| 1 | Effects of Saccharomycesboulardiion fecal short-chain fatty acids and microflora in patients on long-term total enteral nutrition显示文摘AIM: To assess the effects of Sb on fecal flora and shortchain fatty acids (SCFA) in patients on long-term TEN.METHODS: Ten patients (3 females, 7 males, 59±5.5 years),on TEN for a median of 13 mo (1-125), and 15 healthy volunteers (4 females, 11 males, 32±2.0 years) received Sb (0.5 g bid PO) for 6 d. Two stool samples were taken before, on the last 2 d and 9-10 d after treatment, for SCFA measurement and for culture and bacterial identification.Values (mean±SE) were compared using sign tests and ANOVA.RESULTS: Fecal butyrate levels were lower in patients(10.1±2.9 mmol/kg) than in controls (19.2±3.9, P= 0.02).Treatment with Sb increased total fecal SCFA levels in patients (150.2±27.2 vs 107.5±18.2 mmol/kg, P = 0.02)but not in controls (129.0±28.6 vs 113.0±15.2 mmol/kg,NS). At the end of treatment with Sb, patients had higher fecal butyrate (16.0±4.4 vs 10.1 [2.9] mmol/kg, P = 0.004).Total SCFAs remained high 9 d after treatment was discontinued. Before the treatment, the anaerobe to aerobe ratio was lower in patients compared to controls (2.4±2.3 vs69.8±1.8, P = 0.003). There were no significant changes in the fecal flora of TEN patients.CONCLUSION: Sb-induced increase of fecal SCFA concentrations (especially butyrate) may explain the preventive effects of this yeast on TEN-induced diarrhea. | Stéphane M Schneider Fernand Girard-Pipau Jér(o|^)me Filippi Xavier Hébuterne Dominique Moyse Gustavo Calle Hinojosa Anne Pompei Patrick Rampal | 2005 | World Journal of Gastroenterology2005，11，39： | 26 |
| 2 | Genome survey uncovers the secrets of sex and lifestyle in caterpillar fungus显示文摘The caterpillar fungus Ophiocordyceps sinensis (best known as Cordyceps sinensis) mummifies ghost moth larvae exclusively in Tibetan Plateau alpine ecosystems. Touted as 'Himalayan Viagra', the fungus is highly prized due to its medical benefits and dwindling supplies. Attempts to culture the sexual fruiting-body have failed and the huge market demand has led to severe devastation of local ecosystems and to the fungus heading towards extinction. By genome sequencing, we establish that unlike related insect pathogens O. sinensis contains two compatible mating-type genes in its genome and is self-fertile, i.e. homothallic. However, sexual processes are only initiated under native environmental conditions. O. sinensis resembles biotrophic plant pathogens in having a genome shaped by retrotransposon-driven expansions. The resulting changes in gene content suggest that O. sinensis has a biphasic pathogenic mechanism beginning with stealth pathogenesis in early host instars. O. sinensis is the first psychrophilic fungus sequenced and is adapted to extreme cold with putative antifreeze proteins and mechanisms for increasing lipid accumulation and fatty acid unsaturation. We hypothesize that for the inbreeding O. sinensis the massive proliferation of retrotransposons provides a tradeoff between the advantages of increased genetic variation independent of sexual recombination and deletion of genes dispensable for its specialized pathogenic lifestyle. | HU Xiao ZHANG YongJie XIAO GuoHua ZHENG Peng XIA YongLiang ZHANG XingYu ST LEGER Raymond J LIU XingZhong WANG ChengShu | 2013 | Chinese Science Bulletin2013，58，23： | 26 |
| 3 | Role of human epidermal growth factor receptor 2 in gastric cancer:Biological and pharmacological aspects显示文摘Amplification of the human epidermal growth factor receptor 2(HER2)gene and overexpression of the HER2protein is found in 15%-20%of patients with gastric and gastroesophageal junction cancer.The degree of HER2 overexpression and amplification varies with the location of the carcinoma,with higher expression in the gastroesophageal and proximal parts compared to the distal parts of the stomach.Further,HER2 overexpression and amplification also seems to be related to the Lauren histological classification,with higher levels found in the intestinal phenotype compared to the diffuse and mixed types.The prognostic properties of HER2 overexpression and amplification are still under debate,but a large number of studies seem to indicate that HER2 is a negative prognostic factor.The usefulness of HER2 targeted therapy in gastric cancer was demonstrated in the ToGA trial,where HER2-positive patients with advanced gastric and gastroesophageal junction adenocarcinoma were randomized to receive5-FU/capecitabine and cisplatin,either alone or in combination with trastuzumab.A statically significant gain in overall survival was seen in patients who received the combined treatment of trastuzumab and chemotherapy.Patients with a strong overexpression of the HER2 protein(IHC3+)specifically benefited from the treatment,with a median overall survival of 17.9 mo.As a consequence of the positive results of the ToGA trial,patients with advanced gastric or gastroesophageal junction adenocarcinoma are now routinely tested for HER2.The ToGA trial must be characterized as a landmark in the treatment of gastric cancer and it has paved the way for a number of new HER2 targeted compounds such as pertuzumab,ado-trastuzumab emtansine,lapatinib,afatinib,and dacomitinib,which are currently undergoing phaseⅡandⅢclinical testing.Overall,this review will discuss the current status of HER2 in gastric and gastroesophageal junction cancer and the future direction in relation to HER2 target therapy. | Jan Tr?st J?rgensen | 2014 | World Journal of Gastroenterology2014，20，16： | 11 |
| 4 | 城市污水生物处理系统中微生物酶的活性及其分布显示文摘通过水解模式底物进行分光光度测定的方法,研究了城市污水生物处理系统中微生物酶的活性。选取亮氨酸氨基肽酶、β-葡萄糖苷酶、碱性磷酸酶和脂酶等胞外酶进行分析,结果发现4种胞外酶的平均活性在31.0~88.5μmol/(L·h),其中76.9%~94.8%的酶活性分布在活性污泥中,说明绝大部分胞外酶是与细胞相连或固定在细胞外多聚絮体基质里。混合水样和出水水样中的Doc几乎相等,而各胞外酶与DOC不存在任何显著的相关关系。增加NO3^-浓度可提高亮氨酸氨基肽酶和β-葡萄糖苷酶的活件.伯对碱件磷酸酶和脂酶却右明显的抑制作用。 | 李茵 罗翠 Chróst R J | 2007 | 环境污染与防治2007，29，5： | 8 |

| 6 | Multiple common garden experiments suggest lack of local adaptation in an invasive ornamental plant显示文摘Adaptive evolution along geographic gradients of climatic conditions is suggested to facilitate the spread of invasive plant species,leading to clinal variation among populations in the introduced range.We investigated whether adaptation to climate is also involved in the invasive spread of an ornamental shrub,Buddleja davidii,across western and central Europe.Methods We combined a common garden experiment,replicated in three climatically different central European regions,with reciprocal transplantation to quantify genetic differentiation in growth and reproductive traits of 20 invasive B.davidii populations.Additionally,we compared compensatory regrowth among populations after clipping of stems to simulate mechanical damage.Important Findings Our results do not provide evidence for clinal variation among invasive B.davidii populations:populations responded similarly to the different environments,and trait values were not correlated to climatic conditions or geographic coordinates of their home sites.Moreover,we did not detect differences in the compensatory ability of populations.We suppose that the invasive spread of B.davidii has been facilitated by phenotypic plasticity rather than by adaptation to climate and that continent-wide shuffling of cultivars due to horticultural trade may have limited local adaptation so far. | Susan K.Ebeling Jürg Stöcklin Isabell Hensen Harald Auge | 2011 | Journal of Plant Ecology2011，4，4： | 3 |
| 7 | A longitudinal study of SARS-CoV-2-infected patients reveals a high correlation between neutralizing antibodies and COVID-19 severity显示文摘Understanding the immune responses elicited by SARS-CoV-2 infection is critical in terms of protection against reinfection and,thus,for public health policy and vaccine development for COVID-19.In this study,using either live SARS-CoV-2 particles or retroviruses pseudotyped with the SARS-CoV-2 S viral surface protein(Spike),we studied the neutralizing antibody(nAb)response in serum samples from a cohort of 140 SARS-CoV-2 qPCR-confirmed infections,including patients with mild symptoms and also more severe forms,including those that required intensive care.We show that nAb titers correlated strongly with disease severity and with anti-spike IgG levels.Indeed,patients from intensive care units exhibited high nAb titers;conversely,patients with milder disease symptoms had heterogeneous nAb titers,and asymptomatic or exclusive outpatient-care patients had no or low nAbs.We found that nAb activity in SARS-CoV-2-infected patients displayed a relatively rapid decline after recovery compared to individuals infected with other coronaviruses.Moreover,we found an absence of cross-neutralization between endemic coronaviruses and SARS-CoV-2,indicating that previous infection by human coronaviruses may not generate protective nAbs against SARS-CoV-2.Finally,we found that the D614G mutation in the spike protein,which has recently been identified as the current major variant in Europe,does not allow neutralization escape.Altogether,our results contribute to our understanding of the immune correlates of SARS-CoV-2-induced disease,and rapid evaluation of the role of the humoral response in the pathogenesis of SARS-CoV-2 is warranted. | Vincent Legros Solène Denolly Manon Vogrig Bertrand Boson Eglantine Siret Josselin Rigaill Sylvie Pillet Florence Grattard Sylvie Gonzalo Paul Verhoeven Omran Allatif Philippe Berthelot Carole Pélissier Guillaume Thiery Elisabeth Botelho-Nevers Guillaume Millet Jérôme Morel Stéphane Paul Thierry Walzer François-Loïc Cosset Thomas Bourlet Bruno Pozzetto | 2021 | Cellular & Molecular Immunology2021，18，2： | 3 |
| 8 | Endoscopy-based management decreases the risk of postoperative recurrences in Crohn's disease显示文摘AIM: To investigate whether an endoscopy-based management could prevent the long-term risk of postoperative recurrence.METHODS: From the pathology department database, we retrospectively retrieved the data of all the patients operated on for Crohn's disease(CD) in our center(1986-2015). Endoscopy-based management was defined as systematic postoperative colonoscopy(median time after surgery = 9.5 mo) in patients with no clinical postoperative recurrence at the time of endoscopy. RESULTS: From 205 patients who underwent surgery, 161 patients(follow-up > 6 mo) were included. Endoscopic postoperative recurrence occurred in 67.6%, 79.7%, and 95.5% of the patients, respectively 5, 10 and 20 years after surgery. The rate of clinical postoperative recurrence was 61.4%, 75.9%, and 92.5% at 5, 10 and 20 years, respectively. The rate of surgical postoperative recurrence was 19.0%, 38.9% and 64.7%, respectively, 5, 10 and 20 years after surgery. In multivariate analysis, previous intestinal resection, prior exposure to anti-TNF therapy before surgery, and fistulizing phenotype(B3) were postoperative risk factors. Previous perianal abscess/fistula(other perianal lesions excluded), were predictive of only symptomatic recurrence. In multivariate analysis, an endoscopy-based management(n = 49/161) prevented clinical(HR = 0.4, 95%CI: 0.25-0.66, P < 0.001) and surgical postoperative recurrence(HR = 0.30, 95%CI: 0.13-0.70, P = 0.006).CONCLUSION: Endoscopy-based management should be recommended in all CD patients within the first year after surgery as it highly decreases the long-term risk of clinical recurrence and reoperation. | Anne-Laure Boucher Bruno Pereira Stéphanie Decousus Marion Goutte Felix Goutorbe Anne Dubois Johan Gagniere Corinne Borderon Juliette Joubert Denis Pezet Michel Dapoigny Pierre J Déchelotte Gilles Bommelaer Anthony Buisson | 2016 | World Journal of Gastroenterology2016，22，21： | 3 |
| 9 | Pollinator attraction in Cornus capitata (Cornaceae): the relative role of visual and olfactory cues显示文摘Aims it is generally accepted that visual displays and floral scent play important roles in communication between flowering plants and their pollinators.However,the relative role of visual and olfactory cues in pollinator attraction is largely unknown.in this study,we determined the roles of both types of cue in attracting pollinators to Cornus capitata,a medium sized tree with each capitulum sur-rounded by four large,white,petaloid bracts.Methods Pollinator observations and pollination experiments were con-ducted in a natural population;the inflorescences’visual and olfactory signals were characterized by spectral and chemical analyses;the responses of pollinators to visual and olfactory cues were tested using dual-choice behavioural bioassays;the relative roles of visual and olfactory cues in pollinator attrac-tion were tested by comparing the responses of pollinators to inflorescences subjected to three experimental treatments(intact,all bracts removed,and capitulum removed)within the natural population.Important Findings For fruit set,C.capitata is entirely dependent on pollinators,with a bee,Anthophora sp.,being the main pollinator.bracts present high colour distance and green contrast against the leaves.Twelve volatile compounds in the floral scent were detected,most of which have previously been reported to be attractive to a broad spectrum of bee species.behavioural bioassays showed that both,visual cues alone and olfactory cues alone,are attractive to pollinating bees.However,vis-ual cues alone attracted significantly more approaches than olfactory cues alone,while olfactory cues alone elicited a significantly higher landing percentage than visual cues alone.The finding suggests that,in the C.capitata-Anthophora sp.interaction,visual cues are mainly used for location from long distances,while olfactory cues mainly aid landing from short distances.our results indicate that different modalities of floral cues should be considered together to understand fully the communication between flowering plant and pollinators. | Bo Song Yang Niu Jürg Stöcklin Gao Chen De-Li Peng Yong-Qian Gao Hang Sun | 2015 | Journal of Plant Ecology2015，8，2： | 3 |
