Objective To explore the factor structure of the anxiety imagery characteristics questionnaire.Methods Through the literature review and expert group discussion,the initial anxiety imagery features questionnaire was created.The first questionnaire contained 49 items of anxiety imagery,which was answered by 106 imagery dialogue psychotherapists.After analysis of the items and exploratory factors,the formal questionnaire that contained 20 items of anxiety imagery characteristics was formed.The formal questionnaire was measured by 115 imagery dialogue psychotherapists,then,exploratory and confirmatory factor analyses were made.Results The exploratory factor analysis showed that four factors whose Eigen value were more than 1 were extracted from l0 items,including emotional panic,uneasy,tense muscles,and motor restlessness.Those four factors explained 54.39％ of the total variance.Confirmatory analysis showed that x2/df was 2.142 ; root mean square error of approximation (RMSEA) was 0.059 ; and comparative fit index (CFI),goodness-of-fit index (GFI),non-normed fit index (NNFI) and RSMEA was 0.912,0.935,0.896,and 0.057,respectively.Conclusions The four-factor structure was constructed by 10 items of anxiety imagery characteristics questionnaire.

Objective To investigate the efficacy and safety of carotid angioplasty and stenting for carotid stenosis in high-risk symptomatic NASCET-ineligible patients. Methods Twenty patients with symptomatic carotid stenosis at high risk ineligible for NASCET were treated with carotid angioplasty and stenting,12 of them were men,and 8 wre women,the patients ranged in age from 62 to76 years (mean age,69 years). Eleven patients had transient ischemic attack and 9 had cerebral infarction. Digital subtraction angiography showed that the degree of carotid stenosis in all patients was ＞ 70% (NASCET criteria). Among them,9 patients had unilateral carotid artery severe stenosis (2 had restenosis after endarterectomy),6 had bilateral carotid artery severe stenosis,5 had unilateral carotid artery occlusion with contralateral severe sentoses (1 had undergone cervical radiotherapy for nasopharyngeal carcinoma). The embolic protection devices,predilation,and self-expandable stents were used in all patients. Results The success rate of the procedure was 100%. The residual stenosis rate was ＜ 30%. The different levels of a transient decline in heart rates and blood pressure occurred in all the patients during the procedure. One patient was complicated with microembolic embolism. No ischemic stroke occurred in the remaining patients in the periprocedure. The postoperative examination with carotid ultrasound showed that the stenoses were improved significantly. No ipsilateral ischemic stroke and coronary ischemic events were observed at 1 and 3 months follow-up after the procedures. Conclusions Carotid artery stenting is less invasive,and the perioperative complications are fewer,The treatment of symptomatic carotid stenosis with high surgical risks is safe and effective.

Introduction:The 2010 targets of the China Hepatitis B Prevention Programme were a prevalence of hepatitis B surface antigen (HBsAg) less than 1.0% for children less than five years old and less than 6.0% for the total population. This survey assessed the prevalence of Hepatitis B infection in Lianyungang, Jiangsu province, China in 2009–2010.Methods:Multistage sampling was used with 2372 subjects among 17 selected villages. Blood specimen collection and testing by enzyme-linked immunosorbnet assay (ELISA) were completed using the following markers for hepatitis infection: HBsAg and antibody to HBsAg (anti-HBs); hepatitis B e antigen (HBeAg) and antibody to HBeAg (anti-HBe); and hepatitis B core antibody (total anti-HBc). The data were analysed with Epi Info, version 3.3.2.Results:The prevalence of HBsAg was 2.4% (95% Confidence Interval [CI]: 1.8–3.0; Adjusted Prevalence [AP] 2.9%); anti-HBs prevalence was 51.1% (95% CI: 49.1–53.1; AP 49.2%) and total anti-HBc prevalence was 41.7% (95% CI: 39.8–43.7; AP 45.5%). The prevalence of HBsAg and total anti-HBc positivity increased from young to older age groups, yet the prevalence of anti-HBs positivity decreased from young to older age groups (P< 0.001 for all). There was no difference in the prevalences of HBsAg and anti-HBs among females and males (P= 0.108 and 0.089), but females had a higher prevalence than males for total anti-HBc positivity (P< 0.001). Discussion: This survey showed that in 2010 the prevalence of HBsAg among children aged less than five years was lower than the national target of 1.0% and that the prevalence of HBsAg for the total population was lower than the national target of 6.0%.

OBJECTIVETo study the effect of Danshensu (DSS) and Ligustrazine (TMZ), the extracts of Chinese herbs for promoting blood circulation, on angiotensin II (Ang II) induced myocardial hypertrophy and its related genes, and to explore the mechanisms of inhibitory effect.

METHODSAdopting one-step method, the total RNA of myocardial cells was extracted by TRIzol reagent. Then the expression of ANP and beta-actin mRNA, as symbol of myocardial cells, were detected by RT-PCR.

RESULTSMolecular biological research showed that Ang II could significantly increase the expression of ANP mRNA in myocardial cells (P < 0.01), which could be significantly inhibited by Losartan (P < 0.01), both DSS and TMZ had the inhibitory effect (P < 0.05). Ang II could increase beta-actin mRNA expression in myocardial cells simultaneously, Losartan, DSS and TMZ could also significantly inhibit it (P < 0.05).

CONCLUSIONThe effective ingredients of Chinese herbs for promoting blood circulation, DSS and TMZ, have the effect of inhibiting the hyper-expression of ANP and beta-actin induced by Ang II, and preventing myocardial hypertrophy, therefore, it could be used to prevent and treat cardiomegaly.
