BACKGROUND Fecal microbiota transplantation(FMT)is a promising therapeutic approach for treating Crohn’s disease(CD).The new method of FMT,based on the automatic washing process,was named as washed microbiota transplantation(WMT).Most existing studies have focused on observing the clinical ***,the mechanism of action of FMT for the effective management of CD-particularly in-depth multi-omics analysis involving the metagenome,metatranscriptome,and metabolome-has not yet been *** To assess the efficacy of WMT for CD and explore alterations in the microbiome and metabolome in response to *** We conducted a prospective,open-label,single-center clinical *** CD patients underwent *** clinical responses(defined as a decrease in their CD Activity Index score of>100 points)and their microbiome(metagenome,metatranscriptome)and metabolome profiles were evaluated three months after the *** Seven of the 11 patients(63.6%)showed an optimal clinical response three months *** microbiome diversity significantly increased after WMT,consistent with improved clinical *** of the metagenome and metatranscriptome analyses revealed consistent alterations in certain strains,such as Faecalibac-terium prausnitzii,Roseburia intestinalis,and Escherichia *** addition,metabolomics analyses demonstrated that CD patients had elevated levels of various amino acids before treatment compared to the ***,levels of vital amino acids that may be associated with disease progression(e.g.,L-glutamic acid,gamma-glutamyl-leucine,and prolyl-glutamine)were reduced after *** WMT demonstrated therapeutic efficacy in CD treatment,likely due to the effective reconstruction of the patient’s ***-omics techniques can effectively help decipher the potential mechanisms of WMT in treating CD.

To develop suitable grouting materials for water conveyance tunnels in cold regions, firstly, this study investigated the performance evolution of ferrite-rich sulfoaluminate-based composite cement (FSAC grouting material) at 20 and 3 °C. The results show that low temperature only delays the strength development of FSAC grouting material within the first 3 d. Then, the effect of four typical early strength synergists on the early properties of FSAC grouting material was evaluated to optimize the early (≤1 d) strength at 3 °C. The most effective synergist, Ca(HCOO)2, which enhances the low-temperature early strength without compromising fluidity was selected based on strength and fluidity tests. Its micro-mechanism was analyzed by XRD, TG, and SEM methods. The results reveal that the most suitable dosage range is 0.3 wt%–0.5 wt%. Proper addition of Ca(HCOO)2 changed the crystal morphology of the hydration products, decreased the pore size and formed more compact hydration products by interlocking and overlapping. However, excessive addition of Ca(HCOO)2 inhibited the hydration reaction, resulting in a simple and loose structure of the hydration products. The research results have reference value for controlling surrounding rock deformation and preventing water and mud inrushes during the excavation in cold region tunnels.

社会转型与移动性背景下,个体与社区环境的互动方式不断重构,社区归属感的形成路径更加复杂。基于此,本文利用上海市居民活动与出行调查数据,建立公共接触潜力的广度、强度和跨群体接触指数测度居民的社区活动空间共享特征,运用有序logit模型探究社区环境、活动空间共享对居民社区归属感的影响。研究发现:①公共接触潜力广度和跨收入群体公共接触潜力对社区归属感具有负向影响,跨户口群体公共接触潜力具有正向影响,公共接触潜力强度影响不显著。②社区外来人口比例较高有利于提升社区归属感,说明社区社会组成多样有利于提升对社区的情感依赖。③社区环境感知对社区归属感具有正向影响,商品房居民比其他社区居民更有可能表现出高社区归属感。④本地、中收入、已婚和拥有住房产权的居民更有可能对社区产生情感依赖,但日常活动远离社区的人更难建立起对社区的情感。本文提出通过活动空间共享深化移动性背景下社区促进社会融合的机制研究,丰富社区社会融合理论,为构建包容性城市和促进高质量发展提供参考。

This study discusses the composition analysis and comparison of Jaboticaba under different processing conditions for fermented liquid, jam, fruit powder, and fruit vinegar. The differences and comparison of the contents of total polyphenols, anthocyanins, resveratrol, superoxide dismutase, small molecular peptides and ellagic acid in their products were analyzed. After analysis and comparison of results, the content of total polyphenols was found to be the highest 44.82 ± 0.89 (mg/g) after being fermented directly from fresh fruit. The fresh fruit was dried at low temperature and ground into powder, with a maximum ellagic acid content of 12.799 ± 0.12 (mg/g). Fresh fruit was then made into jam, with the highest anthocyanin content of 57.39 ± 1.20 (mg/g). The fruit vinegar was produced by fermentation. Except for the content of small molecule peptides, which was similar to the content of fermentation broth and fruit powder, they were 20.63 ± 1.61, 23.84 ± 2.51 and 20.52 ± 1.21 (mg/g), and the rest of the composition was not as good as other samples. In the fresh fruit fermentation broth samples, resveratrol was produced and detected, and its content was 2.14 (mg/L), while it was not detected in other samples, and a superoxide dismutase (SOD)-like enzyme was detected in the fresh fruit fermentation broth. The highest activity was 49002.5 units/mL. Jaboticaba is prepared using a fermentation broth processing method with fresh fruit, and its total polyphenol content is higher than that of fruit powder, jam, and fruit vinegar. The commercial value of Jaboticaba and the establishment of composition content data are relatively improved, which is more promising for the future.

Background: Benign prostatic hyperplasia (BPH) is the proliferation of the stromal and epithelial cells of the prostate gland, resulting in an increase in its size. This may result in obstruction of the lower urinary tract causing storage and voiding symptoms. Methods: This was a prospective cross-sectional study from August 2020 to July 2021, to evaluate the characteristic of patients presenting to the tamale Teaching Hospital with lower urinary tract symptoms secondary to BPH. Results: The median age at presentation with LUTS secondary to BPH is 68.88 ± 11.10 years with an average prostate volume of 70 g. The average time of presentation to the hospital is 5 months, mostly with moderate to severe symptoms. Correlation between Prostate volume (PV) and age yielded a positive relationship;however, this was not statistically significant, (r = 0.028, p-value = 0.747). There was a significant positive relationship between PV and the IPSS score, (r = 0.334, p-value Conclusion: Our patients with symptomatic BPH present at age 60 years and above, with nearly all of them presenting with moderate to severe LUTS.
