| 1 | 急性缺血性卒中静脉阿替普酶溶栓治疗的纳入和排除标准的科学依据美国心脏协会/美国卒中协会对医疗卫生专业人员发布的声明(续前)显示文摘19 颅内出血史
根据最初的 FDA 标签和2013年AHA/ASA指南,颅内出血史是静脉阿替普酶治疗缺血性卒中的一项额外禁忌证或排除标准。最近修订后的标签仅将近期 ICH 列为一项警告,并且在禁忌证中删除了ICH史。与前面讨论的静脉阿替普酶治疗排除标准相似,文献回顾仅在大样本回顾性研究中发现了少量这类病例。缺乏相关数据可能是修订后的FDA 标签不再将 ICH 史作为禁忌证而仅将近期ICH 列为一项警告的原因。在这种情况下,FDA 如何定义“近期”一词尚不清楚。有趣的是,对在静脉阿替普酶治疗前通过 MRI 检测脑微出血( cerebral microbleed, CMBs)存在情况进行的研究可为这个卒中亚组患者提供更多的见解。从病理生理学角度,这种微出血的原因尚不清楚,可能反映再灌注损伤或脑血管自动调节功能破坏。因此,在静脉阿替普酶治疗后出现这些损害可能没有意义或是人为信号。 | Dawn O.

| 2 | 气候变暖背景下青藏高原植被覆盖特征的时空变化及其成因分析显示文摘正交分解反演于NOAA-AVHRR数据的叶面积指数、空间特征场分布和时间系数变化显示,自20世纪80年代初至2000年,在全球变暖气候大背景下,青藏高原地区植被覆盖率总体上呈增加趋势.降水量与主特征场时间系数相关性分析表明,降水量是决定高原地区植被整体覆盖年际变化和波动的主要气候驱动因素.植被覆盖总体增加的同时,高原地区植被覆盖率也存在显著的南北反相位区域变化特征,气候变暖是造成植被覆盖南北反相位变化的主要原因.气温持续增高导致活动积温增加,有利于高原南缘湿润地区植被的生长,相反却使高原北部地区干旱加剧,不利于植被覆盖状况的改善. | 徐兴奎 陈红 LEVY JasonK | 2008 | 科学通报2008，53，4： | 67 |
| 3 | Spatiotemporal vegetation cover variations in the Qinghai-Tibet Plateau under global climate change显示文摘Empirical Orthogonal Function (EOF) analysis and the related Principal Components (PC) analysis are used to extract valuable vegetation cover derived information from the National Oceanic and Atmos- pheric Administration (NOAA-AVHRR)'s Leaf Area Index (LAI) satellite images. Results suggest that from 1982 to 2000 global climate change has contributed to an increase in vegetation cover in the Qinghai-Tibet Plateau. The correlation between rainfall and LAI EOF PC1 and PC2 indicates that rainfall is the major climatic factor influencing interannual variations of average vegetation cover throughout the entire Plateau. However, annual mean vegetation cover trends in the Qinghai-Tibet Plateau are mainly out of phase with air temperature increasing, which is primarily responsible for nonsynchro- nous changes of vegetation cover. In the southern ridge of the Qinghai-Tibet Plateau, recent warming trends contribute to humid weather and favorable conditions for vegetation growth. By contrast, higher temperatures have led to arid conditions and insufficient rainfall in the northern part of the Plateau, leading to drought and other climatic conditions which are not conducive to increased vegetation cover. | XU XingKui CHEN Hong Jason K LEVY | 2008 | Chinese Science Bulletin2008，53，6： | 28 |
| 4 | 经颅多普勒超声(TCD)的实践标准——第2部分:临床适应证和预期结果显示文摘引言:经颅多普勒(transcranial Doppler,TCD)已被证实为一种安全有效的生理学超声检查技术。尽管成像设备可以在结构影像的基础上显示颅内血流,但成像性双功能超声或非成像性TCD检查提供的最终结果是通过频谱波形来评价生理学血流参数。总结概要:多学科专家小组确定的TCD临床适应证包括:镰状细胞病、恼缺血、右向左分流(right—to—left shunt,RLS)、蛛网膜下腔出血、脑死亡以及围手术期或术中监测。TCD检查可常规应用于住院或门诊患者的一些临床实践活动:通过完整或部分TCD检查以检测正常、狭窄或闭塞的颅内血管和侧支循环来判断动脉闭塞位置,并进一步完善颈动脉超声或无创性血管造影结果;通过血管运动反应性检查来识别首发或复发性卒中的高危患者;通过栓子监测对脑栓塞进行实时检查、定位和量化;在怀疑反常性栓塞或考虑分流封堵术治疗的患者中进行RLS检测;对溶栓治疗进行监测以促进血管再通和检测再闭塞;在血管内支架置入术、颈动脉内膜切除术和心脏外科手术中进行监测以发现围手术期栓塞、血栓形成、低灌注或高灌注。结论:通过界定实践范围,这些标准将在TCD检查的申请、检查和评价过程中给开申请单的医生、发报告的医生以及第三方提供帮助。 | Andrei V.

| 7 | Fibrinogen-like protein 2 fibroleukin expression and its correlation with disease progression in murine hepatitis virus type 3-induced fulminant hepatitis and in patients with severe viral hepatitis B显示文摘AIM: To evaluate the expression of fibrinogenlike protein 2 (fgl2) and its correlation with disease progression in both mice and patients with severe viral hepatitis.METHODS: Balb/cJ or A/J mice were infected intraperitoneally (ip) with 100 PFU of murine hepatitis virus type 3 (MHV-3), liver and serum were harvested at 24, 48, and 72 h post infection for further use. Liver tissues were obtained from 23 patients with severe acute chronic (AOC) hepatitis B and 13 patients with mild chronic hepatitis B. Fourteen patients with mild chronic hepatitis B with cirrhosis and 4 liver donors served as normal controls. In addition, peripheral blood mononuclear cells (PBMC) were isolated from 30 patients (unpaired) with severe AOC hepatitis B and 10 healthy volunteers as controls. Procoagulant activity representing functional prothrombinaseactivity in PBMC and white blood cells was also assayed. A polyclonal antibody against fgl2 was used to detect the expression of both mouse and human fgl2 protein in liver samples as well as in PBMC by immunohistochemistry staining in a separate set of studies. Alanine aminotransferase (ALT) and total bilirubin (TBil) in serum were measured to assess the severity of liver injury.RESULTS: Histological changes were found in liver sections 12-24 h post MHV-3 infection in Balb/cJ mice.In association with changes in liver histology, marked elevations in serum ALT and TBil were observed. Mouse fgl2 (mfgl2) protein was detected in the endothelium of intrahepatic veins and hepatic sinusoids within the liver 24 h after MHV-3 infection. Liver tissues from the patients with severe AOC hepatitis B had classical pathological features of acute necroinflammation. Human fgl2 (hfgl2)was detected in 21 of 23 patients (91.30%)with severe AOC hepatitis B, while only 1 of 13 patients(7.69%) with mild chronic hepatitis B and cirrhosis had hfgl2 mRNA or protein expression. Twenty-eight of thirty patients (93.33%) with severe AOC hepatitis B and 1of 10 with mild chronic hepatitis B had detectable hfgl2expression in PBMC. No hfgl2 expression was found either in the liver tissue or in the PBMC from normal donors. There was a positive correlation between hfgl2expression and the severity of the liver disease as indicated by the levels of TBil. PCA significantly increased in PBMC in patients with severe AOC hepatitis B.CONCLUSION: The molecular and cellular results reported here in both mice and patients with severe viral hepatitis suggest that virus-induced hfgl2prothrombinase/fibroleukin expression and the coagulation activity associated with the encoded fgl2protein play a pivotal role in initiating severe hepatitis.The measurement of hfgl2/fibroleukin expression in PBMC may serve as a useful marker to monitor the severity of AOC hepatitis B and a target for therapeutic intervention. | Chuan-Long Zhu Wei-Ming Yan Fan Zhu Yong-Fen Zhu Dong Xi De-Ying Tian Gary Levy Xiao-Ping Luo Qin Ning | 2005 | World Journal of Gastroenterology2005，11，44： | 26 |

| 11 | Injection drug use and HIV/AIDS transmission in China显示文摘After nearly three decades of being virtually drug free, use of heroin and other illicit drugs has re-emerged in China as a major public health problem. One result is that drug abuse, particularly heroin injection, has come to play a predomi- nant role in fueling China’s AIDS epidemic. The first outbreak of HIV among China’s IDUs was reported in the border area of Yunnan province between China and Myanmar where drug trafficking is heavy. Since then drug-related HIV has spread to all 31 provinces, autonomous regions and municipalities. This paper provides an overview to HIV/AIDS transmission through injection drug use in China. It begins with a brief history of the illicit drug trade in China, followed by a discussion of the emergence of drug related AIDS, and a profile of drug users and their sexual partners who have contracted the virus or who are vulnerable to infection. It ends by summarizing three national strategies being used by China to address both drug use and AIDS as major health threats. | Tian Xin CHU Judith A LEVY | 2005 | Cell Research2005，15，11： | 17 |

| 15 | 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 |

| 19 | Stem Cell Ophthalmology Treatment Study (SCOTS): bone marrow-derived stem cells in the treatment of Leber's hereditary optic neuropathy显示文摘The Stem Cell Ophthalmology Treatment Study(SCOTS) is currently the largest-scale stem cell ophthalmology trial registered at Clinical Trials.gov(identifier: NCT01920867). SCOTS utilizes autologous bone marrow-derived stem cells(BMSCs) to treat optic nerve and retinal diseases. Treatment approaches include a combination of retrobulbar, subtenon, intravitreal, intra-optic nerve, subretinal, and intravenous injection of autologous BMSCs according to the nature of the disease, the degree of visual loss, and any risk factors related to the treatments. Patients with Leber's hereditary optic neuropathy had visual acuity gains on the Early Treatment Diabetic Retinopathy Study(ETDRS) of up to 35 letters and Snellen acuity improvements from hand motion to 20/200 and from counting fingers to 20/100. Visual field improvements were noted. Macular and optic nerve head nerve fiber layer typically thickened. No serious complications were seen. The increases in visual acuity obtained in our study were encouraging and suggest that the use of autologous BMSCs as provided in SCOTS for ophthalmologic mitochondrial diseases including Leber's hereditary optic neuropathy may be a viable treatment option. | Jeffrey N.

| 20 | Folic acid supplementation inhibits recurrence of colorectal adenomas:A randomized chemoprevention trial显示文摘AIM: To determine whether folic acid supplementation will reduce the recurrence of colorectal adenomas, the precursors of colorectal cancer, we performed a double-blind placebo-controlled trial in patients with adenomatous polyps. METHODS: In the current double-blind, placebo-controlled trial at this VA Medical Center, patients with colorectal adenomas were randomly assigned to receive either a daily 5 mg dose of folic acid or a matched identical placebo for 3 years. All polyps were removed at baseline colonoscopy and each patient had a follow up colonoscopy at 3 years. The primary endpoint was a reduction in the number of recurrent adenomas at 3 years. RESULTS: Of 137 subjects, who were eligible after confirmation of polyp histology and run-in period to conform compliance, 94 completed the study; 49 in folic acid group and 45 in placebo group. Recurrence of adenomas at 3-year was compared between the two groups. The mean number of recurrent polyps at 3-year was 0.36 (SD, 0.69) for folic acid treated patients compared to 0.82 (SD, 1.17) for placebo treated subjects, resulting in a 3-fold increase in polyp recurrence in the placebo group. Patients below 70 years of age and those with left-sided colonicadenomas or advanced adenomas responded better to folic acid supplementation. CONCLUSION: High dose folic acid supplementation is associated with a signif icant reduction in the recurrence of colonic adenomas suggesting that folic acid may be an effective chemopreventive agent for colorectal neoplasia. | Richard Jaszewski Sabeena Misra Martin Tobi Nadeem Ullah Jo Ann Naumoff Omer Kucuk Edi Levi Bradley N Axelrod Bhaumik B Patel Adhip PN Majumdar | 2008 | World Journal of Gastroenterology2008，14，28： | 10 |
