    Abstract: To combat the coronavirus disease 2019 (COVID-19) pandemic, nonpharmaceutical interventions (NPIs) were implemented worldwide, which impacted a broad spectrum of acute respiratory infections (ARIs). Methods Etiologically diagnostic data from 142 559 cases with ARIs, who were tested for 8 viral pathogens (influenza virus [IFV], respiratory syncytial virus [RSV] , human parainfluenza virus [HPIV], human adenovirus [HAdV] , human metapneumovirus [HMPV], human coronavirus [HCoV] , human bocavirus [HBoV], and human rhinovirus [HRV] ) between 2012 and 2021, were analyzed to assess the changes in respiratory infections in China during the first COVID-19 pandemic year compared with pre-pandemic years. Results Test-positive rates of all respiratory viruses decreased during 2020, compared to the average levels during 2012–2019, with changes ranging from −17.2% for RSV to −87.6% for IFV. Sharp decreases mostly occurred between February and August when massive NPIs remained active, although HRV rebounded to the historical level during the summer. While IFV and HMPV were consistently suppressed year-round, RSV, HPIV, HCoV, HRV, and HBoV resurged and went beyond historical levels during September 2020–January 2021, after NPIs were largely relaxed and schools reopened. Resurgence was more prominent among children & lt;18 years and in northern China. These observations remain valid after accounting for seasonality and long-term trend of each virus. Conclusions Activities of respiratory viral infections were reduced substantially in the early phases of the COVID-19 pandemic, and massive NPIs were likely the main driver. Lifting of NPIs can lead to resurgence of viral infections, particularly in children.

    Abstract: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel β-coronavirus, causes severe pneumonia and has spread throughout the globe rapidly. The disease associated with SARS-CoV-2 infection is named coronavirus disease 2019 (COVID-19). To date, real-time reverse-transcription polymerase chain reaction (RT-PCR) is the only test able to confirm this infection. However, the accuracy of RT-PCR depends on several factors; variations in these factors might significantly lower the sensitivity of detection. Methods In this study, we developed a peptide-based luminescent immunoassay that detected immunoglobulin (Ig)G and IgM. The assay cutoff value was determined by evaluating the sera from healthy and infected patients for pathogens other than SARS-CoV-2. Results To evaluate assay performance, we detected IgG and IgM in the sera from confirmed patients. The positive rate of IgG and IgM was 71.4% and 57.2%, respectively. Conclusions Therefore, combining our immunoassay with real-time RT-PCR might enhance the diagnostic accuracy of COVID-19.

    Abstract: ETS family transcription factors are evolutionarily conserved downstream effectors of Ras/MAPK signaling with critical roles in development and cancer. In Drosophila, the ETS repressor Yan regulates cell proliferation and differentiation in a variety of tissues; however, the mechanisms of Yan-mediated repression are not well understood and only a few direct target genes have been identified. Yan, like its human ortholog TEL1, self-associates through an N-terminal sterile α-motif (SAM), leading to speculation that Yan/TEL1 polymers may spread along chromatin to form large repressive domains. To test this hypothesis, we created a monomeric form of Yan by recombineering a point mutation that blocks SAM-mediated self-association into the yan genomic locus and compared its genome-wide chromatin occupancy profile to that of endogenous wild-type Yan. Consistent with the spreading model predictions, wild-type Yan-bound regions span multiple kilobases. Extended occupancy patterns appear most prominent at genes encoding crucial developmental regulators and signaling molecules and are highly conserved between Drosophila melanogaster and D. virilis, suggesting functional relevance. Surprisingly, although occupancy is reduced, the Yan monomer still makes extensive multikilobase contacts with chromatin, with an overall pattern similar to that of wild-type Yan. Despite its near-normal chromatin recruitment, the repressive function of the Yan monomer is significantly impaired, as evidenced by elevated target gene expression and failure to rescue a yan null mutation. Together our data argue that SAM-mediated polymerization contributes to the functional output of the active Yan repressive complexes that assemble across extended stretches of chromatin, but does not directly mediate recruitment to DNA or chromatin spreading.

    Abstract: A persistent cardiac T-cell response initiated by myocardial infarction is linked to subsequent adverse ventricular remodelling and progression of heart failure. No data exist on T-cell receptor (TCR) repertoire changes in combination with phenotypic characterization of T cells in ischaemic failing human hearts. Methods and results Analysis of TCR repertoire with high-throughput sequencing revealed that compared with T cells in control hearts, those in ischaemic failing hearts showed a clonally expanded TCR repertoire but similar usage patterns of TRBV-J rearrangements and V gene segments; compared with T cells in peripheral blood, those in ischaemic failing hearts exhibited a restricted and clonally expanded TCR repertoire and different usage patterns of TRBV-J rearrangements and V gene segments, suggesting the occurrence of tissue-specific T-cell expansion in ischaemic failing hearts. Consistently, TCR clonotype sharing was prominent in ischaemic failing hearts, especially in hearts of patients who shared human leucocyte antigen (HLA) alleles. Furthermore, ischaemia heart failure (IHF) heart-associated clonotypes were more frequent in peripheral blood of IHF patients than in that of controls. Heart-infiltrating T cells displayed memory- and effector-like characteristics. Th1 cells were the predominant phenotype among CD4  + T cells; CD8  + T cells were equally as abundant as CD4  + T cells and produced high levels of interferon-γ, granzyme B, and perforin. Conclusion We provide novel evidence for a tissue-specific T-cell response predominated by Th1 cells and cytotoxic CD8  + T cells in ischaemic failing human hearts that may contribute to the progression of heart failure.

    Abstract: Coronavirus disease 2019 (COVID-19) is a global pandemic with no licensed vaccine or specific antiviral agents for therapy. Little is known about the longitudinal dynamics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)–specific neutralizing antibodies (NAbs) in patients with COVID-19. Methods Blood samples (n = 173) were collected from 30 patients with COVID-19 over a 3-month period after symptom onset and analyzed for SARS-CoV-2–specific NAbs using the lentiviral pseudotype assay, coincident with the levels of IgG and proinflammatory cytokines. Results SARS-CoV-2–specific NAb titers were low for the first 7–10 days after symptom onset and increased after 2–3 weeks. The median peak time for NAbs was 33 days (interquartile range [IQR], 24–59 days) after symptom onset. NAb titers in 93.3% (28/30) of the patients declined gradually over the 3-month study period, with a median decrease of 34.8% (IQR, 19.6–42.4%). NAb titers increased over time in parallel with the rise in immunoglobulin G (IgG) antibody levels, correlating well at week 3 (r = 0.41, P & lt; .05). The NAb titers also demonstrated a significant positive correlation with levels of plasma proinflammatory cytokines, including stem cell factor (SCF), TNF-related apoptosis-inducing ligand (TRAIL), and macrophage colony-stimulating factor (M-CSF). Conclusions These data provide useful information regarding dynamic changes in NAbs in patients with COVID-19 during the acute and convalescent phases.

    Abstract: Whether photosynthesis has improved with increasing yield in major crops remains controversial. Research in this area has often neglected to account for differences in light intensity experienced by cultivars released in different years. Light intensity is expected to be positively associated with photosynthetic capacity and the resistance of the photosynthetic apparatus to high light but negatively associated with light-utilization efficiency under low light. Here, we analyzed the light environment, photosynthetic activity, and protein components of leaves of 26 winter wheat cultivars released during the past 60 years in China. Over time, light levels on flag leaves significantly decreased due to architectural changes, but photosynthetic rates under high or low light and the resistance of the photosynthetic apparatus to high light remained steady, contrary to expectations. We propose that the difference between the actual and expected trends is due to breeding. Specifically, breeding has optimized photosynthetic performance under high light rather than low light. Moreover, breeding selectivity altered the stoichiometry of several proteins related to dynamic photosynthesis, canopy light distribution, and photoprotection. These results indicate that breeding has significantly altered the photosynthetic mechanism in wheat and its response to the light environment. These changes likely have helped increase wheat yields.

    Abstract: Chronic kidney disease is a common disease. Most chronic kidney diseases evolve from primary glomerulonephritis. Proteinuria is an independent risk factor for the progression of chronic kidney disease. The general consensus is that therapy administered to decrease proteinuria should include steroids and/or immunosuppressants, angiotensin-converting enzyme inhibitors, and angiotensin II receptor blockers. However, the side effects of, and adverse reactions to, these agents reduce the benefits to patients. Therefore, additional effective drugs to decrease proteinuria are urgently needed. Shenyankangfu tablets (SYKFT) have been a widely applied Chinese patent medicine for many years to decrease proteinuria. However, there is a lack of research-derived data regarding the clinical use. Therefore, we designed the present trial to compare the efficacy and safety of SYKFT versus losartan potassium for control of proteinuria in patients with primary glomerulonephritis. Method This was a multicenter, prospective, double-blind, double-dummy, randomized controlled clinical trial. Primary glomerulonephritis patients aged 18 to 70 years, blood pressure ≤140/90 mmHg, estimated glomerular filtration rate ≥45 mL/min/1.73 m2, 24-hour proteinuria level of 0.5 to 3.0 g, were recruited in 41 hospitals across 19 provinces in China and were randomly divided into the following groups at a 1:1:1:1:1 ratio: SYKFT group, losartan potassium 50 mg group, losartan potassium 100 mg group, SYKFT plus losartan potassium 50 mg group, and SYKFT plus losartan potassium 100 mg group. All groups were followed up for 48 weeks; follow-up visits were performed, at weeks 0, 4, 8, 12, 24, 36, and 48. The primary efficacy outcome was the post-treatment change in the 24-hour proteinuria level, and the secondary efficacy outcomes was the post-treatment changes in the serum creatinine level, estimated glomerular filtration rate (eGFR), traditional Chinese medicine (TCM) syndrome score, and serum albumin level. The protocol was approved by the Ethics Committee of each participating center. This trial was registered at the clinicaltrials.gov (NCT02063100). Results A total of 720 participants were enrolled and 673 patients were included in the analysis. The difference in the urine protein reduction among different groups was statistically significant (Z=20.084, P=0.001). The urine protein reduction in the SYKFT group [-150.000 (-692.500, 153.000) mg/d] , more than that in the losartan potassium 50mg alone group [-80.000 (-420.000, 295.250) mg/d, Z=-2.015, P=0.044], was not less than that in the losartan potassium 100mg group [-260.000 (-623.900, 84.000) mg/d, Z=-0.339, P=0.734] . The urine protein reduction in the SYKFT plus losartan potassium 50mg group [-269.150 (-755.000, 159.085) mg/d] was more than that in the losartan potassium 50mg alone group [Z=-2.582, P=0.010] . The urine protein reduction in the SYKFT plus losartan potassium 100mg group [-388.000 (-743.500, -10.000) mg/d] was more than that in the losartan potassium 100mg alone group [Z=-1.999, P=0.046] . The changes in serum creatinine, eGFR, and serum albumin from the baseline were not statistically significant among different groups (P all & gt;0.05). The change in TCM syndrome scores between the patients who took SYKFT and who did not take SYKFT was statistically significant (P=0.003). Conclusion SYKFT can decrease the proteinuria of primary glomerulonephritis patients with minor- to moderate-range proteinuria. SYKFT plus losartan potassium therapy can decrease proteinuria to a relatively large extent compared with losartan potassium therapy alone. And SYKFT can also improve the TCM syndrome scores of the patients.
