Objective To assess language function in children with benign epilepsy with centrotemporal spikes in children(BECTS) and its association with the age of epilepsy onset.Methods We assessed language function in 63 children with BECTS and 30 age and sex matched controls by the subtest of CWISC.Results Children with BECTS performed significantly worse on all language tasks as compared to controls and overall better language function was positively correlated with older age of the child.Early age at seizure onset demonstrated significant negative correlation with language dysfunction,age below 6 years being related to the lowest performance scores(P ＜ 0.05).There was no relationship between the language function and the laterality of epileptic focus,seizure treatment status,or the duration of epilepsy(P ＞ 0.05).There was significant relationship between the language dysfunction and onset age of epilepsy (P ＜ 0.05).Conclusion Children with BECTS have language difficulties that are more pronounced in younger age group.Despite better language functioning in older children with BECTS,their verbal abilities remain inferior to those of children without epilepsy.Early age at seizure onset is a significant factor predicting worse language functioning in children with BECTS.

Objective To investigate and analyze the perioperative nursing of patients with breast cancer, and explore the effectiveness of the application of mind map in perioperative nursing care of patients with breast cancer. Methods The cluster sampling method was employed, and 265 patients with breast cancer receiving radical mastectomy treatment from department of general surgery of the First Affiliated Hospital of Liaoning Medical University were gathered according to the inclusion and exclusion criteria. 137 cases were assigned to test group (May 2014 to April 2015), and 128 cases were assigned to control group (May 2013 to April 2014 ). Nursing work was improved by establishing research group, discussing the design of perioperative nursing mind map and applying mind maps. Effect was evaluated by evaluating the incidence of postoperative complications in patients with breast cancer, the quality of patient′s life and the patient′s satisfaction. Results The incidence of bleeding, seroma, flap necrosis, upper extremity swelling and other postoperative complications of patients with breast cancer in test group was 26.28%(36/128),and that in control group was 73.44%(94/137). The differences between the two groups were of statistical significance (χ2=58.891, P<0.01). The perioperative survival quality scores of physiology, society/family, emotions, function, additions and total in the test group were (2.43 ± 1.09), (2.64±0.97), (2.85±0.97), (2.43±1.09), (2.22±1.12),(2.34±1.13), and that in the control group were (1.89± 1.09), (1.89 ± 1.06), (1.78 ± 0.92), (1.89 ± 1.09), (1.76 ± 1.05), (2.00 ± 1.09)respectively. The differences between the two groups were statistically significant (t=4.664-10.829,P<0.01). The proportion of patient satisfaction in test group was 94.89%(130/137),and that in control group was 82.03%(105/128), respectively. The differences between the two groups were statistically significant (χ2=10.900, P < 0.01). Conclusions Application of mind map in nursing intervention is able to help nurses to grasp the key content and direction of perioperative nursing on patients with breast cancer. More importantly, not only can it improved patients′quality of life and reduce the incidence of postoperative complications, but also increases patients′satisfaction.

Objective To examine the difference in myocardial protection provided by continuous and intermittent warm blood cardioplegia during coronary artery bypass (CAB) .Methods Thirty ASA Ⅰ-Ⅱ patients undergoing CAB with warm CPB were randomly divided into two groups : (A) continuous warm blood cardioplegia ( n = 15) and (B) intermittent warm blood cardioplegia ( n = 15) . During CPB the body temperature was maintained at 33℃ -34℃ . Arterial blood samples were taken before skin incision (T0) , 1 h after going on CPB (T1 ) and 6h , 24h after coming off CPB (T2, T3 ), for determination of plasma concentration of cardiac troponin T (cTnT) using ELISA method. A small piece of myocardium was obtained from right ventricle (about 1g ) before aortic crass-clamping and after the aortic clamp was removed for determination of myocardial ATP content and ultrastractural examination. Results The demographic data were comparable between the two groups. Plasma cTnT level increased significantly at T1 and T2 as compared with the baseline values (T0) and then returned to normal level at T3 in both groups. The cTnT level was significantly higher in group B than that in group A at T2 (6h after weaning from CPB)The myocardial ATP content decreased significantly after aortic clamp was removed as compared with that before cross-clamping of aorta, but myocardial ATP content in group A was significantly higher than that in group B after release of arotic clamp. Mitochondria score was significantly higher after release of aortic cross-clamp than that before aortic cross-clamping.Conclusion Continuous warm blood cardiaplegia is superior to intermittent warm blood cardioplegia during CPB in terms of myocardial protection.

Objective To determine whether plasma Leptin level is associated with atherosclerosis in maintenance hemodialysis(MHD)patients.Methods During 1997-01~2003-06,plasma Leptin levels in MHD patients and healthy volunteers were measured and intima-media thickness(IMT)and prevalence of atherosclerotic plaques of the extracranial common carotid artery were also measured.Results Plasma Leptin levels in the MHD patients were higher than those in the healthy volunteers(P

Objective To determine the effect of unfractionated heparin (UFH) on lipopolysaccharide (LPS)-induced expression of chemokines and nuclear factor-κB (NF-κB) signaling pathway. Methods Human pulmonary microvascular endothelial cells (HPMECs) were cultured in vitro, and the cells between passages 3 and 5 were used in the experiments. The cells were divided into control group, LPS challenge group, 1 kU/L or 10 kU/L UFH+LPS group, and NF-κB inhibitor N-tosyl-L-lysyl chloromethyl-ketone (TLCK) group (TLCK+LPS group). HPMECs in LPS challenge group were treated with 10 mg/L LPS. UFH pretreatment with different dosages groups were treated with 1 kU/L or 10 kU/L UFH 15 minutes before LPS challenge. Cells in the TLCK+LPS group were treated with 10 μmol/L of TLCK 30 minutes before the addition of LPS, and HPMECs in control group were treated with an equal volume of phosphate-buffered saline (PBS) instead. The cells were harvested 1 hour after LPS challenge, and the nuclear translocation of NF-κB was determined by immunofluorescence assay to detect the effect of UFH on NF-κB activation. The levels of interleukin-8 (IL-8) and monocyte chemoattractant protein-1 (MCP-1) in cell culture supernatants were determined by enzyme linked immunosorbent assay (ELISA) 3 hours and 6 hours after LPS challenge to detect the effect of UFH on LPS induced expression of chemokines and its mechanism of effect on NF-κB signaling pathway in HPMECs. Results ① In the control group, NF-κB was mostly located in the cytosol as shown by immunofluorescence. Treatment of HPMECs with LPS significantly increased the translocation of NF-κB from the cytosol to nucleus. UFH suppressed LPS-induced NF-κB activation both in 1 kU/L and 10 kU/L dosages, and 10 kU/L UFH gave even better results. ② Compared with control group, the levels of IL-8 and MCP-1 in the supernatants in LPS challenge group were significantly increased at 3 hours and 6 hours after LPS challenge [IL-8 (ng/L): 387.1±26.4 vs. 23.8±8.1 at 3 hours, 645.5±69.6 vs. 125.7±18.7 at 6 hours; MCP-1 (ng/L): 3 654.9±467.9 vs. 721.6±61.3 at 3 hours, 8 178.5±792.6 vs. 1 324.7±148.7 at 6 hours, all P < 0.05]. Compared with that of LPS challenge group, in 1 kU/L and 10 kU/L UFH pretreatment groups, the levels of IL-8 and MCP-1 were significantly decreased [IL-8 (ng/L): 315.3±24.8, 275.8±31.1 vs. 387.1±26.4 at 3 hours, 557.8±43.3, 496.9±38.7 vs. 645.5±69.6 at 6 hours; MCP-1 (ng/L): 2 924.1±267.9, 2 668.3±522.6 vs. 3 654.9±467.9 at 3 hours, 7 121.7±557.2, 6 563.9±576.4 vs. 8 178.5±792.6 at 6 hours, all P < 0.05]. The results indicated that 10 kU/L UFH yielded better results. However, inhibition study using the known NF-κB inhibitor TLCK could decrease LPS-induced increase in IL-8 and MCP-1 levels [IL-8 (ng/L): 162.4±21.3 vs. 387.1±26.4 at 3 hours, 274.1±22.6 vs. 645.5±69.6 at 6 hours; MCP-1 (ng/L): 1 478.2±138.5 vs. 3 654.9±467.9 at 3 hours; 3 667.6±259.4 vs. 8 178.5±792.6 at 6 hours, all P < 0.05]. Conclusions The levels of IL-8 and MCP-1 were increased obviously in LPS treated HPMECs. UFH might suppress LPS-activated NF-κB signaling pathway, contributing to the inhibitory effects of chemokines in HPMECs.

The HPLC-UV-Fluorescence technique and HPLC-UV-MS technique were used to determine fluorescence molecule in gastric juice of patients with malignant gastric cancer,which is identified as tryptophan. Lidocaine was detected in gastric juice of patients who were examined by gastric endoscopy. A method was developed to determine concentration of tryptophan and lidocaine in gastric juice using HPLC-UV technique,in which Kromasil C_(18) column(150 mm×4.6 mm,5μm) and methanol(containing 0.1% trifluoroacetic acid (TFA))-water(containing 0. 1% TFA) as gradient mobile phase were used. The linear relationships were obtained between the concentration of tryptophan in the range of 0.5 - 200 mg/L and its peak area at 278 run with correlation coefficient of 0.9994,and between the concentration of lidocaine in the range of 20 -5000 mg/L and its peak area at 254 nm with correlation coefficient of 0.9992. The limit of detection is 0.15 mg/L for tryptophan and 5 mg/L for lidocaine. The recovery is 70. 8% - 110. 4% for tryptophan and 87. 1% -116.2% for lidocaine. 38 gastric juice samples of patients with malignant gastric disease and 48 gastric juice samples of patients with benign gastric disease were tested and the concentration of tryptophan in those two groups of gastric juice samples was apparently different.
