Thromboembolic events represent a clinically significant cause of neurological morbidity during the endovascular management of cerebral aneurysms. We have implemented an anti-thromboembolic regimen consisting of pre- and postoperative dual antiplatelet therapy, as well as postoperative anticoagulation using heparin and dextran. The aims of our study were to examine the effect of this regimen on thromboembolic rates during elective aneurysm coiling, and to elucidate risk factors associated with the development of thromboembolic events in this setting.', 'We conducted a retrospective review of patients who underwent elective intracranial aneurysm coiling between January 2005 and February 2012. The primary outcome of interest was the occurrence of a clinically significant peri-procedural thromboembolic event. Secondary outcomes included the occurrence of a central nervous system (CNS) or systemic hemorrhage.', 'During the study period, 312 patients underwent elective aneurysm coiling and six (2\xa0%) thromboembolic events occurred; three (1\xa0%) occurred in the group that received the anti-thromboembolic regimen (261 patients) and three (6\xa0%) occurred in the group that did not receive the regimen (51 patients), resulting in a statistically significant difference (P\u2009=\u20090.024). Both the presence of a hypercoagulable state (P\u2009=\u20090.014) and the lack of the anti-thromboembolic regimen (P\u2009=\u20090.043) were significantly associated with the occurrence of a thromboembolic event.

To examine the lipid profile in Chinese type 2 diabetic patients and their relationship with anthropometric parameters, glycaemic control and cardiovascular mortality.', 'A consecutive cohort of 562 newly referred patients with type 2 diabetes to a hospital-based diabetes centre were examined in 1996. Subjects treated with lipid lowering drugs at the time of referral were excluded. A total of 517 subjects were followed up over a mean (+/-SD) period of 4.6 +/- 0.9 years. Glycated haemoglobin (HbA1c), fasting insulin and lipid profile and anthropometric parameters were documented at the time of recruitment. Cardiovascular mortality, mainly due to coronary heart disease and stroke, was ascertained using death registry and review of hospital case notes in 2001.', 'Of the 517 subjects (mean age of 54.0 +/- 14.0 years), 42.6% were men. In this cohort, 63.3% of subjects were either overweight (BMI > or = 23 kg/m2) or obese (BMI > or = 25 kg/m2) using Asian criteria. The mean (+/-SD) total cholesterol (TC), LDL-Cholesterol (LDL-C), HDL-Cholesterol (HDL-C) and geometric mean (x// antilog SD) of triglycerides (TG) were 5.6 +/- 1.3 mmol/L, 3.6 +/- 1.1 mmol/L, 1.3 +/- 0.3 mmol/L and 1.46x//1.90 mmol/L respectively. TC and LDL-C correlated positively with HbA1c, HDL-C negatively with BMI and WC (waist circumference), while TG positively with HbA1c, BMI, WC and HOMA (insulin resistance estimated using the homeostasis model assessment). During the 4.6 years follow-up period, there were 61 deaths giving a total mortality rate of 11.4%, of which 15 (25%) were because of cardiovascular events. Apart from age and disease duration, logarithm of TG was significantly associated with increased risk of cardiovascular mortality (p = 0.049, relative risk = 2.97, 95% CI 1.00-8.77).

To explore the effects of continuous positive airway pressure (CPAP) treatment on the serum levels of associated inflammatory factors in patients with overlap syndrome (OS).', 'Seventy-four patients with obstructive sleep apnea syndrome (OSAS) or chronic obstructive pulmonary disease (COPD) or overlap syndrome (OS) were recruited from Department of Respirology and Affiliated Sleep Center of our hospital from March 2012 to September 2013. They were divided into OSAS (n = 25), COPD (n = 26) and OS (n = 23) groups according to the results of polysomnography (PSG) and spirometry. By enzyme linked immunosorbent assay (ELISA), the serum levels of C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α) and asymmetric dimethylarginine (ADMA) were measured and compared before and at Day 30 post-CPAP in OSAS and OS groups.', 'At pre-CPAP, there was no statistical difference in serum levels of CRP ((7.2 ± 6.6),(8.4 ± 6.8),(8.5 ± 7.9) mg/L) and TNF-α ((33 ± 13),(52 ± 34),(41 ± 33) ng/L) among OSAS, COPD and OS groups (all P > 0.05).However, serum ADMA level in OSAS group were significantly lower than those in COPD group ((0.50 ± 0.08) vs (0.71 ± 0.31) µmol/L, P = 0.002). Compared with before and at Day 30 post-CPAP, although no significant difference existed in serum levels of ADMA (all P > 0.05), at Day 30 post-CPAP there were significantly lower serum levels of CRP ((4.5 ± 4.2) and (5.5 ± 4.1) mg/L) and TNF-α levels ((31 ± 9) and (35 ± 24) ng/L) than those pre-CPAP in OSAS and OS groups respectively (all P < 0.05).No significant difference existed between OSAS and OS groups (all P > 0.05).
