评估Ahmed青光眼阀(Ahmed glaucoma valve,AGV)植入治疗难治性青光眼的长期疗效及并发症。方法:回顾性分析13例13眼接受Ahmed青光眼阀植入,最短随访18mo的难治性青光眼患者。所有患者均在术前及术后1,3,6mo,1a及1a以后行全面的眼科检查,眼压测量,记录并发症及抗青光眼的药物需求。结果:患者平均年龄27.3±16.0岁。所有患眼(100%)接受至少一次前置小切口手术。平均随访61.3±30.8mo。在少量药物的作用下,12mo时眼压由35.0±7.0mmHg降至18.2±7.9mmHg,96mo时降至17.0±4.1mmHg,76.9%患者需其他辅助治疗以达到预期的成功疗效。最常见的并发症包括包裹性囊肿8眼(61.5%),置管脱出4眼(30.8%)。结论:包裹性囊肿是最常见的并发症,阻碍了Ahmed青光眼阀植入治疗难治性青光眼。虽然囊肿被抗纤维化药物切除,但没有抗青光眼药物的治疗,眼压仍旧不能很好控制。

High temperature heat-treatment of wood, which is value-added green product, is one of the altematives to chemical treatment. It has better dimensional stability, thermal insulating properties and biological resistance compared to kiln dried wood. It also has dark brown color which is very important for decorative purposes. Unfortunately, this color changes during weathering. Developing a transparent and non-toxic coating for the protection of heat-treated wood against discoloration without changing its natural appearance is the main objective of this study. For this purpose, waterborne acrylic polyurethane base was chosen because of its durability against weathering and non-toxic nature. Natural antioxidants which are extracted from barks and CeO2 nano particles （alone or together with lignin stabilizer） were used as additives to develop different coatings. The protective characteristics of these coatings were compared with highly pigmented and toxic industrial coating under accelerated weathering conditions. The results showed that acrylic polyurethane coatings protected wood better compared to commercially available coating tested in this study. The chemical modifications during accelerated weathering of coated and heat-treated wood surfaces were monitored by X-ray photoelectron spectroscopy analysis. The morphological changes took place during weathering were studied by fluorescence microscope analysis.

Purpose: K-ras mutations were reported to be in 40% - 60% of patients with sporadic colorectal cancers (CRCs). HER-2/neu oncogene that is important in breast carcinoma was reported in CRCs in several studies. The aims of our study are to determine;the frequency of K-ras mutation in CRC and positivity of HER-2/neu, the relation between K-ras mutation and HER-2/neu positivity, and also the relation between clinicopathological findings with K-ras mutation and HER-2/neu expression. Methods: Total of 35 colon resection specimen from patients without distant metastasis who were operated due to colorectal adenocarcinoma were included in the study. The sections were examined with light microscopy. Vascular and perineural invasions and pericolonic tumor deposits (PCTD) were investigated. HER-2/neu was applied immunohistochemically. DNA sample obtained from tumor paraffin block was screened for presence of 20 mutations in K-ras gene-codon 12, 13, 61 by AutoGenomics and Infinity Analyzer. Results: K-ras gene mutation was detected in 14 of 35 patients (40%). HER-2/neu positivity was detected in 7 cases (28.57%). There was not any significant correlation between HER-2/neu positivity, K-ras gene mutation and clinicopathological findings. There was direct correlation between PCTD and vascular invasion. Conclusions: There was not correlation between K-ras mutation and clinicopathological findings similar to several other studies. The relation between HER-2/neu expression and clinicopathological findings was not found.

为研究纤维增强复合材料(Fiber Reinforced Polymer,FRP)筋超高性能海水海砂混凝土(Ultra-high Performance Seawater Sea-sand Concrete,UHPSSC)梁的抗剪性能,采用三点弯曲试验,探究剪跨比、箍筋间距和筋材类型(CFRP、BFRP、HFRP)对FRP-UHPSSC梁抗剪性能的影响规律.试验结果表明:FRP-UHPSSC梁在加载时裂缝发展迅速,破坏时具有明显的脆性特征;跨中荷载-挠度曲线在首条裂缝出现前后均呈现出双线性变化,裂缝出现后梁的荷载-挠度关系曲线斜率变小,挠度增长加快;FRP-UHPSSC梁的抗剪承载力随剪跨比和箍筋间距的增大而减小,剪跨比相同的试验梁,其开裂荷载基本相同;筋材的弹性模量越大,梁的抗剪承载力越高,同时也越能抑制梁的竖向变形;最后采用4部规范中的抗剪公式对试验工况进行分析,规范公式对BFRP-UHPSSC梁和HFRP-UHPSSC梁抗剪承载力计算的最小误差分别超过40%和30%,筋材类型不同的试验工况抗剪承载力计算结果差异较大.

由于美国高校主要采取签约体系薪资制度,在这一制度下,反映高校教师能力以及校级差异的因素包括学衔、科研教学比重、院校类型,它们成为教师薪酬的主要影响因素有其必然性。同时,在美国高等教育举办体制多样化的背景下,公私立高校教师薪酬间的差距与国家整体经济状况及国家对高等教育的支持力度有着密切的联系。高校教师在性别和种族上的差异性,在多元文化的美国社会中也能找到其存在的基础。近年来,由于市场的作用,学科因素对美国高校教师薪酬的影响愈来愈大,加之薪酬的集体谈判以及高等教育内职业构成比例的改变,这些都成为影响美国高校教师薪酬的重要的潜在原因。

Remote cerebellar hemorrhages (RCHs) are rare complications of intracranial or spinal interventions. We describe a patient with an RCH that occurred after a frontal lobectomy for an intracranial tumor. A 41-year-old female patient with a headache and partial seizures underwent a right frontal lobectomy upon detection of a right frontal mass. An RCH (zebra sign) was detected on a control cranial computed tomography (CT), which was performed upon detection of frontal lobe syndrome and mild ataxia in the patient postoperatively. Although the mechanism underlying the occurrence of RCHs after intracranial procedures is not clear, they have been attributed to an imbalance between intravascular pressure and cerebrospinal fluid (CSF) due to rapid drainage of the fluid, causing bleeding in the cerebellar parenchyma. Generally, bilateral superior cerebellar injury produces parallel flat hyperdense areas known as the zebra sign on CT. The prognosis of a cerebellar hemorrhage is generally good, and it can be treated with a conservative approach. Controlled drainage of CSF during surgery and selecting an appropriate surgical position perioperatively will reduce the risk of RCHs.

叶斯柏森在《语言论:语言的本质、发展和起源》中,通过追溯语言历史的方法,在分析原始语言结构特点的基础上,提出了语言起源于追求娱乐和爱情的歌唱。这种声音的混合物最开始仅仅是情感表达的叫喊,后来转变成专有名词,声音与意义相结合,而通过"隐喻性转移",这种表达能够用于其他场合而使语言得以继续发展。时至今日,叶氏的理论仍具有学术价值和现实意义。

Spontaneous coronary artery dissection(SCAD) is a rare disease that is usually seen in young women in left descending coronary artery and result in events like sudden cardiac death and acute myocardial infarction. A 70-year-old man was admitted to the emergency department with chest pain which started 1 h ago during a relative's funeral. The initial electrocardiography demonstrated 2 mm ST-segment depression in leads V1-V3 and the patient underwent emergent coronary angiography. SCAD simultaneously in two different coronary arteries [left anterior descending(LAD) artery and left circumflex(LCx)] artery was detected and SCAD in LCx artery was causing total occlusion which resulted in acute myocardial infarction. Successful stenting was performed thereafter for both lesions. In addition to the existence of SCAD simultaneously in two different coronary arteries, the presence of muscular bridge and SCAD together at the same site of the LAD artery was another interesting point which made us report this case.

基于1961-2017年6-8月新疆北部47个观测站点的逐日降水资料,根据百分位法定义不同站点的夏季极端降水阈值,分析了新疆北部地区夏季极端降水事件和最大日降水的时空分布特征、贡献率及其与海拔的关系。结果表明:新疆北部地区夏季极端降水事件和最大日降水量的各个特征量分布存在明显的时空差异,空间上夏季极端降水事件、最大日降水量表现为山区高、盆地低的特点,在海拔2 000m左右存在一个最大降水带;夏季极端降水事件和最大日降水量呈增多、增强的趋势,并从20世纪90年代前后开始有明显的增加。夏季极端降水事件主要以单日为主,夏季极端降水贡献随时间呈缓慢增加的趋势,而夏季极端降水过程贡献和最大日降水贡献随时间变化呈下降趋势。
