This article was a perspective study on natural pigment's new microbial resources,culture conditions,fermentation processes and genetic engineering strains,which provides some future direction for the development and application of natural pigment.

Objective To analyze the clinical features of organic damages in Kawasaki disease(KD),and to improve the diagnosis and treatment level.Methods Two hundred and two cases with KD admitted in Children's Hospital Affiliated to Capital Institute of Pediatrics from Jan.2000 to Oct.2007 were reviewed,and their blood routine,urine,stool routine,liver function,kidney function,chest X-ray,and so on,were investigated.The incidence of organic damages in KD was evaluated.Results Among the 202 KD children,137 were male and 65 were female,the male-female ratio was 2.11.0.Most of them were infants,and 71.3% of them were younger than 3 years old.The damages of hematological system were detected in 78/202 cases(38.6%),respiratory system 76/202 cases(37.6%),cardiovascalar system 68/202 cases(33.7%),urinary system 52/202 cases(25.6%),digestive system 23/202 cases(11.4%),and central nervous system 3/202 cases(1.5%).On the other hand,3 cases complicated with septemia,1 case with juvenile rheumatoid arthritis and 1 case with Henoch-Schonlein purpura.Conclusions The data indicate that the incidence of hematological system involvement in the sick-children with KD were highest,with more than 2 organs involved simaltaneously.Many organic damages were involved in KD and diverse clinical manifestation could be found.Physicians should understand not only the typical features but also the rare symptoms and organic damage so as to prevent misdiagnosis and improper treatment.J Appl Clin Pediatr,2009,24(1):31-32

Hydrogen sulfide is found to be the third gasotransmitter.It exerts extensive biological effects in nerve system,cardiovascular system,gastrointestinal system,and so on.In cardiovascular system,it exerts the function of vasorelaxation,inhibition of vascular smooth mu-scle cells and cardioprotection.It is also concerted with many cardiovascular diseases such as pulmonary hypertension,hypertension,coronary heart disease,atherosclerosis.This review discusses the latest research progress in the significance of hydrogen sulfide in cardiovascular diseases.

Exhaled gaseous signal molecules such as nitric oxide(NO),carbon monoxide(CO) and hydrogen sulfide(H2S) can be measured with a non-invasive technique.The fraction of NO level in exhaled gaseous of patients with airway inflammatory illness(such as bronchial asthma) significantly increases.No in exhaled gaseous is one of the markers in the diagnosis of asthma,and it is also a marker of anti-inflammatory response for patients with asthma.The fraction of CO level in exhaled gaseous of patients with bronchial asthma is also si-gnificantly elevated.Both NO and CO in exhaled gaseous in other airway inflammatory illness,such as chronic obstructive pulmonary disease,chronic bronchitis and cystic fibrosis are also evidently changed.Measuring exhaled gaseous signal molecules can provide important basis for the diagnosis and treatment of airway inflammatory illness.

Objective To explore the effect of the ?-blocker —metoprolol on the treatment of vasovagal syncope(VVS) in children.Methods Twenty-nine children with unexplained syncope and positive responses to head-up tilt test(HUT) were included in the study.Sixteen of them took metoprolol(treatment group) and 13 of them took vitamin B or oryzanol (control group) at least 2 weeks and HUT were repeated and syncope episodes were observed.Results In treatment group,9 of 16 patients had no syncope episode while 5 of 16 patients had fewer syncope episodes,1 case had more syncope episodes,and 1 case remained the same.HUT were repeated and 6 of 9 cases had negative outcome.In control group,1 of 13 patients had no syncope episode while 5 of 13 patients had fewer syncope episode,3 cases had more syncope episodes and 4 cases remained the same.HUT were repeated and 3 of 7 cases had ne-(gative) outcome.Conclusion These results indicate that adminstering metoprolol orally may be effective for VVS in children.
