Chinese Journal of Neurology 2011;44(8):524-527
Objective To explore memory function affected by chronic insomnia. Methods Fiftyfive patients with primary insomnia (PI), 119 patients with comorbidity of depression and insomnia (CDI)and 50 normal individuals were enrolled. Objective memories, including spatial working memory, spatial reference memory, objective working memory and object reference memory, were detected by nine boxes maze, and subjective memory was assessed by themselves on a 5-point scale ranging from 0 ( extremely severe problem) to 4 (no problem). Results Compared to the controls, the self-evaluated memory ( 1( 1,2 ) ) was worse in the mild PI patients, and the spatial working memory ( 6 ( 2. 5,11 ) ) was also worse in the severe PI patients( ×2 = 4. 526,3. 529, both P < 0. 01 ). For the CDI, the self-evaluated memory ( 2 ( 1,2) ) and spatial working memory (6(3,10)) were worse in the mild patients(×2 =5. 803,4. 155 ,both P <0. 01 ). However, the object ( 0. 5 (0,1) ) and spatial reference ( 1.5 ( 1, 3 ) ) memories were also worse in the severe patients ( ×2 =2. 641,3. 955 ,both P <0. 01 ). Conclusions PI damages subjective memory and the severe PI also damages spatial working memory. CDI damages various memory functions, especially in severe CDI patients, including subjective memory, object reference memory, spatial reference memory and spatial working memory.

Objective To explore whether an individual' s intention to gamble varied across different types of gambling. Methods A total of 373 Macau students completed a questionnaire survey on intention to gamble dealing with thirteen types of gambling,and exploratory factor analyses were conducted. Results The analyses showed two factors that had eigenvalues greater than one and explained a total of 59. 455 percent of the variance,with the largest factor explaining 32.59 percent. Participants' intentions to gamble were relatively lower in gambles of low counterparty with mean scores varying from ( 1.62 ± 1.13 ) to ( 2.20 ± 1.35 ), while the intentions were higher in gambles of high counterparty with mean scores varying from ( 2.34 ± 1. 39 ) to ( 3.02 ± 1.55 ). Conclusion Respondents' degree of intention to gamble was highly domain-specific, varying with the type of gambling.An individual' s intention to gamble is not consistent across all content domains, which implied that a potential gambler is not necessarily intended to gamble in all types of gambling.

Objective To summarize the distribution of departments,conditions of diagnosis and treatment of the syphilis patients in the general hospitals,and thus to improve the level of diagnosis and treatment.Methods A retrospective analysis of epidemiology and clinical data of 282 cases with syphilis in recent 5 years were conducted. Results The ratio of male to female was about 1:1.9.Female showed a high incidence in the 21 -50 years old,aver-age (41.68 ±0.96)years old,but for male in the 41 -70 years old,average (53.25 ±1.59)years old.The cases combined with other infectious diseases accounted to 22.0 % (62/282).The cases from the department of obstetrics and gynecology were the most (106 cases),followed by surgery (86 cases)and internal medicine (49 cases).Only 23 cases showed the clinical manifestations of syphilis in the 79 cases,which must be treated.The test rate of TRUST was only 39.0% (110/282).Furthermore,it was very low for the rate of treatment and standard treatment. Conclusion Syphilis is the most in department of obstetrics and gynecology in general hospital,and it is also com-mon in the surgery and internal medicine.The most prominent problems are that the non-special doctors had weak awareness for definite diagnosis of syphilis,and the low rate of treatment and standard treatment.
