In this paper, by referring to ancient and modern literature, the textual research of Inulae Flos has been conducted to clarify the name, origin, production area, quality evaluation, harvesting, processing and others, so as to provide reference and basis for the development and utilization of famous classical formulas containing this herb. After textual research, it could be verified that the medicinal use of Inulae Flos was first recorded in Shennong Bencaojing of the Han dynasty. In successive dynasties, Xuanfuhua has been taken as the official name, and it also has other alternative names such as Jinfeicao, Daogeng and Jinqianhua. The period before the Song and Yuan dynasties, the main origin of Inulae Flos was the Asteraceae plant Inula japonica, and from the Ming and Qing dynasties to the present, I. japonica and I. britannica are the primary source. In addition to the dominant basal species, there are also regional species such as I. linariifolia, I. helianthus-aquatili, and I. hupehensis. The earliest recorded production areas in ancient times were Henan, Hubei and other places, and the literature records that it has been distributed throughout the country since modern times. The medicinal part is its flower, the harvesting and processing method recorded in the past dynasties is mainly harvested in the fifth and ninth lunar months, and dried in the sun, and the modern harvesting is mostly harvested in summer and autumn when the flowers bloom, in order to remove impurities, dry in the shade or dry in the sun. In addition, the roots, whole herbs and aerial parts are used as medicinal materials. In ancient times, there were no records about the quality of Inulae Flos, and in modern times, it is generally believed that the quality of complete flower structure, small receptacles, large blooms, yellow petals, long filaments, many fluffs, no fragments, and no branches is better. Ancient processing methods primarily involved cleaning, steaming, and sun-drying, supplemented by techniques such as boiling, roasting, burning, simmering, stir-frying, and honey-processing. Modern processing focuses mainly on cleaning the stems and leaves before use. Regarding the medicinal properties, ancient texts describe it as salty and sweet in taste, slightly warm in nature, and mildly toxic. Modern studies characterize it as bitter, pungent, and salty in taste, with a slightly warm nature. Its therapeutic effects remain consistent across eras, including descending Qi, resolving phlegm, promoting diuresis, and stopping vomiting. Based on the research results, it is recommended that when developing famous classical formulas containing Inulae Flos, either I. japonica or I. britannica should be used as the medicinal source. Processing methods should follow formula requirements, where no processing instructions are specified, the raw products may be used after cleaning.

This article systematically reviews and verifies the historical evolution of Stemonae Radix from the aspects of name, origin, harvesting and processing, quality and others by consulting ancient and modern literature, in order to provide reference for the development and utilization of famous classical formulas containing this medicinal herb. Stemonae Radix has a long history of application, and it derives its name from its distinctive growth pattern, featuring clusters of ten to several dozen underground tuberous roots. This morphology resembles that of certain plants in the genus Asparagus, leading to historical instances where tuberous roots from genus Asparagus were mistakenly used as Stemonae Radix. After the research, it can be concluded that Stemonae Radix was first recorded in Mingyi Bielu, and throughout history, Baidu has been recognized as its official name, though it also bears alternative names such as Baibing, Pofucao and Ye Tianmendong. The mainstream sources used throughout history have been the dried tuberous roots of Stemona sessilifolia, S. japonica or S. tuberosa from the family Stemonaceae. This aligns with the 2025 edition of Pharmacopoeia of the People's Republic of China(hereinafter referred to as Chinese Pharmacopoeia). Additionally, Asparagus filicinus and A. officinalis from the genus Asparagus are common sources of confusion with Stemonae Radix. The three primitive plants are mainly distributed in the Yangtze River basin and southern China, exhibiting a wide distribution. Historically, wild harvesting was predominant, but cultivation is now established. In ancient times, the harvesting time was mostly in the second, third, and eighth lunar months, when roots were harvested and dried. Nowadays, it is more common to pick and excavate in the spring and autumn seasons. After excavation, the roots are washed, fibrous roots removed, briefly blanched in boiling water or steamed until no white core remains, and then sun-dried or oven-dried. In ancient times, the processing of Stemonae Radix primarily involved roasting(stir-frying), wine roasting, or raw materials. Modern mainstream processing specifications include two types of raw and honey-roasted products. In terms of quality evaluation of the medicinal materials, ancient criteria of "preferring plump and moist roots" align with modern requirement favoring "thick, robust stems with firm texture". Evaluating quality with authenticity, since the Song dynasty, it has been highly praised to produce in Chuzhou and Hengyang as the best. It was an ancient method of fixing the production area to stabilize the medicinal origin, reflecting the ancient recognition of the therapeutic efficacy of plants belonging to the genus Stemona. The main functions of Stemonae Radix remain consistent throughout history, including relieving coughs, eliminating phlegm and parasites. Based on the research results, it is recommended that when developing famous classical formulas containing the medicinal material Stemonae Radix, the botanical source specified in the 2025 edition of Chinese Pharmacopoeia should be selected. The specific species can be determined according to the distribution of resources and the main production areas, and the origin and corresponding botanical source should be fixed. Processing methods should be chosen based on the prescription requirements. It is recommended to use raw products without specified requirements.

By systematically combing ancient and modern literature, this paper examined Tribuli Fructus and Astragali Complanati Semen(ACS) used in the famous classical formulas from the aspects of name, origin, production area, harvesting and processing, clinical efficacy, so as to provide a basis for the development of famous classical formulas containing such medicinal materials. The results showed that the names of Tribuli Fructus in the past dynasties were mostly derived from its morphology, and there were nicknames such as Baijili, Cijili and Dujili. The name of ACS in the past dynasties were mostly originated from its production areas, and there were nicknames such as Baijili, Shayuan Jili and Tongjili. Because both of them had the name of Baijili, confusion began to appear in the Song dynasty. In ancient and modern times, the main origin of Tribuli Fructus were Tribulus terrestris, and ancient literature recorded the genuine producing areas of Tribuli Fructus was Dali in Shaanxi and Tianshui in Gansu, but today it is mainly cultivated in Anhui and Shandong. The fruit is the medicinal part, harvested in autumn throughout history. There is no description of the quality of Tribuli Fructus in ancient times, and the plump, firm texture, grayish-white color is the best in modern times. Traditional processing methods for Tribuli Fructus included stir-frying and wine processing, while modern commonly used is purified, fried and salt-processed. The ancient records of Tribuli Fructus were spicy, bitter, and warm in nature, with modern research adding that it is slightly toxic. The main effects of ancient and modern times include treating wind disorders, improving vision, promoting muscle growth, and treating vitiligo. The mainstream base of ACS used throughout history is Astragalus complanatus. Ancient texts indicated ACS primarily originated from Shaanxi province. Today, the finest varieties come from Tongguan and Dali in Shaanxi. The medicinal part is the seed, traditionally harvested in autumn. Modern harvesting occurs in late autumn or early winter, followed by sun-drying. Ancient texts valued seeds with a fragrant aroma as superior, while modern standards prioritize plump, uniform and free of impurities. Traditional processing methods for ACS included frying until blackened and wine-frying, while modern practice commonly employs purification methods. In terms of medicinal properties, the ancient and modern records are sweet and warm in nature. Due to originally classified under Tribuli Fructus, its effects were thus regarded as equivalent to those of Tribuli Fructus, serving as the medicine for treating wind disorders, additional functions included tonifying the kidneys and treating vitiligo. The present record of its efficacy is to tonify the kidney and promote Yang, solidify sperm and reduce urine, nourish the liver and brighten the eye, etc. Based on the textual research results, it is suggested that when developing the famous classical formulas of Tribuli Fructus medicinal materials, we should pay attention to the specific reference object of Baijili, T. terrestris and A. complanatus should be identified and selected, and the processing method should be in accordance with the requirements of the formulas.

Objective:
To investigate the influencing factors for kinesiophobia among elderly patients with chronic obstructive pulmonary disease (COPD), so as to provide the reference for alleviating kinesiophobia among COPD patients.
Methods:
From December 2023 to July 2024, COPD patients aged 60 years and above who sought medical treatment at a tertiary grade-a hospital in Guiyang City were selected. Demographic information was collected through questionnaire surveys. Kinesiophobia, exercise self-efficacy, social support, type D personality and coping styles were assessed using the Chinese version of Tampa Scale for Kinesiophobia, the Chinese version of the Self-Efficacy for Exercise Scale, Social Support Rating Scale, Type D Personality Scale and Chinese version of the Medical Coping Modes Questionnaire, respectively. Factors affecting kinesiophobia among elderly patients with COPD were analyzed using a multiple linear regression model.
Results:
A total of 300 COPD patients were surveyed, including 238 males (79.33%) and 62 females (20.67%). The majority of patients had a disease duration of less than 5 years, with 130 cases (43.33%). The average kinesiophobia score was (48.01±7.74) points. The average exercise self-efficacy score was (3.39±1.01) points. The average social support score was (34.42±6.76) points. There were 280 patients (93.33%) with type D personality. The average scores of the confrontation, avoidance, and resignation dimensions of coping styles were (17.42±5.00), (13.76±1.91), and (11.81±2.95) points, respectively. Multiple linear regression analysis showed that age (70-<80 years, β'=0.124; ≥80 years, β'=0.205), educational level (primary school and below, β'=0.228; junior high school, β'=0.182), household monthly income per capita (<3 000 yuan, β'=0.234; 3 000~<5 000 yuan, β'=0.165), social support (β'=0.294), type D personality (β'= 0.170), and coping styles (confrontation dimension, β'=-0.140; avoidance dimension, β'=0.154; resignation dimension, β'=0.175) statistically associated with kinesiophobia among elderly patients with COPD.
Conclusion
Kinesiophobia among elderly patients with COPD is associated with age, educational level, household monthly income per capita, social support, type D personality and coping styles.

This article systematically analyzes the historical evolution of the name, origin, medicinal parts, harvesting, processing and others of Chrysanthemi Indici by referring to the herbal medicine, medical books, prescription books and other documents of the past dynasties, combined with the relevant modern research materials, in order to provide a basis for the development of famous classical formulas containing this medicinal herb. According to the research, Chrysanthemi Indici was first recorded under the name Kuyi in Bencao Jingjizhu, with aliases such as Yeshanju, Huangjuzai and Lubianju. The botanical source of Chrysanthemi Indici throughout history was Chrysanthemum indicum of the Asteraceae family. It is now distributed in most areas of China, and since the Qing dynasty, the product from Suichang, Zhejiang has been highly regarded. The whole plant can be used as medicine. According to the natural growth laws, the roots were collected in the first lunar month, leaves in the third, stems in the fifth, flowers in the ninth, and fruits in the eleventh, all of which were dried in the shade. In modern times, Chrysanthemi Indici is harvested during their initial blooming in autumn and winter. Since Bencao Gangmu listed Chrysanthemi Indici as a single medicinal material and clarified that all parts have medicinal value, ancient herbal texts began to record the independent medicinal use of Chrysanthemi Indici Flos, and the use of flowers as medicine has become mainstream. In modern times, the quality of Chrysanthemi Indici Flos is summarized to be best when they are dry, yellow, complete, and fragrant. Because Chrysanthemi Indici has a bitter and pungent taste, and is warm, it can eliminate and disperse, often using the power of alcohol to reach and ascend, and is commonly used to treat carbuncles, boils, and scrofula, with consistent properties and effects throughout ancient and modern times. Based on the research results, it is suggested that Chrysanthemi Indici involved in the formulas can be used as C. indicum, which can be used according to the medicinal parts labeled in the original formulas and the requirements of processing, while those without clear medicinal parts and requirements of processing should be used as the whole plant of the dried raw products.

Systemic lupus erythematosus (SLE) is an autoimmune disease accompanied by various complications, and the exact etiology remains unclear. Treatments for SLE encompass hormone therapy, plasma exchange and immunoadsorption, and targeted biological therapies. Berbamine (BBM), a cellular immunopotentiator with diverse biological functions, has not been reported to have immunomodulatory and therapeutic effects on SLE. The mice were divided into control group, model group, positive control group, low, medium and high BBM groups. In control group, C57BL/6J wild mice received intraperitoneal injection of saline. In model group, MRL/lpr lupus mice were treated with intraperitoneal injection of saline. In positive control group, MRL/lpr lupus mice received intragastric administration of hydroxychloroquine sulfate tablets [Plaquenil, 150 mg/(kg·d)]. In BBM groups, MRL/lpr lupus mice received intragastric administration of different concentration of BBM respectively [20 mg/(kg·d), 50 mg/(kg·d), 100 mg/(kg·d)]. After 8 weeks of treatment, blood was collected from the retro-orbital venous plexus, and ELISA was used to detect the levels of anti-double-stranded DNA (dsDNA) antibodies, antinuclear antibodies (ANA), and anti-small nuclear ribonucleoprotein/Sm (snRNP/Sm) antibodies. Spleen tissues were collected for analysis of Th1/Th2 ratio by flow cytometry. The RNA and protein of spleen were extracted, and the levels of T-box transcription factor T-bet and GATA3 (GATA binding protein 3) mRNA and protein were detected by qRT-PCR and Western blot. The proliferation of white blood cells in the blood was tested by blood routine test. The histopathological changes of kidneys of each group were detected by HE staining. Compared with the model group, the levels of ANA, anti-dsDNA, and anti-snRNP/Sm antibodies were significantly reduced in the BBM-treated groups. The Th1/Th2 ratio was significantly decreased in the model group, but reversed by BBM. Compared with the control group, T-bet expression was significantly downregulated, while GATA3 expression was significantly upregulated in the model group. After BBM intervention, T-bet expression significantly increased, while GATA3 expression decreased compared with the model group. The number of white blood cells significantly decreased in the model group, and increased in the BBM-treated groups. In the model group, the glomerular mesangial and endothelial cells showed significant hyperplasia, clear thrombus was observed in the dilated capillaries, and inflammatory cells infiltrated in the renal interstitium. In medium and high BBM groups, the infiltration of inflammatory cells and capillary thrombosis were significantly decreased. In conclusion, BBM exhibits certain immunomodulatory effects on SLE and promotes the proliferation of white blood cells.

A primary hallmark of pathological cardiac hypertrophy is excess protein synthesis due to enhanced translational activity. However, regulatory mechanisms at the translational level under cardiac stress remain poorly understood. Here we examined the translational regulations in a mouse cardiac hypertrophy model induced by transaortic constriction (TAC) and explored the conservative networks versus the translatome pattern in human dilated cardiomyopathy (DCM). The results showed that the heart weight to body weight ratio was significantly elevated, and the ejection fraction and fractional shortening significantly decreased 8 weeks after TAC. Puromycin incorporation assay showed that TAC significantly increased protein synthesis rate in the left ventricle. RNA-seq revealed 1,632 differentially expressed genes showing functional enrichment in pathways including extracellular matrix remodeling, metabolic processes, and signaling cascades associated with pathological cardiomyocyte growth. When combined with ribosome profiling analysis, we revealed that translation efficiency (TE) of 1,495 genes was enhanced, while the TE of 933 genes was inhibited following TAC. In DCM patients, 1,354 genes were upregulated versus 1,213 genes were downregulated at the translation level. Although the majority of the genes were not shared between mouse and human, we identified 93 genes, including Nos3, Kcnj8, Adcy4, Itpr1, Fasn, Scd1, etc., with highly conserved translational regulations. These genes were remarkably associated with myocardial function, signal transduction, and energy metabolism, particularly related to cGMP-PKG signaling and fatty acid metabolism. Motif analysis revealed enriched regulatory elements in the 5' untranslated regions (5'UTRs) of transcripts with differential TE, which exhibited strong cross-species sequence conservation. Our study revealed novel regulatory mechanisms at the translational level in cardiac hypertrophy and identified conserved translation-sensitive targets with potential applications to treat cardiac hypertrophy and heart failure in the clinic.

A high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS) method was established for simultaneous determination of seven characteristic components from the active fraction of Alpiniae Officinarum Rhizoma in rat plasma, including galangin, kaempferol, kaempferide, pinocembrin, 1,7-diphenyl-4-en-3-heptanone, 5-hydroxy-7-(4-hydroxy-3-methoxyphenyl)-1-phenyl-3-heptanone(DHPA), and 7-(4-hydroxy-3-methoxyphenyl)-1-phenyl-4-en-3-heptanone(DPHB). The new developed HPLC-MS/MS method was applied to study the pharmacokinetics of the 7 characteristic components in rats with Helicobacter pylori gastritis. A Waters Sunfire C_(18) column(2.1 mm×150 mm, 3.5 μm) was used. The acetonitrile-aqueous solution(containing 0.1% formic acid) was adopted as the mobile phase for gradient elution. Seven components and internal standard(chlorogenic acid) were separated within 12 min. Mass spectrometric detection was performed in multiple reaction monitoring(MRM) mode using electrospray ionization(ESI) source with fast switching between positive and negative ions. The method was verified by specificity, linearity, precision, accuracy, recovery, matrix effect, and stability and met the requirements of pharmacokinetic study on the 7 components in rat plasma. Pharmacokinetic results showed that the average peak time(T_(max)) of the 7 components was 0.31-2.19 h, their elimination half-life(t_(1/2)) was 5.26-16.65 h, and the average residence time(MRT) was 6.29-31.03 h after the oral administration of the active fraction of Alpiniae Officinarum Rhizoma to rats with H. pylori gastritis. The plasma exposure levels of galangin and DHPA were higher than those of the other components. The concentration-time curves of four detected flavonoids showed obvious double peaks. This study elucidated the pharmacokinetic characteristics of 7 characteristic components from the active fraction of Alpiniae Officinarum Rhizoma in rats with H. pylori gastritis, providing a scientific basis for the identification of the pharmacodynamic substances of Alpiniae Officinarum Rhizoma for treatment of H. pylori gastritis and the clinical application of Alpiniae Officinarum Rhizoma in the prevention and treatment of H. pylori gastritis.
