ARDS).The most common laboratory abnormalities were hypoalbuminemia,lymphopenia,decreased percentage of lymphocytes (LYM) and neutrophils (NEU),elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH),and decreased CD8 count.The viral load of 2019-nCoV detected from patient respiratory tracts was positively linked to lung disease severity.ALB,LYM,LYM (%),LDH,NEU (%),and CRP were highly correlated to the acute lung injury.Age,viral load,lung injury score,and blood biochemistry indexes,albumin (ALB),CRP,LDH,LYM (%),LYM,and NEU (%),may be predictors of disease severity.Moreover,the Angiotensin Ⅱlevel in the plasma sample from 2019-nCoV infected patients was markedly elevated and linearly associated to viral load and lung injury.Our results suggest a number of potential diagnosis biomarkers and angiotensin receptor blocker (ARB) drugs for potential repurposing treatment of 2019-nCoV infection. | Yingxia Liu Yang Yang Cong Zhang Fengming Huang Fuxiang Wang Jing Yuan Zhaoqin Wang Jinxiu Li Jianming Li Cheng Feng Zheng Zhang Lifei Wang Ling Peng Li Chen Yuhao Qin Dandan Zhao Shuguang Tan Lu Yin Jun Xu Congzhao Zhou Chengyu Jiang Lei Liu | 2020 | Science China(Life Sciences)2020，63，3： | 157 |
| 2 | Elevated plasma levels of selective cytokines in COVID-19 patients reflect viral load and lung injury显示文摘A recent outbreak of pneumonia in Wuhan,China was found to be caused by a 2019 novel coronavirus(2019-nCoV or SARS-CoV-2 or HCoV-19).We previously reported the clinical features of 12 patients with2019-n Co V infections in Shenzhen,China.To further understand the pathogenesis of COVID-19 and find better ways to monitor and treat the disease caused by 2019-n Co V,we measured the levels of 48 cytokines in the blood plasma of those 12 COVID-19 patients.Thirty-eight out of the 48 measured cytokines in the plasma of 2019-n Co V-infected patients were significantly elevated compared to healthy individuals.Seventeen cytokines were linked to 2019-nCoV loads.Fifteen cytokines,namely M-CSF,IL-10,IFN-α2,IL-17,IL-4,IP-10,IL-7,IL-1 ra,G-CSF,IL-12,IFN-γ,IL-1α,IL-2,HGF and PDGF-BB,were strongly associated with the lung-injury Murray score and could be used to predict the disease severity of2019-n Co V infections by calculating the area under the curve of the receiver-operating characteristics.Our results suggest that 2019-nCoV infections trigger extensive changes in a wide array of cytokines,some of which could be potential biomarkers of disease severity of 2019-n Co V infections.These findings will likely improve our understanding of the immunopathologic mechanisms of this emerging disease.Our results also suggest that modulators of cytokine responses may play a therapeutic role in combating the disease once the functions of these elevated cytokines have been characterized. | Yingxia Liu Cong Zhang Fengming Huang Yang Yang Fuxiang Wang Jing Yuan Zheng Zhang Yuhao Qin Xiaoyun Li Dandan Zhao Shunwang Li Shuguang Tan Zhaoqin Wang Jinxiu Li Chenguang Shen Jianming Li Ling Peng Weibo Wu Mengli Cao Li Xing Zhixiang Xu Li Chen Congzhao Zhou William J Liu Lei Liu Chengyu Jiang | 2020 | National Science Review2020，7，6： | 6 |

| 4 | The norepinephrine transporter gene is associated with the retardation symptoms of major depressive disorder in the Han Chinese population显示文摘The norepinephrine transporter plays an important role in the pathophysiology and pharmacological treatment of major depressive disorder.Consequently,the norepinephrine transporter gene is an attractive candidate in major depressive disorder research.In the present study,we evaluated the depression symptoms of subjects with major depressive disorder,who were all from the North of China and of Han Chinese origin,using the Hamilton Depression Scale.We examined the rela-tionship between two single nucleotide polymorphisms in the norepinephrine transporter,rs2242446 and rs5569,and the retardation symptoms of major depressive disorder using quantitative trait testing with the UNPHASED program.rs5569 was associated with depressed mood,and the GG genotype may be a risk factor for this;rs2242446 was associated with work and interest,and the TT genotype may be a risk factor for loss of interest.Our findings suggest that rs2242446 and rs5569 in the norepinephrine transporter gene are associated with the retardation symptoms of depression in the Han Chinese population. | Xinrong Li Ning Sun Yong Xu Yanfang Wang Suping Li Qiaorong Du Juyi Peng Jinxiu Luo Kerang Zhang | 2012 | Neural Regeneration Research2012，7，25： | 3 |
| 5 | Cu^2+ reduces hemolytic activity of the antimicrobial peptide HMPI and enhances its trypsin resistance显示文摘Nowadays,drug-resistant microbes are becoming a serious clinical problem threatening people's health and life.An timicrobial peptides(AMPs)are believed to be pote ntial alter natives of con-ventional antibiotics to combat the threat of drug-resistant microbes.However,the susceptibility of AMPs toward proteases is one of the major problems limiting their clinical use.In the present study,we reported the effect of Cu^2+on the bioactivity of AMP HMPI.We found that the addition of Cu^2+could improve the protease resistance of AMP HMPI without affecting its bioactivity.Notably,after the binding of Cu^2+with HMPI,the hemolytic activity of HMPI was greatly decreased.In additi on,our results also demonstrated that the addition of Cu^2+in creased the production of reactive oxygen species in the fun gal cells,which may be a suppleme nt for the antifungal activity of HMPI.In con elusion,the introduction of Cu^2+may provide an inorganic strategy to improve the stability and decrease the hemolytic activity of AMP HMPI,while maintaining its antifungal activity. | Jinxiu Peng Yang Yang Ping Zhao Shuai Qiu Fengjing Jia Jiayi Wang Xiaolei Liang Ahmed Shabbir Chaudhry Peihan Xu Wenjin Yan Zhaoqing Xu Kairong Wang | 2020 | Acta Biochimica et Biophysica Sinica2020，52，6： | 2 |
| 6 | Laboratory Diagnosis and Monitoring the Viral Shedding of SARS-CoV-2 Infection显示文摘The worldwide epidemic of coronavirus disease 2019(COVID-19)is ongoing.Rapid and accurate detection of the causative virus SARSCoV-2 is vital for the treatment and control of COVID-19.In this study,the comparative sensitivity of different respiratory specimen types were retrospectively analyzed using 3,552 clinical samples from 410 COVID-19 patients confirmed by Guangdong CDC(Center for Disease Control and Prevention).Except for bronchoalveolar lavage fluid(BALF),the sputum possessed the highest positive rate(73.4%–87.5%),followed by nasal swabs(53.1%–85.3%)for both severe and mild cases during the first 14 days after illness onset(d.a.o.).Viral RNA could be detected in all BALF samples collected from the severe group within 14 d.a.o.and lasted up to 46 d.a.o.Moreover,although viral RNA was negative in the upper respiratory samples,it was also positive in BALF samples in most cases from the severe group during treatment.Notably,no viral RNA was detected in BALF samples from the mild group.Despite typical ground-glass opacity observed via computed tomographic scans,no viral RNA was detected in the first three or all upper respiratory tract specimens from some COVID-19 patients.In conclusion,sputum is most sensitive for routine laboratory diagnosis of COVID-19,followed by nasal swabs.Detection of viral RNA in BALF improves diagnostic accuracy in severe COVID-19 patients. | Yang Yang Minghui Yang Jing Yuan Fuxiang Wang Zhaoqin Wang Jinxiu Li Mingxia Zhang Jinli Wei Ling Peng Gary Wong Haixia Zheng Weibo Wu Chenguang Shen Mingfeng Liao Kai Feng Jianming Li Qianting Yang Juanjuan Zhao Lei Liu Yingxia Liu | 2020 | The Innovation2020，1，3： | 1 |
| 7 | Bioinspired iron porphyrins with appended poly-pyridine/amine units for boosted electrocatalytic CO_(2) reduction reaction显示文摘Developing highly efficient electrocatalysts for the CO_(2) reduction reaction(CO_(2)RR)has attracted increasing interest in the past decade.Herein,we report on the design and synthesis of Fe porphyrin 1 with an appended N,N-di(2-picolyl)ethylenediamine(DPEN)unit that boosts electrocatalytic activity for CO_(2)-to-CO conversion in acetonitrile with water as the proton source.By mimicking carbon monoxide dehydrogenase(CODH),1 has poly-pyridine/amine units located at the active site to form hydrogen-bonded water-containing networks that enable fast proton transfer.The protonated and positively charged DPEN unit can also stabilize CO_(2) reduction intermediates through electrostatic and hydrogen-bonding interactions.These factors make 1 a highly active electrocatalyst for the CO_(2)RR by achieving a TOFmax of 5.0×10^(4)s^(−1) with water providing the protons.These critical roles of the DPEN unit in the CO_(2)RR are further supported by theoretical studies.This work is significant to highlight the benefits of using molecular catalysts to elucidate structural effects. | Jinxiu Han Ni Wang Xialiang Li Haitao Lei Yabo Wang Hongbo Guo Xiaotong Jin Qingxin Zhang Xinyang Peng Xue-Peng Zhang Wei Zhang Ulf-Peter Apfel Rui Cao | 2022 | eScience2022，2，6： | 0 |
| 8 | Successful management of seven cases of critical COVID-19 with early noninvasive-invasive sequential ventilation algorithm and bundle pharmacotherapy显示文摘We report the clinical and laboratory findings and successful management of seven patients with critical coronavirus disease 2019(COVID-19)requiring mechanical ventilation(MV).The patients were diagnosed based on epidemiological history,clinical manifestations,and nucleic acid testing.Upon diagnosis with COVID-19 of critical severity,the patients were admitted to the intensive care unit,where they received early noninvasive-invasive sequential ventilation,early prone positioning,and bundle pharmacotherapy regimen,which consists of antiviral,anti-inflammation,immune-enhancing,and complication-prophylaxis medicines.The patients presented fever(n=7,100%),dry cough(n=3,42.9%),weakness(n=2,28.6%),chest tightness(n=1,14.3%),and/or muscle pain(n=1,14.3%).All patients had normal or lower than normal white blood cell count/lymphocyte count,and chest computed tomography scans showed bilateral patchy shadows or ground glass opacity in the lungs.Nucleic acid testing confirmed COVID-19 in all seven patients.The median MV duration and intensive care unit stay were 9.9 days(interquartile range,6.5-14.6 days;range,5-17 days)and 12.9 days(interquartile range,9.7-17.6 days;range,7-19 days),respectively.All seven patients were extubated,weaned off MV,transferred to the common ward,and discharged as of the writing of this report.Thus,we concluded that good outcomes for patients with critical COVID-19 can be achieved with early noninvasive-invasive sequential ventilation and bundle pharmacotherapy. | Mian Peng Xueyan Liu Jinxiu Li Di Ren Yongfeng Liu Xi Meng Yansi Lyu Ronglin Chen Baojun Yu Weixiong Zhong | 2020 | Frontiers of Medicine2020，14，5： | 0 |
