1A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV) infected pneumonia(standard version)显示文摘In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province;and then named '2019 novel coronavirus(2019-nCoV)' by the World Health Organization(WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world’s attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development;we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control(including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV.Ying-Hui Jin Lin Cai Zhen-Shun Cheng Hong Cheng Tong Deng Yi-Pin Fan Cheng Fang Di Huang Lu-Qi Huang Qiao Huang Yong Han Bo Hu Fen Hu Bing-Hui Li Yi-Rong Li Ke Liang Li-Kai Lin Li-Sha Luo Jing Ma Lin-Lu Ma Zhi-Yong Peng Yun-Bao Pan Zhen-Yu Pan Xue-Qun Ren Hui-Min Sun Ying Wang Yun-Yun Wang Hong Weng Chao-Jie Wei Dong-Fang Wu Jian Xia Yong Xiong Hai-Bo Xu Xiao-Mei Yao Yu-Feng Yuan Tai-Sheng Ye Xiao-Chun Zhang Ying-Wen Zhang Yin-Gao Zhang Hua-Min Zhang Yan Zhao Ming-Juan Zhao Hao Zi Xian-Tao Zeng Yong-Yan Wang Xing-Huan Wang 2020Military Medical Research2020,7,1:161
2Prevalence of Atrial Fibrillation in China and Its Risk Factors显示文摘Objective To study the prevalence of atrial fibrillation(AF)and the relation with its risk factors in China.Methods A total of 19 363 participants(8635 males and 10 728 females) aged ≥35 years in geographically dispersed urban and rural regions of China were included in this cross-sectional survey.All participants received questionnaire,physical and blood examination.Echocardiography were performed for AF patients found in the survey.Results Of the 19 363 participants,199 were diagnosed with AF.The estimated age-standardized prevalence of AF was 0.78% in men and 0.76% in women.The prevalence of AF in participants aged <60 years was 0.41% in men and 0.43% in women,and was 1.83% in both men and women aged ≥60 years.About 19.0% of males and 30.9% of females with AF were diagnosed with valve disease.Age-and sex-adjusted multivariable logistic regression analysis revealed that myocardial infarction,left ventricular hypertrophy(LVH),obesity,and alcohol consumption were associated with a increased risk of AF(P<0.05).Conclusion The age standardized prevalence of AF is 0.77% in the participants enrolled in the present study.The number of AF cases aged ≥35 years is 5.26 million according to 2010 Chinese Census.Most risk factors for AF,identified mainly in Western countries,are also detected in China.LI Ying WU Yang Feng CHEN Ke Ping LI Xian ZHANG Xing XIE Gao Qiang WANG Fang Zheng ZHANG Shu 2013Biomedical and Environmental Sciences2013,26,9:48
3New vacuum solar telescope and observations with high resolution显示文摘The New Vacuum Solar Telescope(NVST) is a one meter vacuum solar telescope that aims to observe fine structures on the Sun. The main goals of NVST are high resolution imaging and spectral observations, including measurements of the solar magnetic field. NVST is the primary ground-based facility used by the Chinese solar research community in this solar cycle. It is located by Fuxian Lake in southwest China, where the seeing is good enough to perform high resolution observations. We first introduce the general conditions at the Fuxian Solar Observatory and the primary science cases of NVST. Then, the basic structures of this telescope and instruments are described in detail. Finally, some typical high resolution data of the solar photosphere and chromosphere are also shown.Zhong Liu Jun Xu Bo-Zhong Gu Sen Wang Jian-Qi You Long-Xiang Shen Ru-Wei Lu Zhen-Yu Jin Lin-Fei Chen Ke Lou Zhi Li Guang-Qian Liu Zhi Xu Chang-Hui Rao Qi-Qian Hu Ru-Feng Li Hao-Wen Fu Feng Wang Men-Xian Bao Ming-Chan Wu Bo-Rong Zhang 2014Research in Astronomy and Astrophysics2014,14,6:37
4Astragalus polysaccharide reduces hepatic endoplasmic reticulum stress and restores glucose homeostasis in a diabetic KKAy mouse model显示文摘Aim:To examine the potential effects of Astragalus polysaccharide (APS) onhepatic endoplasmic reticulum (ER) stress in vivo and in vitro and its link withhypoglycemia activity,thus establishing the mechanism underlying the hypogly-cemic action of APS.Methods:The obese and type 2 diabetic KKAy mousemodel,which is the yellow offspring of the KK mice expressed A^y gene (700mg·kg^(-1)·d^(-1),8 weeks) and a high glucose-induced HepG2 cell model (200 μg/mL,24 h)were treated with APS.The oral glucose tolerance test was measured to reflexinsulin sensitivity with the calculated homeostasis model assessment (HOMA-IR) index.XBP 1 (XhoI site-binding protein 1) transcription and splicing,an indica-tor of ER stress,was analyzed by RT-PCR and real-time PCR.The expression andactivation of glycogen synthase kinase 3 beta (GSK3β),an insulin signaling protein,was measured by Western blotting.Results:APS can alleviate ER stress in cul-tured cells in vivo.The hyperglycemia status,systemic insulin sensitivity,fattyliver disease,and insulin action in the liver of diabetic mice were partly normalizedor improved in response to APS administration.Conclusion:Our results indicatethat APS enables insulin-sensitizing and hypoglycemic activity at least in part byenhancing the adaptive capacity of the ER,which can further promote insulinsignal transduction.Thus,APS has promising application in the treatment of type2 diabetes.Xian-qing MAO Yong WU Ke WU Ming LIU Jing-fang ZHANG Feng ZOU Jing-ping OU-YANG 2007Acta Pharmacologica Sinica2007,28,12:32
5Anti-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 2020Acta Pharmacologica Sinica2020,41,9:32

7A national report from China Liver Transplant Registry: steroid avoidance after liver transplantation for hepatocellular carcinoma显示文摘Objective:We aimed to evaluate the efficacy and safety of steroid-free immunosuppression after liver transplantation(LT)for hepatocellular carcinoma(HCC).Methods:We retrospectively analyzed HCC recipients without steroids after LT(SF group,n=368)based on the China Liver Transplant Registry(CLTR)database.These recipients were matched 1:2 with patients using steroids(S group,n=736)for the same period after LT for HCC,according to propensity scores.Results:Multivariate analysis indicates that recipients with younger age[odds ratio(OR),1.053;P=0.011],preoperative hepatitis B virus(HBV)DNA≥1,000 copies/mL(OR,2.597;P=0.004)and beyond Milan criteria(OR,4.255;P<0.001)were identified as the risk factors associated with tumor recurrence in steroid avoidance recipients after LT.The patients fulfilling the Milan criteria in the SF group presented higher overall and tumor-free survival rates than those in the S group(P<0.05).Multivariate analysis revealed that recipient beyond Milan criteria was an independent prognostic factor for overall survival(OR,1.690;P<0.001)and tumor-free survival(OR,2.066;P<0.001).The incidences of new-onset diabetes mellitus(21.20% vs.33.29%,P<0.001),new-onset hypertension(10.05%vs.18.61%,P<0.001)and hyperlipidemia(4.08% vs.7.20%,P=0.042)were significantly lower in the SF group.Conclusions:Steroid-free immunosuppression could be safe and feasible for HBV-related HCC patients in LT.Age,HBV DNA level and Milan criteria maybe risk factors associated with tumor recurrence in steroid avoidance recipients.Recipient beyond Milan criteria was an independent prognostic factor and recipient fulfilling Milan criteria can benefit the most from steroid-free immunosuppression.Qiang Wei Feng Gao Runzhou Zhuang Qi Ling Qinghong Ke Jian Wu Tian Shen Mangli Zhang Min Zhang Xiao Xu Shusen Zheng 2017Chinese Journal of Cancer Research2017,29,5:25
8Acute kidney injury in acute-on-chronic liver failure is different from in decompensated cirrhosis显示文摘AIM To evaluate the differences in acute kidney injury(AKI) between acute-on-chronic liver failure(ACLF) and decompensated cirrhosis(DC) patients. METHODS During the period from December 2015 to July 2017, 280 patients with hepatitis B virus(HBV)-related ACLF(HBV-ACLF) and 132 patients with HBV-related DC(HBV-DC) who were admitted to our center were recruited consecutively into an observational study. Urine specimens were collected from all subjects and the levels of five urinary tubular injury biomarkers were detected,including neutrophil gelatinase-associated lipocalin(NGAL), interleukin-18(IL-18), liver-type fatty acid binding protein(L-FABP), cystatin C(CysC), and kidney injury molecule-1(KIM-1). Simultaneously, the patient demographics, occurrence and progression of AKI, and response to terlipressin therapy were recorded. All patients were followed up for 3 mo or until death after enrollment. RESULTS AKI occurred in 71 and 28 of HBV-ACLF and HBV-DC patients, respectively(25.4% vs 21.2%, P = 0.358). Among all patients, the levels of four urinary biomarkers(NGAL, CysC, L-FABP, IL-18) were significantly elevated in patients with HBV-ACLF and AKI(ACLF-AKI), compared with that in patients with HBV-DC and AKI(DC-AKI) or those without AKI. There was a higher proportion of patients with AKI progression in ACLF-AKI patients than in DC-AKI patients(49.3% vs 17.9%, P = 0.013). Fortythree patients with ACLF-AKI and 19 patients with DC-AKI were treated with terlipressin. The response rate of ACLFAKI patients was significantly lower than that of patients with DC-AKI(32.6% vs 57.9%, P = 0.018). Furthermore, patients with ACLF-AKI had the lowest 90 d survival rates among all groups(P < 0.001).CONCLUSION AKI in ACLF patients is more likely associated with structural kidney injury, and is more progressive, with a poorer response to terlipressin treatment and a worse prognosis than that in DC patients.Qun-Qun Jiang Mei-Fang Han Ke Ma Guang Chen Xiao-Yang Wan Semvua Bukheti Kilonzo Wen-Yu Wu Yong-Li Wang Jie You Qin Ning 2018World Journal of Gastroenterology2018,24,21:25
9Effect of low-nitrogen stress on photosynthesis and chlorophyll fluorescence characteristics of maize cultivars with different low-nitrogen tolerances显示文摘Nitrogen(N)is a critical element for plant growth and productivity that influences photosynthesis and chlorophyll fluorescence.We investigated the effect of low-N stress on leaf photosynthesis and chlorophyll fluorescence characteristics of maize cultivars with difference in tolerance to low N levels.The low-N tolerant cultivar ZH311 and low-N sensitive cultivar XY508 were used as the test materials.A field experiment(with three N levels:N0,0 kg ha–1;N1,150 kg ha–1;N2,300 kg ha–1)in Jiyanyang,Sichuan Province,China,and a hydroponic experiment(with two N levels:CK,4 mmol L–1;LN,0.04 mmol L–1)in Chengdu,Sichuan Province,China were conducted.Low-N stress significantly decreased chlorophyll content and rapid light response curves of the maximum fluorescence under light(Fm′),fluorescence instable state(Fs),non-photochemical quenching(qN),the maximum efficiency of PSII photochemistry under dark-adaption(Fv/Fm),potential activity of PSII(Fv/Fo),and actual photochemical efficiency of PSII(ΦPSII)of leaves.Further,it increased the chlorophyll(Chl)a/Chl b values and so on.The light compensation point of ZH311 decreased,while that of XY508 increased.The degree of variation of these indices in low-N tolerant cultivars was lower than that in low-N sensitive cultivars,especially at the seedling stage.Maize could increase Chl a/Chl b,apparent quantum yield and light saturation point to adapt to N stress.Compared to low-N sensitive cultivars,low-N tolerant cultivars maintained a higher net photosynthetic rate and electron transport rate to maintain stronger PSII activity,which further promoted the ability to harvest and transfer light.This might be a photosynthetic mechanism by which low-N tolerant cultivar adapt to low-N stress.WU Ya-wei LI Qiang JIN Rong CHEN Wei LIU Xiao-lin KONG Fan-lei KE Yong-pei SHI Haichun YUAN Ji-chao 2019Journal of Integrative Agriculture2019,18,6:25

11Systematic review and meta-analysis of laparoscopy-assisted and open total gastrectomy for gastric cancer显示文摘AIM:To evaluate the safety and efficacy of laparoscopy-assisted total gastrectomy(LATG)and open total gastrectomy(OTG)for gastric cancer.METHODS:A comprehensive search of PubMed,Cochrane Library,Web of Science and BIOSIS Previews was performed to identify studies that compared LATG and OTG.The following factors were checked:operating time,blood loss,harvested lymph nodes,flatus time,hospital stay,mortality and morbidity.Data synthesis and statistical analysis were carried out using RevMan 5.1 software.RESULTS:Nine studies with 1221 participants were included(436 LATG and 785 OTG).Compared to OTG,LATG involved a longer operating time[weighted mean difference(WMD)=57.68 min,95%CI:30.48-84.88;P<0.001];less blood loss[standard mean difference(SMD)=-1.71;95%CI:-2.48--0.49;P<0.001];earlier time to flatus(WMD=-0.76 d;95%CI:-1.22--0.30;P<0.001);shorter hospital stay(WMD=-2.67d;95%CI:-3.96--1.38,P<0.001);and a decrease in medical complications(RR=0.41,95%CI:0.19-0.90,P=0.03).The number of harvested lymph nodes,mortality,surgical complications,cancer recurrence rate and long-term survival rate of patients undergoing LATG were similar to those in patients undergoing OTG.CONCLUSION:Despite a longer operation,LATG can be performed safely in experienced surgical centers with a shorter hospital stay and fewer complications than open surgery.Ke Chen Xiao-Wu Xu Ren-Chao Zhang Yu Pan Di Wu Yi-Ping Mou 2013World Journal of Gastroenterology2013,19,32:23
12Mechanism of electroacupuncture on inflammatory pain: neural-immune-endocrine interactions显示文摘Nociceptive signals are transmitted by peripheral afferents to the central nervous system under pain condition, a process that involves various neurotransmitters and pathways. Electroacupuncture (EA) has been widely used as a pain management technique in clinical practice. Emerging studies have shown that EA can inhibit the induction and transmission of pain signals and, consequently, mediate anti-nociceptive and anti-inflammatory effects by rebalancing the neural-immune-endocrine interactions. This review summarizes the neural-immune- endocrine circuit including peripheral afferent and central efferent, contributing to EA-induced neuroimmune and neuroendocrine modulation in inflammatory pain models. The peripheral afferent circuit includes crosstalk among immune cells, inflammatory cytokines, peripheral nociceptors. In central efferent primarily involves the neuroinflammatory interactions between spinal nociceptive neurons and glial cells. Furthermore, the hypothalamic- pituitary-adrenal axis, sympathetic and vagal nervous may serve as an essential pathway involved in the mechanism of acupuncture-mediated analgesia within the interactions of the central, immune and endocrine systems. Overall, this review focuses on the interactions of neural-immune-endocrine in inflammatory pain, which may be underlying the mechanism of EA-induced anti-inflammatory and antinociceptive effect.Li Yuan Yang Mingxiao Wu Fan Cheng Ke Chen Haiyong Shen Xueyong Lao Lixing 2019Journal of Traditional Chinese Medicine2019,39,5:20
13Deformation and failure characteristics of anchorage structure of surrounding rock in deep roadway显示文摘This paper investigated the stress evolution,displacement field,local deformation and its overall distribution,and failure characteristics of the anchorage structure of surrounding rock with different rockbolt spacing through the model experiments.The influences of the pre-tightening force and spacing of rockbolt on the support strength of the anchorage structure of surrounding rock were analyzed by the simulation using FLAC3D numerical software.The support scheme of the excavated roadway was then designed,and the effectiveness of this support scheme was further verified by the displacement measurement of the roadway.The results showed that the maximum displacement between the roof and floor of the west wing track roadway in Kouzidong coal mine,China is about 42 mm,and the maximum displacement between its both sides is about 72 mm,indicating that the support scheme proposed in this study can ensure the stability and safety of the excavated roadway.Hongwen Jing Jiangyu Wu Qian Yin Ke Wang 2020International Journal of Mining Science and Technology2020,30,5:19
14Adenovirus-mediated gene delivery:Potential applications for gene and cell-based therapies in the new era of personalized medicine显示文摘With rapid advances in understanding molecular pathogenesis of human diseases in the era of genome sciences and systems biology,it is anticipated that increasing numbers of therapeutic genes or targets will become available for targeted therapies.Despite numerous setbacks,efficacious gene and/or cell-based therapies still hold the great promise to revolutionize the clinical management of human diseases.It is wildly recognized that poor gene delivery is the limiting factor for most in vivo gene therapies.There has been a long-lasting interest in using viral vectors,especially adenoviral vectors,to deliver therapeutic genes for the past two decades.Among all currently available viral vectors,adenovirus is the most efficient gene delivery system in a broad range of cell and tissue types.The applications of adenoviral vectors in gene delivery have greatly increased in number and efficiency since their initial development.In fact,among over 2000 gene therapy clinical trials approved worldwide since 1989,a significant portion of the trials have utilized adenoviral vectors.This review aims to provide a comprehensive overview on the characteristics of adenoviral vectors,including adenoviral biology,approaches to engineering adenoviral vectors,and their applications in clinical and preclinical studies with an emphasis in the areas of cancer treatment,vaccination and regenerative medicine.Current challenges and future directions regarding the use of adenoviral vectors are also discussed.It is expected that the continued improvements in adenoviral vectors should provide great opportunities for cell and gene therapies to live up to its enormous potential in personalized medicine.Cody S.Lee Elliot S.Bishop Ruyi Zhang Xinyi Yu Evan M.Farina Shujuan Yan Chen Zhao Zongyue Zeng Yi Shu Xingye Wu Jiayan Lei Yasha Li Wenwen Zhang Chao Yang Ke Wu Ying Wu Sherwin Ho Aravind Athiviraham Michael J.Lee Jennifer Moriatis Wolf Russell R.Reid Tong-Chuan He 2017Genes & Diseases2017,4,2:19
15Totally laparoscopic gastrectomy for gastric cancer: A systematic review and meta-analysis of outcomes compared with open surgery显示文摘AIM:To systematically review the surgical outcomes of totally laparoscopic gastrectomy(TLG)vs open gastrectomy(OG)for gastric cancer.METHODS:A systematic search of PubMed,Embase,Cochrane Library,and Web of Science was conducted.All original studies comparing TLG with OG were included for critical appraisal.Data synthesis and statistical analysis were carried out using RevMan 5.1 software.RESULTS:One RCT and 13 observational studies involving 1532 patients were included(721 TLG and811 OG).TLG was associated with longer operation time[weighted mean difference(WMD)=58.04min,95%CI:37.77-78.32,P<0.001],less blood loss[WMD=-167.57 min,95%CI:-208.79-(-126.34),P<0.001],shorter hospital stay[WMD=-3.75 d,95%CI:-4.88-(-2.63),P<0.001]and fewer postoperative complications(RR=0.71,95%CI:0.58-0.86,P<0.001).The number of harvested lymph nodes,surgical margin,mortality and cancer recurrence rate were similar between the two groups.CONCLUSION:TLG may be a technically safe,feasible and favorable approach in terms of better cosmesis,less blood loss and faster recovery compared with OG.Ke Chen Yu Pan Jia-Qin Cai Xiao-Wu Xu Di Wu Yi-Ping Mou 2014World Journal of Gastroenterology2014,20,42:19
16Regulation of OsSPX1 and OsSPX3 on Expression of OsSPX Domain Genes and Pi-starvation Signaling in Rice显示文摘The rice(Oryza sativa L.) genome contains at least six genes exclusively with an SPX(SYG1/PHO81/XPR1) domain at the N-terminal,designated as OsSPX1-6.Here we report the diverse expression patterns of the OsSPX genes in different tissues and their responses to Pi-starvation.Among them,five genes,OsSPX1,2,3,5 and 6 are responsive to Pi-starvation in shoots and/or in roots.The subcellular localization analysis indicates that OsSPX1 and OsSPX2 is exclusively located in nucleus,OsSPX3 in the cytoplasm,and OsSPX4 is a membrane localization protein.OsSPX1 regulates OsSPX2,3 and 5 at the transcription level and is positively involved in the responses of the genes to Pi-starvation.Overexpression of OsSPX3 downregulates OsSPX5 in shoots under Pi-sufficiency.OsSPX3 negatively regulates the PSI(Pi-starvation induced) gene,OsIPS1 and is involved in the responses of miR399 and OsPHO2 to Pi-starvation.Our results suggest that OsSPX1 may be a regulator involved in the transcriptions of OsSPX2,3 and 5.OsSPX3 plays a role in OsIPS1/miR399 mediated long distance regulation on OsPHO2.Our results also indicate that OsSPX3 is involved in plant tolerance to Pi-starvation stress.Zhiye Wang Han Hu Hongjie Huang Ke Duan Zhong changWu Ping Wu 2009Journal of Integrative Plant Biology2009,51,7:18

19Observation of atmospheric nitrous acid with DOAS in Beijing, China显示文摘Measurements of nitrous acid(HONO) and nitrogen dioxide(NO2) in Beijing City have been performed by means of a developed differential optical absorption spectroscopy(DOAS) system based on photodiode array(PDA), during the autumn of 2004. HONO and NO2 were simultaneously identified by their characteristic absorption bands in the spectral region between 337 nm and 372 nm with high sensibility and time resolution. The concentrations of HONO exhibit obviously diurnal variation with a nocturnal maximum and a daytime minimum. The highest HONO value up to 11.8 ?滋g/m3 was observed during the night of 2/3 September. Possible sources of the observed HONO were discussed. Good correlation to NO2 indicates that NO2 is a main source component. The measurement also shows direct emission of HONO is an important source in strongly polluted urban area.QIN Min XIE Pin-hua LIU Wen-qing LI Ang DOU Ke FANG Wu LIU Jian-guo ZHANG Wei-jun 2006Journal of Environmental Sciences2006,18,1:15
