Objective:To observe the imaging features of extramacular retinoschisis (EMRS) and paravascular abnormalities (PVA) in myopic patients, and preliminary analyze the differences in age, best corrected visual acuity (BCVA), spherical equivalent (SE), axial length (AL), and subfoveal choroidal thickness (SFCT).Methods:A cross-sectional clinical study. A total of 60 myopia patients with EMRS who were admitted to Department of Ophthalmology of The First Affiliated Hospital of Zhengzhou University from January 2023 to June 2024 were included in the study. There were 18 male cases with 18 eyes and 42 female cases with 42 eyes. Age was (37.57±17.14) years; SE was (-10.76±4.66) D; AL was (28.36±1.87) mm. According to the characteristics of ultra-wide-angle optical coherence tomography images, PVA was divided into perivascular cysts (PC), perivascular microfolds (PM) and perivascular lamellar holes (PLH). According to the splitting level, EMRS can be divided into inner layer, middle layer and outer layer. According to SE, the affected eyes were divided into low myopia group, moderate myopia group and high myopia group. The occurrence of EMRS near optic disc, supratemporal, suprasal and subnasal, as well as the clinical characteristics of patients with EMRS at different locations, levels and forms of PVA were observed. Age, BCVA, SE, AL and SFCT of EMRS patients at different locations and levels were compared by independent sample t test. χ2 test or Fisher exact probability test were used to compare the categorical variables between groups. Results:In 60 eyes, EMRS were located in supratemporal, infratemporal, supranasal, subnasal, and paratopic discs in 36, 43, 15, 13, and 14 eyes, respectively. The EMRS in the inner and outer layers were 59 (98.3%, 59/60) and 35 (58.3%, 35/60) eyes, respectively. PVA was present in 47 eyes (78.3%, 47/60). Among them, PC, PM and PLH were 45, 39 and 18 eyes, respectively. The age of those with paratopic splitting was older than those without paratopic splitting ( t=2.720). Those with temporal splitting had worse BCVA and longer AL than those without splitting ( t=2.139, 2.119). Those with subnasal splitting had worse BCVA, higher myopia, longer AL and thinner SFCT than those without splitting. The differences were statistically significant ( t=2.926, -2.640, 2.635, -3.938; P<0.05). Compared with other types of EMRS, patients with inner EMRS had younger age ( t=-2.383), better BCVA ( t=-4.825), shorter AL ( t=-4.767), lower myopia ( t=4.791), and thicker SFCT ( t=4.791); patients with full-layer EMRS were older ( t=2.419), worse BCVA ( t=3.656), longer AL ( t=2.677), higher degree of myopia ( t=-2.755), and thinner SFCT ( t=-3.283), with statistical significance ( P<0.05). There was significant difference in SFCT among patients with or without PC ( t=-2.396, P<0.05). Compared with eyes without PM and PLH, eyes with PM had worse BCVA, longer AL, higher myopia, and thinner SFCT, and the differences were statistically significant (PM: t=2.514, 3.078, -2.811, -4.205; P<0.05; PLH: t=2.514, 2.992, -2.949, -1.773; P<0.05). Conclusions:EMRS primarily occurs in the temporal side, with the highest frequency in the inner layer. Patients with inner-layer EMRS are younger, have better BCVA, shorter AL, lower myopia, and thicker SFCT, whereas patients with full-layer EMRS exhibit the opposite characteristics.

Objective:To observe and analyze the imaging features of pathologic myopic paravascular abnormalities (PVA) and macular retinoschisis (MRS) and their relationship with clinical features.Methods:A retrospective case series study. A total of 371 eyes of 224 patients with pathological myopia with PVA and/or MRS diagnosed by examination in Department of Ophthalmology of the First Affiliated Hospital of Zhengzhou University from September 2021 to December 2023 were included in the study. There were 74 eyes in 48 males and 297 eyes in 176 females. Age were 54 (49, 61) years; equivalent spherical lens (SE) was -13.375 (-18.00,-10.00) D. Axial length (AL) was 29.84 (28.27, 31.24) mm. According to the features of ultra-wide-angle sweep source optical coherence tomography, PVA morphology was divided into blood vessels and paravascular microfolds, paravascular retinal cysts, paravascular retinal splits and paravascular lamellar macular holes. MRS was divided into inner layer, outer layer and mixed layer according to splitting level, and grouped accordingly. The presence of dome-shaped macula (DSM), internal and external lamellar macular hole, and full lamellar macular hole (FTMH) were recorded. According to whether PVA combined with MRS or not, the affected eyes were divided into PVA group and PVA combined with MRS group. According to whether MRS involved the fovea, the affected eyes were divided into two groups: MRS not involved the fovea group and MRS involved the fovea group. Mann-Whitney U test was used to compare age, SE and AL among different groups. Qualitative data were compared by χ2 test. Results:In 371 eyes, there were 120 eyes in the simple PVA group; in the MRS group, there were 251 eyes, of which 208 eyes were in the PVA combined with MRS group. There were 33, 27, 3, 14, 12, 56, 28, and 7 eyes with or without retinal detachment, choroidal neovascularization, DSM, preretinal membrane, and simple superficial detachment of neuroepithelium in inner lamina, outer lamina, and FTMH, respectively. In 328 eyes with PVA, blood vessels and paravascular microfolds, paravascular retinal cysts, paravascular retinal splits and paravascular lamellar macular holes were 151, 236, 202 and 72 eyes, respectively. There were 142 eyes with single lesion (43.29%, 142/328). There were 186 eyes with 2 or more lesions (56.71%, 186/328). There were 34 eyes in the inner MRS group, 92 eyes in the outer MRS group and 125 eyes in the mixed MRS group, respectively. It involved 155 eyes in the fovea group; 96 eyes in the fovea group were not involved. There were significant differences in the number of PVA eyes between the outer MRS group, the inner MRS group and the mixed MRS group ( χ2=30.614, 28.379; P<0.001). Compared with PVA group, PVA group combined with MRS group was more likely to have two or more PVA lesions, the difference was statistically significant ( χ2=30.535, P<0.001). Compared with the inner MRS group and mixed MRS group, the age of the simple PVA group was younger, and the age of the outer MRS group was older, and the differences were statistically significant ( P<0.05). Compared with the inner MRS group and the outer MRS group, the simple PVA group had short AL, less myopia and better optimal corrected visual acuity (BCVA), while the mixed MRS group had long AL, more myopia and worse BCVA, and the differences were statistically significant ( P<0.05). Compared with the PVA group and the inner MRS group, the fovea was more involved in the outer MRS group and the mixed MRS group, and the difference was statistically significant ( χ2=3.906, 10.836; P<0.05). Those with MRS involved in fovea were older, AL was longer, myopia was more severe, and BCVA was worse ( P<0.001). DSM-associated splits were less likely to involve macula ( P<0.001). Conclusion:PVA and MRS exhibit a variety of presentations, and their imaging features correlate with clinical features.

Acute kidney injury (AKI) has high morbidity and mortality, but effective clinical drugs and management are lacking. Previous studies have suggested that macrophages play a crucial role in the inflammatory response to AKI and may serve as potential therapeutic targets. Emerging evidence has highlighted the importance of forkhead box protein O1 (FoxO1) in mediating macrophage activation and polarization in various diseases, but the specific mechanisms by which FoxO1 regulates macrophages during AKI remain unclear. The present study aimed to investigate the role of FoxO1 in macrophages in the pathogenesis of AKI. We observed a significant upregulation of FoxO1 in kidney macrophages following ischemia-reperfusion (I/R) injury. Additionally, our findings demonstrated that the administration of FoxO1 inhibitor AS1842856-encapsulated liposome (AS-Lipo), mainly acting on macrophages, effectively mitigated renal injury induced by I/R injury in mice. By generating myeloid-specific FoxO1-knockout mice, we further observed that the deficiency of FoxO1 in myeloid cells protected against I/R injury-induced AKI. Furthermore, our study provided evidence of FoxO1's pivotal role in macrophage chemotaxis, inflammation, and migration. Moreover, the impact of FoxO1 on the regulation of macrophage migration was mediated through RhoA guanine nucleotide exchange factor 1 (ARHGEF1), indicating that ARHGEF1 may serve as a potential intermediary between FoxO1 and the activity of the RhoA pathway. Consequently, our findings propose that FoxO1 plays a crucial role as a mediator and biomarker in the context of AKI. Targeting macrophage FoxO1 pharmacologically could potentially offer a promising therapeutic approach for AKI.

Objective To investigate the association between glycated albumin/hemoglobin A1c(GA/HbA1c)and type 2 diabetes mellitus(T2DM)complicated with metabolic associated fatty liver disease(MAFLD).Methods A total of 502 hospitalized T2DM patients were enrolled between January 2022 and December 2023 and divided into T2DM group(n=301)and combined with MAFLD(MAFLD,n=201)group.Clinical data were collected,and Logistic regression analyses were performed to evaluate the relationship between GA/HbA1c and MAFLD.Mediation analysis was conducted to assess the role of blood lipids.Results The MAFLD group had higher levels of drinking,waist-to-hip ratio,body mass index,fasting insulin,fasting C-peptide,insulin resistance index,alanine aminotransferase,aspartate aminotransferase,triglycerides(TG),small dense low-density lipoprotein(sdLDL),and blood uric acid compared to the T2DM group(P<0.05).The age,DM duration,GA,GA/HbA1c,and high-density lipoprotein cholesterol(HDL-C)were lower in the MAFLD group than in the T2DM group(P<0.05).Logistic regression analysis showed that after adjusting for confounding factors,GA/HbA1c was an influencing factor for the occurrence of MAFLD in T2DM patients.Mediation analysis revealed that TG,sdLDL,and HDL-C had significant mediating effects,accounting for 19.3%,12.4%,and 8.5%of the risk association,respectively.Conclusions GA/HbA1c is influencing factor of MAFLD in T2DM patients,with blood lipids showing significant mediating effects,suggesting that GA/HbA1c may serve as a novel indicator for assessing MAFLD risk.

Cancer is one of the leading causes of morbidity and mortality worldwide. Due to population aging, lifestyle variation and other factors, the morbidity and mortality of cancer continue to rise in China, resulting in a serious public health problem threating people's health. In response to this increasingly serious problem, tremendous efforts have been made in China, including the development of a series of policies and measures for specific needs of cancer prevention and treatment. Currently, China's strategy to reduce the disease burden of cancer mainly focuses on primary and secondary prevention. This paper summarizes the current status of disease burden of cancer and the performance of three-grade cancer prevention in China.

In recent years, the incidence of cancer in China has been increasing steadily. Advancing primary prevention measures for cancers could be an effective strategy to curb this trend. Diet has been considered a modifiable and shared risk factor for various cancers. Studying dietary patterns, with consideration of the interactions between foods and nutrients, has a practical implication for cancer prevention. This study provided an overview of dietary pattern extraction methods, summarized the research findings on the association between dietary patterns and cancers in the digestive system, respiratory system, and genitourinary system, and elucidated the potential mechanisms underlying these associations, in order to provide scientific references for future research in this field.
