DEK protein's carboxy-terminal DNA-binding region(CBD)is a newly found DNA-binding domain of DEK,which contains several phosphorylation sites and has a close correlation with DEK protein's function in vivo and in vitro.Using prokaryotic expression system,the peptide of DEK protein's carboxy-terminal DNA-binding region(CDB)was expressed and purified.In detail,the CDB DNA fragment was constructed into pET-30a(+)vector,and E.coli BL21(DE3)competent cells were used as host cells.The fusion protein His-CBD was expressed by induction of IPTG and purified by Ni-NTA agarose.The result of SDS-PAGE showed that the molecular weight of the purified protein was about 10.7kDa.Electrophoretic mobility shift assay(EMSA)indicated that DEK-CDB prefered to bind to supercoiled form of DNA in vitro,it had similar character to the binding of whole length DEK protein with DNA.This suggested that the carboxy-terminal DNA-binding region of DEK protein might function on the binding of DEK protein to DNA partly.

To learn about the economic studies on traditional Chinese medicines in domestic literatures, in order to analyze the current economic assessment of traditional Chinese medicines and explore the existing problems. Efforts were made to search CNKI, VIP, Wanfang database and CBM by computer and include all literatures about economic assessment of traditional Chinese medicines published on professional domestic journals in the systematic assessment and quality evaluation. Finally, 50 articles were included in the study, and the systematic assessment and quality evaluation were made for them in terms of titles, year, authors' identity, expense source, disease type, study perspective, study design type, study target, study target source, time limit, cost calculation, effect indicator, analytical technique and sensitivity analysis. The finally quality score was 0.74, which is very low. The results of the study showed insufficient studies on economics of traditional Chinese medicines, short study duration and simple evaluation methods, which will be solved through unremitting efforts in the future.

Objective To determine the diagnostic value of anti-mutated citrullinated vimentin(anti- MCV)antibodies for rheumatoid arthritis(RA).Methods The anti-MCV were determined in 136 patients with RA,80 non-RA patients and 19 normal peoples.The diagnostic value of anti-MCV was assessed and compared with anti-CCP,AKA and RF.Results The sensitivity and specificity of anti-MCV in the 136 RA patients was 95.6% and 80.8% respectively,there was significanl difference between the test group and the control group(P

Objective To assess longitudinal segmental myocardial strain and displacement of left ventricle (LV) in patients with dual chamber pacing (DDD) using velocity vector imaging (VVI) and to explore the clinical application value of VVI in assessing left ventricular motion.Methods A total of 23 patients before and after DDD pacemaker implantation were enrolled in this study.The peak systolic strain and displacement of ventricular segments were measured with VVI and compared before and after pacemaker implantation.Results Compared to the values at the baseline,the strain and displacement of lateral,interventricular septum,anterior and posterior wall of LV in patients with pacing were significantly decreased.The strain,displacement of basal and mid segments with pacing were decreased as well(P＜0.01).The left ventricular strain and displacement in patients with pacing were significantly decreased than those of patients at the baseline(P＜0.05).Left ventricular longitudinal displacement before and after DDD pacing was significantly decreased from basal,mid to apical segments.But no significant difference was found in longitudinal strain from basal,mid to apical segments of LV.Conclusions (1) Left ventricular strain and displacement in patients with pacing were different between those before and after DDD pacing.(2) VVI can accurately assess left ventricular strain and displacement in patients with DDD pacing,and can become a powerful mean to assess the regional myocardial function.

Objective To study the efficacy and safety of tacalcitol combined with monochromatic excimer light (MEL) 308 nm vs MEL 308 nm monotherapy in treating vitiligo.Methods Thirty-eight pa- tients with vitiligo were enrolled in the single-blind clinical trial,using plabebo-treated lesions in the same patient as controls.Contralateral or nearby lesions were randomly selected to be treated by either tacalcitol or placebo.All lesions were treated weekly with MEL 308 nm,for a total of 12 sessions.Patients were ex- amined at monthly intervals.The mean number of sessions and the cumulative dosage for initial and excel- lent repigrnentation were calculated.Results Thirty-five patients were evaluated.The mean?SEM cumu- lative dose and number of MEL exposures for initial repigmentation,respectively,were 4.27?3.59 J/cm~2 and 4.89?3.16 on tacalcitol-treated site,5.36?4.12 J/cm~2 and 5.69?3.29 on placebo-treated site,re- spectively (both P＜0.05).For excellent repigrnentation,the cumulative dose and number of exposures were 7.72?5.64 J/cm~2 and 7.79?4.70 respectively on tacalcitol-treated site,and 8.18?4.87 J/cm~2 and 8.4?3.92 respectively on placebo-treated site (both P＞0.05).Treatment with tacalcitol resulted in a sig- nificantly higher percentage (71.4% vs 54.3%) of repigmentation than that with placebo.Conclusions Our results show that MEL 308 nm is safe and effective for the treatment of vitiligo.Additionally,concur- rent topical tacalcitol potentiates the efficacy of MEL 308 nm in the treatment of vitiligo;this combination achieves more rapid pigmentation with a lower total MEL dosage.

Objective To study the changes of somatostatin(SOM) in plasma and cerebrospinal fluid (CSF) of children with convulsive diseases.Methods Sixty-seven children with convulsive diseases were studied as following:obtaining the samples of plasma in the 1st and 7th day after being in hospital,and the samples of CSF in the 1st after being in hospital.We investigated the changes of SOM in plasma and CSF with radioimmunoassay(RIA).Results 1.Convulsive group:the concentration of SOM in plasma in the 7th day(29.47?9.40 ng/L) was significant lower than that in the 1st day(39.23?11.00 ng/L)(t=21.530 P0.05).The concentration of SOM in plasma in the 1st day in control group was(19.58?6.04) ng/L.There were significant differences in convulsive group and encephalitis group without convulsion, control group(t= 6.847,7.921 P

OBJECTIVE: To investigate the relation between injury time and the expression of cytochrome c oxidase subunit VIc (COX6C) mRNA in skeletal muscle of rat after contusion. METHODS: A total of fifty-four SD rats were divided into the control group and the contusion groups (0.5, 1, 6, 12, 18, 24, 30, and 36 h after contusion), randomly. The contusion model was established by free fall drop of gravity hammer. At corresponding time point after contusion, the regular histology was examined and expression level of COX6C mRNA was tested by real-time PCR after extraction of total RNA from the tissues. RESULTS: The main pathological features of 6 h after injury included edema and hemorrhage in myocytes with no inflammatory cells found. After 6 hours, the findings included myocyte degeneration and necrosis, inflammatory cells infiltration, and fibrous connective tissue proliferation in the contused zone. The expression level of COX6C mRNA was higher than that of the control group within 6 h after contusion. The expression level was lower than that of the control group from 6-36 h after contusion. CONCLUSION The level of COX6C mRNA expresses in a regular way after contusion. It may be useful for estimating wound age in combination with the results of pathological features.
