Objective To study the features of Kawasaki disease (KD)with liver damage and investigate the possible related factors,and to improve the understanding of liver damage in KD patients.Methods The clinical data of 75 KD patients admitted from 2008 to 2013 were collected to retrospectively analyze the clinical features of liver damage,as well as routine blood test,C-reactive protein (CRP),erythro-cyte sedimentation rate (ESR),liver function,and abdominal ultrasound.Categorical data were analyzed by chi-square test;continuous data were expressed as mean ±standard deviation;comparison between groups was made by t test and multivariate stepwise regression analy-sis.Results The incidence of abnormal alanine aminotransferase (ALT)level in 75 cases was 32%,and 79.2% of these patients had a serum ALT level of less than 200 IU/L,including 3 patients with hepatomegaly,1 patient with jaundice,and 1 patient with splenomegaly, which accounted for 12.5%,4.2%,and 4.2%,respectively,of patients with liver damage.CRP and ESR were not found to be related to liver damage (t=1.560,P=0.123;t=1.291,P=0.201).There was significant difference in platelet count between patients with liver damage and controls (t=-3.228,P=0.003).No significant difference in white blood cell (WBC)count increase was found between the liver damage group and control group,but simultaneous increase in WBC count and platelet count was significantly associated with an in-creased risk of liver damage (P<0.05).Conclusion CRP and ESR are not found to be significantly related to the development of liver damage,but there is a close relationship between liver damage and abnormal platelet count.WBC count shows a certain relationship with liv-er damage.Clinicians should pay attention to these factors and take timely measures for intervention.

Objective To investigate the prevalence of anxiety and depression in adolescent children, and to explore influencing factors of anxiety and depression. Methods From May 2016 to September, 435 students at the age of 10~18 were randomly selected from primary school, middle school, high school in Weifang city. The Screen for Child Anxiety Related Emotional Disorders (SCARED) and Depression Self-rating Scale for Children (DSRSC) were used to evaluate the Clinical manifestation of students with anxiety and depression. A survey on the factors influencing anxiety and depression in adolescence was used to evaluate the related factors of students with anxiety and depression. Results The incidence rate of the anxious and depression of adolescent children in Weifang City was 20.6% and the average age was (12.38±3.58). The occurrence rate of anxious and depression was higher in girls than in boys (26.5%vs. 15.7%, P<0.05). Personal unhealthy (OR=0.387, P=0.001), lack of parental accompaniment (OR=0.671, P=0.020), low parental educational levels(OR father=0.338, P=0.001; OR mather=0.262, P=0.001), poor parental relationship (OR=1.049, P=0.008), bad parenting styles (OR=0.471, P=0.016) were risk factors of anxious and depression in adolescent children (P<0.05). Conclusion Adolescent girls are the high incidence population of emotional disorder, especially in early adolescence. Lack of parental accompaniment, low parental educational levels, poor parental rela-tionship, bad parenting styles are closely related to anxiety and depression.

Microglial cells are the resident immune cells of brain. The activated microglia produces a range of deleterious substances, which plays an important role in the inflammation of post-stroke, such as superoxide, nitric oxide, matrix metalloproteinases, etc. The activa-tion of microglia may involve triggering receptor expressed on myeloid cells-1, Toll-like receptors 4, peroxisome proliferator-activated re-ceptors, purinergic receptors, etc. Intervention targeted to microglial receptor is becoming a new strategy for ischemic stroke.

Objective To develop an LC-MS/MS method for determining the concentration of wogonin in dog plasma and investigate the pharmacokinetics and bioavailability by different administrations of wogonin in Beagle's dogs. Methods LC-MS/MS was employed in determining the concentration of wogonin with the selected ion monitoring model after liquid-liquid extraction with ethyl acetate of dog plasma samples. The lower limit of quantification was 0.105 μg/L. Target ions were at m/z 285.0→270.0 for wogonin and 373.3→305.3 for finasteride. In a randomized, self-control, and cross-over study, six male Beagle's dogs were treated with different administration methods in three test periods. Pharmacokinetic parameters were calculated with DAS software (Ver. 2.0). Results The calibration curve was linear in the range of 0.105-107.36 μg/L for wogonin in dog plasma samples. The main pharmacokinetic parameters of ig administration (native drug of 15 mg/kg and solution preparation of 5 mg/kg) and iv route were as follows: Cmax (2.5 ± 1.1), (7.9 ± 3.3), and (6838.7 ± 1322.1) μg/L, tmax (0.7 ± 0.3) and (0.3 ± 0.2) h for the both former, AUC0-1 (7.1 ± 2.0), (21.0 ± 3.2), and (629.7 ±111.8) μg·h/L. The absolute bioavailability of native and solution of wogonin were (0.59 ± 0.35)% and (3.65 ± 2.00)%, respectively. Conclusion The validated method is convenient, sensitive, and specific, and the improvement of wogonin solubility could remarkably increase the absolute bioavailability.

Autophagy plays an important role in the regulation of activation and inflammation of microglia after ischemic stroke. The interaction between autophagy of microglia and the inflammation mediated by microglia after ischemic stroke was complex and a large num-ber of molecules were involved. The receptors of microglia activation and related substances may be possible mechanism in the regulation of microglia autophagy. Autophagy inhibitors and microglia receptor targeting therapy may provide new strategies for the clinical treatment of ischemic stroke. This paper summarized the progress of microglia autophagy after ischemic stroke.
