有机胺水溶液吸收法是CO_(2)捕集最常用且成熟的方法之一,但是再生能耗高和吸收剂严重降解等关键问题阻碍了其大规模推广和应用。采用有机溶剂代替强极性水溶剂构建的非水吸收剂体系,在降低能耗方面具有巨大潜力,在近年来受到格外关注。非水吸收剂的CO_(2)吸收动力学研究有助于了解吸收过程的反应机理以及不同有机胺和溶剂类型对反应动力学的影响。本文从有机胺在非水溶剂中的反应机理出发,介绍了CO_(2)吸收动力学研究的典型实验方法和原理,系统评述了采用不同结构的有机胺在不同溶剂体系中吸收CO_(2)的动力学研究进展,深入分析了溶剂特性与胺的反应级数和反应动力学常数之间的关联性,并指出了普遍的规律性特征即有机伯胺和仲胺的反应级数随溶剂极性的降低而增大,反应速率常数随着溶剂的溶解度参数增大而呈现近似线性变化。在分析目前动力学研究中存在的问题基础上,对今后非水体系动力学的研究方向进行了展望。

OBJECTIVE: To determine the clinical efficacy and safety of Liangxue Jiedu decoction(LJD) for the treatment of progressive psoriasis vulgaris and to provide the basis for the development of a standardized treatment protocol for psoriasis ***: In this multicenter, randomized, controlled study, patients with blood-heat type psoriasis were randomly assigned to receive either Chinese herbal medicine(LJD;treatment group) or Western Medicine(cetirizine hydrochloride, vitamin C, and vitamin B complex;control group). Psoriasis Area and Severity Index(PASI) scores were calculated in addition to the number of patients who achieved ≥ 50% or ≥ 75% improvement in PASI score from baseline. The change in symptoms of Chinese medicine(color of rash, burning sensation,itchiness, severity of irritation, and anger) was evaluated and safety was assessed as adverse events and laboratory analysis. t test, independent sample non-parametric test and χ2 test were used to analyze the ***: A total of 238 participants were included in the study [treatment group, n = 122(PP analysis117);control group, n = 116(PP analysis 104)]. LJD treatment was associated with a significant improvement in skin lesions and symptoms com-pared with Western Medicine treatment. At the end of the 8-week treatment period, 23.77%(PP analysis 24.79%) of patients in the treatment group had achieved PASI75 and 57.38%(PP analysis 58.97%)had achieved PASI50;the corresponding figures in the control group were 9.48%(9.62%) and 25.00%(25.00%), respectively. The between-group differences were statistically significant(P < 0.05).CONCLUSION: Treatment of psoriasis vulgaris of the blood-heat type using LJD was associated with significantly better outcomes compared with those achieved using standard Western Medicine.

Background: A simplified protocol for regional citrate anticoagulation (RCA) using a commercial calcium-containing replacement solution, without continuous calcium infusion, is more efficient for use in continuous renal replacement therapy (CRRT). We aim to design a randomized clinical trial to compare the safety and efficacy between calcium-free and calcium-containing replacement solutions in CRRT with ***: Of the 64 patients receiving RCA-based postdilution continuous venovenous hemodiafiltration (CVVHDF) enrolled from 2017 to 2019 in West China Hospital of Sichuan University, 35 patients were randomized to the calcium-containing group and 29 to the calcium-free replacement solution group. The primary endpoint was circuit lifespan and Kaplan-Meier survival analysis was performed. Secondary endpoints included hospital mortality, kidney function recovery rate, and complications. The amount of 4% trisodium citrate solution infusion was recorded. Serum and effluent total (tCa) and ionized (iCa) calcium concentrations were measured during ***: A total of 149 circuits (82 in the calcium-containing group and 67 in the calcium-free group) and 7609 circuit hours (4335 hvs. 3274 h) were included. The mean circuit lifespan was 58.1 h (95% CI 53.8-62.4 h) in the calcium-containing groupvs. 55.3 h (95% CI 49.7-60.9 h, log rankP = 0.89) in the calcium-free group. The serum tCa and iCa concentrations were slightly lower in the calcium-containing group during CRRT, whereas the postfilter iCa concentration was lower in the calcium-free group. Moreover, the mean amounts of 4% trisodium citrate solution infusion were not significantly different between the groups (171.1 ± 15.9 mL/hvs. 169.0 ± 15.1 mL/h,P = 0.49). The mortality (14/35 [40%]vs. 13/29 [45%],P = 0.70) and kidney function recovery rates of AKI patients (19/26, 73%vs. 14/24, 58%,P = 0.27) were comparable between the calcium-containing and calcium-free group during hospitalization, respectively.

OBJECTIVE: To investigate the efficacy and safety of Traditional Chinese Medicine (TCM) therapy combined with ultraviolet B light therapy in the treatment of moderate-to-severe psoriasis. METHODS: Patients with moderate-to-severe psoriasis (skin lesion area > 10% of the body surface area) for 2 consecutive years were treated with TCM (oral and external use of herbal medicines, acupuncture, and herbal bathing) and narrow-band medium-wave ultraviolet B light treatment for 12 weeks. The treatment effect was evaluated based on the Psoriasis Area Severity Index (PASI), the achievement of a 50% reduction in the PASI (PASI50), the achievement of a 75% reduction in the PASI (PASI75), pruritus score, Dermatology Life Quality Index, and safety. RESULTS: A total of 95 outpatients were enrolled, and 92 subjects (96.8%) completed the 12-week treatment course. At baseline, the average proportion of the body surface area covered by skin lesions was 12.4%, and the average PASI was 17.7. All patients had previously been treated with conventional medicine (89.1% of patients received ultraviolet light treatment, 50.0% received glucocorticoids, and 21.7% received acitretin). After the 12-week treatment course, 22 patients (23.9%) achieved PASI75, and 43 (46.7%) achieved PASI50. The post-treatment pruritus score and Dermatology Life Quality Index of all treated patients were significantly lower than the respective baseline values (P < 0.0001). No adverse effects were detected by the monitoring of blood, urine, stools, liver and kidney function, and ***: Comprehensive therapy comprising TCM therapy combined with ultraviolet B light therapy achieved good outcomes for patients with moderate-to-severe psoriasis.

协同显著性检测指从一组相关图像集中识别出共同出现且显著的物体,其难点是如何挖掘与利用图像帧内、帧间的显著性线索.文中提出一种统一分级图神经网络的协同显著性检测方法.首先利用超像素分割算法将图像分割,并提取图像帧内分级显著性特征构建图模型;然后挖掘图像帧间分级显著性图嵌入,形成统一的二维分级特征体系;最后充分利用图像帧内和图像帧间的线索,提出几何注意力模块.在iCoSeg数据集上的消融实验结果表明,所提出的统一分级图神经网络中各个模块均是有效的;所提方法基于iCoSeg数据集测试的最大F-measure、平均绝对误差以及S-measure分别为0.8486,0.1076和0.8134,可以媲美或优于其他9种对比方法,最终获得的显著性图的高亮一致性和边缘均得到明显的改善.

世界经济环境不确定性背景下汇率风险将冲击国内实体经济,企业外汇风险感知是否抑制企业投资扩张是我国防范外部风险输入引发国内经济风险所面临的重要问题。本文采用世界银行企业调查的跨国数据,利用企业层面关于外汇风险感知的主观评价指标,实证检验外汇风险感知对企业投资扩张的影响,并进一步分析国家宏观制度的调节效应。实证结果发现:(1)外汇风险感知将显著抑制企业投资扩张,这一结果在考虑内生性、指标选取、模型设定等问题后仍然稳健;(2)企业的风险预期、投资不可逆性以及融资约束程度越高,企业投资扩张受到外汇风险感知的抑制作用越明显;(3)一国具有较高金融发展水平、较低汇率制度弹性、较低资本开放程度以及更高效的中央银行调控政策与国家治理水平,外汇风险感知对企业投资的抑制作用将会被削弱。
