2Batroxobin reduces intracellular calcium concentration and inhibits proliferation of vascular smooth muscle cells显示文摘Background Batroxobin (BX),a serine protease used in defibrinogenation and thrombolysis,also has an effect on c-fos gene and growth factor. This study attempted to determine the effects of BX on the proliferation of vascular smooth muscle cells (VSMCs) and calcium metabolism. Methods VSMCs were treated with BX at concentrations of 0.1,0.3,or 1.0 mmol/L and cell numbers were determined at 0,24,48,and 72 hours. Intracellular calcium concentration ([Ca 2+ ]_i) was measured using direct fluorescence methods. Results BX was found to suppress proliferation of VSMCs in a dose-dependent fashion with inhibition rates of 18% and 31% by 48 and 72 hours,respectively. In addition,BX decreases basal [Ca 2+ ]_i significantly. The basal level in untreated cells was 162.7±33.8 nmol/L,and decreased to 131.5±27.7 nmol/L,128.3±28.5 nmol/L,and 125.6±34.3 nmol/L with the three concentrations of BX,respectively. Noradrenaline (NE)-induced [Ca 2+ ]_i stimulation was also attenuated by BX (0.1 mmol/L BX,20%±8% inhibition; 0.3 mmol/L BX,54%±11% inhibition; 1.0 mmol/L BX,62%±15% inhibition). The ability of NE to stimulate [Ca 2+ ]_i was attenuated in cultures in Ca 2+ -free medium,as was the ability of BX to blunt NE-induced stimulation. Conclusion These findings demonstrate that BX can effectively inhibit proliferation of VSMCs,probably by blocking the release and uptake of Ca 2+ ,thus influencing [Ca 2+ ]_i.宋清斌 魏敏杰 段志泉 张海强 LB Schwartz 辛世杰 2004Chinese Medical Journal2004,,6:25

5Current management of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC)is the sixth most common cancer worldwide and leading cause of death among patients with cirrhosis.Treatment guidelines are based according to the Barcelona Clinic Liver Cancer staging system.The choice among therapeutic options that include liver resection,liver transplantation,locoregional,and systemic treatments must be individualized for each patient.The aim of this paper is to review the outcomes that can be achieved in the treatment of HCC with the heterogeneous therapeutic options currently available in clinical practice.Parissa Tabrizian Sasan Roayaie Myron E Schwartz 2014World Journal of Gastroenterology2014,20,30:18
6人类血压测量方法:美国心脏协会科学声明显示文摘准确的血压测量对高血压诊断与治疗至关重要。该文是美国心脏协会关于人类血压测量的最新科学声明。业已证实,在诊室许多电子血压计可以准确测量血压,同时减少与听诊法有关的人为误差。即使没有一个观察者在场,全自动电子血压计也可以通过多次测量提供较听诊法更准确的血压测量值。研究表明诊室外所测血压与诊室血压比较存在实质性差别。目前认为动态血压监测是诊室外血压评估的参考标准,当动态血压监测不可行或患者不能耐受时,家庭血压监测则是一个替代方法。赵狄(摘译) 练桂丽(审校) Muntner P Shimbo D Carey RM Charleston JB Gaillard T Misra S Myers MG Ogedegbe G Schwartz JE Townsend RR Urbina EM Viera AJ White WB Wright JT Jr 2019中华高血压杂志2019,27,6:16
7Adenoid cystic carcinoma of breast: Recent advances显示文摘Adenoid cystic carcinoma(ACC) of the breast is a rare special subtype of breast cancer characterized by the presence of a dual cell population of luminal and basaloid cells arranged in specific growth patterns. Most breast cancers with triple-negative, basal-like breast features(i.e., tumors that are devoid of estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 expression, and express basal cell markers) are generally high-grade tumors with an aggressive clinical course. Conversely, while ACCs also display a triple-negative, basal-like phenotype, they are usually low-grade and exhibit an indolent clinical behavior. Many discoveries regarding the molecular and genetic features of the ACC, including a specific chromosomal translocation t(6;9) that results in a MYB-NFIB fusion gene, have been made in recent years. This comprehensive review provides our experience with ACC of the breast, as well as an overview of clinical, histopathological, and molecular genetic features.Kosuke Miyai Mary R Schwartz Mukul K Divatia Rose C Anton Yong Wook Park Alberto G Ayala Jae Y Ro 2014World Journal of Clinical Cases2014,2,12:16
8The Formation of Anthocyanic Vacuolar Inclusions in Arabidopsis thaliana and Implications for the Sequestration of Anthocyanin Pigments显示文摘Anthocyanins 是在大多数植物的大中央液泡积累的 flavonoid 颜料。在液泡内, anthocyanins 能被发现一致地分布式或作为 sub-vacuolar 颜料身体的部分, Anthocyanic Vacuolar 包括(AVI ) 。用作为一个模型在 anthocyanin 引入的条件下面变得理解 AVI 怎么被形成的 Arabidopsis 幼苗,我们这里证明 AVI 的累积强烈与 cyanidin 3 配糖物(C3G ) 和衍生物的形成相关。在 5-O 位置(5gt 异种) 失败到 glycosylate anthocyanidins 的 Arabidopsis 异种积累 AVI 在几乎子叶的每个表皮的房间作为与野类型的幼苗相比,在的地方仅仅房间表演 AVI 的小部分。当幼苗与 vanadate 被对待时,类似的现象被观察。在 AVI 的形成为 autophagy 加亮一个角色,我们证明防碍 autophagic 过程(atg 异种) 的各种各样的异种显示 AVI 的更低的数字,除了 anthocyanins 的减少的累积。有趣地, vanadate 在 atg 异种增加 AVI 的数字,建议几条小径可能参予 AVI 形成。一起拿,我们的结果为能够积累 anthocyanin 颜料的 sub-vacuolar 分隔空间的形成建议新奇机制。Lucille Pourcel Niloufer G.

10Selection of appropriate organic additives for enhancing Zn and Cd phytoextraction by hyperaccumulators显示文摘Chelant-enhanced phytoextraction is one of the most promising technologies to remove heavy metals from soil. The key of the technology is to choose suitable additives in combination with a suitable plant. In the present study, laboratory batch experiment of metal solubilization, cress seeds germination were undertaken to investigate the metal-mobilizing capability and the phytotoxicity of organic additives, including ethylene diamine triacetic acid (EDTA), citric acid, acetic acid, oxalic acid, glutamine and monosodium glutamate waste liquid (MGWL) from food industry. Experiments in pots were carried out to study the effects of the additives on Zn and Cd phytoextraction. Furthermore, a leaching experiment with lysimeter was performed to evaluate the environmental risks of additive-induced leaching to underground water. The results showed that EDTA had a strong mobilizing ability for Zn and Cd, followed by mixed reagent (MR) and MGWL. MGWL and acetic acid at 5 mmol equivalent per liter resulted in seed germination index less than 2%. Experiments in pots verified the phytotoxicity of acetic acid and MGWL. Addition of the mixed reagent at 6—10 mmol/kg significantly increased Zn phytoextraction by Thlaspi caerulescens. The same for EDTA and the mixed reagent at 10 mmol/kg by Sedum alfredii. But only mixed reagents could significantly increase Cd phytoextraction by the studied hyperaccumulators. This suggested that the strong chelant was not always the good agent to enhance phytoextraction. S. alfredii combined with 2—10 mmol/kg soil MR was preferred for phytoremediation of Cd/Zn contaminated soils in southern China, this could result in high phytoextraction of Cd/Zn and reduce the leaching risk to underground water than EDTA assisted phytoextration.WU Qi-tang DENG Jin-chuan LONG Xin-xian MOREL Jean-louis SCHWARTZ Christophe 2006Journal of Environmental Sciences2006,18,6:13
11Effect of vildagliptin as add-on therapy to a low-dose metformin显示文摘AIM:To evaluate the efficacy and safety of the addition of vildagliptin to low-dose metformin and compare it to an uptitration of metformin in type 2 diabetes mellitus(T2DM) patients who have inadequate control with metformin monotherapy.METHODS:Eligible patients were randomized to receive vildagliptin 100 mg qd or metformin(500 mg qd for 2 wk and then 500 mg bid) added to open label me tformin 500 mg bid for the 24 wk.The primary endpoi nt was baseline to endpoint hemoglobin A1c(HbA1c) change.RESULTS:The adjusted mean change from baseline in HbA1c at the 24th wk was-0.51% in the vildagliptin/metformin group(mean baseline HbA1c:7.4%) and-0.37% in the metformin monothera py group(mean baseline HbA1c:7.3%).The mean diffe rence was-0.14% with 95% Confidence Interval(-0.24%,-0.05%).As non-inf e riority(margin of 0.4%) was achieved,a test for superiority was performed.This test showed statistically significant superiority of the combination over monotherapy group(P = 0.002).Gastrointestinal(GI) adverse events were signif icantly more frequent in the metformin group than the combin ation group(21.0% vs 15.4%,P = 0.032).CONCLUSION:In patients with T2DM inadequately controlled with metformin up to 1000 mg daily,the addition of vildagliptin 100 mg daily achieved larger HbA1c reduction with fewer GI events than with increa sing the metformin dose.Claudia Filozof Sherwyn Schwartz James E Foley 2010World Journal of Diabetes2010,1,1:8
12Molecular dynamics simulation of ion selectivity traits of nickel hexacyanoferrate thin films显示文摘The ion selectivity of nickel hexacyanoferrate thin film to alkali cations in ESIX (electrochemically switched ion exchange) processes was investigated using molecular dynamics(MD) techniques; water and cation (Na+ and Cs+) intercalation, configuration, and dynamics in reduced nickel hexacyanoferrate structures with different cation combinations were studied and compared with the experimental results. In the simulations, water was represented by an extended simple point-charge(SPC/E) model, and all other atomic interactions were represented by a universal force field(UFF). The potential energies of various cations combination (Cs+ and Na+) in reduced i-NiHCF and 1 mol/L Cs/NaCl mixed solution were obtained. In most cases, the total potential energy of the solid is reduced when water is intercalated into the various reduced NiHCF structures. Combining the solid and the solution simulation results, it is shown that the solid composition of 3Cs+/1Na+ is the stablest structure form (NaCs3Ni4[Fe(CN)6]3) over a range of solution compositions.郝晓刚 YU Qiu-ming JIANG Shao-yi D.

13大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini 2021英国医学杂志中文版2021,24,8:7
14Prognosis of lymphotropic invasive micropapillary breast carcinoma analyzed by using data from the National Cancer Database显示文摘Background:Invasive micropapillary carcinoma(IMPC)is an uncommon subtype of breast cancer.Previous studies of this subtype demonstrated a higher propensity for lymph node metastases as compared with invasive ductal carci-noma(IDC).The purpose of the present study was to determine the clinical characteristics,outcomes,and propensity for lymph node metastasis of patients with IMPC of the breast recorded in the National Cancer Database(NCDB).Methods:Records of patients with IMPC diagnosed between 2004 and 2014 were retrieved from the NCDB.Log-rank test was performed to evaluate associations of clinical characteristics with overall survival(OS).Cox proportional hazards model was used to determine variables associated with OS.Results:Overall,2660 patients with IMPC met the selection criteria;the 5-year OS rate was 87.5%and 24.9%of patients had nodal involvement at presentation.Patients with≥4 positive lymph nodes had shorter OS than node-negative patients,whereas patients with 1-3 positive nodes had similar OS to node-negative patients.Age<65 years,receipt of radiotherapy,and estrogen receptor positivity were also associated with prolonged OS.The benefit of radiotherapy was limited to IMPC patients undergoing lumpectomy;there was no benefit for the patients undergoing mastectomy(regardless of nodal positivity/negativity).Conclusions:Favorable prognostic factors of IMPC patients included age<65 years,<4 positive lymph nodes,receipt of radiotherapy,and estrogen receptor positivity.The results presented herein suggest a survival benefit asso-ciated with radiotherapy in IMPC treatment,though this may be limited to the patients treated with lumpectomy.Gary D.Lewis Yan Xing Waqar Haque Tejal Patel Mary Schwartz Albert Chen Andrew Farach Sandra S.Hatch E.Brian Butler Jenny Chang Bin S.Teh 2019Cancer Communications2019,39,1:7

16Emerging treatments for complex perianal fistula in Crohn's disease显示文摘Complex perianal fistulas have a negative impact on the quality of life of sufferers and should be treated.Correct diagnosis,characterization and classification of the fistulas are essential to optimize treatment.Nevertheless, in the case of patients whose fistulas are associated with Crohn's disease,complete closure is particularly difficult to achieve.Systemic medical treatments(antibiotics, thiopurines and other immunomodulatory agents,and, more recently,anti-tumor necrosis factor-αagents such as infliximab)have been tried with varying degrees of success.Combined medical(including infliximab)and less aggressive surgical therapy(drainage and seton placement)offer the best outcomes in complex Crohn's fistulas while more aggressive surgical procedures such as fistulotomy or fistulectomy may increase the risk of incontinence.This review will focus on emerging novel treatments for perianal disease in Crohn's patients. These include locally applied infliximab or tacrolimus, fistula plugs,instillation of fibrin glue and the use of adult expanded adipose-derived stem cell injection.More welldesigned controlled studies are required to confirm the effectiveness of these emerging treatments.Carlos Taxonera David A Schwartz Damián García-Olmo 2009World Journal of Gastroenterology2009,15,34:6

18Endoscopic and non-endoscopic approaches for the management of radiation-induced rectal bleeding显示文摘Pelvic radiation is a commonly utilized treatment for malignancy of the genitourinary and lower gastrointestinal tract. Radiation proctitis and the resultant clinical picture varies from asymptomatic to potentially life threatening. Similarly, treatment options also vary greatly, from medical therapy to surgical intervention. Commonly utilized medical therapy includes sucralfate enemas, antibiotics, 5-aminosalicylic acid derivatives, probiotics, antioxidants, short-chain fatty acids, formalin instillation and fractionated hyperbaric oxygen. More invasive treatments include endoscopic-based, focally ablative interventions such as dilation, heater and bipolar cautery, neodymium/yttrium aluminum garnet argon laser, radiofrequency ablation or argon plasma coagulation. Despite its relatively common frequency, there is a dearth of existing literature reporting headto-head comparisons of the various treatment options via a randomized controlled approach. The purpose of our review was to present the reader a consolidation of the existing evidence-based literature with the goal of highlighting the comparative effectiveness and risks of the various treatment approaches. Finally, we outline a pragmatic approach to the treatment of radiation proctitis. In light of the lack of randomized data, our goal is to pursue as least invasive an approach as possible, with escalation of care tailored to the severity of the patient's symptoms. For those cases that are clinicallyasymptomatic or only mildly symptomatic, observation or medical management can be considered. Once a patient fails such management or symptoms become more severe, invasive procedures such as endoscopically based focal ablation or surgical intervention can be considered. Although not all recommendations are supported by level I evidence, reported case series and single-institutional studies in the literature suggest that successful treatment with cessation of symptoms can be obtained in the majority of cases.Joseph Paul Weiner Andrew Thomas Wong David Schwartz Manuel Martinez Ayse Aytaman David Schreiber 2016World Journal of Gastroenterology2016,22,31:5
19肝的周期性的巨大的 hemangiomas : 有文学评论的二个稀罕案例的报告显示文摘 Most hepatic hemangiomas(HHs) are small,asymptomatic and do not require clinical intervention.Surgical resection is only indicated for symptomatic hemangiomas.We report here cases of recurrent HHs in 2 women of 37 and 40 years old,who initially presented with abdominal pain and mass.Radiological examination of each tumor revealed a solitary tumor of 14 and 20 cm in diameter,respectively.Surgical liver segmental resections were performed in both,and the diagnosis of cavernous hemangioma was confirmed.Both patients had recurrent tumor on subsequent radiological examination 4-5 years after the initial surgery.In the first patient,a 15 cm recurrent hemangioma was resected,but multiple hemangiomas were again detected 8 years later occupying the other hepatic lobe,which was not amendable for resection.In the second patient,a 16 cm hemangioma was seen on radiogram,and because the lesion was not symptomatic,conservative observation was offered.Recurrence after liver resection of giant hemangioma is extremely rare.The pathogenesis of tumor progression and recurrence is unknown,as is the management of these patients with recurrent hemangioma,particularly when it is extensive and unresectable.Hongfa Zhu Khaled Obeidat Jie Ouyang Sasan Roayaie Myron E Schwartz Swan N Thung 2012World Journal of Gastrointestinal Surgery2012,4,11:5
