By reviewing the research history on quality comparison between wild and cultivated Chinese crude drugs, this paper systematically combed the relevant research reports since the 1950s, and summarized and analyzed the results of existing comparative studies, and found that the existing comparative research on the quality of wild and cultivated Chinese crude drugs were mainly focused on several aspects, including characteristics, microstructures, chemical compositions, pharmacodynamic effects, and genetic diversity. Among these, comparative studies of chemical compositions have been the dominant approach, with a particular emphasis on comparing the contents of index components. However, research on pharmacodynamic effects remained relatively limited. Due to various factors such as sample quantity, sample origin, growth period and cultivation methods, the differences in quality between wild and cultivated Chinese crude drugs vary significantly. In general, most wild Chinese crude drugs exhibited higher quality than cultivated products, with significant differences in their characteristics. The contents and proportions of some chemical components underwent noticeable changes, particularly with a marked increase in the proportion of primary metabolites after cultivation. The quality of cultivated Chinese crude drugs is closely related to the cultivation practices employed. Chinese crude drugs produced through wild nurturing, simulated wild planting, ecological cultivation, and other similar methods demonstrate quality levels comparable to those of wild Chinese crude drugs. Based on the analysis results, it is recommended to explicitly specify the cultivation practices and cultivation period of cultivated Chinese crude drugs in comparative studies of the quality between wild and cultivated Chinese crude drugs. Multiple technical approaches, including characteristics, microscopy, non-targeted metabolomics combined with quantitative analysis of differential components, and bioefficacy evaluation, should be employed to comprehensively assess the quality disparities between wild and cultivated Chinese crude drugs. Moreover, research efforts should be intensified to investigate the changes in pharmacodynamic effects resulting from differences in plant cell wall composition, primary metabolites, and secondary metabolites, in order to guide the production of high-quality Chinese crude drugs.

ObjectiveBased on the quality evaluation experience of "it is better to have a fragrant and strong aroma" summarized by materia medica of past dynasties, the chemical components of Sojae Semen Nigrum(SSN) and Sojae Semen Praeparatum(SSP) were systematically compared and analyzed, and the main fermentation products in different fermentation time were quantitatively analyzed, so as to clarify the transformation law of internal components in the processing process and provide scientific basis for the modern quality control of SSP. MethodUltra performance liquid chromatography-quadrupole tandem time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used for the structural identification of the chemical constituents of SSN and SSP, and with the aid of Progenesis QI v2.3 software, the negative ion mode was employed for principal component analysis(PCA) pattern recognition, and the data were analyzed with the aid of orthogonal partial least squares-discriminant analysis(OPLS-DA) for two-dimensional data to obtain S-plot, and components with |P|>0.1 were selected as the differential constituents. The contents of isoflavonoids in SSP during fermentation was determined by UPLC, and the samples were taken every 8 h in the pre-fermentation period and every 2 d in the post-fermentation period, and the dynamic changes of isoflavonoid contents in different fermentation stages were analyzed. The contents of amino acids and nucleosides in SSP and SSN from different fermentation stages were quantitatively analyzed by phenyl isothiocyanate(PITC) pre-column derivatization and high performance liquid chromatography(HPLC) gradient elution, and the contribution of flavor substances to the "delicious" taste of SSP was discussed by taste intensity value(TAV). ResultA total of 19 kinds of differential components were screened out, mainly soybean saponins and isoflavones, and their contents decreased significantly or even disappeared after fermentation. In the pre-fermentation process of SSP, glycoside bond hydrolysis mainly occurred, and isoflavone glycosides in SSN were degraded and converted into the corresponding aglycones, the content of flavor substances such as amino acids increased gradually. In the post-fermentation process, protein degradation mainly occurred, after 8 d of post-fermentation, the content of isoflavones was basically stable, while the total content of amino acids increased by 8-40 times on average. Different amino acids form the special flavor of SSP, such as the TAV of glutamate is always ahead of other flavor substances, and sweet substances such as alanine and valine have made relatively great contributions to SSP. ConclusionBased on the law of constituent transformation, combined with the traditional evaluation index of "fragrant and strong", it is difficult to control the fermentation degree of SSP by the existing standards in the 2020 edition of Chinese Pharmacopoeia. It is suggested that description of the characteristics of SSP be refined and changed to "fragrant, delicious and slightly sweet", and at the same time, the post-fermentation index compounds such as glutamic acid, alanine and valine should be added as the quality control indicators of SSP, so as to standardize the production process and improve the quality of SSP.

The standardization study on disease names in traditional Chinese medicine (TCM) is a key and challenging aspect of the modernization of TCM. TCM disease names refer to a symbolic system established by traditional medicine for the rational definition and denotation of physical and mental distress, characterized by temporal and spatial features, clinical features, and cultural traits. These features are both the characteristics of TCM disease names and the root causes of issues such as weakened application, standardization difficulties, and lack of methodology. In response to these problems, we propose a research idea for TCM disease names. Firstly, appropriate samples should be selected based on application needs, and by constructing models, the alignment of the TCM disease names' refe-rence system in content and form should be facilitated to address the issue of weakened application. Secondly, studies on semantics, pragmatics, and clinical positioning should be conducted simultaneously to promote the empi-rical nature of linguistic symbols and strengthen the clinical features of TCM disease names. Furthermore, research on methodology should be intensified. By fully referencing traditional naming methods and the nomenclature of western scientific fields and theoretically examining complex systems, the intrinsic relationship between classification systems and naming methods should be clarified, thereby completing the standardization study of the construction process of the TCM disease names reference system.

Depression after myocardial infarction is closely related to the theory of ascending and descending of qi and blood. The core pathogenesis is analyzed as disorder of qi and blood, mental damage, uncontrolled upward and downward movement, and pivot movement failure. The treatment method is to regulate qi and blood, invigorate qi and activate blood circulation and restore the rise and fall of visceral qi. Nourishing qi and promoting blood circulation should invigorate qi in the first. Appropriate blood activating drugs should be selected according to the degree of blood stasis, so that the blood circulation is smooth and the spirit has dependence. The key to restoring the normal balance of qi movement of visceral organs is to regulate not only liver ascending and lung descending but also spleen. Clinicians need pay attention to the nature of drug lifting and falling, conforming the physiological functions of the organs, to restore the rising and falling of the qi movement of internal organs.

The clinical efficacy advantages of traditional Chinese medicine (TCM) compound prescriptions have always been inadequately characterized in experimental research,which has become a bottleneck restricting the development of TCM pharmacology and even the progress of TCM. The concept of simultaneous treatment/regulation,guided by the theory of mutual generation and restriction of five zang-organs,has guiding significance in the clinical practice of TCM throughout history and is still widely used in the current clinical practice. However,this unique and clinically valuable diagnostic and therapeutic medication system based on the syndrome differentiation has been completely ignored in the modern research of TCM pharmacology,which might be one of the key factors restricting the pharmacological characterization of the therapeutic advantages of TCM compound prescriptions. On the basis of systematically summarizing the phased progress and achievements of the efficacy evaluation of TCM compound prescriptions,this article explores the path of exploring the pharmacological advantages of TCM compound prescriptions on simultaneous treatment/regulation on the basis of the correlation patterns of five zang-organs,from the theory of Zangxiang,the core concept of five zang-organs,and the TCM disease recognition based on the theory of mutual generation and restriction of five zang-organs. With the heart-lung correlation as a breakthrough point,this study explored a new characterization method for the pharmacological advantages of TCM,aiming to provide new ideas for evaluating the efficacy of TCM compound prescriptions.

With the rapid development of social economy, the number of patients with nervous system diseases has increased, and the incidence of the population has a trend of younger, which has a serious impact on life health and social economy. Artemisinin is an active antimalarial component extracted and isolated from Artemisia annua, a Chinese medicinal material. Artemisinin and its derivatives, in addition to the antimalarial effect, also have anti-parasitic, anti-fungal, anti-viral, hypoglycemic, hypolipidemic, anti-tumor, and anti-inflammatory effects, showing a wide range of pharmacological activities. In the past five years, research on the new pharmacological effects of artemisinin and its derivatives has been deepening, and the efficacy of artemisinin and its derivatives in nervous system diseases has attracted much attention, including anti-neuroinflammation, anti-oxidative stress, maintaining the stability of the blood-brain barrier, regulating the release of neurotransmitters, repairing neuronal damage, and promoting neuronal regeneration. These pharmacological effects indicate that artemisinin and its derivatives are potentially capable of neuroprotection. By sorting out literature on the pharmacological activity of artemisinin and its derivatives in nervous system during 2019-2024, this paper systematically summarized the protective effects of artemisinin and its derivatives against nervous system diseases such as stroke, neurodegenerative diseases, neuroimmunological diseases, neuralgia, and nervous system tumors. This review is expected to provide clues and evidence for new indication expansion of artemisinin drugs, innovative drug development, and clinical treatment of nervous system diseases.

The impact of air pollution on human health has always been a research hotspot in the global health field. Outdoor air pollutants composed of multiple components can enter the human body through various pathways. Cardiovascular diseases are a group of diseases caused by outdoor air pollutants. Studies have shown that the incidence of cardiovascular diseases, including hypertension, arrhythmia, and heart failure, is significantly increased among people exposed to air pollution environments. Air pollutants such as fine particulate matter, nitrogen dioxide, ozone, carbon monoxide, and sulfur dioxide are closely related to the occurrence of cardiovascular diseases, and short-term and long-term exposure causes different cardiovascular risks. By reviewing the relevant research reports from 2019 to 2024, this article summarizes the epidemiological evidence of cardiovascular diseases caused by different air pollutants. It generalizes the pathways through which air pollutants accelerate the progression of cardiovascular diseases. These pathways include oxidative stress, inflammatory response, thrombosis, extracellular vesicle release, endoplasmic reticulum stress, apoptosis, endothelial dysfunction, autonomic nervous system imbalance, and their interactions. Based on the different mechanisms of air pollution on cardiovascular diseases, the article analyzes the main progress in drug intervention and summarizes the roles of various active ingredients and compound prescriptions of traditional Chinese medicine in treating air pollution-related cardiovascular diseases, providing reference for the research on the mechanisms and drug interventions of air pollution-related cardiovascular diseases.

The complex pathophysiological mechanisms between diabetes mellitus and cardiovascular diseases have not yet been fully elucidated, becoming one of the challenges in clinical care. Glucagon-like peptide-1 receptor agonist (GLP1-RA) and sodium glucose cotransporter-2 inhibitors (SGLT2) are clinically used to reduce the cardiovascular risk of patients with diabetes mellitus. Traditional Chinese medicine has diverse biological activities and unique advantages in the treatment of chronic complex diseases due to its multi-component and multi-target effects. Based on recent reports, this paper reviewed the common risk factors of diabetes mellitus and cardiovascular diseases (e.g., hyperglycemia, insulin resistance, and inflammation), related targets such as apolipoprotein C-Ⅲ (APOC3), S100 calcium-binding protein A8/A9 (S100A8/A9), growth/differentiation factor-15 (GDF-15), and NACHT, LRR, and PYD domains-containing protein 3 (NLRP3), advanced glycation end products, insulin resistance, endothelial dysfunction, endoplasmic reticulum stress, mitochondrial dysfunction, and intestinal flora disorder. In addition, this paper summarized the research progress in the treatment of cardiovascular diseases in diabetes mellitus with the active ingredients (e.g., baicalein, puerarin, curcumin, notoginsenoside, and tanshinone ⅡA), single herbal medicines (e.g., Astragali Radix, Ginseng Radix et Rhizoma, Sophorae Flavescentis Radix, Cinnamomi Cortex, and Corni Fructus), and compound formulas (e.g., Buzang Tongluo Fang, Yiqi Yangyin Huoxue Fang, Shenqi Fang, Huangqisan, Danggui Buxue Tang, and Liuwei Dihuang Wan) of traditional Chinese medicine. Traditional Chinese medicine mainly treats cardiovascular diseases in diabetes mellitus by reducing inflammation and oxidative stress, ameliorating dyslipidemia and insulin resistance, protecting islet β cell function, repairing endothelial damage, inhibiting smooth muscle cell proliferation, foam cell formation, macrophage polarization, and cardiac hypertrophy and fibrosis, and regulating intestinal flora disorder. These processes involve insulin receptor substrate/ phosphatidylinositol 3-kinase/protein kinase B (IRS/PI3K/Akt), peroxisome proliferator-activated receptor α/γ (PPAR α/γ), nuclear factor-kappa B (NF-κB), adenosine 5′-monophosphate (AMP)-activated protein kinase (AMPK), hypoxia-inducible factor-1-BCH domain-containing protein (HIF-1-BNIP), vascular endothelial growth factor/hypoxia-inducible factor-1α (VEGF/HIF-1α) and other signaling pathways. This review is expected to provide a theoretical basis and reference for the treatment of cardiovascular diseases in diabetes mellitus with traditional Chinese medicine.

Objective:To explore the current situation of the intrinsic capacity of elderly people in the community and analyze its influencing factors.Methods:From September 2022 to March 2023, convenience sampling was used to select 360 elderly community residents from Xicheng District, Beijing, and Xingtai City, Hebei Province, as the research subjects. The subjects were surveyed using the Intrinsic Capacity Assessment Questionnaire, Intrinsic Capacity Influencing Factors Questionnaire, Barthel Index, and Lawton Instrumental Activities of Daily Living Scale.Results:A total of 360 questionnaires were distributed, and 360 valid questionnaires were collected, with an effective response rate of 100.0% (360/360). The overall impairment rate of intrinsic capacity among 360 elderly people in the community was 90.3% (325/360), and the impairment rates in various fields from high to low were sensation, psychology, vitality, cognition, and exercise. Multiple linear regression analysis showed that age, gender, residential pattern, education level, work status, grip strength, number of geriatric syndrome, self-rated health status, adverse life events, number of social activities, transportation conditions, and social security were the influencing factors of the intrinsic capacity of elderly people in the community, and the difference was statistically significant ( P<0.05) . Conclusions:The impairment rate of intrinsic capacity among elderly people in the community is relatively high. Grassroots medical and nursing staff should assess the intrinsic capacity of elderly people in the community in health promotion work, identify elderly people with decreased intrinsic capacity early and carry out effective interventions to prevent elderly people from becoming disabled and dependent on care.
