Objective To explore the relationship between predictable ocular motor control and cognitive function in Parkinson's disease(PD). Methods Videonystagmography was used to examine 24 patients with idiopathic PD(PD group) and 24 healthy controls(control group) on predictable ocular motor control.The accuracies of saccade were compared between two groups.The correlation among accuracy for predictive saccade(latency

Objective To compare the difference of early trauma experience between early-onset and late-onset obsessive-compulsive disorder(OCD),and the kinds of early trauma in the cause of OCD. Methods Three hundred and twenty-six patients with obsessive-compulsive disorder and 480 healthy con-trols were enrolled. Early Trauma Inventory-Short Form ( ETI-SF) was applied to assess the early trauma ex-perience,compare the difference of early trauma experience between early-onset ( n=138) and late-onset ( n=188) OCD,and the kinds of early trauma in the cause of OCD. Results There were significant differences in the early trauma experience between obsessive-compulsive disorder group and control group((3.90±3.61) vs (1.88±2.61), P<0.01).Scores of physical((1.12±1.38) vs (0.71±1.23), P=0.001),emotional((1.58± 1.71) vs (0.42±1.01), P<0.01),and sexual abuse((0.27±0.59) vs (0.09±0.36), P=0.001),and a gener-al traumatic experience((0.94±1.17) vs (0.66±1.09), P<0.01) were significant difference between patients and controls. Except sexual abuse((0.30±0.66) vs (0.24±0.67), P=0.42),there were significant differ-ences in the early trauma between early-onset and late-onset OCD((5.12±3.58) vs (3.01±3.38), P<0.01), especially emotional abuse((2.18±1.76) vs (1.12±1.53), P<0.01).247(75.8%) OCD patients and 79(57. 9%) healthy controls experienced early trauma(χ2=21.48, P<0.01). Experiencing one kind of early trau-ma,the prevalence of OCD was 39.1%,two kind was 61.0%,three kind of early trauma was 65.8%,and ex-periencing four or more kind of early trauma,the prevalence of OCD was up to 84.4%. Conclusion OCD patients have much more early trauma,especially early-onset OCD. Experiencing more kind of early trauma, and the prevalence of OCD higher may associated with the development of obsessive-compulsive disorder. It is important to consider the role of childhood trauma in the prevention and treatment of OCD.

A series of quinoline-polyamine conjugates (8a-8n) were designed, synthesized and evaluated as inhibitors of cholinesterases (ChEs). Some of these compounds had potent ChEs inhibitory activity with IC50 values at micromolar range. Compound 8n exhibited the strongest inhibition on acetylcholinesterase (AChE) with an IC50 value of 8.78 micromol x L(-1), and compound 8i showed the most potent inhibition on butyrylcholinesterase (BChE) with IC50 value of 1.60 micromol x L(-1) which was slightly better than rivastigmine. The structure-activity relationship revealed that the chain length of polyamine and linker played important roles for inhibitory activity. Molecular modeling studies showed that 8i targeted both the catalytic active site (CAS) and the peripheral anionic site (PAS) of cholinesterases.

To investigate the effects of particle size, mPEG molecular weight, coating density and zeta potential of monomethoxyl poly(ethylene glycol)-poly(lactic-co-glycolic acid) (mPEG-PLGA) nanoparticles on their transportation across the rat nasal mucosa, mPEG-PLGA-NPs with different mPEG molecular weights (M(r) 1 000, 2 000) and coating density (0, 5%, 10%, 15%) and chitosan coated PLGA-NP, which loaded coumarin-6 as fluorescent marker, were prepared with the nanoprecipitation method and emulsion-solvent evaporation method, and determine their particle size, zeta potential, the efficiency of fluorescent labeling, in vitro leakage rate and the stability with the lysozyme were determined. The effects of physical and chemical properties on the transmucosal transport of the fluorescent nanoparticles were investigated by confocal laser scanning microscopy (CLSM). The result showed that the size of nanoparticles prepared with nanoprecipitation method varied between 120 and 200 nm; the size of nanoparticles prepared with emulsion-solvent evaporation method varied between 420 and 450 nm. Nanoparticles dispersed uniformly; the zeta potential of PLGA-NPs was negative; mPEG-PLGA-NPs was close to neutral; chitosan coated PLGA-NPs was positive; and the efficiency of fluorescent labeling were higher than 80%. In vitro leak was less than 5% within 4 h and nanoparticles were basically stable with lysozyme. The CLSM results show that the transportation efficiency of mPEG-PLGA-NPs with a high PEG coating density and high mPEG molecular weight was significantly higher than that of uncoated PLGA nanoparticles and also that of chitosan coated PLGA-NPs (P < 0.05). The hydrophilcity, zeta potential and particle size of nanoparticles play important roles on the efficiency of mPEG-PLGA nanoparticles to transport across the rat nasal mucosa.

Methods(The model) of focal cerebral ischemia was built by middle cerebral artery occlusion.Immunocytochemistry staining was used to observe the dynamic changes of Trk expression at different time of acute stage of ischemia,and the patterns at different regions of the striate and hippocampal were detected. Results Trk immuno-positive neurons widely expressed in the normal brain.The number of Trk immuno-positive neurons was decreased abruptly in the necrosis core of the focal cerebral of ischemia,while increased obviously in the penumbra region and the DG area after 6 h of occlusion(P
