Abstract
PURPOSE This study aimed to identify a diagnostic panel of serum microRNAs (miRNAs) for the early detection of bladder cancer (BC). METHODS Serum samples were collected from 112 BC patients and 112 normal controls (NCs). A three-stage selection was conducted to identify differentially expressed miRNAs as candidates to construct the diagnostic panel. Further, to explore their potential roles in urothelial BC, bioinformatics analyses, including target genes prediction and functional annotation, were used. RESULTS Six downregulated miRNAs (miR-1-3p, miR-30a-5p, miR-100-5p, miR-125b-5p, miR-143-3p, and miR-200c-3p) and one upregulated, miR-182-5p, in BC patients' serum were detected compared to NCs and were selected to establish the diagnostic panel. Based on a backward stepwise logistic regression analysis, miR-125b-5p, miR-182-5p, and miR-200c-3p comprehended the diagnostic panel [area under the curve (AUC) = 0.959, sensitivity = 91.67%, specificity = 92.5%]. CONCLUSION The panel of three miRNAs had an excellent diagnostic capability, representing a potential non-invasive method for early BC detection.

Abstract
OBJECTIVE Tension stimulation is an important inducer of endplate cartilage degeneration, but the specific regulatory mechanism remains unclear. This study was the first to reveal the mechanism by which methyltransferase-like 3 (METTL3)-mediated N(6)-methyladenosine (m6A) modification affected the extracellular matrix anabolism by tension-induced endplate chondrocytes. METHOD We examined the differences in METTL3 expression and m6A methylation levels in human endplate chondrocytes and human cartilage endplate tissues under in vitro tension. The effect on endplate cartilage degeneration was evaluated by manipulating m6A methylation mediated by METTL3 in vivo and in vitro. The effect of METTL3-mediated m6A methylation on the stability of sex-determining region Y-box transcription factor 9 (SOX9) gene expression was determined experimentally. RESULTS METTL3 expression and m6A methylation levels were significantly increased in degenerative human endplate cartilage tissue. Similarly, tension stimulation inhibited the ability of human endplate chondrocytes to synthesize extracellular matrix, which was accompanied by an increase in METTL3-mediated m6A methylation. The ability of endplate chondrocytes to resist tension was significantly enhanced by inhibiting METTL3 expression and subsequently downregulating m6A methylation in vitro and in vivo, thereby reducing intervertebral disc degeneration. Furthermore, METTL3 mediated SOX9 RNA methylation and disrupted SOX9 mRNA stability, thereby inhibiting the gene expression of the downstream collagen type II alpha 1 chain. CONCLUSION Tension stimulation downregulated SOX9 expression through METTL3-mediated m6A methylation, thereby inhibiting the synthesis of extracellular matrix in endplate chondrocytes.

Abstract
Despite the attention currently given to the potential environmental benefits of large-scale forest planting, there is a shortage of clear observational evidence regarding the effects on river flows, and what there is has often been contradictory or inconclusive. This paper presents three independently conducted paired-catchment forestry studies covering 66 station-years of flow measurements in the UK and Ireland. In each case coniferous evergreen trees were removed from one catchment with minimal soil disturbance while the adjoining control catchment was left unchanged. Trees were removed from 20% - 90% of the three experimental basins. Following woodland removal there was an increase in dry weather baseflow at all sites. Baseflows increased by about 8% after tree removal from a quarter of the Hore basin and by 41% for the near-total cut at Howan. But the changes were more complex for peak flows. Tree harvesting increased the smallest and most frequent peak storm flows, indicating that afforestation would lead to the suppression of such events. This was however restricted to events well below the mean annual flood, indicating that the impact of forests upon the largest and most damaging floods is likely to be limited. Whilst a forest cover can be effective in mitigating small and frequent stormflows it should never be assumed to provide protection against major flood events.

Abstract
OBJECTIVES This study aimed to evaluate the socio-economic burden imposed on the Chinese healthcare system during the coronavirus disease 2019 (COVID-19) pandemic. STUDY DESIGN A cross-sectional study was used to investigate how COVID-19 impacted health and medical costs in China. Data were derived from a subdivision of the Centers for Disease control and Prevention of China. METHODS We prospectively collected information from the Centers for Disease Control and Prevention and the designated hospitals to determine the cost of public health care and hospitalisation due to COVID-19. We estimated the resource use and direct medical costs associated with public health. RESULTS The average costs, per case, for specimen collection and nucleic acid testing (NAT [specifically, polymerase chain reaction {PCR}]) in low-risk populations were $29.49 and $53.44, respectively; however, the average cost of NAT in high-risk populations was $297.94 per capita. The average costs per 1000 population for epidemiological surveys, disinfectant, health education and centralised isolation were $49.54, $247.01, $90.22 and $543.72, respectively. A single hospitalisation for COVID-19 in China cost a median of $2158.06 ($1961.13-$2325.65) in direct medical costs incurred only during hospitalisation, whereas the total costs associated with hospitalisation of patients with COVID-19 were estimated to have reached nearly $373.20 million in China as of 20, May, 2020. The cost of public health care associated with COVID-19 as of 20, May, 2020 ($6.83 billion) was 18.31 times that of hospitalisation. CONCLUSIONS This study highlights the magnitude of resources needed to treat patients with COVID-19 and control the COVID-19 pandemic. Public health measures implemented by the Chinese government have been valuable in reducing the infection rate and may be cost-effective ways to control emerging infectious diseases.

Abstract
Background: Short peptide hydrogel was reported as a possible adjuvant for vaccines. In order to evaluate whether the Tetra-Peptide Hydrogel can be a promising adjuvant for an H7N9 vaccine against the highly pathogenic H7N9 virus, we conducted this study. Methods: Tetra-Peptide Hydrogels (D and L conformations) were prepared by a self-assembly system using a Naproxen acid modified tetra peptide of GFFY (Npx-GFFY). Mice received two immunizations with the D-Tetra-Peptide Hydrogel adjuvant vaccine, the L-Tetra-Peptide Hydrogel adjuvant vaccine, or the split vaccine. Fourteen days following the second dose, the mice were challenged with the highly pathogenic A/Guangdong/GZ8H002/2017(H7N9) virus. The mice were observed for signs of illness, weight loss, pathological alterations of the lung tissues and immune responses in the following 2 weeks. Results: The D/L-Tetra-Peptide Hydrogels resembled long bars with hinges on each other, with a diameter of ~10 nm. The H7N9 vaccine was observed to adhere to the hydrogel. All the unvaccinated mice were dead by 8 days post infection with H7N9. The mice immunized by the split H7N9 vaccine were protected against infection with H7N9. Mice immunized by D/L-Tetra-Peptide Hydrogel adjuvant vaccines experienced shorter symptomatic periods and their micro-neutralization titers were higher than in the split H7N9 vaccine at 2 weeks post infection. The hemagglutinating inhibition (HI) titer in the L-Tetra-Peptide Hydrogel adjuvant vaccine group was higher than that in the split H7N9 vaccine 1 week and 2 weeks post infection. The HI titer in the D-Tetra-Peptide Hydrogel adjuvant vaccine group was higher than that in the split H7N9 vaccine at 2 weeks post infection. Conclusion: The D/L Tetra-Peptide Hydrogels increased the protection of the H7N9 vaccine and could be promising adjuvants for H7N9 vaccines against highly pathogenic H7N9 virus.

Abstract
OBJECTIVE The purpose of this study was to investigate the correlations of cholesterol ester transfer protein (CTEP) TaqIB gene polymorphism with lipid metabolism abnormalities and cerebral infarction (CI) in patients with atherosclerosis (AS). PATIENTS AND METHODS A case-control study was conducted on 100 AS patients complicated with (CI) as AS+CI group, and 200 AS patients with matched age, gender and race as controls (AS group). Single nucleotide polymorphisms (SNPs) rs102313, rs118231 and rs201832 in the promoter region of CTEP TaqIB gene were classified by conformational differential gel electrophoresis. Then, Chi-square test was carried out to determine whether the distribution frequency of CTEP TaqIB genotypes conforms to the law of genetic equilibrium. In the meantime, the correlations of gene polymorphisms and allelotypes in the promoter region of CTEP TaqIB with CI and lipid metabolism abnormalities in AS patients were analyzed. RESULTS Hardy-Weinberg genetic equilibrium analysis showed that the three polymorphisms of CTEP TaqIB gene were in accordance with the genetic equilibrium distribution (p>0.05). Moreover, the results of gene association analysis revealed that the polymorphisms rs102313 and rs118231 and allelotypes in the promoter region of CTEP TaqIB gene were correlated with CI in AS patients (p<0.05). Specifically, AS patients with GG genotype and allele G at rs102313 and those with TT genotype and allele T at rs118231 had a higher risk of CI (p<0.05). Besides, the polymorphism rs102313 in the promoter region of CTEP TaqIB gene was markedly related to lipid metabolism abnormalities in AS patients (p<0.05). CONCLUSIONS The polymorphisms rs102313 and rs118231 in the promoter region of CTEP TaqIB gene are associated with CI in AS patients, and the polymorphism rs102313 is remarkably correlated with lipid metabolism abnormalities in AS patients.

Abstract
High-quality optical resonant cavities require low optical loss, typically on the scale of parts per million. However, unintended micron-scale contaminants on the resonator mirrors that absorb the light circulating in the cavity can deform the surface thermoelastically and thus increase losses by scattering light out of the resonant mode. The point absorber effect is a limiting factor in some high-power cavity experiments, for example, the Advanced LIGO gravitational-wave detector. In this Letter, we present a general approach to the point absorber effect from first principles and simulate its contribution to the increased scattering. The achievable circulating power in current and future gravitational-wave detectors is calculated statistically given different point absorber configurations. Our formulation is further confirmed experimentally in comparison with the scattered power in the arm cavity of Advanced LIGO measured by in situ photodiodes. The understanding presented here provides an important tool in the global effort to design future gravitational-wave detectors that support high optical power and thus reduce quantum noise.

Abstract
Drug-induced liver injury (DILI) is rare but clinically important due to a high rate of mortality. However, specific biomarkers for diagnosing and predicting the severity and prognosis of DILI are lacking. Here, we used targeted metabolomics to identify and quantify specific types of bile acids that can predict the severity of DILI. A total of 161 DILI patients were enrolled in this prospective cohort study, as well as 31 health controls. A targeted metabolomics method was used to identify 24 types of bile acids. DILI patients were divided into mild, moderate, and severe groups according to disease severity. A multivariate analysis was performed to identify characteristic bile acids. Then the patients were divided into severe and non-severe groups, and logistic regression was used to identify bile acids that could predict DILI severity. Among the enrolled DILI patients, 32 were in the mild group, 90 were in the moderate group, and 39 were in the severe group. Orthogonal partial least squares-discriminant analysis (OPLS-DA) modeling clearly discriminated among the different groups. Among the four groups, glycochenodeoxycholate (GCDCA), taurochenodeoxycholate (TCDCA), deoxycholic acid (DCA), Nor Cholic acid (NorCA), glycocholic acid (GCA), and taurocholic acid (TCA) showed significant differences in concentration between at least two groups. NorCA, GCDCA, and TCDCA were all independent risk factors that differentiated severe DILI patients from the other groups. The area under the receiver operating characteristic curve (AUROC) of GCDCA, TCDCA, and NorCA was 0.856, 0.792, and 0.753, respectively. Together, these three bile acids had an AUROC of 0.895 for predicting severe DILI patients. DILI patients with different disease severities have specific bile acid metabolomics. NorCA, GCDTA, and TCDCA were independent risk factors for differentiating severe DILI patients from less-severe patients and have the potential to predict DILI severity.

Abstract
This study was conducted between November to December 2020, consisting of six representative cities, Beijing, Shanghai, Shenzhen (with comprehensive smoke-free legislation), and Changsha, Chongqing, Shenyang (without comprehensive smoke-free legislation), 678 subjects were enrolled eventually, the mean age of the 678 subjects was (35.61±12.91)years old. Subjects from cities with comprehensive smoke-free legislation accounted for 49.71% of the total; male subjects accounted for 19.47%; meanwhile subjects from large, medium, and small restaurants accounted for 13.57% (92), 37.32% (253) and 49.11% (333) respectively. The analysis results indicate that the positive rate of restaurants staff of cotinine and 3'-hydroxynicotinine was lower in cities with comprehensive smoke-free legislation(34.12% vs 68.04%, χ²=78.01, P<0.001; 16.32% vs 41.94%, χ²=53.79, P<0.001), with staff from cities with comprehensive smoke-free legislation have lower concentrations of cotinine and 3'-hydroxynicotinine than their counterparts from cities without comprehensive smoke-free legislation(0.250 ng/ml vs 0.742 ng/ml, P<0.001; 0.250 ng/ml vs 0.250 ng/ml, P<0.001). No statistically significant difference in the concentration of cotinine and 3'-hydroxynicotinine in saliva between staff from restaurants of different sizes was detected (P>0.05).

Abstract
We introduce dynamic speckle holography, a new technique that combines imaging and scattering to measure three-dimensional maps of displacements as small as ten nanometers over several centimeters, greatly extending the capabilities of traditional imaging systems. We attain this sensitivity by imaging speckle patterns of light collected at three scattering angles and measuring the decay in the temporal correlation due to local motion. We use dynamic speckle holography to measure the strain field of a colloidal gel undergoing fracture and establish the surprising role of internal tension in driving the fracture.

Abstract
Tetanus is a fatal but vaccine-preventable disease. The currently available tetanus vaccines are tetanus toxoid (TT)-based. Although these vaccines are generally effective, challenges in vaccine development and access remain. A randomized, double-blind, dose escalation, placebo- and positive-controlled, phase 1/2 trial (ChiCTR1800015865) is performed to evaluate the safety and immunogenicity of an alternative recombinant tetanus vaccine based on the Hc domain of tetanus neurotoxin (TeNT-Hc) in healthy adult volunteers. The primary outcome is the safety profile of the recombinant tetanus vaccine, and immunogenicity is the secondary outcome. 150 eligible participants were enrolled and randomly assigned to receive one of the three doses of recombinant tetanus vaccine (TeNT-Hc 10/20/30 µg), TT vaccine, or placebo. The recombinant tetanus vaccine shows a good safety profile. The frequency of any solicited and unsolicited adverse events after each vaccination does not differ across the vaccine and placebo recipients. No serious treatment-related adverse events occur. The recombinant tetanus vaccine shows strong immune responses (seroconversion rates, geometric mean titer, and antigen-specific CD4+/CD8+ T-cell responses), which are roughly comparable to those of the TT vaccine. In conclusion, the findings from this study support that recombinant tetanus vaccine is safe and immunogenic; thereby, it represents a novel vaccine candidate against tetanus.

Abstract
Purpose: Neutrophils and cytokines play a major role in the pathogenesis of acute-on-chronic liver failure (ACLF). We aimed to determine whether chemokine (CXC) ligand 1 (CXCL1), a key marker of neutrophil recruitment and activation, could predict the severity and prognosis of hepatitis B virus–related ACLF (HBV-ACLF). Methods: Hospitalized patients with HBV-ACLF were enrolled in a prospective study and stratified as survivors (alive at 28 days) and nonsurvivors (deceased at 28 days). Serum CXCL1 levels were measured in healthy controls, patients with chronic HBV, patients with HBV-related compensated cirrhosis, and patients with HBV-ACLF. Univariate and multivariable logistic analyses, Pearson correlation analysis, area under the receiver operating characteristic curve (AUROC), and Z tests were used to evaluate the performance of CXCL1 as a marker in HBV-ACLF. Results: Patients with HBV-ACLF had significantly higher serum levels of CXCL1 and neutrophil count than healthy controls and patients with chronic HBV or HBV-related compensated cirrhosis (P < 0.01, respectively). Among patients with HBV-ACLF, survivors had lower serum CXCL1 levels and neutrophil count than those of nonsurvivors (P < 0.001, P < 0.05, respectively). Serum CXCL1 level was positively correlated with neutrophil count (r = 0.256, P = 0.001), ACLF grade (r = 0.295, P < 0.001) and organ failure, including coagulation (r = 0.21, P = 0.005) and brain failure (r = 0.198, P = 0.008). Multivariable logistic analyses showed serum CXCL1 [OR (95% CI) = 1.017 (1.009–1.025), P < 0.001] was an independent risk factor for 28-day mortality in HBV-ACLF. Meanwhile, the AUROC analysis demonstrated that serum CXCL1 [0.741 (0.669–0.804)] might be a reliable prognostic biomarker for patients with HBV-ACLF. Conclusions: Overall, serum CXCL1 can serve as a biomarker indicating the severity of disease and prognosis for patients with HBV-ACLF. CXCL1 might also be a therapeutic target in this disease.

Abstract
The motion of a mechanical object, even a human-sized object, should be governed by the rules of quantum mechanics. Coaxing them into a quantum state is, however, difficult because the thermal environment masks any quantum signature of the object's motion. The thermal environment also masks the effects of proposed modifications of quantum mechanics at large mass scales. We prepared the center-of-mass motion of a 10-kilogram mechanical oscillator in a state with an average phonon occupation of 10.8. The reduction in temperature, from room temperature to 77 nanokelvin, is commensurate with an 11 orders-of-magnitude suppression of quantum back-action by feedback and a 13 orders-of-magnitude increase in the mass of an object prepared close to its motional ground state. Our approach will enable the possibility of probing gravity on massive quantum systems.

Constraints on Cosmic Strings Using Data from the Third Advanced LIGO-Virgo Observing Run. PHYSICAL REVIEW LETTERS 2021; 126:241102. [PMID: 34213926 DOI: 10.1103/physrevd.97.102002] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Revised: 03/31/2021] [Accepted: 05/23/2021] [Indexed: 05/21/2023]
Abstract
We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic string loop features such as cusps, kinks, and, for the first time, kink-kink collisions. A template-based search for short-duration transient signals does not yield a detection. We also use the stochastic gravitational-wave background energy density upper limits derived from the O3 data to constrain the cosmic string tension Gμ as a function of the number of kinks, or the number of cusps, for two cosmic string loop distribution models. Additionally, we develop and test a third model that interpolates between these two models. Our results improve upon the previous LIGO-Virgo constraints on Gμ by 1 to 2 orders of magnitude depending on the model that is tested. In particular, for the one-loop distribution model, we set the most competitive constraints to date: Gμ≲4×10^{-15}. In the case of cosmic strings formed at the end of inflation in the context of grand unified theories, these results challenge simple inflationary models.

Abstract
We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic string loop features such as cusps, kinks, and, for the first time, kink-kink collisions. A template-based search for short-duration transient signals does not yield a detection. We also use the stochastic gravitational-wave background energy density upper limits derived from the O3 data to constrain the cosmic string tension Gμ as a function of the number of kinks, or the number of cusps, for two cosmic string loop distribution models. Additionally, we develop and test a third model that interpolates between these two models. Our results improve upon the previous LIGO-Virgo constraints on Gμ by 1 to 2 orders of magnitude depending on the model that is tested. In particular, for the one-loop distribution model, we set the most competitive constraints to date: Gμ≲4×10^{-15}. In the case of cosmic strings formed at the end of inflation in the context of grand unified theories, these results challenge simple inflationary models.

Abstract
AIMS Klebsiella pneumoniae has been reported to develop increased antibiotic resistance. Ceftazidime-avibactam (CZA) is a novel antibiotic with activity against serine-lactamase. Here, we investigated the sensitivity of carbapenem-resistant K. pneumoniae (CRKP) to CZA and the mechanisms of drug resistance in our hospital. METHODS AND RESULTS Patient characteristics were obtained from medical records. K. pneumoniae and its antibiotic susceptibility were determined using the Vitek-2 Compact instrument. The antibiotic resistance genes KPC, NDM, OXA-48, VIM, IMP, CIM, SPM, TMB, SMB, SIM, AIM and DIM were detected using real-time PCR. Multilocus sequence typing was used for genetic RELATEDNESS analysis. In total, 121 CRKP strains were isolated from patients in the intensive care unit (51·2%), senior ward (12·4%) and neurosurgery department (10%). With an average age of 72·5 years, most patients were in care for respiratory (34·7%), brain (20·7%), digestive tract (13·2%) and cardiovascular (8·3%) diseases. Specimens were predominantly obtained from sputum (39·67%), urine (29·75%) and blood (6·61%). CONCLUSION Of 23 CZA-resistant CRKP strains (19·01%), ST11 being the most common at 56·52%, 11 NDM-1-positive (47·83%) and four NDM-5-positive (17·39%) strains were detected. SIGNIFICANCE AND IMPACT OF THE STUDY Our study indicates that CZA resistance occurs in ~19·01% CRKP strains and that blaNDM-1 and blaNDM-5 might be critical for resistance.

Abstract
Fibroblast growth factor 2 (FGF2) is important in musculoskeletal homeostasis, therefore the impact of reduction or Fgf2 knockout on skeletal muscle function and phenotype was determined. Gait analysis as well as muscle strength testing in young and old WT and Fgf2KO demonstrated age-related gait disturbances and reduction in muscle strength that were exacerbated in the KO condition. Fgf2 mRNA and protein were significantly decreased in skeletal muscle of old WT compared with young WT. Muscle fiber cross-sectional area was significantly reduced with increased fibrosis and inflammatory infiltrates in old WT and Fgf2KO vs. young WT. Inflammatory cells were further significantly increased in old Fgf2KO compared with old WT. Lipid-related genes and intramuscular fat was increased in old WT and old Fgf2KO with a further increase in fibro-adipocytes in old Fgf2KO compared with old WT. Impaired FGF signaling including Increased β-Klotho, Fgf21 mRNA, FGF21 protein, phosphorylated FGF receptors 1 and 3, was observed in old WT and old Fgf2KO. MAPK/ ERK1/2 was significantly increased in young and old Fgf2KO. We conclude that Fgf2KO, age-related decreased FGF2 in WT mice, and increased FGF21 in the setting of impaired Fgf2 expression likely contribute to impaired skeletal muscle function and sarcopenia in mice.

Abstract
OBJECTIVE Amongst noncoding RNAs, competing endogenous RNAs (ceRNAs) are popular and interesting regulatory mechanisms involved in oncogenesis and tumour progression. LncRNA FGD5-AS1, also known as miR-5590-3p, is involved in the regulatory role of ceRNA in many cancers. However, the roles of lncRNA FGD5-AS1 or miR-5590-3p in renal cell carcinoma (RCC) remain unclear. We investigated how FGD5-AS1 and miR-5590-3p regulated clear cell proliferation and metastasis in RCC. PATIENTS AND METHODS Real Time-quantitative PCR (RT-qPCR) was used to detect the expression of FGD5-AS1 in tumour issues and renal cancer cell lines. MTT, scratch test and transwell assay were performed to confirm the effect of FGD5-AS1 on the proliferation, migration or invasion of the above cell lines. RNA pull-down and Luciferase assays were used to detect the target site between FGD5-AS1 and miR-5590-3p. In addition, we examined the proteins related to ERK/AKT signalling related via Western blot analysis. Finally, we used the RT-qPCR method to detect the mRNA levels of E-cadherin and vimentin. RESULTS LncRNA FGD5-AS1 was highly expressed in renal cancer tissues, especially in patients with metastasis. This effect facilitated the proliferation, migration, epithelial-mesenchymal transition and invasion of renal cancer cells. Silencing the expression of FGD5-AS1 with FGD5-AS1 siRNA significantly inhibited the malignancy of tumour cells. RNA pull-down and Luciferase assays demonstrated that FGD5-AS1 targeted miR-5590-3p to interact with miR-5590-3p negatively. Furthermore, miR-5590-3p inhibitors could eliminate the FGD5-AS1 siRNA-induced upregulation of E-cadherin and downregulation of vimentin. CONCLUSIONS Mechanistically, lncRNA FGD5-AS1 can competitively interact with miR-5590-3p and regulate the downstream signalling of ErkAKT to enhance the malignancy of tumours. This lncRNA could become a potential target molecule for treating and diagnosing RCC.

Abstract
Abstract Objective To establish the orthogonal partial least square (OPLS) model for the estimation of early postmortem interval (PMI) of asphyxial death rats in four ambient temperatures based on gas chromatography-mass spectrometry (GC-MS) metabolomics. Methods The 96 rats were divided into four temperature groups (5 ℃, 15 ℃, 25 ℃ and 35 ℃). Each temperature group was further divided into 3 h, 6 h, 12 h and 24 h after death, and 6 other rats were taken as the control group. The cardiac blood was collected at the set time points for the four temperature groups and 0 h after death for the control group for the metabolomics analysis by GC-MS. By OPLS analysis, the variable importance in projection (VIP)>1 and the result of Kruskal-Wallis test P<0.001 were used to screen out the differential metabolite related to PMIs in the cardiac blood of rats of different temperature groups. Then OPLS regression models of different temperature groups were established with these metabolites. At the same time, a prediction group for investigating the prediction ability of these models was set up. Results Through the analysis of OPLS, 18, 15, 24 and 30 differential metabolites (including organic acids, amino acids, sugars and lipids) were screened out from the rats in groups of 5 ℃, 15 ℃, 25 ℃ and 35 ℃, respectively. The prediction results of the four temperature group models showed that the prediction deviation of 5 ℃ model was larger than that of other groups. The prediction results of other temperature groups were satisfactory. Conclusion There are some differences in the changes of metabolites in cardiac blood of rats at different ambient temperatures. The influence of ambient temperature should be investigated in the study of PMI estimation by metabolomics, which may improve the accuracy of PMI estimation.

Abstract
OBJECTIVE By establishing osteoporosis (OP) model in rats, the specific regulatory effect of simvastatin on promoting the differentiation of mesenchymal stem cells (MSCs) into osteoblasts through the bone morphogenetic protein 2 (BMP-2)/Smads signaling pathway was investigated. MATERIALS AND METHODS A total of 45 Sprague-Dawley rats were selected to establish the OP model by performing ovariectomy. The rats were divided into OP model group (OP group, n=15), 10-7 mmol/L simvastatin treatment group (SIM group, n=15), and normal control group (Control group, n=15). After the experimental period, the enzyme-linked immunosorbent assay (ELISA) was applied to observe the serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and IL-1. Reverse Transcription-Polymerase Chain Reaction (RT-PCR) was adopted to detect the contents of the differentiation-associated genes [runt-related transcription factor 2 (RUNX2) and Osterix (Osx)]. Later, the bone marrow MSCs (BMSCs) were selected and divided into Control group, 10-7 mol/L simvastatin group (SIM group), and osteoinduction medium group (OM group). Cell morphology in each group was observed. The Cell Counting Kit-8 (CCK-8) was performed to determine the proliferation activity of BMSCs. ELISA was performed to measure the level of alkaline phosphatase (ALP). RT-PCR was conducted to examine the levels of key differentiation-associated gene RUNX2 and those in BMP-2/Smads pathway. Moreover, the Western blotting was adopted to analyze the expressions of RUNX2 and genes in BMP-2/Smads pathway. RESULTS The serum levels of TNF-α, IL-6, and IL-1 in OP group were remarkably higher than those in the Control group, and their levels in the SIM group were close to those in the Control group. The elevated messenger ribonucleic acid (mRNA) levels of the key differentiation-associated factors RUNX2, osteoprotegerin (OPG), osteopontin (OPN), and Osx were observed in the SIM group. In vitro cell culture revealed that the cells were in a favorable growth status in the SIM group and OM group, mostly manifesting in fusiform or spindle shape, and proliferated rapidly. In addition, the ALP level notably increased in the two groups compared with that in the Control group (p<0.05). Both SIM group and OM group had evidently higher mRNA expression levels of RUNX2, OPG, OPN, and Osx than those in the Control group (p<0.05), consistent with the expression trends of the genes in BMP-2/Smads pathway. The Western blotting indicated that the expression levels of RUNX2 and genes in BMP-2/Smads pathway in the SIM group were significantly higher than those in the Control group. CONCLUSIONS Simvastatin can promote the differentiation of MSCs into osteoblasts in the OP rat model through the BMP-2/Smads signaling pathway.

Abstract
BACKGROUNDHBV-related acute-on-chronic liver failure (HBV-ACLF) is hallmarked by high short-term mortality rates, calling for accurate prognostic biomarkers for initial risk stratification.METHODSThree tandem mass tag-labeled (TMT-labeled) quantitative proteomic studies were performed on 10 patients with HBV-related acute hepatic decompensation and on 20 patients with HBV-ACLF. Candidate biomarkers were preliminarily verified in a cross-sectional cohort (n = 144) and further confirmed in 2 prospective cohorts (n = 207 and n = 148).RESULTSPlasminogen, a potential prognostic biomarker for HBV-ACLF, was identified by TMT quantitative proteomics and preliminarily verified in the cross-sectional cohort. Further validation with a prospective cohort (n = 207) showed that plasminogen levels at admission were significantly lower (P < 0.001) in HBV-ACLF nonsurvivors than in survivors. The cumulative survival duration of patients with high plasminogen levels was significantly longer (P < 0.001) than that of patients with low plasminogen levels. During hospitalization, plasminogen levels significantly decreased (P = 0.008) in the deterioration group but significantly increased (P < 0.001) in the improvement group. Additionally, plasminogen levels gradually increased in survivors but gradually decreased in nonsurvivors. The P5 score, a prognostic panel incorporating plasminogen levels, hepatic encephalopathy occurrence, age, international normalized ratio (INR), and total bilirubin, was significantly superior to the Child-Pugh, Model for End-stage Liver Disease (MELD), Chronic Liver Failure Consortium ACLF (CLIF-C ACLF), Chinese Group on the Study of Severe Hepatitis B (COSSH), and HINT (a prognostic score based on hepatic encephalopathy occurrence, INR, neutrophil count, and thyroid-stimulating hormone) scores (all P < 0.05). The performances of the plasminogen level and P5 score were validated in a second multicenter, prospective cohort (n = 148).CONCLUSIONSPlasminogen is a promising prognostic biomarker for HBV-ACLF, and sequential plasminogen measurements could profile the clinical course of HBV-ACLF. P5 is a high-performance prognostic score for HBV-ACLF.FUNDINGThe National Key Research and Development Program (2017YFC1200204); the National Natural Science Foundation of China (81400589, 81600497); the Foundation for Innovative Research Groups of the National Natural Science Foundation of China (81121002); the Chinese High-Tech Research and Development Programs (2012AA020204); the National S&T Major Project (2012ZX10002004); and the Zhejiang Provincial Medicine and Health Science and Technology Project (2016147735).

Abstract
Objective: To compare the infection of BK virus in the recipients of living donor(LD) kidney transplant and deceased donor(DD) kidney transplant. Methods: A total of 911 recipients who underwent kidney transplantation in the Organ Transplantation Research Institute of the 8th Medical Center of the People's Liberation Army General Hospital from January 2015 to August 2019 were enrolled in this study. The DNA copies of BK virus in urine and peripheral blood of kidney transplant recipients were detected by real-time quantitative PCR. The patients were divided into LD group (n=255) and DD group (n=656). BK virus infection in recipients with DD kidney transplant were compared with that in recipients of LD kidney transplant. Results: The BK virus positive rate in the urine of all subjects was 13.06%(119/911), and that in blood was 2.96% (27/911). The positive rate of BK virus in urine after kidney transplantation was significantly higher than that in blood(P<0.000 1). The positive rate in urine was 9.02% (23/255) in LD group, which was significantly lower than that of 14.63% (96/656) in DD group in the same period (χ(2)=5.097, P=0.012); The positive rate of BK virus infection in relatives group was 0.78% (2/255), which was significantly lower than that of 3.81% (25/656) in DD group (χ(2)=5.849, P=0.007). Conclusions: There was a significant difference in the infection rate of BK virus between the LD and DD group. The incidence of BK virus infection in kidney transplant recipients from DD was higher than that of from LD kidney transplant recipients.

Abstract
OBJECTIVE After 131I treatment in patients with differentiated thyroid carcinoma (DTC), we sometimes find a star-shaped intense uptake of 131I on therapeutic whole body scans (Rx-WBS), called star artifacts. Therefore, we analyzed the relevant clinical factors and prognostic value of star artifacts in DTC patients. METHODS 809 DTC patients who received 131I treatment were retrospectively evaluated and divided into 2 groups of patients with and without star artifacts. We evaluated the therapeutic response which was divided into excellent response (ER), biochemical incomplete response (BIR), indeterminate response (IR), and structural incomplete response (SIR). Clinical factors for the presence of star artifacts were analyzed. We also compared the rate of ER, BIR, IR, SIR and recurrence rate between group 1 and group 2. RESULTS The major clinical factors included stimulated thyroglobulin (sTg)>1.8ng/ml, 24h radioiodine uptake (RAIU)>2.2%, and positive 99mTcO4- thyroid imaging for the presence of star artifacts. In patients with sTg levels>10ng/ml, patients in group 1 had a higher rate of ablation success and ER than patients in group 2 (80.2% vs 65.6%, P=0.038, 31.6% vs 13.1%, P=0.008, respectively) and had a similar rate of BIR, IR, SIR. Recurrence rate was similar between group 1 and group 2 (5.2% vs 3.1%, P=0.13). CONCLUSION More remnant thyroid tissue is one of the factors associated with the presence of star artifacts on Rx-WBS. Patients with star artifacts exhibit a better therapeutic response (ER) when sTg levels are >10ng/ml. However, star artifacts have no effect on the recurrence rate.

Abstract
This study investigated the safety and efficacy of ravidasvir (RDV) plus ritonavir-boosted danoprevir (DNVr) and ribavirin (RBV) regimens for treatment-naïve non-cirrhotic patients with hepatitis C virus (HCV) genotype 1b in mainland China. We also gained insight into HCV-host interactions during anti-HCV treatment. 16 patients with HCV and 10 healthy people enrolled the study. Three of 16 patients received 12-weeks' placebo treatment first and served as the placebo controls. All (n = 16) patients received 12-weeks' RDV plus DNVr and RBV treatment. The adverse effects (AEs), viral loads, alanine transaminase, and aspartate aminotransferase were recorded during study. We also performed multianalyte profiling of 48 cytokines/chemokines in 16 patients with HCV and 10 normal controls. Seventy-five percent patients treated with RDV plus DNVr and RBV experienced AEs. No death, treatment-related serious AEs or AEs leading to discontinuation were reported. The serum HCV-RNA levels remained extremely high in 3 placebo controls after treated with placebo. After RDV plus DNVr and RBV treatment, all patients achieved sustained virologic response (SVR) at posttreatment week 12, but 1 patient experienced viral relapse at SVR 24. The cytokine/chemokine expression pattern was markedly altered in patients with HCV as compared with healthy controls. The interferon-inducible protein-10 (IP-10) decreased after anti-HCV treatment, and dramatically increased in one patient with viral relapse. The regimen of RDV and DNVr plus RBV represents a highly safe and effective treatment option for HCV patients in mainland China. The IP-10 has the potential to be an indicator of innate immune viral recognition.

Abstract
AIM To investigate the brain magnetic resonance imaging (MRI) features of children with haemophagocytic lymphohistiocytosis (HLH) with central nervous system (CNS) involvement, and to investigate the correlation with clinical biochemical tests. MATERIAL AND METHODS Clinical and MRI data were collected from 118 children with HLH-CNS between January 2012 and June 2019. Patients were grouped according to their MRI findings, and statistical methods were used to test for correlations between the MRI findings and biochemical variables. RESULTS Patients were divided into three groups, including normal appearance (Group 1, 17/118), diffuse parenchymal volume loss (Group 2, 44/118), and brain parenchyma lesions (Group 3, 57/118) containing three subtypes of brain lesions and HLH-CNS complications. Comparing biochemical values among the three groups revealed a significant difference for all values (p<0.05), except for cell counts in the cerebrospinal fluid (CSF). A pairwise comparison further showed significant inter-group differences for most of the variables. Spearman's rank correlation coefficient also demonstrated that CSF cell counts (r=0.193, p=0.036), CSF microprotein content (r=0.379, p<0.001), serum aspartate aminotransferase (AST; r=0.521, p<0.001), serum lactate dehydrogenase (LDH; r=0.514, p<0.001) and activated partial thromboplastin time (APTT; r=0.326, p<0.001) correlated positively with the MRI groups, while platelet count (PLT; r=-0.633, p<0.001) and plasma fibrinogen (FIB; r=-0.258, p=0.005) correlated negatively. CONCLUSION Classification of brain MRI findings of HLH-CNS correlates well with the results of several key biochemical tests. Brain MRI is a promising method to elucidate illness severity and clinical outcomes.

Abstract
On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio of 14.7, and an estimated false-alarm rate of 1 in 4900 yr using a search sensitive to generic transients. If GW190521 is from a quasicircular binary inspiral, then the detected signal is consistent with the merger of two black holes with masses of 85_{-14}^{+21} M_{⊙} and 66_{-18}^{+17} M_{⊙} (90% credible intervals). We infer that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, with only a 0.32% probability of being below 65 M_{⊙}. We calculate the mass of the remnant to be 142_{-16}^{+28} M_{⊙}, which can be considered an intermediate mass black hole (IMBH). The luminosity distance of the source is 5.3_{-2.6}^{+2.4} Gpc, corresponding to a redshift of 0.82_{-0.34}^{+0.28}. The inferred rate of mergers similar to GW190521 is 0.13_{-0.11}^{+0.30} Gpc^{-3} yr^{-1}.
