Quantitative analysis of carnosine, anserine, and homocarnosine in skeletal muscle of aquatic species from east China sea.

Histidine-containing dipeptides (HCDs) are a family of non-protein, nitrogen-containing compounds with multiple physiological roles and are mainly present in excitable tissues of vertebrates. The distribution of HCDs in various animal species has been the subject of study for nearly 100 years. The aim of this research was to determine the content of the HCDs in the aquatic species collected from the Zhoushan fishing ground of the East China Sea.

Angiographic characteristics and in-hospital mortality among patients with ST-segment elevation myocardial infarction presenting without typical chest pain: an analysis of China Acute Myocardial Infarction registry.

Background: Patients with ST-segment elevation myocardial infarction (STEMI) who present without typical chest pain are associated with a poor outcome. However, whether angiographic characteristics are related to a higher risk of mortality in this population is unclear. This study aimed to investigate whether the higher mortality risk in patients with STEMI without chest pain could be explained by their "high-risk" angiographic characteristics.

[Prognostic implications of hematopoietic cell transplantation-specific comorbidity index on non-relapse mortality and overall survival after allogeneic hematopoietic stem cell transplantation].

Objective: To study the prognostic implications of hematopoietic cell transplantation-specific comorbidity index (HCT-CI) on non-relapse mortality (NRM) and overall survival (OS) in patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Methods: Clinical data of 161 cases received allo-HSCT from July 2003 to November 2010 were analyzed retrospectively. The prognostic significance of HCT-CI, age, sex, conditioning regimens, disease status before transplantation, graft source and the degree of HLA matches for NRM and OS was conducted by COX regression model.
