Controllable high repetition rate gain-switched Nd:YVO4 microchip laser

We demonstrated a monolithic, compact, diode-pumped gain-switched Nd:YVO4 laser at 1.064 μm wavelength with controllable repetition rate of 1 Hz to 25 kHz. Stable gain-switched pulse train with maximum repetition rate of 25 kHz and pulse width of 16 ns was obtained.     

《普通高中语文课程标准》评析——以叶圣陶阅读课程理论为视点

《普通高中语文课程标准》(实验稿)在强调加强阅读实践活动、学习并运用阅读策略与方法、培养“读解和欣赏的能力”及体会民族文化、培育民族精神等诸多方面继承并发展了叶圣陶的阅读课程理论,但在选文标准、选文种类、文言文阅读要求及情感态度培养等四个方面却与叶圣陶的阅读教学思想存在较大的差异。应该将叶圣陶的更多阅读教学思想融入到《普通高中语文课程标准》中,以增强其可操作性,从而使一直悬而未决的阅读课基本课程内容及其序列问题能尽早得以解决。

GCr15轴承钢特大锻材的研制

GCr15轴承钢特大锻材的研制，选用低S、P的生铁，由VHP炉、LF炉、VD 炉从初炼到精炼的冶炼工艺，形成6．3吨矩形锭；经1200－1220℃的高温加热，12小时的高温扩散，出炉停留5分钟以上，然后镦粗、拔长锻造工艺，得到成品材。该成品材经光谱分析及化学分析法检验：硬度63－65HRC，晶粒度8－9级，化学成份：S≤0．003％；P≤0．0014％；C，1．01－1．04％Cr，1．38－1．46％，均达到较好水平。     

Troponin T and Heart Type Fatty Acid Binding Protein (h-Fabp) as Biomarkers in Patients Presenting with Chest Pain

Acute coronary syndrome (ACS) is a term for a range of clinical signs and symptoms suggestive of myocardial ischemia. It results in functional and structural changes and ultimately releasing protein from injured cardiomyocytes. These cardiac markers play a major role in diagnosis and prognosis of ACS. This study aims to assess the efficacy of heart type fatty acid binding protein (h-FABP) as a marker for ACS along with the routinely used hs-TropT. In our observational study, plasma h-FABP (cut-off 6.32 ng/ml) and routinely done hs-Trop T (cutoff 0.1 and 0.014 ng/ml) were estimated by immunometric laboratory assays in 88 patients with acute chest pain. Based on the clinical and laboratory test findings the patients were grouped into ACS (n = 41) and non-ACS (n = 47). The diagnostic sensitivity, specificity, NPV, PPV and ROC curve at 95 % CI were determined. Sensitivity of hs-TropT (0.1 ng/ml), hs-TropT (0.014 ng/ml) and h-FABP were 53, 86 and 78 % respectively and specificity for the same were 98, 73 and 70 % respectively. Sensitivity, specificity and NPV calculated for a cut-off combination of hs-TropT 0.014 ng/ml and h-FABP was 100, 51 and 100 % respectively. These results were substantiated by ROC analysis. Measurement of plasma h-FABP and hs-TropT together on admission appears to be more precise predictor of ACS rather than either hs-Trop T or h-FABP.

Lipids changes in liver cancer

Liver is one of the most important organs in energy metabolism. Most plasma apolipoproteins and endogenous lipids and lipoproteins are synthesized in the liver. It depends on the integrity of liver cellular function, which ensures homeostasis of lipid and lipoprotein metabolism. When liver cancer occurs, these processes are impaired and the plasma lipid and lipoprotein patterns may be changed. Liver cancer is the fifth common malignant tumor worldwide, and is closely related to the infections of hepatitis B virus （HBV） and hepatitis C virus （HCV）. HBV and HCV infections are quite common in China and other Southeast Asian countries. In addition, liver cancer is often followed by a procession of chronic hepatitis or cirrhosis, so that hepatic function is damaged obviously on these bases, which may significantly influence lipid and lipoprotein metabolism in vivo. In this review we summarize the clinical significance of lipid and lipoprotein metabolism under liver cancer.
