1.Advances of human leukocyte antigen in juvenile idiopathic arthritis
Journal of Clinical Pediatrics 2010;(2):193-196
Juvenile idiopathic arthritis (JIA) is the most common chronic arthropathy in childhood. Immune and genetic factors take part in the development of JIA and influence its consequence. Studies have identified association between JIA and genes encoding the human leukocyte antigens (HLA) . In this article we discuss the principles behind genetic studies of complex traits like JIA, and comprehensively catalog HLA candidate gene associated with JIA to date, and review several validated associations. Studies indicate that the HLA-Ⅰ, Ⅱ gene and their products play an important role in JIA pathogenesis, clinical course, hormonal effect and prognostic judgment. Studies in different ethnic groups indicate the main relationship between JIA and HLA is concentrated upon A, DR and DQ loci, especially the HLA-Ⅱ gene and some haplotypes. The different type of JIA is always with different HLA susceptible locus and protective locus. Different race, different region and different social environment also affect the JIA's susceptible gene polymorphism. Finally we discuss the problems existed in the study of JIA susceptibility and HLA polymorphism.

RESULTS:Multi-target treatment for re-fractory class Ⅳ+Ⅴ lupus nephritis achieved efficacy:the patient got higher plasma albumin and lower 24 h urine protein quantity af-ter 14 days;the patient suffered from secondary pulmonary infection and high blood pressure;physicians adopted the pharmacist’s suggestion so that pulmonary infection and blood pressure had been controlled. CONCLUSIONS:To ensure the effectiveness and safe-ty of the multi-target treatment,clinical pharmacists should formulate individualized treatment,focus on the possible ADR and provide phamaceutical care in the field of blood pressure monitoring,infection control,etc. when participating in multi-target treatment.
5.N 6-methyladenine methylation regulators and cancer
Journal of International Oncology 2021;48(2):96-100
N 6-methyladenine (m 6A) is the most abundant internal RNA modification found in a variety of eukaryotic messenger RNAs and long non-coding RNAs, which is dynamically regulated by m 6A methyltransferases and demethylases, and mainly works after recognized by m 6A binding proteins. m 6A is involved in almost every step of the RNA life cycle, including RNA transcription, splicing, localization, nuclear transport, translation, and degradation. Disorder of m 6A modification can lead to RNA dysfunction and abnormal gene expression. m 6A modification regulators express abnormally in various cancers, and play an important role in cancer formation, proliferation, differentiation, invasion and metastasis.

Objective By quantitative tissue velocity i maging(QTVI),to observe longitudinal wall motion characteristics during isovolumic contraction, ejection, isovolumic relaxation, early relaxation, atrial systole phases in regional myocardium of myocardial infarction patients with three diseased blood vessels, and to assess postsystolic shortening in isovolumic relaxation phase and its clinical meanings. Methods Left ventricular regional myocardium of 30 myocardial infarction patients (MI group) and 30 non-cardiac disease subjects (control group) was assessed by QTVI. After dynamic images were collected and information was analyzed off-line, left ventricular myocardial velocity and time velocity integral profiles were acquired along long axis asynchronously in basal and middle segments of different walls, peak velocities (V IC , V S, V IR , V E, V A) during different phases and maximum time velocity integral (TVI max )in regional myocardium was measured. Results Peak velocities(V IC , V S, V IR , V E, V A) in different segments of left ventricular regional myocardium in MI group were lower than those of control group, especially more obviously in infarcted segments. Peak velocity amplitude in ejection declined, but it had positive velocity spike; abnormal positive velocity in isovolumic relaxation phase suggested postsystolic shortening. What's more, time velocity integrals in some segments of MI group had two wave crests, reached maximum in isovolumic relaxation phase, but were still lower than that of control group. Conclusions Systolic and diastolic function in MI patients with three diseased blood vessels are apparently impaired; abnormal movement in isovolumic relaxation phase suggests existence of postsystolic shortening and abnormal wall motion in regional myocardium.V IR is a marker of abnormal regional wall motion and ischemic myocardium.
