Abstract
INTRODUCTION The coronavirus disease 2019 (COVID-19) pandemic has caused extensive disruption of public health worldwide. There were reports of COVID-19 patients having multiple complications. This study investigated COVID-19 from a genetic perspective. METHODS We conducted RNA sequencing (RNA-Seq) analysis of respiratory tract samples from 24 patients with COVID-19. Eight patients receiving mechanical ventilation or extracorporeal membrane oxygenation were regarded as severe cases; the remaining 16 patients were regarded as non-severe cases. After quality control, statistical analyses were performed by logistic regression and the Kolmogorov-Smirnov test to identify genes associated with disease severity. RESULTS Six genes were associated with COVID-19 severity in both statistical tests, namely RPL15, BACE1-AS, CEPT1, EIF4G1, TMEM91, and TBCK. Among these genes, RPL15 and EIF4G1 played roles in the regulation of mRNA translation. Gene ontology analysis showed that the differentially expressed genes were mainly involved in nervous system diseases. CONCLUSION RNA sequencing analysis showed that severe acute respiratory syndrome coronavirus 2 infection is associated with the overexpression of genes involved in nervous system disorders.

Abstract
INTRODUCTION The utilisation of extracorporeal membrane oxygenation (ECMO) has been rapidly increasing in Hong Kong. This study examined 10-year trends in the utilisation and clinical outcomes of ECMO in Hong Kong. METHODS We retrospectively reviewed the records of all adult patients receiving ECMO who were admitted to the intensive care units (ICUs) of public hospitals in Hong Kong between 2010 and 2019. Temporal trends across years were assessed using the Mann-Kendall test. Observed hospital mortality was compared with the Acute Physiology and Chronic Health Evaluation (APACHE) IV-predicted mortality. RESULTS The annual number of patients receiving ECMO increased from 18 to 171 over 10 years. In total, 911 patients received ECMO during the study period: 297 (32.6%) received veno-arterial ECMO, 450 (49.4%) received veno-venous ECMO, and 164 (18.0%) received extracorporeal cardiopulmonary resuscitation. The annual number of patients aged ≥65 years increased from 0 to 47 (27.5%) [P for trend=0.001]. The median (interquartile range) Charlson Comorbidity Index increased from 1 (0-1) to 2 (1-3) [P for trend<0.001] while the median (interquartile range) APACHE IV score increased from 90 (57-112) to 105 (77-137) [P for trend=0.003]. The overall standardised mortality ratio comparing hospital mortality with APACHE IV-predicted mortality was 1.11 (95% confidence interval=1.01-1.22). Hospital and ICU length of stay both significantly decreased (P for trend=0.011 and <0.001, respectively). CONCLUSION As ECMO utilisation increased in Hong Kong, patients put on ECMO were older, more critically ill, and had more co-morbidities. It is important to combine service expansion with adequate resource allocation and training to maintain quality of care.

Abstract
OBJECTIVE Nucleotide excision repair (NER) has been associated with various types of malignant tumors. However, the precise roles of nucleotide excision repair-related genes (NERGs) in acute myeloid leukemia (AML) remain incompletely understood. Hence, this study aimed to develop a prognostic signature incorporating NERGs in AML, which could potentially predict patient outcomes. MATERIALS AND METHODS By querying the Genotype-Tissue Expression (GTEx), The Cancer Genome Atlas (TCGA), and Gene Expression Omnibus (GEO) databases, we acquired RNA-seq data and clinical information pertaining to AML. To identify differentially expressed NERGs (DE-NERGs), we employed the Wilcoxon rank-sum test. Based on the expression patterns of DE-NERGs with prognostic significance, patients were categorized into two subgroups. A prognostic signature was developed through univariate Cox regression and least absolute shrinkage and selection operator (LASSO) analyses to compare the differentially expressed genes (DEGs) between these two groups. Additionally, a nomogram was constructed using multivariate analysis. The biological pathways involved were elucidated through Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, gene set variation analysis (GSVA), and gene set enrichment analysis (GSEA). RESULTS We developed a prognostic model based on an 11-gene signature. Furthermore, the risk score derived from this model was demonstrated to independently serve as a prognostic marker for patients diagnosed with AML. CONCLUSIONS Our prognostic model, based on NERGs, was developed and validated to provide insights into the onset and progression of AML and establish a foundation for more effective treatment. Our findings not only contribute to clinical decision-making but also underscore the significance of nucleotide excision repair. Furthermore, they may pave the way for the development of targeted therapeutic strategies specifically focused on this process.

Abstract
Background Carotid artery stiffness is associated with cognitive impairment and dementia, but the underlying mechanisms remain unknown. We examined the associations of carotid artery stiffness with cerebral small-vessel disease markers, cognition, and dementia subtypes in a memory clinic cohort. Methods and Results A total of 272 participants underwent carotid ultrasonography, 3 Tesla brain magnetic resonance imaging, and neuropsychological assessment. Carotid ultrasonography was used to assess β-index, pressure-strain elastic modulus, and pulse-wave velocity-β. Brain magnetic resonance images were graded for cerebral small-vessel disease markers, including white matter hyperintensities, lacunes, and cerebral microbleeds. Participants were classified as having no cognitive impairment, cognitive impairment and no dementia, or dementia subtyped as Alzheimer disease and vascular dementia. Cognition was assessed using National Institute of Neurological Disorders and Stroke-Canadian Stroke Network harmonization battery. After adjusting for age, sex, cardiovascular risk factors, and diseases, multivariable models showed that β-index (β=0.69; P=0.002), elastic modulus (β=0.78; P<0.001), and pulse-wave velocity-β (β=0.80; P<0.001) were associated with white matter hyperintensities, and elastic modulus (odds ratio [OR], 1.39 [95% CI, 1.04-1.85]) and pulse-wave velocity-β (OR, 1.47 [95% CI, 1.10-1.98]) were independently associated with lacunes. Similarly, β-index (OR, 2.04 [95% CI, 1.14-4.13]), elastic modulus (OR, 2.22 [95% CI, 1.25-4.42]), and pulse-wave velocity-β (OR, 2.50 [95% CI, 1.36-5.18]) were independently associated with vascular dementia. Carotid stiffness measures were independently associated with worse performance in global cognition, visuomotor speed, visuospatial function, and executive function. These associations became largely nonsignificant after further adjusting for cerebral small-vessel disease markers. Conclusions In memory clinic patients, carotid artery stiffness was associated with white matter hyperintensities and lacunes, impairment in global and domain-specific cognition, and causative subtypes of dementia, particularly vascular. The effects of carotid stiffness on cognition were not independent of, and were partially mediated by, cerebral small-vessel disease.

Abstract
OBJECTIVE To explore the correlation of coagulation function with the severity and prognosis of acute pancreatitis (AP) and identify the laboratory markers for early prediction and dynamic monitoring of the prognosis of AP. METHODS We retrospectively analyzed the clinical data of patients with AP admitted less than 72 h after onset to our hospital from December 1, 2017 to November 30, 2018. The correlation of coagulation function-related markers at admission and their changes during hospitalization with the prognosis of the patients was analyzed. RESULTS We screened the data of a total of 1260 patients with AP against the inclusion and exclusion criteria, and eventually 175 patients were enrolled in this analysis, among whom 52 patients had severe AP (SAP) and 12 patients died. Logistic regression analysis identified vWF: Ag, PT, PC, AT Ⅲ and D-dimer markers at admission as independent risk factors for predicting SAP and death. Dynamic monitoring of the changes in coagulation function-related markers in the disease course had greater predictive value of the patients' prognosis, and the indicators including vWF: Agmax, PTmax, APTTmax, TTmax, FIBmin, D-dimermax, PLTmin, PCmin, PLGmin, AT Ⅲmin, and their variations were all independent risk factors for predicting SAP and death. ROC analysis suggested that dynamic monitoring of the changes in the indicators, especially those of △vWF: Ag, △PT, △APTT, △FIB, △TT, △D-dimer, △PLT, △PC, △AT Ⅲ, △PLG, could effectively predict SAP and death in these patients (with AUC range of 0.63-0.84). CONCLUSION Patients with AP have vascular endothelial injuries and coagulation disorders. The markers including vWF: Ag, PT, PC, AT Ⅲ and D-dimer at admission are independent risk factors for predicting SAP and death, and dynamic monitoring of the changes in vWF: Ag、PT、APTT、TT、FIB、D-dimer、PLT、PC、AT Ⅲ and PLG can further increase the predictive value.

Abstract
BackgroundNipocalimab (JNJ-80202135, M281) is a fully human IgG1 monoclonal antibody (mAb) designed to bind to the human FcRn receptor with high affinity at both neutral and acidic pH, and is currently in investigational clinical trials. The primary role of FcRn is to extend the half-life of IgG due to its ability to bind, salvage, and recycle IgG in the circulation. Nipocalimab specifically targets the FcRn IgG binding site, thereby interfering with the binding of native IgG, reducing IgG recycling and accelerating IgG clearance (1).ObjectivesTo determine the biodistribution of nipocalimab compared to an isotype control IgG in huFcRn transgenic (Tg32) mice. This type of study is well suited to non-invasively determine the blood PK of labeled antibodies, as well as the kinetic biodistribution into various organ systems.MethodsFour formulations were prepared for dosing: nipocalimab-VT680XL (N027a), nipocalimab-VT680XL plus 2x unlabeled nipocalimab (N027b), isotype control IgG-VT680XL and control vehicle. The biodistribution assessment experiments were performed in Tg32 mice (n=3/group, strain: B6.Cg-Fcgrttm1Dcr Tg(FCGRT)32Dcr/DcrJ). A time series of in vivo fluorescence-mediated tomography (FMT) imaging sessions of body and brain was collected to follow the biodistribution of antibodies (Abs) after single IV administration. In vivo, whole body fluorescence was assessed immediately after administration of each formulation, and at 1, 5, 24, 48, 72, 96 and 144 hrs post administration. Mice were sacrificed after the final in vivo imaging timepoint, followed by resection of tissues and ex vivo imaging. The in vivo tissues were also assessed ex vivo at the terminal time point by epifluorescence. Ex vivo epifluorescence measurements were obtained for gall bladder, muscle, spleen, pancreas, white blood cells, lymph nodes, and intestines, which were flushed prior to imaging to remove fecal material.ResultsBiodistribution of nipocalimab and control IgG1 mAb were similarly observed to exhibit 2-compartment blood pharmacokinetics, dominant liver accumulation with minimal kidney and bladder signal and a prolonged terminal half-life in circulation (70-90 h). Nipocalimab showed only subtle differences compared to IgG1 control antibody, attributed to specific binding to target antigen. Early tissue accumulation/binding was seen between 1 and 5 hrs post-injection, which yielded an apparent, modest increase in blood clearance and a slightly lower AUC as compared to control IgG. The bulk of increased tissue binding could be attributed to liver retention, with trends for lower accumulation/binding in other tissues, such as pancreas, lung, and muscle. Addition of 2-fold excess of unlabeled nipocalimab to the labeled nipocalimab yielded some small trends of changes in biodistribution of the labeled material.ConclusionWhole body biodistribution and blood pharmacokinetics of nipocalimab were similar to that observed for the isotype control IgG1 antibody. Nipocalimab exhibited a subtle trend towards higher liver distribution within the first 5 hours after dosing and a more rapid distribution phase compared to the control antibody. This is possibly related to its FcRn targeting and its shorter anticipated half-life compared to isotype control IgG or other human IgG mAbs. Overall results for both nipocalimab and control IgG were typical for IgG mAbs.References[1]Ling L. et al.

Abstract
Objective: To explore the correlation between blood glucose levels and the three factors of sarcopenia (muscle mass, strength and function) in older Chinese community dwellers. Methods: This is a retrospective study conducted by collecting the data of patients in Jiangsu Huaqiao Road Community Health Service Center from 2018 to 2019. Two hundred and fifty people aged 60 years or elder were selected. Among them, 101 were men and 149 were women. According to the American Diabetes Association diagnostic criteria for diabetes mellitus in 2018, they were divided into normal glucose tolerance (NGT) group, pre-diabetes group and diabetes group. The patients were assessed for sarcopenia as well. Results: Compared with those in the NGT group, muscle mass and upper limb muscle strength did not change in the diabetic group, but lower limb muscle strength and body function [walking speed, balance, short physical performance battery (SPPB)] decreased significantly in the diabetic group. Pearson correlation analyses showed that fasting plasma glucose(FPG) was negatively correlated with walking speed (r=-0.248, P=0.001), three-pose balance (r=-0.166, P=0.013) and SSPB (r=-0.213, P=0.001). Glycosylated hemoglobin A1c(HbA1c) was positively correlated with sitting and standing time (r=0.205, P=0.002), and negatively correlated with three-pose balance (r=-0.186, P=0.006) and SSPB (r=-0.154, P=0.024). Multiple regression analyses showed that FPG was negatively associated with walking speed (β=-0.125, P=0.005) and SPPB (β=-0.034, P=0.012), and that HbA1c was positively associated with sitting and standing time (β= 0.218, P =0.006) and negatively associated with three-pose balance (β=-0.143, P=0.012), and SPPB (β=-0.117, P =0.036). Conclusions: There is no significant correlation between blood glucose levels and muscle mass in the elderly; however, FPG is closely correlated with gait speed, and HbA1c is closely correlated with muscle strength of lower limbs and balance ability in the elderly.

Abstract
This study aims to investigate the effect of resveratrol on intrahepatic cholestasis of pregnancy (ICP) and its effect on the gut microbiome profiles, thus contributing to the potential therapeutic strategies for ICP. ICP rat models were established by injecting 17α-ethinylestradiol (EE) subcutaneously from the thirteenth day of gestation for four days and then treated with EE (D group, n=5), resveratrol (R group, n=5), or ursodeoxycholic acid (UDCA; U group, n=5) from the seventeenth to the twentieth day of gestation. Fecal samples were analyzed with 16S ribosomal RNA (rRNA) sequencing. In results: the gut microbiota of pregnant rats was characterized with reduced alpha diversity (Chao1 index), and significant variation in the microbiota structure (ANOSIM) was also observed after being treated with EE. The richness of four phyla and ten genera was upregulated, and five phyla and ten genera were downregulated by EE treatment. The dysbiosis of Bilophila, Ruminococcus, and Actinobacteria caused by EE treatment was reversed by resveratrol administration. There was a correlation between total bile acid and alanine aminotransferase in ICP rats. The Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis results suggested that the secondary bile acid biosynthesis was decreased, and the alanine, aspartate, and glutamate metabolism was increased after being treated with EE in pregnant rats. In conclusion, EE treatment could lead to gut microbiome dysbiosis and bile acid metabolism dysregulation in pregnant rats. Resveratrol could partially rescue gut microbiota dysbiosis and improve the biochemical characteristics caused by EE treatment.

Abstract
Multiple myeloma is the second most common hematologic malignancy worldwide. Despite the growing number of available therapeutic options and advances in the treatment since the 2000s, relapse of multiple myeloma is inevitable. Currently, the main therapeutic agents for multiple myeloma treatment include proteasome inhibitors, immunomodulatory drugs, monoclonal antibodies and others. Patients who relapse or are refractory to the above-mentioned treatments have poor prognosis. B-cell maturation antigen (BCMA) is a cell-surface receptor which is expressed on the membrane of multiple myeloma cells, but absent on naive and memory B cells, making it an ideal target for multiple myeloma treatment. Belantamab mafodotin (GSK-2857916) is a first-in-class BCMA antibody-drug conjugate with an overall response rate of 32% in the phase II clinical trial DREAMM-2, which is a phase II study designed to investigate the efficacy and safety of belantamab mafodotin in relapsed/refractory patients with multiple myeloma. In August 2020, based on the results of this pivotal DREAMM-2 study, the U.S. Food and Drug Administration (FDA) approved belantamab mafodotin as a monotherapy for relapsed/refractory multiple myeloma. Thereafter, the European Medicines Agency (EMA) also approved this indication. Although belantamab mafodotin has demonstrated single-agent activity in relapsed/refractory multiple myeloma, further studies to evaluate its efficacy and its combinational use with other drugs are necessary and ongoing.

Abstract
Objective: To explore the spatiotemporal distribution and macro-related factors of congenital syphilis in Guangdong province and provide suggestions and recommendations for prevention. Methods: Yearly reported cases of syphilis and some influencing factor data of Guangdong province were collected from 2005 to 2017. The spatiotemporal distribution of congenital syphilis was described. Meanwhile, the spatial panel data model was constructed to analyze the relationship between the incidence rates of congenital syphilis and related factors. Results: From 2005 to 2017, 13 361 cases of congenital syphilis were reported in Guangdong province. The number of congenital syphilis cases rose to its highest point during 2005-2011. A slow downward trend followed. The peaks of incidence were observed from August to December. The incidence of the non-Pearl River Delta region has experienced a process of rising first and then decreasing. The spatial panel data model results showed that congenital syphilis had significant positive spatial autocorrelation (P<0.001). The incidence of primary and secondary syphilis in women (β=0.822,P<0.001), gross domestic product per capita (β=3.511,P<0.001), net migrate rate (β=0.215,P=0.047) and maternal system management rate(β=0.017,P=0.021) were all positively correlated with the incidence rates of congenital syphilis. Registered population density (β=-1.167,P<0.001) and prenatal examination rate (β=-0.038,P=0.031) was negatively correlated with congenital syphilis. Conclusions: The incidence of congenital syphilis was spatially aggregated in Guangdong province from 2005 to 2017. The intensity of prevention might be strengthened in cities with developed economies and high net migration rates, which have high risks of congenital syphilis. Controlling the incidence of primary and secondary syphilis in women and increasing the prenatal examination rate for pregnant women appears effective prevention measures of congenital syphilis.

Abstract
OBJECTIVE To investigate the expression of long noncoding RNA (LncRNA) MIRG and its potential functions in regulating osteoclastogenesis and bone resorption function through modulating miR-1897 in bone marrow macrophages (BMMs). MATERIALS AND METHODS qRT-PCR was performed to detect the expressions of MIRG and its co-expression mRNA NFATc1 at different stages during osteoclastogenesis. The CCK-8 assay was performed to evaluate cell proliferation and differentiation. The correlation between miR-1897 and MIRG was detected by statistical analysis. Bioinformatics and luciferase assay were performed to explore the interaction and binding site of MIRG and miR-1897. We also cloned the mice NFATc1 3'-UTR into the luciferase reporter vector and constructed miR-1897 binding mutants to validate the inhibited regulation of miR-1897 to the expression of NFATc1. RESULTS Results showed that expressions of MIRG and NFATc1 were upregulated during osteoclastogenesis. qRT-PCR and CCK-8 assay showed that MIRG expression is associated with osteoclastogenesis and bone resorption. The bioinformatics prediction and luciferase assay suggested that by interacting with miR-1897, MIRG acts as a molecular sponge for the miR-1897 target NFATc1, to partly modulate the inhibitory effect of miR-1897 on NFATc1. CONCLUSIONS We found that lncRNA-MIRG was upregulated in osteoclasts, which could promote osteoclastogenesis and bone resorption function as a molecular sponge by modulating the inhibitory effect of miR-1897 on NFATc1.

Abstract
Abstract
Background
The impact of catheter ablation (CA) for atrial fibrillation (AF) in patients with heart failure with preserved ejection fraction (HFpEF) is unknown.
Objectives
To determine whether CA for AF reverses adverse haemodynamic changes associated with HFpEF.
Methods
Consecutive consenting patients with EF ≥50% scheduled for index CA underwent baseline exercise right heart catheterisation (exRHC), cardiac output (CO) measurement, cardiac MRI, echocardiogram, QOL questionnaires and BNP testing. HFpEF was defined by resting pulmonary capillary wedge pressure (PCWP) ≥15mmHg or peak exercise PCWP ≥25 mmHg during exRHC. Patients with HFpEF were offered follow-up exRHC ≥6 months post-CA.
Results
Of 252 patients scheduled for CA between April 2017 and Sept 2019, 131 (51.9%) qualified for inclusion, 65 (49.6%) consented to exRHC and 11 (16.9%) were excluded due to a subsequent decrease in EF (10) and uncontrolled hypertension (1). Fifty-four underwent exRHC, with 35 (65%) meeting criteria for HFpEF. Of them 26 (74.3%) who underwent CA, 20 (77%) had a follow up exRHC at 12±6 months follow-up, showing an overall decrease in peak exercise PCWP from 30.3±4.2 to 26.8±4.7 mmHg (p<0.05). Patients without arrhythmia recurrence showed significant improvements in peak exercise PCWP (29.2±3.7 to 22.9±2.0 mmHg (p<0.01). Their cardiac output increased from 10.3±3.0 to 12.1±4.0 mmHg p=0.1), and BNP decreased from (94.6±101.6 to 38.0±34.0 mmHg (p=0.06),whereas those with arrhythmia recurrence did not. Overall, 9 patients (45.0%) no longer met criteria for HFpEF.
Conclusion
There is a high prevalence of HFpEF in people referred for AF ablation. Successful CA for AF reverses the adverse haemodynamic changes associated with HFpEF
Changes in PCWP following AF ablation

Abstract
Abstract
Background
Sleep disturbances and substance abuse are prevalent in adolescents, often associated with adverse behavioral outcomes and daytime dysfunction. While sleep problems are often seen as consequences to alcohol use, they are risk factors for alcohol misuse and related consequences. However, current evidence in adolescents and young adults (AYA) is mostly observational and is not well-documented in recent years. This systematic review aims to assess the literature surrounding sleep difficulties and their effects on subsequent alcohol misuse in AYA.
Methods
Medline, PsycINFO, and EMBASE were searched for observational studies assessing alcohol consumption, alcohol-related consequences, and self-reported sleep difficulties in AYA aged 16-25. Studies with clinical samples and randomized trials were excluded. Data on measurement tools, measures of association, and sample characteristics were recorded using a standardized form. Associations between sleep difficulties and alcohol misuse were qualitatively summarized by study type (cross-sectional and longitudinal studies). Risk of bias was assessed using CLARITY tools.
Results
Of 7706 records retrieved from databases, 24 studies met the inclusion criteria. Cross-sectional studies (n = 17) found insomnia-like symptoms (difficulties falling/staying asleep, frequent night-time awakenings) were significantly associated with alcohol use frequency and intensity (n = 16) and subsequent intoxication (n = 6). Among longitudinal studies (n = 7), persistent erratic sleep behaviors at baseline were associated with frequent binge-drinking (n = 2) and increased odds of interpersonal problems (n = 2) and risky behaviors at follow-up (n = 1).
Conclusions
The present review assesses the role of sleep difficulties in alcohol use behaviors and related consequences in AYA. Sleep inadequacies are involved in alcohol misuse, prompting investigations to clarify sleep's etiological role in alcohol use behaviors to prevent negative consequences in AYA.
Key messages
Sleep disturbances need to be investigated further as possible risk factors for incident alcohol misuse in young adults. Addressing sleep hygiene and promoting healthy sleep behaviors are important in evaluating the overarching public health issue of alcohol addiction and misuse in adolescents.

Abstract
Abstract
Background
Cancer is a major public health concern as it is a leading cause of death worldwide. The risk of endocrine-related cancers may be associated with suboptimal sleep quality due to disruptions in circadian rhythm. However, the extent of this relationship is not clear and warrants a review summarizing recent research findings. This systematic review aims to provide an updated summary of the literature surrounding the association between night shift work, sleep quality, circadian rhythm disruption and the risk of endocrine-related cancers.
Methods
MEDLINE, EMBASE, CINAHL, and Web of Science databases have been searched for related cohort, case-control, and cross-sectional studies. The search was limited to studies published in English, after the year 2000. Non peer-reviewed literature and randomized control trials, were excluded. Reviewers will independently extract data on study characteristics, sleep quality measures, circadian rhythm measures, cancer diagnosis, and outcome measures. Risk of bias assessment will be performed using the CLARITY tools.
Results
Data synthesis is ongoing. Associations between sleep quality, night shift work, circadian disruption and risk of endocrine-related cancer will be summarized and risk estimates will be reported for four endocrine-related cancers: breast, prostate, thyroid, ovarian, and endometrial cancer. If data are available, subgroup analyses will be carried out by cancer type, study design, and age group.
Conclusions
This review qualitatively synthesizes current literature to determine the extent of the association between sleep quality, night shift work, circadian rhythm disruption and the risk of endocrine-related cancers. These findings can contribute to population-level cancer prevention efforts and aid public health promotion of healthier sleep-related behaviours.
Key messages
The relationship between sleep quality and endocrine-related cancers should be explored further in public health research due to inconclusive evidence from current literature. The findings of this project can help promote healthy sleep behaviours and population-level cancer prevention.

Abstract
Mucosal-associated invariant T (MAIT) cells in HIV-1-infected individuals are functionally impaired by poorly understood mechanisms. Single-cell transcriptional and surface protein analyses revealed that peripheral MAIT cells from HIV-1-infected subjects were highly activated with the up-regulation of interferon (IFN)-stimulated genes as compared to healthy individuals. Sustained IFN-α treatment suppressed MAIT cell responses to Escherichia coli by triggering high-level interleukin-10 (IL-10) production by monocytes, which subsequently inhibited the secretion of IL-12, a crucial costimulatory cytokine for MAIT cell activation. Blocking IFN-α or IL-10 receptors prevented MAIT cell dysfunction induced by HIV-1 exposure in vitro. Moreover, blocking the IL-10 receptor significantly improved anti-Mycobacterium tuberculosis responses of MAIT cells from HIV-1-infected patients. Our findings demonstrate the central role of the IFN-I/IL-10 axis in MAIT cell dysfunction during HIV-1 infection, which has implications for the development of anti-IFN-I/IL-10 strategies against bacterial coinfections in HIV-1-infected patients.

Abstract
Colorectal cancer is one of the most common malignant tumors with a high rate of distant metastasis, postoperative recurrence and mortality. ATPase family AAA domain-containing protein 2 (ATAD2), a member of ATPase family, is highly expressed in various cancers, including colorectal cancer. However, whether ATAD2 plays a role in the migration and invasion of colorectal cancer cells remains unknown. In this study, we established ATAD2 knockdown in colorectal cancer cell lines by RNA interference and found that silencing of ATAD2 inhibited the migration and invasion ability of Caco-2 and SW-480 cells. Moreover, ATAD2 silencing suppressed epithelial-mesenchymal transition (EMT), and reduced the expression and enzymatic activity of matrix metalloproteinases (MMPs) in Caco-2 and SW-480 cells. In summary, our results suggest that silencing of ATAD2 inhibits migration and invasion of colorectal cancer cells by suppressing EMT and decreasing the activity of MMPs. Hence, ATAD2 could be considered as a novel molecular marker of metastatic colorectal cancer, and it may provide new insights for clinical diagnosis and treatment of colorectal cancer.

Abstract
Whereas high-flow nasal cannula use is gaining prevalence, its high gas flow raises concerns about aerosolization of infectious particles and spread of infection. This randomized controlled crossover non-inferiority trial (N = 20) evaluated the degree of environmental contamination by viable bacteria associated with the use of high-flow nasal cannula compared with conventional oxygen mask for critically ill patients with Gram-negative pneumonia. The results show that high-flow nasal cannula use was not associated with increased air or contact surface contamination by either Gram-negative bacteria or total bacteria, suggesting that additional infection control measures are not required.

Abstract
Ten patients diagnosed with multifocal motor neuropathy (MMN) were recruited in the Department of Neurology at Chinese PLA General Hospital from January 1, 2009 to August 31, 2015. The clinical and electrophysiological features were analyzed retrospectively. All patients complained of progressive asymmetric limb weakness, which was more severe in distal than in proximal. Five presented muscle atrophy. None had sensory disturbances. All suffered diminished or disappeared tendon reflex, whereas Babinski signs were negative. Multi-focal conduction block (CB) was confirmed by nerve conduction studies (NCS) in all patients and 7 showed spontaneous potentials in needle electrode electromyography. Abnormal sensory nerve conduction was seen in 3 patients. Laboratory test revealed anti-ganglioside GM1 antibody in cerebrospinal fluid (CSF) in 6 cases and elevated CSF protein in 7 cases. Limb weakness alleviated greatly in 9 cases after intravenous immunoglobulin (IVIg) treatment. But the other one reported poor response, who had long course of disease, serious limb weakness and obvious muscle atrophy. Motor nerve damage is the most important manifestation of MMN and sensory nerve damage may also appear. NCS is essential to the diagnosis of this disease, with CB as the characteristic electrophysiological feature. IVIg is an effective treatment.

Abstract
Objective: To investigate the feature of repetitive nerve stimulation (RNS) in patients with amyotrophic lateral sclerosis (ALS) and correlation between RNS and clinical features and electromyography (EMG) findings of the corresponding muscle. Methods: Needle EMG and RNS were performed in 53 patients with ALS, who were recruited into Department of Neurology of Chinese PLA general hospital during April to December in 2016. Decrement of the compond muscle action potential (CMAP) in response to RNS of different nerves and stimulus frequencies was compared. The effects of gender, age of onset, disease duration, region of onset, ALS functional rating scale-revised (ALSFRS-R) and rate of disease progression (ΔFS) on the decrement were analyzed. Results: 49.1% of patients with ALS had decremental responses to low frequency RNS (LF-RNS) in accessory nerve, which was lower in ulnar nerve (4.3%) and common peroneal nerve (2.6%). Decremental responses of accessory nerve at 3 Hz were observed in 49.1% of patients with ALS, more frequent than 30.2% at 1 Hz. None of the patients had increased responses to high frequency RNS. Patients with upper-limb-onset, longer disease duration and lower ALSFRS-R tended to have more frequent decrement of CMAP in response to RNS. The decrement with LF-RNS of accessory nerve was in concert with neurogenic damage of sternocleidomastoid muscle with needle EMG (r=0.365, P=0.007). There were 3 patients who had decremental responses to LF-RNS in accessory nerve without clinical involvement and neurogenic damage of sternocleidomastoid muscle. Conclusions: There is significant decrement of CMAP in response to LF-RNS of accessory nerve in patients with ALS, which may reveal neuromuscular junction (NMJ) impairment. It may indicated a dying-back pattern of disease progression which derived from motor neuron terminal or NMJ to neuronal soma that some patients with ALS have decremental responses in RNS without clinical involvement and neurogenic damage of sternocleidomastoid muscle.
