New application of intestinal obstruction catheter in enterocutaneous fistula: A case report.

Background: Enterocutaneous fistula (ECF) is an abnormal connection between the gastrointestinal tract and the skin. ECF can lead to massive body fluid loss, hypercatabolism, and malnutrition. Therefore, nutritional support plays a crucial role in managing ECFs and promoting the healing of fistulas.

Data of ant community compositions and functional traits responding to land-use change at the local scale.

: Off-reserve conservation is a major contributor to China biodiversity conservation efforts, biodiversity conservation being achieved within afforestation and low-intensity agriculture in fragmented landscapes. Functional trait is more strongly related to ecological processes than taxonomic diversity and reflects ecosystem functioning and species responses to environmental changes. In this study, we selected five habitats that differ in degree of disturbance to explore the effects of land use on ant community compositions, traits distributions and functional diversity change.

Selective Fabrication of Single-Molecule Junctions by Interface Engineering.

Recent progress in addressing electrically driven single-molecule behaviors has opened up a path toward the controllable fabrication of molecular devices. Herein, the selective fabrication of single-molecule junctions is achieved by employing the external electric field. For molecular junctions with methylthio (-SMe), thioacetate (-SAc), amine (-NH ), and pyridyl (-PY), the evolution of their formation probabilities along with the electric field is extracted from the plateau analysis of individual single-molecule break junction traces.

[Effects of lac insect honeydew on the diversity of ground-dwelling ants in lac plantation].

By the method of pitfall trapping, an investigation was conducted on the diversity of ground-dwelling ants in a lac plantation in Yayi Town of Mojiang County, Yunnan Province of Southwest China in December 2009-May 2010, aimed to understand the effects of lac insect honeydew on the diversity of ground-dwelling ants. The presence or absence of lac insect honeydew and its dynamics all affected the species composition, abundance, and diversity of ground-dwelling ants. In the lac plantation with lac insect hosting, a total of 4953 ant individuals were collected, belonging to 34 species, 23 genera, and 5 subfamilies of Formicidae; whereas in the lac plantation without lac insect hosting, a total of 2416 ant individuals were collected, belonging to 30 species, 20 genera, and 5 subfamilies of Formicidae.

[Monopolization of honeydew sources by Crematogaster macaoensis and its effects on lac production].

From October 2008 to May 2010, an investigation was made in a lac plantation in Yayi region of Mojiang County, Yunnan Province, China, aimed to understand the behavior of the monopolization of honeydew sources by ant Crematogaster macaoensis, and its effects on the sex ratio, mortality, fecundity, and lac production of Yunnan lac insect Kerria yunnanensis. The results showed that C. macaoensis fed and monopolized the honeydews around the clock during the whole life cycle of K.

[Coexistence mechanism of ant community in lac plantation under habitat heterogeneity].

In order to reveal the coexistence mechanism of ant community in lac plantation, an investigation was made on the ant community composition and the ability of ant species in discovering and holding food resources in a lac plantation in Yayi Town of Mojiang County, Yunnan Province, with the relationships between ant body size and its ability of finding food under habitat heterogeneity probed. There were six dominant ant species in the plantation, i. e.
