Clinical trials

This study aims to explore whether the application of low-dose HCG in luteal support can improve the pregnancy outcomes of natural cycle frozen embryo transfer in obese patients

This study is a prospective, single-arm, phase II exploratory clinical trial. The primary endpoint of this study is to evaluate the pathological complete response (pCR) rate after surgery and to assess the safety of neoadjuvant therapy with adebrelimab combined with platinum-based chemotherapy in patients with locally advanced resectable esophageal squamous cell carcinoma (ESCC) at the Second Qilu Hospital of Shandong University. The primary endpoint of this clinical trial is the pathological complete response (pCR) rate, defined as the absence of residual viable tumor cells in the resected specimen, including lymph nodes (ypT0N0M0). Secondary endpoints include the major pathological response (MPR) rate, objective response rate (ORR), treatment-related adverse events (TRAEs) and immune-related adverse events (irAEs), as well as quality of life (QOL) assessments during neoadjuvant immunochemotherapy (nICT). MPR is defined as less than 10% residual viable tumor cells in the primary tumor bed following neoadjuvant therapy and resection. ORR represents the percentage of patients achieving complete response (CR) or partial response (PR). Other secondary measures include the tumor downstaging rate, surgery rate, R0 resection rate (defined as no residual tumor at the resection margins), and perioperative complication rate. Furthermore, overall survival (OS) and relapse-free survival (RFS) are considered exploratory endpoints in this study. By evaluating these diverse endpoints, the investigators aim to comprehensively assess the efficacy, safety, and overall impact of the nICT approach in patients with locally advanced resectable ESCC. Additionally, it is planned to construct 20 pairs of esophageal squamous cell carcinoma and adjacent normal esophageal squamous epithelial organoids, laying the groundwork for future in-depth exploration of the mechanisms underlying esophageal carcinogenesis and progression, as well as functional studies of specific genes.

With the decreasing of birth rate and population in our country, population problem has become a long-term and strategic problem. In addition to the decrease in the number of women of childbearing age and the impact of unmarried women, the increase in the incidence of reproductive disorders and the delay of marriage and childbearing are also important factors leading to the continuous decline of the birth population in China. Among them, ovarian aging is a key factor causing female fertility difficulties. Therefore, establishing an effective prevention and treatment strategy for ovarian aging is of great significance for improving female reproductive health and serving the national population strategy. Recently, several supplements have been found to promote folliculogenesis and improve oocyte quality. However, to date, there is no approved therapeutic agent for the treatment of ovarian aging. Therefore, it is urgent to develop effective strategies for the prevention and treatment of ovarian aging. Salidroside is the main active component of Chinese medicine Rhodiola, and its content is highest in the root of rhodiola, which is also the main medicinal part. The main efficacy of salidroside in traditional Chinese medicine is to benefit qi, promote blood circulation, unblock pulse and relieve asthma. At the same time, in basic research, more and more experiments have shown that salidroside has a variety of pharmacological properties, including anti-hypoxia, anti-fatigue and anti-aging effects, anti-cancer, anti-inflammatory, anti-oxidation, antiviral and so on. These pharmacological effects suggest that salidroside may be an effective drug for the prevention and treatment of atherosclerosis, Parkinson's disease, Alzheimer's disease, pneumonia and other diseases. In terms of aging, it has been confirmed that salidroside supplementation can prolong the life span of pseudogill oryzias zhan and rescue premature aging of human skin fibroblasts, etc., which further confirms. The aim of this study is to investigate the efficacy of salidroside as an adjuvant drug in improving the pregnancy outcomes of fresh embryo transfer in high childbearing age patients with poor ovarian response by comparing the pregnancy outcomes of fresh embryo transfer between salidroside group and blank control group. This pragmatic clinical study is expected to improve pregnancy outcomes of fresh embryo transfer cycles in women of advanced childbearing age with poor ovarian response.

At present, there is little epidemiological information on osteoporosis in the elderly population of Shandong Province, especially the lack of systematic research on the role of bone metabolism and biochemical indicators in the diagnosis and prognosis of osteoporosis in the elderly population of Shandong Province. The group intends to conduct a study on the epidemiological characteristics of osteoporosis patients and the significance of bone metabolism biochemical indexes in the diagnosis and prognosis of osteoporosis in elderly people in Shandong Province, which includes 1) assessing the prevalence of osteoporosis and the risk factors associated with osteoporosis in the community population, and 2) exploring the role of bone metabolism biochemical indexes in the diagnosis and prognosis of osteoporosis in the hospitalised population. Expected outcomes include the establishment of a database of community and inpatient populations in Shandong Province, publication of research papers, and participation in academic conferences at home and abroad. The database will collect and organise data on osteoporosis in the community and inpatient osteoporosis in Shandong Province, and provide support for subsequent data analysis and research.

Some patients with impaired lung function require minimally invasive surgical treatment, including those with lung cancer, benign lung tumors, pneumothorax, or lung volume reduction surgery. Patients with borderline lung function often cannot be extubated immediately postoperatively under conventional treatment models. These patients typically need to be transferred to the surgical ICU for close monitoring. However, positive-pressure mechanical ventilation with an endotracheal tube carries risks of further airway injury and persistent air leakage from the lung surface, leading to a high incidence of postoperative respiratory failure. Non-intubated minimally invasive surgery (tubeless), which preserves spontaneous breathing without endotracheal intubation, avoids the physical stimulation of intubation and the airway damage caused by mechanical ventilation. This approach may reduce the incidence of postoperative airway injury and respiratory failure, potentially expanding the indications for minimally invasive lung surgery, lowering postoperative complication and mortality rates. The aim is to further clarify the surgical indications for non-intubated single-port minimally invasive surgery in patients with impaired lung function, the decision-making criteria for postoperative ICU transfer, and the safety and feasibility of this comprehensive management approach.

Arthroscopic hip surgery is being increasingly performed to treat both intraarticular and extraarticular hip diseases. Despite the minimally invasive approach, patients undergoing arthroscopic hip surgery still suffer severe pain due to the complex nature of hip innervation. Postoperative pain reduces patient satisfaction and delay patient recovery and discharge. The efficacy of regional anesthesia techniques in postoperative pain management have been proved in various surgeries. However, it remains controversial whether or not peripheral nerve blocks can significantly improve postoperative analgesia after hip arthroscopy. Several studies have shown that the fascia iliac block cannot improve postoperative analgesia for hip arthroscopy because it blocks only some branches of the lumbar plexus but not the sacral plexus. Circum-Psoas Block (CPB) which has been defined in recent years is able to block the lumbar plexus nerves as well as sacral plexus such as the sciatic, superior gluteal, and inferior gluteal nerves. Therefore, the investigators predict that it can provide effective postoperative analgesia for hip arthroscopy. In this study, the researchers aim to investigate the effectiveness of CPB in hip arthroscopy.

As China's society ages faster, the number of elderly patients undergoing spinal fusion surgery will gradually increase. Since elderly patients are at higher risk of postoperative complications than younger patients, minimizing complications after spinal fusion becomes a priority in postoperative rehabilitation. The purpose of this prospective cohort study is to develop an enhanced recovery after surgery program including individualized perioperative smoking cessation strategies in Chinese elderly undergoing spinal fusion.

We aimed to evaluate the effect of ERAS nursing program on self-reported outcomes of patients undergoing minimally invasive lung cancer surgery, and compared the differences in length of hospital stay, complications, and readmission rate between ERAS and non-ERAS nursing programs

Surgery with or without neoadjuvant therapy is usually used as the treatment for resectable esophageal cancer or esophageal- gastric junction cancer. Patients who have a poor response to neoadjuvant therapy and have an incomplete (R1) resection or have metastatic lymph nodes in the resection specimen (N+) are especially at risk of recurrence, to continue with the chemotherapy± radiotherapy is often used in these cases. However, the overall survival is still poor. We designed a prospective randomized controlled tial to study whether immunotherapy could be used with chemotherapy after surgery to improve overall survival. The primary endpoint ofthe study is disease free survival, with secondary endpoints of overall survival, safety and toxicity, and quality of life.

Objective: The adoption of Enhanced Recovery Surgery programs in lung resection is relatively recent with limited outcome data. This study aimed to determine the impact of an Enhanced Recovery Surgery pathway on short- term and long- term results in patients undergoing lung resection for primary lung cancer. Methods: A Randomized Controlled Trial was designed to collect the perioperative data on consecutive patients undergoing lung resection for primary lung cancer. Patients will be randomizely assigned to the ERAS- Group and Control- Group. Short-term and long- term effect will be compared between the two groups.

Surgerys used in thymectomy for myasthenia gravis and anterior mediastinal tumours have become much less invasive in recent years. In our study, the surgical technique which resected the thymus below the xiphoid process and the technique which was regarded as conventional video- assisted thoracoscopic surgery (VATS) thymectomy was compared.

Background: We aimed to evaluate the combination of inflation- deflation method and fluorography with the ICG injection in the tubeless minimally invasive segmentectomy (no intubation, VATS or Robotic). Methods: A one- armed, prospective randomized controlled study was designed. The intersegmental plane was not so clear during the tubeless minimally invasive segmentectomy, and the presentation of the plane sometimes cost more time. This study will evaluate consecutive patients with the combination of inflation- deflation method and fluorography with the ICG injection.

To compare the safety/efficacy of the robotic-assisted lobectomy/segmentectomy (RAL/S) with the video-assisted lobectomy/segmentectomy (VAL/S) for lung resection. Video-assisted lobectomy/segmentectomy (VAL/S) for lung resection is divided into uniport group and multiple- port group.
