Objective To investigate the impact and predictive value of high mobility group protein B1(HMGB1)and angiopoietin like protein 2(Angptl-2)on coronary artery damage in children with Kawasaki disease.Methods A total of 114 children with Kawasaki disease were selected and divided into the normal coronary artery group(85 cases)and the coronary artery lesion group(29 cases)according to the presence or absence of coronary artery lesions.The general clinical data of the two groups were compared.Enzyme linked immunosorbent assay was applied to detect serum levels of HMGB1 and Angptl-2 in children and compared between the two groups.Logistic regression was applied to analyze the influencing factors of coronary artery damage in children with Kawasaki disease.Receiver operating curve(ROC)was applied to analyze the predictive value of serum levels of HMGB1 and Angptl-2 for coronary artery damage in children with Kawasaki disease.Results The serum levels of HMGB1 and Angptl-2 were significantly higher in acute stage than those in remission stage(P＜0.05).Before treatment,the duration of fever,white blood cell count,erythrocyte sedimentation rate,procalcitonin and serum HMGB1 and Angptl-2 levels were significantly higher in the coronary artery lesion group than those in the normal coronary artery group(P＜0.05).Logistic regression analysis showed that the duration of fever,white blood cell count,erythrocyte sedimentation rate,procalcitonin,HMGB1 and Angptl-2 levels before treatment were all independent risk factors for coronary artery damage in children with Kawasaki disease(P＜0.05).The area under the curve(AUC)of serum HMGB1 and Angptl-2 for diagnosing coronary artery damage in children with Kawasaki disease was 0.907(95%CI:0.838-0.953)and 0.857(95%CI:0.780-0.916),respectively,with cut-off value of 59.62 μg/L and 10.35 μg/L,respectively.The AUC,sensitivity and specificity of the combined diagnosis of coronary artery damage in children with Kawasaki disease were 0.958(95%CI:0.903-0.987),93.10%and 90.59%,respectively,which were better than their individual diagnose.Conclusion The serum levels of HMGB1 and Angptl-2 are obviously elevated in children with Kawasaki disease complicated by coronary artery damage,and the combined detection of HMGB1 and Angptl-2 levels in serum can provide a good prediction for coronary artery damage in children with Kawasaki disease.

ObjectiveTo investigate the protective effect of Zuoguiwan against ⁶⁰Co-γ ray-induced premature aging of rats based on the phosphatidylinositol-3-kinases/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway. MethodSixty sexually mature female SD rats were irradiated with ⁶⁰Co-γ rays （6.0 Gy， LD₄₀） for 24 h at one time. Then they were randomized into model group， Bujiale group （0.18 g·kg^-1·d^-1）， Bujiale （0.09 g·kg^-1·d^-1） + high-dose Zuoguiwan group （23.625 g·kg^-1·d^-1）， high-dose Zuoguiwan group （23.625 g·kg^-1·d^-1）， medium-dose Zuoguiwan group （9.45 g·kg^-1·d^-1）， and low-dose Zuoguiwan group （4.725 g·kg^-1·d^-1）. The administration （once a day） lasted 21 days. Serum indexes ［follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E₂）］ of rats were detected by enzyme-linked immunosorbent assay （ELISA）， and morphological changes of ovarian tissues were observed based on hematoxylin and eosin （HE） staining. The apoptosis rate of granulosa cells was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling （TUNEL） and the protein expression of phosphorylated （p）-PI3K， p-Akt， p-mTOR， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in ovarian tissues by Western blot. ResultCompared with normal group， model group demonstrated increase in serum FSH （P<0.01）， decrease in E₂ （P<0.05）， and reduction of follicles and luteum in early ovary （P<0.01）. Moreover， the elevation of apoptosis rate of granulosa cells （P<0.01）， down-regulation of p-PI3K， p-Akt， p-mTOR， and Bcl-2 in ovarian tissue， and increase in expression of Bax were also observed in the model group as compared with the normal group （P<0.01）. In comparison with the model group， the administration groups showed rise of the number of early ovarian follicles， decrease in the apoptosis rate of granulosa cells， increase in the expression of p-PI3K， p-Akt， p-mTOR， and Bcl-2， and down-regulation of Bax， particularly the Bujiale + high-dose Zuoguiwan group（P<0.05，P<0.01）. ConclusionZuoguiwan protects radiation-damaged ovary by activating the expression of PI3K/Akt/mTOR protein in ovarian tissue， increasing Bcl-2， and inhibiting the expression of Bax.
