| 1 | Sedum alfredii H:A new Zn hyperaccumulating plant first found in China显示文摘Field survey and greenhouse experiments were carried out to identify and characterize zinc (Zn) uptake and accumulation by a new Zn hyperaccumulating plant species (Sedum alfredii Hance) native to China. Zinc concentration in the shoots of Sedum alfredii Hance grown on an ancient mined area ranged from 4134 to 5000 mg/kg, with a mean of 4515 mg/kg. It suggests that Sedum alfredii could not only grow on heavily Pb/Zn contaminated soils, but also could accumulate extraordinarily high concentration of Zn. Under nutrient solution culture conditions, Sedum alfredii Hance grew healthy at Zn supplying levels from 0.006 to 240 mg · L-1. Zinc concentration in the shoots increased with external Zn levels increasing. The Zn concentration and accumulation in the shoots reached the highest at Zn supply level of SO mg/L, with 19.67 g/kg and 19.83 nig/plant, respectively. All the results showed that Sedum alfredii Hance is a new Zn hyperaccumulating plant.

| 4 | The M5.0 Suining-Tongnan (China) earthquake of 31 January 2010:A destructive earthquake occurring in sedimentary cover显示文摘Usually, only crystalline basement is strong enough to store the massive strain energy that can be released in a damaging earthquake. By contrast, sedimentary cover is weak, because of its relatively high porosity and fluids. Therefore, it generally cannot accumulate enough energy for strong earthquakes. On January 31, 2010, a M5.0 earthquake occurred near the border of Suining and Tongnan in China. It excited strong short-period Rayleigh waves Rg, indicative of its shallow focal depth. The focal depth is constrained to less than 4 km, most probably in the range of 1-3 km, by modeling amplitude dependence on the frequency and waveforms of teleseismic depth phases (pP, sP). Because the local Mesozoic sedimentary cover is about 6 km thick, this earthquake should have occurred in the sedimentary cover. Though some shallow earthquakes with magnitudes up to M4 occur in Paleozoic sediments, this earthquake is the first M5 event studied in Mesozoic sedimentary cover. This event provides a rare opportunity to study seismogenic processes of damaging earthquakes in sedimentary basins. | LUO Yan NI SiDao ZENG XiangFang XIE Jun CHEN Yong LONG Feng | 2011 | Chinese Science Bulletin2011，56，6： | 17 |
| 5 | Infantile hepatic hemangioendothelioma:A clinicopathologic study in a Chinese population显示文摘AIM:To investigate whether the clinicopathologic features of infantile hemangioendothelioma(IHE) of the liver in a Chinese population are similar to the features observed in other races.METHODS:The clinical data,radiological findings,histopathological changes and outcome of 12 cases of IHE diagnosed by the Department of Pathology,West China Hospital over the last 10 years were analyzed retrospectively.Immunohistochemical studies were carried out using antibodies against CD31,CD34,Factor Ⅷ,cytokeratin 8 and cytokeratin 18.RESULTS:The 12 patients were aged from fetal to 5 years(three males and nine females).The tumor was presented with different clinical manifestations,mainly as an asymptomatic,palpable,upper abdominal mass,except for the two fetuses who were detected antena-tally by ultrasound.In one patient,this presentation was accompanied by an initial severe pneumothorax.No symptoms of congestive heart failure were present and neither congenital abnormalities nor vascular tumors in the skin or other organs were found.Laboratory abnormalities included leukocytosis(40%),anemia(60%),thrombocytosis(60%),hyperbilirubinemia(16.7%),abnormal liver function(50%) and increased α-fetoprotein(80%).Based on radiological findings and gross specimens,the tumor presented as a solitary lesion or a multifocal space-occupying lesion.The tumor size ranged from 5.0 cm × 3.5 cm × 2.0 cm to 13.8 cm × 9.0 cm × 7.7 cm,and the 0.2-1.1 cm nodules were diffusely distributed within the multifocal tumor.Seven cases were surgically resected,three cases underwent biopsy and the two fetuses were aborted.Histologically,nine cases were classified as typeⅠ and three as type Ⅱ,presenting aggressive morphologic features,immature vessels,active mitosis and necrosis.An inflammatory component,predominantly eosinophilic granulocytes,sometimes obscured the nature of the tumor.Ten patients are alive after a follow-up of 1-9 years.Based on immunohistochemistry,the endothelial cells in all cases were positive for CD31,CD34 and polyclonal factor Ⅷ antigen,whereas the scattered hyperplasia bile ducts were positive for cytokeratin 8 and cytokeratin 18.CONCLUSION:The clinical manifestations of IHE are non-specific.There is no significant correlation between histological type and prognosis.The clinicopathologic features of IHE in Chinese patients may provide a clue to further evidence-based studies. | Zhang Zhang,Hui-Jiao Chen,Wen-Juan Yang,Hong Bu,Bing Wei,Xiao-Yu Long,Jing Fu,Rui Zhang,Yun-Bi Ni,Hong-Ying Zhang,Department of Pathology,West China Hospital,Sichuan University,Guoxuexiang 37,Chengdu 610041,Sichuan Province,China | 2010 | World Journal of Gastroenterology2010，16，36： | 16 |

| 7 | Primary intestinal malignant fibrous histiocytoma:two case reports显示文摘Malignant fibrous histiocytoma (MFH) occurs most commonly in the extremities and trunk, but rarely in the intestine. Here we report two cases of primary intestinal MFH. The first case was a 70-year old man admitted for recurrent right lower quadrant abdominal pain. At laparotomy, a tumor was found originating from the cecum, with a suspicious metastatic nodule on the surface of the right lobe of the liver. A right hemicolectomy was performed followed by an ileotransverse end-to-end anastomotic reconstruction. The second case was a 43-year old man with intussusceptions of the small intestine. An emergent laparotomy revealed 4 pedunculated masses in the small bowel and a partial resection of the small intestine was performed. Though the symptoms were not typical, based on histological and immunohistochemical studies, the patients were diagnosed as MFH of the intestine. They were not treated with chemotherapy or radiotherapy and both died within 3 mo. MFH of the intestine is an extremely rare neoplasm with an aggressive biological behavior. The pathogenesis of this disease has not been clarified to date. Complete surgical excision is preferred, adjuvant chemotherapy or radiotherapy may be advisable. | De-Liang Fu Feng Yang Ashish Maskay Jiang Long Chen Jin Xian-Jun Yu Jin Xu Zhong-Wen Zhou Quan-Xing Ni | 2007 | World Journal of Gastroenterology2007，13，8： | 13 |

| 9 | Analysis of gene expression profiles in pancreatic carcinoma by using cDNA microarray显示文摘OBJECTIVES: To survey the gene expression profiles in pancreatic carcinoma by using cDNA microarrayand detect target genes for further study.METHODS: Three mixed samples from 2 cases of normal pancreatic tissue and 4 cases ofmoderate-differentiated pancreatic carcinoma were studied by means of cDNA microarray consisting of18 000 genes.RESULTS: 1484 and 1353 different expressed genes were observed in two cancer samples respectively.We identified 455 genes altered with the same tendency in both samples, including 102 up-regulated and353 down-regulated genes. There were 274 known genes and 181 unknown genes; 27.8% and 52.0%genes respectively had an expression level in cancer that was 2-fold higher or lower than that in normalsamples. Tumor suppressor genes, growth factors and receptor genes, signal conduction genes,transcription factor genes were identified.CONCLUSIONS: cDNA microarray is an efficient and high-throughout method to investigate geneexpression profiles in pancreatic carcinoma. MBD1, EDG1 and gene hypermethylation mechanism wouldplay an important role in the pathogenesis of pancreatic carcinoma. | Xian-Jun Yu Jiang Long De-Liang Fu Qun-Hua Zhang Quan-Xin Ni the Center for Pancreatic Cancer, Department of General Surgery, Huashan Hospital, Fudan University, Shanghai 200040, China | 2003 | Hepatobiliary & Pancreatic Diseases International2003，2，3： | 8 |
| 10 | A detailed investigation of low latitude tweek atmospherics observed by the WHU ELF/VLF receiver:2.Occurrence features and associated ionospheric parameters显示文摘As a companion paper to Zhou RX et al.(2020),this study describes application of the automatic detection and analysis module to identify all the tweek atmospherics detectible in the WHU ELF/VLF receiver data collected at Suizhou station during the period of 3 February through 29 February 2016.Detailed analysis of the identified low-latitude tweek events reveals that the occurrence rate varies considerably—from 800 to 6000 tweeks per day,and exhibits a strong diurnal and local time dependence,the peak occurring before local midnight.The diurnal variation of identified tweeks was similar to that of the lightning data obtained by the World-Wide Lightning Location Network(WWLLN)..Estimates of the propagation distance and ionospheric reflection height of tweek atmospherics suggest that the majority(~92%)of the low latitude tweeks originate from the lightning activity within a radius of 4000 km and that they are very likely to reflect from the lower ionospheric D-region at the height range of 75–85 km.At these lower ionospheric reflection altitudes,~74%of the corresponding electron densities from the tweek spectral measurements are within 24.5–27.5 cm^-3.The daily variation of estimated D-region electron densities in the considered period(February 2016)also exhibits a small overall increasing trend from early to later in the month. | Juan Yi XuDong Gu Wen Cheng XinYue Tang Long Chen BinBin Ni RuoXian Zhou ZhengYu Zhao Qi Wang LiQing Zhou | 2020 | Earth and Planetary Physics2020，4，3： | 8 |
| 11 | Insight-HXMT:China's First X-Ray Astronomical Satellite显示文摘The Hard X-ray Modulation Telescope(HXMT) satellite is the first X-ray astronomical satellite in China. Utilizing the 'direct demodulation image reconstruction method', HXMT will perform broad band(1-250 keV) survey of large sky areas in scanning mode, which can result in source detection characterized with high sensitivity and spatial resolution. Point observation is another key working mode of HXMT, and is specified for observations of galactic bright sources like X-Ray Binary(XRB) and others. Additionally, HXMT also has a powerful capability developed for monitoring gamma-ray bursts, which is quite unique in the world due to its energy coverage of 200 keV-3 MeV and largest detection area. The HXMT satellite was launched by a Long March 4 B(LM-4 B) rocket from the Jiuquan Satellite Launch Center on June 15, 2017. The payloads onboard HXMT are a High Energy X-ray Telescope(HE), a Medium Energy X-ray Telescope(ME), a Low Energy X-ray Telescope(LE), and a Space Environment Monitor(SEM).This paper introduces the main technical aspects of the satellite, including scientific objectives, technical features, mission design, and system design. | PAN Teng NI Runli ZHANG Long HONG Bin GU Quanying LU Fangjun XU Yupeng | 2017 | Aerospace China2017，18，4： | 8 |
| 12 | A detailed investigation of low latitude tweek atmospherics observed by the WHU ELF/VLF receiver:Ⅰ. Automatic detection and analysis method显示文摘As a dispersive wave mode produced by lightning strokes, tweek atmospherics provide important hints of lower ionospheric(i.e., D-region) electron density. Based on data accumulation from the WHU ELF/VLF receiver system, we develop an automatic detection module in terms of the maximum-entropy-spectral-estimation(MESE) method to identify unambiguous instances of low latitude tweeks.We justify the feasibility of our procedure through a detailed analysis of the data observed at the Suizhou Station(31.57°N, 113.32°E) on17 February 2016. A total of 3961 tweeks were registered by visual inspection;the automatic detection method captured 4342 tweeks, of which 3361 were correct ones, producing a correctness percentage of 77.4%(= 3361/4342) and a false alarm rate of 22.6%(= 981/4342).A Short-Time Fourier Transformation(STFT) was also applied to trace the power spectral profiles of identified tweeks and to evaluate the tweek propagation distance. It is found that the fitting accuracy of the frequency–time curve and the relative difference of propagation distance between the two methods through the slope and through the intercept can be used to further improve the accuracy of automatic tweek identification. We suggest that our automatic tweek detection and analysis method therefore supplies a valuable means to investigate features of low latitude tweek atmospherics and associated ionospheric parameters comprehensively. | RuoXian Zhou XuDong Gu KeXin Yang GuangSheng Li BinBin Ni Juan Yi Long Chen FuTai Zhao ZhengYu Zhao Qi Wang LiQing Zhou | 2020 | Earth and Planetary Physics2020，4，2： | 7 |
| 13 | Effect of the number of positive lymph nodes and lymph node ratio on prognosis of patients after resection of pancreatic adenocarcinoma显示文摘BACKGROUND: The prognostic factors related to lymph node involvement [lymph node status, the number of positive lymph nodes, lymph node ratio (LNR)] and the number of nodes evaluated in patients with pancreatic adenocarcinoma after pancreatectomy are poorly defined.METHODS: A total of 167 patients who had undergone resection of pancreatic adenocarcinoma from February 2010 to August2011 were included in this study. Histological examination was performed to evaluate the tumor differentiation and lymph node involvement. Univariate and multivariate analyses were made to determine the relationship between the variables related to nodal involvement and the number of nodes and survival.RESULTS: The median number of total nodes examined was10 (range 0-44) for the entire cohort. The median number of total nodes examined in node-negative (pN 0) patients was similar to that in node-positive (pN 1) patients. Patients with pN 1 diseases had significantly worse survival than those with pN 0 ones (P=0.000). Patients with three or more positive nodes had a poorer prognosis compared with those with the negative nodes (P=0.000). The prognosis of the patients with negative nodes was similar to that of those with one to two positive nodes (P=0.114). The median survival of patients with an LNR≥0.4 was shorter than that of patients with an LNR <0.4 in thepN 1 cohort (P=0.014). No significance was found between the number of total nodes examined and the prognosis, regardless of the cutoff of 10 or 12 and in the entire cohort or the pN 0 and pN 1 groups. Based on the multivariate analysis of the entire cohort and the pN 1 group, the nodal status, the number of positive nodes and the LNR were all associated with survival.CONCLUSIONS: In addition to the nodal status, the number of positive nodes and the LNR can serve as comprehensive factors for the evaluation of nodal involvement. This approach may be more effective for predicting the survival of patients with pancreatic adenocarcinoma after pancreatectomy. | Zu-Qiang Liu Zhi-Wen Xiao Guo-Pei Luo Liang Liu Chen Liu Jin Xu Jiang Long Quan-Xing Ni Xian-Jun Yu | 2014 | Hepatobiliary & Pancreatic Diseases International2014，13，6： | 6 |
| 14 | Photocatalytic degradation of amoxicillin by carbon quantum dots modified K2Ti6O13 nanotubes:Effect of light wavelength显示文摘A novel carbon quantum dots modified potassium titanate nanotubes(CQDs/K2 Ti6 O13)composite photocatalyst was synthesized by hydrothermal treatment combined with calcination.X-ray diffraction(XRD)pattern and transmission electron microscopy(TEM)indicated formation of potassium titanate nanotubes and successful deposition of CQDs onto K2 Ti6 O13.The photocatalytic performance of CQDs/K2 Ti6 O13 composite was evaluated by degradation of amoxicillin(AMX)under the irradiation of visible light and lights with the wavelengths of 365,385,420,450,485,520,595 and 630 nm.The results showed that the photocatalytic activity of CQDs/K2 Ti6 O13 hybrid material was greatly enhanced compared with the neat K2 Ti6 O13 calcined at 300 ℃.The narrowed band gap energy(Eg)and transfer of photo-excited electron by CQDs inhibited the immediate combination of electron-hole pairs,thus promoting photocatalytic activity.Moreover,CQ,Ds/K2 Ti6 O13 exhibited a broad spectrum of photocatalytic ability and it was interesting that the photocatalytic activity decreased with the increase of the irradiation wavelength.Reactive oxygen species(ROS)quenching tests suggested the hole(h^+)and hydroxyl radical(^·OH)played the primary roles in photocatalytic degradation of AMX.Moreover,CQ.Ds/K2 Ti6 O13 showed good reusability for AMX photocatalytic degradation after five successive runs.This study proposed an available method for titanate nanomaterials modification,and the developed novel CQDs/K2 Ti6 O13hyb rid material is p ro mising fo r potential application on antibiotics removal fro m water and wastewater. | Qiankun Chen Long Chen Juanjuan Qi Yingqian Tong Yitao Lv Chaokai Xu Jinren Ni Wen Liu | 2019 | Chinese Chemical Letters2019，30，6： | 6 |
| 15 | Effect of grain refinement and crystallographic texture produced by friction stir processing on the biodegradation behavior of a Mg-Nd-Zn alloy显示文摘The application of a single pass of friction stir processing(FSP) to Mg-Nd-Zn alloy resulted in grain refinement, texture evolution and redistribution of second phases, which improved corrosion resistance.In this work, an as-rolled Mg-Nd-Zn alloy was subjected to FSP. The microstructure in the processed zone of the FS-400 rpm alloy exhibited refined grains, a more homogenous grain size distribution, less second phases, and stronger basal plane texture. The corrosion behavior assessed using immersion tests and electrochemical tests in Hank’s solution indicated that the FS-400 rpm alloy had a lower corrosion rate, which was attributed to the increase of basal plane intensity and grain refinement. The hardness was lowered slightly and the elongation was increased, which might be attributed to the redistribution of the crushed second phases. | Wen Zhang Lili Tan Dingrui Ni Junxiu Chen Ying-Chao Zhao Long Liu Cijun Shuai Ke Yang Andrej Atrens Ming-Chun Zhao | 2019 | Journal of Materials Science & Technology2019，35，5： | 6 |

| 17 | Serine metabolism orchestrates macrophage polarization by regulating the IGF1–p38 axis显示文摘Serine metabolism is reportedly involved in immune cell functions, but whether and how serine metabolism regulates macrophage polarization remain largely unknown. Here, we show that suppressing serine metabolism, either by inhibiting the activity of the key enzyme phosphoglycerate dehydrogenase in the serine biosynthesis pathway or by exogenous serine and glycine restriction, robustly enhances the polarization of interferon-γ-activated macrophages (M(IFN-γ)) but suppresses that of interleukin-4-activated macrophages (M(IL-4)) both in vitro and in vivo. Mechanistically, serine metabolism deficiency increases the expression of IGF1 by reducing the promoter abundance of S-adenosyl methionine-dependent histone H3 lysine 27 trimethylation. IGF1 then activates the p38-dependent JAK–STAT1 axis to promote M(IFN-γ) polarization and suppress STAT6-mediated M(IL-4) activation. This study reveals a new mechanism by which serine metabolism orchestrates macrophage polarization and suggests the manipulation of serine metabolism as a therapeutic strategy for macrophage-mediated immune diseases. | Xiao Shan Penghui Hu Lina Ni Long Shen Yanan Zhang Zemin Ji Yan Cui Meihua Guo Haoan Wang Liyuan Ran Kun Yang Ting Wang Lei Wang Bin Chen Zhi Yao Vingjie Wu Qiujing Yu | 2022 | Cellular & Molecular Immunology2022，19，11： | 5 |
| 18 | Integration of nanoscale light emitters:an efficient ultraviolet and blue random lasing from NaYF_4:Yb/Tm hexagonal nanocrystals显示文摘Near infrared light-controlled release of payloads from ultraviolet-sensitive(UV-sensitive) polymer hydrogels or nanocarriers is one of the most promising strategies for biotherapy. Here, we propose the concept of light activation of NaYF_4:20%Yb, 2%Tm nanocrystals(NCs). NaYF_4:20%Yb, 2%Tm NCs are synthesized by a solvothermal method. Effective upconversion luminescence from NaYF_4:20%Yb, 2%Tm NCs excited by a continuous wave(CW) 980 nm laser is obtained. The NaYF_4:20%Yb, 2%Tm NCs are then used as a laser gain medium and sandwiched between Al and quartz reflectors to form laser microcavities. UV and blue upconverted random lasing is obtained from the laser microcavities. Hence, we verify explicitly that the NaYF_4:Yb, Tm NCs support UV and blue upconversion random lasing via a 980 nm nanosecond laser excitation. Our work provides what we believe is a new concept for precision and localized cancer therapy by external light excitation. | YA-PEI PENG WEI LU PENGPENG REN YIQUN NI YUNFENG WANG LONG ZHANG YU-JIA ZENG WENFEI ZHANG SHUANGCHEN RUAN | 2018 | Photonics Research2018，6，10： | 4 |

| 20 | Ectopic expression of VRT-A2 underlies the origin of Triticum polonicum and Triticum petropavlovskyi with long outer glumes and grains显示文摘Polish wheat (Triticum polonicum) is a unique tetraploid wheat species characterized by an elongated outer glume. The genetic control of the long-glume trait by a single semi-dominant locus, P1 (from Polish wheat), was established more than 100 years ago, but the underlying causal gene and molecular nature remain elusive. Here, we report the isolation of VRT-A2, encoding an SVP-clade MADS-box transcription factor, as the P1 candidate gene. Genetic evidence suggests that in T. polonicum, a naturally occurring sequence rearrangement in the intron-1 region of VRT-A2 leads to ectopic expression of VRT-A2 in floral organs where the long-glume phenotype appears. Interestingly, we found that the intron-1 region is a key ON/OFF molecular switch for VRT-A2 expression, not only because it recruits transcriptional repressors, but also because it confers intron-mediated transcriptional enhancement. Genotypic analyses using wheat accessions indicated that the P1 locus is likely derived from a single natural mutation in tetraploid wheat, which was subsequently inherited by hexaploid T. petropavlovskyi. Taken together, our findings highlight the promoter-proximal intron variation as a molecular basis for phenotypic differentiation, and thus species formation in Triticum plants. | Jing Liu Zhaoyan Chen Zhihui Wang Zhaoheng Zhang Xiaoming Xie Zihao Wang Lingling Chai Long Song Xuejiao Cheng Man Feng Xiaobo Wang Yanhong Liu Zhaorong Hu Jiewen Xing Zhenqi Su Huiru Peng Mingming Xin Yingyin Yao Weilong Guo Qixin Sun Jie Liu Zhongfu Ni | 2021 | Molecular Plant2021，14，9： | 4 |
