Effect of Acupuncture Cooperated with Low-frequency Repetitive Transcranial Magnetic Stimulation on Chronic Insomnia:A Randomized Clinical Trial / 华中科技大学学报（医学）（英德文版）

The effect of acupuncture cooperated with low-frequency repetitive transcranial magnetic stimulation (rTMS) on chronic insomnia was explored.Seventy-eight patients with chronic insomnia were randomly allocated into two groups:treatment group and control group.In the treatment group,the patients received acupuncture combined with rTMS treatment,and those in the control group were given acupuncture cooperated with sham rTMS treatment,3 days per week for 4 weeks.Before and after treatment,the primary outcomes including the scores on Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI) and the secondary outcomes including total sleep time (TST),sleep onset latency (SOL),wake after sleep onset (WASO),sleep efficiency (SE％) recorded by sleeping diary and actigraphy were observed in both groups.Seventy-five participants finished the study (38 in treatment group and 37 in control group respectively).After treatment,the scores in the two groups were improved significantly,more significantly in the treatment group than in the control group.It can be inferred that acupuncture cooperated with rTMS can effectively improve sleep quality,enhance the quality of life of patients and has less side effects.

Effects of Angelica sinensis treatment on the expression of flt-1 and flk-1 mRNA after the ischemic brain injury in rats / 中国应用生理学杂志

<p><b>AIM</b>To investigate the effects of Angelica sinensis on the expression of Flt-1, Flk-1 mRNA after the ischemic brain injury in rats.</p><p><b>METHODS</b>Wistar rats randomly divided into two groups: group A rats underwent middle cerebral artery occlusion (MCAO) for 2 hours by suture, group B rats underwent MCAO for 2 hours meanwhile received treatment with Angelica sinensis (5g/kg). At 1 st d, 3 rd d and 7 th d after reperfusion, 36 rats( n = 18 in each group) were assessed by neurological scale and brain tissue was taken to assess the lesion ration with 2, 3, 5-triphenyltetrazolium chloride (TTC) staining. The other rats (n = 3 at different time points in each group) were decapitated at 3 h, 6 h, 12 h , 1 st d, 3 rd d, 7 th d after reperfusion. Quantitative reverse transcription and polymerase chain reaction (RT-PCR) technique was used to examine the gene expression of Flt-1, Flk-1.</p><p><b>RESULTS</b>The neurologic deficit score of rats in group B decreased significantly compared with group A at the same time point (P < 0.05). The infarct volume of group A was significant greater than group B at the same time point after reperfusion (P < 0.01). The results of RT-PCR revealed that the gene expression of Flt-1, Flk-1 in the two groups increased from 3 h after reperfusion and reached its peak at the time of 3 rd d after reperfusion, then declined gradually. The gene expression of Flt-1, Flk-1 in the group B was significantly increased than group A at the same time point (P < 0.01). The gene expression of Flk-1 was positive correlated with Flt-1 in two groups (r = 0.957).</p><p><b>CONCLUSION</b>The increasing amount of Flt-1, Flk-1 expression was enhanced by Angelica sinensis following transient interruption of cerebral blood flow in rats.</p>

Effects of Angelica sinensis injection on the neuronal metabolites and blood flow speed within reperfusion following the ischemic cerebral injury in rats / 中国应用生理学杂志

<p><b>AIM</b>To investigate the effects of Angelica sinensis injection on the neuronal metabolites and blood flow speed within reperfusion in the ischemic cerebral injury of rats.</p><p><b>METHODS</b>Sixty-nine male Sprague Dawley rats with an average body weight of 150 to 170 g were used, and were randomly divided into three groups: sham operation group (n = 4), ischemia injury group (n = 30) underwent an operation of ischemic brain injury, Angelica-treated group (n = 35) underwent the same operation and received the treatment of Angelica sinensis injection (5 g/kg bw, i. p). The right middle cerebral artery occlusion (MCAO) of both ischemia injury group and Angelica-treated group rats was induced by 5/0 nylon suture for 2 hours. The reperfusion was conducted for three to four hours and five to six hours respectively following MCAO. T2 weighted-imaging (T2WI) and 1H magnetic resonance spectroscopy (1H MRS) were performed, to study the changes in imaging and neuronal metabolites N-acetyl aspartate (NAA), creatine/phosphocreatine (Cr/ PCr) and choline (Cho) following cerebral ischemia. The changes in blood flow speed were measured by laser Doppler flowmetry. The surface vascular density in right hemisphere were calculated.</p><p><b>RESULTS</b>The hyperintense signals and volume in the right cerebrum in Angelica-treated group decreased compared with those of the ischemia injury group, the T2 values were decreased, and the level of NAA increased, the ratio of Cr/NAA and Cho/NAA decreased. The blood flow speed in Angelica-treated group was improved. The length of brain surface vessels in group C increased.</p><p><b>CONCLUSION</b>The Angelica sinensis injection enhanced the blood circulation in the ischemic brain, improved the neuronal metabolisms.</p>

<p><b>OBJECTIVE</b>To investigate the effects of Erigeron breviscapus preparation on the imaging and neuronal metabolites after reperfusion in the ischemic cerebral injury in rats.</p><p><b>METHOD</b>Twenty-three male Sprague Dawley rats with an average body weight of (165 +/- 15) g (mean +/- S) were used, and were randomly divided into two groups: group A rats (n = 11) underwent an operation of ischemic brain injury, group B rats (n = 12) underwent the same operation and received the treatment of Erigeron breviscapus preparation (1.5 mg.kg-1 weight, i.p.). The right middle cerebral artery occlusion (MCAO) of rats in both groups was induced by 5/0 nylon suture for 2 hours.
