Oocyte maturation disorders and fertilization failures are caused by a variety of factors, including complex factors such as chromosomal abnormalities and poor oocyte quality. With the widespread use of high-throughput sequencing technology, more and more genetic mutations have been found to be associated with oocyte maturation and fertilization process in infertile patients. This paper summarizes and discusses 11 key genes ( TRIP13, TBPL2, LHX8, PATL2, TUBB8, CDC20, WEE2, ZP, ASTL, JUNO and CD9) related to oocyte maturation and fertilization-related disorders in females, providing a basis for research on the prevention of diseases associated with oocyte maturation blockage and fertilization failure and the development of targeted therapies.

Non-classical congenital adrenal hyperplasia (NCCAH), an autosomal recessive disorder, stems from genetic mutations affecting the enzymes and cofactors integral to adrenal steroidogenesis. These mutations may result in diminished activity or a complete loss of function for critical enzymes, such as 21-hydroxylase, 11β-hydroxylase, 3β-hydroxysteroid dehydrogenase, 17α-hydroxylase, and the steroidogenic acute regulatory protein (StAR). The impairment of these enzymatic processes has profound implications for reproductive health in females, mediated through both genetic and endocrine pathways. This review aims to explore the pathogenesis of various enzyme defects in different types of NCCAH, their clinical features, and their impact on female fertility. It is hoped that this will help refine the diagnostic strategies for infertility associated with NCCAH, thereby enhancing fertility of patients and providing new directions and opportunities for further research in this field.

To summarize the nursing experience of a patient with coronary heart disease who was left in the radial artery during the removal of the radial artery sheath after coronary angiography via the radial artery pathway.Nursing points:to start the emergency transfer process,to shorten the treatment transfer time;to assist to locate the position of the sheath to provide a basis for the selection of surgical incision;to conduct dynamic assessment of hemostatic effect,prevention of radial artery occlusion;to closely monitor pain and signs to prevent vasovagal reflex;to implement the whole psychological intervention,and to reduce the psychological burden of patients and their families.The ruptured sheath tube was successfully removed by emergency surgery of vascular surgery.A total of 6 days after the operation,the patient was transferred to cardiac surgery for coronary artery bypass grafting,and was discharged 23 days later.After 3 months of follow-up,the blood supply of the limbs was good,and the incision healed well.

The proposal of new quality productive forces provide the key driving force and strategy for the high-quality de-velopment of public hospitals and the acceleration of health modernization.In the era of promoting high-quality development with new quality productive forces,large public hospitals,as the main force to promote the development of China's health cause,ex-plore the path of international innovation and development has become its important mission.This paper summarizes experience of The First Affiliated Hospital,Sun Yat-sen University on how to promote discipline construction,scientific innovation,talent train-ing,brand construction,etc.,through international exchange and cooperation.The authors put forward suggestions for public hospitals on cultivating new quality productive forces,aiming to provide reference for empowering high-quality development through international exchange and cooperation while facing new challenges.

To research and design a new type of distal radial artery puncture compression hemostatic device,to solve the problem of distal radial artery puncture and compression hemostat that has not been clinically applied in China.The hemostatic device was mainly composed of hemostatic part,pressure regulating part,fixing part and visual window.The hemostatic device can accurately compress the puncture point,and it was convenient for medical staff to observe the wound through the visual window,find out abnormal conditions such as bleeding or hematoma in time,and take measures to deal with them,which greatly improved the hemostatic effect and comfort of the postoperative puncture point.The new hemostatic device has the advantages of reasonable design and simple clinical operation,which is worthy of clinical promotion.

Objective:Peritoneal free cancer cells can negatively impact disease progression and patient outcomes in gastric cancer.This study aimed to investigate the feasibility of using golden-angle radial sampling dynamic contrast-enhanced magnetic resonance imaging(GRASP DCE-MRI)to predict the presence of peritoneal free cancer cells in gastric cancer patients.Methods:All enrolled patients were consecutively divided into analysis and validation groups.Preoperative magnetic resonance imaging(MRI)scans and perfusion were performed in patients with gastric cancer undergoing surgery,and peritoneal lavage specimens were collected for examination.Based on the peritoneal lavage cytology(PLC)results,patients were divided into negative and positive lavage fluid groups.The data collected included clinical and MR information.A nomogram prediction model was constructed to predict the positive rate of peritoneal lavage fluid,and the validity of the model was verified based on data from the verification group.Results:There was no statistical difference between the proportion of PLC-positive cases predicted by GRASP DCE-MR and the actual PLC test.MR tumor stage,tumor thickness,and perfusion parameter Tofts-Ketty model volume transfer constant(Ktrans)were independent predictors of positive peritoneal lavage fluid.The nomogram model featured a concordance index(C-index)of 0.785 and 0.742 for the modeling and validation groups,respectively.Conclusions:GRASP DCE-MR could effectively predict peritoneal free cancer cells in gastric cancer patients.The nomogram model constructed using these predictors may help clinicians to better predict the risk of peritoneal free cancer cells being present in gastric cancer patients.

Literature related to children's adenoid hypertrophy was retrieved to form an expert questionnaire.According to the group standard writing rules of the China Association of Chinese Medicine,the peer consultation,quality evaluation and suitability eval-uation were completed through three rounds of Delphi expert questionnaire surveys and expert discussion meetings,and the Clinical Practice Guidelines for TCM in Children with Adenoidal Hypertrophy was finally formed.The guidelines have been formulated to clarify the scope of application of the guidelines,normative reference documents,terms and definitions,diagnosis,syndrome differentiation,treatment,prevention and care,and to provide an important reference for the clinical practice and diagnosis and treatment norms of tra-ditional Chinese medicine for children with adenoid hypertrophy.
