RESUMEN
Objective To investigate the correlation between ADC value and glioma IDH-1/1p19q genotype. Methods The MRI features and molecular pathological results of 69 patients with pathologically confirmed diagnosis of WHO grade Ⅱ/Ⅲ glioma between March 2013 and December 2020 were retrospectively analyzed. The diagnostic performance of ADC values on glioma genotypes (IDH-1, 1p19q) was evaluated using the ROC curve of the subjects' working characteristics. Results The ADCmean, ADCmin, rADCmean, and rADCmin in the IDH-1 mutation group were significantly higher than those in the IDH-1 wild group (P < 0.05, P < 0.01, P < 0.05, P < 0.01). The use of the rADCmin threshold (0.979×103mm2/s) had the highest efficacy (AUC=0.770) for diagnosis of IDH-1 mutant and IDH-1 wild-type gliomas as well as sensitivity and specificity of 84.61% and 59.09%, respectively. Conclusion ADC can be used as an imaging biomarker for noninvasive prediction of IDH-1 mutant and wild-type Ⅱ /Ⅲ gliomas.
RESUMEN
Lymphocyte subsets and tumor-associated macrophages, which are the primary immune cells in the tumor microenvironment, interacts with its released cytokines to form the immunological microenvironment. It has grown to be a significant factor in the recurrence and metastasis of cervical cancer and influences the effectiveness of concurrent radiotherapy and chemotherapy for the disease, which in turn influences the prognosis and outcome of patients. Immunotherapy and targeted therapy for cervical cancer based on the immune microenvironment have grown in popularity as research topics in recent years.
RESUMEN
The occurrence and progression of cervical cancer are influenced by gut flora. Patients with cervical cancer have different gut flora from healthy women, and the detection and evaluation of gut flora can help in the diagnosis, immunotherapy, assessment of radiotherapy efficacy and prognosis prediction of cervical cancer. Regulation of gut flora is of great clinical value in enhancing response to anti-tumor therapy, improving patients' quality of life and improving prognosis.
RESUMEN
Immune checkpoint inhibitors in the treatment of head and neck squamous cell carcinoma (HNSCC) has shown significant clinical benefit. Some studies have shown that radiotherapy combined with immunotherapy can produce synergistic effects, and several phase Ⅰ/Ⅱ clinical trials have suggested that radiotherapy combined with immunotherapy has good safety and preliminary efficacy benefits in locally advanced HNSCC. However, the timing of combination therapy, the selection of radiotherapy dose/fractionation mode and patients are still unclear. This article further discusses the synergistic mechanism, clinical research status and challenges of radiotherapy combined with immunotherapy in the treatment of HNSCC, aiming to guide the clinical practice and improve the prognosis of HNSCC patients.
RESUMEN
Gliomas,as the most common central nervous system tumors,still have a poor prognosis for patients after compre-hensive treatment with surgery,radiotherapy,and chemotherapy.The occurrence,development,invasion and treatment resistance of tumors are closely related to the immune infiltrating cells in the tumor microenvironment.Macrophages/microglia are the main immune-infiltrating cells in the microenvironment of gliomas,and significant progress has been made in their research in recent years,provi-ding new ideas for the treatment of gliomas.This article reviews the research progress of macrophages/microglia in the microenviron-ment of glioma.
RESUMEN
Quantifying the allocation of photosynthetic products among different carbon (C) pools is critical for understanding and predicting plant C turnover response to climate change. A field experiment with ectomycorrhizal fungi (EMF) and nitrogen (N) was established to investigate the effects on allocation of photosynthetic products in Pinus massoniana (Lamb.) seedlings given increased N deposition. Seedlings were subjected to N addition and symbiosis with EMF, and the short-term allocation of a 13C photosynthetic pulse into leaves, branches, stems, roots, and soil was traced. Photosynthetic rate and root respiration were measured. It was found that N addition changed the allocation pattern of photosynthetic products in various organs of P. massoniana. Furthermore, N addition, mycorrhizal symbiosis, and interaction of N and EMF, all increased the amount of C produced by photosynthesis. N application less than 60 kg N hm-1 a-1 could promote the transfer and allocation of photosynthetic products in P. massoniana organs, which peaks at 60 kg N hm-1 a-1, and the highest N treatment began to decrease at 90 kg N hm-1 a-1. EMF inoculation could expand the absorption area of plant roots to obtain more nutrients and synthesize more C and N compounds for promoting the growth of itself and the host plant, improving the net photosynthetic rate and the distribution of C produced by photosynthesis in various organs. This forms a benign C and N cycle, thereby reducing the effect of high N addition on plants. The optimal N addition concentration was 60 kg N hm-1 a-1, and the optimal EMF was Pt, which provides a theoretical basis for inoculating EMF during increasing N deposition in the future climate change scenario. This enables plants to distribute more photosynthetic products to their roots, thus affecting their own C distribution for promoting growth.
RESUMEN
Following oxidative stress, reactive oxygen species are produced and accumulate in glioma cells in large quantities, and to avoid the occurrence of cellular dysfunction, glioma cells can respond adaptively in the biological processes of DNA damage repair, lipid peroxidation and protein modification to produce radiotherapy resistance. The expression of nuclear factor erythroid 2-related factor 2, solute carrier family 7 member 11, glutathione and microRNA, as key regulatory molecules, can regulate reactive oxygen species levels, alter glioma oxidative stress status, and affect radiochemotherapy sensitivity. Further study on the relationship between oxidative stress and sensitivity to radiotherapy and chemotherapy of glioma can provide theoretical basis for precise treatment of glioma.
RESUMEN
Glioma is the most common primary brain tumor in adults and is essentially a polygenic abnormal disease. Solute carrier family 7 member 11 (SLC7A11) is a core component of the cystine/glutamate transporter and its expression is regulated at the transcriptional and translational levels. SLC7A11 mediates glioma cells proliferation, invasion and chemoradiotherapy resistance through regulation of oxidative stress and ferroptosis. Deep study of SLC7A11 will provide new theoretical basis and therapeutic targets for the treatment of gliomas.
RESUMEN
Objective:In China, although axillary osmidrosis is common in plastic surgery, there is no standard procedure for the treatment of axillary osmidrosis. So we compared the efficacy of 6 axillary osmidrosis surgical treatments with network meta-analysis in order to provide reference for the clinical surgical treatment of axillary osmidrosis in Chinese patients.Methods:From January 2018 to December 2021, Chinese and English databases including Wanfang Database, VIP Chinese Science and Technology Periodical Full-text Database (VIP) and CNKI, PubMed, Cochrane Library, Embase were searched by the Plastic Surgery Department of Zhangqiu People′s Hospital in Jinan, Shandong province. And some relevant studies were collected for network meta-analysis.Results:47 studies including a total of 6543 subjects were identified for meta-analysis. After analysis, 4 of the 15 pairwise comparisons were not statistically significant, and the effect of swelling aspiration + subcutaneous pruning was more significant. According to the surface under the cumulative ranking curve (SUCRA), the efficacy of 6 surgical methods for the treatment of axillary osmidrosis was as follows: swelling aspiration + subcutaneous pruning > subcutaneous scratching+ subcutaneous pruning > subcutaneous pruning > fusiform skin resection > subcutaneous scratching > swelling aspiration.Conclusions:In surgical treatment of axillary osmidrosis, swelling aspiration + subcutaneous pruning is the best. It is worth popularizing in the clinical work of treating axillary osmidrosis patients. Due to the limitations of this study, the conclusion of this network meta-analysis still needs to be further confirmed by a well-designed randomized controlled trial.
RESUMEN
Radiotherapy is an important auxiliary treatment for glioma. Although comprehensive treatment of glioma has made some progress in recent years, the prognosis is still poor. How to improve the radiosensitivity of glioma is one of the hot spots in current glioma research. The changes of energy metabolism in gliomas promote malignant progression and resistance to chemoradiotherapy, but the exact mechanism is still unclear. This paper reviews the research progress of energy metabolism in gliomas and its relation with radiosensitivity of gliomas, in order to lay a foundation for further exploration of improving radiosensitivity of gliomas.
