| 1 | Nutrition and physical activity in NAFLD:An overview of the epidemiological evidence显示文摘Nonalcoholic fatty liver disease(NAFLD)has been recognized as a major health burden.The high prevalence of NAFLD is probably due to the contemporary epidemics of obesity,unhealthy dietary pattern,and sedentary lifestyle.The efficacy and safety profile of pharmacotherapy in the treatment of NAFLD remains uncertain and obesity is strongly associated with hepatic steatosis;therefore,the first line of treatment is lifestyle modification.The usual management of NAFLD includes gradual weight reduction and increased physical activity(PA)leading to an improvement in serum liver enzymes,reduced hepatic fatty infiltration,and,in some cases,a reduced degree of hepatic inflammation and fibrosis.Nutrition has been demonstrated to be associated with NAFLD and Non-alcoholic steatohepatitis(NASH)in both animals and humans,and thus serves as a major route of prevention and treatment.However,most human studies are observational and retrospective,allowing limited inference about causal associations.Large prospective studies and clinical trials are now needed to establish a causal relationship.Based on available data,patients should optimally achieve a 5%-10%weight reduction.Setting realistic goals is essential for long-term successful lifestyle modification and more effort must be devoted to informing NAFLD patients of the health benefits of even a modest weight reduction.Furthermore,all NAFLD patients,whether obese or of normal weight,should be informed that a healthy diet has benefits beyond weight reduction.They should be advised to reduce saturated/trans fat and increase polyunsaturated fat,with special emphasize on omega-3 fatty acids.They should reduce added sugar to its minimum,try to avoid soft drinks containing sugar,including fruit juices that contain a lot of fructose,and increase their fiber intake.For the heavy meat eaters,especially those of red and processed meats,less meat and increased fish intake should be recommended.Minimizing fast food intake will also help maintain a healthy diet.PA should be integrated into behavioral therapy in NAFLD,as even small gains in PA and fitness may have significant health benefits.Potentially therapeutic dietary supplements are vitamin E and vitamin D,but both warrant further research.Unbalanced nutrition is not only strongly associated with NAFLD,but is also a risk factor that a large portion of the population is exposed to.Therefore,it is important to identify dietary patterns that will serve as modifiable risk factors for the prevention of NAFLD and its complications. | Shira Zelber-Sagi Ran Oren Zelber-Sagi Vlad Ratziu | 2011 | World Journal of Gastroenterology2011，17，29： | 33 |
| 2 | Effect of resistance training on non-alcoholic fatty-liver disease a randomized-clinical trial显示文摘AIM:To evaluate the effect of resistance training(RT)on non alcoholic liver disease(NAFLD)patients.METHODS:A randomized clinical trial enrolling NAFLD patients without secondary liver disease(e.g.,without hepatitis B virus,hepatitis C virus or excessive alcohol consumption).Patients were randomly allocated either to RT,three times weekly,for 3 mo or a control arm consisting of home stretching.The RT included leg press,chest press,seated rowing,latissimus pull down etc.with 8-12 repetitions,3 sets for each exercise,for a total duration of 40 min.Hepatic ultrasound,fasting blood tests,anthropometrics and body composition by dual energy X-ray absorptiometry were assessed.At baseline and follow-up,patients filled out a detailed semi-quantitative food frequency questionnaire reporting their habitual nutritional intake.Steatosis was quantified by the hepatorenal-ultrasound index(HRI)representing the ratio between the brightness level of the liver and the right kidney.The HRI has been previously demonstrated to be highly reproducible and was validated against liver biopsy and proton magnetic resonance spectroscopy.RESULTS:Eighty two patients with primary NAFLD were randomized to receive 3 mo of either RT or stretching.After dropout or exclusion from analysis because of protocol violation(weight change>3 kg),thirty three patients in the RT arm and 31 in the stretching arm completed the study per protocol.All baseline characteristics were similar for the two treatment groups with respect to demographics,anthropometrics and body composition,blood tests and liver steatosis on imaging.HRI score was reduced significantly in the RT arm as compared to the stretching arm(-0.25±0.37 vs-0.05±0.28,P=0.017).The RT arm had a significantly higher reduction in total,trunk and android fat with increase in lean body mass.There was no correlation between the reduction in HRI in the RT arm and weight change during the study,but it was positively correlated with the change in trunk fat(r=0.37,P=0.048).The RT arm had a significant reduction in serum ferritin and total cholesterol.There was no significant difference between arms in dietary changes and these did not correlate with HRI change.CONCLUSION:Three months RT improves hepatic fat content accompanied by favorable changes in body composition and ferritin.RT may serve as a complement to treatment of NAFLD. | Shira Zelber-Sagi Assaf Buch Hanny Yeshua Nahum Vaisman Muriel Webb Gil Harari Ofer Kis Naomi Fliss-Isakov Elena Izkhakov Zamir Halpern Erwin Santo Ran Oren Oren Shibolet | 2014 | World Journal of Gastroenterology2014，20，15： | 17 |
| 3 | Trans-arterial chemo-embolization is safe and effective for very elderly patients with hepatocellular carcinoma显示文摘AIM: To assess the safety and efficacy of trans-arterial chemo-embolization (TACE) in very elderly patients. METHODS: A prospective cohort study, from 2001 to 2010, compared clinical outcomes following TACE between patients ≥ 75 years old and younger patients (aged between 65 and 75 years and younger than 65 years) with hepatocellular carcinoma (HCC), diagnosed according to the European Association for the Study of the Liver and the American Association for the Study of Liver Diseases criteria. The decision that patients were not candidates for curative therapy was made by a multidisciplinary HCC team. Data collected included demographics, co-morbidities, liver disease etiology, liver disease severity and the number of procedures. The primary outcome was mortality; secondary outcomes included post-embolization syndrome (nausea, fever, abdominal right upper quadrant pain, increase in liver enzymes with no evidence of sepsis and with a clinical course limited to 3-4 d post procedure) and 30-d complications. Additionally, changes in liver enzyme measurements were assessed [alanine and aspartate aminotransferase (ALT and AST), gamma-glutamyl transpeptidase and alkaline phosphatase] in the week following TACE. Analysis employed both univariate and multivariate methods (Cox regression models). RESULTS: Of 102 patients who underwent TACE as sole treatment, 10 patients (9.8%) were > 80 years old at diagnosis; 13 (12.7%) were between 75 and 80 years, 45 (44.1%) were between 65 and 75 years and 34 (33.3%) were younger than 65 years. Survival analysis demonstrated similar survival patterns between the elderly patients and younger patients. Age was also not associated with the adverse event rate. Survival rates at 1, 2 and 3 years from diagnosis were 74%, 37% and 31% among patients < 65 years; 83%, 66% and 48% among patients aged 65 to 75 years; and 86%, 41% and 23% among patients ≥ 75 years. There were no differences between the age groups in the pre-procedural care, including preventive treatment for contrast nephropathy and prophylactic antibiotics. Multivariate survival analysis, controlling for disease stage at diagnosis with the Barcelona Clinic Liver Cancer score, number of TACE procedures, sex and alphafetoprotein level at the time of diagnosis, found no significant difference in the mortality hazard for elderly vs younger patients, and there were no differences in post-procedural complications. Serum creatinine levels did not change after 55% of the procedures, in all age groups. In 42% of all procedures, serum creatinine levels increased by no more than 25% above the baseline levels prior to TACE. Overall, there were 69 post-embolization events (23%). Hepatocellular enzymes often increased following TACE, with no association with prognosis. In 40% of the procedures, ALT and AST levels rose by at least 100%. The increases in hepatocellular enzymes occurred similarly in all age groups. CONCLUSION: TACE is safe and effective in very elderly patients with HCC, and is not associated with decreased survival or increased complication rates. | Matan J Cohen Allan I Bloom Orly Barak Alexander Klimov Tova Nesher Daniel Shouval Izhar Levi Oren Shibolet | 2013 | World Journal of Gastroenterology2013，19，16： | 13 |
| 4 | Treatment of hepatocellular carcinoma: Steps forward but still a long way to go显示文摘Hepatocellular carcinoma(HCC) is the fifth most common malignancy and the third cause of tumor associated deaths worldwide. HCC incidence rates are increasing in many parts of the world including developing and developed countries. Potentially curative treatments for HCC are resection and liver transplantation, but these are only suitable for patients with small tumors, meeting strict pre-defined criteria, or well-compensated liver disease. Early diagnosis of HCCcan be achieved by surveillance of at-risk populations. For patients with non-resectable disease treatments modalities include loco-ablative and systemic therapies. In this review we focus on treatment options in HCC and their allocation. Although significant research is in progress, to this date, the results are unsatisfactory with limited long-term survival. In the fight against this deadly disease, there is still a long way to go. | Liat Mlynarsky Yoram Menachem Oren Shibolet | 2015 | World Journal of Hepatology2015，7，3： | 13 |
| 5 | Toll-like receptors in inflammatory bowel disease-stepping into uncharted territory显示文摘Ulcerative colitis and Crohn's disease are chronic relapsing-remitting inflammatory processes of the intestinal tract. The etiology of these diseases is currently unknown. However, inflammation is hypothesized to result from inappropriate activation of mucosal immunity by luminal antigens in genetically susceptible individuals. Toll-like receptors (TLRs) are a family of transmembrane proteins that act as microbial pattern recognition receptors. They are crucial initiators of innate immune responses. The role of TLRs in the pathogenesis of inflammatory bowel disease (IBD) has not been fully elucidated. In this review, we aim to analyze the available data connecting individual TLRs to intestinal inflammation and IBD. | Avi Levin Oren Shibolet | 2008 | World Journal of Gastroenterology2008，14，33： | 12 |

| 8 | Oral immune regulation using colitis extracted proteins for treatment of Crohn's disease: Results of a phase Ⅰ clinical trial显示文摘AIM: To evaluate safety and possible efficacy of induction of oral immune regulation using colitis extracted proteins(CEP) in Crohn's disease (CD) subjects.METHODS: Ten CDs were treated orally with autologous CEP thrice weekly for 16 wk. Subjects were monitored for CDAI and IBDQ. Immune modulatory effect was assessed by T-lymphocyte FACS analysis, CEP-specific IFNγ ELISPOT assay and cytokine levels.RESULTS: Induction of oral immune regulation significantly ameliorated disease activity. All (10/10) subjects had clinical response (CDAI≤70) and 7/10 achieved clinical remission (CDAI≤150). Significant increase in mean IBDQ score was noted (134±9vs 164±12). No treatment-related adverse events were noted. High levels of CEP-specific IFNγ spot forming colonies were detected in five subjects prior to treatment and in all five, a marked decrease was observed. The CD4+/CDS+ lymphocyte ratio and peripheral NKT cell numbers increased significantly, in 7/10 and in 5/10 subjects, respectively. Significant increase in serum IL-10 and IL-4 levels was observed in 7/10 subjects during treatment period.CONCLUSION: Immune regulation via oral administration of CEP is a safe and possibly effective treatment for subjects with moderate CD and may provide means of antigen-specific immune modulation. | Eran Israeli Eran Goldin Oren Shibolet Athalia Klein Nilla Hemed Dean Engelhardt Elazar Rabbani Yaron Ilan | 2005 | World Journal of Gastroenterology2005，11，20： | 8 |
| 9 | Comparison of fatty liver index with noninvasive methods for steatosis detection and quantification显示文摘AIM:To compare noninvasive methods presently used for steatosis detection and quantification in nonalcoholic fatty liver disease(NAFLD).METHODS:Cross-sectional study of subjects from the general population,a subgroup from the First Israeli National Health Survey,without excessive alcohol consumption or viral hepatitis.All subjects underwent anthropometric measurements and fasting blood tests.Evaluation of liver fat was performed using four noninvasive methods:the SteatoTest;the fatty liver index(FLI);regular abdominal ultrasound(AUS);and the hepatorenal ultrasound index(HRI).Two of the noninvasive methods have been validated vs liver biopsy and were considered as the reference methods:the HRI,the ratio between the median brightness level of the liver and right kidney cortex;and the SteatoTest,a biochemical surrogate marker of liver steatosis.The FLI is calculated by an algorithm based on triglycerides,body mass index,γ-glutamyl-transpeptidase and waist circumference,that has been validated only vs AUS.FLI < 30 rules out and FLI ≥ 60 rules in fatty liver.RESULTS:Three hundred and thirty-eight volunteers met the inclusion and exclusion criteria and had valid tests.The prevalence rate of NAFLD was 31.1% according to AUS.The FLI was very strongly correlated with SteatoTest(r = 0.91,P < 0.001) and to a lesser but significant degree with HRI(r = 0.55,P < 0.001).HRI and SteatoTest were significantly correlated(r = 0.52,P < 0.001).The κ between diagnosis of fatty liver by SteatoTest(≥ S2) and by FLI(≥ 60) was 0.74,which represented good agreement.The sensitivity of FLI vs SteatoTest was 85.5%,specificity 92.6%,positive predictive value(PPV) 74.7%,and negative predictive value(NPV) 96.1%.Most subjects(84.2%) with FLI < 60 had S0 and none had S3-S4.The κ between diagnosis of fatty liver by HRI(≥ 1.5) and by FLI(≥ 60) was 0.43,which represented only moderate agreement.The sensitivity of FLI vs HRI was 56.3%,specificity 86.5%,PPV 57.0%,and NPV 86.1%.The diagnostic accuracy of FLI for steatosis > 5%,as predicted by SteatoTest,yielded an area under the receiver operating characteristic curve(AUROC) of 0.97(95% CI:0.95-0.98).The diagnostic accuracy of FLI for steatosis> 5%,as predicted by HRI,yielded an AUROC of 0.82(95% CI:0.77-0.87).The κ between diagnosis of fatty liver by AUS and by FLI(≥ 60) was 0.48 for the entire sample.However,after exclusion of all subjects with an intermediate FLI score of 30-60,the κ between diagnosis of fatty liver by AUS and by FLI either ≥ 60 or < 30 was 0.65,representing good agreement.Excluding all the subjects with an intermediate FLI score,the sensitivity of FLI was 80.3% and the specificity 87.3%.Only 8.5% of those with FLI < 30 had fatty liver on AUS,but 27.8% of those with FLI ≥ 60 had normal liver on AUS.CONCLUSION:FLI has striking agreement with SteatoTest and moderate agreements with AUS or HRI.However,if intermediate values are excluded FLI has high diagnostic value vs AUS. | Shira Zelber-Sagi Muriel Webb Nimer Assy Laurie Blendis Hanny Yeshua Moshe Leshno Vlad Ratziu Zamir Halpern Ran Oren Erwin Santo | 2013 | World Journal of Gastroenterology2013，19，1： | 8 |
| 10 | Minimizing treatment complexity of combat-related soft tissue injuries using a dedicated tension relief system and negative pressure therapy augmented by high-dose in situ antibiotic therapy and oxygen delivery: a retrospective study显示文摘Background:Following combat-related,extensive soft tissue injury from gunshot wounds or blasts,prolonged duration from injury to full wound closure is associated with infection,increased morbidity and mortality,failure to mobilize,poor functional outcome and increased cost.The purpose of this study was to evaluate a novel treatment enabling early primary closure of combat wounds.Methods:This was a retrospective study of 10 soldiers and civilians with extensive combat-related soft tissue limb injuries(5 gunshot wounds,5 blasts)treated using the TopClosure^(■)Tension Relief System(TRS)with simultaneous administration of regulated oxygen-enriched and irrigation negative pressure-assisted wound therapy(ROINPT)via the Vcareα^(■)device.Results:Nine patients were treated during the acute phase of injury and one was treated following removal of a flap due to deep infection 20 years after injury and flap reconstruction.Two patients had upper limb injury and the rest lower limb injury.With the aid of the TRS and/or ROINPT,immediate primary closure during reconstruction was achieved in 6 patients and delayed primary closure in three.Only one patient required a skin graft to close a small area of the wound after most of the wound had been closed by delayed primary closure.Wound closure was achieved within 0–37 days(median:12.5 days,interquartile range:2.75–19.75)from injury.Conclusions:The TRS is a novel device for effective,early skin stretching and secure wound closure through the application of stress relaxation and mechanical creep,achieving primary closure of large defects using a simplified surgical technique and reducing the need for closure using skin grafts and flaps and the use of tissue expanders.Delivering supplemental oxygen to the wound by ROINPT reverses the reduced oxygen levels inherent in conventional negative pressure-assisted wound therapy,mitigating anaerobic contamination and reducing infection.Irrigation may accelerate the evacuation of infectious material from the wound and provide a novel method for antibiotic administration.The combination of TRS and ROINPT devices allow for early primary closure with improved functionality of combat-related limb injuries. | Moris Topaz Itamar Ashkenazi Oren Barzel Seema Biswas Dan Atar Nurit Shadmi Itzhak Siev-Ner | 2021 | Burns & Trauma2021，9，1： | 7 |

| 12 | Hepatocellular carcinoma in the post-hepatitis C virus era: Should we change the paradigm?显示文摘Hepatocellular carcinoma (HCC) is a common and deadly malignancy. The disease usually develops on a background of chronic liver disease. Until recently, the most common etiology was infection with the hepatitis C virus (HCV). The advent of direct-acting antiviral (DAA) therapies has been a major breakthrough in HCV treatment. Sustained virologic response can now be achieved in almost all treated patients, even in patients with a high risk for the development of HCC, such as the elderly or those with significant fibrosis. Early reports raised concerns of a high risk for HCC occurrence after DAA therapy both in patients with previous resection of tumors and those without previous tumors. As the World Health Organization’s goals for eradication of HCV are being endorsed worldwide, the elimination of HCV seems feasible. Simultaneous to the decrease in the burden of cirrhosis from HCV, non-alcoholic fatty liver disease (NAFLD) incidence has been increasing dramatically including significant increased incidence of cirrhosis and HCC in these patients. Surprisingly, a substantial proportion of patients with NAFLD were shown to develop HCC even in the absence of cirrhosis. Furthermore, HCC treatment and potential complications are known to be influenced by liver steatosis. These changes in etiology and epidemiology of HCC suggest the beginning of a new era: The post–HCV era. Changes may eventually undermine current practices of early detection, surveillance and management of HCC. We focused on the risk of HCC occurrence and recurrence in the post–HCV era, the surveillance needed after DAA therapy and current studies in HCC patients with NAFLD. | Hadar Meringer Oren Shibolet Liat Deutsch | 2019 | World Journal of Gastroenterology2019，25，29： | 6 |
| 13 | 颈髓电刺激参数对脑血流增加的影响显示文摘目的观察颈髓电刺激(SCS)参数和刺激持续时间对脑血流(CBF)的影响。方法以不同波幅、波宽、频率组合的电流刺激大鼠颈髓(C_1/C_2)2 min,同时采用激光多普勒(LDF)记录CBF,得出一个引起LDF值最大化增加的刺激参数(△%LDF)后,再将刺激时间延长至20 min。结果刺激波幅、波宽和频率分别设定为1.5 mA、0.25 ms和50 Hz是SCS升CBF的最佳参数,按以上参数设定后,延长刺激持续时间至20 min,△%LDF在整个刺激时段均保持较高水平。2、5、10及20 min的△%LDF依次为(67.6±2.7)%、(66.2±3.4)%、(61.7±2.4)%和(52.4±2.3)%;前3个时间点△%LDF值的差异无统计学意义(P值均>0.05),最后1个时间点△%LDF值则略有下降(P<0.01),但仍显著高于对照动物(P<0.01)。结论SCS能增加CBF,其效应不随刺激时间延长而消失,SCS有可能成为治疗脑缺血的一种方法。 | 仲骏 Sagher Oren | 2007 | 上海医学2007，30，7： | 6 |
| 14 | Role of illness perception and self-efficacy in lifestyle modification among non-alcoholic fatty liver disease patients显示文摘AIM To describe the relationships between non-alcoholic fatty-liver disease(NAFLD) patient's disease consequences and treatment perceptions, self-efficacy, and healthy lifestyle maintenance. METHODS A cross-sectional study among 146 ultrasound diagnosed NAFLD patients who visited the fatty liver clinic at the TelAviv Medical Center. Eighty-seven of these individuals, participated in a clinical trial of physical activity and underwent fasting blood tests, analyzed at the same lab. Exclusion criteria included positivity for serum HBsA g or anti-HCV antibodies; fatty liver suspected to be secondary to hepatotoxic drugs; excessive alcohol consumption(≥ 30 g/d in men or ≥ 20 g/d in women) and positive markers of genetic or immune-mediated liver diseases. Patients were asked to complete a selfreport structured questionnaire, assembled by the Israeli Center for Disease Control. Nutrition habits were measured using six yes/no questions(0 = no, 1 = yes) adopted from the national survey questionnaire. Participants in the clinical trial completed a detailed semi-quantitative food frequency questionnaire(FFQ) reporting their habitual nutritional intake during the past year. Self-efficacy was assessed by the Self-Efficacy Scale questionnaire, emotional representation, degree of illness understanding, timeline perception, treatment perception and symptoms were measured by the Brief Illness Perception questionnaire. Illness consequences were measured by the Personal Models of Diabetes Interview questionnaire. A path analysis was performed to describe the interrelationships between the patients' illness perceptions, and assess the extent to which the data fit a prediction of nutritional habits.RESULTS The study sample included 54.1% men, with a mean age of 47.76 ± 11.68 years(range: 20-60) and mean body mass index of 31.56 ± 4.6. The average perceived nutrition habits score was 4.73 ± 1.45 on a scale between 0-6, where 6 represents the healthiest eating habits. Most of the study participants(57.2%) did not feel they fully understood what NAFLD is. Better nutritional habits were positively predicted by the degree of illness understanding(β = 0.26; P = 0.002) and selfefficacy(β = 0.25; P = 0.003). Perceptions of more severe illness consequences were related with higher emotional representation(β = 0.55; P < 0.001), which was related with lower self-efficacy(β =-0.17; P = 0.034). The perception of treatment effectiveness was positively related with self-efficacy(β = 0.32; P < 0.001). In accordance with the correlation between self-efficacy and the perceived nutrition habits score, self-efficacy was also correlated with nutrient intake evaluated by the FFQ; negatively with saturated fat(percent of saturated fat calories from total calories)(r =-0.28, P = 0.010) and positively with fiber(r = 0.22, P = 0.047) and vitamin C intake(r = 0.34, P = 0.002). In a sub analysis of the clinical trial participants, objectively measured compliance to physical activity regimen was positively correlated with the self-efficacy level(r = 0.34, P = 0.046). CONCLUSION Self-efficacy and illness understanding are major determinants of lifestyle-modification among NAFLD patients. This information can assist clinicians in improving compliance with lifestyle changes among these patients. | Shira Zelber-Sagi Shiran Bord Gali Dror-Lavi Matthew Lee Smith Samuel D Towne Jr Assaf Buch Muriel Webb Hanny Yeshua Assy Nimer Oren Shibolet | 2017 | World Journal of Gastroenterology2017，23，10： | 6 |

| 16 | Cementomimetics——constructing a cementum-like biomineralized microlayer via amelogenin-derived peptides显示文摘Cementum is the outer-,mineralized-tissue covering the tooth root and an essential part of the system of periodontal tissue that anchors the tooth to the bone. Periodontal disease results from the destructive behavior of the host elicited by an infectious biofilm adhering to the tooth root and left untreated,may lead to tooth loss. We describe a novel protocol for identifying peptide sequences from native proteins with the potential to repair damaged dental tissues by controlling hydroxyapatite biomineralization. Using amelogenin as a case study and a bioinformatics scoring matrix,we identified regions within amelogenin that are shared with a set of hydroxyapatite-binding peptides (HABPs) previously selected by phage display. One 22-amino acid long peptide regions referred to as amelogenin-derived peptide 5 (ADP5) was shown to facilitate cell-free formation of a cementum-like hydroxyapatite mineral layer on demineralized human root dentin that,in turn,supported attachment of periodontal ligament cells in vitro. Our findings have several implications in peptide-assisted mineral formation that mimic biomineralization. By further elaborating the mechanism for protein control over the biomineral formed,we afford new insights into the evolution of protein-mineral interactions. By exploiting small peptide domains of native proteins,our understanding of structure-function relationships of biomineralizing proteins can be extended and these peptides can be utilized to engineer mineral formation. Finally,the cementomimetic layer formed by ADP5 has the potential clinical application to repair diseased root surfaces so as to promote the regeneration of periodontal tissues and thereby reduce the morbidity associated with tooth loss. | Mustafa Gungormus Ersin E Oren Jeremy A Horst Hanson Fong Marketa Hnilova Martha J Somerman Malcolm L Snead Ram Samudrala Candan Tamerler Mehmet Sarikaya | 2012 | International Journal of Oral Science2012，4，2： | 5 |
| 17 | Expression of Mitochondrial Gene Fragments within the Tapetum Induce Male Sterility by Limiting the Biogenesis of the Respiratory Machinery in Transgenic Tobacco显示文摘Plant mitochondrial genomes (mtDNAs) are large and undergo frequent recombination events. A common phenotype that emerges as a consequence of altered mtDNA structure is cytoplasmic-male sterility (CMS). The molecular basis for CMS remains unclear, but it seems logical that altered respiration activities would result in reduced pollen production. Analysis of tobacco (Nicotiana tabacum) mtDNAs indicated that CMS-associated loci often contain fragments of known organellar genes. These may assemble with organellar complexes and thereby interfere with normal respiratory functions. Here, we analyzed whether the expression of truncated fragments of mitochondrial genes (i.e. atp4, cox1 and rps3) may induce male sterility by limiting the biogenesis of the respiratory machinery. cDNA fragments corresponding to atp4f, cox1f and rps3f were cloned in-frame to a mitochondrial localization signal and a C-termini HA-tag under a tapetum-specific promoter and introduced to tobacco plants by Agrobacterium-mediated transformation. The constructs were then analyzed for their effect on mitochondrial activity and pollen fertility. Atp4f , Cox1f and Rps3f plants demonstrated male sterility phenotypes, which were tightly correlated with the expression of the recombinant fragments in the floral meristem. Fractionation of native organellar extracts showed that the recombinant ATP4f-HA, COX1f-HA and RPS3f-HA proteins are found in large membrane-associated particles.

| 18 | Crohn’s and colitis in children and adolescents显示文摘Crohn's disease and ulcerative colitis can be grouped as the inflammatory bowel diseases(IBD).These conditions have become increasingly common in recent years,including in children and young people.Although much is known about aspects of the pathogenesis of these diseases,the precise aetiology is not yet understood,and there remains no cure.Recent data has illustrated the importance of a number of genes-several of these are important in the onset of IBD in early life,including in infancy.Pain,diarrhoea and weight loss are typical symptoms of paediatric Crohn's disease whereas bloody diarrhoea is more typical of colitis in children.However,atypical symptoms may occur in both conditions:these include isolated impairment of linear growth or presentation with extra-intestinal manifestations such as erythema nodosum.Growth and nutrition are commonly compromised at diagnosis in both Crohn's disease and colitis.Consideration of possible IBD and completion of appropriate investi-gations are essential to ensure prompt diagnosis,thereby avoiding the consequences of diagnostic delay.Patterns of disease including location and progression of IBD in childhood differ substantially from adultonset disease.Various treatment options are available for children and adolescents with IBD.Exclusive enteral nutrition plays a central role in the induction of remission of active Crohn's disease.Medical and surgical therapies need to considered within the context of a growing and developing child.The overall management of these chronic conditions in children should include multi-disciplinary expertise,with focus upon maintaining control of gut inflammation,optimising nutrition,growth and quality of life,whilst preventing disease or treatment-related complications. | Andrew S Day Oren Ledder Steven T Leach Daniel A Lemberg | 2012 | World Journal of Gastroenterology2012，18，41： | 4 |
| 19 | 脊髓电刺激增加脑血流的作用机制显示文摘目的从脑血管的交感和副交感通路探讨脊髓电刺激(SCS)对脑血流影响的机制。方法SD大鼠分5组:对照组(n=14,不对神经纤维和神经节作任何手术处理)、V1组(n=9,切断双侧鼻睫状神经及其副交感节后纤维)、SCG组(n=8,切断双侧颈上神经节)、V1+SCG组(n=9,切断双侧鼻睫状神经及其副交感节后纤维和双侧颈上神经节)、假手术组(n=11,手术暴露双侧鼻睫状神经及其副交感节后纤维和双侧颈上神经节,但不切断神经纤维或神经节);给予大鼠SCS,并用激光多普勒(LDF)实时记录脑血流。结果SCS时LDF测量值的变化在对照组、V1组和SCG组间比较,差异无统计学意义(P>0.05);在V1+SCG组,SCS的升脑血流效应被明显抑制。结论SCS的升脑血流效应可能是通过交感和副交感双重通路实现的。 | 朱晋 仲骏 SAGHER Oren | 2008 | 上海交通大学学报(医学版)2008，28，8： | 4 |
| 20 | Framework of behavioral indicators evaluating TB health promotion outcomes: a modified Delphi study of TB policymakers and health workers显示文摘Background:Although TB health promotion directed at policy makers and healthcare workers(HCWs)is considered important to tuberculosis(TB)control,no indicators currently assess the impact of such promotional activities.This article is the second in a series of papers that seek to establish a framework of behavioral indicators for outcome evaluation of TB health promotion,using the Delphi method.In the first article,we sought to establish a framework of behavioral indicators for outcome evaluation of TB health promotion among TB suspects and patients.The objective of this second article is to present an indicator framework that can be used to assess behavioral outcomes of TB health promotion directed at policy makers and HCWs.Methods:A two-round,modified Delphi method was used to establish the indicators.Sixteen experts who were knowledgeable and experienced in the field of TB control were consulted in Delphi surveys.A questionnaire was developed following 4 steps,and involved ranking indicators on a five-point Likert scale.The consensus level was 70%.Median,mode,and Coefficient of variation(CV)were used to describe expert responses.An authority coefficient(Cr)was used to assess the degree of each expert’s authority.Results:Consensus was achieved following the two survey rounds and several iterations among the experts.For TB health-promotion activities directed at policymakers,the experts reached consensus on 2 domains(“Resource inputs”and“Policymaking and monitoring behaviors”),4 subdomains(“Human resources”among others),and 13 indicators(“Human resources per 100,000 person”among others).For TB health-promotion activities directed at HCWs,the experts reached consensus on 5 domains(“Self-protective behaviors”among others),6 sub-domains(“Preventing infection”among others),and 15 indicators(“Average hours of daily workplace disinfection by ultraviolet radiation”among others).Conclusions:This study identified a conceptual framework of core behavioral indicators to evaluate TB health-promotion activities directed at policymakers and HCWs involved in TB control.Validation in other parts of the world could lead to global consensus on behavioral indicators to evaluate TB health promotion targeted at policymakers and HCWs. | Ying Li John Ehiri Daiyu Hu Eyal Oren Jia Cao | 2015 | Infectious Diseases of Poverty2015，4，1： | 4 |
