PurposeMethodsResultsConclusionsCurrent study aimed to understand the distribution and determinants of anterior chamber angle (ACA) and anterior chamber volume (ACV) in Chinese young adults, which can help fill current data gaps and aid in early detection and intervention for high-risk population of primary angle closure glaucoma.This cross-sectional study utilized data from 2014 participants who completed questionnaire and eye examination in September 2021. ACV and ACA were measured using a Pentacam tomographer. Spherical equivalent (SE) was evaluated by autorefractor without cycloplegia. Central corneal thickness (CCT) and biomechanically corrected intraocular pressure (bIOP) were evaluated using Corvis-ST. Axial length (AL), corneal radius (CR), anterior chamber depth (ACD), and white to white were assessed using the IOL Master.A total of 1635 students were included in the analysis. The mean ACV and AVA were 194.74 ± 32.30 μL and 38.81 ± 4.84°, respectively. Males have a larger ACV and wider ACA than females. ACV was positively correlated with ACA (r = 0.24, p < 0.001), and the correlation was stronger for non-myopic students than for myopic students. Multivariable linear regression model showed that AL (β = 2.41), CR (β = –4.12), CCT (β = –0.11), ACD (β = 97.93), and bIOP (β = 0.40) were associated with ACV, and CCT (β = –0.01), CR (β = 0.38), and ACD (β = 7.41) were associated with ACA (all p < 0.05). Random forest model indicated that ACD was the most critical predictor of both ACV and ACA.This study reported the distribution and determinants of ACA and ACV. Deeper ACD was associated with larger ACV and wider ACA. [ABSTRACT FROM AUTHOR]

A single small population of chasmophytic plants is described as M ojiangia oreophila, a monotypic genus in the subtribe Crepidinae, characterised by a unique combination of morphological features, in particular densely long-papillose homomorphic achenes with five main ribs each accompanied by two secondary ribs, coarse brownish pappus bristles, moderately many-flowered capitula, a small involucre with numerous outer phyllaries, perennial rosette herb growth and brown-woolly caudex and leaf axils. Molecular phylogenetic analysis detected that in the nrITS phylogeny M. oreophila forms a clade of its own in the Crepidinae; in the plastid DNA phylogeny it is nested in the clade formed by the hybridogenous genus Faberia, the maternal ancestor of which comes from the Crepidinae and the paternal ancestor from the Lactucinae, where Faberia is placed in nrITS phylogenies. M. oreophila shares several morphological features with Faberia and also shares the expected chromosome number of 2n = 16 with its hitherto unknown maternal ancestor. M. oreophila may therefore be a successor of the maternal ancestor of Faberia . Alternatively, cytonuclear discordance is to be assumed in Mojiangia , caused by chloroplast capture as a result of hybridisation and introgression with Faberia ., Competing Interests: This article does not involve conflicts of interest., (© 2021 Kunming Institute of Botany, Chinese Academy of Sciences.

Objective: To investigate the relationship between c-reactive protein (CRP) and blood pressure in a general population., Methods: We randomly selected 3889 subjects aged 18 - 74 years stratified by gender and age in Baqiao, a rural area of Jiangsu Province. A standardized questionnaire was used to collect information on medical history, smoking, alcohol intake and use of medications. Blood pressure was measured by mercury sphygmomanometer. Serum CRP (hCRP) concentration was measured using a high sensitivity BNprosec immunonephelometric assay. Subjects were divided into 4 groups according to their interquartile range of CRP levers: group Q1 (men hCRP < 2.04 mg/L; women hCRP < 1.80 mg/L); group Q2 (men 2.04 mg/L ≤ hCRP < 3.01 mg/L; women 1.80 mg/L ≤ hCRP < 2.76 mg/L); group Q3 (men 3.01 mg/L ≤ hCRP < 4.14 mg/L; women 2.76 mg/L ≤ hCRP < 3.84 mg/L); and group Q4 (men 4.14 mg/L ≤ hCRP; women 3.84 mg/L ≤ hCRP)., Results: Systolic blood pressure (SBP, adjusted P = 0.016) and pulse pressure (PP, adjusted P = 0.003) of men and PP (adjusted P = 0.002) of women were increased in proportion to increased CRP levels. Diastolic blood pressure was not associated with CRP levels. Multiple stepwise regression analysis showed that logCRP was independently associated with SBP and PP in men and PP in women. hCRP was independently associated with hypertension in men. Compared with group Q1, male people in group Q4 faced a 40.4% (95% confidence interval: 4.9% - 87.9%) higher risk of hypertension., Conclusions: hCRP was independently associated with PP in men and women, and SBP in men. hCRP was independently associated with hypertension in men but not in women in this study population.
