Whether Primary Bone-Only Oligometastatic Nasopharyngeal Carcinoma Patients Benefit From Radiotherapy to the Bones on the Basis of Palliative Chemotherapy Plus Locoregional Radiotherapy?-A Large-Cohort Retrospective Study.

Objectives: Whether to perform local radiotherapy on metastatic bone for primary bone-only oligometastatic nasopharyngeal carcinoma (NPC) patients remains unclear. Therefore, we analyzed the treatment methods and their survival and developed a prognostic model to predict outcomes and guide personalized treatment.

Materials And Methods: We studied 308 primary bone-only oligometastatic NPC patients who were treated with either palliative chemotherapy (PCT) alone, PCT combined with locoregional radiotherapy (LRRT), or PCT, LRRT, and radiotherapy to metastatic bones (bRT).

Application prospects of the 2BS cell-adapted China fixed rabies virus vaccine strain 2aG4-B40.

Background: Rabies is a fatal zoonotic disease whose pathogenesis has not been fully elucidated, and vaccination is the only effective method for protecting against rabies virus infection. Most inactivated vaccines are produced using Vero cells, which are African green monkey kidney cells, to achieve large-scale production. However, there is a potential carcinogenic risk due to nonhuman DNA contamination.

Paclitaxel liposome, cisplatin and 5-fluorouracil-based induction chemotherapy followed by de-escalated intensity-modulated radiotherapy with concurrent cisplatin in stage IVA-IVB childhood nasopharyngeal carcinoma in endemic area: a phase II, single-arm trial.

Background: Previous studies demonstrated that induction chemotherapy (IC) followed by de-escalated chemoradiotherapy adapted to tumor response was effective in treating childhood nasopharyngeal carcinoma (NPC), but the toxicity profile of this treatment strategy, and whether childhood patients with advanced stages can obtain enough benefits from it requires further investigation.

Methods: We conducted a single-center phase II trial (NCT03020329). All participants received 3 cycles of paclitaxel liposome, cisplatin and 5-fluorouracil (TPF)-based IC.

The map of bone metastasis in nasopharyngeal carcinoma: A real-world study.

Objectives: The aim of this study was to compare the metastatic patterns of synchronous bone metastasis (SBM) and metachronous bone metastasis (MBM) in nasopharyngeal carcinoma (NPC).

Methods: This study included bone metastases in NPC patients from 2005 to 2016 in a Chinese hospital. Cohort 1 was collected from 2005 to 2010 for discovery, and Cohort 2 from 2011 to 2016 for validation.

The role of post-translational modifications in the regulation of MCL1.

Apoptosis is an evolutionarily conserved form of programed cell death (PCD) that has a vital effect on early embryonic development, tissue homeostasis and clearance of damaged cells. Dysregulation of apoptosis can lead to many diseases, such as Alzheimer's disease, cancer, AIDS and heart disease. The anti-apoptotic protein MCL1, a member of the BCL2 family, plays important roles in these physiological and pathological processes.

Clinical significance of CCNE2 protein and mRNA expression in thyroid cancer tissues.

Purpose: Thyroid carcinoma (TC) is the most common endocrinal malignancy worldwide. Cyclin E2 (CCNE2), a member of the cyclin family, acts as a regulatory subunit of cyclin-dependent kinases (CDKs). It controls the transition of quiescent cells into the cell cycle, regulates the G1/S transition, promotes DNA replication, and activates CDK2.

Immunohistochemical basigin expression level in thyroid cancer tissues.

Background: Thyroid cancer (TC) is the most common endocrine malignancy; basigin (also known as BSG) plays a crucial role in tumor cell invasion, metastasis, and angiogenesis. This study was designed to identify the change of BSG expression in TC and its possible potential mechanism.

Methods: The BSG expression levels in TC were demonstrated using data collected from in-house immunohistochemical (IHC), RNA-sequencing (RNA-seq), microarrays, and literatures.

Chiral Second-Harmonic Generation from Monolayer WS/Aluminum Plasmonic Vortex Metalens.

Two-dimensional spiral plasmonic structures have emerged as a versatile approach to generate near-field vortex fields with tunable topological charges. We demonstrate here a far-field approach to observe the chiral second-harmonic generation (SHG) at designated visible wavelengths from a single plasmonic vortex metalens. This metalens comprises an Archimedean spiral slit fabricated on atomically flat aluminum epitaxial film, which allows for precise tuning of plasmonic resonances and subsequent transfer of two-dimensional materials on top of the spiral slit.

Expression level and prospective mechanism of miRNA-99a-3p in head and neck squamous cell carcinoma based on miRNA-chip and miRNA-sequencing data in 1, 167 cases.

Background: The role of miR-99a-3p in Head and neck squamous cell carcinoma (HNSCC) has not been reported. Therefore, in this study, we examined the expression level and its molecular mechanisms of miR-99a-3p in HNSCC.

Materials And Methods: MiR-99a-3p-related miRNA-chip and miRNA-sequencing data were collected.

Controlled synthesis of novel cyanopropyl polysilsesquioxane hollow spheres loaded with highly dispersed Au nanoparticles for catalytic applications.

The design and synthesis of novel cyanopropyl polysilsesquioxane hollow spheres lead to production of a highly active and stable catalyst in the reduction of 4-nitrophenol catalyzed by Au nanoparticles.

Highly porous, water-soluble, superparamagnetic, and biocompatible magnetite nanocrystal clusters for targeted drug delivery.

Magnetic particles have become very promising materials for drug delivery. However, preparation of magnetite particles with high surface area, biocompatibility, strong magnetic response, and suitable particle size still remains a major challenge. In this report, magnetite nanocrystal clusters with high surface areas were fabricated through a solvothermal process by introducing ammonium acetate as a porogen and trisodium citrate as a surface modification agent.

Novel fluorinated polysilsesquioxane hollow spheres: synthesis and application in drug release.

Fluorinated polysilsesquioxane (FPSQ) hollow spheres with a large empty interior were synthesized in an aqueous medium by using (trifluoropropyl)trimethoxysilane as the sole precursor. The drug release applications of these spheres were demonstrated, and the materials have great potential as fluorinated drug release carriers.
