Artificial intelligence improves accuracy, efficiency, and reliability of a handheld infrared eccentric autorefractor for adult refractometry.

Aim: To evaluate the accuracy, efficiency, and reliability of a handheld infrared eccentric autorefractor (hICA) with artificial intelligence (AI) by comparing its refraction measurements to those recorded using hICA and a clinical table-mounted automatic refractor (TAR).

Methods: A cross-sectional study using three optometers, including hICA with or without AI and TAR, for refractometry of adults (aged 19-49 years old) with no signs of ocular disease or trauma in the absence of cycloplegia. Right and left eye refraction data were recorded, including the spherical equivalent (SE), diopter of spherical power (DS), diopter of cylindrical power (DC) decomposed into vectors J0 and J45, and measurement times.

Recovery of photodegraded rhodamine 6g in ester-containing polymer matrices.

Self-healing, rhodamine 6g, dye-doped polymers are reported. The amplified spontaneous emission (ASE) photodegrades after repeated exposure to 532 nm laser light at 10 Hz. Recovery of the ASE signal is observed in dye-doped thermoplastic polyurethane and glycol-modified poly(ethylene terephthalate); both polymers contain repeating ester groups in their backbone.

[Observation on therapeutic effect of acupuncture intervention combined with hyperbaric oxygen therapy for delayed encephalopathy caused by carbon monoxide poisoning].

Objective: To observe the curative effect of acupuncture intervention combined with hyperbaric oxygen chamber treatment for delayed encephalopathy in 32 carbon monoxide (CO) poisoning patients.

Methods: A total of 62 CO poisoning encephalopathy patients were randomized into control group (n = 30) and acupuncture group (n = 32). Patients of the two groups were all treated with medicines (energy mixture solution, hormones, brain cell activators, calcium ion blockers, anti-inflammatory agents, etc.

[Relation between insulin-like growth factor-1 and insulin resistance in patients with acute stroke].

Objective: To study the changes of plasma insulin-like growth factor -1 (IGF-1) and IGF binding protein 3 (IGFBP3) in patients with acute cerebral infarct (ACI) and acute cerebral hemorrhage (ACH) and the correlation of IGF-1 and IGFBP3 with plasma fasting insulin (FINS) related to insulin resistance (IR) and with insulin sensitive index (ISI).

Methods: The plasma IGF-1, IGFBP3 and FINS of 34 patients with ACI and 40 patients with ACH (within 2 days after onset) were measured by radioimmunoassay. Meanwhile, the fasting blood glucose (GS) of these patients was measured.
