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.

In addition to providing energy for cells, mitochondria also participate in calcium homeostasis, cell information transfer, cell apoptosis, cell growth and differentiation. Therefore, maintaining mitochondrial homeostasis is very crucial for the body to carry out normal life activities. Ubiquitination, a post-translational modification of proteins, is involved in various physiological and pathological processes of cells by regulating mitochondrial homeostasis. However, the mechanism by which ubiquitination regulates mitochondrial homeostasis has not been summarized, especially the effect of Parkin protein on cardiovascular diseases. In this paper, the specific mechanism of mitochondrial homeostasis regulated by ubiquitination of Parkin protein is discussed, and the influence of mitochondrial homeostasis imbalance on cardiovascular diseases is reviewed, with a view to providing potential therapeutic strategies for the clinical treatment of cardiovascular diseases.

Objective This study aimed to investigate the lipid-lowering activity of LFBEP-C1 in high glucose-fed Caenorhabditis elegans(C.elegans). Methods In this study,the fermented barley protein LFBEP-C1 was prepared and tested for its potential anti-obesity effects on C.elegans.The worms were fed Escherichia coli OP50(E.coli OP50),glucose,and different concentrations of LFBEP-C1.Body size,lifespan,movement,triglyceride content,and gene expression were analyzed.The results were analyzed using ANOVA and Tukey's multiple comparison test. Results Compared with the model group,the head-swing frequency of C.elegans in the group of LFBEP-C1 at 20 μg/mL increased by 33.88%,and the body-bending frequency increased by 27.09%.This indicated that LFBEP-C1 improved the locomotive ability of C.elegans.The average lifespan of C.elegans reached 13.55 days,and the body length and width of the C.elegans decreased after LFBEP-C1 intake.Additionally,LFBEP-C1 reduced the content of lipid accumulation and triglyceride levels.The expression levels of sbp-1,daf-2,and mdt-15 significantly decreased,while those of daf-16,tph-1,mod-1,and ser-4 significantly increased after LFBEP-C1 intake.Changes in these genes explain the signaling pathways that regulate lipid metabolism. Conclusion LFBEP-C1 significantly reduced lipid deposition in C.elegans fed a high-glucose diet and alleviated the adverse effects of a high-glucose diet on the development,lifespan,and exercise behavior of C.elegans.In addition,LFBEP-C1 regulated lipid metabolism mainly by mediating the expression of genes in the sterol regulatory element-binding protein,insulin,and 5-hydroxytryptamine signaling pathways.

OBJECTIVE To explore the impact of placental polypeptide on the Runt-related transcription factor 3 (RUNX3)/ Notch signaling pathway in rats with cyclophosphamide-induced premature ovarian failure (POF), and its effects on ovarian function and oxidative stress. METHODS A POF rat model was induced by intraperitoneal injection of cyclophosphamide. Sixty POF rats of the model were randomly assigned to model group, low-dose (1 mg/kg) and high-dose (2 mg/kg) placental polypeptide groups, placental polypeptide plus empty vector group [placental polypeptide (2 mg/kg), empty vector (1 μg)], and placental polypeptide plus RUNX3 silencing group [placental polypeptide (2 mg/kg), RUNX3 small interfering RNA (1 μg)], with 12 rats in each group. Additionally, 12 healthy rats were selected as a control group. The intervention lasted for 4 weeks for all groups. After the final administration, the levels of sex hormones [estradiol (E2), anti-Müllerian hormone (AMH), follicle- stimulating hormone (FSH)] in rat serum and oxidative stress indicators [malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), reactive oxygen species (ROS)] in ovarian tissue were measured. The pathology of rat ovarian tissue and apoptosis of ovarian granulosa cells were examined; the expression of apoptosis-related proteins [caspase-3, cleaved-caspase-3, B-cell lymphoma-2 (Bcl-2), Bcl-2 associated X protein (Bax)and RUNX3/Notch signaling pathway-related proteins in rat ovarian tissue were detected. RESULTS Compared with the model group, the low and high doses of placental polypeptide groups showed an increase in the number of normal follicles and a marked decrease in the number of atretic follicles, with significant increases in the serum levels of E2 and AMH, the ovarian tissue levels of SOD and CAT, as well as the expression levels of Bcl-2, RUNX3 and Notch1 proteins, and significant decreases in the serum FSH levels, the ovarian granulosa cell apoptosis rate, and the ovarian tissue levels of MDA and ROS, as well as the expression levels of cleaved-caspase-3, caspase-3 and Bax proteins (P<0.05); the changes in the high-dose group were significantly more pronounced (P<0.05). Compared with the high-dose placental polypeptide group and the placental polypeptide plus empty vector group, the placental polypeptide plus RUNX3 silencing group showed a decrease in the number of normal follicles and a significant reversal of the above indicators (P<0.05). CONCLUSIONS Placental polypeptide may alleviate the symptoms of rats with POF by upregulating the RUNX3/Notch signaling pathway, improving sex hormone secretion, oxidative stress, ovarian granulosa cell apoptosis and ovarian function.

This experiment aims to study the taste-masking effects of different kinds of corrigent used individually and in combination on ibuprofen oral solution, in order to optimize the taste-masking formulation. Firstly, a wide range of corrigent and the mass fractions were extensively screened using electronic tongue technology. Subsequently, a combination of sensory evaluation, analytic hierarchy process (AHP)-fuzzy mathematics evaluation, and Box-Behnken experimental design were employed to comprehensively assess the taste-masking effects of different combinations of corrigent on ibuprofen oral solution, optimize the taste-masking formulation, and validate the results. The study received ethical approval from the Review Committee of the Beijing University of Chinese Medicine (ethical code: 2024BZYLL0102). The results showed that corrigent fractions and types were screened separately through single-factor experiments. Subsequently, a Box-Behnken response surface design combined with AHP and fuzzy mathematics evaluation was used to fit a functional model:

Objective:To investigate the precipitating and aggravating factors in patients with fibromyalgia (FMS) compared to patients with rheumatoid arthritis (RA).Methods:This study was conducted from January 2015 to November 2021, using a cross-sectional survey research method, based on references to develop a patient-reported "onset and exacerbation triggers questionnaire", and surveyed patients with FMS and RA at the same time, and counted the types and proportions of onset and exacerbation triggers in the two groups of patients and used the chi-square test to make comparisons between the groups.Results:A total of 415 patients with FMS and 200 patients with RA participated the survey. 146 patients with FMS (35.2%) and 38 patients with RA (19.0%) reported morbidity triggers. Experiencing physical injury (71, 17.1%), wind-cold/cold-dampness (30 patients, 7.2%), mental stress (26, 6.2%), and exercise fatigue (10 patients, 2.4%) were the common morbidity triggers for FMS. More FMS patients reported to have experienced physical injuries and mental stress before the onset of the disease compared to RA patients [8.2%(17/200), χ2=5.41, P=0.020; 1.5%(3/200), χ2=6.82, P=0.009]. Exacerbation triggers were reported by 319 patients with FMS (76.9%) and 137 patients with RA (68.5%), in the order of weather changes (219 patients, 52.7%), physical labor (192 patients, 46.2%), mood swings (147 patients, 35.4%), sleep deprivation (145 patients, 34.9%), and mental stress (130 patients, 31.3%). The proportion of FMS patients with symptom exacerbation due to physical labor [46.2%(192/415)], mood swings[35.4%(147/415)], sleep deprivation[34.9%(145/415)], mental stress[31.3%(130/415)], and infection [9.3%(39/415)] was significantly higher than that of RA patients [35.0%(70/200), χ2=7.00, P=0.008; 19.5%(39/200), χ2=16.22, P<0.001; 13.5%(27/200), χ2=30.79, P<0.001; 17.5%(35/200), χ2=13.14, P<0.001; 3.0%(6/200), χ2=8.15, P=0.004). Conclusion:More than a third of FMS patients reported precipitating factors, and nearly four fifths FMS patients reported at least one aggravating trigger. FMS patients are likely to be more sensitive to environmental changes and perceived stress than RA patients.
