Abstract
OBJECTIVE Acute kidney injury (AKI) is difficult to detect in the early stages, yet is commonly associated with sepsis and infectious shock, with pulmonary infection being the most frequent culprit. This study aimed to estimate risk factors and their effects on 28-day survival among sepsis patients with pulmonary infection complicated by AKI and assessed the prognostic values of some detection indicators. PATIENTS AND METHODS From February 2019 to July 2021, the data of 151 patients admitted to the emergency intensive care unit (EICU) of Nanjing First Hospital with pulmonary infection complicated with sepsis were collected in this retrospective study. The patients were categorized into two groups (survivors and non-survivors) depending on the 28-day survival, compared their clinical characteristics, and analyzed the predictors of survival. RESULTS Cox regression analysis revealed that serum cystatin-C level, serum lactate level, and the Acute Physiology and Chronic Health Evaluation II (APACHE II) scoring system were independent risk factors for 28-day survival. In predicting 28-day survival, the area under the receiver operating characteristic curve (ROC) for serum Cystatin-C level, serum lactate level, APACHE II score, and the three combinations was 0.74, 0.67, 0.71, and 0.86, respectively. Accordingly, the sensitivity and specificity of the three indicators of 28-day survival were 87.50% and 66.67%, respectively, which were superior to individual indicators. CONCLUSIONS Sepsis patients with pulmonary infection have a high risk of AKI, and multiple risk factors contribute to this risk. AKI patients may also be adversely affected by a variety of factors, including APACHE II scores, serum Cystatin-C levels, and serum lactate levels, all of which are commonly used to assess the outcomes.

Abstract
PURPOSE/OBJECTIVE(S) To assess the safety and efficacy of intensity-modulated radiotherapy (IMRT) combined with nimotuzumab for patients with locally advanced nasopharyngeal carcinoma (LA-NPC) medically unfit to receive concomitant chemotherapy. MATERIALS/METHODS From 2016.6 to 2020.9, 34 newly diagnosed patients with local-regional advanced NPC medically unfit for concurrent chemoradiation had undergone definitive radiotherapy and were retrospectively evaluated. All patients were treated with IMRT combined treatment modality of nimotuzumab with or without cisplatin-based induction chemotherapy. Nimotuzumab was administered concurrently with IMRT at a weekly dose of 200 mg. Acute and late radiation-related toxicities were evaluated based on the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 during and after IMRT. The Kaplan-Meier method was used for survival analysis. Univariate and multivariate prognostic analyses were performed by using the Cox proportional hazard model. RESULTS The median follow-up time for the entire group was 15 months (range 5 to 55 months). At the time of this analysis, a total of 2 cases developed loco-regional recurrence. In addition, 4 patients developed distant metastasis. There was a total of 5 deaths: 3 patients died from distant metastasis, 1 patient died from the progression of loco-regional disease after recurrence, and the causes of death for the additional 1 case was a nasopharyngeal ulcer and deadly bleeding. The 1-year OS rate of the whole cohort was 87.9%, and the 1-year LFFR, DFFR, and PFS rates were 100%, 91.0%, and 91.0%, respectively. During the period of concurrent nimotuzumab and IMRT, no grade 3-4 hematologic toxicities and dermatitis were observed. Grade 3-4 radiotherapy-related oral mucositis was reported in 7 patients (20.6%). No infusion reaction was observed. No acneiform eruptions were found among these patients. The most commonly observed late complication was xerostomia. The degree of dry mouth in most patients was mild-to-moderate at the time of the last follow-up. Finally, 7 patients developed either unilateral or bilateral hearing impairment. One female patient experienced a nasopharyngeal ulcer and deadly bleeding after 5 months of completion of radiotherapy. CONCLUSION Concurrent nimotuzumab with IMRT for the treatment of LA-NPC was well tolerated, with encouraging survival data, and it could be an effective treatment alternative for patients with LA-NPC medically unfit for concomitant chemotherapy. Further clinical trials are needed to confirm these findings.

Abstract
PURPOSE/OBJECTIVE(S) Recent studies indicate that the novel lymphocyte-C-reactive protein ratio (LCR) is strongly associated with the survival of various tumors, but its prognostic value in nasopharyngeal carcinoma (NPC) is understudied. This study aimed to explore the relationship between the LCR and overall survival (OS) in NPC and to develop a predictive model. MATERIALS/METHODS A total of 841 NPC patients received concurrent chemoradiotherapy (CCRT) were retrospectively enrolled and randomly divided into training cohort (n = 589) and validation cohort (n = 252). Univariate and multivariate Cox analyses were performed to identify variables associated with OS and construct a predictive nomogram. The predictive accuracy of the nomogram was evaluated and independently validated. RESULTS The LCR score differentiated NPC patients into two groups with distinct prognoses (HR = 0.53; 95% CI: 0.32-0.89, P = 0.014). Multivariate analysis showed that age, T stage, N stage, EBV-DNA status, and LCR score were independently associated with OS and a predictive nomogram was developed. The nomogram had a good performance for the prediction of OS [C-index = 0.770 (95% CI: 0.675-0.864)] and outperformed the traditional staging system [C-index = 0.589 (95% CI: 0.385-0.792)]. The results were internally validated using an independent cohort. CONCLUSION The novel nutrition-inflammation marker of LCR could serve as a simplified, affordable, easy-to-obtain, non-invasive, and readily promotive prognostic marker for NPC patients received CCRT, and the LCR-based prognostic nomogram outperformed the conventional staging system in terms of predictive power.

Abstract
Rational design of chimeric antigen receptor T (CAR-T) cells based on the recognition of antigenic epitopes capable of evoking the most potent CAR activation is an important objective in optimizing immune therapy. In solid tumors, the B7-H3 transmembrane protein is an emerging target that harbours two distinct epitope motifs, IgC and IgV, in its ectodomain. Here, we generate dromedary camel nanobodies targeting B7-H3 and demonstrate that CAR-T cells, based on the nanobodies recognizing the IgC but not IgV domain, had potent antitumour activity against large tumors in female mice. These CAR-T cells are characterized by highly activated T cell signaling and significant tumor infiltration. Single-cell transcriptome RNA sequencing coupled with functional T-cell proteomics analysis uncovers the top-upregulated genes that might be critical for the persistence of polyfunctional CAR-T cells in mice. Our results highlight the importance of the specific target antigen epitope in governing optimal CAR-T activity and provide a nanobody-based B7-H3 CAR-T product for use in solid tumor therapy.

Abstract
Objective: To analyze the incidence and risk factors of ventricular septal defect (VSD) in Qingdao. Methods: A prospective cohort study design was used to include pregnant women who underwent prenatal screening in Qingdao between August 2018 and June 2020 (the whole population coverage). VSD was diagnosed according to the pulse oxygen saturation and heart auscultation, and the final diagnosis was made according to the echocardiography of VSD positive newborns within postnatal day 7. Results: The study included 115 238 live births, among which 388 were diagnosed as VSD, with an incidence of 3.37‰. The results of multivariate logistic regression analysis showed that mother with postgraduate level (OR=1.61, 95%CI: 1.00-2.58, P=0.049) (compared with junior high school and below), preterm birth history (OR=2.90, 95%CI: 1.47-5.70, P=0.002), and pregnancy history of congenital heart disease (OR=5.98, 95%CI: 2.63-14.73, P<0.001) were risk factors for VSD. Compared with female infants, the overall risk of VSD in male infants was relatively low (OR=0.74, 95%CI: 0.60-0.91, P=0.005). Conclusions: The incidence of VSD in Qingdao is 3.37‰. The risk factors of VSD include higher maternal education level, pregnancy history of congenital heart disease and preterm birth history. Moreover, the overall risk of VSD in male infants is low.

Abstract
Clinically relevant immunological biomarkers that discriminate between diverse hypofunctional states of tumor-associated CD8+ T cells remain disputed. Using multiomics analysis of CD8+ T cell features across multiple patient cohorts and tumor types, we identified tumor niche-dependent exhausted and other types of hypofunctional CD8+ T cell states. CD8+ T cells in "supportive" niches, like melanoma or lung cancer, exhibited features of tumor reactivity-driven exhaustion (CD8+ TEX). These included a proficient effector memory phenotype, an expanded T cell receptor (TCR) repertoire linked to effector exhaustion signaling, and a cancer-relevant T cell-activating immunopeptidome composed of largely shared cancer antigens or neoantigens. In contrast, "nonsupportive" niches, like glioblastoma, were enriched for features of hypofunctionality distinct from canonical exhaustion. This included immature or insufficiently activated T cell states, high wound healing signatures, nonexpanded TCR repertoires linked to anti-inflammatory signaling, high T cell-recognizable self-epitopes, and an antiproliferative state linked to stress or prodeath responses. In situ spatial mapping of glioblastoma highlighted the prevalence of dysfunctional CD4+:CD8+ T cell interactions, whereas ex vivo single-cell secretome mapping of glioblastoma CD8+ T cells confirmed negligible effector functionality and a promyeloid, wound healing-like chemokine profile. Within immuno-oncology clinical trials, anti-programmed cell death protein 1 (PD-1) immunotherapy facilitated glioblastoma's tolerogenic disparities, whereas dendritic cell (DC) vaccines partly corrected them. Accordingly, recipients of a DC vaccine for glioblastoma had high effector memory CD8+ T cells and evidence of antigen-specific immunity. Collectively, we provide an atlas for assessing different CD8+ T cell hypofunctional states in immunogenic versus nonimmunogenic cancers.

Abstract
Heterogeneous antigen expression is a key barrier influencing the activity of chimeric antigen receptor (CAR) T cells in solid tumors. Here, we develop CAR T cells targeting glypican-1 (GPC1), an oncofetal antigen expressed in pancreatic cancer. We report the generation of dromedary camel VHH nanobody (D4)-based CAR T cells targeting GPC1 and the optimization of the hinge (H) and transmembrane domain (TM) to improve activity. We find that a structurally rigid IgG4H and CD28TM domain brings the two D4 fragments in proximity, driving CAR dimerization and leading to enhanced T-cell signaling and tumor regression in pancreatic cancer models with low antigen density in female mice. Furthermore, single-cell-based proteomic and transcriptomic analysis of D4-IgG4H-CD28TM CAR T cells reveals specific genes (e.g., HMGB1) associated with high T-cell polyfunctionality. This study demonstrates the potential of VHH-based CAR T for pancreatic cancer therapy and provides an engineering strategy for developing potent CAR T cells targeting membrane-distal epitopes.

Abstract
Genetically and phenotypically identical immune cell populations can be highly heterogenous in terms of their immune functions and protein secretion profiles. The microfluidic chip-based single-cell highly multiplexed secretome proteomics enables characterization of cellular heterogeneity of immune responses at different cellular and molecular layers. Increasing evidence has demonstrated that polyfunctional T cells that simultaneously produce 2+ proteins per cell at the single-cell level are key effector cells that contribute to the development of potent and durable cellular immunity against pathogens and cancers. The functional proteomic technology offers a wide spectrum of cellular function assessment and can uniquely define highly polyfunctional cell subsets with cytokine signatures from live individual cells. This high-dimensional single-cell analysis provides deep dissection into functional heterogeneity and helps identify predictive biomarkers and potential correlates that are crucial for immunotherapeutic product design optimization and personalized immunotherapy development to achieve better clinical outcomes.

Abstract
AIMS We aimed to investigate the association between residential greenness and MetS in older Chinese adults. METHODS Longitudinal data on sociodemographic characteristics and lifestyle were collected from the Shenzhen Healthy Ageing Research (SHARE) cohort. Greenness exposure was assessed through satellite-derived Normalized Difference Vegetation Index (NDVI) values in the 250-m, 500-m, and 1250-m radius around the residential address for each participant. MetS was defined by standard guidelines for the Chinese population. RESULTS A total of 49,893 older Chinese adults with a mean age of 70.96 (SD = 5.26) years were included in the study. In the fully adjusted models, participants who lived in the highest quartile of NDVI250-m, NDVI500-m, and NDVI1250-m had a 15% (odds ratio, OR = 0.85, 95% confidence interval, CI: 0.80-0.90), 12% (OR = 0.88, 95% CI: 0.83-0.93), and 11% (OR = 0.89, 95% CI: 0.85-0.95) lower incidence of MetS, respectively, than those living in the lowest quartile (all p-trend < 0.01). Interactions and subgroup analyses showed that age, sex, smoking status, and drinking status were significant effect modifiers (p-interaction for all NDVI < 0.05). CONCLUSIONS Residential greenness is associated with a lower risk of MetS in Chinese older adults, especially for young older adults, females, non-smokers, and non-drinkers.

Abstract
OBJECTIVE Previous studies on residential green space were inconsistent with blood lipid levels and hyperlipidemia. Thus, our study aims to explore the relationship between urban residential greenness and the blood lipid level and hyperlipidemia of the Chinese elderly population. METHODS A total of 59,865 older adults were collected from the Shenzhen healthy aging Research (SHARE). Blood lipid levels [total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C)] were measured. Participants' exposure to residential greenness was measured by the satellite-based normalized difference vegetation index (NDVI). Generalized linear mixed models (GLMMs) and logistic regression were performed to assess the associations of residential greenness with lipid levels and dyslipidemia (high TG, high TC, low HDL-C, and high LDL-C). RESULTS Each per 1 standard deviation (SD) increase in NDVI250-m was associated with a higher HDL-C level (β = 0.003, 95% (confidence interval, CI):0.001-0.005) and lower TG level (β = - 0.005, 95% CI - 0.141-0.121), after fully adjusting for covariates. Each increment in per interquartile range (IQR)-unit increase in NDVI250-m was associated with lower odds of high TG (odds ratio, OR 0.94, 95% CI 0.91-0.97) and low HDL-C (OR 0.96, 95% CI 0.94-0.99). The NDVI250-m has the highest protective effect on the incidence of high TG and low HDL-C, followed by NDVI500-m and NDVI1250-m. Stratified analyses showed that association between residential greenness and hyperlipidemia was modified by sex, age, BMI, household registration, and physical activity. CONCLUSION Higher greenness exposure was beneficially associated with lipid levels and dyslipidemia among Chinese city-dwelling older adults.

Abstract
BACKGROUND The mechanisms regulating CD8+ T cell migration to nonlymphoid tissue during inflammation have not been fully elucidated, and the migratory properties of effector memory CD8+ T cells that re-express CD45RA (TEMRA CD8+ T cells) remain unclear, despite their roles in autoimmune diseases and allotransplant rejection. METHODS We used single-cell proteomic profiling and functional testing of CD8+ T cell subsets to characterize their effector functions and migratory properties in healthy volunteers and kidney transplant recipients with stable or humoral rejection. RESULTS We showed that humoral rejection of a kidney allograft is associated with an accumulation of cytolytic TEMRA CD8+ T cells in blood and kidney graft biopsies. TEMRA CD8+ T cells from kidney transplant recipients exhibited enhanced migratory properties compared with effector memory (EM) CD8+ T cells, with enhanced adhesion to activated endothelium and transmigration in response to the chemokine CXCL12. CXCL12 directly triggers a purinergic P2×4 receptor-dependent proinflammatory response of TEMRA CD8+ T cells from transplant recipients. The stimulation with IL-15 promotes the CXCL12-induced migration of TEMRA and EM CD8+ T cells and promotes the generation of functional PSGL1, which interacts with the cell adhesion molecule P-selectin and adhesion of these cells to activated endothelium. Although disruption of the interaction between functional PSGL1 and P-selectin prevents the adhesion and transmigration of both TEMRA and EM CD8+ T cells, targeting VLA-4 or LFA-1 (integrins involved in T cell migration) specifically inhibited the migration of TEMRA CD8+ T cells from kidney transplant recipients. CONCLUSIONS Our findings highlight the active role of TEMRA CD8+ T cells in humoral transplant rejection and suggest that kidney transplant recipients may benefit from therapeutics targeting these cells.

Abstract
Cadmium, which is widely used in electroplating industry, chemical industry, electronic industry and nuclear industry, is harmful to human health and ecological environment. The effects of Cd at different initial concentrations on biomass, antioxidant enzyme activity and ultrastructure of Chlorella vulgaris were analysed in the present study. The results showed that C. vulgaris maintained a slow-growth trend at 3.0 mg/L Cd, and the peroxidase (POD) enzyme activity reached the highest at this concentration, which indicated that C. vulgaris could resist the oxidative damage of cells by increasing the enzyme activity, so as to improve the tolerance of C. vulgaris to Cd. When the concentration of Cd was 5.0 mg/L, although the activity of the superoxide dismutase enzyme was still very high, POD enzyme could not remove the hydrogen peroxide produced in cells in time, leading to cell damage and even death. Therefore, when the concentration reached 5.0 mg/L, the growth of C. vulgaris began to decline after four days of stress, and the cell structure was significantly damaged after six days of stress. And the higher concentration of Cd caused more Cd accumulation in cells and a serious damage to C. vulgaris. C. vulgaris can be used as an early warning indicator of Cd pollution, and it can be used for bioremediation of Cd contaminated water through tolerant subculture.

Abstract
Amyotrophic lateral sclerosis (ALS) is an auto-immune neurodegenerative disorder affecting the motor-neuron system. The causes of ALS are heterogeneous, and are only partially understood. We studied different aspects of immune pathogenesis in ALS and found several basic mechanisms which are potentially involved in the disease. Our findings demonstrated that ALS patients' peripheral blood contains higher proportions of NK and B cells in comparison to healthy individuals. Significantly increased IFN-γ secretion by anti-CD3/28 mAbs-treated peripheral blood mononuclear cells (PBMCs) were observed in ALS patients, suggesting that hyper-responsiveness of T cell compartment could be a potential mechanism for ALS progression. In addition, elevated granzyme B and perforin secretion at a single cell level, and increased cytotoxicity and secretion of IFN-γ by patients' NK cells under specific treatment conditions were also observed. Increased IFN-γ secretion by ALS patients' CD8+ T cells in the absence of IFN-γ receptor expression, and increased CD8+ T cell effector/memory phenotype as well as increased granzyme B at the single cell level points to the CD8+ T cells as potential cells in targeting motor neurons. Along with the hyper-responsiveness of cytotoxic immune cells, significantly higher levels of inflammatory cytokines including IFN-γ was observed in peripheral blood-derived serum of ALS patients. Supernatants obtained from ALS patients' CD8+ T cells induced augmented cell death and differentiation of the epithelial cells. Weekly N-acetyl cysteine (NAC) infusion in patients decreased the levels of many inflammatory cytokines in peripheral blood of ALS patient except IFN-γ, TNF-α, IL-17a and GMCSF which remained elevated. Findings of this study indicated that CD8+ T cells and NK cells are likely culprits in targeting motor neurons and therefore, strategies should be designed to decrease their function, and eliminate the aggressive nature of these cells. Analysis of genetic mutations in ALS patient in comparison to identical twin revealed a number of differences and similarities which may be important in the pathogenesis of the disease.

Abstract
With the increasing global aging population, the health of the elderly has become a global concern. Accidental falls, as one of the major causes of health and safety issues affecting the elderly, can cause serious hazards. In this paper, a fall detection system is proposed to be able to deliver timely information after a fall. The acceleration and angular velocity time series extracted from motion were used to describe human motion features. Hybrid threshold analysis algorithm and machine learning algorithm are used for classification between falls and activities of daily living (ADLs). The fall detection results showed 98.55% accuracy, 98.16% sensitivity, and 98.73% specificity. The result is higher than the single-threshold algorithm and slightly lower than the machine learning algorithm. In addition, the hybrid algorithm of fall detection in this paper is to put the threshold analysis algorithm in the edge device for calculation and put the machine learning algorithm in the cloud server for calculation. Since the single machine learning algorithm needs to transmit data to the cloud server all the time, the hybrid algorithm has lower power consumption than machine learning algorithms, and the average alarm time is shorter, making it more suitable for actual systems.

Abstract
UNLABELLED This retrospective analysis of insurance claims evaluated real-world trends in prescription fills among patients treated with balloon kyphoplasty (N = 6,656) or vertebroplasty (N = 2,189) following diagnosis of vertebral compression fracture. Among those with evidence of opioid use, nearly half of patients discontinued or reduced prescription fills relative to pre-operative levels. INTRODUCTION Vertebral compression fractures (VCF) are associated with debilitating pain, spinal misalignment, increased mortality, and increased healthcare-resource utilization in elderly patients. This study evaluated the effect of balloon kyphoplasty (BKP) or vertebroplasty (VP) on post-procedure opioid prescription fills and payer costs in patients with VCF. METHODS This was a retrospective analysis of a large, nationally representative insurance-claims database. Clinical characteristics, opioid prescription patterns, and payer costs for subjects who underwent either BKP or VP to treat VCF were evaluated beginning 6 months prior to surgery through 7-month follow-up that included a 30-day, postoperative medication washout. Patient demographics, changes in opioid utilization, and payer costs were analyzed. RESULTS A total of 8,845 patients met eligibility criteria (75.3% BKP and 24.7% VP) with a mean of age 77 and 74% female. Among the 75% of patients who used opioids, 48.7% of patients discontinued opioid medication and 8.4% reduced prescription fills versus preoperative baseline. Patients who reduced or discontinued prescriptions exhibited a decrease in all-cause payer costs relative to pre-intervention levels, which was a significantly greater change relative to patients with no change, increase, or new start of opioids. CONCLUSIONS Interventional treatment for VCF was associated with decreased or discontinued opioid prescription fills and reduced payer costs in follow-up in a significant proportion of the study population. Reduction of opioid-based harms may represent a previously unrecognized benefit of vertebral augmentation for VCF, especially in this elderly and medically fragile population.

Abstract
Overwhelming inflammation in the setting of acute critical illness induces capillary leak resulting in hypovolemia, edema, tissue dysoxia, organ failure and even death. The tight junction (TJ)-dependent capillary barrier is regulated by small GTPases, but the specific regulatory molecules most active in this vascular segment under such circumstances are not well described. We set out to identify GTPase regulatory molecules specific to endothelial cells (EC) that form TJs. Transcriptional profiling of confluent monolayers of TJ-forming human dermal microvascular ECs (HDMECs) and adherens junction only forming-human umbilical vein EC (HUVECs) demonstrate ARHGEF12 is basally expressed at higher levels and is only downregulated in HDMECs by junction-disrupting tumor necrosis factor (TNF). HDMECs depleted of ArhGEF12 by siRNA demonstrate a significantly exacerbated TNF-induced decrease in trans-endothelial electrical resistance and disruption of TJ continuous staining. ArhGEF12 is established as a RhoA-GEF in HUVECs and its knock down would be expected to reduce RhoA activity and barrier disruption. Pulldown of active GEFs from HDMECs depleted of ArhGEF12 and treated with TNF show decreased GTP-bound Rap1A after four hours but increased GTP-bound RhoA after 12 h. In cell-free assays, ArhGEF12 immunoprecipitated from HDMECs is able to activate both Rap1A and RhoA, but not act on Rap2A-C, RhoB-C, or even Rap1B which shares 95% sequence identity with Rap1A. We conclude that in TJ-forming HDMECs, ArhGEF12 selectively activates Rap1A to limit capillary barrier disruption in a mechanism independent of cAMP-mediated Epac1 activation.

Abstract
OBJECTIVES To comprehensively evaluate the association between BMI and death risk in people aged 65 years and over in Shenzhen, China, and suggest the optimal range of body mass index (BMI) for the older adults. DESIGN A prospective cohort study. SETTING A population-based study of elderly adults in Shenzhen, China. PARTICIPANTS 359044 Shenzhen Healthy Ageing Research participants aged 65 and over with 4682 deaths during a mean of 1.5 years of follow-up were included in this analysis. MEASURES Hazard ratio of all-cause and cause specific mortality risks associated with BMI categories. The association between BMI and all-cause and cause specific mortality were independently estimated by Cox regression model. RESULTS Regardless of gender, BMI of 24 -29.9 kg/m2 was a protective factor for death in all ages, while BMI above 30 kg/m2 was still a protective factor for older adults under 70 years old. Regardless of age, BMI at 24-25.9 kg/m2 was associated with lower mortality in men, while BMI at 26-27.9 kg/m2 was associated with lower mortality in women. For the older adults without chronic diseases, BMI at 24-25.9 kg/m2 was also significantly associated with lower mortality. In the analysis of BMI and cause of death, we also found that BMI of 24-25.9 kg/m2 was significantly associated with the lower mortality from cardiovascular disease, cancer, chronic respiratory disease and digestive system disease in China. CONCLUSION BMI in the range of 24-25.9 kg/m2 may be protective for mortality in Chinese older adults. Additional more large-scale, multicenter and long-term follow-up studies are needed to confirm these findings in different populations.

Abstract
Capillary endothelial cells (ECs) maintain a semi-permeable barrier between the blood and tissue by forming inter-EC tight junctions (TJs), regulating selective transport of fluid and solutes. Overwhelming inflammation, as occurs in sepsis, disrupts these TJs, leading to leakage of fluid, proteins, and small molecules into the tissues. Mechanistically, disruption of capillary barrier function is mediated by small Rho-GTPases, such as RhoA, -B, and -C, which are activated by guanine nucleotide exchange factors (GEFs) and disrupted by GTPase-activating factors (GAPs). We previously reported that a mutation in a specific RhoB GAP (p190BRhoGAP) underlays a hereditary capillary leak syndrome. Tumor necrosis factor (TNF) treatment disrupts TJs in cultured human microvascular ECs, a model of capillary leak. This response requires new gene transcription and involves increased RhoB activation. However, the specific GEF that activates RhoB in capillary ECs remains unknown. Transcriptional profiling of cultured tight junction-forming human dermal microvascular endothelial cells (HDMECs) revealed that 17 GEFs were significantly induced by TNF. The function of each candidate GEF was assessed by short interfering RNA depletion and trans-endothelial electrical resistance screening. Knockown of ArhGEF10 reduced the TNF-induced loss of barrier which was phenocopied by RhoB or dual ArhGEF10/RhoB knockdown. ArhGEF10 knockdown also reduced the extent of TNF-induced RhoB activation and disruption at tight junctions. In a cell-free assay, immunoisolated ArhGEF10 selectively catalyzed nucleotide exchange to activate RhoB, but not RhoA or RhoC. We conclude ArhGEF10 is a TNF-induced RhoB-selective GEF that mediates TJ disruption and barrier loss in human capillary endothelial cells.

Abstract
Membrane distillation technology, as a new membrane-based water treatment technology that combines the membrane technology and evaporation process, has the advantages of using low-grade heat, working at atmospheric pressure with simple configuration, etc. In this study, heat and mass transfer were coupled at the membrane surfaces through the user-defined function program. The effects of feed temperature, feed velocity and permeate velocity on temperature polarization were mainly investigated for a high-concentration NaCl solution. The temperature polarization was increased with the increase of feed temperature and the decrease of feed and permeate velocity. The effects of temperature, inlet velocity and solution concentration on the evaporation efficiency of the membrane module for co- and counter-current operations were investigated in detail. The counter-current operation performed better than co-current operation in most cases, except for the condition where the NaCl concentration was relatively low or the module length was long enough. In addition, the optimal membrane thickness for both PVDF and PTFE was studied. The optimal membrane thickness was found in the range of 10 to 20 μm, which corresponded to the highest permeate flux for the selected materials, pore size distribution, and operation conditions. Membrane material with lower thermal conductivity and larger porosity was prone to get higher permeate flux and had larger optimal membrane thickness. Increasing feed velocity or feed temperature could decrease the optimal membrane thickness.

Abstract
Excessive visceral fat accumulation is a primary risk factor for metabolically unhealthy obesity and related diseases. The visceral fat is highly susceptible to the availability of external nutrients. Nutrient flux into the hexosamine biosynthetic pathway leads to protein posttranslational modification by O-linked β-N-acetylglucosamine (O-GlcNAc) moieties. O-GlcNAc transferase (OGT) is responsible for the addition of GlcNAc moieties to target proteins. Here, we report that inducible deletion of adipose OGT causes a rapid visceral fat loss by specifically promoting lipolysis in visceral fat. Mechanistically, visceral fat maintains a high level of O-GlcNAcylation during fasting. Loss of OGT decreases O-GlcNAcylation of lipid droplet-associated perilipin 1 (PLIN1), which leads to elevated PLIN1 phosphorylation and enhanced lipolysis. Moreover, adipose OGT overexpression inhibits lipolysis and promotes diet-induced obesity. These findings establish an essential role for OGT in adipose tissue homeostasis and indicate a unique potential for targeting O-GlcNAc signaling in the treatment of obesity.

Abstract
RATIONALE BMX (bone marrow kinase on the X chromosome) is highly expressed in the arterial endothelium from the embryonic stage to the adult stage in mice. It is also expressed in microvessels and the lymphatics in response to pathological stimuli. However, its role in endothelial permeability and sepsis remains unknown. OBJECTIVE We aimed to delineate the function of BMX in thrombin-mediated endothelial permeability and the vascular leakage that occurs with sepsis in cecal ligation and puncture models. METHODS AND RESULTS The cecal ligation and puncture model was applied to WT (wild type) and BMX-KO (BMX global knockout) mice to induce sepsis. Meanwhile, the electric cell-substrate impedance sensing assay was used to detect transendothelial electrical resistance in vitro and, the modified Miles assay was used to evaluate vascular leakage in vivo. We showed that BMX loss caused lung injury and inflammation in early cecal ligation and puncture-induced sepsis. Disruption of BMX increased thrombin-mediated permeability in mice and cultured endothelial cells by 2- to 3-fold. The expression of BMX in macrophages, neutrophils, platelets, and lung epithelial cells was undetectable compared with that in endothelial cells, indicating that endothelium dysfunction, rather than leukocyte and platelet dysfunction, was involved in vascular permeability and sepsis. Mechanistically, biochemical and cellular analyses demonstrated that BMX specifically repressed thrombin-PAR1 (protease-activated receptor-1) signaling in endothelial cells by directly phosphorylating PAR1 and promoting its internalization and deactivation. Importantly, pretreatment with the selective PAR1 antagonist SCH79797 rescued BMX loss-mediated endothelial permeability and pulmonary leakage in early cecal ligation and puncture-induced sepsis. CONCLUSIONS Acting as a negative regulator of PAR1, BMX promotes PAR1 internalization and signal inactivation through PAR1 phosphorylation. Moreover, BMX-mediated PAR1 internalization attenuates endothelial permeability to protect vascular leakage during early sepsis.

Abstract
Cancer cells are known to adopt aerobic glycolysis in order to fuel tumor growth, but the molecular basis of this metabolic shift remains largely undefined. O-GlcNAcase (OGA) is an enzyme harboring O-linked β-N-acetylglucosamine (O-GlcNAc) hydrolase and cryptic lysine acetyltransferase activities. Here, we report that OGA is upregulated in a wide range of human cancers and drives aerobic glycolysis and tumor growth by inhibiting pyruvate kinase M2 (PKM2). PKM2 is dynamically O-GlcNAcylated in response to changes in glucose availability. Under high glucose conditions, PKM2 is a target of OGA-associated acetyltransferase activity, which facilitates O-GlcNAcylation of PKM2 by O-GlcNAc transferase (OGT). O-GlcNAcylation inhibits PKM2 catalytic activity and thereby promotes aerobic glycolysis and tumor growth. These studies define a causative role for OGA in tumor progression and reveal PKM2 O-GlcNAcylation as a metabolic rheostat that mediates exquisite control of aerobic glycolysis.

Abstract
OBJECTIVE Perlecan, which is also called heparan sulfate proteoglycan 2 (HSPG2), is a protein encoded by the HSPG2 gene that maps to 1p36.12 in the human genome. In this study, we assessed the independent prognostic value of HSPG2 in terms of overall survival (OS) and recurrence-free survival (RFS) in patients with LGG. PATIENTS AND METHODS A retrospective study was conducted by using data in the Cancer Genome Atlas-Low Grade Glioma (TCGA-LGG). RESULTS Increased HSPG2 expression was an independent prognostic indicator of poor OS in oligoastrocytoma (HR: 1.644, 95% CI: 1.116-2.423, p = 0.012) and in oligodendroglioma (HR: 1.459, 95% CI: 1.138-1.871, p = 0.003). In addition, increased HSPG2 expression independently predicted poor RFS in oligodendroglioma (HR: 1.402, 95% CI: 1.110-1.770, p = 0.005). Furthermore, we observed that high HSPG2 expression was associated with significantly shorter OS and RFS in oligodendroglioma, no matter the patients received radiotherapy or not. Using copy number alterations (CNAs) and DNA methylation data in TCGA-LGG, we found that DNA copy deletion was generally associated with decreased HSPG2 expression. Regression analysis suggested a weak negative correlation between HSPG2 expression and HSPG2 DNA methylation (Pearson's r = -0.388). CONCLUSIONS Increased HSPG2 expression could independently predict poor OS in oligoastrocytoma and oligodendroglioma and also independently predicted poor RFS in oligodendroglioma. Its expression is modulated by both DNA copy number and DNA methylation in oligodendroglioma.

Abstract
Objective: To explore the efficacy of tenofovir disoproxil and adefovir dipivoxil treatment in patients with hepatitis B virus e antigen (HBeAg) negative was analyzed through the comparison of highly sensitive HBV viral load monitoring with HBV genotyping and drug resistance mutations. Methods: The clinical data of newly diagnosed chronic hepatitis B patients from January 2015 to June 2017 in outpatients and inpatients were randomly divided into tenofovir and adefovir group. Quantitative detection of HBV DNA levels before therapy and at 12, 24, 48, 96, and 120 weeks after therapy were determined for HBV genotypes and drug-resistant mutations in HBeAg-negative patients. Student's t-test was used to compare the measurement data between groups. The data of comparison between groups were tested by χ (2). Results: A total of 106 cases of HBeAg-negative patients were collected. Tenofovir disoproxil had a higher rate of HBV DNA suppression (54%) than adefovir dipivoxil treatment (42%), but the difference was not statistically significant (P = 0.19). After 120 weeks of treatment, a total of 46 patients (93.9%) were enrolled in the tenofovir disoproxil group with HBV DNA quantitation < 2 000 IU / ml. Adefovir dipivoxil group of patients with HBV DNA < 2 000 IU / ml a total of 40 cases, accounting for 75.5%. The difference between the two groups was statistically significant (P < 0.05). For 49 cases of HBeAg-negative patients, HBV B, C, B and C were mixed before tenofovir dipivoxil treatment, and C1653T, A1762T and G1764A mutation sites were detected in patients with D genotype. Patients C, B, C, B, and C were examined for C1673T, G1896, G1858, G1899A. After treatment, the detection rate of the above mutation sites decreased, but C1653T, C1673T and G1899A were not detected. New mutation sites such as G1915A / C, L180M, M204V, V207I / L, T184A and V173L were detected, Low resistance rate (25%). Conclusion: Tenofovir disoproxil can be recommended as a treatment for HBeAg-negative patients. For HBeAg-negative patients, the choice of high-sensitivity detection of HBV DNA levels, better monitoring of anti-HBV efficacy.

Abstract
An increasing number of unruptured intracranial aneurysms (UIAs) has been
discovered in elderly patients in recent years, but the optimal treatment
strategy for these patients remains controversial. We report our six-year
experience treating UIAs in elderly patients (≥ 70 years old). A retrospective
review was conducted of elderly patients who harbored UIAs treated by
conservative observation, microsurgical clipping, or endovascular coiling
between January 2009 and December 2014. The patients’ clinical and imaging
information was recorded. Treating methods, procedure-related complications,
imaging results, and clinical outcomes were analyzed. A total of 141 consecutive
elderly patients with 166 UIAs were enrolled in our study. In all, 64 patients
with 79 aneurysms were treated with coiling, and 14 patients with 14 aneurysms
were treated with clipping. The remaining 63 patients with 73 aneurysms were
placed under conservative observation. The average modified Rankin scale was
0.99 (range 0–6) in the full cohort after a mean follow-up of 50.4 months (range
0–70 months). There was no significant difference of modified Rankin scale in
patients with UIAs treated by different methods. Multivariate analysis showed
that age (p=0.030) and aneurysm size (p=0.011)
were independent risk factors for unfavorable outcome of UIAs in the elderly.
Patient age (p=0.010) and aneurysm size
(p=0.020) were also significantly associated with unfavorable
outcome of UIAs managed with observation initially. Our results indicated that
endovascular coil embolization and clipping were both safe and effective
treatment methods for UIAs in the elderly. Aggressive treatment for UIAs in
elderly patients with risk factors of aneurysm rupture should be considered
positively.

Abstract
Objective: To analyze the composition and richness of intestinal microflora in children with non-alcoholic fatty liver disease (NAFLD) and the role of which in pathogenesis of NAFLD. Methods: This was a prospective case-control study. From November 2015 to June 2017, 19 children diagnosed with NAFLD according to the 2010 edition of diagnostic criteria were enrolled voluntarily in the Second and First Affiliated Hospitals of Zhejiang Chinese Medicine University. Twenty-two healthy children were enrolled in the control group. Among the patients, 10 were males and 9 were females, at the mean age of (11.0±1.0) years; 10 males and 12 females in the control group, at the mean age of (9.0±1.2) years. The body mass index (BMI) and waist circumference were recorded, and the fasting blood glucose, total cholesterol, triglyceride, high-density lipoprotein and low-density lipoprotein were detected. Feces were collected and the fecal microorganisms were extracted with magnetic beads methods; the composition and the richness of intestinal microflora in the two groups were detected with 16S rDNA high throughput sequencing technology. The KO differential gene expression and KEGG signal pathway enrichment were analyzed with PICRUST software. The intestinal flora characteristics between the two groups were compared with t test or Mann-Whitney U test and Willcoxon W test. Results: The BMI, waist circumference and triglyceride were higher in NAFLD group than those in the control group (BMI (25.1±2.7) vs. (18.2±1.5)kg/m(2), t=9.912, P=0.000; waist circumference (88.6±6.6) vs. (71.5±6.3) cm, t=8.520, P=0.000; triglyceride (0.9±0.4) vs.(0.7±0.3)mmol/L, t=2.060, P=0.046). The abundance and diversity index of intestinal microflora were lower in the NAFLD group (Shannon index 3.99 (3.13, 4.54) vs. 4.63 (4.21, 4.81), Z=-2.065, P=0.039; Simpson index 0.85 (0.70, 0.89) vs. 0.90 (0.88, 0.93), Z=-2.431, P=0.015; ACE index 235.76 (205.26, 361.94) vs. 326.96 (275.34, 368.65), Z=-2.092, P=0.036). At the level of phylum, the proportion of Actinomycetes was lower and the proportion of Thermus was higher in NAFLD group (Actinobacteri 29.807 (14.723, 62.080) ×10(-3) vs. 63.212 (46.133, 172.071) ×10(-3), Z=-2.667, P=0.008; Thermus 0.033 (0.000, 0.226) ×10(-3) vs. 0.000 (0.000, 0.031) ×10(-3), Z=-2.729, P=0.006) . At the level of genus, the proportion of Bacteroides and Bifidobacterium in the NAFLD group were significantly lower (Bacteroides 78.757 (11.430, 151.621) ×10(-3) vs. 356.821 (161.049, 403.037) ×10(-3), Z=-2.771, P=0.006; Bifidobacterium 19.680 (6.181, 53.944) ×10(-3) vs. 54.721 (31.911, 146.410) ×10(-3), Z=-2.458, P=0.014); the proportion of Prevotella in NAFLD group was significantly higher (3.089 (0.165, 63.502) ×10(-3) vs. 0.432 (0.029, 2.257) ×10(-3), Z=-2.112, P=0.035). Based on the KEGG database, 78 differentially expressed genes and 26 differential metabolic pathways were found, among which the function genes of K01470, K01961 and K07258 were concentrated in the pathways of arginine and proline metabolism, fatty acid synthesis, and polysaccharides biosynthesis and metabolism. Besides, these three function genes were related to Bacteroides, Prevotella, Bifidobacterium and Ruminococcus. Conclusion: NAFLD children have intestinal flora disturbances in both diversity and abundance, which may alter lipid metabolic pathways through differential gene expressions, contributing to the pathogenesis of NAFLD.

Abstract
Juvenile amyotrophic lateral sclerosis (JALS) occurs at an age of onset below 25 years with a heterogeneous disease onset location, variable progression and survival time. To investigate whether an ALS gene profile could resolve any aspects of clinical symptom heterogeneity, we have used targeted sequencing technology in a cohort of 12 JALS patients of Chinese descent. We detected 5 likely pathogenic mutations, 2 in familial probands and 3 in sporadic patients. One was a known TARDBP mutation (p.G348V) and 4 were FUS frameshift mutations including a known p.Gln519Ilefs*9 mutation and 3 novel mutations, p.Gly515Valfs*14, p.Gly486Profs*30, and p.Arg498Alafs*32. Of the 4 FUS mutations, 2 were able to be confirmed as de novo mutations. The TARDBP mutation carrier showed a classic ALS phenotype. All patients with FUS mutations experienced limb weakness at an early age and developed bulbar symptoms during the disease course. FUS mutations have previously been associated with increased JALS disease progression, however, we found a large range 12 to 84 months in disease survival (mean 58.2 months). Our results justify future screening for variants in FUS as it remains the most frequent genetic determinant of early onset, JALS (found in 30% of our patients).

Abstract
UNLABELLED This study used a simulation model to determine the cost-effective threshold of fracture risk to treat osteoporosis among elderly Chinese women. Osteoporosis treatment is cost-effective among average-risk women who are at least 75 years old and above-average-risk women who are younger than 75 years old. INTRODUCTION Aging of the Chinese population is imposing increasing economic burden of osteoporosis. This study evaluated the cost-effectiveness of osteoporosis treatment among the senior Chinese women population. METHODS A discrete event simulation model using age-specific probabilities of hip fracture, clinical vertebral fracture, wrist fracture, humerus fracture, and other fracture; costs (2015 US dollars); and quality-adjusted life years (QALYs) was used to assess the cost-effectiveness of osteoporosis treatment. Incremental cost-effectiveness ratio (ICER) was calculated. The willingness to pay (WTP) for a QALY in China was compared with the calculated ICER to decide the cost-effectiveness. To determine the absolute 10-year hip fracture probability at which the osteoporosis treatment became cost-effective, average age-specific probabilities for all fractures were multiplied by a relative risk (RR) that was systematically varied from 0 to 10 until the WTP threshold was observed for treatment relative to no intervention. Sensitivity analyses were also performed to evaluate the impacts from WTP and annual treatment costs. RESULTS In baseline analysis, simulated ICERs were higher than the WTP threshold among Chinese women younger than 75, but much lower than the WTP among the older population. Sensitivity analyses indicated that cost-effectiveness could vary due to a higher WTP threshold or a lower annual treatment cost. A 30 % increase in WTP or a 30 % reduction in annual treatment costs will make osteoporosis treatment cost-effective for Chinese women population from 55 to 85. CONCLUSIONS The current study provides evidence that osteoporosis treatment is cost-effective among a subpopulation of Chinese senior women. The results also indicate that the cost-effectiveness of using osteoporosis treatment is sensitive to the WTP threshold and annual treatment costs.

Abstract
OBJECTIVE To observe the expression of neural axon guidance molecules Slit3 and Robo receptors in mouse aortic smooth muscle cell(MASMC) and investigate the effect of exogenous Slit3 protein on migration and proliferation of MASMC. METHODS The primary cultured MASMC were identified by immunofluorescent assay. The expression of Slit3/Robo signal pathway was detected by RT-PCR and immunocytochemical staining. MASMC were divided into 6 groups: the negative control group (DMEM medium containing bovine serum albumin 86 μg/L), Slit3 0 μg/L group (DMEM medium without Slit3), Slit3 24 μg/L group (DMEM medium containing Slit3 24 μg/L), Slit3 40 μg/L group (DMEM medium containing Slit3 40 μg/L), Slit3 80 μg/L group (DMEM medium containing Slit3 80 μg/L) and the positive control group (DMEM medium containing platelet derived growth factor 10 μg/L). The effects of exogenous Slit3 on MASMC proliferation and migration were detected by CCK-8 and scratched cells and transwell chambers respectively. RESULTS (1) The mRNA and protein expressions of Slit2, Slit3, Robo1 and Robo4 were detected in MASMC. mRNA level of Slit2 was lower than Slit3 (P<0.05) and there were no significant difference between mRNA level of Robo1 and Robo4. (2) The mitogenic responses of MASMC were significantly enhanced in Slit3 24 μg/L group, Slit3 40 μg/L group and Slit3 80 μg/L group compared with negative control group (1.13±0.04, 1.19±0.02, 1.18±0.08 and 0.64±0.10 respectively, all P<0.05). The mitogenic activity of MASMC was the strongest in Slit3 40 μg/L group (compared with positive control group 1.27±0.05, P>0.05). (3)The autonomous migration activity of MASMC were significantly increased in Slit3 24 μg/L group, Slit3 40 μg/L group, Slit3 80 μg/L group compared with negative control group (cell scratch width were (0.40±0.03)cm, (0.32±0.03)cm, (0.30±0.02)cm and (0.49±0.01)cm respectively, all P<0.05). The autonomous migration activity of MASMC was the strongest in Slit3 80 μg/L group (compared with positive control group (0.22±0.01)cm, P>0.05). The transmembrane migration activity of MASMC were significantly increased in Slit3 24 μg/L group, Slit3 40 μg/L group, Slit3 80 μg/L group compared with negative control group (the number of cell migration were 46.67±2.23, 65.33±3.43, 81.67±4.22 and 39.33±2.03 respectively, all P<0.05). The transmembrane migration activity of MASMC was the strongest in Slit3 80 μg/L group (compared with positive control group 84.00±2.02, P>0.05). CONCLUSION Slit2, Slit3, Robo1 and Robo4 were expressed in MASMC, and exogenous Slit3 could promote proliferation and migration of MASMC in vitro.
