| 1 | Massive cranium from Harbin in northeastern China establishes a new Middle Pleistocene human lineage显示文摘It has recently become clear that several human lineages coexisted with Homo sapiens during the late Middle and Late Pleistocene.Here,we report an archaic human fossil that throws new light on debates concerning the diversification of the Homo genus and the origin of H.sapiens.The fossil was recovered in Harbin city in northeastern China,with a minimum uranium-series age of 146 ka.This cranium is one of the best preserved Middle Pleistocene human fossils.Its massive size,with a large cranial capacity(1,420 mL)falling in the range of modern humans,is combined with a mosaic of primitive and derived characters.It differs from all the other named Homo species by presenting a combination of features,such as long and low cranial vault,a wide and low face,large and almost square orbits,gently curved but massively developed supraorbital torus,flat and low cheekbones with a shallow canine fossa,and a shallow palate with thick alveolar bone supporting very large molars.The excellent preservation of the Harbin cranium advances our understanding of several less-complete late Middle Pleistocene fossils from China,which have been interpreted as local evolutionary intermediates between the earlier species Homo erectus and later H.sapiens.Phylogenetic analyses based on parsimony criteria and Bayesian tip-dating suggest that the Harbin cranium and some other Middle Pleistocene human fossils from China,such as those from Dali and Xiahe,form a third East Asian lineage,which is a part of the sister group of the H.sapiens lineage.Our analyses of such morphologically distinctive archaic human lineages from Asia,Europe,and Africa suggest that the diversification of the Homo genus may have had a much deeper timescale than previously presumed.Sympatric isolation of small populations combined with stochastic long-distance dispersals is the best fitting biogeographical model for interpreting the evolution of the Homo genus. | Xijun Ni Qiang Ji Wensheng Wu Qingfeng Shao Yannan Ji Chi Zhang Lei Liang Junyi Ge Zhen Guo Jinhua Li Qiang Li Rainer Grun Chris Stringer | 2021 | The Innovation2021，2，3： | 6 |

| 3 | Syndecan-2, negatively regulated by miR-20b-5p, contributes to 5-fluorouracil resistance of colorectal cancer cells via the JNK/ERK signaling pathway显示文摘5-Fluorouracil (5-FU) resistance has been long considered as an obstacle to the efficacy of chemotherapy in colorectal cancer (CRC). In this study, we demonstrated the role of miR-20b-5p-regulated syndecan-2 (SDC2) in 5-FU resistance of CRC cells. 5-FU-resistant SW480 CRC cells were established by treatment of SW480 cells with stepwise increase of 5-FU concentration. The results showed that SDC2 was expressed significantly higher in SW480/5-FU cells than in SW480/WT cells as revealed by quantitative real-time polymerase chain reaction and western blot analysis. MTT assay and BrdU assay showed that SDC2 overexpression led to increased cell survival rate, while SDC2 knockdown reversed the drug resistance of SW480/5-FU cells. Wound healing and transwell invasion assays revealed that knockdown of SDC2 inhibited the migratory and invasive ability of SW480/5-FU cells. Moreover, animal experiments indicated that si-SDC2 plays a suppressive role in tumor growth in vivo. We also confirmed that miR-20b-5p interacted with SDC2, which reversed the effect of SDC2 in SW480/5-FU cells via the c-Jun N-terminal kinase (JNK)/extracellular regulated protein kinases (ERK) signaling pathway. These findings showed that JNK/ERK signaling pathway is involved in miR-20b-5p/SDC2 axis-mediated 5-FU resistance in SW480/5-FU cells, indicating that the miR-20b-5p/SDC2 axis is a potential target for reversing 5-FU resistance in CRC. | Ruheng Hua Yan Zhang Xiyue Yan Dong Tang Xiaolong Li Qingfeng Ni Daorong Wang Jianwei Zhu | 2021 | Acta Biochimica et Biophysica Sinica2021，53，11： | 4 |
| 4 | Geochemical provenancing and direct dating of the Harbin archaic human cranium显示文摘As one of the most complete archaic human fossils,the Harbin cranium provides critical evidence for studying the diversification of the Homo genus and the origin of Homo sapiens.However,the unsystematic recovery of this cranium and a long and confused history since the discovery impede its accurate dating.Here,we carried out a series of geochemical analyses,including non-destructive X-ray fluorescence(XRF),rare earth elements(REE),and the Sr isotopes,to test the reported provenance of the Harbin cranium and get better stratigraphic constraints.The results show that the Harbin cranium has very similar XRF element distribution patterns,REE concentration patterns,and Sr isotopic compositions to those of the Middle Pleistocene-Holocene mammalian and human fossils recently recovered from the Harbin area.The sediments adhered in the nasal cavity of the Harbin cranium have a 87Sr/86Sr ratio of 0.711898,falling in the variation range measured in a core drilled near the Dongjiang Bridge,where the cranium was discovered during its reconstruction.The regional stratigraphic correlations indicate that the Harbin cranium was probably from the upper part of the Upper Huangshan Formation of the Harbin area,which has an optically stimulated luminescence dating constraint between 138 and 309 ka.U-series disequilibrium dating(n=10)directly on the cranium suggests that the cranium is older than 146 ka.The multiple lines of evidence from our experiments consistently support the theory that the Harbin cranium is from the late Middle Pleistocene of the Harbin area.Our study also shows that geochemical approaches can provide reliable evidence for locating and dating unsystematically recovered human fossils,and potentially can be applied to other human fossils without clear provenance and stratigraphy records. | Qingfeng Shao Junyi Ge Qiang Ji Jinhua Li Wensheng Wu Yannan Ji Tao Zhan Chi Zhang Qiang Li Rainer Grun Chris Stringer Xijun Ni | 2021 | The Innovation2021，2，3： | 3 |

| 7 | The Influence of Housing Prices on Urban Competitiveness:Review and Prospects显示文摘To examine the impact of housing prices on urban competitiveness, we first sort out the relevant literature on the compositions and performances of urban competitiveness. The internal compositions of urban competitiveness include factor endowments and industrial development. The external manifestations include market size, economic growth and productivity. Additionally,from the perspectives of urban economics and new economic geography, the theoretical basis of housing price’s impact on urban competitiveness is analyzed. On this basis, we analyze the mechanism and direction of housing price’s impact on urban competitiveness. The results show that most of the existing researches pay attention to the impact of housing prices on urban competitiveness through economic growth, industrial structure or production factors. However,there are differences in the specific direction of influence, and there is no research that considers the relationship of multiple influences. | NI Pengfei ZHANG Yangzi CAO Qingfeng | 2019 | Chinese Journal of Urban and Environmental Studies2019，7，3： | 0 |
| 8 | Exposure to jet lag aggravates depression-like behaviors and age-related phenotypes in rats subject to chronic corticosterone显示文摘Our previous finding demonstrated that chronic corticosterone(CORT)may be involved in mediating the pathophysiology of premature aging in rats.Frequent jet lag increases the risk for many diseases,including obesity and type 2 diabetes,and is associated with the aging processes.However,the effect of jet lag on CORT-induced depression and its association with aging phenotypes remain unclear.In this study,the rats were exposed to both CORT and jet lag treatment,and the differences were analyzed and compared to rats with single CORT treatment.Our results showed that jet lag treatment aggravated CORT-induced depression-like behavior evidenced by sucrose intake test,forced swimming test,and open field test.Additionally,this treatment aggravated the shortening of telomeres,which possibly resulted in decreased telomerase activity,and downregulated the expression of telomere-binding factor 2(TRF2)and telomerase reverse transcriptase compared to that in CORT rats,as revealed by quantitative real-time-polymerase chain reaction and western blot analysis,respectively.The shortening of telomeres may have been caused by increased oxidative stress,which was associated with the inhibition of sirtuin 3.Exposure to jet lag also aggravated the degeneration of mitochondrial functions,as shown by the decreases in the mRNA expression of COX1,ND1,and Tfam.Our findings provide physiological evidence that jet lag exposure may worsen stress-induced depression and age-related abnormalities. | Qichen Shen Junli Wu Yuehan Ni Xiaoxian Xie Chunan Yu Qingfeng Xiao Jiafeng Zhou Xia Wang Zhengwei Fu | 2019 | Acta Biochimica et Biophysica Sinica2019，51，8： | 0 |
