Network pharmacology and molecular docking reveal the mechanism of resveratrol in oral squamous cell carcinoma treatment / 口腔疾病防治

Objective@#To explore the molecular mechanism of resveratrol (RES) in the treatment of oral squamous cell carcinoma (OSCC) through the use of biological information methods such as network pharmacology and molecular docking and to provide a theoretical reference for the clinical application of RES in the treatment of OSCC.@*Methods@#The Swiss Target Prediction(http://www.swisstargetprediction.ch), SEA (http://sea.bkslab.org)database, and Pharm mapper database(http://lilab-ecust.cn) were used to retrieve RES-related targets, and the DISGENET (www.disgenet.org), OMIM (https://omim.org) and GeneCards (https://www.genecards.org) databases were used to screen OSCC disease targets. The intersection of drugs and disease targets was determined, and Cytoscape 3.7.2 software was used to construct a "drug-diseasetarget pathway" network. The Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) database was used to construct a target protein interaction network, and the DAVID database was used for enrichment analysis of key proteins. Finally, molecular docking validation of key proteins was performed using AutoDock and PyMOL. The enrichment analysis and molecular docking results were integrated to predict the possible molecular mechanisms of RES treatment in OSCC; western blot was used to determine the effect of resveratrol at different concentrations (50, 100) μmol/L on the expression of Src tyrosine kinase (SRC), epidermal growth factor receptor (EGFR), estrogen receptor gene 1 (ESR1), and phosphatidylinositol 3 kinase/protein kinase B (PI3K/AKT) signaling pathway proteins in OSCC HSC-3 cells.@*Results@#A total of 243 targets of RES drugs and 6 094 targets of OSCC were identified. A total of 116 potential common targets were obtained by intersecting drugs with disease targets. These potential targets mainly participate in biological processes such as in vivo protein self-phosphorylation, peptide tyrosine phosphorylation, transmembrane receptor protein tyrosine kinase signaling pathway, and positive regulation of RNA polymerase Ⅱ promoter transcription, and they interfere with the PI3K/AKT signaling pathway to exert anti-OSCC effects. The docking results of resveratrol with OSCC molecules indicated that key targets, such as EGFR, ESR1, and SRC, have good binding activity. The results of cell-based experiments showed that resveratrol inhibited the protein expression of SRC, EGFR, ESR1, p-PI3K, and p-AKT in HSC-3 cells in a dose-dependent manner.@*Conclusion@#RES can inhibit the expression of its targets EGFR, ESR1, SRC, p-PI3K, and p-AKT in OSCC cells.

Zoster sine herpete después de infección leve por SARS-CoV-2 / Zoster sine herpete after mild SARS-CoV-2 infection

El SARS-CoV-2 es un virus de afectación sistémica que impacta con gran intensidad en el sistema inmunológico; esto permite que virus de naturaleza latente, como el virus de Varicela Zoster (VVZ), tengan oportunidad de reactivarse y agravar el cuadro respiratorio con afectaciones cutáneas, mucosas y neurológicas. Se presenta un caso de Zoster sine herpete, durante la convalecencia del SARS-CoV-2, en un paciente masculino de 43 años, que acudió a consulta por dolor precordial de gran intensidad, sensación de escozor en tórax posterior y dificultad respiratoria; 10 días después de prueba de hisopado nasofaríngeo positiva para antígeno de SARS-CoV-2. Es importante no olvidar la probabilidad de presentaciones atípicas de virus latentes con el fin de realizar un diagnóstico y tratamiento oportuno a los pacientes.

SARS-CoV-2 is a systemic virus that has a strong impact on the immune system; this allows latent viruses, such as varicella-zoster virus (VZV), to reactivate and aggravate the respiratory symptoms with cutaneous, mucosal and neurological involvement. We present a case of Zoster sine herpete, during convalescence from SARS-CoV-2, in a 43-year-old male patient who presented with severe precordial pain, stinging sensation in the posterior thorax and respiratory distress; 10 days after a positive nasopharyngeal swab test for SARS-CoV-2 antigen. It is important not to forget the probability of atypical presentations of latent viruses to make a timely diagnosis and treatment of patients.

Six1 gene methylation status in gastric cancer and relationship with clinicopathological characteristics and prognosis / 中国医师进修杂志

Objective:To detect the methylation status of sine oculis homeobox homolog1 (Six1) in patients with gastric cancer and analyze its relationship with the clinicopathological characteristics and prognosis of patients.Methods:The tumor and para-cancerous tissues of 148 patients with gastric cancer diagnosed and treated in Aerospace Center Hospital from September 2015 to December 2017 were collected. The methylation-specific PCR method (MSP) was used to detect the methylation status of the Six1 gene, and 100 normal people who underwent gastroscopy biopsy during the same period served as the control group. Univariate analysis and multivariate Logistic regression model were used to analyze the relationship between Six1 methylation status and clinical pathological characteristics of patients. Kaplan-Meier survival curve was used to analyze the relationship between Six1 methylation status and prognostic survival in patients with gastric cancer.Results:Six1 gene methylation rate in tumor tissue was lower than that in adjacent tissues or in control group, and the differences were statistically significant: 24.32%(36/148) vs. 89.19%(132/148), 96.00%(96/100)( P<0.05). Univariate analysis showed that Six1 gene methylation rate was higher in patients with tumor diameter <5 cm ( χ2 = 8.79, P = 0.003), TNM stage Ⅰ-Ⅱ ( χ2 = 4.93, P = 0.026), highly differentiated tumor ( χ2 = 8.74, P = 0.013), no lymph node metastasis ( χ2 = 4.64, P = 0.031), no distant metastasis ( χ2 = 4.38, P = 0.036), and no invasion of the serosa ( χ2 = 9.85, P = 0.002), and the differences were statistically significant. Multivariate analysis showed that TNM staging ( OR = 4.397, 95% CI 3.141 - 5.157, P = 0.014), tumor differentiation ( OR = 4.491, 95% CI 3.527 - 6.118, P = 0.007), lymph node metastasis ( OR = 4.208, 95% CI 3.823 - 5.195, P = 0.031), distant metastasis ( OR = 4.225, 95% CI 3.956 - 5.437, P = 0.026), and depth of invasion ( OR = 4.509, 95% CI 3.206 - 5.275, P = 0.011) of patients with gastric cancer were independent risk factors for Six1 gene methylation status. Till to March 2020, the mortality rate of the Six1 gene methylation group was lower than that of the Six1 gene unmethylated group: 44.44%(16/36) vs.71.43% (80/112), the difference was statistically significant ( χ2 = 8.70, P<0.05). The median survival time of gastric cancer patients with Six1 gene methylation was higher than that of Six1 gene unmethylated (49 months vs. 37 months), and the difference was statistically significant ( P = 0.019). Conclusions:There is unmethylation of Six1 gene in patients with gastric cancer, which may be involved with the occurrence of gastric cancer. Patients′ TNM stage, tumor differentiation degree, and lymph node metastasis are independent risk factors for Six1 gene methylation status in gastric cancer patients. The prognosis of gastric cancer patients with Six1 gene methylation is better.

Heart sound classification based on improved mel frequency cepstrum coefficient and integrated decision network method / 生物医学工程学杂志

Heart sound analysis is significant for early diagnosis of congenital heart disease. A novel method of heart sound classification was proposed in this paper, in which the traditional mel frequency cepstral coefficient (MFCC) method was improved by using the Fisher discriminant half raised-sine function (F-HRSF) and an integrated decision network was used as classifier. It does not rely on segmentation of the cardiac cycle. Firstly, the heart sound signals were framed and windowed. Then, the features of heart sounds were extracted by using improved MFCC, in which the F-HRSF was used to weight sub-band components of MFCC according to the Fisher discriminant ratio of each sub-band component and the raised half sine function. Three classification networks, convolutional neural network (CNN), long and short-term memory network (LSTM), and gated recurrent unit (GRU) were combined as integrated decision network. Finally, the two-category classification results were obtained through the majority voting algorithm. An accuracy of 92.15%, sensitivity of 91.43%, specificity of 92.83%, corrected accuracy of 92.01%, and F score of 92.13% were achieved using the novel signal processing techniques. It shows that the algorithm has great potential in early diagnosis of congenital heart disease.

Novel compound heterozygous mutations in the PCDH15 gene in a family affected with Usher syndrome type 1F with retinitis pigmentosa sine pigmento / 中华眼底病杂志

Objective:To identify the causative gene in a family affected with Usher syndrome (USH) with retinitis pigmentosa sine pigmento (RPSP) and to analyze the genotype-phenotype correlation.Methods:A retrospective clinical study. A 9-year-old girl with RPSP type 1F USH diagnosed in the ophthalmology clinic of Henan Provincial People's Hospital in November 2019 and her parents were included in the study. The patient had bilateral night blindness for more than 4 years, she suffered from hearing loss 7 years, and is currently binaural sensorineural deafness. The best corrected visual acuity in both eyes was 0.5 +. There was showed no obvious pigmentation on the fundus. The visual acuity of the peripheral field of vision decreased. Optical coherence tomography showed that the outer layer of the peripheral retina became thinner and the ellipsoid band disappeared. On electroretinogram examination, the rod and cone system response was severely decreased. The clinical phenotype of the parents of the child were normal. The peripheral venous blood of the child and his parents were extracted, the whole genome DNA was extracted, the custom developed targeted capture kit (PS400) was used, and the next-generation sequencing technology was used to detect genetic mutations. The suspected pathogenic mutation sites were verified by Sanger; co-segregation was performed among family members. The pathogenicity of variants were evaluated according to the interpretation standards and guidelines of sequence variants. Bioinformatics techniques were used to assess the impact of variants on encoded proteins. Results:The results of genetic testing showed that the proband detected the PCDH15 gene c.4109dupA (p.K1370fs) (M1), c.17dupA (p.Y6_L7delinsX) (M2) compound heterozygous mutation sites, verified by Sanger sequencing, the mutations were in the family in a state of co-segregation. According to the evaluation of sequence variation interpretation standards and guidelines, M1 and M2 were pathogenic variants of the PCDH15 gene. M1 led to a complete change in the transmembrane structure of the encoded protein, and M2 caused the gene to only translate 6 amino acids, which predicted that the PCDH15 protein cannot be synthesized. According to the clinical phenotype, gene mutation pathogenicity and protein structure prediction, the final clinical diagnosis was PCDH15-related type 1F. Conclusions:PCDH15 genes c.4109dupA and c.17dupA are the pathogenic mutation sites of USH in this family. These compound heterozygous new mutations lead to the failure of normal synthesis of PCDH15 protein, which leads to ocular and ear manifestations.

SIX1 Promotes Proliferation and Invasion of Breast Cancer Cells / 中国生物化学与分子生物学报

Sine oculis homeobox homolog 1 (SIX1) is involved in the regulation of many kinds of tumors and plays an important role in the occurrence and development of breast cancer, but the exact mechanism remains to be explored. In this study, we analyzed the expression of SIX1 in breast cancer, and investigated the role of SIX1 in the proliferation and invasion of breast cancer cells. TCGA database and GEPIA2 showed that the expression of SIX1 in breast cancer was significantly higher than that in normal tissues, which was confirmed in different molecular subtypes of breast cancer, including Basal-like, HER2, Luminal A and Luminal B (P < 0. 05). Besides, the analysis of HPA database also showed that the expression of SIX1 was significantly upregulated in breast cancer, and the difference was statistically significant (P < 0. 001). After interfering with the expression of SIX1 in the breast cancer cell line MDA-MB-231 and overexpressing SIX1 in MCF-7, the growth curve and EdU results showed that the proliferation of breast cancer cells was inhibited after knocking down SIX1, while overexpression of SIX1 could promote the proliferation ability (the growth curve assays: P < 0. 05; EdU assays: P < 0. 001). Besides, Transwell assays showed that SIX1 could enhance the invasion ability of breast cancer cells (P < 0. 001). In TCGA database we defined the high and low expression populations according to the upper and lower quartiles of SIX1 gene expression, and differentially expressed genes were found to be associated with metabolism and stem cell regulatory pathways. For further confirmation, high-throughput RNA deep sequencing (RNA-seq) was conducted using SIX1-knockdown cells, and analysis also showed that SIX1 was closely related to metabolism, stem cell regulation and EMT pathways. We selected several representative genes, MYC, SNAI2 and EGFR, to examine their associations with SIX1 expression and prognosis in patients with clinical breast cancer using published GEO datasets and KM-plotter, we found that SIX1 was positively correlated with the expression of MYC, SNAI2 and EGFR, and the high expression of SIX1, MYC, SNAI2 and EGFR is not conducive to the survival of breast cancer patients. GCBI, GeneMANIA and String online tools were conducted to predict the associated genes, lncRNA and miRNA of SIX1. Collectively, our study initially revealed the role of SIX1 in breast cancer and its regulatory mechanism, providing new insights for further studies.

Descending Aortic Rupture after Frozen Elephant Trunk Technique for Dissected Aortic Arch Aneurysm / 日本心臓血管外科学会雑誌

We report a 41-year-old man who presented with a ruptured dissecting aneurysm of the descending aorta. He had undergone aortic root replacement for an acute aortic dissection (Stanford type A) ; 8 months later, he had undergone total arch replacement with insertion of a frozen elephant trunk (FET) due to enlargement of the chronic dissecting aneurysm of the arch. FET-induced new entry and incomplete thrombosis occurred postoperatively. Three months after FET insertion, he developed an aortic rupture that required emergency replacement of the descending aorta. The patient tolerated the procedure well and was discharged 16 days after the operation.

Protein mass spectrometry extends temporal blood meal detection over polymerase chain reaction in mouse-fed Chagas disease vectors

BACKGROUND Chagas disease is highly prevalent in Latin America, and vector control is the most effective control strategy to date. We have previously shown that liquid chromatography tandem mass spectrometry (LC-MS/MS) is a valuable tool for identifying triatomine vector blood meals. OBJECTIVES The purpose of this study was to determine blood meal detection ability as a function of method [polymerase chain reaction (PCR) vs. LC-MS/MS], time since feeding, and the effect of molting in mouse-fed triatomine insect vectors targeting hemoglobin and albumin proteins with LC-MS/MS and short interspersed nuclear elements (SINE)-based PCR. METHODS We experimentally fed Triatoma protracta on mice and used LC-MS/MS to detect hemoglobin and albumin peptides over time post-feeding and post-molting (≤ 12 weeks). We compared LC-MS/MS results with those of a standard PCR method based on SINEs. FINDINGS Hemoglobin-based LC-MS/MS detected blood meals most robustly at all time points post-feeding. Post-molting, no blood meals were detected with PCR, whereas LC-MS/MS detected mouse hemoglobin and albumin up to 12 weeks. MAIN CONCLUSIONS In our study, the hemoglobin signature in the insect abdomen lasted longer than that of albumin and DNA. LC-MS/MS using hemoglobin shows promise for identifying triatomine blood meals over long temporal scales and even post-molting. Clarifying the frequency of blood-feeding on different hosts can foster our understanding of vector behavior and may help devise sounder disease-control strategies, including Ecohealth (community based ecosystem management) approaches.

Esclerosis sistémica sin esclerodermia, un desafío diagnóstico para el clínico: caso clínico y revisión de la literatura / Systemic sclerosis sine scleroderma: a clinical diagnostic challenge: clinical case and literature review

La Esclerodermia es una patología poco frecuente que afecta principalmente la piel, de ahí su nombre. Desde ese punto de vista existen diferentes clasificaciones siendo las más frecuentes: forma Difusa y Limitada. Existe también otra forma de presenta-ción, muy infrecuente y difícil de identificar: la esclerosis sistémica sin esclerodermia (eSSe). En este reporte presentamos el caso de una paciente de 50 años, que cursa con injuria renal aguda de origen inexplicado con algunos elementos de laboratorio de microangiopatía trombótica, sin clínica sugerente de esclerosis sistémica progre-siva y con laboratorio inicial difícil, lo que retrasó el diagnóstico y por ende el trata-miento. En este caso se obtiene el diagnóstico de crisis renal esclerodérmica, por los hallazgos compatibles de microangiopatía trombótica arrojados por la biopsia renal.

Systemic sclerosis is a rare connective tissue disease that is characterized by thickening of the skin (scleroderma). The disease has 2 main presentations forms: diffuse and limited. However, it can also manifest without scleroderma, known as systemic sclerosis sine scleroderma (ssSSc). In this report, we describe the case of a 50 years female who debut with acute renal injury and possible microangiopathy thrombotic elements in laboratory findings, in absence of signs of scleroderma at physical examination or initial laboratory test results, causing the delay of accurate diagnosis and management. Renal biopsy findings were compatible with thrombotic microangiopathy and renal sclerodermic crisis, which guided the diagnosis and subsequent management.

Dermatomyositis sine dermatitis, a rare phenotype of idiopathic inflammatory myopathy / 영남의대학술지

Dermatomyositis (DM) is characterized by progressive proximal limb weakness and typical skin manifestations. The histological findings that show perifascicular atrophy and deposition of membrane attack complex are pathognomic features of DM. Dermatomyositis is categorized into classical DM and non-classical DM, which includes amyopathic DM and DM sine dermatitis. DM sine dermatitis is seldom described because of its rarity, making the diagnosis more challenging. We report a case of DM sine dermatitis, a rare phenotype of DM.

Anti-inflammatory mechanism of low dose methotrexate and its application in spinal cord injury / 中国药理学通报

Methotrexate (MTX)has dual effects of anti-inflam-matory and immune suppression,and its pharmacological mecha-nism is complex,diverse and synergistic.This paper summari-zes the main anti-inflammatory mechanism of low-dose MTX,in-cluding inhibition of JAK/STAT pathway,inhibition of inflam-matory reaction and immune response,increasing the accumula-tion of adenosine and the function of intracellular metabolites (methotrexate polyglutamate).In addition,low-dose MTX can inhibit oxidation by decreasing the level of lipid peroxidation, suppress the inflammatory response to secondary spinal cord in-jury,reduce spinal cord ischemia reperfusion injury and neuro-pathic pain,thus playing a neuroprotective role by a series of pharmacological mechanism.The anti-inflammatory mechanism of low-dose MTX and its application in spinal cord injury were reviewed,to guide the further research on the anti-inflammatory effect of MTX,and provide a theoretical basis for new drugs for clinical treatment of spinal cord injury.

Diverse clinical manifestations caused by varicella-zoster virus reactivation / 영남의대학술지

The two distinctive clinical features of varicella-zoster virus (VZV) are varicella (chickenpox) by primary infection and zoster (singles) by the reactivation of latent infection. In addition to the two typical clinical symptoms mentioned above, diverse clinical manifestations have been reported as a result of VZV reactivation, including chronic radicular pain without rash, visual loss, facial palsy, dysphagia, sore throat, odynophagia, otalgia, hearing loss, dizziness, headache, hemiplegia, etc. Most of these symptoms are derived from neuropathy and vasculopathy of affected nerves and arteries. Diagnosis of VZV disease can be difficult if there is no appearance of a skin rash during development of atypical symptoms. In addition to natural infection, vaccination and anti-viral agent treatment have influenced the changes of epidemics and clinical presentations of varicella and zoster. In this article, diverse clinical manifestations caused by VZV reactivation, particular without skin rash, are reviewed.

Parálisis Parcial del Nervio Oculomotor Secundaria a Zoster Sine Herpete: Reporte de Un Caso / Partial Palsy of the Oculomotor Nerve Due to Zoster Sine Herpete: A Case Report

Introducción: Herpes Zoster es la reactivación del Virus Varicela Zóster en los ganglios sensoriales y/o autonómicos, típicamente caracterizado por dolor profundo de distribución dermatómica y erupciones vesiculares en piel. De manera infrecuente, puede presentarse el Zoster Sine Herpete, condición en la cual se presenta la distribución dermatómica del dolor en ausencia de lesiones dérmicas, convirtiendo el diagnóstico en un reto clínico. Caso clínico: Hombre de 69 años con dolor periorbitario, epifora, ptosis y pérdida de la aducción del ojo derecho. Los estudios imagenológicos y de laboratorio fueron normales, descartando así las principales causas de parálisis del nervio oculomotor. Se hizo diagnóstico presuntivo de Zoster Sine Herpete y se inició prueba terapéutica con valaciclovir, observándose resolución total de la sintomatología seis semanas después. Discusión: Este caso puede ser el primero en describir una parálisis parcial dolorosa del nervio oculomotor como única manifestación clínica de la reactivación del Virus Varicela Zóster y busca alertar al personal médico sobre una enfermedad latente que hace de sus reapariciones una gama de presentaciones no siempre fáciles de identificar.

Introduction: Herpes zoster is the reactivation of the varicella zoster virus in the sensorial and/ or autonomic ganglia, typically characterized by cutaneous vesicular eruptions and deep pain with dermatomal distribution. Infrequently can occur the Zoster Sine Herpete; condition in which there is dermatomal distribution of the pain in absence of dermic injuries, making the diagnosis a challenge for the clinician. Case report: 69 years old man with periorbital pain, epiphora, ptosis and loss of adduction of the right eye. The imaging and laboratory studies were normal, excluding with this the main causes of oculomotor nerve palsy. A presumptive diagnosis of Zoster Sine Herpete was done and a therapeutic test with valacyclovir was initiated, showing complete resolution 6 weeks later without sequelaes. Discussion: This case may be the first in describing partial painful oculomotor nerve palsy as the only manifestation of the varicella zoster virus reactivation and seeks to aware the medical staff about a latent disease that makes from his reappearances a wide range of presentations not always easily to identify.

Familial aggregation of cluster headache / Agregacao familiar da cefaleia em salvas

Several studies suggest a strong familial aggregation for cluster headache (CH), but so far none of them have included subjects with probable cluster headache (PCH) in accordance with the International Classification of Headache Disorders. Objective To identify cases of probable cluster headache and to assess the familial aggregation of cluster headache by including these subjects. Method Thirty-six patients attending a headache consultation and diagnosed with trigeminal autonomic headaches were subjected to a questionnaire-based interview. A telephone interview was also applied to all the relatives who were pointed out as possibly affected as well as to some of the remaining relatives. Results Twenty-four probands fulfilled the criteria for CH or PCH; they had 142 first-degree relatives, of whom five were found to have CH or PCH, including one case of CH sine headache. The risk for first-degree relatives was observed to be increased by 35- to 46-fold. Conclusion Our results suggest a familial aggregation of cluster headache in the Portuguese population. .

Spinal Arteriovenous Malformation Masquerating Zoster Sine Herpete

Zoster sine herpete (ZSH) is difficult to diagnosis during an acute period due to the absence of the characteristic zosteriform dermatomal rash; therefore, progression to postherpetic neuralgia is more common than typical zoster. In addition, misdiagnosis of other neuropathic pain as ZSH is common in clinical situations. Here, we report a case of spinal arteriovenous malformation that mimics ZSH. This is a rare condition; therefore, high clinical suspicion for a correct diagnosis and proper examination are not easy. However, early diagnosis and definitive treatment are essential to prevent neurologic deficit and mortality.
