RESUMO

The present study aimed to examine the functional and molecular effects of miR­128 in epilepsy, in order to investigate its potential protective mechanisms. Firstly, miR­128 expression in rats with lithium chloride­induced epilepsy was demonstrated to be increased compared with the control rats. Subsequently, results from an in vitro epilepsy model demonstrated that overexpression of miR­128 promoted nerve cell apoptosis, increased the protein expression of tumor protein p53, BCL2 associated X (Bax) and Cytochrome c, and enhanced caspase­3/9 activity, whereas it suppressed the protein expression of sirtuin 1 (SIRT1). In addition, these alterations may be reversed by the downregulation of miR­128. Furthermore, treatment with CAY10602, a SIRT1 agonist, reduced the effects of miR­128 on nerve cells in vitro. Treatment with pifithrin­ß hydrobromide, a p53 inhibitor, was additionally able to mitigate the effects of miR­128 in vitro. In conclusion, the present findings indicated that anti­miR­128 may exert neuroprotective effects in epilepsy, through the SIRT1/p53/Bax/Cytochrome c/caspase signaling pathway.

RESUMO

BACKGROUND: To explore the incidence and risk factors, including type of seizures for post-traumatic epilepsy (PTE) after severe traumatic brain injury (TBI). SUBJECTS AND METHODS: This was a retrospective follow-up study of patients discharged from Liaocheng People's Hospital between March 2011 and June 2015 with a diagnosis of post-traumatic seizures. Risk factors for PTE were evaluated in 68 inpatients by using Kaplan-Meier curves and the Cox model. RESULTS: Complete clinical information was available for 68 patients. A total of 54 cases (79.4%) were diagnosed as presenting with PTE, occurring from 10 days to 179 months after severe TBI. Nineteen out of 54 cases (35.2%) had been defined as PTE within the first 6 months after the trauma, 17 cases (31.5%) within 7-12 months, 8 cases (14.8%) within 13-24 months, 2 cases (3.7%) within 25-36 months, and 8 cases (14.8%) within 37-179 months after the TBI. The Kaplan-Meier curves demonstrated that simple partial seizures, surgical treatment, and onset of seizures occurring within 6 months after injury were associated with PTE. CONCLUSIONS: The Cox model indicated that, for patients aged >34 years at the time of injury, the PTE risk was 2.55 times greater than for those aged ≤34 years. In addition, simple partial seizures, surgical treatment and onset of seizures occurring within 6 months after injury were significant risk factors for the development of PTE.

RESUMO

INTRODUCTION: Although functional recovery and survival after ischemic infarction seem to improve in patients with prior transient ischemic attack (TIA), little is known about the role of characteristics of prior TIA in subsequent cerebral infarction. Thus, the objective of this study was to explore how the characteristics of prior TIA have a neuroprotective effect on patients with ischemic stroke. MATERIAL AND METHODS: A total of 221 patients admitted consecutively to a primary care center for first-ever ischemic stroke were divided into two groups on the basis of the presence or absence of prior TIAs. The initial NIHSS modified Rankin Scale was used to measure the severity and disability after the stroke. Subgroups were based on the TIA duration (< 10 min, 10 to 60 min, and > 60 min), TIA frequency (1 time, 2-3 times, more than 3 times), and the interval of stroke (< 1 week, 1-4 weeks, > 4 weeks). The severity of the neurologic picture on admission and functional disability after stroke were compared between patients with and without TIAs and subgroups as well. RESULTS: A total of 132 (59.73%) of the 221 patients had prior TIAs before stroke. Risk factors and the initial clinical picture did not differ between patients with or without TIAs. Patients with prior TIA had a more favorable outcome than those without TIA (59.09% vs. 43.82%), and a significant difference between the two groups was observed (χ² = 4.976, p = 0.026). Furthermore, neurological outcome in patients with prior TIA lasting for 60 min, less than 3 times and shorter intervals within 4 weeks was significantly different from that in the non-TIA group (p < 0.05). CONCLUSIONS: Prior transient ischemic attacks may have a neuroprotective effect on the subsequent ischemic stroke, and this effect might be affected by the characteristics of TIAs. Patients with TIAs of low frequency, short duration and short interval are considered to have better neurological outcomes.

RESUMO

BACKGROUND: To extract, purify and identify the active constituents in ethanol extract of Radix Salviae Miltiorrhizae, and to analyze the protective effects of tanshinone IIA on cerebral ischemia-reperfusion injury in rats. MATERIALS AND METHODS: Radix Salviae Miltiorrhizae was extracted by ultrasonic extraction, effective parts were extracted by extraction method, compounds were isolated by preparative TLC and preparative HPLC, and structures of compounds were identified by (1)H NMR and (13)C NMR; the effects of tanshinone IIA on cerebral ischemia-reperfusion injury in rats were determined by establishing rat model of middle cerebral artery occlusion (MCAO). RESULTS: The experimental data show four compounds were isolated, namely tanshinone IIB, hydroxymethylene tanshinone, salvianolic acid B and 9"'-methyl lithospermate B. Tanshinone IIA could alleviate the symptoms of neurological deficit in rats, the neurological deficit alleviating effect became more obvious with the increase of dose; tanshinone IIA experimental groups could reduce the cerebral infarction size and brain water content in rats, different concentrations of tanshinone IIA could decrease the SOD content and increase the MDA content in the frontal and parietal cortices of ischemic hemisphere in the ischemia reperfusion group, the differences were statistically significant compared with the ischemia reperfusion group. CONCLUSION: Radix Salviae Miltiorrhizae has the protective effects on cerebral ischemia reperfusion injury in rats.

RESUMO

BACKGROUND: Although some studies evaluated the effectiveness of massage therapy for fibromyalgia (FM), the role of massage therapy in the management of FM remained controversial. OBJECTIVE: The purpose of this systematic review is to evaluate the evidence of massage therapy for patients with FM. METHODS: Electronic databases (up to June 2013) were searched to identify relevant studies. The main outcome measures were pain, anxiety, depression, and sleep disturbance. Two reviewers independently abstracted data and appraised risk of bias. The risk of bias of eligible studies was assessed based on Cochrane tools. Standardised mean difference (SMD) and 95% confidence intervals (CI) were calculated by more conservative random-effects model. And heterogeneity was assessed based on the I(2) statistic. RESULTS: Nine randomized controlled trials involving 404 patients met the inclusion criteria. The meta-analyses showed that massage therapy with duration ≥ 5 weeks significantly improved pain (SMD, 0.62; 95% CI 0.05 to 1.20; p = 0.03), anxiety (SMD, 0.44; 95% CI 0.09 to 0.78; p = 0.01), and depression (SMD, 0.49; 95% CI 0.15 to 0.84; p = 0.005) in patients with FM, but not on sleep disturbance (SMD, 0.19; 95% CI -0.38 to 0.75; p = 0.52). CONCLUSION: Massage therapy with duration ≥ 5 weeks had beneficial immediate effects on improving pain, anxiety, and depression in patients with FM. Massage therapy should be one of the viable complementary and alternative treatments for FM. However, given fewer eligible studies in subgroup meta-analyses and no evidence on follow-up effects, large-scale randomized controlled trials with long follow-up are warrant to confirm the current findings.

RESUMO

OBJECTIVE: To investigate the relationship between serum bilirubin and carotid atherosclerosis in patients with hypertension. PATIENTS AND METHODS: Carotid artery ultrasonography was performed in 198 patients (104 males, average age of 65.6+/-7.1 years) with hypertension. Serum levels of bilirubin and C-reactive proteins (CRP) were measured at the same time. RESULTS: Carotid atherosclerosis was detected in 133 patients, 87 of them had carotid artery plaque. The prevalence of stroke (20.3%) and myocardial infarction (13.5%) in the atherosclerosis group was higher than in the non-atherosclerosis group (9.2% and 6.2%, respectively, p<0.05). The average total serum bilirubin in the atherosclerosis group was lower than in the non-atherosclerosis group (12.8+/-1.3 vs 16.8+/-1.5 micromol/L, p<0.01), whereas the average serum of CRP was higher (4.1+/-1.1 vs 2.3+/-0.7 mg/L, p<0.01). After adjusting other factors such as age, total cholesterol, diabetes and systolic blood pressure, total serum bilirubin was negatively associated with carotid atherosclerosis in women and men, with odds ratios of 0.49 (95% CI, 0.28 to 0.71; p<0.01) and 0.66 (95% CI, 0.46 to 0.80; p<0.01). Serum CRP was positively correlated to carotid atherosclerosis, with odds ratios of 1.76 (95% CI, 1.36 to 2.04; p<0.01) in women and 1.95 (95% CI, 1.46 to 2.82; p<0.01) in men. CONCLUSION: Carotid atherosclerosis was associated with a high prevalence of stroke or myocardial infarction in hypertensive patients. Serum bilirubin was negatively associated with carotid atherosclerosis.
