Abstract
The aim of this paper was to investigate the clinical and magnetic resonance imaging (MRI) features of synovial chondromatosis (SC) of the temporomandibular joint (TMJ). Fourteen patients with SC of the TMJ were included in the study. Clinical and MRI features were analysed and divided into three types based on MRI classification: type I with loose bodies, type II with homogeneous masses, and type III with a mixture of loose bodies and homogeneous masses. All SCs occurred in the superior compartment of the TMJ. There were two patients (14%) categorised as type I, five (36%) as type II and seven (50%) as type III. Four patients (29%) had disc perforation, and nine had bone erosion; among those nine, seven (78%) had type III and two (22%) type II. Histological examination showed inflammation and calcification in the synovial membrane and, and cartilage of the hyaline type in all cases. MRI has advantages in the diagnosis of SC.

Abstract
Objective: To retrospectively analyze the relationship between serum C-reactive protein (CRP), serum cholinesterase (ChE), prealbumin (PA) and mortality in severe patients with coronavirus disease 2019 (COVID-19). Methods: During the period from January 29 to March 30, 2020, a total of 344 COVID-19 patients were admitted to west branch of Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. One-hundred and ninety-two patients were diagnosed with common type and excluded, and 34 patients were transferred to LeiShenShan or other medical units. The remaining 118 patients were severe cases, and 18 cases were excluded due to incomplete data. A total of 100 severe COVID-19 patients were finally collected. According to the outcome, the patients were divided into death group (37 cases) and survival group(63 cases), and the levels of serum CRP, ChE and PA were compared. Statistical analysis were performed by SPSS25.0. Results: There were 53 male patients in this study. The level of CRP in death group was significantly more elevated compare to the survival group [(95.72±39.56) mg/L vs. (22.21±20.75) mg/L, P<0.01]. On the contrary, serum ChE in death group was remarkably decreased [(5 082±1 566) U/L vs. (7 075±1 680) U/L, P<0.01]. Also, serum PA in death group was significantly lower [(86.18±47.94) mg/L vs. (167.40±57.82) mg/L, P<0.01]. Univariate analysis showed that CRP and PA had an impact on the survival of critical patients, but multivariate Cox regression analysis suggested that CRP was the independent factor affecting the survival of critical patients. Conclusions: CRP is generally elevated in severe patients with COVID-19, and serum ChE and PA accordingly decrease. CRP and PA have influence on patients' survival, but only CRP demonstrates predictive value for prognosis in critical patients with COVID-19.

Abstract
Living in rapidly changing environments has shaped the mammalian brain toward high sensitivity to abrupt and intense sensory events-often signaling threats or affordances requiring swift reactions. Unsurprisingly, such events elicit a widespread electrocortical response (the vertex potential, VP), likely related to the preparation of appropriate behavioral reactions. Although the VP magnitude is largely determined by stimulus intensity, the relative contribution of the differential and absolute components of intensity remains unknown. Here, we dissociated the effects of these two components. We systematically varied the size of abrupt intensity increases embedded within continuous stimulation at different absolute intensities, while recording brain activity in humans (with scalp electroencephalography) and rats (with epidural electrocorticography). We obtained three main results. 1) VP magnitude largely depends on differential, and not absolute, stimulus intensity. This result held true, 2) for both auditory and somatosensory stimuli, indicating that sensitivity to differential intensity is supramodal, and 3) in both humans and rats, suggesting that sensitivity to abrupt intensity differentials is phylogenetically well-conserved. Altogether, the current results show that these large electrocortical responses are most sensitive to the detection of sensory changes that more likely signal the sudden appearance of novel objects or events in the environment.

Abstract
PURPOSE Both high-density lipoprotein cholesterol (HDL-C) and body mass index (BMI) have an impact on the prevalence of stroke. However, it is unclear whether BMI can modify the relationship between HDL-C and stroke. Therefore, we aimed to assess the effect of the BMI on the association between HDL-C and stroke in a hypertensive population without atrial fibrillation (AF). METHODS We analyzed data of 10,925 hypertensive patients without AF from the Chinese Hypertension Registry Study. BMI was categorized as < 24 and ≥ 24 kg/m2. Multivariate logistic regression and smooth curve fitting (penalized spline method) were used to analyze the association between HDL-C and stroke in different BMI groups. Subgroup analysis and interaction tests were used to explore the effect of other variables on this relationship. RESULTS The results showed a negative association between HDL-C and stroke in the BMI < 24 kg/m2 group, but HDL-C was not associated with stroke in the BMI ≥ 24 kg/m2 group. In the BMI < 24 kg/m2 group, each 1 mmol/L increase in HDL-C was associated with a 50% decreased risk of stroke [odds ratio (OR) 0.50, 95% confidence interval (CI) 0.38-0.66]. No significant relationship between HDL-C and stroke was observed in the BMI ≥ 24 kg/m2 group (OR 0.73, 95% CI 0.49-1.10). There was a significant interaction between BMI and HDL-C in regard to the prevalence of stroke in the hypertensive population without AF (PInteraction = 0.027). CONCLUSIONS We found an inverse association between HDL-C and stroke only in the BMI < 24 kg/m2 group. The finding suggested that BMI could modify the association between HDL-C and stroke in hypertensive populations without AF.

Abstract
Objective: To explore the relationship between NOX4 and radiosensitivity of nasopharyngeal carcinoma cells. Methods: Western blot was used to test the expression of NOX4 in nasopharyngeal carcinoma cells (CNE1, CNE2 and HONE1) and normal nasopharyngeal epithelial cells (NP69). The lentiviral vectors for RNA interference and overexpression of NOX4 gene were constructed and nasopharyngeal carcinoma cells were transfected. After treatment with radiation or/and PI3K/AKT inhibitor LY294002, the expressions of related proteins in cells were tested by Western blot, and the cell proliferation was detected by CCK-8 assay and the cell apoptosis was determined by flow cytometry. GraphPad Prism 5 was used for statistical analysis, and P<0.05 was statistically significant. Results: The expressions of NOX4 in nasopharyngeal carcinoma cells were higher than those in normal nasopharyngeal epithelial cells. Compared with the siNC group, the siNOX4 group of nasopharyngeal carcinoma cell had lower proliferation capacity [72 h absorbance (A) value:1.16 vs. 0.75] and higher apoptosis rate (2.9% vs. 10.0%). In contrast,compared with the vector group, the NOX4 group of nasopharyngeal carcinoma cell had higher proliferation capacity [72 h absorbance (A) value: 1.01 vs. 1.32] and lower apoptotic rate (1.7% vs. 1.1%).Treatment with LY294002 for nasopharyngeal carcinoma cells of NOX4 overexpression,compared with the NOX4 group, the proliferation ability of nasopharyngeal carcinoma cells in the NOX4+LY294002 group was reduced (72 h absorbance (A) value: 1.32 vs. 0.77), while the apoptotic rate was increased (1.1% vs. 3.1%).Treatment with radiotherapy, compared with the siNC/Vector group, the proliferation ability of nasopharyngeal carcinoma cells in the siNOX4 group was reduced (72 h absorbance (A) value: 0.72 vs. 0.33), and the apoptotic rate was increased (7.8% vs. 17.3%). However, in the NOX4 group, the proliferation of nasopharyngeal carcinoma cells was enhanced (72 h absorbance (A) value:0.65 vs. 0.78), and the apoptotic rate was reduced (8.1% vs. 3.8%). Compared with the NOX4+radiation group, the proliferation ability of nasopharyngeal carcinoma cells in the NOX4+radiation+LY294002 group was reduced (72 h absorbance (A) value: 0.79 vs. 0.56), while the apoptotic rate was increased (3.8% vs. 8.1%). Conclusion: NOX4 can inhibit radiosensitivity of nasopharyngeal carcinoma cells possibly by activating PI3K/AKT pathway.

Abstract
INTRODUCTION Kinesiophobia, the fear of physical movement and activity related to injury vulnerability, has been linked to sub-optimal outcomes following total knee replacement (TKR). This systematic review has two aims: to define the relationship between kinesiophobia and functional outcomes, pain and range of motion following TKR, and to evaluate published treatments for kinesiophobia following TKR. MATERIALS AND METHODS A primary search of electronic databases, grey literature, and trial registries was performed in March 2020. English-language studies recruiting adult primary TKR patients, using the Tampa Scale of Kinesiophobia (TSK) were included. Outcome measures were grouped into short (< 6 months), medium (6-12 months), and long term (> 12 months). Study quality was assessed using the Newcastle Ottawa Scale for cohort or case control studies, and the Cochrane Collaboration Risk of Bias tool for randomised controlled trials. RESULTS All thirteen included papers (82 identified) showed adequately low risk of methodological bias. TSK1 (activity avoidance) correlated with WOMAC functional score at 12 months in three studies (r = 0.20 p < 0.05, R = 0.317 p = 0.001, and correlation coefficient 0.197 p = 0.005). TSK score significantly correlated with mean active range of motion (ROM) at 2 weeks [65.98 (SD = 14.51) versus 47.35 (SD = 14.48) p = 0.000], 4 weeks [88.20 (SD = 15.11) versus 57.65 (SD = 14.80) p = 0.000], and 6 months [105.33 (SD = 12.34) versus 85.53 (SD = 14.77) p = 0.000] post-operation. Three post-operative interventions improved TSK score vs control following TKR: a home-based functional exercise programme [TSK - 14.30 (SD = 0.80) versus - 2.10 (SD = 0.80) p < 0.001], an outpatient cognitive behavioural therapy (CBT) programme [TSK 27.76 (SD = 4.56) versus 36.54 (SD = 3.58)], and video-based psychological treatment [TSK 24 (SD = 5) versus 29 (SD = 5) p < 0.01]. CONCLUSIONS Kinesiophobia negatively affects functional outcomes up until 1 year post-operatively, while active ROM is reduced up to 6 months post-procedure. Post-operative functional and psychological interventions can improve kinesiophobia following TKR.

Abstract
Nucleotide-binding oligomerization domain (NOD)-like receptor 1 (NOD1) is a cytosolic pattern recognition receptor with a crucial role in the innate immune response of cells triggered by the presence of compounds such as gamma-d-glutamyl-meso-diaminopimelic acid (iE-DAP) present in the peptidoglycan of all gram-negative and certain gram-positive bacteria. Methionine (Met) and arginine (Arg) are functional AA with immunomodulatory properties. In the present study, we aimed to assess the effect of increased Met and Arg supply on mRNA abundance of genes associated with innate immune response, antioxidant function, and AA metabolism during iE-DAP challenge in bovine mammary epithelial cells (BMEC). Primary BMEC (n = 4 per treatment) were precultured in modified medium for 12 h with the following AA formulations: ideal profile of AA (control), increased Met supply (incMet), increased Arg supply (incArg), or increased supply of Met plus Arg (incMetArg). Subsequently, cells were challenged with or without iE-DAP (10 μg/mL) for 6 h. Data were analyzed as a 2 × 2 × 2 factorial using the MIXED procedure of SAS 9.4. Greater mRNA abundance of NOD1, the antioxidant enzyme SOD1, and AA transporters (SLC7A1 and SLC3A2) was observed in the incMet cells after iE-DAP stimulation. Although increased Met alone had no effect, incMetArg led to greater abundance of the inflammatory cytokine IL-6, and the antioxidant enzyme GPX1 after iE-DAP stimulation. The increased Arg alone downregulated NOD1 after iE-DAP stimulation, coupled with a downregulation in the AA transporters mRNA abundance (SLC7A1, SLC7A5, SLC3A2, and SLC38A9), and upregulation in GSS and KEAP1 mRNA abundance. Overall, the data indicated that increased supply of both Met and Arg in the culture medium were more effective in modulating the innate immune response and antioxidant capacity of BMEC during in vitro iE-DAP stimulation.

Abstract
Quantum correlations in observables of multiple systems not only are of fundamental interest, but also play a key role in quantum information processing. As a signature of these correlations, the violation of Bell inequalities has not been demonstrated with multipartite hybrid entanglement involving both continuous and discrete variables. Here we create a five-partite entangled state with three superconducting transmon qubits and two photonic qubits, each encoded in the mesoscopic field of a microwave cavity. We reveal the quantum correlations among these distinct elements by joint Wigner tomography of the two cavity fields conditional on the detection of the qubits and by test of a five-partite Bell inequality. The measured Bell signal is 8.381±0.038, surpassing the bound of 8 for a four-partite entanglement imposed by quantum correlations by 10 standard deviations, demonstrating the genuine five-partite entanglement in a hybrid quantum system.

Abstract
OBJECTIVE To observe whether edaravone has a therapeutic and protective effect on retinal injury in diabetic rats through the nuclear factor-κB (NF-κB) pathway. MATERIALS AND METHODS The Sprague-Dawley rat model of diabetes was established and divided into diabetes model group (model group) and edaravone treatment group (treatment group). Also, normal control group (control group) was set up. After successful modeling, the blood and retinal tissues of rats were collected. Then, the blood glucose content and serum interleukin-6 (IL-6) were detected. Antioxidant indexes, superoxide dismutase (SOD), and malondialdehyde (MDA), were detected via enzyme-linked immunosorbent assay (ELISA), while the number of corneal nerve fibers was observed microscopically. Moreover, the gene and protein expressions of SOD and NF-κB pathway in tissues were detected via quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) and Western blotting. RESULTS The level of blood glucose in model group was increased compared with that in control group (p<0.05), indicating the successful modeling. The levels of tumor necrosis factor-α (TNF-α), IL-6, and IL-1 were significantly higher in model group than those in control group. In terms of the antioxidant indexes, the level of MDA in model group was significantly higher than that in other two groups, while the level of SOD in treatment group was significantly increased and close to that in control group. Besides, the number of corneal nerve fibers significantly declined in model group, while it was increased in treatment group but still lower than that in control group. According to the gene detection results, the mRNA expression of NF-κB p65 was markedly higher in model group than that in control group, and it was decreased in treatment group, while the mRNA expression of SOD showed the opposite trend. The protein expression of NF-κB p65 was remarkably higher in model group than in control group, was decreased in treatment group, and was close to that in control group, while the protein expression of SOD showed the opposite trend. CONCLUSIONS Edaravone can affect the oxidation and antioxidation through the NF-κB signaling pathway, thereby exerting a therapeutic and protective effect on retinal injury in diabetic rats.

Abstract
The application and understanding of dendritic cell (DC) based immune cancer therapy are largely hindered by insufficient or improper presentation of antigens and the inability to track the homing of reprogrammed DCs to draining lymph nodes in real-time. To tackle these challenges, multi-functional and hierarchically structured silica nanospheres are rationally designed and fabricated, which encapsulate quantum dots to permit near infrared deep tissue imaging and are loaded with carcinoembryonic antigen messenger RNA (CEAmRNA) to enable stable and abundant antigen expression in DCs. After being injected into animals and inducing an antigen-specific immune response, the homing process of reprogrammed labelled DCs from peripheral tissues to draining lymph nodes can be simultaneously and precisely tracked. Significant inhibition of tumor growth is achieved via strong antigen-specific immune responses including induced DC maturation, enhanced T cell proliferation and cytotoxic T lymphocyte (CTL)-mediated responses. Both in vitro and in vivo experiments demonstrate the high effectiveness of this new strategy of imaging-guided cancer immunotherapy by using reprogrammed DCs as immunotherapeutic and tracking agents.

Abstract
Background:Obesity population are rising rapidly and have become a major health issue. Studies have shown that obesity is a low-grade inflammatory status characterized by increase in proinflammatory cytokines.Objectives:To examine the impact of overweight or obesity on disease activity and treatment responses to biologics in patients with ankylosing spondylitis (AS) in a real-world setting.Methods:Body mass index (BMI) is available in 1013 patients from the Chinese Ankylosing Spondylitis Imaging Cohort (CASPIC). Differences in clinical outcomes (such as BASDAI, ASDAS, BASFI, and ASAS HI) and treatment responses to biologics (ΔBASDAI and ΔASDAS) over 3, 6, 9, and 12 months are assessed between BMI categories (normal weight BMI <24 kg/m2; overweight BMI=24-28 kg/m2; obesity BMI ≥28 kg/m2) using Kruskal-Wallis test. The association between BMI and clinical characteristics and treatment responses to biologics was determined, and multivariate median regression analyses were conducted to adjust for confounders (such as age, gender, smoke, and HLA-B27).Results:Among 1013 patients with AS, overweight accounts for 33%, while obesity for 12.4%. There were significant differences between patients who were obese or overweight and those with a normal weight regarding clinical outcomes (BASDAI: 2.90/2.56 vs 2.21; ASDAS-CRP: 2.20/1.99 vs 1.81; BASFI: 2.13/1.69 vs 1.38; ASAS HI: 6.87/5.29 vs 5.12 and BASMI: 2.35/1.76 vs 1.62; all P<0.05). After adjusting for age, gender, smoke, and HLA-B27, obesity remained associated with higher disease activity (BASDAI: β=0.55, P=0.005; ASDAS-CRP: β=0.40, P<0.001), poorer functional capacity (BASFI: β=0.58, P=0.001), worse health index (ASAS HI: β=1.92, P<0.001) and metrology index (BASMI: β=0.71, P=0.013). For TNFi users, BMI was found to be negatively correlated with changes in disease activity (ΔBASDAI and ΔASDAS) in the multivariate regression model (all P<0.05), and overweight and obese patients showed an unsatisfactory reduction in disease activity during 3-month, 6-month, 9-month, and 12-month follow-up period, compared to normal weight patients (all P<0.05).Conclusion:Overweight or obesity impacts greatly on clinical outcomes and treatment responses to biologics in patients with ankylosing spondylitis, which argues strongly for obesity management to become central to prevention and treatment strategies in patients with AS.References:[1]Maachi M, Pieroni L, Bruckert E, et al.

Abstract
OBJECTIVE Coronavirus disease 2019 (COVID-19) has officially been declared a pandemic by the World Health Organization (WHO). Radiological examinations, especially computed tomography (CT), play an important role in the fight against COVID-19. A comprehensive and timely review of radiological role in the fight against COVID-19 remains urgent and mandatory. Hence, the aim of this review is to summarize the radiological role in the fight against COVID-19. This review of current studies on COVID-19 provides insight into the radiological role in the detection, diagnosis, and monitoring for COVID-19. The typical radiological features of COVID-19 include bilateral, multifocal, and multilobar ground glass opacification with patchy consolidation, a peripheral/subpleural or posterior distribution (or both), mainly in the lower lobes. A combination of chest CT and repeat Reverse Transcription-Polymerase Chain Reaction (RT-PCR) testing may be beneficial for the diagnosis of COVID-19 in the setting of strongly clinical suspicion. Chest CT may improve the sensitivity for COVID-19 diagnosis, but patients' exposure to radiation should be kept as low as possible especially for children and pregnant women patients.

Abstract
To realize fault-tolerant quantum computing, it is necessary to store quantum information in logical qubits with error correction functions, realized by distributing a logical state among multiple physical qubits or by encoding it in the Hilbert space of a high-dimensional system. Quantum gate operations between these error-correctable logical qubits, which are essential for implementation of any practical quantum computational task, have not been experimentally demonstrated yet. Here we demonstrate a geometric method for realizing controlled-phase gates between two logical qubits encoded in photonic fields stored in cavities. The gates are realized by dispersively coupling an ancillary superconducting qubit to these cavities and driving it to make a cyclic evolution depending on the joint photonic state of the cavities, which produces a conditional geometric phase. We first realize phase gates for photonic qubits with the logical basis states encoded in two quasiorthogonal coherent states, which have important implications for continuous-variable-based quantum computation. Then we use this geometric method to implement a controlled-phase gate between two binomially encoded logical qubits, which have an error-correctable function.

Abstract
Maize is currently the most important crop in China. A major concern in maize production is maize ear rot caused by Fusarium spp., which results in yield losses, reduction of seed quality and the accumulation of mycotoxins in the harvested grains. To identify the importance of the different Fusarium species in maize infection, we performed a comprehensive survey on 9,000 asymptomatic and randomly collected maize kernels. Seeds were collected from 12 different provinces covering all major maize growing areas in China and included five maize varieties. In total 1,022 Fusarium isolates were retrieved that were identified based on morphological characteristics, by species specific diagnostic PCRs and by EF1-α gene sequencing. Eight different species were identified: Fusarium verticillioides (75.34%), Fusarium graminearum (8.32%), Fusarium proliferatum (7.14%), Fusarium subglutinans (4.11%), Fusarium meridionale (1.57%), Fusarium oxysporum (1.37%), Fusarium semitectum (1.17%), and Fusarium asiaticum (0.98%). The distribution of Fusarium species was found to be different in different regions with the largest diversity observed in Hubei province, where all eight Fusarium species were isolated. Genetic chemotyping within the F. graminearum species complex indicated that all of the 85 F. graminearum isolates showed the 15-acetyldeoxynivalenol chemotype, whereas all F. asiaticum (n=10) and F. meridionale (n=16) isolates had the nivalenol chemotype even when isolated from the same maize field. To our knowledge this is the largest collection of Fusarium isolates from maize and further exploitations of this collection are discussed.

Safety, feasibility, and effect of an enhanced nutritional support pathway including extended preoperative and home enteral nutrition in patients undergoing enhanced recovery after esophagectomy: a pilot randomized clinical trial. Dis Esophagus 2020; 33:5479246. [PMID: 31329828 DOI: 10.1093/dote/doz030] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2018] [Revised: 03/08/2019] [Accepted: 03/13/2019] [Indexed: 12/11/2022]
Abstract
The aims of this pilot study are to evaluate the feasibility, safety, and effectiveness of conducting an enhanced nutritional support pathway including extended preoperative nutritional support and one month home enteral nutrition (HEN) for patients who underwent enhanced recovery after esophagectomy. We implemented extended preoperative nutritional support and one month HEN after discharge for patients randomized into an enhanced nutrition group and implemented standard nutritional support for patients randomized into a conventional nutrition group. Except the nutritional support program, both group patients underwent the same standardized enhanced recovery after surgery programs of esophagectomy based on published guidelines. Patients were assessed at preoperative day, postoperative day 7 (POD7), and POD30 for perioperative outcomes and nutritional status. To facilitate the determination of an effect size for subsequent appropriately powered randomized clinical trials and assess the effectiveness, the primary outcome we chose was the weight change before and after esophagectomy. Other outcomes including body mass index (BMI), lean body mass (LBM), appendicular skeletal muscle mass index (ASMI), nutrition-related complications, and quality of life (QoL) were also analyzed. The intention-to-treat analysis of the 50 randomized patients showed that there was no significant difference in baseline characteristics. The weight (-2.03 ± 2.28 kg vs. -4.05 ± 3.13 kg, P = 0.012), BMI (-0.73 ± 0.79 kg/m2 vs. -1.48 ± 1.11 kg/m2, P = 0.008), and ASMI (-1.10 ± 0.37 kg/m2 vs. -1.60 ± 0.66 kg/m2, P = 0.010) loss of patients in the enhanced nutrition group were obviously decreased compared to the conventional nutrition group at POD30. In particular, LBM (48.90 ± 9.69 kg vs. 41.96 ± 9.37 kg, p = 0.031) and ASMI (7.56 ± 1.07 kg/m2 vs. 6.50 ± 0.97 kg/m2, P = 0.003) in the enhanced nutrition group were significantly higher compared to the conventional nutrition group at POD30, despite no significant change between pre- and postoperation. In addition, European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 scores revealed that enhanced nutritional support improved the QoL of patients in physical function (75.13 ± 9.72 vs. 68.33 ± 7.68, P = 0.009) and fatigue symptom (42.27 ± 9.93 vs. 49.07 ± 11.33, P = 0.028) compared to conventional nutritional support. This pilot study demonstrated that an enhanced nutritional support pathway including extended preoperative nutritional support and HEN was feasible, safe, and might be beneficial to patients who underwent enhanced recovery after esophagectomy. An appropriately powered trial is warranted to confirm the efficacy of this approach.

Abstract
Vascular cognitive impairment (VCI) plays an important role in dementia in elderly people, and refers to the contribution of vascular pathology to the entire spectrum of cognitive disorders, ranging from mild cognitive impairment to severe dementia, as well as the pathological spectrum, from 'pure' Alzheimer disease through degrees of vascular comorbidity to 'pure' vascular dementia. In the present study, we investigated the relationship between cognitive dysfunction and systemic metabolic disorders, by employing deep learning (DL). We studied 202 patients (73.4 ± 13.0 years), 94.6% of whom were undergoing treatment for lifestyle diseases, and 68.8% of whom had a history of cerebrovascular disorder. We evaluated cognitive dysfunction by performing a Mini Mental State Examination (MMSE). We performed general blood examination, including Complete Blood Count and Basic Metabolic Panel, and measured cerebral blood oxygenation in the prefrontal cortex (PFC) using time-resolved near infrared spectroscopy (TNIRS). We then used deep neural networks to assess the MMSE scores of the subjects based on the TNIRS parameters and the blood examination data, independently. Next, we compared predicted MMSE scores based on the TNIRS and the blood examination. There was a significant positive correlation between the TNIRS parameters and the blood examination data (r = 0.6, p < 0.01). These observations suggest that cognitive dysfunction in patients with VCI may be caused by combinations of systemic metabolic disorders such as energy and oxygen metabolisms and cerebral circulatory disturbance due to arteriosclerosis resulting from lifestyle-related diseases.

Abstract
OBJECTIVE MLN4924 is a second-generation small molecule inhibitor with anti-cancer activity that inhibits neddylation activation enzyme (NAE), subsequently blocking the neddylation-dependent activation of Cullin-RING E3 ligases (CRLs). Mof4 family associated protein 1 (MRFAP1) is a highly conserved, short half-life protein and one of the most up-regulated proteins in response to MLN4924 treatment. MRFAP1 has been identified as a novel cell cycle-related protein and a regulatory component monitoring and preventing genomic instability. However, whether MRFAP1 plays a role in MLN4924-mediated cancer cell death remains elusive. PATIENTS AND METHODS The expression of MRFAP1 in gastric cancer clinic samples was detected by Real-time PCR and Western blot. CRISPR (clustered regularly interspaced short palindromic repeats)/Cas9 system was used to knockout MRFAP1 gene in both AGS and SGC-7901 cells. The proliferation of GC cells was measured by CCK8 assay. The cell cycle distribution of GC cells was determined by fluorescence-activated cell sorting (FACS) assay. Co-immunoprecipitation assay was used to determine the interaction between MRFAP1 and P27. RESULTS MRFAP1 was downregulated in clinic gastric cancer samples at post-translational level. Overexpression of MRFAP1 decreased gastric cancer cells proliferation. CRISPR-mediated knockout of MRFAP1 increased the cytotoxicity of MLN4924 by augmenting MLN4924-induced G2/M arrest and apoptosis against gastric cancer cells. At the molecular level, we found that MLN4924 induced the interaction between P27 and MRFAP1, the latter associated with P27, which was further stabilized in response to MLN4924 treatment. CONCLUSIONS We showed a protective role of MRFAP1 in gastric cancer cells with MLN4924 treatment and suggested the potential possibility to combine MLN4924 with MRFAP1 inhibition to treat gastric cancer.

Abstract
BACKGROUND HOTAIR is a variety of long non-coding RNA that has been recognized as a predictive factor for most cancers. This meta-analysis examined the complete investigative effectiveness of the level of HOTAIR expression for various cancers. METHODS Research on the diagnostic value of HOTAIR in different carcinomas was acquired by searching the online databases. Twelve studies consisting of 927 cancer cases were chosen in our research. The sensitivity as well as specificity of the involved articles was helpful to establish the summary receiver operator characteristic (SROC) curve in addition to compute the area under the SROC curve (AUC). In addition, a meta-regression test was done to determine the heterogeneity sources among available studies. RESULTS The combined effect sizes calculated from involved studies were as follows: sensitivity, 0.73; specificity, 0.83; PLR, 4.4; NLR, 0.32; DOR, 14; and an AUC of 0.85. Deeks' funnel plot asymmetry test showed no probable publication bias. The meta-regression analyses signified that the type of ethnicity is the major cause of heterogeneity. CONCLUSIONS The present meta-analysis suggested that elevated HOTAIR can be considered as a relatively accurate marker for cancer diagnosis and can be applied to support the diagnosis of various cancers.
