Pharmacological Components and Mechanism Research on the Treatment of Myelosuppression after Chemotherapy with Danggui Jixueteng Decoction Based on Spectrum-Effect Relationships and Transcriptome Sequencing. ACS OMEGA 2024; 9:28926-28936. [PMID: 38973888 PMCID: PMC11223127 DOI: 10.1021/acsomega.4c03641] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Revised: 06/07/2024] [Accepted: 06/10/2024] [Indexed: 07/09/2024]
Abstract
Danggui Jixueteng decoction (DJD) has been used to treat anemia for many years and has been shown to be effective. However, the mechanism of action and effective components are yet unknown. We want to search for pharmacodynamic components in DJD with therapeutic effects on myelosuppression after chemotherapy (MAC), utilizing a spectrum-effect connection study based on gray relational analysis and partial least-squares regression analysis. Transcriptome sequencing (RNA-Seq) was used to investigate the mechanism by which DJD treats MAC. In this study, fingerprints of different batches of DJD (S1-S10) were established by ultraperformance liquid chromatography-mass spectrometry (UPLC-MS), after which the resulting shared peaks were screened and identified. A total of 21 common peaks were screened through the fingerprints of different batches of DJD, and the similarity of each profile was greater than 0.92. The 21 shared peaks were identified by comparison with the standard sample and searching on a MassLynx 4.1 workstation. The rat model of MAC was established by intraperitoneal injection of cyclophosphamide, and DJD treatment was carried out in parallel with the establishment of the model. White blood cell count, red blood cell count, platelet count, interleukin-3, hemoglobin concentration, granulocyte-macrophage colony-stimulating factor, and nucleated cell count were used as efficacy indicators. Pharmacodynamic results indicated that DJD could effectively improve the pharmacodynamic indices of MAC rats. The results of gray relational analysis demonstrated eight peaks with high correlation with efficacy, which were 2, 7, 10, 14, 15, 16, 18, and 21, and the partial least-squares regression analysis showed four peaks with variable importance in projection values greater than 1, which were 10, 12, 13, and 19. RNA-Seq was used to identify DEGs in rat bone marrow cells, Gene Ontology functional enrichment and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses of DEGs were performed. The genes related to the effects of DJD on MAC were mainly involved in the phosphatidylinositol 3-kinase/serine-threonine kinase (PI3K-Akt) signaling pathway, the mitogen-activated protein kinase signaling pathway, actin cytoskeleton regulation, focal adhesion, and Rap1 signaling pathways. The results of the RNA-Seq study were confirmed by a qPCR experiment. The effective compounds of DJD against MAC include albiflorin, paeoniflorin, gallopaeoniflorin, salvianolic acid H/I, albiflorin R1, salvianolic acid B, salvianolic acid E, benzoylpaeoniflorin, and C12H18N5O4. The mechanism by which DJD prevents and treats MAC might involve the control of the PI3K-Akt signaling pathway.

Abstract
BACKGROUND Modern medicine has no cure for the xerostomia caused by the early onset of Sjögren's syndrome. Mume Fructus is a common Chinese herbal medicine used to relieve xerostomia. However, the molecular mechanisms of the effects of Mume Fructus are unknown. In this study, network pharmacology and molecular docking were used to investigate the mechanisms of action of Mume Fructus on Sjögren's syndrome. MATERIALS AND METHOD The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform database was used to identify the active components and targets of Mume Fructus, and the UniProt database was used to identify the genes encoding these targets. SS-related targets were also identified from the GeneCards and OMIM databases. By finding the intersection of the targets of the compounds and the targets of Sjögren's syndrome, the predicted targets of Mume Fructus in the treatment of Sjögren's syndrome were obtained. Further investigation of the active compounds and their targets was carried out by constructing a network of "medicine-candidate compound-target-disease" using Cytoscape 3.7.2, the Protein-Protein Interaction network using the STRING database and Cytoscape 3.7.2, and key targets were identified by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis on R software. Finally, molecular docking was used to verify the affinity of the candidate compounds to the key targets. RESULTS Quercetin, beta-sitosterol, and kaempferol in Mume Fructus interact with AKT1, IL-6, IL-1B, JUN, CASP3, and MAPK8. These results suggest that Mume Fructus exerts its therapeutic effects on the peripheral gland injury of Sjögren's syndrome and its secondary cardiovascular disease and tumorigenesis through anti-inflammatory, anti-oxidant, and anti-tumor pathways. CONCLUSION With network pharmacology, this study systematically identified the main active components, targets, and specific mechanisms of the therapeutic effects of Mume Fructus on Sjögren's syndrome, providing both a theoretical basis and research direction for further investigations on Mume Fructus.

Kuo PY, Chen PH, Wu SH. Black hairy tongue treated with traditional Chinese medicine: A case report. Medicine (Baltimore) 2023; 102:e34430. [PMID: 37904483 PMCID: PMC10615480 DOI: 10.1097/md.0000000000034430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Accepted: 06/30/2023] [Indexed: 11/01/2023] Open
Abstract
RATIONALE Black hairy tongue (BHT) is a rare condition that is conventionally managed by discontinuing associated medications or habits and practicing good oral hygiene, including tongue brushing. Previous studies have indicated that black tongue coating is often associated with gastrointestinal discomfort, which traditional Chinese medicine (TCM) could be a potentially effective option for treating this condition with minimal side effects. We present a case of BHT diagnosed and treated within 2 weeks by using TCM methods. PATIENT CONCERNS A 73-year-old woman presented with a chief concern of a black tongue that had persisted for 2 weeks and was accompanied by thirst and diarrhea. These symptoms were initially observed during her hospitalization for the treatment of staghorn calculi, xanthogranulomatous pyelonephritis, and urosepsis. Using the "four diagnostic methods" of TCM, we observed that her tongue had a thick black coating surrounded by a thick white coating; her tongue was of medium size with tooth marks, and its body color was light red. DIAGNOSES, INTERVENTIONS, AND OUTCOMES On the basis of TCM theory, we made a clinical diagnosis of BHT and "spleen Qi deficiency with turbid dampness," which may have been caused by the antibiotic treatment during hospitalization. Subsequently, we administered a Chinese herbal medicine (CHM) formula comprising a combination of Wu-Ling-San () and a modification of Da-Yuan-Yin (). After 2 weeks of CHM treatment, the patient's BHT was nearly eliminated, and the thick white coating and the corresponding symptoms were ameliorated. After 4 weeks of CHM treatment, the BHT was completely resolved. LESSON AND CONCLUSION We present a case of BHT, a benign condition that may be caused by antibiotics. The literature does not contain reports on TCM-based diagnosis and treatment strategies for BHT. Using the 4 diagnostic methods of TCM, we observed that BHT was associated with gastrointestinal symptoms, which is consistent with the TCM theory. Moreover, CHM treatment rapidly relieved BHT and related symptoms without adverse events.

Xerostomia: From Pharmacological Treatments to Traditional Medicine-An Overview on the Possible Clinical Management and Prevention Using Systemic Approaches. Curr Oncol 2023; 30:4412-4426. [PMID: 37232794 DOI: 10.3390/curroncol30050336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 04/16/2023] [Accepted: 04/22/2023] [Indexed: 05/27/2023] Open
Abstract
Despite high incidence rates and severe complications, the management of xerostomia lacks clinical guidelines. The aim of this overview was to summarize the clinical experience derived from the last 10 years of treatments and prevention using systemic compounds. Results showed that the cytoprotective drug amifostine, and its antioxidant agents, are the most discussed as preventive agents of xerostomia in head and neck cancer (HNC) patients. In the presence of the disease, the pharmacological treatments have been mainly directed to stimulate secretion of the damaged salivary glands, or to counteract a decreased capacity of the antioxidant system, in view of an increasing of reactive oxygen species (ROS). However, the data demonstrated low ability of the drugs, together with a great number of side effects, which strongly limit their use. Concerning traditional medicine (TM), valid clinical trials are so limited that neither the efficacy nor the absence of interferences to concomitant chemical therapies can be validated. Consequently, the management of xerostomia and its devastating complications remain a very significant void in daily clinical practice.

Abstract
OBJECTIVE This study aimed to evaluate the effect of methanol (70% v/v), ethanol (80% v/v), dimethyl sulfoxide (DMSO; 100% v/v) extracts of ginger rhizome (GR), and 6-shogaol on the pilocarpine-stimulated salivary flow rate in C57BL/6 mice. METHODS Three extracts of ginger (Zingiber officinale) rhizome prepared by maceration using the respective solvents and 6-shogoal were reconstituted in normal saline with 0.2% DMSO. Thirty C57BL/6 15-week-old mice were divided into 5 groups: Group 1, saline; Group 2, 70% methanol extract; Group 3, 80% ethanol extract; Group 4, 100% DMSO extract; and Group 5, 6-shogaol. The baseline pilocarpine-stimulated salivary flow rate was measured at the age of 15 weeks (15th week), and treatment solutions were administered by intraperitoneal injection from the 16th to 18th week. The stimulated salivary flow rate during treatment weeks was recorded for each group, and its difference with baseline was analysed using paired-sample t test. The change in salivary flow rate between the treatment groups and the control group was analysed using one-way analysis of variance. RESULTS Groups 2, 3, 4, and 5 showed a significant increase in salivary flow rate when compared to baseline (P < .05). The increase in salivary flow rate in all 4 treatment groups was significant when compared to the control group (P < .05). Group 4 produced the highest increase in salivary flow rate; however, the differences amongst the treatment groups did not reach statistical significance (P > .05). CONCLUSIONS All GR extracts (70% methanol, 80% ethanol, 100% DMSO) and 6-shogaol were equally effective in increasing the pilocarpine-stimulated salivary flow rate in C57BL/6 mice when administered systemically as a sustained dose for 3 weeks.

Abstract
BACKGROUND AND OBJECTIVES Cancer-related fatigue (CRF) is one of the most prevalent complications experienced by cancer patients during and after the process of treatment. Despite conducting a lot of studies, there is no approved therapy to help manage CRF. This study aims to investigate the efficacy of bupropion on CRF. MATERIALS AND METHODS In this double-blind randomized placebo-controlled clinical trial, a total of 30 eligible cancer patients suffering from fatigue were randomly divided into two groups (15 patients in each group). Bupropion was administered 75 mg/day for the first three days and 150 mg/day (divided in two doses) till the end of the study at week 6. Fatigue as the primary outcome was measured by BFI (Brief Fatigue Inventory) and FACIT-Fatigue (Functional Assessment of Chronic Illness Therapy) scales. Secondary outcomes included HADS (Hospital Anxiety and Depression Scale) and performance status (PS) measured by Karnofsky and ECOG (Eastern Cooperative Oncology Group) scales. Assessments were done at baseline, end of the second and sixth week. RESULTS There was no significant difference between placebo and bupropion at baseline and the end of second week. Significant difference was seen between two groups at the end of week six (P = 0.006 based on BFI) in favor of bupropion. In-group assessment showed improvement in fatigue levels in both groups during study time (P = 0.000 based on BFI for both bupropion and placebo). Secondary outcomes (e.g., HADS and PS) were not different at baseline and the end of second week. However, at the end of week six, the difference was significant in favor of bupropion. CONCLUSION A six-week trial of bupropion reduces the CRF and improves the PS of cancer patients. TRIAL REGISTRATION Current Controlled Trials IRCT20090613002027N12, registration date: 2018-06-01.

Abstract
Aims: Xerostomia syndrome is a significant medical and social problem. It is manifested by objective and subjective symptoms of a “dry mouth” and a decrease in sialometry. The aim of the study was to determine the dental status of students of different nationalities, to identify xerostomia induced on a background of stress, and to assess the effectiveness of the use of moisturizing foams in alleviating xerostomia. Materials and Methods: A prospective cohort study survey (Fox test) of 100 students of the dental faculty was conducted to detect false xerostomia. The study involved 60 people with false xerostomia, divided into four groups of 15 each according to the nationality. The level of oral hygiene was determined using the Simplified Oral Hygiene and Silness-Loe indices and the rate of salivation was assessed with sialometry method by Pozharitskaya. Oral hygiene instructions were given to the participants. They were to apply moisturizing foams with lactoferrin, lactoperoxidase, and aloe vera, two–three times during the day for 3 weeks. A set of statistical programs was used (Microsoft Excel [2007] and the Statistical Package for the Social Sciences [SPSS], version 23) to perform Kolmogorov–Smirnov, Shapiro–Wilk, Kruskal–Wallis, and Wilcoxon tests. Results: A statistically significant improvement in oral hygiene was observed in all study participants. A significant increase was detected in the rate of salivation in students from Russia (P = 0.005), Transcaucasian countries (P = 0.006), and Arab countries (P = 0.005). Conclusion: It has been established that the use of moisturizing foam has a positive effect on the rate of salivation and improves the level of oral hygiene, thereby improving the quality of life for patients.

Abstract
PURPOSE More than 80% head and neck cancer patients endured radiotherapy-induced xerostomia which impacts their quality of life (QoL). This observational study evaluated the effect of herbal treatment on head and neck cancer patients' xerostomia and QoL. METHODS Head and neck cancer patients were recruited from July 2016 till March 2017 at National Cancer Institute, Ministry of Health, Malaysia. All study participants continued their standard oncology surveillance. Treatment group participants additionally received Chinese herbal treatment. The assessments included unstimulated salivary flow rate (USFR), stimulated salivary flow rate (SSFR), and QoL questionnaire. RESULTS Of 42 recruited participants, 28 were in the treatment group and 14 were in the control group. Participants were mainly Chinese (71.4%), stage III cancer (40.5%), and had nasopharynx cancer (76.2%). The commonly used single herbs were Wu Mei, San Qi, and Tian Hua Fen. Sha Shen Mai Dong Tang, Liu Wei Di Huang Wan, and Gan Lu Yin were the frequently prescribed herbal formulas. The baseline characteristics, USFR, SSFR, and QoL between control and treatment groups were comparable (p > 0.05). USFR between control and treatment groups were similar throughout the 6-month study period. SSFR for the treatment group significantly improved from 0.15 ± 0.28 ml/min (baseline) to 0.32 ± 0.22 ml/min (p = 0.04; at the 3rd month) and subsequently achieved 0.46 ± 0.23 ml/min (p = 0.001; at the 6th month). The treatment group had better QoL in terms of speech (p = 0.005), eating (p = 0.02), and head and neck pain (p = 0.04) at the 6th month. CONCLUSION Herbal treatment may improve xerostomia and QoL in post-radiotherapy head and cancer patients.
