Serological surveillance of rubella in Europe: European Sero-Epidemiology Network (ESEN2)

Serological surveillance is an important resource to evaluate vaccine programmes, especially for diseases such as rubella, where a sub-optimal programme can lead to an increase in morbidity. A coordinated vaccine policy in Europe is needed and the aim of the European Sero-Epidemiology Network (ESEN2) is to standardise serological surveillance in 22 countries for eight diseases, including rubella.

An alpha-adrenergic blocker titrated by self-measured blood pressure recordings lowered blood pressure and microalbuminuria in patients with morning hypertension: the Japan Morning Surge-1 Study

BACKGROUND: The impact on microalbuminuria of strict treatment aimed at lowering of self-measured morning blood pressure using an adrenergic blockade is unclear. METHODS: We conducted an open-label multicenter trial, the Japan Morning Surge-1 Study, that enrolled 611 hypertensive patients, whose self-measured morning systolic blood pressure levels were more than 135 mmHg while taking antihypertensive drugs. These were randomly allocated to an experimental group, whose members received bedtime administration of 1-4 mg doxazosin (doxazosin group) or a control group whose members continued without any add-on medication (control group). The urinary albumin/creatinine ratio was investigated at the baseline and 6 months after the randomization. RESULTS: Both the morning and evening blood pressures and urinary albumin/creatinine ratio (-3.4 vs. 0.0 mg/gCr for urinary albumin/creatinine ratio; P < 0.001) were more markedly reduced in the doxazosin group than in the control group. This difference in the urinary albumin/creatinine ratio between the two groups was more marked in the patients with microalbuminuria (n = 238, -27.9 vs. -8.1 mg/gCr, P < 0.001). The reduction of urinary albumin/creatinine ratio was significantly associated with the use of doxazosin, and the change in all self-measured blood pressures (morning, evening, the average morning-evening), and these associations were independent of each other (P < 0.001). CONCLUSION: Adding a bedtime dose of an alpha-adrenergic blocker titrated by self-measured morning blood pressure in treated hypertensive patients with uncontrolled morning hypertension significantly reduced blood pressure and urinary albumin excretion rate, particularly in those with microalbuminuria.     

三氧化二砷体外抑制人宫颈癌Hela细胞生长机制的研究

采用MTT法观察三氧化二砷（AS2O3）对人宫颈癌Hela细胞生长抑制作用;膜联蛋白V（Annexin V）-异硫氰酸荧光素（FITC）＋碘化丙碇（PI）双参数流式细胞术（FCM）检测细胞凋亡情况,FCM测定细胞周期及增殖细胞核抗原（PCNA）表达。结果 AS2O3显著抑制Hela细胞生长增殖,且剂量—效应关系显著（r=0.98,P〈0.01）,其48 h的IC50值为5.59μmol/L。Hela细胞经AS2O3处理后可发生凋亡。AS2O3显著下调PCNA表达且使细胞周期阻滞于G2/M期（P〈0.01）。认为AS2O3在体外可显著抑制人宫预癌Hela细胞生长并诱导凋亡,其机制可能与阻滞细胞周期及降低PCNA蛋白表达有关。

房间隔缺损封堵术前后心肌损伤的变化

目的:探讨房间隔缺损(ASD)患者介入治疗前后心肌肌钙蛋白I(cTnI)的变化规律。方法:42例ASD患者(ASD组)、16例诊断性导管介入的先天性心脏病患者(诊断性导管介入组)用酶联免疫吸附(ELISA)法检测介入前后不同时间点血清cTnI的水平。结果:所有患者术前血清cTnI水平处于正常值范围内;术后即刻、4 h及24 h,ASD组较术前升高,诊断性导管介入组与术前无差异,两组间有显著统计学意义(P<0．01);72 h两组间无显著统计学意义(P>0．05)。结论:ASD的介入治疗引起可逆性的心肌微损伤,是一种安全、有效、创伤小的方法。     

Changes of Lipid Profile and C-Reactive Protein after Withdrawal of Xuezhikang,an Extract of Cholestin,in Patients With Stable Angina Pectoris

Lipid-lowering therapy using HMG-CoA reductase inhibitors (statins) has been shown to assist in the prevention of cardiovascular events in many clinical trials[1-3]. Statins may also have an abundance of pleiotropic effects[4-7]. C-reactive protein (CRP),…     

CA125、CEA、LDH、GLU、TBAb检测在胸腔积液中的价值

目的探讨胸腔积液患者胸腔积液CA125中CA125、CEA、LDH、GLU、TBAb这五项指标在胸积液性质鉴别诊断中的实用价值。方法将不同病因的胸腔积液患者115例分为结核性渗出液54例，恶性渗出液32例，化脓性渗出液29例。平行检测患者胸腔积液CA125中的五项指标。结果结核性胸腔积液CA125组TBAb（96．3％）阳性率明显高于恶性和化脓性胸腔积液CA125；化脓性胸腔积液CA125组LDH（1096±39．7）u／L明显高于恶性（594±34．6）u／L和结核性（638±31．9u／L）胸腔积液CA125组。化脓性胸腔积液CA125组GLU（2．91±0．56）mmol／L低于结核性和恶性胸腔积液CA125组；恶性胸腔积液CA125组CEA（87．3±12．6）ng／ml和CA125（98．3±29．6）u／ml明显高于化脓性和结核性胸腔积液CA125组。结论TBAb的检测对结核性胸腔积液CA125有较高的实用价值。LDH和GLU的联合检测对化脓性胸腔积液CA125有较大的价值。CA125和CEA的联合检测对恶性胸腔积液CA125有很大的实用价值。
