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.
The standard method for localizing non-palpable breast cancer is currently preoperative wire-guided localization, its positive margin rate still remains around 20-50%. This study aims to compare the accuracy and efficacy of wire vs. combined breast tissue markers in localizing non-palpable breast cancer.
The investigators aim to establish a clinical database and biobank for elderly patients with multiple diseases. The collected data will include demographic information, comorbidity characteristic, FRAIL scale, age-adjusted Charlson comorbidity index, relevant blood tests, the results of imaging examination, prescription of drugs, length of hospital stay, number of overall rehospitalizations and death. With this database, the investigators intend to formulate an individualized treatment strategy for these patients.
This study included cataract patients who underwent toric intraocular lens (IOL) implantation, which aimed to evaluate the stability and clinical visual quality of toric IOLs.
Postoperative delirium (POD) remains one of most common complication in elderly patients receiving surgery, which is characterized by acute and fluctuating change in the level of cognition and consciousness. Previous studies have shown that surgery and anesthesia-induced acute peripheral inflammation and neuroinflammation may lead to delirium after surgery. Systemic Inflammation Response Index (SIRI) is a more easily accessible and comprehensive inflammation marker derived from monocyte, neutrophil, and lymphocyte count, which has been investigated to assess the prognosis of cancer and infectious diseases. However, the relationship between SIRI and POD has yet to be investigated.
This research is designed to determine if experimental treatment with Antibody-drug conjugate, AZD5335, alone, or in combination with anti-cancer agents is safe, tolerable, and has anti-cancer activity in patients with advanced tumors
The purpose of this study is to test whether spraying the hand of patients by use of the novel electrolyzed water spray will decrease the number of bacteria E-coli and the virus titer of an attenuated human flu virus.
The goal of this clinical trial is to compare in resectable liver metastases colorectal cancer patients.The main question it aims to answer is to investigate whether the progression-free survival (PFS) of resectable colorectal liver metastasis (CRLM) patients with positive ctDNA after surgery is superior with the combination of adjuvant chemotherapy and maintenance therapy compared to adjuvant chemotherapy alone.
The goal of this observational study is to test in patients with resectable rectosigmoid cancers. The main question it aims to answer is establishment of a feasibility model for predicting natural orifice specimen extraction surgery (NOSES) based on machine learning.
The goal of this observational study is to compare the differences in the features of cerebral multifrequency EIT(cMFEIT) images between healthy subjects and patients with brain diseases and to explore the possibility of applying multifrequency EIT to intracranial abnormality detection.16 healthy volunteers and 8 patients with brain diseases were recruited as experimental subjects, and the cerebral EIT data of 9 frequencies in the range of 21 kHz - 100 kHz of all subjects were acquired with an EH-300 MFEIT system.
This study will evaluate the efficacy, safety, pharmacokinetics(PK) ãpharmacodynamics(PD) and ADA of MIL62 compared with placebo in participants with systemic lupus erythematosus.
