Diabetic cataract, a prevalent ocular complication of diabetes mellitus, arises from a complex interplay of pathological mechanisms, with oxidative stress and glycation stress playing central roles. Autophagy, a critical cellular self-protection mechanism, sustains intracellular homeostasis by selectively degrading damaged organelles and misfolded proteins, thereby counteracting the detrimental effects of oxidative and glycation stress under hyperglycemic conditions. Emerging evidence indicates a synergistic interaction between glycation stress and oxidative stress, which may exacerbate autophagic dysfunction and accelerate the onset and progression of diabetic cataract. However, the precise molecular mechanisms underlying this relationship remain incompletely understood. This review systematically examines the regulatory role of autophagy inthe pathogenesis of diabetic cataract, with a particular focus on how autophagic impairment influences disease progression under the combined effects of glycation and oxidative stress. By elucidating these mechanisms, the paper aims to provide novel insights into molecular diagnostic approaches and targeted therapeutic strategies for diabetic cataract.

Objective: To investigate the effect of low level laser on osteoclast and collagen fiber remodeling during the process of tooth retention after tooth movement in rats and to provide the experimental basis for clinical application. Methods : In total, 20 eight-week-old Wistar rats were selected to establish a mesial movement model of the maxillary first molar and then randomly divided into four groups after the appliance was removed. In total, 5 rats were included in each group, including baseline group (without force as blank control), control group (without any intervention after removing the force appliance), retention group (teeth were wrapped with orthodontic ligature wires that were screwed into hemp flower as fixed retention to maintain the space between the first molar and incisor after appliances were removed) and retention and low energy laser irradiation group (teeth were wrapped with the orthodontic ligature wires that were screwed into hemp flower as fixed retention and low energy laser irradiation was applied on days 0, 3, 6, 9 and 12 after appliance removal). Two weeks later, all the rats were sacrificed and the first molar tissue blocks of each group were collected. The distribution of osteoclasts and collagen fiber were studied by HE staining, TRAP staining and Masson staining to illustrate the process of alveolar bone and collagen fiber remodeling. Results : Two weeks after appliances were removed, collagen fibers were deposited on both sides of the root in the baseline group, but no osteoclasts were observed in the distal side of the root. In the control group, collagen fibers on the two sides of the root were not obvious and osteoclasts were active on the distal side. In the retention group, collagen fibers were obvious on the two sides of the root and the osteoclasts on the distal side were less active than the control group. Regarding the retention and low energy laser irradiation group, collagen fibers were significantly obvious and osteoclasts were not seen. The difference was statistically significant between the retention and low energy laser irradiation group and the other three groups (P＜0.05). Conclusion These results suggest that fixed retention with simultaneous low level laser can effectively promote the synthesis of collagen fibers and inhibit the activity of osteoclasts during the process of tooth retention after movement, thus reducing the possibility of molar recurrence.

Objective To explore the effect of sequential and comprehensive preventative measures on the development of premature infants' intelligence.Methods A cohort of 120 premature infants was randomly divided into an observation group and a control group,each of 60.Both groups were given routine premature infant care,but the observation group was additionally provided with sequential and comprehensive preventive intervention.It included neonatal screening,inpatient-outpatient link-up,and their parents' watching CDs explaining early childhood education and health education.All of the infants were followed up from birth to 3 years old.Their adaptive capacity,fine motor skills,language acquisition,gross motor skills and social communication were evaluated at 12,24 and 36 months old using a child intelligence developmental scale for neurological development.Development intelligence quotients (DQs) were calculated and compared.Results After 12 months,significant inter-group differences were observed in adaptability and fine motor control.At 24 and 36 months old there were also significant differences in language skills.At one,two and 3 years old the average DQ of the observation group was significantly higher than that of the control group.Significant within-group differences in average DQ were observed in both groups between 1 and 2 years old,but not between 2 and 3.Conclusion Intervention within two years after birth is critical for premature infants.Timely,sequential,integrated,preventive intervention can promote the development of intelligence and better life quality for premature infants.

G protein-coupled receptors (GPCRs) are the largest cell surface receptor family, which mediates activities of almost all known cellular response to ligands, including hormones release, neurotransmitters and sensory input.GPCRs can promote development and progression of gastric cancer, colorectal cancer, lung cancer and breast cancer and other tumors.Tyrosine kinase receptors (RTKs) are another important family of membrane receptors, which can regulate cell proliferation, differentiation, migration and survival.Overexpression of RTKs has been found in many cancer cells.Therefore, GPCRs and RTKs are equally important in the clinical treatment of cancer therapeutic.However, GPCRs and RTKs are not independent, and they can use common signal transduction.The present study show that crosstalk between GPCRs and RTKs can facilitate migration of lung epithelial cells, increasing survival of nerve cells and promoting tumor occurrence and development.This article mainly focuses on crosstalk between GPCRs and RTKs and their roles in tumorigenesis and oncotherapy.
