| 1 | Serrated polyps of the colon and rectum:Remove or not?显示文摘In recent years,the serrated neoplasia pathway where serrated polyps arise as a colorectal cancer has gained considerable attention as a new carcinogenic pathway.Colorectal serrated polyps are histopathologically classified into hyperplastic polyps(HPs),sessile serrated lesions,and traditional serrated adenomas;in the serrated neoplasia pathway,the latter two are considered to be premalignant.In western countries,all colorectal polyps,including serrated polyps,apart from diminutive rectosigmoid HPs are removed.However,in Asian countries,the treatment strategy for colorectal serrated polyps has remained unestablished.Therefore,in this review,we described the clinicopathological features of colorectal serrated polyps and proposed to remove HPs and sessile serrated lesions≥6 mm in size,and traditional serrated adenomas of any size. | Wataru Sano Daizen Hirata Akira Teramoto Mineo Iwatate Santa Hattori Mikio Fujita Yasushi Sano | 2020 | World Journal of Gastroenterology2020，26，19： | 12 |
| 2 | No apparent lock-in depth of the Laschamp geomagnetic excursion: Evidence from the Malan loess显示文摘The first-order chronological framework of the long-term Chinese loess/paleosol sequences was based mainly on magnetostratigraphy. However, there remain arguments on the lock-in ages of the major geomagnetic reversals. This study systematically compared the stratigraphic locations of the Laschamp excursion and Henrich events (H4 at~39 ka and H5 at~48 ka) recorded by the Luochuan loess profile in the central Chinese Loess Plateau. Results show that the Lascchamp excursion is bracketed well by these two cold events, and the corresponding estimated age is between about 41.7-43.7 ka, which is close to the widely accepted age of ~40-41 ka for the excursion.Therefore, our new results do not suggest apparent lock-in effects in the last glacial Malan loess. | ZHU Rixiang1, LIU Qingsong1,2, PAN Yongxin1, DENG Chenglong1, ZHANG Rui1 & WANG Xianfeng3 1.

| 3 | Holocene grassland vegetation, climate and human impact in central eastern Inner Mongolia显示文摘Phytolith and pollen preserved in the Taipusi Banner paleosol profile, central eastern Inner Mongolia, provide evidence of Holocene grassland vegetation, climate and human impact. The combined phytolith and pollen records reveal a major change in vegetation composition about 5000 a BP. Before 5000 a BP, the vegetation was dominated by Aneurolepidium Chinese-Stipa grandis grassland of C4 grasses. After 5000 a BP, C4 grasses rapidly retreated, indicating a shift to colder and more arid conditions. The gradual invasion of Stipa krylovii, Ag-ropyron desertorum, Ephedra, Chenopodiaceae and Caragana reveal the onset of grassland degeneration. Between 10000 and 8720 a BP, the Aneurolepidium Chinese-Stipa grandis grassland included a small proportion of Artemisia shrub and Echionopos type plants, implying a strong winter monsoon and very weak summer monsoon. From 8720 to 7000 a BP, C4 grasses were common, indicating a strengthening of the summer monsoon. Between 7000 and 5000 a BP, the Holocene thermal maximum was evident, with a significant expansion of C4 grasses and the presence of some trees (such as Pinus and Betula, and so on) in or near the study site. From 4200?000 a BP, a sandy grassland of Artemisia and Agropyron desertorum together with Aster-type taxa occurred. Precipitation amelioration took place between 3000 and 2170 a BP, with a rapid development of Echinops type plants and a small expansion of C4 grasses. From 2170 a BP to present, human activities accelerated the process of grassland degeneration. | HUANG Fei1, Kealhofer Lisa2, XIONG Shangfa3 & HUANG Fengbao1 1.

| 4 | Radiofrequency combined with immunomodulation for hepatocellular carcinoma: State of the art and innovations显示文摘Hepatocellular carcinoma(HCC)is the most common primary liver tumor and has been considered a very immunogenic tumor.The treatment with radiofrequency ablation(RFA)has been established as the standard ablative therapy for early HCC,and is currently recognized as the main ablative tool for HCC tumors<5 cm in size;however,progression and local recurrence remain the main disadvantages of this approach.To solve this clinical problem,recent efforts were concentrated on multimodal treatment,combining different strategies,including the combination of RFA and immunotherapy.This article reviewed the combination treatment of RFA with immunotherapy and found that this treatment strategy leads to an increased response of anti-tumor T cells,significantly reduces the risk of recurrence and improves survival rates compared to RFA alone.This review highlighted scientific evidence that supports the current recommendations for pre-clinical studies,and discuss the need for further research on this topic. | Adriano Carneiro da Costa Mikael Sodergren Kumar Jayant Fernando Santa Cruz Duncan Spalding Madhava Pai Nagy Habib | 2020 | World Journal of Gastroenterology2020，26，17： | 5 |
| 5 | Operative vs non-operative management of displaced proximal humeral fractures in the elderly: A systematic review and meta-analysis of randomized controlled trials显示文摘AIM: To perform a systematic review and meta-analysis comparing operative vs non-operative treatment of displaced proximal humerus fractures in elderly patients.METHODS: A systematic literature search was performed using EMBASE and MEDLINE through the OVID interface,CINAHL,the Cochrane Central Register of Controlled Trials(CENTRAL),Proquest,Web of Science,SAE digital library,and Transportation Research Board's TRID database.Searches of conference proceedings were also conducted.All available randomized controlled trials comparing operative vs non-operative management of displaced three- and four-part proximal humerus fractures in elderly patients were included.The primary outcomes measures included physical function,pain,health related quality of life,mortality,and the re-operation rate.RESULTS: Six randomized controlled trials(n = 287) were included.There was no statistically significant difference in function(MD = 1.72,95%CI:-2.90-6.34,P = 0.47),as measured by the Constant score,between the operative and the non-operative treatment groups.There was no statistically significance difference insecondary outcomes of health related quality of life(standardized MD = 0.27,95%CI:-0.05-0.59,P = 0.09),and mortality(relative risk 1.29,95%CI: 0.50-3.35,P = 0.60).Operative treatment had a statistically significant higher re-operation rate(relative risk 4.09,95%CI: 1.50-11.15,P = 0.006),and statistically significant decreased pain(MD = 1.26,95%CI: 0.02-2.49,P = 0.05).CONCLUSION: There is moderate quality evidence to suggest that there is no difference in functional outcomes between the two treatments.Further high quality randomized controlled trials are required to determine if certain subgroup populations benefit from surgical management. | Santa Rabi Nathan Evaniew Sheila A Sprague Mohit Bhandari Gerard P Slobogean | 2015 | World Journal of Orthopedics2015，6，10： | 5 |
| 6 | Jackknife and Bootstrap Tests of the Composition Vector Trees显示文摘Composition vector trees (CVTrees) are inferred from whole-genome data by an alignment-free and parameter-free method. The agreement of these trees with the corresponding taxonomy provides an objective justification of the inferred phylogeny. In this work, we show the stability and self-consistency of CVTrees by performing bootstrap and jackknife re-sampling tests adapted to this alignment-free approach. Our ultimate goal is to advocate the viewpoint that time-consuming statistical re-sampling tests can be avoided at all in using this alignment-free approach. Agreement with taxonomy should be taken as a major criterion to estimate prokaryotic phylogenetic trees. | Guanghong Zuo1,2, Zhao Xu1,3, Hongjie Yu1,4, and Bailin Hao1,5,6 1T-Life Research Center & Department of Physics, Fudan University, Shanghai 200433, China 2Shanghai Institute of Applied Physics, Chinese Acadamy of Sciences, Shanghai 201800, China 3Applied Biosystems, Inc., Beijing 100027, China 4Fudan-VARI Center for Genetic Epidemiology, Fudan University, Shanghai 200433, China 5Institute of Theoretical Physics, Chinese Acadamy of Sciences, Beijing 100190, China 6Santa Fe Institute, Santa Fe, NM 87505, USA. | 2010 | Genomics, Proteomics & Bioinformatics2010，8，4： | 5 |
| 7 | Narrow-band imaging observation of colorectal lesions using NICE classification to avoid discarding significant lesions显示文摘AIM: To assess the risk of failing to detect diminutive and small colorectal cancers with the 'resect and discard' policy.METHODS: Patients who received colonoscopy and polypectomy were recruited in the retrospective study. Probable histology of the polyps was predicted by six colonoscopists by the use of NICE classification. The incidence of diminutive and small colorectal cancersand their endoscopic features were assessed. RESULTS: In total, we found 681 cases of diminutive(1-5 mm) lesions in 402 patients and 197 cases of small(6-9 mm) lesions in 151 patients. Based on pathology of the diminutive and small polyps, 105 and 18 were non-neoplastic polyps, 557 and 154 were low-grade adenomas, 18 and 24 were high-grade adenomas or intramucosal/submucosal(SM) scanty invasive carcinomas, 1 and 1 were SM deeply invasive carcinoma, respectively. The endoscopic features of invasive cancer were classified as NICE type 3 endoscopically.CONCLUSION: The risk of failing to detect diminutive and small colorectal invasive cancer with the 'resect and discard' strategy might be avoided through the use of narrow-band imaging observation with the NICE classification scheme and magnifying endoscopy. | Santa Hattori Mineo Iwatate Wataru Sano Noriaki Hasuike Hidekazu Kosaka Taro Ikumoto Masahito Kotaka Akihiro Ichiyanagi Chikara Ebisutani Yasuko Hisano Takahiro Fujimori Yasushi Sano | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，12： | 5 |
| 8 | Prospective real-time evaluation of diagnostic performance using endocytoscopy in differentiating neoplasia from nonneoplasia for colorectal diminutive polyps(≤ 5 mm)显示文摘AIM To clarify the diagnostic performance of endocytoscopy for differentiation between neoplastic and nonneoplastic colorectal diminutive polyps.METHODS Patients who underwent endocytoscopy between October and December 2016 at Sano Hospital were prospectively recruited. When diminutive polyps(≤5 mm) were detected, the lesions were evaluated by endocytoscopy after being stained with 0.05% crystal violet and 1% methylene blue. The diminutivepolyps were classified into five categories(EC 1 a, 1 b, 2, 3 a, and 3 b). Endoscopists were asked to take a biopsy from any lesion diagnosed as EC1 b(indicator of hyperplastic polyp) or EC2(indicator of adenoma). We have assessed the diagnostic performance of endocytoscopy for EC2 and EC1 b lesions by comparison with the histopathology of the biopsy specimen. RESULTS A total of 39 patients with 63 diminutive polyps were analyzed. All polyps were evaluated by endocytoscopy. The mean polyp size was 3.3 ± 0.9 mm. Among the 63 diminutive polyps, 60 were flat and 3 were pedunculated. The mean time required for EC observation, including the time for staining with crystal violet and methylene blue, was 3.0 ± 1.9 min. Histopathologic evaluation showed that 13 polyps were hyperplastic and 50 were adenomas. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of EC2 for adenoma compared with EC1 b for hyperplastic polyp were 98.0%, 92.3%, 96.8%, 98.0% and 92.3%, respectively. There were only two cases of disagreement between the endoscopic diagnosis made by endocytoscopy and the corresponding histopathological diagnosis.CONCLUSION Endocytoscopy showed a high diagnostic performance for differentiating between neoplastic and non-neoplastic colorectal diminutive polyps, and therefore has the potential to be used for 'real-time histopathology'. | Takahiro Utsumi Yasushi Sano Mineo Iwatate Hironori Sunakawa Akira Teramoto Daizen Hirata Santa Hattori Wataru Sano Noriaki Hasuike Kazuhito Ichikawa Takahiro Fujimori | 2018 | World Journal of Gastrointestinal Oncology2018，10，4： | 4 |
| 9 | Prokaryote phylogeny meets taxonomy: An exhaustive comparison of composition vector trees with systematic bacteriology显示文摘We perform an exhaustive, taxon by taxon, comparison of the branchings in the composition vector trees (CVTrees) inferred from 432 prokaryotic genomes available on 31 December 2006, with the bacte-riologists' taxonomy-primarily the latest online Outline of the Bergey's Manual of Systematic Bacteri-ology. The CVTree phylogeny agrees very well with the Bergey's taxonomy in majority of fine branchings and overall structures. At the same time most of the differences between the trees and the Manual have been known to biologists to some extent and may hint at taxonomic revisions. Instead of demonstrating the overwhelming agreement this paper puts emphasis on the biological implications of the differences. | GAO Lei1,2, QI Ji1**, SUN JianDong2,3 & HAO BaiLin1,2,4 1 Institute of Theoretical Physics, Chinese Academy of Sciences, Beijing 100080, China 2 T-Life Research Center, Fudan University, Shanghai 200433, China 3 Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300, China 4 Santa Fe Institute, Santa Fe, NM87501, USA Center for Comparative Genomics and Bioinformatics, Penn State University, 310 Wartik Building, University Park, PA16802, USA | 2007 | Science China(Life Sciences)2007，50，5： | 4 |
| 10 | VERTICAL HEREDITY VS. HORIZONTAL GENE TRANSFER: A CHALLENGE TO BACTERIAL CLASSIFICATION显示文摘The diversity and classification of microbes has been a long-standing issue.Molecular phylogeny of the prokaryotes based on comparison of the 16S rRNA sequences of the small ribosomal subunit has led to a reasonable tree of life in the late 1970s. How-ever, the availability of more and more complete bacterial genomes has brought about complications instead of refinement of the tree. In particular, it turns out that different choice of genes may tell different history. This might be caused by possible horizontal gene transfer (HGT) among species. There is an urgent need to develop phylogenetic methods that make use of whole genome data. We describe a new approach in molecular phylogeny,namely, tree construction based on K-tuple frequency analysis of the genomic sequences.Putting aside the technicalities, we emphasize the transition from randomness to determin-ism when the string length K increases and try to comment on the challenge mentioned in the title. | HAO Bailin(Institute of Theoretical Physics, Academy of Chinese Sciences, Beijing 100080, China Senior International Fellow of the Santa Fe Institute T-Life Research Center, Fudan University,Shanghai 200433, China)QI Ji(Institute of Theoretical Physics, Beijing 100080, China) | 2003 | Journal of Systems Science & Complexity2003，16，3： | 3 |
