[PMID: 33827606 PMCID: PMC8028710 DOI: 10.1186/s12967-021-02809-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 03/26/2021] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Glioma is a complex cancer with a high morbidity and high mortality. Bone marrow mesenchymal stem cells (BMSCs) have shown promise as an excellent cell/drug delivery vehicle for gene-targeted therapy; however, maintaining genetic stability and biological activity remains difficult. Furthermore, whether BMSCs support or inhibit tumor growth remains debated. This study investigated whether a traditional Chinese medicine fomular, Fuzheng Yiliu decoction (FYD) had a synergistic antitumor effect with IL-12 gene-modified BMSCs in glioma-bearing nude mice METHODS: The lentivirus-mediated IL-12 gene was transfected into primarily cultured BMSCs. A total of 72 BALB/c nude mice were used to establish xenograft models with glioma U251 cells and were divided into groups (n = 12) including blank control group, nude mouse model group (model group), lentiviral transfection of BMSC group with no gene loading (BMSC group), IL-12 lentivirus-transfected BMSC group (IL-12 + BMSC group), FYD treatment group (FYD group), and FYD treatment in IL-12 lentivirus-transfected BMSC group (FYD + IL-12 + BMSC group).. After treatment for 14 days, all mice were sacrificed to collect tumor tissue and serum for more detection, such as distribution of BMSCs, cell apoptosis in xenograft tumors, serum IL-12 and INF-γ levels, mouse weight and tumor volume were measured RESULTS: There were significantly more apoptotic cells in tumor tissue in IL-12 gene transfected group, FYD treatment group and FYD combining with IL-12 gene transfected group than that in the model group (P < 0.05). The FYD + IL-12 + BMSC group showed significantly higher Bax and lower Bcl-2 expression (P < 0.05), and serum IL-12 and INF-γ levels (P < 0.05) were higher than that in all other groups. After the intervention, this group also showed a strong inhibitory effect against tumor growth (P < 0.05) CONCLUSIONS: This study suggested FYD treatment combined with IL-12 gene-modified BMSCs shows synergistic antitumor effect in glioma-bearing nude mice.

Traditional Herbal Medicine Mediated Regulations during Head and Neck Carcinogenesis. Biomolecules 2020; 10:biom10091321. [PMID: 32942674 PMCID: PMC7565208 DOI: 10.3390/biom10091321] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Revised: 09/13/2020] [Accepted: 09/14/2020] [Indexed: 01/31/2023] Open
Abstract
Head and neck squamous cell carcinoma (HNSCC) is one of the most prevalent neoplasms worldwide. It is well recognized that environmental challenges such as smoking, viral infection and alcohol consumption are key factors underlying HNSCC pathogenesis. Other than major clinical interventions (e.g., surgical resection, chemical and radiotherapy) that have been routinely practiced over years, adjuvant anticancer agents from Traditional Herbal Medicine (THM) are proposed, either alone or together with conventional therapies, to be experimentally effective for improving treatment efficacy in different cancers including HNSCCs. At a cellular and molecular basis, THM extracts could modulate different malignant indices via distinct signaling pathways and provide better control in HNSCC malignancy and its clinical complications such as radiotherapy-induced xerostomia/oral mucositis. In this article, we aim to systemically review the impacts of THM in regulating HNSCC tumorous identities and its potential perspective for clinical use.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 664:690-697. [PMID: 30763849 DOI: 10.1016/j.scitotenv.2019.02.040] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/13/2018] [Revised: 12/02/2018] [Accepted: 02/02/2019] [Indexed: 02/08/2023]
Abstract
Lead (Pb) toxicity damages blood cells and disturbs the immune micro-environment. When Pb enters the circulatory system, >95% of Pb accumulates in erythrocytes. We therefore conducted this study to explore the long-term effect of Pb exposure on expression of erythrocyte adhesion molecules (CD44 and CD58) and related downstream cytokine concentrations. We enrolled a total of 267 preschool children, 2-7 years of age, from Guiyu (e-waste-exposed group, n = 132) and Haojiang (reference group, n = 135) in November and December 2015. We measured child blood Pb, biomarkers including erythrocyte CD44 and CD58, erythrocyte count, leukocyte count and inflammatory cytokines (IL-1β, IL-12p70 and IFN-γ), and calculated erythrocyte Pb levels. Regression model demonstrated that higher erythrocyte Pb was associated with lower CD44 and CD58. Compared to low erythrocyte Pb levels (quartile 1), high erythrocyte Pb levels (quartile 4) were related to lower levels of erythrocyte CD44 and CD58. Elevated blood Pb correlated with higher IL-12p70 and IFN-γ, and lower IL-2. The mediation effect of erythrocyte CD44 on the relationship of erythrocyte Pb with IL-1β and IL-12p70 was significant, and the effect of erythrocyte Pb on IFN-γ was mediated by erythrocyte CD58. The data provides novel translational insight into the relationship between elevated Pb exposure and the change of erythrocyte immunity and downstream cytokine secretion in preschool children.

Abstract
The present study aimed to explore the effects of different anesthetic methods on cellular immune function and prognosis of patients with ovarian cancer (OC) undergoing oophorectomy. A total of 167 patients who received general anesthesia (GA) treatment (GA group) and 154 patients who received combined general/epidural anesthesia (GEA) treatment (GEA group) were collected retrospectively. Each group selected 124 patients that met the inclusion and exclusion criteria for further study. ELISA and radioimmunoassay were employed to detect levels of IL-2, TNF-α, and CA-125. The rates of tumor-red cell rosette (RTRR), red cell immune complex rosette (RRICR), and red cell C3b receptor rosette (RRCR) were also measured. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were determined by hemodynamics. The levels of tumor necrosis factor-α (TNF-α) and interleukin (IL)-2 decreased at 1 h intraoperation (T2), but increased 24-h post surgery (T3). The levels of TNF-α and IL-2 were recovered faster in the GEA group than in the GA group. The GA group exhibited greater levels of CA-125 expression than in the GEA group. The levels of RTRR, RRICR, and RRCR; ratios of CD3+, CD4+, CD4+/CD8+, CD16+, and CD56+ at 30 min after anesthesia (T1), T2, T3 and 48 h after the operation (T4) and levels of SBP, DBP, and HR at T1, T2, and T3 displayed increased levels in the GEA group than in the GA group. At 72-h post surgery (T5), the 5-year survival rate significantly increased in the GEA group compared with the GA group. GEA to be more suitable than GA for surgery on OC patients.

Abstract
BACKGROUND To investigate the effects of double radiofrequency hyperthermia on Th1/Th2 cells in esophageal cancer patients treated with radiotherapy. MATERIALS AND METHODS 22 patients with esophageal cancer were divided into a radiotherapy group (10 cases) and a combined group (double radiofrequency hyperthermia combined with radiotherapy group, 12 cases). Both groups received conventional radiotherapy using a cobalt-60 therapy apparatus (TD60-66Gy/30-33F). Patients in the combined group also underwent double radiofrequency hyperthermia (2F/W, 8-10F). Before and after treatment, Th1, Th2, Tc1 and Tc2 cells in peripheral blood were determined with flow cytometry. RESULTS In the radiotherapy group, Th1 cell contents before and after radiotherapy were 17.5 ± 5.26% and 9.69 ± 4.86%, respectively, with a significant difference (p<0.01). The Th1/Th2 ratio was significantly decreased from 28.2 ± 14.3 to 16.5 ± 10.4 (p<0.01). In the combined group, Th1 cell content before radiotherapy was 15.9 ± 8.18%, and it increased to 18.6 ± 8.84 after radiotherapy (p>0.05), the Th1/Th2 ratio decreasing from 38.4 ± 36.3 to 28.1 ± 24.0 (p>0.05). Changes in Th2, Tc1 and Tc2 cell levels were not significant in the two groups before and after therapy (p>0.05). CONCLUSIONS Double radiofrequency hyperthermia can promote the conversion from Th2 to Th1 cells, and regulate the balance of Th1/Th2 cells.

JOURNAL OF ETHNOPHARMACOLOGY 2010; 127:760-7. [PMID: 19961915 DOI: 10.1016/j.jep.2009.11.024] [Citation(s) in RCA: 125] [Impact Index Per Article: 8.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/21/2009] [Revised: 11/17/2009] [Accepted: 11/24/2009] [Indexed: 05/20/2023]
Abstract
AIM OF THE STUDY Various parts of Carica papaya Linn. (CP) have been traditionally used as ethnomedicine for a number of disorders, including cancer. There have been anecdotes of patients with advanced cancers achieving remission following consumption of tea extract made from CP leaves. However, the precise cellular mechanism of action of CP tea extracts remains unclear. The aim of the present study is to examine the effect of aqueous-extracted CP leaf fraction on the growth of various tumor cell lines and on the anti-tumor effect of human lymphocytes. In addition, we attempted to identify the functional molecular weight fraction in the CP leaf extract. MATERIALS AND METHODS The effect of CP extract on the proliferative responses of tumor cell lines and human peripheral blood mononuclear cells (PBMC), and cytotoxic activities of PBMC were assessed by [(3)H]-thymidine incorporation. Flow cytometric analysis and measurement of caspase-3/7 activities were performed to confirm the induction of apoptosis on tumor cells. Cytokine productions by PBMC were measured by ELISA. Gene profiling of the effect of CP extract treatment was performed by microarray analysis and real-time RT-PCR. RESULTS We observed significant growth inhibitory activity of the CP extract on tumor cell lines. In PBMC, the production of IL-2 and IL-4 was reduced following the addition of CP extract, whereas that of IL-12p40, IL-12p70, IFN-gamma and TNF-alpha was enhanced without growth inhibition. In addition, cytotoxicity of activated PBMC against K562 was enhanced by the addition of CP extract. Moreover, microarray analyses showed that the expression of 23 immunomodulatory genes, classified by gene ontology analysis, was enhanced by the addition of CP extract. In this regard, CCL2, CCL7, CCL8 and SERPINB2 were representative of these upregulated genes, and thus may serve as index markers of the immunomodulatory effects of CP extract. Finally, we identified the active components of CP extract, which inhibits tumor cell growth and stimulates anti-tumor effects, to be the fraction with M.W. less than 1000. CONCLUSION Since Carica papaya leaf extract can mediate a Th1 type shift in human immune system, our results suggest that the CP leaf extract may potentially provide the means for the treatment and prevention of selected human diseases such as cancer, various allergic disorders, and may also serve as immunoadjuvant for vaccine therapy.

Abstract
Traditional Chinese medicines are sometimes used as an adjunct to radiotherapy or chemotherapy for esophageal cancer. These medicines may have a benefit on the survival and quality of life of patients who have advanced esophageal cancer. Evidence from current studies appears weak due to methodological limitations. Due to conflicting reports, it is difficult to argue for or against the use of traditional Chinese medicines as a treatment for esophageal cancer.
