A map of direct SARS-CoV-2 protein interactions implicates specific human host processes

Key steps in viral propagation, immune suppression, and pathology are mediated by direct, binary, physical interactions between viral and host proteins. To understand the biology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, we generated an unbiased systematic map of binary interactions between viral and host proteins, complementing previous co-complex association maps by conveying more direct mechanistic understanding and potentially enabling targeted disruption of direct interactions. To this end, we deployed two parallel strategies, identifying 205 virus-host and 27 intraviral binary interactions amongst 171 host and 19 viral proteins, and confirming high quality of these interactions via a calibrated orthogonal assay. Host proteins interacting with SARS-CoV-2 proteins are enriched in various cellular processes, including immune signaling and inflammation, protein ubiquitination, and membrane trafficking. Specific subnetworks provide new hypotheses related to viral modulation of host protein homeostasis and T-cell regulation. The binary virus-host protein interactions we identified can now be prioritized as targets for therapeutic intervention. More generally, we provide a resource of systematic maps describing which SARS-CoV-2 and human proteins interact directly.

Decrease of respiratory diseases in one social children welfare institute in Shanxi Province during COVID-19.

BACKGROUND: To assess the impact of disinfection measures on the incidence of common diseases in children welfare institute during the epidemic of Corona Virus Disease 2019 (COVID-19), and provide a basis for the daily disinfection management of children welfare institute. METHODS: This study surveyed and analyzed common diseases among children under the age of 14 in one social children welfare institute in Shanxi Province from January to May in 2018-2020 by the year-on-year method. RESULTS: The prevalence rate of respiratory diseases in 2020 was a significantly negative growth compared with 2018 and 2019. There was no obvious pattern of changes in digestive diseases group. CONCLUSION: In view of the above anti-epidemic measures, it indicates that the children gathering institutions should strengthen effective personal protection and public health management to reduce infectious disease among children.

Pathogenesis and prevention strategy of hepatocellular carcinoma in acute intermittent porphyria / 临床肝胆病杂志

With the development of genetics and molecular biology, the research on acute intermittent porphyria (AIP) has been gradually deepened, and its complication hepatocellular carcinoma (HCC) has attracted more and more attention. This article mainly summarizes the research advances in the pathogenesis and prevention of HCC in AIP. The pathogenesis of AIP with HCC is associated with oxidative stress, p53 mutation, downregulation of Bcl-2, increase in inflammatory cytokines, and iron overload, and its prevention strategies include the use of statins, strict management, liver transplantation, gene therapy, and enzyme replacement therapy. This article reviews the latest advances in the pathogenesis and prevention of AIP with HCC.

Diagnosis and treatment strategies for inflammatory bowel disease with concomitant biliary diseases / 临床肝胆病杂志

Inflammatory bowel disease (IBD) is a series of non-specific chronic inflammatory diseases, including ulcerative colitis and Crohn’s disease. Besides gastrointestinal symptoms, IBD patients often have extraintestinal symptoms which may involve various systems such as the skeleton and muscle, skin, eyes, liver and gallbladder, pancreas, nerves, urogenital system, lungs, heart, and blood. Biliary diseases are extraintestinal manifestations of IBD and mainly include primary sclerosing cholangitis, IgG4-associated sclerosing cholangitis, primary biliary cirrhosis, and cholelithiasis. Biliary diseases may manifest as transient abnormal liver function in asymptomatic patients and even life-threatening liver failure, and different biliary diseases may have different treatment methods and prognoses and thus require careful differential diagnosis. This article reviews biliary diseases in IBD patients, in order to help clinicians get familiar with the clinical manifestations and diagnosis and treatment strategies for biliary diseases in IBD patients.

Comparison of the Hospital-Acquired Clostridium difficile Infection Risk of Using Proton Pump Inhibitors versus Histamine-2 Receptor Antagonists for Prophylaxis and Treatment of Stress Ulcers: A Systematic Review and Meta-Analysis

BACKGROUND/AIMS: Although proton pump inhibitors (PPIs) have been widely used for the prevention and treatment of stress gastric ulcers in hospital settings, there are concerns that PPIs increase the risk of Clostridium difficile infection (CDI). However, little is known about the risk of CDI following PPI and histamine-2 receptor antagonist (H2RA) use. We evaluated the comparative hospital-acquired CDI occurrence risk associated with the concurrent use of PPIs versus H2RAs. METHODS: A systematic search of PubMed, MEDLINE/Ovid, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, and Google Scholar through August 19, 2016, identified 12 studies that reported the hospital-acquired CDI occurrence following H2RA and PPI use for the prevention and treatment of stress gastric ulcers. Random-effects pooled odds ratios and 95% confidence intervals were estimated. Heterogeneity was measured using I², and a meta-regression analysis was conducted. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to assess the overall quality of the evidence. RESULTS: A total of 74,132 patients from 12 observational studies were analyzed. Compared to H2RAs, PPIs increased the risk of CDI by 38.6% (pooled odds ratio, 1.386; 95% confidence interval, 1.152 to 1.668; p=0.001; I²=42.81%). Subgroup analyses of the purpose of study medication use, study site, and study design confirmed the consistency of a greater CDI risk with PPIs than with H2RAs. The overall quality of evidence was rated as low. CONCLUSIONS: The use of PPIs for both the prevention and treatment of stress ulcers was associated with a 38.6% increased risk of hospital-acquired CDI occurrence compared to H2RA use.

The prevalence of hyperuricemia in China: a meta-analysis.

BACKGROUND: The prevalence of hyperuricemia varied in different populations and it appeared to be increasing in the past decades. Recent studies suggest that hyperuricemia is an independent risk factor for cardiovascular disease. However, there has not yet been a systematic analysis of the prevalence of hyperuricemia in China. METHODS: Epidemiological investigations on hyperuricemia in China published in journals were identified manually and on-line by using CBMDISC, Chongqing VIP database and CNKI database. Those Reported in English journals were identified using MEDLINE database. Selected studies had to describe an original study defined by strict screening and diagnostic criteria. The fixed effects model or random effects model was employed according to statistical test for homogeneity. RESULTS: Fifty-nine studies were selected, the statistical information of which was collected for systematic analysis. The results showed that the pooled prevalence of hyperuricemia in male was 21.6% (95%CI: 18.9%-24.6%), but it was only 8.6% (95%CI: 8.2%-10.2%) in female. It was found that thirty years was the risk point age in male and it was fifty years in female. CONCLUSIONS: The prevalence of hyperuricemia is different as the period of age and it increases after 30 years in male and 50 in female. Interventions are necessary to change the risk factors before the key age which is 30 years in male and 50 in female.
