Immune thrombocytopenia (ITP) is an autoimmune disease caused by T-cell dysfunction. Recently, several studies have shown that a disturbed Th17/Treg balance contributes to the development of ITP. MicroRNAs (miRNAs) are small noncoding RNA moleculesthat posttranscriptionally regulate gene expression. Emerging evidences have demonstrated that miRNAs play an important role in regulating the Th17/Treg balance. In the present study, we found that miR-641 was upregulated in ITP patients. In primary T cells, overexpression of miR-641 could cause downregulation of its target genes STIM1 and SATB1, thus inducing a Th17 (upregulated)/Treg (downregulated) imbalance. Inhibition of miR-641 by a miR-641 sponge in primary T cells of ITP patients or by antagomiR-641 in an ITP murine model could cause upregulation of STIM1 and SATB1, thus restoring Th17/Treg homeostasis. These results suggested that the miR-641-STIM/SATB1 axis plays an important role in regulating the Th17/Treg balance in ITP. [ABSTRACT FROM AUTHOR]

Summary: Objective: China has the largest population of patients with epilepsy worldwide, which imposes a heavy burden on the public and health care systems. Several epidemiological surveys on epilepsy have been performed in China. Although these surveys grossly describe the prevalence and gap in treatment of epilepsy, the status of epilepsy centers is unclear. The number of epilepsy centers has increased substantially in recent decades. Therefore, a nationwide investigation of the scale and distribution, personnel, equipment, and epilepsy care capacity of each epilepsy center is of great value. Methods: In 2017–2018, a multicenter cross‐sectional survey was performed by the Commission on Standardized Development of Epilepsy Centers, China Association Against Epilepsy in 31 provinces, autonomous regions, and municipalities. The survey consisted of 74 questions divided into four sections: (1) overview, (2) personnel, (3) essential equipment and facilities, and (4) epilepsy care service capacity. The questions ranged from January 1, 2016 to December 31, 2016. The data were analyzed using descriptive statistics. Results: There were 358 epilepsy centers for the 1.38 billion national population in 2016. Three quarters were in the eastern and western regions, and >90% were in tertiary hospitals. There were 9688 doctors engaged in epilepsy care, and 4.8% of doctors and electrophysiological physicians/technicians passed the national test for electroencephalography technical accreditation. A total of 9667 patients underwent resective surgeries in 2016. There were 888 vagus nerve stimulation procedures and 275 deep brain stimulation procedures. Significance: This study is the first unique survey of epilepsy centers in China. Despite their rapid development, epilepsy centers cannot meet patients' needs at this stage. The results provide data‐based evidence for the formulation of policies related to epilepsy service planning. [ABSTRACT FROM AUTHOR]

TUMOR surgery ,FUNCTIONAL status - Abstract
Background: Surgery of parasagittal meningiomas (PSMs) is still technically challenging, for the balance between radical resection and preservation of venous circulation. In this article, we'd systemically introduce the technical nuances of a simplified strategy for radical resection of all types of PSMs. All the cases were operated by one single neurosurgeon from a single institution. Methods: Clinical charts of patients with PSMs between 2014 and 2020were retrospectively reviewed. A simplified classification method was adopted, which was based on the relationship between the tumor and superior sagittal sinus (SSS). Surgery aiming at radical resection and venous flow preservation was performed. Only in case of total occlusion of SSS, we performed tumor resection without reconstruction of the venous sinus. Results: Clinical data obtained in 55 consecutive patients (47 primary and 8 recurrent cases) were analyzed, among which 20 were with patent sinus, 27 were with partially occluded sinus and 8 were with completely occluded sinus. Forty-two (76.4%) and 13 patients (23.6%) had the same and improved functional status as compared to that of pre-operation, respectively. Four patients (7.3%) experienced transient neurological deterioration but improved to the normal level in the long-term follow-up. All patients achieved Simpson I/II radical resection. No patients suffered from post-operative recurrence in the follow-up duration of 27.05 ± 19.55 (2–91) months. Conclusion: Radical and safe resection of all types of PSMs is achievable and not difficult if the simplified surgical strategy mentioned in the article is adopted, no matter to which extent the sinus is invaded.

The roles of some long non-coding RNAs (lncRNAs) in intracranial aneurysm (IA) have been investigated in many studies. The aim of this study is to elucidate the mechanism of lncRNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1)/microRNA-143 (miR-143)/vascular endothelial growth factor-A (VEGFA) signal axis in vascular endothelial injury-induced IA. MALAT1, miR-143, and VEGFA expression in IA tissues and normal arterial tissues were detected. Matrix metalloproteinase 9 (MMP-9) in tissues, von Willebrand factor (vWF) in serum and tissues, and endothelin-1 (ET-1) in serum were detected. The modeled IA rats were injected with silenced or overexpressed MALAT1 for detecting vascular endothelial injury. Vascular endothelial cells from patients with IA were abstracted and transfected with silenced or overexpressed MALAT1 to verify the impacts of MALAT1 on cell viability and apoptosis. The connections among MALAT1, miR-143, and VEGFA were verified by online prediction, luciferase activity, and RNA-pull down assays. Overexpression of MALAT1 and VEGFA and poor expression of miR-143 were found in IA tissues. Downregulation of MALAT1 inhibited blood pressure, the expression of ET-1, vWF, and MMP-9, as well as the apoptotic index of vascular endothelial cells of rats with IA. Downregulated MALAT1 inhibited apoptosis and promoted viability of vascular endothelial cells in IA. MALAT1 bound to miR-143 and miR-143 targeted VEGFA. This study suggests that MALAT1 elevates VEGFA expression through competitive binding to miR-143, thereby boosting apoptosis and attenuating viability of vascular endothelial cells in IA.

The effects of microRNAs (miRNAs) have been identified in epilepsy (Ep) in recent years, our research was focused on the functions of miR-494 in Ep and its inner mechanisms. The Ep modeled rats induced by lithium chloride-pilocarpine were treated with agomir-miR-494 or RIPK1-siRNA. The pathology of rat hippocampal tissues was observed. Expression of miR-494, receptor-interacting protein kinase 1 (RIPK1) and nuclear factor-kappaB (NF-κB) p65 was assessed by RT-qPCR and Western blot analysis. The hippocampal neurons of epileptic rats were successfully modeled, which were transfected with miR-494 mimics or RIPK1-siRNA to determine neurons' proliferation ability and cell apoptosis. The target relation between miR-494 and RIPK1 was measured by bioinformatics website and dual luciferase gene reporter assay. The expression of miR-494 was reduced, while the expression of RIPK1 and NF-κB p65 was amplified in hippocampus of Ep rats. Elevated miR-494 repressed the expression of RIPK1 to ameliorate the hippocampal neuron injury, accelerate neuronal proliferation, and restrain neuronal apoptosis via inactivating the NF-κB signaling pathway, causing a deceleration of Ep development. Furthermore, amplified RIPK1 was able to reverse the amelioration of neuronal injury in Ep rats which was contributed by upregulated miR-494. We found in this study that elevated miR-494 repressed RIPK1, causing an inactivation of the NF-κB signaling pathway and acceleration of cell proliferation, and suppression of apoptosis of hippocampal neurons in Ep rats, thereby attenuating the neuron injury and Ep development. Our research may provide novel targets for the therapy of Ep. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Internal neurolysis (IN) is an effective surgical treatment for trigeminal neuralgia (TN) without neurovascular compression (NVC) or postoperative recurrence. However, the trigeminal nerve is directly manipulated during the procedure, and there is a high incidence of trigeminocardiac reflex (TCR). The aim of this study was to retrospectively analyze the outcome of IN and to explore its relationship with the occurrence of intraoperative TCR. Methods: Surgical and anesthesia records of 27 TN patients who underwent surgical treatment with IN at our department between March 2010 and September 2016 were retrospectively analyzed. Patients were divided into 2 groups on the basis of the occurrence of TCR during surgery, and clinical characteristics were compared. Pain intensity was assessed by the Barrow Neurological Institute (BNI) pain intensity score and BNI facial numbness score. Results: TCR was observed in 23 of 27 patients (85.2%); it manifested as obvious changes in mean arterial pressure and heart rate by at least 20% of the baseline values. Trigeminal nerve atrophy was found in 9 patients (33.3%). The immediate pain-free rate was 96.3%, and the "excellent" rate was 72.1% for follow-up, with a rate of numbness or hypesthesia of 97.1%. These outcomes were retrospectively compared between the TCR and non-TCR groups, and there was a nonsignificantly higher "excellent" rate in the TCR group than in the non-TCR group. Conclusions: This study demonstrated that IN is an effective treatment for TN without NVC and has a close relationship with intraoperative TCR. To our knowledge, this is the first research describing TCR during IN. [ABSTRACT FROM AUTHOR]

Objective: This study addressed the benefit of intraoperative magnetic resonance imaging (iMRI) compared with conventional neuronavigation-guided resection in patients with gliomas.Research Design and Methods: The Medline, PubMed, Cochrane, and Google Scholar databases were searched up to 26 September 2015. Randomized controlled trials (RCTs), two-arm prospective studies, and retrospective studies in patients with glioblastoma/glioma who had received surgical treatment were included.Main Outcome Measures: The primary outcome measures were the extent of tumor resection and tumor size reduction for using iMRI-guided or conventional neuronavigation-guided neurosurgery. Secondary outcomes included impact of surgery on 6 month progression-free survival (PFS), 12 month overall survival (OS) rates and surgical duration.Results: We found that iMRI was associated with greater rate of gross total resection (rGTR) compared with conventional neuronavigation procedures (3.16, 95% confidence interval [CI] 2.07-4.83, P < .001). We found no difference between the two neuronavigation approaches in extent of resection (EOR), tumor size reduction, or time required for surgery (P values ≥.065). Intraoperative MRI was associated with a higher rate of progression-free survival (PFS) compared with conventional neuronavigation (odds ratio, 1.84; 95% CI 1.15-2.95; P = .012), but the rate of overall survival (OS) between groups was similar (P = .799). Limitations of the study included the fact that data from non-RCTs was used, the small study population, and heterogeneity of outcomes across studies.Conclusions: Our findings indicate that iMRI more frequently resulted in more complete resections leading to improved PFS in patients with malignant gliomas.

Skeletal myoblast (SkMB) transplantation has been conducted as a therapeutic strategy for severe heart failure. However, arrhythmogenicity following transplantation remains unsolved. We developed an in vitro model of myoblast transplantation with 'patterned' or 'randomly-mixed' co-culture of SkMBs and cardiomyocytes enabling subsequent electrophysiological, and arrhythmogenic evaluation. SkMBs were magnetically labeled with magnetite nanoparticles and co-cultured with neonatal rat ventricular myocytes (NRVMs) on multi-electrode arrays. SkMBs were patterned by a magnet beneath the arrays. Excitation synchronicity was evaluated by Ca
2+ imaging using a gene-encoded Ca2+ indicator, G-CaMP2. In the monoculture of NRVMs (control), conduction was well-organized. In the randomly-mixed co-culture of NRVMs and SkMBs (random group), there was inhomogeneous conduction from multiple origins. In the 'patterned' co-culture where an en bloc SKMB-layer was inserted into the NRVM-layer, excitation homogenously propagated although conduction was distorted by the SkMB-area. The 4-mm distance conduction time (CT) in the random group was significantly longer (197 ± 126 ms) than in control (17 ± 3 ms). In the patterned group, CT through NRVM-area did not change (25 ± 3 ms), although CT through the SkMB-area was significantly longer (132 ± 77 ms). The intervals between spontaneous excitation varied beat-to-beat in the random group, while regular beating was recorded in the control and patterned groups. Synchronized Ca2+ transients of NRVMs were observed in the patterned group, whereas those in the random group were asynchronous. Patterned alignment of SkMBs is feasible with magnetic nanoparticles. Using the novel in vitro model mimicking cell transplantation, it may become possible to predict arrhythmogenicity due to heterogenous cell transplantation. J. Cell.

A fixed retractor is routinely used during surgery for vestibular schwannoma to maintain the surgical corridor; however, brain injuries can be caused by use of retractors. The aim of this study was to present strategies for retractorless surgery for giant vestibular schwannomas and compare retractorless surgery with traditional retractor-assisted surgery to illustrate feasibility and potentially superiority of retractorless surgery. Clinical data of 61 patients with giant (≥4 cm diameter) vestibular schwannomas undergoing craniotomy were retrospectively analyzed. Patients were divided into 2 cohorts: 1) 35 patients with traditional retractor surgery performed between June 2016 and July 2017; 2) 26 patients with retractorless surgery performed between June 2016 and July 2018. Duration of operation, intraoperative blood loss, extent of resection, rate of retention of facial nerve function, postoperative brain injury rate, intracranial infection rate, hospitalization time, and grade of facial nerve function were compared between the 2 groups. The incidence of postoperative brain injury was 3.84% in the retractorless surgery group, which was significantly lower compared with the traditional retractor surgery group (22.86%) (P < 0.05). No significant differences were found regarding the other characteristics compared. Through appropriate comprehensive measures, retractorless surgery for giant vestibular schwannomas is an achievable goal. This procedure can reduce the incidence of postoperative brain injury with satisfactory tumor resection. [ABSTRACT FROM AUTHOR]

• We determined the correspondence between the thalamus and the cortex. • The anisotropy of thalamocortical fiber bundles in patients generally declined. • The abnormalities may be related to damage to the myelin sheath of nerve fibers. • The longer the disease duration, the more serious the damage. Epilepsy is one of the most common diseases of the nervous system. Approximately one-third of epilepsy cases are drug-resistant, among which generalized-onset seizures are very common. The present study aimed to analyze abnormalities of the thalamocortical fiber pathways in each hemisphere of the brains of patients with drug-resistant generalized epilepsy. The thalamocortical structural pathways were identified by diffusion tensor imaging (DTI) in 15 patients with drug-resistant generalized epilepsy and 16 gender/age-matched controls. The thalami of both groups were parcellated into subregions according to the local thalamocortical connectivity pattern. DTI measures of thalamocortical connections were compared between the two groups. Probabilistic tractography analyses showed that fractional anisotropy of thalamocortical pathways in patients with epilepsy decreased significantly, and the radial diffusivity of the left thalamus pathways with homolateral motor and parietal-occipital cortical regions in the drug-resistant epilepsy group increased significantly. In addition to the right thalamus pathway and prefrontal cortical region, fractional anisotropy of all other pathways was inversely correlated with disease duration. The results provide evidence indicating widespread bilateral abnormalities in the thalamocortical pathways in epilepsy patients and imply that the degree of abnormality in the pathway increases with the disease duration.

- Abstract
Labor division of the two brain hemispheres refers to the dominant processing of input information on one side of the brain. At an early stage, or a preattentive stage, the right brain hemisphere is shown to dominate the auditory processing of tones, including lexical tones. However, little is known about the influence of brain damage on the labor division of the brain hemispheres for the auditory processing of linguistic tones. Here, we demonstrate swapped dominance of brain hemispheres at the preattentive stage of auditory processing of Chinese lexical tones after a stroke in the right temporal lobe (RTL). In this study, we frequently presented lexical tones to a group of patients with a stroke in the RTL and infrequently varied the tones to create an auditory contrast. The contrast evoked a mismatch negativity response, which indexes auditory processing at the preattentive stage. In the participants with a stroke in the RTL, the mismatch negativity response was lateralized to the left side, in contrast to the right lateralization pattern in the control participants. The swapped dominance of brain hemispheres indicates that the RTL is a core area for early-stage auditory tonal processing. Our study indicates the necessity of rehabilitating tonal processing functions for tonal language speakers who suffer an RTL injury., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Wei, Liang, Guo, Wang, Qi, Ali, Wu, Qian, Wang, Qiu, Li, Fu and Chen.)

- Abstract
Seizures are a common symptom of craniocerebral diseases, and epilepsy is one of the comorbidities of craniocerebral diseases. However, how to rationally use anti-seizure medications (ASMs) in the perioperative period of craniocerebral surgery to control or avoid seizures and reduce their associated harm is a problem. The China Association Against Epilepsy (CAAE) united with the Trauma Group of the Chinese Neurosurgery Society, Glioma Professional Committee of the Chinese Anti-Cancer Association, Neuro-Oncology Branch of the Chinese Neuroscience Society, and Neurotraumatic Group of Chinese Trauma Society, and selected experts for consultancy regarding outcomes from evidence-based medicine in domestic and foreign literature. These experts referred to the existing research evidence, drug characteristics, Chinese FDA-approved indications, and expert experience, and finished the current guideline on the application of ASMs during the perioperative period of craniocerebral surgery, aiming to guide relevant clinical practice. This guideline consists of six sections: application scope of guideline, concepts of craniocerebral surgery-related seizures and epilepsy, postoperative application of ASMs in patients without seizures before surgery, application of ASMs in patients with seizures associated with lesions before surgery, emergency treatment of postoperative seizures, and 16 recommendations., Competing Interests: Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s), 2022.)

- Abstract
Circular RNAs (circRNAs) are usually enriched in neural tissues, yet about 80% circRNAs have lower expression in gliomas relative to normal brains, highlighting the importance of circRNAs as tumor suppressors. However, the clinical impact as well as the pathways regulated by the tumor-suppressive circRNAs remain largely unknown in glioblastoma (GBM). Through bioinformatic analysis followed by experimental validation, we found that hsa_circ_0114014 (circLRRC7) was dramatically down-regulated in GBM when compared with normal brain tissues ( p < 0.0001). GBM patients with a lower circLRRC7 expression had poorer progression-free survival (PFS, p < 0.05) and overall survival (OS, p < 0.05). Analyses of the predicted target miRNAs of circLRRC7 in CSCD and CRI databases, in combination with the miRNA expression data in GBMs and normal brains from GSE database, revealed miR-1281 as a potential downstream target of circLRRC7. Subsequently, the target genes of hsa-mir-1281 were predicted by TargetScan, miRDB and miRNATAR databases. Intersection analysis and correlation test indicated that PDXP was a potential target of miR-1281. In summary, circLRRC7 may be a tumor suppressor that associated with miR-1281 and PDXP expression in GBM, which may provide novel therapeutic targets for GBM treatment., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Kong, Xu, Wang, Zeng, Li, Lin, Zhou, Fu and Wu.)

- Abstract
Background: Refractory epilepsy is a common and troublesome neurosurgical disease. This study is designed to compare seizure control and degrees in intellectual outcome in children with refractory epilepsy after surgical treatment., Methods: 20 children with refractory epilepsy were treated with tailored epilepsy surgery or vagus nerve stimulation (VNS). We used the Engel Epilepsy Surgery Outcome Scale to evaluate seizure control and the Wechsler Intelligence Scale for Children, fourth edition (WISC-IV), to test the children's intellectual outcomes 7-day preoperative and 3-, 6-, and 12-month postoperative., Results: In total, 14 cases were seizure free (Engel I) and 2 cases to have suffered few attacks since surgery (Engel II). In two cases, the frequency of seizures decreased by >90% (Engel III). In the remaining two cases, the effects of surgery on seizure control were not obvious (Engel IV). All children completed the WISC-IV test. On average, postoperative intelligence quotient (IQ) increased by 6.35 points 12-month postsurgery compared with the results of the preoperative tests ( P < 0.01). Second, intellectual outcomes after surgery in the Engel I and II groups increased by >3.88 points compared with in the Engel III and IV groups ( P < 0.05). Finally, there were no fatal complications over the long-term follow-up except for intracranial infection of two cases; postoperative subcutaneous hematoma occurred in one case and hoarseness in one case., Conclusion: Individualized epilepsy surgery is safe and effective for children with refractory epilepsy. It can control or reduce the frequency of postoperative attacks as well as improve postoperative intellectual outcomes to different degrees., Competing Interests: There are no conflicts of interest.

- Abstract
BACKGROUND Sun's procedure is a surgical technique widely used in type A aortic dissection. The purpose of this study was to analyze clinical outcomes and morphologic changes in true and false lumen by computed tomography (CT) angiography after Sun's procedure. MATERIAL AND METHODS We retrospectively reviewed 51 patients who underwent Sun's procedure for acute Stanford type A aortic dissection extending down to iliac bifurcation between January 2013 and December 2014. The images of preoperative, one-month, three-month, and six-month follow-up were analyzed by CT angiography to measure the area and diameter of true and false lumen. RESULTS Four patients died before surgical intervention and postoperative deaths occurred in five patients (in-hospital mortality rate 10.6%). Only 42 patients (36 male, 6 female; mean age, 45.9±9.8 years; range, 24-65 years) with acute type A aortic dissection were involved in our study. Thirty-five patients (83.3%) suffered from chest or abdominal pain and only one patient (2.4%) was asymptomatic. Thirty-seven patients (88.1%) had hypertension as the most common comorbidity. In the ascending aorta, false lumen was eliminated and the change of true lumen was not significant (p>0.05). In the descending aorta, complete and partial thrombosis of false lumen were observed in eight patients (19.0%) and 33 patients (78.6%) by one-month follow-up CT scan, respectively. After the six-month follow-up, the rate of complete thrombosis increased to 36.1% and partial thrombosis decreased to 61.9%. The area and maximal diameter of true lumen were increased significantly (p<0.05), whereas significant decreases were found in the area and maximal diameter of false lumen (p<0.05). In the abdominal aorta, thrombosis was found in 52.4% patients at one-month follow-up CT. Furthermore, there were no significant changes in both true and false lumen within three months (p>0.05). Nevertheless, the false luminal area and maximal diameter decreased significantly (p<0.05) after six months, while these changes of true lumen were not significant (p>0.05). CONCLUSIONS After Sun's procedure, aortic remodeling was a continuous process and occurred in a predictable model, and the extent of aortic remodeling varied at different levels. Remodeling in descending thoracic aorta was earlier than it was in abdominal aorta.

- Abstract
Embolisation of irregular and complicated aneurysms is a great challenge for neuroradiologists. To overcome possible complications of endovascular treatment of these type of aneurysms, methods such as intracranial stents, balloon remodelling, and the double microcatheter technique have been developed. The aim of the study was to report our preliminary experience with endovascular treatment of irregular and complicated intracranial aneurysm with coils using double microcatheter technique, and evaluation of its feasibility and clinical advantages. In this retrospective study, 37 cases diagnosed with irregular and complicated intracranial aneurysms and treated using double microcatheter method from July, 2013 to May, 2015, were followed up for six months after discharge. All the aneurysms were successfully embolized using the double microcatheter technique. Immediate post-embolization angiography showed no residual contrast filling in 35 cases, and residual filling in 2 cases. At discharge, according to the modified Rankin Scale score, all the patients recovered without any complications or death. A follow-up of 24 cases with digital subtraction angiography for 6 months revealed no recanalization. In conclusion, the double microcatheter technique for irregular intracranial aneurysms is effective and simple with few complications.

- Abstract
Background: Cranioplasty is considered as a routine procedure in everyday neurosurgical practice for the patient with cranial defect, however, there is no established consensus on optimal surgical timing., Objective: To compare the effect of early cranioplasty (1-3 months after DC) and late cranioplasty (3-6 months after DC) on the complications and recovery of neurological function in the management of patients who received decompressive craniotomy., Methods: In this paper, the authors report a systematic review and meta-analysis of operative time, complications and neurological function outcomes on different timing of cranioplasty. Randomized or non-randomized controlled trials of early cranioplasty and late cranioplasty surgery were considered for inclusion., Results: Nine published reports of eligible studies involving 1209 participants meet the inclusion criteria. Compared with late cranioplasty, early cranioplasty had no significant difference in overall complications [RR=1.14, 95%CI (0.83, 1.55), p>0.05], infection rates [RR=0.87, 95%CI (0.47, 1.61), p>0.05], intracranial hematoma [RR=1.09, 95%CI (0.53, 2.25), p>0.05]; subdural fluid collection [RR=0.47, 95%CI (0.15, 1.41), p>0.05]. However, early CP significantly reduced the duration of cranioplasty [mean difference=-13.46, 95%CI (-21.26, 5.67), p<0.05]. The postoperative hydrocephalus rates were significant higher in the early cranioplasty group [RR=2.67, 95%CI (1.24, 5.73), p<0.05]., Conclusion: Early CP can only reduce the duration of operation, but cannot reduce the complications of patients and even increase the risk of hydrocephalus. More evidence from advanced multi-center studies is needed to provide illumination for the timing selection of CP surgery., (Copyright © 2015 Elsevier B.V. All rights reserved.)

- Abstract
Objective: To discuss the alterations of brain network efficiency in patients with post-concussion syndrome., Methods: A total of 23 patients from Anhui Provincial Hospital in the period from 2013/6 to 2014/3 who have had the concussion for 3 months were enrolled and 23 volunteers paired in sex, age and education were also enrolled as healthy controls. Comparisons of selective attention of both groups were conducted using Stroop Word-Color Test. The data of resting-state functional magnetic resonance imaging (fMRI) in both groups were collected and the data were dealt with Network Construction which is a part of GRETNA software to obtain the Matrix of brain network. Network analysis was used to obtain Global and Nodal efficiency, then independent t-test was used for statistical analyses of the value of Global and Nodal efficiency., Results: The difference in Global efficiency of two groups in every threshold value had no statistical significance. Compared with healthy controls, the Nodal efficiencies in patients with post-concussion syndrome were significantly different in the brain regions as below: left orbital middle frontal gyrus, left posterior cingulate, left lingual, left thalamus, left superior temporal gyrus, right anterior cingulate, right posterior cingulate, right supramarginalgyrus., Conclusions: Compared with healthy controls, there is no significant changes of Globe efficiency in patients with post-concussion syndrome, and the brain function deficits in these patients may be caused by changes of Nodal efficiency in their brain network.

- Abstract
Objective: To explore the functions of amygdala functional connectivity in the pathogenesis of refractory epilepsy with resting-state functional magnetic resonance imaging (RS-fMRI)., Methods: A total of 19 patients with refractory epilepsy were recruited from August 2013 to June 2014. And 19 healthy persons were selected as the controls.No obvious epileptogenic lesions of intracranial structures were found on multi-modal neuroimaging.Ictal and interictal epileptic activities on long-term video electroencephalogram (EEG) showed spine spread spike and wave in bilateral cerebral hemispheres. All fMRI data were preprocessed after RS-fMRI scanning. Then left and right amygdalas were selected as regions of interest (ROIs) for calculating the linear correlation between amygdala and whole brain. As relative to the control group, the changes of brain areas in functional connectivity were examined for the intractable epilepsy group., Results: Compared with the controls, left amygdala in refractory epilepsy group showed increased functional connectivity with bilateral fusiform gyrus, bilateral calcarine gyrus and right lingual, on the contrary decreased functional connectivity with bilateral cuneus, bilateral precuneus, bilateral caudatas and left thalamus.However, right amygdala demonstrated increased functional connectivity with bilateral calcarine gyrus and bilateral linguals, but decreased functional connectivity with bilateral caudatas and left putamen (P < 0.05)., Conclusion: Altered functional connectivity of amygdala reflects its dysfunction in refractory epilepsy patients. It suggested that amygdala is an important component of "epileptic network" participating in the occurrence and development of refractory epilepsy.
