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.
Intense pulsed light (IPL) has been reported to improve signs and symptoms of dry eye (DE). Additionally, meibomian gland secretion of lipids has been observed to improve through the use of IPL. Diquafosol ophthalmic solution (DQS) stimulates P2Y2 receptors on the ocular surface, which enhances mucin secretion from goblet cells. Therefore, tear film stability and hydration of the ocular surface can be achieved independent from lacrimal glands function. The purpose of this prospective study was to evaluate and compare the effects of IPL (IPL group), DQS (DQS group) and IPL in combination with DQS (IPL+ group) in participants with persistent DE. Tear film lipid layer (TFLL), non-invasive breakup time (NITBUT), tear meniscus height (TMH), corneoconjunctival staining score (CS), meibum gland (MG) function, conjunctival hyperemia (RS score), ocular surface disease index (OSDI) will be assessed and compared at baseline, day-14, and day-28.
The goal of this clinical trial is to assess the efficacy and safety of hippocampus-targeted deep brain stimulation (DBS) in treatment-resistant schizophrenia. The main question it aims to answer are: - whether patients with treatment-resistant schizophrenia can benefit from hippocampus-targeted DBS; - what is the neural and electrophysiological mechanism underlying the treatment effect of hippocampus-targeted DBS.
The purpose of this study is to enable non-invasive early detection of ovarian cancer in high-risk populations through the establishment of a multimodal machine learning model using plasma cell-free DNA fragmentomics. Plasma cell-free DNA from early stage ovarian cancer patients and healthy individuals will be subjected to whole-genome sequencing. Five diferent feature types, including Fragment Size Coverage (FSC), Fragment Size Distribution (FSD), EnD Motif (EDM), BreakPoint Motif (BPM), and Copy Number Variation (CNV) will be assessed to generate this model.

The primary objective of this study is to evaluate the efficacy of TV-44749 in adult participants with schizophrenia. A key secondary objective is to further evaluate the efficacy of TV-44749 based on additional parameters in adult participants with schizophrenia. A secondary objective is to evaluate the safety and tolerability of TV-44749 in adult participants with schizophrenia Another secondary objective of this study is to evaluate the efficacy of TV-44749 from baseline to endpoint in Period 1 in adult participants with schizophrenia. Total study duration is up to 61 weeks, and treatment duration is up to 56 weeks, with weekly visits during the first 8 weeks and then monthly in-clinic visits with weekly calls during the remainder of the treatment period.
In preclinical study, investigators have demonstrated that the newly developed pan-T booster (harbouring CD40 agonist and one T cell costimulator agonist) co-expressing MSLN CAR T cell possess more powerful antitumor activity than previously reported MSLN-CAR T cells. In this clinical trial, enrolled patients receive an initial dose of pan-T booster co-expressing MSLN CAR T cells at 1×10^6 cells/kg based on the basic principle of dose escalation design, in order to evaluate the safety, feasibility, pharmacokinetics/pharmacodynamics, and efficacy of pan-T booster co-expressing MSLN CAR T cell in vivo.
Patients undergoing major spinal surgery usually experience moderate-to-severe postoperative pain. Inadequate pain control may lead to severe complications. Dexamethasone as an adjunctive infiltration to local anesthesia (LA) presented a superior analgesic benefit compared with LA alone in various types of surgeries. However, a recent meta-analysis showed that the additional analgesic effect of dexamethasone in incision/wound infiltration was only statistically significant, but not clinically significant, and the overall benefits were marginal. Compared with dexamethasone, dexamethasone palmitate emulsion (DXP) is a targeted lipo-steroid with stronger anti-inflammatory effect, longer-acting duration and fewer adverse effects. To date, no studies have evaluated the additive analgesia effects of DXP on incision infiltration in major spinal surgery. The purpose of this trial is to determine whether preemptive co-infiltration of DXP emulsion and ropivacaine in surgical incision will further reduce postoperative opioid requirements and pain score after spinal surgery than that of ropivacaine alone.
Gastrointestinal tumor is one of the highest incidence of malignant tumors in our country, with the incidence increasing year by year. Laparoscopic gastrointestinal surgery ,due to having less bleeding ,small trauma ,Rapid recovery ,has become the main means for the treatment of gastrointestinal surgery. Under general anesthesia, mechanical ventilation can lead to repeated mechanical dilation of alveoli, which can lead to mechanical injury of alveolar epithelium, reduce lung compliance, affect lung function, and increase postoperative complications and hospital stay of patients. Glycopyrrolate acts selectively on M1 and M3 receptors, and is 3-5 times more selective to M3 and M1 receptors than M2 receptors. Therefore, as preoperative medication for elderly patients, it has less effect on the cardiovascular system and can stabilize the heart rate,compared with atropine.However, its influence on the respiratory system in the field of anesthesia is only limited to the study of inhibiting glandular secretion at present, and there are no clear reports on the study of respiratory mechanics .The purpose of this study was to investigate the effects of glycopyrrolate on lung function and respiratory mechanics in elderly patients after general anesthesia, in order to guide clinical medication.
It is an observational, case-control study aimed at early-detection of multiple myeloma and constructing a prognostic model of multiple myeloma. The study will enroll approximately 398 participants including patients with multiple myeloma, patients with benign hematologic disorders and healthy participants.
The purpose of this study is to assess the effect of food on the single-dose PK of SHR3824, SP2086 and metformin in the HR20031 FDC tablets in healthy subjects.
