Humanistic care ability and its influencing factors among Chinese surgical nurses.

Aim: This paper aims to investigate the humanistic care ability among surgical nurses in China and identify its statistically significant influencing factors.

Design: A cross-sectional, descriptive and correlational design was used.

Methods: A total of 210 surgical nurses were recruited from a tertiary public hospital in Wuhu, Anhui Province.

Exogenous stimulation-induced biosynthesis of volatile compounds: Aroma formation of oolong tea at postharvest stage.

Volatile organic compounds (VOCs) are produced by plants responding to biotic and abiotic stresses. According to their biosynthetic sources, induced VOCs are divided into three major classes: terpenoids, phenylpropanoid/benzenoid, and fatty acid derivatives. These compounds with specific aroma characteristics importantly contribute to the aroma quality of oolong tea.

Effects of Hydrogen Peroxide Produced by Catechins on the Aroma of Tea Beverages.

Hydrogen peroxide has a significant effect on the flavor of tea beverages. In this study, the yield of hydrogen peroxide in (-)-epigallocatechin gallate (EGCG) solution was first investigated and found to be significantly enhanced under specific conditions, and the above phenomenon was amplified by the addition of linalool. Then, an aqueous hydrogen peroxide solution was added to a linalool solution and it was found that the concentration of linalool was significantly reduced in the above-reconstituted system.

[An analysis of prognostic factors in 80 myelodysplastic syndrome].

Objective: To investigate the WHO classification, clinical and hematological features and risk group of International Prognostic Scoring System (IPSS) in patients with myelodysplastic syndrome (MDS).

Methods: The diagnosis and classification of MDS patients were defined according to the WHO classification. The clinical manifestations, hemogram, bone marrow biopsy and prognosis were retrospectively analyzed.

Phenolic content and radical scavenging capacity of 31 species of ferns.

The total phenolic content of 31 species of fern plants was determined, and their antioxidant activities were assessed by DPPH radical scavenging analysis.

[A pilot study of spectrum of gene expression of acute leukemia].

Objective: To investigate the gene expression of acute leukemia so as to study the pathogenesis of leukemia.

Methods: Five ml of bone marrow was collected from 22 patients with leukemia, 15 males and 7 females, aged 15-86, 17 with acute myelocytic leukemia, 4 with acute lymphocytic leukemia, and 1 with AHL. Mononuclear cells were isolated.

[Clinical and experimental study of two cases of myelodysplastic syndromes with double isochromosome 20q- anomaly].

Objective: To explore the clinical and laboratory characteristics of two myelodysplastic syndromes (MDS) patients with double isochromosome 20q- anomaly.

Methods: Bone marrow cell chromosome preparations were made with both direct method and short-term culture. Karyotype analysis was performed by R-banding technique, and dual-color FISH (fluorescence in situ hybridization) by using a 20q telomeric probe and a sequence-specific probe for 20q12.

[Abnormalities of the erythrocyte membrane ultrastructure and the membrane proteins in a patient with HEMPAS, alpha thalassemia and complicated diabetes].

Objective: Diagnosis of a case with congenital dyserythropoietic anemia (CDA).

Methods: Routine tests for hemolysis were carried out. The activities of erythrocyte enzymes were measured according to the methods recommended by international committee for standardization in hematology (ICSH).

The effect of Nestorone on gonadotropic cells in pituitary of rats.

The implant containing Nestorone is a promising long-acting contraceptive especially suitable for lactating women. In this study, two experiments were designed to observe the effect of Nestorone on the gonadotropic cells in pituitary of rats for analyzing its antiovulation mechanism. In the first experiment, the ED50 of Nestorone on inhibiting ovulation was found to be 1.
