Clinical trials

The goal of this clinical trial is to compare the efficacy and safety of induction Benmelstobart plus Anlotinib and chemotherapy followed by concurrent chemoradiotherapy (CCRT) and subsequent Benmelstobart maintenance versus CCRT followed by Benmelstobart maintenance in patients with unresectable stage III NSCLC. Additionally, high-throughput sequencing and multi-omics analysis will be performed on patient-derived tissue and blood samples. By integrating baseline characteristics with clinical data, we aim to identify key determinants of treatment efficacy and prognosis, thereby establishing a precision evaluation system for therapeutic outcomes.

The aim is to explore the reasons for the failure of assisted reproductive technology (ART) in infertile patients in Hunan Province and seek ways to improve the success rate of ART. The study will focus on how environmental exposure (such as environmental pollutants related to plastic products) and lifestyle and social factors affect the success rate of ART in infertile patients. In order to explore these issues in depth, the study plans to collect 5,000 samples (male: female ratio 1:1), screen the research subjects from infertile patients who visited Xiangya Third Hospital in Changsha, Hunan Province, and establish a large-scale, prospective infertility patient cohort. By collecting multi-faceted information of the research subjects, including sociodemographic characteristics, lifestyle, basic health status, etc., and conducting long-term follow-up observations, the ART live birth situation of infertile patients is analyzed. In terms of research methods, a multivariate analysis method will be used to explore the association between various factors and ART success rate, and a risk prediction model will be constructed. In addition, the study also hopes to clarify the specific reasons for the failure of infertile patients to receive ART, provide a scientific basis for clinical decision-making, and provide guidance for the formulation of environmental protection policies and the improvement of public reproductive health literacy. In general, this study, through a large-scale, prospective cohort study, deeply explores the various factors that affect the success rate of ART in infertile patients, and strives to build a risk prediction model in order to improve the success rate of ART and bring more hope to infertile families.

The research attempts to answer: for infertile women with uterine septum planning to undergo IVF/ICSI (excluding preimplantation genetic diagnosis), does TCRS improve pregnancy outcomes (such as live birth rate, pregnancy rate, miscarriage rate, etc.) compared to non-surgical treatment (conservative observation), and to clarify the clinical value and safety of this surgical intervention.

To evaluate the effect of uterine stents in preventing intrauterine adhesions after intrauterine operation and whether they meet the safety requirements for clinical use. The trial adopted a prospective, multicenter, randomized controlled, non-inferiority clinical trial design. The target population of the trial was 200 women aged 20-40 years with intrauterine adhesions and surgical indications (referring to those with fertility requirements or menstrual blood drainage obstruction), who were randomly divided into an experimental group and a control group, with 100 cases in each group. The experimental group was the group with intrauterine stents placed in the uterine cavity after hysteroscopic intrauterine adhesion separation surgery, and the control group was the group with intrauterine rings + balloons + sodium hyaluronate gel placed in the uterine cavity. After 3 courses of artificial cycles, the patients were hospitalized for hysteroscopy review.

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease characterized by the degeneration of motor neurons, leading to progressive muscle weakness and functional decline. This study is designed as a randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of an oral preparation of C. cicadae in patients with sporadic ALS and elevated plasma sphingolipid (SL) levels. Efficacy will be assessed primarily by changes in the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) score and plasma SL levels.Participants who meet the eligibility criteria and provide written informed consent will be randomly assigned in a 1:1 ratio to either the C. cicadae treatment group or the placebo group. The treatment group will receive oral C. cicadae at a dose of 0.1 g/kg/day (dry weight), administered in three divided doses per day. The placebo group will receive a matched placebo with a similar appearance and odor, administered according to the same schedule. A total of approximately 84 participants will be enrolled. The intervention period will be 6 months, and participants will be followed for a total of 9 months.

This large-scale study aims to understand how everyday environment and lifestyle may affect the success of fertility treatments like IVF. The main idea is that exposure to certain environmental chemicals (e.g., from plastics or air pollution) and personal habits (e.g., diet, stress) could be linked to whether these treatments result in a successful pregnancy and live birth. The study will follow approximately 5,000 couples undergoing fertility treatment in Hunan, China. Participants will answer questionnaires about their health, lifestyle, and environment and provide small biological samples (like blood and urine) during their standard treatment process. Their treatment outcomes will be tracked anonymously.The goal is to identify factors that might lower the chances of treatment success. This knowledge could help future patients and doctors make informed decisions and could guide public health advice on reducing potential risks. The study has received ethical approval, and all participant information will be kept strictly confidential.

Crohn's disease(CD) is a chronic nonspecific inflammatory disease of the intestinal tract whose etiology is not yet fully understood,characterized by transmural inflammation , can present with serious complications such as intestinal obstruction, perforation, abdominal abscesses, and fistulae. In recent years, the incidence of CD has increased rapidly, causing a heavy social and economic burden. Currently, the main therapeutic drugs for CD include aminosalicylic acid preparations, glucocorticoids, immunosuppressants, and biological agents. With the development of medical technology, small molecule preparations have begun to be applied to moderate-to-severe Crohn's disease, providing new treatment options for patients with Crohn's disease. Vedolizumab, a humanized monoclonal antibody.the GEMINI study demonstrated its superior efficacy over placebo in inducing and maintaining clinical remission. And the VERSIFY study confirmed its advantage in achieving mucosal healing, with a transmural healing rate of 29.1% at week 52. Intestinal ultrasound is a noninvasive, reproducible, convenient, and inexpensive test that can greatly increase the frequency of assessing treatment response and speed up the clinical decision-making process.The 2019 ECCO-ESGAR guidelines recommend intestinal ultrasound for disease monitoring in patients with CD. Multiple studies have shown that most ultrasound markers normalize within 12 weeks of treatment initiation, and in particular, normalization of bowel wall thickness is highly correlated with clinical response at 12 weeks. There are no validated indicators to predict the efficacy of upadacitinib treatment in patients with moderate-to-severe CD in the currently available studies. Currently, there are no national or international studies in which intestinal ultrasound predicts the efficacy and assesses the transmural healing of vedolizumab therapy. Therefore, we propose for the first time that intestinal ultrasound be used as a method to predict the response to vedolizumab in early CD patients, with the aim of providing evidence to guide the development of individualized treatment plans.

Crohn's disease (CD) is a chronic non-specific intestinal inflammatory disease with incompletely clarified etiology, which can involve multiple organs and systems , and is prone to severe complications such as intestinal obstruction, perforation, and fistula.Currently, the main therapeutic drugs for CD include aminosalicylates, glucocorticoids, immunosuppressants, biological agents, etc. With the development of medical technology, biological agents have begun to be applied to moderate-to-severe Crohn's disease, providing new treatment options for patients with moderate-to-severe Crohn's disease. Guselkumab is a selective inhibitor of the interleukin-23 (IL-23) p19 subunit.The GALAXI2 and GALAXI3 studies demonstrated that guselkumab can better achieve the therapeutic goal of mucosal healing. The clinical remission rates of guselkumab at week 12 were 47.1% and 47.1%, respectively, and the endoscopic response rates were 37.7% and 36.2%, respectively . Intestinal ultrasound lUsnoninvasive, reproducible, convenient, and inexpensive test that can greatly increase the frequency of assessing treatment response and speed up the clinical decision-making process.The 2019 ECCO-ESGAR guidelines recommend intestinalultrasound for disease monitoring in patients with CD. There are no validated indicators to predict the efficacy of guselkumab treatment in patients with moderate-to-severe CD in the currently available studies. Currently, there are no national orinternational studies in which intestinal ultrasound predicts the efficacy of guselkumab therapy. Therefore, we propose for the first time that intestinal ultrasound be used as a method to predict the response to guselkumab in CD patients, with the aiproviding evidence to guide the development of individualized treatment plans.
