    传统的公司治理各国呈现出不同的特点,美国采取一元制,董事会作为公司运营的核心。德国采取二元制,由股东和职工代表组成监事会,由监事会成员选举产生董事会。日本采取股东会、董事会、监事会三权分立的并列模式。台湾地区和我国采取日本模式。但进入21世纪以来,公司治理已经出现了国际化特征,德国、日本和台湾地区都在21世纪初期进行公司治理的立法改革,引入了美国式的独立董事和审计委员会制度,但同时又保留一些本土化的特点。我国国有控股公司既区别于一般的上市公司,又与许多国家的国有公司存在治理环境上的差异。近年来,我国国有控股公司的内部人控制现象十分严重,公司管理层的腐败也让人触目惊心。尽管我国《企业国有资产法》...When relating to the traditional corporate governance, every country has its feature. For instance, unified system is adopted in America with a board of directors as the core of business operation; Germans often employ the two-tier system with its board of supervisors composed of shareholders and staff representatives from which the board of directors is generated; Japanese adopt the parallel mode...学位:法律硕士院系专业:法学院法律系_法律硕士(JM)学号:1302009115029

    不同结构的有机配位聚合物在催化、吸附等方面具有广泛的应用前景。因此,选择多酸有机配位聚合物的构筑单元时,既要考虑构筑单元的反应性,还要考虑其结构的影响。杂多酸具有纳米尺寸、组成和结构的可调控性以及优良的催化活性,这吸引着人们将它们作为配位聚合物的重要基元之一。杂多酸、有机配体和金属离子的有机结合,丰富了杂多酸配合物的组成和结构单元;多酸-Ag(I)/Cu(II)-有机配合物中的有机配体、Ag(I)/Cu(II)、多酸可能发挥协同作用,使其具有催化、磁性、荧光等性质。 因此,我们在文献调研的基础上,以Keggin型、Dawson型和Preyssler型阴离子(NaP5W30O11014-)为基...The organic networks have the structural diversity and a broad application prospects as functional materials (such as catalysis, adsorption). Polyoxometalates (POMs) have widely been regarded as molecular building unit for coordination polymers, on account of its electronic, magnetic, catalytic, and photochemical properties.

    使用金纳米粒子为增强因子的表面增强拉曼光谱技术,通过连续小波变换将拉曼光谱信号转化到小波空间(墨西哥帽小波作为小波基)。该步骤能够减轻信号中基线; 变化及随机噪音的影响并找到峰位置和最佳小波尺度系数。依据小波空间中的信息,对混合物光谱及标准谱光谱进行反向搜索得到反向搜索匹配系数(Revere; match quality,; RMQ),作为判断混合物中目标成分是否存在的依据。该算法可对混合物中的目标物质进行准确定性,并已成功应用于多种食品中色素鉴定。食品中色素的检出率; 达到99%,且结果稳健,其效果明显优于传统的命中质量系数法(Hit quality index,; HQI)。这证实了小波空间反向搜索方法是一种快速而准确的拉曼光谱定性算法。In this study, a gold nanocrystal colloid was used as the enhancement; factor for surfaceenhanced Raman scattering (SERS).

    目的观察皂术茵陈方治疗非酒精性脂肪性肝炎(non-alcoholic steatohepatitis,NASH)患者的临床疗效,并探讨其对游离脂肪酸(free fatty acid,FFA)及TNF-α的影响。方法采用随机数字表法将120例NASH患者分为治疗组及对照组,每组60例。治疗组予中药皂术茵陈方,每日1剂;对照组予水飞蓟宾葡甲胺片200 mg口服,每日3次,两组均治疗24周。分别于治疗前后通过检测血清ALT、AST活性及TC、TG水平;行腹部CT计算肝脾CT比值;应用肝组织病理检查评价非酒精性脂肪性肝病活动度积分(NAFLD activity score,NAS)及纤维化程度以评价临床疗效;并检测血清FFA及TNF-α含量。结果与本组治疗前比较,两组治疗后血清ALT、AST、TC、TG、FFA、TNF-α水平、肝组织NAS积分及症状体征积分均明显降低,肝纤维化程度明显改善(P<0.05,P<0.01),且治疗组降低更明显(P<0.05)。治疗24周后,治疗组肝纤维化分期总有效率及临床总有效率分别为80.00%(48/60)、85.00%(51/60),明显高于对照组[60.00%(36/60)、73.33%(44/60)],两组比较,差异有统计学意义(P<0.05,P<0.01)。结论皂术茵陈方可改善NASH患者的临床疗效,其作用可能与抑制血清FFA及TNF-α水平有关。Objective To observe the efficacy of Zaozhu Yinchen Recipe(ZZYCR) on non-alcoholic steatohepatitis(NASH) patients, and to explore its effect on serum free fatty acid(FFA) and tumor necrosis factor α(TNF-α).Methods Totally 120 patients with NASH were randomly assigned to the treatment group(60 cases,treated with ZZYCR, one dose per day) and the control group(60 cases, treated with Silibin Meglumine Tablets, 20 mg each time, thrice per day). The therapeutic course for all was 24 weeks. Serum levels of ALT and AST activities, TC and TG levels were detected before and after treatment. Peritoneal CT was performed in all patients, and CT ratios of liver and spleen calculated. NAFLD activity score(NAS) and degree of hepatic fibrosis were assessed using pathological examinations of liver tissue, and efficacy also evaluated. Serum contents of FFA and TNF-αwere also detected. Results Compared with before treatment in the same group, activities of ALT and AST, serum levels of TC, TG, FFA, and TNF-α, NAS, scores of symptoms and signs all obviously decreased, degree of hepatic fibrosis was obviously improved in the two groups(P < 0. 05, P < 0. 01). These changes were more obviously seen in the treatment group(P < 0. 05). After 24-week treatment, the total effective rate and total clinical efficacy were 80. 00%(48/60 cases) and 85. 00%(51/60 cases) in the treatment group, obviously higher than those in the control group [60. 00%(36/60 cases) and 73. 33%(44/60 cases) respectively], with significant difference(P < 0. 05, P < 0. 01). Conclusion ZZYCR could improve the clinical efficacy of NASH patients, and its mechanism might be associated with inhibiting serum levels of FFA and TNF-α.国家自然科学基金资助项目(No.81503529,81274155);; 福建省自然科学基金面上资助项目(No.2014J01374);; 福建省卫生厅中医药项目(No.wzpw201308);; 厦门市科技计划项目(No.3502Z20134020

    目的肝糖原贮积病(GSD)患者有反复的低血糖发作。本研究的目的是调查分析儿童肝糖原贮积病(GSD)日常血糖及生化指标,为预防低血糖发作和临床管理提供数据支持。方法横断面现场调查研究,收集2024年7月14日在广东省人民医院儿科进行医患交流义诊活动的肝GSD患者及家长的临床资料,现场采集患者及家庭对照者的外周血,检测和分析两组间血糖及生化指标的差异。结果44例肝GSD患者中男34例,女10例。亚型包括GSD Ib型14例、Ia型15例,Ⅲ型2例,Ⅵ型7例,Ⅸ型6例。年龄为7.60(5.08~11.98)岁,所有患者均依赖生玉米淀粉维持血糖。肝GSD患者中平素肝大和反复低血糖发作的患病率分别为77.3%(34/44)和61.4%(27/44)。此次检测有61.4%(27/44)的患者血糖 ≤ 3.9 mmol/L,其中18.2%(8/44)的患者血糖 ≤ 2.8 mmol/L,且均为非Ib型患者,血糖最低值为1.19 mmol/L,医患交流活动期间所有患者均未出现低血糖的症状发作。65.9%(29/44)的家庭受检者的血糖 ≤ 3.9 mmol/L,与肝GSD组比较,低血糖的患病率差异无统计学意义(P =0.658)。生化检测中,肝GSD患者高乳酸血症、高尿酸血症和高胆固醇血症的患病率分别为65.9%、45.5%和9.1%,而家庭对照受检者分别为18.2%,43.2%,15.9%,两组的高尿酸血症和高胆固醇血症患病率差异无统计学意义(P=0.830, P=0.334)。结论肝GSD患者的无症状性低血糖较为普遍,特别是非Ib型患者,需要优化生玉米淀粉的饮食管理,进行动态血糖监测,并注意家庭清淡饮食,降低高尿酸血症和高胆固醇血症发生,避免严重低血糖状态带来的严重不良反应风险、降低并发症
