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.
to investigate the efficacy and safety of opioid-free anesthesia for non-small-cell lung cancer resection and its underlying clinical value
The investigators collected clinical data and serum samples of patients with polycystic ovary syndrome in this study, used statistical software such as SPSS for data analysis, and used experimental techniques such as ELISA to detect serum samples, aiming to explore the relationship between the body anthropometry, glucose and lipid metabolism, gonadal hormones and body fat distribution in patients with polycystic ovary syndrome and to discovery new biomarkers and promote the realization of more accurate personalized medicine.
Breast cancer (BC) is one of most prevalent malignant tumors in the world. According to the 2020 edition of the global cancer statistics report, the incidence rate of BC has overtaken lung cancer to become the most commonly diagnosed cancer. In the past three decades, survival of patients with primary BC have been notably improved, mainly due to early detection of the disease and advances in adjuvant treatments such as endocrine therapy, chemotherapy, and anti-HER2 therapy. Patients with HR-positive and HER2-negative primary BC account for approximately 70% of all cases of early breast cancer. Endocrine therapy is the core treatment for this subtype of BC. Tamoxifen, aromatase inhibitor or their sequential administration can reduce the recurrence and mortality of this BC subtype. The results of TEXT/SOFT study showed that, compared with the traditional 5-year tamoxifen treatment, tamoxifen + OFS or aromatase inhibitor + OFS can further improve the survival of HR+/HER2- breast cancer patients. However, for premenopausal BC patients with HR+/HER2-, only 82.5% (tamoxifen plus OFS) and 85.7% (aromatase inhibitor plus OFS) of 5-year DFS were achieved. For postmenopausal BC patients, the 5-year DFS was only about 84% with aromatase inhibitors. Therefore, the survival of HR+/ HER2- BC patients needs to be further improved. Metronomic chemotherapy refers to the use of the minimum effective dose of chemotherapy drugs for long-term, uninterrupted administration to achieve anti-tumor effect. Metronomic chemotherapy has gradually been verified in clinical practice in the past 20 years. In 2020, SYSUCC-001 study has confirmed that capecitabine (650 mg/ m2 bid, for 1 years) can reduce the risk of 5-year DFS events by 36% in TNBC patients in addition to standard treatment. Besides, POTENT study has confirmed that the combination of endocrine therapy and S-1 (for one year) can further reduce the risk of iDFS by 37% in HR+/HER2- BC patients who have completed the standard treatment. Compared with capecitabine, S-1 has no indication for BC and it is not in the recommendation for BC treatment in the guidelines. Therefore, the investigators conduct this study to explore whether adjuvant Capecitabine metronomic chemotherapy for one year can further improve the survival of BC patients with HR+/ HER2- in addition to standard treatment.
This study intends to prospectively enroll CNLC stage IIIb HCC cases with extrahepatic metastasis and intrahepatic lesions that are expected to be radical resected in several domestic clinical centers, and observe the OS and ORR, DCR, DOR, TTP and PFS of patients receiving hepatectomy combined with apatinib + carrelli pearl treatment.
Hypertension is a serious threat to human health and a major global economic burden. Chronic hypertension can cause left ventricular remodeling and loss of function, eventually leading to heart failure. Exploring the early changes and mechanisms of left ventricular cardiac function caused by hypertension, and to identify individuals who may develop into serious heart injury, may play a positive role in the early prevention and control of heart failure caused by hypertension. Therefore, this study intend to use two dimensional speckle tracking technology, a non-invasive method to measure left ventricular pressure-strain loop to quantitatively reflect cardiac work index , to study different hypertension patients with normal left ventricular ejection fraction the change of the global and local cardiac work, and the influence of aterosclerosis in the patients to myocardial work, and explore their relationship with ventricular remodeling and abnormal diastolic function. To improve the understanding of the pathophysiology of hypertension, hypertensive heart disease and heart failure, and to provide scientific support for the early prevention and control of such diseases. Myocardial work analysis Echocardiography plays a central role in the evaluation of patients with cardiovascular disease. Echocardiography is widely available and allows characterization of the functional and structural of heart. Thus, assessment of left lentricular (LV) global longitudinal strain (LVGLS) and Myocardial work indexes has proven benefit for both diagnosis and risk in hypertension patients.
This trial is a multi-center phase III clinical trial. The purpose of this trial is to explore whether concurrent chemoradiotherapy is not inferior to induction chemotherapy combined with concurrent chemoradiotherapy in patients with locally advanced nasopharyngeal carcinoma.
This randomized controlled clinical trial will estimate the eradication efficacy of different therapy for Helicobacter pylori treatment. The completion of this trial will expand new therapy for the treatment of Helicobacter pylori, which can not only ensure clinical efficacy, but also reduce the use of antibiotics.
Research Objectives: 1. Establish a prediction and scoring system for twin premature birth. 2.

This is an open-label, dose-escalation and dose-expansion phase I clinical study to evaluate the safety and tolerability of JS006 as Monotherapy and in combination with toripalimab in patients with advanced tumors who have failed standard therapies or who have no standard therapy. It is planned to enroll 69-176 patients into the study.
Our central hypothesis is that patient response to treatment, evaluated by full spectrum of outcome measures including tumor control, survival, toxicity, and quality of life (QoL), will correlate with biomarker expressions, which can be tested in the blood, other body fluid, imaging as well as tumor tissue (if available).
