Hepatitis B virus middle surface antigen loss promotes clinical variant persistence in mouse models

Junyu Lin, Jing Li, Peilin Xie, Yue Han, Demin Yu, Jia Chen & Xinxin Zhang
Hepatitis B virus (HBV) middle surface antigen (MHBs) mutation or deletion occurs in patients with chronic HBV infection. However, the functional role of MHBs in HBV infection is still an enigma. Here, we reported that 7.33% (11/150) isolates of CHB patients had MHBs start codon mutations compared with 0.00% (0/146) in acute hepatitis B (AHB) patients. Interestingly, MHBs loss accounted for 11.88% (126/1061) isolates from NCBI GenBank, compared with 0.09% (1/1061) and 0.00% (0/1061) for...

Glycosylation on envelope glycoprotein of duck Tembusu virus affects virus replication in vitro and contributes to the neurovirulence and pathogenicity in vivo

Dejian Liu, Xuyao Xiao, Peng Zhou, Huijun Zheng, Yaqian Li, Hui Jin, Anan Jongkaewwattana & Rui Luo
Duck Tembusu virus (DTMUV), an emergent flavivirus, causes domestic waterfowls to suffer from severe egg-drop syndrome and fatal encephalitis, greatly threatens duck production globally. Like other mosquito-borne flaviviruses, the envelope (E) protein of all DTMUV strains was N-glycosylated at the amino acid position 154. Thus far, the biological roles of DTMUV E glycosylation have remained largely unexplored. Herein, we demonstrated the key roles of E glycosylation in the replication and pathogenicity of DTMUV in ducks...

Four new resorcinol derivatives with neuroprotective activities from Xylaria nigripes

Lan-Qing Li, Jing Li, Hong-Ping Long, Ji-Kai Liu & Xian Wang
Four new resorcinol derivatives, namely (−)/(+)-xylarinig A (1), as well as xylarinigs B (2) and C (3), were isolated from the ethyl acetate extracts of the solid fermentation of Xylaria nigripes. Their structures were established by comprehensive spectroscopic analysis combined with electronic circular dichroism (ECD) calculations. Compound 1 is an optical mixture, and was resoluted into optical pure enatiomers (+)-1 and (−)-1 by chiral HPLC. The neuroprotective effects of 1–3 against the damage of PC12...

Discovery of novel serum metabolic biomarkers in patients with polycystic ovarian syndrome and premature ovarian failure

Jiying Chen, Qinger Zhou, Yonggang Zhang, Wenqing Tan, Hanchao Gao, Liying Zhou, Shuixiu Xiao, Jinhua Gao, Jing Li & Zhiying Zhu
Several widely recognized metabolites play a role in regulating the pathophysiological processes of various disorders. Nonetheless, the lack of effective biomarkers for the early diagnosis of polycystic ovarian syndrome (PCOS) and premature ovarian failure (POF) has led to the discovery of serum-based metabolic biomarkers for these disorders. We aimed to identify various differentially expressed metabolites (DEMs) through serum-based metabolic profiling in patients with PCOS and POF and in healthy individuals by using liquid chromatography–mass spectrometry...

High Child-Pugh and CRUB65 scores predict mortality of decompensated cirrhosis patients with COVID-19: A 23-center, retrospective study

Yong Xiao, Dongwen Wu, Xiao Shi, Shuzhong Liu, Xudong Hu, Chenliang Zhou, Xia Tian, Huimin Liu, Hui Long, Zhihong Li, Ji Wang, Tao Tan, Ying Xu, Bitao Chen, Ting Liu, Heng Zhang, Shihua Zheng, Shunlin Hu, Jun Song, Jie Tang, Jichun Song, Zhengwei Cheng, Weitian Xu, Yongxiang Shen, Wenhu Yu … & Mingkai Chen
Background: COVID-19 has rapidly become a major health emergency worldwide. The characteristic, outcome, and risk factor of COVID-19 in patients with decompensated cirrhosis remain unclear. Methods: Medical records were collected from 23 Chinese hospitals. Patients with decompensated cirrhosis and age- and sex-matched non-liver disease patients were enrolled with 1:4 ratio using stratified sampling. Results: There were more comorbidities with higher Chalson Complication Index (p < 0.001), higher proportion of patients having gastrointestinal bleeding, jaundice, ascites,...

Aspirin relieves the calcification of aortic smooth muscle cells by enhancing the heat shock response

Quanquan Shen, Qian Chen, Yang Liu, Xiang Xue, Xiaogang Shen, Qiang He, Guokun Wang & Fei Han
Vascular calcification is a major complication of chronic renal failure, which has been identified as an active process partly driven by osteogenic transition of vascular smooth muscle cells (VSMCs). Aspirin could prevent cardiomyocyte damage by inducing heat shock response. This study investigates the effect of aspirin on alleviating VSMC calcification. An in vitro VSMC calcification model was established by 10-day calcification induction in osteogenic medium. VSMCs were grouped as following: control group (normal medium), calcified...

In this study, a novel intelligent nanoplatform to integrate multiple imaging and therapeutic functions for targeted cancer theranostics. The nanoplatform, DOX@Gd-MFe3O4 NPs, was constructed Gd-doped mesoporous Fe3O4 nanoparticles following with the doxorubicin (DOX) loading in the mesopores of the NPs. The DOX@Gd-MFe3O4 NPs exhibited good properties in colloidal dispersity, photothermal conversion, NIR triggered drug release, and high T1/T2 relaxicity rate (r1=9.64 mM−1s−1, r2= 177.71 mM−1s−1). Benefiting from the high MR contrast, DOX@Gd-MFe3O4 NPs enabled simultaneous...
