The Pd2+ ion coordinates with four S atoms from SCN- groups forming a regular square planar configuration. The K+ ion is surrounded by six ether oxygen atoms,one O atom from water molecule coordinated to two K+ions and one N atom from SCN- group to form a distorted hexagonal bipyramid. Two K atoms are linked with one Pd atom by two bridging SCN- groups forming a chain molecular array in the crystal.

Correlation of aPKC-ι and E-cadherin expression with invasion and prognosis of cholangiocarcinoma

The 2006 International Conference on Industrial Design & The 11th China Industrial Design Annual Meeting

作者： Yang jian Wen ming wang Jun wang Junhua (The Academy of Equipment Command & Technology, 101416)

In laser propulsion, the application of multi - reflecting laser focus system is limited to some extent because of its difficult process and strict coaxial requirements in installation and debugging. Beginning with analyzing beam path design principles of several typical focus systems home and abroad, we put forward a laser side focus system. The equations of reflecting surfaces are established , and methods for process, installation and debugging of the system are presented. The results show;laser side focus system is easy to process and convenient to adjust. It successfully realizes the breakdown of air and is well applied in the experiment of researching plasma characteristics. This paper provides study thought and design method for laser focus system design in engineering technique field.

BACKGROUND: The abnormal expression of atypical protein kinase C-ι (aPKC-ι) subtype and E-cadherin play important roles in tumor occurrence and progression This study was designed to investigate the correlation of expression of aPKC-ι and E-cadherin with the clinicopathological characteristics and prognosis of cholangiocarcinoma, and to analyze the molecular mechanisms of invasion and metastasis of the tumor. METHODS: EnVision immunohistochemistry was used to detect the expression of aPKC-ι and E-cadherin in 9 specimens of benign bile duct tissues, 35 specimens of cholangiocarcinoma and 6 specimens of metastatic cholangiocarcinoma. The relationship of the expression with clinicopathological characteristics, invasion and prognosis of cholangiocarcinoma was analyzed. A multivariate regression analysis was made of these data by the Cox proportional hazard model. RESULTS: The positive expression level of aPKC-ι in cholangiocarcinoma was remarkably higher than that in benign bile duct tissues (68.6% vs. 11.1%, P=0.006) but the expression level of E-cadherin was lower in cholangiocarcinoma than in benign bile duct tissues (37.1% vs. 88.9%, P=0.016). Correlation analysis revealed that the expression of aPKC-ι was positively related to tumor differentiation and invasion, whereas that of E-cadherin was entirely the contrary. Moreover, there wasa negative relationship between the expression of aPKC-ι and that of E-cadherin (r=-0.287, P<0.05). Univariate analysis showed that the overall survival rate of the group with a higher expression of aPKC-ι in cholangiocarcinoma was remarkably lower than that of the group with a lower expression (P<0.01); multivariate analysis revealed that the expressions of aPKC-ι and E-cadherin are important prognostic factors for cholangiocarcinoma (P<0.05). CONCLUSIONS: The expressions of aPKC-ι and E-cadherin may reflect the differentiation and invasive potential of cholangiocarcinoma. aPKC-ι and E-cadherin may be independent prognostic factors an

研究了供应商和制造商产出随机且零售商面临随机需求的三级供应链协调模型,决策变量为供应商的原材料投入量、制造商的订购量和零售商的订购量。分析了集中决策下供应链协调基准的唯一性,论证了回购契约及其与产出风险分担组合契约的协调性。研究结果表明,对于产出和需求不确定的三级供应链,仅考虑在制造商和零售商之间采用回购契约可改善供应链绩效,但并不能实现供应链的全局最优化,而从风险分担的角度设计的回购和产出风险分担组合契约不仅能有效的协调供应链,且在一定条件下,各供应链成员的利润还能获得帕累托改进。通过算例验证了以上结论的正确性,并分析了回购价格对订购量、原材料投入量和利润的影响,以及各供应链成员对契约的偏好。

Dissection of the superior mesenteric artery （SMA） not associated aortic dissection is an uncommon event. The pathogenesis remains unclear. Diagnosis has become more efficient due to recent advances in imaging techniques and increased awareness of mesenteric vessel diseases. Early recognition has led to early interventions. Although there is still no consensus on the best option of management for this disease, an increasing number of patients in recent years have been reported to be treated successfully by non-operative approaches （medical therapy and/or percutaneous endovascular repair） rather than operations. We report the diagnosis and non-operative managements of isolated dissection of SMA in the acute stage in two cases at the First Hospital of China Medical University from October to December in 2006.
