Objective: To investigate the Alzheimer's disease (AD) influencing factors among the elderly, so as to provide a basis for early prevention and intervention. Methods: From March to June 2024, participants aged 60 years and above from a sub-district in Haishu District, Ningbo City, Zhejiang Province were selected using a convenience sampling method. Data on demographics, lifestyle, and health status were collected through questionnaire surveys. Depressive symptoms were evaluated using the short-form Geriatric Depression Scale. The Chinese Mini-Mental State Examination (MMSE) was used for the initial screening of AD, and individuals who screened positive were further diagnosed by psychiatrists. Factors affecting AD among the elderly were analyzed using a multivariable logistic regression model. Results: A total of 3 644 individuals were surveyed, comprising 1 526 males (41.88%) and 2 118 females (58.12%). The mean age was (71.85±7.44) years. AD was detected in 200 cases, with a detection rate of 5.49%. Multivariable logistic regression analysis showed that individuals aged ≥65 years (65-<70 years, OR=3.012, 95%CI: 1.007-9.012; 70-<75 years, OR=3.131, 95%CI: 1.059-9.260; 75-<80 years, OR=5.779, 95%CI: 1.989-16.784; ≥80 years, OR=16.810, 95%CI: 5.926-47.685), those who were unmarried, divorced, or widowed (OR=1.973, 95%CI: 1.383-2.815), those with hearing loss (OR=1.573, 95%CI: 1.128-2.193), those with diabetes mellitus (OR=1.958, 95%CI: 1.362-2.814), and those with depressive symptoms (OR=4.143, 95%CI: 2.997-5.728) had a higher risk of AD. Conversely, individuals with an educational level of primary school or above (primary school, OR=0.579, 95%CI: 0.401-0.835; junior high school or above, OR=0.438, 95%CI: 0.259-0.741), and those who engaged in regular physical exercise (OR=0.414, 95%CI: 0.264-0.649) had a lower risk of AD. Conclusions The detection rate of AD was relatively high among the elderly in Haishu District. AD among the elderly was related to age, educational level, marital status, physical exercise, hearing loss, diabetes mellitus, and depressive symptoms.

Diabetic peripheral neuropathy(DPN)is a group of neurodegenerative diseases involving the peripheral nervous system.Long chain non-coding RNA(lncRNA)is an important regulatory factor in normal life activities and disease development,widely involved in gene expression regulation,epigenetic regulation,transcription and control and other biological processes.In recent years,a large number of studies have found that lncRNAs can affect the development of DPN by participating in the pathogenesis of DPN such as metabolic disorders,oxidative stress,neuroinflammation,vascular damage,cell autophagy,apoptosis and so on.This paper elaborates on the regulatory role of lncRNAs in the pathogenesis of DPN,with a view to providing scientific references and new ideas for clinical research.

Cancer is one of the deadliest diseases affecting the health of human beings. With limited therapeutic options available, complementary and alternative medicine has been widely adopted in cancer management and is increasingly becoming accepted by both patients and healthcare workers alike. Chinese medicine characterized by its unique diagnostic and treatment system is the most widely applied complementary and alternative medicine. It emphasizes symptoms and ZHENG (syndrome)-based treatment combined with contemporary disease diagnosis and further stratifies patients into individualized medicine subgroups. As a representative cancer with the highest degree of malignancy, pancreatic cancer is traditionally classified into the "amassment and accumulation". Emerging perspectives define the core pathogenesis of pancreatic cancer as "dampness-heat" and the respective treatment "clearing heat and resolving dampness" has been demonstrated to prolong survival in pancreatic cancer patients, as has been observed in many other cancers. This clinical advantage encourages an exploration of the essence of dampness-heat ZHENG (DHZ) in cancer and investigation into underlying mechanisms of action of herbal formulations against dampness-heat. However, at present, there is a lack of understanding of the molecular characteristics of DHZ in cancer and no standardized and widely accepted animal model to study this core syndrome in vivo. The shortage of animal models limits the ability to uncover the antitumor mechanisms of herbal medicines and to assess the safety profile of the natural products derived from them. This review summarizes the current research on DHZ in cancer in terms of the clinical aspects, molecular landscape, and animal models. This study aims to provide comprehensive insight that can be used for the establishment of a future standardized ZHENG-based cancer animal model.

Chronic heart failure （CHF） is a clinical syndrome resulting from damage to the myocardium， leading to changes in the function or structure of the heart and causing reduced pumping and/or filling capacity. Its pathogenesis is complex， potentially involving myocardial fibrosis， apoptosis and autophagy of cardiomyocytes， inflammatory responses， oxidative stress， and myocardial remodeling. Our team believes that the fundamental pathogenesis of CHF is heart-Qi deficiency， with the disease location in the heart， which is closely related to other organs. Due to heart-Qi deficiency， blood circulation weakens， leading to blood stasis， which in turn generates water-dampness and phlegm turbidity that accumulate over time and become toxic. The interaction between water stasis， Qi stagnation， blood stasis， and phlegm toxicity further weakens the body， creating a vicious cycle （deficiency， stasis， water retention， and toxicity） that is difficult to resolve. Under physiological conditions， the nuclear factor-κB （NF-κB） signaling pathway functions normally， maintaining vital activities and immune responses. However， in pathological states， the NF-κB signaling pathway becomes imbalanced， triggering inflammatory responses and other issues. Research has shown that traditional Chinese medicine （TCM） can regulate the NF-κB signaling pathway through multiple pathways， targets， and effects， effectively improving the progression of CHF. As a result， this has become a research hotspot for the prevention and treatment of the disease. Guided by TCM theory， this research group reviewed the literature to summarize the activation pathways of the NF-κB pathway and its interactions with other pathways. Additionally， the group summarized the research progress on the regulation of the NF-κB pathway in the treatment of CHF using Chinese medicines， their active ingredients， Chinese medicine compounds， and Chinese patent medicines. This study is expected to clarify the mechanisms and targets by which TCM treats CHF by regulating the NF-κB pathway， thereby guiding clinical treatment and drug development for CHF.

Programmed death-1 (PD-1) is an inhibitory immune checkpoint that binds to programmed death-ligand 1 (PD-L1) to regulate the immune response and maintain immune system homeostasis of the immune system. Through overexpression of PD-L1, tumor cells bind to PD-1 on the surface of immune cells, inhibiting the activity and function of immune cells, leading to immune escape of cancer cells and tumor progression. Gastrointestinal cancer is a common malignancy with a high mortality rate worldwide, and the effectiveness of current systematic treatment options is limited. In recent years, immune checkpoint inhibitors (ICIs) such as PD-1/PD-L1 inhibitors have attracted much attention in cancer therapy. Immunotherapy has been incorporated into the treatment of some gastrointestinal malignancies. Different from traditional treatment, it uses various means to stimulate and enhance the immune function of the body to achieve the therapeutic purpose of controlling and eliminating tumor cells. However, although PD-1/PD-L1 inhibitors have shown potential in the treatment of gastrointestinal tumors, the efficacy of single inhibitor therapy is limited, which may be due to the ability of tumors to escape immune attack through other pathways after inhibitor treatment, or the presence of other immunosuppressive factors. For example, PD-1 and PD-L1 inhibitors can be combined with other immune checkpoint drugs, molecularly targeted drugs, or chemotherapy drugs to simultaneously act on different immune pathways and improve the comprehensive effect of immunotherapy. However, to achieve an effective combination therapy, we need to delve into the specific mechanisms of action of the PD-1/PD-L1 axis in the development and progression of gastrointestinal tumors, which can help to develop the best treatment strategy and provide individualized treatment options for the appropriate patient population. Therefore, future studies should focus on the regulatory mechanisms of PD-1/PD-L1 axis and evaluate the therapeutic effects of different treatment combinations on gastrointestinal tumors. In this paper, we review the research progress of PD-1/PD-L1 axis in tumorigenicity and its mechanism, and review the single and combined treatment strategies of PD-1 and PD-L1 inhibitors in gastrointestinal tumors.

Objective: To investigate the factors affecting depression and anxiety symptoms among the elderly, so as to provide the basis for promoting mental health among the elderly. Methods: The elderly aged 60 years and above in Ningbo City, Zhejiang Province were recruited using the multistage stratified random sampling method from June to August 2022, and demographic information, lifestyle and self-rated health status were collected by questionnaires. The symptoms of depression and anxiety were assessed by the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7), respectively. The presence of depressive and anxiety symptoms was determined when both the PHQ-9 score and the GAD-7 score were 10 points and higher. Factors affecting depressive and anxiety symptoms were identified using a multivariable logistic regression model. Results: A total of 7 771 individuals were surveyed, including 3 490 males (44.91%) and 4 281 females (55.09%), and had a mean age of (72.11±6.79) years. The prevalence of depression and anxiety symptoms was 2.05%. Multivariable logistic regression analysis identified residence (urban area, OR=0.316, 95%CI: 0.201-0.498), sedentary duration (<3 h/d, OR=0.349, 95%CI: 0.232-0.525; 3-5 h/d, OR=0.458, 95%CI: 0.313-0.671), physical activity (≥3 times/week, OR=0.551, 95%CI: 0.373-0.815), sleep quality (poor, OR=2.491, 95%CI: 1.738-3.571), social isolation (OR=1.688, 95%CI: 1.148-2.481) and self-rated health (poor, OR=5.857, 95%CI: 3.547-9.671; normal, OR=1.903, 95%CI: 1.234-2.937) as the influencing factors for depression and anxiety symptoms among the elderly. Conclusion The prevalence of depression and anxiety symptoms among the elderly is associated with residence, sedentary duration, sleep quality, physical activity, social interactions and self-rated health status.

Osteoscarcopenia (OS) is a common degenerative syndrome in the elderly, which is caused by a decrease in both bone and muscle mass during the aging process, leading to osteoporosis and sarcopenia, a decrease in body balance, and a risk of falls and fractures, posing a serious threat to the quality of life and lifespan of the elderly. Osteoskeletal dystrophy increases with age, and its occurrence is higher in females than that in males. At present, there is no unified diagnostic standard, making it impossible to achieve early detection and intervention. The commonly used diagnostic methods include quantitative computed tomography (CT), magnetic resonance imaging (MRI), dual energy X-ray absorptiometry (DXA), muscle mass bioelectrical impedance analysis (BIA), as well as daily gait speed (UGS), short physical performance battery (SPPB), timed start test (TUG), and biochemical evaluation indicators to improve early diagnosis and screening. Due to the fact that both bones and muscles belong to the motor system, osteoporosis and sarcopenia share common pathogenic factors in genetics, endocrine, paracrine, and fat infiltration, which interact and regulate each other, inducing the occurrence of osteoscarcopenia. Osteoporosis and sarcopenia, two age-related diseases, share the same pathogenesis and regulatory pathways, as well as common drug targets. For example: somatostatin α‑actin-3, peroxisome proliferator activated receptor γ coactivation factor-1α (PGC-1α), myocyte enhancer factor-2 (MEF2C), sterol regulatory element binding transcription factor 1 (SREBF1), protoadhesion 7 (PCDH7) and methyltransferase like 21C (METTL21C), osteocalcin and bone derived bone factor gap junction connexin 43 (Cx43), growth hormone (GH), sex hormones, and diseases (such as tumors, diabetes, polycystic ovary syndrome, cardiovascular disease, anemia, disability, inflammatory disease), aging, nutrition, and poor living habits are closely related to osteosarcopenia. Osteoporosis is characterized by low bone mass and microstructural degeneration of bone tissue, while sarcopenia is characterized by loss of muscle mass, strength, and function, both of which often coexist in the elderly population. Exercise regulates muscle and skeletal cytokines such as myostatin (MSTN) and irisinβ‑aminoisobutyric acid (BAIBA), brain derived neutrophil factor (BDNF), interleukin, prostaglandin E2, Wnt, osteocalcin (OCN), and transforming growth factor‑β (TGF‑β) and receptor activator of NF-κB ligand (RANKL) interfere with each other to prevent and treat osteoscarcopenia. Wnt/β‑catenin signaling pathway can simultaneously regulate the growth and metabolism of bones and muscles, and promote osteoblast proliferation, maturation, and mineralization by increasing OPG/RANKL, which is beneficial for bone mass increase and induces proliferation of muscle satellite cells, stimulating and promoting increased muscle synthesis. NF‑κB pathway is the main regulatory factor for inflammation mediated muscle atrophy. Meanwhile, NF‑κB DNA can participate in RANKL inducing osteoclast differentiation in bone tissue, thereby reducing bone mass. Although exercise and nutrition can improve the symptoms of osteoporosis, they cannot be completely cured, and there are no specific drugs in clinical practice that can cure sarcopenia. Because osteoscarcopenia has a common crosstalk mechanism in the aging process, it is of great significance to prevent osteoscarcopenia by improving bone mass and muscle content through exercise, nutrition, and medication.

italic>Platycodon grandiflorum (Jacq.) A. DC is one of the most commonly used bulk medicinal herbs. It has important value in the fields of medicine, food and cosmetics, and its market demand is increasing year by year, and it has a good development prospect. In this study, based on 403 distribution records and 8 environmental variables, we used Maxent model to predict the potential distribution of P. grandiflorum under climate change. The results showed that the model simulation effect was the best when the Maxent parameter was FC (feature combination) = LQPH (L: linear features; Q: quadratic features; P: product features; H: hinge features) and RM (regularization multiplier) = 2.1, AUC (area under curve) = 0.901, and the model prediction showed that P. grandiflorum was widely distributed in 28 provinces of China under the current climate conditions, with a suitable area of 2 337 419.98 km². Under the influence of climate change in the future, the area of suitable habitat of P. grandiflorum showed a decreasing trend, and the distribution center as a whole showed a trend of northward and eastward shift. The distribution area of P. grandiflorum in the three main producing areas is affected by climate change, and the overall trend is that the future suitable distribution area of Chifeng in Inner Mongolia increases, while the future suitable distribution area of Zibo in Shandong and Taihe, Bozhou in Anhui decreases or even disappears under the SSP5-8.5 scenario (shared socioeconomic pathways). It is suggested to maintain and protect the ecological environment and germplasm resources of the reserved area suitable for the growth of P. grandiflorum, and increase the cultivation research in the expansion area of P. grandiflorum, so as to lay a foundation for the subsequent expansion of P. grandiflorum planting and to promote the protection and sustainable development of P. grandiflorum resources.

Abstract Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive dysfunction and behavioral impairments. Currently, the treatment mainly relies on pharmacotherapy, yet its effectiveness is limited and accompanied by adverse reactions. Multimodal non-pharmacological interventions (MNPI), which combine two or more non-pharmacological intervention approaches, can synergistically improve cognitive function, neuropsychiatric symptoms, activities of daily living, and quality of life in AD patients, and offers advantages of safety, cost-effectiveness and simplicity. This article reviews MNPI-related literature published domestically and internationally from 2018 to 2024, and focuses on the application of cognitive training, physical activity, and other combined intervention methods in MNPI, providing the reference for developing personalized interventions for AD.
