Background and purpose: Vascular and tension-type headache is most commonly encountered, and SI17 therapy has been tested to treat headache with good results. The efficacy of SI17 therapy for vascular and tension-type headache was compared and the effect of SI17 therapy on pancreatic polypeptide (PP) was studied. Materials and methods: 29 cases of vascular headache (20 cases in acute attack during the trial) and 27 cases of tension-type headache (19 cases in acute attack) were enrolled in the study. Plasma PP level before and 4th day after treatment was measured by radioimmunoassay. Results: SI17 therapy is better for the treatment of vascular headache. Vascular headache with higher PP level and tension-type headache with normal PP level had good therapeutic results. Conclusion: The clinical efficacy is better for vascular headache with the increase of vagus tension and for tension-type headache with normal vagus tension.   展开更多

Objective: To explore the demographic and disease-related factors associated with acupuncture response in patients with chronic tension-type headache(CTTH). Methods: Using data from the randomized clinical trial(218 cases) consisting of 4 weeks of baseline assessment, 8 weeks of treatment, and 24 weeks of follow-up, participants were regrouped into responders(at least a 50% reduction in monthly headache days at week 16 compared with baseline) and non-responders. Twenty-three demographic and disease-related factors associated with acupuncture response in 183 participants were analyzed by multivariable logistic regression. Results: One hundred and nineteen(65.0%) participants were classified as responders. Four factors were significantly independently associated with acupuncture response, including treatment assignment, headache intensity at baseline, and 2 domains [general health(GH) and social functioning(SF)] from the 36-Item Short Form Health Survey quality of life questionnaire. Treatment assignment was associated with nonresponse: participants receiving true acupuncture were 3-time more likely to achieve a CTTH response than those receiving superficial acupuncture [odds ratio(OR) 0.322, 95% confidence interval(CI) 0.162 to 0.625, P=0.001]. Compared with patients with mild-intensity headache, patients with moderate-intensity headache were twice as likely to respond to acupuncture(OR 2.001, 95% CI 1.020 to 4.011, P=0.046). The likelihood of non-response increased by 4.5% with each unit increase in the GH grade(OR 0.955, 95% CI 0.917 to 0.993, P=0.024) while decreased by 3.8% with each unit increase in the SF grade(OR 1.038, 95% CI 1.009 to 1.069, P=0.011). Conclusions: Greater headache intensity, lower GH score, and higher SF score were associated with better acupuncture responses in CTTH patients. These 3 factors require independent validation as predictors of acupuncture effectiveness in CTTH. 展开更多

Methods: MIR was studied in 21 sex matched to the study cohort. Median age of patients was reflex (MIR) and its eventual changes in patients with episodic patients with episodic TTH and 30 healthy subjects, with age and 17.0 years (ranged 16-49 years), median duration of disease 12 months (1-5 years), and median frequency of headache 7.5 d per month. Results: The second period of suppression ($2) of MIR was reduced in intensity and duration in 10% of controls and 66.7% (confidence interval (CI) 45.3%-85%; P〈0.05) of patients with episodic TTH (X2=74.9; P〈0.001). In 3 (14.3%) of patients with episodic TTH, S2 was completely absent. No significant correlation between the duration of disease and headache frequency was found. Conclusion: Our results confirm the link between episodic TTH and reduction or absence of S2. Teenage patients with episodic TTH may exhibit marked pathological changes in S2 in contrast to older individuals. 展开更多

Objective:To investigate the clinical efficacy and safety of miniscalpel-needle(MSN)treatment for tension-type headache(TTH).Method:Seven medical databases were searched to identify randomized controlled trials(RCTs)evaluating the effect and safety of MSN treatment.All articles published up to November 15,2018 were retrieved.A meta-analysis was conducted for the included studies,and the risk of bias was assessed.Primary outcomes were visual analogue scale(VAS)or numeric rating scale(NRS)score.Secondary outcomes were clinical effective rates including total effective rate(TER),markedly effective rate(MER),and totally cured rate(TCR)determined by improvement in clinical symptoms or VAS scores,the frequency of adverse events(AEs)that occurred during the study,and participant quality of life(QOL).Results:Seven RCTs involving 724 participants were included.MSN treatment showed significantly higher MER and TCR[relative risk(RR)1.27,95%confidence interval(Cl)1.01 to 1.61;RR 1.31,95%Cl 1.09 to 1.57,respectively],but not TER(RR 1.03,95%Cl 0.96 to 1.10)compared to acupuncture.MSN treatment plus conventional treatment showed significant lower VAS and higher TER,MER,and TCR(mean difference-3.54,95%Cl-3.80 to-3.28;RR 1.14,95%Cl 1.06 to 1.23;RR 2.31,95%Cl 1.50 to 3.58;RR 3.01,95%Cl 2.25 to 4.02,respectively)compared to conventional treatment.Conclusions:According to current evidence,MSN treatment as a monotherapy or as an adjunctive treatment to other existing treatments might have benefits on treating TTH.However,since the number and the sample size of studies included were both small and the methodological quality was poor,the findings of this review should be interpreted with great caution,and our confidence in the results is low.A high quality RCT using objective outcomes should be performed on this topic. 展开更多

Objective:To observe the clinical efficacy of acupuncture plus auricular point sticking for tension-type headache(TTH).Methods:A total of 90 TTH patients were divided into an acupuncture group,an auricular point sticking group and an observation group by random number table method,with 30 cases in each group.Patients in the observation group received acupuncture plus auricular point sticking for treatment,while those in the acupuncture group only received acupuncture and those in the auricular point sticking group only received auricular point sticking for treatment.The headache attack frequency and the scores of visual analog scale(VAS),self-rating anxiety scale(SAS)and self-rating depression scale(SDS)were observed before treatment,after treatment and 3 months after treatment.The clinical efficacy was evaluated at the follow-up of 3 months after treatment.Results:At follow-up,there were significant differences in clinical efficacy among the three groups(P<0.01 or P<0.05),and the clinical efficacy ranking from high to low was the observation group,the acupuncture group and the auricular point sticking group.After treatment and at follow-up,the VAS score,headache attack frequency,SAS and SDS scores in the three groups were significantly lower than those before treatment(all P<0.01).The above four results in the observation group were lower than those in the acupuncture group and the auricular point sticking group at the same time point(all P<0.01);VAS score in the acupuncture group was lower than that in the auricular point sticking group(both P<0.05).At follow-up,the headache frequency in the acupuncture group was lower than that in the auricular point sticking group(P<0.05).Conclusion:Either using acupuncture and auricular point sticking together or separately can reduce the headache degree of TTH patients,reduce the number of headache attacks,and relieve anxiety and depression.The efficacy of acupuncture plus auricular point sticking is most significant. 展开更多

BACKGROUND Restless legs syndrome(RLS)is characterized by an urge to move with an unpleasant sensation in the lower limbs.RLS typically affects the legs.However,it can also affect several other body regions,such as the arms,abdomen,face,neck,head,and genital area.There are only a few reports of the RLS variant affecting the head.AIM To assess the epidemiological,clinical,and other aspects of the RLS variant affecting the head.METHODS We conducted a retrospective study of 17 adult patients(>18 years)who met the RLS criteria and simultaneously experienced RLS-like symptoms in the head.RESULTS The median age at which symptoms appeared was 41.6 years.Males and females were equally affected(1.1:1).All 17 patients had uncomfortable sensations in the lower legs.Insomnia or disturbed sleep was the most common comorbidity(n=16,88.2%).However,headache was the most common presenting or primary symptom(n=10,70.5%).Dizziness or an abnormal sensation in the head was the second most common presenting symptom(5 patients,29.4%).Other presenting features were leg pain,backache,and generalized body pain.All patients responded favorably to dopaminergic medications.CONCLUSION If RLS-related unpleasant sensations and pain are felt in the head,they may be misinterpreted as headache,dizziness,or psychosomatic symptoms.RLS and headaches in a subset of patients may be two phenotypic manifestations of the same disorder. 展开更多

P型橡胶卡箍是航空发动机外部管路系统中连接管路与支架、机匣之间的重要连接件,其主要的失效形式为机体振动和管内高压液体脉动共同作用下的疲劳断裂。卡箍的疲劳性能极大地制约了管路系统的性能,因此对于卡箍的疲劳性能研究具有重要意义。本文首先设计并进行了卡箍的拉压疲劳试验,得到了不同加载位移下的疲劳寿命。后续的断口分析表明卡箍疲劳破坏呈现出两种不同的形式:一是卡箍的金属箍带发生由外侧向内侧扩展的疲劳断裂,二是卡箍的橡胶垫圈严重的磨损现象。其次,结合卡箍疲劳试验的加载过程,建立了对应的有限元模型,并通过与贴片位置的应变对比验证了构建模型的预测精度。针对卡箍箍带疲劳断裂的失效形式,通过卡箍箍带所采用的不锈钢材料的疲劳试验结果,建立了卡箍的SWT(Smith-Watson-Topper)、FS(Fatemi-Socie)以及WB(Wang-Brown)临界平面疲劳寿命模型。最后,结合有限元分析得到的最大应力应变以及卡箍拉压疲劳试验得到的疲劳寿命结果,验证了提出的寿命模型均处于3倍分散带内,对于卡箍的疲劳寿命具有良好的估计精度。 展开更多
