Research on volatile components of gualou guizhi decoction and its components in rat brain by GC-MS / 中国中药杂志

To investigate the role of volatile components in the compound and to find the substance foundation of Gualou Guizhi decoction (GLGZD) for curing extremities spasticity after stroke. The chemical compositions of essential oil, obtained by hydrodistillation from Gualou Guizhi decoction and its major constituting herbs (Trichosanthis Radix, Paeoniae Alba Radix, Cinnamomi Ramulus, Zingiberis Recens Rhizoma, Glycyrrhizae Radix, Ziziphi Jujubae Fructus) were analyzed by GC-MS to evaluate the correlativity between volatile components of GLGZD and its major constituting herbs, and volatile components after oral administration of GLGZD in the rats' brain. Volatile components of GLGZD are mainly derived from Cinnamomi Ramulus, Zingiberis Recens Rhizoma, Ziziphi Jujubae Fructus, Trichosanthis Radix. The volatile components in the brain is mostly derived from radix trichosanthis. Compared with individual herbs of GLGZD, the dissolution of the components increase or new components appear after compatibility of six herbs. Adminstrated with GLGZD, the results point out that volatile components in the brain play a neuroprotective role through passing the brain.

Attention networks in patients with Parkinson' s disease / 中华神经科杂志

Objective To investigate the characteristics of attention networks impairment in Parkinson' s disease patients.Methods Attention network test was performed in 28 PD patients and 28 normal controls on the efficiency of three anatomically defined attentional networks:alerting,orienting,and executive control.Results The correct rate of attention network test was significantly lower(P0.05).The relative analysis showed that the Hoehn Yahr stage was positively correlated with the value of executive netwok(r=0.794,P
