Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

Immobilized enzyme-based enzyme electrode biosensors, characterized by high sensitivity and efficiency, strong specificity, and compact size, demonstrate broad application prospects in life science research, disease diagnosis and monitoring, etc. Immobilization of enzyme is a critical step in determining the performance (stability, sensitivity, and reproducibility) of the biosensors. Random immobilization (physical adsorption, covalent cross-linking, etc.) can easily bring about problems, such as decreased enzyme activity and relatively unstable immobilization. Whereas, directional immobilization utilizing amino acid residue mutation, affinity peptide fusion, or nucleotide-specific binding to restrict the orientation of the enzymes provides new possibilities to solve the problems caused by random immobilization. In this paper, the principles, advantages and disadvantages and the application progress of enzyme electrode biosensors of different directional immobilization strategies for enzyme molecular sensing elements by specific amino acids (lysine, histidine, cysteine, unnatural amino acid) with functional groups introduced based on site-specific mutation, affinity peptides (gold binding peptides, carbon binding peptides, carbohydrate binding domains) fused through genetic engineering, and specific binding between nucleotides and target enzymes (proteins) were reviewed, and the application fields, advantages and limitations of various immobilized enzyme interface characterization techniques were discussed, hoping to provide theoretical and technical guidance for the creation of high-performance enzyme sensing elements and the manufacture of enzyme electrode sensors.

OBJECTIVE To investigate the impact of dapagliflozin on contrast-induced acute kidney injury (CIAKI) and prognosis in patients with diabetes mellitus type 2 (T2DM) and acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI). METHODS Retrospective selection of data on T2DM patients with ACS who underwent PCI treatment in the Cardiology Department of Tianjin Chest Hospital from January 1st 2021 to December 31st 2022. The patients were divided into dapagliflozin group (96 cases) and control group (148 cases) based on whether they received dapagliflozin or not. Renal function indicators were measured for all enrolled patients before PCI and at 48 h and 1 week after PCI, including blood urea nitrogen (BUN), serum creatinine (Scr), estimated glomerular filtration rate (eGFR), cystatin-C (Cys-C), kidney injury molecule-1 (KIM-1) and β2-microglobulin (β2-MG). All patients were followed up for at least 1 year. The incidence of CIAKI and major adverse cardiac event (MACE) during follow-up were recorded for both groups. Logistic regression was used to analyze the impact of dapagliflozin on the occurrence of CIAKI, while the Log-rank test was applied to compare the incidence of MACE between the two groups. Cox regression was employed to analyze the impact of dapagliflozin on prognosis. RESULTS At 48 h and 1 week after PCI, serum levels of Cys-C, KIM-1 and β2-MG were significantly lower in the dapagliflozin group compared to the control group (P<0.05). The incidence of CIAKI was lower in the dapagliflozin group compared to the control group (6.25% vs. 14.86%, P=0.042). Logistic regression analysis revealed that dapagliflozin was an independent protective factor against CIAKI (OR=0.280, 95%CI 0.101-0.780,P=0.015). During the follow-up period, the incidence of MACE was lower in the dapagliflozin group compared to the control group (7.29% vs. 17.57%, P=0.049). Cox regression analysis indicated that dapagliflozin reduced the occurrence of MACE after PCI (HR=0.374, 95%CI 0.161-0.866, P=0.022). CONCLUSIONS With adequate hydration, the use of dapagliflozin does not increase the risk of CIAKI following PCI in T2DM patients with ACS.

[Objective] To analyse and predict the tendencies of using erythrocyte blood in Changsha based on the autoregressive integrated moving average (ARIMA) model, long short-term memory (LSTM) and ARIMA-LSTM combination model, so as to provide reliable basis for designing a feasible and effective blood inventory management strategy. [Methods] The data of erythrocyte usage from hospitals in Changsha between January 2012 and December 2023 were collected, and ARIMA model, LSTM model and ARIMA-LSTM combination model were established. The actual erythrocyte consumption from January to May 2024 were used to assess and verify the prediction effect of the models. The extrapolation prediction accuracy of the models were tested using two evaluation indicators: mean absolute percentage error (MAPE) and root mean square error (RMSE), and then the prediction performance of the model was compared. [Results] The RMSE of LSTM model, optimal model ARIMA(1,1,1)(1,1,1)12 and ARIMA-LSTM combination model were respectively 5 206.66, 3 096.43 and 2 745.75, and the MAPE were 18.78%,11.54% and 9.76% respectively, which indicated that the ARIMA-LSTM combination model was more accurate than the ARIMA model and LSTM model, and the prediction results was basically consistent with the actual situation. [Conclusion] The ARIMA-LSTM model can better predict the clinical erythrocyte consumption in Changsha in the short term.

Pulmonary hypertension (PH) is a severe and rare chronic cardiopulmonary disorder for which existing vasodilator therapies can only alleviate symptoms, rather than target or fundamentally reverse the disease. Additionally, the long-term prognosis remains poor. Recent studies have found that some novel anti-tumor drugs (NADs) can relieve PH, such as imatinib, gefitinib, sorafenib, olaparib, piperacillin, everolimus, rituximab, etc. However, some NADs can induce PH or exacerbate its symptoms, including dasatinib, lorlatinib, carfilzomib, bevacizumab, trastuzumab, nivolumab, etc. The effects of lapatinib, ruxolitinib, and bortezomib on PAH are controversial. Individualized medication should be adopted in clinical practice when using NADs for treatment, with close monitoring being essential.

ObjectiveTo analyze the characteristic expression patterns of six neurotransmitters including 5-hydroxytryptamine (5-HT), dopamine (DA), acetylcholine (ACh), norepinephrine (NE), inhibitory neurotransmitter (INH), and excitatory neurotransmitter (EXC) in the whole brain and different brain regions of depression patients by Search of Encephalo Telex (SET), providing new ideas for the study of heterogeneous etiology of depression. Methods(1) A retrospective study was conducted on supra-slow signals of EEG fluctuations in 1 028 patients with depression. The SET system was used to obtain the expression information of six neurotransmitters in the whole brain and 12 brain regions: left frontal region (F3), right frontal region (F4), left central region (C3), right central region (C4), left parietal region (P3), right parietal region (P4), left occipital region (O1), right occipital region (O2), left anterior temporal region (F7), right anterior temporal region (F8), left posterior temporal region (T5), and right posterior temporal region (T6). The expression information of each neurotransmitter was compared with the normal model, and it was found that single neurotransmitter was in one of three states: increased, decreased, or normal expression. The simultaneous expression states of six neurotransmitters in the brain space were referred to as the expression pattern of multiple neurotransmitters. (2) A MySQL database was established to analyze the actual expression patterns of different neurotransmitters in the whole brain of patients with depression. (3) Factor analysis was conducted to further analyze the characteristic rules of 78 variables of neurotransmitters in the whole brain and 12 brain regions in depression patients. Results(1) The expression of single neurotransmitters in the whole brain and different brain regions of the total depression population showed one of three expression states (increased/decreased/normal), being normal in the majority. The decreased and increased expression of 5-HT, ACh, DA, INH, EXC, and NE in the whole brain occurred in 6% and 25%, 31% and 17%, 36% and 9%, 15% and 31%, 32% and 14%, and 22% and 22%, respectively. (2) The antagonizing pairs of neurotransmitters (EXC/INH, DA/5-HT, and ACh/NE) showed significant antagonistic relationships in the whole brain and different brain regions, with a strong negative correlation between EXC and INH (P<0.01, |r| values ranging from 0.69 to 0.76), a strong negative correlation between DA and 5-HT (P<0.01, |r| values ranging from 0.83 to 0.90), and a moderate negative correlation between ACh and NE (P<0.01, with |r| values ranging from 0.56 to 0.66). Meanwhile, non-antagonizing pairs of neurotransmitters in the whole brain and different brain regions also showed correlations, with DA/NE (P<0.01, |r| values ranging from 0.38 to 0.46) and NE/EXC (P<0.01, |r| values ranging from 0.56 to 0.61) showing weak and moderate negative correlations, respectively, and DA/EXC showing a weak positive correlation (P<0.01, |r| values ranging from 0.38 to 0.47). (3) The six neurotransmitters in the 1 028 patients with depression presented a total of 170 expression patterns in the whole brain. The top 30 expression patterns were reported in this paper, with a cumulative rate of 60.60%, including patterns ① INH+/5-HT-/ACh+/DA+/NE-/EXC- (9.05%), ② INH+/5-HT-/ACh↓/DA+/NE-/EXC- (4.57%), and ③ INH+/5-HT-/ACh+/DA+/NE↓/EXC- (3.31%). That is, the proportion of depression patients with normal levels of all the six neurotransmitters was 9.05%, and the patients with at least one neurotransmitter abnormality accounted for 91.95%. (4) The factor analysis extracted 22 common factors from 78 variables in the whole brain and different brain regions. These common factors showed the absolute values of loadings ranging from 0.32 to 0.86 and the eigenvalues (F) ranging from 1.03 to 13.43, with a cumulative contribution rate of 76.82%. The characteristic expression patterns included ① AChP3↓/AChW↓/AChC3↓/AChF3↓/AChO1↓/AChT5↓/AChF7↓/NEP3↑/NEW↑/NEC3↑/NEF3↑/NEO1↑/NET5↑/NEF7↑ (F=13.43, whole brain), ② 5-HTO2↑/DAO2↓/5-HTP4↑/DAP4↓/5-HTW↑/DAW↓/5-HTC4↑/DAC4↓ (F=5.94), and ③ EXCF4↓/DAF4↓/NEF4↑/INHF4↑/5-HTF4↑/AChF4↓ (F=5.33). ConclusionThe actual 170 expression patterns of 6 neurotransmitters in the whole brain of 1 028 depression patients indicate that depression is a heterogeneous disease with individualized characteristics. The 22 characteristic expression patterns in the whole brain and 12 brain regions verify the pathogenesis hypothesis of multi-neurotransmitters oscillation imbalance in brains of depression patients. In summary, this study provides new guidance for the etiology, diagnosis, and treatment of depression and establishes a methodological foundation for the effectiveness evaluation of individualized treatment of depression by traditional Chinese medicine based on the objective biological markers.
