Direct economic los-ses in ALL group and ANLL group were 13 089.0 ￥ and 21 565.0 ￥ respectively ;extension of length of hospital stay due to HAI were 10.5 and 10.0 days respectively,differences were statistically significant between case group and control group (both P<0.05). The total hospitalization expense,as well as fees for bed,consultation,treat-ment,laboratory examination,nursing,medicine,traditional Chinese medicine,and blood transfusion in ANLL group were all higher than ALL group,but there were no significant difference.Conclusion HAI in patients with AL can increase hospitalization cost and prolong length of hospital stay.

Objective To investigate the prognostic value of decreased vasopressin (VP)modulation in the late-phase of septic shock. Methods A prospective study was conducted. Fifty-five septic shock patients hospitalized in intensive care unit (ICU)of the First Hospital of Hebei Medical University from January 2012 to February 2014 were enrolled. All patients received 3% hypertonic saline solution infusion. Serum concentrations of sodium and VP were measured before and after hypertonic saline solution infusion. Patients with ratio of difference in sodium and VP before and after infusion of 3%hypertonic saline (△VP/△Na)≤0.5 pg/mmol were defined as non-responders,and who>0.5 pg/mmol were defined as responders. The levels of lactic acid,C-reactive protein (CRP),and vasoactive drug〔dopamine(DA)and norepinephrine(NE)〕usage between the two groups were compared. The 28-day mortality,live time in the dead,and ICU day in survivors were analyzed between the two groups. The receiver operating characteristic curve (ROC curve)was drawn to assess prognostic value of VP. Results There were 30 cases (54.5%) in non-responsive group,and 25 (45.5%)in responsive group. There were no significant differences in the age,acute physiology and chronic health evaluationⅡ (APACHEⅡ)score,central venous pressure (CVP),blood pressure, plasma albumin level,sodium level before and after hypertonic saline solution infusion between the two groups. The baseline level of VP in the non-responsive group was markedly lower than that of the responsive group (ng/L:10.66± 1.57 vs. 17.13 ±5.12,t=6.091,P<0.001). After hypertonic saline solution infusion,the VP level was also significantly decreased compared with that in the responsive group(ng/L:11.65±1.74 vs. 22.50±5.31,t=9.758,P<0.001). The non-responders showed higher lactic acid (mmol/L:3.04±0.55 vs. 2.28±0.38,t=-5.881,P<0.001) and CRP (mg/L:117.9±23.0 vs. 94.9±17.0,t=-4.143,P<0.001),and received larger dosage of vasoactive drugs〔DA(μg·kg-1·min-1):14.8±3.9 vs. 8.9±1.6,t=-5.725,P<0.001;NE(μg·kg-1·min-1):0.96±0.42 vs. 0.40± 0.09,t=-5.625,P<0.001〕for maintaining blood pressure compared with those in responders. The non-responsive group showed higher 28-day mortality(66.7%vs. 40.0%,χ2=3.911,P=0.048)and longer ICU day(days:9.9±2.3 vs. 6.7±1.7,t=-4.044,P<0.001),but the live time in the dead showed no difference between non-responsive group and responsive group(days:5.8±1.9 vs. 6.1±2.3,t=0.384,P=0.704). ROC curve showed that the area under ROC curve(AUC)forΔVP/ΔNa predicting the outcome was 0.828,and theΔVP/ΔNa threshold value of 0.5 pg/mmol had the sensitivity of 66.7%and specificity of 64.0%for prediction of the outcome(95%confidence interval:0.722-0.934). Conclusion Osmotic pressure-regulated VP secretion was impaired and decreased in the late-phase of septic shock, and made the sense in prognosis.

Evolutionary psychology holds such an opinion that negative situation may threaten survival, trigger avoidance motive and have poor effects on the human-body function and the psychological quality. Both disgusted and sad situations can induce negative emotions. However, differences between the two situations on attention capture and emotion cognition during the emotion induction are still not well known. Typical disgusted and sad situation images were used in the present study to induce two negative emotions, and 15 young students (7 males and 8 females, aged 27 ± 3) were recruited in the experiments. Electroencephalogram of 32 leads was recorded when the subjects were viewing situation images, and event-related potentials (ERP) of all leads were obtained for future analysis. Paired sample t tests were carried out on two ERP signals separately induced by disgusted and sad situation images to get time quantum with significant statistical differences between the two ERP signals. Root-mean-square deviations of two ERP signals during each time quantum were calculated and the brain topographic map based on root-mean-square deviations was drawn to display differences of two ERP signals in spatial. Results showed that differences of ERP signals induced by disgusted and sad situation images were mainly manifested in T1 (120-450 ms) early and T2 (800-1,000 ms) later. During the period of T1, the occipital lobe reflecting attention capture was activated by both disgusted and sad situation images, but the prefrontal cortex reflecting emotion sense was activated only by disgusted situation images. During the period of T2, the prefrontal cortex was activated by both disgusted and sad situation images. However, the parietal lobe was activated only by disgusted situation images, which showed stronger emotional perception. The research results would have enlightenment to deepen understanding of negative emotion and to exploredeep cognitive neuroscience mechanisms of negative emotion induction.

Objective To analyse the quality of life in patients with severe acute respiratory syndrome (SARS) for 10 years. Methods Twenty-five SARS patients were collected as SARS group and 25 healthy persons were used as control group. There were no significant differences in general clinical data between two groups. The quality of life of the respondents was evaluated by the MOS item short form health survey (SF-36) including physiological function, physical pain, general health condition, energy, social function, emotional function and mental health. The pulmonary function indicators including forced vital capacity (FVC), one second forced expiratory volume (FEV1), one second rate (FEV1/FVC), total lung capacity (TLC), residual volume (RV), corrected breath diffusing capacity (TLCOc SB) and corrected dispersion rate TLCOc/VA were also compared between two groups. The correlation between each dimension score of pulmonary function indexes and quality of life were analyzed in SARS group. Data of hip and femoral head necrosis were detected by MRI scan in SARS group of patients. Results Total quality of life score was poor in 23 cases (92.0%), and moderate quality of life score in 2 cases (8.0%). The quality of life score was lower in SARS group than that of control group (P<0.01). Data of TLCOc SB was lower in SARS group than that of control group. The score of physiological function was positively correlated with FEV1 and FEV1/FVC. The score of physical pain was positively correlated with FEV1/FVC (P<0.05). There were no significant differences between quality of life score and pulmonary function indicators. There were 11 cases (44%) of avascular necrosis of femoral head, and 14 cases (56%) of non-avascular necrosis of femoral head in SARS group. The score of physiological function was lower in femoral head necrosis group than that of non necrosis group (P<0.05). ConclusionThe lower quality of life in patients with SARS is not only related with psychological factors but also related with physical factors. The damage of pulmonary function and (or) necrosis of femoral head affect the quality of life in patients with SARS, especially the physiological function.
