Objectives This study aimed to investigate the status of 25-hydroxyvitamin D (25(OH)D) and its association with metabolic syndrome (MS) and different MS components among premenopausal women with systemic lupus erythematosus (SLE) in China. Patients and methods Altogether 113 premenopausal women with SLE and the age-matched healthy cohorts were recruited in this cross-sectional study. Clinical manifestations and laboratory data including serum 25(OH)D concentration were collected. A multivariable analysis was performed to analyze the association of 25(OH)D with MS and its components. Results The prevalence of 25(OH)D deficiency (25(OH)D Conclusion The level of 25(OH)D is associated with MS and its components in premenopausal women with SLE.

The pretilt angles for the optically compensated bend (OCB) mode liquid crystals have been improved using novel patterned dual alignment coating structures in this study. The transition from the splay configuration to the bend configuration can thus be effectively reduced. The dual alignment coating structures consisted of a horizontal alignment polyimide (PI) and a patterned vertical alignment liquid crystal polymer (LCP). Three patterning masks were designed for the photolithography process. The pretilt angles were demonstrated to be increased to 34 degrees for the triangle lattice array-patterned cells. It became 31 degrees for the square lattice array-patterned cells, and 24 degrees for the honeycomb lattice array-patterned cells. The improved pretilt angles were illustrated by the force balance model that can be predicted by the LCP area ratio. The effective control over the pretilt angle could improve the response time to 2 ms when the voltage was ramped up to 5.5 V for the OCB mode liquid crystal devices.
