Objective:To compare the outcomes of multiple scales, primarily the speech, spatial, and other qualities of hearing scale for parents（SSQ-P）, in children with ipsilateral vs. Contralateral cochleareimplantat ion（CRI）. Methods: A total of 69 children who received cochlear implantation surgery from April 1999 to June 2024 were included. Patients were divided into two groups based on whether the implantation was on the same side. General information such as gender, age, age at initial implantation and reimplantation was collected. The primary caregivers of the children were followed up by telephone using the categories of auditory performance（CAP）, speech intelligibility rating（SIR）, and SSQ-P questionnaires. Statistical methods including stepwise regression, linear regression, and permutation tests were employed to investigate if there were any statistically significant differences in the scores of CAP, SIR, SSQ-P total, SSQ-P speech perception, SSQ-P spatial hearing, and SSQ-P auditory quality dimensions between the ipsilateral and contralateral reimplantation groups. Results:Of the 69 children included, 62 were in the ipsilateral reimplantation group with a mean age of 11.1 years, and 7 were in the contralateral reimplantation group with a mean age of 11.7 years. Statistical analysis showed that patients in the contralateral reimplantation group had significantly lower SSQ-P total scores （P<0.05） and spatial hearing dimension scores （P<0.05） than those in the ipsilateral reimplantation group after controlling for the corresponding confounders. Conclusion:The effect of ipsilateral reimplantation of cochlear implants is superior to that of contralateral reimplantation in terms of overall auditory function and spatial hearing in daily life for children, but the mechanisms require further investigation.

Osteoarthritis, the most common degenerative musculoskeletal disease, has an increasingly heavy burden around the world. In 2019, approximately 530 million people suffered from osteoarthritis, with the age-standardized incidence rate of 492.2 per 100 000, the age-standardized prevalence rate of 6348.3 per 100 000 and the age-standardized rate of disability-adjusted life years (DALYs) of 228.0 per 100 000. The heaviest burden is observed in high-income North America while the fastest growth of burden is observed in high-income Asia Pacific. The age-standardized rate of incidence, prevalence and DALYs in China were 509.8 per 100 000, 6330.1 per 100 000 and 224.8 per 100 000, respectively, which were higher than the average level in Asia. Considering the large and aging population in China, the disease burden will continue to increase and the prevalent number and DALYs in 2044 are expected to be 1.5 times higher than those in 2019. Although osteoarthritis is frequently seen in the elderly, the negative impact on young adults should not be ignored. Besides, postmenopausal women, individuals with high body mass index, and residents in rural and mountainous areas are also at relatively higher risk of osteoarthritis. Osteoarthritis increases the risk of multiple diseases, including cardiovascular diseases, diabetes and psychological cognitive impairment, as well as the sarcopenia and fractures. The increasing disease burdens and medical requirements in China indicate that clinicians have to fully understand the burden and harm of the disease, and conduct initial screening and intervention for the osteoarthritis-related diseases for patients. The long-term goal is to relieve the disease burdens and to improve the quality of life for osteoarthritis patients.

Objective:To construct and evaluate a screening and diagnostic system based on color fundus images and artificial intelligence (AI)-assisted screening for optic neuritis (ON) and non-arteritic anterior ischemic optic neuropathy (NAION).Methods:A diagnostic test study. From 2016 to 2020, 178 cases 267 eyes of NAION patients (NAION group) and 204 cases 346 eyes of ON patients (ON group) were examined and diagnosed in Zhongshan Ophthalmic Center of Sun Yat-sen University; 513 healthy individuals of 1 160 eyes (the normal control group) with normal fundus by visual acuity, intraocular pressure and optical coherence tomography examination were collected from 2018 to 2020. All 2 909 color fundus images were as the data set of the screening and diagnosis system, including 730, 805, and 1 374 images for the NAION group, ON group, and normal control group, respectively. The correctly labeled color fundus images were used as input data, and the EfficientNet-B0 algorithm was selected for model training and validation. Finally, three systems for screening abnormal optic discs, ON, and NAION were constructed. The subject operating characteristic (ROC) curve, area under the ROC (AUC), accuracy, sensitivity, specificity, and heat map were used as indicators of diagnostic efficacy.Results:In the test data set, the AUC for diagnosing the presence of an abnormal optic disc, the presence of ON, and the presence of NAION were 0.967 [95% confidence interval ( CI) 0.947-0.980], 0.964 (95% CI 0.938-0.979), and 0.979 (95% CI 0.958-0.989), respectively. The activation area of the systems were mainly located in the optic disc area in the decision-making process. Conclusion:Abnormal optic disc, ON and NAION, and screening diagnostic systems based on color fundus images have shown accurate and efficient diagnostic performance.

Aging is often accompanied by age-related cataract and concurrent degeneration in brain function and structure.Restoration of vision after cataract surgery not only improves visual function, but also affects brain function and structure.Cataract surgery can enhance the effective transmission of blue light by intrinsically photoreceptive ganglion cells, and increase the secretion of melatonin in vivo, thereby regulating biological rhythm and improving the cognitive level of patients.Melatonin can activate its related molecular pathways, such as Reelin, Notch signaling, etc., affecting the accumulation and deposition of β-amyloid protein, reducing neuronal apoptosis, and playing an important role in a variety of neurodegenerative diseases.Although clinical studies have confirmed that vision restoration after cataract surgery can partially reverse the decline in brain function and structure, the molecular mechanisms involved remain unclear.Based on the eye-brain relationship, this paper reviewed and discussed the effects of vision restoration after cataract surgery on brain function and structure and the potential molecular mechanism, so as to provide new ideas and methods for brain remodeling.

Even so, there are still many surgeons who have achieved success through long-term persistence and high-quality content output, thus increasing the number of patient visits, improving their own ability and industry influence, and bringing a greater sense of professional achievement.

Objective:To measure the anatomical parameters of three-dimensional available space of S 1 and S 2 vestibules on Chinese adults by imaging methods, and discuss their clinical values. Methods:Data of 200 cases of pelvic CT with complete posterior ring were collected from January 2015 to January 2021, included 110 males and 90 females. The ages ranged from 21 to 63 years (average, 40.72±10.70 years). Then the parameters of both the left vestibule and the right vestibule of S 1 and S 2 such as vestibular width, vestibular height and vestibular area were measured by the three-dimensional CT reconstructions. Statistical analyses were performed among the groups which were classified according to the gender, side of vestibule to compare the difference of vestibular morphological characteristics among different groups. Results:The average vestibular area of S 1 was 425.71± 45.07 mm 2 (range, 296.3-604.4 mm 2), which was 449.80±28.62 mm 2 (range, 338.3-604.4 mm 2) in males and 388.25±34.01 mm 2 (range, 296.3-498.4 mm 2) in females. The average vestibular width was 28.52±4.34 mm (range, 17.1-36.3 mm), 31.77±2.33 mm (range, 22.46-36.30 mm) in males and 24.55±2.55 mm (range, 17.1-26.1 mm) in females. The mean vestibular height was 21.05±2.29 mm (range, 17.5-32.0 mm), with 21.34±2.37 mm (range, 18.5-32.0 mm) of men and 20.69±1.60 mm (range, 17.5-25.6 mm) of women. The mean S 2 vestibular area was 230.19±35.57 mm 2 (range, 142.5-297.3 mm 2), which was 258.91±28.04 mm 2 (range, 218.3-297.3 mm 2) in males and 205.61±24.12 mm 2 (range, 142.5-258.6 mm 2) in females. The average vestibular width was 15.94±1.72 mm (range, 12.4-20.3 mm), 16.51±1.59 mm (range, 14.4-20.3 mm) in male and 15.25±1.63 mm (range, 12.4-18.1 mm) in female. The mean vestibular height was 14.30±1.20 mm (range, 12.9-17.8 mm), 15.49±1.46 mm (range, 13.6-17.8 mm) in males and 13.73±0.93 mm (range, 12.9-16.1 mm) in females. There were significant differences in vestibular width, height and area between S 1 and S 2 (vestibular width t=3.934, P< 0.001; vestibular height t=3.692, P< 0.001; vestibular area t=4.816, P< 0.001). There were significant differences in S 1 vestibular width, S 1 vestibular height, S 1 and S 2 vestibular area between male groups and female groups (S 1 vestibular width: t=2.969, P=0.003; S 1 vestibular height: t=0.316, P=0.049; S 1 vestibular area: t=1.975, P=0.049; S 2 vestibular area: t=2.023, P=0.044). While there was no significant difference in S 2 vestibular width and height between the two gender groups. There were significant differences in S 1 and S 2 vestibular width, height and area between male and female groups ( P < 0.001). There were no significant difference in parameters between the left and right values of the same vestibular site. Conclusion:The parameters of S 1 sacral vestibule are larger than that of S 2. It implies that S 1 was more feasible to insert iliosacral screws than S 2; lesser diameter iliosacral screws should be selected to insert into S 2. The female S 1 vestibule is smaller than the male, so the iliosacral screws placement has more stringent requirements on the selection of the insertion point and the direction of the screw. And the surgeon can utilize the intact contralateral sacral vestibule as the damaged side to proceed the iliosacral screw inserted simulation.
