Various configuration types of the foveal avascular zone with related factors in normal Chinese adults with or without myopia assessed by swept-source OCT angiography.

Aim: To describe the morphological characteristics of foveal avascular zone (FAZ) in normal Chinese adults with or without myopia by swept-source optical coherence tomography angiography (SS-OCTA) and analyze the possible associated factors.

Methods: Normal Chinese adults with or without myopia aged between 18 and 60y were recruited into the study. One eye in each individual was randomly selected for scanning using SS-OCTA.

Three new species of (Agaricomycetes, Agaricales, Psathyrellaceae) from the Yanshan Mountains in China.

Three new species, , and , were found and described from Yanshan Mountains in China. The identification is based on morphological observation combined with phylogenetic analysis of ITS-LSU--. This study enriched the species diversity of in Yanshan Mountains and provided important data support for the systematic study of in the future.

Study of retinal vessel oxygen saturation in ischemic and non-ischemic branch retinal vein occlusion.

Aim: To explore how oxygen saturation in retinal blood vessels is altered in ischemic and non-ischemic branch retinal vein occlusion (BRVO).

Methods: Fifty BRVO eyes were divided into ischemic (n=26) and non-ischemic (n=24) groups, based on fundus fluorescein angiography. Healthy individuals (n=52 and n=48, respectively) were also recruited as controls for the two groups.

[Influence of LDAO on the conformation and release of bacteriochlorophyll of peripheral light-harvesting complex (LH2) from Rhodobacter azotoformans].

The aim of this study is to reveal the interaction relationships between lauryl dimethylamine N-oxide (LDAO) and peripheral light-harvesting complex (LH2) as well as the influence of LDAO on structure and function of LH2. In the present work, the effects of LDAO on the conformation and release processes of bacteriochlorophyll (BChl) of LH2 when incubated under different temperature and pH in the presence and absence of LDAO were investigated by spectroscopy. The results indicated that (1) the presence of LDAO resulted in alterations in the conformation, alpha-helix content, and spectra of Tyr and B850 band of LH2 at room temperature and pH 8.

[Function of pancreatic islet beta cells and features of TCM symptoms and syndromes in the non-diabetic first-grade relatives of patients with type 2 diabetes mellitus].

Objective: To study the function of pancreatic islet beta cells, insulin resistance (IR) and features of TCM symptoms and syndromes in the non-diabetic first-grade relatives (ND1GR) of patients with type 2 diabetes mellitus (DM2).

Methods: A total of 68 ND1GR of DM2 patients were enrolled in the observed group and 45 healthy subjects with matched sex, age and body mass index (BMI) but without family history of DM were selected into the control group. Levels of fasting blood glucose (FBG), 2 hrs postprandial glucose (2hPG), fasting insulin (FINS) and 2 hrs postprandial insulin (2h INS) in all the subjects were measured to calculate and compare the IR and beta-cell function of the homeostatic model analog (HOMA-IR and HOMA-beta), and the insulin sensitive index (ISI).
