1Adenoid 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
2Effects of Flower Buds Extract of Tussilago farfara on Focal Cerebral Ischemia in Rats and Inflammatory Response in BV2 Microglia显示文摘Objective: To investigate the effects of the flower buds extract of Tussilago farfara Linné(Farfarae Flos; FF) on focal cerebral ischemia through regulation of inflammatory responses in activated microglia. Methods: Brain ischemia was induced in Sprague-Dawley rats by a transient middle cerebral artery occlusion(t MCAO) for 90 min and reperfusion for 24 h. Twenty rats were randomly divided into 4 groups(n=5 per group): normal, t MCAO-induced ischemic control, t MCAO plus FF extract 300 mg/kg-treated, and t MCAO plus MK-801 1 mg/kg-treated as reference drug. FF extract(300 mg/kg, p.o.) or MK-801(1 mg/kg, i.p.) was administered after reperfusion. Brain infarction was measured by 2,3,5,-triphenyltetrazolium chloride staining. Neuronal damage was observed by haematoxylin eosin, Nissl staining and immunohistochemistry using anti-neuronal nuclei(Neu N), anti-glial fibril ary acidic protein(GFAP), and antiCD11 b/c(OX42) antibodies in ischemic brain. The expressions of inducible nitric oxide synthase(i NOS), tumor necrosis factor(TNF-α), and hypoxia-inducible factor-1 a(HIF-1α) were determined by Western blot. BV2 microglial cel s were treated with FF extract or its main bioactive compound, tussilagone with or without lipopolysaccharide(LPS). Nitric oxide(NO) production was measured in culture medium by Griess assay. The expressions of i NOS, COX-2 and pro-inflammatory cytokines mRNA were analyzed by reverse transcription-polymerase chain reaction. The expression of i NOS, and COX-2 proteins, the phosphorylation of ERK1/2, JNK, and p38 MAPK and the nuclear expression of NF-κB p65 in BV2 cells were determined by Western blot. Results: FF extract significantly decreased brain infarctions in ischemic rats(P<0.01). The neuronal death and the microglia/astrocytes activation in ischemic brains were inhibited by FF extract. FF extract also suppressed i NOS, TNF-α, and HIF-1α expression in ischemic brains. FF extract(0.2 and 0.5 mg/m L, P<0.01) and tussilagone 20 and 50 μmol/L, P<0.01) significantly decreased LPS-induced NO production in BV2 microglia through downregulation of i NOS m RNA and protein expression. FF extract and tussilagone significantly inhibited LPS-induced expression of TNF-α, IL-1β, and IL-6 m RNA, and also suppressed the phosphorylation of ERK1/2, JNK and p38 MAPK and the nuclear expression of NF-κB in a dosedependent manner. Conclusion: FF extract has a neuroprotective effect in ischemic stroke by the decrease of brain infarction, and the inhibition of neuronal death and microglial activation-mediated inflammatory responses.Ji Hye Hwang Vinoth Kumar R Seok Yong Kang Hyo Won Jung Yong-Ki Park 2018Chinese Journal of Integrative Medicine2018,24,11:13
3术前肌电图和脑干听觉诱发电位与面肌痉挛微血管减压术后迟发性面瘫发生的关系(英文)显示文摘Background Delayed facial palsy ( DFP) after microvascular decompression ( MVD) in patients with hemifacial spasm ( HFS) is not uncommon,but the cause remains unknown. Objectives To assess whether intraoperative electromyography ( EMG) and brainstem auditory evoked potential ( BAEP) can predict DFP after MVD. Methods Between September 2009 and February 2011 we examined 86 patients,9 of whom ( 10. 4% ) developed DFP after MVD on the same side. All patients underwent MVD and were followed - up for a median period of 13 months ( range 6-22) . We retrospectively examined intraoperative facial EMG and BAEP findings using our MVD patients' registry. We excluded secondary HFS and immediate postoperative facial palsy after MVD in this study. We assessed the prevalence and clinical characteristics of DFP and compared EMG and BAEP findings between DFP and non-DFP groups. Results: All pa- tients recovered completely,with a mean time to recovery of 37. 8 days ( range 22-57) . There were no significant differences between DFP and non - DFP patients in terms of the amplitude and latency of intraoperative EMG and BAEP. Conclusion The usefulness of intraoperative facial EMG and BAEP is limited and cannot predict DFP after MVD for HFS. We speculate that DFP after MVD is not associated with permanent nerve damage according to the EMG findings.Kim HJ Park YS Ryu JS Huh R Han I Shin DA Kim TG Cho KG Chung SS 2012中华神经外科疾病研究杂志2012,11,4:13

5地理信息系统技术在伤寒发热监测中应用显示文摘目的运用地理信息系统(GIS)技术,了解各居民点发热流行率和评价以医疗机构为哨点的伤寒发热监测系统的敏感性。方法收集医学人口普查数据、疾病监测系统信息数据、现场采集居民居住点全球卫星定位数据等资料,建立GIS系统和以人口为基数的发热监测系统;对所有发热就诊病人进行身份和居住地址确认,并制作各居民点年发热就诊率GIS分布图。结果共采集3776个居民居住的全球定位系统(GPS)定位点,人群发热就诊率为1.11‰,发热就诊人次占总门诊人次的16.3%,监测区内的发热就诊病人占所有发热就诊病人的83.5%。在3种类型的医疗机构中,门诊量以个体门诊类最多,但其发热就诊人次占总门诊人次的比率最低(12.6%)。监测区内发热1d或以上的病人地址和身份(ADDRESS-ID)确认率达到95%。根据居民点年发热就诊率GIS分布图,发热就诊率最高的居民点达到17.81‰,最低为0;发热就诊率高的居民点多集中在城市。结论利用GIS技术可直观准确的了解疾病流行率的分布,可迅速直观的寻找出监测系统中的薄弱环节和推断出可能存在的问题。杨进 董柏青 张杰 廖和壮 梁大斌 吴兴华 司国爱 杨宏徽 Jin Kyung Park R Leon Ochiai Camilo J Acosta Moharmmad Ali John D Clemens 2007中国公共卫生2007,23,9:8
