| 1 | Recent advances in gastric cancer early diagnosis显示文摘Gastric cancer(GC) remains an important cause of cancer death worldwide with a high mortality rate due to the fact that the majority of GC cases are diagnosed at an advanced stage when the prognosis is poor and the treatment options are limited. Unfortunately, the existing circulating biomarkers for GC diagnosis and prognosis display low sensitivity and specificity and the GC diagnosis is based only on the invasive procedures such as upper digestive endoscopy. There is a huge need for less invasive or non-invasive tests but also highly specific biomarkers in case of GC. Body fluids such as peripheral blood, urine or saliva,stomach wash/gastric juice could be a source of specific biomarkers, providing important data for screening and diagnosis in GC. This review summarized the recently discovered circulating molecules such as microRNAs, long non-coding RNAs, circular RNAs, which hold the promise to develop new strategies for early diagnosis of GC. | Laura Necula Lilia Matei Denisa Dragu Ana I Neagu Cristina Mambet Saviana Nedeianu Coralia Bleotu Carmen C Diaconu Mihaela Chivu-Economescu | 2019 | World Journal of Gastroenterology2019，25，17： | 70 |
| 2 | Breastfeeding and chronic HBV infection: Clinical and social implications显示文摘Mother-to-child transmission of hepatitis B virus (HBV) is among the most important causes of chronic HBV infection and is the commonest mode of transmission worldwide. Currently, the presence of HBsAg, HBeAg and HBV DNA in breast milk is confirmed. Several studies have reported that breastfeeding carries no additional risk that might lead to vertical transmission. Beyond some limitations, the surveys have not demonstrated any differences in HBV transmission rate regarding feeding practices in early childhood. Promotion of breastfeeding is substantial, especially for low-income individuals and regions with uncertain, unfeasible, and unsafe water supplies. Lactoferrin, minimal inflammation or activation within the infant gut during exclusive breastfeeding, and nonspecific biological molecules in the milk are identified as major factors of breast-milk defense. This review discusses preemptive antiviral therapy during pregnancy and lactation. Long-term follow up of breast-milk HBV concentrations and correlation with serum viral load; nucleos(t)ide analogue concentrations in breast milk in HBV-positive mothers in the setting of chronic HBV infection; safety of antiviral therapy during pregnancy and lactation; and the difference in viral load in the milk in exclusive or non-exclusive breastfeeding are still open questions. The paper reviews the current data and outlines the course of further investigation into this often underestimated issue. | Mihaela Petrova Victor Kamburov | 2010 | World Journal of Gastroenterology2010，16，40： | 41 |
| 3 | 为弥漫的甲状腺腺病理的评估的 ARFI elastography : 初步的结果显示文摘 AIM:To assess whether acoustic radiation force impulse(ARFI)elastography can differentiate normal from pathological thyroid parenchyma.METHODS:We evaluated 136 subjects(mean age 45.8±15.6 years,106 women and 30 men):44(32.3%) without thyroid pathology,48(35.3%)with BasedowGraves’disease(GD),37(27.2%)with chronic autoimmune thyroiditis(CAT;diagnosed by specific tests),4(2.9%)with diffuse thyroid goiter and 3(2.2%)cases with thyroid pathology induced by amiodarone.In all patients,10 elastographic measurements were made in the right thyroid lobe and 10 in the left thyroid lobe,using a 1-4.5 MHZ convex probe and a 4-9 MHz linear probe,respectively.Median values were calculated for thyroid stiffness and expressed in meters/second(m/s).RESULTS:Thyroid stiffness(TS)assessed by means of ARFI in healthy subjects(2±0.40 m/s)was significantly lower than in GD(2.67±0.53 m/s)(P<0.0001) and CAT patients(2.43±0.58 m/s)(P=0.0002),but the differences were not significant between GDvs CAT patients(P=0.053).The optimal cut-off value for the prediction of diffuse thyroid pathology was 2.36 m/s.For this cut-off value,TS had 62.5%sensitivity,79.5% specificity,87.6%predictive positive value,55.5% negative predictive value and 72.7%accuracy for the presence of diffuse thyroid gland pathology(AUROC=0.804).There were no significant differences between the TS values obtained with linear vs convex probes and when 5 vs 10 measurements were taken in each lobe(median values).CONCLUSION:ARFI seems to be a useful method for the assessment of diffuse thyroid gland pathology. | Ioan Sporea Roxana Sirli Simona Bota Mihaela Vlad Alina Popescu Ioana Zosin | 2012 | World Journal of Radiology2012，4，4： | 25 |

| 5 | Trehalose Biosynthesis in Response to Abiotic Stresses显示文摘Trehalose is a non-reducing disaccharide that is present in diverse organisms ranging from bacteria and fungi to invertebrates, in which it serves as an energy source, osmolyte or protein/membrane protectant. The occurrence of trehalose and trehalose biosynthesis pathway in plants has been discovered recently. Multiple studies have revealed regulatory roles of trehalose-6-phosphate, a precursor of trehalose, in sugar metabolism, growth and development in plants. Trehalose levels are generally quite low in plants but may alter in response to environmental stresses. Transgenic plants overexpressing microbial trehalose biosynthesis genes have been shown to contain increased levels of trehalose and display drought, salt and cold tolerance. In-silico expression profiling of all Arabidopsis trehalose-6-phosphate synthases (TPSs) and trehalose-6-phosphate phosphatases (TPPs) revealed that certain classes of TPS and TPP genes are differentially regulated in response to a variety of abiotic stresses. These studies point to the importance of trehalose biosynthesis in stress responses. | Mihaela Iordachescu Ryozo Imai | 2008 | Journal of Integrative Plant Biology2008，50，10： | 24 |
| 6 | Prognostic significance of tumor immune microenvironment and immunotherapy:Novel insights and future perspectives in gastric cancer显示文摘Despite a decrease in gastric cancer incidence, the development of novel biologic agents and combined therapeutic strategies, the prognosis of gastric cancer remains poor. Recently, the introduction of modern immunotherapy, especially using immune checkpoint inhibitors, led to an improved prognosis in many cancers. The use of immunotherapy was also associated with manageable adverse event profiles and promising results in the treatment of patients with gastric cancer, especially in heavily pretreated patients. These data have led to an accelerated approval of some checkpoint inhibitors in this setting. Understanding the complex relationship between the host immune microenvironment and tumor and the immune escape phenomenon leading to cancer occurrence and progression will subsequently lead to the identification of prognostic immune markers. Furthermore, this understanding will result in the discovery of both new mechanisms for blocking tumor immunosuppressive signals and pathways to stimulate the local immune response by targeting and modulating different subsets of immune cells. Due to the molecular heterogeneity of gastric cancers associated with differentclinico-biologic parameters, immune markers expression and prognosis, novel immunotherapy algorithms should be personalized and addressed to selected subsets of gastric tumors, which have been proven to elicit the best clinical responses. Future perspectives in the treatment of gastric cancer include tailored dual immunotherapies or a combination of immunotherapy with other targeted agents with synergistic antitumor effects. | Daniela Cornelia Lazǎr Mihaela Flavia Avram Ioan Romosan Mǎrioara Cornianu Sorina Tǎan Adrian Goldis | 2018 | World Journal of Gastroenterology2018，24，32： | 24 |

| 8 | Angiotensin-receptor blockers as therapy for mild-to-moderate hypertension-associated non-alcoholic steatohepatitis显示文摘AIM: To evaluate insulin resistance, cytolysis and nonalcoholic steatohepatitis (NASH) score (NAS) using the Kleiner and Brunt criteria in 54 patients with NASH and mild-to-moderate hypertension, treated with telmisartan vs valsartan for 20 mo. METHODS: All patients met the NCEP-ATP TM(standard dose 20 mg o.d., n = 28). Treatment had to be taken daily at the same hour with no concomitant medication or alcohol consumption allowed. Neither the patient nor the medical staff was aware of treatment group allocation. Paired liver biopsies obtained at inclusion (visit 1) and end of treatment (EOT) were assessed by a single blinded pathologist, not aware of patient or treatment group. Blood pressure, BMI, ALT, AST, HOMA-IR, plasma triglycerides (TG) and total cholesterol (TC) were evaluated at inclusion and every 4 mo until EOT (visit 6). RESULTS: At EOT we noticed a significant decrease in ALT levels vs inclusion in all patients and this decrease did not differ significantly in group T vs group V. HOMA-IR significantly decreased at EOT vs inclusion in all patients but in group T, the mean HOMA-IR decrease per month was higher than in group V. NAS significantly diminished at EOT in all patients with a higher decrease in group T vs group V. CONCLUSION: Angiotensin receptor blockers seem to be efficient in hypertension-associated NASH. Telmisartan showed a higher efficacy regarding insulin resistance and histology, perhaps because of its specific PPAR-gamma ligand effect. | Eugen Florin Georgescu Reanina Ionescu Mihaela Niculescu Laurentiu Mogoanta Liliana Vancica | 2009 | World Journal of Gastroenterology2009，15，8： | 15 |
| 9 | New therapeutic options opened by the molecular classification of gastric cancer显示文摘Gastric cancer(GC) is one of the most lethal and aggressive cancers, being the third cause of cancer related death worldwide. Even with radical gastrectomy and the latest generation of molecular chemotherapeutics, the numbers of recurrence and mortality remains high. This is due to its biological heterogeneity based on the interaction between multiple factors, from genomic to environmental factors, diet or infections with various pathogens. Therefore, understanding the molecular characteristics at a genomic level is critical to develop new treatment strategies. Recent advances in GC molecular classification provide the unique opportunity to improve GC therapy by exploiting the biomarkers and developing novel targeted therapy specific to each subtype. This article highlights the molecular characteristics of each subtype of gastric cancer that could be considered in shaping a therapeutic decision, and also presents the completed and ongoing clinical trials addressed to those targets. The implementation of the novel molecular classification system will allow a preliminary patient selection for clinical trials, a mandatory issue if it is desired to test the efficacy of a certain inhibitor to the given target. This will represent a substantial advance as well as a powerful tool for targeted therapy. Nevertheless, translating the scientific results into new personalized treatment opportunities is needed in order to improve clinical care, the survival and quality of life of patients with GC. | Mihaela Chivu-Economescu Lilia Matei Laura G Necula Denisa L Dragu Coralia Bleotu Carmen C Diaconu | 2018 | World Journal of Gastroenterology2018，24，18： | 14 |

| 12 | Contrast-enhanced ultrasonography parameters in neural network diagnosis of liver tumors显示文摘AIM:To study the role of time-intensity curve(TIC) analysis parameters in a complex system of neural networks designed to classify liver tumors.METHODS:We prospectively included 112 patients with hepatocellular carcinoma(HCC)(n = 41),hypervascular(n = 20) and hypovascular(n = 12) liver metastases,hepatic hemangiomas(n = 16) or focal fatty changes(n = 23) who underwent contrast-enhanced ultrasonography in the Research Center of Gastroenterology and Hepatology,Craiova,Romania.We recorded full length movies of all contrast uptake phases and post-processed them offline by selecting two areas of interest(one for the tumor and one for the healthy surrounding parenchyma) and consecutive TIC analysis.The difference in maximum intensities,the time to reaching them and the aspect of the late/portal phase,as quantified by the neural network and a ratio between median intensities of the central and peripheral areas were analyzed by a feed forward back propagation multi-layer neural network which was trained to classify data into five distinct classes,corresponding to each type of liver lesion.RESULTS:The neural network had 94.45% training accuracy(95% CI:89.31%-97.21%) and 87.12% testing accuracy(95% CI:86.83%-93.17%).The automatic classification process registered 93.2% sensitivity,89.7% specificity,94.42% positive predictive value and 87.57% negative predictive value.The artificial neural networks(ANN) incorrectly classified as hemangyomas three HCC cases and two hypervascular metastases,while in turn misclassifying four liver hemangyomas as HCC(one case) and hypervascular metastases(three cases).Comparatively,human interpretation of TICs showed 94.1% sensitivity,90.7% specificity,95.11% positive predictive value and 88.89% negative predictive value.The accuracy and specificity of the ANN diagnosis system was similar to that of human interpretation of the TICs(P = 0.225 and P = 0.451,respectively).Hepatocellular carcinoma cases showed contrast uptake during the arterial phase followed by wash-out in the portal and first seconds of the late phases.For the hypovascular metastases did not show significant contrast uptake during the arterial phase,which resulted in negative differences between the maximum intensities.We registered wash-out in the late phase for most of the hypervascular metastases.Liver hemangiomas had contrast uptake in the arterial phase without agent wash-out in the portallate phases.The focal fatty changes did not show any differences from surrounding liver parenchyma,resulting in similar TIC patterns and extracted parameters.CONCLUSION:Neural network analysis of contrastenhanced ultrasonography-obtained TICs seems a promising field of development for future techniques,providing fast and reliable diagnostic aid for the clinician. | Costin Teodor Streba Mihaela Ionescu Dan Ionut Gheonea Larisa Sandulescu Tudorel Ciurea Adrian Saftoiu Cristin Constantin Vere Ion Rogoveanu | 2012 | World Journal of Gastroenterology2012，18，32： | 11 |
| 13 | Optimization and design of an aircraft's morphing wing-tip demonstrator for drag reduction at low speeds, Part II- Experimental validation using Infra-Red transition measurement from Wind Tunnel tests显示文摘In the present paper, an ‘in-house' genetic algorithm was numerically and experimentally validated. The genetic algorithm was applied to an optimization problem for improving the aerodynamic performances of an aircraft wing tip through upper surface morphing. The optimization was performed for 16 flight cases expressed in terms of various combinations of speeds, angles of attack and aileron deflections. The displacements resulted from the optimization were used during the wind tunnel tests of the wing tip demonstrator for the actuators control to change the upper surface shape of the wing. The results of the optimization of the flow behavior for the airfoil morphing upper-surface problem were validated with wind tunnel experimental transition results obtained with infra-red Thermography on the wing-tip demonstrator. The validation proved that the 2D numerical optimization using the ‘in-house' genetic algorithm was an appropriate tool in improving various aspects of a wing's aerodynamic performances. | Andreea Koreanschi Oliviu Sugar Gabor Joran Acotto Guillaume Brianchon Gregoire Portier Ruxandra Mihaela Botez Mahmoud Mamou Youssef Mebarki | 2017 | Chinese Journal of Aeronautics2017，30，1： | 10 |
| 14 | Therapies targeting cancer stem cells: Current trends and future challenges显示文摘Traditional therapies against cancer, chemo- and radiotherapy, have multiple limitations that lead to treatment failure and cancer recurrence. These limitations are related to systemic and local toxicity, while treatment failure and cancer relapse are due to drug resistance and self-renewal, properties of a small population of tumor cells called cancer stem cells(CSCs). These cells are involved in cancer initiation, maintenance, metastasis and recurrence. Therefore, in order to develop efficient treatments that can induce a longlasting clinical response preventing tumor relapse it is important to develop drugs that can specifically target and eliminate CSCs. Recent identification of surface markers and understanding of molecular feature associated with CSC phenotype helped with the design of effective treatments. In this review we discuss targeting surface biomarkers, signaling pathways that regulate CSCs self-renewal and differentiation, drug-efflux pumps involved in apoptosis resistance, microenvironmental signals that sustain CSCs growth, manipulation of mi RNA expression, and induction of CSCs apoptosis and differentiation, with specific aim to hamper CSCs regeneration and cancer relapse. Some of these agents are under evaluation in preclinical and clinical studies, most of them for using in combination with traditional therapies. The combined therapy using conventional anticancer drugs with CSCs-targeting agents, may offer a promising strategy for management and eradication of different types of cancers. | Denisa L Dragu Laura G Necula Coralia Bleotu Carmen C Diaconu Mihaela Chivu-Economescu | 2015 | World Journal of Stem Cells2015，7，9： | 10 |

| 16 | Epstein-Barr virus:Silent companion or causative agent of chronic liver disease?显示文摘The Epstein-Barr virus(EBV)has an important and multifaceted role in liver pathology.As a member of the herpes virus family,EBV establishes a persistent infection in more than 90%of adults.Besides acute hepatitis during primary infection,many clinical syndromes of interest for the hepatologist are associated with EBV infection.The role of EBV in the evolution of chronic hepatitis from hepatotropic viruses is considered.Chronic EBVassociated hepatitis is suspected in immunocompetent adults with compatible serology,suggestive histology and detection of the viral genome in the liver and/or increase of specific circulating cytotoxic T-lymphocytes.EBV is the main cause of post-transplant lymphoproliferative disorders which occur in up to 30%of cases.EBV-driven lymphoproliferative diseases are also recognized in non-immunocompromised patients and liver is involved in up to a third of the cases.Directly implicated in the pathogenesis of different tumors,EBV has a disputable role in hepatocellular carcinoma carcinogenesis.Further research is required in order to establish or reject the role of EBV in human liver cancer.This paper attempts to discuss the range of EBV-associated chronic liver diseases in immunocompetent patients,from mild,self-limiting mononuclear hepatitis to liver cancer. | Mihaela Petrova Victor Kamburov | 2010 | World Journal of Gastroenterology2010，16，33： | 9 |
| 17 | Helicobacter pylori and cytokine gene variants as predictors of premalignant gastric lesions显示文摘Gastric cancer remains the third leading cause of mortality from cancer worldwide and carries a poor prognosis,due largely to late diagnosis.The importance of the interaction between Helicobacter pylori(H.pylori)infection,the main risk factor,and host-related genetic factors has been studied intensively in recent years.The genetic predisposition for non-hereditary gastric cancer is difficult to assess,as neither the real prevalence of premalignant gastric lesions in various populations nor the environmental risk factors for cancer progression are clearly defined.For non-cardiac intestinal-type cancer,identifying the factors that modulate the progression from inflammation toward cancer is crucial in order to develop preventive strategies.The role of cytokines and their gene variants has been questioned in regard to non-self-limiting H.pylori gastritis and its evolution to gastric atrophy and intestinal metaplasia;the literature now includes various and non-conclusive results on this topic.The influence of the majority of cytokine single nucleotide polymorphisms has been investigated for gastric cancer but not for preneoplastic gastric lesions.Among the investigated gene variants onlyIL10T-819C,IL-8-251,IL-18RAP917997,IL-22 rs1179251,IL1-B-511,IL1-B-3954,IL4R-398 and IL1RN were identified as predictors for premalignant gastric lesions risk.One of the most important limiting factors is the inhomogeneity of the studies(e.g.,the lack of data on concomitant H.pylori infection,methods used to assess preneoplastic lesions,and source population).Testing the modifying effect of H.pylori infection upon the relationship between cytokine gene variants and premalignant gastric lesions,or even testing the interaction between H.pylori and cytokine gene variants in multivariable models adjusted for potential covariates,could increase generalizability of results. | Anca Negovan Mihaela Iancu Emoke Fulop Claudia Banescu | 2019 | World Journal of Gastroenterology2019，25，30： | 9 |

| 19 | Permafrost warming along the Mo'he-Jiagedaqi section of the China-Russia crude oil pipeline显示文摘The permafrost along the China-Russia Crude Oil Pipeline(CRCOP) is degrading since the pipeline operation in 2011. Heat dissipated from the pipeline, climate warming and anthropogenic activities leads to permafrost warming. The processes of permafrost warming along the CRCOP were studied based on the monitoring of air and soil temperatures, and electrical resistivity tomography(ERT) surveys. Results show that:(1) the mean annual air temperature(MAAT) in permafrost regions along the CRCOP increased with a rate of 0.21°C/10a–0.40°C/10 a during the past five decades;(2) the mean annual ground temperature(MAGT, at-15 m depth) of undisturbed permafrost increased by 0.2°C and the natural permafrost table remained unchanged due to the zero-curtain effect;(3) permafrost surrounding the uninsulated pipeline right-of-way warmed significantly compared with that in a natural site. During 2012–2017, the MAGT and the artificial permafrost table, 2 m away from the pipeline centerline, increased at rates of 0.063°C/a and 1.0 m/a. The thaw bulb developed around the pipe and exhibits a faster lateral expansion;(4) 80-mm-thick insulation could reduce the heat exchange between the pipeline and underlying permafrost and then keep the permafrost and pipe stable. The MAGT and the artificial permafrost table, 4.8 m away from the center line of the pipeline, increased by 0.3°C/a and 0.43 m/a, respectively. Due to the heat disturbance caused by warm oil, the degradation of wetland, controlled burn each autumn and climate warming, the permafrost extent reduced and warmed significantly along the CRCOP route. Field observations provide basic data to clarify the interactions between CRCOP and permafrost degradation and environmental effects in the context of climate change. | WANG Fei LI Guo-yu MA Wei MAO Yun-cheng MU Yan-hu SERBAN Mihaela CAI Yong-jun | 2019 | Journal of Mountain Science2019，16，2： | 8 |
| 20 | Serum 25-hydroxyvitamin D concentration and inflammatory bowel disease characteristics in Romania显示文摘AIM:To describe the relationship between vitamin D levels and inflammatory bowel disease(IBD)characteristics in northeastern Romanian patients.METHODS:This was a prospective study of 47 consecutive IBD patients admitted to The Institute of Gastroenterology and Hepatology in Iasi,Romania between March 2011 and June 2012.The diagnosis of IBD was established based on endoscopic,histologic and radiologic findings.Demographic data,disease characteristics,ongoing treatments and biological parameters of patients(including markers of inflammation:C-reactive protein level,fibrinogen level,and erythrocyte sedimentation rate)were recorded.Serum vitamin D levels were measured and compared with age-and sexmatched healthy volunteers from the same geographic area.Vitamin D levels were defined as sufficient(>30ng/mL),insufficient(20-30 ng/mL),or severely defi-cient(<20 ng/mL).RESULTS:Thirty-three of the IBD patients included in this study had ulcerative colitis(UC)and 14 had Crohn’s disease(CD).Only 24%of the UC patients and 21%of the CD patients had sufficient vitamin D levels.The vitamin D levels were significantly lower in the CD patients with moderate to severe disease activity compared to the CD patients in remission or with mild disease activity(16±6 ng/mL vs 26±7 ng/mL;16±6 ng/mL vs 31±9 ng/mL,respectively,P<0.05).Vitamin D levels in the UC patients were not influenced by disease activity and no correlation was observed with the inflammation markers tested(C-reactive protein,fibrinogen,and erythrocyte sedimentation rate).No association was observed between vitamin D levels and smoking status or ongoing medication(5ASA,steroids,and anti-TNFα).Newly diagnosed IBD patients had lower vitamin D levels than patients with established cases,though these differences were not significant(UC:22±9 ng/mL vs 26±12 ng/mL;CD:18±6 ng/mL vs 27±11 ng/mL,respectively).Although no association was found between the season during which the visit was scheduled and vitamin D levels,the UC patients assessed during the winter tended to have lower levels than those assessed during the summer(22±9 ng/mL vs 28±13 ng/mL,respectively).CONCLUSION:Vitamin D levels are significantly reduced in IBD patients in northeastern Romania,with the lowest levels occurring in CD patients with moderate to severe disease activity. | Gabriela Dumitrescu Catalina Mihai Mihaela Dranga Cristina Cijevschi Prelipcean | 2014 | World Journal of Gastroenterology2014，20，9： | 8 |
