Objective To evaluate the effects of selective serotonin reuptake inhibitors (SSRIs) on sleep apneas in Sprague-Dawley (SD) rats.Methods Thirty adult male SD rats were randomly divided into two groups (15 rats in each group).The treatment group and the control group were injected intraperitoneally with paroxetine (10 mg · kg-1·d-1) and sterile distilled water (2 mL · kg-1 · d-1) for 7 days respectively.Parameters about sleep apnea and sleep structure were measured before and after the treatment.Results In the treatment group, there was a significant reduction of apnea index (AI) from (12.4±3.7) times/hour to (7.4±2.2) tmes/hour (P = 0.000).Both post sigh apnea index (PSAI) and spontaneous apnea index (SPAI) were decreased significantly (P = 0.000 and 0.021 respectively) in non-rapid eye movement (NREM) sleep, but not in REM sleep.REM sleep was reduced from 8.6% to 8.0% (P = 0.013) and its latency was increased from (54.1±48.4) rain to (110.9±43.4) min (P = 0.001) in the treatment group,as well as the sleep-onset latency [from (20.7±9.1) rain to (30.0±15.7) rain, P = 0.038].Conclusion Paroxetine can reduce sleep apneas in SD rats during NREM sleep.Its effects on sleep structure include reducing REM time,increasing REM latency and sleep-onset latency.

Objective: To study the gender differences in ERPs recorded during a recognition task for Chinese words. Methods: 15 male and 15 female healthy volunteers received a Chinese words recognition task and the EEG signals were recorded from 20 scalp sites simultaneously. The stimuli were meaningful words consisting of two Chinese characters. Results: Both men and females showed a positive-going parietal old/new effect, but females demonstrated larger P500 amplitudes and shorter P500 latency than males. Furthermore, the parietal old/new effect of males was significantly left-lateralized, while that of females showed more bilateral pattern. Only males elicited obvious frontally distributed old/new effect between 250 and 350 ms, which was negative-going and right-lateralized. Conclusion: Gender differences do exist in the recognition processing of Chinese words. Some of the gender differences could be interpreted as reflecting different strengths and speed of brain activation and others could be interpreted as reflecting the involvement of different neural structures.

Objective To evaluate the role of membrane-bound complement regulatory protein expression in spinal cord dorsal horn in the development of neuropathic pain (NP) in rats.Methods Forty-eight male Sprague-Dawley rats,weighing 200-250 g,in which intrathecal catheters were successfully implanted without complications,were randomly divided into 4 groups (n =12 each):sham operation group (group S),group NP,normal saline group (group NS) and minocycline group (group M).NP was induced by chronic constrictive injury of the sciatic nerve in NP,NS and M groups.Minocycline 50 μg was injected intrathecally once a day for 7 consecutive days starting from 1 day before ligation of the sciatic nerve in M group,while the equal volume of normal saline was given in stead of minocycline in NS group.Mechanical pain threshold and thermal pain threshold were measured at 1 day before ligation of the sciatic nerve (baseline,T0) and 1,3,7 days after ligation of the sciatic nerve (T1-3).Then the rats were sacrificed at T3 and the lumbar segment (L4,5) of spinal cord was removed for determination of the expression of CD46,CD55,CD59 protein and mRNA in the dorsal horn of spinal cord by Western-blot and RT-PCR,respectively.Results Compared with S group,mechanical pain threshold and thermal pain threshold were significantly decreased at T1-3 and the expression of CD46,CD55 and CD59 protein and RNA was down-regulated at T3 in NP,NS and M groups (P < 0.05).Compared with groups NS and NP,mechanical pain threshold and thermal pain threshold were significantly increased at T2.3 and the expression of CD46,CD55 and CD59 protein and RNA was up-regulated at T3 in M group (P < 0.05).Conclusion The down-regulated expression of membrane-bound complement regulatory proteins in spinal cord dorsal horn and abnormal activation of the complement are involved in the development of NP in rats.
