Study on the mechanisms of "Xiaoerhuashi Pill, XP" in intervening the health status of high-calorie diet animals.

Ethnopharmacological Relevance: "Xiaoerhuashi Pill, XP", with a history of 30 years in China, was included in the first part of the 2015 edition of the Chinese Pharmacopoeia and is widely used in the treatment for pediatric diseases in clinical application. Its main indications include the accumulation of heat caused by food stagnation in children, which has the effect of digestive stagnation and purge heat to relax the bowels.

Aim Of The Study: High-calorie diet, closely related to the occurrence and development of multiple diseases, is an unhealthy status of life.

BDNF Contributes to Spinal Long-Term Potentiation and Mechanical Hypersensitivity Via Fyn-Mediated Phosphorylation of NMDA Receptor GluN2B Subunit at Tyrosine 1472 in Rats Following Spinal Nerve Ligation.

Previously we have demonstrated that brain-derived neurotrophic factor (BDNF) contributes to spinal long-term potentiation (LTP) and pain hypersensitivity through activation of GluN2B-containing N-methyl-D-aspartate (GluN2B-NMDA) receptors in rats following spinal nerve ligation (SNL). However, the molecular mechanisms by which BDNF impacts upon GluN2B-NMDA receptors and spinal LTP still remain unclear. In this study, we first documented that Fyn kinase-mediated phosphorylation of GluN2B subunit at tyrosine 1472 (pGluN2B) was involved in BDNF-induced spinal LTP and pain hypersensitivity in intact rats.

[Professor Dong Gui-rong's experiences in treatment of child cerebral palsy].

According to the characteristics of the etiology and pathogenesis of child cerebral palsy, on the basis of "regulating the mind in treatment of all kinds of diseases" and "regulating the functions of five zang organs with back-shu points", Professor DONG Gui-rong applied the penetrating needling technique on the scalp points and acupuncture at back-shu points of five zang organs in the treatment of child cerebral palsy. The valuable clinical experiences have been summarized as "regulating the mind with scalp needling technique, benefiting the brain and opening the orifice", "regulating five zang organs with back-shu points" and "integration of acupuncture and rehabilitation, and function reconstruction". Two effective cases were introduced.

Palladium-catalyzed cyclocarbonylation of arynes with methyl allyl carbonates: selective synthesis of 1H-inden-1-ones.

A selective protocol for the synthesis of 2-methylene-3-substituted-2,3-dihydro-1H-inden-1-ones and 2-benzylidene-2,3-dihydro-1H-inden-1-ones has been developed via palladium-catalyzed cyclocarbonylation reactions of arynes with allyl carbonates and carbon monooxide (CO). It is noteworthy that the selectivity of this new route is depended on both substrates and ligands.
