AIM: To compare the changes in corneal epithelial thickness(CET)after small incision lenticule extraction(SMILE)and femtosecond laser-assisted in situ keratomileusis(FS-LASIK).METHODS: A total of 187 patients(187 eyes)who underwent either SMILE or FS-LASIK at Urumqi Aier Eye Hospital between December 2022 and November 2023 were collected. The patients were divided into SMILE group and FS-LASIK group according to surgical methods. The CET of the patients was measured by optical coherence tomography(OCT)system before surgery and at 1 wk, 1, 3, and 6 mo postoperatively.RESULTS: Changes in corneal epithelial thickness(△CET)in the central, paracentral, and mid-peripheral regions were compared at 6 mo postoperatively. The SMILE group was characterized by the most significant thickening in the central area and the least thickening in the mid-peripheral area; while the FS-LASIK group was characterized by the most significant thickening in the paracentral area and the least thickening in the mid-peripheral region. At 1 wk, 1, 3, and 6 mo postoperatively, within the 0-7 mm corneal area, the △CET for both the SMILE and FS-LASIK groups was correlated with the preoperative spherical equivalent.CONCLUSION: Within 6 mo postoperatively, both SMILE and FS-LASIK showed a similar trend in epithelial thickening but with distinct characteristics. The change in corneal epithelial thickness for both procedures was positively correlated with the preoperative diopter.

Alzheimer's disease (AD) is the major form of dementia in the elderly and is closely related to the toxic effects of microglia sustained activation. In AD, sustained microglial activation triggers impaired synaptic pruning, neuroinflammation, neurotoxicity, and cognitive deficits. Accumulating evidence has demonstrated that aberrant expression of deubiquitinating enzymes is associated with regulating microglia function. Here, we use RNA sequencing to identify a deubiquitinase YOD1 as a regulator of microglial function and AD pathology. Further study showed that YOD1 knockout significantly improved the migration, phagocytosis, and inflammatory response of microglia, thereby improving the cognitive impairment of AD model mice. Through LC-MS/MS analysis combined with Co-IP, we found that Myosin heavy chain 9 (MYH9), a key regulator maintaining microglia homeostasis, is an interacting protein of YOD1. Mechanistically, YOD1 binds to MYH9 and maintains its stability by removing the K48 ubiquitin chain from MYH9, thereby mediating the microglia polarization signaling pathway to mediate microglia homeostasis. Taken together, our study reveals a specific role of microglial YOD1 in mediating microglia homeostasis and AD pathology, which provides a potential strategy for targeting microglia to treat AD.

This article summarizes Academician WANG Yongyan′s experience in the differentiation and treatment of motor neuron disease, which can be categorized into flaccidity syndrome, convulsive syndrome, and fei syndrome according to the clinical manifestations. These three syndromes may coexist, and the condition progressively worsens over time, which is believed to be caused by external pathogenic qi, based on "deficient-qi induced stagnation" , and with "toxins damaging collaterals" as the core etiology and pathogenesis. "Toxins damaging collaterals" involves three levels of qi collaterals, blood collaterals, and fluid collaterals, gradually overlapping and affecting the marrow collaterals. Academician WANG Yongyan′s theory is based on syndrome differentiation, breaking down the boundaries of flaccidity, convulsive, and fei syndromes according to different manifestations of the disease, and using the concept of "combined treatment" for treatment. The clinical presentation of motor neuron disease shows a bottom-up trend in the development of the sanjiao, and the combination of visceral syndrome differentiation and sanjiao syndrome differentiation can grasp the progress of the disease comprehensively. During the process of syndrome differentiation, the focus is on the use of xiang thinking, emphasizing the holistic correlation between diseases and syndromes and the integrated effect of reductionist analysis. Treatment is based on xiang differentiation and individualized treatment. The mid-stage of motor neuron disease is the key time point for the treatment of this disease. Based on the clinical symptoms of flaccidity, convulsive, and fei syndromes, where treatment should focus on reinforcing the spleen and kidney, combining moxibustion with herbal medicine. While targeting the disease, treatment should comprehensively apply the methods of "promoting, supplementing, softening, and warming" to eliminate toxins and unblock collaterals, and restore the neural regulation of the brain and spinal cord.

The "body schema" of acupuncture and moxibustion is centered on the meridian system and represents a corporeal perspective of "heaven-connection", embodying the harmony between nature and humanity. It integrates the cyclic schema of the heavenly cycling, the meridian growth and decline schema of the guaqi theory, the twelve zodiac demarcation schema from astrological and astronomical studies, and the nine-palace and eight-trigrams schema of temporal and spatial locations. It presents the theoretical origins of the harmony between nature and humanity in acupuncture and moxibustion along with medical thoughts under the background of social concepts. The numerical arts of acupoint number and acupuncture-moxibustion quantity, those of acupuncture-moxibustion time and taboos, as well as the time-based acupuncture-moxibustion patterns, all of these thoroughly reflect the application of the body schema of acupuncture and moxibustion by early medical practitioners in ancient time. The study on the body philosophy in acupuncture and moxibustion should start from the original appearance of early classical acupuncture-moxibustion theory, trace the source of body philosophy of acupuncture and moxibustion, seek the truth of temporal body medicine, and perfect the body philosophy research of contemporary acupuncture and moxibustion, so as to improve the dual attributes of acupuncture and moxibustion in humanities and science.
