Glaucoma is a group of optic nerve disorders characterized by progressive optic nerve atrophy and visual field defects, which can lead to irreversible blindness. Early diagnosis of glaucoma is essential for preventing visual loss. However, due to the absence of obvious early symptoms, the diagnosis of glaucoma remains challenging. Visual electrophysiological examinations, an objective approach for evaluating visual function, have the potential to be used in the early diagnosis of glaucoma. This review integrates the latest publications to introduce visual electrophysiological examination techniques, including electroretinography(ERG)and visual evoked potential(VEP). It also explores the mechanisms underlying these techniques and their application value in the early diagnosis of glaucoma. In addition, this review summarizes the advantages, limitations, and applicable scenarios of different visual electrophysiological techniques. Finally, the review provides an outlook on the development prospects of visual electrophysiological techniques in the early diagnosis of glaucoma. The findings of this review can assist clinicians in selecting appropriate diagnostic methods, promote the innovation and development of early visual electrophysiological diagnostic techniques for glaucoma, and contribute to reducing the risk of blindness caused by glaucoma.

Objective:To explore the application of virtual augmented reality (AR) technology combined with transcranial Doppler ultrasound (TCD) in nursing teaching of cerebrovascular diseases.Methods:Eighty-six nursing students who interned in the Department of Neurology of The First Affiliated Hospital of Army Medical University from January 2021 to November 2022 were assigned into control group (students of grade 2021) and research group (students of grade 2022). The control group received traditional teaching with AR technology about the anatomy of the cerebral arterial circle, its composition, and adjacent structures. The research group was given AR-assisted teaching combined with TCD-based demonstration and interpretation. At the end of internship, the assessment scores, satisfaction with teaching, clinical decision-making ability, self-learning ability, and problem-solving ability were compared between the two groups. SPSS 23.0 was used to perform the non-parametric test, t test, and chi-square test. Results:The theoretical, practical, and comprehensive ability assessment scores of the research group [90 (89, 96), 95 (90, 96), and 93 (90, 96), respectively] were significantly higher than those of the control group [89 (87, 91), 90 (89, 92), and 91 (89, 94), respectively]. In terms of satisfaction with teaching effects, teaching methods, teaching content, and teaching style, the scores of the research group [16 (15, 18), (5.98±0.91), (3.38±0.52), and 13 (11, 14), respectively] were significantly higher than those of the control group [14 (13, 16), (4.23±0.65), (2.37±0.36), and 13 (10, 14 ), respectively]. The research group showed significantly better independent learning abilities than the control group in information seeking [(4.66±0.71) vs. (4.00±0.61)] and solution seeking [(4.43±0.68) vs. (4.41±0.67)], with no significant differences in the other dimensions between the two groups. The research group was significantly superior to the control group in all problem-solving dimensions: positive orientation [12 (10, 12) vs. 10 (9, 11)], rationality [26 (23, 28) vs. 21 (21, 24)], negative orientation [15 (13, 20) vs. 20 (17, 20)], avoidance style [17 (15, 18) vs. 19 (17, 20)], and impulsivity/neglect style [16 (15, 18) vs. 18 (16, 20)]. For rounds assessment, the research group showed significantly higher scores than the control group in all the items except " communication with patients" [(9.21±0.39) vs. (9.04±0.53)] and "patient satisfaction with nursing students" [(8.92±0.53) vs. (8.73±0.56)].Conclusions:The teaching method based on AR combined with TCD can improve nursing students' knowledge of cerebrovascular diseases, clinical nursing ability, and satisfaction with teaching.

Objective:To improve clinicians' understanding of Multisystem Inflammatory Syndrome in Children (MIS-C) and to reduce missed and misdiagnosis.Methods:The clinical data of a patient with Multisystem inflammatory syndrome in children admitted to Maternal and Child Health Hospital of Hubei Province, Tongji Medical College, Huazhong University of Science and Technology in January 2023 were analyzed retrospectively, together with literature review.Results:A 10-year-old male patient was admitted to hospital with a fever for 5 days. This patient had a history of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection 1 month prior to admission; after admission, he continued to have recurring high fevers, accompanied by abdominal pain and Kawasaki disease like manifestations, shock, multiple organ function impairment, and a significant increase in inflammatory indicators. Finally, the patient was diagnosed with MIS-C, treated with intravenous immunoglobulin, glucocorticoids and aspirin, and discharged with clinical improvement.Conclusion:MIS-C was a novel syndrome with Kawasaki-like manifestations.Currently, the overall prognosis for MIS-C is good, but its pathogenesis is unclear and the therapeutic consensus remains limited. More studies are needed to clarify the best diagnosis and treatment methods and true prognosis.

Objective:To observe any dependence of anticipatory postural adjustment (APA) on the difficulty of fine upper limb tasks and to document any effect of reticulospinal tract (RST) facilitation on APAs during such tasks.Methods:The study′s bivariate mixed design involved 4 different tasks and 3 different priming states. Thirteen healthy, male, right-handed subjects were recruited. They were asked to complete the 4 tasks of reaching, grasping a cup, pinching a card using the thumb or using the little finger, respectively for 10 times 1 in response to two different starting cues delivered through an earphone. Half of the trials with each task were initiated with 114dB white noise to startle and activate the reticulospinal tract (RST), while the others were activated with 80dB beeps as a control. Electromyographic signals were recorded from the bilateral sternocleidomastoid (SCM), lower trapezius (LT), latissimus dorsi (LD), lumbar erector spinae and right anterior deltoid muscles and also from the right flexor and extensor carpi radialis muscles (ECR/FCR). In the subsequent processing the electromyographic time domain and frequency domain indicators were converted into a pre-motor reaction time, a time to muscle peak contraction, an activation latency, and APA or compensatory postural adjustment (CPA) amplitude of the tested muscles. These were compared among the different tasks and stimuli. In addition, the 114dB test tasks were classified as two different priming status as SCM + and SCM - according to whether the sternocleidomastoid muscle (SCM) was activated in advance. Results:After RST activation the pre-motor reaction time and the time to peak contraction of all of the muscles were significantly shortened in all of the tasks. The deltoid muscle reaction times in the SCM + , SCM - and control states were (106.89±43.78)ms, (136.78±48.74)ms and (168.60±73.17)ms, respectively, and those differences are significant. The APA amplitudes of the contralateral LT and ipsilateral LD were significantly greater than normal, but the timing of muscle activation onset and the APA/CPA amplitudes of the ECR/FCR were not affected. The latency in the anticipatory muscle activation of the ECR in the little finger grip task was significantly shorter than that in reaching. Conclusions:The extensor carpi radialis show task-specific early activation in fine tasks of the upper limbs with different difficulties. RST activation can lead to early starting of expected actions, accelerate muscle contraction and increase APA amplitude of some trunk muscles, but it has no significant effect on APA/CPA amplitudes in the forearm muscles.

Objective:To explore any differential effect of training wearing a unilateral exoskeleton on the lower-limb motor function of stroke survivors.Methods:Forty stroke survivors were randomly divided into an exoskeleton group ( n=20) and a control group ( n=20). The control group performed conventional lower extremity exercise training while the exoskeleton group received exoskeleton-assisted lower-limb physical therapy. Each participant received eighteen 40-minute training sessions over three weeks. Before and after the intervention, the walking ability, lower-limb function, balance and ability in the activities of daily living of both groups were evaluated. Integrated electromyography (iEMG) of the rectus femoris and tibialis anterior of both legs was also recorded during sit-to-stand transitions to assess the activation of the affected muscles and the symmetry of bilateral muscle activation. Results:After the three weeks, significant improvement was observed in all of the measurements in both groups, but with the exoskeleton group scoring significantly better on average in functional ambulation category grading (1.63±0.72). Both groups′ iEMGs had also improved significantly compared with before treatment, but the exoskeleton group′s average result was by that time significantly better than the control group′s average.Conclusions:A wearable exoskeleton can effectively improve the rehabilitation of walking, lower limb movement, balance and skill in the activities of daily living of persons with subacute stroke. It better activates the affected lower limb muscles and improves the symmetry of bilateral lower limb muscle activation.

Objective:To observe the reliability and validity of using a head-neck relocation test (HRT) in assessing cervical position sense.Methods:A total of 62 subjects were recruited, including 32 with neck pain and 30 healthy subjects. All received two HRTs conducted by two independent assessors at a first session, and then they received another HRT 24 hours later administered by one of them. The joint position error (JPE) was measured in the four directions of cervical motion: flexion, extension, levorotation and dextrorotation. The intra- and inter-rater reliability was quantified in terms of intra-class correlation coefficients (ICCs) and the difference in JPE between the two groups was also determined for validity.Results:The intra- and inter-rater reliability for the HRT in the four directions had ICC values of 0.603-0.830 and 0.597-0.837 respectively. The corresponding standard error of measurement (SEM) values were 1.52-2.15cm and 1.69-2.09cm, while the minimal detectable change (MDC) values were 4.20-5.97cm and 4.69-5.79cm, respectively. The patients with neck pain had significantly larger JPE in cervical extension and right rotation compared to healthy individuals, on average. And their JPE for cervical extension had an area under the curve (AUC) of the receiver′s operating curve of 0.755.Conclusions:The HRT showed good intra- and inter-rater reliability in assessing cervical joint position sense. The JPE for cervical extension can be used to discriminate those with neck pain from healthy subjects.
