In current stage of China Industrial Transfer, how to select the leading industries is an extremely difficult decision. In this research, we study the selection problem of Jiangbei Industrial Clusters in Anhui Province. Total thirty-three industries can be transferred to Jiangbei Industrial Clusters, however due to limited capacity, Jiangbei Industrial Clusters can only accommodate a few of them. The difficulties of such decision include： 1） the decisions are qualitative within a complex and uncertain environment; 2） the number of alternatives is beyond the upper bound of comparing elements in general decision making methods. We introduce a new methodology-the Orders-of-Magnitude approach of the Analytic Hierarchy Process （OM-AHP） to solve such selection decision. The OM-AHP follows AHP philosophy to structure qualitative questions and uses ＂pivot＂ element to handle the situation when the alternatives become more than seven. By employing OM-AHP methodology, we found the modern logistics industry and ship ＆ marine equipment etc., are identified to be the leading industries; particularly, we recommend to give higher priority in modern logistics industry and the advanced equipment manufacturing industry, given these two industries could dramatically improve the overall comprehensive economic strength and significantly enhance competitive advantages of the Jiangbei Industrial Clusters.

A geological event that happened at the end of the Middle Permian resulted in different levels of erosion in a shallow-water platform of South China, which led to diverse geological records in different sections. The Lianziya section in western Hubei Province of South China has a well-exposed stratigraphic sequence of the late Middle Permian rocks with abundant fossils and sedimentary facies types, providing new evidences for understanding the evolution of marine biota and environment in the late Middle Permian. Our study shows that four fossil communities can be recognized with the change of sedimentary facies in the late Middle Permian: Foraminiferal-algal community, phylloid algal community, bryozoan community and Ungdarella community. The foraminiferal-algal community is dominated by fusulinids and calcareous algae, but was soon replaced by the phylloid algal community. With an increase of terrestrial input, the phylloid algal community was again replaced by the bryozoan community. Near the end of the Middle Permian, with a decrease of terrestrial input, the bryozoan fossil community disappeared while the Ungdarella community became dominant. A 10 cm-thick weathered crust occurred at the top of the Middle Permian limestone, marking a large amplitude fall in sea-level and the beginning of a terrestrial erosion stage. The sedimentary facies and fossil community changes in the Lianziya section indicates that the Middle Permian crisis was a gradual process while the sea-level fall mainly occurred in the latest Middle Permian.

Diabetic retinopathy is one of the main causes of visual impairment and blindness on a global scale. At present, thelimitations of anti-vascular endothelial growth factor agents, steroids, laser photocoagulation, and vitreous surgery haveled to a growing awareness of the role of Chinese medicines in the treatment of diabetic retinopathy. This review firstdescribes the ingredients and characteristics of the formulae including Chinese herbal formulaes, Chinese patent drugsand ancient processed drugs and summarizes the application of Chinese medicines and their mechanisms of action in thetreatment of diabetic retinopathy. Due to the complexity of Chinese medicines, in-depth mechanisms, side effects of herb,and drug interactions need to be elaborated in future research. Chinese medicines have the potencial to protect theresidual eyesight and delay the progression of disease, thereby offering a beneficial, exploitable option in thetreatment/prevention of diabetic retinopathy.
