    Abstract: The corona-like spikes or peplomers on the surface of the virion under electronic microscope are the most striking features of coronaviruses. The S (spike) protein is the largest structural protein, with 1,255 amino acids, in the viral genome. Its structure can be divided into three regions: a long N-terminal region in the exterior, a characteristic transmembrane (TM) region, and a short C-terminus in the interior of a virion. We detected fifteen substitutions of nucleotides by comparisons with the seventeen published SARS-CoV genome sequences, eight (53.3%) of which are non-synonymous mutations leading to amino acid alternations with predicted physiochemical changes. The possible antigenic determinants of the S protein are predicted, and the result is confirmed by ELISA (enzyme-linked immunosorbent assay) with synthesized peptides. Another profound finding is that three disulfide bonds are defined at the C-terminus with the N-terminus of the E (envelope) protein, based on the typical sequence and positions, thus establishing the structural connection with these two important structural proteins, if confirmed. Phylogenetic analysis reveals several conserved regions that might be potent drug targets.

    Abstract: Beijing has been one of the epicenters attacked most severely by the SARS-CoV (severe acute respiratory syndrome-associated coronavirus) since the first patient was diagnosed in one of the city’s hospitals. We now report complete genome sequences of the BJ Group, including four isolates (Isolates BJ01, BJ02, BJ03, and BJ04) of the SARS-CoV. It is remarkable that all members of the BJ Group share a common haplotype, consisting of seven loci that differentiate the group from other isolates published to date. Among 42 substitutions uniquely identified from the BJ group, 32 are non-synonymous changes at the amino acid level. Rooted phylogenetic trees, proposed on the basis of haplotypes and other sequence variations of SARS-CoV isolates from Canada, USA, Singapore, and China, gave rise to different paradigms but positioned the BJ Group, together with the newly discovered GD01 (GD-Ins29) in the same clade, followed by the H-U Group (from Hong Kong to USA) and the H-T Group (from Hong Kong to Toronto), leaving the SP Group (Singapore) more distant. This result appears to suggest a possible transmission path from Guangdong to Beijing/Hong Kong, then to other countries and regions.

    Abstract: In acute coronary syndrome (ACS) patients without advanced renal dysfunction [estimated glomerular filtration rate (eGFR) & lt; 30 mL/min/1.73 m2], early (within 24 h of admission) angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB) is the guideline-directed medical therapy. The clinical efficacy of early ACEI/ARB therapy among ACS patients with advanced renal dysfunction remains unclear. Methods and results Among 184 850 ACS patients hospitalized from July 2014 to December 2018 in the Chinese National Electronic Disease Surveillance System Platform (CNEDSSP) cohort and 113 650 ACS patients enrolled from November 2014 to December 2019 in the Improving Care for Cardiovascular Disease in China-ACS Project (CCC-ACS) cohort, we identified 3288 and 3916 ACS patients with admission eGFR & lt; 30 mL/min/1.73 m2 [2647 patients treated with ACEI/ARB (36.7%)], respectively. After 1:1 propensity score matching (PSM) in each cohort, Kaplan–Meier analysis showed that early ACEI/ARB use was associated with a 39% [hazard ratio (HR): 0.61, 95% confidence interval (95% CI): 0.45–0.82] and a 34% (HR: 0.66, 95% CI: 0.46–0.95) reduction in in-hospital mortality in CNEDSSP and CCC-ACS cohorts, respectively, which was consistent in multiple sensitivity analyses. A random effect meta-analysis of the two cohorts after PSM revealed a 32% reduction (risk ratio: 0.68, 95% CI: 0.55–0.84) in in-hospital mortality among ACEI/ARB users. Conclusions Based on two nationwide cohorts in China in contemporary practice, we demonstrated that ACEI/ARB therapy initiated within 24 h of admission is associated with a reduction in in-hospital mortality in ACS patients with advanced renal dysfunction. Clinical trial registration CCC-ACS project was registered at URL: https://www.clinicaltrials.gov. (Unique identifier: NCT02306616).

    Abstract: Large and long ears are regarded as symbols of wealth and health in East Asian culture, and people with lying ears often want their ears to be more exposed and prominent. Surgeries to correct lying ears have been documented. Objectives The aim of this study was to report the correction of lying ears and the aesthetic modification of helix and ear lobule with hyaluronic acid (HA) injections. Methods HA injections were performed at the auriculocephalic sulcus to increase the cranioauricular angle (CA) and correct lying ears. The injections at helix and lobule were case specific. The CA was measured and photographs were taken at baseline and at 1-, 3-, 6-, and 10-month follow-ups. Efficacy was assessed with the 5-point Global Aesthetic Improvement Scale (GAIS). Adverse events were recorded. Results Forty-six patients (92 ears) received HA injections and completed follow-ups. Instant correction outcomes were observed. Sixteen (34.8%) patients received 1 touch-up injection, the clinical efficacy of which persisted for 1 to 1.5 years. For over 90% of cases with touch-up treatment the GAIS was “very much improved” or “much improved” at all follow-ups. The GAIS for over 70% of cases without touch-up treatment was “very much improved” or “much improved” at 1-, 3-, and 6-month follow-ups. CA increased significantly compared with the baseline. Patients also reported “more V-shaped face shape” and “lifted jawline” effects. No serious adverse events occurred. Conclusions As an alternative technique to surgeries, HA filler injections at the auriculocephalic sulcus effectively corrected lying ears. This technique produced immediate, long-lasting, and aesthetically pleasing results. The side effects and downtime were minimal. Level of Evidence: 3

    Abstract: Lymphocyte trafficking via chemokine receptors such as C-C chemokine receptor 5 (CCR5) and CXCR3 plays a critical role in the pathogenesis of acute graft-versus-host disease (aGVHD). Our previous studies showed that the addition of CCR5 or CXCR3 antagonists could only slightly alleviate the development of aGVHD. Given the specificity of T lymphocytes bearing CXCR3 and CCR5, we investigated whether combined CCR5 and CXCR3 blockade could further attenuate murine aGVHD. A mouse model of aGVHD was established to assess the efficacy of CCR5 and/or CXCR3 blockade on the development of aGVHD. The distribution of lymphocytes was calculated by quantification of immunostaining cells. The immunomodulatory effect on T cells was assessed by evaluating T-cell proliferation, viability, and differentiation. Using the murine allogeneic hematopoietic stem cell transplantation model, we demonstrated that blockade of both CCR5 and CXCR3 could efficiently alleviate the development of aGVHD. Further investigation on the immune mechanisms for this prophylactic effect showed that more T cells were detained into secondary lymphoid organs (SLOs), which may lead to reduced infiltration of T cells into GVHD target organs. Our study also showed that T cells detained in SLOs dampened the activation, suppressed the polarization toward T helper type 1 (Th1) and T cytotoxic type 1 (Tc1) cells, and induced the production of Treg cells. These data suggest that concurrent blockade of CCR5 and CXCR3 attenuates murine aGVHD through modulating donor-derived T-cell distribution and function, and this might be applicable for aGVHD prophylaxis in clinical settings.

    Abstract: We aimed to describe the clinical and histopathologic features of Castleman disease (CD), particularly emphasizing its associations with paraneoplastic pemphigus (PNP) and prognosis. Methods We retrospectively enrolled 123 CD patients at our center. Clinical, pathologic, and laboratory data were reviewed. Results Fifty percent of the patients had PNP. Compared with those without PNP, patients with PNP-associated CD had more hyaline vascular (HV) variants (83.9% vs 57.4%), fewer mixed cellular variants (16.1% vs 24.6%), and no plasmacytic variants (0% vs 18.0%). Thirty-eight of 87 patients with the HV variant of CD (HV-CD) had stroma-rich (SR) features, and the incidence rate was higher in those with PNP-associated CD than in those without PNP (48.4% vs 13.1%, P & lt; .001). The SR variant was associated with higher PNP-associated IgG titers than SR absence before surgery (median 1:160 vs 1:80, P = .019) or after surgery (median 1:160 vs 1:40, P = .013). The SR variant was also an unfavorable prognostic factor for CD survival in univariate analysis. The 3-year survival rates were 47.5% among those with PNP and 87.7% among those without PNP (P & lt; .001). Conclusions PNP is associated with specific subtypes of CD and affects survival. The SR variant of HV-CD positively correlates with the incidence of PNP.

    Abstract: We report a complete genomic sequence of rare isolates (minor genotype) of the SARS-CoV from SARS patients in Guangdong, China, where the first few cases emerged. The most striking discovery from the isolate is an extra 29-nucleotide sequence located at the nucleotide positions between 27,863 and 27,864 (referred to the complete sequence of BJ01) within an overlapped region composed of BGI-PUP5 (BGI-postulated uncharacterized protein 5) and BGI-PUP6 upstream of the N (nucleocapsid) protein. The discovery of this minor genotype, GD-Ins29, suggests a significant genetic event and differentiates it from the previously reported genotype, the dominant form among all sequenced SARS-CoV isolates. A 17-nt segment of this extra sequence is identical to a segment of the same size in two human mRNA sequences that may interfere with viral genome replication and transcription in the cytosol of the infected cells. It provides a new avenue for the exploration of the virus-host interaction in viral evolution, host pathogenesis, and vaccine development.

    Abstract: The predictive value of white blood cells in triple-vessel coronary artery disease (TVD) remains unclear. This study aimed to examine the relationship between WBC counts and long-term prognosis of TVD. Methods A total of 8943 consecutive patients with triple-vessel coronary artery disease were enrolled from April 2004 to February 2011. The primary endpoint was all-cause death and the secondary endpoints were major adverse cardiovascular and cerebrovascular events (MACCEs; a composite of all-cause death, myocardial infarction or stroke). Results After a median of 7.5 years of follow-up, 7678 patients were included in the final analysis. Multivariable analysis showed that the white blood cell count was an independent predictor of death (hazard ratio: 1.04, p  〈  0.01) and MACCE (hazard ratio: 1.03, p = 0.02). In white blood cell differential analysis, increased monocytes (hazard ratio: 1.93, p = 0.001) and eosinophils (hazard ratio: 1.82, p  〈  0.01), and decreased lymphocytes (hazard ratio: 0.89, p = 0.02) were independent predictors of death. Increased monocytes (hazard ratio: 1.62, P = 0.002) and eosinophils (hazard ratio: 1.55, p  〈  0.01) were independent predictors of MACCE. A combination of monocyte, lymphocyte and eosinophil counts with the Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score improved the predictive value for mortality (area under the curve from 0.569 to 0.611; integrated discrimination improvement = 0.012; net reclassification improvement = 0.299) and improved slightly with SYNTAX score II (all p  〈  0.05). Conclusion Total and differential white blood cell counts are independent prognostic factors of long-term mortality and MACCE in triple-vessel coronary artery disease. A combination of monocyte, lymphocyte and eosinophil counts improved the predictive value for mortality with the SYNTAX score, and improved it slightly with SYNTAX score II.
