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 30-day mortality risk factors in elderly patients with heart failure with reduced ejection fraction (HFrEF) after isolated coronary artery bypass grafting (CABG) and to construct a nomogram for predicting mortality risk. Methods A retrospective analysis of elderly (≥70 years) HFrEF patients undergoing isolated CABG at Tianjin Chest Hospital from 2010 to 2024 was performed. Simple random sampling in R software was used to divide the dataset into training and validation sets in a 7 : 3 ratio. The training set was further divided into survivors and non-survivors. Univariate logistic regression was performed to identify differences between groups, followed by multivariate logistic regression to select independent risk factors for death and to establish a death-risk nomogram, which underwent internal validation. The predictive value of the nomogram was assessed by plotting receiver operating characteristic (ROC) curves, calibration curves, and decision-curve analyses for both the training and validation sets. Results A total of 656 patients were included. The training set consisted of 458 patients (survivors 418, deaths 40); the validation set consisted of 198 patients (survivors 180, deaths 18). In the training set, univariate analysis showed significant differences between survivors and deaths for creatinine (Cr) level, brain natriuretic peptide (BNP), maximum Cr, intra-aortic balloon pump (IABP) use, assisted ventilation, reintubation, hyperlactatemia, low cardiac output syndrome, and renal failure (P<0.05). After multivariable logistic regression, five independent risk factors were identified: IABP use (OR=3.391, 95%CI 1.065-11.044, P=0.038), reintubation (OR=15.991, 95%CI 4.269-67.394, P<0.001), hyperlactatemia (OR=8.171, 95%CI 2.057-46.089, P=0.007), Cr (OR=4.330, 95%CI 0.997-6.022, P=0.024), and BNP (OR=1.603, 95%CI 1.000-2.000, P=0.010). Accordingly, a nomogram predicting mortality risk was constructed. The ROC and calibration analyses indicated good predictive value: area under the curve (AUC) in the training set was 0.898 (95%CI 0.831-0.966) and in the validation set was 0.912 (95%CI 0.805-1.000). Calibration and decision-curve analyses showed good agreement and clinical utility. Conclusion The nomogram incorporating IABP use, reintubation, hyperlactatemia, creatinine, and BNP provides good predictive value for 30-day mortality after CABG in elderly patients with HFrEF and demonstrates potential clinical utility.

Enterotoxigenic Escherichia coli(ETEC)is the main cause of diarrhea in piglets,which seriously threatens the development of animal husbandry.In order to effectively prevent and con-trol piglet diarrhea,the neutralizing epitopes of the screened K88(FTDYEGASVELRKPDGGT-NK),K99(NVGNGSGGANIN),987P(LAAPAENNTSQAN),F41(VMAADWTEGQPGDII)and F18(PPNAQTYPLSSGDLK)ETEC adhesins were assembled to construct the multi-epitope fusion antigen(MEFA),whose immunogenicity was verified by in silico simulations and in vitro.The computer simulation results showed that MEFA has excellent physicochemical properties and reasonable prediction results of secondary and tertiary structures and exhibits strong interaction force when docking with toll-like receptor 3,and the kinetic simulation shows that it can be stably presented.In vitro validation results showed that anti-K88,K99,987P,F18 and F41 IgY could spe-cifically recognize MEFA proteins.After immunization of laying hens with MEFA,the titers of IgY antibodies against the five ETEC were higher than those of non-specific IgY.In addition,specific anti-MEFA IgY significantly inhibited the adhesion of K88,K99,987P,F41 and F18 ETEC strains to piglet intestinal IPEC-J2 cell lines.These results indicate that MEFA has strong immunogenicity and can be used as an ideal vaccine candidate for the prevention of K88,K99,987P,F41 and F18 ETEC infection,and provide reference and technical support for the development of multivalent broad-spectrum ETEC vaccine candidates.

The "brain electric field" therapy is a novel electroacupuncture method created by Professor GAO Weibin to treat cerebral infarction in the recovery period. This therapy is suitable for the treatment of motor disorders, sensory disorders, cognitive disorders, hemianopsia and bulbar paralysis during the recovery period of cerebral infarction. Based on the different symptoms, the corresponding brain functional areas are selected, supplemented with Taiyang 2, Tunyan 2, Tiyan, Gongxue and Xiatianzhu. These points are attached to electric acupuncture apparatus, and stimulated with dense wave, at frequency of 50 Hz and tolerable intensity. This therapy presents a remarkable effect on cerebral infarction in the recovery period, providing the new approach to the treatment of this disease.

Objective:To construct and evaluate a screening and diagnostic system based on color fundus images and artificial intelligence (AI)-assisted screening for optic neuritis (ON) and non-arteritic anterior ischemic optic neuropathy (NAION).Methods:A diagnostic test study. From 2016 to 2020, 178 cases 267 eyes of NAION patients (NAION group) and 204 cases 346 eyes of ON patients (ON group) were examined and diagnosed in Zhongshan Ophthalmic Center of Sun Yat-sen University; 513 healthy individuals of 1 160 eyes (the normal control group) with normal fundus by visual acuity, intraocular pressure and optical coherence tomography examination were collected from 2018 to 2020. All 2 909 color fundus images were as the data set of the screening and diagnosis system, including 730, 805, and 1 374 images for the NAION group, ON group, and normal control group, respectively. The correctly labeled color fundus images were used as input data, and the EfficientNet-B0 algorithm was selected for model training and validation. Finally, three systems for screening abnormal optic discs, ON, and NAION were constructed. The subject operating characteristic (ROC) curve, area under the ROC (AUC), accuracy, sensitivity, specificity, and heat map were used as indicators of diagnostic efficacy.Results:In the test data set, the AUC for diagnosing the presence of an abnormal optic disc, the presence of ON, and the presence of NAION were 0.967 [95% confidence interval ( CI) 0.947-0.980], 0.964 (95% CI 0.938-0.979), and 0.979 (95% CI 0.958-0.989), respectively. The activation area of the systems were mainly located in the optic disc area in the decision-making process. Conclusion:Abnormal optic disc, ON and NAION, and screening diagnostic systems based on color fundus images have shown accurate and efficient diagnostic performance.

Objective: To explore the risk factors of cytomegalovirus (CMV) infection or reactivation in ulcerative colitis (UC) patients. Methods: We performed a search at the databases of Pubmed, Cochrane, Embase, CNKI, Wanfang, SinoMede and VIP up to March 2017. A search strategy was constructed by using a combination of the following words: "inflammatory bowel disease or IBD" or "ulcerative colitis or UC" and "cytomegalovirus or CMV" . Literature was screened according to the inclusion and exclusion criteria and statistics was analyzed using RevMan 5.3 software provided by Cochrane collaboration network and analyzed using Stata 12.0 software to evaluate publication bias. Results: After searching and screening, we included 18 case-control studies finally. Meta-analysis showed that the risk of CMV infection or reactivation in severe UC was 1.45 times that in mild to moderate UC and the risk in whole colon was 1.54 times that of patients with left colon and rectum with the pooled OR values as 1.45 (1.02-2.05) and 1.54 (1.05-2.27). The risk of CMV infection in middle-aged patients with UC was higher than that in young patients with the pooled MD values of 4.60(2.13-7.07). The therapies with glucocorticoid and immunosuppressive agents such as azathioprine, cyclosporine and methotrexate were high risk factors of CMV infection or reactivation in UC patients, with the pooled OR values as 3.87 (2.70-5.53) and 2.07 (1.29-3.32), but the duration of UC, treatment with 5-Amino salicylic acid/salazosulfapyridine (5-ASA/SASP) and infliximab had no statistically significant correlation with the CMV infection or reactivation in UC patients, with the pooled OR values as -1.20 (-2.64-0.24), 0.94 (0.61-1.42) and 1.50 (0.65-3.44). Conclusions In patients with severe UC, whole colon lesions and the therapy with glucocorticoid and immunosuppressive agents were the risk factors of CMV infection or reactivation. The risk of CMV infection or reactivation in middle-aged patients was higher than that in young patients.

From September 2017 to February 2018, 650 disabled children and adolescents aged 6-to 17-year-old in Beijing were matched 1∶1 to those in normal physical condition with same age, gender and place of residence. All children and adolescents were investigated for self-injury status in the last year to understand the difference of self-injury incidence between groups. Multivariate unconditional logistic regression model was applied for exploring relevant factors of self-injury of children and adolescents. This study found that the disability, insufficient sleep, difficulty falling asleep, and sleeping late were associated with self-injury of children and adolescents.

Objective To investigate the effectiveness of evoked potential in monitoring cerebral perfusion during carotid endarterectomy by a retrospective cohort study.Methods A retrospective cohort survey of clinical data of 59 patients,who underwent carotid endarterectomy in our hospital from September 2013 to December 2016,was performed.All patients were monitored by transcranial doppler ultrasonography (TCD) and somatosensory evoked potential (SEP),motor evoked potential (MEP) for changes of cerebral blood flow;the monitoring of TCD was defaulted as "gold standard",recording monitoring results at different time points.By drawing the four table,the sensitivity,specificity,positive predictive value,negative predictive value of SEP and MEP during cerebral hypoperfusion were calculated,and correlation analyses between SEP and TCD,and between MEP and TCD were performed.Through receiver operating characteristic (ROC) curve,SEP monitoring threshold of cerebral hypoperfusion was predicted.Results The sensitivity,specificity,positive predictive value,and negative predictive value of SEP in predicting intra-operative cerebral hypoperfusion were 60.00％,91.84％,60.00％,and 91.84％ when SEP amplitude declined beyond 50％;the sensitivity,specificity,positive predictive value and negative predictive value of SEP in predicting intra-operative cerebral hypoperfusion were 70.00％,93.88％,70.00％ and 93.88％ when SEP latency extended beyond 10％.The sensitivity,specificity,positive predictive value,and negative predictive value of MEP in predicting intra-operative cerebral hypoperfusion were 30.00％,97.96％,75.00％,and 87.27％ when MEP amplitude declined beyond 50％.Decline of SEP and MEP amplitudes and extension of SEP latency have positive correlations with TCD.ROC indicated that the amplitude of somatosensory evoked potentials could predict intraoperative hypoperfusion when it decreased by 51.0％ than the baseline monitoring value after carotid artery occlusion,with sensitivity of 100.0％,specificity of 89.8％ and area under the curve of 0.918 (95％CI:0.846～0.990,P=0.024).ROC also showed that the latent phase of somatosensory evoked potentials could predict intraoperative hypoperfusion when it was prolonged ＞9.8％ compared to the baseline monitoring value after carotid artery occlusion,with sensitivity of 100.0％,specificity of 92.9％and area under the curve of 0.941 (95％CI 0.878～0.995,P=0.014).Conclusion Evoked potentials can real-time monitor intra-operative cerebral hypoperfusion continuously in carotid endarterectomy,enjoying high sensitivity and specificity;in addition,decline of SEP amplitude and extension of SEP latency have higher sensitivity than MEP.
