Introduction: Ametropias or refractive errors are pathologies commonly encountered in ophthalmology characterized by the projection on the retina of a blurry image. There are several types of ametropia and each of them has a specific means of correction. In the literature, numerous data have been reported on the issue through studies that were mostly carried out on infant populations. To better treat ametropia in a more formal way, it is important to know their general characteristics within a larger population, hence the present investigation, the aim of which is to carry out an epidemiological study of ametropia at the Kati University Hospital-BSS. Materials and Methods: The study was carried out at Kati University Hospital-BSS between January 1 and December 31, 2022 and included 663 ametropic patients of all ages. Results: During the study period, 663 cases of ametropia were diagnosed out of 1678 new consultations, representing an incidence of 39.51%. Patients aged between 21 and 40 years were more affected. Depending on the type, these ametropias were dominated by compound astigmatism with 68.75% followed by isolated hyperopia and isolated astigmatism. Visual fatigue was the most mentioned reason for consultation. The female gender was in the majority with 70.9%. Low ametropia (Discussion: The growing visual needs of young people, especially with new information and communication technologies, would push them to consult the ophthalmologist more, and therefore to want optical correction in the event of a refractive anomaly, which would partly explain their high frequency in this age group. Conclusion: It is important to know the general characteristics of ametropia in the general population in order to improve the quality of life of patients affected by it through efficient therapeutic solutions.

The action mechanism by which C1q/tumor necrosis factor-related protein-6 alleviates cerebral ischemia/reperfusion injury in diabetic mice

引用

Neural Regeneration Research 2024年第9期19卷 2019-2026页

作者： Bo Zhao Mei Li Bingyu Li Yanan Li Qianni Shen Jiabao Hou Yang Wu Lijuan Gu Wenwei Gao Department of Anesthesiology Renmin Hospital of Wuhan UniversityWuhanHubei ProvinceChina Central Laboratory Renmin Hospital of Wuhan UniversityWuhanHubei ProvinceChina Department of Critical care Medicine Renmin Hospital of Wuhan UniversityWuhanHubei ProvinceChina

Studies have shown that C1q/tumor necrosis factor-related protein-6 (CTRP6) can alleviate renal ischemia/reperfusion injury in mice. However, its role in the brain remains poorly understood. To investigate the role of CTRP6 in cerebral ischemia/reperfusion injury associated with diabetes mellitus, a diabetes mellitus mouse model of cerebral ischemia/reperfusion injury was established by occlusion of the middle cerebral artery. To overexpress CTRP6 in the brain, an adeno-associated virus carrying CTRP6 was injected into the lateral ventricle. The result was that oxygen injury and inflammation in brain tissue were clearly attenuated, and the number of neurons was greatly reduced. In vitro experiments showed that CTRP6 knockout exacerbated oxidative damage, inflammatory reaction, and apoptosis in cerebral cortical neurons in high glucose hypoxia-simulated diabetic cerebral ischemia/reperfusion injury. CTRP6 overexpression enhanced the sirtuin-1 signaling pathway in diabetic brains after ischemia/reperfusion injury. To investigate the mechanism underlying these effects, we examined mice with depletion of brain tissue-specific sirtuin-1. CTRP6-like protection was achieved by activating the sirtuin-1 signaling pathway. Taken together, these results indicate that CTRP6 likely attenuates cerebral ischemia/reperfusion injury through activation of the sirtuin-1 signaling pathway.
