While, the parameters of cardiac function LVEF and ventricular systolic synchrony LVPS were measured by 99m Tc gated cardiac blood pool image on the first and the fourth weekend. Results (1) The peak CK MB was significantly lower in group A than that in group B( P <0.01 ). (2) Myocardial infarction area (MIA) was decreased and radioactivity counts in MIA was significantly increased in group A and B on the 4th weekend compared with that on the first weekend ( P <0.01 ), but there were no significant difference between group A and group B. (3) LVEF, LVPS were no significant difference between group A and group B.Conclusions (1)pPCI in acute myocardial infartion can limit infarct area, maintain ventricular systolic synchrony and improve ventricular function; (2) but, in those hospitals that there were no any condition for PCI, they should transfer the patients to central hospital for PCI after thrombolysis at the first time. It is beneficial to improve myocardial viability and ventricular systolic synchrony of AMI patients in short time.展开更多

In this study, the blends of hydrophilic polymers polyvinyl pyrrolidone(PVP) and polyvinyl alcohol(PVA) were studied to find an optimal polymer matrix to host carriers in facilitated transport membranes for enhanced CO2 separation. It is found out that the optimized blend is 50/50 PVA/PVP by weight, which shows a significant increase in the water uptake(from 63 to 84%) at equilibrium state compared to the neat PVA. Polyethyleneimine(PEI) was employed to provide sample carriers to evaluate the synergistic effect of PVA and PVP on the CO2 separation performance. A thin film composite(TFC) membrane of the optimized blend(50/50 PVA/PVP with 50 wt% PEI) was fabricated on polysulfone(PSf) porous support. The fabrication of the TFC membranes is simple and low cost, and CO2 permeance of the optimized blend membrane is nearly doubled with the CO2/N2 selectivity remained unchanged, showing great potential for industrial applications of the resulted membranes.展开更多

I...C3 plant Reaumuria soongorica and C4 plant Salsola passerina are super xerophytes and coexist in a mixed community in either isolated or associated growth, and interspecific facilitation occurs in associated growth. In the present study, the root traits including root distribution, root length（RL）, root surface area（RSA）, root weight（RW） and specific root length（SRL） of both species in two growth forms were investigated to clarify their response to facilitation in associated growth. Six isolated plants of each species, as well as six associated plants similar in size and development were selected during the plant growing season, and their roots were excavated at 0–10, 10–20, 20–30, 30–40 and 40–50 cm soil depths at the end of the growing season. All the roots of each plant were separated into the two categories of fine roots（2 mm diameter） and coarse roots（≥2 mm diameter）. Root traits such as RL and RSA in the fine and coarse roots were obtained by the root analyzing system WinRHIZO. Most of the coarse roots in R. soongorica and S. passerina were distributed in the top 10 cm of the soil in both growth forms, whereas the fine roots of the two plant species were found mainly in the 10–20 and 20–30 cm soil depths in isolated growth, respectively. However, the fine roots of both species were mostly overlapped in 10–20 cm soil depth in associated growth. The root/canopy ratios of both species reduced, whereas the ratios of their fine roots to coarse roots in RL increased, and both species had an increased SRL in the fine roots in associated growth. In addition, there was the increase in RL of fine roots and content of root N for S. passerina in associated growth. Taken together, the root growth of S. passerina was facilitated for water and nutrient exploration under the interaction of the overlapped roots in both species in associated growth, and higher SRL allowed both species to more effectively adapt to the infertile soil in the desert ecosystem.展开更多

文摘The well-facilitated farmland projects(WFFPs)involve the typical sustainable intensification of farmland use and play a key role in raising food production in China.However,whether such WFFPs can enhance the nitrogen(N)use efficiency and reduce environmental impacts is still unclear.Here,we examined the data from 502 valid questionnaires collected from WFFPs in the major grain-producing area,the Huang-Huai-Hai Region(HHHR)in China,with 429 samples for wheat,328 for maize,and 122 for rice.We identified gaps in N use efficiency(NUE)and N losses from the production of the three crops between the sampled WFFPs and counties based on the statistical data.The results showed that compared to the county-level(wheat,39.1%;maize,33.8%;rice,35.1%),the NUEs for wheat(55.2%),maize(52.1%),and rice(50.2%)in the WFFPs were significantly improved(P<0.05).In addition,the intensities of ammonia(NH3)volatilization(9.9-12.2 kg N ha–1),N leaching(6.5-16.9 kg N ha–1),and nitrous oxide(N2O)emissions(1.2-1.6 kg N ha–1)from crop production in the sampled WFFPs were significantly lower than the county averages(P<0.05).Simulations showed that if the N rates are reduced by 10.0,15.0,and 20.0%for the counties,the NUEs of wheat,maize,and rice in the HHHR will increase by 2.9-6.3,2.4-5.2,and 2.6-5.7%,respectively.If the N rate is reduced to the WFFP level in each county,the NUEs of the three crops will increase by 12.9-19.5%,and the N leaching,NH3,and N2O emissions will be reduced by 48.9-56.2,37.4-42.9,and 46.0-66.5%,respectively.Our findings highlight that efficient N management practices in sustainable intensive farmland have considerable potential for reducing environmental impacts.

文摘Neuropathic pain,often featuring allodynia,imposes significant physical and psychological burdens on patients,with limited treatments due to unclear central mechanisms.Addressing this challenge remains a crucial unsolved issue in pain medicine.Our previous study,using protein kinase C gamma(PKCγ)-tdTomato mice,highlights the spinal feedforward inhibitory circuit involving PKCγ neurons in gating neuropathic allodynia.However,the regulatory mechanisms governing this circuit necessitate further elucidation.We used diverse transgenic mice and advanced techniques to uncover the regulatory role of the descending serotonin(5-HT)facilitation system on spinal PKCγ neurons.Our findings revealed that 5-HT neurons from the rostral ventromedial medulla hyperpolarize spinal inhibitory interneurons via 5-HT_(2C) receptors,disinhibiting the feedforward inhibitory circuit involving PKCγ neurons and exacerbating allodynia.Inhibiting spinal 5-HT_(2C) receptors restored the feedforward inhibitory circuit,effectively preventing neuropathic allodynia.These insights offer promising therapeutic targets for neuropathic allodynia management,emphasizing the potential of spinal 5-HT_(2C) receptors as a novel avenue for intervention.

文摘When benefiting other beneficiaries,cushion plants may reciprocally receive feedback effects.The feedback effects on different sex morphs,however,remains unclear.In this study,taking the gynodioecious Arenaria polytrichiodes as a model species,we aimed to assess the sex-specific facilitation intensity of cushion plant by measuring the beneficiary cover ratio,and to assess the potential costs in cushion reproductive functions by measuring the flower and fruit cover ratios.The total beneficiary cover ratio was similar between females and hermaphrodites.Females produced much less flowers but more fruits than hermaphrodites.These results suggested that females and hermaphrodites possess similar facilitation intensity,and female cushion A.polytrichoides may allocate more resources saved from pollen production to seed production,while hermaphrodites possibly allocate more resources to pollen production hence reducing seed production.The surface areas covered by beneficiaries produced less flowers and fruits than areas without beneficiaries.In addition,strong negative correlations between beneficiary cover and flower cover were detected for both females and hermaphrodites,but the correlation strength were similar for these two sex morphs.However,the correlation between beneficiary cover and fruit cover was only significantly negative for females,suggesting that beneficiary plants negatively affect fruit reproduction of females while have neutral effects on hermaphrodites.All the results suggest that to facilitate other beneficiaries can induce reproductive costs on cushion A.polytrichoides,with females possibly suffering greater cost than hermaphrodites.Such differentiation in reproductive costs between sex morphs,in long-term perspective,may imply sex imbalance in population dynamics.
文摘Objective To evaluate short time effects of primary percutaneous coronary intervention (pPCI) and rtPA thrombolysis+PCI (rtPA+PCI) on myocardial viability and ventricular systolic synchrony in AMI patients.Methods Eighty seven patients with first AMI were divided into two groups: group A ( n =42), pPCI group, the patients underwent PCI within 6h after onset of AMI; group B ( n =45), rtPA+PCI group, the patients underwent PCI after thrombolysis within 6h after onset of AMI; Myocardial viability was measured by 99m Tc MIBI SPECT. While, the parameters of cardiac function LVEF and ventricular systolic synchrony LVPS were measured by 99m Tc gated cardiac blood pool image on the first and the fourth weekend. Results (1) The peak CK MB was significantly lower in group A than that in group B( P <0.01 ). (2) Myocardial infarction area (MIA) was decreased and radioactivity counts in MIA was significantly increased in group A and B on the 4th weekend compared with that on the first weekend ( P <0.01 ), but there were no significant difference between group A and group B. (3) LVEF, LVPS were no significant difference between group A and group B.Conclusions (1)pPCI in acute myocardial infartion can limit infarct area, maintain ventricular systolic synchrony and improve ventricular function; (2) but, in those hospitals that there were no any condition for PCI, they should transfer the patients to central hospital for PCI after thrombolysis at the first time. It is beneficial to improve myocardial viability and ventricular systolic synchrony of AMI patients in short time.
文摘Objectives:Effective facilitation is crucial to improve critical care outcomes in life-threatening conditions through improved teamwork,caring,decision-making,and problem-solving.The meaning of facilitation remains unprecise in a critical care context despite its frequent usage in nursing education and clinical practice.This study aimed to report a thorough concept analysis to clarify the meaning of facilitation in the critical care context by formulating attributes,antecedents,and consequences and providing model cases related to facilitation.Methods:This analysis was performed by searching online sources published from 1999 to 2023.EBSCOhost,CINAHL,PubMed,and Google Scholar databases were searched using online search engines.The analysis also included the manual search of books,thesaurus and dictionaries that showed relevance to facilitation.Walker and Avant’s eight-step approach was applied to explore and analyze the meaning of facilitation in critical care units.Results:A total of 68 articles were included in the analysis of this study.Eleven attributes,six antecedents,and seven consequences related to facilitation were formulated.The attributes included dynamic,interactive processes,creating a positive environment,mobilizing resources,assistance,studentcentered,shared goals,collaboration,engagement,participation,and feedback.Antecedents were facilitator qualities,motivation,a positive learning environment,student-facilitator relationship,time availability,and specified learning outcomes.The consequences of facilitation were identified as follows:change,professional development,competency,quality development,increased job satisfaction,staff retention,and self-confidence.Conclusions:The findings from the analysis indicated that effective facilitation results in nurses and critical care staff developing competency,caring,critical thinking,and independence.Therefore,clinical outcomes in critical care environments are improved through teamwork,decision-making,and problemsolving in life-threatening situations.

文摘CO2 separation performance in facilitated transport membranes has been reported depended not only on the CO2 carrier properties but also to a great extent on the polymeric matrix regarding the capacity of retaining water and carriers as well as the processability for coating defect-free ultra-thin films. In this study, the blends of hydrophilic polymers polyvinyl pyrrolidone(PVP) and polyvinyl alcohol(PVA) were studied to find an optimal polymer matrix to host carriers in facilitated transport membranes for enhanced CO2 separation. It is found out that the optimized blend is 50/50 PVA/PVP by weight, which shows a significant increase in the water uptake(from 63 to 84%) at equilibrium state compared to the neat PVA. Polyethyleneimine(PEI) was employed to provide sample carriers to evaluate the synergistic effect of PVA and PVP on the CO2 separation performance. A thin film composite(TFC) membrane of the optimized blend(50/50 PVA/PVP with 50 wt% PEI) was fabricated on polysulfone(PSf) porous support. The fabrication of the TFC membranes is simple and low cost, and CO2 permeance of the optimized blend membrane is nearly doubled with the CO2/N2 selectivity remained unchanged, showing great potential for industrial applications of the resulted membranes.

文摘C3 plant Reaumuria soongorica and C4 plant Salsola passerina are super xerophytes and coexist in a mixed community in either isolated or associated growth, and interspecific facilitation occurs in associated growth. In the present study, the root traits including root distribution, root length（RL）, root surface area（RSA）, root weight（RW） and specific root length（SRL） of both species in two growth forms were investigated to clarify their response to facilitation in associated growth. Six isolated plants of each species, as well as six associated plants similar in size and development were selected during the plant growing season, and their roots were excavated at 0–10, 10–20, 20–30, 30–40 and 40–50 cm soil depths at the end of the growing season. All the roots of each plant were separated into the two categories of fine roots（2 mm diameter） and coarse roots（≥2 mm diameter）. Root traits such as RL and RSA in the fine and coarse roots were obtained by the root analyzing system WinRHIZO. Most of the coarse roots in R. soongorica and S. passerina were distributed in the top 10 cm of the soil in both growth forms, whereas the fine roots of the two plant species were found mainly in the 10–20 and 20–30 cm soil depths in isolated growth, respectively. However, the fine roots of both species were mostly overlapped in 10–20 cm soil depth in associated growth. The root/canopy ratios of both species reduced, whereas the ratios of their fine roots to coarse roots in RL increased, and both species had an increased SRL in the fine roots in associated growth. In addition, there was the increase in RL of fine roots and content of root N for S. passerina in associated growth. Taken together, the root growth of S. passerina was facilitated for water and nutrient exploration under the interaction of the overlapped roots in both species in associated growth, and higher SRL allowed both species to more effectively adapt to the infertile soil in the desert ecosystem.
