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.

Diabetic Peripheral Neuropathy (DPN) is one of the most common and harmful complications of type 2 diabetes. DPN's pathogenesis include high blood sugar-induced oxidative stress, inflammation, and mitochondrial dysfunction. These factors are combined to damage nerve fibers, leading to sensory issues, pain, and numbness. Through a coordinated effect, these factors trigger nerve fiber damage and lead to sensory abnormalities, pain and numbness in limbs, and other symptoms, seriously restricting patients' activities of daily living and mobility. Recent research highlights that cellular senescence plays a critical role in DPN. Cellular senescence is manifested by the loss of cell proliferation ability, and further aggravates nerve damage via oxidative stress, mitochondrial dysfunction, autophagy impairment, inflammatory reaction, and other mechanisms, accelerating DPN occurrence and progression. In terms of medical treatment, current methods focus on blood sugar control, pain relief medicine, and microcirculation improvement, while no therapy has been developed based on cellular senescence. In contrast, traditional Chinese medicine (TCM) shows a unique advantage in DPN prevention and treatment via cellular senescence modulation. TCM emphasizes a holistic approach, as well as syndrome differentiation and treatment, effective in anti-aging and nerve damage repair. Recent studies show that TCM active ingredients, including puerarin, ginsenosides, and berberine, can reduce inflammation, oxidative stress, and apoptosis via signaling pathway regulation, thereby slowing cellular senescence to alleviate nerve damage. Furthermore, TCM compounds such as Buyang Huanwutang, Taohong Siwutang, and Huangqi Guizhi Wuwutang exert synergistic effects on cellular senescence-related pathways to improve nerve health and reduce DPN clinical symptoms. Therefore, this paper reviews the literature related to the interaction between cellular senescence and DPN from the perspective of cellular senescence, summarizing the mechanism of DPN and TCM intervention strategies.

OBJECTIVE To investigate the mechanism of Xihuang pill (XHP) against diffuse large B-cell lymphoma (DLBCL). METHODS The active ingredients of XHP and potential therapeutic targets for DLBCL were identified using TCMSP, GeneCards and DisGeNET databases. Protein-protein interaction networks were constructed using the String database and Cytoscape software to screen core components and core targets. Gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were then performed. The clinical relevance of core targets was analyzed using the GEPIA and PanCanSurvPlot databases. Molecular docking and molecular dynamics (MD) simulation were conducted to verify the interactions between core components and core targets, and the binding free energy was calculated using the molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) method. The effects of XHP on DLBCL and the related molecular mechanisms were validated using CCK-8 assay, flow cytometry and Western blot. RESULTS Network pharmacology analysis identified 108 active ingredients of XHP and 410 potential therapeutic targets for DLBCL. Six core components (e.g., 17 beta-estradiol, quercetin) and ten core targets [e.g., tumor protein 53 (TP53), proto-oncogene tyrosine-protein kinase Src (SRC)] were obtained. Enrichment analysis indicated that the anti-DLBCL effects of XHP were primarily associated with the apoptotic signaling pathway, the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway and so on. Clinical correlation analysis revealed that TP53 and SRC expression were significantly up-regulated in DLBCL tissues and associated with poor patient prognosis (P<0.05). Molecular docking, MD simulations and MM-PBSA calculations confirmed that the SRC-quercetin complex had a mail:stronger and more stable binding affinity. In vitro experiments demonstrated that XHP concentration-dependently inhibited the proliferation of DLBCL cells; compared with control group, XHP medium- and high-dose groups could significantly induce the apoptosis of SU-DHL2 and SU-DHL4 cells, and significantly down- regulated the expressions of SRC protein, phosphorylated (p)-PI3K/PI3K and p-Akt/Akt in SU-DHL4 cells (P<0.05). CONCLUSIONS XHP may inhibit the proliferation and induce the apoptosis of DLBCL cells by regulating the SRC/PI3K/Akt signaling pathway.

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.

Objective:
To investigate whether membrane vesicles (MVs) of Streptococcus mutans (S.mutans) contain autoinducer-2 (AI-2) and to preliminarily explore the effects of these MVs on the growth and biofilm formation of S. mutans.
Methods:
MVs were isolated from the S. mutans UA159 strain using differential centrifugation. The isolated MVs were characterized by nanoparticle tracking analysis for particle size and concentration and observed by transmission electron microscopy. The presence of AI-2 was identified using the Vibrio harveyi BB170 bioluminescence assay: the BB170 diluent was supplemented with AB medium (control group), MV extract (MVs group), pre-ultrafiltration supernatant (Sup group), or post-ultrafiltration supernatant (Sup-af group). The effects of MVs on growth and biofilm formation were assessed using the S.mutans UA159 strain or a luxS deletion mutant as the control group, compared with experimental groups stimulated with gradient concentrations of MVs (MVs-2.0E+7, MVs-2.0E+8, and MVs-2.0E+9 groups). Growth curves, MTT assay, and colony-forming unit (CFU) counts were used to determine changes in growth capacity. Biofilm formation was evaluated using crystal violet staining, confocal laser scanning microscopy, and the anthrone method for polysaccharide quantification.
Results:
Enriched S. mutans MVs were successfully obtained, with an average particle size of approximately 94.19 nm and a concentration of 1.87E+11 particles/mL. The bioluminescence assay showed that the luminescence intensity of the Sup group was higher than that of the Sup-af group, and the MVs group exhibited higher intensity than the control group. Assessments via growth curves, MTT assay, and CFU counts indicated no significant differences in the growth capacity of the various S. mutans strains after treatment with different concentrations of MVs. Crystal violet staining quantification and confocal laser scanning microscopy observations revealed that high-concentration MV treatment (2.0E+9 particles/mL group) resulted in lower biofilm mass compared to the control. The anthrone method showed that the production of both water-soluble and water-insoluble polysaccharides was significantly lower in the high-concentration MV group than in the control.
Conclusion
S. mutans MVs contain the quorum sensing signal molecule AI-2. These MVs do not significantly affect the growth of S. mutans, but they can regulate biofilm formation and exhibit an inhibitory effect at high concentrations.

This article systematically analyzed the historical evolution of the origin, scientific name, producing area, quality evaluation, harvesting and processing, and other aspects of Quisqualis Fructus by consulting the ancient materia medica, medical books, prescription books, local literature and combining with the modern literature and standards, summarized and explored the development rules of its medicinal properties and efficacy along with their underlying causes, in order to provide support for the development and utilization of famous classical formulas containing this herb. According to the textual research, Shijunzi was first recorded as Liuqiuzi in Nanfang Caomuzhuang of the Jin dynasty, and the name of Shijunzi was first used in Kaibao Bencao of the Song dynasty, which has been consistently used throughout subsequent dynasties, and there were also aliases such as Junziren, Sijunzi, and Dujilizi. The mainstream source of Quisqualis Fructus used in the past dynasties has been the dried mature fruits of Quisqualis indica, a plant belonging to the family Combretaceae. In modern times, its variety Q. indica var. villosa has also been recorded as the medicinal material of Quisqualis Fructus. In 2007, the Flora of China(English edition) designated Q. indica var. villosa as a synonym of Q. indica. Today, the accepted name of Shijunzi is updated to Combretum indicum. According to ancient herbal records, the producing areas of Quisqualis Fructus were Guangdong, Hong Kong, Macao, Guangxi, Hainan, Sichuan and Fujian, and then gradually expanded to Yunnan, Taiwan, Jiangxi and Guizhou. Since the Song dynasty, two major production regions have gradually emerged in Sichuan, Chongqing and Fujian. Currently, it is primarily cultivated in Chongqing, Guangxi and other areas, with Chongqing yielding the highest output. Since modern times, superior quality has been defined by large size, a purple-black surface, plump grains, and a yellowish-white kernel. According to ancient herbal records, the harvesting period of Quisqualis Fructus was the July and August of the lunar calendar, mostly used raw after shelling or with the shell intact, it underwent processing methods such as cleaning, slicing, mixing, steaming, roasting, stewing, and frying. Currently, the harvesting period is autumn, followed by sun-drying or low-heat drying, with processing methods including cleaning, stir-frying, and stewing. In ancient and modern literature, the records of the properties, functions and indications of Quisqualis Fructus are basically the same, that is, sweet in taste, warm in nature, predominantly non-toxic, belonging to the spleen and stomach meridians. It possesses effects of insecticide, decontamination and invigorating spleen for ascariasis, enterobiasis, abdominal pain due to worm accumulation and infantile malnutrition.The contraindications for use primarily include avoiding consumption by individuals without parasitic infestations, limiting use for those with spleen-stomach deficiency-cold, refraining from drinking hot tea during medication, and avoiding excessive intake. Based on the textual research, it is suggested that the dried mature fruits of Q. indica should be used as the medicinal material for the development of famous classical formulas containing Quisqualis Fructus. Processing methods may be chosen according to prescription requirements, and the raw products is recommended for medicinal use if not specified.

ObjectiveTo investigate the efficacy of sequential tenofovir alafenamide fumarate (TAF) therapy versus the regimen of entecavir (ETV) combined with TAF in chronic hepatitis B (CHB) patients experiencing low-level viremia (LLV) after ETV therapy, as well as their impact on virologic response, liver and renal function, and blood lipid levels. MethodsA total of 217 CHB patients with LLV after ETV treatment who were admitted to Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from May 2020 to December 2023 were enrolled, and according to the treatment regimen, they were divided into TAF group (180 patients receiving sequential TAF therapy) and combined group (37 patients receiving ETV+TAF therapy). The propensity score matching (PSM) method was used to match the patients at a ratio of 1∶1, and finally 37 patients were included in each group to balance the baseline confounding factors. The two groups were compared in terms of hepatitis B virus DNA (HBV DNA) clearance rate, hepatitis B envelope antigen (HBeAg) clearance rate, liver and renal function parameters (liver stiffness measurement [LSM], platelet count [PLT], aspartate aminotransferase [AST], alanine aminotransferase [ALT], and creatinine [Cr]), blood lipid levels (total cholesterol [TC], triglyceride [TG], high-density lipoprotein cholesterol [HDL-C], and low-density lipoprotein cholesterol [LDL-C]), and the incidence rate of adverse reactions. The independent samples t-test was used for comparison of normally distributed continuous data between two groups, and the paired t-test was used for comparison within each group; the chi-square test was used for comparison of categorical data between groups. ResultsAfter 48 weeks of treatment, compared with the TAF group, the combined group had significantly higher HBV DNA clearance rate (86.49% vs 59.46%, χ²=6.852, P=0.009) and HBeAg clearance rate (59.46% vs 35.14%, χ²=4.391, P=0.036). After treatment, compared with the TAF group, the combined group had significantly lower levels of LSM (7.01±1.50 kPa vs 7.90±1.68 kPa, t=2.404, P=0.019), AST (18.02±2.28 U/L vs 21.12±2.85 U/L, t=5.166, P<0.001), and ALT (19.85±3.86 U/L vs 22.00±3.90 U/L, t=2.383, P=0.020) and significantly higher levels of PLT [(218.35±42.60)×109/L vs (192.82±44.13)×109/L, t=2.532, P=0.014] and Cr (70.92±6.54 μmoL/L vs 67.60±6.13 μmoL/L, t=2.253, P=0.027). After treatment, there was a slight increase in the level of TC in both the TAF group (5.60±0.89 mmol/L vs 5.18±0.85 mmol/L, t=2.076, P=0.041) and the combined group (5.45±0.80 mmol/L vs 5.02±0.83 mmol/L, t=2.269, P=0.026). There was no significant difference in the incidence rate of adverse reactions between the TAF group and the combined group (21.62% vs 18.92%, χ²=0.084, P=0.772). ConclusionFor ETV-treated CHB patients experiencing LLV, compared with sequential TAF therapy, the ETV+TAF combined therapy can effectively increase virologic response rate, alleviate liver fibrosis, and improve liver function, whereas sequential TAF therapy has less impact on renal function. Sequential or combined therapy with TAF may induce a slight increase in the level of TC, which should be taken seriously in clinical practice.

ObjectiveTo investigate the inhibitory effect of Biejiajian Pills (BJJW) on the growth of liver cancer, as well as its potential mechanism in mediating the AMP-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) pathway through mitochondrial energy metabolism. MethodsHuman hepatoma Huh7 cells were used to establish a nude mouse model of subcutaneous xenograft tumor. A total of 18 tumor-bearing nude mice were randomly divided into model group, BJJW group (2.2 g/kg), and metformin group (250 mg/kg), and the corresponding drug was given by gavage for 14 consecutive days. Tumor volume and weight were monitored during the experiment; HE staining was used to observe histopathological changes; the levels of reactive oxygen species (ROS) and adenosine triphosphate (ATP) in tumor tissue were measured; immunohistochemistry and Western blotting were used to measure the expression levels of proteins associated with the AMPK/mTOR pathway. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the Tukey’s test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Dunn’s test was used for further comparison between two groups. ResultsCompared with the model group, the BJJW group had a tumor inhibition rate of 45.73%, with significant reductions in both tumor volume and weight (P<0.01). Pathological examination showed that compared with the model group, the BJJW group had a significant reduction in the number of tumor cells and the presence of extensive necrosis. Mechanistic studies showed that compared with the model group, the BJJW group had a significant increase in ROS level (P<0.001) and a significant reduction in ATP level (P<0.001), as well as significant increases in p-AMPK/AMPK ratio (0.81±0.20 vs 0.13±0.04, P<0.01) and p-ULK1/ULK1 ratio (0.69±0.17 vs 0.18±0.13, P<0.01) and a significant reduction in p-mTOR/mTOR ratio (1.34±0.16 vs 3.20±0.62, P<0.01). ConclusionBJJW may inhibit the growth of liver cancer by inducing mitochondrial energy metabolism dysfunction, increasing the level of ROS, reducing the level of ATP, and activating the AMPK/mTOR signaling pathway.
