Precancerous lesions of gastric cancer （PLGC） are a group of pathological changes caused by abnormalities in the structure， morphology， and differentiation of gastric mucosal epithelial cells. Since the early symptoms are hidden and non-specific， PLGC is not easy to be diagnosed and it has often developed into intermediate or advanced gastric cancer once being diagnosed and missed the best time for treatment. Accordingly， the incidence of this disease is increasing year by year， which lifts a heavy burden on the patients. The pathogenesis of PLGC is complex， involving inflammatory microenvironment， bile reflux， glycolysis， autophagy， and apoptosis. Currently， PLGC is mainly treated with anti-inflammatory and endoscopic therapies， which are difficult to curb the development of PLGC. Therefore， seeking a safe and effective therapy is an important topic of modern research. Traditional Chinese medicine （TCM）， characterized by treatment based on syndrome differentiation and a holistic view， exerts effects via multiple pathways， mechanisms， and targets. Recent studies have confirmed that TCM can regulate the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR）， Wnt/β-catenin， Sonic Hedgehog， nuclear factor-κB （NF-κB）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， hypoxia-inducible factor-1α （HIF-1α）， neurogenic locus notch homolog protein （Notch）， nuclear factor E₂-related factor 2 （Nrf2） and other signaling pathways. By targeting these pathways， TCM can inhibit aerobic glycolysis， reduce oxidative stress， repair the inflammatory microenvironment， regulate cellular autophagy， and promote vascular normalization， thereby delaying or reversing PLGC. However， few researchers have systematically summarized the TCM regulation of PLGC-associated pathways. By reviewing the relevant articles at home and abroad， this paper summarized the roles of the above signaling pathways in the development of PLGC and the research progress in the regulation of signaling pathways by TCM in the treatment of PLGC， with a view to providing a new theoretical basis for the clinical research on PLGC and the drug development for this disease.

The ethics review approval criteria are the basis for ethical review committees to make review decisions. A thorough understanding of the requirements of the ethics review approval criteria is a prerequisite for ensuring the quality of ethical reviews. The Measures for the Ethics Review of Life Science and Medical Research Involving Humans made significant adjustments to the ethics review approval criteria， such as new provisions regarding the qualifications of researchers and research institutions， and the release of research results. In combination with the 2024 edition of the Declaration of Helsinki， this paper analyzed the requirements of the Measures for ethics review approval criteria， as well as explored the corresponding ethical principles and corresponding ethical review key points， with a view to providing a reference for standardizing ethics review practice and effectively improving the quality of ethics review.

Objective To compare the clinical efficacy of resecting epiglottic cysts using low-tem-perature plasma scalpel versus ultrasonic scalpel under suspension laryngoscopy.Methods A total of 120 patients with epiglottic cysts were selected and divided into plasma group and ultrasonic scalpel group,with 60 cases in each group.The plasma group underwent resection of epiglottic cysts with low-temperature plasma scalpel under suspension laryngoscopy,while the ultrasonic scalpel group was trea-ted with ultrasonic scalpel under suspension laryngoscopy.The operation time,the time from postoper-ation to complete wound healing,and the amount of bleeding during treatment were recorded.Pain levels at 1,3,and 5 d after treatment,as well as the effectiveness of treatment and complication rates one month later were compared between the two groups.Results The operation time and blood loss in the plasma group were lower or shorter than those in the ultrasonic scalpel group(P＜0.05).The wound healing time in the plasma group was shorter,postoperative pain was less,and the incidence of complications was lower in the ultrasonic scalpel group compared to the ultrasonic scalpel group(P＜0.05).Conclusion Under suspension laryngoscopy,the low-temperature plasma scalpel is more ef-fective in treating epiglottic cysts than the ultrasonic scalpel,which can shorten operation time and re-duce blood loss,alleviate pain,and decrease the rate of complications.

The cognition and attitude of scientific research ethics consciousness affect the willingness and degree of individual researchers to follow research ethics norms. This study investigated the awareness, access and training needs of Chinese medical researchers (n=11 164) on the knowledge of scientific research ethics. The survey found that more than 50.0% of people were aware of the "golden rice incident" and "skull transplantation"; 80.0% of people were knew of Operational Quideline for the Ethic Review of Biomedical Research Involving Human Subject; 90.0% said that "respecting people" and "not harming" were the basic ethical principles, but 42.8% and 75.1% chose "beneficial" and "fair" respectively; more than 60.0% of people have acquired scientific research ethics knowledge through "self-study", "special training organized by units" or "words and deeds taught by mentors or colleagues", but still 30.0% have not participated in scientific research ethics lectures in recent three years; In terms of training needs, more than 50.0% chose "ethical norms for research and application", followed by "frontier ethical issues" (41.0%) and "ethical review" (36.7%). Based on this, this paper puts forward some suggestions to improve the content and form of scientific research ethics education and training in China.

For multi-center clinical research, how to ensure the quality of ethical review and improve the efficiency of ethical review through cooperation among centers is an important direction for clinical research management departments and research parties to explore. By combing and analyzing the existing pattern of multi-center ethical review at home and abroad, combining the current situation of the ethical review and management development in China, taking cancer clinical research as the breakthrough point, it was advocated to establish a cooperative review led by professional institute in domestic, on the basis of extensive and in-depth training exchanges and effective communication on the same platform, collaborative review, ensure quality and efficiency, so as to promote and implement the "mutual recognition" of ethical review. Then, this paper further put forward the concept of "whole-process linkage" in the ethical management process of multi-center clinical research, and pointed out that all research parties should clarify their responsibilities, enhance their awareness and ability, and jointly and comprehensively implement the protection of subjects among clinical researchers.

Gastric cancer （GC） is one of the most common cancers in the world， with hidden symptoms， complex pathogenesis， high morbidity， high mortality， and poor prognosis. As one of the classical apoptosis pathways， mitochondrial apoptosis has been widely described in the apoptosis escape by GC cells. Mitochondrial apoptosis can regulate the proliferation， invasion， and metastasis of GC cells via oxidative stress， cell cycle， mitochondrial membrane potential， mitochondrial translocation and other mechanisms， and it is one of the potential targets of traditional Chinese medicine （TCM） intervention to restore the mitochondrial function in GC. The theory of spleen-mitochondria in correlation explains that spleen deficiency and cancer toxin are the root causes of mitochondrial apoptosis. Accordingly， the TCM treatment should follow the basic principle of invigorating spleen to restore healthy Qi and removing cancer toxin to eliminate the root cause. Mitochondrial apoptosis can be promoted by inhibiting oxidative stress， promoting cell cycle arrest， and reducing mitochondrial membrane potential. This therapy can improve the energy metabolism， restore the mitochondrial structure and function， and prevent the occurrence and development of GC， with mild side effects and low drug resistance. However， the mechanism of mitochondrial apoptosis in GC and the target of TCM intervention in GC have not been systematically reviewed. Therefore， this paper systematically summarized the effects of mitochondrial apoptosis on the occurrence and development of GC and the role of TCM in the treatment of GC by intervening in mitochondrial apoptosis， aiming to provide a theoretical reference for the treatment and further research of GC.

With the intensification of aging society,more and more patients are troubled by low back pain,which brings burden to patients and society. Intervertebral disc degeneration (IVDD) is the main cause of chronic low back pain. Clarifying the pathogenic mechanism of IVDD is of great significance to solve the current health problems. In recent years,there have been a lot of reports on the role of the Sonic Hedgehog (Shh) pathway in IVDD. Shh signaling pathway plays an important role in the formation and postnatal maintenance of intervertebral disc,and the expression change of this pathway is accompanied by age-related degenerative changes of intervertebral disc. Targeting the Shh signaling pathway may have important implications in IVDD treatment. This review summarizes the research progress of Shh signaling pathway in IVDD,attempts to explore the possible relationship between this signaling pathway and various known pathologies of IVDD,and looks forward to future research content,in order to provide reference for exploring effective treatment and prevention methods of IVDD.
