OBJECTIVE: To explore the clinical characteristics and genetic basis of a child with Teebi hypertelorism syndrome 1 (TBHS1). METHODS: A child with TBHS1 who was admitted to the Children's Medical Center Affiliated to Shanghai Jiao Tong University School of Medicine on July 13, 2021 was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples of the child and his parents were collected and subjected to whole exome sequencing (WES). Candidate variant was verified by Sanger sequencing and bioinformatic analysis. RESULTS: The child, a 13-year-old male, had manifested delayed growth and development. WES results revealed that he has harbored a heterozygous c.1244A>G variant of the SPECC1L gene, which was verified to be de novo in origin. The variant has not been included in the HGMD and gnomAD databases. As predicted by online software including PolyPhen-2, SIFT, and Mutation Taster, the variant may affect the function of protein domain. And PyMOL software has predicted that the structural stability of SPECC1L protein (p.Gln415Arg) might be reduced. Based on the guidelines of the American College of Medical Genetics and Genomics (ACMG), the variant was classified as pathogenic (PM6+PM1+PP4+PM2_Supporting+PP3). CONCLUSION The heterozygous c.1244A>G variant of the SPECC1L gene probably underlay the TBHS1 in this child. Above finding has expanded the genotypic and phenotypic spectrum of the SPECC1L gene and provided a basis for the clinical diagnosis of this child.

Cardio-facio-cutaneous syndrome (CFCS) is a rare genetic syndrome associated with abnormal activation of RAS-mitogen-activated protein kinase(RAS-MAPK)signal transduction pathway.Causative genes are BRAF, MAP2K1, MAP2K2 and KRAS.CFCS is an autosomal dominant disorder characterized by dysmorphic craniofacial features, congenital heart disease, dermatologic abnormalities, gastrointestinal dysfunction, failure to thrive, neurocognitive delay and epilepsy, whose phenotype overlaps with many other RASopathies.Final diagnosis of CFCS can be reached by classical presentation and genetic testing.Early diagnosis helps to evaluate risk of severe complications of specific genotype and improve prognosis of CFCS patients.At present, there is no effective treatment of CFCS although inhibitors of MEK may improve partial phenotype of CFCS animal models.Once diagnosed with CFCS, the patients need multidisciplinary assessment and treatment.

By comparing the training status of clinical research methods between United States and China, this article introduces comprehensive training system in the United States in and after the university, and discusses the problems in clinical research methodology training in China. These issues include that when medical students at school do not receive the training of professional clinical research courses, and after they go to the work, they also lack professional and accurate clinical research methodology training, which make it difficult for doctors to independently conduct clinical research. Therefore, it is recommended that Chinese medical schools should systematically establish clinical research methodology courses for undergraduates and graduate students to cultivate the clinical research capabilities of medical students. Secondly, according to the clinical research levels of doctors, different training models are proposed in the study. The existing social resources should be scientifically guided. We hope our work would provide some references for the improvement of clinical research methodology in China, to promote clinicians to be independently responsible for conducting clinical research, and improve the national medical level.

Effective supervision of the clinical research management department can guarantee and improve the quality of the investigator initiated trials(IIT). The authors analyzed relevant clinical research regulations and literature and summarized the current situation of risk-based IIT project process quality management. On such basis, they determined the risk-based IIT project process quality management method in combination with the previous research of the research group.From 2021 to 2022, this method was used to implement process quality management for 353 IIT projects in Shanghai′s tertiary hospitals. More than 3 000 risk points were identified through centralized supervision, and then on-site supervision was carried out to correct the problems found. As proven by the results, the method could find existing problems in time and define the risk level of the project, and also formulate an individualized risk supervision plan accordingly, so as to effectively ensure the data reliability and scientific results. It is suggested that the clinical research management department implement risk based management for the whole process of IIT projects, increase funding and staffing, and implement hierarchical management for the projects by research types, so as to promote the sustainable development of IITs.

Congenital disorders of glycosylation(CDG)are a group of rare inherited metabolic diseases due to defects in the glycosylation of glycoproteins and/or glycolipids.Most of them are autosomal recessive and have multisystemic manifestations, which is characterized by dysmorphic facial features, developmental delay, growth failure, hypotonia, neurological abnormalities, hypoglycemia and multisystem disfunctions.Isoelectrofocusing(IEF)analysis of transferrin(Tf)and mass spectrometry(MS)technology can diagnose some subtypes of CDG, while many currently rely on genomic sequencing technology for diagnosis.A few subtypes can be clinically relieved or even cured by treatment, but most have no effective treatment.Development of molecular, biochemical and facial recognition techniques may deepen our understanding of this disease.

Objective:Investigator Initiated Trials (IIT) play a key role in promoting comprehensively the development and homogeneity of clinical diagnosis and treatment, thus, this article aims to explore a set of recommendations for the construction and management of clinical research institutes that support IIT.Methods:Through the combination of literature review and institutional construction practice cases, based on the experience of domestic and foreign universities and well-functioning medical institutions in building clinical research centers, as well as summarizing the construction cases of the clinical research institute of Shanghai Jiao Tong University School of Medicine, to discuss the construction and management plan of such centers.Results:Propose recommendations for the construction and management standards of clinical research centers that support IIT, covering the principles of center construction, basic settings, organizational structure, functional departments, basic platforms, staffing, document management and institutional evaluation.Conclusions:We hope this study can provide reference to universities and medical institutions for the construction of the clinical research institute.

Objective:To explore the current status and correlation of physical activity and exercise ability in patients after coronary heart disease surgery.Methods:A retrospective research method was used to analyze the case data of 230 postoperative coronary heart disease patients who were admitted to the Heart Rehabilitation Center of a Class Ⅲ Grade A cardiovascular disease hospital in Beijing from January to October 2019. The International Physical Activity Questionnaire-Short (IPAQ-S) was used to measure physical activity, and the Cardiopulmonary Exercise Testing was used to measure exercise ability.Results:A total of 85.2% (196/230) of patients with coronary heart disease were in low-medium level of physical activity, and 97.0% (223/230) of patients had reduced exercise ability. The binary Logistic regression showed that age, medical insurance type, smoking history and peak loqd were the influencing factors of physical activity in patients after coronary heart disease surgery ( P<0.05) . Conclusions:Most patients after coronary heart disease have insufficient physical activity and reduced exercise ability. Medical and nursing staff should focus on physical activity health education for patients with older age, medical insurance outside Beijing, and a history of smoking, and formulate scientific and personalized physical activity intervention measures. There is a positive correlation between the level of physical activity and exercise ability. Increasing the exercise ability of patients after coronary heart disease surgery is of great significance for improving the level of physical activity.
