Background: The effect of gene variants and their interactions on response to aspirin and clinical adverse outcomes after an acute ischemic stroke (IS) is not fully understood. The aim of this study was to investigate the association of aspirin-relevant gene variants and their interactions with clinical adverse outcomes in IS patients taking aspirin. Methods: A total of 14 variants from six genes encoding COX enzymes (COX-1, COX-2), platelet membrane receptors (TXAS1, P2Y1, P2Y12) and glycoprotein receptor (GPIIIa) were examined in 850 acute IS patients. Gene-gene interactions were analyzed using generalized multifactor dimensionality reduction (GMDR) analysis. All patients were followed up for 1 year after admission. Primary outcome was a composite of recurrent ischemic stroke (RIS), myocardial infarction (MI) and death. Results: The primary outcome occurred in 112 (13.5%) patients (81 RIS, 16 MI and 15 deaths). There were no significant differences in the frequencies of the genotypes of the 14 variants between the patients with and without primary outcome using single-locus analytical approach. However, there was significant gene-gene interaction among rs20417, rs1371097 and rs2317676. The high-risk interactive genotypes of rs20417, rs1371097 and rs2317676 were independently associated with primary adverse outcome of RIS, MI, and death after acute IS. Conclusion: The three-loci interactions are associated with sensitivity of IS patients to aspirin and aspirin-induced adverse clinical events. The combinatorial analysis used in this study may be helpful to elucidate complex genetic risk of aspirin resistance (AR).

The current study investigated the underlying dimensions of DSM-5 PTSD symptoms in an epidemiological sample of Chinese earthquake survivors. The sample consisted of 810 females and 386 males, with a mean age of 47.9 years (SD = 10.0, range: 16-73). PTSD symptoms were assessed using the PTSD Checklist for DSM-5, and alternative models were evaluated with confirmatory factor analysis. Results indicated that a six-factor model comprised of intrusion, avoidance, negative affect, anhedonia, dysphoric arousal, and anxious arousal factors emerged as the best fitting model. The current findings add to limited literature on the latent structure of PTSD symptoms described in the recently released DSM-5, and carry implications for further trauma-related research and clinical practice. © 2014 Elsevier Ltd.

Background Antiplatelet drugs are recommended for patients with acute noncardioembolic stroke. However, few randomized clinical trials have investigated the safety and efficacy of dual antiplatelet therapy for these patients. The aim of this study was to evaluate the effects of treatment with clopidogrel and aspirin (combination therapy) and aspirin alone (monotherapy) on neurologic deterioration, platelet activation, and other short-term outcomes in patients with acute large-artery atherosclerosis stroke. Materials and Methods Altogether 574 patients with acute (≤2 days) large-artery atherosclerosis stroke were randomly assigned to receive either combined clopidogrel and aspirin or aspirin alone. Platelet aggregation and platelet-leukocyte aggregation studies were performed at days 1 and 30. Primary outcomes including recurrent ischemic stroke, neurologic deterioration, periphery vascular events, and myocardial infarction were monitored. Safety endpoints were hemorrhagic episodes and death. Results The prevalence of neurologic deterioration and recurrent ischemic stroke were lower in patients in the combination therapy group than in those of the monotherapy group (3.52% versus 9.78% and 1.76% versus 6.29%, respectively). At day 30 of treatment, the platelet aggregations and platelet-leukocyte aggregates were lower in patients who were treated with clopidogrel and aspirin than in patients given aspirin alone (P <.001). Conclusions For patients with acute large-artery atherosclerosis stroke, treatment with clopidogrel and aspirin for 1 month provided significantly greater inhibition of platelet activity than aspirin alone. Thus, dual therapy can be safer and more effective in reducing ischemic stroke recurrence and neurologic deterioration. © 2014 by National Stroke Association.

Background We evaluated the efficacy of low-molecular-weight heparin (LMWH) relative to aspirin in preventing early neurologic deterioration (END), venous thromboembolism (VTE), and outcomes at 6 months. Methods Patients were randomly assigned to receive either subcutaneous enoxaparin 4000 anti-factor Xa IU/0.4 mL twice daily or oral aspirin 200 mg daily for 10 days. After day 10, all subjects received aspirin 100 mg once daily for 6 months. We assessed whether LMWH was superior to aspirin in preventing END and VTE within the first 10 days after index stroke and evaluated 6-month outcomes. Findings Of the total 1368 patients, 7.89% suffered from END, and 2.85% suffered from deep-vein thrombosis during the first 10 days, with a significance difference between the LMWH group and aspirin group (3.95%, 1.46% versus 11.82%, 4.23%, respectively). At 6 months, there was a significant difference in the frequency of good outcomes among patients over the median age of 70 years (LMWH 63.8% versus aspirin 44.6%). The benefit of LMWH was also significant in patients with symptomatic stenosis of the posterior circulation and basilar artery (75.2% and 82% for LMWH versus 40.5% and 48% for aspirin, respectively). Conclusions For patients with acute ischemic stroke, treatment with LMWH within 48 hours of stroke until 10 days later may reduce END and deep-vein thrombosis during the first 10 days. LMWH appears to have advantages over aspirin in certain subgroups, such as elderly patients and patients with posterior circulation and basilar artery stenosis. © 2014 by National Stroke Association.

The current study investigated the factor structure of posttraumatic stress symptoms assessed by the Impact Event Scale-Revised (IES-R) in a large sample of individuals from China who recently experienced a destructive earthquake. The results of the confirmatory factor analysis indicated that a four-factor structure (intrusion, avoidance-numbing, hyperarousal, and sleep disturbance) emerged as the model best fit in total sample, female and male subsamples, respectively. Moreover, multiple-group confirmatory factor analysis further demonstrated that the four-factor model was quite stable across sex. Implication and limitations for the results are discussed. © 2010 Elsevier Ltd.

Objectives: To investigate the association between toll-like receptor 9 (TLR9) single nucleotide polymorphisms (SNPs) and human papillomavirus (HPV) infection among Chinese Han women with cervical cancer. Methods: TLR9 -1486 and 2848 SNPs were investigated in patients with cervical cancer and controls using polymerase chain reaction (PCR)-restriction fragment length polymorphism. HPV16 E6 and E7 infections were assessed using PCR. Results: Of 120 patients with cervical cancer and 100 controls, there was a significant association between TLR9 2848 SNP and cervical cancer risk, but there was no such association with TLR9 - 1486 SNP. Frequency of the TLR9 2848 GA genotype was significantly higher in patients with cervical cancer than in controls. There was no statistically significant between-group difference in presence of HPV16 infection. Presence of HPV infection with TLR9 2848 (rs352140) GA/AA genotype increased the risk of cervical cancer 13.8-fold compared with the GG genotype. Conclusions: The TLR9 2848 G/A polymorphism in Chinese Han women was associated with increased risk of cervical cancer in the presence of HPV16 infection. Further studies are necessary to uncover the functional aspect of this TLR9 2848 polymorphism. © The Author(s) 2013.

Background: Cardiac rehabilitation (CR) is an evidence-based recommendation for patients with coronary artery disease (CAD). However, CR is dramatically underutilized. Telehealth interventions have the potential to overcome barriers and may be an innovative model of delivering CR. This review aimed to determine the effectiveness of telehealth intervention delivered CR compared with center-based supervised CR. Method: Medline, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library and the Chinese BioMedical Literature Database (CBM), were searched to April 2014, without language restriction. Existing randomized controlled trials, reviews, relevant conference lists and gray literature were checked. Randomized controlled trials that compared telehealth intervention delivered CR with traditional center-based supervised CR in adults with CAD were included. Two reviewers selected studies and extracted data independently. Main clinical outcomes including clinical events, modifiable risk factors or other endpoints were measured. Results: Fifteen articles reporting nine trials were reviewed, most of which recruited patients with myocardial infarction or revascularization. No statistically significant difference was found between telehealth interventions delivered and center-based supervised CR in exercise capacity (standardized mean difference (SMD) -0.01; 95% confidence interval (CI) -0.12-0.10), weight (SMD -0.13; 95% CI -0.30-0.05), systolic and diastolic blood pressure (mean difference (MD) - 1.27; 95% CI -3.67-1.13 and MD 1.00; 95% CI -0.42-2.43, respectively), lipid profile, smoking (risk ratio (RR) 1.03; 95% CI 0.78-1.38), mortality (RR 1.15; 95% CI 0.61-2.19), quality of life and psychosocial state. Conclusions: Telehealth intervention delivered cardiac rehabilitation does not have significantly inferior outcomes compared to center-based supervised program in low to moderate risk CAD patients. Telehealth intervention offers an alternative deliver model of CR for individuals less able to access center-based cardiac rehabilitation. Choices should reflect preferences, anticipation, risk profile, funding, and accessibility to health service. © The European Society of Cardiology 2014.

To establish a repeatable, simple, and effective model of rat crush injury and crush syndrome. A total of 42 female Sprague Dawley rats (2-month-old, (CS) so as to lay a foundation for further study on CS. weighing 160-180 g) were divided randomly into the control group (n=6) and experimental group (n=36). The rats of the experimental group were used to establish the crush injury and CS model in both lower limbs by self-made crush injury mould. The survival rate and hematuria rate were observed after decompression. The biochemical indexes of blood were measured at 2, 4, 8, 12, 24, and 48 hours after decompression. The samples of muscle, kidney, and heart were harvested for morphological observation. There was no treatment in the control group, and the same tests were performed. Seven rats died and 15 rats had hematuria during compression in the experimental group. Swelling of the lower limb and muscle tissue was observed in the survival rats after reperfusion. The liver function test results showed that the levels of alanine transaminase and aspartate aminotransferase in the experimental group were significantly higher than those in the control group (P < 0.05). The renal function test results showed that blood urea nitrogen level increased significantly after 2 hours of decompression in the experimental group, showing significant difference when compared with that in the control group at 12, 24, and 48 hours after decompression (P < 0.05); the creatinine level of the experimental group was higher than that of the control group at 4, 8, 12, and 24 hours, showing significant difference at 8, 12, and 24 hours (P < 0.05). The serum K+ concentration of the experimental group was higher than that of the control group at all time, showing significant difference at the other time (P < 0.05) except at 2 hours. The creatine kinase level showed an increasing tendency in the experimental group, showing significant difference when compared with the level of the control group at 4, 8, 12, and 24 hours (P < 0.05). The histological examination of the experimental group showed that obvious edema and necrosis of the muscle were observed at different time points; glomeruli congestion and swelling, renal tubular epithelial cell degeneration, edema, necrosis, and myoglobin tube type were found in the kidneys; and myocardial structure had no obvious changes. The method of the crush injury and CS model by self-made crush injury mould is a simple and effective procedure and the experimental result is stable. It is a simple method to establish an effective model of rats crush injury and CS.

To explore the effectiveness of Colorado 2 system in the stability reconstruction of sacroiliac joint fracture and dislocation in Tile C pelvic fracture. Between February 2009 and January 2011, 8 cases of Tile C pelvic fracture were treated with Colorado 2 system. There were 3 males and 5 females with an average age of 34.4 years (range, 22-52 years). Fractures were caused by traffic accident in 3 cases, by falling from height in 3 cases, and by crash of heavy object in 2 cases. According to Tile classification, 5 cases were classified as C1-2, 2 cases as C1-3, and 1 case as C2. The time between injury and operation was 5-10 days (mean, 7 days). After skeletal traction reduction, Colorado 2 system was used to fix sacroiliac joint, and reconstruction plate or external fixation was selectively adopted. The postoperative X-ray films showed that the reduction of vertical and rotatory dislocation was satisfactory, posterior pelvic ring achieved effective stability. All the incisions healed by first intention, and no blood vessel or nerve injury occurred. Eight patients were followed up 6-24 months (mean, 12 months). No loosening or breakage of internal fixation was observed and no re-dislocation of sacroiliac joint occurred. The bone healing time was 6-12 months (mean, 9 months). According to Majeed's functional criterion, the results were excellent in 5 cases, good in 2 cases, and fair in 1 case at last follow-up. Colorado 2 system could provide immediate stability of pelvic posterior ring and good maintenance of reduction effect, which is an effective method in the therapy of sacroiliac joint fracture and dislocation in Tile C pelvic fracture.
