1.Relationship between gut microbiota and Kawasaki disease
International Journal of Pediatrics 2021;48(5):291-294
Kawasaki disease is a disease based on systemic vasculitis, which has become the most common disease in children with acquired heart disease, but its etiology and pathogenesis remain unclear.The homeostasis of the gut microbiota plays an important role in the maturation of the body′s immune system and immune regulation.The disorder of the gut microbiota is involved in a variety of inflammatory and immune diseases in children.Studies have found that there are changes in the composition of gut microbiota in children with Kawasaki disease.Gut microbiota disorders are related to the occurrence and development of Kawasaki disease, with the immune system function affected.Various mechanisms such as intestinal mucosal barrier dysfunction, immune inflammation, oxidative stress and metabolite effects promote the pathogenesis of Kawasaki disease.This article reviews the research on the relationship between gut microbiota and Kawasaki disease.

6.Exercise management of children with Kawasaki disease
International Journal of Pediatrics 2021;48(11):732-736
In order to ensure that children with Kawasaki disease avoid the risk of cardiovascular accidents and even sudden cardiac death during exercise, it is of important clinical significance to formulate scientific, effective and safe exercise guidance for all children with Kawasaki disease.Physical activity mainly includes three types: activities of daily living, leisure sports and competitive sports, which are divided into low-intensity, medium-intensity and high-intensity according to the activity intensity.All sports activities are a combination of static exercise and dynamic exercise.Increasing static exercise requires a higher percentage of maximum voluntary contraction, while increasing dynamic exercise requires a higher oxygen consumption.For all children with Kawasaki disease, physical activities and sports management should be carried out according to the risk of coronary artery disease.When giving exercise guidance, the four factors including exercise frequency, intensity, time and type should be fully considered based on medical history, physical examination and necessary auxiliary examinations, and should be dealt with from dynamic exercise and static exercise.Children will be given safe and beneficial individualized guidance to ensure the best physical condition.

AIM:To investigate the effect of microRNA-429 (miR-429) on the expression of occludin (Ocln) in intestinal epithelial cells ( IECs) and intestinal epithelial barrier function in diabetic mice.METHODS:Diabetes mel-litus mouse model was induced by intraperitoneal injection of streptozocin.The expression of miR-429 in IECs of diabetic mice was inhibited by antagomiRNA-429 injected via tail vein.The expression of miR-429 and mRNA expression of Ocln were detected by real-time PCR.The protein expression of Ocln was determined by Western blotting and immunohistochem-istry.The urinary lactulose/mannitol ratio was measured by gas chromatography.The plasma LPS concentrations in the mice were measured by chromogenic end-point TAL kit.RESULTS:The results of real-time PCR confirmed that the ex-pression of miR-429 in IECs of diabetic mice was remarkably inhibited by tail-vein administration of antagomiRNA-429, and resumed to similar level of normal mice on the 6th day after the administration.After suppressing the level of miR-429, the expression of Ocln in IECs of diabetic mice increased significantly (P<0.05), while the urinary lactulose/mannitol ra-tio and the plasma LPS concentration decreased obviously ( P<0.05 ) .CONCLUSION:AntagomiRNA-429 effectively suppresses miR-429 expression in IECs of diabetic mice, and then enhances the expression of Ocln and partially resumes the intestinal epithelial barrier function.

Objective To evaluate perioperative management of MEN 2A patients with medullary thyroid carcinoma after bilateral pheochromocytomas removal.Methods Seven cases of MEN 2A from three families were diagnosed as medullary thyroid carcinoma and adrenal pheochromocytoma by biochemical tests and imaging examinations.All had histories of operations due to medullary thyroid carcinoma and contralateral adrenal pheochromocytoma.Direct sequencing of entire exons was performed in all patients.Firstly they underwent laparoscopic surgery for pheochromocytoma, then after stetoids replacement they underwent total thyroidectomy and bilateral cervical lymph nodes dissection.Results One family had the combined C634Y/D707E mutations of RET mutation.The other two families had C634Y mutation and C634R mutation separately.All patients had histories of adrenal insufficiency because of bilateral laparoscopic adrenal pheochromocytomas removal.They suffered from medullary thyroid carcinoma at the same time and needed to do total thyroidectomy and bilateral cervical lymph node dissection.Under perioperative steroids treatment and closely monitoring, they successfully went through the surgery.No adrenal crisis or related complications happened.Conclusions MEN 2A patients in this study had RET mutations and D707E mutation is a newly discovered mutation.Patients of adrenal insufficiency face the risk of adrenal crisis after a major operation.Correct perioperative monitoring and management can avoid complications.

Objective To study the mechanism of oxidative stress involved in the pathogenesis and relapse of acute monocytic leukemia (M5 ).Methods We detected reactive oxide species (ROS)levels,conducted plasma analysis obtained from 76 M5 patients at diagnosis and at relapse,and observed the ultrastructure of mitochondria of mononuclear cells in peripheral blood by transmission electron microscope.Results Compared with that in the control group,the average fluorescence intensity of intracellular ROS was significantly increased in M5 groups, especially in the relapse patients (P < 0.05 ).Low total antioxidative capacity (T-AOC)and antioxidant enzyme activity were characteristic of M5 at both diagnosis and relapse. However, lactate dehydrogenase (LDH ), malondialdehyde (MDA)and 8-hydroxy-2’-deoxyguanine (8-OHdG)increased significantly at both diagnosis and relapse (P < 0.05 ).Prominent ultrastructural abnormalities (mitochondrial swelling,outer membrane blebs,and aberrant cristae disorder)were present in patients with primary M5,and they were obviously abnormal in relapsing M5 patients.Conclusion Oxidative stress is the initiating factor of M5.Mitochondria are the main intracellular location for ROS generation.To maintain the dynamic balance between ROS and antioxidant defence may be the critical factor for preventing relapse.

ABSTRACT:Objective To detect the expressions of thioredoxin (TRX1)and c-jun-activation-domain binding protein-1 (JAB1)in patients with acute myelogenous leukemia (AML)and healthy controls,and measure the TRX1 level in AML patients at different stages for evaluating its clinical significance.Methods The expressions of TRX1 and JAB1 in leukemia samples were analyzed by RT-PCR and Western blot at mRNA and protein levels, respectively.The correlation between TRX1 and JAB1,and the relationship between the gene expression and peripheral blood leukocytes count were also analyzed.Furthermore,serum TRX1 was measured by ELISA.Results TRX1 and JAB1 expressions at both mRNA and protein levels were obviously upregulated in leukemia patients (P<0.05). TRX1 was positively related to JAB1 in both newly diagnosed and recurrent AML patients.And high levels of TRX1 and JAB1 expressions were associated with white blood cell (WBC)counts in AML patients (P<0.05).Moreover, abundance of TRX1 in serum was significantly greater in AML patients,especially in the patients with recurrent AML,than in healthy donors (P<0.05).Conclusion There is a positive correlation between the expressions of TRX1 and JAB1 ,which is closely related to the occurrence and progression of AML.
