Trial purpose: To evaluate the safety and effectiveness of using a new remote rehabilitation platform for postoperative rehabilitation in patients with anterior cruciate ligament rupture compared to conventional rehabilitation care through a randomized controlled trial. Test subjects: This study is a multicenter study that recruited 252 participants from three centers (aged ≥ 18 years) for cruciate ligament rupture reconstruction; Exclude patients who have undergone revision and bilateral surgery, and exclude patients with collateral ligament and posterior cruciate ligament injuries in the knee joint. Trial plan: The subjects were randomly enrolled and randomly divided into two groups: the remote rehabilitation group and the traditional rehabilitation group, using a mixed block randomization method. The probability of being divided into both groups was 50%. All subjects received routine outpatient diagnosis and treatment, with the same content. The remote rehabilitation group uses software and sensors to provide remote postoperative rehabilitation guidance. The traditional rehabilitation group receives routine rehabilitation diagnosis and treatment, with face-to-face rehabilitation twice a week. All subjects are required to undergo regular follow-up (1 day before surgery, 3 months after surgery, 6 months). Outcome measures: The main outcome measures were knee isokinetic muscle strength and Lysholm knee joint score . the secondary outcome measures were Y-balance test, Tegner activity scale, health survey summary table (SF-36),The other outcome measures were Anterior Cruciate Ligament Return to Sport After Injury (ACL-RSI) Scale, vas pain score.

Glioblastoma (GBM) is the primary intracranial malignant tumor with the highest morbidity and mortality, and the 5-year survival rate is less than 10%. The number of primary diagnostic patients and deaths of GBM in China ranks first in the world every year, which seriously threatens people's life and health. At present, the clinical treatment strategy of maximum surgical resection combined with concurrent chemo- and radio-therapy and TTF treatment is still not satisfactory, and the median survival time of GBM patients is only 14.4 months. Statins inhibit cholesterol production with few side effects and are widely used for cholesterol control in patients with hyperlipidemia. In recent years, statins have shown good anti-tumor effect. Our previous study found that statins can block the malignant progression of glioma mediated by EGFR pathway. Therefore, the investigators report a clinical study protocol designed to evaluate the clinical efficacy of a comprehensive treatment strategy of atorvastatin (ATO) combined with temozolomide (TMZ) in primary and recurrent glioblastomas with high EGFR expression. The investigators designed a multicenter, single-arm, double-blind, phase II clinical trial to evaluate the efficacy and safety of oral ATO combined with TMZ in EGFR-high expressing GBM. After informed consent was signed by the patient or authorized family members, the patients were treated with the current STUPP regimen and ATO (20mg, qn) orally. The patients were regularly followed up for 52 weeks after treatment. The primary endpoint was progression-free survival (PFS), which was defined as the time from the start of GBM surgery to tumor progression (recurrence) or death. The secondary end point was the rate of tumor control, which was defined as the proportion of patients with a complete response, a partial response, or a stable disease that had shrunk or remained stable for a given period of time. Safety will be assessed during the study by monitoring of regular MRI scans, laboratory tests (liver function, lipid profile, blood routine), electrocardiography, vital signs (blood pressure, pulse, temperature), and weight. The results of this clinical trial will provide key information on whether the oral combination of atorvastatin and temozolomide prolongs PFS in EGFR-high GBM patients with efficacy and safety.
Gastric cancer is the fifth most common cancer worldwide and the third leading cause of cancer-related deaths. Although surgical treatment can benefit the survival of the vast majority of patients, currently only early gastric cancer patients can be cured directly through endoscopic resection or surgery alone. Neoadjuvant therapy reduces tumor volume and improves tumor response rate through preoperative radiotherapy and chemotherapy, thereby increasing R0 resection rate and improving overall survival, without increasing postoperative complications and mortality. Timely imaging re staging during neoadjuvant therapy can allow patients to enter the surgical stage earlier, thereby reducing their preoperative burden. According to the different stages of neoadjuvant therapy, clinical staging can be divided into baseline stage (cBSstage) and clinical rest stage (cReStage) after neoadjuvant therapy. At present, the conventional imaging methods for diagnosing cBStage in gastric cancer include CT, endoscopic ultrasonography (EUS), and MRI. The NCCN guidelines recommend CT for cBStage, with a diagnostic accuracy of 77.1% to 88.9%. Similarly, EUS and MRI were also used for cBStage, with accuracy rates of 65.0% to 92.1% and 71.4% to 82.6%, respectively. The application of diffusion-weighted imaging (DWI) has improved the accuracy of MRI diagnosis of cBStage to 93%. However, due to the destruction of the gastric wall structure by neoadjuvant therapy, accurate imaging re staging is difficult. Currently, accurate tumor regression grading can only be obtained through surgical resection of pathological specimens. For cReT after neoadjuvant therapy, the diagnostic accuracy of EUS is only 63% (T2: 44%, T3: 68%, T4: 90%). Due to the presence of chronic inflammatory reactions, such as tumor cell apoptosis, necrosis, fibrosis, etc., in both the tumor and the critical normal gastric wall after neoadjuvant therapy, imaging cannot accurately identify the level of gastric wall, leading to the current low value of CT for cReT. Meanwhile, due to the fact that the pathological reactions of lymph nodes after neoadjuvant therapy are mainly subacute inflammatory reactions accompanied by scar tissue formation, and not all lymph node volumes that experience these pathological reactions will rapidly decrease, the accuracy of CT diagnosis of cReN is only 44%, while the sensitivity and specificity of EUS diagnosis of cReN are 50% and 56%, respectively. In addition, positron emission tomography (PET) can reflect the abnormal metabolism, protein synthesis, DNA repair, and cell proliferation of tumors at the molecular level, providing important information in tumor grading diagnosis, prognosis evaluation, treatment decision-making, and efficacy monitoring. The conventional positron tracer 18F-FDG can reflect the glucose metabolism ability of different tissues, while most types of malignant tumors exhibit high metabolism. Therefore, 18F-FDG can be used for the diagnosis, staging, and treatment monitoring of cancer. However, in gastric cancer patients, 18F-FDG has certain limitations, including 1) interference with physiological or inflammatory uptake of the gastric wall; 2) Low uptake of 18F-FDG is present in signet ring cell carcinoma, mucinous adenocarcinoma, or other poorly differentiated cancers with high mucus content; 3) There are cases of false positive FDG after immunotherapy. In the study of SUV changes in the tumor area before and after treatment, it was found that patients with postoperative pathological regression grades 1-5 Δ SUVs are between 0-70%. Tumor associated fibroblasts are closely related to tumor growth, invasion, and distant metastasis, and their activation requires the involvement of fibroblast activation protein (FAP). Therefore, radiolabeled fibroblast activation protein inhibitor (FAPI) can achieve in vivo FAP targeted tracing and quantification by specifically binding to FAP. Currently, a large number of studies have shown that 18F-FAPI is superior to 18F-FDG in the staging and re staging of gastric cancer. Furthermore, prospective studies have shown a certain relationship between tumor regression grade (TRG) and 18F-FAPI rate of change parameters (SUVmax, SUVavg, SUVR). Therefore, in the early stage of this study, 18F-FAPI combined with 18F-FDG PET/MRI imaging was used to evaluate the efficacy of neoadjuvant therapy for gastric cancer, preoperative assessment of tumor regression grade after treatment, and re staging to guide the development of further clinical treatment plans.
Acute pancreatitis (AP) is one of the most common diseases of the digestive system, with its incidence increasing year by year. 15%-25% of patients will develop severe acute pancreatitis (SAP), characterized by necrosis and infection of the pancreas and surrounding tissues, as the investigators as multiple organ dysfunction syndrome (MODS), with a mortality rate as high as 17%. Currently, there is a lack of effective measures in clinical practice to regulate the early inflammation and immune response in acute pancreatitis. Animal experimental studies have confirmed that TEA, by blocking the abdominal sympathetic nerves, increases arterial blood flow and venous capacity, improves pancreatic perfusion insufficiency caused by AP, and alleviates metabolic acidosis. Simultaneously, TEA can suppress the secretion of catecholamines during the stress state of acute pancreatitis, reducing the release of inflammatory mediators and thereby inhibiting the inflammatory response. Our team's earlier animal experiments have further confirmed that TEA improves intestinal inflammation in mice with pancreatitis. This improvement is marked by a significant reduction in the concentrations of inflammatory cytokines such as IL-1β and TNF-α. Additionally, there is an observed alteration in the intestinal microbiota, characterized by an increase in the proportion of beneficial bacteria. Based on these findings, it is speculated that TEA, by reducing catecholamine release and downregulating sympathetic activity, effectively mitigates inflammation and stress responses in patients with pancreatitis. Furthermore, TEA dilates small arteries in blocked segments, thereby improving blood flow and microcirculation within the affected area. Indirectly, TEA increases vagal nerve activity, which in turn slows down the progression of intestinal ischemia, consequently reducing the impact of the "second hit" caused by the translocation of intestinal bacteria and endotoxins into the bloodstream, which exacerbates acute pancreatitis. Despite these promising results, clinical data on the efficacy of TEA in acute pancreatitis remains insufficient. Moreover, the precise mechanisms by which TEA influences the progression and severity of acute pancreatitis are yet to be fully elucidated. In order to further validate the clinical therapeutic effects of TEA and gain a deeper understanding of its mechanisms, the investigators have conducted this clinical study.
