Objective: To investigate the role of programmed death-1 (PD-1), death-ligand 1 (PD-L1), and P16 in patients with head neck squamous cell carcinoma (HNSCC). Methods: A total 95 paraffin-embedded samples tumorous tissue HNSCC were collected. Expression levels PD-1, PD-L1, determined by immunohistochemistry. Results: significantly higher proportion PD-1 among infected human papillomavirus was found. PD-L1 expression is closely associated primary site tumor, postoperative recurrence, survival,...

Pinato prognostic nutritional index (PNI) adequately predicts long-term outcomes of various malignancies. However, its value in predicting laryngeal squamous cell carcinoma (LSCC) is unknown. All patients newly diagnosed with LSCC presenting to the Department Head and Neck Oncology at Sun Yat-sen University Cancer Center between January 1, 1990 July 31, 2010 were eligible. The PNI was calculated as serum albumin (g/L) + 5 × total lymphocyte count/L. Cutoff Finder software program used...

Pyruvate Kinase Deficiency (PKD) and Crigler-Najjar syndrome are rare autosomal recessive liver diseases. PKD is caused by homozygous or compound heterozygous mutations in the PKLR gene, leading to non-spherocytic hereditary hemolytic anemia. On other hand, (CNS-II) characterized loss reduced activity of UDP-glucuronosyltransferase, resulting elevated levels unconjugated bilirubin, which primary cause disease manifestation. To date, there have been no reported cases patients with both...
