2正常人皮肤表面酸碱度的研究显示文摘皮肤是人类机体的重要组成部分.皮肤表面的酸碱度不仅是皮肤的生理指标.同时也反映了整个机体的状态。迄今为止,关于正常人皮肤表面pH值的报道不尽相同。据报道,婴儿出生时,皮肤表而的pH较高。数天后则逐渐降低。Wilhelm等曾对29例成人皮肤表面的pH进行了研究,结果发现,皮肤表而的pH囚皮肤解剖部位的不同而不同:老年人的前额和踝部皮肤表而的pH值高于年轻者。Zlotogorski的研究也证实了Wilhelm等的结果.但是也有报道,皮肤表面的pH因性别的差异而不同。这种差异性有多种因素,可能与研究组别的大小和分组的条件等有关。关于我国正常人皮肤表面pH的研究报道较少,笔者根据人体生长发育期的生理特点进行年龄分组;根据皮肤的生理特点进行部位分组。对我国正常人不同年龄、不同性别和不同部位的皮肤pH进行检测,为临床工作提供参考。辛淑君 刘之力 史月君 Kenneth R Feingold Peter M Elias 蔄茂强 2007临床皮肤科杂志2007,36,5:11
3Diabetes mellitus as a risk factor for gastrointestinal cancer among American veterans显示文摘AIM:To assess the risk of biliary and pancreatic cancers in a large cohort of patients with type 2 diabetes mellitus(DM) .METHODS:Eligibility for this study included patients with type 2 DM(ICD-9 code 250.0) who were discharged from Department of Veteran Affairs hospitals between 1990 and 2000.Non-matched control patients without DM were selected from the same patient treatment files during the same period.Demographic information included age,sex and race.Secondary diagnoses included known risk factors based on their ICD-9 codes.By multivariate logistic regression,the occurrence of biliary and pancreatic cancer was compared between case subjects with DM and controls without DM.RESULTS:A total of 1172496 case and control subjects were analyzed.The mean age for study and control subjects was 65.8 ± 11.3 and 64.8 ± 12.6 years,respectively.The frequency of pancreatic cancer in subjects with DM was increased(0.9%) in comparison to control subjects(0.3%) with an OR of 3.22(95% CI:3.03-3.42) .The incidence of gallbladder andextrahepatic biliary cancers was increased by twofold in diabetic patients when compared to controls.The OR and 95% CI were 2.20(1.56-3.00) and 2.10(1.61-2.53) ,respectively.CONCLUSION:Our study demonstrated that patients with DM have a threefold increased risk for developing pancreatic cancer and a twofold risk for developing biliary cancer.M Mazen Jamal Eugene J Yoon Kenneth J Vega Mehrtash Hashemzadeh Kenneth J Chang 2009World Journal of Gastroenterology2009,15,42:10

5Stem cell therapy for the treatment of Leydig cell dysfunction in primary hypogonadism显示文摘The production of testosterone occurs within the Leydig cells of the testes. When production fails at this level from either congenital, acquired, or systemic disorders,the result is primary hypogonadism. While numerous testosterone formulations have been developed, none are yet fully capable of replicating the physiological patterns of testosterone secretion. Multiple stem cell therapies to restore androgenic function of the testes are under investigation. Leydig cells derived from bone marrow, adipose tissue, umbilical cord, and the testes have shown promise for future therapy for primary hypogonadism. In particular, the discovery and utilization of a group of progenitor stem cells within the testes, known as stem Leydig cells(SLCs), has led not only to a better understanding of testicular development, but of treatment as well. When combining this with an understanding of the mechanisms that lead to Leydig cell dysfunction, researchers and physicians will be able to develop stem cell therapies that target the specific step in the steroidogenic process that is deficient. The current preclinical studies highlight the complex nature of regenerating this steroidogenic process and the problems remain unresolved. In summary, there appears to be two current directions for stem cell therapy in male primary hypogonadism. The first method involves differentiating adult Leydig cells from stem cells of various origins from bone marrow, adipose, or embryonic sources. The second method involves isolating, identifying, and transplanting stem Leydig cells into testicular tissue. Theoretically, in-vivo re-activation of SLCs in men with primary hypogonadism due to age would be another alternative method to treat hypogonadism while eliminating the need for transplantation.Taylor C Peak Nora M Haney William Wang Kenneth J DeLay Wayne J Hellstrom 2016World Journal of Stem Cells2016,8,10:5
6表皮通透屏障功能与表皮CD44表达关系的研究显示文摘目的:研究表皮通透屏障功能破坏后表皮CD44的表达。方法:外用胶带破坏裸鼠躯干部表皮通透屏障功能,分别于30min、1h、3h、6h、24h和48h后取皮肤标本,用免疫组化的方法观察CD44在表皮的表达。结果:在表皮通透屏障功能破坏后30min,表皮CD44的表达明显上调;1h和3h后,恢复至正常水平;6h后,表皮CD44的表达又明显增强,并持续到48h;人为地纠正屏障功能(封包)对表皮CD44的表达没有明显影响。结论:表皮通透屏障功能破坏后,表皮CD44的表达增强,其表达的改变与屏障功能本身无显著相关性。Mona Man 吕成志 辛淑君 Kenneth R Feingold Peter M Elias 蔄茂强 2008临床皮肤科杂志2008,37,7:5
7糖皮质激素对表皮功能的调节显示文摘糖皮质激素是临床上最常用的药物之一。它对表皮的发育、表皮屏障功能的形成、表皮脂代谢、角质层致密性、角质形成细胞的增生和分化均具有重要的调节作用。恰当地应用糖皮质激素能有利于治疗包括皮肤病在内某些疾病;使用不当可引起严重的不良反应。因此,很好地了解糖皮质激素对表皮功能的影响,对于指导临床合理应用糖皮质激素以及防治由其引起的不良反应具有重要意义。蔄茂强 宋顺鹏 Kenneth R.Feingold Peter M Elias 2009临床皮肤科杂志2009,38,12:4
8Comparison of reflux esophagitis and its complications between African Americans and non-Hispanic whites显示文摘AIM: To determine the effect of ethnicity on the severity of reflux esophagitis (RE) and its complications. METHODS: A retrospective search of the endoscopy database at the University of Florida Health Science Center/Jacksonville for all cases of reflux esophagitis and its complications from January 1 to March 31, 2001 was performed. Inclusion criteria were endoscopic evidence of esophagitis using the LA classif ication, reflux related complications and self-reported ethnicity. The data obtained included esophagitis grade, presence of a hiatal hernia, esophageal ulcer, stricture and Barrett's esophagus, and endoscopy indication. RESULTS: The search identified 259 patients with RE or its complications, of which 171 were non-Hispanic whites and 88 were African Americans. The mean ages and male/female ratios were similar in the two groups. RE grade, esophageal ulcer, stricture and hiatal hernia frequency were likewise similar in the groups. Barrett's esophagus was present more often in non-Hispanic whites than in African Americans (15.8% vs 4.5%; P < 0.01). Heartburn was a more frequent indication for endoscopy in non-Hispanic whites with erosive esophagitis than in African Americans (28.1% vs 7.9%; P < 0.001). CONCLUSION: Distribution of RE grade and frequency of reflux-related esophageal ulcer, stricture andhiatal hernia are similar in non-Hispanic whites and African Americans. Heartburn was more frequently and nausea/vomiting less frequently reported as the primary endoscopic indication in non-Hispanic whites compared with African Americans with erosive esophagitis or its complications. African Americans have a decreased prevalence of Barrett's esophagus compared with non-Hispanic whites.Kenneth J Vega Sian Chisholm M Mazen Jamal 2009World Journal of Gastroenterology2009,15,23:4

13老年人与交通事故的调查分析(英文)显示文摘目的中国目前正在经历老年人口与交通车辆的同时快速增长。随着人口的老龄化加剧以及社会的发展,老年驾驶者人数将预期明显增加。国际上对老年人交通安全的经验可能对中国即将增加的老年驾驶者有借鉴作用。方法检索并分析了中国以及一些发达国家,如美国等有关老年驾驶者以及交通事故安全的论文及论著。结果尽管老年人较少开车且普遍地使用安全带,但他们交通事故发生数以及死亡率较其他年龄组高。老年人视觉以及感知功能的损害也增加了发生交通事故的危险性,同时也产生了其独特的事故形式。与年轻人相比,在相同的受伤程度下,老年人体格上的衰退和疾病因素可能对会产生更坏的结果。虽然老年驾驶者在中国还是少数,与其他年龄组相比,老年人有较高的交通事故伤害率、步行者死亡率和较高的农村老年人受害率。结论国际上对老年人交通安全的经验,比如更好的道路安全设计,高可视安全标识和安全带法律的实施,安全带使用的公共教育,以及老年驾驶证的更新等对中国的交通安全设计者以及法律的制定者可能会有帮助。这些经验对损伤预防研究者在老年人交通事故危险因素的识别方面,以及对工程师在驾驶环境和车辆设计等方面也有着重要的意义。HENG Kenneth PAN Shuming LAYDE M Peter ZHU Shankuan 2006中华急诊医学杂志2006,15,1:3

19Assessment of the diagnostic performance and interobserver variability of endocytoscopy in Barrett's esophagus:A pilot ex-vivo study显示文摘AIM:To investigate a classification of endocytoscopy(ECS)images in Barrett’s esophagus(BE)and evaluate its diagnostic performance and interobserver variability.METHODS:ECS was applied to surveillance endoscopic mucosal resection(EMR)specimens of BE ex-vivo.The mucosal surface of specimen was stained with 1%methylene blue and surveyed with a catheter-type endocytoscope.We selected still images that were most representative of the endoscopically suspect lesion and matched with the final histopathological diagnosis to accomplish accurate correlation.The diagnostic performance and inter-observer variability of the new classification scheme were assessed in a blinded fashion by physicians with expertise in both BE and ECS and inexperienced physicians with no prior exposure to ECS.RESULTS:Three staff physicians and 22 gastroenterology fellows classified eight randomly assigned unknown still ECS pictures(two images per each classification)into one of four histopathologic categories as follows:(1)BEC1-squamous epithelium;(2)BEC2-BE without dysplasia;(3)BEC3-BE with dysplasia;and(4)BEC4-esophageal adenocarcinoma(EAC)in BE.Accuracy of diagnosis in staff physicians and clinical fellows were,respectively,100%and 99.4%for BEC1,95.8%and83.0%for BEC2,91.7%and 83.0%for BEC3,and95.8%and 98.3%for BEC4.Interobserver agreement of the faculty physicians and fellows in classifying each category were 0.932 and 0.897,respectively.CONCLUSION:This is the first study to investigate classification system of ECS in BE.This ex-vivo pilot study demonstrated acceptable diagnostic accuracy and excellent interobserver agreement.Yutaka Tomizawa Prasad G Iyer Louis M Wongkeesong Navtej S Buttar Lori S Lutzke Tsung-Teh Wu Kenneth K Wang 2013World Journal of Gastroenterology2013,19,46:2
20Evolution of endovascular mechanical thrombectomy for acute ischemic stroke显示文摘Acute ischemic stroke(AIS) is a common medical problem associated with significant morbidity and mortality worldwide. A small proportion of AIS patients meet eligibility criteria for intravenous thrombolysis(IVT) with recombinant tissue plasminogen activator, and its efficacy for large vessel occlusion is poor. Therefore, an increasing number of patients with AIS are being treated with endovascular mechanical thrombectomy when IVT is ineffective or contraindicated. Rapid advancement in catheter-based and endovascular device technology has led to significant improvements in rates of cerebral reperfusion with these devices. Stentrievers and modern aspiration catheters have now surpassed earlier generation devices in the degree and rapidity of revascularization. This progress has been achieved with no concurrent increase in risk of major complications or mortality, both when used alone or in combination with IVT. The initial randomized controlled trials comparing endovascular therapy to IVT for AIS failed to show superior outcomes with endovascular treatment, butkey limitations of each trial may limit the significance of these results to current practice. While endovascular devices and operator experience continue to evolve, we are optimistic that this will be accompanied by improvements in patient outcomes. This review highlights the major endovascular devices used in current practice and the trials which have investigated their efficacy.Colin J Przybylowski Dale Ding Robert M Starke Christopher R Durst R Webster Crowley Kenneth C Liu 2014World Journal of Clinical Cases2014,2,11:2
