为有效利用桃渣资源,该试验采用醇沉法提取桃渣中的膳食纤维,采用气流粉碎、臼式研磨和离心研磨3种方式处理桃渣膳食纤维,并对其理化性质及结构特性进行评价。结果表明,3种粉粹方式未引起桃渣膳食纤维的晶体结构及官能团的改变。离心研磨粉体的粒径最大,臼式研磨次之,气流粉碎后粉体表面粗糙、粒径最小为9.46μm。随着粉碎粒径的减小,粉体的持水持油能力、溶胀性、阳离子交换能力显著增加(P<0.05)。气流粉碎后DPPH自由基和ABTS阳离子自由基清除率IC_(50)值分别为0.48 mg/mL和2.25 mg/mL。亚硝酸盐吸附能力达394.93μg/g显著高于其他2种处理方式(P<0.05)。与臼式研磨和离心研磨粉碎方式相比较,气流粉碎具有较好的理化和功能特性。该研究结果可为获得高质量的桃渣膳食纤维粉提供数据支撑。

本文报告了1例右下肺癌术后发生支气管胸膜瘘(BPF)的患者病例,分析了其临床特点、诊治过程以及临床经验。患者于2019年10月15日行胸腔镜右下肺切除术,术后2个月出现反复发热、咳嗽,多次抗感染治疗无效。经胸部增强CT、NGS和脓液培养等多种手段最终确诊为BPF合并脓胸。先接受了内镜下Amplatzer装置封堵瘘口治疗,后发现残余腔感染未完全吸收。随后行全麻下支气管瘘闭合术+游离皮瓣移植术+肌肉游离移植术+胸廓成形术+支气管修补术+胸腔闭式引流术+胸膜病损切除术+皮瓣转移术+肋骨部分切除术等多学科治疗后症状明显改善,且随访6个月无复发症状。对于BPF患者,不仅要充分控制感染和封堵瘘管,还要消除脓胸腔。此外,内窥镜Amplatzer装置封堵、开窗造口术和肌瓣移植等多学科合作是治疗BPF合并脓胸的有效选择。

Global climate change has led to the decline of species and functional diversity in ecosystems,changing community composition and ecosystem ***,we still know little about how species with different resource-use strategies(different types of resource usage and plant growth of plants as indicated by the spectrum of plant economic traits,including acquisitive resource-use strategy and conservative resource-use strategy)would change in response to climate change,and how the changes in the diversity of species with different resource-use strategies may influence community-level ***,using long-term(1982–2017)observatory data in a temperate grassland in Inner Mongolia,we investigated how climate change had affected the species richness(SR)and functional richness(FRic)for the whole community and for species with different resource-use ***,based on data for four traits representing leaf economics spectrum(leaf carbon concentration,leaf nitrogen concentration,leaf phosphorus concentration,and specific leaf area),we divided 81 plant species appearing in the grassland community into three plant functional types representing resource-acquisitive,medium,and resource-conservative *** then analyzed the changes in community-level productivity in response to the decline of SR and FRic at the community level and for different resource-use *** found that community-level SR and FRic decreased with drying climate,which was largely driven by the decline of diversity for resource-acquisitive ***,community-level productivity remained stable because resource-conservative species dominating this grassland were barely affected by climate *** study revealed distinctive responses of species with different resource-use strategies to climate change and provided a new approach based on species functional traits for predicting the magnitude and direction of climate change effects on ecosystem functions.

The experiment was conducted to investigate the effects of compound plant extract on the growth performance and economic benefits of Sujiang pigs during the fattening period. A total of 50 Sujiang pigs,weighing about 60 kg( there were no significant differences in the weight of the pigs),were selected. They were randomly and evenly divided into five groups: control group,A,B,C and D groups. The pigs in the control group were fed basal diet. For the pigs in the A,B,C and D groups,per kg of basal diet was added with 100,200,300 and 400 mg of compound plant extract,respectively. The experimental duration was 44 d. The results showed that in the treatment groups,the average daily weight gains were 15. 57%,20. 68%,17. 95% and 7. 31%,respectively higher than that of the control group,the feed-gain ratios were13. 29%,16. 92%,15. 11% and 11. 48%,respectively lower than that of the control group( P > 0. 05),and the economic benefits were62. 65,83. 23,72. 50 and 42. 11 yuan,respectively higher than that of the control group. In conclusion,the addition of compound plant extract in the basal diet of Sujiang pigs during fattening period can improve the economic benefit,and the economic benefit is best when the addition amount is 200 mg/kg.

Poor quality embryos discarded from in vitro fertilization （IVF） laboratories are good sources for deriving human embryonic stem cell （hESC） lines. In this study, 166 poor quality embryos donated from IVF centers on day 3 were cultured in a blastocyst medium for 2 days, and 32 early blastocysts were further cultured in a blastocyst optimum culture medium for additional 2 days so that the inner cell masses （ICMs） could be identified and isolated easily. The ICMs of 17 blastocysts were isolated by a mechanical method, while those of the other 15 blastocysts were isolated by immunosurgery. All isolated ICMs were inoculated onto a feeder layer for subcultivation. The rates of ICM attachment, primary ICM colony formation and the efficiency of hESC derivation were similar between the ICMs isolated by the two methods （P〉0.05）. As a result, four new hESC lines were established. Three cell lines had normal karyotypes and one had an unbalanced Robertsonian translocation. All cell lines showed normal hESC characteristics and had the differentiation ability. In conclusion, we established a stable and effective method for hESC isolation and culture, and it was confirmed that the mechanical isolation was an effective method to isolate ICMs from poor embryos. These results further indicate that hESC lines can be derived from poor quality embryos discarded by IVF laboratories.
