It is believed that diabetes complicated with coronary heart disease is closely related to the functional interplay of the heart, spleen, and kidneys. This paper proposed the concept of the heart-spleen-kidney as a unified system for understanding and treating the disease. At the early stage, spleen and kidney deficiency leads to the internal accumulation of phlegm, dampness, and turbid lipids, causing impaired blood circulation and vascular obstruction, so treatment should focus on tonify the kidneys and strengthening the spleen, activating blood circulation and resolving stasis, using the self-prescribed Tangxin Maiwen Formula (糖心脉温方). As the disease progresses, further decline of spleen and kidney function results in inadequate nourishment of the heart, leading to blood stasis and the accumulation of phlegm, dampness, and turbid lipids, which may transform into pathogenic heat and toxins, causing heart damage, then treatment should emphasize on boosting qi and nourishing yin, clearing heat, activating blood and resolving toxins, using the self-prescribed Tangxin Maiqing Formula (糖心脉清方). In advanced stages, three zang organs, the heart, spleen, and kidneys, become severely impaired, leading to mental activity fail to be nourished and abnormal cognitive functions, so treatment should focus on harmonizing the three zang organs simultaneously, using the self-prescribed Yunpi Tiaoxin Decoction (运脾调心汤). This approach aims to provide a clinical framework for the diagnosis and treatment of diabetes with coronary heart disease.

This article summarized clinical experience in differentiating and treating non-obstructive hypertrophic cardiomyopathy (HCM) based on the concept of nourishing the heart and softening the hardness. It is considered that HCM belongs to the category of "heart accumulation", with the fundamental cause being depletion of the spleen and kidney, and phlegm-stasis accumulation, as well as qi-yin exhaustion, serving as the manifestations. Spleen and kidney depletion leads to the transformation of phlegm and stasis, which accumulate in the heart; over time, this phlegm-stasis accumulation consumes heart qi and yin, resulting in the heart being deprived of nourishment, which eventually leads to the damage to both the function and structure of heart. Therefore, the method of nourishing the heart and softening the hardness is proposed for the treatment of non-obstructive HCM. Emphasis is placed on softening hardness and dissipating masses throughout the entire treatment process, often using Modified Siwei Ruanjian Formula (四味软坚方加减). During periods with prominent symptoms, the main treatment is boosting qi and nourishing yin to soften hardness and dissipate masses with self-made Yuxin Ruanjian Formula (自拟育心软坚方) in modifications; in stable periods, the main treatment is boosting kidney and fortifying spleen to soften hardness and dissipate masses with self-made Pishen Tongzhi Formula (脾肾同治方) in modifications.

ObjectiveTo investigate the role of mature-tRNA-Asp-GTC and pre-tRNA-Arg-TCT in the ferroptosis phenotype of ovarian cancer (OC) cells and the regulatory mechanism of gypenoside L (Gyp-L) on mature-tRNA-Asp-GTC and pre-tRNA-Arg-TCT in OC cells. MethodsThe proliferation of human ovarian adenocarcinoma OVCAR3 cells was detected by cell counting kit-8 (CCK-8) assay, and the half-maximal inhibitory concentration (IC50) values of cisplatin (DDP), Gyp-L, and DDP in the presence of Gyp-L were calculated to determine the intervention concentration for subsequent experiments. Cell cloning assay and scratch assay reflected the proliferation and migration ability of OVCAR3 cells. PANDORA-seq small RNA sequencing was used to detect the differentially expressed transfer RNA-derived small RNAs (tsRNAs) in the cells after Gyp-L intervention, and the corresponding target genes of the tsRNAs were found by the RNAhybrid software. Malondialdehyde (MDA), glutathione (GSH), and lipid peroxide (LPO) levels were measured by colorimetry or enzyme linked immunosorbent assay (ELISA) method, Fe2+ content by FerroOrange fluorescent probe, and reactive oxygen species (ROS) content by DCFH-DA fluorescent probe to reflect the occurrence of ferroptosis in OVCAR3 cells. OVCAR3 cells were divided into a control group, a 50 µmol·L-1 Gyp-L group, and a 100 µmol·L-1 Gyp-L group. Quantitative real-time polymerase chain reaction (PCR) was performed to detect the expression of mature-tRNA-Asp-GTC, mature-tRNA-Leu-CAA, mature-mt_tRNA-Tyr-GTA_5_end, mature-tRNA-Val-CAC, mature-mt_tRNA-Glu-TTC, pre-tRNA-Arg-TCT, mature-tRNA-Asn-GTT, hydroxymethylbilane synthase (HMBS), Wnt, β-catenin, glutathione peroxidase 4 (GPX4), Kelch-like ECH-associated protein 1 (KEAP1), nuclear factor erythroid 2-related factor 2 (Nrf2), activating transcription factor 3 (ATF3), cystine/glutamate antiporter xCT, lysophosphatidylcholine acyltransferase 3 (LPCAT3), and arachidonate 15-lipoxygenase (ALOX15). Western blot was performed to detect the expression of HMBS, Wnt, β-catenin, GPX4, KEAP1, Nrf2, ATF3, xCT, LPCAT3, and ALOX15 proteins. ResultsThe 50 µmol·L-1 Gyp-L, 100 µmol·L-1 Gyp-L, DDP, 50 µmol·L-1 Gyp-L+DDP, and 100 µmol·L-1 Gyp-L+DDP groups showed significantly inhibited proliferation and migration of OVCAR3 cells (P<0.05) and exacerbated cell ferroptosis as reflected by the increase in the content of ROS, MDA, LPO, and Fe2+, as well as a decrease in the content of GSH (P<0.05). Compared with the control group, Gyp-L effectively interfered with the expression of 25 tsRNAs in OVCAR3 cells (P<0.05, |log2Fc|>1). Pre-tRNA-Arg-TCT/HMBS/Wnt/β-catenin/GPX4, pre-tRNA-Arg-TCT/KEAP1/NRF2/xCT, mature-tRNA-Asp-GTC/ATF3/KEAP1/NRF2/xCT, and mature-tRNA-Asp-GTC/LPCAT3/ALOX15 axial expression was significantly aberrant after Gyp-L intervention (P<0.05). ConclusionThe pre-tRNA-Arg-TCT/HMBS/Wnt/β-catenin/GPX4, pre-tRNA-Arg-TCT/KEAP1/Nrf2/xCT, mature-tRNA-Asp-GTC/ATF3/KEAP1/Nrf2/xCT, and mature-tRNA-Asp-GTC/LPCAT3/ALOX15 signaling pathways are involved in OC development. Gyp-L inhibits OC development by activating OVCAR3 cell ferroptosis onset mainly through the mature-tRNA-Asp-GTC/ATF3/KEAP1/Nrf2/xCT and mature-tRNA-Asp-GTC/LPCAT3/ALOX15 signaling axes.

ObjectiveWith the epidermal growth factor receptor(EGFR)/Signal Transducers and Activators of Transcription(STAT3)/Hexokinase 2(HK2) signaling pathway in atherosclerosis (AS) and ovarian cancer (OC) as the entry point, this paper discusses the molecular mechanism of Gypenoside L (Gyp-L) treating AS and OC with different diseases, provides a new perspective and theoretical basis for TCM treating AS and OC with EGFR-STAT3-HK2 pathway, and enriches the scientific connotation of the theory of "cytoskeleton in the heart". MethodsCCK-8 was used to detect the proliferation of HUVEC and OVCAR-3 cells, in order to determine the intervention concentration for subsequent experiments. The colorimetric method was used to detect the NO content in HUVEC and the contents of pyruvate and LDH in two cell lines. Cell cloning experiments and scratch experiments reflect the proliferation and migration ability of OVCAR-3 cells. Western blot was used to detect the expression levels of relevant proteins. Furthermore, two cell models overexpressing EGFR were constructed and co treated with Gyp-L. HUVEC cells were divided into control, ox-LDL, OE-NC, OE-EGFR, OE-NC+Gyp-L, and OE-EGFR+Gyp-L group. OVCAR-3 cells were divided into control, OE-NC, OE-EGFR , OE-NC+Gyp-L, and OE-EGFR+Gyp-L group. The colorimetric method was used to detect the NO content in HUVEC and the contents of pyruvate and LDH in two cell lines. Western blot was used to detect the expression levels of EGFR-STAT3-HK2 pathway related proteins. Cell cloning experiments and scratch experiments reflect the proliferation and migration ability of OVCAR-3 cells. ResultsGyp-L can significantly reduce the NO content of HUVEC and the pyruvate and LDH content of two cell lines (P<0.05); Inhibit the proliferation and migration ability of OVCAR-3 cells; Reduce the expression levels of EGFR/STAT3/HK2 pathway related proteins in HUVEC and OVCAR-3 cell lines (P<0.05), and inhibit the glycolysis pathway. ConclusionGyp-L can inhibit glycolysis in HUVEC and OVCAR-3 cells through the EGFR/STAT3/HK2 pathway,thereby suppressing the occurrence and development of AS and OC.

ObjectiveTo explore the effect of gypenosides (GPs) on liver lipid deposition in metabolism-associated fatty liver disease (MAFLD) mice and its mechanism based on classical/non-classical ferroptosis. MethodsEight male C57BL/6 mice in a blank group and 32 male apolipoprotein E gene knockout (ApoE-/-) mice were randomly divided into a model group, a low-dose GPs (GPs-L) group, a high-dose GPs (GPs-H) group, and a simvastatin (SV) group. Starting from the second week, mice in the blank group were given a maintenance diet, and the other four groups were fed a high-fat diet daily. After eight weeks of feeding, mice in the GPs-L and GPs-H groups were given GPs of 1.487 mg·kg-1·d-1 and 2.973 mg·kg-1·d-1, respectively, and mice in the SV group were given simvastatin of 2.275 mg·kg-1·d-1. Mice in the blank group and the model group were given saline of equal volume by gavage for four weeks. The content of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) in the serum of mice in each group was detected by an automatic biochemical analyzer. The level of non-esterified fatty acid (NEFA) and TG in the mouse liver was measured by the kit. The change in liver tissue structure and lipid deposition was observed by hematoxylin-eosin (HE) and oil red O staining. The levels of coenzyme Q10 (CoQ10), glutathione (GSH), malondialdehyde (MDA), and Fe2+ in serum, as well as nicotinamide adenine dinucleotide phosphate [NAD(P)H] in the liver were detected by enzyme-linked immunosorbent assay (ELISA). The expression of ferroptosis suppressor protein 1 (FSP1) in the liver of mice was observed by the immunohistochemical (IHC) method, and the expression of genes and proteins related to classical and non-classical ferroptosis pathways was analyzed by real-time polymerase chain reaction (Real-time PCR) and Wes automated protein expression analysis system. ResultsCompared with those in the blank group, the levels of TC, TG, LDL-C, ALT, and AST in serum and TG and NEFA in the liver in the model group were significantly increased, and the level of HDL-C in serum was significantly decreased (P<0.01). The liver tissue structure changed, and there were fat vacuoles of different sizes and a large number of red lipid droplets, with obvious lipid deposition. The level of CoQ10 and GSH in serum and NADH in the liver were significantly decreased, while the level of MDA and Fe2+ in serum was significantly increased (P<0.01). The mRNA and protein expressions of cystine/glutamate transporter (xCT/SLC7A11), glutathione peroxidase (GPX4), p62, nuclear factor E2-related factor 2 (Nrf2), and FSP1 were significantly decreased, and the mRNA and protein expressions of tumor antigen (p53), spermidine/spermine N1-acetyltransferase 1 (SAT1), arachidonate 15-lipoxygenase (ALOX15), and Kelch-like epichlorohydrin-associated protein-1 (Keap1) were significantly increased (P<0.01). Compared with those in the model group, the level of TC, TG, LDL-C, ALT, and AST in serum and TG and NEFA in the liver of mice in the GPs-L, GPs-H, and SV groups were decreased, while the level of HDL-C in serum was significantly increased (P<0.05, P<0.01). The liver tissue structure and lipid deposition were improved. The levels of CoQ10 and GSH in serum and NADH in the liver were significantly increased, while the levels of MDA and Fe2+ in serum were significantly decreased (P<0.05, P<0.01). The mRNA and protein expressions of xCT, GPX4, p62, Nrf2, and FSP1 were significantly increased, while the mRNA and protein expressions of p53, SAT1, ALOX15, and Keap1 were significantly decreased (P<0.05, P<0.01). ConclusionGPs can interfere with liver lipid deposition in MAFLD mice through classical/non-classical ferroptosis pathways.

OBJECTIVE To systematically summarize the working model of pharmacy consultation in medical institutions in China, and to provide reference for the normalization of process, standardization of content and homogenization of services of pharmacy consultation. METHODS A systematic search of Chinese and English literature databases was conducted to incorporate the literature on the working model of pharmacy consultation published by medical institutions in China. Two researchers screened and extracted the key information, and ultimately conducted qualitative summary and descriptive analysis. RESULTS Based on the included 11 articles, the pharmacy consultation working models were explored by clinical pharmacists in China. The contents of consultation mainly involved anti-infection, parenteral nutrition, cancer pain, etc. The general concept of pharmacy consultation should refer to the constructed flowchart, specific consultation problems could refer to the pathway, mind map, or decision tree and other framework guidance to carry out the work. Finally, consultation opinions could be written according to the consultation system or specialty consultation templates, and the adoption of a new working model (such as pharmacist active consultation) could also promote the number and acceptance rate of pharmacy consultation. CONCLUSIONS A series of working models of pharmacy consultation have been initially explored in medical institutions in China. However, it is not yet perfect and lacks a unified quality control and evaluation system for pharmacy consultation, which should be the focus of future research and practice.
