miR-135a is highly expressed in patients with gestational diabetes mellitus, and its target genes are also involved in insulin signaling pathway, so it is one biomarker for gestational diabetes mellitus. Herein we designed a dual-mode DNA biosensor for reliable assay of miR-135a based on the fluorescence and colorimetric signals. Several experiments were carried out to demonstrate the assay feasibility and mechanism for this dual-mode DNA biosensor. With optimum parameters, this proposed dual-mode biosensor has been realized sensitive and quantitative assay of miR-135a. For the fluorescence and colorimetric signals, the working ranges are 0.56-61 and 8.3-74 nM, while limits of detection are 0.18 and 3.7 nM respectively. This dual-mode strategy allows two independent signals for miR-135a assay, so it can verify each other to show more accurate results with good fidelity. Furthermore, there is a good selectivity in the biosensor for target miR-135a over other nucleotide variants, as well as good anti-interference ability in complex samples. This dual-mode DNA biosensor provides a new approach for miR-135a assay and miRNA expression profiling in gestational diabetes mellitus., 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 Elsevier B.V.

Purpose: This retrospective cohort study evaluated the accuracy of analog versus virtual wax-ups in prosthetic-driven planning and guided surgery., Methods: There were 73 patients with a single missing posterior tooth who underwent either an analog or virtual wax-up design following a prosthetic-driven concept. Intraoral scans of the final restoration were performed 1 year after completion of the restoration. The accuracy was assessed by comparing the deviation between the final restoration and the wax-up (analog or virtual) of each patient at the prosthetic level. The maximum deviation in six areas (buccal top, buccal mid, buccal bottom, lingual top, lingual mid, and lingual bottom) was recorded. The accuracy was also assessed at the implant level by comparing the deviation between the virtual new implant position, which was redesigned based on the final restoration as the new wax-up, and the planned position. The mean deviations in the coronal, apical, angular, and depth measurements were recorded. A two-tailed independent t-test and a one-way analysis of variance were used., Results: Statistically significant differences were observed between the buccal (P = 0.03) and lingual tops (P = 0.03) at the prosthetic level. Significant differences were observed in the angular (P < 0.01) and coronal (P = 0.01) deviations at the implant level. There were smaller deviations between the analog wax-ups and final restorations regardless of the prosthetic or implant level., Conclusions: Analog wax-ups were preferable to virtual wax-ups for preoperative design in computer-guided implant surgery.

The Sichuan golden snub-nosed monkey (Rhinopithecus roxellana) is a rare and endangered species endemic to China that occupies a particularly important position in the evolutionary history of Rhinopithecus species. Oral health is a crucial aspect of overall well-being in both humans and nonhuman primates. We review the current limited literature on the dental characteristics and dental pathologies related to the golden snub-nosed monkey, based on skeleton data and morphological evidence. The results indicated that this species possesses dental characteristics that are remarkably different from that of other primates such as larger-sized molars with blunt cusp crests, tiny incisor teeth, and strong mandibles with well-developed masticatory muscles. From limited research, dental diseases include caries, periodontal diseases, tooth loss, tooth wear, and other diseases, which can be found in most primates, including golden snub-nosed monkeys. In conclusion, these physiological features have gradually adapted to different environments to meet the requirements of their function. Understanding the tooth characteristics and dental health status of R. roxellana can provide valuable insights into their evolutionary history, dietary habits, and overall health, which is of great significance for the conservation of the entire population. An epidemiological survey and safe and effective inspection methods of the dental health of golden snub-nosed monkeys should be conducted to facilitate conservation behaviors that presented in the future. It is also recommended that zoos link diet and dental health to improve animal welfare., (© 2024 Wiley Periodicals LLC.)

Metabolic reprogramming occurs in cardiomyopathy and heart failure contributing to progression of the disease. Activation of cardiac Hippo pathway signaling has been implicated in mediating mitochondrial dysfunction and metabolic reprogramming in cardiomyopathy, albeit influence of Hippo pathway on lipid profile is unclear. Using a dual-omics approach, we determined alterations of cardiac lipids in a mouse model of cardiomyopathy due to enhanced Hippo signaling and explored molecular mechanisms. Lipidomic profiling discovered multiple alterations in lipid classes, notably reduction of triacylglycerol, diacylglycerol, phospholipids and ether lipids, and elevation of sphingolipids and lysophosphatidylcholine. Mechanistically, we found downregulated expression of PPARα and PGC-1α at mRNA and protein levels, and downregulated expression of PPARα-target genes, indicating attenuated transcriptional activity of PPARα/PGC-1α. Lipidomics-guided transcriptomic analysis revealed dysregulated expression of gene sets that were responsible for enhanced biosynthesis of ceramides, suppression of TG biosynthesis, storage, hydrolysis and mitochondrial fatty acid oxidation, and reduction of peroxisome-localized biosynthesis of ether lipids. Collectively, Hippo pathway activation with attenuated PPARα/PGC-1α signaling is the underlying mechanism for alterations in cardiac lipids in cardiomyopathy and failing heart., Competing Interests: Declaration of competing interest All authors declare that there is no conflict of interest involved in this work., (Copyright © 2024.

Coronavirus disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused secondary pandemic, which still poses a serious threat to physical health and economic development. Herein, the target-driven functionalized DNA hydrogel capillary sensor based on cascade signal amplification and carbon coated cobalt manganese modified by prussian blue and platinum nanoparticles (MnCo@C-Pt-PB NPs) has been successfully developed for dual-mode detection of SARS-CoV-2. The cascade signal amplification triggered by target RNA causes the permeability of the DNA hydrogel loaded in the capillary to be destroyed, thereby releasing the embedded MnCo@C-Pt-PB NPs as signal molecules into 3,3',5,5'-tetramethylbenzidine/hydrogen peroxide (TMB/H 2 O 2 ) solution under the driving of capillarity. The colorless TMB is then catalyzed to blue oxidation products (oxTMB) due to peroxidase-like activity of MnCo@C-Pt-PB NPs, and MnCo@C-Pt-PB NPs and oxTMB with photothermal properties synergistically increase the system temperature under near-infrared irradiation, which are recorded by portable devices to achieve dual-mode detection. Signals intensity are proportional to the logarithm of T-RNA concentration in a wide detection range (100 aM-100 pM), with a detection limit of 100 aM. Moreover, the reliability of the developed method in oropharyngeal swabs samples has also been validated. The signal conversion and amplification function of functionalized DNA hydrogel enhances the convenience, sensitivity and versatility of the developed method, which is promising to be applied in environmental safety, molecular diagnostic assays and disease prevention., 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 Elsevier B.V.

Translating high-performance organic solar cell (OSC) materials from spin-coating to scalable processing is imperative for advancing organic photovoltaics. For bridging the gap between laboratory research and industrialization, it is essential to understand the structural formation dynamics within the photoactive layer during printing processes. In this study, two typical printing-compatible solvents in the doctor-blading process are employed to explore the intricate mechanisms governing the thin-film formation in the state-of-the-art photovoltaic system PM6:L8-BO. Our findings highlight the synergistic influence of both the donor polymer PM6 and the solvent with a high boiling point on the structural dynamics of L8-BO within the photoactive layer, significantly influencing its morphological properties. The optimized processing strategy effectively suppresses the excessive aggregation of L8-BO during the slow drying process in doctor-blading, enhancing thin-film crystallization with preferential molecular orientation. These improvements facilitate more efficient charge transport, suppress thin-film defects and charge recombination, and finally enhance the upscaling potential. Consequently, the optimized PM6:L8-BO OSCs demonstrate power conversion efficiencies of 18.42% in small-area devices (0.064 cm 2 ) and 16.02% in modules (11.70 cm 2 ), respectively. Overall, this research provides valuable insights into the interplay among thin-film formation kinetics, structure dynamics, and device performance in scalable processing.

Whether stem-cell-like cancer cells avert ferroptosis to mediate therapy resistance remains unclear. In this study, using a soft fibrin gel culture system, we found that tumor-repopulating cells (TRCs) with stem-cell-like cancer cell characteristics resist chemotherapy and radiotherapy by decreasing ferroptosis sensitivity. Mechanistically, through quantitative mass spectrometry and lipidomic analysis, we determined that mitochondria metabolic kinase PCK2 phosphorylates and activates ACSL4 to drive ferroptosis-associated phospholipid remodeling. TRCs downregulate the PCK2 expression to confer themselves on a structural ferroptosis-resistant state. Notably, in addition to confirming the role of PCK2-pACSL4(T679) in multiple preclinical models, we discovered that higher PCK2 and pACSL4(T679) levels are correlated with better response to chemotherapy and radiotherapy as well as lower distant metastasis in nasopharyngeal carcinoma cohorts., (© 2024.

Correlation between echocardiographic and pathoanatomic variables and their prognostic value in murine cardiomyopathy models remain unknown. Using echocardiography, morphometrics, and survival monitoring, we characterized transgenic (TG) mice with dilated cardiomyopathy due to cardiac overexpression of β 2 -adrenoceptors focusing on predicting heart failure (HF) risk and HF mortality. In 12-month-old non-TG and TG mice, echocardiography was performed to determine left ventricular (LV) dimensions (d), wall thickness (h), and fractional shortening (FS). Animals were monitored for 3 months for survival. Organ weights and pathological events indicating left HF were determined. TG mice (n = 76) had reduced FS and enlarged LV, and 79% died of HF or likely arrhythmias during the follow-up period while all non-TG mice (n = 26) survived. These mice with left HF also had pulmonary congestion and hypertrophy/dilatation of the right ventricle (RV). Weights of lungs, RV, and atria were intercorrelated (r = 0.79-0.83) and also negatively correlated with FS × (h/d) index (r = -0.502 to -0.609). By FS × (h/d) tertiles, TG mice of low tertiles were identified with the highest mortality (96%) largely due to HF (76%). In conclusion, in aged cardiomyopathy mice a good correlation existed between echocardiographic and pathoanatomic variables. Echocardiography-derived LV function and remodeling were useful in identifying a subgroup of TG mice with a high risk of HF and HF fatality., (© 2024 The Author(s).

Thermophilic anaerobic digestion (AD) of animal manure offers various environmental benefits but the process requires a microbial community acclimatized to high ammonia. In current study, a lab-scale continuous stirred tank reactor (CSTR) fed with chicken manure was operated under thermophilic condition for 450 days in total. Results showed that the volumetric methane production decreased from 445 to 328 and sharply declined to 153 mL L -1 ·d -1 with feeding total solid (TS) step increased from 5% to 7.5% and 10%, respectively. While, after a long-term stop feeding for 80 days, highly disturbed reactor was able to recover methane generation to 739 mL L -1 ·d -1 at feeding TS of 10%. Isotope analysis indicted acetate converted to methane through the syntrophic acetate oxidation and hydrogenotrophic methanogenesis (SAO-HM) pathway increased from 33% to 63% as the concentration of ammonium increased from 2493 to 6258 mg L -1 . Significant different in the genome expression of the SAO bacterial from 0.09% to 1.23%, combining with main hydrogenotrophic partners (Methanoculleus spp. and Methanothermobacter spp.) contented of 2.1% and 99.9% during inhibitory and recovery stages, respectively. The highly expressed KEGG pathway in level 3 (enzyme genes) for the Recovery sludge combining with the extraordinary high abundance of genera Halocella sp. suggested that Halocella sp. might be a highly efficient hydrolytic and acidogenic microorganism and enhance the process of SAO during carbon metabolic flow to methane. This report will be a basis for further study of AD studies on high nitrogen content of poultry manure., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dongmin Yin reports financial support was provided by Changzhou Science and Technology Bureau.

Activation of the sympatho-β-adrenergic receptor (βAR) system is the hallmark of heart disease with adverse consequences that facilitate the onset and progression of heart failure (HF). Use of β-blocking drugs has become the front-line therapy for HF. Last decade has witnessed progress in research demonstrating a pivotal role of Hippo pathway in cardiomyopathy and HF. Clinical studies have revealed myocardial Hippo pathway activation/YAP-TEAD1 inactivation in several types of human cardiomyopathy. Experimental activation of cardiac Hippo signaling or inhibition of YAP-TEAD1 have been shown to leads dilated cardiomyopathy with severe mitochondrial dysfunction and metabolic reprogramming. Studies have also convincingly shown that stimulation of βAR activates cardiac Hippo pathway with inactivation of the down-stream effector molecules YAP/TAZ. There is strong evidence for the adverse consequences of the βAR-Hippo signaling leading to HF. In addition to promoting cardiomyocyte death and fibrosis, recent progress is the demonstration of mitochondrial dysfunction and metabolic reprogramming mediated by βAR-Hippo pathway signaling. Activation of cardiac βAR-Hippo signaling is potent in downregulating a range of mitochondrial and metabolic genes, whereas expression of pro-inflammatory and pro-fibrotic factors are upregulated. Coupling of βAR-Hippo pathway signaling is mediated by several kinases, mechanotransduction and/or Ca 2+ signaling, and can be blocked by β-antagonists. Demonstration of the converge of βAR signaling and Hippo pathway bears implications for a better understanding on the role of enhanced sympathetic nervous activity, efficacy of β-antagonists, and metabolic therapy targeting this pathway in HF. In this review we summarize the progress and discuss future research directions in this field., 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 Elsevier B.V. and Mitochondria Research Society.

Background: Vasovagal syncope (VVS) is the most common type of orthostatic intolerance in children. We investigated whether platelet-related factors related to treatment efficacy in children suffering from VVS treated with metoprolol., Methods: Metoprolol-treated VVS patients were recruited. The median duration of therapy was three months. Patients were followed and divided into two groups, treament-effective group and treatment-ineffective group. Logistic and least absolute shrinkage selection operator regressions were used to examine treatment outcome variables. Receiver-operating characteristic (ROC) curves, precision-recall (PR) curves, calibration plots, and decision curve analyses were used to evaluate the nomogram model., Results: Among the 72 patients who complete the follow-up, treatment-effective group and treatment-ineffective group included 42 (58.3%) and 30 (41.7%) cases, respectively. The patients in the treatment-effective group exhibited higher mean platelet volume (MPV) [(11.0 ± 1.0) fl vs. (9.8 ± 1.0) fl, P < 0.01] and platelet distribution width [12.7% (12.3%, 14.3%) vs. 11.3% (10.2%, 12.2%), P < 0.01] than those in the treatment-ineffective group. The sex ratio was significantly different (P = 0.046). A fit model comprising age [odds ratio (OR) = 0.766, 95% confidence interval (CI) = 0.594-0.987] and MPV (OR = 5.613, 95% CI = 2.297-13.711) might predict therapeutic efficacy. The area under the curve of the ROC and PR curves was computed to be 0.85 and 0.9, respectively. The P value of the Hosmer-Lemeshow test was 0.27. The decision curve analysis confirmed that managing children with VVS based on the predictive model led to a net advantage ranging from 0.01 to 0.58. The nomogram is convenient for clinical applications., Conclusion: A novel nomogram based on age and MPV can predict the therapeutic benefits of metoprolol in children with VVS., (© 2024.

The development of in situ tumor vaccines offers promising prospects for cancer treatment. Nonetheless, the generation of plenary autologous antigens in vivo and their codelivery to DC cells along with adjuvants remains a significant challenge. Herein, we developed an in situ tumor vaccine using a supramolecular nanoparticle/hydrogel composite (ANP MTO /ALCD) and a deformable nanoadjuvant (PPE R848 ). The ANP MTO /ALCD composite consisted of β-cyclodextrin-decorated alginate (Alg- g -CD) and MTO-encapsulated adamantane-decorated nanoparticles (ANP MTO ) through supramolecular interaction, facilitating the long-term and sustained production of plenary autologous antigens, particularly under a 660 nm laser. Simultaneously, the produced autologous antigens were effectively captured by nanoadjuvant PPE R848 and subsequently transported to lymph nodes and DC cells, benefiting from its optimized size and deformability. This in situ tumor vaccine can trigger a robust antitumor immune response and demonstrate significant therapeutic efficacy in inhibiting tumor growth, suppressing tumor metastasis, and preventing postoperative recurrence, offering a straightforward approach to programming in situ tumor vaccines.

Strong near-field enhancements (NFEs) of nanophotonic structures are believed to be closely related to high Purcell factors (F P ). Here, we theoretically show that the correlation is partially correct; the extinction cross section (σ) response is also critical in determining F P . The divergence between NFE and F P is especially pronounced in plasmonic-dielectric hybrid systems, where the plasmonic antenna supports dipolar plasmon modes and the dielectric cavity hosts Mie-like resonances. The cavity's enhanced-field environment can boost the antenna's NFEs, but the F P is not increased concurrently due to the larger effective σ that is intrinsic to the F P calculations. Interestingly, the peak F P for the coupled system can be predicted by using the NFE and σ responses. Furthermore, the limits for F P of coupled systems are considered; they are determined by the sum of the F P of a redshifted (or modified, if applicable) antenna and an individual cavity. This contrasts starkly with the behavior of NFE which is closely associated with the multiplicative effects of the NFEs provided by the antenna and the dielectric cavity. The differing behaviors of NFE and F P in hybrid cavities have varied impacts on relevant nanophotonic applications such as fluorescence, Raman scattering and enhanced light-matter interactions.

Liver fibrosis is a key pathological stage in the progression of chronic liver disease. If the disease is mistreated, it can further deteriorate into liver failure, which seriously affects the quality of life of patients and brings heavy medical costs. Hepatic stellate cell(HSC) activation triggers extracellular matrix(ECM) deposition, which plays an important driving role in liver fibrosis, and ferroptosis is an effective strategy to clear or reverse the activation of HSCs into a deactivated phenotype. Therefore, inhibiting the activation and proliferation of HSCs by regulating ferroptosis is the key to the treatment of this disease, so as to derive the prospect of inducing ferroptosis of HSCs(including RNA-binding proteins, non-coding RNA, chemicals, and active components of traditional Chinese medicine) to intervene in liver fibrosis. On this basis, this paper started from the activation of HSCs to induce ECM deposition and focused on summarizing the mechanism of inducing HSC ferroptosis in delaying the progression of liver fibrosis, so as to continuously enrich the clinical practice of liver fibrosis and provide a reference for subsequent basic research.

Background: Non-anatomical factors significantly affect treatment guidance and prognostic prediction in nasopharyngeal carcinoma (NPC) patients. Here, we developed a novel survival model by combining conventional TNM staging and serological indicators., Methods: We retrospectively enrolled 10,914 eligible patients with nonmetastatic NPC over 2009-2017 and randomly divided them into training (n = 7672) and validation (n = 3242) cohorts. The new staging system was constructed based on T category, N category, and pretreatment serological markers by using recursive partitioning analysis (RPA)., Results: In multivariate Cox analysis, pretreatment cell-free Epstein-Barr virus (cfEBV) DNA levels of >2000 copies/mL [HR OS (95 % CI) = 1.78 (1.57-2.02)], elevated lactate dehydrogenase (LDH) levels [HR OS (95 % CI) = 1.64 (1.41-1.92)], and C-reactive protein-to-albumin ratio (CAR) of >0.04 [HR OS (95 % CI) = 1.20 (1.07-1.34)] were associated with negative prognosis (all P < 0.05). Through RPA, we stratified patients into four risk groups: RPA I (n = 3209), RPA II (n = 2063), RPA III (n = 1263), and RPA IV (n = 1137), with 5-year overall survival (OS) rates of 93.2 %, 86.0 %, 80.6 %, and 71.9 % (all P < 0.001), respectively. Compared with the TNM staging system (eighth edition), RPA risk grouping demonstrated higher prognostic prediction efficacy in the training [area under the curve (AUC) = 0.661 vs. 0.631, P < 0.001] and validation (AUC = 0.687 vs. 0.654, P = 0.001) cohorts. Furthermore, our model could distinguish sensitive patients suitable for induction chemotherapy well., Conclusion: Our novel RPA staging model outperformed the current TNM staging system in prognostic prediction and clinical decision-making. We recommend incorporating cfEBV DNA, LDH, and CAR into the TNM staging system., 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 Elsevier Ltd.

The AJCC/UICC TNM classification describes anatomic extent of tumor progression and guides treatment decisions. Our comprehensive analysis of 8,834 newly diagnosed patients with non-metastatic Epstein-Barr virus related nasopharyngeal carcinoma (NPC) from six Chinese centers indicates certain limitations in the current staging system. The 8th edition of the AJCC/UICC TNM classification inadequately differentiates patient outcomes, particularly between T2 and T3 categories and within the N classification. We propose reclassifying cases of T3 NPC with early skull-base invasion as T2, and elevating N1-N2 cases with grade 3 image-identified extranodal extension (ENE) to N3. Additionally, we suggest combining T2N0 with T1N0 into a single stage IA. For de novo metastatic (M1) NPC, we propose subdivisions of M1a, defined by 1-3 metastatic lesions without liver involvement, and M1b, characterized by >3 metastatic lesions or liver involvement. This proposal better reflects responses of NPC patients to the up-to-date treatments and their evolving risk profiles., Competing Interests: Declaration of interests The authors declare no competing interests., (Copyright © 2023 The Author(s).

Foodborne illness caused by Staphylococcus aureus (S. aureus) has posed a significant threat to human health. Herein, an integrated multifunctional nanoplatform was developed for fluorescence detection and inactivation of S. aureus based on cascade signal amplification coupled with single strand DNA-template copper nanoparticles (ssDNA-Cu NPs). Benefiting from reasonable design, one-step cascade signal amplification was achieved through strand displacement amplification combined with rolling circle amplification, followed by in-situ generation of copper nanoparticles. S. aureus detection could be performed through naked eye observation and microplate reader measurement of the red fluorescence signal. The multifunctional nanoplatform had satisfactory specificity and sensitivity, achieving 5.2 CFU mL -1 detection limit and successful detection of 7.3 CFU of S. aureus in spiked egg after < 5 h of enrichment. Moreover, ssDNA-Cu NPs could eliminate S. aureus to avoid secondary bacterial contamination without further treatment. Therefore, this multifunctional nanoplatform has potential application in food safety dtection., 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.

Aims: Endothelial dysfunction plays a pivotal role in atherosclerosis, but the detailed mechanism remains incomplete understood. Nogo-B is an endoplasmic reticulum (ER)-localized protein mediating ER-mitochondrial morphology. We previously showed endothelial Nogo-B as a key regulator of endothelial function in the setting of hypertension. Here, we aim to further assess the role of Nogo-B in coronary atherosclerosis in ApoE -/- mice with pressure overload., Methods and Results: We generated double knockout (DKO) mouse models of systemically or endothelium-specifically excising Nogo-A/B gene on an ApoE -/- background. After 7 weeks of transverse aortic constriction (TAC) surgery, compared to ApoE -/- mice DKO mice were resistant to the development of coronary atherosclerotic lesions and plaque rapture. Sustained elevation of Nogo-B and adhesion molecules (VCAM-1/ICAM-1), early markers of atherosclerosis, was identified in heart tissues and endothelial cells (ECs) isolated from TAC ApoE -/- mice, changes that were significantly repressed by Nogo-B deficiency. In cultured human umbilical vein endothelial cells (HUVECs) exposure to inflammatory cytokines (TNF-α, IL-1β), Nogo-B was upregulated and activated reactive oxide species (ROS)-p38-p65 signaling axis. Mitofusin 2 (Mfn2) is a key protein tethering ER to mitochondria in ECs, and we showed that Nogo-B expression positively correlated with Mfn2 protein level. And Nogo-B deletion in ECs or in ApoE -/- mice reduced Mfn2 protein content and increased ER-mitochondria distance, reduced ER-mitochondrial Ca 2+ transport and mitochondrial ROS generation, and prevented VCAM-1/ICAM-1 upregulation and EC dysfunction, eventually restrained atherosclerotic lesions development., Conclusion: Our study revealed that Nogo-B is a critical modulator in promoting endothelial dysfunction and consequent pathogenesis of coronary atherosclerosis in pressure overloaded hearts of ApoE -/- mice. Nogo-B may hold the promise to be a common therapeutic target in the setting of hypertension., Competing Interests: Declaration of competing interest The authors declare that there are no confilct of interests., (Copyright © 2023 The Authors.

Here, we theoretically demonstrate a strategy for efficiently turning whispering-gallery-mode (WGM) responses of a subwavelength dielectric disk through their near-field couplings with common low-order electromagnetic resonances of a dielectric block. Both simulations and an analytical coupled oscillator model show that the couplings are Fano interferences between dark high-quality WGMs and bright modes of the block. The responses of a WGM in the coupled system are highly dependent on the strengths and the relative phases of the block modes, the coupling strength, and the decay rate of the WGM. The WGM responses of coupled systems can exceed that of the individual disk. In addition, such a configuration will also facilitate the excitation of WGMs by a normal incident plane wave in experiments. These results could enable new applications for enhancing light-matter interactions.

Purpose: Upper-neck irradiation (UNI) at the uninvolved neck has shown similar regional relapse-free survival as standard whole-neck irradiation (WNI) in patients with N0-1 nasopharyngeal carcinoma. However, whether UNI at the contralateral uninvolved neck is feasible in unilateral N3 disease, defined as >6 cm and/or below the caudal border of the cricoid cartilage, remains unclear., Methods and Materials: Data for 291 patients with nasopharyngeal carcinoma with unilateral N3 disease who were treated with intensity modulated radiation therapy from 2009 to 2015 were retrospectively analyzed. Among them, 190 received bilateral WNI (WNI group); the remaining 101 received WNI at the involved neck and UNI at the contralateral uninvolved neck (UNI group). Survival rates were estimated using the Kaplan-Meier method, and differences between groups were compared using the log rank tests., Results: The median follow-up was 79.4 months (interquartile range, 56.0-89.3). Twenty-five patients had regional lymph node relapses (UNI: 10.9%, 11/101 vs WNI: 7.4%, 14/190; P = .31). Of these, 23 patients relapsed within the previously involved neck regions, while only 2 patients had relapses in the contralateral uninvolved neck (1 each in the UNI and WNI groups). Five-year regional relapse-free survival rates were similar between groups (89.7% vs 92.7%, P = .29). Similar between-group findings were also observed for 5-year overall survival (76.1% vs 80.4%, P = .40), distant metastasis-free survival (74.9% vs 79.2%, P = .44), and local relapse-free survival (95.6% vs 94.7%, P = .64). Furthermore, oncologic outcomes in subgroup and multivariable analyses were similar between groups., Conclusions: Regional control and survival outcomes were comparable in UNI at the contralateral uninvolved neck and standard WNI in patients with nasopharyngeal carcinoma with unilateral N3 disease. Our findings provide evidence for future radiation therapy guidelines of nasopharyngeal carcinoma., (Copyright © 2022 Elsevier Inc. All rights reserved.)

The surveillance of occupational disease has entered a new stage ofdevelopment, with the implementation of the national health informatization project. To improve the efficiency and quality of occupational disease monitoring information reporting in this paper, the system architecture and related management regulations, as long as the major changes and achievement of "surveillance system of occupational disease and health hazards information" under the framework of National Health Insurance Informatization Project were elaborated. The deficiencies existing in the system were analyzed, and expectation for the construction of the occupational disease surveillance system was addressed.

Background: S1P (sphingosine-1-phosphate) has been reported to possess vasodilatory properties, but the underlying pathways are largely unknown., Methods: Isolated mouse mesenteric artery and endothelial cell models were used to determine S1P-induced vasodilation, intracellular calcium, membrane potentials, and calcium-activated potassium channels (K Ca 2.3 and K Ca 3.1 [endothelial small- and intermediate-conductance calcium-activated potassium channels]). Effect of deletion of endothelial S1PR1 (type 1 S1P receptor) on vasodilation and blood pressure was evaluated., Results: Mesenteric arteries subjected to acute S1P stimulation displayed a dose-dependent vasodilation response, which was attenuated by blocking endothelial K Ca 2.3 or K Ca 3.1 channels. In cultured human umbilical vein endothelial cells, S1P stimulated immediate membrane potential hyperpolarization following activation of K Ca 2.3/K Ca 3.1 with elevated cytosolic Ca 2+ . Further, chronic S1P stimulation enhanced expression of K Ca 2.3 and K Ca 3.1 in human umbilical vein endothelial cells in dose- and time-dependent manners, which was abolished by disrupting either S1PR1-Ca 2+ signaling or downstream Ca 2+ -activated calcineurin/NFAT (nuclear factor of activated T-cells) signaling. By combination of bioinformatics-based binding site prediction and chromatin immunoprecipitation assay, we revealed in human umbilical vein endothelial cells that chronic activation of S1P/S1PR1 promoted NFATc2 nuclear translocation and binding to promoter regions of K Ca 2.3 and K Ca 3.1 genes thus to upregulate transcription of these channels. Deletion of endothelial S1PR1 reduced expression of K Ca 2.3 and K Ca 3.1 in mesenteric arteries and exacerbated hypertension in mice with angiotensin II infusion., Conclusions: This study provides evidence for the mechanistic role of K Ca 2.3/K Ca 3.1-activated endothelium-dependent hyperpolarization in vasodilation and blood pressure homeostasis in response to S1P. This mechanistic demonstration would facilitate the development of new therapies for cardiovascular diseases associated with hypertension.

Abstract: Mitochondrial dysfunction plays a key role in the development of heart failure, but targeted therapeutic interventions remain elusive. Previous studies have shown coenzyme Q10 (CoQ10) insufficiency in patients with heart disease with undefined mechanism and modest effectiveness of CoQ10 supplement therapy. Using 2 transgenic mouse models of cardiomyopathy owing to cardiac overexpression of Mst1 (Mst1-TG) or β 2 -adrenoceptor (β 2 AR-TG), we studied changes in cardiac CoQ10 content and alterations in CoQ10 biosynthesis genes. We also studied in Mst1-TG mice effects of CoQ10, delivered by oral or injection regimens, on both cardiac CoQ10 content and cardiomyopathy phenotypes. High performance liquid chromatography and RNA sequencing revealed in both models significant reduction in cardiac content of CoQ10 and downregulation of most genes encoding CoQ10 biosynthesis enzymes. Mst1-TG mice with 70% reduction in cardiac CoQ10 were treated with CoQ10 either by oral gavage or i.p. injection for 4-8 weeks. Oral regimens failed in increasing cardiac CoQ10 content, whereas injection regimen effectively restored the cardiac CoQ10 level in a time-dependent manner. However, CoQ10 restoration in Mst1-TG mice did not correct mitochondrial dysfunction measured by energy metabolism, downregulated expression of marker proteins, and oxidative stress nor to preserve cardiac contractile function. In conclusion, mouse models of cardiomyopathy exhibited myocardial CoQ10 deficiency likely due to suppressed endogenous synthesis of CoQ10. In contrast to ineffectiveness of oral administration, CoQ10 administration by injection regimen in cardiomyopathy mice restored cardiac CoQ10 content, which, however, failed in achieving detectable efficacy at molecular and global functional levels., Competing Interests: The authors report no conflict of interest., (Copyright © 2023 The Author(s).

Takotsubo syndrome (TTS) is characterized by short-term contractile dysfunction with its mechanism undefined. We showed that activation of cardiac Hippo pathway mediates mitochondrial dysfunction and that stimulation of β-adrenoceptors (βAR) activates Hippo pathway. Here, we investigated the role of βAR-Hippo signaling in mediating mitochondrial dysfunction in isoproterenol (Iso)-induced TTS-like mouse model. Elderly postmenopausal female mice were administered with Iso (1.25 mg/kg/h for 23 h). Cardiac function was determined by serially echocardiography. At days 1 and 7 post-Iso exposure, mitochondrial ultrastructure and function were examined by electron microscopy and various assays. Alterations in cardiac Hippo pathway and effects of genetic inactivation of Hippo kinase (Mst1) on mitochondrial damage and dysfunction in the acute phase of TTS were investigated. Isoproterenol exposure induced acute increase in biomarkers of cardiac damage and ventricular contractile dysfunction and dilation. At day 1 post-Iso, we observed extensive abnormalities in mitochondrial ultrastructure, downregulation of mitochondrial marker proteins, and mitochondrial dysfunction evidenced by lower ATP content, increased lipid droplets, higher contents of lactate, and augmented reactive oxygen species (ROS). All changes were reversed by day 7 . βAR stimulation led to activation of cardiac Hippo pathway with enhanced expression of Hippo kinase Mst1 and inhibitory YAP phosphorylation, as well as reduced nuclear YAP-TEAD1 interaction. In mice with cardiac expression of inactive mutant Mst1 gene, acute mitochondrial damage and dysfunction were mitigated. Stimulation of cardiac βAR activates Hippo pathway that mediates mitochondrial dysfunction with energy insufficiency and enhanced ROS, promoting acute but short-term ventricular dysfunction. NEW & NOTEWORTHY Takotsubo syndrome (TTS) is featured by activation of sympatho-β-adrenoceptor (βAR) system leading to acute loss of ventricular contractile performance. However, the molecular mechanism remains undefined. We demonstrated, in an isoproterenol-induced murine TTS-like model, extensive mitochondrial damage, metabolic dysfunction, and downregulated mitochondrial marker proteins, changes temporarily associated with cardiac dysfunction. Mechanistically, stimulation of βAR activated Hippo signaling pathway and genetic inactivation of Mst1 kinase ameliorated mitochondrial damage and metabolic dysfunction at the acute phase of TTS.

Type 2 diabetes mellitus (T2DM) is characterized by chronic low-grade systemic inflammation. Tissue infiltration by monocyte migration contributes to the pathogenesis of vascular complications in T2DM. We studied the role of intermediate-conductance Ca 2+ -activated K + (K Ca 3.1) channels in the palmitic acid (PA)-induced migration of peripheral blood mononuclear cells (PBMCs) from T2DM patients and the influence of advanced glycation endproducts (AGEs). A total of 49 T2DM patients and 33 healthy subjects was recruited into this study. Using flow cytometry and Western blotting analysis as well as cell migration assay, we found that there was a significant decrease in frequency of T lymphocytes and monocytes in CD45 + leukocyte population. PA at 100 μM stimulated migration of PBMCs from T2DM individuals, which was inhibited by the specific K Ca 3.1 channel blocker TRAM-34 (1 μM). The PBMC migration was positively correlated with glycosylated hemoglobin A1 chain (HbA1c) level of T2DM patients, an indicator of AGEs, and PBMCs with higher level of HbA1c showed upregulated expression of toll-like receptor (TLR) 2/4 and K Ca 3.1 channels. In THP-1 cells, AGEs at 200 μg/ml increased protein expression of TLR 2/4 and K Ca 3.1 channels, and were synergistically involved in PA-induced migration through receptors of AGEs (RAGE)-mediated K Ca 3.1 upregulation. In conclusion, in PBMCs of T2DM patients, AGEs promotes PA-induced migration via upregulation of TLR2/4 and K Ca 3.1 channels., Competing Interests: 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., (©2023PublishedbyElsevierLtd.)

Background: This study aimed to identify prognostic signatures to predict the prognosis of breast cancer (BRCA) patients based on a series of comprehensive analyses of gene expression data., Methods: The RNA-sequencing expression data and corresponding BRCA patient clinical data were collected from the Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) datasets. Firstly, the differently expressed genes (DEGs) related to prognosis between tumor tissues and normal tissues were ascertained by performing R package "limma". Secondly, the DEGs were used to construct a polygenic risk scoring model by the weighted gene co-expression network analysis (WGCNA) and the least absolute shrinkage and selection operator Cox regression (Lasso-cox) analysis method. Thirdly, survival analysis was performed to investigate the risk score values in the TCGA cohort. And the enrichment analysis, immune cell infiltration levels analysis, and protein-protein internet (PPI) analysis were performed. Simultaneously, the GEO cohort was used to validate the model. Lastly, we constructed a nomogram to explore the influence of polygenic risk score and other clinical factors on the survival probability of patients with BRCA., Results: A total of 1000 DEGs including 396 upregulated genes and 604 downregulated genes were identified from the TCGA-BRCA dataset. We obtained 5 prognosis-related genes, as the key biomarkers by Lasso-cox analysis ( FBXL19 , HAGHL , PHKG2 , PKMYT1 , and TXNDC17 ), all of which were significantly upregulated in breast tumors. The prognostic prediction of the 5 genes model was great in training and validation cohorts. Moreover, the high-risk group had a poorer prognosis. The Cox regression analysis showed that the comprehensive risk score for 5 genes was an independent prognosis factor., Conclusion: The 5 genes risk model constructed in this study had an independent predictive ability to distinguish patients with a high risk of death from those with a low-risk score, and it can be used as a practical and reliable prognostic tool for BRCA., Competing Interests: The authors declare no conflict of interest., (© 2023 The Authors.

Background: Vascular endothelial dysfunction is regarded as an early event of hypertension. Galectin-3 (Gal-3) is known to participate in various pathological processes. Whilst previous studies showed that inhibition of Gal-3 effectively ameliorates angiotensin II (Ang II)-induced atherosclerosis or hypertension, it remains unclear whether Ang II regulates Gal-3 expression and actions in vascular endothelium., Methods: Using techniques of molecular biology and myograph, we investigated Ang II-mediated changes in Gal-3 expression and activity in thoracic aortas and mesenteric arteries from wild-type and Gal-3 gene deleted (Gal-3 -/- ) mice and cultured endothelial cells., Results: The serum level of Gal-3 was significantly higher in hypertensive patients or in mice with chronic Ang II-infusion. Ang II infusion to wild-type mice enhanced Gal-3 expression in the aortic and mesenteric arteries, elevated systolic blood pressure and impaired endothelium-dependent relaxation of the thoracic aortas and mesenteric arteries, changes that were abolished in Gal-3 -/- mice. In human umbilical vein endothelial cells, Ang II significantly upregulated Gal-3 expression by promoting nuclear localization of Yes-associated protein (YAP) and its interaction with transcription factor Tead1 with enhanced YAP/Tead1 binding to Gal-3 gene promoter region. Furthermore, Gal-3 deletion augmented the bioavailability of nitric oxide, suppressed oxidative stress, and alleviated inflammation in the thoracic aorta of Ang II-infused mice or endothelial cells exposed to Ang II., Conclusions: Our results demonstrate for the first time that Ang II upregulates Gal-3 expression via increment in YAP nuclear localization in vascular endothelium, and that Gal-3 mediates endothelial dysfunction contributing to the development of hypertension., (© 2023.

Rationale: Chemotherapy is a common clinical strategy for cancer treatment. However, the accompanied cardiomyopathy renders cancer patients under risk of another life-threatening condition. Whereas Hippo pathway is known to play key roles in both cancerogenesis and heart disease, it remains unclear whether Hippo pathway activation mediates chemotherapy-induced cardiomyopathy. Methods and Results: In human breast cancer cells, doxorubicin (DOX) significantly induced upregulation of Hippo kinase Mst1, inhibitory phosphorylation of YAP, mitochondrial damage, reduced cell viability and increased apoptosis. Hippo pathway inactivation by Mst1-siRNA transfection effectively improved cell survival and mitigated mitochondrial damage and cell apoptosis. Another anti-cancer drug YAP inhibitor verteporfin also induced lower cancer cell viability, apoptosis and mitochondrial injury. Chronic treatment with DOX in vivo (4 mg/kg/week for 6 weeks) caused mitochondrial damage and dysfunction, oxidative stress and cardiac fibrosis, while acute DOX treatment (16 mg/kg single bolus) also induced myocardial oxidative stress and mitochondrial abnormalities. Chronic treatment with verteporfin (2 months) resulted in cardiomyopathy phenotypes comparable to that by chronic DOX regimen. In transgenic mice with cardiac overexpression of kinase-dead mutant Mst1 gene, these adverse cardiac effects of DOX were significantly attenuated relative to wild-type littermates. Conclusions: Anti-cancer action of both DOX and verteporfin is associated with Hippo pathway activation. Such action on cardiac Hippo pathway mediates mitochondrial damage and cardiomyopathy., Competing Interests: Competing Interests: The authors have declared that no competing interest exists., (© The author(s).)

Purpose: Hepatitis B virus (HBV) infection is such a global health problem that hundreds of millions of people are HBV carriers. Current anti-viral agents can inhibit HBV replication, but can hardly eradicate HBV. Cytosine-phosphate-guanosine (CpG) oligodeoxynucleotides (ODNs) are an adjuvant that can activate plasmacytoid dendritic cells (pDCs) and conventional dendritic cells (cDCs) to induce therapeutic immunity for HBV eradication. However, efficient delivery of CpG ODNs into pDCs and cDCs remains a challenge. In this study, we constructed a series of cationic lipid-assisted nanoparticles (CLANs) using different cationic lipids to screen an optimal nanoparticle for delivering CpG ODNs into pDCs and cDCs., Methods: We constructed different CLAN CpG using six cationic lipids and analyzed the cellular uptake of different CLAN CpG by pDCs and cDCs in vitro and in vivo, and further analyzed the efficiency of different CLAN CpG for activating pDCs and cDCs in both wild type mice and HBV-carrier mice., Results: We found that CLAN fabricated with 1,2-Dioleoyl-3-trimethylammonium propane (DOTAP) showed the highest efficiency for delivering CpG ODNs into pDCs and cDCs, resulting in strong therapeutic immunity in HBV-carrier mice. By using CLAN CpG as an immune adjuvant in combination with the injection of recombinant hepatitis B surface antigen (rHBsAg), HBV was successfully eradicated and the chronic liver inflammation in HBV-carrier mice was reduced., Conclusion: We screened an optimized CLAN fabricated with DOTAP for efficient delivery of CpG ODNs to pDCs and cDCs, which can act as a therapeutic vaccine adjuvant for treating HBV infection., (© 2022.

Objective: To summarize our hospital's single-center experience of and reflections on the treatment of chronic limb-threatening ischemia (CLTI) of lower limbs combined with diabetes in the past 5 years., Methods: We retrospectively analyzed cases of lower limb CLTI combined with diabetes diagnosed at our hospital from March 2017 to June 2021. The baseline data, surgical information, and follow-up results of the patients were collected. The primary outcome indicator was the patency rate of lower limb target artery within 1 year post-op, and the secondary indicators were the reoperation rate within 1 year post-op and the amputation rate within 1 year post-op., Results: A total of 89 patients with lower limb CLTI combined with diabetes were included in the study. A total of 85 patients underwent percutaneous transluminal angioplasty and the operation of 7 patients ended in failure, with the operation success rate reaching 91.76% (78/85). Three patients underwent femoral popliteal artery bypass grafting with artificial blood vessels and one patient underwent iliac femoral artery bypass grafting with artificial blood vessels, with the success rate of the operations reachign 100% (4/4). Among 78 patients who successfully underwent percutaneous transluminal angioplasty, the median follow-up time was 33 months (13, 64). Two patients died within one year after operation, with the post-op one-year survival rate being 97.44% (76/78). The post-op 1-year reoperation rate was 19.23% (15/78), the 1-year target vascular patency rate (deaths not included) was 85.53% (65/76), and the 1-year amputation rate was 3.85% (3/78). Among the patients who underwent bypass surgery, the follow-up period was 13-48 months. No thrombosis in or re-occlusion of the artificial blood vessels were observed during the follow-up period, and the artificial blood vessels remained unoccluded., Conclusion: Transluminal angioplasty has a relatively ideal rate of postoperative vascular patency. In addition, it is a minimally invasive procedure involving low perioperative risks and is performed under local anesthesia. Therefore, it can be used as the preferred treatment for patients with CLTI. On the other hand, bypass surgery has good long-term patency rate, but it involves higher perioperative risks and the procedure is more invasive. Therefore, bypass surgery can be used as an alternative when transluminal angioplasty ends in failure., (Copyright© by Editorial Board of Journal of Sichuan University (Medical Sciences).)

Defects can greatly promote the catalytic activity of a carbon-based electrocatalyst due to charge redistribution of its electroneutral π-conjugated structure. However, it is still a huge challenge to introduce enough defects into carbon-based materials to improve their catalytic activity. Herein, we report a new method for defect generation by the pyrolysis of the sulfur-nitrogen-containing coordination polymer [Zn(ptt) 2 ] n (ptt = 1-phenyl-1 H -tetrazole-5-thiol). A series of controlled experiments clearly demonstrates that the carbothermal reduction reaction of zinc sulfide with carbon at a high temperature plays an important role in creating defects and enhancing the catalytic activity for the oxygen reduction reaction (ORR) of the carbon-based materials. The ZnS/C-1100 with a high content of defects and a small number of ZnS nanoparticles exhibits excellent ORR electrocatalytic performances in alkaline media, in which the half-wave potential (0.894 V vs. RHE), stability, and methanol tolerance are all superior to that of a 20 wt% Pt/C catalyst. Moreover, the ZnS/C-1100 driven ZAB (zinc air battery) exhibits a stable discharge at 10 mA, a peak power density of 134 mW cm -2 and a cathode current density of 265 mA cm -2 , which are significantly better than that catalyzed by 20 wt% Pt/C under the same conditions. This research not only develops a new highly active catalyst, but also provides a new method for the preparation of defect-rich carbon materials.

Context: Stroke is an acute cerebrovascular disease and a neurological disorder that occurs due to a cerebral arterial embolism and rupture. Acute stroke is often accompanied by dysphagia, which reduces patients' intake of food and nutrients, decreases their nutritional status, and affects their quality of life., Objective: The study intended to identify the demographic and clinical characteristics of stroke patients with dysphagia and to explore the relationship of those characteristics to nutritional status and prognosis., Methods: The research team retrospectively collected the clinical data of patients to compare the nutritional status and prognoses of patients with different demographic and clinical characteristics., Setting: The study took place in the Department of Neurology at the First People's Hospital of Shenyang in Shenyang, China., Participants: Participants were 789 stroke patients with dysphagia who had been admitted to the general ward of the neurology departments of hospitals of Grade 3 or higher in Northeast China between January 2019 and September 2020. Based on the results of the Nutrition Risk Screening (NRS-2002) and Subjective Global Assessment (SGA) scales at baseline, participants were enrolled in this study., Outcome Measures: The outcomes were the correlations between participants' demographic and clinical characteristics and their nutritional statuses and prognoses. The Modified Rankin Scale (mRS) was used to evaluate the prognosis of the patients at seven days and three months after participants' enrollment in the study. Using the SPSS 26.0, a t test, chi-square test, and F test were performed to analyze and verify the presence of fundamental differences in baseline characteristics between participants with good nutrition and those with poor nutrition. Also, a statistical correlation analysis was performed., Results: The study showed that participants with different nutritional levels had statistically significant differences in the presence or absence of infections and body temperature and scores on the Standardized Swallowing Assessment (SSA) and National Institutes of Health Stroke Scale (NIHSS), with all P < .001. At baseline seven days after enrollment, the prognoses of participants were significantly different for different previous histories of stroke (P < .001), family history of stroke (P = .005), presence or absence of infections (P < .001), body temperature (P < .001), and SSA (P < .001) and NIHSS (P < .001) scale scores. At three months after enrollment, the prognoses of participants were significantly different for previous history of stroke (P = .003), different body temperatures (P < .001), presence or absence of infections(P < .001), and SSA (P < .001) and NIHSS (P < .001) scale scores. Age, gender, family history of stroke, smoking, alcohol consumption, previous history of stroke, education level, SSA scale score, NIHSS scale score, body mass index (BMI), body temperature, and infection were adjusted in the model. Nutritional status as classified by NRS-2002 and SGA was significantly correlated with prognosis (P < .001). The prognosis of stroke patients with dysphagia was associated with nutritional status by unconditional logistic regression., Conclusion: The prognosis of stroke patients with dysphagia is related to their nutritional status. A better nutritional status indicates the better prognosis, and vice versa. In clinical treatment, attention should be paid to use of a nutritional intervention.

Objective: Fear of recurrence is a common psychosocial sequela among patients with heart disease. Analyses of coronary heart disease, particularly in elderly patients, are relatively rare. This study aimed to investigate the current situation in this context, as well as the influencing fear factors concerning recurrence in elderly patients with coronary heart disease., Methods: A total of 200 elderly outpatients with coronary heart disease were recruited to participate in this survey from a tertiary hospital in Baoding (China). The questionnaires included items from the Disease Progression Simplified Scale, the Simplified Coping Style Questionnaire, and the Social Support Rating Scale (SSRS). Univariate and multivariate regression analyses were adopted to investigate the influencing factors on the fear of recurrence., Results: The fear of recurrence score in elderly patients with coronary heart disease was (38.46 ± 8.13), among which 119 cases (59.5%) scored higher than 34 points. The SSRS total average score was (34.89 ± 9.83) points. Positive coping style and social support were negatively correlated with the total score of recurrence fear (r =  - 0.621, - 0.413, both P < 0.001). There was a positive correlation between negative coping style and the total score of recurrence fear (r = 0.232, P < 0.001). Multiple linear regression analysis showed that the course of the disease, the number of disease recurrence cases, active coping, and social support were relevant factors in fear of recurrence (all P < 0.05)., Conclusion: The detection rate of fear of recurrence in elderly patients with coronary heart disease was relatively high but could be reduced by active interventions and enhancing social support., (© 2022.

Importance: Concurrent chemoradiotherapy has been the standard treatment for stage II nasopharyngeal carcinoma (NPC) based on data using 2-dimensional conventional radiotherapy. There is limited evidence for the role of chemotherapy with use of intensity-modulated radiation therapy (IMRT)., Objective: To assess whether concurrent chemotherapy can be safely omitted for patients with low-risk stage II/T3N0 NPC treated with IMRT., Design, Setting, and Participants: This multicenter, open-label, randomized, phase 3, noninferiority clinical trial was conducted at 5 Chinese hospitals, including 341 adult patients with low-risk NPC, defined as stage II/T3N0M0 without adverse features (all nodes <3 cm, no level IV/Vb nodes; no extranodal extension; Epstein-Barr virus DNA <4000 copies/mL), with enrollment between November 2015 and August 2020. The final date of follow-up was March 15, 2022., Interventions: Patients were randomly assigned to receive IMRT alone (n = 172) or concurrent chemoradiotherapy (IMRT with cisplatin, 100 mg/m2 every 3 weeks for 3 cycles [n = 169])., Main Outcomes and Measures: The primary end point was 3-year failure-free survival (time from randomization to any disease relapse or death), with a noninferiority margin of 10%. Secondary end points comprised overall survival, locoregional relapse-free survival, distant metastasis-free survival, adverse events, and health-related quality of life (QOL) measured by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ-C30; range, 0-100 points; minimum clinically important difference ≥10 for physical function, symptom control, or health-related QOL; higher score indicates better functioning and global health status or worse symptoms)., Results: Among 341 randomized patients (mean [SD] age, 48 [10] years; 30% women), 334 (98.0%) completed the trial. Median follow-up was 46 months (IQR, 34-58). Three-year failure-free survival was 90.5% for the IMRT-alone group vs 91.9% for the concurrent chemoradiotherapy group (difference, -1.4%; 1-sided 95% CI, -7.4% to ∞; P value for noninferiority, <.001). No significant differences were observed between groups in overall survival, locoregional relapse, or distant metastasis. The IMRT-alone group experienced a significantly lower incidence of grade 3 to 4 adverse events (17% vs 46%; difference, -29% [95% CI, -39% to -20%]), including hematologic toxicities (leukopenia, neutropenia) and nonhematologic toxicities (nausea, vomiting, anorexia, weight loss, mucositis). The IMRT-alone group had significantly better QOL scores during radiotherapy including the domains of global health status, social functioning, fatigue, nausea and vomiting, pain, insomnia, appetite loss, and constipation., Conclusions and Relevance: Among patients with low-risk NPC, treatment with IMRT alone resulted in 3-year failure-free survival that was not inferior to concurrent chemoradiotherapy., Trial Registration: ClinicalTrials.gov Identifier: NCT02633202.

Purpose: The recurrent/progressive glioblastoma multiforme (GBM) carries a dismal prognosis and the definitive treatment strategy has not yet been established. This study aimed to assess the efficacy and safety of apatinib in recurrent/progressive GBM patients. Materials and methods: The clinical data of 19 recurrent/progressive GBM patients who received apatinib treatment from November 2015 to December 2019 at Sun Yat-sen University Cancer Center were collected retrospectively in this study. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and treatment-related adverse events (AEs) were reviewed and assessed. Results: The overall ORR was 52.6%, and the DCR was 73.7%. Median PFS and OS were 5.1 and 10.4 months, respectively. The 6-month PFS and OS rates were 38.9% and 68.4%, respectively. The 12-month PFS and OS rates were 16.7% and 36.8%, respectively. The treatment-related toxicities were generally well-tolerated. The most common grade 3/4 AEs were hand-foot syndrome (36.8%) and hypertension (21.1%). Conclusion: Our study showed that apatinib therapy provided a better salvaging option for recurrent/progressive GBM patients and the toxicity was manageable., 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 Zhang, Du, Deng, Zheng, Yao, Wang, Yang and Wu.)

Objective: This study aimed to examine a novel method for prognostic evaluation of patients with oral squamous cell carcinoma (OSCC) based on the expression of heterogeneous nuclear ribonucleoprotein C (HNRNPC), YTH domain-binding protein 2 (YTHDF2), and methyltransferase 14 (METTL14)., Methods: We obtained the RNA sequence and clinical information of OSCC patients from The Cancer Genome Atlas database. An optical method was established by the least absolute shrinkage and selection operator Cox regression algorithm, which was used to calculate the risk score of every sample. In addition, all samples (n=239) were classified into high-risk (n=119) and low-risk (n=120) groups, and the overall survival (OS) time and clinical characteristics were compared between groups. Moreover, bioinformatics analysis was carried out. Gene set enrichment analysis was performed to investigate the signaling pathways of HNRNPC, YTHDF2, and METTL14., Results: The two groups showed significantly different OS time, tumor grades, tumor stages, and pathologic T stages (P<0.05). The receiver operating characteristic analysis identified that our method was effective and it was more accurate than use of age, gender, tumor grade, tumor stage, pathologic T stage, and pathologic N stage in OSCC prognostic prediction. Gene set enrichment analysis revealed that HNRNPC, YTHDF2, and METTL14 were mainly associated with ubiquitin-mediated proteolysis, cell cycle, RNA degradation, and spliceosome signaling pathways., Conclusion: The method based on the expression of HNRNPC, YTHDF2, and METTL14 can predict the prognosis of patients with OSCC independently, and its prognostic value is better than that of clinicopathological characteristic indicators., (© 2022.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically on the based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported. We previously reported significantly improved failure-free survival using gemcitabine plus cisplatin induction chemotherapy in locoregionally advanced nasopharyngeal carcinoma. Here, we present the final overall survival (OS) analysis. In this multicenter, randomized trial, patients were assigned to be treated with concurrent chemoradiotherapy alone (standard therapy, n = 238) or gemcitabine and cisplatin induction chemotherapy before concurrent chemoradiotherapy (n = 242). With a median follow-up of 69.8 months, the induction chemotherapy group had a significantly higher 5-year OS (87.9% v 78.8%, hazard ratio, 0.51 [95% CI 0.34 to 0.78]; P = .001) and a comparable risk of late toxicities (≥ grade 3, 11.3% v 11.4%). Notably, the depth of the tumor response to induction chemotherapy correlated significantly and positively with survival (complete response v partial response v stable/progressive disease, 5-year OS, 100% v 88.4% v 61.5%, P = .005). Besides, patients with a low pretreatment cell-free Epstein-Barr virus DNA load (< 4,000 copies/mL) might not benefit from induction chemotherapy (5-year OS, 90.6% v 91.4%, P = .77). In conclusion, induction chemotherapy before concurrent chemoradiotherapy improved OS significantly in patients with locally advanced nasopharyngeal carcinoma, without increasing the risk of late toxicities. Tumor response to induction chemotherapy and pretreatment cell-free Epstein-Barr virus DNA might be useful to guide individualized treatment.
