Research on Valuation Methods of Chinese Insurance Company

随着全球金融一体化以及我国金融业综合经营的逐步放开，国际金融保险集团综合经营的绝对优势以及国内以银行业为核心的金融集团的迅速崛起，使国内保险公司面临严峻的竞争形势。为提高整体竞争力和抵御风险能力，国内保险公司纷纷寻求自身的发展之路，上市与金融集团化经营成为目前中国保险业发展的新潮流。因而，如何确定保险公司的投资价值成为理论与实务界共同关注的话题。本文采用定性与定量相结合的分析方法，在对各种公司价值评估方法进行解析的基础之上，结合我国保险行业发展特点以及保险公司经营特性，对适合于中国保险公司价值评估方法进行理论与实践上的探索，以便建立一套合理的保险公司价值评估方法体系。首先，文章从公司价值评估发...As the development of financial globalization and comprehensive management has be gradually liberalized in Chinese financial field, the international and local financial group has shown absolute superiority in business.

Effects of Different Concentrations of Alcohol On Spatial Learning and Memory Ability and Hippocampal GFAP/NEUN in Mice

目的 探究长期饮酒对小鼠行为学能力以及空间学习记忆能力的影响。方法 雄性KM小鼠45只,随机分成对照组（Con）,低剂量组（Low）和高剂量组（High）。分别每天对照组0.10 ml/10 g自来水,低剂量组0.05 ml/10 g的56度红星二锅头,高剂量组0.10 ml/10 g的56度红星二锅头进行灌胃。连续灌胃13 d后进行衣架实验测行为学能力,最后取海马做免疫荧光染色观察海马神经元和星形胶质细胞。结果衣架实验得分,自主活动数值总体显示Low组高于其他两组,而且与Con组差异显著;免疫荧光结果显示无论是CA3区,还是DG区,海马的星形胶质细胞含量与神经元细胞含量比值上Con,Low,High三组依次升高,而且Con,High之间对比,P〈0.05,差异有统计学意义。结论 长期大量饮酒会损伤学习记忆能力,但适量饮酒可以促进机体兴奋性和活动度。Objective To investigated the effects of long-term alcohol drinking on the ability of learning and memory in mice. Methods 45 male KM mice were randomly divided into control group （Con）, low dose group （Low） and high dose group （High）.

Methods 70 patients with liver cancers, including 2 small tumors and 68 large tumors, were examined by ultrasound, CT, AFP assay, and diagnosed by histopatholopy of needle biopsy. The patients received injection of hematoporphyrin derivative(HPD) i.v. in a dose of 5 mg/kg body weight 48 h prior to laser irradiation. An argon laser pumped dye laser system was used to give a CW laser beam at 630 nm. The light beam was split and coupled into three optical fibers. An ultrasound-guided percutaneous liver puncture was performed and optical fibers were inserted into the tumors via 18G needles. Efforts were made to ensure that irradiation points were distributed in entire tumor volume and a light output of 300～350 mW for 12 minutes per point was used. The patients were examined with routine blood test, liver functions, AFP assay and USG at one week after treatment. A month later they were reexamined by needle biopsy and received next PDT treatment. Results Total 170 treatments were performed in the 70 patients. Among them 30 cases were treated for only once, 12 cases twice, 12 cases 3 times, and 16 cases 4 times or more. All 70 cases were followed up for 1-5 years. The results showed that multiple treatment is more effective than single treatment. The 1-, 2-and 3-years survival rate was 10%, 0, 0 in the group by single treatment, respectively, 50%, 8% and 8% in the group treated twice, and 82%, 50% and 30% in the group treated by 3 or more time, respectively. Three patients from the last group have already been surviving for longer than 5 years. Slight increase of ALT, AST and total bilirubin occurred in only 18%, and mild fever occurred in 17% of the 70 cases for 3-4 days shortly after PDT treatment. No severe complications due to PDT such as severe hemorrhage after liver puncture, hepatic failure, biliary peritonitis or long-lasting liver dysfunctions were observed in our group. Conclusions Photodynamic therapy is effective and safe for the treatment of liver cancers including those following hepatic resection or those failed after embolic chemotherapy by hepatic artery infusion. However, we would suggest that single PDT treatment is not enough and repeated PDT treatments are recommended in order to obtain a significant therapeutic effect to patients with large liver cancers.福建省“95”重点科技项

苯硫酚对固氮酶催化活性的影响

研究了苯硫酚对棕色固氮菌固氮酶催化底物还原活性的影响。结果表明:当反应体系中固氮酶钼铁蛋白与苯硫酚的摩尔比为1:4时,固氮酶的乙炔还原活性比对照组下降了62.3％,下降的幅度随着苯硫酚浓度的升高而增大;但在乙炔存在的情况下,固氮酶的放H_2活性随着苯硫酚的浓度的升高而升高。在氩气氛下,苯硫酚浓度的升高对固氮酶放H_2活性的影响不明显。这一现象有可能是由于苯硫酚取代与铁钼辅基的Fe_1原子连接的半胱氨酸的巯基而引起的

甘露糖对巨噬细胞炎症反应的双向调节作用

目的探讨甘露糖（Man）对炎症反应的调控及其机制，为甘露糖在炎症疾病中的应用提供依据。方法利用不同浓度的甘露糖处理RAW264.7巨噬细胞24 h或48 h，细胞计数检测增殖情况。低浓度（2 mmol/L）和高浓度（20 mmol/L）Man预处理RAW264.7细胞12 h，然后脂多糖（LPS）处理8 h或24 h，收集mRNA、蛋白质及培养上清，通过Q-PCR、Western blot和ELISA检测炎症相关指标以及甘露糖受体（CD206）的变化。结果在5 mmol/L以下，细胞增殖随Man的浓度增加而增加；在5 mmol/L以上，则相反。和LPS处理相比，LPS + 甘露糖2 mmol/L（Man2）能够增高IL-1β、IL-12和TNF-α的mRNA水平以及蛋白水平（均P&lt;0.05）；LPS + Man20显著抑制IL-1β、IL-12、TNF-α、IL-6和CCL2的mRNA水平和蛋白水平（均P&lt;0.05）。网络药理学预测甘露糖及其代谢产物的潜在作用靶点有包括AKT和STAT3在内的20个蛋白。Man2可协同LPS刺激AKT和STAT3的磷酸化（均P&lt;0.05），而Man20可抑制LPS诱导的AKT、p65和ERK磷酸化水平的增加（均P&lt;0.05）。单独甘露糖处理可抑制AKT、STAT3和p65的磷酸化（均P&lt;0.05）。结论不同浓度的甘露糖对炎症反应具有不同的作用。低浓度甘露糖能够促进LPS诱导的巨噬细胞炎症反应，而高浓度的甘露糖具有抑制LPS诱导的炎症反应，其机制与调控AKT、STAT3、p65和ERK的活性有关
