大量证据显示随机对照临床试验(randomised controlled trial,RCT)的报告质量不理想。报告不透明,则读者既不能评判试验结果是否真实可靠,也不能从中提取可用于系统综述的信息。最近的方法学分析表明,报告不充分和设计不合理与对治疗效果产生评价偏倚有关。这种系统误差对RCT损害严重,而RCT正是以其能减少或避免偏倚而被视为评价干预措施的金标准。为了提高RCT的报告质量,一个由专家和编辑组成的工作组制定了临床试验报告的统一标准(Consolidated Standards of Reporting Trials,CONSORT)声明。CONSORT声明于1996年首次发表,并于2001年更新。声明由对照检查清单和流程图组成,供作者在报告RCT时使用。许多核心医学期刊和主要国际性编辑组织都已认可CONSORT声明。该声明促进了对RCT的严格评价和解释。2001年,在对CONSORT进行修订时,人们就已经清楚地认识到,解释和说明制定CONSORT声明的原理,有助于研究人员等撰写或评价临床试验报告。一篇CONSORT说明与详述文章于2001年同2001版CONSORT声明一起发表。2007年1月的专家会议之后,对CONSORT声明作了进一步修订并已发表,即"CONSORT2010声明"。这次更新对原版对照检查清单作了文字上的修改,使其更为明晰,并收入了与一些新近才认识到的主题相关的建议,如选择性报告结局产生的偏倚。说明与详述文件旨在加强人们对CONSORT声明的理解、应用和传播,这次也作了大量修订,对每一项新增或更新的清单条目的含义和增改理由进行了解释,提供了优秀的报告实例,还尽可能地提供了相关的经验性研究的参考文献。文中收入了若干流程图实例。"CONSORT2010声明"、其说明与详述文件,以及相关网站(***),对于改进随机临床试验报告必将有所裨益。

In this paper we present the science potential of the enhanced X-ray Timing and Polarimetry(eXTP) mission for studies of strongly magnetized objects. We will focus on the physics and astrophysics of strongly magnetized objects, namely magnetars, accreting X-ray pulsars, and rotation powered pulsars. We also discuss the science potential of eXTP for QED studies. Developed by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Sciences, the eXTP mission is expected to be launched in the mid 2020s.

AIM To compare post-percutaneous coronary intervention(PCI) radial artery occlusion(RAO) incidence between two conventional radial artery compression devices using a novel air-inflation *** One hundred consecutive patients post-PCI were randomized 1:1 to Safeguard or TR band compression devices. Post-radial sheath removal, each compression device was inflated with additional 2 m L of air above index bleeding point during air-filled device application and gradually down-titrated accordingly. RAO was defined as absence of Doppler flow signal performed at 24 h and at 6 wk post-PCI. Patients with missing data were excluded. Statistical significance was defined as P f radial sheath inserted. No significant differences were observed between Safeguard Radial(n = 42) vs TR band(n = 42) in terms of age(63 ± 11 years vs 67 ± 11 years), clinical presentation(electives, n = 18 vs n = 16; acute coronary syndrome, n = 24 vs n = 26) and total procedural heparin(7778 ± 2704 IU vs 7825 ± 2450 IU). RAO incidence was not significantly different between groups at 24 h(2% vs 0%, P = 0.32) and 6 wk(0%, both).CONCLUSION Safeguard Radial and TR band did not demonstrate significant between-group differences in short-term RAO incidence. Lack of evidence of RAO in all postPCI patients at 6 wk follow-up, regardless of radial compression device indicate advantage of using the novel and pragmatic air-inflation technique. further work is required to more accurately confirm these findings.

Analysis of the frequencies of chromosomes carrying various classes of porcine endogenous retroviruses (PERVs) and combinations of these classes was performed in the swine species Sus scrofa L. by using maps constructed in two principal component coordinates. four population clusters can be recognized in the maps. Cluster 1 is formed by wild boars,cluster 2 by domestic meat breeds, cluster 3 by meat-and-lard (universal) breeds, and cluster 4 by miniature pigs. The maps indicate that modern domesticated swine meat breeds are the closest to the wild type. Meat-and-lard domestic swine breeds are more distant from wild boars, and miniature pigs are diverged the most. The maps showed that microevolution processes associated with PERV carriership frequency had two basic dimensions, or vectors: the vector of fat deposition variation and the “minus” selection vector (determination of commercial traits). Thus, PERVs may cause variation in pig physiology.

Background: The concomitant presence of intestinal parasite infections (IP) and tuberculosis (TB) has relevance. M. tuberculosis immune response is associated with type 1 T helper cell (Th1) while IP is associated with type Th2 cell. However, there are several contradictory reports on cytokine production under coinfection and this could be in association to the mycobacterial antigens used in the studies. Aim: To get insight into the effects of different M. tuberculosis-specific antigens (ESAT-6/CfP-10 and 38 kDa/CfP-10) in generating of appropriate cytokines on peripheral blood mononuclear cells of IPTB co infected patients. Method: ELISA assessed IfN-γ and other 16 cytokines production and plasm IgE. In 18 months, we documented demographic, economic, clinical characteristics and IP frequency in individuals from Brazil. Results: An overall 10/35 (28.5%) were IPTB co infected and 40/76 (52.6%;p = 0.024) asymptomatic intestinal parasite infected community controls (IPCC). Endo-limax nana (40%) and Entamoeba coli (22%), were the most nonpathogenic protozoan identified and Entamoeba histolytica, Giardia intestinalis, Ascaris lumbricoides and Strongyloides stercoralis were the pathogenic species (40%). IgE was higher in IPCC (p = 0.036). Cytokine profiles were significantly biased toward a Th2 type IL-5 (p = 0.001) and IL-13 (p = 0.033), pro-inflammatory GM-CSf (p = 0.019) and borderline lower IL-1β in IPTB, all associated with ESAT-6/CfP-10, while IL-7 was borderline lower, but 38 kDa/CfP-10 associated;as well as IL-8 higher (p fN-γ levels were similar to both antigens stimuli (p ≥ 0.208). Conclusion: Therefore, coin-cident IPTB coinfection did not exert a significant inhibitory effect in IfN-γ production in response to either of the two antigens, but the partial discrepancy in Th1/Th2 response, is associated with the antigen priming cells.
