ObjectiveTo investigate the changes in chemical components of Gardeniae Fructus(GF) before and after being charred, providing data support for research on the material basis of GF Carbonisata(GFC). MethodsUltra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-Q-Orbitrap MS/MS) was used to conduct a comprehensive analysis of the chemical components in GF and GFC under positive and negative ion modes with Compound Discoverer 3.3 software and online database. Then, principal component analysis and partial least squares-discriminant analysis in SIMCA14.1 software were used to analyze the MS data of each sample. Based on the principle of variable importance in the projection(VIP) value>1, differential secondary and primary metabolites before and after carbonization were screened. In addition, MetaboAnalyst website was used for pathway enrichment of Kyoto Encyclopedia of Genes and Genomes(KEGG), so as to provide a reference for clarifying the processing mechanism. ResultsA total of 185 components were identified, including 96 secondary metabolites and 89 primary metabolites. These components were classified into nine categories, primarily including iridoid glycosides, flavonoids, and terpenoids, their fragmentation pathways were also analyzed. Simultaneously, multivariate statistical analysis was performed on the secondary and primary metabolites, identifying 70 and 59 differential metabolites, respectively. The secondary metabolites were enriched in two metabolic pathways, including C5-branched dibasic acid metabolism and flavonoid and flavonol biosynthesis, while the primary differential metabolites were enriched in seven pathways such as linoleic acid metabolism and tyrosine metabolism. ConclusionThe chemical components of GF change significantly after carbonization, with a significant decrease in the contents of iridoid glycosides and terpenoids such as hydroxyisogeniposide, crocin Ⅱ, crocetin, and jasminoside B. while the contents of 4-hydroxycoumarin, geniposidic acid, gentiopicroside, and gardenoside methyl ester increase significantly. This change is presumed to be associated with the enhanced cooling and hemostatic effects of the processed products. The identified key components provide a basis for elucidating the material basis underlying the efficacy changes before and after carbonization.

ObjectiveTo investigate differential metabolites associated with browning in the post-harvest processing of Pinelliae Rhizoma, providing data support for elucidating the key metabolites and metabolic pathways involved in browning, and developing safe and efficient sulfur-free processing techniques. MethodsUltra-performance liquid chromatography-triple quadrupole/linear ion trap mass spectrometry(UPLC-QTRAP-MS/MS) was used to detect the metabolites of Pinelliae Rhizoma at different browning stages(0, 8, 16 h) for widely targeted metabolomics. Subsequently, Multivariate statistical analysis of metabolites was conducted using principal component analysis(PCA), hierarchical cluster analysis(HCA), orthogonal partial least squares-discriminant analysis(OPLS-DA), and K-means cluster analysis. Differential metabolites at different browning stages were screened based on variable importance in the projection(VIP) value>1 and |log2fold change(FC)|≥1, and metabolic pathway enrichment analysis was performed using Kyoto Encyclopedia of Genes and Genomes(KEGG). ResultsA total of 1 416 metabolites were identified across the three browning stages of Pinelliae Rhizoma, predominantly comprising amino acids and their derivatives(239), lipids(219), alkaloids(156), phenolic acids(121), terpenoids(113), and flavonoids(111). A two-by-two comparison of the three browning phases, yielded 622 differential metabolites that were significantly enriched in the phenylpropanoid biosynthesis, flavone and flavonol biosynthesis, and purine metabolic pathway. Further analysis revealed that carbohydrates such as D-mannose and turanose, phenolic acids such as 1-O-caffeoyl-6-O-glucosyl-β-D-glucose, dicaffeoylshikimic acid, and flavonoids such as epigallocatechin gallate, vitexin-7-O-rutinoside, luteolin-7-O-(6″-malonyl)glucoside-5-O-arabinoside, catechin gallate, epicatechin gallate, isovitexin-7-O-glucoside-2″-O-rhamnoside, apigenin-7-O-rutinoside-4ʹ-O-sophoroside, 3,5,3ʹ,4ʹ,5ʹ-penta-hydroxyflavan-7-gallate may act as browning substrates and play important roles in the browning process. ConclusionCarbohydrates, phenolic acids, and flavonoids may serve as key substrates in the browning process of Pinelliae Rhizoma, involving pathways such as phenylpropanoid biosynthesis, flavone and flavonol biosynthesis, and purine metabolism, which can provide a theoretical basis for further exploration of the browning mechanism.

Sangjuyin, as a pungent and cooling agent with precise therapeutic effect, is a classic pungent formula for cooling relief of the epidermis, which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty, on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition, concoction, decoction, efficacy, and previous and modern application of Sangjuyin. After examination, the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris, family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa, family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx, family Labiatae. Mori Folium is the dried leaves of Morus alba, family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium, family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum, family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family, and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum, 5.60 g Forsythiae Fructus, 2.98 g Menthae Haplocalycis Herba, 9.33 g Mori Folium, 3.73 g Chrysanthemi Flos, 7.46 g Platycodonis Radix, 2.98 g Glycyrrhizae Radix et Rhizoma, and 11.19 g Phragmitis Rhizoma, with 400 mL water added, and the solution was boiled to obtain 200 mL, taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat, promoting lung and relieving cough, and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough, pneumonia, rhinitis, and other respiratory diseases, and the results of this study provide a reference for the later development of Sangjuyin.

This article systematically reviews and verifies the name, origin, production area, quality evaluation, harvesting, processing and other aspects of Cynanchi Atrati Radix et Rhizoma(CARR) by consulting relevant ancient and modern literature, in order to provide a basis for the development and utilization of famous classical formulas containing this herb. Through textual research, Baiwei has been the official name for CARR, though it also bears alternative names such as Chuncao, Popo Zhenxianbao, Longdan Baiwei. The mainstream base is the roots and rhizomes of Cynanchum atratum. Historical records indicate primary producing areas include Shandong, Anhui, Jiangsu, Shaanxi and Shanxi. Since the late Ming dynasty, varieties from Juxian, Yishui and Rizhao in Shandong have been highly regarded as authentic, commonly known as eastern Baiwei. Since modern times, its quality has been summarized as fine, slender, and straight fibrous roots, pale yellow exterior, whiter interior, and dryness with easy breakability are considered superior. The harvesting time before the Song dynasty was on the third day of the third lunar month, but after the Song dynasty, harvesting was possible in both spring and autumn. The initial processing methods of CARR in ancient times included drying in the shade, removing Lu(the little rhizomes which are on tap of roots), and removing mustaches, modern methods involve washing and sun-drying. During the Northern and Southern dynasties, processing methods included steaming. In the Song dynasty, drying and light stir-frying were predominant, while wine washing emerged in the Ming dynasty. Modern practices primarily involve using raw, stir-frying or honey processing. Regarding the medicinal properties of CARR, both ancient and modern texts agree it has a bitter and salty taste and is non-toxic. Records prior to the Qing dynasty predominantly describe its nature as extremely cold, while mainstream herbal texts after the Qing dynasty generally characterize it as cold. Before the Ming dynasty, there were no records of its meridian tropism. It was not until the Qing dynasty that it was recorded in the lung meridian. Modern records mainly refer to the stomach, liver, and kidney meridians. Throughout history, its main functions have been to clear heat, diuresis, nourish Yin, and replenish essence, primarily treating Yin deficiency and fever syndrome. Based on the research results, it is suggested that when developing famous classical formulas containing CARR, the dried roots and rhizomes of C. atratum can be selected as its medicinal source. If there are no specific processing requirements, raw products can be selected as medicine. If the processing requirements are specified, corresponding processed products can be selected as medicine according to the original formula requirements.

Perimenopausal depression (PMD) is an affective disorder that occurs in women during the transition from sexual maturity to old age. It can induce various complications, such as insomnia and cognitive decline. The etiology of PMD is complex. Although multiple hypotheses have been proposed, there is still no unified theory that fully explains its pathogenesis. Research into its mechanisms relies heavily on animal experiments, and establishing reliable animal models is crucial for experimental studies. Appropriate animal models can better simulate human pathophysiological states, rapidly evaluate the efficacy and safety of drugs and intervention methods, grasp the essence of the disease, and uncover its intrinsic connections, thereby exploring more advanced intervention strategies. However, there is a lack of systematic review and summarization of literature related to model construction. Additionally, traditional Chinese medicine (TCM), adhering to the principles of ''syndrome differentiation and treatment'' and ''holistic concept'', has shown significant efficacy in treating PMD. In recent years, research exploring and analyzing its therapeutic mechanisms has been increasing. Therefore, to gain a clearer and more comprehensive understanding of PMD animal modeling methods and the mechanisms of TCM, this paper reviewed Chinese and English literature on PMD animal models and mechanisms of TCM in PMD treatment. It summarized the construction methods of single-factor and multi-factor PMD models, and discussed the advantages and disadvantages of each modeling approach. Furthermore, it delved into the mechanisms of TCM intervention in PMD, revealing that TCM formulas primarily exert their effects by regulating the hypothalamic-pituitary-adrenal axis, hypothalamic-pituitary-ovarian axis, gut-brain axis, cell signaling pathways, neural circuits, hormone levels, and neurotransmitter levels. This review aims to provide a reference for future research in this field. In summary, by summarizing the progress in the methods for PMD animal model construction and the mechanisms of TCM, the paper seeks to offer new insights into the mechanistic research of TCM intervention in PMD.

Chaihu Guizhi Ganjiangtang was first recorded in the Treatise on Cold Damage (Shang Han Lun). This prescription is composed of Bupleuri Radix, Scutellariae Radix, Cinnamomi Ramulus, Zingiberis Rhizoma, Trichosanthis Radix, Ostreae Concha, and Glycyrrhizae Radix et Rhizoma. It has the effects of soothing Lesser Yang, warming the spleen, and stimulating the generation of body fluid. It is mainly used to treat digestive tract diseases such as chronic cholecystitis (CC), irritable bowel syndrome, and non-alcoholic fatty liver disease. Dyspepsia caused by CC presents a variety of gastrointestinal symptoms such as abdominal pain, poor appetite, postprandial fullness, aversion to greasy food, soft stool, and bitter mouth, being a type of biliary dyspepsia. In modern medicine, dyspepsia caused by CC is mainly managed by medical treatment and surgical treatment. Internal medicine mainly focuses on reducing inflammation, promoting the function of gallbladder, resolving stones, alleviating spasms, and relieving the pain for CC, demonstrating definite short-term efficacy but suffering from single effects, high recurrence rate, and poor compliance. Although surgical treatment can cure cholecystitis, it is accompanied by the increased incidence of adverse events such as abdominal pain, diarrhea, and dyspepsia. Modern clinical studies have confirmed that Chaihu Guizhi Ganjiangtang can significantly alleviate the symptoms such as abdominal pain and dyspepsia of CC patients. Pharmacological studies have found that Chaihu Guizhi Ganjiangtang mainly contains active ingredients such as Bupleuri Radix saponins, baicalin, cinnamaldehyde, gingerol, Trichosanthis Radix polysaccharide, Ostreae Concha polysaccharide, and Glycyrrhizae Radix et Rhizoma total flavonoids. Chaihu Guizhi Ganjiangtang can ameliorate the symptoms of dyspepsia caused by CC by inhibiting inflammatory responses, improving gallbladder contraction and gastrointestinal motility, regulating the bile acid-intestinal flora axis and the brain-gut axis, and modulating blood lipids through multiple targets. By reviewing the previous literature, this article summarizes the research progress in the treatment of dyspepsia caused by CC with Chaihu Guizhi Ganjiangtang and its main active ingredients as well as the pathogenesis of this disease and puts forward the shortcomings and improvement strategies for the current research. The review aims to provide a reference for the further research on Chaihu Guizhi Ganjiangtang in the treatment of dyspepsia caused by CC.

Breast cancer (BC), a common malignant tumor in women, is characterized by high incidence and mortality rates, posing a serious threat to women's life and health. Currently, the commonly used treatments for BC include surgery, radiotherapy, chemotherapy, molecular targeted therapy, and endocrine therapy. Although radiotherapy and chemotherapy can effectively kill tumor cells and inhibit the proliferation and differentiation of tumor cells, they can induce adverse reactions such as hematopoietic dysfunction and impaired immune function. The other treatment methods also have problems such as drug resistance, high recurrence rates, reduced quality of life, and poor clinical efficacy. Therefore, it is urgent to explore new drugs with better efficacy and lower toxicity. Ferroptosis is a form of iron-dependent, non-apoptotic programmed cell death triggered by lipid peroxidation. In recent years, ferroptosis has become a hot topic in the field of cancer treatment and has been gradually proven to effectively inhibit the proliferation and metastasis of BC cells, reduce the drug resistance of BC to chemotherapy drugs, and enhance the sensitivity of BC to radiotherapy. Traditional Chinese medicine (TCM), with multiple components, multiple targets, and mild side effects, is widely used in the treatment of BC. A large number of studies have shown that active ingredients of TCM, such as saponins, flavonoids, terpenoids, phenols, and polysaccharides, can inhibit the proliferation and metastasis of BC cells by modulating ferroptosis-related pathways. These include iron metabolism, lipid metabolism, cystine/glutamate antiporter system Xc-/glutathione/glutathione peroxidase 4, Specifically, these ingredients elevate the levels of lipid peroxidation, reactive oxygen species, malondialdehyde, and Fe2+ in BC cells, thereby inducing ferroptosis-mediated suppression of tumor progression. This article reviews the relevant literature at home and abroad in recent years, summarizes the mechanisms of ferroptosis in regulating BC and the research progress in the active components of TCM targeting ferroptosis in the intervention of BC, aiming to provide ideas for the development of new drugs for the treatment of BC.

Alzheimer's disease (AD) is a common type of dementia, primarily characterized by cognitive and behavioral impairments as well as deficits in learning and memory. The progression of AD has imposed a significant economic burden on society and families. However, its exact pathogenesis has not yet been fully elucidated. Currently, available therapeutic drugs are limited and are often accompanied by serious adverse effects. Traditional Chinese medicines (TCMs) and their extracts are mostly natural products and possess advantages such as multi-pathway regulation and relatively few adverse reactions. Experimental studies have shown that TCMs exhibit great potential in the prevention and treatment of AD. For example, Huanglian Jieduang, Danggui Shaoyaosan, Kaixin San, Liuwei Dihuangwan, Buyang Huanwutang, as well as Ginseng Radix et Rhizoma, Astragali Radix, Uncariae Ramulus cum Uncis, Coptidis Rhizoma, Gardeniae Fructus, Ginkgo Folium, Salviae Miltiorrhizae Radix et Rhizoma, and Curcumae Longae Rhizoma, can reduce β-amyloid deposition, inhibit excessive Tau protein phosphorylation, restore mitochondrial function, alleviate oxidative stress, suppress neuroinflammation and apoptosis, repair synaptic function, and improve gut microbiota. This article mainly summarizes the effects of several TCMs and compound prescriptions on AD, aiming to provide a reference for subsequent TCM-based treatment of AD.

Intravascular large B-cell lymphoma(IVLBCL) is a rare and aggressive type of lymphoma with diverse and nonspecific clinical manifestations, often leading to misdiagnosis. This article reports a case of IVLBCL in a middle-aged male patient who initially presented with pulmonary arterial hypertension(PAH). The patient exhibited progressive hypoxemia and PAH, showing poor response to standard PAH therapy. Laboratory tests indicated a hyperinflammatory state and significantly elevated lactate dehydrogenase levels, while imaging revealed diffuse bilateral lung lesions. Random skin biopsy identified atypical B lymphocytes within subcutaneous capillaries, confirming the diagnosis of IVLBCL. Following treatment with the ZR-CHOP regimen, the patient's symptoms and laboratory parameters improved markedly. By reviewing relevant literature, this article systematically outlines the diagnostic and therapeutic process of this case, aiming to provide insights for the clinical recognition of such rare presentations.

To summarize the distribution characteristics of human papillomavirus(HPV) infection types in patients with cervical squamous intraepithelial lesion(SIL) and cervical cancer(CC), and to explore the impact of HPV vaccination, HPV infection types, and general clinical data on different grades of cervical lesions. Clinical data of women attending the gynecological colposcopy clinic of Shenzhen People's Hospital from January 2020 to December 2023 were retrospectively collected. Patients with HPV genotyping records and histopathologically diagnosed SIL or CC were included and divided into three groups based on pathological results: low-grade squamous intraepithelial lesion(LSIL) group, high-grade squamous intraepithelial lesion(HSIL) group, and CC group. The distribution of high-risk HPV subtypes was analyzed among the three groups, and multivariate Logistic regression was used to identify influencing factors for high-grade cervical lesions. A total of 4162 patients were included, comprising 4057 cervical SIL patients(3317 LSIL and 740 HSIL) and 105 CC patients. The overall mean age was(39.9±11.2) years. The HPV infection rate was 95.1%(3959/4162), and 25.0%(1040/4162) of patients had received HPV vaccination. Among high-risk HPV infections, HPV 52, HPV 16, HPV 58, and HPV 18 were the most common subtypes. HPV 52 had the highest infection rate in the LSIL group(27.6%), while HPV 16 was the most prevalent in the HSIL group(45.3%) and CC group(64.9%). Multivariate Logistic regression analysis showed that HPV vaccination( HPV infection is common in patients with SIL and CC, but the distribution of high-risk HPV subtypes varies among different grades of cervical lesions. It is recommended to strengthen cervical cancer screening and monitoring of key high-risk HPV infections in older and multiparous women in Shenzhen, and to continue promoting HPV vaccination.
