"Sinew prescription correspondence" is the principle of selecting prescriptions for channel sinew diseases. On the basis of the theory of syndrome differentiation and treatment, the pulse manifestation corresponds to the channel sinew syndrome, which can improve the flexibility and standardization of clinical prescriptions. From the perspective of systematic dialectical sphygmology, this paper explains the dialectical relationship between channel sinew theory and pulse body elements, pulse wall elements, pulse elements and blood flow elements, and clarifies the internal relationship between pulse manifestation and prescriptions at the level of channel sinew disease. The prescription is derived from the method, while the method is established with the syndrome, and the prescription is unified by the method. According to the theory of "sinew prescription correspondence", the treatment ideas of channel sinew diseases were analyzed from the perspective of channel sinew distribution, functional characteristics and structural changes. On this basis, the diagnosis of channel sinew disease and the application of prescriptions are expanded, and the research on the internal treatment and diagnosis mode of "pulse manifestation-channel sinew-zang fu (脏腑)" is prospected, so as to expand the differentiation and treatment methods of channel sinew theory.

ObjectiveTo clarify whether METTL14 mediates the core role of acupuncture at Neiguan (PC6) in promoting myelination and improving behavior in young autistic rats through gene intervention technology. MethodsThe ASD model was established by intraperitoneal injection of valproic acid (VPA) in pregnant rats. Male offspring were intracerebroventricularly injected with adenovirus-packaged METTL14 shRNA (sh-METTL14) or its control (sh-NC) on postnatal day 1, with a model group set as well. Subsequently, the juvenile rats were divided into model group, acupuncture group, acupuncture+sh-NC group, and acupuncture+sh-METTL14 group. The acupuncture group received acupuncture at Neiguan (PC6) from postnatal day 7, once daily for 21 consecutive days. Neurobehavioral changes were evaluated by behavioral tests; METTL14 knockdown efficiency and the expression of METTL14, METTL3, and PTEN were detected by quantitative real-time PCR (qRT-PCR) and Western blot (WB); PTEN m6A levels were measured by RNA immunoprecipitation-qPCR (RIP-qPCR); myelin ultrastructure, expression of myelin basic protein (MBP) and neurofascin 155 (NF155), and dendritic spine density were observed using transmission electron microscopy (TEM), enzyme-linked immunosorbent assay (ELISA), immunofluorescence, qRT-PCR, and primary neuron culture. ResultsBehaviorally, knockdown of METTL14 significantly counteracted the beneficial effects of acupuncture in improving self-grooming, open field exploration, three-chamber social interaction, and Morris water maze learning and memory (P<0.05, P<0.01). Compared with the acupuncture+sh-NC group, the acupuncture+sh-METTL14 group showed significantly decreased mRNA and protein expression of hippocampal METTL14 (P<0.01), and the upregulating effects of acupuncture on METTL3 and PTEN expression were reversed (P<0.01). Meanwhile, knockdown of METTL14 significantly inhibited the acupuncture-induced increase in PTEN m6A levels (P<0.01). Morphologically, knockdown of METTL14 attenuated the improvement of myelin structure by acupuncture, reversed the downregulation of MBP and upregulation of NF155 induced by acupuncture, and blocked the increase in dendritic spine density (P<0.05, P<0.01). ConclusionMETTL14 is a key molecule mediating the therapeutic effect of acupuncture at Neiguan. Acupuncture at Neiguan upregulates METTL14, thereby enhancing m6A methylation modification of PTEN mRNA to stabilize its expression, ultimately promoting myelin development and improving behavioral symptoms in ASD juvenile rats. This preliminarily reveals the modern biological connotation of “opening Xuanfu and dredging myelin”.

ObjectiveTo investigate the mechanism by which Shaoyaotang regulates the miRNA-155-mediated suppressor of cytokine signaling 1 (SOCS1)/Janus kinase 1 (JAK1)/signal transducer and activator of transcription 1 (STAT1) signaling pathway and thereby affects macrophage polarization. MethodsThe cell-counting kit-8 (CCK-8) assay was used to detect the effect of drug-containing serum of Shaoyaotang at different concentrations on the viability of RAW 264.7 cells. A cell model of inflammation was established by stimulating RAW264.7 cells with lipopolysaccharide (LPS) at a concentration of 10 mg·L-1 The modeled cells were assigned by the random number table method into seven groups: LPS-induced M1 polarization (model), M1+miRNA-155 mimics, M1+miRNA-155 inhibitor, M1+Shaoyaotang-containing serum, M1+miRNA-155 mimics+Shaoyaotang-containing serum, M1+miRNA-155 inhibitor+Shaoyaotang-containing serum, and M1+blank serum. Enzyme-linked immunosorbent assay was employed to measure the levels of inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β)]. Immunofluorescence assay was used to detect the expression of macrophage polarization markers [inducible nitric oxide synthase (iNOS) and macrophage mannose receptor 1 (CD206)]. Real-time PCR was employed to measure the expression of miRNA-155 in cells. Western blot was performed to determine the protein levels of SOCS1, STAT1, and JAK1. ResultsCompared with the LPS-induced M1 polarization (model) group, the M1+miRNA-155 mimics group showed up-regulated expression of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS (P<0.05) and down-regulated expression of CD206 (P<0.05). In both the M1+miRNA-155 inhibitor group and the M1+Shaoyaotang-containing serum group, the expression levels of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS were down-regulated (P<0.05), while those of SOCS1 and CD206 were up-regulated (P<0.05). Compared with the M1+miRNA-155 mimics group, the M1+miRNA-155 mimics+Shaoyaotang-containing serum group showed down-regulated expression of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS (P<0.05) and up-regulated expression of SOCS1 and CD206 (P<0.05). Compared with the M1+miRNA-155 inhibitor group, the M1+miRNA-155 inhibitor+Shaoyaotang-containing serum group showed down-regulated expression of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS (P<0.05) and up-regulated expression of SOCS1 and CD206 (P<0.05). ConclusionShaoyaotang regulates macrophage polarization by modulating miRNA-155 expression and interfering with the SOCS1/JAK1/STAT1 signaling pathway. The findings provide new experimental evidence for the treatment of ulcerative colitis with Shaoyaotang.

ObjectiveTo investigate the potential role and underlying mechanisms of Shaoyaotang in intervening macrophage glycolytic reprogramming in ulcerative colitis (UC). MethodsForty-eight C57BL/6 mice were randomly divided into six groups: Normal control group, model group, mesalazine group (0.39 g·kg-1), Shaoyaotang group (15.54 g·kg-1), 2-deoxy-D-glucose (2-DG) group (glycolysis inhibitor, 100 mg·kg-1), and 2-DG + Shaoyaotang combined group (100 mg·kg-1+15.54 g·kg-1). Except for the normal control group, mice in the other five groups were induced to establish UC models using dextran sulfate sodium (DSS). The normal control group was administered pure water via intragastric gavage, while the other groups received intragastric gavage of mesalazine solution, intragastric gavage of Shaoyaotang, and the 2-DG group was treated with 2-DG via intraperitoneal injection. After 7 consecutive days of treatment, colonic tissues were extracted. Hematoxylin and eosin (HE) staining was performed to evaluate histopathological changes and tissue injury in the colon. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α) in colonic tissues. Western blot analysis was employed to determine the expression levels of hypoxia-inducible factor-1α (HIF-1α), glucose transporter (GLUT1), lactate dehydrogenase A (LDHA), pyruvate kinase M2 (PKM2), and 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3) in colonic tissues. Immunofluorescence was conducted to detect the expression of CD206 and inducible nitric oxide synthase (iNOS) in colonic tissues. Liquid chromatography-mass spectrometry (LC-MS) was utilized to measure lactate and citrate levels in colonic tissues. ResultsCompared with the normal control group, mice in the model group exhibited a significant increase in disease activity index (DAI) scores, accompanied by colonic mucosal congestion, edema, and inflammatory cell infiltration, significantly elevated expression of the inflammatory cytokine TNF-α (P<0.05), significantly decreased IL-10 expression (P<0.05), significantly increased levels of HIF-1α, GLUT1, LDHA, PKM2, and PFKFB3 in colonic tissues (P<0.05), markedly elevated iNOS expression (P<0.05), significantly decreased CD206 expression (P<0.05), and significantly elevated lactate and citrate levels in colonic tissues (P<0.05). In contrast to the model group, the Shaoyaotang group, inhibitor group, and Shaoyaotang combined with inhibitor group demonstrated amelioration of mucosal injury in colonic tissues, markely decreased expression levels of the inflammatory cytokine TNF-α (P<0.05), elevated IL-10 expression levels, significantly decreased expression of HIF-1α, GLUT1, LDHA, PKM2, and PFKFB3 (P<0.05), markedly reduced iNOS expression levels (P<0.05), significantly increased CD206 expression (P<0.05) and significantly decreased lactate and citrate levels (P<0.05). ConclusionShaoyaotang ameliorates symptoms of DSS-induced UC in mice, and its therapeutic mechanism may be associated with regulating macrophage glycolytic reprogramming via modulation of the HIF-1α signaling pathway.

ObjectiveTo investigate the role of microRNA-155-5p (miR-155-5p) in ulcerative colitis (UC) and study the molecular mechanism of Shaoyaotang in the treatment of UC by regulating miR-155-5p. MethodsForty-eight SPF-grade male C57BL/6 mice were selected and assigned via the random number table method into 6 groups (n=8): A blank control group, a model group, a mesalazine (0.39 g·kg-1) group, a Shaoyaotang (31.08 g·kg-1) group, a Janus kinase 1 (JAK1) inhibitor (baricitinib, 10 mg·kg-1) group, and a Shaoyaotang combined with inhibitor (baricitinib 10 mg·kg-1 + Shaoyaotang 31.08 g·kg-1) group. After successful modeling of UC by gavage of 3% dextran sulphate sodium solution, each group received corresponding drug intervention for 7 days. Shaoyaotang and mesalazine were administered by gavage, and baricitinib by intraperitoneal injection. Twenty-four hours after the last administration, mice were anesthetized by intraperitoneal injection of pentobarbital sodium, and blood was collected for determination of white blood cell count and erythrocyte sedimentation rate (ESR). Mice were then sacrificed for measurement of colon length. Hematoxylin-eosin staining was used to observe colonic pathological changes and perform pathological scoring. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was employed to determine the relative expression of miR-155-5p in the colonic tissue, and Western blot was used to determine the protein levels of JAK1, phosphorylated JAK1 (p-JAK1), suppressor of cytokine signaling 1 (SOCS1), signal transducer and activator of transcription 1 (STAT1), and phosphorylated STAT1 (p-STAT1). ResultsCompared with the blank control group, the model group showed increased disease activity index (DAI) score and pathological score, shortened colon, upregulated relative expression of miR-155-5p and protein levels of p-JAK1 and p-STAT1, downregulated protein level of SOCS1 in the colonic tissue, prolonged time of erythrocyte sedimentation, and increased white blood cell count (P<0.01). Compared with the model group, all drug-treated groups exhibited improvements in the above indicators (P<0.01). Moreover, the Shaoyaotang group showed better therapeutic effects than the mesalazine group in regulating miR-155-5p expression, related protein levels, DAI score, and colonic pathological score (P<0.01). ConclusionShaoyaotang may downregulate miR-155-5p to relieve its inhibition on SOCS1, thereby suppressing the excessive activation of the JAK1/STAT1 signaling pathway and ultimately alleviating intestinal inflammatory damage.

In recent years, as the incidence of ulcerative colitis (UC) is growing, intestinal mucosal injury has garnered increasing attention, and it is characterized by high recurrence, risk of inflammation-cancer transformation, and difficulty in repair. Intestinal mucosal injury in UC is centered on persistent inflammation and barrier dysfunction, with its pathological mechanisms involving endoplasmic reticulum stress (ERS)-mediated changes such as abnormal apoptosis, abnormal autophagy, and inflammatory responses. ERS induces apoptosis of intestinal epithelial cells, disrupts tight junction proteins, and exacerbates inflammatory responses through pathways such as protein kinase R-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme 1 alpha (IRE1α), and activating transcription factor 6 (ATF6), ultimately causing intestinal mucosal injury. Traditional Chinese medicine (TCM) has a long history of research on UC. The theory of sores depending on spleen-earth holds that spleen deficiency is the fundamental cause of UC, while pathological products such as dampness-turbidity and blood stasis are the secondary manifestations. Dysfunction of the spleen-earth leads to insufficient production and transformation of Qi and blood, malnutrition of the intestinal mucosa, and invasion of external pathogens. In the active phase of UC, spleen deficiency is often accompanied by excessive pathogenic factors such as dampness-heat and heat-toxin, leading to acute intestinal mucosal damage. In the remission phase, however, it is mainly characterized by spleen deficiency and healthy Qi deficiency, accompanied by residual pathogens, resulting in weak intestinal mucosal repair. Studies have shown that the endoplasmic reticulum, as a key site for protein synthesis and folding, has functions highly similar to the TCM concept of the spleen governing transportation and transformation. From a TCM perspective, the endoplasmic reticulum can be regarded as the carrier of spleen transportation, and ERS is a microcosmic manifestation of spleen dysfunction, leading to intestinal mucosal injury. ERS impairs the structure and function of the endoplasmic reticulum, induces the generation of abnormal Qi, and triggers pathological changes, making inflammation difficult to be reduced and causing the aggravation of ERS, forming a vicious cycle of spleen deficiency-pathological products-intestinal injury. TCM has unique advantages in regulating ERS to prevent and treat intestinal mucosal injury. According to the theory of sores depending on spleen-earth and the modern medical understanding of ERS, this paper delves into the TCM and Western medicine pathogenesis of intestinal mucosal injury in UC. Furthermore, this paper discusses the roles of TCM active components and compound formulas in reducing intestinal mucosal injury in UC by regulating ERS under the guidance of the treatment principles of invigorating the spleen and replenishing Qi as the key and dispelling dampness and removing blood stasis as the supplementation, aiming to provide new ideas and methods for the prevention and treatment of UC.

This study employed the "disease-medicine-dose" pattern to mine the medication rules of traditional Chinese medicine(TCM) prescriptions containing Astragali Radix in ancient Chinese medical books, aiming to provide a scientific basis for the clinical application of Astragali Radix and the development of new medicines. The TCM prescriptions containing Astragali Radix were retrieved from databases such as Chinese Medical Dictionary and imported into Excel 2020 to construct the prescription library. Statical analysis were performed for the prescriptions regarding the indications, syndromes, medicine use frequency, herb effects, nature and taste, meridian tropism, dosage forms, and dose. SPSS statistics 26.0 and IBM SPSS Modeler 18.0 were used for association rules analysis and cluster analysis. A total of 2 297 prescriptions containing Astragali Radix were collected, involving 233 indications, among which sore and ulcer, consumptive disease, sweating disorder, and apoplexy had high frequency(>25), and their syndromes were mainly Qi and blood deficiency, Qi and blood deficiency, Yin and Yang deficiency, and Qi deficiency and collateral obstruction, respectively. In the prescriptions, 98 medicines were used with the frequency >25 and they mainly included Qi-tonifying medicines and blood-tonifying medicines. Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Ginseng Radix et Rhizoma, Atractylodis Macrocephalae Rhizoma, and Citri Reticulatae Pericarpium were frequently used. The medicines with high frequency mainly have warm or cold nature, and sweet, pungent, or bitter taste, with tropism to spleen, lung, heart, liver, and kidney meridians. In the treatment of sore and ulcer, Astragali Radix was mainly used with the dose of 3.73 g and combined with Glycyrrhizae Radix et Rhizoma to promote granulation and heal up sores. In the treatment of consumptive disease, Astragali Radix was mainly used with the dose of 37.30 g and combined with Ginseng Radix et Rhizoma to tonify deficiency and replenish Qi. In the treatment of sweating disorder, Astragali Radix was mainly used with the dose of 3.73 g and combined with Glycyrrhizae Radix et Rhizoma to consolidate exterior and stop sweating. In the treatment of apoplexy, Astragali Radix was mainly used with the dose of 7.46 g and combined with Glycyrrhizae Radix et Rhizoma to dispell wind and stop convulsions. Astragali Radix can be used in the treatment of multiple system diseases, with the effects of tonifying Qi and ascending Yang, consolidating exterior and stopping sweating, and expressing toxin and promoting granulation. According to the manifestations of different diseases, when combined with other medicines, Astragali Radix was endowed with the effects of promoting granulation and healing up sores, tonifying deficiency and Qi, consolidating exterior and stopping sweating, and dispelling wind and replenishing Qi. The findings provide a theoretical reference and a scientific basis for the clinical application of Astragali Radix and the development of new medicines.

Colorectal cancer(CRC) is a common malignant tumor worldwide. Due to the treatment intolerance and side effects, CRC rank the top among various cancers regarding the incidence and mortality rates. Therefore, exploring new therapies is of great significance for the treatment of CRC. Aerobic glycolysis(AEG) plays an important role in the microenvironment formation, proliferation, metastasis, and recurrence of CRC and other tumor cells. It has been confirmed that intervening in the AEG pathway can effectively curb CRC. The active ingredients and compound prescriptions of traditional Chinese medicine(TCM) can effectively inhibit the proliferation, metastasis, and drug resistance and regulate the apoptosis of tumor cells by modulating AEG-associated transport proteins [eg, glucose transporters(GLUT)], key enzymes [hexokinase(HK) and phosphofructokinase(PFK)], key genes [hypoxia-inducible factor 1(HIF-1) and oncogene(c-Myc)], and signaling pathways(MET/PI3K/Akt/mTOR). Accordingly, they can treat CRC, reduce the recurrence, and improve the prognosis of CRC. Although AEG plays a key role in the development and progression of CRC, the specific mechanisms are not yet fully understood. Therefore, this article delves into the intrinsic connection of the targets and mechanisms of the AEG pathway with CRC from the perspective of tumor cell glycolysis and explores how active ingredients(oxymatrine, kaempferol, and dioscin) and compound prescriptions(Quxie Capsules, Jiedu Sangen Decoction, and Xianlian Jiedu Prescription) of TCM treat CRC by intervening in the AEG pathway. Additionally, this article explores the shortcomings in the current research, aiming to provide reliable targets and a theoretical basis for treating CRC with TCM.

OBJECTIVE:
Gastric cancer (GC) is one of the most common malignancies seen in clinic and requires novel treatment options. Morin is a natural flavonoid extracted from the flower stalk of a highly valuable medicinal plant Prunella vulgaris L., which exhibits an anti-cancer effect in multiple types of tumors. However, the therapeutic effect and underlying mechanism of morin in treating GC remains elusive. The study aims to explore the therapeutic effect and underlying molecular mechanisms of morin in GC.
METHODS:
For in vitro experiments, the proliferation inhibition of morin was measured by cell counting kit-8 assay and colony formation assay in human GC cell line MKN45, human gastric adenocarcinoma cell line AGS, and human gastric epithelial cell line GES-1; for apoptosis analysis, microscopic photography, Western blotting, ubiquitination analysis, quantitative polymerase chain reaction analysis, flow cytometry, and RNA interference technology were employed. For in vivo studies, immunohistochemistry, biomedical analysis, and Western blotting were used to assess the efficacy and safety of morin in a xenograft mouse model of GC.
RESULTS:
Morin significantly inhibited the proliferation of GC cells MKN45 and AGS in a dose- and time-dependent manner, but did not inhibit human gastric epithelial cells GES-1. Only the caspase inhibitor Z-VAD-FMK was able to significantly reverse the inhibition of proliferation by morin in both GC cells, suggesting that apoptosis was the main type of cell death during the treatment. Morin induced intrinsic apoptosis in a dose-dependent manner in GC cells, which mainly relied on B cell leukemia/lymphoma 2 (BCL-2) associated agonist of cell death (BAD) but not phorbol-12-myristate-13-acetate-induced protein 1. The upregulation of BAD by morin was due to blocking the ubiquitination degradation of BAD, rather than the transcription regulation and the phosphorylation of BAD. Furthermore, the combination of morin and BCL-2 inhibitor navitoclax (also known as ABT-737) produced a synergistic inhibitory effect in GC cells through amplifying apoptotic signals. In addition, morin treatment significantly suppressed the growth of GC in vivo by upregulating BAD and the subsequent activation of its downstream apoptosis pathway.
CONCLUSION
Morin suppressed GC by inducing apoptosis, which was mainly due to blocking the ubiquitination-based degradation of the pro-apoptotic protein BAD. The combination of morin and the BCL-2 inhibitor ABT-737 synergistically amplified apoptotic signals in GC cells, which may overcome the drug resistance of the BCL-2 inhibitor. These findings indicated that morin was a potent and promising agent for GC treatment.
