Since the outbreak of coronavirus disease 2019 (COVID-19) in Wuhan, China, it has rapidly spread across many other countries. While the majority of patients were considered mild, critically ill patients involving respiratory failure and multiple organ dysfunction syndrome are not uncommon, which could result death. We hypothesized that cytokine storm is associated with severe outcome. We enrolled 102 COVID-19 patients who were admitted to Renmin Hospital (Wuhan, China). All patients were classified into moderate, severe...

Yuchang Li, Jing Li, Ying Zhang, Lizhong Dai, Lin Li, Juan Liu, Sen Zhang, Xiaoyan Wu, Yi Hu, Chengfeng Qin, Tao Jiang & Xiaoping Kang
In December 2019, Wuhan, China suffered a serious outbreak of a novel coronavirus infectious disease (COVID) caused by novel severe acute respiratory syndrome-related coronavirus (SARS-CoV 2). To quickly identify the pathogen, we designed and screened primer sets, and established a sensitive and specific qRT-PCR assay for SARS-CoV 2; the lower limit of detection (LOD) was 15 (95% CI: 9.8–21) copies per reaction. We combined this qRT-PCR assay with an automatic integration system for nucleic acid...

Co-existence of a novel plasmid-mediated efflux pump with colistin resistance gene mcr in one plasmid confers transferable multidrug resistance in Klebsiella pneumoniae

Shijun Sun, Hua Gao, Yudong Liu, Longyang Jin, Ruobing Wang, Xiaojuan Wang, Qi Wang, Yuyao Yin, Yawei Zhang & Hui Wang
Tigecycline is considered one of the last-resort antimicrobials for carbapenem-resistant K. pneumoniae. Plasmid-mediated tigecycline resistance remains largely unclear. Here, by utilizing whole genome sequencing, we report a plasmid-mediated tigecycline resistance mechanism, a 6,489 bp Resistance-nodulation-division family (RND) efflux pump (tmexCD1-toprJ1 pump), that confers transferable tigecycline resistance in K pneumoniae isolated from patients and chickens. In addition, we identified high prevalence of the plasmids co-harbouring both tmexCD1-toprJ1 pump and mcr (tmexCD1-mcr co-harbouring plasmid) from human in...

Replacing the 238th aspartic acid with an arginine impaired the oligomerization activity and inflammation-inducing property of pyolysin

Wenlong Zhang, Haili Wang, Bing Wang, Yue Zhang, Yunhao Hu, Bo Ma & Junwei Wang
Trueperella pyogenes (T. pyogenes) is an important opportunistic pathogen. Pyolysin (PLO) importantly contributes to the pathogenicity of T. pyogenes. However, the relationship between the structure and function and the virulence of PLO is not well documented. In the current study, recombinant PLO (rPLO) and three rPLO mutants were prepared. rPLO D238R, a mutant with the 238th aspartic acid replaced with an arginine, showed impairment in oligomerization activity on cholesterol-containing liposome and pore-forming activity on sheep...

Low intratumor heterogeneity correlates with increased response to PD-1 blockade in renal cell carcinoma

Xia Ran, Jinyuan Xiao, Yi Zhang, Huajing Teng, Fang Cheng, Huiqian Chen, Kaifan Zhang & Zhongsheng Sun
Background:Intratumor heterogeneity (ITH) has been shown to be inversely associated with immune infiltration in several cancers including clear cell renal cell carcinoma (ccRCC), but it remains unclear whether ITH is associated with response to immunotherapy (e.g. PD-1 blockade) in ccRCC.Methods:We quantified ITH using mutant-allele tumor heterogeneity, investigated the association of ITH with immune parameters in patients with ccRCC (n = 336) as well as those with papillary RCC (pRCC, n = 280) from The Cancer...

MicroRNA-146a-5p enhances T helper 17 cell differentiation via decreasing a disintegrin and metalloprotease 17 level in primary sjögren’s syndrome

Xiaoyan Wang, Shaojun Xin, Youqing Wang, Duo Ju, Quan Wu, Ye Qiu, Xuemin Niu, Wei Liu, Jianyou Li & Pengtian Ji
In clinical practice, we found that microRNA (miR)-146a-5p is significantly up-regulated in peripheral blood mononuclear cells (PBMCs) of primary sjögren’s syndrome (pSS) patients. In vitro experiments confirmed that miR-146a-5p promotes T helper 17 (Th17) cell differentiation, but the specific mechanism is still unknown. To solve this problem, 20 pSS patients and 20 healthy subjects were enrolled in this study and PBMCs were isolated from their blood. The expression of the membrane IL-23 R (mIL-23 R)...

Study on influencing factors of Pickering emulsion stabilized by modified montmorillonite and fatty alcohol polyoxyethylene ether

Qian Chen, Zeyu Yang, Xiumei Tai, Yanyun Bai & Guoyong Wang
Pickering emulsion is widely used in food, drug administration, and cosmetics. In practical applications, surfactants are often co-present with particles, so it is particularly critical to study particle-surfactant interactions. Pickering emulsions were prepared using stearyltrimethylammoniumchloride organic montmorillonite (STAC/MMT) and fatty alcohol polyoxyethylene ether (AEO-3) as stabilizers. Effects of AEO-3 content, STAC/MMT content, oil-water ratio, emulsification temperature, emulsification time on emulsion stability were systematically revealed by studying the particle size distribution and phase volume of the...

Preeclampsia (PE) is a disorder that occurs during the pregnancy and could affect the maternal and perinatal mortality as well as morbidity. The aim of our study is to investigate the associations between the hypertension susceptibility genes ITGA9, MOV10 and CACNB2 with PE in Chinese Han population. A case–control study including 178 PE patients and 202 healthy controls was conducted to assess the associations between three loci (ITGA9 rs155524, MOV10 rs2932538 and CACNB2 rs4373814) and...

Homeobox A5 activates p53 pathway to inhibit proliferation and promote apoptosis of adrenocortical carcinoma cells by inducing Aldo-Keto reductase family 1 member B10 expression

Danyan Chen, Zhaonan Shen, Xi Cheng, Qi Wang, Junlin Zhou, Fang Ren, Yue Sun, Hongman Wang & Rongxi Huang
Aldo-Keto Reductase Family 1 Member B10 (AKR1B10) and Homeobox A5 (HOXA5) are both down-regulated in adrenocortical carcinoma (ACC), and HOXA5 is predicted to bind to the promoter of AKR1B10. We aimed to investigate whether HOXA5 could bind to AKR1B10 to regulate ACC cells proliferation and apoptosis. The expression of AKR1B10 and HOXA5 in ACC patients and the relationship of their expression between ACC prognosis were evaluated by searching database. Then, NCI-H295R cells were overexpressed to...

Circulating microRNA profile unveils mechanisms of action of acitretin for psoriasis vulgaris

Lin Chen, Jie Li, Ying Yao, Shanlong Wang, Shuangjin Zheng, Xinggang Ju & Bin Zhang
Psoriasis vulgaris is a common chronic and recurrent inflammatory skin disease. In clinical practice, acitretin is the first-line treatment drug for psoriasis vulgaris. MicroRNAs (miRNAs) play a vital role in the initiation and development of psoriasis vulgaris. However few studies focused on the mechanisms of acitretin in the treatment of psoriasis vulgaris from the perspective of miRNAs. Here, the expression profiles of circulating miRNAs in the plasma of 12 patients with psoriasis vulgaris before and...

Shizhen Lei & Yi Zhang
Primary Sjögren’ s syndrome (pSS) is a relatively common autoimmune disease, which mainly involves the exocrine glands, causing dry eye, dryness of mouth, fatigue and pain in the joints, thus severely affecting the normal lives of patients. B cell populations are considered to play an important role in their pathogenesis and pSS patients are generally characterized by exhibiting biological signs of B cell activation. Moreover, another important characterized change in the peripheral blood of pSS...

Vestigial-like (Vgll) genes are widespread in vertebrates and play an important role in muscle development. In this study, we used bioinformatics methods to systematically identify the chicken VGLL family in the whole genome and investigated its evolutionary history and gene structure features. Tissue expression spectra combined with real-time PCR data were used to analyze the organizational expression pattern of the genes. Based on the maximum likelihood method, a phylogenetic tree of the VGLL family was...

A novel fusion circular RNA F-circBA1 derived from the BCR-ABL fusion gene displayed an oncogenic role in chronic myeloid leukemia cells

Yuan Tan, Zhenglan Huang, Xin Wang, Hongdan Dai, Guoyun Jiang & Wenli Feng
The BCR-ABL fusion gene plays a crucial role in the leukemogenesis of chronic myeloid leukemia (CML). The BCR-ABL oncoprotein encoded by this fusion gene has been extensively studied. However, research on whether BCR-ABL also affects circular RNAs (circRNAs) is limited. This study aimed to explore the new fusion circRNAs produced by BCR-ABL and their role in CML cells. In this study, we identified a novel fusion circRNA, named F-circBA1, originating from BCR-ABL in K562 and...
