Objective To investigate the sleep problems and related affecting factors of primary or possibly symptomatic school-aged children with epilepsy.Methods 54 epilepsy children(7 to 12 years old) and the general 54 healthy children whose gender and age were strictly matched with epilepsy group were investigated by using the chinese version of CSHQ.Results ① The total CSHQ score and 6 subscale scores (bedtime resistance, sleep onset delay,sleep anxiety, night wakings, parasomnias, and daytime sleepiness)were significantly higher in the epilepsy group(P<0.05).② In the epilepsy group, different age groups had statistical difference in the total CSHQ score and 4 subscale scores(sleep resistance, sleep onset delay, sleep duration and sleep anxiety) (P<0.05).The seizure controlled group and the uncontrolled group had statistical difference in the total CSHQ score and all subscale scores, except sleep onset delay(P<0.05).There were statistically significant differences in the total CSHQ score and all subscale scores, except sleep-disordered breathing in different seizure frequency groups(P<0.05).Different seizure type groups had statistical difference in the total CSHQ score and 4 subscale scores(sleep resistance, sleep duration, sleep anxiety and daytime sleepiness)(P<0.05).Different seizure time groups had statistical difference in the total CSHQ score and 5 subscale scores(sleep resistance, sleep onset delay, sleep duration, sleep anxiety and night waking)(P<0.05).Monotherapy group and polytherapy group had statistical difference in the total CSHQ score and 4 subscale scores(sleep onset delay, night waking, parasomnias and daytime sleepiness) (P<0.05).③ Multiple linear regression analysis showed that the main influencing factors of the total CSHQ score and some subscale scores were gender, age, control of seizure, frequency of seizure, type of seizure, time of seizure and the number of drug taking.Conclusion Children with epilepsy compared with healthy children are more likely to have sleep problems, and the occurrence of sleep problems may be related to many factors.

Objective To study the effect of Bortezomib on proliferation, apoptosis, cell cycles and activation of NF-?B of non-small cell lung cancer cells (NSCLC) in vitro. Methods The inhibitory action of Bortezomib on cellular growth was determined by MTT. The effects of Bortezomib on cell cycle and apoptosis were assessed by flow cytometry. The influence of Bortezomib on the expressions of NF-?B, I?B and Bcl-2 were detected with Western blotting. Results The inhibitory effects of Bortezomib on the proliferation of NSCLC cells showed a time-and concentration-dependent manner. The growth of NSCLC cells was arrested at G2/M stage after treatment with Bortesomib at 25nmol/L for 48h. Basal expression of NF-?B was found to exist in all the 6 cell lines, with NF-?B expression in nucleus showing an inverse correlation with I?B expression in cytoplasm. Bortezomib threw no significant influence on the basal expression of NF-?B, but significantly blocked the TNF-?-induced nuclear translocation of NF-?B and down-regulated the expression of anti-apoptosis protein Bcl-2 in a time-and concentration-dependent manner. Conclusion With NF-?B-dependent pathway, Bortezomib may inhibit the proliferation of NSCLC cells and induce apoptosis.

Objective:To evaluate iron metabolism disorders in sepsis patients and explore the effect of iron deficiency on mortality.Methods:Patients ( n=130) who were admitted to the emergency intensive care unit (ICU) of the First Affiliated Hospital of Dalian Medical University from September 2016 to July 2018 and met the diagnostic criteria of Sepsis 3.0 were selected, and sex- and age-matched healthy volunteers ( n=20) were enrolled as a control group. Peripheral venous blood samples were collected in sepsis patients on day 1, 3 and 7 after admission, or in the healthy volunteers upon enrollment, to detect iron metabolism-related indicators and interleukin-6 (IL-6); the Sequential Organ Failure Assessment (SOFA) score was calculated upon hospital admission. Iron metabolism-related indicators were compared between the groups; the correlation of plasma iron with hemoglobin, hepcidin, ferritin, IL-6, sTFR/log ferritin and the ability of plasma iron to predict 28-day death of sepsis patients were analyzed. Results:Sepsis patients developed significant anemia on day 3 after admission; plasma iron, transferrin, iron saturation, total iron binding capacity and unsaturated iron binding capacity in the first week of admission were significantly lower than those in the control group; distribution width of red blood cells, ferritin, IL-6, hepcidin and soluble transferrin receptor were significantly higher than those in the control group. Distribution width of red blood cells, ferritin and hepcidin on day 3 and 7 after admission, and plasma iron and iron saturation on day 7 after admission were significantly higher than those on day 1. However, total iron binding capacity and unsaturated iron binding power on day 7, and sTFR/log ferritin on day 3 were significantly lower than those on day 1. Patients in the survival and non-survivor groups in the first week of admission had significant anemia on day 3 and 7, but the anemia was worse in the non-survivor group. Transferrin, total iron binding capacity, and unsaturated iron binding capacity in the non-survivor group in the first week of admission, and plasma iron in the non-survivor group on day 3 and 7, were significantly lower than those in the survival group. Ferritin, IL-6 and hepcidin in the non-survivor group in the first week of admission, and iron saturation on day 7 were significantly higher than those in the survival group. Spearman correlation analysis showed that plasma iron was negatively correlated with IL-6 ( r=-0.391, P<0.01), ferritin ( r=-0.293, P=0.001) and hepcidin ( r=-0.209, P=0.017), but not with hemoglobin ( r=0.005, P=0.958). The area under the operation curve (AUC) for plasma iron for predicting 28-day mortality in sepsis patients was 0.524 (95% CI: 0.416-0.631, P=0.656). Conclusions:Sepsis patients have significant anemia and iron metabolism disorders in the early stage, while non-survival patients are more severe. Reduced plasma iron level has no capacity to predict 28-day mortality of sepsis patients. In addition, decreased plasma iron level is not related to decreased hemoglobin, and thus iron supplementation should be cautious in sepsis patients.
