Transanal drainage tube (TDT) has the benefit of reducing intraluminal pressure after rectal surgery and may provide ideal regional environment for anastomotic healing. Postoperative C-reactive protein (CRP) trajectory has a high negative predictive value of 0.99 for ruling out anastomotic leak (AL). Previously, TDT was removed at the surgeon's own discretion. In the present study, we design a single arm study to investigate the safety and efficacy of CRP-guided TDT removal for AL prevention following laparoscopic anterior resection for rectal carcinoma
The primary objective of this study is to compare the effect of zimberelimab (ZIM) and domvanalimab (DOM) in combination with chemotherapy relative to pembrolizumab (PEMBRO) in combination with chemotherapy on progression-free survival (PFS) and overall survival (OS) in patients with untreated metastatic non-small cell lung cancer with no actionable genomic alteration.
In the 5G era with the revolutionary improvement of network speed, digital medical care has brought great convenience to health services. There is a lack of mobile medical data on cancer care worldwide. We designed an applet based on mobile intelligent electronic devices with a doctor-patient dual interface for the perioperative management of cancer patients and verified its applicability in the general population. This study aims to specifically improve the applet according to the characteristics of cancer patients, use it to accurately manage and intervene cancer patients, and establish a rapid doctor-patient communication platform, hoping to improve prognosis.
Compared with conventional artery sheath (TERUMO, Introducer II ), GlideSheath Slender® has more smaller outer-side diameter. The investigators suspected that use of the GlideSheath Slender® can reduce the incidence of distal radial artery occlusion in cardiovascular intervention via dTRA approach.
This is a Phase I, Open-Label, Multicenter, Dose Escalation and Expansion Study to evaluate the safety, tolerability, pharmacokinetics, and preliminary anti-cancer activity of ABM-1310 in patients with BRAF V600-Mutant advanced solid tumors. This study consists of two stages: dose escalation and dose expansion. During the dose escalation stage, a classic "3+3" design will be used to guide dose escalation to determine MTD and RP2D. The dose expansion stage will be initiated at the MTD or the optimal dose determined by the Safety Monitoring Committee (SMC ) as a fixed dose level (MTD or the optimal dose needs to be reviewed by the SMC and subjects are safe and tolerable at that dose level).
This project is the first application, which is applied as a single center project and applied according to the screening quantity. This project is a multi-omics approach to explore biomarkers associated with prognosis after secondary radical resection of recurrent and metastatic colorectal cancer. Main research objectives: 1. To detect DNA mutation and methylation in tumor tissues by NGS detection technology (the methylation dimension should be detected in adjacent tissues at the same time), and to explore specific molecular markers related to prognosis; 2. Using NGS test technology of blood in patients with preoperative and postoperative blood ctDNA mutations and methylation double dimension testing, respectively, to explore the preoperative and postoperative ctDNA mutations and the correlation between methylation status and recurrence, including but not limited to predict patients with recurrence of sensitivity, specificity, positive predictive value, negative predictive value and recurrence warning time and other indicators. Main contents: This study intends to include single site for the first time/organ metastasis after radical treatment and surgical indications again in patients with colorectal adenocarcinoma (including but not limited to spread to the liver, lung metastasis, peritoneal metastasis, lymph node metastasis and other organ metastasis), collected in patients with preoperative peripheral blood and tissue samples, tissue adjacent to carcinoma and postoperative peripheral blood, NGS detection technology was used to detect DNA and mutation in the relevant samples, combined with clinical treatment and prognosis information of patients, and then explore biomarkers for predicting recurrence risk.
Immunosuppressive (IS) agents are effective treatment to avoid acute or chronic rejection after pediatric liver transplantation. However, long-term side effect of IS intaking, like infection, kidney dysfunction, metabolic disorders and developmental retardation, should be aware, especially in pediatric recipients. Spontaneous immune tolerance is defined as recipients who cease to taking IS agents due to multiple reasons and the liver function maintained normal. However, the real ratio and safety of immune tolerance in pediatric liver transplantation recipients are rarely known. We would like to investigate the ratio and safety of spontaneous immune tolerance in pediatric liver transplantation recipients during long-term follow-up by constructing an immune tolerance cohort. In this cohort, long-term pediatric liver transplantation recipients with normal liver function and taking monotherapy of IS would be involved. The IS strategy would be monitored and adjusted according to the "Clinical guidelines for pediatric liver transplantation in China(2015)". For recipients suffering refractory virus infection, such as EBV or CMV infection, IS will be minimized to assist the clearance of virus until IS was weaned off. Since most of pediatric liver transplantation recipients may encounter chronic EBV or CMV infection within one year after transplantation, they may need IS minimization during follow-up. During the process of IS weaning off, liver function, immunological status and intrahepatic pathology will be closely monitored. If acute rejection or other complications were found, increase of IS dosage or other related treatments will be applied. Immune tolerance is defined as liver function and intrahepatic pathology maintain normal for more than one year after stop taking IS. At the end of study, the ratio of immune tolerance, acute rejection and all types of complications will be assessed.
The study aims to assess the effect of superselective adrenal arterial embolization on ventricular remodeling in primary aldosteronism without lateralized aldosterone secretion by comparing it with spironolactone therapy.
At present, it is recognized that statins are the cornerstone of treatment for the prevention of major cardiovascular events in patients with atherosclerotic cardiovascular disease (ASCVD); However, at the same time, the increased risk of long-term glucose tolerance and type 2 diabetes mellitus caused by statin therapy has attracted wide attention. The investigators' recent study found that the levels of glycosylated hemoglobin, insulin and C-peptide increased significantly with the extension of follow-up time in patients with hyperlipidemia. At the same time, serum and fecal bile acid metabolism profiles, especially secondary bile acid metabolism, were extensively changed, especially in ursodeoxycholic acid (UDCA), suggesting that the decrease of UDCA is a possible mechanism for statins to induce side effects of diabetes. According to this hypothesis, ursodeoxycholic acid combined with statins may improve the abnormal glucose tolerance caused by statins and maximize the benefit of statins. This study is a multicenter, prospective, randomized, parallel, double-blind placebo-controlled, cohort study. Taking ASCVD patients as the research object, the investigators will compare the changes of glycosylated hemoglobin, fasting blood glucose, fasting insulin, C-peptide and metabolomic indexes before and after the use of ursodeoxycholic acid combined with atorvastatin and atorvastatin alone and during follow-up, Further evaluate the changes of blood glucose related indexes before and after the use of ursodeoxycholic acid combined with atorvastatin and atorvastatin alone, clarify the possible mechanism and specific treatment targets of abnormal glucose tolerance caused by statin, and put forward a possible alternative treatment for the disorder of glucose metabolism caused by statin.
Background: Dexmedetomidine (DEX) is a highly selective 2-adrenergic receptor agonist with significant analgesia affection. This study is planned to explore the brain regions and functional neuronal network involved in promoting analgesia of Dexmedetomidine. Methods: Select 12 patients with the proposed intraoperative MR-guided radiofrequency ablation of epilepsy. The subjects were randomized into the Dexmedetomidine group (DEX group) (n=6) and the Opioid group (OPI group) (n=6). DEX group: continuous intravenously administered 1.5 µg kg-1 h-1 dexmedetomidine 15min before anesthesia induction, continuous infusion for 15min after anesthesia induction, and then Intraoperative functional magnetic resonance imaging scanning was started. OPI group: the equivalent administered speed 0.9% sodium chloride was continuously pumped for 15min before anesthesia induction, then induce and intraoperative fMRI scanning started after continuous 30min infusion. The intraoperative fMIR scan results were compared and analyzed to find the unique analgesic brain regions of DEX, and the differences of the functional neuronal network of analgesia effect between the two groups.
