Abstract
We describe a GPU-enabled approach for real-time optical frequency comb spectroscopy in which data is recorded, Fourier transformed, normalized, and fit at data rates up to 2.2 GB/s. As an initial demonstration we have applied this approach to rapidly interrogate the motion of an optomechanical accelerometer through the use of an electro-optic frequency comb. We note that this approach is readily amenable to both self-heterodyne and dual-comb spectrometers for molecular spectroscopy as well as a photonic readout where the approach's agility, speed, and simplicity are expected to enable future improvements and applications.

Abstract
PURPOSE/OBJECTIVE(S) Patients with N2 non-small cell lung cancer (NSCLC) were heterogeneous groups and required further stratification. The International Society for the Study of Lung Cancer (IASLC) added new descriptors of three sub-stages for stage N2 NSCLC: N2 at a single station without N1 involvement (N2a1), N2 at a single station with N1 involvement (N2a2), and N2 at multiple stations (N2b). This study aimed to investigate the efficacy of postoperative radiotherapy (PORT) for patients with these N2 descriptors. MATERIALS/METHODS Patients with histologically confirmed NSCLC after complete resection and divided into PORT group and non-PORT group. The primary endpoint was DFS. The second endpoints were overall survival (OS) and locoregional recurrence-free survival (LRFS). Propensity-score matching (PSM) of baseline characteristics between the PORT and non-PORT groups was used for validation. RESULTS Totally 1832 patients were enrolled, including 308 N2a1 patients, 682 N2a2 patients, and 842 N2b patients. The median follow-up time was 50.1 months. The survival outcomes of the PORT and non-PORT groups before PSM were shown in Table 1. For patients with N2a1, PORT could not improve the DFS (median DFS of the PORT group and the non-PORT group: not reached vs. 46.8 months, P = 0.41), OS (P = 0.85), or LRFS (P = 0.32), which were consistent with the multivariate analysis and data after the PSM. For patients with N2a2, PORT significantly improved the DFS (median DFS 29.7 vs. 22.2 months, P = 0.02), OS (P = 0.03), and LRFS (P = 0.01). The multivariate analysis and data after the PSM confirmed the benefits in DFS and LRFS, but no benefit was observed in OS (multivariate analysis: HR 0.79, P = 0.18; median OS after PSM: 103.7 vs. 63.1 months, P = 0.34). For patients with N2b, PORT could not improve the DFS (median DFS 20.6 vs. 21.2 months, P = 0.39) but significantly improved the OS (P<0.001) and LRFS (P<0.001). However, the multivariate analysis showed that PORT significantly improved DFS (HR 0.81, P = 0.03), consistent with the data after the PSM (median DFS 20.6 and 17.6 months, P = 0.04). CONCLUSION PORT significantly improved the DFS and LRFS in patients with N2a2 and significantly improved the DFS, LRFS, and OS in patients with N2b. Patients with N2a1 could not benefit from PORT.

Abstract
PURPOSE/OBJECTIVE(S) Nearly 30% of patients with local advanced esophageal cancer achieved pathological complete response (pCR) after neoadjuvant chemoradiotherapy (nCRT), who may benefit from organ-preservation strategy under accurate prediction of pCR. We aimed to develop and validate machine learning models based on clinicohematological markers and MR radiomics to accurately predict pCR of esophageal cancer after nCRT. MATERIALS/METHODS In this multi-center study, eligible patients with esophageal cancer who received baseline MR scan (T2-weighted image) and nCRT plus surgery were enrolled between September 2014 and September 2022 at institution 1 (training set) and between December 2017 and August 2021 at institution 2 (testing set). Pre-nCRT and post-nCRT blood test results were collected to calculate hematological markers. Models were constructed by machine learning based on clinicohematological markers and MR radiomics to predict pCR. Area under the curve (AUC) and cut-off analysis were used to evaluate model performances. RESULTS Totally 154 patients (81 in the training set and 73 in the testing set) were enrolled. The combined model integrating pre-nCRT monocyte-to-lymphocyte ratio and 6 radiomics features achieved AUC of 0.800 (95% CI 0.671-0.918) in the testing set, with sensitivity of 79.2% (95% CI 62.5%-95.8%), specificity of 83.7% (95% CI 73.5%-93.9%), positive predictive value of 76.0% (95% CI 62.5%-90.0%), and negative predictive value of 89.6% (95% CI 82.0%-95.8%). CONCLUSION A machine learning model based on clinicohematological markers and MR radiomics to predict pCR after nCRT for patients with esophageal cancer was developed and validated, providing a novel tool for personalized treatment. It is necessary to further validate in more large datasets.

Abstract
PURPOSE/OBJECTIVE(S) Brain metastasis is one of the most common failure patterns of pⅢA-N2 non-small cell lung cancer (NSCLC) after complete resection. Prophylactic Cranial Irradiation (PCI) can improve intracranial control but not overall survival. Thus, it is particularly important to identify risk factors that are associated with brain metastasis and subsequently provide instructions for selecting patients who will optimally benefit from PCI. We have reported a nomogram model which was established based on the condition of histology, bronchial invasion, perineural invasion, and adjuvant chemotherapy, through which we can predict high risk brain metastases in patients with pⅢA-N2 NSCLC. The purpose of this study is to verify the accuracy of the nomogram model by using new cases information. MATERIALS/METHODS Between January 1, 2015 and December 31, 2019, patients of pⅢA-N2 NSCLC were retrospectively analyzed, to verify the consistency between actual and predictive brain metastases. The verification group was divided into two groups according to the years when genetic testing has been widely used in clinic (group1:2015-2016, group2:2017-2019). ROC curves and calibration curves were chosen for validation. RESULTS A total of 770 patients were enrolled in our retrospective study (group1:294 patients, group2: 476patients). The 1-, 3- and 5-year survival rates were 97.2%, 76.5%, 63.2% in group1, and 95.8%, 84.5%, 76.9% in group2, respectively. The 1-, 3- and 5-year brain metastasis rates were 7.9%, 19.7%, 25.8%, and 5.4%, 14.5%, 26.3% in group2, respectively. The AUC were 0.74 (95% CI:0.72 - 0.76) in group1, and 0.71(95% CI:0.70 - 0.73) in group 2.The 1.3.5-year calibration curves of the two groups show that the prediction is in good agreement with the actual observation. CONCLUSION The nomogram model can predict brain metastases high risk patients with pⅢA-N2 NSCLC. Whether gene test or not, it can be used as a basis to screening out patients of high-risk brain metastases in future clinical trials for PCI.

Abstract
PURPOSE/OBJECTIVE(S) Locoregional recurrence is a common failure pattern for patients with completely resected pIIIA-N2 NSCLC. The salvage thoracic radiotherapy is administered in some pIIIA-N2 NSCLC patients despite postoperative radiotherapy (PORT). Salvage thoracic radiotherapy could be well tolerated and might improve survival from several small sample retrospective studies, while the high-level clinical evidence is presently lacking. We conducted this retrospective case control study to demonstrate the efficacy of salvage thoracic radiotherapy for completely resected pIIIA-N2 NSCLC patients with locoregional recurrence. MATERIALS/METHODS Between January 2003 and June 2019, patients who had undergone lobectomy or pneumonectomy plus mediastinal lymph node dissection or systematic sampling in our single institution were retrospectively reviewed. Those with pⅢA-N2 NSCLC that did not receive PORT and suffered locoregional recurrence being the first treatment failure were enrolled. The log-rank test was used to analyze differences between the groups, and the Kaplan-Meier method was used for survival analysis. Univariate and multivariate analyses using Cox proportional hazards regression models were performed to evaluate potential prognostic factors for survival. Statistically significant difference was set as p<0.05. RESULTS Of all the patients with pⅢA-N2 NSCLC reviewed, 105 suffered locoregional recurrence as the first treatment failure and didn't receive PORT. Among these patients, 51 (48.6%) received salvage thoracic radiotherapy and 54 (51.4%) did not. The median OS was 47.7 months of all patients. Survival analysis showed that the median OS in salvage thoracic radiotherapy group (69.0 months) was significantly longer than that in non-salvage thoracic radiotherapy group (37.7 months) (p = 0.029). For patients of EGFR wild type, salvage thoracic radiotherapy group had significantly longer median OS of 69.0 months compared with non-salvage thoracic radiotherapy group of 31.3 months (p = 0.004). When assessed by histological types, salvage thoracic radiotherapy significantly improved the survival of patients with lung squamous cell carcinoma with median OS not reached compared with non-salvage thoracic radiotherapy group of 31.3 months (p<0.001), while in patients with non-squamous cell carcinoma, this survival benefit was not observed (p = 0.829). CONCLUSION Salvage thoracic radiotherapy is an effective treatment for completely resected pIIIA-N2 NSCLC patients that have not received PORT and suffered post-operative locoregional recurrence.

Abstract
4D printing has a great potential for the manufacturing of soft robotics and medical devices. The alliance of digital light processing (DLP) 3D printing and novel shape-memory photopolymers allows for the fabrication of smart 4D-printed medical devices in high resolution and with tailorable functionalities. However, most of the reported 4D-printed materials are nondegradable, which limits their clinical applications. On the other hand, 4D printing of biodegradable shape-memory elastomers is highly challenging, especially when transition points close to physiological temperature and shape fixation under ambient conditions are required. Here, we report the 4D printing of biodegradable shape-memory elastomers with tailorable transition points covering physiological temperature, by using poly(D,L-lactide-co-trimethylene carbonate) methacrylates at various monomer feed ratios. After the programming step, the high-resolution DLP printed stents preserved their folded shape at room temperature, and showed efficient shape recovery at 37 °C. The materials were cytocompatible and readily degradable under physiological conditions. Furthermore, drug-loaded devices with tuneable release kinetics were realized by DLP-printing with resins containing polymers and levofloxacin or nintedanib. This study offers a new perspective for the development of next-generation 4D-printed medical devices.

Single-modulator, direct frequency comb spectroscopy via serrodyne modulation. OPTICS LETTERS 2023; 48:892-895.

Abstract
Traditional electro-optic frequency comb spectrometers rely upon the use of an acousto-optic modulator (AOM) to provide a differential frequency shift between probe and local oscillator (LO) legs of the interferometer. Here we show that these modulators can be replaced by an electro-optic phase modulator (EOM) which is driven by a sawtooth waveform to induce serrodyne modulation. This approach enables direct frequency comb spectroscopy to be performed with a single dual-drive Mach-Zehnder modulator (DD-MZM), allowing for lower differential phase noise. Further, this method allows for simpler production of integrated photonic comb spectrometers on the chip scale.

MicroRNA-130a attenuates cardiac fibrosis after myocardial infarction through TGF-β/Smad signaling by directly targeting TGF-β receptor 1. Bioengineered 2022; 13:5779-5791.

Abstract
Cardiac fibrosis is a common pathophysiological change associated with myocardial infarction (MI), and while there is evidence that miR-130a plays an important role in a variety of fibrotic diseases, its role in the cardiac fibrosis during MI is unclear. Our study aimed to assess miR-130a’s ability to modulate cardiac fibrosis post-MI and uncover its potential molecular mechanisms. miR-130a was significantly downregulated in infarcted myocardium and hypoxic cardiac fibroblasts (CFs), whereas TGF-β, α-SMA, collagen 1 (Col-1), and TGF-β receptor 1 (TGFBR1) were upregulated. We transfected mice with AAV-9 carrying miR-130a and found that miR-130a overexpression statistically improved cardiac function and reduced the area of cardiac fibrosis in mice post-MI. Eukaryotic transcriptome sequencing and dual-luciferase reporter assay results verified that Tgfbr1 was a target gene of miR-130a. miR-130a inhibition heightened Col-1, α-SMA, and TGFBR1 expressions and Smad3 phosphorylation levels in CFs; however, these increments were suppressed by the overexpression of miR-130a. Meanwhile, co-transfection with TGFBR1 weakened miR-130a’s ability to inhibit α-SMA and Col-1 expression. These findings suggest that miR-130a exerts antifibrotic properties by directly targeting TGFBR1 to regulate TGF-β/Smad signaling and inhibit the conversion of CFs to myofibroblasts. Thus, miR-130a is a promising therapeutic target for alleviating cardiac fibrosis.

Abstract
OBJECTIVES Although low muscle mass may make an under-appreciated contribution to increasing the risk of cardiovascular diseases, no prospective studies have explored the association between low muscle mass and carotid atherosclerosis. We investigated whether muscle mass was related to a higher carotid intima-media thickness (C-IMT) and carotid artery plaque in a community-based population. METHODS The study included 1,253 asymptomatic participants without known cardiovascular disease, who underwent carotid ultrasonography at baseline in 2013-2014 and received a re-examination in 2015-2016. The skeletal muscle mass index was estimated using a bioelectrical impedance analyzer. We assessed the relationship between the skeletal muscle mass index and the development of C-IMT and carotid plaque, both, using multivariate-adjusted logistic regression models. RESULTS During the follow up, 400 (51.0%) subjects with normal C-IMT at baseline developed elevated C-IMT and 215 (17.2%) subjects developed carotid plaque. The risk of elevated C-IMT occurrence linearly decreased with an increase in skeletal muscle mass index quintiles or its continuous data, after multivariate-adjustment in men and women, respectively (both P for trend < 0.05; both P < 0.05). Subgroup analyses showed that this association was BMI-dependent. Besides, there was an inverse association between a high skeletal muscle mass index and carotid artery plaque in women, but the association disappeared after multivariate adjustment. In men, the skeletal muscle mass index was not associated with the incidence of carotid plaque. CONCLUSIONS Skeletal muscle mass was inversely associated with the incidence of carotid atherosclerosis, suggesting muscle mass maintenance may play a role in modifying atherosclerosis.

Abstract
BACKGROUND This study assessed the effects of adding tislelizumab to first-line standard-of- care chemotherapy on the health-related quality of life (HRQoL) of patients with advanced squamous non-small cell lung cancer (sq-NSCLC). PATIENTS AND METHODS Patients in this open-label, multicenter, phase 3 RATIONALE 307 trial were randomized to one of the three arms: tislelizumab plus carboplatin and paclitaxel (Arm A), tislelizumab plus carboplatin and nab-paclitaxel (Arm B), or paclitaxel plus carboplatin (Arm C). HRQoL was measured using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and the EORTC Quality of Life Questionnaire Lung Cancer 13-item module (QLQ-LC13). Mean score change from baseline at Weeks 6 and 12 in the QLQ-C30's global health status/quality of life (GHS/QoL), fatigue, and physical functioning scores and QLQ-LC13 lung cancer specific subscales were examined. Time to deterioration was estimated for the GHS/QoL score. RESULTS A total of 355 sq-NSCLC patients received at least one dose of study drug and completed at least one HRQoL assessment. The GHS/QoL scores improved in Arms A and B relative to Arm C at Weeks 6 and 12. Arms A and B also experienced a reduction in most lung cancer-specific symptoms relative to Arm C. Time to deterioration of GHS/QoL was not reached by any of the three arms. CONCLUSIONS The addition of tislelizumab to platinum-based chemotherapy is associated with improvements in sq-NSCLC patients' HRQoL, especially in GHS/QoL and most importantly in lung cancer-specific symptoms including coughing, dyspnea, and hemoptysis.

Abstract
Corrected QT (QTc) interval prolongation has been associated with poor patient prognosis. In this study, we assessed the effects of different drugs and cardiac injury on QTc interval prolongation in patients with coronavirus disease 2019 (COVID-19).The study cohort consisted of 395 confirmed COVID-19 cases from the Wuhan Union Hospital West Campus. All hospitalized patients were treated with chloroquine/hydroxychloroquine (CQ/HCQ), lopinavir/ritonavir (LPV/r), quinolones, interferon, Arbidol, or Qingfei Paidu decoction (QPD) and received at least 1 electrocardiogram after drug administration.Fifty one (12.9%) patients exhibited QTc prolongation (QTc ≥ 470 ms). QTc interval prolongation was associated with COVID-19 severity and mortality (both P < .001). Administration of CQ/HCQ (odds ratio [OR], 2.759; 95% confidence interval [CI], 1.318-5.775; P = .007), LPV/r (OR, 2.342; 95% CI, 1.152-4.760; P = .019), and quinolones (OR, 2.268; 95% CI, 1.171-4.392; P = .015) increased the risk of QTc prolongation. In contrast, the administration of Arbidol, interferon, or QPD did not increase the risk of QTc prolongation. Notably, patients treated with QPD had a shorter QTc duration than those without QPD treatment (412.10 [384.39-433.77] vs 420.86 [388.19-459.58]; P = .042). The QTc interval was positively correlated with the levels of cardiac biomarkers (creatine kinase-MB fraction [rho = 0.14, P = .016], high-sensitivity troponin I [rho = .22, P < .001], and B-type natriuretic peptide [rho = 0.27, P < .001]).In conclusion, QTc prolongation was associated with COVID-19 severity and mortality. The risk of QTc prolongation was higher in patients receiving CQ/HCQ, LPV/r, and quinolones. QPD had less significant effects on QTc prolongation than other antiviral agents.

Abstract
Background:Intestinal flora disorder and immune abnormalities have been reported in systemic lupus erythematosus (SLE) patients1,2. Berberine (BBR) showed significant effects in regulating the intestinal flora, repairing gut barriers and regulating immune cells3,4. While few reports mentioned the abnormal gut microbiota and metabolites in Chinese SLE patients.Objectives:Our investigation tried to illustrate the relationship between gut microbiota, intestinal metabolites and disease activity in Chinese SLE patients. And the effect of BBR to intestinal dysbacteriosis, multiple organ damages and over-activated immune system in MRL/Lpr mice.Methods:16S high-throughput (16S rRNA) sequence, qRT-PCR and gas chromatography technology were used to determine the gut microbiota and metabolites in 104 SLE patients from Affiliated Hospital of Nantong University, China. BBR was orally treated to the MRL/Lpr mice in low, medium and high doses. After 6 weeks treatment, mice were sacrificed. Serum, faeces and organs were collected for further studies.Results:Chinese SLE patients showed higher abundance of Bacteroidetes and lower abundance of Firmcutes. The results of qRT-PCR showed high Firmcutes/Bacteroidetes (F/B) ratio of SLE patients. The F/B ratio was negative correlated with SLE disease activity index (SLEDA) score. Almost all the tested short-chain fatty acids (SCFAs) found statistically significant results in SLE and LN (lupus nephritis) patients, especially the propanoic acid and butyric. BBR altered the relative abundance of Bacteroides and Verrucomicrobia and the butyric acid content in colon of MRL/Lpr mice. The increase of tight junction protein also indicated the gut barrier was repaired by BBR. Treg and Tfr cells in spleen and mesenteric lymph node (MLN) were increased. These results revealed a positive therapeutic effect of berberine on SLE from gut microbiota to immune status.Conclusion:Our study highlights current status of intestinal dysbacteriosis in Chinese patients with SLE and differences in intestinal metabolites among patients with different disease states. The regulation of intestinal flora and the repairment of gut barrier by intestinal metabolites in BBR treated mice seemed to be the factor that directed the immune responses and disease outcomes. The ultimate goal of our study was to determine the beneficial effects of regulating the gut microbiota on the treatment of SLE. The application of berberine is a relatively safe and convenient way. In the coming investigations, we plan to focus on the study of berberine and its metabolites on intestinal function and systemic immunity.References:[1]Guo, M. et al.

Adaptability of winter wheat Dongnongdongmai 1 (Triticum aestivum L.) to overwintering in alpine regions. PLANT BIOLOGY (STUTTGART, GERMANY) 2021; 23:445-455.

Abstract
Long winters led to a one-crop-a-year cultivation system until the winter wheat Dongnongdongmai 1 (Dn1) was successfully cultivated in northeast China. This crop variety is resistant to extremely low temperatures (-35 °C). To better understand the adaptability of winter wheat Dn1 to low temperatures, gas chromatography time-of-flight mass spectrometry (GC-TOF/MS) and metabolomics analysis was conducted on the tillering nodes of winter wheat during the overwintering period. Enzyme-regulating genes of the metabolic products were also quantitatively analysed. The metabolomic results for the tillering nodes in the overwintering period showed that disaccharides had a strong protective effect on winter wheat Dn1. Amino acid metabolism (i.e. proline, alanine and GABA) changed significantly throughout the whole wintering process, whereas organic fatty acid metabolism changed significantly only in the late stage of overwintering. This result indicates that the metabolites used by winter wheat Dn1 differ in different overwintering stages. The relationship between field temperature and metabolite changes in winter wheat Dn1 during overwintering periods is discussed, and disaccharides were identified as the osmotic stress regulators for winter wheat Dn1 during the overwintering process, as well as maintenance of the carbon and nitrogen balance by monosaccharides, amino acids and lipids for cold resistance.

Abstract
Electro-optic frequency combs were employed to rapidly interrogate an optomechanical sensor, demonstrating spectral resolution substantially exceeding that possible with a mode-locked frequency comb. Frequency combs were generated using an integrated-circuit-based direct digital synthesizer and utilized in a self-heterodyne configuration. Unlike approaches based upon laser locking, the present approach allows rapid, parallel measurements of full optical cavity modes, large dynamic range of sensor displacement, and acquisition across a wide frequency range between DC and 500 kHz. In addition to being well suited to measurements of acceleration, this optical frequency comb-based approach can be utilized for interrogation in a wide range of cavity optomechanical sensors.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) continues to impact populations around the globe. Information regarding the incidences and implications of arrhythmias in COVID-19 is limited. METHODS A total of 463 patients with COVID-19 and who had at least one electrocardiogram recording from February 1 to March 19, 2020, in Wuhan Union Hospital were enrolled in the study. RESULTS Arrhythmias occurred in 85 of 463 (18.4%) patients: atrial arrhythmias in 10.2%, junctional arrhythmias in 0.2%, ventricular arrhythmias in 3.5%, and conduction block in 7.3%. Compared with patients without arrhythmias, those with arrhythmias had higher mortality, both during the time from symptom onset (p < 0.001) and from admission to follow-up (p < 0.001). The frequencies of severe COVID-19 (44.7% vs. 21.2%; p < 0.001) and death (25.9% vs. 10.1%; p < 0.001) were higher in patients with arrhythmias than in those without arrhythmias. Atrial arrhythmias and ventricular arrhythmias could predict severity and mortality, their odds ratios (OR) were 4.45 (95% confidence interval [CI] 2.35 to 8.40), 5.80 (95% CI 1.89 to 17.76) respectively for severity, and were 3.51 (95% CI 1.74 to 7.08), 3.41 (95% CI 1.13 to 10.24) respectively for mortality. High levels of interleukin-6 (IL-6) and IL-10 were associated with the occurrence of arrhythmias (all p < 0.05). CONCLUSION Arrhythmias were significantly associated with COVID-19 severity and mortality. Atrial arrhythmia was the most frequent arrhythmia type. IL-6 and IL-10 levels can predict the risk of arrhythmias in COVID-19 patients.

Abstract
Oxygen isotope speleothem records exhibit coherent variability over the pan-Asian summer monsoon (AM) region. The hydroclimatic representation of these oxygen isotope records for the AM, however, has remained poorly understood. Here, combining an isotope-enabled Earth system model in transient experiments with proxy records, we show that the widespread AM δ18Oc signal during the last deglaciation (20 to 11 thousand years ago) is accompanied by a continental-scale, coherent hydroclimate footprint, with spatially opposite signs in rainfall. This footprint is generated as a dynamically coherent response of the AM system primarily to meltwater forcing and secondarily to insolation forcing and is further reinforced by atmospheric teleconnection. Hence, widespread δ18Op depletion in the AM region is accompanied by a northward migration of the westerly jet and enhanced southwesterly monsoon wind, as well as increased rainfall from South Asia (India) to northern China but decreased rainfall in southeast China.

Abstract
An integrated multi-trophic aquaculture (IMTA) system, with one fish cage model surrounded by an island and shellfish rafts, was used in the current study. Planktonic and sediment bacterial communities in the IMTA system were monitored over four seasons in 2019. In both plankton and sediment samples, the most dominant phyla were Proteobacteria and Bacteroidota. Sediment bacterial samples were more similar and had higher levels of biodiversity than planktonic bacterial samples. Obvious seasonal variations were found in plankton samples, but not in sediment samples. No obvious inter-site variations in planktonic and sediment bacteria (fish cages, shellfish rafts and control sites) were found and the results suggested that no obvious impact of feeding operations in fish culture cage model on bacterial communities in the IMTA system was observed in this study. Based on the sequence data, some faecal indicator bacteria and potentially pathogenic bacterial species were detected. According to the results, the bacterial water quality in the IMTA system was acceptable. PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States) analysis revealed that the primary difference in potential functional roles of planktonic and sediment bacteria was amino acid transport and metabolism, which was active in different seasons.

Abstract
Methylphenidate (MPH) is used as the first-line treatment for attention-deficit hyperactivity disorder. However, there are concerns that this treatment may be associated with increased risk of retinal damage. This study was to investigate cytotoxicity of MPH on photoreceptor cells and explore its underlying mechanisms. MPH-caused cell toxicity was established in 661 W cells. Cytotoxicity was evaluated by 3-(4,5-dimethylthiazol)-2,5-diphenyltetrazolium-bromid and lactate dehydrogenase assays. Oxidative stress was measured by the markers: glutathione (GSH) reductase, catalase, and superoxide dismutase activities as well as GSH, reactive oxygen species, and malondialdehyde levels. Gene and protein expression was detected by real-time polymerase chain reaction (PCR) and western blot, respectively. Results showed that MPH decreased 661 W cell viability, increased caspase-3/9 activities, and induced oxidative stress. Furthermore, MPH treatment increased messenger RNA (mRNA) expression of Beclin-1 and microtubule-associated protein 1A/1B-light chain 3B (LC3B) protein expression in 661 W cells, suggesting autophagy was induced. MPH treatment also upregulated p-JAK1/p-STAT1 protein expression. These data demonstrated that MPH could increase oxidative stress in photoreceptor cells to cause cell toxicity via autophagy, providing the scientific rationale for the photoreceptor cell damage caused by the MPH administration.

Abstract
Objective: To determine whether 60 Gy is superior to standard 50 Gy for definitive concurrent chemoradiation(CCRT) in esophageal squamous cell carcinoma (ESCC) using modern radiation technology in a phase Ⅲ prospective randomized trial. Methods: From April 2013 to May 2017, 331 patients from 22 hospitals who were pathologically confirmed with stage ⅢA-ⅣA ESCC were randomized to 60 Gy or 50 Gy with random number table. Total of 305 patients were analyzed, including 152 in 60 Gy group and 153 in 50 Gy group. The median age was 63 years, 242(79.3%) males and 63(20.7%) females. The median length of primary tumor was 5.6 cm. The clinical characteristics between two groups were comparable. All patients were delivered 2 Gy per fraction, 5 fractions per week. Concurrent weekly chemotherapy with docetaxel (25 mg/m(2)) and cisplatin (25 mg/m(2)) and 2 cycles consolidation chemotherapy with docetaxel (70 mg/m(2)) and cisplatin (25 mg/m(2), d1-3) were administrated. The primary endpoint was local/regional progression-free survival (LRPFS). The data were compared with Pearson chi-square test or Fisher's exact test. Results: At a median follow-up of 27.3 months, the disease progression rate was 37.5% (57/152), 43.8% (67/153) in the high and standard-dose group, respectively (χ(2)=1.251, P=0.263). The 1, 2, 3-year LRPFS rate was 75.4%, 56.8%, 52.1% and 74.2%, 58.4%, 50.1%, respectively (HR: 0.95, 95%CI: 0.69-1.31, P=0.761). The 1, 2, 3-year overall survival rate was 84.1%, 64.8%, 54.1% and 85.4%, 62.9%, 54.0%, respectively (HR: 0.98, 95%CI: 0.71-1.38, P=0.927). The 1, 2, 3-year progression-free survival rate was 70.8%, 54.2%, 48.5% and 65.5%, 51.9%, 45.1%, respectively (HR: 0.93, 95%CI: 0.68-1.26, P=0.621). The incidence rates in toxicities between the two groups were similar except for higher rate of severe pneumonitis in high dose group (χ(2)=11.596, P=0.021). Conclusions: The efficacy in disease control is similar between 60 Gy and 50 Gy using modern radiation technology concurrent with chemotherapy for ESCC. The 50 Gy should be recommended as the regular radiation dose with CCRT for ESCC.

Abstract
Background:Although the burden of comorbidities and infections in RA patients in the US is well established,1there is an evidence gap for RA patients in the US territory of PR.Objectives:To describe the patient demographics, clinical characteristics, and infection rates in patients with RA in PRMethods:A retrospective cohort of adults age ≥18 years from PR with ≥2 diagnosis of RA were identified using International Classification of disease codes (ICD-9 or ICD-10) on separate days from Jan 1, 2006 to June 30, 2018 using the Truven MarketScan™ database. Patients were divided into three treatment cohorts: no treatment, conventional disease-modifying anti-rheumatic drugs (csDMARD) user, and biologic DMARD (bDMARD) user. Patients in the no treatment group were followed from their first RA diagnosis date to the date of initiation of any DMARDs. The csDMARD users were followed from the initiation of csDMARD until the initiation of any bDMARD or targeted synthetic DMARDs (tsDMARDs). Patients were censored at the last observed medical claim if treatments were not initiated during follow-up. bDMARD users were followed from the date of initiation of bDMARD or tsDMARD until their last observed medical claim. Crude incidence rates /1000 person-years (PY) were reported for opportunistic infections (e.g. Mycobacterium, Cytomeglavirus, Candidiasis, and Chlamydial infections) and infections requiring hospitalisation.Results:Of the 623 patients in the cohort of RA patients from PR, majority were women (75.4%), aged 41-64 years (67.1%), employed full time (69.8%), with PPO health plan (89.4%), and with mean length of follow-up of 5.77 years from index RA diagnosis. Our results shows that cardiovascular conditions (CVD, hypertension, and hyperlipidemia) were the most prevalent comorbidities in PR patients with RA (Table 1), followed by diabetes (55.7%) in the total RA patient population. The crude IR/1000 PY for opportunistic infections was 23.35 for patients in the no treatment cohort, 48.52 for patients in csDMARD, and 28.31 for bDMARD users. For hospitalized infections, the crude IR/1000 PY was 26.00 for patients in the no treatment cohort, 22.08 for csDMARD users, and 41.90 for bDMARD users.Table 1.Patient Clinical CharacteristicsPatient CharacteristicsTotal PatientsNo TreatmentcsDMARD userbDMARD userN%N%N%N%Total623100.060697.3168279415.1CCI ScoreMean (SD)2.31 (1.85)2.39 (1.82)1.85 (1.47)2.57 (2.41)ComorbiditiesTotal Patients57191.7%48680.2%13077.4%7680.9%Asthma17029.8%12525.7%3325.4%2532.9%Chronic Kidney Disease478.2%326.6%75.4%810.5%COPD13824.2%10822.2%2216.9%1621.1%Cardiovascular disease35762.5%27857.2%6146.9%5572.4%Hypertension44778.3%37176.3%8766.9%6382.9%Hyperlipidemia41873.2%35072.0%6650.8%4761.8%Malignancy12421.7%10120.8%1813.9%2026.3%Peripheral artery disease7413%5811.9%107.7%1114.5%T2DM31855.7%25151.7%5844.6%3748.7%Note: Comorbidities and CCI was calculated for patients during follow-up in respective cohortConclusion:Puerto Rican patients with RA have a significant burden of comorbidities, infections and hospitalisations.

Abstract
AIMS To determine the incidence rates of cardiovascular disease (CVD) and assess the effect of metabolic risk factor management on the development of CVD in patients with diabetes. METHODS We studied 733 patients with diabetes without prior CVD in the Shanghai Taopu community health service center. Success in managing CVD risk factors was evaluated as follows: (1) glucose control (haemoglobin A1c [HbA1c] <7.0% in patients aged <65years and <8.0% in patients aged ≥65years), (2) blood pressure control (<140/90mmHg), and (3) lipid control (high-density lipoprotein cholesterol ≥1.0mmol/L in men and ≥1.3mmol/L in women, and triglycerides <1.7mmol/L). RESULTS During a median 8.0-year follow-up, 206 CVD incident cases were identified. Each 1% increment in HbA1c, 10mmHg increment in systolic blood pressure (SBP), and 1mmol/L increment in triglycerides during follow-up significantly increased the risk of CVD by 17%, 37%, and 14%, respectively. Compared to those who did not, patients who met the blood pressure and glucose control goals during follow-up had a 64% and a 29% decreased risk of CVD, respectively. The multivariable-adjusted hazard ratios of CVD were 1.00, 1.78 (95% confidence interval [CI] 1.10-2.87), and 2.51 (95% CI 1.54-4.07) among patients who attained three, two, and one/none of the CVD factor control goals (HbA1c, blood pressure, and lipid) during follow-up, respectively. CONCLUSIONS Average levels of HbA1c, SBP, and triglycerides during follow-up were positively associated with the risk of CVD, and treatment targeting multiple factors can significantly reduce CVD risk.

Abstract
Background:Limited information is available on the impact of target disease-modifying anti-rheumatic drugs (tDMARD) on patients with rheumatoid arthritis (RA) and type 2 diabetes mellitus (T2DM).Objectives:The objective was to compare T2DM-related healthcare resource utilization (HCRU) and cost for TNF inhibitors (TNFi)-naive patients pooled from two commercial databases with RA and T2DM receiving abatacept, other non-TNFi, or TNFi.Methods:A retrospective, observational study was conducted with MarketScan and PharMetrics (January 2008-September 2018). The study population included TNFi-naïve adult patients with RA and T2DM newly initiating abatacept, TNFi (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab) or other non-TNFi (tocilizumab, anakinra, sarilumab, rituximab, tofacitinib). Date of tDMARD initiation was the index date. Patients had ≥2 RA diagnoses separated by ≥7 days, ≥1 T2DM diagnosis, and had ≥12 months of pre-index continuous enrollment. Follow-up ended at the end of patient insurance enrollment, study period or index treatment. T2DM-related HCRU and costs including inpatient stay, outpatient visits, ER visits, and pharmacy use were measured on a per-patient-per-month (PPPM) basis (2018 USD). Patients treated with abatacept were matched to TNFi and non-TNFi cohorts separately by propensity score adjusted with patients baseline comorbidities, HCRU, and costs.Results:A total of 16,236 patients meeting criteria were identified. Most patients were female (74.3%), and the overall average age of 55.4 years (Table 1). After matching, 850 pairs of abatacept vs non-TNFi patients, and 1,096 pairs of abatacept vs TNFi patients were included in the adjusted results. Patients initiating abatacept had $144 lower adjusted T2DM-related costs as compared to non-TNFi and $79 lower costs than TNFi cohorts (Table 2).Table 1.Patient CharacteristicsAbataceptn=1,134Non-TNFin=1,353TNFin=13,749TotalN=16,236Age, mean years (SD)58.5 (11.3)57.7 (11.2)54.9 (10.6)55.41 (10.7)Gender, female, n (%)936 (82.5)993 (73.4)10,142 (73.8)12,071 (74.3)CCI, mean (SD)2.2 (1.4)2.3 (1.4)1.8 (1.1)1.89 (1.14)DCSI, n (%) Cardiovascular361 (31.8)406 (30.0)2,500 (18.2)3,267 (20.1) Neuropathy294 (25.9)374 (27.6)3,161 (23.0)3,829 (23.6) Nephropathy146 (12.9)193 (14.3)1,151 (8.4)1,490 (9.2) PVD131 (11.6)155 (11.5)874 (6.4)1,160 (7.1) Retinopathy103 (9.1)119 (8.8)922 (6.7)1,144 (7.0) Cerebrovascular74 (6.5)102 (7.5)620 (4.5)796 (4.9) Metabolic9 (0.8)20 (1.5)141 (1.0)170 (1.0)CCI: Charlson comorbidity index; DCSI: diabetes complications severity index; PVD: peripheral vascular disease.Table 2.Adjusted T2DM-related HCRU and Costs after Propensity Score MatchingAbataceptn=850Non-TNFin=850Diff (ABA- Non-TNF)Abataceptn=1,096TNFin=1,096Diff (ABA- TNF)T2DM-related HCRU (per 1000 Patients per Month)Number of Hospitalizations13.920.4-6.5*12.614.9-2.3*Number ofER Visits22.016.15.9*18.416.32.0*Number ofOutpatient Visits311334.8-23.7*299.3286.912.4T2DM-related Costs (PPPM $)Inpatient Costs507535-28413475-62ER Costs271710*2225-3Outpatient Costs190323-13318617016*Pharmacy Costs1071007*97128-31Total Costs831975-144719798-79**P<0.05Conclusion:TNFi-naive RA patients with T2DM newly initiating abatacept had lower adjusted rates of T2DM-related hospitalizations compared to patients who initiated a non-TNFi or a TNFi. Total costs were lower among patients initiating abatacept vs. patients who initiated a non-TNFi or a TNFi. Findings suggest that initial abatacept among TNFi-naïve patients may be able to reduce healthcare utilization arising from T2DM complications and reduce T2DM-related costs in RA patients.Disclosure of Interests:Xue Han Employee of: BMS, Qian Xia Shareholder of: I own shares of Bristol-Myers Squibb Company, Employee of: I am a paid employee of Bristol-Myers Squibb Company, Ying Bao Shareholder of: Bristol-Myers Squibb, Employee of: Bristol-Myers Squibb, Vardhaman PATEL Employee of: Bristol Myers Squibb, Amrina Roy Employee of: Mu-Sigma, Varshini Rajagopalan Employee of: Mu-Sigma, Francis Lobo Shareholder of: Bristol-Myers Squibb (US), Employee of: Bristol-Myers Squibb (US)

Abstract
Background:Studies have reported the association between overweight or obesity and ankylosing spondylitis (AS), but their relation is still unclear in China.Objectives:To explore the prevalence of overweight or obesity and its effect on other indicators and their relationships in Chinese AS patients.Methods:Demographic and clinical variables were collected from 207 AS patients. Patients were categorized to normal BMI group (BMI < 23kg/m2) and overweight group (BMI ≥ 23kg/m2). We used Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Metrology Index (BASMI), Health Assessment Questionnaire (HAQ), Ankylosing Spondylitis Quality of Life (ASQoL) and Medical Outcomes Study Short Form 36 (SF-36) to evaluate disease activity, physical function, spinal mobility, functional limitation and health-related quality of life, respectively. Statistical analysis used independent t test, Mann-Whitney U test, Chi-square test and Spearman’s rank correlation test.Results:56.5% (117) AS patients were overweight or obese, among which 80.3% (94) were male. In the overweight group, patients were older, more being married, and have higher BMI, higher waist circumference, higher waist-to-hip ratio, longer disease duration, higher BASMI score, higher white blood cell count (WBC), higher lymphocyte and higher platelet count compared to the non-overweight group (P≤ 0.038). However, there was no distinct difference in BASDAI score between the two groups (P= 0.891). In the correlation analyses, gender and marital status (P≤ 0.036) were correlated negatively with BMI; while age, waist circumference, waist-to-hip ratio, WBC, lymphocyte count and red blood cell (P≤ 0.036) were correlated positively with BMI.Conclusion:Overweight or obesity is common in Chinese AS patients. Increased BMI affects not disease activity but spinal mobility, which indicates that patients with high BMI are more likely to have limitations in flexion, extension, lateral bending and torsion of spine.References:[1]Bowness P.

Abstract
INTRODUCTION Cancer patients receiving chemotherapy are a high risk of VTE, yet the importance of thromboprophylaxis for cancer patients that are at high risk of developing VTE is still controversial. AIM To calculate the benefits and harms of thromboprophylaxis, compared to placebo, in ambulatory high-risk cancer patients that are receiving chemotherapy. METHODS We searched PubMed, Embase, Web of Science, the Cochrane Library, Cochrane Central Register of Controlled Trials, Chinese Biomedical Literature Database, WANFANG Data, Chinese National Knowledge Infrastructure and Chinese Scientific Journal Database for randomized controlled trials (RCTs) describing benefits and harms of thromboprophylaxis. Statistical analysis was performed using Stata software (version 15.1). RESULTS We included six studies, which contained a total of 3240 cancer patients with thromboprophylaxis and 2874 cancer patients without thromboprophylaxis. Thromboprophylaxis was effective in high-risk patients with two points or higher (RR 0.51, 95% CI 0.36-0.71, I2 = 0.0%, P = 0.526). It was associated with an increase in bleeding events (RR 1.65, 95% CI 1.14-2.40, I2 = 0.0%, P = 0.498) and was mainly efficient in reducing the risk of pulmonary embolism (RR 0.56, 95% CI 0.33-0.96, I2 = 0.0%, P = 0.263). The risk of major (RR 1.85, 95% CI 0.87-3.94, I2 = 0.0%, P = 0.888) and non-major (RR 1.59, 95% CI 0.96-2.62, I2 = 16.3%, P = 0.303) bleeding showed no significant difference with or without thromboprophylaxis. There was no reduction in all-cause mortality with thromboprophylaxis (RR 0.95, 95% CI 0.78-1.18, I2 = 22.0%, P = 0.277). CONCLUSION Thromoboprophylaxis is effective and safe in cancer patients that are at high risk for developing VTE with chemotherapy.

Inhibition of miR-103a-3p suppresses the proliferation in oral squamous cell carcinoma cells via targeting RCAN1. Neoplasma 2020; 67:461-472.

Abstract
Oral cancer is one of the common cancers worldwide, among which over 90% are oral squamous cell carcinomas (OSCC). MicroRNAs act as critical regulators of cancer development and progression. MiR-103a-3p has been reported to be upregulated in OSCC patients and closely correlated to poor prognosis, yet its roles in the progression of OSCC remain undisclosed. In this study, we knocked down the expression of miR-103a-3p in two OSCC cell lines in vitro, and significantly repressed cell proliferation and cell cycle arrest at the G1 phase were observed, accompanied by decreased proliferating cell nuclear antigen, cyclin D1, cyclin B1 and increased PTEN levels. MiR-103a-3p inhibition also induced apoptosis as evidenced by increased apoptotic cells and upregulated cleaved caspase-9/casapase-3 expression. We established a xenograft model in nude mice and found that miR-103a-3p knockdown also suppressed tumor growth in vivo. Besides, the expression of regulator of calcineurin1 (RCAN1), known as its anti-tumor effect, was negatively correlated with the miR-103a-3p level in OSCC cells. We validated that RCAN1 was a downstream target of miR-103a-3p using the dual-luciferase assay. RCAN1 silencing reversed the cell proliferative inhibition, cell cycle arrest and cell apoptosis induced by miR-103a-3p knockdown. In addition, we found that long non-coding RNA LINC00675 acted as a sponge of miR-103a-3p and promoted the expression of miR-103a-3p targets RCAN1 and PTEN. In summary, miR-103a-3p inhibition represses proliferation and induces apoptosis of OSCC cells through regulating RCAN1, and miR-103a-3p may act as a novel diagnostic marker and therapeutic target for OSCC.
