简介:陆地使用和陆地盖子变化(LULCC)强烈由联合生物化学、生物物理的过程影响地区性、全球的气候。然而,生物物理的过程经常被忽略,它可以抵消biogeochemical效果,因此到地址气候变化的措施不能到达目标。因此,LULCC的生物物理的影响为观察气候以后在过去和潜在的情形改变的理解是批评的。因此,鉴别气候上的大规模LULCC的机制和效果通过改变内在的表面变化是必要的,并且这样精力平衡。在必须被探讨包括的全球气候上理解人的活动的影响上的关键科学问题:(1)在中国和比较国家的LULCC的空间、时间的变化的基本科学事实是什么?(2)怎么理解联合在LULCC上然后到预报未来情形驾驶人的活动和气候变化的机制?(3)LULCC的科学机制是什么,在陆地表面,然后气候的生物物理的过程上影响吗?(4)怎么估计到气候的LULCC的贡献由影响土地的生物物理的过程变化出现?由国际比较,在本地、地区性、全球的规模的气候变化上的LULCC的影响被揭示并且评估。它能为全球变化提供理论基础,并且有大意义减轻并且适应全球气候变化。

简介:AbstractBackground:Ophthalmic ambulatory surgery is preferred to be performed under general anesthesia either by total intravenous anesthesia (TIVA) or by inhalational anesthesia to increase the patient comfort. However, anesthesia-controlled time (ACT) can cause increased non-operative operating room (OR) time which may adversely affect the ORs efficiency. This study was aimed to compare the ACT of desflurane with that of propofol-remifentanil in strabismus ambulatory surgery.Methods:From November 2016 to December 2017, a total of 200 strabismus patients (aged 18-60 years old, and scheduled for elective ambulatory surgery at Zhongshan Ophthalmic Center) were randomly assigned to receive either propofol-based TIVA (group TIVA) or desflurane anesthesia (group DES) for maintenance of anesthesia. The primary outcome was the extubation time. Secondary outcomes included surgical time, anesthetic time, OR exit time, and Phase I and II recovery time. The intraoperative incidences of hypotension, bradycardia and oculocardiac reflex (OCR), and the incidences of any post-operative complications were recorded. Mann-Whitney U test and Chi-square or Fisher exact tests were used to compare the two groups.Results:We found that the extubation time (5.5 [3.9-7.0] vs. 9.7 [8.5-11.4] min, P < 0.001) and the incidence of prolonged time to extubation (0 vs. 6%, P = 0.029) in the DES group were significantly decreased compared with those in the TIVA group. The patients in the DES group displayed shorter OR exit time as compared with that in the TIVA group (7.3 [5.5-8.7] vs. 10.8 [9.3-12.3] min, P < 0.001). The patients using desflurane exhibited more stable hemodynamics during surgery than the patients using propofol-based TIVA, as demonstrated by lower incidences of hypotension (1% vs. 22%, P < 0.001), bradycardia (2% vs. 13%, P = 0.002), and OCR (17% vs. 44%, P < 0.001).Conclusion:DES enhanced the ophthalmic OR efficiency by reducing the extubation time and OR exit time, and provided more stable hemodynamics intra-operatively than TIVA in patients undergoing strabismus ambulatory surgery.Trial registration:ClinicalTrials.gov, No. NCT02922660; https://clinicaltrials.gov/ct2/show/NCT02922660?id=NCT02922660&draw=2&rank=1
简介:摘要ObjectivesTo investigate whether botulinum toxin type A (BTX-A) injection is more effective than radial extracorporeal shock wave therapy in reducing plantar flexor muscle spasticity in subjects with cerebral palsy.MethodsA total of 68 subjects with cerebral palsy were randomly allocated to BTX-A injection (Group 1) or radial extracorporeal shock wave therapy (Group 2) (first experiment; E1). Outcome was evaluated using the Tardieu V1 and V3 stretches, at 3 weeks, 2 months (M2) and M3 after baseline. At M6 subjects in Group 1 received radial extracorporeal shock wave therapy and subjects in Group 2 received BTX-A injection (second experiment; E2); outcome was evaluated as in E1. Treatment success was defined as improvement in foot dorsiflexion ≥10° when performing the V3 stretch at M2 in both experiments.ResultsIn both experiments mean V1 and V3 significantly improved over time. In E1 both treatments resulted in similar treatment success. In E2 fewer subjects treated with BTX-A injection reached the criteria of treatment success than did subjects treated with radial extracorporeal shock wave therapy, which was due to a carry-over effect from E1. No significant complications were observed.ConclusionBTX-A injection is not superior to radial extracorporeal shock wave therapy in the treatment of plantar flexor muscle spasticity in subjects with cerebral palsy.
