1Anti-inflammatory properties of the short-chain fatty acids acetate and propionate:A study with relevance to inflammatory bowel disease显示文摘AIM: To compare the anti-inflammatory properties of butyrate with two other SCFAs,namely acetate and propionate,which have less well-documented effects on inflammation. METHODS: The effect of SCFAs on cytokine release from human neutrophils was studied with ELISA. SCFA-dependent modulation of NF-κB reporter activity was assessed in the human colon adenocarcinoma cell line,Colo320DM. Finally,the effect of SCFAs on gene expression and cytokine release,measured with RT-PCR and ELISA,respectively,was studied in mouse colon organ cultures established from colitic mice. RESULTS: Acetate,propionate and butyrate at 30 mmol/L decreased LPS-stimulated TNFα release from neutrophils,without affecting IL-8 protein release. All SCFAs dose dependently inhibited NF-κB reporter activity in Colo320DM cells. Propionate dose-dependently suppressed IL-6 mRNA and protein release from colon organ cultures and comparative studies revealed that propionate and butyrate at 30 mmol/L caused a strong inhibition of immune-related gene expression,whereas acetate was less effective. A similar inhibition was achieved with the proteasome inhibitor MG-132,but not the p38 MAPK inhibitor SB203580. All SCFAs decreased IL-6 protein release from organ cultures. CONCLUSION: In the present study propionate and butyrate were equipotent,whereas acetate was less effective,at suppressing NF-κB reporter activity,immune-related gene expression and cytokine release in vitro. Our findings suggest that propionate and acetate,in addition to butyrate,could be useful in the treatment of inflammatory disorders,including IBD.Sofia Tedelind Fredrik Westberg Martin Kjerrulf Alexander Vidal 2007World Journal of Gastroenterology2007,13,20:81
2A case of successful management with splenectomy of intractable ascites due to congenital dyserythropoietic anemia type II-induced cirrhosis显示文摘The congenital dyserythropoietic anemias comprise agroup of rare hereditary disorders of erythropoiesis,characterized by ineffective erythropoiesis as thepredominant mechanism of anemia and by characteristicmorphological aberrations of the majority of erythroblastsin the bone marrow.Congenital dyserythropoieticanemia type II is the most frequent type.All types ofcongenital dyserythropoietic anemias distinctly share ahigh incidence of iron loading.Iron accumulation occurseven in untransfused patients and can result in heartfailure and liver cirrhosis.We have reported about apatient who presented with liver cirrhosis and intractableascites caused by congenital dyserythropoietic anemiatype Ⅱ.Her clinical course was further complicatedby the development of autoimmune hemolyticanemia.Splenectomy was eventually performed whichachieved complete resolution of ascites,increase ofhemoglobin concentration and abrogation of transfusionrequirements.Themistoklis Vassiliadis Vassilia Garipidou Vassilios Perifanis Konstantinos Tziomalos OIga Giouleme Kalliopi Patsiaoura Michalis Avramidis Nikolaos Nikolaidis Sofia Vakalopoulou Ioannis Tsitouridis Antonios Antoniadis Panagiotis Semertzidis Anna Kioumi Evangelos Premetis Nikolaos Eugenidis 2006World Journal of Gastroenterology2006,12,5:47
3Neoadjuvant chemotherapy for gastric cancer. Is it a must or a fake?显示文摘AIM To investigate the neoadjuvant chemotherapy(NAC) effect on the survival of patients with proper stomach cancer submitted to D2 gastrectomy.METHODS We proceeded to a review of the literature with Pub Med, Embase, ASCO and ESMO meeting abstracts as well as computerized use of the Cochrane Library for randomized controlled trials(RCTs) comparing NAC followed by surgery(NAC + S) with surgery alone(SA) for gastric cancer(GC). The primary outcome was the overall survival rate. Secondary outcomes were the site of the primary tumor, extension of node dissection according to Japanese Gastric Cancer Association(JGCA) performed in both arms, disease-specific(DSS) and disease-free survival(DFS) rates, clinical and pathological response rates and resectability rates after perioperative treatment. RESULTS We identified a total of 16 randomized controlled trials comparing NAC + S(n = 1089) with SA(n = 973) published in the period from January 1993-March 2017. Only 6 of these studies were well-designed, structured trials in which the type of lymph node(LN) dissection performed or at least suggested in the trial protocol was reported. Two out of three of the RCTs with D2 lymphadenectomy performed in almost all cases failed to show survival benefit in the NAC arm. Inthe third RCT, the survival rate was not even reported, and the primary end points were the clinical outcomes of surgery with and without NAC. In the remaining three RCTs, D2 lymph node dissection was performed in less than 50% of cases or only recommended in the 'Study Treatment' protocol without any description in the results of the procedure really perfomed. In one of the two studies, the benefit of NAC was evident only for esophagogastric junction(EGJ) cancers. In the second study, there was no overall survival benefit of NAC. In the last trial, which documented a survival benefit for the NAC arm, the chemotherapy effect was mostly evident for EGJ cancer, and more than one-fourth of patients did not have a proper stomach cancer. Additionally, several patients did not receive resectional surgery. Furthermore, the survival rates of international reference centers that provide adequate surgery for homogeneous stomach cancer patients' populations are even higher than the survival rates reported after NAC followed by incomplete surgery.CONCLUSION NAC for GC has been rapidly introduced in international western guidelines without an evidence-based medicinerelated demonstration of its efficacy for a homogeneous population of patients with only stomach tumors submitted to adequate surgery following JGCA guidelines with extended(D2) LN dissection. Additional larger sample-size multicentre RCTs comparing the newer NAC regimens including molecular therapies followed by adequate extended surgery with surgery alone are needed.Rossella Reddavid Silvia Sofia Paolo Chiaro Fabio Colli Renza Trapani Laura Esposito Mario Solej Maurizio Degiuli 2018World Journal of Gastroenterology2018,24,2:25
4Adjusting CA19-9 values to predict malignancy in obstructive jaundice:Influence of bilirubin and C-reactive protein显示文摘AIM:To find a possible relationship between inflammation and CA19-9 tumor marker by analyzing data from patients with benign jaundice(BJ) and malignant jaundice(MJ).METHODS:All patients admitted for obstructive jaundice,in the period 2005-2009,were prospectively enrolled in the study,obtaining a total of 102 patients.On admission,all patients underwent complete standard blood test examinations including C-reactive protein(CRP),bilirubin,CA19-9.Patients were considered eligible for the study when they presented obstructive jaundice confirmed by instrumental examinations and increased serum bilirubin levels(total bilirubin > 2.0 mg/dL).The standard cut-off level for CA19-9 was 32 U/mL,whereas for CRP this was 1.5 mg/L.The CA19-9 level was adjusted by dividing it by the value of serum bilirubin or by the CRP value.The patients were divided into 2 groups,MJ and BJ,and after the adjustment a comparison between the 2 groups of patients was performed.Sensitivity,specificity and positive predictive values were calculated before and after the adjustment.RESULTS:Of the 102 patients,51 were affected by BJ and 51 by MJ.Pathologic CA19-9 levels were found in 71.7% of the patients.In the group of 51 BJ patients there were 29(56.9%) males and 22(43.1%) females with a median age of 66 years(range 24-96 years),whereas in the MJ group there were 24(47%) males and 27(53%) females,with a mean age of 70 years(range 30-92 years).Pathologic CA19-9 serum level was found in 82.3% of MJ.CRP levels were pathologic in 66.6% of the patients with BJ and in 49% with MJ.Bilirubin and CA19-9 average levels were significantly higher in MJ compared with BJ(P = 0.000 and P = 0.02),while the CRP level was significantly higher in BJ(P = 0.000).Considering a CA19-9 cut-off level of 32 U/mL,82.3% in the MJ group and 54.9% in the BJ group were positive for CA19-9(P = 0.002).A CA19-9 cut-off of 100 U/mL increases the difference between the two groups:35.3% in BJ and 68.6% in MJ(P = 0.0007).Adjusting the CA19-9 value by dividing it by serum bilirubin level meant that 21.5% in the BJ and 49% in the MJ group remained with a positive CA19-9 value(P = 0.003),while adjusting the CA19-9 value by dividing it by serum CRP value meant that 31.4% in the BJ group and 76.5% in the MJ group still had a positive CA19-9 value(P = 0.000004).Sensitivity,specificity,positive predictive values of CA19-9 > 32 U/mL were 82.3%,45% and 59.1%;when the cutoff was CA19-9 > 100 U/mL they were,respectively,68.6%,64.7% and 66%.When the CA19-9 value was adjusted by dividing it by the bilirubin or CRP values,these became 49%,78.4%,69.4% and 76.5%,68.6%,70.9%,respectively.CONCLUSION:The present study proposes CRP as a new and useful correction factor to improve the diag-nostic value of the CA19-9 tumor marker in patients with cholestatic jaundice.Gaetano La Greca Maria Sofia Rosario Lombardo Saverio Latteri Agostino Ricotta Stefano Puleo Domenico Russello 2012World Journal of Gastroenterology2012,18,31:20
5Role of radiotherapy in the management of hepatocellular carcinoma:A systematic review显示文摘Many patients with hepatocellular carcinoma(HCC) present with advanced disease,not amenable to curative therapies such as surgery,transplantation or radiofrequency ablation. Treatment options for this group of patients include transarterial chemoembolization(TACE) and radiation therapy. Especially TACE,delivering a highly concentrated dose of chemotherapy to tumor cells while minimizing systemic toxicity of chemotherapy,has given favorable results on local control and survival. Radiotherapy,as a therapeutic modality of internal radiation therapy with radioisotopes,has also achieved efficacious tumor control in advanced disease. On the contrary,the role of external beam radiotherapy for HCC has been limited in the past,due to the low tolerance of surrounding normal liver parenchyma. However,technological innovations in the field of radiotherapy treatment planning and delivery,have provided the means of delivering radical doses to the tumor,while sparing normal tissues. Advanced and highly conformal radiotherapy approaches such as stereotactic body radiotherapy and proton therapy,evaluated for efficacy and safety for HCC,report encouraging results. In this review,we present the role of radiotherapy in hepatocellular carcinoma patients not suitable for radical treatment.Maria-Aggeliki Kalogeridi Anna Zygogianni George Kyrgias John Kouvaris Sofia Chatziioannou Nikolaos Kelekis Vassilis Kouloulias 2015World Journal of Hepatology2015,7,1:18
6Epidermal growth factor receptor and K-Ras in non-small cell lung cancer-molecular pathways involved and targeted therapies显示文摘Lung cancer is currently the leading cause of cancer death in Western nations.Non-small cell lung cancer(NSCLC)represents 80%of all lung cancers,and adenocarcinoma is the predominant histological type.Despite the intensive research carried out on this field and therapeutic advances,the overall prognosis of these patients remains unsatisfactory,with a 5-year overall survival rate of less than 15%.Nowadays,pharmacogenetics and pharmacogenomics represent the key to successful treatment.Recent studies suggest the existence of two distinct molecular pathways in the carcinogenesis of lung adenocarcinoma:one associated with smoking and activation of the K-Ras oncogene and the other not associated with smoking and activation of the epidermal growth factor receptor(EGFR).The K-ras mutation is mainly responsible for primary resistance to new molecules which inhibit tyrosine kinase EGFR(erlotinib and gefitinib)and most of the EGFR mutations are responsible for increased tumor sensitivity to these drugs.This article aims to conduct a systematic review of the literature regarding the molecular pathways involving the EGFR,K-Ras and EGFR targeted therapies in NSCLC tumor behavior.Ramon Andrade de Mello Dania Sofia Marques Rui Medeiros António MF Araújo 2011World Journal of Clinical Oncology2011,2,11:16
7Causes and consequences of microsatellite instability in gastric carcinogenesis显示文摘Loss of DNA mismatch repair(MMR) function, due to somatic or germline epi/genetic alterations of MMR genes leads to the accumulation of numerous mutations across the genome, creating a molecular phenotype known as microsatellite instability(MSI). In gastric cancer(g C), MSI occurs in about 15% to 30% of the cases. This review summarizes the current knowledge on the molecular mechanisms underlying the acquisition of MSI in g C as well as on the clinic, pathologic and molecular consequences of the MSI phenotype. Additionally, current therapeutic strategies for g C and their applicability in the MSI subset are also discussed.Sérgia Velho Maria Sofia Fernandes Marina Leite Ceu Figueiredo Raquel Seruca 2014World Journal of Gastroenterology2014,20,44:14
8Tibolone modulates neuronal plasticity through regulating Tau, GSK3β/Akt/PI3K pathway and CDK5 p35/p25 complexes in the hippocampus of aged male mice显示文摘Aging is a key risk factor for cognitive decline and age-related neurodegenerative disorders. Also, an age-related decrease in sex steroid hormones may have a negative impact on the formation of neurofibrillary tangles(NFTs); these hormones can regulate Tau phosphorylation and the principal kinase GSK3β involved in this process. Hormone replacement therapy decreases NFTs, but it increases the risk of some types of cancer. However, other synthetic hormones such as tibolone(TIB) have been used for hormone replacement therapy. The aim of this work was to evaluate the long-term effects of TIB(0.01 mg/kg and 1 mg/kg, intragastrically for 12 weeks) on the content of total and hyperphosphorylated Tau(PHF-1) proteins and the regulation of GSK3β/Akt/PI3 K pathway and CDK5/p35/p25 complexes in the hippocampus of aged male mice. We observed that the content of PHF-1 decreased with TIB administration. In contrast, no changes were observed in the active form of GSK3β or PI3 K. TIB decreased the expression of the total and phosphorylated form of Akt while increased that of p110 and p85. The content of CDK5 was differentially modified with TIB: it was increased at low doses and decreased at high doses. When we analyzed the content of CDK5 activators, an increase was found on p35; however, the content of p25 decreased with administration of low dose of TIB. Our results suggest a possible mechanism of action of TIB in the hippocampus of aged male mice. Through the regulation of Tau and GSK3β/Akt/PI3 K pathway, and CDK5/p35/p25 complexes, TIB may modulate neuronal plasticity and regulate learning and memory processes.Teresa Neri-Gomez Judith Espinosa-Raya Sofia Diaz Cintra Julia Segura-Uribe Sandra Orozco-Suarez Juan Manuel Gallardo Christian Guerra-Araiza 2017Neural Regeneration Research2017,12,4:12
9Hepatic abscess induced by foreign body:Case report and literature review显示文摘Hepatic abscess due to perforation of the gastrointestinal tract caused by ingested foreign bodies is uncommon. Pre-operative diagnosis is difficult as patients are often unaware of the foreign body ingestion and symptoms and imagiology are usually non-specific. The authors report a case of 62-year-old woman who was admitted with fever and abdominal pain. Further investigation revealed hepatic abscess, without resolution despite antibiotic therapy. A liver abscess resulting from perforation and intra-hepatic migration of a bone coming from the pilorum was diagnosed by surgery. The literature concerning foreign body-induced perforation of the gastrointestinal tract complicated by liver abscess is reviewed.Sofia A Santos Sara CF Alberto Elsa Cruz Eduardo Pires Tomás Figueira lia Coimbra José Estevez Mário Oliveira Luís Novais Joo R Deus 2007World Journal of Gastroenterology2007,13,9:10
10Transcranial direct current stimulation enhances theory of mind in Parkinson’s disease patients with mild cognitive impairment:a randomized,double-blind,sham-controlled study显示文摘Background:Parkinson’s Disease(PD)with mild cognitive impairment(MCI)(PD-MCI)represents one of the most dreaded complications for patients with PD and is associated with a higher risk of developing dementia.Although transcranial direct current stimulation(tDCS)has been demonstrated to improve motor and non-motor symptoms in PD,to date,no study has investigated the effects of tDCS on Theory of Mind(ToM),i.e.,the ability to understand and predict other people’s behaviours,in PD-MCI.Methods:In this randomized,double-blind,sham-controlled study,we applied active tDCS over the medial frontal cortex(MFC)to modulate ToM performance in twenty patients with PD-MCI.Twenty matched healthy controls(HC)were also enrolled and were asked to perform the ToM task without receiving tDCS.Results:In the patients with PD-MCI,i)ToM performance was worse than that in the HC,ii)ToM abilities were poorer in those with fronto-executive difficulties,and iii)tDCS over the MFC led to significant shortening of latency for ToM tasks.Conclusions:We show for the first time that active tDCS over the MFC enhances ToM in patients with PD-MCI,and suggest that non-invasive brain stimulation could be used to ameliorate ToM deficits observed in these patients.Mauro Adenzato Rosa Manenti Ivan Enrici Elena Gobbi Michela Brambilla Antonella Alberici Maria Sofia Cotelli Alessandro Padovani Barbara Borroni Maria Cotelli 2019Translational Neurodegeneration2019,8,1:9
11基于多尺度数字地形定量分析的月球线性构造自动提取研究显示文摘月球表面构造对于理解和重建月球地质构造演化具有重要意义,月岭、月溪等线性构造的形态及分布特征与月球内动力构造运动密切相关。极为有限的样品和难度极高的野外勘察使得遥感成为行星科学研究的最主要手段。中国、美国、日本、印度等国先后发射的多颗新型探月卫星获取了大量高质量数据,尤其是高分辨率的数字地形数据(DTM,Digital Terrain Model)。高分辨率的DTM为月球表面构造特征的自动提取带来了新的机遇与挑战。文中利用多种分辨率的DTM数据,基于多尺度数字地形定量分析方法,识别和提取月球表面的线性构造。使用的地形数据包括500m分辨率'嫦娥一号'激光高度计数据,100m分辨率LRO-WAC广角相机数据,60m分辨率的LRO-LOLA激光测距仪数据以及分辨率高达5m的LRO-NAC窄视角相机数据。文中使用地形曲率来识别月溪月岭等线性构造,并利用不同滑动窗口大小和阈值进行线性构造的自动提取。对研究区试验结果的定量分析表明,文中提出的基于地形曲率的月表线性构造自动提取方法是有效且可行的,其结果可为月球表面线性构造解译提供重要参考,提高构造解译时效性和精度。李珂 陈建平 Paolo TAROLLI Giulia SOFIA 冯增文 李婧 2014地学前缘2014,21,6:9
12Systematic review of the prevalence and development of osteoporosis or low bone mineral density and its risk factors in patients with inflammatory bowel disease显示文摘BACKGROUND The inflammatory bowel diseases(IBD),Crohn’s disease(CD)and ulcerative colitis(UC)are chronic,immune-mediated disorders of the digestive tract.IBD is considered to be a risk factor for developing osteoporosis;however current literature on this matter is inconsistent.AIM To assess prevalence and development of osteoporosis and low bone mineral density(BMD),and its risk factors,in IBD patients.METHODS Systematic review of population-based studies.Studies were identified by electronic(January 2018)and manual searches(May 2018).Databases searched included EMBASE and PubMed and abstracts from 2014-2018 presented at the United European Gastroenterology Week,the European Crohn’s and Colitis Organisation congress,and Digestive Disease Week were screened.Studies were eligible for inclusion if they investigated either the prevalence of osteoporosis or osteopenia and/or risk factors for osteoporosis or low BMD in IBD patients.Studies on children under the age of 18 were excluded.Only population-based studies were included.All risk factors for osteoporosis and low BMD investigated in any included article were considered.Study quality and the possibility of bias were analysed using the Newcastle-Ottawa scale.RESULTS Twelve studies including 3661 IBD patients and 12789 healthy controls were included.Prevalence of osteoporosis varied between 4%-9%in studies including both CD and UC patients;2%-9% in studies including UC patients, and 7%-15% instudies including CD patients. Among healthy controls, prevalence ofosteoporosis was 3% and 10% in two studies. CD diagnosis, lower body massindex (BMI), and lower body weight were risk factors associated withosteoporosis or low BMD. Findings regarding gender showed inconsistent results.CD patients had an increased risk for osteoporosis or low BMD over time, whileUC patients did not. Increased age was associated with decreased BMD, and therewas a positive association between weight and BMI and BMD over time. Greatheterogeneity was found in the included studies in terms of study methodologies,definitions and the assessment of osteoporosis, and only a small number ofpopulation-based studies was available.CONCLUSIONThis systematic review found a possible increase of prevalence of osteoporosis inCD cohorts when compared to UC and cohorts including both disease types.Lower weight and lower BMI were predictors of osteoporosis or low BMD in IBDpatients. The results varied considerably between studies.Sofia Kärnsund Bobby Lo Flemming Bendtsen Jakob Holm Johan Burisch 2020World Journal of Gastroenterology2020,26,35:8
13Post-partum reactivation of chronic hepatitis B virus infection among hepatitis B e-antigen-negative women显示文摘AIM: To investigate the frequency and timing of post-partum chronic hepatitis B virus(HBV) reactivation and identify its pre-partum predictors. METHODS: Forty-one hepatitis B e antigen(HBe Ag)-negative chronic HBV infected pregnant women were prospectively evaluated between the 28 th and the 32 nd week of gestation. Subjects were re-evaluated at 3-mo intervals during the first post-partum year and every 6 mo during the following years. HBV DNA was determined using real-time reverse transcription polymerase chain reaction(Cobas Taq Man HBV Test) with a lower detection limit of 8 IU/m L. Post-partum reactivation(PPR) was defined as abnormal alanine aminotransaminase(ALT) levels and HBV DNA above 2000 IU/m L. RESULTS: Fourteen out of 41 women(34.1%) had prepartum HBV DNA levels > 2000 IU/m L, 18(43.9%) had levels < 2000 IU/m L and 9(21.9%) had undetectable levels. Fourteen women were lost to follow-up(failure to return). PPR occurred in 8 of the 27(29.6%) women evaluated, all within the first 6 mo after delivery(5 at month 3; 3 at month 6). Five of the 6(83.3%) women with pre-partum HBV DNA > 10000 IU/m L exhibited PPR compared with 3 of the 21(14.3%) women with HBV DNA < 10000 IU/m L(two with HBV DNA > 2000 and the third with HBV DNA of 1850IU/m L), P = 0.004. An HBV DNA level ≥ 10000 IU/m L independently predicted post-partum HBV infection reactivation(OR = 57.02, P = 0.033). Mean pre-partum ALT levels presented a non-significant increase in PPR cases(47.3 IU/L vs 22.2 IU/L, respectively, P = 0.094).CONCLUSION: In the present study, PPR occurred in approximately 30% of HBe Ag-negative pregnant women; all events were observed during the first semester after delivery. Pre-partum HBV DNA level > 10000 IU/m L predicted PPR.Ioannis Elefsiniotis Elena Vezali Dimitrios Vrachatis Sofia Hatzianastasiou Stefanos Pappas George Farmakidis Georgia Vrioni Athanasios Tsakris 2015World Journal of Gastroenterology2015,21,4:7
14Irritable bowel syndrome symptom severity improves equally with probiotic and placebo显示文摘AIM To determine the effects of Lactobacillus acidophilus NCFM on irritable bowel syndrome(IBS) symptoms and quality of life(Qo L).METHODS In this randomized triple-blind trial, adult IBS volunteerswho were recruited according to Rome Ⅲ criteria received 109 or 1010 colony-forming units of NCFM or placebo daily for 12 wk. IBS Symptom Severity Score(IBS-SSS), which constituted the primary outcome, and secondary outcomes, including individual IBS symptoms, IBS-related QoL questionnaire, anxiety and depression, defecation frequency, and stool consistency, were assessed at baseline at the end of the 8-wk runin period, after 4 and 12 wk of intervention, and after a 4-wk washout.RESULTS A total of 340 of 391 randomized volunteers completed the trial. IBS-SSS improved over 12 wk of treatment in all treatment groups, decreasing by a mean ± SD of 44.0 ± 80.2, 50.8 ± 82.4, and 48.3 ± 72.2 in the placebo, active low-dose, and active high-dose groups, respectively. Similarly, secondary outcomes did not differ between treatment groups. However, in a post hoc analysis of volunteers with moderate to severe abdominal pain at baseline(VAS > 35/100), the treatment significantly reduced the sensation of abdominal pain. Pain scores fell by 20.8 ± 22.8, 29.4 ± 17.9, and 31.2 ± 21.9 in the placebo, active low-dose, and active high-dose groups, respectively(P value for placebo vs combined active doses = 0.0460).CONCLUSION NCFM alleviates moderate to severe abdominal pain, consistent with earlier observations of this strain mitigating visceral pain through increased analgesic receptor expression.Anna Lyra Markku Hillila Teppo Huttunen Sofia Mannikko Mikko Taalikka Julia Tennila Anneli Tarpila Sampo Lahtinen Arthur C Ouwehand Lea Veijola 2016World Journal of Gastroenterology2016,22,48:7
15Serum MiRNA as Predictive and Prognosis Biomarker in Advanced Stage Non-small Cell Lung Cancer in Indonesia显示文摘Background and objective Lung cancer is the most common cause of death in men in the world and in Indonesia where nonsmall cell carcinoma lung cancer(NSCLC) constitutes 85% of all lung cancer cases. The high mortality rate is due to a poor prognosis and is often diagnosed as having advanced stages. If it is known at the initial stage, the prognosis of lung cancer will be better. Prognosis can be predicted with a marker of prognostic biology, one of which is micro RNA(mi RNA). This study aims to prove that serum mi RNA can be predictive biological marker and prognosis in NSCLC patients in Indonesia.Methods This study was cohort retrospective among 52 subjects in 'Dharmais' Hospital National Cancer Center. Sample was obtained from patients’ serum. Mi R-34, mi R-148, mi R-155 and mi R-222 serum are measured through Real-Time PCR(q PCR). Data were analyzed and interpreted with descriptive analysis, bivariate analysis(Mann Whitney-U for two type of variables or Kruskal-Wallis for more than two type of variables. Kaplan-Meier analysis was used to know association between characteristic which are sociodemographic, performance status, clinico-pathology, and survival rate in mi RNA expression. Results From this study, mi RNA expression: mi R-34(46.15%), mi R-148(23.08%), mi R-155(40.38%) and mi R-222(32.69%). Performance status score was statistically significant correlation with mi R-148(P=0.049) and mi R-222(P=0.018). High mi R-34 is associated with multiple M1 b metastatic type(P=0.020), cancer cell type(adenocarcinoma, P=0.009) and adenocarcinoma epidermal growth factor receptor(EGFR) mutation(negative, P=0.031). There was a significant correlation between the high mi R-222 as a poor prognosis in advanced stage NSCLC with M1 b metastasis(Median Survival/MS: 27 d, P=0.049) and positive EGFR mutations(MS: 74 d, P=0.049) and correlation of mi R-155 with adenocarcinoma(MS: 69 d, P=0.034) and positive EGFR gene mutations(MS: 58 d, P=0.023).Conclusion High mi R-34 expression in advanced stage NSCLC is the predictive factor for multiple metastatic, adenocarcinoma cell type and adenocarcinoma negative EGFR mutation. High expression of mi R-155 and mi R-222 are poor prognoses, especially high mi R-222 found in metastasis M1 b and positive EGFR mutation and mi R-155 found in adenocarcinoma and positive EGFR gene mutations. Further studies regarding correlation between mi RNA and survival rate are needed.Arif R HANAFI Achmad M JAYUSMAN Serafim ALFASUNU Ahmad H SADEWA Dibyo PRAMONO Didik S HERIYANTO Sofia M HARYANA 2020中国肺癌杂志2020,23,5:6
16History and evolution of the use of oral mucosa for urethral reconstruction显示文摘We report here the history and evolution of the use of oral mucosa in reconstructive urethral surgery since it was first used for urethroplasty in 1894.Since that time,many authors have contributed to develop,improve and popularize the use of oral mucosa as a substitute material.Paediatric urologists should be considered pioneers on the use of oral mucosa as they used it to repair primary and failed hypospadias.The use of oral mucosa to repair penile and bulbar urethral strictures was described,for the first time,in 1993.Important evolutions in the technique for harvesting oral mucosa from the cheek were reported in 1996.Today,oral mucosa is considered the gold standard material for any type of anterior urethroplasty in a one-or two-stage repair due to its biological and structural characteristics that make it a highly versatile that is adaptable to any environment required by the reconstructive urethral surgery.As the future approaches,tissue engineering techniques will provide patients with new materials originating from the oral epithelial mucosal cells,which are cultured and expanded into a scaffold.However,the path to reach this ambitious objective is still long and many difficulties must be overcome along the way.Guido Barbagli Sofia Balo Francesco Montorsi Salvatore Sansalone Massimo Lazzeri 2017Asian Journal of Urology2017,4,2:6
17Sequential light programs shape kale (Brassica napus) sproutappearance and alter metabolic and nutrient content显示文摘Different light wavelengths have specific effects on plant growth and development.Narrow-bandwidth light-emitting diode(LED)lighting may be used to directionally manipulate size,color and metabolites in high-value fruits and vegetables.In this report,Red Russian kale(Brassica napus)seedlings were grown under specific light conditions and analyzed for photomorphogenic responses,pigment accumulation and nutraceutical content.The results showed that this genotype responds predictably to darkness,blue and red light,with suppression of hypocotyl elongation,development of pigments and changes in specific metabolites.However,these seedlings were relatively hypersensitive to far-red light,leading to uncharacteristically short hypocotyls and high pigment accumulation,even after growth under very low fluence rates(,1 mmol m^(-2) s^(-1)).General antioxidant levels and aliphatic glucosinolates are elevated by far-red light treatments.Sequential treatments of darkness,blue light,red light and far-red light were applied throughout sprout development to alter final product quality.These results indicate that sequential treatment with narrow-bandwidth light may be used to affect key economically important traits in high-value crops.Sofia D Carvalho Kevin M Folta 2014Horticulture Research2014,1,1:6

19Post-transplantation hepatocellular carcinoma recurrence: Patterns and relation between vascularity and differentiation degree显示文摘AIM: To evaluate the relationship between hepatocellular carcinoma(HCC) vascularity and grade; to describe patterns and vascular/histopathological variations of post-transplantation recurrence.METHODS: This retrospective study included 165 patients(143 men, 22 women; median age 56.8 years, range 28-70.4 years) transplanted for HCC who had a follow-up period longer than 2 mo. Pre-transplantation dynamic computed tomography or magnetic resonance examinations were retrospectively reviewed, classifying HCC imaging enhancement pattern into hypervascular and hypovascular based on presence of wash-in during arterial phase. All pathologic reports of the explanted livers were reviewed, collecting data about HCC differentiation degree. The association between imaging vascular pattern and pathological grade was estimated using the Fisher exact test. All follow-up clinical and imaging data were reviewed for evidence of recurrence. Recurrence rate was calculated and imaging features of recurrent tumor were collected, classifying early and late recurrences based on timing(< or ≥ 2 years after transplantation) and intrahepatic, extrahepatic and both intrahepatic and extrahepatic recurrences based onlocation. All intrahepatic recurrences were classified as hypervascular or hypovascular and the differentiation degree was collected where available. The presence of variations in imaging enhancement pattern and pathological grade between the primary tumor and the intrahepatic recurrence was evaluated and the association between imaging and histopatholgical variations was estimated by using the χ2 test. RESULTS: Of the 163 patients with imaging evidence of viable tumor, 156(95.7%) had hypervascular and 7(4.3%) hypovascular HCC. Among the 125 patients with evidence of viable tumor in the explanted liver, 19(15.2%) had grade 1, 56(44.8%) grade 2, 40(32%) grade 3 and 4(3.2%) grade 4 HCC, while the differentiation degree was not assessable for 6 patients(4.8%). A significant association was found between imaging vascularity and pathological grade(P = 0.035). Post-transplantation recurrence rate was 14.55%(24/165). All recurrences occurred in patients who had a hypervascular primary tumor. Three patients(12.5%) experienced late recurrence; the location of the first recurrence was extrahepatic in 14 patients(58.3%), intrahepatic in 7 patients(29.2%) and both intrahepatic and extrahepatic in 3 patients(12.5%). Two patients had a variation in imaging characteristics between the primary HCC(hypervascular) and the intrahepatic recurrent HCC(hypovascular), while 1 patient had a variation of histopathological characteristics(from moderate to poor differentiation), however no association was found between imaging and histopathological variations.CONCLUSION: A correlation was found between HCC grade and vascularity; some degree of variability may exist between the primary and the recurrence imaging/histopathological characteristics, apparently not correlated.Annarita Pecchi Giulia Besutti Mario De Santis Cinzia Del Giovane Sofia Nosseir Giuseppe Tarantino Fabrizio Di Benedetto Pietro Torricelli 2015World Journal of Hepatology2015,7,2:5
