Objective: To investigate the effect and mechanism of Sibiraea angustata on lipid metabolism in hight-fatted SD rats.
Methods: After the obese model was built,Sibiraea angustata was administrated intragastrically to obese rats for 8 weeks. Peeled off fat around kidneys and made pathological tissue sections. The number and size of adipocytes were detected. The levels of adiponectin, adipoR2, AMPK, and PPARgamma mRNA in adipose tissue were detected by RT-PCR. AMPK protein expression in adipose tissue were detected by Western Blot.
Results: Compared with the model group, the diameter of adipocytes were reduced while the number increased after adminiseration of Sibiraea angustata for 8 weeks. The levels of adiponectin, adipoR2, AMPK and PPARgamma mRNA were increased siginficantly. The expression of AMPK protein was also up-regulated significantly.
Conclusion: Sibiraea angustata has anti-obesity effect. The mechanism may be related to the adiponectin signal transduction pathway.

How Tibetan red deer () acclimates to high altitude environment during the withered grass period is one of the challenges in maintaining their nutrient intake. It is an important basis to study the nutritional ecology of wild large ungulates in alpine ecosystems by investigating the changes in plant communities with altitude during the withered grass period and how these changes affect the food composition of Tibetan red deer. In this study, we selected the Tibetan red deer in Sangri County, Shannan region of Tibet as the research subject.

In this work, a novel strategy was developed for separation and enrichment of sibiskoside by dummy molecular imprinting technology and magnetic separation technology. The structural analogue geniposide was selected as the dummy template, using 4-vinylpyridine as the functional monomer, ethylene glycol dimethacrylate as the cross-linking agent, and acetonitrile as the porogen. The molecularly imprinted layer was formed on the surface of the magnetic carrier to prepare dummy template molecularly imprinted polymers (DMIPs) with a core-shell structure.

We investigated the effects of warming on soil nitrogen cycling process in alpine scrub ecosystem, with an simulated warming experiment at alpine scrubland on the eastern Qinghai-Tibet Plateau, China. We examined the responses of soil nitrogen transformation rate to warming in three critical periods (the early, late, and non-growing seasons). The results showed that warming increased soil temperature by 1.
