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 a 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 ***-three demographic and disease-related factors associated with acupuncture response in 183 participants were analyzed by multivariable logistic *** One hundred and nineteen(65.0%)participants were classified as *** 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 *** assignment was associated with non-response: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 *** 3 factors require independent validation as predictors of acupuncture effectiveness in CTTH.

土地利用/覆被变化会增加区域碳储量或引发碳损耗,进而影响全球气候.研究湾区土地利用与碳储量变化的影响机制,对区域生态系统保护及社会经济可持续发展具有重要意义.基于InVEST模型和PLUS模型,分析了粤港澳大湾区土地利用与碳储量的动态变化特征及影响机制,进一步模拟预测了2030年3种发展情景(自然趋势情景、建设用地优先情景和生态优先情景)下土地利用类型变化对碳储量的影响.结果表明:(1)2000~2020年粤港澳大湾区的耕地(减少5.38%)和建设用地(增加8.68%)变化最显著,其余用地类型的变化较小.林地作为大湾区的主要用地类型,同样也是重要的碳库,空间上集中分布于东、北、西三面的台地和丘陵地区,碳储存低值区集中于中部平原,以建设用地为主.(2)受不同用地类型相互转化的影响,粤港澳大湾区的碳损失了20.12×10^(6) Mg.耕地和林地面积的减少以及建设用地面积的增加是碳损耗的主要原因.(3)模拟研究发现生态保护措施将有效提高区域碳储量.具体来说,当耕地、林地和草地向建设用地的转化减少20%,湿地和水体向建设用地的转化减少30%时(生态优先情景),区域碳储量可增加2.58×10^(6) Mg.研究结果可以为土地利用和城市发展规划的制定提供理论依据,促进粤港澳大湾区“碳达峰碳中和”目标的实现.

BACKGROUND Cardioneuroablation(CNA)has shown encouraging results in patients with vasovagal syncope(VVS).However,data on different subtypes was *** This observational study retrospectively enrolled 141 patients[mean age:40±18 years,51 males(36.2%)]with the diagnosis of *** characteristics among different types of VVS and the outcomes after CNA were *** After a mean follow-up of 4.3±1.5 years,41 patients(29.1%)experienced syncope/pre-syncope events after ***/pre-syncope recurrence significantly differed in each subtype(P=0.04).The cardioinhibitory type of VVS had the lowest recurrence rate after the procedure(n=6,16.7%),followed by mixed(n=26,30.6%)and vasodepressive(n=9,45.0%).Additionally,a significant difference was observed in the analyses of the Kaplan-Meier survival curve(P=0.02).Syncope/pre-syncope burden was significantly reduced after CNA in the vasodepressive type(P<0.01).Vasodepressive types with recurrent syncope/pre-syncope after CNA have a lower baseline deceleration capacity(DC)level than those without(7.4±1.0 ms vs.9.0±1.6 ms,P=0.01).Patients with DC<8.4 ms had an 8.1(HR=8.1,95%CI:2.2-30.0,P=0.02)times risk of syncope/pre-syncope recurrence after CNA compared to patients with DC≥8.4 ms,and this association still existed after adjusting for age and sex(HR=8.1,95%CI:2.2-30.1,P=0.02).CONCLUSIONS Different subtypes exhibit different event-free *** vasodepressive type exhibited the lowest event-free rate,but those patients with DC≥8.4 ms might benefit from CNA.
