First impressions of Telesurgery robotic-assisted radical prostatectomy using the Edge medical robotic platform

ABSTRACT Purpose: We reported, as a referral center in prostate cancer, our perspectives and experience performing Telesurgery using robotic surgery and 5G network. Material and methods: We described and illustrated the Telesurgery applications and outcomes to treat a patient with prostate cancer located 1300 kilometers away from the surgeon (Beijing-Harbin) in China. We used the Edge Medical Robot (MP1000) in November 2023 in a 71-year-old patient with Gleason 6 (ISUP 1) in 8 cores from 13, PSA of 14 ng/dL, and clinical stage cT2a. MRI described a PIRADS 5 nodule on the left peripheral zone at the base, and 20gr prostate. We described details about the connection between centers, perioperative outcomes, and our perspectives as a referral center in prostate cancer. Results: We had no delays, or problems with network connection between the centers. The procedure was performed in 60 minutes, with no intra- or postoperative complications. Estimated blood loss was 100 mL. The patient was ambulating soon after anesthesia recovery. Final pathology described a Gleason 6 (ISUP 1) involving the left base and left seminal vesicle, negative surgical margins, and no lymph node involvement (pT3bN0). The patient was continent soon after catheter removal (7 days). Conclusion: As technological progress introduced novel robotic platforms and high-speed networks, the concept of Telesurgery became a tangible reality while 5G technology solved latency and transmission concerns. However, with these advancements, ethical considerations and regulatory frameworks should underline the importance of transparency and patient safety with responsible innovation in the field.

Transcription Factor E2F7 Activates PKMYT1 to Partially Suppress Adriamycin Sensitivity in Gastric Cancer Through the MAPK Signaling Pathway

ABSTRACT Background: Adriamycin (ADM) resistance remains an obstacle to gastric cancer chemotherapy treatment. Objective: The objective of this study was to study the role and mechanism of transcription factor E2F7 in sensitivity to ADM chemotherapeutic agents in gastric cancer. Methods: Cell viability and cell sensitivity were assessed by CCK-8 and IC50 values of ADM were calculated. The impact of ADM on cellular proliferative capacity was assessed through colony formation assay. The binding relationship between E2F7 and PKMYT1 was then verified by dual luciferase assay and chromatin immunoprecipitation assay. ERK1/ERK2 and p-ERK1/p-ERK2 protein expression levels were detected by western blot. Results: In both gastric cancer tissue and ADM-resistant cells, a conspicuous upregulation of E2F7 and PKMYT1 was observed. Upregulated PKMYT1 was notably enriched in the MAPK signaling pathway. Enhanced levels of E2F7 were shown to not only drive gastric cancer cell proliferation but also engender a reduction in the sensitivity of these cells to ADM. Furthermore, PKMYT1 emerged as a downstream target of E2F7. Activation of E2F7 culminated in the transcriptional upregulation of PKMYT1, and silencing E2F7 reversed the inhibitory impact of PKMYT1 overexpression on ADM sensitivity in gastric cancer cells. Conclusion: E2F7/PKMYT1 axis might promote the proliferation and partially inhibit ADM sensitivity of gastric cancer cells by activating the MAPK pathway.

Study on the remineralization of demineralized enamel surfaces with glycine-guided carboxymethyl chitosan/amorphous calcium phosphate / 口腔疾病防治

Objective@#To explore effect on the remineralization of demineralized enamel surfaces with glycine-guided carboxymethyl chitosan (CMC)/amorphous calcium phosphate (ACP).@*Methods@# Remineralized solultion at different stages were prepared: ①reactive CMC/ACP (CMC/ACP nanoparticles treated with NaClO), ②reactive CMC/ACP+glycine; transmission electron microscopy was used to detect the morphology of the remineralized solution particles. Twenty teeth were randomly divided into two groups: group A and group B. Reactive CMC/ACP was applied to the enamel surface of group A and group B was treated with reactive CMC/ACP remineralization solution containing glycine. Scanning electron microscopy was used to detect the enamel surface morphology before and after remineralization, and nanoindentation was used to detect the mechanical strength (including nanoindentation depth, hardness and elastic modulus) of the enamel surface.@*Results@#Under a transmission electron microscope, the particles in the reactive CMC/ACP remineralization solution were smooth, and the increase in particle size was approximately 100-300 nm. After the addition of glycine, the particles in the reactive CMC/ACP remineralization solution particles showed a linear ordered arrangement, and microcrystals were formed in the solution 15 min later, with a crystal length of approximately 5-15 μm. Remineralization in group A was granular and heterogeneous. In group B, the crystal morphology of the demineralized enamel was homogeneous and ordered, similar to that of natural enamel. The nanoindentation depth of group B after remineralization was smaller than that of group A, and it was closest to that of natural enamel, there was no significant difference between group B and natural enamel in terms of the hardness and elastic modulus of the enamel surface after remineralization.@*Conclusion@# CMC/ACP nanoparticles treated with NaClO can rapidly and specifically form directional and ordered remineralization on the enamel surface of a model of glycine-guided rapid remineralization of enamel caries. The surface structure of remineralized enamel is similar to that of natural enamel in terms of nanoindentation depth, hardness and elastic modulus.

Long non-coding RNA DUXAP9 promotes the proliferation and metastasis of head and neck squamous cell carcinoma / 口腔疾病防治

Objective@#To investigate the role of long non-coding RNA double homeobox A pseudogene 9 (DUXAP9) in head and neck squamous cell carcinoma (HNSCC) and to evaluate the expression level, molecular function and mechanism of DUXAP9 in HNSCC cells.@*Methods@#Differential expression of lncRNAs between normal and tumor tissues in HNSCC tissues were screened using lncRNA microarray, the expression level of DUXAP9 in HNSCC tissues and its relationship with prognosis were analyzed in the TCGA database. The expression levels of DUXAP9 in HNSCC tissues and cell lines were detected using qRT-PCR. The function in HNSCC cells after DUXAP9 silencing was evaluated using the CCK-8 assay, wound healing assay, Transwell migration assay and subcutaneous xenograft assay in nude mice. Changes in the transcription and translation of epithelial-mesenchymal transition (EMT)-related proteins in head and neck squamous cell carcinoma cells after DUXAP9 silencing were detected using qRT-PCR and Western blot.@*Results@#lncRNA microarray results showed that, compared to adjacent normal tissues, DUXAP9 was abnormally upregulated in HNSCC tissues. Analysis from TCGA database showed that, compared to HNSCC patients with low DUXAP9 expression, HNSCC patients with high DUXAP9 expression had poorer survival. The relative expression of DUXAP9 in HNSCC tissues and 4 HNSCC cell lines increased compared to paired adjacent normal tissues as detected using qRT-PCR. Silencing DUXAP9 significantly inhibited the proliferation, migration and expression of EMT-related genes in HNSCC cells. The silencing of DUXAP9 significantly inhibited subcutaneous tumorigenesis of the HNSCC cell line CAL27 in nude mice.@* Conclusion@#Silencing DUXAP9 significantly inhibited the proliferation of HNSCC cells and subcutaneous xenografts in nude mice. DUXAP9 may mediate the migration of head and neck squamous cell carcinoma cells via the EMT pathway.

A comparative study of the morphology of suboccipital cavernous sinus using magnetic resonance imaging and cast specimens / Un estudio comparativo de la morfología del seno cavernoso suboccipital utilizando imágenes de resonancia magnética y muestras de yeso

SUMMARY: A comparative study of the morphology of suboccipital cavernous sinus (SCS) using MRI and cast specimens was performed. The present retrospective study analysed the craniocervical magnetic resonance venography (MRV) imaging data of 61 patients. Three-dimensional reconstruction was performed using Mimics 19.0. The SCS left-right diameter(d1), distance from the midline (d2), supero-inferior diameter(d3), anteroposterior diameter (d4), distance from posterior diameter to skin (d5), and diameter of the SCS at different parts (d6-d8) were measured. Comparison between MRV images and cast specimens, the SCS, marginal sinus, anterior condylar vein, and vertebral artery venous plexus were symmetrical and could be bilaterally displayed, whereas the presence of extra condylar vein and posterior condylar vein exhibited different types. The adjacency between the SCS and its communicating vessels and changes in its communicating vessels corresponded well with the MRV images and cast specimens. Many types of the presence of left and right lateral condylar and posterior condylar veins were found in the cast specimens, which could be divided into the bilateral presence of posterior condylar and lateral condylar veins, unilateral presence of posterior condylar veins, and unilateral presence of lateral condylar vein. A total of 61 cases analysed using MRV images revealed the bilateral presence of posterior condylar and lateral condylar veins (77.1 %), the unilateral presence of posterior condylar vein (18.0 %), and the unilateral presence of lateral condylar vein (9.8 %), of which the bilateral presence of posterior condylar and lateral condylar veins accounted for the largest proportion. MRV images and cast specimens of the SCS showed its normal morphological structure and adjacency, thus providing accurate and complete Three-dimensional imaging anatomical data of the SCS and its communicating vascular structures. This study enriches the Chinese SCS imaging anatomy data and may be valuable in clinical practice.

Epidemiological and etiological characteristics of hand, foot and mouth disease among children aged 5 years and younger in Ningbo (2016 to 2019) / 北京大学学报(医学版)

OBJECTIVE@#To describe the epidemiological and etiological characteristics of hand, foot and mouth disease (HFMD) among children aged 5 years and younger in Ningbo after the access of entero-virus-A71 vaccine (2016 to 2019).@*METHODS@#A retrospective cohort study were performed in children aged 5 years and younger in Ningbo from 2016 to 2019. Data for incidence of HFMD was collected from the National Notifiable Disease Surveillance Reporting System and the Electronic Medical Records (EMRs) System, while the demographic information was derived from the Immunization Information System. Speci-mens were detected by real-time fluorescence quantitative PCR and the Wilson method was used to estimate the incidence rate and 95% confidence interval.@*RESULTS@#From 2016 to 2019, a total of 1 044 800 residential children were observed in this population-based cohort. In the study, 102 471 cases of HFMD were diagnosed in 2 651 081 person-years, revealing an overall incidence density of 3 865.25/100 000 person-years. There was no significant decline in the number of the cases after the vaccine was available. The number of the patients of hand foot mouth disease during the four years was 93 421, of whom 84 875 (90.85%) had only one incident record, while 8 946 (9.15%) had 2 or more cases in this period; there were 69 771 (66.06%) patients who only needed to see a doctor once for each disease, 19.92% of the patients needed to be treated twice, and 14 801 (14.02%) patients needed to go to the hospital or clinic three times or more. The incidence of HFMD showed obvious seasonality and periodicity, which mainly concentrated in April to July each year, and the epidemic cycle was 2 years; most of the cases were 1 to 3-year old children, with more cases in male. The incidence density varied across the region, with the highest density observed in Ninghai (4 524.76/100 000 person-years), followed by Xiangshan (3 984.22/100 000 person-years). In 3 748 library-conformed cases, 2 834(75.61%) were detected positive, among which enterovirus-A71, Cox-A16 and other enteroviruses accounted for 9.03%, 31.55% and 59.42%, respectively. During the study period, the cumulative coverage of enterovirus-A71 vaccine increased year by year, with the proportion of enterovirus-A71 and severe cases both gradually decreasing.@*CONCLUSION@#The current status of hand, foot and mouth disease in Ningbo is still serious. Children under 3-year old (especially male children aged 1 year) were the key population for prevention and control. Vaccination might lead to changes in major pathogenic virus type, of which more attention should be paid to the potential impact on disease surveillance, prevention and control.

Inhibition of CXCR2 alleviates the development of abdominal aortic aneurysm in Apo E-/- mice

ABSTRACT Purpose To investigate the relationship between atherosclerotic abdominal aortic aneurysm (AAA) and CXC chemokine receptor type 2 (CXCR2). Methods Mouse AAA model was established by embedding angiotensin-II pump (1000 ng/kg/min) in ApoE-/- mice. Mice were received SB225002, a selective CXCR2 antagonist, for treatment. Blood pressure was recorded, and CXCR2+ macrophages were examined by flow cytometry analysis. Terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) staining was performed to detect cell apoptosis of abdominal aortic aneurysms. Macrophages were isolated from ApoE-/- mice and treated with Ang II and/or SB225002. Dihydroethidium staining was carried out to determine reactive oxygen species (ROS) activity. Enzyme-linked immunosorbent assay (ELISA) was performed to determine the production of IL-1β and TNF-α. The corresponding gene expressions were measured using real-time polymerase chain reaction (PCR), western blot, and immunohistochemistry staining. Results We found that Ang II activated the expression of CXCR2 in monocytes during the formation of AAA. Inhibition of CXCR2 significantly reduced the size of AAA, attenuated inflammation and phenotypic changes in blood vessels. Ang II-induced macrophages exhibited elevated ROS activity, and elevated levels of 1β and TNF-α, which were then partly abolished by SB225002. Conclusions CXCR2 plays an important role in AAA, suggesting that inhibiting CXCR2 may be a new treatment for AAA.

COVID-19: la pandemia por el nuevo virus SARS-CoV-2

RESUMEN Durante las primeras semanas de 2020 se comenzaron a informar casos de personas con SARS-CoV-2 fuera de China, con un rápido aumento de casos y muertes en todo el mundo. El SARS-CoV-2 es un virus ARN monocatenario positivo, envuelto en una bicapa lipídica derivada de la membrana celular del huésped y constituido por cuatro proteínas estructurales (S, M, E y N), además de una hemaglutinina-esterasa. La unión de la proteína S con el receptor de enzima convertidora de angiotensina 2 (ECA2) permite la entrada del virus a la célula huésped y es una potencial diana terapéutica. El 81% de los enfermos hace cuadro leve; el 14%, grave; y el 5% requiere cuidados intensivos. La fiebre es el síntoma más frecuente, seguido de tos y disnea. La mayoría de los pacientes no presentan leucocitosis pero sí linfopenia, con cultivos de esputo que no muestran otros patógenos. En las biopsias de pulmón de pacientes graves el hallazgo más llamativo es el daño alveolar difuso. Radiológicamente se aprecian patrones de vidrio esmerilado y alveolar, siendo las lesiones de predominio basal, subpleural y posterior, con una distribución periférica multifocal, afectando más el lóbulo inferior derecho. Hay una marcada respuesta inflamatoria, que llega hasta la tormenta de citoquinas, en la que el tratamiento antiinflamatorio con terapia de pulso con metilprednisolona estaría indicado. Aunque no existan estudios en gran escala respecto al uso de cloroquina/hidroxicloroquina, debido a la situación mundial se ha autorizado su uso por su efecto anti SARS-CoV-2 y anti-inflamatorio, el cual puede ser potenciado con el uso de azitromicina.

ABSTRACT During the first weeks of 2020, cases of SARS-CoV-2 began to be reported outside of China, with a rapid increase in cases and deaths worldwide. SARS-CoV-2 is a positive single-stranded RNA virus, encased in a lipid bilayer derived from the host cell membrane and consists of four structural proteins (S, M, E and N), plus a haemagglutinin-sterase. The binding of the S protein to the ECA2 receptor allows the entry of the virus into the host cell and is a potential therapeutic target. 81% of patients develop mild symptoms, 14% have severe symptoms and 5% require intensive care management. Fever is the most frequent symptom, followed by cough and dyspnea. Most patients do not present leukocytosis, but they do present lymphopenia with sputum cultures that do not show other pathogens. In lung biopsies of severe patients, the most noticeable finding is diffuse alveolar damage. Radiologically, ground glass and alveolar patterns are observed; the lesions being predominantly basal, subpleural, and posterior, with a multifocal peripheral distribution, more affecting the right lower lobe. There is a marked inflammatory response, up to the cytokine storm, in which anti-inflammatory treatment with pulse therapy with methylprednisolone would be indicated. Although there are no large-scale studies regarding the use of chloroquine / hydroxychloroquine, due to the global situation, its use has been authorized for its anti-SARS-CoV-2 and anti-inflammatory effect, which can be potentiated with the use of azithromycin.

Psychological distress and its associated risk factors among university students

SUMMARY OBJECTIVE Psychological distress is an important mental health problem among university students. The goal of this study was to determine psychological distress and its associated risk factors among students in the Anhui province. METHODS A cross-sectional study was conducted in a sample of 1304 students. In this study, a self-administered questionnaire consisting of the general demography and General Health Questionnaire (GHQ-12) was completed. Psychological distress was assessed using the GHQ-12-item questionnaire. A dichotomous category split was imposed on the GHQ-12 for the purpose of analysis. A GHQ-12 score of 4 or higher indicated psychological distress. The data were analyzed by SPSS 20.0 system. RESULTS A total of 1304 samples were analyzed in this study. The results indicated that the education level of the father and mother was associated with the students' psychological distress (P<0.001). A significant association was found between high-intensity exercise and low-intensity exercise and psychological distress. However, no significant difference was identified between gender and psychological distress (P=0.173). CONCLUSION The education level of parents, high-intensity exercise, and low-intensity exercise were associated with psychological distress. Our results suggest that it is indispensable to raise awareness of psychological disorders and its associated risk factors among university students. Further studies are required to develop appropriate interventions for high-risk groups.

Objective @# To study the distribution range of the color values of the upper anterior teeth of Uygur youth in the Kashi area of XinJiang as a reference for clinical applications.@*Methods@#Based on the International Commission on Illumination (CIE) L*a*b* color system, the colorimetric values of the anterior teeth of 212 Uygur youths in Xinjiang, Kashi, were analyzed by digital camera colorimetry. There were 105 males and 107 females. The length of the neck to the cutting end of the tooth was measured, and the tooth was evenly divided into thirds. To determine the chromaticity values of the incisors, lateral incisors, cuspids, and middle teeth, 1/3 of the cervical, middle and incisal regions and 9 test areas were measured. @*Results @#The color of the cervical, middle and incisal regions of the same tooth position in Uygur youth in the Kashi area showed the following trends: L* value: middle regions > cervical regions > incisal regions; a* value: cervical regions > incisal regions > middle regions; b* value: cervical regions > middle regions > incisal regions, and the differences were statistically significant (P < 0.05). The value of L* gradually decreased, and the value of a* gradually increased (P < 0.05). There were no significant differences in the a* value of male and female maxillary anterior teeth (P > 0.05). However, there was a significant difference in the b* value between the middle teeth and the incisors, the middle and the incisal regions of the upper maxillary incisors, and the cutting end of the upper maxillary incisors (P < 0.05). @*Conclusions @# There was a significant difference in the color of the cervical, middle and incisal of the same tooth. The upper jaw gradually reduced from the incisors to the sharp teeth, and the color gradually became reddish. The maxillary central incisor was brighter in males than in females, and the middle and incisal regions of the maxillary front teeth were more yellow than in males than in females.
