Alleviation of refractory IgA nephropathy by intensive fecal microbiota transplantation: the first case reports

Jin Zhao, Ming Bai, Xiaoxia Yang, Yan Wang, Rong Li & Shiren Sun
Gut dysbiosis may be implicated in the pathogenesis of IgA nephropathy (IgAN) through immune and/or metabolite pathways. Fecal microbiota transplantation (FMT) could reestablish the micro-ecological balance in IgAN, although this has never been attempted before. We explored whether FMT could be efficacious in treating IgAN in two patients with refractory IgAN. Two Chinese female patients with IgAN failed to achieve clinical remission after receiving several rounds of immunosuppressive therapy and suffered from unbearable adverse effects...

Whole-transcriptome analysis of rat cavernosum and identification of circRNA-miRNA-mRNA networks to investigate nerve injury erectile dysfunction pathogenesis

Jie Huang, Jianxiong Ma, Jie Wang, Ke Ma, Kang Zhou, Wenjie Huang, Fan Zhao, Bodong Lv & Qing Hu
There is growing evidence that circular RNAs (circRNAs) play a vital role in many kinds of diseases, including erectile dysfunction (ED). Nevertheless, the role of circRNAs in cavernous nerve-damaging ED (CNI-ED) is unknown. Here, we aimed to discover novel circRNAs, probed their potential role in the CNI-ED, and construct a ceRNA network of circRNAs. Twelve male Sprague Dawley rats were randomly divided into 2 groups by us: bilateral cavernous nerve crush (BCNC) and control groups....

Identification of downstream targets and signaling pathways of long non-coding RNA NR_002794 in human trophoblast cells

Yinyao Ma, Hua Wu, Xuxia Liang, Chun Zhang, Yanhua Ma, Yanfen Wei, Jing Li & Hui Chen
Preeclampsia (PE) is a huge threat to pregnant women. Our previous study demonstrated that long non-coding RNA (lncRNA) NR_002794 was highly expressed in placentas of PE patients and could regulate the phenotypes of trophoblast cells. However, the downstream regulatory mechanisms of NR_002794 remain unknown. In this text, some potential downstream targets or signaling pathways of NR_002794 were identified through RNA sequencing (RNA-seq) and bioinformatics analysis in SWAN71 trophoblast cells. Western blot assay demonstrated that NR_002794...

miR-146b-5p regulates bone marrow mesenchymal stem cell differentiation by SIAH2/PPARγ in aplastic anemia children and benzene-induced aplastic anemia mouse model

Huanhuan Li, Xueju Xu, Dao Wang, Li Zeng, Bai Li, Yuan Zhang, Shufang Su, Linlin Wei, Hongliang You, Yingqi Fang, Yingchao Wang & Yufeng Liu
This study aimed to reveal the mechanism of miR-146b-5p in the differentiation of bone marrow mesenchymal stem cells (BMSCs) derived from children with aplastic anemia (AA). Here, we found that miR-146b-5p was highly expressed in BMSCs from children with AA, and the BMSCs surface markers expressions in BMSCs derived from children with AA and the healthy controls exerted no significant differences. Besides, the overexpression of miR-146b-5p in normal human-derived BMSCs promoted the adipogenic differentiation of...

Network analysis of PTSD in college students across different areas after the COVID-19 epidemic

Rui Sun, Junjun Qi, Jiali Huang & Xiao Zhou
Background: Various studies have examined the psychological ‘typhoon eye’ and ‘ripple’ effects in mental disorders following COVID-19. However, these studies only considered the disorders as entities and assessed severity, and overlooked the differences in specific symptoms of disorders. Objectives: This aim of the study is to assess the psychological typhoon eye and ripple effects at the symptom-level in posttraumatic stress disorder (PTSD), which is considered as a common psychopathology following the COVID-19 epidemic. Method: In...

Potential biomarkers for inherited thrombocytopenia 2 identified by plasma proteomics

Xiaojie Wang, Maoshan Chen, Limeng Dai, Chengning Tan, Lanyue Hu, Yichi Zhang, Yanni Xiao, Fengjie Li, Cheng Zeng, Zheng Xiang, Yali Wang, Weiwei Zhang, Xiaomei Zhang, Qian Ran, Zhongjun Li & Li Chen
Inherited thrombocytopenia 2 (THC2) is difficult to diagnose due to the lack of specific clinical characteristics and diagnostic methods. To identify potential plasma protein biomarkers for THC2, we collected the plasma samples from a THC2 family (9 THC2 and 15 non-THC2 members), enriched the medium and low abundant proteins using Proteominer and analyzed the protein profiles using the liquid chromatography-mass spectrometry in data independent acquisition mode. Initially, we detected 784 proteins in the plasma samples...

[\"Complexation of a guanidinium-modified calixarene with diverse dyes and investigation of the corresponding photophysical response\"]

Yu-Ying Wang, Yong Kong, Zhe Zheng, Wen-Chao Geng, Zi-Yi Zhao, Hongwei Sun & Dong-Sheng Guo
We herein describe the comprehensive investigation of the complexation behavior of a guanidinium-modified calix[5]arene pentaisohexyl ether (GC5A) with a variety of typical luminescent dyes. Fluorescein, eosin Y, rose bengal, tetraphenylporphine sulfonate and sulfonated aluminum phthalocyanine were employed as classical aggregation-induced quenching dyes. 2-(p-Toluidinyl)naphthalene-6-sulfonic acid and 1-anilinonaphthalene-8-sulfonic acid were selected as representatives of intramolecular charge-transfer dyes. Phosphated tetraphenylethylene was involved as the classical aggregation-induced emission dye. Sulfonated acedan representing one example of two-photon fluorescent probes, was...

Dong-Sheng Guo, Yu Liu & Li-Hua Wang
The binding behaviors and thermodynamic origins of p-sulfonatocalix[4]arene (C4AS) and p-sulfonatocalix[5]arene (C5AS) with methyl viologen (MV2+) have been investigated by the methods of isothermal titration calorimetry, NMR, and cyclic voltammetry, showing that the binding abilities of C4AS and C5AS and their host selectivity are dramatically pH-controlled, which is closely discussed from the viewpoint of thermodynamics. Moreover, the radical form of MV+• can also be effectively included by C4AS and C5AS.
