[EX Q]: High sensitivity C-reactive protein (Hs-CRP) and adiponectin (APN) are two critical cytokines and exert inverse effects on atherosclerosis initiation and progression. The purpose of our study was to investigate the value of Hs-CRP and ANP ratio (Hs-CRP/APN ratio) on evaluating atherosclerosis progression.', "One hundred sixty consecutive participants underwent carotid intima-media thickness (CIMT) measured by ultrasound were enrolled and drawn fasting blood samples for plasma levels Hs-CRP and APN, serum levels of lipid profiles and fasting blood glucose evaluation. Other anthropometrics and clinical status were collected by questionnaire. All participants were divided into 4 groups according to the baseline Hs-CRP/APN ratio and underwent CIMT measurement every 6 months. CIMT increment and composite cardiovascular endpoints were compared after 24 months' follow-up.", "At baseline, body mass index (BMI), smoking, diabetic mellitus, usage of statins, Hs-CRP and APN independently correlated with Hs-CRP/APN ratio as analyzed by spearman rank correlation. Smoking, serum level of LDL-C, plasma level of Hs-CRP and Hs-CRP/APN ratio were positively correlated with CIMT while usage of statins and plasma level of APN were negatively correlated with CIMT as analyzed by multiple linear regression analysis. After 24 months' follow-up, the progression of CIMT was the most prominent in the fourth quartile of baseline Hs-CRP/APN ratio. In addition, the incidence of composite cardiovascular endpoint was also higher in the fourth quartile as compared to the other 3 lower quartiles.
[EX A]: Is increased Hs-CRP/adiponectin ratio associated with increase carotid intima-media thickness?

[EX Q]: Hostile neck anatomy is assumed to be associated with increased surgical risk for patients undergoing carotid endarterectomy (CEA) and is often considered a reason to choose carotid stenting or medical management. This retrospective case-control study evaluated whether, and how much, anatomically hostile necks represent a condition of higher surgical risk of early and late mortality and major or minor morbidity.', 'The data for 966 homogeneous CEA patients was prospectively entered in a computer database. Seventy-seven had a hostile neck anatomy due to previous oncologic surgery or neck irradiation, restenoses after CEA, high carotid bifurcation, or bull-like and inextensible neck. A case-control matched-pair cohort study considered sex, age (5-year intervals), and year of operation. Regional anesthesia was used for all operations for atherosclerotic stenosis >or=70%, conforming to the European Carotid Surgery Trial (ECST) in symptomatic and asymptomatic patients, at a single center and by one surgeon or under his direct supervision.', 'The hostile neck patients and the control group were matched for age, sex, carotid-related symptoms, degree of stenoses, and main risk factors for cardiovascular diseases. Intraoperative variables were substantially equivalent in the two groups; however, procedure length and clamping time were, respectively, about 22 minutes (P = .0001) and 7 minutes longer (P = .01) in the hostile neck group. Rates of postoperative mortality and neurologic events were equivalent. Peripheral nerve lesions were multiple and significantly more frequent in the hostile neck patients (21% with >or=1 cranial nerve lesion vs 7% of controls, P = .03), yet all were transient and limited to a few months. The subgroups of patients with hostile neck, restenoses, and bull-like inextensible necks required the longest operative and clamping time, and those with bull-like and high bifurcation had the most frequent cranial nerve dysfunctions. At the respective follow-up of 47 and 45 months, survival curves (P = .48) and the incidence of restenoses and fatal and nonfatal strokes were similar (5 and 4, respectively).

[EX Q]: This study aims to characterize the function of downregulated MicroRNA miR-205 in renal cell carcinoma (RCC), and show how the downstream zinc finger E-box-binding homeobox 2 (ZEB2) is negatively regulated by miR-205.', 'The expression of miR-205 was detected in RCC and adjacent non-tumor tissues using real-time polymerase chain reaction (PCR). The expression of miR-205 and ZEB2 was detected in RCC cell lines using real-time PCR. The luciferase reporter assay was used to assess ZEB2 as a target of miR-205. Protein levels of ZEB2, E-cadherin, and vimentin were measured by western blot after overexpression of miR-205 in ACHN cells. In vivo functions of miR-205 in ACHN cells were measured by MTT assays, migration and invasion assays, and flow cytometry.', 'MiR-205 was significantly downregulated in RCC samples and cell lines compared with matched non-tumor tissues and HK-2 cells, respectively. No significant difference was found in miR-205 expression between well differentiated and poorly to moderately differentiated groups or between phase I and phase II-III. ZEB2 was upregulated in RCC cell lines compared with expression in HK-2 cells. Upregulation of miR-205 expression caused the downregulation of ZEB2 and vimentin, and the upregulation of E-cadherin in ACHN cells. miR-205 also inhibited proliferation, migration, and invasion, and induced apoptosis of ACHN cells.
