BACKGROUND:Epidemiological studies indicate that individuals with neurodegenerative diseases exhibit a comparatively lower risk of developing the majority of cancers.Although the precise mechanisms underlying this inverse correlation remain unclear,it is noteworthy that aberrant glucose metabolism,a pathological factor common to both conditions,may significantly contribute to this association.OBJECTIVE:To review the potential relationship between cancers and neurodegenerative diseases in glucose metabolism.METHODS:PubMed was searched for relevant literature using the search terms of"cancer,neurodegenerative diseases,Alzheimer's disease,Parkinson's disease,metabolic reprogramming,glucose metabolism,aerobic glycolysis,neuroprotection,aging,"and 136 articles were finally included for analysis.RESULTS AND CONCLUSION:Cancer and neurodegenerative diseases exhibit a profound pathological correlation at the level of glucose metabolism imbalance associated with aging.Cancer cells promote uncontrolled proliferation,invasion,and metastasis through the persistent activation of aerobic glycolysis,whereas neurodegenerative diseases are characterized by a reduction in aerobic glycolysis.Restoring aerobic glycolysis may confer neuroprotective effects and delay disease progression.The key nodes of glucose metabolism demonstrate a bidirectional regulatory pattern:metabolic regulators,which are significantly upregulated or aberrantly activated in cancer,are inhibited or functionally inactivated in neurodegenerative diseases.Mitochondria play a crucial role in mediating the aging process through the regulation of reactive oxygen species homeostasis and mitochondrial autophagy.They establish regulatory networks that connect cancer and neurodegenerative diseases,and maintaining their functional homeostasis is of paramount importance for disease prevention and treatment.

Objective To investigate the impact of Astragaloside-IV (AS-IV) on the progression of myocardial infarction (MI) through macrophage-dependent mechanisms by regulating Snail1 lactylation and acetylation, as well as the transforming growth factor β (TGF-β) pathway. Methods Oxygen glucose deprivation (OGD) was used to establish an in vitro myocardial ischemia model in rat cardiomyocytes (H9c2), which were then treated with AS-IV. Cell viability was assessed using CCK-8, apoptosis was evaluated by flow cytometry, and LDH levels were measured to assess cellular damage. RAW246.7 cells were treated with LPS, and lactate levels in the supernatant were measured using ELISA, while expression of macrophage phenotype markers was evaluated using Western blot. RAW246.7 cell-conditioned medium (CM) was co-cultured with H9c2 cells to assess the protective effects of AS-IV on macrophage CM-mediated H9c2 damage. RAW246.7 cells were induced to differentiate into M1-like macrophages using LPS (100 ng/mL) + IFN-γ (20 ng/mL), and Snail1 was overexpressed in M1 macrophages. Transfected M1 macrophage CM was co-cultured with H9c2 cells to validate the mechanisms of AS-IV in MI. An MI rat model was established by ligation of the left anterior descending coronary artery (LAD), and was treated with AS-IV. Cardiac function, myocardial cell apoptosis, and cardiac tissue pathology were studied using echocardiography, TUNEL, and HE staining, respectively. Results Compared to the OGD group, AS-IV treatment promoted cell viability, reduced apoptosis and decreased LDH release. LPS upregulated lactate levels in the supernatant of RAW246.7 cell cultures and induced polarization of RAW246.7 cells to the M1 phenotype. AS-IV attenuated the damaging effects of RAW246.7 cell CM on H9c2 cells . Overexpression of Snail1 in M1 macrophages weakened the protective effects of AS-IV on H9c2 cells . In vivo study, results showed that, compared to the MI group, AS-IV treatment reduced lactate levels in the hearts of MI rats, improved cardiac function and myocardial injury and attenuated myocardial cell apoptosis. Conclusion AS-IV inhibits TGF-β pathway activation through the suppression of Snail1 lactylation and acetylation in a macrophage-dependent manner, thereby mitigating myocardial cell damage following MI.

Objective:To evaluate the efficacy of preoperative prediction of regional lymph node (RLN) metastasis in renal cell carcinoma (RCC) using a machine learning model based on habitat imaging radiomics from renal MRI.Methods:This cross-sectional study retrospectively analyzed 220 patients with RCC who underwent nephrectomy and RLN dissection at four medical centers of Chinese PLA General Hospital from January 2010 to August 2023. The cohort included 65 patients with RLN metastasis and 155 without. A stratified random sampling method was used to divide 175 patients from the first medical center into a training set ( n=140) and an internal test set ( n=35) in an 8∶2 ratio, while 45 patients from the third, fourth, and fifth medical centers constituted the external test set. The primary RCC lesions were categorized into 15 habitat subregions based on corticomedullary-phase enhancement and T 2WI signal intensity on MRI, and the volume fractions of different subregions were analyzed. In the training cohort, radiomics features derived from the habitat subregions were used to construct a radiomics model employing various machine learning algorithms, including extremely random trees (ET), gradient boosting decision trees (GBDT), random forest (RF), and support vector machine (SVM). The optimal model was selected and combined with RLN short-axis diameter to develop a combined model. The efficacy of each model in predicting RLN metastasis was evaluated using the receiver operating characteristic (ROC) curve. Results:The volume fraction of hyper-enhanced hyper-intense regions in the non-metastatic group was significantly higher than that in the metastatic group (0.05±0.09 vs. 0.02±0.03; t=3.00, P=0.003). Among the machine learning models constructed using 15 optimal habitat radiomics features, the SVM model demonstrated the best performance, with area under the ROC curve (AUC) values of 0.85 (95% CI 0.72-0.98) in the internal test set and 0.82 (95% CI 0.67-0.98) in the external test set, surpassing those of the ET, GBDT, and RF models. The combined model, integrating the SVM model with RLN short-axis diameter, achieved AUC values of 0.94 (95% CI 0.85-1.00) in the internal test set and 0.89 (95% CI 0.78-1.00) in the external test set, with RLN short-axis diameter contributing AUC values of 0.81 (95% CI 0.66-0.96) and 0.81 (95% CI 0.68-0.94), respectively. The diagnostic sensitivity of the combined model was 91.7% in the internal test set and 85.7% in the external test set, with specificities of 78.3% and 67.7%, respectively. Conclusion:The combined model based on MRI habitat imaging radiomics and RLN short-axis diameter demonstrates excellent preoperative assessment capability for RLN metastasis in RCC.

Objective:To investigate the molecular mechanism of miR-886-5p targeting BCL-2-associated X protein (BAX) to inhibit the proliferation, migration, and invasion of liver cancer cells.Methods:mRNA expression data of HCC patients were obtained from the Starbase database, including 370 liver cancer samples and 50 normal liver tissue samples adjacent to the cancer. Analyze the expression of miR-886-5p in the previously obtained data and investigate the relationship between miR-886-5p and BAX in liver cancer samples. After transfection of the corresponding plasmids into Huh7 and HepG2 cells, the following groups were established. Analyze the interaction between miR-886-5p and BAX in vitro, detect the protein expression by Western blotting, and verify the targeting relationship between the two by dual luciferase reporter gene assay.Results:Starbase database analysis found that the standardized expression level of miR-886-5p in 370 liver cancer samples was lower than that in normal liver tissue samples (0.12±0.07 vs. 0.73±0.27, t=-15.71, P<0.001), and the expression level of miR-886-5p was positively correlated with the expression level of BAX ( r=0.152, P=0.003). qRT-PCR analysis showed that the expression level of miR-886-5p in HL-7702 cells was higher than that in Huh7 (4.57±0.06 vs. 1.61±0.40, t=32.48) and HepG2 (4.57±0.06 vs. 1.03±0.13, t=143.9), and the expression level of BAX in HL-7702 cells was higher than that in Huh7 (4.01±0.12 vs. 1.28±0.09, t=82.20) and HepG2 (4.01±0.12 vs. 1.30±0.11, t=80.76), the differences were statistically significant (all P<0.001). The proliferation, migration, and invasion abilities of Huh7 and HepG2 cells decreased after transfection with miR-886-5p mimics, while the expression levels of BAX at the mRNA and protein levels increased. However, after inhibiting the expression of miR-886-5p, the above indicators of cells were the opposite, and the dif-ferences were statistically significant (all P<0.05). The viability, EdU positivity rate, cell migration rate, and number of transmembrane cells in the miR-886-5p+ BAX group were lower than those in the BAX group, and the relative expression levels of miR-886-5p, BAX mRNA, and BAX protein were higher than those in the BAX group. However, the above indicators in the Sponge+ BAX group showed opposite trends, and all differences were statistically significant (all P<0.05). There was a targeted binding site between miR-886-5p and BAX. Conclusion:Both miR-886-5p and BAX are downregulated in liver cancer, and miR-886-5p inhibits the proliferation, migration, and invasion of liver cancer cells by targeting BAX.

Objective:To investigate the clinical efficacy of ankle perturbation training(APT)on dynamic balance and gait characteristics in hemiplegic stroke patients.Method:From August 2023 to May 2024,32 hemiplegic stroke patients who met the inclusion criteria were recruited from the Department of Rehabilitation Medicine of the Affiliated Hospital of Binzhou Medical univer-sity.Participants were randomly assigned to two groups:the control group received conventional rehabilitation training(CRT)supplemented with ankle functional training(AFT)for 30 minutes per day,5 days per week,for 4 weeks,the experimental group underwent APT in addition to the control group regimen.Dynamic bal-ance and gait parameters,including spatio-temporal gait parameters,center of pressure(COP),and movement trajectory were collected by Berg balance scale(BBS),time up and go test(TUGT)and Zebris plantar pres-sure plate before and after 4 weeks of treatment,respectively.COP was used to assess the dynamic balance.Result:Before treatment,there was no significant difference between the two groups(P>0.05).After 4 weeks of treatment,the dynamic balance and related gait parameters in both group were significantly improved in BBS score,TUGT,gait line length on the affected side,single-support line length on the affected side and medi-al-lateral displacement were significantly different between the groups(P<0.05).However,no significant differ-ences were found between the groups for step length,stride length,stride speed,or stride frequency(P>0.05).Conclusion:Ankle perturbation training can effectively improve balance function and walking ability in hemi-plegic patients with stroke,and is superior to ankle functional training in improving balance function parame-ters.

Purpose To evaluate the differential diagnostic value of 5.0T MRI susceptibility-weighted imaging(SWI)in hepatocellular carcinoma(HCC)and mass-forming intrahepatic cholangiocarcinoma(MICC).Materials and Methods A total of 56 patients with HCC and 36 patients with MICC confirmed by pathology from March 2023 to November 2024 in Anhui Provincial Hospital were retrospectively enrolled.Two radiologists independently analyzed three features of the lesions,including the low-signal rims around the lesion,hemorrhage within the lesion,and the relationship between lesions and adjacent vessels,on the SWI sequence between the two groups,respectively,via inter-rater consistency analysis.These above features between the two groups were compared and contrasted them with those obtained from conventional MR plain and enhanced scans,respectively.For intralesional hemorrhages,the diagnostic value was quantified by calculating the internal tissue susceptibility signal.Results The radiologists showed good consistency in the low-signal rims,intratumoral hemorrhage as well as the relationship between the lesion and the blood vessel on the SWI in the HCC group and the MICC group(Kappa=0.802-0.929,all P<0.001).Compared with conventional MR plain,SWI significantly enhanced the detection rates of perilesional low-signal rims and intratumoral hemorrhage(χ2=89.409,46.210,both P<0.001).These findings were more prevalent in HCC patients.The internal tissue susceptibility signal grading showed that HCC predominantly exhibited grade 3,whereas MICC predominantly exhibited grade 1,with statistically significant differences(Z=-4.059,P<0.05).Additionally,compared with enhanced MRI,SWI demonstrated higher accuracy in diagnosing the relationship between lesions and blood vessels in both groups;however,these differences were not statistically significant(χ2=0.275,0.247,P=0.871,0.619).In the HCC group,the relationship between tumors and blood vessels was primarily characterized by compression and tumor thrombus formation,while in the MICC group,it was predominantly marked by invasive changes,including vessel encasement,stenosis or occlusion,with a statistically significant difference between the two groups(Z=-6.809,P<0.001).Conclusion SWI sequence of 5.0T MRI provides clear visualization of the internal and peripheral structures of HCC and MICC.It can accurately delineate the relationship between lesions and blood vessels without the need for contrast agents,offering significant clinical utility in differentiating these two conditions.

Objective To evaluates the effects of cross-balance training on knee function,dynamic balance,and rectus femoris(RF)activation in patients after anterior cruciate ligament reconstruction(ACLR).Methods Forty ACLR patients at 5th-6th week after operation were randomly divided into experimental group and control group.The experimental group received the cross-balance training on the basis of standard rehabilitation,while the control group received only standard rehabilitation.Knee function was assessed with the Lysholm score,dynamic balance,and root mean square(RMS)of RF surface electromyography.The correlation between RMS and dynamic balance was also examined.Results After intervention,the Lysholm score of the experimental group was significantly higher than that of the control group(P<0.01).Regarding balance function,both the gait line length and single support line length of the experimental group were significantly greater than those of the control group(P<0.01).Conversely,the mediolateral displacement of the experimental group was significantly lower than that of the control group(P<0.01).Furthermore,the RF RMS of the experimental group was significantly larger than that of the control group(P<0.01).The RF RMS was positively correlated with the gait line length and single support line length,whereas it was negatively correlated with the mediolateral displacement(P<0.05).Conclusions Cross-balance training significantly enhances knee function,dynamic balance,and RF activation in post-ACLR patients,supports the theory of cross-education.Cross-balance training has certain application values in ACL postoperative rehabilitation.
