To further promote the expansion of new clinical technologies and surgical methods, and to improve surgical efficacy, the Refractive Surgery Experts Group of Ocular Microcirculation Branch of Chinese Society of Microcirculation, according to the latest domestic and foreign research results, has recently updated the consensus after a collective discussion.

22q11.2 deletion syndrome (22q11.2DS) is the most common chromosomal microdeletion disorder. Its phenotype is highly variable with incomplete penetrance. 22q11.2DS is a rare disease, and the research progress is relatively slow, which has restricted its treatment and intervention. In recent years, much progress has been made in the pathogenic mechanism and genome-wide association study of 22q11.2DS. In this review, the pathogenesis of 22q11.2DS was summarized. Thereafter, the molecular and pathological mechanisms of TBX1 and DGCR8 genes were clarified. Finally, factors affecting the penetrance of cardiac and immune system phenotypes were reviewed. This review may enhance the understanding of 22q11.2DS and has important clinical implications on the prenatal diagnosis, genetic counseling, treatment and intervention of this disease.

Congenital joint synostosis (CJS) is a functional impairment resulting from failure in joint morphogenesis during embryonic development. Clinically, it may be classified as syndromic (sCJS) and non-syndromic (nsCJS) disorders. Common sCJS include chromosomal disorders such as Klinefelter syndrome and single-gene disorders like Apert/Pfeiffer/Crouzon syndromes, Holt-Oram syndrome, Ehlers-Danlos syndrome, and Radial-ulnar synostosis with thrombocytopenia, presenting with multiple system/organ anomalies. By contrast, nsCJS manifest with only joint abnormalities, affecting one or multiple joints. This review has focused on human nsCJS and its genetic etiology. To date, variants in seven genes (NOG, GDF5, FGF9, GDF6, FGF16, SMAD6, and MECOM) have been identified as causative factors for nsCJS. This review has focused on such genes and provided a comprehensive review for the clinical phenotypes, genetic patterns, common variants, and underlying mechanisms associated with nsCJS based on a literature review. In addition, it has also analyzed other candidate genes for nsCJS within the context of relevant signaling pathways involved in joint morphogenesis.

DNA methylation is an important epigenetic regulatory mechanism which plays a crucial role in cell differentiation and development. Its function is closely related to DNA methyltransferase 3 alpha (DNMT3A), which can affect gene expression and stem cell differentiation. The mutation rate of the DNMT3A gene is relatively high in Acute myeloid leukemia (AML), but its type and pathogenic mechanism are not yet clear. Further research on DNMT3A may help to identify its pathogenic targets and provide a basis for precise treatment of AML. This article has provided a review for the research progress on the expression of the DNMT3A gene in AML.

ABSTRACT Purpose The study seeks to address the influence of different facets of business-to-business (B2B) relationship marketing on internationalization effectiveness, by taking into account the turbulent environment generated by the COVID-19 pandemic. The focus falls on the factors that generate, frame, catalyze, sustain and strengthen international business relationships between managers from organizations with converging interests. Methodology B2B relationship marketing in the international arena is analyzed by means of various angles such as business convergence, business context, interpersonal compatibility, business credibility and network interconnections as availed by the “new normal” triggered by the COVID-19 pandemic. A questionnaire-based survey with 158 business owners and managers from European industrial companies was carried out during November 2023 to investigate the configuration and dynamics of B2B relationship marketing in the unprecedented and systemic COVID-19 crisis. Data was analyzed via structural equation modeling using SmartPLS 4. Findings The findings showed that while business convergence remains a strong influencer of all the other relational dimensions, the restrictions and limitations engendered by the pandemic have also altered international B2B relationship marketing to such an extent that the only significant factor for internationalization effectiveness relies on business networking. Research and practical implications The study has both theoretical and practical implications, bringing forward a topical perspective on international B2B relationships during COVID-19 disruptions and their impact on the effectiveness of international operations. Originality The study advances a phenomenological view of the unprecedented changes and their influences on the overseas operations of SMEs in a particular field. It complements and adds to the literature by stressing a more articulated relationship-centric architecture, which probed relevance during the pandemic.

Pneumonia is one of the most common severe infectious diseases in pediatric practice. Hypoxia is common in children with pneumonia and is one of the main predictors of poor outcome. The role of the central link in the cellular response to hypoxia is played by the family of hypoxia-inducible factors (HIF). HIF-1α is the key regulator of both T- and B-lymphocyte functions. The processes of their maturation are accompanied by the formation of circular DNA fragments, TREC (T-cell Receptor Excision Circle) and KREC (Kappa-deleting Recombination Excision Circle). TREC and KREC are unable to replicate and serve as markers for naive lymphocyte production. In its turn, HIF-1α can be used as a marker for cellular hypoxia. The use of TREC and KREC in assessing the immune system in patients with various immunological and infectious pathologies has already been described. At the same time, HIF-1α has so far been little studied as yet. The purpose of this research was to analyze the scientific bibliographical data on the HIF-1α assessment as a marker for hypoxia as well as the quantitative level of TREC and KREC as markers for the adaptive immune response; to study the bibliographical sources on the effect of hypoxia on the immune response, including as part of lower respiratory tract infections. Methods used: bibliographical research in Scopus, PubMed and Google Scholar with keywords “TREC,” “KREC,” “HIF,” “hypoxia,” “pneumonia,” “immune response,” that was then followed by the search results’ systematization, analysis and synthesis. Results: the analysis of bibliographical sources had allowed the Authors to conclude that there is a possible close connection between acute hypoxia and the formation of an adequate immune response in infectious pathologies. Research in this area is still extremely scarce. At the same time, the prospects for this area determine the need for further fundamental and clinical research. Conclusion: it is of a great scientific and clinical interest to be able to non-invasively assess the degree of acute hypoxia during an ongoing infectious disease by examining urinary HIF-1α levels. Particularly promising is the assessment of the HIF-1α level not only as a regulator of tissue adaptation to acute hypoxia, but also as a modulator of the immune response. Taking into consideration the analyzed data, both TREC and KREC appear to be the optimal markers characterizing the functional state of the adaptive immune system.
