In the competitive energy market,energy retailers are facing the uncertainties of both energy price and demand,which requires them to formulate reasonable energy purchasing and selling strategies for improving their competitiveness in this ***,the attractive multi-energy retail packages are the key for retailers to increase their ***,combined with incentive means and price signals,five types of multi-energy retail packages such as peak-valley time-of-use(TOU)price package and day-night bundled price package are designed in this paper for *** iterative interactions between retailers and end-users are modeled using a bi-level model of stochastic optimization based on multi-leader multi-follower(MLMF)Stackelberg game,in which retailers are leaders and end-users are *** make decisions to maximize the profit considering the conditional value at risk(CVaR)while end-users optimize the satisfaction of both energy comfort and ***,a distributed algorithm is proposed to obtain the Nash equilibrium of above MLMF Stackelberg game model while the particle swarm optimization(PSO)algorithm and CPLEX solver are applied to solve the optimization model for each participant(retailer or end-user).Numeral results show that the designed retail packages can increase the overall profit of retailers,and the overall satisfaction of industrial users is the highest while that of residential users is the lowest after game interaction.

目的观察鼻咽清毒颗粒(BQG)对放疗引起大鼠口腔黏膜损伤的保护作用,并探讨其可能的作用机制。方法采用FAT细胞皮下注射法,建立F344大鼠种植瘤模型。F344大鼠分为对照组、对照放射组、模型组、BQG低、中、高剂量(1、2、4 g·kg^(−1))组。除对照组外,各组动物进行X线照射,放射剂量为10 Gy·d^(−1),连续5 d。BQG 3个剂量组于第1天造模后进行药物干预,每天ig给药1次,连续28 d;其余3组给予等体积的蒸馏水。每日对各组大鼠进行一般观察,定期进行称重。末次给药后24 h处死大鼠,采集各组大鼠口腔黏膜及血浆,酶联免疫吸附实验(ELISA)检测大鼠血浆中白细胞介素-6(IL-6)、白细胞介素-1β(IL-1β)、肿瘤坏死因α(TNF-α)水平;Western blotting检测口腔黏膜NF-κB p65、p-P65、MAPK、ERK、p-ERK等蛋白表达情况,并对其进行组织病理学检查。结果BQG低、中、高剂量组均能提高大鼠体质量增长率;BQG各给药组能显著降低口轻黏膜组织中IL-6、IL-1β、TNF-α水平(P<0.05、0.01);与模型组比较,BQG各给药组MAPK蛋白表达显著降低,p-p65/p65,p-ERK/ERK比值显著降低(P<0.05、0.01)。结论BQG对放射性口腔黏膜炎具有修复作用,其可能通过调控NF-κB/MAPK/ERK信号通路,降低口腔黏膜炎症因子水平相关。

Previous studies have shown that sympathetic nerves are related to certain types of pain, and this phenomenon is referred to as sympathetic-sensory coupling. Chronic pain resulting from nerve injury can be exacerbated by sympathetic stimulation or relieved by sympathetic inhibition. In the present study, the correlation between pain and sympathetic nerves was analyzed in patients with severe pain in lower limbs, as we^l as in a chronically compressed dorsa~ root ganglion ~CCD） rat model （model of low back pain and sciatica）. Patients with severe pain in the lower limbs underwent chemical lumbar sympathectomy （CLS）, and the analgesic effects of CLS were compared with painkillers. Results demonstrated significantly relieved lower limb pain following CLS, and the analgesic effects of CLS were superior to those seen with painkillers. In the CCD rat model, dorsal root ganglion neuronal activity significantly increased as a result of electrical stimulation to the sympathetic nerves. These results suggest that sympathetic nerves are closely associated with pain and sympathetic-sensory coupling is likely in lower limb pain in both patients and rat models of CCD.

Three gas separation technologies,chemical absorption,membrane separation and pressure swing adsorption,are usually applied for CO2 capture from flue gas in coal-fired power *** this work,the costs of the three technologies are analyzed and *** cost for chemical absorption is mainly from $30 to $60 per ton(based on CO2 avoided),while the minimum value is $10 per ton(based on CO2 avoided).As for membrane separation and pressure swing adsorption,the costs are $50 to $78 and $40 to $63 per ton(based on CO2 avoided),*** are proposed to reduce the cost of the three *** CO2 capture and storage process,the CO2 recovery and purity should be greater than 90%.Based on the cost,recovery,and purity,it seems that chemical absorption is currently the most cost-effective technology for CO2 capture from flue gas from power ***,membrane gas separation is the most promising alternative approach in the future,provided that membrane performance is further improved.

目的应用营养风险筛查表2002(NRS2002)评分和微型营养评估简表(MNA-SF)评分两种营养筛查工具评估高龄住院患者的营养状况,并评价两种营养筛查工具的适用性。方法采用随机抽样的方法,对>80岁住院患者进行一般资料采集。根据年龄将其分为≥90岁组和<90岁组两个年龄组,应用两种营养筛查工具进行营养状况评估。同时测定空腹静脉血营养相关指标水平,包括白蛋白(Alb)、血红蛋白(Hb)、C反应蛋白(CRP)、转铁蛋白(TRF)、前白蛋白(PA)和视黄醇结合蛋白(RBP),并将结果进行相关性分析。结果NRS2002评分评估有营养不良风险的患者为404例(48.56%),≥90岁组的营养不良风险发生率高于<90岁组(P<0.01);MNA-SF评分评估营养不良/有营养不良风险的患者为616例(74.04%),≥90岁组的营养不良风险发生率高于<90岁组(P<0.01)。以血清Alb<30 g/L作为参考标准,比较两种营养筛查工具的适用性,发现两种营养筛查工具均适用于高龄住院患者营养状况筛查,且NRS2002评分评估高龄住院患者的营养状况的受试者工作特征(ROC)曲线下面积(AUC)为0.805,灵敏度和特异度分别为88.6%和62.2%,MNA-SF评分评估高龄住院患者的营养状况的ROC AUC为0.814,灵敏度和特异度分别为75.7%和87.7%。分析Hb、CRP、PA、RBP、TRF生化指标与MNA-SF评分和NRS2002评分相关性,结果显示NRS2002评分和MNA-SF评分与PA、RBP和TRF具有相关性。结论高龄住院患者出现营养不良风险的发生率高。NRS2002评分和MNF-SF两种营养筛查工具均适用于高龄住院患者,且具有较高准确性,同时联合营养相关指标评估高龄患者营养状况可提高营养评估的精准性。
