6.24 mmol/L) and sixty healthy persons in the health center of our hospital were investigated as hyperhpidemia group (Hyperlipidemias) and control group (Controls) respectively.Hyperlipidemias were given simvastatin 20 mg?d~(-1) for twelve weeks (Statins).Blood samples of ulnar vein were extracted from Statins at the end of twelve weeks as well as Controls and Hyperhpidemias at the beginning of the experiment. Blood serum,plasma and mononuclearcell were extracted and stored at a refrigerator of-80℃.The level of plasma angiotensinⅡwas detected by the method of radioimmunity.While the expression of RANTES mRNA and protein on mononuclearcell were assessed by real time reverse transcription polymerse chain reaction and Western blot respectively.Results①The plasma angiotensinⅡof Hyperlipidemias was higher than that of Controls [(92.13?22.03) vs (50.85?12.12),P

OBJECTIVETo estimate the feasibility of 16-multidetector spiral computed tomography (16-MDCT) on detecting coronary plaques in comparison with intravascular ultrasound (IVUS).

METHODSSixty-eight patients suspected of coronary heart diseases were examined by 16-MDCT, quantitative coronary angiography (QCA) and IVUS. Coronary stenosis was defined as lumen diameter reduction (DS) >or= 50%. Hounsfield units (HU) were used to determine different types of plaques: soft plaque (or= 120 HU).

RESULTSCompared to QCA, the sensitivity and the specificity for patients with DS >or= 50% were 91.8% (112/122) and 97.8% (556/568) respectively, the positive and negative predictive value were 90.3% (112/124) and 98.2% (556/566) respectively. In 96 plaques evaluated both by 16-MDCT and IVUS, 20 and 21 soft plaques, 37 and 36 fibrous plaques, 39 and 38 calcified plaques were identified by 16-MDCT and IVUS respectively. HU value of soft (11 +/- 36), fibrous (83 +/- 20), and calcified (292 +/- 80) plaques were significantly different (P < 0.05).

CONCLUSIONSNoninvasive 16-MDCT could correctly estimate coronary stenosis and coronary plaques compositions.

Virus-like particles (VLPs) are composed of multiple copies of one or more expressed recombinant viral structural proteins which spontaneously assemble into particles upon expression. VLPs are non infectious because they assemble without incorporating genetic material. VLPs have structural characteristics and antigenicity similar to the parental virus because they mimick the wild-type virus structure. Hence, they are recognized readily by the immune system which induces strong anti-viral immune responses to stop virus infection. VLPs have therefore shown dramatic effectiveness as candidate vaccines and diagnostic reagent for virus. Here, in order to provide reference to the research of influenza VLPs, we reviewed the current research progress of influenza VLPs, and discussed the characteristics associated with producing VLPs for influenza virus.

Schmallenberg virus (SBV), a novel orthobunyavirus, was first isolated in 2011. SBV preferentially infects the central nervous system of cattle and sheep and causes fever, diarrhea, a drop in milk yields, congenital malformations and stillbirths. Until June 2014, more than 200 scientific publications regarding SBV have been published. Although more than 20 articles on SVB were published in China, most of these articles provided only a brief introduction of the disease without fully discussing the associated disease characteristics. As a new disease, it has been made a focus of the National Research Center for Exotic Animal Diseases at the China Animal Health and Epidemiology Center. In this review, in order to provide a reference for research into SBV in China, we have reviewed the state of current research progress on the etiology, diagnosis and epidemiology of SBV, and vaccine development.

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 analyze the risk factors of colorectal cancer-related anemia.

METHODThe clinical data of 319 patients with colorectal cancer were retrospectively analyzed for the possible risk factors of tumor-related anemia including tumor location, clinical stage, clinical symptoms, pathology, gender, and age.

RESULTSOf these 319 cases, 141 (44.20%) had anemia. The incidence of anemia was 62.20% among patients with right hemicolon cancers (including caecum cancer), and was 23.82% among patients with rectal cancer and 36.23% among those with transverse descending or sigmoid colon cancer. Cardia insufficiency, melena, tumor location, T staging, hypoproteinemia were also found to be related with anemia. Anemia and hypoproteinemia were the risk factors for perioperative blood transfusion (odds ratio = 3.004, odds ratio = 8.356, respectively).

CONCLUSIONSThe colorectal cancer-related anemia is not associated with the clinical stage of the tumor, while cardiac insufficiency, melena, tumor location, tumor stage, and hypoproteinemia constitute the possible risk factors. Anemia and hypoproteinemia are the risk factors of perioperative blood transfusion.

OBJECTIVETo carry out expert survey for traditional Chinese medicine (TCM) syndrome characteristics of different clinical types of coronary artery disease (CAD).

METHODSBy using Delphi method, we carried out two rounds of nationwide expert surveys for modern TCM characteristics of syndrome elements and syndrome types of CAD.

RESULTSBased on expert consensus, qi deficiency, blood stasis, phlegm turbidity, qi deficiency blood stasis, and intermingled phlegm and blood stasis are common TCM syndromes for different clinical types of CAD. Of them, qi stagnation, blood stasis, phlegm turbidity, heat accumulation, cold coagulation, yang deficiency, deficiency of both qi and yang were more often seen in patients with unstable angina than in those with stable angina. Qi deficiency, yin deficiency, and deficiency of both qi and yin were less seen. We could see more excess syndrome and less deficiency syndrome (such as qi deficiency, yin deficiency, etc.) in acute ST-segment elevation myocardial infarction (STEMI) than acute non-ST-segment elevation myocardial infarction (NSTEMI). Qi deficiency, blood stasis, water retention, yang deficiency, phlegm turbidity, yin deficiency, Xin-qi deficiency, and qi deficiency blood stasis induced water retention are the most common TCM syndrome types of CAD heart failure (HF). Blood deficiency, yin deficiency, heat accumulation, deficiency of both Xin and Pi, deficiency of both qi and blood, deficiency of both qi and yin, yin deficiency and fire hyperactivity were more often seen in CAD arrhythmias.

CONCLUSIONSTCM syndrome distributions of different clinical types of CAD have common laws and individual characteristics. Results based on the expert consensus supplied evidence and support for clinical diagnosis and treatment of CAD.
