Keratoconus is a blinding eye disease characterized by central or paracentral corneal thinning, forward conical protrusion, and high myopia with irregular astigmatism.There are still no effective radical treatments for keratoconus.Current methods mainly include the prevention and treatment of risk factors, non-surgical optical correction and surgical treatment.The main risk factor prevention and treatment measures include intervention of eye rubbing behavior, symptomatic treatment of allergic diseases and systemic diseases, and correction of poor sleeping position.Non-surgical optical correction uses spectacles or corneal/scleral contact lenses to improve corrected vision.Surgical treatments include intracorneal ring segment implantation to improve corrected vision, corneal collagen cross-linking to increase the biomechanical stiffness of the cornea, and corneal transplantation to treat patients with severe keratoconus or corneal scarring.In addition, femtosecond laser-assisted keratoplasty, lenticule intrastromal keratoplasty combined with corneal collagen cross-linking have been gradually applied in clinical treatment, and tissue engineering based on biosynthetic substitutes, 3D bioprinting technology and cell engineering based on stem cell therapy have provided research prospects for the treatment of keratoconus.This article summarizes the prevention and treatment of clinical risk factors, non-surgical optical correction and surgical treatment, and discusses the research perspective of innovative treatment, in order to provide personalized treatment for patients with keratoconus.

Objective:To compare changes in retinal and choroidal blood flow in the macular area of eyes with idiopathic macular hole (IMH), fellow eyes, and normal eyes. Additionally, the correlation between these blood flow changes and the occurrence and development of IMH.Methods:A cross-sectional study. From January 2023 to January 2024, 47 patients (47 eyes) diagnosed with IMH (IMH group) in Department of Ophthalmology of The Second Hospital of Hebei Medical University were included in the study. The contralateral eye of IMH eyes was assigned to the contralateral eye group. Healthy volunteers with matched gender and age were selected as the normal control group. Swept-source optical coherence tomography angiography was used to acquire the vessel density (VD) of the superficial capillary plexus (SCP) and deep capillary plexus (DCP) in the areas within 0-1 mm and 1-6 mm around the fovea, including the superior, temporal, inferior, and nasal regions. Additionally, the choroidal blood flow area (CBFA) and three-dimensional choroidal vascular index (3D-CVI) were measured. The minimum linear diameter (MLD) and base diameter (BD) of the IMH were manually measured. Spearman correlation analysis was performed to evaluate the correlation between the size of the IMH and the various vascular parameters.Results:Compared with the normal control group, the SCP-VD in the 3rd stage ( t=1.298, P=0.009) and 4th stage ( t=1.264, P<0.000) eyes in the IMH group was significantly decreased, with statistical significance; the DCP-VD ( t=1.958, 2.150, 1.712, 1.667; P=0.027, <0.000, <0.000, <0.000) and 3D-CVI ( t=0.027, 0.030, 0.024, 0.023; P=0.005, 0.003,<0.000, <0.000) in eyes of all stages were significantly decreased, with statistical significance; the CBFA in eyes of stages 2-4 was significantly decreased, with statistical significance ( t=0.027, 0.022, 0.021; P=0.028, 0.002, 0.002). Compared with the contralateral eye group, the DCP-VD and 3D-CVI in the IMH group were significantly reduced, with statistical significance ( Z=?3.289, ?2.704; P=0.001, 0.007). Pairwise comparisons between eyes of different stages in the IMH group showed that SCP-VD was significantly different between stage 2 and stage 4 ( t=1.776, P=0.008); DCP-VD was significantly different between stage 1 and stage 3, and stage 1 and stage 4 ( t=1.685, 1.661; P=0.002, 0.000). Correlation analysis showed that SCP-VD was negatively correlated with MLD and BD ( r=?0.508, ?0.408; P=0.002, 0.014); DCP-VD was negatively correlated with BD ( r=?0.410, P=0.013). Compared with the normal control group, the nasal CBFA in stage 3 and 4 IMH eyes ( t=0.149, 0.145; P=0.005, 0.002), and the nasal 3D-CVI in stage 1 and 3 IMH eyes ( t=0.030, 0.027; P=0.002,<0.000) were significantly decreased, with statistical significance. Conclusions:The SCP-VD, DCP-VD, CBFA, and 3D-CVI in IMH eyes were significantly reduced. SCP-VD showed a negative correlation with MLD and BD, while DCP-VD was only negatively correlated with BD.

Objective:To explore the protective effect and mechanism of irisin on liver injury and mitochondrial dysfunction of hepatocytes in mice with acute necrotizing pancreatitis (ANP).Methods:24 mice were randomly divided into the control group, the ANP group, the irisin group and the cilengitide group, with 6 mice in each group. The ANP group was prepared by intraperitoneal injection of 20% L-arginine. The irisin group was injected with 250 μg/kg of irisin intraperitoneally on the basis of the induction of ANP. The cilengitide group was injected with the integrin receptor αVβ3/5 inhibitor cilengitide at 20 mg/kg on the basis of the treatment of the irisin group. The control group was injected with 0.9% normal saline instead of L-arginine. Routine liver histopathological examination and scoring were performed; immunohistochemical staining was used to detect the level of neutrophil infiltration in liver tissue; the ultrastructure changes of mitochondria were observed under transmission electron microscopy; biochemistry was used to detect the ATP content in liver tissue to reflect the changes in mitochondrial function; the total antioxidant capacity of liver tissue was detected by the ferric reducing/antioxidant power (FRAP) method; the DHE fluorescence probe labeling method was used to detect the accumulation degree of oxygen free radicals in liver tissue.Results:The livers of the control group showed no obvious abnormalities. However, the ANP group, the irisin group and the cilengitide group all had liver tissue damage and infiltration of inflammatory cells in the mice. Compared with the ANP group, the liver pathological score, the number of neutrophil infiltration, and the DHE fluorescence staining density in the irisin group were significantly lower [(3.40±0.72) vs (7.26±1.01) points, (14.67±2.51) vs (33.33±3.51) cells, (16.33±5.03) vs (50.33±10.69) cells], while the above indicators in the cilengitide group were all increased [(7.06±1.55) points, (40.33±5.03) cells, (51.00±12.8) cells]; the ATP content [(296.04±64.6), (54.77±18.05), (109.50±56.61), (40.29±11.68) μmol/gprot], and the antioxidant capacity [(0.19±0.01), (0.10±0.01), (0.17±0.02), (0.11±0.01) mmol/g] in the control group, ANP group, irisin group and cilengitide group changed accordingly. The above differences were statistically significant (all P value <0.05). Transmission electron microscopy observation revealed that the abnormal mitophagy of liver cells in the irisin group restored to normal, while the mitophagy abnormality in the cilengitide group was exacerbated. Conclusions:Irisin could improve the disordered mitochondrial function and oxidative stress in liver cells by acting on integrin receptors αVβ3/5, thereby alleviating liver damage and inflammatory responses in ANP mice.

Objective: To investigate the efficacy, safety, and traditional Chinese medicine (TCM) medication patterns of rituximab (RTX) combined with TCM on treating children with steroid-dependent nephrotic syndrome (SDNS). Methods: One hundred and forty-three children with SDNS who visited the Pediatric Nephrology Department of the First Affiliated Hospital of Henan University of Chinese Medicine from January 2018 to December 2022 were enrolled. A cohort study design was adopted, with " RTX treatment" as the exposure factor. Children who met this exposure factor were assigned to the RTX cohort (RTX, glucocorticoid, immunosuppressive agent, combined with traditional Chinese medicine syndrome differentiation treatment), whereas those who did not were assigned to the basic treatment cohort (glucocorticoid, immunosuppressive agent, combined with traditional Chinese medicine syndrome differentiation treatment ), and followed up for 6 months. The frequency of urinary protein recurrences, urinary protein remission duration, proportion and duration of steroid reduction and cessation, cumulative usage of steroids, proportion of recurrence, recurrence amount of steroid used, efficacy of TCM syndrome, and laboratory and safety indicators after treatment, and height and CD19+ B cell count before and after treatment were compared between the two cohorts. The medication patterns of TCM in the two cohorts were analyzed using frequency statistics, association rule analysis, and systematic clustering analysis. Results: Compared with the basic treatment cohort, the RTX cohort showed a decrease in the frequency of urinary protein recurrence, extended sustained remission of urinary protein, an increase in the proportion of steroid reduction and cessation, a shorter duration of steroid reduction and cessation, a decrease in cumulative steroid dosage, a lower recurrence rate, a decrease in CD19+ B cell count, and a decrease in 24-h urinary total protein quantification and the level of cholesterol (P<0.05). No significant difference in the recurrence amount of steroid used, height, TCM syndrome efficacy, albumin, aspartate transaminase, blood urea nitrogen, platelet count, and safety indicators between the two cohorts. Children with SDNS were mostly characterized by qi and yin deficiency syndrome, followed by spleen and kidney yang deficiency syndrome. A total of 175 TCMs were included, including 28 high-frequency drugs such as Huangqi, Fuling, Gancao, Baizhu, Dangshen, and Jiuyurou. The primary use of medication is to nourish the qi and spleen, nourish the kidney, and warm yang. The analysis of association rules yielded eight binary associations and ten three-phase associations, with Huangqi, Baizhu, Fuling, and Dangshen, being the most closely related. Cluster analysis identified four TCM combinations, primarily focusing on tonifying kidney and replenishing essence, benefiting qi and nourishing yin, and removing blood stasis. Conclusion RTX combined with TCM syndrome differentiation treatment can reduce the recurrence frequency of SDNS, prolong the remission period, reduce the glucocorticoid dosage, and have no marked effect on height growth. No apparent adverse reactions were observed. TCM should focus on nourishing qi and yin while removing blood stasis.
