提出了“城市基因改造论”和“畅通城市新模式”。目前城市“有机体”中存在着致病基因——“空间错位”,正是这一致病基因,导致产生了影响城市可持续发展的十大问题:城市占地多、效率低、能耗高、污染重、停车难、治安差、不宜居,以及交通事故多、交通投资巨大等。城市交通问题应该从“城市交通-城市空间-经济-社会”四个层次综合研究,“跳出交通看交通”,铲除“空间错位”这个基因,才能一揽子解决城市交通和城市可持续发展的诸多问题。通过分别构筑车与人的空间,将一个混乱的城市空间变为两个自由空间,从而构建“畅通城市新模式”,既可实现《雅典宪章》所提出的寻找新的街道系统以适应汽车交通特性[1],又可实现建设“以人为本”节约宜人型城市的新目标。

Valveless pumping using a two-stage impedance pump

Impedance pump is defined as a type of valveless pumping mechanism, where an elastic tube is joined with a tube of different impedance, a periodic asymmetrical compression on part of the elastic tube will produce a unidirectional flow. Numerical and experimental studies had been conducted in the past, but little experimental work was found to exploit the principle of multi-stage impedance pumping for fluid transportation. This paper concentrates on the fluid behavior for an open-loop two-stage system experimentally. The aim of this work is to have an insight on the deliverable head and pumping rate of an open-loop two-stage impedance pumping system. This paper generally investigates the effect of different parameters towards the generation of unidirectional flows and composite flow of two opposite directions. Results obtained are of significant values.

Antithrombin deficiency and decreased protein C activity in a young man with venous thromboembolism:

Antithrombin and protein C are two crucial members in the anticoagulant system and play important roles in hemostasis. Mutations in and lead to deficiency or dysfunction of the two proteins, which could result in venous thromboembolism (VTE). Here, we report a Chinese 22-year-old young man who developed recurrent and serious VTE in cerebral veins, visceral veins, and deep veins of the lower extremity. Laboratory tests and direct sequencing of and were conducted for the patient and his family members. Coagulation tests revealed that the patient presented type I antithrombin deficiency combined with decreased protein C activity resulting from a small insertion mutation c.848_849insGATGT in and a short deletion variant c.572_574delAGA in . This combination of the two mutations was absent in 400 healthy subjects each from southern and northern China. Then, we summarized all the mutations of the and gene reported in the Chinese Han population. This study demonstrates that the combination of antithrombin deficiency and decreased protein C activity can result in severe VTE and that the coexistence of different genetic factors may increase the risk of VTE.
