Objective To describe clinical features,polysomnographic (PSG) alterations and characteristics of motor and distribution during rapid eye movement (REM) sleep in narcoleptic patients with REM sleep behavior disorder (RBD).Methods We retrospectively summarized general features of 22 narcoleptic patients with RBD,96 narcoleptic patients without RBD and 21 healthy subjects as controls.We compared their PSG and the related indexes in 3 groups.Then we analyzed a full-night video-PSG recording in a continuous series in 22 narcoleptic patients with RBD to identify their motor behavior and distribution features.Results There was no significant difference in PSG parameter and correlation index between the narcoleptic patients with RBD group and without RBD group.However,compared with normal control group (20.15 ± 4.52),narcoleptic patients with or without RBD (24.07 ± 5.44,23.40 ± 4.50) showed increased the body mass index(F =4.869,P =0.009),shortened NREM sleep and REM sleep (min) latency at night (4.41 ±7.01,3.55 ±3.98 and 14.69 ±9.62,x2 =31.697,P =0.000;69.39 ±81.39,71.04 ±74.45and 115.31 ± 45.13,x2 =11.485,P =0.003),increased percentage of sleep stage 1,decreased percentage of slow wave sleep,delayed the arousal time and increased number of arousal episode longer than 5 minutes.In narcoleptic patients with RBD,RBD episodes occurred frequentlyatany stage of REM sleep through whole night and the frequency of vocalizations did not significantly differ between the two halves of the night.Pantomimes were significantly more frequent in RBD episodes of the second half of the night.Conclusions The prevalence of RBD is high in narcoleptic patients.Sleep architecture doesn' t differ between narcoleptic patients with and without RBD.There is no correlation between the occurrence of RBD and narcoleptic duration.In narcoleptic patients with RBD,vocalizations and pantomimes accounted formajor proportion of RBD episodes while aggressive-violent movements are rare.

Objective To explore the expression and function of galanin and its receptor in the female mice of anxiety-and depression-like behavior.Methods In situ hybridization was used to detect the expression of galanin,GalR1,GalR2 and GalR3 in the hippocampus of C57BL/6J female mice.A total of thirty female mice was divided into two groups:experiment group (n=15) and control group (n=15).The experiment group was subjected to the chronic unpredictable mild stress (CUMS) for four weeks,and the control group was not subjected to any treatment.Four weeks later,a series of tests were performed on those two groups,including the sucrose preference test,the novel object recognition test,the open field test and suspension tail test.After behavior tests,the hippocampus RNA was extracted from eight mice in each group to test the expression of galanin and its receptor through qPCR.The rest part of mice were used to mark C-Fos immunostaining in the dentate gyms (DG) of hippocampus.Results The result of in situ hybridization showed that galanin,GalR1 and GalR2 distributed in the Hillus of ventral hippocamous,GalR3 had no positive signal.In the sucrose preference test,the experiment group drunk less sucrose when compared with the control group (P＜0.05).In the novel object recognition test,the experiment group contacted shorter time to the novel object when compared with the control group (P＜0.05).In the open field test,the experiment group had shorter in session time when compared with the control group (P＜0.05).In the suspension tail test,the experiment group had longer immobility time when compared with the control group (P＜0.05).The qPCR result showed that the higher expression of galanin and GalR1 in the hippocampus of experiment group (P＜0.05).More C-Fos positive cells in the DG of hippocampus of experiment mice were immunostained (P＜0.05).Conclusions Galanin,GalR1 and GalR2 mainly distribute in the Hillus of the ventral hippocampus.Galanin may be involved in the anxiety-and depression-like behavior of C57BL/6J through GalR1.

Most α2-AR agonists derived from dexme-detomidine have few structure differences between them and have no selectivity for α2A/2B-AR or Gi/Gs,that can lead to the side effect of drugs.To get novel and potent α2A-AR agonists,we built the homology model for human α 2A-AR and α2B-AR to find α2A-AR agonists with higher selectivity.Compound P300-2342 and its 3 analogs sig-nificantly decreased the locomotor activity of mice(P＜0.05).Furthermore,P300-2342 and its 3 analogs inhibited the binding of[3H]rauwolscine to α 2A-AR and α 2B-AR respectively.In α2A-AR-HEK293 cells,P300-2342 decre-ased forskolinstimulatedcAMPpruductionwithoutincreas-ing cAMP pruduction,that indicated the P300-2342 acti-vating α2A-AR coupling with Gαi/o pathway without Gαs coupling.P300-2342 had no agonistic and antagonistic activities on α 2B-AR.Similar results were shown in 3 analogs of P300-2342.The docking results showed that P300-2342 formed the π-hydrogen bonds with Y394,V114 of α2A-AR,and with V93 of α2B-AR.3 analogs of P300-2342 formed several π-hydrogen bonds with V114,Y196,F390 of α 2A-AR and with V93 of α 2B-AR.We believe that these molecules can serve as leads for fur-ther optimization of α2A-AR agonists with potentially few side effects.

The correlation between transient receptor potential vanilloid-1 (TRPV1) receptor and peripheral nervous system diseases has been confirmed. In recent years, studies have shown that TRPV1 plays an important role in the central nervous system; its wide distribution in the hippocampus, cortex, and midbrain bridges the correlation between TRPV1 receptor and cognitive learning and memorial function. This paper reviews the biological role of TRPV1 receptor in the nervous system at home and abroad and concludes the relations of TRPV1 receptor with cognitive associated diseases, aiming at providing theory basis for whether TRPV1 receptors can be used as therapeutic drug targets for cognitive associated diseases.
