This study aims to address the dynamic changes in oral microbiome following cancer treatment and their prognostic implications in NPC patients.

Patients And Methods: Unstimulated whole saliva samples were collected from 23 NPC patients before and after treatment, with an average of 2.

lncRNA-NEF regulates hepatic stellate cells proliferation, cell cycle, apoptosis and ECM synthesis through the ERK1/2/c-Fos axis.

In this study, we investigated the role of lncRNA-NEF in modulating hepatic stellate cell (HSC) activation, a key process in liver fibrosis. Using the GSE78160 dataset, we identified lncRNA-NEF as downregulated in liver cirrhosis patients. Gene Ontology and KEGG analyses implicated it in transcriptional regulation and cell cycle control.

Retiform hemangioendothelioma (RH) is a type of low-grade malignant angiosarcoma. It commonly involves the skin and subcutaneous tissue of the lower extremities, but a few cases have been reported in the gut. However, hepatic RH has not been previously reported.

[Acteoside promotes autophagy and apoptosis of hepatoma cells by regulating JNK signaling pathway].

This study explored the molecular mechanism of acteoside against hepatoma 22(H22) tumor in mice through c-Jun N-terminal kinase(JNK) signaling pathway. H22 cells were subcutaneously inoculated in 50 male BALB/c mice, and then the model mice were classified into model group, low-dose, medium-dose, and high-dose acteoside groups, and cisplatin group. The administration lasted 2 weeks for each group(5 consecutive days/week).

Expression and Correlation of MIF and ERK1/2 in Liver Cirrhosis and Hepatocellular Carcinoma Induced by Hepatitis B.

Objective: To detect expression and phosphorylation level of macrophage migration inhibitor (MIF) and extracellular-regulated kinases 1 and 2 (ERK1/2) in hepatitis B-induced liver cirrhosis (HBILC) and hepatocellular carcinoma (HCC) with a background of HBILC and analyze the correlation of MIF and ERK1/2 with HBILC and HCC.

Methods: Twenty cases of normal liver tissues were collected as a control group, and 48 specimens of HBILC tissues and 48 specimens of HCC tissues were collected as the experimental group, which were assigned as the HBILC group and HCC group, respectively. All tissue specimens were processed into tissue chips.

Prognostic value of the immunohistochemical score based on four markers in head and neck squamous cell carcinoma.

Purpose: Head and neck squamous cell carcinoma (HNSCC) ranks sixth among all cancers globally regarding morbidity, and it has a poor prognosis, high mortality, and highly aggressive properties. In this study, we established a model for predicting prognosis based on immunohistochemical (IHC) scores.

Methods: Data on 402 HNSCC cases were collected, the glmnet Cox proportional hazards model was used, risk factors were analyzed for predicting the prognosis of survival, and the IHC score was established.

Background: Endometrial stromal tumours are uncommon tumours of the uterus. They mainly occur in perimenopausal women. Tumours with typical clinicopathological features do not usually pose diagnostic problems.

Effect of prophylactic gastrostomy on nutritional and clinical outcomes in patients with head and neck cancer.

Background: We aimed to identify which enteral feeding method was most beneficial for patients and compare clinical outcomes, quality of life, and complication rates by assessing patients who underwent prophylactic percutaneous endoscopic gastrostomy (pPEG) tube, reactive percutaneous endoscopic gastrostomy (rPEG) tube or reactive nasogastric tube (rNGT) insertion.

Methods: Patients with head and neck cancers (HNCs) were enrolled between April 1, 2013 and April 17, 2019 (n = 335; 296 males, 39 females). Data concerning patient characteristics and treatment modalities were extracted from the medical records.

Circulating Plasma Epstein-Barr Virus DNA Load During the Follow-up Periods Predicts Recurrence and Metastasis in Nasopharyngeal Carcinoma.

Background: Epstein-Barr virus DNA (EBV DNA) load has been identified as a prognostic factor in nasopharyngeal carcinoma (NPC), whereas the dynamic changes in the long period have not been explored. In this study, we evaluated EBV DNA kinetics and its role in the survival.

Methods: We conducted a retrospective review of 900 NPC patients.

Explore the correlation between cerebral vessel characteristics with cognitive impairment among elder individuals: a community study from China.

Background: Brain Magnetic Resonance Imaging (MRI) examination of cerebral small vessel disease (CSVD) may help screen vascular cognitive impairment. A recently estimated CSVD score system was suggested to capture the overall CSVD burden. The study aimed to detect the association between systemic evaluation score of cerebral vascular imaging parameters with cognitive functions.

Prognostic Value of an Immunohistochemical Signature in Patients With Head and Neck Mucosal Melanoma.

Purpose: We aimed to develop a prognostic immunohistochemistry (IHC) signature for patients with head and neck mucosal melanoma (MMHN).

Methods: In total, 190 patients with nonmetastatic MMHN with complete clinical and pathological data before treatment were included in our retrospective study.

Results: We extracted five IHC markers associated with overall survival (OS) and then constructed a signature in the training set (n=116) with the least absolute shrinkage and selection operator (LASSO) regression model.

Clinical outcomes and patterns of failure of head and neck mucosal melanoma treated with multiple treatment modalities.

Objectives: The study aims to analyze the clinical characteristics of head and neck mucosal melanoma (MMHN) and the effects of multiple treatment modalities on distant metastasis, recurrence and survival rates to provide a reference for the individualized treatment of MMHN.

Methods: We retrospectively reviewed 262 patients with stage III-IVb MMHN treated from March 1986 to November 2018 at our cancer center.

Results: The median follow-up time was 34.

Objectives: We aimed to understand the clinical characteristics and better predict the prognosis of patients with mucosal melanoma of the head and neck (MMHN) using a nomogram.

Methods: Three hundred patients with nometastatic MMHN were included. Multivariable Cox regression was performed to analyze independent prognostic factors for overall survival (OS), disease-free survival (DFS), distant metastasis-free survival (DMFS), and locoregional relapse-free survival (LRRFS), and these factors were used to develop a nomogram.

Endoscopic surgery compared with intensity-modulated radiotherapy in resectable locally recurrent nasopharyngeal carcinoma: a multicentre, open-label, randomised, controlled, phase 3 trial.

Background: The role of surgery compared with reirradiation in the primary treatment of patients with resectable, locally recurrent nasopharyngeal carcinoma (NPC) who have previously received radiotherapy is a matter of debate. In this trial, we compared the efficacy and safety outcomes of salvage endoscopic surgery versus intensity-modulated radiotherapy (IMRT) in patients with resectable locally recurrent NPC.

Methods: This multicentre, open-label, randomised, controlled, phase 3 trial was done in three hospitals in southern China.

Toxicological responses, bioaccumulation, and metabolic fate of triclosan in Chlamydomonas reinhardtii.

Triclosan (TCS) is a broad-spectrum antimicrobial agent that is broadly used in personal care products. It has been shown to cause the contamination of a variety of aquatic environments. Since algae has been the primary producers of aquatic ecosystems, understanding the toxicological mechanisms and the metabolic fate of TCS is vital for assessing its risk in an aquatic environment.

Detection of methylation status of Epstein-Barr virus DNA C promoter in the diagnosis of nasopharyngeal carcinoma.

The detection of Epstein-Barr virus (EBV) DNA load in nasopharyngeal (NP) brushing samples for diagnosis of nasopharyngeal carcinoma (NPC) has attracted great attention. Further improvements that eliminate the need for clinical settings will greatly extend its application. A total of 250 participants were recruited to obtain NP brushing samples.

Development and external validation of a nomogram for predicting the overall survival of patients with stage II nasopharyngeal carcinoma after curative treatment.

To facilitate decision-making support for individual patients, development and external validation of a nomogram was undertaken to reveal prognostic factors and predict the value of concurrent chemoradiotherapy (CCRT) compared with radiotherapy (RT) for stage-II nasopharyngeal carcinoma (NPC) patients.
