There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Patients who meet the inclusion criteria will undergo laparoscopic proximal gastric cancer radical surgery, and esophagogastric anastomosis will be performed using the ThTV method. Review the surgical video and record the time for making the extracorporeal muscle flap, tunnel passage time, and anastomosis time. The production time of the muscle flap is based on the electric knife incision of the muscle flap as the starting point, and successfully penetrating the muscle flap as the endpoint. The tunnel passes through time, pulling the residual end of the esophagus, and starting to pass through the gastric muscle flap tunnel as the time starting point. The complete placement of the gastric tube into the lower mediastinum is used as the time endpoint. The anastomosis time is calculated from the first needle of suturing the residual stomach and the posterior wall of the esophagus until the end of the plasma flap suturing. Record perioperative indicators such as surgical time, bleeding volume, and postoperative hospital stay. The definition of anastomotic stenosis is that in gastroscopy, those who cannot pass through the anastomotic site with ultra-fine endoscopy are judged as anastomotic stenosis. Postoperative pathology was performed using the 8th edition AJCC staging. Follow up every three months after surgery, including blood tests, liver and kidney function, and tumor markers. According to the situation, choose gastroscopy, upper gastrointestinal imaging, and chest abdominal pelvic enhanced CT. Evaluate postoperative reflux symptoms such as heartburn and sternal pain using the Visick grading system. Gastroscopy Los Angeles grading was used to evaluate postoperative reflux esophagitis.
The prognosis of locally advanced oral squamous cell carcinoma(OSCC ) is poor, and there are still many problems to be solved in the current treatment paradigm. Neoadjuvant chemotherapy combined with immunotherapy can significantly improve the pCR and MPR rates in patients with locally advanced OSCC. For patients who achieve pCR and MPR after neoadjuvant therapy and surgery, it is still hotly debated regarding whether to implement postoperative de-escalation radiotherapy. Neoadjuvant therapy is an ideal predictor of radiosensitivity. In theory, neoadjuvant therapy can eliminate microscopic lesions, thereby reducing the dose and volume of irradiation. Continuous hyperfractionated accelerated radiotherapy (CHART, based on hyperfractionated radiotherapy, increasing daily or weekly treatments and shortening the total treatment duration, but reducing the total dose), is to give a higher dose of radiation to tumor tissue in a shorter period of time, so as to overcome the accelerated reproliferation and inhibit the repair of sublethal damage of tumor cells. It is beneficial to improve the local control rate of tumor, control the acute injury of normal tissue and the yield acceptable late treatment-related complications. The specific protocol was as follows: high-risk CTV area (CTV1), 45Gy in total, fraction dose of 1.5Gy, twice a day, bioequivalent dose (BED) of 51.75Gy; Low-risk CTV area(CTV2), 39Gy in total , fraction dose of 1.3Gy, twice a day, BED of 44.07Gy; A total of 30 radiotherapy fraction were performed 10 times a week for 3 weeks.
The robotic surgery system, the most advanced technology in minimally invasive surgery, overcame some shortcomings of laparoscopic surgery and improved the flexibility and precision of liver resection. Several studies have demonstrated that the robotic system was safe and feasible in liver surgery and might be advantageous in complex hepatic vein and hilar dissection, operative bleeding control, and biliary reconstruction. Previous comparative studies found limited evidence for significantly improved outcomes in robotic liver resection (RLR) over laparoscopic liver resection (LLR) or open liver resection (OLR), considering the various degrees of difficulty in liver surgeries. This study aimed to evaluate safety and feasibility of robotic liver resection, by comparing it with LLR or OLR, and gain veritable and relevant data on the benefits of RLR.
Low levels of serum triiodothyronine (T3) thyroid hormones (T4) are a strong predictor of mortality and poor prognosis in critical care patients. Few reports, however, have focused on neurocritical patients. Patients with severe neurological diseases often experience more complications and exhibit higher mortality rates, and many studies have provided evidence for a low T3/T4 state being an important prognostic indicator in such cases; Lieberman et al. found that 87% of individuals with severe traumatic brain injury have thyroid function below the mid-normal range. Other researchers showed that low T3 syndrome is a predictor of poor prognosis in cerebral infarction patients; their findings indicated the central hypothyroidism and disturbance of thyroid hormone metabolism were involved. Low T3 syndrome is common in patients with brain tumors and has been shown to be associated with shorter survival in glioma patients. Despite these observations, however, whether the thyroid hormone abnormalities in the critically ill are a physiological adaptation or a pathological change, and whether hormone replacement therapy (HRT) can benefit such patients, remain to be established. As acute progression ceases, thyroid hormone levels may return to normal. This may imply that thyroid hormone supplements could improve the prognosis of patients with secondary hypothyroidism. Previous clinical studies have examined the effect of thyroid HRT on patients undergoing cardiac surgery; patients with malnutrition, heart failure, or acute renal failure; and premature infants with acute respiratory distress syndrome. Most of these past studies found no significant positive effects on prognosis, and no harmful effects either. Some smaller studies have demonstrated potential promise for the use of HRT; for example, one study showed that T3 supplementation in patients undergoing cardiac surgery could lead to less need for inotropic support and better hemodynamic parameters. There are no reports of thyroid HRT improving the prognosis of neurocritical patients with secondary hypothyroidism. The application of hormone replacement therapy in the treatment of neurocritical patients with secondary hypothyroidism remains controversial. This study aims to explore the safety and effectiveness of thyroid hormone replacement therapy in patients with spontaneous intracerebral hemorrhage and concomitant secondary hypothyroidism.
The goal of this clinical study is to evaluate the efficacy and safety of berberine ursodeoxycholate (HTD1801) compared to placebo in patients with type 2 diabetes inadequately controlled with metformin.

The goal of this clinical trial is to validate the effectiveness of the modified olfactory training device, the main questions it aims to answer are: Is it possible that the device can treat olfactory disorders in adults? Compared to the conventional device, how efficient is the modified olfactory training device for treating patients with olfactory disfunction?
This study, set up as a cross-sectional survey, seeks to delve into the disease burden and the demographic specifics of lower urinary tract symptoms (LUTS) among the male community in China. The investigators's main aim is to map out the overall and age-specific prevalence rates of LUTS within the Chinese male population. These insights are critical for understanding the public health dimensions of this condition. Moreover, the investigators plan to investigate several secondary aspects: the correlation of LUTS prevalence with factors like urbanization levels (rural vs. urban), geographical distribution, and lifestyle choices. Another significant focus will involve examining the treatment landscape for LUTS, looking at the portion of sufferers receiving treatment, the diversity in treatment durations, and the types of treatments employed (medication vs. surgery). This comprehensive analysis is intended to shed light on the prevailing management strategies for LUTS in China. The study is scheduled to unfold over 36 months and will comprise three pivotal phases: initial preparations, recruitment of subjects and collection of data, followed by the analysis of data and compilation of reports. The investigators will employ a range of methods such as questionnaires, physical exams, laboratory tests, imaging, and other medical evaluations to amass extensive data. This will allow the investigators to evaluate the prevalence of LUTS across various age groups among men and address the current gaps in epidemiological understanding.
