Objective To evaluate the effects of cold provoca tion on optic dise blood flow and retinal light sensitivity of primary open-angle glaucoma (POAG) patients,and explore the relationship between the changes of optic disc blood flow and retin al light sensitivity. Methods A total 33 POAG patients (33 eyes)and 13 normal controls (13 eyes) were tested by usin g th e Heidelberg retinal flowmetry (HRF) and Topcon automatic perimeter,and the optic disc blood flow and retinal light sensitivity of POAG patients and normal cont rols were measured at normal conditions and after cold provocation. Results The mean optic disc blood flow,volume and the mean retinal light sensitivity of POAG patients decreased significantly (Plt;0.05) after cold provocation.There was a linear and significant relationsh ip between the decrease of mean optic disc blood flow and mean retinal light sen sitivity of POAG patients (r=0.615,P＜0.001). The optic disc blood flow of POAG patients with a history of migraine were more likely to r educe in response to cold provocation and reduced much more than those without such history (Plt;0.05). Conclusion Cold provocation can significantly reduce both the optic disc blood flow and retinal light sensitivity in POAG patients.A close correlation was fo und between the amount of mean optic disc blood flow decrease and the volume of mean retinal light sensitivity decline.

Migraine is the most common primary headache clinically, with high disability rate and heavy burden. Functional MRI (fMRI) plays a significant role in the study of migraine. This article reviews the main advances of migraine without aura (MwoA) based on resting-state fMRI in recent years, including the exploration of the mechanism of fMRI in the occurrence and development of MwoA in terms of regional functional activities and functional network connections, as well as the research progress of the potential clinical application of fMRI in aiding diagnosis and assessing treatment effect for MwoA. At last, this article summarizes the current distresses and prospects of fMRI research on MwoA.
Objective To improve care and outcomes for all migraine suffers, the USHC created these evidence-based guidelines for migraine headache. Methods Firstly, 5 relative Technical reviews were done according to the Methods used in the AHCPR Technical Reviews. Secondly, based on the results of the 5 technical reviews, the 4 treatment guidelines were developed in direction of the USHC’S Methods used in developing clinical guidelines. Results Evidence supporting the acute treatment and preventive treatment were exclusively Class 1 studies, evidence supporting the diagnostic testing were either Class 2 or Class 3 studies , only very few expert judgment was given on some compelling issues without evidence. The recommendations they supporting were high-qualified, middle-qualified, and poor-qualified respectively. Conclusion This Evidence-Based Guidelines is one of the first and most extensive cooperative projects available for creating guidelines. The guideline was developed with systematical and scientific methods and stroven to base all of its recommendations on evidence.
ObjectivesTo systematically review the efficacy of acupuncture for improving migraine symptoms and cerebral blood flow velocity.MethodsCBM, CNKI, VIP, WanFang Data, PubMed, EMbase and The Cochrane Library databases were electronically searched to collect randomized controlled trials (RCTs) on acupuncture for improving migraine symptoms and cerebral blood flow velocity from inception to September, 2017. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 17 RCTs involving 2 226 patients were included. The results of meta-analysis showed that, acupuncture could effectively reduce the frequency of migraine compared with placebo acupuncture (SMD=−0.97, 95%CI −1.60 to −0.34, P=0.002) and medicine group (SMD=−1.29, 95%CI −1.85 to −0.73, P<0.000 01). Acupuncture could shorten duration of headache compared with placebo acupuncture (SMD=−0.73, 95%CI −1.25 to −0.21, P=0.006) and medicine group (SMD=−0.88, 95%CI −1.32 to −0.45, P<0.000 1). Compared with placebo acupuncture, acupuncture could relieve headache intensity (SMD=−0.67, 95%CI −1.15 to −0.19, P=0.006). The acupuncture group was superior to the placebo acupuncture group (SMD=−10.99, 95%CI −16.62 to −5.36, P=0.000 1) and medicine group (SMD=−0.63, 95%CI −0.87 to −0.40, P<0.000 01) in improving the cerebral blood flow velocity.ConclusionsCurrent evidence shows that acupuncture can effectively reduce frequency of migraine, shorten duration of migraine, relieve intensity of migraine and improve cerebral blood flow velocity. Due to limited quality of the included studies, more high quality studies are required to verify above conclusion.
ObjectiveTo investigate the risk factors of perioperative anaesthesia management in postoperative headache induced by thyroidectomy. MethodsA 1:1 age and operation time matched case-control design study was performed. General anesthesia patients for elective thyroidectomy with postoperative headache (case group, VAS score >4) and without postoperative headache (control group, VAS score ≤4) were recruited. Univariate and multivariate analyses were performed to analyze the risk factors of postoperative headache after 24 and 48 hours of operation by using SPSS 18.0 software. ResultsA total of 134 patients were included; of which, 67 were in the case group and the other 67 were in the control group. The results of univariate analysis showed that female and administration of flurbiprofen axetil might be the risk factors of postoperative headache. The further multivariate analysis showed that administration of flurbiprofen axetil was significantly associated with decreased postoperative headache (OR=0.387, 95%CI 0.185 to 0.811). ConclusionPerioperative anesthesia management has a certain influence on postoperative headache induced by thyroidectomy. The use of flurbiprofen axetil during operation could reduce the incidence rate of postoperative headache.
