Alzheimer's disease （AD） is one of the most common diseases in the elderly population. Its etiology involves multiple pathogenic factors and pathological links such as abnormal deposition of β amyloid protein （Aβ）， hyperphosphorylation of Tau protein， abnormalities of the cholinergic system， oxidative stress， and inflammatory response. However， its specific pathogenesis has not been clarified， and no specific therapeutic drugs have been found. In recent years， more and more studies have paid attention to the potential of chemical components of traditional Chinese medicine （TCM） in the treatment of AD. However， the diversity and complexity of the chemical components of TCM may have a positive impact on multiple pathological links of AD. Researchers have isolated many active components from TCMs， and the effects of treating AD have been confirmed by modern pharmacological studies. Through literature analysis， this article found that the main chemical components of TCM with anti-AD effects were saponins （31%）， flavonoids （24%）， polysaccharides （20%）， lactones （8%）， alkaloids （7%）， phenols （3%）， and other compounds （7%）. Among them， ginsenoside， notoginsenoside， epimedium flavones， puerarin， baicalein， schisandra polysaccharide， angelica polysaccharide， ganoderma lucidum polysaccharide， pachyman， huperzine A， berberine， andrographolide， curcumin， emodin， and gastrodin have been extensively studied in terms of their anti-AD effects， and their mechanisms of pharmacological action have been involved in many aspects of AD pathogenesis. This article reviews the anti-AD activities and possible mechanisms of chemical components of TCM， so as to provide a reference for the development of new drugs for the prevention and treatment of AD.

Objective To explore the effect of Tianma Gouteng Yin combined with butylphthalein(NBP)on symptom improvement and vascular elasticity in patients with acute cerebral infarction(ACI).Methods Eighty-two ACI patients admitted to Lu'an Hospital of Traditional Chinese Medicine were included in this study,and they were randomly separated into the single group and the combination group,with 41 cases in each group.The single group was given intravenous infusion of NBP sodium chloride injection,and the combination group was given treatment with Tianma Gouteng Yin on the basis of the single group.Cerebrovascular reserve function,endothelial function,neurological function,independent living ability,hemodynamic indicators,vascular elasticity,clinical efficacy and incidence of adverse reactions were compared between the two groups of patients at 1 day after admission(T0)and 14 days after treatment(T1).Results There were no significant differences in cerebrovascular reserve function,endothelial function,National Institutes of Health Stroke Scale(NIHSS)scores,independent living ability scores,hemodynamic indicators and vascular elasticity indicators at T0 between the two groups(P＞0.05).At T1,levels of cerebrovascular reactivity(CVR),nitric oxide(NO),nitric oxide synthase(NOS),large artery elasticity index(C1)and small artery elasticity index(C2)were significantly increased in both groups,and levels were higher in the combined group than those of the single group(P＜0.05).At T1 moment,levels of ET-1,vascular endothelial growth factor(VEGF),NIHSS score,MRS score,red blood cell count,whole blood viscosity,platelet adhesion rate and arterial pressure were reduced in both groups,and levels were lower in the combined group than those of the single group(P＜0.05).The total effective rate was higher in the combination group(80.5%)than that of the single group(46.3%).The overall incidence of adverse reactions was lower in the combined group than that in the single group(P＜0.05).Conclusion Tianma Gouteng Yin combined with NBP can effectively improve the cerebral vascular reserve function,endothelial function and neurological damage in ACI patients,increase vascular elasticity and improve hemodynamic levels.

Objective:To compare the differences in inhaled medication prescriptions among patients with chronic obstructive pulmonary disease (COPD) who visited the Global Initiative for Chronic Obstructive Pulmonary Disease (GOLD 2023) one year after its release and the previous year, and to analyze the impact of GOLD 2023 on physician inhaled medication prescriptions.Methods:This study was a cross-sectional study, with data sourced from the RealDTC study. The study subjects were chronic obstructive pulmonary disease patients who visited the respiratory and critical care departments of 13 hospitals in southern China from November 14, 2021 to November 15, 2023. According to the time of patient visits, they are divided into the following two groups: the group 1 year before the release of GOLD 2023 (November 14, 2021 to November 14, 2022), and the group 1 year after the release of GOLD 2023 (November 15, 2022 to November 15, 2023). We collected demographic characteristics, lung function, symptom scores, history of acute exacerbation in the past year, and inhaled medication prescriptions from patients. According to the symptom score of COPD patients in GOLD 2023 and their history of acute exacerbation in the past year, they were divided into three groups: A, B, and E. The treatment status of inhaled drugs in groups A, B, and E before and after the release of GOLD 2023 was compared.Results:There were statistically significant differences in COPD Assessment Test (CAT) scores, Modified Medical Research Council (mMRC) scores, and the number of acute exacerbations in the past year between patients with COPD before and after the release of GOLD 2023 (all P<0.05). Compared with the group one year before the release of GOLD 2023, the proportion of patients in the group one year after the release of GOLD 2023 using long-acting muscarinic antagonists (LAMA) and inhaled corticosteroids (ICS)+ long-acting β2-receptor agonists (LABA) was lower, while the proportion of patients using LABA+ LAMA and ICS+ LABA+ LAMA was higher (all P<0.05). There was no statistically significant difference ( P>0.05) in the proportion of patients in group A using LAMA between the year before and after the release of GOLD 2023. Compared to the year before the release of GOLD 2023, the proportion of patients in group A who prescribed ICS+ LABA was lower, while the proportion of using LABA+ LAMA and ICS+ LABA+ LAMA was higher (all P<0.05); The proportion of patients in group B who prescribed LAMA and ICS+ LABA was lower (all P<0.05), while the proportion of using LABA+ LAMA and ICS+ LABA+ LAMA was higher (all P<0.05); The proportion of patients in group E who prescribed LAMA and ICS+ LABA was lower (all P<0.05), while the proportion of using LABA+ LAMA and ICS+ LABA+ LAMA was higher (all P<0.05). Conclusions:After the release of GOLD 2023, the prescription of ICS+ LAMA in groups A, B, and E decreased, and the prescriptions of LABA+ LAMA and ICS+ LABA+ LAMA increased compared to before; However, in the real world, the compliance of physicians with GOLD 2023 is still not ideal.

Objective: This study’s objective is to assess the efficacy and safety of Pulsed Magnetic Therapy System (PMTS) in improving insomnia disorder. Methods: Participants with insomnia disorder were randomly assigned to receive either PMTS or sham treatment for four weeks (n= 153; PMTS: 76, sham: 77). Primary outcomes are the Insomnia Severity Index (ISI) scores at week 0 (baseline), 1, 2, 3, 4 (treatment), and 5 (follow-up). Secondary outcomes are the Pittsburgh Sleep Quality Index at baseline and week 4, and weekly sleep diary-derived values for sleep latency, sleep efficiency, real sleep time, waking after sleep onset, and sleep duration. Results: The ISI scores of the PMTS group and the sham group were 7.13±0.50, 11.07±0.51 at week 4, respectively. There was a significant group×time interaction for ISI (F3.214, 485.271=24.25, p<0.001, ηp 2=0.138). Only the PMTS group experienced continuous improvement throughout the study; in contrast, the sham group only experienced a modest improvement after the first week of therapy. At the end of the treatment and one week after it, the response of the PMTS group were 69.7% (95% confidence interval [CI]: 58.6%–79.0%), 75.0% (95% CI: 64.1%–83.4%), respectively, which were higher than the response of the sham group (p<0.001). For each of the secondary outcomes, similar group×time interactions were discovered. The effects of the treatment persisted for at least a week. Conclusion PMTS is safe and effective in improving insomnia disorders.

Cardiovascular diseases are the leading cause of death in the world today. Atherosclerosis （AS） is a chronic inflammatory disease characterized by thickening or functional degeneration of the arterial wall， and in the later stage of the disease， plaque ruptures to induce thrombosis， which in turn causes ischemia in tissues or organs. It is therefore the pathological basis for all types of cardiovascular diseases. Nuclear transcription factor kappa B （NF-κB）， an important nuclear transcription factor in the inflammatory response， is activated to mediate the transcription of inflammatory factors that can trigger or exacerbate the development of AS. Vascular endothelial cells are activated by inflammatory factors. NF-κB mediates related regulatory genes in endothelial cells to secrete adhesion molecules， chemokines， and coagulation factors， promotes selective aggregation of monocytes， up-regulates the expression of adhesion molecules to make adhesion molecules stick to the endothelium and move toward the intima， promotes the degradation of the extracellular matrix， and forms unstable plaques. In recent years， traditional Chinese medicine （TCM） has achieved certain results in the prevention and treatment of AS， and many Chinese medicines have been proved to be effective in resisting AS and can act on multiple targets in the human body， affecting the occurrence and development of AS in different links. This paper mainly introduced the NF-κB pathway and its relationship with AS， reviewed research progress on 75 components of different types in Chinese medicine monomers such as flavonoids， terpenoids， and alkaloids in AS resistance based on the NF-κB pathway， and found that Chinese medicine monomers mainly regulate cholesterol balance， inhibit the inflammatory response， reduce cell proliferation， inhibit intercellular adhesion， and suppress foam cell formation by regulating the NF-κB pathway to provide a reference for the prevention and treatment of AS.

Glycyrrizae Radix et Rhizoma has high medicinal value and is widely used in compatibility. It is used most frequently in the compatibility of Chinese medicine prescriptions，and is known as ''Guolao''（national medicine） and "master of all medicines". The characteristic active ingredients are mainly liquitin，glycyrrizic acid，glycyrrizin，and licochalcone. In different compatibilities，based on traditional and modern pharmacological theories，the corresponding effect of Glycyrrizae Radix et Rhizoma are brought into play through different mechanisms. Based on the traditional pharmacology of Glycyrrizae Radix et Rhizoma for tonifying spleen，replenishing Qi，clearing heat，removing toxin，dispelling phlegm，relieving cough and pain，and harmonizing various medicines，this paper used herbal authentication to analyze its compatibility application and mechanism. It was found that Glycyrrizae Radix et Rhizoma played corresponding effect in compatibilities through "tonification"，"harmonization"，and "regulation". For example，Glycyrrizae Radix et Rhizoma was combined with tonics including Ginseng Radix et Rhizoma and Atractylodis Macrocephalae Rhizoma to tonify the five Zang-organs through its strong tonifying effect，combined with Paeoniae Radix Alba and Aconiti Lateralis Radix Praeparata to relieve emergencies and pains through harmonizing medicine power and properties，and combined with Rhei Radix et Rhizoma and Natrii Sulfas to reduce medicine intensity through regulating medicine properties and body characteristics. The application law and mechanism of the modern pharmacological compatibility of Glycyrrizae Radix et Rhizoma were analyzed by data mining and network pharmacology. It was found that the modern clinical formula was often compatible with Glycyrrizae Radix et Rhizoma for anti-inflammation，cardiovascular and cerebrovascular protection，anti-virus，and anti-tumor，Ephedrae Herba and Scutellariae Radix for anti-inflammation，Bambusae Caulis in Taenias，Salviae Miltiorrhizae Radix et Rhizoma，and Aurantii Fructus Immaturus for cardiovascular and cerebrovascular protection，and Ophiopogonis Radix and Chuanxiong Rhizoma for nerves protection. Meanwhile，the important targets of the characteristic ingredients were protein kinase B1 （Akt1），interleukin-6 （IL-6），tumor necrosis factor （TNF），and epidermal growth factor receptor （EGFR）. The important characteristic pathways such as tyrosine kinase inhibitor resistance pathway and cyclic guanosine monophosphate （cGMP）/protein kinase G （PKG） signal pathway played the role of cardiovascular and cerebrovascular protection，and proteoglycan pathway in cancer played a neuroprotective role. This study is expected to provide references for the rational compatibility and application of Glycyrrizae Radix et Rhizoma，as well as the compatibility application of Chinese medicine prescriptions.
