Consecutive critically ill AECOPD patients receiving treatment in a respiratory intensive care unit were reviewed from September 1, 2012, to August 31, 2015. Categorical variables were analyzed using chi-square tests, and continuous variables were analyzed by Mann–Whitney U-test. Kaplan–Meier analysis was used to assess the association of CAP with survival of critically ill AECOPD patients for univariate analysis. Cox’s proportional hazards regression model was performed to identify risk factors for multivariate analysis.Results: A total of 80 consecutive eligible individuals were reviewed. These included 38 patients with CAP and 42 patients without CAP. Patients with CAP had a higher inhospital rate of mortality than patients without CAP (42% vs 33.3%, P

Edaravone Dexborneol (EDB), comprised of edaravone and (+)- bornel, has been demonstrated to have synergistic effects of antioxidant and anti-inflammatory, which makes it to be applied for stroke as a protectant. However, the underlying mechanism of neuroprotection of EDB has not been fully elucidated. Increasing evidence has shown that neurotoxic A1 astrocytes were closely related to neuronal death after cerebral ischemia. However, whether EDB could provide neuroprotection by modulating the activation of astrocytes has not yet been elucidated. The present study aimed to explore whether EDB afforded neuroprotection by modulating A1 polarization of astrocytes and the down-stream signaling after cerebral ischemia. We first validated the neuroprotective effects of EDB in mice suffering focal cerebral ischemia via evaluating behavioral test, infarct volumes and neuronal survival. As for the down-stream signaling, our data further showed that EDB alleviated neuronal death by suppressing activation of neurotoxic A1 astrocytes via inhibition of NF-κB signaling pathway in vitro. Additionally, administration of EDB reduced the number of A1 reactive astrocytes in mice of focal cerebral ischemia. The above findings demonstrated that EDB provided neuroprotective effect by inhibiting neurotoxic activation of A1 astrocytes in animal model of cerebral ischemia, which indicated that EDB-mediated phenotypic regulation of astrocytes is a potential research direction to promote neurological recovery in central nervous system (CNS) diseases., Competing Interests: Declaration of Competing Interest All authors declare that there is no conflict of interest., (Copyright © 2024 The Authors.

Solid-state sodium metal batteries have been extensively investigated because of their potential to improve safety, cost-effectiveness, and energy density. The development of such batteries urgently required a solid-state electrolyte with fast Na-ion conduction and favorable interfacial compatibility. Herein, the progress on developing the NaB 3 H 8 solid-state electrolytes is reported, which show a liquid-like ionic conductivity of 0.05 S cm -1 at 56 °C with an activation energy of 0.35 eV after an order-disorder phase transformation, matching or surpassing the best single-anion hydridoborate conductors investigated up to now. The steady polarization voltage and significantly decreased resistance are achieved in the symmetric Na/NaB 3 H 8 /Na cell, indicating the great electrochemical stability and favorable interfacial contact with the Na metal of NaB 3 H 8 . Furthermore, a Na/NaB 3 H 8 /TiS 2 battery, the first high-rate (up to 1 C) solid-state sodium metal battery using the single-anion hydridoborate electrolyte, is demonstrated, which exhibits superior rate capability (168.2 mAh g -1 at 0.1 C and 141.2 mAh g -1 at 1 C) and long-term cycling stability (70.9% capacity retention at 1 C after 300 cycles) at 30 °C. This work may present a new possibility to solve the interfacial limitations and find a new group of solid-state electrolytes for high-performance sodium metal batteries., (© 2024 Wiley‐VCH GmbH.)

Background: Extralobar pulmonary sequestration (ELS) with torsion is extremely rare, consequently, the diagnosis of ELS with torsion in children presents a challenge for clinicians. Herein, we report four cases of ELS with torsion that presented with abdominal pain, and further review the relevant literature to summarize the clinical features., Case Summary: Four children presented to our department with abdominal pain. All underwent chest computed tomography, which revealed an intrathoracic soft tissue mass with pleural effusion. All four children underwent thoracoscopic resection of the identified pulmonary sequestration, and the vascular pedicle was clipped and excised. None of the patients experienced any postoperative complications., Conclusion: Clinicians should consider the possibility of ELS with torsion in children presenting with abdominal pain as the chief complaint., Competing Interests: Conflict-of-interest statement: All authors declare that they have no conflicts of interest to disclose., (©The Author(s) 2024.

Background: Recent studies have shown an association between trace elements and systemic lupus erythematosus (SLE), but the relationship between trace elements and SLE is still unclear. This study aims to determine the distribution of plasma trace elements in newly diagnosed SLE patients and the association between these essential and toxic element mixtures and SLE., Methods: In total, 110 SLE patients and 110 healthy controls were included. Blood samples were collected. 15 plasma trace elements were quantified using an inductively coupled plasma mass spectrometer (ICP-MS). Multivariate logistic regression, restricted cubic spline (RCS), weighted quantile sum (WQS) regression, quantile g-computation (qgcomp), and Bayesian kernel machine regression (BKMR) are used to analyze the association between single and mixed exposure of elements and SLE., Results: The logistic regression model shows that, plasma lithium (Li) [OR (95 % CI): 1.963 (1.49-2.586)], vanadium (V) [OR (95 % CI): 2.617(1.645-4.166)] and lead (Pb) [OR (95 % CI): 1.603(1.197-2.145)] were positively correlated with SLE, while selenium (Se) [OR (95 % CI): 0.055(0.019-0.157)] and barium (Ba) [OR (95 % CI): 0.792(0.656-0.957)] had been identified as protective factors for SLE. RCS results showed a non-linear correlation between the elements Li, V, Ni, copper, Se, rubidium and SLE. In addition, WQS regression, qgcomp, and BKMR models consistently revealed significant positive effects of plasma Li and Pb on SLE, as well as significant negative effects of plasma Se., Conclusions: Exposure to heavy metals such as Li and Pb is significantly positively correlated with SLE, but Se may be protective factors for SLE. In addition, there is a nonlinear correlation between the elements Li and Se and SLE, and there are complex interactions between the elements. In the future, larger populations and prospective studies are needed to confirm these associations., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Sterols have long been associated with diverse fields, such as cancer treatment, drug development, and plant growth; however, their underlying mechanisms and functions remain enigmatic. Here, we unveil a critical role played by a GmNF-YC9-mediated CCAAT-box transcription complex in modulating the steroid metabolism pathway within soybeans. Specifically, this complex directly activates squalene monooxygenase (GmSQE1), which is a rate-limiting enzyme in steroid synthesis. Our findings demonstrate that overexpression of either GmNF-YC9 or GmSQE1 significantly enhances soybean stress tolerance, while the inhibition of SQE weakens this tolerance. Field experiments conducted over two seasons further reveal increased yields per plant in both GmNF-YC9 and GmSQE1 overexpressing plants under drought stress conditions. This enhanced stress tolerance is attributed to the reduction of abiotic stress-induced cell oxidative damage. Transcriptome and metabolome analyses shed light on the upregulation of multiple sterol compounds, including fucosterol and soyasaponin II, in GmNF-YC9 and GmSQE1 overexpressing soybean plants under stress conditions. Intriguingly, the application of soybean steroids, including fucosterol and soyasaponin II, significantly improves drought tolerance in soybean, wheat, foxtail millet, and maize. These findings underscore the pivotal role of soybean steroids in countering oxidative stress in plants and offer a new research strategy for enhancing crop stress tolerance and quality from gene regulation to chemical intervention., (© 2024 The Authors.

Injectable hydrogels, providing sustained release as implanted materials, have received tremendous attention. In this study, chitosan-based hydrogels were prepared via Schiff base reaction of the aldehyde groups on Poly(NIPAM-co-FBEMA) and the amine groups on chitosan. Owing to the dynamic covalent linkage, the SC/PNF hydrogels exhibit pH-responsive, reversible sol-gel transition, injectable, and self-healing capacity. The mechanical strength of SC/PNF hydrogels can be operated simply by switching the composition or solid content of Poly(NIPAM-co-FBEMA) copolymers. Rheological analyses, including frequency sweeps, strain sweep scanning, and dynamic time sweeps, were employed to demonstrate the relationship between storage modulus (G'), loss modulus (G″), and composition of the SC/PNF hydrogels. In vitro release behaviors reveal that vancomycin-loaded SC/PNF hydrogel could contribute to both the initial burst release (over 1000 ppm within 4 h) and the sustained release (3000 ppm for at least 30 days). Pristine SC/PNF hydrogel holds good biocompatibility toward L929 cells and S. aureus that it degrades as incubated with S. aureus. However, vancomycin-wrapped SC/PNF hydrogel possesses a rapid bacterial-killing effect with a clear inhibition zone. In short, the SC/PNF hydrogels deliver not only sustainable release ability but also tunable physical properties, which are expected to be an outstanding candidate for non-invasive, anti-infection applications., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Chih-Yu Kuo reports financial support was provided by National Science and Technology Council.

Objectives: To investigate the causal relationships between pneumoconiosis and rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and gout., Methods: The random-effects inverse variance weighted (IVW) approach was utilized to explore the causal effects of the instrumental variables (IVs). Sensitivity analyses using the MR-Egger and weighted median (WM) methods were did to investigate horizontal pleiotropy. A leave-one-out analysis was used to avoid the bias resulting from single-nucleotide polymorphisms (SNPs)., Results: There was no causal association between pneumoconiosis and SLE, RA or gout in the European population [OR = 1.01, 95% CI: 0.94-1.10, p  = 0.74; OR = 1.00, 95% CI: 0.999-1.000, p  = 0.50; OR = 1.00, 95% CI: 1.000-1.001, p  = 0.55]. Causal relationships were also not found in pneumoconiosis due to asbestos and other mineral fibers and SLE, RA and gout [OR = 1.01, 95% CI: 0.96-1.07, p  = 0.66; OR = 1.00, 95% CI: 1.00-1.00, p  = 0.68; OR = 1.00, 95% CI: 1.00-1.00, p  = 0.20]., Conclusion: Our study suggests that pneumoconiosis may have no causal relationship with the three inflammatory immune diseases., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Du, Lu, Li, Wang, Wu, Huang, Jin, Wang, Wang, Geng and Li.)

Both anaplastic thyroid cancer (ATC) and papillary thyroid cancer (PTC) originate from thyroid follicular epithelial cells, but ATC has a significantly worse prognosis and shows resistance to conventional therapies. However, clinical trials found that immunotherapy works better in ATC than late-stage PTC. Here, we used single-cell RNA sequencing (scRNA-Seq) to generate a single-cell atlas of thyroid cancer. Differences in ATC and PTC tumor microenvironment components (including malignant cells, stromal cells, and immune cells) leading to the polarized prognoses were identified. Intriguingly, we found that CXCL13+ T lymphocytes were enriched in ATC samples and might promote the development of early tertiary lymphoid structure (TLS). Last, murine experiments and scRNA-Seq analysis of a treated patient's tumor demonstrated that famitinib plus anti-PD-1 antibody could advance TLS in thyroid cancer. We displayed the cellular landscape of ATC and PTC, finding that CXCL13+ T cells and early TLS might make ATC more sensitive to immunotherapy.

Using the fusion-evaporation reaction ^{106}Cd(^{58}Ni,4n)^{160}Os and the gas-filled recoil separator SHANS, two new isotopes _{76}^{160}Os and _{74}^{156}W have been identified. The α decay of ^{160}Os, measured with an α-particle energy of 7080(26) keV and a half-life of 201_{-37}^{+58}  μs, is assigned to originate from the ground state. The daughter nucleus ^{156}W is a β^{+} emitter with a half-life of 291_{-61}^{+86}  ms. The newly measured α-decay data allow us to derive α-decay reduced widths (δ^{2}) for the N=84 isotones up to osmium (Z=76), which are found to decrease with increasing atomic number above Z=68. The reduction of δ^{2} is interpreted as evidence for the strengthening of the N=82 shell closure toward the proton drip line, supported by the increase of the neutron-shell gaps predicted in theoretical models.

Background: Despite the high incidence of lateral neck lymph node (LN) metastasis in papillary thyroid cancer (PTC), the management of the lateral neck remains controversial. We aimed to map the draining LNs in the lateral neck using carbon nanoparticles and explore its potential in neck evaluation., Methods: We conducted a multicenter, prospective study in PTC patients who had non-palpable yet suspicious metastatic lateral LNs on ultrasound and/or computed tomography (CT) but could not be confirmed by fine needle aspiration. Carbon nanoparticle suspension was injected peritumorally into the thyroid and modified lateral neck dissection was subsequently performed., Results: A total of 154 patients were enrolled for analysis. And 5,070 lateral LNs were removed, of which 1,079 (21.3%) were dyed. The median of dyed LNs was 6 per case (range, 1-33). The distribution of dyed LNs in neck compartments was IV > III > IIA > IIB/V, independent of tumor size, location, multifocality or microscopic extra-thyroidal extension (ETE). Compared with undyed LNs, the probabilities of metastasis in dyed LNs were significantly increased in compartment III, IV, V, and II-V (III: 29.3% vs. 15.4%, P<0.001; IV: 26.3% vs. 14.5%, P<0.001; V: 16.7% vs. 3.3%, P=0.005; II-V: 26.3% vs. 10.0%, P<0.001). The relative risks of metastasis in dyed LNs compared with undyed LNs were 1.90, 1.82, 5.04 and 2.62 in compartment III, IV, V, and II-V, respectively., Conclusions: It was the first prospective multicenter study to map the lateral neck LNs with carbon nanoparticles, which could help surgeons visualize the suspicious LNs during surgery. Instead of unguided LN biopsy, this method has a potential role in lateral neck assessment for indeterminate lateral LNs in PTC., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-23-222/coif).

Traditional photonuclear reactions primarily excite giant dipole resonances, making the measurement of isovector giant resonances with higher multipolarities a great challenge. In this Letter, the manipulation of collective excitations of different multipole transitions in even-even nuclei via vortex γ photons is investigated. We develop the calculation method for photonuclear cross sections induced by the vortex γ photon beam using the fully self-consistent random-phase approximation plus particle-vibration coupling (RPA+PVC) model based on Skyrme density functional. We find that the electromagnetic transitions with multipolarity J<|m&#95;{γ}| are forbidden for vortex γ photons due to the angular momentum conservation, with m&#95;{γ} being the projection of total angular momentum of γ photon on its propagation direction. For instance, this allows for probing the isovector giant quadrupole resonance without interference from dipole transitions using vortex γ photons with m&#95;{γ}=2. Furthermore, the electromagnetic transition with J=|m&#95;{γ}|+1 vanishes at a specific polar angle. Therefore, the giant resonances with specific multipolarity can be extracted via vortex γ photons. Moreover, the vortex properties of γ photons can be meticulously diagnosed by measuring the nuclear photon-absorption cross section. Our method opens new avenues for photonuclear excitations, generation of coherent γ photon laser and precise detection of vortex particles, and consequently, has significant impact on nuclear physics, nuclear astrophysics and strong laser physics.

Background: Surgery is the primary treatment for locally advanced differentiated thyroid cancer (DTC). However, some locally advanced patients are not candidates for R0/1 resection. There is limited evidence of neoadjuvant treatment in locally advanced DTC. Surufatinib targets multiple kinases, which is efficient, tolerable, and safe in patients with radioiodine-refractory DTC. In addition, surufatinib plus toripalimab (an anti-PD-1 antibody) showed encouraging antitumor activity in advanced solid tumors. This study was designed to evaluate the efficacy and safety of surufatinib plus toripalimab in locally advanced DTC in the neoadjuvant setting., Methods: In this single-arm, phase II study, patients with pathologically confirmed unresectable or borderline resectable DTC were eligible and received a combination of 250 mg of surufatinib (orally daily) with 240 mg of toripalimab (intravenous, every 3 weeks). Treatment continued until satisfied for curative surgery, disease progression, withdrawal of consent, unacceptable toxicity, or investigator decision. Primary endpoint was objective response rate (ORR). Secondary endpoints included R0/1 resection rate, adverse events (AEs), etc. RESULTS: Ten patients were enrolled and received at least 4 cycles of treatment. The ORR was 60%. Nine patients received R0/1 resections after neoadjuvant treatment. The median best percentage change in the sum of the target lesion diameter was 32%. Most adverse events (AEs) were grade 1 or 2., Conclusions: Surufatinib in combination with toripalimab as neoadjuvant therapy for locally advanced DTC was feasible, and the majority of patients achieved R0/1 resection. It represents a new option for locally advanced DTC and needs further investigation., (© 2023. Society of Surgical Oncology.)

Electrocatalytic water splitting powered by sustainable electricity is a crucial approach for the development of new generation green hydrogen technology. Biomass materials are abundant and renewable, and the application of catalysis can increase the value of some biomass waste and turn waste into fortune. Converting economical and resource-rich biomass into carbon-based multicomponent integrated catalysts (MICs) has been considered as one of the most promising ways to obtain inexpensive, renewable and sustainable electrocatalysts in recent years. In this review, recent advances in biomass-derived carbon-based MICs towards electrocatalytic water splitting are summarized, and the existing issues and key aspects in the development of these electrocatalysts are also discussed and prospected. The application of biomass-derived carbon-based materials will bring some new opportunities in the fields of energy, environment, and catalysis, as well as promote the commercialization of new nanocatalysts in the near future., (© 2023 Wiley-VCH GmbH.)

Background: Microcatheter shaping plays a vital role in coil embolization of cerebral aneurysms, while the complicated method and insufficient training opportunities make it difficult for junior neurovascular clinicians to master this technique. In this program, we constructed a novel training method and assessment system for microcatheter shaping in coil embolization of cerebral aneurysms with 3D technique, and evaluated its efficacy for microcatheter shaping training in junior neurovascular clinicians., Methods: Patient-specific models for cerebral aneurysms in different locations and with different morphologies were selected by experienced senior neurovascular clinicians. The solid polylactic acid model and the soft hollow crystal silicone model of intracranial aneurysms were then made separately for shaping reference and assessment in the training course. Twelve residents without prior experience of microcatheter shaping and 25 neurovascular clinicians who have in vivo experience of microcatheter shaping on 3-5 occasions were selected for this training program and randomly divided into the traditional training group and the experimental training group. Four senior neurovascular clinicians assisted and guided the trainees in two groups and evaluated the time and accuracy of microcatheter shaping., Results: Eighteen trainees were assigned to the traditional training group, among which 4 had prior experience in microcatheter shaping. The other 19 were assigned to the experimental training group, including 8 with prior experience. No statistical difference in the distribution of experienced students between the two groups was noted(P = 0.295). After the training session, the shaping time was found shorter in the experimental training group than that in the traditional training group (40.3.5 ± 16.2 s vs. 54.2 ± 16.4 s, P = 0.014), while the shaping score was found higher in the experimental training group than that in the traditional training group (4.4 ± 0.5 vs. 2.6 ± 1.2, P < 0.001). Specifically, for the trainees without prior experience, the experimental training group also showed less time consumption and higher score (Time: 52.7 ± 7.7 vs. 61.5 ± 9.5, P = 0.02; Score 4.1 ± 0.5 vs. 2.3 ± 1.1, P < 0.01). Meanwhile, for the trainees with prior experience, the advantage was noted in shaping score (4.7 ± 0.3 vs. 3.9 ± 0.6, P < 0.01) but not in time consumption (23.3 ± 4.4 vs. 28.5 ± 3.9, P = 0.07)., Conclusion: This training program is quite effective at teaching junior neurovascular physicians the essential surgical abilities required for coiling cerebral aneurysms., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Background: Video-assisted thoracoscopic surgery (VATS) is an approach that is commonly used to resect pulmonary nodules (PNs). However, when these PNs are located behind the scapula, a transscapular access approach is generally required. In this study, the safety, efficacy, and feasibility of preoperative computed tomography (CT)-guided Sens-cure needle (SCN) localization was assessed for PNs located behind the scapula., Methods: From January 2020 - June 2022, a total of 122 PN patients in our hospital underwent preoperative CT-guided SCN localization and subsequent VATS resection, of whom 12 (9.8%) exhibited PNs behind the scapula necessitating a transscapular approach for this localization procedure., Results: This study included 12 patients, each of whom had one PN located behind the scapula. The CT-guided transscapular SCN localization approach was successful in all patients, and no complications near the operative site were observed. The median localization time was 12 min, and 2 (16.7%) and 1 (8.3%) patients respectively developed pneumothorax and pulmonary hemorrhage after the localization procedure was complete. Wedge resection procedures for these PNs achieved technical success in all cases. Four patients were diagnosed with invasive adenocarcinomas and subsequently accepted lobectomy and systematic lymph node dissection. The median VATS duration and the median blood loss was 80 min and 10 mL, respectively. In total, 3, 5, and 4 PNs were respectively diagnosed as benign, mini-invasive adenocarcinomas, and invasive adenocarcinomas., Conclusion: Preoperative CT-guided transscapular SCN localization represents a safe, straightforward, and effective means of localizing PNs present behind the scapula., (© 2023.

Objective: The present study aimed to use bedside ultrasound to evaluate the effects of metoclopramide on gastric motility in patients being treated for trauma in the emergency department. Methods: Fifty patients underwent an ultrasound immediately after attending the emergency department of Zhang Zhou Hospital due to trauma. The patients were randomly divided into two groups: a metoclopramide group (group M, n = 25) and a normal saline group (group S, n = 25). The cross-sectional area (CSA) of the gastric antrum was measured at 0, 30, 60, 90, and 120 min (T = time). The gastric emptying rate (GER, G E R = - A a r e a T n / A a r e a T n - 30 - 1 × 100 ), GER/min (GER divided by the corresponding interval time), gastric content properties, Perlas grade at different time points, T120 gastric volume (GV), and GV per unit of body weight (GV/W) were evaluated. The risk of vomiting, reflux/aspiration, and type of anesthetic treatment were also evaluated. Results: The differences between the two groups in the CSA of the gastric antrum at each time point were statistically significant ( p < 0.001). The CSAs of the gastric antrum in group M were lower than those in group S, and the greatest difference between the two groups occurred at T30 ( p < 0.001). The differences between the two groups in GER and GER/min were also statistically significant ( p < 0.001); those differences in group M were higher than those in group S, and the greatest differences between the two groups occurred at T30 ( p < 0.001). There were no obvious change trends in the properties of the gastric contents and the Perlas grades in either group, and the differences between the two groups were not statistically significant ( p = 0.97). The differences between the two groups in the GV and GV/W at T120 were statistically significant ( p < 0.001), as was the risk of reflux and aspiration at T120 ( p < 0.001). Conclusion: When metoclopramide was used in satiated emergency trauma patients, it accelerated gastric emptying within 30 min and reduced the risk of accidental reflux. However, a normal gastric emptying level was not achieved, which can be attributed to the delaying effect of trauma on gastric emptying., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Lin, He, Cai, Lu, Lin, Lin and Huang.)

Background: Lymph node metastasis can independently predict oral squamous cell carcinoma patients' survival. This study would investigate the genetic and cellular differences between oral squamous cell carcinoma with positive and negative lymph node metastases., Methods: We gathered single-cell RNA sequencing and bulk gene expression data from the Cancer Genome Atlas and Gene Expression Omnibus databases. Sixty lymph node-metastasis-related genes were discovered with refined single-cell RNA sequencing data analysis, and consensus clustering provided three molecular subtypes of oral squamous cell carcinoma. Least absolute shrinkage and selection operator analyses were then utilized to establish a five-gene risk model. CIBERSORT analysis revealed the immune infiltration profile of different risk subgroups., Results: Oral squamous cell carcinoma patients were classified into three subtypes based on the 60 lymph node-metastasis-related key genes identified by single-cell RNA sequencing data. Patients in Subtype 3 showed a tendency for lymph node metastasis and poorer prognosis. Moreover, five biomarkers were selected from the 60 genes to construct a five-gene risk model evaluating the risk of lymph node metastasis. A lower probability of lymph node metastasis and a better prognosis was observed in the low-risk group. The immune infiltration of three different risk groups was explored with CIBERSORT. Besides, further analysis implied different sensitivities of anticancer drugs, including immunotherapy drugs and targeted compounds, in the three risk groups., Conclusion: In view of intratumoral heterogeneity, we found 60 genes associated with lymph node metastasis of oral squamous cell carcinoma. Subsequently, we constructed a five-gene signature that could improve the prediction of lymph node metastasis, clinical outcome, and promote individualized treatment strategies for oral squamous cell carcinoma., (© 2022 John Wiley & Sons A/S.

Solar and radiative warming are smart approaches to maintaining the human body at a metabolically comfortable temperature in both indoor and outdoor scenarios. Nevertheless, existing warming textiles are ineffective in frigid climates because the solar absorption of selective absorbing coating is significantly reduced when coated on rough textile surface. Herein, for the first time, high-entropy nitrides based spectrally selective film (SSF) is introduced on common cotton through a one-step magnetron sputtering method. The well-designed refractive index gradient enables destructive interference effects, offering a roughness-insensitive high solar absorptance (92.8%) and low thermal emittance (39.2%). Impressively, the solar absorptance is 9.1% higher than the reported best-performing selective nanofilm-based textile. As a result, such a textile achieves a record-high photothermal conversion efficiency (82.2% under 0.6 suns, at 0 °C). This textile yields a 3.5 °C drop in the set-point of indoor air-conditioner temperature. Besides, in a winter morning with an air temperature of 7.5 °C, it warms up the human skin by as large as 12 °C under weak sunlight (350 W m -2 ). More importantly, such a superior radiative warming performance is achieved by engineering the widely used cotton without compromising its breathability and durability, showing great potential for practical applications., (© 2022 The Authors.

Harvesting solar energy to enhance thermoelectric generator efficiency is a highly effective strategy. However, it is a grand challenge but essential to increase solar-thermal conversion efficiency. A spectrally selective absorber, which is capable of boosting solar absorptance (α) while suppressing thermal emittance (ε), shows great potential to elevate the solar-thermal conversion efficiency. Herein, we fabricate a multilayer spectrally selective absorber with the assistance of high-entropy nitrides, which shows outstanding spectral selectivity (α/ε = 95.2/10.9%). Benefitting from the high-entropy nitrides, it is experimentally demonstrated that the as-deposited absorber exhibits superior thermal stability, which is crucial to ensure service life. Under 1000 W·m -2 simulated solar illumination, it achieves a very high surface temperature of 109.6 °C, making it suitable to enhance the efficiency of solar thermoelectric generators. Impressively, the integration of the proposed absorber with a commercial thermoelectric generator efficiently reinforces thermoelectric performance, offering a high output power of 1.99 mW. More importantly, by taking advantage of a thermal concentration strategy, it enables a further increase of the output power by 2.98 mW. This work provides a promising solar-thermal material to boost high thermoelectric performance and extends the application category of high-entropy nitrides.

Abscisic acid (ABA) receptors are considered as the targeted manipulation of ABA sensitivity and water productivity in plants. Regulation of their stability or activity will directly affect ABA signalling. Mitogen-activated protein kinase (MAPK) cascades link multiple environmental and plant developmental cues. However, the molecular mechanism of ABA signalling and MAPK cascade interaction remains largely elusive. TaMPK3 overexpression decreases drought tolerance and wheat sensitivity to ABA, significantly weakening ABA's inhibitory effects on growth. Under drought stress, overexpression lines show lower survival rates, shoot fresh weight and proline content, but higher malondialdehyde levels at seedling stage, as well as decreased grain width and 1000 grain weight in both glasshouse and field conditions at the adult stage. TaMPK3-RNAi increases drought tolerance. TaMPK3 interaction with TaPYL4 leads to decreased TaPYL4 levels by promoting its ubiquitin-mediated degradation, whereas ABA treatment diminishes TaMPK3-TaPYL interactions. In addition, the expression of ABA signalling proteins is impaired in TaMPK3-overexpressing wheat plants under ABA treatment. The MPK3-PYL interaction module was found to be conserved across monocots and dicots. Our results suggest that the MPK3-PYL module could serve as a negative regulatory mechanism for balancing appropriate drought stress response with normal plant growth signalling in wheat., (© 2022 The Authors.

This study aims to explore the factors influencing the success rate of the microdissection testicular sperm extraction (Micro-TESE) in patients with nonobstructive azoospermia (NOA) and cryptorchidism. Clinical data of 162 patients with cryptorchidism who underwent Micro-TESE due to infertility from December 2015 to May 2020 in the First Affiliated Hospital of Nanjing Medical University were analyzed retrospectively. In the univariate analysis, significant differences in the age of patient at the time of orchidopexy (median [interquartile range, IQR]: 7.0 [4.0-11.0] years vs 11.5 [9.0-14.5] years, P < 0.001), interval between orchidopexy and Micro-TESE (mean ± standard deviation: 17.5 ± 5.0 years vs 14.4 ± 4.4 years, P < 0.001), severity of cryptorchidism (unilateral [62.8%] vs bilateral [31.6%], P < 0.001; location of cryptorchidism, intra-abdominal [27.3%] vs inguinal [44.8%] vs suprascrotal [66.7%], P < 0.001), volume of the dominant testis (median [IQR]: 17.00 [15.00-19.00] ml vs 14.50 [11.75-16.25] ml, P < 0.001), and levels of follicle-stimulating hormone (FSH; P = 0.004) and testosterone (P = 0.006) were observed between the successful and failed sperm extraction groups. After conducting the multivariate analysis, four of these factors, including unilateral/bilateral cryptorchidism (P < 0.001), location of cryptorchidism (P = 0.032), age of orchidopexy (P < 0.001), and dominant testicular volume, were adopted in the clinical prediction model to evaluate preoperatively the success rate of Micro-TESE for patients with NOA and cryptorchidism. The likelihood of successful sperm retrieval by Micro-TESE in men with NOA and cryptorchidism increased in patients with mild forms of cryptorchidism., Competing Interests: None

Background: Limited studies have focused on the associated clinicopathologic features and short-term prognostic impacts of metastatic patterns at initial diagnosis in differentiated thyroid cancer (DTC)., Methods: Overall, 530 individuals with distant DTC diagnosed between 2010 and 2014 were identified from Surveillance, Epidemiology, and End Results (SEER) database. Multinomial logistic regression model was used to assess the clinicopathologic factors influencing the pattern of distant metastasis. Kaplan-Meier method and multivariable Cox regression were used to estimate the short-term effects of metastatic patterns on overall (OS) and thyroid cancer-specific survival (TCSS)., Results: Fifty, 111, 263, 59 and 47 patients presented with distant lymph node (LN)-only, bone-only, lung-only, bone plus lung, and liver and/or brain metastases (Mets), respectively. Regional lymph node metastasis (LNM) and follicular histotype were the only confirmed risk factors for distant LN-only Mets and bone-only Mets, respectively. Larger tumour size, extrathyroidal extension (ETE) and papillary histotype were associated with lung-only Mets. Synchronous bone and lung Mets were more likely to occur in older patients. In addition, patients with distant LN-only Mets had hardly any negative effect on OS and TCSS, whereas those with synchronous bone and lung or liver/brain Mets predicted unfavourable short-term outcomes, regardless of whether they received total thyroidectomy and radioisotopes., Conclusions: Different clinicopathologic factors predispose to different patterns of metastases with profound short-term survival differences among DTC patients. Our findings may help to determine effective pretreatment screening for aggressive metastatic patterns at initial diagnosis, and thus to provide additional treatment or access of clinical trials for these patients., (© 2021 John Wiley & Sons Ltd.)

The objective of this study is to demonstrate a novel method for the reconstruction of right recurrent laryngeal nerve (RLN) by transforming into nonrecurrent RLN: the end-to-free vagal laryngeal branch end anastomosis. Here we report a case of locally advanced thyroid carcinoma. The patient underwent radical thyroid surgery with inevitably partial RLN resection and immediate right RLN reconstruction at our institution. With the guidance of intraoperative neuromonitoring (IOMN), we completed a novel end-to-free vagal laryngeal branch end anastomosis. The whole procedure was deliberately monitored by IOMN. Surgeons can procure adequate free nerve for tension-free anastomosis by transforming the right RLN into nonrecurrent nerve. Follow-up laryngoscope showed improved adductory movement of the right arytenoid. The end-to-free vagal end anastomosis is an effective way to reconstruct segmental nerve resection of right RLN. Its long-term postoperative result needs to be further warranted., (© 2021 Wiley Periodicals LLC.)

Background: This study aims to compare the success rate of thoracic paravertebral block (TPVB) and the effect of postoperative analgesia between two approaches., Methods: A total of 34 patients with American Society of Anesthesiology (ASA) physical status score II-III, undergoing an optional thoracoscopic surgery, were randomly assigned to a parasagittal approach group (group P, n = 17) and a transverse intercostal approach group (group T, n = 17). The catheterization time, success rate of the puncture and catheterization, block plane and effect at the surgical site were compared between two groups. The mean arterial pressure and heart rate were recorded, as well as the cold tactile block plane and numeric rating scale (NRS) at 0.5, 2, 4, 8, 12, 24, and 48 h after surgery. The study was registered at http://www.chictr.org.cn/showproj.aspx?proj=9624 (Registration number: ChiCTR2100054642)., Results: The catheterization time in group P was significantly longer than that in group T ( P < 0.05). The success rate of catheterization in group P was lower than that in group T, but no statistical significance ( P = 0.085). There was no significant difference in the success rate of Puncture and blocking effect of the surgical site at 30 min post-injection between two groups ( P > 0.05). There was no significant difference in the cold tactile block plane and NRS scores during coughing between two groups at 0.5, 2, 4, 8, 12, 24, and 48 h postoperatively ( P > 0.05)., Conclusion: This study suggests that there is no significant difference in postoperative block level or pain score during coughing for thoracoscopic surgery between ultrasound-guided parasagittal and transverse intercostal approach, but the parasagittal approach takes longer and has a higher failure rate., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Huang, Lu, Li, Zhang, Jiang and Lin.)

Background: Ultrasound-guided needle placement has revolutionized the thoracic paravertebral block technique and can be applied in thoracoscopic surgery., Objective: This study investigated the median effective volume (EV50) of an ultrasound-guided single shot of 0.3% ropivacaine used as a thoracic paravertebral nerve block for the radical thoracoscopic resection of lung cancer., Methods: A total of 27 patients who received a single shot of ultrasound-guided thoracic paravertebral nerve block and underwent radical thoracoscopic resection of lung cancer were enrolled in this study between February 10 and August 13, 2018. All patients were rated as ASA grades I or II. Using ultrasound as a guide, the block needle was gradually pushed through the lateral costotransverse ligaments to the thoracic paravertebral space by the in-plane technique. After confirming the absence of blood or cerebrospinal fluid, 1-2 ml of 0.3% ropivacaine hydrochloride was injected to confirm that the position of the needle was appropriate, and a pre-determined volume of 0.3% ropivacaine hydrochloride was then administered to the patients. Sensory testing by pinprick was performed every 5 minutes for 30 minutes following the thoracic paravertebral block injection to identify the time segments during which the loss of sensation to the pinprick and its blocking effect occurred., Results: All patients completed the study and 14 (51.8%) had a successful block., Conclusion: The EV50 of 0.3% ropivacaine was 18.46 ml (95% CI 17.09-19.95 ml) and the EV95 was 20.89 ml.

Drought and salt stresses impose major constraints on soybean production worldwide. However, improving agronomically valuable soybean traits under drought conditions can be challenging due to trait complexity and multiple factors that influence yield. Here, we identified a nuclear factor Y C subunit (NF-YC) family transcription factor member, GmNF-YC14, which formed a heterotrimer with GmNF-YA16 and GmNF-YB2 to activate the GmPYR1-mediated abscisic acid (ABA) signalling pathway to regulate stress tolerance in soybean. Notably, we found that CRISPR/Cas9-generated GmNF-YC14 knockout mutants were more sensitive to drought than wild-type soybean plants. Furthermore, field trials showed that overexpression of GmNF-YC14 or GmPYR1 could increase yield per plant, grain plumpness, and stem base circumference, thus indicating improved adaptation of soybean plants to drought conditions. Taken together, our findings expand the known functional scope of the NF-Y transcription factor functions and raise important questions about the integration of ABA signalling pathways in plants. Moreover, GmNF-YC14 and GmPYR1 have potential for application in the improvement of drought tolerance in soybean plants., (© 2021 The Authors.

Background: Surgery is the primary treatment for locally advanced thyroid cancer. For some cases, R0/R1 resection could not be achieved at initial diagnosis and neoadjuvant treatment would be an option. Anlotinib is a multitarget tyrosine kinase inhibitor, which demonstrated antitumor activity in radioiodine-refractory differentiated thyroid cancer and medullary thyroid cancer. We aimed to evaluate the efficacy and safety of anlotinib in locally advanced thyroid cancer in the neoadjuvant setting. Methods: This single-arm phase II study investigated the efficacy and safety of anlotinib (12 mg orally daily, 2 weeks on/1 week off) for 2-6 cycles in patients with locally advanced thyroid cancer in the neoadjuvant setting. The key eligibility criteria included age 14-80 years old; locally advanced thyroid cancer that would benefit from surgery, and at least one measurable lesion. Operable patients received surgery after neoadjuvant treatment. The primary endpoint was objective response rate (ORR). Results: A total of 13 patients were enrolled and received an average of 3.5 cycles of anlotinib treatment. The ORR of anlotinib was 76.9% (95% confidence interval: 46.2-95.0%). The R0/R1 resection rate in the intent-to-treat population was 61.5% and in the per-protocol population was 72.7%. The median time to response was 61.5 days, and the disease control rate at 18 weeks was 92.3%. No patients had blood transfusion or tracheotomy. Most adverse events (AEs) were grade 1 or 2 and tended to discontinue when neoadjuvant treatment ceased. Common AEs of all grades were hypertension (76.9%), hypertriglyceridemia (69.2%), proteinuria (53.8%), thyrotropin increase (53.8%), cholesterol elevation (53.8%), and hand-foot syndrome (38.5%). Conclusions: Anlotinib demonstrated antitumor activity in the neoadjuvant treatment and the majority of patients achieved R0/R1 resection. AEs were consistent with the known anlotinib AE profile. These results suggest that anlotinib neoadjuvant treatment represents a new option for locally advanced thyroid cancer. Clinical Trial Registration Number: NCT04309136.

As an inherent feature of vector optical field, the spatial distribution of polarization brings additional degrees of freedom to engineer the optical field and control the interaction between light and matters. Here we focus on the variation of polarization in single vector optical field, which can be defined by the trajectory on the Poincaré sphere. Based on the amplitude-phase-polarization joint modulation method we propose, vector optical field, whose variation of polarization follows arbitrary circular trajectory on the Poincaré sphere, can be generated. Moreover, the tightly focusing behaviors of the vector optical fields with the polarization varying along parallel circles on the Poincaré sphere are compared. Relations between the circular trajectory and the central intensity of the hollow focal field are concluded.

Context: The role of immune-related genes (IRGs) in thyroid cancer dedifferentiation and accompanying immune exhaustion remains largely unexplored., Objective: To construct a significant IRG-based signature indicative of dedifferentiation and immune exhaustion in thyroid cancer., Design and Settings: One exploratory cohort and 2 validation cohorts were used to identify stably dysregulated IRGs in dedifferentiated thyroid cancer (DDTC) and to obtain independent risk factors for dedifferentiation. The IRGs formed a gene signature, whose predictive value was tested by the receiver operating characteristic curve. Correlations between the signature and differentiation-related genes, immune checkpoints, and prognosis were analyzed. Gene set enrichment analyses were performed to identify related signaling pathways., Results: Four IRGs (PRKCQ, PLAUR, PSMD2, and BMP7) were found to be repeatedly dysregulated in DDTC, and they formed an IRG-based signature with a satisfactory predictive value for thyroid cancer dedifferentiation. Correlation analyses revealed that immune checkpoints were closely related to the 4 IRGs and the IRG-based signature, which was significantly associated with the histological subtype (P = 0.026), lymph node metastasis (P = 0.001), and BRAFV600E mutation (P < 0.001). The downregulated expression of PRKCQ shortened the disease-free survival for patients with thyroid cancer. Furthermore, we identified several signaling pathways inherently associated with the IRG-based signature., Conclusions: This study suggests that IRGs participate in the dedifferentiation and immune exhaustion process of thyroid cancer and are potential biomarkers for DDTC., (© The Author(s) 2021.

Thyroid cancer is the most common type of endocrine malignancy. Although the general prognosis is good, the treatment of advanced disease is still challenging. Exosomes are vesicle units containing specific components that transmit information between cells. In order to explore its role in papillary thyroid cancer (PTC), our study screened exosome enriched lncRNA SNHG9 by lncRNA chip and explored its biological function. We used lncRNA chips combined with bioinformatics analysis to screen lncRNA SNHG9 enriched in exosomes. GO analysis suggested its relationship with autophagy and apoptosis. Quantitative PCR showed SNHG9 was highly expressed in PTC cells and exosomes and its correlation with PTC tumor size was analyzed by clinical characteristics. SNHG9 could inhibit the protective cell autophagy induced by starvation of human normal thyroid epithelial cell line Nthy-ori-3 and promote its apoptosis through PTC cell exosomes. RNA-pull down combined with protein spectrum showed that SNHG9 could interact with YBOX3. Western blot and RNA immunoprecipitation further confirmed their interaction. Western blot showed that SNHG9 could induce degradation of YBOX3, thus interfering with the stability of P21 mRNA and inducing cell apoptosis. In conclusion, our study identified SNHG9 as a PTC cell exosome-enriched lncRNA. SNHG9 could inhibit cell autophagy and promote apoptosis of Nthy-ori-3 cell through YBOX3/P21 pathway., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Wen, Liu, Lu, Cao, Ji and Wei.)

Two-dimensional transition metal dichalcogenide MnSe 2 (2D-MnSe 2 ) with Curie temperature approximate to 300 K has a significant spintronic application on thin-film devices. We demonstrate theoretically a tunable magnetic transition of 2D-MnSe 2 between anti-ferromagnetic (AFM) metal and ferromagnetic (FM) half metal as strain increasing. Mechanism of that transition involves a competition between d - p - d through-bond and d - d direct interaction in 2D-MnSe 2 . Hole doping is an alternative way to enhance the stability of FM coupling. Adsorption (including Li, Na, Cl and F) and vacancy (Mn and Se) studies confirm that the controllable magnetism of 2D-MnSe 2 is related to both interaction competition and charge doping. Tensile strains can greatly amplify through-bond interaction and exchange parameters, resulting in a sharp increase of Curie temperature., (© 2021 IOP Publishing Ltd.)

A new α-emitting isotope ^{214}U, produced by the fusion-evaporation reaction ^{182}W(^{36}Ar,4n)^{214}U, was identified by employing the gas-filled recoil separator SHANS and the recoil-α correlation technique. More precise α-decay properties of even-even nuclei ^{216,218}U were also measured in the reactions of ^{40}Ar, ^{40}Ca beams with ^{180,182,184}W targets. By combining the experimental data, improved α-decay reduced widths δ^{2} for the even-even Po-Pu nuclei in the vicinity of the magic neutron number N=126 are deduced. Their systematic trends are discussed in terms of the N&#95;{p}N&#95;{n} scheme in order to study the influence of proton-neutron interaction on α decay in this region of nuclei. It is strikingly found that the reduced widths of ^{214,216}U are significantly enhanced by a factor of two as compared with the N&#95;{p}N&#95;{n} systematics for the 84≤Z≤90 and N<126 even-even nuclei. The abnormal enhancement is interpreted by the strong monopole interaction between the valence protons and neutrons occupying the π1f&#95;{7/2} and ν1f&#95;{5/2} spin-orbit partner orbits, which is supported by the large-scale shell model calculation.

Introduction: Sialoliths can be removed by sialendoscopy in some cases. But sometimes it fails if the stone is located in the proximal or hilum of Wharton's duct., Aim: To evaluate the clinical efficacy of the sialendoscopy-assisted intraoral incision approach to remove large stones located in the proximal or hilum of Wharton's duct, when sialendoscopy alone fails., Material and Methods: Twenty patients with large stones located in the proximal or hilum of Wharton's duct were included in our study. We used a sialendoscopy-assisted intraoral incision approach to remove large stones located in the proximal or hilum of Wharton's duct when endoscopy failed. The complications and treatment effect were observed., Results: The stones were removed successfully in this way in all patients. Two cases had tongue numbness after the operation, and recovered 3 months later without additional intervention. No swelling or pain appeared during the 3-month to 1-year follow-up. Saliva could be observed from the orifice in 15 patients, with little or none in 5 patients., Conclusions: The sialendoscopy-assisted intraoral incision approach to remove large stones located in the proximal or hilum of Wharton's duct is effective and safe., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2020 Fundacja Videochirurgii.)

Context: Programmed cell death protein-1 (PD-1), cytotoxic T-lymphocyte antigen 4 (CTLA-4), T-cell immunoglobulin and mucin-domain containing-3 (TIM-3), lymphocyte activation gene-3 (LAG-3), and T-cell immunoglobulin and ITIM domain (TIGIT) are considered major immune co-inhibitory receptors (CIRs) and the most promising immunotherapeutic targets in cancer treatment, but they are largely unexplored in medullary thyroid carcinoma (MTC)., Objective: We aimed to provide the first evidence regarding the expression profiles and clinical significance of CIRs in a large cohort of MTC patients., Design and Patients: In total, 200 MTC patients who received initial surgery in our hospital were included. Immunohistochemistry was performed to evaluate CIR expressions in tissue microarrays (TMAs). Combined with the results of our previous programmed cell death ligand-1 (PD-L1) study, clinicopathologic and prognostic correlations of these proteins were retrospectively analyzed., Results: TIM-3, PD-1, CTLA-4, LAG-3, and TIGIT positivity was detected in 96 (48.0%), 27 (13.5%), 25 (12.5%), 6 (3.0%), and 6 (3.0%) patients, respectively, in whom TIM-3, PD-1, and CTLA-4 expressions were positively correlated. Log-rank tests and multivariate Cox analyses both indicated that TIM-3, CTLA-4 expression, and PD-1/PD-L1 coexpression were associated with worse structural recurrence-free survival. In addition, among 20 patients who developed advanced disease during follow-up, 12 (60%) showed TIM-3 positivity, among whom 6 cases also had concurrent moderate to strong PD-1, PD-L1, or CTLA-4 expression., Conclusions: Using the currently largest TMA cohort of this rare cancer, we delineated the CIR expression profiles in MTC, and identified TIM-3, CTLA-4 expression, and PD-1/PD-L1 coexpression as promising biomarkers for tumor recurrence. Furthermore, a subset of advanced MTCs are probably immunogenic, for which single or combined immunotherapy including TIM-3, PD-1, PD-L1, or CTLA-4 blockade may be potential therapeutic approaches in the future., (© The Author(s) 2020.

Ankyrin repeat (ANK) proteins are essential in cell growth, development, and response to hormones and environmental stresses. In the present study, 226 ANK genes were identified and classified into nine subfamilies according to conserved domains in the soybean genome ( Glycine max L.). Among them, the GmANK114 was highly induced by drought, salt, and abscisic acid. The GmANK114 encodes a protein that belongs to the ANK-RF subfamily containing a RING finger (RF) domain in addition to the ankyrin repeats. Heterologous overexpression of GmANK114 in transgenic Arabidopsis improved the germination rate under drought and salt treatments compared to wild-type. Homologous overexpression of GmANK114 improved the survival rate under drought and salt stresses in transgenic soybean hairy roots. In response to drought or salt stress, GmANK114 overexpression in soybean hairy root showed higher proline and lower malondialdehyde contents, and lower H 2 O 2 and O 2- contents compared control plants. Besides, GmANK114 activated transcription of several abiotic stress-related genes, including WRKY13 , NAC11 , DREB2 , MYB84 , and bZIP44 under drought and salt stresses in soybean. These results provide new insights for functional analysis of soybean ANK proteins and will be helpful for further understanding how ANK proteins in plants adapt to abiotic stress., (Copyright © 2020 Zhao, Lu, Sun, Fang, Chen, Zhou, Chen, Ma, Xu and Min.)

Background: Patients with anaplastic thyroid cancer (ATC), which is among the deadliest of all cancers, often have a poor response to traditional therapies. Currently, the role of long non-coding RNAs (lncRNAs) in ATC carcinogenesis is unclear. In this study, we analyzed the lncRNA expression profile of ATC with the aim of identifying potential molecular targets for treatment of the disease., Methods: Whole transcriptome sequencing of three ATC and two normal thyroid (NT) samples was performed, and the lncRNA expression profile of ATC was analyzed. Original data as well as datasets deposited in the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) were used for clinical validation. Cell proliferation, Transwell, and apoptosis assays were performed using ATC cell lines. Gene Ontology (GO) and gene set enrichment analyses (GSEA) were performed to determine the dysregulated pathways., Results: Whole transcriptome sequencing revealed 182 lncRNAs to be differentially expressed in ATC. One of the lncRNAs, mitotically associated long non-coding RNA ( MANCR ; LINC00704), was significantly overexpressed in ATC cell lines and patient samples compared with NT and papillary thyroid cancer (PTC). MANCR depletion in ATC cells significantly inhibited cancer cell proliferation and invasion, and induced apoptosis. By further analyzing the transcriptome data, we identified 451 genes co-expressed with MANCR . GO and GSEA showed that the top dysregulated pathways were related to mitosis and cell cycle., Conclusions: MANCR is a tumor promoter in ATC, and its role in carcinogenesis is possibly associated with cell cycle regulation. Because MANCR expression is minimal in most normal tissues, it may serve as a potential target in the future treatment of ATC., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/atm-20-4530).

The incidence of papillary thyroid cancer (PTC) with concomitant Hashimoto thyroiditis (HT) is increasing. Interleukin (IL)-10 is a cytokine previously reported to be elevated in this condition. Evidence from multiple human malignancies showed IL-10 participated in tumor immunity and exhibited therapeutic potential. The aim of this study is to investigate whether IL-10 interferes with tumor immunity in PTC with concomitant HT. Expression of IL-10 and major histocompatibility complex (MHC) class Ⅰ were compared with PTC tissues with or without concomitant HT. PTC cell lines K1 and TPC-1 were stimulated with IL-10 and analyzed for MHC class Ⅰ expression afterward. T-cell activation, production of IL-2 and interferon (IFN)-γ and programmed death-1 (PD-1) expression were assessed by coculture of donor peripheral blood lymphocytes (PBLs) with IL-10-pretreated PTC cells. Programmed death-ligand 1 (PD-L1) expression was measured in PTC tissues and IL-10-pretreated cells of K1 and TPC-1. Increased levels of IL-10 and MHC class Ⅰ were observed in PTC with concomitant HT. IL-10 stimulation increased MHC class Ⅰ expression of PTC cells in vitro. Coculture of PBLs with IL-10-pretreated PTC cells enhanced T-cell activation (% cluster of differentiation [CD]25+ of CD3+T cells) and increased IL-2 production along with decreased IFN-γ secretion and PD-1 expression. Reduced PD-L1 expression was seen in PTC + HT tissue samples and IL-10-stimulated PTC cell lines. Elevated IL-10 expression in PTC with concomitant HT restores MHC class Ⅰ expression and interferes with tumor immunity. The potential mechanism of IL-10 in tumor immunity needs further investigation., (© Endocrine Society 2020.)

Introduction: This study aimed to compare the challenge of puncture and catheterization and the effect of postoperative analgesia of ultrasound-guided continuous thoracic paravertebral block and the continuous epidural analgesia in patients receiving thoracoscopic surgery for lung cancer., Methods: One-hundred and fifty patients received elective unilateral thoracoscopic surgery for lung cancer and were randomized into three groups; test group 1 (T group), test group 2 (P group), and the control group (E group). Both of the test groups received ultrasound-guided continuous thoracic paravertebral block (TPVB) while the control group received continuous epidural analgesia. After the operation, all the patients in the test groups received the same postoperative analgesia; loading dose 0.5 mg kg -1 , background dose 0.25 mg kg -1  h -1 , patient controlled analgesia (PCA) 0.25 mg kg -1 , and a locking time of 60 min, while the patients in the control group received a loading dose of 5 ml, a background dose of 5 ml h -1 , and a locking time of 20 min. The outcomes of this study were the success rate of the puncture and catheter placement, the blocked segments, numerical rating scale (NRS) scores at rest and during coughing, and the segments with reduced or lost cold and pinpricking sensation., Results: The success rates of the puncture and catheterization in group T were the highest. Compared with group P, the failure rate of the puncture in group E was lower (p < 0.05), but the success rate of catheterization was higher (p < 0.05). The puncture time in group T was the shortest; there was no difference between group E and group T. The time of catheterization in group P was the longest, this was followed by group T, and was the fastest in group E. The stable time of the block level in group E was shorter than that in groups P and T, but was similar between groups P and T. The block level of all three groups in the 4 h postoperative period was similar (p > 0.05), while the 4 h postoperative levels of groups P and T were reduced significantly (p < 0.05)., Conclusion: The continuous analgesia technique of paravertebral space catheterization cannot replace the continuous epidural analgesia in thoracoscopic lung cancer surgery as the latter technique is still considered to be the gold standard., Trial Registration: China Clinical Trial Registration Center identifier ChiCTR1900020973.

The impact of Hashimoto's thyroiditis (HT) on the progression of papillary thyroid cancer (PTC) is still unclear. Interleukin-2 (IL-2) is a growth factor and crucial for HT development. This study aimed at investigating the effect of IL-2 on MHC class I expression in PTC cells and immune activation with experimental treatment for PTC using PTC cell lines. We assessed the expression of IL-2, HLA class I, PD-L1, CD3, CD8 and CD16 molecules in paired PTC tissues and HLA-ABC and PD-L1 expression in IL-2 pre-treated K1, TPC-1 and BCPAP cells by immunohistochemistry, qPCR, flow cytometry and Western blotting. The effect of IL-2 on immunogenicity of PTC cells to stimulate activated human T cells was determined for the percentages of activated CD8+ T cells and their cytokine production as well as PD-1 and PD-L1 expression. Compared with non-tumor tissues, we found that IL-2 expression was up-regulated in PTC tissues, particularly in PTC+HT tissues and correlated positively with HLA-class I, CD3 and CD8 expression in PTC+HT tissues. Conversely, PD-L1 expression decreased in PTC+HT tissues. Treatment with IL-2 significantly up-regulated HLA-class I expression, but down-regulated PD-L1 expression in PTC cells. Co-culture with IL-2-pre-treated PTC cells significantly promoted the proliferation of activated CD8+ T cells and their IL-2 secretion, but decreased their PD-1 expression, accompanied by decreased PD-L1 expression in IL-2-treated PTC cells in vitro. In conclusion, IL-2 up-regulated HLA-class I expression and enhanced anti-tumor T cell immunity during the development of PTC and HT. IL-2 may be a promising immunotherapy for PTC., Competing Interests: Competing Interests: The authors have declared that no competing interest exists., (© The author(s).)

Interest on the nonlinear optical (NLO) switches that turn on/off the second-harmonic generation (SHG) triggered by the external stimulus (such as heat) have continuously grown, especially on the solid-state NLO switches showing superior stability, reversibility, and reproducibility. Herein, we discover (NH 4 ) 2 PO 3 F, as an entirely new solid-state NLO switch showing outstanding switch contrast and reversibility as well as strong SHG intensity (1.1 × KH 2 PO 4 (KDP)) and high laser-induced damage threshold (2.0 × KDP), undergoes a unique first-order phase transition that originates from a reversible hydrogen-bond rearrangement and needs to overcome an energy barrier. Accordingly, we put forward a strategy to continuously modify such an energy barrier by reducing the number of hydrogen bonds per unit cell via an isoelectronic replacement of NH 4 + by K + with a similar size yet incapability of providing any hydrogen bond. Consequently, K x (NH 4 ) 2- x PO 3 F ( x = 0-0.3) exhibiting excellent switching performance are obtained. Remarkably, K x (NH 4 ) 2- x PO 3 F not only realizes a continuously tunable T c spanning from 270 to 150 K, representing the widest NLO switching temperature range ever known but also indicates the first solid-state NLO switch example with continuous T c . Intrinsically, such a T c decline depends on the weakening degree of the hydrogen-bonding interactions in the unit cell. These new insights will shed useful light on the future material design and open new application possibilities.

Endeavors towards identifying key molecular markers for early diagnosis and treatment are driving the clinical study of papillary thyroid carcinoma (PTC). Recent studies have indicated that protein phosphatase, Mg2+/Mn2+ dependent, 1D (PPM1D) exerts an oncogenic function by increasing cell proliferation, migration and invasion in various cancer types. In addition, PPM1D has a high frequency of genetic alterations and has been proposed as a tumor driver in thyroid cancer, making PPM1D an attractive potential oncotarget for cancer treatment. The aims of the present study were to investigate the downstream targets of PPM1D and the potential molecular mechanisms of its oncogenic activities, as well as its clinical significance in PTC. As anticipated, PPM1D overexpression was confirmed in PTC clinical specimens. Furthermore, knockdown of PPM1D in thyroid cancer cell lines significantly suppressed the proliferation, migration and invasion but facilitated cell apoptosis. The protein levels of phosphorylated p38 mitogen‑activated protein kinase (MAPK), p53 and Bax were increased in PPM1D‑knockdown cells, while inhibition of p38 phosphorylation restored cell migration, proliferation and cell apoptosis. In addition, silencing of PPM1D expression induced nuclear translocation of p53 in K‑1 and TPC‑1 cells. The present results demonstrated that PPM1D regulated p38 MAPK and p53 signaling pathways to promote thyroid cancer progression. Collectively with the clinical results, these data qualified PPM1D as a potential diagnostic biomarker and therapeutic target in human thyroid cancer.

Purpose: The role of lymph node ratio (LNR, ratio of metastatic to examined nodes) in the staging of multiple human malignancies has been reported. We aim to evaluate its value in salivary gland cancer (SGC)., Methods: Records of SGC patients from Surveillance, Epidemiology, and End Results database (SEER, training set, N = 4262) and Fudan University Shanghai Cancer Center (FUSCC, validating set, N = 154) were analyzed for the prognostic value of LNR. Kaplan-Meier survival estimates, the Log-rank χ 2 test and Cox proportional hazards model were used for univariate and multivariate analysis. Optimal LNR cutoff points were identified by X-tile., Results: Optimal LNR cutoff points classified patients into four risk groups, R0, R1 (≤ 0.17), R2 (0.17-0.56) and R3 (> 0.56), corresponding to 5-year cause-specific survival in SEER patients of 88.6%, 57.2%, 53.1% and 39.7%, disease-free survival in FUSCC patients of 69.2%, 63.3%, 34.6% and 0%, and disease-specific survival in FUSCC patients of 92.3%, 90.0%, 71.4% and 0%, respectively. Compared with TNM staging, TNM + R staging showed smaller AIC values and higher C-index values in the Cox regression model in both patient sets., Conclusions: LNR classification should be considered as a complementary system to TNM staging and LNR classification based clinical trials deserve further research.

A copper-catalyzed efficient enantioselective construction of chiral quaternary carbon-containing chromanes and 3,4-dihydropyrans is reported. The desymmetric C-O coupling is enabled by a chiral dimethylcyclohexane-1,2-diamine ligand and provides the desired products in good yields with high enantioselectivities. This method presents a broad substrate scope and is applicable to diversely substituted aryl bromides and alkenyl bromides. The application is demonstrated by a gram-scale synthesis and derivatization of the products toward valuable building blocks.

Background: We aimed to explore whether the anatomic extent of lymph node metastases (AE-LNM) could independently predict prognosis of node-positive major salivary gland carcinoma (MaSGC)., Methods: A total of 376 pathologically node-positive MaSGC patients were identified from the Surveillance, Epidemiology and End Results database and constituted the training cohort. Using the X-Tile program, these patients were divided into three groups based on AE-LNM degrees. Discrimination of overall survival (OS) and disease-specific survival (DSS) was evaluated and compared with the 8th American Joint Committee on Cancer (AJCC) pN classification. The results were externally validated by 220 patients in a Chinese multicenter cohort (Validation cohort)., Results: Using the training cohort, AE-LNM was divided into Extent 1 (spread to parotid LNs or level I), Extent 2 (spread to level II-IV) and Extent 3 (spread to level V or bilateral LNs or rare LNs). Regarding both OS and DSS, the AE-LNM model revealed clear separation of survival curves, while the pN classification failed to discriminate the prognosis of pN1 and pN2 patients. When we incorporated both the AE-LNM model and AJCC pN classification into the same multivariate Cox analyses, AE-LNM was still an independent prognostic factor, while the AJCC pN classification lost its significance. These results were externally validated by the validation cohort., Conclusion: AE-LNM is an independent nodal prognosticator for node-positive MaSGC and may have improved discriminative ability over the current AJCC pN classification. Integration of anatomic extent of LNM into the current AJCC N classification could be considered., (Copyright © 2019. Published by Elsevier Ltd.)
