Precision medicine is a medical paradigm founded on individual genetic information amalgamated with extensive clinical data to offer patients precise diagnoses and treatments. Genetic testing forms the cornerstone of accurate diagnosis, and skilled professionals in fields like clinical medicine, molecular biology, and bioinformatics play a crucial role in realizing the potential of precision medicine. This paper presents reference suggestions for the continuing education approach for relevant technical personnel. The main emphasis is on conducting routine face-to-face and hands-on training to enhance theoretical knowledge and professional skills. Secondly, there is a need to modify the training approach by reinforcing molecular biology, bioinformatics, and other courses, enhancing assessment methods, gradually implementing specialized training in precision medicine subspecialties, and ensuring effective clinical practice and management of precision medicine.
Heritable aortic disease (HAD) is characterized by thoracic aortic aneurysm/dissection with strong genetic predisposition and high clinical phenotypic heterogeneity. HAD is one of the main causes of sudden death. Early diagnosis of this disease is difficult because of atypical clinical symptoms, leading to the deterioration of disease with the development of aortic aneurysm, aortic dissection or sudden death. Genetic testing plays an important role in the early diagnosis, standardized follow-up, screening of family members, genetic counseling and individualized treatment of HAD. This review focused on the application of genetic testing in the standardized diagnosis and treatment of HAD.
Inherited eye disease is a heterogeneous group of eye disorders caused by genetic defects, which has many genetic characteristics, such as multiple inheritance modes and numerous gene variation types. Over the past few decades, genetic testing has improved significantly, with more and more known disease-causing gene variants identified. With the rapid development of high-throughput sequencing technology, clinical diagnosis and treatment of eye genetic diseases have been accelerated, and molecular diagnosis of eye genetic diseases has become an important step in accurate diagnosis and treatment. How to correctly select and evaluate each kind of genetic testing technology, reasonably standardize the use of genetic testing technology, and provide patients with more accurate genetic counseling are problem that clinicians need to seriously consider.
Objective To study the latest research progress of the formation mechanism of cholesterol stone disease and forming factors of cholesterol stone disease and to provide new theoretical level and develop a new development direction for guiding clinical application. Methods The related literatures at home and abroad were analyzed, compared and summarized, and the current relevant research dynamic of cholesterol stone disease was sketched. Results The formation of cholesterol gallstone is closely related to the abnormal levels of serum lipids metabolism, bacterial and viral infection, and the expression of genes related to cholesterol gallstone. Conclusions The formation of cholesterol calculus disease is a kind of interaction and intricate disease process involving of environmental factors, genetic factors, and biological factors. Although there has been a lot of blood lipid, protein correlation research with cholesterol stone, there are also many studies such as using gene transplantation and gene knockout, but gene technology of cholesterol stone disease diagnosis and treatment is expected to become the new hot research topic.
Paediatric retinal disease is the most important part of paediatric ophthalmology. It usually manifests as leukocoria or yellow pupil, typically in retinopathy of prematurity, familial exudative vitreoretinopathy, persistent hyperplastic primary vitreous, Coats disease and retinoblastoma. It also can be manifested as nystamus poor visual fixation or progressive worsening of visual function, typically in Leber congenital amaurosis, Stargardt disease, Best disease and cone and rod dystrophy. Paediatric retinal diseases can be roughly divided into acquired, hereditary and congenital developmental abnormalities. With the development of gene and stem cell technologies, the advent of new medicine, equipments and new techniques, the concept of diagnosis and treatment in paediatric retinal diseases is also changing. In China, the level is improving progressively in both clinical and research areas of paediatric retinal diseases.
ObjectiveMitochondrial encephalomyopathy is a series of diseases that drag in central nervous system and generalized muscles. The pathogenesis of the disease is lack of ATP for the dysfunction of mitochondria. The misdiagnosis rate of the disease is high and the purpose of this study is to improve the recognition and diagnosis of mitochondrial encephalomyopathy and thus, clinicians could take rational treatment in time and improve patients' prognosis. MethodsThe clinical data of 11 patients with mitochondrial encephalomyopathy were analyzed including the physical data, clinical presentations, laboratory data, neuroimaging findings, muscle biopsy, genetic testing, treatment and prognosis. Reviewing literature and summarizing the clinical characteristics of mitochondrial encephalomyopathy. ResultsAmong the 11 patients with mitochondrial encephalomyopathy, the mean age was 17 years old. 1 case had family history. 7 cases were misdiagnosed in the first clinic visit. The onset of the 11 cases, 9 were paroxysmal and 2 were hidden. In the course, 10 cases had an epileptic seizure. Among the 9 cases who took the determination of serum lactate, 8 was in high level.9 cases had MRI examination and all found abnormality, 10 patients had EEG examination, and 9 cases found abnormality, 6 cases had muscle biopsy and all found the ragged red fiber(RRF). 6 cases had molecular genetic testing, and all found mutations in mitochondrial DNA. Among the 10 cases who had epileptic seizure, 3 cases can be controlled with single kind of antiepileptic drug. The other 7 cases had a recurrence of epilepsy with single kind of antiepileptic drugs, but can be cotrolled after drug adjusting or drug combination. ConclusionMitochondrial encephalomyopathy is often accompanied by seizure, which is usually found in children, and also often accompanied by systemic muscle symptoms. The clinical manifestations of the disease is not typical, but is complex and varied symptoms, so the clinical misdiagnosis rate is high. Mitochondrial encephalomyopathy mainly involves the main intracranial artery distribution area (parietal lobe, temporal lobe, occipital lobe, etc.) in central nervous system, and can involve more than one part. Patients with mitochondrial myopathy brain are usually detected the elevation of serum lactate levels, but if the lactic acid level is normal, it does not rule out the possibility of the disease, the confirmation of the disease is mainly by muscle biopsy or genetic tests. There is no specific treatment for mitochondrial encephalomyopathy till now, and it still give priority to symptomatic treatment. And the prognosis is poorer.
