Objective To investigate the clinical effects of mental practice (MP) combined with transcranial direct current stimulation (tDCS) on functional recovery of hemiplegic upper limbs in patients with stroke.Methods The study was conducted by using case-control method.Eighty hemiplegia patients with stroke hospitalized in the Department of Rehabilitation Medicine of Fuyang People's Hospital from August 2015 to December 2016 were recruited for the study.The patients were randomly divided into 2 groups:the observation group (n =41) and the control group (n =39).The patients of the 2 groups were all treated with tDCS,but the patients in the observation group were implemented with MP,once a day,5 days a week and for a succession of 4 weeks.Therapeutic efficacy was evaluated both before treatment and 4 weeks after treatment,by using Fugl-Meyer assessment (FMA) and the modified Barthel index (MBI).Results Before treatment,there were no significant differences in FMA scores and MBI scores,when comparisons were made between the 2 groups.Following treatment for 4 weeks,the FMA and MBI scores of the 2 groups were all significantly improved.However,statistical significance could be seen in the FMA scores of the observation group,as compared with the control group (P <0.05).Conclusion Mental practice combined with tDCS could produce good effects on the motor function of the upper limbs in hemiplegic patients with stroke.

Objective To examine the influence of LEV adjunctive treatment on cognitive function and life quality in RE school-age children. Methods Fifty-five cases of RE children were selected from our hospital from June 2013 to December 2015. Based on original treatment all children were added with LEV treatment for 16 weeks. The initial dose was 8~10 mg/(kg·d),and gradually increased to 50 mg/(kg·d). maintenance dose was 30 mg/(kg·d). Adverse drug reac?tions were recorded and clinical efficacies were determined after treatment. Wechsler Intelligence Scale for Children re?vised in China (WISC-CR) and quality of life in children with epilepsy (QOLCE) was used to evaluate children's cogni?tive function and children's life quality, respectvely. Results Average epilepsy attack frequencies after treatment (3.8± 1.3 vs. 6.6±2.3) times/month decreased significantly compared with before treatment (P<0.05). Clinical control ratio, ex?cellent ratio, effective ratio and ineffective ratio after treatment were 9.1%, 36.4%, 43.6%, 36.4%respectively and total effective ratio was 89.1%. The arithmetic score (10.9 ± 2.6 vs. 9.2 ± 2.1) and mapping score (15.1 ± 3.9 vs. 13.8 ± 3.3) in WISC- CR evaluation increased significantly (P<0.05). Life quality score (65.7 ± 5.7 vs. 62.8 ± 4.9) , cognitive function score (60.0 ± 5.7 vs. 57.4 ± 6.2) and social function score (65.0 ± 6.3 vs. 62.5 ± 5.5) after treatment in QOLCE evaluation in?creased significantly (P<0.05). During medication, the incidences of dizziness, fatigue, lethargy, irritability, euphoria and transient aminotransferase elevation were 12.7%, 9.1%, 20.0%, 9.1%, 3.6%and 3.6%respectively. Sixteen week medica?tion retention rate was 96.4%. Conclusion LEV adjunctive treatment can significantly reduce epilepsy attacks and im?prove cognitive function and life quality in RE children, but attention should be paid to LEV's influence on mental behavior.

OBJECTIVETo investigate the roles of Domain I and Domain II of hepatitis C virus (HCV) 5' untranslated region (UTR) in the translation initiation activity of HCV 5'UTR in different host cell lines.
METHODSThe eukaryotic expression plasmid pCMVNCRLuc (pCN1), in which full-length HCV 5'UTR regulates firefly luciferase expression, was modified by deleting Domain I and the downstream single-stranded sequence (43 bp in total) from the UTR (pCNl-d2), Domain I with the downstream single-stranded sequence and Domain II (118 bp in total) from the UTR (pCNl-d3), or the total UTR (pCNl-d5). The modified plasmids were transfected via liposome into different cell lines with pRL-TK plasmid co-transfected as the normalization control. At 36 h after the transfection, the total cellular RNA was harvested for semi-quantitative RT-PCR, and the relative expression activities of luciferase were assayed with a dual luciferase reporter gene assay system. The translation initiation activities of the truncated HCV 5'UTRs in different translation systems were analyzed.
RESULTSDeletion of Domain I and the downstream single-stranded sequence caused no significant changes of the translational activity of HCV 5'UTR in Hela or C6 cells, but decreased the translational activity by 46% in L-02 cells and increased the translational activity by 46% in 293T cells. Deletion of both Domain I and Domain II resulted in decreased translational activity of HCV 5'UTR by 51% in HeLa cells, but increased the translational activity by 40% in L-02 cells, 60% in C6 cells and 135% in 293T cells.
CONCLUSIONSDomain I and Domain II of HCV 5'UTR perform cell type-specific roles in HCV IRES-driven translation initiation.

Objective To develop a quantitative immunohistochemistry assay for duck hepatitis B virus core antigen (DHB-cAg)in duck liver tissue.Methods By comparison with no repair antigen and repair antigen with high pressure,microwave and trypsin,the best solution of antigen retrieval was determined.By optimizing the parameter of image acquisition and de-ducting blank area,mean density of yellow areas was calculated using Image-Pro Plus 6.0 software.Using the assay devel-oped to determine the level of DHBcAg in liver tissue from duck infected by DHBV,anti-DHBV activity of DHBcMAb-TAT PTD conj ugate was examined.Results SABC method with no repair antigen was selected,which was better than other methods.DHBcAg expression in duck liver tissue could be objectively and accurately quantified by setting Image-Pro Plus 6.0 software parameters and calculating mean density of yellow areas.By comparison with the differences between mean densityat baseline of treatment and end of treatment,it was showed that DHBcMAb-TATPTD conjugate treatment dose-de-pendently reduced the levels of DHBcAg in liver tissue,which show that the assay developed could effectively evaluate the anti-DHBV activity of agent.Conclusion The immunohistochemistry assay developed in this study can objectively and accu-rately evaluate the level of DHBcAg in duck liver tissue.

ObjectiveTo evaluate the gastroprotective activity of ascaridole.MethodsThe gastroprotective effect of ascaridole was evaluated on ulcer healing in rats with acetic acid-induced chronic gastric ulcer,pylorus ligation- and Aspirininduced gastric ulcer.Ascaridole was ig administered with the dosages of 10 and 20 mg/kg once daily for 7 d.Results Ascaridole showed the significant anti-ulcer effects.In acetic acid-induced gastric ulcer rats,the ulcer areas after 10 and 20 mg/kg of ascaridole treatment were (65.1 ± 20.0) and (50.6 ± 11.0) mm2,respectively,which were significant lower (P < 0.01) than that of the control group [(116.7 ± 35.8) mm2].For pylorus ligation model,ascaridole showed a gastric ulcer healing effect in a dose-dependent manner.Ascaridole at the dose of 20 mg/kg showed 50% ulcer protection and had a significant (P < 0.05) gastroprotective activity since it decreased the total acidity and pepsin activity.Compared to the control group,the two dosages of ascaridole showed the significant reduction (P < 0.05) in the ulcer index on Aspirin-induced ulcer.ConclusionThis study provides evidence that ascaridole shows potential efficacy on the healing of gastric ulcers induced by acetic acid,Aspirin,and pylorus ligation.
