ABSTRACT
AIM: To investigate the change of long-term potentiation ( LTP ) , and the expression of 5-hydroxytryptamine 1A receptor (5-HT1A receptor) and postsynaptic density protein 95 (PSD-95) in the hippocampus of the rats with posttraumatic stress disorder (PTSD), and to explore the mechanism of 5-HT1A receptor in the regulation of spatial memory in the PTSD rats.METHODS:Healthy adult SD rats (n=36) were randomly divided into control group and mod-el group, with 18 rats in each group.The rats in model group were treated with single prolonged stress to construct the mod-el of PTSD.Morris water maze ( MWM) was used to test the learning and memory ability .The LTP induced by high-fre-quency stimulation (HFS) was detected by electrophysiological method .The protein expression of 5-HT1A receptor and PSD-95 in the hippocampus was determined by Western blot and immunofluorescence .RESULTS: The MWM analysis showed that the latency of the rats searching for the underwater platform in model group was significantly longer than that in control group (P<0.01).The results of electrophysiological analysis showed that the amplitude of the evoked potential in both groups were significantly increased after HFS in the hippocampus , but that in model group was significantly lower than that in control group (P<0.01).The results of Western blot and immunofluorescence analysis showed that compared with control group, the protein expression of 5-HT1A receptor was obviously increased (P<0.05), while the expression of PSD-95 was obviously decreased in model group (P<0.05).CONCLUSION:The spatial memory impairment in the PTSD rats may be associated with the increase in the expression of 5-HT1A receptor and the decrease in the expression of PSD-95 in the CA1 region of hippocampus .

ABSTRACT
Objective To explore the value of clinical features combined with 3-D reconstruction of multi-slice spiral CT in diagnosis of foreign body in trachea or bronchus in children. Methods The data of 52 children diagnosed of foreign body in trachea or bronchus were retrospectively reviewed. Both clinical features and 3-D reconstruction of multi-slice spiral CT were analyzed and summarized. Results In 52 children included ( 35 males and 17 females), 82 . 7%were under 3 years old. 30 children has repeated coughing and wheezing as the principal manifestation while 22 children presented with burst irritating and cough as primary manifestation. The main clinical signs were the asymmetry of pulmonary respiration ( 43 cases), wheeze ( 32 cases) and moist rale ( 29 cases). The positive rate of 3-D reconstruction of multi-slice spiral CT was 100%and consistent with the results of surgery. Among them, 5 cases were embedded in the trachea, 27 cases in the right bronchus, and 20 cases in the left bronchus. The main complications were emphysema ( 38 cases), bronchitis and pneumonia (32 cases), and pulmonary atelectasis (5 cases). Conclusion The combination of clinical features and 3-D reconstruction of multi-slice spiral CT can provide a reliable basis for the diagnosis of foreign body in trachea or bronchus in children.
ABSTRACT
Objective To investigate the effect of minocycline on the cognition and expressions of brain-derived neurotrophic factor (BDNF), apoptosis related factor Bcl-2 and Bax in hippocampus of rats with Alzheimer’s disease (AD). Methods The rat model was established by microinjection of Aβ25-35 into lateral ventricle. Thirty healthy male SD rats were randomly divided into three groups:control group, model group and minocycline treatment group. Normal saline 1 mL/(kg·d) was intraperitoneally injected in control group and model group. The minocycline treatment group was intraperitoneally injected with minocycline 50 mg/(kg · d) for 14 days. Morris water maze was used to detect the behaviors of animals. The expressions of BDNF, Bcl-2 and Bax in hippocampus were measured by Western blotting and enzyme linked immunosorbent assay (ELISA). The apoptosis of neurons was detected by TdT-mediated dUTP nick-end labeling (TUNEL). Results Minocycline greatly improved the behaviors of AD rats, up-regulated the expressions of BDNF and Bcl-2, and down-regulated the expression of Bax in hippocampus, and reduced cell apoptosis. Conclusion Minocycline plays a protective role in neural function by promoting the growth of neurons and inhibiting the neuronal apoptosis.
ABSTRACT
Objective To investigate the effects of low frequency repetitive transcranial magnetic stimulation (rTMS) applied to the supplementary motor area (SMA) of children with Tourette's syndrome (TS). Methods Thirty TS subjects less than 16 years old were treated with 1 Hz rTMS to the SMA at 110％ of the resting motor threshold (RMT) in 20 daily sessions,receiving 1200 pulses/day.Clinical assessment and physiological measures of the left and right RMT were conducted at different time points during the treatment. ResultsAfter 4 weeks of treatment,statistically significant reductions were observed in assessments with the Yale global tic severity scale (YGTSS) and in terms of clinical global impression (CGI).Symptomatic improvement was correlated with dramatic increases in both right and left RMTs. ConclusionApplication of 1 Hz rTMS to the SMA can improve the clinical symptoms of TS children.
