Objective To compare the effect of clustered acupuncture of the scalp combined with constraint induced movement therapy (CIMT) with that of conventional acupuncture of the body points plus conventional rehabilitation intervention after cerebral infarction using blood oxygenation level dependent functional magnetic resonance imaging (BOLD-fMRI).Methods Thirty acute cerebral infarction patients with hemiplegia were equally divided into two groups at random.The test group received the clustered acupuncture of the scalp combined with CIMT,while the control group received the body point acupuncture plus conventional rehabilitation intervention.Before and after two weeks of treatment,blood oxygenation level-dependent functional magnetic resonance imaging at 3.0 T was performed during a passive digital opposition movement.The volume and intensity of the activated areas were compared.Fugl-Meyer assessment (FMA) was carried out as well.Results The most pronounced activation appeared in the contralateral somatosensory motor cortex for both groups.There was no significant difference in average FMA scores between the two groups before the treatment,but after the treatment the averages were significantly different.An increase in activated volume and intensity in the contralateral SMC was observed in both groups after the treatment,but the test group showed a much larger change in both activated volume and intensity.Conclusion The clustered acupuncture of the scalp combined with CIMT can achieve a more significant improvement in functional recovery after acute cerebral infarction than conventional acupuncture of the body points plus conventional rehabilitation intervention.Such combined therapy is worthy of application in clinical practice.

Objective To establish a method to compare the difference of exposure component of oral taking different part ofPueraria Lobata (Willd.) Ohwi in intestine.Methods After the incubation of puerarin,extraction Radix Puerariae and Flos Puerariae with S9,the mixtures were centrifuged to get the supernatant for analysis with HPLC.Results The research showed that the metabolic rate of puerarin was higher than that of extractions because of the concentration of enzyme.The difference between the fingerprints of Radix Puerariae and Flos Puerariae Lobata indicated that there was a difference of chemical components in such two parts of Kudzuvine Root.Conclusion The profile of intestinal metabolism can be revealed in the research of gut wall metabolism in the course of intestinal absorption by S9 incubation.

Objective The alm of this study was to determine the solubility and permeability of daldzin and daldzein and the interaction of these two components.Methods With the method inChinese Pharmacopoeia and in situ single-pass intestinal perfusion model we tested the solubility and permeability of daldzin, daldzein and their interaction.Results In pH 7.4 K-R buffer the solubility of daldzin was 6 times than daldzein and both the solubility of these two components were enhanced when they were determined together. In small intestine of rat, the permeability of daldzein was 3 times than daldzin. Daldzin could enhance the permeability of daldzein but the daldzein manifested an opposite trend.Conclusion When compared to daldzin, daldzein owned a lower solubility but a better permeability. When used together, both the solubility and permeability of daldzein would be enhanced. The solubility of daldzin could be enhanced slightly but its permeability would be reduced.

Objective To research the metabolism and distribution ofsilybin in normal rats and liver injury model rats.Methods The normal rats group and immunity liver injury rat models were fed with the same dose ofsilybin capsule,and HPLC was used to determine the silybin concentration in biological samples in different time.Results The silybin concentration in the normal group in biological samples was higher than the model group at different time.In the normal group,the consequence of silybin concentration in each viscera distribution from top to bottom was liver＞kidneys＞plasma＞heart,while in the model group the fact was kidneys＞heart＞liver＞plasma.Conclusion The difference of metabolism and distribution of silybin in normal rats and liver damage model rats was obvious.

Objective To compare the dissolution of Chuangxiong powder in different medium and discuss the dissolution characteristics in vitro of Changxiong powder. Methods The paddle method was adopted, the UV spectrophotometric method was developed to determine the in vitro dissolution quantity of Changxiong powder in five medium (water, 0.1 mol/L hydrochloric acid, acetate buffer of pH 4.5, phosphate buffer of pH 6.8, phosphate buffer of pH 7.4) with ferulic acid as index, and evaluated by drawing the dissolution curve and using the similar factor method and Weibull model. Results The dissolution quantity of Changxiong oral powder in five medium was different. The dissolution quantity in water, 0.1 mol/L hydrochloric acid, acetate buffer of pH 4.5 and phosphate buffer of pH 6.8 was similar and fit Weibull model, but it mutated in phosphate buffer of pH 7.4 and reached the maximum amount at 30 min. Conclusion The dissolution quantity of Changxiong powder is gradually increasing and the time is shorted in the medium from acidic to neutral then to alkaline. Dissolution curve is similar in the acidic and neutral medium. Changxiong powder dissolves out fast and completely in the alkaline medium.

Objective:To explore the different functional connectivity of right caudate nucleus between adults with high myopia and normal vision controls.Methods:The resting-state functional magnetic resonance imaging(fMRI) data were collected from twenty-five high myopia(HM group) and twenty-seven normal vision subjects(NC group). Right caudate nucleus and their subregions(anterior and posterior subregions included) were used as seeds to perform seed-based functional connectivity (FC)analyses at group level under three different frequency bands: convention (0.010~0.080 Hz), slow-5(0.010~0.027 Hz) and slow-4(0.027~0.073 Hz).Results:(1)Compared with NC group, FC of right caudate nucleus with left middle occipital gyrus(MNI: x=-48, y=-84, z=9), left fusiform gyrus(MNI: x=-30, y=-63, z=-12), and right middle frontal gyrus(MNI: x=39, y=12, z=39) were stronger in HM group(all P<0.05, Alphasim Corrected). (2)In HM group, these changed FC were mainly detected in the anterior subregion of right caudate nucleus.(3)The increased FC of right caudate nucleus and its anterior subregion with left middle occipital in HM group were mainly reflected in the frequency band of slow-4(all P<0.05, Alphasim Corrected). Conclusion:The right caudate nucleus in adults with high myopia may play compensatory roles in visual perception and visual attention by enhancing its functional connectivity with visual and visual attentional brain areas.
