This invention relates to the interdisciplinary field of assisted reproductive technology and artificial intelligence, specifically to a system and method for constructing an embryonic developmental trajectory map that integrates morphological features. By deeply integrating static morphological features with dynamic morphodynamic parameters, a more comprehensive panoramic map of embryonic development with richer information dimensions is constructed, overcoming the one-sidedness of single-dimensional assessment. Automated analysis of the map using an AI model reduces the influence of subjective human factors, enabling the discovery of subtle developmental patterns and potential differences that are difficult to discern with the human eye, significantly improving the accuracy of selecting high-quality embryos. The provided developmental trajectory map allows embryologists to intuitively examine the entire developmental process of the embryo and the performance of each key node, enhancing the interpretability and credibility of the assessment process. Through more scientific embryo selection, it is expected to improve embryo implantation and clinical pregnancy rates, and reduce multiple pregnancy and miscarriage rates.

The invention discloses a high-strength self-lubricating three-layer nested medicine-carrying hollow cervical cerclage band with an auxiliary miscarriage prevention function and a preparation method of the cerclage band, and belongs to the technical field of medical instruments. Degradable polyester monofilaments are woven into a hollow round rope, and the hollow round rope and a medical curved needle are integrated; then carrying out polydopamine-polyethylene glycol double-layer modification on a copper-based metal organic framework (Cu-MOF), and loading active molecules; then mixing the drug-loaded Cu-MOF with collagen natural polymer sol, and uniformly filling the gel into the inner cavity of the round rope and forming a three-dimensional bracket through synchronous drawing type micro-perfusion and light-enzyme synergistic cross-linking; then constructing a transient hydrated lubricating layer on the surface; and finally carrying out ethylene oxide final sterilization to obtain a finished product. The cervical cerclage band device provided by the invention simultaneously provides degradable mechanical support, collagen scaffold induction and long-acting slow release regulation, has a low-friction implantation characteristic, and can be well used for preventing or treating middle and late abortion and premature delivery caused by cervical insufficiency.

The invention relates to methods for assessing the risk of miscarriage or embryo implantation failure, and also for monitoring or evaluating the effect of a treatment to reduce the risk of miscarriage or embryo implantation failure using specific biomarkers. The invention also relates to the use of these biomarkers in methods of diagnosing a reproductive disorder in an individual, and also to methods of treating a reproductive disorder. In addition, the biomarkers can further be used in methods of selecting patients for treatment to reduce risk of embryo implantation failure or miscarriage. The invention also relates to kits for use in any of the methods described herein.

The invention relates to the technical field of biological medicine, in particular to application of TRIM21 serving as a biomarker in screening or preparing a preparation for reducing ciprofloxacin exposure related abortion risk. The problems that in the prior art, key action links and molecular mechanisms of pregnancy loss caused by exposure of environment or non-therapeutic dose ciprofloxacin are not clear, and objective detection markers capable of prompting risk states in the early stage of pregnancy and relatively standard and repeatable detection methods are lacked are solved. The invention discloses an application of TRIM21 as a biomarker in screening or preparing a preparation for reducing miscarriage risk related to ciprofloxacin exposure, the pregnancy risk caused by ciprofloxacin exposure can be recognized in an early stage by detecting the expression level of TRIM21, and a candidate preparation with a protective effect is further screened. The invention provides a new thought and target for developing a novel medicine for preventing abortion.

The invention belongs to the technical field of traditional Chinese medicine compositions, and particularly relates to a traditional Chinese medicine composition for treating repeated planting failure and a preparation method and application thereof. The traditional Chinese medicine composition disclosed by the invention has the effects of removing blood stasis, tonifying kidney and warming meridians by promoting blood circulation, removing blood stasis and tonifying kidney; furthermore, the uterus-warming and kidney-tonifying treatment traditional Chinese medicine composition is used for warming meridians and uterus, tonifying kidney and nourishing blood to improve the intimal receptivity; further, the post-transplantation implantation miscarriage prevention treatment traditional Chinese medicine composition is used for achieving the effects of strengthening heart, assisting embryo, nourishing blood, preventing miscarriage and supporting early pregnancy; the three groups of traditional Chinese medicine components are subjected to progressive three-stage treatment to realize systematic intervention from eliminating evil to strengthening the body resistance and then to miscarriage prevention, so that the embryo implantation rate and the clinical pregnancy rate of a patient with repeated implantation failure are improved.

The present disclosure relates to a composition for treating infertility, which includes beta core fragment hCG (βcf hCG) as an active ingredient. The βcf hCG is identified to stimulate endometrial development in early pregnancy, is highly expressed in placental tissue, and is involved in maintaining fetal development in early pregnancy. The composition plays an important role in implantation and maintenance of early pregnancy by increasing the thickness of the endometrium, increasing the expression of genes necessary for uterine development, and promoting the growth of uterine-derived cell line. The composition can be usefully used to treat habitual miscarriage in female infertility, and to increase the success rate of pregnancy by improving the implantation rate of fertilized eggs in the process of in vitro fertilization.

The invention belongs to the technical field of traditional Chinese medicines, and particularly relates to a traditional Chinese medicine composition for preventing or treating early abortion of polycystic ovarian syndrome as well as a preparation method and application thereof. The traditional Chinese medicine composition is prepared from glossy privet fruit, morinda officinalis, radix rehmanniae preparata, astragalus membranaceus, codonopsis pilosula, Chinese yam, rhizoma atractylodis, radix ophiopogonis, rhizoma anemarrhenae and coptis chinensis, has the effects of tonifying kidney and spleen, clearing heat and drying dampness and harmonizing chong and ren channels, and is mainly used for preventing or treating early abortion of polycystic ovarian syndrome. The traditional Chinese medicine composition disclosed by the invention has a synergistic effect in the aspect of treating early abortion caused by the polycystic ovarian syndrome, systematically deals with complex endocrine metabolism disorder of a patient with the polycystic ovarian syndrome, and provides a brand new treatment strategy for miscarriage prevention. Meanwhile, the novel application of the traditional Chinese medicine composition in preparation of medicines for preventing and treating early abortion of polycystic ovarian syndrome is defined. Therefore, the traditional Chinese medicine composition has important clinical significance and wide market application prospects.
