Abstract
Immune checkpoint inhibitors targeting the programmed cell death-1 (PD-1) protein significantly improve survival in patients with advanced non-small-cell lung cancer (NSCLC), but its impact on early-stage ground-glass opacity (GGO) lesions remains unclear. This is a single-arm, phase II trial (NCT04026841) using Simon's optimal two-stage design, of which 4 doses of sintilimab (200 mg per 3 weeks) were administrated in 36 enrolled multiple primary lung cancer (MPLC) patients with persistent high-risk (Lung-RADS category 4 or had progressed within 6 months) GGOs. The primary endpoint was objective response rate (ORR). T/B/NK-cell subpopulations, TCR-seq, cytokines, exosomal RNA, and multiplexed immunohistochemistry (mIHC) were monitored and compared between responders and non-responders. Finally, two intent-to-treat (ITT) lesions (pure-GGO or GGO-predominant) showed responses (ORR: 5.6%, 2/36), and no patients had progressive disease (PD). No grade 3-5 TRAEs occurred. The total response rate considering two ITT lesions and three non-intent-to-treat (NITT) lesions (pure-solid or solid-predominant) was 13.9% (5/36). The proportion of CD8+ T cells, the ratio of CD8+/CD4+, and the TCR clonality value were significantly higher in the peripheral blood of responders before treatment and decreased over time. Correspondingly, the mIHC analysis showed more CD8+ T cells infiltrated in responders. Besides, responders' cytokine concentrations of EGF and CTLA-4 increased during treatment. The exosomal expression of fatty acid metabolism and oxidative phosphorylation gene signatures were down-regulated among responders. Collectively, PD-1 inhibitor showed certain activity on high-risk pulmonary GGO lesions without safety concerns. Such effects were associated with specific T-cell re-distribution, EGF/CTLA-4 cytokine compensation, and regulation of metabolism pathways.

Abstract
Modifying perovskite surface using various organic ammonium halide cations has proven to be an effective approach for enhancing the overall performance of perovskite solar cells. Nevertheless, the impact of the structural symmetry of these ammonium halide cations on perovskite interface termination has remained uncertain. Here, this work investigates the influence of symmetry on the performance of the devices, using molecules based on symmetrical bis(2-chloroethyl)ammonium cation (B(CE)A+ ) and asymmetrical 2-chloroethylammonium cation (CEA+ ) as interface layers between the perovskite and hole transport layer. These results reveal that the symmetrical B(CE)A+ cations lead to a more homogeneous surface potential and more comprehensive chelation with uncoordinated Pb2+ compared to the asymmetrical cations, resulting in a more favorable energy band alignment and strengthened defect healing. This strategy, leveraging the spatial geometrical symmetry of the interface cations, promotes hole carrier extraction between functional layers and reduces nonradiative recombination on the perovskite surface. Consequently, perovskite solar cells processed with the symmetrical B(CE)A+ cations achieve a power conversion efficiency (PCE) of 25.60% and retain ≈91% of their initial PCE after 500 h of maximum power point operation. This work highlights the significant benefits of utilizing structurally symmetrical cations in promoting the performance and stability of perovskite solar cells.

Abstract
Erythro-myeloid progenitors of the yolk sac that originates during early embryo development has been suggested to generate tissue-resident macrophage, mast cell, and even endothelial cell populations from fetal to adult stages. However, the heterogeneity of erythro-myeloid progenitors (EMPs) is not well characterized. Here, we adapt single-cell RNA sequencing to dissect the heterogeneity of EMPs and establish several fate-mapping tools for each EMP subset to trace the contributions of different EMP subsets. We identify two primitive and one definitive EMP subsets from the yolk sac. In addition, we find that primitive EMPs are decoupled from definitive EMPs. Furthermore, we confirm that primitive and definitive EMPs give rise to microglia and other tissue-resident macrophages, respectively. In contrast, only Kit+ Csf1r- primitive EMPs generate endothelial cells transiently during early embryo development. Overall, our results delineate the contribution of yolk sac EMPs more clearly based on the single-cell RNA sequencing (scRNA-seq)-guided fate-mapping toolkit.

Abstract
OBJECTIVES Sublobar resection, including wedge resection and segmentectomy, is non-inferior to lobectomy in early-stage non-small cell lung cancer treatment. We aimed to compare the risk of postoperative cognitive dysfunction (POCD) between sublobar resection and lobectomy. METHODS We conducted a prospective cohort study. Patients with sublobar resection or lobectomy were divided into the sublobar group or the lobar group, respectively. Cognition was assessed before and after surgery with Montreal Cognitive Assessment and Minimum Mental State Examination tests. POCD is defined as Z score of Montreal Cognitive Assessment change ≤-1.96. Propensity score matching (PSM) was performed to make demographics well-balanced between the 2 groups. RESULTS A total of 335 patients were enrolled. Both the postoperative 1-day POCD rate (sublobar 5.5% vs lobar 18.2%, P < 0.001) and the postoperative 1-month POCD rate (sublobar 7.9% vs lobar 21.8%, P < 0.001) were significantly lower in the sublobar group compared with lobar group, with demographics unbalanced between the 2 groups. In the 133 demographics-matched pairs obtained by PSM, both the postoperative 1-day POCD rate (sublobar 5.3% vs lobar 17.3%, P = 0.005) and the postoperative 1-month POCD rate (sublobar 8.3% vs lobar 18.8%, P = 0.018) remained significantly lower in the sublobar group than in the lobar group. The incidences of postoperative 1-day (P = 0.109) and postoperative 1-month (P = 0.026) Minimum Mental State Examination abnormity were also lower in the sublobar group than in the lobar group but only the latter was with statistical significance after PSM. CONCLUSIONS Sublobar resection has an advantage over lobectomy in preventing POCD. Our findings might be a reference for selecting the most suitable type of resection for non-small-cell lung cancer patients.

Abstract
BACKGROUND Mediastinal neoplasms are typical thoracic diseases with increasing incidence in the general global population and can lead to poor prognosis. In clinical practice, the mediastinum's complex anatomic structures and intertype confusion among different mediastinal neoplasm pathologies severely hinder accurate diagnosis. To solve these difficulties, we organised a multicentre national collaboration on the basis of privacy-secured federated learning and developed CAIMEN, an efficient chest CT-based artificial intelligence (AI) mediastinal neoplasm diagnosis system. METHODS In this multicentre cohort study, 7825 mediastinal neoplasm cases and 796 normal controls were collected from 24 centres in China to develop CAIMEN. We further enhanced CAIMEN with several novel algorithms in a multiview, knowledge-transferred, multilevel decision-making pattern. CAIMEN was tested by internal (929 cases at 15 centres), external (1216 cases at five centres and a real-world cohort of 11 162 cases), and human-AI (60 positive cases from four centres and radiologists from 15 institutions) test sets to evaluate its detection, segmentation, and classification performance. FINDINGS In the external test experiments, the area under the receiver operating characteristic curve for detecting mediastinal neoplasms of CAIMEN was 0·973 (95% CI 0·969-0·977). In the real-world cohort, CAIMEN detected 13 false-negative cases confirmed by radiologists. The dice score for segmenting mediastinal neoplasms of CAIMEN was 0·765 (0·738-0·792). The mediastinal neoplasm classification top-1 and top-3 accuracy of CAIMEN were 0·523 (0·497-0·554) and 0·799 (0·778-0·822), respectively. In the human-AI test experiments, CAIMEN outperformed clinicians with top-1 and top-3 accuracy of 0·500 (0·383-0·633) and 0·800 (0·700-0·900), respectively. Meanwhile, with assistance from the computer aided diagnosis software based on CAIMEN, the 46 clinicians improved their average top-1 accuracy by 19·1% (0·345-0·411) and top-3 accuracy by 13·0% (0·545-0·616). INTERPRETATION For mediastinal neoplasms, CAIMEN can produce high diagnostic accuracy and assist the diagnosis of human experts, showing its potential for clinical practice.

Abstract
Epoxy vitrimers appear as a promising alternative to common epoxy thermoset composites. Nevertheless, the possibilities of applying these materials are limited due to their high flammability which may cause high fire risks. To date, the flame-retardant epoxy vitrimer systems reported in the literature almost all rely on intrinsic flame retardancy to achieve high fire safety; however, the complex and expensive synthesis process hinders their large-scale application. In this work, disulfide-based epoxy vitrimer (EPV) was fabricated with 4, 4'-dithiodianiline as the curing agent, and microencapsulated ammonium polyphosphate (MFAPP) was employed as a potential additive flame retardant to improve their fire retardancy. As a comparative study, common epoxy (EP) composites were also prepared using 4,4'-diaminodiphenylmethane as the curing agent. The results showed that the introduction of dynamic disulfide bonds led to a reduction in the initial thermal decomposition temperature of EPV by around 70 °C compared to EP. Moreover, the addition of 7.5 wt.% of MFAPP endowed EP with excellent fire performance: the LOI value was as high as 29.9% and the V-0 rating was achieved in the UL-94 test (3.2 mm). However, under the same loading, although EPV/MFAPP7.5% showed obvious anti-dripping performance, it did not reach any rating in the UL-94 test. The flame-retardant mechanisms in the condensed phase were evaluated using SEM-EDS, XPS, and Raman spectroscopy. The results showed that the residue of EPV/MFAPP7.5% presented numerous holes during burning, which failed to form a continuous and dense char layer as a physical barrier resulting in relatively poor flame retardancy compared to EP/MFAPP7.5%.

Abstract
OBJECTIVES The objective of the study was to evaluate the therapeutic effects of carbon quantum dots (CQDs) in immunomodulation on non-obese diabetic (NOD) mice, as the model for Sjögren's syndrome (SS). METHODS Carbon quantum dots were generated from Setaria viridis via a hydrothermal process. Their toxic effects were tested by cell viability and blood chemistry analysis, meanwhile therapeutic effects were investigated in NOD mice in the aspects of saliva flow, histology, and immune cell distribution. RESULTS Carbon quantum dots, with rich surface chemistry and unique optical properties, showed non-cytotoxicity in vitro or no damage in vivo. Intravenously applied CQDs alleviated inflammation in the submandibular glands in NOD mice after 6-week treatments. The inflammatory area index and focus score were significantly decreased in CQD-treated mice. Besides, the levels of anti-SSA and anti-SSB were decreased in the presence of CQDs. The stimulated saliva flow rates and weight of submandibular glands were significantly increased in CQD-treated mice by reducing the apoptosis of cells. The CD3+ and CD4+ T cells distributed around the ducts of submandibular glands were significantly decreased, while the percentage of Foxp3+ cells was higher in CQD-treated mice than that in the control group. CONCLUSIONS Our findings suggest that CQDs may ameliorate the dysregulated immune processes in NOD mice.

Abstract
Sequential deposition has been widely employed to modulate the crystallization of perovskite solar cells because it can avoid the formation of nucleation centers and even initial crystallization in the precursor solution. However, challenges remain in overcoming the incomplete and random transformation of PbI2 films with organic ammonium salts. Herein, a unique intermediate phase engineering strategy has been developed by simultaneously introducing 2,2-azodi(2-methylbutyronitrile) (AMBN) to both PbI2 and ammonium salt solutions to regulate perovskite crystallization. AMBN not only coordinates with PbI2 to form a favorably mesoporous PbI2 film due to the coordination between Pb2+ and the cyano group (C≡N), but also suppresses the vigorous activity of FA+ ions by interacting with FAI, leading to the full PbI2 transformation with the preferred orientation. Therefore, perovskites with favorable facet orientations are obtained, and the defects are largely suppressed owing to the passivation of uncoordinated Pb2+ and FA+ . As a result, a champion power conversion efficiency over 25% with a stabilized efficiency of 24.8% is achieved. Moreover, the device exhibits an improved operational stability, retaining 96% of initial power conversion efficiency under 1000 h continuous white-light illumination with an intensity of 100 mW cm-2 at ≈55 °C in N2 atmosphere.

Abstract
Objective: To summarize the clinical characteristics of bronchial-pulmonary artery fistula and evaluate the effect of interventional closure of bronchial-pulmonary artery fistula. Methods: A retrospective case study was conducted. Fifteen children with hemoptysis who were diagnosed with bronchial-pulmonary artery fistula in Beijing Children's Hospital, Capital Medical University from January 2018 to March 2022 were selected. Their clinical symptoms and chest-enhanced CT findings were recorded. The children who failed to improve after anti-infection and hemostasis treatment were treated with transcatheter embolization through microparticles under digital subtraction angiography (DSA). The efficacy and post-operation recurrence were evaluated. Results: There were 15 children, including 9 males and 6 females, aged 9.8 (3.7, 12.1) years, weighing 35 (16, 55) kg. There was hemoptysis of varying degrees before surgery. Only 2 children had decreased hemoglobin. Chest enhanced CT showed that their bronchial arteries were thickened and tortuous, including 11 cases of single vessel disease and 4 cases of multivessel disease; 11 children had varying degrees of pneumonia and 4 children had atelectasis. Except for one case effectively treated with medical therapy, the remaining 14 cases were all treated with transcatheter interventional closure with embolic microparticles, among whom 12 had their fistula completely blocked with a single operation and the other 2 children underwent multiple operations because of too many fistulas. One child had extensive bronchial-pulmonary artery fistula which failed to be blocked completely even after multiple operations. Among the remaining 13 children, only 2 patients whose fistula was considered to be completely closed had recurrence presenting with hemoptysis at 3 months and 2 years after the operation, and no hemoptysis was found after the second closure. All children were discharged without chest pain, spinal cord paraplegia, or other serious complications. Fourteen children were followed up for 1.4 (0.9,2.9) years, among whom one still has intermittent mild hemoptysis due to incomplete closure and the rest had a satisfactory outcome. Conclusions: Hemoptysis is the first symptom of bronchial-pulmonary artery fistula. For children with failed medical treatment, transcatheter closure with an embolic pellet is effective, safe and feasible, with a low recurrence rate.

Abstract
Lead halide perovskite single crystals have attracted wide interest in the field of X-ray detection due to their excellent photophysical properties. However, their inherent toxicity and high thickness restrict their applications in flexible devices. In this paper, designing a micronanometer-scale X-ray detector based on all-inorganic lead-free CsAg2I3 (CAI) single crystal microbelts (MBs) has addressed the above issues. These CAI single crystal MBs can be synthesized on various substrates with high crystal quality and excellent stability. Based on their excellent characteristics of the CAI MBs, we fabricate single CAI MB devices with an Au/CAI/Au structure, which shows not only good ultraviolet photoresponse characteristics, but also excellent X-ray detection performance. The optimized CAI photodetectors exhibit a responsivity of 23.59 mA/W, a high detectivity of 1010 Jones, and a fast response speed. For X-ray detection performance, a sensitivity of up to 515.49 μC Gyair-1 cm-2 and a detection limit of as low as 14.65 μGyair s-1 are achieved with outstanding operation stability and excellent long-term stability. Furthermore, our devices also showed excellent applicability for X-ray imaging, which is promising for their use in X-ray detection and imaging. Finally, flexible X-ray detectors are fabricated by using thin CAI single-crystal MBs and demonstrate good flexibility under different bending radii and bending cycles. Our work shows the potential for developing highly sensitive flexible integrated micro/nano optoelectronic devices by using lead-free perovskite analogue single crystals.

Abstract
Wide bandgap (WBG) perovskites through tuning iodine/bromine ratios are capable of merging with narrow bandgap organic bulk heterojunctions to construct tandem solar cells to overcome the Shockley-Queisser limitation. However, WBG perovskites readily suffer from light-induced halide ion migration, leading to detrimental phase segregation and hence severe open-circuit voltage (VOC ) loss. Here, to solve this issue, lead thiocyanate (Pb(SCN)2 ) and 2-thiopheneethylammonium chloride (TEACl) are synergistically employed to passivate and stabilize WBG perovskites with 1.79 eV bandgap. It is demonstrated that the synergetic employment of Pb(SCN)2 and TEACl suppresses light-induced phase segregation, passivates WBG perovskite defects, and reduces non-radiative recombination, hence alleviating VOC loss. As a result, optimized WBG perovskite solar cells (PSCs) are obtained with an impressive VOC of 1.26 V and power conversion efficiency (PCE) over 17.0%. Furthermore, the interconnection layer is optimized to minimize the VOC loss and construct two-terminal perovskite/organic tandem solar cells with a narrow bandgap organic blend bulk heterojunction of PM6:Y6 and achieve a champion PCE of 22.29% with a high VOC of 2.072 V. In addition, these tandem solar cells maintain 81% of their initial efficiency after 1000 h continuous tracking at the maximum power point (MPP) under 100 mW cm-2 white light illumination.

Abstract
The fluorescent carbon dots (CDs) have found their extensive applications in sensing, bioimaging, and photoelectronic devices. In general terms, the synthesis of CDs is straight-forward, though their subsequent purification can be laborious. Therefore, there is a need for easier ways to generate solid CDs with a high conversion yield. Herein, we used collagen waste as a carbon source in producing solid CDs through a calcination procedure without additional chemical decomposition treatment of the raw material. Considering a mass of acid has destroyed the original protein macromolecules into the assembled structure with amino acids and peptide chains in the commercial extraction procedure of collagen product. The residual tissues were assembled with weak intermolecular interactions, which would easily undergo dehydration, polymerization, and carbonization during the heat treatment to produce solid CDs directly. The calcination parameters were surveyed to give the highest conversion yield at 78%, which occurred at 300°C for 2 h. N and S atomic doping CDs (N-CDs and S-CDs) were synthesized at a similar process except for immersion of the collagen waste in sulfuric acid or nitric acid in advance. Further experiments suggested the prepared CDs can serve as an excellent sensor platform for Fe3+ in an acid medium with high anti-interference. The cytotoxicity assays confirmed the biosafety and biocompatibility of the CDs, suggesting potential applications in bioimaging. This work provides a new avenue for preparing solid CDs with high conversion yield.

Abstract
This study was designed to investigate the potential key genes of ADP-ribosylation factor-like 15 (ARL15) regulating glycolysis and lipogenesis in colon cancer. Hematoxylin-eosin (HE) staining and immunohistochemistry were used to observe the expression of ARL15 in 10 normal colon tissues and 10 colon cancer tissues. Immunofluorescence staining was used to observe the expression position of ARL15 in normal human colorectal mucosa cells (FHC) and colon cancer cells (HCT116 and SW620) with a confocal microscope. The ARL15 plasmid and small interfering RNA (siRNA) were constructed. After transfection, the expression levels of glycolysis and lipogenesis regulatory enzymes and messenger RNA (mRNA) transcription of ARL15 in over-expressed and silenced colon cancer cells were detected by Western blotting and real-time quantitative PCR (qRT-PCR). High expression of ARL15 in colon cancer tissue and low expression in normal colon tissue, and all expression are in the cytosol. The expression position of ARL15 in the FHC, HCT116, and SW620 cells was consistent and mainly distributed in the cytosol. After the pCMV-3Tag-2-ARL15 plasmid was transfected in HCT116, the protein expressions of FASN, AKT, P-AKT, P-GSK, SREBP-1 (p125) (p<0.01), and AMPK (p<0.001) were higher than those in the control group. The mRNA transcription level of FASN, GSK, AMPKa1, and SREBP-1 gene was higher than control group after the over-expression of ARL15. After the ARL15-siRNA was transfected in HCT116, the protein expression levels of PKM2, PFK, FASN, AKT, P-AKT, P-GSK, and AMPK decreased compared with the control group, (p<0.05). The mRNA transcription level of FASN, GSK, AMPKα1 gene was lower than control group after the low-expression of ARL15 (p<0.05). After adding 2 μM JIB-04, ARL15 in HCT116 showed statistical differences compared with the control group at 12 h, 24 h and 36 h (p<0.05). After adding 2 μM JIB-04, the protein expression levels of AKT, p-GSK, FASN, AMPK and SREBP-1 in HCT116 cells decreased significantly after 24 h. It was also found that the expression levels of AKT, P-GSK, FASN, AMPK and SREBP-1 genes in the dose-adding group were significantly lower than those in the control group. In summary, ARL15 may promote the occurrence of colon cancer by increasing the expression of protein kinase B/AMP-activated protein kinase (AKT/AMPK) downstream regulatory enzymes for glycogenesis and lipogenesis. JIB-04 can target ARL15 and affect its expression as well as the expressions of glucose and lipid metabolity-related proteins in AKT and AMPK signaling pathways.

Abstract
Lithium-sulfur (Li-S) batteries have attracted a great deal of attention for the next-generation energy storage devices due to their inherently high theoretical energy density, high natural abundance, and low cost. However, the dissolution of polysulfides in electrolytes and their undesirable shuttle behavior lead to poor cycling performance, which obstructs practical application. Herein, we report a dual-sulfur-fixing mechanism of epoxy/allyl compound/sulfur system to prepare poly(sulfur-random-4-vinyl-1,2-epoxycyclohexane) (SVE) copolymers as powerful cathode materials. Benefiting from the stable C-S bond and a uniform distribution of ultrafine Li2S/S8 in the SVE-based polymer matrix, the SVE electrodes exerted an embedding effect to reduce polysulfides migration. The thiosulfate/polythionate protective layer derived from the terminal hydroxyl group of SVE also ensured the cycle stability of SVE electrodes during cycling. As a result, optimized SVE electrodes deliver a high reversible specific capacity of 1248 mA h g-1 at rates of 0.1 C, together with a stable cycling performance of no capacity decay per cycle over more than 400 cycles. This work provides an effective strategy for the practical application of organosulfur polymers Li-S batteries and inspires the exploration of the reaction mechanism of epoxy/allyl compound/sulfur system.

Abstract
Low isobutanol tolerance of Saccharomyces cerevisiae limits its application in isobutanol fermentation. Here, we used global transcription machinery engineering to screen mutants with higher isobutanol tolerance and elevated isobutanol titres. TATA-binding protein Spt15 was used as the target of global transcription machinery engineering for improvement of such complex phenotypes. A random mutagenesis library of S. cerevisiae TATA-binding protein Spt15 was constructed and subjected to screening under isobutanol stress. A mutant strain (denoted as spt15-3) with improved isobutanol tolerance was identified. There were three mutations of Spt15 in strain spt15-3, including deletion of A at position -132 nt upstream of initiation codon, insertion of G at position -65 nt upstream of initiation codon and a synonymous mutation at position 315 nt (T → C) downstream of initiation codon. We then metabolically engineered isobutanol synthesis in strains harbouring plasmids YCplac22 containing these Spt15 mutations. Delta integration was used to overexpress ILV3 gene, and 2μ plasmids carrying PGK1p-ILV2 and PGK1p-ARO10 were used to overexpress ILV2 and ARO10 genes. After 24-h micro-aerobic fermentation, Engi-3 produced 0·556 g l-1 isobutanol, which was 404% and 25·3% greater than isobutanol produced by control Engi-1 and engineered Engi-2, respectively. After 28 h, Engi-4 produced 0·459 g l-1 isobutanol, which was 315% and 3·2% greater than isobutanol produced Engi-1 and Engi-2, respectively. RNA-Seq-based transcriptome analysis shows that mutations of Spt15 in strain spt15-3 increased the expression of SPT15. Meanwhile, compared with strain Engi-3, the spt15-3 mutation downregulated the expression of genes involved in the TCA cycle and glyoxylic acid cycle, but increased the expression of genes related to cell stability. This work demonstrates that isobutanol tolerance and production of S. cerevisiae can be improved by engineering its TATA-binding protein Spt15. This study clarified the molecular mechanisms regulating isobutanol production and tolerance in S. cerevisiae.

Abstract
OBJECTIVE The aim of this study was to investigate the roles of micro ribonucleic acid (miR)-199a in rats with cerebral infarction by regulating mammalian target of rapamycin (mTOR). MATERIALS AND METHODS A total of 36 Sprague-Dawley rats were randomly assigned into three groups, including: sham group (n=12), model group (n=12) and miR-199a mimics group (n=12). In sham group internal and external carotid arteries were exposed. The ischemia-reperfusion model was successfully established using suture embolization in the other two groups. After modeling, rats in sham group and model group were intraperitoneally injected with normal saline. However, rats in miR-199a mimics group were injected with miR-199a mimics. Following intervention for 3 d, sampling was conducted. Neurological deficit was evaluated in rats based on the Zea-Longa scoring system. Hematoxylin-eosin (HE) staining was performed to observe neuronal morphology. The expression of mTOR was detected using immunohistochemistry, and the relative expression level of tau protein was determined via Western blotting (WB). Besides, the messenger RNA (mRNA) expressions of mTOR and tau were detected by quantitative Polymerase Chain Reaction (qPCR). Finally, inflammatory factor content was measured through enzyme-linked immunosorbent assay (ELISA). RESULTS Model group and miR-199a mimics group exhibited a substantially higher Zea-Longa score than sham group (p<0.05). Compared with model group, the Zea-Longa score rose prominently in miR-199a mimics group (p<0.05). According to the results of HE staining, the structure of neurons in sham group was clear and intact, while the structure of neurons in model group was disordered. Meanwhile, neuronal morphology in miR-199a mimics group was significantly worse than that in model group (p<0.05). Immunohistochemistry results demonstrated that the positive expression level of mTOR was considerably upregulated in both model group and miR-199a mimics group in comparison with sham group (p<0.05). Moreover, its positive expression level in miR-199a mimics group was markedly higher that in model group (p<0.05). Based on the results of WB, model and miR-199a mimics groups exhibited a remarkably higher relative expression level of tau protein than sham group (p<0.05). However, the relative expression level of tau protein in miR-199a mimics group was prominently higher than that in model group (p<0.05). QPCR results manifested that the relative mRNA expression levels of mTOR and tau in model group and miR-199a mimics group were dramatically higher than those in sham group (p<0.05). Compared with those in model group, the relative mRNA expression levels of mTOR and tau increased significantly in miR-199a mimics group (p<0.05). ELISA results revealed that model group and miR-199a mimics group had prominently higher content of inflammatory factors than sham group (p<0.05). In addition, content of inflammatory factors in miR-199a mimics group was considerably higher than that in model group (p<0.05). CONCLUSIONS MiR-199a modulates mTOR expression to exert important regulatory effects on the autophagy and inflammation in rats with cerebral infarction.

Abstract
Doping porous carbon materials with heteroatoms is an effective approach to enhance the performance in the areas of supercapacitors and the oxygen reduction reaction (ORR). However, most traditional heteroatom-doped metal-free porous carbon materials have random structures and pore distributions with high uncertainty, which is harmful for a deep understanding of supercapacitors and the ORR mechanism. Basing on the molecular design, a series of N, O co-doped porous carbon frameworks (p-PYPZs) has been prepared through the template-free trimerization of cyano groups from our designed and synthesized 2,8-bis(4-isocyanophenyl)-2,3,7,8-tetrahydropyridazino[4,5-g]phthalazine-1,4,6,9-tetraone (PYPZ) monomer and subsequent ionothermal synthesis, which has the advantage that the type, position, content of the heteroatom and the pore structure in the porous carbon material can be regulated. Nitrogen and oxygen atoms introduced via covalent bond and the hierarchically porous structure endow the material with excellent cycling stability, and 110% capacitance retention after 35 000 cycles in 1 M H2SO4. A symmetric supercapacitor was assembled with the material and shows an energy density of 32 W h kg-1. The material can be applied to the area of oxygen reduction reaction as a metal-free catalyst with an onset potential of 0.85 V versus RHE, indicating the good catalytic ability. The material exhibits excellent methanol crossover resistance and a four-electron pathway mechanism. Results also indicate a positive correlation between the N-Q content and the selectivity of the four-electron pathway. In this paper, the electrochemical properties of materials are regulated at the molecular level, which provides a new idea for further understanding the electrochemical mechanism of energy storage devices.

Abstract
Rational and purposeful designs of amorphous materials with desirable structures are difficult to implement due to the complex and unordered nature of such materials. In this work, a modelling algorithm was proposed for amorphous covalent triazine-based polymers to construct atomistic representative models that can reproduce the experimentally measured properties of experimental samples. The constructed models were examined through comparisons of simulated and experimental properties, such as surface area, pore volume, and structure factor, and further validated by the good consistency observed among these properties. To assess the predictive capability of the modelling algorithm, we used a new covalent triazine-based polymer and predicted its porosity by constructing a simulated model. The predicted results on the surface area and pore volume of the simulated model were quantitatively consistent with the experimental data derived from the experimentally synthesized sample. This consistency reveals the predictive capacity of the proposed modelling algorithm. The algorithm could be a promising approach to predict and develop advanced covalent triazine-based polymers for multiple applications.

Abstract
Objective: To investigate the effect of 6% hydroxyethyl starch 130/0.4(HES) on protein in severe trauma orthopedic patients after acute hemodilution. Methods: Fourty-eight severe trauma patients who met the inclusion criteria were selected from June 2018 to December 2018 in Yantaishan Hospital, and were randomly divided into two groups (n=24): group A and group B. Group A was ringer's sodium lactate control group, and group B was HES treatment group. After the tracheal intubation, the patients of group A were infused with 10% blood volume of sodium lactate ringer at 0.5 ml·kg(-1)·min(-1), and the patients in group B were infused with 10% blood volume of HES at 0.5 ml·kg(-1)·min(-1). Total protein (TP), human serum albumin (HSA), numbers of circulating endothelium cells (CEC), C-reactive protein (CRP), and serum levels of tumor necrosis factor-alpha (TNF-α), interleukin (IL)-10 and IL-6 were measured immediately after acute hemodilution (T(0)), 24 hours (T(1)) and 48 hours (T(2)) after acute hemodilution. After infusion into human body, HES bond to HSA, and fluorescence spectroscopy was used to analyze the binding relationship between HES and HSA in order to further study the effects of HES on HSA. Results: The HSA, TP, CEC, TNF-α, IL-6, IL-10, CRP at T(0) of group A were (38±5) g/L, (66±5) g/L, (5.5±0.4)/0.9 μl, (24±5) μg/L, (8.9±0.8) μg/L, (44±6) μg/L, (13.6±1.4) mg/L; While at T(1) were (33±5) g/L, (60±6) g/L, (10.2±0.7)/0.9 μl, (87±9) μg/L, (38.8±2.3) μg/L, (57±7) μg/L, (23.4±2.4) mg/L. The HSA, TP, CEC, TNF-α, IL-6, IL-10, CRP at T(0) of group B were(38±4)g/L, (66±5) g/L, (5.4±0.6)/0.9 μl, (24±6) μg/L, (9.1±0.9) μg/L, (45±6) μg/L, (13.4±1.8) mg/L; While at T(1) were (35±5)g/L, (62±5)g/L, (7.4±0.6)/0.9 μl, (70±8) μg/L, (29.5±3.1) μg/L, (72±6) μg/L, (19.7±2.2) mg/L. HSA and TP decreased at T(1) in group A as compared with T(0) (P<0.05), contrarily CEC increased significantly at T(1), TNF-ɑ, IL-6, IL-10 and CRP augmented at T(1) and T(2) in two groups (P<0.05). In comparison with the patients of group A, CEC decreased significantly at T(1) (P<0.05). TNF-ɑ, IL-6, CRP reduced significantly at T(1) and T(2) (P<0.05), but IL-10 increased at T(1) and T(2) in group B (P<0.05). The secondary structure of HSA changed after HES was added in the HES solution. The fluorescence intensity of HSA decreased with the increase of HES concentration,which suggested that HES induced HSA fluorescence quenching. HES could bind to Trp-214 residue in HSA at a molecular ration of 1∶1. Conclusions: 6% HES reduces the occurrence of low protein level in severe trauma patients after operation. HES could bind to Trp-214 amino acid residue in HSA and form the complex at a molecular ratio of 1∶1. The formation of HES-HSA complex increases the volume of HES, avoids the vascular leakage, protects the vascular endothelial cells, and induces anti-inflammatory immunity in the patients with capillary syndrome.

Abstract
2D MXenes are attractive for energy storage applications because of their high electronic conductivity. However, it is still highly challenging for improving the sluggish sodium (Na)-ion transport kinetics within the MXenes interlayers. Herein, a novel nitrogen-doped Ti3C2Tx MXene was synthesized by introducing the in situ polymeric sodium dicyanamide (Na-dca) to tune the complex terminations and then utilized as intercalation-type pseudocapacitive anode of Na-ion capacitors (NICs). The Na-dca can intercalate into the interlayers of Ti3C2Tx nanosheets and simultaneously form sodium tricyanomelaminate (Na3TCM) by the catalyst-free trimerization. The as-prepared Ti3C2Tx/Na3TCM exhibits a high N-doping of 5.6 at.% in the form of strong Ti-N bonding and stabilized triazine ring structure. Consequently, coupling Ti3C2Tx/Na3TCM anode with different mass of activated carbon cathodes, the asymmetric MXene//carbon NICs are assembled. It is able to deliver high energy density (97.6 Wh kg-1), high power output (16.5 kW kg-1), and excellent cycling stability (≈ 82.6% capacitance retention after 8000 cycles).

Abstract
Glutamine addiction is a major feature of glioma cells and plays an important role in its growth and proliferation. GLUL (glutamate-ammonia ligase), which catalyzes glutamate and ammonia to synthesize glutamine, plays a crucial role in tumor growth and proliferation. We attempt to determine a pathway that limits the growth of glioma by targeting GLUL and explore effective strategies blocking glutamine metabolism. We note that miRNAs mediate regulation of genes participating directly or indirectly in cancer cell metabolism. The regulatory roles of miRNAs on metabolic enzymes are widely discussed, however miRNAs regulation of glutamine metabolism by targeting GLUL in glioma has not yet been reported. Here, we examined both the expression and functions of GLUL in glioma cells. Findings indicated that the expression of GLUL was upregulated in high-grade compared to low-grade glioma cells. Knockdown of GLUL effectively inhibited proliferation, migration and invasion of glioma cells in vitro. Bioinformatics analyses, as well as dual-luciferase reporter assays, revealed that miR-140-5p bound to GLUL mRNA at the 3'-UTR location. Furthermore, the proliferation, migration and invasion of glioma cells were also repressed by miR-140-5p. Overall, these results showed that miR-140-5p exerted its inhibitory effects on proliferation, migration and invasion in glioma cells through downregulating GLUL. Thus, the miR-140-5p/GLUL axis may function as a potential target for glioma treatment.

Abstract
OBJECTIVE To investigate the influences of remifentanil on myocardial ischemia-reperfusion injury in rats and the expressions of b-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax) and other apoptosis-related proteins. MATERIALS AND METHODS A total of 60 Sprague-Dawley (SD) rats were randomly divided into sham operation (S) group, model (M) group, low-dose remifentanil (L) group and high-dose remifentanil (H) group, with 15 rats in each group. The rat model of myocardial ischemia-reperfusion injury was established by the ligation of the left anterior descending branch (LAD). After ischemia for 30 min and reperfusion for 24 h, the cardiac function of rats in each group was measured by an ultrasonic instrument. Triphenyl tetrazolium chloride (TTC) staining was used to detect the myocardial infarction area of rats in each group. The activity of myocardial enzymes in the serum of rats in each group was detected. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining was adopted to examine the apoptosis level of rat cardiomyocytes in each group. Quantitative polymerase chain reaction (qPCR) and Western blotting were applied to detect the expression levels of apoptosis-related proteins and messenger ribonucleic acids (mRNAs) in rat cardiomyocytes in each group. RESULTS Compared with those in S group, left ventricular internal dimension in systole (LVIDs) and left ventricular internal dimension in diastole (LVIDd) were markedly increased (p<0.01), while left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were notably decreased in M group (p<0.01). LVIDs and LVIDd in L group and H group were lower than those in M group (p<0.05, p<0.01), whereas LVEF and LVFS were higher than those in M group (p<0.05, p<0.01). The myocardial infarction area in M group was significantly larger than that in S group (p<0.01), and those in L group and H group were remarkably smaller than that in M group (p<0.05, p<0.01). The activities of aspartate aminotransferase (AST), lactate dehydrogenase (LDH) and creatine kinase-muscle/brain (CK-MB) in the serum of rats in M group were evidently higher than those in S group (p<0.01), and compared with those in M group, those in L group and H group were significantly decreased (p<0.05, p<0.01). The apoptosis level of myocardial cells in M group was significantly higher than that in S group (p<0.01), while those in L group and H group were markedly lower than that in M group (p<0.05, p<0.01). Compared with those in S group, the expression levels of cleaved caspase-3 and its mRNAs in myocardial cells in M group were remarkably increased (p<0.01), while those of Bcl-2/Bax and it mRNAs were significantly decreased (p<0.01). The expression levels of cleaved caspase-3 and its mRNAs in myocardial cells in L group and H group were significantly lower than those in M group (p<0.05, p<0.01), but those of Bcl-2/Bax and its mRNAs were significantly higher than those in M group (p<0.05, p<0.01). CONCLUSIONS Remifentanil can effectively reduce myocardial cell injury caused by myocardial ischemia-reperfusion in rats, improve cardiac function, reduce the myocardial infarction area, decrease cleaved caspase-3 in myocardial cells, and increase Bcl-2/Bax.

Abstract
The structures of amorphous materials are generally difficult to characterize and comprehend due to their unordered nature and indirect measurement techniques. However, molecular simulation has been considered as an alternative method that can provide molecular-level information supplementary to experimental techniques. In this work, a new approach for modelling the atomistic structures of amorphous covalent triazine-based polymers is proposed and employed on two experimentally synthesized covalent triazine-based polymers. To examine the proposed modelling approach, the properties of the established models, such as surface areas, pore volumes, structure factors and N2 adsorption isotherms, were calculated and compared with the experimental data. Excellent consistencies were observed between the simulated models and experimental samples, consequently validating the proposed models and the modelling approach. Moreover, the proposed modelling approach can be applied to new covalent triazine-based polymers for predictive purposes and to provide design strategies for future synthesis works. A well-established modelling approach to construct and predict the structures of amorphous covalent triazine-based polymers is proposed.![]()

Abstract
Integrin β4 (ITGB4) has been shown to play an important role in the regulation of cancer stem cells (CSC). Immune targeting of ITGB4 represents a novel approach to target this cell population, with potential clinical benefit. We developed two immunologic strategies to target ITGB4: ITGB4 protein-pulsed dendritic cells (ITGB4-DC) for vaccination and adoptive transfer of anti-CD3/anti-ITGB4 bispecific antibody (ITGB4 BiAb)-armed tumor-draining lymph node T cells. Two immunocompetent mouse models were utilized to assess the efficacy of these immunotherapies in targeting both CSCs and bulk tumor populations: 4T1 mammary tumors and SCC7 head and neck squamous carcinoma cell line. Immunologic targeting of ITGB4 utilizing either ITGB4-DC or ITGB4 BiAb-T cells significantly inhibited local tumor growth and metastases in both the 4T1 and SCC7 tumor models. Furthermore, the efficacy of both of these ITGB4-targeted immunotherapies was significantly enhanced by the addition of anti-PD-L1. Both ITGB4-targeted immunotherapies induced endogenous T-cell cytotoxicity directed at CSCs as well as non-CSCs, which expressed ITGB4, and immune plasma-mediated killing of CSCs. As a result, ITGB4-targeted immunotherapy reduced not only the number of ITGB4high CSCs in residual 4T1 and SCC7 tumors but also their tumor-initiating capacity in secondary mouse implants. In addition, treated mice demonstrated no apparent toxicity. The specificity of these treatments was demonstrated by the lack of effects observed using ITGB4 knockout 4T1 or ITGB4-negative CT26 colon carcinoma cells. Because ITGB4 is expressed by CSCs across a variety of tumor types, these results support immunologic targeting of ITGB4 as a promising therapeutic strategy.Significance: This study identifies a novel mechanism of resistance to anti-PD-1/PD-L1 immunotherapy mediated by HPV E5, which can be exploited using the HPV E5 inhibitor rimantadine to improve outcomes for head and neck cancer patients.

Abstract
HIV persistence during combination antiretroviral therapy (cART) is the principal obstacle to cure. Mechanisms responsible for persistence remain uncertain; infections may be maintained by persistence and clonal expansion of infected cells or by ongoing replication in anatomic locations with poor antiretroviral penetration. These mechanisms require different strategies for eradication, and determining their contributions to HIV persistence is essential. We used phylogenetic approaches to investigate, at the DNA level, HIV populations in blood, lymphoid, and other infected tissues obtained at colonoscopy or autopsy in individuals who were on cART for 8 to 16 years. We found no evidence of ongoing replication or compartmentalization of HIV; we did detect clonal expansion of infected cells that were present before cART. Long-term persistence, and not ongoing replication, is primarily responsible for maintaining HIV. HIV-infected cells present when cART is initiated represent the only identifiable source of persistence and is the appropriate focus for eradication.

Abstract
BACKGROUND Mediastinal restaging after induction treatment is still a difficult and controversial issue. We aimed to investigate the diagnostic accuracy of endobronchial ultrasound-guided transbronchial needle aspiration and endoscopic ultrasound-guided fine-needle aspiration for restaging the mediastinum after induction treatment in patients with lung cancer. METHODS Embase and PubMed databases were searched from conception to March 2019. Data from relevant studies were analyzed to assess sensitivity and specificity of endobronchial ultrasound-guided transbronchial needle aspiration and endoscopic ultrasound-guided fine-needle aspiration, and to fit the hierarchical summary receiver operating characteristic curves. RESULTS A total of 10 studies consisting of 558 patients fulfilled the inclusion criteria. All patients were restaged by endobronchial ultrasound-guided transbronchial needle aspiration, endoscopic ultrasound-guided fine-needle aspiration, or both. Negative results were confirmed by subsequent surgical approaches. There were no complications reported during any endosonography approaches reviewed. The pooled sensitivities of endobronchial ultrasound-guided transbronchial needle aspiration and endoscopic ultrasound-guided fine-needle aspiration were 65% (95% confidence interval [CI], 52-76) and 73% (95% CI, 52-87), respectively, and specificities were 99% (95% CI, 78-100) and 99% (95% CI, 90-100), respectively. The area under the hierarchical summary receiver operating characteristic curves were 0.85 (95% CI, 0.81-0.88) for endobronchial ultrasound-guided transbronchial needle aspiration and 0.99 (95% CI, 0.98-1) for endoscopic ultrasound-guided fine-needle aspiration. Moreover, for patients who received chemotherapy alone, the pooled sensitivity of endosonography with lymph node sampling for restaging was 66% (95% CI, 56-75), and specificity was 100% (95% CI, 34-100); for patients who received chemoradiotherapy, the results seemed similar with a sensitivity of 77% (95% CI, 47-92) and specificity of 99% (95% CI, 48-100). CONCLUSIONS Endosonography with lymph node sampling is an accurate and safe technique for mediastinal restaging of lung cancer.

Abstract
Recently, microalgae cultivation for different applications, including the production of nutritional and pharmaceutical active compounds has received increasing attention. Among the different genera, Spirulina (Arthrospira sp.) is one of the most promising blue-green microalgae (Cyanophyta) because it is rich in antioxidants, essential amino acids (EAAs), minerals, proteins, polyunsaturated fatty acids and vitamins. It has a high protein content (60-70% of the dry weight), which is a complete protein, i.e. containing all EAAs. Therefore, Spirulina is currently a commercial product with high nutritional value and also a significant source of complementary and alternative medicine. The objective of the present work was to review the pharmaceutical and therapeutic applications of Spirulina, especially its antioxidant, anti-inflammatory, anti-cancer, anti-microbial, anti-diabetic, anti-obesity and anti-toxicity properties. The results were obtained from experiments in the literature performed in vitro and in vivo using experimental animals. The main reported active ingredients in Spirulina include phycocyanin, tocopherol, β-carotene, caffeic acids and chlorogenic acid, which showed individual or synergetic effects. In addition, the present review discusses the future perspectives of genetically modified Spirulina as a source for industrial products while producing valuable biomass photoautotrophically. Furthermore, the consequent environmental impacts of large-scale cultivation of Spirulina are discussed.

Abstract
BACKGROUND AND PURPOSE Subjective memory impairment (SMI) and amnestic mild cognitive impairment (aMCI) are thought to represent the pre-dementia stages of Alzheimer's disease (AD). SMI is considered a more advanced pre-clinical status prior to aMCI. Understanding the neuromechanism of SMI will have great benefits for monitoring the disease progression of AD. The study aims to explore whether SMI shows alterations of white matter (WM) integrity similar to the patterns of aMCI. METHODS The atlas-based analyses were performed to investigate the diffusion changes in the major WM tracts amongst 22 individuals with normal cognition (NC), 22 SMI patients and 25 aMCI patients. The correlations between the altered diffusion metrics and cognitive performance in the SMI and aMCI groups were assessed. RESULTS The diffusion tensor metrics of SMI were intermediate between the NC and aMCI groups. The aMCI group presented disrupted integrity in multiple WM tracts, including the left anterior thalamic radiation, right corticospinal tract and left cingulum of the hippocampus (CgH), compared to the NC group. The left CgH showed diffusion alterations in the SMI group. In the aMCI group, the mean diffusivity of the left CgH was negatively correlated with episodic memory, whilst the radial diffusivity of the right corticospinal tract was negatively correlated with executive function. No significant relationship was found in the SMI group. CONCLUSION The study suggested that SMI patients might present detectable WM integrity changes in the left CgH before exhibiting objective cognitive dysfunction, which may provide novel insights into the pathological mechanisms of AD.

Abstract
Woody breast meat has recently become prevalent in the broiler industry in both the United States and European Union. Recent publications have described the meat quality characteristics of woody breast meat as having hardened areas and pale ridge-like bulges at both the caudal and cranial regions of the breast. The present study investigated the meat quality (pH, color, cooking loss, and shear force) and protein quality characteristics (protein and salt-soluble protein content) in woody breast meat as compared to normal breast meat. In addition, the differences in the muscle proteome profiles of woody and normal breast meat were characterized. Results indicated that woody breast meat had a greater average pH (P < 0.0001) and cooking loss (P = 0.001) than normal breast meat, but woody breast meat did not differ in shear force (P > 0.05) in comparison to normal breast meat samples. The L*, a*, and b* values of woody breast fillets were greater than normal breast fillets (P < 0.0001 to L*; P = 0.002 to a*; P = 0.016 to b*). The woody breast meat had more fat (P < 0.0001) and moisture (P < 0.021) and less protein (P < 0.0001) and salt-soluble protein (P < 0.0001) when compared with normal breast fillets. Whole muscle proteome analysis indicated 8 proteins that were differentially expressed (P < 0.05) between normal and woody breast meat samples. The differences in muscle proteome between normal and woody breast meat indicated an increased oxidative stress in woody breast meat when compared to normal meat. In addition, the abundance of some glycolytic enzymes, which are critical to the regeneration of adenosine triphosphate (ATP) in postmortem muscles, was lower in woody breast meat than in normal breast meat. Proteomic differences provide additional information on the biochemical pathways and genetic variations that lead to woody breast meat. Further research should be conducted to elucidate the genetic and nutritional contributions to the proliferation of woody breast meat in the United States.

Abstract
The conventional two-dimensional (2D) and glasses-assisted three-dimensional (3D) display systems can no longer meet the clinical requirements with the development of minimally invasive video-assisted thoracoscopic surgery (VATS). The glasses-free 3D display technology adopts both lenticular lens technology and face-tracking and -positioning systems and offers high brightness, large viewing area, and strong anti-interference capability, which significantly improve the operator's experience. When applied in VATS, it has many advantages including good display depth, convenience for performing complex and fine operations, and short learning curve. This novel display technology will greatly promote the development of minimally invasive surgery.

Abstract
OBJECTIVE To investigate the efficacy of inhalational sevoflurane anesthesia induction on inhibiting the stress response to endotracheal intubation in pediatric patients with congenital heart disease (CHD). PATIENTS AND METHODS Forty ASA physical status I/II pediatric patients scheduled for interventricular septal defect repair or interatrial septal defect repair, were randomly divided into two groups (20 each): intravenous induction group (Group C) and inhalational sevoflurane anesthesia induction group (Group D). In group C, anesthesia was induced with midazolam, pipecuronium bromide and fentanyl, and the children were examined by radial artery monitoring after the consciousness extinction. Also, they were endotracheally intubated after muscle relaxation. In group D, anesthesia was induced with inhalation of 8% sevoflurane and 6 L/min oxygen, and the children were examined by radial artery monitoring after the consciousness extinction and were endotracheally intubated 4 min later. Before anesthesia induction (T0), consciousness extinction (T1), endotracheal intubation (T2), endotracheal intubation (T3), and after endotracheal intubation (T4), 1 and 3 min after intratracheal intubation (T5,6), HR and bispectral index (BIS) were monitored. The MAP of T2-T6 points was recorded. Ulnar vein blood samples were taken for determination of Endothelin (ET) and Thromboxane A2(TXA2) in the points of consciousness extinction, and 5 and 10 min after endotracheal. RESULTS All the children were well examined by endotracheal intubation. Compared with the baseline value at T0, there was no significant difference of HR in group D, but the HR of group C was decreased at T2, T3, T4 and T6. The BIS of the two groups were decreased at T1-T6 (p<0.05). Compared with the values at T2, they were increased at T5 and T6 in group C, and increased at T6 in group D (p<0.05). Compared with group C, the MAP of group D was decreased at T5, and the BIS of the two groups was decreased at T2-T6 (p<0.05). There were no significant differences of ET and TXA2 between groups. CONCLUSIONS It is well inhibited the endotracheal intubation stress response in children with congenital heart diseases using sevoflurane inhalational anesthesia induction.

Abstract
OBJECTIVES The investigation was aimed to evaluate the safety and efficacy of glasses-free 3-dimensional (3D) video-assisted thoracoscopic surgery (VATS) versus 2D VATS for radical resection of non-small cell lung cancer (NSCLC). METHODS We reviewed the clinical data of patients with pathologically proven NSCLC who underwent glasses-free 3D (the 3D group) and 2D VATS radical lobectomy (the 2D group) with systematic lymph node dissection. The outcomes of this study included operative characteristics and safety of 2D and 3D VATS, and duration of lymphadenectomy of right stations 2 and 4. RESULTS A total of 190 patients were eligible for the study. The 2D group consisted of 108 patients while the 3D group included 82 patients. The 2 groups were comparable in demographic and baseline variables ( P > .05). The median number of resected lymph nodes was 19 in both groups ( P = .583). The median length of hospital stay was comparable between the 2 groups (2D, 7 days vs 3D, 8 days; P = .167). No operative mortality was reported in either group. Complications developed in 21 (19.4%) patients in the 2D group and 14 (17.1%) in the 3D group ( P = .710). A subgroup analysis of patients who underwent right station 2 and 4 lymphadenectomy showed that the mean time for right station 2 and 4 lymph node dissection was significantly shorter in the 3D group than in the 2D group (3D, 430.9 ± 237.2 vs 2D, 648.6 ± 364.1 seconds; P < .001). CONCLUSIONS Glasses-free 3D VATS and 2D VATS are comparable in operative characteristics and safety profile for radical resection of NSCLC. Glasses-free 3D visualization facilitates more rapid right-sided mediastinal lymphadenectomy.

Abstract
Tumor metastasis is the main reason for the poor prognosis of lung cancer patients. The GABAA receptor subunit GABRA3 is reportedly upregulated in lung cancer. Herein, we show that high GABRA3 protein expression in lung adenocarcinoma correlated positively with disease stage, lymphatic metastasis status and poor patient survival. In addition, GABRA3 induced MMP-2 and MMP-9 expression through activation of the JNK/AP-1 signaling pathway, which enhanced lymphatic metastasis by lung adenocarcinoma both in vitro and in vivo. These results indicate that GABRA3 promotes lymph node metastasis and may thus be an effective therapeutic target for anticancer treatment.

Abstract
OBJECTIVES Myasthenia gravis (MG) benefits from thymectomy. However, its unpredictable response to muscle relaxants and volatile anesthetic agents may result in muscle weakness and subsequently in postoperative myasthenic crisis. The aim of this study was to determine the surgical outcomes after spontaneous ventilation compared with conventional intubated video-assisted thoracoscopic thymectomy (spontaneous-ventilation video-assisted thoracic thymectomy [SV-VATT] vs intubated video-assisted thoracic thymectomy) in patients with MG. METHODS Data from all minimally invasive thymectomy procedures performed at our institute between January 2009 and June 2016 were collected. Patient characteristics, perioperative results, and treatment outcomes between SV-VATT (group 1) and the intubated video-assisted thoracic thymectomy (group 2) groups were compared. Furthermore, a propensity score-matching analysis was generated to control for selection bias due to nonrandom group assignment in a 1:1 manner. RESULTS Thirty-six patients were included in group 1 and 68 in group 2. Matching of patients according to propensity score resulted in a cohort that consisted of 27 patients in both groups. Patients had similar clinical characteristics in both groups. Operating time (P = .07) and lowest pulse oxygen saturation (P = .09) between the procedures were comparable after matching, but peak CO2 level at the end of expiration was significantly greater in group 1 both before and after matching (P < .01). Moreover, the incidence of postoperative myasthenic crisis and postoperative prolonged tracheal intubation was lower in group 1. The postoperative pain visual analog scale score (P < .01) and the length of hospital stay (P = .03) were shorter in group 1. CONCLUSIONS SV-VATT is a feasible procedure in patients with MG. It might be beneficial by reducing postoperative myasthenic crisis and postoperative prolonged tracheal intubation. Further prospective research is needed.

Abstract
A series of multiheteroatom porous carbon frameworks (MPCFs) is prepared successfully from the trimerization of cyano groups of our designed and synthesized 4,4'-(4-oxophthalazine-1,3(4H)-diyl)dibenzonitrile monomers and subsequent ionothermal synthesis. Benefiting from the molecular engineering strategy, the obtained MPCFs framework show a homogeneous distribution of nitrogen and oxygen heteroatoms at the atomic level, confirmed by the transmission electron microscopy mapping intuitively, thereby ensuring the stability of electrical properties. The supercapacitor with the obtained MPCFs@700 as the electrode exhibits a high energy density of 65 Wh kg-1 at 0.1 A g-1, with excellent long cycle life and cycle stability (98% capacitance retention for 10 000 cycles in 1-butyl-3-methylimidazolium tetrafluoroborate). Another two electrolyte systems employed also demonstrate the delightful results, showing a 112% capacitance retention for 30 000 cycles in 1 M H2SO4 and a 95% capacitance retention for 30 000 cycles in tetraethylammonium tetrafluoroborate in an acetonitrile solution. Moreover, the successful preparation of MPCFs provides new insights into the fabrication of electrode materials intrinsically containing nitrogen and oxygen in the frameworks for readily available components through a facile routine.

Abstract
The push for minimally invasive techniques had led to the development of many surgical tools and the innovation and completion of ever more complex operations. To achieve faster postoperative recovery of patients, we have been dedicated to the development of surgical skills that have allowed us to successfully complete many procedures under video-assisted thoracoscopic surgery (VATS) that are complex even with open approach. Specifically, sleeve, trachea, and carina resections and reconstructions using either general or spontaneous respiration anesthesia (SRA) techniques. Our long term high volume thoracic experience has equipped us with a talented multidisciplinary team with the ability to confidently and safely perform many types of complicated VATS procedures.
