Abstract
In this work, the effect of alkaline earth metal modification on the catalytic performance of activated carbon supported Cu was investigated. The experimental results showed that the introduction of Ca and Sr improved the selectivity of methyl glycolate (MG) during hydrogenation of dimethyl oxalate (DMO) in gas phase. The optimal loading amount of Ca was 0.1 wt%, and under the optimal conditions (temperature 240 °C, pressure 2 MPa, hydrogen-ester ratio of 80, feedstock 15% DMO methanol solution, and WLHSVDMO = 0.9 h-1) the selectivity of MG was as high as 94%, and the conversion of DMO was 97%. The optimal loading of Sr was 0.2 wt% with MG selectivity up to 89% and DMO conversion of 98%. The results of catalyst characterization showed that both Ca and Sr modifications were beneficial to further reduce the particle size of Cu, improve the dispersion of Cu, increase the basicity of the catalyst, and improve the stable presence of Cu+ during the reaction process. Cu+ was beneficial to the stabilization of the MG species, in which Cu+ accounted for more in the Ca-modified catalysts Cu+/(Cu+ + Cu0) = 0.65, and in the Sr-modified ones Cu+/(Cu+ + Cu0) = 0.51. Therefore, both Ca and Sr modified catalysts showed improvement in the selectivity of MG.

Abstract
In order to prepare polyimide (PI) films with a low dielectric constant and excellent comprehensive performance, a two-step method was employed in this study to integrate β-cyclodextrin into a semi-aromatic fluorine-containing polyimide ternary system. By introducing trifluoromethyl groups to reduce the dielectric constant, the dielectric constant was further reduced to 2.55 at 10 MHz. Simultaneously, the film exhibited noteworthy thermal stability (a glass transition temperature exceeding 300 °C) and a high coefficient of thermal expansion. The material also demonstrated outstanding mechanical properties, boasting a strength of 122 MPa and a modulus of 2.2 GPa, along with high optical transparency (transmittance reaching up to 89% at 450 nm). Moreover, the inherent high transparency of colorless polyimide (CPI) combined with good stretchability contributed to the attainment of a low dielectric constant. This strategic approach not only opens up new opportunities for novel electroactive polymers but also holds potential applications in flexible displays, circuit printing, and chip packaging.

Abstract
BACKGROUND This study aimed to evaluate the efficacy and safety of intrathecal pemetrexed (IP) for treating patients with leptomeningeal metastases (LM) from non-small-cell lung cancer (NSCLC) who progressed from epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) treatment in an expanded, prospective, single-arm, phase II clinical study (ChiCTR1800016615). PATIENTS AND METHODS Patients with confirmed NSCLC-LM who progressed from TKI received IP (50 mg, day 1/day 5 for 1 week, then every 3 weeks for four cycles, and then once monthly) until disease progression or intolerance. Objectives were to assess overall survival (OS), response rate, and safety. Measurable lesions were assessed by investigator according to RECIST version 1.1. LM were assessed according to the Response Assessment in Neuro-Oncology (RANO) criteria. RESULTS The study included 132 patients; 68% were female and median age was 52 years (31-74 years). The median OS was 12 months (95% confidence interval 10.4-13.6 months), RANO-assessed response rate was 80.3% (106/132), and the most common adverse event was myelosuppression (n = 42; 31.8%), which reversed after symptomatic treatment. The results of subgroup analysis showed that absence of brain parenchymal metastasis, good Eastern Cooperative Oncology Group score, good response to IP treatment, negative cytology after treatment, and patients without neck/back pain/difficult defecation had longer survival. Gender, age, previous intrathecal methotrexate/cytarabine, and whole-brain radiotherapy had no significant influence on OS. CONCLUSIONS This study further showed that IP is an effective and safe treatment method for the EGFR-TKI-failed NSCLC-LM, and should be recommended for these patients in clinical practice and guidelines.

Abstract
BACKGROUND Checkpoint inhibitors have shown improvement in recurrence-free survival in the post-operative setting for node-positive melanoma and were first approved in late 2015. However, single-agent checkpoint therapies have yet to show benefit to overall survival (OS) for lower-risk stage III cancers. We evaluated the OS benefit of post-operative immunotherapy in the National Cancer Database (NCDB). PATIENTS AND METHODS Patient cases were selected from the NCDB 2020 Participant Use File. Patients diagnosed with stage III cutaneous melanoma between 2016 and 2019 who underwent definitive resection for their melanoma were included. OS between those who received post-operative immunotherapy within 84 days of surgery and those who did not was analyzed by the Kaplan-Meier method. Demographic and clinical characteristics between the two groups were compared via Cox proportional hazard models. RESULTS 14 978 patients with stage III melanoma were included. Of those, 34.9% (n = 5234) received post-operative immunotherapy and 65.1% (n = 9744) did not. Using the American Joint Committee on Cancer version 8 (AJCCv8) staging, 36-month survival was significantly higher in patients who received post-operative immunotherapy compared to no post-operative systemic therapy in those diagnosed with stage IIIB (88.0% versus 84.7%, P = 0.011), IIIC (75.6% versus 68.1%, P < 0.001), or IIID (59.2% versus 48.4%, P = 0.002). No significant improvement in 36-month survival was seen in patients who received post-operative immunotherapy in patients with stage IIIA disease (93.0% versus 92.2%, P = 0.218). CONCLUSIONS Post-operative immunotherapy had an OS benefit in patients with AJCCv8 stage IIIB, IIIC, and IIID disease, but had no significant survival benefit for patients with stage IIIA melanomas.

Abstract
PURPOSE/OBJECTIVE(S) Organ motion is challenging during primary definitive external beam radiotherapy in locally advanced cervical cancer (LACC). Our study evaluated the manual adaptive planning approach three weeks after the treatment started, compared the dosimetric consequences of the manual adaptive plans to the scheduled plans, and explored the clinical factors predicting patients suitable for this replanning strategy. MATERIALS/METHODS We analyzed 82 patients receiving primary definitive external beam radiotherapy with weekly online cone-beam computed tomography (CBCT)-based monitoring. The re-CT simulation was performed during treatment to develop a new plan (manual adaptive plan) due to a significant deviation of the clinical target volume (CTV). To evaluate the dosimetric benefit, D98, homogeneity index (HI) and conformity index (CI) for the planning target volume (PTV), as well as D2cc of the bowel, bladder, sigmoid and rectum were compared between the manual adaptive plans and the scheduled ones. The clinical factors influencing target motion throughout treatment were analyzed by chi-square test and logistic regression analysis. RESULTS The re-CT simulation was performed after 15 fractions during treatment to develop the manual adaptive plan in 41 patients. The median CI and HI of the manual adaptive plan were significantly superior to the scheduled one (P = 0.001, 0.003, respectively), demonstrating a better dose coverage of the target volume. Compared to the scheduled plans, D98 of the manual adaptive plans increased by 3.3% (P = 0.0002), the average of D2cc to the rectum, bladder decreased 0.267Gy (P = 0.0049) and 0.321Gy (P = 0.0146), respectively. In addition, the chi-square test demonstrated that age (P = 0.024), primary tumor volume (P = 0.015), and parametrial infiltration (P = 0.022) were the clinical factors influencing target motion throughout treatment. Multivariate analysis further identified the large tumor volume (≥50cm3, OR = 3.254, P = 0.039) and parametrial infiltration (OR = 3.376, P = 0.018) as the independent risk factors. CONCLUSION We found the most significant organ motion happened after 15 fractions during treatment. The manual adaptive planning of definitive radiotherapy improved the dose coverage and decreased the volume of organs at risk of receiving clinically significant doses of RT in patients with LACC. Patients with bulky mass or with parametrial infiltration were highly suggested to receive manual adaptive planning after 15 fractions during definitive radiotherapy, a timesaving strategy compared to the daily online adaptive radiotherapy without compromising the target dose coverage.

Abstract
PURPOSE Plexiform neurofibromas (PNF) are peripheral nerve sheath tumors that cause significant morbidity in persons with neurofibromatosis type 1 (NF1), yet treatment options remain limited. To identify novel therapeutic targets for PNF, we applied an integrated multi-omic approach to quantitatively profile kinome enrichment in a mouse model that has predicted therapeutic responses in clinical trials for NF1-associated PNF with high fidelity. EXPERIMENTAL DESIGN Utilizing RNA sequencing combined with chemical proteomic profiling of the functionally enriched kinome using multiplexed inhibitor beads coupled with mass spectrometry, we identified molecular signatures predictive of response to CDK4/6 and RAS/MAPK pathway inhibition in PNF. Informed by these results, we evaluated the efficacy of the CDK4/6 inhibitor, abemaciclib, and the ERK1/2 inhibitor, LY3214996, alone and in combination in reducing PNF tumor burden in Nf1flox/flox;PostnCre mice. RESULTS Converging signatures of CDK4/6 and RAS/MAPK pathway activation were identified within the transcriptome and kinome that were conserved in both murine and human PNF. We observed robust additivity of the CDK4/6 inhibitor, abemaciclib, in combination with the ERK1/2 inhibitor, LY3214996, in murine and human NF1(Nf1) mutant Schwann cells. Consistent with these findings, the combination of abemaciclib (CDK4/6i) and LY3214996 (ERK1/2i) synergized to suppress molecular signatures of MAPK activation and exhibited enhanced antitumor activity in Nf1flox/flox;PostnCre mice in vivo. CONCLUSIONS These findings provide rationale for the clinical translation of CDK4/6 inhibitors alone and in combination with therapies targeting the RAS/MAPK pathway for the treatment of PNF and other peripheral nerve sheath tumors in persons with NF1.

Abstract
Objective: To methodically assess the clinical effectiveness and safety of robot-assisted total rectal mesenteric resection (RTME), laparoscopic-assisted total rectal mesenteric resection (laTME), and transanal total rectal mesenteric resection (taTME). Methods: A computer search was conducted on PubMed, Embase, Cochrane Library, and Ovid databases to identify English-language reports published between January 2017 and January 2022 that compared the clinical efficacy of the three surgical procedures of RTME, laTME, and taTME. The quality of the studies was evaluated using the NOS and JADAD scales for retrospective cohort studies and randomized controlled trials, respectively. Direct meta-analysis and reticulated meta-analysis were performed using Review Manager software and R software, respectively. Results: Twenty-nine publications comprising 8,339 patients with rectal cancer were ultimately included. The direct meta-analysis indicated that the length of hospital stay was longer after RTME than after taTME, whereas according to the reticulated meta-analysis the length of hospital stay was shorter after taTME than after laTME (MD=-0.86, 95%CI: -1.70 to -0.096, P=0.036). Moreover, the incidence of anastomotic leak was lower after taTME than after RTME (OR=0.60, 95%CI: 0.39 to 0.91, P=0.018). The incidence of intestinal obstruction was also lower after taTME than after RTME (OR=0.55, 95%CI: 0.31 to 0.94, P=0.037). All of these differences were statistically significant (all P<0.05). There were no statistically significant differences between the three surgical procedures regarding the number of lymph nodes cleared, length of the inferior rectal margin, or rate of positive circumferential margins (all P>0.05). An inconsistency test using nodal analysis revealed no statistically significant differences between the results of direct and indirect comparisons of the six outcome indicators (all P>0.05). Furthermore, we detected no significant overall inconsistency between direct and indirect evidence. Conclusion: taTME has advantages over RTME and laTME, in terms of radical and surgical short-term outcomes in patients with rectal cancer.

Abstract
OBJECTIVE To explore the biomarkers of tinnitus in vestibular schwannoma patients using electroencephalographic (EEG) microstate technology. METHODS The EEG and clinical data of 41 patients with vestibular schwannoma were collected. All the patients were evaluated by SAS, SDS, THI and VAS scales. The EEG acquisition time was 10-15 min, and the EEG data were preprocessed and analyzed using MATLAB and EEGLAB software package. RESULTS Of the 41 patients with vestibular schwannoma, 29 patients had tinnitus and 12 did not have tinnitus, and their clinical parameters were comparable. The average global explanation variances of the non-tinnitus and tinnitus groups were 78.8% and 80.1%, respectively. The results of EEG microstate analysis showed that compared with those without tinnitus, the patients with tinnitus had an increased frequency (P=0.033) and contribution (P=0.028) of microstate C. Correlation analysis showed that THI scale scores of the patients were negatively correlated with the duration of microstate A (R=-0.435, P=0.018) and positively with the frequencies of microstate B (R=0.456, P=0.013) and microstate C (R=0.412, P=0.026). Syntax analysis showed that the probability of transition from microstate C to microstate B increased significantly in vestibular schwannoma patients with tinnitus (P=0.031). CONCLUSION EEG microstate features differ significantly between vestibular schwannoma patients with and without tinnitus. This abnormality in patients with tinnitus may reflect the potential abnormality in the allocation of neural resources and the transition of brain functional activity.

Abstract
OBJECTIVE Animal studies and clinical trials demonstrated the effectiveness of a combination of transplanted bone marrow stromal cells (BMSC) and electroacupuncture (EA) treatment in improving neurological deficits. However, the ability of the BMSC-EA treatment to enhance brain repair processes or the neuronal plasticity of BMSC in ischemic stroke model is unclear. The purpose of this study was to investigate the neuroprotective effects and neuronal plasticity of BMSC transplantation combined with EA in ischemic stroke. MATERIALS AND METHODS A male Sprague-Dawley (SD) rat middle cerebral artery occlusion (MCAO) model was used. Intracerebral transplantation of BMSC, transfected with lentiviral vectors expressing green fluorescent protein (GFP), was performed using a stereotactic apparatus after modeling. MCAO rats were treated with BMSC injection alone or in combination with EA. After the treatment, proliferation and migration of BMSC were observed in different groups by fluorescence microscopy. Quantitative real-time PCR (qRT-PCR), Western blotting, and immunohistochemistry were performed to examine changes in the levels of neuron-specific enolase (NSE) and nestin in the injured striatum. RESULTS Epifluorescence microscopy revealed that most BMSC in the cerebrum were lysed; few transplanted BMSC survived, and some living cells migrated to areas around the lesion site. NSE was overexpressed in the striatum of MCAO rats, illustrating the neurological deficits caused by cerebral ischemia-reperfusion. The combination of BMSC transplantation and EA attenuated the expression of NSE, indicating nerve injury repair. Although the qRT-PCR results showed that BMSC-EA treatment elevated nestin RNA expression, less robust responses were observed in other tests. CONCLUSIONS Our results show that the combination treatment significantly improved restoration of neurological deficits in the animal stroke model. However, further studies are required to see if EA could promote the rapid differentiation of BMSC into neural stem cells in the short term.

Abstract
OBJECTIVE Studies of possible implications of the maternal hepatitis C virus (HCV) infection in terms of intrauterine fetal growth restriction (IUGR), preterm birth (PTB), low birth weight (LBW) infants, premature rupture of membranes (PROM), maternal and neonatal mortality are limited and inconclusive. Our study aims to assess the impact of HCV on maternal and neonatal outcomes. MATERIALS AND METHODS Systematic literature search was done in PubMed, Scopus, and Google Scholar, Cochrane Library, and TRIP databases for all observational studies published from 1st January 1950 to 15th October 2022. The pooled odds ratio (OR) or risk ratio (RR) with a 95% confidence interval (CI) was estimated. STATA version 12.0 software was used for analysis. Heterogeneity among the included articles was evaluated by sensitivity, meta-regression, and publication bias analyses. RESULTS A total of 14 studies involving 12,451 HCV (+) and 56,42,910 HCV (-) pregnant women were included in our meta-analysis. Maternal HCV during pregnancy was significantly associated with the increased risk of PTB (OR=1.66, 95% CI: 1.59-1.74), IUGR (OR=2.09, 95% CI: 2.04-2.14) and LBW (OR=1.96, 95% CI: 1.63-2.36) as compared to healthy pregnant women. Subgroup analysis based on ethnicity also suggested a strong association between maternal HCV infection and a higher risk of PTB in Asian and Caucasian populations. Maternal (RR=3.44, 95% CI: 1.85-6.41), as well as neonatal (RR=1.54, 95% CI: 1.18-2.02) mortality was significantly higher in HCV (+) cases. CONCLUSIONS Mothers with HCV infection had a markedly increased probability of PTB and/or IUGR and/or LBW. In clinical practice, standard care of treatment and proper monitoring are needed for the pregnant population with HCV infection. Our findings may provide useful information for selecting appropriate therapy methods for HCV-positive pregnant women.

Abstract
AIM To investigate the correlation between capsule endoscopy (CE) classification of primary intestinal lymphangiectasia (PIL) and computed tomography (CT) lymphangiography (CTL). MATERIALS AND METHODS A total of 52 patients with diagnosed PIL were enrolled. All patients were examined using CTL and small intestinal CE before surgery. CE assessments included the morphology, scope, colour, and size of lesions. CTL assessments included intestinal wall, lymphatic vessel dilatation, lymph fluid reflux, and lymphatic fistula. Patients were divided into three groups according to type diagnosed by CE, and the CTL characteristics were analysed among the groups. RESULTS CE showed 15 patients with type I, 27 with II, and 10 with type III. Intestinal wall thickening was observed in 15 type I, 21 type II, and seven type III. Pericardial effusion was observed in only three type I patients; the difference among types was statistically significant (p=0.02). Abnormal contrast agent distribution in the intestinal wall and mesentery was observed in 15 type II patients, and the difference was significantly greater than that of types I and III (p=0.02). Abnormal contrast agent distribution in the abdominal cavity was observed in 12 type II, and the difference was statistically significant (p=0.03). CONCLUSION The CE PIL classification reflects the extent and scope of intestinal mucosa lesions; CTL more systematically demonstrates abnormal lymphatic vessels or reflux, and its manifestations of PIL are related to the CE classification. The combination of CTL with CE is useful for accurately evaluating PIL, and provides guidance for preoperative assessment and treatment management of PIL patients.

Abstract
Lentils provide a rich plant-based protein source and staple food in many parts of the world. Despite numerous nutritional benefits, lentil seeds also possess undesirable elements, such as anti-nutritional factors. Understanding the genetic networks of seed metabolism is of great importance for improving the seed nutritional profile. We applied RNA sequencing analysis to survey the transcriptome of developing lentil seeds and compared this with that of the pod shells and leaves. In total, we identified 2622 genes differentially expressed among the tissues examined. Genes preferentially expressed in seeds were enriched in the Gene Ontology (GO) terms associated with development, nitrogen and carbon (N/C) metabolism and lipid synthesis. We further categorized seed preferentially expressed genes based on their involvement in storage protein production, starch accumulation, lipid and suberin metabolism, phytate, saponin and phenylpropanoid biosynthesis. The availability of transcript profile datasets on lentil seed metabolism and a roadmap of candidate genes presented here will be of great value for breeding strategies towards further improvement of lentil seed quality traits.

Abstract
Abstract
Funding Acknowledgements
Type of funding sources: None.
Background
The prevalence of Type-1 Brugada pattern in Caucasians and Asians have been estimated to be 20 and 180 per 100,000. However, the prevalence of Type-1 Brugada pattern in African Americans has never been studied.
Purpose
This study aims to identify the prevalence of Type-1 Brugada pattern in African Americans.
Methods
Medical records of African American patients ages 18 years old or older with at least one 12-lead electrocardiogram (ECG) performed at 16 hospitals from 5 states in a single healthcare system between January 1, 2011 to December 31, 2020 were included. The search engine software was used to identify patients with keywords (Brugada pattern, Brugada ECG, Brugada Type-1, or Brugada syndrome) documented in the electronic medical record. The 12-lead ECGs were retrospectively analyzed by 2 cardiologists. Any inconsistencies were reviewed by a third cardiac electrophysiologist. Type-1 Brugada pattern was diagnosed according to the recent Heart Rhythm Society Expert Consensus Statement.
Results
Among 43,116 African American patients, (46.9% males), 6 patients (mean age 44.8±13.9 years, 100% males) had Type-1 Brugada pattern documented on at least one 12-lead ECG. The prevalence of Type-1 Brugada pattern in this large patient population of African American was 13.9 per 100,000. None of the patients had major arrhythmic event at 6.7±4.7 years follow-up.
Conclusions
The prevalence of Type-1 Brugada pattern in African American is lower than Caucasian and Asian populations. The risk of major arrhythmic event of Type-1 Brugada pattern in African American appears to be low; however longer follow-up data is needed.

Abstract
UNLABELLED We examined serum IGF-1 in premenopausal IOP, finding relationships that were opposite to those expected: higher IGF-1 was associated with lower bone formation and higher body fat, and lower BMD response to teriparatide. These paradoxical relationships between serum IGF-1, bone, and fat may contribute to the mechanism of idiopathic osteoporosis in premenopausal women. INTRODUCTION Premenopausal women with idiopathic osteoporosis (IOP) have marked deficits in bone microarchitecture but variable bone remodeling. We previously reported that those with low tissue-level bone formation rate (BFR) are less responsive to teriparatide and have higher serum IGF-1, a hormone anabolic for osteoblasts and other tissues. The IGF-1 data were unexpected because IGF-1 is low in other forms of low turnover osteoporosis-leading us to hypothesize that IGF-1 relationships are paradoxical in IOP. This study aimed to determine whether IOP women with low BFR have higher IGF-1 and paradoxical IGF-1 relationships in skeletal and non-skeletal tissues, and whether IGF-1 and the related measures predict teriparatide response. METHODS This research is an ancillary study to a 24 month clinical trial of teriparatide for IOP. Baseline assessments were related to trial outcomes: BMD, bone remodeling. SUBJECTS Premenopausal women with IOP(n = 34); bone remodeling status was defined by baseline cancellous BFR/BS on bone biopsy. MEASURES Serum IGF-1 parameters, compartmental adiposity (DXA, CT, MRI), serum hormones, and cardiovascular-risk-markers related to fat distribution. RESULTS As seen in other populations, lower BFR was associated with higher body fat and poorer teriparatide response. However, in contrast to observations in other populations, low BFR, higher body fat, and poorer teriparatide response were all related to higher IGF-1: IGF-1 Z-score was inversely related to BFR at all bone surfaces (r = - 0.39 to - 0.46; p < 0.05), directly related to central fat (p = 0.05) and leptin (p = 0.03). IGF-1 inversely related to 24 month hip BMD %change (r = - 0.46; p = 0.01). CONCLUSIONS Paradoxical IGF-1 relationships suggest that abnormal or atypical regulation of bone and fat may contribute to osteoporosis mechanisms in premenopausal IOP.

Abstract
Aims This study aims to investigate the potential application of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to predict concurrent chemoradiation (CRT) in locally advanced esophageal carcinoma. Patients and Methods This study involved 33 patients with locally advanced esophageal cancer and treated with CRT. The patients underwent DCE-MRI before CRT (pre) and 3 weeks after starting CRT (mid). The patients were categorized into two groups: complete response (CR) and non-complete response (non-CR) after 3 months of treatment. The quantitative parameters of DCE-MRI (Ktrans, Kep, and Ve), the changes and ratios of parameters (ΔKtrans, ΔKep, ΔVe, rΔKtrans, rΔKep, and rΔVe), and the relative ratio in the tumor area and a normal tube wall (rKtrans, rKep, and rVe) were calculated and compared between two timeframes in two groups, respectively. Moreover, the receiver operating characteristics (ROC) statistical analysis was used to assess the above parameters. Results We divided 33 patients into two groups: 22 in the CR group and 11 in the non-CR group. During the mid-CRT phase in the CR group, both Ktrans and Kep rapidly decreased, while only Kep decreased in the non-CR group. The pre-Ktrans and pre-Kep in the CR group were substantially higher compared to the non-CR group. Moreover, the rKtrans was also apparently observed as higher at pre-CRT in the CR group compared to the non-CR group. The ROC analysis demonstrated that the pre-Ktrans could be the best parameter to evaluate the treatment performance (AUC = 0.74). Conclusion Pre-Ktrans could be a promising parameter to forecast how patients with locally advanced esophageal cancer will respond to CRT.

Abstract
Given the growing rate of Gram-negative bacterial infections, antibiotics are now frequently prescribed for various respiratory diseases. Doxofylline is a newer generation xanthine with both bronchodilating and anti-inflammatory activities, but its influence on antibiotics remains poorly understood. Here, we first report the discovery of doxofylline-induced high minimum inhibitory concentrations of antibiotics. We also showed that doxofylline blocked antimicrobial-mediated killing for Gram-negative pathogens in vitro and in murine lung infection models in vivo. By combining efflux pump inhibition tests, gene expression analyses, and using the gene tolC knockout strain, we found that doxofylline positively regulated gene expression of the AcrAB-TolC efflux pump and attenuated the effect of doxofylline on antibacterial activities in ΔtolC mutants. Notably, doxofylline-mediated protection correlated with decreased reactive oxygen species (ROS) production. Collectively, our study indicates that doxofylline protects Gram-negative bacteria from antimicrobial lethality by regulating the AcrAB-TolC efflux pump in a TolC-dependent manner and suppressing antibiotic-induced ROS accumulation. These results suggest caution when using antibiotics alongside doxofylline in clinical treatment.

Abstract
Abstract
Phosphoinositide 3-kinase alpha (PI3Kα) H1047R mutations are activating oncogenic events that occur in ~15% of advanced breast cancers. While there is one PI3Kα inhibitor FDA-approved for patients with PI3Kα-mutated breast cancer, and many others in clinical development, all of these agents inhibit wild-type PI3Kα and its mutated form with approximate equal potency. As a result, their efficacy is limited by toxicities associated with on target wild-type PI3Kα inhibition, notably hyperglycemia as well as cutaneous and GI toxicity. LOX-22783 is a highly potent, mutant-selective and brain-penetrant allosteric PI3Kα H1047R inhibitor. Here, we describe the preclinical profile of LOX-22783. H1047R selectivity was measured using biochemical kinase activity and cell-titer Glo and signal transduction assays. Tumor growth inhibition, pharmacokinetic and pharmacodynamic effects were assessed in in vivo studies using xenograft and patient-derived xenograft (PDX)-models. LOX-22783 inhibited growth and signaling responses in multiple H1047R-driven breast cancer cell lines and demonstrated high selectivity for H1047R mutated PI3Kα (EC50 values <5 nM) relative to wild-type PI3Kα (EC50 >250 nM) as well as the other wild-type PI3K isoforms (beta, gamma, and delta, all EC50 >250nM). In enzyme and cell-based assays, LOX-22783 dissociated from PI3Kα H1047R at a slower rate (3-6 hrs) compared to alpelisib (≤10 mins), potentially allowing for extended inhibition of PI3Kα H1047R by LOX-22783. LOX-22783 also normalized the EGF-stimulated membrane-localization of PI3Kα H1047R while alpelisib did not. LOX-22783 was highly kinome-selective when assayed at 3 µM, with no inhibitory activity on 17 lipid kinases or 374 protein kinases. In preclinical species, LOX-22783 demonstrated high oral bioavailability, including exposure in the CNS, a common site of metastases for patients with breast cancer. In vivo, LOX-22783 demonstrated dose-dependent tumor regression in H1047R breast cancer models without inducing hyperglycemia or other toxicities. Tumor pharmacodynamic analyses confirmed successful pathway inhibition. At doses resulting in 90% pathway inhibition, tumor regressions of ≥60% were observed. This wide therapeutic index is predicted to allow for maximizing dose intensity and efficacy in patients, without wild-type PI3Kα inhibition limiting target coverage for the H1047R mutant form. These data demonstrate that LOX-22783 potently and selectively inhibits mutant H1047R, but not wild-type PI3Kα, or other PI3K isoforms. LOX-22783 binds to an allosteric pocket distinct from the ATP binding site used by the approved and investigational PI3Kα inhibitors. We hypothesize that this profile will lead to differentiated efficacy and tolerability for patients with PI3Kα H1047R-mutated cancers, with the additional potential to address brain metastases. An IND submission is planned for 2022.

Abstract
Purpose Klebsiella pneumoniae-induced liver abscess (KLA) is a type of pyogenic liver abscess (PLA), which is a distinct invasive syndrome that has been increasingly reported worldwide over the past two decades. The intestinal microbiota is increasingly recognized as an important modulator that can promote and maintain host immune homeostasis. However, its precise role in liver abscess is unknown. We aimed to investigate the function of the gut microbiota in the host defense against K. pneumoniae infection. Methods We constructed C57BL/6J mice with KLA and analyzed the diversity and richness of the intestinal microflora by 16S rRNA sequencing. Next, to create a microbiota-depleted (MD) mouse model, we administered multiple broad-spectrum antibiotics and validated the model using 16S rRNA sequencing. At 48 h after K. pneumoniae infection, we assessed the general health condition, liver injury, bacterial loads, and inflammatory factor levels in MD+KLA mice. Additionally, fecal microbiota transplantation (FMT) was conducted in another group of MD+KLA mice prior to K. pneumoniae infection, and we assessed whether the transplantation changed the outcomes. Results The diversity of the intestinal flora was significantly changed in KLA mice compared to control mice, with a decrease in beneficial bacteria and an increase in harmful bacteria. The MD+KLA mice exhibited impaired antimicrobial capacity, reduced survival, increased inflammation and liver damage at 48 h after K. pneumoniae infection compared to the KLA mice. However, FMT normalized the inflammatory cytokine levels, reduced liver damage, and increased survival. Conclusion This study identified the gut microbiota as a protective factor against K. pneumoniae infection. The role of FMT in KLA should be investigated in future clinical studies.

Abstract
Objective: To investigate the effect and mechanism of PPAR-γ agonist Pioglitazone (PGZ) on the proliferation of malignant mesothelioma (MM) cells. Methods: In December 2019, MM cell lines MSTO-211H and NCI-H2452 were incubated with different final concentrations of PGZ (0, 10, 50, 100, 150, and 200 μmol/L) for different periods of time (24 h, 48 h, and 72 h) , and then the cell proliferation level was detected by CCK8 assay. After given various final concentration of PGZ (0, 10, 50, 100, 150, 200 μmol/L) the for 72 hours, the changes of number and morphology of MM cells were observed under an inverted microscope. The expressions of PPAR-γ and HMGB1 mRNA were determined by real-time fluorescence quantitative reverse transcription-polymerase chain reaction (qRT-PCR) after treatment of MM cells with PGZ of 0, 10, 50, 100 μmol/L for 72 h. The MM cells were treated with PGZ at concentration of 0, 100 μmol/L for 72 h, and the protein expressions of HMGB1 were examined using Western blotting and immunofluorescence; the protein expressions of Ki67 were assessed by immunohistochemistry. Results: The cell viability rate of MM cells was decreased after treated with PGZ (P<0.05) . Cell number in PGZ-treated group was significantly less than that in control group and morphology changes were observed under light microscope. QRT-PCR results revealed significantly increased PPAR-γ mRNA expression in the PGZ-treated group compared to the control group (P<0.05) . There was a significant decrease in the mRNA expression level of HMGB1 in the PGZ-treated group (100 μmol/L) as compared to the control group in MSTO-211H (P<0.05) ; however, the expression level of HMGB1 in NCI-H2452 was an increase or no significant differences (P>0.05) . Western blotting and immunofluorescence results showed that the protein expression of HMGB1 was reduced in the PGZ-treated group compared with the control group in MSTO-211H (P<0.05) , but the protein expression of that in NCI-H2452 was no significant differences (P>0.05) . Immunohistochemistry results showed increased expression of proliferation marker Ki-67. Conclusion: Pioglitazone suppresses the proliferation of MM cells through inhibition of HMGB1 by the activation of PPAR-γ.

Abstract
Abstract
Nearly 70% of newly diagnosed breast cancers are estrogen receptor alpha (ERα) positive, for which endocrine therapy is a primary treatment. However, approximately 40% of those patients on endocrine therapy develop resistance, which includes mutations in ERα (ESR1) that drive constitutive activation of the receptor. One approach to overcome this resistance is to develop a potent degrader and pure antagonist of the estrogen receptor, which can effectively suppress estrogen receptor signaling. Fulvestrant, a pure antagonist and selective estrogen receptor degrader (SERD) is approved for the treatment of HR+/HER2- metastatic breast cancer. However, fulvestrant is limited by poor pharmacokinetics properties, limited exposure and sub-optimal in vivo estrogen receptor degradation. Here we describe the preclinical profile of LY3484356, an oral SERD and pure estrogen receptor antagonist, with potent activity against the wild type and mutant estrogen receptor. LY3484356 has Ki values of 0.64 nM and 2.8 nM against wild type ERα and Y537S mutant ERα proteins, respectively. It is a potent and highly efficient degrader of wild type ERα and Y537N mutant ERα proteins in cells, with IC50 values 3.0 nM and 9.6 nM, respectively. LY3484356 is also a potent inhibitor of ERα-mediated transcription in vitro and in vivo. It inhibits cell proliferation in wild type ERα and ESR1 Y537N mutant breast cancer cell lines, with average IC50 values of 3 nM and 17 nM, respectively. In a panel of breast cancer cell lines, 11 out of 12 ER+ breast cancer cell lines were sensitive to LY3484356 (IC50 less than 100 nM), whereas all ER- cell lines tested were insensitive. LY3484356 has demonstrated sustained and prolonged target inhibition (>75% inhibition of PGR transcription up to 96h after last dose) in ESR1 wild type (MCF7) and ESR1 Y537S mutant (ST941/C) xenograft tumors. Consistent with its profile as a pure antagonist, immature rat studies demonstrated no significant effect on uterine wet weight. LY3484356 demonstrated significant tumor growth inhibition and tumor regressions in wild type ESR1 breast cancer xenograft models such as MCF7, T47D and ZR-75-1, as well as ESR1 mutant breast cancer PDX models. LY3484356 has shown synergy or additivity in combination with CDK4/6 inhibitor abemaciclib, mTOR inhibitor everolimus and PIK3CA inhibitor alpelisib in inhibiting cell proliferation in ER+ breast cancer cell lines in vitro and tumor growth inhibition in relevant xenograft or PDX models in vivo. The first-in-human Phase 1/2 clinical trial of LY3484356 (EMBER, ClinicalTrials.gov NCT04188548) is currently ongoing and a window-of-opportunity study evaluating the pharmacodynamic effects of LY3484356 in early stage breast cancer is expected to begin early 2021.

Abstract
OBJECTIVE The aim of the study was to clarify the therapeutic mechanism of Dexmedetomidine (DEX) on the chronic obstructive pulmonary disease (COPD) and its regulatory effect on long non-coding RNA (lncRNA) PACER. PATIENTS AND METHODS Serum level of PACER in COPD patients was detected by quantitative real-time polymerase chain reaction (qRT-PCR). The diagnostic potential of PACER in COPD was assessed by plotting ROC curves. The in vivo COPD model was generated in rats by cigarette smoking exposure. Primary rat alveolar epithelial cells were isolated, purified and cultured. After overexpression of PACER in primary rat alveolar epithelial cells, proliferative and migratory abilities were assessed by cell counting kit-8 (CCK-8) and transwell assay, respectively. Subsequently, we detected changes in PACER expression, viability and migratory potentials in primary rat alveolar epithelial cells harvested from control rats, and those harvested from COPD rats and induced with either DEX or not. Rescue experiments were conducted to uncover the involvement of PP2A in PACER-regulated cell phenotypes. RESULTS PACER was upregulated in serum of COPD patients, which was a potential biomarker for diagnosing COPD. Overexpression of PACER in primary rat alveolar epithelial cells enhanced proliferative and migratory abilities. Compared with primary rat alveolar epithelial cells harvested from control rats, proliferative and migratory abilities were stronger in those harvested from COPD rats and induced with either DEX or not. Notably, DEX induction decreased PACER expression, and proliferative and migratory abilities in primary rat alveolar epithelial cells harvested from COPD rats. Overexpression of PP2A could partially abolish the promotive effects of PACER on proliferative and migratory abilities in DEX-induced primary rat alveolar epithelial cells harvested from COPD rats. CONCLUSIONS PACER drives the proliferative and migratory abilities of alveolar epithelial cells through activating PP2A. Dexmedetomidine is conducive to COPD treatment by downregulating PACER.

Abstract
AIM To assess systematically the prognostic value of cardiac magnetic resonance imaging (CMRI) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). MATERIALS AND METHODS The full text of studies of the clinical efficacy of late gadolinium enhancement (LGE) in ARVC was retrieved in multiple databases. Stata 14 was adopted for meta-analysis and bias analysis. Heterogeneity was assessed with the I2 statistic. RESULTS After exclusions, 561 patients were included in five studies, and the eligibility criteria were met. The meta-analysis suggested that there was a significant difference between LGE positive and negative patients with ARVC in all-cause mortality (relative risk [RR] = 4.78, 95% confidence interval [CI] = 1.41, 16.23, p=0.012; p for heterogeneity = 0.692, I2 = 0%); major adverse cardiovascular events (MACE) (RR=2.48, 95% CI = 1.24, 4.96, p=0.010; p for heterogeneity = 0.596, I2 = 0%); ventricular tachycardia (RR=3.13, 95% CI = 1.69, 5.78, p<0.001; p for heterogeneity = 0.825, I2 = 0%); implanted cardiac defibrillators (RR=3.15, 95% CI = 1.69, 5.87], p<0.001; p for heterogeneity = 0.353, I2 = 9.4%). CONCLUSION LGE in ARVC patients is a predictor of all-cause mortality and MACE.

Abstract
OBJECTIVES Hypertension is a growing health concern in people living with HIV (PLWH). However, association between HIV infection and hypertension is equivocal. METHODS In all, 1472 PLWH and 2944 HIV-negative individuals frequency-matched by age and sex were derived from the baseline survey of Comparative HIV and Aging Research in Taizhou (CHART), China. Prehypertension was defined as systolic blood pressure (BP) of 120-139 mmHg and/or diastolic blood pressure of 80-89 mmHg. RESULTS Despite the fact that prevalence of hypertension was overall lower among PLWH than among HIV-negative people (21.1% vs. 29.1%, P < 0.001), it was similar at ages 18-29 (7.6% vs. 8.5%) and 30-44 years (17.1% vs. 18.5%) but significantly lower in PLWH at ages 45-59 (26.1% vs. 40.7%) and 60-75 years (37.1% vs. 57.3%). Prehypertension prevalence was consistently higher in PLWH across all age groups. In the model adjusting for traditional risk factors, HIV infection was associated with hypertension (adjusted odds ratio [aOR] = 1.27, 95% confidence interval: 1.04-1.55) and prehypertension (aOR = 1.77, 95% CI: 1.51-2.08), and attenuated after additional adjustment for abdominal obesity. Age-stratified analysis showed that these associations of HIV with hypertension were observed at ages 18-29 and 30-44 years and associations with prehypertension were observed at ages 18-29, 30-44 and 45-59 years only. Years since HIV diagnosis and stavudine use were the HIV-specific factors independently associated with hypertension or/and prehypertension. CONCLUSIONS HIV infection is independently associated with prehypertension and hypertension especially at younger ages, and this risk may increase as treatment becomes prolonged. Our findings reinforce the urgent necessity for active BP screening and control strategies be adopted for PLWH in China.

Abstract
PURPOSE Medulloblastoma (MB) is a malignant brain disease in young children. The overall survival of MB patients is disappointing due to absence of effective therapeutics and this could be attributed to the lack of molecular mechanism underlying MB. FHOD3 was an important gene during cardio-genesis and was reported to promote cell migration in cancer. However, its role in MB is not clear to date. METHODS RT-qPCR and IHC analysis were used to determine expression of FHOD3. Survival curve was drawn by K-M analysis. FHOD3 was knocked down by RNAi technology. The effects of FHOD3 on medulloblastoma cells were determined by CCK-8 assay, colony formation assay, transwell assay and FACs analysis. RESULTS FHOD3 expression increased by 1.5 fold in tumor tissues compared to the control and IHC analysis further confirmed strong expression of FHOD3 in medulloblastoma tissues. Then higher FHOD3 expression was associated with shorter survival time in MB patients (13.0 months versus 43.8 months). In medulloblastoma cells such as Daoy and D283med, FHOD3 also displayed abundant expression. When FHOD3 was knocked down, the ability of cell proliferation and colony formation was reduced over greatly. The capability of cell migration and invasion was also inhibited significantly. However, cell apoptotic rate increased significantly reversely. Mechanistically, the phosphorylation level of RhoA, ROCK1, and LIMK1 was decreased when FHOD3 was knocked down but increased reversely when FHOD3 was over-expressed in Daoy cells. CONCLUSIONS FHOD3 was associated with overall survival time in medulloblastoma patients and was essential to cell proliferation, growth and survival in medulloblastoma and might regulates activation of RhoA/ROCK1/LIMK1 signaling pathway.

Abstract
Objective The aim of this study was to investigate the antimicrobial resistance profiles and distribution of virulence-related genes (VRGs) among Shigella isolates in Anhui, China, and to identify the correlation between the VRGs and antimicrobial resistance. Materials and Methods A total of 525 non-duplicate Shigella isolates (449 S. flexneri, 68 S. sonnei, 3 S. boydii, and 5 S. dysenteriae) were collected in Anhui Province, China between September 2011 and September 2015. The antimicrobial resistance of the strains was determined by the agar dilution method according to CLSI guidelines. The presence of 16 VRGs, including ipaH, ipaA-D, ial, virB, virF, set, sen, icsA, icsB, sigA, sat, pic, and sepA, was evaluated using PCR amplification and sequencing. Results Shigella flexneri was the most abundant (85.5%), followed by S. sonnei (13.0%). The proportion of males with S. flexneri was higher than that of females (57% vs 43%; P<0.0001). The most common resistance pattern was the combination of ampicillin, nalidixic acid, and tetracycline for S. flexneri (90.2%) and S. sonnei (94.1%). Resistance to ciprofloxacin and levofloxacin was more common among S. flexneri than among S. sonnei (49.7% vs.19.1%, P<0.0001; 30.5% vs 10.3%, P=0.001, respectively). All the isolates were positive for the ipaH gene, while the set, sat, pic, and sepA genes were not detected among the S. sonnei isolates. Except for sigA and sen, resistance to chloramphenicol and ciprofloxacin was more common among VRG-positive S. flexneri than among VRG-negative S. flexneri (P<0.05). Furthermore, resistance to ceftriaxone and ceftazidime was more frequently detected among sat- and set-positive S. flexneri than among sat- and set-negative S. flexneri (P<0.05). However, gentamicin resistance was more prevalent among VRG-negative (ial, virF, set, sat, pic, and sepA) S. flexneri than among VRG-positive S. flexneri (P<0.05). Conclusion Shigella flexneri remains the predominant species in Anhui, China, and the resistance to fluoroquinolones was more widespread among S. flexneri than among S. sonnei. Shigella flexneri strains harboring specific VRGs were associated with antimicrobial resistance. To the best of our knowledge, this is the first report of the correlation between the VRGs and antimicrobial resistance in Anhui, China.

Abstract
Abstract
The combination of BRAF and MEK inhibitors have been clinically studied, and three different combinations (dabrafenib plus trametinib, vemurafenib plus cobimetinib and encorafenib plus binimetinib) are approved by the FDA for treatment of melanoma patients with BRAF V600E mutation. Published reports indicate that each combination has a different efficacy and toxicity profile. It is believed that the toxicity profile of some of these drugs is linked to their pharmacokinetic (PK) profile leading to prolonged pharmacodynamics (PD) or target inhibition. ERK inhibitors have been discovered recently to overcome the acquired resistance to BRAF plus MEK inhibitors in BRAF-mutant melanoma and for combination therapies in RAS/MAPK altered cancers including KRAS-mutant cancers. Several ERK inhibitors have entered clinical development as monotherapy or in combination. However, it is not clear what the minimum time on target is required for efficacy without causing significant toxicity, and whether that would differentiate the therapeutic index of one inhibitor from another. Therefore, we have conducted PK-PD-efficacy relationship studies of different MEK and ERK inhibitors with different PK profiles in mice in BRAF-mutant or KRAS-mutant xenograft models to determine the minimum time on target required for efficacy. We have tested the PK-PD-efficacy of MEK inhibitors trametinib and cobimetinib, as well as ERK inhibitors BVD-523, GDC-0994 and LY3214996 in BRAF V600E or KRAS mutant xenograft models including A375 BRAF V600E melanoma, Colo205 BRAF V600E colorectal carcinoma and HCT116 KRAS G13D colorectal carcinoma. Additionally, an infusion study with LY3214996 was conducted in rats implanted with HCT116 colorectal carcinoma tumors, where drug exposure was controlled for a specified time to get ≥50% pRSK1 inhibition. Our data suggests that ≥50% inhibition of pRSK1 for 8h is required for significant efficacy of ERK inhibitor LY3214996, which is similar to the data presented for GDC-0994 (Robarge K et al, Abstract number DDT02-03, AACR Annual Meeting 2014). Overall assessment of the data in different models suggested that ≥50% target inhibition for 8-16h is enough for significant tumor growth inhibition and regressions by an ERK inhibitor in BRAF-mutant or KRAS-mutant tumors without any obvious toxicity as measured by body weight loss or mortality. LY3214996 is in Phase 1 clinical development and the preliminary PK profile in patients looks as predicted from preclinical data. Therefore, we believe that the PK profile of LY3214996 offers flexibility with dose and schedule to balance efficacy and safety, and to achieve a better therapeutic index in combination therapy for RAS/MAPK pathway altered cancers.

Abstract
OBJECTIVE The objective of this study is to explore the biological roles of microRNA-101-5p (miR-101-5p) in the growth and metastasis of cervical cancer. PATIENTS AND METHODS The levels of miR-101-5p and chemokine (C-X-C motif) ligand 6 (CXCL6) in cervical cancer tissues and cells were detected using the quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) assay. The proliferation, colony formation, migration, and invasion assays were conducted using miR-101-5p transfected cervical cancer cell. The expression of CXCL6 was measured by the immunoblotting assay. Xenograft model was constructed to reveal the precise roles of miR-101-5p in the growth of cervical cancer cell in vivo. RESULTS MiR-101-5p was down-regulated in cervical cancer tissues when compared to the normal controls. The levels of miR-101-5p were higher in cervical cancer cells (SiHa, Caski, C-4-I, C-33 A) than that in the human cervical surface epithelial cell line, HcerEpic. Over-regulation of miR-101-5p inhibited the aggressiveness phenotypes of a cervical cancer cell in vitro. Furthermore, over-regulation of miR-101-5p reduced the tumor growth of cervical cancer cell in vivo. CXCL6 was the target protein of miR-101-5p in cervical cancer as demonstrated by luciferase reporter assay. The mRNA level of CXCL6 was negatively associated with the miR-101-5p level in cervical cancer tissue. Finally, the rescue experiments suggested that the inhibitory role of miR-101-5p was mediated by regulating the expression of CXCL6 in cervical cancer. CONCLUSIONS These findings indicated that the over-regulation of miR-101-5p suppressed the progression of cervical cancer by targeting CXCL6 and might function as a potential therapeutic target for cervical cancer.

Abstract
Background and Aims Postoperative nausea and vomiting (PONV), one of the common complications following strabismus surgery, would delay the ambulatory discharge time. The aim of this retrospective study was to determine the risk factors of PONV in patients undergoing ambulatory strabismus surgery under general anaesthesia, with the treatments of dexamethasone and 5-HT3 antagonist combination. Methods We reviewed 721 consecutive patients (12-60 years old) undergoing ambulatory strabismus surgery under general anaesthesia at an academic eye centre between December 2016 and January 2019. Patients received prophylactic treatment of dexamethasone and 5-HT3 antagonist combination during anaesthesia induction, and PONV was evaluated during the early recovery period before discharge. Results The dexamethasone and 5-HT3 antagonist combination effectively reduced the incidence of PONV (3.05%, 22/721), and the patients who experienced PONV had statistically prolonged phase II recovery time as compared those who did not (P = 0.006). The sum of the extraocular muscles manipulated and the use of nalbuphine (vs flurbiprofen axetil) were the independent risk factors for PONV (P < 0.05). Conclusion The sum of the extraocular muscles manipulated and the use of nalbuphine are potentially modifiable risk factors for PONV after strabismus surgery with the treatments of dexamethasone and 5-HT3 antagonist combination.
