[Objectives] A simple and reliable HPLC fingerprint method was developed for the identification of dried barks of Ilex rotunda and I. godajam. [methods] Nine batches of dried barks of I. rotunda,and seven batches of dried barks of I. godajam collected from different pharmacies and arboretums in different regions of China were used to establish fingerprints. The software Similarity Evaluation System of Chromatographic Fingerprints of Traditional Chinese Medicine( 2004 A Edition) was used to evaluate the fingerprints. [Results]The fingerprints of dried barks of I. rotunda and I. godajam were established. methodological study met the technical requirements of fingerprints. The similarities of the fingerprints of dried barks of I. rotunda and I. godajam were all more than 0. 8 and 0. 9 respectively. There were 31 and 28 common peaks in I. rotunda and I. godajam,which could be classified into two clusters by principal component analysis( PCA) and hierarchical cluster analysis. [Conclusions] The feasibility and advantages of used HPLC fingerprints were verified,and the results indicated that the HPLC fingerprint as a characteristic distinguishing method combining similarity evaluation,principal component analysis and hierarchical cluster analysis can be successfully used to identify the authenticity of dried barks of I. rotunda and I. godajam.

Background In China,lack of evidence remains a significant challenge for the national initiative to promote physical activity(PA).We aimed to quantify the beneficial effects of meeting or maintaining the recommended PA level[150 minutes per week(min/wk)of moderate PA or 75 min/wk of vigorous PA or an equivalent combination]on incident cardiovascular disease(CVD)among Chinese *** We included 100,560 participants without history of CVD from three cohorts in the Prediction for Atherosclerotic Cardiovascular Disease Risk in China(China-PAR)*** proportional hazards models were used to estimate hazard ratios(HRs)and 95%confidence intervals(CIs)for CVD events and its subtypes,including stroke,coronary heart disease,heart failure,and CVD *** During a median follow-up of 7.3 years(range:6–15 years),777,163 person-years and 4693 incident CVD events were *** with participants who were inactive at baseline,the multivariable adjusted HR(95%CI)of developing CVD was 0.74(0.69–0.79)for those who met recommended moderate to vigorous physical activity(MVPA)level at ***,the risk of CVD incidence was reduced with increment of MVPA(Ptrendkeeping active over the period of follow-up had a substantial lower risk of incident CVD with the HR(95%CI)of 0.57(0.43–0.77).Conclusions The findings demonstrated that meeting and maintaining the recommended MVPA level could reduce the cardiovascular *** adoption of the PA recommendations would have considerable health impacts to the Chinese population.

总氮冲击可影响污水厂的稳定运行和达标排放。采用32析因试验对规模为25 m3/d的CAST中试装置进行了现场研究,调节因子为污泥回流比和充水比,装置进水TN均值为该污水厂设计值的2.5倍,出水TN浓度为响应因子。在冲击负荷条件下,无应急调控措施的出水TN浓度升高(p<0.01),且达不到一级B排放标准。提升污泥回流比和减小充水比的应急调控措施可降低TN冲击负荷对出水TN值的影响(p<0.01),污泥回流比呈负效应而充水比呈正效应,且污泥回流比的效应值低于充水比。在6 h运行模式下采用应急调控措施的出水效果优于4 h运行模式的,若在微曝气阶段外加碳源可促进反硝化从而保证出水TN浓度达标。降低充水比和提高污泥回流比需统筹考虑污水厂的实时进水流量和污泥回流设备的工况,并结合曝气系统的工作模式和外碳源投加,以获得最佳的综合调控效果。

BACKGROUND: Because of critical organ shortage, transplant professionals have utilized living donor liver transplantation (LDLT) in recent years. We summarized our experience in adult-to-adult LDLT with grafts of right liver lobe by a modified technique. metHODS: From January 2002 to August 2005, 24 adult patients underwent living donor liver transplantation with grafts of the right liver lobe at West China Hospital, Sichuan University, China. Twenty-two patients underwent modi-Bed procedures designed to improve the reconstruction of the right hepatic vein and the tributaries of the middle hepatic vein by interposing a great saphenous vein ( GSV) graft and the anastomosis of the hepatic arteries and bile ducts. RESULTS: No severe complications and death occurred in all donors. In the first 2 patients, (patients 1 and 2), operative procedure was not modified. One patient suffered from 'small-for-size syndrome' and the other died of sepsis with progressive deterioration of graft function. In the rest 22 patients (patients 3 to 24), however, the procedure of venous reconstruction was modified, and better results were obtained. Complications occurred in 7 recipients including acute rejection (2 patients), hepatic artery thrombosis (1), bile leakage (1), intestinal bleeding (1), left sub-phrenic abscess (1), and pulmonary infection (1). One patient with pulmonary infection died of multiple organ failure (MOF). The 22 patients underwent direct anastomosis of the right hepatic vein to the inferior vena cava (IVC), 9 direct anastomosis plus the reconstruction of the right inferior hepatic vein, and 10 direct anastomosis plus the reconstruction of the tributaries of the middle hepatic vein by in-terpos-ing a GSV graft to provide sufficient venous outflow. Trifurcation of the portal vein was met in 3 patients. Venoplasty or separate anastomosis was performed. The ratio of graft to recipient body weight ranged from 0.72% to 1.17%. Among these patients, 19 had the ratio <1.0% a

采用规模为25 m3/d的CAST现场中试装置,通过32析因试验进行了应对有机冲击的调控技术研究,调控因子为充水比和污泥回流比,以进水COD值为污水厂设计进水COD值的2倍时中试装置的出水水质作为响应因子。冲击时出水COD浓度升高(p<0.01)且达不到一级B排放标准,但对出水氮、磷等指标的影响不显著。调节充水比和污泥回流比可降低冲击负荷对出水水质的影响(p<0.01),充水比呈正效应而污泥回流比呈负效应,且充水比的效应值高于污泥回流比。当充水比为15%时采用30%的回流比可保证出水水质达标,但当充水比为25%和35%时,需要70%的回流比才能保证出水水质达标。通过降低充水比和提高污泥回流比可应对有机冲击对CAST工艺运行的影响,但此调控策略需统筹考虑污水厂的实时进水量和污泥回流设备的工况,并结合曝气系统的工作模式,以获得最佳的综合调控效果。

大气细颗粒物(PM_(2.5))仍是我国空气质量持续改善的重大挑战.近年来,二次有机气溶胶(SOA)对PM_(2.5)的贡献日益凸显.因此,深入认识复合污染条件下SOA生成机制和影响因素可以为进一步降低PM_(2.5)提供重要理论依据.实验室模拟是深入认识SOA生成机制的关键途径,也是模式模拟参数化方案的可靠来源之一.主要综述了我国多污染物共存条件下典型人为源挥发性有机物(VOCs)的SOA生成研究进展,包括汽油蒸气VOCs、生物质燃烧VOCs和含氧VOCs形成SOA过程中,前体物浓度、芳香烃含量、无机气体、种子气溶胶和相对湿度(RH)等不同因素对SOA生成的影响;阐述了实际大气VOCs的SOA生成潜势及其影响因素,最后提出了目前在SOA机制研究方面存在的关键科学问题,并对未来的研究方向进行了展望.

目的探讨非糖尿病人群基线空腹血糖水平与动脉僵硬度进展的关联。方法本研究选取了在2010-2018年完成了两次臂踝动脉脉搏波传导速度(baPWV)测量且第一次baPWV测量时为非糖尿病的开滦研究队列人群作为观察对象。采用多元线性回归方法,分析基线空腹血糖对随访baPWV和随访期间baPWV进展的影响。结果符合纳入标准的观察对象16875人,其中男性10453人(61.9%)。观察对象基线(第一次baPWV测量)年龄(45.9±13.0)岁,baPWV(1439.0±309.3)cm/s;随访(第二次baPWV测量)年龄(49.6±13.3)岁,baPWV(1494.6±334.3)cm/s。观察对象baPWV进展值为(55.7±233.4)cm/s。在多元线性回归分析中,校正其他混杂因素后,发现基线空腹血糖水平与随访baPWV呈正向关联(P<0.05),基线空腹血糖水平每升高1 mmol/L,随访baPWV升高16.89 cm/s;在随访期内空腹血糖变化值每升高1 mmol/L,baPWV进展增加3.70 cm/s。结论非糖尿病人群的空腹血糖水平影响随访动脉僵硬度。随访期内空腹血糖水平升高是影响动脉僵硬度进展的因素。
