Objective To investigate the association between early trauma experiences and obsessivecompulsive disorder (OCD). Methods One hundred and eighty-five patients who met with OCD diagnosis of DSM-Ⅳ and one hundred and thirty-two healthy controls were recruited. Early trauma experience of all participants was assessed with Early Trauma Inventory-Short Form (ETI-SF) ,and severity of symptoms of OCD patients was evaluated with Yale-Brown Obsessive-Compulsive Severity Scale (Y-BOCS). Results When compared with controls, OCD group showed significantly higher in ETI-SF total score (3.55 ± 3.29 vs 1.51 ± 1.98, P ＜ 0. 01 ) and had greater in general trauma (0.89 ± 1.10 vs 0. 43 ±0.77, P＜0.01 ) ,physical abuse (0.98 ± 1.31 vs 0.65 ±1.04, P=0. 016),emotional abuse(1.43 ±1.61 vs 0.38 ±0.89, P＜0. 01),and sexual abuse(0.24 ±0.59 vs 0.06 ±0.30, P＜0. 01 ). Female OCD patients reported more sexual abuse than male patients(0.33 ±0.69 vs0. 16 ± 0.45, P = 0.049) . There was a negative correlation between onset age of obsessive symptoms and early trauma experiences(P ＜ 0. 01 ), except sexual abuse experiences (P = 0. 10). Conclusion OCD patients have much more childhood traumas, and the more trauma experiences are,the earlier onset of OCD is, which may associated with the development of obsessive-compulsive disorder.

Objective To understand the occurrence of catheter-associated urinary tract infection(CAUTI)in pa-tients with catheterization,and provide evidence for reducing the incidence of CAUTI.Methods Based on monito-ring requirement for CAUTI in competency building project of healthcare-associated infection(HAI)prevention and control established by Hospital Infection Management Committee of Chinese Hospital Association,CAUTI among patients who hospitalized and received urinary catheterization ≥2 days in a hospital from January to December 2014 were analyzed prospectively,incidences of CAUTI in different patients were compared.Results A total of 6 046 patients with urinary catheterization were monitored,166 of whom developed CAUTI,incidence of CAUTI was 2.75%,the total urinary catheter days were 31 833 days,incidence of CAUTI was 5.21 per 1 000 urinary catheter days.There was no significant difference in the incidence of CAUTI among patients of different genders (χ2 =1 .23, P =0.54);incidence of CAUTI in patients > 60 years old was higher than those ≤60 years (4.72% vs 2.07%,χ2=30.38,P <0.01);incidence of CAUTI in patients with different duration of catheterization was significantly dif-ferent(χ2 = 251 .14,P <0.01 );with the prolongation of duration of catheterization,incidence of CAUTI also in-creased(trendχ2 =211 .82,P <0.001 ).Patients in department of neurology had the longest average catheterization time(14.84 days)and highest incidence of CAUTI(15.00%,10.11 ‰);patients in the other departments of surgery had the shortest average catheterization time(3.56 days)and lowest incidence of CAUTI(0.97%,2.74‰);inci-dences of CAUTI in patients with urinary catheterization in different departments were significantly different(χ2 =302.24,P <0.001).166 CAUTI patients were isolated 66 isolates of pathogenic strains,86.36% were gram-nega-tive bacilli,33.33% of which were Escherichia coli .Conclusion CAUTI is related to the age of patients and dura-tion of indwelling urinary catheter.Daily assessment on the necessity of indwelling catheter and timely removal of catheter is helpful for reducing the occurrence of CAUTI.

Objective To investigate the eye-movement features of smooth pursuit in subjects at clinical high risk for psychosis.Methods sixty subjects at clinical high risk for psychosis and sixty healthy controls were recruited.The smooth pursuit tasks were assessed in both horizontal (0.4 Hz) and Lissajous (0.2 or 0.4 Hz) condition.The Wechsler Memory Scale-third edition and spatial span subtest were used to assess working memory.The difference of the smooth pursuit performance between the two groups and the relationship between smooth pursuit and working memory were analyzed.Results Subjects at clinical high risk for psychosis showed significantly lower Horizontal components for pursuit gain [Lissajous 0.2 Hz task (0.82±0.12) vs.(0.89±0.09),Lissajous 0.4 Hz task (0.78±0.13) vs.(0.84±0.14)],lower vertical components for pursuit gain [Lissajous 0.2 Hz task (0.80±0.14) vs.(0.86±0.12),Lissajous 0.4 Hz task (0.71±0.15)vs.(0.77±0.16)] and higher mean positional error [Lissajous 0.2 Hz task (37.00±19.10) vs.(30.45± 16.18),Lissajous 0.4 Hz task (44.18±19.70) vs.(37.61±16.26)] compared to healthy controls (P＜0.05).There was a significant correlation between pursuit gain and performance on Spatial Span (Horizontal components:r=0.361,P=0.005;vertical components:r=0.327,P=0.01 1) in the Subjects at clinical high risk for psychosis.Conclusions Subjects at clinical high risk for psychosis showed deficits in smooth pursuit,and the deficits were related to the working memory.

Objective To observed the expression of serum TNF-α and IL-10 in rats with severe acute pancreatitis (SAP) at different altitudes,and to explore the relationships between TNF-α and IL-10,the pathological changes of the pancreas,and the experimental basis for clinical diagnosis and treatment of SAP.Methods 72 specific pathogen free (SPF) Wistar male rats were divided randomly into three groups:1 500 meters altitude (group L),3 300 meters altitude (group M),and 4 300 meters altitude (group H).These three groups were then each divided randomly into four subgroups:control (group n),6 hours after pancreatitis (group p 6 h),12 hours after pancreatitis (group p 12 h),and 24 hours after pancreatitis (group p 24 h).Pancreatitis was induced by intraductal administration of 5％ sodium taurocholate hydrate (NaTc).The rats were killed at 6,12,and 24 hours after NaTc injection in groups p.The group n rats were killed after 6 hours of pancreas observation.Blood samples and pancreatic tissues were collected post mortem and enzyme-linked immunosorbent assay (ELISA) measured serum TNF-α and IL-10.Results Compared with the control (group n),histopathological scores,IL-10,and TNF-α in the same altitude had a significant difference (P ＜ 0.05) in group p at each time point.In the same altitude of group p,histopathological scores and IL-10 were increased with time elapsed (P ＜ 0.05),while TNF-α was decreased with time elapsed (P ＜ 0.05).There was a significant difference between group Mp and Lp in histopathological scores,IL-10,and TNF-α (P ＜ 0.05),and the same result between group Hp and Lp (P ＜ 0.05),but there was no significant difference between group Hp and Mp (P ＜ 0.05).Meanwhile,IL-10 had a positive relationship with histopathological score,but TNF-α had a negative relationship with histopathological score.Conclusions The level of TNF-α increased with increasing altitude but significantly reduced with elapsed time.The level of IL-10 increased with both increasing altitude elapsed time.These results suggested that TNF-o and IL-10 might play a important role at different times in severe acute pancreatitis.

Objective To investigate the effect of oleanolic acid pretreatment on hepatic ischemiareperfusion (I/R) injury in rats. Methods One hundred and twenty-eight male SD rats weighing 230-250 g were randomly divided into 4 groups (n = 32 each): sham operation group (group S), I/R group, 0.5% sodium carboxymethyl cellulose group (group CMC) and oleanolic acid preconditioning (group OA). Partial liver ischemia was produced by clamping hepatic portal vein and hepatic arteries for 60 min with atraumatic mini-clamp, followed by 12 h of reperfusion in group I/R, CMC and OA. Oleanolic acid suspension 100 mg/kg was infused intragastrically in group OA, while the equal volume of 0.5% CMC-Na (in group CMC) and drinking water (in group S and I/R) was infused intragastrically instead once a day for 7 days, and then hepatic I/R was performed at day 8. The left liver was removed and blood sample was taken from inferior vena cava at 0, 3, 6 and 12 h ofreperfusion for determination of serum alanine amino transferase (ALT) activity, superoxide dismutase (SOD)activity, malondialdehyde (MDA) and glutathione (GSH) content, and expression of phospho-phosphatidylinositol3-kinase (p-PI3K), Akt, p-Akt, Bcl-2, Bax, p-Bad and Bad in the liver, and microscopic examination. Results Serum ALT activity and MDA content in the liver were significantly increased, SOD activity and GSH content in the liver were significantly decreased, expression of p-PI3K, p-Akt, Bax, Bad and p-Bad was up-regulated, and Bcl-2 expression was down-regulated during reperfusion in group I/R, CMC and OA as compared with group S (P ＜0.05). Compared with group I/R, serum ALT activity and MDA content in the liver were significantly decreased, SOD activity and GSH content in the liver were significantly increased, expression of p-PI3K, p-Akt,Bcl-2 and p-Bad was up-regulated, and expression of Bad and Bax was down-regulated during reperfusion in group OA (P ＜ 0.05), but no significant change was found in the indexes mentioned above in group CMC (P ＞ 0.05).Serum ALT activity and MDA content in the liver were significantly lower, SOD activity and GSH content in the liver were significantly higher, expression of p-PI3K, p-Akt, Bcl-2 and p-Bad was significantly higher, and expression of Bad and Bax was significantly lower during reperfusion in group OA than in group CMC (P ＜ 0.05).The pathological changes in the liver were milder in group OA than in group I/R. Conclusion Oleanolic acid pretreatment can alleviate hepatic I/R injury by activating PI3K/Akt signaling pathway and inhibiting apoptosis.
