It needs the foundation of system and the guarantee of organizational system for anti-corruption,but it is more necessary to build and form an effective anti-corruption mechanism,so that the anti-corruption can be really put into practice. Anti-corruption mechanism refers to a organic operation system of the interaction,interconnection and constraint between the constituent elements( parts) and elements of national anti-corruption,and as a system,anti-corruption mechanism should have the characteristics of system aticness,comprehensiveness,transparency,legalization,public participation,scientific dynam ic,and internationalism. The construction of deepening anti-corruption mechanism is the need for reconstructing the ruling legitimacy of the party and the governm ent. Adhering to the principle of treating both root causes and symptoms is necessary in the construction of anti-corruption m echanism,com bating and punishing corruption is an important part of anti-corruption,and the prevention and control of corruption is the basic project of anti-corruption. Therefore,the construction of prevention and control mechanism in the anti-corruption mechanism has a more far-reaching significance. 展开更多

Under axial rubbing action, the failure mode of the core yarn is the stripping of the sheath from the core. This paper introduces a method to test the anti - stripping property of the core yarn. With a modified Universal Testing Machine, the stripping resistance of friction spun core yarn can be continuously measured. Some factors Influencing the measurements are discussed in detail. The testing results are compared with those from a Y731 Yarn Abrasion Tester and fur - ther confirmed by weaving practice. 展开更多

Since ancient times, traditional medicines have been in the usage for the treatment of Diabetes mellitus. An edible fruit from traditional medicinal plant Capparis zeylanica (CZ) was studied for its anti diabetic, insulin secretagogue activities and mechanisms involved in it. In Streptozotocin induced diabetes rats, oral administration of Capparis zeylanica methanolic extract (CZME) (200 mg/kg body weight) for 28 days showed a significant reduction in blood glucose levels by 35.53% and enhanced circulating insulin levels by 81.82% than the diabetic control rats. The insulin secretagogue activity mechanisms of the extract were evaluated by using mouse insulinoma beta cell line (MIN6-β). The extract stimulated insulin release in dependent manner of glucose concentration (3 - 16.7 mM) and extract dose (5 - 500 μg/mL). The insulin releasing effect of the extract was significantly enhanced by 3-isobutyl-1-methyl xanthine, glibenclamide, elevated extracellular calcium and K+ depolarized media. This insulin release was significantly reduced in calcium blocking conditions (by nifedipine and EGTA), in the presence of potassium channel opener (diazoxide). Hence, anti diabetic activity of CZME might be a result of its stimulatory effect on insulin release from pancreatic beta cells via KATP channel dependent and independent ways. These results indicate that CZ fruits have the potential to use in diabetes therapy. 展开更多

In this work, the exp(-φ (ξ )) -expansion method is used for the first time to investigate the exact traveling wave solutions involving parameters of nonlinear evolution equations. When these parameters are taken to be special values, the solitary wave solutions are derived from the exact traveling wave solutions. The validity and reliability of the method are tested by its applications to Nano-ionic solitons wave’s propagation along microtubules in living cells and Nano-ionic currents of MTs which play an important role in biology. 展开更多

[目的]早期及时的诊断及正确的治疗弥漫性血管内凝血(DIC),以减少误诊及死亡率,提高治愈率。[方法]回顾性统计大连医科大学第二临床学院近3年来各科疾病合并DIC100例的一般状况及其基础疾病、诊断和治疗、转归情况。[结果]内科系统疾病DIC发生率最高,占82%,其中以血液系统疾病,尤其是M3型白血病最易合并DIC,占22%;其次为实体瘤,占7%;再次为外科系统疾病,占6%;最后是神经系统疾病和妇科病,分别占4%和1%。常规治疗效果总治愈率为67%,死亡率为33.0%,脑出血是其主要死因。[结论]DIC的诊断除了目前应用的标准外,还要结合凝血因子和血液凝固调节蛋白的活性测定及血栓止血标志物来诊断。DIC一经确诊就要尽早治疗,早期治疗可以明显降低死亡率,提高治愈率。治疗关键是祛除原发病,肝素化治疗。晚期以纤溶为主、有严重出血倾向,方可抗纤溶治疗。 展开更多
