ObjectiveThis paper aims to investigate and evaluate the staged efficacy and safety of the representative empirical prescription of the “Zhu Ke Jiao” theory, Qijia Rougan prescription, combined with entecavir in the treatment of hepatic fibrosis in chronic hepatitis B. MethodsA multicenter randomized controlled clinical study was conducted, and 101 patients diagnosed with chronic hepatitis B-related hepatic fibrosis (CHB-HF) who met the diagnosis and inclusion criteria were randomly assigned to an observation group (Qijia Rougan prescription + entecavir) and a control group (entecavir). The treatment duration was 24 weeks. Liver stiffness measurement (LSM), fibrosis-4 index (FIB-4), portal vein diameter, hepatitis B serology, biochemical indicators, hepatic fibrosis markers in serum [hyaluronic acid (HA), laminin (LN), procollagen Ⅲ peptide (PⅢP), and type Ⅳ collagen (Ⅳ-C)], and traditional Chinese medicine syndrome scores were used as efficacy evaluation indicators. Efficacy assessments and explorations of different staged subgroups of Qijia Rougan prescription were conducted according to LSM values based on the Metavir pathological staging standard. ResultsA total of 98 cases were included for statistical analysis, with 49 cases in the observation group and 49 in the control group. The general data of the patients in both groups were comparable. Compared with the same group before treatment, the observation group showed a significant reduction in LSM and FIB-4 (P<0.01), as well as notable improvements in LN, Ⅳ-C, and various TCM syndrome scores (P<0.05, P<0.01). When compared to the control group after treatment, the observation group demonstrated significant improvements in LSM, FIB-4, and various TCM syndrome score indicators (P<0.05, P<0.01), indicating that the observation group performed better than the control group. Subgroup analysis of the regression of hepatic fibrosis stages showed that compared to the same group before treatment, the observation group had better improvement in regression of stages F2 and F3 (P<0.05). When compared to the control group after treatment, the observation group exhibited superior improvement in regression of stage F3 (P<0.05). No adverse events occurred in either group during the treatment period. ConclusionCompared with entecavir alone, the combination of Qijia Rougan prescription and entecavir significantly improves the degree of hepatic fibrosis and clinical TCM symptoms in patients. The optimal intervention period is primarily during stage F3, which is a potential “interception” point of the “Zhu Ke Jiao” theory.

OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors (DTIs) in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital (the Affiliated Hospital of UESTC), a multidisciplinary working group was established. Through literature review and the Delphi method, clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework; systematic searches were conducted in CNKI, Medline, Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment,Development and Evaluation (GRADE) approach, and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations (each with an expert consensus rate exceeding 90%) on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection, dosing ranges, key monitoring points, and safety management strategies for parenteral DTIs in various scenarios, including the perioperative period of ventricular assist device implantation, the perioperative period of cardiac surgery, perioperative patients with lower-extremity atherosclerotic disease, the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome, the perioperative period of carotid artery stenting in patients with carotid stenosis, the perioperative period of patients with right heart thrombosis, and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition, warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus, which is formulated based on the best available evidence, provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

Prescription optimization is a crucial aspect in the study of traditional Chinese medicine (TCM) compounds. In recent years, the introduction of mathematical methods, data mining techniques, and artificial neural networks has provided new tools for elucidating the compatibility rules of TCM compounds. The study of TCM compounds involves numerous variables, including the proportions of different herbs, the specific extraction parts of each ingredient, and the interactions among multiple components. These factors together create a complex nonlinear dose-effect relationship. In this context, it is essential to identify methods that suit the characteristics of TCM compounds and can leverage their advantages for effective application in new drug development. This paper provided a comprehensive review of the cutting-edge optimization experimental design methods applied in recent studies of TCM compound compatibilities. The key technical issues, such as the optimization of source material selection, dosage optimization of compatible herbs, and multi-objective optimization indicators, were discussed. Furthermore, the evaluation methods for component effects were summarized during the optimization process, so as to provide scientific and practical foundations for innovative research in TCM and the development of new drugs based on TCM compounds.

ObjectiveBased on transcriptomics, to explore the mechanism of Hei Xiaoyaosan regulating the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway to improve the learning and memory ability of insomnia rats with liver depression syndrome. MethodsSixty 8-week-old male SD rats were randomly divided into the blank group, model group, eszopiclone group (0.09 mg·kg-1), and low, medium, and high dose groups of Hei Xiaoyaosan (3.82, 7.65, 15.30 g·kg-1), with ten rats in each group. Except for the blank group, the other groups were induced insomnia rat model with liver depression by chronic restraint, tail clamping stimulation and intraperitoneal injection of p-chlorophenylalanine (PCPA). Each treatment group received intragastric administration according to the specified dosage, once a day for 14 consecutive days. The pentobarbital sodium cooperative sleep test, open field test, and Morris water maze test were used to test the sleep quality, depressive-like behavior, and learning and memory abilities of rats. Additionally, enzyme-linked immunosorbent assay (ELISA) was used to detect the contents of 5-hydroxytryptamine (5-HT), γ-aminobutyric acid (GABA), brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF) and nitric oxide (NO) in hippocampus. Hematoxylin-eosin (HE) staining was performed to observe pathological changes of the hippocampal tissue, while terminal deoxynucleotidyl transferase deoxyuridine triphosphate (dUTP) nick end labeling (TUNEL) was used to evaluate apoptosis of hippocampal neurons. Transcriptomic sequencing technology was employed to identify differentially expressed genes in hippocampus between the model group and the blank group, as well as between the medium-dose group of Hei Xiaoyaosan and the model group. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were performed on the intersecting genes. Subsequently, the enriched key genes and signaling pathways were analyzed and verified. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was utilized to assess the mRNA expression levels of phosphatase and tensin homolog (PTEN), B-cell lymphoma-2 (Bcl-2)-like protein 11 (BCL2L11), and mitogen-activated protein kinase 1 (MAPK1) in hippocampus, and Western blot was employed to evaluate the protein expressions of PI3K, phosphorylation (p)-PI3K, Akt, p-Akt, Bcl-2, Bcl-2-associated X protein (Bax), and cleaved Caspase-3 in the same tissue. ResultsCompared with the blank group, the model group exhibited a reduction in body weight, an increase in sleep latency, and a decrease in sleep duration (P<0.01). Additionally, rats showed obvious depression-like behavior, and their learning and memory abilities decreased. Furthermore, the contents of 5-HT, GABA, NO, BDNF and GDNF in hippocampus decreased (P<0.01). Histological examination revealed a disorganized cell arrangement in the CA1 region of the hippocampus, characterized by irregular cell shapes, a reduced cell count, deeply stained and pyknotic nuclei, increased vacuolar degeneration, and an elevated apoptosis rate (P<0.01). Compared with the model group, the body weight of the high and medium dose groups of Hei Xiaoyaosan increased, the sleep latency shortened and the sleep time prolonged (P<0.05, P<0.01). Additionally, depression-like behavior and learning and memory abilities of rats were significantly improved, the levels of 5-HT, GABA, NO, BDNF and GDNF in the hippocampus increased (P<0.05, P<0.01). These interventions also ameliorated pathological damage in the hippocampal CA1 area and reduced the apoptosis of hippocampal neurons (P<0.01). Transcriptomic sequencing results indicated that Hei Xiaoyaosan might exert a therapeutic effect by regulating PI3K/Akt pathway through key mRNAs such as PTEN, BCL2L11, and MAPK1. The roles of these key mRNAs and proteins within PI3K/Akt pathway were further validated. In comparison to the blank group, the expression levels of PTEN, BCL2L11 and MAPK1 mRNA in the hippocampus of rats in the model group were increased (P<0.01), while the protein expression levels of p-PI3K, p-Akt and Bcl-2 were decreased (P<0.01), and the protein expression levels of PTEN, Bax and cleaved Caspase-3 were increased (P<0.01). Compared with the model group, the high-dose and medium-dose groups of Hei Xiaoyaosan could down-regulate the expressions of PTEN, BCL2L11 and MAPK1 mRNAs (P<0.01), up-regulate the expressions of p-PI3K, p-Akt and Bcl-2 proteins (P<0.01), and down-regulate the protein expressions of PTEN, Bax and cleaved Caspase-3 (P<0.05, P<0.01). ConclusionHei Xiaoyaosan may regulate PI3K/Akt signaling pathway by down-regulating expressions of key genes such as PTEN, BCL2L11 and MAPK1, and thus improve the learning and memory abilities of insomnia rats with liver depression syndrome.

ObjectiveTo explore the mechanism of the Wenyang Jieyu prescription in regulating depression-like behavior in mice after maternal-infant separation combined with secondary stress. MethodsAfter birth, the rats were randomly divided into blank (NC) group, maternal-infant separation (MS) group, restraint stress (RS) group, maternal-infant separation combined with restraint stress (MRS) group, Wenyang group, Jieyu group, Wenyang Jieyu (XSF) group, and minocycline group. Maternal-infant separation was performed on day 5 (PD5), followed by weaning at PD21 and prophylactic administration. The dose of Wenyang group, Xiaoyao group, XSF group and minocycline group were 5.85, 12.03, 16.71 g·kg-1 and 50 mg·kg-1, respectively. Restraint stress was applied on PD90. The model was evaluated using glucose, social interaction, open field, and O-maze behavior tests, as well as high-performance liquid chromatography to measure serotonin, dopamine, and other neurotransmitters. The expression level of ionized calcium-binding adaptor molecule-1 (Iba-1) protein, a marker of hippocampal microglia, was detected by immunohistochemistry. Protein expression levels of Janus kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3) in the hippocampus were analyzed by an automatic protein expression analysis system. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect mRNA expression levels of M1 markers, JAK2/STAT3 pathway-related genes, and cytokines in hippocampal microglia in each group. ResultsCompared with the NC group, the MRS group exhibited depression-like behavior, with significantly decreased levels of neurotransmitters in the hippocampus (P<0.05, P<0.01), increased expression of Iba-1 (P<0.01), and elevated protein levels of JAK2 and STAT3 (P<0.05). The mRNA expression levels of CD68, CD11b, IL-1β, JAK2, and STAT3 were significantly increased (P<0.01), while IL-10 mRNA expression was significantly decreased (P<0.01). Compared with the MRS group, the XSF and minocycline groups showed some improvement in depression-like behavior. In these groups, the hippocampal neurotransmitter content was significantly increased (P<0.05, P<0.01), and Iba-1 expression was significantly decreased (P<0.01). The protein levels of JAK2 and STAT3 in the XSF group showed a downward trend. The mRNA expression levels of CD68, CD11b, JAK2, STAT3, and IL-1β in the hippocampus were significantly decreased in the XSF and minocycline groups (P<0.05, P<0.01), while IL-10 mRNA expression was significantly increased (P<0.05, P<0.01). ConclusionWenyang Jieyu prescription can regulate depression-like behavior in maternal-infant separation mice combined with secondary stress by inhibiting the polarization of hippocampal microglia to the M1 phenotype. The regulation of hippocampal microglia polarization by Wenyang Jieyu prescription may be associated with the JAK2/STAT3 pathway.

The holistic view is the key in the study of traditional Chinese medicine(TCM). The component structure theory is based on the holistic view to investigate the correlation between material basis and efficiency, which enriches the holistic "component-effect" research of TCM. Gintonin is a newly isolated non-saponin component of ginseng. Compared to ginsenosides, gintonin has many different pharmacological activities, and it provides new knowledge for the holistic research of ginseng. Thus, taking the discovery of gintonin from ginseng as an example, this paper explored the linkage between ginsenosides and gintonin from the perspective of "component-effect" correlations and systematically sorted out the similarities and differences between them in terms of structural characteristics, modes of action, and pharmacological activities. Starting from the collaborative interaction of TCM compounds, the study discussed the application and value of the holistic view in TCM "component-effect" research in the light of the component structure theory to provide new thoughts for the development of modern TCM research.

Yinyang Gongji Pills have the effects of strengthening the body resistance to eliminate pathogenic factors, removing stasis, and reducing swelling, which is a commonly used traditional Chinese medicine(TCM) formula for treating intestinal accumulation. A real-world, registered, and single-arm clinical trial was conducted to observe the clinical efficacy and safety of Yinyang Gongji Pills combined with capecitabine in the treatment of advanced colorectal cancer and analyze the clinical characteristics of the patients. A total of 60 patients with advanced colorectal cancer who refused or could not tolerate standard treatment of western medicine were included in the study. They were treated with Yinyang Gongji Pills combined with capecitabine until disease progression or intolerable adverse events occurred. The main observation indicators were progression-free survival(PFS) and safety. The treatment effects of the patients under different baseline characteristics were analyzed. The clinical trial has found that the median PFS of all enrolled patients was 7.3 months, with 30.1% of patients having a PFS exceeding 12.0 months. Layered analysis showed that the median PFS of patients with the onset site being the colon and rectum were respectively 8.4 and 4.7 months. The median PFS of patients with high, medium, and low tumor burden were respectively 7.0, 4.7, and 10.8 months. The median PFS of patients with wild-type and mutant-type RAS/BRAF were respectively 7.9 and 6.9 months. The median PFS of patients with KPS scores ≥80 and ≤70 were respectively 7.9 and 6.5 months. The median PFS of patients treated with Yinyang Gongji Pills for ≥6, 3-6, and ≤3 months were respectively 8.0, 5.2, and 4.2 months. The median PFS of patients with spleen, kidney, liver, and lung syndrome differentiation in TCM were respectively 8.3, 6.7, 7.3, and 5.6 months. The median PFS of patients with TCM pathological factors including phlegm, dampness, and blood stasis were respectively 7.0, 7.3, and 6.5 months. Common adverse reactions include anemia, decreased white blood cells, decreased appetite, fatigue, and hand foot syndrome, with incidence rates being respectively 44.2%, 34.6%, 42.3%, 32.7%, and 17.3%. The results showed that the combination of Yinyang Gongji Pills and capecitabine demonstrated potential clinical efficacy and good safety in this study. The patients have clinical characteristics such as low tumor burden, onset site at the colon, KPS scores ≥ 80, long duration of oral TCM, and TCM syndrome differentiation including spleen or liver.

Emodin is a hydroxyanthraquinone compound that is widely distributed and has multiple pharmacological activities, including anti-diarrheal, anti-inflammatory, and liver-protective effects. Research indicates that emodin may be one of the main components responsible for inducing hepatotoxicity. However, studies on the mechanisms of liver injury are relatively limited, particularly those related to bile acids(BAs) metabolism. This study aims to systematically investigate the effects of different dosages of emodin on BAs metabolism, providing a basis for the safe clinical use of traditional Chinese medicine(TCM)containing emodin. First, this study evaluated the safety of repeated administration of different dosages of emodin over a 5-week period, with a particular focus on its impact on the liver. Next, the composition and content of BAs in serum and liver were analyzed. Subsequently, qRT-PCR was used to detect the mRNA expression of nuclear receptors and transporters related to BAs metabolism. The results showed that 1 g·kg~(-1) emodin induced hepatic damage, with bile duct hyperplasia as the primary pathological manifestation. It significantly increased the levels of various BAs in the serum and primary BAs(including taurine-conjugated and free BAs) in the liver. Additionally, it downregulated the mRNA expression of farnesoid X receptor(FXR), retinoid X receptor(RXR), and sodium taurocholate cotransporting polypeptide(NTCP), and upregulated the mRNA expression of cholesterol 7α-hydroxylase(CYP7A1) in the liver. Although 0.01 g·kg~(-1) and 0.03 g·kg~(-1) emodin did not induce obvious liver injury, they significantly increased the level of taurine-conjugated BAs in the liver, suggesting a potential interference with BAs homeostasis. In conclusion, 1 g·kg~(-1) emodin may promote the production of primary BAs in the liver by affecting the FXR-RXR-CYP7A1 pathway, inhibit NTCP expression, and reduce BA reabsorption in the liver, resulting in BA accumulation in the peripheral blood. This disruption of BA homeostasis leads to liver injury. Even doses of emodin close to the clinical dose can also have a certain effect on the homeostasis of BAs. Therefore, when using traditional Chinese medicine or formulas containing emodin in clinical practice, it is necessary to regularly monitor liver function indicators and closely monitor the risk of drug-induced liver injury.

BACKGROUND AND OBJECTIVE: Patients with glioma experience a high symptom burden and have diverse palliative care needs. However, the assessment scales used in palliative care remain non-standardized and highly heterogeneous. To evaluate the application patterns of the current scales used in palliative care for glioma, we aim to identify gaps and assess the need for disease-specific scales in glioma palliative care. METHODS: We conducted a systematic search of five databases including PubMed, Web of Science, Medline, EMBASE, and CINAHL for quantitative studies that reported scale-based assessments in glioma palliative care. We extracted data on scale characteristics, domains, frequency, and psychometric properties. Quality assessments were performed using the Cochrane ROB 2.0 and ROBINS-I tools. RESULTS: Of the 3,405 records initially identified, 72 studies were included. These studies contained 75 distinct scales that were used 193 times. Mood (21.7%), quality of life (24.4%), and supportive care needs (5.2%) assessments were the most frequently assessed items, exceeding half of all scale applications. Among the various assessment dimensions, the Distress Thermometer (DT) was the most frequently used tool for assessing mood, while the Short Form-36 Health Survey Questionnaire (SF-36) was the most frequently used tool for assessing quality of life. The Mini Mental Status Examination (MMSE) was the most common tool for cognitive assessment. Performance status (5.2%) and social support (6.8%) were underrepresented. Only three brain tumor-specific scales were identified. Caregiver-focused scales were limited and predominantly burden-oriented. CONCLUSIONS: There are significant heterogeneity, domain imbalances, and validation gaps in the current use of assessment scales for patients with glioma receiving palliative care. The scale selected for use should be comprehensive and user-friendly.

OBJECTIVE:
To investigate the effect of the sequence of intermediate instrumentation and distraction-reduction of the injured vertebra on the surgical efficacy of short-segment percutaneous pedicle screw fixation for thoracolumbar burst fractures with high rate of spinal canal encroachment.
METHODS:
From January 2016 to January 2022, 38 patients with thoracolumbar burst fractures with high rate of spinal canal encroachment (spinal canal encroachment rate >40%, complete posterior longitudinal ligament, no flipping bone block in the posterior marginal of the vertebra) without spinal cord injury who were were treated with short-segment percutaneous pedicle screw fixation were retrospectively analyzed. During the operation, 18 cases were used distraction-reduction first and then intermediate instrumentation on injured vertebral and sequential distraction-reduction again(the distraction-reduction first group) including 8 females and 10 males with a mean age of 46.5 (38.5, 50.0) years old, and the other 20 cases were used intermediate instrumentation on injured vertebral first and then direct distraction-reduction(the intermediate instrumentation first group) including 10 males and 10 females with a mean age of 46.0 (35.8, 50.8) years. The anterior height ratio of the injured vertebra, local Cobb's angle of the injured vertebrae, the spinal canal encroachment rate, and the improvement rate of spinal canal encroachment were compared and evaluated.
RESULTS:
All patients were followed up for more than 1 year, and no complications such as spinal cord and root injury, screw loosening and screw rod fracture were found. The anterior height ratio of the injured vertebra, local Cobb' angle of the injured vertebra in the two groups were significantly improved compared with preoperative data(P<0.05), and those at 3 months and 1 year after operation was lost compared with that at the previous time point(P<0.05). Although the spinal canal encroachment rate of the two groups 1 day and 1 year after operation was improved compared with that before operation(P<0.05), the improvement of spinal canal volume in the distraction-reduction first group was significantly better than that in the intermediate instrumentation first group (P<0.01).
CONCLUSION
In the treatment of patients with thoracolumbar fractures with high rate of spinal canal encroachment, short-segment percutaneous pedicle screw internal fixation with distraction-reduction first and then intermediate instrumentation and sequential distraction-reduction again can more effectively reduce the bony encroachment in the spinal canal and achieve indirect decompression effect better.
