In the electroencephalography (EEG) monitoring of patients with hypoxic-ischemic encephalopathy, generalized periodic discharges are often monitored abnormal waveforms. When there are some features of generalized periodic discharges (e.g., frequency≥1.5 Hz or plus), it indicates that the patient is at high risk for seizures or has a poor prognosis. Compared with conventional EEG, the time of continuous EEG monitoring is longer, so the detection rate of these waveforms is higher. At present, scholars at home and abroad have studied these waveforms, but there is controversy about the significance of these waveforms. In this paper, the definition and characteristics of these waveforms and their significance in determining prognosis and guiding treatment in patients with hypoxic-ischemic encephalopathy are reviewed.

Objective:To investigate the clinical and electrophysiological characteristics of patients with sudden unexpected death of epilepsy (SUDEP).Methods:Using "epilepsy" as the keyword, the relevant cases entered from October 2011 to March 2012 were searched in the database of the Electroencephalogram (EEG) Monitoring Center, Xijing Hospital, the Air Force Military Medical University. Telephone follow-up was conducted for all confirmed epilepsy patients, and for the death cases confirmed by telephone follow-up, the patients identified as consistent with SUDEP diagnosis were included in this study based on their past medical history, clinical data, death details, etc, and their clinical and neuroelectrophysiological characteristics were summarized and analyzed.Results:Among the 1 232 patients who underwent 24-hour video-EEG monitoring during the study period, 354 patients were successfully followed up by telephone interview, of whom 17 patients were died (4.8%), 12 individuals met the diagnosis of SUDEP (7 men, 5 women). The duration of the disease in 9 patients exceeded 10 years. Eight cases presented with focal-bilateral tonic clonic seizures. Nine patients were treated with anti-seizure drug monotherapy. All the 24-hour video EEG of 12 patients were abnormal. There were 8 occasions when the EEG occipital α background rhythm slowed down compared with the standard frequency of peers or was dominated by slow waves. Interictal epileptic discharge (IED) located in temporal lobe were found in 12 EEG records, of which 9 EEG records were found with frontal IED. One of the 12 cases received 24-hour video EEG twice within 6 years, and his EEG background rhythm was significantly slower and the IED region was expanded compared with the first EEG record. At the third year after reexamination of EEG, SUDEP developed in this patient.Conclusions:SUDEP patients have a long course of disease and bilateral tonic-clonic seizure. The interictal EEG shows occipital slow α activity and temporofrontal epileptiform discharges, which may increase the risk of SUDEP.

Objective:To evaluate the effect and safety of monoclonal antibodies to calcitonin gene-related peptide and its receptor (CGRP-mAbs) on migraine.Methods:Database of PubMed, Embase, Cochrane, CNKI, Wangfang digital journals were searched for randomized controlled trials (RCTs) of CGRP-mAbs in treatment of migraine. Quality of enrolled literature was assessed by the software of Review Manager 5.3 and software of StataMP14 was employed to conduct meta analysis.Results:A total of 13 RCTs were included, including 6 218 adult migraine patients (experimental group: 2 679 patients, placebo group: 3 539 patients). Meta analysis suggested that CGRP-mAbs for preventive treatment of migraine significantly reduced the monthly migraine days from baseline (standardized mean difference (SMD)=-0.35, 95% CI-0.4--0.3) and monthly acute migraine-specific medication consumption from baseline (SMD=-0.38, 95% CI-0.43--0.32), as compared with placebo group. CGRP-mAbs for preventive treatment of migraine significantly increased the ≥50% reduction from baseline in migraine days per month ( RR=1.65, 95% CI 1.54-1.76). The adverse events were similar between the CGRP-mAbs group and placebo group ( RR=1.06, 95% CI 1.01-1.10). Conclusion:CGRP-mAbs are effective and safe for preventive treatment of migraine.

BACKGROUND:The methods to treat intertrochanteric fracture are controversial. A large number of clinical studies concern the therapeutic effects of several popular methods to repair intertrochanteric fracture, but these results lack of independence, and may have bias that cannot be measured in the variable and observational studies. Thus, relevant studies have been limited. OBJECTIVE:To compare the repair effects of proximal femoral nail anti-rotation, dynamic hip screw and total hip arthroplasty on intertrochanteric fracture in aged patients by meta-analysis. METHODS: Four electronic databases were searched, including Cochrane library, PubMed, Web of Science and Chinese BioMedical Literature Database, to colect al randomized controled trials concerning the treatment of intertrochanteric fractures in the elderly with proximal femoral nail anti-rotation, dynamic hip screw and total hip arthroplasty. Using meta-analysis of evidence-based medicine, X-ray exposure time, postoperative complication rate, postoperative bed time, postoperative wound infection rate, Harris hip scores, mean operation time, intraoperative blood loss, length of hospital stays and length of the incision were compared and evaluated. Standard and methodology quality of the trials were criticaly assessed and relative data were extracted. This study used the Review Manager 5.0 software provided by Cochrane colaboration network. RESULTS AND CONCLUSION:Twelve randomized controled trials with 1 454 patients were included. Significant differences in mean operation time, intraoperative blood loss, X-ray exposure time, postoperative complication rate, and postoperative bed time were detected between the proximal femoral nail anti-rotation and dynamic hip screw groups (P < 0.05). Significant differences in length of hospital stays, postoperative complication rate, and postoperative bed time were observed between the proximal femoral nail anti-rotation and total hip arthroplasty groups (P < 0.05). Significant differences in postoperative complication rate, postoperative bed time, and Harris hip scores were detectable between the dynamic hip screw and total hip arthroplasty groups (P < 0.05). These data confirm that proximal femoral nail anti-rotation was apparently better than dynamic hip screw and total hip arthroplasty in operation time, intraoperative blood loss, length of hospital stays, postoperative complication rate, and postoperative bed time. Dynamic hip screw was better than proximal femoral nail anti-rotation in X-ray exposure time. Total hip arthroplasty was better than dynamic hip screw and proximal femoral nail anti-rotation in length of hospital stays, postoperative complication rate and postoperative bed time.
