In order to study the treatment of the children with attention deficit hyperactivity disorder (ADHD), the integrated visual and auditory continuous performance test (IVA-CPT) was clinically applied to evaluate the effectiveness of electroencephalogram (EEG) biofeedback training. Of all the 60 children with ADHD aged more than 6 years, the effective rate of EEG biofeedback training was 91.6% after 40 sessions of EEG biofeedback training. Before and after treatment by EEG biofeedback training, the overall indexes of IVA were significantly improved among predominately inattentive, hyperactive, and combined subtype of children with ADHD (P<0.001). It was suggested that EEG biofeedback training was an effective and vital treatment on children with ADHD.

Objective To investigate the proliferation and apoptosis in stage-ⅠNSCLC and their prognostic implications.Methods Immunohistochemical technology and TUNEL assay was applied to detect proliferation and apoptosis in 118 lung cancer tissues and 30 normal lung tissues as controls.Results Proliferation Index(PI)was up-regulated in lung cancer tissues compared with that in normal lung tissues and was closely related to T-staging,differentiation and smoking.Apoptotic Index(AI)was up-regulated in lung cancer tissues compared with that in normal lung tissues and was closely related to T-staging.PI was not related to AI in stage-ⅠNSCLC.The patients with high PI had a shorter 5-year survival than those with low PI(33.57% and 73.12%,P=0.0001),and the patients with low AI had a shorter 5-year survival than those with high AI(41.48% and 68.80%,P=0.008).Multivariate analysis showed that PI was a significantly independently predictive factor for patients with stage-ⅠNSCLC(RR=2.473,95%CI:1.278~4.784,P=0.007).Conclusion Stage-ⅠNSCLC is a subgroup with high proliferation and apoptosis.Proliferation plays a more important role in stage-ⅠNSCLC.The assessment of proliferation and apoptosis may provide new insight into prognosis and adjuvant treatment for stage-Ⅰ NSCLC.

Objective To investigate the changes of PPARr mRNA and protein expressions in rats with ANP. Methods 36 rats were randomly divided into sham group and ANP group. The rats were sacrificed 3 h, 6 h,12 h after ANP induction, the levels of serum amylase were measured, the pancreatic pathological changes were determined and the expressions of pancreatic PPARr mRNA and protein was examined by RT- PCR and immunohistochemistry. Results In ANP group, the level of serum amylase at 6h was (7170.83± 1635.59) U/L, the scores of pathological changes were 6.67±1.03 and 13.00±2.36, which were much higher than those of sham group (P<0.01) ; the PPARr mRNA expression was 0.18±0.05, and there were no obvious differences compared with that of sham group (0.22±0.03 ) ; PPARr protein expression was 4.17 ±0.98, which was significantly higher than that of sham group (1.83±0.71, P<0.05). Conclusions Inflammatory injury resulted in increased deactivation of pancreatic acinar PPARr, meanwhile PPARr gene expression was inhibited by feedback.

ObjectiveTo investigate the effects of grape seed proanthocyanidin extracts (GSPE) on advanced glycation end product receptor (RAGE),NF-Κb and connective tissue growth factor (CTGF) in the myoeardium of diabetic rats.MethodsTotal 30 streptozotocin (STZ) induced diabetic rats were randomly divided into 2 groups:diabetic group (DM1,n-15) and GSPE (250 mg/ kg,i.g) treated diabetic group (DM2,n= 15).Another two control groups:normal rats(C1,n= 10)and normal rats treated with GSPE (250 mg/kg,i.g) (C2 group,n= 10) were also observed.After 24 weeks,blood was collected to measure fasting plasma glucose (FBG) and RAGE.The protein expression of NF-Κb was determined in myocardial tissue by immunohistochemical staining and Western blot.The protein expressions of RAGE and CTGF were measured by Western blot.Results The levels of FBG and RAGE were significantly higher in diabetic rats than in control rats (P＜0.05).After GSPE treatment,RAGE level significantly reduced (P＜0.05),but FBG had no change in diabetic rats.The protein expressions of RAGE,NF-Κb and CTGF in the myocardial tissue of diabetic rats had marked increase compared with control rats (P＜ 0.05),however,their levels significantly reduced after GSPE treatment (P＜0.05).ConclusionsGSPE may protect diabetic rats against cardiomyopathy,possibly by decreasing the protein expressions of RAGE,NF-Κb and CTGF.

Objective To investigate the effects of Xiao Yao San on intracellular Ca2 + concentration in cultured rat hippocampal neurons in the state of chronic stress and study the mechanism of chronic stress injuring and XiaoYao San protecting. Methods MK-801 acts as tool,cultured rat hippocampal neurons were divided into seven groups, those were group 1 (control), group 2 (normal serum), group 3 (normal serum + Glu), group 4 (model serum + Glu), group 5 (model serum + Glu + MK-801), group 6 (Xiaoyaosan + Glu), group 7 (Xiaoyaosan + Glu + MK-801). to detect intracellular Ca2+ concentration in cultured hippocampal neurons in the simulated micro - environment of chronic stress and after intervention with the serum treated with Xiao Yao San by confocal laser microscope at the same period of time. Results Compared with group 1 (779.97 ± 36.81), concentration of Ca2+ intracellular of group 2 (1092.38 ± 36.41), group 3 (1472.49 ± 76. 19), group 4 (1509.52 ±104.69) and group 5 (1186.97 ±41.92) all increased significantly (P＜0.01) ,group 6 (908.74 ±40.24) increased too (P ＜ 0.05), compared with group 2, concentration of Ca2 + intracellular of group 3,4 and 5 all increased significantly (P ＜ 0.01), but group 7 (721.99 ± 60.33) decreased significantly (P ＜ 0.01). Compared with group 4, concentration of Ca2+ intracellular of group 6 and 7 decreased significantly (P＜ 0.01), group 5 decreased too (P ＜ 0.05), compared with group 6, concentration of Ca2 + intracellular of group 5 increased significantly (P ＜ 0.01),when group 7 decreased significantly (P＜0.01). Conclusion Serum of chronic stress treated with Xiao Yao San has the effect of inhibiting Ca2+ overload in hippocampal neurons,it may work through a variety of signaling pathways including Glu-NR-Ca2+ to maintain the steady-state of Ca2+ concentration in hippocampal neurons, and then to protect neurons from the neurotoxic effects of excitatory.

ObjectiveTo determine the effect of multi-criteria decision analysis (MCDA) on the effect of bundle treatment for severe pneumonia.Methods A prospective historical control observation was conducted. Seventy-five patients with severe pneumonia having received MCDA (from January 2013 to August 2014) were assigned as intervention group. MCDA group was set up by the medical staff. Bundled treatment plan was composed of the MCDA evaluation results, anti-infection, phlegm and other conventional treatment measures which was adjust on time until the patient was transferred out of the respiratory intensive care unit (RICU) or died. Seventy patients with severe pneumonia before receiving MCDA (from August 2010 to December 2012) were set as historical control group. Comparison of general condition before treatment and the incidence of hospital infection, average hospitalization cost, duration of RICU stay and mortality between these two groups were performed.Results There were no statistically significant differences in gender, age, past history, and acute physiology and chronic health evaluationⅡ (APACHEⅡ) score at admission between two groups. Compared with control group, the incidence of hospital infection [1.33% (1/75) vs. 11.43% (8/70),χ2 = 4.723,P = 0.030], mean hospitalization cost in RICU (10 thousand Yuan: 3.44±0.79 vs. 3.76±0.91,t = 2.265, P = 0.025), length of RICU stay (days: 15.01±4.22 vs. 16.92±4.79,t = 2.552,P = 0.012) and mortality in RICU [8.0% (6/75) vs. 21.4% (15/70),χ2 = 5.272,P = 0.032] in intervention group was significantly decreased. Conclusions Application of MCDA in the bundle treatment of severe pneumonia could elevate the scientificalness of decision, and reduce the medical cost. Additionally, MCDA is worth to be generalized because the implementation of guidelines can improve the clinical outcome and prognosis of the patients.
