Homeostasis and energy and substance metabolism reprogramming shape various tumor microenvironment to sustain cancer stemness, self-plasticity and treatment resistance. Aiming at them, a lipid-based pharmaceutical loaded with CaO₂ and glucose oxidase (GOx) (LipoCaO₂/GOx, LCG) has been obtained to disrupt calcium homeostasis and interfere with glycometabolism. The loaded GOx can decompose glucose into H₂O₂ and gluconic acid, thus competing with anaerobic glycolysis to hamper lactic acid (LA) secretion. The obtained gluconic acid further deprives CaO₂ to produce H₂O₂ and release Ca²⁺, disrupting Ca²⁺ homeostasis, which synergizes with GOx-mediated glycometabolism interference to deplete glutathione (GSH) and yield reactive oxygen species (ROS). Systematical experiments reveal that these sequential multifaceted events unlocked by Ca²⁺ homeostasis disruption and glycometabolism interference, ROS production and LA inhibition, successfully enhance cancer immunogenic deaths of breast cancer cells, hamper regulatory T cells (Tregs) infiltration and promote CD8⁺ T recruitment, which receives a considerably-inhibited outcome against breast cancer progression. Collectively, this calcium homeostasis disruption glycometabolism interference strategy effectively combines ion interference therapy with starvation therapy to eventually evoke an effective anti-tumor immune environment, which represents in the field of biomedical research.

BACKGROUND:As the end bearing joint of the human body,the ankle joint bears the top-down pressure of the body,which leads to the ankle joint is easy to be damaged in the movement,can induce functional ankle instability,which negatively affects daily life.The study of lower extremity biomechanics in patients with functional ankle instability during counter movement jump is of great significance for scientific training,prevention of ankle injury,and clinical rehabilitation after injury. OBJECTIVE:To investigate the kinetics and kinematics of lower limbs in the longitudinal jumping of functional ankle instability population. METHODS:From March to September 2023,15 male patients with functional ankle instability and 15 healthy people,aged 22-28 years old,were recruited in Soochow University.All subjects completed counter movement jump experiment.Vicon infrared high-speed motion capture system and Kistler three-dimensional force measuring table were used to simultaneously collect the lower limb kinematics and kinetics indexes of the two groups of subjects at the take-off stage of counter movement jump,the instant off the ground,the initial landing moment and the peak moment of vertical ground reaction force. RESULTS AND CONCLUSION:(1)At the instant off the ground,the affected side of the functional ankle instability group showed smaller knee internal rotation moment(P=0.020)and smaller ankle internal rotation moment(P=0.009)compared with the affected side of the healthy control group.(2)At the moment of landing,the affected side of the functional ankle instability group showed a smaller hip flexion angle than the affected side of the healthy control group(P=0.039).Compared with the healthy control group,functional ankle instability group showed smaller hip abduction angle(P=0.022),smaller knee varus angle(P=0.010),larger knee external rotation angle(P=0.021),smaller ankle varus angle(P=0.004),and smaller external ankle rotation angle(P=0.008).(3)At the peak of vertical ground reaction force,functional ankle instability group showed a smaller ankle varus angle than healthy control group(P=0.044).(4)The results showed that the lower limb biomechanical characteristics of the patients with functional ankle instability were abnormal compared with the healthy people during counter movement jump,which mainly showed the changes of the kinematics and kinetics indexes of the lower limb joints in the sagittal plane and the frontal plane at the moment of lift-off and landing.These changes reflect that people with functional ankle instability adopt rigid take-off and landing patterns when performing counter movement jump,tend to transfer the load of the affected ankle joint to other joints of the lower limb,and show compensatory phenomenon of the healthy lower limb.Therefore,detection and correction of abnormal biomechanical features should be a part of rehabilitation training for those with functional ankle instability.

Objective To explore the regulatory effect of long non-coding RNA HOX transcript anti-sense RNA(lnRNA HOTAIR)targeting tuberous sclerosis complex 1(TSC1)on podocyte injury in diabetic nephropathy(DN).Methods Mice podocyte MPC5 were divided into 6 groups:the control group,the high glucose group(the HG group),the HG+si-NC group,the HG+si-HOTAIR group,the HG+si-HOTAIR+sh-NC group,and the HG+si-HOTAIR+sh-TSC1 group.qPCR was used to detect the levels of lnRNA HO-TAIR and TSC1 mRNA.Cell viability was detected by cell counting kit-8(CCK-8),and apoptosis was detec-ted by flow cytometry.ELISA was used to detect the levels of inflammatory factors[IL-6,tumor necrosis fac-tor-α(TNF-α)]and the levels of oxidative stress indicators[reactive oxygen species(ROS),malondialdehyde(MDA),superoxide dismutase(SOD)]were detected by corresponding reagent kit.Results Compared with the control group,the levels of lnRNA HOTAIR,apoptosis rate,IL-6,TNF-α,ROS and MDA in the HG group were significantly increased(P<0.05),while the levels of TSC1 mRNA,cell viability and SOD were significantly decreased(P<0.05).Compared with the HG+si-NC group,the levels of lnRNA HOTAIR,ap-optosis rate,IL-6,TNF-α,ROS and MDA in the HG+si-HOTAIR group significantly decreased(P<0.05),the levels of TSC1 mRNA,cell viability and SOD were significant increased(P<0.05).Compared with the HG+si-HOTAIR+sh-NC group,the levels of apoptosis rate,IL-6,TNF-α,ROS and MDA in the HG+si-HOTAIR+sh-TSC1 group were significantly increased(P<0.05),the levels of TSC1 mRNA,cell viability and SOD were significantly decreased(P<0.05).Conclusion Silencing lnRNA HOTAIR can target TSC1 to regulate the activity,apoptosis rate,inflammatory level and oxidative stress levels of podocyte injury in DN,thereby alleviating podocyte damage in DN.

Diabetic retinopathy(DR)is a prevalent microvascular complication of diabetes and a leading cause of vision loss globally.Although anti-vascular endothelial growth factor(anti-VEGF)therapies remain the clinical mainstay, a significant proportion of patients exhibit suboptimal responses, highlighting the urgent need for novel therapeutic targets. Calcitonin gene-related peptide(CGRP), a multifunctional neuropeptide, is gaining attention due to its roles in vascular regulation, neuroprotection, and immunomodulation. This review summarizes the biological characteristics of CGRP and its receptor-mediated signaling, and explores emerging evidence of CGRP's involvement in DR through its vasodilatory effects and regulatory effect on neurodegenerative disorders and release of inflammatory cytokines. Furthermore, the therapeutic potential of targeting the CGRP pathway in DR is evaluated, especially in cases unresponsive to VEGF inhibition. Despite currently the lack of CGRP-targeted drugs applied for DR, the peptide demonstrates efficacy and safety in other diseases, such as migraine, suggests promising translational opportunities. However, CGRP may play a dual role in different pathological stages of DR, thus its treatment strategy needs to be considered precisely. Future research elucidating the precise mechanisms of CGRP in DR may pave the way for innovative intervention strategies.

Objective: To analyze the correlation between refractive errors and physical development indicators among primary school students aged 6 to 9, so as to provide a scientific basis for the development of effective prevention and control measures. Methods: A stratified cluster random sampling method was used to recruit 2 833 elementary school students aged 6 to 9 from Guangdong Province for vision screening, ocular biometry, and physical examinations in Octorber, 2020. The Chi square test, t-test, and ANOVA were employed to compare myopia rates and indicator values across different groups. Multiple linear regression models were used to analyze the correlations between height, weight, and body mass index (BMI) with refractive development indicators. Results: The screening myopia rate among primary school students aged 6 to 9 was 16.7%, and the myopia rate increased with age ( χ 2= 51.58 , P <0.01). The height and weight of the myopic group [(126.96±7.41)cm, (26.59±6.45)kg] were higher than those of the non myopic group [(124.76±7.77)cm, (25.42±5.87)kg] ( t =5.84, 3.65, P <0.01). The mean values of spherical equivalent (SE), axial length (AL), anterior chamber depth (ACD), and AL/corneal curvature radius (CR) ratio for students aged 6 to 9 were (-0.17±1.04)D, (22.96±0.78)mm, (3.38±0.24)mm, and (2.95±0.08), respectively, with statistically significant differences across different age and myopia severity groups ( t =37.08, 119.20, 41.54, 133.60; 935.30, 184.10, 73.95, 498.50, P < 0.01). After adjusting for gender, age, and residence, the multiple linear regression model showed that height was positively correlated with AL and CR, weight was positively correlated with ACD, and BMI was positively correlated with AL and ACD ( β = 0.191 , 0.070, 0.035, 0.013, 0.007, P <0.05). When stratified by myopia status, results for the non-myopic group were similar to the overall results, whereas in the myopic group, the correlations between height, BMI, and AL were not statistically significant ( P > 0.05). Conclusions Among primary school students aged 6 to 9, height and BMI are positively correlated with AL in the non myopic group but no similar correlation is observed in the myopic group, indicating that factors other than physical development, such as environmental and behavioral factors, should be considered for their impact on refractive development.
