RESUMEN

OBJECTIVES: To explore the mechanism of core points in acupuncture and moxibustion treatment for epilepsy by using data mining technique, so as to provide a reference for clinical practice and experimental research. METHODS: The data comes from relevant documents collected from CNKI, Wanfang, SinoMed, VIP, PubMed, Embase, Cochrane Library, EBSCO, Web of Science databases. The selected acupoints were analyzed in descriptive statistics, high-frequency acupoints group and core acupoint prescription. Further, potential target mining, "core acupoint prescription-target-epilepsy" network construction, protein-protein interactions (PPI) network establishment and core target extraction, gene ontology (GO) and KEGG gene enrichment analysis of the core acupoint prescription were carried out to predict its anti-epileptic potential mechanism. RESULTS: A total of 122 acupoint prescriptions were included. The core acupoint prescriptions were Baihui (GV20), Hegu (LI4), Neiguan (PC6), Shuigou (GV26) and Taichong (LR3). 277 potential targets were identified, among which 134 were shared with epilepsy. The core targets were extracted by PPI network topology analysis, including signal transducer and activator of transcription 3, tumor necrosis factor (TNF), interleukin (IL)-6, protein kinase B1, c-Jun N-terminal kinase, brain-derived neurotrophic factor, tumor protein 53, vascular endothelial growth factor A, Caspase-3, epidermal growth factor receptor, etc. The main anti-epileptic pathways of the core acupoints were predicted by KEGG enrichment, including lipid and atherosclerosis, neurodegeneration, phosphatidylinositol-3-kinase/protein B kinase signaling pathway, mitogen-activated protein kinase signaling pathway, cyclic adenosine monophosphate signaling pathway, TNF signaling pathway, IL-17 signaling pathway, hypoxia-inducible factor-1 signaling pathway, apoptosis, etc., involving neuronal death, synaptic plasticity, oxidative stress, inflammation and other related biological process. CONCLUSIONS: The core acupoint prescription of acupuncture and moxibustion intervention for epilepsy can act on multiple targets and multiple pathways to exert anti-epileptic effects, which can provide a theoretical basis for further clinical application and mechanism research.

RESUMEN

PURPOSE: Music intervention is commonly used as a non-pharmacologic therapeutic modality to alleviate anxiety in perioperative patients. This study aimed to assess the sedative and anxiolytic effects of music on elderly patients receiving transurethral resection of prostate (TURP) under spinal anesthesia. METHODS: This was a prospective randomized controlled trial on patients who aged over 60 and received TURP under spinal anesthesia. Participants were randomized to the music group or the control group (no music). The primary outcome was perioperative BIS values, and the secondary outcomes were patient's perioperative anxiety levels, heart rate (HR), blood pressure, and patient satisfaction score. RESULTS: A total of 82 patients were analyzed. The perioperative BIS values in the music group were significantly lower than those of the control group at almost all time points (P < 0.001), as well as showed a significant reduction compared with baseline (P < 0.001), whereas the control group did not. In comparison with the control group, systolic blood pressure (SBP) significantly decreased in the music group at the beginning (mean difference, - 8.0 mmHg; 95% CI - 15.70 to 0.35; P = 0.041) and the 60th minute (mean difference, - 7.9 mmHg; 95% CI - 15.30 to 0.51; P = 0.037) of TURP. Furthermore, compared with baseline within the music group, diastolic blood pressure (DBP) and HR significant reduced at whole time points (P < 0.05), yet the control group not. CONCLUSION: Music intervention effectively provided slight sedation for elderly patients when undergoing TURP under spinal anesthesia without sedatives.

RESUMEN

During the long-term orbital flight, exposure to microgravity negatively affects the astronauts' development of cognition, characterized by learning and memory decline. Gastrodia elata Blume (GEB) has a significant protective effect on cognitive impairment and has been used in Asia for centuries as a functional product. A previous study demonstrated that GEB could improve memory loss in mice caused by circadian rhythm disorders. However, the effects of GEB on cognitive dysfunction caused by weightless environments have not been investigated. In this study, mice received daily treatment with GEB (0.5, 1 g·kg-1d-1, i.g) and Huperzine A(Hup, 0.1 mg·kg-1d-1, i.g) orally until the end of the behavioral test (New object recognition test (NORT). Malondialdehyde (MDA) and nitric oxide (NO) levels were detected by kits, and expression of brain-derived neurotrophic factor (BDNF), protein kinase B (AKT), phosphorylated Akt (P-AKT), synaptophysin (SYN) and postsynaptic density 95(PSD95) in hippocampus were detected by western blotting. The results show that administration of GEB (0.5, 1 g·kg-1d-1, i.g) and Hup (0.1 mg·kg-1d-1, i.g) remarkably reverse HLS-induced learning and behavioral memory disorders, which were associated with significant changes in MDA and NO levels. Additionally, the protein expressions of BDNF, P-AKT/AKT, SYN, and PSD95 were significantly increased in the hippocampus. In summary, our findings will improve the reference for developing GEB as a functional product that improves memory decline.

RESUMEN

OBJECTIVE: To investigate the effect and potential mechanism of dihydromyricetin (Dmy) on H9C2 cell proliferation, apoptosis, and autophagy. METHODS: H9C2 cells were randomly divided into 7 groups, namely control, model, EV (empty pCDH-CMV-MCS-EF1-CopGFP-T2A-Puro vector), IV (circHIPK3 interference), Dmy (50 µ mol/L), Dmy+IV, and Dmy+EV groups. Cell proliferation and apoptosis were detected by cell counting kit-8 assay and flow cytometry, respectivley. Western blot was used to evaluate the levels of light chain 3 II/I (LC3II/I), phospho-phosphoinositide 3-kinase (p-PI3K), protein kinase B (p-AKT), and phospho-mammalian target of rapamycin (p-mTOR). The level of circHIPK3 was determined using reverse transcriptase polymerase chain reaction. Electron microscopy was used to observe autophagosomes in H9C2 cells. RESULTS: Compared to H9C2 cells, the expression of circHIPK in H9C2 hypoxia model cells increased significantly (P<0.05). Compared to the control group, the cell apoptosis and autophagosomes increased, cell proliferation rate decreased significantly, and the expression of LC3 II/I significantly increased (all P<0.05). Compared to the model group, the rate of apoptosis and autophagosomes in IV, Dmy, and Dmy+IV group decreased, the cell proliferation rate increased, and the expression of LC3 II/I decreased significantly (all P<0.05). Compared to the control group, the expressions of p-PI3K, p-AKT, and p-mTOR in the model group significantly reduced (P<0.05), whereas after treatment with Dmy and sh-circHIPK3, the above situation was reversed (P<0.05). CONCLUSION: Dmy plays a protective role in H9C2 cells by inhibiting circHIPK expression and cell apoptosis and autophagy, and the mechanism may be related to PI3K/AKT/mTOR pathway.

RESUMEN

BACKGROUND: Cardiac fibrosis is a major structural change observed in the heart of patients with type 2 diabetes mellitus (T2DM), ultimately resulting in heart failure (HF). Suppression of inflammation is an effective therapeutic strategy for treating cardiac fibrosis and HF. Gentiopicroside (GPS), the primary component of Gentiana manshurica Kitagawa, possess potent anti-inflammatory activity. However, its cardioprotective role remains elusive. PURPOSE: We explored the potential cardioprotective role of GPS in T2DM rats and its underlying mechanisms. METHODS: T2DM rats built by high-fat diet and streptozotocin were orally administered 25, 50, or 100 mg/kg GPS, daily for 8 weeks. The positive control drug was Metformin (200 mg/kg/day). Primary cardiac fibroblasts (CFs) were induced by high glucose (30 mM) and subsequently treated with GPS (100 µM). Cardiac function and pathological changes were analyzed using echocardiography and histological staining. Potential targets of GPS were predicted using Molecular docking. Real-time PCR as well as western blotting were applied to verify the expression of objective genes. RESULTS: All three doses reduced fasting blood glucose levels, but only 50 and 100 mg/kg GPS improved cardiac function and alleviated inflammation and fibrosis in T2DM rats. GPS (100 mg/kg) exhibited a better effect, similar to that of metformin. Mechanistically, binding between GPS and the MH2 domain of Smad3 blocked high glucose-induced Smad3 phosphorylation, thus attenuating inflammation, oxidative stress, and activation in CFs. CONCLUSION: We, for the first time, demonstrated that GPS improved cardiac function in T2DM rats and elucidated the underlying mechanism through which GPS targeted Smad3 phosphorylation to suppress inflammation and activation in CFs, thereby revealing the potential application of GPS in HF therapy.

RESUMEN

BACKGROUND: Botrychium schaffneri Underw. has been popularly consumed since ancient times as a traditional medicine in China to treat whooping cough, bronchial asthma, and febrile convulsive twitch disease. This led us to investigate whether Botrychium schaffneri Underw. extract (BSE) may be effective against lung cancer, especially non-small cell lung carcinoma (NSCLC). METHODS: In this study, we extracted the ethanolic root extract of the grass, Botrychium schaffneri Underw. In vitro study, the change of NCI-H1299 cell proliferation was observed with CCK8 and MTT assays. Cell apoptosis was assessed using a kit based on staining with FITC-conjugated annexin V. In vivo study, we establish a stable animal model of NSCLC in nude mice, tumor volume and weight was measured twice a week. We conduct gene microarray screened for differentially expressed genes (DEGs), between NCI-H1299 cells treated by BSE or not. Then the DEGs were functionally annotated and path enriched. RESULTS: It was revealed that BSE significantly suppressed NSCLC cell proliferation (IC50 134 µg/mL) and induced apoptosis. It also slowed tumor growth without affecting body weight, and a dose of 25 g/kg led to significantly smaller tumors than in control animals (13.85±3.36 vs. 23.40±6.05, P=0.044). Apoptosis-related protein direct IAP Binding protein with low PI (DIABLO) expression was up-regulated by BSE, and DIABLO knockdown significantly attenuated the anti-tumor effects of the extract. CONCLUSIONS: In conclusion, BSE reduces the viability of NSCLC cells and promotes apoptosis, and these effects may be mediated by DIABLO.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Cimicifuga racemose is previously proved effective on nature menopausal syndrome (MPS). However, its clinical value in treating with MPS induced by luteinizing-hormone releasing hormone analogue (LHRH-a) therapy of pre-/peri-menopausal breast cancer patients is still unknown. AIM OF STUDY: This perspective randomised-design study is to investigate the effect and safety of cimicifuga racemosa on MPS induced by LHRH-a in breast cancer (clinical trial registered: NCT03339882). MATERIALS AND METHODS: Breast cancer patients planning for LHRH-a treatment were randomly divided into 2 groups. The control group which was being treated with the standard treatment of LHRH-a. The other group was being treated with Remifemin, the commercialized product of cimicifuga racemose extract, combined with LHRH-a, called Remifemin group. Our main endpoint was Kupperman menopause index (KMI). Hormone levels in peripheral blood and gynecological complications were also evaluated. RESULTS: Totally, 85 patients (42 in Remifemin group and 43 in control group) were enrolled in Zhejiang Cancer Hospital. At the 4th, 8th and 12th week after using LHRH-a, the KMI were all significantly lower in Remifemin group than in control group (P < 0.01), while the hormone levels, including estradiol (E2), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were similar in the two groups. In addition, the incidence of cervical cyst in Remifemin group was higher than that in control group (P = 0.02), and there was no significant difference in the other gynecological complications, including endometrial thickening, ovarian cyst or uterine fibroid (P > 0.05). CONCLUSIONS: Cimicifuga racemose is effective, oncological safe and reliable for treatment of MPS caused by LHRH-a in breast cancer.

RESUMEN

The pregnane X receptor (PXR) is a key regulator of CYP3A4, which is involved in catalyzing the metabolic conversion of a number of endogenous substrates. In this study, we screened 22 compounds isolated from traditional Chinese herbal medicines using luciferase reporter gene assays for inspecting their capabilities in inducing PXR-mediated transactivation of CYP3A4 expression. In addition, the mRNA and protein expressions of CYP3A4 and PXR as well as the enzymatic activites of CYP3A4 were analyzed by real-time PCR, Western blot analysis and UPLC-MS/MS-based metabolite assay in LS174T cells. Huperzine A, ligustrazine and oridonin were identified to be the inducers of CYP3A4. These compounds induced the CYP3A4 reporter luciferase activity, and up-regulated CYP3A4 mRNA and protein levels significantly. Besides, huperzine A, ligustrazine and oridonin significantly up-regulated enzymatic activities of CYP3A4. However, the three compounds showed no effects on PXR mRNA and protein expression. To our knowledge, it is the first identification of these three compounds as PXR activators to induce CYP3A4. These results indicate that huperzine A, ligustrazine and oridonin induced CYP3A4 expression and activation via PXR dependent pathways, and might contribute to drug-drug interactions.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Oridonin, the major terpene found in Rabdosia rubescens, is widely used as a dietary supplement or therapeutic drug. The effects of oridonin on drug processing genes, such as cytochrome P450 and nuclear receptors, were still unclear. Therefore, the present study investigated the influence of oridonin on the hepatic drug metabolizing system to evaluate the safety through its drug interaction potential. MATERIALS AND METHODS: In this study, eight-week-old male C57BL/6 mice were treated oridonin orally (0, 25, 50, 100, 200 mg/kg, i.g.) for 15 days. The effects of oridonin on major Cyps in mice livers were examined at both the mRNA and enzyme activity levels. RESULTS: In general, there are no significant influence of various dose of oridonin on mice liver function. However, oridonin significantly increased Cyps (1a, 2a, 2d, 2e, 2c and 3a family) mRNA expression. In addition, it could induce Cyps activity in microsome incubation at maximum dosage. To our knowledge, it is the first time to identify oridonin as a Cyps inducer in vivo. It also promotes the expression of CAR, PXR and POR. CONCLUSION: These results indicate that, if studies in mice extrapolate to humans by orthologous genes, oridonin appears to be a risk to herb-drug interactions due to its induction effects on drug processing genes expression and activation.

RESUMEN

AIM: Herbal products have been widely used, and the safety of herb-drug interactions has aroused intensive concerns. This study aimed to investigate the effects of phytochemicals on the catalytic activities of human CYP2D6(*)1 and CYP2D6(*)10 in vitro. METHODS: HepG2 cells were stably transfected with CYP2D6(*)1 and CYP2D6(*)10 expression vectors. The metabolic kinetics of the enzymes was studied using HPLC and fluorimetry. RESULTS: HepG2-CYP2D6(*)1 and HepG2-CYP2D6(*)10 cell lines were successfully constructed. Among the 63 phytochemicals screened, 6 compounds, including coptisine sulfate, bilobalide, schizandrin B, luteolin, schizandrin A and puerarin, at 100 µmol/L inhibited CYP2D6(*)1- and CYP2D6(*)10-mediated O-demethylation of a coumarin compound AMMC by more than 50%. Furthermore, the inhibition by these compounds was dose-dependent. Eadie-Hofstee plots demonstrated that these compounds competitively inhibited CYP2D6(*)1 and CYP2D6(*)10. However, their Ki values for CYP2D6(*)1 and CYP2D6(*)10 were very close, suggesting that genotype-dependent herb-drug inhibition was similar between the two variants. CONCLUSION: Six phytochemicals inhibit CYP2D6(*)1 and CYP2D6(*)10-mediated catalytic activities in a dose-dependent manner in vitro. Thus herbal products containing these phytochemicals may inhibit the in vivo metabolism of co-administered drugs whose primary route of elimination is CYP2D6.

RESUMEN

OBJECTIVE: To study the effects of Compound Salvia miltiorrhiza Injection (CSI) on aquaporin 3 (AQP3) expression in human amniotic epithelial cells (hAECs), and to explore its mechanisms for treating oligohydramnios. METHODS: The hAECs selected from 8 human term pregnancies with oligohydramnios and no other complications (as the test group)and 8 human term pregnancies with normal amniotic fluid volume (as the control group) were primarily cultured. The mRNA and protein expressions of AQP3 in hAECs were detected using reverse transcription-polymerase chain reaction and Western blot with various concentrations of CSI (0.000, 0.001, 0.010, 0.020, 0.060, and 0.100 mg/mL, respectively) at different time points (0, 6, 12,24, and 48 h, respectively). RESULTS: (1) Compared with the control group, the AQP3 expression was down-regulated in the test group (P < 0.05). (2) The AQP3 expression in the two groups reached the peak when the concentration of CSI was 0.010 mg/mL, showing statistical difference when compared with other concentrations (P < 0.05). (3) The AQP3 expression reached the peak when 0.010 mg/mL CSI acted for 12 h, showing statistical difference when compared with other concentrations (P < 0.05). (4) The AQP3 expression was up-regulated in the two groups when 0.010 mg/mL CSI acted for 12 h. But the up-regulated AQP3 expression was more obvious in the test group than in the control group (P < 0.05). CONCLUSIONS: CSI could regulate the AQP3 expression in hAECs. CSI showed more obvious effects on the AQP3 expression in hAECs of oligohydramnios human term pregnancies.

RESUMEN

Paeonol is an active compound isolated from traditional Chinese medicine, and has been shown to have anti-atherosclerosis, anti-inflammatory, antioxidant effects. The present investigation was undertaken to determine the suppression effects of paeonol on oxidized low-density lipoprotein (ox-LDL) induced endothelial cell line HUVEC apoptosis and to uncover some of the underlying mechanisms of these effects. Cell viability and lactate dehydrogenase (LDH) were measured to evaluate the cell injuries. Apoptosis was evaluated by Hoechst 33342 staining and flow cytometry. Intracellular reactive oxygen species (ROS) generation was detected by 2',7'-dichlorofluorescein diacetate (DCFH-DA). Real-time PCR was used to confirm the expression of LOX-1 mRNA. Western blotting was used to evaluate the protein expression of LOX-1 and Bcl-2, as well as caspase-3 cleavage, p38-mitogen-activated protein kinase (p38MAPK) phosphorylation. NF-κB nuclear translocation was detected by Western blotting and immunofluorescence. Caspase-3 activity was measured using a colorimetric protease assay kit. The results showed that ox-LDL significantly decreased cell viability and increased the LDH release, as well as the apoptotic rate (P<0.01). Pre-treatment of paeonol resulted in remarkable increase of cell viability, decrease of LDH release and cell apoptosis in a concentration-dependent manner. Besides, ox-LDL caused the up-regulation of LOX-1, the down-regulation of Bcl-2, the phosphorylation of p38MAPK, the translocation of NF-κB and the activation of caspase-3. Paeonol pre-treatment reversed these effects introduced by ox-LDL. Moreover, paeonol also showed its inhibition effects on ox-LDL induced ROS overproduction. These results indicate the preventive effects of paeonol on ox-LDL induced endothelial cell apoptosis. The effects might, at least partly, be obtained via inhibition of LOX-1-ROS- p38MAPK-NF-κB signaling pathway.
