By consulting ancient and modern literature, this article systematically reviews and verifies the historical evolution of the herbal medicine known as Baijiang across various dimensions, including name, origin, scientific name verification, medicinal parts, production area, quality, harvesting and processing, as well as its nature, taste, and therapeutic effects, in order to provide a reference for the development and utilization of famous classical formulas containing Patriniae Herba. Patriniae Herba has a long history of use. It derives its name from the distinctive musty odor of its roots, which resembles spoiled soy sauce. However, due to its alias Kucai, there has been much confusion with other plants. Since the Ming dynasty, various plants have been used interchangeably as Baijiang. Herbal textual research showed that Patriniae Herba was first recorded in Shennong Bencaojing, and throughout history, Baijiang has been recognized as its standard name, though it has also been known by alternative names such as Luchang, Lujiang, and Suanyi. The main sources used throughout the ages were Patrinia scabiosaefolia or P. villosa, which is consistent with the 1977 edition of the Pharmacopoeia of the People's Republic of China. However, while the roots were traditionally used medicinally, the whole plant is now more commonly used in modern practice. In addition, the whole plants of Thlaspi arvense from the Cruciferae family and Sonchus brachyotus from the Compositae family are commonly used as regional substitutes for Baijiang. According to ancient records, Patriniae Herba was primarily found in Jiangxia(present-day eastern Hubei province) and Jiangdong(the region south of the lower reaches of the Yangtze River), but modern literature shows that it is distributed throughout the country without a distinct geographical origin. In ancient times, the roots were harvested in August and sun-dried, today, the whole plant is typically dug up in summer or autumn and sun-dried. In recent times, the quality has been summarized as being best when the roots are long, the leaves are abundant and green, and the aroma is strong. Regarding the processing, ancient methods often involved baking(drying over fire), while modern methods typically involve removing impurities, washing, and then cutting and drying the segments. The effects of Patriniae Herba are to clear heat and detoxify, eliminate blood stasis and drain pus. During the Han and Northern and Southern dynasties, it was used to treat skin diseases caused by heat, abscesses, postpartum diseases, and rheumatism, during the Five dynasties period, its therapeutic applications expanded to include diseases of the five senses, and by the modern era, conditions such as neurasthenia and insomnia were added. Regarding its properties and taste, it was recorded as bitter and neutral during the Han dynasty. By the Tang dynasty, it was slightly cold, with a taste of acrid and bitter. During the Yuan and Ming dynasties, it was mostly slightly cold and neutral, with a bitter and salty taste. In the Qing dynasty and modern times, it was mostly bitter and neutral, and in contemporary times, it has evolved to a taste of acrid, bitter, and cool. Based on the results of this study, it is recommended that when developing and utilizing famous classical formulas containing Patriniae Herba, one should select the entire herb of the historically mainstream sources, P. scabiosaefolia or P. villosa from the Valerianaceae family, and choose the processing method according to the prescription requirements. It is recommended to use raw products without specific requirements.

Background/Aims:
Liver transplantation (LT) following total hepatectomy is a life-saving treatment for hepatocellular carcinoma (HCC). The HCC recurrence after LT hinders the effectiveness of the procedure. The objective of this study is to develop a pre-operative risk stratification model based on a liquid biopsy.
Methods:
We conducted a comprehensive multi-omics study of 260 HCC patients from three centers, including clinical data, low-coverage whole-genome sequencing of cell-free DNA (cfDNA) from plasma, as well as whole-exome, single-nucleus RNA, and spatial transcriptomics from matched tumor and non-tumor tissues.
Results:
We identified cfDNA-derived copy number alteration (CNA) signatures associated with post-transplant recurrence. By integrating cfDNA-derived CNA profiles with single-cell transcriptomic data, we traced recurrence-associated cfDNA to a distinct subpopulation of malignant cells within the primary tumor. These cells were embedded in a pro-metastatic microenvironment of specialized endothelial subtypes and cancer-associated fibroblasts. Notably, most recurrence-associated lesions were detectable in cfDNA prior to liver transplantation (LT). Building on these insights, we developed the ZJU Criteria based on CNA fragments and tumor markers, a pre-LT risk prediction tool that integrates conventional clinical factors with cfDNA-derived CNA signatures, and validated it using internal and independent external cohorts.
Conclusion
Our findings suggest that post-transplant recurrence commonly originates from advanced subclones that emerge late during tumor evolution. The ZJU Criteria provides an accurate, non-invasive strategy that significantly improves pre-LT risk stratification and clinical decision-making for patients with HCC.

Objective To investigate the post-discharge exercise behavior and factors influencing moderate to vigorous intensity physical activity (MVPA) in patients undergoing lung surgery. Methods A total of 2874 patients from the large prospective, observational perioperative lung symptom study cohort (CN-PRO-Lung 3) in the Department of Thoracic Surgery at Sichuan Cancer Hospital between April 7, 2021, and January 31, 2024, were selected as the survey subjects. A survey was conducted using the Investigation of Exercise Behavior after Lung Surgery questionnaire and the International Physical Activity Questionnaire-Short Form (IPAQ-SF) among patients who underwent lung surgery. Binary logistic regression was used to analyze the factors influencing patients’ engagement in MVPA. Results A total of 702 patients were surveyed, including 252 males and 450 females, with an average age of (52.4±10.2) years. Patients with lung cancer accounted for 85.9%. Only 36.0% of the patients had regular exercise habits, while 42.3% did not engage in any physical activity. The three main barriers for postoperative exercise were physical discomfort (pain, coughing, shortness of breath, etc, 54.7%), lack of professional guidance (41.7%), and concerns about the surgical wound (28.9%). The proportions of patients engaging in vigorous, moderate, and low-intensity physical activity were 5.7%, 28.2%, and 66.1%, respectively. Multivariate analysis showed that patients with a personal annual income ≥50000 yuan (OR=1.52, 95%CI 1.01-2.29, P=0.044), high school education or above (OR=1.92, 95%CI 1.33-2.76, P<0.001), and lobectomy (OR=1.44, 95%CI 1.02-2.03, P=0.037) engaged in more MVPA. Conclusion Patients undergoing lung surgery have inadequate physical activity after discharge, particularly lacking in MVPA. Patients with higher income, higher educational levels, and lobectomy are more frequently engaged in MVPA. Measures such as symptom control, providing exercise guidance, and enhancing education on wound care may potentially improve the inadequate physical activity in lung surgery patients after discharge.

ObjectiveTo explore the therapeutic effect and mechanism of Huangqi Xiayuxue decoction against hepatocellular carcinoma based on network pharmacology, animal experiments, and cell experiments. MethodsThe active ingredients and corresponding targets of Huangqi Xiayuxue decoction were screened via databases including the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine (BATMAN-TCM). Hepatocellular carcinoma-related targets were retrieved from the GeneCards database. The common targets shared by Huangqi Xiayuxue decoction and hepatocellular carcinoma were subjected to Gene Ontology (GO) functional annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Huangqi Xiayuxue decoction-containing plasma was prepared. The cell counting kit-8 (CCK-8) assay was adopted to observe the effects of different volume fractions (5%, 10%, 15%, and 20%) of Huangqi Xiayuxue decoction-containing plasma on the proliferation of HepG2, MHCC-97H, Hepa1-6, and Huh-7 cells, and the concentration for subsequent experiments was determined. Flow cytometry was adopted to detect the effects of Huangqi Xiayuxue decoction-containing plasma (5%, 10%, 15%, and 20%) on the apoptosis of MHCC-97H cells. A mouse model of subcutaneous xenograft hepatocellular carcinoma was established. The model mice were assigned into low-, medium-, and high-dose (4.63, 9.25, 18.5 g·kg-1) Huangqi Xiayuxue decoction and sorafenib (20 mg·kg-1) groups. Body mass and tumor volume of mice were dynamically monitored during the intervention period. After 3 weeks of intervention, hematoxylin-eosin (HE) staining was performed to observe tumor morphology. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay was employed to detect cell apoptosis. Immunohistochemistry (IHC) was adopted to examine the expression of cysteinyl aspartate-specific proteinase-3 (Caspase-3), B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax) in the tumor tissue. Real-time PCR and Western blot were employed to verify the changes in apoptosis-related factors and the phosphatidylinositol 3-kinase/protein kinase B/forkhead box O1 (PI3K/Akt/FoxO1) signaling pathway. ResultsA total of 220 common targets shared by Huangqi Xiayuxue decoction and hepatocellular carcinoma were screened out by network pharmacology, among which tumor protein p53 (TP53), Akt1, and signal transducer and activator of transcription 3 (STAT3) were the core targets. Pathway enrichment analysis indicated that the common targets were involved in cell apoptosis and proliferation, as well as the PI3K/Akt and FoxO signaling pathways. Cell experiments showed that compared with the blank plasma group, all volume fractions of Huangqi Xiayuxue decoction-containing plasma inhibited the proliferation of HepG2, MHCC-97H, Hepa1-6, and Huh-7 cells (P<0.01). The proportion of early apoptotic cells in MHCC-97H cells was increased after treatment with different volume fractions of Huangqi Xiayuxue decoction-containing plasma (P<0.01). Animal experiments revealed that Huangqi Xiayuxue decoction inhibited the growth of tumor volume, promoted tumor cell apoptosis in the high-dose group, up-regulated the protein and mRNA levels of Bax and Caspase-3, down-regulated the protein and mRNA levels of Bcl-2, and reduced the phosphorylation level of the PI3K/Akt/FoxO1 signaling pathway (P<0.05, P<0.01). ConclusionHuangqi Xiayuxue decoction exerts anti-hepatocellular carcinoma effects by inhibiting the activation of the PI3K/Akt/FoxO1 signaling pathway and promoting hepatocellular carcinoma cell apoptosis.

As a common medical condition, vertigo can be induced by multiple diseases in the modern medical system. Its incidence rate shows an upward trend with the increase in age. According to the theory of mutual interference between clear Qi and turbid Qi in Huangdi's Internal Classic (Huang Di Nei Jing), this paper systematically analyzes the pathogenesis of vertigo and explores the mechanism and clinical application value of Xiao Chaihutang in the treatment of vertigo. It is believed that the mutual inference between clear Qi and turbid Qi leads to the failure of clear Yang to ascend, resulting in the lack of nourishment for the brain and the inability of turbid Yin to descend, which disturbs the clear orifices, thus causing vertigo. The core pathogenesis lies in the dysfunction of Qi movement, the disorder of body fluid distribution, and the imbalance between Yin and Yang. The compatibility of Xiao Chaihutang takes into account the methods of pungent medicinal materials opening and bitter medicinal materials descending, tonifying deficiency and purging excess, and regulating Qi movement. This prescription can regulate the pathological state of the mutual interference between clear Qi and turbid Qi from three aspects: regulating Qi movement throughout the body, harmonizing the distribution of body fluids, and coordinating Yin and Yang as well as the interior and exterior, thus preventing and treating vertigo. Modern research findings show that Xiao Chaihutang can improve hemodynamics to promote cerebral blood circulation and has anti-inflammation, immunomodulatory, and anti-tumor functions, which correspond to the therapeutic effects of Xiao Chaihutang under the theory of mutual interference between clear Qi and turbid Qi. The decoction exerts therapeutic effects on vertigo caused by hypertension, stroke, otitis media, Meniere’s disease, and brain tumor as well as benign paroxysmal positional vertigo. Further exploration of the theoretical connotation of mutual inference between clear Qi and turbid Qi and analysis of the pathogenesis of vertigo and the therapeutic effect of Xiao Chaihutang can better interpret the internal correlations among the three, thus providing new ideas for the syndrome differentiation and treatment of vertigo.

In order to clarify the effects of drought stress training on the quality and drought resistance of Codonopsis pilosula, this study used PEG to simulate drought stress and employed potting with water control for the drought stress training of C. pilosula plants. The polysaccharide content, secondary metabolites, antioxidant system, and photosynthetic pigment system of C. pilosula after drought stress training were analyzed. The results showed that the content of fructans in the root of C. pilosula increased after two rounds of drought stress treatment, and it was significantly higher than that of the control group. The accumulation of fructans in the root of C. pilosula showed an upward trend during the rehydration treatment. The content of lobetyolin and tangshenoside Ⅰ increased after drought stress treatment compared with that of the control group. The rehydration treatment caused first increasing and then decreasing in the content of lobetyolin, while it had no significant effect on the tangshenoside Ⅰcontent. The content of photosynthetic pigments decreased after drought stress treatment, and it gradually increased during the first round of rehydration and the second round of rehydration. Moreover, the increase was faster in the second round of rehydration than in the first round of rehydration. The content of the peroxidation product malondialdehyde(MDA) and the activities of superoxide dismutase(SOD), peroxidase(POD), and catalase(CAT) increased after drought stress treatment compared with those of the control group, and they showed a tendency of decreasing during rehydration. Moreover, the decrease was faster in the second round of rehydration than in the first round of rehydration. When the plants of C. pilosula after drought stress training were again subjected to severe drought stress, the wilting rate decreased significantly, and the biomass increases significantly. This study showed that the drought stress training could promote the accumulation of polysaccharides and secondary metabolites in the root of C. pilosula. When encountering drought stress again, C. pilosula plants could quickly regulate the antioxidant system and delay the decomposition of chlorophyll to respond to drought stress. The findings provide a theoretical basis for the ecological cultivation of C. pilosula in arid and semi-arid areas.

To clarify the occurrence and distribution of broad bean wilt virus 2(BBWV2) on Rehmannia glutinosa, this study collected 87 R. glutinosa samples with typical symptoms of viral disease such as chlorosis and crumple from Wenxian county and Wuzhi county in Jiaozuo city, Henan province and Qiaocheng district in Bozhou city, Anhui province. The BBWV2 CP target band was amplified from 37 R. glutinosa samples by RT-PCR technology. The total detection rate reached 42.5%, among which 43.0% was detected in samples from Henan province. The detection rate in samples from Anhui province was 37.5%. 37 BBWV2 CP sequences were obtained by cloning and sequencing of BBWV2 positive samples(data has been submitted to GenBank, accession numbers: PP407959-PP407995), and the sequence analysis of these CP sequences with 91 other BBWV2 isolates in GenBank showed a high genetic diversity with a consistency rate of 70.8%-100%. Meanwhile, phylogenetic analysis showed that BBWV2 could be divided into three groups according to CP sequences, among which the BBWV2 in R. glutinosa isolates obtained in this study were all located in group 3. This study identified the differences in the occurrence, distribution, and genetic diversity of BBWV2 in R. glutinosa from Henan province and Anhui province and provided a theoretical basis for the prevention and control of BBWV2.
