摘要：Objective Atherosclerosis is increasingly recognized as an inflammatory disease. During recent years complement mediated inflammation has been shown to play an important role in coronary atherosclerosis disease (CAD). Abundant molecule and animal research suggest that complement may have a“dual function”in atherosclerosis: as C1q is involved in the removal of debris while anaphylatoxin C3a and C5a amplify inflammatory response. So we hypothesiszed that the relative ratio between C1q and C3a, C5a had a relationship with the extent of CAD which has not been evaluated in humans ever before。[第一段]

摘要：Objective Fibrinogen has been established to bean independent cardiovascular risk factor in general population but still controversial in patients with type 2diabetes diabetes (T2DM). More importantly, the data regarding the role of fibrinogen in cardiovascular outcomes in T2DM with stable coronary artery disease (CAD) is not available till now. Thus, we performed a prospective observational study on the association of fibrinogen withcardiovascularevents(CVE) in Chinese T2DM patients with stable CAD[第一段]

摘要：OBJECTIVE: To analyse the characteristics and therapies of patients with acute ischemic syndrome in China.　 METHODS: This study is part of the international multicentre registry for acute ischemic syndrome. Since April 1999, the data of patients admitted to designated hospitals with acute ischemic cardiac chest pain were collected by filling in Case Report Forms offered by the Canadian cardiovascular Collaboration. The main clinica l characteristics and in　hospital events of the patients were recorded.　 RESULTS: Fifteen hundred and nine cases of acute ischemic syndrome from 34 hospitals nationwide were enrolled in the registry (including unstable angina and non Q-wave myocardial infarction).The mean age of the patients was 62.3. Male dominance (62.2%) was noted. The percentages of patients with chest pain at presentation and abnormal ECG were 47.8% and 89.5%, respectively. The most common clinical diagnosis on admission was unstable angina, accounting for 91.3% of the patients and non Q-wave myocardial infarction (MI), accounting for the other 8.7%. During hospitalization, the following interventions were given: thrombolytic therapy in 50 cases (3.3%), coronary angiography in 528 cases (35.0%), percutaneous transluminal coronary angioplasty (PTCA) in 253 cases (16.8%) and coronary artery bypass graft surgery (CABG) in 62 cases (4.1%). Nitrate (oral or patch ) and anti-platelet therapy were used in 1460 cases (96.8%) and 1441 cases (95.5%), respectively. The incidence of in　hospital major events was 18.8%, in cluding 18 deaths (1.2%), with the most common causes being severe arrhythmias and sudden death.　 CONCLUSIONS: Patients with acute ischemic syndrome in China have mostly been diagnosed as cases of unstable angina. A relatively high PTCA rate but low CABG rate was noted in China. The most common cause of in　hospital death is severe arrhythmias or sudden death.

摘要：Background： Despite the rapid growth in the incidence of acute myocardial infarction （AMI） in China, there is limited information about patients＇ experiences after AMI hospitalization, especially on long-tern1 adverse events and patient-reported outcomes （PROs）. Methods： The China Patient-centered Evaluative Assessment of Cardiac Events （PEACE）-Prospective AMI Study will enroll 4000 consecutive AM I patients from 53 diverse hospitals across China and follow them longitudinally for 12 months to docunlent their treatment, recovery, and outcomes. Details of patients＇ medical history, treatment, and in-hospital outcomes are abstracted from medical charts. Comprehensive baseline interviews are being conducted to characterize patient demographics, risk factors, presentation, and healthcare utilization. As part of these interviews, validated instruments are administered to measure PROs, including quality of life, symptoms, mood, cognition, and sexual activity. Follow-up interviews, measuring PROs, medication adherence, risk factor control, and collecting hospitalization events are conducted at 1, 6, and 12 months after discharge. Supporting documents for potential outcomes are collected for adjudication by clinicians at the National Coordinating Center. Blood and urine samples are also obtained at baseline, 1 - and 12-month follow-up. In addition, we are conducting a survey of participating hospitals to characterize their organizational characteristics. Conclusion： The China PEACE-Prospective AMI study will be uniquely positioned to generate new information regarding patient＇s experiences and outcomes alter AMI in China and seiwe as a foundation for quality improveinent activities.

摘要：Since a typical mammalian cell contains only 200–300 picograms of proteins and the lack of a proteome amplification strategy[1],a practical and high-throughput approach for single-cell proteomics has long been awaited.A series of methods have been explored to make single-cell proteomics *** design of nanoPOTS and OAD chip-based processes minimizes sample preparation steps and volumes to reduce sample loss[2,3].

摘要：目的 比较针对2型糖尿病预防及治疗的4种筛查策略及随后予以的干预措施：（a）筛查2型糖尿病患者使其能接受早期检查及治疗，（b）筛查2型糖尿病和糖耐量受损患者，对糖耐量受损的人群予以生活方式干预以延缓或预防糖尿病的发生，（c）同（b）但予以药物干预措施，（d）不筛查。设计 成本效益决策分析建立在对概率的发展和评估基础上，是从筛查到死亡的综合性经济决策分析模型。研究对象 一组假设人群，筛查时年龄45岁，高于平均糖尿病风险水平。数据来源 电子书目数据库收录的已发表的临床试验和流行病学研究；补充数据分别来自英国和威尔士健康统计署、风险筛查（STAR）研究和ADDITION研究的Leicester部分。方法 建立一种决策树／Markov混合模型，以模拟每一种筛查策略的长期效用，包括临床和成本效益终点。该模型假设水平跨度为50年时间，其成本效益折损率为3．5％。采用敏感度分析以验证模型假设及确定哪种模型数据输入对结果的影响最大。结果 与不筛查策略比较，筛查2型糖尿病、筛查糖尿病和糖耐量受损并予以生活方式干预、筛查糖尿病和糖耐量受损并予以药物干预治疗3种策略，每获得一个质量调整生命年（QALY）估计所需成本分别为（每年成本效益贴现率为3．5％）14150英镑（17560欧元；27860美元）、6242英镑和7023英镑。在支付意愿阈值为20000英镑时，各主动筛查策略通过干预产生的成本效益概率分别为49％，93％和85％。结论 对年龄45岁、高于平均风险水平的人群进行2型糖尿病和糖耐量受损的筛查，并对糖耐量受损人群予以适当的干预似乎具有很好的成本效益。单独筛查糖尿病而不对糖耐量受损人群予以干预的策略具有的成本效益仍不确定，需要进一步研究确定早期检测糖尿病的作用。

摘要：背景：心力衰竭（heart failure，HF）这一综合征的表现多种多样。虽然医生可以根据患者射血分数（ejection fraction，EF）和舒张功能加以诊断，但是，目前有关社区人群心力衰竭特点的资料却寥寥无几，而且多数相关研究都是以医院为单位、有赖于实验室检查的回顾性研究。此外，鲜有研究采用标准化技术对患者舒张功能进行系统评价。目的：对社区心力衰竭患者的EF、心室舒张功能和脑型利钠肽（brain natriuretic peptide，BNP）水平进行前瞻性研究。主要观测指标：超声心动图测得的EF值和舒张功能、血BNP水平、6个月死亡率。设计、地点及参试者：于2003年9月10日至2005年10月27日在奥姆斯特德郡（Olmsted County）招募HF新发病例及陈旧病例（住院患者或门诊患者）。应用超声心动图测定EF和舒张功能，检测BNP水平。结果：共有556例参试者在确诊HF时接受了超声心动图检查。其中EF值正常（〉150％）者有308例（55％），多见于年长、女性和既往无心肌梗死病史的患者（P均〈0．001）。242例患者（44％）存在单纯舒张功能不全（即舒张功能不全，但EF值正常）。与EF正常的患者相比，EF降低的患者合并中、重度舒张功能不全的比例较高（风险比，1．67；95％可信区间[confidence interval，CI]，1．11～2．51；P=0．01）。EF降低以及舒张功能不全均与BNP水平升高独立相关。EF正常者及降低者6个月死亡率均为16％（对年龄和性别进行校正后风险比为0．85；95％CI，0．61—1．19；P=0．33）。结论：社区中半数以上的心力衰竭患者EF值正常，40％以上的患者存在单纯舒张功能不全。射血分数和舒张功能不全均与BNP水平升高独立相关。与EF降低的心力衰竭患者相似，EF正常的心力衰竭患者死亡率也较高。
