[Analysis on follow-up efficacy and safety of slow transit constipation treated with individualized deep puncture at Tianshu (ST 25): a multi-central randomized controlled trial].

Objective: To evaluate the follow-up efficacy and safety on slow transit constipation (STC) treated with individualized deep puncture at Tianshu (ST 25).

Methods: One hundred and twenty-eight cases of STC were randomized into a deep puncture group (64 cases), a western medication group (31 cases) and a shallow puncture group (33 cases) at the ratio of 2:1:1. In the deep puncture group, electroacupuncture of deep puncture was applied to bilateral Tianshu (ST 25).

[Assessment of the operation standard and safety on the individual deep puncturing at Tianshu (ST 25) under CT].

Objective: To discuss the individual operation standard and safety on the deep puncturing at Tianshu (ST 25).

Methods: The deep insertion through the peritoneum about 1-2 millimeter was taken as individual standard depth at Tianshu (ST 25) for 39 patients. Using CT cross-section scanning and image surveying, the regression analysis was conducted on the impacts of abdominal circumference (AC,cm) to the peritoneum depth.

Ecological risk assessment of genetically modified crops based on cellular automata modeling.

The assessment of ecological risk in genetically modified (GM) biological systems is critically important for decision-making and public acceptance. Cellular automata (CA) provide a potential modeling and simulation framework for representing relationships and interspecies interactions both temporally and spatially. In this paper, a simple subsystem contains only four species: crop, target pest, non-target pest and enemy insect, and a three layer arrangement of LxL stochastic cellular automata with a periodic boundary were established.
