Shock formation and structure in magnetic reconnection with a streaming flow.

The features of magnetic reconnection with a streaming flow have been investigated on the basis of compressible resistive magnetohydrodynamic (MHD) model. The super-Alfvenic streaming flow largely enhances magnetic reconnection. The maximum reconnection rate is almost four times larger with super-Alfvenic streaming flow than sub-Alfvénic streaming flow.

[Traditional Chinese medicine constitution types in 127 elderly patients with insomnia: an investigation in communities of Yangpu District, Shanghai].

Objective: To analyze the distribution of traditional Chinese medicine constitution types in elderly patients with insomnia.

Methods: The epidemiological data were collected from communities in the Yangpu District, Shanghai via a cross-sectional field survey. The elderly participants were enrolled by using the Pittsburgh Sleep Quality Index (PSQI) scale and the TCM Constitution Questionnaire.

[Effects of ursolic acid in ameliorating insulin resistance in liver of KKAy mice via peroxisome proliferator-activated receptors α and γ].

Objective: To explore the effects and mechanism of ursolic acid in improving hepatic insulin resistance in KKAy mice with spontaneous type 2 diabetes.

Methods: Thirty-five KKAy mice were divided into five groups according to the randomized block design, namely, control, rosiglitazone, fenofibrate, and high- and low-dose ursolic acid groups with seven mice in each group. C57BL/6J mice were used as the normal control group.

[Relationships between constitutional types of traditional Chinese medicine and motion sickness in 145 ocean sailors].

Objective: To investigate the relationships between constitutional types of traditional Chinese medicine (TCM) and motion sickness.

Methods: A survey of TCM constitutions in ocean sailors participating in a voyage was performed by using the TCM Constitution Questionnaire developed by Beijing University of Traditional Chinese Medicine, while the survey of motion sickness was operated by Graybiel's diagnostic criteria. The incidences of motion sickness among sailors with different types of constitutions were compared.
