Journal of China Medical University 2017;46(3):219-222
Objective To summarize and discuss the laboratory characteristics of children with incomplete Kawasaki disease(IKD)in recent 10 years and provide some evidence for early diagnosis. Methods A retrospective review was performed on 67 children with IKD and 67 children with respiratory tract infection(bacterial infection)from 2005 to 2015 in the First Hospital of China Medical University. Results The age of chil-dren with IKD varied from 2 months to 11.3 years,with the average age of 31 months. Totally 86.5%of the children were less than 5 years old. The male to female ratio was 2:1. The incidence of the disease in spring and summer was 72%. The incidences of the increasing of white blood cell ,C-reactive protein,alanine aminotransferase,aspartate aminotransferase,glutamyl transpeptidase,and platelet and the decreasing of hemoglobin and serum albumin were 82%,94%,27%,24%,45%,72%,61%,and 94%,respectively. Conclusion The levels of the hemoglobin(<109 g/L), serum albumin(<34 g/L),platelet(>393×109/L),C-reactive protein(>74 mg/L),alanine aminotransferase(>51 U/L),and glutamyl transpepti-dase(>43 U/L)may have a certain reference value for the early diagnosis of IKD.

ObjectiveTo study transcriptional characteristics of type Ⅲ procollagen gene in systemic scleroderma (SS)-derived fibroblast clones and their regulation by Radix Salviae miltiorrhizae(RSM).Methods Eight fibroblast clones with different collagen-producing capacity were previously obtained from patients with SS and normal human controls.Recombinant plasmids containing different deletions of the human alpha 1 chain of type 3 procollagen(COL3A1) gene promoter were constructed,and transiently transfected into the fibroblast clones.Dual-luciferase reporter assay system was used to evaluate the activities of these recombinants in the fibroblast clones and to select a proximal transcriptional regulatory sequence.Then,the fibroblast clones were transfected with the plasmid containing the selected regulatory sequence(phCOLH30.1) followed by the treatment with RSM injection(1 g/L) and active monomers of RSM,including salvianolic acid B(5 mg/L),tanshinone Ⅱ A (5 mg/L),danshensu(20 mg/L) and protocatechuic aldehyde(5 mg/L),for 48 hours.The transfected fibroblast clones receiving no drug treatment served as the water-soluble control,and those treated with only dimethyl sulfoxide as the lipid-soluble control.Subsequently,the fibroblasts were lysed and subjected to the quantification of cellular proteins and determination of luciferase activity.The activity of recombinant promoters was compared by t test for the selection of proximal transcriptional regulatory sequence,and the activity of phCOLH30.1 by two-way analysis of variance in the RSM-interfering test(if there was interaction,one-way analysis of variance was conducted; and if there was no interaction,the main effect was tested after the removal of interaction item).ResultsOf the 6 recombinants,the recombinant containing COL3A1 proximal promoter from -96 bp to +16 bp(phCOLH30.1) showed the highest transcriptional activity in nearly all of the fibroblast clones,and the activity was positively correlated with the collagen-producing capacity of fibroblast clones.Compared with the water-soluble control,RSM injection significantly downregulated the activity of phCOLH30.1 in fibroblast clones with high and low collagen-producing capacity from patients with SS (2.261 ± 0.619 vs.3.879 ± 0.309,1.462 ± 0.291 vs.2.150 ± 0.262,both P < 0.01) and normal human controls (1.681 ± 0.263 vs.3.039 ± 0.271,1.121 ± 0.361 vs.2.223 ± 0.247,both P < 0.01),salvianolic acid B decreased the phCOLH30.1 activity in SS-derived high collagen-producing fibroblast clones (2.309 ± 0.524,P < 0.01 ) and in the normal control fibroblast clones with high and low collagen-producing capacity (2.126 ± 0.320 and 1.976 ± 0.362,both P < 0.05).Tanshinone Ⅱ A only downregulated the phCOLH30.1 activity in SS-derived high collagen-producing fibroblast clones compared with the lipid-soluble control(2.975 ± 0.666 vs 5.379 ± 0.238,P < 0.01 ).Neither danshensu nor protocatechuic aldehyde showed inhibitory effects on phCOLH30.1 activity in SS-derived or normal control fibroblast clones.ConclusionsThe type Ⅲ procollagen gene is activated at the transcriptional level in high collagen-producing fibroblast clones from patients with SS,and the activation could be suppressed by RSM injection,salvianolic acid B and tanshinone Ⅱ A.

Objective To study the transcriptional regulation of type Ⅰ procollagen gene in systemic scleroderma(SS)-derived high collagen-producing fibroblast clones by Radix Salviae Miltiorrhizae(RSM).Methods Fibroblast clones with different collagen-producing capacity were previously obtained from patients with SS and normal human controls,and divided into 5 groups to be treated with RSM(1 g/L)injection,its water-soluble active monomers including sodium danshensu(20 mg/L),salvianolic acid B(5 mg/L)and protocatechuic aldehyde(5 mg/L),and lipid-soluble active monomer(tanshinone Ⅱ A,5mg/L)respectively.The fibroblast clones incubated with no drugs served as the water soluble negative control group,and those with dimethyl sulfoxide(DMSO)as the lipid soluble negative control group.MTT assay was performed to evaluate the proliferation of the fibroblast clones after 1-,3-,5-,and 7-day treatment,transient transfection and dualluciferase reporter assay system to quantify the relative activity of collagen type Ⅰ,alpha 1(COL1A1)proximal promoter in these fibroblast clones.Results The inhibitory effect of RSM and its active monomers on the proliferation of fibroblast clones was inapparent within the initial 3 days(P > 0.05),but was enhanced with incubation time.A significant difference was observed in the proliferation level of fibroblast clones between RSM group and water-soluble negative control group on day 5(q′ =3.22,P < 0.01),between RSM,salvianolic acid B,protocatechuic aldehyde groups and the water-soluble negative control group(q′ =4.74,3.03,2.56,all P <0.05)on day 7,and between tanshinone Ⅱ A and lipid-soluble negative control group on day 5 and 7(t =2.22,2.15,both P < 0.05).RSM injection,tanshinone Ⅱ A and protocatechuic aldehyde significantly inhibited COL1A1 proximal promoter activity in SS-derived and normal control fibroblast clones(all P < 0.01),and the former two drugs preferentially downregulated COL1A1 proximal promoter activity in SS-derived high collagenproducing fibroblast clones.Significantly different COL1A1 proximal promoter activity was observed in SS-derived high and low collagen-producing fibroblast clones between water-soluble negative control group and RSM injection group(12.019 ± 0.830 vs.4.445 ± 1.061,5.388 ± 0.480 vs.2.856 ± 0.597,F=31.78,P< 0.01),and between lipid-soluable negative control group and tanshinone Ⅱ A group(14.155 ± 0.672 vs.9.638 ±0.854,4.299 ± 0.252 vs.3.192 ± 0.450,F=24.10,P< 0.01).Conclusions RSM inhibits the transcription of COL1A1 gene in SS-derived high collagen-producing fibroblast clones,which may be mainly attributed to tanshinone Ⅱ A and protocatechuic aldehyde.
