The psychometric properties of the quick inventory of depressive symptomatology-self-report (QIDS-SR) in patients with HBV-related liver disease
Background: Comorbid depression in Hepatitis B virus (HBV) is common. Developing accurate and time efficient tools to measure depressive symptoms in HBV is important for research and clinical practice in China.
Aims: This study tested the psychometric properties of the Chinese version of the 16-item Quick Inventory of Depressive Symptomatology (QIDS-SR) in HBV patients.
Methods: The study recruited 245 depressed patients with HBV and related liver disease. The severity of depressive symptoms was assessed with the Montgomery-Asberg Depression Rating Scale (MADRS) and the QIDS-SR.
Results: Internal consistency (Cronbach’s alpha) was 0.796 for QIDS-SR. The QIDS-SR total score was significantly correlated with the MADRS total score (r=0.698, p.
Conclusions: The QIDS-SR (Chinese version) has good psychometric properties in HBV patients and appears to be useful in assessing depression in clinical settings
Prevalence of internet addiction disorder in Chinese university students: A comprehensive meta-analysis of observational studies
Background and aims: Internet addiction disorder (IAD) is common in university students. A number of studies have examined the prevalence of IAD in Chinese university students, but the results have been inconsistent. This is a meta-analysis of the prevalence of IAD and its associated factors in Chinese university students.
Methods: Both English (PubMed, PsycINFO, and Embase) and Chinese (Wan Fang Database and Chinese National Knowledge Infrastructure) databases were systematically and independently searched from their inception until January 16, 2017.
Results: Altogether 70 studies covering 122,454 university students were included in the meta-analysis. Using the random-effects model, the pooled overall prevalence of IAD was 11.3% (95% CI: 10.1%–12.5%). When using the 8-item Young Diagnostic Questionnaire, the 10-item modified Young Diagnostic Questionnaire, the 20-item Internet Addiction Test, and the 26-item Chen Internet Addiction Scale, the pooled prevalence of IAD was 8.4% (95% CI: 6.7%–10.4%), 9.3% (95% CI: 7.6%–11.4%), 11.2% (95% CI: 8.8%–14.3%), and 14.0% (95% CI: 10.6%–18.4%), respectively. Subgroup analyses revealed that the pooled prevalence of IAD was significantly associated with the measurement instrument (Q = 9.41, p = .024). Male gender, higher grade, and urban abode were also significantly associated with IAD. The prevalence of IAD was also higher in eastern and central of China than in its northern and western regions (10.7% vs. 8.1%, Q = 4.90, p = .027).
Conclusions: IAD is common among Chinese university students. Appropriate strategies for the prevention and treatment of IAD in this population need greater attention

Creation of quantum correlations between two atoms in a dissipative environment from an initial vacuum state
We have investigated the effect of counter-rotating terms on the dynamics of
entanglement and quantum discord between two identical atoms interacting with a
lossy single mode cavity field for a system initially in a vacuum state. The
counter-rotating terms are found to lead to steady states in the long time
limit which can have high quantum discord, but have no entanglement. The effect
of cavity decay rate on this steady state quantum discord has been also
investigated, surprisingly, the increase in cavity decay rate is found to both
enhance and maximize the steady quantum discord for separable states.Comment: Effects of counter-rotating interaction terms on quantum discor
Human cardiac pericytes are susceptible to SARS-CoV-2 infection
COVID-19 is associated with serious cardiovascular complications, with incompletely understood mechanism(s). Pericytes have key functions in supporting endothelial cells and maintaining vascular integrity. We demonstrate that human cardiac pericytes are permissive to SARS-CoV-2 infection in organotypic slice and primary cell cultures. Viral entry into pericytes is mediated by endosomal proteases, and infection leads to up-regulation of inflammatory markers, vasoactive mediators, and nuclear factor kappa-B-dependent cell death. Furthermore, we present evidence of cardiac pericyte infection in COVID-19 myocarditis patients. These data demonstrate that human cardiac pericytes are susceptible to SARS-CoV-2 infection and suggest a role for pericyte infection in COVID-19
CatNorth: An Improved Gaia DR3 Quasar Candidate Catalog with Pan-STARRS1 and CatWISE
A complete and pure sample of quasars with accurate redshifts is crucial for
quasar studies and cosmology. In this paper, we present CatNorth, an improved
Gaia DR3 quasar candidate catalog with more than 1.5 million sources in the
3 sky built with data from Gaia, Pan-STARRS1, and CatWISE2020. The XGBoost
algorithm is used to reclassify the original Gaia DR3 quasar candidates as
stars, galaxies, and quasars. To construct training/validation datasets for the
classification, we carefully built two different master stellar samples in
addition to the spectroscopic galaxy and quasar samples. An ensemble
classification model is obtained by averaging two XGBoost classifiers trained
with different master stellar samples. Using a probability threshold of
in our ensemble classification model and an
additional cut on the logarithmic probability density of zero proper motion, we
retrieved 1,545,514 reliable quasar candidates from the parent Gaia DR3 quasar
candidate catalog. We provide photometric redshifts for all candidates with an
ensemble regression model. For a subset of 89,100 candidates, accurate
spectroscopic redshifts are estimated with the Convolutional Neural Network
from the Gaia BP/RP spectra. The CatNorth catalog has a high purity of > 90%
while maintaining high completeness, which is an ideal sample to understand the
quasar population and its statistical properties. The CatNorth catalog is used
as the main source of input catalog for the LAMOST phase III quasar survey,
which is expected to build a highly complete sample of bright quasars with .Comment: 24 pages, 13 figures, submitted to AAS journals. Table 4 (The
CatNorth quasar candidate catalog) is available at

Spread of Streptococcus suis Sequence Type 7, China
Streptococcus suis sequence type (ST) 7 has been spreading throughout China. To determine events associated with its emergence, we tested 114 isolates. In all 106 ST7 strains responsible for human outbreaks and sporadic infections, the tetracycline-resistance gene, tetM, was detected on the conjugative transposon Tn916. Horizontal transmission of tetM is suspected
