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.

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 assess the effects of various leisure hobbies on the ability of daily living(ADL)and the quality of life among older adults in China.Methods:A cross-sectional study was conducted using data from the 4th Chinese Urban and Rural Elderly Living Conditions Sample Survey.We categorized community recreation hobbies into two types: dynamic hobbies, which include walking, playing ball games, dancing, and other physical activities, and static hobbies, which encompass activities that do not require physical exertion, such as reading, watching TV, and drawing.The EuroQol five-dimension scale(EQ-5D)-3L was employed to evaluate the quality of life.Older adults who maintained either dynamic or static hobbies for three consecutive years from 2017 to 2019 were initially screened.The relationship between different types of leisure hobbies and ADL scores, as well as quality of life at various time points, was analyzed using repeated-measures ANOVA.Subsequently, propensity scores were matched based on gender, age, ethnicity, marital status, literacy, and chronic diseases, and five machine learning algorithms were utilized to identify the optimal model for predicting fully independent ADL and EQ-5D effect values.Based on the optimal predictive model, we conducted Shapley Additive Explanations(SHAP)and global analysis.Results:The total number of older adults who participated in the survey over the three consecutive years from 2017 to 2019 was 4 912.Among these, 2 594 individuals maintained the same hobby habits throughout this period, comprising 1 362 males and 1 232 females, with an average age of(70.81±6.71)years.Statistically significant differences in ADL scores and EQ-5D scores were observed between the dynamic and static leisure hobby groups(all P<0.05)across various time points, hobby group classifications, and interaction levels.Older adults engaged in dynamic hobbies exhibited superior ADL functioning and higher EQ-5D scores in comparison to those in the static hobby group, with these differences remaining statistically significant following propensity score matching(all P<0.05).In predicting full ADL independence, the SHAP value for dynamic hobbies ranked second, while for predicting an EQ-5D weighted value of 1, the SHAP value for dynamic hobbies ranked ninth.Overall, the type of dynamic hobby demonstrated a positive trend in its effect on the ability to perform daily activities independently and in achieving an EQ-5D weighted value of 1. Conclusions:In comparison to static hobbies, Chinese older adults who engage in dynamic hobbies exhibit improved daily mobility and a higher quality of life.Furthermore, dynamic hobbies positively influence the capacity for full independence in daily activities, as evidenced by an EQ-5D weighted value of 1.

Objective:To investigate the multimorbidity of myopia and obesity, as well as myopia and malnutrition, among children and adolescents aged 7-18 in Guangdong Province and analyze their epidemiological characteristics and related factors.Methods:A stratified random cluster sampling method was used to select 274 939 children and adolescents aged 7-18 from 21 cities in Guangdong Province in 2023. Physical examination information such as height, weight, distance vision, and diopter, as well as questionnaire survey information on dietary behavior, physical activity, screen behavior, sleep time, etc., were collected to analyze the current status and trends of multimorbidity between myopia and obesity, myopia and malnutrition. The multivariate logistic regression model was used to analyze the related factors of multimorbidity.Results:The multimorbidity rates of myopia and obesity, myopia and malnutrition in children and adolescents aged 7-18 in Guangdong Province in 2023 were 4.43% and 6.40%, respectively. The multimorbidity rates for males were 5.44% and 6.88%, respectively, which were higher than those for females, about 3.31% and 5.88% (both P<0.001). The multimorbidity rates of urban students were 5.03% and 6.73%, respectively, which were higher than those of county students at 4.03% and 6.18% (both P<0.001). The multimorbidity rates of myopia and obesity, myopia and malnutrition increased with the increase of academic stage (all P<0.001). The multimorbidity rates of myopia and obesity, as well as myopia and malnutrition, fluctuated with age, with the first decrease occurring at the age of 12. The multivariate logistic regression analysis showed that compared to children and adolescents aged 7-18 who had daily after-school tutoring <2 hours, daily screen time <2 hours, did not consume sugary drinks every day, sleep time that could meet health requirements daily, and exercised≥60 minutes of moderate-to vigorous-physical activity ≥60 minutes for at least 3 days per week, those who had daily after-school tutoring ≥2 hours ( OR=1.18, 95% CI: 1.11-1.26), daily screen time ≥2 hours ( OR=1.09, 95% CI: 1.02-1.16), consumed sugary drinks every day ( OR=1.20, 95% CI: 1.11-1.30), daily sleep time that could not meet the health requirements ( OR=1.16, 95% CI: 1.09-1.23), and no exercise per week ( OR=1.09, 95% CI: 1.01-1.18) had a higher risk of multimorbidity of myopia and obesity. Compared to children and adolescents who exercised≥60 minutes of moderate-to vigorous-physical activity ≥60 minutes for at least 3 days per week, those who exercised <3 days per week ( OR=1.20, 95% CI: 1.17-1.34) had a higher risk of multimorbidity of myopia and malnutrition. Conclusion:The multimorbidity rates of myopia and obesity, as well as myopia and malnutrition, in children and adolescents aged 7-18 in Guangdong Province are relatively low and fluctuate with age. Physical activity, screen time, consumption of sugary drinks, and sleep time may be associated with these multimorbidities.

Objective To analyze the effectiveness and safety of endoscopic thyroidectomy through the areola approach for thyroid carcinoma.Methods From January 2020 to June 2022,100 patients with thyroid carcinoma were grouped into group A(n=50,endoscopic thyroidectomy via axillary approach)and group B(n=50,endoscopic thyroidectomy via areola approach)using a random number table method.The intraoperative and postoperative indicators,aesthetic effects,complications,and survival rate of the two groups were compared.Results The surgical time of group B was longer than that of group A,the intraoperative bleeding and postoperative drainage volume were more than those of group A,the differences were statistically significant(P<0.05);There was no statistically obvious difference in the number of lymph node dissections,postoperative extubation time,length of hospital stay,Vancouver scar scale(VSS)score,survival rate,and total incidence of complications between the two grousps(P>0.05).Conclusion Endoscopic thyroidectomy through the areola approach for thyroid carcinoma is similar to endoscopic thyroidectomy through the axillary approach in terms of the number of lymph node dissections,postoperative extubation time,hospital stay,aesthetic effect,complications,and survival rate,but the operation time is longer,the intraoperative blood loss is more,and the postoperative drainage is also more.Clinically,the appropriate surgical approach can be selected according to the actual situation.
