RESUMEN
OBJECTIVE: This study ascertained current status and influencing factors of readiness for hospital discharge (RHD) of lung cancer (LC) patients with enhanced recovery after surgery (ERAS) concept-guided postoperative management. METHODS: This study prospectively and consecutively included 217 LC patients who underwent whole-course ERAS concept-guided postoperative management at the Department of Thoracic Surgery of Guangzhou Institute of Cancer Research, the Affiliated Cancer Hospital, Guangzhou Medical University from November 2023 to April 2024. RHD, quality of discharge teaching (QDT), and social support (SS) were evaluated using RHDS, QDTS, and SSRS, followed by correlation analyses of RHD with the other 2 factors. The clinical baseline and pathological data were compared between the high and low RHD groups, and the characteristics showing statistical significance were assigned as independent variables for regression analysis with RHD as the dependent variable. RESULTS: RHD, QDT, and SS were above average among LC patients with ERAS concept-guided postoperative management, and RHD was positively correlated with both QDT and SS. Age, education level, self-care ability, number of admissions, and presence of drainage tubes were independent influence factors for RHD of LC patients with ERAS concept-guided postoperative management. CONCLUSION: In LC patients with ERAS concept-guided postoperative management, RHD may be improved by increasing QDT and SS and intervened by factors such as age, education level, self-care ability, number of admissions, and presence of drainage tubes.

Natural spider silk with extraordinary mechanical properties is typically spun from more than one type of spidroin. Although the main components of various spider silks have been widely studied, little is known about the molecular role of the minor silk components in spidroin self-assembly and fiber formation. Here, we show that the minor component of spider eggcase silk, TuSp2, not only accelerates self-assembly but remarkably promotes molecular chain alignment of spidroins upon physical shearing. NMR structure of the repetitive domain of TuSp2 reveals that its dimeric structure with unique charged surface serves as a platform to recruit different domains of the main eggcase component TuSp1. Artificial fiber spun from the complex between TuSp1 and TuSp2 minispidroins exhibits considerably higher strength and Young's modulus than its native counterpart. These results create a framework for rationally designing silk biomaterials based on distinct roles of silk components.

BACKGROUND: There are numerous symptoms related to cancer and its treatments that can affect the psychosomatic health and quality of life of patients with cancer. The use of electronic symptom management systems (ESMSs) can help patients with cancer monitor and manage their symptoms effectively, improving their health-related outcomes. However, patients' adhesion to ESMSs decreases over time, and little is known about their real experiences with them. Therefore, it is necessary to gain a deep understanding of patients' experiences with ESMSs. OBJECTIVE: The purpose of this systematic review was to synthesize qualitative studies on the experiences of patients with cancer using ESMSs. METHODS: A total of 12 electronic databases, including PubMed, Web of Science, Cochrane Library, EBSCOhost, Embase, PsycINFO, ProQuest, Scopus, Wanfang database, CNKI, CBM, and VIP, were searched to collect relevant studies from the earliest available record until January 2, 2024. Qualitative and mixed methods studies published in English or Chinese were included. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement checklist) and the ENTREQ (Enhancing Transparency in Reporting the Synthesis of Qualitative Research) statement were used to improve transparency in reporting the synthesis of the qualitative research. The Critical Appraisal Skills Program (CASP) checklist was used to appraise the methodological quality of the included studies, and a meta-synthesis was conducted to interpret and synthesize the findings. RESULTS: A total of 21 studies were included in the meta-synthesis. The experiences of patients with cancer using ESMSs were summarized into three major categories: (1) perceptions and attitudes toward ESMSs; (2) the value of ESMSs; and (3) barriers, requirements, and suggestions for ESMSs. Subsequently, 10 subcategories emerged from the 3 major categories. The meta-synthesis revealed that patients with cancer had both positive and negative experiences with ESMSs. In general, patients recognized the value of ESMSs in symptom assessment and management and were willing to use them, but they still encountered barriers and wanted them to be improved. CONCLUSIONS: This systematic review provides implications for developing future ESMSs that improve health-related outcomes for patients with cancer. Future research should focus on strengthening electronic equipment and technical support for ESMSs, improving their functional contents and participation forms, and developing personalized applications tailored to the specific needs and characteristics of patients with cancer.

Periodontitis is a chronic inflammatory destructive disease occurring in periodontal supporting tissues. Atherosclerosis(AS) is one of the most common cardiovascular diseases. Periodontitis can promote the development and progression of AS. Macrophage polarization is closely related to the development and progression of the above two diseases, respectively. The purpose of this animal study was to evaluate the effect of periodontitis on aortic lesions in atherosclerotic mice and the role of macrophage polarization in this process. 45 ApoE-/-male mice were randomly divided into three groups: control (NC), atherosclerosis (AS), and atherosclerosis with periodontitis (AS + PD). Micro CT, serological testing and pathological testing(hematoxylin-eosin staining, oil red O staining and Masson staining) were used for Evaluate the modeling situation. Immunohistochemistry(IHC) and immunofluorescence(IF) were performed to evaluate macrophage content and macrophage polarization in plaques. Cytokines associated with macrophage polarization were analyzed using quantitative real-time polymerase chain reaction(qRT-PCR) and enzyme-linked immunosorbent assay(Elisa). The expression of macrophages in plaques was sequentially elevated in the NC, AS, and AS + PD groups(P < 0.001). The expression of M1 and M1-related cytokines showed the same trend(P < 0.05). The expression of M2 and M2-related cytokines showed the opposite trend(P < 0.05). The rate of M1/M2 showed that AS + PD > AS > NC. Our preliminary data support that experimental periodontitis can increase the content of macrophage in aortic plaques to exacerbate AS. Meanwhile, experimental periodontitis can increase M1 macrophages, and decrease M2 macrophages, increasing M1/M2 in the plaque.

PURPOSE: To verify the effect and mechanism of baicalein in the treatment of periodontitis through network pharmacology, molecular docking and in vitro experiments. METHODS: Firstly, multiple databases were used to predict targets of baicalein and periodontitis. And the screened key target genes of baicalein for treating periodontitis were subjected to GO and KEGG analysis; then these targets were analyzed by molecular docking techniques. In vitro experiments including CCK-8, RT-qPCR, ELISA and Immunofluorescence were conducted to validate the efficacy of baicalein in treating periodontitis. RESULTS: Seventeen key targets were screened from the databases, GO and KEGG analysis of these targets revealed that baicalein may exert therapeutic effects through regulating TNF, PI3K-Akt, HIF-1 and other signaling pathways. Molecular docking analysis showed that baicalein has good binding potential to several targets. In vitro cellular assays showed that baicalein inhibited the expression of TNF-α, MMP-9, IL-6 and MCP1 in P.g-LPS-induced macrophages at both the mRNA and protein level. And the immunofluorescence intensity of iNOS, a marker of M1 type macrophages, which mainly secretes inflammatory factors, was significantly reduced. CONCLUSION: Baicalein has the characteristics and advantages of "multicomponent, multitarget, and multipathway" in the treatment of periodontitis. In vitro cellular assays further confirmed the inhibitory effect of baicalein on the secretion of inflammatory factors of macrophages in periodontitis models, providing a theoretical basis for further study of the material basis and molecular mechanism of baicalein in the treatment of periodontal diseases.

BACKGROUND AND OBJECTIVE: Periodontitis is immune inflammatory disease, atherosclerosis (AS) and chronic kidney disease (CKD) are two common systemic diseases. Periodontitis promotes AS and CKD, and CKD interacts with AS. The objective of this animal study was to evaluate the changes of kidney when periodontitis and atherosclerosis exist separately and the degenerative effects of periodontitis on the kidney in atherosclerotic mice. MATERIALS AND METHODS: A total of 40 male Apoe-/- mice were randomly divided into four groups: control (NC), periodontitis (PD), AS and AS with PD (AS + PD). AS was induced by high-fat diet feeding, and PD was induced by injection of Porphyromonas gingivalis-Lipopolysaccharide (P.g-LPS) (endotoxin suspension) into the buccal side of mouse maxillary molars. The right maxilla of mice was scanned with micro-CT to evaluate alveolar bone loss; aortic tissue was stained with HE and Oil-Red O to evaluate arterial plaque formation; serum was collected to detect the changes of blood lipids and serum renal function parameters (blood urea nitrogen [BUN], serum creatinine [Scr]); renal histopathological changes were evaluated by HE staining (glomerular and tubular damage scores), PAS staining (glomerular Mesangial matrix index) and Masson staining (percentage of renal fibrosis area); qRT-PCR and ELISA were used to evaluate the expression of renal inflammatory cytokines (tumor necrosis factor-α, Interleukin-1ß, neutrophil surface marker Ly6G). RESULTS: The amount of alveolar bone loss: PD group was significantly higher than NC group (p < .05); AS + PD group was higher than PD group, the difference was not statistically significant. Atherosclerotic plaque formation and serum lipid changes: AS group were significantly worse than NC group (p < .05), and AS + PD group were worse than AS group. The results of the corresponding qualitative and quantitative analyses of kidney tissue in experimental animals gradually deteriorated in the NC group, PD group, AS group and AS + PD group and worsened sequentially. Renal function parameters: the content of BUN in AS group was higher than that in PD group, the difference was not statistically significant; Scr in AS group was significantly higher than that in PD group (p < .05); the contents of BUN and Scr in AS + PD group were higher than those in AS group, the difference was not statistically significant. Glomerular and tubular damage scores: AS group were higher than PD group, the difference was not statistically significant; AS + PD group were significantly higher than AS group (p < .001). The ratio of glomerular mesangial matrix to glomerular area and the percentage of renal fibrosis area: AS group were significantly higher than PD group (p < .001), and AS + PD group were significantly higher than AS group (p < .001). Expression of inflammatory cytokines: AS group was higher than PD group, the difference was not statistically significant; AS + PD group was significantly higher than AS group (p < .05). CONCLUSION: Both PD and AS can aggravate the inflammatory stress of kidney tissue and cause the damage of kidney tissue, and the inflammatory increase and damage effect of AS is stronger; PD can promote kidney damage of atherosclerotic mice by aggravating the renal inflammation in atherosclerotic mice; renal function parameters were not completely synchronized with the changes of renal inflammation and histopathology in each group of mice; PD can promote AS, periodontal inflammation in mice with AS is more severe, and the special changes of blood lipids in mice with AS are closely related to the above results.

Receptor-interacting protein kinase 2 (RIPK2) is an essential protein kinase mediating signal transduction by NOD1 and NOD2, which play an important role in regulating immune signalling. In this study, we designed and synthesised a novel series of 4-aminoquinoline-based derivatives as RIPK2 inhibitors. In vitro, compound 14 exhibited high affinity (IC50 = 5.1 ± 1.6 nM) and excellent selectivity to RIPK2 showing in a dendrogram view of the human kinome phylogenetic tree. Bearing favourable lipophilicity and eligible lipophilic ligand efficiency (LipE), compound 14 was selected to investigate cellular anti-inflammatory effect and was identified as a potent inhibitor to reduce the secretion of MDP-induced TNF-α with a dose-dependent manner. Moreover, compound 14 showed moderate stability in human liver microsome. Given these promising results, compound 14 could serve as a favourable inhibitor of RIPK2 for further physiological and biochemical research so as to be used in therapeutic treatment.

sABSTRACTTANK-binding kinase 1 (TBK1), a noncanonical member of the inhibitor-kappaB kinases (IKKs) family, plays a vital role in coordinating the signalling pathways of innate immunity, involving in the process of neuroinflammation, autophagy, and oncogenesis. In current study, based on rational drug design strategy, we discovered a series of 1H-pyrazolo[3,4-b]pyridine derivatives as potent TBK1 inhibitors and dissected the structure-activity relationships (SARs). Through the several rounds of optimisation, compound 15y stood out as a potent inhibitor on TBK1 with an IC50 value of 0.2 nM and also displayed good selectivity. The mRNA detection of TBK1 downstream genes showed that compound 15y effectively inhibited TBK1 downstream IFN signalling in stimulated THP-1 and RAW264.7 cells. Meanwhile, compound 15y exhibited a micromolar antiproliferation effect on A172, U87MG, A375, A2058, and Panc0504 cell lines. Together, current results provided a promising TBK1 inhibitor 15y as lead compound for immune- and cancer-related drug discovery.

WD40 is a ubiquitous domain presented in at least 361 human proteins and acts as scaffold to form protein complexes. Among them, WDR5 protein is an important mediator in several protein complexes to exert its functions in histone modification and chromatin remodeling. Therefore, it was considered as a promising epigenetic target involving in anti-cancer drug development. In view of the protein-protein interaction nature of WDR5, we initialized a campaign to discover new peptide-mimic inhibitors of WDR5. In current study, we utilized the phage display technique and screened with a disulfide-based cyclic peptide phage library. Five rounds of biopanning were performed and isolated clones were sequenced. By analyzing the sequences, total five peptides were synthesized for binding assay. The four peptides are shown to have the moderate binding affinity. Finally, the detailed binding interactions were revealed by solving a WDR5-peptide cocrystal structure.

In virtualized sensor networks, virtual machines (VMs) share the same hardware for sensing service consolidation and saving power. For those VMs that reside in the same hardware, frequent interdomain data transfers are invoked for data analytics, and sensor collaboration and actuation. Traditional ways of interdomain communications are based on virtual network interfaces of bilateral VMs for data sending and receiving. Since these network communications use TCP/IP (Transmission Control Protocol/Internet Protocol) stacks, they result in lengthy communication paths and frequent kernel interactions, which deteriorate the I/O (Input/Output) performance of involved VMs. In this paper, we propose an optimized interdomain communication approach based on shared memory to improve the interdomain communication performance of multiple VMs residing in the same sensor hardware. In our approach, the sending data are shared in memory pages maintained by the hypervisor, and the data are not transferred through the virtual network interface via a TCP/IP stack. To avoid security trapping, the shared data are mapped in the user space of each VM involved in the communication, therefore reducing tedious system calls and frequent kernel context switches. In implementation, the shared memory is created by a customized shared-device kernel module that has bidirectional event channels between both communicating VMs. For performance optimization, we use state flags in a circular buffer to reduce wait-and-notify operations and system calls during communications. Experimental results show that our proposed approach can provide five times higher throughput and 2.5 times less latency than traditional TCP/IP communication via a virtual network interface.
RESUMEN
Purpose: With the rapid development of immunotherapy, cancer treatment has entered a new phase. Medical imaging, as a primary diagnostic method, is closely related to cancer immunotherapy. However, until now, there has been no systematic bibliometric analysis of the state of this field. Therefore, the main purpose of this article is to clarify the past research trajectory, summarize current research hotspots, reveal dynamic scientific developments, and explore future research directions. Patients and Methods: A comprehensive search was conducted on the Web of Science Core Collection (WoSCC) database to identify publications related to immunotherapy specifically for the medical imaging of carcinoma. The search spanned the period from the year 2003 to 2023. Several analytical tools were employed. These included CiteSpace (6.2.4), and the Microsoft Office Excel (2016). Results: By searching the database, a total of 704 English articles published between 2003 and 2023 were obtained. We have observed a rapid increase in the number of publications since 2018. The two most active countries are the United States (n=265) and China (n=170). Pittock, Sean J and Abu-sbeih, Hamzah are very concerned about the relationship between cancer immunotherapy and medical images and have published more academic papers (n = 5; n = 4). Among the top 10 co-cited authors, Topalian Sl (n=43) cited ranked first, followed by Graus F (n=40) cited. According to clustering, timeline, and burst word analysis, the results show that the current research focus is on "MRI", "deep learning", "tumor microenvironment" and so on. Conclusion: Medical imaging and cancer immunotherapy are hot topics. The United States is the country with the most publications and the greatest influence in this field, followed by China. "MRI", "PET/PET-CT", "deep learning", "immune-related adverse events" and "tumor microenvironment" are currently hot research topics and potential targets.
RESUMEN
PURPOSE: The aim of this study was to examine the level of health-related quality of life (HRQOL) of lung cancer patients receiving immune checkpoint inhibitors (ICIs) and analyze its influencing factors. METHOD: A cross-sectional study was conducted. From April 2022 to March 2023, 560 lung cancer patients receiving ICIs at three medical bases in Guangzhou, China were recruited using a convenient sampling method. A general information questionnaire, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), the Social Support Rating Scale (SSRS) and the Medical Coping Modes Questionnaire (MCMQ) were used for collecting data on sociodemographic and clinical characteristics, HRQOL, social support and medical coping mode. A descriptive analysis was conducted to describe HRQOL. Multiple regression analysis was applied to determine the factors influencing HRQOL. RESULTS: For lung cancer patients receiving ICIs, the mean score of HRQOL was 59.21 ± 19.86. Multivariate analysis indicated that acceptance-resignation coping mode (ß = -0.37, P < 0.01), Eastern Cooperative Oncology Group (ECOG) score (ß = -0.35, P < 0.01), combination of chemotherapy and/or bevacizumab (ß = -0.14, P < 0.01), and subjective support (ß = 0.07, P = 0.04) all contributed to 42.7% of the variance in HRQOL of the patients receiving ICIs. CONCLUSIONS: It is imperative to address and resolve the HRQOL issue for lung cancer patients receiving ICIs. The findings suggest nurse practitioners should be aware of a variety of factors that influence HRQOL and provide tailored inventions to patients as early as possible to help them achieve better HRQOL.

Poor oral health is the most immediate and overlooked hazard of methamphetamine abuse in humans. Previous studies have reported methamphetamine-associated alterations in saliva microbiota, but the cause of methamphetamine-induced alterations in the oral microenvironment remains unclear. The present study aimed to investigate the alterations in dental plaque microbiota in methamphetamine users, and to explore their relationship with local immune inflammation in the oral cavity. This may provide new ideas on the development of methamphetamine-related oral microenvironment changes. Questionnaires and samples were obtained from 30 female methamphetamine users and 15 sex- and age-matched healthy controls. Microbial profiles of supragingival dental plaque were analyzed using 16S rRNA gene sequencing. Inflammatory factors in saliva were measured using enzyme-linked immunosorbent assay. Methamphetamine users had worse oral self-evaluation. Compared with healthy controls, methamphetamine users showed no differences in oral dental plaque microbial diversity but exhibited differences in the relative abundance of several microbial taxa. At the phylum level, a higher abundance of Proteobacteria and a lower abundance of Firmicutes were detected in methamphetamine users. Moreover, function prediction using the MetaCyc database showed that 33 pathways were significantly upregulated in methamphetamine users; Only the glycolytic (Pyrococcus) pathway was enriched in the C group. Importantly, salivary inflammatory factors showed complex significant associations with bacterial genera in methamphetamine users. Specifically, the genus Neisseria was positively correlated with IL-17 levels in saliva, and both were high in methamphetamine users. In contrast, the genus Streptococcus, with a lower abundance, was positively correlated with lower IL-10 levels. Overall, This study is the first to provide evidence for a link between altered dental plaque microbiota and salivary inflammation in methamphetamine users. Further elucidation of the interactions between methamphetamine use and oral microenvironment would be beneficial for appropriate interventions to improve oral health.

Spider silk is renowned for its excellent mechanical properties. Among six types of silk and one silk glue produced by different abdominal glands for various purposes, tubuliform (eggcase) silk is unique due to its high serine and low glycine content. Eggcase silk is spun from at least two spidroins, tubuliform spidroin 1 (TuSp1) and TuSp2. TuSp1 and TuSp2 were identified as the major and the minor components in tubuliform glands, respectively. TuSp2 consists of multiple repetitive (RP) domains with short terminal tails and shares very limited homology to all known spidroins. Here we report backbone and side chain resonance assignments of TuSp2-RP as a basis for structural and functional studies on eggcase silk formation.

Spider silk has remarkable physical and biocompatible properties. Investigation of structure-function relationship and self-assembly process of spidroins is necessary for uncovering the mechanism of silk fiber formation. Nevertheless, how the terminal domains initiate self-assembly of soluble tubuliform spidroins to form solid eggcase silk is still not fully understood. Here we investigate the roles of both terminal domains of tubuliform spidroin 1 (TuSp1) in the silk fiber formation. We found that interactions among the terminal domains drive rapid TuSp1 self-assembly and fiber formation, which is insensitive to pH changes from 6.0 to 7.0. These interactions also contribute to the spidroin chain alignment in fiber formation upon shear-force exposure. Structural analysis and site-directed mutagenesis identified eight critical surface-exposed residues involved in hydrophobic interactions among terminal domains. Spidroins with single-point mutations of these residues fail to form intermediate micelle-like structures. The structural docking model indicates that multiple terminal domains of TuSp1 may interact with each other based on hydrophobic interactions and surface complementarity, which may lead to forming the surface of the micelle-like structure. Our results provide new insights into the structural mechanism of eggcase silk formation and the basis for designing and producing novel biomaterials derived from spider eggcase silk.

Critical care medicine is a medical specialty engaging the diagnosis and treatment of critically ill patients who have or are likely to have life-threatening organ failure. Sepsis, a life-threatening condition that arises when the body responds to infection, is currently the major cause of death in intensive care units (ICU). Although progress has been made in understanding the pathophysiology of sepsis, many drawbacks in sepsis treatment remains unresolved. For example, antimicrobial resistance, controversial of glucocorticoids use, prolonged duration of ICU care and the subsequent high cost of the treatment. Recent years have witnessed a growing trend of applying traditional Chinese medicine (TCM) in sepsis management. The TCM application emphasizes use of herbal formulation to balance immune responses to infection, which include clearing heat and toxin, promoting blood circulation and removing its stasis, enhancing gastrointestinal function, and strengthening body resistance. In this paper, we will provide an overview of the current status of Chinese herbal formulations, single herbs, and isolated compounds, as an add-on therapy to the standard Western treatment in the sepsis management. With the current trajectory of worldwide pandemic eruption of newly identified Coronavirus Disease-2019 (COVID-19), the adjuvant TCM therapy can be used in the ICU to treat critically ill patients infected with the novel coronavirus.

OBJECTIVE: This study aims to explore factors affecting the dental aesthetic social psychology of patients with skeletal malocclusion and to measure the relationship between the objective orthodontic requirements and the subjective treatment requirements of patients. This work provides a reference for doctors to measure patients' orthodontic treatment needs. METHODS: Adult patients with skeletal malocclusion were chosen as the research object. Questionnaire survey was used to analyze factors influencing the psychosocial impact of dental aesthetics questionnaire (PIDAQ), index of orthodontic treatment need (IOTN), and Eysenck personality questionnaire-revised short scale for Chinese (EPQ-RSC). The relationship among PIDAQ, IOTN, EPQ-RSC, and treatment options was also evaluated. RESULTS: Seventy-two valid questionnaires were collected from adult patients with skeletal malocclusion. 1) The PIDAQ scores significantly differed among different occupations (P<0.05) but were not affected by other general conditions such as gender and age. 2) Patients of different dental health component (DHC) grade and ages had different AC self-assessment scores (P<0.01, P<0.05). The AC self-assessment score was positively correlated with the PIDAQ score (P<0.05). 3) Males accounted for a higher proportion of patients who received treatment. Younger patients (18-28 years old) were more likely to receive treat-ment when their own dental aesthetics were poor. People with the higher monthly expenditure accounted for the larger proportion of surgical patients. 4) The PIDAQ score had no significant effects on the choice of opera-tion (P>0.05). People with low educational level were more likely to receive surgery if their psychosocial impacts of dental aes-thetics were serious. 5) The score of psychoticism scale of EPQ-RSC and the educa-tional level had a mutual influence on the PIDAQ score (P<0.01). Moreover, the neuroticism scale and AC self-assessment scores had a mutual influence on the PIDAQ score (P<0.05). However, this study did not find a correlation between personality traits and treatment options. CONCLUSIONS: Many factors, such as personal natural conditions, subjective aesthetic evaluation of teeth, and psychosocial impacts of dental aesthetics, affect patients' treatment options. Personality characteristics can play a certain role in dental aesthetics social psychology.
