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 2.11.0.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

Otjective To study whether there is the apoptosis of neural cells and the expressionof Bcl-2 protein in intracerebral hemorrhage (ICH) in model of rats, for the further understanding the mechanism of the delayed damage of the neural cells around the hematoma after ICH. Methods Fifty SD rats were randomly divided into 5 groups, ten in each. With the Group A as the control, the rest 40 were used to set up intracerebral hemorrhage model. The brains were taken out at 12th, 24th, 48th and 72th hours, respectively. Apoptosis cells were detected with terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL), and the expression of Bcl-2 protein was detected with immunochemical stainging methed (SP). Results In the control group, no apoptosis cells and Bcl-2protein were detected. In rest groups, the apoptosis cells and Bcl-2 protein were expressed in different degree.Apoptosis rates verified and corresponded with the time after ICH, with the peak at 48th -72th hour after hemorrhage.The peak rate of apoptosis cells was (24. 50± 2.69)% and Bcl-2 protein expression was (20. 76 ± 1.97)% . There was significant difference between the experimental groups and control (P<0.05), and no linear relationship between the apoptosis rate and the expression of Bcl-2 protein. Conclusion Apoptosis may be an important factor in the secondary trauma of ICH. There is a time leg after hemorrhage. All this is instructive to clinical treatment in time. Bcl-2 protein keeps increasing in a certain time after hemorrhage, but not synchronize with the cell apoptosis. This indicates that bcl-2 has the effect to reduce the apoptosis of neural cells.

Objective To observe the inhibition effect of recombinant human monocyte chemoattractant protein- 1(MCP- 1) on implantation and growth of human osteosarcoma cells. Methods The method of protein fusion was used for the expression of MCP- 1 in b.coli and then the MCP- 1 was extracted and purified. Fifty nude mice were divided into 10 groups. For A1- 4 groups, the 5 mice in each group were locally injected with doses of 1? g, 10? g, 100? g, 1 mg of MCP- 1 at the same time when 4.4? 106 osteosarcoma cells were implanted in vivo. For B0- 4 groups, 5 mice in each group, the injection were given 2 weeks later when there was the formation of the tumor mass at doses of 0? g(0.2 ml normal saline), 1? g, 10? g, 100? g, 1 mg of MCP- 1 every other day. Five mice in group C were injected with dose of 0.2 ml NS as control. Results Implantation of osteosarcoma cells were completely prevented among mice of group A2- 4, tumor inhibiting effect even in group A1 and the rate of tumor inhibition was 69.69% . AKP values in mice of group A1- 4 were much lower than those of group B0(P

The gerbil model in this study was induced by 30 min of bilateral carotid occlusion and 120 min of reperfusion. Verapamil ( 0.5 mg/kg)was given intravenously 10 min before ischemia, or 5 min after bilateral carotid occlusion. Local cerebral blood flow was determined by the hydrogen clearance teachnique. Brain water content was detected by the wet and dry methods. We conclude that verapamil used in this model may improve post-ischemic hypo-perfusion, increase local cerebral blood flow in ischemic region (P

This study was aimed to isolate and characterize of chemical constituents in a traditional Mongolian medicine HERBA CLEMATIS. Normal and reverse phase coloumn chromatography, gel filtration chromatography sephadex LH-20, and preparative HPLC were used for isolation and purification compounds from the water extraction of the arial part ofC. aethusaefoliaTurcz. The planar structures and spatial configurations of isolated compounds were identified by high resolution MS, 1D and 2D NMR, and other spectrographic methods. The chemical research on the Mongolian medicine results 6 compounds, dihydrodehydrodiconiferyl alcohol (1), syringaresinol (2), pinoresinol (3), epi-pinoresinol (4), lirioresinol B dimethyl ether (5) and loliolide (6).
