Lung cancer remains one of the most prevalent and deadly malignancies worldwide, with persistently low five-year survival rates. This poor prognosis is primarily attributed to challenges such as difficulties in early diagnosis, high tumor heterogeneity, and strong therapeutic resistance. Although recent advances in targeted therapies and immune checkpoint inhibitors have significantly improved the prognosis of some patients, the majority still encounter primary or secondary resistance. Galectin-3, a multifunctional glycan-binding protein, is constitutively expressed in pulmonary tissues. Its expression encompasses bronchial and alveolar epithelial cells, the pulmonary vasculature, and resident immune cells. Galectin-3 plays a central role in lung cancer progression by regulating tumor cell proliferation, immune evasion, and angiogenesis. The complex immunosuppressive mechanisms within the tumor microenvironment not only facilitate tumor growth and metastasis but also partially limit the efficacy of cancer immunotherapies. Overcoming these barriers requires the exploration of novel regulatory targets to break through therapeutic bottlenecks. This review systematically elucidates the mechanisms by which galectin-3 interacts with immune cells (e.g., T cells, macrophages) in the tumor microenvironment and evaluates its potential as a therapeutic target, including inhibitor development and combination immunotherapy strategies. The findings aim to provide a theoretical foundation for advancing galectin-3 as a novel therapeutic target in lung cancer and offer new perspectives for overcoming current immunotherapy resistance.

Acute kidney injury (AKI), a life-threatening clinical syndrome, lacks effective therapeutic interventions beyond supportive care such as hemodialysis and kidney transplantation. Pathologically, excessive reactive oxygen species -mediated oxidative stress is recognized as a pivotal contributor to AKI progression, positioning reactive oxygen species scavenging as a critical therapeutic target. Emerging nanozymes, nanomaterials with enzyme-mimetic activities, have shown promise in addressing AKI by targeting renal oxidative stress. The article mainly reviewed the content of classification of nanozymes, research findings on nanozymes in treating AKI along with discussions on their mechanisms of action, as well as the current challenges and existing issues in nanozymes-based AKI therapy, to provide enhanced research perspectives for advancing nanozyme applications in the prevention and treatment of AKI.

Objective:To simulate and compare the impact of scar contraction force on maxillary alveolar bone displacement after cleft palate surgery in different regions of the palate.Methods:The same scar contraction force was applied to the grouping hard pal-ate area on the original finite element model of the maxilla with cleft palate,and calculations were performed in ANSYS 17.0.Divid-ed into four groups based on the applied force area:anterior half(group 1),posterior half(group 2),lateral half(group 3),and me-dial half(group 4).Nodes in the alveolar bone of the cleft and non-cleft sides were selected as observation points.The three-dimen-sional displacement of observation points was recorded and compared between groups.Results:The displacement of group 1＞group 3,4＞group 2(P＜0.01).Conclusion:Scars from different parts of the hard palate can lead to a decrease in the length,width,and height of the maxillary alveolar bone.Among them,the anterior scar has the most severe impact,followed by the medial and lateral scars,and the posterior scar has the smallest impact.

Objective:To construct an early prediction model for post cardiopulmonary resuscitation-acute kidney injury (PCPR-AKI) by machine learning and provide a basis for early identification of acute kidney injury (AKI) high-risk patients and accurate treatment.Methods:It was a single-center retrospective study. The clinical data of patients admitted to Tianjin Medical University General Hospital after cardiopulmonary resuscitation following cardiac arrest from January 1, 2016 to October 31, 2023 were collected. The end-point event of the study was defined as AKI occurring within 48 hours after cardiopulmonary resuscitation. The patients were divided into AKI group and non-AKI group according to the AKI diagnostic criteria, and the differences of baseline clinical data between the two groups were compared. The patients who met the inclusion criteria were randomly (using the train_test_split function, set the random seeds to 1, 2, and 3) divided into training and validation sets at a ratio of 7∶3. Random forest (RF), support vector machine, decision tree, extreme gradient boosting and light gradient boosting machine algorithm were used to develop the early prediction model of PCPR-AKI. The receiver-operating characteristic curve and decision curve analysis were used to evaluate the performance and clinical practicality of the predictive models, and the importance of variables in the optimal model was screened and ranked.Results:A total of 547 patients were enrolled, with age of 66 (59, 70) years old and 282 males (51.6%). There were 238 patients (43.5%) having incidence of AKI within 48 hours after cardiopulmonary resuscitation. In the AKI group, 182 patients (76.5%) were in stage 1, 47 patients (19.7%) were in stage 2, and 9 patients (3.8%) were in stage 3. There were statistically significant differences in the age, time to reach resuscitation of spontaneous circulation, time from cardiac arrest to starting cardiopulmonary resuscitation, proportion of initial defibrillation rhythm, proportion of electric defibrillation, proportion of mechanical ventilation, adrenaline dosage, sodium bicarbonate dosage, proportion of coronary heart disease, proportion of hypertension, proportion of diabetes, serum creatinine, blood urea nitrogen, blood lactic acid, blood potassium, brain natriuretic peptide, troponin, D-dimer, neuron specific enolase, and 24 hours urine volume after cardiopulmonary resuscitation between AKI group and non-AKI group (all P<0.05). Among the five machine learning algorithms, RF model achieved the best performance and clinical practicality, with area under the curve of 0.875, sensitivity of 0.863, specificity of 0.956, and accuracy rate of 90.7%. In the variable importance ranking of RF model, the top 10 variables were as follows: time to reach resuscitation of spontaneous circulation, time from cardiac arrest to starting cardiopulmonary resuscitation, initial defibrillable rhythm, serum creatinine, mechanical ventilation, blood lactate acid, adrenaline dosage, brain natriuretic peptide, D-dimer and age. Conclusions:An early predictive model for PCPR-AKI is successfully constructed based on machine learning. RF model has the best predictive performance. According to the importance of the variables, it can provide clinical strategies for early identification and precise intervention for PCPR-AKI.

AIM: To evaluate the safety and efficacy of ultrasonic cycloplasty(UCP)combined with anti-vascular endothelial growth factor(VEGF)+ panretinal photocoagulation(PRP)in the treatment of advanced neovascular glaucoma(NVG).METHODS: Retrospective study. A total of 45 patients(45 eyes)with advanced NVG who received surgery in our hospital from August 2020 to September 2022 were collected and divided into UCP+ anti-VEGF +PRP group(16 patients, 16 eyes), transscleral cyclophotocoagulation(TCP)+anti-VEGF+PRP group(20 patients, 20 eyes), UCP alone group(9 patients, 9 eyes). The intraocular pressure, pain scores, postoperative medication, effective rate, total success rate and the incidence of complications of the patients in the three groups were compared before surgery and at 1 d, 1 wk, 1 and 3 mo after surgery.RESULTS: There was no significant difference in preoperative intraocular pressure, pain scores and preoperative medication of patients in the three groups(all P>0.05). While there were statistical significance in the intraocular pressure and pain scores at 1 d, 1 wk, 1 and 3 mo after surgery(all P<0.01). The intraocular pressure of the UCP alone group(31.78±10.23 mmHg)was found to be higher than that of both the UCP+ anti-VEGF +PRP group(19.44±8.23 mmHg)and the TCP+ anti-VEGF +PRP group(20.80±10.27 mmHg)at 1 mo postoperatively(all P<0.017). The pain score of the TCP+ anti-VEGF +PRP group at 1 d and 1 wk postoperatively was higher than both the UCP+ anti-VEGF +PRP group and the UCP alone group(all P<0.017). The effective rates of UCP+ anti-VEGF +PRP group, TCP+ anti-VEGF +PRP group and UCP alone group were 81%(13/16), 75%(15/20)and 67%(6/9), respectively,(P=0.675), and the success rates were 69%(11/16), 50%(10/20), and 0(0/9), respectively(P=0.003). There was no significant difference in complications of patients in the three groups(P>0.05).CONCLUSION: UCP combined with anti-VEGF +PRP and TCP combined with anti-VEGF +PRP showed comparable efficacy in reducing intraocular pressure in advanced NVG. UCP combined with anti-VEGF+PRP was more effective in relieving pain and with no serious complications in advanced NVG. UCP alone can effectively control intraocular pressure and alleviate the pain of patients in the early postoperative period, but long-term control still requires anti-VEGF+PRP.

Objective:To study the effect of Compound Duzhong Jiangu Granules on joint function, quality of life and inflammatory factors in patients with Kashin-Beck disease.Methods:By group design, 135 patients with Kashin-Beck disease in Chongxin County, Pingliang City, Gansu Province, were selected and divided into intervention group (100 cases treated with Compound Duzhong Jiangu Granules, 12 g/bag, 1 bag/time, 3 times/day, treatment for 1 month) and control group (35 cases treated with ibuprofen, 0.3 g/capsule, 1 capsule/time, 2 times/day, treatment for 2 weeks) according to the randomized, single-blind principle. The changes of joint dysfunction index score, joint function improvement rate, total scores of Kashin-Beck disease quality of life (KBDQOL) and scores of each dimension were analyzed before treatment, 1 month and 3 months after treatment. The serum levels of interleukin-6 (IL-6), nuclear factor κB (NFκB)-p65, inducible nitric oxide synthase (NOS2), nitric oxide (NO), and prostaglandin E2 (PGE2) were detected by enzyme-linked immunosorbent assay before treatment and 1 month after treatment.Results:The total scores of joint dysfunction index of the intervention group and the control group 1 month after treatment and 3 months after treatment were lower than those before treatment, but 3 months after treatment was higher than 1 month after treatment ( P < 0.001). One month after treatment, the total effective rates of joint function improvement in the intervention group and the control group were 68.00% (68/100) and 54.55% (18/33), respectively; 3 months after treatment, the total effective rates of the intervention group and the control group were 36.00% (36/100) and 39.39%(13/33), respectively. The total scores and scores of each dimension of KBDQOL were not significant for the main effect of the group ( P > 0.05), but significant for the main effect at the time point ( P < 0.05), and there was no interactive effect ( P > 0.05). There were significant differences in the scores of social support and mental status dimensions in the intervention group at different time points ( P < 0.001). And in the intervention group, the total score, the scores of physical function, activity limitation, economy and overall health dimensions were statistically significant between before treatment and 1 month after treatment, 1 month after treatment and 3 months after treatment( P < 0.05); however, there was no significant difference between before treatment and 3 months after treatment ( P > 0.05). One month after treatment, the serum PGE2 levels of both groups were decreased ( P < 0.05), and there was no difference in other inflammatory factors at different groups and time points ( P > 0.05). Conclusion:Compound Duzhong Jiangu Granules can effectively inhibit the inflammatory reaction of patients with Kashin-Beck disease, promote the improvement of joint function and improve the quality of life in various aspects.
