| 2 | Helicobacter pylori infection: Beyond gastric manifestations显示文摘Helicobacter pylori(H.pylori)is a bacterium that infects more than a half of world’s population.Although it is mainly related to the development of gastroduodenal diseases,several studies have shown that such infection may also influence the development and severity of various extragastric diseases.According to the current evidence,whereas this bacterium is a risk factor for some of these manifestations,it might play a protective role in other pathological conditions.In that context,when considered the gastrointestinal tract,H.pylori positivity have been related to Inflammatory Bowel Disease,Gastroesophageal Reflux Disease,Non-Alcoholic Fatty Liver Disease,Hepatic Carcinoma,Cholelithiasis,and Cholecystitis.Moreover,lower serum levels of iron and vitamin B12 have been found in patients with H.pylori infection,leading to the emergence of anemias in a portion of them.With regards to neurological manifestations,a growing number of studies have associated that bacterium with multiple sclerosis,Alzheimer’s disease,Parkinson’s disease,and Guillain-Barrésyndrome.Interestingly,the risk of developing cardiovascular disorders,such as atherosclerosis,is also influenced by the infection.Besides that,the H.pylori-associated inflammation may also lead to increased insulin resistance,leading to a higher risk of diabetes mellitus among infected individuals.Finally,the occurrence of dermatological and ophthalmic disorders have also been related to that microorganism.In this sense,this minireview aims to gather the main studies associating H.pylori infection with extragastric conditions,and also to explore the main mechanisms that may explain the role of H.pylori in those diseases. | Maria Luisa Cordeiro Santos Breno Bittencourt de Brito Filipe Antonio França da Silva Mariana Miranda Sampaio Hanna Santos Marques Natalia Oliveira e Silva Dulciene Maria de Magalhaes Queiroz Fabricio Freire de Melo | 2020 | World Journal of Gastroenterology2020，26，28： | 34 |
| 3 | Promotion of spinosad biosynthesis by chromosomal integration of the Vitreoscilla hemoglobin gene in Saccharopolyspora spinosa显示文摘To promote spinosad biosynthesis by improving the limited oxygen supply during high-density fermentation of Saccharopolyspora spinosa, the open reading frame of the Vitreoscilla hemoglobin gene was placed under the control of the promoter for the erythromycin resistance gene by splicing using overlapping extension PCR. This was cloned into the integrating vector pSET152, yielding the Vitreoscilla hemoglobin gene expression plasmid pSET152EVHB. This was then introduced into S. spinosa SP06081 by conjugal transfer, and integrated into the chromosome by site-specific recombination at the integration site ΦC31 on pSET152EVHB. The resultant conjugant, S. spinosa S078-1101, was genetically stable. The integration was further confirmed by PCR and Southern blotting analysis. A carbon monoxide differential spectrum assay showed that active Vitreoscilla hemoglobin was successfully expressed in S. spinosa S078-1101. Fermentation results revealed that expression of the Vitreoscilla hemoglobin gene significantly promoted spinosad biosynthesis under normal oxygen and moderately oxygen-limiting conditions (P<0.01). These findings demonstrate that integrating expression of the Vitreoscilla hemoglobin gene improves oxygen uptake and is an effective means for the genetic improvement of S. spinosa fermentation. | LUO YuShuang KOU XiaoXiao DING XueZhi HU ShengBiao TANG Ying LI WenPing HUANG Fan YANG Qi CHEN HanNa XIA LiQiu | 2012 | Science China(Life Sciences)2012，55，2： | 14 |
| 4 | Porcine Coronaviruses: Overview of the State of the Art显示文摘Like RNA viruses in general,coronaviruses(CoV)exhibit high mutation rates which,in combination with their strong tendency to recombine,enable them to overcome the host species barrier and adapt to new hosts.It is currently known that six CoV are able to infect pigs.Four of them belong to the genus Alphacoronavirus[transmissible gastroenteritis coronavirus(TEGV),porcine respiratory coronavirus(PRCV),porcine epidemic diarrhea virus(PEDV),swine acute diarrhea syndrome coronavirus(SADS-CoV)],one of them to the genus Betacoronavirus[porcine hemagglutinating encephalomyelitis virus(PHEV)]and the last one to the genus Deltacoronavirus(PDCoV).PHEV was one of the first identified swine CoV and is still widespread,causing subclinical infections in pigs in several countries.PRCV,a spike deletion mutant of TGEV associated with respiratory tract infection,appeared in the 1980 s.PRCV is considered nonpathogenic since its infection course is mild or subclinical.Since its appearance,pig populations have become immune to both PRCV and TGEV,leading to a significant reduction in the clinical and economic importance of TGEV.TGEV,PEDV and PDCoV are enteropathogenic CoV and cause clinically indistinguishable acute gastroenteritis in all age groups of pigs.PDCoV and SADS-CoV have emerged in 2014(US)and in 2017(China),respectively.Rapid diagnosis is crucial for controlling CoV infections and preventing them from spreading.Since vaccines are available only for some porcine CoV,prevention should focus mainly on a high level of biosecurity.In view of the diversity of CoV and the potential risk factors associated with zoonotic emergence,updating the knowledge concerning this area is essential. | Hanna Turlewicz-Podbielska Małgorzata Pomorska-Mo´l | 2021 | Virologica Sinica2021，36，5： | 12 |
| 5 | Implications of preoperative hypoalbuminemia in colorectal surgery显示文摘Serum albumin has traditionally been used as a quantitative measure of a patient's nutritional status because of its availability and low cost. While malnutrition has a clear definition within both the American and European Societies for Parenteral and Enteral Nutrition clinical guidelines, individual surgeons often determine nutritional status anecdotally. Preoperative albumin level has been shown to be the best predictor of mortality after colorectal cancer surgery. Specifically in colorectal surgical patients, hypoalbuminemia significantly increases the length of hospital stay, rates of surgical site infections, enterocutaneous fistula risk, and deep vein thrombosis formation. The delay of surgical procedures to allow for preoperative correction of albumin levels in hypoalbuminemic patients has been shown to improve the morbidity and mortality in patients with severe nutritional risk. The importance of preoperative albumin levels and the patient's chronic inflammatory state on the postoperative morbidity and mortality has led to the development of a variety of surgical scoring systems to predict outcomes efficiently. This review attempts to provide a systematic overview of albumin and its role and implications in colorectal surgery. | Adam Truong Mark H Hanna Zhobin Moghadamyeghaneh Michael J Stamos | 2016 | World Journal of Gastrointestinal Surgery2016，8，5： | 9 |

| 7 | Use of three-dimensional printing in preoperative planning in orthopaedic trauma surgery: A systematic review and meta-analysis显示文摘BACKGROUND With the increasing complexity of surgical interventions performed in orthopaedic trauma surgery and the improving technologies used in threedimensional(3D)printing,there has been an increased interest in the concept.It has been shown that 3D models allow surgeons to better visualise anatomy,aid in planning and performing complex surgery.It is however not clear how best to utilise the technique and whether this results in better outcomes.AIM To evaluate the effect of 3D printing used in pre-operative planning in orthopaedic trauma surgery on clinical outcomes.METHODS We performed a comprehensive systematic review of the literature and a metaanalysis.Medline,Ovid and Embase were searched from inception to February 8,2018.Randomised controlled trials,case-control studies,cohort studies and case series of five patients or more were included across any area of orthopaedic trauma.The primary outcomes were operation time,intra-operative blood loss and fluoroscopy used.RESULTS Seventeen studies(922 patients)met our inclusion criteria and were reviewed.The use of 3D printing across all specialties in orthopaedic trauma surgery demonstrated an overall reduction in operation time of 19.85%[95%confidence intervals(CI):(-22.99,-16.71)],intra-operative blood loss of 25.73%[95%CI:(-31.07,-20.40)],and number of times fluoroscopy was used by 23.80%[95%CI:(-38.49,-9.10)].CONCLUSION Our results suggest that the use of 3D printing in pre-operative planning in orthopaedic trauma reduces operative time,intraoperative blood loss and the number of times fluoroscopy is used. | Catrin Morgan Chetan Khatri Sammy A Hanna Hutan Ashrafian Khaled M Sarraf | 2020 | World Journal of Orthopedics2020，11，1： | 7 |
| 8 | Optimum chemotherapy in the management of metastatic pancreatic cancer显示文摘Pancreatic cancer is one of the most devastating solid tumors,and it remains one of the most difficult to treat.The treatment of metastatic pancreatic cancer(MPC)is systemic,based on chemotherapy or best supportive care,depending on the performance status of the patient.Two chemotherapeutical regimens have produced substantial benefits in the treatment of MPC:gemcitabine in 1997;and FOLFIRIONOX in 2011.FOLFIRINOX improved the natural history of MPC,with overall survival(OS)of 11.1 mo.Nab-paclitaxel associated with gemcitabine is a newly approved regimen for MPC,with a median OS of 8.6 mo.Despite multiple trials,this targeted therapy was not efficient in the treatment of MPC.Many new molecules targeting the proliferation and survival pathways,immune response,oncofetal signaling and the epigenetic changes are currently undergoing phaseⅠandⅡtrials for the treatment of MPC,with many promising results. | Marwan Ghosn Hampig Raphael Kourie Fadi El Karak Colette Hanna Joelle Antoun Dolly Nasr | 2014 | World Journal of Gastroenterology2014，20，9： | 7 |
| 9 | Modulators affecting the immune dialogue between human immune and colon cancer cells显示文摘The link between chronic inflammation and colorectal cancer has been well established. The events proceeding along tumorigenesis are complicated and involve cells activated at the cancer microenvironment, tumor infiltrating polymorphonuclears, immune cells including lymphocyte subtypes and peripheral blood mononuclear cells(PBMC), as well as tumor-associated macrophages. The immune cells generate inflammatory cytokines, several of them playing a crucial role in tumorigenesis. Additional factors, such as gene expression regulated by cytokines, assembling of tumor growth- and transforming factors, accelerated angiogenesis, delayed apoptosis, contribute all to initiation, development and migration of tumor cells. Oxygen radical species originating from the inflammatory area promote cell mutation and cancer proliferation. Tumor cells may over-express pro-inflammatory mediators that in turn activate immune cells for inflammatory cytokines production. Consequently, an immune dialogue emerges between immune and cancer cells orchestrated through a number of activated molecular pathways. Cytokines, encompassing migration inhibitory factor, transforming growth factor beta 1, tumor necrosisfactor-α, Interleukin(IL)-6, IL-10, IL-12, IL-17, IL-23 have been reported to be involved in human cancer development. Some cytokines, namely IL-5, IL-6, IL-10, IL-22 and growth factors promote tumor development and metastasis, and inhibit apoptosis via activation of signal transducer activator transcription-3 transcription factor. Colon cancer environment comprises mesenchymal, endothelial and immune cells. Assessment of the interaction between components in the tumor environment and malignant cells requires a reconsideration of a few topics elucidating the role of chronic inflammation in carcinogenesis, the function of the immune cells expressed by inflammatory cytokine production, the immunomodulation of cancer cells and the existence of a cross-talk between immune and malignant cells leading to a balance in cytokine production. It is conceivable that the prevalence of anti-inflammatory cytokine production by PBMC in the affected colonic mucosa will contribute to the delay, or even to halt down malignant expansion. Targeting the interplay between immune and cancer cells by mediators capable to alter cytokine secretion toward increased anti-inflammatory cytokine release by PBMC and tumor associated macrophages, may serve as an additional strategy for treatment of malignant diseases. This review will focus on the inflammatory events preceding tumorigenesis in general, and on a number of modulators capable to affect colon cancer cell-induced production of inflammatory cytokines by PBMC through alteration of the immune crosstalk between PBMC and cancer cells. | Meir Djaldetti Hanna Bessler | 2014 | World Journal of Gastrointestinal Oncology2014，6，5： | 7 |
| 10 | Incipient sediment motion based on turbulent fluctuations显示文摘The current study modifies the representation of the Shields parameter using turbulent strength,i.e.the root-mean-square(rms) fluid velocity.Experiments were done under a steady,uniform flow using eight sediment sizes with particle Reynolds numbers(Rep) ranging between 1.0(fine sediment) and 183.4(coarse sediment).Utilising the peak rms horizontal(u) values,the critical Shields parameter,θ_c,was calculated and a trend similar to the well-established Shields curve was developed.The analysis was extended to the Shields curve obtained based on the critical shear velocity,Reynolds shear stress,and data extracted fro m the oscillating grid-turbulence experiments.Results show that turbulent fluctuations are crucial for the incipient sediment motion and are essentially better predictors than the commonly used critical shear velocity.A quadrant analysis to identify the role of turbulent bursting events in incipient sediment motion also was done where sweeps and ejections are dominant for finer and coarser sediment sizes,respectively. | Wan Hanna Melini Wan Mohtar Ji Wang Lee Najwa Izzaty Mohammad Azha Nian-Sheng Cheng | 2020 | International Journal of Sediment Research2020，35，2： | 7 |
| 11 | Myofibroblastic cell activation and neovascularization predict native liver survival and development of esophageal varices in biliary atresia显示文摘AIM:To study the relation between collagen 1,α-smooth muscle actin(α-SMA)and CD34 expression and the most essential portoenterostomy(PE)outcomes.METHODS:Liver specimens were obtained at PE from33 biliary atresia(BA)patients for immunohistochemical analysis of collagen 1,α-SMA and CD34.Liver biopsies from 35 organ donors were used as controls.Expression patterns were related to clinical data including age at PE,serum total and conjugated bilirubin concentration at the time of PE and during follow-up,incidence of esophageal varices in follow-up upper gastrointestinal endoscopies,and native liver survival as well as to detailed histopathological findings.RESULTS:Collagen 1(16.4%vs 4.5%,P<0.0001),α-SMA(17.9%vs 4.6%,P<0.0001)and CD34(4.9%vs 3.8%,P=0.017)were markedly overexpressed in BA patients compared with controls.Patients who underwent liver transplantation by age of two years had significantly higher expression of collagen 1(18.6%vs 13.7%,P=0.024),α-SMA(20.4%vs 15.4%,P=0.009)and CD34(5.9%vs 4.0%,P=0.029)at PE compared with native liver survivors.CD34-positive microvessels were identified in the centrizonal region close to central vein in every BA patient.In majority of BA cases(56%)neovascularization was frequent as CD34-positive microvessels were observed in over half of the hepatic lobules.In controls,the CD34-positive microvessels were rare as they were completely absent in 40%and were found in less than 5%of the hepatic lobules in the rest.The difference between BA patients and controls was significant(P<0.0001).Patients who developed esophageal varices by two years had significantly higher expression of CD34 at PE compared with patients without varices(5.6%vs 4.0%,P=0.019).Expression ofα-SMA(r=0.758,P<0.0001)and collagen 1(r=0.474,P=0.016),and the amount of CD34-positive microvessels(r=0.356,P=0.047)were related to patient age at PE.CONCLUSION:Hepatic myofibroblastic cell activation,fibrogenesis and neovascularization are enhanced in BA,progress with increasing PE age and relate to native liver survival and development of esophageal varices. | Janne S Suominen Hanna Lampela Pivi Heikkil Jouko Lohi Hannu Jalanko Mikko P Pakarinen | 2014 | World Journal of Gastroenterology2014，20，12： | 6 |
| 12 | Relationship between Th17 immune response and cancer显示文摘Cancer is the second leading cause of death worldwide and epidemiological projections predict growing cancer mortality rates in the next decades.Cancer has a close relationship with the immune system and,although Th17 cells are known to play roles in the immune response against microorganisms and in autoimmunity,studies have emphasized their roles in cancer pathogenesis.The Th17 immune response profile is involved in several types of cancer including urogenital,respiratory,gastrointestinal,and skin cancers.This type of immune response exerts pro and antitumor functions through several mechanisms,depending on the context of each tumor,including the protumor angiogenesis and exhaustion of T cells and the antitumor recruitment of T cells and neutrophils to the tumor microenvironment.Among other factors,the paradoxical behavior of Th17 cells in this setting has been attributed to its plasticity potential,which makes possible their conversion into other types of T cells such as Th17/Treg and Th17/Th1 cells.Interleukin(IL)-17 stands out among Th17-related cytokines since it modulates pathways and interacts with other cell profiles in the tumor microenvironment,which allow Th17 cells to prevail in tumors.Moreover,the IL-17 is able to mediate pro and antitumor processes that influence the development and progression of various cancers,being associated with variable clinical outcomes.The understanding of the relationship between the Th17 immune response and cancer as well as the singularities of carcinogenic processes in each type of tumor is crucial for the identification of new therapeutic targets. | Hanna Santos Marques Breno Bittencourt de Brito Filipe Antônio França da Silva Maria Luísa Cordeiro Santos Júlio César Braga de Souza Thiago Macêdo Lopes Correia Luana Weber Lopes Nayara Silva de Macêdo Neres Rafael Santos Dantas Miranda Dórea Anna Carolina Saúde Dantas Lorena Lôbo Brito Morbeck Iasmin Souza Lima Amanda Alves de Almeida Maiara Raulina de Jesus Dias Fabrício Freire de Melo | 2021 | World Journal of Clinical Oncology2021，12，10： | 5 |

| 14 | Microstructure and texture evolution of AZ31 Mg alloy after uniaxial compression and annealing显示文摘The effect of initial texture on the microstructure and texture evolution of as extruded AZ31 alloy after hot uniaxial compression at 430°C and subsequent annealing at 450°C for 72h has been investigated using electron backscatter diffraction.Samples were machined from the extruded block in such orientations that the compression axis,CD,was parallel(CD0ED)or perpendicular(CD90ED)to the initial extrusion direction,ED,respectively.Results show that the deformation microstructure for both samples was characterized by equiaxed grains that resulted from dynamic recrystallization.Annealing at 450°C for 72 h led to the increase of grains size to 28 and 25μm for CD0ED and CD90ED samples,respectively.A random deformation texture was developed in CD0ED sample while the deformation of CD90ED developed typical(0002)basal texture.The deformation textures of both samples were retained after subsequent annealing at 450°C for 72 h.The flow behavior was affected by the initial texture.The CD0ED sample showed the highest work hardening.These evolutions were explained in term of the activation and suppression of basal,non-basal slip and mechanical twinning.©2018 Published by Elsevier B.V.on behalf of Chongqing University.This is an open access article under the CC BY-NC-ND license. | Fadi Abouhilou Abdelkader Hanna Hiba Azzeddine Djamel Bradai | 2019 | Journal of Magnesium and Alloys2019，7，1： | 5 |

| 16 | Sodium alendronate loaded poly(L-lactideco-glycolide)microparticles immobilized on ceramic scaffolds for local treatment of bone defects显示文摘Bone tissue regeneration in critical-size defects is possible after implantation of a 3D scaffold and can be additionally enhanced once the scaffold is enriched with drugs or other factors supporting bone remodelling and healing.Sodium alendronate(Aln),a widely used anti-osteoporosis drug,exhibits strong inhibitory effect on bone resorption performed by osteoclasts.Thus,we propose a new approach for the treatment of bone defects in craniofacial region combining biocompatible titanium dioxide scaffolds and poly(L-lactide-co-glycolide)microparticles(MPs)loaded with Aln.The MPs were effectively attached to the surface of the scaffolds’pore walls by human recombinant collagen.Drug release from the scaffolds was characterized by initial burst(2466% of the drug released within first 24 h)followed by a sustained release phase(on average 5 mg of Aln released per day from Day 3 to Day 18).In vitro tests evidenced that Aln at concentrations of 5 and 2.5 mg/ml was not cytotoxic for MG-63 osteoblast-like cells(viability between 8166% and 9863% of control),but it prevented RANKL-induced formation of osteoclast-like cells from macrophages derived from peripheral blood mononuclear cells,as shown by reduced fusion capability and decreased tartrateresistant acid phosphatase 5b activity(5665% reduction in comparison to control after 8 days of culture).Results show that it is feasible to design the scaffolds providing required doses of Aln inhibiting osteoclastogenesis,reducing osteoclast activity,but not affecting osteoblast functions,which may be beneficial in the treatment of critical-size bone tissue defects. | Lucja Rumian Cornelia Wolf-Brandstetter Sina Roβler Katarzyna Reczynska Hanna Tiainen Havard J.Haugen Dieter Scharnweber Elzbieta Pamula | 2020 | Regenerative Biomaterials2020，7，3： | 5 |
| 17 | Role of cyclooxygenase-2 gene polymorphisms in pancreatic carcinogenesis显示文摘AIM:To evaluate the clinical significance of-765G/C and-1195G/A cyclooxygenase-2 (COX-2) gene polymorphisms in patients with pancreatic cancer (PC).METHODS:The study included 201 patients:85 with PC and 116 healthy controls.-765G/C and-1195G/A COX-2 gene polymorphisms were studied in DNA isolated from blood samples.The associations of the analyzed genotypes and clinical data at diagnosis were evaluated.RESULTS:We found an increased frequency of the homozygous-1195AA COX-2 genotype in patients with PC (53.7%) compared with the control group (21%) (P < 0.01).In contrast,the distribution of genotypeand allele frequencies of the-765G/C COX-2 polymorphism in the PC patients were not different from those in control groups.A correlation between presence of homozygous-1195AA COX-2 genotype and tumor size > 3 cm was observed (P < 0.05).Analyzed polymorphisms were unrelated to the patients' sex and age,nor to the presence of regional or distant metastases.CONCLUSION:These preliminary results indicate that the-1195G/A COX-2 polymorphism may play an important role in PC prognosis and carcinogenesis. | Renata Talar-Wojnarowska Anita Gasiorowska Marek Olakowski Pawel Lampe Beata Smolarz Hanna Romanowicz-Makowska Ewa Malecka-Panas | 2011 | World Journal of Gastroenterology2011，17，36： | 4 |

| 19 | Chronic myeloid leukemia-from the Philadelphia chromosome to specific target drugs:A literature review显示文摘Chronic myeloid leukemia(CML)is a myeloproliferative neoplasm and was the first neoplastic disease associated with a well-defined genotypic anomaly―the presence of the Philadelphia chromosome.The advances in cytogenetic and molecular assays are of great importance to the diagnosis,prognosis,treatment,and monitoring of CML.The discovery of the breakpoint cluster region(BCR)-Abelson murine leukemia(ABL)1 fusion oncogene has revolutionized the treatment of CML patients by allowing the development of targeted drugs that inhibit the tyrosine kinase activity of the BCR-ABL oncoprotein.Tyrosine kinase inhibitors(known as TKIs)are the standard therapy for CML and greatly increase the survival rates,despite adverse effects and the odds of residual disease after discontinuation of treatment.As therapeutic alternatives,the subsequent TKIs lead to faster and deeper molecular remissions;however,with the emergence of resistance to these drugs,immunotherapy appears as an alternative,which may have a cure potential in these patients.Against this background,this article aims at providing an overview on CML clinical management and a summary on the main targeted drugs available in that context. | Mariana Miranda Sampaio Maria Luísa Cordeiro Santos Hanna Santos Marques Vinícius Lima de Souza Gonçalves Glauber Rocha Lima Araújo Luana Weber Lopes Jonathan Santos Apolonio Camilo Santana Silva Luana Kauany de SáSantos Beatriz Rocha Cuzzuol Quézia Estéfani Silva Guimarães Mariana Novaes Santos Breno Bittencourt de Brito Filipe Antônio França da Silva Márcio Vasconcelos Oliveira Cláudio Lima Souza Fabrício Freire de Melo | 2021 | World Journal of Clinical Oncology2021，12，2： | 3 |
