Published: December 2022

Abstract
Background
Cardiac trauma is associated with a high mortality rate, but a subset of the patients presents with normal vital signs in the emergency department. Identification of cardiac injuries in these patients can be a challenge. Many investigative modalities have been used to identify penetrating cardiac injury patients. Most of these tests are expensive, specialised and not easily accessible. However, the role of Troponins in penetrating cardiac injury has not been defined. We hypothesised that cardiac troponins have a negative predictive value in penetrating cardiac injuries.
Materials and methods
We retrospectively reviewed all patients who presented to the Charlotte Maxeke Academic Hospital trauma unit over 22 months (January 2018 to October 2020). Patients were identified using the hospital database. All patients with penetrating cardiac trauma to the cardiac zone above the age of 16 years were included.
The patient’s demographics, mechanism of injury, injury severity score, vital signs, investigation findings, troponin levels, final diagnosis, type of operation, length of hospital stay, morbidities and mortalities were recorded.
Results
There was a total of 173 patients identified; 6 were females. The median age was 30 years. Most patients (160/173, 92%) had stab wounds. The median Injury Severity Score (ISS) was 12.8. Most patients sustained stab wounds on the left side of the chest (n=90), 52%. Initial ultrasound was positive for pericardial fluid in 10% of patients (n=18). The sensitivity of cardiac troponins was 19.7%, and the specificity was 98.2%. The negative and positive predictor values were 69.2% and 85.7%, respectively. The mean initial Troponins level was 50 ng/L. The mean repeat troponins were 450 ng/L in those patients with cardiac injuries. The Troponins were significantly different in those with cardiac injuries and those without cardiac injuries. In patients who had a cardiac injury, the right ventricle (3.5%) was the most commonly injured chamber, followed by the left ventricle (2.3%) and Right atrium (0.6%). Two patients sustained myocardial injuries without chamber penetration. The overall mortality rate was 0,6%(n=1). Fifty percent of the patients (n=87) were discharged home from the emergency department, 21.8% were admitted to the ward (n=38), and 15.5% (n=27) were admitted to the Trauma ICU. The average hospital stay was one day for patients with a stab to the precordium.
Conclusion
Troponins can be used to evaluate cardiac injuries in haemodynamically stable patients with penetrating chest trauma. It is highly specific for cardiac injuries (98%). More prospective data is needed to confirm our findings and then extend to clinical practice, especially in resource-limited environments.

Published: December 2022

Abstract
Idiopathic scoliosis (IS) is the deformation and/or abnormal curvature of the spine that develops progressively after birth. It is a very common condition, affecting approximately 4% of the general population, yet the genetic and mechanistic causes of IS are poorly understood. Here, we focus on PPP2R3B, which encodes a protein phosphatase 2A regulatory subunit that has been linked to regulation of autophagy. We found that PPP2R3B is expressed at sites of chondrogenesis within human foetuses, including the vertebrae. We also demonstrated prominent expression in myotome and muscle fibres in human foetuses, and zebrafish embryos and adolescents. As there is no rodent orthologue of PPP2R3B, we used CRIPSR/Cas9-mediated gene-editing to generate a series of frameshift mutations in zebrafish ppp2r3b. Adolescent zebrafish that were homozygous for this mutation exhibited a fully penetrant kyphoscoliosis phenotype which became progressively worse over time, mirroring IS in humans. These defects were associated with reduced mineralisation of vertebrae, resembling osteoporosis. Electron microscopy demonstrated abnormal mitochondria adjacent to muscle fibres, suggestive of abnormal mitophagy.

Abstract

Background: Kusuantongtiao Formula (KSTTF) have been shown to be effective in treating insulin resistance (IR) of type 2 diabetes (T2DM), but the mechanism by which KSTTF remains unclear. Objective This study revealed the pharmacological mechanisms of KSTTF acting on IR through network pharmacology, molecular docking, dynamics andvitroexperiments. Materials and methods In this study, the ingredients and potential targets of KSTTF were obtained from the TCMSP and HERB databases, and the potential targets of IR were obtained from GeneCard and OMIM database. Cytoscape 3.9.1 constructed network and predicted potential active ingredients and targets. Protein–protein interaction network was constructed using the STRING. AutoDock Vina was used for molecular docking between active ingredients and targets. Subsequently, molecular dynamics simulation was used to analyze the conformational stability of the protein-ligand complexes by GROMACS. Furthermore, the effect and mechanism of KSTTF on insulin resistance were verified by cell viability assay, glucose uptake and western blotting. Results In the formula, we found 172 potential active compounds, such as berberine, baicalin, rhein. A total of 270 intersection targets of KSTTF and IR were obtained, including peroxisome proliferator-activated receptor-gamma (PPARG), glycogen synthase kinase 3β (GSK3B), nitric-oxide synthase (NOS2), and dipeptidyl peptidase 4 (DPP4). Gene ontology and KEGG pathway enrichment revealed that KSTTF could regulate PI3K/Akt signaling pathway. The results of molecular docking showed that GSK3B-1,2,5,6-tetrahydrotanshinone, NOS2-1,2,5,6-tetrahydrotanshinone, PPARG-1,2,5,6-tetrahydrotanshinone, and DPP4-cryptotanshinone had higher binding energy. Molecular dynamics simulation verified the stability of PPARG-1,2,5,6- tetrahydrotanshinone. Binding free energy analysis showed that van der Waals interaction was the main binding form of protein and ligand. Finally, the result fromvitroexperiments showed that KSTTF improved glucose consumption and increased the phosphorylation levels of IRS1, PI3K, and Akt in palmitic acid-induced C2C12. Conclusions This study predicted the active components and potential targets of KSTTF through network pharmacology, and analyzed its possible mechanism of action in the treatment of insulin resistance. The key targets were validated by molecular docking and molecular dynamics simulation. Thevitroexperiments confirmed that KSTTF may treat IR by promoting IRS1/PI3K/Akt conduction and glucose uptake consumption. We possess a reason to believe that their mechanisms for insulin resistance are synergy between several different signaling pathways and targets. However, further experiment is crucial to reveal the effect of KSTTF on insulin resistance.

Published: December 2022

Abstract
Objectives
To clarify the relationship between the PaO2/FiO2 and 28-day mortality in patients with sepsis.
Methods
This was a retrospective cohort study regarding MIMIC- IV database. A total of 35,010 patients with sepsis were included in this database. PaO2/FiO2 was exposure variable, 28-day mortality was outcome variable. PaO2/FiO2 was log-transformed as LnPaO2/FiO2. Binary logistic regression was used to explore the independent effects of LnPaO2/FiO2 on 28-day mortality using non-adjusted and multivariate-adjusted models. A generalized additive model (GAM) and smoothed curve fitting were used to investigate the non-linear relationship between LnPaO2/FiO2 and 28-day mortality. A two-piecewise linear model was used to calculate the OR and 95% CI on either side of the inflection point.
Results
A total 19,233 cases were included in the final analysis. The relationship between LnPaO2/FiO2 and risk of 28-day death in sepsis patients was U-shape. The inflection point of LnPaO2/FiO2 was 5.32(95%CI:5.22–5.39), which indicated the inflection point of PaO2/FiO2 was 204.38mmHg (95%CI: 184.93mmHg − 219.20mmHg). On the left of inflection point, LnPaO2/FiO2 was negatively correlated with 28-day mortality(OR:0.38, 95%CI༚0.33, 0.44, p < 0.0001). On the right of inflection point, LnPaO2/FiO2 was positively correlated with 28-day mortality in patients with sepsis (OR:1.67,95%CI༚1.42, 1.96, p < 0.0001).
Conclusions
In patients with sepsis, either a high or low PaO2/FiO2 was associated with an increased risk of 28-day mortality. In the range of 184.93mmHg to 219.20 mmHg, PaO2/FiO2 was associated with a lower risk of 28-day death in patients with sepsis.

AbstractBackground and Aim:At present, DAAs are very effective in the treatment of HCV, but there are still a small number of patients with treatment failure. Sofosbuvir/velpatavir/voxilaprevir (SOF/VEL/VOX) is a first-line retreatment recommended by HCV guidelines. The sustained virological response rate at 12 weeks (SVR12) of phase Ⅲ clinical studies reached 97%. However, SOF/VEL/VOX was only allowed into the health insurance list in January 2022 in China. So there are few data on the effectiveness and safety of SOF/VEL/VOX in East China. Meanwhile, there is a lack of international data on genotype (GT)3b retreatment therapy. This is the first real-life cohort study evaluating effectiveness and safety of SOF/VEL/VOX in prior direct-acting antiviral failure HCV from multi-center of East China. The aim of this study was to evaluate the effectiveness and safety of SOF/VEL/VOX retreatment in HCV patients with DAAs failure.Methods:A total of 13 patients with HCV who failed treatment in multiple centers in East China from January 2022 to March 2022 were collected and received 12w SOF/VEL/VOX antiviral treatment. HCV RNA, blood routine, liver and kidney function, abdominal color ultrasound or CT were measured at baseline, 4 weeks, 8 weeks, 12weeks and follow-up of 12 weeks. Virological response rate was used to evaluate the direct antiviral efficacy.Results:A total of 13 previous DAA failure HCV patients received 12w SOF/VEL/VOX without Ribavirin (RBV) retreatment, with an average age of 44.2 ± 8.5 years, with male predominance (92.3%). There were 6 patients with genotype GT3b, 5 patients of GT6（4 GT6a and 1 GT6n）, 2 patients of GT1b. All patients are non-cirrhotic patients, including 2 patients with PWID. Previous treatment included Sofosbuvir + Velpatavir, Coblopasvir + Hydrochloride + Sofosbuvir, Elbasvir + Grazoprevir. The mean value of baseline HCV-RNA was 9.45*106copies/ml, ALT was 231.6±218.1U/L, and AST was 150.7±166.4U/L. SVR12 was 100%. The common adverse reactions were gastrointestinal reactions and dizziness, which were well tolerated by the patients. No serious adverse events, death or treatment discontinuation occurred due to adverse reactions.Conclusion:SOF/VEL/VOX is an effective and safe retreatment for patients with HCV who have failed on a previous DAA course in a real-life setting, and has a good virological response rate for HCV patients with different genotypes of treatment failure even for refractory GT3b.

Abstract
Indigenous Iranian horse breeds were evolutionarily affected by natural and artificial selection in distinct phylogeographic clades which shaped their genomes in several unique ways. The principal aims of this study were to evaluate genetic diversity and genome-wide selection signatures in four indigenous Iranian horse breeds. We evaluated 169 horses from Caspian (n = 21), Turkmen (n = 29), Kurdish (n = 67) and Persian Arabian (n = 52) populations, using genome-wide genotyping data. The contemporary effective population sizes were 59, 98, 102 and 113 for Turkmen, Caspian, Persian Arabian, and Kurdish, respectively. Analysis of population genetic structure classified the north breeds (Caspian and Turkmen) and west/southwest breeds (Persian Arabian and Kurdish) into two phylogeographic clades reflecting their geographic origin. Using de-correlated composite of multiple selection signals (DCMS) statistics based on six pairwise comparisons, we detected different number of significant SNPs under putative selection from 13 to 28 for the six pairwise comparisons (FDR < 0.05), respectively. The identified SNPs under putative selection coincided with genes previously associated with known QTLs for morphological, adaptation and fitness traits. Our results showed HMGA2 and LLPH as strong candidate genes for height variation between Caspian with a small size and the other studied breeds with a medium size. Using results of studies for human height retrieved from the GWAS catalog, we suggested 38 new putative candidate genes under selection. These results suggest that the identified sweeps might have been enriched as an adaptation to environmental conditions or a response to human-mediated artificial selection.

Authors: Gao Han , Wei Wei , Li Yibing , wang ning 
Published: December 2022

Abstract
Purpose
To determine the recurrence rate in the women with controlled ovarian hyperstimulation after a history of borderline ovarian tumors (BOT).
Methods
This was a retrospective analysis of 275 patients with BOT undergoing surgery for fertility preservation in our hospital between 2001 and 2017. Cases were divided into an assisted reproductive technology (ART) treatment group (n = 15) and a non-ART treatment group (n = 260). We compared the recurrence rate, survival rate and pregnancy outcomes between these two groups.
Results
The ART group had a higher recurrence rate (33.33% vs. 10.80%, P = 0.023). Survival analysis indicated that the recurrence time in patients undergoing ART was significantly shorter (P = 0.026). A low pregnancy rate before diagnosis, and high intraoperative blood loss, were associated with postoperative ART treatment (P < 0.05). Multivariate analysis showed that ART treatment and bilateral lesions both significantly increased the risk of recurrence (P < 0.05). The pathological type of recurrent tumors was often the same as the initial tumor.
Conclusion
The postoperative use of ART in patients with BOT significantly increased the recurrence rate, but does not significantly affect the overall survival rate of patients. Therefore, ART in such patients should be individualized, and close follow-up is necessary after ART.

Authors: Jiang Bin , Ji Simin , Zhao Peiyi , Fan Lili 
Published: December 2022

Abstract
The friction contact boundary between the tool flank of the milling cutter and the machining transition surface is important indicator to reveal the third deformation zone tool contact relationship and assessing the frictional wear performance of milling cutter. The existing models for friction boundary identification pay attention to the maximum width of accumulated friction and wear on the tool flank, ignoring the variability of the overall and local morphology of the friction boundary on the flank. Aimed at the influence of milling vibration on the instantaneous position of the cutter teeth and the machining transition surface, the solution and discrimination for the instantaneous position vector on the flank was proposed. Based on the mutagenicity of the instantaneous temperature and stress distribution, the influence of the instantaneous contact, extrusion and deformation between the tool flank and the machined transition surface on the friction area was recognized. The calculation model of friction boundary of the flank was established. The irregularities of the distributions of the friction boundaries of the tool flank were revealed. The fractal recognition methods for instantaneous and cumulative friction boundary of the flank were proposed. And response was studied and verified with experiments. The results showed that it could effectively identify the irregular distribution of the friction boundary on the flank with the use of the above models. The formation and evolution of the friction boundary on the tool flank of the high-energy-efficiency milling cutters were revealed.

Abstract
In clinical practice, the underlying pathogenesis of Parkinson’s disease (PD) remains unknown. Circular RNAs (circRNAs) have good biological properties and can be used as biological marker. Rehabilitation as a third treatment alongside drug and surgical has been shown to be clinically effective, but biomarkers of rehabilitation efficiency at genetic level is still lacking. In this study we identified differentially expressed circRNAs in peripheral blood exosomes between PD patients and health controls (HCs) and determined whether these circRNAs changed after rehabilitation, to explore the competing RNA networks and epigenetic mechanisms affected. We found that there were 558 upregulated and 609 downregulated circRNAs in PD patients compared to HCs, 3398 upregulated and 479 downregulated circRNAs in PD patients after rehabilitation compared to them before rehabilitation, along with 3721 upregulated and 635 downregulated circRNAs in PD patients after rehabilitation compared to HCs. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis revealed that differentially expressed circRNAs may affect the stability of the cellular actin backbone and synaptic structure by influencing the aggregation of α-Synuclein (a-syn). We selected two circRNAs overexpressed in PD patients for validation (hsa_circ_0001535 and hsa_circ_0000437), the results revealed that their expression levels were all reduced to varying degrees (p < 0.05) after rehabilitation. After network analysis, we believe that hsa_circ_0001535 may be related to the aggregation of a-syn, while hsa_circ_0000437 may act on hsa-let-7b-5p or hsa-let-7c-5p through sponge effect to cause inflammatory response. Our findings suggest that rehabilitation can mitigate the pathological process of PD by epigenetic means.
FDC-SP as a diagnostic and prognostic biomarker and modulates immune infiltrates in renal cell carcinoma

Published: December 2022

Abstract
Background
One of the top 10 causes of cancer death, renal cell carcinoma (RCC) accounts for more than 90% of all occurrences of primary renal cancer globally. Follicular dendritic cell-secreted protein (FDC-SP) particularly attaches to activated B cells and controls the production of antibodies. It is also believed to encourage the invasion and migration of cancer cells, which may aid in tumor metastases. The purpose of this study was to evaluate the utility of FDC-SP in the diagnosis and prognosis of RCC and to examine how immune infiltration in RCC relates to it.
Results
FDC-SP mRNA and protein levels were significantly higher in RCC tissues compared to normal tissues. The T stage, histological grade, pathological stage, M stage, OS event, DSS event, and PFI event were all associated with the high expression level of FDC-SP. Immune response regulation, complement, and coagulation were the key pathways that were enriched, according to functional enrichment analysis. The levels of FDC-SP expression were found to be significantly correlated with immune cell infiltration, immunological checkpoints, and therapeutic targets. The prognosis of RCC patients with greater FDC-SP expression levels was worse, and FDC-SP expression levels demonstrated the ability to precisely discriminate tumor tissues from healthy tissues (area under the curve (AUC) = 0.635). The AUC values for one, three, and five-year survival rates were all greater than 0.58. An independent predictive biomarker of OS in RCC patients is FDC-SP expression.
Conclusion
FDC-SP may be a prospective therapeutic target in RCC as well as a possible diagnostic and prognostic biomarker associated with immune infiltration.
Normality and the treatment-enhancement distinction
Authors: Martin Daniel , Rueda Jon , Earp Brian D. , Hannikainen Ivar R. 
Published: December 2022

Abstract
People overwhelmingly recognize patients’ needs for medical care intended to restore cognitive or physical health that has deteriorated below what is considered typical, due to disease or disorder (e.g., psychostimulant medication to sustain attention in the case of attention deficit disorder). When asked whether a healthy individual may undergo the sameintervention for the purpose of exceeding typical functioning, people often express greater hesitation. The present work examines this phenomenon, known as the treatment-enhancement distinction, and builds on prior research in moral philosophy and cognitive science to ask why it might arise. In two experiments, we provide evidence that the accessibility of health-related interventions determines their perceived descriptive normality (Experiment 1), and that gains in descriptive normality of such interventions weaken the moral distinction between treatment and enhancement (Experiment 2). In short, these findings suggest that the treatment-enhancement distinction may be driven, at least in part, by assumptions about descriptive abnormality; and raise the possibility that normalizing novel biomedical interventions by promoting access could alleviate people’s selective opposition toward enhancement, rendering it morally equivalent to treatment.
