RESUMEN
Head and neck squamous cell carcinoma(HNSCC)is the most common type of head and neck cancer,with poor prognosis and poor quality of life.In recent years,with the rapid development of targeted therapy,cetuximab has been widely used in clinical practice as the molecular targeted drug approved by the Food and Drug Administration(FDA)for the treatment of HNSCC.For locally advanced and recurrent/distant metastatic HNSCC,cetuximab combined with radiotherapy,chemotherapy,concurrent chemoradiotherapy,or combined radiotherapy after induction chemotherapy have shown great advantages.The treatment of HNSCC has now entered the era of immunity.Several clinical trials data have shown that cetuximab combined with immunotherapy or new targeted drugs have significant effects on HNSCC.In the future,scholars need to further explore immunotherapy to provide better choices for patients with HNSCC.This article reviews the mechanism of action of cetuximab and its research progress in the treatment of HNSCC.
RESUMEN
ObjectiveTo explore the role of saikosaponin D (SSD) targeting signal transducer and activator of transcription 3 (STAT3) in inducing apoptosis of bladder cancer cells by computer-aided drug design and experimental verification. MethodThe druggability and biotoxicity of SSD were explored by Bayesian classifier modeling. The information about SSD, the active ingredient of Bupleuri Radix, was searched against the Traditional Chinese Medicine Systematic Pharmacology Database and Analysis Platform (TCMSP). The targets of SSD were predicted by PubChem, TCMSP, a Bioinformatics Analysis Tool for Molecular mechANism of Traditional Chinese Medicine (BATMAN-TCM), Coremine, an Encyclopedia of Traditional Chinese Medicine (ETCM), and SwissTargetPrediction. GeneCards, Therapeutic Target Database (TTD), and Online Mendelian Inheritance in Man (OMIM) were employed to predict the potential therapeutic targets of bladder cancer. Then, the common targets shared by SSD and bladder cancer were selected for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Molecular docking was adopted to explore the binding affinity and structural stability of SSD with target proteins. Cytoscape 3.9.1 was used to construct the STAT3-drug regulatory network and STAT3-apoptosis regulatory network. UM-UC-3 cells were treated with 0, 5, 10, 15 μmol·L-1 SSD for 24 h. Then, flow cytometry was used to detect the apoptosis of bladder cancer cells, and Western blot was employed to determine the protein levels of B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), Bcl-2-associated death promoter (Bad), STAT3, and phosphorylation (p)-STAT3. ResultBayesian classifier modeling and molecular docking showed that SSD had low biotoxicity and bound well to the target protein STAT3 to form a stable protein-ligand complex. There were 282 common targets between bladder cancer and SSD, among which STAT3 was the most central target. The GO enrichment analysis showed that the potential core therapeutic targets involved 3 036 biological processes, 82 cellular components, and 171 molecular functions. The KEGG enrichment analysis showed that the potential core targets were mainly related to the C-type lectin receptor signaling pathway, Toll-like receptor signaling pathway, and cell apoptosis pathway. The STAT3-drug regulatory network and STAT3-apoptosis regulatory network showed that 29 drugs interacted with STAT3, and 27 apoptosis-related genes had a strong correlation with STAT3. Flow cytometry showed that the apoptosis rate increased with the increase in SSD concentration (P<0.05). Western blotting results showed that SSD down-regulated the protein levels of p-STAT3 and Bcl-2 and up-regulated the protein levels of Bax and Bad in a concentration-dependent manner (P<0.05). ConclusionSSD has good druggability and low biotoxicity. It may promote the apoptosis of bladder cancer cells by targeting STAT3.
RESUMEN
Drug-target interactions (DTIs) prediction is an important step in drug discovery. As traditional biological experiments or high-throughput screening are high cost and time-consuming, many deep learning models have been developed. Overfitting must be avoided when training deep learning models. We propose a simple framework, called OverfitDTI, for DTI prediction. In OverfitDTI, a deep neural network (DNN) model is overfit to sufficiently learn the features of the chemical space of drugs and the biological space of targets. The weights of trained DNN model form an implicit representation of the nonlinear relationship between drugs and targets. Performance of OverfitDTI on three public datasets showed that the overfit DNN models fit the nonlinear relationship with high accuracy. We identified fifteen compounds that interacted with TEK, a receptor tyrosine kinase contributing to vascular homeostasis, and the predicted AT9283 and dorsomorphin were experimentally demonstrated as inhibitors of TEK in human umbilical vein endothelial cells (HUVECs).
RESUMEN
Interactions between gut microbiome and host immune system are fundamental to maintaining the intestinal mucosal barrier and homeostasis. At the host-gut microbiome interface, cell wall-derived molecules from gut commensal bacteria have been reported to play a pivotal role in training and remodeling host immune responses. In this article, we review gut bacterial cell wall-derived molecules with characterized chemical structures, including peptidoglycan and lipid-related molecules that impact host health and disease processes via regulating innate and adaptive immunity. Also, we aim to discuss the structures, immune responses, and underlying mechanisms of these immunogenic molecules. Based on current advances, we propose cell wall-derived components as important sources of medicinal agents for the treatment of infection and immune diseases.

With the rapid development of aging around the world, the incidence and prevalence of age-related dementia have increased significantly, leading to a huge burden on patients, families and society. So far, there are no drugs that can completely reverse degeneration of the nervous system. The core pathological mechanisms of dementia are not clear, and the occurrence and progression of degenerative diseases in the nervous system appears to be only rely on the prevention through lifestyle interventions. Among lifestyle interventions, a large amount of laboratory evidence and a small amount of epidemiological evidence suggest that time restricted feeding have excellent effects on preventing the occurrence and progression of degenerative diseases in the nervous system. However, due to the lack of evidence in human population, the application of time restricted feeding lacks scientific basis. By synthesizing the existing evidence, this review discussed the pathway network of time restricted feeding that antagonizes the nervous system degradation, suggesting that future studies should focus on population evidence and the combined effects of multiple effect pathways.
RESUMEN
INTRODUCTION: Cutaneous squamous cell carcinoma (cSCC) is a global malignant tumor with a high degree of malignancy. Once metastasis occurs, it will lead to poor prognosis and even death. This study attempts to find out the central genes closely related to cSCC metastasis, so as to clarify the molecular regulatory mechanism of cSCC metastasis and open up new ideas for clinical treatment. METHODS: Firstly, cSCC data set GSE98767 was used to establish a tumor metastasis model via clustering analysis. The key module and hub genes associated with cSCC metastasis were analyzed by weighted gene co-expression analysis (WGCNA). Next, the prognostic functions of hub genes were identified by functional and pathway enrichment analysis, pan-cancer analysis, and receiver operating characteristic-area under the curve (ROC-AUC) validation. Finally, the key genes were verified by clinical sample detection and biological in vitro test. RESULTS: A total of 19 hub genes related to cSCC metastasis were identified. They were highly expressed in cSCC metastatic tissues and were mainly enriched in cellular material and energy metabolism pathways. Overall survival (OS) and disease-free survival (DFS) results from pan-cancer analysis showed that eight and six highly expressed genes, respectively, with PAPSS2 and SCG5 had highly reliable ROC-AUC validation values and were poor prognostic factors. Clinical and biological tests also confirmed the upregulation of PAPSS2 and SCG5 in cSCC. Deletion of PAPSS2 and SCG5 resulted in decreased viability, migration, and invasion of A-431 cells. CONCLUSION: PAPSS2 and SCG5 may be important factors for cSCC metastasis, and they are involved in the regulation of cSCC cell viability, migration, and invasion.

BACKGROUND: Pre-harvest sprouting (PHS) is a serious limiting factor for wheat (Triticum aestivum L.) grain yield and end-use quality. Identification of reliable molecular markers and PHS-resistant germplasms is vital to improve PHS resistance by molecular marker-assisted selection (MAS), but the effects of allelic variation and haplotypes in genes conferring PHS resistance in winter wheat cultivars are less understood. RESULTS: Resistance to PHS was tested in 326 commercial winter wheat cultivars for three consecutive growing seasons from 2018-2020. The effects of alleles and haplotypes of 10 genes associated with PHS resistance were determined for all cultivars and were validated by introgressing the PHS-resistance allele and haplotype into a susceptible wheat cultivar. High level of phenotypic variation in PHS resistance was observed in this set of cultivars and 8 of them were highly resistant to PHS with stable germination index (GI) of less than 25% in each individual year. Allelic effects of nine genes and TaMFT haplotype analysis demonstrated that the haplotype Hap1 with low-GI alleles at five positions had the best PHS resistance. This haplotype has the priority to use in improving PHS resistance because of its high effectiveness and rare present in the current commercial cultivars. Among 14 main allelic combinations (ACs) identified, the AC1 carrying the haplotype Hap1 and the TaSdr-B1a allele had better PHS resistance than the other classes. The introgression of Hap1 and TaSdr-B1a is able to significantly improve the PHS resistance in the susceptible cultivar Lunxuan 13. CONCLUSIONS: The effectiveness of alleles conferring PHS resistance in winter wheat cultivars was determined and the useful alleles and haplotypes were identified, providing valuable information for parental selection and MAS aiming at improving PHS-resistance in winter wheat. The identification of the PHS-resistant cultivars without known resistance alleles offers an opportunity to explore new PHS-resistant genes.

The rapid emergence and global dissemination of SARS-CoV-2 that causes COVID-19 continues to cause an unprecedented global health burden resulting in more than 4 million deaths in the 20 months since the virus was discovered. While multiple vaccine countermeasures have been approved for emergency use, additional treatments are still needed due to sluggish vaccine rollout and vaccine hesitancy. Immunoadjuvant compounds delivered intranasally can guide non-specific innate immune responses during the critical early stages of viral replication, reducing morbidity and mortality. N-dihydrogalactochitosan (GC) is a novel mucoadhesive immunostimulatory polymer of {beta}-0-4-linked N-acetylglucosamine that is solubilized by the conjugation of galactose glycans. We tested GC as a potential countermeasure for COVID-19. GC administered intranasally before and after SARS-CoV-2 exposure diminished morbidity and mortality in humanized ACE2 receptor expressing mice by up to 75% and reduced infectious virus levels in the upper airway and lungs. Our findings demonstrate a new application for soluble immunoadjuvants like GC for preventing severe disease associated with SARS-CoV-2. Single Sentence SummaryThe immunoadjuvant N-dihydrogalactochitosan diminishes SARS-CoV-2 disease in humanized ACE2 mice representing a new countermeasure against COVID-19.
RESUMEN
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific cellular immune response may prove to be essential for long-term immune protection against the novel coronavirus disease 2019 (COVID-19). To assess COVID-19-specific immunity in the population, we synthesized selected peptide pools of SARS-CoV-2 structural and functional proteins, including Spike (S), Membrane (M), Envelope (E), Nucleocapsid (N) and Protease (P) as target antigens. Survey of the T cell precursur frequencies in healthy individuals specific to these viral antigens demonstrated a diverse cellular immunity, including high, medium, low and no responders. This was further confirmed by in vitro induction of anti-SARS-CoV-2 T cell immune responses using dendritic cell (DC)/T cell coculture, which supported the corresponding T cell precursor frequencies in each of the individuals tested. In general, the combination of all five viral antigen pools induced the strongest cellular immune response, yet individual donors responded differently to different viral antigens. Importantly, in vitro restimulation of the T cells with the DC-peptides induced increased anti-viral immune responses in all individuals even in the no responders, suggesting that repeated antigen stimulation could elicit a broad protection in immune naive population. Our analysis recapitulates the critical role of cellular immunity in fighting COVID-19 and the importance of analyzing anti-SARS-CoV-2 T cell response in addition to antibody response in the population. ImportanceFacing the rapid evolving SARS-CoV-2 variants in the world, current emphasis on antibody-producing vaccines needs a quick revisit. The virus-specific cellular immunity may prove to be essential for long-term protection against COVID-19. This study designed a series of antigenic peptides encompassing the conserved and/or essential domains of Spike (S), Membrane (M), envelope (E), Nucleocapsid (N) and Protease (P) as targets to assess Covid-19-specific immunity in the population. The results demonstrated a diverse cellular immunity, including high, medium, low and no responders. This was verified by in vitro generation of anti-SARS-CoV-2 T-cells from these subjects. The study suggested that individuals responded differently to the different viral antigens, and importantly, repeated stimulation could produce virus specific T cells in all individuals, including the no responders. This study illustrates the needs for assessing anti-viral cellular immunity in addition to antibody response in the general population.
RESUMEN
Objective To evaluate biomechanical properties of the personalized titanium alloy short femoral prosthesis by finite element analysis. Methods Based on the validated femoral finite element model, the base of the femoral neck was simulated, and by inserting different short femoral prostheses, four total hip replacement (THR) models, namely, the SMF stem model (Model A), BE1 stem model (Model B), MINI stem model (Model C) and personalized stem model (Model D) were established, respectively. The same loads and constraints were applied to four groups of models, and the von Mises stress distribution and deformation were calculated and analyzed, so as to compare mechanical stability of each model. Results The deformation of all THR models was smaller than that of the femur model under physiological state. The deformation of Model B was close to that of Model C, and the deformation of Model A was close to that of Model D. The peak stress of Model C was higher than that of the other 3 models, reaching 9555 MPa. The overall stress trend was Model C > Model B > Model D> Model A > Model under physiological state. Conclusions The peak stress, stress distribution of personalized short femoral stem were similar to that of SMF stem, with reasonable stress distribution, small stress shielding of the proximal femur, minimum overall deformation and shear stress of the prosthesis, and its effectiveness and stability could meet the requirements of human biomechanics, which could provide references for joint surgeons and prosthesis researchers.

Objective:To explore an effective treatment method for mycobacterial infection of multiple abscesses in the face and breast after autologous fat injection.Methods:Six patients with non-tuberculous mycobacterial infection after autologous fat injection in the face and chest were treated from June to September in 2018. All patients underwent preoperative ultrasound localization. The small incision was opened for debridement and the necrotic granular tissues were completely scraped. Vacuum aspiration therapy in the sinus was used to promote wound growth, in line with the standard anti-tuberculosis drug treatment.Results:All six patients in this group were being followed up for 10-14 months. The average follow-up time was 12 months. All the infected patients were recovered, and the appearance of the infected site was satisfied by the patients.Conclusions:Small incision debridement with vacuum aspiration therapy combined with a variety of anti-tuberculosis drugs can effectively treat non-tuberculous mycobacterial infection after autologous fat injection, and achieve good results.
RESUMEN
In recent years, in the absence of venous component, dilated, overlapping, and tortuous arteries forming a mass of arterial loops with a coil-like appearance have been defined as pure arterial malformation (PAM). It is extremely rare, and its etiology and treatment have not yet been fully elucidated. Here, we reported 2 cases of PAM with associated aneurysmal subarachnoid hemorrhage in this paper. Both patients had severe headache as the first symptom. Subarachnoid hemorrhage was found by CT and computed tomography angiography (CTA) and PAM with associated aneurysm was found by digital subtraction angiography (DSA). In view of the distribution of blood and the location of aneurysms, the aneurysm rupture was the most likely to be considered. Based on the involvement of the lesion in the distal blood supply, only the aneurysm was clamped during the operation. It used to be consider that PAM is safety, because of the presentation and natural history of previously reported cases. Through the cases we reported, we have doubted about "the benign natural history" and discussed its treatment. PAM can promote the formation of aneurysms and should be reviewed regularly. The surgical indications for PAM patients with aneurysm formation need to be further clarified. Management of PAM patients with ruptured aneurysm is the same as that of ruptured aneurysm. Whether there are indications needed to treat simple arterial malformations remains to be further elucidated with the multicenter, randomized controlled studies on this disease.

Objective:To analyze the clinical manifestations and laboratory features of brucellosis patients in order to provide help for clinical diagnosis.Methods:The medical records of confirmed brucellosis patients ( n=81) in Kunming Third People's Hospital from 2015 to 2019 were collected. The occupation, contact history, clinical manifestations, laboratory examination characteristics and treatment of the patients were retrospectively analyzed. Results:The 81 cases of brucellosis were mainly farmers (64 cases), most of who had a history of raising sheep or contacting sheep manure or secretions (71 cases). The clinical manifestations were fever (68 cases), low back pain (42 cases), joint pain (22 cases), including 72 cases in acute stage and 9 cases in chronic stage. Laboratory examination showed that liver function index total bilirubin (TB) and direct bilirubin (DB) were generally normal, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma glutamyltransferase (GGT) were increased in about half of the patients; high sensitivity C-reactive protein (HsCRP), procalcitonin (PCT), interleukin-6 (IL-6) and serum amyloid A (SAA) were increased in more than 80% of the patients, and erythrocyte sedimentation rate (ESR) was increased in 64.6% (42/65) of the patients. Doxycycline plus rifampicin was the first-line treatment program.Conclusion:The clinical manifestations of patients with brucellosis are diverse and atypical, and patients with nonspecific clinical manifestations such as fever should be combined with their occupation, contact history, indicators of infection detection, timely blood culture examination to make a clear diagnosis, and patients with abnormal liver function should pay attention to asking about occupation and contact history, so as to reduce misdiagnosis and mistreatment of brucellosis.

Objective:To evaluate the efficacy and safety of adalimumab in the treatment of severe plaque psoriasis.Methods:From June 2018 to April 2019, 20 patients with severe plaque psoriasis were collected from Department of Dermatology, Henan Provincial People′s Hospital. After initial subcutaneous injection of adalimumab at a dose of 80 mg, these patients were subcutaneously injected with adalimumab at a dose of 40 mg at weeks 1, 3, 5, 7, 9 and 11. At weeks 4, 8 and 12, psoriasis area and severity index (PASI) was recorded, and changes in skin lesions were observed by reflectance confocal microscopy (RCM) . Adverse reactions were monitored during treatment.Results:At week 4, 12 patients achieved a 50% reduction in PASI (PASI50) ; at week 8, 14 achieved PASI75; at week 12, 20 patients achieved PASI75, of which 5 achieved PASI90 and 2 achieved PASI100. As RCM showed, the melanin content in the basal layer of skin lesions was lower compared with that of perilesional normal skin before treatment, gradually increased within 4 weeks, and nearly returned to normal at week 12. No infections, tumors or other related adverse reactions occurred in the 20 patients.Conclusion:Subcutaneous injection of adalimumab every other week is markedly effective in the treatment of severe psoriasis, with few related adverse reactions.
