2Distinctive melt activity and chromite mineralization in Luobusa and Purang ophiolites, southern Tibet: constraints from trace element compositions of chromite and olivine显示文摘To investigate the factors controlling the mineralization in ophiolites we systematically compared the petrology and mineral compositions of the harzburgites/lherzolites, dunites and chromitites in the Luobusa and Purang ophiolites. Generally, the petrological features and trace element compositions of chromite and olivine in peridotite and chromitite are distinctly different between the two ophiolites.In Luobusa, boninitic melts are inferred to have interacted with the harzburgites and modified the distributions of some trace elements(e.g., Ni, Mn and V) in chromite and olivine. The subsequently formed dunites and chromitites experienced significant elemental exchange. In contrast, the Purang ophiolite contains a wider range of chromitite compositions and records diverse melt activities, such as the growth of relatively abundant secondary clinopyroxene. The metasomatic melts were enriched in Al and depleted in Si, Na and highly incompatible trace elements(e.g., Nb, Zr). Such melts resemble MORBlike melts proposed in the literature but are assumed to be more hydrous than typical MORB because of presence of hydrous minerals. The parental magmas of the Purang dunites and intermediate chromitites are inferred to be compositionally intermediate between boninitic and MORB-like melts. In addition,the more refractory nature of the Luobusa harzburgites facilitated a high Cr concentration gradient with the interacting melts, making it easier to increase Cr in the melts. Crystallization of clinopyroxene and amphibole in the Purang ophiolite accommodated significant amounts of Cr and water, respectively,and negatively affected Cr concentration and chromite crystallization. The concentration of chromite to form chromitites requires the presence of focused melt channels.Benxun Su Meifu Zhou Jiejun Jing Paul T.

4A large outbreak of acute gastroenteritis caused by the human norovirus GII.17 strain at a university in Henan Province,China显示文摘Background:Human noroviruses are a major cause of viral gastroenteritis and are the main etiological agents of acute gastroenteritis outbreaks.An increasing number of outbreaks and sporadic cases of norovirus have been reported in China in recent years.There was a large acute gastroenteritis outbreak at a university in Henan Province,China in the past five years.We want to identify the source,transmission routes of the outbreak by epidemiological investigation and laboratory testing in order to provide the effective control measures.Methods:The clinical cases were investigated,and analysed by descriptive epidemiological methods according to factors such as time,department,grade and so on.Samples were collected from clinical cases,healthy persons,the environment,water,and food at the university.These samples were tested for potential bacteria and viruses.The samples that tested positive for norovirus were selected for whole genome sequencing and the sequences were then analysed.Results:From 4 March to 3 April 2015,a total of 753 acute diarrhoea cases were reported at the university;the attack rate was 3.29%.The epidemic curve showed two peaks,with the main peak occurring between 10 and 20 March,accounting for 85.26%of reported cases.The rates of norovirus detection in samples from confirmed cases,people without symptoms,and environmental samples were 32.72%,17.39%,and 9.17%,respectively.The phylogenetic analysis showed that the norovirus belonged to the genotype GII.17.Conclusions:This is the largest and most severe outbreak caused by genotype GII.17 norovirus in recent years in China.The GII.17 viruses displayed high epidemic activity and have become a dominant strain in China since the winter of 2014,having replaced the previously dominant GII.4 Sydney 2012 strain.Xue-Yong Huang Jia Su Qian-Chao Lu Shi-Zheng Li Jia-Yong Zhao Meng-Lei Li Yi Li Xiao-Jing Shen Bai-Fan Zhang Hai-Feng Wang Yu-Jiao Mu Shu-Yu Wu Yan-Hua Du Li-Cheng Liu Wei-Jun Chen John David Klena Bian-Li Xu 2017Infectious Diseases of Poverty2017,6,1:10
5Gastric peritoneal carcinomatosis-a retrospective review显示文摘AIM To characterize patients with gastric peritoneal carcinomatosis(PC) and their typical clinical and treatment course with palliative systemic chemotherapy as the current standard of care.METHODS We performed a retrospective electronic chart review of all patients with gastric adenocarcinoma with PC diagnosed at initial metastatic presentation between January 2010 and December 2014 in a single tertiary referral centre.RESULTS We studied a total of 271 patients with a median age of 63.8 years and median follow-up duration of 5.1 mo. The majority(n = 217, 80.1%) had the peritoneum as the only site of metastasis at initial presentation. Palliative systemic chemotherapy was eventually planned for 175(64.6%) of our patients at initial presentation, of which 171 were initiated on it. Choice of first-line regime was in accordance with the National Comprehensive Cancer Network Guidelines for Gastric Cancer Treatment. Thesepatients underwent a median of one line of chemotherapy, completing a median of six cycles in total. Chemotherapy disruption due to unplanned hospitalizations occurred in 114(66.7%), while cessation of chemotherapy occurred in 157(91.8%), with 42 cessations primarily attributable to PC-related complications. Patients who had initiation of systemic chemotherapy had a significantly better median overall survival than those who did not(10.9 mo vs 1.6 mo, P < 0.001). Of patients who had initiation of systemic chemotherapy, those who experienced any disruptions to chemotherapy due to unplanned hospitalizations had a significantly worse median overall survival compared to those who did not(8.7 mo vs 14.6 mo, P < 0.001).CONCLUSION Gastric PC carries a grim prognosis with a clinical course fraught with disease-related complications which may attenuate any survival benefit which palliative systemic chemotherapy may have to offer. As such, investigational use of regional therapies is warranted and required validation in patients with isolated PC to maximize their survival outcomes in the long run.Hwee Leong Tan Claramae Shulyn Chia Grace Hwei Ching Tan Su Pin Choo David Wai-Meng Tai Clarinda Wei Ling Chua Matthew Chau Hsien Ng Khee Chee Soo Melissa Ching Ching Teo 2017World Journal of Gastrointestinal Oncology2017,9,3:6
6Investigation on reversible pump turbine flow structures and associated pressure field characteristics under different guide vane openings显示文摘The use of reversible pump turbines(RPT) within pumped storage power plants goes with prolonged periods of off-design operating conditions, which leads to the onset of operating mode-dependent instabilities. In order to decrease the gravity of RPT flow instabilities and associated damages or even completely eliminate them, a deep understanding of its onset and development mechanism is needed. In line with this, the present study seeks to numerically investigate the onset and development mechanism of RPT unsteady flow structures as well as the evolutional characteristics of associated pressure pulsations throughout the RPT complete flow passage, under off-design conditions for three GVOs namely 17, 21, and 25 mm. The study results showed that low torque operating conditions and associated vaneless space back flow structures were the trigger of flow unsteadiness onset within the RPT vaneless space, the instabilities which grew to cause the S-shape characteristics appearance. Moreover, the runner flow unsteadiness was found to decrease with the GVO increase. On the other hand, the GVO increase worsened the pressure pulsation levels within RPT flow zones, where pressure pulsations within the vaneless space and flow zones in its vicinities were found to be the most sensitive to GVO changes.BINAMA Maxime SU WenTao CAI WeiHua LI FengChen WEI XianZhu MUHIRWA Alex GONG RuZhi WEKESA David W 2019Science China(Technological Sciences)2019,62,11:5
7The expression of Spodoptera exigua P450 and UGT genes: tissue specificity and response to insecticides显示文摘Cytochrome P450 and UDP-glucosyltransferase (UGT) as phase I and phase II metabolism enzymes, respectively, play vital roles in the breakdown of endobiotics and xenobiotics. Insects can in crease the expression of detoxificatio n enzymes to cope with the stress from xenobiotics including insecticides. However, the molecular mechanisms for insecticide detoxification in Spodoptera exigua remain elusive, and the genes conferring insecticide metabolisms in this species are less well reported. In this study, 68 P450 and 32 UGT genes were identified. Phylogenetic analysis showed gene expansions in CYP3 and CYP4 clans of P450 genes and UGT33 family of this pest. P450 and UGT genes exhibited specific tissue expression patterns. Insecticide treatments in fat body cells of S. exigua revealed that the expression levels of P450 and UGT genes were significantly influenced by challenges of abamectin, lambda-cyhalothrin, chlorantraniliprole, metaflumizone and indoxacarb. Multiple genes for detoxification were affected in expression levels after insecticide exposures. The results demonstrated that lambda-cyhalothrin, chlorantraniliprole, metaflumizone and indoxacarb induced similar responses in the expression of P450 and UGT genes in fat body cells;eight P450 genes and four UGT genes were co-up-regulated significantly, and no or only a few CYP/UGT genes were down-regulated significantly by these four insecticides. However, abamectin triggered a distinct response for P450 and UGT gene expression;more P450 and UGT genes were down-regulated by abamectin than by the other four compounds. In con elusion, P450 and UGT genes from S. exigua were identified, and different responses to abamectin suggest a different mechanism for insecticide detoxification.Bo Hu Shu-Heng Zhang Miao-Miao Ren Xiang-Rui Tian Qi Wei David Kibe Mburu Jian-Ya Su 2019Insect Science2019,26,2:4
8Focal autoimmune pancreatitis and chronic sclerosing sialadenitis mimicking pancreatic cancer and neck metastasis显示文摘Type 1 autoimmune pancreatitis(AIP)or chronic sclerosing sialadenitis(Küttner’s tumour)is an uncommon disorder that has recently been confirmed as an Ig G4-related disease.Here,we describe a rare case of a53-year-old male patient who primarily presented with pancreatic body mass,left neck mass and several lumps in his lower lip mimicking pancreatic cancer(PC)and neck metastasis.The patient underwent pancreatic body mass and labial gland lumps resection as well as an ultrasound-guided biopsy of the left neck mass.He was diagnosed with Ig G4-related focal type of AIP(f-AIP)and Küttner’s tumour by immunohistochemistry.The patient responded well to corticosteroid therapy andremains healthy with no signs of recurrence at one year follow-up.The differentiation of f-AIP from PC is very important to avoid unnecessary pancreatic resection.Li Sun Qiang Zhou David R Brigstock Su Yan Ming Xiu Rong-Li Piao Yan-Hang Gao Run-Ping Gao 2014World Journal of Gastroenterology2014,20,46:3
9Consensus for prevention and management of coronavirus disease 2019 (COVID-19) for neurologists显示文摘Coronavirus disease 2019(COVID‐19)has become a pandemic disease globally.Although COVID-19 directly invades lungs,it also involves the nervous system.Therefore,patients with nervous system involvement as the presenting symptoms in the early stage of infection may easily be misdiagnosed and their treatment delayed.They become silent contagious sources or‘virus spreaders’.In order to help neurologists to better understand the occurrence,development and prognosis,we have developed this consensus of prevention and management of COVID‐19.It can also assist other healthcare providers to be familiar with and recognise COVID-19 in their evaluation of patients in the clinic and hospital environment.Huijuan Jin Candong Hong Shengcai Chen Yifan Zhou Yong Wang Ling Mao Yanan Li Quanwei He Man Li Ying Su David Wang Longde Wang Bo Hu 2020Stroke & Vascular Neurology2020,5,2:3

11CD4+Foxp3+CD25+/-Tregs characterize liver tissue specimens of patients suffering from drug-induced autoimmune hepatitis:A clinical-pathological study显示文摘Background: The diagnosis of drug-induced autoimmune hepatitis(DIAIH) and its differentiation from idiopathic autoimmune hepatitis(AIH) is challenging. This study aimed to differentiate DIAIH from AIH by comparing the biochemical changes, histological features, and frequencies of CD4^+Foxp3^+CD25^(+/-)regulatory T cells(Tregs) in liver tissues or peripheral blood lymphocytes.Methods: A total of 15 DIAIH patients and 24 AIH patients who underwent liver biopsies at initial presentation were enrolled in this study. The liver histological changes were assessed by HE staining. The phenotypic recognition and distribution of CD4^+Foxp3^+CD25^(+/-)Tregs in liver tissues were evaluated by single/double immunostains in serial sections. The CD4^+Foxp3^+CD25^(+/-)Tregs in peripheral blood were analyzed by flow cytometry.Results: The median values of ALT and AST were 404.50 U/L and 454.10 U/L in DIAIH patients and309.50 U/L and 315.00 U/L in AIH patients, respectively. More importantly, for the first time we found that patients with DIAIH had higher levels of serum ALT and AST, more severe degree of lobular inflammation,higher frequencies of zone 3 necrosis and higher number of lobular CD4^+Foxp3^+CD25^-Tregs compared with AIH(P < 0.05). Furthermore, there were positive correlations in DIAIH between the degree of lobular inflammation and either the AST/ALT level or the number of lobular CD4^+Foxp3^+CD25^-Tregs(P < 0.05).However, the frequency of peripheral blood CD4^+Foxp3^+CD25^(+/-)Tregs were not significantly different between DIAIH and AIH.Conclusions: The differences of ALT, AST and the number of lobular CD4^+Foxp3^+CD25^-Tregs between patients with DIAIH and those with AIH are clinically helpful in differentiating these two diseases in their early stage.Li-Mei Qu Shu-Hua Wang Kun Yang David R.Brigstock Li Su Run-Ping Gao 2018Hepatobiliary & Pancreatic Diseases International2018,17,2:3

15Colorectal cancer screening and surveillance in patients with inflammatory bowel disease in 2021显示文摘The detection of dysplasia in patients with inflammatory bowel disease(IBD)continues to be important given the increased risk of colorectal cancer in this population.Therefore,in 2017,we performed a review and update of the recommendations for the management and follow-up of patients with IBD based on the clinical practice guidelines of various scientific societies.The present manuscript focuses on new aspects of the detection,follow-up,and management of dysplasia according to the latest studies and recommendations.While chromoendoscopy with targeted biopsy continues to be the technique of choice for the screening and detection of dysplasia in IBD,the associated difficulties mean that it is now being compared with other techniques(virtual chromoendoscopy),which yield similar results with less technical difficulties.Furthermore,the emergence of new endoscopy techniques that are still being researched but seem promising(e.g.,confocal laser endomicroscopy and full-spectrum endoscopy),together with the development of devices that improve endoscopic visualization(e.g.,Endocuff Vision),lead us to believe that these approaches can revolutionize the screening and follow-up of dysplasia in patients with IBD.Nevertheless,further studies are warranted to define the optimal follow-up strategy in this patient population.Jose Maria Huguet Luis Ferrer-Barceló Patrícia Suárez Eva Sanchez Jose David Prieto Victor Garcia Javier Sempere 2022World Journal of Gastroenterology2022,28,5:2
