There are about 13473 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.
Orthopedic surgeries are considered to be discomfortable and the sense of fear and anxiety of patients who already have preoperative anxiety may be aggravated by intraoperative stimulation, which may contribute to postoperative complications. Previous studies have found that high anxiety predicts increased sedative requirements. Therefore, the investigators explored the relationship between anxiety and intraoperative butorphanol requirements and the investigators evaluated the specific sedative requirement which can keep satisfactory sedative state for patients by preoperative anxiety score
The purpose of this study is to evaluate the response of toripalimab , a PD1 antibody, in participants with POLE or POLD-mutated and non microsatellite instability (non-MSI-H) advanced solid cancers.
Comparing the accuracy and speed of 3DV+TPS software with imported TPS and domestic TPS to outline the contours of crisis organs, it is proved that 3DV+TPS has superiority compared with domestic TPS, and it has non-inferiority compared with imported TPS, indicating that the software can improve contour sketching accuracy. And speed, reduce the burden on doctors, improve medical efficiency.
A defect in the hatching stage is considered an important cause of implantation failure. Therefore, assisted hatching (AH), which involves artificial disruption of the zona pellucida, has been proposed as a method for improving the capacity of the embryo to implant. But the advantage of using laser to facilitate the hatching process of embryos in ART practice is debatable, and an optimum strategy for performing LAH remains elusive. Therefore, the aim of this study was to evaluate the effects of laser-assisted hatching(LAH) on clinical outcomes. Patients were randomly divided into control and LAH groups. The zona pellucida was thinned or drilled with a diode laser. Relevant parameters are recorded to evaluate the validity of LAH in ART.
Good-quality embryos are critical for the success of in vitro fertilization (IVF). But, to date, there is no report of the effect of different diameters denuding pipette on the embryos quality. To investigate the effect of denuding pipette in IVF outcomes, we plan to recruit women undergoing IVF treatment cycles and classified them into two groups according to the different diameters. Consequently, the rate of fertilization, zygotes cleaved, top quality embryos on D3, and blastocysts obtained were recorded.
Most fertilization failures after ICSI are caused by failure of oocyte activation defects. But, to date, there is no effective method to overcome this obstacle. To investigate the effect of mechanical stimulation on fertilization failures, investigators plan to recruit women undergoing ICSI treatment cycles. The retrieved sibling oocytes from the patients were randomly divided into two groups. The control group conducted the standard ICSI procedure, while the experimental group conducted the modified ICSI procedure.Consequently, the fertilization rate, 2PN (two pronuclei) rate, 1PN rate, oocyte degradation rate,and exploitable embryos on D3 were recorded to evaluate ICSI cycle outcomes.
To date, several studies have focused on the use of transcranial direct current stimulation(tDCS) in patients with impaired consciousness.However,its therapeutic effects have been variously documented.So,in this study ,investigators explore the effects of tDCS.
BACKGROUND: Few researches have manifested that intravenous (IV) lidocaine or dexmedetomidine decreased the incidence of postoperative nausea and vomiting (PONV). The investigators investigated whether IV lidocaine plus dexmedetomidine infusion could better reduce the incidence of PONV after laparoscopic hysterectomy. METHODS: One hundred and twenty women with elective laparoscopic hysterectomy were randomly divided into two groups: patients in the lidocaine combined with dexmedetomidine group (LD group, n=60) received lidocaine (1.5 mg/kg loading, 1.5 mg/kg/h infusion) and dexmedetomidine (0.5 μg/kg loading, 0.4 μg/kg/h infusion) respectively. Patients in the control group (CON group, n=60) received the equal volume of saline. Primary outcome was the incidence of the first 48 h nausea, vomiting and PONV after surgery. The secondary outcomes included perioperative propofol and remifentanil consumption, postoperative fentanyl requirement, Ramsay sedation score, and bradycardia during post-anaesthesia care unit (PACU) stay.
This is a phase Ia/Ib, open-label, multiple-dose, dose-escalation and expansion study to evaluate the safety, tolerability, pharmacokinetics and anti-tumor activity of CS1003 in subjects with advanced solid tumors or lymphoma.
This study is a prospective, registry trial aimed to compare the clinical and angiographic outcomes of OCT-guided and angiography-guided PCI in patients with coronary DES-ISR.
