Separating Leaf and Wood Points in Terrestrial Laser Scanning Data Using Multiple Optimal Scales.

The separation of leaf and wood points is an essential preprocessing step for extracting many of the parameters of a tree from terrestrial laser scanning data. The multi-scale method and the optimal scale method are two of the most widely used separation methods. In this study, we extend the optimal scale method to the multi-optimal-scale method, adaptively selecting multiple optimal scales for each point in the tree point cloud to increase the distinctiveness of extracted geometric features.

[Influence of integrated traditional Chinese and Western medicine therapy on serum resistin levels in patients with severe acute pancreatitis: a randomized controlled trial].

Background: Resistin level is high in patients with severe acute pancreatitis (SAP), and resistin is expected to be a new marker for evaluating the severity of acute pancreatitis.

Objective: To explore the influence of integrated traditional Chinese and Western medicine therapy on serum resistin levels in SAP patients.

Design, Setting, Participants And Interventions: Twenty-eight SAP patients meeting inclusion criteria from Department of Integrated Traditional Chinese and Western Medicine, West China Hospital, Sichuan University were included, and the patients were randomly divided into treatment group and placebo group.

[Simultaneous determination and pharmacokinetic studies of ferulic acid and paeoniflorin in human serum by high performance liquid chromatography after oral administration of Modified Xiao-yao Decoction].

Objective: To simultaneously determine the contents and explore the pharmacokinetics of ferulic acid and paeoniflorin by high performance liquid chromatography (HPLC) after oral administration of Modified Xiao-yao Decoction (MXYD), a compound of traditional Chinese herbal medicine.

Methods: A total of 8 healthy men were enlisted in this study. The serum samples were preprocessed by immersion method.
