Measurement Properties of the Simplified Chinese Version of the Lumbar Spine Instability Questionnaire for Patients With Low Back Pain in Mainland China.

Study Design: A prospective study.

Objective: To develop a simplified Chinese version of Lumbar Spine Instability Questionnaire (SC-LSIQ) and test its measurement properties.

Summary Of Background Data: The LSIQ has been translated into several languages.

Synthesis of a new water-soluble hexacarboxylated tribenzotriquinacene derivative and its competitive host-guest interaction for drug delivery.

A new water-soluble hexacarboxylated tribenzotriquinacene derivative () was synthesized and used as a supramolecular drug carrier to load the model anticancer drugs dimethyl viologen () and doxorubicin () via host-guest interactions. The drugs could be effectively released by spermine (), a molecule overexpressed in cancer cells, through host-guest competitive substitution since has a stronger binding affinity toward than and . The host-guest interactions of the complexes of with , and were investigated by NMR spectroscopy and fluorescence spectroscopy.

Water-soluble host-guest complexes between fullerenes and a sugar-functionalized tribenzotriquinacene assembling to microspheres.

A sugar-functionalized water-soluble tribenzotriquinacene derivative bearing six glucose residues, , was synthesized and its interaction with C and C-fullerene in co-organic solvents and aqueous solution was investigated by fluorescence spectroscopy and ultraviolet-visible spectroscopy. The association stoichiometry of the complexes with C and with C was found to be 1:1 with binding constants of = (1.50 ± 0.

New eudesmane sesquiterpenes from Alpinia oxyphylla and determination of their inhibitory effects on microglia.

The fruits of Alpinia oxyphylla are used as healthcare products for the protection on neurons and prevention of dementia. Two new noreudesmane sesquiterpenoids, (5R,7S,10S)-5-hydroxy-13-noreudesma-3-en-2,11-dione (1) and (10R)-13-noreudesma-4,6-dien-3,11-dione (2), and a new eudesmane sesquiterpenoid, (5S,8R,10R)-2-oxoeudesma-3,7(11)-dien-12,8-olide (3), as well as 12 known sesquiterpenoids, were isolated from the fruits of A. oxyphylla.
