| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018,63,23: | 54 |
| 2 | Huangqi Guizhi Wuwu Decoction for treating diabetic peripheral neuropathy:a meta-analysis of 16 randomized controlled trials显示文摘OBJECTIVE:This meta-analysis was performed to systematically assess the efficacy and safety of the Chinese herbal medicine Huangqi Guizhi Wuwu Decoction(HGWWD) for treating diabetic peripheral neuropathy.DATA SOURCES:Six electronic databases,including the Cochrane Library,MEDLINE database,Chinese Biomedical Database,Chinese National Knowledge Infrastructure Database,Chinese Science and Technique Journals Database,and the Wanfang Database,were search ed on the internet for randomized controlled trials published up until 1 December 2015.The search terms included 'Chinese herbal medicine','diabetic peripheral neuropathy' and 'randomized controlled trials' in Chinese and in English.DATA SELECTION:We included randomized controlled trials using HGWWD/modified HGWWD for the treatment group,without restriction for the control group.We assessed literature quality in accordance with the Cochrane Review Handbook.A random or a fixed effects model was used to analyze outcomes using Rev Man 5.2 software.OUTCOME MEASURES:The primary outcomes were changes in symptoms and nerve conduction velocities.The secondary outcomeswere fasting blood glucose and hemorheological indexes.RESULTS:Sixteen randomized controlled trials,with a total of 1,173 patients,were included.Meta-analysis revealed that the efficacy of HGWWD for diabetic peripheral neuropathy was significantly superior compared with the control treatment(i.e.,control group)(risk ratio = 0.36,95% confidence interval(CI):0.29–0.46,Z =8.33,P < 0.00001) Compared with the control group,there was an increase in median motor nerve conduction velocity(mean difference(MD) = 3.46,95%CI:1.88–5.04,Z = 4.30,P < 0.01) and median sensory nerve conduction velocity(MD = 3.30,95%CI:2.04–4.56,Z = 5.14,P < 0.01).There was also an increase in peroneal motor nerve conduction velocity(MD = 3.22,95%CI:2.45–3.98,Z = 8.21,P < 0.01) and peroneal sensory nerve conduction velocity(MD = 3.05,95%CI:2.01–4.09,Z = 5.75,P < 0.01) in the treatment groups.No significant difference in fasting blood glucose was found between the treatment groups and the control groups(MD =-0.12,95%CI:-0.42–0.19,Z = 0.76,P = 0.45).Plasma viscosity was significantly decreased after treatment(MD =-0.11,95%CI:-0.21 to-0.02,Z = 2.30,P = 0.02).No significant difference in fibrinogen was detectable(MD =-0.53,95%CI:-1.28–0.22,Z = 1.38,P = 0.17).Four trials reported that treatment groups experienced no adverse reactions.Adverse events were not mentioned in the other 12 trials.No trial reported the incidence of complications,quality of life outcomes,or health economics.CONCLUSION:HGWWD treatment improves diabetic neurologic symptoms and ameliorates nerve conduction velocities.Our study suggests that HGWWD may have significant therapeutic efficacy for the treatment of diabetic peripheral neuropathy.However,the methodological quality of the randomized controlled trials was generally low.Larger and better-designed randomized controlled trials are required to more reliably assess the clinical effectiveness of HGWWD. | Bing Pang Tian-yu Zhao Lin-hua Zhao Fang Wan Ru Ye Qiang Zhou Feng Tian Xiao-lin Tong | 2016 | Neural Regeneration Research2016,11,8: | 32 |
| 3 | Special Section:SARS-CoV-2 Preliminary evidence from a multicenter prospective observational study of the safety and efficacy of chloroquine for the treatment of COVID-19显示文摘Effective therapies are urgently needed for the SARS-CoV-2 pandemic.Chloroquine has been proved to have antiviral effect against coronavirus in vitro.In this study,we aimed to assess the efficacy and safety of chloroquine with different doses in COVID-19.In this multicenter prospective observational study,we enrolled patients older than 18 years old with confirmed SARS-CoV-2 infection excluding critical cases from 12 hospitals in Guangdong and Hubei Provinces.Eligible patients received chloroquinephosphate s00 mg,orally,once(half dose)or twice(full dose)daily.Patients treated with non-chloroquine therapy were included as historical controls.The primary endpoint is the time to undetectable viral RNA.Secondary outcomes include the proportion of patients with undetectable viral RNA by day 10 and 14,hospitalization time,duration of fever,and adverse events.A total of 197 patients completed chloroquine treatment,and 176patients were included as historical controls.The median time to achieve an undetectable viral RNA was shorter in chloroquine than in non-chloroquine(absolute difference in medians-6.0 days;95%CI-6.0 to—4.0).The duration of fever is shorter in chloroquine(geometric mean ratio 0.6;95%CIO.5 to 0.8).No serious adverse events were observed in the chloroquine group.Patients treated with half dose experienced lower rate of adverse events than with full dose.Although randomized trials are needed for further evaluation,this study provides evidence for safety and efficacy of chloroquine in COVID-19 and suggests that chloroquine can be a cost-effective therapy for combating the COVID-19 pandemic. | Mingxing Huang Man Li Fei Xiao Pengfei Pang Jiabi Liang Tiantian Tang Shaoxuan Liu Binghui Chen Jingxian Shu Yingying You Yang Li Meiwen Tang Jianhui Zhou Guanmin Jiang Jingfen Xiang Wenxin Hong Songmei He Zhaoqin Wang Jianhua Feng Changqing Lin Yinong Ye Zhilong Wu Yaocai Li Bei Zhong Ruilin Sun Zhongsi Hong Jing Liu Huili Chen Xiaohua Wang Zhonghe Li Duanqing Pei Lin Tian Jinyu Xia Shanping Jiang Nanshan Zhong Hong Shan | 2020 | National Science Review2020,7,9: | 20 |
| 4 | Liproxstatin-1 is an effective inhibitor of oligodendrocyte ferroptosis induced by inhibition of glutathione peroxidase 4显示文摘Our previous studies showed that ferroptosis plays an important role in the acute and subacute stages of spinal cord injury.High intracellular iron levels and low glutathione levels make oligodendrocytes vulnerable to cell death after central nervous system trauma.In this study,we established an oligodendrocyte(OLN-93 cell line)model of ferroptosis induced by RSL-3,an inhibitor of glutathione peroxidase 4(GPX4).RSL-3 significantly increased intracellular concentrations of reactive oxygen species and malondialdehyde.RSL-3 also inhibited the main antiferroptosis pathway,i.e.,SLC7A11/glutathione/glutathione peroxidase 4(xCT/GSH/GPX4),and downregulated acyl-coenzyme A synthetase long chain family member 4.Furthermore,we evaluated the ability of several compounds to rescue oligodendrocytes from ferroptosis.Liproxstatin-1 was more potent than edaravone or deferoxamine.Liproxstatin-1 not only inhibited mitochondrial lipid peroxidation,but also restored the expression of GSH,GPX4 and ferroptosis suppressor protein 1.These findings suggest that GPX4 inhibition induces ferroptosis in oligodendrocytes,and that liproxstatin-1 is a potent inhibitor of ferroptosis.Therefore,liproxstatin-1 may be a promising drug for the treatment of central nervous system diseases. | Bao-You Fan Yi-Lin Pang Wen-Xiang Li Chen-Xi Zhao Yan Zhang Xu Wang Guang-Zhi Ning Xiao-Hong Kong Chang Liu Xue Yao Shi-Qing Feng | 2021 | Neural Regeneration Research2021,16,3: | 19 |
| 5 | Grape Seed Proanthocyanidin Extract Alleviates Arsenic-induced Oxidative Reproductive Toxicity in Male Mice显示文摘Objective To determine the ability of grape seed proanthocyanidin extract(GSPE) in alleviating arsenic-induced reproductive toxicity. Methods Sixty male Kunming mice received the following treatments by gavage: normal saline solution(control); arsenic trioxide(ATO; 4 mg/kg); GSPE(400 mg/kg); ATO+GSPE(100 mg/kg); ATO+GSPE(200 mg/kg) and ATO+GSPE(400 mg/kg). Thereafter, the mice were sacrificed and weighed, and the testis was examined for pathological changes. Nuclear factor(erythroid-derived 2)-like 2(Nrf2), heme oxygenase 1(HO1), glutathione S-transferase(GST), NAD(P)H dehydrogenase, and quinone 1(NQO1) expression in the testis was detected by real-time PCR. Superoxide dismutase(SOD), glutathione(GSH), total antioxidative capability(T-AOC), malondialdehyde(MDA), 8-hydroxydeoxyguanosine(8-OHd G), and reproductive indexes were analyzed. Results ATO-treated mice showed a significantly decreased sperm count and testis somatic index and activity levels of SOD, GSH, and T-AOC than control group. Compared to the ATO-treated group, ATO +GSPE group showed recovery of the measured parameters. Mice treated with ATO+high-dose GSPE showed the highest level of m RNA expression of Nrf2, HO, NQO1, and GST. Conclusion GSPE alleviates oxidative stress damage in mouse testis by activating Nrf2 signaling, thus counteracting arsenic-induced reproductive toxicity. | LI Shu Gang DING Yu Song NIU Qiang XU Shang Zhi PANG Li Juan MA Ru Lin JING Ming Xia FENG Gang Ling LIU Jia Ming GUO Shu Xia | 2015 | Biomedical and Environmental Sciences2015,28,4: | 14 |
| 6 | Trends and challenges of emergency and acute care in Chinese mainland:2005–2017显示文摘BACKGROUND:Emergency medical service system(EMSS)is essential in providing acute care services for health conditions.However,trends of emergency and acute care in China haven’t been studied systematically.METHODS:Relevant literature was carefully reviewed,including original and review articles,letters,government reports,yearbooks,both in Chinese and in English.Data on the number of emergency visits,physicians and beds in emergency departments(EDs),and the workforce of prehospital emergency care were summarized and analyzed from China Health and Family Planning Statistical Yearbooks(2006–2018).RESULTS:Over the past decade,the number of ED visits tripled from 51.9 million to 166.5 million;and utilization of pre-hospital emergency care increased from 3.2 million to 6.8 million.In response to rapid increases in demand,the number of licensed emergency physicians raised from 20,058 to 59,409;the beds’number increased from 10,783 to 42,367.For pre-hospital emergency care,the volume of health workforce increased from 3,687 to 8,671,with a 109%increase in the number of physicians from 1,774 to 3,712.However,overcrowding,the long length of stay in EDs,poor work environment,and work exhaustion were still the critical challenges faced by China’s EMSS.CONCLUSIONS:The number of emergency visits has grown with continual capability enhancement during the past decade.However,overcrowding,the long length of stay in EDs,poor work environment,and work exhaustion still need to be solved by China’s EMSS.These fi ndings and comparison with the USA could offer experiences and lessons to EMSS development worldwide,especially for developing countries. | Chang Pan Jiao-jiao Pang Kai Cheng Feng Xu Yu-guo Chen | 2021 | World Journal of Emergency Medicine2021,12,1: | 14 |
| 7 | Au-decorated porous structure graphene with enhanced sensing performance for low-concentration NO2 detection显示文摘A recent progress in new emerging two-dimensional(2 D)materials has provided promising opportunity for gas sensing in ultra-low detectable concentration.In this work,we have demonstrated a flexible NO2 gas sensor with porous structure graphene on polyethylene terephthalate substrates operating at room temperature.The gas sensor exhibited good performance with response of 1.2%and a fast response time within 30 s after exposure to50×10^-9 NO2 gas.As porous structure of graphene increased the surface area,the sensor showed high sensitivity of ppb level for NO2 detection.Au nanoparticles were decorated on the surface of the porous structure graphene skeleton,resulting in an incensement of response compared with pristine graphene.Au nanoparticles-decorated graphene exhibits not only better sensitivity(1.5-1.6 times larger than pristine graphene)for NO2 gas detection,but also fast response.The sensor was found to be robust and sensitive under the cycling bending test,which could also be ascribed to the merits of graphene.This porous structure graphene-based gas sensor is expected to enable a simple and inexpensive flexible gas sensing platform. | Yan-Yan Fan Hai-Ling Tu Yu Pang Feng Wei Hong-Bin Zhao Yi Yang Tian-Ling Ren | 2020 | Rare Metals2020,39,6: | 13 |
| 8 | Trends in mortality of emergency departments patients in China显示文摘BACKGROUND: Emergency medical service system (EMSS) in China is becoming more important. However, studies on mortality of emergency departments (EDs) patients in tertiary hospitals and on the trends in mortality of ED patients all over China are stagnant. The objective of this study was to quantify and describe the trends in mortality of ED patients in China. METHODS: Nine tertiary teaching hospitals were selected from tertiary teaching hospitals in different regions. The annual numbers of ED visits and deaths of these hospitals in 2004, 2009 and 2014 were recorded and analyzed. Chi-square test was used to compare the mortality of the EDs’ visits. Moreover, data on the mortality of ED patients in China from 2005 to 2015 were summarized and analyzed from the China Health and Family Planning Statistical Yearbooks (2006–2016). RESULTS: From 2004 to 2014, the overall annual mortalities in EDs increased among the tertiary hospitals (P<0.001). However, the overall annual mortality in EDs all over China decreased from 0.12% in 2005 to 0.08% in 2015. And the mortalities of EDs patients in the eastern, central and western regions of China all decreased. In addition, the average mortality of EDs patients in northern China was obviously higher than that in southern China (P<0.05). CONCLUSION: The ED mortality was increased in tertiary hospitals while decreased all over China during the past decade, which may be partly caused by some critical challenges faced by China’s EMSS, such as overcrowding and long length of stay in EDs of tertiary hospitals. | Chang Pan Xiao-ran Huang Jiao-jiao Pang Kai Cheng Feng Xu Yu-guo Chen | 2019 | World Journal of Emergency Medicine2019,10,3: | 11 |
| 9 | Tight sandstone gas accumulation mechanism and development models显示文摘Tight sandstone gas serves as an important unconventional hydrocarbon resource, and outstanding results have been obtained through its discovery both in China and abroad given its great resource potential.However, heated debates and gaps still remain regarding classification standards of tight sandstone gas, and critical controlling factors, accumulation mechanisms, and development modes of tight sandstone reservoirs are not determined. Tight sandstone gas reservoirs in China are generally characterized by tight strata, widespread distribution areas, coal strata supplying gas, complex gas–water relations, and abnormally low gas reservoir pressure. Water and gas reversal patterns have been detected via glass tube and quartz sand modeling, and the presence of critical geological conditions without buoyancy-driven mechanisms can thus be assumed. According to the timing of gas charging and reservoir tightening phases, the following three tight sandstone gas reservoir types have beenidentified:(a) ‘‘accumulation–densification''(AD), or the conventional tight type,(b) ‘‘densification–accumulation''(DA), or the deep tight type, and(c) the composite tight type. For the AD type, gas charging occurs prior to reservoir densification, accumulating in higher positions under buoyancy-controlled mechanisms with critical controlling factors such as source kitchens(S), regional overlaying cap rocks(C), gas reservoirs,(D) and low fluid potential areas(P). For the DA type, reservoir densification prior to the gas charging period(GCP) leads to accumulation in depressions and slopes largely due to hydrocarbon expansive forces without buoyancy, and critical controlling factors are effective source rocks(S), widely distributed reservoirs(D), stable tectonic settings(W) and universal densification of reservoirs(L). The composite type includes features of the AD type and DA type, and before and after reservoir densification period(RDP), gas charging and accumulation is controlled by early buoyancy and later molecular expansive force respectively. It is widely distributed in anticlinal zones, deep sag areas and slopes, and is controlled by source kitchens(S), reservoirs(D), cap rocks(C), stable tectonic settings(W), low fluid potential areas(P), and universal reservoir densification(L). Tight gas resources with great resource potential are widely distributed worldwide, and tight gas in China that presents advantageous reservoir-forming conditions is primarily found in the Ordos, Sichuan, Tarim, Junggar, and TurpanHami basins of central-western China. Tight gas has served as the primary impetus for global unconventional natural gas exploration and production under existing technical conditions. | Zhen-Xue Jiang Zhuo Li Feng Li Xiong-Qi Pang Wei Yang Luo-Fu Liu Fu-Jie Jiang | 2015 | Petroleum Science2015,12,4: | 10 |
| 10 | Association Between Serum Uric Acid and Prevalence of Type 2 Diabetes Diagnosed using HbA1c Criteria Among Chinese Adults in Qingdao,China显示文摘Objective To determine whether elevated serum uric acid(UA)levels are associated with type 2 diabetes diagnosed using Hb A1 c levels among Chinese adults.Methods We conducted two population-based cross-sectional studies in Qingdao in China in 2006 and 2009.A total of 6894(39.4% men)subjects aged 35-74 years were included in the data analysis.Newly diagnosed diabetes was defined as Hb A1 c level of ≥6.5%,and prediabetes was classified as Hb A1 c level between 5.7% and 6.4% according to the International Diabetes Federation criteria.Multivariate logistic regression was employed to assess the association between UA and prevalence of type 2 diabetes defined using Glycated hemoglobin A1c(Hb A1 c levels.Results Subjects with prediabetes had higher UA levels than those with normal glucose tolerance,newly diagnosed diabetes,and known diabetes,with corresponding values of 325.1(82.5)μmol/L,310.9(84.2)μmol/L,291.3(81.7)μmol/L,305.2(83.6)μmol/L,respectively(P<0.001 for all comparisons).Binary logistic regression analysis showed that UA was a possible predictor for the prevalence of type 2 diabetes diagnosed using Hb A1 c levels,and the second quartile of UA levels had a higher odds ratio(OR:4.088;95% CI:2.900-5.765)for Hb A1 c than the other quartiles after adjusting for age,body mass index,sex,marital status,education,income,alcohol consumption,smoking,and cardiometabolic parameters.Conclusion Serum UA is significantly associated with type 2 diabetes diagnosed using Hb A1 c levels,independent of other cardiometabolic parameters. | XUE Bai TAN Ji Bin NING Feng SUN Jian Ping ZHANG Ke Yi LIU Li WANG Shao Jie ZHANG Dong Feng QIAO Qing PANG Zeng Chang | 2015 | Biomedical and Environmental Sciences2015,28,12: | 9 |
| 11 | Neuroprotective effect of deferoxamine on erastin-induced ferroptosis in primary cortical neurons显示文摘The iron chelator deferoxamine has been shown to inhibit ferroptosis in spinal cord injury.However,it is unclear whether deferoxamine directly protects neurons from ferroptotic cell death.By comparing the survival rate and morphology of primary neurons and SH-SY5Y cells exposed to erastin,it was found that these cell types respond differentially to the duration and concentration of erastin treatment.Therefore,we studied the mechanisms of ferroptosis using primary cortical neurons from E16 mouse embryos.After treatment with 50μM erastin for 48 hours,reactive oxygen species levels increased,and the expression of the cystine/glutamate antiporter system light chain and glutathione peroxidase 4 decreased.Pretreatment with deferoxamine for 12 hours inhibited these changes,reduced cell death,and ameliorated cellular morphology.Pretreatment with the apoptosis inhibitor Z-DEVD-FMK or the necroptosis inhibitor necrostain-1 for 12 hours did not protect against erastin-induced ferroptosis.Only deferoxamine protected the primary cortical neurons from ferroptosis induced by erastin,confirming the specificity of the in vitro ferroptosis model.This study was approved by the Animal Ethics Committee at the Institute of Radiation Medicine of the Chinese Academy of Medical Sciences,China(approval No.DWLL-20180913)on September 13,2018. | Yan Zhang Bao-You Fan Yi-Lin Pang Wen-Yuan Shen Xu Wang Chen-Xi Zhao Wen-Xiang Li Chang Liu Xiao-Hong Kong Guang-Zhi Ning Shi-Qing Feng Xue Yao | 2020 | Neural Regeneration Research2020,15,8: | 9 |
| 12 | First proof-of-principle experiment with the post-accelerated isotope separator on-line beam at BRIF:measurement of the angular distribution of ^(23)Na+^(40)Ca elastic scattering显示文摘The reaction dynamics of exotic nuclei near the drip line is one of the main research topics of current interest.Elastic scattering is a useful probe for investigating the size and surface diffuseness of exotic nuclei.The development of rare isotope accelerators offers opportunities for such studies.To date,many relevant measurements have been performed at accelerators using the projectile fragmentation technique,while the measurements at accelerators using isotope separator on-line(ISOL)systems are still quite scarce.In this work,we present the first proof-of-principle experiment with a post-accelerated ISOL beam at the Beijing Radioactive Ion Beam Facility(BRIF)by measuring the angular distribution of elastic scattering for the stable nucleus^(23)Na from the doubly magic nucleus^(40)Ca at energies above the Coulomb barrier.The angular distribution measured by a silicon strip detector array in a scattering chamber using the ISOL beam at BRIF is in good agreement with that measured by the high-precision Q3 D magnetic spectrograph using the nonISOL beam at nearly the same energy.This work provides useful background for making BRIF a powerful tool for the investigation of the reaction dynamics of exotic nuclei. | Wei Nan Bing Guo Cheng-Jian Lin Lei Yang Dong-Xi Wang Yang-Ping Shen Bing Tang Bao-Qun Cui Tao Ge Yin-Long Lyu Hui-Ming Jia Yun-Ju Li Chen Chen Li-Hua Chen Qi-Wen Fan Xin-Yue Li Gang Lian Jian-Cheng Liu Tian-Peng Luo Nan-Ru Ma Rui-Gang Ma Xie Ma Ying-Jun Ma Wei-Ke Nan Dan-Yang Pang You-Bao Wang Pei-Wei Wen Feng Yang Yong-Jin Yao Sheng Zeng Hao Zhang Fu-Peng Zhong Shan-Hao Zhong Zhi-Hong Li Tian-Jue Zhang Wei-Ping Liu BRIF Collaboration | 2021 | Nuclear Science and Techniques2021,32,5: | 9 |
| 13 | Analysis of immunoglobulin, complements and CRP levels in serum of captive northern pig-tailed macaques (Macaca leonina)显示文摘The northern pig-tailed macaque(NPM,Macaca leonina) has become a widely used animal model in biomedical research. In this study, we measured serum immunoglobulin IgG, IgM, IgA, complement C3, C4 and CRP levels in 3-11 year old captive northern pig-tailed macaques using HITACHI 7600-20 automated chemistry analyzer in order to determine the influences of age and gender on these items. The results showed that serum IgA, IgM, C3 and C4 levels were not correlated with age(P>0.05), while serum IgG levels increased progressively with age(r=0.202;P=0.045). Serum IgG, IgA, IgM and C3 levels were higher in females than in males(P<0.05). Moreover, serum C3 concentration was both positively and strongly correlated with that of C4(r=0.700; P<0.0001). This study provides basic serum immunoglobulin and complement data of captive northern pig-tailed macaques, which may prove useful for future breeding efforts and biomedical research. | Xiao-Liang ZHANG Wei PANG De-Yao DENG Long-Bao LV Yue FENG Yong-Tang ZHENG | 2014 | Zoological Research2014,35,3: | 8 |
| 14 | Soil temperature and moisture sensitivities of soil CO_2 efflux before and after tillage in a wheat field of Loess Plateau,China显示文摘As a conventional farming practice,tillage has lasted for thousands of years in Loess Plateau,China.Although recent studies show that tillage is a prominent culprit to soil carbon loss in croplands,few studies have investigated the influences of tillage on the responses of soil CO2 efflux(SCE) to soil temperature and moisture.Using a multi-channel automated CO2 efflux chamber system,we measured SCE in situ continuously before and after the conventional tillage in a rain fed wheat field of Loess Plateau,China.The changes in soil temperature and moisture sensitivities of SCE,denoted by the Q10 value and linear regression slope respectively,were compared in the same range of soil temperature and moisture before and after the tillage.The results showed that,after the tillage,SCE increased by 1.2-2.2 times;the soil temperature sensitivity increased by 36.1%-37.5%;and the soil moisture sensitivity increased by 140%-166%.Thus,the tillage-induced increase in SCE might partially be attributed to the increases in temperature and moisture sensitivity of SCE. | Hongxing Zhang Xiaoke Wang Zongwei Feng Junzhu Pang Fei Lu Zhiyun Ouyang Hua Zheng Wenzhao Liu Dafeng Hui | 2011 | Journal of Environmental Sciences2011,23,1: | 7 |
| 15 | Applications of Three DNA Barcodes in Assorting Intertidal Red Macroalgal Flora in Qingdao, China显示文摘This study is part of the endeavor to construct a comprehensive DNA barcoding database for common seaweeds in China. Identifications of red seaweeds, which have simple morphology and anatomy, are sometimes difficult solely depending on morphological characteristics. In recent years, DNA barcode technique has become a more and more effective tool to help solve some of the taxonomic difficulties. Some DNA markers such as COI (cytochrome oxidase subunitⅠ) are proposed as standardized DNA barcodes for all seaweed species. In this study, COI, UPA (universal plastid amplicon, domain V of 23S rRNA), and ITS (nuclear internal transcribed spacer) were employed to analyze common species of intertidal red seaweeds in Qingdao (119.3 -121 E, 35.35 -37.09 N). The applicability of using one or a few combined barcodes to identify red seaweed species was tested. The results indicated that COI is a sensitive marker at species level. However, not all the tested species gave PCR amplification products due to lack of the universal primers. The second barcode UPA had effective universal primers but needed to be tested for the effectiveness of resolving closely related species. More than one ITS sequence types were found in some species in this investigation, which might lead to confusion in further analysis. Therefore ITS sequence is not recommended as a universal barcode for seaweeds identification. | ZHAO Xiaobo PANG Shaojun SHAN Tifeng LIU Feng | 2013 | Journal of Ocean University of China2013,12,1: | 7 |

| 17 | The R2R3-MYB transcription factor GhMYB1a regulates flavonol and anthocyanin accumulation in Gerbera hybrida显示文摘Anthocyanins and flavonols have vital roles in flower coloration,plant development,and defense.Because anthocyanins and flavonols share the same subcellular localization and common biosynthetic substrates,these pathways may compete for substrates.However,the mechanism regulating this potential competition remains unclear.Here,we identified GhMYB1a,an R2R3-MYB transcription factor involved in the regulation of anthocyanin and flavonol accumulation in gerbera(Gerbera hybrida).GhMYB1a shares high sequence similarity with that of other characterized regulators of flavonol biosynthesis.In addition,GhMYB1a is also phylogenetically grouped with these proteins.The overexpression of GhMYB1a in gerbera and tobacco(Nicotiana tabacum)resulted in decreased anthocyanin accumulation and increased accumulation of flavonols by upregulating the structural genes involved in flavonol biosynthesis.We further found that GhMYB1a functions as a homodimer instead of interacting with basic helix-loop-helix cofactors.These results suggest that GhMYB1a is involved in regulating the anthocyanin and flavonol metabolic pathways through precise regulation of gene expression.The functional characterization of GhMYB1a provides insight into the biosynthesis and regulation of flavonols and anthocyanins. | Chunmei Zhong Yi Tang Bin Pang Xukun Li Yuping Yang Jing Deng Chengyong Feng Lingfei Li Guiping Ren Yaqin Wang Jianzong Peng Shulan Sun Shan Liang Xiaojing Wang | 2020 | Horticulture Research2020,7,1: | 7 |

| 19 | Preparation of mulberry-like RuO_(2) electrode material for supercapacitors显示文摘As a newly emerging excellent energy storage device,supercapacitors have been widely studied due to their unique advantages.Electrode material is one of the key components that determine the performance of a supercapacitor.Among the various electrode materials of supercapacitors,RuO_(2) has attracted great attention in the scientific community due to its high theoretical energy storage capability and excellent stability.However,most RuO_(2) materials suffer the problem of low specific surface area,causing a much lower actual capacitance value compared to the theoretical performance of the material.In this work,a mulberry-like RuO_(2) electrode material with large specific surface area(159.4 m^(2)·g^(-1))was successfully synthesized by a facial hydrothermal method.The electrochemical characterization has shown that the RuO_(2) possesses a high specific capacitance of 400 F·g^(-1) at a current density of 0.2 A·g^(-1) and good capacitance retention rate of 84.7%after 6000 charge/discharge cycles under a current density of 10 A·g^(-1).The energy densities and power densities of the RuO_(2)-AC supercapacitor vary from25.0 to 11.7 Wh·kg^(-1) and 160 to 10,560 W·kg^(-1) at current density ranging from 0.2 to 10.0 A·g^(-1),respectively. | Feng Yu Le Pang Hong-Xia Wang | 2021 | Rare Metals2021,40,2: | 6 |

PCa responds poorly to most chemotherapeutic agents, and therefore it is imperative to develop novel therapeutic agents that have anti-cancer activities against PCa. | Juanjuan Feng Mingjin Rao Man Wang Lin Liang Zhi Chen Xiufeng Pang Weiqiang Lu Zhenliang Sun | 2019 | Science China(Life Sciences)2019,62,10: | 6 |
