Hypertrophic cardiomyopathy, a genetic hereditary disease, is highly regarded in clinical practice due to its unique pathophysiological changes, course characteristics, and hemodynamic features. With the continuous advance of treatment methods such as medications and surgeries, the prevention, treatment and prognosis of hypertrophic cardiomyopathy has gradually improved. However, inappropriate use of positive inotropic drugs may lead to serious consequences that are difficult to reverse. Therefore, how to smoothly navigate through the perioperative period and ensure clinical safety poses a great challenge for anesthesiologists. This paper discusses the perioperative management of patients with hypertrophic cardiomyopathy, with the hope of enhancing anesthesiologists' management capabilities for this type of disease.

OBJECTIVE To design and synthesize mono-carbonyl curcumin analogues(MCACs) and investigate the activities of them against breast cancer. METHODS The analogues F1, F2, and F3 were obtained by aldol condensation reaction, and their antitumor activities(including the activities of human breast cancer cell MCF-7 and human lung cancer cell A549) were detected by MTT assay [evaluated with half inhibitory concentration(IC50)]. The results of MTT assay were compared with those of curcumin. Bioinformatics methods were used to collect the core targets of analogues F1, F2 and F3 acting on breast cancer, and then molecular docking verification was carried out. The cell experiments were conducted to investigate the effects of high, medium and low concentrations (16, 8, 4 μmol/L) of F1, F2 and F3 on the expression of the first core target protein as well as the effects of medium concentration of F1, F2 and F3 on the expression of cleaved-caspase-3. RESULTS Compared with curcumin, IC50 of analogues F1, F2 and F3 to A549 and MCF-7 cells(except for IC50 of analogue F2 to A549 cells) were decreased significantly(P< 0.05 or P<0.01); among them, IC50 of analogue F2 to MCF-7 cell was the lowest, being(9.67±1.27) μmol/L. Bioinformatics analysis showed that index of affinity of analogues F1, F2 and F3 with the first core target epidermal growth factor receptor (EGFR), protein kinase B (AKT) and AKT were 5.909 2, 8.402 5 and 6.486 6, respectively; high concentration of F1 could significantly reduce the phosphorylation level of EGFR protein in MCF-7 cells(P<0.01), while low, medium, and high concentrations of F2 and high concentration of F3 could significantly reduce the phosphorylation level of AKT protein in MCF-7 cells(P<0.05 or P<0.01). Medium concentration of F1, F2, and F3 could significantly increase the expression level of cleaved- caspase-3 protein in MCF-7 cells(P<0.01). CONCLUSIONS Designed and synthesized MCACs F1, F2 and F3 all have good anti- breast cancer activity, and F2 has better anti-breast cancer activity.

ObjectiveThis study aimed to investigate the intervention effect of Renqing Mangjue on the malignant transformation of gastric mucosal epithelial cells induced by N-methyl-N′-nitro-N-nitrosoguanidine (MNNG) and to explore its molecular mechanism in preventing precancerous lesions of gastric cancer based on the cyclic guanosine monophosphate (cGMP)/protein kinase G (PKG)/mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinase (ERK) signaling pathway. MethodsHuman gastric mucosal epithelial cells (GES-1) were initially induced by MNNG to establish a precancerous cell model (MC cells). The effective concentration of MNNG for inducing malignant transformation in GES-1 cells was screened using the cell proliferation activity decection (CCK-8) assay, and the effective concentration of Renqing Mangjue for inhibiting the proliferation of transformed GES-1 cells was also determined. GES-1 cells were divided into a blank control group, a model group, and treatment groups with Renqing Mangjue at concentrations of 1, 3, 10, and 30 mg·L-1. Furthermore, the effects of Renqing Mangjue on the migratory ability and epithelial-mesenchymal transition (EMT) characteristics of GES-1 malignant transformed cells were evaluated using Transwell migration assays, wound healing assays, and real-time quantitative reverse transcription polymerase chain reaction (Real-time PCR). Additionally, candidate chemical components and target sites of Renqing Mangjue were obtained from the TCMIP v2.0 database, and disease targets at various stages of gastric cancer precursors were sourced from the Gene Expression Omnibus (GEO) database. Pathway enrichment analysis was performed using the Metascape database to predict the potential mechanisms of action of Renqing Mangjue. Finally, the protective mechanism of Renqing Mangjue against gastric cancer precursors was validated through Western blot analysis. ResultsAt a concentration of 20 μmol·L-1, MNNG exhibited an inhibition rate of approximately 50% on GES-1 cells (P<0.01), and at this concentration, the GES-1 cells displayed biological characteristics indicative of malignant transformation. In contrast, Renqing Mangjue had no significant effect on the proliferation of normal GES-1 cells, but significantly inhibited the proliferation of MC cells (P<0.01) and markedly reduced their migratory capacity (P<0.01). Moreover, it also increased the mRNA expression level of E-cadherin during the EMT process (P<0.05), while inhibiting the expression of both N-cadherin and the transcription factor Snail mRNA (P<0.05, P<0.01). Network predictions suggested that Renqing Mangjue may prevent gastric cancer precursors through modulating the cGMP/PKG and MAPK/ERK signaling pathways. Furthermore, Western blot results indicated that Renqing Mangjue upregulated the expression of PKG and NPRB (B-type natriuretic peptide receptor) proteins in the cGMP/PKG pathway (P<0.01), while downregulating the expression of the downstream proteins MEK and ERK (P<0.05, P<0.01). ConclusionIn summary, Renqing Mangjue can prevent gastric cancer precursors by inhibiting the proliferation and migration of malignant transformed GES-1 cells, thereby delaying the EMT process. The underlying mechanisms may be related to the activation of the cGMP/PKG pathway and the inhibition of the MEK/ERK signaling pathway.

Objective:
To investigate the changes in oropharyngeal airway parameters and hyoid position in skeletal ClassⅡ adult female patients with different vertical skeletal types who were treated with maxillary anterior teeth retraction with maximum anchorage, and to provide a reference for orthodontic clinical diagnosis and treatment.
Methods:
This study was reviewed and approved by the Medical Ethics Committee, and informed consent was obtained from patients. Sixty adult female patients with skeletal ClassⅡ were selected and divided into a skeletal ClassⅡ normodivergent group and a skeletal ClassⅡ hyperdivergent group based on the patients’ mandibular plane angle. In both groups, the bilateral maxillary first premolars were extracted and the maxillary anterior teeth were retracted with maximum anchorage. Cone beam CT(CBCT) images were collected before and after treatment, and three-dimensional measurement software was used to analyze oropharyngeal airway-related parameters.
Results:
After retraction of the maxillary anterior teeth with maximum anchorage, the 10 parameters related to the oropharyngeal airway did not exhibit statistically significant differences in the normodivergent group (P>0.05), but the perpendicular distance from the highest point of the hyoid bone to the vertical line passing through the sella (H-X) value decreased (P<0.001). In the hyperdivergent group, the oropharyngeal area at the level of the epiglottis tip (OPA-E), anterior-posterior diameters of the oropharynx at the level of the epiglottis tip (E-AP), most constricted axial area of the oropharynx (OPA-MCA), and anterior-posterior diameters of MCA area of the oropharynx (MCA-AP) decreased after treatment (P<0.001). In addition, the oropharyngeal volume (OPV) decreased after treatment (P<0.05), and the perpendicular distance from the highest point of the hyoid bone to the horizontal line passing through the sella (H-Y) and the highest point of the hyoid bone to the epiglottis base (H-Eb) values increased after treatment (P<0.05).
Conclusion
After retraction of the maxillary anterior teeth with maximum anchorage, there is no change in the oropharyngeal airway in skeletal ClassⅡ normodivergent female adult patients, while skeletal ClassⅡhyperdivergent female adult patients have a risk of reduction in the oropharyngeal airway after maximuim anchorage retraction of the maxillary anterior teeth.

Based on the high-fat diet-induced hyperlipidemia rat model, this study aimed to evaluate the lipid-lowering effect of Arisaema Cum Bile and explore its mechanisms, providing experimental evidence for its clinical application. Biochemical analysis was used to detect serum levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), triglycerides(TG), and total cholesterol(TC) to assess the lipid-lowering activity of Arisaema Cum Bile. Additionally, 16S rDNA sequencing and metabolomics techniques were employed to jointly elucidate the lipid-lowering mechanisms of Arisaema Cum Bile. The experimental results showed that high-dose Arisaema Cum Bile(PBA-H) significantly reduced serum ALT, AST, LDL-C, TG, and TC levels(P<0.01), and significantly increased HDL-C levels(P<0.01). The effect was similar to that of fenofibrate, with no significant difference. Furthermore, Arisaema Cum Bile significantly alleviated hepatocyte ballooning and mitigated fatty degeneration in liver tissues. As indicated by 16S rDNA sequencing results, PBA-H significantly enhanced both alpha and beta diversity of the gut microbiota in the model rats, notably increasing the relative abundance of Akkermansia and Subdoligranulum species(P<0.01). Liver metabolomics analysis revealed that PBA-H primarily regulated pathways involved in arachidonic acid metabolism, vitamin B_6 metabolism, and steroid biosynthesis. In summary, Arisaema Cum Bile significantly improved abnormal blood lipid levels and liver pathology induced by a high-fat diet, regulated hepatic metabolic disorders, and improved the abundance and structural composition of gut microbiota, thereby exerting its lipid-lowering effect. The findings of this study provide experimental evidence for the clinical application of Arisaema Cum Bile and the treatment of hyperlipidemia.

Traditional Chinese medicine(TCM) capable of clearing heat and removing toxin is most commonly used in clinical practice and has the effect of removing fire-heat and toxin. Studies have shown that most of the Ilex plants have the effect of clearing heat and removing toxin, among which the varieties of I. cornuta, I. pubescens, I. rotunda, I. latifolia, and I. chinensis are most widely used. These plants generally contain triterpenoids and their glycosides, alkaloids, flavonoids, phenylpropanoids, and other chemical components, especially pentacyclic triterpenoids. According to their skeletons, pentacyclic triterpenoids can be divided into the oleanane type, the ursane type, the lupinane type, etc. Among them, ursane-type components are the most abundant, and 136 species have been found so far. These components have been proved to have pharmacological effects such as anti-inflammatory, anti-tumor, hypolipidemic, anti-thrombosis, cardiomyocyte-protective, antibacterial, and hepatoprotective effects. Therefore, this paper systematically reviews the domestic and foreign literature on Ilex plants with a focus on the research progress on pentacyclic triterpenoids and their pharmacological activities, aiming to provide reference for the development of TCM resources with the effect of clearing heat and removing toxin.

This study aims to explore the effects and action mechanisms of the active ingredients in Buyang Huanwu Decoction(BYHWD), namely tetramethylpyrazine(TMP) and hydroxy-safflor yellow A(HSYA), on oxygen-glucose deprivation/reglucose-reoxygenation(OGD/R)-induced inflammation and oxidative stress of microglia(MG). Network pharmacology was used to screen the effective monomer ingredients of BYHWD and determine the safe concentration range for each component. Inflammation and oxidative stress models were established to further screen the best ingredient combination and optimal concentration ratio with the most effective anti-inflammatory and antioxidant effects. OGD/R BV2 cell models were constructed, and BV2 cells in the logarithmic growth phase were divided into a normal group, a model group, an HSYA group, a TMP group, and an HSYA + TMP group. Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of inflammatory cytokines such as interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α), and interleukin-6(IL-6). Oxidative stress markers, including superoxide dismutase(SOD), nitric oxide(NO), and malondialdehyde(MDA), were also measured. Western blot was used to analyze the protein expression of both inflammation-related pathway [Toll-like receptor 4(TLR4)/nuclear factor-kappa B(NF-κB)] and oxidative stress-related pathway [nuclear factor erythroid 2-related factor 2(Nrf2)/heme oxygenase-1(HO-1)]. Immunofluorescence was used to assess the expression of proteins such as inducible nitric oxide synthase(iNOS) and arginase-1(Arg-1). The most effective ingredients for anti-inflammatory and antioxidant effects in BYHWD were TMP and HSYA. Compared to the normal group, the model group showed significantly increased levels of IL-1β, TNF-α, IL-6, NO, and MDA, along with significantly higher protein expression of NF-κB, TLR4, Nrf2, and HO-1 and significantly lower SOD levels. The differences between the two groups were statistically significant. Compared to the model group, both the HSYA group and the TMP group showed significantly reduced levels of IL-1β, TNF-α, IL-6, NO, and MDA, lower expression of NF-κB and TLR4 proteins, higher levels of SOD, and significantly increased protein expression of Nrf2 and HO-1. Additionally, the expression of the M1-type MG marker iNOS was significantly reduced, while the expression of the M2-type MG marker Arg-1 was significantly increased. The results of the HSYA group and the TMP group had statistically significant differences from those of the model group. Compared to the HSYA group and the TMP group, the HSYA + TMP group showed further significant reductions in IL-1β, TNF-α, IL-6, NO, and MDA levels, along with significant reductions in NF-κB and TLR4 protein expression, an increase in SOD levels, and elevated Nrf2 and HO-1 protein expression. Additionally, the expression of the M1-type MG marker iNOS was reduced, while the M2-type MG marker Arg-1 expression increased significantly in the HSYA + TMP group compared to the TMP or HSYA group. The differences in the results were statistically significant between the HSYA + TMP group and the TMP or HSYA group. The findings indicated that the combined use of HSYA and TMP, the active ingredients of BYHWD, can effectively inhibit OGD/R-induced inflammation and oxidative stress of MG, showing superior effects compared to the individual use of either component.

Traditional Chinese medicine(TCM) decoction pieces are a core carrier for the inheritance and innovation of TCM, and their quality and safety are critical to public health and the sustainable development of the industry. Conventional quality control models, while having established a well-developed system through long-term practice, still face challenges such as relatively long inspection cycles, insufficient objectivity in characterizing complex traits, and urgent needs for improving the efficiency of integrating multidimensional quality information when confronted with the dual demands of large-scale production and precision quality control. With the rapid development of artificial intelligence, machine learning can deeply analyze multidimensional data of the morphology, spectroscopy, and chemical fingerprints of decoction pieces by constructing high-dimensional feature space analysis models, significantly improving the standardization level and decision-making efficiency of quality evaluation. This article reviews the research progress in the application of machine learning in the processing, production, and rapid quality evaluation of TCM decoction pieces. It further analyzes current challenges in technological implementation and proposes potential solutions, offering theoretical and technical references to advance the digital and intelligent transformation of the industry.

Several types of arthritis share the common feature that the generation of inflammatory mediators leads to joint cartilage degradation. However, the shared mechanism is largely unknown. H2BK120ub1 was reportedly involved in various inflammatory diseases but its role in the shared mechanism in inflammatory joint conditions remains elusive. The present study demonstrated that levels of cartilage degradation, H2BK120ub1, and its regulator WW domain-containing adapter protein with coiled-coil (WAC) were increased in cartilage in human rheumatoid arthritis (RA) and osteoarthritis (OA) patients as well as in experimental RA and OA mice. By regulating H2BK120ub1 and H3K27me3, WAC regulated the secretion of inflammatory and cartilage-degrading factors. WAC influenced the level of H3K27me3 by regulating nuclear entry of the H3K27 demethylase KDM6B, and acted as a key factor of the crosstalk between H2BK120ub1 and H3K27me3. The cartilage-specific knockout of WAC demonstrated the ability to alleviate cartilage degradation in collagen-induced arthritis (CIA) and collagenase-induced osteoarthritis (CIOA) mice. Through molecular docking and dynamic simulation, doxercalciferol was found to inhibit WAC and the development of cartilage degradation in the CIA and CIOA models. Our study demonstrated that WAC is a key factor of cartilage degradation in arthritis, and targeting WAC by doxercalciferol could be a viable therapeutic strategy for treating cartilage destruction in several types of arthritis.

Probiotics play a crucial role in colon cancer treatment by metabolizing prebiotics to generate short-chain fatty acids (SCFAs). Colon cancer patients are frequently propositioned to supplement with probiotics to enhance the conversion and utilization of prebiotics. Nevertheless, the delivery and colonization of probiotics is hindered by the harsh conditions of gastrointestinal tract (GIT). Here, we devised a straightforward yet potent modified prebiotic-based "shield" (Gelatin-Inulin, GI), employing dietary inulin and natural polymer gelatin crosslinked via hydrogen bonding for enveloping Lactobacillus reuteri (Lr) to formulate synbiotic hydrogel capsules (Lr@Gl). The GI "shield" serves as a dynamic barrier, augmenting the resistance of Lr to gastric acid and facilitating its bioactivity and adherence in the GIT, synergizing with Lr to elicit an anti-tumor effect. Simultaneously, Lr@GI demonstrates anti-tumor effects by depleting glutathione to release reactive oxygen species, accompanied by the activation of NLRP3 (NOD-like receptor family pyrin domain containing 3), and the induction M1 macrophage polarization. Furthermore, Lr@GI can not only promote the recovery of intestinal barrier but also regulate intestinal flora, promoting the production of SCFAs and further exerting anti-tumor effect. Crucially, Lr@GI also potentiates the anti-tumor effect of 5-Fluorouracil. The construction and synergistic anti-tumor mechanism of synbiotic hydrogel capsules system provide valuable insights for gut microbial tumor therapy.
