Objective To explore the characteristic and clinical value of Somatosensory Evoked Potential SEP and event?related potential P300 in patients with Juvenile Myoclonic Epilepsy (JME), trying to provide neuroelectrophysiological evidence for the pathogenesis, diagnosis and antiepileptic drug efficacy of this disease . Methods 28 patients with JME and 30 healthy controls were enrolled in the research. They were applied the SEP and P300 before and after one year treatment. Results (1) The amplitude of SEP in patients with JME was significantly higher than those in the control group(P=0.000), the abnormal rate was 75%(21/28), while the latency of SEP was no significant difference (P>0.05); The latency of P300 in patients with JME was significantly longer (P = 0.000), 2 out of 28 cases were poorly differentiated, 9 cases were longer (11/28, 39%), while the P300 amplitude was no significant difference(P=0.110). (2) After treatment, the amplitude of SEP was significantly lower (P<0.05), the latency of P300 was significantly shorter (P=0.001). (3) The amplitude of SEP had a positively linear relationship with the latency of P300 (r = 0.818, P = 0.000). Conclusions The SEP amplitude was significantly higher in patients with JME, often accompanied by a huge SEP, so SEP can provide electrophysiological evidence for the pathogenesis and diagnosis of this disease.And P300 may give a chance to find the subclinical cognitive abnormalities and to intervent it early. The SEP had a positively linear relationship with the P300, simultaneously dynamic monitoring the change of SEP amplitude and P300 latency may become an objective evaluation for the antiepileptic drug efficacy.

Objective To assess the association of subclinical thyroid dysfunction with fractures. Methods Medline, Embase, Pubmed, Cochrane Library, CBM, CNKI, Wan Fang, and VIP databases were systematically searched from January 1990 to August 2015 to identify prospective cohort studies which have studied the risk of fracture in patients with subclinical thyroid dysfunction. The relative risks ( RR) of cohort studies were pooled respectively, depending on the result of heterogeneity test among the individual studies search. The Stata (version 13. 0) software was used for meta-analysis. Results Nine prospective cohort studies including 292460 participants were identified as eligible for the meta-analysis. RR of subclinical hyperthyroidism for fracture was 1. 39(95%CI 1. 24-1. 55);for hip fracture, RR was 1. 24(95%CI 1. 10-1. 40);for nonspine fracture, RR was 1. 32 (95%CI 1. 09-1. 60). Different gender for subclinical hyperthyroid was associated with higher fracture rates:for females, RR was 1. 15(95%CI 1. 04-1. 27); for males, RR was 1. 31 (95% CI 1. 08-1. 59). The incidence of fracture in patients with subclinical hyperthyroidism was higher during the follow-up. For subclinical hypothyroidism, the RR was 1. 21(95% CI 1. 03-1. 42). Subgroup analysis indicated that there were significant differences between endogenous/exogenous subclinical hyperthyroidism and euthyroid, but no differences between endogenous/exogenous subclinical hypothyroidism and euthyroid were found. Conclusion Subclinical hyperthyroidism is associated with an increased risk of fracture in the population, especially hip fracture and nonspine fracture. During the course of subclinical hyperthyroidism, the incidences of fracture should be noticed both in females and males. However, there is no evidence which could prove a definite association between subclinical hypothyroidism and the risk of fracture.

ObjectiveTo investigate the character outpatients in clinical psychological department of a general hospital.MethodsAll the outpatients visited clinical psychological department were asked to evaluate with SCL-90.ResultsThe scores of all factors of SCL-90 were higher than national norm.Neurosis,affective disorder and schizophrenia were the major psychoses.ConclusionMost of the visitors have psychological problems or mental disorder.

Objective To explore and develop methods for encephalomyocarditis virus (EMCV) identification.Methods According to the genetic sequence VR-129B of EMCV recorded in the GenBank,five gene fragments were selected to design primer sequence pairs.RNA was extracted to run RT-PCR,and then the products of amplification were identified by agarose gel electrophoresis.The results of DNA sequences were compared with the sequences in GenBank of the same EMCV strains.Antiserum was prepared based on the EMCV cultured in RK cells for establishing indirect immunofluorescence assay (IIFA) and neutralization test method,and verification for precision and specificity of the two methods were carried out after it.Antiserum that was prepared with GST-VP1 and GST-VP2 expressed in E.coli was reacted with the purified EMCV in Western blot test.Results By sequencing and comparing,the similarity of DNA fragments between the obtained and the GenBank recorded was reached 98％ to 100％.The antiserum of No.20100901 batch that was chosen as the first antibody at a dilution of 1 ∶ 160 to develop IIFA brought about a better specificity.The neutralization titers of 20100901 batch antiserum was 1 ∶ 30 211 measured by fixing virus and diluting serum method,which showed good specificity and precision.The results of the Western blot test showed two clear bands above and under 33×103 respectively,which matched the theoretical value.Conclusion The RT-PCR,indirect immunofluorescence,neutralization test and Western blot method for EMCV strains identification were established initially.

Objective To probe deficits in visuospatial attention using an attention network test (ANT) in patients with frontoparietal network lesions. Methods The ANT was used to measure the alertness, orienting and executive control abilities of 25 patients with local brain lesions, including 13 with frontal and 12 with parietal damage. Their results were compared with those of health adults. Results During ANT tasks, the patients' responses were significantly slower on each cue and target condition than controls', and showed deficits in their alerting and orienting networks. The efficiency of executive control was impaired in patients with frontal lesions, but increased with parietal lesions. Conclusions These findings suggest that the frontoparietal network is involved in alerting and orienting, but the executive control function may be selectively associated with the frontal lobe. ANT is an efficienttool for studying visual attention and cognition.

Objective To assess the efficacy of intedeukin (IL)-1Ra,a recombinant human IL-1receptor antagonist,plus methotrexate ( MTX ) in patients with active rheumatoid arthritis ( RA ) refractory to MTX therapy.Methods A total of 54 patients with active RA,who had been taking MTX at a stable dosage,were randomized to receive daily subcutaneous injections of IL-1Ra (80 mg) or placebo.The proportion of patients who had a response as assessed by ACR20,ACR50 and ACR70 was analyzed using Chi-square test measures.Baseline variables and DAS28 were analyzed using Student's t-test (parametric) or Wilcoxon's rank sum test (nonparametric) as appropriate.Results After 24 weeks,more patients achieved clinical benefits treated with IL-1Ra plus MTX compared with MTX alone (64％ vs 17％,P=-0.004) as determined by the ACR20 improvement.In the IL-1Ra group,an ACR50 response was observed in 38％ and an ACR70 response in 17％.None of the patients treated with MTX alone achieved ACR50 or ACR 70 improvement.However,9 of 42 (21％) patients in the IL-1Ra group,who showed therapeutic response initially,had secondary drug failure to IL-1Ra therapy thereafter.A significant increase in mean DAS28 from baseline was found in the nonresponders to IL-1Ra,compared with placebo.Conclusion IL-IRa is effective for the treatment of patients with active RA by blocking IL-1.However,the efficacy of IL-1Ra is lost soon in about one-fifth of patients in soite of initial good resoonse.

Objective To investigate the effect of miRNA -1 00 on the proliferation of human leukemia cells HL -60,and to explore the mechanism of this action.Methods The bioinformatics software and database were applied to predict and analyze target genes of miRNA -1 00.The vector contained the target gene 3′UTR portion cloned into a luciferase reporter construct.A luciferase reporter assay was performed following co -transfection of small molecular miRNA -1 00 mimics and target gene wild -type or mutant plasmid into HEK -293T cells.HL -60 cells were trans-fected with miRNA -1 00 mimics or anti -miRNA -1 00.After transfection,Western blot was applied to validate the expression of carboxy -terminal domain small phosphatase -like protein (CTDSPL),and the viability of HL -60 was measured by using cell counting kit (CCK -8)assay at 24 h,48 h,72 h,96 h.Results Online software predicted that CTDSPL was likely to be the target gene of miRNA -1 00.Dual luciferase reporter gene assay system showed that miRNA -1 00 could significantly suppress the activity of reporter gene containing CTDSPL 3′-UTR which decreased by about 57.1 %(P =0.000 7).Western blot showed that the expression of CTDSPL was increased after being trans-fected with miRNA -1 00 antisense oligonucleotides and decreased after being transfected with miRNA -1 00 mimics.At the same time,the growth rate of cells treated with miRNA -1 00 mimics or CTDSPL miRNA -1 00 was increased com-pared with that in control by CCK -8 test (P <0.05 ).Conclusions CTDSPL is a downstream target gene of miRNA -1 00.miRNA -1 00 can promote leukemia cell proliferation by inhibiting the expression of CTDSPL.
