Methods: We retrospectively analyzed 714 patients with lung cancer BMs.

Epidemiological and clinical characteristics of congenital pseudarthrosis of the tibia in China.

Red Cell Distribution Width to Platelet Ratio Is Associated with Increasing In-Hospital Mortality in Critically Ill Patients with Acute Kidney Injury.

Background: Inflammation plays a key role in the pathophysiology and progression of acute kidney injury (AKI). Red cell distribution width (RDW) to platelet ratio (RPR) is a novel inflammatory index, and its prognostic effect on critically ill patients with AKI is rarely investigated. This work is aimed at investigating the association between RPR and in-hospital mortality in these patients.

LCZ696 Possesses a Protective Effect Against Homocysteine (Hcy)-Induced Impairment of Blood-Brain Barrier (BBB) Integrity by Increasing Occludin, Mediated by the Inhibition of Egr-1.

Homocysteine (Hcy) is a non-essential amino acid produced from methionine. It has been reported that high concentrations of Hcy are related to the pathogenesis of neurodegenerative diseases and induce the disruption of the blood-brain barrier (BBB) by triggering oxidative stress and inflammation. LCZ696 is a novel antihypertensive agent that has been recently reported to possess promising anti-inflammatory properties.

Protective effect of exosomes derived from bone marrow mesenchymal stem cells on rats with diabetic nephropathy and its possible mechanism.

Objective: To investigate the effect of exosomes derived from bone marrow mesenchymal stem cells (BMMSC-Exos) on diabetic nephropathy (DN) rats and its possible mechanism.

Methods: Thirty rats were divided into the following three groups of 10 rats each: the NC group (normal rats), the DN group (rats with DN), and the BM group (DN rats injected with BMMSC-Exo). Blood glucose level, renal function, blood lipid level, and plasma viscosity of the rats were detected.

Role of exosomal miRNAs in brain metastasis affected by radiotherapy.

In oncogenesis and development of malignant tumor, microRNAs (miRNAs) regulate the complex gene expression associated with the tumor pathogenesis. Currently, only few studies have been conducted to identify miRNAs and the potential pathways involved in the pathogenesis of brain metastasis in patients who underwent radiotherapy, especially miRNAs in the plasma exosomes. Therefore, this study is aimed to use small RNA analysis to identify miRNAs and their potential target genes in plasma exosomes during the initiation and development of brain metastasis in patients who underwent radiotherapy.

GPR120 Agonist GW9508 Ameliorated Cellular Senescence Induced by ox-LDL.

Oxidized low-density lipoprotein (ox-LDL)-induced endothelial senescence is involved in the pathogenesis of atherosclerosis and many cardiovascular diseases. G-protein-coupled receptor 120 (GPR120), a type of orphan G-protein-coupled receptors (GPRs), plays a vital role in mediating anti-inflammatory and insulin-sensitizing effects. The biological function of GPR120 in vascular endothelial cells is largely unknown.

Tocilizumab exerts anti-inflammatory activity in six critically ill COVID-19 patients: a retrospective analysis.

Background: Coronavirus disease 2019 (COVID-19) has become a worldwide pandemic, affecting countries across the globe. With no current vaccine, treatment is still a critical intervention for minimizing morbidity and preventing disease-specific mortality. This study aimed to assess the clinical outcomes of critically ill COVID-19 patients using Tocilizumab treatment to provide recommendations for the treatment of COVID-19 patients with severe disease.

Correlation of intensity-modulated radiation therapy at a specific radiation dose with the prognosis of nasal mucous damage after radiotherapy.

Objective of the present study was to investigate the tolerant radiation dose of nasal mucosa by observing and analyzing patients who received intensity-modulated radiation therapy (IMRT). Patients with nasopharyngeal carcinoma (N = 66) were selected for this study. The modified saccharin assay, endoscopy test, magnetic resonance imaging, and sino-nasal outcome test-20 (SNOT-20) survey were performed for the patients before and at 0 (T0), 3 (T1), 6 (T2), and 12 (T3) months after radiotherapy.

Identification of miRNA signatures in serum exosomes as a potential biomarker after radiotherapy treatment in glioma patients.

Despite development in therapies, the high recurrence and low positivity of biomarkers for diagnosis still result in glioma with high mortality. In this study, we aimed to identify a potential miRNA signature to evaluate the effect of radiotherapy in glioma patients. MicroRNA (miRNA) sequencing was performed on miRNAs isolated from serum exosomes in a cohort of glioma patients before and after radiotherapy.

[The surrounding radiation dose of iodine-125 seeds on normal larynx tissue in rabbits].

To monitor the change of the radiation dose of the rabbits which were implanted rasioactive 125I seed into the normal laryngeal tiseue at different time,and to evaluate the safety of radiation protection. Sixty New Zwaland rabbits, weighing 2.15-2.

Prospective Randomized Study of Ultrasound-Guided Foam Sclerotherapy Combined with Great Saphenous Vein High Ligation in the Treatment of Severe Lower Extremity Varicosis.

Background: To evaluate the effect of ultrasound-guided foam sclerotherapy (UGFS) in a single session combined with great saphenous vein (GSV) high ligation for severe lower extremity varicosis classified as C4-C6, compared with GSV stripping plus multistab avulsion or transilluminated powered phlebectomy (TIPP).

Methods: From January 2012 to December 2014, 177 patients with primary GSV insufficiency, classified as C4-C6, were randomized into the UGFS group or the control group. The UGFS group was managed by GSV high ligation and foam sclerotherapy in one session under the surveillance of ultrasonography, whereas the control group received GSV high ligation and stripping combined with multistab avulsion or TIPP.

A Successfully Treated Metastatic Choriocarcinoma Coexistent With Pregnancy: A Case Report of a 4-Year Follow-Up.

Gestational choriocarcinoma ended with a successful parturition is extremely rare, especially in cases where multiple metastases occurred.A 29-year-old Chinese primigravida was admitted with vaginal bleeding at 32 gestational week, and diagnosed with gestational choriocarcinoma with vaginal, pulmonary, and cerebral metastasis after pathological, and imaging examination. At 33 gestational week, a healthy infant was delivered by cesarean section.

The value of model for end-stage liver disease and Child-Turcotte-Pugh scores over time in evaluating the prognosis of patients with decompensated cirrhosis: experience in the Chinese mainland.

Aim: In addition to the model for end-stage liver disease (MELD) and Child-Turcotte-Pugh (CTP) score, the change in MELD score (DeltaMELD) and CTP (DeltaCTP) over time, as well as the modified CTP score, have been proposed as predictive factors for patients with advanced liver cirrhosis. We investigated the ability of the above scoring systems to predict the outcome of decompensated cirrhosis in the Chinese mainland.

Methods: A cohort of 160 patients with advanced liver cirrhosis who were followed up were studied prospectively.
