| 5 | Characterization of the receptor-binding domain(RBD)of 2019 novel coronavirus:implication for development of RBD protein as a viral attachment inhibitor and vaccine显示文摘The outbreak of Coronavirus Disease 2019(COVID-19)has posed a serious threat to global public health,calling for the development of safe and effective prophylactics and therapeutics against infection of its causative agent,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),also known as 2019 novel coronavirus(2019-nCoV).The CoV spike(S)protein plays the most important roles in viral attachment,fusion and entry,and serves as a target for development of antibodies,entry inhibitors and vaccines.Here,we identified the receptor-binding domain(RBD)in SARS-CoV-2 S protein and found that the RBD protein bound strongly to human and bat angiotensin-converting enzyme 2(ACE2)receptors.SARS-CoV-2 RBD exhibited significantly higher binding affinity to ACE2 receptor than SARS-CoV RBD and could block the binding and,hence,attachment of SARS-CoV-2 RBD and SARS-CoV RBD to ACE2-expressing cells,thus inhibiting their infection to host cells.SARS-CoV RBD-specific antibodies could crossreact with SARS-CoV-2 RBD protein,and SARS-CoV RBD-induced antisera could cross-neutralize SARS-CoV-2,suggesting the potential to develop SARS-CoV RBD-based vaccines for prevention of SARS-CoV-2 and SARS-CoV infection. | Wanbo Tai Lei He Xiujuan Zhang Jing Pu Denis Voronin Shibo Jiang Yusen Zhou Lanying Du | 2020 | Cellular & Molecular Immunology2020,17,6: | 35 |
| 6 | Agricultural non-point nitrogen pollution control function of dierent vegetation types in riparian wetlands: A case study in the Yellow River wetland in China显示文摘Riparian wetland is the major transition zone of matter, energy and information transfer between aquatic and terrestrial ecosystems and has important functions of water purification and non-point pollution control. Using the field experiment method and an isotope tracing technique, the agricultural non-point nitrogen pollution control function of dierent vegetation types in riparian wetland was studied in the Kouma Section of the Yellow River. The results showed that the retention of agricultural non-point nitrogen pollution by riparian wetland soil occurs mainly in top 0-10 cm layer. The amount of nitrogen retained by surface soils associated with three types of vegetation are 0.045 mg/g for Phragmites communis Trin Linn, 0.036 mg/g for Scirpus triqueter Linn, and 0.032 mg/g for Typha angustifolia Linn, which account for 59.21%, 56.25%, and 56.14% of the total nitrogen interception, respectively. Exogenous nitrogen in 0-10 cm soil layer changes more quickly than in other layers. One month after adding K15NO3 to the tested vegetation, nitrogen content was 77.78% for P. communis Trin, 68.75% for T. angustifolia, and 8.33% for S. triqueter in the surface soil. After three months, nitrogen content was 93.33% for P. communis Trin, 72.22% for S. triqueter, and 37.50% for T. Angustifolia. There are large dierences among vegetation communities respecting to purification of agricultural non-point nitrogen pollution. The nitrogen uptake amount decreases in the sequence: new shoots of P. communis Trin (9.731 mg/g) > old P. communis Trin (4.939 mg/g) > S. triqueter (0.620 mg/g) > T. angustifolia (0.186 mg/g). Observations indicated that the presence of riparian wetlands as buers on and adjacent to stream banks could be recommended to control agricultural non-point pollution. | ZHAO Tongqian XU Huashan HE Yuxiao TAI Chao MENG Hongqi ZENG Fanfu XING Menglin | 2009 | Journal of Environmental Sciences2009,21,7: | 29 |
| 7 | Effect of sinter layer porosity distribution on flow and temperature fields in a sinter cooler显示文摘When sinters are filled into the sinter cooler from the sintering machine, it is commonly seen that, due to segregation effects, sinters of larger size usually accumulate closer to the inner wall of the sinter cooler, whereas those of smaller size are to the outer wall. This nonuniform distribution of sinters has led to uneven cooling effect throughout the cooler. This causes the sinters leaving the cooler at a large temperature difference. This undesired temperature difference leads to the deformation and even the destruction of the conveyors. The computational fluid dynamics (CFD) technique was used in the present work to investigate the heat and fluid flow phenomena within the sinter cooler corresponding to the different distribution of sinter layer porosity, which was highly dependent on the arrangement and orientation of sinters within the sinter cooler. It is confirmed that a high mass flow rate within the sinter layer causes a low temperature region and vice versa. The flow fields for vertically reducing porosity distribution and random distribution are almost identical indicating the relative insignificance of convective heat transfer mechanism. | Jik-chang Leong Kai-wun Jin Jia-shyan Shiau Tzer-ming Jeng Chang-hsien Tai | 2009 | International Journal of Minerals,Metallurgy and Materials2009,16,3: | 27 |
| 8 | Management of acquired bronchobiliary fistula:A systematic literature review of 68 cases published in 30 years显示文摘AIM:To outline the appropriate diagnostic methods and therapeutic options for acquired bronchobiliary fistula(BBF).METHODS:Literature searches were performed in Medline,EMBASE,PHMC and LWW(January 1980August 2010)using the following keywords:biliobronchial fistula,bronchobiliary fistula,bronchobiliary fistula,biliarybronchial fistula,tracheobiliary fistula,hepatobronchial fistula,bronchopleural fistula,and biliptysis.Further articles were identified through crossreferencing.RESULTS:Sixtyeight cases were collected and reviewed.BBF secondary to tumors(32.3%,22/68),including primary tumors(19.1%,13/68)and hepatic metastases(13.2%,9/68),shared the largest proportion of all cases.Biliptysis was found in all patients,and other symptoms were respiratory symptoms,such as irritating cough,fever(36/68)and jaundice(20/68).Half of the patients were treated by lessinvasive methods such as endoscopic retrograde biliary drainage.Invasive approaches like surgery were used less frequently(41.7%,28/67).The outcome was good at the end of the followup period in 28 cases(range,2 wk to 72 mo),and the recovery rate was 87.7%(57/65).CONCLUSION:The clinical diagnosis of BBF can be established by sputum analysis.Careful assessment of this condition is needed before therapeutic procedure.Invasive approaches should be considered only when noninvasive methods failed. | Guan-Qun Liao Hao Wang Guang-Yong Zhu Kai-Bin Zhu Fu-Xin Lv Sheng Tai | 2011 | World Journal of Gastroenterology2011,17,33: | 28 |
| 9 | Esophagectomy for locally advanced esophageal cancer, followed by chemoradiotherapy and adjuvant chemotherapy显示文摘AIM: To compare the efficacy and toxicity of a three-step combination therapy with post-operative radiation alone for locally advanced esophageal cancer.METHODS: Patients with T3-4 and N0-1 esophageal carcinoma from a number of institutions were non-randomly,prospectively enrolled in the study. All patients underwent single-stage curative en bloc esophagectomy. The patients were then assigned into one of two treatment groups based on treatment consisting of either post-operative concurrent chemoradiotherapy (CCRT) with weekly cisplatin 30 mg/m2 followed by systemic adjuvant chemotherapy (four monthly cycles of cisplatin 20 mg/m2 and 5-fiuorouracil 1 000 mg/m2 for five consecutive days),or, post-operative radiation alone. The radiotherapy dose was 55-60 Gy for all patients. Primary end-point of this study was to assess the per-protocol patients' improvement of overall survival benefit. Secondary end-point was designed to evaluate both the per-protocol and intent-to-treat patients' outcome of survival.RESULTS: A total of 60 patients (n = 30 per group) were enrolled in this study. The two groups were generally comparable for demographic characteristics and hematological and non-hematological toxicities. The CCRT with weekly cisplatin was well tolerated, with significantly better overall survival (30.9 mo vs 20.7 mo; 95% CI,27.5-36.4 vs15.2-26.1) and 3-year survival (70.0% vs 33.7%; P = 0.003). Low histological grade of tumor (P<0.001) was associated with favorable survival in these locally advanced patients.CONCLUSION: For locally advanced esophageal cancer,the combination of esophagectomy, post-operative CCRT with weekly cisplatin and systemic adjuvant chemotherapy is well tolerated and effective. A large-scale, prospective randomized trial of this regimen is in progress. | Hung-Chang Liu Shih-Kai Hung Cham-Jer Huang Chung-Chu Chen Ming-Jen Chen Chun-Chao Chang Cheng-Jeng Tai Chi-Yuan Tzen Li-Hua Lu Yu-Jen Chen | 2005 | World Journal of Gastroenterology2005,11,34: | 25 |
| 10 | Smashing Tissue Extraction and HPLC Determination of Active Saponins from Different Parts of Panax notoginseng显示文摘Objective To optimize the extraction technology used for extracting active saponins from the roots,fibrous roots,basal part of stems,root verrucae,fruits,flowers,stems,and leaves of Panax notoginseng based on the contents of ginsengsides Rg1,Rb1,and notoginsengside R1 as evaluation indexes.Methods Different parts of P.notoginseng were extracted by smashing tissue extraction(STE),ultrasound extraction,and reflux extraction.The contents of ginsengsides Rg1,Rb1,and notoginsengside R1 in 24 kinds of extracts were determined by HPLC-UV.Hypersil C18 column(200 mm × 4.6 mm,5 μm) and acetonitrile-warter(20:80 for 30 min→45:55 for 18 min→70:30 for 2 min→80:20 for 10 min→100:0) were used;UV detector was set at 203 nm;The flow rate was set at 1.0 mL/min.Results STE was the most efficient technology with the highest yield of active saponins among the three tested extraction technologies.Conclusion STE is a fast,effective,and economical method to extract the active saponins from different parts of P.notoginseng.It could significantly shorten the extraction time and simplify the determination of the pre-processing work on identifying P.notoginseng.Such quick and effective extraction provides a powerful tool for analyzing P.notoginseng in the future. | Sheng-ming SHI Yan-ze LIU Wen TAI Chang-qing CHEN Yu-qing ZHAO | 2012 | Chinese Herbal Medicines2012,4,4: | 24 |

| 12 | Shear-wave splitting in the crust:Regional compressive stress from polarizations of fast shear-waves显示文摘When propagating through anisotropic rocks in the crust,shear-waves split into faster and slower components with almost orthogonal polarizations.For nearly vertical propagation the polarization of fast shear-wave(PFS)is parallel to both the strike of the cracks and the direction of maximum horizontal stress,therefore it is possible to use PFS to study stress in the crust.This study discusses several examples in which PFS is applied to deduce the compressive stress in North China,Longmenshan fault zone of east edge of Tibetan plateau and Yunnan zone of southeast edge of Tibetan plateau,also discusses temporal variations of PFS orientations of 1999 Xiuyan earthquake sequences of northeastern China.The results are consistent to those of other independent traditional stress measurements.There is a bridge between crustal PFS and the crustal principal compressive stress although there are many unclear disturbance sources.This study suggests the PFS results could be used to deduce regional and in situ principal compressive stress in the crust only if there are enough seismic stations and enough data.At least,PFS is a useful choice in the zone where there are a large number of dense seismic stations. | Yuan Gao Yutao Shi Jing Wu Lingxue Tai | 2012 | Earthquake Science2012,25,1: | 20 |
| 13 | Effect of ginger Effect of ginger on gastric motility and symptoms of functional dyspepsiaon gastric motility and symptoms of functional dyspepsia显示文摘AIM:To evaluate the effects of ginger on gastric motility and emptying,abdominal symptoms,and hormones that influence motility in dyspepsia.METHODS:Eleven patients with functional dyspepsia were studied twice in a randomized double-blind manner.After an 8-h fast,the patients ingested three capsules that contained ginger(total 1.2 g) or placebo,followed after 1 h by 500 mL low-nutrient soup.Antral area,fundus area and diameter,and the frequency of antral contractions were measured using ultrasound at frequent intervals,and the gastric half-emptying time was calculated from the change in antral area.Gastrointestinal sensations and appetite were scored using visual analog questionnaires,and blood was taken for measurement of plasma glucagon-like peptide-1(GLP-1),motilin and ghrelin concentrations,at intervals throughout the study.RESULTS:Gastric emptying was more rapid after ginger than placebo [median(range) half-emptying time 12.3(8.5-17.0) min after ginger,16.1(8.3-22.6) min after placebo,P ≤ 0.05].There was a trend for more antral contractions(P = 0.06),but fundus dimensions and gastrointestinal symptoms did not differ,nor did serum concentrations of GLP-1,motilin and ghrelin.CONCLUSION:Ginger stimulated gastric emptying and antral contractions in patients with functional dyspepsia,but had no impact on gastrointestinal symptoms or gut peptides. | Ming-Luen Hu Christophan K Rayner Keng-Liang Wu Seng-Kee Chuah Wei-Chen Tai Yeh-Pin Chou Yi-Chun Chiu King-Wah Chiu Tsung-Hui Hu | 2011 | World Journal of Gastroenterology2011,17,1: | 19 |

| 15 | FoxM1 overexpression promotes epithelial-mesenchymal transition and metastasis of hepatocellular carcinoma显示文摘AIM: To investigate the expression of forkhead box protein M1(Fox M1) in the process of epithelial mesenchymal transition in hepatocellular carcinoma(HCC) and its role in metastasis.METHODS: Fox M1 and E-cadherin expression in HCC tissue microarray specimens was evaluated by immunohistochemical staining,and statistical methods were applied to analyze the correlation between FoxM 1 and epithelial-mesenchymal transition(EMT).KaplanMeier analysis of the correlation between the Fox M1 expression level and recurrence or overall survival of HCC patients was performed.The expression of FoxM 1,E-cadherin and snail homologue 1(SNAI1) in HCC cell lines was evaluated by real-time reverse transcriptionpolymerase chain reaction and Western blot.Hepatocyte growth factor(HGF) was used to induce EMT and stimulate cell migration in HCC cells.The expression of Fox M1 and SNAI1 was regulated by transfection with plasmids pc DNA3.1 and si RNAs in vitro.The occurrence of EMT was evaluated by Transwell assay,morphologic analysis and detection of the expression of EMT markers(E-cadherin and vimentin).Luciferase and chromatin immunoprecipitation assays were used to evaluate whether SNAI1 is a direct transcriptional target of FoxM 1.RESULTS: FoxM 1 expression was increased significantly in HCC compared with para-carcinoma(10.7 ± 0.9 vs 8.2 ± 0.7,P < 0.05) and normal hepatic(10.7 ± 0.9 vs 2.7 ± 0.4,P < 0.05) tissues.Overexpression of Fox M1 was correlated with HCC tumor size,tumor number,macrovascular invasion and higher TNM stage,but was negatively correlated with E-cadherin expression in microarray specimens and in cell lines.Fox M1 overexpression was correlated significantly with HCC metastasis and EMT.In vitro,we found that FoxM 1 plays a key role in HGF-induced EMT,and overexpression of Fox M1 could suppress E-cadherin expression and induce EMT changes,which were associated with increased HCC cell invasiveness.Next,we confirmed that FOXM1 directly binds to and activates the SNAI1 promoter,and we identified SNAI1 as a direct transcriptional target of FOXM1.Moreover,inhibiting the expression of SNAI1 significantly inhibited FoxM 1-mediated EMT.CONCLUSION: Fox M1 overexpression promotes EMT and metastasis of HCC,and SNAI1 plays a critical role in FoxM 1-mediated EMT. | Fan-Di Meng Ji-Chao Wei Kai Qu Zhi-Xin Wang Qi-Fei Wu Ming-Hui Tai Hao-Chen Liu Rui-Yao Zhang Chang Liu | 2015 | World Journal of Gastroenterology2015,21,1: | 17 |
| 16 | Identification of Hercynian shoshonitic intrusive rocks in central Hainan Island and its geotectonic implications显示文摘An identification has been made of some shoshonitic intrusive rocks in central Hainan Island recently. These rocks are K-rich (K2O=2.9%―5.1%, K2O/Na2O=0.95―2.12), distinctly enriched in LILE and LREE, strongly depleted in Nb, Ta, and moder- ately depleted in Sr and Ti, with (87Sr/86Sr)i = 0.70859―0.71425 and ε Nd(t) = (?2.77―?7.49). They were derived from an EMⅡ-type mantle source. The enrichment process is related to metasomatism of depleted mantle caused by a great amount of fluid-melt released from oceanic crust and terri- genous sediments at great depth (eclogite facies) during the subduction of the South China plate under the Indochina-South China Sea plate in the Carbon- iferous–Early Permian. A SHRIMP U-Pb zircon dating yields a crystallization age of 272±7 Ma for the sho- shonitic intrusions, which is coeval with the strongly peraluminous granites found in central Hainan Island. These two kinds of rocks generally possess syn-intrusion ductile deformation structures. Thus they are considered to have been generated during the early stage (syn-thrust phase) of a post-collisional event. The primary magma of shoshonitic rocks was produced at a depth > 80 km by decompression- dehydration melting of previously enriched litho- spheric mantle wedge, phlogopite-bearing garnet peridotite, which was in turn caused by the break-off of a descendent slab and upwelling of a hot as- thenosphere. The rising of melts was accompaniedby crustal contamination and crystallization fractiona- tion (AFC). Combining with other related data, it is proposed that the southwards subduction and amal- gamation of the South China plate with the Indo- China-South China Sea plate took place at ca. 287- 278 Ma, which was a part of the convergence proc- ess of the Pangea supercontinent. The suture zone was probably located along the line of Song Ma-Beibu Gulf-north margin of the Yunkai Moun- tains-Wuyi Mountains. | XIE Caifu ZHU Jinchu DING Shijiang ZHANG Yeming FU Tai'an LI Zhihong | 2006 | Chinese Science Bulletin2006,51,20: | 17 |

| 19 | Current status in the treatment options for esophageal achalasia显示文摘Recent advances in the treatment of achalasia include the use of high-resolution manometry to predict the outcome of patients and the introduction of peroral endoscopic myotomy(POEM).The first multicenter randomized,controlled,2-year follow-up study conducted by the European Achalasia Trial group indicated that laparoscopic Heller myotomy(LHM)was not superior to pneumatic dilations(PD).Publications on the long-term success of laparoscopic surgery continue to emerge.In addition,laparoscopic single-site surgery is applicable to advanced laparoscopic operations such as LHM and anterior fundoplication.The optimal treatment option is an ongoing matter of debate.In this review,we provide an update of the current progress in the treatment of esophageal achalasia.Unless new conclusive data prove otherwise,LHM is considered the most durable treatment for achalasia at the expense of increased reflux-associated complications.However,PD is the first choice for non-surgical treatment and is more costeffective.Repeated PD according to an'on-demand'strategy based on symptom recurrence can achieve long-term remission.Decision making should be based on clinical evidence that identifies a subcategory of patients who would benefit from specific treatment options.POEM has shown promise but its long-term efficacy and safety need to be assessed further. | Seng-Kee Chuah Chien-Hua Chiu Wei-Chen Tai Jyong-Hong Lee Hung-I Lu Chi-Sin Changchien Ping-Huei Tseng Keng-Liang Wu | 2013 | World Journal of Gastroenterology2013,19,33: | 15 |
