Objective To investigate the effect of comprehensive treatment and prognosis guide in children with febrile seizures caused by upper respiratory infections.Methods 58 cases of children with febrile seizures caused by upper respiratory infections were divided into the two groups using a random number table method,and the control group received routine first aid and treatment,while the observation group took comprehensive treatment and prognosis guide.The clinical efficacy and recurrence were compared.Results The observation group's abatement of fever time,seizures disappear time and average length of stay was (30.15 ±2.78)h,(4.25 ±0.63)d and (6.51 ±0.52) d,which were significantly less than those of the control group [(45.43 ± 3.14) h,(7.11 ± 0.72) d and (10.02 ± 0.67) d] (t =10.21,9.62,10.30,all P ＜ 0.05) ; The observation group's relapse rate was 13.79％ after treatment,significantly lower than 31.03 ％ of the control group (x2 =11.23,P ＜ 0.05).Conclusion The comprehensive treatment combined with prognosis guide has significant effect in the treatment of children with febrile seizures caused by upper respiratory infections,which can significantly improve clinical symptoms,reduce relapse after treatment.So it has a better clinical value.

Objective To construct pSUPER-SVV vector and obtain its expression in HeLa cells,in order to interfere the expression of survivin.Methods Oligonucleotide sequences specific for survivin were designed for RNA interference(RNAi),after annealed they were ligated to pSUPER.basic vector.After sequencing,the vector of pSUPER-SVV was transfected into HeLa cells by LipofectAmine.The expression of survivin was detected by RT-PCR and FCM.Results The RNAi expression vector of survivin was constructed successfully,which depressed the expression of survivin efficiently.Survivin was significantly depressed on the level of mRNA in HeLa cells compared with the control groups(P

ObjectiveTo explore the prevalence and influencing factors of restless legs syndrome (RLS) in elderly maintenance hemodialysis (MHD) patients, to analyze the relationship between RLS and sleep quality, and to observe the efficacy and safety of hemoperfusion in improving RLS and sleep quality in elderly MHD patients with RLS. MethodsA total of 118 cases with maintenance bemodialysis were involved in this study. The RLS was diagnosed according to the criteria of the International Restless Legs Syndrome Study Group (IRLSSG). The subjects' quality of sleep was assessed by the Pittsburgh Sleep Quality Index (PSQI). The elderly MHD patients with RLS received hemoperfusion once a week for 3 months. The clinical and biochemical indexes were collected including age, gender, duration of hemodialysis, pre-dialysis blood concentrations of creatinine, hemoglobin, parathyroid hormone, β2-microglobulin, etc. T test, X2 test and binary logistic regression analysis were performed. ResultsRLS prevalence was found in 26.27% (11 men, 20 women, the ratio was 0. 55 : 1) of 118 elderly MHD patients. The duration of hemodialysis,sex ratio (female/male), the level of serum phosphorus, β2-microglobulin and parathyroid hormone in elderly MHD patients with RLS were significantly higher than those in elderly MHD patients withoutRLS (t=2. 332,X2=15. 343,t=4. 784,13. 124,10. 900;all P<0. 05). And there were no significant differences in age, dry weight, material of dialyzer membrane, and levels of serum creatinine, urea nitrogen, hemoglobin, hematocrit, calcium, ferritin and transferrin saturation between patients with RLS and without RLS(t=0. 341,0. 008, 1. 055,0. 051,0. 899,0. 912,0. 601,0. 192,0. 200,1. 094;all P>0.05). Logistic regression analysis revealed that serum parathyroid hormone and β2-microglobulinwere the important risk factors for RLS in elderly MHD patients. PSQI was higher in RLS group than in non-RLS group[(10. 7±2.7) vs. (4.9±2.5), t=10. 948,P=0. 000] . The manifestations of poor sleep were poor indexes of subjective sleep quality, sleep duration, habitual sleep efficiency and daytime dysfunction in MHD patients with RLS. And the RLS severity was correlated with PSQI (r=0. 839,P<0. 05). After the treatment with hemoperfusion, the level of serum phosphorus, serum parathyroid hormone, serum β2-microglobulin, RLS severity score and PSQI were significantly decreased in RLS patients compared with pre-hemoperfusion. The vital sign of RLS patients were stable during hemoperfusion, and there were no adverse events after the treatment with hemoperfusion. ConclusionsThe prevalence of RLS is high, and poor sleep quality is found in elderly MHD patients with RLS. Serum parathyroid hormone and β2-microglobulin are the important risk factors for RLS in elderly MHD patients. Hemoperfusion can effectively improve the RLS and sleep quality and is well tolerated.

Objective To evaluate the application of multiple locus variable number tandem repeat analysis (MLVA, 15-locus set)for genotyping of Mycobacterium tuberculosis (MTB) strains of Beijing genotype. Methods Total 72 Beijing genotype MTB strains obtained from Beijing Thoracic Hospital were genotyped by MLVA (15-locus set). The results were compared with that generated from "gold standard"IS6110-RFLP. Results After genotyped by MLVA ( 15-locus set), 72 strains were grouped into 59 types,of which 53 were unique types. The Hunter-Gaston index (HGI) of MLVA ( 15-locus set) was 0.990. The loci QUB-11b, Mtub 21 and QUB-26 were polymorphic in selected Beijing genotype strains. Genotyping by IS6110-RFLP generated 69 types, of which 66 were unique types. The HGI of IS6110-RFLP was up to 0.999, and the MLVA (15-locus set) clustered strains could be further subdivided. Conclusion MLVA(15-locus set) showed better discriminatory ability in Beijing genotype MTB strains, though secondary typing of clustered strains by IS6110-RFLP is needed.
