| 1 | Correlation of N-myc downstream-regulated gene 1 expression with clinical outcomes of colorectal cancer patients of different race/ethnicity显示文摘AIM: To evaluate the role of N-myc downstream-regulated gene 1 (NDRG1) expression in prognosis and survival of colorectal cancer patients with different ethnic backgrounds. METHODS: Because NDRG1 is a downstream target of p53 and hypoxia inducible factor-1α (HIF-1α),we examined NDRG1 expression together with p53 and HIF-1α by immunohistochemistry. A total of 157 colorectal cancer specimens including 80 from Japanese patients and 77 from US patients were examined. The correlation between protein expression with clinicopathological features and survival after surgery was analyzed.in colorectal tumor compared with normal epithelium in both Japanese and US patient groups. Expression of NDRG1 protein was significantly correlated with lymphatic invasion,venous invasion,depth of invasion,histopathological type,and Dukes' stage in Japanese colorectal cancer patients. NDRG1 expression was correlated to histopathological type,Dukes' stage and HIF-1α expression in US-Caucasian patients but not in US-African American patients. Interestingly,Kaplan-Meier survival analysis demonstrated that NDRG1 expression correlated significantly with poorer survival in US-African American patients but not in other patient groups. However,in p53-positive US cases,NDRG1 positivity correlated significantly with better survival. In addition,NDRG1 expression also correlated significantly with improved survival in US patients with stages Ⅲ and Ⅳ tumors without chemotherapy. In Japanese patients with stages Ⅱ and Ⅲ tumors,strong NDRG1 staining in p53-positive tumors correlated significantly with improved survival but negatively in patients without chemotherapy. CONCLUSION: NDRG1 expression was correlated with various clinicopathological features and clinical outcomes in colorectal cancer depending on the race/ethnicity of the patients. NDRG1 may serve as a biological basis for the disparity of clinical outcomes of colorectal cancer patients with different ethnic backgrounds. | Minori Koshiji Kensuke Kumamoto Keiichirou Morimura Yasufumi Utsumi Michiko Aizawa Masami Hoshino Shinji Ohki Seiichi Takenoshita Max Costa Thérèse Commes David Piquemal Curtis C Harris Kam-Meng Tchou-Wong | 2007 | World Journal of Gastroenterology2007，13，20： | 25 |
| 2 | 世界卫生组织(WHO)造血与淋巴组织肿瘤分类方案:临床顾问委员会会议报告显示文摘引言 :从 1995年开始 ,欧洲病理学工作者协会和血液病理学会一直致力于制定一个新的世界卫生组织 (WHO)血液恶性肿瘤分类方案 ,该分类方案包括淋巴系肿瘤、髓系肿瘤、组织细胞肿瘤和肥大细胞肿瘤。 材料与方法 :此项 WHO计划共组成十个病理学工作者委员会 ,负责确定病种和作出定义。另外还成立一个由国际血液学家和肿瘤学家组成的临床顾问委员会 (CAC)以保证该分类的临床实用性。 1997年 11月召开会议讨论了与该分类有关的临床问题。 结果 :WHO采纳了 1994年国际淋巴瘤研究组 (IL SG)报告的修订欧美淋巴系肿瘤分类 (REAL)方案作为淋巴系肿瘤的分类方案。该方案的分类方法遵循以下原则 :分类应是联合应用形态学、免疫表型、遗传特征及临床特征能够清楚界定的“真实存在”(“real”)病种的名录 ,上述各项特征的相对重要性因病种不同而异 ,不存在任何“金标准”。 WHO将 REAL分类原则延用于髓系肿瘤和组织细胞肿瘤 ,髓系肿瘤的分类包括联合应用细胞形态学和细胞遗传学异常能够界定的各个病种。围绕一系列临床问题召集的这次 CAC会议 ,就提交的大多数问题达成共识 ,这些问题及共识将详述于下。对于另外一些问题 ,CAC认为淋巴系肿瘤临床分组既无必要也不必需 ,患者的治疗取决于淋巴瘤的具体类型 ,如有? | N L Harris E S Jaffe J Diebold G Flandrin H K Muller-Hermelink J Vardiman T A Lister C D Bloomfield 张凤奎 郝玉书 | 2001 | 白血病.淋巴瘤2001，10，3： | 20 |
| 3 | Cyclooxygenase-2 and the inflammogenesis of breast cancer显示文摘Cohesive scientific evidence from molecular, animal, and human investigations supports the hypothesis that constitutive overexpression of cyclooxygenase-2(COX-2) is a ubiquitous driver of mammary carcinogenesis, and reciprocally, that COX-2 blockade has strong potential for breast cancer prevention and therapy. Key findings include the following:(1) COX-2 is constitutively expressed throughout breast cancer development and expression intensifies with stage at detection, cancer progression and metastasis;(2) essential features of mammary carcinogenesis(mutagenesis, mitogenesis, angiogenesis, reduced apoptosis, metastasis and immunosuppression) are linked to COX-2-driven prostaglandin E2(PGE-2) biosynthesis;(3) upregulation of COX-2 and PGE-2 expression induces transcription of CYP-19 and aromatase-catalyzed estrogen biosynthesis which stimulates unbridled mitogenesis;(4) extrahe-patic CYP-1B1 in mammary adipose tissue converts paracrine estrogen to carcinogenic quinones with mutagenic impact; and(5) agents that inhibit COX-2 reduce the risk of breast cancer in women without disease and reduce recurrence risk and mortality in women with breast cancer. Recent sharp increases in global breast cancer incidence and mortality are likely driven by chronic inflammation of mammary adipose and upregulation of COX-2 associated with the obesity pandemic. The totality of evidence clearly supports the supposition that mammary carcinogenesis often evolves as a progressive series of highly specific cellular and molecular changes in response to induction of constitutive overexpression of COX-2 and the prostaglandin cascade in the 'inflammogenesis of breast cancer'. | Randall E Harris Bruce C Casto Zachary M Harris | 2014 | World Journal of Clinical Oncology2014，5，4： | 15 |

| 5 | Recurrent ectopic pancreatitis of the jejunum and mesentery over a 30-year period显示文摘BACKGROUND:Ectopic pancreas is defined as pancreatic tissue found outside its usual anatomical position,with no ductal or vascular communication with the native pancreas. We describe a case of ectopic pancreas of the small bowel and mesentery causing recurrent episodes of pancreatitis, initially suspected on computed tomography(CT)and magnetic resonance cholangiopancreatography(MRCP),and confirmed on histological review of the resection. METHODS:A 67-year-old woman presented with clinical symptoms and biochemical evidence of pancreatitis.She had similar episodes over the past 30 years with unrevealing investigations,and was concluded to have idiopathic pancreatitis. She underwent CT and MRCP,with findings suggestive of ectopic pancreas,a diagnosis confirmed on histology of the resection. RESULTS:MRCP identified a mass in the proximal small bowel mesentery isointense to the native pancreas,with a small duct draining into a proximal jejunal loop.The resected specimen consisted of normal parenchyma with lobulated acinar tissue with scattered islets of Langerhans,an occasional ductular structure,and admixed areas of adipose tissue.The patient remained asymptomatic with normal biochemistry six months post-operatively. CONCLUSION:In an individual with abdominal pain,elevated serum amylase/lipase,but imaging findings of a normal native pancreas,ectopic pancreatitis should be considered,and can be evaluated by CT and MRCP. | John CT Wong Charlotte Robinson Edward C Jones Alison Harris Charles Zwirewich Robert Wakefield Richard K Simons Eric M Yoshida | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，2： | 4 |

| 8 | Machine learning models compared to existing criteria for noninvasive prediction of endoscopic retrograde cholangiopancreatography-confirmed choledocholithiasis显示文摘Background and aims:Noninvasive predictors of choledocholithiasis have generally exhibited marginal performance characteristics.We aimed to identify noninvasive independent predictors of endoscopic retrograde cholangiopancreatography(ERCP)-confirmed choledocholithiasis and accordingly developed predictive machine learning models(MLMs).Methods:Clinical data of consecutive patients undergoing first-ever ERCP for suspected chol-edocholithiasis from 2015 to 2019 were abstracted from a prospectively-maintained database.Multiple logistic regression was used to identify predictors of ERCP-confirmed choledocholithiasis.MLMs were then trained to predict ERCP-confirmed choledocholithiasis using pre-ERCP ultrasound(US)imaging only as well as using all available noninvasive imaging(US,computed tomography,and/or magnetic reso-nance cholangiopancreatography).The diagnostic performance of American Society for Gastrointestinal Endoscopy(ASGE)“high-likelihood”criteria was compared to MLMs.Results:We identified 270 patients(mean age 46 years,62.2%female,73.7%Hispanic/Latino,59%with noninvasive imaging positive for choledocholithiasis)with native papilla who underwent ERCP for suspected choledocholithiasis,of whom 230(85.2%)were found to have ERCP-confirmed chol-edocholithiasis.Logistic regression identified choledocholithiasis on noninvasive imaging(odds ratio(OR)¼3.045,P¼0.004)and common bile duct(CBD)diameter on noninvasive imaging(OR¼1.157,P¼0.011)as predictors of ERCP-confirmed choledocholithiasis.Among the various MLMs trained,the random forest-based MLM performed best;sensitivity was 61.4%and 77.3%and specificity was 100%and 75.0%,using US-only and using all available imaging,respectively.ASGE high-likelihood criteria demonstrated sensitivity of 90.9%and specificity of 25.0%;using cut-points achieving this specificity,MLMs achieved sensitivity up to 97.7%.Conclusions:MLMs using age,sex,race/ethnicity,presence of diabetes,fever,body mass index(BMI),total bilirubin,maximum CBD diameter,and choledocholithiasis on pre-ERCP noninvasive imaging predict ERCP-confirmed choledocholithiasis with good sensitivity and specificity and outperform the ASGE criteria for patients with suspected choledocholithiasis. | Camellia Dalai John M Azizian Harry Trieu Anand Rajan Formosa C Chen Tien Dong Simon W Beaven James H.Tabibian | 2021 | Liver Research2021，5，4： | 3 |
| 9 | Bone and high-density lipoprotein:The beginning of a beautiful friendship显示文摘There is a tight link between bone and lipid metabolic pathways.In this vein,several studies focused on the exploration of high-density lipoprotein(HDL)in the pathobiology of bone diseases,with emphasis to the osteoarthritis(OA)and osteoporosis,the most common bone pathologies.Indeed,epidemiological and in vitro data have connected reduced HDL levels or dysfunctional HDL with cartilage destruction and OA development.Recent studies uncovered functional links between HDL and OA fueling the interesting hypothesis that OA could be a chronic element of the metabolic syndrome.Other studies have linked HDL to bone mineral density.Even though at epidemiological levels the results are conflicting,studies in animals as well as in vitro experiments have shown that HDL facilitates osteoblastogensis and bone synthesis and most probably affects osteoclastogenesis and osteoclast bone resorption.Notably,reduced HDL levels result in increased bone marrow adiposity affecting bone cells function.Unveiling the mechanisms that connect HDL and bone/cartilage homeostasis may contribute to the design of novel therapeutic agents for the improvement of bone and cartilage quality and thus for the treatment of related pathological conditions. | Dionysios J Papachristou Harry C Blair | 2016 | World Journal of Orthopedics2016，7，2： | 3 |
