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.

China is currently in an accelerated stage of population aging, and brain diseases pose a significant threat to the health of the elderly. " Preventing brain aging and maintaining brain health" has become a high-level goal of healthy aging. During the process of aging, the physiological and psychological states of elderly people change, making them prone to nervousness and exhaustion, which can disturb the brain spirit, damage the brain collaterals, and severely endanger brain health. Starting from the holistic view of cultivating both body and spirit in traditional Chinese medicine, based on the physical and mental characteristics of the elderly, this paper applies the concept and method of " relaxation and tranquility" in the protection of elderly brain health, focusing on maintaining relaxation and tranquility in both physical and mental aspects. Specific measures include emphasizing subjective consciousness, relaxing the heart and calming down; utilizing the daoyin method, relaxing the body and calming down, combining relaxation and tranquility, cultivating both body and spirit to prevent diseases and protect the brain, which enables the elderly to have a healthy mind and body, a sense of happiness and fulfillment, and to age gracefully. Simultaneously, advocating for tranquility is also called " respect" for relaxation, following nature to understand constant changes, and improving one′s ability to think positively in old age, in order to expand ideas for the protection of elderly brain health.

Shared Decision-Making (SDM) is a crucial concept in modern medicine, emphasizing the joint participation of doctors and patients in the medical decision-making process. However, the authoritative position of doctors and the passive role of patients in traditional medical models often overlook the personal wishes and needs of patients, leading to tense doctor-patient relationships and medical disputes. By listening to and understanding their stories, narrative medicine helps doctors gain a more comprehensive understanding of patients’ situations and balances medical advice with patient needs in the decision-making process. Through systematic literature analysis and theoretical exploration, this paper investigated the application effects and mechanisms of narrative medicine in different medical contexts, as well as analyzed its specific role in the process of SDM. The aim is to explore the value of narrative medicine in bridging differences in SDM, revealing its role in promoting doctor-patient communication, enhancing decision-making participation, and improving medical outcomes. Researches had found that narrative medicine enhanced doctors’ “narrative ability”, promoted emotional communication and trust between doctors and patients, reduced conflicts and misunderstandings in decision-making, and improved patients’ sense of participation and trust, thus playing an important role in SDM. Therefore, by enhancing doctor-patient communication and understanding, promoting SDM and treatment selection between doctors and patients, personalized care and treatment optimization, advocating for doctor-patient co-construction, improving consultation efficiency, restoring the patient’s subject position, and other methods, it can bridge doctor-patient differences, promote communication and enhance decision-making participation, and improve medical outcomes and patient satisfaction.

ObjectiveTo construct an animal model of respiratory syncytial virus(RSV)-infected pneumonia suitable for preclinical studies. MethodsThe virulence of RSV to the four cell lines was observed by cytopathic effect (CPE), and 50% tissue culture infective dose(TCID50) was calculated. Twenty BALB/c mice were randomly divided into a normal group and a model group. Six BALB/c-hIGF1R mice served as the humanized IGF1R model group. Except for the normal group, the other groups received intranasal RSV infection on days 1 and 3 to establish a viral pneumonia model. The efficacy of establishing an RSV-induced pneumonia animal model based on humanized insulin-like growth factor 1 receptor (IGF1R) mice was evaluated by measuring organ indices, peripheral blood lymphocyte percentages, pulmonary pathology and imaging, and pulmonary viral load. Additionally, ten BALB/c mice served as normal group, and thirty-two BALB/c-hIGF1R mice were randomly assigned to humanized IGF1R model group, ribavirin group (82.5 mg·kg-¹·d-¹), and high and low dose groups of Lianhua Qingwen (3.3 mg·kg-¹·d-¹ , 1.65 mg·kg-¹·d-¹), with 8 mice per group. The viral load in lung tissue was measured after ribavirin and Lianhua Qingwen intervention, and the model was applied to the evaluation of anti-RSV drugs. ResultsIn the lungs of the humanized IGF1R model group, large solid and diffuse ground-glass shadows were seen, and the lung volume was significantly increased (P<0.01). The lung index was significantly increased (P<0.01), and both the spleen index and thymus index were significantly decreased (P<0.01). The percentages of CD3+ and CD4+T cells were significantly decreased (P<0.05), and there was a large amount of inflammation and stasis in the perivascular area of the lung tissue, which was predominantly characterized by lymphocytes. The endothelium of blood vessels was partially detached, with a small number of eosinophils. After infecting BALB/c-hIGF1R mice with RSV, the expression of viral nucleic acids in the lung tissue of the mice was significantly increased, with significant differences compared with the normal group (P<0.01). The expression of viral nucleic acids in the ribavirin group and the high and low dose groups of Lianhua Qingwen was significantly reduced, with significant differences compared with the normal group (P<0.01). ConclusionHumanized IGF1R mice are more susceptible to respiratory SVC, and the animal model of RSV-infected pneumonia based on humanized IGF1R mice was successfully constructed, which is suitable for the evaluation of anti-RSV drugs.

OBJECTIVE To investigate the effects of Tongxie yaofang (TXYF) on the symptoms of rats with irritable bowel syndrome with diarrhea (IBS-D) by regulating colonic tryptophan hydroxylase 1 (TPH1), serotonin transporter (SERT) and intestinal flora. METHODS Forty-two SD rats were randomly divided into control group (7 rats) and modeling group (35 rats). In modeling group, rat model of IBS-D was established by intragastrical administration of 0.45 g/L senna leaf solution [10 mL/(kg·d)] combined with chronic unpredictable stimulation. Thirty-five successfully modeled rats were randomly divided into model group, pinaverium bromide group [15 mg/(kg·d)] and TXYF low-dose, medium-dose and high-dose groups [3.75、7.5、15 g/(kg·d), calculated by crude drug], with 7 rats in each group. Each administration group was orally administered the corresponding drug, once a day, for 10 consecutive days. The general condition and weight changes of each group of rats were compared before modeling, after modeling and before administration, after the last drug intervention; the diarrhea index and visceral sensitivity were detected, and pathological changes of colon tissue were observed after modeling and before administration, after the last drug intervention. The level and expression of 5-hydroxytryptamine (5-HT), protein and mRNA expressions of TPH1 and SERT were determined in colon tissue. The diversity and structural changes of fecal intestinal flora of rats were analyzed. RESULTS There was no significant change in colon histopathology in each group. Compared with model group, the general condition of rats in each medication group improved. The daily body weight gain of rats was significantly increased, while diarrhea index, visceral sensitivity, the expressions of 5-HT and TPH1 in colon tissue were significantly decreased; SERT expression of colon tissue was significantly increased in TXYF medium-dose and high-dose groups (P<0.05 or P<0.01). The diarrhea index, colon TPH1 protein expression and colon 5-HT protein positive rate in the TXYF low-dose group decreased while the mRNA expression of SERT increased significantly (P<0.05). There was a dose- dependent trend in the effect of TXYF. Compared with model group, Chao1 index and Shannon index of the rats in TXYF high- dose group were significantly decreased (P<0.05 or P<0.01), the beneficial bacteria such as Firmicutes and Lactobacillus increased significantly, while the pathogenic bacteria such as Proteobacteria, Escherichia-Shigella and Rikenellaceae_RC9_gut_ group decreased significantly (P<0.05 or P<0.01). CONCLUSIONS TXYF can decrease the level of 5-HT and improve intestinal flora disorder by inhibiting the expression of TPH1 and up-regulating the expression of SERT in colon tissue, thus promoting the symptoms of IBS-D rats.

Objective To analyze the incidence of prehypertension (PHTN) and hypertension of male workers in a coal mine and investigate the influencing factors. Methods A total of 10 155 male workers in a coal mine in Shanxi Province were selected as the study subjects using the judgment sampling method. Occupational medical examination was carried out to examine the prevalence of abnormal blood pressure (including PHTN and hypertension) and its influencing factors. Results The prevalence of abnormal blood pressure was 69.9%, with a PHTN prevalence of 44.2% and a hypertension prevalence of 25.7%. The results of multinomial logistic regression analysis showed that the risk of PHTN and hypertension increased with age, drinking frequency and body mass index (all P<0.05). Workers with a pulse rate≥100 times/min had a higher risk of PHTN and hypertension than those with a pulse rate of 60-100 times/min (all P<0.05). The risk of PHTN and hypertension in workers exposed to noise, silica dust or other dust was higher than those without such occupational hazard exposure (all P<0.05). The risk of hypertension in workers with abnormal blood glucose was higher than that in workers with normal blood glucose (P<0.05). Exposure to organic solvents was associated with a higher risk of hypertension (P<0.05). Conclusion The prevalence of PHTN and hypertension among male coal miners in this mine is relatively high. The individual factors such as age, alcohol consumption, pulse rate, and body mass index, along with occupational exposure factors such as noise, silica dust, and other dusts, are influencing factors for PHTN and hypertension.

ObjectiveTo observe the effect of water extract of Mori Folium (MLE) on oxidative stress in adipose tissue of type 2 diabetes mellitus (T2DM) mice and explore its mechanism. MethodTwenty-four male db/db mice were randomly divided into model group, metformin group, low-dose MLE (MLE-L) group, and high-dose MLE (MLE-H) group according to their body weight and blood glucose, with six mice in each group, and other six C57BLKS/JGpt wild littermate mice were selected as normal group. The mice in the metformin group were given 200 mg·kg-1 metformin suspension, and the mice in the MLE-L and MLE-H groups were respectively given 2 g·kg-1 and 4 g·kg-1 MLE, while the mice in the normal group and model group were given the same dose of deionized water by daily gavage for eight weeks. Body weight, subcutaneous fat index, fasting blood glucose (FBG), and oral glucose tolerance level (OGTT) of the mice were detected, and serum superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA) were measured. The expression levels of silent information regulator 1 (SIRT1) and NADPH oxidase type 4 (NOX4) protein in subcutaneous adipose tissue of the mice were detected by Western blot. ResultThe FBG level, OGTT, and subcutaneous fat index of T2DM mice were significantly decreased (P<0.05, P<0.01) after administration of MLE compared with the blank group. The contents of serum SOD and GSH were significantly increased, while the level of oxidative stress damage marker MDA was significantly decreased (P<0.05, P<0.01). The expression of SIRT1 protein in adipose tissue was significantly increased, while the expression of NOX4 protein was significantly decreased (P<0.05, P<0.01). ConclusionMLE can ameliorate T2DM by alleviating oxidative stress in adipose tissue of T2DM mice and reducing blood glucose.

ObjectiveTo investigate the protective effects of Mori Folium extract (MLE) on the kidney of db/db diabetic mice and its mechanism. MethodTwenty-four male C57BLKS/JGpt-Leprdb/Leprdb (db/db) mice were randomly divided into model group, metformin group, low-dose group of MLE (MLE-L), and high-dose group of MLE (MLE-H) according to their fasting blood glucose (FBG), with six mice in each group, and other six C57BLKS/JGpt wild littermate (m/m) mice were selected as normal group. The mice in the drug administration groups were given corresponding drugs by gavage, and the mice in the normal group and model group were given the same dose of deionized water by gavage once a day for continuous eight weeks. Body weight, bilateral kidney weight, and FBG were measured, and an oral glucose tolerance test (OGTT) was performed. The pathological changes in the kidney tissue of mice were observed by hematoxylin-eosin (HE) and periodic acid-silver (PAS) staining, and serum creatinine (SCr) and blood urea nitrogen (BUN) levels were detected. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in serum and urinary microalbumin (U-mAlb) of mice. The expression levels of toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), and nuclear factor-kappa B p65 (NF-κB p65) protein in kidney tissue of mice were tested by Western blot. ResultCompared with the normal group, the body weight, absolute renal weight, FBG, and the area under the curve (AUC) of OGTT of mice in the model group were significantly increased (P<0.01), and the levels of SCr, BUN, and U-mAlb, as well as TNF-α and IL-6 in serum were significantly increased (P<0.01). The glomerular basement membrane in the kidney tissue of mice was thicker, with obvious inflammatory cell infiltration. The protein expression levels of TLR4, MyD88, and NF-κB p65 in the kidney tissue of mice were increased significantly (P<0.01). Compared with the model group, there was no statistical difference in the body weight of mice in each drug administration group. The absolute renal weight of mice in the MLE-H and metformin groups was significantly reduced (P<0.05, P<0.01). The FBG levels of mice in the metformin, MLE-L, and MLE-H groups started to decrease after treatment for four to eight weeks (P<0.05, P<0.01). The AUC of mice in the MLE-H and metformin groups was significantly decreased (P<0.01). The levels of SCr, BUN, and U-mAlb of mice in the MLE-H and metformin groups were significantly decreased (P<0.01), and those of SCr and U-mAlb of mice in the MLE-L group were significantly decreased (P<0.01). The levels of TNF-α and IL-6 in the serum of mice in the MLE-H and metformin groups were significantly decreased (P<0.01). The renal tissue pathology of mice in each drug administration group was improved to varying degrees, and the protein expression levels of TLR4, MyD88, and NF-κB p65 in the MLE-H group were decreased significantly (P<0.05, P<0.01). ConclusionMLE can improve the renal structure and function of db/db diabetic mice, and its mechanism may be related to the inhibition of the TLR4/MyD88/NF-κB signaling pathway.
