Epilepsy is a common nervous system seizure disease in children,20%-30% of them is intractable epilepsy.The pathogenesis of intractable epilepsy in children is not yet identify.Some research think that this may be associated with resistance of a variety of diffe-rent mechanisms of antiepileptic drug and abnormalities of multidrug resistance gene expression.The most investigation of multidrug transpor-ter is P-glycoprotein,multidrug resistance-associated protein.They are present in cell membrane and belong to adenosine triphosphate-dependent membrane transport protein.Studies have showed that over-expression of multidrug transporter in temporal lobe brain tissue of patients with refractory epilepsy and animal model of chronic epilepsy reduce the concentration of therapeutic drug in cells.They result in resis-tance by releasing the energy and transferring large amounts of anti-epileptic drugs to exterior of brain capillary endothelial cells in way of active transport.The relationship between multidrug transporter′s structure,distribution,functions and drug-resistant epilepsy are reviewed.

[Objective] To compare the effects of Radix Astragali (RA) and triperygium glucosides (TG) on glomerular mesangial cells (GMC) proliferation and interleukin-6 (IL-6) secretion. [Methods] GMC were cultured with in-vitro cell culture technology. Serum containing RA and serum containing TG were prepared with serum pharmacological methods. GMC proliferation was detected by methylthiazolyltetrazolium (MTT) assay and IL-6 level by enzyme-linked immunosorbent assay (ELISA) to evaluate the effect of low-, moderate- and high-dosages of RA-containing serum and TG-containing serum under the condition of GMC over-proliferation. [ Results] Different dosages of RA-containing serum and TG-containing serum inhibited GMC proliferation and IL-6 secretion in a dose-effect manner, and the inhibitory effect of high- and moderate-dosage TG and high-dosage RA was stronger. [Conclusion] Under the condition of in-vitro GMC over-proliferation, RA has the similar inhibitory effects on GMC proliferation and IL-6 secretion with TG. The combined treatment of RA and TG can reduce the dose of TG and probably has an action in increasing effect and reducing toxicity.

Objective To observe the clinical efficacy of electroacupuncture plus nasal irrigation in treating upper airway cough syndrome (UACS).Method A total of 114 UACS patients were randomized into 3 groups, 38 cases in each group. Group A was treated with acupuncture plus electrical stimulation with sparse-dense wave, group B was intervened by nasal irrigation with Shuang Huang Lian, and group C was treated with the two methods together. The clinical efficacies of the three groups were compared.Result The total effective rates were respectively 84.2%, 73.7% and 94.7% in group A, group B and group C. The total effective rate of group C was significantly different from that of group A and group B (P<0.05).Conclusion Electroacupuncture plus nasal irrigation can produce a more significant therapeutic efficacy compared to electroacupuncture or nasal irrigation alone.

Objective To investigate the error monitoring function damages on the patients with schizo?phrenia ( SCH) . Methods A total of 32 patients with schizophrenia were compared with matched 34 health con?trols ( HC) on the error monitoring tasks which were compiled by E?Prime. Results The comparison between SCH group ((713.22±174.52)ms,( 491.14±170.29) ms,( 1060.31±130.84) ms,(8.28±12.55)time,( 8.00± 7.53)time respectively) and HC group ((560.73±156.94) ms,(395.62±188.03) ms,(989.85±104.33) ms, (2.97±4.13) times,(3.12±6.50) times) on the reaction time of choice,assessment,incongruent condition,the numbers of uncertain and the numbers of dropout were significant ( t=-3.737, P=0.000;t=-2.159, P=0.035;t=-2.426, P=0.018;t=-2.282, P=0.022;t=-2.824, P=0.006) . The SCH group and HC group did not signifi?cantly difference in Full Correct((124.72±23.74)/(131.74±21.96)times),Full Error((15.69±17.64)/(13.35± 18.63)times),Part Correct((6.83±10.40)/(4.21±7.03)times),Part Error((2.91±10.91)/(0.62±1.10)times) and Accuracy((0.831±0.161)/(0.874±0.159))(P>0.05).There was no significantly correlation among the course of disease,HAMA,HAMD and the error monitoring. Conclusion These results demonstrate that the error monitoring function damages on the patient with SCH may be involved in the dysfunction of anterior cingulate cortex.

Background:The incidence of inflammatory bowel disease( IBD ) is increasing in recent years,however,its pathogenic mechanism has not been fully clarified. Previous studies revealed that adipokines played crucial roles in regulating intestinal inflammation. Aims:To investigate the role of visfatin,an adipocytokine,and its clinical significance in active IBD. Methods:Ninety-one patients with active IBD including 61 Crohn’s disease( CD)and 30 ulcerative colitis ( UC)at the First Affiliated Hospital of Soochow University and Suzhou Municipal Hospital from May 2015 to Dec. 2015 were enrolled in this study,and 48 healthy subjects were served as controls. Serum level of visfatin was determined by ELISA. Correlation of serum visfatin level with clinical features of IBD was analyzed,its diagnostic performance for IBD was assessed by ROC curve. Results:Serum level of visfatin was significantly higher in patients with active CD and UC than in healthy controls[(385. 24 ± 112. 64)pg/mL and(378. 91 ± 118. 57)pg/mL vs. (321. 11 ± 96. 27)pg/mL, P all ﹤0. 05]. Significant positive correlation was found between serum visfatin level and disease activity index(Mayo score)of UC( r =0. 398,P ﹤0. 05 ),however,no correlations were found between serum visfatin level and disease activity index of CD,CRP and ESR,two common inflammatory indicators for IBD and location of IBD(P all ﹥0. 05). The area under curve( AUC)of serum visfatin for diagnosis of CD and UC were 0. 654 and 0. 622,respectively;the diagnostic accuracy was relatively low. Conclusions:Serum visfatin might be associated with the active intestinal inflammation in IBD and has the potential to be served as a clinical index for active UC.

Objective To investigate thc cvent-based prospective memory (EBPM)and time-based prospective memory(TBPM)in the inpatients with abstinent alcohol dependence and the relationships between prospective memory and symptoms.Methods 32 male patients with alcohol dependence and 30 normal controls matched by age,education,HAMD and HAMA were assessed with a neuropsychological battery of tests including EBPM and TBPM tasks.Results A statistically significant in EBPM was observed between patients with alcohol dependence and normal controls (3.91 ± 0.69 vs.4.47 ± 0.63,t =-3.348,P ＜ 0.0 1) and the same result in TBPM (3.28 ±0.77 vs.4.20 ±0.66,t=-5.032,P＜0.01).The positively correlation was showed between the duration of abstinence and EBPM (r =0.444,P ＜ 0.05),as well as TBPM (r =O.423,P ＜ 0.05) in the patients.Conclusion The results suggest abstinent alcohol dependence patients impairs both EBPM and TBPM.PM shows correlated with duration of abstinence moderately in the patients.

Objectives:To study the pathological behavior and the value of transforming growth factor β1(TGF-β1) in predicting prognosis in pulmonary hypertension associated with congenital heart disease.　Methods:Lung tissues from 29 patients with congenital heart diseases associated with pulmonary hypertension were examined by surgical biopsy of the lung. All samples were examined for the expression and localization of TGF-β1 by immunohistochemical technique with anti-TGF-β1 antibody.　Results:Twenty-six out of 29 showed positive staining of intracellular endotheliocyte TGF-β1(89.65%),16 samples showed extracellular matrix TGF-β1 staining(55.17%).Statistically, there was significant difference between Ⅰ～Ⅱ and Ⅲ～Ⅵ pathological degrees in extracellular matrix(P<0.05).　Conclusions: TGF-β1 plays an important biological role in the formation of pulmonary hypertension after congenital heart disease. It is conductive in predicting prognosis.

OBJECTIVETo discuss the protective effect of Mailuoning injection on ischemia/reperfusion (I/R) injury in rats and its mechanism.

METHODHealthy male adult Sprague-Dawley (SD) rats were randomly divided into the sham operation group, the model group, the edaravone (3 mg x kg(-1)) control group, and Mailuoning high, middle and low-dose groups (4, 2, 1 mL x kg(-1)), with 10 rats in each group, and administered with drugs through tail intravenous injection. The middle cerebral artery occlusion (MCAO) was adopted to establish the rat ischemia/reperfusion model. After the ischemia for 2 h and reperfusion for 24 h, the pathological changes in neurovascular units (NVU) of brain tissues at the ischemia side was observed by HE staining. The expressions of glialfibrillary acidic protein (GFAP) and ionized calcium-binding adaptor molecule 1 (Ibal) were detected by the immunohistochemical method. The expressions of tumor necrosis factor-alpha (TNF-alpha), interleukin 1beta (IL-1beta), vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) were detected by the western blotting technique.

RESULTMailuoning injection could significantly improve the pathological changes in cortical penumbra brain tissue UVN of (I/R) rats, reduce the number of GFAP and Ibal positive cells, and significantly decrease the expressions of TNF-alpha, IL-1beta, VCAM-1 and ICAM-1 of brain tissues of I/R rats.

CONCLUSIONMailuoning injection shows an obvious protective effect on UVN of I/R rats. Its mechanism may involve the inhibition of the activation of astrocyte and microglia and the secretion and expression of various inflammatory factors.
