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.
This project will use literature analysis, expert research, real-world data mining and other methods to investigate the current status of the application of antimicrobial aerosolized inhalation in healthcare institutions, combine expert recommendations and real-world data analysis results to explore potential risk points in the process of antimicrobial aerosolized drug delivery, and sort out the key points of drug use management in healthcare institutions and the key points of regulatory recommendations for healthcare institutions.
The purpose of this study is to explore the efficacy and safety of endoscopic scissors cutting nasobiliary ducts in the treatment of malignant hilar biliary tract stenosis
The meibomian gland (MG) is a modified sebaceous gland located in the upper and lower eyelids. The grades of MG loss (i.e. meiboscore) is calculated as the ratio between the area of the MGs and the eyelids, and this calculation is based on the two-dimensional digital infrared images.In the current formula, the area of the eyelid is the denominator. However, because the eyelids need to be flipped over for the examination and evaluation, and there may be interobserver variability in the measurement of the area of the eyelids. Aging and involutional eyelid disorders, such as ptosis, ectropion, and entropion, may lead to laxity or deformation of eyelids, and impact the shape and area of eyelid area consequently.These factors could cause inaccuracy in current evaluation method, and impact the grading and evaluation of treatment efficacy of MGD, especially in self-controlled studies, such as in clinical trials. In this study, the investigators propose to use a modified calculation formula for the grading of MGs. The investigators could measure the white to white (WTW) distance of cornea, and then calculate the area of cornea (i.e. corneal base area) accordingly.Unlike the eyelid, the WTW distance does not change significantly during aging or between sexes.Thus, the investigators hypothesize that using the corneal base area as the new denominator in the formula for the grading of MG loss is a better way comparing with the conventional method.
This is a real-world study to explore the safety and the efficacy of washed microbiota transplantation （WMT） for patients with Clostridioides Difficile Infection （CDI）.
This is a single-center, randomized, double-blind, placebo-controlled, dose-exploring clinical study to explore the safety and efficacy of washed microbiota transplantation (WMT) for patients with chronic constipation.
Peripheral venous catheters are the most commonly used vascular access devices in healthcare today, including indwelling needles, mini-midline catheters, and medium-length venous catheters. Peripheral venous catheters are required due to clinical needs for prescribed intravenous treatments, medications, surgical procedures, or diagnostics, such as computed tomography scans, etc. One study noted that more than 70% of hospitalized patients had indwelling needles placed. However, post-placement failure of indwelling needles occurs in 30%-50% of patients before completing treatment, unplanned catheter failure occurs in 69% of patients before completing treatment, and there is a 30%-60% risk of various complications. And patients are often subjected to repeat catheter placement, such as improper catheter placement or improperly entered medications. In addition, catheterization is prone to infectious and noninfectious complications, and the risk of phlebitis increases 4.4-fold when catheters are reintroduced.Tan et al. found that the average number of indwelling needle insertions per patient admission was 2.82, and therefore, approximately 44% of adult patients required more than one indwelling needle to complete IV therapy during their hospitalization. According to Helm et al, multiple insertions of indwelling needles per patient lead to unnecessary pain and anxiety, and multiple attempts per insertion further increase the risk of complications. These also lead to prolonged hospitalization, additional healthcare costs, pain, anxiety, and other adverse experiences.
About 40 people will participate in the study, which will be conducted at Southern Medical University Southern Hospital. All subjects need to sign an informed consent form before screening, and successful subjects can enter the study. Experimental and control subjects were treated according to the protocol. Treatment was held until the participant entered a follow-up period, or until any of the withdrawal criteria were met. According to conventional clinical practice, the study needs to evaluate the patient's subjective perception and soft and hard tissue changes at 3 months, 6 months, and 1 year after successful implant placement. The specific process is divided into: 1. Screening period: All subjects need to complete the relevant examinations of the screening period before enrollment, and screen according to the admission criteria. (1) Sign informed consent; (2) Record demographic data: date of birth, gender, initials; (3) Medical history and physical examination: collection includes understanding of any current or past diseases, medications, drug allergy history, surgical history, radiotherapy and chemotherapy history, ethnic background, smoking history, whether alcoholism, oral hygiene habits and oral examination, etc.; (4) Among them, oral examination includes the whole oral health before and after surgery and oral and maxillofacial CBCT imaging examination; 2. Treatment period: the control group underwent transalveolar crest parietal maxillary sinus floor lift immediately after implants; The experimental group underwent implant implantation after 6 months of transalveolar crest parietal maxillary sinus floor lift. 3. Follow-up period: The study needs to evaluate the subjective feelings and soft and hard tissue changes of patients at 3 months, 6 months and 1 year after implant placement.
