Abstract
The objective was to evaluate the efficacy of curcumin in improving mouth opening (MO), burning sensation (BS), and tongue protrusion (TP) symptoms in patients with oral submucous fibrosis (OSF). An electronic search up to November 2022 was conducted in the PubMed, Web of Science, Embase, EBSCO, ProQuest, and Cochrane Library databases to identify studies using curcumin in the treatment of OSF with comparison to control groups (drugs previously proven to be effective for OSF treatment) or placebo. Only randomized controlled trials (RCTs) were considered. RevMan 5.3 software was used for the meta-analysis. Thirteen RCTs met the eligibility criteria and were included in the analysis. The results showed no significant improvement in MO (in millimetres) for curcumin when compared to control at 1 month (P = 0.91), 2 months (P = 0.54), 3 months (P = 0.56), or 6 months (P = 0.17) of treatment. There was no significant difference in BS (assessed using a visual analogue scale) between curcumin and control after 1 month (P = 0.05), 2 months (P = 0.64), 3 months (P = 0.13), or 6 months (P = 0.56) of treatment. Compared with the control groups, treatment with curcumin for 1 month (P = 0.32), 2 months (P = 0.07), and 3 months (P = 0.14) did not significantly improve the TP (in millimetres) of patients. The administration of curcumin, whether topically applied or taken orally, did not confer statistically significant improvements in MO, BS, or TP in comparison to the control treatments, among patients with OSF. The results of this meta-analysis showed that compared to placebo, the application of curcumin for 6 months markedly alleviated BS (P < 0.001). Curcumin treatment in OSF reaches a clinically effective range, but more bioavailability-centred outcomes should be reported. Robust multicentre RCTs are warranted to elucidate the efficacy of curcumin in improving specific outcomes like MO, BS, and TP in patients with this condition. Defining the therapeutic role of this natural compound may provide an effective botanical alternative for managing OSF.

Abstract
The medicinal plant Sophora tonkinensis is a characteristic Chinese shrub of karst areas. The arid climate in karst areas produces high-quality S. tonkinensis; however, the mechanisms of drought tolerance are not clear, which restricts sustainable plantings of S. tonkinensis. This study involved a 20-day drought stress experiment with potted S. tonkinensis and threee soil water regimes: control (CK), mild drought (MDT), and severe drought (SDT). Plant morphology, biomass, physiological indicators, alkaloid content, and other changes under drought stress were monitored. The content of soluble sugars and proteins, and activity of antioxidant enzymes in leaves and roots were higher under drought than CK, indicating that S. tonkinensis is tolerant to osmotic stress in early drought stages. Content of matrine and oxymatrine increased gradually with increasing drought duration in the short term. The epidermis of S. tonkinensis leaves have characteristics of desert plants, including upper epidermal waxy layer, lower epidermal villi, and relatively sunken stomata, suggesting that S. tonkinensis has strong drought tolerance. In conclusion, drought stress changed the cell structure of S. tonkinensis, induced antioxidant enzyme activity and increased its resistance to drought.

Abstract
OBJECTIVES China may face new threats to public health due to the increased risk of imported mpox (monkeypox) cases. However, research gaps exist in the acceptance of mpox vaccination and potential associated factors in the Chinese population. STUDY DESIGN We conducted a cross-sectional study targeting community residents in Shenzhen, China, from August 5 to September 7 2022. METHODS A self-administered questionnaire was used to collect information about demographic and health characteristics, mpox-related perceptions, and attitudes towards mpox vaccination. Multivariable logistic regression models were applied to detect the factors associated with willingness to receive and recommend mpox vaccination. RESULTS A total of 2293 community residents were included in the analyses (average age: 34.03, female: 72.6%). Among the participants, 76.9% were aware of mpox, 62.1% were aware of the global mpox outbreak, but only 53.6% had a high knowledge level of mpox. Males had a higher proportion of high knowledge (56.9% vs 52.3%, P<0.05) and a lower proportion of high worry (30.2% vs 45.4%, P<0.05) than females. Approximately 69.1% of the participants were willing to vaccinate against mpox, and 69.6% were willing to recommend mpox vaccination to people around them, in which no gender difference was found. The obstacle reported most among people hesitant to receive vaccination was concerning the safety and side-effects, whereas it changed to be concerning the suitability due to individual health differences among people hesitant to recommend mpox vaccines. Factors associated with the willingness to receive and recommend mpox vaccination included having a history of influenza vaccination, having a history of COVID-19 vaccination, being aware of the global mpox outbreak, having a high knowledge level of mpox, and having a high level of mpox-related worry. CONCLUSIONS This study identified a moderate willingness to receive and recommend mpox vaccination among Chinese adults. Without gender differences, willingness to receive and recommend mpox vaccination was significantly associated with mpox-related perceptions, such as awareness, knowledge, and worry. Authoritative and up-to-date information is needed to help the general population improve public confidence in mpox vaccines in China.

Abstract
PURPOSE/OBJECTIVE(S) Re-radiotherapy (re-RT) is the main treatment for locally recurrent nasopharyngeal carcinoma (lrNPC) patients, and commonly led to radiation-induced nasopharyngeal (NP) necrosis, which was lethal but rare study has focused on it. The aim of this study was to evaluate the cause and impact of radiation-induced NP necrosis in lrNPC patients who received re-RT. MATERIALS/METHODS Totally 252 lrNPC patients who received re-RT between January 2013 and December 2020 were retrospectively collected. The inclusion criteria were as follows: (1) no NP necrosis before re-RT; (2) complete medical records, including treatment, clinical and dosimetric information; (3) conventional fractionated radiotherapy. All patients received intensity-modulated radiotherapy ± chemotherapy. Radiation-induced NP necrosis was diagnosed by magnetic resonance imaging and/or electronic nasopharyngoscopy. Dosimetric factors of the planning target volume of primary tumor (PTVp) were extracted from the dose-volume histogram (DVH), which was rescaled to an equivalent dose of 2 Gy per fraction (EQD 2 Gy) using a linear quadratic model. Logistic regression was used to identify the independent prognostic factors for generating the nomogram. RESULTS With a median follow-up of 44.63 months (inter-quartile range [IQR], 27.70 - 69.20 months), 47.6% of patients (120/252) occurred radiation-induced NP necrosis, which mostly happened within 1 year post re-RT (median [IQR], 5.83 [3.37 - 11.57] months). The 3-year overall survival was 83.0% vs 39.7% (P<0.001) in lrNPC patients with or without radiation-induced NP necrosis. Except for the fractionated dose, other dosimetric factors of PTVp were not significantly different between two groups, including D98 (dose to 98% of PTVp), D50, D2 and homogeneity index (Table 1). Furthermore, multivariate analysis showed that continuous variable age (HR [95% CI]: 1.04 [1.02 - 1.07], P = 0.003) and tumor volume (HR [95% CI]: 1.02 [1.01 - 1.03], P<0.001), and fractionated dose > 2.22 Gy (HR [95% CI]: 2.36 [1.32 - 4.21], P = 0.004) were independent factors in predicting radiation-induced NP necrosis, which yielded a C-index of 0.742 (95% CI, 0.682 - 0.803) for OS in the nomogram. CONCLUSION The incidence of radiation-induced NP necrosis was high in lrNPC patients who received re-RT. Patients with older age, larger tumor volume or receiving fractionated dose over 2.22 Gy were more easily to suffer NP necrosis, which need to explore novel treatment strategies to improve patients' survivals.

Abstract
BACKGROUND AND PURPOSE Endovascular treatment is a reference treatment for acute basilar artery occlusion (ABAO). However, no established and specific methods are available for the preoperative screening of patients with ABAO suitable for endovascular treatment. This study explores the potential value of DWI-based radiomics in predicting the functional outcomes of endovascular treatment in ABAO. MATERIALS AND METHODS Patients with ABAO treated with endovascular treatment from the BASILAR registry (91 patients in the training cohort) and the hospitals in the Northwest of China (31 patients for the external testing cohort) were included in this study. The Mann-Whitney U test, random forests algorithm, and least absolute shrinkage and selection operator were used to reduce the feature dimension. A machine learning model was developed on the basis of the training cohort to predict the prognosis of endovascular treatment. The performance of the model was evaluated on the independent external testing cohort. RESULTS A subset of radiomics features (n = 6) was used to predict the functional outcomes in patients with ABAO. The areas under the receiver operating characteristic curve of the radiomics model were 0.870 and 0.781 in the training cohort and testing cohort, respectively. The accuracy of the radiomics model was 77.4%, with a sensitivity of 78.9%, specificity of 75%, positive predictive value of 83.3%, and negative predictive value of 69.2% in the testing cohort. CONCLUSIONS DWI-based radiomics can predict the prognosis of endovascular treatment in patients with ABAO, hence allowing a potentially better selection of patients who are most likely to benefit from this treatment.

Abstract
OBJECTIVE Intervertebral disc degeneration (IDD) has been reported to be a major cause of low back pain (LBP). Interleukin (IL)-37 is an anti-inflammatory cytokine of the interleukin-1 family, which exerts salutary physiological effects. In this study, we assessed the protective effect of IL-37 on IDD progression and its underlying mechanisms. METHODS Immunofluorescence (IF) was conducted to measure IL-37 expression in nucleus pulposus tissues. CCK-8 assay and Edu staining were used to examine the vitality of IL-37-treated nucleus pulposus cells (NPCs). Western blot, qPCR, ELISA as well as immunohistochemistry were used to assess senescence associated secreted phenotype (SASP) factors expression; and NF-κB pathway was evaluated by western blot and IF; while IL-1R8 knock-down by siRNAs was performed to ascertain its significance in the senescence phenotype modulated by IL-37. The therapeutic effect of IL-37 on IDD were evaluated in puncture-induced rat model using X-ray, Hematoxylin-Eosin, Safranin O-Fast Green (SO), and alcian blue staining. RESULTS We found IL-37 expression decreased in the IDD process. In vitro, IL-37 suppressed SASP factors level and senescence phenotype in IL-1β treated NPCs. In vivo, IL-37 alleviated the IDD progression in the puncture-induced rat model. Mechanistic studies demonstrated that IL-37 inhibited IDD progression by downregulating NF-κB pathway activation in NPCs by activating IL-1R8. CONCLUSION The present study suggests that IL-37 delays the IDD development through the IL-1R8/NF-κB pathway, which suggests IL-37 as a promising novel target for IDD therapy.

Abstract
Drought stress (DS) is a serious abiotic stress and a major concern across the globe as its intensity is continuously climbing. Therefore, it is direly needed to develop new management strategies to mitigate the adverse effects of DS to ensure better crop productivity and food security. The use of arbuscular mycorrhizal fungi (AMF) has emerged as an important approach in recent years to improve crop productivity under DS conditions. AMF establishes a relationship with 80% of land plants and it induces pronounced impacts on plant growth and provides protection to plants from abiotic stress. Drought stress significantly reduces plant growth and development by inducing oxidative stress, disturbing membrane integrity, plant water relations, nutrient uptake, photosynthetic activity, photosynthetic apparatus, and anti-oxidant activities. However, AMF can significantly improve the plant tolerance against DS. AMF maintains membrane integrity, improves plant water contents, nutrient and water uptake, and water use efficiency (WUE) therefore, improve the plant growth under DS. Moreover, AMF also protects the photosynthetic apparatus from drought-induced oxidative stress and improves photosynthetic efficiency, osmolytes, phenols and hormone accumulation, and reduces the accumulation of reactive oxygen species (ROS) by increasing anti-oxidant activities and gene expression which provide the tolerance to plants against DS. Therefore, it is imperative to understand the role of AMF in plants grown under DS. This review presented the different functions of AMF in different responses of plants under DS. We have provided a detailed picture of the different mechanisms mediated by AMF to induce drought tolerance in plants. Moreover, we also identified the potential research gaps that must be fulfilled for a promising future for AMF. Lastly, nitrogen (N) is an important nutrient needed for plant growth and development, however, the efficiency of applied N fertilizers is quite low. Therefore, we also present the information on how AMF improves N uptake and nitrogen use efficiency (NUE) in plants.

Abstract
Background Colonization has been reported to play an important role in carbapenem-resistant Enterobacterales (CRE) infection; however, the extent to which carriers develop clinical CRE infection and related risk factors in neonatal intensive care unit (NICU) patients is unclear. Aim To investigate the frequency of CRE colonization and its contribution to infections in NICU patients. Methods CRE colonization screening and CRE infection surveillance were performed in the NICU in 2017 and 2018. Findings Among 1230 unique NICU patients who were screened for CRE colonization, 144 patients tested positive (11.7%, 144/1230), with 9.2% (110/1197) in the intestinal tract, which was higher than that in the upper respiratory tract (6.6%, 62/945) (P=0.026). Gestational age, low birth weight and prolonged hospitalization were risk factors for CRE colonization (all P<0.001). Diversilab homology monitoring found an overall 17.4% (25/144) risk of infection among patients colonized with CRE. For carbapenem-resistant Klebsiella pneumoniae (CR-KP) and carbapenem-resistant Escherichia coli (CR-ECO), the risks were 19.1% (21/110) and 13.8% (4/29), respectively. The independent risk factors for CR-KP clinical infection among CR-KP carriers were receiving mechanical ventilation (odds ratio (OR), 10.177; 95% confidence interval (CI), 2.667–38.830; P=0.013), a high level of neonatal nutritional risk assessment (OR, 0.251; 95% CI, 0.072–0.881; P=0.031) and a high neonatal acute physiology II (SNAP-II) score (OR, 0.256; 95% CI, 0.882–1.034; P=0.025). Conclusions The colonization of CRE may increase the incidence of corresponding CRE infection in NICU patients. Receiving mechanical ventilation, malnutrition and critical conditions with high SNAP-II scores were independent risk factors for subsequent CR-KP clinical infection.

Abstract
BACKGROUND Nucleotide-binding oligomerization domain-like receptor family, pyrin domain containing 3 (NLRP3)-associated autoinflammatory disease (NLRP3-AID) is a rare, heterogeneous disease entity associated with mutations in NLRP3. Biologic therapy for NLRP3-AID yields diverse results. OBJECTIVES We aimed to evaluate the clinical features and outcomes of Chinese adult patients with NLRP3-AID who were treated with tumour necrosis factor (TNF)-α inhibitors. METHODS Five patients with NLRP3-AID were diagnosed and treated with TNF-α inhibitors at Peking Union Medical College Hospital between 2017 and 2020 and were followed up for 6 to 12 months. All patients were systematically studied for treatment outcomes, including clinical manifestations and inflammatory markers. RESULTS All five adult NLRP3-AID patients were Chinese Han, and four patients were males. The mean age at disease onset was 4.2 ± 4.1 years, and the mean time of diagnosis delay was 19.8 ± 6 years. All patients received TNF-α inhibitors with or without methotrexate/prednisone. During follow-up, all patients achieved remarkable clinical remission of skin lesions and polyarthritis and showed improvements in acute-phase reactants, inflammatory cytokines, patient visual analogue scale, physician global assessment and 36-item Short Form (SF-36). CONCLUSIONS Early diagnosis and effective therapy for NLRP3-AID are essential for avoiding irreversible organ damage. TNF-α inhibitors might serve as a therapeutic alternative for patients with NLRP3-AID who have unsatisfactory responses or no access to interleukin-1 inhibitors.

Abstract
Objective: To observe the clinical effect of integrated traditional Chinese and western medicine on brucellosis and its influence on humoral immune indexes. Methods: In October 2019, 169 cases of brucellosis hospitalized in Tianjin Second People's Hospital were selected as the research objects, and divided into two groups according to the random number method, 84 cases in the integrated treatment group and 85 cases in the western medicine treatment group. The western medicine treatment group was given antibiotics and other routine western medicine support treatment. The integrated treatment group was given traditional Chinese medicine for treatment based on syndrome differentiation, on the basis of western medicine treatment group, and 6 weeks was a course of treatment. The clinical efficacy and Traditional Chinese Medicine (TCM) syndrome scores were compared between the two groups of patients after treatment, and the changes in humoral immune indexes, biochemical, and liver and kidney functions of the patients before and after treatment were analyzed. Results: The total effective rate was 100.00% (84/84) in the integrated treatment group and 97.65% (83/85) in the western medicine treatment group. The difference was not statistically significant (P>0.05) . The difference was not statistically significant (P>0.05) . There was no statistically significant difference in TCM syndrome scores between the two groups before treatment (P>0.05) , and the TCM syndrome scores after treatment were lower than before treatment (P<0.05) . Among them, the TCM syndrome scores of the integrated treatment group were lower than those of the western medicine treatment group (P<0.05) . There was no significant difference in IgG, IgA, IgM, C3, C4, miRNA-155, C-reactive protein (CRP) , erythrocyte sedimention rate (ESR) , alanine aminotransferase (ALT) and aspartate aminotransferase (AST) between the two groups before treatment (P>0.05) . After treatment, IgG, IgA, IgM, miRNA-155, CRP, ESR, ALT and AST were all lower than before treatment, and C3 and C4 complement levels were higher than before treatment (P<0.05) . Among them, IgG, IgA, IgM, miRNA-155, CRP, ESR, ALT and AST in the integrative treatment group were all lower than the western medicine treatment group, while the C3 and C4 complement levels were higher than the western medicine treatment group (P<0.05) . Conclusion: The treatment of brucellosis with integrated traditional Chinese and western medicine can significantly improve the TCM syndrome score and reduce the levels of CRP and ESR. The mechanism of action may be related to the regulation of the patient's humoral immunological indicators.

Abstract
Using first-principles transport calculations, we predict that the anisotropic magnetoresistance (AMR) of single-crystal Co_{x}Fe_{1-x} alloys is strongly dependent on the current orientation and alloy concentration. An intrinsic mechanism for AMR is found to arise from the band crossing due to magnetization-dependent symmetry protection. These special k points can be shifted towards or away from the Fermi energy by varying the alloy composition and hence the exchange splitting, thus allowing AMR tunability. The prediction is confirmed by delicate transport measurements, which further reveal a reciprocal relationship of the longitudinal and transverse resistivities along different crystal axes.

Abstract
OBJECTIVE To investigate the function of miRNA-21 and interleukin-6 receptor/Janus Kinase-Signal transducer and activator of transcription (IL-6R/JAK-STAT) pathway in microglia on inflammatory responses after spinal cord injury (SCI). MATERIALS AND METHODS This study first detected respectively the protein level of inflammatory factor inducible nitric oxide synthase (iNOS) and tumor necrosis factor alpha (TNF-α) by Western blotting after transfection of miR-21 or administration of miR-21 inhibitor in activated microglia cells of rat in vitro. The quantitative Real-time polymerase chain reaction (qRT-PCR) was utilized to detect the expression of IL-6R under two different interventions. Next, we established a model of spinal cord injury in rat and inspected miR-21 and IL-6R in SCI rat by qRT-PCR. In addition, the protein levels of iNOS and TNF-α in SCI rat were detected by Western blotting. MiR-21 inhibitor was injected into the injured area of SCI rat to delve into the function of miR-21 down-expression on iNOS and TNF-α expression by Western blot as well as the RNA levels of IL-6R, JAK and STAT3 by qRT-PCR. Furthermore, the SCI rat with movement and coordination of hindlimbs was observed by Basso-Beattie-Bresnahan locomotor rating scale (BBB scale) after miR-21 down-expression. RESULTS Compared with the microglia transfected with miR-21, the execution of inhibitor in microglia effectively relieved the expression of IL-6R and the breakout of iNOS and TNF-α. Meanwhile, the increase of miR-21 was significantly observed in SCI rat along with significant improvement of inflammatory response-related factors including iNOS and TNF-α. After that, we injected SCI rat with miR-21 inhibitor into the spinal cord injury area and found the inhibition of miR-21 decreased the protein levels of iNOS and TNF-α. Simultaneously, down-expression of miR-21 evidently declined the RNA levels of IL-6R, JAK, and STAT3 in SCI rat. Compared with the sham-operated rat, the movement and coordination of hindlimbs of the SCI group displayed dramatic dysfunction. However, miR-21 down-expression elevated the movement and coordination of hindlimbs of the SCI rat than those of the only injury group. CONCLUSIONS Inhibition of miR-21 can promote the recovery of spinal cord injury by down-regulating IL-6R/JAK-STAT signaling pathway and inhibiting inflammation.

Abstract
Deep brain stimulation (DBS) for Parkinson's disease (PD) is an established advanced therapy that produces therapeutic effects through high frequency stimulation. Although this therapeutic option leads to improved clinical outcomes, the mechanisms of the underlying efficacy of this treatment are not well understood. Therefore, investigation of DBS and its postoperative effects on brain architecture is of great interest. Diffusion weighted imaging (DWI) is an advanced imaging technique, which has the ability to estimate the structure of white matter fibers; however, clinical application of DWI after DBS implantation is challenging due to the strong susceptibility artifacts caused by implanted devices. This study aims to evaluate the feasibility of generating meaningful white matter reconstructions after DBS implantation; and to subsequently quantify the degree to which these tracts are affected by post-operative device-related artifacts. DWI was safely performed before and after implanting electrodes for DBS in 9 PD patients. Differences within each subject between pre- and post-implantation FA, MD, and RD values for 123 regions of interest (ROIs) were calculated. While differences were noted globally, they were larger in regions directly affected by the artifact. White matter tracts were generated from each ROI with probabilistic tractography, revealing significant differences in the reconstruction of several white matter structures after DBS. Tracts pertinent to PD, such as regions of the substantia nigra and nigrostriatal tracts, were largely unaffected. The aim of this study was to demonstrate the feasibility and clinical applicability of acquiring and processing DWI post-operatively in PD patients after DBS implantation. The presence of global differences provides an impetus for acquiring DWI shortly after implantation to establish a new baseline against which longitudinal changes in brain connectivity in DBS patients can be compared. Understanding that post-operative fiber tracking in patients is feasible on a clinically-relevant scale has significant implications for increasing our current understanding of the pathophysiology of movement disorders, and may provide insights into better defining the pathophysiology and therapeutic effects of DBS.

Abstract
A mode splitter is a key device to eliminate undesired modes but allow desired modes go through for an on-chip mode-division multiplexing (MDM) system. Here, we propose a silicon high-order mode (HOM) pass filter based on the cascaded plasmonic bridged subwavelength gratings (BSWGs). A metal bridge is introduced to generate a plasmonic hybrid mode, which has a significant influence on the fundamental mode but a neglected impact on the first-order mode. A silicon HOM-pass filter for handling the TM0 and TM1 modes is optimized by using the 3D full-vectorial finite difference time domain (3D-FV-FDTD) method. The numerically simulated results indicate that the optimized mode filter is with a low loss of 0.63 dB and a mode extinction ratio (ER) of 26.4 dB based on 4-cascaded plasmonic BSWGs. The 3 dB bandwidth is over 493 nm from 1222 nm to 1715 nm. With the mode ER > 15.0 dB, a broad bandwidth of 150 nm can be achieved. The performance of the proposed mode filter is tolerant to the width error of ± 50 nm. The proposed silicon HOM-pass filter can be utilized in on-chip MDM systems for mode controlling.

Abstract
Abstract
Background
With the advent of multiple novel therapeutics for light chain (AL) and transthyretin (ATTR) amyloidosis, there is a critical need for validated prognostic markers in cardiac amyloidosis. A discriminatory serum biomarker may improve prognostic and staging systems in AL and ATTR cardiac amyloidosis.
Purpose
Our objective was to test the hypothesis that hepatocyte growth factor (HGF) is associated with clinical outcomes in patients with AL and ATTR cardiac amyloidosis.
Methods
102 patients with AL or ATTR and suspected cardiac involvement were prospectively enrolled. HGF, NT-proBNP, troponin-T, and eGFR were measured upon study enrollment. Cardiac involvement was established by 1) endomyocardial biopsy, or 2) non-cardiac biopsy with concentric hypertrophy on echocardiography, low voltage or pseudo-infarction on ECG, elevated NT-proBNP or troponin-T, or characteristic delayed myocardial enhancement on cardiac MRI. Patients were followed for the occurrence of all-cause mortality, cardiac transplantation, and left-ventricular assist device implantation.
Results
Of the total amyloidosis cohort, 72 had cardiac involvement while 30 had non-cardiac disease. HGF, NT-proBNP, and troponin-T levels were significantly higher in patients with cardiac involvement than in patients with non-cardiac disease (p<0.05 for all comparisons). Over a median follow-up period of 1.9 years there were 20 deaths, 1 cardiac transplant, and 1 left-ventricular assist device implant, all in patients with cardiac involvement. Patient stratification by cut-off levels of NT-proBNP (332 pg/mL), troponin-T (35 ng/L), and eGFR (45 mL/min/1.73m2) used in published staging models for AL and ATTR cardiac amyloidosis showed no association between abnormal biomarker level and adverse clinical outcome (p>0.05). In contrast, stratification by HGF level of 310 pg/mL (identified by the Youden Index for cardiac involvement by AL and ATTR in our cohort) showed that elevated HGF was associated with worse clinical outcomes (p=0.0211). Furthermore, event-free survival was worse in patients with elevated HGF, with survival curves diverging soon after enrollment (p=0.0730).
HGF is Prognostic in Cardiac Amyloidosis
Conclusions
Elevated HGF is associated with worse clinical outcomes in patients with AL and ATTR cardiac amyloidosis and has potential for clinical utility.

Abstract
BACKGROUND Intravenous thrombolysis is considered to be the standard reperfusion therapy for acute ischemic stroke, but its application is limited by high risk of hemorrhagic transformation (HT) after thrombolysis. AIM This study aimed to identify risk factors of HT after intravenous thrombolysis. METHODS Patients with acute ischemic stroke receiving rt-PA thrombolysis from February 2013 to January 2018 were retrospectively reviewed. They were divided into HT group and non-HT group based on cranial computed tomography. Data of all patients were collected and analysed by univariate analysis and stepwise logistic regression analysis. RESULTS A total of 403 patients were enrolled and their age ranged from 13 to 86 years, with an average age of 67.01 ± 31.88 years. 136 (33.7%) patients were females. The average time from disease onset to thrombolysis was 52.05 ± 20.12 min, and 46 patients (11.4%) had HT after thrombolysis. We found significant differences in activated partial thromboplastin time, fibrinogen value, platelet value and smoking before thrombolysis between HT and non-HT group (P < 0.05). CONCLUSION Smoking, prolongation of activated partial thromboplastin time, low fibrinogen levels and low platelet counts are associated with the risk of HT and could help the selection of thrombolytic patients to avoid HT.

Abstract
Objective: To investigate the in vivo kinematics of the lumbar degenerative spondylolysis (LDS) in senile patients. Methods: From March to October in 2014, nine L(4-5) LDS patients [mean age (74±9) years] and nine healthy volunteers [mean age, (54±4) years] were recruited. Combined fluoroscopy and CT scanning technique were used to obtain the three dimension kinematic data of the vertebral anatomical structures (vertebral body anterior margin, vertebral body posterior margin, facet joints and spinous process) in various postures (supine, standing, flexion and extension) under physical loads, and to compare the stability of different anatomical structures. The L(4-5) segmental disc angle was also measured in different postures. Paired-samples t test was applied to compare the displacement differences between the two groups. Results: During flexion-extension motion, all anatomical structures of the LDS group were slightly larger than those in normal group, but the statistical difference was not obvious (all P>0.05). For normal group, in anterior-posterior and cranial-caudal direction, sub-movement analysis showed that the anterior vertebral body margin at the flexion range of motion [(-1.07±0.84) mm, (-1.27±1.01) mm] were larger than the extension range of motion [(0.66±1.38) mm, (0.63±0.99) mm] (t=3.21, 4.03, both P<0.05). Whereas for LDS group, in anterior-posterior and cranial-caudal direction, sub-movement analysis showed that the anterior vertebral body margin at the extension range of motion [(1.46±1.26) mm, (1.17±0.54) mm] were significantly greater than the flexion range of motion [(-0.43±0.47) mm, (-0.45±1.24) mm] (t=4.22, 3.59, both P<0.05). The disc angles of the LDS group were all smaller than those in normal group, but the statistical difference was not obvious (all P>0.05). However, the disc angles were significantly different under different postures, the flexion were both the smallest in the normal group and LDS group. Conclusions: The senile LDS patients may not necessarily have instability, stability may also occur in these patients. Increasing extension range of motion is one of the kinematic characteristics in senile patients with LDS. The intervertebral stability should be taken into account, but if instability develops, surgical procedure should be suggested for elderly patients with LDS.

Abstract
BACKGROUND We conducted a single-arm phase II trial to evaluate the efficacy and adverse effects (AEs) of an anti-epidermal growth factor receptor monoclonal antibody, nimotuzumab, combined with cisplatin and 5-fluorouracil (PF) as first-line treatment in recurrent metastatic nasopharyngeal carcinoma after radical radiotherapy. METHODS Patients who met the eligibility criteria were recruited from ten institutions (ClinicalTrials.gov; NCT01616849). A Simon optimal two-stage design was used to calculate the sample size. All patients received weekly nimotuzumab (200 mg) added to cisplatin (100 mg/m2 D1) and 5-fluorouracil (4 g/m2 continuous infusion D1-4) every 3-weekly for a maximum of six cycles. Primary end point was objective response rate (ORR). Secondary end points included disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and AEs. RESULTS A total of 35 patients were enrolled (13 in stage 1 and 22 in stage 2). Overall ORR and DCR were 71.4% (25/35) and 85.7% (30/35), respectively. Median PFS and OS were 7.0 (95% CI 5.8-8.2) months and 16.3 (95% CI 11.4-21.3) months, respectively. Unplanned exploratory analyses suggest that patients who received ≥2400 mg nimotuzumab and ≥4 cycles of PF had superior ORR, PFS and OS than those who did not (88.9% versus 12.5%, P < 0.001; 7.4 versus 2.7 months, P = 0.081; 17.0 versus 8.0 months, P = 0.202). Favourable subgroups included patients with lung metastasis [HROS 0.324 (95% CI 0.146-0.717), P = 0.008] and disease-free interval of >12 months [HROS 0.307 (95% CI 0.131-0.724), P = 0.004], but no difference was observed for metastatic burden. The only major grade 3/4 AE was leukopenia (62.9%). CONCLUSION Combination nimotuzumab-PF chemotherapy demonstrates potential efficacy, and is well tolerated as first-line chemotherapy regimen in recurrent metastatic nasopharyngeal carcinoma.

Abstract
Abstract
Purpose: Statins may mediate suppression of molecular pathways conferring benefit in cancer. Statins have shown anti-tumor effects in preclinical studies and have been associated with decreased recurrence and improved disease-specific survival. While designed to target cholesterol biosynthesis, statins can also have liver, bone and brain effects. We collected data on statin use in the S0307 adjuvant bisphosphonate trial to test the hypothesis that statin use may decrease risk of recurrence to liver, bone and brain as well as second primary (contralateral) breast cancers, and may act synergistically with bisphosphonates to decrease the risk of recurrence to bone.
Patients and Methods: In S0307, 6097 patients diagnosed with Stage I-III breast cancer who had undergone surgery and were receiving adjuvant systemic therapy were randomized to receive zoledronic acid, clodronate, or ibandronate for 3 years. No significant difference was found in disease-free survival (DFS) among the 3 groups, including a sub-analysis of patients > age 55. Statin use was infrequent in younger women in S0307, consequently we analyzed statin use in those > age 55. Cox proportional hazard models were used to determine which variables were independently associated with DFS and to estimate hazard ratios (HR) and 95% confidence intervals (CI).
Results: Among women aged ≥ 55 years, 684 (27%) reported taking a statin at baseline and 1,848 did not. Both groups were similar in terms of hormone receptor and HER2 status (p = 0.82). Median age in the statin group was 64.3 versus 61.0 years in the no statin group, mean BMI 31.2 v. 29.5, mean tumor size 2.1cm v. 2.3cm, negative lymph nodes 60% v. 54%, Stage I disease 47% v. 36%, and receipt of chemotherapy 62% v. 71% (all p < 0.01). In the statin group, 122 (17.8%) experienced a DFS event compared to 313 (16.9%) in the no statin group (HR 1.18, CI 0.95-1.46). No difference was observed by statin use in overall recurrence (p=0.28), distant recurrence (p=0.64), or recurrences to the bone (p=0.64), liver (p=0.38) or brain (p=0.65) at initial recurrence. There was no synergy between statin use and specific bisphosphonates.

Conclusions: We found no evidence that statins reduce risk of second primary breast cancers or distant metastases among post-menopausal women with early-stage breast cancer. Despite promising preclinical data, they did not appear to act in synergy with a specific bisphosphonate. Though women in the statin group had less advanced disease at study entry, statin use was not associated with improved DFS. Results are limited by lack of information about type of statin used, adherence, or initiation of statin in control group.

Abstract
OBJECTIVE Sudden sensorineural hearing loss (SSHL) is a multifactorial disorder with high heterogeneity, thus the outcomes vary widely. This study aimed to develop predictive models based on four machine learning methods for SSHL, identifying the best performer for clinical application. DESIGN Single-centre retrospective study. SETTING Chinese People's liberation army (PLA) hospital, Beijing, China. PARTICIPANTS A total of 1220 in-patient SSHL patients were enrolled between June 2008 and December 2015. MAIN OUTCOME MEASURES An advanced deep learning technique, deep belief network (DBN), together with the conventional logistic regression (LR), support vector machine (SVM) and multilayer perceptron (MLP) were developed to predict the dichotomised hearing outcome of SSHL by inputting six feature collections derived from 149 potential predictors. Accuracy, precision, recall, F-score and the area under the receiver operator characteristic curves (ROC-AUC) were exploited to compare the prediction performance of different models. RESULTS Overall the best predictive ability was provided by the DBN model when tested in the raw data set with 149 variables, achieving an accuracy of 77.58% and AUC of 0.84. Nevertheless, DBN yielded inferior performance after feature pruning. In contrast, the LR, SVM and MLP models demonstrated opposite trend as the greatest individual prediction powers were obtained when included merely three variables, with the ROC-AUC ranging from 0.79 to 0.81, and then decreased with the increasing size of input features combinations. CONCLUSIONS With the input of enough features, DBN can be a robust prediction tool for SSHL. But LR is more practical for early prediction in routine clinical application using three readily available variables, that is time elapse between symptom onset and study entry, initial hearing level and audiogram.

Abstract
We have measured excess carrier lifetime in silicon using photoexcited muon spin spectroscopy. Positive muons implanted deep in a wafer can interact with the optically injected excess carriers and directly probe the bulk carrier lifetime while minimizing the effect from surface recombination. The method is based on the relaxation rate of muon spin asymmetry, which depends on the excess carrier density. The underlying microscopic mechanism has been understood by simulating the four-state muonium model in Si under illumination. We apply the technique to different injection levels and temperatures, and demonstrate its ability for injection- and temperature-dependent lifetime spectroscopy.

Abstract
Multiferroic hybrid structures PbZr0.2Ti0.8O3 (PZT)/La0.7Sr0.3MnO3 (LSMO) and PZT/MgO/LSMO were epitaxially deposited on (001) Nb:SrTiO3 crystals. Crystallinity and ferroelectric domain structures were investigated for the PZT/LSMO heterostructure. Interestingly, relatively high non-volatile magnetoelectric coupling effects were observed in both heterostructures at room temperature. The change of chemical valence for Mn and Ti at the PZT/MgO/LSMO interface may play a dominant role rather than external strain or orbital reconstruction, which lead to a large modulation of the magnetization. Correspondingly, the transport behavior of the PZT/MgO/LSMO heterostructure is investigated to confirm the role of oxygen vacancies motion. Our result indicates that the PZT/MgO/LSMO heterostructure have a promising application for future high-density non-volatile memories.

Abstract
This study aims to analyse the clinical effects of continuous blood purification (CBP) in children with severe sepsis to form a basis for CBP application in this context. One hundred and twenty children with severe sepsis treated in Binzhou Peoples Hospital, Shandong, China, from June 2013 to June 2014 were divided into two groups, a treatment and a control group, depending on parental preference. The control group was treated conventionally, and the treatment group underwent CBP in addition to conventional therapy. Cardiovascular and respiratory parameters were measured on admission and after 72 h. This study also assayed interleukin (IL)-8 and tumour necrosis factor (TNF)-α levels, and monitored clinical outcomes and prognosis. The cardiovascular and respiratory parameters of the treatment group improved to a significantly greater extent than did those of the control group (all P less than 0.05). After treatment, the levels of IL-8, IL-6, IL-10, and TNF-α declined in both groups, but more so in the treatment group (all P<0.05). The white blood cell count and C-reactive protein level fell more in the treatment than control group, with statistical significance (both P less than 0.05). CBP remarkably improved the cardiovascular and respiratory functions of children with severe sepsis, probably by eliminating factors mediating inflammation.

Abstract
OBJECTIVE Deep vein thrombosis (DVT) is one common vascular complication after trauma or surgery. Macrophage plays an important role in recanalization of thrombosis and monocyte chemotactic protein 1 (MCP-1) has a potent chemotactic role for macrophage. This study investigated the role of MCP-1 and macrophage in DVT thrombolysis. MATERIALS AND METHODS DVT mice model was established for evaluating thrombosis grades, and divided into DVT, DVT + MCP-1 recombinant protein, and DVT + MCP-1 neutralizing antibody groups. MCP-1 mRNA and protein expression, weight/length ratio of thrombosis were tested at 1, 5, 9 and 15 day after DVT. F4/80 protein expression in thrombosis on day 9 was measured to reflect infiltration of macrophage. RESULTS DVT model mice had thrombosis grade at 2.47 ± 0.22 whilst no thrombosis occurred in sham group. DVT group had gradually increased MCP-1 mRNA and protein expression, which reached the peak at day 9, followed by decreased expression. Thrombosis weight/length ratio showed decreasing trends. MCP-1 protein injection significantly elevated MCP-1 expression, decreased thrombosis weight/length ratio, and elevated macrophage infiltration. Injection of MCP-1 antibody remarkably decreased MCP-1 expression, elevated thrombosis weight/length ratio and macrophage infiltration. CONCLUSIONS MCP-1 up-regulation participates in macrophage chemotaxis and thrombolysis after DVT formation. The blockade of MCP-1 weakens its thrombolysis effects.

Abstract
Polyphenols in Eucalyptus leaves (PE) were value resources due to various pharmacological activities, but data on the effect on laying hens are very scare. This study was conducted to determine the effect of PE on the laying performance, egg traits, meat quality, antioxidant status and liver tissues of laying hens. One hundred and twenty 256-day-old Yueqinhuang laying hens were randomly assigned to four treatment groups (different levels of PE at 0, 0.5, 0.8 and 1.2 g/kg diet) for 63 days with 15 replicates per group. Addition of 0.8 g/kg PE not only improved the egg trait by increasing the eggshell thickness and decreasing MDA production and cholesterol content in the egg yolk, but also significantly enhanced meat quality of hens, as suggested by the increase pH45 min (p < .01) and a* value, and decrease drip loss rate (p < .01). Meanwhile, under acute ethanol-induced oxidative damage condition, supplementation of 0.8 g/kg PE enhanced the serum antioxidant status by increasing enzymatic activities (GSH-PX, T-SOD, T-AOC), inhibited oxidative damage and provided protective effect to liver tissue. In conclusion, addition of 0.8 g/kg PE not only improved the egg traits and meat quality without obvious adverse effects, but also increased the serum antioxidant status of the hens and protected their liver tissue from ethanol-induced oxidative damage. This study indicated that PE could be utilized as an effective feed additive for laying hens to improve health performance and egg traits.
