Sorafenib safety evaluation: Real-world analysis of adverse events from the FAERS database.

Background: Sorafenib is approved for the targeted therapy of cancers such as liver cancer and renal cancer. Given its widespread use, drug-related adverse events have received attention, and the post-marketing regulatory link is crucial. Objective: By using the FAERS database to mine the adverse events (AEs) related to sorafenib, comparing the association intensity of key AEs, and exploring potential drug-related AEs, it provides a reference for clinical medication. Methods: Collect ADE data related to sorafenib in the FAERS database from 2006 to 2023. Standardize the data, and map adverse events to system organ classes and preferred terms. Analyze using various signal quantification techniques such as ROR, PRR, BCPNN, and MGPS. Results: Among 18,520 adverse event reports (AERs) where sorafenib was the primary suspected drug, a total of 390 preferred terms (PTs) of adverse reactions were identified, covering 24 different system organ classes (SOCs). Specifically, the adverse events of sorafenib mainly involve the digestive system, skin and subcutaneous tissue, as well as non-specific physical discomfort including infection and injury. Among them, digestive system symptoms and skin toxicity are typical adverse reactions of sorafenib. We also observed uncommon but clearly strong AE signals, such as chloracne (n = 3, ROR 1756.39, PRR 1756.32, IC 8.78, EBGM 439.83), low-differentiated thyroid cancer (n = 4, ROR 585.47, PRR 585.44, IC 8.2, EBGM 293.22). It is worth noting that palmar-plantar erythrodysaesthesia syndrome (n = 2109, ROR 73.98, PRR 72.03, IC 6.01, EBGM 64.25) and hepatic encephalopathy (n = 457, ROR 37.44, PRR 37.23, IC 5.13, EBGM 35.07) have a higher incidence and signal intensity. In addition, we also observed some adverse events not mentioned in the official drug instructions, such as vitamin K deficiency or increased protein induced by antagonist II (PIVKA-II), abnormal alpha-fetoprotein, tumor metastasis, and splenic atrophy. Conclusion: Sorafenib carries the risk of various adverse reactions while providing therapeutic effects. In clinical applications, physicians should closely monitor the occurrence of digestive system reactions, skin lesions, endocrine system lesions, as well as injuries, infections, and other events.

NIR-Activable Charge Transfer Agents for Synergistic Photoimmunotherapy.

The combination of photothermal therapy (PTT) and photodynamic therapy (PDT) has become an attractive tumor treatment modality, yet the facile design of photoimmunotheranostic agents with efficient near infrared (NIR) light-absorbing and immune- activating capabilities remains a tremendous challenge. Herein, we developed a NIR-activable organic charge transfer complex (CTC), with perylene (PER) as the electron donor and 4,5,9,10-tetrabromoisochromeno [6,5,4-def]isochromene-1,3,6,8-tetraone (Br4NDI) as the electron acceptor. Through further supramolecular assembly, the PER-Br4NDI nanoparticle (PBND NP) for spatiotemporally controlled photoimmunotherapy was constructed. The PBND NP exhibits superb NIR absorption, robust intermolecular charge transfer, and enhanced intersystem crossing. Upon NIR photoirradiation, the PBND NP effectively exerts photothermal and photodynamic effects with a remarkable photothermal conversion efficiency of 63.5% and a high reactive oxygen species generation capability, which not only directly ablates primary tumors, but also dramatically suppresses distant tumor growth via promoted immunogenic cell death. Moreover, programmed cell death protein 1 antibody acts synergistically to block immune evasion and ultimately enhances cancer treatment efficacy. This work therefore sheds light on the design of organic CTCs for synergistic photoimmunotherapy.

Cofrogliptin once every 2 weeks as add-on therapy to metformin versus daily linagliptin in patients with type 2 diabetes in China: A randomized, double-blind, non-inferiority trial.

AIM: We evaluated the efficacy and safety of cofrogliptin, a novel dipeptidyl peptidase-4 inhibitor taken once every 2 weeks (Q2W), compared with linagliptin (taken daily) in patients with type 2 diabetes inadequately controlled on metformin in China. MATERIALS AND METHODS: In this phase 3 randomized, double-blind, active-controlled, multicentre study, patients were randomly assigned 1:1:1 to receive cofrogliptin 10 mg Q2W, cofrogliptin 25 mg Q2W, or linagliptin 5 mg daily, all as an add-on treatment to metformin, for 24 weeks. Eligible patients could enter an open-label extension period and receive cofrogliptin 25 mg Q2W for an additional 28 weeks. The primary endpoint was change in glycated haemoglobin from baseline to 24 weeks, with a non-inferiority margin of 0.4% for cofrogliptin versus linagliptin treatment. RESULTS: Overall, 465 patients entered the 24-week treatment period (median age: 57.0 years). The least-squares mean (standard error) change in glycated haemoglobin from baseline to week 24 was -0.96 (0.063), -0.99 (0.064) and -1.07 (0.065) for the cofrogliptin 10 mg, cofrogliptin 25 mg and linagliptin 5 mg groups, respectively. The between-group difference met the predefined margin for non-inferiority of cofrogliptin (10 and 25 mg) versus linagliptin treatment. The incidence of common adverse events (≥5% patients) during the 24-week treatment period was similar between treatment groups. There were no serious hypoglycaemic events. CONCLUSION: In Chinese patients with type 2 diabetes inadequately controlled on metformin, the glucose-lowering effect of cofrogliptin (Q2W) was non-inferior to linagliptin (daily), with a similar safety profile maintained over 52 weeks of treatment.

Unveiling axolotl transcriptome for tissue regeneration with high-resolution annotation via long-read sequencing.

Axolotls are known for their remarkable regeneration ability. Exploring their transcriptome provides insight into regenerative mechanisms. However, the current annotation of the axolotl transcriptome is limited, leaving the role of unannotated transcripts in regeneration unknown. To discourse this challenge, we exploited long-read sequencing technology, which enables direct observation of full-length RNA transcripts, greatly enhancing the coverage and accuracy of axolotl transcriptome annotation. By utilizing this method, we identified 222 novel gene loci and 4775 novel transcripts, which were quantified using short-read sequencing data. Through the inclusive analysis, we discovered novel homologs, potential functional proteins, noncoding RNAs, and alternative splicing events in key regeneration pathways. In particular, we identified novel transcripts with high protein-coding potential implicated in cell cycle regulation and musculoskeletal development, and regeneration were identified. Interestingly, alternative splice variants were also detected across diverse pathways critical to regeneration. This specifies that these novel transcripts potentially play vital roles underpinning the robust regenerative capacities of axolotls. Single-cell transcriptomic analysis further revealed these isoforms to predominantly exist in axolotl limb chondrocytes and mature tissue cell populations. Overall, the findings significantly advanced consideration of the axolotl transcriptome and provided a new perspective for understanding the mechanisms of regenerative abilities of axolotls.

CO-Free Aminocarbonylation of Terminal Alkynes Catalyzed by Synergistic Effect From Metal-Organic Frameworks.

Incorporation of CO into substrates to construct high-value carbonyl compounds is an intensive industrial carbonylation procedure, however, high toxicity and wide explosion limits (12.5-74.0 vol% in air) of CO limit its application in industrial production. The development of a CO-free catalytic system for carbonylation is one of ideal methods, but full of challenge. Herein, this study reports the CO-free aminocarbonylation conversion of terminal alkynes synergistically catalyzed by a unique Co(ІІ)/Ag(І) metal-organic framework (MOF), in which the combination of isocyanides and O2 is employed as safe and green source of aminocarbonyl. This reaction has broad substrate applicability in terminal alkyne and isocyanides components with 100% atom economy. The bimetal MOF catalyst can be recycled at least five times without substantial loss of catalytic activities. Mechanistic investigations demonstrate that the synergistic effect between Ag(I) and Co(II) sites can efficiently activate terminal alkyne and isocyanides, respectively. Free radical capture experiments, FT-IR analysis and theoretical explorations further reveal that terminal alkynes and isocyanides can be catalytically transformed into an anionic intermediate through heterolysis pathways. This work provides secure and practical access to carbonylation as well as a new approach to aminocarbonylation of terminal alkynes.

Structural basis for the type I-F Cas8-HNH system.

The Cas3 nuclease is utilized by canonical type I CRISPR-Cas systems for processive target DNA degradation, while a newly identified type I-F CRISPR variant employs an HNH nuclease domain from the natural fusion Cas8-HNH protein for precise target cleavage both in vitro and in human cells. Here, we report multiple cryo-electron microscopy structures of the type I-F Cas8-HNH system at different functional states. The Cas8-HNH Cascade complex adopts an overall G-shaped architecture, with the HNH domain occupying the C-terminal helical bundle domain (HB) of the Cas8 protein in canonical type I systems. The Linker region connecting Cas8-NTD and HNH domains adopts a rigid conformation and interacts with the Cas7.6 subunit, enabling the HNH domain to be in a functional position. The full R-loop formation displaces the HNH domain away from the Cas6 subunit, thus activating the target DNA cleavage. Importantly, our results demonstrate that precise target cleavage is dictated by a C-terminal helix of the HNH domain. Together, our work not only delineates the structural basis for target recognition and activation of the type I-F Cas8-HNH system, but also guides further developments leveraging this system for precise DNA editing.

Multi-dimensional epidemiology and informatics data on COVID-19 wave at the end of zero COVID policy in China.

Background: China exited strict Zero-COVID policy with a surge in Omicron variant infections in December 2022. Given China's pandemic policy and population immunity, employing Baidu Index (BDI) to analyze the evolving disease landscape and estimate the nationwide pneumonia hospitalizations in the post Zero COVID period, validated by hospital data, holds informative potential for future outbreaks. Methods: Retrospective observational analyses were conducted at the conclusion of the Zero-COVID policy, integrating internet search data alongside offline records. Methodologies employed were multidimensional, encompassing lagged Spearman correlation analysis, growth rate assessments, independent sample T-tests, Granger causality examinations, and Bayesian structural time series (BSTS) models for comprehensive data scrutiny. Results: Various diseases exhibited a notable upsurge in the BDI after the policy change, consistent with the broader trajectory of the COVID-19 pandemic. Robust connections emerged between COVID-19 and diverse health conditions, predominantly impacting the respiratory, circulatory, ophthalmological, and neurological domains. Notably, 34 diseases displayed a relatively high correlation (r > 0.5) with COVID-19. Among these, 12 exhibited a growth rate exceeding 50% post-policy transition, with myocarditis escalating by 1,708% and pneumonia by 1,332%. In these 34 diseases, causal relationships have been confirmed for 23 of them, while 28 garnered validation from hospital-based evidence. Notably, 19 diseases obtained concurrent validation from both Granger causality and hospital-based data. Finally, the BSTS models approximated approximately 4,332,655 inpatients diagnosed with pneumonia nationwide during the 2 months subsequent to the policy relaxation. Conclusion: This investigation elucidated substantial associations between COVID-19 and respiratory, circulatory, ophthalmological, and neurological disorders. The outcomes from comprehensive multi-dimensional cross-over studies notably augmented the robustness of our comprehension of COVID-19's disease spectrum, advocating for the prospective utility of internet-derived data. Our research highlights the potential of Internet behavior in predicting pandemic-related syndromes, emphasizing its importance for public health strategies, resource allocation, and preparedness for future outbreaks.

External validation of different predictive scores for symptomatic intracranial hemorrhage after intravenous thrombolysis in Asian stroke patients.

OBJECTIVE: This study aimed to externally validate different predictive scores for symptomatic intracranial hemorrhage (SICH) after intravenous thrombolysis (IVT), with a particular focus on their predictive abilities in Asian stroke patients. METHODS: We retrospectively enrolled stroke patients who received a standard dose of alteplase within 4.5 hours from symptom onset at the First Affiliated Hospital of Dalian Medical University from July 2010 to August 2023. SICH was defined as the hemorrhagic transformation detected on the head CT scan completed within 48 h post-IVT, accompanied by a clinical deterioration of at least a 4-point increase in NIHSS score. Predictive abilities of the HAT, MSS, SEDAN, SPAN-100, and GRASPS scores were tested. Discrimination and calibration were performed using the area under the receiver operating characteristic curve (ROC-AUC), DeLong test, and Hosmer-Lemeshow (H-L) goodness-of-fit test. RESULTS: The study included 1007 stroke patients, of whom 31 (3.08 %) developed SICH. ROC-AUCs for predicting SICH were: 0.796 (95 %CI: 0.726-0.866) for the GRASPS score, 0.724 (95 %CI: 0.644-0.804) for the MSS score, 0.715 (95 %CI: 0.619-0.811) for the SEDAN score, 0.714 (95 %CI: 0.611-0.817) for the HAT score, and 0.605 (95 %CI: 0.491-0.720) for the SPAN-100 score (all P < 0.05). DeLong tests showed that the GRASPS score demonstrated significantly better discrimination than the MSS score (P = 0.010), the SEDAN score (P = 0.009), the HAT score (P = 0.049), and the SPAN-100 score (P = 0.000). H-L tests indicated good calibrations which were ranked HAT > SEDAN > MSS > SPAN-100 > GRASPS scores. CONCLUSION: The GRASPS score showed reasonable predictive ability for SICH, indicating its potential utility for Asian stroke patients receiving IVT.

Bone controls browning of white adipose tissue and protects from diet-induced obesity through Schnurri-3-regulated SLIT2 secretion.

The skeleton has been suggested to function as an endocrine organ controlling whole organism energy balance, however the mediators of this effect and their molecular links remain unclear. Here, utilizing Schnurri-3-/- (Shn3-/-) mice with augmented osteoblast activity, we show Shn3-/-mice display resistance against diet-induced obesity and enhanced white adipose tissue (WAT) browning. Conditional deletion of Shn3 in osteoblasts but not adipocytes recapitulates lean phenotype of Shn3-/-mice, indicating this phenotype is driven by skeleton. We further demonstrate osteoblasts lacking Shn3 can secrete cytokines to promote WAT browning. Among them, we identify a C-terminal fragment of SLIT2 (SLIT2-C), primarily secreted by osteoblasts, as a Shn3-regulated osteokine that mediates WAT browning. Lastly, AAV-mediated Shn3 silencing phenocopies the lean phenotype and augmented glucose metabolism. Altogether, our findings establish a novel bone-fat signaling axis via SHN3 regulated SLIT2-C production in osteoblasts, offering a potential therapeutic target to address both osteoporosis and metabolic syndrome.

Stereoselective benzylic C(sp3)-H alkenylation enabled by metallaphotoredox catalysis.

Selective activation of the benzylic C(sp3)-H bond is pivotal for the construction of complex organic frameworks. Achieving precise selectivity among C-H bonds with comparable energetic and steric profiles remains a profound synthetic challenge. Herein, we unveil a site- and stereoselective benzylic C(sp3)-H alkenylation utilizing metallaphotoredox catalysis. Various linear and cyclic (Z)-all-carbon tri- and tetrasubstituted olefins can be smoothly obtained. This strategy can be applied to complex substrates with multiple benzylic sites, previously deemed unsuitable due to the uncontrollable site-selectivity. In addition, sensitive functional groups such as terminal alkenyl and TMS groups are compatible under the mild conditions. The exceptional site-selectivity and broad substrate compatibility are attributed to the visible-light catalyzed relay electron transfer-proton transfer process. More importantly, we have extended this methodology to achieve enantioselective benzylic C(sp3)-H alkenylation, producing highly enantioenriched products. The applicability and scalability of our protocol are further validated through late-stage functionalization of complex structures and gram-scale operations, underscoring its practicality and robustness.

Counterion Distribution in the Stern Layer on Charged Surfaces.

Counterion adsorption at the solid-liquid interface affects numerous applications. However, the counterion adsorption density in the Stern layer has remained poorly evaluated. Here we report the direct determination of surface charge density at the shear plane between the Stern layer and the diffuse layer. By the Grahame equation extension and streaming current measurements for different solid surfaces in different aqueous electrolytes, we are able to obtain the counterion adsorption density in the Stern layer, which is mainly related to the surface charge density but is less affected by the bulk ion concentration. The charge inversion concentration is further found to be sensitive to the ion type and ion valence rather than to the charged surface, which is attributed to the ionic competitive adsorption and ion-ion correlations. Our findings offer a framework for understanding ion distribution in many physical and chemical processes where the Stern layer is ubiquitous.

Employing conductive porous hydrogen-bonded organic framework for ultrasensitive detection of peanut allergen Ara h1.

Peanut allergy has garnered worldwide attention due to its high incidence rate and severe symptoms, stimulating the demand for the ultrasensitive detection method of peanut allergen. Herein, we successfully developed a novel electrochemical aptasensor for ultrasensitive detection Ara h1, a major allergenic protein present in peanuts. A conductive nickel atoms Anchored Hydrogen-Bonded Organic Frameworks (PFC-73-Ni) were utilized as excellent electrocatalysts toward hydroquinone (HQ) oxidation to generate a readable current signal. The developed electrochemical aptasensor offers wide linear range (1-120 nM) and low detection limit (0.26 nM) for Ara h1. This method demonstrated a recovery rate ranging from 95.00% to 107.42% in standard addition detection of non-peanut food samples. Additionally, the developed electrochemical method was validated with actual samples and demonstrated good consistency with the results obtained from a commercial ELISA kit. This indicates that the established Ara h1 detection method is a promising tool for peanut allergy prevention.

Dual-Level Reactive Oxygen Species Amplifier for Enhanced Photothermal-Chemodynamic Therapy.

Chemodynamic therapy is an appealing modality in cancer treatment. However, its therapeutic effectiveness is impeded by insufficient catalytic efficiency and overexpression of glutathione (GSH) at the tumor site. In this study, a poly(o-phenylenediamine) (PoPD)@copper sulfide (CuS) nanoplatform was developed as dual-level reactive oxygen species (ROS) amplifier for enhanced photothermal-chemodynamic therapy. The PoPD@CuS nanoplatform exhibited photothermal performance, chemodynamic performance, and GSH-depleting capability. Alongside its improved photothermal conversion efficiency with tumor pH-responsiveness, the photothermal behavior of PoPD@CuS could elevate chemodynamic activity by regulating the temperature spatiotemporally, leading to increased ROS production. Moreover, GSH depletion of PoPD@CuS could suppress ROS scavenging, further enhancing oxidative stress in the tumor region. Consequently, functioning as a dual-level ROS amplifier, PoPD@CuS showcased remarkable effectiveness in photothermal-chemodynamic combination therapy.

Schnurri-3 inhibition rescues skeletal fragility and vascular skeletal stem cell niche pathology in the OIM model of osteogenesis imperfecta.

Osteogenesis imperfecta (OI) is a disorder of low bone mass and increased fracture risk due to a range of genetic variants that prominently include mutations in genes encoding type I collagen. While it is well known that OI reflects defects in the activity of bone-forming osteoblasts, it is currently unclear whether OI also reflects defects in the many other cell types comprising bone, including defects in skeletal vascular endothelium or the skeletal stem cell populations that give rise to osteoblasts and whether correcting these broader defects could have therapeutic utility. Here, we find that numbers of skeletal stem cells (SSCs) and skeletal arterial endothelial cells (AECs) are augmented in Col1a2oim/oim mice, a well-studied animal model of moderate to severe OI, suggesting that disruption of a vascular SSC niche is a feature of OI pathogenesis. Moreover, crossing Col1a2oim/oim mice to mice lacking a negative regulator of skeletal angiogenesis and bone formation, Schnurri 3 (SHN3), not only corrected the SSC and AEC phenotypes but moreover robustly corrected the bone mass and spontaneous fracture phenotypes. As this finding suggested a strong therapeutic utility of SHN3 inhibition for the treatment of OI, a bone-targeting AAV was used to mediate Shn3 knockdown, rescuing the Col1a2oim/oim phenotype and providing therapeutic proof-of-concept for targeting SHN3 for the treatment of OI. Overall, this work both provides proof-of-concept for inhibition of the SHN3 pathway and more broadly addressing defects in the stem/osteoprogenitor niche as is a strategy to treat OI.

Comparison of Mitral Valve Repair Versus Percutaneous Mitral Balloon Commissurotomy for Patients With Rheumatic Heart Disease: A Single-Centre Study.

BACKGROUND: Percutaneous mitral balloon commissurotomy (PMBC) is the standard treatment option for patients with rheumatic mitral stenosis (MS), according to current guidelines. This study aimed to compare the outcomes of rheumatic mitral valve repair (rMVR) and PMBC in this patient population. METHODS: Baseline, clinical, and follow-up data from 703 patients with rheumatic heart disease who underwent PMBC or rMVR at the current centre were collected and analysed. A 1:1 propensity score (PS) matching method was used to balance the differences in baseline characteristics between the two groups. The primary outcome was mitral valve reoperation, and the secondary outcome was all-cause mortality. RESULTS: Propensity score matching generated 101 patient pairs for comparison. In the matched population, there were no significant differences in the early clinical outcomes between the groups. The median follow-up time was 40.9 months. Overall, patients in the rMVR group had a statistically significantly lower risk of mitral valve reoperation than those in the PMBC group (HR 0.186; 95% CI 0.041-0.835; p=0.028). Regarding all-cause mortality, no statistically significant differences were observed between the rMVR and PMBC groups (HR 4.065; 95% CI 0.454-36.374; p=0.210). CONCLUSIONS: Compared with PMBC, rMVR has more advantages for the correction of valve lesions; therefore, it may offer a better prognosis than PMBC in select patients with rheumatic MS. However, this finding needs to be verified in future studies with larger sample sizes and longer follow-up periods.

Enantioselective Aminosilylation of Alkenes by Palladium/Ming-Phos-Catalyzed Tandem Narasaka-Heck/Silylation Reaction.

A Pd-catalyzed enantioselective aminosilylation of alkenes via tandem Aza-Heck/silylation reaction under Pd/Sadphos catalysis is disclosed. A wide array of oxime esters and silicon reagents are tolerated, furnishing the chiral pyrrolines bearing one quaternary or two contiguous stereocenters in good yield with high enantioselectivity. Not only terminal alkenes but also tri-substituented internal alkenes successfully participate in the reaction, delivering vicinal stereocenters in complete diastereoselectivity and high enantioselectivity. DFT study is conducted to probe the reaction pathway and the origin of the enantioselectivity, which revealed that the stereoinduction arises from the weak interaction between the aromatic ring of the substrate fragment and naphthyl group in the ligand.

Association of Helicobacter pylori infection with colorectal polyps/adenomas: A single-center cross-sectional study.

BACKGROUND: Helicobacter pylori (H. pylori) infection may be associated with colorectal polyps/adenomas, but the current evidence remains controversial. METHODS: We retrospectively screened the medical records of 655 participants who underwent both colonoscopy and H. pylori test from June 15, 2020 to April 30, 2023. The number, size, location, and pathological type of colorectal polyps/adenomas were compared between H. pylori positive and negative groups. Adjusting for age, gender, smoking, drinking, hypertension, diabetes, fatty liver, body mass index, and inflammatory and metabolic indicators, multivariate logistic regression analyses were performed to evaluate the association of H. pylori infection with the number, size, location, and pathological type of colorectal polyps/adenomas, where no polyp/adenoma was used as reference. RESULTS: Overall, 508 participants were included, of whom 154 and 354 were divided into H. pylori positive and negative groups, respectively. H. pylori positive group had significantly higher colorectal polyps/adenomas (74.7 % vs. 65.8 %, P=0.048), low-grade adenomas (55.7 % vs. 47.6 %, P=0.026), advanced adenomas (22.6 % vs. 13.3 %, P=0.008), and colorectal polyps/adenomas with sizes of ≥6 mm (61.7 % vs. 48.5 %, P=0.002) and ≥10 mm (25.2 % vs. 14.6 %, P=0.004) than H. pylori negative group. In multivariate logistic regression analyses, H. pylori infection was independently associated with low-grade adenomas (OR=2.677, 95 %CI=1.283-5.587, P=0.009), advanced adenomas (OR=3.017, 95 %CI=1.007-9.036, P=0.049), right-side colon polyps/adenomas (OR=5.553, 95 %CI=1.679-18.360, P=0.005), and colorectal polyps/adenomas with sizes of ≥10 mm (OR=4.436, 95 %CI=1.478-13.310, P=0.008), but not number of colorectal polyps/adenomas. CONCLUSION: H. pylori infection is associated with increased risk of colorectal polyps/adenomas, especially low-grade adenomas, advanced adenomas, right-side colon polyps/adenomas, and large colorectal polyps/adenomas.

AC-ModNet: Molecular Reverse Design Network Based on Attribute Classification.

Deep generative models are becoming a tool of choice for exploring the molecular space. One important application area of deep generative models is the reverse design of drug compounds for given attributes (solubility, ease of synthesis, etc.). Although there are many generative models, these models cannot generate specific intervals of attributes. This paper proposes a AC-ModNet model that effectively combines VAE with AC-GAN to generate molecular structures in specific attribute intervals. The AC-ModNet is trained and evaluated using the open 250K ZINC dataset. In comparison with related models, our method performs best in the FCD and Frag model evaluation indicators. Moreover, we prove the AC-ModNet created molecules have potential application value in drug design by comparing and analyzing them with medical records in the PubChem database. The results of this paper will provide a new method for machine learning drug reverse design.

What enlightenment has the development of lung cancer bone metastasis brought in the last 22 years.

BACKGROUND: Lung cancer bone metastasis (LCBM) is a disease with a poor prognosis, high risk and large patient population. Although considerable scientific output has accumulated on LCBM, problems have emerged, such as confusing research structures. AIM: To organize the research frontiers and body of knowledge of the studies on LCBM from the last 22 years according to their basic research and translation, clinical treatment, and clinical diagnosis to provide a reference for the development of new LCBM clinical and basic research. METHODS: We used tools, including R, VOSviewer and CiteSpace software, to measure and visualize the keywords and other metrics of 1903 articles from the Web of Science Core Collection. We also performed enrichment and protein-protein interaction analyses of gene expression datasets from LCBM cases worldwide. RESULTS: Research on LCBM has received extensive attention from scholars worldwide over the last 20 years. Targeted therapies and immunotherapies have evolved into the mainstream basic and clinical research directions. The basic aspects of drug resistance mechanisms and parathyroid hormone-related protein may provide new ideas for mechanistic study and improvements in LCBM prognosis. The produced molecular map showed that ribosomes and focal adhesion are possible pathways that promote LCBM occurrence. CONCLUSION: Novel therapies for LCBM face animal testing and drug resistance issues. Future focus should centre on advancing clinical therapies and researching drug resistance mechanisms and ribosome-related pathways.

3D Porous Fibers with Spatial Traps and Excellent Zn2+ Transport Kinetics Enable Stable Zn-Based Aqueous Battery.

Adverse side reactions and uncontrolled Zn dendrites growth are the dominant factors that have restricted the application of Zn ion batteries. Herein, a 3D self-supporting porous carbon fibers (denoted as PCFs) host is developed with "trap" effect to adjust the Zn deposition. The unique open structural design of N-doped carbon can act as the zincophilic sites to induce uniform deposition and inhibit adverse side reactions. More importantly, the porous hollow PCFs host with "trap" effect can induce Zn deposition in the fiber by adjusting the local electric field and current density, thereby increasing the specific energy density of the battery and inhibiting dendrite growth. In addition, the 3D open frameworks can regulate Zn2+ flux to enable outstanding cycling performance at ultra-high current densities. As expected, the PCFs framework guarantees the uniform Zn plating and stripping with an outstanding stability over 6000 cycles at the current density of 40 mA cm-2. And the Zn@PCFs||MnO2 full battery shows an excellent lifespan over 1300 cycles at 2000 mA g-1.
