Mortality from hepatitis B virus (HBV)–related acute‐on‐chronic liver failure (ACLF) is high due to limited treatment options. Preclinical and clinical investigations have proved that with mesenchymal stromal cells (MSCs) beneficial for recovery injury. We hypothesized the outcome of HBV‐related ACLF would be improved by MSC treatment. From 2010 2013, 110 patients were enrolled in this open‐label, nonblinded randomized controlled study. The control group (n = 54) was treated standard medical...

Abstract Background Induction chemotherapy (IC) comprising docetaxel, cisplatin, and fluorouracil (TPF), combined with concurrent chemoradiotherapy (CCRT) effectively improves the survival rate of locally advanced nasopharyngeal carcinoma (LA‐NPC). Selecting patients whose risk tumor recurrence metastasis is high appropriate intensity a concern. We tumor‐node‐metastasis staging load Epstein–Barr virus (EBV) after IC to select individualized strength. Methods The clinical data prognostic...
