Abstract
Aims Free fatty acid receptor 4 (Ffar4) is a receptor for long-chain fatty acids that attenuates heart failure driven by increased afterload. Recent findings suggest that Ffar4 prevents ischemic injury in brain, liver, and kidney, and therefore, we hypothesized that Ffar4 would also attenuate cardiac ischemic injury. Methods and Results Using a mouse model of ischemia-reperfusion (I/R), we found that mice with systemic deletion of Ffar4 (Ffar4KO) demonstrated impaired recovery of left ventricular systolic function post-I/R with no effect on initial infarct size. To identify potential mechanistic explanations for the cardioprotective effects of Ffar4, we performed bulk RNAseq to compare the transcriptomes from wild-type (WT) and Ffar4KO infarcted myocardium 3-days post-I/R. In the Ffar4KO infarcted myocardium, gene ontology (GO) analyses revealed augmentation of glycosaminoglycan synthesis, neutrophil activation, cadherin binding, extracellular matrix, rho signaling, and oxylipin synthesis, but impaired glycolytic and fatty acid metabolism, cardiac repolarization, and phosphodiesterase activity. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis indicated impaired AMPK signaling and augmented cellular senescence in the Ffar4KO infarcted myocardium. Interestingly, phosphodiesterase 6c (PDE6c), which degrades cGMP, was the most upregulated gene in the Ffar4KO heart. Further, the soluble guanylyl cyclase stimulator, vericiguat, failed to increase cGMP in Ffar4KO cardiac myocytes, suggesting increased phosphodiesterase activity. Finally, cardiac myocyte-specific overexpression of Ffar4 prevented systolic dysfunction post-I/R, defining a cardioprotective role of Ffa4 in cardiac myocytes. Conclusions Our results demonstrate that Ffar4 in cardiac myocytes attenuates systolic dysfunction post-I/R, potentially by attenuating oxidative stress, preserving mitochondrial function, and modulation of cGMP signaling.

Abstract
BACKGROUND Rheumatic heart disease is the major cause of valvular heart disease in developing nations. Endothelial cells (ECs) are considered crucial contributors to rheumatic heart disease, but greater insight into their roles in disease progression is needed. METHODS We used a Cdh5-driven EC lineage-tracing approach to identify and track ECs in the K/B.g7 model of autoimmune valvular carditis. Single-cell RNA sequencing was used to characterize the EC populations in control and inflamed mitral valves. Immunostaining and conventional histology were used to evaluate lineage tracing and validate single-cell RNA-sequencing findings. The effects of VEGFR3 (vascular endothelial growth factor receptor 3) and VEGF-C (vascular endothelial growth factor C) inhibitors were tested in vivo. The functional impact of mitral valve disease in the K/B.g7 mouse was evaluated using echocardiography. Finally, to translate our findings, we analyzed valves from human patients with rheumatic heart disease undergoing mitral valve replacements. RESULTS Lineage tracing in K/B.g7 mice revealed new capillary lymphatic vessels arising from valve surface ECs during the progression of disease in K/B.g7 mice. Unsupervised clustering of mitral valve single-cell RNA-sequencing data revealed novel lymphatic valve ECs that express a transcriptional profile distinct from other valve EC populations including the recently identified PROX1 (Prospero homeobox protein 1)+ lymphatic valve ECs. During disease progression, these newly identified lymphatic valve ECs expand and upregulate a profibrotic transcriptional profile. Inhibiting VEGFR3 through multiple approaches prevented expansion of this mitral valve lymphatic network. Echocardiography demonstrated that K/B.g7 mice have left ventricular dysfunction and mitral valve stenosis. Valve lymphatic density increased with age in K/B.g7 mice and correlated with worsened ventricular dysfunction. Importantly, human rheumatic valves contained similar lymphatics in greater numbers than nonrheumatic controls. CONCLUSIONS These studies reveal a novel mode of inflammation-associated, VEGFR3-dependent postnatal lymphangiogenesis in murine autoimmune valvular carditis, with similarities to human rheumatic heart disease.

Abstract
Objective: To investigate the echocardiographic features, consistency of diagnosis between fetal and postnatal periods and postnatal clinical outcomes of fetal pulmonary valve stenosis (PS) with different degrees. Methods: This study was a retrospective cohort study comprising 108 cases of fetal PS diagnosed during the fetal period and followed up postnatally at Xinhua Hospital, Shanghai Jiaotong University School of Medicine from November 2012 to February 2023. Echocardiographic characteristics, including morphological and hemodynamic features were collected for all fetuses who were then were followed up to at least 6 months after birth. One-way analysis of variance and Kruskal-Wallis test were used to compare the differences in the echocardiographic features among fetuses with different degrees of PS. Subsequently, McNemar test was used to assess the consistency of diagnosis between the fetal and postnatal periods. Furthermore, Logistic regression analysis was applied to explore the risk factors for neonatal intervention in fetuses with moderate PS and the receiver operating characteristic (ROC) curve was utilized to ascertain the optimal cut-off value for continuous variables. Results: The age of the mothers of the 108 fetuses at the initial assessment was (30.8±4.0) years, and the gestational age was 26.5 (24.6, 30.0) weeks. The fetuses were categorized into mild (17 cases), moderate (49 cases), and severe groups (42 cases) based on the initial echocardiographic features. Mild PS was characterized by valve thickening and hyperechogenicity combined with systolic flow acceleration or dilation of main pulmonary artery. Moderate PS exhibited both restricted valve motion and a colorful blood flow pattern at the valve orifice. The peak flow velocities of fetuses with moderate and critical PS were notably higher than those in the mild group ((2.66±0.86) and (2.77±1.30) vs. (1.43±0.59)m/s, F=14.52, P<0.001). In critical PS, all cases showed retrograde ductal flow, with a significantly higher proportion of a small right ventricle compared to the mild and moderate PS (42.9% (18/42) vs. 0 and 2.0% (1/49), χ2=31.73, P<0.001). The proportion of severe tricuspid regurgitation was also higher (35.7% (15/42) vs. 0 and 10.2% (5/49), χ2=36.94, P<0.001). Compared to mild and severe PS, the consistency of diagnosis between fetal and postnatal periods in moderate PS was lower (40.8% (20/49) vs.13/17 and 80.3% (35/42), χ2=12.45, P=0.006). The systolic flow velocity was identified as an independent risk factor for neonatal intervention in fetuses with moderate PS (OR=7.21, 95%CI2.11-24.62). A flow velocity of ≥2.18 m/s in second trimester and ≥3.15 m/s in third trimester indicated the necessity of neonatal intervention for fetal moderate PS. Among the 108 fetuses, 68 underwent surgical intervention and all survived. Additionally, 39 fetuses were regularly followed up. A sole non-surgical fatality occurred, leading to a 6-month survival rate of 99.1% (107/108). Conclusions: Various degrees of fetal PS demonstrate distinctive morphological and hemodynamic alterations in echocardiography. The disparity in severity between the postnatal and fetal stages requires ongoing monitoring for fetal PS. The prognosis for fetal PS is generally favorable.

Abstract
Objective: To explore the clinical and imaging features of acute encephalopathy with biphasic seizures and late reduced diffusion(AESD) in children. Methods: For the case series study, 21 children with AESD from Peking University First Hospital, Provincial Children's Hospital Affiliated to Anhui Medical University, Children's Hospital of Fudan University, and Shanxi Children's Hospital who were diagnosed and treated from October 2021 to July 2023 were selected. Clinical data were collected to summarize their clinical information, imaging, and laboratory tests, as well as treatment and prognostic characteristics. Descriptive statistical analysis was applicated. Results: Of the 21 cases with AESD, 11 were males and 10 were females, with the age of onset of 2 years and 6 months (1 year and 7 months, 3 years and 6 months). Of the 21 cases, 18 were typical cases with biphasic seizures. All typical cases had early seizures within 24 hours before or after fever onset. Among them, 16 cases had generalized seizures, 2 cases had focal seizures, and 7 cases reached the status epilepticus. Of the 21 cases, 3 atypical cases had late seizures in biphasic only. The late seizures in the 21 cases occurred on days 3 to 9. The types of late seizures included focal seizures in 12 cases, generalized seizures in 6 cases, and both focal and generalized seizures in 3 cases. Diffusion-weighted imaging (DWI) test on days 3 to 11 showed reduced diffusion of subcortical white matter which was named "bright tree sign" in all cases. The diffuse cerebral atrophy predominantly presented in the front-parietal-temporal lobes was found in 19 cases between day 12 and 3 months after the onset of the disease. Among 21 cases, 20 had been misdiagnosed as autoimmune encephalitis, central nervous system infection, febrile convulsions, posterior reversible encephalopathy syndrome, acute disseminated encephalomyelitis, and hemiconvulsion-hemiplegia-epilepsy syndrome. All the cases received high-dose gammaglobulin and methylprednisolone pulse therapy with poor therapeutic effect. By July 2023, 18 cases were under follow-up. Among them, 17 cases were left with varying degrees of neurologic sequelae, including 11 cases with post-encephalopathic epilepsy; 1 recovered completely. Conclusions: AESD is characterized by biphasic seizures clinically and "bright tree sign" on DWI images. Symptomatic and supportive treatments are recommended. The immunotherapy is ineffective. The prognosis of AESD is poor, with a high incidence of neurological sequelae and a low mortality.

Abstract
BACKGROUND Emerging evidence suggests that atrial myopathy may be the underlying pathophysiology that explains adverse cardiovascular outcomes in heart failure (HF) and atrial fibrillation. Lower left atrial (LA) function (strain) is a key biomarker of atrial myopathy, but murine LA strain has not been described, thus limiting translational investigation. Therefore, the objective of this study was to characterize LA function by speckle-tracking echocardiography in mouse models of atrial myopathy. METHODS We used 3 models of atrial myopathy in wild-type male and female C57Bl6/J mice: (1) aged 16 to 17 months, (2) Ang II (angiotensin II) infusion, and (3) high-fat diet+Nω-nitro-L-arginine methyl ester (HF with preserved ejection fraction, HFpEF). LA reservoir, conduit, and contractile strain were measured using speckle-tracking echocardiography from a modified parasternal long-axis window. Left ventricular systolic and diastolic function, and global longitudinal strain were also measured. Transesophageal rapid atrial pacing was used to induce atrial fibrillation. RESULTS LA reservoir, conduit, and contractile strain were significantly reduced in aged, Ang II and HFpEF mice compared with young controls. There were no sex-based interactions. Left ventricular diastolic function and global longitudinal strain were lower in aged, Ang II and HFpEF, but left ventricular ejection fraction was unchanged. Atrial fibrillation inducibility was low in young mice (5%), moderately higher in aged mice (20%), and high in Ang II (75%) and HFpEF (83%) mice. CONCLUSIONS Using speckle-tracking echocardiography, we observed reduced LA function in established mouse models of atrial myopathy with concurrent atrial fibrillation inducibility, thus providing the field with a timely and clinically relevant platform for understanding the pathophysiology and discovery of novel treatment targets for atrial myopathy.

Abstract
BACKGROUND Recent evidence indicates that abnormal P-wave parameters (PWPs)-ECG markers of atrial myopathy-are associated with incident dementia, independent of atrial fibrillation (AF) and clinical ischemic stroke. However, the mechanisms remain unclear and may include subclinical vascular brain injury. Hence, we evaluated the association of abnormal PWPs with brain MRI correlates of vascular brain injury in the Atherosclerosis Risk in Communities Neurocognitive Study (ARIC-NCS). METHODS ARIC-NCS participants who underwent 3T brain MRI scans in 2011-2013 were included. PWPs were measured from standard 12-lead ECGs. Brain MRI outcomes included cortical infarcts, lacunar infarcts, cerebral microhemorrhages, brain volumes, and white matter disease (WMD) volume. We used weighted multivariable logistic and linear regression to evaluate the associations of abnormal PWPs with brain MRI outcomes. RESULTS Among 1715 participants (mean age, 76.1 years; 61% women; 29% Black), 797 (46%) had ≥1 abnormal PWP. After multivariable adjustment, including adjusting for prevalent AF, abnormal P-wave terminal force in lead V1 (aPTFV1) and prolonged P-wave duration (PPWD) were associated with increased odds of both cortical (OR 1.41; 95% CI, 1.14 to 1.74 and OR 1.30; 95% CI, 1.04 to 1.63, respectively) and lacunar infarcts (OR 1.36; 95% CI, 1.15 to 1.63 and OR 1.37; 95% CI, 1.15 to 1.65, respectively). Advanced interatrial block (aIAB) was associated with higher odds of subcortical microhemorrhage (OR 2.04; 95% CI, 1.36 to 3.06). Other than a significant association between aPTFV1 with lower parietal lobe volume, there were no other significant associations with brain or WMD volume. CONCLUSION In this exploratory analysis of a US community-based cohort, ECG surrogates of atrial myopathy are associated with a higher prevalence of brain infarcts and microhemorrhage, suggesting subclinical vascular brain injury as a possible mechanism underlying the association of atrial myopathy with dementia.

Abstract
Transport of Ca2+ into mitochondria is thought to stimulate the production of ATP, a critical process in the heart's fight or flight response, but excess Ca2+ can trigger cell death. The mitochondrial Ca2+ uniporter complex is the primary route of Ca2+ transport into mitochondria, in which the channel-forming protein MCU and the regulatory protein EMRE are essential for activity. In previous studies, chronic Mcu or Emre deletion differed from acute cardiac Mcu deletion in response to adrenergic stimulation and ischemia/reperfusion (I/R) injury, despite equivalent inactivation of rapid mitochondrial Ca2+ uptake. To explore this discrepancy between chronic and acute loss of uniporter activity, we compared short-term and long-term Emre deletion using a novel conditional cardiac-specific, tamoxifen-inducible mouse model. After short-term Emre deletion (3 weeks post-tamoxifen) in adult mice, cardiac mitochondria were unable to take up Ca2+, had lower basal mitochondrial Ca2+ levels, and displayed attenuated Ca2+-induced ATP production and mPTP opening. Moreover, short-term EMRE loss blunted cardiac response to adrenergic stimulation and improved maintenance of cardiac function in an ex vivo I/R model. We then tested whether the long-term absence of EMRE (3 months post-tamoxifen) in adulthood would lead to distinct outcomes. After long-term Emre deletion, mitochondrial Ca2+ handling and function, as well as cardiac response to adrenergic stimulation, were similarly impaired as in short-term deletion. Interestingly, however, protection from I/R injury was lost in the long-term. These data suggest that several months without uniporter function are insufficient to restore bioenergetic response but are sufficient to restore susceptibility to I/R.

APP/PS1 mice and the age-matched wild-type controls were subjected to 3 behavioral tests: open field, new object recognition, and Morris water maze. Expression of Aβ, APP, CTF, BACE1, IDE, NEP, and LRP1 proteins in the extracted hippocampal tissue was evaluated by Western blotting. The distribution and the quantity of amyloid plaques and the spread of microglia in the hippocampus were determined by immunofluorescence. The contents of Aβ40 and Aβ42 in the hippocampus were assayed and analyzed on Simoa HD-1 analyzer. The proteins interacting with Aβ in the hippocampus of APP/PS1 mice were detected by co-immunoprecipitation. Curcumin significantly reduced motor hyperactivity in the open-field test, improved short-term recognition memory, spatial learning, and reference memory in APP/PS1 mice. In the hippocampus of APP/PS1 mice, curcumin significantly diminished the elevated Aβ levels and inhibited microglia proliferation. At the same time, curcumin had no effect on Aβ production, extracellular enzymatic hydrolysis, and LRP1-mediated outward transport, but enhanced Aβ clearance by activation of the intracellular ubiquitin-proteasome system and related peripheral mechanisms. Thus, curcumin improves the learning and memory abilities of APP/PS1 mice and reduces the pathological accumulation of Aβ in the brain.

Abstract
BACKGROUND Atrial fibrillation (AF) is associated with higher risks of ischemic stroke (IS) and dementia. Whether alterations in left atrial (LA) function or size-atrial myopathy-confound these associations remains unknown. OBJECTIVES The purpose of this study was to examine the association of prevalent and incident AF with ischemic stroke and dementia in the ARIC (Atherosclerosis Risk In Communities) study, adjusting for LA function and size. METHODS Participants at visit 5 (2011-2013) with echocardiographic LA function (reservoir, conduit, contractile strain, and emptying fraction) and size (maximal, minimal volume index) data, and without prevalent stroke or dementia were followed through 2019. For analysis, we used time-varying Cox regression. RESULTS Among 5,458 participants (1,193 with AF, mean age of 76 years) in the stroke analysis and 5,461 participants (1,205 with AF, mean age of 75 years) in the dementia analysis, 209 participants developed ischemic stroke, and 773 developed dementia over 7.1 years (median). In a demographic and risk factor-adjusted model, AF was significantly associated with ischemic stroke (HR, 1.63; 95% CI: 1.11-2.37) and dementia (HR: 1.38, 95% CI: 1.13-1.70). After additionally adjusting for LA reservoir strain, these associations were attenuated and no longer statistically significant (stroke [HR: 1.33, 95% CI: 0.88-2.00], dementia [HR: 1.15, 95% CI: 0.92-1.43]). Associations with ischemic stroke and dementia were also attenuated and not statistically significant after adjustment for LA contractile strain, emptying fraction, and minimal volume index. CONCLUSIONS AF-ischemic stroke and AF-dementia associations were not statistically significant after adjusting for measures of atrial myopathy. This proof-of-concept analysis does not support AF as an independent risk factor for ischemic stroke and dementia.

Abstract
Heart failure with preserved ejection fraction (HFpEF) is a complex clinical syndrome, but a predominant subset of HFpEF patients has metabolic syndrome (MetS). Mechanistically, systemic, nonresolving inflammation associated with MetS might drive HFpEF remodeling. Free fatty acid receptor 4 (Ffar4) is a GPCR for long-chain fatty acids that attenuates metabolic dysfunction and resolves inflammation. Therefore, we hypothesized that Ffar4 would attenuate remodeling in HFpEF secondary to MetS (HFpEF-MetS). To test this hypothesis, mice with systemic deletion of Ffar4 (Ffar4KO) were fed a high-fat/high-sucrose diet with L-NAME in their water to induce HFpEF-MetS. In male Ffar4KO mice, this HFpEF-MetS diet induced similar metabolic deficits but worsened diastolic function and microvascular rarefaction relative to WT mice. Conversely, in female Ffar4KO mice, the diet produced greater obesity but no worsened ventricular remodeling relative to WT mice. In Ffar4KO males, MetS altered the balance of inflammatory oxylipins systemically in HDL and in the heart, decreasing the eicosapentaenoic acid-derived, proresolving oxylipin 18-hydroxyeicosapentaenoic acid (18-HEPE), while increasing the arachidonic acid-derived, proinflammatory oxylipin 12-hydroxyeicosatetraenoic acid (12-HETE). This increased 12-HETE/18-HEPE ratio reflected a more proinflammatory state both systemically and in the heart in male Ffar4KO mice and was associated with increased macrophage numbers in the heart, which in turn correlated with worsened ventricular remodeling. In summary, our data suggest that Ffar4 controls the proinflammatory/proresolving oxylipin balance systemically and in the heart to resolve inflammation and attenuate HFpEF remodeling.

Abstract
The electrophysiological activity of the gastrointestinal tract and the mechanical anti-reflux structure of the gastroesophageal junction are the basis of the anti-reflux function of the stomach. Proximal gastrectomy destroys the mechanical structure and normal electrophysiological channels of the anti-reflux. Therefore, the residual gastric function is disordered. Moreover, gastroesophageal reflux is one of the most serious complications. The emergence of various types of anti-reflux surgery through the mechanism of reconstructing mechanical anti-reflux barrier and establishing buffer zone, and the preservation of, the pacing area and vagus nerve of the stomach, the continuity of the jejunal bowel, the original gastroenteric electrophysiological activity of the gastrointestinal tract, and the physiological function of the pyloric sphincter, are all important measures for gastric conservative operations. There are many types of reconstructive approaches after proximal gastrectomy. The design based on the anti-reflux mechanism and the functional reconstruction of mechanical barrier, and the protection of gastrointestinal electrophysiological activities are important considerations for the selected of reconstructive approaches after proximal gastrectomy. In clinical practice, we should consider the principle of individualization and the safety of radical resection of tumor to select a rational reconstructive approaches after proximal gastrectomy.

Abstract
Objective: The docking and superantigen activity sites of staphylococcal enterotoxin-like W (SElW) and T cell receptor (TCR) were predicted, and its SElW was cloned, expressed and purified. Methods: AlphaFold was used to predict the 3D structure of SElW protein monomers, and the protein models were evaluated with the help of the SAVES online server from ERRAT, Ramachandran plot, and Verify_3D. The ZDOCK server simulates the docking conformation of SElW and TCR, and the amino acid sequences of SElW and other serotype enterotoxins were aligned. The primers were designed to amplify selw, and the fragment was recombined into the pMD18-T vector and sequenced. Then recombinant plasmid pMD18-T was digested with BamHⅠand Hind Ⅲ. The target fragment was recombined into the expression plasmid pET-28a(+). After identification of the recombinant plasmid, the protein expression was induced by isopropyl-beta-D- thiogalactopyranoside. The SElW expressed in the supernatant was purified by affinity chromatography and quantified by the BCA method. Results: The predicted three-dimensional structure showed that the SElW protein was composed of two domains, the amino-terminal and the carboxy-terminal. The amino-terminal domain was composed of 3 α-helices and 6 β-sheets, and the carboxy-terminal domain included 2 α-helices and 7 antiparallel β-sheets composition. The overall quality factor score of the SElW protein model was 98.08, with 93.24% of the amino acids having a Verify_3D score ≥0.2 and no amino acids located in disallowed regions. The docking conformation with the highest score (1 521.328) was selected as the analysis object, and the 19 hydrogen bonds between the corresponding amino acid residues of SElW and TCR were analyzed by PyMOL. Combined with sequence alignment and the published data, this study predicted and found five important superantigen active sites, namely Y18, N19, W55, C88, and C98. The highly purified soluble recombinant protein SElW was obtained with cloning, expression, and protein purification. Conclusions: The study found five superantigen active sites in SElW protein that need special attention and successfully constructed and expressed the SElW protein, which laid the foundation for further exploration of the immune recognition mechanism of SElW.

Abstract
Hemophagocytic syndrome (HPS), which is currently named as hemophagocytic lymphohistiocytosis (HLH), is a hyperinflammatory syndrome characterized by persistent fever, hepatosplenomegaly, pancytopenia and hemophagocytosis found in bone marrow, liver, spleen and lymph nodes due to excessive activation of macrophages and cytotoxic T cells. Macrophage activation syndrome (MAS) is a specific form of HLH induced by autoinflammatory/autoimmune disorders which can be life-threatening and requires multiple disciplines. In order to improve clinicians' understanding of MAS and standardize the clinical diagnosis and treatment practice of MAS, the rheumatology branch of Chinese Rheumatology Association organized domestic experts to formulate the diagnosis and treatment standard, in order to improve the diagnosis and treatment level of MAS and improve the prognosis of patients.

Abstract
BACKGROUND Atrial myopathy-characterized by changes in left atrial function and size-may precede and promote atrial fibrillation (AF) and cardiac thromboembolism. In people without prior AF or stroke, whether analysis of left atrial function and size can improve ischemic stroke prediction is unknown. OBJECTIVE To evaluate the association of echocardiographic left atrial function (reservoir, conduit, and contractile strain) and left atrial size (left atrial volume index) with ischemic stroke and determine whether these measures can improve the stroke prediction achieved by CHA2DS2-VASc score variables. DESIGN Prospective cohort study. SETTING ARIC (Atherosclerosis Risk in Communities) study. PARTICIPANTS 4917 ARIC participants without prevalent stroke or AF. MEASUREMENTS Ischemic stroke events (2011 to 2019) were adjudicated by physicians. Left atrial strain was measured using speckle-tracking echocardiography. RESULTS Over 5 years, the cumulative incidences of ischemic stroke in the lowest quintiles of left atrial reservoir, conduit, and contractile strain were 2.99% (95% CI, 1.89% to 4.09%), 3.18% (CI, 2.14% to 4.22%), and 2.15% (CI, 1.09% to 3.21%), respectively, and that of severe left atrial enlargement was 1.99% (CI, 0.23% to 3.75%). On the basis of the Akaike information criterion, left atrial reservoir strain plus CHA2DS2-VASc variables was the best predictive model. With the addition of left atrial reservoir strain to CHA2DS2-VASc variables, 11.6% of the 112 participants with stroke after 5 years were reclassified to higher risk categories and 1.8% to lower risk categories. Among the 4805 participants who did not develop stroke, 12.2% were reclassified to lower and 12.7% to higher risk categories. Decision curve analysis showed a predicted net benefit of 1.34 per 1000 people at a 5-year risk threshold of 5%. LIMITATION Underascertainment of subclinical AF. CONCLUSION In people without prior AF or stroke, when added to CHA2DS2-VASc variables, left atrial reservoir strain improves stroke prediction and yields a predicted net benefit, as shown by decision curve analysis.

Abstract
A surge in the prevalence of obesity and metabolic syndrome, which promote systemic inflammation, underlies an increase in cardiometabolic disease. Free fatty acid receptor 4 is a nutrient sensor for long-chain fatty acids, like ω3-polyunsaturated fatty acids (ω3-PUFAs), that attenuates metabolic disease and resolves inflammation. Clinical trials indicate ω3-PUFAs are cardioprotective, and this review discusses the mechanistic links between ω3-PUFAs, free fatty acid receptor 4, and attenuation of cardiometabolic disease.

Abstract
With the increasing detection rate of early upper gastric cancer and adenocarcinoma of esophagogastric junction, the safety of proximal gastrectomy with clear indications has been verified, and function-preserving proximal gastrectomy has been widely used. However, proximal gastrectomy destructs the normal anatomical structure of esophagogastric junction, resulting in severe postoperative gastroesophageal reflux symptoms and seriously affecting the quality of life. Among various anti-reflux surgery methods, reconstruction of "cardiac valve" has always been the focus of relevant scholars because its similarity with the mechanism of normal anti-reflux. After years of development, evolution and optimization, the designed seromuscular flap anastomosis includes tunnel muscle flap anastomosis, Hatafuku valvuloplasty, single muscle flap anastomosis and double muscle flap anastomosis. The double muscle flap anastomosis has become a research hotspot because it shows good anti-reflux effect in clinical application. This paper reviews the history, research status and hot issues of seromuscular flap anastomosis of esophageal remnant stomach at home and abroad.

Abstract
IMPORTANCE Atrial myopathy-characterized by alterations in left atrial (LA) function and size-is associated with ischemic stroke, independent of atrial fibrillation (AF). Electrocardiographic markers of atrial myopathy are associated with dementia, but it is unclear whether 2-dimensional echocardiographic (2DE)-defined LA function and size are associated with dementia. OBJECTIVE To examine the association of LA function and size with incident dementia. DESIGN, SETTING, AND PARTICIPANTS The Atherosclerosis Risk in Communities (ARIC) study is a community-based prospective cohort. An exploratory, retrospective analysis was conducted. ARIC centers are located in Forsyth County, North Carolina; Jackson, Mississippi; Washington County, Maryland; and suburban Minneapolis, Minnesota. For this analysis, visit 5 (2011-2013) served as the baseline. Participants without prevalent AF and stroke and who had 2DEs in 2011-2013 were included and surveilled through December 31, 2019. EXPOSURES LA function (reservoir strain, conduit strain, contractile strain, emptying fraction, passive emptying fraction, and active emptying fraction), and LA size (maximal and minimal volume index) as evaluated by 2DE. MAIN OUTCOMES AND MEASURES Dementia cases were identified using in-person and phone cognitive assessments, hospitalization codes, and death certificates. Cox proportional hazards models were used. RESULTS Among 4096 participants (mean [SD] age, 75 [5] years; 60% women; 22% Black individuals), 531 dementia cases were ascertained over a median follow-up of 6 years. Dementia incidence for the lowest LA quintile was 4.80 for reservoir strain, 3.94 for conduit strain, 3.29 for contractile strain, 4.20 for emptying fraction, 3.67 for passive emptying fraction, and 3.27 for active emptying fraction per 100 person-years. After full-model adjustments, there were statistically significant associations between measures of LA function and dementia; the hazard ratios (HRs) from the lowest vs highest quintile for reservoir strain were 1.98 (95% CI, 1.42-2.75); for conduit strain, 1.50 (95% CI, 1.09-2.06); for contractile strain, 1.57 (95% CI, 1.16-2.14); for emptying fraction, 1.87 (95% CI, 1.31-2.65); and for active emptying fraction, 1.43 (95% CI, 1.04-1.96). LA passive emptying fraction was not significantly associated with dementia (HR, 1.26 [95% CI, 0.93-1.71]). Dementia incidence for the highest LA maximal volume index quintile was 3.18 per 100 person-years (HR for highest vs lowest quintile, 0.77 [95% CI, 0.58-1.02]) and for the highest minimal volume index quintile was 3.50 per 100 person-years (HR for the highest vs lowest quintile, 0.95 [95% CI, 0.71-1.28]). Both measures were not significantly associated with dementia. These findings were robust to sensitivity analyses that excluded participants with incident AF or stroke. CONCLUSIONS AND RELEVANCE In this exploratory analysis of a US community-based cohort, several echocardiographic measures of lower LA function were significantly associated with an increased risk of subsequent dementia. Measures of LA size were not significantly associated with dementia risk. These findings suggest that impaired LA function may be a risk factor associated with dementia.

Abstract
Objective: To explore the epidemiological characteristics and treatment outcomes of patients with hydrofluoric acid burns in hands. Methods: A retrospective observational study was conducted. The medical records of 229 patients with hydrofluoric acid burns in hands who were admitted to Zhejiang Quhua Hospital from January 2008 to December 2020 and met the inclusion criteria were collected. The following statistical data of patients were collected, including gender, age, type of affiliated enterprise, hydrofluoric acid mass fraction, injury site, total burn area, prehospital time, length of hospital stay, length of wound healing, whether hypocalcemia and hypomagnesemia occurred or not on admission, whether surgery intervention was performed or not, and whether scar sequelae occurred or not. Single factor and multivariate logistic regression analysis were used to screen out the risk factors impacting surgery intervention and scar sequelae of all the patients and patients whose hydrofluoric acid mass fraction was known. Single factor and multivariate linear regression analysis were used to screen out the risk factors impacting the length of wound healing of all the patients and patients whose hydrofluoric acid mass fraction was known. Results: The 229 patients included 206 males and 23 females, with the majority aged 30 to 50 years (139 patients). The type of affiliated enterprise of majority patients was non-fluorine chemical enterprise. The hydrofluoric acid mass fraction was known in only 91 patients, mainly medium. The majority injury site was in the middle and end of finger. The total burn area was below or equal to 1% total body surface area. The prehospital time was 19 (9, 29) h. The length of hospital stay was 2 (1, 7) d. The length of wound healing was 12 (8, 18) d. The proportions of hypocalcemia and hypomagnesemia were 0.9% (2/229) and 1.3% (3/229) on admission, respectively. Thirty-six patients had surgeries and 83 patients had scar sequelae. In 229 patients, single factor logistic regression analysis showed that both type of affiliated enterprise and prehospital time were the factors impacting surgery intervention (with odds ratio values of 7.86 and 51.35, respectively, 95% confidence intervals of 1.83-33.76 and 11.89-221.78, respectively, P<0.01) and scar sequelae of patients (with odds ratio values of 3.62 and 27.40, respectively, 95% confidence intervals of 1.76-7.43 and 13.25-56.68, respectively, P<0.01); multivariate logistic regression analysis showed that prehospital time was the independent risks factor impacting surgery intervention and scar sequelae of patients (with odds ratio values of 43.00 and 24.55, respectively, 95% confidence intervals of 9.89-187.03 and 11.78-51.16, respectively, P<0.01); single factor linear regression analysis showed that both type of affiliated enterprise and prehospital time were the factors impacting the length of wound healing of patients (with β values of 6.16 and 12.83, respectively, 95% confidence intervals of 3.38-8.93 and 10.72-14.93, respectively, P<0.01); multivariate linear regression analysis showed that both type of affiliated enterprise and prehospital time were the independent risk factors impacting the length of wound healing of patients (with β values of 2.81 and 12.16, respectively, 95% confidence intervals of 0.50-5.13 and 10.00-14.31, respectively, P<0.05 or P<0.01). In 91 patients whose hydrofluoric acid mass fraction was known, single factor logistic regression analysis showed that type of affiliated enterprise, hydrofluoric acid mass fraction (low and high), and prehospital time were all the factors impacting surgery intervention of patients (with odds ratio values of 9.10, 11.25, 10.69, and 0.04, respectively, 95% confidence intervals of 1.15-72.25, 1.39-90.93, 1.32-86.59, and 0.01-0.19, respectively, P<0.05 or P<0.01), type of affiliated enterprise, hydrofluoric acid mass fraction, and prehospital time were all the factors impacting scar sequelae of patients (with odds ratio values of 0.32, 0.21, and 36.80, respectively, 95% confidence intervals of 0.11-0.92, 0.06-0.73, and 11.03-122.79, respectively, P<0.05 or P<0.01); multivariate logistic regression analysis showed that both hydrofluoric acid mass fraction and prehospital time were the independent risk factors impacting surgery intervention of patients (with odds ratio values of 11.51 and 0.04, respectively, 95% confidence intervals of 1.22-108.26 and 0.01-0.25, respectively, P<0.05 or P<0.01), prehospital time was the independent risk factor impacting scar sequelae of patients (odds ratio=37.71, with 95% confidence interval of 9.97-142.69, P<0.01); single factor linear regression analysis showed that type of affiliated enterprise, hydrofluoric acid mass fraction (low and high), and prehospital time were all the factors impacting the length of wound healing of patients (with β values of 7.12, -5.63, -9.74, and 13.50, respectively, 95% confidence intervals of 2.43-11.81, -10.59--0.68, -14.78--4.70, and 10.14-16.86, respectively, P<0.05 or P<0.01); multivariate linear regression analysis showed that both hydrofluoric acid mass fraction and prehospital time were the independent risk factors impacting the length of wound healing of patients (with β values of -5.84 and 0.09, respectively, 95% confidence intervals of -10.59--1.08 and 0.05-0.12, respectively, P<0.05 or P<0.01). Conclusions: The majority of patients with hydrofluoric acid burns in hands are young and middle-aged males. Type of affiliated enterprise, hydrofluoric acid mass fraction and prehospital time are the risk factors that affect the treatment outcomes of patients with hydrofluoric acid burns in hands.

Abstract
Gasdermin E (GSDME), as the major executive protein of pyroptosis, has been considered to be linked to antitumor immunity in recent years. However, the role of GSDME in oral squamous cell carcinoma (OSCC) remains to be elucidated. Here, by using a human OSCC tissue microarray, human OSCC tissue, and Tgfbr1/Pten conditional knockout mice, we found that GSDME was strongly expressed in OSCC and that GSDME expression in primary tumors was higher than that in metastatic lymph nodes. In addition, GSDME expression in OSCC was positively related to better prognosis. Moreover, GSDME-mediated pyroptosis occurred upon stimulation with chemotherapy drugs, and functional knockdown of GSDME attenuated the cisplatin-induced antitumor effect. Consistent with these results, bioinformatic analysis indicated that GSDME expression was positively correlated with the sensitivity of a number of antitumor drugs approved by the US Food and Drug Administration. Inhibition of GSDME expression by small interfering RNA in SCC7 cells significantly increased the expression of the cancer stem cell markers, CD44 and ALDH1. Furthermore, multiplexed immunohistochemistry and flow cytometry indicated that the expression of GSDME positively correlated with tumor-infiltrating CD8+ T cells, granzyme B, and M1 phenotype macrophages. Collectively, these findings demonstrated that GSDME is a potential positive prognostic factor of OSCC, and GSDME-mediated pyroptosis induced by chemotherapy plays a role in antitumor response.

Abstract
The aim of this study is to determine if there is an association between atrial arrhythmias and brain amyloid-β (Aβ), measured on florbetapir (FBP) PET. 346 nondemented participants from the Atherosclerosis Risk in Communities study underwent FBP-PET, 185 also wore Zio® XT Patch. The associations between global cortical Aβ (> 1.2 standardized uptake value ratio) and history of atrial fibrillation, zio-defined atrial tachycardia and premature atrial contractions, each, were evaluated. Among nondemented community-dwelling older adults, we did not find an association between atrial arrhythmias and Aβ. Other brain pathology may underlie the association described between atrial arrhythmias and cognition.

Abstract
Background Black Americans have more atrial fibrillation risk factors but lower atrial fibrillation risk than White Americans. Left atrial (LA) enlargement and/or dysfunction, frequent atrial tachycardia (AT), and premature atrial contractions (PAC) are associated with increased atrial fibrillation risk. Racial differences in these factors may exist that could explain the difference in atrial fibrillation risk. Methods and Results We included 2133 ARIC (Atherosclerosis Risk in Communities) study participants (aged 74±4.5 years[mean±SD], 59% women, 27% Black participants) who had echocardiograms in 2011 to 2013 and wore the Zio XT Patch (a 2-week continuous heart monitor) in 2016 to 2017. Linear regression was used to analyze (1) differences in AT/day or PAC/hour between Black and White participants, (2) differences in LA measures between Black and White participants, and (3) racial differences in the association of LA measures with AT or PAC frequency. Compared with White participants, Black participants had a higher prevalence of cardiovascular risk factors and disease, lower AT frequency, greater LA size, and lower LA function. After multivariable adjustments, Black participants had 37% (95% CI, 24%-47%) fewer AT runs/day than White participants. No difference in PAC between races was noted. Greater LA size and reduced LA function are associated with more AT and PAC runs; however, no race interaction was present. Conclusions Differences in LA measures are unlikely to explain the difference in atrial fibrillation risk between Black and White individuals. Despite more cardiovascular risk factors and greater atrial remodeling, Black participants have lower AT frequency than White participants. Future research is needed to elucidate the protective mechanisms that confer resilience to atrial arrhythmias in Black individuals.

Abstract
Objective: Traditional Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy can greatly decrease the anastomosis-related complications and reduce the incidence of reflux esophagitis, but its complexity limits the wide application. To decrease the complexity of Kamikawa anastomosis, the surgical team of Changzhi People's Hospital of Shanxi Changzhi Medical College improved this technique by using novel notion and reduced surgical procedures. This study aims to evaluate the efficacy and safety of modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy. Methods: A descriptive cohort study was carried out. Case enrollment criteria: (1) upper gastric carcinoma or esophagogastric junction carcinoma without distant metastasis was confirmed by preoperative gastroscopic biopsy and imaging examination; (2) tumor diameter was less than 4 cm; (3) preoperative clinical staging was cT1-3N1M0. Exclusion criteria: (1) patients received preoperative neoadjuvant chemotherapy; (2) patients had severe heart or lung disease, or poor nutritional status so that they could not tolerate surgery. Clinical data of 25 patients with upper gastric carcinoma or esophagogastric junction carcinoma who underwent modified Kamikawa anastomosis in digestive tract reconstruction in Heji Hospital (8 cases) and Changzhi People's Hospital (17 cases) from April 2019 to December 2020 were retrospectively collected. Of 25 patients, 21 were male and 4 were female, with mean age of 63.0 (49 to 78) years; 3 underwent open surgery and 22 underwent laparoscopic surgery. The modified Kamikawa anastomosis was as follows: (1) the novel notion of total mesangial resection of the esophagogastric junction was applied to facilitate the thorough removal of lymph nodes and facilitate hand-sewn anastomosis and embedding; (2) the diameter of the anastomotic stoma was selected according to the diameter of the esophageal stump, between 2.5 and 3.5 cm, to reduce the occurrence of anastomotic stenosis; (3) an ultrasonic scalpel was used to incise the esophageal stump, which could not only prevent bleeding of the esophageal stump, but also closely seal the esophageal mucosa, muscle layer and serosa to prevent esophageal mucosa retraction; (4) barbed suture was used to suture the remnant stomach fundus and esophagus to fix the stomach fundus in order to reduce the cumbersome and difficult intermittent sutures in a small space; (5) two barbed sutures were used to continuously suture the front and back walls of the anastomosis and complete the suture and fixation of the muscle flap. Relevant indicators of surgical safety, postoperative complications (using the Clavien-Dindo classification), esophageal reflux symptoms and the occurrence of esophagitis (using Los Angeles classification) were analyzed. The gastroesophageal reflux disease (GERD) score, gastroscopy, multi-position digestive tract radiography during postoperative follow-up were used to evaluate the residual gastric motility and anti-reflux efficacy. Results: Modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy was successfully performed in 25 patients. The surgical time was (5.8±1.8) hours, the intraoperative blood loss was (89.2±11.8) ml, and the average hospital stay was (13.8±2.9) days. Three cases (12.0%) developed postoperative anastomotic stenosis as Clavien-Dindo grade III and were healed after endoscopic dilation treatment. Postoperative upper gastrointestinal radiography showed 1 case (4.0%) with reflux symptoms as Clavien-Dindo grade I. Gastroscopy showed no signs of reflux esophagitis, and its Los Angeles classification was A grade. No anastomotic bleeding, local infection and death were found in all the patients. At postoperative 6-month of follow-up, GERD score showed no significant difference compared to pre-operation (2.7±0.6 vs. 2.4±1.0, t=-1.495, P=0.148). Conclusion: Modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy is safe and feasible with good anti-reflux efficacy.

Abstract
Objective: To investigate the correlation between serum CCL20 level and disease severity in patients with rheumatoid arthritis (RA). Methods: From July 2018 to July 2019, a cross-sectional study was conducted in the Department of Rheumatology and Immunology, the Third Affiliated Hospital of Southern Medical University. The observation group consisted of 105 outpatients and inpatients diagnosed with RA, while the control group was 90 healthy people with age and gender matched physical examination in the Third Affiliated Hospital of Southern Medical University. According to Steinbroker classification, RA patients were divided into Steinbroker grade 2 group (n=35), Steinbroker grade 3 group (n=38) and steinbroker grade 4 group (n=32); according to DAS28 score, RA patients were divided into remission group (DAS28<2.6)(n=39), mild active group (DAS28 2.6-3.2)(n=25), moderate active stage group (DAS28 3.2-5.1)(n=20) and severe active stage group (DAS28 ≥ 5.1)(n=21). The levels of chemokine ligand 20 (CCL20), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were detected by ELISA. The levels of CCL20 in each group were compared, and the correlation between CCL20 and other indicators was analyzed. The receiver operating characteristic (ROC) curve of CCL20 in diagnosis of RA was analyzed to explore the correlation between CCL20 and disease severity of RA patients. Results: Compared with the normal control group, the serum CCL20 level in RA patients was significantly increased [(48.1±16.7) pg/ml vs (17.6±5.9) pg/ml, t=19.39, P<0.001]. In addition, serum CCL20 in steinbroker grade 4 group was significantly higher than that in Steinbroker grade 3 group [(59.5±10.1) pg/ml vs (47.4±17.5) pg/ml, t=3.472, P<0.001], and the serum CCL20 level in steinbroker grade 3 group was significantly higher than that in steinbroker grade 2 group [(47.4±17.5) pg/ml vs (38.4±14.6) pg/ml, t=2.370, P<0.001], CCL20 level in steinbroker grade 2 group was significantly higher than that in normal control group [(38.4±14.6) pg/ml vs (17.6±5.9) pg/ml, t=7.738, P<0.001]. In addition, serum CCL20 level was significantly positively correlated with steinbroker score (r=0.505, P<0.001); CCL20 level in active RA patients was significantly higher than that in remission RA patients [(57.2±13.2) pg/ml vs (32.7±8.9) pg/ml, t=10.31, P<0.001]. The serum CCL20 level in severe activity group was significantly higher than that in moderate activity group [(60.6±10.9) pg/ml vs (51.7±16.2) pg/ml, t=0.212, P=0.040], and the serum CCL20 level in moderate activity group was significantly higher than that in mild activity group [(51.7±16.2) pg/ml vs (40.5±18.6) pg/ml, t=0.217, P=0.037]. In addition, there was a significant positive correlation between serum CCL20 level and DAS28 score (r=0.451, P<0.001). In addition, serum CCL20 level was positively correlated with serum CRP (r=0.332, P<0.001). According to the ROC curve, the specificity of steinbroker grade 2 group was 0.53, and the sensitivity was 0.74, AUC was 0.659; the sensitivity of steinbroker grade 3 group was 0.78, and the specificity was 0.69, AUC was 0.734; the sensitivity of mild vs medium stage was 0.64, and the specificity was 0.70, AUC was 0.699; the sensitivity of medium stage vs severe stage was 0.57, and the specificity was 0.68,AUC was 0.678. Conclusion: Serum CCL20 level in RA patients is significantly increased and positively correlated with disease severity, which may be used as a marker to observe and evaluate the progression of RA.

Abstract
Objective: To analyze the HIV positive detection rate from different detection channels in Chinese medical institutions. Methods: A Meta-analysis was conducted. First of all, the literature on HIV testing of medical institutions in China was systematically searched on China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, VIP Information Chinese journal Service platform and PubMed. Secondly, a self-made information table was used to collect the basic information, HIV positive number and test number of the literature. Finally, R 4.0.2 software was used to calculate the pooled HIV detection rate and 95%CI of the whole population, detection approaches subgroups and regions subgroups, and then the forest map was drawn. Funnel plot was used to analyze publication bias. Results: A total of 45 studies which covered 22 provinces. Meta analysis showed that the pooled HIV positive rate was 0.82‰ (95%CI: 0.62‰-1.04‰). Subgroup analysis showed that the HIV positive rate of STD outpatient was the highest (3.01‰ (95%CI: 1.76‰-4.58‰), followed by other patients (1.43‰ (95%CI: 1.00‰-1.93‰)). The HIV positive rate of western China was the highest (1.14‰ (95%CI: 0.72‰-1.63‰)). The HIV positive rate in 2008-2017 was higher than in 2000-2007. The Egger test indicated no publication bias (t=-0.737, P=0.465). Conclusion: The HIV positive detection rate of patients in medical institutions in China was at a low level, but the positive rate of patients in STD clinics was relatively high. Therefore, the HIV testing should be further expanded in this population. Secondly, HIV screening should be strengthened for other patients.

Abstract
Ischemic injury initiates a sterile inflammatory response that ultimately participates in the repair and recovery of tissue perfusion. Macrophages are required for perfusion recovery during ischemia, in part because they produce growth factors that aid in vascular remodeling. The input signals governing this pro-revascularization phenotype remain of interest. Here we found that hindlimb ischemia increases levels of resolvin D1 (RvD1), an inflammation-resolving lipid mediator that targets macrophages via its receptor, ALX/FPR2. Exogenous RvD1 enhances perfusion recovery during ischemia, and mice deficient in Alx/Fpr2 have an endogenous defect in this process. Mechanistically, RNA sequencing revealed that RvD1 induces a transcriptional program in macrophages characteristic of a pro-revascularization phenotype. Vascularization of ischemic skeletal muscle, as well as cutaneous wounds, is impaired in mice with myeloid-specific deficiency of Alx/Fpr2, and this is associated with altered expression of pro-revascularization genes in skeletal muscle and macrophages isolated from skeletal muscle. Collectively, these results uncover a role of ALX/FPR2 in revascularization that may be amenable to therapeutic targeting in diseases associated with altered tissue perfusion and repair.

Abstract
Background Atrial fibrillation (AF) is associated with cognitive decline. Whether left atrial enlargement (LAE), a critical substrate for AF, is also associated is less well established. Therefore, we assessed the association of LAE and AF with cognitive decline in the ARIC-NCS (Atherosclerosis Risk in Communities Neurocognitive Study). Methods and Results Participants (n=3391; mean age, 75±5 years; 59% women) underwent cognitive tests and 2-dimensional echocardiograms at visit 5 (2011-2013) and follow-up cognitive tests at visit 6 (2016-2017). LAE was defined as left atrium volume index ≥34 mL/m2. AF was ascertained using study ECGs and hospitalization discharge codes. We assessed the association of AF and LAE with (a) cognitive domain scores at visit 5 and (b) cognitive domain score changes between visit 5 and visit 6. At visit 5, compared with the reference group (without AF, normal left atrium), participants with LAE and AF had significantly lower global cognition (Z score, -0.24; 95% CI, -0.38 to -0.10), whereas participants with AF and without LAE and participants with LAE and without AF did not have lower global cognition. In longitudinal analysis, compared with the reference group, participants with AF but without LAE had significantly greater decline in global cognition (Z score, -0.13; 95% CI, -0.21 to -0.06). However, LAE, with or without AF, was not associated with greater cognitive decline. Conclusion Although LAE with AF was significantly associated with lower cognitive function in cross-sectional analysis, LAE, with or without AF, was not associated with greater cognitive decline over 5 years, highlighting the importance of evaluating longitudinal cognitive function. Future studies should have longer follow-up and evaluate left atrium function.

Abstract
Objective: To investigate and analyze the actual intake of protein and energy in adult patients with severe burns during post burn days (PBDs) 3 to 14. Methods: Records of 52 adult patients with severe burns [37 males and 15 females, (37±9) years old], admitted to the Department of Plastic Surgery and Burns of Tianjin First Central Hospital from January 1st 2011 to December 31st 2017 and meeting the study inclusion criteria, were retrospectively analyzed. Nutrition intake from routes of oral diet, enteral nutrition preparations, and parenteral nutrition preparations of patients during PBDs 3 to 14 were obtained from critical care records. During PBDs 3 to 7 and PBDs 8 to 14, the personal daily total energy intake and the ratio of it to energy target of patients were calculated and compared; the personal daily intake of carbohydrate, fat, and protein and calorigenic percentages of carbohydrate, fat, and protein accounted for total energy intake, and the ratios of non-protein calories to total nitrogen of patients were calculated and compared; the personal daily energy and protein intake of patients from routes of oral diet, enteral nutrition preparations, and parenteral nutrition preparations were analyzed; the percentages of energy intake from routes of oral diet, enteral nutrition preparations, and parenteral nutrition preparations accounted for total energy intake, and the percentages of protein intake from routes of oral diet, enteral nutrition preparations, and parenteral nutrition preparations accounted for total protein intake of patients were calculated. Vomiting and diarrhea of patients during PBDs 3 to 7 and PBDs 8 to 14 were recorded. Levels of serum albumin, prealbumin, blood glucose, and triglycerides, 24-hour excretion of urinary nitrogen, nitrogen balance values of patients on PBDs 7 and 14 were recorded or calculated. Data were processed with paired t test and chi-square test. Results: (1) The personal daily total energy intake of patients during PBDs 3 to 7 and PBDs 8 to 14 were (8 696±573) and (11 980±1 259) kJ respectively, and ratios of them to energy target [(13 290±1 561) kJ] were 65.4% and 90.1% respectively. The personal daily total energy intake of patients during PBDs 3 to 7 was obviously lower than that during PBDs 8 to 14 (t=18.172, P<0.01). (2) The personal daily intake of carbohydrate, fat, and protein of patients during PBDs 8 to 14 were obviously higher than those during PBDs 3 to 7 (t=15.628, 22.231, 10.403, P<0.01). The personal daily calorigenic percentages of carbohydrate, fat, and protein accounted for total energy intake of patients were 56.8%, 25.1%, and 18.3% respectively during PBDs 3 to 7 and 54.2%, 27.0%, and 18.7% respectively during PBDs 8 to 14. The calorigenic constituent ratio of personal daily intake of carbohydrate, fat, and protein accounted for total energy intake of patients during PBDs 3 to 7 was close to that during PBDs 8 to 14 (χ(2)=0.185, P>0.05). The ratios of non-protein calories to total nitrogen (kJ∶g) of patients during PBDs 3 to 7 and PBDs 8 to 14 were 469∶ 1 and 456∶ 1 respectively. (3) The personal daily energy intake of patients from routes of oral diet and parenteral nutrition preparations during PBDs 8 to 14 [(4 394±978), (5 723±898) kJ] were obviously higher than those during PBDs 3 to 7 [(2 137±453), (4 855±825) kJ, t=26.516, 6.583, P<0.01], while the personal daily energy intake of patients from routes of enteral nutrition preparations during PBDs 8 to 14 was close to that during PBDs 3 to 7 (t=1.922, P>0.05). The constituent ratio of personal daily energy during PBDs 3 to 7 was close to that during PBDs 8 to 14 (χ(2)=4.100, P>0.05). The personal daily protein intake of patients from route of oral diet during PBDs 8 to 14 was (58±22) g, obviously higher than (25±6) g during PBDs 3 to 7 (t=14.514, P<0.01). The personal daily protein intake of patients from routes of enteral nutrition preparations and parenteral nutrition preparations during PBDs 8 to 14 was close to those during PBDs 3 to 7 (t=1.924, 1.110, P>0.05). The constituent ratio of personal daily protein intake from routes of oral diet, enteral nutrition preparations, and parenteral nutrition preparations accounted for total protein intake during PBDs 8 to 14 was close to that during PBDs 3 to 7 (χ(2)=5.634, P>0.05). (4) There were 3 patients with vomiting and 4 patients with diarrhea during PBDs 3 to 7, and 1 patient experienced both of them during PBDs 8 to 14. The levels of serum albumin, prealbumin, blood glucose, and triglycerides, 24-hour excretion of urinary nitrogen, and nitrogen balance values of patients on PBDs 7 and 14 were (29±4) and (30±4) g/L, (132±42) and (171±48) mg/L, (7.4±2.8) and (6.7±2.8) mmol/L, (1.5±0.7) and (1.4±0.7) mmol/L, (30.5±4.3) and (34.5±2.2) g, -(25.1±2.6) and -(23.7±3.9) g, respectively. Conclusions: The personal daily total energy intake of patients during PBDs 3 to 7 was lower than that during PBDs 8 to 14. The calorigenic constituent ratio of personal daily intake of carbohydrate, fat, and protein accounted for total energy of patients during PBDs 3 to 7 was close to that during PBDs 8 to 14. Energy and protein intake were mostly derived from parenteral nutrition preparations during PBDs 3 to 7, while those during PBDs 8 to 14 were mainly derived from parenteral nutrition preparations and oral diet.

Abstract
Gendicine (recombinant human p53 adenovirus), developed by Shenzhen SiBiono GeneTech Co. Ltd., was approved in 2003 by the China Food and Drug Administration (CFDA) as a first-in-class gene therapy product to treat head and neck cancer, and entered the commercial market in 2004. Gendicine is a biological therapy that is delivered via minimally invasive intratumoral injection, as well as by intracavity or intravascular infusion. The wild-type (wt) p53 protein expressed by Gendicine-transduced cells is a tumor suppressor that is activated by cellular stress, and mediates cell-cycle arrest and DNA repair, or induces apoptosis, senescence, and/or autophagy, depending upon cellular stress conditions. Based on 12 years of commercial use in >30,000 patients, and >30 published clinical studies, Gendicine has exhibited an exemplary safety record, and when combined with chemotherapy and radiotherapy has demonstrated significantly higher response rates than for standard therapies alone. In addition to head and neck cancer, Gendicine has been successfully applied to treat various other cancer types and different stages of disease. Thirteen published studies that include long-term survival data showed that Gendicine combination regimens yield progression-free survival times that are significantly longer than standard therapies alone. Although the p53 gene is mutated in >50% of all human cancers, p53 mutation status did not significantly influence efficacy outcomes and long-term survival rate for Ad-p53-treated patients. To date, Shenzhen SiBiono GeneTech has manufactured 41 batches of Gendicine in compliance with CFDA QC/QA requirements, and 169,571 vials (1.0 × 1012 vector particles per vial) have been used to treat patients. No serious adverse events have been reported, except for vector-associated transient fever, which occurred in 50-60% of patients and persisted for only a few hours. The manufacturing accomplishments and clinical experience with Gendicine, as well as the understanding of its cellular mechanisms of action and implications, could provide valuable insights for the international gene therapy community and add valuable data to promote further developments and advancements in the gene therapy field.

Abstract
Objective:To analyze the characteristics of patients with benign paroxysmal positional vertigo which were spontaneously cured. Method: A total of 1 257 patients with chief complaint of positional vertigo were included and analyzed retrospectively, in which 921 cases were diagnosed as BPPV with the diagnosis standard of Guiyang meeting, and the other 336 cases were negative in the positional test diagnosed as BPPV-spontaneously cured. The age,gender and history course of the two groups were analyzed respectively.Result:①Among the 1 257 cases of BPPV, 336 (111 male and 225 female) were diagnosed as BPPV-spontaneously cured, with total self remission rate of 26.7%. And the female self remission rate is lower than men slightly(25.9% vs 28.5%).②The ratio of male to female was 1∶2 in patients with BPPV-spontaneously cured and 1∶2.3 in patients with BPPV. Patients of the two groups were mostly female, and there was no significant difference in gender distribution. ③There was no significant difference in age distribution between patients of BPPV-spontaneously cured and BPPV, and patients of >50-70 years old were common in both groups.④The history course of patients in BPPV-spontaneously cured and BPPV both were mostly within 2 weeks at their first visit to hospital,each accounting for 75.3% and 69.3%.But the ratio of patients with BPPV-spontaneously cured for 1-2 weeks was higher than that of the BPPV (20.5% vs 15.1%), and the difference was statistically significant.Conclusion:Whether patients with BPPV can cure spontaneously is not related to age or gender, while women may have a tendency of lower self remission rate. The natural course of patients with BPPV-spontaneously cured is mostly within 2-4 weeks. The duration of natural course may be related to the type of semicircular canal involved.

Abstract
Objective: To produce latent membrane protein 2A (LMP2A) chimeric antigen receptor (CAR)-T cells and detect the lethal effect of LMP2A CAR-T cells on nasopharyngeal carcinoma (NPC) cells. Methods: The study was conducted from September 2016 to December 2017.Genetic engineering technology was used to construct anti-LMP2A CAR lentiviral expression vector and sequencing was identified. The expression of anti-LMP2A CAR in the 293T cells was confirmed by western blot. CCK8 assay was used to evaluate the cytotoxicity of LMP2A CAR-T cells to NPC cells. ELISA assay was performed to test IL-2 and IFN-γ releasing of activated LMP2A CAR-T cells. The inhibition effect of LMP2A CAR-T cells on NPC xenograft tumor was observed in vivo. Statistical analysis was performed by statistical software SPSS 21.0. Results: The results of PCR and sequencing showed that anti-LMP2A CAR lentiviral expression vector was constructed successfully. The result of western blot indicated the expression of anti-LMP2A CAR in the 293T cells effectively. The results of CCK-8 assay showed that the killing activities of LMP2A CAR-T cells to LV-LMP2A-CNE1 cells were (72.11±9.75)%, (54.65 ±5.42)% and (36.68±3.80)% at 20∶1, 10∶1 and 5∶1 ratio of effective cells to target cells, and had a statistical difference compared to CD19 CAR-T cells and T cells (P<0.05). There was no significant difference in the killing activities of LMP2A CAR-T cells to CNE1 cells compared with CD19 CAR-T cells and T cells. The results of ELISA showed that the content of IL-2 and IFN-γ in the co-culture supernatant of LMP2A CAR-T cells and LV-LMP2A-CNE1 cells was significantly higher than that of LMP2A CAR-T cells and CNE1 cells which had statistical difference (P<0.05); In vivo experiment, the volume of LMP2A CAR-T cell group was (80.3±10.0) mm(3) which was significantly lower than that of the control groups, and the difference was statistically significant (P<0.05). Conclusion: LMP2A CAR-T cells are successfully prepared and have an obvious targeting cytotoxicity on LMP2A-positive NPC cells.

Abstract
Zinc is one of the essential trace elements in human body, which plays an important role in regulating acute inflammatory response, glucose metabolism, anti-oxidation, immune and gastrointestinal function of patients with severe burns. Patients with severe burns may suffer from zinc deficiency because of insufficient amount of zinc intake from the diet and a large amount of zinc lose through wounds and urine. Zinc deficiency may affect their wound healing process and prognosis. This article reviews the characteristics of zinc metabolism in patients with severe burns through dynamic monitoring the plasma and urinary concentration of zinc. An adequate dosage of zinc supplemented to patients with severe burns by an appropriate method can increase the level of zinc in plasma and skin tissue and improve wound healing, as well as reduce the infection rates and mortality. At the same time, it is important to observe the symptoms and signs of nausea, dizziness, leukopenia and arrhythmia in patients with severe burns after supplementing excessive zinc.

Abstract
A drifting model for the resonant frequency and retardation amplitude of a photo-elastic modulator (PEM) in the photo-elastic modulated Fourier transform spectrometer (PEM-FTs) is presented. A multi-parameter broadband-matching driving control method is proposed to improve the thermal stability of the PEM interferometer. The automatically frequency-modulated technology of the driving signal based on digital phase-locked technology is used to track the PEM's changing resonant frequency. Simultaneously the maximum optical-path-difference of a laser's interferogram is measured to adjust the amplitude of the PEM's driving signal so that the spectral resolution is stable. In the experiment, the multi-parameter broadband-matching control method is applied to the driving control system of the PEM-FTs. Control of resonant frequency and retardation amplitude stabilizes the maximum optical-path-difference to approximately 236 μm and results in a spectral resolution of 42 cm-1. This corresponds to a relative error smaller than 2.16% (4.28 standard deviation). The experiment shows that the method can effectively stabilize the spectral resolution of the PEM-FTs.

Abstract
BACKGROUND Resolvins are lipid mediators generated by leukocytes during the resolution phase of inflammation. They have been shown to regulate the transition from inflammation to tissue repair; however, it is unknown whether resolvins play a role in tissue revascularization following ischemia. METHODS We used a murine model of hind limb ischemia (HLI), coupled with laser Doppler perfusion imaging, microcomputed tomography, and targeted mass spectrometry, to assess the role of resolvins in revascularization and inflammation resolution. RESULTS In mice undergoing HLI, we identified resolvin D2 (RvD2) in bone marrow and skeletal muscle by mass spectrometry (n=4-7 per group). We also identified RvD2 in skeletal muscle biopsies from humans with peripheral artery disease. Monocytes were recruited to skeletal muscle during HLI and isolated monocytes produced RvD2 in a lipoxygenase-dependent manner. Exogenous RvD2 enhanced perfusion recovery in HLI and microcomputed tomography of limb vasculature revealed greater volume, with evidence of tortuous arterioles indicative of arteriogenesis (n=6-8 per group). Unlike other treatment strategies for therapeutic revascularization that exacerbate inflammation, RvD2 did not increase vascular permeability, but reduced neutrophil accumulation and the plasma levels of tumor necrosis factor-α and granulocyte macrophage colony-stimulating factor. In mice treated with RvD2, histopathologic analysis of skeletal muscle of ischemic limbs showed more regenerating myocytes with centrally located nuclei. RvD2 enhanced endothelial cell migration in a Rac-dependent manner, via its receptor, GPR18, and Gpr18-deficient mice had an endogenous defect in perfusion recovery following HLI. Importantly, RvD2 rescued defective revascularization in diabetic mice. CONCLUSIONS RvD2 stimulates arteriogenic revascularization during HLI, suggesting that resolvins may be a novel class of mediators that both resolve inflammation and promote arteriogenesis.

Abstract
Toxoplasma gondii is one of the most common protozoan parasites with widespread distribution globally. However, little information is available about the seroprevalence of T. gondii infection in geese (Anser domestica) in China. In the present study, the seroprevalence of T. gondii in geese were investigated in Hunan province, China. A total of 900 serum samples were collected from ten administrative regions in Hunan province, China, and assayed for T. gondii antibodies by Indirect Haemagglutination (IHA) test. Overall, 21.1% of the animals were positive for T. gondii antibodies. The results of the present survey indicated the presence of T. gondii infection in geese in Hunan province, China. Therefore, it is important to execute integrated control strategies and measures to prevent and control T. gondii infection in geese in this province. This is the first report seroprevalence of T. gondii in geese in Hunan province, China.

Abstract
Recent studies have indicated that single nucleotide polymorphisms (SNPs) within the 8q24 region may be a risk factor for prostate cancer (PCa). Here, we performed a meta-analysis to evaluate the association between the 8q24 rs6983267 T/G polymorphism and PCa risk. A systematic literature search was carried out in multiple electronic databases independently by two investigators. Pooled odds ratios (ORs) and 95% confidence intervals for 8q24 rs6983267 T/G and PCa were calculated using a fixed-effect model (the Mantel-Haenszel method). In total, 24 case-control studies from 19 articles were included in our meta-analysis. Our analysis indicated that there is a significant PCa risk associated with the rs6983267 polymorphism in a dominant model (GG vs GT+TT, pooled OR = 1.298, P < 0.001); recessive model (GG+GT vs TT, pooled OR = 1.302, P < 0.001); and homozygote comparison (GG vs TT, pooled OR = 1.494, P < 0.001). Similarly, in a subgroup analysis of European and Asian descent, our results revealed that there are associations between rs6983267 T/G polymorphism and PCa susceptibility with the dominant model (GG vs GT+TT), recessive model (GG+GT vs TT), and homozygote comparison (GG vs TT). To investigate the association between rs6983267 and risk of PCa under different clinical conditions, further analyses were conducted regarding different clinical characteristics including the Gleason score, tumor stage, and PSA level to provide a more comprehensive view of PCa risk and this SNP. Publication bias was assed using the Begg test and the Egger test, and none was detected.

Abstract
TUSC3 interacts with the protein phosphatase 1 and magnesium ion transport system, which plays an important role in learning and memory. Abnormal conditions of learning and memory are common clinical characteristics of mental retardation (MR). However, the association of TUSC3 genetic polymorphisms with MR remains unknown. A total of 456 DNA samples including 174 nuclear families containing MR were collected in the Qinba mountain area of China. The genotypes of eight tag single nucleotide polymorphisms of TUSC3 were evaluated with traditional genetic methods. Family-based association tests, transmission disequilibrium tests (TDTs), and haplotype relative risk (HRR) analyses were performed to investigate the association between genetic variants of the TUSC3 gene and MR. The genetic polymorphisms rs10093881, rs6530893, and rs6994908 were associated with MR (all P values <0.05) based upon the results of single-site TDT and HRR analyses. The haplotype block consisting of rs6530893 and rs6994908, harboring the sixth exon of TUSC3, was also associated with MR (all P values <0.05). This study demonstrated an association between genetic polymorphisms of the TUSC3 gene and MR in the Qinba mountain area, the sixth exon of which might contribute to the risk of MR. However, further studies are needed on the causal mechanisms in this association.

Abstract
Non-syndromic cleft of the lip and/or palate (NSCLP) is a very common birth defect; the poliovirus receptor-like 1 gene (PVRL1) has been identified as a genetic risk factor for NSCLP in patients from Norway, the Philippines, and South America. Given the considerable variation in allele frequencies across these geographical regions, this study explored the relationship between NSCLP and mutations of PVRL1 in patients from Guangdong, China. We recruited 171 NSCLP patients and 100 volunteers, and divided our samples into 2 groups: a sequencing group and a mass spectrometry group. In the sequencing group, we screened for mutations in exons 2 and 5 of PVRL1 by polymerase chain reaction and direct sequencing in 71 NSCLP patients and 100 volunteers. In the mass spectrometry group, we screened for amino acid mutations in α-spliced transcript codons 112, 131, and 395, and in the β-spliced transcript codon 1082 using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis in 100 NSCLP patients and 100 volunteers. No mutations were detected in either PVRL1 exons 2 or 5 in the 71 NSCLP patients and 100 volunteers, nor did we find mutations of α-spliced transcript codons 112, 131, 395 and the β-spliced transcript codon 1082 in any of the 100 NSCLP patients and 100 volunteers. Thus, mutations in exons 2 and 5 of PVRL1, and T334A, A391T, G1183A in the α-spliced transcript, and G1082T in the β-spliced transcript do not participate in the development of NSCLP in patients from Guangdong.

Abstract
The genetic diversity of 51 upland cotton cultivars with different parental origins and breeding periods that were developed in Hubei Province was studied on the basis of 237 mapped simple sequence repeat markers covering the cotton genome. A total of 108 polymorphic primer pairs amplified 196 loci; the polymorphism information content range was 0.04 to 0.83, with an average of 0.46. A model-based clustering analysis (STRUCTURE) of the genomic data identified 3 clear subpopulations, and the result was confirmed by principal components analysis. The genetic similarity coefficient among 51 upland cotton cultivars was 0.598 on average, ranging from 0.378 to 0.817. The unweighted pair group method with arithmetic average cluster analysis revealed inconsistencies in other clustering patterns: "Tianmian1" was distinct from the rest of the materials and formed a separate cluster. This study will provide a guide for breeders to develop new cultivars efficiently and to choose parents, and it supports the need to introduce new alleles into the gene pool of the upland cotton breeding program in Hubei Province.

Abstract
FGD1 encoding a guanine nucleotide exchange factor, specifically activates Rho GTPase cell division cycle 42 (Cdc42). Dysfunction of FGD1 causes Aarskog-Scott syndrome (MIM #305400), an X-linked disorder that may affect bone and intellectual development. However, the relationship between FGD1 and intellectual developmental disorders (IDD) remains unclear. The purpose of this study was to investigate the genetic association between the FGD1 polymorphism and IDD. Working with families from the Qinba mountain area where the occurrence of IDD is higher than the average in China, we analyzed 456 samples from 130 nuclear families, effectively controlling for stratification and environmental factors. Five SNP loci (rs2230265, rs7881608, rs2239809, rs6614244, and rs2284710) were selected that were well distributed within the FGD1 gene. Genotyping was performed through single-strand conformation polymorphism and restriction fragment length polymorphism. The data were analyzed with transmission disequilibrium tests. In the Qinba mountain area, no significant association was observed between IDD and allele or genotype frequencies, or the haplotype of the 5 SNP loci of the FGD1 gene. The results indicate that FGD1 may not be a monogenetic X-linked factor in IDD. Further studies are required to investigate its role in intellectual development based on its specific interactions with Cdc42 or other partner proteins contributing to IDD.
