1Identification of a novel coronavirus causing severe pneumonia in human:a descriptive study显示文摘Background:Human infections with zoonotic coronaviruses(CoVs),including severe acute respiratory syndrome(SARS)-CoV and Middle East respiratory syndrome(MERS)-CoV,have raised great public health concern globally.Here,we report a novel batorigin CoV causing severe and fatal pneumonia in humans.Methods:We collected clinical data and bronchoalveolar lavage(BAL)specimens from five patients with severe pneumonia from Wuhan Jinyintan Hospital,Hubei province,China.Nucleic acids of the BAL were extracted and subjected to next-generation sequencing.Virus isolation was carried out,and maximum-likelihood phylogenetic trees were constructed.Results:Five patients hospitalized from December 18 to December 29,2019 presented with fever,cough,and dyspnea accompanied by complications of acute respiratory distress syndrome.Chest radiography revealed diffuse opacities and consolidation.One of these patients died.Sequence results revealed the presence of a previously unknownβ-CoV strain in all five patients,with 99.8%to 99.9%nucleotide identities among the isolates.These isolates showed 79.0%nucleotide identity with the sequence of SARS-CoV(GenBank NC_004718)and 51.8%identity with the sequence of MERS-CoV(GenBank NC_019843).The virus is phylogenetically closest to a bat SARS-like CoV(SL-ZC45,GenBank MG772933)with 87.6%to 87.7%nucleotide identity,but is in a separate clade.Moreover,these viruses have a single intact open reading frame gene 8,as a further indicator of bat-origin CoVs.However,the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV,indicating that these viruses might use the same receptor.Conclusion:A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans.Li-Li Ren Ye-Ming Wang Zhi-Qiang Wu Zi-Chun Xiang Li Guo Teng Xu Yong-Zhong Jiang Yan Xiong Yong-Jun Li Xing-Wang Li Hui Li Guo-Hui Fan Xiao-Ying Gu Yan Xiao Hong Gao Jiu-Yang Xu Fan Yang Xin-Ming Wang Chao Wu Lan Chen Yi-Wei Liu Bo Liu Jian Yang Xiao-Rui Wang Jie Dong Li Li Chao-Lin Huang Jian-Ping Zhao Yi Hu Zhen-Shun Cheng Un-Lin Liu Zhao-Hui Qian Chuan Qin Qi Jin Bin Cao Jian-Wei Wang 2020Chinese Medical Journal2020,,9:99
2Gd-EOB-DTPA-enhanced magnetic resonance imaging for focal liver lesions in Chinese patients:a multicenter,open-label,phase Ⅲ study显示文摘BACKGROUND:Contrast agents help to improve visibility in magnetic resonance(MR)imaging.However,owing to the large interstitial spaces of the liver,there is a reduction in the natural contrast gradient between lesions and healthy tissue.This study was undertaken to evaluate the efficacy and safety of the liverspecific MR imaging contrast agent gadoxetate disodium(GdEOB-DTPA)in Chinese patients.METHODS:This was a single-arm,open-label,multicenter study in patients with known or suspected focal liver lesions referred for contrast-enhanced MR imaging.MR imaging was performed in 234 patients before and after a single intravenous bolus of Gd-EOB-DTPA(0.025 mmol/kg body weight).Images were evaluated by clinical study investigators and three independent,blinded radiologists.The primary efficacy endpoint was sensitivity in lesion detection.RESULTS:Gd-EOB-DTPA improved sensitivity in lesion detection by 9.46%compared with pre-contrast imaging for the average of the three blinded readers(94.78%vs 85.32%for Gd-EOB-DTPA vs pre-contrast,respectively).Improvements in detection were more pronounced in lesions less than 1cm.Gd-EOB-DTPA improved diagnostic accuracy in lesion classification.CONCLUSIONS:This open-label study demonstrated that Gd-EOB-DTPA improves diagnostic sensitivity in liver lesions,particularly in those smaller than 1 cm.Gd-EOB-DTPA also significantly improves the diagnostic accuracy in lesion classification,and furthermore,Gd-EOB-DTPA is safe in Chinese patients with liver lesions.Meng-Su Zeng Hui-Yi Ye Liang Guo Wei-Jun Peng Jian-Ping Lu Gao-Jun Teng Josy Breuer Yi Huan Ping Li Jian-Rong Xu Chang-Hong Liang 2013Hepatobiliary & Pancreatic Diseases International2013,12,6:31

5Hanning self-convolution window and its application to harmonic analysis显示文摘The Hanning self-convolution window (HSCW) is proposed in this paper. And the phase difference correction algorithm based on the discrete spectrum and the HSCW is given. The HSCW has a low peak side lobe level, a high side lobe roll-off rate, and a simple spectrum representation. Hence, leakage errors and harmonic interferences can be considerably reduced by weighting samples with the HSCW, the parameter estimation by the HSCW-based phase difference correction algorithm is free of solving high order equations, and the overall method can be easily implemented in embedded systems. Simulation and application results show that the HSCW-based phase difference correction algorithm can suppress the impacts of fundamental frequency fluctuation and white noise on harmonic parameter estimation, and the HSCW is advantageous over existing combined cosine windows in terms of harmonic analysis performance.WEN He TENG ZhaoSheng GUO SiYu WANG JingXun YANG BuMing WANG Yi CHEN Tao 2009Science China(Technological Sciences)2009,52,2:15

8Effects of Chinese herbal medicine Yiqi Huaju Formula on hypertensive patients with metabolic syndrome:a randomized,placebo-controlled trial显示文摘BACKGROUND:Patients with hypertension coupled with metabolic syndrome(MetS) are among the high risk population in cardiovascular and cerebrovascular diseases.To reduce the prevalence of cardiovascular and cerebrovascular diseases,it is essential to appropriately control blood pressure together with other cardiovascular risk factors. OBJECTIVE:The current study was designed to investigate the therapeutic effects on blood pressure,blood pressure variability and other cardiovascular risk factors by giving Yiqi Huaju Formula,a compound traditional Chinese herbal medicine,in addition to routine treatment to hypertensive patients coupled with MetS. DESIGN,SETTING,PARTICIPANTS AND INTERVENTIONS:A total of 43 patients with hypertension coupled with MetS were recruited into this study.The enrolled patients were randomly divided into the Chinese herbal formula group(anti-hypertensive drugs plus Yiqi Huaju Formula,CHF) and the control group(anti-hypertensive drugs plus placebo).The CHF group enrolled 22 patients while the control group received 21 cases.Treatments were given for 12 weeks in both groups. MAIN OUTCOME MEASURES:Parameters examined include 24-hour ambulatory blood pressure monitoring,body mass index,waist circumference,waist-to-hip ratio,homeostatic model assessment for insulin resistance(HOMA-IR),fasting glycosylated hemoglobin(HbA1c),fasting plasma glucose,2-hour postprandial plasma glucose(PPG),fasting plasma insulin,serum lipid,etc. RESULTS:Compared with the control group,the CHF group had significant improvement (PO.01) in anthropometric parameters,FPG,HOMA-IR,blood pressure amplitude,blood pressure variability and blood pressure load. CONCLUSION:This study showed that integrated traditional Chinese and Western medicine treatment can achieve better results in controlling blood pressure as well as other cardiovascular risk factors.The mechanism of controlling of blood pressure may be associated with the improvement of insulin sensitivity due to the Yiqi Huaju intervention.

9Design and application of structural health monitoring system in long-span cable-membrane structure显示文摘Cable-membrane structures have small rigidity and are highly sensitive to wind. Structural health monitoring is necessary to ensure the serviceability and safety of the structure. In this research, the design method of a structural health monitoring system is using the characteristics of a cable-membrane structure. Taking the Yueyang Sanhe Airport Terminal as an example, a finite element model is established to determine the critical structural components. Next, the engineering requirements and the framework of the monitoring system are studied based on the results of numerical analysis. The specific implementation of the structural health monitoring is then carried out, which includes sensor selection, installation and wiring. The proposed framework is successfully applied to the monitoring system for the Yueyang Airport terminal building, and the synchronous acquisition of fiber Bragg grating and acceleration sensor signals is implemented in an innovative way. The successful implementation and operation of structural health monitoring will help to guarantee the safety of the cablemembrane structure during its service life.Tang Teng Yang Dong-Hui Wang Lei Zhang Jian-Ren Yi Ting-Hua 2019Earthquake Engineering and Engineering Vibration2019,18,2:8
10Effects of Chinese herbal medicine Yiqi Huaju Qingli Formula in metabolic syndrome patients with microalbuminuria:a randomized placebo-controlled trial显示文摘BACKGROUND:Microalbuminuria(MAU) is a key component of metabolic syndrome(MetS) and is an early sign of diabetic nephropathy as well.Although routine Western medicine treatments are given to MetS patients to control high blood pressure,hyperglycemia and dyslipidemia,some patients still experience progressive renal lesions and it is necessary to modify and improve the treatment strategy for MetS patients. OBJECTIVE:To investigate the efficacy of Yiqi Huaju Qingli Herb Formula,a compound traditional Chinese herbal medicine,in MetS patients with MAU when it is combined with routine Western medicine treatment. DESIGN,SETTING,PARTICIPANTS AND INTERVENTIONS:Sixty patients with MetS were randomized into the Chinese herbal formula group(CHF,Yiqi Huaju Qingli formula treatment in combination with Western medicine) and control group(placebo in combination with Western medicine).All treatments were administered for 12 weeks. MAIN OUTCOME MEASURES:Urinary microalbumin(MA),urinary albumin-to-creatinine ratio (UACR),24-hour total urine protein(24-hTP),body mass index(BMI),waist circumference (WC),waist-to-hip ratio(WHR),fasting plasma glucose(FPG),2-hour postprandial plasma glucose(2-hPPG),glycosylated hemoglobin(HbA1c),homeostasis model assessment for insulin resistance(HOMA-IR),blood lipid profile and blood pressure were observed. RESULTS:Compared with the control group,CHF treatment significantly decreased BMI (P<0.05),WC(P<0.01) and WHR(P<0.01).Both groups had significant decreases in FPG, 2-hPPG,HbA1c,HOMA-IR,MA,and UACR,with CHF treatment showing better effects on these parameters compared with the control treatment(P<0.05).Both treatments significantly reduced the levels of total cholesterol,low-density lipoprotein cholesterol and triacylglycerol(TAG),and a greater reduction in TAG was observed with CHF treatment(P<0.05).The level of high-density lipoprotein cholesterol did not change in the control group after treatment(P>0.05),whereas it significantly increased with CHF treatment(P<0.01).Compared with before the treatment,significant decreases in systolic blood pressure,diastolic blood pressure and mean arterial blood pressure were observed in both groups(P<0.01).However,there was no significant difference between the two groups(P>0.05). CONCLUSION:Combined treatment of Yiqi Huaju Qingli Formula and Western medicine significantly alleviated MAU,which may correlate with the improvement of insulin sensitivity and glucose and lipid metabolism. TRIAL REGISTRATION IDENTIFIER:This trial was registered in the Chinese Clinical Trial Registry with the identifier ChiCTR-TRC-11001633.Tian-zhan Wang Yu Chen Yan-ming He Xiao-dong Fu Yi Wang Yan-qiu Xu Hong-jie Yang Hong-li Xue Yi Liu Xiao-tao Feng Teng Zhang Wen-jian Wang 2013Journal of Integrative Medicine2013,11,3:8
11Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 2020Biomedical and Environmental Sciences2020,33,12:8
12Allelochemical p-hydroxybenzoic acid inhibits root growth via regulating ROS accumulation in cucumber(Cucumis sativus L.)显示文摘Allelopathy is prevalent in agricultural ecosystems and mediated by plant-derived secondary metabolites(allelochemicals).Allelochemicals are released by donor plants and affect the root growth and development of receptor plants.Allelopathy is responsible for the continuous cropping obstacles in cucumber(Cucumis sativus L.).p-Hydroxybenzoic acid(pHBA),an autotoxin from root exudates of cucumber,has been proposed to be an important allelopathic chemical.However,the molecular mechanism by which pHBA affect root growth and development in cucumber is unknown.Here,we found that pHBA treatment suppressed root growth of cucumber by reducing the meristem activity and cell length.This root growth defect is caused by reduced reactive oxygen species(ROS)accumulation in root tips.After pHBA treatment,the expression levels of several ROS-scavenging-related genes were increased,including peroxidase(POD),catalase(CAT)and metallothionein(MT).Moreover,exogenously application of salicylhydroxamate(SHAM),a peroxidase inhibitor,can partially restore the pHBA treatment induced root growth inhibition.Furthermore,we found that there is natural variation for the inhibitory effect of pHBA on root growth.We also showed that pHBA treatment could maintain higher level of ROS accumulated in the pHBA less sensitive cucumber than that in the pHBA-sensitive cucumber.These results suggest that pHBA inhibits root growth by reducing root tip ROS level in cucumber.HUANG Cheng-zhen XU Lei Sun Jin-jing ZHANG Zhong-hua FU Mei-lan TENG Hui-ying YI Ke-ke 2020Journal of Integrative Agriculture2020,19,2:8

14Immunotherapy in liver transplantation for hepatocellular carcinoma:Pros and cons显示文摘Liver transplantation(LT)has emerged as a curative strategy for hepatocellular carcinoma(HCC),but contributes to a higher predisposition to HCC recurrence in the immunosuppression context,especially for tumors beyond the Milan criteria.Although immunotherapy has dramatically improved survival for immunocompetent patients and has become the standard of care for a variety of tumors,including HCC,it is mainly used outside the scope of organ transplantation owing to potentially fatal allograft rejection.Nevertheless,accumulative evidence has expanded the therapeutic paradigms of immunotherapy for HCC,from downstaging or bridging management in the pretransplant setting to the salvage or adjuvant strategy in the posttransplant setting.Generally,immunotherapy mainly includes immune checkpoint inhibitors(ICIs),adoptive cell transfer(ACT)and vaccine therapy.ICIs,followed by ACT,have been most investigated in LT,with some promising results.Because of the complex tumor microenvironment and immunoreactivity when immunosuppressants are combined with immunotherapy,it is difficult to reach formulations for immunosuppressant adjustment and the optimal selection of immunotherapy as well as patients.In addition,the absence of effective biomarkers for identifying rejection and tumor response is still an unresolved barrier to successful clinical immunotherapy applications for LT.In this review,we comprehensively summarize the available evidence of immunotherapy used in LT that is specific to HCC.Moreover,we discuss clinically concerning issues regarding the concurrent goals of graft protection and antitumor response.Yi Luo Fei Teng Hong Fu Guo-Shan Ding 2022World Journal of Gastrointestinal Oncology2022,14,1:7
15Energy Saving Cooperative Communication over Fading Channels with Relay Selection and Power Control显示文摘In order to save energy and make more efficient use of wireless channel, this article puts forward an energy saving cooperative relaying scheme which actuates the cooperative transmission only when the feedback from the destination indicates failure of the direct transmission. The proposed scheme selects the optimal relay and its corresponding transmission power in each time slot based on channel condition and residual energy with the objective of minimizing energy consumption and extending network lifetime. In the study, the finite-state Markov channel model is used to characterize the correlation structure of channel fading in wireless networks, and the procedure of relay selection and transmission power decision is formulated as a Markov decision process. Numerical and simulation results show that the proposed scheme consumes less energy and prolongs the network lifetime.Wei Yifei Teng Yinglei Wang Li Song Mei Man Yi 2012China Communications2012,9,6:7
16Colorectal cancer burden,trends and risk factors in China:A review and comparison with the United States显示文摘Objective:China and the United States(the U.S.)have the heaviest colorectal cancer(CRC)burden with considerable variations in temporal trends.This study aims to analyze the temporal patterns of CRC burden and its risk factors in China and the U.S.across the past three decades.Methods:Data were extracted from the Global Burden of Disease(GBD)Study in 2019,including cases,deaths,disability-adjusted life-years(DALYs),age-standardized rate(ASR),and summary exposure value(SEV)of CRC in China and the U.S.between 1990 and 2019.Annual average percentage changes(AAPCs)of CRC burden were calculated using the Joinpoint regression model.The mortality in CRC attributable to potential risk factors was characterized by countries,gender,and age groups.Results:In 2019,there were 607,900 and 227,241 CRC cases,and 261,777 and 84,026 CRC deaths in China and the U.S.,respectively.The age-standardized incidence rate(ASIR)was 30.55 per 100,000 in China and 41.86 per100,000 in the U.S.,and the age-standardized mortality rate(ASMR)was 13.86 per 100,000 in China and 14.77 per100,000 in the U.S.CRC incidence,mortality,and DALY rate in the U.S.showed downward trends in the past three decades(AAPC=-0.47,-1.06,and-0.88,respectively),while upward trends were observed in China(AAPC=3.11,1.05,and 0.91,respectively).Among the cause of CRC,the leading risk factor contributing to CRC death was low milk in China and smoking in the U.S.,respectively.Conclusions:From 1990 to 2019,the burden of CRC in China increased dramatically,particularly for males and middle-aged and elderly people.The management of the major risk factors associated with the high burden of CRC should be enhanced.Qianru Li Hongliang Wu Maomao Cao He Li Siyi He Fan Yang Xinxin Yan Shaoli Zhang Yi Teng Changfa Xia Ji Peng Wanqing Chen 2022Chinese Journal of Cancer Research2022,34,5:6

18Diabetes recurrence after metabolic surgeries correlates with re-impaired insulin sensitivity rather than beta-cell function显示文摘AIM To investigate factors causing diabetes recurrence after sleeve gastrectomy(SG)and duodenal-jejunal bypass(DJB).METHODS SG and DJB were performed on rats with diabetes induced by high-fat diet(HFD)and streptozotocin(STZ).HFD was used to induce diabetes recurrence at 4 wk postoperatively.Body weight,oral glucose tolerance test,homeostatic model assessment of insulin resistance(HOMA-IR),insulin signaling[IR,insulin receptor substrate(IRS 1,IRS2,phosphatidylinositol3-kinase and AKT in liver and skeletal muscle],oral glucose stimulated insulin secretion,beta-cell morphology(mass,apoptosis and insulin secretion),glucagon-like peptide(GLP)-1,PYY and ghrelin were compared among SG rats with common low-fat diet(SG-LFD),SG with HFD(SG-HFD),DJB rats with LFD(DJB-LFD),DJB with HFD(DJB-HFD)and shamoperation with LFD(Sham)at targeted postoperative times.RESULTS SG and DJB resulted in significant improvement in glucose tolerance,lower HOMA-IR,up-regulated hepatic and muscular insulin signaling,higher levels of oral glucose-stimulated insulin secretion,bigger betacell mass,higher immunofluorescence intensity of insulin,fewer transferase-mediated d UTP-biotin 3’nick end-labeling(TUNEL)-positive beta cells and higher postprandial GLP-1 and PYY levels than in the Sham group.The improvement in glucose tolerance was reversed at 12 wk postoperatively.Compared with the SG-LFD and DJB-LFD groups,the SG-HFD and DJB-HFD groups showed higher HOMA-IR,down-regulated hepatic and muscular insulin signaling,and more TUNEL-positive beta cells.No significant difference was detected between HFD and LFD groups for body weight,glucose-stimulated insulin secretion,betacell mass,immunofluorescence intensity of insulin,and postprandial GLP-1 and PYY levels.Fasting serum ghrelin decreased in SG groups,and there was no difference between HFD-SG and LFD-SG groups.CONCLUSION HFD reverses the improvement in glucose homeostasis after SG and DJB.Diabetes recurrence may correlate with re-impaired insulin sensitivity,but not with alterations of beta-cell function and body weight.Teng Liu Ming-Wei Zhong Yi Liu Dong Sun Meng Wei Xin Huang Yu-Gang Cheng Qun-Zheng Wu Dong Wu Xiao-Qian Zhang Ke-Xin Wang San-Yuan Hu Shao-Zhuang Liu 2017World Journal of Gastroenterology2017,23,19:5
19Surface plasmonic effect and scattering effect of Au nanorods on the performance of polymer bulk heterojunction solar cells显示文摘The surface plasmonic effect and scattering effect of gold nanorods(AuNRs) on the performance of bulk heterojunction photovoltaic devices based on the blend of polythiophene and fullerene are investigated.AuNRs enhance the excitation since the plasmonic effect increases the electric field,mainly in the area near the interface between the active layer and AuNRs.The results show that the incident photo-to-electron conversion efficiency(IPCE) obviously increases for the device with a layer of gold nanorods,resulting from the plasmonic effect of AuNRs in the range of 500-670 nm and the scattering effect in the range of 370-410 nm.The power conversion efficiency(PCE) is increased by 7.6% due to the near field effect of the localized surface plasmons(LSP) of AuNRs and the scattering effect.The short circuit current density is also increased by 9.1% owing to the introduction of AuNRs.However,AuNRs can cause a little deterioration in open circuit voltage.FANG Yi HOU YanBing LOU ZhiDong TENG Feng TANG AiWei HU YuFeng 2013Science China(Technological Sciences)2013,56,8:4
20Extraction and Anti-diabetic Activity on Alloxan-induced Diabetic Mice of Polysaccharides from Huidouba显示文摘The polysaccharide extracted from Huidouba(PEH) exihibited a significant anti-diabetic activity. The polysaccharide contained glucose, mannose and galactose in a content ratio of 1.00:0.34:0.32. After administration with 50―200 mg/kg body weight of PEH to type Ⅱ diabetic mice induced by alloxan for four weeks, the blood glucose level of mice was decreased significantly. Moreover, the SOD activity increased at the same time(p<0.01). PEH showed a significant anti-diabetic and anti-oxidation activity. In addition, PEH affected the BUN and ALT levels(p<0.05), which are important characteristics of diabetes mellitus. Through this work, PEH should be a potential anti-diabetic drug in the future.LIU Yan CHEN Zhao-jie LIANG Yong-tao CUI Li-yang ZHENG Dan GUO Wei-liang REN Xiao-dong Wu Yi TENG Li-rong 2009Chemical Research in Chinese Universities2009,25,5:4
