4食管鳞状细胞癌基因组改变的确认显示文摘食管癌是最具侵袭性的癌症之一,居全球恶性肿瘤病死率的第六位。全球约70%的食管癌患者在中国,食管鳞状细胞癌是最常见的病理类型(〉90%)。目前,临床上对于食管鳞状细胞癌的早期诊断和治疗非常有限,患者5年生存率仅为10%。然而,直到目前对于导致食管鳞状细胞癌发病的完整基因组事件仍知之甚少。本组对158例食管鳞状细胞癌病例进行一次全面的基因组分析:其中17例食管鳞状细胞癌病例进行全基因组测序,71例进行外显子测序,Song Y Li L Ou Y 崔淼 许春伟 张博 2014临床与实验病理学杂志2014,30,11:129
5激光剥蚀信号在线平滑和去汞装置:原位微区铅同位素准确分析利器显示文摘激光原位微区分析可在微观尺度上完成样品的元素定量分析或同位素组成测定,为研究成岩、成矿物质来源和追踪地壳与地幔演化历史提供了独特的观察视野。但是,激光剥蚀等离子体质谱的一些缺陷阻碍了地质样品的高精度、高空间分辨率分析,比如:剥蚀池的位置效应、低剥蚀速率下信号波动影响、激光剥蚀脉动式信号导致的光谱螺纹效应、高频激光剥蚀造成的元素分馏效应等。为此,一些学者设计了不同规格和样式的激光剥蚀信号平滑装置来克服这些问题。但是,这些信号平滑装置普遍还存在气体吹扫时间过长和降低激光剥蚀信号灵敏度等问题。因此,研制新型的信号平滑装置对改善LA—ICP—MS的数据质量具有重要的意义。Hu Z Zhang W Liu Y Gao S Li M Zong K Chen H Hu S 刘勇胜 2015矿物岩石地球化学通报2015,34,4:114
6进展期胃癌行腹腔镜与开腹D2远端胃癌根治术的并发症发生率和死亡率的随机对照研究显示文摘目的腹腔镜根治性远端胃切除(radical laparoscopic distal gastrectomy,LG)+D2淋巴结清扫术用于治疗进展期胃癌其安全性和有效性仍存在争议。本研究设计了一个前瞻性随机对照研究来对比腹腔镜手术和传统开腹手术行根治性远端胃切除术+D2淋巴结清扫术在治疗进展期胃癌的安全性和疗效。研究对象和方法自2012年9月至2014年12月,1056例临床分期为T(2-4a)N0-3M0的胃癌患者被纳入本研究。患者被随机分为腹腔镜根治性远端胃切除术+D2淋巴清扫组(LG组)(n=528)和开腹远端胃切除术(open gastrectomy,OG)+D2淋巴清扫组(OG组)(n=528)。共有15位来自中国14个研究中心的经验丰富的外科医生参与此次研究。根据意向性治疗分析原则比较LG组(n=519)和OG组(n=520)手术后30天内的并发症发生率和死亡率。术后并发症严重程度分级根据Clavien-Dindo分级方法。结果 LG组和OG组患者的D2淋巴结清扫术的合格率相似(99.4%vs.99.6%;P=0.845)。术后并发症发生率在LG组为15.2%,OG组为12.9%,统计学无明显差异(相差2.3%,95%CI:-1.9-6.6,P=0.285)。死亡率在LG组为0.4%,而OG组无一例死亡(相差0.4%,95%CI:-0.4-1.4,P=0.249)。两组并发症的严重程度分布相似(P=0.314)。结论有经验的外科医生可以在进展期胃癌患者上安全开展腹腔镜下根治性远端胃切除术+D2淋巴结清扫。Hu Y Huang C Sun Y 戴伟钢 2016消化肿瘤杂志(电子版)2016,8,3:202

9Type 2 diabetes mellitus and CA 19-9 levels显示文摘AIM:To prospectively investigate serum CA 19-9 levels in type 2 diabetic patients in comparison with age-and gender-matched control subjects. METHODS:We recorded duration of diabetes and examined fasting glucose levels,HbA1c levels and serum CA 19-9 levels in 76 type 2 diabetic patients and 76 controls.Abdominal CT was performed in order to eliminate abdominal malignancy in the diabetic and control groups. RESULTS:The average CA 19-9 level was 46.0±22.4 U/mL for diabetic patients whereas it was 9.97±7.1 U/mL for the control group(P<0.001).Regression analysis showed a positive correlation between diabetes and CA 19-9 independent from age,gender,glucose level and HbA1c level(t=8.8,P<001).Two of the diabetic patients were excluded from the study because of abdominal malignancy shown by CT at the initial evaluation.For all patients,abdominal CT showed no pancreatic abnormalities. CONCLUSION:CA 19-9 is a tumor-associated antigen, which is elevated in pancreatic,upper gastrointestinal tract,ovarian hepatocellular,and colorectal cancers,as well as in inflammatory conditions of the hepatobiliary system,biliary obstruction and in thyroid diseases. Diabetes has been claimed to be a risk factor for pancreatic cancer,which is increasing its incidence and has one of the lowest survival rates of all cancers.CA 19-9 is used in the diagnosis of pancreatic cancer but is also a marker of pancreatic tissue damage that might be caused by diabetes.We propose that a higher cut- off value of CA 19-9 should be used in diabetics to differentiate benign and malignant pancreatic disease, and subtle elevations of CA 19-9 in diabetics should be considered as the indication of exocrine pancreatic dysfunction.Oya Uygur-Bayramicli Resat Dabak Ekrem Orbay Can Dolapclo■lu Mehmet Sargin Gamze Kilico■lu Yüksel Güleryüzlü Alpaslan Mayada■li 2007World Journal of Gastroenterology2007,13,40:63
10二氢乳清酸脱氢酶介导的铁死亡防御是肿瘤治疗中的潜在靶点显示文摘铁死亡是一种过度的脂质过氧化诱导的调节性细胞死亡形式,是关键的肿瘤抑制机制。谷胱甘肽过氧化物酶4(GPX4)和铁死亡抑制蛋白1(FSP1)构成了2个主要的铁死亡防御系统。本研究表明用GPX4抑制剂治疗癌细胞会导致N-氨基甲酰基-l-天冬氨酸(一种嘧啶生物合成中间体)的急性消耗,并伴随尿苷的积累。李娜(编译) Mao C Liu X Zhang Y 2021国际老年医学杂志2021,42,4:69
11金厂沟梁-二道沟金矿田内花岗岩类侵入体锆石的离子探针U-Pb年代学及意义显示文摘金厂沟梁-二道沟金矿田内花岗岩类侵入体SHRIMP锆石U-Ph定年结果表明,该区中生代以来到少经历了三次中酸性岩浆侵入作用,它们分别以西台子二长花岗岩、娄上含辉石石英闪长岩和西对面沟花岗闪长岩及闪长玢岩脉在218±4Ma(印支期)、161±1Ma(燕山早期)和126±1Ma(燕山晚期)的侵位为标志。花岗岩类的地球化学资料表明,这些花岗岩类侵入体形成与造山作用有关,为造山后或陆内拉张作用的产物。二道沟矿区成矿前或成矿期闪长玢岩脉的年龄126±1Ma限定了该区金矿化的最大年龄;结合前人有关年代学资料,认为本区金矿化应发生在126~118Ma。这说明金厂沟梁-二道沟金矿田的金矿床与我国胶东、小秦岭和辽东等地区的金矿床是同时形成的,再次证明燕山晚期是中国最重要而广泛的金成矿期。此外,在这些主要的金矿区内,金矿化时间上均具有与各自区内最晚一次花岗质岩浆作用同时或稍晚的特征,这可能指示金矿床是造山作用或区域构造-岩浆演化最晚期的产物。苗来成 范蔚茗 翟明国 Qiu Y M McNaughton N J Groves D I 2003岩石学报2003,19,1:70
12Viral and host causes of fatty liver in chronic hepatitis B显示文摘AIM: To investigate the viral and host causes of fatty liver in chronic hepatitis B patients and the role of fat deposits in liver damage.METHODS: A total of 164 patients (113 males and 51 females, average age 35±11.3 years, and range 10-62 years) with previously untreated chronic hepatitis B were included in the study. The patients were divided into two groups depending on the result of liver biopsy: group without steatosis (100 patients with <5% hepatosteatosis) and group with steatosis (64 patients with >5% hepatosteatosis). The groups were compared in terms of gender, body mass index (BMI), liver enzymes (ALT, AST, ALP, GGT), cholesterol, triglyceride, HBeAg, viral load, and histological findings. In the group with steatosis, the patients were subdivided depending on the degree of steatosis into mild group (45 patients with 5-24% steatosis), and severe group (19 patients with >25% steatosis). RESULTS: In the group of chronic hepatitis B with steatosis, the mean age, BMI, cholesterol, and triglyceride levels were significantly higher than those in the group without steatosis (P<0.05). Steatosis was found in 53 (46.9%) of male patients and 11 (22%) of female patients (P<0.05). No significant difference was found in the positivity of ALT, AST, ALP, GGT, HBeAg, viral load, histological activity index (HAI) and stage between the two groups (P>0.05). In the group with severe steatosis, the BMI was significantly higher than that in the group with mild steatosis (P<0.05). No significant difference was found in the other parameters between the groups (P>0.05). CONCLUSION: Steatosis in chronic hepatitis B appears to be a result of metabolic factors of the host rather than the effect of viruses. Steatosis is unrelated to the HAI and degree of fibrosis, which are considered as the histological indicators of liver damage.Emin Altiparmak Seyfettin K(o|¨)klü Mesut Yalinkilic Osman Yüksel Bahattin Cicek Ertugrul Kayacetin Tülin Sahin 2005World Journal of Gastroenterology2005,11,20:52

16WONCA研究论文摘要汇编——急性颅内出血后血压变异性及转归:INTERACT2研究的析因分析,一项随机对照试验显示文摘背景高血压是急性脑卒中的预后因子,血压变异性或许可以独立预测脑卒中的转归。我们评估了血压变异性对INTERACT2参试者脑卒中预后的预测价值, INTERACT2是一项开放标签随机对照试验。方法 INTERACT2将患有自发性颅内出血(ICH)、高收缩压(150~220 mm Hg)、对早期降压强化疗法无明确适应证或禁忌证的2839例成人纳入研究。将患者随机分为强化治疗组(经静脉给药,1 h内目标收缩压降至<140 mm Hg )和指南推荐的治疗组( ICH 后6 h 内,目标收缩压降至<180 mm Hg)。主要转归为死亡或90 d内发生生活大部分无法自理(改良Rankin量表评分≥3分);次要转归为90 d内改良Rankin量表评分发生顺序移动,调查员在评分时并不知晓患者接受了哪种治疗。根据标准定义血压变异性:在发病头24 h (超急性期)进行5次测量,在发病后2~7 d (急性期)进行不少于12次的测量。采用比例优势逻辑回归模型评价血压变异性与转归之间的关联。血压变异性关键指标为收缩压的标准差,按五分位数加以分类。发现研究者对2645例(93.2%)处于超急性期的患者和2347例(82.7%)处于急性期的患者进行了调查。将两个治疗组的数据一起分析,在超急性期〔最高五分位数校正OR=1.41,95%CI (1.05,1.90); P=0.0167〕和急性期〔最高五分位数校正OR=1.57,95%CI (1.14,2.17); P=0.0124〕,收缩压的标准差与主要转归均呈线性相关。对转归最强的预测指标为超急性期最高收缩压和急性期收缩压的标准差为结果的最强预示因子。对次要转归进行分析,得到的结果与以上结果相似〔超急性期最高五分位数,校正OR=1.43,95%CI (1.14,1.80); P=0.0014;急性期OR=1.46,95%CI (1.13,1.88); P=0.0044〕。解释收缩压变异性似乎可预测急性颅内出血患者的不良转归。早期治疗将收缩压降至140 mm Hg以下获得的收益,可通过平稳并持续血压控制进行强化,避免出现收缩压峰值尤为重要。Manning L Hirakawa Y Arima H 周淑新 2014中国全科医学2014,17,21:56
17History of Helicobacter pylori,duodenal ulcer,gastric ulcer and gastric cancer显示文摘Helicobacter pylori(H.pylori)infection underlies gastric ulcer disease,gastric cancer and duodenal ulcer disease.The disease expression reflects the pattern and extent of gastritis/gastric atrophy(i.e.,duodenal ulcer with non-atrophic and gastric ulcer and gastric cancer with atrophic gastritis).Gastric and duodenal ulcers and gastric cancer have been known for thousands of years.Ulcers are generally non-fatal and until the 20th century were difficult to diagnose.However,the presence and pattern of gastritis in past civilizations can be deduced based on the diseases present.It has been suggested that gastric ulcer and duodenal ulcer both arose or became more frequent in Europe in the 19th century.Here,we show that gastric cancer and gastric ulcer were present throughout the 17th to 19th centuries consistent with atrophic gastritis being the predominant pattern,as it proved to be when it could be examined directly in the late 19th century.The environment before the 20th century favored acquisition of H.pylori infection and atrophic gastritis(e.g.,poor sanitation and standards of living,seasonal diets poor in fresh fruits and vegetables,especially in winter,vitamin deficiencies,and frequent febrile infections in childhood).The latter part of the 19th century saw improvements in standards of living,sanitation,and diets with a corresponding decrease in rate of development of atrophic gastritis allowing duodenal ulcers to become more prominent.In the early 20th century physician’s believed they could diagnose ulcers clinically and that the diagnosis required hospitalization for'surgical disease'or for'Sippy'diets.We show that while H.pylori remained common and virulent in Europe and the United States,environmental changes resulted in changes of the pattern of gastritis producing a change in the manifestations of H.pylori infections and subsequently to a rapid decline in transmission and a rapid decline in all H.pylori-related diseases.David Y Graham 2014World Journal of Gastroenterology2014,20,18:52
