Objective To establish a suitable evaluation index system to track implementation effect of clinical research program.Methods Delphi method was used to creat the evaluation index system.The weighted average method was adopted to determine the weight of each index.Results After two rounds of expert consultation,twenty seven evaluation indices were selected,including three first-class indices,eight second-class indices and sixteen third-class indices,and the weight of each index was determined.Conclusions The evaluation index system reflects the purpose of tracking clinical research to a certain extent.This index system is simple and easy to be used.

Metabolic abnormalities were identified and carotid intima-media-thickness(IMT)was measured in 221 individuals at risk for metabolic syndrome(MS).The results indicated that IMT was significantly thicker in MS individuals than that in non-MS individuals(P＜0.01).And there was a tendency of progressive increase in IMT with increasing components of metabolic syndrome.

Emerging data indicated that HCV subverts the antiviral activity of interferon (IF); however,whether HCV core protein contributes to the process remains controversial. In the present study, we examined the effect of HCV core protein on interferon-induced antiviral gene expression and whether the effect is involved in the activation and negative regulation of the Jak/STAT signaling pathway. Our results showed that, following treatment with IFN-α, the transcription of PKR, MxA and 2'-5'OAS were down-regulated in HepG2 cells expressing the core protein. In the presence of HCV core protein,ISRE-dependent luciferase activity also decreased. Further study indicated that the core protein could inhibit the tyrosine phosphorylation of STAT1, whereas the level of STAT1 expression was unchanged.Accordingly, SOCS3, the negative regulator of the Jak/STAT pathway, was induced by HCV core protein. These results suggests that HCV core protein may interfere with the expression of some interferon-induced antiviral genes by inhibiting STAT1 phosphorylation and induction of SOCS3.

Coronary vasospasm is a rare diagnosis resulting in sudden arrhythmic cardiac arrest. We report a case of a healthy, non-smoking elderly woman resuscitated from arrhythmic cardiac arrest. She had persistent spontaneous coronary vasospasm, leading to right ventricular myocardial injury and failure, and shock. She responded quickly to intravenous normal saline bolus infusion, but had irreversible neurological sequelae. Additionally, she had atrial fibrillation preceding ischemic ventricular fibrillation, a rare finding in coronary vasospasm-related cardiac arrest. We suggest immediate coronary angiography of patients in sudden arrhythmic cardiac arrest with acute right ventricular failure for a prompt, accurate diagnosis and appropriate management of the coronary vasospasm.

OBJECTIVETo explore the neutralization capacities of different types of human serum to measles virus epidemic strains and vaccine strain.

METHODSNeutralization antibody (NT) to Shanghai 191 and measles virus isolates in 2005 were tested using acute and convalescent serum samples from diagnosed measles patients, children serum samples collected before and after vaccination and serum samples of migrant residents, from 3 different regions. Additionally, animal immune serum referring to vaccine strain and 3 epidemic strains were prepared and used to undergo crossing neutralization test with corresponding strains mentioned-above. Antigenic ratios were calculated.

RESULTSGMT value of NT of after-immune serum to vaccine strains was 50.82,1.86 times higher than that to MVi/ZJ/05/7 (GMT was 27.35), whereas GMT value of convalescent serum to MVi/ZJ/05/7 (GMT was 386.95) was obviously higher than that to vaccine strain (GMT was 1:151.83),and GMT value of migrant residents' serum in 3 regions to MVi/ZJ/05/7 were 2.22-4.17 times lower than that to vaccine strain. Meanwhile,the antigenic ratios between MVi/ZJ/ 99/1, MVi/ZJ/04/1, MVi/ZJ/05/7 and vaccine strain were found to be 4.28,5.24 and 5.66 respectively. Additionally,low NT titers to vaccine strain were found in patients' acute sera and GMT value was over 1:4.

CONCLUSIONThere were obvious differences on neutralization antibody of different types of serum to measles vaccine strain and epidemic strains which indicating the antigenic diversity of epidemic strains had influenced the protective effectiveness of vaccine antibody to epidemic strains. It was of significance to carry on research projects on the antigenic diversity and effectiveness of measles vaccine.

OBJECTIVETo explore the safety and effectiveness of endoscopic mucosal resection (EMR) in the treatment of colorectal polyps.

METHODEMR was applied in the treatment of colorectal polyps.

RESULTSA total of 3578 polyps in 2609 patients were all completely resected except 2 cases and the integrated rate of samples was 99.6%. Intra- and post-operation complications occurred in 22 cases(0.8%), including 7 intraoperative bleeding, 5 postoperative bleeding, and 10 thermal burn, which were cured by symptomatic treatment. A total of 1530 (58.6%) cases were followed-up with 3-12 months and no relapse was found in former place of excision.

CONCLUSIONEMR can be applied in resection of colorectal polyps effectively and safely.

To observe the serum samples and the anti-inflammatory effect of Tripterygium wilfordii in treating RA by using the pharmacokinetic-pharmacodynamic model, make a correlation analysis on concentration-time and effect-time curves, and explore RORγt, IL-17, STAT3, IL-6 mRNA transcriptional levels in rats by PCR. Methotrexate, tripterine and high-dose T. wilfordii could down-regulate RORγt, IL-17, STAT3, IL-6 mRNA transcriptional levels in AA rat lymph nodes. The study on PK-PD model showed correlations between inflammatory factors and blood concentration of T. wilfordii. T. wilfordii and its main active constituent tripterine could show the inflammatory effect and treat RA by inhibiting IL-17 cytokine.

OBJECTIVETo study serum levels of brain natriuretic peptide (BNP) in children with Kawasaki disease (KD) and the correlation between BNP levels and the heart function.

METHODSForty-three children with KD and thirty healthy children were enrolled. Serum levels of BNP were measured using ELISA. KD children received an echocardiographic examination, including measurements of left ventricular ejection fraction (LVEF), left ventricular shorten fraction (LVSF), cardiac index (CI) and left ventricular inflow velocity through the mitral annulus.

RESULTSMean serum level of BNP at the acute stage in children with KD was significantly higher than that at the recovery stage as well as the control group (p<0.01). The LVEF, LVSF and CI levels at the acute stage were significantly lower than those at the recovery stage in children with KD (p<0.05). The linear regression analysis showed that the BNP level was negatively correlated with the levels of LVEF, LVSF and CI (r=-0.63, -0.52, -0.53, p<0.05).

CONCLUSIONSThe serum BNP levels increase significantly in KD children at the acute stage, and are negatively correlated with the levels of LVEF, LVSF and CI. Measurement of serum BNP level is useful for the early diagnosis of KD.
