Filter by:This study aims to identify the prognostic role of procalcitonin (PCT), soluble Triggering Receptor Expressed on Myeloid Cells-1 (sTREM-1), the soluble form of the urokinase plasminogen activator receptor (suPAR), highly sensitive C-reactive protein (hs-CRP), Interleukin-6 (IL-6), and azurocidin 1 (AZU1) in 28-day mortality for patients with sepsis in Emergency Department.
Head and neck squamous cell carcinoma (SCC) is the sixth most common cancer worldwide, with more than 700,000 new cases and more than 350,000 deaths each year. At present, radiotherapy is an important measure to control the recurrence of head and neck tumors, but almost all patients with head and neck squamous cell carcinoma will have acute inflammatory reactions such as radiotherapy-induced oral mucositis (RIOM) after radiotherapy, which seriously affects the quality of life and radiotherapy efficacy of patients. Serum amyloid A1 (SAA1) is an acute phase protein associated with inflammation. Our previous basic research found that serum SAA1 expression levels can be used as biomarkers to assess the dose received by the receptor in the early stages of radiation damage. At the same time, we confirmed that the serum level of SAA1 in patients with nasopharyngeal carcinoma increased after radiotherapy. Therefore, we intend to conduct a prospective, multicenter, observational study to further explore the predictive power of plasma SAA1 levels for radiotherapy-induced oral mucositis, with a view to early screening and prevention of RIOM patients.
Immune checkpoint inhibitors have ushered in a new era of cancer treatment, bringing significant survival benefits to patients. However, some patients have accelerated tumor growth in the early stage of immunotherapy, called hyperprogression. The quality of life of patients with hyperprogression is seriously reduced, and there is no effective treatment at present, and the prognosis is extremely poor. Therefore, early identification of high-risk groups of hyperprogression is the key to prevent hyperprogression. However, there are no effective biomarkers to predict hyperprogression. By sequencing, proteomics and metabolomics analysis of clinical tissue and blood samples, we found that the level of SAA1 was significantly increased in patients with hyperprogression, and SAA1 was an effective marker for predicting hyperprogression in pan-cancer. We planned to conduct a multicenter, prospective cohort study to verify the reliability of SAA1 as a marker for predicting hyperprogression of immunotherapy in pan-cancer patients.
Prospective, multicenter, noninterventional, nonprofit study of a cohort of patients with glioma, aimed at validating miRNA-serum signatures associated with IDH1 status and prognosis, as reliable, specific and sensitive circulating diagnostic biomarkers also useful for improve prognostic stratification of patients. The study will be conducted on serum samples at diagnosis, at 4-6 days postoperatively and/or at the first post-surgery follow-up, in a new cohort of glioma patients and representative of different IDH1 mutational statuses. Furthermore, because comparison of miRNA expression profiles in serum and tissue may provide further evidence to support the use of serum miRNAs as reliable biomarkers reliable, their expression will also be analyzed, where possible, in tissue biopsies from the same patient and compared with the expression profiles of serum miRNAs.
Radiotherapy is one of the main treatments for malignant tumors, and according to authoritative estimates, about 70% of patients with malignant tumors should receive radiotherapy. However, radiation resistance limits its application and clinical curative effect. To find suitable radiation resistance markers and identify patients with radiation resistance, early part of the patients with appropriate radiotherapy sensitization agent or choose other more efficient and low toxicity of treatment, for improving the prognosis of patients, improve the quality of survival is of great significance, it is also the difficult point in the present study. However, there are no effective biomarkers to predict radiosensitivity. Through our previous basic research and analysis of clinical tumor tissues, we have found that the low expression of copper metabolism domain protein 10 (COMMD10) is associated with radioresistance, and COMMD10 is an effective marker for predicting radiosensitivity. We planned to conduct a single-center, prospective cohort study to verify the reliability of COMMD10 as a predictive marker for radiosensitivity in pan-cancer patients.
The goal of this observational study is to find differences in serum biomarkers between ovarian function and normal individuals.
Acute heart failure (AHF) is defined as new or worsening of symptoms and signs of heart failure and is the most frequent cause of unplanned hospital admission in elderly patients. N-terminal pro-brain natriuretic peptide (NT-pro-BNP) is one of the most developed prognostic markers for AHR patients and. NT-pro-BNP has limitations in terms of diagnostic or predictive accuracy in patients with chronic kidney disease (CKD). Plasma proteomics have the potential to examine underlying pathophysiological and prognostic roles, so we compared the plasma proteomic signature to predict outcomes of patients with or without CKD hospitalized for AHF.
Increasing data has indicated an association between increased soluble B7-H3 (sB7-H3) levels and unfavorable prognosis in patients with malignancies. However, the level of sB7-H3 and its clinical significance in osteosarcoma are not well known. In this present study, we investigated whether sB7-H3 levels in serum could be as a biomarker for osteosarcoma treatment.
Individual differences in drug efficacy and adverse reactions are common in the clinical application of drugs. Individual differences are caused by many factors, among which genetic factors account for more than 20%. Novel oral anticoagulant drugs (NOACs, including rivaroxaban, apixaban, edoxaban, dabigatran, etc.) and novel antiplatelet drug ticagrelor have the advantages of convenient use and no need for monitoring. But novel oral antithrombotic drugs also increase the risk of bleeding, and there is currently a lack of effective antagonists when antithrombosis is excessive or emergency surgery is required. At present, there are few studies on the causes of individual differences in novel antithrombotic drugs, and there is a lack of predictable biomarkers or drug genotypes, especially in China. Therefore, on the basis of previous studies on NOACs and ticagrelor individualized medication cohorts, this study plans to establish a validation cohort for novel antithrombotic drugs bleeding related biomarkers, conduct multi-omics testing and long-term follow-up, and explore markers related to pharmacodynamics of antithrombotic drugs, adverse bleeding reactions and clinical outcomes.
The investigators will first use our previously collected serum samples and surgical/biopsied tissues from HBV-related HCC patients undergoing radiotherapy. The consistency of junctional clones by Capture NGS needs to be tested between both pre- and post-RT serums, and serial changes in copy numbers of vh-DNA by ddPCR are quantified in the representative cases. The same junction clones from pre-post-RT serums and surgical tissues will be confirmed and the copy number changes of vh-DNA be correlated with RT response and disease-control status. The investigators plan to identify HBV integrations by Capture NGS and quantify the specific vh-DNA by ddPCR as personalized biomarkers from the same-patient serum samples. The investigators will further correlate clinical response and recurrence/metastasis with serial changes of vh-DNA copy numbers. The investigators have been prospectively collecting plasma samples from HBV-related HCC patients before/after RT, at 1, 4, 7 months, and at recurrence/metastasis. The investigators plan to confirm the viable role of pre-/post-RT changes of plasma vh-DNA copies of the same junction clone in post-RT response and prognosis. Moreover, The investigators will explore the recurrent/metastatic tumors arising from the original or a de novo one by identifying their clonality with HBV integration patterns. The true value of this novel HBV chimera vh-DNA will be revealed. The results will also support the consolidative use of personalized vh-DNA for earlier evaluating treatment response after RT, for post-RT disease monitoring, and for differentiating clonality at recurrence to design future clinical trial on combinational treatment.
