1美国国立老化研究所与阿尔茨海默病协会诊断指南写作组:阿尔茨海默病临床前阶段的定义显示文摘阿尔茨海默病(AD)的病理生理过程在痴呆诊断的多年前就开始了。这一长期的AD“临床前”阶段是治疗干预的关键机会,但需进一步阐明AD的病理级联过程和临床症状出现之间的联系。美国国立老化研究所和AD协会召集了一个国际工作组对AD生物标志物、流行病学和神经心理学的证据进行综述并提出建议,以确定能够预测由“正常”认知到轻度认知功能障碍(MCI)及AD痴呆的最佳预测指标。根据目前已有的主要科学证据,我们提出了一个概念性的框架和用于操作的研究标准,以通过纵向临床研究来验证和改进这些模型。这些建议仅用于研究目的,目前不涉及临床应用。我们希望这些建议能提供一个共识,以推进临床前AD的研究,最终推动更早期治疗干预的进展,使得一些疾病减缓药物的疗效发挥最大。Sperling RA Aisen PS Beckett LA Bennett DA Craft S Fagan AM Iwatsubo T Jack CR Jr Kaye J Montine TJ Park DC Reiman EM Rowe CC Siemers E Stern Y Yaffe K Carrillo MC Thies B Morrison-Bogorad M Wagster MV Phelps CH 贾建平(译) 郭起浩(译) 黄丽(译) 陆璐(译) 张逸驰(译) 邢怡(译) 2012中华神经科杂志2012,45,5:22
2High level of preoperative carbohydrate antigen 19-9 is a poor survival predictor in gastric cancer显示文摘AIM:To assess the clinical significance and the prognostic value of preoperative serum carbohydrate antigen 19-9(CA 19-9)level in gastric cancer.METHODS:Between January 2005 and December2006,1960 patients underwent surgery for histologically confirmed gastric cancer.Of these,163 patients had elevated serum levels of CA 19-9 preoperatively,and1628 patients had normal serum levels of CA 19-9 preoperatively.For this study,325 patients were selected from the group of 1628 patients by age,sex,and cancer stage to serve as controls.Statistically significant differences in survival rates were calculated using the log-rank test.A P value less than 0.05 was considered statistically significant and was determined using SAS software.RESULTS:The baseline characteristics showed some differences between the two groups with regard to histology.Overall survival(OS)in the elevated and nonelevated group was 37.90 and 68.67 mo,respectively(P<0.001).N stage(P=0.001)was a significant predictor of disease-free survival by multivariate analysis.Also,N stage(P<0.001),and the presence of peritoneal metastasis(P<0.001)remained independent factors in predicting OS by multivariate analysis.Additionally,preoperative serum CA 19-9 levels were significantly associated with OS in univariate(P=0.009)and multivariate(P=0.021)analyses.CONCLUSION:Serum CA 19-9 can be considered an independent prognostic factor in predicting OS in patients anticipating surgery for gastric cancer.A Ra Choi Jun Chul Park Jie-Hyun Kim Sung Kwan Shin Sang Kil Lee Yong Chan Lee Jae Bock Chung 2013World Journal of Gastroenterology2013,19,32:8

5A case of hypereosinophilic syndrome presenting with intractable gastric ulcers显示文摘We report a rare case of hypereosinophilic syndrome(HES)presenting with intractable gastric ulcers.A 71-year-old man was admitted with epigastric pain.Initial endoscopic findings revealed multiple,active gastric ulcers in the gastric antrum.He underwent Helicobacter pylori(H pylori)eradication therapy followed by proton pump inhibitor(PPI)therapy.However,follow-up endoscopy at 4,6,10 and 14 mo revealed persistent multiple gastric ulcers without significant improvement.The proportion of his eosinophil count increased to 43%(total count:7903/mm 3).Abdominal-pelvic and chest computed tomography scans showed multiple small nodules in the liver and both lungs.The endoscopic biopsy specimen taken from the gastric antrum revealed prominent eosinophilic infiltration,and the liver biopsy specimen also showed eosinophilic infiltration in the portal tract and sinusoid.A bone marrow biopsy disclosed eosinophilic hyperplasia as well as increased cellularity of 70%.The patient was finally diagnosed with HES involving the stomach,liver,lung,and bone marrow.When gastric ulcers do not improve despite H pylori eradication and prolonged PPI therapy,infiltrative gastric disorders such as HES should be considered.Tae Young Park Chang Hwan Choi Suh Yoon Yang InSoo Oh In-Do Song Hyun Woong Lee Hyung Joon Kim Jae Hyuk Do Sae Kyung Chang Ah Ra Cho Young Joo Cha 2009World Journal of Gastroenterology2009,15,48:2

8Anti-osteoarthritis effect of a combination treatment with human adipose tissue-derived mesenchymal stem cells and thrombospondin 2 in rabbits显示文摘BACKGROUND Osteoarthritis(OA),a chronic age-related disease characterized by the slowly progressive destruction of articular cartilage,is one of the leading causes of disability.As a new strategy for treatment of OA,mesenchymal stem cells(MSCs)have the potential for articular cartilage regeneration.Meanwhile,thrombospondin 2(TSP2)promotes the chondrogenic differentiation of MSCs.AIM To investigate whether TSP2 induces chondrogenic differentiation of human adipose-derived MSCs(hADMSCs)and potentiates the therapeutic effects of hADMSCs in OA rabbits.METHODS We investigated the chondrogenic potential of TSP2 in hADMSCs by analyzing the expression of chondrogenic markers as well as NOTCH signaling genes in normal and TSP2 small interfering RNA(siRNA)-treated stem cells.Anterior cruciate ligament transection surgery was performed in male New Zealand white rabbits,and 8 wk later,hADMSCs(1.7×10^6 or 1.7×10^7 cells)were injected into the injured knees alone or in combination with intra-articular injection of TSP2(100 ng/knee)at 2-d intervals.OA progression was monitored by gross,radiological,and histological examinations.RESULTS In hADMSC culture,treatment with TSP2 increased the expression of chondrogenic markers(SOX9 and collagen Ⅱ)as well as NOTCH signaling genes(JAGGED1 and NOTCH3),which were inhibited by TSP2 siRNA treatment.In vivo,OA rabbits treated with hADMSCs or TSP2 alone exhibited lower degree of cartilage degeneration,osteophyte formation,and extracellular matrix loss 8 wk after cell transplantation.Notably,such cartilage damage was further alleviated by the combination of hADMSCs and TSP2.In addition,synovial inflammatory cytokines,especially tumor-necrosis factor-α,markedly decreased following the combination treatment.CONCLUSION The results indicate that TSP2 enhances chondrogenic differentiation of hADMSCs via JAGGED1/NOTCH3 signaling,and that combination therapy with hADMSCs and TSP2 exerts synergistic effects in the cartilage regeneration of OA joints.Kyungha Shin Yeseul Cha Young-Hwan Ban Da Woom Seo Ehn-Kyoung Choi Dongsun Park Sung Keun Kang Jeong Chan Ra Yun-Bae Kim 2019World Journal of Stem Cells2019,11,12:2
