Venlafaxine Combined With Education and Behavioral Intervention for Bladder Pain Syndrome

This study aims to compare two treatment plans for adults with bladder pain syndrome (also called interstitial cystitis), a disease that causes long-lasting bladder pain, frequent urination and urgent need to pee. All participants will receive standardized patient education and behavioral training to relieve urinary discomfort. Half of the participants will only get this behavioral intervention, while the other half will take oral venlafaxine in addition to the same behavioral training for 12 weeks. We will check patients' pain levels, urination frequency, sleep quality, mood and daily life ability at 1, 2, 6 and 12 weeks of treatment. The main goal is to see whether adding venlafaxine can better ease bladder pain and urinary symptoms without obvious side effects. This research will provide safer and more effective treatment suggestions for patients with bladder pain syndrome.

Endovascular Therapy for Cerebral Vasospasm After Aneurysmal Subarachnoid Hemorrhage

Cerebral vasospasm is a common and serious complication after aneurysmal subarachnoid hemorrhage and is an important cause of delayed cerebral ischemia and poor neurological outcomes. Although standardized medical management is widely used, effective treatment options for cerebral vasospasm remain limited. Endovascular treatment, including intra-arterial drug infusion and mechanical angioplasty, may relieve vasospasm and improve cerebral perfusion after aneurysmal subarachnoid hemorrhage. However, most available evidence comes from retrospective or observational studies, and high-quality randomized evidence remains insufficient. Milrinone is a phosphodiesterase inhibitor with multiple potentially beneficial effects, including vasodilation, positive inotropic activity, anti-inflammatory properties, and endothelial protection. These effects may make milrinone a promising therapeutic agent for relieving cerebral vasospasm, reducing delayed cerebral ischemia, and ultimately improving clinical outcomes after aneurysmal subarachnoid hemorrhage. This study is a multicenter, prospective, randomized controlled clinical trial designed to evaluate whether early continuous milrinone-based endovascular therapy improves outcomes in patients with cerebral vasospasm after aneurysmal subarachnoid hemorrhage. Eligible participants will be randomly assigned to receive either standardized medical management alone or milrinone-based endovascular therapy plus standardized medical management. In the intervention group, patients will receive intra-arterial milrinone during endovascular treatment, with mechanical angioplasty when clinically indicated, followed by continuous intravenous milrinone infusion for 72 hours after intra-arterial administration. The study will evaluate whether this continuous treatment strategy reduces poor neurological outcomes at 3 months after randomization. It will also assess the effects of treatment on delayed cerebral ischemia, vasospasm resolution, cognitive function, quality of life and so on. The results of this trial may provide high-quality evidence for early continuous milrinone-based endovascular therapy as a treatment strategy for cerebral vasospasm after aneurysmal subarachnoid hemorrhage.

The Efficacy and Safety of Pregabalin and Mirogabalin in Patients With Fibromyalgia

Fibromyalgia (FM) is a chronic pain syndrome characterized by widespread pain, fatigue, and emotional disorders. Its onset is related to factors such as central sensitization and imbalance of neurotransmitters. The current mainstream treatments include pregabalin, but the efficacy of pregabalin is limited, with only 25%-40% pain relief rate, and adverse reactions are common. Mirogabalin, a new highly selective α2δ ligand, has shown potential in animal models or preliminary clinical trials, but there is insufficient evidence for its application in FM. This study aims to explore the effectiveness and safety of pregabalin or mirogabalin in treating FM, with the aim of providing a better treatment option for FM patients.

Pre-incisional Infiltration With Ropivacaine Plus Triamcinolone for Relieving Postoperative Pain After Laparoscopic Surgery

Incisional infiltration is the simplest, safest, and most effective anesthesia method for preventing incision pain after laparoscopic surgery, but even using long-acting local anesthetics, the effectiveness of postoperative analgesia can only last for a relatively short period of time. Studies have shown that up to 80% of patients experience postoperative pain following laparoscopic surgery due to inflammation caused by surgical incisions and surrounding tissues, necessitating pharmacological relief. Inflammatory mediators released from the soft tissues around laparoscopic incisions not only significantly alters the chemical microenvironment at the peripheral terminals of nociceptors, directly inducing pain, but also sensitizes afferent fibers, contributing to peripheral sensitization. Preemptive incisional infiltration using local anesthetics with corticosteroids which have potent local anti-inflammatory properties may play a key role in preventing or reducing postoperative pain. The objective of this trial is to determine whether preemptive incisional infiltration with ropivacaine plus triamcinolone is superior to ropivacaine alone in relieving postoperative pain for adults undergoing laparoscopic surgery. We also compare the effects of the two intervention measures on postoperative pain management, patient safety, and recovery quality.

Pre-incisional Infiltration With Ropivacaine Plus Diprospan for Relieving Postoperative Pain After Thoracoscopic Surgery

Video-assisted thoracoscopic surgery (VATS) is less invasive compared to traditional thoracotomy, but it is still reported that the incidence of acute pain following VATS exceeds 80%. Inadequate postoperative analgesia may trigger a series of adverse physiological stress responses, increase the occurrence of postoperative complications, and affect the rehabilitation process. If acute pain is not managed promptly and sufficiently, nearly one-quarter of patients may develop chronic pain, impacting normal life and sleep quality after discharge. Acute pain after VATS is mainly caused by the release of inflammatory mediators after soft tissue injury at the surgical site, which activates peripheral pain receptors and leads to abnormal action potentials transmitted along A δ and C fibers. Inflammatory mediators released from the soft tissues around incisions not only significantly alters the chemical microenvironment at the peripheral terminals of nociceptors, directly inducing pain, but also sensitizes afferent fibers, contributing to peripheral sensitization. Incisional infiltration is the simplest, safest, and most effective anesthesia method for preventing incision pain after VATS, but even using long-acting local anesthetics, the effectiveness of postoperative analgesia can only last for a relatively short period of time. To improve the efficiency of local incision infiltration in postoperative analgesia, at least two issues need to be addressed: prolonging the duration of analgesia and reducing inflammation of nerve surrounding tissues. Numerous studies have shown that glucocorticoids not only can achieve anti-inflammatory and analgesic effects by inhibiting inflammatory cytokines and inflammatory responses but also can prolong the duration of action of local anesthetics. Preemptive incisional infiltration using local anesthetics with corticosteroids which have potent local anti-inflammatory properties may play a key role in preventing or reducing postoperative pain. The objective of this trial is to determine whether preemptive incisional infiltration with ropivacaine plus diprospan is superior to ropivacaine alone in relieving postoperative pain for adults undergoing VATS. The investigators also compare the effects of the two intervention measures on postoperative pain management, patient safety, and recovery quality.

Oliceridine for Gastrointestinal Dysfunction

Gastrointestinal dysfunction is common in patients after major surgery, especially for neurosurgery. It was reported 80% of neurosurgery patients could be combined with gastrointestinal dysfunction, and it may relate to old age, surgery time, and factors of anesthesia and surgery. Meanwhile, postoperative constipation, nausea, and vomiting induced by gastrointestinal dysfunction may increase the intracranial bleeding. Oliceridine could activate mu opioid receptors without the interaction of (beta)arr2-muOR, and may reduce the gastrointestinal dysfunction, but a limited study has illustrated this topic. Thus, this study is conducted to explore whether oliceridine could reduce the gastrointestinal dysfunction vs. sufentanil in patients undergoing neurosurgery.

Dosimetry, Safety, and Efficacy Study of [177Lu]Lu-XT771 in Patients With Recurrent Glioblastoma

The primary objective of this study is to evaluate the dosimetry, safety, and tolerability of the investigational radiopharmaceutical \[177Lu\]Lu-XT771 in patients with recurrent glioblastoma, an aggressive form of brain cancer. \[177Lu\]Lu-XT771 is designed to specifically target and deliver beta radiation directly to tumor cells that overexpress carbonic anhydrase IX and XII (CA IX and CA XII). This early-phase, investigator-initiated trial will enroll a small group of approximately 3-5 patients, each receiving a single dose of \[177Lu\]Lu-XT771. The drug will be administered locoregionally via an implanted Ommaya reservoir, directly into the tumor cavity. Following administration, patients will be closely monitored using single-photon emission computed tomography/computed tomography (SPECT/CT) to assess the biodistribution of the drug and to quantify the absorbed radiation dose to both the tumor and normal organs. The study will also document all adverse events to characterize the safety profile of the treatment and will provide a preliminary assessment of its anti-tumor activity, as measured by progression-free survival. The information gathered from this exploratory study will be used to determine the recommended safe starting dose for future Phase I clinical trials.

Stellate Ganglion Block and Prognosis of Neurological Function After Subarachnoid Hemorrhage

The incidence of cerebral vasospasm after aneurysm subarachnoid hemorrhage (aSAH) is as high as 70%; cerebral vasospasm(CVS) is closely related to delayed cerebral ischemia (DCI), which is one of the important reasons for poor outcomes in patients with aSAH. In recent years, it has been reported that stellate ganglion block(SGB) can effectively alleviate cerebral vasospasm(CVS), reduce cerebral blood flow velocity and increase cerebral perfusion in patients with aneurysm subarachnoid hemorrhage(aSAH)。However, whether the alleviation of CVS after SGB is beneficial to the long-term neurological prognosis has not been confirmed Therefore, a prospective randomized controlled study is needed to further explore the role of SGB block in improving the outcomes of patients with aSAH.

Comparison of Cumulative Opioid Consumption Between Variable-Rate Feedback Infusion and Fixed-Rate Basal Infusion Modes of Intravenous PCA Following Mixed Surgery

Perioperative pain management affects patient recovery. However, the rate of moderate to severe postoperative pain is as high as 73.8%, which hinders recovery and increases the risk of complications. Although opioids are the first-line analgesics, excessive use leads to adverse reactions. The traditional fixed-rate PCA mode is difficult to match the changes in postoperative pain. This study will compare different PCA mode optimization strategies, assuming that they can reduce opioid dosage, improve analgesic effect, and reduce adverse reactions, providing high-quality evidence-based basis for postoperative analgesia and promoting individualized and intelligent management.
