Twenty native cultivars representing Yunjie-growing eco-types in China were selected as material in this study. Twelve out of the 64 tested random decamer primers were able to identify 131 stable RAPD bands from these Yunjie cultivars. Of them 105 bands, or 80.15% of the total, were polymorphic. Most Yunjie cultivars from the same ecotype had their characteristic DNA bands. Cluster analysis by unweighted pair group method of arithmetic means(UPGMA)suggested that the 20 Yunjie genotypes could be divided into four groups. The genetic distances among the 20 cultivars varied from 0.117 8 between Shuozhou and Shenchi to 0. 499 4 between Hetian and Xiliang. Hetian alone could be a new type of Yunjie identified in China because it had the greatest genetic distance from all the other tested cultivars. These results indicate that Chinese Yunjie have abundant genetic diversity. Classification of Chinese Yunjie based on the RAPD information was in good agreement with the relationships between these Yunjie cultivars in their geographic origins and their plant morphology.展开更多

During this period of time, China has made remarkable achievements in the field of infrastructure construction, and its growth plays a very important role in the upward advancement of the national economy. In addition, the overall comprehensive situation of construction management is also on the rise. As far as its projects are concerned, the effectiveness of comprehensive management of such projects is closely related to its process and quality. Therefore, it is a necessary measure for construction enterprises to carry out construction project management, and it is necessary to have a correct understanding of the importance of management. Firstly, the importance of construction project management is discussed, and then the problems existing in the current construction project management are analyzed. Finally, specific solutions are formulated in combination with the relevant regulations of the current construction industry, for reference only.展开更多

Methods: from August 2017 to December 2019, 60 patients with DF of Wagner grade 3 ~ 4 were selected from the Department of Endocrinology, Department of orthopedics and rehabilitation of Loudi central hospital. The patients were randomly divided into the control group with routine treatment and Ilizarov tibial transverse bone transfer on the basis of routine treatment, with 30 patients in each group. The pain (VAS) score, ankle brachial index, affected foot skin temperature, ulcer healing rate, 10 # g nylon filament measurement and limb salvage rate were compared between the two groups before and after treatment, and the incidence of postoperative complications in the study group was analyzed. Results: after treatment, the VAS score, skin temperature of affected limbs, 10 g nylon thread test, ankle brachial index, ulcer healing rate and limb salvage rate in the study group were significantly better than those in the control group (P < 0.05);Three patients in the study group had red and swollen skin around the nail path during treatment, which improved after antibiotic treatment. Conclusion: transverse tibial bone transfer can improve the clinical symptoms, lower limb blood supply and peripheral nerve function, accelerate ulcer healing and improve limb salvage rate in patients with DF, which is safe and effective.展开更多
