1Soil Microbial Community Structure in Diverse Land Use Systems:A Comparative Study Using Biolog,DGGE,and PLFA Analyses显示文摘Biolog,16S rRNA gene denaturing gradient gel electrophoresis(DGGE) ,and phospholipid fatty acid(PLFA) analyses were used to assess soil microbial community characteristics in a chronosequence of tea garden systems(8-,50-,and 90-year-old tea gardens) ,an adjacent wasteland,and a 90-year-old forest. Biolog analysis showed that the average well color development(AWCD) of all carbon sources and the functional diversity based on the Shannon index decreased(P < 0.05) in the following order:wasteland > forest > tea garden. For the DGGE analysis,the genetic diversity based on the Shannon index was significantly lower in the tea garden soils than in the wasteland. However,compared to the 90-year-old forest,the tea garden soils showed significantly higher genetic diversity. PLFA analysis showed that the ratio of Gram positive bacteria to Gram negative bacteria was significantly higher in the tea garden soils than in the wasteland,and the highest value was found in the 90-year-old forest. Both the fungal PLFA and the ratio of fungi to bacteria were significantly higher in the three tea garden soils than in the wasteland and forest,indicating that fungal PLFA was significantly affected by land-use change. Based on cluster analysis of the soil microbial community structure,all three analytical methods showed that land-use change had a greater effect on soil microbial community structure than tea garden age.XUE Dong YAO Huai-Ying GE De-Yong HUANG Chang-Yong 2008Pedosphere2008,18,5:56

4Genetic diversity and construction of core collection in Chinese wheat genetic resources显示文摘Genetic diversity among 5029 accessions representing a proposed Chinese wheat core collection was analyzed using 78 pairs of fluorescent microsatellite (SSR) primers mapped to 21 chromosomes. A stepwise hierarchical sampling strategy with priority based on 4×105 SSR data-points was used to construct a core collection from the 23090 initial collections. The core collection consisted of 1160 accessions, including 762 landraces, 348 modern varieties and 50 introduced varieties. The core ac-counts for 23.1% of the 5029 candidate core accessions and 5% of the 23090 initial collections, but retains 94.9% of alleles from the candidate collections and captures 91.5% of the genetic variation in the initial collections. These data indicate that it is possible to maintain genetic diversity in a core collection while retaining fewer accessions than the accepted standard, i.e., 10% of the initial collections captured more than 70% of their genetic diversity. Estimated genetic representation of the core con-structed by preferred sampling (91.5%) is much higher than that by random sampling (79.8%). Both mean genetic richness and genetic diversity indices of the landraces were higher than those of the modern varieties in the core. Structure and principal coordinate analysis revealed that the landraces and the modern varieties were two relatively independent subpopulations. Strong genetic differentiation associated with ecological environments has occurred in the landraces, but was relatively weak in the modern cultivars. In addition, a mini-core collection was constructed, which consisted of 231 accessions with an estimated 70% representation of the genetic variation from the initial collections. The mini-core has been distributed to various research and breeding institutes for detailed phenotyping and breeding of genetic introgression lines.HAO ChenYang DONG YuChen WANG LanFen YOU GuangXia ZHANG HongNa GE HongMei JIA JiZeng ZHANG XueYong 2008Chinese Science Bulletin2008,53,10:27
5Networked Control Systems:A Survey of Trends and Techniques显示文摘Networked control systems are spatially distributed systems in which the communication between sensors, actuators,and controllers occurs through a shared band-limited digital communication network. Several advantages of the network architectures include reduced system wiring, plug and play devices,increased system agility, and ease of system diagnosis and maintenance. Consequently, networked control is the current trend for industrial automation and has ever-increasing applications in a wide range of areas, such as smart grids, manufacturing systems,process control, automobiles, automated highway systems, and unmanned aerial vehicles. The modelling, analysis, and control of networked control systems have received considerable attention in the last two decades. The ‘control over networks’ is one of the key research directions for networked control systems. This paper aims at presenting a survey of trends and techniques in networked control systems from the perspective of ‘control over networks’, providing a snapshot of five control issues: sampled-data control, quantization control, networked control, event-triggered control, and security control. Some challenging issues are suggested to direct the future research.Xian-Ming Zhang Qing-Long Han Xiaohua Ge Derui Ding Lei Ding Dong Yue Chen Peng 2020IEEE/CAA Journal of Automatica Sinica2020,7,1:25
6Relationship between cytokines gene polymorphism and susceptibility to hepatitis B virus intrauterine infection显示文摘Background The influences of genomic background are confirmed in more diseases. Immunologic tolerance after intrauterine infection of hepatitis B virus is considered to occur in T cells. Cytokines work effectively in eliminating virus by immune system after hepatitis B virus infection. To explore the relationship between cytokines (tumor necrosis factor-α, interferon-γ, interleukin-4 and interleukin-10), which expressed abnormal quantity in the peripheral blood to intrauterine hepatitis B virus infectious children, gene single nucleotide polymorphism (SNP) and susceptibility to hepatitis B virus intrauterine infection. Methods This is a cross sectional study of molecular clinical epidemiology. The subjects in this study were selected from outpatients of hepatitis B vaccine follow-up special clinics of our hospital in the period. According to intrant criteria, the high risk children of hepatitis B virus (HBV) intrauterine infection were divided into immune failure group (group Ⅰ); and immune effective group (group Ⅱ) and non high risk children belonged to the control group. Four gene SNP sites of TNF-α -238, IFN-γ +874, IL-4 -590 and IL-10 -1082 were determined by real-time quantitative fluorescent polymerase chain reaction (PCR). Results The significant differences of TNF-α -238 A allele frequency were found between group Ⅰ and groupⅡ (χ2=6.797,P<0.05) and between groupⅠ and the control group (χ2=9.513,P<0.05). No evident differences of TNF-α -238 A were found between group Ⅱ and control group (χ2=0.047,P>0.05); the significant differences of IFN-γ +874 A allele frequency were found between groupⅠ and groupⅡ(χ2=7.238,P<0.05), and between groupⅠ and the control group (χ2=5.199,P<0.05). No evident differences were found between groupⅡ and the control group (χ2=0.602,P>0.05); the significant differences of IL-4 -590 C/T allele frequency were not found between groupⅠand group Ⅱ(χ2=0.632,P>0.05), also groupⅠ and the control group (χ2=0.584,P>0.05), and the groupⅡ and the control group (χ2=0.004,P>0.05)respectively; The significant differences of IL-10 -1082 G allele frequency were found between groupⅡ and groupⅠ (χ2=10.359,P<0.001), and between groupⅡ and the controls (χ2=35.418,P<0.001), but the significant differences were not found between groupⅠand the control group (χ2=1.759,P>0.05). Conclusions This study suggested the possibility that the TNF-α -238 A allele and IFN-γ +874 A allele were associated with HBV intrauterine infection. There was no evident relationship between IL-4 -590 C/T allele SNP and susceptibility to HBV intrauterine infection, but the IL-10 -1082 G allele was associated with preventive efficacy to HBV intrauterine infection.ZHU Qi-rong GE Yan-ling GU Shao-qing YU Hui WANG Jian-she GU Xin-huan FEI Lin-e DONG Zuo-quan 2005Chinese Medical Journal2005,,19:21

8Over-expression of Metastasis-associated in Colon Cancer-1 (MACC1) Associates with Better Prognosis of Gastric Cancer Patients显示文摘Objective: The aim of this study was to detect metastasis-associated in colon cancer-1 (MACC1) expression in Chinese gastric cancer and analyze the relationship between MACC1 expression and postoperative survival. Methods: The expression of MACC1 and c-MET protein in a sample of 128 gastric cancer tissues was detected by immunohistochemistry. A retrospective cohort study on the prognosis was carried out and data were collected from medical records. Results: The positive rate of MACC1 protein expression in gastric cancer was 47.66%, higher than that in adjacent noncancerous mucosa (P<0.001). MACC1 protein expression was not related to the clinicopathological variables involved. Kaplan-Meier analysis revealed that the survival of MACC1 positive group tended to be better than that of MACC1 negative group, particularly in patients with stage III carcinoma (P=0.032). Cox regression analysis revealed that MACC1 protein over-expression in gastric cancer tended to be a protective factor with hazard ratio of 0.621 (P=0.057). Immunohistochemical analysis showed that the positive rate of c-MET protein expression was much higher in cases with positive MACC1 expression in gastric cancer (P=0.002), but P53 expression was not associated with MACC1 expression. Conclusion: MACC1 over-expression implies better survival and may be an independent prognostic factor for gastric cancer in Chinese patients.Shao-hua Ge Xiao-jiang Wu Xiao-hong Wang Xiao-fang Xing Lian-hai Zhang Yu-bing Zhu Hong Du Bin Dong Ying Hu Jia-fu Ji 2011Chinese Journal of Cancer Research2011,23,2:19
9Effectiveness of 5-flurouracil-based neoadjuvant chemotherapy in locally-advanced gastric/gastroesophageal cancer:A meta-analysis显示文摘AIM:To investigate the effectiveness of 5-flurouracilbased neoadjuvant chemotherapy(NAC) for gastroesophageal and gastric cancer by meta-analysis.METHODS:MEDLINE and manual searches were performed to identify all published randomized controlled trials(RCTs) investigating the efficacy of the flurouracilbased NAC for gastroesophageal and gastric cancer,and RCTs of NAC for advanced gastroesophageal and gastric cancer vs no therapy before surgery.Studies that included patients with metastases at enrollment were excluded.Primary endpoint was the odds ratio(OR) for improving overall survival rate of patients with gastroesophageal and gastric cancer.Secondary endpoints were the OR of efficiency for down-staging tumor and increasing R0 resection in patients with gas-troesophageal and gastric cancer.Safety analyses were also performed.The OR was the principal measurement of effect,which was calculated as the treatment group(NAC plus surgery) vs control group(surgery alone) and was presented as a point estimate with 95% confidence intervals(CI).All calculations and statistical tests were performed using RevMan 5.1 software.RESULTS:Seven RCTs were included for the analysis.A total of 1249 patients with advanced gastroesophageal and gastric cancer enrolled in the seven trials were divided into treatment group(n = 620) and control group(n = 629).The quality scores of the RCTs were assessed according to the method of Jadad.The RCT quality scores ranged from 2 to 7(5-point scale),with a mean of 3.75.The median follow-up time in these studies was over 3 years.The meta-analysis showed that NAC improved the overall survival rate(OR 1.40,95%CI 1.11-1.76;P = 0.005),which was statistically significant.The 3-year progression-free survival rate was significantly higher in treatment group than in control group(37.7% vs 27.3%)(OR 1.62,95%CI 1.21-2.15;P = 0.001).The tumor down-stage rate was higher in treatment group than in control group(55.76% vs 41.38%)(OR 1.77,95%CI 1.27-2.49;P = 0.0009) and the R0 resection rate of the gastroesophageal and gastric cancer was higher in treatment group than in control group(75.11% vs 68.56%)(OR 1.38,95%CI 1.03-1.85;P = 0.03),with significant differences.No obvious safety concerns about mortality and complications were raised in these trials.There were no statistically significant differences in perioperative mortality(5.08% vs 4.86%)(OR 1.05,95%CI 0.57-1.94;P = 0.87 fixed-effect model) and in the complication rate between the two groups(13.25% vs 9.66%)(OR 1.40,95%CI 0.91-2.14;P = 0.12 fixed-effect model).Trials showed that patients from Western countries favored NAC compared with those from Asian countries(OR 1.40,95%CI 1.07-1.83).Monotherapy was inferior tomultiple chemotherapy(OR 1.40,95%CI 1.07-1.83).Intravenous administration of NAC was more advantageous than oral route(OR 1.41,95%CI 1.09-1.81).CONCLUSION:Flurouracil-based NAC can safely improve overall survival rate of patients with gastroesophageal/gastric cancer.Additionally,NAC can down the tumor stage and improve R0 resection.Lei Ge Hai-Jiang Wang Dong Yin Cheng Lei Jin-Feng Zhu Xiao-Hui Cai Guo-Qing Zhang 2012World Journal of Gastroenterology2012,18,48:19

12Effect of Kuanxiong Aerosol(宽胸气雾剂)on Patients with Angina Pectoris:A Non-inferiority Multi-center Randomized Controlled Trial显示文摘Objective: To evaluate the effect and safety of Kuanxiong Aerosol(宽胸气雾剂, KA) on patients with angina pectoris. Methods: Block randomization was performed to randomly allocate 750 patients into KA(376 cases) and control groups(374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA(0.6 m L per spray). The control group received 1 sublingual nitroglycerin tablet(NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment(1, 2, 3, 4, 5, and >5 min). Logistic regression analysis was performed to observe the factors influencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society(CCS) classes of angina. Results: The 5-min remission rates in the KA and control groups were not significantly different(94.41% vs. 90.64%, P>0.05). The angina CCS class significantly influenced the rate of remission (95% confidence interval = 0.483–0.740, P<0.01). In the CCS subgroup analysis, the 3-and 5-min remission rates for KA and NT were similar in the CCSⅠ and Ⅳ subgroups(P>0.05), while they were significantly better for KA in the CCSⅡ and Ⅲ subgroups(P<0.05 or P<0.01). Furthermore, the incidence of adverse reactions was significantly lower in the KA group than in the control group for the CCSⅡ and Ⅲ subgroups(9.29% vs. 26.22%, 10.13% vs. 20.88%, P<0.05 or P<0.01). Conclusions: KA is not inferior to NT in the remission of angina. Furthermore, in CCSⅡ and Ⅲ patients, KA is superior to NT, with a lower incidence of adverse reactions.YANG Qiao-ning BAI Rui-na DONG Guo-ju GE Chang-jiang ZHOU Jing-min HUANG Li HE Yan WANG Jun REN Ai-hua HUANG Zhan-quan ZHU Guang-li LU Shu XIONG Shang-quan XIAN Shao-xiang ZHU Zhi-jun SHI Da-zhuo LU Shu-zheng LI Li-zhi CHEN Ke-ji 2018Chinese Journal of Integrative Medicine2018,24,5:15
13Traditional Chinese medicine in COVID-19显示文摘COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2(SARSCo V-2)has spread across the globe,posing an enormous threat to public health and safety.Traditional Chinese medicine(TCM),in combination with Western medicine(WM),has made important and lasting contributions in the battle against COVID-19.In this review,updated clinical effects and potential mechanisms of TCM,presented in newly recognized three distinct phases of the disease,are summarized and discussed.By integrating the available clinical and preclinical evidence,the efficacies and underlying mechanisms of TCM on COVID-19,including the highly recommended three Chinese patent medicines and three Chinese medicine formulas,are described in a panorama.We hope that this comprehensive review not only provides a reference for health care professionals and the public to recognize the significant contributions of TCM for COVID-19,but also serves as an evidence-based in-depth summary and analysis to facilitate understanding the true scientific value of TCM.Ming Lyu Guanwei Fan Guangxu Xiao Taiyi Wang Dong Xu Jie Gao Shaoqin Ge Qingling Li Yuling Ma Han Zhang Jigang Wang Yuanlu Cui Junhua Zhang Yan Zhu Boli Zhang 2021Acta Pharmaceutica Sinica B2021,11,11:14
14Toripalimab combined with lenvatinib and GEMOX is a promising regimen as first-line treatment for advanced intrahepatic cholangiocarcinoma:a single-center,single-arm,phase 2 study显示文摘Advanced intrahepatic cholangiocarcinoma(ICC)has a dismal prognosis.Here,we report the efficacy and safety of combining toripalimab,lenvatinib,and gemcitabine plus oxaliplatin(GEMOX)as first-line therapy for advanced ICC.Thirty patients with pathologically confirmed advanced ICC received intravenous gemcitabine(1 g/m2)on Days 1 and 8 and oxaliplatin(85 mg/m2)Q3W for six cycles along with intravenous toripalimab(240 mg)Q3W and oral lenvatinib(8 mg)once daily for one year.The expression of programmed death-ligand 1(PD-L1)and genetic status was investigated in paraffin-embedded tissues using immunohistochemistry and whole-exome sequencing(WES)analysis.The primary endpoint was the objective response rate(ORR).Secondary outcomes included safety,overall survival(OS),progression-free survival(PFS),disease control rate(DCR)and duration of response(DoR).As of July 1,2022,the median follow-up time was 23.5 months,and the ORR was 80%.Twenty-three patients achieved partial response,and one achieved complete response.Patients(21/30)with DNA damage response(DDR)-related gene mutations showed a higher ORR,while patients(14/30)with tumor area positivity≥1(PD-L1 staining)showed a trend of high ORR,but without significant difference.The median OS,PFS,and DoR were 22.5,10.2,and 11.0 months,respectively.The DCR was 93.3%.Further,56.7%of patients experienced manageable grade≥3 adverse events(AEs),commonly neutropenia(40.0%)and leukocytopenia(23.3%).In conclusion,toripalimab plus lenvatinib and GEMOX are promising first-line regimens for the treatment of advanced ICC.A phase-III,multicenter,double-blinded,randomized study to validate our findings was approved by the National Medical Products Administration(NMPA,No.2021LP01825).Guo-Ming Shi Xiao-Yong Huang Dong Wu Hui-Chuan Sun Fei Liang Yuan Ji Yi Chen Guo-Huan Yang Jia-Cheng Lu Xian-Long Meng Xin-Ying Wang Lei Sun Ning-Ling Ge Xiao-Wu Huang Shuang-Jian Qiu Xin-Rong Yang Qiang Gao Yi-Feng He Yang Xu Jian Sun Zheng-Gang Ren Jia Fan Jian Zhou 2023Signal Transduction and Targeted Therapy2023,8,4:12
15Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12
16The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects.

18Association Between Diurnal Temperature Range and Respiratory Tract Infections显示文摘Objective This study aimed to assess the association between emergency-room visits for respiratory tract infection (RTI) with diurnal temperature range (DTR), a weather parameter closely associated with urbanization and global climate change. Methods We conducted a semiparametric time-series analysis to estimate the percentage increase in emergency-room visits for RTI associated with changes in DTR after adjustment for daily weather conditions (temperature and relative humidity) and outdoor air pollution. Results DTR was significantly associated with daily emergency-room visits for RTI. An increase of 1 °C in the current-day (L0) and in the 2-day moving average (L01) DTR corresponded to a 0.94% [95% confidence interval (CI), 0.34%-1.55%] and 2.08% (95% CI, 1.24%-2.93%) increase in emergency-room visits for RTI, respectively. Conclusion DTR was associated with increased risk of RTI. More studies are needed to understand the impact of DTR on respiratory health.GE Wen Zhen XU Feng ZHAO Zhuo Hui ZHAO Jin Zhuo KAN Hai Dong 2013Biomedical and Environmental Sciences2013,26,3:10
19Power Matching and Energy Efficiency Improvement of Hydraulic Excavator Driven with Speed and Displacement Variable Power Source显示文摘Mobile machinery energy efficiency and emission pollution are the national and worldwide issues. This paper contributes in solving these problems by applying a speed variable power source. Unfortunately, almost all of the speed variable systems have the dynamic response problem when the motor starts with full load or heavy load. To address this problem, a hydraulic accumulator is used to balance the load of the power source for assisting starting of the motor and a matching method combined with speed and displacement control of the pump is proposed to improve the energy efficiency and dynamic performance simultaneously under different working conditions. Also, the power source/valve combined control strategy of an independent metering system is designed to realize flow matching of the whole system. Firstly, a test system is established to study the dynamic performance and energy efficiency of the speed variable power source with an auxiliary accumulator. Working performance and energy consumption of the power source under different rotating speeds and different loads are studied. And then, the hydraulic excavator test rig with the proposed system is constructed. Furthermore, the working performance of the excavator with the speed-fixed and speed-variable strategy are studied comparatively. Results show that, compared with fixed-speed strategy, the electric power consumption during the idle period and partial load condition can be reduced about 2.05 kW and 1.37 kW. The energy efficiency of speed variable power source is about 40%-71%, which is higher than that of the fixed-speed power source by 3%–10%.Lei Ge Long Quan Xiaogang Zhang Zhixin Dong Jing Yang 2019Chinese Journal of Mechanical Engineering2019,32,6:10
20Ginkgo Huolinhensis sp.nov.from the Lower Cretaceous of Huolinhe Coal Field,Inner Mongolia,China显示文摘A new species,Ginkgo huolinhensis sp.nov.,with well-preserved cuticle from the Lower Cretaceous,Huolinhe Formation of Huolinhe Coal Field in Inner Mongolia,China,was studied morphologically and anatomically.The main characters of the new species are found in the leaves which are deeply dissected with narrow lobes,trichomes developed on both upper and lower epidermal cells,a media papilla developed on the periclinal walls for each cell in upper cuticle,and no trichomes on the cuticle of the petioles.These characters of G.huolinhensis sp.nov.distinguish from the known species of Ginkgo previously reported.This study of the new species is beneficial for the taxonomic research of fossil Ginkgo,and should be helpful for a better understanding the paleoenvironment of Ginkgo living in northeastern China during the Early Cretaceous.DONG Man SUN Ge 2012Acta Geologica Sinica(English Edition)2012,86,1:9
