Papillary thyroid carcinoma (PTC) is the most common thyroid cancer and has a good prognosis.According to the 2015 American thyroid association (ATA) guidelines, no gross extrathyroidal extension and the number of pathological lymph node micrometastases (<0.2cm) ≤5 were defined as the low recurrence risk group. After total thyroidectomy and radioiodine treatment, the probability of disease-free status (irritant Tg<1ng/ml, no evidence of other disease recurrence) is about 78%-91%, and the probability of structural recurrence is about 1%-10%. In recent years, due to the further understanding of PTC, surgeons tend to become more conservative in treatment, such as active observation or reducing the extent of surgery. The indication for lobectomy has been extended to tumors <4cm without extrathyroidal extension and clinical lymph node metastasis. For patients treated with lobectomy, current guidelines recommend that Thyroid Stimulating Hormone (TSH) be controlled at 0.5-2 mU/L, but evidence on the prognostic benefits of this TSH inhibition range is lacking.In recent years, a number of studies have suggested that if postoperative TSH in low-risk patients after lobectomy is acceptable within the reference range, it means that a considerable number of patients have a high probability of not receiving thyroxine replacement therapy after surgery, which can significantly improve their quality of life.A previous retrospective study from our institute showed no significant association between TSH levels after lobectomy and prognosis.The aim of this study was to evaluate the benefits and risks of postoperative TSH levels within the reference range (0.4-5 mU/L) in patients with low-risk papillary thyroid cancer who underwent lobectomy.In order to improve the effect of longer recurrence and death time of PTC, the investigators also performed postoperative thyroglobulin and its antibody for short-term treatment response evaluation.
The treatment efficacy for stage IVb esophageal cancer has been improved through chemotherapy combined with immunotherapy recently. On this basis, the investigators intend to conduct a prospective, multicenter phase III clinical trial to assess whether radiotherapy with concurrent chemotherapy and immunotherapy could further improve the survival of patients with metastatic esophageal cancer. Accompanied tissue samples, blood samples and urine samples will be analyzed by molecular biological detection (Including Whole Exome Sequencing and proteomics) to explore potential biomarkers for predicting outcomes, efficacy and toxicity.
Chemokine receptor CXCR4 was expressed in T cells and CXCR4-targeting molecular imaging- 68Ga-Pentixafor PET/CT could be a promising technique to evaluate the extent of thymoma with higher accuracy. This prospective study is going to investigate whether metabolic characterization by 68Ga-Pentixafor PET/CT may be superior for diagnosis, distinguish evaluation for thymoma.
As the most common subtype of lymphoma, diffuse large B-cell lymphoma (DLBCL) is an aggressive but potentially curable malignancy. However, patients with early relapse (relapse within 12 months since diagnosis or the end of first-line treatment, ER) or primary refractory had an even worse prognosis. Thus, the investigators plan to evaluate the efficacy and safety of anlotinib combined with rituximab, gemcitabine, oxaliplatin (A-RGEMOX) in the treatment of early relapsed/refractory diffuse large B-cell lymphoma.
To investigate the efficacy and safety of new-type mask compared with nasal tube oxygen delivery in patients undergoing sedation of upper gastrointestinal endoscopy
The goal of this clinical trial is to explore the efficacy of VR exposure intervention in alleviating fear of flying through a randomized controlled study.
This is a prospective, randomized, open label, parallel,6-month study to explore and evaluate the therapeutic effects of Henagliflozin on the cognitive function, olfactory function, and odor-induced brain activation in T2DM patients with mild cognitive impairment (MCI).
The goal of this type of study is to construct the continuous quality promotion project "ICU-NO CRBSI(Catheter-Related Bloodstream Infection , CRBSI)" based on improvement science, and to verify its effect in the prevention of central venous catheter-related bloodstream infection and continuous quality improvement in ICU ( Intensive Care Unit , ICU) through multi-center implementation and two rounds of improvement. The main question[s] it aims to answer are: What is the incidence of catheter-related bloodstream infection in the ICU of participating units? How compliant are health care providers in the ICU with evidence-based sensory control practices for the prevention of catheter-associated bloodstream infection? Participants will be provided with the hospital's routine CVC (Central Venous Catheter ,CVC) care practices and CVC quality improvement measures based on evidence-based guidelines What technical and cultural support is needed to implement quality and safety improvement measures?
Adolescent idiopathic scoliosis (AIS) is the most common three-dimensional deformity of the spine that is typically characterized by curvature in both the coronal and sagittal planes. Selective thoracolumbar fusion (STLF) surgery, is an established corrective surgical technique for spinal deformities with excellent outcomes over time1. The objective of AIS corrective surgery encompasses the rectification of coronal and spinal rotation deformities while concurrently restoring the sagittal profile. However, some scholars suggested that correcting the Cobb angle and rotation deformity of the main thoracic curve has been associated with a sacrifice of sagittal plane aligament. Some researchers observed that significant reduction of thoracic kyphosis (TK) after the coronal deformity was corrected in their study3-5. In addition, Li et al3 found that both lumbar lordosis(LL) and sacral slope (SS) decreased after STLF surgery in their study. The sagittal plane of the spine column should be considered a chain-like structure, one section's change, that leads to compensatory changes in other segments, enables the maintenance of balance6. In addition, some scoloars suggested that the decrease in thoracic kyphosis may caused by vertebral derotation in STLF surgery. Postoperative shoulder imbalance (PSI) is a common complication that arises following STLF surgery, significantly impacting the appearance and satisfaction of patients8. The incidence of PSI varies within a range of 25% to 57%. It is imperative to identify the independent risk factors of PSI which can help in comprehending this phenomenon better and further aiding in deduction of the incidence rate. Although the research on the risk factors for PSI in AIS patients have been conducted for several years , no conclusively determination has been reached. Recently, scholars have been studying the relationship between the rotation of the thoracic spinal column and postoperative shoulder balance. Yagi et al.'s study10 has identified the preoperative rotation of the main thoracic apical vertebrae as a risk factor for PSI. Additionally, Masayoshi et al has reported on the relationship between the rotation of the proximal thoracic apical vertebrae and postoperative shoulder height disatance. In summary, it can be hypothesized that the preoperative and changes of postoperative sagittal spinal parameters may impact the postoperative shoulder balance among AIS patients. However, there is a paucity of literature investigating the effect of sagittal spinal parameters on PSI after STLF surgery. Therefore, the purpose of this study is to examine the correlation between the preoperative and postoperative alterations of sagittal spinal parameters and PSI.
This study will conduct a prospective single blind controlled study on the clinical efficacy and safety indicators of 50 cancer patients with acute lower limb deep vein thrombosis (DVT). The patients were randomly divided into an experimental group (improved mechanical thrombectomy (PMT) group) and a control group (traditional simple anticoagulation group) using the "envelope method", with 25 cases each. After the end of treatment, clinical prognosis evaluations were conducted on the patient's vital signs, symptoms and signs, lower limb Doppler ultrasound examination, patient PTS score (Villalta score), quality of life score (QOL), etc. at 3, 6, and 12 months. Adverse events, the presence or absence of thrombus recurrence, and re surgical intervention were recorded. This study is expected to propose a new strategy for the treatment of acute DVT in cancer patients, thereby improving the overall level of VTE prevention and treatment.
