ObjectiveTo systematically compare the differential regulation of the maternal-fetal interface cell lineages and communication networks in the CBA/J×DBA/2 mouse model of recurrent pregnancy loss (RPL) by the two classic therapeutic methods-tonifying the kidney to stabilize the fetus and invigorating the spleen to stabilize the fetus (Shoutai Wan, Juyuan Jian)-of traditional Chinese medicine (TCM) at the single-cell resolution and clarify their modern scientific connotations. MethodsFemale non-pregnant CBA/J mice were caged with male BALB/c (blank group) and DBA/2 (modeling group) mice separately. Pregnant mice in the modeling group were randomly grouped as follows: high/low-dose Shoutai Wan, high/low-dose Juyuan Jian, model (RPL), and positive control (dydrogesterone), with 10 mice in each group. Starting from the day after the detection of the vaginal plug, mice were administrated with drugs or an equal volume of normal saline by gavage for 10 consecutive days. After the intervention, the following indicators were measured. ① Macroscopic evaluation: general conditions, uterine wet weight, embryo loss rate, four coagulation parameters [prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), and thrombin time (TT)], and peripheral blood estradiol (E2) and progesterone (Pg) levels. The decidua with embryos was stained with hematoxylin-eosin (HE) and evaluated by transmission electron microscopy (TEM). The expression of B-cell lymphoma-2 (Bcl-2), vascular endothelial growth factor (VEGF), angiotensin Ⅱ (AngⅡ), matrix metalloproteinase-2 (MMP-2), interleukin-6 (IL-6), leukemia inhibitory factor (LIF), CXC chemokine ligand 12 (CXCL12), and microtubule-associated protein 1 light chain 3 homolog (LC3)Ⅰ/Ⅱ was quantified by Western blot. ② Mechanism analysis at the single-cell level: The decidua with embryos from the blank, model, high-dose Shoutai Wan, and high-dose Juyuan Jian groups (6 mice per group, with 3 single-cell samples per group, totaling 24 mice) were analyzed by the BD Rhapsody™ platform, and the whole-cell atlas was drawn by uniform manifold approximation and projection (UMAP) dimensionality reduction clustering combined with the single-cell mouse cell atlas (scMCA). The differentially expressed genes (DEGs) and cell interaction networks were analyzed via Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and CellChat, and the protein-protein interaction (PPI) map of subtype cells was constructed. The CytoTRACE pseudo-temporal analysis was performed to explore the developmental trajectories of core immune cells (natural killer cells, NK cells) from maternal and fetal sources. Results① Pathological and Western blot results indicated that compared with the blank group, the RPL group showed an increase in the embryo loss rate (P<0.01), down-regulated expression of Bcl-2, LIF, MMP-2, and Vegf in the decidua with embryos (P<0.05), up-regulated protein levels of CXCL-12, AngⅡ, and IL-6 (P<0.05), blocked angiogenesis, apoptosis-inflammation imbalance, and coagulation dysfunction. Both prescriptions dose-dependently reduced the abortion rate and restored the angiogenesis-inflammation balance, and Shoutai pill showed superior performance in restoring the E2 level to the Pg level (P<0.05). ② Single-cell transcriptome analysis indicated that compared with the blank group, the RPL group showed differences in multiple key cell populations such as decidual cells, trophoblast cells, endothelial cells, erythroblasts, NK cells, and macrophages at the maternal-fetal interface. Immunity and angiogenesis were the key links in RPL. Compared with the RPL group, high-dose Shoutai Wan reversed the changes of NK cells in the embryonic layer (upregulating the mRNA levels of 17 genes and downregulating the mRNA levels of 29 genes) and macrophages (upregulating the mRNA levels of 117 genes and downregulating the mRNA levels of 53 genes) through the regulation of gene expression. High-dose Shoutai pill regulated the immune cells to affect unfolded proteins, cell adhesion, and programmed cell death, thereby promoting decidualization and angiogenesis and modulating embryo-membrane development. High-dose Juyuan Jian regulated the key subgroups of NK cells (up-regulating the mRNA levels of 9 genes and down-regulating the mRNA levels of 17 genes) and macrophages (up-regulating the mRNA levels of 110 genes and down-regulating the mRNA levels of 81 genes), which affected decidual inflammation and apoptosis and intervened in glycolysis. ③ The pseudo-temporal analysis and communication network indicated that the communication frequency of the RPL group decreased. High-dose Shoutai Wan restored maternal-fetal tolerance through pathways such as NKG2D, CDH5, GDF, and FASLG. High-dose Juyuan Jian enhanced the IL-6/LIFR/JAK/signal transducer and activator of transcription 3 (STAT3) and desmosome/SEMA6/tumor necrosis factor-like weak inducer of apoptosis (TWEAK) signaling to improve endometrial receptivity. The RPL group showed an increased proportion of toxic dNK7, a decreased proportion of reparative dNK4, and blocked embryo fNK1. High-dose Shoutai Wan down-regulated dNK7 and up-regulated dNK4. High-dose Juyuan Jian inhibited the terminal differentiation of dNK7 and up-regulated LILRB1, thus restoring the balance of cytotoxicity and repair. ConclusionBoth the kidney-tonifying and spleen-invigorating methods are effective in treating RPL. NK and macrophages are the key immune cells in the interaction between the embryo and the membrane. The kidney-tonifying method (Shoutai Wan) has an advantage in regulating the phenotypes of unfolded protein, cell adhesion, and programmed cell death, and shows expression characteristics closer to the physiological state in the regulation of NKG2D and CDH5 signals. The spleen-invigorating method (Juyuan Jian) has an advantage in regulating epithelial-mesenchymal transition (EMT), angiogenesis, and glycolysis and shows higher communication intensity in the IL-6 and LIFR pathways.

Guishenwan (GSW), originating from Jingyue Quanshu (Zhang Jingyue's Complete Works), is a classic traditional Chinese medicine (TCM) formula with a history of over 400 years. Designed for kidney essence deficiency syndrome, it is clinically applied to treat diseases associated with essence-blood deficiency, such as ovarian insufficiency diseases in women, oligospermia-induced infertility in men, and lumbar disc herniation. Numerous studies have confirmed its significant efficacy and advantages in managing ovarian insufficiency diseases, including diminished ovarian reserve (DOR), premature ovarian insufficiency (POI), and premature ovarian failure (POF). According to recent literature, the therapeutic mechanisms of GSW in treating ovarian insufficiency diseases involve regulating the hypothalamic-pituitary-ovarian axis (HPOA) function, ameliorating reproductive endocrine disorders, improving ovarian function, modulating relevant signaling pathways, and exerting immunoregulatory and anti-inflammatory effects. A review of GSW in clinical treatment revealed that clinical applications of GSW, particularly in combination with Western medicine, not only alleviate symptoms but also compensate for the limitations of hormone replacement therapy, thereby reducing recurrence, minimizing adverse reactions, and enhancing safety. This review aims to provide a scientific basis for the rational clinical use of GSW in ovarian insufficiency diseases, offer innovative TCM strategies for developing novel ovarian-protective drugs, promote the integration of TCM and Western medicine in reproductive medicine, and ultimately contribute a Chinese approach to global management of ovarian insufficiency diseases.

ObjectiveTo explore the efficacy and mechanisms of Sini San in the treatment of depression and liver injury based on gut microbiota. MethodsThirty-two male Sprague-Dawley (SD) rats were randomly divided into a normal group, model group (M), Sini San group (MS, 2.5 g·kg-1), and fluoxetine group (MF, 2 mg·kg-1). Except for the normal group, rats in the other three groups were subjected to chronic unpredictable mild stress (CUMS). After 8 weeks, the open-field test and sucrose preference test were conducted. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum corticosterone (CORT), adrenocorticotropic hormone (ACTH), corticotropin-releasing factor (CRF), lipopolysaccharide (LPS), Zonulin, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), γ-aminobutyric acid (GABA) levels in the hippocampus and prefrontal cortex, and brain-derived neurotrophic factor (BDNF) levels in the hippocampus. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect hippocampal BDNF mRNA expression. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were measured using the ultraviolet lactate dehydrogenase method. The ultrastructure of the intestinal epithelium was observed by electron microscopy, and gut microbiota in rat feces were analyzed using 16S rDNA high-throughput sequencing. ResultsCompared with the normal group, the sucrose preference of rats in the model group was significantly reduced (P0.01), whereas it was significantly increased in the Sini San group compared with the model group (P0.05). Compared with the normal group, hippocampal GABA protein levels and BDNF mRNA expression in the model group were significantly decreased (P0.05), and compared with the model group, both were significantly increased in the Sini San group (P0.05, P0.01). Compared with the normal group, serum LPS and Zonulin levels in the model group were significantly increased (P0.05, P0.01), and compared with the model group, Zonulin levels in the Sini San group were significantly decreased (P0.05). No obvious changes were observed in the ultrastructure of the jejunal mucosa among groups. Compared with the normal group, widened and blurred tight junctions, sparse and shortened microvilli, and mitochondrial swelling with cristae disruption in epithelial cells were observed in the ileal and colonic mucosa of the model group, which were markedly improved in the Sini San and fluoxetine groups. The results of 16S rDNA high-throughput sequencing showed that Sini San improved CUMS-induced dysbiosis of Bacteroidetes and Proteobacteria. Correlation analysis indicated that Bacteroidetes and Proteobacteria were significantly correlated with depression-related indicators, liver function, and intestinal mucosal permeability. ConclusionSini San exerts antidepressant and hepatoprotective effects by improving Bacteroidetes and Proteobacteria and inhibiting the increase in intestinal mucosal permeability in CUMS rats.

This paper systematically reviews the core concepts and lines of theoretical inheritance of major spleen-stomach theories in traditional Chinese medicine (TCM), including spleen deficiency theory, spleen-stomach damp-heat theory, and liver-spleen disharmony theory. It is found that these theories have all undergone a developmental trajectory characterized by classical foundation, refinement of therapeutic methods, systematization of pathogenesis, and modern innovation. The evolution of spleen-stomach theory has achieved a shift from a singular focus on tonifying the spleen to regulating dynamic middle-jiao (焦) balance, and from localized spleen-stomach regulation to the circular movement of qi involving all five zang organs. In terms of modern disease-syndrome integrative research, spleen deficiency syndrome is shown to be closely associated with impairment of the gastrointestinal mucosal barrier, metabolic disorders, and gene polymorphisms related to Helicobacter pylori-associated gastric diseases. Spleen-stomach damp-heat syndrome is closely linked to hyperactive energy metabolism, inflammatory cytokines, and abnormal expression of aquaporins. Liver-spleen disharmony syndrome is mainly associated with dysregulation of the brain-gut axis and microbiota-related metabolic disorders. It is proposed that future research on spleen-stomach diseases and syndromes should further elucidate their potential multidimensional differential biological characteristics, thereby promoting the modernization of the TCM discipline of spleen-stomach studies.

This paper outlines the development of artificial intelligence (AI) and its applications in traditional Chinese medicine (TCM) research, and elucidates the roles and advantages of large language models, knowledge graphs, and natural language processing in advancing syndrome identification, prescription generation, and mechanism exploration. Using spleen-stomach diseases as an example, it demonstrates the empowering effects of AI in classical literature mining, precise clinical syndrome differentiation, efficacy and safety prediction, and intelligent education, highlighting an upgraded research paradigm that evolves from data-driven and knowledge-driven approaches to intelligence-driven models. To address challenges related to privacy protection and regulatory compliance in cross-institutional data collaboration, a "trusted federated evidence-based analysis platform for TCM spleen-stomach diseases" is proposed, integrating blockchain-based smart contracts, federated learning, and secure multi-party computation. The deep integration of AI with privacy-preserving computing is reshaping research and clinical practice in TCM spleen-stomach diseases, providing feasible pathways and a technical framework for building a high-quality, trustworthy TCM big-data ecosystem and achieving precision syndrome differentiation.

OBJECTIVE To build a new workflow of pharmacy intravenous admixture services (PIVAS), effectively connect intelligent equipment, and promote the intelligent development of PIVAS. METHODS Based on intelligent auxiliary equipment, PIVAS workflow was optimized, and a process-oriented model was established. This model integrated intelligent prescription review (automatic prescription review+manual intervention mode), intelligent labeling, intelligent allocation, intelligent sorting, and finished infusion quality inspection system. Furthermore, an assessment was conducted to examine unreasonable medical order rate of intelligent prescription review, the working efficiency and error rate of intelligent labeling machine and intelligent sorting machine, and the dispensing efficiency and accuracy of intelligent dispensing robot. RESULTS Under the intelligent prescription review mode, the rate of unreasonable medical orders decreased from 0.157% to 0.050% (P<0.05); automatic labeling efficiency reached 21.7 sheets/min, surpassing the manual labeling efficiency of 13.8 sheets/min (P<0.05), and the daily labeling error rate decreased from 6.1‰ to 2.5‰ (P<0.05). Simultaneously operating two dispensing robots significantly improved the efficiency of batch dispensing and reduced the residual amount of liquid medicine (P<0.05); additionally, a quality testing system for finished infusion was established, involving appearance, Tyndall effect, insoluble particles, turbidity, absorbance, pH and osmotic pressure, to ensure the quality of finished infusion and reduce the risk of infusion. CONCLUSIONS The new process of PIVAS connected with intelligent devices in our hospital can improve work efficiency, reduce dispensing errors, ensure the quality of finished infusion, and improve the level of pharmaceutical care.

OBJECTIVE To analyze the differences in chemical components of Gardenia jasminoides before and after processing with ginger, and to evaluate the quality differences among different producing areas. METHODS Ultra-high performance liquid chromatography-tandem time-of-flight mass spectrometry was used to analyze the compositional differences of G. jasminoides before and after processing with ginger. The water content, total ash, and ethanol-soluble extract content of ginger- processed G. jasminoides were determined according to the 2020 edition of Chinese Pharmacopoeia. High performance liquid chromatography was adopted to determine the contents of genipin gentiobioside, geniposide, crocin Ⅰ and crocin Ⅱ in ginger- processed G. jasminoides. RESULTS A total of 49 chemical components were identified from raw G. jasminoides and ginger- processed G. jasminoides, including 14 flavonoids, 15 iridoids, 10 organic acids, 2 alkaloids and 8 other compounds. Among them, 42 components were detected in raw G. jasminoides, 28 in ginger-processed G. jasminoides, and 21 components were common to both. After processing with ginger, raw G. jasminoides lost 21 components (including iridoids, flavonoids, alkaloids, and others), while 7 chemical components were added (including coumarins, organic acids, organic acid esters, and flavonoids). For the 15 batches of ginger-processed G. jasminoides, the water content ranged from 5.64% to 7.11%, total ash from 2.92% to 4.87%, and ethanol-soluble extract from 40.61% to 58.02%. The average contents of genipin gentiobioside, geniposide, crocin Ⅰ and crocin Ⅱ were 0.108 7, 0.542 2, 0.565 0, and 0.012 5 mg/g, respectively. CONCLUSIONS After processing with ginger, G. jasminoides loses 21 components, while 7 new components are added. Differences are observed in the water content, total ash, ethanol-soluble extract, and the contents of genipin gentiobioside, geniposide, crocin Ⅰ, and crocin Ⅱ of ginger-processed G. jasminoides from different producing areas. Notably, samples from Fujian exhibit high contents of genipin gentiobioside and ethanol-soluble extract, while samples from Jiangxi have a high content of crocin Ⅰ.

ObjectiveTo observe the analgesic efficacy and safety of Qihuang acupuncture theory combined with opioid analgesics in patients with moderate to severe cancer pain due to lung cancer. MethodsPatients with moderate to severe cancer pain from lung cancer were randomly divided into Qihuang acupuncture group and control group, with 33 cases in each group. The control group was treated with long-acting opioid analgesics at maintenance doses and supplementary analgesic medications as needed. In case of breakthrough pain, short-acting opioids were used for rescue. The Qihuang acupuncture group received Qihuang acupuncture treatment in addition to the treatment used in the control group, administered once every other day, with 3 sessions constituting one treatment course. The treatment duration for both groups was 5 days. The primary outcome was the change in pain intensity, measured using the numerical rating scale (NRS) before and after treatment, and the NRS change rate was calculated. Secondary endpoints included the daily NRS change rate, the Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) score, the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire (EORTC QLQ-C30) score, and the 24-hour equivalent hydrocodone sustained-release tablet dose. Laboratory tests, including routine blood, urine, stool, liver function, and kidney function, were performed before and after treatment. Adverse events were recorded throughout the trial. ResultsAll patients completed the trial, and both groups showed a decrease in average NRS scores and PS scores after treatment, with the Qihuang acupuncture group showing lower average NRS scores and PS scores than the control group (P<0.05 or P<0.01). After treatment, the NRS change rate in the Qihuang acupuncture group was (0.42±0.17), significantly higher than that in the control group (0.14±0.27, P<0.01). The daily NRS change rate during treatment was also higher in the Qihuang acupuncture group compared to the control group (P<0.01). The Qihuang acupuncture group showed an increase in overall health status and functional scores in the EORTC QLQ-C30, and a decrease in symptom scores for fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, and financial difficulties. In contrast, overall health status and constipation scores in the control group increased, while scores of fatigue, nausea and vomiting, pain, and appetite loss decreased (P<0.05 or P<0.01). After treatment, the 24-hour equivalent hydrocodone sustained-release tablet dose did not show significant difference in the Qihuang acupuncture group (P>0.05), while the control group showed a significant increase in the 24-hour dose (P<0.01). No significant abnormalities were observed in laboratory tests before and after treatment in either group. During the study, the incidence of nausea and vomiting as well as constipation in the Qihuang acupuncture group was both 3.03% (1/33), while the incidence in the control group was 27.27% (9/33) and 36.36% (12/33), respectively, with the Qihuang acupuncture group showing significantly lower incidence (P<0.01). No serious adverse reactions were observed in either group. ConclusionQihuang acupuncture therapy combined with opioid analgesics is more effective than using opioids alone in relieving pain in patients with moderate to severe cancer pain due to lung cancer. It can improve the patients' physical condition and quality of life, reduce the dose of opioid analgesics, and has good safety.

ObjectiveTo explore the effect of serum containing Zhenwutang on myocardial mast cell apoptosis induced by angiotensin Ⅱ (AngⅡ) and the mechanism of the correlation between apoptosis and mitochondrial autophagy. MethodsIn this experiment, AngⅡ and serum containing Zhenwutang with different concentrations were used to interfere with H9C2 cardiomyocytes for 24 h, and the survival rate of H9C2 cardiomyocytes was detected by cell counting kit-8 (CCK-8) to screen the optimal concentration for the experiment. Enzyme-linked immunosorbent assay (ELISA) was used to detect the content of B-type natriuretic peptide (BNP) in cell culture supernatant, and immunofluorescence was used to detect the cell surface area to verify the construction of the myocardial mast cell model. Subsequently, the experiment was divided into a blank group (20% blank serum), a model group (20% blank serum + 5×10-5 mol·L-1 AngⅡ), low-, medium-, and high-dose (5%, 10% and 20%) serum containing Zhenwutang groups, an autophagy inhibitor group (1×10-4 mol·L-1 3-MA), and autophagy inducer group (1×10-7 mol·L-1 rapamycin). The apoptosis level of H9C2 cells and the changes of mitochondrial membrane potential were detected by flow cytometry. The lysosomal probe (Lyso Tracker) and mitochondrial probe (Mito Tracker) co-localization was employed to detect autophagy. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect Caspase-3, Caspase-9, B-cell lymphoma 2 (Bcl-2), Bcl-2-related X protein (Bax), and cytochrome C (Cyt C) in apoptosis-related pathways and the relative mRNA expression of ubiquitin ligase (Parkin), phosphatase and tensin homolog (PTEN)-induced kinase 1 (PINK1), and p62 protein in mitochondrial autophagy-related pathways. Western blot was used to detect cleaved Caspase-3, cleaved Caspase-9, Bax, Bcl-2, and Cyt C in apoptosis-related pathways, phosphorylated ubiquitin ligase (p-Parkin), phosphorylated PTEN-induced kinase 1 (p-PINK1), p62, and Bcl-2 homology domain protein Beclin1 in mitochondrial autophagy-related pathways, and the change of microtubule-associated protein 1 light chain 3 (LC3) Ⅱ/Ⅰ ratio. ResultsCCK-8 showed that when the concentration of AngⅡ was 5×10-5 mol·L-1, the cell activity was the lowest, and there was no cytotoxicity. At this concentration, the surface area of cardiomyocytes was significantly increased (P<0.01), and the content of BNP in the supernatant of culture medium was significantly increased (P<0.05). Therefore, AngⅡ with a concentration of 5×10-5 mol·L-1 was selected for the subsequent modeling of myocardial mast cells. Compared with the blank group, the model group and the autophagy inhibitor 3-MA group had a significantly increased apoptosis rate (P<0.01) and significantly decreased mitochondrial membrane potential (P<0.01). The results of immunofluorescence co-localization showed that compared with the blank group, the model group had a significantly decreased number of red and green fluorescence spots. The results of Real-time PCR showed that compared with that in the blank group, the relative mRNA expression of Bax, Caspase-3, Caspase-9, Cyt C, and p62 in the model group was significantly up-regulated (P<0.01), while the relative mRNA expression of Bcl-2, Parkin, and PINK1 was significantly down-regulated (P<0.01). In addition, the relative protein expression of Bax, cleaved Caspase-3, cleaved Caspase-9, Cyt C, and p62 was significantly up-regulated (P<0.01). The LC3Ⅱ/Ⅰ was significantly decreased, and the relative protein expression of Bcl-2, p-Parkin, p-PINK1, and Beclin1 was significantly down-regulated (P<0.01). Compared with the model group, the serum containing Zhenwutang groups and the autophagy inducer group had significantly decreased apoptosis rate (P<0.01), and the decrease ratio of mitochondrial membrane potential is significantly lowered (P<0.01) in a dose-dependent manner. Additionally, both red and green fluorescence spots became more in these groups. In the 3-MA group, the number of red and green fluorescence spots decreased significantly. The relative mRNA expression of Bax, Caspase-3, Caspase-9, Cyt C, and p62 was significantly down-regulated (P<0.05, P<0.01), while that of Bcl-2, Parkin, and PINK1 was significantly up-regulated (P<0.01). In the serum containing Zhenwutang groups, the relative protein expression levels of Bax, cleaved Caspase-3, cleaved Caspase-9, Cyt C, and p62 were significantly down-regulated (P<0.05,P<0.01). The LC3Ⅱ/Ⅰ was significantly increased, and the relative protein expression levels of Bcl-2, p-Parkin, p-PINK1, and Beclin1 were significantly up-regulated (P<0.01). ConclusionThe serum containing Zhenwutang can reduce the apoptosis of myocardial mast cells and increase mitochondrial autophagy. This is related to the inhibition of intracellular Bax/Bcl-2/Caspase-3 apoptosis pathway and regulation of Parkin/PINK1 mitochondrial autophagy pathway.
