Objective To observe the effect of the body weight support training (BWST) on walking ability of children with cerebral palsy (CP). Methods 50 children with CP were divided into the BWST group （n=30） and control group（n=20）. All cases were treated with physical therapy, but the BWST group were added with BWST. The scores of D and E dimensions of the Gross Motor Function Measure Scale (GMFM) were used to assess the walking ability before and after the treatment, respectively. Results The scores of D and E dimensions of GMFM improved in both groups after treatment (P<0.01), and that of the BWST group improved more than control group （P＜0.05）. Conclusion BWST can facilitate the recovery of the walking ability after cerebral palsy.

Objective To explore the impact of hypoxia/reoxygenation stimulation on phenotype and immune activity of dendritic cells(DCs) cultured from murine bone marrow. Methods Mouse DCs were generated from bone marrow cells and were divided into control group and hypoxia/reoxygenation group. DC in control group was cultured at normal condition, and in hypoxia/reoxygenation group was cultured at hypoxic condition for 4 h followed by cultured at normal condition for 24 h. Flow cytometry and mixed lym-phocyte reaction(MLR) was used to detect the phenotype and functional properties of DCs. ELISA was used to detect the concentration of TNF-α, IFN-γ and IL-12 in the supernalant, Imrounochemistry was used to de-tect the concentration of NF-κB. Results Hypoxia/reoxygen stimulation increased the CD80, CD86, MHC Ⅱ in the cytomembrane of DCs and TNF-α, IFN-γ, IL-12 concentration in the supernalant. Hypoxia/reoxy-gen stimulation also promoted the shift of NF-κB to karyon. Conclusion Under hypoxia/reoxygen stimula-tion, DCs express high level of surface molecules, and possess strong immune activity.

Objectives: To describe prevalence of personality dysfuction and personality disorders (PD) and their distribution in senior high school students in Beijing. Methods: By means of cross-sectional study, 10003 senior high school students were investigated by Personality Disorder Questionnaire-fourth edition (PDQ-4), Parental Rearing Questionnaire (Egma Minnen av Bardndosnauppfor-stran, EMBU), General Information Questionnaire, and International Personality Disorder Examination (IPDE) to diagnose PD according to the criteria of ICD-10 and DSM-IV. Results: In the students of first grade, the mean score of PDQ-4 was (25. 38 ± 9. 64). Male students had higher PDQ-4 scroes than those of female. Students in rural high schools had higher PDQ-4 scroes than those of students in urban high schools. Students in general high schools had the highest PDQ-4 scroes, followed by students in disctrict-level key high schools, and the students from city-level key high schools had the lowest PDQ-4 scroes. The prevalence rate of personality dysfunction was 8. 3％ with similar distributions of PDQ-4 scroes by gender, residential area, and rank of school. In the students of third grade, the mean score of PDQ-4 was (23. 10 ± 10. 20). Male students had higher PDQ-4 scroes than those of female. The prevalence rates of personality dysfunction and PD were 5. 8％ and 1. 83％, respectively. The correlation coefficients of EMBU had statistical significances and four common factors were identified by factor analysis. The heritability of overall PD of father and mother were 0. 71 and 0. 72, respectively. The heritability of each PD cluster was higher than 0. 6. Conclusion: The prevalence rates of personality dysfunction and personality disorder in Beijing, China is lower than those in other countries. The genetic factor plays an important role in the development of PD.

Methods SD rats aged 21-30 d were randomly divided into the control group(48 rats),the epilepsy group(48 rats)and the melatonin group(48 rats),and each group was subdivided into 4 subgroups according to the time points of 24 h,48 h, 72 h,and 7 d,with 12 SD rats in each subgroup. Fluorescence quantitative polymerase chain reaction and immunohisto-chemical technique were used to analyze the expressions of NLRP3,Caspase-1 and interleukin(IL)-1β in hippocam-pus areas of rats at different points of time after seizures were induced,and their behavior changes were observed. Results The number of NLRP3-positive cells in the epileptic group increased,and reached the peak at 72 h. At 24 h,48 h,72 h,7 d,the number of NLRP3-positive cells in the epilepsy group(14. 20 ± 1. 64,23. 60 ± 1. 14,31. 20 ± 1. 30,25. 40 ± 2. 07)was significantly increased compared with those of the melatonin group(10. 60 ± 0. 89,17. 80 ± 1. 48,24. 00 ± 0. 71,20. 20 ± 1. 92)and the control group(2. 60 ± 0. 89,2. 40 ± 1. 14,2. 40 ± 1. 14,2. 40 ± 0. 55),and the differences were significant(F＝122. 977,375. 125,962. 743,262. 916,all P＜0. 05). The NLRP3 mRNA relative expressions in the epilepsy group (2. 57 ± 0. 12,3. 34 ± 0. 10,4. 84 ± 0. 19,3. 55 ± 0. 13)were significantly increased compared with those of the melatonin group (2. 03 ± 0. 08,2. 71 ± 0. 08,4. 03 ± 0. 14,2. 48 ± 0. 18)and the control group(1. 07 ± 0. 13,1. 08 ± 0. 15,1. 08 ± 0. 23,1. 07 ± 0. 18),and the differences were significant (F ＝422. 386, 1 154. 957,1 132. 112,512. 149,all P ＜0. 05);the Caspase -1 mRNA relative expressions in the epilepsy group (2. 47 ± 0. 07,3. 05 ± 0. 15,4. 39 ± 0. 18,3. 14 ± 0. 11)were significantly increased compared with those of melatonin group(1. 85 ± 0. 07,2. 49 ± 0. 08,3. 60 ± 0. 12,2. 15 ± 0. 12)and the control group (0. 98 ± 0. 25,0. 99 ± 0. 15,0. 98 ± 0. 23,0. 99 ± 0. 18),and the differences were significant(F ＝620. 099,580. 796,1 125. 225,645. 082,all P ＜0. 05);the IL-1β mRNA relative expressions in epilepsy group (2. 32 ± 0. 15,2. 90 ± 0. 18,4. 18 ± 0. 16,2. 74 ± 0. 07)were significantly increased compared with those of the melatonin group (1. 78 ± 0. 09,2. 35 ± 0. 11,3. 24 ± 0. 13,1. 78 ± 0. 16)and the control group(0. 97 ± 0. 13,0. 99 ± 0. 15,0. 97 ± 0. 23,0. 97 ± 0. 18),and the differences were significant(F＝267. 952,398. 767,1 140. 384,438. 962,all P ＜0. 05). Conclusions The NLRP3 inflamma-somes are activated in rat hippocampus with epilepsy induced by lithium-pilocarpine. NLRP3 inflammasome mediated inflammatory response probably involved in the pathogenesis of epilepsy. The melatonin may play a neuroprotective role by inhibiting expression of NLRP3 inflammasome.

Non-small-cell lung cancer (NSCLC), the most common type of lung cancer accounting for 85% of the cases, is often diagnosed at advanced stages owing to the lack of efficient early diagnostic tools. 5-Hydroxymethylcytosine (5hmC) signatures in circulating cell-free DNA (cfDNA) that carries the cancer-specific epigenetic patterns may represent the valuable biomarkers for discriminating tumor and healthy individuals, and thus could be potentially useful for NSCLC diagnosis. Here, we employed a sensitive and reliable method to map genome-wide 5hmC in the cfDNA of Chinese NSCLC patients and detected a significant 5hmC gain in both the gene bodies and promoter regions in the blood samples from tumor patients compared with healthy controls. Specifically, we identified six potential biomarkers from 66 patients and 67 healthy controls (mean decrease accuracy >3.2, P < 3.68E-19) using machine-learning-based tumor classifiers with high accuracy. Thus, the unique signature of 5hmC in tumor patient's cfDNA identified in our study may provide valuable information in facilitating the development of new diagnostic and therapeutic modalities for NSCLC.
