International Journal of Pediatrics 2018;45(2):84-87
Kawasaki disease(KD) is an acute systemic vasculitis that most commonly involves coronary artery.It is one of the leading causes of acquired heart diseases,but with an unclear mechanism.At present,in the pathological progress of cardiovascular diseases,oxidative stress (OS) has been demonstrated to play an important role.It damages the function of intravascular endothelial cells and weakens the structure of subendothelial layer and tunica media,reducing vascular elasticity and leading to long-term cardiovascular events.In KD patients,it has been believed that OS is likely to be involved in the pathogenesis of coronary artery lesion.Hence,based on the latest studies about KD,this paper reviewed the role of OS in pathophysiological mechanisms of vascular endothelial dysfunction,the possibility of antioxidant pharmacotherapy as a prevention from coronary artery lesion.

Hemoptysis in childhood is a common clinical manifestation whose severity depends on the rate at which hemoptysis occurs and the degree of bleeding.Hemoptysis occurs for a variety of reasons,among which hemopty-sis correlated with vessels is one of the factors.Although the incidence rate is not common,it is mostly the first cause of hemoptysis.Hemoptysis correlated with vessels exit a relatively backward diagnosis in clinical which due to the gradual process of the diagnosis,and its treatment and prognosis of the disease depends on the type,number,morphology of ab-normal vessels and degree of bleeding.It is important to earlier recognize hemoptysis correlated with vessels,develop a standardized diagnostic procedure,setup appropriate treatment plans and timing for medical staff so as to improve the diagnosis and treatment of the disease and reduce the incidence of complications and hemoptysis recurrence rate.

The difference in serum calcium levels between patients with typical hyperthyroidism and apathetic hyperthyroidism was analyzed. Serum calcium levels in patients with apathetic hyperthyroidism were higher than those in patients with typical hyperthyroidism, while bone-specific alkaline phosphatase levels were lower. The atypical manifestation of apathetic hyperthyroidism may be due to the significant elevation of serum calcium level.

Objective To study the effects of constant and intermittent high glucose on the apoptosis of cultured bovine retinal capillary pericytes (BRPs), and to investigate the role of mitochondrial apoptotic pathway in the apoptosis of BRPs. Methods After being cultured under glucose with different concentrations tot 6 days, the change of uhrastructure of BRPs was observed under electronmieroscope, the apoptosis of pericytes was detected by TUNEL method, the mitochondrial inner transmembrane potential (△Ψm) was detected by laser scanning confocal microscopy, the change of cytochrome c (cyt-c) was assayed by spectrophotometer and the expression of apoptotic genes was detected by immunohistochemical method and RT-PCR. Results (1) BRPs showed typical changes of apoptosis in constant and intermittent high glucose concentrations. The apoptosis induced by constant high glucose concentration was more obvious than that by intermittent high glucose. (2) Constant and intermittent high glucose concentrations obviously decreased △Ψm compared with control group. The △Ψm of BRPs was correlated negatively with the apoptotie rate of BRPs (r = - 0.89, P < 0.01) ; (3) Constant and intermittent high glucose concentrations increased the release of cyt-c from mitochondria to cytoplasm, and the concentration of cyt-c in the cytoplasm was correlated positively with the apoptotic rate of BRPs (P < 0.01) ; (4) Constant and intermittent high glucose concentrations increased the expression of proapoptotie gene Bax and decreased the expression of prosurvival gene Bcl-2, resulting in increased Bax/Bcl-2 ratio. Bax/Bcl-2 ratio was negative correlatied with the △Ψm of BRPs, and positively eorrclaticd with the concentration of cyt-c in cytoplasm and apoptotic rate (both P < 0.01).Conclusion Constant and intermittent high glucose concentrations could decrease △Ψm, increase the release of cyt-c and induce the apoptosis of BRPs, the effects being stronger with constant high glucose concentration. The mitochondrial apoptotic pathway plays an important role in the apoptosis of BRPs, in which Bax and Bcl-2 are involved.
