Objective To assess the application of spiral CT angiography in the diagnosis of Takayasu arteritis.Methods Vascular imaging features of three-dimensional CT angiography of 56 patients with Takayasu arteritis were analyzed retrospectively.Results The vascular imaging of all the patients were qualified for diagnosis.A total of 175 arteries were involved,including subclavian arteries (36.00%,63/175) with a high percentage of the left subclavian arteries (24.00%,42/175) ,common carotid arteries (29.71%,52/175) and renal arteries (10.86%,19/175) .The affected artery wall had varying degrees of concentric or eccentric thickening,and stenosis or occlusion of lumen was observed.Conclusion Threedimensional spiral CT angiography can make clear diagnosis of Takayasu arteritis,including the scope,extent and nature,and thus is worthy of clinical application.

OBJECTIVE:To study the actions of seabuckthorn oil emulsion against chronic atrophic gastritis and gastic ulcer in rats.METHODS:Chronic atrophic gastritis and gastric ulcer models were established in rats and mice and the antiulcer and anti-chronic atrophic gastritis actions of seabuckthorn oil emulsion were determined.RESULTS:Seabuckthorn oil emulsion could obviously prevent gastric ulcer and chronic atrophic gastritis induced by deoxycholic acid and stress and could decrease the index of acute gastric ulcer caused by ligature of pylorus in rats and could oppose the ulcer induced by indomethacin-ethanol significantly in mice.CONCLUSION:The results suggest that the antiulcer and anti-chronic atrophic gastritis actions of seabuckthorn oil emulsion may be related with its protection of the gastric mucosal barrier and neutralization of acid.

Objective To determine staging accuracy of double contrast-enhanced ultrasonography (DCUS)after neoadjuvant chemotherapy,and to evaluate effect during neoadjuvant chemotherapy for advanced gastric carcinoma(AGC).Methods A total of 29 patients with AGC diagnosed by endoscopy were examined and staged using ultrasound after taking oral contrast agent and bolus injection of SonoVue (DCUS)pre-and post-neoadjuvant chemotherapy.T-stage accuracy of post-neoadjuvant chemotherapy and pathological T status of postoperative were compared.All of the subjects were divided into two groups according to RECIST(Response Evaluation Criteria in Solid Tumors):chemotherapy benefit group(22cases,including:complete response 0 cases.partial response 14 cases,stable disease 8 cases)and progressive group(7 cases).The findings of DCUS of AGC tissues were assessed by auto-tracking contrast quantification(ACQ)software.The baseline intensity(BI)and peak intensity(PI)of gastric carcinoma tissues were measured automatically,and the enhanced intensity(EI)of gastric carcinoma tissues was calculated manually(EI =PI-BI).The quantitative analysis findings of DCUS of each patient pre-and postneoadjuvant chemotherapy between two groups were compared adopting repeated measures method.Results The overall accuracy of T staging in AGC patients after neoadjuvant chemotherapy were 65.52％ by DCUS,and 0,42.86％and 92.86％respectively for T2 stage,T3 stage and T4 stage.The agreement of this method was weak between T-stage accuracy post-neoadjuvant chemotherapy and pathological T status of postoperative.The Kappa value was 0.33.The difference value of PI and EI between pre-and postneoadjuvant chemotherapy in AGC patients for benefit group was more than that in progressive group.The main effect of BI in AGC tissues between pre-and post-neoadjuvant chemotherapy was no significant difference between two groups(P＞0.05).Conclusions Restaging by DCUS after neoadjuvant chemotherapy in AGC patients was found to be inaccurate.However,the difference value of PI and EI between pre-and post-neoadjuvant chemotherapy in AGC tissues for benefit group was more than that in progressive group.Thus,the value of PI and EI by ICUS may be a useful clinical parameter with which to evaluate the effect during neoadjuvant chemotherapy and guide therapeutic regimen for AGC patients.

Objective To study the role of OIf-1/EBF associated zinc finger protein (OAZ),a transcription factor encoded by a positional systemic lupus erythematosus (SLE) candidate gene,in the function of mesenchymal stem cells (MSC) of SLE patients by silencing this gene.Methods OAZ mRNA levels of bone marrow MSC obtained from 5 SLE patients and 5 healthy controls were detected by real-time PCR.Bone marrow MSC obtained from 6 SLE patients were incubated with specific siRNAs for 3 days,then cells were harvested for OAZ measurement,Idl-3 and CCL2 mRNA levels were tested by real-time PCR,and levels of CCL2 were detected in culture supernatants using ELISA.Differences between groups were analyzed using t-test or MannWhitney test.Results ① OAZ mRNA levels of bone marrow MSC were significantly elevated in SLE patients (0.013±0.016) compared to healthy controls (0.001±0.000,P=0.009).② After OAZ silencing,the expression levels of OAZ,Id1,Id2 and ld3 mRNA were significantly decreased (△Ct 10.3±0.7,15.2±1.6,8.1±1.4,10.5±0.6 vs 8.7±0.7,14.1±1.2,7.1±1.5,9.8±0.6) (P all ＜0.05).③ Both the expression levels of CCL2 mRNA (△Ct 2.2±1.1 vs 3.0±1.1 ) and the levels of CCL2 protein in culture supernatants [(341±29) pg/ml vs (304±19) pg/ml] were significantly increased in OAZ silencing group comparing to those in the control group (P all ＜0.05).Conclusion OAZ gene expression is significantly elevated in bone marrow MSC of SLE patients.OAZ may affect autoantibody production in SLE patients by regulating CCL2 expression.

objective To study the role of anti-EBV antibody in the development of systemic lupus erythematosus(SLE).Methods Peripheral blood was obtained from 55 SLE patients and 29 normal controls,and anti-EBV-VCA IgG,IgA,IgM antibody was detected by enzyme-linked immunosorbent assay[ELISA).Totat RNA was extracted from peripheral blood of 33 SLE patients and 26 normal controls and then reverse transcribed into complementary DNA.Real-time PCR technique was used to determine gene expressions at the transcription level.Comparison of anti-EBV antibody level and interferon inducible gene expression was made between SLE Datients and normal controls by t-test.The associations between anti-EBV antibody level,lupus activitv and IFN inducible gene expression were analyzed by Spearman's correlation analysis.Results (1)The levels of anti-EBV antibodies in SLE patients were significantly increased as compared to those in the normal controls[IgG(41±6)vs(19±6)U/ml,IgA(15.4±1.8)vs(8.3±2.1)U/ml,IgM(7.8±1.0)vs(3.7±1.2)U/ml]cantly elevated in SLE Datients as compared to normal controls[IFN scores 11±13 vs 0±3](all P<0.05),but not correlated with the levels of anti-EBV antibody in patients(all P>0.05).Conclusion Anti-EBV antibody is overproduced in SLE patients but not associated with disease activity as well as the expression level of several major types of I IFN inducible genes,suggesting that EBV infection may not be a major factor mediating the activation of IFN pathway and consequently the exacerbation of SLE.

Objective To investigate the in vivo effects of allogeneic mesenchymal stem cells transplantation (MSCT) on OAZ signaling pathway in patients with systemic lupus erythematosus (SLE).Methods Isolated and expand human MSCs from bone marrow cells or umbilical cord of healthy donors were infused into SLE patients. Peripheral blood cells were collected from 10 pre-MSCT patients as well as 1 week and 4 week post-MSCT, and RNA was extracted and reverse transcripted to cDNA. mRNA expression levels of OAZ and Id1-3 were measured by using real-time PCR. Serum levels of IL-10, IL-12, IL-21, CCL2 and ANA were tested by ELISA. Relationships of the gene expression levels with levels of cytokines and ANA were analyzed. Results mRNA expression levels of OAZ, Id1 and Id3 gene in patients with SLE were significantly decreased at week 1(△C:12.4±1.1, 9.7±1.9, 9.7±1.9, 2.1±1.0) and at week 4 (△Ct:13.3±1.2, 10.4±1.5,10.8±1.2, 2.1±1.2) after MSCT when compared to those of the pre-MSCT (△Ct:11.0±0.9, 7.4±2.1, 7.8±2.1, 0.1±1.5 respectively, P all＜0.05). Levels of IL-10, IL-21 and ANA were significantly lower 4 week after MSCT than those before (P＜0.05); while level of CCL2 was higher than pre-MSCT (P＜0.05). Cytokines and ANA levels 1 week after MSCT were not differentially changed comparing to those of the pre-MSCT. Alteration of OAZ mRNA expression levels pre- and post-MSCT were negatively correlated with changes of ANA, IL-21levels and positively correlated with changes of IL-12/IL-10 and CCL2 levels. Conclusions The expression of genes involving in the OAZ signaling pathway is effectively reduced along with the alteration of several cytokines and ANA after allogeneic MSCT in SLE patients. OAZ signaling pathway may play an important role in MSCT treatment for SLE.

Objective To study the role of the expression levels of 5 type Ⅰ interferon (IFN)-inducible genes (LY6E, OAS1, OASL, MX1, and ISG15) in the diagnosis and disease activity evaluation of systemic lupus erythematosus (SLE). Methods Peripheral blood was obtained from 68 SLE patients, 50 patients with other connective tissue diseases and 26 normal controls, and total RNA was extracted and reverse transcribed into complementary DNA. Real-time PCR technique was used to determine gene expressions at transcription level. An IFN score for each individual was calculated according to the expression of 5 1FN genes. Comparisons of gene expression and IFN score were made among groups. The genes expression levels in patients with SLE were analyzed using receiver operative characteristic curve. The association between IFN scores and disease activity, as assessed by the SLEDAI scores and 24 h proteinuria, was analyzed using Spearman correlation analyses. Results ① The expression levels of MX1, OASL, OAS1, ISG15 and LY6E mRNA in SLE patients were significantly increased as compared with normal controls and disease controls (P all＜0.01 ).② IFN scores in SLE patients (17.9±29.1) were significantly increased as compared with normal controls (0±3.3)and disease controls (3.0±8.1) (P all＜0.01 ). ③ IFN scores area under the ROC curve (AUCROC) was 0.846. When The IFN scores reached 2.56, its sensitivity and specificity for the diagnosis of SLE were 93.1%and 78.3%, respectively. ④ Levels of IFN score was positively correlated with SLEDAI scores (r=0.256,P＜0.05) and 24 h proteinuria (r=0.337, P＜0.05). Conclusion The 5 IFN-inducible genes are highly expressed in SLE patients. IFN score level is valuable for the diagnosis of SLE and a high IFN score is usually associated with an elevated disease activity.

Objective To understand the causes and the ratio of cause constituents in children with chronic cough in Beijing. Methods Patients with chronic cough treated at respiratory clinic of the Children' s Hospital Affiliated to Capital Institute of Pediatrics from May 2009 to April 2011 were included in this study. Etiologic diagnostic procedure suggested for children by the Subspecialty Group of Respiratory Diseases,the Society of Pediatrics,Chinese Medical Association in 2008 was implemented to manage the patients. After three - month follow - up,the etiological data was analyzed. Results Totally 213 patients with chronic cough aged 1. 1 to 14. 0 years old were enrolled,inclu-ding 40 cases(18. 8% )aged≤3 years old,134 cases(62. 9% )aged ﹥ 3 to 6 years old,and 39 cases(18. 3% ) aged ﹥ 6 years old. The majority of patients with positive allergen tests were sensitized to inhaled allergens. One child had positive result in 24 - hour esophageal pH monitoring,but his cough didn't respond well to the specific treatment for gastroesophageal reflux,so he wasn't diagnosed as gastroesophageal reflux cough. The 4 leading causes of the 213 pa-tients with chronic cough were cough variant asthma(CVA)in 92 cases(43. 2% ),CVA associated with upper airway cough syndrome(UACS)in 57 cases(26. 8% ),UACS in 28 cases(13. 2% ),respiratory infection and post - infec-tion cough(PIC)in 26 cases(12. 2% ),while other causes were found in 8 cases(3. 7% ),and unknown etiology in 2 cases(0. 9% ). The incidence of CVA ranked top 1 in all the 3 age groups,followed by PIC in ≤3 years old group, while CVA associated with UACS in the other 2 age groups. Conclusions CVA,CVA associated with UACS,UACS and PIC were the 4 leading causes for children with chronic cough in Beijing. Children in different age groups had dif-ferent constituents ratio of causes of chronic cough.
