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 study the pharmacokinetics of triptolide in Tripterygium glycosides tablet in normal rats and adju-vant arthritis model rats in vivo,and provide reference for clinical rational drug use. METHODS:12 SD rats were randomly divid-ed into normal group and model group,6 in each group. Model group was subcutaneously injected complete Freund's adjuvant 0.1 mL to induce adjuvant arthritis model,normal group was subcutaneously injected the same volume of saline. After 14 d model-ing,2 groups were given Tripterygium glycosides tablet suspension 96 mg/kg intragastrically,the blood sample of eyes 0.4 mL were respectively taken before and 10,30,45,60,90,120,150,180,240,300,420 min after administration. The plasma con-centration of triptolide was determined by HPLC,the pharmacokinetic parameters were calculated by DAS 2.0 software,and the parameters were compared. RESULTS:The pharmacokinetic parameters of triptolide in normal group were cmax of(1.139±0.114)μg/mL,tmax of(2.167±0.606)h,t1/2α of(5.500±3.610)h,AUC0-7 h of(5.052±0.371)μg·h/mL,MRT0-7 h of(3.224±0.119)h, and CL of(11.616±2.986)mL/h;and those in model group were cmax of(0.916±0.103)μg/mL,tmax of(3.083±0.801)h,t1/2αof(5.593±1.795)h,AUC0-7 h of(4.707±0.347)μg·h/mL,MRT0-7 h of(3.429±0.139)h,and CL of(11.246±2.638) mL/h. Compared with normal group,cmax in model group was significantly decreased,tmax and MRT0-7 h were significantly prolonged(P<0.05). CONCLUSIONS:Adjuvant arthritis can affect the pharmacokinetics of triptolide in rats in vivo,and promote its absorption and removal.

Objective To screen B and T cell antigen epitopes on Acinetobacter baumannii outer membrane protein 33×103-36×103 (OMP33-36).Methods B and T cell epitopes on OMP33-36 of Acinetobacter baumannii were predicted by bioinformatics methods and synthesized.Recombinant expression plasmid pET-30a-OMP33-36 was cloned and used to express OMP33-36 in a prokaryotic expression system.The expressed OMP33-36 was used to immunize BALB/c mice after purification.Serum sample was collected from each mouse in immunization and negative control groups, and then analyzed by indirect ELISA with synthesized peptides to identify B cell epitopes.Splenocytes were separated from every mouse and then cultured with each of the synthesized peptides, respectively.Double sandwich ELISA was performed to detect IFN-γ secretion in the supernatant of cell cultures for screening of T cell epitopes.Results Candidates of B and T cell epitopes were constructed, which were PB1, PB2, PB3, PT1, PT2 and PT3.Results of the indirect ELISA showed that peptides PB1 and PB2 reacted with the serum samples collected from immunized mice and A450 values of the immunization group were significant higher than those of the negative control group.Compared with the negative control group, enhanced secretion of IFN-γ following peptide PT3 stimulation was observed in the immunization group as indicated by the double sandwich ELISA.Conclusion Two B cell epitopes PB1 and PB2, and one T cell epitope PT3 on the OMP33-36 of Acinetobacter baumannii were successfully constructed and screened out.

Objective To explore the effect of early rehabilitation on patients with hand-foot-mouth disease following acute flaccid paralysis. Methods 31 patients with hand-foot-mouth disease following acute flaccid paralysis were in isolation ward of Children's Hospital of Shanxi Province from Aug. 2009 to Oct. 2010. 21 cases of them were given early rehabilitation while 10 cases were divided into control group because their parents refused the rehabilitation intervention. The course was 4 months. Results In the rehabilitation group, 20 cases recovered,1 improved obviously. In the control group, only 1 improved, 9 had no effect. Conclusion Early rehabilitation can improve the motor function of children with hand-foot-mouth disease following acute flaccid paralysis.

Objective:To investigate the relationship between the expression of serum exsomal miRNA-155-5p (miR-155-5p) and prognosis in patients with esophageal squamous cell carcinoma (ESCC).Methods:A total of 336 samples from ESCC patients in Fujian Provincial Cancer Hospital from October 2014 to December 2015 were collected. The relative expression levels of serum exsomal miR-155-5p were detected by using real-time fluorescent quantitative polymerase chain reaction (qRT-PCR). Cut-off value of the expression levels of serum exsomal miR-155-5p was determined by using X-tile software. Based on the optimal cut-off value, patients were divided into miR-155-5p low expression group and miR-155-5p high expression group. The survival curve was drawn by using Kaplan-Meier method and Cox proportional hazards regression model was used to make survival analysis.Results:The cut-off value of serum exsomal miR-155-5p expression level was 2.340. According to the cut-off value, patients were divided into miR-155-5p low expression group (<2.340) of 51 cases and miR-155-5p high expression group (≥2.340) of 285 cases. There were no statistical differences in age ( χ2 = 0.020, P = 0.887), gender ( χ2 = 0.283, P = 0.595), tumor location ( χ2 = 0.063, P = 0.977), differentiation grade ( P = 0.474), clinical staging ( χ2 = 3.996, P = 0.136) and surgery treatment ( χ2 = 0.941, P = 0.332) of patients in both groups. ESCC patients in serum exsomal miR-155-5p high expression had a higher risk of death compared with patients in miR-155-5p low expression group ( HR = 1.763, 95% CI 1.049-2.961, P = 0.032). Conclusion:The high expression level of serum exsomal miR-155-5p is associated with poor prognosis in ESCC patients and it could be used as a prognostic new marker in ESCC patients.

Objective To explore the effects of traditional Chinese medicinal herbs (TCMHs) on the expression of tyrosinase gene, melanogenesis and proliferation of melanocytes and elucidate the mechanism of TCMHs in promoting melanogenesis. Methods Seven TCMHs including Herba Ecliptae, Spica Prunellae, Caulis Spatholob, etc, which were known to be effective in activating tyrosinase in vivo, were selected. Brownish guinea pigs were selected as the experimental model. The mRNA in situ hybridization (ISH), Schmorl-staining and dopa-oxygenase staining were performed to observe the effects of TCMHs on gene expression of tyrosinase, melanogenesis and melanocyte proliferation. Results The mRNA ISH showed that these seven drugs, especially Herba Ecliptae,Spica Prunellae and Tribulus terrestris could significantly increase the number of positive cells and the intensity of hybridization signal in the treated group as compared with that in the control group (P 0.1). Conclusions These results suggested that these 7 TCMHs including Herba Ecliptae can upregulate the gene expression of tyrosinase, enhance the melanogenesis and promote the proliferation of melanocytes.

Objective: To evaluate the predictive value of plasma amino-terminal pro-B-type natriuretic peptide (NT-proBNP) on short term prognosis in patients with acute coronary syndrome (ACS). Methods: Plasma NT-proBNP levels were measured in ACS patients within 24 h after admission with ELISA method. The 600 ACS patients were divided into two groups: event group （n=108）and no-event group （n=492）according to occurrence of cardiovascular events（including cardiac death, cardiac shock and heart failure）, The NT-proBNP levels were compared between two groups. Single factor and multiple factor Logistic regression analyses were used to evaluate if NT-proBNP was an independent predictor for short term prognosis. Results: The plasma NT-proBNP levels of event group were significantly higher than those of no-event group [1361.2 (965.3, 2088.6) pmol/L vs.605.7 (274.5, 1177.8) pmol/L, p<0.01]. Multiple factor Logistic regression analyses demonstrated that plasma NT-proBNP was an independent predictor for short term prognosis (OR=1.000, p<0.01) in ACS patients. Conclusion: Plasma NT-proBNP was an independent predictor for short term prognosis in ACS patients.
