| 1 | Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China显示文摘To control the spread of the 2019 novel coronavirus(COVID-19),China imposed nationwide restrictions on the movement of its population(lockdown)after the Chinese New Year of 2020,leading to large reductions in economic activities and associated emissions.Despite such large decreases in primary pollution,there were nonetheless several periods of heavy haze pollution in eastern China,raising questions about the well-established relationship between human activities and air quality.Here,using comprehensive measurements and modeling,we show that the haze during the COVID lockdown was driven by enhancements of secondary pollution.In particular,large decreases in NOx emissions from transportation increased ozone and nighttime NO_(3)radical formation,and these increases in atmospheric oxidizing capacity in turn facilitated the formation of secondary particulate matter.Our results,afforded by the tragic natural experiment of the COVID-19 pandemic,indicate that haze mitigation depends upon a coordinated and balanced strategy for controlling multiple pollutants. | Xin Huang Aijun Ding Jian Gao Bo Zheng Derong Zhou Ximeng Qi Rong Tang Jiaping Wang Chuanhua Ren Wei Nie Xuguang Chi Zheng Xu Liangduo Chen Yuanyuan Li Fei Che Nini Pang Haikun Wang Dan Tong Wei Qin Wei Cheng Weijing Liu Qingyan Fu Baoxian Liu Fahe Chai Steven JDavis Qiang Zhang Kebin He | 2021 | National Science Review2021,8,2: | 47 |

| 3 | New incompatible pair of TCM:Epimedii Folium combined with Psoraleae Fructus induces idiosyncratic hepatotoxicity under immunological stress conditions显示文摘Epimedii Folium(EF)combined with Psoraleae Fructus(PF)is a common modern preparation,but liver injury caused by Chinese patent medicine preparations containing EF and PF has been frequently reported in recent years.Zhuangguguanjiewan pills(ZGW),which contain EF and PF,could induce immune idiosyncratic liver injury according to clinical case reports and a nonhepatotoxic dose of lipopolysaccharide(LPS)model.This present study evaluated the liver injury induced by EF or PF alone or in combination and investigated the related mechanism by using the LPS model.Liver function indexes and pathological results showed that either EF or PF alone or in combination led to liver injury in normal rats;however,EF or PF alone could lead to liver injury in LPS-treated rats.Moreover,EF combined with PF could induce a greater degree of injury than that caused by EF or PF alone in LPS-treated rats.Furthermore,EF or PF alone or in combination enhanced the LPS-stimulated inflammatory cytokine production,implying that IL-1β,which is processed and released by activating the NLRP3 inflammasome,is a specific indicator of EF-induced immune idiosyncratic hepatotoxicity.Thus,EF may induce liver injury through enhancing the LPS-mediated proinflammatory cytokine production and activating the NLRP3 inflammasome.In addition,the metabolomics analysis results showed that PF affected more metabolites in glycerophospholipid and sphingolipid metabolic pathways compared with EF in LPS model,suggesting that PF increased the responsiveness of the liver to LPS or other inflammatory mediators via modulation of multiple metabolic pathways.Therefore,EF and PF combination indicates traditional Chinese medicine incompatibility,considering that it induces idiosyncratic hepatotoxicity under immunological stress conditions. | Yuan Gao Zhilei Wang Jinfa Tang Xiaoyi Liu Wei Shi Nan Qin Xiaoyan Wang Yu Pang Ruisheng Li Yaming Zhang Jiabo Wang Ming Niu Zhaofang Bai Xiaohe Xiao | 2020 | Frontiers of Medicine2020,14,1: | 32 |
| 4 | Ablation of gut microbiota alleviates obesity-induced hepatic steatosis and glucose intolerance by modulating bile acid metabolism in hamsters显示文摘Since metabolic process differs between humans and mice, studies were performed in hamsters, which are generally considered to be a more appropriate animal model for studies of obesityrelated metabolic disorders. The modulation of gut microbiota, bile acids and the farnesoid X receptor(FXR) axis is correlated with obesity-induced insulin resistance and hepatic steatosis in mice. However,the interactions among the gut microbiota, bile acids and FXR in metabolic disorders remained largely unexplored in hamsters. In the current study, hamsters fed a 60% high-fat diet(HFD) were administeredvehicle or an antibiotic cocktail by gavage twice a week for four weeks. Antibiotic treatment alleviated HFD-induced glucose intolerance, hepatic steatosis and inflammation accompanied with decreased hepatic lipogenesis and elevated thermogenesis in subcutaneous white adipose tissue(sWAT). In the livers of antibiotic-treated hamsters, cytochrome P450 family 7 subfamily B member 1(CYP7 B1) in the alternative bile acid synthesis pathway was upregulated, contributing to a more hydrophilic bile acid profile with increased tauro-β-muricholic acid(TβMCA). The intestinal FXR signaling was suppressed but remained unchanged in the liver. This study is of potential translational significance in determining the role of gut microbiota-mediated bile acid metabolism in modulating diet-induced glucose intolerance and hepatic steatosis in the hamster. | Lulu Sun Yuanyuan Pang Xuemei Wang Qing Wu Huiying Liu Bo Liu George Liu Min Ye Wei Kong Changtao Jiang | 2019 | Acta Pharmaceutica Sinica B2019,9,4: | 29 |
| 5 | Programmed death-1 expression is associated with the disease status in hepatitis B virus infection显示文摘AIM: To define the potential role of programmed death-1/programmed death-ligand (PD-1/PD-L) pathway in different hepatitis B virus (HBV) infection disease status; we examined the expression of PD-1 on antigen specific CD8+ T cells in peripheral blood of patients with chronic hepatitis B (CHB) and acute exacerbation of hepatitis B (AEHB) infection. METHODS: The PD-1 level on CD8+ T lymphocytes and the number of HBV specifi c CD8+ T lymphocytes in patients and healthy controls (HCs) were analyzed by staining with pentameric peptide-human leukocyte antigen2 (HLA2) complexes combined with flow cytometry. Real-time quantitative polymerase chain reaction (PCR) was used to measure the serum HBV-DNA levels. RESULTS: The level of PD-1 expression on total CD8+ T cells in CHB patients (13.86% ± 3.38%) was significantly higher than that in AEHB patients (6.80%± 2.19%, P < 0.01) and healthy individuals (4.63% ± 1.23%, P < 0.01). Compared to AEHB patients (0.81% ± 0.73%), lower frequency of HBV-specific CD8+ T cells was detected in chronic hepatitis B patients (0.37% ± 0.43%, P < 0.05). There was an inverse correlation between the strength of HBV-specific CD8+ T-cell response and the level of PD-1 expression. Besides, there was a significant positive correlation between HBV viral load and the percentage of PD-1 expression on CD8+ T cells in CHB and AEHB subjects (R = 0.541, P < 0.01). However, PD-1 expression was not associated with disease flare-ups as indicated by alanine aminotransferase (ALT) levels (R = 0.066, P > 0.05). CONCLUSION: Our results confirm previous reports that HBV specific CD8+ T-cell response in the peripheral blood is more intense in patients with AEHB than in chronic hepatitis B with persistent viral infection. Moreover, there is a negative correlation between the level of PD-1 and the intensity of virus specific CD8+T cell response. | Plan Ye Zhi-Hong Weng Shu-Ling Zhang Jian-Ao Zhang Lei Zhao Ji-Hua Dong Sheng-Hua Jie Ran Pang Rong-Hua Wei | 2008 | World Journal of Gastroenterology2008,14,28: | 25 |
| 6 | Infection with novel coronavirus(SARS-CoV-2)causes pneumonia in Rhesus macaques显示文摘The 2019 novel coronavirus(SARS-CoV-2)outbreak is a major challenge for public health.SARS-CoV-2 infection in human has a broad clinical spectrum ranging from mild to severe cases,with a mortality rate of^6.4%worldwide(based on World Health Organization daily situation report).However,the dynamics of viral infection,replication and shedding are poorly understood.Here,we show that Rhesus macaques are susceptible to the infection by SARS-CoV-2.After intratracheal inoculation,the first peak of viral RNA was observed in oropharyngeal swabs one day post infection(1 d.p.i.),mainly from the input of the inoculation,while the second peak occurred at 5 d.p.i.,which reflected on-site replication in the respiratory tract.Histopathological observation shows that SARS-CoV-2 infection can cause interstitial pneumonia in animals,characterized by hyperemia and edema,and infiltration of monocytes and lymphocytes in alveoli.We also identified SARS-CoV-2 RNA in respiratory tract tissues,including trachea,bronchus and lung;and viruses were also re-isolated from oropharyngeal swabs,bronchus and lung,respectively.Furthermore,we demonstrated that neutralizing antibodies generated from the primary infection could protect the Rhesus macaques from a second-round challenge by SARS-CoV-2.The non-human primate model that we established here provides a valuable platform to study SARS-CoV-2 pathogenesis and to evaluate candidate vaccines and therapeutics. | Chao Shan Yan-Feng Yao Xing-Lou Yang Yi-Wu Zhou Ge Gao Yun Peng Lian Yang Xue Hu Jin Xiong Ren-Di Jiang Hua-Jun Zhang Xiao-Xiao Gao Cheng Peng Juan Min Ying Chen Hao-Rui Si Jia Wu Peng Zhou Yan-Yi Wang Hong-Ping Wei Wei Pang Zheng-Fei Hu Long-Bao Lv Yong-Tang Zheng Zheng-Li Shi Zhi-Ming Yuan | 2020 | Cell Research2020,30,8: | 19 |
| 7 | Experimental primates and non-human primate(NHP) models of human diseases in China: current status and progress显示文摘Non-human primates(NHPs) are phylogenetically close to humans, with many similarities in terms of physiology, anatomy, immunology, as well as neurology, all of which make them excellent experimental models for biomedical research. Compared with developed countries in America and Europe, China has relatively rich primate resources and has continually aimed to develop NHPs resources. Currently, China is a leading producer and a major supplier of NHPs on the international market. However, there are some deficiencies in feeding and management that have hampered China's growth in NHP research and materials. Nonetheless, China has recently established a number of primate animal models for human diseases and achieved marked scientific progress on infectious diseases, cardiovascular diseases, endocrine diseases, reproductive diseases, neurological diseases, and ophthalmic diseases, etc. Advances in these fields via NHP models will undoubtedly further promote the development of China's life sciences and pharmaceutical industry, and enhance China's position as a leader in NHP research. This review covers the current status of NHPs in China and other areas, highlighting the latest developments in disease models using NHPs, as well as outlining basic problems and proposing effective countermeasures to better utilize NHP resources and further foster NHP research in China. | Xiao-Liang ZHANG Wei PANG Xin-Tian HU Jia-Li LI Yong-Gang YAO Yong-Tang ZHENG | 2014 | Zoological Research2014,35,6: | 16 |
| 8 | BH3-only proteins target BCL-xL/MCL-1,not BAX/BAK,to initiate apoptosis显示文摘It has been widely accepted that mitochondria-dependent apoptosis initiates when select BH3-only proteins(BID,BIM,etc.)directly engage and allosterically activate effector proteins BAX/BAK.Here,through reconstitution of cells lacking all eight pro-apoptotic BH3-only proteins,we demonstrate that all BH3-only proteins primarily target the anti-apoptotic BCL-2 proteins BCL-xL/MCL-1,whose simultaneous suppression enables membrane-mediated spontaneous activation of BAX/BAK.BH3-only proteins*apoptotic activities correlate with affinities for BCL-xL/MCL1 instead of abilities to directly activate BAX/BAK.Further,BID and BIM do not distinguish BAX from BAK or accelerate BAX/BAK activation following inactivation of BCL-xL/MCL-1.Remarkably,death ligandinduced apoptosis in cells lacking BH3-only proteins and MCL-1 is fully restored by BID mutants capable of neutralizing BCL-xL,but not direct activation of BAX/BAK.Taken together,our findings provide a'Membrane-mediated Permissive'model,in which the BH3-only proteins only indirectly activate BAX/BAK by neutralizing the anti-apoptotic BCL-2 proteins,and thus allowing BAX/BAK to undergo unimpeded,spontaneous activation in the mitochondrial outer membrane milieu,leading to apoptosis initiation. | Kai Huang Katelyn L.O'Neill Jian Li Wei Zhou Na Han Xiaming Pang Wei Wu Lucas Struble Gloria Borgstahl Zhaorui Liu Liqiana Zhang Xu Luo | 2019 | Cell Research2019,29,11: | 16 |
| 9 | Kanglexin,a novel anthraquinone compound,protects against myocardial ischemic injury in mice by suppressing NLRP3 and pyroptosis显示文摘Pyroptosis is a form of inflammatory cell death that could be driven by the nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3(NLRP3)inflammasome activation following myocardial infarction(MI).Emerging evidence suggests the therapeutic potential for ameliorating MI-induced myocardial damages by targeting NLRP3 and pyroptosis.In this study,we investigated the myocardial protection effect of a novel anthraquinone compound(4,5-dihydroxy-7-methyl-9,10-anthraquinone-2-ethyl succinate)named Kanglexin(KLX)in vivo and in vitro.Male C57BL/6 mice were pre-treated either with KLX(20,40 mg·kg^?1per day,intragastric gavage)or vehicle for 7 consecutive days prior to ligation of coronary artery to induce permanent MI.KLX administration dose-dependently reduced myocardial infarct size and lactate dehydrogenase release and improved cardiac function as compared to vehicle-treated mice 24 h after MI.We found that MI triggered NLRP3 inflammasome activation leading to conversion of interleukin-1β(IL-1β)and IL-18 into their active mature forms in the heart,which could expand the infarct size and drive cardiac dysfunction.We also showed that MI induced pyroptosis,as evidenced by increased DNA fragmentation,mitochondrial swelling,and cell membrane rupture,as well as increased levels of pyroptosis-related proteins,including gasdermin D,N-terminal GSDMD,and cleaved caspase-1.All these detrimental alterations were prevented by KLX.In hypoxia-or lipopolysaccharide(LPS)-treated neonatal mouse ventricular cardiomyocytes,we showed that KLX(10μM)decreased the elevated levels of terminal deoxynucleotidyl transferase dUTP nick end labeling-and propidium iodide-positive cells,and pyroptosis-related proteins.We conclude that KLX prevents MI-induced cardiac damages and cardiac dysfunction at least partly through attenuating NLRP3 and subsequent cardiomyocyte pyroptosis,and it is worthy of more rigorous investigations for its potential for alleviating ischemic heart disease. | Yu Bian Xin Li Ping Pang Xue-ling Hu Shu-ting Yu Yi-ning Liu Xin Li Ning Wang Jin-hui Wang Wei Xiao Wei-jie Du Bao-feng Yang | 2020 | Acta Pharmacologica Sinica2020,41,3: | 15 |

| 11 | 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 |
| 12 | Clinical evaluation of surgery-induced astigmatism in cataract surgery using 2.2 mm or 1.8 mm clear corneal micro-incisions显示文摘● AIM: To evaluate corneal astigmatism after phacoemulsification using 2.2 mm or 1.8 mm clear corneal micro-incisions and its effects on visual function.● METHODS: Sixty cases(60 eyes) with cataract were randomly divided into groups A(n=30) and B(n=30) respectively underwent 2.2 mm and 1.8 mm clear corneal tunnel incision phacoemulsification combined with folding intraocular lens implantation from the time direction of 11:00. On day 1 and at 1, 4, and 6wk after operation, patients' vision was measured and both the corneal curvature and corneal thickness(CT) were recorded using Pentacam. ● RESULTS: The measured surgery-induced astigmatism(SIA) in both groups A and B peaked on day 1 after operation, and then gradually decreased and eventually stabilized in week 4. No statistically significant difference was found in corneal astigmatism between two groups(P>0.05). The measured corneal astigmatism at 4wk and 6wk postoperatively were 0.28±0.09 D and 0.27±0.10 D for groups A and 0.27±0.09 D and 0.25±0.10 D for groups B without statistically significant difference(P>0.05). In addition, no significant differences in visual acuity and CT were found between groups A and B before or after operation.● CONCLUSION: Both 2.2 mm and 1.8 mm micro-incision cataract surgeries result in relatively small SIA with no difference in visual function and corneal astigmatism between two surgery approaches. Thus, the two types of surgical systems are safe and efficient for cataract treatment, by which satisfactory uncorrected visual acuity can be regained early postoperatively. | Jun Yang Xiu Wang Hong Zhang Yi Pang Rui-Hua Wei | 2017 | International Journal of Ophthalmology(English edition)2017,10,1: | 12 |

| 14 | Overexpression of the tonoplast aquaporin AtTIP5;1 conferred tolerance to boron toxicity in Arabidopsis显示文摘Boron (B) toxicity to plants is responsible for low crop productivity in many regions of the world. Here we report a novel and effective means to alleviate the B toxicity to plants under high B circumstance. Functional characterization of AtTIP5;1, an aquaporin gene, re-vealed that overexpression of AtTIP5;1 (OxAtTIP5;1) in Arabidopsis significantly increased its tolerance to high B toxicity. Compared to wild-type plants, OxAtTIP5;1 plants exhibited longer hypocotyls, accelerated development, increased silique production under high B treatments. GUS staining and quantitative RT-PCR (qRT-PCR) results demonstrated that the expression of AtTIP5;1 was induced by high B concentration treatment. Subcellular localization analysis revealed that the AtTIP5;1-GFP fusion protein was localized on the tonoplast membrane, which was consistent with the prediction based on bioinformatics. Taken together, our results suggest that AtTIP5;1 is in-volved in B transport pathway possibly via vacuolar compartmentation for B, and that overexpression of AtTIP5;1 in plants may provide an effective way to overcome the problem resulting from high B concentration toxicity. | Yongqi Pang, Lijuan Li, Fei Ren, Pingli Lu, Pengcheng Wei, Jinghui Cai, Lingguo Xin, Juan Zhang, Jia Chen, Xuechen Wang State Key Laboratory of Plant Physiology and Biochemistry, College of Biological Sciences, China Agricultural University, Beijing 100193, China | 2010 | Journal of Genetics and Genomics2010,37,6: | 11 |
| 15 | Lentivirual vector-mediated doxycycline-inducible iASPP gene targeted RNA interference in hepatocellular carcinoma显示文摘Background and Objective:iASPP, an inhibitory member of the apoptosis-stimulating proteins of p53 (ASPP) family, has been found to be up-regulated in various human tumor types.This study was to construct an efficient doxycycline-regulated, lentiviral vector-mediated knockdown system for iASPP that will allow for inducible down-regulation of iASPP gene expression and preliminary functional analysis.Methods:A pair of complementary oligos with hairpin structures targeting the iASPP gene and a negative control were synthesized, then ligated with pLVTHM vector and sequenced.The fragment containing the shRNA cassette was cloned to pLVCT-tTR-KRAB plasmid.The recombinant vectors were co-transfected with viral packaging mix into 293T cells, and viral supernatant was harvested to determine the titer.After treatment with or without doxycycline, HepG2 cells infected with virus were harvested and the expression of iASPP was detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis.Its effects on tumor growth were characterized using MTS assay, soft agar colony formation, and flow cytometry analysis.Results:The lentiviral vector expressing shRNA that targets to the oncogene iASPP was constructed successfully.HepG2 infected with the lentivirus expressing shRNA against iASPP inhibited the expression of iASPP in the presence of doxycycline, which resulted in the repression of tumor cell proliferation and anchorage-independent growth potential.Conclusions:The lentiviral vector-mediated tet-on system demonstrates efficient and inducible knockdown of iASPP in hepatocellular carcinoma cells.iASPP gene may be involved in tumorigenesis and progression of human tumors. | Ming-Shu Pang Xia Chen Bin LU Jian Zhao Bo-Hua Li Yu-Quan Wei Ya-Jun GUO | 2010 | Chinese Journal of Cancer2010,29,9: | 11 |
| 16 | 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 |
| 17 | Surface pollen assemblages of human-disturbed vegetation and their relationship with vegetation and climate in Northeast China显示文摘Pollen assemblages of 53 surface pollen samples from farmlands and wastelands in Northeast China were analyzed. Tree pollen percentages were usually higher than 30%, with Pinus (26.9%), Quercus (0.9%), Betula (0.9%) and Populus (0.7%) as the major types, and herb pollen percentages were usually higher than 50%, with weedy Poaceae (8.7%), Chenopodiaceae (7.1%), Artemisia (1.9%) and Compositae (3.5%) as the major taxa. Thus, the pollen assemblages were consistent with the regional vegetation compositions. However, there were differences in pollen assemblages among regions, especially among different geomorphological units. For example, in the mountains, there were more types of tree pollen and higher total percentages (average 42%) than in other areas, while cereal pollen percentages were lowest (11.2%). In the hills and high plains, herbs made up more than 60% of the pollens, with cereals (average 53.6%) the dominant type. In the low plains, pollen types were similar to those in the hills and high plains, but total pollen concentrations and the proportion of Concentricystes were much higher, while cereal pollen percentages were slightly lower (average 41.6%). Pollen assemblages in different land use types also differed. For example, in farmland, cereal pollen percentages were more than 40% and Chenopodiaceae was usually less than 2.5%, while in wasteland, weedy Poaceae was usually less than 10% and Chenopodiaceae was usually higher than 25%. Total pollen concentrations in farmland (average 3909 grains/g) were much lower than in wasteland (average 15074 grains/g). Redundancy analysis revealed that pollen assemblages were significantly negatively correlated with mean annual temperature (-0.73) and July mean temperature (-0.81) and significantly positively correlated with mean annual precipitation (0.48), indicating that pollen assemblages in the artificial or human-disturbed vegetation reflect regional climate well. Comparison of pollen assemblages in different areas of northern China showed that pollen concentrations reflect the intensities of human impact to some degree. For example, pollen concentrations decrease as human impacts increase in intensity. The cereal pollen proportions in farmland differed by area. In Northeast China, cereal pollen proportions were distinctly higher than in most other areas of northern China, suggesting differences in planting habits and climate. | LI ManYue LI YueCong XU QingHai PANG RuiMing DING Wei ZHANG ShengRui HE ZhiGuo | 2012 | Chinese Science Bulletin2012,57,5: | 10 |
