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
Purpose To assess safety and ocular hypotensive efficacy of VVN539 ophthalmic solution in a first-in-human study. Design Multicenter, double-masked, randomized, vehicle-controlled, dose-response, parallel-comparison study. Participants Sixty-eight subjects with ocular hypertension (OHT) or open-angle glaucoma enrolled at 5 private practices. Methods After washout of ocular hypotensive medications as required, the subjects were randomized to receive either VVN539 ophthalmic solution 0.02%, 0.04%, or vehicle once-daily (QD) in the morning (5 days), once-daily in the evening (6 days) and then twice-daily (6 days). Main Outcome Measures Comparison of VVNM539 to its vehicle in mean intraocular pressure (IOP) at each diurnal time point (8:00am, 10:00am, and 4:00pm) at visit 4 (day 7), visit 5 (day 14), and visit 6 (day 21). Results Mean IOP decreased throughout dosing in the active groups to between 18 and 20 mmHg in both active groups, to between 22 to 23 mmHg in the vehicle group. VVN539 0.04% was statistically superior to vehicle at all 9 diurnal time points (QD AM, QD PM, and twice daily, P ≤ 0.0109). VVN539 0.02% was statistically superior to vehicle at only 6 of 9 diurnal time points (selected QD times and twice daily). The most common ocular treatment-emergent adverse event was conjunctival hyperemia (11 [47.8%], 10 [4.5%], and 1 [4.3%]), followed by ocular hyperemia (3 [13.0%], 5 [22.7%] and 0), respectively. There were no clinically significant changes of note in visual acuity, biomicroscopy, dilated ophthalmoscopy, blood chemistry, hematology, or cardiovascular measures. Conclusions In conclusion, the results of this initial phase II study indicate that VVN539 ophthalmic solution showed clinically and statistically significant ocular hypertensive activity and was relatively well tolerated for the treatment of subjects with primary open-angle glaucoma or OHT. Additional studies will be required for a more complete evaluation of the utility of VVN539 ophthalmic solution.

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
BACKGROUND This study aimed to investigate the clinicopathological features and prognostic indicators of primary pulmonary adenoid cystic carcinoma (PACC). METHODS Clinical data were collected from 64 primary PACC patients and analyzed retrospectively at the Tianjin Medical University General Hospital, the West China Hospital of Sichuan University, the First Affiliated Hospital of Guangxi Medical University, and the Bishan Hospital of Chongqing Medical University from January 2003 to August 2023. The 64 patients (28 males and 36 females) were aged from 20 to 73 years, with a median age of 49 years and an average age of 49.3 years. RESULTS Immunohistochemical staining showed that the tumors expressed CK7, S-100 protein, CK5/6, CD117, and p63. Seven patients underwent fluorescence in situ hybridization (FISH) testing and three were found to have myeloblastosis (MYB) gene translocation. In total, 53 patients underwent surgery, among whom 31 received only surgery and 22 received both surgery and postoperative chemoradiotherapy. In addition, 10 patients received chemoradiotherapy only, while one patient underwent treatment with traditional Chinese medicine. The overall survival rates in the first, third, and fifth years were 98.4%, 95.3%, and 87.5%, respectively. CONCLUSION Prognostic analysis revealed that age, tumor size, lymph node metastasis status, margin status, and choice of treatment modality significantly influenced the patients' prognosis.

Abstract
As a typical type of organic flocculant, chitosan is limited by its poor water solubility and narrow pH range application. Grafting modification can improve chitosan's solubility and availability through linking macromolecular chains with other types of water-soluble groups or functional side groups. In this study, dielectric barrier discharge (DBD) was used to active the surface of chitosan, then activated chitosan was polymerized with acrylamide to synthesize a chitosan-based flocculant, chitosan-acrylamide (CS-AM). During the synthesis of CS-AM, the optimal conditions were determined as follows: discharge time of 5 min, discharge power of 60 W, total monomer mass concentration of 80 g L-1, polymerization time of 3 h, polymerization temperature of 70 °C, and m(CS) : m(AM) ratio of 1 : 3. The structure and morphological characteristics of CS-AM were investigated and analyzed by Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), thermogravimetric (TG) analysis, scanning electron microscopy (SEM), X-ray diffraction (XRD) and N2 physical adsorption, respectively. The removal efficiency of kaolin suspension and CNTs suspension can reach up to 95.9% and 90.2% after flocculation of CS-AM. Furthermore, the zeta potential of the supernatant from the CS-AM treated kaolin suspension at different pH values was examined, and the flocculation mechanism of CS-AM was analyzed. This study provides new ideas for the preparation and development of modified chitosan and broadens its application in water treatment.

Abstract
The formal cyclization strategy was generally used to construct azepino[4,5-b]indole. Herein, we reported a novel and expeditious protocol for the synthesis of quaternary carbon azepino[4,5-b]indole via ring expansion of ammonium ylide, which was formed by the reaction of tetrahydro-β-carbolines with the diazo compound. The easily available substrates, mild reaction conditions, and broad functional tolerance rendered this method a practical strategy that may significantly afford an efficient method of scaffold hopping in drug discovery.

Abstract
BACKGROUNDS Solitary fibrous tumor of the pleura (SFTP) is a rare thoracic tumor and usually asymptomatic. Massive SFTP may affect adjacent organs and tissues including pulmonary vasculature, bronchus and heart. A thoracotomy for massive SFTP is necessary in severe case. Therefore, it is important for anesthesiologists to understand the condition of patients with massive SFTP and develop an appropriate anesthetic management strategy. A 76-year-old woman with massive SFTP presented to our clinical center and was evaluated as requiring thoracotomy. She received multidisciplinary cooperation treatment from the radiology, cardiac, thoracic surgery and anesthetic teams. The perioperative management of anesthesiologists played a crucial role in the great prognosis of this woman. CONCLUSIONS This case report demonstrates the importance of comprehensive and meticulous perioperative management and provides guidance to the multidisciplinary team on the potential risk and the rational treatment strategy of patients with massive SFTP during the perioperative period.

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.

Nevertheless, knowledge of its expression, functions and potential molecular mechanisms in non-small cell lung cancer (NSCLC) remains elusive. METHODS Differential expression of WT1 mRNA and protein between NSCLC and normal tissues were assessed by analyzing RNA-seq data from Oncomine and protein data from Human Protein Atlas, respectively. Subsequently, prognosis significance and immune cell infiltration were analyzed by Kaplan-Meier plotter and CIBERSORT. 60 pairs of local NSCLC tissues were involved to validate WT1 expression by quantitative PCR (qPCR) and Western blot. Moreover, Cell Counting Kit-8 (CCK-8), colony formation, transwell, dual luciferase reporter assays and in vivo xenograft tumour growth experiments were conducted to explore the function and mechanism of WT1 in NSCLC. RESULTS Our solid data indicated that WT1 was increased in NSCLC tissues and cell lines in comparison with their matched controls. In particular, its upregulation correlated with worse prognosis and immune infiltration of the patients. Functional assays demonstrated that knockdown of WT1 inhibited NSCLC malignancy, including inhibiting cell proliferation, survival and invasion. Further exploration discovered that microRNA-498-5p (miR-498-5p) was the upstream suppressor of WT1 by directly targeting the 3' untranslated region (UTR) of WT1 mRNA. Moreover, expression of miR-498-5p was notably decreased and inversely correlated with WT1 in NSCLC tissues. Finally, we proved that miR-498-5p was a potent tumour suppressor in NSCLC by suppressing cell proliferation, survival and invasion, while WT1 restoration could in turn disrupt this suppression both in vitro and in vivo. CONCLUSION The abnormal increase in WT1 contributes to the malignant properties of NSCLC cells, and miR-498-5p is a natural inhibitor of WT1. Our findings might facilitate the development of novel therapeutic strategies against NSCLC in the future.

Abstract
PURPOSE Histone deacetylase (HDAC) inhibition has been shown to induce pharmacologic "BRCAness" in cancer cells with proficient DNA repair activity. This provides a rationale for exploring combination treatments with HDAC and PARP inhibition in cancer types that are insensitive to single-agent PARP inhibitors (PARPi). Here, we report the concept and characterization of a novel bifunctional PARPi (kt-3283) with dual activity toward PARP1/2 and HDAC enzymes in Ewing sarcoma cells. EXPERIMENTAL DESIGN Inhibition of PARP1/2 and HDAC was measured using PARP1/2, HDAC activity, and PAR formation assays. Cytotoxicity was assessed by IncuCyte live cell imaging, CellTiter-Glo, and spheroid assays. Cell-cycle profiles were determined using propidium iodide staining and flow cytometry. DNA damage was examined by γH2AX expression and comet assay. Inhibition of metastatic potential by kt-3283 was evaluated via ex vivo pulmonary metastasis assay (PuMA). RESULTS Compared with FDA-approved PARP (olaparib) and HDAC (vorinostat) inhibitors, kt-3283 displayed enhanced cytotoxicity in Ewing sarcoma models. The kt-3283-induced cytotoxicity was associated with strong S and G2-M cell-cycle arrest in nanomolar concentration range and elevated DNA damage as assessed by γH2AX tracking and comet assays. In three-dimensional spheroid models of Ewing sarcoma, kt-3283 showed efficacy in lower concentrations than olaparib and vorinostat, and kt-3283 inhibited colonization of Ewing sarcoma cells in the ex vivo PuMA model. CONCLUSIONS Our data demonstrate the preclinical justification for studying the benefit of dual PARP and HDAC inhibition in the treatment of Ewing sarcoma in a clinical trial and provides proof-of-concept for a bifunctional single-molecule therapeutic strategy.

Abstract
The flocculation performance of chitosan can be enhanced by grafting modification to overcome its disadvantages of poor water solubility. In this study, chitosan was modified by dielectric barrier discharge plasma and polymerized with acrylamide and aluminum chloride to synthesize a new chitosan-based flocculant, namely, chitosan-acrylamide-aluminum chloride (CA-PAC). After optimizing the synthesis conditions of CA-PAC, the best conditions were as follows: discharge time of 3 min, discharge power of 50 W, polymerization temperature of 60 °C, polymerization time of 3 h, total monomer concentration of 100 g/L, and m(AlCl3):m(CA) ratio of 2:1. Characterization was performed through SEM, XPS, FTIR, XRD, TG and 1H NMR. Results showed that the preparation of CA-PAC was successful. The influences of flocculant dosage, pH, and stirring intensity on flocculation efficiency were investigated. The removal efficiency of turbidity was 94.1 %. The investigation of the flocculation mechanism revealed that CA-PAC mainly relied on charge neutralization or the synergic action of electric neutralization, bridging, and roll-sweep under acidic and neutral conditions, but it depended on the joint action of adsorption bridging and net sweeping under alkaline conditions. This study provides new ideas for the preparation and development of modified chitosan and broadens its application in water treatment.

Abstract
The first complete mitochondrial genome of the dart sac-bearing camaenid Laeocathaica Möllendorff, 1899 was sequenced and analyzed in this study. The whole mitogenome of Laeocathaica amdoana Möllendorff, 1899 was 14,660 bp in length and its nucleotide composition showed high AT-content of 67.45%. It had 37 genes, including 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. The phylogeny yielded by both Bayesian inference and maximum-likelihood method suggested that Laeocathaica was closely related to the other dart sac-bearing camaenids with known complete mitochondrial genome. These genetic data are expected to provide fundamental resources for further genetic studies on the camaenids.

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
Abstract
Introduction: Poly(ADP-ribose) polymerase (PARP) plays a major role in DNA repair and PARP inhibitors (PARPi) have shown promise in pre-clinical studies for the treatment of Ewing sarcoma (ES). While a clinical trial using olaparib as a single agent failed to show significant response against ES, combination therapies with PARPi have emerged as an area of interest. Deacetylation of histones, controlled by histone deacetylases (HDACs) is a key regulatory event in DNA repair and inhibition of HDACs has been shown to reduce ES tumor growth in vitro and in vivo. PARP inhibition combined with HDAC inhibition has demonstrated enhanced efficacy in pre-clinical studies in various tumor indications, and a clinical trial of olaparib and vorinostat combination therapy against metastatic breast cancer is currently ongoing. However, combination therapies can be limited in clinical utility due to overlapping toxicities and different pharmacokinetic profiles. Here, we report the efficacy of a novel bifunctional small-molecule compound, kt-3283, designed to have both PARP and HDAC inhibitory activities.
Materials and methods: PARP1 and PARP2 activity were measured using Trevigen Universal Colorimetric PARP Assay Kit, BPS Bioscience PARP2 Colorimetric PARP2 Assay Kit, and PARylation assay. HDAC activity was measured using HeLa cell nuclear extracts and a fluorogenic peptide-based biochemical assay. Cell survival EC50s were determined using live cell imaging with an Incucyte® S3 system and CellTiter Glo viability assay. Cell cycle analysis was performed by flow cytometry with propidium iodide staining. DNA damage was investigated by western blot, immunofluorescence, and comet assay. Spheroid assays were performed using the Incucyte® S3 spheroid analysis module and inhibition of metastases was assessed in a PUMA ES mouse model.
Results and discussion: Kt-3283 showed potent inhibition of PARP1/2 activity and PAR synthesis with IC50 values comparable to olaparib. Kt-3283 also showed inhibition of HDACs with an IC50 value in the low µM range. Cell survival EC50 values for the compound were also superior to those of olaparib and vorinostat in ES cell lines. Cell cycle and DNA damage analyses indicated S/G2/M cell cycle arrest and strong DNA damage upon treatment with kt-3283 at lower concentration range compared to olaparib and vorinostat. This compound also exhibited potent inhibition of 3D spheroid growth of ES cells with low µM EC50 values, and inhibited metastatic growth in a PUMA mouse model.
Conclusion: Kt-3283 shows potent inhibition of PARP1/2 and HDAC activities. It induces S and G2/M cell cycle arrest and DNA damage, and inhibits 3D spheroid growth and metastatic potential of ES cells. Further investigation of this bifunctional single-molecule inhibitor may offer a novel treatment opportunity for ES and other solid tumors with limited responses to PARPi.

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
PURPOSE Evaluate the initial ocular safety and tolerability and efficacy of VVN001 Ophthalmic Solution (VVN001), a small-molecule antagonist of lymphocyte function-associated antigen-1 (LFA-1), in subjects with dry eye disease (DED). METHODS This was a multi-center, double-masked, randomized, dose-response, vehicle-controlled, parallel-group study conducted in 170 subjects with DED. Subjects were randomized to receive VVN001 (1% or 5%) or its vehicle, twice-daily in both eyes for 84 days. The primary outcome measure was inferior region corneal fluorescein staining (iCFS, 0-4 scale) at Day 84. Visual Analogue Scale eye dryness (VAS, 0-100 scale) was a secondary outcome. RESULTS The primary and first secondary outcomes were not met. At Day 84 treatment effects in favor of VVN001 5% relative to its vehicle for iCFS were 0.29 units (p = 0.054), and for VAS were 3.18 units (p = 0.533). In other secondary outcomes, treatment effects in favor of VVN001 5% relative to its vehicle were seen in total CFS (1.61 units, 0-20 scale, p = 0.004) and Schirmer score (1.77 and 2.32 mm, p = 0.049 and p = 0.17 at Days 14 and 28 respectively). Adverse events of incidence 5% or greater in either active treatment group were instillation site pain (3/57, 5.3%), dysgeusia (3/56, 5.4%) and urinary tract infection (3/57, 5.3%). CONCLUSIONS There were no major safety issues of note. Appropriately powered studies will be required with a priori selection of the efficacy endpoints to evaluate VVN001's therapeutic potential.

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
Central China harbors the native dart-sac-bearing camaenids Laeocathaica. The genus is revised and seven new species are proposed based on museum material and newly collected specimens. This work confirmed that most Laeocathaica species have restricted habitats. The comparison of the dart sac apparatus among the dart-sac-bearing camaenid genera indicated the importance of the presence of the proximal accessory sac that might be analogous to the membranous/muscular sac surrounding the proximal dart sac and/or the distal region of the vagina near the atrium, which also plays a significant role in the diagnosis of Laeocathaica species based on its number, symmetry and position on the dart sac. Species with similar shell morphology were studied using geometric morphometric methods to detect variations in shell shape. A molecular phylogenetic analysis based on 16S and ITS2 sequence data of partial Laeocathaica species and many other dart-sac-bearing taxa suggested that Laeocathaica might be monophyletic. Furthermore, the present phylogeny indicated that Stilpnodiscus, Cathaica, Bradybaena, and Pseudobuliminus might be polyphyletic and therefore the taxonomy of dart-sac-bearing camaenids in this region requires a thorough revision. This work reconfirms that the Southern Gansu Plateau is important as a hotspot for malacodiversity conservation on the Chinese mainland.

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
Tracheal tumors are rare, accounting for 0.1% of all malignancies. Squamous cell carcinoma and adenoid cystic carcinoma are the two most prevalent tracheal cancers. Less than 20 cases of extramedullary plasmacytoma in the trachea and main bronchus have ever been documented in the literature, making it extremely uncommon. Although the origin of these lesions is unclear, viral pathogenesis and persistent inflammation are thought to be the main causes. Clinically, these individuals exhibit vague symptoms such as stridor, a persistent cough, dyspnea, or wheezing, making a correct diagnosis difficult.

Abstract
BACKGROUND To investigate the correlation between the preoperative systemic immune-inflammation index (pSII) and postoperative pneumonia (POP) in surgical non-small cell lung cancer patients. METHODS Patients who underwent lung cancer surgery at West China Hospital of Sichuan University were retrospectively included. The indicators were collected, including basic information of patients, surgery-related variables and POP rate. The predictive value of the pSII in the occurrence of POP was analyzed. RESULTS A total of 1486 patients (male: 748, 50.3%; female: 738, 49.7%; mean age: 58.2 ± 9.7 years; median age: 59 years old, interquartile range: 51-65 years old) were finally included in the study, of which 142 patients had POP with an incidence of 9.5% (142/1486), 9.2% (69/748) in males, and 9.9% (73/738) in females. The proportion of patients with diabetes in the pneumonia group was significantly higher than that in the nonpneumonia group (9.8%, 14/142 vs. 5.6%, 75/1344, p = 0.041). Compared with the nonpneumonia group, the level of the preoperative body mass index (24.2 [21.9, 26.1] vs. 23.1 [21.1, 25.2], p = 0.003) and SII (487 [350, 673] vs. 345 [230, 500], p < 0.001) in the pneumonia group were significantly higher. Multiple factor analysis showed that the pSII (odds ratio: 1.001, 95% confidence interval: 1.000-1.001, p < 0.001) was an independent risk factor for POP (487 [350, 673] vs. 345 [230, 500], p < 0.001); receiver operating characteristic curve analysis showed that the pSII was effective in predicting POP (area under curve: 0.751, p < 0.001). CONCLUSION The pSII is closely related to and can effectively predict the occurrence of POP after lung cancer surgery.

Abstract
Objective To examine the efficacy and safety of ozonated autohemotherapy (O3-AHT) combined with pharmacological therapy for comorbid insomnia and myofascial pain syndrome (MPS). Materials and Methods One hundred and eighteen patients were randomly divided into two groups: the control group (N = 50) and the O3-AHT group (N = 53). Patients in both groups were given the same pharmacological management for three weeks. Patients in the O3-AHT group were treated with ozonated autohemotherapy (the concentration of ozone was 20 µg/ml in the first week, 30 µg/ml in the second week, and 40 µg/ml in the third week) combined with pharmacological therapy. Primary (the insomnia severity index (ISI) and visual analogue scale (VAS)) and secondary outcomes (the Epworth sleepiness scale (ESS), polysomnography data, the anxiety and preoccupation about sleep questionnaire (APSQ), the beck depression index (BDI), and the multidimensional fatigue inventory (MFI)) were examined at pretreatment, posttreatment, 1 month, and 6 months. Results Fifty patients in the control group and fifty-three patients in the O3-AHT group completed the study. In both groups, insomnia and pain symptoms were relieved significantly compared with pretreatment. Compared with the control group, the O3-AHT group had significantly improved sleep quality, pain, and negative mood at different time points. No adverse complications were observed in either group. Conclusion Compared with pharmacological therapy alone, ozonated autohemotherapy combined with pharmacological therapy can ameliorate insomnia, reduce pain intensity, improve negative mood, and alleviate fatigue more effectively without serious adverse complications.

Abstract
Due to their atomically ultrathin thickness, the development of high-performance transition-metal dichalcogenides (TMDCs) based photodetectors demands device designs distinct from architectures adopted in conventional bulk semiconductor devices. Here, we demonstrate a field-induced Schottky barrier photodiode with three different TMDC materials, WSe2, MoTe2, and WS2. Owing to the high gate efficiency of a high-κ dielectric film, the Schottky barrier at metal contacts is effectively modulated by external bias, giving rise to a strong diode-like rectifying characteristic with high current on/off ratio. The WSe2 photodiode shows a linear dynamic range of 112 dB, a responsivity of 0.17 A/W, and response time of 8 ns. When this fast WSe2 device is employed for visible light communication data linking, a maximum real-time data transmission rate of 110 Mbps is achieved. Meanwhile, infrared light communication was also realized with a maximum data rate of 30 Mbps using a field-induced MoTe2 Schottky barrier photodiode as a light sensor. This work provides a general CMOS-compatible and controllable fabrication strategy for TMDC-based photodetectors.

Abstract
Abstract
Introduction: Inhibition of poly-adenosine diphosphate-ribose polymerase (PARP) is an effective therapy against cancers with DNA damage repair (DDR) deficiencies, such as BRCA1 and BRCA2 defects. In preclinical studies, PARP inhibitors demonstrated potential therapeutic value in Ewing sarcoma (ES), though clinical trials with olaparib failed to show significant clinical benefit. While single agent therapy proved inefficacious in the clinical treatment of ES, combination therapies may show anti-tumour activity. A key regulatory event in DNA damage repair is acetylation and deacetylation of histones, controlled by histone acetyltransferases (HATs) and histone deacetylases (HDACs). Increased expression of HDACs have been correlated to more malignant phenotypes in sarcomas and inhibition of HDAC in ES has been shown to be effective in inhibiting tumor growth. HDAC inhibition combined with PARP inhibition has been shown to sensitize cells to treatment in vitro, however clinically, combination therapies often require sequential administration due to different pharmacokinetic profiles and overlapping toxicities, severely limiting clinical utility. Here, we evaluate the activity and efficacy of a novel bifunctional small-molecule compound designed to have both PARP and HDAC inhibiting activity. Methods: PARP1 activity was measured using the Trevigen Universal Colorimetric PARP Assay Kit and PARP2 activity was measured using the BPS Bioscience PARP2 Colorimetric PARP2 Assay Kit. HDAC activity was measured using HeLa nuclear extracts and a fluorogenic peptide-based biochemical assay. Cell survival EC50s were determined using live cell imaging with an Incucyte S3 system and the CellTiter Glo viability assay. Accumulation of phospho-histone H2AX (pH2AX) was detected by western blot using anti-phospho histone H2AX (Ser139) antibody from Cell Signaling Technologies. Results: A representative compound from the kt-3000 series showed potent inhibition of PARP1 and PARP2 with IC50 values in the low nM range, comparable to FDA-approved PARP inhibitors. The compound also showed inhibition of HDAC enzymes with IC50 values in the low µM range, slightly lower than the FDA-approved HDAC inhibitor, vorinostat. Cell survival EC50 values were superior to olaparib in ES cell lines in vitro. Treatment with the kt-3000 compound also resulted in the increased accumulation of pH2AX by western blot and increased S and G2/M cell cycle arrest compared to olaparib. Conclusion: Our kt-3000 compound shows potent inhibition of PARP1, PARP2, and HDAC, as well as induction of DNA damage and cell cycle arrest. Further development of these bifunctional single molecule inhibitors may result in a novel treatment opportunity for Ewing sarcoma.

Abstract
Siderophore is necessary for the survival of microorganisms and is interregulated with quorum sensing (QS) systems. It is related to growth, proliferation, virulence, and other bacterial social activities as a virulence factor. Thus, we speculated that the QS system could be occluded by inhibiting siderophore production. 2-Hydroxymethyl-1-methyl-5-nitroimidazole (HMMN), one siderophore inhibitor of Pseudomonas aeruginosa PAO1 (P. aeruginosa PAO1), was obtained by using the Chromeazurol S (CAS) method. We found that HMMN inhibited siderophore production and influenced the biological effects of QS regulation, including biofilm formation and pyocyanin production. HMMN (150 μg/ml) inhibited the siderophore production of P. aeruginosa PAO1 by 69.37%. In addition, HMMN could inhibit pyocyanin production and biofilm formation and erase the formed biofilm of P. aeruginosa PAO1. HMMN (150 μg/ml) inhibited the biofilm formation of P. aeruginosa PAO1 by 28.24%. The erasure rate of the formed biofilm reached 17.03%. Furthermore, HMMN (150 μg/ml) inhibited P. aeruginosa PAO1 pyocyanin production by 36.06%. Meanwhile, positive-control hordenine (500.0 μg/ml) reduced the biofilm formation and pyocyanin production of P. aeruginosa PAO1 by 14.42% and 34.35%, respectively. The erasure rate of hordenine to the formed biofilm is 11.05% at 500 μg/ml. Quantitative real-time polymerase chain reaction (qRT-PCR) showed that HMMN downregulates not only siderophore-related genes but also QS-related genes, as well as hordenine. These results suggest that a siderophore inhibitor could be used as a QS inhibitor to occlude the QS system and reduce virulence.

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
Pulmonary mucoepidermoid carcinoma (PMEC) is uncommon. The purpose of this study was to evaluate the clinicopathological features, diagnostic criteria, treatment options, and prognostic factors relating to primary PMEC. Clinical data on 45 patients with primary PMEC were collected and analyzed retrospectively at Tianjin Medical University General Hospital and the First People' Hospital of Longquanyi District Chengdu from January 2008 to December 2020. The 45 patients (25 males and 20 females) ranged in age from 22 to 72 years, with a median age of 49 and an average age of 47.7. All the patients underwent surgery, with 32 receiving only surgery and 13 receiving both surgery and postoperative chemotherapy. A total of 34 instances of low-grade tumors and 11 cases of high-grade tumors were discovered during postoperative pathological diagnosis. Forty-five patients were followed for 13 to 78 months, and four died during this period. In all four instances, a lung infection unrelated to the tumor was determined to be the cause of death. The MAML2 gene translocation was detected in 40 of 45 patients, with 34 of them testing positive. Radical surgery with lymph node dissection is an efficient treatment for PMEC. The prognosis is poor for patients with advanced disease, a negative MAML2 gene translocation, lymph node metastases, and high-grade tumors.

Abstract
Abstract
Introduction: Poly-adenosine diphosphate-ribose polymerase (PARP) inhibition is an effective, FDA-approved treatment against cancers with DNA damage repair (DDR) deficiencies, such as BRCA1 or BRCA2 mutations. PARP is a core component of single-strand break repair, so in tumors with DDR deficiencies, double-strand breaks (DSBs) and single-strand breaks (SSBs) accumulate and lead to cell death. Combining PARP inhibition with other DNA-damaging therapies, such as DNA alkylating agents, has proven to be more effective than PARP inhibition alone, as DNA alkylators can lead to the formation of DSBs. However, combination therapies often require sequential administration due to pharmacokinetic considerations and overlapping toxicities, severely limiting their clinical utility. Here, we evaluate a novel class of PARP inhibitors combined with DNA alkylating functionality, in formulation as a single molecule.
Methods: PARP1 activity was determined using the Trevigen Universal Colorimetric PARP Assay Kit and PARP2 activity was determined using the BPS Bioscience PARP2 Colorimetric Assay Kit. Methylator release was evaluated by measuring the appearance of a certain degradation product. Cell cycle analysis was performed using propidium iodide staining and quantified using flow cytometry. pH2AX expression as a measure of DNA double strand breaks (DSB) was quantified by flow cytometry using an Alexa Fluor 647-conjugated anti-H2AX phospho (Ser139) antibody from BioLegend. Detection of pH2AX by western blot and immunofluorescence assays was done using anti-phospho histone H2AX (Ser139) antibody from Cell Signaling Technologies.
Results: kt-4000 series compounds are potent inhibitors of both PARP1 and PARP2 with IC50 values in the low nM range, comparable to FDA-approved PARP inhibitors. The compounds release methylator in a similar manner as temozolomide, an FDA-approved DNA alkylating agent. They induce S-phase and G2/M cell cycle arrest in MCF7 cells and lead to accumulation of pH2AX by flow cytometry, western blot, and immunofluorescence assays.
Conclusion: Our novel class of PARP inhibitors combined with DNA alkylating function show potent inhibition of both PARP1 and PARP2. These compounds also lead to accumulation of H2AX phosphorylation, a sensitive marker for double-strand breaks, and S-phase and G2/M cell cycle arrest. Development of these bifunctional, single molecule therapies may extend the clinical utility of PARP inhibitors to DDR proficient disease and increase efficacy for DDR deficient disease.

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
Abstract
Introduction: Inhibition of poly adenosine diphosphate-ribose polymerase (PARP) is an effective treatment strategy against tumors with homologous recombination (HR) DNA repair deficiencies. Combination treatments utilizing PARP inhibitors (PARPi) in concert with inhibitors of key DNA repair or PARPi-resistance pathways, may expand the utility of PARPi beyond cancers harboring germ-line HR deficiencies. Acetylation and deacetylation of histones is an important regulatory event in the DNA damage response. Combining histone deacetylation inhibitors (HDACi) and PARPi have sensitized PARPi-resistant cells to treatment; however, combination regimens often require sequential administration to manage overlapping toxicities and accommodate diverse pharmacokinetics, constituting a significant limitation of these strategies in a clinical setting. Here, we test the activity of kt-3000 series, a novel bi-functional class of small molecules with dual PARP and HDAC inhibitor activity in HR-proficient cancer cells where PARPi have historically lacked single-agent activity. Methods: PARP enzyme activity was measured using the Trevigen Universal Colorimetric PARP Assay Kit. HDAC activity was measured using nuclear extracts of treated cells and the HDAC Fluorometric Activity Assay Kit from Cayman Chemical, as per the manufacturer’s protocol. PARP activity was measured by fluorescence in C41 cells following compound treatment for 2 hours and PARP-activation with 1M H2O2 by staining cells with an anti-PARP Ab followed by a FITC-coupled secondary antibodies. Cell survival EC50 values were obtained by treating cells with a range of inhibitor concentrations, then quantifying cell confluency after 72-hours of treatment based on images taken with an Incucyte S3 system. Results: kt-3000 series compounds are potent inhibitors of PARP and HDAC with IC50 values for PARP enzyme activity in the low nM range, comparable to those of FDA-approved PARP inhibitors (olaparib, rucaparib, niraparib, and talazoparib) and IC50 values for the inhibition of HDAC activity comparable to FDA-approved HDAC inhibitors (panabinostat, belinostat, and vorinostat). Fluorescent assays of PARP activity in C41 cells also resulted in IC50 values in the nM range and cell survival EC50 values of the dual inhibitors are comparable to FDA-approved PARP inhibitors alone and in similar range with FDA-approved HDAC inhibitors alone. Conclusion: Our novel dual PARP-HDAC inhibitors show potent inhibition of PARP activity in vitro comparable to FDA-approved PARP inhibitors and also show potent inhibition of HDAC activity. The potency and activity of kt-3000 series compounds exhibit potential superiority to FDA-approved PARP inhibitors and HDAC inhibitors, in formulation as a single molecule. Development of these multi-target inhibitors will target unmet medical needs in the treatment of HR-proficient cancer types with dysregulation of histone deacetylation.

Abstract
Abstract
CNS metastases are a prominent driver of cancer morbidity and mortality, especially as targeted therapies have improved systemic outcomes. Mutations in the ErbB/HER kinase family are known oncodrivers in many cancers. Extensive crosstalk among ErbB/HER receptors suggests that inhibition of multiple family members may benefit treatment and limit drug resistance. There is a desperate need for new agents that are more tolerable and effective in treating CNS metastases. EO1001 (APL-122) is a first-in-class, oral, irreversible pan-ErbB inhibitor targeting ErbB1, ErbB2 and ErbB4 with promising CNS penetration in preclinical models. Preclinical data suggests a favorable pharmacokinetic and safety profile and activity against ErbB-driven cancers in patient-derived xenograft models. We report on a first-in-human Phase 1-2 clinical trial in progress. Adult participants with confirmed ErbB-positive cancer, including patients with CNS involvement, who have progressed after standard-of-care, with adequate bone marrow, renal and liver function are eligible. ESCALATION: One subject per dose cohort is enrolled in an accelerated dose-escalation design until drug-related toxicity (≥G2) is observed in the first cycle, after which dose escalation will revert to a 3 + 3 design to determine the maximum tolerated dose (MTD). Cycle 1: Patients receive a single oral dose of EO1001 on day 1; single-dose pharmacokinetics are measured. Beginning on day 8, EO1001 is administered once daily for 21 days; multi-dose pharmacokinetics are measured. Cycles 2-6: EO1001 is administered once daily in continuous 28-day cycles for up to 20 weeks. EXPANSION: EO1001 will be administered once daily to 20 patients at the MTD in continuous 28-day cycles for up to 6 cycles to determine a recommended Phase 2 dose (RP2D) for further study. Toxicity is assessed based on NCI CTCAEv5 and tumor response is assessed by RECIST 1.1. CNS exposure is evaluated in patients via CSF collection with confirmed CNS disease involvement.

Abstract
The occurrence of ureteral metastasis from distant primary tumors is uncommon, and appears to be especially rare when it originates from the lungs. In the case presented here, a patient with lumbago and left hydronephrosis was diagnosed with left ureteral metastasis of pulmonary adenocarcinoma after a CT‐guided percutaneous transthoracic needle biopsy of the lung and retroperitoneal laparoscopic left nephroureterectomy. He accepted the targeted therapy because the lung tumor epidermal growth factor receptor mutation (exon19 deletion) was positive, and preoperative staging of lung adenocarcinoma was stage IVA. After an 8‐month follow‐up, he is still alive and well, with no local recurrence or distant metastases. The therapy outcome assessment is stable disease. Although rare, our case has demonstrated that pulmonary adenocarcinoma has the possibility of metastasizing to the ureter, a risk that should be considered in some lung cancer patients.

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
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.
