Objective To study the comparability of two personality diagnostic instruments(SCID-Ⅱ and PDQ-4)in psychiatric patients. Methods One hundred and twelve mental disorder patients were investigated with the SCID-Ⅱ and PDQ-4. Results 1)Significant differences were found between groups(dividing by total scores on PDQ-4)by means of SCID-Ⅱ interviews(P＜0. 0 1). 2)Categorical personality disorder(PD)groups by means of SCID-Ⅱ interviews had hisher scores on PDQ-4 than their related non-PD groups. 3)For agreement on categorical diagnoses between SCID-Ⅱ and PDQ-4, the correlation coefficients varied from 0. 17 to 0. 57. Except for antisocial PD(r=0. 57), the others had poor-fair coefficients, as r＜0. 50. Conclusions In general, there is some correlation between SCID-Ⅱ and PDQ-4. Low agreement between PDQ-4 and SCID-Ⅱ is observed for categorical PD evaluations. Thus, PDQ-4 can't be a substitute tool for SCID-Ⅱ.

Objective To investigate the effect of isoflurane pretreatment on hypoxia/reoxygenation (H/R)-induced syndecan-1 shedding from human umbilical vein endothelial cells (HUVECs) . Methods HUVECs were cultured in EMB-2 medium and randomly divided into 3 groups ( n = 32 each) : control group (group C), H/R group and isoflurane pretreatment group (group I). H/R was produced by 4 h exposure of HUVECs to hypoxia followed by 2 h reoxygenation in H/R and I groups. HUVECs were exposed to the mixture of 5% CO2 and 95% O2 for 30 min and then cultured in normal culture atmosphere (21% O2) in group C. In group I, HUVECs were expased to 1.73% isoflurane and incubated for 30 min before H/R. The syndecan-1 expression, concentrations of shed syndecan-1 in the medium, and cell permeability and viability were measured at the end of reoxygenation. Results Compared with group C, the shed syndecan-1 concentration in the medium and cell permeability were significantly increased, while the syndecan-1 expression and cell viability decreased in H/R and Ⅰ groups ( P ＜ 0.01) . Compared with group H/R, the shed syndecan-1 concentration in the medium and cell permeability were significantly decreased, while the syndecan-1 expression and cell viability increased in group Ⅰ (P ＜ 0.01) . Conclusion Isoflurane pretreatment can protect HUVECs against H/R injury through inhibiting the syndecan-1 shedding.

AIM: To observe the effect of continuous epidural analgesia (CEA) of tramadol on postoperative gastrointestinal function and serum motilin level in the patients with cholecystectomy. METHODS: Twenty eight ASAⅠ-Ⅱpatients (8 male, 20 female) aged 24-56 yr, scheduled for elective cholecystectomy under epidural anesthesia, were randomly divided into tramadol group (T, n=14) and control group (C, n=14). The combination of tramadol 800 mg+ bupivacaine 150 mg+ droperidol 5 mg, which diluted with normal saline to 100 ml and pumped 2 ml?h -1, was administered in group T. The combination in group C was bupivacaine 150 mg+ droperidol 5 mg. The VAS values, the first anorectum exhaust timing (FAET), and the time of the first eliminating stool timing (FEST) were recorded, and serum motilin level measured with radioimmunoassay at the different times after surgery. RESULTS: There was a significant difference in the mean VAS values between group T ( 1.2? 1.2) and group C ( 3.3? 1.3) (P

Objective：To explore the distribution of personality disorder tendency of outpatients in psychological counseling departments.Methods：Systematic sampling was used to get the sample population from Shanghai Psychological Counseling Center.The Personality Diagnostic Questionnaire(PDQ~(+4))was administered to 1402 clients to screen personality disorders.Results：The subscales for different type of personality disorder(PD)and total score of PDQ~(+4) were higher than normal sample(e.g.total score of PDQ~(+4):client(38.23±17.04)vs.normal sample(22.79±14.10),P<0.001).The score of borderline subscales in female clients were higher than that of males [borderline:female(4.25±2.48)vs.male(3.97±2.41),P<0.05],the score of antisocial,paranoid and schizotypal subscales in male clients were higher than that of females [antisocial:female(1.31)vs.male(1.71),P<0.001;paranoid:female(2.75)vs.male(3.02),P<0.01;schizotypal:female(3.31)vs.male(3.56),P<0.05].Age stratification showed that the subscales for different type of PD of PDQ~(+4) were decreased with age [e.g.,total score of PDQ~(+4):18～24 years(41.73)vs.25～34 years(39.46)vs.35～44 years(33.88)vs.≥ 45 years(30.64),Ps<0.001],the positive rate of PDQ~(+4) subscales of obsessive-compulsive(58.5%)and avoidant PDs(54.0%)were higher than others,followed by borderline PD(44.4%).Factor analysis was used for the score of PDQ~(+4),factor 1 to 3 corresponded to cluster C,B and A personality disorders respectively,and the total variance explained 67%. Conclusion：There are different rates of personality deviation between psychological counseling clients and normal sample in China.Some traits of personality disorders can be improved with the increasing of age.The abstracted factors by factor analysis are very consistent with what originally proposed in the theory of personality disorder.It should be paid attention to PD tendency of clients during psychological counseling.

Spinal anesthesia with advantages of easy operation, fast effect and small maternal and neonatal effects has always been the preferred anes?thetic technique for cesarean section in China. However, maternal hypotension induced by spinal anesthesia remain a large challenge for anaesthetist. Perioperative fluid management plays important roles in maintaining maternal and fetal hemodynamics. This review mainly analyzes pathophysiological mechanism of maternal hypotension induced by spinal anesthesia,introduces different fluid?management strategy and functions on prevention of maternal hypotension.
