Objective: To investigate the differences in ocular surface characteristics, tear film quality, and the incidence of dry eye disease (DED) between Systemic Lupus Erythematosus (SLE) patients and healthy populations.

Methods: This age and gender-matched cross-sectional study included 96 SLE patients without secondary Sjögren's syndrome (SS) and 72 healthy subjects. The Ocular Surface Disease Index (OSDI), tear meniscus height (TMH), non-invasive tear film breakup time (NIKBUT), meibography, and tear film lipid layer grade were assessed.

Article Synopsis
  • - A study analyzed four automobile manufacturing companies in Zhejiang Province to identify how volatile organic compounds (VOCs) are produced and emitted during their production processes.
  • - The coating processes were found to be the primary sources of VOCs, with solvent-based cleaning agents also contributing significantly to emissions.
  • - In 2017, the automobile manufacturing industry in Zhejiang Province produced an estimated 2,425.84 tons of VOCs, with 1,627.54 tons actually emitted into the environment.

Purpose: To investigate the incidence, severity, and influencing factors of dry eye in systemic lupus erythematosus (SLE) patients without secondary Sjögren's syndrome (sSS).

Methods: A total of 78 patients who were diagnosed with systemic lupus erythematosus and met inclusion criteria were selected as the study subjects in this cross-sectional study. Tear meniscus height (TMH) and noninvasive Keratograph tear breakup time (NIKBUT) including NIKBUT-first and NIKBUT-average of the subjects were measured using a noninvasive ocular analyzer, the Keratograph 5M (Oculus, Wetzlar, Germany).

The present study aimed to evaluate the efficacy, predictability and safety of astigmatic keratotomy (AK) combined with scleral tunnel incisions in the treatment of high astigmatism after penetrating keratoplasty (PKP). Paired AK combined with scleral tunnel incisions was performed at the steep astigmatic meridian in 8 eyes of 8 patients with high keratometric astigmatism [>5.0 diopters (D)] after PKP.

Background: Epidemiological studies have evaluated the association between Apolipoprotein E (APOE) gene ε2/ε3/ε4 polymorphism and glaucoma susceptibility. However, the published data are still inconclusive. The aim of the present study is to evaluate the impact of APOE gene ε2/ε3/ε4 polymorphism on glaucoma risk by using meta-analysis.

The layered double hydroxides (LDHs) containing nitrate as the interlayer anion has a high anion-exchange capacity in the presence of appropriate anions. In the light of this, ZnAl-NO(3) LDHs have been employed to remove chloride ion from aqueous solution in a batch mode. The influences of conditions for chloride ion uptake, including dosage of LDHs, pH of aqueous solution, and temperature on anion-exchange have been investigated, respectively.
