This clinical trial aim to evaluate the efficacy and safety of Pyrotinib in combination with nab-paclitaxel in patients with HER2-positive advanced breast cancer.
to determine the most suitable time for administration of (human chorionic gonadotropin )hCG prior to intrauterine insemination (IUI) to optimize pregnancy outcome and to have the best success rates so the cases divided in to four groups according to the time of hCG administration .
This study aims to evaluate the predictive value of a four-gene methylation assay called Guangzhou Panel in early-stage colorectal cancer. Patients will be divided into two groups: high risk group and low risk group. The primary endpoint is 5 year disease free survival (DFS).
To evaluate the effect of systemic administration of zinc on the gingival crevicular fluid level of total oxidant capacity in controlled Type-2 diabetic patients with stage-II and III periodontitis after non-surgical periodontal therapy.
Introduction: Knee osteoarthritis (KOA) is the most prevalent joint condition and is characterized by the progressive erosion of the articular cartilage. In TCM, Pulse Diagnosis has been one of the key diagnostic components in the clinical examinations. Modern pulse diagnosis studies have found that when the human body develops disease or is under pressure, the high frequency spectral energy (10-50Hz) will significantly change. Augmentation index (AIx) is related to the wave reflection of blood vessels. AIx can function as a useful index to reveal aging blood vessels. The experiment will use spectral energy and AIx as objective judgments about the efficacy of before-acupuncture and after-acupuncture treatment. Method: This randomized controlled study will recruit 120 participants which will be allocated to 3 groups: Distal Acupoints, Proximal Acupoints and Sham Acupoints. Each group will have 40 participants to ensure a sufficient sample size can be attained for statistical analysis. Participants aged 20 or older with acute or chronic arthritis will be recruited when they meet the Clinical Classification Criteria for KOA, that is knee pain and three out of six symptoms can be found in clinical practices, as recommended by the American College of Rheumatology:(a) any gender aged 50 years or above;(b) have less than 30 mins of morning stiffness ; (c) crepitus on active motion; and (d)bony tenderness;(e)bony enlargement; and (f)no palpable warmth.Objective and subjective baseline assessments and outcome evaluations including VAS, The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and range of knee motion will be performed. The primary outcome will be the assessment of Spectral Energy and AIx of radial pressure pulse-wave in both wrists (Chun, Guan, and Chy pulse) using the Pulse Sphygmograph before and after the intervention. The secondary outcome involves evaluating VAS and range of knee motion. Expected Outcome: The research findings can be clinical evidence regarding the effect of acupuncture KOA on radial artery. Moreover, the research will explore the immediate-effect difference between distal and proximal acupoints on KOA.
The goal of this prospective observational study is to investigate minimum cuff pressure to prevent gas leakage during mechanical ventilation in laryngomicrosurgery.
Skeletal muscle regenerates after injury, due to the satellite cells (SCs), the muscle stem cells that activate, proliferate, differentiate and fuse to form new myofibers. While SCs are indispensable for regeneration, there is increasing evidence for the need for an adequate cellular environment. Among the closest cellular partners of SCs are vascular cells. During muscle regeneration, endothelial cells (ECs) stimulate SC differentiation while SCs exhibit pro-angiogenic properties indicating a coupling between angiogenesis and myogenesis.The specific signaling cues controlling these relationships are still poorly characterized, specially in specific pathologic context such as limb ischemia. The investigators research aims to evaluate the role of chronic and acute lower limb ischemia on the SC status and interaction with ECs in human patients.
the aim of the present study is to Compare Safety and Efficacy of Vaginal dinoprostone Versus Lidocaine-prilocaine Cream in copper IUD Insertion in nulliparous women: a randomized controlled trial
This is a multicenter, double-blind randomized controlled study to assess the efficacy and safety of Jinshuibao for patients with CKD due to glomerulonephritis, with a planned follow-up of 48 weeks.
Rheumatoid arthritis (RA) is a condition associated with a high incidence of cardiovascular disease (CV), primarily as a result of accelerated atherosclerosis . Patients with RA also have a high prevalence of metabolic syndrome (MS) The state of chronic inflammation in RA patients contributes to increased CV risk. Deregulation of both genetic and serological adipocines, MS biomarkers, and biomarkers of endothelial activation and inflammation also contributes to the increased CV risk in these patients. An increased incidence of abnormal carotid intima-media thickness (cIMT) values and carotid plaques, considered surrogate markers of subclinical atherosclerotic disease, has also been described in patients with RA. Positron emission tomography/computed tomography (PET/CT) is a noninvasive imaging technique useful for the evaluation of inflammation (by 18F-FDG uptake) and mineralization (by 18F-NaF uptake) in carotid atheroma plaque. Atherosclerosis and RA share many common inflammatory pathways, and the mechanisms that lead to synovial inflammation are similar to those seen in atherosclerotic plaque. Interleukin (IL)-6 is a key pro-inflammatory cytokine involved in both the pathophysiology of RA and the development of atherosclerosis. Sarilumab is a human monoclonal antibody against the IL-6 receptor that has been shown to be effective in patients with RA, improving symptoms, as well as at the functional and radiographic levels. Treatment with IL-6 receptor inhibitors has been described to result in a modulation of lipid metabolism, mediated by a reduction in lipoprotein (a) (Lp(a)) and an improvement in the anti-oxidant function of high-density lipoprotein (HDL) . In this regard, Sarilumab may have beneficial effects in RA patients on MS, which is implicated in the development of atherosclerotic disease. Information regarding the beneficial effect of IL-6 receptor blockade on atheroma plaque formation and its effect at the vascular level in RA patients is scarce.
